Description

Technical Field

[0001] The utility model relates to the technical field of underwater robot recovery, in particular to an underwater docking recovery device based on ROV. Background Art

[0002] With the in-depth development of marine engineering, underwater docking and recovery technology has become a key technology in the fields of marine scientific research, seabed resource exploration, underwater equipment maintenance, etc. Traditional underwater docking and recovery devices often have problems such as long docking time, complex structure, and difficult operation, which seriously restrict the efficiency and safety of underwater operations. Therefore, it is of great significance to develop an underwater docking and recovery device based on ROV with simple structure, fast docking and easy operation.

[0003] Most of the existing underwater docking and recovery devices use complex mechanical structures and precise control systems to achieve docking with ROVs.

[0004] For example, the patent specification of an existing Chinese patent (publication number: CN115610629A) discloses an ROV-based docking and recovery device, including: a main frame; a lateral locking device, which is arranged in a first guide channel and can realize the positioning and locking of various types of underwater robots; a buffering and deceleration device, which can buffer and decelerate the underwater robot entering the first guide channel.

[0005] However, in the implementation of relevant technologies, it was found that the above-designed ROV-based docking and recovery device had the following problems: although the device can be applied to a variety of items, its structure is too complicated during use, docking is not convenient, maintenance is difficult, and practicality is not high.

[0006] In view of this, an underwater docking and recovery device based on ROV is provided to overcome the above-mentioned defects. Utility Model Content

[0007] The utility model aims to solve the shortcomings in the prior art and proposes an underwater docking recovery device based on ROV.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an underwater docking and recovery device based on ROV, including a docking sleeve and an abutment rod, a docking assembly for quick docking, the docking assembly including: an upper docking ear connected to the top end of the outer wall of the docking sleeve, a docking groove is provided inside the docking sleeve, a detachable abutment rod is provided in the docking groove, an abutment head is integrally formed at the top end of the abutment rod, and a rotatable clamping block is provided on the outer wall of the docking sleeve.

[0009] As a further description of the above technical solution: a first through hole is opened in the middle of the top surface of the docking sleeve, and the first through hole is communicated with the docking groove.

[0010] As a further description of the above technical solution: a through groove is opened on the outer wall of the docking sleeve, and mounting blocks are fixedly installed on the outer wall of the docking sleeve at positions on both sides of the through groove, a rotating rod is installed on the inner wall of the mounting block, and the clamping block is sleeved on the outer wall of the rotating rod. By arranging the clamping block to be sleeved on the outer wall of the docking sleeve and arranging the mounting blocks on both sides of the through groove, the clamping block can only rotate inside the through groove during subsequent use.

[0011] As a further description of the above technical solution: fasteners are provided on the side walls of the mounting block, and the rotating rod is installed on the inner wall of the mounting block through the fasteners. By providing the fasteners, the staff can disassemble the docking sleeve through the fasteners, making the inspection and maintenance process of the device simpler.

[0012] As a further description of the above technical solution: an arc groove is provided at one end of the clamping block, and the arc groove is in contact with the outer wall of the abutment rod in a closed state. A limiting block is fixedly installed on the bottom end of the clamping block. By setting the arc groove, the clamping block can limit the abutment head more stably, so that the abutment head will not easily escape from the limit of the clamping block without human power.

[0013] As a further description of the above technical solution: a cavity is opened inside the abutment rod, and a second through hole is opened in the middle position of the top surface of the abutment rod, and the second through hole is connected with the cavity. By setting the cavity and the second through hole and connecting the two to each other, the resistance of the abutment rod as a whole is reduced during the underwater movement. At the same time, the water flows through the cavity and the second through hole, which can keep the forward movement of the abutment rod stable and make it easier to dock with the docking sleeve.

[0014] As a further description of the above technical solution: the abutment head is arranged in a truncated cone shape, the bottom area of ​​the abutment head is larger than the bottom area of ​​the abutment rod, and the bottom end of the abutment rod is fixedly connected with a lower docking ear. By setting the specific shape of the abutment head to be truncated cone and the bottom area of ​​the abutment head to be larger than the bottom area of ​​the abutment rod, the two abutment heads can be smoothly connected to the top of the clamping block after the abutment rod is pushed into the docking groove, and the lower docking ear can be provided to facilitate the connection of the abutment rod with other instruments.

