Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel installation, and in particular to photovoltaic power station installation and lifting equipment. Background Art

[0002] The working principle of photovoltaic power plants is based on the photovoltaic effect, which uses photovoltaic panels to convert sunlight into direct current electricity. This electricity is then managed and controlled by a controller and then converted into alternating current by an inverter for use by users or fed into the power grid.

[0003] During the installation of photovoltaic power stations, in order to improve the lighting efficiency, solar photovoltaic panels are mostly laid at higher ground. They need to be lifted to a higher place during installation. In related technologies, workers usually use steel wire ropes to bundle and hoist multiple photovoltaic panels. This method requires bundling and untying back and forth, which is time-consuming and labor-intensive. At the same time, there is a risk of slipping of the steel wire rope, and the safety is relatively low.

[0004] A Chinese patent with authorization announcement number CN118255288B discloses a lifting assembly for photovoltaic panel installation, which includes a base plate, on which a lifting member and a supporting member are installed, the supporting member is installed on the top of the base plate, the lifting member is arranged inside the supporting plate, and the lifting member is connected to the base plate, a protective member for protecting the photovoltaic panel is arranged inside the supporting member, and a blanking member is arranged on one side of the supporting member, and both ends of the blanking member are respectively connected to the supporting member and the base plate.

[0005] The above patent can continuously lift the photovoltaic panels to a high altitude under the action of the lifting parts and the supporting parts, greatly improving the installation efficiency of the photovoltaic panels. However, the patent requires the photovoltaic panels to be placed into the conveyor plate piece by piece, and then taken out piece by piece after being lifted to a high place, which is inefficient. At the same time, due to the heavy weight of the photovoltaic panels themselves, the photovoltaic panels move relative to each other during the process of workers taking in and putting in the photovoltaic panels, which will cause scratches and wear on the surface of the panels. In addition, the device requires a certain amount of space for movement when taking out the panels, which is less flexible. Summary of the invention

There are two first clamping blocks 35, which are respectively arranged at the two ends of the lower beam 33.

Two second clamping blocks 36 are respectively fixedly connected to the two ends of the upper cross beam 34. The second clamping block 36 is elastically connected with a pin 361, and the pin 361 can be received in the second clamping block 36.

[0041] like Figure 2 , Figure 6 and Figure 7As shown, a rotating seat 4 is provided at the end of the push rod 32, and a rotating hole 41 is provided in the rotating seat 4. A fixed groove 42 is provided below the rotating hole 41. A baffle 43 is slidably fitted in the fixed groove 42. The baffle 43 is elastically connected to the rotating seat 4 through a spring. A matching key 331 is fixedly connected to the lower cross beam 33. The matching key 331 extends into the rotating seat 4 and is rotatably fitted with the rotating hole 41. A limiting block 5 is also slidably fitted in the rotating seat 4. The limiting block 5 can move up and down in the rotating seat 4. The limiting block 5 is rotatably connected to the matching key 331 through a torsion spring.

[0042] like Figure 1 and Figure 8 As shown, two symmetrically distributed positioning plates 6 are provided on the frame 1, each positioning plate 6 is elastically connected to the frame 1 through a spring, and a stopper 7 is also provided at the end of the positioning plate 6 away from the frame 1, the stopper 7 is slidably matched with the positioning plate 6, and a lead screw 61 is rotatably connected to the positioning plate 6, the stopper 7 includes a first block 71 and a second block 72, the first block 71 is threadedly matched with the lead screw 61, and the second block 72 is detachably connected to the first block 71, the positioning plate 6 is used to position the photovoltaic panel to prevent the photovoltaic panel from being uneven, and the stopper 7 is used to prevent the photovoltaic panel from tipping over.

