Problems solved by technology

However, under severe weather conditions such as heavy rain or heavy rain, due to the large surface runoff, a large amount of sundries are carried in the runoff, including plastic bags, vegetation, newspapers and other wastes, which are easy to attach to the surface of the flat grate gully. As a result, it will hinder its ability to pass water, and may even completely block the water hole of the rainwater outlet, resulting in poor water flow in the area around the rainwater outlet, seriously affecting its normal use
In addition, the commonly used vertical grate type gullies, etc., are similar in structure to the flat grate type gullies, and the above-mentioned problems also exist to varying degrees in use.

Embodiment 1

[0029] The present invention mainly achieves the design purpose by improving the original gully components and adding water and ventilation pipes, including an improved planar rectangular gully and a water and ventilation pipe connected to the surface of the gully. The improved planar rectangular rainwater grate has a circular hole, and 5-20cm is raised around the circular hole, which is made into a threaded sleeve form. The water and ventilation pipe with internal thread can be quickly connected to the circular hole. At each level, there are 4 rectangular holes on the pipe, and the rectangular holes are repeatedly set along the pipe height direction as required. These Rectangular holes can realize water flow and ventilation at the same time; the top of the water flow and ventilation pipe is open, which can further strengthen its air suction capacity, thereby improving the water flow capacity; the holes on the surface of the pipe can not only realize the function of water disch...

Embodiment 2

[0032] The anti-clogging gully device of the present invention is mainly made up of two parts, rainwater grate 1 and pipeline section 3, and the center of rainwater grate 1 is provided with circular hole, and other parts also have hole. The surrounding wall of the pipeline section 3 is provided with a drain hole, and the lower section of the pipeline section 3 is provided with an internal thread; the circular hole of the rainwater grate is provided with a threaded sleeve upwards, and the threaded sleeve is provided with an external thread, and the pipeline 3 is set outside the threaded sleeve. , the two are connected by threads. Branches 5 are arranged around each rectangular weep hole 4, and the branches 5 are scattered around the water outlet in a ring shape.

[0033] Among them, the rectangular drain hole 4 and the branches 5 on the pipeline section 3 should be processed in advance, and the branches 5 can be directly fixed on the surface of the pipeline section 3 by means o...

Abstract

The invention provides an anti-clogging gutter inlet device of a novel three-dimensional mechanism. The anti-clogging gutter inlet device solves the technical problem that the existing gutter inlet is poor in discharging capacity and easy to clog, can effectively reduce clogging of the gutter inlet caused by impurities in runoff, and strengthens water passing capacity. The anti-clogging gutter inlet device comprises a rainwater perforaled strainer and a pipe section, wherein the lower end of the pipe section is connected with the front surface of the rainwater perforaled strainer, a plurality of discharging holes are formed in the peripheral wall of the pipe section, and a plurality of branch-shaped objects are arranged around the discharging holes. The anti-clogging gutter inlet device has the advantages of effectively preventing particulate matters and waste carried in the runoff from clogging the gutter inlet, improving discharging capacity, quickly discharging impounded surface water caused by high-flow surface runoff such as intense fall and being simple in structure. Furthermore, members used by the anti-clogging gutter inlet device are manufactured easily and installed conveniently and quickly.

Description

Technical field: [0001] In order to solve the ground water caused by heavy rainfall, etc., the present invention relates to a threaded anti-clogging gully, specifically an anti-clogging gully device, which belongs to the technical field of rain / sewage discharge. Background technique: [0002] In recent years, with the acceleration of urbanization, urban waterlogging caused by rainfall has become one of the main disasters that threaten the lives and property safety of urban and rural residents. Trapped in low-lying areas and drowned. This puts forward an urgent requirement to improve the drainage facilities of the existing cities. As one of the basic components of urban drainage facilities, gullies are the entrance for road surface water to drain into urban and rural drainage facilities. Its performance directly affects the normal operation of drainage facilities. [0003] At present, the surface of the usual flat grate gully is rectangular, and the water flow capacity ca...