[0015] As a further description of the above technical solution: the through groove is adapted to the card block, the number of the card blocks is two, and the two card blocks are symmetrically installed on the outer wall of the docking sleeve. By setting the number of the card blocks to two and symmetrically installing them on the outer wall of the docking sleeve, the limiting effect of the card block on the second through hole is made more stable.

[0026] Embodiment 1

[0027] Reference Figure 1-4 The utility model provides an underwater docking and recovery device based on ROV, including a docking sleeve 1 and an abutment rod 2, a docking assembly for quick docking, and the docking assembly includes: an upper docking ear 101 connected to the top end of the outer wall of the docking sleeve 1, a docking groove is provided inside the docking sleeve 1, a detachable abutment rod 2 is provided in the docking groove, an abutment head 204 is integrally formed at the top end of the abutment rod 2, a rotatable clamping block 3 is provided on the outer wall of the docking sleeve 1, a first through hole 106 is provided in the middle position of the top surface of the docking sleeve 1, and the first through hole 106 is communicated with the docking groove.

[0028] During the specific implementation, the docking sleeve 1 is first docked and installed with the machine that needs to perform underwater operations through the upper docking ear 101. If the device is too large or too heavy, the user can also install a reinforcement through the installation ear 102 to prevent the connection between the docking sleeve 1 and the device from being disconnected. After fixing the docking sleeve 1 and the underwater operation device, the abutment rod 2 is connected to the ROV through the lower docking ear 201.

[0029] Then, the underwater working equipment is made to work normally. When it is needed to be recovered later, the abutment rod 2 is controlled to move by the ROV. During the process, the second through hole 203 is aligned with the bottom of the docking sleeve 1, and the abutment rod 2 is controlled to enter the docking groove opened inside the docking sleeve 1. During the advancement of the abutment rod 2, the second through hole 203 will first abut the two blocks 3, causing the blocks 3 to tilt outward. During the process of the blocks 3 tilting outward, the existence of the limit block 301 will abut against the outer wall of the docking sleeve 1 when the blocks 3 are over-tilted, so that the blocks 3 will not rotate excessively, and at the second through hole 2 03 moves to the top of the docking groove, the abutment rod 2 can be pulled backward. During the retreat process, the bottom end of the second through hole 203 of the abutment rod 2 contacts with the top of the block 3, which will press the block 3 downward. The block 3 will return to its initial state due to the pressure of the second through hole 203. At this time, the outer wall of the abutment rod 2 fits tightly with the arc groove 302, and the bottom of the second through hole 203 fits tightly with the top surface of the block 3. Therefore, after pulling the abutment rod 2, the abutment rod 2 will drive the docking sleeve 1, and the docking sleeve 1 will drive the underwater working equipment to move, thereby completing the recovery of the equipment.

[0030] By setting up a docking component, the device can quickly complete the docking with underwater working equipment, which can significantly shorten the docking time and thus improve the overall efficiency of underwater operations. In addition, the structure of the device is simple, and the simple structure means that the operation is easier, and the subsequent inspection and maintenance of the device is also simpler.

[0031] A through groove 103 is provided on the outer wall of the docking sleeve 1, and mounting blocks 104 are fixedly installed on the outer wall of the docking sleeve 1 at positions on both sides of the through groove 103. A rotating rod 107 is installed on the inner wall of the mounting block 104, and the clamping block 3 is sleeved on the outer wall of the rotating rod 107. By arranging the clamping block 3 to be sleeved on the outer wall of the rotating rod 107 and arranging the mounting blocks 104 on both sides of the through groove 103, the clamping block 3 can only rotate inside the through groove 103 during subsequent use.

[0032] A fastener 105 is provided on the side wall of the mounting block 104, and the rotating rod 107 is installed on the inner wall of the mounting block 104 through the fastener 105. By providing the fastener 105, the staff can disassemble the rotating rod 107 through the fastener 105, so that the process of inspection and maintenance of the device becomes simpler.

