Description
Technical field
The present invention relates to a kind of well cover for sewer, more particularly to a kind of automatic exhaust well cover for sewer.
Background technology
Municipal sewage system well lid is used to prevent pedestrian from falling into sewer, and can also prevent the rubbish on street from falling into lower water
Road and result in blockage, well cover for sewer is provided with osculum, rainwater that can be on venting street, and osculum can also play nature exhaust
Effect, but it is unobvious by effect that osculum is vented naturally, it is more poly- more which results in the biogas in sewer, only
Run into Mars and will result in blast.Particularly during the Spring Festival, child often likes throwing away firecrackers toward in well cover for sewer, even more
Easily causing blast causes dead and wounded accident.
As can be seen that how to exclude the biogas in well cover for sewer from the conventional Lessons for occurring, prevent biogas from accumulating
Poly- having turned into needs urgent problem.
The content of the invention
The present invention provides a kind of automatic exhaust well cover for sewer, and exhaust fan is controlled periodically to sewer by time controller
Biogas in well lid is excluded, and prevents the biogas in well cover for sewer from gathering.
The present invention solves the above problems and is adopted the technical scheme that：A kind of automatic exhaust well cover for sewer, including well lid
Body, exhaust fan, methane transducer, time controller, alarm, power supply, electric wire and blast pipe, the manhole cover body are hollow
Structure, including the capping of upper cover plate, lower cover, well lid side wall and well lid, the upper cover plate middle part are provided with well lid capping hole, described
Well lid capping is installed in well lid capping hole, and the lower cover is provided with exhaust fan mounting hole, and the exhaust fan mounting hole site in
Well lid capping hole lower section, the exhaust fan mounting hole covers hole less than well lid, and the exhaust fan is installed on the exhaust fan and installs
Kong Zhong, is provided with methane transducer mounting hole by the exhaust fan mounting hole, the methane transducer is installed on methane transducer peace
In dress hole, the manhole cover body is additionally provided with drainpipe, and the drainpipe runs through the upper cover plate and lower cover, well lid side wall
Top is provided with steam vent, and the blast pipe connects the steam vent, and the electric wire passes through the steam vent and the blast pipe, institute
State time controller and the alarm is placed in outside the manhole cover body, time controller described in the power electric connection, institute
State time controller and be electrically connected the exhaust fan, the methane transducer and the alarm.
Used as a kind of improved mode, the well lid closure threads connect the upper cover plate, and the well lid capping is provided with two
Individual well lid covers open hole, and two well lid capping open holes are symmetrical relative to the central axis that the well lid is covered, described
Well lid capping open hole is blind hole, and a kind of automatic exhaust well cover for sewer also includes a well lid capping opening handle, institute
State well lid capping opening handle to be made up of a cross bar and two montants, two montants are respectively fixedly connected with the cross bar,
Two montants are in the same side of the cross bar, and two montants are parallel to each other, two montant central axis
Spacing is equal to the spacing that axially bored line is opened in two well lid cappings.
Used as a kind of improved mode, the exhaust fan is fanned for Water-proof exhausting.
Used as a kind of improved mode, the lower cover is provided with a step, the row at the exhaust fan mounting hole
Gas fan frame is fixed on the step, and less than the lower cover upper surface.
Used as a kind of improved mode, the well lid side wall at the steam vent is provided with an outside boss.
Used as a kind of improved mode, the lower cover is provided with a boss, and the methane transducer mounting hole site is in institute
Boss middle part is stated, the methane transducer bolt is anchored on the boss, and the methane transducer is water-proof sensor.
Due to taking above-mentioned technical proposal, having the beneficial effect that acquired by the present invention：
A kind of automatic exhaust well cover for sewer, controls exhaust fan to enter the biogas in well cover for sewer by time controller
Row regular discharge, reduces the biogas concentration in well cover for sewer, prevents biogas from gathering.And methane transducer is additionally provided with, can be examined
The biogas concentration surveyed in well cover for sewer, when biogas concentration reaches setting value, while time controller can connect exhaust fan pair
Biogas in well lid is discharged, after time controller connects exhaust fan certain hour, the biogas concentration in well cover for sewer
Also fail to drop to when under setting value, controller will connect alarm, alarm sends alert notification sewer maintenance personnel,
Attendant comes to check to be the problems such as draining is broken or steam vent is stifled by being connected to after alarm, and solves rapidly.
Because well lid closure threads connect upper cover plate, well lid capping is provided with two well lid capping open holes, two well lid envelopes
Lid open hole is symmetrical relative to the central axis that well lid is covered, and well lid capping open hole is blind hole, a kind of automatic exhaust sewer
Well lid also includes a well lid capping opening handle, and well lid capping opening handle is made up of a cross bar and two montants, two
Montant is respectively fixedly connected with cross bar, and two montants are in the same side of cross bar, and two montants are parallel to each other, two montant central shafts
The spacing of line is equal to the spacing that axially bored line is opened in two well lid cappings, and well lid covers concordant upper cover plate, and upper surface need not set
Handle, the cross bar of well lid capping opening handle is more long, and the strength needed for opening and tightening well lid capping is just smaller.
Due to exhaust fan for Water-proof exhausting is fanned, if the water that well cover for sewer inner chamber enters in water or sewer diffuses
Come, also do not interfere with the function of exhaust fan.
Because lower cover is provided with a step at exhaust fan mounting hole, exhaust fan frame is fixed on step, and is less than down
Cover plate upper surface, when there is leak to enter in well cover for sewer chamber above, can flow into sewer from exhaust fan mounting hole.
Because the well lid side wall at steam vent is provided with an outside boss, can be used to do determining when well cover for sewer is installed
Site, prevents steam vent from being docked with blast pipe incorrect.
Because lower cover is provided with a boss, methane transducer mounting hole site is in boss middle part, methane transducer bolt
It is anchored on boss, and methane transducer is water-proof sensor, methane transducer is anchored on boss, higher than lower cover upper table
Face, has prevented debris to be piled up at methane transducer, influences the sensitivity of methane transducer.
