AI Technical Summary
In existing interlocking drainage systems, when the foundation beneath the outermost row of concrete blocks is eroded and subsides, it causes deflection, increasing the exposed area and thus accelerating the failure of the system.
Design an interlocking device in which each row of fixed interlocking blocks is connected by a connecting rope, and is equipped with a movable interlocking block and a counterweight. The movable interlocking block is connected to the fixed interlocking block by a connecting rope. The counterweight is located at the end of the fixed interlocking block away from the movable interlocking block, so that when the outermost row of fixed interlocking blocks sinks, the next outermost row of fixed interlocking blocks is moved by the connecting rope to reduce the exposed area and provide ballast.
This effectively reduced the failure rate of the interlocking system under foundation erosion and extended the service life of the device.

Abstract
Description
Technical Field
[0001] This invention generally relates to the field of submarine cable laying technology, and specifically to an interlocking cable laying device. Background Technology
[0002] Interlocking slabs, also known as flexible slabs, are used to protect submarine cables. An interlocking slab typically consists of multiple concrete blocks arranged in a matrix and ropes connecting these blocks, with a certain distance between each row of blocks.
[0003] However, when the foundation supporting the outermost row of concrete blocks in the interlocking system is eroded and subsided, it will cause the outermost row of concrete blocks to deflect. This will increase the exposed area of the foundation between the outermost row of concrete blocks and the next outermost row of concrete blocks in the interlocking system, thus accelerating the failure rate of the interlocking system. Summary of the Invention
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an interlocking device.
[0005] This application provides an interlocking device, characterized in that it includes multiple fixed interlocking blocks arranged in multiple rows and columns. Multiple fixed interlocking blocks in each row are fixedly connected to a first connecting rope, and multiple fixed interlocking blocks in each column are fixedly connected to a second connecting rope. At least one row of movable interlocking blocks is provided between each outermost row of fixed interlocking blocks and its adjacent next outermost row of fixed interlocking blocks. In each row of movable interlocking blocks, multiple movable interlocking blocks are fixedly connected to a third connecting rope. Multiple movable interlocking blocks are movably sleeved on multiple second connecting ropes in a one-to-one correspondence with multiple fixed interlocking blocks in the outermost row of fixed interlocking blocks, and a fourth connecting rope connects each movable interlocking block to its corresponding fixed interlocking block in the outermost row of fixed interlocking blocks.
[0006] Furthermore, in each row of movable interlocking blocks, multiple movable interlocking blocks are set one-to-one with multiple fixed interlocking blocks in the secondary outer row of fixed interlocking blocks, and each movable interlocking block and the corresponding fixed interlocking block in the secondary outer row of fixed connecting locks are connected by a fifth connecting rope.
[0007] Furthermore, each of the outermost fixed interlocking blocks is equipped with a counterweight.
[0008] Furthermore, the counterweight of the counterweight unit is adjustable.
[0009] Furthermore, the counterweight is located at the end of the fixed interlocking block away from the movable interlocking block, so that the center of gravity of the fixed interlocking block is located in its middle on the side away from the movable interlocking block.
[0010] Furthermore, the fourth connecting rope is located above the second connecting rope.
[0011] Furthermore, there is an anti-rotation fit between the movable interlocking block and the second connecting rope.
[0012] Furthermore, the connecting rope is fitted with an anti-rotation cylinder, and the movable interlocking block is fitted with a sleeve hole and is fitted onto the outer periphery of the anti-rotation cylinder through the sleeve hole, with an anti-rotation fit between the anti-rotation cylinder and the hole wall surface.
[0013] The interlocking device provided in this application has at least one row of movable interlocking blocks between each outermost fixed interlocking block and the adjacent secondary outermost fixed interlocking block. Multiple movable interlocking blocks in each row are fixedly connected to a third connecting rope. Multiple movable interlocking blocks in each row are movably sleeved on multiple second connecting ropes in a one-to-one correspondence. Multiple movable interlocking blocks are also connected to multiple fixed interlocking blocks in the outermost fixed interlocking block in a one-to-one correspondence with a fourth connecting rope. When the outermost fixed interlocking block flips due to the subsidence of the foundation below, the outermost fixed interlocking block pulls the secondary outermost fixed interlocking block to move through the fourth connecting rope, thereby reducing the exposed foundation area between the outermost and secondary outermost fixed interlocking blocks and ballasting the subsidence edge of the foundation. This reduces the scouring speed of the foundation supported by the interlocking block and delays the failure rate of the interlocking block. Attached Figure Description
[0014] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 This is a schematic diagram of the interlocking device provided in an embodiment of this application. Detailed Implementation
[0015] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0016] Please refer to the attached document. Figure 1This application provides an interlocking device, including multiple fixed interlocking blocks 110 arranged in multiple rows and columns. Each row of fixed interlocking blocks 110 is fixedly connected to a first connecting rope, and each column of fixed interlocking blocks 110 is fixedly connected to a second connecting rope 120. At least one row of movable interlocking blocks is provided between each outermost row of fixed interlocking blocks and its adjacent next outermost row of fixed interlocking blocks. The number of movable interlocking blocks 130 in each row of movable interlocking blocks is the same as the number of fixed interlocking blocks 110 in each row of fixed interlocking blocks. In each row of movable interlocking blocks, multiple movable interlocking blocks 130 are fixedly connected to a third connecting rope. Each movable interlocking block 130 is movably sleeved on multiple second connecting ropes 120 in a one-to-one correspondence with each fixed interlocking block 110 in the outermost row of fixed interlocking blocks, and a fourth connecting rope 140 connects each movable interlocking block 130 to its corresponding fixed interlocking block 110 in the outermost row of fixed interlocking blocks.
