[0036] When splicing the cofferdam, first arrange multiple bases 1, flip plates 2 and spoiler plates 3 according to the terrain and the shape of the cofferdam required during use. After the arrangement is completed, the bottom plate 11 placed in the correct position is fixed, and then the dual-axis waterproof motor 16 is started. The output end of the dual-axis waterproof motor 16 drives the two conical teeth 18 to rotate. When the two conical teeth 18 rotate, they engage with the two second conical teeth 19, thereby driving the two screw rods 17 to rotate on the inner walls of the two guide plates 15. When the two screw rods 17 rotate, they drive the two transmission blocks 112 to slide back and forth on the inner walls of the two guide plates 15. When the two transmission blocks 112 slide, they drive the two L-shaped rotating rods 111 to rotate through the L-shaped rotating rod connecting rod 110. At the same time, the two transmission blocks 112 drive the two rotating rods 113 to rotate. When the two rotating rods 113 move, they drive the inverted U-shaped slide plate 115 to slide on the inner wall of the slide groove opened at the bottom of the flip plate body 21. At this time, the flip plate 2 is pushed to flip by the sliding of the inverted U-shaped slide plate 115. And support, so that the flip plate 2 is flipped with the flip connecting plate 12 as the axis until the flip plate 2 is flipped to a horizontal state, completing the splicing of the flip plate 2. At this time, start the motor 26, and the output end of the motor 26 drives the turntable 27 to rotate. When the turntable 27 rotates, it drives the crawler 28 to move. When the crawler 28 moves, it drives the second turntable 29 to rotate. When the second turntable 29 rotates, it drives the columnar rotating rod 319 to rotate. When the columnar rotating rod 319 rotates, it drives the elliptical rotating block 316 to rotate. When the elliptical rotating block 316 rotates, it drives the two retracting and expanding rotating rods 317 to rotate. When the two retracting and expanding rotating rods 317 rotate, they drive the two retracting and expanding connecting blocks 318 to move relative to or away from each other. When the two retracting and expanding connecting blocks 318 move, they drive the retracting and expanding push-pull plate 322 and the spoiler bottom plate retracting and expanding push-pull plate 3310 to move relative to or away from each other. When the retracting and expanding push-pull plate 322 moves, it drives the spoiler top plate 32 to move. When the spoiler bottom plate retracting and expanding push-pull plate 3310 moves, it drives the spoiler bottom plate 33 to move.

[0037] When the spoiler top plate main board 321 moves toward the top, the inner sides of the two groups of clamping blocks 3211 move to the outer walls of the two positioning blocks 25. At this time, since the spoiler bottom plate main body 331 moves toward the bottom, the two telescopic rod connecting blocks 334 pull the two telescopic rods 335 and the pulling blocks 336 toward the bottom, and then the two pulling blocks 336 drive the two triangular block push-pull rods 3212 to move toward the bottom. When the two triangular block push-pull rods 3212 move, they drive the two triangular block 3213 to slide on the inner sides of the two groups of triangular moving blocks 3210. The two triangular block 321 When sliding toward the bottom, the two sets of triangular moving blocks 3210 are moved inward by the elastic force of the two sets of springs 329. At the same time, the two sets of triangular moving blocks 3210 drive the two sets of clamping blocks 3211 to move inward until the inner sides of the two sets of clamping blocks 3211 are tightly fitted against the outer walls of the two positioning blocks 25. At this time, the spoiler top plate 32 and the spoiler bottom plate 33 are adjusted to a suitable spacing by the relative movement or opposite movement of the expansion and contraction push-pull plate 322 and the expansion and contraction push-pull plate 3310, respectively. The splicing of the spoiler 3 is completed by the tight fit between the two sets of clamping blocks 3211 and the two positioning blocks 25.

[0038] When the spoiler bottom plate body 331 moves toward the bottom, the multiple stabilizing drills 333 on the stabilizing drill control plate 332 contact the ground and drill into the soil, increasing the stability of the spoiler bottom plate body 331 and preventing it from sliding or displacing during use. As the spoiler bottom plate body 331 continues to move downward, the telescopic rod 335 gradually extends, and the pull block 336 and the pull block connecting block 337 also move downward, further enhancing the structural stability of the entire spoiler 3. At the same time, the fit between the spoiler top plate sub-plate 325 and the spoiler bottom plate body 331 is tighter, effectively blocking the water flow and ensuring the waterproof performance of the cofferdam. Then, the cofferdam structure is formed by splicing and combining the base 1, the flip plate 2 and the spoiler 3, thereby achieving the purpose of detachable splicing cofferdam.

