Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a household intelligent automatic adjustment photovoltaic bracket system. Background Art

[0002] Photovoltaic power generation, as an important renewable energy source, has received widespread attention and use. With the continuous improvement and development of technology, the construction of photovoltaic power stations has gradually become smaller and gradually shifted to household roofs. As far as household roofs are concerned, photovoltaic brackets are basically fixed brackets or manually adjustable angle brackets.

[0003] The Chinese utility model patent with the publication number CN210536562U discloses a lightweight glass tile roof aluminum alloy photovoltaic bracket, which is mainly composed of two supporting brackets, a first connecting rod, a second connecting rod and an inclined beam. During installation, the threaded sleeve is rotated to make the second threaded rod support the first connecting rod and the second connecting rod, so as to adjust the tilt angle of the bracket as a whole. Since the photovoltaic module is in outdoor work for a long time, when heavy snow is required, the snow will cover the photovoltaic module. Although the photovoltaic module has a certain tilt angle during installation, the rear side of the photovoltaic module can be manually raised later to rotate the photovoltaic module around the fulcrum of the front section to increase the tilt angle of the photovoltaic module. However, the height that the rear end of the photovoltaic module can be raised and lowered is limited and the distance between the front and rear fulcrums is limited, so that the tilt angle of the photovoltaic module changes little. When the amount of snow on the photovoltaic module is small, it is not easy to slide, which greatly affects the conversion efficiency of the photovoltaic module. For this reason, we provide a household intelligent automatic adjustment photovoltaic bracket system to solve the above problems. Utility Model Content

The second guide mechanism and the third guide mechanism both adopt linear slide rails. The second driving mechanism can adopt driving components such as hydraulic cylinders or electric motors. For details, reference can be made to the linear slide rails of CNC machine tools, printing machines, and automated production lines. It is used to simultaneously move the rear column 7 of the bracket and the angle adjustment mechanism 5, and adjust the distance between the front column 4 of the bracket, the rear column 7 of the bracket, and the angle adjustment mechanism 5; the second driving mechanism and the adjustment mechanism 5 are respectively connected to the controller, and the controller adopts a PLC controller.

[0025] The angle adjustment mechanism 5 includes a box body, and heat dissipation holes can be opened on the top of the box body. The bottom of the box body is connected to the third guide mechanism. A lifting component 8 is installed in the box body, and the lifting component 8 is connected to the controller. The top of the lifting component 8 is connected to the rear column 7 of the bracket. One end of the top of the rear column 7 of the bracket extends to the outside of the box body and is connected to the second guide mechanism, which is used to adjust the inclination angle of the photovoltaic component 1, thereby achieving the purpose of remotely adjusting the inclination angle of the photovoltaic component 1 in real time.

[0026] The lifting assembly 8 includes two second connecting rods 803, one end of the bottom of the two second connecting rods 803 is hinged to the bottom of the inner side of the box body, the second connecting rod 803 and the box body are hinged to facilitate the rotation of the second connecting rod 803, one end of the top of the two second connecting rods 803 is hinged to a moving block 802, the second connecting rod 803 and the moving block 802 are hinged, and a driving structure is provided on the two moving blocks 802, and the driving structure is used to drive the two moving blocks 802 to move closer to or away from each other, and the tops of the two moving blocks 802 are respectively hinged to the first connecting rod 801, The first connecting rod 801 and the moving block 802 are hinged, the tops of the two first connecting rods 801 are hinged to the bottom of the rear column 7 of the bracket, the driving structure is connected to the controller, the first connecting rod 801 is hinged to the bottom of the rear column 7 of the bracket, the two first connecting rods 801, the two second connecting rods 803 and the two moving blocks 802 together form a rhombus. When in use, the bottom position of the rhombus is restricted, and then the two top ends in the middle of the rhombus are pulled or pushed closer or farther away from each other, thereby driving the top of the rhombus to move up and down, that is, the rear column 7 of the bracket moves up and down.

[0027] The driving structure includes a bidirectional threaded rod 804, which is connected to two moving blocks 802. The two moving blocks 802 are symmetrically arranged on the bidirectional threaded rod 804. The two moving blocks 802 are both provided with threaded through holes, and the threads of the through holes correspond to the threads of the bidirectional threaded rod 804. There are two kinds of threads on the surface of the bidirectional threaded rod 804, and the pitches are the same and the rotation directions are opposite. The threads of the through holes of the two moving blocks 802 correspond to the two kinds of threads on the bidirectional threaded rod 804 respectively. When in use, the bidirectional threaded rod 804 is rotated, and the moving blocks 802 are restricted from rotating by the second connecting rod 803 below, so that the moving blocks 802 are moved closer to or away from each other on the bidirectional threaded rod 804.

