[0009] Preferably, the scraper is provided in the shape of two fish fins spliced into one; through the scraper, during the cleaning process of the auxiliary sealing assembly, since the scraper is provided in the shape of two fish fins spliced into one, the shape of the fish fin can help to disperse the pressure of the water flow and provide a balancing force, so that the scraper can maintain a stable rotating state, the problem that the resistance of the water to the auxiliary sealing assembly is large when the auxiliary sealing assembly rotates and affects the rotating state of the auxiliary sealing assembly is solved as much as possible, and the stability of the auxiliary sealing work is improved.

[0010] Preferably, the sliding assembly includes helical teeth disposed at the bottom end of the sliding ring. The helical teeth are evenly arranged circumferentially around the axis of the sliding ring. The bottom end of the helical teeth is meshed with a helical gear. One end of the helical gear is fixedly connected to a first bevel gear set. A first transmission assembly is installed at the top end of the first bevel gear set. Through the provided rotating assembly, before the pressure cap is embedded into the through hole for sealing, the obstructions on the outer wall of the pressure cap need to be removed. The cylinder drives the top plate and the pressure cap to press down. The pressing down of the top plate drives the first transmission assembly to transmit power. The first transmission assembly drives the first bevel gear set to rotate. The rotation of the first bevel gear set drives the helical gear to rotate. The rotation of the helical gear drives the helical teeth to rotate, driving the auxiliary sealing assembly to work and providing rotational force for the auxiliary sealing assembly to reduce obstructions on the outer wall of the pressure cap.

[0011] Preferably, the first transmission assembly includes a rotating rod disposed at the top of the first bevel gear set. The rotating rod is rotatably connected to the inside of the fixed frame, and both fixed frames are provided with rotating rods. The two rotating rods are configured to rotate in the same direction. A protrusion is slidably embedded in the outer wall of the rotating rod, and an annular groove for the protrusion to pass through is formed on the outer wall of the rotating rod. The protrusion is fixedly connected to the top plate. One of the rotating rods is fixedly connected to the first bevel gear set, and the bottom end of the other rotating rod is equipped with a second transmission assembly. Through the first transmission assembly, during the process of the cylinder driving the top plate and the pressure cap to press down, the rotating rod is rotatably connected to the inside of the fixed frame. The pressing down of the top plate drives the protrusion to press down together. The pressing down of the protrusion will abut against the annular groove of the rotating rod, giving the rotating rod a downward force. The rotating rod rotates under the force, converting the downward force into a force that drives the rotating assembly and the second transmission assembly to work, thus providing power to the rotating assembly and the second transmission assembly.

[0012] Preferably, the guiding assembly includes a guide block disposed on one side of the sliding ring. The guide block is fixedly connected to the sliding ring, and the sliding ring is slidably embedded inside the precast base plate. The precast base plate has a guide groove for the guide block to slide inside. The guide groove is designed to be annular, inclined downwards for a short period, and then horizontal. The guide groove is symmetrically opened in opposite directions with the axis of the sliding ring as the center. With the guide assembly, when the rotating assembly drives the auxiliary sealing assembly to work, in order to make the auxiliary sealing assembly fit more closely to the outer wall of the pressure cap, the rotating assembly rotates and drives the auxiliary sealing assembly to rotate. A guide block is connected to one side of the connecting plate inside the auxiliary sealing assembly. Under the guidance of the guide groove, the guide block drives the connecting plate to rotate along the guide groove and press down with the cooperation of the first elastic element, and then rotates stably along the groove of the guide groove to fit with the outer wall of the pressure cap. This avoids the problem of the cylinder driving the top plate and the pressure cap to press down and getting stuck with the auxiliary sealing assembly, which would affect the normal operation of the components and ensure the stable operation of each component.

[0013] Preferably, the fixing assembly includes a fixing plate installed on the inner wall of the through hole. The fixing plate is slidably embedded inside the through hole. The bottom outer wall of the pressure cap has a fixing groove for fixing the fixing plate. Two fixing plates are symmetrically installed. One fixing plate has a first connecting rod fixedly connected to one side, a first rack plate fixedly connected to the top of the first connecting rod, a second transmission assembly installed at the top of the first rack plate, and a second gear meshing with the top of the first rack plate. The other fixing plate has a second connecting rod fixedly connected to one side, a second rack plate fixedly connected to the bottom of the second connecting rod, and the bottom of the second rack plate meshing with the second gear. With the fixing assembly, after the pressure cap and the through hole are completely sealed, the second elastic element and the control assembly cooperate to release the elastic energy stored in the second elastic element during the operation of the second transmission assembly, driving the fixing assembly to fix the pressure cap. This minimizes the problem of the pressure cap being pushed upward by the buoyancy of water after the cylinder is removed, which affects the sealing between the pressure cap and the precast base plate, and improves the stability of the fixing between the pressure cap and the precast base plate.

