Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel support technology, specifically an adjustable support for supporting photovoltaic panels. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that uses semiconductor materials to convert light energy into direct current. Its core principle is based on the photovoltaic effect. It achieves stable power generation through a solid structure without moving parts and is suitable for powering small electronic devices. PV panels are often installed on building surfaces, such as roofs, windows, and open outdoor areas, and are used in conjunction with inverters, controllers, and other equipment to form a complete power generation system.

[0003] Currently, photovoltaic (PV) panels require support brackets for installation. These brackets not only support the panels but also provide protection. With the long-term use of PV panels, the brackets have undergone technological improvements to address various daily defects, such as the development of brackets capable of cleaning PV panels in desert environments. However, PV panels installed on residential buildings using brackets still have significant drawbacks, such as:

[0004] 1. Currently, some families install large-area photovoltaic panels on the roof of their buildings using brackets. In order to improve heat absorption efficiency and reduce reflection, photovoltaic panels are usually painted in dark colors. This means that while the photovoltaic panels generate electricity, they also absorb a lot of heat. The heat absorbed by a large number of photovoltaic panels at the same time will be directly transferred to the top of the building. Building materials will age faster in a high-temperature environment for a long time, leading to wall cracks and affecting the interior living conditions.

[0005] 2. Existing photovoltaic panels are usually fixed to the brackets using bolt assemblies. However, in heavy rain and windy weather, the high roof of the building can cause gaps to appear between the photovoltaic panels and the brackets due to strong winds, resulting in loosening. Rainwater contains a large number of metal elements, and prolonged exposure can cause the photovoltaic panels and loose areas to rust and corrode.

[0006] Therefore, an adjustable bracket for supporting photovoltaic panels has been designed to improve heat insulation and protection, thus addressing these shortcomings. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an adjustable support for photovoltaic panels, solving the problem that existing photovoltaic panel support structures are too simple and unsuitable for various environments.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an adjustable support for photovoltaic panels, comprising several sets of protective shower mechanisms and photovoltaic panel installation mechanisms. The protective shower mechanism includes a base support frame, with several base support frames arranged sequentially from front to back. A rectangular protective frame is fixedly installed on the top of each base support frame, and several rectangular protective frames are arranged horizontally. A collection and cleaning groove is provided on the top of each rectangular protective frame, and a mesh filter groove communicating with the collection and cleaning groove is provided on the surface of the rectangular protective frame. Liquid passage grooves communicating with the collection and cleaning groove are provided on both sides of the surface of the rectangular protective frame.

The photovoltaic panel installation mechanism includes a horizontal connecting top plate, and the horizontal connecting top plate is fixedly installed at the rear end of the same set of second electric telescopic rods.

[0009] Preferably, the bottom of the inner cavity of the storage and cleaning trough is provided with a drainage bottom groove extending to the outside.

Both sides of the surface of the base support frame are fixedly installed with first electric telescopic rods, and the opposite ends of two first electric telescopic rods are fixedly connected to the upper curved frame and the lower curved frame, respectively.

[0010] Preferably, a strip-shaped pressure groove is provided at the rear of the inner cavity of the storage and cleaning trough. A sliding tube is slidably installed at the bottom of the inner cavity of the strip-shaped pressure groove through an opening. A U-shaped bracket is fixedly installed at the rear of the rectangular protective frame through a fixing block. A vertical guide rod is fixedly connected to the top of the U-shaped bracket, and the vertical guide rod is slidably installed on the inner side of the sliding tube. A spring is sleeved on the surface of the vertical guide rod between the U-shaped bracket and the sliding tube.

[0011] Preferably, a water storage tank is fixedly installed on the upper part of the inner side of the mesh filter tank by a bracket. A cross valve spray pipe is fixedly connected to the bottom of the water storage tank through an opening. Several cross valve spray pipes are arranged horizontally at equal intervals. The bottom end of the cross valve spray pipe passes through the mesh filter tank and extends to the inner side of the collection and cleaning tank. A water filter box is fixedly installed on the top of the water storage tank through an opening. An activated carbon filter plate is installed on the inner side of the water filter box.

[0012] Preferably, both sides of the rectangular protective frame are fixedly connected to bidirectional air cylinders via brackets, and the air outlets of the bidirectional air cylinders are fixedly connected to air supply pipes. The ends of the air supply pipes on both sides away from the bidirectional air cylinders pass through the water storage cylinder and extend to the inside of the water storage cylinder.

[0013] Preferably, the bottom of the horizontal top plate is fixedly installed with a sealing plate that works in conjunction with the storage and cleaning slot via a fixing block, and the number of sealing plates is the same as that of the rectangular protective frame. The surface of the sealing plate is fixedly connected with a positioning frame that works in conjunction with the storage and cleaning slot, and the photovoltaic panel body is fixedly installed on the inner side of the positioning frame.

