DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] like Figures 1-8 As shown, a photovoltaic mounting auxiliary frame applied to the side of a BIPV house comprises a cross 1 formed by welding three galvanized square tubes and a frame 2 fixed by welding four galvanized square tubes. The cross 1 is fixedly mounted inside the frame 2. The frame 2 also comprises: two mounting ears 3, which are fixedly mounted at both ends of the frame 2, and the frame 2 is connected to the pre-buried bolts on the house frame through the mounting ears 3. The fixing unit 4 is arranged on the end face of the frame 2, and the fixing unit 4 is used to fix the photovoltaic panel. The fixing unit 4 comprises a fixing unit 4 fixedly mounted at the end of the cross 1. The frame-type elastic support pad 41 is provided on the surface, and four Z-shaped pressing plates 42 are provided on the outside of the frame-type elastic support pad 41. Each Z-shaped pressing plate 42 is detachably connected to the end face of the frame frame 2. The end face of the cross 1 is fixedly installed with multiple Z-shaped elastic metal sheets 43. Through the action of the frame-type elastic support pad 41 and the Z-shaped elastic metal sheets 43, it can be ensured that the photovoltaic panel is firmly installed, so that the photovoltaic panel has a certain elastic and retractable moving space (about 1-1.5CM), so that when facing strong winds and other weather outdoors, the hard impact of wind flow on the photovoltaic panel can be reduced.

[0032] Multiple adsorption units 5 are installed on the end face of the cross 1. The interior of the cross 1 is interconnected, and each adsorption unit 5 is connected to the interior of the cross 1. The adsorption unit 5 is used to adsorb photovoltaic panels. Each adsorption unit 5 includes a mounting tube 51 fixedly plugged into the end face of the cross 1, and a negative pressure suction cup 52 is fixedly plugged into the top of the mounting tube 51. The height of the negative pressure suction cup 52 is higher than the top of the Z-shaped elastic metal sheet 43.

[0033] The negative pressure suction unit 6 is installed on the side of the cross 1 away from the adsorption unit 5, and the negative pressure suction unit 6 is connected to the interior of the cross 1. The negative pressure suction unit 6 includes a cylinder sleeve 61 fixedly inserted in the end of the cross 1 away from the mounting tube 51, and the interior of the cylinder sleeve 61 is slidably connected with a piston 62, and the end surface of the piston 62 is provided with an air outlet 63. A sealing cover 64 is installed on the top of the cylinder sleeve 61, and the end surface of the sealing cover 64 is provided with an air inlet 65. A one-way valve 66 is installed inside the air inlet 65 and the air outlet 63.

[0034] The side wall of the frame 2 is provided with two ventilation holes 7 connected with the interior of the cross 1. Two end covers 8 corresponding to the positions of the ventilation holes 7 are fixedly installed inside the cross 1. The side walls of the two end covers 8 are provided with sealing holes 9, and the insides of the two sealing holes 9 are provided with sealed electric control valves 10. The side wall of the frame 2 is provided with multiple heat dissipation holes 11 connected with the sealing holes 9. The heat dissipation holes 11 can increase the natural airflow on the back of the photovoltaic panel.

[0035] Mounting holes 12 are provided on both sides of the end face of the cross 1, and support plates 13 are installed inside the two mounting holes 12, and the end faces of the two support plates 13 are fixedly plugged with metal elastic plates 14, and the tops of the two metal elastic plates 14 are both against the bottoms of the Z-shaped elastic metal sheets 43 on the same side. The top of the cross 1 is located on one side of the two metal elastic plates 14 and is fixedly installed with hanging blocks 15, and the two hanging blocks 15 are fixedly installed with hanging ropes 16, and the two hanging ropes 16 are connected to steel balls 17. The cylinder sleeve 61 is installed with a blowing mechanism 18, which drives the steel balls 17 to shake and hit the metal elastic plates 14 through the hanging ropes 16, so that the metal elastic plates 14 can transmit vibration force to the photovoltaic panels through the Z-shaped elastic metal sheets 43.

