Description

Technical Field

[0001] The present invention relates to the technical field of gate structures, and specifically to a gate structure for water conservancy projects and its usage method. Background Art

[0002] The gate for water conservancy projects is a key device for controlling water flow, regulating water level, and managing water body flow. It is widely used in water conservancy facilities such as dams, reservoirs, and rivers, and is mainly used for functions such as flood prevention, water flow regulation, and irrigation.

[0003] The patent with the patent announcement number CN220503823U relates to a gate structure for water conservancy projects, including a concrete water channel. An installation frame is fixedly installed on the concrete water channel; a hydraulic cylinder is fixedly installed on the installation frame, and a gate adapted to the concrete water channel is fixedly installed on the driving rod of the hydraulic cylinder. A through port is opened inside the gate, and a filtering mechanism adapted to the inclination of the concrete water channel is arranged inside the through port. A liquid discharge port is opened on the gate, and the amount of water passing through is adjusted by the movement of the filtering mechanism. A fishing mechanism for fishing debris when the gate moves upward is arranged at the bottom of the water-facing surface of the gate. This patent proposes a gate structure for water conservancy projects. By providing a filtering mechanism and a fishing mechanism, when the gate moves upward, it self-adapts to the inner wall of the concrete water channel to fish out floating objects, which is beneficial to the timely opening of the gate and increases the convenience of cleaning floating objects.

[0004] In the above patent, it has the effect of facilitating the timely opening of the gate. By setting a filtering mechanism and a fishing mechanism, when the gate moves upward, floating objects are fished out, which is beneficial to the timely opening of the gate and increases the convenience of cleaning floating objects. However, during the process of fishing debris, since the opening of the gate will accelerate the flow of water, the floating objects collected by the filtering mechanism are washed away by the water flow, and the fishing mechanism needs to be operated repeatedly, increasing the complexity and time cost of the fishing process and reducing the efficiency of the entire cleaning process. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a gate structure for water conservancy projects and its usage method, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A gate structure for a water conservancy project, including a concrete water channel, a support frame is fixedly installed on the top of the concrete water channel, a driving mechanism is arranged on the top of the support frame, and a closing door is fixedly installed at the output end of the driving mechanism. When the driving mechanism is started, the output end of the driving mechanism drives the closing door to move upward, and the surface of the closing door in contact with the concrete water channel during the movement is separated.

A debris removal device is also included; wherein, the debris removal device includes a fishing plate, a push rod, a first spring, a limiting rod, a rotating shaft, a rotating plate, a gear, a connecting frame, a T-shaped plate, a second spring and a number of tooth blocks. When the T-shaped plate moves, the pulling force applied to the second spring gradually decreases, so that the deformed second spring restores and drives the T-shaped plate to move downward. The fishing plate is slidably installed on the surface of the loading plate, the push rod slidably penetrates the inner and outer walls of the fishing plate, the first spring is arranged between the push rod and the fishing plate, the limiting rod is fixedly installed on the side of the push rod close to the limiting groove, the rotating shaft rotatably penetrates the inner and outer walls of the fishing plate, the rotating plate is fixedly installed on the circumferential surface of the rotating shaft, the gear is fixedly installed on the circumferential surface of the rotating shaft, the connecting frame fixedly penetrates the top of the fishing plate, the T-shaped plate is slidably installed on the inner wall of the connecting frame, the second spring is arranged between the T-shaped plate and the fishing plate, and a number of the tooth blocks are fixedly installed on the side of the T-shaped plate close to the gear. A first hole groove is opened on the surface of the fishing plate, the T-shaped plate slidably penetrates the inner and outer walls of the fishing plate, the movement of the loading plate drives the fishing plate to move upward, the movement of the fishing plate drives the connecting frame to move upward, the movement of the connecting frame drives the T-shaped plate to move upward, and the gear meshes with the tooth blocks.

