[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-strength photovoltaic aluminum profile frame, comprising a first frame rod body constituting a frame bracket and a second frame rod body with a buffer pad arranged on the surface, the first frame rod body and the second frame rod body constitute an aluminum profile frame with an inclined distribution posture, and the second frame rod body is used to support the photovoltaic panel from the bottom end, the first frame rod body and the second frame rod body are also connected by a support rod, wherein a bending portion is provided at the connection between the support rod and the frame rod body, and the bending portion is used to position the support rod as a whole below the back mounting surface of the photovoltaic panel.

[0007] Preferably, the first frame rod body and the second frame rod body are respectively provided with a first reinforcement tube and a second reinforcement tube, wherein the outer surface of the reinforcement tube contacts the inner end of the reinforcement plate, and the outer end of the reinforcement plate is fixed to the inner wall of the corner of the frame rod body.

[0008] Preferably, the support rod is a hollow structure, and its two ends are connected to the bottom of the internal space of the first reinforcement tube and the second reinforcement tube respectively through the bending parts. At the same time, the three constitute a cooling mechanism, which is used to cool the photovoltaic panel from the back of the photovoltaic panel.

[0009] Preferably, the support rod and the first reinforcement tube and the second reinforcement tube at both ends thereof together constitute an evaporative cooling mechanism, wherein the interior of the second reinforcement tube and the lower half of the support rod are filled with heat-absorbing liquid, and the reinforcement tube, the support rod and the frame rod body together form an inclined distribution posture, the heat-absorbing liquid evaporates and absorbs heat, and the steam climbs upward into the first reinforcement tube.

[0010] Preferably, a retractable mechanism is provided at the top end of the first reinforcement tube, and the retractable mechanism absorbs water vapor under high temperature conditions and allows the condensed heat-absorbing liquid to flow back into the support rod under low temperature conditions.

[0011] Preferably, the retractable mechanism comprises a water-absorbing strip made of a flexible material, and a pressure plate made of a memory alloy and installed inside the first reinforcing tube is provided below the water-absorbing strip.

[0012] Preferably, the support rod, the reinforcing tube and the water pump together constitute a water-cooled cooling mechanism, wherein the disconnection points of two adjacent support rods are respectively connected to the output end and the input end of the drive box.

[0013] Preferably, a vertical shaft is rotatably mounted on the axis of the drive box, and paddle blades distributed at equal angles and located inside the drive box are fixed on the surface of the vertical shaft, and two rope bodies are fixed to the bottom end of the vertical shaft, wherein the rope bodies move through the vertical cylinder and a counterweight ball is fixed to the bottom end of the rope bodies, and the top end of the vertical cylinder is rotatably mounted on the bottom wall of the drive box.

[0014] A method for preparing a high-strength photovoltaic aluminum profile frame, the method comprising the following steps:

[0015] Step 1: Use spot welding or other existing methods to fix the reinforcement plate on the outer surface of the first reinforcement tube and the second reinforcement tube according to the corner shape of the frame rod body, and after completing the above steps, insert and weld the corresponding reinforcement tube into the first rod or the second rod, and the support rod is used as a post-installed part. After the above components are punched, the support rod is installed on each rod structure through the bending part, and the support rod is connected to the inside of each reinforcement tube.

[0016] Step 2: In actual use, the water pump, reinforcement tube and support rod or water tank structure form a closed water flow path, and the water flow is used to cool the photovoltaic panel.

[0018] 1. The support rod is designed with its bent part to reinforce the entire frame of the profile and provide stable support for the photovoltaic panel from the back. At the same time, the structural design of the reinforcement plate and each reinforcement tube can reinforce the frame rod from the inside.

