Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic curtain walls, in particular to a photovoltaic energy-saving curtain wall component. Background Art

[0002] Photovoltaic curtain wall combines solar photovoltaic power generation technology with building curtain walls, using photovoltaic glass instead of ordinary curtain wall panels. In addition to its power generation characteristics, it has the same architectural characteristics as other curtain walls. Photovoltaic curtain walls can not only save energy, but also increase production capacity.

[0003] At present, since the surface of the photovoltaic curtain wall is exposed to the atmosphere for a long time, dust is easily accumulated on the surface. Therefore, Chinese patent CN219773299U discloses a building assembled photovoltaic curtain wall. The curtain wall is provided with a cleaning device, so that the T-block slides on the inner wall of the T-slot, and then the brush plate and bristles on the T-block move, thereby cleaning the dust accumulated on the surface of the photovoltaic panel body, so that the photovoltaic panel body is not affected by the sun's radiation, thereby improving the conversion efficiency.

[0004] However, the above device still has the following defects. When the photovoltaic curtain wall is installed and used in some areas with relatively high sand content in the air, such as cities in the north with strong sandstorms, the amount of dust adhering to the surface of the photovoltaic curtain wall will be relatively more. If it rains, the rain will combine with the dust in the air or on the surface of the curtain wall and adhere to the surface of the curtain wall, and form stubborn mud spots after the water evaporates. If it is wiped directly, hard impurities may scratch the glass surface, thereby damaging the surface of the photovoltaic curtain wall. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 The utility model provides a technical solution: a photovoltaic energy-saving curtain wall assembly, including a photovoltaic curtain wall 1 and a bracket keel 4 installed on the back of the photovoltaic curtain wall 1, the bracket keel 4 is installed on the wall through a mounting bracket 3 and can be rotated and adjusted, and also includes:

[0028] A folding plate 2 is installed at the bottom of the photovoltaic curtain wall 1. The folding plate 2 and the outer walls of the photovoltaic curtain wall 1 near both sides are provided with tracks 5. A driven slider 7 and a slidably adjustable electric slider 6 are slidably installed in the two tracks 5. The driven slider 7 and the electric slider 6 are connected by a connecting part.

[0029] A cloth-winding roller 8 is rotatably mounted between two driven sliders 7, a water-permeable cloth is wound around the outer wall of the cloth-winding roller 8, and the edge of the water-permeable cloth is fixedly connected to the outer wall of the folding plate 2, and a walking wheel 10 is also fixed to the outer wall of the cloth-winding roller 8 so as to be in frictional contact with the outer wall of the photovoltaic curtain wall 1;

[0030] A rotating tube 17 is installed between the two electric sliders 6, and a wiping roller 9 is fixed to the outer wall of the rotating tube 17, the wiping roller 9 is in contact with the surface of the photovoltaic curtain wall 1, and the rotating direction of the rotating tube 17 can be switched and adjusted;

[0031] The water spraying part is arranged in the wiping roller 9 , and the cleaning liquid can seep out through the surface of the wiping roller 9 and be coated on the surface of the photovoltaic curtain wall 1 .

[0032] When the photovoltaic energy-saving curtain wall assembly is in use, it can be installed on the wall through the mounting bracket 3 and the bracket keel 4. Figure 5 The photovoltaic curtain wall 1 and the mounting bracket 3 can be rotated and adjusted. The specific adjustment method can be a bracket support method, etc. For details, please refer to the rotation opening method of the existing photovoltaic curtain wall, so that the angle can be adjusted in the vertical direction, such as the window position of the wall;

[0033] In the initial state, the electric slider 6 and the driven slider 7 are both in the track 5 on the folding plate 2, and will not block the surface of the photovoltaic curtain wall 1. Then, when cleaning the surface of the photovoltaic curtain wall 1, the electric slider 6 is first controlled to slide upward, and the wiping roller 9 will roll along the surface of the photovoltaic curtain wall 1. At the same time, the cleaning liquid sprayed by the water spray part will seep out through the surface of the wiping roller 9 and be coated on the surface of the photovoltaic curtain wall 1. In addition, the rolling of the wiping roller 9 will not wipe the stubborn mud spots, so as to avoid scratches on the surface of the photovoltaic curtain wall 1 in the process.

