They directly generate electricity by absorbing sunlight on the front side and generate auxiliary electricity by using reflected light on the back side, effectively improving energy conversion efficiency. However, in actual application, the back-side power generation efficiency of double-glass photovoltaic modules is greatly affected by factors such as reflection effect, dust accumulation, and angle adaptation.

DETAILED DESCRIPTION
[0032] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.
[0033] As Figure 1 , Figures 3 to 5 , Figures 7 to 9 and Figure 11 : a dustproof structure of a dual-glass photovoltaic module for agro-photovoltaic complementation, comprising a mounting rack 1, a solar panel 111 and a light reflection assembly 121, the mounting rack 1 is provided with a supporting rack 13 and a first rotating shaft 11 and a second rotating shaft 12 extending in parallel along the horizontal direction; one end of the solar panel 111 is sleeved on the first rotating shaft 11, and the other end of the solar panel 111 is placed on the supporting rack 13, so that the solar panel 111 is arranged in an inclined posture on the mounting rack 1; the light reflection assembly 121 is located below the solar panel 111, and the light reflection assembly 121 comprises a supporting frame 1211 and a plurality of light reflection strips 12111; the supporting frame 1211 is sleeved on the second rotating shaft 12, when the supporting frame 1211 rotates around the second rotating shaft 12 towards the solar panel 111, the supporting frame 1211 abuts against the solar panel 111 and pushes the solar panel 111 to rotate around the first rotating shaft 11 so that the dust on the surface of the solar panel 111 slides off; the supporting frame 1211 is provided with supporting shafts 12112 which are the same in number as the light reflection strips 12111 and correspond to the light reflection strips 12111 one by one; the plurality of light reflection strips 12111 are respectively connected to the plurality of supporting shafts 12112, and the light reflection strips 12111 turn over by rotating around the supporting shafts 12112 to remove the dust on their surfaces by gravity.
[0034] During daily operation of the equipment, the supporting frame 1211 of the light reflection assembly 121 rotates around the second rotating shaft 12 to adjust the angle of the light reflection assembly 121, and the rotation of the plurality of light reflection strips 12111 around the corresponding supporting shafts 12112 forms multi-level angle adjustment, the overall rotation of the supporting frame 1211 adapts to large range angle changes of sunlight, and the individual rotation of the light reflection strips 12111 can finely adjust local light differences, so that the reflected light is more accurately projected onto the back of the solar panel 111, and the light energy utilization efficiency of the back of the solar panel 111 is improved.
[0035] When it is necessary to clean the dust on the surfaces of the solar panel 111 and the light reflection assembly 121, the supporting frame 1211 moves around the second rotating shaft 12 towards the solar panel 111 until the supporting frame 1211 abuts against the back of the solar panel 111, and through continuous rotation of the supporting frame 1211, the supporting frame 1211 pushes the solar panel 111 to rotate synchronously around the first rotating shaft 11, so that the angle of the originally inclined solar panel 111 increases, and the dust adhered to the surface slides off along the panel under the action of gravity; at the same time, the light reflection strips 12111 turn over by rotating around the supporting shafts 12112 to turn the dust accumulation surface downward, and the dust on the light reflection strips 12111 also falls off naturally by gravity, thereby completing synchronous cleaning of the dust on the surfaces of the solar panel 111 and the light reflection assembly 121.
[0036] The multi-level angle adjustment of the light reflection assembly 121 enhances the light reflection performance. The movement of the light reflection assembly 121 is combined with the cleaning action of the solar panel 111 through mechanical linkage, so that self-cleaning can be achieved without additional driving components, and the structure is simple and suitable for the complex environment of the agricultural photovoltaic complementary scene. The cooperation of the light reflection strip 12111 and the support shaft 12112 not only improves the adjustment accuracy of the light reflection angle, but also solves the problem of difficult cleaning of traditional light reflection plates.
[0037] As shown in Figures 1 to 7 The solar panel 111 is provided with a cleaning assembly 14, which includes a roller brush 141 and two sliding racks 142. The two sliding racks 142 are respectively located on the two sides of the solar panel 111, and the roller brush 141 is rotatably arranged between the two sliding racks 142. The top and bottom of each sliding rack 142 is provided with a pulley set 1421.