[0033] An arc groove 302 is provided at one end of the block 3, and the arc groove 302 is in contact with the outer wall of the abutment rod 2 in a closed state. A limit block 301 is fixedly installed at the bottom end of the block 3. By providing the arc groove 302, the block 3 can limit the abutment joint 204 more stably, so that the abutment joint 204 will not easily escape from the limit of the block 3 without human power.

[0034] A cavity 202 is provided inside the abutment rod 2, and a second through hole 203 is provided in the middle of the top surface of the abutment rod 2. The second through hole 203 is connected to the cavity 202. By providing the cavity 202 and the second through hole 203 and connecting the two, the resistance of the abutment rod 2 as a whole during its underwater movement is reduced. At the same time, the water flowing through the cavity 202 and the second through hole 203 can keep the forward movement of the abutment rod 2 stable, making it easier to dock with the docking sleeve 1.

[0035] The abutment joint 204 is arranged in a truncated cone shape, and the bottom area of ​​the abutment joint 204 is larger than the bottom area of ​​the abutment rod 2. The bottom end of the abutment rod 2 is fixedly connected with a lower docking ear 201. By setting the specific shape of the abutment joint 204 to be truncated cone and the bottom area of ​​the abutment joint 204 to be larger than the bottom area of ​​the abutment rod 2, the two abutment joints 204 can be smoothly connected to the top of the clamping block 3 after the abutment rod 2 is pushed into the docking groove, and the lower docking ear 201 is provided to facilitate the connection of the abutment rod 2 with other instruments.

[0036] The through groove 103 is adapted to the block 3, and there are two blocks 3. The two blocks 3 are symmetrically installed on the outer wall of the docking sleeve 1. By setting the number of the blocks 3 to be two and symmetrically installed on the outer wall of the docking sleeve 1, the limiting effect of the block 3 on the second through hole 203 is more stable.

[0037] Working principle:

[0038] When using the utility model, the docking sleeve 1 is first docked and installed with the machine that needs to perform underwater operations through the upper docking ear 101. If the device is too large or too heavy, the user can also install a reinforcement piece through the installation ear 102 to prevent the connection between the docking sleeve 1 and the device from being disconnected. After fixing the docking sleeve 1 and the underwater operation device, the abutment rod 2 is connected to the ROV through the lower docking ear 201.

[0039] Then, the underwater working equipment is made to work normally. When it is needed to be recovered later, the abutment rod 2 is controlled to move by the ROV. During the process, the second through hole 203 is aligned with the bottom of the docking sleeve 1, and the abutment rod 2 is controlled to enter the docking groove opened inside the docking sleeve 1. During the advancement of the abutment rod 2, the second through hole 203 will first abut the two blocks 3, causing the blocks 3 to tilt outward. During the process of the blocks 3 tilting outward, the existence of the limit block 301 will abut against the outer wall of the docking sleeve 1 when the blocks 3 are over-tilted, so that the blocks 3 will not rotate excessively, and at the second through hole 2 03 moves to the top of the docking groove, the abutment rod 2 can be pulled backward. During the retreat process, the bottom end of the second through hole 203 of the abutment rod 2 contacts with the top of the block 3, which will press the block 3 downward. The block 3 will return to its initial state due to the pressure of the second through hole 203. At this time, the outer wall of the abutment rod 2 fits tightly with the arc groove 302, and the bottom of the second through hole 203 fits tightly with the top surface of the block 3. Therefore, after pulling the abutment rod 2, the abutment rod 2 will drive the docking sleeve 1, and the docking sleeve 1 will drive the underwater working equipment to move, thereby completing the recovery of the equipment.

[0040] By setting up a docking component, the device can quickly complete the docking with underwater working equipment, which can significantly shorten the docking time and thus improve the overall efficiency of underwater operations. In addition, the structure of the device is simple, and the simple structure means that the operation is easier, and the subsequent inspection and maintenance of the device is also simpler.
