This patent can select multiple pile bodies and water-stopping components to adapt to the width of the waterway to be blocked. Since its structure is not fixed and is an assemblable structure, it can be reused, shortening the preparation time before engineering construction, and the energy dissipation device increases the service life of the device, so that the economic cost of the engineering construction unit is reduced.

[0012] According to the above technical scheme, the stabilizing device includes a loading frame, a hollow circular tube, a Z-shaped sheet, a support rod, a collision plate, a hollow frame and a blocking sheet. The deformed Z-shaped sheet recovers under the action of its own elasticity, and the recovery of the Z-shaped sheet drives the hollow circular tube to move upward, and the movement of the hollow circular tube drives the support rod to move upward. The loading frame is fixedly passed through the bottom of the mounting plate, and the hollow circular tube is slidably installed on the inner wall of the loading frame. The Z-shaped sheet is arranged between the hollow circular tube and the loading frame, and the support rod is fixedly installed on the bottom of the hollow circular tube, and the collision plate is fixedly installed on the circumferential surface of the support rod.

[0014] The present invention provides a water stopping device for water conservancy project construction. It has the following beneficial effects:

[0015] (1) In the water-stopping device for water conservancy project construction, the contact block contacts the inner wall of the slot, so that the rectangular plate limits the movement of the lifting cylinder. By pushing the handle to move in the C-shaped slot, the staff can quickly unfold the rectangular plate to adapt to the width of the river channel under standardized operation, which helps to improve the applicability of the rectangular plate in water-stopping work. The No. 2 spring applies thrust to the rectangular plate, and the movement of the rectangular plate drives the movement of the counter plate. The kinetic energy is increased when the No. 2 spring is restored, which effectively improves the efficiency of the deployment of the rectangular plate, and then slows down the initial velocity of the No. 2 spring when it is reset, which helps to improve the safety of the staff in water-stopping preparation work.

[0016] (2) In the water conservancy project construction water-stopping device, the carrying plate moves upward and separates from the river channel, so that when the rectangular plate is unfolded, the carrying plate does not contact the river channel to increase friction resistance. By automatically retracting the carrying plate, the resistance generated by the friction between the carrying plate and the river channel is prevented from affecting the deployment efficiency. Then, pressure is applied to the carrying plate to ensure that the carrying plate and the river channel are stably fitted together for water stopping. The limit plate contacts the inner wall of the limit groove, so that the rectangular plate limits the movement of the lifting plate. By limiting the lifting plate, it is ensured that the carrying plate will not separate from the side in contact with the river channel in the process of use, which effectively improves the stability and controllability of water stopping.

[0017] (3) In the water-stopping device of the water conservancy project construction, the support rod is moved and inserted into the mud, so that the mud exerts a supporting force on the support rod. The support rod is inserted into the mud to improve the impact resistance of the carrying plate, so as to avoid the inability of the carrying plate to effectively stop water after being unfolded. Then, a hollow circular tube is used to enable the staff to actively pull out the stuck support rod. The collision plate transmits the vibration to the support rod through resonance, so that the support rod vibrates continuously during the movement. The vibration is generated by the intermittent collision between the collision plate and the blocking plate, which helps to reduce the adhesion of the soil, making it easier for the support rod to enter the mud and improving the smoothness of the construction.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 9, one embodiment of the present invention is: a water-stopping device for water conservancy engineering construction, comprising a water-stopping plate 1, a loading tube 2 is fixedly installed on the outer wall of the water-stopping plate 1, a ground pile 3 is slidably installed on the inner wall of the loading tube 2, a rectangular groove is provided inside the water-stopping plate 1, a C-shaped groove is provided on the inner wall of the rectangular groove, and a stretching device is also included; wherein the stretching device comprises a rectangular plate 4, a lifting cylinder 5, a gripping rod 6, a first spring 7, a contact block 8, a pushing plate 9, a second spring 10, a rubber plate 11 and a stop plate 12, the rectangular plate 4 is slidably installed inside the rectangular groove, the lifting cylinder 5 is slidably installed inside the rectangular plate 4, the gripping rod 6 slides through one end of the lifting cylinder 5 close to the C-shaped groove, the first spring 7 is arranged between the gripping rod 6 and the lifting cylinder 5, and the contact block 8 is fixedly installed on the gripping rod 6 The contact block 8 slides through the outer wall of the lifting cylinder 5, the pushing plate 9 slides through the side of the rectangular plate 4 close to the water stop plate 1, the No. 2 spring 10 is arranged between the pushing plate 9 and the rectangular plate 4, the rubber plate 11 is fixedly installed on the circumferential surface of the pushing plate 9, the stop plate 12 is fixedly installed on the inner wall of the rectangular plate 4 close to the rubber plate 11, and a sliding groove is provided on the side of the rectangular plate 4 close to the C-shaped groove, the lifting cylinder 5 contacts the inner wall of the sliding groove, the lifting cylinder 5 contacts the inner wall of the C-shaped groove, and the side of the pushing plate 9 away from the No. 2 spring 10 contacts the inner wall of the water stop plate 1, and the operator can quickly unfold the rectangular plate 4 to adapt to the width of the river channel by pushing the handle 6 to move in a standardized manner in the C-shaped groove, which helps to improve the applicability of the rectangular plate 4 during water stopping work.

