[0002] Water conservancy projects are built to provide cities with water for production, life, etc., including various engineering facilities such as the collection and treatment of raw water and the distribution of finished water. They are also projects that build embankments on coastal mudflats to prevent tides and turn sea into land for the development of production. Water conservancy projects use buildings to concentrate the drop of natural water flow to form a head, and collect it in reservoirs to regulate the flow of natural water flow. Gates are control facilities used to close and open drainage channels.

[0003] In water conservancy projects, filters, as crucial components of gates, are responsible for filtering impurities from the water and protecting subsequent equipment from damage. However, prolonged operation can cause the filters to be eroded by water flow and abraded by debris, degrading their performance or even damaging them. Therefore, regular filter replacement is necessary. However, traditional gates are typically fixed to the filters, making replacement a complex and time-consuming process.

[0004] Therefore, it is necessary to design a water conservancy project drainage gate that is convenient to replace the filter screen. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example: A drainage gate for a water conservancy project, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a gate body 1, a first gate plate 2, a filter screen 3, a mounting frame 305, an electric rotating shaft 306, a latch 6, a second guide rod 601, a second spring 602 and a second valve plate 8. Two electric rotating shafts 306 are provided on the gate body 1. The gate body 1 is rotatably connected to the first gate plate 2 and the second valve plate 8 through the two electric rotating shafts 306. The two electric rotating shafts 306 respectively control the rotation of the first gate plate 2 and the second valve plate 8. The first gate plate 2 is movably connected to the mounting frame 305. The first gate plate 2 is fixedly connected to the second guide rod 601. The second guide rod 601 is slidably connected to the latch 6 for fixing the mounting frame 305. The second spring 602 is wound around the second guide rod 601. The two ends of the second spring 602 are respectively connected to the first gate plate 2 and the latch 6. The filter screen 3 is installed on the mounting frame 305.

[0023] like Figure 5 As shown, one side of the mounting frame 305 is fixedly connected to a fixing plate 301, and a first guide rod 303 is slidably connected to the interior of the fixing plate 301. The end of the first guide rod 303 away from the fixing plate 301 is fixedly connected to the baffle 302. A first spring 304 is wound around the first guide rod 303. The two ends of the first spring 304 are respectively connected to the fixing plate 301 and the end of the first guide rod 303 away from the baffle 302. The baffle 302 is movably connected to the mounting frame 305. Here, the baffle 302 slides outward. The baffle 302 drives the first guide rod 303 to move outward. At this time, the first spring 304 is compressed, and the baffle 302 no longer abuts against the fixed plate 301. The baffle 302 is released. At this time, the first spring 304 returns to its initial state. The first spring 304 pushes the first guide rod 303 during the recovery process, causing the first guide rod 303 to slide inward to the initial position. The first guide rod 303 drives the baffle 302 to move inward, causing the baffle 302 to abut against the fixed plate 301.

[0024] like Figure 1 and Figure 2As shown, the fixed plate 301 is slidably connected to the scraper 4, the scraper 4 is movably connected to the mounting frame 305 and the scraper 4 is parallel to the baffle 302, the side of the scraper 4 facing the baffle 302 is fixedly connected to the push rod 401, and the electric slide rail 5 is installed on the top of the gate body 1, and the slider 501 of the electric slide rail 5 is movably connected to the scraper 4. Here, the electric slide rail 5 is started, and the slider 501 of the electric slide rail 5 drives the scraper 4 to move, so that the scraper 4 moves to the other side of the mounting frame 305. The scraper 4 drives the push rod 401 to move during the movement. When the push rod 401 contacts the baffle 302, the push rod 401 pushes the baffle 302 outward.

[0025] like Figure 3 As shown, the bottom of the first gate plate 2 and the mounting frame 305 are fixedly connected with a sealing strip 603 for sealing the gap between the first gate plate 2 and the mounting frame 305 and the gate body 1. Here, the bottom of the second valve plate 8 is also provided with a sealing strip 603. When the first gate plate 2 or the second valve plate 8 is located in the gate body 1, the sealing strip 603 is designed to abut against the gate body 1, thereby closing the gap between the first gate plate 2 and the mounting frame 305 and the gate body 1 or the second valve plate 8 and the gate body 1, and preventing garbage debris from passing through the gap.

[0026] like Figure 1 and Figure 4 As shown, a fixed block 7 is fixedly connected to one side of the gate body 1, and a box body 701 is movably connected to the fixed block 7. A wire mesh 703 is provided on the box body 701. A limiting plate 702 for limiting the box body 701 is rotatably connected to one side of the fixed block 7. Here, the limiting plate 702 is flipped outward 180 degrees so that the limiting plate 702 no longer contacts the box body 701. The limiting plate 702 contacts the box body 701 to limit it, so that the box body 701 can be taken out, which is convenient for the subsequent centralized treatment of garbage in the box body 701. At the same time, the design of the wire mesh 703 can filter the water carried by the garbage, reduce the difficulty of subsequent garbage treatment, and provide convenience.

[0027] This device is mainly used in water conservancy engineering operations. After the device has been working for a long time, the filter screen 3 of the device is affected by water erosion and garbage wear, and the filter screen 3 of the device needs to be replaced. At this time, the electric shaft 306 is started, and the electric shaft 306 drives the second valve plate 8 to rotate 90 degrees, so that the second valve plate 8 flips downward and blocks the valve body. Then the electric shaft 306 drives the first gate plate 2 to rotate 90 degrees, so that the first gate plate 2 flips upward and is perpendicular to the valve body. During the flipping process, the first gate plate 2 drives the mounting frame 305 to flip, and the mounting frame 305 drives the scraper 4 to flip, so that the scraper 4 abuts against the slider 501 of the electric slide rail 5. Then the electric slide rail 5 is started, and the slider 501 of the electric slide rail 5 drives the scraper 4 to move, so that the scraper 4 moves to the other side of the mounting frame 305 and scrapes the garbage carried during the flipping process of the mounting frame 305. The scraper 4 drives the push rod 401 to move during the movement. When the push rod 401 contacts the baffle 302, the push rod 401 pushes the baffle 302 outward, and the baffle 302 moves outward under the force. The baffle 302 no longer blocks the garbage, and the scraper 4 scrapes the garbage into the box body 701, thereby completing the garbage cleaning work and facilitating the subsequent replacement of the filter 3. Then, the latch 6 can be slid outward to slide out of the slot provided on the installation frame 305. At this time, the second spring 602 is compressed, and the latch 6 no longer limits the installation frame 305, so that the installation frame 305 can be detached. Then, the filter screen 3 on the installation frame 305 is manually replaced. After the replacement is completed, the installation frame 305 is put back to its original position, and then the latch 6 is released. At this time, the second spring 602 returns to its initial state. The second spring 602 pushes the latch 6 during the recovery process, so that the latch 6 is inserted into the slot of the installation frame 305, thereby limiting and fixing the installation frame 305 again, and finally driving the first gate plate 2 and the second gate plate to rotate to the initial position in turn.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
