Underwater robots have achieved significant practical results in areas such as marine resource exploration, underwater rescue, and seabed topography research. The ability of underwater robots to perceive their environment is currently a key aspect of underwater robot research. Therefore, exploring underwater robots' perception of the underwater environment can provide important information about water flow conditions, helping to guide underwater vehicles to more accurately complete underwater exploration tasks.

[0003] Existing underwater maintenance robots, when their transparent protective shields become severely dirty, can only be lifted to the surface for cleaning, and then lowered back down to continue inspections. This process is not only time-consuming and labor-intensive, but also interrupts inspection work, reduces overall efficiency, and increases operating costs, failing to meet the demands for efficient and continuous underwater maintenance. Therefore, an underwater maintenance robot is needed to help solve this problem. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an underwater maintenance robot to solve the technical problem that existing underwater maintenance robots, when their transparent protective covers become severely dirty, can only be lifted to the surface for cleaning and then returned to the seabed for continued inspection. This process not only consumes a lot of time and manpower, but also interrupts the inspection work, reduces overall work efficiency, and increases operating costs, failing to meet the technical requirements for efficient and continuous underwater maintenance work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an underwater maintenance robot, including a mounting frame, a support frame symmetrically mounted on the bottom of the mounting frame, second propellers symmetrically mounted on both sides of the support frame, a first propeller mounted between the two second propellers on the same side, and the first propeller and the second propellers driving the water flow in different directions;

[0006] The mounting frame is symmetrically equipped with snap-fit ​​components at the top, and mounting posts are mounted on the snap-fit ​​components. The mounting frame is equipped with a mounting ring at the bottom, and a mounting box is mounted on the mounting ring. The front end of the mounting box is equipped with an auxiliary detection camera and sensor. The front end of the mounting box is equipped with a transparent protective cover, and a cleaning component for cleaning the outer edge of the transparent protective cover is installed at the outer edge of the transparent protective cover.

[0007] The present invention is further configured such that the cleaning component includes a cleaning rod, both ends of which are fixed with hinge seats, the hinge seats are rotatably embedded in the transparent protective cover, a cleaning motor that drives the hinge seats to rotate is installed on the inner side of the transparent protective cover, the cleaning rod has a semi-circular rod-shaped structure, and a cleaning brush is embedded in the inner side of the cleaning rod.

[0008] The present invention is further configured such that the transparent protective cover is hemispherical and transparent.

[0009] The present invention is further configured such that a snap-fit ​​ring is fixed at one end of the transparent protective cover, the snap-fit ​​ring has a fixing hole, the fixing hole is fixed to the mounting box by bolts, and a sealing gasket is embedded on the inner side of the snap-fit ​​ring.

[0010] The present invention is further configured such that the snap-fit ​​assembly includes a first fixing ring and a second fixing ring, the first fixing ring and the second fixing ring are fixed by hinge, a fixing ear is fixed on an adjacent side of the first fixing ring and the second fixing ring, a fixing cavity is provided on the fixing ear, and a fixing component for auxiliary fixing is installed in the fixing cavity.

[0011] The present invention is further configured such that the fixing component includes a mounting seat hinged in the fixing cavity, a lead screw protruding from the mounting seat, a clamping sleeve threadedly mounted on the lead screw, the lead screw and the clamping sleeve being threadedly engaged, and the bottom of the clamping sleeve pressing against the top of the top fixing ear.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] An underwater maintenance robot, such as Figure 1-4 As shown, the device includes a mounting frame 1, a support frame 2 symmetrically mounted on the bottom of the mounting frame 1, second propellers 4 symmetrically mounted on both sides of the support frame 2, and a first propeller 3 mounted between the two second propellers 4 on the same side. The first propeller 3 and the second propeller 4 drive the water flow in different directions.

[0022] The underwater maintenance robot is endowed with excellent mobility through its design, which uses several first propellers 3 and second propellers 4 arranged symmetrically and in different directions to drive the water flow. In complex underwater structures, such as waters filled with reefs, shipwrecks, or pipeline networks, the robot can achieve flexible movement in multiple directions by precisely controlling the speed and direction of different propellers.

[0023] The mounting bracket 1 has a mounting ring at its bottom, and a mounting box is mounted on the mounting ring. During operation, the mounting box contains a power supply. An auxiliary detection camera and sensor are located at the front of the mounting box. The sensor can be a sonar sensor, a lidar sensor, or a camera sensor. The sonar sensor can be a 4125 side-scan sonar sensor, the lidar sensor can be a VLP-16 mechanical lidar, and the camera sensor can be an FCB-EV7520 visible light camera. A transparent protective cover 13 is mounted at the front of the mounting box. The transparent protective cover 13 is hemispherical and allows light to pass through. The transparent protective cover 13 has a snap-fit ​​ring 131 fixed to one end. The snap-fit ​​ring 131 has a fixing hole 132. The fixing hole 132 is fixed to the mounting box by bolts. A sealing gasket is embedded in the inner side of the snap-fit ​​ring 131. The fixing hole 132 on the snap-fit ​​ring 131 securely fixes the transparent protective cover 13 to the mounting box by bolts. The sealing gasket embedded in the inner side of the snap-fit ​​ring 131 enhances the sealing performance, effectively preventing water from entering the interior of the mounting box and avoiding damage to the internal electronic equipment due to moisture, thereby extending the service life of the entire underwater maintenance robot.

