Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, and in particular to a vortex-effect anti-siltation rainwater grate structure. Background Technology

[0002] Storm drains are facilities in a pipe drainage system that collect surface water. They are typically installed in blocks, squares, and along streets as inlets for rainwater runoff to flow into the sewage system, preventing rainwater from flooding roads or causing water accumulation in low-lying areas, thus avoiding traffic obstruction or road damage. Storm drains are usually equipped with grates, which filter and trap debris in the water flow, while also preventing vehicles and pedestrians from falling into the drains. The most common type is the flat grate, which is usually installed on both sides of the road and needs to withstand the weight of vehicles. Traditional municipal grates are easily clogged by leaves and garbage, leading to reduced drainage efficiency and high manual cleaning costs. Existing technologies mostly rely on filters or interceptors, but these require frequent maintenance. Therefore, a solution is urgently needed.

[0003] The above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] Example

[0020] See Figure 1-2 As shown: This utility model provides a vortex effect anti-siltation rainwater grate structure, including: grate plate 10, flow guiding component and collection tank 30.

[0021] In practical use, the grate 10 is installed at the road's storm drain inlet. The grate 10 has an inlet, thus functioning as a manhole cover for the roadside storm drain. The flow guiding component and the collection bucket 30 are both located within the storm drain inlet, with one end of the flow guiding component connected to the grate 10 and the other end connected to the collection bucket 30. The flow guiding component receives the solid-liquid mixture flowing into the grate 10, separates the solid from the liquid, and directs the separated solid matter into the collection bucket 30. This method avoids the accumulation of the mixture and collects and treats the solid matter that causes blockage, resulting in smoother drainage and improved overall performance of the grate substructure.

[0022] The flow guiding component includes a funnel 20; the top of the funnel 20 is connected to the grate 10, and the bottom is connected to the inlet of the collection bucket 30. By setting the funnel 20, a vortex can be automatically formed after water enters the grate 10, thereby making the drainage smoother.

[0023] To improve the solid-liquid separation effect, a guide channel 21 is provided on the inner wall of the funnel 20; the guide channel 21 is arranged in a spiral shape from the top inlet to the bottom outlet of the funnel 20. In actual use, the guide channel 21 can guide the water flow to form a vortex, producing an adsorption effect, thereby directly sucking the object flowing into the grate 10 into the collection tank 30.

[0024] A nozzle 22 is provided in the guide channel 21; the nozzle 22 is located at the bottom end of the guide channel 21 near the funnel 20, and the outlet direction of the nozzle 22 is tangent to the outer wall of the funnel 20.

[0025] With this setup, not only can excess water in the guide channel 21 be discharged along the nozzle 22, but the water flow along the outlet direction of the nozzle 22 can also wash the outer wall of the funnel 20, thereby cleaning the mud and sand stuck to the bottom of the funnel 20.

[0026] The collection bucket 30 includes an inner bucket and an outer bucket; the top of the inner bucket is connected to the bottom of the funnel 20, and the inner bucket is fitted into the outer bucket. The surface of the inner bucket is provided with filter holes, which facilitates the water in the inner bucket to be discharged along the filter holes and leaves large-diameter solids inside the inner bucket. The surface of the outer bucket is provided with a drain window 31, which enables the water to be discharged quickly.

[0027] An annular overflow port is provided between the top of the inner barrel and the bottom of the funnel 20. When the water inside the inner barrel is difficult to flow out quickly, it can flow out along the annular overflow port to achieve the purpose of rapid drainage.

[0028] It also includes a filter cylinder 40; the top of the filter cylinder 40 is connected to the bottom of the funnel 20 and is fitted onto the outside of the outer barrel. This design intercepts solid matter flowing out along the annular overflow port, thereby improving the solid-liquid separation effect.

[0029] In practical use, the guide channel 21 is set as a constant pitch spiral structure (60mm pitch, 7° helix angle), with a channel depth of 20mm and a V-shaped flushing channel. The nozzle 22 is set at a 30° elevation angle (Φ2.5mm, spacing 15cm).

[0030] The filter holes of the inner tub are Φ5mm (open area ratio 40%), and the drain window 31 is set to Φ25mm (open area ratio 60%); the annular overflow port is provided with an annular overflow channel (80mm wide) 50mm above the inner tub.

[0031] 1. Vortex collection: Rainwater enters the guide cavity of the funnel through the grate 10 and is guided by the spiral guide groove 21 to form a forced vortex. Centrifugal force causes light debris to gather towards the center and fall into the collection bucket 30.

[0032] 2. Jet anti-siltation: High-speed water flow is accelerated through the V-shaped groove of the guide channel 21 and forms an upward jet through the nozzle 22, which washes away the sediment deposited at the bottom of the guide channel 21.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