[0007] According to the above technical solution, the limiting rod slidably penetrates the side of the fishing plate close to the limiting groove, the circumferential surface of the limiting rod is in contact with the inner wall of the limiting groove, and the surface of the limiting rod in contact with the limiting groove during the movement is separated, so that the limit applied by the loading plate to the fishing plate is released. The rotating plate is in contact with the closing door, a rectangular groove is opened on the side of the rotating plate close to the closing door, and a second hole groove is opened on the surface of the rotating plate. When the fishing plate and the rotating plate move to the water surface, the water inside the fishing plate and the rotating plate is discharged through the first hole groove and the second hole groove.

[0008] According to the above technical solution, a first scroll spring is arranged between the rotating shaft and the fishing plate. When the rotating shaft rotates, the deformed scroll spring restores to provide additional power for the rotation of the rotating shaft. The bottom of the T-shaped plate is in contact with the concrete water channel.

[0009] According to the above technical solution, the protection device includes a carrying frame, a lifting rod, a third spring, a collar, a contact block, a portal frame, a rotating rod, an arc-shaped piece and a comb-shaped plate. The movement of the lifting rod drives the collar to move downward, the movement of the collar drives the contact block to move downward, and at the same time, the movement of the collar drives the portal frame to move downward. The carrying frame is fixedly installed on the surface of the connection frame. The lifting rod slides through the inner and outer walls of the carrying frame. The third spring is arranged between the lifting rod and the carrying frame. The collar is fixedly installed on the circumferential surface of the lifting rod. The contact block is fixedly installed on the circumferential surface of the collar. The portal frame is fixedly installed on the circumferential surface of the collar. The rotating rod rotates through the circumferential surface of the portal frame. The arc-shaped piece is fixedly installed on the circumferential surface of the rotating rod. The comb-shaped plate is fixedly installed on the inner wall of the carrying frame. The bottom of the lifting rod contacts the top of the T-shaped plate. When the second spring drives the T-shaped plate to move downward, the supporting force exerted by the T-shaped plate on the lifting rod gradually decreases, causing the deformed third spring to start to recover. A second scroll spring is arranged between the rotating rod and the portal frame. The rotating rod stretches the second scroll spring during rotation, and the second scroll spring deforms under the stretching force.

[0010] According to the above technical solution, a first arc surface is provided on one side of the portal frame close to the arc-shaped piece. The first arc surface contacts the curved surface of the arc-shaped piece. When the comb-shaped plate moves, it exerts a pressure on the curved surface of the arc-shaped piece, and the arc-shaped piece rotates downward under the influence of the pressure. The arc-shaped piece separates from the first arc surface during rotation. An arc surface two is provided on the side of the contact block away from the collar.

[0011] According to the above technical solution, the stabilizing device includes a fixing plate, a rubber plate, a telescopic rod, a fourth spring, a linkage piece, a clamping block, a elastic piece and a clamping plate. The deformed fourth spring exerts a thrust on the rubber plate under the action of its own elasticity. The rubber plate is in close contact with the concrete water channel under the influence of the thrust. The fixing plate fixedly penetrates the inner and outer walls of the loading plate. The rubber plate slides through the side of the fixing plate close to the concrete water channel. The telescopic rod slides through the inner and outer walls of the fixing plate.

The arc surface three contacts the arc surface two. When the linkage piece moves downward and contacts the contact block, the arc surface two exerts a pressure on the moving arc surface three, and the linkage piece moves toward the rubber plate under the influence of the pressure. The rubber plate contacts the concrete water channel.

[0012] According to the above technical solution, anti-slip grooves are provided on the surface of the rubber plate close to the concrete water channel. An arc surface four is provided at the top of the clamping block. The arc surface four of the clamping block contacts the inclined surface one of the clamping plate during movement. The inclined surface one applies resistance to the moving arc surface four, and the clamping block moves towards the telescopic rod under the influence of the resistance. The inclined surface one is provided at the bottom of the clamping plate.

[0013] According to the above technical solution, clamping grooves are provided on the surface of the clamping plate. The inner wall of the clamping groove contacts the clamping block. The restored deformed elastic sheet drives the clamping block to move upward. The clamping block contacts the inner wall of the clamping groove during movement, causing the No. 4 spring to remain in a deformed state.