[0014] Preferably, the second transmission assembly includes a first gear mounted on the top of the first rack plate, the first gear meshing with the first rack plate, a fixed rod fixedly connected to one end of the first gear, a second elastic element sleeved on the outside of the fixed rod, the second elastic element fixedly connected to the first gear, a control assembly mounted on the end of the second elastic element away from the first gear via the fixed rod, a second bevel gear set fixedly connected to the end of the first gear away from the second elastic element, a movable rod fixedly connected inside the end of the second bevel gear set away from the first gear, a locking block fixedly connected to the outer wall of the movable rod, a limiting block sleeved on the outside of the movable rod, a groove for the locking block to slide out of the bottom end of the limiting block, and a fixed connection to the bottom end of the rotating rod; through the configured second transmission assembly, when the first transmission assembly transmits the downward force, the first transmission assembly drives the limiting block to rotate, the limiting block drives the locking block and the movable rod to rotate, the movable rod drives the second bevel gear set to rotate, the second bevel gear set drives the first gear to rotate, and the first gear drives the second elastic element to rotate, providing the second elastic element with elastic energy that can be stored.

[0015] Preferably, the second elastic element is a torsion spring. Through the second elastic element, during the pressing process of the cover, the cylinder drives the top plate and the cover to press down. The pressing down of the top plate drives the second transmission component to transmit power. The second transmission component drives the second elastic element to rotate, generating a torsional force on the second elastic element. When the second elastic element twists, it will be subjected to torsional force, which will cause the second elastic element to deform. During the twisting process, elastic energy is stored and released when needed to provide torsional force, providing power for fixing the fixing component.

[0016] Preferably, the control component includes a movable block disposed at the end of the second elastic element away from the first gear. The movable block is slidably embedded inside the precast base plate. A third elastic element is fixedly connected inside the precast base plate. A top pressure plate is fixedly connected to the top of the third elastic element. A movable rod is attached to the top of the top pressure plate. Through the control component, after the pressure cap is fully inserted into the through hole, the fixing component is controlled to fix the pressure cap. The cylinder drives the top plate and the pressure cap to press down. The top plate presses down on the movable block. The movable block drives the first gear, the second elastic element, the second bevel gear set, the movable rod, the locking block, and the limiting block to press down together, so that the movable rod and the locking block disengage from the groove of the limiting block. Then, with the cooperation of the second transmission component and the second elastic element, the fixing component is fixed to the pressure cap, so that the pressure cap is fully embedded in the through hole as much as possible. After it comes to rest, it is fixed to avoid affecting the fixation of the pressure cap during movement and to ensure the firmness of the fixing component.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, through the provided through holes and pressure caps, water can flow through the through holes in the precast base plate during the installation of the steel-concrete composite caisson. This increases the speed at which water is drained from the bottom of the caisson, thereby reducing the upward buoyancy of the water on the bottom of the precast base plate. This results in a faster sinking speed for the steel-concrete composite caisson, which in turn speeds up the installation of the next layer of caisson wall panels. This avoids the problem that during the installation of the bottom caisson, the larger contact area between the bottom of the caisson and the water results in greater buoyancy and a slower sinking speed, leading to a longer waiting time for the installation of the upper caisson and lower overall installation efficiency. This invention improves the installation speed of the steel-concrete composite caisson.

[0019] 2. In this invention, through the auxiliary sealing component, after the steel-concrete composite caisson is installed, during the process of the pressure cover pressing down to seal the precast base plate, it is necessary to reduce the obstruction between the pressure cover and the through hole. The cylinder drives the top plate and the pressure cover to press down. The pressing down of the top plate drives the first transmission component to transmit power. The first transmission component drives the rotating component, which in turn drives the sliding ring to rotate. The sliding ring drives the connecting plate and the scraper to rotate together, clearing away the obstructions on the outer wall of the pressure cover that affect the seal, so as to make the seal between the pressure cover and the through hole better, minimize the obstructions between the pressure cover and the through hole, and improve the sealing effect.

