Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0033] Example 1 Reference Figures 1-3 A schematic diagram of the overall structure of a sand discharge gate is provided. The sand discharge gate includes a gate assembly 100, comprising a gate body 101 and a sealing strip 102 disposed on the side of the gate body 101. The gate body 101 is used for reservoir water discharge, and the sealing strip 102 is used to seal the gate body 101 to prevent poor sealing between the dam / reservoir and the sand discharge gate, thus avoiding water waste. A sand discharge port 101a is provided at the lower end of the gate body 101, and a protective base frame 101b is provided at the lower end of the sand discharge port 101a. The protective base frame 101b is fixedly connected to the gate body 101. A sliding rod 101c is provided on the upper side, and a protective top frame 101d is provided on the upper end of the sand discharge port 101a. The protective top frame 101d is slidably connected to the gate body 101. The protective top frame 101d is provided with a sliding hole 101e and a tension spring 101f. The sliding hole 101e cooperates with the sliding rod 101c, and the tension spring 101f is sleeved on the sliding rod 101c. One end of the tension spring 101f is fixedly connected to the protective top frame 101d, and the other end of the tension spring 101f is fixedly connected to the gate body 101. The protective bottom frame 101b cooperates with the protective top frame 101d.

[0034] Furthermore, the plug-in assembly 200 includes a first plug-in member 201 disposed on the protective base frame 101b and an auxiliary plug-in member 202 fixedly connected to the first plug-in member 201. The auxiliary plug-in member 202 improves the plug-in and fixing effect of the first plug-in member 201, providing double protection. The snap-fit ​​assembly 300 includes a rotating member 301 disposed on the gate body 101, a first snap-fit ​​member 302 disposed on the protective top frame 101d, auxiliary snap-fit ​​members 303 disposed on both sides of the first snap-fit ​​member 302, and an adjusting member 304 disposed between the first snap-fit ​​member 302 and the auxiliary snap-fit ​​members 303. The rotating member 301 is the protective base frame 101b. The frame 101b and the protective top frame 101d are engaged to provide power for the protection of the sand discharge port 101a, and to provide power for the protective base frame 101b and the protective top frame 101d to make contact and engage for faster discharge of silt. The first plug-in part 201 and the first locking part 302 cooperate, and the locking and fixing state of the first plug-in part 201 and the first locking part 302 is locked by the adjusting part 304. The cooperation of the auxiliary plug-in part 202 and the auxiliary locking part 303 locks and engages the first plug-in part 201 and the first locking part 302 again, thereby realizing the fixed engagement of the protective base frame 101b and the protective top frame 101d.

[0035] Operation process: The gate body 101 is installed at the dam reservoir for water discharge and flood discharge when necessary. The sand discharge port 101a on the gate body 101 is used to clean and discharge silt from the bottom of the dam reservoir during normal water storage. The rotating component 301 rotates 180 degrees, pressing the protective top frame 101d towards the mounting base along the sliding rod 101c until the first insertion component 201 and the first locking component 302 engage and fix it. The auxiliary insertion component 202 and the auxiliary locking component 303 also engage and fix it, thus achieving the fixed engagement of the protective base frame 101b and the protective top frame 101d. Adjustment... The cooperation between component 304 and tension spring 101f locks the fixed engagement of the protective base frame 101b and the protective top frame 101d, preventing the protective base frame 101b and the protective top frame 101d from being loosely fixed and causing fish to accidentally enter the sand discharge port 101a, resulting in extinction and affecting the protective effect. Similarly, by rotating component 301 by rotating it 180 degrees, the fixed engagement of the protective base frame 101b and the protective top frame 101d is released, improving the sand discharge effect and protecting the sand discharge port 101a of the sand discharge gate, thus protecting migratory fish. It can also be determined whether to protect the sand discharge port 101a according to the actual working conditions.

The ear plate 201c is fixedly connected to the non-inclined side wall of the connector block 201b. The auxiliary connector 202 includes a support post 202a, a sliding ring 202b, and an arc... The arc-shaped protrusion 202c is fixedly connected to the support column 202a and the ear plate 201c. The sliding ring 202b is slidably connected to the support column 202a and is sleeved on the support column 202a. The lower end of the arc-shaped protrusion 202c is fixedly connected to the upper end of the support column 202a. The lower end of the arc-shaped protrusion 202c is provided with a groove 202c-1. The groove 202c-1 cooperates with the top of the sliding ring 202b to facilitate the release of the locking and fixing state between the auxiliary plug 202 and the auxiliary snap-fit ​​block 302b.

