Description

Inspection well cover

Technical Field

The invention relates to the field of municipal engineering, in particular to an inspection well cover.

Background

The manhole cover is seen everywhere in urban roads as an important component in municipal drainage systems, and is laid on and level with the road surface provided with a sewer. The well cover has the main function of collecting rainwater accumulated on the road surface into a sewer, so that the road surface is kept dry, and the problem of skidding of the road surface caused by excessive accumulated water is avoided; another function is to act as an inlet for the sewer node, so that there is an easy access for the cleaning operation to be carried out at various locations in the sewer.

For the safety of pedestrians, the drain holes of the well cover cannot be too large, but another problem is also brought, namely that the drainage is poor, water is easy to accumulate on the road surface in heavy rain weather, and the water is difficult to discharge to a sewer in time, but if the drain holes are too large, the feet of vehicle tires and pedestrians are easily clamped in, so that the safety problem is caused;

if the drain hole is made small, the whole well cover is easily sealed due to the blockage of solid matters in rainwater, and water cannot be drained into a sewer.

In addition, when the rainfall is very big, the rainfall in the sewer is very big, because the velocity of flow is slow, leads to drainage efficiency to reduce, and then often can appear the rainwater and gush out the condition of well head, leads to surface gathered water serious, if can carry out an extrusion with higher speed to the rainwater in the sewer to possess supplementary transition water storage function, so can effectively solve the problem that the rainwater gushed out the sewer.

Detailed Description

As shown in fig. 1 and 2, an inspection well cover comprises a well cover 5 installed in a well head, the well cover 5 comprises a base 501 and a movable plate 6, the base 501 is installed at the well head, the upper end surface of the base 501 is provided with a water inlet cavity 506 with a circular structure, the movable plate 6 is installed in the water inlet cavity 506, the bottom surface of the water inlet cavity 506 is provided with more than one main drainage hole 505 around the water inlet cavity, the bottom surface of the movable plate 6 facing each main drainage hole 505 is provided with a corresponding sealing block 503, the sealing block 503 passes through the main drainage hole 505 and extends out of the lower end surface of the base 501, the inner wall of the base 501 is provided with more than one auxiliary drainage hole 502 around the inner wall of the base, each auxiliary drainage hole 502 extends upwards towards the height direction, the outer wall of the movable plate facing each auxiliary drainage hole 502 is provided with a limiting piece 504, the limiting piece 504 passes through the auxiliary drainage holes 502, the lower, the bottom of the connecting rod 7 is provided with a floating body 3, the lower end surface of the floating body 3 is in contact with water in a sewer and floats upwards, and the connecting rod penetrates through the square through hole at the bottom of the base.

Wherein, the center of the upper end surface of the floating body 3 is provided with a connecting shaft sleeve 8, the bottom of the connecting rod 7 is inserted into an assembly hole of the connecting shaft sleeve 8 and is welded and fixed, and the section of the connecting rod 7 is square.

As shown in fig. 3, the lower end surface of the floating body 3 is an inclined surface, which is convex 301 on the side where the water flows and concave 302 on the side away from the water flow. Because the structure that sets up the body is the slope structure, consequently when the body descends the extrusion, can apply an inclined extrusion force towards the bottom, and then promote the water in the sewer and remove towards the place ahead, increase the velocity of water flow, and then increase drainage efficiency.

The movable plate 6 is circular, the outer diameter of the movable plate is smaller than the inner diameter of the water inlet cavity 506, and a clearance cavity 111 for water inlet is formed between the outer wall of the movable plate and the inner wall of the water inlet cavity. When normally raining, the rainwater can enter into the clearance intracavity, the water level in sewer 4 is not very high this moment, the fly leaf can push down main wash port, the vice wash port through the outside carries out the drainage, and when the rainfall increases, 4 inside water levels of sewer are when very high, the body can follow the water level and rise, and then the fly leaf of slow jack-up connecting rod and connecting rod upper end for sealed piece is extracted from main wash port, can utilize main wash port to carry out the drainage this moment, increase displacement.

In this embodiment, the floating body 3 is made of buoyancy foam material, and the outer wall of the floating body is wrapped with a layer of anticorrosive coating. The volume of the floating body 3 can be relatively larger, the area during extrusion is increased, the buoyancy is increased, and the movable plate at the upper end can be jacked up.

In this embodiment, more than one mounting hole is seted up to the inner wall both sides of sewer 4, all packs into one in every mounting hole and lets pipe 2, and the inside of letting the pipe has one and lets the chamber, the outside end of letting the pipe is provided with one section bending 1, and bending 1 extends towards the upper end direction slope. When the body extrudees, rivers can be incessantly gushed for during the rivers that gush enter into the pipe of giving up, get into the back, the water yield in the sewer can the certain degree decline a little, slows down drainage pressure.

Because the fly leaf floats after the body jack-up, if the vehicle passes through well lid upper end this moment, the weight of vehicle can push down the fly leaf for the fly leaf descends, and the body descends, and the spacing piece that the fly leaf drove the outer wall descends along vice wash port this moment, gets rid of the accumulational jam in the vice wash port, and the effect of spacing piece also is used for the spacing that rises to the fly leaf simultaneously, and the sealing piece that descends also can switch on main wash port, prevents that debris from blockking up. The vehicle travels through the upper end of the movable plate, so that the floating body descends, and after the vehicle passes through the upper end of the movable plate, the floating body returns to the original position, so that the floating movement is realized, and the water flow velocity is increased.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
