Description

An anti-clogging gutter device

Technical field:

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:

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.

At present, the surface of the usual flat grate gully is rectangular, and the water flow capacity can meet the requirements under normal use. 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. Thereby hindering 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 gullies, etc., are similar in structure to the flat grate gullies, and the above-mentioned problems also exist to varying degrees in use.

Invention content:

According to the above problems in the prior art, the present invention innovatively provides a novel anti-clogging gully device to reduce the blockage of the gully by sundries in the runoff and enhance its water flow capacity.

The purpose of the present invention is achieved through the following technical solutions:

An anti-clogging gutter device, the device includes a rainwater grate, and also includes a pipeline section, the lower end of the pipeline section is connected to the front of the rainwater grate, a number of drain holes are arranged on the peripheral wall of the pipeline section, and around the drain hole Install several branches.

Further detailed design of the present invention is:

The lower end of the pipeline section is provided with an internal thread; the front of the rainwater grate is provided with a threaded sleeve, which is connected to the lower end of the pipeline section, and a circular hole is also provided in the center of the rainwater grate.

The plane size of the rainwater grate is 84cm×64cm, and the height is 10cm; the height of the threaded sleeve is 5cm, and the diameter is 150mm.

The pipe section has a diameter of 150mm and a height of 50-200cm.

The drain hole of the pipeline section is a rectangular or elliptical drain hole, and the area of the rectangular or elliptical drain hole is 15-20 cm ² .

The branches are made of steel bars with a diameter of 6 mm and a length of 30 cm.

The rainwater grate is made of ductile iron, and the pipe section is made of PVC or PE material.

The anti-clogging rainwater outlet device itself is in a three-dimensional form, which can effectively reduce the poor water flow caused by the rainwater outlet being covered by sundries. For bridge openings, culverts and tunnels and other low-lying places that are prone to water accumulation, the device of the present invention can effectively strengthen rainwater drainage, help to reduce pedestrian casualties caused by water accumulation in low-lying places and vehicles due to engine water intake, etc. property damage event.

When there is a lot of debris in the runoff, branches such as steel bars can be installed vertically around each drain hole. These branches can prevent debris in the runoff from invading the rainwater outlet through the drain hole, thereby maintaining its normal drainage capacity , The number of branches can be set according to needs, ranging from 2mm-20mm in diameter.

Compared with the prior art, the present invention has the following advantages:

1) The present invention summarizes the drainage principles and methods of the existing gullies, and innovatively transforms the existing gullies, such as flat grate gullies and vertical grate gullies, from a two-dimensional planar drainage method into a three-dimensional three-dimensional way , which greatly improves the drainage capacity of the rainwater outlet, thereby quickly removing the ground water;

2) Large-flow surface runoff such as heavy rain is often accompanied by high content of impurities such as sediment, and also carries a large amount of plastic bags and vegetation and other wastes. After these impurities and wastes pour into the stormwater outlet, it is easy to cause the stormwater outlet to be congested or Clogged, resulting in the loss of drainage capacity of the gully. The branch parts in the present invention block the sundries mixed in the surface runoff at the periphery of the drain hole like an arm, so that the sundries can be prevented from directly entering the storm water outlet during the water discharge process, effectively maintaining the water flow capacity of the rain water outlet, and realizing Meet the anti-clogging needs of the rainwater outlet.

3) Surface runoff in urban and rural areas often lasts for a short time and has a large amount of rainfall. The drainage device is required to be easy and quick to install. The parts of the device of the present invention are connected by threads, which can be assembled and put into use in a short time, and have good applicability.

4) The installation of the present invention is simple and quick, and it is suitable for the situation that there will be heavy rainfall in the use area, and can meet the requirements of quick installation. A small amount of holes can be opened around the circular hole on the rainwater grate to increase the water flow capacity.

Detailed ways:

Embodiment one:

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 discharge, but also help Realize higher water flow capacity of gullies under ventilation conditions.

During use, the flat rectangular rainwater grate is fixed on the rainwater well, and then the water and ventilation pipe is connected with the screw thread on the rainwater grate. For areas with high rainfall, when used in the rainy season, the number of disassembly can be reduced according to the rainfall after installation to ensure smooth drainage around the use area. After the rain stops, the pipe can be quickly removed from the rainwater grate with pipe wrench and other tools as needed, which also reduces the damage to the pipe when it is placed outdoors for a long time.
