Description

Technical Field

[0001] The invention relates to the technical field of water excavation platforms, and in particular to a chain device for a combined water excavation platform. Background Art

[0002] The water excavation platform is a special equipment or work platform designed for excavation operations and related engineering construction operations in water environments (such as rivers, lakes, oceans, etc.). It floats on the water surface by the buoyancy of the floating structure and is fixed in the working position by the positioning and stabilization system. The operator controls the excavation equipment on the platform and uses the excavation arm and bucket to excavate the materials on the bottom of the water. It is mostly used in water conservancy project construction, port and waterway engineering, marine resource development, river dredging, etc.

[0003] The modular water excavation platform is an water excavation operation platform composed of multiple detachable and reassembled modules or components, which can be flexibly combined and disassembled according to different operation requirements, water conditions and transportation requirements.

[0004] Combined water excavation platforms are mostly composed of a main module and a sub-module. When in use, the main module and the sub-module need to be installed together to form a whole, and float on the water surface through the buoyancy of each module. The existing combined water excavation platforms have different functions and installation devices of the main module and the sub-module, which will cause differences in weight and area between the main module and the sub-module, resulting in different buoyancy between the main module and the sub-module, and then different drafts of the main module and the sub-module. Even after calculation and balance, it can only reduce the error, and it is difficult to make the drafts of the two exactly the same. This will make it difficult to align and lock the lock pin and lock mouth of the locking mechanism, which is not convenient for positioning, resulting in difficulty in installing the main module and the sub-module.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1-13A combined interlocking device for an above-water excavation platform comprises a main module 1 and a sub-module 2, wherein a connecting cavity 4 is provided on both sides of the main module 1; a main balancing mechanism comprises a second fixing plate 31 fixedly arranged on the top of both sides of the main module 1, and second push plates 32 are slidably arranged on both sides of the main module 1, and second push rods 33 are fixedly arranged at both ends of each second push plate 32, and each second push rod 33 is slidably connected to the main module 1; a sub-balancing mechanism comprises two first fixing plates 11 symmetrically fixed on the sub-module 2, and two first push rods 15 are slidably arranged on one side of the sub-module 2 close to the first fixing plate 11, and a first push plate 14 is fixedly arranged on one end of each first push rod 15 away from the sub-module 2; a second water storage tank 41 is fixedly arranged at both ends of the bottom of the main module 1, and a second water storage tank 41 is fixedly arranged at both ends of the sub-module Two first water tanks 17 are fixedly arranged at the bottom of the block 2. When the main module 1 and the auxiliary module 2 are close to each other, the first water tank 17 and the second water tank 41 are adaptively opened or closed through the main balancing mechanism and the auxiliary balancing mechanism to balance the draft between the main module 1 and the auxiliary module 2, and the positions of the main module 1 and the auxiliary module 2 are automatically aligned and locked; the auxiliary module 2 has two connecting cavities 4 symmetrically arranged on both sides of the main module 1, and the connecting cavities 4 on both sides of the main module 1 are used for inserting the corresponding first fixing plates 11 and the first pushing plates 14, the second fixing plates 31 are on the upper side of the corresponding connecting cavities 4, the top of the second fixing plates 31 is flush with the top of the main module 1, the second pushing plates 32 are flush with the side walls of the main module 1, and a part of the second pushing rod 33 is in the corresponding connecting cavity 4. The main module 1 and the auxiliary module 2 are both hollow inside. The main module 1 and the auxiliary module 2 are both prior art, and no further description is given here. The first fixing plate 11 and the first push plate 14 are flush with each other at the ends and both extend out of the side wall of the auxiliary module 2. The distance between the bottom surface of the first fixing plate 11 and the top surface of the first push plate 14 is slightly smaller than the distance between the top surface of the second push plate 32 and the bottom surface of the second fixing plate 31. When the draft of the main module 1 and the auxiliary module 2 are the same, that is, the top surfaces of the main module 1 and the auxiliary module 2 are flush, the first fixing plate 11 and the first push plate 14 can be inserted between the second fixing plate 31 and the second push plate 32. When the main module 1 and the auxiliary module 2 are installed together, the auxiliary module 2 is pulled toward Move towards the direction of the main module 1, and align the two ends of the sub-module 2 with the two ends of the main module 1 during the process of moving under the sub-module 2. When the draft of the main module 1 is greater than the draft of the sub-module 2, the top of the sub-module 2 is higher than the top of the main module 1. At this time, as the sub-module 2 moves towards the main module 1, the first push plate 14 abuts against the second fixed plate 31. As the sub-module 2 moves, the first push plate 14 pushes the first push rod 15 to move towards the direction of the sub-module 2, and the first fixed plate 11 is inserted between the second fixed plate 31 and the second push plate 32, so that the two first water storage tanks 17 at the bottom of the sub-module 2 are connected with the external water. At this time, the external water enters the first water storage tank 17, the weight of the sub-module 2 also increases, and the height of the sub-module 2 begins to decrease.When the top of the secondary module 2 is flush with the top of the main module 1, each first push plate 14 and the first push rod 15 rebound, and at this time the first push plate 14 is also inserted between the second fixing plate 31 and the second push plate 32, thereby cutting off the connection between each first water storage tank 17 and the outside world, so that the main module 1 and the secondary module 2 are aligned in the vertical direction, and the first fixing plate 11 and the first push plate 14 are inserted between the second fixing plate 31 and the second push plate 32, and the height between the main module 1 and the secondary module 2 is fixed by the abutment between the bottom surface of the first fixing plate 11 and the top surface of the second push plate 32 and the bottom surface of the second fixing plate 31 and the top surface of the first push plate 14. Similarly, when the draft of the main module 1 is less than the draft of the secondary module 2, the top of the secondary module 2 is lower than the top of the main module 1. At this time, as the secondary module 2 moves toward the main module 1 The second push plate 32 abuts against the first fixed plate 11. As the secondary module 2 moves, the second push plate 32 pushes the second push rod 33 to move in the direction close to the main module 1. The first push plate 14 is inserted between the second fixed plate 31 and the second push plate 32, so that the two second water storage tanks 41 at the bottom of the main module 1 are connected with the water from the outside. At this time, the water from the outside enters the second water storage tank 41, and the weight of the main module 1 also increases. The height of the main module 1 begins to drop. When the top of the secondary module 2 is flush with the top of the main module 1, each second push plate 32 and the second push rod 33 rebound. At this time, the first fixed plate 11 is also inserted between the second fixed plate 31 and the second push plate 32, thereby cutting off the connection between each second water storage tank 41 and the outside, so that the main module 1 and the secondary module 2 are aligned in the vertical direction.

