Description

Municipal administration launching gear

Technical Field

The invention relates to a municipal drainage device.

Background

The sewer is an important facility for discharging urban road surface accumulated water, the well mouth position of the sewer is sealed by the inspection well cover, however, when water in the sewer is flooded, the inspection well cover positioned at the well mouth position is flushed away after being jacked up by water, so that the inspection well cover does not have a cover, and the position of the sewer can not be observed due to the accumulated water, so that people can often fall into the sewer, and the sewer is very dangerous.

The existing treatment method is to reform transform the sewer well, and the hole is drilled on the well wall of the sewer well, then the expansion bolt is driven in, and the safety net is assembled through the expansion bolt.

Therefore, the municipal launching device capable of effectively preventing personnel from falling into the well and blocking garbage is designed.

Disclosure of Invention

The invention aims to solve the technical problem of providing a municipal drainage device which can effectively prevent personnel from falling into a well and can intercept garbage.

In order to solve the problems, the invention adopts the following technical scheme:

the utility model provides a municipal administration launching gear, includes annular outer frame, form peripheral plate after the top casting of outer frame, when the construction, peripheral plate is pour in subaerial, and is not higher than ground the inside of outer frame is provided with a detachable safety net, the middle part of safety net is recessed form the ladder face after the inboard casting of outer frame, has supported the well lid through this ladder face, the middle part position department of well lid is provided with down the water hole, and the water hole corresponds the safety net, in rainy day, from mixture such as rainwater, rubbish that down water hole department got into fall into to the safety net, the rainwater passes the safety net, and rubbish is intercepted through the safety net.

Preferably, a threaded hole is formed in the bottom axis of the well lid, the diameter of the threaded hole is larger than that of the water outlet hole, a filter bowl is matched with the threaded hole, water outlet holes are uniformly distributed in the outer wall of the filter bowl, an overflow hole is formed in the position, close to the top, of the outer wall of the filter bowl, and when the water outlet hole is blocked or the water discharge amount is large, the water level in the filter bowl rises and is drained from the overflow hole in an emergency mode; the threaded holes are arranged at the bottoms of the water outlet holes and are coaxial, so that the assembled filter bowl can be prevented from being disassembled from the outside, and the anti-theft property of the filter bowl is improved; secondly, the filter bowl can block the sewer hole, so that the sewer hole cannot directly correspond to the safety net, and the safety net is prevented from being damaged by people maliciously from the sewer hole. The setting of filter bowl can also intercept rubbish, and the degree of depth of safety net is darker, therefore inconvenient cleanness under the condition of not opening the well lid, and the degree of depth of filter bowl is lighter, can follow the top of well lid through the pliers and clean, therefore the setting of filter bowl has still made things convenient for the operation of decontaminating.

Preferably, a plurality of grooves are annularly formed in the top of the well cover, radially penetrate through the well cover and are communicated with the water drainage hole, and the depth of each groove gradually increases towards the direction of the water drainage hole; the setting of recess can be with the water guide in the well lid outside to launching downthehole, increases the offal effect.

Preferably, a plurality of annular conduction grooves are coaxially arranged at the top of the well lid, and the grooves are conducted by the plurality of conduction grooves; the grooves are possibly blocked by sundries, and the conducting grooves can be communicated with a plurality of grooves, so that effective drainage is realized.

Preferably, an annular clamping groove is formed in the outer wall of the well lid, a sealing ring is clamped through the clamping groove, and the sealing ring is in contact with the inner wall of the outer frame; above-mentioned structure is in order to improve the tight degree of assembly in the well lid outside, reduces the noise that the vehicle caused when rolling.

Preferably, a plurality of bolts are annularly arranged on the stepped surface; an inner frame is supported on the step surface, the inner frame is hollow, a plurality of through holes corresponding to the bolts are annularly arranged on the inner wall of the inner frame, the bolts penetrate through the inner frame upwards and are matched with nuts, the bolts are supported at the bottom of the well cover, a connecting rod is matched through the through holes, a through groove is formed in the outer wall of the connecting rod, the bolts penetrate through the through groove, a counter bore is formed in one end, away from the axis of the outer frame, of the through groove, a spring is welded in the counter bore, and the spring contacts with the bolts; the end of the connecting rod, which is far away from the inner frame, is provided with a first nut, a steel cable is wound and fixed on the connecting rod, and the end of the steel cable, which is far away from the connecting rod, is provided with a steel ring; a plurality of hanging rings are fixed at the edge of the safety net, each hanging ring is provided with an opening, and the steel ring is assembled into the hanging ring through the opening.
