Description

Technical Field

[0001] This invention relates to the field of robotics, and more specifically to a robot lifting and positioning device. Background Technology

[0002] ROVs / AUVs are key equipment in marine exploration, underwater operations, aquaculture, and underwater facility maintenance. To ensure continuous underwater operation over extended periods and large areas, they typically require a composite cable (integrating power supply, data transmission, and other functions) to connect to a surface or shore-based control station. The cable's deployment and retrieval mechanism (winch) is one of the core devices controlling the robot's underwater depth and position. It not only needs to enable rapid ascent and descent and precise positioning of the robot but also must properly handle the large amounts of water adhering to the cable during entry and exit to prevent equipment corrosion, electrical short circuits, and pollution of the control cabin environment.

[0003] In the prior art, Chinese Patent Publication No. CN223573632U discloses a rapid lifting and positioning device for an underwater robot. This device elevates the robot body by placing a reel on the water surface and using a drive motor to wind and unwind a steel cable, managing the power cord through an independent winding post. To address the issue of water residue on the power cord when it emerges from the water, the device incorporates an absorbent sponge inside the first cable threading hole of the separation plate, intended to wipe away surface water stains during power cord retrieval.

[0004] However, in practical applications, absorbent sponges can easily exceed their physical adsorption limit in a short period of time, resulting in incomplete water removal. Residual water stains can still contaminate the equipment platform and pose electrical safety hazards. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] In the above description of the present invention, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is conventionally placed during use. These terms are used only for the convenience of describing the present invention and for 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. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0025] Please see Figure 1-5 This invention provides a technical solution: a robot lifting and positioning device, including a fixed base 1 and a robot body 2. The fixed base 1 is provided with a winding mechanism 3 and a mounting frame 4. The winding mechanism 3 is used to wind and unwind a power cord 5 and a wire rope 51. The other end of the power cord 5 is connected to the robot body 2, and the other end of the wire rope 51 is fixed to the robot body 2. Both the power cord 5 and the wire rope 51 pass around the mounting frame 4, and the mounting frame 4 has a threading hole 41 for the wire rope 51 to pass through. A meter counter 42 is provided in the threading hole 41. The lifting and positioning device also includes: Except for the water tank 6, which is installed on the mounting bracket 4, its opposite side walls are respectively provided with an inlet hole 61 and an outlet hole 62 for the power cord 5 to enter. The wiper assembly 7 is fixed to the side of the water tank 6 where the inlet hole 61 is provided, and the wiper assembly 7 has a wiper hole 73 for wiping the power cord 5. The water absorption assembly 8 is installed in the water removal tank 6 and is provided with a water absorption hole 86 for absorbing water from the power cord 5. The drying assembly 9 is installed in the water tank 6 and blows warm air toward the power cord 5.

[0026] During the underwater robot's recovery process, its power cable 5 carries a large amount of seawater. The squeegee assembly 7, the suction assembly 8, and the water-absorbing assembly 9 sequentially treat the water adhering to the power cable 5. Specifically, the squeegee assembly 7 mechanically scrapes away most of the adhering water from the surface of the power cable 5 through its squeegee holes 73; subsequently, the suction assembly 8 deeply absorbs any remaining fine water droplets and moisture through its suction holes 86; finally, the warm air blown by the drying assembly 9 provides final drying of the power cable 5 and accelerates moisture evaporation, ensuring that even after deep-water operations, the power cable 5 remains highly dry before being wound up and stored, fundamentally preventing equipment corrosion, electrical short circuits, and environmental pollution in the control cabin.

[0027] By setting a meter counter 42, it is easy to monitor the unwinding length of the wire rope 51, thereby enabling precise positioning of the robot body 2.

[0028] Based on the above embodiments, the winding mechanism 3 includes two vertical plates 31, a drive shaft 32 movably connected to the two vertical plates 31 at both ends, a winding reel 33 connected to the middle end of the drive shaft 32, and a drive motor 34 fixed to one of the vertical plates 31 and driven by a drive motor connected to one end of the drive shaft 32. The segments of the drive shaft 32 located on both sides of the winding reel 33 are used for winding and unwinding the power cord 5 and the wire rope 51, respectively.

