Technical Field

[0001] The utility model provides a water filtration device, belonging to the technical field of hydraulic power engineering equipment, and particularly relates to a water filtration device for a hydraulic power pipeline. Background Art

[0002] Hydropower generation, also known as hydroelectric power, is a way of generating electricity by using the gravitational potential energy of water to drive a generator to rotate through a water turbine. It controls the water flow by building a dam or a reservoir, converts the potential energy of water flowing from a high place to a low place into mechanical energy, and then converts the mechanical energy into electrical energy through a water turbine and a generator. Hydropower generation is a renewable energy source because it relies on the water cycle, which is a natural and sustainable process.

[0003] In a hydropower generation system, the water flow usually needs to be transported to the water turbine through a long pipeline. If the water contains a large amount of impurities, sediment or other floating objects, it will cause wear and blockage to the pipeline and equipment, affecting the power generation efficiency and the service life of the equipment. Therefore, it is necessary to install a water filtration device. Under long-term use of the existing water filtration device, the filter screen will be blocked, affecting normal use. Cleaning the screen requires stopping and performing multiple disassembly steps, which is inconvenient to use. Summary of the Utility Model

A push plate corresponding to the connecting plate is arranged inside the support housing.

[0006] Preferably: The conveying pipe includes a filtering section housing sleeved outside the filtering structure. The inner diameter of the filtering section housing is smaller than the inner diameter of the conveying pipe, and inclined surfaces are arranged on both inner sides. An outer frame corresponding to the filtering section housing is sleeved outside the filter screen.

[0007] Preferably: T-shaped limiting plates inserted into the inside of the conveying pipe are fixedly connected to both sides of the outer frame. A cover corresponding to the shape of the conveying pipe and fixedly connected to the connecting plate is fixedly connected above the outer frame and the limiting plates. A bolt structure penetrating through itself and inserted into the inside of the support housing is arranged on the connecting plate.

[0025] As Figure 1 and Figure 2 As shown, a water filtration device for a hydroelectric power pipeline includes a delivery pipe 1, a filtration structure 2 provided inside the delivery pipe 1, and a filtration section housing 13 sleeved outside the filtration structure 2 in the delivery pipe 1. The inner diameter of the filtration section housing 13 is smaller than the inner diameter of the delivery pipe 1 and inclined surfaces 14 are provided on both inner sides. An outer frame 23 corresponding to the filtration section housing 13 is sleeved outside the filter screen 21. The filtration structure 2 includes a filter screen 21 penetrating through one side pipe body of the delivery pipe 1. The filter screen 21 is connected by a connecting plate 22 fixedly connecting the two to a support housing 11 sleeved outside the delivery pipe 1. A push plate 12 corresponding to the connecting plate 22 is provided inside the support housing 11.

[0026] In this implementation scheme, by setting the filtration structure 2 inside the delivery pipe 1, water filtration is directly carried out inside the pipe body during transportation. With the help of the connecting plate 22, the filter screen 21 and the delivery pipe 1 are movably connected. However, when it is necessary to clean the screen 21 to prevent blockage, the push plate 12 is used to push the screen 21 upward to separate the screen 21 from the delivery pipe 1.

[0027] As Figure 3 and Figure 4As shown, on both sides of the outer frame 23, there are fixedly connected T-shaped limit plates 24 inserted into the interior of the conveying pipe 1. Above the outer frame 23 and the limit plates 24, there is fixedly connected a cover 25 corresponding to the shape of the conveying pipe 1 and fixedly connected to the connecting plate 22. On the connecting plate 22, there is a bolt structure 26 passing through itself and inserted into the interior of the support housing 11. One end of the push plate 12 facing away from the connecting plate 22 is fixedly connected to a rectangular housing 15 inserted into the support housing 11. At the other end of the rectangular housing 15, there is a threaded column 16 inserted into its interior. The rectangular housing 15 is correspondingly meshed with the threaded column 16. The other end of the threaded column 16 is fixedly connected to a first crown gear 17. One side of the first crown gear 17 is connected to a rotary wrench 19 horizontally passing through the support housing 11 through a second crown gear 18 correspondingly meshed with itself.

