Description

Technical Field

[0001] This utility model relates to the field of signal transceiver equipment technology, specifically a signal transceiver device for underwater robots. Background Technology

[0002] Underwater robots, also known as remotely operated vehicles (ROVs), are robots designed for extreme underwater operations. Given the harsh and dangerous underwater environment and the limited diving depth of humans, underwater robots have become crucial tools for ocean exploration. Signal transceivers are key components for communication between underwater robots and the outside world, responsible for transmitting control commands and sending back detection data. The harsh underwater environment often causes moisture and corrosion to the internal electronic components, leading to malfunctions. When signal delays or interruptions occur, technicians must frequently disassemble and reassemble the device for comprehensive internal inspection and repair to restore normal operation. However, to ensure the signal transceiver is securely mounted on the underwater robot, numerous bolts are required for connection. Therefore, during disassembly and reassembly, workers must manually remove each bolt, which is time-consuming and labor-intensive.

[0003] To address the above problems, this utility model proposes a signal transceiver device for underwater robots. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a signal transceiver device for underwater robots.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a signal transceiver device for underwater robots, including an outer block and a signal transceiver body installed inside the outer block. One end of the outer block is connected to a mounting assembly. The mounting assembly includes a mounting plate fixedly connected to one end of the outer block. An external receiving plate is provided at the end of the mounting plate away from the outer block. A drive gear is rotatably connected to the outer wall of the external receiving plate. Multiple sets of driven gears are meshed with the outer wall of the drive gear. A bolt assembly is provided on the inner wall of each set of driven gears.

[0006] Furthermore, a central connecting rod is fixedly connected to the inner wall of the drive gear. The central connecting rod passes through the center of the outer connecting plate, and a servo motor is fixedly connected to one end of the central connecting rod that passes through the outer connecting plate. The servo motor is fixedly connected to the outer wall of the mounting plate. When the servo motor is started, the rotor inside the motor rotates, which drives the central connecting rod connected to it to rotate, thereby driving the drive gear to rotate. The outer wall of the drive gear meshes with multiple sets of driven gears. According to the gear meshing principle, the rotation of the drive gear drives multiple sets of driven gears to rotate synchronously.

[0007] Furthermore, the driven gear is provided in multiple sets, and the multiple sets of driven gears are evenly distributed around the outer wall of the driving gear.

[0008] Furthermore, the bolt assembly includes an external rod fixedly connected to the inner wall of the driven gear, and the inner wall of the external rod is threaded with an internal bolt.

[0009] Furthermore, the external rod passes through the external mounting plate, and the outer wall of the mounting plate has a threaded hole that matches the inner bolt. The end of the inner bolt away from the mounting plate is threadedly connected to the preset connection port of the underwater robot.

[0010] Furthermore, the inner bolt is always threadedly connected to the mounting plate through the threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model include: during installation, the servo motor starts, driving the connected intermediate rod to rotate, which in turn drives the fixedly connected drive gear to rotate. The rotation of the drive gear causes multiple sets of driven gears to rotate synchronously, and the outer rod on the inner wall of each set of driven gears rotates accordingly. Under the action of the thread, the inner bolt moves along the axial direction of the outer rod and gradually screws into the preset connection port of the underwater robot, completing the installation of the signal transceiver device. When it is necessary to disassemble the device, the servo motor reverses, driving the drive gear to rotate in the opposite direction, which in turn causes the driven gear and the outer rod to rotate in the opposite direction. Under the action of the thread, the inner bolt is screwed out from the preset connection port of the underwater robot, completing the disassembly process. By driving the gear transmission structure through the servo motor, multiple sets of bolt assemblies move synchronously, which improves the disassembly and assembly efficiency of the signal transceiver device compared with the traditional method of operating multiple bolts one by one.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] Please see Figures 1-4 To address the issue of the need for numerous bolts to securely mount the signal transceiver on the underwater robot, requiring workers to manually remove each bolt during assembly and disassembly—a time-consuming and labor-intensive process—the following preferred technical solution is provided:

