Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation equipment technology, and in particular to a photovoltaic panel bracket with height adaptive adjustment function. Background Technology

[0002] With the rapid development of renewable energy, photovoltaic (PV) power generation, as a clean and efficient energy utilization method, has been widely applied. As the core component of a PV power generation system, the performance of its installation and support structure directly affects power generation efficiency and system stability. In practical applications, PV panels typically need to be installed on brackets, and their angle and height need to be adjusted to adapt to different lighting conditions and terrain environments to improve power generation efficiency. However, existing PV panel brackets have significant shortcomings in height adjustment.

[0003] Most photovoltaic panel brackets on the market currently adopt a fixed or manually adjustable design. These brackets often struggle to achieve quick and precise height adjustments when facing complex terrain or seasonal changes in sunlight. Furthermore, while some brackets do offer some adjustment capabilities, their operation is cumbersome and requires manual intervention, increasing maintenance costs and reducing system reliability and adaptability. The limitations of existing brackets are particularly pronounced in scenarios involving sloping terrain, uneven ground, or frequent height adjustments.

[0004] Therefore, developing a photovoltaic panel bracket with height adaptive adjustment function, capable of automatically adjusting its height according to terrain changes and installation requirements, can not only improve the installation efficiency and applicability of photovoltaic panels but also optimize the overall performance of the photovoltaic power generation system. This bracket design will significantly improve existing problems and provide strong support for the efficient operation of photovoltaic power generation systems. Utility Model Content

[0005] The purpose of this utility model is to provide a photovoltaic panel bracket with height adaptive adjustment function, which solves the problems mentioned in the background art.

[0006] This utility model is implemented as follows: a photovoltaic panel bracket with height adaptive adjustment function includes a base, a drive housing is provided on one side of the top of the base, and further includes:

[0007] The support frame has an open structure at the top and bottom. A column is fixedly installed on the other side of the top of the base. A guide rail is fixed between the drive box and the column at intervals. The support frame is located between the guide rails. The output end of the drive box is a screw structure connected to the support frame. The drive box is used to drive the support frame to move up and down along the guide rails through the screw structure. An inclined mounting plate is fixedly connected to the base. The mounting plate is located at the bottom of the support frame.

[0008] An adjustment assembly is located within a support frame. The adjustment assembly includes a screw rotatably mounted within the support frame, with multiple evenly arranged positioning holes on the screw. The adjustment assembly also includes two arc-shaped limiting blocks and two inclined limiting blocks. The two arc-shaped limiting blocks are spaced apart along the axial direction of the screw and fixedly connected to the inner walls of both sides of the support frame. The two inclined limiting blocks are spaced apart along the radial direction of the screw and fixedly connected to the inner walls of both sides of the support frame. The height of both the arc-shaped and inclined limiting blocks is greater than the height of the screw axis. Both the arc-shaped and inclined limiting blocks mate with the surface of the screw. The arc-shaped limiting blocks, inclined limiting blocks, the top surface of the screw, and the inner wall of the support frame constitute an adjustment cavity.

[0009] Both sides of the support frame are provided with main sliders that cooperate with two guide rails. The main sliders are provided with gear structures with directional rotation function. The main sliders and the screw are connected by a transmission device fixedly set on the outer surface of the support frame.

[0010] Preferably, a sub-frame is fixedly connected to the side of the support frame away from the drive housing, and sub-sliders that cooperate with the guide rail are rotatably arranged on both sides of the sub-frame. The sub-frame, sub-sliders, main sliders and screw are all in the same plane.

[0011] Preferably, a rectangular groove is provided at the joint between the support frame and the sub-frame. A vertically arranged guide rod is fixedly connected inside the sub-frame. A horizontally arranged connecting rod is slidably connected to the guide rod. A strip block is fixedly connected to one end of the connecting rod facing the rectangular groove. A cleaning plate is provided on the strip block. A double-end arm is connected to the other end of the connecting rod. Both ends of the double-end arm are fixedly connected to pins. Turntables connected to the sub-slider are provided on both sides inside the sub-frame. Elliptical holes that cooperate with the pins are provided on the turntables. When the support frame moves up and down, the cleaning plate at one end of the connecting rod moves back and forth through the cooperation of the turntable and the pin, so that it contacts the surface of the screw.

[0012] Preferably, an elastic layer is fixedly connected to the connecting rod, and the elastic layer is sealed to the inner wall of the sub-frame. The elastic layer is located between the guide rod and the strip block, and the elastic layer isolates the internal space of the sub-frame into a closed chamber. The double-end arm and the turntable are both located in the closed chamber.

