TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic curtain wall, in particular to an energy-saving building photovoltaic curtain wall. BACKGROUND

[0002] The photovoltaic curtain wall, also known as the photoelectric curtain wall, mainly uses the photovoltaic cell and the photoelectric panel technology to convert the sunlight into the electric energy, and then stores the electric energy for the emergency power supply of the residential building or the office building. Since the photovoltaic curtain wall can convert the inexhaustible solar energy into the directly usable electric energy without pollution during the operation, the photovoltaic curtain wall has high application value in the design of the building outer wall.

[0003] The existing application No. CN201820481005.4 discloses an energy-saving building photovoltaic curtain wall which can rotate with the sun. The technical scheme of the energy-saving building photovoltaic curtain wall comprises a mounting frame, a support rod fixed on the mounting frame, a photovoltaic panel hingedly connected to the other end of the support rod, a swing rod mechanism for driving the photovoltaic panel to reciprocatingly tilt, the other end of the swing rod mechanism being hingedly connected to the photovoltaic panel, a cam driving mechanism for driving the swing rod mechanism to act, and the cam driving mechanism being hingedly connected to the swing rod mechanism. The energy-saving building photovoltaic curtain wall can rotate with the sun to improve the light energy utilization rate, and solves the problem that the existing photovoltaic curtain wall can absorb less light energy.

[0004] The existing photovoltaic curtain wall can adjust the angle to strengthen the light energy absorption effect. However, the back plate of the existing photovoltaic curtain wall has a high temperature during the use, which can easily affect the indoor temperature. In addition, the back plate temperature lacks a certain waste heat recovery measure to improve the adaptability. In addition, the photovoltaic building curtain wall is easily affected by rainwater erosion, dust accumulation and other factors during the long-term use, which can cause dirt on the surface of the photovoltaic curtain wall. The accumulation of the dirt can reduce the light transmittance of the photovoltaic panel, and further affect the power generation efficiency. At present, the traditional way is to use a hanging rope, a hanging plate and other tools to suspend the cleaning personnel to the surface of the photovoltaic curtain wall for cleaning.

[0016] Compared with the prior art, the present application has the following advantages:

[0017] The application sets up a photovoltaic glass structure, that is, through the combination of intelligent light-adjusting glass, aerogel heat insulation layer, light-transmitting photovoltaic glass and back plate, high-efficiency heat insulation and energy-saving effect can be met, building heat loss is greatly reduced, the light-adjusting blocking ability of the intelligent light-adjusting glass is matched, equipment load and energy consumption are significantly reduced, and a waste heat recovery cleaning device is set up, that is, a heat collecting cavity can be formed between the partition plate and the back plate to accumulate waste heat, through the linkage cooperation of the internal air extraction structure, the moving structure, the gas conveying structure and the cleaning roller group of the air extraction cleaning assembly, the hot air can be discharged to the outside of the light-transmitting photovoltaic glass again to recover waste heat and brush and blow clean the dust attached to the outside of the light-transmitting photovoltaic glass, so that the light-transmitting energy collecting effect is ensured.

[0018] The partition plate, the supporting pad and the heat collecting cavity are set up, that is, the partition plate can form a heat collecting cavity with the back plate through the supporting pad arranged on one side, through the action of the heat collecting cavity, the heat emitted by the back plate can be collected to avoid being directly introduced into the room to cause the indoor temperature to rise.

[0019] The air extraction structure is set up, that is, when the fan arranged in the connecting box is running, the transmission end of the fan can be connected with the rotating rod, when the rotating rod rotates, the linkage operation of the transmission structure can be realized, the rotating rod can drive the fan blades arranged at the lower end of the air extraction pipe to rotate, in this way, the fan blades can make the air extraction pipe have the suction capacity to transmit the hot air in the heat collecting cavity to the inside of the connecting box, through the blowing assistance of the fan, the hot air can be transmitted to the inside of the gas conveying structure to ensure the subsequent waste heat recovery effect, at the same time, the rotating rod can also drive the first bevel gear connected with the other side to make the first bevel gear mesh with the second bevel gear connected with the outer end, in this way, through the second bevel gear, the operation of the moving structure can be realized to make it meet the subsequent left-right reciprocating movement and brushing cleaning activities.

[0020] The moving structure is set up, that is, when the second bevel gear rotates, the rotation of the roller can be realized, the transmission groove arranged on the outside of the roller can be in transmission with the sliding block arranged at the upper end of the connecting frame during the rotation process, so that the connecting frame can move left and right along the outside of the roller, in this way, the cleaning roller group connected with the upper end of the connecting frame can realize the left-right reciprocating brushing cleaning activities.