[0035] Further, two second isolation disks 39 are rotatably provided on each second water storage tank 41, and a first isolation disk 22 is rotatably provided on each first water storage tank 17. A second connecting hole 391 is provided on the outer circumference of each second isolation disk 39, and a first connecting hole 23 is provided on the outer circumference of each first isolation disk 22. Two second drain holes 411 connected to the second connecting holes 391 are provided on the top of each second water storage tank 41, and a first drain hole 24 connected to the first connecting hole 23 is provided on the top of each first water storage tank 17; each first connecting hole The first connecting hole 23 and the second connecting hole 391 are both set to be L-shaped, one end of the first connecting hole 23 is opened on the outer peripheral surface of the first isolation disk 22, and the other end is opened at the bottom of the first isolation disk 22 and communicates with the first drain hole 24. Similarly, one end of the second connecting hole 391 is opened on the outer peripheral surface of the second isolation disk 39, and the other end is opened at the bottom of the second isolation disk 39 and communicates with the corresponding second drain hole 411. Each second connecting hole 391 is connected to each second drain hole 411 in a one-to-one correspondence, and the main module 1 and the auxiliary module 2 are connected. A blocking plate 5 for blocking the first isolation disk 22 and the second isolation disk 39 is fixedly provided, and each blocking plate 5 is provided with a liquid inlet 12 that can be connected to the first connecting hole 23 or the second connecting hole 391. The outer walls of the main module 1 and the sub-module 2 are provided with a through hole (not marked in the figure) connected to the liquid inlet 12. In the initial state, the first connecting hole 23 and the second connecting hole 391 are not connected to the liquid inlet 12. When the first push plate 14 moves toward the sub-module 2, it drives the first isolation disk 22 to rotate, so that the second connecting hole 391 on the first isolation disk 22 A connecting hole 23 is connected to the liquid inlet hole 12. At this time, water from the outside can enter the first connecting hole 23 through the liquid inlet hole 12, and enter the first water tank through the first connecting hole 23 and the first liquid discharge hole 24. Similarly, when the second push plate 32 and the second push rod 33 move toward the direction close to the main module 1, the second isolation plate 39 is driven by the second push rod 33 to rotate so that the second connecting hole 391 is connected to the corresponding liquid inlet hole 12, so that water enters the second water tank 41, and then the draft of the main module 1 and the sub-module 2 are adjusted to make the two flush.

