Description

Technical Field

[0001] This utility model relates to the technical field of drainage outlet guiding devices, specifically a drainage outlet guiding device for water conservancy and hydropower construction. Background Technology

[0002] When drainage equipment is working, the drainage source contains a large amount of impurities such as aquatic plants. After a long period of drainage, the drainage outlet will become blocked, which will affect subsequent drainage. In addition, during drainage, the drainage outlet is not easy to fix due to the water flow, which will prevent the water from being discharged to the designated location.

[0003] A search of Chinese patent CN221589825U reveals a drainage device for water conservancy and hydropower construction. This device utilizes a filter assembly located on one side of the inlet to initially filter the water, followed by a cutting tool to remove weeds and other impurities, effectively preventing blockages in the drainage pipe and ensuring proper drainage. A clamp is fitted onto the outer sheath, and two sets of fixed piles are symmetrically positioned on both sides of the drainage pipe. Two sets of rotating wheels further secure the piles to the ground, effectively limiting and fixing the drainage outlet and preventing loosening due to excessive water flow, which could prevent water from reaching its designated location.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. There is no suitable guiding structure to guide the drainage outlet during construction, which may cause backflow and backflow after the water enters the pipe, affecting the normal drainage work of construction. In addition, the structure blocked by impurities cannot be cleaned, which reduces the efficiency of the drainage outlet guiding device in water conservancy and hydropower construction. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage outlet guiding device for water conservancy and hydropower construction, so as to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is: a drainage outlet guiding device for water conservancy and hydropower construction, including a drainage pipe body for water conservancy and hydropower construction, a support pipe sleeved on one outer wall of the drainage pipe body, a guide frame fixedly connected to one outer wall of the support pipe, a flared opening on one outer wall of the guide frame, a sliding groove on the top outer wall of the guide frame, a filter frame slidably connected to the inner wall of the sliding groove, an installation hole on one outer wall of the filter frame, and a rotating shaft rotatably mounted on the inner walls of both sides of one side of the installation hole. A baffle is fixedly connected to the outer wall of shaft one. A torsion spring is provided on the outer wall of shaft one. A reset telescopic rod is fixedly connected to the other outer wall of the baffle. A circular groove is opened at one end of the piston rod of the reset telescopic rod. A rotating shaft two is rotatably arranged on the inner wall of the circular groove. A cleaning frame is fixedly connected to the outer wall of the rotating shaft two. A V-shaped plate is fixedly connected to the other inner wall of the mounting hole. Several filter holes are opened on one outer wall of the V-shaped plate. A slide rail is provided on one outer wall of the top and bottom of the V-shaped plate. The cleaning frame is slidably connected to the inner wall of the slide rail.

[0007] Preferably, the inner wall of the reset telescopic rod is provided with a reset spring, the mounting hole is adapted to the size of the drainage pipe body of the water conservancy and hydropower construction, and the baffle is adapted to the size of the V-shaped plate.

[0008] Preferably, the cleaning frame is slidably connected to the outer wall of the V-shaped plate, the distance between the cleaning frame and the filter holes is adapted, and a handle is installed on the top outer wall of the filter frame.

[0009] Preferably, the outer wall of the support tube is connected to a protective sleeve by a thread, a sealing gasket is fixedly connected to one side of the outer wall of the protective sleeve, and a reinforcing rod is fixedly connected to the four corners of the outer wall of the protective sleeve.

[0010] Preferably, a mounting plate is fixedly connected to one outer wall of the reinforcing rod. The mounting plate is arranged in a ring shape, and bolt holes are opened on one outer wall of the mounting plate. The size of the mounting plate is adapted to that of the guide frame.

[0011] This utility model provides an improved drainage outlet guiding device for water conservancy and hydropower construction, which has the following improvements and advantages compared with the prior art:

[0012] Firstly, this utility model, by setting up a guide frame, filter frame, baffle, reset telescopic rod, cleaning frame, and V-shaped plate, allows for smoother water flow through the flared opening. Pushing the two baffles on the filter frame causes them to open with the rotation of the first rotating shaft. The water is filtered through the filter holes on the V-shaped plate before entering the main body of the water conservancy and hydropower construction drainage pipe for discharge. After drainage is complete, a torsion spring on the outer wall of the first rotating shaft resets the baffles, and the two baffles close to seal the internal channel, preventing backflow. The outer wall of the baffles connects the second rotating shaft and the cleaning frame via the reset telescopic rod. Each time the baffles open and close, the cleaning frame slides on the slide rail of the V-shaped plate, cleaning the impurities clogging the filter holes and ensuring filtration efficiency. The baffles can be closed when no water is flowing in, effectively preventing backflow. Furthermore, each opening and closing of the baffles cleans the filter structure to a certain extent, improving the efficiency of the water conservancy and hydropower construction drainage outlet guide device.