[0014] A method for using a gate of a gate structure for a water conservancy project. Using the above-mentioned gate structure for a water conservancy project, the method includes the following steps:

[0015] Step 1: When it is necessary to open the closing door, start the driving mechanism. The output end of the driving mechanism drives the closing door to move upward, and the surface of the closing door in contact with the concrete water channel separates.

[0016] Step 2: The movement of the closing door drives the loading plate to move upward. The movement of the loading plate drives the fishing plate to move upward. The movement of the fishing plate drives the collected foreign objects to move upward.

[0017] Step 3: The rotating plate moves towards the fishing plate. After the rotating plate rotates to a predetermined position, it stops rotating. The rotating plate contacts the inner wall of the fishing plate, so that the rotating plate presses the collected foreign objects.

[0018] Step 4: When the rotating plate moves out of the water surface, it collects the foreign objects floating on the water surface. When the fishing plate moves to the water surface, the water inside the fishing plate and the rotating plate is discharged through the first hole groove and the second hole groove. The operator collects and processes the collected foreign objects.

[0019] The present invention provides a gate structure for a water conservancy project, which has the following beneficial effects:

[0020] (1) For this gate structure for a water conservancy project, the limiting rod and the limiting groove are separated, so that the limiting effect exerted by the loading plate on the fishing plate is released. By setting the No. 1 spring, it is ensured that the limiting rod stably contacts the limiting groove, avoiding potential safety hazards caused by limiting failure. At the same time, it is convenient for the operator to quickly disassemble the fishing plate, improving the work efficiency. At the same time, the rotating plate contacts the inner wall of the fishing plate, and the rotating plate presses the collected foreign objects. By applying pressure to the foreign objects in the fishing plate through the rotating plate, it prevents the foreign objects from being carried away when the water flows rapidly, improving the collection effect and avoiding blockage, ensuring smooth water flow after the closing door is opened.

[0021] (2) For the gate structure used in this water conservancy project, the intermittent collision between the arc-shaped sheet and the comb-shaped plate generates continuous vibrations. The vibrations generated by the collision are transmitted to the T-shaped plate through the comb-shaped plate, reducing the obstruction of underwater foreign objects to the movement of the T-shaped plate and preventing the problem of movement jamming caused by external foreign objects or resistance. Thus, the stability and smoothness of the movement of the T-shaped plate are improved. At the same time, when the comb-shaped plate and the arc-shaped sheet are in surface contact, the arc-shaped sheet rotates downward to resolve the collision. During the closing process of the closing gate, unnecessary collisions between the arc-shaped sheet and the comb-shaped plate are reduced, effectively improving the accuracy of vibration release, and thus reducing the wear between the arc-shaped sheet and the comb-shaped plate.

[0022] (3) For the gate structure used in this water conservancy project, the deformed No. 4 spring exerts a thrust on the rubber plate, and the rubber plate is in close contact with the concrete water channel. When the closing gate is closed, the force exerted by the No. 4 spring ensures the close contact between the rubber plate and the concrete water channel, which helps to improve the stability of the closing gate underwater. The fixture block contacts the inner wall of the card slot during movement, keeping the No. 4 spring in a deformed state. Through the contact between the second arc surface and the third arc surface, the fixture block automatically limits the telescopic rod, and the limiting effect of the fixture block is used to improve the stability of the contact between the rubber plate and the concrete water channel, thereby improving the practicality of the rubber plate.

[0035] The limiting rod 9 slides through the surface of the fishing plate 6 close to the limiting groove. The circumferential surface of the limiting rod 9 contacts the inner wall of the limiting groove. The rotating plate 11 contacts the closing door 4. A rectangular groove is formed on the surface of the rotating plate 11 close to the closing door 4, and a second hole groove is formed on the surface of the rotating plate 11. By providing the first spring 8, it is ensured that the limiting rod 9 stably contacts the limiting groove, avoiding potential safety hazards caused by ineffective limiting.