[0043] In the related art, a tray 11 is usually used to carry multiple photovoltaic panels. The photovoltaic power station installation and lifting equipment of the embodiment of the present invention is suitable for placing photovoltaic panels vertically on the tray 11. First, remove the second block 72, and then transport the tray 11 carrying the photovoltaic panels to the support table 8. By rotating the roller 10, the tray 11 is gradually approached to the clamping mechanism 3, and then the second block 72 is installed. The stopper 7 can stop against the outermost photovoltaic panel, and the positioning plate 6 can clamp the upper part of the photovoltaic panel to prevent the photovoltaic panel from tipping over. Fig. 9 and Fig.10As shown, in the initial state, the bottom surface of the lower beam 33 is flush with the upper surface of the pallet 11, the scissor lift mechanism 37 is in a retracted state, and the upper beam 34 is close to the lower beam 33. At this time, the driving member 9 drives the support platform 8 to tilt, so that the end of the support platform 8 close to the clamping mechanism 3 moves downward. At this time, since the upper part of the photovoltaic panel is clamped by the positioning plate 6, the photovoltaic panel is stationary when the end of the support platform 8 close to the clamping mechanism 3 is downward, and a gap is formed between the innermost photovoltaic panel and the pallet 11. At the same time, the push rod 32 pushes the clamping mechanism 3 to move toward the photovoltaic panel. During the movement of the clamping mechanism 3, the base 351 and the support plate 332 will be inserted between the photovoltaic panel and the pallet 11, so that the photovoltaic panel can pass over the movable roller 353 and be placed on the conveyor belt 356. The roller 358 moves along the pallet 11, thereby rotating and driving the driving roller 357 to rotate. The driving roller 357 drives the conveyor belt 356 to rotate, so that the photovoltaic panel The bottom plate and the clamping plate 352 are stopped. During this process, the conveyor belt 356 drives the bottom of the photovoltaic panel to move close to the clamping plate 352, so that a gap is generated in the lower area between the two innermost photovoltaic panels. At the same time, the block 7 pushes the photovoltaic panel close to the clamping mechanism 3, so that the innermost photovoltaic panel is out of contact with the positioning plate 6. The conveyor belt 356 drives the movable roller 353 to rotate. The photovoltaic panel applies downward pressure to the lever 355 under the action of its own gravity, so that the movable roller 353 can rotate around the rotating shaft 354, and the movable roller 353 is lifted up. The movable roller 353 applies pressure to the photovoltaic panel, so that the photovoltaic panel is tightly attached to the clamping plate 352. Since the photovoltaic panel is placed on the conveyor belt 356, when the movable roller 353 is lifted up, the photovoltaic panel applies downward pressure to the conveyor belt 356, thereby squeezing the conveyor belt 356, ensuring that the conveyor belt 356 is always frictionally matched with the driving roller 357 and the movable roller 353.During the movement of the clamping mechanism 3, the pin 361 on the second clamping block 36 will pass over the photovoltaic panel and gradually move into the gap between the lower areas of the two photovoltaic panels. At this time, the hydraulic cylinder drives the slider 374 to move upward, so that the scissor lift mechanism 37 is extended, the upper beam 34 moves upward, and drives the second clamping block 36 to move upward. The second clamping block 36 gradually moves to the top of the photovoltaic panel, thereby clamping the top of the photovoltaic panel. During this process, the second clamping block 36 pushes the upper end of the photovoltaic panel close to the upper beam 34, and finally makes the photovoltaic panel vertically distributed. The two first clamping blocks 35 and the two second clamping blocks 36 respectively clamp the four corners of the photovoltaic panel, so that the photovoltaic panel can be fixed on the clamping mechanism 3. The mating key 331 is located in the fixing groove 42 and is engaged with the fixing groove 42. The baffle 43 is located at the bottom end of the fixing groove 42. The spring is in a contracted state. The winch is started to transport the clamping mechanism 3 upward. When the clamping mechanism 3 is transported to the top, the staff can pull the photovoltaic panel out of the clamping mechanism 3. During the extraction process, the photovoltaic panel can be lifted upward first. The spring releases the elastic force, so that the baffle 43 pushes the mating key 331 into the rotating hole 41. The mating key 331 can rotate in the rotating hole 41, so that the lower beam 33 can rotate, so that the photovoltaic panel can be tilted and pulled out to achieve the lifting of a single photovoltaic panel. Then the winch transports the clamping mechanism 3 downward and starts the lifting process of the next photovoltaic panel.
