Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, in particular to a mounting base for photovoltaic modules. Background Art

[0002] Since the output voltage of a single solar cell is relatively low, and the electrodes of the unencapsulated cell are prone to falling off due to environmental influences, a certain number of single cells must be connected in series and parallel and sealed into a solar cell module to prevent the cell electrodes and interconnections from being corroded. In addition, encapsulation also prevents the cells from being broken and facilitates outdoor installation. The quality of encapsulation determines the service life and reliability of the solar cell module.

[0003] As disclosed in the utility model with the authorization announcement number CN221305843U, a frame of a solar panel group drives a second lead screw to rotate through a rotation adjusting member, thereby controlling the connecting column to move along the direction of the second lead screw, and then controlling the clamping plate to clamp and fix towards the solar panel. When disassembling, just reverse the adjusting member, making the installation and disassembly of the solar panel more convenient and facilitating the later maintenance work. The clamping plate is of an inverted L-shaped structure, so that the horizontal plate of the clamping plate can abut against the upper surface of the solar panel to prevent the solar panel from bulging upwards. A new groove can be formed by the limiting plate and the three inner walls of the installation groove. After the solar panel is installed, one end of the solar panel will be inserted into this groove, which can strengthen the stability of the solar panel after installation.

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present utility model.

[0025] Embodiment

[0026] Please refer to Figure 1 、 Figure 3 and Figure 5 As shown, the present utility model provides a mounting base for a photovoltaic module, including a foot 2 for fixing the base. The device is installed at a suitable position through the foot 2. A motor box 21 is installed inside the foot 2. The output end of the servo motor in the motor box 21 is installed with a threaded rod 12. The outer side of the threaded rod 12 is threadedly connected with a lifting block 71. Three sides of the outer side of the lifting block 71 are provided with sliding grooves. A guide rail 13 matching the sliding grooves is arranged inside the support frame 1. By rotating the threaded rod 12, the lifting block 71 can be driven to move up and down along the guide rail 13. A cross bar 7 is installed between two groups of lifting blocks 71 on both sides of the support frame 1. The cross bar 7 is inserted into the rotation hole 41 at the bottom of the baffle 4. The connection mode between the baffle 4 and the cross bar 7 is a rotational connection. The lifting assembly includes a lifting block 71, a threaded rod 12 and a motor box 21. The top and bottom ends of the threaded rod 12 are connected to the motor box 21 and the support frame 1 through bearings. A top limit plate 11 is arranged at the top of the support frame 1. A limit guide bar 44 capable of moving along the limit groove inside the top limit plate 11 is installed outside the limit guide bar 44. When the baffle 4 is in a vertical state, the limit guide bar 44 is in the limit groove of the top limit plate 11. By allowing the limit guide bar 44 to move along the limit groove, the movement track of the baffle 4 is restricted;

[0027] Specifically, turn on the servo motor in the motor box 21 to drive the threaded rod 12 to rotate. The rotating threaded rod 12 drives the lifting block 71 to move along the guiding slide rail 13, driving the shielding plate 4 to rise, and enabling the limiting guide strip 44 to move upward along the limiting groove inside the top limiting plate 11. When it is necessary to lower the shielding plate 4, reverse the rotation of the servo motor in the motor box 21;

[0028] Please refer to Figures 1-4 As shown, a fixing seat 42 is provided inside the shielding plate 4. A rotating rod 43 is provided inside the fixing seat 42. The rotating rod 43 can rotate within the fixing seat 42. A notch is provided at the middle position of the rotating rod 43. The electromagnet connector 6 fits with the notch of the rotating rod 43. After the electromagnet connector 6 is powered on, it magnetically adheres to the rotating rod 43. The rotating rod 43 is made of metal. The electromagnet connector 6 is installed at the output end of the pneumatic rod 5. A through hole is provided at the tail of the fixed end of the pneumatic rod 5. The fixed end is rotatably connected to the rotating seat 51. The rotating seat 51 is installed on the support frame 1. The rotation adjustment assembly includes the fixing seat 42, the rotating rod 43, the pneumatic rod 5, the rotating seat 51, and the electromagnet connector 6. By changing the air pressure inside the pneumatic rod 5, it is possible to drive the shielding plate 4 to rotate along the cross bar 7 to change the angle between the shielding plate 4 and the photovoltaic panel 3, facilitating the opening and closing of the shielding plate 4. The electromagnet connector 6 is connected to the notch of the rotating rod 43, and the electromagnet connector 6 magnetically adheres to the rotating rod 43, enabling the electromagnet connector 6 and the rotating rod 43 to be an integral body when the output end of the pneumatic rod 5 extends, facilitating driving the shielding plate 4 to rotate along the cross bar 7 by changing the output end length of the pneumatic rod 5;