[0036] Furthermore, a first rotating shaft 21 is fixedly provided on the top of each first isolation disk 22, a first rotating disk 25 is fixedly provided on each first rotating shaft 21, a second rotating shaft 38 is fixedly provided on the top of each second isolation disk 39, and a second rotating disk 36 is fixedly provided on the top of each second rotating shaft 38; a fixed block 112 is fixedly provided on each first fixed plate 11, and the first push plate 14 is limited by the fixed block 112, and a movable bin 18 is opened inside the main module 1 and the sub-module 2, and the blocking plate 5 is fixedly provided in the corresponding movable bin 18, and the internal space of the main module 1 and the sub-module 2 is separated from the outside world by the movable bin 18 to prevent water from entering the main module 1 or the sub-module 2 through the liquid inlet hole 12 and affecting the buoyancy of the platform, and the movable bin 18 on the main module 1 is provided for the second isolation disk 39 and the second The rotating shaft 38 and the second rotating disk 36 are movable, and the movable bin 18 on the sub-module 2 allows the first isolation disk 22, the first rotating shaft 21 and the first rotating disk 25 to move. When the first push rod 15 moves toward the direction close to the sub-module 2, the first push rod 15 pushes the first rotating disk 25 to rotate, and the first rotating disk 25 drives the first isolation disk 22 to rotate through the first rotating shaft 21. When the first push plate 14 abuts against the corresponding fixed block 112, the first connecting hole 23 on the first isolation disk 22 is just aligned with the corresponding liquid inlet hole 12, and water can enter the first liquid storage tank at this time. When the second push plate 32 moves toward the main module 1, it drives the corresponding second rotating disk 36 to rotate, and when the corresponding second isolation disk 39 is driven to rotate through the rotating shaft, the second connecting hole 391 is aligned and connected with the corresponding liquid inlet hole 12.

[0037] Specifically, a first spring 16 is fixedly arranged between each first push plate 14 and the side wall of the auxiliary module 2, and a second spring 34 is fixedly arranged between each second push plate 32 and the main module 1; each second spring 34 is sleeved on the outer circumferential surface of each second push rod 33 in a one-to-one correspondence. When the first push plate 14 moves in a direction close to the auxiliary module 2, the first spring 16 is compressed. When the auxiliary module 2 moves down so that its top is flush with the top of the main module 1, the first push plate 14 is separated from the second fixed plate 31. At this time, the first push plate 14 is returned to its initial position by the first spring 16. When the first push plate 14 moves in a direction away from the auxiliary module 2, it drives the first isolation disk 22 to rotate so that the first connecting hole 23 is again aligned with the corresponding liquid inlet The hole 12 is misaligned, so that the first connecting hole 23 is blocked. At this time, water no longer enters the first water tank 17. Similarly, when the second push plate 32 moves toward the direction close to the main module 1, the second spring 34 is compressed. When the main module 1 moves down and aligns with the sub-module 2, the second push plate 32 moves down and separates from the first fixed plate 11. At this time, the second spring 34 drives the second push plate 32 to reset, thereby driving the second isolation plate 39 to rotate so that the second connecting hole 391 is no longer connected to the liquid inlet hole 12. The outer peripheral surfaces of the first isolation plate 22 and the second isolation plate 39 both include sealing sleeves (not marked in the figure), which prevent water from entering the first water tank 17 or the second water tank 41 without connection.

