Description

Technical Field

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

[0002] The drainage channel used in water conservancy projects is a trench-type drainage facility with a specific structure. It can efficiently collect and discharge excess water in the water conservancy project area, avoid long-term water retention that could lead to erosion of the project structure, slope instability, soil salinization, or waterlogging of crops, and ensure the stable operation of water conservancy facilities and the normal function of the surrounding environment.

[0003] A search revealed Chinese Patent Publication No. CN223103577U, which discloses a drainage device for water conservancy projects, relating to the field of drainage technology for water conservancy projects. This drainage device for water conservancy projects includes a drainage channel and a limiting net. The drainage channel is equipped with a limiting net inside, a slag-blocking mechanism for intercepting floating objects inside, and a slag-removing mechanism for cleaning floating objects in the river channel inside. This type of drainage device for water conservancy projects uses high-pressure nozzles. When it is necessary to intercept and collect floating debris in the river channel, the sliding strips and baffle nets first intercept the floating debris. At this time, the water pump delivers water to the outlet pipe through the pumping pipe. The water in the outlet pipe is sprayed out through the high-pressure nozzles. While spraying water, the high-pressure nozzles also flush the floating debris on the water surface into the collection tank. The limiting net facilitates the collection of floating debris inside the collection tank, making subsequent dredging and cleaning convenient. This device is convenient for intercepting and collecting floating debris in the river channel. However, when the drainage channel for water conservancy projects is in use, the water flow will not only contain floating debris, but also silt and small stones mixed in with the water flow. This causes silt or small stones to accumulate in the drainage channel, causing blockage and reducing the drainage efficiency of the drainage channel. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drainage channel for water conservancy projects, aiming to improve the problem that the drainage channel is blocked by mud or small stones during use, affecting the normal drainage of the drainage channel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drainage ditch for water conservancy projects, comprising a ditch body, a filter mechanism provided at the bottom of the ditch body for facilitating the sedimentation of silt in the water flow, and a cleaning mechanism provided on the right side of the bottom of the ditch body for facilitating the cleaning of debris by workers; The filtration mechanism includes a sedimentation tank, which is fixedly connected to the bottom front side of the tank body. A first filter screen is fixedly connected to the front inside of the sedimentation tank, and a second filter screen is fixedly connected to the left side inside the tank body. A support is provided on the top of the sedimentation tank. Water baffles are rotatably connected to the front and rear sides of the bottom of the support. Fixed plates are fixedly connected to the left and right sides of the bottom of the support. A hollow plate is provided at the bottom of the fixed plate. A guide rod is fixedly connected to the inner side of the hollow plate. A slider is slidably connected to the rear side of the outer wall of the guide rod. A spring is provided on the outer side of the hollow plate. A connecting rod is rotatably connected to one side of the slider. The front end of the connecting rod is rotatably connected to the water baffle.

[0006] With the above technical solution, when the water flows through the sedimentation tank, it will first be filtered by the filter screen to filter out stones and floating objects. Furthermore, when the water flows through the sedimentation tank, it will be blocked by the baffle plate, which will slow down the water flow and allow the silt in the water to settle down. As a result, the water entering the tank will not contain silt or floating objects, thus preventing the tank from becoming blocked.

[0007] As a further description of the above technical solution: The cleaning mechanism includes an equipment well, which is fixedly connected to the bottom right side of the tank. A threaded rod is rotatably connected to the inner center of the equipment well, and a movable plate is threadedly connected to the outer wall of the threaded rod. Support columns are fixedly connected to the front and rear ends of the left side of the movable plate. The left ends of the support columns penetrate the equipment well. A first push plate is fixedly connected to the left end of the rear support column, and a second push plate is fixedly connected to the left end of the front support column. A drive assembly is provided inside the equipment well.

[0008] Through the above technical solution, the rotation of the threaded rod will drive the movable plate to move, which in turn will drive the first push plate and the second push plate to move through the support column, pushing the floating objects or silt to the left side of the sedimentation tank, so that the waterway will not be blocked and the normal flow of water will not be affected.

[0009] As a further description of the above technical solution: The drive assembly includes a motor and a timing belt. The motor is fixedly connected to the front side of the equipment well. Pulleys are fixedly connected to the output end of the motor and the outer side of the threaded rod. The two pulleys are connected by the timing belt.

[0010] Through the above technical solution, the motor can drive the threaded rod to rotate through the transmission action of the pulley and the transmission belt, thereby realizing the movement of the movable plate.

[0011] As a further description of the above technical solution: The filtration mechanism also includes screws, and multiple screws are threadedly connected to the bottom of the front and rear sides of the corresponding fixing plates. The bottom end of the screws passes through the fixing plate and is threadedly connected to the hollow plate.

[0012] With the above technical solution, when the spring needs to be replaced, the hollow plate can be removed by unscrewing the bolts, ensuring that the spring force is within a suitable range.

[0013] As a further description of the above technical solution: The filtration mechanism also includes a flow-blocking block, which is fixedly connected to the rear side of the interior of the sedimentation tank, and the outer side of the slider is slidably connected to the hollow plate.