[0039] The working principle of the present invention is as follows: when splicing the cofferdam, firstly, a plurality of bases 1, flip plates 2 and spoiler plates 3 are arranged according to the terrain and the shape of the cofferdam required for use. After the arrangement is completed, the bottom plate 11 placed in the correct position is fixed, and then the dual-axis waterproof motor 16 is started. The output end of the dual-axis waterproof motor 16 drives the two conical teeth 18 to rotate. When the two conical teeth 18 rotate, they engage with the two second conical teeth 19, thereby driving the two screw rods 17 to rotate on the inner walls of the two guide plates 15. When the two screw rods 17 rotate, they drive the two transmission blocks 112 to slide back and forth on the inner walls of the two guide plates 15. When the two transmission blocks 112 slide, they drive the two L-shaped rotating rods 111 to rotate through the L-shaped rotating rod connecting rod 110. When the two rotating rods 113 move, the two rotating rods 113 drive the inverted U-shaped slide plate 115 to slide on the inner wall of the slide groove opened at the bottom of the flip plate body 21. At this time, the flip plate 2 is pushed and flipped and supported by the sliding of the inverted U-shaped slide plate 115, so that the flip plate 2 is flipped with the flip connecting plate 12 as the axis until the flip plate 2 is flipped to a horizontal state, completing the splicing of the flip plate 2. At this time, the motor 26 is started, and the output end of the motor 26 drives the turntable 27 to rotate. When the turntable 27 rotates, it drives the crawler 28 to move. When the crawler 28 moves, it drives the second turntable 29 to rotate. When the second turntable 29 rotates, it drives the columnar rotating rod 319 to rotate. When the rotating rod 319 rotates, it drives the elliptical rotating block 316 to rotate. When the elliptical rotating block 316 rotates, it drives the two contraction and expansion rotating rods 317 to rotate. When the two contraction and expansion rotating rods 317 rotate, they drive the two contraction and expansion connecting blocks 318 to move relative to each other or move away from each other. When the two contraction and expansion connecting blocks 318 move, they drive the contraction and expansion push-pull plate 322 and the spoiler bottom plate contraction and expansion push-pull plate 3310 to move relative to each other or move away from each other. When the contraction and expansion push-pull plate 322 moves, it drives the spoiler top plate 32 to move. When the spoiler bottom plate contraction and expansion push-pull plate 3310 moves, it drives the spoiler bottom plate 33 to move. When the spoiler top plate main board 321 moves toward the top, the inner sides of the two groups of clamping blocks 3211 move to the outer walls of the two positioning blocks 25. At this time, due to the spoiler bottom plate The main body 331 moves toward the bottom, and then the two telescopic rod connecting blocks 334 pull the two telescopic rods 335 and the pulling blocks 336 toward the bottom, and then the two pulling blocks 336 drive the two triangular block push-pull rods 3212 to move toward the bottom. When the two triangular block push-pull rods 3212 move, they drive the two triangular block 3213 to slide on the inner sides of the two groups of triangular moving blocks 3210. When the two triangular block 3213 slide toward the bottom, the two groups of triangular moving blocks 3210 are moved inward by the elastic force of the two groups of springs 329. At the same time, the two groups of triangular moving blocks 3210 drive the two groups of clamping blocks 3211 to move inward until the inner sides of the two groups of clamping blocks 3211 are tightly fitted against the outer walls of the two positioning blocks 25. At this time,The top spoiler plate 32 and bottom spoiler plate 33 are adjusted to an appropriate spacing by moving the retractable and expandable push-pull plate 322 and the bottom spoiler plate retractable and expandable push-pull plate 3310 relative to or away from each other. The two sets of clamping blocks 3211 are tightly fitted with the two positioning blocks 25 to complete the splicing of the spoiler 3. As the bottom spoiler plate body 331 moves toward the bottom, the multiple stabilizer drills 333 on the stabilizer drill control plate 332 contact the ground and drill into the soil.