[0029] Furthermore, a sponge sleeve 321 is provided on the outer surface of the drive shaft 32 on the side of the take-up reel 33 to protect the power cord 5, prevent the power cord 5 from making hard contact with the drive shaft 32, and facilitate the operation of the power cord 5.

[0030] A winding wheel (not shown in the diagram) is fixed on the mounting bracket 4. The power cord 5 and the steel wire rope 51 both pass around the winding wheel.

[0031] In this embodiment: Please refer to Figure 5 The drying assembly 9 includes a heater 91 installed in the water tank 6 and a blower pipe 92 with one end connected to the air outlet of the heater 91, the blower pipe 92 facing the power cord 5.

[0032] The warm air generated by the heater 91 is precisely and centrally guided and blown onto the surface of the power cord 5 after pretreatment by the wiper assembly 7 and the absorbent assembly 8 through the blower 92. This achieves active drying of the power cord 5 and can effectively evaporate the trace amounts of moisture remaining in the gaps on the surface of the power cord 5 or that were not completely removed by the first absorbent layer 833 and the second absorbent layer 843 of the absorbent material. This ensures that the power cord 5 is thoroughly dry before being rolled up and stored, fundamentally eliminating problems such as internal corrosion, reduced electrical insulation, or microbial growth caused by residual water stains.

[0033] In this embodiment: Please refer to Figure 5 and Figure 6 The wiper assembly 7 includes a cantilever 71 fixedly connected to the water tank 6 at one end and a wiper blade 72 connected to the other end of the cantilever 71. The wiper blade 72 has wiper holes 73.

[0034] The wiper blade 72 includes two opposing pressure plates 721, a flexible layer 722 disposed on one side of the two pressure plates 721, and a locking member 723 that is locked to both pressure plates 721. Both pressure plates 721 are provided with sliding holes 7211. The other end of the cantilever 71 is adapted to and slidably connected to the sliding holes 7211 so that the two pressure plates 721 can move towards or away from each other. The two pressure plates 721 and the flexible layer 722 together form a wiper hole 73.

[0035] In use, the two pressure plates 721 can scrape away most of the water from the power cord 5. By setting the scraper 72 to slide along the cantilever 71 within the sliding hole 7211 and locking the two pressure plates 721 with the locking member 723, the assembly can be flexibly adjusted according to the power cord 5 of different diameters or changes due to wear, always ensuring a suitable squeezing contact with the power cord 5. This not only achieves efficient scraping away of a large amount of water adhering to the surface of the power cord 5, but its adjustable and detachable structure also greatly facilitates the replacement and maintenance of the components.

[0036] In this embodiment: Please refer to Figure 5-12 In addition to the water tank 6, both sides of the opposite side walls are provided with clearance holes 63; The water-absorbing component 8 includes: Two sets of sliding plates 81 are fixedly connected to the outer sides of the opposite side walls of the water tank 6, and the sliding plates 81 extend along the opening direction of the clearance hole 63. Two sets of adjusting components 82 are slidably connected to two sets of sliding plates 81, so that one end of the adjusting component 82 can enter and exit the water tank 6 through the clearance hole 63; A first arc-shaped clamping plate 83 is connected to one end of one set of adjusting members 82; and The second arc-shaped clamping plate 84 is connected to one end of another set of adjusting members 82; the first arc-shaped clamping plate 83 and the second arc-shaped clamping plate 84 are bent towards each other and enclosed to form a water absorption hole 86. The inner side of the first arc-shaped clamping plate 83 is connected to the first water absorption layer 833, and the inner side of the second arc-shaped clamping plate 84 is connected to the second water absorption layer 843.

[0037] By setting an adjustable member 82 that can move along the slide plate 81, the first arc-shaped clamping plate 83 and the second arc-shaped clamping plate 84 connected to its end can move flexibly and precisely towards or away from each other, thereby enclosing and controlling the size of the formed water absorption hole 86. This allows the water absorption assembly 8 to adapt to power cables 5 of different diameters or those deformed due to use, ensuring that the first water absorption layer 833 and the second water absorption layer 843 can always contact the cable surface with the optimal adhesion pressure. This achieves efficient and uniform wrapping water absorption of the cable from both sides, avoiding water leakage caused by excessive gaps or insufficient water absorption caused by uneven pressure.