[0020] 3. In this invention, the scraper is designed to be two fish fins joined together during the cleaning process of the auxiliary sealing component. The shape of the fish fins helps to disperse the pressure of the water flow and provides a balancing force, so that the scraper can maintain a stable rotation state. This minimizes the problem of water resistance affecting the rotation state of the auxiliary sealing component when it rotates, and improves the stability of the auxiliary sealing operation.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figure 1 and Figure 2 The figure shows an anti-buoyancy device for the installation of an auxiliary steel-concrete composite caisson, including a precast base plate 1, a steel protective sleeve 5 installed on the top of the precast base plate 1, a wall panel 2 installed on the top of the precast base plate 1, a C-shaped locking slot provided at the connection of the wall panel 2, an I-beam inserted into the C-shaped locking slot, the wall panels 2 are connected by the I-beam and the C-shaped locking slot, an inner support frame 4 is installed on the inner wall of the wall panel 2, and a connector 3 is installed on the outer wall of the wall panel 2;

[0036] The precast base plate 1 has a through hole inside, and a pressure cover 9 is installed above the through hole. A top plate 8 is fixedly connected to the top of the pressure cover 9. Fixing brackets 6 are slidably connected to both ends of the top plate 8. The friction between the top plate 8 and the fixing brackets 6 is relatively large. Both fixing brackets 6 are fixedly connected to the top of the precast base plate 1. A cylinder 7 is detachably installed on the top of the fixing brackets 6. An auxiliary sealing component is installed on the outer wall of the pressure cover 9, and a fixing component for fixing the pressure cover 9 is installed on the inner wall of the through hole.

[0037] In this implementation plan: through the through holes and pressure caps 9, during the installation of the steel-concrete composite caisson, water can flow through the through holes in the precast base plate 1, increasing the speed at which water is drained from the bottom of the steel-concrete composite caisson. This reduces the upward buoyancy of the water on the bottom of the precast base plate 1, allowing the steel-concrete composite caisson to sink faster. Consequently, the installation speed of the next layer of steel-concrete composite caisson wall panels 2 is also increased. This avoids the problem that during the installation of the steel-concrete composite caisson, the bottom of the caisson needs to sink, resulting in a larger contact area with water, greater buoyancy, and a slower sinking speed. This also leads to a longer waiting time for the installation of the upper layer of steel-concrete composite caisson, resulting in low overall installation efficiency. This improves the installation speed of the steel-concrete composite caisson.

[0038] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The auxiliary sealing assembly shown in the figure includes a scraper 10 disposed on the outer wall of the pressure cover 9. The scraper 10 is slidably connected to the pressure cover 9. A connecting plate 11 is fixedly connected to one side of the scraper 10. A sliding ring 13 is installed at the bottom end of the connecting plate 11. A first elastic element 12 is fixedly connected between the connecting plate 11 and the sliding ring 13. The connecting plate 11 and the sliding ring 13 are elastically connected through the first elastic element 12. A sliding component is installed at the bottom end of the sliding ring 13. A guide component is installed on one side of the sliding ring 13.

[0039] In this embodiment: After the steel-concrete composite caisson is installed, during the process of the pressure cover 9 pressing down to seal the precast base plate 1, it is necessary to reduce the obstruction between the pressure cover 9 and the through hole. The cylinder 7 drives the top plate 8 and the pressure cover 9 to press down. The pressing down of the top plate 8 drives the first transmission component to transmit power. The first transmission component drives the rotating component, which in turn drives the sliding ring 13 to rotate. The sliding ring 13 drives the connecting plate 11 and the scraper 10 to rotate together, clearing away the obstructions on the outer wall of the pressure cover 9 that affect the seal, so that the seal between the pressure cover 9 and the through hole is better, minimizing the obstructions between the pressure cover 9 and the through hole that affect the seal between the pressure cover 9 and the through hole, and improving the sealing effect.

[0040] Example 2

[0041] Please see Figure 4 This embodiment further illustrates Example 1, in which the scraper 10 is shown in the figure as two fish fin-shaped parts joined together.

[0042] In this embodiment: During the cleaning process of the auxiliary sealing component, the scraper 10 is designed as two fish fins spliced ​​together. The shape of the fish fins can help disperse the pressure of the water flow and provide a balancing force, so that the scraper 10 can maintain a stable rotation state. This minimizes the problem that the water resistance is too large when the auxiliary sealing component rotates, which affects the rotation state of the auxiliary sealing component and improves the stability of the auxiliary sealing operation.

