Description

Technical Field

[0001] The utility model belongs to the field of drainage pipes, and in particular relates to a water grate for preventing foreign matter. Background Art

[0002] A water grate is a device used to filter impurities and solid particles in water, usually used at the water inlet or outlet of a water pump or water pipe system. It acts like a filter, blocking larger impurities and solid particles and preventing them from entering the pipe or equipment, thereby protecting the equipment and improving water quality.

[0003] Water grates are usually made of metal or plastic meshes, and the mesh size can be different according to the needs. Generally, the size is slightly smaller than the water pump inlet or outlet to ensure that impurities can be effectively filtered out. They are widely used in various water systems, including household tap water systems, industrial water systems, agricultural irrigation systems, etc.

[0004] However, there are still many problems with the water grate during actual use. For example, in dusty usage scenarios, larger debris will be blocked by the mesh of the water grate, but dust-type dirt will flow through the mesh into the pipe below the water grate. Over time, the accumulated dust mixed with wastewater will form sludge that will block the drainage pipe, especially when the drainage pipe changes from vertical to horizontal. The sludge is difficult to be washed away by wastewater with a small flow rate. The sludge will reduce the space for the wastewater to flow, eventually causing the water discharge speed of the sewer pipe at the water grate to slow down until it is completely blocked.

[0005] Therefore, a new design of water grate is needed that can better adapt to the working environment with more dust. Utility Model Content

[0006] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a water grate for preventing foreign matter.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0008] A foreign body-proof water grate comprises an upper cover and a lower cover, wherein the upper cover is provided with meshes, a sewer pipe connection port is provided at the bottom of the lower cover, a cavity is provided between the upper cover and the lower cover, and a movable stopper is provided in the cavity.

[0009] The volume of the stopper is smaller than the size of the cavity, and the volume of the stopper is larger than the size of the water pipe connection port.

[0010] When the stopper moves to the edge of the cavity, the water pipe connection port can also be blocked.

[0011] The stopper is an air bag.

[0012] The upper cover and the lower cover are detachable structures.

[0013] The upper cover and the lower cover are fixed by bolts.

[0014] The upper cover and the lower cover are fixed by buckles.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model is mainly aimed at improving the water grate used in dusty environments. A block is added to the cavity between the water grate and the sewer pipe. The overall structure of the block is smaller than the size of the cavity between the water grate and the sewer pipe and has a density smaller than water. The width of the block can completely cover the drain port of the sewer pipe, and can prevent dust from entering the sewer pipe when no water flows in. When draining water, the block will float up due to its own density, and will not affect the normal drainage of the sewer pipe. The utility model can solve the problem that the water grate in dusty environments cannot block dust through a simple design, and has a simple structure and low modification cost.

[0021] The utility model is further described below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the structure of the utility model mainly includes an upper cover 1 and a lower cover 2 constituting a water grate and a stopper 3 placed between the upper cover 1 and the lower cover 2 .

[0023] The utility model is aimed at improving the common water grate in the prior art. The structure of the upper cover 1 is a baffle with a plurality of meshes, and the middle part of the lower cover 2 is provided with a through hole connected to the water outlet of the sewer pipe.

[0024] Compared with the traditional water grate, a cavity structure with a certain size can be formed between the upper cover 1 and the lower cover 2, and a stopper 3 is placed in the cavity structure.

[0025] The shape and size of the stopper 3 need to be determined according to the size of the cavity structure. The overall size of the stopper 3 is smaller than the size of the cavity structure, and the stopper 3 can move freely in the cavity structure without any additional limiting structure for the stopper 3. However, the size of the stopper 3 needs to be larger than the drain port of the sewer pipe, and when the stopper 3 moves to contact the edge of the cavity structure, the stopper 3 can still completely block the drain port.

[0026] In addition to the size of the block 3, the density of the block 3 is also limited. The density of the block 3 needs to be smaller than the density of water. When the water flows into the water grate, the block 3 needs to be able to float up under the influence of the water flow and will not affect the normal flow of water into the sewer pipe, so as to achieve automatic conduction of the water grate during drainage. Therefore, in this embodiment, the block 3 adopts an airbag structure.

[0027] The upper cover 1 and the lower cover 2 are detachable structures, such as bolt structures and buckle structures, which can be used between the upper cover 1 and the lower cover 2 of this solution. When a large amount of dust falls on the top of the water grate, part of the dust will accumulate on the top of the upper cover 1, and the other part of the dust will fall into the cavity between the upper cover 1 and the lower cover 2. At this time, cleaning the vicinity of the water grate in advance before flushing can greatly reduce the probability of the sewer pipe being blocked, and the detachable structure enables the staff to directly open the upper cover 1 to deal with the dust that falls into the cavity structure.

[0028] However, when flushing, it is inevitable that water-insoluble dust will still be brought into the water grate. The cavity structure and the block 3 will retain or adhere to a part of the dust in a silt state, and will not allow the dust to directly enter the sewer pipe. At this time, the staff can also directly open the upper cover 1 to clean the dust trapped in the cavity structure to reduce the blockage of the sewer pipe.