[0038] The sliding rack 142 forms a clamping structure for the solar panel 111 through the pulley sets 1421 arranged at the top and bottom thereof. The distance between the two pulley sets 1421 matches the thickness of the solar panel 111, which can be stably clamped to the two side edges of the solar panel 111, ensuring that the sliding rack 142 does not deviate from the panel surface and always maintains a vertical posture with the panel surface. The roller brush 141 is rotatably connected between the two sliding racks 142, and the distance between the two sliding racks 142 matches the width of the solar panel 111, so that the roller brush 141 just covers the surface of the solar panel 111; at the same time, the two sliding racks 142 also form a clamping structure for the solar panel 111.
[0039] When the sliding rack 142 slides along the length direction of the solar panel 111, the roller brush 141 rolls in contact with the surface of the solar panel 111, and the dust on the surface is removed through the physical friction of the bristles. The rolling arrangement of the pulley set 1421 reduces the sliding resistance, allowing the sliding rack 142 to move smoothly under the action of a small external force, while allowing the roller brush 141 to automatically adjust the contact posture according to the slight unevenness of the panel surface, adapting to solar panels 111 of different manufacturing accuracy. The symmetrical layout of the double-sided sliding rack 142 balances the stress on the roller brush 141, avoiding shaking or deviation caused by uneven stress on one side, ensuring uniformity of cleaning effect, reducing local wear and tear, and prolonging the service life of the assembly.
[0040] As shown in Figures 1 to 7 The top end of the solar panel 111 is provided with a winding shaft 143, and the steel wire rope 1431 is connected between the winding shaft 143 and the sliding rack 142. In the initial state, the sliding rack 142 is located at the top of the solar panel 111. When the solar panel 111 is lifted around the first rotating shaft 11, the sliding rack 142 slides down along the solar panel 111 under the action of gravity and pulls out the steel wire rope 1431 from the winding shaft 143.
[0041] Initially, the carriage 142 and roller brush 141 rest on top of the solar panel 111, with the wire rope 1431 on the reel 143 in a reeled position, securing the carriage 142 at the top. As the solar panel 111 is raised about the first rotation axis 11 to adjust its angle, its surface forms a downward slope. Under the weight of the carriage 142 and the roller brush 141, the carriage 142 slides down the slope, simultaneously pulling the attached wire rope 1431 from the reel 143. This causes the reel 143 to release the wire rope 1431 in sync with the movement of the carriage 142. During this process, the descent of the carriage 142 coordinates with the lifting of the solar panel 111, allowing the roller brush 141 to naturally move along the length of the solar panel 111 under gravity, completing the surface cleaning. By organically combining the cleaning action with the angle adjustment of the solar panel 111, there is no need to set up an additional independent driving mechanism. The automatic sliding cleaning of the roller brush 141 can be achieved only by the linkage of gravity and structure, which simplifies the system structure and reduces energy consumption; the cooperation between the winding shaft 143 and the wire rope 1431 not only plays the role of initially fixing the sliding frame 142, but also can smoothly release the stroke when the sliding frame 142 slides down, avoiding jamming or offset during the sliding process; at the same time, the sliding stroke of the sliding frame 142 is adaptively adjusted with the lifting angle of the solar panel 111, ensuring that the surface of the solar panel 111 can be covered under different tilt states, thereby improving the comprehensiveness and reliability of cleaning, and is especially suitable for the use needs of the solar panel 111 in the agricultural and photovoltaic complementary scenario where the angle needs to be frequently adjusted.
[0042] like Figures 1 to 7 As shown, a first gear 1432 is sleeved around the end of the winding shaft 143, and a second gear 15 meshing with the first gear 1432 and a first rotation driving motor 151 for driving the second gear 15 to rotate are provided on the support bracket 13.
[0043] After the solar panel 111 is adjusted in angle so that the roller brush 141 slides to its bottom, the solar panel 111 is reset, the first gear 1432 on the winding shaft 143 is engaged with the second gear 15, the first rotary drive motor 151 is started, and the output shaft of the first rotary drive motor 151 drives the second gear 15 to rotate. The rotation of the second gear 15 drives the first gear 1432 engaged with it to rotate synchronously, thereby driving the winding shaft 143 to reel in, and pulling the sliding frame 142 and the roller brush 141 back to the initial position at the top of the solar panel 111.