[0021] The air supply structure is designed so that hot air entering the connecting box can be blown into the air supply pipe by a fan, and then transported into the cleaning roller assembly through the air supply pipe. This ensures that the hot air can be discharged back to the outside of the transparent photovoltaic glass, thus ensuring the recovery and utilization of waste heat. At the same time, when the cleaning roller assembly moves back and forth with the connecting frame, the air supply pipe can be pulled synchronously. The air supply pipe can be stabilized by externally abutting rollers. Furthermore, the rollers can move laterally synchronously by being pulled by the air supply pipe. With the docking combination of the limiting block and the limiting rod, its lateral movement stability is ensured. Meanwhile, the spring located on one side of the limiting rod can be compressed when the limiting block moves laterally. The spring force not only strengthens the tightness between the roller and the outside of the air supply pipe, but also provides a rebound assist effect during subsequent reset.

[0022] The cleaning roller assembly is designed so that the connecting frame allows for lateral movement of the bottom cylinder and the air supply cylinder. This allows the brush strips on one side of the air supply cylinder to effectively clean dust adhering to the exterior of the translucent photovoltaic glass. Simultaneously, the hot air, transmitted through the air supply pipe, enters the air supply cylinder and is discharged to the exterior of the translucent photovoltaic glass through the exhaust port for heat recovery and dust removal. Furthermore, the hot air entering the bottom cylinder causes the impeller inside to rotate. The connecting rod mounted on the upper end of the impeller allows the rotation of the upper external limiting cam. As the cam rotates, it moves upward via the upper body of the rod on the upper right side of the first bracket, causing the cam to synchronously push against the fixed shaft on the upper right side. This intermittent upward movement of the fixed shaft against the second bracket allows the air supply cylinder, fitted onto the upper end of the bottom cylinder, to move intermittently up and down. This ensures that the exhaust port and brush strips can perform not only lateral reciprocating air and brushing but also vertical reciprocating air and brushing, significantly enhancing the cleaning range and effectiveness.

[0041] The transmission structure 5414 comprises a belt pulley set 54141, the lower end of the belt pulley set 54141 is connected with the rotating rod 5418, the upper end of the belt pulley set 54141 is connected with a first rotating disc 54142, that is, the belt pulley set 54141 can realize the same direction rotation of the first rotating disc 54142, three connecting rods 54143 are movably inserted into the inside of the first rotating disc 54142, the three connecting rods 54143 are all arranged in the shape of a right angle rod, the upper ends of the three connecting rods 54143 are movably inserted into the inside of a second rotating disc 54144, the upper end of the second rotating disc 54144 is vertically provided with a vertical rod 54145, the second rotating disc 54144 is rotatably clamped on the left side of a connecting frame 54146 to ensure the stability of the right angle rotation transmission state, the upper end of the connecting frame 54146 is fixedly connected with the inside of the connecting box 5411, and the top of the vertical rod 54145 is connected with the fan blade 5415.

[0042] The moving structure 542 comprises a roller 5421 transversely arranged at the lower end of the front side of the frame 1, and the left side of the roller 5421 is connected to the middle part of the second bevel gear 54110. The roller 5421 is externally provided with a transmission groove 5422, and the transmission groove 5422 is oppositely and transversely arranged. The roller 5421 is externally provided with a connecting frame 5423, and the connecting frame 5423 is internally and upwardly provided with a sliding block 5424. The bottom of the sliding block 5424 is embedded in the transmission groove 5422. When the transmission groove 5422 rotates with the roller 5421, the sliding block 5424 can transversely and reciprocally move, so as to ensure the linkage of the subsequent reciprocating transverse brushing cleaning effect. The upper end of the connecting frame 5423 is connected to the cleaning roller group 544.

[0043] Specifically, the back plate 24 and the partition plate 51 form a heat collecting cavity 53 by arranging the partition plate 51 at the rear side of the frame 1 and arranging a plurality of supporting pads 52 on one side. The heat collecting cavity 53 can pre-concentrate the heat emitted by the back plate 24, avoiding direct introduction into the room. The fan 5413 installed in the connecting box 5411 can perform air suction assistance. When the fan 5413 rotates, the rotating rod 5418 connected to one side can rotate. When the rotating rod 5418 rotates, the pulley set 54141 connected to the outside can synchronously rotate. In this way, the first rotating disc 54142 connected to the upper left side can rotate. When the first rotating disc 54142 rotates, the three connecting rods 54143 in the form of straight rods and movably arranged in the first rotating disc 54142 can rotate and perform self-expansion. In this way, the second rotating disc 54144 connected to the upper end of the three connecting rods 54143 can synchronously rotate through rotation and self-expansion and be in a stable rotating state by being connected to the connecting frame 54146. In this way, the vertical rod 54145 vertically arranged at the middle part of the upper end of the second rotating disc 54144 can rotate with the top connected fan blade 5415, so that the fan blade 5415 has a certain suction force. In this way, the hot air collected in the heat collecting cavity 53 can be sucked into the connecting box 5411 through the suction pipe 5416 and be transmitted to the air conveying structure 543 through the blowing of the fan 5413, so as to export the hot air and make it contact with the photovoltaic glass structure 2 again to recover heat. When the rotating rod 5418 rotates, the first bevel gear 5419 connected to the left side can also rotate. In this way, the first bevel gear 5419 can rotate with the second bevel gear 54110 engaged with the outside, so that the moving structure 542 connected to the middle part of the second bevel gear 54110 can be linked and operated, so as to realize the use of waste heat and avoid resource waste.

