[0012] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0013] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manner.
[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0015] As Figures 1 to 2As shown in the figure, a drainage device for highway construction and maintenance includes a trench body 1, a drainage cover 2 is arranged on the trench body 1, a check component 3 is arranged on the lower side of the drainage cover 2, a filter plate 4 is installed on the lower side of the check component 3, the filter plate 4 is arranged along the extension direction of the trench body 1, front stop plates 41 and rear stop plates 42 are respectively arranged at both ends of the filter plate 4, the rear stop plates 42 are arranged vertically, the front stop plates 41 are arranged obliquely, and a groove 411 is arranged on the upper end surface of the front stop plates 41. One end of a first screw rod 5 is movably connected to the rear stop plate 42 through a sealed bearing, and the other end of the first screw rod 5 is connected to a second screw rod 6 through a universal joint. The second screw rod 6 is arranged along the groove 411. Specifically, in this embodiment, the trench body 1 is arranged on both sides of the road. A drainage cover 2 is arranged at the upper port of the trench body 1. The drainage cover 2 is formed by concrete casting, which is used to cover the trench body 1 to prevent pedestrians from accidentally stepping into the trench body 1 and at the same time prevent larger-volume dead branches and leaves from entering the trench body 1. A check component 3 is arranged under the drainage cover 2. The check component 3 adopts a valve structure with a downward-opening door. When draining water, the water mixed with sediment enters the check component 3. The internal valve structure of the check component 3 is washed by the water pressure and automatically opens. The water mixed with sediment enters the filter plate 4. The water is filtered and enters the bottom of the trench body 1 for discharge and collection, while sediment and other garbage are filtered by the filter plate 4 to avoid sediment and garbage accumulating at the bottom of the trench body 1 and being difficult to dredge. In order to facilitate the cleaning of sediment and garbage accumulated in the filter plate 4, a first screw rod 5 is installed at the bottom of the filter plate 4. The first screw rod 5 is connected to a second screw rod 6 obliquely placed in the groove 411 through a universal joint. A motor (not shown in the figure) is used to drive the first screw rod 5 to rotate, and then the second screw rod 6 can be driven to rotate synchronously in the groove 411. When the first screw rod 5 rotates, the silt accumulated at the bottom of the filter plate 4 can be conveyed through the spiral blades and along the groove 411 on the inclined front stop plate 41 and conveyed outwards to avoid sludge accumulating on the filter plate 4, blocking the holes on the filter plate 4 and reducing the filtering efficiency.
[0016] As Figures 1 to 2 shown, a step platform 11 is arranged at the port of the trench body 1, and the drainage cover 2 is installed at the step platform 11. Specifically, the step platform 11 is recessed downward to prevent the drainage cover 2 from protruding, so that it is flush with or lower than the road surface height.
[0017] As Figures 1 to 2As shown, the check assembly 3 includes a hanging plate 31 and a sealing plate 32. The two hanging plates 31 are installed under the step platform 11 in a mirror-symmetrical manner. One end of the two sealing plates 32 is connected to the hanging plate 31 through the torsion spring shaft, and the other ends of the two sealing plates 32 are in contact with each other and tilted downward. Specifically, the water passes through the drainage cover 2 and vertically downward, flushing on the sealing plate 32, so that the sealing plate 32 rotates around the torsion spring shaft to the side away from each other under the action of water pressure. The greater the water pressure impact force, the greater the gap between the two sealing plates 32. When the water pressure force is less than the torsion spring shaft force, the two sealing plates 32 move closer to each other again, abut against each other, and close the channel to prevent the odor of sludge and other filth accumulated on the filter plate 4 from rising, thereby ensuring a sanitary environment on both sides of the road.
[0018] like Figures 1 to 2 As shown, one end of the two sealing plates 32 that abut against each other is provided with saw teeth 321, and the saw teeth 321 of the two sealing plates 32 are staggered with each other. The saw teeth 321 of the two sealing plates 32 are staggered, and the meshing is more stable and reliable when separating and closing, and is not easy to deflect or misalign.
[0019] like Figures 1 to 2 As shown, the cross section of the filter plate 4 is V-shaped, and the first spiral rod 5 is buried at the bottom of the filter plate 4. Specifically, the V-shaped filter plate 4 allows the sludge on the plate surface to flow along the inclined plate surface and gather at the bottom of the filter plate 4 when the filter plate 4 is filtering, so that it is convenient to be transmitted out through the first spiral rod 5 and the second spiral rod 6.
[0020] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