[0014] Preferably, both sides of the positioning frame are rotatably connected to rollers that cooperate with the scraper through bearing components, and several rollers are provided. The bottom of the horizontal connecting top plate and both sides of each positioning frame are fixedly connected to U-shaped tension plates through fixing blocks, and the bottom of the U-shaped tension plates is slidably connected to the surface of the bidirectional air cylinder.

[0015] Preferably, an upper retraction groove is provided on the upper side of the surface of the positioning frame, and a lower retraction groove is provided on the upper side of the rear part of the positioning frame. A positioning slide post is slidably installed at the bottom of the inner cavity of the upper retraction groove through an opening, and the bottom end of the positioning slide post extends to the inner side of the lower retraction groove.

[0016] Preferably, a water sealing plate is fixedly connected to one end of the positioning slide column located inside the upper retraction groove, and a water blocking groove is opened on the surface of the water sealing plate to cooperate with the cross valve spray pipe. A pressure bearing horizontal plate is fixedly connected to one end of the positioning slide column located inside the lower retraction groove.

[0017] This invention provides an adjustable support for photovoltaic panels. Compared with existing technologies, it has the following advantages:

[0018] (1) The adjustable bracket for supporting photovoltaic panels combines the protective shower mechanism and the photovoltaic panel installation mechanism. The structure allows for the overlapping installation of several sets of rectangular protective frames and positioning frames. This enables secondary heat insulation during daily use, preventing the building roof from bearing excessive heat. In severe weather, several positioning frames can be retracted to the inside of the storage and cleaning trough via the second electric telescopic rod, and the rectangular protective frames can be used for protection. This not only prevents damage to the photovoltaic panel body from strong winds and hail, but also cleans the photovoltaic panel body. Furthermore, it can provide secondary showering to the photovoltaic panel body during subsequent lifting, thereby improving the stability of the photovoltaic panel body when used on the roof of the building.

[0019] (2) The adjustable bracket for supporting photovoltaic panels can be installed by overlapping the rectangular guard frame and the positioning frame. After the positioning frame is raised and unfolded, the rectangular guard frame can be located at the bottom of the positioning frame, so that when the photovoltaic panel body generates photovoltaic power, it can effectively insulate the temperature and avoid the high temperature from acting directly on the top of the building, thus reducing the damage to the building. After the positioning frame is retracted into the storage and cleaning groove, the mesh filter groove at the rear can be exposed to the outside, thus facilitating rainwater rinsing.

[0020] (3) The adjustable bracket for supporting photovoltaic panels is equipped with a water storage tank and a cross valve spray pipe installed on the top of the mesh filter tank, and is used in conjunction with a two-way air cylinder and a U-shaped tension plate. The structure allows the water sealing plate on the top of the arc-shaped strip to connect and seal the bottom end of the water blocking tank with the bottom end of the cross valve spray pipe when the positioning frame descends into the storage and cleaning tank. This allows the activated carbon filter plate to filter rainwater and store it inside the water storage tank. The rectangular protective frame can protect the photovoltaic panel body and the positioning frame, preventing damage to the photovoltaic panel body from hail and strong winds. When the positioning frame rises and resets, the water sealing plate can be separated from the cross valve spray pipe first, and then the power of the two-way air cylinder is pulled by the U-shaped tension plate to pressurize the inside of the water storage tank, so that the filtered water is sprayed out to rinse the surface of the photovoltaic panel body, preventing residual metal elements in the rainwater from corroding the photovoltaic panel body.

[0021] (4) The adjustable bracket for supporting photovoltaic panels is equipped with a scraper inside the cleaning tank and is used in conjunction with a roller. The structure allows the scraper to brush the surface of the photovoltaic panel by driving the strip plate. The roller can press and soften the scraper when the positioning frame descends, and squeeze the scraper again when it rises to squeeze out excess water, which effectively improves the overall practicality of the equipment.

[0042] Please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 Figure 13 The structure of the protective shower mechanism 1 is shown. The protective shower mechanism 1 includes a base support frame 101, and several base support frames 101 are arranged from front to back. A rectangular guard frame 102 is fixedly installed on the top of the base support frame 101, and several rectangular guard frames 102 are arranged horizontally. A collection and cleaning groove 103 is opened on the top of the rectangular guard frame 102. A mesh filter groove 104 communicating with the collection and cleaning groove 103 is opened on the surface of the rectangular guard frame 102. Liquid passage grooves 105 communicating with the collection and cleaning groove 103 are opened on both sides of the surface of the rectangular guard frame 102. A second electric telescopic rod 121 is fixedly connected to both sides of the surface of the base support frame 101 through openings. The photovoltaic panel installation mechanism 2 includes a horizontal connecting top plate 201, and the horizontal connecting top plate 201 is fixedly installed at the rear end of the second electric telescopic rod 121 in the same group.

