Description

Technical Field

[0001] The utility model relates to the technical field of water channel manhole covers, and particularly relates to a self-draining device for rainwater grates to intercept dirt, prevent odor and prevent falling. Background Art

[0002] Grille screens are often used on the water channels on the road to cover the water channel openings, which will not affect the walking of pedestrians or the driving of vehicles on the road. Generally, the environment in the sewer is harsh, and the odor or mosquitoes emitted affect the city appearance and environment.

[0003] At present, anti-odor manhole covers have been used in the market. However, the current anti-odor manhole covers adopt spring-type closing and offset anti-mosquito and anti-odor methods, which cannot achieve the real purpose. In addition, the current anti-odor manhole covers cannot achieve the effect of preventing falling. When the grille is installed out of position, there is a risk of people falling or vehicles getting stuck, causing certain casualties or property losses.

[0004] Chinese Patent CN201921897520.1 discloses an anti-odor sewer manhole cover, which has good sealing and anti-odor effects. However, when the shelter above it is inclined and cannot effectively bear people or vehicles, it is easy to cause casualties or property losses.

[0005] Therefore, how to provide a self-draining device for rainwater grates that can prevent falling and odor is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0006] In view of this, the utility model provides a self-draining device for rainwater grates to intercept dirt, prevent odor and prevent falling, which has the effect of preventing odor and also has the effect of preventing falling, and is safer to use.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme: A self-draining device for rainwater grates to intercept dirt, prevent odor and prevent falling, which comprises:

[0008] A trough body, which is used to cover the sewer wellhead. One end of the trough body is provided with a notch, and vertical sliding grooves are arranged on the inner side groove walls of the trough body near the notch.

[0009] A water passing valve plate, the top end of which is hinged to the trough body, and the water passing valve plate is used to control the opening and closing of the notch.

[0010] An intercepting net plate, which is slidably connected in the sliding groove and is used to intercept impurities in the water passing through the notch.

[0011] A covering grille, which is arranged at the notch of the trough body, and the intercepting size of the holes of the covering grille is larger than that of the intercepting net plate.

[0012] The beneficial effects of the present utility model are as follows: The water passing valve plate is hingedly connected to one side of the trough body and is used to control the opening and closing of the notch to achieve drainage. When the water flow in the trough body is sufficient to wash open the water passing valve plate, the water is drained through the notch. When there is no water or the water is very small, the water passing valve plate closes the notch, preventing the odor in the sewer from overflowing and also preventing mosquitoes from flying out. The interception net plate can intercept impurities or garbage entering the sewer again, reducing the risk of blockage of the entire sewer system. At the same time, the bottom wall of the trough body can prevent falling, avoiding casualties caused by the accidental tilt or breakage of the covering grate.

[0013] Preferably, a lapping surface is inclinedly provided at the edge end of the trough body corresponding to the notch, a continuous strip-shaped close contact layer is provided on the water passing valve plate corresponding to the lapping surface, and the water passing valve plate is inclinedly arranged in a static state.

[0014] The resulting technical effect is that the lapping surface provided at the edge end of the trough body corresponding to the notch is for better close contact with the water passing valve plate, so that the water passing valve plate can seal the notch under its own gravity, improving the anti-odor effect.

[0015] Preferably, a hinge for connecting with the trough body is provided at the top of the water passing valve plate, and the hinge is located outside the trough body.

[0016] The resulting technical effect is that the water passing valve plate can be movably connected to the trough body through the hinge and used to control the opening and closing state of the notch. It can be understood that the process of the water passing valve plate controlling the opening and closing state of the notch is a self-controlled process, which is self-controlled according to the amount of rainwater. Since the hinge is located outside the trough body, the rainwater will not corrode the hinge, thereby ensuring the service life of the components. The water passing valve plate can be made of stainless steel or alloy, etc.

[0017] Preferably, a torsion spring is connected to the connecting shaft of the hinge, and both ends of the torsion spring are respectively connected to both sides of the hinge and tend to open the hinge, and the torsion spring increases the sealing property between the water passing valve plate and the notch.

[0018] The resulting technical effect is that by installing the torsion spring, the close contact effect between the water passing valve plate and the trough body can be ensured.

[0019] Preferably, the trough body is formed by stamping, and the notch at one end of the trough body is processed by a cutting tool.

[0020] The resulting technical effect is that compared with the traditional welding forming, the stamping forming method has lower cost, higher production efficiency and is convenient for mass production. BRIEF DESCRIPTION OF THE DRAWINGS
