Water grate that is not easy to clog

Abstract

The invention discloses a water grate difficult to block. The water grate comprises a mounting plate and a drainage structure, wherein the drainage structure comprises drainage grooves, notches of thedrainage grooves are arranged upwards, a first siphon cavity section is formed between the outer side walls of the two adjacent drainage grooves, drainage holes are formed in the inner side wall surfaces of the drainage grooves in a penetrating manner, the upper end face of the mounting plate is provided with water passing openings corresponding to the notches, the two inner side walls of the water passing openings are arranged inwards to protrude out of the inner side walls of the drainage grooves, the inner side wall of the at least one water passing opening is folded downwards to form a folding arm, the folding arm extends into the drainage grooves and forms a second siphon cavity section which communicates with the drainage grooves with the inner side walls of the corresponding drainage grooves, the second siphon cavity section communicates with the first siphon cavity section through the drainage holes, and water collected above the water grate enters the drainage grooves throughthe water passing openings and is discharged into a sewer through the second siphon cavity section, the drainage holes and the first siphon cavity section, so that the stress of the sundries is reduced, the risk of blockage caused by the impurities adsorbed on the water grate is reduced, and the effect is good.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a water grate that is not easily blocked. Background technique [0002] In urban construction and management, the problem of rainwater discharge will be involved. The waterlogging problem caused by rainwater discharge is often reported in the newspapers. Under normal weather conditions, there are two main reasons for waterlogging: one is insufficient drainage caused by the blockage of the drainage pipe network. This kind of situation generally involves a relatively large area, and the impact caused by it is relatively large; another reason may be caused by the blockage of the drainage grate, which may be more common, especially during heavy rain or heavy rain at night Affected by the water flow and buoyancy, the sundries will accumulate more and more on the water grate, which will eventually cause the water grate to be blocked, the drainage will not be smooth, or even blocked an...

[0002] In urban construction and management, the problem of rainwater discharge will be involved. The waterlogging problem caused by rainwater discharge is often reported in the newspapers. Under normal weather conditions, there are two main reasons for waterlogging: one is insufficient drainage caused by the blockage of the drainage pipe network. This kind of situation generally involves a relatively large area, and the impact caused by it is relatively large; another reason may be caused by the blockage of the drainage grate, which may be more common, especially during heavy rain or heavy rain at night Affected by the water flow and buoyancy, the sundries will accumulate more and more on the water grate, which will eventually cause the water grate to be blocked, the drainage will not be smooth, or even blocked and the drainage will not be able to be drained. This situation will also cause unexpected losses and cause relatively large Impact

[0003] Each of the existing technologies has advantages and disadvantages. Some drainage mechanisms are too complicated, and some are difficult to manufacture or implement, and the cost is relatively high. The more critical problem is that these existing technologies have not fundamentally solved the grate blockage problem, because The clogging of the grate is mainly due to the fact that the grate is up and down, that is, the water level difference between the water on the ground or the road surface and the drainage pipe network, culvert box or pipeline is large, and the water flow speed is too fast, which leads to excessive force on the sundries and is directly absorbed by the water. Alluvial on the water grate, or being pressed by the water flow on the water grate, the sundries are sucked or attached to the water grate, and there is no chance to float up from the water, which often causes the water grate to be blocked or even blocked , therefore, it is necessary to optimize the structure of the water grate to reduce the occurrence of clogging of the water grate
