Description

Technical Field

[0001] The invention belongs to the technical field of solar panel mounting racks, in particular to a portable solar panel mounting rack. Background Art

[0002] With the continuous development of solar technology, portable solar panels have been widely used in various scenarios due to their flexible mobility and easy installation, such as field operations, emergency rescue, outdoor leisure, etc. The existing portable solar panel mounting racks mainly include the following types:

[0003] Folding mounts: These types of mounts typically consist of multiple foldable brackets that unfold when in use and fold away when not in use. They are relatively simple in structure and easy to carry and transport. Some folding mounts also feature adjustable brackets, allowing for adjustments based on terrain and sunlight angles.

[0004] Lifting mount: This type of mount can realize the lifting function of the solar panel by electric or manual means. When the height of the solar panel needs to be adjusted, the solar panel can be raised or lowered through the lifting mechanism to adapt to different installation environments and usage requirements. Some lifting mounts also have automatic control functions, which can automatically adjust the height and angle of the solar panel according to the angle of sunlight;

[0005] Rotating mount: The rotating mount allows the solar panel to rotate horizontally. Through motor or manual operation, the solar panel can rotate with the movement of the sun, thereby improving the efficiency of solar energy collection. Some rotating mounts are also combined with lifting functions to further optimize the angle adjustment range of the solar panel.

[0006] However, existing portable solar panel mounts are prone to shaking or even collapsing and damage when encountering severe weather such as strong winds due to limitations in their structural design and fixing methods.

[0015] 1. The wind speed data measured is transmitted to the data acquisition module in the support frame through the wind measuring mechanism. The data acquisition module processes and analyzes the data. At the same time, the slider slides in the slide rail according to the centrifugal force generated by the wind speed. The position information of the slider is collected by the sensor and transmitted to the data acquisition module. The control unit makes a judgment based on the wind speed and slider position information collected by the data acquisition module.

The wind measuring mechanism monitors the wind speed and direction in real time, and automatically adjusts the angle and height of the solar panel according to the situation, so that it can better cope with strong winds, reduce the risk of being blown down or damaged by strong winds, and improve the safety and stability of the solar panel in bad weather. The bottom of the solar panel body is lower than the baffle, and strong winds can pass over the solar panel, reducing the force of strong winds directly acting on the solar panel, avoiding damage to the solar panel caused by shaking or collision due to strong winds, and extending the service life of the solar panel. The setting of the data acquisition module and the control unit realizes the automatic operation of the entire system without manual intervention. It can automatically adjust the status of the solar panel according to real-time wind speed and direction information, improving the convenience and efficiency of use.

[0026] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0027] like Figure 1-Figure 7 As shown, the present invention provides a technical solution:

[0028] A portable solar panel mounting rack comprises a solar panel main body 1, a connecting rack 2 is installed at the bottom of the solar panel main body 1, a plurality of retractable support legs 3 are rotatably connected to the bottom of the connecting rack 2, a mounting rack main body 5 is rotatably connected to the bottom of the retractable support legs 3, a motor 17 is installed in the bottom plate 6, an output end of the motor 17 is coaxially fixedly connected to a rotating block 18, a fixing rack 7 is installed on the top of the mounting rack main body 5, the rotating block 18 is fixedly connected to the fixing rack 7, an electric telescopic rod 9 is installed on the top of the fixing rack 7, the output end of the electric telescopic rod 9 is fixedly connected to the bottom of the connecting rack 2, and the electric telescopic rod 9 is located at the center of the solar panel main body 1, the connecting rack 2 A support frame 10 is installed on one side of the bottom, and a wind measuring mechanism 11 is rotatably connected to the top of the support frame 10. A slide rail 12 is installed on the outer side of the bottom of the wind measuring mechanism 11, and a slider 13 is slidably connected in the slide rail 12. A counterweight is provided on the outside of the slider 13, and a second spring 25 is fixedly installed between the slider 13 and the slide rail 12. A sensor 14 used in conjunction with the slider 13 is installed on the outermost side of the slide rail 12. A baffle 8 is snap-fitted to the outer side of the fixing frame 7. The baffle 8 is located at the lowest position of the solar panel body 1. The wind measuring mechanism 11 is a three-cup anemometer, and a data acquisition module and a control unit used in conjunction with the wind measuring mechanism 11, the sensor 14, the electric telescopic rod 9 and the motor 17 are provided in the support frame 10;

