Description

Technical Field

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

[0002] Photovoltaic curtain wall is a kind of energy production that utilizes the wall space of the building and adopts solar energy to produce electricity. 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 sealing of the building's exterior, while increasing the building's energy-saving and environmental protection performance.

[0003] The unit-type 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 height. Not only is it more 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 is splashed to the outside, resulting in a large amount of cleaning liquid being wasted. At the same time, dust is located under the sponge wiper. When the sponge wiper moves, 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

[0004] The purpose of the present invention is to provide a photovoltaic building integrated curtain wall connection assembly, aiming to solve the technical problems in the prior art of wasting cleaning fluid during cleaning and easily causing damage to the photovoltaic curtain wall surface.

A water pump is fixedly installed on the side of the second mounting groove away from the movable frame, and a water outlet end of the water pump is connected to a second connecting pipe, and the second connecting pipe passes through the limit frame and is used in conjunction with the first connecting pipe when the movable frame contacts the limit frame. The first connecting pipe is connected to the second connecting pipe when the movable frame contacts the limit frame. A cleaning liquid tank is provided at the bottom of the fixed frame, and a water inlet end of the water pump is connected to the cleaning liquid tank.

[0007] Further technical solution: a first groove for installing the telescopic member is opened on the side wall of the fixed frame, and two groups of first grooves are provided and are located on the upper and lower sides of the fixed frame.

[0008] Further technical solution: There are sliding grooves on both sides of the movable frame, the cross-section of the sliding groove is T-shaped, and a U-shaped movable plate is slidingly installed in the sliding groove. A pressure plate is slidingly installed on the movable plate, and a fixed screw is threadedly connected to the movable plate to drive the pressure plate to move.

[0009] Further technical solution: A drainage groove is provided on the side wall of the fixed frame, and the drainage groove is connected to the side of the second installation groove close to the movable frame.

[0010] Further technical solution: An exhaust fan is fixedly installed in the second mounting 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.

[0011] 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.

[0012] 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 on the lower side of the limiting frame, and a push plate is provided in the third groove.

[0013] 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 end of the elastic part is fixedly connected to the push plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 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 pipe enters the second connecting pipe and is connected to it. 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 pipe and the first connecting pipe. 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 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, which avoids damage to the photovoltaic curtain wall body and ensures 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.

[0016] 2. When the weather is bad, perform cleaning operations and keep the closed cavity filled with cleaning fluid. The cleaning fluid in the cavity can 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.

[0017] 3. After the cleaning liquid is released, the movable frame contacts the limit frame again to form a sealed cavity. 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. The outside air is filtered by the filter and enters the cavity through the air inlet channel, thereby realizing the circulation of air in the cavity and the outside air. The air flow accelerates the drying of moisture in the cavity, thereby drying the sealing film and the surface of the photovoltaic curtain wall body, avoiding contact between the surface of the photovoltaic curtain wall body and 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.

[0018] 4. When the movable frame moves toward the limit frame, the push plate first presses the closing film against the limit frame, and then the movable frame contacts the limit frame and compresses the elastic member. When the movable 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 mounting groove when released, preventing the closing film from detaching from the limit frame and causing leakage of the cleaning liquid, thereby improving the cleanliness of the fixed frame.

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.

[0030] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0032] A first mounting groove 29 is provided on the upper bottom surface of the fixed frame 1, and a reel 19 driven by a motor is rotatably installed in the first mounting groove 29. A closing film 20 is wound on the reel 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. A limit frame 22 of a frame structure is fixedly installed in the second mounting groove 30. The upper end of the limit 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 limit frame 22. A water pump 14 is fixedly installed on the side of the second mounting groove 30 away from the movable frame 4. The water outlet end of the water pump 14 is connected to 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 to the second connecting pipe 13. A cleaning liquid tank 27 is provided at the bottom of the fixed frame 1, and the water inlet end of the water pump 14 is connected to 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 to the side of the second mounting groove 30 close to the movable frame 4.

[0033] 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 tightly 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 fixing screw 8 drives the pressing plate 7 to move and press the photovoltaic curtain wall body 9 into 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 interior of 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;

[0034] When in use, the area of ​​the photovoltaic curtain wall body 9 located in the through groove 10 is exposed to sunlight to generate electricity. At night or when the photovoltaic curtain wall body 9 needs to be cleaned, the winding shaft 19 rotates under the drive of the motor and releases the closing film 20. The closing film 20 moves vertically downward under the drive of the counterweight rod 21. When the counterweight rod 21 enters the second mounting groove 30, the winding shaft 19 stops rotating. At this time, the telescopic part 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 added. At this time, the surface of the photovoltaic curtain wall body 9 in contact with 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, which avoids damage to the photovoltaic curtain wall body 9 and ensures 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, further improving the efficiency of the use of the cleaning liquid. After the soaking reaches the set time, the telescopic part 3 drives the movable frame 4 away from the limit frame 22. At this time, the cleaning liquid in the closed cavity flows downward from the gap between the limit frame 22 and the movable 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, reducing the probability of damage to the photovoltaic curtain wall body 9 and improving the service life of the equipment. After the cleaning is completed, the movable frame 4 is away from the limit frame 22, and then the winding shaft 19 rotates in the opposite direction to rewind the sealing film 20.

[0035] 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.

[0036] like Figure 5-Figure 8 As shown, a photovoltaic building integrated curtain wall connection component provided by the present invention, an exhaust fan 15 is fixedly installed in the second installation groove 30, the exhaust fan 15 is located on the side of the limit frame 22 away from the movable frame 4, and 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 limit frame 22 and is connected to the second connecting pipe 13, and a valve is provided on the third connecting pipe 16.

[0037] Specifically, an air inlet channel 17 is opened on the top of the movable frame 4 , and a filter 18 is provided at the air inlet end of the air inlet channel 17 .

[0038] During actual application of this embodiment, after the cleaning liquid is released, the movable frame 4 contacts 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 pipe 16, the first connecting pipe 12 and the second connecting pipe 13. The outside air is filtered by the filter 18 and enters the cavity through the air inlet channel 17, thereby realizing the circulation of air in the cavity and the outside air. The air flow accelerates the drying of moisture in the cavity, thereby drying the surface of the sealing film 20 and the photovoltaic curtain wall body 9, avoiding contact with the outside air when the surface of the photovoltaic curtain wall body 9 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.

[0039] like Figure 8 、 Figure 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 limit frame 22. The third groove 23 is located on the lower side of the limit frame 22. A push plate 25 is provided in the third groove 23.

[0040] Specifically, multiple groups of telescopic rods 24 distributed at intervals are fixedly installed in the third groove 23, and 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 distributed around the telescopic rod 24 are fixedly installed in the third groove 23, and the movable end of the elastic member 26 is fixedly connected to the push plate 25.

[0041] In actual application of this embodiment, when the movable frame 4 moves toward the limit frame 22, the push plate 25 first presses the closing film 20 against the limit frame 22, and then the movable frame 4 contacts the limit frame 22 and compresses the elastic member 26. When the movable frame 4 moves away from the limit frame 22, the push plate 25 still presses the closing film 20 against the limit 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, preventing the closing film 20 from detaching from the limit frame 22 and causing the cleaning liquid to leak out, thereby improving the cleanliness of the fixed frame 1.

[0042] In one embodiment of the present invention, the elastic member 26 is a spring, and can also be other elastic components such as an elastic ball, and the spring applies a thrust to the push plate 25 .

[0043] 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 scope of protection of the present invention.

[0044] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method 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 can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