[0043] The bottom of the inner cavity of the storage and cleaning trough 103 is provided with a drainage trough 122 extending to the outside. Strip plates 106 are provided on both sides of the inner cavity of the storage and cleaning trough 103. A scraper 123, made of polyvinyl alcohol, is fixedly connected to the bottom of the strip plate 106. The bottom end of the strip plate 106 passes through the drainage trough 122 and extends to the bottom of the rectangular guard frame 102. An upward-curved frame 107 is fixedly connected to the bottom end of several left-side strip plates 106, and a downward-curved frame 108 is fixedly connected to the bottom end of several right-side strip plates 106. First electric telescopic rods are fixedly installed on both sides of the surface of the base support frame 101. 109, the two first electric telescopic rods 109 are fixedly connected at opposite ends to the upper curved frame 107 and the lower curved frame 108 respectively. A strip-shaped pressure groove 110 is provided at the rear of the inner cavity of the storage and cleaning groove 103. A sliding tube 111 is slidably installed at the bottom of the inner cavity of the strip-shaped pressure groove 110 through an opening. A U-shaped bracket 124 is fixedly installed at the rear of the rectangular guard frame 102 through a fixing block. A vertical guide rod 113 is fixedly connected to the top of the U-shaped bracket 124, and the vertical guide rod 113 is slidably installed on the inner side of the sliding tube 111. A spring 114 is sleeved on the surface of the vertical guide rod 113 and between the U-shaped bracket 124 and the sliding tube 111.

[0044] A water storage cylinder 115 is fixedly installed on the upper part of the inner side of the mesh filter tank 104 via a bracket. A cross valve nozzle 116 is fixedly connected to the bottom of the water storage cylinder 115 through an opening. The cross valve nozzle 116 itself has a cross-shaped baffle at its end for water blocking. Internal pressure is required to allow water to spray out through the nozzle. Several cross valve nozzles 116 are arranged horizontally at equal intervals. The bottom end of the cross valve nozzle 116 penetrates the mesh filter tank 104 and extends to the inner side of the collection and cleaning tank 103. The water storage cylinder 11... A water filter box 117 is fixedly installed on the top of the 5 through an opening. An activated carbon filter plate 118 is installed on the inner side of the water filter box 117. Both sides of the rectangular protective frame 102 are fixedly connected to a bidirectional air cylinder 119 through a bracket. The bidirectional air cylinder 119 can be adjusted to supply air and pressurize when pulled. An air supply pipe 120 is fixedly connected to the air outlet of the bidirectional air cylinder 119. The ends of the two air supply pipes 120 away from the bidirectional air cylinder 119 pass through the water storage tank 115 and extend to the inner side of the water storage tank 115.

[0045] Please refer to Figure 14 , Figure 15 , Figure 16 and Figure 17 The overall structure of the photovoltaic panel installation mechanism 2 is shown. The bottom of the horizontal top plate 201 is fixedly installed with a sealing plate 202 that works with the storage and cleaning groove 103 by a fixing block. The number of sealing plates 202 is the same as that of the rectangular guard frame 102. The surface of the sealing plate 202 is fixedly connected with a positioning frame 203 that works with the storage and cleaning groove 103. The photovoltaic panel body 204 is fixedly installed on the inner side of the positioning frame 203.

[0046] Both sides of the positioning frame 203 are rotatably connected to rollers 205 that cooperate with scraper wiper 123 via bearing components, and several rollers 205 are provided. The bottom of the horizontal connecting top plate 201 and both sides of each positioning frame 203 are fixedly connected to U-shaped tension plates 206 via fixing blocks, and the bottom of the U-shaped tension plates 206 is slidably connected to the surface of the bidirectional air cylinder 119.

[0047] The upper side of the positioning frame 203 has an upper retraction groove 207, and the upper side of the rear of the positioning frame 203 has a lower retraction groove 208. The bottom of the inner cavity of the upper retraction groove 207 is slidably installed with a positioning slide post 209 through an opening, and the bottom end of the positioning slide post 209 extends to the inner side of the lower retraction groove 208. The end of the positioning slide post 209 located inside the upper retraction groove 207 is fixedly connected to a water sealing plate 210. The water sealing plate 210 is made of hard rubber, and the surface of the water sealing plate 210 has a water blocking groove 212 for use with the cross valve nozzle 116. The end of the positioning slide post 209 located inside the lower retraction groove 208 is fixedly connected to a pressure-bearing horizontal plate 211.

