[0035] Embodiment 2, on the basis of embodiment 1, the side rubber strips 204 on the back of the middle cross bar 201 can be set to a structure with low sides and high middle part. The side rubber strips 204 can more quickly introduce water flow into the inside of the side rubber strips 204 in the vertical direction on both sides, thereby improving the water flow rate. At the same time, the upper and lower parts of the middle rubber wedge block 205 of the vertical curtain plate connecting angle steel 203 are a structure that gradually narrows outward, thereby reducing the resistance to the water flow. At the same time, the resistance of the middle rubber wedge block 205 also plays a role in reducing the water flow speed. The reduction in water flow speed can reduce the scouring and erosion of the curtain plate connecting angle steel 203 and the side rubber strips 204 by water flow, thereby extending the service life.
[0036] Working principle of this embodiment: The photovoltaic screen panel 1 is manufactured by combining a glass panel and a photovoltaic panel. The glass on the outside of the photovoltaic screen panel 1 plays a protective role. The photovoltaic screen panel 1 is set on the outer wall of the building, and generates electricity by utilizing the restricted outer wall of the building. The hole position of the middle fixing seat 303 is fixedly connected with the wall expansion bolt, and then the vertical bracket 2 and the middle cross bar 201 are fixed by the angle steel connector 202 with screws. The vertical bracket 2 and the middle cross bar 201 constitute a fixing bracket for the photovoltaic screen panel 1 in the horizontal and vertical directions. The middle T-shaped fixing frame 3 is set in the middle and on both sides. The middle T-shaped fixing frame 3 and the inner insulation tube 302 are of different materials. The inner insulation tube 302 is made of rubber and other materials with low heat transfer efficiency. The middle T-shaped fixing frame 3 is connected to the inner insulation tube 302 through the inner insulation tube 302. The middle fixing frames 304 on both sides are used to block and cut off heat and low temperature. The middle T-shaped fixing frame 3 is used to block and cut off heat and low temperature through the inner insulation pipe 302 and the middle fixing seat 303. The inner insulation pipe 302 separates the adjacent middle T-shaped fixing frames 3, cuts off the transfer of heat and low temperature between the middle T-shaped fixing frame 3, the middle fixing seat 303 and the middle fixing frame 304, reduces the energy transfer of the middle T-shaped fixing frame 3 to the building wall through the middle fixing seat 303, reduces the interference with the thermal insulation effect of the passive building, and avoids the middle T-shaped fixing frame 3, the middle fixing seat 303 and the middle fixing frame 304 made of metal materials being exposed to high temperatures in summer to transfer heat to the building, resulting in a decrease in the thermal insulation effect of the passive building. The same principle also applies in winter.
[0037] The upper stud 305 at the top of the middle fixing frame 304 slides into the upper connecting groove 301, and the nut guided by the external thread of the upper stud 305 moves downward, and the nut pushes the upper fixing cover 306 downward while moving downward, and the nut fastens the upper fixing cover 306 to fit the middle T-shaped fixing frame 3, and the clamping of the nut fixes the middle fixing frame 304 and the middle T-shaped fixing frame 3. The middle fixing frame 304 is assembled in sections, which reduces the overall length of the middle fixing frame 304, greatly reduces the weight of the middle fixing frame 304, and reduces the installation difficulty of the middle fixing frame 304. The other end of the middle fixing frame 304 can also be provided with the same structure as the upper connecting groove 301 of the middle T-shaped fixing frame 3, which is used for serial fixed connection of multiple middle fixing frames 304 to extend the spacing of the middle T-shaped fixing frames 3;
[0038] The middle connecting screw 206 drives the middle rubber wedge block 205 to move close to the inner side of the side rubber strip 204 and the curtain panel connecting angle steel 203, and the middle rubber wedge block 205 squeezes the side rubber strip 204 outward to promote the close clamping and fitting of the side rubber strip 204 and the side of the photovoltaic screen panel 1. The U-shaped channel of the side rubber strip 204 on the back of the middle crossbar 201 and the curtain panel connecting angle steel 203 are connected with the U-shaped channel of the side rubber strip 204 on the back of the vertical bracket 2 and the curtain panel connecting angle steel 203 on both sides, which can not only seal the gap between the photovoltaic screen panels 1, but also play the effect of draining water and rainwater, and reduce the dust marks left by water flowing through the photovoltaic screen panel 1. The flow of water in the vertical direction between the side rubber strip 204 on the back of the vertical bracket 2 and the curtain panel connecting angle steel 203 can drive the air flow to generate low pressure, and the low pressure attracts the rainwater around the photovoltaic screen panel 1 to gather toward both sides and accelerate the flow rate of rainwater, thereby reducing the rainwater on the surface of the photovoltaic screen panel 1 and reducing the dust marks left by rainwater.
