[0002] Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight into electrical energy. Whether it is used independently or connected to the grid, the photovoltaic power generation system is mainly composed of three parts: solar panels (modules), controllers and inverters. They are mainly composed of electronic components and do not involve mechanical parts. Therefore, photovoltaic power generation equipment is extremely refined, reliable, stable, long-life, and easy to install and maintain. In theory, photovoltaic power generation technology can be used in any occasion where power is needed, from spacecraft to household power, from megawatt-level power stations to toys. Photovoltaic power is everywhere. The efficiency of domestic crystalline silicon cells is about 10 to 13%, and the efficiency of similar foreign products is about 12 to 14%. A solar panel composed of one or more solar cells is called a photovoltaic module.

[0003] The grid-connected photovoltaic power generation system is a system that directly connects the DC power generated by solar panels to the public power grid after being converted into AC power that meets the requirements of the municipal power grid by a grid-connected inverter. The main feature is that the generated energy is directly transmitted to the power grid, which is then uniformly allocated by the power grid to supply power to users. In the existing technology, the photovoltaic power generation system needs to be connected to the public power grid through cables to achieve power transmission.

[0004] At present, in the process of laying transmission lines, when laying cables on transmission towers, one end of a steel wire or rope is often first connected to the cable through a connecting device, and then the other end of the traction steel wire or traction rope is passed through a pulley temporarily installed under the transmission tower and dragged.

The power input rod 260 is located on both sides of the base 210 and is rotatably connected to the base 210. When the power input rod 260 rotates, it drives the active bevel gear 250 to rotate, and the active bevel gear 250 rotates. When the driven bevel gear 240 is rotated, the driven bevel gear 240 is driven to rotate. When the driven bevel gear 240 rotates, the lead screw 230 is driven to rotate. Since the lead screw 230 is threadedly connected to the moving platform 310, the moving assembly 300 is driven to move. When the moving platform 310 is fixed to the cable, the cable is dragged. When it is necessary to drive the moving assembly 300 to reset, the limit block 164 is first inserted into the gap of the limit wheel 165 through the movable rod 162 to prevent the first guide wheel 120 from rotating. Then, the first clamping block 150 is moved downward by rotating the adjusting rod 140. When the first clamping block 150 clamps the cable, the moving assembly 300 is separated from the cable. Then, the power input rod 260 is rotated in the opposite direction to reset the moving assembly 300.

[0035] The moving assembly 300 is used to drive the cable to move through the driving assembly 200, the moving platform 310 is used to carry the second guide wheel 320, the second guide wheel 320 is used to facilitate movement when resetting, the slot 321 is used to cooperate with the latch tooth 351 to limit the second guide wheel 320, the mounting plate 330 is used to carry the locking rod 340, the locking rod 340 is used to drive the second clamping block 350 to move, and to fix and detach the passing cable, the second clamping block 350 is used to cooperate with the second guide wheel 320 to fix the cable, and the latch tooth 351 is installed. When the second clamping block 350 moves downward, the latch tooth 351 installed at its bottom is inserted into the slot 321 opened on the second guide wheel 320, so that it limits the second guide wheel 320, increases the effect of the second clamping block 350 on fixing the cable, and the bearing slot 360 is used to carry the clutch assembly 400.

[0036] Through the driving assembly 200 and the moving assembly 300, the cables on the mounting frame 100 can be dragged to facilitate the movement of the cables. The passing cables can be fixed through the moving assembly 300, and then the active bevel gear 250 can be driven to rotate through the power input rod 260. When the active bevel gear 250 rotates, it drives the driven bevel gear 240 to rotate. When the driven bevel gear 240 rotates, it drives the screw rod 230 to rotate. When the screw rod 230 rotates, it drives the moving assembly 300 to move. When the moving assembly 300 moves, it drives the cables to move.

[0037] The buffer assembly 500 is used to reduce the shaking of the cable when the cable shakes under strong wind conditions, thereby increasing the installation efficiency of the cable.

In cooperation with the buffer rod 560 at the bottom, the shaking of the supporting frame 530 can be reduced when the output line of the supporting frame 530 shakes up and down. The supporting frame 530 is used to support the third guide wheel 540. The third guide wheel 540 is used to reduce the friction between the cable and the supporting frame 530 and transmit the shaking of the cable to the supporting frame 530. The adapter platform 550 is used to rotatably connect the supporting frame 530 and the buffer rod 560. The buffer rod 560 is used to absorb the pressure on the supporting frame 530, thereby reducing the frequency and number of shaking of the supporting frame 530 when the cable shakes.

[0039] Figure 7-10 FIG. 1 is a schematic diagram showing a second embodiment of a photovoltaic power transmission cable installation device according to the present invention. Figure 7-10 , which is different from the above-mentioned embodiment, since in the above-mentioned first real-time method, the screw rod 230 is driven to reverse when the power input rod 260 reverses, thereby resetting the moving component 300, this resetting method is less efficient and affects the installation efficiency of the transmission cable.

[0040] The clutch assembly 400 is used to improve the resetting efficiency of the moving assembly 300. A bearing groove 360 ​​is provided at the bottom of the moving platform 310, and the clutch assembly 400 is installed in the bearing groove 360. The clutch assembly 400 includes two threaded blocks 410. Rotating shafts 420 are installed on the outer walls of both sides of the two threaded blocks 410.

There are two screw rods 440, and the two screw rods 440 are rotatably connected by a connecting shaft 450 in the middle. The connecting shaft 450 is slidably connected to the two screw rods 440.

[0041] The thread block 410 is used to be threadedly connected with the screw rod 230, replacing the movable platform 310 to be threadedly connected with the screw rod 230. The rotating shaft 420 is used to carry the thread block 410 to be rotatably connected with the movable platform 310. The adapter block 430 connects the screw rod 440 and the thread block 410. The screw rod 440 is used to be threadedly connected with the movable platform 310. When the adapter block 430 rotates, the thread block 410 is driven to rotate. The two screw rods 440 rotate in the same direction and move in opposite directions, so that the thread block 410 and the screw rod 230 can be connected. The rod 230 is screwed and separated. When the threaded block 410 is separated from the screw rod 230, the moving assembly 300 is pushed to quickly reset. When the threaded block 410 is screwed to the screw rod 230, the driving assembly 200 drives the moving assembly 300 to move. The connecting shaft 450 is used to connect the two screw rods 440, so that the screw rod 440 on one side can be rotated to drive the screw rod 440 on the other side to rotate at the same time. The sleeve 460 is used to facilitate the connection with a hexagonal wrench or a hand drill.

[0042] The clutch assembly 400 installed in the bearing groove 360 ​​can increase the efficiency of resetting the moving assembly 300. When the screw rod 440 rotates, the screw rod 440 drives the adapter block 430 to move. When the adapter block 430 moves, it drives the threaded block 410 to rotate. When the two threaded blocks 410 are screwed with the screw rod 230, the moving assembly 300 can be driven to move by the driving assembly 200. When the threaded block 410 is separated from the screw rod 230, the moving assembly 300 can slide on the base 210 to achieve rapid resetting of the moving assembly 300.