[0044] Secondly, when the second bevel gear 54110 rotates, the roller 5421 connected to the middle part will rotate accordingly. Thus, the transmission groove 5422 opened on the outer part of the roller 5421 will rotate synchronously. In this way, the slider 5424 arranged on the upper end of the connecting frame 5423 is driven to rotate and guide the slider 5424 through the transmission groove 5422, so as to meet the horizontal reciprocating movement of the connecting frame 5423. Thus, the cleaning roller group 544 connected to the upper end of the connecting frame 5423 can move left and right reciprocally to meet the scraping and cleaning of the dust attached to the outer part of the light-transmitting photovoltaic glass 23, reduce the dust attachment, and improve the light transmittance.

The gas inlet end of the gas conveying pipe 5431 is connected to the connecting box 5411, and the gas outlet end of the gas conveying pipe 5431 is connected to the cleaning roller group 544. The outer part of the gas conveying pipe 5431 is in contact with the outer side of the roller 5432. The upper and lower ends of the roller 5432 are provided with limiting plates 5433, and the limiting plates 5433 are embedded in the inner part of the lower end of the frame 1. Thus, the installation position of the roller 5432 can be limited. The inner part of each limiting plate 5433 is inserted with two limiting rods 5434. The two ends of the limiting rods 5434 are connected to the inner part of the lower end of the frame 1. The outer end of each limiting rod 5434 is provided with a spring 5435, and one end of the spring 5435 is connected to the side of the limiting plate 5433. Thus, when the gas outlet end of the gas conveying pipe 5431 moves with the horizontal cleaning activity, the roller 5432 can be pulled. The roller 5432 can be guided by the limiting plate 5433 and the limiting rod 5434 and supported by the spring 5435, so as to ensure that the gas conveying pipe 5431 can adapt to the horizontal cleaning activity and ensure the stable gas conveying process.

[0046] The gas conveying structure 543 is arranged in the lower end of the frame 1, and the gas conveying pipe 5431 is arranged in a flexible tubular shape. Thus, the stable gas conveying process can be ensured, and the blockage problem can be avoided.

[0047] Specifically, the hot air drawn into the inside of the connection box 5411 from the air extraction pipe 5416 can be transmitted to the inside of the gas transmission pipe 5431 by the blowing assistance of the fan 5413, and the transmission through the gas transmission pipe 5431 can transmit the hot air to the inside of the cleaning roller group 544 to perform the hot air blowing waste heat recovery activity, and when the cleaning roller group 544 moves left and right with the connection frame 5423, the gas exhaust end of the gas transmission pipe 5431 abutting to the lower end side of the cleaning roller group 544 will be synchronized to move horizontally, and in the process of moving left, the gas transmission pipe 5431 will be pulled as a whole, and because the outside of the gas transmission pipe 5431 abuts against the roller 5432, the roller 5432 can not only be guided to roll, but also can be synchronized to move left by the pulling effect, and in cooperation with the limiting plate 5433 arranged at the upper and lower ends, the stability of the roller 5432 during horizontal movement can be ensured, and the limiting plate 5433 can be further guided to move horizontally by the limiting rod 5434 inserted in the inside to further enhance the stability of horizontal movement, and when the limiting plate 5433 moves left, the spring 5435 arranged outside the limiting rod 5434 can be extruded, so that the roller 5432 can be tightly attached to the outside of the gas transmission pipe 5431, and in the subsequent right-moving reset process of the roller 5432, in cooperation with the rebound effect of the spring 5435, the automatic right-moving reset can be realized, so as to ensure the stability of the hot air transmission process, so that it can adapt to the left-right reciprocating movement of the cleaning roller group 544.

