Description

Technical Field

[0001] The invention belongs to the technical field of drainage, and in particular relates to a drainage cover plate. Background Art

[0002] Traditional gutter cover designs generally adopt the method of directly erecting on the gutter, and holes are set on the cover to achieve the drainage function. This design can meet the drainage needs under normal circumstances, but its limitations are exposed when facing sudden large-flow drainage.

[0003] When the water flow is small, the holes on the drain cover can effectively lead water into the drain and eventually drain it into the surrounding soil. However, when encountering heavy rain, floods or other situations that cause a sharp increase in water flow, these holes often cannot meet the drainage needs. A large amount of accumulated water cannot be discharged into the ditch in time, resulting in serious water accumulation on the ground and affecting drainage efficiency. In order to solve the above problems, manpower is needed to remove the drain cover so that a large amount of accumulated water can be discharged into the ditch, which requires a huge amount of labor. At the same time, the exposed drain mouth can easily cause passers-by to fall in, posing a great safety hazard.

[0004] With the acceleration of urbanization and the continuous increase of urban population, the burden on urban drainage systems is also increasing. The traditional drainage ditch cover design can no longer meet the needs of modern urban drainage systems.

[0005] Therefore, there is a need for a drainage cover that does not require manual operation and can conveniently and quickly drain road surface water into a drainage ditch to improve drainage efficiency. Summary of the invention

[0006] The purpose of the present invention is to provide a drainage cover plate, which can drain road surface water into a drainage ditch conveniently and quickly without human operation, thereby effectively improving drainage efficiency.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: A drainage cover plate comprises rotating cover plates which are relatively arranged on both sides of an opening of a drainage ditch with a gap between the opposite ends, a supporting rotating device which is correspondingly arranged in the drainage ditch and rotatably connected to the bottoms of the two rotating cover plates near their opposite ends, and a water collecting trough which is located in the drainage ditch and connected to the opposite ends of the two rotating cover plates through connecting pieces; the gap between the opposite ends of the two rotating cover plates is adapted to the leakage area of ​​the water collecting trough, and the side walls and the bottom of the water collecting trough are provided with a plurality of evenly arranged drainage holes.

[0008] A further improvement of the technical solution of the present invention is that: when the amount of accumulated water is small, the water collection tank is empty or not full, it is suspended in the drainage ditch by two rotating cover plates, and the two rotating cover plates close the two sides of the opening of the drainage ditch, and only the water is drained from the leaking area; when the amount of accumulated water is large and the water collection tank is full of water, it moves downward under the action of gravity, driving the two rotating cover plates to rotate around the supporting rotating device to open the two sides of the opening of the drainage ditch, and drain the water together with the leaking area.

[0009] A further improvement of the technical solution of the present invention is that the supporting rotating device includes a pin shaft arranged parallel to the length direction of the leakage area and rotatably connected to the bottom of the rotating cover plate, and a support rod symmetrically arranged at both ends of the pin shaft, one end of the support rod is connected to the inner wall of one side of the drainage ditch, and the other end thereof is tilted upward and connected to the end of the pin shaft.

[0010] A further improvement of the technical solution of the present invention is that the supporting rotating device includes a rotating shaft arranged parallel to the length direction of the water leakage area and rotatably connected to the bottom of the rotating cover plate, and both ends of the rotating shaft are respectively connected to the top inner wall of the drainage ditch.

[0011] A further improvement of the technical solution of the present invention is that blocks are symmetrically arranged on the inner walls on both sides of the opening of the drainage ditch, and the two blocks are respectively located at the bottom of the two rotating cover plates at one end away from the water leakage area.

[0012] A further improvement of the technical solution of the present invention is that the connecting member is located in the middle of the opposite ends of the rotating cover plate, and can adopt a connecting rope or an elastic rod with two ends respectively hinged to the rotating cover plate and the water collecting tank.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is: The drainage cover plate of the present invention can open or close the drainage inlet according to the amount of water, and can timely discharge the accumulated water into the drainage ditch, thereby improving the drainage efficiency.

[0014] The present invention cooperates with the water collecting trough through a rotating cover plate, and can open or close the two sides of the opening of the drainage ditch according to the water collection situation of the water collecting trough. When the amount of accumulated water is large and the water collecting trough is full of water, the water collecting trough can open the two sides of the opening of the drainage ditch under the action of its own gravity, so as to increase the drainage area and thus improve the drainage efficiency. When the amount of accumulated water is small and the water collecting trough is empty or not full of water, it is suspended in the drainage ditch by two rotating cover plates, and the two rotating cover plates close the two sides of the opening of the drainage ditch. This process does not require manual operation, and can effectively reduce labor costs.

[0015] The present invention has significant advantages in improving drainage efficiency, reducing labor costs, preventing property losses, improving safety, etc., and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with embodiments: Example 1 like Figure 1-Figure 3 As shown, this embodiment provides a drainage cover plate, including two rotating cover plates 2 that cooperate with each other, two supporting rotating devices and a water collecting trough 4.

