Description

Technical Field

[0001] The present application relates to the technical field of underwater thrusters, and in particular to a hoisting underwater thruster suitable for seabed operations. Background Art

[0002] As a key marine engineering equipment, underwater thrusters play an indispensable role in various marine activities. Whether it is seabed exploration, marine surveys, installation and maintenance of underwater devices, or supporting autonomous navigation and control of underwater vehicles, underwater thrusters need to ensure efficient and stable operation in complex and changeable underwater environments.

[0003] For example, publication number CN113697070B discloses a fully rotating underwater thruster. The coordinated use of a first steering gear and a second steering gear enables the device to be adjusted 360 degrees without restriction. Compared with a traditional swinging thruster, the device is not restricted by cables and mechanical structures and will not have a steering blind spot. At the same time, the free rotation of the device makes the device more flexible. When the direction needs to be adjusted, the propeller can be adjusted in one step without the need for continuous and repeated operations, which makes the propeller rotation propulsion efficiency higher to a certain extent.

[0004] In the application and development of underwater thrusters, although certain technical progress has been made, there are still some problems in actual use: traditional underwater thrusters generally lack effective protection measures for propellers during use. When the equipment is in a complex marine environment, such as dense aquatic plants and a lot of garbage, the propeller is prone to inhale debris such as aquatic plants and garbage, causing the propeller to become stuck or even damaged. This situation will not only directly affect the normal working efficiency of the underwater thruster, but may also pose a serious threat to the long-term stable operation of the equipment.

[0005] In order to deal with the above problems, some research and development investments have been made in the existing technical solutions, and some devices or methods with preliminary protection functions have been proposed. However, most of these improvements focus on reducing the entry of debris into the propeller area through physical isolation, and fail to fundamentally solve the problem of propeller entanglement or blockage. At the same time, these improvement measures often require additional maintenance costs, and there are certain limitations and shortcomings in actual operation, and they still cannot fully guarantee the continuous and stable operation of underwater propulsion in complex environments.

[0006] Therefore, in view of the performance limitations of traditional underwater propulsion systems in complex environments and the limitations of existing technical improvement measures, it is necessary to fundamentally solve the problem of propellers getting stuck or damaged in complex sea areas, improve the working efficiency of underwater propulsion systems and the service life of equipment, so as to further promote the continuous progress and development of underwater propulsion technology.

[0013] Preferably, a bidirectional thread is provided on the rotating shaft, and the annular plate cooperates with the bidirectional thread and is installed on the rotating shaft by means of a threaded connection.

[0014] Preferably, the support frame is composed of a plurality of circumferentially evenly distributed fixed rods, a fixed circular plate and an annular circular plate are respectively installed at both ends of the fixed rods, and the rotating shaft is installed on the fixed circular plate through a bearing, the annular circular plate is installed on the inner wall of the circular shell, and a plurality of circumferentially evenly distributed blocking rods are arranged adjacent to the fixed rods and between the fixed circular plate and the annular circular plate to prevent external impurities from entering the interior of the circular shell.

[0015] Preferably, a clamping groove for placing a blocking rod is provided on a fixed circular plate close to the differential and between adjacent fixed rods, and a clamping block 1 for limiting the blocking rod is provided on the clamping groove. A clamping groove for placing the blocking rod is also provided on the annular circular plate corresponding to the fixed circular plate, and a clamping block 2 for limiting the blocking rod is provided on the corresponding clamping groove.

DETAILED DESCRIPTION

[0034] The following is combined with Figures 1 to 9 This application is described in further detail.

[0035] The embodiment of the present application discloses a sling-mounted underwater propeller suitable for seabed operations, which reduces the possibility of impurities entering the interior of the sling-mounted underwater propeller by actively removing aquatic plants and passively blocking aquatic plants.

[0036] Embodiment 1:

[0037] Reference Figure 1 and Figure 2 A suspended underwater propeller suitable for seabed operations comprises a through-circular shell 1, inside which support frames 2 are symmetrically installed along the axis direction, between which support frames 2 are installed a rotating shaft 4 through a bearing, and on which a spiral blade 6 is installed.

[0038] A waste removing mechanism 5 is installed on any support frame 2, including: a differential 51, installed on the corresponding support frame 2 and drivingly connected to the rotating shaft 4.

[0039] A rotating shaft 52 is installed on the differential 51 and indirectly drivingly connected to the rotating shaft 4.

[0040] There are multiple shifting rods 53 which are evenly distributed circumferentially along the rotating shaft 52 and automatically open and close at a certain angle.