[0034] At the same time, the electric slider 6 will drive the driven slider 7 to move together through the connection part when it moves. When the driven slider 7 moves, the running wheel 10 will rub and walk on the outer frame surface of the photovoltaic curtain wall 1, driving the cloth rolling roller 8 to rotate and unwind the water-permeable cloth on it. As the driven slider 7 moves, it will adhere to the surface of the photovoltaic curtain wall 1, and the newly applied cleaning liquid will be coated between the water-permeable cloth and the photovoltaic curtain wall 1, so as to wet the hard and stubborn mud spots on the surface of the photovoltaic curtain wall 1, making it soft and mixed with the cleaning liquid, so as to prepare for the subsequent wiping and cleaning process;

[0035] It is worth mentioning that, because the temperature of the surface of the photovoltaic curtain wall 1 is relatively high under the sunlight, the cleaning liquid between the permeable cloths will be heated and generate steam, so that the hot water and hot steam can further make it easier to separate the stubborn mud spots from the photovoltaic curtain wall 1, and at the same time, it can also soften stubborn stains such as bird droppings, further providing assistance for the subsequent cleaning process;

[0036] After the above-mentioned soaking and softening process is completed, the electric slider 6 is controlled to move downward, and at the same time, the rotating tube 17 is also switched to the locked state. Therefore, when the electric slider 6 moves downward, the rotating tube 17 and the wiping roller 9 will wipe and clean the surface of the photovoltaic curtain wall 1, and at the same time, when the driven slider 7 moves downward, the cloth roller 8 will rotate and rewind, and the water-permeable cloth will be rewound until the electric slider 6 and the driven slider 7 are all moved to the folding plate 2, completing the cleaning process of the surface of the photovoltaic curtain wall 1;

[0037] Furthermore, the number of cleaning times can be controlled according to actual conditions to ensure the cleaning effect of the photovoltaic curtain wall 1 .

[0038] In one of the more preferred embodiments, an implementation of a connecting portion is provided, which can be specifically referred to in Figure 3 ;

[0039] The connecting part includes a fixing member 12 fixed to the outer wall of the driven slider 7. A slide groove 13 is provided on the outer wall of the fixing member 12. A slider 14 is slidably mounted on the inner wall of the slide groove 13. One end of the rotating tube 17 passes through the slider 14 and is rotatably connected to the penetration point of the slider 14.

[0040] As can be seen from the above content, the electric slider 6 drives the driven slider 7 to move through the connecting part, and the specific method is as follows:

[0041] When the electric slider 6 moves upward, it will first drive the slider 14 to move upward, until the slider 14 contacts the end of the slide groove 13, and then the driven slider 7 will be driven to slide upward together through the fixing member 12. Similarly, when the electric slider 6 moves downward, it will first drive the slider 14 to move downward, until the slider 14 contacts the bottom inner wall of the slide groove 13, and then the driven slider 7 will be driven to move downward together through the fixing member 12.

[0042] In this way, the electric slider 6 can drive the driven slider 7 to move together, and there will be a certain gap between the two, which provides space and time for the rotation state switching of the rotating tube 17 and the wiping roller 9.

[0043] In one of the more preferred embodiments, the cloth rolling roller 8 and the rotating tube 17 are both coaxially fixed with a gear 11, and the two gears 11 can mesh with or disengage from each other.

