Further, the equipment unit 30 may be provided with a seat or a bed so that it can be used as an operation space, a temporary relief space, or the like after arriving at the disaster site.

An emergency vehicle equipment 31 including a siren 32, a red light 33, an installation base 34, and a moving mechanism 35 is housed in the upper part of the inside of the equipment unit 30. A siren 32 and a red light 33 are installed on the installation base 34. For example, the moving mechanism 35 is configured by combining a plurality of legs and a rotating shaft, and lifts up the installation base 34 on which the siren 32 and the red light 33 are installed in the upward front direction, and also in the downward rear direction. Lift down to. The emergency vehicle equipment 31 is normally lifted up by a moving mechanism 35 so that a part thereof covers a part of the cabin 12, but for example, the entire cabin 12 is tilted forward in order to maintain the engine. In this case, the moving mechanism 35 can lift down the inside of the equipment unit 30 so as not to interfere with the cabin 12. The moving mechanism 35 may move the installation base 34 only in the vertical direction or only in the front-rear direction.

Further, the emergency vehicle equipment 31 may be removed from the equipment unit 30 so that it can be mounted alone on the cabin 12.

A water storage tank may be mounted instead of the equipment unit 30.

Next, FIG. 2 shows a configuration example of the pump unit 20. FIG. 3 shows a usage example of the pump unit 20.

The pump unit 20 houses a control unit 21, a battery 22, an electric motor 23, and a pump 24 inside the housing 29. Further, the pump unit 20 has a solar cell panel 28 arranged on the outside of the ceiling of the housing 29. The solar cell panel 28 may be arranged on the side surface of the housing 29 or on the outside of the housing of the equipment unit 30.

The control unit 21 has an electric motor 23, a pump 24, an electric submersible pump (EWP) 41 (FIG. 3), a float type electric pump (FEP) 42, and an electric pump (EP) 43 (FIG. 3) according to an operation from the user. Controls the operation of. This facilitates control when water is discharged by relaying a plurality of pumps. The user can operate the control unit 21 on the machine side, or may be able to remotely control the control unit 21 using, for example, a mobile terminal such as a smartphone. Further, if the control program inside the control unit 21 can be rewritten, the version of the control unit 21 can be easily upgraded. Of course, the electric submersible pump 41, the float type electric pump 42, and the electric pump 43 may each be provided with a control unit separate from the control unit 21 so that the user can operate the electric submersible pump 41 individually.

It is assumed that the battery 22 is made of, for example, a lithium ion battery, an all-solid-state battery, or the like, and is precharged before being dispatched. However, the battery 22 may be charged with the electric power generated by the traveling engine, the generator, and the solar cell panel 28 mounted on the vehicle body 11. Further, the battery 22 may be charged from an AC power source (so-called outlet) or an EV charging device on the go. The battery 22 supplies driving power to the electric motor 23, the electric submersible pump 41, the float type electric pump 42, and the electric pump 43.

The electric motor 23 is connected to the rotating shaft of the pump 24, and drives the pump 24 to rotate by supplying power from the battery 22. The electric motor 23 and the pump 24 may be integrated. The pump 24 pressurizes the fire extinguishing water absorbed from the suction pipe 26 and discharges it to the water discharge hose 27 (FIG. 3). The pump 24 can be efficiently arranged in any direction regardless of the arrangement and orientation of the engine of the vehicle body 11.

It is desirable to use a vertical pump for the pump 24. By adopting the vertical pump, a fluid cyclone separator for removing pebbles, metal pieces, etc. that may be mixed with the absorbed water can be installed directly under the pump 24. Further, the pump 24 can be arranged compactly, and its maintainability can be improved. Further, the watertight structure of the pump unit 20 can be easily realized.

The electric motor 23 can be used as a regenerative generator by flowing water from a fire hydrant or the like into the pump 24 and rotating the rotating shaft of the pump 24 by the water pressure in an emergency other than when extinguishing a fire. The generated electric power can be stored in the battery 22.