[0024] A cleaning component 14 for assisting in cleaning the outer edge of the transparent protective cover 13 is installed at the outer edge of the transparent protective cover 13. The cleaning component 14 includes a cleaning rod 15, and both ends of the cleaning rod 15 are fixed with hinge seats 16. The hinge seats 16 are rotatably embedded in the transparent protective cover 13. A cleaning motor that drives the hinge seats 16 to rotate is installed on the inner side of the transparent protective cover 13. The cleaning rod 15 has a semi-circular rod structure, and a cleaning brush 151 is embedded in the inner side of the cleaning rod 15.

[0025] The cleaning component 14, with its semi-circular rod-shaped cleaning rod 15, along with its inner cleaning brush 151, can thoroughly clean the outer edge of the transparent protective cover 13 without any blind spots. This prevents dirt and impurities adhering to the outer edge of the transparent protective cover 13 from being removed, thus avoiding the need to effectively clean the transparent protective cover 13 when dirt appears during seabed inspections. This also prevents the underwater maintenance robot from having to be hoisted up for cleaning and re-inspection due to dirt, thereby improving overall work efficiency.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, a snap-fit ​​assembly 6 is symmetrically installed at the top of the mounting bracket 1. A mounting post 5 is installed on the snap-fit ​​assembly 6. The snap-fit ​​assembly 6 includes a first fixing ring 7 and a second fixing ring 71. Both ends of the second fixing ring 71 are fixed with protruding ears 72. The protruding ears 72 are provided with mounting holes. The first fixing ring 7 and the second fixing ring 71 are fixed by hinges. A fixing ear 8 is fixed on the side adjacent to the first fixing ring 7 and the second fixing ring 71. A fixing cavity is provided on the fixing ear 8. An auxiliary fixing assembly 9 is installed in the fixing cavity. The fixing assembly 9 includes a mounting seat 10 hinged in the fixing cavity. A lead screw 11 is protruding on the mounting seat 10. A clamping sleeve 12 is threaded on the lead screw 11. The lead screw 11 and the clamping sleeve 12 are threadedly engaged. The bottom of the clamping sleeve 12 is pressed against the top of the top fixing ear 8.

[0027] The snap-fit ​​assembly 6, with its hinged design of the first fixing ring 7 and the second fixing ring 71, simplifies and expedites the installation and removal of the mounting post 5. Simultaneously, the mounting base 10, the lead screw 11, and the clamping sleeve 12 in the fixing assembly 9 cooperate with each other, providing a stable fixing force for the mounting post 5 through threaded clamping. Furthermore, the mounting holes on the protruding ears 72 at both ends of the second fixing ring 71 allow for further reinforcement using bolts or other tools, effectively preventing the mounting post 5 from loosening underwater due to water flow impact or the robot's own movement. This ensures the stability of the entire robot structure and provides a solid guarantee for the robot's long-term stable operation underwater.

[0028] The working principle of this utility model:

[0029] When the underwater maintenance robot needs to move, the first propeller 3 and the second propeller 4 are activated. Since the first propeller 3 and the second propeller 4 drive the water flow in different directions, the water flow generates a thrust in the opposite direction on the propellers, thereby enabling the mounting frame 1 and the entire robot to obtain driving forces in different directions underwater, realizing forward, backward, and turning movements.

[0030] When the outer edge of the transparent protective cover 13 needs cleaning, the cleaning motor is started. The cleaning motor drives the hinge seat 16 to rotate back and forth. Since the two ends of the cleaning rod 15 are fixed on the hinge seat 16, the cleaning rod 15 will rotate with the rotation of the hinge seat 16. The cleaning rod 15 has a semi-circular rod structure. The cleaning brush 151 embedded in its inner side will contact the outer edge of the transparent protective cover 13 during the rotation, thereby cleaning away the dirt and impurities attached to the outer edge of the transparent protective cover 13. This avoids the need for the underwater maintenance robot to be hoisted up for cleaning and re-inspection due to dirt during the underwater inspection process, thus improving the overall work efficiency.

[0031] When installing the mounting post 5, open the first fixing ring 7 and the second fixing ring 71 by hinge, place the mounting post 5 in the appropriate position, and then close the first fixing ring 7 and the second fixing ring 71. Then rotate the mounting base 10 so that the lead screw 11 faces the direction to be fixed, and then rotate the clamping sleeve 12. Due to the threaded engagement between the lead screw 11 and the clamping sleeve 12, as the clamping sleeve 12 rotates, it will move downward along the lead screw 11 and finally press against the top of the top fixing ear 8, thereby fixing the mounting post 5. At the same time, the mounting holes on the protruding ears 72 at both ends of the second fixing ring 71 can be used for further reinforcement with bolts or other tools.