[0048] Please refer to Figures 9-10 The cleaning roller group 544 in the embodiment includes a bottom cylinder 5441 installed on the upper end of the connection frame 5423, and the bottom cylinder 5441 is connected with the gas exhaust end of the gas transmission pipe 5431, the upper end of the bottom cylinder 5441 is telescopically sleeved with a gas transmission cylinder 5442, the gas transmission cylinder 5442 is respectively provided with an exhaust port 5443 and a brush strip 5444 opposite to one side of the photovoltaic glass structure 2, and the exhaust port 5443 and the brush strip 5444 are alternately arranged along the outside of the gas transmission cylinder 5442, the inside of the bottom cylinder 5441 is provided with a jacking structure 5445, and the top of the jacking structure 5445 is connected with the gas transmission cylinder 5442.

[0049] The jacking structure 5445 includes an impeller 54451 installed at the lower end of the bottom cylinder 5441, and the impeller 54451 is opposite to the exhaust position of the gas conveying pipe 5431, that is, when the hot gas enters the inside of the bottom cylinder 5441, the impeller 54451 can be blown to rotate, meeting the subsequent jacking driving activity, and the upper end of the impeller 54451 is vertically installed with a butt joint rod 54452, and the first support 54453 is installed on the outer side of the upper end of the butt joint rod 54452, and the rod body is fixedly connected to the right upper end of the first support 54453, and the rod body provided at the right upper end of the first support 54453 abuts against the bottom of the cam 54454, and the cam 54454 is limitingly sleeved on the outer side of the upper end of the butt joint rod 54452, that is, when the butt joint rod 54452 rotates, the cam 54454 can be synchronously driven to rotate, and at the same time, the guiding and limiting activities can be realized when the cam 54454 moves up and down, the right side of the upper end of the cam 54454 abuts against the fixed shaft 54455, the upper end of the fixed shaft 54455 is connected with the second support 54456, and the second support 54456 is fixedly connected with the inside of the gas conveying cylinder 5442.

[0050] The upper and lower surfaces of the cam 54454 are both provided in an inclined surface shape, and the upper and lower inclined surfaces of the cam 54454 respectively abut against the right side of the upper end of the first support 54453 and the lower end of the fixed shaft 54455, that is, the cam 54454 cooperates to realize the transmission effect of the inclined surfaces and the rod body and the fixed shaft 54455, meeting the rotary jacking activity, and ensuring that the cleaning roller group 544 as a whole can realize the up-and-down brushing and blowing activities.

[0051] Specifically, the hot gas can be transmitted to the inside of the bottom cylinder 5441 through the gas conveying pipe 5431, and then transmitted to the inside of the gas conveying cylinder 5442 along the bottom cylinder 5441, and the hot gas entering the inside of the gas conveying cylinder 5442 will be discharged through the exhaust port 5443 provided on one side of the outside of the gas conveying cylinder 5442, so that the hot gas is discharged to the outside of the light-transmitting photovoltaic glass 23 again, ensuring that the hot gas can be used for waste heat recovery through the light-transmitting photovoltaic glass 23;

[0052] When the connecting frame 5423 moves left and right reciprocatingly, the bottom cylinder 5441 butt-jointed to the upper end of the connecting frame 5423 can realize the synchronous left and right reciprocating movement of the gas conveying cylinder 5442, so that the brush strip 5444 provided on one side of the outside of the gas conveying cylinder 5442 brushes the outside of the light-transmitting photovoltaic glass 23, so that the dust attached to the outside of the light-transmitting photovoltaic glass 23 is quickly brushed and cleaned, and the discharged hot gas can also realize dust blowing assistance, thereby enhancing the cleaning effect and ensuring the light-transmitting light energy recovery effect of the light-transmitting photovoltaic glass 23;

[0053] Meanwhile, when the hot air is transmitted to the inside of the bottom cylinder 5441 through the gas conveying pipe 5431, the impeller 54451 installed at the lower end of the bottom cylinder 5441 will rotate by the blowing of the hot air, so that the connecting rod 54452 connected to the upper end of the impeller 54451 will rotate synchronously to realize the rotation of the cam 54454 sleeved on the upper end of the connecting rod 54452. When the cam 54454 rotates, the bottom of the cam 54454 can abut against the rod body arranged at the upper end of the right side of the first support 54453, so that the cam 54454 can move upward and lift. When the cam 54454 moves upward and rotates, the fixed shaft 54455 abutting against the right side of the upper end of the cam 54454 can realize the intermittent upward lifting of the second support 54456. Thus, the gas conveying cylinder 5442 sleeved on the upper end of the bottom cylinder 5441 can move upward intermittently, so that the exhaust port 5443 arranged on one side of the gas conveying cylinder 5442 and the brush strip 5444 can move up and down synchronously to realize the left-right reciprocating brushing and blowing of the brush strip 5444 and the up-down reciprocating movement of the brush strip 5444, so as to enhance the brushing and blowing effect of the brush strip 5444 and ensure the cleaning efficiency of the transparent photovoltaic glass 23.