[0048] In use, the photovoltaic panel body 204 is located inside the positioning frame 203 for photovoltaic power generation. Since several sets of protective shower mechanisms 1 and photovoltaic panel installation mechanisms 2 are installed overlappingly, each rectangular protective frame 102 is located below the front positioning frame 203. When the photovoltaic panel body 204 absorbs heat for photovoltaic power generation, it can be insulated by the rectangular protective frame 102 below. The building roof is subjected to high-temperature erosion for extended periods. In case of severe weather such as rain, snow, hail, or strong winds, the second electric telescopic rod 121 is activated to pull the horizontal connecting roof plate 201 down. The descent of the horizontal connecting roof plate 201 will cause several positioning frames 203 to descend synchronously. During descent, the bottom of the positioning frame 203 will enter the inner side of the collection and cleaning trough 103. The bottom of the positioning frame 203 descends and presses down on the arc-shaped strip 112. Guided by the vertical guide rod 113 and the sliding tube 111, the arc-shaped strip 112 is pressed into the inner side of the strip groove 110 until the positioning frame 203 is fully inserted into the receiving and cleaning groove 103. At this time, the sealing plate 202 seals the top of the receiving and cleaning groove 103. Simultaneously, the lower retraction groove 208 is located at the top of the arc-shaped strip 112. At this time, the arc-shaped strip 112 rises using the elastic force of the spring 114, thereby pushing the pressure plate 211 and the water sealing plate 210 upward, so that the water blocking groove 212 connects with and seals the bottom end of the cross valve nozzle 116. While the positioning frame 203 is lowered and inserted into the receiving and cleaning groove 103, several rollers 20 on both sides... 5 will press the scraper 123 from the bottom, thereby squeezing and softening the scraper 123. The U-shaped pressure plate 206 will first descend a short distance, and when the top of the inner side of the U-shaped pressure plate 206 contacts the top of the bidirectional air cylinder 119, it will press the bidirectional air cylinder 119 to retract. At this time, the positioning frame 203 and the photovoltaic panel body 204 are protected by the rectangular protective frame 102 to prevent hail damage and strong winds from shaking. Rainwater will fall through the mesh filter 104 onto the surface of the photovoltaic panel body 204, washing it. At this time, the two first electric telescopic rods 109 are activated, respectively pushing the upper bending frame 107 and the lower bending frame 108 to move back and forth in opposite directions. The movement is also driven by the strip plate 106, which moves the scraper 123, allowing it to scrub the surface of the photovoltaic panel 204 inside the collection and cleaning trough 103. Rainwater and debris are discharged through the drainage trough 122. Simultaneously, some rainwater enters the filter box 117 and then flows into the water storage tank 115 through the activated carbon filter plate 118. Due to the characteristics of the cross valve nozzle 116 and the blockage of the cross valve nozzle 116 by the water blocking groove 212, the filtered water will not flow out, effectively removing internal metal elements from the rainwater filtered by the activated carbon filter plate 118. After the severe weather, the strip plate 106 drives the scraper 123 to return to its original position on both sides.Then, the second electric telescopic rod 121 is activated to push the horizontal top plate 201, causing several positioning frames 203 to rise and be pulled out from the inside of the collection and cleaning trough 103. During the rising process of the positioning frames 203, they will also rise a short distance first, so that the bottom of the positioning frames 203 will press against the arc-shaped strip 112 again, pressing the arc-shaped strip 112 back to the inside of the strip pressure groove 110. At this time, the water blocking trough 212 loses its upward force and falls down, no longer blocking the cross valve nozzle 116. Then, the bottom of the U-shaped pressure plate 206 contacts the top of the two-way air cylinder 119, and then the two-way air cylinder 119 is pulled to extend, using the two-way air cylinder 119 to extend. The pull-type air blower design causes the air supply pipe 120 to blow air and pressurize the inside of the water storage tank 115, thereby spraying filtered water from the bottom end of the cross valve nozzle 116 to wash the surface of the photovoltaic panel body 204, washing away residual rainwater and preventing corrosion of the photovoltaic panel body 204 by metal elements after the rainwater dries. Simultaneously, several rollers 205 press down on the scraper 123 to squeeze out excess water. After the horizontal connecting top plate 201 rises to the top, the rectangular protective frame 102 and the positioning frame 203 overlap again, and the photovoltaic panel body 204 generates photovoltaic power, while the rectangular protective frame 102 is located at the bottom of the photovoltaic panel body 204 for heat insulation.