[0030] A slot is provided on the inner wall of the slide, and the contact block 8 contacts the inner wall of the slot. An arc surface is provided on the bottom of the contact block 8. A limiting slot is provided on one side of the rectangular plate 4 close to the slot. The contact block 8 contacts the slot, so that the rectangular plate 4 limits the movement of the lifting cylinder 5, ensuring that the position of the lifting cylinder 5 will not change due to accidental touch during the water stopping process, thereby ensuring that the unfolded rectangular plate 4 can be stably maintained in the predetermined position.

[0031] A corrugation 1 is provided on one side of the rubber plate 11 close to the abutment plate 12, and the corrugation 1 is in contact with the abutment plate 12. A slope 1 is provided on one side of the abutment plate 12 close to the rubber plate 11. By applying a thrust to the rectangular plate 4, the deployment efficiency of the rectangular plate 4 is improved. At the same time, the contact between the corrugation 1 and the abutment plate 12 slows down the speed of the No. 2 spring 10 when it is just reset, which helps to improve the safety of the staff in the water-stopping preparation work.

[0032] When the present embodiment is working, the water stop plate 1 is placed inside the river channel, and the ground piles 3 are driven into the mud so that the mud supports the water stop plate 1, pushing the gripping rod 6 to move in the direction of the lifting cylinder 5. The gripping rod 6 squeezes the No. 1 spring 7 during the movement, and the No. 1 spring 7 is deformed by the squeezing. At the same time, the movement of the gripping rod 6 drives the contact block 8 to move in the direction of the lifting cylinder 5. The contact block 8 separates from the side in contact with the slot during the movement, so that the limit imposed by the rectangular plate 4 on the movement of the lifting cylinder 5 is released. First, the gripping rod 6 is pushed upward to the highest point of the slide slot. The movement of the gripping rod 6 drives the lifting cylinder 5 and the contact block 8 to move upward, and then the gripping rod 6 is pushed to move in the direction away from the water stop plate 1. The lifting cylinder 5 and the contact block 8 move in a direction away from the water stop plate 1. The lifting cylinder 5 moves while driving the rectangular plate 4 to move in a direction away from the water stop plate 1. Finally, the grip 6 is pushed downward to the lowest point of the slide slot. The grip 6 moves and drives the lifting cylinder 5 and the contact block 8 to move downward. After the grip 6 moves to the specified position, the grip 6 is released. The squeezed No. 1 spring 7 recovers under the action of its own elasticity. The recovery of the No. 1 spring 7 drives the grip 6 to move in a direction away from the lifting cylinder 5. The grip 6 moves and drives the contact block 8 to move in a direction away from the lifting cylinder 5. The contact block 8 contacts the inner wall of the slot during the movement, so that The rectangular plate 4 limits the movement of the lifting cylinder 5, and by pushing the handle 6 to move in the C-shaped groove, the operator can unfold the rectangular plate 4 to adapt to the width of the river channel under standardized operation, which helps to improve the stability of the water-stopping work. When the lifting cylinder 5 moves to the highest point of the C-shaped groove, the squeezed No. 2 spring 10 recovers under the action of its own elasticity. Since the pushing plate 9 contacts the inner wall of the water-stop plate 1, the pushing plate 9 is blocked by the water-stop plate 1 and cannot move away from the No. 2 spring 10, so that the No. 2 spring 10 applies a thrust to the rectangular plate 4 during the recovery process, and the rectangular plate 4 is affected by the thrust and moves away from the water-stop plate 1. The movement of the rectangular plate 4 drives the push plate 12 to move away from the push plate 9. The movement of the push plate 12 generates friction with the corrugation 1, so that the movement speed of the push plate 12 is slowed down by the friction force. The push plate 12 continues to move and separates from the side in contact with the corrugation 1, so that the inclined surface 1 of the push plate 12 is in contact with the corrugation 1. The pressure applied by the rubber plate 11 to the push plate 12 through the corrugation 1 is gradually reduced, so that the resistance encountered by the push plate 12 when moving is gradually reduced, and the No. 2 spring 10 is used to apply a thrust to the rectangular plate 4, which improves the deployment efficiency while slowing down the speed of the No. 2 spring 10 when it is just reset, thereby improving the safety of the staff in the water-stopping preparation work.

