[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an underwater search and rescue robot, which has the following beneficial effects:

[0018] 1. Driven by the second waterproof motor, the fixed base rotates, thereby driving the cleaning brush to rotate, which in turn makes the cleaning brush contact the front and rear curved transparent covers. Then, driven by the first waterproof motor, the connecting rod rotates, which in turn drives the connecting base, the second waterproof motor, and the fixed base to rotate, thereby driving the cleaning brush to rotate, thus cleaning the front and rear curved transparent covers.

[0019] 2. Driven by the second waterproof motor, the fixed base rotates, thereby driving the connecting shaft and the crushing blade to rotate, which in turn causes the crushing blade to contact the front arc-shaped transparent cover and the rear arc-shaped transparent cover. Then, driven by the third waterproof motor, the connecting shaft rotates, thereby driving the crushing blade to rotate in and out, thereby cleaning the entangled material.

[0020] 3. The universal ball rolling on the concave ring supports the rotation of the connecting rod, thereby supporting the cleaning of the front and rear arc-shaped transparent covers and improving the stability of the cleaning process.

[0021] 4. Driven by the waterproof electric push rod, the fourth waterproof motor moves, extending the shredding blade. Then, driven by the fourth waterproof motor, the shredding blade rotates, breaking up the aquatic plants in the water so that the robot body can pass through quickly and easily.

[0031] Reference Figures 1-5 An underwater search and rescue robot includes a robot body 1. Search components 2 are bolted to multiple sides of the robot body 1. A front arc-shaped transparent cover 3 is bolted to one end of the robot body 1, and a rear arc-shaped transparent cover 4 is bolted to the other end. The front and rear arc-shaped transparent covers 3 and 4 cover the search components 2, providing protection. Two first waterproof motors 5 are bolted to the top of the robot body 1. A connecting rod 6 is fixedly fitted to the output end of each first waterproof motor 5. The other end of the connecting rod 6 is connected to a seat 7. A second waterproof motor 8 is bolted to one side of the connecting seat 7. A fixing seat 9 is bolted to the output end of the second waterproof motor 8. A fixing rod 10 is bolted to the top of the fixing seat 9. A cleaning brush 11 is attached to one side of the fixing rod 10. Driven by the second waterproof motors 8, the fixing seat 9 rotates, thereby driving... The cleaning brush 11 rotates, causing it to contact the front arc-shaped transparent cover 3 and the rear arc-shaped transparent cover 4. Then, driven by the first waterproof motor 5, the connecting rod 6 rotates, thereby causing the connecting seat 7, the second waterproof motor 8, and the fixing seat 9 to rotate, which in turn causes the cleaning brush 11 to rotate, thus cleaning the front arc-shaped transparent cover 3 and the rear arc-shaped transparent cover 4. The bottom of the fixing seat 9 is fixed with a third waterproof motor 12 by bolts. The output end of the third waterproof motor 12 is fixed with a connecting shaft 13 by bolts. Multiple short breaking blades 14 are welded to the outer wall of the connecting shaft 13. Driven by the second waterproof motor 8, the fixing seat 9 rotates, thereby causing the connecting shaft 13 and the short breaking blades 14 to rotate, thus causing the short breaking blades 14 to contact the front arc-shaped transparent cover 3 and the rear arc-shaped transparent cover 4. Then, driven by the third waterproof motor 12, the connecting shaft 13 rotates, thereby causing the short breaking blades 14 to rotate in and out, thus cleaning the entangled material.

[0032] The search component 2 includes a mounting base 201, which is bolted to the robot body 1. Multiple cameras 202 and multiple lights 203 are bolted to one side of the mounting base 201. A fixed limit block 16 is bolted to one side of the connecting base 7, and a movable limit block 15 is bolted to one side of the fixed base 9. The movable limit block 15 contacts the fixed limit block 16, thereby limiting the rotation of the fixed base 9. A connecting rib 17 is welded between the connecting rod 6 and the connecting base 7 to enhance the connection between them. A universal ball 18 is rotatably connected to one side of the connecting base 7. The top of the robot body 1 is open... Two concave rings 19 are fixed by bolts, and the universal ball 18 rolls on the concave rings 19 to support the rotation of the connecting rod 6, thereby supporting the cleaning of the front arc transparent cover 3 and the rear arc transparent cover 4 and improving the cleaning stability. The top of the robot body 1 is fixed with an ultrasonic sensor 20 by bolts. Search and rescue work is carried out by using the camera 202, the lighting lamp 203 and the ultrasonic sensor 20. The bottom of the robot body 1 is fixed with two base plates 21 by bolts. The bottom of the base plates 21 is fixed with two ball-head hollow seats 22 by bolts, which support the robot body 1.

[0033] The working principle of this embodiment is as follows: In use, firstly, search and rescue operations are conducted using the camera 202, lighting 203, and ultrasonic sensor 20. Then, the search component 2 is protected by the front curved transparent cover 3 and the rear curved transparent cover 4. When cleaning of the outer surfaces of the front curved transparent cover 3 and the rear curved transparent cover 4 is required, the fixed base 9 rotates under the drive of the second waterproof motor 8, thereby driving the cleaning brush 11 to rotate, causing the cleaning brush 11 to contact the front curved transparent cover 3 and the rear curved transparent cover 4. Then, the connecting rod 6 rotates under the drive of the first waterproof motor 5, thereby driving the connecting base 7... The second waterproof motor 8 and the fixed base 9 rotate, which in turn drives the cleaning brush 11 to rotate, thus cleaning the front arc-shaped transparent cover 3 and the rear arc-shaped transparent cover 4. When it is necessary to clean the entangled material on the front arc-shaped transparent cover 3 and the rear arc-shaped transparent cover 4, the fixed base 9 rotates under the drive of the second waterproof motor 8, which in turn drives the connecting shaft 13 and the crushing blade 14 to rotate, so that the crushing blade 14 contacts the front arc-shaped transparent cover 3 and the rear arc-shaped transparent cover 4. Then, the connecting shaft 13 rotates under the drive of the third waterproof motor 12, which drives the crushing blade 14 to rotate in and out, thereby cleaning the entangled material.

A shredding blade 26 is fixed to the output end of the fourth waterproof motor 25 by bolts. Driven by the waterproof electric push rod 24, the fourth waterproof motor 25 moves, thereby extending the shredding blade 26. Then, driven by the fourth waterproof motor 25, the shredding blade 26 rotates, thereby shredding aquatic plants in the water to allow the robot body 1 to pass.

[0036] The working principle of this embodiment is as follows: When in use, firstly, the fourth waterproof motor 25 moves under the drive of the waterproof electric push rod 24, thereby extending the breaking blade 26. Then, the breaking blade 26 rotates under the drive of the fourth waterproof motor 25, thereby breaking the aquatic plants in the water so that the robot body 1 can pass through.
