Description

Technical Field

[0001] The invention relates to the technical field of scour prevention, and in particular to an underwater pier scour prevention device and a use method thereof. Background Art

[0002] Local scouring of bridge piers is an important cause of bridge damage. The direct economic losses caused by bridge damage due to floods during the flood season are as high as tens of billions of yuan, and are increasing year by year.

[0003] In order to reduce the scouring of water on bridge piers, it is necessary to provide protection around the bridge piers. Generally, most of the existing anti-scouring methods achieve the anti-scouring effect by throwing a large number of stones around the bridge piers. However, due to the large size of the bridge piers, the amount of work required to throw stones around them is very large, and it also takes a long time to build. In addition, it is necessary to perform precise calculations and throw stones around the bridge piers to form an effective protective layer, which not only requires a large amount of materials and equipment, but also requires a long construction time. In addition, since the protection is formed by stacking stones, the stones may be displaced or rolled under the long-term scouring of water, and their integrity is relatively poor, which can easily lead to damage or failure of the protective layer.

[0017] Furthermore, an underwater bridge pier anti-scouring device and an underwater bridge pier anti-scouring method include the following steps:

[0018] S1: First, after the pier is built, the device is placed on the outer surface of the pier, so that it sinks into the water. When the pier is washed by seawater, the flowing water will impact the surface of the guide plate. After the guide plate is impacted, it will drive the gear shaft to rotate on the limit plate.

[0019] S2: When the gear shaft rotates, it will drive the push-pull rod to rotate back and forth. When the push-pull rod rotates back and forth, it will pull the connecting plate to make the round shaft rotate back and forth inside the square block;

[0020] S3: When the circular shaft rotates, it drives the swing plate to rotate through the hollow sleeve. When the hollow sleeve drives the swing plate to rotate, it squeezes through the L rod and the protrusion at the bottom of the square block. When the hollow sleeve rotates, the L rod squeezes the swing plate, causing the L rod to deflect. When the swing plate deflects with the rotation of the hollow sleeve, it can guide the water flow to the side of the pier, thereby reducing the scouring of the pier by the water flow.

[0021] The present invention has the following beneficial effects:

[0022] 1. The present invention, firstly, after the bridge pier is built, the device is put on the outer surface of the bridge pier to make it sink underwater. Then, when the bridge pier is washed by seawater, the flowing water will impact the surface of the guide plate. After the guide plate is impacted, it will drive the gear shaft to rotate on the limit plate. Since the gear shaft and the push-pull rod are eccentrically arranged, when the guide plate drives the gear shaft to rotate, the eccentric rod will rotate inside the circular groove on the limit plate. When the gear shaft rotates, it will drive the push-pull rod to rotate back and forth. When the push-pull rod rotates back and forth, it will pull the connecting plate to make the circular shaft rotate in the square. The inside of the square block rotates back and forth, and when the circular shaft rotates, it drives the swing plate to rotate through the hollow sleeve. When the hollow sleeve drives the swing plate to rotate, it squeezes through the L rod and the protrusion at the bottom of the square block. When the hollow sleeve rotates, the L rod squeezes the swing plate, which causes the L rod to drive the swing plate to deflect. When the swing plate deflects with the rotation of the hollow sleeve, the water flow can be guided to the side of the pier to prevent the water flow from directly impacting the front of the pier. Compared with the traditional method, this can significantly reduce the risk of scouring, improve the stability of the pier, and improve the anti-scouring effect.

[0023] 2. According to the present invention, when water flows through the device, the flow generated will make the floating ring shake, and the limit of the disc can make the floating ring drive the connecting rod to move up and down inside the disc, and the floating ring can also move up and down according to the change of water level, so that the guide mechanism can adjust the up and down height according to the real-time water flow conditions. When the connecting rod moves upward, it will first move the special-shaped plate up a certain distance, and then the special-shaped plate will push the circular sleeve to make the rotating mechanism move up. When the special-shaped plate moves up this distance first, the moving special-shaped plate will drive the gear to rotate in the C-shaped frame through the teeth. When the C-shaped frame rotates, it will drive the swing plate 2 to deflect, so that the deflected swing plate 2 passes through the circular sleeve. It contacts the surface of the pier, and when the gear rotates, it will also drive the convex plate to rotate, and when the convex plate rotates, it will drive the telescopic plate to move forward, and when the telescopic plate moves forward, it will fit against the surface of the pier, and can provide additional support when the connecting rod moves up and down, reduce the shaking amplitude of the rotating mechanism, thereby improving the stability of the entire device, and help ensure that the rotating mechanism and the guide mechanism always remain in an effective position to minimize the scouring of the pier by the water flow, and when the connecting rod moves with the rotating mechanism and the guide mechanism as the water level changes, the guide mechanism can be more flexibly adapted to the changes in the water flow, and can more effectively disperse and guide the water flow, thereby reducing the scouring force on the pier.