[0036] A first volute spring is provided between the rotating shaft 10 and the fishing plate 6. The bottom of the T-shaped plate 14 contacts the concrete water channel 1. By providing the first volute spring, the burden when the gear block 16 drives the gear 12 to rotate is reduced, ensuring that the rotating plate 11 can smoothly rotate to the designated position.

[0037] A method for using a gate of a gate structure for a water conservancy project, using the above-mentioned gate structure for a water conservancy project, includes the following steps:

[0038] Step 1: When it is necessary to open the closing door 4, start the driving mechanism 3. The output end of the driving mechanism 3 drives the closing door 4 to move upward, and the surface of the closing door 4 in contact with the concrete water channel 1 is separated.

[0039] Step 2: The movement of the closing door 4 drives the loading plate 5 to move upward. The movement of the loading plate 5 drives the fishing plate 6 to move upward. The movement of the fishing plate 6 drives the collected foreign objects to move upward.

[0040] Step 3: The rotating plate 11 moves towards the fishing plate 6. After the rotating plate 11 rotates to the predetermined position, it stops rotating. The rotating plate 11 contacts the inner wall of the fishing plate 6, so that the rotating plate 11 presses the collected foreign objects.

[0041] Step 4: When the rotating plate 11 moves out of the water surface, it collects the foreign objects floating on the water surface. When the fishing plate 6 moves to the water surface, the water inside the fishing plate 6 and the rotating plate 11 is discharged through the first hole groove and the second hole groove. The operator collects and processes the collected foreign objects.

[0042] During the operation of this embodiment, the driving mechanism 3 is started, and the output end of the driving mechanism 3 drives the closing door 4 to move upward. The surface of the closing door 4 in contact with the concrete water channel 1 is separated during the movement. At the same time, the movement of the closing door 4 drives the loading plate 5 to move upward, the movement of the loading plate 5 drives the fishing plate 6 to move upward, the movement of the fishing plate 6 drives the collected foreign objects to move upward, and at the same time, the movement of the fishing plate 6 drives the connecting frame 13 to move upward, the movement of the connecting frame 13 drives the T-shaped plate 14 to move upward, and the surface of the T-shaped plate 14 in contact with the concrete water channel 1 is separated during the movement. At the same time, the pulling force applied by the T-shaped plate 14 to the second spring 15 gradually decreases, so that the deformed second spring 15 returns to its original state and drives the T-shaped plate 14 to move downward. The movement of the T-shaped plate 14 drives the tooth block 16 to move downward, the movement of the tooth block 16 drives the gear 12 to rotate in the direction of the T-shaped plate 14, the rotation of the gear 12 drives the rotating shaft 10 to rotate in the direction of the T-shaped plate 14, and the rotation of the rotating shaft 10 drives the rotating plate 11 to rotate in the direction away from the closing door 4. After the rotating plate 11 rotates to a predetermined position, it stops rotating. The rotating plate 11 contacts the inner wall of the fishing plate 6, so that the rotating plate 11 presses the collected foreign objects. While the rotating shaft 10 rotates, the deformed scroll spring returns to its original state to provide additional power for the rotation of the rotating shaft 10. When the rotating plate 11 moves out of the water surface, the rectangular groove of the rotating plate 11 collects the foreign objects floating on the water surface. When the fishing plate 6 and the rotating plate 11 move to the water surface, the water inside the fishing plate 6 and the rotating plate 11 is discharged through the first hole groove and the second hole groove. The operator first collects and processes the foreign objects in the rectangular groove, and then opens the rotating plate 11 to collect and process the foreign objects in the fishing plate 6. By applying pressure to the foreign objects in the fishing plate 6 through the rotating plate 11, it is possible to prevent the foreign objects from being carried away when the water flows rapidly, improve the collection effect, and avoid blockage, ensuring smooth water flow after the closing door 4 is opened. When it is necessary to disassemble the fishing plate 6 for maintenance, push the push rod 7 to move in the direction away from the loading plate 5. The push rod 7 squeezes the first spring 8 during the movement, and the first spring 8 deforms under the extrusion. At the same time, the movement of the push rod 7 drives the limit rod 9 to move in the direction of the first spring 8, and the surface of the limit rod 9 in contact with the limit groove is separated, so that the limit applied by the loading plate 5 to the fishing plate 6 is released. Pull the push rod 7 to move in the direction away from the closing door 4. The movement of the push rod 7 drives the fishing plate 6 to move in the direction away from the closing door 4. The movement of the fishing plate 6 drives the rotating shaft 10 to move in the direction away from the closing door 4. The movement of the rotating shaft 10 drives the rotating plate 11 to move in the direction away from the closing door 4. When the fishing plate 6 moves to a specified position, the surface in contact with the loading plate 5 is separated. After the cleaning is completed, then perform standard operations to fix the fishing plate 6 on the loading plate 5 for use. By setting the first spring 8, it is ensured that the limit rod 9 is stably in contact with the limit groove, avoiding potential safety hazards caused by limit failure, and at the same time facilitating the operator to quickly disassemble the fishing plate 6 and improving the work efficiency.

