Description
Technical Field
[0001] The utility model relates to the technical field of road drainage, in particular to a road drainage cover plate with a self-cleaning function. Background Technique
[0002] A road drainage cover plate refers to a facility installed on a road to ensure road drainage and traffic safety. Road drainage cover plates are generally made of materials such as cast iron, steel plates, and resins. Different material cover plates are suitable for different environments and requirements. On urban roads and highways, road drainage cover plates are one of the indispensable facilities.
[0003] On the side of urban roads, in order to avoid road surface water accumulation, road drainage cover plates are often laid. When the road surface drainage volume is large, during the process of road water flowing towards the drainage cover plate, it is easy to carry debris such as road leaves or garbage and cover the upper part of the drainage cover plate. At this time, the drainage effect will be affected. In rainy weather with heavy rainfall, it is inevitable that rainwater will be difficult to drain in time, which will further lead to a large amount of road surface water accumulation and affect road traffic. Therefore, a road drainage cover plate with a self-cleaning function is proposed. Content of the Utility Model
[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a road drainage cover plate with a self-cleaning function.
[0005] To achieve the above purpose, the utility model provides the following technical solutions: A road drainage cover plate with a self-cleaning function, including a drainage cover plate body and a drainage groove, further including:
[0006] An automatic cleaning structure, which is arranged on the drainage cover plate body and is used for dredging impurities above the drainage groove;
[0007] Among them, the automatic cleaning structure includes a rotating shaft, the rotating shaft is rotatably connected to the inside of the drainage cover plate body, several groups of movable plates are installed on the outer surface of the rotating shaft, a water inlet hopper is fixed at one end of the movable plate, a counterweight is fixed at the other end of the movable plate, a cavity is opened inside the drainage cover plate body, a fixed shaft is installed inside the cavity, and a movable part and a return spring are sleeved on the outer surface of the fixed shaft.
[0008] As described above, the movable plate corresponds to the position of the drainage groove. When the movable plate rotates, one end of the movable plate can pass through the drainage groove and extend to the outside of the drainage groove.
[0009] As described above, the return spring elastically supports between the cavity and the movable part.
[0010] As described above, one side of the movable part is arc-shaped, and the surface of the movable plate is in pressing contact with the movable part.
[0011] As described above, when the inside of the water inlet hopper is filled with liquid, it can drive the movable plate to compress the movable part.
[0012] As described above, when the liquid inside the water inlet hopper is emptied, the counterweight can drive the movable plate to compress the movable part.
[0013] Compared with the prior art, the road drainage cover plate with self-cleaning function has the following beneficial effects:
[0014] First, due to the gravity of the water inlet hopper of the present invention, when the water inflow is large, the inside of the water inlet hopper will be filled with liquid. At this time, the water inlet hopper will be under pressure, driving the movable plate to rotate along the outer surface of the rotating shaft, thereby driving the movable plate to squeeze the movable part, causing the movable plate to drive the movable part to move along the outer surface of the fixed shaft. At this time, the movable part will release the block on the movable plate, causing one end of the movable plate to continuously rotate downward, and the other end of the movable plate will push aside the impurities on the top of the drainage groove to prevent blockage.
[0015] Second, due to the gravity of the counterweight of the present invention, when the water inlet hopper rotates to a certain angle, the liquid inside it will be discharged outward. At this time, the gravity of the water inlet hopper will decrease, and the gravity of the counterweight is much greater than the gravity of the water inlet hopper at this time, so as to drive the movable plate to reset, and then continuously and automatically dredge the upper part of the drainage groove.
[0016] Other advantages, objectives and features of the present invention will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] As Figures 1-4 shown, the present invention provides a road drainage cover plate with a self-cleaning function, including a drainage cover plate body 1 and a drainage groove 2, and further including:
[0024] An automatic cleaning structure, which is arranged on the drainage cover plate body 1 and is used for dredging impurities above the drainage groove 2;
[0025] Among them, the automatic cleaning structure includes a rotating shaft 3, the rotating shaft 3 is rotatably connected to the inside of the drainage cover plate body 1, several groups of movable plates 4 are installed on the outer surface of the rotating shaft 3, a water inlet hopper 5 is fixed at one end of the movable plate 4, a counterweight 6 is fixed at the other end of the movable plate 4, a cavity 7 is opened inside the drainage cover plate body 1, a fixed shaft 8 is installed inside the cavity 7, and a movable member 9 and a return spring 10 are sleeved on the outer surface of the fixed shaft 8.
