Description
Technical Field
[0001] This invention relates to the field of power transmission line inspection technology, specifically a lightweight inspection robot for power transmission lines. Background Technology
[0002] Power transmission lines require regular inspections by staff during routine operations. With advancements in technology, many places now utilize robots for these inspections, significantly reducing workload and increasing efficiency. A patent (CN201510949895.8) exists that uses a robot in conjunction with lightning protection wires to reduce construction costs. Furthermore, the robot's electrical equipment draws power from the energized rail via carbon brushes, eliminating the need for a dedicated power supply system and making the robot lighter. However, it still has some drawbacks: firstly, the robot lacks protective devices, making it vulnerable to damage from rain; secondly, its power supply is not clean enough. Summary of the Invention

In addition, the first protective cover 4 is located on one side of the inspection robot 1 when not in operation.
[0027] The second protective cover 5 is installed on the inspection robot 1 on the opposite side of the first protective cover 4. The upper top surface of the second protective cover 5 is also symmetrically provided with insertion through holes on both sides. A sealing ring block 51 is fixedly provided on the front end surface of the second protective cover 5. The sealing ring block 51 is inserted into the sealing groove 41 in the working state. Support blocks 52 are symmetrically welded on both sides of the upper end of the second protective cover 5. The support blocks 52 are provided with second connection holes 53. The inner sides of the second protective cover 5 are symmetrically fixed with mating sliders 54. The mating sliders 54 are inserted into the mating grooves 15. In the non-working state, the second protective cover 5 is on the other side of the inspection robot 1. In the working state, the two protective covers are closed together to protect the inspection robot 1.
[0028] The lower end of the movable hinge frame 6 is welded with a connecting rod 61, and two movable hinge frames 6 are installed on the support mounting rod 43. The connecting rod 61 is inserted into the first connecting hole 44, and the movable hinge frame 6 is located at the upper end of the support mounting rod 43. A connecting spring 7 is sleeved on the connecting rod 61, and a screw is threaded to its lower end. The other two movable hinge frames 6 are installed at the support block 52, and the connecting rod 61 is inserted into the second connecting hole 53. The movable hinge frames 6 installed at the support block 52 are located at the lower end of the support block 52. The connecting spring 7 installed on the support mounting rod 43 is located at the lower end of the support mounting rod 43, and its two ends are in contact with the lower end face of the support mounting rod 43 and the nut on the screw, respectively. The connecting spring 7 installed at the support block 52 is located at the upper end of the support block 52, and its two ends are in contact with the upper end face of the support block 52 and the nut on the screw, respectively.
[0029] The rotating ring 8 is sleeved on the hinge post 13, and a short shaft 81 is fixedly provided at the lower end of the rotating ring 8. The lower end of the short shaft 81 is hinged to the movable hinge frame 6 on the support mounting rod 43. In addition, a long shaft 82 is fixedly provided at the upper end of the rotating ring 8. The upper end of the long shaft 82 is hinged to the movable hinge frame 6 installed on the support block 52. The rotating ring 8 is in a vertical state when not in operation, and the long shaft 82 is located above the short shaft 81.
[0030] The first protective cover 4 and the second protective cover 5 are equipped with a convenient cleaning mechanism for cleaning the solar panel 3. The convenient cleaning mechanism includes four movable plug rods 9, two of which are inserted into the plug-in through holes on the first protective cover 4 and the other two are inserted into the plug-in through holes on the second protective cover 5. In addition, a mating cylindrical block 91 is fixedly provided at the lower end of the movable plug rod 9, and a mating cylinder 92 is fixedly provided on the outer side of the mating cylindrical block 91. The mating cylinder 92 is inserted into the Z-shaped slide groove 17. The mating cylindrical block 91 has a shaft hole, and the connecting shaft 93 is inserted into the shaft hole. The sponge block 94 is sleeved on the connecting shaft 93. The sponge block 94 is in a cylindrical state. In the initial state, it is located at the upper end of the solar panel 3. The diameter of the mating sleeve 92 is equal to the width of the Z-shaped slide groove 17. The shaft hole passes through the mating cylinder 92. In the working state, the sponge block 94 contacts the solar panel 3 and forms a certain amount of compression.
[0031] When it rains, the electric telescopic rod 2 is activated, moving the first protective cover 4 closer to the inspection robot 1. This, in turn, causes the rotating ring 8 to rotate under the action of the movable hinge frame 6, pulling the second protective cover 5 closer to the inspection robot 1. The two protective covers then move towards each other, eventually closing together to cover the inspection robot 1 and protect it. When closed, the sealing ring block 51 is inserted into the sealing groove 41, ensuring a tight seal at the connection point. Furthermore, during the movement of the first and second protective covers 4 and 5 towards each other, the Z-shaped sliding groove 17 on the Z-shaped frame 16 causes the sponge block 94 to move closer to the solar panel 3, creating a certain amount of pressure between it and the solar panel 3. This movement of the first and second protective covers 4 and 5 moves the sponge block 94, allowing it to wipe the solar panel 3, removing not only rainwater but also dust, ensuring the safe use of the solar panel 3.
