Problems solved by technology

[0002] The sewer is an important facility for draining urban road surface water. The wellhead of the sewer is blocked by the inspection well cover. However, when the water in the sewer is flooded, the inspection well cover at the wellhead will be pushed up by the water and then flushed. If it is opened, there will be no cover on the inspection well cover, and due to the accumulation of water, the position of the sewer well cannot be observed, so it will often cause people to fall into the sewer, which is very dangerous
[0003] The existing treatment method is to transform the sewer well, which drills holes on the well wall of the sewer well, then drives in expansion bolts, and assembles the safety net through the expansion bolts. In the above structure, the function of the safety net is relatively simple

Embodiment 1

[0033] A municipal sewer device, comprising an annular outer frame 1, the top of the outer frame 1 is cast to form a peripheral plate 101, during construction, the peripheral plate 101 is poured in the ground, and is not higher than the ground, and the outer A detachable safety net 2 is arranged inside the frame 1, the middle part of the safety net 2 is concave, and a stepped surface 102 is formed after casting on the inner side of the outer frame 1, and a manhole cover 3 is supported by the stepped surface 102. The middle part of the well cover 3 is provided with a drain hole 301, which corresponds to the safety net 2. In rainy days, rainwater, garbage and other mixtures entering from the drain hole 301 fall into the safety net 2, and the rainwater passes through the safety net. 2. Garbage is intercepted through the safety net 2.

Embodiment 2

[0035]A threaded hole 302 is provided at the bottom axis of the well cover 3, and the aperture of the threaded hole 302 is larger than the aperture of the water hole 301, and a filter cup 4 is fitted through the threaded hole 302, and the filter cup 4 Water outlet holes 401 are evenly distributed on the outer wall, and overflow holes 402 are arranged near the top of the outer wall of the filter cup 4. When the water outlet holes 401 are blocked or the amount of water is large, the water level in the filter cup 4 rises from the overflow. Emergency drainage at the hole 402; the threaded hole 302 is set at the bottom of the water hole 301 and is coaxial, so the installed filter cup 4 can avoid being disassembled from the outside, which improves the anti-theft performance of the filter cup 4; secondly, the set The filter cup 4 can block the water hole 301, so that the water hole 301 cannot directly correspond to the safety net 2, so as to avoid someone maliciously destroying the sa...

Embodiment 3

[0037] A plurality of grooves 311 are annularly arranged on the top of the well cover 3, the grooves 311 radially penetrate the well cover 3, and communicate with the water hole 301, and the depth of the grooves 311 is toward the water hole The direction of 301 gradually increases; the setting of the groove 311 can guide the water outside the manhole cover 3 into the water hole 301, increasing the effect of water launching.

Abstract

The invention discloses a municipal drainage device. The municipal drainage device comprises an annular outer frame, a peripheral plate is formed after the top of the outer frame is cast, during construction, the peripheral plate is poured in the ground and is not higher than the ground, a detachable safety net is arranged in the outer frame, the middle of the safety net is concave downwards, the inner side of the outer frame is cast to form a step face, a well lid is supported through the step face, and a drainage hole is formed in the middle of the well lid and corresponds to the safety net; and in rainy days, mixtures such as rainwater and garbage entering from the drainage hole fall into the safety net, the rainwater penetrates through the safety net, and the garbage is intercepted by the safety net. The device can effectively prevent people from falling into the well, and can also intercept garbage.

Description

technical field [0001] The invention relates to a municipal sewage device. Background technique [0002] The sewer is an important facility for draining urban road surface water. The wellhead of the sewer is blocked by the inspection well cover. However, when the water in the sewer is flooded, the inspection well cover at the wellhead will be pushed up by the water and then flushed. If it is opened, there is no cover at the inspection well cover, and because of the accumulated water, the position of the sewer well cannot be observed, so it often causes people to fall into the sewer, which is very dangerous. [0003] The existing treatment method is to transform the sewer well, which drills a hole on the well wall of the sewer well, then drives in expansion bolts, and assembles a safety net through the expansion bolts. In the above structure, the function of the safety net is relatively single. [0004] To this end, we have designed a municipal sewer device that can effectiv...