[0017] The scour and settlement direction of the interlocking foundation is usually from the outside to the inside, meaning that the foundation below the outermost fixed interlocking block experiences scour and settlement first. When scour and settlement occurs in the foundation below the outermost fixed interlocking block, the outermost fixed interlocking block may flip downwards due to local loss of support. During the flipping process, the outermost fixed interlocking block pulls the second outermost fixed interlocking block outwards via the fourth connecting rope 140. This reduces the exposed foundation area between the outermost and second outermost fixed interlocking blocks, and the moved outermost fixed interlocking block 110 applies ballast to the edge of the foundation settlement, reducing the scour rate of the interlocking foundation and delaying the failure rate of the interlocking system.
[0018] The movable interlocking block 130 has a through hole in its center and is movably fitted around the outer periphery of the second connecting rope 120 through the hole. Optionally, the fourth connecting rope 140 is located above the second connecting rope 120, so that the outermost row of fixed interlocking blocks can pull the movable interlocking block 130 a larger distance.
[0019] The movable interlocking block 130 and the fixed interlocking block 110 can be, but are not limited to, concrete blocks.
[0020] In some embodiments of this application, in each row of movable interlocking blocks, multiple movable interlocking blocks 130 are configured one-to-one with multiple fixed interlocking blocks 110 in the next outermost row of fixed interlocking blocks 110, and a fifth connecting rope 150 connects each movable interlocking block 130 to its corresponding fixed interlocking block 110 in the next outermost row of fixed connecting locks. The aforementioned fifth connecting rope 150 can constrain the movement range of the movable interlocking block 130 connected to it, preventing the movable interlocking block 130 from flipping over to the foundation settlement area along with the outermost row of fixed interlocking blocks.
[0021] In some embodiments of this application, the movable interlocking block 130 and the second connecting rope 120 are anti-rotationally engaged to restrain the movable interlocking block 130 from flipping during the interlocking process, so that both the movable interlocking block 130 and the fixed interlocking block 110 can be placed flat on the foundation.
[0022] The connecting rope is fitted with an anti-rotation cylinder, and the movable interlocking block 130 is fitted with a sleeve hole and is fitted onto the outer periphery of the anti-rotation cylinder through the sleeve hole, with an anti-rotation fit between the anti-rotation cylinder and the wall surface of the sleeve hole. Optionally, the sleeve hole is polygonal in shape, such as a rectangle, and the anti-rotation cylinder and the sleeve hole are adapted in shape to achieve an anti-rotation fit.
[0023] In some embodiments of this application, the fixed interlocking blocks 110 in the outermost row of fixed interlocking blocks are provided with counterweights to increase the weight of the fixed interlocking blocks 110. These counterweights not only increase the weight of the outermost row of fixed interlocking blocks 110, suppressing foundation edge erosion and improving anti-lifting capability, but also ensure that the weight of the fixed interlocking blocks 110 in the outermost row of fixed interlocking blocks is greater than the weight of the movable interlocking block 130, thus improving the pulling effect on the movable interlocking block 130.
[0024] Optionally, the counterweight is located at the end of the fixed interlocking block 110 away from the movable interlocking block 130, so that the center of gravity of the fixed interlocking block 110 is located in the middle on the side away from the movable interlocking block 130, so as to further improve the ability to suppress the scouring of the foundation edge.
[0025] In some embodiments of this application, the counterweight of the counterweight unit is adjustable to adjust the weight of the outermost fixed interlocking block to meet the usage requirements of the interlocking unit on different types of foundations.
[0026] Optionally, each of the outermost fixed interlocking blocks 110 has a receiving cavity at its bottom. Each fixed interlocking block 110 has a threaded connecting rod extending into the receiving cavity. The counterweight is a counterweight block with a threaded connecting hole in its center, through which it is screwed to the threaded connecting rod. The density of the counterweight block should be greater than the density of the fixed interlocking block 110; for example, an iron counterweight block may be used.
[0027] It should be understood that before laying the interlocking system, appropriate counterweights need to be selected and installed into the receiving cavity according to the counterweight requirements.
[0028] It should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used above to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.