[0044] The meshing of the first gear 1432 and the second gear 15 ensures the accuracy and stability of the reset action of the rolling brush 141, avoids the slack or winding of the steel wire rope 1431 during the winding process, and enables the sliding frame 142 to smoothly return along the surface of the solar panel 111, thereby preparing for the next cleaning cycle. Meanwhile, the first rotary drive motor 151 drives the reset action of the solar panel 111, and the cycle operation of the cleaning assembly 14 can be completed without manual intervention, which greatly reduces the operation and maintenance cost in the agricultural and solar complementary scene. The transmission structure characteristics of the first gear 1432 and the second gear 15 also ensure the efficiency of power transmission, so that the rolling brush 141 can be reliably reset in different environments even after long-term use, adapt to the frequent angle adjustment requirements of the solar panel 111, and prolong the service life of the cleaning assembly 14.
[0045] As shown in Figures 3 to 9 The plurality of support shafts 12112 on the support frame 1211 are provided with a synchronous belt 12113, one side of one of the support shafts 12112 is provided with a driving shaft 1212, the support shaft 12112 and the driving shaft 1212 are respectively sleeved with a first bevel gear 12114 and a second bevel gear 12121, and the first bevel gear 12114 and the second bevel gear 12121 are meshed and connected, and the support frame 1211 is provided with a second rotary drive motor 12122 for driving the driving shaft 1212 to rotate.
[0046] When the second rotary drive motor 12122 is started, the output shaft of the second rotary drive motor 12122 drives the driving shaft 1212 to rotate, so that the second bevel gear 12121 fixed on the driving shaft 1212 rotates and meshes with the first bevel gear 12114 on the support shaft 12112, and the driving force is transmitted to the support shaft 12112; since the plurality of support shafts 12112 are connected by the synchronous belt 12113, the rotation of the first support shaft 12112 drives the remaining support shafts 12112 to rotate synchronously through the synchronous belt 12113, so that all the reflective strips 12111 rotate synchronously around the respective support shafts 12112. Through the arrangement of the plurality of synchronous belts 12113, the consistency of the action of the plurality of reflective strips 12111 is ensured, so that all the reflective strips 12111 can complete the turning over at the same angle and speed, which not only ensures the uniformity of the reflected light, but also synchronously turns the accumulated dust downward during cleaning. The above-mentioned mode improves the adjustment accuracy and reliability of the reflective assembly 121, so that the reflective strips 12111 can maintain positioning accuracy at different angles, adapt to the dynamic change of the light angle, and reduce the operation and maintenance difficulty in the agricultural and solar complementary scene; the synchronous turning over function driven by the second rotary drive motor 12122 enables the reflective strips 12111 to be quickly adjusted to the optimal reflection angle or cleaning posture as needed, which improves the power generation efficiency and effectively solves the problem of decreased reflectivity after dust accumulation of the traditional reflective device.
[0047] As shown in Figures 3 to 9 : the two sides of the support frame 1211 are provided with connecting rods 1213 hinged thereto, the mounting frame 1 is provided with a sliding block 1214 sliding along the length direction thereof, and the other end of the connecting rod 1213 is hinged to the sliding block 1214.
[0048] When the sliding block 1214 slides along the length direction of the mounting frame 1, the connecting rod 1213 pushes or pulls the support frame 1211 due to the change of the position of the two hinged points, so that the support frame 1211 is adjusted in angle around the second rotating shaft 12. The sliding direction of the sliding block 1214 determines the rotating direction of the support frame 1211, when the sliding block 1214 moves towards the second rotating shaft 12, the connecting rod 1213 pushes the support frame 1211 to rotate upwards to approach the solar panel 111; when the sliding block 1214 moves away from the second rotating shaft 12, the connecting rod 1213 pulls the support frame 1211 to rotate downwards to move away from the solar panel 111, and the whole process realizes stable adjustment of the angle of the support frame 1211 through the rigid linkage of the mechanical structure.