[0037] Specifically, the rotating component 301 includes a motor 301a and an abutting rotating rod 301b. The motor 301a is fixedly connected to the gate body 101, and the abutting rotating rod 301b is fixedly connected to the rotating shaft of the motor 301a. One end of the abutting rotating rod 301b is closer to the motor 301a. After the end of the abutting rotating rod 301b closer to the motor 301a abuts against the protective top frame 101d, the first insertion component 201 and the first locking component 302 are locked together. The other end of the abutting rotating rod 301b is farther from the motor 301a. After the end of the abutting rotating rod 301b farther from the motor 301a abuts against the protective top frame 101d, the locking state of the first insertion component 201 and the first locking component 302 is released. The first locking component 302 includes a mounting slide 302a and an auxiliary locking block 302. b. The first snap-fit ​​component 302 includes a snap-fit ​​claw 302c, an elastic plate 302d, and a first compression spring 302e. The mounting slide 302a is fixedly connected to the protective top frame 101d, and the auxiliary snap-fit ​​block 302b is fixedly connected to the mounting slide 302a. The snap-fit ​​claw 302c is hinged to the auxiliary snap-fit ​​block 302b, and the snap-fit ​​claw 302c cooperates with the insertion block 201b. The first snap-fit ​​component 302 also includes an elastic plate 302d and a first compression spring 302e. One end of the elastic plate 302d is movably connected to the auxiliary snap-fit ​​block 302b, and the other end of the elastic plate 302d is movably connected to the snap-fit ​​claw 302c. One end of the first compression spring 302e is fixedly connected to the mounting slide 302a, and the other end of the first compression spring 302e is fixedly connected to the mounting slide 302a. The elastic plate 302d is used to open the snap-fit ​​claw 302c and the auxiliary snap-fit ​​block 302b for easy use next time.

[0038] Furthermore, the auxiliary snap-fit ​​component 303 includes a fixed housing 303a, a slanted slider 303b, and a first return spring 303c. The fixed housing 303a is fixedly connected to the top of the mounting cylinder 302a. A sliding groove 303a-1 is provided at the lower end of the fixed housing 303a. The slanted slider 303b is disposed in the sliding groove 303a-1 and is slidably connected to the sliding groove 303a-1. When the first insert 201 and the first snap-fit ​​component 302 are in a snap-fit ​​fixed state, the slanted slider 303b abuts against the lower part of the arc-shaped protrusion 202c to achieve further snap-fit ​​fixation. One end of the first return spring 303c is fixedly connected to the slanted slider 303b, and the other end of the first return spring 303c is fixedly connected to the side of the sliding groove 303a-1. The wall is fixedly connected; the adjusting component 304 includes a hinged long rod 304a, a connecting column 304b, a second return spring 304c, and a fixing block assembly 304d. The lower end of the hinged long rod 304a is hinged to the side wall of the auxiliary snap-fit ​​block 302b, and the connecting column 304b is fixedly connected to the upper end of the hinged long rod 304a. The second return spring 304c has one end fixedly connected to the hinged long rod 304a and the other end fixedly connected to the auxiliary snap-fit ​​block 302b. The fixing block assembly 304d is fixedly connected to the side of the fixed housing 303a near the auxiliary snap-fit ​​block 302b. The second return spring 304c allows the hinged long rod 304a to swing while keeping it in a vertical state.

[0039] Furthermore, the fixing block assembly 304d includes a first fixing block 304d-1, a second fixing block 304d-2, and a sliding groove 304d-3 formed between the first fixing block 304d-1 and the second fixing block 304d-2. The first fixing block 304d-1 is disposed on the side of the fixing housing 303a near the auxiliary locking block 302b, and the second fixing block 304d-2 is disposed on the side of the fixing housing 303a near the auxiliary locking block 302b, and the second fixing block 304d-2 is disposed above the first fixing block 304d-1. The sliding groove 304d-3 cooperates with the connecting post 304b of the adjusting member 304, and the connecting post 304b slides within the sliding groove 304d-3. -3 is used to provide a locking point for the snap-fit ​​fixed state. The height of the port where the connecting post 304b enters the sliding groove 304d-3 is different from the height of the port where it slides out of the sliding groove 304d-3, so that the adjusting member 304 cooperates with the rotating member 301. When the shorter end of the abutting rod 301b presses against the protective top frame 101d, it drives the connecting post 304b to enter from the lower port of the sliding groove 304d-3. At this time, the auxiliary plug-in member 202 and the auxiliary snap-fit ​​member 303 are snapped together. When the longer end of the abutting rod 301b presses against the protective top frame 101d, it drives the connecting post 304b to exit from the higher port of the sliding groove 304d-3. At this time, the auxiliary plug-in member 202 and the auxiliary snap-fit ​​member 303 can be released simultaneously.

