Abstract

PURPOSE:To enable effective cleaning of the inside of a pipe in an apparatus for cleaning pipes used for water and sewage facilities by installing a high- pressure water pipe connected to a high pressure pump in a water pipe, from which the main body of a cleaning machine is suspended to support it, connecting a joint to the high-pressure water pipe to receive high pressure water, and ejecting water from a nozzle attached to an expansion arm. CONSTITUTION:A pressure piping 6 for supplying water is installed in a pipe for water and sewage and connected with a high pressure pump. On the under part of the outer surface of the pipe 6, a rail-side joint 8 is installed. The opening of the joint 8 is always kept closed by energizing a closing plate 8b by a spring 8. A flat plate 6a is installed at both sides of the periphery of the pipe 6 in the axial direction to support the main body 1 of a cleaning machine through a roller 11 to be able to move freely. The main body 1 of the cleaning machine is equipped with a joint 7, which opens the closing plate 8b of the rail-side joint 8 and engages it, an expansion arm 2, and a cleaning nozzle 4 to receive cleaning water through a joint 7, so that cleaning water is ejected from the nozzle 4 for cleaning.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning storage pipes and piping of sewerage facilities.

[0002]

2. Description of the Related Art A storage pipe in a sewerage facility temporarily stores rainwater when a large amount of water is generated during a typhoon or heavy rain. At that time, however, sludge such as sand is mixed into the inflow water. Even if the inflow water is drained when it rains, sand etc. will accumulate in the storage pipe. Therefore, we wash it regularly.

The conventional mobile cleaning apparatus is generally of the type that runs on the floor of the pipe.

[0004]

However, the cleaning device has a problem that it cannot be cleaned because the cleaning device cannot run when a large amount of sludge is accumulated.

Therefore, in cleaning the pipe, it is necessary to perform the cleaning regardless of the accumulation of sludge in the pipe.

An object of the present invention is to provide a cleaning apparatus capable of cleaning the entire pipe regardless of the sludge accumulation state of the pipe.

Side joints are projected to eject pressure water, the opening of the rail side joint is closed with a closing plate, the closing plate is pressed with a spring to prevent pressure water leakage, and both sides of the water distribution pipe are surrounded. Install a flat plate parallel to the water pipe extension direction, hang a roller that rotates freely on the flat plate, hang the washing machine body on the flat plate through the roller, and attach the main body joint to the top of the washing machine body to attach the rail side. It receives pressure water by fitting it with the joint, confirms the positional relationship between the main body joint and the rail side joint, and controls the vertical movement of the main body joint,
A telescopic arm is attached to the lower part of the washer body to adjust the length freely, a washing nozzle is attached to the tip of the telescopic arm, and pressure water is discharged to wash the storage tank or piping.

EXAMPLE An example of the present invention will be described below. 1 to 3, 3 is a high-pressure pump for sending pressure water for cleaning, 6 is a water pipe attached to the upper part of the inner surface of a storage tank or pipe to be washed, and 8 is a lower part of the outer surface of the water pipe 6. A rail-side joint that is provided in a protruding manner to eject pressure water, 8a is a closing plate that closes the opening of the rail-side joint 6, 8b is a spring that presses the closing plate 8a to prevent leakage of pressure water, and 6a is a water pipe A flat plate mounted parallel to the water pipe extension direction on both sides of the outer periphery of 6, a roller 11 freely suspended by the flat plate 6a and freely rotating, and a flat plate 6a via the roller 11.
The main body joint 7 is attached to the upper part of the main body 1 of the washing machine and is fitted with the rail side joint 8 to receive pressure water. 1a confirms the positional relationship between the main body joint 7 and the rail side joint 8. A control unit 2 for controlling the vertical movement of the main body joint 7 is attached to the lower portion of the main body 1 of the cleaning device, and a telescopic arm 4 for freely adjusting the length is provided.
Is a cleaning nozzle that is attached to the tip of the telescopic arm 2 to discharge pressured water to wash the storage tank or the pipe. In a mobile cleaning device for the storage pipe and the pipe, the cleaning nozzle is installed along the moving rail attached to the upper part of the pipe. This is a cleaning device that can move the nozzle and move the nozzle by the telescopic arm 2 with a cleaning device that supplies the cleaning water from the moving rail by a joint. It is also a cleaning device that can be cleaned by the sprinkler method. .

That is, in this embodiment, a moving rail is provided on the pipe ceiling, and the main body can be washed regardless of the amount of sludge accumulated by moving the moving rail. By supplying it, there is no restriction on the range of movement by the hose for cleaning water, and there is no restriction on the capacity of the cleaning water tank when the cleaning water tank is installed in the main body itself. Since the cleaning is performed by injecting high-pressure cleaning water, the storage pipe cleaning device according to the present embodiment can perform cleaning regardless of the sludge accumulation amount of the pipe.

FIG. 1 shows an overall configuration of a storage pipe cleaning apparatus according to this embodiment, which comprises a moving water pipe 6, a cleaning machine body 1, a telescopic arm 2, a cleaning nozzle 4, and a high pressure pump 3. The main body 1 of the washing machine moves along the water pipe 6 to perform washing. The cleaning water is supplied by the high pressure pump 3, and the cleaning water is supplied to the main body by the rail side joint 8 and the main body joint 7 from the water distribution pipe 6.

The washing water taken into the main body is washed by jetting it at a high pressure from a nozzle provided in the telescopic arm 2 programmed to move along the inner surface of the pipe.

FIG. 2 shows a configuration diagram of the moving pipe and the main body.
The washing machine main body 1 suspended on the moving rail is the roller 1
It moves by the rotation of 1. A rail joint 8 is provided in the transfer pipe for each fixed section, and cleaning and transfer are repeated for each section.

FIG. 3 shows a detailed view of the joint portion.

The washing water after washing is collected in the drainage pit,
It is discharged by the drainage pump 9.

According to the present embodiment, it is not necessary to provide a washing water tank, a pump, etc. on the main body, so that the main body can be made compact.

Further, by arranging a small camera and monitoring the inside of the pipe, it is possible to perform partial cleaning by visual observation.

Another embodiment of the present invention will be described with reference to FIG.

The basic structure is similar to that of FIG. 1, but a sprinkler is provided instead of the telescopic arm, and the arm is rotated by the water pressure of the cleaning water to perform cleaning.