[0021] A signal transceiver device for an underwater robot includes an outer casing 1 and a signal transceiver body 2 installed inside the outer casing 1. One end of the outer casing 1 is connected to a mounting assembly 3. The mounting assembly 3 includes a mounting plate 31 fixedly connected to one end of the outer casing 1. An outer receiving plate 32 is provided at the end of the mounting plate 31 away from the outer casing 1. A drive gear 33 is rotatably connected to the outer wall of the outer receiving plate 32. Multiple sets of driven gears 34 are meshed with the outer wall of the drive gear 33. Each set of driven gears 34 has a bolt assembly 35 on its inner wall. A central connecting rod 36 is fixedly connected to the inner wall of the drive gear 33, passing through the center of the outer receiving plate 32, and the central connecting rod 36 is fixedly connected to one end of the outer receiving plate 32. A servo motor 37 is fixedly connected to the outer wall of the mounting plate 31. Multiple sets of driven gears 34 are provided, and the multiple sets of driven gears 34 are evenly distributed around the outer wall of the driving gear 33. When the servo motor 37 is started, the rotor inside the motor rotates, which drives the connected intermediate rod 36 to rotate, driving the driving gear 33 to rotate. The outer wall of the driving gear 33 meshes with the multiple sets of driven gears 34. According to the gear meshing principle, the rotation of the driving gear 33 drives the multiple sets of driven gears 34 to rotate synchronously. The multiple sets of driven gears 34 are evenly distributed around the outer wall of the driving gear 33 to ensure uniform force transmission and provide a guarantee for the synchronous operation of the multiple sets of bolt assemblies 35.

[0022] The bolt assembly 35 includes an outer rod 351 fixedly connected to the inner wall of the driven gear 34. An inner bolt 352 is threaded onto the inner wall of the outer rod 351. The outer rod 351 passes through the outer mounting plate 32. A threaded hole matching the inner bolt 352 is formed on the outer wall of the mounting plate 31. The end of the inner bolt 352 furthest from the mounting plate 31 is threadedly connected to a pre-set connection port of the underwater robot. The inner bolt 352 is always threadedly connected to the mounting plate 31 through the threaded hole. When the servo motor 37 is started, the power output by the motor is transmitted through a gear transmission structure, driving the outer rod 351 to rotate. The inner bolt 352 is threadedly connected to the outer rod 351. Under the action of the thread, the inner bolt 352 moves axially along the outer rod 351 and screws the end away from the mounting plate 31 into the preset connection port of the underwater robot to complete the installation. When disassembling, the servo motor 37 reverses, and the inner bolt 352 is screwed out from the preset connection port of the underwater robot and returns to the vicinity of the mounting plate 31 through the threaded hole to complete the disassembly. The inner bolt 352 is always threadedly connected to the mounting plate 31 through the threaded hole to ensure that the bolt assembly 35 will not be lost when the device is not installed on the underwater robot, which facilitates the next installation operation.

[0023] Specifically, during installation, the servo motor 37 starts, driving the connected intermediate rod 36 to rotate. The intermediate rod 36 then drives the fixedly connected drive gear 33 to rotate. Since the drive gear 33 meshes with multiple sets of driven gears 34, the rotation of the drive gear 33 causes the multiple sets of driven gears 34 to rotate synchronously. The outer rod 351 on the inner wall of each set of driven gears 34 rotates accordingly. Because the outer rod 351 is threadedly connected to the inner bolt 352, the inner bolt 352 moves axially along the outer rod 351 under the action of the thread, gradually screwing into the preset connection port of the underwater robot, completing the installation of the signal transceiver device. When it is necessary to disassemble the device, the servo motor 37 reverses... The rotation causes the drive gear 33 to rotate in the opposite direction, which in turn causes the driven gear 34 and the external rod 351 to rotate in the opposite direction. The inner bolt 352, under the action of the thread, unscrews from the preset connection port of the underwater robot and returns to the vicinity of the mounting plate 31, completing the disassembly process. The servo motor 37 drives the gear transmission structure, which drives multiple bolt assemblies 35 to move synchronously. Compared with the traditional method of operating multiple bolts one by one, the disassembly and assembly efficiency of the signal transceiver device is improved. It solves the problem that in order to ensure that the signal transceiver device is stably installed on the underwater robot, a large number of bolts are required for connection. Therefore, during the disassembly and assembly operation, the staff has to operate each bolt one by one, which is time-consuming and laborious.