[0014] Through the above technical solution, the baffle block can prevent the sediment from being carried out of the sedimentation tank when the water flows out from the bottom of the sedimentation tank, and the slider can slide inside the hollow plate.

[0015] As a further description of the above technical solution: The filtration mechanism also includes bolts, two of which are threaded to the left and right sides of the bracket respectively, and the bottom end of the bolts penetrates the bracket and is threaded to the groove.

[0016] By removing the bolts on the bracket using the above technical solution, the bracket can be disassembled, thereby cleaning the scale on the outside of the baffle.

[0017] As a further description of the above technical solution: The cleaning mechanism also includes a top cover, which is installed on the top of the equipment well. Hinges are fixedly connected to the left and right sides of the top front end of the top cover, and the top cover is rotatably connected to the equipment well through the hinges.

[0018] The above technical solution allows for easy opening of the top cover, enabling maintenance of the equipment inside the equipment well.

[0019] As a further description of the above technical solution: The cleaning mechanism also includes a controller, which is fixedly connected to the top of the cover and electrically connected to the motor.

[0020] Through the above technical solution, the controller can control the operation of the motor.

[0021] This utility model has the following beneficial effects: 1. In this utility model, when water flows through the sedimentation tank, it is filtered by a filter screen, and floating objects and stones in the water can be filtered out. In addition, the water flow in the sedimentation tank is blocked by a baffle plate, which slows down the water flow speed. The silt in the water will settle at the bottom of the sedimentation tank, so that the water flowing through the tank will not carry silt and floating objects, avoid the tank from being blocked, and improve the drainage effect of the tank.

[0022] 2. In this utility model, the motor drives the threaded rod to rotate through the transmission action of the pulley and the synchronous belt, thereby further driving the movable plate to move to the left. The movable plate pushes the first push plate and the second push plate to move to the left through the two support columns respectively. The second push plate pushes the floating objects and small stones accumulated on the filter screen to the left side of the sedimentation tank, so that the filter screen will not be blocked. The first push plate can push the silt at the bottom of the sedimentation tank to the left, which makes it convenient for the staff to collect and clean the silt, and can prevent silt or floating objects from blocking the water flow channel.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a drainage ditch for water conservancy projects, including a ditch body 1, a filter mechanism 2 is provided at the bottom of the ditch body 1, the filter mechanism 2 is used to facilitate the sedimentation of mud and sand in the water flow, and a cleaning mechanism 3 is provided on the right side of the bottom of the ditch body 1, the cleaning mechanism 3 is used to facilitate the cleaning of debris by the staff. The filtration mechanism 2 includes a sedimentation tank 21, which is fixedly connected to the bottom front side of the tank body 1. A first filter screen 22 is fixedly connected to the front inside the sedimentation tank 21. The first filter screen 22 is used to filter stone particles and floating matter. A second filter screen 23 is fixedly connected to the left side inside the tank body 1. The second filter screen 23 can prevent floating matter from re-mixing into the water flow. A support 24 is provided at the top of the sedimentation tank 21. Water baffles 25 are rotatably connected to the front and rear sides of the bottom of the support 24. The water baffles 25 are used to slow down the water flow. Fixing plates 26 are fixedly connected to the left and right sides of the bottom of the support 24. A hollow plate 27 is provided at the bottom of the fixing plate 26. The inner side of the hollow plate 27 is fixedly connected to... The filter mechanism 2 includes a guide rod 28, a slider 29 which is slidably connected to the rear side of the outer wall of the guide rod 28, and the slider 29 can slide on the outside of the guide rod 28. A spring 210 is provided on the outside of the hollow plate 27. A connecting rod 211 is rotatably connected to one side of the slider 29. The front end of the connecting rod 211 is rotatably connected to the baffle plate 25. When the baffle plate 25 is rotated by the water flow, the connecting rod 211 can push the slider 29 to move, thereby compressing the spring 210. The filter mechanism 2 also includes a baffle block 213, which is fixedly connected to the rear side of the sedimentation tank 21. The outside of the slider 29 is slidably connected to the hollow plate 27, so that the slider 29 will not deflect when it slides. Specifically, when using this device, water flows through the tank 1 to achieve drainage. When the water flows through the sedimentation tank 21 in the tank 1, it is initially filtered by the filter screen 22, which can effectively intercept floating objects and large small stones in the water flow, preventing these impurities from entering the subsequent tank 1. The water flow continues to pass through the sedimentation tank 21, where it is blocked by the baffle plate 25, which slows down the flow speed. The silt carried in the water flow will gradually settle due to gravity and eventually accumulate at the bottom of the sedimentation tank 21, thereby effectively screening and separating the silt and various floating objects, improving the drainage effect of the tank 1. When the water flow in the tank 1 is large, the water flow will push the baffle plate 25 to rotate. The rear side of the baffle plate 25 is connected to the slider 29 through the connecting rod 211. When the baffle plate 25 rotates, the connecting rod 211 will drive the slider 29 to move, thereby further compressing the spring 210, so that the water channel can be opened, avoiding the overflow problem when the water flow is large.