[0036] The blowing mechanism 18 includes two mounting tubes 181 fixedly mounted on the inner wall of the cylinder sleeve 61, and the two mounting tubes 181 are both arranged above the piston 62. The inside of the two mounting tubes 181 is fixedly mounted with a blowing electric control valve 182, and the inside of the air outlet hole 63 is fixedly mounted with an air outlet electric control valve 183. The side wall of the cylinder sleeve 61 is provided with two conical holes 184 on the same horizontal line as the steel ball 17, and the aperture of the air inlet end of the two conical holes 184 is larger than the aperture of the air outlet end. The two conical holes 184 are both connected to the mounting tube 181 on the same side. Since the aperture of the air outlet end of the conical hole 184 is smaller than the aperture of the air inlet end, when the air flow is discharged through the conical hole 184, the air flow velocity will become faster due to the increase in discharge pressure, thereby increasing the air flow impact force on the steel ball 17.

[0037] A support ring 19 is fixedly installed on the inner wall of the cylinder sleeve 61 below the piston 62, and a support spring 20 is installed between the support ring 19 and the piston 62. An iron ring 21 is fixedly installed on the bottom of the piston 62, and an electromagnetic ring 22 is fixedly installed on the top of the support ring 19. A pull rod 23 is fixedly inserted into the bottom of the piston 62. The pull rod 23 is hollow and connected to the air outlet 63. The handle of the pull rod 23 is set below the support ring 19. Through the electromagnetic ring 22, the industrial control end of the photovoltaic system can control the movement of the piston 62, and through the pull rod 23, it is convenient for the staff to manually control the movement of the piston 62 during the installation stage of the photovoltaic panel. Electromagnetic shielding structures need to be set at the cylinder sleeve 61 and the sealing cover 64 to avoid affecting the normal operation of the photovoltaic panel, and the support spring 20 is a non-magnetic spring to avoid being affected by the magnetism of the electromagnetic ring 22.

[0038] The operating principle of the present invention is now described as follows: the photovoltaic panel to be installed is installed on the cross 1 and the frame 2, so that it is close to the negative pressure suction cup 52 (the entire frame 2 and the photovoltaic panel are tilted, leaving the back space of the frame 2). Then, the staff pulls out the pull rod 23, and the piston 62 moves outward synchronously, thereby increasing the space between the piston 62 and the sealing cover 64. At this time, under the action of the pressure difference, the air inside the cross 1 is sucked into the cylinder sleeve 61, and then the staff pushes back the pull rod 23, and the piston 62 moves back. Under the compression effect of the cylinder sleeve 61 and the one-way valve 66 inside the air inlet 65 and the air outlet 63, the air inside the cylinder sleeve 61 is discharged through the air outlet 63. By continuously pulling and pulling the pull rod 23, the air inside the cross 1 can be continuously discharged. Since each mounting cylinder 51 is connected to the interior of the cross 1, the air inside each negative pressure suction cup 52 is gradually reduced. At this time, an air pressure difference is formed between the inside and outside of the negative pressure suction cup 52. Under the action of the pressure difference, the negative pressure suction cup 52 and the photovoltaic panel are stably adsorbed, so that the photovoltaic panel can be pre-fixed by the negative pressure suction cup 52.

[0039] Then, lay the frame 2 and the photovoltaic panel flat, and install each Z-shaped pressing piece 42 on the frame 2 (fasten and fix it by bolts or screws). At this time, the horizontal part of the upper side of the Z-shaped pressing piece 42 will cover the outer edge of the photovoltaic panel, so that the photovoltaic panel can be pressed onto the frame 2 to achieve the effect of fixing the photovoltaic panel. Then, the frame 2 can be lifted by lifting equipment and moved to the installation location. The mounting ears 3 are connected to the pre-buried bolts on the house frame and locked with nuts. Since the photovoltaic panel can be installed with the frame 2, it can be fixed by screws or bolts. The negative pressure suction cup 52 is used for pre-adsorption and fixation. Therefore, when the Z-shaped pressing piece 42 is subsequently installed, the stability of the photovoltaic panel can be ensured, and there is no need to hold the photovoltaic panel with hands all the time. The adsorption effect of the negative pressure suction cup 52 can share part of the vertical load of the photovoltaic panel, reduce the supporting burden of each Z-shaped pressing piece 42, and indirectly improve the stability of the photovoltaic panel installation. At the same time, since the BIPV house is pre-embedded with bolts on its frame during construction, not only can the step of installing fixings on the wall be omitted, but the photovoltaic panel load can also be directly transferred to the house frame, and the overall stability is higher.