[0038] A first driving rod 26 is fixedly provided on the top of each first rotating disk 25, a first driving frame 27 is fixedly provided on the end of each first push rod 15 away from the first push plate 14, a second driving rod 37 is fixedly provided on the top of each second rotating disk 36, and a second driving frame 35 is fixedly provided on the end of each second push rod 33 away from the second push plate 32; each first driving rod 26 is movably arranged in each first driving frame 27 in a one-to-one manner, and each second driving rod 37 is movably arranged in the second driving frame 35 in a one-to-one manner. The first driving rod 26 is fixedly provided on a side of the first rotating disk 25 close to the outer circumference, and the second driving rod 37 is fixedly provided on a side of the second rotating disk 36 close to the outer circumference. The first driving rod 26 can slide and rotate in the first driving frame 27, and the second driving rod 37 can slide and rotate in the second driving frame 35, and the top of each movable bin 18 is provided with an arc groove (not marked in the figure) that cooperates with the first driving rod 26 or the second driving rod 37. Each arc groove is a quarter circle, and the tops of the first driving rod 26 and the second driving rod 37 slide in the corresponding arc groove. When the first push rod 15 moves toward the direction close to the sub-module 2, the first driving frame 27 pushes the corresponding first driving rod 26 to move, thereby driving the first isolation disk 22 to rotate. When the second push rod 33 moves toward the direction close to the main module 1, the second driving frame 35 pushes the second driving rod 37 to perform a circular motion, thereby allowing the isolation disk to rotate, so that the first connecting hole 23 and the second connecting hole 391 are connected or staggered with the corresponding liquid inlet hole 12.

[0039] In another embodiment of the present invention: four ratchets 48 are rotatably arranged on the main module 1, and a limiting rod 49 is fixedly arranged on each ratchet 48. Alignment grooves 13 adapted to the limiting rod 49 are provided on both sides of the sub-module 2, and a limiting groove 131 is provided inside each alignment groove 13; the limiting groove 131 is adapted to the cross-section of the limiting rod 49, and the four ratchets 48 are evenly distributed at the four corners of the main module 1 and are in the corresponding active cavity. As the sub-module 2 approaches the main module 1, when the end faces of the first fixing plate 11 and the second fixing plate 31 are aligned, the ratchet 48 starts to rotate 180 degrees, thereby driving the corresponding limiting rod 49 to rotate 180 degrees, and the limiting rods 49 at both ends of the main module 1 rotate to abut against the two side walls of the sub-module 2 close to the main module 1, so that the side walls at both ends of the sub-module 2 are aligned with the side walls at both ends of the main module 1. In the initial state, the limit rod 49 is parallel to the end side wall of the main module 1. When the limit rod 49 rotates 180 degrees, it will enter the corresponding alignment groove 13 and abut against the inner wall of the alignment groove 13. When the limit rod 49 pushes the inner wall of the alignment groove 13, the secondary module 2 is clamped between the limit rods 49 at both ends of the main module 1, so that the main module 1 and the secondary module 2 are aligned in the horizontal direction. When the top surfaces of the main module 1 and the secondary module 2 are aligned, the first push plate 14 and the first fixed plate 11 are inserted between the second push plate 32 and the second fixed plate 31. At this time, the secondary module 2 can move toward the main module 1 again, and at this time the limit rod 49 is aligned with the corresponding limit groove 131. As the secondary module 2 moves again, the limit rod 49 is inserted into the corresponding limit groove 131, so that the secondary module 2 cannot move along the side wall of the main module 1.

[0040] Furthermore, each ratchet 48 is sleeved with a toothed ring 45 on its outer circumference, and each toothed ring 45 is fixedly provided with four pawls 451 adapted to the ratchet 48 inside. Four toothed plates 44 are slidably provided on the main module 1, and each toothed plate 44 meshes with each toothed ring 45 one by one; four support rods 46 for supporting the toothed ring 45 are fixedly provided on the main module 1. When the first fixed plate 11 or the first push plate 14 is inserted between the second fixed plate 31 and the second push plate 32, the corresponding toothed plate 44 will be pushed to move in the direction close to the toothed ring 45, thereby causing the corresponding toothed ring 45 to rotate. When the toothed ring 45 rotates, the corresponding ratchet 48 is driven to rotate through the pawls 451, thereby causing the limit rod 49 to rotate 180 degrees. When the toothed plate 44 moves to the outside of the main module 1, it will drive the toothed ring 45 to rotate. At this time, the pawls 451 can make the ratchet 48 rotate in the direction away from the main module 1. When the toothed plate 44 moves toward the inside of the main module 1, it drives the toothed ring 45 to reverse, and at this time the ratchet 48 will not rotate.

