Description

Technical Field

[0001] This application relates to the field of photovoltaic glass dismantling technology, and in particular to a ladder for assisting in the dismantling of rooftop photovoltaic systems. Background Technology

[0002] Currently, a large number of photovoltaic panels are installed on rooftops in rural areas of my country. As their service life gradually increases, more and more photovoltaic panels need to be replaced and dismantled. Considering that the price of damaged photovoltaic panels is significantly lower than that of undamaged photovoltaic panels during recycling, properly dismantling rooftop photovoltaic panels and transferring them intact to the ground has significant economic benefits.

[0003] Existing technologies, such as the utility model with publication number CN118180106A, specifically disclose a photovoltaic module glass panel recycling device, a double-roller conveying mechanism, and a glass crushing and detachment mechanism. The glass crushing and detachment mechanism includes multiple evenly spaced scraper units and a moving structure that enables the scraper units to reciprocate along the width direction of the laminate. The scraper units are located in the forward direction of the laminate and below the glass surface of the laminate. The side of the scraper facing the glass panel has a blade that contacts the glass panel and an arc-shaped surface adjacent to the blade. After the glass panel of the laminate is flattened by the flattening gap between the upper and lower rollers while maintaining a relatively flat posture, the blade of the scraper unit contacts the glass panel. An active space is formed between the arc-shaped surface and the laminate above. The glass panel is crushed by a lateral force and scraped off to form glass fragments that detach from the solar cells of the laminate. The glass particles can be thrown out on both sides of the arc-shaped surface by the reciprocating movement of the scraper units, preventing the accumulation of glass particles.

[0004] The above-mentioned technical content has the following defects: Due to the large weight of the photovoltaic panels, it is difficult to transfer them to the ground. Currently, mechanical equipment is mainly used to transfer them from the roof. However, considering that the distribution of rooftop photovoltaics in rural areas is relatively scattered and the rural roads are relatively narrow, it is not conducive to the construction of mechanical equipment. Therefore, this invention designs a special ladder that can directly transfer the photovoltaic panels from the roof to the ground intact, effectively reducing the damage during transfer and improving the economic benefits of photovoltaic panel recycling. Utility Model Content

[0005] One of the technical problems this application aims to solve is that rooftop photovoltaic systems are scattered in rural areas, and the narrow road space in rural areas makes it difficult for mechanical equipment to carry them out.

[0006] To address the aforementioned technical problems, this application provides a ladder for assisting in the dismantling of rooftop photovoltaic systems, comprising:

[0007] The main frame has several support plates evenly installed on its lower surface. The support plates are divided into two groups and evenly distributed on the two main frames. The two groups of support plates on the two main frames are distributed in a cross pattern.

[0008] The limit buckle is fixedly connected to the main frame and slidably connected to the support plate; and

[0009] Transmission adjustment structure; the transmission adjustment structure is installed on the main frame;

[0010] The transmission adjustment structure includes several positioning holes, which are evenly distributed on the support plate. A pin is slidably inserted into the limit buckle, and the pin is slidably connected to the positioning hole of the limit buckle. Several fixing plates are fixedly connected to the inner side of the main frame. A lead screw is threaded into the fixing plate. One end of the lead screw is rotatably connected to a connecting frame. A rotating shaft is rotatably connected inside the connecting frame. A pulley is fixedly connected to the arc surface of the rotating shaft. A rubber block is fixedly connected to one end of the rotating shaft. Anti-slip textures are evenly distributed on one side of the rubber block.

[0011] The aforementioned components achieve the effect of enabling the rapid removal and transfer of photovoltaic glass from the roof.

[0012] In some embodiments, a groove is provided on the inner side of the main frame corresponding to the position of the connecting frame, and a slider is fixedly connected to the lower surface of the connecting frame, and the slider slides inside the groove of the main frame.

[0013] The effect achieved by the above-mentioned components is to restrict the movement of the connecting frame.

[0014] In some embodiments, the highest point of the pulley is higher than the highest point of the fixed plate.

[0015] In some embodiments, a rubber pad is fixedly connected to one side of the main frame corresponding to the rubber block, and the size of the rubber pad is adapted to the size of the main frame.

[0016] The effect achieved by the above-mentioned components is to increase the friction between the rubber block and the main frame.

[0017] In some embodiments, a number of positioning buckles are fixedly connected to one side of the main frame. The positioning buckles have a "C" shaped cross section and a telescopic rod is provided inside the positioning buckle. A hook is fixedly connected to the output end of the telescopic rod.

[0018] The effect achieved by the above components is that when the photovoltaic glass panel gets stuck while sliding along the pulley, the glass panel can be moved with the help of hooks to assist the glass panel in sliding.

[0019] In some embodiments, a protective sleeve is fixedly connected to the arc surface of the hook, and the protective sleeve is a sponge sleeve.

[0020] The effect achieved by the above-mentioned components is to prevent the hook from hitting the photovoltaic glass panel and causing damage to it.

[0021] In some embodiments, a handle is fixedly connected to the lowest end of the telescopic rod, and the arc surface of the handle is uniformly provided with anti-slip protrusions.

[0022] The effect achieved by the above components is to facilitate the pulling of the telescopic rod to adjust the position of the hook.

[0023] The above technical solutions solve the problem of photovoltaic panels being easily broken when transferred from the roof to the ground, thus improving the economic benefits of photovoltaic panel recycling. They also solve the problem of narrow road space in rural areas, which makes it difficult to use mechanical equipment to transfer photovoltaic panels from the roof to the ground. The equipment is inexpensive, made of readily available materials, has a simple structure that is easy to maintain, and is convenient to transport and use. The equipment occupies little space and has an adjustable width, making it suitable for rural environments and other environments where it is not conducive to the operation of mechanical equipment.

