Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a multifunctional mounting bracket for photovoltaic modules. Background Technology

[0002] A single solar cell cannot be used directly as a power source. To use it as a power source, several individual cells must be connected in series and parallel and tightly packaged into a module. Photovoltaic modules, also called solar panels, are the core and most important part of a solar power generation system. Their function is to convert solar energy into electrical energy and send it to batteries for storage or to power loads. The mounting brackets of photovoltaic modules are used to support the photovoltaic modules so that they face the sun and generate electricity.

[0003] Existing photovoltaic (PV) module mounting brackets, after fixing the PV panels, can usually adjust the angle of the PV panels according to needs. Some mounting brackets can also be adjusted according to the size of the PV modules, thereby fixing PV modules of different sizes. For example, Chinese Patent Publication No. CN222301672U discloses "a PV module mounting bracket", which pulls the first connecting plate and the second connecting plate to a designated position according to the size specifications of the PV module. Then, the corresponding bolts and the first nut are tightened with tools to fix the position of the second connecting plate and the first connecting plate. The distance between the first support component and the second support component is adjusted to adjust the size specifications of the mounting bracket, thereby expanding the applicability of the mounting bracket. It eliminates the need to customize brackets of corresponding specifications, enhancing practicality and economy. The corresponding PV modules are installed on the mounting block using corresponding fasteners.

[0004] However, in actual use, the process of adjusting the bracket is quite complicated, and fasteners are needed to fix the photovoltaic modules on the bracket, which is cumbersome and affects the installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the complicated process of adjusting the bracket and the need for fasteners to fix the photovoltaic modules on the bracket, which is cumbersome and affects the installation efficiency. The proposed multi-functional mounting bracket for photovoltaic modules is to solve these problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional mounting bracket for photovoltaic modules is designed, including a mounting frame and two connecting frames. Each connecting frame is rotatably equipped with a support rod. A connecting rod is provided between the two support rods and the two connecting frames. A fixing rod is also provided between the two support rods. An adjustment component is provided between the two connecting rods. A connecting plate is provided on the mounting frame. A pressure plate is slidably connected to the mounting frame through a connecting mechanism. A driving component is provided on the connecting mechanism. A base is provided at the lower end of each support rod. A lifting structure is provided between the base and the support rod.

[0008] Furthermore, the adjusting assembly includes a connecting block rotatably connected to the connecting rod, and each of the two connecting blocks is fixedly provided with a screw, and a threaded sleeve is threadedly connected between the two screws.

[0009] Furthermore, the connecting mechanism includes a lifting groove formed on the mounting frame, a support plate fixedly disposed in the lifting groove, and a connecting frame that is movably inserted into the support plate fixedly disposed on the pressure plate.

[0010] Furthermore, the drive assembly includes a traction rope fixedly connected to the connecting frame, the lower end of the traction rope being fixedly provided with a threaded portion, and a counterweight being threadedly connected to the threaded portion.

[0011] Furthermore, both the fixing rod and the connecting rod are equipped with pulleys, and each pulley has a guide groove that cooperates with the traction rope.

[0012] Furthermore, the lifting structure includes an insert plate fixedly mounted on the base, the insert plate being movably connected to the support rod, and multiple through holes being provided on both the support rod and the insert plate, and the support rod also having bolt and nut assemblies that cooperate with the through holes.

[0013] The multifunctional mounting bracket for photovoltaic modules proposed in this utility model has the following advantages:

[0014] In this invention, the position of the pressure plate is controlled by the cooperation of the drive component and the connecting mechanism, so that the pressure plate is continuously subjected to a downward force, thereby ensuring that the pressure plate presses and fixes the photovoltaic module. At the same time, when the specifications of the photovoltaic module change, the position of the pressure plate when pressing also changes, adapting to photovoltaic modules of different specifications, making the installation of photovoltaic modules more convenient and efficient.

[0015] Secondly, in this invention, by adjusting the components to control the mounting frame and the angle of the photovoltaic modules on the mounting frame, it is convenient to calibrate the angle of the photovoltaic panels and improve the power generation efficiency of the photovoltaic modules.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A multi-functional mounting bracket for photovoltaic modules includes a mounting frame 1 and two connecting frames 2. The photovoltaic bracket is placed on the mounting frame 1. Each connecting frame 2 is rotatably equipped with a support rod 3. A connecting rod 21 is provided between the two support rods 3 and the two connecting frames 2. An adjustment component 4 is provided between the two connecting rods 21. A fixing rod is also provided between the two support rods. A connecting plate 5 is provided on the mounting frame 1. A pressure plate 7 is slidably connected to the mounting frame 1 through a connecting mechanism 6. The pressure plate 7 has a limiting part. The pressure plate 7 and the limiting part form an L-shaped structure to hook the photovoltaic module and prevent it from separating and falling off the mounting frame 1. A drive component 8 is provided on the connecting mechanism 6. A base 31 is provided at the lower end of the support rod 3. A lifting structure 32 is provided between the base 31 and the support rod 3.

