Technical Field

[0001] The invention relates to the field of municipal construction, and in particular to an anti-clogging and environment-friendly manhole cover. Background Art

[0002] During daily use, the drainage holes of manhole covers are often blocked by fallen leaves or various garbage. The blockage of manhole covers causes poor drainage, which leads to urban waterlogging. When heavy rains come, a large number of workers are often required to dredge the manhole covers, which not only wastes a lot of manpower and material resources, but also fails to maintain the dredging effect.

[0003] In the prior art of an anti-clogging manhole cover proposed in publication number CN108532732A, it is specifically proposed that "it includes a manhole cover, a circular groove is provided at the upper end of the manhole cover, a drainage channel is provided around the circular groove, an arc-shaped elastic plate is provided at the upper end of the circular groove, a fixing rod is fixedly connected to the circular groove, a first spring and a sleeve are sleeved on the fixing rod, a pressing plate matching the circular groove is connected to the sleeve, a compressed air chamber is formed between the pressing plate and the circular groove, a control mechanism is provided in the exhaust channel, a plurality of air intake channels are provided at the bottom of the circular groove, and a first one-way valve is provided in the air intake channel."

[0004] In the prior art of a rotating anti-clogging manhole cover proposed with publication number CN109056828A, it is specifically proposed that "it includes a manhole cover body, an annular cavity is provided in the manhole cover body, the upper side wall of the annular cavity is provided with multiple water inlets, the lower side wall of the annular cavity is provided with a drain outlet, a rotating ring is rotatably connected to the inner side wall of the concave side of the annular cavity, a plurality of guide grooves are provided on the outer side wall of the rotating ring, a connecting rod is fixedly connected to the outer side wall of the rotating ring, a scraper is fixedly connected to the lower side wall of the connecting rod, a ventilation groove is provided at the upper end of the manhole cover body, and an elastic plate with a circular arc convex surface is fixedly connected at the groove of the ventilation groove."

[0005] The above-mentioned prior art also has the following defects: However, the inventors found that the dust on the road surface often dissolves into the water and enters the manhole cover, and the blockage is mostly caused by the fallen leaves of green plants on both sides of the road and some other garbage. For this reason, we proposed an anti-blockage and environmentally friendly manhole cover. Summary of the invention

[0033] Reference Figure 3 The track plate a7 is fixedly connected to the track plate b8 via a support frame a71, and the track plate b8 is fixedly connected to the inner wall of the frame 1 via a support frame b81. A plurality of track grooves 11 are distributed in the track plates a7 and b8.

[0034] It is worth mentioning here that the track plate a7 is fixedly set on the track plate b8, and the track plate b8 is fixedly connected to the frame 1 through the support frame b81 to provide support for the dredging component 9 and the cleaning component 10.

[0035] Reference Figure 4-6 The dredging component 9 includes a support rod a91 slidably set on the track groove 11, a support rod b93 slidably set on the track groove b92 on the inner wall of the frame 1, and a fixed block a94 fixedly set on the upper end of the support rod b93, and the size of the fixed block a94 matches the size of the water permeable hole 3.

[0036] In this embodiment, the fixing rod 5 is pressed downward to squeeze the support rod a91, and the support rod a91 squeezes the support rod b93 to lift the fixing block a94.

[0037] Reference Figure 4-6 The contact surfaces of the support rod a91 and the support rod b93 are both set to be 45-degree inclined planes, the cross-section of the other end of the support rod a91 gradually decreases, and the inclination of the inclined plane at the other end of the support rod a91 is consistent with the conical inclination of the lower end of the fixed rod 5.

[0038] It is worth mentioning here that the cross-section of the other end of the support rod a91 gradually decreases, thereby avoiding collision of the support rod a91 near the center of the fixing rod 5.

[0039] Reference Figure 7-9 The cleaning assembly 10 includes a support rod c101 arranged on the track plate b8, a support rod d103 slidably arranged on the through hole b102 between the water permeable holes 3, a fixed block b104 fixedly arranged on the upper end of the support rod d103, an inclined block 105 fixedly arranged on the lower end of the support rod d103, a column 106 arranged on the support rod d103, and a guide rail 107 for driving the column 106 to move.

[0040] In this embodiment, the fixing rod 5 is pressed down to squeeze the support rod c101, and the support rod c101 squeezes the support rod d103 to lift the fixing block b104. Under the action of the guide rail 107, the obstruction on the fixing block a94 is swept aside.

[0045] It is worth noting that by setting the fixing block b104 in the groove 31 and making the upper surface of the fixing block b104 highly consistent with the upper surface of the manhole cover 2, the flatness of the manhole cover surface can be ensured.

[0046] The working process is as follows:

[0047] When the car is driving, the arc-shaped protrusion 4 on the manhole cover 2 is squeezed, driving the fixing rod 5 to press down, and then squeezing the support rod a91, and the support rod a91 squeezes the support rod b93 to lift the fixing block a94; when the fixing rod 5 continues to press down, it squeezes the support rod c101, and the support rod c101 squeezes the support rod d103 to lift the fixing block b104; through the column 106 sliding on the guide rail 107, the fixing block b104 is driven to first rise and then rotate, sweeping the obstruction on the fixing block a94 to the side; through the reset spring 6, the fixing rod 5 is driven to reset.