[0039] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a ladder for dismantling rooftop photovoltaic systems, including a main frame 1, with a number of support plates 2 evenly installed on the lower surfaces of the two main frames 1. The support plates 2 are divided into two groups and evenly distributed on the two main frames 1, with the two groups of support plates 2 on the two main frames 1 being cross-distributed.

[0040] Limit buckle 3 is fixedly connected to the main frame 1 and slidably connected to the support plate 2; and

[0041] Transmission adjustment structure 4; transmission adjustment structure 4 is installed on the main frame 1.

[0042] The specific settings and functions of transmission regulation structure 4 will be explained in detail below.

[0043] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the transmission adjustment structure 4 includes several positioning holes 401, which are evenly distributed on the support plate 2. A pin 402 is slidably inserted into the limiting buckle 3, and the pin 402 is slidably connected to the positioning hole 401 of the limiting buckle 3. Several fixing plates 403 are fixedly connected to the inner side of the main frame 1. A lead screw 404 is threaded into the fixing plate 403. One end of the lead screw 404 is rotatably connected to a connecting frame 405. A rotating shaft is rotatably connected inside the connecting frame 405. A pulley 406 is fixedly connected to the arc surface of the rotating shaft. A rubber block 407 is fixedly connected to one end of the rotating shaft. Anti-slip textures are evenly distributed on one side of the rubber block 407. This achieves the effect of quickly transferring photovoltaic glass removed from the roof. A sliding groove 408 is provided on the inner side of the main frame 1 corresponding to the position of the connecting frame 405. A slider 409 is fixedly connected to the lower surface of the connecting frame 405, and the slider 409 slides inside the sliding groove 408 of the main frame 1. This achieves the effect of restricting the movement of the connecting frame 405. The highest point of the pulley 406 is higher than the highest point of the fixed plate 403. A rubber pad 410 is fixedly connected to one side of the main frame 1 corresponding to the rubber block 407, and the size of the rubber pad 410 is adapted to the size of the main frame 1. This achieves the effect of increasing the friction between the rubber block 407 and the main frame 1.

[0044] Several positioning buckles 411 are fixedly connected to one side of the main frame 1. The positioning buckles 411 have a "C" shaped cross-section and a telescopic rod 412 is installed inside each positioning buckle 411. A hook 413 is fixedly connected to the output end of the telescopic rod 412. When the photovoltaic glass panel gets stuck while sliding along the pulley 406, the hook 413 can be used to move the glass panel and assist its sliding. A protective sleeve 414, which is made of sponge, is fixedly connected to the arc surface of the hook 413. This prevents the hook 413 from hitting the photovoltaic glass panel and causing damage. A handle 415 is fixedly connected to the bottom of the telescopic rod 412. The arc surface of the handle 415 is evenly provided with anti-slip protrusions, which facilitates pulling the telescopic rod 412 to adjust the position of the hook 413.

[0045] Working principle: When the photovoltaic glass panels removed from the roof need to be transported to the ground, the lead screw 404 is first rotated, causing the connecting frame 405 to move via the thread. The connecting frame 405 then drives the slider 409 to slide along the inner wall of the groove 408 of the main frame 1. The slider 409 and the groove 408 restrict the movement of the connecting frame 405, thus ensuring that rotating the lead screw 404 can drive the connecting frame 405 to move radially. At this time, the rubber block 407 will be pressed against the rubber pad 410, achieving the effect of adjusting the friction between the connecting frame 405 and the main frame 1. When the pulley 406 rotates, it will drive the rubber block 407 to rotate via the shaft. The rotation of the rubber block 407 will be subject to friction between itself and the rubber pad 410, thereby achieving the effect of adjusting the friction between the connecting frame 405 and the main frame 1. 6. Adjust the tightness of the pulley. When placing the photovoltaic glass panel on the pulley 406, adjust the speed at which the photovoltaic glass panel slides down by adjusting the tightness of the pulley 406. Then pull the pin 402 to slide it out of the limit buckle 3. At this time, pull the two main frames 1 to adjust the distance between the two main frames 1 to match the size of the disassembled photovoltaic glass panel. Then, put the pin 402 back through the limit buckle 3 and insert it into the positioning hole 401 of the support plate 2. Then, place the two main frames 1 on the ground at an angle, with the upper end resting on the roof. First, place a photovoltaic glass panel on the pulley 406 and observe the sliding speed of the photovoltaic glass panel. Adjust the tightness of the pulley 406 by observing the sliding speed of the photovoltaic glass panel. After adjustment, the two operators can start working. First, one operator on the roof places the dismantled photovoltaic glass panel onto pulley 406, which then slides down. Another operator on the ground catches the panel as it falls to the appropriate height, taking care not to let it slide directly to the ground to avoid damaging it. When the photovoltaic glass panel gets stuck on the pulley 406, the operator on the ground can remove the telescopic rod 412 from the positioning buckle 411, adjust the length of the telescopic rod 412, and finally use the hook 413 to pull down the stuck photovoltaic glass panel, assisting the photovoltaic glass panel to slide down. The protective sleeve 414 on the hook 413 can improve the flexibility of the hook 413 surface, thereby avoiding damage to the photovoltaic glass panel. After the hook 413 and telescopic rod 412 are used, the output end of the telescopic rod 412 can be retracted, and then the telescopic rod 412 and hook 413 can be re-locked in the positioning buckle 411. The positioning buckle 411 serves as a temporary storage for the telescopic rod 412.
