Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of road drainage, and more specifically relates to an anti-blocking drainage structure. Background Art
[0002] In order to prevent water accumulation on the roads, drainage outlets are set up on both sides of most road constructions. The drainage outlets are connected downward to the drainage ditch, and the drainage ditch is connected to the city sewer, so that the water on the road surface enters the sewer from the drainage ditch.
[0003] At the same time, in order to beautify urban roads, roadside trees or green belts are set on both sides of the road. The fallen leaves will float to the drain outlet with the water flow on the road surface and be blocked by the drainage cover on the drain outlet. When the leaves or other debris on the drainage cover accumulate on the through holes of the drainage cover, it will affect the drainage and cause waterlogging on the road. It is necessary to manually clean up the leaves and other obstructions on the drainage cover in time.
[0004] However, during heavy rain or typhoons, the rainfall outdoors is very heavy. Manual cleaning at this time will pose a great risk to personal safety. Therefore, cleaning is often not carried out immediately during heavy rain, resulting in water accumulation on the road after heavy rain, affecting the passage of pedestrians and vehicles on the road. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides an anti-blocking drainage structure to prevent the road drainage outlet from being blocked, reduce the amount of water accumulated on the road surface, and avoid affecting the passage of pedestrians and vehicles on the road surface.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-clogging drainage structure, comprising a drainage cover located at the top of the drain outlet, the drainage cover is provided with a plurality of drainage through holes, the cement foundation around the drain outlet supports the drainage cover, a plurality of water storage chambers are provided in the cement foundation around the bottom of the drainage cover, a float is provided in the water storage chamber, a float is provided on the float, the float passes through the drainage cover upward, an annular cover plate is provided between the protruding ends of the plurality of float rods, the drainage cover is provided with an annular groove corresponding to the annular cover plate, a blocking net is provided in the annular groove, one end of the blocking net is connected to the annular cover plate, and the other end is connected to the annular groove, a water inlet hole connected to the water storage chamber is provided on the inner wall of the drain outlet, a drainage hole is provided at the bottom of the water storage chamber, and the diameter of the drainage hole is smaller than the water inlet hole.
[0007] Furthermore, a gap is left between the bottom of the float and the bottom of the water storage chamber.
[0008] Furthermore, a water inlet channel is provided between adjacent water storage chambers, and a diameter of the water inlet channel is larger than the drainage hole.
[0009] Furthermore, a guide protrusion is provided below the water inlet hole, a guide groove is provided at the upper end of the guide protrusion, and three side surfaces of the guide groove are inclined toward the water inlet hole.
[0010] Furthermore, the guide protrusion corresponds to the drainage through hole.
[0011] Furthermore, the float ball and the float rod are both made of plastic.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when it rains heavily or rainstorms, the amount of water on the road increases, and the amount of accumulated water discharged from the drain outlet increases. Part of the water enters the water storage chamber, causing the float to rise, and then the annular cover plate is lifted up and the blocking net located in the annular groove is pulled up, forming a circle of interception barrier around the drainage cover, which is used to intercept leaf impurities in the accumulated water and prevent the drainage holes on the drainage cover from being blocked, effectively reducing the amount of water accumulated on the road during heavy rain or rainstorm, and avoiding affecting the passage of pedestrians and vehicles on the road; cleaning personnel can clean the leaf impurities around the outside after the rain stops, which is safer.

[0017] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. Therefore, the definition of "first" and "second" features can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" and "a number" is two or more, unless otherwise clearly and specifically defined.
[0018] Reference Figure 1 and Figure 2 The utility model is further described.