[0043] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, it further includes a protection device and a stabilizing device; the protection device includes a carrying frame 171, a lifting rod 172, a third spring 173, a collar 174, a contact block 175, a portal frame 176, a rotating rod 177, an arc-shaped piece 178 and a comb-shaped plate 179. The carrying frame 171 is fixedly installed on the surface of the connecting frame 13. The lifting rod 172 slides through the inner and outer walls of the carrying frame 171. The third spring 173 is arranged between the lifting rod 172 and the carrying frame 171. The collar 174 is fixedly installed on the circumferential surface of the lifting rod 172. The contact block 175 is fixedly installed on the circumferential surface of the collar 174. The portal frame 176 is fixedly installed on the circumferential surface of the collar 174. The rotating rod 177 rotates through the circumferential surface of the portal frame 176. The arc-shaped piece 178 is fixedly installed on the circumferential surface of the rotating rod 177. The comb-shaped plate 179 is fixedly installed on the inner wall of the carrying frame 171. The bottom of the lifting rod 172 contacts the top of the T-shaped plate 14. A second volute spring is arranged between the rotating rod 177 and the portal frame 176. Vibration is generated by the intermittent collision between the arc-shaped piece 178 and the comb-shaped plate 179, which helps to prevent the movement jamming problem caused by external foreign objects or resistance, thereby improving the stability and smoothness of the movement of the T-shaped plate 14.

[0044] An arc surface one is opened on one side of the portal frame 176 close to the arc-shaped piece 178. The arc surface one contacts the curved surface of the arc-shaped piece 178. An arc surface two is opened on one side of the contact block 175 away from the collar 174. During the closing process of the closing door 4, the arc-shaped piece 178 and the comb-shaped plate 179 do not collide, effectively improving the accuracy of vibration release.

[0045] The stabilizing device includes a fixing plate 181, a rubber plate 182, a telescopic rod 183, a fourth spring 184, a linkage piece 185, a clamping block 186, a spring piece 187 and a clamping plate 188. The fixing plate 181 fixedly penetrates through the inner and outer walls of the loading plate 5. The rubber plate 182 slides through the inner and outer walls of the fixing plate 181 on the side close to the concrete water channel 1. The telescopic rod 183 slides through the inner and outer walls of the fixing plate 181. The fourth spring 184 is arranged between the telescopic rod 183 and the rubber plate 182. The linkage piece 185 is fixedly installed on the side of the telescopic rod 183 away from the rubber plate 182. The clamping block 186 slides through the circumferential surface of the telescopic rod 183. The spring piece 187 is arranged between the clamping block 186 and the telescopic rod 183. The clamping plate 188 is fixedly installed on the side of the fixing plate 181 close to the clamping block 186. An arc surface three is opened on the side of the linkage piece 185 away from the telescopic rod 183. The arc surface three contacts the arc surface two. The rubber plate 182 contacts the concrete water channel 1. By the contact between the arc surface two and the arc surface three, the clamping block 186 automatically applies a limit to the telescopic rod 183, effectively improving the convenience of use, thereby improving the practicality of the rubber plate 182.