[0027] Reference Figure 1 , Figure 5 and Figure 6The cleaning mechanism 3 includes an equipment well 31, which is fixedly connected to the bottom right side of the tank 1. A threaded rod 32 is rotatably connected to the inner center of the equipment well 31. A movable plate 33 is threadedly connected to the outer wall of the threaded rod 32. When the threaded rod 32 rotates, the movable plate 33 moves accordingly. Support columns 34 are fixedly connected to the front and rear ends of the left side of the movable plate 33. The movable plate 33 will drive the two support columns 34 to move to the left. The left ends of the support columns 34 all penetrate the equipment well 31. A first push plate 35 is fixedly connected to the left end of the rear support column 34, and a second push plate 36 is fixedly connected to the left end of the front support column 34. The two support columns 34 will respectively drive the first push plate 35 and the second push plate 36 to move to the left. The inner side of the equipment well 31 is provided with The device includes a drive assembly 37, which comprises a motor 371 and a timing belt 373. The motor 371 is fixedly connected to the front of the equipment well 31. The output end of the motor 371 and the outer side of the threaded rod 32 are both fixedly connected to pulleys 372. The two pulleys 372 are connected by the timing belt 373. The motor 371 can drive the threaded rod 32 to rotate through the transmission action of the pulleys 372 and the timing belt 373. The cleaning mechanism 3 also includes a top cover 38, which is set on the top of the equipment well 31. The top front end of the top cover 38 is fixedly connected to the left and right sides of the top. The top cover 38 is rotatably connected to the equipment well 31 through the hinges 39. Opening the top cover 38 makes it convenient to maintain the equipment in the equipment well 31. Specifically, when the floating matter or silt inside the sedimentation tank 21 accumulates to a considerable extent, the motor 371 will start and drive the front pulley 372 to rotate. Through the transmission action between the synchronous belt 373 and the pulley 372, the threaded rod 32 can be further driven to rotate. During the rotation of the threaded rod 32, it will drive the movable plate 33 on its outer side to move to the left. The movement of the movable plate 33 will further drive the two support columns 34 to move to the left. The front support column 34 will push the second push plate 36 to move to the left, which can push the floating matter and small stones accumulated on the filter screen 22 to the left side of the sedimentation tank 21, thereby ensuring that the filter screen 22 will not be blocked due to the accumulation of debris. At the same time, the rear support column 34 will drive the first push plate 35 to move to the left, pushing the silt at the bottom of the sedimentation tank 21 to the left, so that the silt can be concentrated on one side, making it convenient for collection and cleaning. This not only effectively prevents silt or floating matter from blocking the water flow channel, but also greatly improves the maintenance efficiency of the sedimentation tank 21.

The bottom end of the bolts 214 passes through the bracket 24 and is threadedly connected to the tank 1. The bracket 24 can be easily disassembled by removing the bolts 214, thereby removing the baffle plate 25. Specifically, the hollow plate 27 can be removed by unscrewing screw 212, thereby replacing the spring 210 to maintain optimal elasticity. The bracket 24 can be removed by tightening bolt 214, making it convenient to clean the scale adhering to the surface of the baffle plate 25.

[0029] Reference Figure 1 , Figure 3 and Figure 5 The cleaning mechanism 3 also includes a controller 310, which is fixedly connected to the top of the top cover 38. The controller 310 is electrically connected to the motor 371 and can control the operation of the motor 371. Specifically, the controller 310 can control the operation of the motor 371, the model of which is MS8012, and the controller 310 is Beckhoff CP6906.

[0030] Working principle: When using this device, water flows through the tank 1 to achieve drainage. When the water flows through the sedimentation tank 21 in the tank 1, it is first filtered by the filter screen 22, which filters out floating objects and large and small stones in the water. When the water flows through the sedimentation tank 21, it is blocked by the baffle plate 25, which slows down the water flow. The silt in the water will settle down due to the slow water flow and accumulate at the bottom of the sedimentation tank 21. It can accurately screen out silt and various floating objects. When the water flow is large, the water flow will push the baffle plate 25 to rotate. Since the back of the baffle plate 25 is connected to the slider 29 through the connecting rod 211, when the baffle plate 25 rotates, the connecting rod 211 can push the slider 29 to move. The movement of the slider 29 will compress the spring 210, thereby opening the water channel when the water flow is large and preventing water from overflowing. Furthermore, when there is a large amount of floating matter or silt inside the sedimentation tank 21, the motor 371 will drive the front pulley 372 to rotate, and through the transmission action of the synchronous belt 373 and the pulley 372, it can drive the threaded rod 32 to rotate. When the threaded rod 32 rotates, it can drive the movable plate 33 on its outer side to move to the left. The movable plate 33 will drive the support column 34 to move, and the front support column 34 will drive the second push plate 36 to move to the left, pushing the floating matter and small stones accumulated on the filter screen 22 to the left side of the sedimentation tank 21, so that the filter screen 22 will not be blocked. The rear support column 34 will drive the first push plate 35 to move to the left, pushing the silt at the bottom of the sedimentation tank 21 to the left, which can facilitate the collection and cleaning of silt and prevent silt or floating matter from blocking the water flow channel.
