Background Art

[0002] With the continuous advancement of photovoltaic technology, the role and impact of flexible photovoltaic brackets as an important part of photovoltaic systems are increasingly valued by the industry. Flexible photovoltaic brackets are gradually occupying a larger share in the development of the industry due to their high comprehensive land utilization rate, low construction cost and fast construction.

[0003] Flexible photovoltaic brackets use steel cables to replace traditional purlin structures, which has the characteristics of saving material consumption. However, traditional flexible photovoltaic brackets install photovoltaic modules on steel cables, which requires the photovoltaic modules to be transported to the steel cables, and then the installation workers fix the photovoltaic modules on the steel cables. The transportation and installation of photovoltaic modules are very inconvenient. Especially when flexible photovoltaic brackets are installed in mountainous areas with complex terrain or above open ponds, because it is difficult for construction machinery such as transport vehicles, cranes, and aerial vehicles to reach the installation site, photovoltaic modules can only be transported by manpower, and their transportation efficiency is very low; during installation, workers need to climb to install modules on steel cables, which is highly dangerous and has low installation efficiency. Traditional installation technology makes it impossible to implement flexible photovoltaic brackets in areas such as steep and complex terrain mountains or open and difficult-to-cross ponds due to the difficulty of construction and high cost.

[0011] The component cable installation assembly comprises a component cable anchoring assembly and a component cable positioning assembly connected to the middle cross beam or to a structure fixed to the middle cross beam.

[0012] On the basis of adopting the above technical solutions, the present invention may also adopt the following further technical solutions, or use these further technical solutions in combination:

[0013] The front end cross beam and the rear end cross beam are respectively provided with holes, and the traction rope passes through the holes. The front end cross beam and the rear end cross beam also serve as anchoring support structures, and the anchoring assembly is fixed at the front end of the hole on the front end cross beam and the rear end of the hole on the rear end cross beam respectively.

[0014] The lower end mating portion is located on the pre-installed portion.

[0015] Each photovoltaic module has two module cables and two sets of guide rail modules corresponding to the two module cables one by one; the pre-installation part is provided with a photovoltaic module support structure matching with the module cables, the photovoltaic module support structure is provided with a groove matching with the module cables, the photovoltaic module support structure is connected with the photovoltaic module, the on-site installation part includes a locking structure connected with the photovoltaic module or the photovoltaic module support structure, and the lower end of the locking structure is provided as the lower end matching part.

[0016] The guide rail assembly includes a guide rail type connection assembly located at both ends; the guide rail type connection assembly includes a T-shaped connection member and the locking structure matching the T-shaped connection member; the T-shaped connection member is used for the photovoltaic component support structure, and the bottom of the vertical plate of the T-shaped connection member is provided with the groove matching the component cable; the locking structure includes a groove structure and connection parts located on both sides of the groove notch, the connection parts are connected to the photovoltaic component or the structure fixedly connected to the photovoltaic component, the vertical plate of the T-shaped connection member is wrapped by the groove structure, the component cable is located between the bottom of the vertical plate of the T-shaped connection member and the bottom of the groove structure and is clamped, and the outer side of the groove structure is the lower end matching part matching with the pulley groove.

[0017] The longitudinal beams are connected between the T-shaped connecting members in the guide rail type connecting assemblies at both ends.

[0018] According to the second aspect of the present invention, the present invention adopts the following technical solution:

[0019] The photovoltaic module traction installation method based on the above-mentioned module traction installation system is to install the module traction installation system in the construction area, wherein the front column, the rear column and the middle column are arranged according to the traction route, and the traction route passes through the designed location of the photovoltaic module; in the factory or on site, the pre-installed part of the guide rail assembly and the photovoltaic module are assembled together; the method also includes the following construction steps:

[0020] Step 1: at the starting point of the traction route, the photovoltaic modules connected to the pre-installed parts are installed one by one on the traction rope serving as the assembly rope behind the front crossbeam by connecting the on-site installation parts according to the designed spacing of the photovoltaic modules;

[0021] Step 2: After all the photovoltaic modules to be connected to the module rope are connected to the module rope, the traction winch is started again, and the photovoltaic modules on the module rope move forward together with the traction rope; the photovoltaic modules installed with the guide rail modules cross the supporting fixed pulley on the middle beam until they reach the designed location of the photovoltaic modules;

[0022] Step 3: Apply tension to the component cable to tension the component cable; after tensioning, temporarily fix the component cable on the front crossbeam and the rear crossbeam; cut off the traction cable; remove the supporting fixed pulleys on the middle crossbeam, the front crossbeam and the rear crossbeam;

[0023] Step 4: Install the component cable anchoring components on the front and rear cross beams to permanently anchor them, and install the component cable positioning components on the middle cross beam to permanently fix the component cables. The installation is complete.

[0024] Furthermore, in step 1, according to the size of the installation site at the starting point, the traction winch is started in batches to move the photovoltaic components installed on the traction rope serving as the component rope forward a certain distance, and the traction rope of the component rope is supplemented behind the front crossbeam to install subsequent photovoltaic components at the starting point.

[0025] 1. The traction-type installation method is adopted. The photovoltaic modules are installed only at one end of the flexible photovoltaic bracket (usually at the foot of the mountain or the bank of the pond). The modules only need to be transported to the starting point and installed at the starting point, at the foot of the mountain or the bank of the pond, etc., where the installation is convenient. There is no need to transport the modules to the pond or the mountain separately. This avoids the transportation and installation difficulties of the traditional flexible bracket installed on the cable, greatly improves the installation efficiency and safety, and reduces the installation cost.

[0026] 2. Installing a guide rail assembly under the photovoltaic module has the following beneficial effects: (1) Under the guidance of the guide rail assembly, the photovoltaic module can smoothly pass through the supporting fixed pulley under the action of traction, and the supporting fixed pulley can also play the role of lateral positioning of the photovoltaic module. (2) When the photovoltaic module passes through the supporting fixed pulley, due to the large tension of the cable, if the pulley directly contacts the photovoltaic module, it may damage the structure of the photovoltaic module. The guide rail assembly is set up to bear the force of the cable and the pulley, thereby avoiding damage to the photovoltaic module.

[0027] 3. Furthermore, the guide rail assembly adopts an I-shaped snap connection technology. The clearance height of the I-shaped snap is greater than the height of the fixed pulley slot, which is convenient for installation and connection. It can not only lock the assembly cable but also enable the entire sliding system to smoothly pass through the supporting fixed pulley slot.

[0028] 4. The technology of installing detachable supporting fixed pulleys on the middle beam and the end beam is adopted. The beneficial effects of this technology are as follows: (1) The supporting fixed pulley can prevent the photovoltaic module from colliding with the beam when crossing the beam; (2) After the traction is completed, the supporting fixed pulley and the pulley bracket can be removed and reused; (3) After the supporting fixed pulley and the pulley bracket are removed, the module rope falls onto the beam, and the module rope is permanently fixed to the beam, which makes it very convenient to switch from a temporary traction state to a permanent fixed state.