[0041] Specifically, four moving plates 42 are slidably arranged in the main module 1, each moving plate 42 is fixedly connected to each tooth plate 44 in a one-to-one correspondence, and each second push plate 32 is fixedly arranged with an abutment plate 43 on one side close to the moving plate 42; Fig.13As shown, one side of each movable plate 42 away from the main module 1 is set to an inclined surface, and each movable plate 42 is in the corresponding active cavity. An extension plate 421 is fixedly provided on each movable plate 42, and the inclined surface of the movable plate 42 is extended by the extension plate 421. When the first push plate 14 abuts against the second fixed plate 31, the first push plate 14 is inserted between the second push plate 32 and the second fixed plate 31. At this time, the first fixed plate 11 abuts against the inclined surface of the corresponding movable plate 42, thereby pushing the corresponding movable plate 42 to move in the direction close to the gear ring 45, thereby driving the corresponding tooth plate 44 to move, causing the corresponding gear ring 45 to rotate, and then driving the corresponding ratchet 48 and the limiting rod 49 to rotate through the pawl 451. When the first fixed plate 11 abuts against the second push plate 32, the second push plate 32 is pushed to move through the first fixed plate 11, and the first fixed plate 11 When the second push plate 32 moves, the abutment plate 43 abuts against the inclined surface of the moving plate 42, and the moving plate 42 drives the corresponding tooth plate 44 to move in the direction close to the gear ring 45, thereby driving the corresponding limit rod 49 to rotate, so that when the top surface of the sub-module 2 is higher or lower than the top surface of the main module 1, the moving plate 42 can be pushed to move, so that the limit rod 49 can be rotated to align the main module 1 and the sub-module 2 in the horizontal direction and insert it into the corresponding limit groove 131 to lock the main module 1 and the sub-module 2 in the horizontal direction, and the corresponding moving plate 42 can be pushed to move through the abutment plate 43. After the moving plate 42 drives the limit rod 49 to rotate 180 degrees, the abutment plate 43 abuts against the main module 1. At this time, the second push plate 32 will no longer move, and at the same time, the second connecting hole 391 on the second isolation disk 39 is aligned with the corresponding liquid inlet hole 12.

[0042] In another embodiment of the present invention, each first fixing plate 11 is provided with a clamping groove 111, and a torsion spring 47 is fixedly arranged between the bottom of each gear ring 45 and the main module 1; Fig.13 As shown, when a part of the first fixed plate 11 enters between the second fixed plate 31 and the second push plate 32, the movable plate 42 is pushed to move by the first fixed plate 11 or the abutment plate 43. When the first fixed plate 11 completely enters between the second fixed plate 31 and the second push plate 32, the corresponding tooth ring 45 is reversed by the torsion spring 47, and then the corresponding tooth plate 44 and the movable plate 42 are pushed in the direction close to the first fixed plate 11, and then the movable plate 42 is clamped into the clamping groove 111 on the first fixed plate 11, so that the main module 1 and the secondary module 2 are fixed together. At this time, the secondary module 2 is fixed to the main module 1 in the vertical direction by the first fixed plate 11, the second fixed plate 31, the first push plate 14, and the second push plate 32, and the secondary module 2 is fixed to the main module 1 in the horizontal direction by the movable plate 42, the clamping groove 111, the limit groove 131 and the limit rod 49, thereby fixing the secondary module 2 and the main module 1 together.

