Anti-washaway self-locking manhole cover structure

Abstract

The invention provides an anti-washaway self-locking manhole cover structure and discloses a manhole cover structure which is locked through supporting rods cooperating with upwelling accumulated water to fix a manhole cover body and is prevented from being washed away by water. The anti-washaway self-locking manhole cover structure is characterized in that a limiting cap is in screwed connectionwith one end of a sliding bar; one ends of a plurality of supporting rods are arranged on the outer wall of the limiting cap at equal angle; the other ends of the supporting rods obliquely extend upwards; a plurality of supporting feet are hinged to the other ends of the supporting rods in a one-to-one correspondence mode; the surface of each supporting foot is provided with a non-slip mat which is provided with non-slip protrusions; the middle section of each supporting rod is provided with a supporting sliding sleeve; a supporting frame is located above the limiting cap and penetrates through the supporting sliding sleeves of the supporting rods; the supporting frame is of a ring structure; the position, corresponding to the supporting sliding sleeves, of the supporting frame are provided with ring slots; the supporting sliding sleeves are located in the ring slots; one ends of a plurality of connecting rods are arranged on the supporting frame at equal angle; and the connecting rodsare located between every two adjacent supporting rods.

Description

technical field [0001] The invention relates to a self-locking manhole cover structure for preventing washing out and relates to a manhole cover structure capable of self-locking the manhole cover to prevent washing out, and belongs to the field of municipal engineering. In particular, it relates to a structure of a manhole cover that locks a device by cooperating with upwelling water through a support rod, thereby fixing the main body of the manhole cover and avoiding being washed away by water flow. Background technique [0002] At present, in the rainy weather, the drainage load of municipal drainage pipes is large and the drainage is not timely, which causes the sewage and rainwater in the inspection well mouth to pour upwards and push the inspection well cover on it, exposing the inspection well mouth, causing pedestrians and vehicles to fall into it by mistake , endangering the life safety of personnel, the notification number CN207331762U discloses a kind of waterproo...

[0002] At present, in the rainy weather, the drainage load of municipal drainage pipes is large and the drainage is not timely, which causes the sewage and rainwater in the inspection well mouth to pour upwards and push the inspection well cover on it, exposing the inspection well mouth, causing pedestrians and vehicles to fall into it by mistake , endangering the life safety of personnel, the notification number CN207331762U discloses a kind of waterproof flow impact inspection shaft cover, including the inspection shaft body, the inside of the inspection shaft body is fixedly connected with a support ring, the top of the inspection shaft body is provided with the inspection shaft cover body, the The front end and the rear end of the top of the manhole cover body are provided with outlet holes, and the bottom of the manhole cover body is fixedly connected with a fixed box, and the bottom of the fixed box extends to the inside of the manhole body to contact with the top of the support ring. There is a motor at the bottom of the inner wall of the box. The installation, disassembly and maintenance of this device is complicated. The motor drive design increases the operating cost, and the repair work after damage is also cumbersome.