[0024] 3. In the present invention, when the water flow hits the guide plate and causes it to rotate, the rotating guide plate will rotate with the gear shaft, and the rotation of the multiple gear shafts will drive the gear ring to rotate. When the gear ring rotates, the top of the gear ring can be inserted into the protrusion in the arc groove inside the rotating sleeve, and the rotating sleeve can rotate between the two arc support plates. When the rotating sleeve rotates, the cam on the rotating sleeve will squeeze the square frame, so that the square frame drives the piston plate to slide in the piston cylinder. When the piston cylinder slides, the staggered one-way plates inside the two F tubes will form an open state, and when the piston plate moves, the F tube at the bottom can be used to Water is pumped into the piston cylinder, and then when the piston plate returns to its original position, it will squeeze the water and enter the water outlet ring. At this time, the water entering through multiple piston cylinders can be sprayed out through the water outlet ring. At this time, the sprayed water flow will form convection with the water flow guided and dispersed by the guide mechanism. The formed convection can disperse the water flow flowing from the bottom of the pier, and can reduce the water flow with too fast a velocity flowing through the bottom surface of the pier, thereby taking away the mud and sand at the bottom of the pier. The uninterrupted water spraying of this device can slow down the loss of mud and sand, and reduce the impact of long-term mud and sand loss on the stress state of the pier.

[0025] 4. According to the present invention, when the square frame pushes the square frame to move forward in the piston cylinder, a part of the water in the piston cylinder can be squeezed into the outer cylinder through the water inlet pipe. At this time, the one-way plate 2 can prevent the internal water from flowing back. At this time, the water entering the interior will lift the movable column to make it move upward in the outer cylinder. When the movable column moves upward, the reciprocating mechanism will drive the T-plate to rotate in the fixed plate. When the T-plate rotates, the side plates will squeeze the movable plate. After being squeezed, the movable plate will push the sliding rod to move downward in the hollow plate. When the sliding rod moves downward in the hollow plate, the arc-shaped baffle plate at the bottom of the sliding rod will be inserted into the mud and sand at the bottom of the water bottom. The insertion of multiple arc-shaped baffle plates can enhance the stability of the device when it is washed by water flow. At the same time, a circular cylinder can be formed on the outside of the pier, which can reduce the loss of mud and sand around the pier and between the sliding rod, thereby further enhancing the stability of the device and the pier when the water flow washes the pier.

[0054] An underwater bridge pier anti-scouring device and an underwater bridge pier anti-scouring method include the following steps:

[0055] S1: First, after the pier is built, the device is placed on the outer surface of the pier, so that the pier is sunk into the water. When the pier is washed by seawater, the flowing water will impact the surface of the guide plate 206. After the guide plate 206 is impacted, it will drive the gear shaft 204 to rotate on the limit plate 203;

[0056] S2: When the gear shaft 204 rotates, it pulls the push-pull rod 301 to rotate back and forth. When the push-pull rod 301 rotates back and forth, it pulls the connecting plate 302 to make the round shaft 303 rotate back and forth inside the square block 304;

[0057] S3: When the circular shaft 303 rotates, the swing plate 306 is driven to rotate through the hollow sleeve 305. When the hollow sleeve 305 drives the swing plate 306 to rotate, it is squeezed through the L rod 308 and the protrusion at the bottom of the square block 304. When the hollow sleeve 305 rotates, the L rod 308 is squeezed, which causes the swing plate 306 to deflect. When the swing plate 306 deflects with the rotation of the hollow sleeve 305, the water flow can be guided to the side of the bridge pier, thereby reducing the scouring of the bridge pier by the water flow.