[0038] When the absorbent layer becomes saturated, its performance deteriorates, or it needs cleaning due to long-term use, simply slide the adjusting piece 82 from the outside. The first arc-shaped clamping plate 83, the second arc-shaped clamping plate 84, the first absorbent layer 833, and the second absorbent layer 843 can be pulled out as a whole from the side of the water tank 6 through the clearance hole 63, so that the first absorbent layer 833 and the second absorbent layer 843 can be replaced.

[0039] The first arc-shaped clamping plate 83 includes a first rotating shaft 831 and two first arc-shaped plates 832, with one end of the two first arc-shaped plates 832 rotatably connected through the first rotating shaft 831; the second arc-shaped clamping plate 84 includes a second rotating shaft 841 and two second arc-shaped plates 842, with one end of the two second arc-shaped plates 842 rotatably connected through the second rotating shaft 841. The adjusting component 82 includes an adjusting column 821, a first adjusting plate 822, a second adjusting plate 823, and a linear telescopic component 824. The end of the adjusting column 821 is slidably connected to the sliding plate 81. One end of the first adjusting plate 822 and the second adjusting plate 823 are respectively rotatably connected to the two ends of the adjusting column 821. The middle ends of the first adjusting plate 822 and the second adjusting plate 823 intersect each other. The other end of one set of the first adjusting plate 822 and the second adjusting plate 823 is respectively rotatably connected to two first arc-shaped plates 832, and the other end of the other set of the first adjusting plate 822 and the second adjusting plate 823 is respectively rotatably connected to two second arc-shaped plates 842. The two ends of the linear telescopic component 824 are respectively rotatably connected to one end of the first adjusting plate 822 and the second adjusting plate 823.

[0040] The telescopic movement of the linear telescopic component 824 can be converted into an angular change between the first adjusting plate 822 and the second adjusting plate 823, thereby controlling the rotation of the two first arc-shaped plates 832 around the first rotating shaft 831 and the rotation of the two second arc-shaped plates 842 around the second rotating shaft 841. When the diameter of the power cord 5 changes or irregular wear occurs due to long-term use, the operator or control system can steplessly adjust the diameter of the water absorption hole 86 formed by the first arc-shaped plate 832 and the second arc-shaped plate 842 by controlling the telescopic amount of the linear telescopic component 824, ensuring that the first water absorption layer 833 and the second water absorption layer 843 can fit the cables of different diameters with optimal pressure, achieving efficient and damage-free wrapping water absorption.

[0041] Based on the above embodiments, the first adjusting plate 822 has a cross hole 8221 for the second adjusting plate 823 to move.

[0042] The linear telescopic component 824 includes a sleeve rod 8241 and two screw rods 8242. One end of each screw rod 8242 is threaded to both ends of the sleeve rod 8241, and the other ends of each screw rod 8242 are rotatably connected to the first adjusting plate 822 and the second adjusting plate 823 via U-shaped seats.

[0043] In this embodiment: Please refer to Figure 5 and Figure 7The adjusting column 821 includes a slide block 8211 slidably connected to the slide block 81, a connecting plate 8212 rotatably connected to the slide block 8211 at one end, a first adjusting shaft 8213 fixedly connected to one end of the connecting plate 8212, and a second adjusting shaft 8214 fixedly connected to the other end of the connecting plate 8212; the first adjusting plate 822 is rotatably connected to the first adjusting shaft 8213, and the second adjusting plate 823 is rotatably connected to the second adjusting shaft 8214.

[0044] When maintenance personnel pull the entire adjusting component 82 out along the slide plate 81 via the slide block 8211, disengaging it from the clearance hole 63 of the water removal tank 6, they can manually rotate the connecting plate 8212. This causes the first adjusting shaft 8213 and the second adjusting shaft 8214 fixed at both ends to rotate synchronously. Consequently, the first adjusting plate 822, the second adjusting plate 823 connected to it, and the entire first arc-shaped clamping plate 83 and the second arc-shaped clamping plate 84 assembly driven by them change orientation. This allows the first absorbent layer 833 and the second absorbent layer 843, which were originally facing the working position inside the water removal tank 6, to rotate and move away from the water removal tank 6. This exposes the first absorbent layer 833 and the second absorbent layer 843, which need to be replaced or cleaned, to the most convenient position for the operator to operate in front of them, eliminating the need for the operator to reach into the narrow interior of the tank, thus significantly simplifying the maintenance process.

