Description

Technical Field

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

[0002] A sluice gate in a water conservancy project is a device used to control the flow of water in water conservancy facilities. It is usually installed on the water passage of water conservancy structures such as canals, reservoirs, dams, and locks. It can regulate the flow and control the water level by opening or closing, and is a key facility in water conservancy projects to realize the rational utilization of water resources and multiple functions such as flood control, irrigation, and navigation.

[0003] When the gate body is submerged in water for a long time, aquatic organisms will adhere to the gate body. Since the gate body does not have a waterproof structure, the excessive aquatic organisms will increase the weight of the gate body, which will affect the overall lifting and lowering stability.

[0004] The existing patent (publication number: CN220364948U) discloses a water-resistant gate for biofouling. The water-resistant gate disclosed in this utility model has the technical effect of cleaning up biofouling when it is raised and lowered.

[0005] To address the aforementioned problems, existing patents have provided solutions. However, some existing devices for scraping aquatic organisms from the surface of hydraulic engineering gates are only convenient for cleaning aquatic organisms on one side of the gate. Especially when there is water on both sides of the gate, it is inconvenient to scrape aquatic organisms from both sides of the gate. Furthermore, it is difficult to completely remove the fine algae attached to the gate surface. The algae grow on the gate plate surface and form a biofilm. The presence of the biofilm not only provides physical roughness but also provides a food source for shellfish, which will quickly attract shellfish to reattach to the gate plate surface, making it difficult to reduce the attachment of aquatic organisms to the gate plate.

[0006] Therefore, a lifting gate for water conservancy projects is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A lifting gate for water conservancy projects includes two slide rails 1. A fixing plate 2 is fixedly connected between the top and bottom of the two slide rails 1 on opposite sides. A gate body 5 is slidably arranged between the two slide rails 1 on opposite sides. A rotating disk 6 is arranged on the top of the gate body 5. A scraping mechanism 4 is arranged on the front and rear sides between the two slide rails 1 on opposite sides. A flushing mechanism 3 is arranged between the two slide rails 1 on opposite sides. The gate body 5 is treated with a silane coupling agent modified coating.

[0029] The flushing mechanism 3 includes two water spray pipes 301, several water spray nozzles 302, a double-through pipe 303, and a pump body 304. The top of the water spray nozzles 302 is fixedly connected to the bottom of the water spray pipes 301. The bottoms of the front and rear water spray nozzles 302 are inclined toward one side of the gate body 5. The water spray pipes 301 are fixedly connected between the two slide rails 1 on opposite sides. The bottom of the double-through pipe 303 is fixedly connected to the drain end of the pump body 304. The side of the double-through pipe 303 near the water spray pipes 301 is fixedly connected to the water spray pipes 301.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, a support plate 15 is fixedly connected to the left side of the left slide rail 1, and the bottom of the pump body 304 is fixedly connected to the top of the support plate 15.

[0031] Specifically, such as Figure 5 As shown, a water inlet pipe 8 is provided at the bottom of the pump body 304. The top of the water inlet pipe 8 passes through the support plate 15 and is fixedly connected to the water inlet end of the pump body 304. A filter cover 14 is fixedly sleeved on the surface of the water inlet pipe 8.

[0032] In this embodiment: when the gate body 5 is moved upward by rotating the rotating disk 6, the pump body 304 is controlled to work. The pump body 304 can filter the water inside the channel through the filter cover 14 and enter the water inlet pipe 8. Then, the water is fed into the pump body 304 and fed into the spray pipe 301 through the double-pass pipe 303. Then, it is sprayed out through the spray nozzle 302, which can wash away the small algae remaining on the surface of the gate body 5 and wash away the biofilm formed by the algae growing on the gate body surface, reducing the re-attachment of shellfish. In addition, the silane coupling agent modified coating is sprayed on the surface of the gate body 5, which can create a chemical environment on the surface of the gate body 5 that is not conducive to the secretion of attachment substances by algae and shellfish, thereby further inhibiting their attachment.

[0033] Specifically, such as Figure 3 As shown, the scraping mechanism 4 includes two locking blocks 401, a connecting rod 402, and a scraper 403. The side of the locking block 401 closest to the slide rail 1 is fixedly connected to the slide rail 1. The connecting rod 402 is movably inserted between the opposite sides of the two locking blocks 401. The top of the scraper 403 is fixedly connected to the bottom of the connecting rod 402. The surface of the scraper 403 is in contact with the surface of the gate body 5.

