Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic buildings, and in particular relates to a photovoltaic building integrated curtain wall connection component. Background Art

[0002] Photovoltaic curtain wall is a kind of electricity production by using the wall space of the building and solar energy. It not only effectively alleviates the pressure of urban electricity consumption, but also increases the utilization rate of the building wall. It combines solar panels with curtain walls to ensure the decoration and closure of the building's exterior, while increasing the building's energy-saving and environmental protection performance.

[0003] The unitized photovoltaic curtain wall is one of the most common photovoltaic curtain walls currently available. It is difficult to clean during use and requires people to work at heights. Not only is it highly dangerous, but it is also more time-consuming and labor-intensive to clean, which seriously affects the cleaning effect of the photovoltaic curtain wall. In response to the above-mentioned technical problems, a Chinese patent with patent announcement number CN217388597U uses a sponge wiper to clean the surface of the photovoltaic panel during use, and sprays cleaning liquid onto the surface of the photovoltaic curtain wall through a nozzle. However, after the cleaning liquid contacts and collides with the photovoltaic curtain wall, a large amount of cleaning liquid splashes to the outside, resulting in a large amount of cleaning liquid being wasted. At the same time, the dust is located under the sponge wiper. When the sponge wiper moves, the dust particles will move on the surface of the photovoltaic curtain wall, which can easily cause damage to the surface of the photovoltaic curtain wall. Summary of the invention

[0006] Further technical solution: A first groove for installing the telescopic member is provided on the side wall of the fixed frame, and two groups of the first grooves are provided and are located at the upper and lower sides of the fixed frame.

[0007] Further technical solution: slide grooves are provided on both sides of the movable frame, the cross-section of the slide grooves is T-shaped, a U-shaped movable plate is slidably installed in the slide grooves, a pressure plate is slidably installed on the movable plate, and a fixed screw for driving the pressure plate to move is threadedly connected on the movable plate.

[0008] Further technical solution: A drainage groove is provided on the side wall of the fixed frame, and the drainage groove is connected to a side of the second installation groove close to the movable frame.

[0009] Further technical solution: An exhaust fan is fixedly installed in the second installation groove, and the exhaust fan is located on the side of the limit frame away from the movable frame. The air inlet end of the exhaust fan is connected to a third connecting pipe, which passes through the limit frame and is connected to the second connecting pipe. A valve is provided on the third connecting pipe.

[0010] Further technical solution: An air inlet channel is provided on the top of the movable frame, and a filter is provided at the air inlet end of the air inlet channel.

[0011] Further technical solution: a third groove is provided on the side of the movable frame close to the limiting frame, the third groove is located at the lower side of the limiting frame, and a push plate is arranged in the third groove.

[0012] Further technical solution: Multiple groups of telescopic rods distributed at intervals are fixedly installed in the third groove, and the end of the telescopic rod away from the movable frame is fixedly connected to the push plate. Multiple groups of elastic parts distributed around the telescopic rods are fixedly installed in the third groove, and the movable ends of the elastic parts are fixedly connected to the push plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. At night or when the photovoltaic curtain wall body needs to be cleaned, the closing film, the movable frame and the photovoltaic curtain wall body will form a closed cavity. At the same time, when the movable frame contacts the limit frame, the first connecting tube enters into the second connecting tube and is connected thereto. Then the water pump draws the cleaning liquid in the cleaning liquid tank, and the cleaning liquid enters the closed cavity through the second connecting tube and the first connecting tube. When the closed cavity is full of cleaning liquid, the cleaning liquid injection is stopped. At this time, the surface of the photovoltaic curtain wall body in contact with the sunlight is completely immersed in the cleaning liquid. The dust on the surface of the photovoltaic curtain wall body is cleaned by immersion in the cleaning liquid, thereby avoiding damage to the photovoltaic curtain wall body and ensuring the dust removal effect. At the same time, due to the small space of the cavity, a large amount of cleaning liquid is avoided from being consumed in a single cleaning, thereby further improving the use efficiency of the cleaning liquid.

[0014] 2. When the weather is bad, perform cleaning operations to keep the closed cavity filled with cleaning fluid. The cleaning fluid in the cavity can be used to protect and buffer the photovoltaic curtain wall body, reduce the probability of damage to the photovoltaic curtain wall body, and increase the service life of the equipment.

[0015] 3. After the cleaning liquid is released, the movable frame contacts the limit frame again to form a sealed cavity, and then the exhaust fan extracts the air in the sealed cavity through the third connecting pipe, the first connecting pipe and the second connecting pipe, and the outside air enters the cavity through the air inlet channel after being filtered by the filter, thereby realizing the circulation of the air in the cavity and the outside air, and accelerating the drying of the moisture in the cavity through the air flow, so that the surface of the closed film and the photovoltaic curtain wall body are dried, avoiding the contact of the photovoltaic curtain wall body surface with the outside air when it is wet, and further reducing the probability of dust and impurities adhering to the surface of the photovoltaic curtain wall body.