[0046] The side of the rubber plate 182 close to the concrete water channel 1 is provided with anti-slip grooves, the top of the clamping block 186 is provided with a fourth arc surface, and the bottom of the clamping plate 188 is provided with a first inclined surface. By providing the anti-slip grooves, the friction between the rubber plate 182 and the concrete water channel 1 is increased, thereby improving the use effect of the rubber plate 182.

[0047] The surface of the clamping plate 188 is provided with a clamping groove, and the inner wall of the clamping groove is in contact with the clamping block 186. Through the force exerted by the deformation of the fourth spring 184 and the limiting effect of the clamping block 186, it is ensured that the contact between the rubber plate 182 and the concrete water channel 1 remains tight and stable.

[0048] When the second spring 15 drives the T-shaped plate 14 to move downward during the operation of this embodiment, the supporting force exerted by the T-shaped plate 14 on the lifting rod 172 gradually decreases, causing the deformed third spring 173 to start to recover. The recovery of the third spring 173 drives the lifting rod 172 to move downward. The movement of the lifting rod 172 drives the collar 174 to move downward. The movement of the collar 174 drives the contact block 175 to move downward. At the same time, the movement of the collar 174 drives the portal frame 176 to move downward. The movement of the portal frame 176 drives the rotating rod 177 to move downward. The movement of the rotating rod 177 drives the arc-shaped piece 178 to move downward. The concave surface of the arc-shaped piece 178 contacts the comb-shaped plate 179 during the movement. The comb-shaped plate 179 exerts a resistance on the arc-shaped piece 178. The arc-shaped piece 178 continues to move downward and bends upward under the condition of being obstructed. When the surface where the arc-shaped piece 178 contacts the comb-shaped plate 179 separates, the deformed arc-shaped piece 178 quickly recovers under the action of its own elasticity. During the recovery process, the arc-shaped piece 178 recontacts the comb-shaped plate 179 and generates a collision. Then the arc-shaped piece 178 repeats the above movement and intermittently collides with the comb-shaped plate 179 to generate continuous vibration. The comb-shaped plate 179 transmits the vibration to the moving T-shaped plate 14. The movement of the T-shaped plate 14 becomes smoother under the influence of rotation. By generating vibration through the intermittent collision between the arc-shaped piece 178 and the comb-shaped plate 179, it helps to reduce the obstruction of underwater foreign objects to the movement of the T-shaped plate 14 and prevent the problem of movement jamming caused by external foreign objects or resistance, thereby improving the stability and smoothness of the movement of the T-shaped plate 14. When the closing door 4 moves downward to close, the connecting frame 13 moves and drives the carrying frame 171 to move downward. The movement of the carrying frame 171 drives the lifting rod 172 to move downward. At the same time, the connecting frame 13 moves and drives the T-shaped plate 14 to move downward. The T-shaped plate 14 contacts the concrete water channel 1 during the movement. The T-shaped plate 14 is blocked and stops moving, causing the fishing plate 6 to continue to move and stretch the second spring 15. At the same time, the lifting rod 172 continues to move and contacts the top of the T-shaped plate 14. The lifting rod 172 is blocked and stops moving, causing the carrying frame 171 to continue to move and squeeze the third spring 173. The third spring 173 deforms under the extrusion. At the same time, the movement of the carrying frame 171 drives the comb-shaped plate 179 to move downward. The comb-shaped plate 179 contacts the curved surface of the arc-shaped piece 178 during the movement. The movement of the comb-shaped plate 179 exerts a pressure on the curved surface of the arc-shaped piece 178. The arc-shaped piece 178 rotates downward under the influence of the pressure. The arc-shaped piece 178 separates from the first arc surface during the rotation. At the same time, the rotation of the arc-shaped piece 178 drives the rotating rod 177 to rotate downward. The rotating rod 177 stretches the second scroll spring during the rotation. The second scroll spring deforms under the stretch. When the arc-shaped piece 178 separates from the comb-shaped plate 179, the deformed second scroll spring recovers and drives the rotating rod 177 to rotate upward. The rotation of the rotating rod 177 drives the arc-shaped piece 178 to rotate upward. After the arc-shaped piece 178 returns to the initial position, it contacts the first arc surface. During the closing process of the closing door 4, the arc-shaped piece 178 does not collide with the comb-shaped plate 179, effectively improving the accuracy of vibration release.Unnecessary collisions between the arc-shaped piece 178 and the comb-tooth plate 179 are reduced, thereby effectively reducing wear;