[0043] Please see Figure 5 , Figure 6 and Figure 8 The sliding component shown in the figure includes a helical tooth 14 disposed at the bottom end of the sliding ring 13. The helical tooth 14 is evenly arranged in a circle around the axis of the sliding ring 13. The bottom end of the helical tooth 14 is meshed with a helical gear 15. One end of the helical gear 15 is fixedly connected to a first bevel gear set 16. The top end of the first bevel gear set 16 is equipped with a first transmission component.

[0044] In this embodiment: before the pressure cap 9 is embedded into the through hole for sealing, the obstructions on the outer wall of the pressure cap 9 need to be removed by the set rotation component. The cylinder 7 drives the top plate 8 and the pressure cap 9 to press down. The pressing down of the top plate 8 drives the first transmission component to transmit power. The first transmission component drives the first bevel gear set 16 to rotate. The rotation of the first bevel gear set 16 drives the helical gear 15 to rotate. The rotation of the helical gear 15 drives the helical tooth 14 to rotate, which drives the auxiliary sealing component to work and provides rotational force for the auxiliary sealing component to reduce obstructions on the outer wall of the pressure cap 9.

[0045] Please see Figure 5 , Figure 6 and Figure 11 The first transmission assembly shown in the figure includes a rotating rod 17 disposed at the top of the first bevel gear set 16. The rotating rod 17 is rotatably connected to the inside of the fixed frame 6, and both fixed frames 6 are provided with rotating rods 17. The two rotating rods 17 are configured to rotate in the same direction. A protrusion 18 is slidably embedded in the outer wall of the rotating rod 17. An annular groove is opened on the outer wall of the rotating rod 17 for the protrusion 18 to pass through. The protrusion 18 is fixedly connected to the top plate 8. One of the rotating rods 17 is fixedly connected to the first bevel gear set 16, and the bottom end of the other rotating rod 17 is equipped with a second transmission assembly.

[0046] In this embodiment: through the first transmission component, during the process of the cylinder 7 driving the top plate 8 and the pressure cover 9 to press down, the rotating rod 17 is rotatably connected inside the fixed frame 6. The pressing down of the top plate 8 drives the protrusion 18 to press down together. The pressing down of the protrusion 18 will abut against the annular groove of the rotating rod 17, giving the rotating rod 17 a downward force. The rotating rod 17 rotates under the force, converting the downward force into a force that drives the rotating component and the second transmission component to work, providing power to the rotating component and the second transmission component.

[0047] Please see Figure 4 and Figure 7 The guide assembly shown in the figure includes a guide block 19 disposed on one side of the sliding ring 13. The guide block 19 is fixedly connected to the sliding ring 13. The sliding ring 13 is slidably embedded in the interior of the precast base plate 1. The interior of the precast base plate 1 is provided with a guide groove 20 for the guide block 19 to slide. The guide groove 20 is set to be annular, inclined downward for a section and then turned horizontal. The guide groove 20 is symmetrically opened in opposite directions with the axis of the sliding ring 13 as the center.

[0048] In this embodiment: through the set guide component, when the rotating component drives the auxiliary sealing component to work, in order to make the auxiliary sealing component fit more closely to the outer wall of the pressure cap 9, the rotating component rotates and drives the auxiliary sealing component to rotate. One side of the connecting plate 11 inside the auxiliary sealing component is connected to the guide block 19. Under the guidance of the guide groove 20, the guide block 19 drives the connecting plate 11 to rotate along the guide groove 20 and press down with the cooperation of the first elastic element 12, and then rotates stably along the groove of the guide groove 20 to fit with the outer wall of the pressure cap 9. This avoids the problem of the cylinder 7 driving the top plate 8 and the pressure cap 9 to press down and getting stuck with the auxiliary sealing component, which would affect the normal operation of the components and ensure the stable operation of each component.

[0049] Please see Figure 5 and Figure 6 The fixing assembly shown in the figure includes a fixing plate 21 installed on the inner wall of the through hole. The fixing plate 21 is slidably embedded in the inside of the through hole. The bottom outer wall of the pressure cover 9 is provided with a fixing groove for fixing the fixing plate 21. Two fixing plates 21 are symmetrically installed. One fixing plate 21 is fixedly connected to a first connecting rod 22 on one side. The top end of the first connecting rod 22 is fixedly connected to a first rack plate 24. The top end of the first rack plate 24 is equipped with a second transmission assembly. The top end of the first rack plate 24 is meshed with a second gear 27. The other fixing plate 21 is fixedly connected to a second connecting rod 23 on one side. The bottom end of the second connecting rod 23 is fixedly connected to a second rack plate 26. The bottom end of the second rack plate 26 meshes with the second gear 27.