[0013] Secondly, this utility model features a V-shaped plate, a protective sleeve, and a reinforcing rod. The V-shaped plate is inclined on both sides, making it less likely for filtered impurities to slide and remain, thus reducing the possibility of blockage. The outer wall of the support pipe is connected to the protective sleeve by threads, increasing the structural sealing. Furthermore, the structure is reinforced by the mounting plate and the reinforcing rod, improving the practicality of the drainage outlet guiding device for water conservancy and hydropower construction.

[0022] This utility model provides an improved drainage outlet guiding device for water conservancy and hydropower construction. The technical solution of this utility model is as follows:

[0023] like Figures 1-4 As shown, a drainage outlet guiding device for water conservancy and hydropower construction includes a drainage pipe body 1. A support pipe 4 is sleeved on one outer wall of the drainage pipe body 1. A guide frame 7 is fixedly connected to one outer wall of the support pipe 4. A flared opening 8 is formed on one outer wall of the guide frame 7. A sliding groove is formed on the top outer wall of the guide frame 7. A filter frame 6 is slidably connected to the inner wall of the sliding groove. An installation hole is formed on one outer wall of the filter frame 6. A rotating shaft 13 is rotatably arranged on the inner walls of both sides of the installation hole. A stop is fixedly connected to the outer wall of the rotating shaft 13. A torsion spring is provided on the outer wall of plate 14 and rotating shaft 13. A reset telescopic rod 9 is fixedly connected to the other outer wall of baffle 14. A circular groove is opened at one end of the piston rod of the reset telescopic rod 9. A rotating shaft 15 is rotatably arranged on the inner wall of the circular groove. A cleaning frame 11 is fixedly connected to the outer wall of rotating shaft 15. A V-shaped plate 10 is fixedly connected to the other inner wall of the mounting hole. Several filter holes 12 are opened on one outer wall of V-shaped plate 10. A slide rail 16 is provided on one outer wall of the top and bottom of V-shaped plate 10. The cleaning frame 11 is slidably connected to the inner wall of slide rail 16.

[0024] Furthermore, a reset spring is provided on the inner wall of the reset telescopic rod 9, the mounting hole is adapted to the size of the drainage pipe body 1 of the water conservancy and hydropower construction, the baffle 14 is adapted to the size of the V-shaped plate 10, the cleaning frame 11 is slidably connected to the outer wall of the V-shaped plate 10, the distance between the cleaning frame 11 and the filter hole 12 is adapted, a handle is installed on the top outer wall of the filter frame 6, and the guide frame 7 can only be used for drainage outlets in the field of water conservancy and hydropower construction.

[0025] Furthermore, the outer wall of the support tube 4 is connected to a protective sleeve 2 by threads. A sealing gasket is fixedly connected to one side of the outer wall of the protective sleeve 2. Reinforcing rods 3 are fixedly connected to the four corners of the outer wall of the protective sleeve 2. A mounting plate 5 is fixedly connected to one side of the outer wall of the reinforcing rod 3. The mounting plate 5 is arranged in a ring shape. Bolt holes are opened on one side of the outer wall of the mounting plate 5. The size of the mounting plate 5 is adapted to the guide frame 7. The outer wall of the support tube 4 is connected to the protective sleeve 2 by threads, which increases the structural sealing and reinforces the structure through the mounting plate 5 and the reinforcing rods 3.

[0026] Working principle: The guide frame 7 is connected to one side of the drainage pipe body 1 of the water conservancy and hydropower construction through the support pipe 4, and then the filter frame 6 is inserted. When drainage is needed, the water flows in through the flared opening 8 of the guide frame 7, which makes the water flow more smoothly. This pushes the two baffles 14 on the filter frame 6, causing the two baffles 14 to rotate and open with the rotating shaft 13. The water is filtered by the filter holes 12 on the V-shaped plate 10 before entering the drainage pipe body 1 of the water conservancy and hydropower construction and being discharged. When drainage is completed, the torsion spring on the outer wall of the rotating shaft 13 resets the baffles 14, and the two baffles 14 close to seal the internal channel and prevent drainage. When backflow occurs, the outer wall of the baffle 14 is connected to the rotating shaft 15 and the cleaning frame 11 via the reset telescopic rod 9. Each time the baffle 14 opens and closes, it drives the cleaning frame 11 to slide on the slide rail 16 of the V-shaped plate 10. The cleaning frame 11 cleans the impurities that clog the filter holes 12, ensuring the filtration effect and reducing the replacement frequency of the filter structure. The V-shaped plate 10 is inclined on both sides, so the filtered impurities are not easy to stay on the slide, reducing the possibility of clogging. The outer wall of the support pipe 4 is connected to the protective sleeve 2 by threads to increase the structural sealing, and the structure is reinforced by the mounting plate 5 and the reinforcing rod 3.
