For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figure 1-4 As shown, the present invention proposes a hybrid power supply underwater inspection robot for offshore wind power projects, comprising a device body 1, a power supply 4, a support plate 5, two telescopic devices 6, two second fixed plates 7, a sealing ring plate 8, two connecting plates 9, two sliding plates 10, an insulating plate 13, and a backup power supply 20.

[0031] The device body 1 is a hollow cuboid frame structure. The four side walls of the device body 1 are divided into a first side wall 103 and a third side wall 105, which are arranged opposite each other, and a second side wall 104 and a fourth side wall 106, which are arranged opposite each other. The outer peripheral surfaces of the four side walls bulge outward to form arc surfaces. The arc surfaces reduce the resistance of water flow to the device body 1, making it easier to adjust the device and stabilize the robot's posture. The device body 1 is provided with a through groove 101, which passes through the first side wall 103 and the third side wall 105. The lower part of the first side wall 103 and the third side wall 105 are respectively connected to the track structure 11. The second side wall 104 and the fourth side wall 106 are provided with multiple second through holes 102. The second through holes 102 on the two opposite side walls are arranged in the same position and number. By setting multiple opposite second through holes 102, water flow can pass through the inside of the robot to cool the power supply 4 and the backup power supply 20 inside the device body 1, thereby reducing the robot's water resistance. The second sidewall 104 and the fourth sidewall 106 are provided with pushers 12. The upper end face of the device body 1 is provided with a limit component 2. The limit component 2 includes bolts and pressure blocks for pressing the power supply 4. The power supply 4 and the backup power supply 20 are both located in the through groove 101. The power supply 4 and the backup power supply 20 respectively press the two ends of the sealing return plate 8. The end faces of the power supply 4 and the backup power supply 20 that are close to each other are provided with batteries.

[0032] See Figure 2 and Figure 5 A sealing ring plate 8 is provided between the power supply 4 and the backup power supply 20. The upper and lower ends of the sealing ring plate 8 are open, and the sealing ring plate 8 is a ring structure with a square cross-section. On the two opposite outer walls of the sealing ring plate 8, there is an inwardly recessed groove 801. The two grooves 801 are opposite to the inner surfaces of the second side wall 104 and the fourth side wall 106, respectively. A connecting plate 9 is installed on the second side wall 104 and the fourth side wall 106. The two connecting plates 9 are installed side by side in the through groove 101 and are at the same height in the through groove 101. A sliding plate 10 is fixedly connected to the end face of the two connecting plates 9 that are close to each other. The two sliding plates 10 are slidably connected to the inner walls of the two grooves 801, and can slide up and down in their respective grooves 801. The two grooves 801 limit the movement of the two sliding plates 10, which facilitates the installation and removal of the power supply 4 and the backup power supply 20.

[0033] Both the power supply 4 and the backup power supply 20 have mating grooves on their adjacent end faces; the two ends of the sealing molded plate 8 press against the inner walls of the two mating grooves respectively; each mating groove has a rubber gasket on its inner wall, which seals the groove and prevents water from entering the sealing molded plate 8; the inner wall of the through groove 101 has a groove; the pressure block slides to connect to the inner wall of the groove; the bolt spirals through the device body 1 and connects to the pressure block; in the installed state, the pressure block presses against the power supply 4.

[0034] like Figure 5 As shown, it also includes two first fixing plates 18 and two sets of springs 19; the two first fixing plates 18 are respectively connected to the two opposite ends of the sealing molded plate 8, and the two first fixing plates 18 are respectively located directly below the two sliding plates 10; the two ends of each set of springs 19 are respectively connected to the first fixing plate 18 and the sliding plate 10. When the limiting component 2 presses the power supply 4, the power supply 4, the sealing molded plate 8 and the backup power supply 20 are in a sealed state, and the two sets of springs 19 are in a compressed state; when the power supply 4 and the backup power supply are removed or installed, the two sets of springs 19 push the two sliding plates 10, so that the sealing molded plate 8 is slidably connected to the two sliding plates 10, which facilitates the adjustment of the position of the sealing molded plate 8; when the bolts and pressure blocks are separated from the power supply 4, it is easy to adjust the position of the sealing molded plate 8, which improves the practicality of the device.

[0035] An annular support plate 5 is provided inside the sealing ring plate 8. The support plate 5 has a first through hole 501. An insulating plate 13 is fixedly installed on the support plate 5. Opposite conductive blocks 14 are provided inside the sealing ring plate 8, with the conductive blocks 14 on both sides of the support plate 5. Each conductive block 14 has a conductive ring 141 on its outer end face for connecting to the connecting pipe 3. The inner ends of the two conductive blocks 14 are respectively connected to the two sides of the insulating plate 13, and the outer ends are connected to the connecting pipe 3. Two second fixing plates 7 are fixedly installed inside the sealing ring plate 8, set on two opposite side walls of the sealing ring plate 8. The fixed ends of the two telescopic devices 6 are respectively connected to the lower ends of the two second fixing plates 7, and the telescopic ends of the two telescopic devices 6 are connected to the support plate 5.

[0036] Power supply 4 and backup power supply 20 are each equipped with a battery remaining power detection device 16. The two telescopic devices 6 and the two battery remaining power detection devices 16 are all connected to the controller circuit. The controller is located inside the sealed U-shaped plate 8.

[0037] The upper end face of the backup power supply 20 is provided with two conductive connectors 17, and the lower end face of the power supply 4 is provided with two conductive connectors 17. All conductive connectors 17 are U-shaped blocks, and the width of the groove in the U-shaped structure matches the width of the conductive block 14. When the conductive block 14 moves downward, the conductive block 14 is inserted into its corresponding conductive connector 17 below it, and the conductive block 14 can be connected to the backup power supply 20. When the conductive block 14 moves upward, the conductive block 14 is inserted into its corresponding conductive connector 17 above it, and the conductive block 14 is connected to the power supply 4.

[0038] The connecting pipe 3 has a bent structure. The upper end of the vertical section is connected to the robot, and the outer end of the horizontal section passes through the sealing ring plate 8 and the conductive block 14. The connecting pipe 3 passes through the limiting ring on the sealing ring plate 8 to fix and limit the connecting pipe 3, which helps to extend the service life of the connecting pipe 3. A corrugated pipe is provided at the connection between the connecting pipe 3 and the sealing ring plate 8. A conductive ring 141 is provided at the connection between the connecting pipe 3 and the conductive block 14. The conductive ring 141 is semi-circular, passes through the connecting pipe 3, and is connected to the conductive block 14 at both ends.

[0039] Working principle: When using this robot, the user places the power supply 4 and the backup power supply 20 in the through slot 101, rotates the bolts to press the pressure block onto the power supply 4, and the power supply 4 presses the sealing ring plate 8 onto the backup power supply 20, thus fixing the power supply 4 and the backup power supply 20. The battery remaining power detection device 16 detects and displays the remaining power of the power supply 4 and the backup power supply 20. The controller controls the telescopic device 6 to start, driving the support plate 5 and the insulating plate 13 to move up and down, so that the conductive block 14 alternately contacts and presses against the conductive connector 17 on the power supply 4 and the backup power supply 20. When the telescopic device 6 extends, the conductive block 14 does not contact the power supply 4 and the backup power supply 20, avoiding the power supply 4 and the backup power supply 20 from running out of power, which would reduce the life of the power supply 4 and the backup power supply 20, thus protecting the power supply 4 and the backup power supply 20. At the same time, the power supply 4 and the backup power supply 20 ensure the long-term operation of the device, improving the practicality of the device.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