[0043] A traction shaft 51 is rotatably arranged in the main module 1, and two traction ropes 52 are fixedly arranged at both ends of the traction shaft 51, and a ring 54 is fixedly arranged at one end of each traction rope 52 away from the traction shaft 51, and fixed columns 55 are fixedly arranged on both side walls of the sub-module 2; the traction shaft 51 passes through the main module 1 and is exposed from both ends of the main module 1, a servo motor 3 is fixedly arranged on the main module 1, and the output end of the servo motor 3 is fixedly connected to the traction shaft 51, and three partitions 53 are fixedly arranged at both ends of the traction shaft 51, and the two ends of the traction shaft 51 are divided into two winding chambers by the three partitions 53, and circular plates (not marked in the figure) are fixedly arranged on the three partitions 53 on the same side, and holes for the traction ropes 52 to pass through are provided on the circular plates, and the traction ropes 52 are wound up in each winding chamber one by one, and the width of the winding chamber is adapted to the diameter of the traction rope 52, and the traction shaft 51 rotates one circle through the winding chamber The traction ropes 52 at both ends are wound up to the same length. Sub-modules 2 need to be installed on both sides of the main module 1. Each fixing column 55 is provided with an annular groove (not shown in the figure) adapted to the ring 54. When installing the sub-module 2, first put the main module 1 and the sub-module 2 into water, then pull out the two traction ropes 52 at both ends of the traction shaft 51, and put the corresponding rings 54 in the annular grooves of each fixing column 55, then start the servo motor 3, the servo motor 3 drives the traction shaft 51 to rotate, and each traction rope 52 is wound up synchronously, so that the sub-module 2 moves toward the main module 1. Since the traction ropes 52 at both ends of the sub-module 2 have the same length and the same winding speed, when the traction ropes 52 are wound up, the pulling force of the traction ropes 52 at both ends will gradually align the sub-module 2 with the main module 1 in the horizontal direction, and push the sub-module 2 to be completely aligned with the main module 1 when the limit rod 49 rotates.

[0044] Working principle: The servo motor 3 drives the traction shaft 51 to rotate, so that the traction rope 52 pulls the two ends of the sub-module 2 at the same time, so that the sub-module 2 moves toward the main module 1 and gradually aligns with the main module 1 in the horizontal direction. As the sub-module 2 moves, the end surface of the second fixed plate 31 on the main module 1 and the end surface of the first fixed plate 11 on the sub-module 2 are gradually flush in the vertical direction. At this time, if the draft of the main module 1 is large, the second fixed plate 31 will abut against the first push plate 14, and with the pulling force of the traction rope 52, the first push plate 14 drives the first push rod 15 to move in the direction close to the sub-module 2. The first push plate 14 drives the corresponding push rod 15 through the first drive frame 27 and the first drive rod 26. The first isolation disk 22 rotates to align the first connecting hole 23 with the corresponding liquid inlet hole 12, so that water can enter the first water storage tank 17. At this time, the first fixed plate 11 is inserted between the second fixed plate 31 and the second push plate 32, and pushes the corresponding movable plate 42 to move, so that the movable plate 42 and the tooth plate 44 drive the gear ring 45 to rotate. When the gear ring 45 rotates, it drives the ratchet 48 and the limit rod 49 to rotate 180 degrees. At this time, the servo motor 3 is stopped, and the limit rod 49 is abutted against the inner wall of the alignment groove 13 to align the sub-module 2 with the main module 1 in the horizontal direction. As the water in the first liquid storage tank increases, the gravity of the sub-module 2 increases and gradually moves downward. When the top surface of the sub-module 2 faces the top surface of the main module 1 When the two modules are aligned, the first push plate 14 is reset and inserted between the second push plate 32 and the second fixed plate 31. At this time, the first isolation disk 22 is reset to block the first connecting hole 23, and the servo motor 3 is started again. The sub-module 2 continues to move toward the main module 1, and the limiting rod 49 is inserted into the corresponding limiting groove 131. When the first fixed plate 11 completely enters between the second fixed plate 31 and the push plate, the moving plate 42 is clamped into the clamping groove 111 through the torsion spring 47, so that the sub-module 2 is fixed to the main module 1. Similarly, when the draft of the main module 1 is small, the movement of the sub-module 2 will cause the first fixed plate 11 to abut against the second push plate 32 and push the second push plate 32 to move in the direction close to the main module 1. When the second push plate 32 drives the limit rod 49 to rotate 180 degrees, the servo motor 3 stops. At this time, the limit rod 49 aligns the main module 1 with the sub-module 2, and the second push rod 33 pushes the second isolation disk 39 to rotate to align the second connecting hole 391 with the corresponding liquid inlet hole 12, so that water can enter the second liquid storage tank, and then the main module 1 moves downward. When the top surfaces of the main module 1 and the sub-module 2 are aligned, the second push plate 32 is reset, so that the second connecting hole 391 is staggered with the liquid inlet hole 12, and the servo motor 3 is started again. The first fixed plate 11 completely enters the active cavity, and the movable plate 42 moves into the clamping groove 111. At this time, the main module 1 and the sub-module 2 are fixedly connected together in all directions.