[0023] In this utility model, apart from the traction rope, all other components are made of stainless steel or coated with anti-rust paint. The position of the pressure plate 7 is controlled by the drive component 8 and the connecting mechanism 6, so that the pressure plate 7 is continuously subjected to downward force, thereby ensuring that the pressure plate 7 presses and fixes the photovoltaic module. At the same time, when the specifications of the photovoltaic module change, the position of the pressure plate 7 when it moves down to press also changes, thereby adapting to photovoltaic modules of different specifications, making the installation of photovoltaic modules more convenient and efficient.

[0024] Furthermore, in this embodiment, the adjustment component 4 includes a connecting block 41 rotatably connected to the connecting rod 21. Each of the two connecting blocks 41 is fixedly provided with a screw 42, and a threaded sleeve 43 is threadedly connected between the two screws 42. The threaded sleeve 43 is a bidirectional threaded sleeve. When the threaded sleeve 43 rotates, the two screws 42 move away from each other or move towards each other, thereby changing the distance between the two connecting rods 21, and thus changing the angle of the mounting frame 1 and the photovoltaic module.

[0025] Furthermore, in this embodiment, the connecting mechanism 6 includes a lifting groove 61 opened on the mounting frame 1, a support plate 62 is fixedly installed in the lifting groove 61, and a connecting frame 63 that is movably inserted into the support plate 62 is fixedly installed on the pressure plate 7. The connecting frame 63 and the pressure plate 7 can move up and down along the support plate 62. When installing the photovoltaic module, the pressure plate 7 is moved up first. After the installation is completed, the driving component 8 is connected to drive the pressure plate 7 to press and fix the photovoltaic module.

[0026] It should be noted that in this embodiment, the drive component 8 includes a traction rope 81 fixedly connected to the connecting frame 63. The lower end of the traction rope 81 is fixedly provided with a threaded part 82, and a counterweight 83 is threadedly connected to the threaded part 82. The counterweight 83 is suspended in the air and does not contact the ground. The gravity of the counterweight 83 will pull the traction rope 81, and the traction rope 81 will pull the connecting frame 63 and the pressure plate 7 to move down to fix the photovoltaic module. When installing the photovoltaic module, the counterweight 83 can be removed first to reduce the difficulty of moving the pressure plate 7 up.

[0027] Furthermore, in this embodiment, both the fixed rod 22 and the connecting rod 21 are equipped with pulleys 84, and each pulley 84 has a guide groove that cooperates with the traction rope 81. By setting the pulleys 84, the traction rope 81 and the connecting rod 21 are prevented from rubbing against each other. At the same time, the counterweight 83 cooperates with the traction rope 81, which is equivalent to configuring a tuned mass damper on the connecting rod 21 to absorb the kinetic energy generated by the north wind blowing on the mounting bracket and increase the windproof and vibration-resistant performance of the mounting bracket.

[0028] More specifically, in this embodiment, the lifting structure 32 includes an insert plate 321 fixedly mounted on the base 31. The insert plate 321 is movably inserted into the support rod 3. Both the support rod 3 and the insert plate 321 have multiple through holes 322. The support rod 3 is also provided with a bolt and nut assembly 323 that cooperates with the through holes 322. By changing the insertion range of the insert plate 321, the height of the support rod 3 can be changed and fixed by the bolt and nut assembly 323. The bolt and nut assembly 323 includes a bolt passing through the through hole and a nut threadedly connected to the bolt.

[0029] Working method: During operation, first remove the counterweight 83, move the pressure plate 7 upward to place the photovoltaic module on the mounting frame 1, rotate the threaded sleeve 43 to change the distance between the two connecting rods 21, thereby changing the angle of the mounting frame 1 and the photovoltaic module. After calibrating the angle, pass the traction rope 81 through the guide groove of the two pulleys 84, and connect the counterweight 83 to the threaded part 82 of the traction rope 81. The gravity of the counterweight 83 will pull the traction rope 81, and the traction rope 81 will pull the connecting frame 63 and the pressure plate 7 downward to clamp and fix the photovoltaic module.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