[0040] The rest of the structure is the same as in Example 1.

[0041] Operation process: The gate body 101 is installed at the dam reservoir for water discharge and flood discharge when necessary. The sand discharge port 101a on the gate body 101 is used to clean and discharge silt from the bottom of the dam reservoir during normal water storage. The rotating component 301 drives the hinged long rod 304a to rotate 180 degrees. When the end of the abutting rod 301b, which is closer to the motor 301a, abuts against the protective top frame 101d, it presses the protective top frame 101d towards the mounting base along the sliding rod 101c until the first insert 201 and the first snap-fit ​​302 engage and fix it. The auxiliary insert 202 and the auxiliary snap-fit ​​303 also engage and fix it, thus securing the protective base frame 101b and the protective top frame 101d. The locking mechanism, with the cooperation of the adjusting component 304 and the tension spring 101f, locks the fixed locking state of the protective base frame 101b and the protective top frame 101d. This prevents the protective base frame 101b and the protective top frame 101d from being loosely fixed, which could cause fish to accidentally enter the sand discharge outlet 101a and become extinct, thus affecting the protective effect. Similarly, by rotating the set rotating component 301 by 180 degrees, the end of the abutting rod 301b, which is farther away from the motor 301a, abuts against the protective top frame 101d, thereby releasing the fixed locking state of the protective base frame 101b and the protective top frame 101d. This improves the sand discharge effect and solves the problem that the sand discharge outlet 101a of the sand discharge gate lacks protection, which can easily cause the extinction of some migratory fish and damage the ecological environment of the dam reservoir.

[0042] Example 3 Reference Figures 1-12 This embodiment differs from the previous embodiments in that the control component 400 includes a hydraulic rod 401 disposed in the sand discharge port 101a, a first transmission member 402 movably connected to the hydraulic rod 401, and a sealing member 403 movably connected to the first transmission member 402. The rear end of the hydraulic rod 401 is fixedly connected to the side wall of the mounting frame. The hydraulic rod 401 provides power to the first transmission member 402. The movement of the first transmission member 402 drives the sealing member 403 to open or close the sand discharge port 101a.

[0043] Furthermore, the unblocking component 500 includes a power component 501 disposed within the mounting bracket, a second transmission component 502 movably connected to the power component 501, and a sliding component 503 movably connected to the second transmission component 502. The movement of the power component 501 drives the movement of the second transmission component 502, and the movement of the second transmission component 502 drives the sliding component 503 to clean the blockage in the sand discharge port 101a, preventing silt and other blockages from settling and accumulating in the sand discharge port 101a for too long, causing blockage, or preventing silt from blocking the sand discharge port 101a during sand discharge, resulting in poor sand discharge. The second transmission component 502 is movably connected to the first transmission component 402. When the first transmission component 402 drives the sealing component 403 to open or close the sand discharge port 101a, the first transmission component 402 drives the first transmission component 402 to slide, which can adjust the cleaning distance of the sliding component 503.

[0044] Furthermore, the first transmission component 402 includes a rotating disk 402a and a fixed disk 402b. The rotating disk 402a is movably connected to the hydraulic rod 401 and is hinged to the mounting frame. The fixed disk 402b is fixedly connected to the mounting frame, and a first sliding hole 101e groove is provided on the fixed disk 402b. The rotating disk 402a includes a rotating disc 402a-1, a toggle rod 402a-2, an anti-blocking slide plate 402a-3, and a connecting slider 402a-4. The rotating disc 402a-1 is hinged to the mounting frame and can rotate within the mounting frame. -1 is provided with a second sliding hole 101e groove. The actuating rod 402a-2 is fixedly connected to the rotating disk 402a-1. The end of the hydraulic rod 401 is hinged to the actuating rod 402a-2. The anti-blocking slide plate 402a-3 is fixedly connected to the actuating rod 402a-2 and is slidably connected to the mounting bracket. The anti-blocking slide plate 402a-3 is used to protect the first transmission component 402 when the actuating rod 402a-2 moves, so as to prevent silt and other substances from entering and affecting the use effect. The connecting slider 402a-4 is fixedly connected to the end of the actuating rod 402a-2 away from the rotating disk 402a-1.