[0013] Preferably, channels are provided inside the strip block and the connecting rod, and multiple through holes are provided on one side of the cleaning plate on the strip block. An exhaust pipe connected to the channel is fixedly connected to the double-end arm. An air inlet pipe is fixedly provided on the top of the sub-frame. A one-way valve is provided on both the exhaust pipe and the air inlet pipe. A filter cover is fixedly connected to the top of the air inlet pipe.

[0014] Preferably, a box is fixedly connected to the side of the support frame opposite to the rectangular groove, a sensor module is installed inside the box, a transparent window is fixedly installed at the joint between the box and the support frame, and electromagnetic clutches for connecting the secondary slider and the turntable are fixedly connected to both sides of the sub-frame.

[0015] Preferably, one side of the adjustment cavity in the support frame is provided with an inspection door that can be closed or opened.

[0016] The driving method of this device is the same as that of conventional photovoltaic panel brackets. It uses a drive housing and a lead screw structure to move the support frame up and down to adjust the height of the photovoltaic panel. The unique feature is that, by utilizing the up-and-down movement of the support frame, combined with a conventional transmission mechanism and gear structure on the main slider, the screw within the support frame can rotate slowly. This slow rotation of the screw not only allows for switching between the positioning hole areas, but also, due to the screw's structural characteristics, makes the height adjustment of the photovoltaic panel more precise and stable. Even if a positioning hole becomes clogged, a new positioning hole area can be switched to handle the adjustment. This rotating adjustment method not only reduces the frequency of screw cleaning but also makes cleaning easier. In summary, this photovoltaic panel bracket, through the cooperation of simple mechanical structures, achieves height adjustment while also featuring low cleaning frequency and simplified cleaning.

[0023] This utility model provides a photovoltaic panel bracket with height adaptive adjustment function, the specific implementation of which is described in conjunction with the appendix. Figure 1 To be continued Figure 4 Detailed explanation provided. See attached document. Figure 1 As shown, the overall structure of the photovoltaic panel bracket includes a base 1, a drive housing 2, a support frame 3, guide rails 5, and a lead screw structure 6, among other main components. The base 1, serving as the foundation of the entire device, is fixed to the ground or mounting platform. The drive housing 2 is mounted on one side of its top, while a column 4 is fixedly connected to the other side. The drive housing 2 and the column 4 are connected via spaced guide rails 5, which provide a guide path for the support frame 3 to move up and down. The support frame 3 is located between the two guide rails 5 and achieves stable sliding through a main slider 12 that cooperates with the guide rails 5. The output end of the drive housing 2 is connected to the support frame 3 via the lead screw structure 6. When the drive housing 2 is activated, the lead screw structure 6 drives the support frame 3 to move up and down along the guide rails 5, thereby achieving the height adjustment function of the photovoltaic panel. In addition, an inclined mounting plate 7 is fixedly connected to the base 1. The mounting plate 7 is located at the bottom of the support frame 3 and is used to assist in the installation and angle adjustment of the photovoltaic panel.

[0024] An adjustment component is installed inside the support frame 3. This component is the core part for achieving highly precise adjustment and cleaning functions. (See attached image) Figure 2As shown, the adjustment assembly includes a screw 8 rotatably mounted within the support frame 3. The screw 8 has multiple evenly arranged positioning holes 9, which are used for precise positioning during height adjustment. The adjustment assembly also includes two arc-shaped limiting blocks 10 and two inclined limiting blocks 11. The arc-shaped limiting blocks 10 are spaced apart along the axial direction of the screw 8 and fixed to the inner walls of both sides of the support frame 3, while the inclined limiting blocks 11 are spaced apart along the radial direction of the screw 8 and similarly fixed to the inner walls of both sides of the support frame 3. The height of both the arc-shaped limiting blocks 10 and the inclined limiting blocks 11 is greater than the height of the screw 8's axis, and both fit into the surface of the screw 8, forming an adjustment cavity. This adjustment cavity design ensures that the screw 8 is constrained by the limiting blocks during rotation, thereby ensuring the stability of its running trajectory. Both sides of the support frame 3 are provided with main sliders 12 that cooperate with the guide rails 5. The main sliders 12 are provided with gear structures 13 with directional rotation function. The main sliders 12 and the screw 8 are connected by a transmission device 14 fixedly set on the outer surface of the support frame 3. When the support frame 3 moves up and down along the guide rails 5, the gear structure 13 on the main sliders 12 transmits the motion to the screw 8 through the transmission device 14, causing it to rotate slowly.

