[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Combination Figure 1-5 As shown, this embodiment provides a photovoltaic unobstructed frame structure, including: a main body mechanism 100.

[0026] Among them, the main body mechanism 100 includes a frame body 110, a side panel 120 fixed at the top of the frame body 110, an L-shaped rubber pad 130 embedded in the frame body 110 and the side panel 120, an exhaust pipe 140 fixed at one side of the frame body 110 and connected to the inner cavity of the frame body 110, a one-way valve 150 installed on the inner wall of the exhaust pipe 140, a plurality of air pressure sensors 160 installed at the bottom end of the frame body 110 and extending into the inner cavity of the frame body 110, and a photovoltaic panel body 170 attached to the top of the L-shaped rubber pad 130.

[0027] The frame body 110 is made of aluminum alloy material, which has the advantages of high strength and light weight. A plurality of reinforcing ribs 111 are arranged in an array on the inner wall of the frame body 110 to further enhance the strength of the frame body 110. The side panel 120 is fixed to the top of the frame body 110 to limit the photovoltaic panel body 170 and ensure the stability of the photovoltaic panel body 170.

[0028] The L-shaped rubber pad 130 is used to fix the photovoltaic panel body 170 and increase the sealing between the photovoltaic panel body 170 and the frame body 110 to prevent rainwater from seeping in. It includes a bottom cushion layer 131 embedded in the top of the frame body 110, a side cushion layer 132 whose end is integrally connected to the bottom cushion layer and embedded on the side plate 120, and a semicircular protrusion 133 integrally fixed to the top of the side cushion layer 132. A plurality of circular grooves 1312 are arranged in an array at the top of the bottom cushion layer 131, and a flow channel 1313 is provided at the bottom end of the bottom cushion layer 131 to extend into the inner cavity of the frame body 110. The flow channel 1313 extends into the inner cavity of the frame body 110. One end of 313 is connected to the circular groove 1312, and the other end is connected to the inner cavity of the frame body 110. When the bottom end of the photovoltaic panel body 170 is close to the surface of the bottom cushion layer 131, the vacuum device extracts the air from the inner cavity of the frame body 110 through the exhaust pipe 140, that is, the air in the circular groove 1312 is extracted through the flow channel 1313 to form a vacuum environment. At this time, under the action of atmospheric pressure, the photovoltaic panel body 170 can be tightly attached to the bottom cushion layer 131, thereby achieving fixation between the photovoltaic panel body 170 and the frame body 110 without blocking the surface of the top of the photovoltaic panel body 170.

[0029] A wavy protrusion 1321 is provided on one side of the side cushion layer 132 to ensure the sealing performance between the photovoltaic panel body 170 and the side panel 120. The semicircular protrusion 133 is used to seal the edge of the photovoltaic panel body 170 to prevent rainwater from seeping into the gap between the side cushion layer 132 and the photovoltaic panel, thereby further improving the waterproof effect.

[0030] In addition, a first dovetail groove 112 is opened at the top of the frame body 110, a second dovetail groove 121 is opened on the inner side of the side panel 120, a first dovetail strip 1311 is arranged at the bottom end of the bottom cushion layer 131, the first dovetail strip 1311 is embedded in the first dovetail groove 112, and a second dovetail strip 1322 is arranged on the side cushion layer 132, the second dovetail strip 1322 is embedded in the second dovetail groove 121, thereby facilitating the installation and disassembly of the L-shaped rubber pad 130, that is, facilitating the replacement operation of the L-shaped rubber pad 130.

[0031] The exhaust pipe 140 is used to connect with the vacuum pumping device to facilitate vacuuming the frame body 110 and the inner cavity of the circular groove 1312. The one-way valve 150 is fixed on the inner wall of the exhaust pipe 140 to prevent external air from entering the inner cavity of the frame through the exhaust pipe 140 and destroying the vacuum environment.

[0032] The one-way valve 150 includes an annular seat 151 fixed on the inner wall of the exhaust pipe 140, a support rod 152 fixed in an array on the inner wall of the exhaust pipe 140, a base plate 153 fixed on the end of the support rod 152, a spring 154 with one end fixed on the base plate 153, and a sealing ball 155 fixed on the other end of the spring 154 and close to the annular seat 151. A hemispherical groove is provided on the annular seat 151, and a through hole is provided on the inner wall of the hemispherical groove to pass through the annular seat 151 to facilitate the passage of air flow in the frame. The sealing ball 155 is embedded in the hemispherical groove to seal the through hole to prevent outside air from entering the inner cavity of the frame body 110, and a rubber cushion layer is provided on the inner wall of the hemispherical groove to further improve the sealing performance between the sealing ball 155 and the inner wall of the hemispherical groove. The support rod 152 is used to fix the base plate 153, the base plate 153 is used to install the spring 154, and the spring 154 is used to keep the sealing ball 155 embedded in the hemispherical groove.

[0033] The air pressure sensor 160 is used to monitor the air pressure changes in the inner cavity of the frame body 110 in real time and transmit it to the host computer. The staff can judge whether there is looseness between the photovoltaic panel body 170 and the frame body 110 based on the air pressure changes in the frame body 110. When the air pressure in the frame body 110 is higher than the atmospheric pressure, the fixation of the photovoltaic panel body 170 fails. When the air pressure in the frame body 110 is lower than the atmospheric pressure, the fixation of the photovoltaic panel body 170 remains stable.

[0034] The working principle and use process of the utility model are as follows: when in use, clean the bottom end surface of the photovoltaic panel body 170, place it on the L-shaped rubber pad 130, connect the vacuum device with the exhaust pipe 140, start the vacuum device, and extract the air in the inner cavity of the frame body 110, that is, the air in the circular groove 1312 is extracted together through the flow channel 1313 to form a vacuum environment. At this time, under the action of atmospheric pressure, the photovoltaic panel body 170 is tightly pressed on the L-shaped rubber pad 130 to complete the fixation of the photovoltaic panel body 170 and the photovoltaic frame. After completion, disconnect the vacuum device and the exhaust pipe 140. When the air is pumped out, under the action of air pressure, the sealing ball 155 moves to the side of the bottom plate 153, so that the annular seat 151 opens to facilitate the passage of air. When the air is pumped out, the spring 154 releases its elastic force, driving the sealing ball 155 to stick to the annular seat 151 and close the air pump 140, thereby ensuring the stability of the vacuum environment in the inner cavity of the frame body 110. The air pressure sensor 160 monitors the air pressure changes in the inner cavity of the frame body 110 in real time and transmits it to the upper computer. The staff can judge whether there is looseness between the photovoltaic panel body 170 and the frame body 110 based on the air pressure changes in the frame body 110.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
