[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, the underwater robot umbilical cable holder provided in this embodiment of the present invention includes a base 21. A locking component 6 is provided on one side of the base 21. The locking component 6 includes a base plate 61 welded to one side of the base 21. A gear 62 is rotatably connected to one side of the base plate 61. A groove 63 is provided on the top of the gear 62. A top pin 64 is slidably connected between the base plate 61 and the gear 62. A limit post 65 is welded to the top of the top pin 64. The limit post 65 is located in the groove 63. A gear 66 is provided on one side of the base 21. The gear 66 meshes with the gear 62. A servo motor 67 is provided on one side of the gear 66.

[0026] In this embodiment, a base 21 is included. The base 21 is a cylindrical flat plate and is set horizontally. It is made of high-strength aluminum alloy, which takes into account both lightweight and structural strength. A locking component 6 is provided on one side of the base 21. The locking component 6 includes a base plate 61 welded to one side of the base 21. The base plate 61 serves as the supporting base of the locking component 6 and is vertically fixed to the left edge of the base 21 by welding. The welded joint is polished and rust-proofed to ensure connection strength and durability.

[0027] A gear disk 62 is rotatably connected to one side of the base plate 61. The gear disk 62 is circular in shape, and its center is rotatably connected to the base plate 61 through a deep groove ball bearing. The inner ring of the bearing is interference-fitted with the central axis of the gear disk 62, and the outer ring is tightly fitted with the mounting hole on the base plate 61, so that the gear disk 62 can rotate flexibly on the base plate 61 around its own axis.

[0028] The top of the toothed disc 62 is provided with a groove 63, and both sides of the top of the toothed disc 62 are provided with grooves 63. The grooves 63 are V-shaped and are used to cooperate with the limiting post 65 to achieve positioning and locking.

[0029] A top pin 64 is slidably connected between the base plate 61 and the gear plate 62. The top pin 64 is a rectangular rod. A groove is provided on the base plate 61. The top pin 64 is slidably connected to the base plate 61 through the groove. A limit post 65 is welded to the top of the top pin 64. The limit post 65 is located in the groove 63. The shape of the limit post 65 is adapted to the groove 63. When the top pin 64 moves upward, the limit post 65 slides in the groove 63, restricting the movement trajectory of the top pin 64.

[0030] A gear 66 is provided on one side of the base 21. The gear 66 meshes with the gear disk 62. A servo motor 67 is provided on one side of the gear 66. The gear 66 is mounted on the side of the base 21, located on the same plane as the gear disk 62 and meshing with each other. The central shaft of the gear 66 is fixed on the base 21 by a bearing seat to ensure its stable rotation. The servo motor 67 is bolted to the side of the protective cover 3. Its output shaft is keyed to the central shaft of the gear 66. When the servo motor 67 is powered on, it can drive the gear 66 to rotate, thereby driving the gear disk 62 to rotate.

[0031] When it is necessary to fix the umbilical cable 41, the servo motor 67 drives the gear 66 to rotate, which in turn drives the gear plate 62 to rotate. The limiting post 65 slides along the groove 63, which drives the top pin 64 to move, thereby fixing the umbilical cable 41. When unlocking, the servo motor 67 reverses to contact and lock.

[0032] Specifically, the robot body 1 is provided on the other side of the base 21. The two are detachably connected by locking nut 22. The robot body 1 has a connection port 11 inside. The connection port 11 is a standard electrical interface for connecting the plug 42 on the umbilical cable 41.

[0033] Specifically, several locking nuts 22 are distributed around the periphery of the base 21. The locking nuts 22 are used to fix the robot body 1. Four bases are evenly distributed on the right edge of the base 21. A through hole is opened at the corresponding position on the bottom of the robot body 1. The locking nuts 22 are screwed into the threaded hole of the base 21 through the through hole of the base and the robot body 1, so as to firmly fix the robot body 1 on the base 21.

[0034] Furthermore, a protective cover 3 is threadedly connected to one side of the base 21. The protective cover 3 has a cylindrical shell structure and is threadedly connected to the base 21 by bolts, covering the connection port 11 of the robot body 1 and part of the internal structure to prevent dust, moisture and other substances from entering.

[0035] Furthermore, a wiring harness assembly 4 is provided on one side of the base 21. The wiring harness assembly 4 includes a plug 42 that is inserted into the connection port 11. The plug 42 is a cylindrical connector that is plugged into and unplugged into the connection port 11 inside the robot body 1. An umbilical cable 41 is provided on one side of the plug 42. The umbilical cable 41 is a multi-core composite cable. One end is injection molded and connected to the plug 42, and the other end extends to an external device. The umbilical cable 41 is fixed by a locking assembly 6.

[0036] It should be noted that the outer wall of the umbilical cable 41 is provided with a sealing component 5. The sealing component 5 includes an annular airbag 51 sleeved on the outer wall of the umbilical cable 41. The annular airbag 51 is a hollow rubber ring with an inner diameter slightly smaller than the outer diameter of the umbilical cable 41. It is tightly sleeved on the outer wall of the umbilical cable 41 by interference fit. The outer wall of the annular airbag 51 is provided with an inflation nozzle 52. The inflation nozzle 52 is a one-way valve structure and is connected to an external air source through an air tube.

[0037] When in use, air is inflated into the annular airbag 51. After the airbag expands, it adheres tightly to the surface of the umbilical cable 41 and the surrounding structure, forming a sealing layer that effectively isolates the external environment.

[0038] Working steps: 1. Pass the umbilical cable 41 through the locking assembly 6, so that the plug 42 at one end of the umbilical cable 41 is inserted into the connection port 11 inside the robot body 1.

[0039] 2. The umbilical cable 41 is locked and fixed by adjusting components such as the toothed disc 62 in the locking assembly 6 of the mechanism;

[0040] 3. A ring-shaped airbag 51 is fitted onto the outer wall of the umbilical cord cable 41. The ring-shaped airbag 51 is inflated through the air inlet 52 to make it fit tightly against the outer wall of the umbilical cord cable 41, forming a seal to prevent water from seeping in.

[0041] 4. During disassembly, deflate the annular airbag 51 and drive the servo motor 67 to flip it over, releasing the lock on the umbilical cable 41. Then, unplug the plug 42 and remove it.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