Further, the pump unit 20 is provided with a hose accommodating space 25 at the bottom of the housing 29. The hose accommodating space 25 is provided with openings on the left and right surfaces, and the suction pipe 26 and the water discharge hose 27 can be taken out from either the left or right surface, and are wound parallel to the ground surface and placed flat. It is designed to be accommodated. As a result, the suction pipe 26 and the water discharge hose 27 can be easily pulled out and expanded. Moreover, it can be easily accommodated. Although the details will be described later, in the present embodiment, since the water discharge hose 27 can be diverted to the suction pipe, the hose storage space 25 may not accommodate the suction pipe but may accommodate a plurality of water discharge hoses 27. ..

In fire pump wheel 10 _1, the extinguishing water and float type electric pump 42 to be disposed is floated on the water surface during the electric water pump 41 and吸管26 attached to the tip of吸管26 is water, the pump 24 Water is absorbed through the suction pipe 26, pressurized, and discharged to the water discharge hose 27, and water is discharged from the cylinder tip 44 attached to the tip of the water discharge hose 27. The electric submersible pump 41 and the float type electric pump 42 may be made to absorb water at the same time, or may be made to absorb water into only one of them depending on the state of mud on the bottom of the water, dust on the water surface, and the like.

When it is necessary to assist or strengthen the water absorption capacity and the water discharge pressure by the pump 24, the suction pipe 26 and the water discharge hose 27 can be relayed by one or more electric pumps 43. Further, if the electric pump 43 is replaced with a higher performance one as needed, the water absorption capacity and the water discharge pressure can be easily enhanced.

According to fire pump wheel 10 _1, since the removably mounting the pump unit 20 with respect to the ladder frame 13 of the vehicle body 11, it is possible to combine the pump unit 20 to procure a generic vehicle not custom , It can be manufactured at a lower cost than a conventional fire-fighting pump vehicle in which a vehicle body and a fire-fighting pump are integrated. Further, if the pump unit 20 is standardized and standardized, mass production becomes possible and the production cost can be reduced. Furthermore, when inspecting and repairing the vehicle body 11, the pump unit 20 can be easily loaded and unloaded.

Further, if the vehicle body 11 is deteriorated first even though the pump unit 20 is still usable, only the vehicle body 11 is replaced and the pump unit 20 is diverted to use the fire pump vehicle. 10 ₁ it is possible to inexpensively update. Conversely, when the pump unit 20 has failed, since it is sufficient to replace the pump unit 20, it is possible to shorten the repair time of the fire pump wheel 10 _1.

Further, according to the pump unit 20, since the electric submersible pump 41 is used, the vacuum pump, which is required in the conventional fire pump, becomes unnecessary. This eliminates the need for an automatic outlet shutoff valve, a water stop valve, and a check valve. Further, since the suction pipe 26 does not generate a negative pressure, the negative pressure performance is not required, so that the water discharge hose 27 can be diverted. Further, the allowable range of the negative pressure performance (watertightness performance) of the pump 24 is expanded.

When a conventional fire pump is used over time, an electric vacuum pump or an electric compressor driven by the electric power of the battery 22 may be introduced. This makes it possible to perform a pressurization (positive pressure) test without using actual water in addition to the conventional pump negative pressure (vacuum) test by simply switching the air pipeline, and positive pressure and negative pressure can be tested. Both leak and simple leak tests can be done, for example in a fire department garage, without moving the vehicle to the water source, reducing the cost of routine inspections.

Further, since the pump unit 20 does not use the power source of the vehicle body 11, the pump drive device required for the conventional fire pump becomes unnecessary. As described above, since the pump unit 20 does not require various parts required for the conventional fire pump, maintenance and replacement of these parts are unnecessary, and failure factors can be reduced.

Furthermore,吸管26 fire pump wheel 10 ₁ is mounted, the water discharge hose 27, the electric water pump 41, a float-type electric pump 42, the electric pump 43, and by combining the cylindrical tip 44 appropriately, without using a pump 24, Multiple water discharge lines can be assembled. The water discharge line can be used, for example, for drainage work in a flood-stricken area or the like. Further, the water discharge line can be used for fire extinguishing work although the water pressure is lower than that through the pump 24.