[0045] The water absorption assembly 8 also includes a drive rod 85 threadedly connected to the slide 8211. The drive rod 85 extends along the length of the slide plate 81 and is rotatably connected to the slide 8211.

[0046] By rotating the drive rod 85, the entire adjusting component 82, which carries the first arc-shaped clamping plate 83 and the second arc-shaped clamping plate 84, can be accurately moved and fixed in the preset optimal working position of the water tank 6, ensuring that the water suction hole 86 formed by the first arc-shaped plate 832 and the second arc-shaped plate 842 can be accurately aligned and wrap around the power cord 5. The self-locking characteristic of the drive rod 85 can effectively prevent the slide block 8211 from accidentally shifting due to cable friction or vibration during the water suction operation, thereby ensuring the positional accuracy and clamping force stability of the water suction assembly 8 during long-term operation.

[0047] When it is necessary to pull out the entire water absorption assembly 8 for maintenance, such as replacing the first water absorption layer 833 and the second water absorption layer 843, the operator can directly hold and rotate the drive rod 85 to smoothly remove the slide 8211 from the working position using the threaded transmission; after maintenance is completed, the drive rod 85 can be rotated in the opposite direction to smoothly and accurately push the module back to the working position.

[0048] In this embodiment: Please refer to Figure 8-12The other end of each of the two first arc-shaped plates 832 is provided with a slot 8321. The slot wall of the slot 8321 is provided with a first inclined surface 8322 and a second inclined surface 8323. The first inclined surface 8322 is located at the opening of the slot 8321, and the second inclined surface 8323 is located at the bottom of the slot 8321. The inclination directions of the first inclined surface 8322 and the second inclined surface 8323 are opposite. The other ends of the two second arc-shaped plates 842 can be inserted into the corresponding slots 8321; the other ends of the two second arc-shaped plates 842 are provided with elastic members 8421 that can abut against the first inclined surface 8322 or the second inclined surface 8323.

[0049] When the first arc-shaped plate 832 and the second arc-shaped plate 842 move towards each other under the drive of the adjusting member 82, the elastic member 8421 at the other end of the second arc-shaped plate 842 will first contact and slide along the first inclined surface 8322 at the opening of the slot 8321. The guiding effect of the first inclined surface 8322 can automatically correct the lateral positional deviation of the two arc-shaped plates during the closing process and guide them to be accurately aligned. As the closing action continues, after the elastic member 8421 slides past the first inclined surface 8322, it will finally abut against and press against the second inclined surface 8323 at the bottom of the slot 8321. Since the first inclined surface 8322 and the second inclined surface 8323 have opposite inclination directions, when in the fully closed position, the elastic element 8421 generates a radial component force on the second inclined surface 8323 that presses the first arc plate 832 and the second arc plate 842 together, thereby ensuring that the water absorption hole 86 formed by them has a tight profile and effectively prevents water from leaking from the joint between the first arc plate 832 and the second arc plate 842 when clamping the cable.

[0050] In this embodiment: the end of the second arc plate 842 is provided with an elastic groove; the elastic element 8421 includes a spring 84211 disposed in the elastic groove and a hanging rod 84212 with one end abutting against the spring 84211, and the hanging rod 84212 can abut against the first inclined surface 8322 or the second inclined surface 8323.

[0051] During the opening and closing process of the first arc plate 832 and the second arc plate 842, the end of the hanging rod 84212 contacts and slides against the first inclined surface 8322 or the second inclined surface 8323, and the spring 84211 adaptively contracts. When the first arc plate 832 separates from the second arc plate 842, the hanging rod 84212 slides from the second inclined surface 8323 to the first inclined surface 8322 and slides out of the slot 8321.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
