Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a drainage device for water conservancy construction. Background Technology

[0002] Hydraulic engineering refers to various projects constructed to control, regulate, and utilize surface water and groundwater in nature to achieve the goals of harm prevention and benefit generation. Drainage devices in hydraulic engineering projects still have some defects and shortcomings in use, specifically requiring improvement as follows: 1. In general drainage devices, when blocking water flow, they only provide a simple barrier. However, sediment in the lower part of the water flow accumulates in front of the barrier, eventually hindering the barrier's downward flow. 2. Drainage devices often incorporate filtration structures, but weeds or fallen leaves in the water flow can clog these filters, necessitating the addition of specialized cleaning mechanisms to prevent blockage. Therefore, we propose a drainage device for hydraulic engineering projects. Utility Model Content

[0003] The main objective of this invention is to provide a drainage device for hydraulic structures that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A drainage device for hydraulic structures includes a housing. A support frame is fixedly connected to the middle of the upper end of the housing. A threaded rod is movably arranged through the middle of the upper end of the support frame. A rotating handle is fixedly connected to the upper end of the threaded rod. A barrier structure is movably arranged at the front end of the housing. A cleaning mechanism is movably arranged through the middle of the housing. A partition plate is fixedly connected to the rear of the left inner wall and the rear of the right inner wall of the housing. A filter bucket is fixedly connected to the middle of the partition plate. A sliding groove is fixedly connected to the front of the left end and the front of the right end of the housing.

[0006] Preferably, the barrier structure includes a barrier plate, a folded plate fixedly connected to the middle of the upper part of the barrier plate, side support rods fixedly connected to the front and rear ends of the folded plate, limit blocks fixedly connected to the lower left and lower right inner walls of the barrier plate, and several sets of connecting rods fixedly connected at equal intervals to the front end of the barrier plate. The ends of these connecting rods that do not contact the barrier plate are jointly fixedly connected to a front support plate. By adopting the above technical solution, the connecting rods have a triangular shape, which improves the stability between the connecting rods and the front support plate.

[0007] Preferably, the barrier plate is movably engaged with the sliding groove on the outer shell via a limiting block, and the folded plate is threadedly engaged with the threaded rod. By adopting the above technical solution, the front support plate has an arc-shaped structure and a smooth surface.

[0008] Preferably, the cleaning mechanism includes a rotating rod, with several sets of rectangular plates fixedly connected at equal intervals along the middle of the outer surface of the rotating rod. A rubber pad is fixedly connected to the end of each set of rectangular plates that does not contact the rotating rod. Limiting plates are fixedly connected to the left and right ends of the rotating rod. Extension cylinders are movably connected to the left and right sides of the rotating rod, and several sets of support shafts are movably connected to the inner walls of both sets of extension cylinders at equal intervals via U-shaped rods. By adopting the above technical solution, the rubber pads, being soft, can scrape the filter bucket for cleaning.

[0009] Preferably, the rotating rod passes through the outer casing, and the two sets of extension cylinders are fixedly connected to the left and right ends of the outer casing, respectively. By adopting the above technical solution, the limiting plates located on both sides of the extension cylinders can restrict the position of the rotating rod.

[0010] Preferably, the rubber pad contacts but is not fixed to the front end of the filter barrel, and the support shaft contacts but is not fixed to the rotating rod. By adopting the above technical solution, the support shaft can facilitate the rotation of the rotating rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting up a barrier structure, the barrier plate on the barrier structure can block the water flow without draining the water. The arc-shaped front support plate at the front can facilitate the flow of mud and sand at the bottom to the sides under the action of the water flow, reducing the accumulation of mud and sand at the front of the barrier plate. It is also convenient to turn the rotating handle to raise or lower the barrier plate.