[0016] 4. When the moving frame moves toward the limit frame, the push plate first presses the closing film against the limit frame, and then the moving frame contacts the limit frame and compresses the elastic member. When the moving frame moves away from the limit frame, the push plate still presses the closing film against the limit frame under the action of the elastic member, thereby ensuring that the cleaning liquid can stably flow downward into the second installation groove when released, avoiding the closing film from detaching from the limit frame and causing leakage of the cleaning liquid, thereby improving the cleanliness of the fixed frame.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1-Figure 8As shown, a photovoltaic building integrated curtain wall connection component provided by the present invention comprises a fixed frame 1, a moving frame 4 is slidably installed in the fixed frame 1, a through groove 10 is provided on the side wall of the moving frame 4 not in contact with the fixed frame 1, a telescopic member 3 for driving the moving frame 4 to move is provided on the fixed frame 1, a first groove 2 for installing the telescopic member 3 is provided on the side wall of the fixed frame 1, two groups of the first groove 2 are provided and are located at the upper and lower sides of the fixed frame 1, a photovoltaic curtain wall body 9 is provided in the moving frame 4, slide grooves 5 are provided on both sides of the moving frame 4, the cross section of the slide groove 5 is T-shaped, a U-shaped moving plate 6 is slidably installed in the slide groove 5, a pressing plate 7 is slidably installed on the moving plate 6, a fixing screw 8 for driving the pressing plate 7 to move is threadedly connected to the moving plate 6, a first connecting pipe 12 is provided at the bottom of the moving frame 4, one end of the first connecting pipe 12 is connected to the through groove 10, and a second groove 11 for installing the first connecting pipe 12 is provided at the bottom of the moving frame 4; A first mounting groove 29 is provided on the upper bottom surface of the fixed frame 1, and a winding shaft 19 driven by a motor is rotatably installed in the first mounting groove 29, a closing film 20 is wound on the winding shaft 19, and a counterweight rod 21 is fixedly installed on the movable end of the closing film 20. A second mounting groove 30 corresponding to the position of the first mounting groove 29 is provided on the lower bottom surface of the fixed frame 1, and a limiting frame 22 of a frame-type structure is fixedly installed in the second mounting groove 30, and the upper end of the limiting frame 22 extends into the first mounting groove 29. When the closing film 20 is in a vertical state, it contacts one side surface of the limiting frame 22. A water pump 14 is fixedly installed on the side of the second installation groove 30 away from the movable frame 4, and the water outlet end of the water pump 14 is connected with the second connecting pipe 13, the second connecting pipe 13 passes through the limiting frame 22 and is used in conjunction with the first connecting pipe 12, when the movable frame 4 contacts the limiting frame 22, the first connecting pipe 12 is connected with the second connecting pipe 13, a cleaning liquid tank 27 is provided at the bottom of the fixed frame 1, the water inlet end of the water pump 14 is connected with the cleaning liquid tank 27, a drainage groove 28 is provided on the side wall of the fixed frame 1, and the drainage groove 28 is connected with the side of the second installation groove 30 close to the movable frame 4.

[0030] In actual application of this embodiment, the photovoltaic curtain wall body 9 is installed in the movable frame 4 and the photovoltaic curtain wall body 9 is closely attached to the movable frame 4, and then the movable plate 6 is installed in the slide groove 5, the movable plate 6 is pushed to the set position and the fixing screw 8 is rotated, and the pressing plate 7 is driven by the fixing screw 8 to move and press the photovoltaic curtain wall body 9 in the movable frame 4 to complete the installation of the photovoltaic curtain wall body 9, and then the telescopic member 3 drives the movable frame 4 to enter the fixed frame 1, and the photovoltaic curtain wall body 9 is protected by the fixed frame 1, and then the fixed frame 1 is fixedly installed in the set position; When in use, the area of ​​the photovoltaic curtain wall body 9 located in the through groove 10 is in contact with sunlight to achieve power generation. At night or when the photovoltaic curtain wall body 9 needs to be cleaned, the winding shaft 19 rotates and releases the closing film 20 under the drive of the motor. The closing film 20 moves vertically downward under the drive of the counterweight rod 21. When the counterweight rod 21 enters the second installation groove 30, the winding shaft 19 stops rotating. At this time, the telescopic member 3 drives the moving frame 4 to move in the direction close to the limit frame 22 until the moving frame 4 contacts the limit frame 22. When the moving frame 4 contacts the limit frame 22, the closing film 20 will be pressed against the limit frame 22, so that the closing film 20, the moving frame 4 and the photovoltaic curtain wall body 9 will form a closed cavity. At the same time, when the moving frame 4 contacts the limit frame 22, the first connecting pipe 12 enters the second connecting pipe 13 and is connected to it. Then the water pump 14 extracts the cleaning liquid in the cleaning liquid tank 27, and the cleaning liquid enters the closed cavity through the second connecting pipe 13 and the first connecting pipe 12. When the closed cavity is full of cleaning liquid, the injection is stopped. The cleaning liquid is then added. At this time, the surface of the photovoltaic curtain wall body 9 that contacts the sunlight is completely immersed in the cleaning liquid. The dust on the surface of the photovoltaic curtain wall body 9 is cleaned by immersion in the cleaning liquid, thereby avoiding damage to the photovoltaic curtain wall body 9 and ensuring the dust removal effect. At the same time, due to the small space of the cavity, a large amount of cleaning liquid is avoided from being consumed in a single cleaning, thereby further improving the efficiency of the use of the cleaning liquid. After the immersion reaches the set time, the telescopic member 3 drives the moving frame 4 away from the limiting frame 22. At this time, the cleaning liquid in the closed cavity flows downward from the gap between the limiting frame 22 and the moving frame 4 into the second mounting groove 30, and then the cleaning liquid flows out of the fixed frame 1 through the drainage groove 28. When the weather is bad, the cleaning operation is performed to keep the closed cavity full of cleaning liquid. The photovoltaic curtain wall body 9 is protected and buffered by the cleaning liquid in the cavity, thereby reducing the probability of damage to the photovoltaic curtain wall body 9 and increasing the service life of the equipment. After the cleaning is completed, the moving frame 4 is away from the limiting frame 22, and then the winding shaft 19 rotates in the opposite direction to wind up the sealing film 20.