[0034] Specifically, such as Figure 3 As shown, a pin 10 is provided on the top of the card block 401, and a magnetic block 9 is fixedly connected to the top of the pin 10. The bottom of the pin 10 passes through the card block 401 and extends into the interior of the connecting rod 402. The interiors of the card block 401 and the connecting rod 402 are in movable contact with the surface of the pin 10, and the bottom of the magnetic block 9 is magnetically attracted to the top of the card block 401.

[0035] In this embodiment: when the gate body 5 moves upward, the scraper 403 can scrape off the aquatic organisms attached to both sides of the gate body 5. When the scraper 403 needs to be replaced, simply pull the magnetic block 9 upward so that the magnetic block 9 is disengaged from the locking block 401 and the pin 10 is disengaged from the connecting rod 402. Then the connecting rod 402 and the scraper 403 can be pulled forward to disengage from the locking block 401 for cleaning or replacement.

[0036] Specifically, such as Figure 1 and Figure 4 As shown, a threaded post 7 is fixedly connected to the top of the gate body 5. The top of the threaded post 7 passes through the top fixing plate 2 and extends to the top of the top fixing plate 2. The surface of the threaded post 7 is in active contact with the interior of the top fixing plate 2. The rotating disk 6 is threadedly sleeved on the surface of the threaded post 7.

[0037] Specifically, such as Figure 1 and Figure 4As shown, a rotating ring 12 is movably sleeved on the surface of the rotating disk 6, and a bracket 13 is fixedly connected to the surface of the rotating ring 12. There are four brackets 13, which are evenly distributed on the surface of the rotating ring 12. The bottom of the bracket 13 is fixedly connected to the top of the top fixing plate 2.

[0038] Specifically, such as Figure 4 As shown, a number of levers 11 are fixedly connected to the top of the rotating disk 6 and are evenly distributed on the top of the rotating disk 6.

[0039] In this embodiment: through the threaded connection between the rotating disk 6 and the threaded column 7, the rotating ring 12 and the bracket 13 provide rotational support for the rotating disk 6, so that the rotating disk 6 can be rotated by hand using the lever 11. At this time, the threaded column 7 can drive the gate body 5 to move up and down, thereby realizing the opening and closing of the gate body 5.

[0040] Working principle: When the gate body 5 needs to be opened or closed, the rotating column 11 drives the rotating disk 6 to rotate. Since the rotating disk 6 is threadedly engaged with the threaded column 7, and the top of the threaded column 7 passes through and is in contact with the top fixed plate 2, the rotation of the rotating disk 6 will cause the threaded column 7 to rise or fall, thereby causing the gate body 5 to slide up and down between the two slide rails 1, realizing the opening and closing action of the gate body 5 to control the passage or cut off of water flow. The rotating disk 6 is easily rotated by the support of the rotating ring 12 and the bracket 13. During the upward movement and opening of the gate body 5, the scraper... Plate 403 can scrape off aquatic organisms attached to both sides of the gate body 5. When the gate body 5 moves upward and opens, the pump body 304 is activated. The pump body 304 filters the water inside the channel through the filter cover 14 and then enters the inlet pipe 8. The water then enters the pump body 304 and flows into the spray pipe 301 through the double-pass pipe 303. Finally, it is sprayed out through the spray nozzle 302, which washes away the fine algae remaining on the surface of the gate body 5 and removes the biofilm formed by algae growth on the gate body surface, reducing the re-attachment of shellfish. In addition, a silane coupling agent is sprayed on the surface of the gate body 5. The modified coating can create a chemical environment on the surface of the gate body 5 that is unfavorable to the secretion and attachment of algae and shellfish, thereby further inhibiting their attachment. This prevents the acidic or alkaline substances secreted by shellfish during attachment from undergoing electrochemical reactions with the metal gate body 5, which would lead to gradual corrosion of the metal surface. It also prevents changes in the pH of the surrounding water caused by algae photosynthesis, which could easily corrode the gate plate. Furthermore, it avoids the limitations of existing devices for scraping aquatic organisms from the surface of hydraulic engineering gates, which only clean one side of the gate, especially when there is water on both sides. It is inconvenient to scrape away aquatic organisms on both sides of the gate, and the fine algae attached to the gate surface are difficult to scrape off completely. The algae will grow on the gate plate surface and form a biofilm. The presence of the biofilm not only provides physical roughness, but also provides a food source for shellfish. It will quickly attract shellfish to attach to the gate plate surface again, making it inconvenient to reduce the problem of aquatic organisms attaching to the gate plate. When it is necessary to clean or replace the scraper 403, simply pull the magnetic block 9 and the pin 10 upward until the pin 10 is disengaged from the connecting rod 402, and the connecting rod 402 can be pulled out from inside the locking block 401 for easy cleaning or replacement.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