[0044] As can be seen from the previous content, during the upward movement of the electric slider 6, the distance between the electric slider 6 and the driven slider 7 is the largest, at which time the two gears 11 are in a disengaged state, and the rotation and unwinding of the cloth winding roller 8 will not limit or affect the rotation of the rotating tube 17 and the wiping roller 9, and the wiping roller 9 can rotate freely;

[0045] When the electric slider 6 moves downward, the distance between it and the driven slider 7 is the smallest. At this time, the two gears 11 are in a meshing state. At this time, the cloth winding roller 8 will drive the wiping roller 9 to rotate during the winding and rotation process, and the rotation direction of the wiping roller 9 is opposite to that of the cloth winding roller 8, so that the wiping roller 9 will be relatively displaced with the plane of the photovoltaic curtain wall 1, so that the wiping length of the wiping roller 9 is longer within the limited length range of the photovoltaic curtain wall 1, thereby further improving the wiping effect of the wiping roller 9, and the relative friction can also further improve the removal effect of the wiping roller 9 on stubborn mud spots, thereby improving the cleaning effect.

[0046] In this way, the rotation state of the cloth rolling roller 8 can be automatically switched by the meshing of the two gears 11, thereby reducing the need for setting other driving sources and requiring only the wiping roller 9 to be replaced regularly.

[0047] In one of the more preferred embodiments, an implementation of a water spraying part is provided, which can be specifically referred to in Figure 2 ;

[0048] The water spraying part includes a ring 15 which is fixed on the outer wall of the slider 14 and has the end of the rotating tube 17 sleeved therein. A drainage hole is provided on the inner wall of the rotating tube 17 which contacts the wiping roller 9, and a water inlet hole which is connected to the inside of the ring 15 is provided on the end of the rotating tube 17. A water tank 19 and a micro water pump 18 are fixedly installed inside the bracket keel 4. The water inlet pipe of the micro water pump 18 is connected to the water tank 19, and the water outlet pipe is connected to the inside of the ring 15.

[0049] During the upward movement of the electric slider 6, the micro water pump 18 draws the cleaning liquid in the water tank 19 into the rotating tube 17, and then discharges the cleaning liquid to the wiping roller 9 through the drainage hole of the rotating tube 17, so that the cleaning liquid can be coated on the surface of the photovoltaic curtain wall 1 as the wiping roller 9 rotates;

[0050] Then, when the electric slider 6 moves downward to wipe, the micro water pump 18 can stop pumping liquid and continue to complete the wiping process.

[0051] In one of the more preferred embodiments, a trigger switch 16 for controlling the start and stop of the micro water pump 18 is provided;

[0052] A trigger switch 16 for controlling the start and stop of the micro water pump 18 is installed on the inner wall of the slide groove 13 away from the driven slider 7.

[0053] For details, please refer to Figure 3As can be seen from the previous content, when the electric slider 6 moves up, the slider 14 contacts the upper inner wall of the slide groove 13. At this time, the slider 14 will contact the trigger switch 16, thereby controlling the micro water pump 18 to turn on. When the electric slider 6 moves down, the slider 14 will contact the lower inner wall of the slide groove 13, and the slider 14 and the trigger switch 16 will be disengaged. At this time, the micro water pump 18 will be turned off. In this way, the start and stop control of the micro water pump 18 can be automatically completed by the up and down movement of the electric slider 6.

[0054] In one of the more preferred embodiments, the folding plate 2 is rotatably installed at the bottom of the photovoltaic curtain wall 1 through a hinge, and the folding plate 2 can be rotated backward along the hinge to be folded.

[0055] By setting the folding plate 2, it can be rotated and folded backward along the hinge, and its upper structure is hidden to the back of the photovoltaic curtain wall 1, so that the surface of the photovoltaic curtain wall 1 can be made more beautiful. For details, please refer to Figure 5 Moreover, the unfolding of the folding plate 2 can be combined with the rotation of the photovoltaic curtain wall 1. After it rotates outward to provide space for the unfolding of the folding plate 2, it can be unfolded.

[0056] In one of the more preferred embodiments, the outer wall of the photovoltaic curtain wall 1 is provided with a friction edge that is in frictional contact with the running wheel 10 .

[0057] For details, please refer to Figure 3 By setting the friction edge, the friction between the running wheel 10 and the photovoltaic curtain wall 1 can be further improved to avoid slipping.

[0058] In one of the more preferred embodiments, the wiping roller 9 is a sponge roller or a brush roller, and preferably a sponge roller, which can make the cleaning liquid easy to seep out and wipe more comprehensively.

[0059] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