[0031] In an example of this embodiment, the telescopic member 3 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the moving frame 4 is driven to move by the electric telescopic rod.

[0032] like Figure 5-Figure 8 As shown, a photovoltaic building integrated curtain wall connection component provided by the present invention is provided. An exhaust fan 15 is fixedly installed in the second installation groove 30. The exhaust fan 15 is located on the side of the limiting frame 22 away from the movable frame 4. The air inlet end of the exhaust fan 15 is connected to the third connecting pipe 16. The third connecting pipe 16 passes through the limiting frame 22 and is connected to the second connecting pipe 13. A valve is arranged on the third connecting pipe 16.

[0033] Specifically, an air inlet channel 17 is opened at the top of the movable frame 4 , and a filter 18 is provided at the air inlet end of the air inlet channel 17 .

[0034] During actual application of this embodiment, after the cleaning liquid is released, the movable frame 4 is brought into contact with the limiting frame 22 again to form a sealed cavity, and then the exhaust fan 15 extracts the air in the sealed cavity through the third connecting tube 16, the first connecting tube 12 and the second connecting tube 13, and the outside air enters the cavity through the air inlet channel 17 after being filtered by the filter 18, thereby realizing the circulation flow of the air in the cavity and the outside air, and accelerating the drying of the moisture in the cavity through the air flow, so that the surface of the sealing film 20 and the photovoltaic curtain wall body 9 are dried, avoiding the contact of the photovoltaic curtain wall body 9 with the outside air when the surface is wet, and further reducing the probability of dust and impurities adhering to the surface of the photovoltaic curtain wall body 9. After drying is completed, the movable frame 4 moves away from the limiting frame 22, and then the winding shaft 19 rotates in the opposite direction to wind up the sealing film 20.

[0035] like Figure 8 , Fig. 9 As shown, a photovoltaic building integrated curtain wall connection assembly provided by the present invention is provided. A third groove 23 is provided on the side of the movable frame 4 close to the limiting frame 22. The third groove 23 is located at the lower side of the limiting frame 22. A push plate 25 is provided in the third groove 23.

[0036] Specifically, multiple groups of telescopic rods 24 are fixedly installed in the third groove 23 and are distributed at intervals. The end of the telescopic rod 24 away from the movable frame 4 is fixedly connected to the push plate 25. Multiple groups of elastic members 26 are fixedly installed in the third groove 23 and are distributed around the telescopic rod 24. The movable end of the elastic member 26 is fixedly connected to the push plate 25.

[0037] In actual application of this embodiment, when the movable frame 4 moves toward the limiting frame 22, the push plate 25 first presses the closing film 20 against the limiting frame 22, and then the movable frame 4 contacts the limiting frame 22 and compresses the elastic member 26. When the movable frame 4 moves away from the limiting frame 22, the push plate 25 still presses the closing film 20 against the limiting frame 22 under the action of the elastic member 26, thereby ensuring that the cleaning liquid can stably flow downward into the second mounting groove 30 when released, avoiding the closing film 20 from detaching from the limiting frame 22 and causing the cleaning liquid to leak out, thereby improving the cleanliness of the fixed frame 1.

[0038] In an embodiment of the present invention, the elastic member 26 is a spring, and can also be other elastic members such as an elastic ball, and the spring applies a thrust to the push plate 25 .

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