[0026] Due to the gravity of the water inlet hopper 5, when the water inflow is large, the inside of the water inlet hopper 5 will be filled with liquid. At this time, the water inlet hopper 5 will be under pressure, driving the movable plate 4 to rotate along the outer surface of the rotating shaft 3, so as to drive the movable plate 4 to squeeze the movable member 9, making the movable plate 4 drive the movable member 9 to move along the outer surface of the fixed shaft 8. At this time, the movable member 9 will release the block on the movable plate 4, so that one end of the movable plate 4 will continue to rotate downward, and the other end of the movable plate 4 will push aside the impurities on the top of the drainage groove 2 to prevent blockage.
[0027] As Figure 1 、 2 shown, the position of the movable plate 4 corresponds to that of the drainage groove 2. When the movable plate 4 rotates, one end of the movable plate 4 can pass through the drainage groove 2 and extend to the outside of the drainage groove 2.
[0028] Through the design of the movable plate 4, since the position of the movable plate 4 corresponds to that of the drainage groove 2, when it continuously rotates, one end of it will extend to the outside of the drainage groove 2, so as to clean the impurities covering the surface of the drainage groove 2.
[0029] As Figure 4 shown, the return spring 10 is elastically supported between the cavity 7 and the movable member 9.
[0030] Through the design of the return spring 10, the movable member 9 has good elastic return performance. At this time, since the return spring 10 is in a compressed state, a elastic force will be exerted on the movable member 9, which can drive the movable member 9 to limit the movable plate 4. Therefore, when the liquid in the water inlet hopper 5 is insufficient, the rotation of the movable plate 4 can be restricted.
[0031] As Figure 2 、 4 shown, one side of the movable member 9 is arc-shaped, and the surface of the movable plate 4 is in pressing contact with the movable member 9.
[0032] Through the design of the movable member 9, since one side of the movable member 9 is arc-shaped, when the movable plate 4 presses against the movable member 9 and the pressure is sufficient, the movable member 9 can be driven to move along the outer surface of the fixed shaft 8, so that the blockage of the movable member 9 is released.
[0033] As Figure 2 、 4 shown, when the water inlet hopper 5 is filled with liquid, the movable plate 4 can be driven to compress the movable member 9.
[0034] By applying pressure to the water inlet hopper 5, the movable plate 4 can be driven to rotate along the outer surface of the rotating shaft 3. When the pressure of the water inlet hopper 5 reaches a certain level, the movable plate 4 can be driven to press against the movable member 9, causing the movable member 9 to release the blockage of the movable plate 4, facilitating the water inlet hopper 5 to drive the movable plate 4 to continue rotating downward.
[0035] As Figure 2 、 4 shown, when the liquid in the water inlet hopper 5 is emptied, the counterweight 6 can drive the movable plate 4 to compress the movable member 9.
[0036] Through the design of the counterweight 6, when the water inlet hopper 5 rotates to a certain angle, the liquid inside it will be discharged outward. At this time, the gravity of the water inlet hopper 5 will decrease, and the gravity of the counterweight 6 is much greater than the gravity of the water inlet hopper 5 at this time, so that the movable plate 4 can be driven to reset.
[0037] Working principle:
[0038] When the accumulated water on the road is relatively large, part of the liquid flowing into the drainage trough 2 will enter the interior of the water inlet hopper 5. At this time, the liquid will exert pressure on the water inlet hopper 5, which can drive the movable plate 4 to rotate along the outer surface of the rotating shaft 3 through the water inlet hopper 5. At this time, the movable plate 4 will press against the movable member 9, causing the movable plate 4 to drive the movable member 9 to move along the outer surface of the fixed shaft 8, making one end of the movable plate 4 continuously rotate downward, while the other end of the movable plate 4 will push aside the impurities at the top of the drainage trough 2. At the same time, when the water inlet hopper 5 continues to rotate, the liquid inside it will be discharged outward. At this time, the gravity of the counterweight 6 will drive the movable plate 4 and the water inlet hopper 5 to reset, facilitating the next dredging of the drainage trough 2.
[0039] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