[0049] When the closing door 4 is in the closed state, the deformed No. 4 spring 184 applies a thrust to the rubber plate 182 under the action of its own elasticity, and the anti-skid groove of the rubber plate 182 is in close contact with the concrete water channel 1 under the action of the thrust. When the closing door 4 moves upward to open, the loading plate 5 moves to drive the fixing plate 181 to move upward, and the fixing plate 181 moves to drive the rubber plate 182 to move upward. The rubber plate 182 is gradually separated from the concrete water channel 1 during the movement, so that the deformed No. 4 spring 184 recovers and drives the rubber plate 182 to move away from the telescopic rod 183. The rubber plate 182 stops moving after moving to the specified position, so that the recovery of the No. 4 spring 184 is restricted, and the No. 4 spring 184 maintains the deformed state. At the same time, the arc surface 2 of the contact block 175 is in the movement and linkage. The arc surface of the sheet 185 is separated. When the fixed plate 181 moves out of the water, the block 186 is manually pressed to move downward. The block 186 squeezes the spring sheet 187 during the movement. The spring sheet 187 is squeezed and deformed. At the same time, the block 186 is separated from the card slot during the movement, so that the restriction on the deformed No. 4 spring 184 is released. The No. 4 spring 184 recovers and drives the telescopic rod 183 to move away from the rubber plate 182. The movement of the telescopic rod 183 drives the linkage sheet 185 to move away from the rubber plate 182. At the same time, the movement of the telescopic rod 183 drives the block 186 to move away from the rubber plate 182. The surface of the block 186 in contact with the card plate 188 is separated during the movement, so that the deformation spring sheet 187 recovers and drives the block 186 to move upward. The force applied by the spring 184 when deforming and the limiting effect of the block 186 ensure that the contact between the rubber plate 182 and the concrete water channel 1 remains tight and stable, which helps to improve the stability of the closed door 4 underwater. When the closed door 4 moves downward to close, the fixed plate 181 moves to drive the rubber plate 182 to move downward. The rubber plate 182 contacts the concrete water channel 1 during movement. The concrete water channel 1 applies resistance to the rubber plate 182. The rubber plate 182 is affected by the resistance and moves toward the telescopic rod 183. The rubber plate 182 squeezes the fourth spring 184 during movement. At the same time, the linkage piece 185 moves downward and contacts the contact block 175. The arc surface 2 applies resistance to the moving arc surface 3. The linkage piece 185 is affected by the resistance and moves toward the rubber plate 182. The movable piece 185 moves and drives the telescopic rod 183 to move toward the rubber plate 182. The telescopic rod 183 squeezes the deformed No. 4 spring 184 during the movement, so that the thrust exerted by the No. 4 spring 184 on the rubber plate 182 gradually increases. At the same time, the telescopic rod 183 moves and drives the clamping block 186 to move toward the rubber plate 182. The arc surface 4 of the clamping block 186 contacts the inclined surface 1 of the clamping plate 188 during the movement. The inclined surface 1 applies resistance to the moving arc surface 4. The clamping block 186 moves toward the telescopic rod 183 under the influence of the resistance. The clamping block 186 squeezes the spring piece 187 during the movement. The spring piece 187 is squeezed and deformed. When the arc surface 4 moves to the predetermined position, it separates from the contact surface of the clamping plate 188, so that the deformed spring piece 187 recovers and drives the clamping block 186 to move upward.The clamping block 186 contacts the inner wall of the clamping groove during movement, causing the fourth spring 184 to remain deformed. By contacting the second arc surface with the third arc surface, the clamping block 186 automatically applies a limit to the telescopic rod 183, effectively improving the convenience of use, thereby enhancing the practicality of the rubber plate 182.