[0028] In this embodiment, when the rotary handle 19 is rotated, the rotary wrench 19 drives the second crown gear 18 to rotate, driving the first crown gear 17 to rotate, so that the threaded column 16 rotates. Since the rectangular housing 15 is restricted by its own shape and cannot rotate and is correspondingly meshed with the threaded column 16, the rectangular housing 15 converts the rotational motion into a linear motion, thereby driving the push plate 12 to rise and push the connecting plate 22 and the filter screen 21 to rise; during the rising process of the filter screen 21, the limit plates 24 play a role in strengthening and stabilizing.

[0029] When in use:

[0030] 1. Install the equipment:

[0031] Install the filtering structure 2 inside the conveying pipe 1, ensure that the filter screen 21 correctly penetrates one side pipe body of the conveying pipe 1, and is fixedly connected to the support housing 11 sleeved outside the conveying pipe 1 through the connecting plate 22.

[0032] The filtering section housing 13 is sleeved outside the filter screen 21, ensure that the inner diameter of the filtering section housing 13 is smaller than the inner diameter of the conveying pipe 1, and there are inclined surfaces 14 on both inner sides, and the outer frame 23 corresponds to the shape of the filtering section housing 13.

[0033] Insert the limit plates 24 on both sides of the outer frame 23 into the interior of the conveying pipe 1, and fixedly connect the upper part of the outer frame 23 and the limit plates 24, so that it corresponds to the shape of the conveying pipe 1 and is fixedly connected to the connecting plate 22.

[0034] 2. Filtering of the filter screen:

[0035] Start the hydroelectric power generation system, and the water flows through the conveying pipe 1 and enters the filtering structure 2.

[0036] The water flow passes through the filter screen 21, and larger impurities are blocked by the filter screen 21, and the filtered water continues to flow through the conveying pipe 1.

[0037] 3. Clean the filter screen:

[0038] When the filter screen 21 needs to be cleaned, by rotating the rotary wrench 19, the rotary wrench 19 drives the second crown gear 18 to rotate, and then drives the first crown gear 17 to rotate.

[0039] The first crown gear 17 drives the threaded column 16 to rotate. Since the rectangular housing 15 and the threaded column 16 are correspondingly engaged, the rectangular housing 15 cannot rotate and can only move along the linear direction.

[0040] The linear movement of the rectangular housing 15 drives the push plate 12 to rise, and the push plate 12 drives the connecting plate 22 and the filter screen 21 to rise.

[0041] During the rising process of the filter screen 21, the limiting plate 24 ensures the stability and reinforcement of the filter screen 21 and the outer frame 23.

[0042] 4. Remove and clean the filter screen:

[0043] When the filter screen 21 completely rises and separates from the delivery pipe 1, manually take out the filter screen 21 for cleaning to remove the blocked impurities.

[0044] After cleaning, reinsert the filter screen 21 into the delivery pipe 1, and by rotating the rotary wrench 19, lower the push plate 12 to fix the filter screen 21 and the connecting plate 22 back to their original positions.

[0045] 5. Restore the filtering function:

[0046] After confirming that the filter screen 21 and the connecting plate 22 are securely fixed, continue to use the hydroelectric power generation system for normal water filtration operations.

[0047] Through the above steps, the utility model realizes effective filtration of the water flow in the hydroelectric power generation pipeline, and at the same time facilitates the cleaning and maintenance of the filter screen to ensure the normal operation of the system.

[0048] Although the utility model has been disclosed above with preferred embodiments, it is not intended to limit the utility model. Anyone familiar with this technology can make various modifications and decorations without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model should be defined by the claims.