[0018] Specifically, the two rotating cover plates 2 are arranged opposite to each other at two sides of the opening of the drainage ditch 1 , and there is a gap between the opposite ends of the two rotating cover plates 2 .

[0019] The two supporting rotating devices are adapted to the two rotating cover plates 2 and are correspondingly arranged in the drainage ditch 1. The two supporting rotating devices are respectively rotatably connected to the bottoms of the two rotating cover plates 2 near their opposite ends, that is, the rotating connection between the supporting rotating device and the rotating cover plate 2 is eccentrically arranged near the opposite end of the rotating cover plate 2, and the distance between the rotating connection and the opposite end of the rotating cover plate 2 is smaller than the distance between the rotating connection and the other end of the rotating cover plate 2.

[0020] The water collecting tank 4 is located in the drainage ditch 1. The water collecting tank 4 is connected to the opposite ends of the two rotating cover plates 2 through two connecting members 6. The side walls and the bottom of the water collecting tank 4 are provided with a plurality of evenly arranged drainage holes 7, so that the water collecting tank 4 can collect water and drain water at the same time. These drainage holes 7 are small-diameter holes. When the amount of accumulated water is small, the water in the water collecting tank 4 can be discharged into the drainage ditch 1 through these drainage holes 7, which will not increase or will not increase the weight of the water collecting tank 4 too much. The water collecting tank 4 is in an empty or not full state; when the amount of accumulated water is large, the water in the water collecting tank 4 does not have time to be discharged into the drainage ditch 1 through the drainage holes 7, and the water collecting tank 4 is in a full state, thereby increasing the weight of the water collecting tank 4. The connecting member 6 is located in the middle of the opposite end of the rotating cover plate 2, and it can be a connecting rope or an elastic rod with both ends hinged to the rotating cover plate 2 and the water collecting tank 4 respectively. The interval between the opposite ends of the two rotating cover plates 2 is a leakage area 3 adapted to the water collection trough 4. The leakage area 3 and the two rotating cover plates 2 are both rectangular structures. The sum of the areas of the three is adapted to the opening area of ​​the drainage ditch 1, and the width of the leakage area 3 is much smaller than the width of the rotating cover plates 2.

[0021] When the amount of accumulated water is small and the water collection tank 4 is empty or not full, it is suspended in the drainage ditch 1 by two rotating cover plates 2. The two rotating cover plates 2 close the two sides of the opening of the drainage ditch 1, and only the water is discharged from the leakage area 3; when the amount of accumulated water is large and the water collection tank 4 is full of water, it moves downward under the action of gravity, driving the two rotating cover plates 2 to rotate around the supporting rotating device to open the two sides of the opening of the drainage ditch 1, and drain water together with the leakage area 3.

[0022] Furthermore, the supporting rotating device includes a pin shaft and two supporting rods 5. The pin shaft is arranged parallel to the length direction of the leakage area 3, and the pin shaft is rotatably connected to the bottom of the rotating cover plate 2. The two supporting rods 5 are symmetrically arranged at both ends of the pin shaft. Specifically, one end of the support rod 5 is connected to the inner wall of the drainage ditch 1 away from the leakage area 3, and the other end thereof is tilted upward and connected to the end of the pin shaft. When the amount of accumulated water is large and the water collecting tank 4 is full of water, it moves downward under the action of gravity and drives the two rotating cover plates 2 to rotate around the pin shaft to open the two sides of the opening of the drainage ditch 1. When the amount of accumulated water is small and the water collecting tank 4 is empty or not full of water, the two rotating cover plates 2 rotate around the pin shaft to close the two sides of the opening of the drainage ditch 1, and suspend the water collecting tank 4 in the drainage ditch 1, and only the leakage area 3 is used for drainage.

[0023] Furthermore, two blocks 8 are symmetrically arranged on the inner walls on both sides of the opening of the drainage ditch 1, and the two blocks 8 are respectively located at the bottom of the two rotating cover plates 2 away from the leakage area 3. When the amount of accumulated water is small and the two rotating cover plates 2 rotate to close the two sides of the opening of the drainage ditch 1, the two blocks 8 are used to support the two rotating cover plates 2.

[0024] Example 2 The drainage cover provided in this embodiment has the same structure of other components except the supporting rotating device and the connection method between other components as in Embodiment 1, except that: The supporting rotating device includes a rotating shaft arranged parallel to the length direction of the leakage area 3, the rotating shaft is rotatably connected to the bottom of the rotating cover plate 2, and the two ends of the rotating shaft are respectively connected to the top inner wall of the drainage ditch 1. When the amount of accumulated water is large and the water collecting tank 4 is full of water, it moves downward under the action of gravity and drives the two rotating cover plates 2 to rotate around the rotating shaft to open the two sides of the opening of the drainage ditch 1. When the amount of accumulated water is small and the water collecting tank 4 is empty or not full of water, the two rotating cover plates 2 rotate around the rotating shaft to close the two sides of the opening of the drainage ditch 1, and suspend the water collecting tank 4 in the drainage ditch 1, and only the leakage area 3 is used for drainage.