[0025] To further enhance the stability of the device, a sub-frame 15 is fixedly connected to the side of the support frame 3 away from the drive housing 2, as shown in the attached figure. Figure 1 and attached Figure 2 As shown. The sub-frame 15 has rotatably mounted sub-slider 16 on both sides, which cooperate with the guide rail 5. The sub-frame 15, sub-slider 16, main slider 12, and screw 8 are all in the same plane. This design effectively improves the overall structural balance and anti-overturning ability. A rectangular groove 17 is provided at the joint between the support frame 3 and the sub-frame 15. A vertically mounted guide rod 18 is fixedly connected inside the sub-frame 15, and a horizontally mounted connecting rod 19 is slidably connected to the guide rod 18. A strip block 20 is fixedly connected to one end of the connecting rod 19 facing the rectangular groove 17. A cleaning plate 21 is provided on the strip block 20. A double-ended arm 22 is connected to the other end of the connecting rod 19. Pins 23 are fixedly connected to both ends of the double-ended arm 22. Turntables 24, which are connected to the sub-slider 16, are provided on both sides inside the sub-frame 15. Elliptical holes 25 that cooperate with the pins 23 are provided on the turntables 24. When the support frame 3 moves up and down, the secondary slider 16 drives the turntable 24 to rotate. The turntable 24 pushes the double-end arm 22 to swing back and forth through the cooperation of the elliptical hole 25 and the pin 23, so that the cleaning plate 21 at one end of the connecting rod 19 moves back and forth on the surface of the screw 8, thereby achieving the effect of cleaning the surface of the screw 8.

[0026] To ensure high efficiency in the cleaning process, an elastic layer 26 is fixedly connected to the connecting rod 19. The elastic layer 26 is sealed to the inner wall of the sub-frame 15, isolating the internal space of the sub-frame 15 into a closed chamber. The double-end arm 22 and the turntable 24 are both located within the closed chamber. Channels 27 are provided in both the strip block 20 and the connecting rod 19. Multiple through holes are provided on one side of the cleaning plate 21 on the strip block 20. An exhaust pipe 28 connected to the channel 27 is fixedly connected to the double-end arm 22. An air inlet pipe 29 is fixedly installed on the top of the sub-frame 15. One-way valves are provided on both the exhaust pipe 28 and the air inlet pipe 29. A filter cover 30 is fixedly connected to the top of the air inlet pipe 29. When the cleaning plate 21 moves on the surface of the screw 8, the elastic layer 26 deforms with the movement of the connecting rod 19, thereby changing the volume of the closed chamber, causing gas to enter through the air inlet pipe 29 and exit through the exhaust pipe 28, forming an airflow circulation. This airflow circulation not only removes dust and impurities generated during the cleaning process, but also purifies the incoming air through the filter hood 30, thereby preventing external pollutants from entering the enclosed chamber.

[0027] To achieve intelligent control, a housing 31 is fixedly connected to the side of the support frame 3 opposite to the rectangular groove 17. A sensor module 32 is installed inside the housing 31. A transparent window 33 is fixedly installed at the joint between the housing 31 and the support frame 3, facilitating the sensor module 32 to monitor the operating status of the screw 8. Electromagnetic clutches 34 are fixedly connected to both sides of the sub-frame 15 to drive the sub-slider 16 and the turntable 24. The electromagnetic clutches 34 can control the power transmission between the sub-slider 16 and the turntable 24 according to actual needs, thereby flexibly adjusting the working mode of the cleaning plate 21. Furthermore, a maintenance door 35 that can be closed or opened is provided on one side of the adjustment cavity in the support frame 3. The design of the maintenance door 35 facilitates maintenance and repair of the adjustment components by operators.

[0028] The actual operating principle of this device is as follows: When the height of the photovoltaic panel needs to be adjusted, the drive housing 2 starts and pushes the support frame 3 up and down along the guide rail 5 through the lead screw structure 6. During this process, the gear structure 13 on the main slider 12 transmits the motion to the screw 8 through the transmission device 14, causing the screw 8 to rotate slowly. The rotation of the screw 8 realizes the switching of the positioning hole 9 area on the one hand, and on the other hand, due to the structural characteristics of the screw 8 itself, the height adjustment is more precise and stable. When a positioning hole 9 on the screw 8 becomes blocked due to long-term use, it can be switched to a new positioning hole 9 area by rotation to continue working, thereby reducing the cleaning frequency. At the same time, the auxiliary slider 16 drives the turntable 24 to rotate. The turntable 24 drives the double-end arm 22 to swing back and forth through the cooperation of the elliptical hole 25 and the pin 23, thereby driving the cleaning plate 21 on the connecting rod 19 to clean the surface of the screw 8. During the cleaning process, the deformation of the elastic layer 26 forms airflow circulation, further improving the cleaning effect. The sensor module 32 monitors the operating status of the screw 8 in real time and controls the start and stop of the electromagnetic clutch 34 according to the feedback information to optimize the cleaning frequency and efficiency. Through the close cooperation between the above-mentioned mechanical structures, this device not only achieves height adaptive adjustment function, but also has the characteristics of low cleaning frequency and simple cleaning, making it suitable for various complex environmental scenarios of photovoltaic power generation systems.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