[0058] When in use, first after the pier is built, the device is put on the outer surface of the pier to make it sink underwater. Then, when the pier is washed by sea water, the flowing water will impact the surface of the guide plate 206. After the impact, the guide plate 206 will drive the gear shaft 204 to rotate on the limit plate 203. Since the gear shaft 204 and the push-pull rod 301 are eccentrically arranged, when the guide plate 206 drives the gear shaft 204 to rotate, the eccentric rod 207 will rotate inside the circular groove on the limit plate 203. When the gear shaft 204 rotates, it will pull the push-pull rod 301 to rotate back and forth. When the push-pull rod 301 rotates back and forth, it will pull the connecting plate 302 to make the circular shaft 303 rotate. The inside of the square block 304 rotates back and forth, and when the circular shaft 303 rotates, it drives the swing plate 306 to rotate through the hollow sleeve 305. When the hollow sleeve 305 drives the swing plate 306 to rotate, it squeezes the L rod 308 and the protrusion at the bottom of the square block 304. When the hollow sleeve 305 rotates, the L rod 308 squeezes the swing plate 306, which causes the L rod 308 to drive the swing plate 306 to deflect. When the swing plate 306 deflects with the rotation of the hollow sleeve 305, it can guide the water flow to the side of the pier to prevent the water flow from directly impacting the front of the pier. Compared with the traditional method, this can significantly reduce the risk of scouring, improve the stability of the pier, and improve the anti-scouring effect. Afterwards, when the water flow flushes the device, the flow generated will cause the floating ring 402 to shake, and the limit of the disc 101 can make the floating ring 402 drive the connecting rod 401 to move up and down inside the disc 101, and the floating ring 402 can also move up and down according to the change of water level, so that the guide mechanism 3 can adjust the up and down height according to the real-time water flow situation. When the connecting rod 401 moves upward, it will first move the special-shaped plate 403 up a distance, and then the special-shaped plate 403 will push the circular sleeve 201 to move the rotating mechanism 2 up. When the special-shaped plate 403 moves up this distance first, the moving special-shaped plate 403 will drive the gear 404 to rotate in the C-shaped frame 405 through the teeth. When the C-shaped frame 405 rotates, it will drive the swing plate 2 406 to deflect, so that the swing after deflection The second plate 406 passes through the circular sleeve 201 and contacts the surface of the bridge pier, and when the gear 404 rotates, it also drives the convex plate 408 to rotate, and when the convex plate 408 rotates, it drives the telescopic plate 409 to move forward, and when the telescopic plate 409 moves forward, it will fit the surface of the bridge pier, which can provide additional support when the connecting rod 401 moves up and down, reduce the shaking amplitude of the rotating mechanism 2, thereby improving the stability of the entire device, and help ensure that the rotating mechanism 2 and the guide mechanism 3 always remain in an effective position to minimize the scouring of the bridge pier by the water flow, and when the connecting rod 401 moves with the rotating mechanism 2 and the guide mechanism 3 as the water level changes, the guide mechanism 3 can be more flexibly adapted to the changes in the water flow, and the water flow can be more effectively dispersed and guided, thereby reducing the scouring force on the bridge pier.

[0059] When the water flow hits the guide plate 206 and causes it to rotate, the rotating guide plate 206 will rotate with the gear shaft 204, and the rotation of the multiple gear shafts 204 will drive the gear ring 501 to rotate. When the gear ring 501 rotates, the top of the gear ring 501 can be inserted into the protrusion in the arc groove inside the rotating sleeve 503, and the rotating sleeve 503 can rotate between the two arc support plates 502. When the rotating sleeve 503 rotates, the cam on the rotating sleeve 503 will squeeze the square frame 601, so that the square frame 601 drives the piston plate 602 to slide in the piston cylinder 603. When the piston cylinder 603 slides, the staggered one-way plates 605 inside the two F tubes 604 will form an open state, and the piston When the plate 602 moves, water can be pumped into the piston cylinder 603 through the F tube 604 at the bottom. Then, when the piston plate 602 returns to its original position, the water will be squeezed to make the water enter the water outlet ring 606. At this time, the water entering through the multiple piston cylinders 603 can be sprayed out through the water outlet ring 606. At this time, the sprayed water flow will form convection with the water flow guided and dispersed by the guide mechanism 3. The formed convection can disperse the water flow flowing from the bottom of the pier, and can reduce the water flow with too fast a flow rate from flowing through the bottom surface of the pier to take away the mud and sand at the bottom of the pier. The uninterrupted water spraying of this device can slow down the loss of mud and sand, and reduce the influence of long-term mud and sand loss on the stress state of the pier. When the square frame 601 pushes the square frame 601 to move forward in the piston cylinder 603, a part of the water in the piston cylinder 603 can be squeezed into the outer cylinder 708 through the water inlet pipe 709. At this time, the one-way plate 710 can prevent the water in 608 from flowing back. At this time, the water entering the interior of 608 will lift the moving column 707 to move upward in the outer cylinder 708. When the moving column 707 moves upward, it will drive the T-shaped plate 703 to rotate in the fixed plate 701 through the 70 reciprocating mechanism 6. When the T-shaped plate 703 rotates, it will contact the movable plate 703 through the side plates. The plate 704 is squeezed, and the movable plate 704 pushes the sliding rod 705 to move downward in the hollow plate 702 after being squeezed. When the sliding rod 705 moves downward in the hollow plate 702, the arc-shaped baffle plate at the bottom of the sliding rod 705 is inserted into the mud at the bottom of the water, and the insertion of multiple arc-shaped baffle plates can enhance the stability of this device when being washed by water flow. At the same time, a circular cylinder can be formed outside the pier, which can reduce the loss of mud and sand around the pier and between the sliding rod 705, thereby further enhancing the stability of this device and the pier when the water flow washes the pier.