[0040] At the same time, after the photovoltaic panels are installed, the electromagnetic rings 22 inside each cross 1 are connected to the industrial control end of the photovoltaic system. When the detection end of the photovoltaic system detects that the temperature of the photovoltaic panel has risen (the temperature of the photovoltaic panel can be monitored in real time by using a temperature detection sensor as the detection end), the photovoltaic system controls the sealed electric control valves 10 at the two end covers 8 to be energized and opened. At this time, the galvanized square tube of the frame 2 is connected to the interior of the cross 1 through the sealing hole 9, so the external air will be replenished into the interior of the cross 1. Subsequently, the photovoltaic system controls each electromagnetic ring 22 to operate at a frequency of energizing for 2 seconds and de-energizing for 3 seconds. When the electromagnetic ring 22 is energized, it will generate a magnetic attraction to the iron ring 21, thereby attracting the piston 62 to move downward. At this time, the air inside the cross 1 is sucked into the cylinder sleeve 61, and when the electromagnetic ring 22 is de-energized, the support spring Under the action of 20, the piston 62 moves back and resets. At this time, the air inside the cylinder sleeve 61 is discharged through the air outlet 63. By continuously sucking air, the external air can flow through the heat dissipation holes 11, the sealing holes 9, the cylinder sleeve 61 and other positions. By accelerating the air flow around the photovoltaic panel, the temperature of the photovoltaic panel can be effectively reduced to prevent the high temperature from affecting the working efficiency of the photovoltaic panel (the efficiency drops by about 0.3% to 0.5% for every 1°C increase in the temperature of the photovoltaic panel). When the temperature detection end of the photovoltaic system detects that the temperature has returned to normal, the electromagnetic ring 22 is controlled to continue working for 2 minutes, and then the electromagnetic ring 22 and the sealing electric control valve 10 are controlled to be de-energized. At the same time, the electromagnetic ring 22 is controlled to work again at the aforementioned frequency for 30 seconds, so that the air inside the cross 1 is extracted again, and each negative pressure suction cup 52 can stably adsorb the photovoltaic panel;

[0041] Meanwhile, the photovoltaic system will regularly control electromagnetic ring 22, spray electric valve 182, two sealing electric valves 10 and outlet electric valve 183 to work. Electromagnetic ring 22 works at the frequency of 2 seconds of power-on and 3 seconds of power-off. Spray electric valve 182 and sealing electric valve 10 are powered on to open, while outlet electric valve 183 is powered on to close. At this time, when piston 62 is powered off, the compressed air inside cylinder sleeve 61 will be sprayed out through spray electric valve 182 via conical hole 184. Since the inlet hole diameter of conical hole 184 is larger than the outlet hole diameter, the flow rate of the airflow will increase when the airflow is sprayed out of conical hole 184, and the airflow will be sprayed towards steel ball 17. Steel ball 17 will be hit towards metal elastic plate 14 under the action of the airflow. Metal elastic plate 14 will conduct vibration force to Z-shaped elastic metal sheet 43 under the action of the impact. The vibration force will be conducted to the photovoltaic panel through Z-shaped elastic metal sheet 43, so that slight vibration force can be generated at the photovoltaic panel. Under the action of the vibration force, dust and the like on the surface of the photovoltaic panel will be shaken off, so that the effect of dust and the like on the photovoltaic panel to receive light can be avoided as much as possible. Electromagnetic ring 22 is powered on for a total of 2 minutes. After 2 minutes, the photovoltaic system controls sealing electric valve 10 and spray electric valve 182 to be powered off and closed, and controls outlet electric valve 183 to be re-opened. Then, electromagnetic ring 22 is controlled to work again at the above-mentioned frequency for 30 seconds, so that the air inside cross 1 is extracted again, and each negative pressure suction cup 52 stably adsorbs the photovoltaic panel.

[0042] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