[0033] See also Figure 1-Figure 9On the basis of the above embodiment, another embodiment of the present invention further includes a leak-proof device and a stabilizing device; the leak-proof device includes a lifting plate 131, a No. 3 spring 132, a carrying plate 133, a No. 1 spring 134, a squeezing plate 135, a limiting plate 136 and a No. 2 spring 137, the lifting plate 131 slides through the bottom of the rectangular plate 4, the No. 3 spring 132 is arranged between the lifting plate 131 and the rectangular plate 4, the carrying plate 133 is slidably installed at the bottom of the lifting plate 131, and the No. 1 spring 134 is fixedly installed at the lifting plate 131 At the bottom, the extrusion plate 135 is fixedly installed on the end of the No. 1 spring piece 134 away from the lifting plate 131, the limiting plate 136 slides through the side of the lifting plate 131 close to the limiting groove, and the No. 2 spring piece 137 is arranged between the limiting plate 136 and the lifting plate 131. When the top of the lifting plate 131 contacts the curved surface, the carrying plate 133 is folded when the rectangular plate 4 is unfolded to avoid the resistance generated by the friction between the carrying plate 133 and the river channel affecting the unfolding efficiency, and then pressure is applied to the carrying plate 133 to ensure that the carrying plate 133 is stably fitted with the river channel to stop water.

[0034] The size of the limiting plate 136 is adapted to the limiting groove, the carrying plate 133 contacts the inner wall of the rectangular plate 4, a circular hole is provided at the bottom of the carrying plate 133, and a groove is provided at the bottom of the extrusion plate 135. By automatically limiting the lifting plate 131, it is ensured that the carrying plate 133 will not be separated from the side in contact with the river channel in an unexpected situation during use, which helps to improve the stability and controllability of water stopping.

[0035] A second arc surface is provided on one side of the limit plate 136 away from the second spring piece 137, and the second arc surface contacts the inner wall of the rectangular plate 4. By providing the second arc surface on the limit plate 136, the friction between the limit plate 136 and the rectangular plate 4 when moving is effectively reduced, thereby extending the service life of the limit plate 136.

[0036] The stabilizing device includes a loading frame 141, a hollow circular tube 142, a Z-shaped sheet 143, a support rod 144, a collision plate 145, a hollow frame 146 and a blocking sheet 147. The loading frame 141 is fixedly installed at the bottom of the mounting plate 133, the hollow circular tube 142 is slidably installed on the inner wall of the loading frame 141, the Z-shaped sheet 143 is arranged between the hollow circular tube 142 and the loading frame 141, the support rod 144 is fixedly installed at the bottom of the hollow circular tube 142, and the collision plate 145 is fixedly installed at the bottom of the hollow circular tube 142. Installed on the circumferential surface of the support rod 144, the hollow frame 146 is fixedly passed through the top of the inner wall of the mounting plate 133, the blocking piece 147 is fixedly installed on the inner wall of the hollow frame 146, the hollow circular tube 142 is in contact with the inner wall of the groove, the Z-shaped piece 143 is elastic, and a conical surface is provided at the bottom of the support rod 144. The support rod 144 is inserted into the mud to improve the impact resistance of the mounting plate 133, and then the hollow circular tube 142 is used to enable the staff to actively pull out the stuck support rod 144.

[0037] The top of the blocking piece 147 is provided with an arc surface 3, and the blocking piece 147 is elastic. Vibration is generated through intermittent collision between the collision plate 145 and the blocking piece 147, which helps to reduce the adhesion of the soil when the support rod 144 is inserted into the mud, making it easier for the support rod 144 to enter the mud and improving the smoothness of the construction.