[0041] Refer to Figure 2 , the support frame 2 is composed of multiple fixing rods 21 evenly distributed circumferentially. Both ends of the fixing rod 21 are jointly installed with a fixing circular plate 22 and an annular circular plate 23 respectively. And the rotating shaft 4 is installed on the fixing circular plate 22 through a bearing. The annular circular plate 23 is installed on the inner wall of the circular shell 1. A plurality of blocking rods 24 evenly distributed circumferentially are arranged between adjacent fixing rods 21 and located between the fixing circular plate 22 and the annular circular plate 23, which are used to block external impurities from entering the inside of the circular shell 1.

[0042] During the rotation of the rotating shaft 52 of the waste removing mechanism 5, through the mutual cooperation with the shifting rod 53, it can actively shift the impurities and the like encountered during the forward movement of the circular shell 1 to the outside of the circular shell 1, thereby effectively removing the impurities in the surrounding water body during the forward movement of the circular shell 1 and reducing the risk of the spiral blade 6 being jammed or even damaged due to impurities entering the inside of the circular shell 1; meanwhile, the blocking rod 24 can passively block the unremoved impurities, so that the active removal and passive blocking cooperate with each other to further reduce the possibility of impurities entering the inside of the circular shell 1.

[0043] Refer to Figure 2 and Figure 3 , a C-shaped frame 25 is installed on the support frame 2 far from the differential 51. A circular through-hole 26 is opened on the C-shaped frame 25. It also includes a traction rope 27 matching the circular through-hole 26, a winding roller 28 for winding the traction rope 27, and a fixed frame 29 for placing the winding roller 28.

[0044] Before the invention is launched into the water, the end of the traction rope 27 far from the winding roller 28 is fixed on the circular through-hole 26 to limit the C-shaped frame 25, thereby hoisting the underwater thruster designed by the invention into the water. Specifically, during operation, the circular shell 1 is fixedly connected to the working equipment and the circular shell 1 and the working equipment are put into the water. Then the fixed frame 29 is installed on the shore. At this time, the rotating shaft 4 is driven to rotate by an external driving force (such as a motor). During the rotation of the rotating shaft 4, the spiral blade 6 is driven to rotate. Then the spiral blade 6 stirs the water to move backward, so that the invention has a forward movement force, and thus can drive the working equipment to move forward. During the forward movement of the working equipment, it can perform operations on the seabed.

[0045] During the operation, the traction rope 27 is synchronously paid out through the winding roller 28 equipped on the mobile device to ensure that the traction rope 27 and the operating equipment always move synchronously. This can effectively avoid the risk of separation and loss of the operating equipment and the circular shell 1 under extreme weather conditions (such as strong winds and waves on the water).

[0046] In addition, when the power source of the operating equipment fails, that is, the spiral blade 6 cannot continue to work, the laid traction rope 27 can be rolled up by the winding roller 28 positioned on the equipment. In this way, the operating equipment and the round shell 1 can be pulled back together, reducing unnecessary equipment damage and economic losses.

[0047] In short, this method not only enhances the stability of the operating equipment in complex environments, but also improves the safety of the equipment and accessories, and can ensure the safe recovery of the operating equipment in the event of power failure.

[0048] The differential 51 can enable the high-speed rotating shaft 4 to provide driving force for the rotating shaft 52 during the rotation process, and the rotation speed of the rotating shaft 52 is much lower than the rotation speed of the rotating shaft 4, thereby reducing the dependence on the external drive device. At the same time, it only relies on the rotating shaft 4 as the power source, further reducing the possibility of additional shaking of the entire invention caused by the use of external drive, thereby improving the stability and working efficiency of the equipment.

[0049] Reference Figure 4 and Figure 5 A connecting block 521 is installed at one end of the rotating shaft 52 away from the differential 51, and the connecting block 521 has a square structure. The toggle rod 53 is installed on the side wall of the connecting block 521 through a spring hinge.

[0050] A connecting rod 522 is symmetrically installed on one side of the circular shell 1 close to the rotating shaft 52, and an annular frame 523 is commonly installed on the two connecting rods 522, and the rotating shaft 52 passes through the annular frame 523, and a limiting rod 524 is symmetrically installed on the annular frame 523, and an annular plate 525 that reciprocates along the length direction of the rotating shaft 52 is slidably penetrated between the two limiting rods 524, and a plurality of circumferentially evenly distributed supporting rods are installed on the circumferential surface of the annular plate 525, and an annular adjustment plate 526 for adjusting the opening and closing angle of the toggle rod 53 is commonly installed on the end of the supporting rod away from the annular plate 525.

[0051] The rotating shaft 52 is provided with a bidirectional thread, and the annular plate 525 cooperates with the bidirectional thread and is installed on the rotating shaft 52 by a threaded connection.