[0049] The advantage of this adjustment is that through the cooperation of the bilaterally symmetric distributed connecting rods 1213 and the sliding block 1214, balanced support force is provided for the support frame 1211, avoiding the inclination or deformation caused by unilateral force, and enhancing the structural stability of the reflecting assembly 121 in the rotating process; the sliding of the sliding block 1214 along the length direction of the mounting frame 1 provides linear guidance for the angle adjustment of the support frame 1211, making the angle change more stable and controllable, and facilitating the accurate adjustment of the relative position between the reflecting assembly 121 and the solar panel 111; at the same time, the adoption of the hinged structure makes the movement between the connecting rod 1213, the sliding block 1214 and the support frame 1211 more flexible, reduces the mechanical wear, prolongs the service life of the components, and the overall structure is simple, without the need for complex transmission components, which meets the needs of reliability and maintenance convenience of the equipment in the agricultural and photovoltaic complementary scene.
[0050] As shown in Figures 3 to 9 : the mounting frame 1 is further provided with a lead screw 12141 extending along the length direction thereof, the sliding block 1214 is sleeved on the lead screw 12141 and threadedly cooperates with the lead screw 12141, and the mounting frame 1 is provided with a third rotating drive motor 12142 for driving the lead screw 12141 to rotate.
[0051] When the third rotary drive motor 12142 is started, the third rotary drive motor 12142 output shaft drives the screw rod 12141 to rotate around its own axis, so that the sliding block 1214 sleeved on the screw rod 12141 moves linearly along the length direction of the mounting frame 1 under the rotation of the screw rod 12141 due to the threaded cooperation. The movement of the sliding block 1214 drives the connecting rod 1213 to move, and the connecting rod 1213 pushes or pulls the support frame 1211 to rotate around the second rotation shaft 12, so as to realize the precise adjustment of the rotation angle of the support frame 1211.
[0052] The self-locking characteristic of the screw rod 12141 transmission can automatically lock the position of the sliding block 1214 when the third rotary drive motor 12142 stops rotating, which ensures that the support frame 1211 remains stable at the set angle and avoids angle deviation caused by external interference such as wind force, thereby improving the reliability of the equipment. This compact and stable transmission structure not only meets the demand for frequent adjustment of the reflector assembly 121 in the agricultural light complementary scene, but also reduces the maintenance cost and prolongs the service life of the equipment.
[0053] As shown in Figure 3 , Figure 7 , Figure 8 and Figure 10 , the top of the support frame 1211 is provided with a support strip 12115 made of elastic material, and the back of the solar panel 111 is provided with a butt joint plate 1111 matched with the support strip 12115.
[0054] When the support frame 1211 rotates around the second rotation shaft 12 towards the solar panel 111 and gradually approaches, the elastic support strip 12115 at the top of the support frame 1211 first contacts the butt joint plate 1111 on the back of the solar panel 111. As the support frame 1211 continues to rotate, the support strip 12115 deforms due to its elastic material properties, absorbing the impact force when the two contact, avoiding damage to the solar panel 111 or the support frame 1211 caused by rigid collision. In this contact mode, the butt joint plate 1111 provides a flat contact surface for the support strip 12115, ensuring that the deformation of the support strip 12115 is uniform and the stress is balanced, which not only ensures the effective pushing of the support frame 1211 to the solar panel 111, but also eliminates the stress concentration caused by the instantaneous impact force through elastic buffering.
[0055] Through the cooperation of the elastic support strip 12115 and the butt joint plate 1111, the possible wear or cracking of the back of the solar panel 111 caused by direct contact of metal parts is avoided in structure, especially protecting the fragile areas of the edges and back of the solar panel 111.
[0056] As shown in Figures 1 to 7 , a sensor for detecting the intensity of ambient light is also arranged on the mounting frame 1.
[0057] A sensor (not shown in the figure) can continuously detect the light intensity and incident angle of the surrounding environment, and transmit the real-time collected light information to the control system. When it is detected that the light intensity exceeds a preset threshold or the incident angle may cause excessive light exposure to a local area of the solar panel 111, the angle adjustment mechanism of the reflective component 121 and the solar panel 111 is triggered through the back-end control system; through the coordination of the sensor and the control system, the angle adjustment accuracy of the reflective component 121 is improved, ensuring that the reflected light is continuously and efficiently utilized by the solar panel 111, reducing the waste of light energy; at the same time, precise angle control avoids the ineffective irradiation of the edge or non-light-receiving area of the solar panel 111 by the reflected light of the reflective strip 12111 due to angle deviation.