[0019] Furthermore, the hollow structure design inside the support rod and each reinforcement tube provides space for accommodating the heat absorbing liquid, so that the space of the support rod and each reinforcement tube can serve as an environment for the heat absorbing liquid to switch between evaporation and condensation states, thereby achieving the effect of heat absorption and cooling;

[0020] Furthermore, the structural design of the water absorption strip and the pressure plate enables them to absorb water and squeeze out water according to the change of ambient temperature, thereby ensuring the circulation of evaporation, condensation and cooling of the heat absorption liquid;

[0021] 2. The blade structure is used in conjunction with an external water pump, so that the internal space of the support rod and each reinforcement tube can be used as a space for the circulation of heat-absorbing liquid, and the circulation of the heat-absorbing liquid is used to absorb heat to achieve cooling, which is more sustainable;

[0022] Furthermore, the structural design inside the drive box ensures that the flow of water can not only cool the photovoltaic panels, but also use the impact force on the blades to rotate the vertical axis, so that the vertical axis rope can produce different motion states according to the different water flow rates, thereby achieving different effects. The design is reasonable and the cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 9 , the present invention provides the following technical solutions:

[0035] Embodiment 1: In this embodiment, in order to solve the problems existing in the prior art, the following solution is disclosed. Figure 1-Figure 2 The improvement direction is mainly reflected in the reinforcement of the connection between the profiles and the reinforcement of the profiles themselves, including a first frame rod body 1 constituting a frame bracket and a second frame rod body 2 with a buffer pad 8 on the surface. The first frame rod body 1 and the second frame rod body 2 constitute an aluminum profile frame with an inclined distribution posture, and the second frame rod body 2 is used to support the photovoltaic panel from the bottom end. The first frame rod body 1 and the second frame rod body 2 are also connected by a support rod 3, wherein a bending portion 4 is provided at the connection between the support rod 3 and the frame rod body, and the bending portion 4 is used to position the support rod 3 as a whole below the back mounting surface of the photovoltaic panel. The first frame rod body 1 and the second frame rod body 2 are respectively provided with a first reinforcement tube 6 and a second reinforcement tube 7, wherein the outer surface of the reinforcement tube is connected to the photovoltaic panel. The inner ends of the reinforcing plates 5 are in contact, while the outer ends of the reinforcing plates 5 are fixed to the inner walls of the corners of the frame rod bodies. In the prior art, a rod structure is also used as a connecting mechanism between the first frame rod body 1 and the second frame rod body 2. The support rod 3 in this solution can not only serve as a reinforcing member between the frame rod bodies, but also utilize the bending portion 4 so that the existence of the support rod 3 will not affect the normal use of the photovoltaic panel. In addition, a first reinforcing tube 6 and a second reinforcing tube 7 are respectively designed inside the first frame rod body 1 and the second frame rod body 2. The tube body cooperates with the reinforcing plate 5 outside it to play a better anti-deformation role, and the hollow structure inside the tube body can also serve as a cable accommodation structure, making the exterior of the photovoltaic frame neater and providing better protection.