[0029] Specifically, when in use, the wind measuring mechanism 11 adopts a three-cup anemometer, which can measure wind speed and wind direction in real time. When wind blows, the cups of the three-cup anemometer will rotate, and their rotation speed is related to the wind speed, so that the size and direction of the wind speed can be sensed. The wind measuring mechanism 11 transmits the measured wind speed data to the data acquisition module in the support frame 10, and the data acquisition module processes and analyzes the data. At the same time, the slider 13 will slide in the slide rail 12 according to the centrifugal force generated by the wind speed. The position information of the slider 13 is collected by the sensor 14 and transmitted to the data acquisition module. The control unit makes a judgment based on the wind speed and the position of the slider 13 collected by the data acquisition module. When the wind speed reaches the set threshold, the control unit will issue an instruction. If the control unit determines that the solar panel needs to be adjusted to cope with strong winds, it will control the motor 17 to start, and the motor 17 drives the rotating block 18 to rotate. The rotating block 18 is connected to the fixed frame 7, so that the fixed frame 7 rotates together with the solar panel body 1, so that the surface of the solar panel caters to the blowing surface. At the same time, the control unit will control the electric telescopic When the wind speed drops below the limit, the solar panel will automatically return to its normal working angle and height. The wind measuring mechanism 11 monitors the wind speed and direction in real time and automatically adjusts the angle and height of the solar panel according to the situation, so that the solar panel can better cope with strong winds and reduce the risk of being blown down or damaged by strong winds. The safety and stability of the solar panel in severe weather are improved. When the solar panel main body 1 is lower than the baffle 8, strong winds can pass over the solar panel, reducing the force of strong winds directly acting on the solar panel, avoiding the solar panel from shaking or colliding due to strong winds and damaging it. The service life of the solar panel is extended. The data acquisition module and the control unit are set to realize the automatic operation of the entire system without manual intervention. The system can automatically adjust the state of the solar panel according to the real-time wind speed and direction information, thereby improving the convenience and efficiency of use.

[0030] The mounting frame body 5 includes a first fixing rod 501 and multiple sets of second fixing rods 502. The fixing frame 7 is fixed to the top of the first fixing rod 501. The second fixing rods 502 are symmetrically located on both sides of the first fixing rod 501. The first fixing rod 501 is symmetrically fixed with telescopic blocks 504 on both sides. The output end of the telescopic block 504 is connected to the outer side of the telescopic second fixing rod 502. The first fixing rod 501 and the second fixing rod 502 are both slidably connected with a connecting block, and the outer side of the connecting block is rotatably connected with a connecting rod 23. The connecting rod 23 is cross-shaped and located between the first fixing rod 501 and the second fixing rod 502. An air pump 15 is installed on the top of the fixing frame 7 on one side of the electric telescopic rod 9. The first fixing rod 501 and the second fixing rod 502 are both symmetrically connected with piston blocks 20. The outside of the piston block 20 is connected to a movable rod, and a push block 22 is fixedly installed on the outer end of the movable rod. An extension rod 503 is installed on the outside of the push block 22. The extension rod 503 is located on the outside of the first fixing rod 501 and the second fixing rod 502 and is slidably connected thereto. An air supply pipe 16 is connected between the second fixing rod 502, and the air supply pipe 16 is connected to the air pump 15. The air supply pipe 16 is located in the middle position inside the second fixing rod 502.

[0031] Specifically, when the mounting frame body 5 is in the folded state, the air pump 15 is not started, the piston block 20 is in the initial position, the first spring 21 is in a natural state or a slightly compressed state, the extension rod 503 is retracted to the inside of the second fixing rod 502, the cross-shaped connecting rod 23 is folded, the distance between the first fixing rod 501 and the second fixing rod 502 is minimized, the overall volume is compact, and it is easy to carry and transport. When installation is required, the air pump 15 is started to supply compressed air to the air pipe 16, and the compressed air enters the interior of each second fixing rod 502 synchronously through the air pipe 16. The air pressure pushes the piston block 20 to move outward, driving the movable rod and the push block 22, and the push block 2 2 overcomes the resistance of the first spring 21, pushes the extension rod 503 to slide outward, and by pulling the telescopic block 504, the connecting rod 23 slides and expands in the second sliding groove 24 of the first fixed rod 501 and the second fixed rod 502. The second fixed rod 502 is synchronously expanded outward by the telescopic block 504, thereby increasing the diameter of the support base. When it needs to be retracted, the air pump 15 reverses the air pumping or releases the pressure. The elastic force of the first spring 21 pushes the push block 22 inward, and the piston block 20, the movable rod and the extension rod 503 retract synchronously. The connecting rod 23 folds, and the distance between the first fixed rod 501 and the second fixed rod 502 is reduced, and the supporting base is restored to the folded state.

