Description

Technical Field

[0001] The utility model relates to the field of photovoltaic modules, in particular to a fixed and adjustable bracket for photovoltaic modules. Background Art

[0002] Photovoltaic modules generally refer to solar cell modules. Since the output voltage of a single solar cell is relatively low, and the electrodes of the unencapsulated battery are prone to falling off due to environmental influence, a certain number of single cells must be sealed into a solar cell module in series and parallel to avoid corrosion of the battery electrodes and interconnections. In addition, encapsulation also prevents the battery from cracking, facilitating outdoor installation. The quality of encapsulation determines the service life and reliability of the solar cell module.

[0003] Due to the different angles of sunlight irradiation in the four seasons, the inclination angles required for photovoltaic modules are different. Therefore, it is necessary to adjust the inclination angle of the photovoltaic modules so that the light can directly irradiate the photovoltaic modules, thereby improving the power generation efficiency of the photovoltaic modules. Existing photovoltaic modules can rotate, generally also individually, so only one photovoltaic module can be rotated one by one, and the rotation speed is very slow. For this reason, a fixed and adjustable bracket for photovoltaic modules is needed to enable a row of photovoltaic modules to rotate simultaneously, facilitating the adjustment of the inclination angle of the photovoltaic modules. Summary of the Utility Model

A rotating shaft is rotatably connected to the inner side wall of the bracket main body. A support plate is connected to the side wall of the rotating shaft, and a photovoltaic module main body is installed on the support plate. Both ends of the rotating shaft penetrate through the bracket main body. One end of the rotating shaft located at the outermost edge is connected to a driving mechanism, one end of the rotating shaft is connected to a connecting mechanism, a limiting mechanism is arranged on the bracket main body, and an auxiliary mechanism is installed on the bracket main body;

[0006] The driving mechanism includes a base and a motor. The top end of the base is connected to the motor, and the output end of the motor is connected to one end of the rotating shaft located at the outermost edge;

A plurality of limiting holes are arranged in an array of circular shafts on the side walls at both ends of the rotating shaft. A support block is arranged on one side wall of the main body of the bracket. A limiting rod is threadedly connected to the side wall of the support block, and one end of the limiting rod penetrates through the side wall of the support block.

[0010] Preferably, one end of the limiting rod faces the side of the limiting hole.

[0011] Preferably, the auxiliary mechanism includes a bottom plate, a guide rod, a connecting plate and a screw rod. The bottom end of the side wall of the main body of the bracket is connected with a bottom plate. The side wall of one of the bottom plates located at the center is threadedly connected with a screw rod. The side walls of the remaining bottom plates are slidably connected with a guide rod. One end of the guide rod is connected with the connecting plate. The side wall of the screw rod is rotatably connected with the connecting plate.

[0014] Preferably, a retaining cap is threadedly connected to the end of the guide rod away from the connecting plate.

[0029] Refer to the attached Figure 1-7, a fixed and adjustable bracket for a photovoltaic module, comprising a bracket main body 2 installed on a base 1. A rotating shaft 5 is rotatably connected to the inner side wall of the bracket main body 2. A support plate 3 is connected to the side wall of the rotating shaft 5. A photovoltaic module main body 4 is installed on the support plate 3. Both ends of the rotating shaft 5 penetrate through the bracket main body 2. One end of the rotating shaft 5 at the outermost edge is connected to a driving mechanism 6, and one end of the rotating shaft 5 is connected to a connecting mechanism 7. A limiting mechanism 8 is provided on the bracket main body 2, and an auxiliary mechanism 9 is installed on the bracket main body 2;

[0030] The driving mechanism 6 includes a base 601 and a motor 602. The top end of the base 601 is connected to the motor 602, and the output end of the motor 602 is connected to one end of the rotating shaft 5 at the outermost edge;

[0031] The connecting mechanism 7 includes a connecting pipe 701, a pin 702, a nut 703 and a through hole 704. Through holes 704 are provided on the side walls of both ends of the rotating shaft 5 and the side wall of the connecting pipe 701. A pin 702 is inserted and connected in the through hole 704. The bottom end of the pin 702 is threadedly connected to a nut 703. One end of the rotating shaft 5 is inserted into the connecting pipe 701, and a solid rod can be filled inside the connecting pipe 701.

[0032] Connect the output end of the motor 602 to one end of the rotating shaft 5 at the outermost edge. Sleeve both ends of the connecting pipe 701 on one end of two adjacent rotating shafts 5 respectively, and align the through hole 704 on the connecting pipe 701 with the through hole 704 on the rotating shaft 5. Insert the pin 702 into the through hole 704, and screw the nut 703 into the bottom of the pin 702, so as to connect two adjacent rotating shafts 5 together, so that the two rotating shafts 5 can rotate synchronously, and so on, to connect adjacent rotating shafts 5. At this time, place the bracket main body 2 and the rotating shaft 5 in a horizontal array. At this time, start the motor 602. The motor 602 drives one of the rotating shafts 5 to rotate, which can drive all the rotating shafts 5 to rotate. The rotating shaft 5 drives the support plate 3 to rotate, thereby driving the photovoltaic module main body 4 to rotate, so as to achieve the effect of simultaneously adjusting the inclination angles of multiple photovoltaic module main bodies 4. Use the limiting mechanism 8 to limit the rotating shaft 5. When the rotating shaft 5 does not move, the support plate 3 is fixed, so as to ensure the stable fixation of the photovoltaic module main body 4.

[0033] Refer to the appendix Figure 5-6 , the limiting mechanism 8 includes a support block 801, a limiting rod 802 and a limiting hole 803. A plurality of limiting holes 803 distributed in a circular shaft array are provided on the side walls of both ends of the rotating shaft 5.

One end of the limiting rod 802 penetrates through the side wall of the support block 801, and one end of the limiting rod 802 faces the side of the limiting hole 803.

[0034] When the auxiliary mechanism 9 is not connected to the support block 801, that is, when the auxiliary mechanism 9 is not provided, the support block 801 is fixedly connected to the support body 2. At this time, when the limit rod 802 is rotated, the limit rod 802 can be inserted into the limit hole 803, thereby restricting the rotation of the rotating shaft 5. By using the multiple limit holes 803 provided, it can be ensured that the inclination angle of the support plate 3 can meet the requirement of the inclination angle required by the photovoltaic module body 4.

One end of the guide rod 902 is connected with the connecting plate 903, and the side wall of the screw rod 904 is rotatably connected with the connecting plate 903. The top end of the connecting plate 903 is connected with the support block 801. A screw hole is provided on the side wall of one of the bottom plates 901, and the screw hole is threadedly connected with the screw rod 904. Circular holes are provided on the side walls of the remaining bottom plates 901, and the inner side walls of the circular holes are slidably connected with the guide rod 902. The connecting plate 903 is composed of a plurality of U-shaped plates and a cross plate. The two ends of the cross plate are respectively connected with the opposite side walls of two adjacent U-shaped plates. A retaining cap is threadedly connected to the end of the guide rod 902 away from the connecting plate 903. The top end of the U-shaped plate is connected with the support block 801. The screw hole and the circular hole are both located on the U-shaped plate.

[0036] When the auxiliary mechanism 9 is connected to the support block 801, that is, when the connecting plate 903 is connected to the support block 801, the support block 801 is not connected to the support body 2. At this time, when the screw rod 904 is rotated, the screw rod 904 can drive the connecting plate 903 to move. The connecting plate 903 drives the support block 801 to move, and the support block 801 drives the limit rod 802 to be inserted into the limit hole 803, thereby realizing the effect of simultaneously fixing a plurality of rotating shafts 5.