[0052] In the specific working process, the rotation of the rotating shaft 52 drives the bidirectional thread to push the annular plate 525 to move along the direction of the rotating shaft 52. The limiting rod 524 is closely matched with the annular frame 523 to ensure that the annular plate 525 does not rotate with the rotating shaft 52 during the movement, thereby maintaining accurate directional movement.

[0053] When the annular plate 525 moves forward according to the guidance of the two-way thread, it will closely cooperate with the support rod, prompting the annular adjustment plate 526 to move in the direction of the toggle rod 53. Once the annular adjustment plate 526 contacts the toggle rod 53 and applies pressure, the annular adjustment plate 526 will drive the toggle rod 53 to rotate around the spring hinge as it continues to move forward. As the rotation continues, the angle between the toggle rod 53 and the rotating shaft 52 gradually increases. This change causes nearby water plants and other impurities to be forcibly pushed away and removed. In this way, impurities carried in the water flow are effectively removed, reducing the potential risk of impurities entering the circular shell 1 and causing the spiral blade 6 to get stuck or damaged.

[0054] When the annular plate 525 moves to the terminal position of the bidirectional thread section, the rotating shaft 52 causes the annular adjustment plate 526 to reset through the interaction of the bidirectional thread system. During this process, the angle between the toggle rod 53 and the rotating shaft 52 gradually decreases, and the toggle rod 53 is also reset accordingly. When the annular plate 525 moves toward the end close to the differential 51, the entire system repeats the above cleaning action. The toggle rod 53 performs a reciprocating opening and closing action, during which the impurities adhering to the surface can be thrown out through the spring hinge. At the same time, the continuous rotation of the rotating shaft 52 further drives the toggle rod 53 to rotate circumferentially through the connecting block 521, which can continue to remove impurities on the toggle rod 53 and disturb the water flow to generate centrifugal force, effectively throwing out impurities such as water plants around the circular shell 1. This two-pronged cleaning mechanism further reduces the risk of impurities such as water plants entering the interior of the circular shell 1 and affecting the working reliability of the spiral blade 6.

[0055] Reference Figure 4 and Figure 5 A rotating ring 527 is also installed on the rotating shaft 52, and a brush 528 for cleaning the blocking rod 24 is symmetrically installed on the circumferential surface of the rotating ring 527.

[0056] The rotating shaft 52 drives the rotating ring 527 to drive the brush 528 to effectively clean the impurities attached to the blocking rod 24 during the rotation process, preventing the accumulation of impurities around the blocking rod 24, thereby avoiding the inability of the water to generate sufficient convection due to the accumulation of impurities when the rotating blades rotate.

[0057] Reference Figure 2 and Figure 4In order to adapt to the different densities of impurities such as aquatic plants in different waters, the present invention is designed with adjustable spacing of the blocking rods 24: by changing the number and spacing of the blocking rods 24 to adapt to different water quality conditions, specifically, a clamping groove for placing the blocking rod 24 is opened on the fixed circular plate 22 close to the differential 51 and located between adjacent fixed rods 21, and a clamping block 241 is provided on the clamping groove for limiting the blocking rod 24. A clamping groove for placing the blocking rod 24 is also opened on the annular circular plate 23 corresponding to the fixed circular plate 22, and a clamping block 242 is provided on the corresponding clamping groove for limiting the blocking rod 24.

[0058] As shown in the figure, the blocking rods 24 are in the most dense state, and can be deleted as appropriate according to actual needs. In specific work, during use, the user can adjust the number of blocking rods 24 according to the change in the density of water plants. For example, when encountering a situation where water plants are relatively dense, in order to prevent water plants or other impurities in the water area from entering the round shell 1, the user can first remove the clamping block 1 241 and the clamping block 2 242 from the clamping groove, and then increase the number of blocking rods 24 to reduce the distance between every two blocking rods 24, which can greatly reduce the chance of water plants entering the interior of the blocking structure. After the adjustment is completed, the clamping block 1 241 and the clamping block 2 242 are reinstalled back to their original positions to fix the blocking rods 24 in the new position.

[0059] When the water area is sparse with aquatic plants, the operating equipment can travel at a normal speed without slowing down to avoid collision with the aquatic plants. At this time, there is no need to adjust the number of blocking rods 24, and the limiting effect of the clamping block 1 241 and the clamping block 2 242 is maintained to ensure that the blocking rods 24 are arranged in the clamping grooves inside the support frame 2 at the original spacing, thereby effectively blocking the aquatic plants from entering the round shell 1, while ensuring the normal driving efficiency and safety of the operating equipment.

[0060] Such a design can not only improve the safety of underwater operation equipment, but also effectively reduce obstacles in equipment operation and improve work efficiency.

[0061] Reference Figure 2 The side wall of the round shell 1 is provided with a plurality of through grooves 11 evenly distributed in the circumferential direction.