[0019] A blockage-proof drainage structure comprises a drainage cover 2 located at the top of a drainage outlet 1, the drainage cover 2 is provided with a plurality of drainage through holes 3, the drainage cover 2 is supported by a cement foundation around the drainage outlet 1, a plurality of water storage chambers 4 are provided in the cement foundation around the drainage cover 2, a floating ball 5 is provided in the water storage chamber 4, a floating rod 6 is provided on the floating ball 5, the floating rod 6 passes through the drainage cover 2 upward, an annular cover plate 7 is provided between the protruding ends of the plurality of floating rods 6, the drainage cover 2 is provided with an annular groove 8 corresponding to the annular cover plate 7, a blocking net 9 is provided in the annular groove 8, one end of the blocking net 9 is connected to the annular cover plate 7, and the other end is connected to the annular groove 8, a water inlet hole 10 connected to the water storage chamber 4 is provided on the inner wall of the drainage outlet 1, a drainage hole 11 is provided at the bottom of the water storage chamber 4, and the diameter of the drainage hole 11 is smaller than the water inlet hole 10.
[0020] like Figure 1 to Figure 2 As shown, when a large amount of water on the road surface begins to flow into the drain outlet 1 from the drain cover 2, a part of the falling water enters the water storage chamber 4 through the water inlet hole 10. Since the water inlet hole 10 is larger than the drain hole 11, water begins to accumulate in the water storage chamber 4. At this time, the float 5 in the water storage chamber 4 begins to rise due to the buoyancy, and the float rod 6 rises to lift the annular cover plate 7 and simultaneously pull up the blocking net 9 from the annular groove 8, thereby forming a circle of interception barriers formed by the blocking net 9 on the drain cover 2, so that leaves and impurities in the accumulated water on the road surface are blocked on the outside of the blocking net 9 to prevent them from clogging the drainage through hole 3 on the drain cover 2, thereby avoiding the drainage through hole 3 on the drain cover 2 from being blocked by leaves and impurities, and even when a large amount of leaves and impurities are accumulated outside the blocking net 9, the water flow can still be discharged into the drain outlet 1 from above the accumulated leaves and impurities through the blocking net 9, thereby ensuring the drainage of the road surface during the continuous heavy rain and rainstorm, and avoiding the accumulation of water on the road surface affecting the passage of pedestrians and vehicles;
[0021] When a large amount of accumulated water continues to be discharged, the water in the water storage chamber 4 can be continuously replenished to ensure the height of the blocking net 9. When the inflow of accumulated water decreases, the water flowing into the water storage chamber 4 will also gradually decrease, and the water in the water storage chamber 4 can be discharged through the drainage hole 11. The float 5 drops, which also means that the rain intensity is reduced and the road surface water is reduced. The cleaning personnel can go out to remove the leaves and impurities accumulated outside the blocking net 9 and in the annular groove 8, and fold the blocking net 9 back into the annular groove 8, and then cover the annular cover 7 on the annular groove 8 again to avoid cleaning during heavy rain and rainstorms, which is safer.
[0022] like Figure 1 As shown, in the present embodiment, preferably, a gap is left between the bottom of the float 5 and the bottom of the water storage chamber 4, so that the bottom of the float 5 is suspended in the air, and the gravity of the float 5 and the float rod 6 presses on the annular cover plate 7 to prevent the annular cover plate 7 from being easily lifted. At the same time, when the drainage volume is small, the water entering the water storage chamber 4 will not cause the float 5 to rise due to the buoyancy, and at this time, the drainage can be carried out solely by relying on the drainage cover 2.
[0023] like Figure 1 As shown, in this embodiment, preferably, a water inlet channel 12 is provided between adjacent water storage chambers 4, and the diameter of the water inlet channel 12 is larger than the drainage hole 11, so as to ensure that the water levels between the several water storage chambers 4 are the same and the rising height of the float 5 is the same.
[0024] like Figure 1 As shown, in the present embodiment, preferably, a guide protrusion 13 is provided below the water inlet hole 10, and a guide groove is provided at the upper end of the guide protrusion 13, and three side surfaces of the guide groove are inclined toward the water inlet hole 10 to facilitate guiding water into the water storage chamber 4.
[0025] like Figure 1 As shown, in the present embodiment, preferably, the guide protrusion 13 corresponds to the drainage through hole 3 , so as to conveniently guide the water left in the drainage through hole 3 into the water storage chamber 4 .
[0026] Preferably, in this embodiment, the float ball 5 and the float rod 6 are both made of plastic.
[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