[0050] In this embodiment: After the pressure cap 9 and the through hole are completely sealed by the fixing component, the second elastic element 28 cooperates with the control component to release the elastic energy stored in the second elastic element 28 during the operation of the second transmission component, thereby driving the fixing component to fix the pressure cap 9. This minimizes the problem of the pressure cap 9 being pushed upward by the buoyancy of the water after the cylinder 7 is removed, which affects the sealing between the pressure cap 9 and the precast base plate 1, and improves the stability of the fixation between the pressure cap 9 and the precast base plate 1.

[0051] Please see Figure 5 , Figure 6 , Figure 9 and Figure 10The second transmission assembly shown in the figure includes a first gear 25 mounted on the top of the first rack plate 24. The first gear 25 is meshed with the first rack plate 24. A fixed rod is fixedly connected to one end of the first gear 25. A second elastic member 28 is sleeved on the outside of the fixed rod. The second elastic member 28 is fixedly connected to the first gear 25. A control assembly is mounted on the end of the second elastic member 28 away from the first gear 25 through the fixed rod. A second bevel gear set 30 is fixedly connected to the end of the first gear 25 away from the second elastic member 28. A movable rod 31 is fixedly connected inside the end of the second bevel gear set 30 away from the first gear 25. A locking block 32 is fixedly connected to the outer wall of the movable rod 31. A limiting block 33 is sleeved on the outside of the movable rod 31. A guide groove 20 for the locking block 32 to slide out is opened inside the bottom end of the limiting block 33. The limiting block 33 is fixedly connected to the bottom end of the rotating rod 17.

[0052] In this embodiment: through the second transmission component, when the first transmission component transmits the downward force, the first transmission component drives the limiting block 33 to rotate, the limiting block 33 drives the locking block 32 and the movable rod 31 to rotate, the movable rod 31 drives the second bevel gear set 30 to rotate, the second bevel gear set 30 drives the first gear 25 to rotate, and the first gear 25 drives the second elastic element 28 to rotate, providing the second elastic element 28 with elastic energy that can be stored.

[0053] Please see Figure 5 , Figure 6 and Figure 9 In the diagram, the second elastic element 28 is set as a torsion spring.

[0054] In this embodiment: through the provided second elastic element 28, during the pressing process of the cover 9, the cylinder 7 drives the top plate 8 and the cover 9 to press down. The pressing down of the top plate 8 drives the second transmission component to transmit power. The second transmission component drives the second elastic element 28 to rotate, generating a torsional force on the second elastic element 28. When the second elastic element 28 twists, the second elastic element 28 will be subjected to the torsional force, and the torsional force will cause the second elastic element 28 to deform. During the torsion process, elastic energy is stored, and when needed, this energy is released to provide torsional force, providing power for fixing the fixing component.

[0055] Please see Figure 5 , Figure 6 , Figure 9 and Figure 10 The control component shown in the figure includes a movable block 29 disposed at the end of the second elastic member 28 away from the first gear 25. The movable block 29 is slidably embedded inside the precast base plate 1. A third elastic member 35 is fixedly connected inside the precast base plate 1. A top pressure plate 34 is fixedly connected to the top of the third elastic member 35. A movable rod 31 is attached to the top of the top pressure plate 34.

[0056] In this embodiment: through the set control component, after the pressure cap 9 is fully inserted into the through hole, the fixing component is controlled to fix the pressure cap 9. The cylinder 7 drives the top plate 8 and the pressure cap 9 to press down. The top plate 8 presses down the moving block 29. The moving block 29 drives the first gear 25, the second elastic element 28, the second bevel gear set 30, the movable rod 31, the locking block 32 and the limiting block 33 to press down together, so that the movable rod 31 and the locking block 32 disengage from the guide groove 20 of the limiting block 33. Then, with the cooperation of the second transmission component and the second elastic element 28, the fixing component is fixed to the pressure cap 9, so that the pressure cap 9 is fully embedded in the through hole as much as possible. After it stops, it is fixed to avoid affecting the fixation of the pressure cap 9 during the movement and to ensure the firmness of the fixing component.