[0038] When the present embodiment is working, the arc surface of the contact block 8 gradually reduces the pressure applied to the lifting plate 131 as it moves upward, so that the deformed No. 3 spring 132 recovers and drives the lifting plate 131 to move upward, and the movement of the lifting plate 131 drives the carrying plate 133 to move upward, and the carrying plate 133 moves upward to separate from the side in contact with the river channel, so that when the rectangular plate 4 is unfolded, the carrying plate 133 does not contact the river channel to increase the friction resistance, and at the same time, the unfolding of the rectangular plate 4 drives the lifting plate 131 to move away from the water stop plate 1, and the movement of the lifting plate 131 drives the carrying plate 133 to move away from the water stop plate 1, and after the carrying plate 133 moves to the predetermined position, the arc surface of the contact block 8 moves downward to apply pressure to the lifting plate 131 The lifting plate 131 is under the influence of the pressure and moves downward. The lifting plate 131 stretches the No. 3 spring 132 during the movement. The No. 3 spring 132 is stretched and deformed. At the same time, the lifting plate 131 moves and drives the carrying plate 133 to move downward. The carrying plate 133 contacts the bottom of the river channel during the movement. The carrying plate 133 is blocked by the river channel and stops moving. The lifting plate 131 continues to move and drives the No. 1 spring piece 134 to move downward. The No. 1 spring piece 134 moves and drives the extrusion plate 135 to move downward. The extrusion plate 135 contacts the bottom of the inner wall of the carrying plate 133 during the movement. The extrusion plate 135 is blocked by the carrying plate 133 and stops moving, so that the lifting plate 131 moves During the process, the spring sheet 134 is squeezed, and the spring sheet 134 is squeezed and deformed. The deformed spring sheet 134 exerts a downward reaction force on the squeezing plate 135 under the action of its own elasticity. The squeezing plate 135 is affected by the reaction force and exerts downward pressure on the carrying plate 133. The carrying plate 133 is affected by the pressure and fits tightly with the river channel. By automatically retracting the carrying plate 133, the resistance generated by the friction between the carrying plate 133 and the river channel is avoided to affect the deployment efficiency. Then, pressure is applied to the carrying plate 133 to ensure that the carrying plate 133 is stably fitted with the river channel to stop water. The lifting plate 131 moves downward and drives the limit plate 136 to move downward. The arc surface 2 of the limit plate 136 and the river channel are in the process of movement. The inner wall of the rectangular plate 4 is separated, so that the deformed No. 2 spring piece 137 is restored under the action of its own elasticity. The No. 2 spring piece 137 applies a thrust to the limit plate 136 during the restoration process. The limit plate 136 is affected by the thrust and moves away from the lifting plate 131. The limit plate 136 contacts the inner wall of the limit groove during the movement, so that the rectangular plate 4 limits the movement of the lifting plate 131. The lifting plate 131 is limited and cannot move, resulting in the stretched No. 3 spring 132 being unable to restore. By limiting the lifting plate 131, it is ensured that the carrying plate 133 will not be separated from the side in contact with the river channel in an unexpected situation during use, which effectively improves the stability and controllability of water stopping.

[0039] The groove of the extrusion plate 135 moves downward to apply downward pressure to the hollow circular tube 142. The hollow circular tube 142 moves downward under the influence of the pressure. The hollow circular tube 142 squeezes the Z-shaped sheet 143 during the movement. The Z-shaped sheet 143 is squeezed and deformed. At the same time, the movement of the hollow circular tube 142 drives the support rod 144 to move downward. The conical surface of the support rod 144 passes through the circular hole and contacts the bottom of the river during the movement. The support rod 144 continues to move and is inserted into the mud, so that the mud applies a supporting force to the support rod 144, and the support rod 144 transmits the obtained supporting force to the hollow frame 146. The hollow frame 146 transmits the supporting force to the carrying plate 133, effectively improving the ability of the carrying plate 133 to withstand the impact of water flow. After the application is completed, the squeezing plate 135 returns to its original position, and the pressure applied to the hollow circular tube 142 gradually decreases, so that the deformed Z-shaped piece 143 recovers under the action of its own elasticity. The recovery of the Z-shaped piece 143 drives the hollow circular tube 142 to move upward, and the movement of the hollow circular tube 142 drives the support rod 144 to move upward. The conical surface of the support rod 144 is pulled out of the mud during the movement. When the support rod 144 is stuck due to an emergency, the staff can use a round rod to penetrate it. The support rod 144 is inserted into the mud to improve the impact resistance of the carrying plate 133, and the hollow tube 142 is used to enable the staff to actively pull out the stuck support rod 144. The support rod 144 moves while driving the collision plate 145 to move downward. The collision plate 145 contacts and collides with the arc surface three during the movement, so that the collision plate 145 continues to move and exerts downward pressure on the arc surface three. The blocking sheet 147 is deformed by the pressure, and the deformed blocking sheet 147 bends downward to collide with the arc surface three. The collision plate 145 continues to move and separates from the side in contact with the arc surface three, so that the pressure exerted by the collision plate 145 on the arc surface three is gradually reduced, and the blocking piece 147 recovers under the action of its own elasticity. At the same time, the collision plate 145 intermittently collides with the arc surface three during the movement to vibrate, and the collision plate 145 transmits the vibration to the support rod 144 through resonance, so that the support rod 144 vibrates continuously during the movement. The vibration generated by the intermittent collision between the collision plate 145 and the blocking piece 147 helps to reduce the adhesion of the soil, making it easier for the support rod 144 to enter the mud, thereby improving the smoothness of the construction.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
