Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic modules, and in particular to a photovoltaic module hoisting device. Background Art

[0002] Photovoltaic modules, also known as solar cell modules, are the core components of solar power generation systems and are responsible for converting the received solar energy into electrical energy. Photovoltaic modules consist of multiple photovoltaic panels, which are connected in series and parallel to convert light energy into direct current for use by the entire system.

[0003] Photovoltaic modules are generally installed in open areas such as rooftops with good lighting. When installing photovoltaic modules, they need to be lifted from the ground to the roof. Before lifting the photovoltaic modules, the staff first unpacks the photovoltaic modules and removes the outer facade of the photovoltaic module packaging, leaving only the tray and the photovoltaic module buckles.

[0004] Then use a crane to lift the photovoltaic components as a whole. During lifting, pass the crane's sling through the pallet, tie and fix the photovoltaic components from bottom to top, and then start the crane. The crane lifts the photovoltaic components to the required position to realize the lifting of the photovoltaic components.

[0005] With regard to the above-mentioned related technologies, the binding slings are in direct contact with the photovoltaic modules. During the lifting process, the binding slings are easy to squeeze the photovoltaic modules, causing the photovoltaic modules to deform and break, posing a great safety hazard. Utility Model Content

[0006] In order to prevent the binding straps from squeezing the photovoltaic modules, the present application provides a photovoltaic module lifting device.

[0007] The photovoltaic module hoisting device provided in this application adopts the following technical solution:

[0008] A photovoltaic module hoisting device comprises a mounting frame; the mounting frame comprises an upper support frame, a lower support frame and a plurality of side support columns; the plurality of side support columns are located between the upper support frame and the lower support frame, and the plurality of side support columns are axially arranged in parallel, one end of the side support column is connected to the upper support frame, and the other end is connected to the lower support frame; a placement cavity is formed between the upper support frame, the lower support frame and the plurality of side support columns, and the placement cavity is used to place photovoltaic modules.

[0009] By adopting the above technical scheme, the staff first unpacks the photovoltaic components and removes the outer facade of the photovoltaic component packaging, leaving only the clips between the pallet and the photovoltaic component. The staff uses a forklift to transport the photovoltaic components to the placement cavity, and then passes the two slings of the crane through the bottom of the pallet to tie and fix the photovoltaic components from bottom to top, and starts the crane. The crane hoisting installation frame and the photovoltaic component move synchronously. When the photovoltaic component is hoisted above the roof and falls to about 10 cm from the roof, the crane stops descending, and the photovoltaic component is suspended above the roof. Then three staff members form a group to extract the panels of the photovoltaic components. When extracting the panels, one staff member pulls forward, one staff member pushes backward, and one staff member holds the installation frame. With the cooperation of the three staff members, all photovoltaic panels are extracted in turn, and finally the photovoltaic components are disassembled. The photovoltaic component hoisting device is set up, by placing the photovoltaic component in the installation frame, so that the crane slings and the photovoltaic components are not in direct contact, avoiding the damage of the photovoltaic components caused by the slings squeezing the photovoltaic components during the hoisting process, thereby improving the safety of the photovoltaic component hoisting process.

[0010] In a specific feasible implementation scheme, the side support column includes an upper support rod, a lower support rod and a locking piece; the lower support rod is installed on the lower support frame, and the radial direction of the lower support rod is parallel to the plane where the lower support frame is located, and the upper support rod is coaxially sleeved on the end of the lower support rod away from the lower support frame; the locking piece is installed on the lower support rod, and is used to fix the upper support rod to the lower support rod.

At this time, the upper support rod can slide along the length direction of the lower support rod. The staff adjusts the position of the upper support rod to the required position and loosens the pulling plate to make the locking screw automatically insert into the height adjustment hole, thereby fixing the position of the upper support rod. The locking piece is arranged, through the locking screw, compression spring and pulling plate, so that the locking screw can be inserted into the height adjustment hole after the staff stops applying force to the locking screw, thereby improving the adjustment efficiency of the photovoltaic module lifting device.

[0014] In a specific feasible implementation scheme, the side support column also includes two groups of adjusting parts for adjusting the position of the locking part, the two groups of adjusting parts are symmetrically distributed at both ends of the locking screw, and the lower support rod is provided with a sliding groove for the sliding of the two groups of adjusting parts, and the adjusting part includes a sliding rod and a sliding block; the sliding block is installed in the sliding groove, one end of the sliding rod is connected to one end of the pulling plate, and the other end is connected to the end of the sliding block away from the sliding groove.

[0015] By adopting the above technical solution, the staff applies force to the pulling plate, and the pulling plate drives the sliding rod and the sliding block to move synchronously until the sliding rod is in a horizontal state. At this time, the locking screw is disengaged from the height adjustment hole, and the staff stops applying force to the pulling plate, and the positions of the pulling plate, sliding rod, sliding block and locking screw are fixed, so that the locking screw is stably disengaged from the height adjustment hole; the arranged adjustment piece, through the sliding rod and the sliding block, makes the locking screw stably disengaged from the height adjustment hole, thereby preventing the staff from applying force to the pulling plate all the time, thereby improving the convenience of height adjustment of the photovoltaic module lifting device.

The fixing parts are installed on the flexible parts and are used to fix the flexible parts on the side support columns.

[0021] By adopting the above technical solution, the protective component is set up, and the flexible part is used as an additional protective layer to avoid direct contact between the photovoltaic component and the side support column, thereby further improving the safety of the photovoltaic component hoisting process.