[0028] A driving assembly 10 is installed at the end of the bidirectional threaded rod 804. The driving assembly 10 adopts a servo motor to drive the bidirectional threaded rod 804 to rotate forward and reverse.

[0029] The angle adjustment mechanism 5 also includes a first guide mechanism, which is installed on the inner side of the side wall of the box body, and is connected to the drive assembly 10. A first drive mechanism is installed on the first guide mechanism.

The first drive mechanism is connected to the controller, and the controller for angle adjustment cooperates with the control of the first slide rail to match the movement of the slider on the track with the up and down speed driven by the drive assembly, so that the drive assembly 10 moves up and down on both sides, so that the position of the drive assembly 10 changes continuously to facilitate the heat dissipation of the drive assembly 10.

[0030] The photovoltaic module 1 is provided with an obstacle detection module 9, which is connected to the controller. The connection between the controller and other modules can be achieved by installing corresponding communication modules and adopting communication connection for information transmission. The obstacle detection module 9 can adopt an infrared laser obstacle detection sensor, which is distributed along the surface of the photovoltaic module 1 for parallel irradiation, and there is an appropriate distance between the irradiated laser beam and the photovoltaic module 1, which can be appropriately adjusted according to the effect of light shielding by snow accumulation in the area. When there is no obstruction, the laser beam is irradiated along the upper surface of the photovoltaic module 1 in parallel without laser reflection. When in use, the infrared laser obstacle detection sensor is used to irradiate the top of the photovoltaic module 1. When a certain thickness of snow accumulates on the photovoltaic module 1, the laser beam emitted by the infrared laser obstacle detection sensor is blocked, and a reflection signal is received, so that the infrared laser obstacle detection sensor detects the existence of an obstacle, and then feeds back the information to the controller. Finally, the snow is caused to slide down by increasing the tilt angle, thereby achieving the effect of clearing the snow. The infrared laser obstacle detection sensor can be intermittently turned on for detection according to actual conditions to reduce energy loss.

[0031] First, the device is installed on the top of the house as a whole through the bracket bottom beam 6. When the angle needs to be adjusted, the device is controlled by the controller to make the driving motor drive the two-way threaded rod 804 to rotate. Two moving blocks 802 are symmetrically arranged on the two-way threaded rod 804. The bottom of the moving block 802 is movably connected to the second connecting rod 803. The bottom of the second connecting rod 803 is movably connected to the bottom of the inner wall of the box body, thereby limiting the rotation of the moving block 802. Then the moving block 802 moves toward the middle along the two-way threaded rod 804. Since the bottom end of the second connecting rod 803 cannot move, when the top end of the second connecting rod 803 and the moving block 802 move horizontally, the moving block 802 and the two-way threaded rod 804 are driven to move upward at the same time.

[0032] The top of the moving block 802 drives one end of the bottom of the first connecting rod 801 to move horizontally, and one end of the top of the first connecting rod 801 is connected to the rear column 7 of the bracket, and the rear column 7 of the bracket passes through the top of the box, so that the top end of the first connecting rod 801 cannot move horizontally, and then with the lateral movement of the bottom end of the first connecting rod 801, the top of the first connecting rod 801 moves vertically, driving the rear column 7 of the bracket to move upward, and the top of the rear column 7 of the bracket is installed under the bracket inclined beam 3, so that one end of the bracket inclined beam 3 is raised, and the other end of the bracket inclined beam 3 is installed on the bracket bottom beam 6 through the bracket front column 4, so that the angle of the bracket inclined beam 3 changes, which further drives the tilt angle of the photovoltaic component 1 above to change and adjust to an appropriate angle to better receive light.

[0033] When there is snow accumulation, the obstacle detection component 9 is blocked, and then the obstacle detection component 9 transmits the blocked signal to the controller, and then controls the driving component 10 to work to increase the angle of the photovoltaic component 1. When the angle adjusted by raising the rear column 7 of the bracket is increased to the maximum, there is still snow accumulation, then the third guide mechanism on the bracket bottom beam 6 and the third guide mechanism on the bracket inclined beam 3 are controlled, so that the sliders on the second guide mechanism and the third guide mechanism respectively drive the angle adjustment mechanism 5 and the top of the bracket rear column 7 to move simultaneously, shortening the distance between the bracket front column 4 and the bracket rear column 7. Since the bracket rear column 7 has been raised to the highest point, the height of the bracket rear column 7 remains unchanged, and then as the bracket rear column 7 approaches the bracket front column 4, the angle of the bracket inclined beam 3 is further increased, so that the inclination angle of the photovoltaic component 1 is increased, and the snow slides off.
