[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 leveling device provided in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the leveling component provided in the embodiments of this application; Figure 3This is a schematic diagram of the structure of the compaction component provided in the embodiments of this application; Figure 4 for Figure 3 Enlarged view of part A in the image. 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 relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0016] Please refer to the attached document. Figure 1-4 This application provides a leveling device for a submarine cable rock-throwing vessel. The rock-throwing vessel is equipped with a rock-throwing pipe and a leveling device. The rock-throwing pipe and the leveling device are spaced apart along the length of the rock-throwing vessel. The rock-throwing pipe can output stones to form a rock pile on the submarine cable, and the leveling device can level the rock pile on the submarine cable.

[0017] The leveling device includes a movable frame and a leveling assembly. The leveling assembly is mounted on the movable frame. The stone-throwing vessel is connected to the movable frame via a steel wire rope and moves by raising and lowering the leveling device and traction the leveling device via the steel wire rope. The movable frame includes a mounting frame 110 and at least two skids 120. The two skids 120 are spaced apart at the bottom of the mounting frame 110 along a first direction.

[0018] The leveling assembly is mounted on the mounting frame 110 of the movable frame. The leveling assembly includes a scraper and a compactor 220, which are spaced apart along a second direction. The compactor 220 and the mounting frame 110 are equipped with a locking structure, allowing the compactor 220 to switch between locked and unlocked states. In the unlocked state, the compactor 220 can move along the height direction of the mounting frame 110, automatically falling onto the rock pile and adapting to the undulations of the rock pile to achieve compaction. In the locked state, the compactor 220 is fixed relative to the mounting frame 110, locked and unable to move relative to it.

[0019] During non-operational periods, the leveling device is pulled into the rock-dropping vessel by a steel wire rope through the moon pool. During operation, the leveling device is lowered to the seabed and moves with the rock-dropping vessel. Before the leveling device moves on the seabed and during non-operational periods, the compaction component 220 is locked. This prevents the compaction component 220 from moving relative to the mounting frame 110 due to the swaying of the rock-dropping vessel, thus protecting the compaction component 220 and extending the service life of the leveling device.

[0020] The first direction and the second direction are perpendicular to the height direction of the mounting bracket 110. Specifically, the first direction can be the length direction of the mounting bracket 110, and the second direction can be the width direction of the mounting bracket 110.

[0021] The leveling component can be, but is not limited to, a scraper 210, and the scraper 210 and the mounting bracket 110 are detachably fixedly connected. Optionally, the bottom of the mounting bracket 110 is provided with a mounting plate 111, the mounting plate 111 has a slot in which the scraper 210 is inserted, and the mounting plate 111 and the scraper 210 are fixedly connected by a bolt assembly.

[0022] The mounting bracket 110 is vertically mounted on the skid plate 120 to adjust the height of the leveling and compacting components 220, thereby improving the practicality of the equipment. Optionally, the skid plate 120 is equipped with a height adjustment column, and the mounting bracket 110 is slidably sleeved on the height adjustment column. The skid plate 120 is equipped with a hydraulic actuator, and the drive rod of the hydraulic actuator is connected to the mounting bracket 110 to drive the mounting bracket 110 to rise and fall.

[0023] The mounting frame 110 is equipped with a rope connecting ring, and the steel wire rope is connected to the rope connecting ring.

[0024] In some embodiments of this application, the compactor 220 is slidably disposed on the mounting bracket 110 along the height direction of the mounting bracket 110. The locking structure includes a locking component, which includes a locking rod 231 and a locking engagement hole 232. The locking engagement hole 232 is located on the compactor 220 and extends along a first direction. The locking rod 231 is movably disposed on the mounting bracket 110 along the first direction to extend into or retract from the locking engagement hole 232. When the compactor 220 is in the locked state, the locking rod 231 extends into the locking engagement hole 232 to restrict the movement of the compactor 220. When the compactor 220 is in the unlocked state, the locking rod 231 retracts from the locking engagement hole 232 to release the restriction of the compactor 220 by the locking rod 231. The above-described locking structure is not only simple in structure but also highly reliable.

