Technical Field

[0001] The utility model relates to the technical field of water conservancy facilities, in particular to a drainage device for water conservancy projects. Background Art

[0002] The drainage devices in water conservancy projects usually play the role of draining and diverting water bodies. Since the water environment is usually complex and contains a variety of debris that can easily cause clogging, in order to avoid clogging, some filtering devices are usually set up. When these filtering devices are in use, their filtering effects tend to continue to decrease, thereby reducing the water flow efficiency. Therefore, corresponding cleaning mechanisms are set up to clean the filtering devices. However, the existing cleaning mechanisms are relatively complex in structure, not convenient to use, and not conducive to maintenance and repair, highlighting the shortcomings of the existing technology.

DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-Figure 3As shown, a drainage device for water conservancy projects includes a drainage trough 1, a drainage pipe 2, and a stop valve 3. The front of the drainage trough 1 is penetrated, and a plurality of drainage pipes 2 are fixed to the rear. Each of the drainage pipes 2 is respectively installed with a stop valve 3. A support seat 4 is fixed to the front of the inner wall of the drainage trough 1. The left and right ends of the support seat 4 are fitted with the left and right ends of the inner wall of the drainage trough 1, and an arc-shaped filter screen plate 5 is fixed to the front end. The arc length of the filter screen plate 5 is less than a quarter of the circumference, and the bottom end is fitted with the top of the drainage trough 1. The rear of the support seat 4 is penetrated up and down, and a plurality of horizontal support rods 6 are fixed to the upper rear part. A horizontal collection trough 7 is placed on each of the support rods 6. The bottom of the collecting trough 7 is penetrated, and the lower filter screen 8 is sealed and fixed at the bottom penetration point. The left and right parts of the drainage trough 1 are each fixed with a support 9, and the right end of the right support 9 is fixed with a horizontal servo motor 10. The rotating shaft of the servo motor 10 is rotatably connected to the drainage trough 1 and the support 9, and the rotating shaft is coaxial with the virtual axis of the inner arc-shaped wall of the filter screen plate 5. The bottom end of the inner wall of the drainage trough 1 is tangent to the virtual circle of the inner arc-shaped wall of the filter screen plate 5. The rotating shaft of the servo motor 10 is radially fixed with a filter leakage plate 11 parallel to the rotating shaft of the servo motor 10, and the end edge of the filter leakage plate 11 away from the rotating shaft of the servo motor 10 is in contact with the inner arc-shaped wall of the filter screen plate 5.

[0015] During use, the water is allowed to flow from front to back along the drainage trough 1, while ensuring that the water surface does not submerge the filter screen plate 5. At this time, the water can be discharged from the drainage pipe 2 after being filtered by the filter screen plate 5, thereby realizing the drainage effect. Then the servo motor 10 is controlled to drive the filter leak plate 11 to move counterclockwise (right viewing angle), so that the debris intercepted by the front end of the filter screen plate 5 can be scraped until it falls into the collection trough 7 for drainage. When the collection trough 7 needs to be dumped, the servo motor 10 is controlled to stop, and then the collection trough 7 can be removed and dumped.

[0016] The servo motor 10 has a braking function, and a push plate 12 parallel to the rotating shaft of the servo motor 10 is radially fixed to the rotating shaft of the servo motor 10. The end edge of the push plate 12 away from the rotating shaft of the servo motor 10 can fit with the bottom end of the inner wall of the drainage groove 1 and the inner arc wall of the filter screen plate 5. The left and right ends of the push plate 12 are flush with the left and right ends of the inner wall of the drainage groove 1, and the filter leakage plate 11 and the push plate 12 are arranged at equal angles in a circle compared to the rotating shaft of the servo motor 10.

[0017] Furthermore, when it is necessary to quickly cut off the flow of water in the drainage trough 1, the servo motor 10 is controlled to rotate so that the end edge of the push plate 12 away from the rotating shaft of the servo motor 10 is in contact with the bottom end of the inner wall of the drainage trough 1, and then the brake is applied to cut off the water flow.

[0018] The left and right ends of the drainage trough 1 are each fixed with a horizontal mounting ear 13 for fastening the installation. The left and right parts of the top and the rear of the collecting trough 7 are fixed with a vertical intercepting bucket 14. The rear part of the intercepting bucket 14 is penetrated from front to back, and the penetration part of the rear part of the intercepting bucket 14 is sealed and fixed with an upper filter screen 15.

[0019] Furthermore, the drainage trough 1 can be conveniently fastened and installed by the mounting ear 13, and the interception bucket 14 is provided to improve the interception effect when the filter leak plate 11 or the push plate 12 pushes water backward and upward, so as to prevent water from overflowing the collection trough 7 and directly entering the rear part of the drainage trough 1, thereby reducing the filtering and interception effect of debris in the water body.

[0020] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, replacements and variations made to the implementation methods are still within the scope of protection of the present invention.