[0045] Furthermore, the sealing element 403 includes a sealing block 403a, a sealing elastic block 403b, a sealing slide 403c, and a connecting slide post 403d. Multiple sealing blocks 403a are provided and slidably connected to the mounting bracket. The sealing elastic block 403b is fixedly connected to the outer side of the sealing block 403a. The sealing slide 403c is fixedly connected to the end of the sealing block 403a near the fixed plate 402b and slidably connected to the mounting bracket. The sealing slide 403c is used to prevent silt and other contaminants from entering the first sliding hole 101e groove and the second sliding hole 101e groove, thus affecting the operation of the mechanism. The outer side of the sealing elastic block 403b, which abuts against the sealing end, is arc-shaped. This achieves a better sealing effect and avoids the impact of silt and other residues on the sealing effect. The connecting slide 403d is fixedly connected to the side wall of the sealing block 403a, and the connecting slide 403d passes through the first sliding hole 101e groove on the fixed disk 402b and the second sliding hole 101e groove on the rotating disk 402a-1. When the rotating disk 402a rotates, the connecting slide 403d is driven to move through the second sliding hole 101e groove of the rotating disk 402a-1 and the first sliding hole 101e groove of the fixed disk 402b.

The second transmission component 502 also includes an arc-shaped connecting plate 502e. Two arc-shaped connecting plates 502e are provided. The arc-shaped connecting plates 502e are fixedly connected to both sides of the fixed slide rod 501a. An arc-shaped slide groove 502e-1 is provided on the arc-shaped connecting plate 502e. The arc-shaped slide groove 502e-1 is adapted to the connecting slider 402a-4. When the actuating rod 402a-2 of the first transmission component 402 moves, the connecting slider 402a-4 on the actuating rod 402a-2 and the arc-shaped slide groove 502e-1 on the arc-shaped connecting plate 502e drive the power component 501 to slide, thereby adjusting the swing amplitude of the rotating ring 502b.

[0048] Furthermore, the sliding member 503 includes a sliding block 503a, a sliding punch 503b, and a spherical hinged long rod 503c304a.

The spherical hinged long rod 503c304a allows the sliding punch 503b to move within the rotating ring 502b. Driven by 2b, it slides along the direction of the sliding hole 503a-1, and makes the sliding cleaning effect of the sliding punch 503b better. The sliding punch 503b includes a sliding round rod 503b-1 and a sharp punch 503b-2. The sliding round rod 503b-1 is slidably connected to the sliding hole 503a-1. One end of the sliding round rod 503b-1 is hinged to the spherical hinged long rod 503c304a. The other end of the sliding round rod 503b-1 is fixedly connected to the sharp punch 503b-2. The sharp punch 503b-2 can agitate the silt deposited near the sand discharge port 101a to prevent the sand discharge port 101a from being blocked and affecting the sand discharge effect.

[0049] The rest of the structure is the same as in Example 2.

[0050] Operation Process: By setting the control component 400 and the unblocking component 500 at the sand discharge port 101a, the silt at the bottom of the dam reservoir is discharged when necessary. Activating the hydraulic rod 401 drives the first transmission component 402, which in turn drives the sealing component 403 to open or close the sand discharge port 101a, or adjust the opening size of the sand discharge port 101a as needed. After the sand discharge port 101a is open, the power component 501 moves, which drives the second transmission component 502, which in turn drives the sliding component 503 to clear the blockage at the sand discharge port 101a. When the first transmission component 402 drives the sealing component 403 to open or close the sand discharge port 101a, the larger the opening of the sealing component 403 to the sand discharge port 101a, the more the first transmission component 402 drives the second transmission component 502 to move, making the cleaning distance of the sliding component 503 larger and passing through the sealing component 403. When the sealing component 403 closes the sand discharge port 101a, the cleaning distance of the sliding component 503 is the smallest and it is located inside the sealing component 403, which makes it easier for the sealing component 403 to close the sand discharge port 101a. This solves the problem that the sand discharge port 101a of the dam reservoir is easy to be blocked and that the opening size of the sand discharge port 101a is difficult to adjust.