[0025] In some embodiments of this application, the mounting bracket 110 is provided with a first mounting sleeve 112, the axial direction of the first mounting sleeve 112 is parallel to a first direction, the locking rod 231 is movably inserted into the first mounting sleeve 112 and the locking rod 231 and the first mounting sleeve 112 are slidably engaged, the outer periphery of the locking rod 231 is provided with a first stop ring 233, the first mounting sleeve 112 is provided with a second stop ring 114 and the second stop ring 114 is movably sleeved on the outer periphery of the locking rod 231, the second stop ring 114 is located on the side of the first stop ring 233 near the locking engagement hole 232, the locking assembly also includes a first elastic member 234, the first elastic member 234 is sleeved on the outer periphery of the locking rod 231 and compressed between the first stop ring 233 and the second stop ring 114. The locking structure also includes a drive mechanism, which is drivenly connected to the locking rod 231. When the compactor 220 switches from the unlocked state to the locked state, the drive mechanism drives the locking rod 231 to move along the direction close to the locking mating hole 232 and insert it into the locking mating hole 232. When the compactor 220 switches from the locked state to the unlocked state, the locking rod 231 moves along the direction away from the locking mating hole 232 under the drive of the first elastic member 234 and exits the locking mating hole 232.

[0026] The first elastic element 234 may be, but is not limited to, a first spring.

[0027] Optionally, two locking components are used. In this case, the mounting bracket 110 has two first mounting sleeves 112, which are spaced apart along a first direction. Two locking rods 231 are respectively inserted into the two first mounting sleeves 112. The two locking mating holes 232 and the two locking rods 231 are also spaced apart along the first direction. The two locking rods 231 are both located between the two locking mating holes 232. The driving mechanism drives the two locking rods 231 to simultaneously insert into or simultaneously withdraw from the corresponding locking mating holes 232. The driving mechanism includes a driving motor and a driving cam 242. The driving motor is located on the top of the mounting bracket 110. The output shaft 241 of the driving motor passes through the mounting bracket 110, and the driving cam 242 is located at the through end of the output shaft 241 of the driving motor. The two locking rods 231 are in contact with the cam surface of the driving cam 242. The drive cam 242 has two drive surfaces located on both sides of the drive cam 242. The two drive surfaces respectively contact and engage with the ends of the two locking rods 231, and the two drive surfaces are arranged rotationally symmetrically. Preferably, the top of the mounting bracket 110 is also provided with a reducer, and the drive motor and the reducer are connected in transmission. The drive cam 242 is mounted on the output shaft of the reducer.

[0028] The compactor 220 is locked to the mounting bracket 110 by two locking components, which improves the stability of the compactor 220 in the locked state, and the two locking components are driven by a drive mechanism, which simplifies the structure of the leveling device.

[0029] In some embodiments of this application, the compaction component 220 includes a pressure roller 224 and a support. The pressure roller 224 is rotatably mounted on the support. The support includes a support rod 221. The mounting frame 110 is provided with a second mounting sleeve 113. The axial direction of the second mounting sleeve 113 is parallel to the height direction of the mounting frame 110. The support rod 221 is inserted into the second mounting sleeve 113 and the support rod 221 and the second mounting sleeve 113 are slidably engaged. The locking engagement hole 232 is located on the support rod 221. The second mounting sleeve 113 is provided with a clearance through hole 116 for the support rod 221 to pass through, so that the locking rod 231 can be inserted into the locking engagement hole 232.

[0030] Optionally, when there are two locking components, there are two support rods 221 and two second mounting sleeves 113. The two second mounting sleeves 113 are spaced apart along the first direction, and the two support rods 221 are respectively inserted into the two second mounting sleeves 113. Both second mounting sleeves 113 are provided with clearance through holes 116. The bracket also includes a roller shaft 223, which is installed between the two support rods 221. The pressure roller 224 is movably sleeved on the outer periphery of the roller shaft 223, and at least one connecting rod 222 is provided between the two support rods 221.

[0031] In some embodiments of this application, a third stop ring 225 is provided on the outer periphery of the support rod 221. The third stop ring 225 is located inside the second mounting sleeve 113. A fourth stop ring 115 is provided inside the second mounting sleeve 113 and is movably sleeved on the outer periphery of the support rod 221. The third stop ring 225 is located on the side of the fourth stop ring 115 away from the pressure roller 224. The third stop ring 225 and the fourth stop ring 115 can stop each other to prevent the support rod 221 from exiting the second mounting sleeve 113.

[0032] Optionally, a second elastic element 226 is provided between the third stop ring 225 and the fourth stop ring 115. The second elastic element 226 is sleeved on the outer periphery of the support rod 221. The second elastic element 226 can elastically buffer the lifting and lowering of the compaction element 220, so that the pressure roller 224 can elastically load the rock pile and avoid over-compaction.
