[0003] The above prior art proposes that one end of the rear column is rotatably connected to the support plate, and the other end of the rear column slides along the extension direction of the base to adjust the pitch angle of the support plate, thereby realizing rapid angle adjustment of the photovoltaic bracket. However, there are still the following disadvantages:

[0005] 2. The mounting bracket used for household photovoltaics is difficult to adjust the angle of the device. Since the direction of the sun will change, it is difficult for the photovoltaic panels to always be exposed to the sun, and it is difficult to adjust the angle and direction of the photovoltaic panels to adapt to different situations.

[0006] 3. Birds like to stay on photovoltaic panels, and bird droppings will fall on them, which will affect the power generation efficiency of the photovoltaic panels and is not conducive to the cleaning of the photovoltaic panels. [Utility Model Content]

[0007] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a mounting bracket for household photovoltaic use, which solves the problems that photovoltaic panels are difficult to clean and have poor bird-repelling effect.

[0010] Preferably, the rotating block is rotatably supported on a side surface of the mounting block, and at least two connecting rods are distributed along the circumference of the rotating block, and the reflective plate is connected to the head end of the connecting rod.

[0011] Preferably, fixed plates are connected to the left and right sides of the upper end of the mounting block, a servo motor is installed on the outer side of one of the fixed plates, and the rotating shaft is rotatably supported on the other fixed plate.

[0012] Preferably, the guide rail is mounted on the lower end of the mounting block and is parallel to the threaded rod.

[0013] Preferably, an angle adjustment structure for adjusting the angle of the photovoltaic panel and a rotation mechanism for adjusting the orientation of the photovoltaic panel are provided between the base and the photovoltaic panel mounting structure.

[0014] Preferably, the angle adjustment structure includes a support frame, a first axis, a second axis, a telescopic rod assembly, and a movable groove. The support frame and the telescopic rod assembly are installed at the top of the rotating mechanism. The support frame is hinged to the lower side of the mounting block through the first axis. The top of the telescopic rod assembly is connected to the second axis. An adjusting slider is provided at the top of the second axis.

[0015] Preferably, the telescopic rod assembly includes a first telescopic rod, a second telescopic rod, a hydraulic cylinder and a hydraulic rod. The outer diameter of the second telescopic rod is smaller than the inner diameter of the first telescopic rod and the second telescopic rod can be telescoped inward and outward relative to the first telescopic rod. The top end of the second telescopic rod is connected to the second shaft. The hydraulic cylinder is arranged at the lower side of the first telescopic rod. The hydraulic rod connects the hydraulic cylinder and the second telescopic rod. When the hydraulic cylinder is working, it drives the hydraulic rod to extend and retract, and the hydraulic rod drives the second telescopic rod to rise and fall.

[0016] Preferably, the rotating mechanism comprises a rotating plate, a rotating motor, and a rotating shaft connecting the rotating plate and the rotating motor, and the rotating motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating plate to rotate.

[0017] Preferably, the rotating mechanism further comprises a guide rod and a guide groove, wherein the guide rod is connected to the rotating plate, and a guide slider is arranged at the bottom end of the guide rod, and when the rotating plate rotates, the guide slider slides along the guide groove.

[0018] The utility model adopts the above technical solution and has the following beneficial effects:

[0019] 1. The servo motor can drive the threaded rod to rotate when it is working. The threaded rod and the scraper form a threaded connection. Because the scraper cooperates with the guide rail, the threaded rod drives the scraper to move linearly along the guide rail and clean the surface of the photovoltaic panel when it rotates, which can remove dust and other debris on the surface of the photovoltaic panel;

[0020] The reflective plate is fixed in a normal position and can reflect light to drive away birds. In addition, the cleaning mechanism operates intermittently. When the threaded rod rotates, the rotating block can be driven to rotate through the transmission assembly. The rotation of the rotating block will drive the reflective plate to rotate. The rotation of the reflective plate can further improve the reflective bird-repelling effect.

[0021] Since the reflective board rotates to reflect light and repel birds more effectively, the cleaning mechanism operation time can be set at the time during the day when birds are most likely to approach the photovoltaic panels. This prevents birds from approaching the reflective board and photovoltaic panels and prevents bird droppings from falling on the photovoltaic panels.

[0022] Therefore, the utility model can achieve the purpose of facilitating the cleaning of photovoltaic panels by means of the cleaning mechanism and the reflective bird-repelling mechanism, thereby solving the problem that photovoltaic panels are difficult to clean and the bird-repelling effect is poor.

[0023] 2. When the threaded rod rotates, it can drive the rotating shaft to rotate, the rotation of the rotating shaft will drive the transmission belt to rotate, and the rotation of the transmission belt can drive the rotating block to rotate. In this way, the reflector and the threaded rod can be set at a certain distance, so that the threaded rod can be set at the upper end of the mounting block, and the rotating block is rotatably supported in the middle position of one of the left and right sides of the mounting block.

[0024] 3. At least two connecting rods are distributed along the circumference of the rotating block, and the reflective plates are connected to the head ends of the connecting rods, so that multiple reflective plates can be set to improve the reflective bird-repelling effect.

[0025] 4. Since fixed plates are connected to the left and right sides of the upper end of the mounting block, a servo motor is installed on the outer side of one of the fixed plates, the rotating shaft is rotatably supported on the other fixed plate, and the guide rail is installed at the lower end of the mounting block and is parallel to the threaded rod, the installation of the cleaning mechanism can be facilitated.

[0026] 5. An angle adjustment structure for adjusting the angle of the photovoltaic panel and a rotation mechanism for adjusting the direction of the photovoltaic panel are provided between the base and the photovoltaic panel mounting structure, so as to adjust the angle and direction of the photovoltaic panel.

[0027] The mounting block in the angle adjustment structure can rotate along the first axis, and the first telescopic rod and the second telescopic rod constitute a telescopic sliding structure. The operation of the hydraulic cylinder can drive the hydraulic rod to extend and retract, and the extension and retraction of the hydraulic rod can drive the second telescopic rod to rise and fall. When the second telescopic rod is lifted and lowered, it will drive one side of the mounting block to rise or fall, and at the same time, the other side of the mounting block will rotate along the first axis, and the second axis at the top of the second telescopic rod can rotate, and at the same time it will slide along the moving groove, so that the mounting block can be raised and lowered without being affected.

[0028] In the rotating mechanism, the rotating motor can drive the rotating shaft to rotate, and the rotation of the rotating shaft can drive the rotating plate to rotate. The rotation of the rotating plate can adjust the direction of the photovoltaic panel so that the photovoltaic panel can adapt to different situations. The guide rod and guide groove at the bottom of the rotating plate constitute a rotating sliding structure. When the rotating plate rotates, the guide rod will also slide along the guide groove, and the guide rod can guide the rotation of the rotating plate.

The reflective bird-repelling mechanism includes a rotating block 6038, a connecting rod 6039 connected to the rotating block, and a reflective plate 6037 connected to the connecting rod. A transmission assembly is provided between the rotating block 6038 and the threaded rod 6033, so that when the threaded rod rotates, the rotating block is driven to rotate, and the reflective plate is driven to rotate through the connecting rod to perform reflective bird-repelling.

When the threaded rod rotates, the rotating block can be driven to rotate through the transmission assembly. The rotation of the rotating block will drive the reflective plate to rotate. The rotation of the reflective plate can improve the reflective bird-repelling effect.

[0044] Since the reflective board rotates to reflect light and repel birds more effectively, the cleaning mechanism operation time can be set at the time during the day when birds are most likely to approach the photovoltaic panels.
