Problems solved by technology

[0003] Based on the discovery of the inventors above, the existing manhole cover for municipal engineering mainly has the following deficiencies, such as: when it rains, the plastic bag on the road will follow the rainwater to flow into the manhole cover, and there is water in the plastic bag It will be attached to the through holes on both sides of the drainage tank, and it will not easily flow into the drainage tank, causing the plastic bag to be attached to the port of the drainage tank and causing blockage, causing rainwater to accumulate on the road and form puddles

Embodiment 1

[0026] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiment of the present invention is as follows: its structure includes a fixing seat 1, a fixing hole 2, a manhole cover 3, the side end of the fixing seat 1 is provided with more than ten fixing holes 2, and the fixing holes 2 surround the fixing seat 1. The side ends are arranged. The manhole cover 3 is located at the upper end of the fixed base 1 and is engaged with the fixed base 1. The manhole cover 3 includes a movable shaft 31, a drainage groove 32, a through hole 33, a clamping block 34, and a stirring block 35. The movable shaft 31 is located at the bottom side end of the manhole cover 3 , there are two drainage grooves 32 located in the middle of the manhole cover 3 , and there are two through holes 33 located in the middle of the two drainage grooves 32 . Position, the engaging blocks 34 are provided with two, and are embedded and fixed directly below the through holes 33 , and the stirring block...

Embodiment 2

[0031] Example 2: Please refer to Figure 6-Figure 8 , the specific embodiment of the present invention is as follows: the baffle plate 353 includes a plate body b1, a water flow groove b2, a card groove b3, a water blocking plate b4, and a rewind spring b5, and a water flow groove b2 is provided in the middle of the plate body b1, The water flow groove b2 is rectangular in shape, the card groove b3 is arranged at one end of the water flow groove b2, and the other end is engaged with a water blocking plate b4, and two rewind springs b5 are provided, which are respectively nested in the blocking plate. On both sides of the water plate b4, the water blocking plate b4 is engaged with the card slot b3, which is conducive to the reset of the rewinding spring b5 to drive the water blocking plate b4 to be engaged in the card groove b3, so that the connecting rod 351 can only perform one-way movement. rotate.

[0032] The water blocking plate b4 includes a water blocking body b41, a ...

Abstract

The invention discloses a well cover for municipal engineering. The structure includes a fixed seat, a fixing hole, and a well cover. The well cover includes a movable shaft, a drainage groove, a through hole, an engaging block, and a stirring block. Baffle plate, rolling block, rolling block includes main column, outer roller body, fixed rod, return spring, telescopic block, telescopic block includes telescopic body, support seat, rubber pad, groove, the present invention hits baffle plate by rainwater, makes The baffle drives the connecting rod to rotate, so that the rolling block embedded in the middle of the connecting rod also rotates. The rubber material of the telescopic block can increase the friction when the telescopic block is in contact with the plastic bag. The grooves are horizontally arranged on the upper end of the rubber pad, so that the plastic bag can be absorbed in the groove, and the friction between the rubber pad and the plastic bag is increased, so that the plastic bag attached to the manhole cover is guided to the lower end of the manhole cover, and the plastic bag is avoided. Situations that cause blockages on manhole covers.

Description

technical field [0001] The invention relates to the field of municipal administration, in particular to a well cover for municipal engineering. Background technique [0002] Manhole covers 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. Piers, alleys, etc. [0003] Based on the above findings of the present inventors, the existing manhole cover for municipal engineering mainly has the following deficiencies, such as: when it rains, the plastic bags on the road will follow the rainwater to flow into the manhole cover, and there is water in the plastic bags. It will be attached to the through holes on both sides of the drainage groove, and it is not easy to flow into the drainage groove, which will cause the plastic bag to attach to the port of the drainage groove and cause blockage. ...