[0013] 2. By setting up a cleaning mechanism, a rectangular plate is fixedly connected to the rotating rod on the cleaning mechanism. It can rotate under the impact of water flow, thereby driving the rubber pad to rotate as well, cleaning the left side of the filter bucket, which can effectively prevent the filter bucket from clogging when draining.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A drainage device for hydraulic structures includes a housing 1, a support frame 2 fixedly connected to the middle of the upper end of the housing 1, a threaded rod 3 movably arranged through the middle of the upper end of the support frame 2, a rotating handle 4 fixedly connected to the upper end of the threaded rod 3, a barrier structure 5 movably arranged at the front end of the housing 1, a cleaning mechanism 6 movably arranged through the middle of the housing 1, a partition plate 7 fixedly connected to the rear of the left inner wall and the rear of the right inner wall of the housing 1, a filter bucket 8 fixedly connected to the middle of the partition plate 7, and a sliding groove 9 fixedly connected to the front of the left end and the front of the right end of the housing 1.

[0024] In this embodiment, the barrier structure 5 includes a barrier plate 10. A folded plate 11 is fixedly connected to the middle of the upper end of the barrier plate 10. Side support rods 12 are fixedly connected to the front and rear ends of the folded plate 11. Limiting blocks 13 are fixedly connected to the lower left and lower right inner walls of the barrier plate 10. Several sets of connecting rods 14 are fixedly connected at equal intervals to the front end of the barrier plate 10. The ends of the several sets of connecting rods 14 that do not contact the barrier plate 10 are fixedly connected to a front support plate 15. The barrier plate 10 is movably engaged with the sliding groove 9 on the outer shell 1 through the limiting blocks 13. The folded plate 11 is threadedly engaged with the threaded rod 3. Through the above scheme, the barrier plate 10 on the barrier structure 5 can prevent water from draining out, and the arc-shaped front support plate 15 fixedly connected to the front through the connecting rods 14 can drive the silt at the bottom to flow to both sides when water flows through, preventing excessive accumulation of mud and sand at the lower end of the barrier plate 10 and hindering the descent of the barrier plate 10.

[0025] In this embodiment, the cleaning mechanism 6 includes a rotating rod 61. Several sets of rectangular plates 62 are fixedly connected at equal intervals on the middle of the outer surface of the rotating rod 61. A rubber pad 63 is fixedly connected to the end of each set of rectangular plates 62 that does not contact the rotating rod 61. Limiting plates 64 are fixedly connected to the left and right ends of the rotating rod 61. Extension cylinders 65 are movably connected to the left and right sides of the rotating rod 61. Several sets of support shafts 66 are movably connected to the inner walls of the two sets of extension cylinders 65 at equal intervals through U-shaped rods. The rotating rod 61 passes through the outer shell 1. The two sets of extension cylinders 65 are fixedly connected to the left and right ends of the outer shell 1, respectively. The rubber pad 63 contacts the front end of the filter bucket 8 but is not fixed. The support shafts 66 contact the rotating rod 61 but are not fixed. With the above solution: after the baffle plate 10 is opened, the water flows out of the filter bucket 8, and the rectangular plate 62 fixedly connected to the rotating rod 61 is driven to rotate together. The rubber pad 63 fixedly connected to the rectangular plate 62 can clean the front end of the filter bucket 8 during rotation, preventing the filter bucket 8 from becoming clogged.

[0026] It should be noted that this utility model is a drainage device for hydraulic structures. During use, when drainage is not required, the baffle plate 10 covers the front end of the outer shell 1, effectively preventing water leakage. The arc-shaped front support plate 15, fixedly connected to the front end of the baffle plate 10 via a triangular connecting rod 14, effectively prevents sediment accumulation in the outer shell 1 and the front of the baffle plate 10. Water flow will cause sediment to flow to both sides. When drainage is needed, the rotating handle 4 on the upper part of the threaded rod 3 is rotated. The rotating handle 4 causes the threaded rod 3 to rotate, opening the folded plate... The filter 11 moves upward together with the lower baffle plate 10, and the water flows out of the filter 8. The lower end of the side support rod 12, which is fixedly connected to the front and rear ends of the folded plate 11, is also fixedly connected to the baffle plate 10, which can strengthen the connection between the baffle plate 10 and the folded plate 11. The flowing water will drive the rectangular plate 62 on the rotating rod 61 to rotate together. The rubber soft pad 63 fixedly connected to the rectangular plate 62 can clean the front end of the filter 8 during rotation to prevent clogging. The rotating rod 61 contacts the support shaft 66 inside the extension tube 65, which can facilitate the rotation of the rotating rod 61.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
