Sewer manhole cover with self-cleaning function

Abstract

The invention relates to a sewer manhole cover with a self-cleaning function and discloses a sewer manhole cover of which a conveyor belt can be rotated by treading a cover plate so as to push garbageon the sewer manhole cover into a waste storage box. The sewer manhole cover is characterized in that two support plates are arranged in a manhole cover fixing frame in parallel; the two support plates are adjacent to the two opposite side walls of the manhole cover fixing frame correspondingly; limiting blocks are arranged under the two ends of the support plates correspondingly; the limiting blocks are connected with the inner walls of the manhole cover fixing frame; the two ends of the support plates are arranged on the limiting blocks in a lap-joint mode; a plurality of buffer springs arearranged on the support plates at equal intervals; the manhole cover is arranged at the top end of the manhole cover fixing frame; the bottom of the manhole cover and the buffer springs on the two support plates are connected; a plurality of drain tanks are formed in a cover plate at equal intervals; two drive rollers are arranged in the manhole cover fixing frame in parallel and are adjacent tothe two ends of the manhole cover fixing frame correspondingly; and the two ends of the drive rollers are rotationally connected with the two inner side walls of the manhole cover fixing frame throughbearings correspondingly.

Description

technical field [0001] The invention relates to a sewer manhole cover with a self-cleaning function, relates to a sewer square manhole cover capable of automatic cleaning, and belongs to the field of municipal engineering. In particular, it relates to a sewer manhole cover which can rotate a conveyer belt and push garbage on it into a waste storage box for cleaning by stepping on a cover plate. Background technique [0002] Square sewer manhole covers can also be called cast iron grates, which are used to cover roads or deep wells at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Most of today's sewer manhole covers are straight-through Only the larger garbage can be blocked, while some small garbage such as fallen leaves and branches will pass through the manhole cover and flow into the sewer. The long-term accumulation of...

[0002] Square sewer manhole covers can also be called cast iron grates, which are used to cover roads or deep wells at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Most of today's sewer manhole covers are straight-through Only the larger garbage can be blocked, while some small garbage such as fallen leaves and branches will pass through the manhole cover and flow into the sewer. The long-term accumulation of these small garbage will easily cause the blockage of the sewer, requiring staff to carry out Timely dredging, resulting in a large workload of staff

[0003] Notification number CN206829190U discloses a kind of anti-theft and easy-to-clean well cover, including a well cover and a base; The hydrophobic holes are evenly arranged in the shape of a racetrack, the anti-slip holes adopt circular concave holes, the anti-theft structure adopts connecting bosses, the base includes a mounting structure, a connecting arrangement structure and a hydrophobic structure, and the mounting structure is located on three extension sides of the base. Installing holes are set, and the connection placement structure is arranged on the upper edge of the hydrophobic structure. The hydrophobic structure is provided with a hydrophobic hole on the side without the installation structure, and a grid-like cleaning net is arranged on the inside of the hydrophobic hole close to the hydrophobic structure; the device can only Larger volume of garbage is blocked, and small volume of garbage cannot be effectively cleaned

[0004] Notification number CN206267282U discloses a sewer wellhead cover plate, which includes a square manhole cover body, a number of water leakage holes are provided on the manhole cover body, support lugs are arranged at both ends of the bottom surface of the well cover body, a rotating shaft is arranged between the supporting lugs, and a plug is installed on the rotating shaft. When there is no external force, the sealing plate is in a horizontal state, thereby separating the inner cavity of the drainage ditch from the outside world. When the road surface water drips on the sealing plate through the leakage hole, the sealing plate tilts, and the drainage ditch The inner cavity is connected with the outside world, and the accumulated water flows into the drainage ditch. A layer of glass with a thickness of 4mm and a height of 7mm is installed in the reinforcement ribs formed between several horizontal leak holes and several vertical leak holes. Fiber, the blocking plate of the device is easy to stick and accumulate small garbage such as fallen leaves, which will cause the blockage of the whole well cover and affect the normal drainage