[0029] Specifically, increase the output end length of the pneumatic rod 5. The electromagnet connector 6 is powered on and magnetically adheres to the notch of the rotating rod 43, driving the shielding plate 4 to rotate along the cross bar 7, opening the shielding plate 4 to both sides and exposing the photovoltaic panel 3 inside. When the shielding plate 4 is rotated to a state perpendicular to the photovoltaic panel 3, the limiting guide strip 44 on the back of the shielding plate 4 enters the limiting groove inside the top limiting plate 11, and the top limiting plate 11 limits the maximum rotation angle of the shielding plate 4. Cooperating with the lifting assembly, the shielding plate 4 moves downward along the gap between the support frame 1 and the top limiting plate 11. During the movement, the length of the pneumatic rod 5 changes accordingly. When the pneumatic rod 5 is parallel to the photovoltaic panel 3, cut off the power supply of the electromagnet connector 6, so that the electromagnet connector 6 and the rotating rod 43 can be separated. Due to its own gravity, the notch of the separated rotating rod 43 is always in the upward-facing state; when it is necessary to remove the shielding plate 4 for use, during the rising process of the shielding plate 4, the output end of the pneumatic rod 5 extends to move the electromagnet connector 6 to a suitable position. When the fixing seat 42 and the rotating rod 43 move out of the surface of the support frame 1, the notch of the rotating rod 43 contacts the electromagnet connector 6, and the electromagnet connector 6 is powered on to generate magnetic suction and adsorb the rotating rod 43. When the shielding plate 4 is completely removed, contract the output end length of the pneumatic rod 5 to pull the two-sided shielding plate 4 to close and cover the photovoltaic panel 3;

[0030] Specific working principle:

[0031] When it snows, the servo motor in the motor box 21 rotates, driving the lifting block 71 to slide in the support frame 1, driving the shielding plate 4 to rise. At the same time, the air pressure in the air pressure rod 5 is increased, increasing the output end length of the air pressure rod 5, so that the electromagnet connector 6 and the notch of the rotating rod 43 are on the same vertical line perpendicular to the photovoltaic panel 3. After the rotating rod 43 moves out, the electromagnet connector 6 gets stuck in the notch of the rotating rod 43. The electromagnet connector 6 is energized to generate magnetic suction, adsorbing the rotating rod 43. The shielding plate 4 continues to rise, and the air pressure of the air pressure rod 5 synchronously increases. The shielding plate 4 moves to the highest position, and the air pressure rod 5 contracts the output end length, driving the shielding plate 4 to rotate along the cross bar 7 and covering the photovoltaic panel 3. When the snow stops and it is sunny, the increase in the output end of the air pressure rod 5 drives the shielding plate 4 to rotate in the reverse direction, opening the shielding plate 4 to both sides to a state perpendicular to the photovoltaic panel 3, allowing the limiting guide strip 44 to enter the limiting groove in the top limiting plate 11. At this time, most of the snow on the shielding plate 4 will fall off under the action of its own gravity and be removed. The remaining snow melts under the sun's irradiation. At this time, the photovoltaic panel 3 works to convert solar energy into electrical energy and store it in the storage battery. Lower the shielding plate 4, reverse the rotation of the servo motor in the motor box 21, driving the shielding plate 4 to descend. When the electromagnet connector 6 is parallel to the photovoltaic panel 3, cut off the power supply to the electromagnet connector 6, power off the electromagnet connector 6, separate the electromagnet connector 6 and the rotating rod 43, and retract the shielding plate 4.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