[0032] A first spring 21 is fixedly installed on the inner side of the push block 22 and the outermost side of the second fixing rod 502. The first spring 21 is located on the outer side of the movable rod. First sliding grooves 19 for cooperating with the connecting rod 23 are provided on both sides of the extension rod 503. Second sliding grooves 24 for cooperating with the connecting rod 23 are provided on both sides of the first fixing rod 501 and the inner side of the second fixing rod 502. A fixing block 4 is fixedly installed on the top of the extension rod 503. The fixing block 4 is rotatably connected to the retractable support leg 3. The retractable support leg 3 consists of a front support leg and a rear support leg. The length of the front support leg is shorter than that of the rear support leg. The solar panel body 1 is in an inclined state. The bottom plate 6 is a circular structure. A plurality of groups of protrusions are provided on the outer side of the bottom plate 6, and a plurality of groups of threaded holes are provided on the protrusions.

[0033] Specifically, the first spring 21 connects the push block 22 and the second fixed rod 502, playing the role of buffering and restoring. When the push block 22 is subjected to external force, the spring can absorb the impact force, avoid rigid collision between components, and reduce the possibility of wear and damage. At the same time, the restoring force of the spring helps the push block 22 to return to its initial position after the external force disappears, ensuring the stability and reliability of the entire mechanism. The first slide 19 is opened on both sides of the extension rod 503, and the second slide 24 is opened on both sides of the first fixed rod 501 and the inner side of the second fixed rod 502, providing space for sliding and rotating of the connecting rod 23, thereby realizing the folding and telescopic function of the mounting frame body 5. The setting of the slide can also guide and constrain the movement of the connecting rod 23. The fixed block 4 is installed on the top of the extension rod 503, so that the support leg can move around the fixed rod 503. The fixed block 4 is rotated to facilitate the folding of the retractable support legs 3, and the retractable support legs 3 are composed of a front support leg and a rear support leg, and the front support leg is shorter than the rear support leg. With this structure, the solar panel body 1 can be in an inclined state, and the inclined solar panel can better receive sunlight, thereby improving the efficiency of solar energy collection. Finally, the bottom plate 6 is a circular structure, which has better stability and balance, can evenly distribute the weight of the solar panel and its accessories, and reduce the pressure concentration on the installation ground. The protrusions on the outer side of the bottom plate 6 and the multiple groups of threaded holes opened on the protrusions are convenient for fixing the bottom plate 6 to different installation surfaces by connecting parts such as bolts, thereby increasing the firmness and reliability of the installation. At the same time, this structure also facilitates installation and disassembly in different occasions, thereby improving the portability and versatility of the device.

[0034] The working principle of the present invention is:

[0035] First, the wind measuring mechanism 11 uses a three-cup anemometer to monitor wind speed and direction in real time, transmitting the data to the data acquisition module in the support frame 10. At the same time, the slider 13 slides in the slide rail 12 due to the centrifugal force generated by the wind speed. Its position information is collected by the sensor 14 and transmitted to the data acquisition module to provide a basis for system decision-making;

[0036] Secondly, the control unit judges based on the information from the data acquisition module that when the wind speed reaches the set threshold, it activates the response mechanism. The motor 17 drives the rotating block 18 and the fixing frame 7 to rotate the solar panel body 1 so that it meets the wind direction. The electric telescopic rod 9 retracts to lower the height of the solar panel to below the baffle 8, reducing wind resistance and enhancing stability.

[0037] It is worth mentioning that the first spring 21 provides a buffer and reset function for the push block 22, protecting the mechanism and maintaining stability; the first slide groove 19 and the second slide groove 24 constrain the movement of the connecting rod 23, ensuring that the mounting frame body 5 can be reliably folded and extended; the fixed block 4 cooperates with the retractable support leg 3 to realize the rotation and folding of the support leg, and the length difference between the front and rear support legs keeps the solar panel body 1 tilted, thereby improving the efficiency of light energy collection;

[0038] Finally, when the wind force decreases, the slider 13 is reset under the action of the second spring 25. After the control system detects the reset signal and the wind speed drops to a safe range, the solar panel automatically returns to its normal working angle and height. The circular base plate 6 distributes the weight with good stability, and its outer protrusions and threaded holes are convenient for fastening to different mounting surfaces through bolts and other connectors. It is also easy to disassemble, thereby improving the portability and versatility of the device.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