[0036] Photovoltaic panels are used in an external environment for a long time with photovoltaic aluminum profile frames. Therefore, when the operating temperature of the photovoltaic panels themselves and the ambient temperature are high, the lack of cooling will lead to a reduction in the overall service life of the photovoltaic components. Therefore, in order to solve this problem, the following solutions are disclosed in this embodiment. Figure 4-6 As shown, the support rod 3 is a hollow structure, and its two ends are connected to the bottom of the internal space of the first reinforcement tube 6 and the second reinforcement tube 7 through the bending part 4, and the three constitute a cooling mechanism at the same time. The cooling mechanism is used to cool the photovoltaic panel from the back of the photovoltaic panel. The support rod 3 and the first reinforcement tube 6 and the second reinforcement tube 7 at both ends together constitute an evaporative cooling mechanism, wherein the interior of the second reinforcement tube 7 and the lower half of the support rod 3 are filled with heat-absorbing liquid, and the reinforcement tube, the support rod 3 and the frame rod body together form an inclined distribution posture, the heat-absorbing liquid evaporates and absorbs heat, and the steam climbs upward to the first reinforcement tube 6, and the top of the first reinforcement tube 6 is provided with a retractable mechanism, which absorbs water vapor under high temperature conditions and allows the condensed heat-absorbing liquid to flow back to the support rod 3 under low temperature conditions, and the retractable mechanism includes a water-absorbing strip 9 made of flexible material, and a pressure plate 10 made of memory alloy installed in the first reinforcement tube 6 is provided below the water-absorbing strip 9. The second frame rod body 2 and the support rod 3 are both located below the back of the photovoltaic panel, so the heat generated during operation will directly act on the heat-absorbing liquid. The high-intensity operation combined with the heating effect generated by the ambient temperature will cause the heat-absorbing liquid to partially evaporate, so it will also absorb a large amount of heat during the evaporation process, and the evaporated water vapor will enter the first frame rod body 1 and be absorbed by the water-absorbing strip 9 in the first frame rod body 1. The water-absorbing strip 9 itself is a porous structure with average thermal conductivity, while the pressure plate 10 connected to the first reinforcing cylinder 6 is more sensitive to temperature and is a memory alloy material. Therefore, under high temperature conditions, the water-absorbing strip 9 will be stretched to enable it to have water-absorbing conditions. At night or when the photovoltaic module stops operating, that is, under low temperature conditions, the pressure plate 10 will deform and produce an extrusion effect on the water-absorbing strip 9, so the heat-absorbing liquid will be squeezed and flow into the support rod 3, thereby realizing the repeated use of the heat-absorbing liquid and achieving a more convenient and low-cost cooling effect.

[0037] Embodiment 2: In this embodiment, a different cooling solution is disclosed. On the basis of the cooling solution, water flow is used as a power source to deal with weeds under the photovoltaic panels. A large number of photovoltaic modules are used in combination in outdoor environments. Although the area covered below is insufficiently illuminated, the growth of weeds may affect the normal use and maintenance of the photovoltaic panels. Therefore, this embodiment discloses how to Figure 7-Figure 8In the scheme shown, the support rod 3, the reinforcement tube and the water pump together constitute a water-cooled cooling mechanism, wherein the disconnection points of two adjacent support rods 3 are respectively connected to the output end and the input end of the drive box 11, and a vertical shaft 12 is rotatably installed on the axis of the drive box 11, and the surface of the vertical shaft 12 is fixed with blades 13 which are distributed at equal angles and are located inside the drive box 11, and two rope bodies 14 are fixed at the bottom end of the vertical shaft 12, wherein the rope body 14 moves through the vertical tube 16 and a counterweight ball 15 is fixed at the bottom end of the rope body 14, and the top of the vertical tube 16 is rotatably installed on the bottom wall of the drive box 11, which is specifically manifested in that the output end and the input end of the water pump are respectively connected to the two reinforcement tubes, so that the water pump, the reinforcement tube and the support rod 3 or the water tank structure constitute a closed water flow path, and the water flow is used to cool the photovoltaic panel and dissipate the heat. At the same time, during the flow of water, The blades 13 are impacted, thereby driving the vertical shaft 12 and the rope body 14 at its bottom to rotate. Under the action of centrifugal force, the counterweight ball 15 drives the rope body 14 to unfold with the bottom end of the vertical cylinder 16 as the fulcrum. The movable vertical cylinder 16 is passed through by the rope body 14 to ensure that the rope body 14 can fully clean the weeds in the horizontal direction during the rotation process. Whether the counterweight ball 15 will drive the rope body 14 to rotate and unfold depends on the rotation of the vertical shaft 12, that is, the flow rate of the water flow. Therefore, in actual use, the rotation speed of the vertical shaft 12 can be adjusted by adjusting the water pump operating rate to change the water flow rate, so that the rope body 14 can rotate to a specified angle during the rotation process, thereby achieving different effects, such as single water cooling at low speed, water cooling and weed cleaning at high speed, or the collision between the counterweight balls 15 at variable speed to produce noise to drive away birds and insects.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