[0062] The design of these through grooves 11 can effectively alleviate the turbulent state of the water flow in the circular shell 1, thereby achieving a pressure relief effect, thereby avoiding the possibility of increased shaking of the circular shell 1 due to the turbulent water flow, and ensuring the stability and safety of the overall structure.

[0063] Embodiment 2:

[0064] Reference Figures 6 to 9On the basis of the first embodiment, the hoisting underwater propulsion device also includes an annular connecting frame 7, on which a fixed connecting block 71 matching with the traction rope 27 is installed, and a plurality of placement grooves 72 evenly distributed in the circumference and matching with the molded frame 25 are opened on the side wall of the annular connecting frame 7, and an annular connecting block 73 is arranged at the center of the annular connecting frame 7, and the annular connecting block 73 is connected to the annular connecting frame 7 through a supporting connecting frame 74 corresponding to the placement grooves 72 one by one.

[0065] A through groove 75 is formed inside the supporting frame 74, a winding shaft 76 is rotatably mounted on the annular connecting block 73 through a bearing, a locking rod 77 matching the round through hole 26 is slidably arranged inside the placement groove 72, a telescopic spring 78 for resetting the locking rod 77 is installed between the locking rod 77 and the through groove 75, a connecting rope 79 is installed at one end of the locking rod 77 located inside the through groove 75, and the end of the connecting rope 79 away from the corresponding locking rod 77 is wound around the winding shaft 76, and a connecting protrusion 70 is installed at one end of the annular connecting block 73 away from the winding shaft 76.

[0066] When it is necessary to drive heavier operating equipment, an appropriate number of round shells 1 are matched with the placement grooves 72 one by one, and then the traction rope 27 is fixed on the fixed connecting block 71, and the present invention is fixedly connected to the operating equipment through the connecting protrusion 70. At this time, the winding shaft 76 is rotated, and the connecting rope 79 is synchronously wound during the rotation of the winding shaft 76. At this time, the locking rod 77 moves along the direction of the through groove 75 and toward one end of the winding shaft 76, and the telescopic spring 78 is stretched. When the locking rod 77 completely enters the through groove 75, the corresponding round shell 1 is locked. The mold frame 25 is inserted into the placement groove 72, and the winding shaft 76 is loosened. At this time, the telescopic spring 78 is reset and the locking rod 77 is reset. The locking rod 77 is just inserted into the round through hole 26 at this time, and then the locking rod 77 fixes the mold frame 25 on the annular connecting frame 7. The locking rod 77 and the connecting rope 79 cooperate with each other to achieve quick locking or release of the mold frame 25, reducing the use of fixing or releasing the mold frame 25. At this time, the annular connecting frame 7 cooperates with each circular shell 1 and the spiral blade 6 to give the operating equipment greater driving force.

[0067] In addition, even if some of the spiral blades 6 on the annular connecting frame 7 are damaged, the remaining spiral blades 6 and the annular connecting frame 7 can still work together to provide driving force for the operating equipment, ensuring that the operating equipment can still move slowly in the case of insufficient power and maintain normal operation.

[0068] The implementation principle of the present invention is:

[0069] (1): The round shell 1 is fixedly connected to the operating equipment and placed in water, and then the fixed frame 29 is installed on the shore. At this time, the rotating shaft 4 is driven to rotate by an external driving force (motor, etc.). During the rotation of the rotating shaft 4, the spiral blade 6 is driven to rotate, which can drive the operating equipment to move forward. During the forward movement of the operating equipment, the operating equipment can be processed on the seabed.

[0070] (2): During the operation, the traction rope 27 is released synchronously by the winding roller 28 equipped on the mobile equipment to ensure that the traction rope 27 and the operating equipment always move synchronously.

[0071] (3): As the rotation continues, the angle between the toggle lever 53 and the rotating shaft 52 gradually increases. This change causes the nearby water plants and other impurities to be forcibly pushed away and removed. When the annular plate 525 moves to the terminal position of the two-way thread segment, the rotating shaft 52 causes the annular adjustment plate 526 to reset through the interaction of the two-way thread system. During this process, the angle between the toggle lever 53 and the rotating shaft 52 gradually decreases, and the toggle lever 53 is also reset. When the annular plate 525 moves toward the end close to the differential 51, the entire system repeats the above cleaning action. The toggle lever 53 performs a reciprocating opening and closing action, during which the impurities adhering to the surface can be thrown out through the spring hinge.

[0072] (4): The rotating shaft 52 drives the rotating ring 527 to drive the brush 528 to effectively clean the impurities attached to the blocking rod 24 during the rotation process, thereby preventing the accumulation of impurities around the blocking rod 24.

[0073] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0074] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
