[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figures 1-5 A thermoelectric integrated device for insulating glass used in photovoltaic curtain walls, comprising:

[0032] The outer frame 1 serves as the basic support structure for the entire device, providing a stable working environment for the internal components.

[0033] Photovoltaic thermoelectric module, the photovoltaic thermoelectric module is installed inside the outer frame 1.

[0034] The photovoltaic thermoelectric module includes a heat exchange plate 2, an inner EVA layer 4, a silicon photovoltaic cell 5, and an outer EVA layer 6, which are sequentially stacked and sealed together. The heat exchange plate 2 is close to the wall and has a heat pipe 3 installed inside. The heat pipe 3 is connected to the external heat exchange mechanism. Through the stacked and sealed design, the waste heat generated by the silicon photovoltaic cell 5 is quickly transferred to the heat exchange plate 2 through the inner EVA layer 4, and then discharged and utilized through the heat pipe 3, which greatly improves the heat recovery efficiency.

[0035] The EVA layer, or ethylene-vinyl acetate copolymer layer, is the core material for photovoltaic module encapsulation, possessing excellent light transmittance, adhesion, and weather resistance. The silicon photovoltaic cell module 5, composed of multiple monocrystalline or polycrystalline silicon cells connected in series or parallel, is the core component for converting solar energy into electrical energy.

[0036] A protective plate is fixedly connected to the side of the outer frame 1 closest to the wall. The protective plate is located between the heat exchange plate 2 and the wall and is used to protect the heat exchange plate 2.

[0037] The sealing sliding frame 7 is sealingly and slidingly connected to the inside of the outer frame 1, and the glass plate 10 is sealingly installed in the inside of the sealing sliding frame 7. The sealing sliding frame 7, the glass plate 10, the photovoltaic thermoelectric assembly and the outer frame 1 form a sealed hollow cavity 14. The outer EVA layer 6 away from the side of the silicon photocell group 5 forms the inner side wall of the hollow cavity 14. The outer frame 1 is fixedly connected with a plurality of telescopic rod mounting sleeves 12 in the inside. The micro electric telescopic rods 13 are mounted on the telescopic rod mounting sleeves 12. The output ends of the plurality of micro electric telescopic rods 13 are fixedly connected with the inside of the sealing sliding frame 7.

[0038] Referring to Figure 7 , the sealing sliding frame 7 is provided with a sealing groove 8 on the outside. The sealing groove 8 is fixedly connected with a sealing ring 9 in the inside. The sealing ring 9 is sealingly and slidingly matched with the inside of the outer frame 1. Through the cooperation of the sealing groove 8 and the sealing ring 9, the sealing reliability is improved. At the same time, the sealing groove 8 plays a fixing role on the sealing ring 9, reducing the sliding wear.

[0039] The glass plate 10 is coated with an anti-glare coating 11 on the outside. The cleaning brush 17 is slidingly matched with the outside of the anti-glare coating 11. The anti-glare coating 11 is made of weather-resistant and wear-resistant material. It can be used for a long time with the cleaning brush 17 while reducing glare, keeping the coating performance stable.

[0040] The controller is used to receive the signals of the sensors and control the working states of the plurality of micro electric telescopic rods 13.

[0041] The temperature and humidity sensor 24 and the pressure sensor 25 are installed in the inside of the hollow cavity 14. The micro electric telescopic rods 13, the temperature and humidity sensor 24 and the pressure sensor 25 are electrically connected with the controller. The controller is installed in the inside of the outer frame 1. The sensors and the controller are integrated in the inside of the device, realizing real-time monitoring and precise control, while reducing the influence of the external environment.

[0042] Referring to Figure 6 and Figure 7 , the cleaning mechanism includes two vertical sliding rails 15 fixedly connected to the outside of the sealing sliding frame 7. The two vertical sliding rails 15 are slidingly connected with sliding frames 16. The same cleaning brush 17 is fixedly connected between the two sliding frames 16. The cleaning brush 17 is slidingly matched with the outside of the glass plate 10.

[0043] A vertical slide rail 15 top is provided with a stepping motor, the output end of the stepping motor is fixedly connected with a lead screw 18, the lead screw 18 is rotatably connected to the vertical slide rail 15, another vertical slide rail 15 is rotatably connected with a slide rod 19, one sliding frame 16 is threadedly connected with the lead screw 18, and the other sliding frame 16 is slidably connected with the slide rod 19, the stepping motor is electrically connected with a controller, and the controller is used for controlling the stepping motor to work, so that the sliding frame 16 reciprocates along the lead screw 18 in the stroke range of the vertical slide rail 15, and the single movement interval is the interval of adjacent units in the silicon photocell group 5; when the light is at different angles, the cleaning brush 17 is located at the interval of adjacent units in the silicon photocell group 5, so as to avoid affecting the silicon photocell group 5.

[0044] Through the cooperation of the stepping motor and the lead screw 18, precise displacement control is realized, the unit interval of the silicon photocell group 5 is adapted, and dead angle cleaning is ensured.

[0045] The outer frame 1 at the heat exchange plate 2 is fixedly connected with a drying box 20, and a heat conducting plate is fixedly connected between the heat exchange plate 2 and the drying box 20, so as to improve the heating effect of the heat exchange plate 2 on the drying box 20.

[0046] The drying box 20 contains molecular sieve drying agent, and the drying box 20 is in communication with the hollow cavity 14 through a gas inlet pipe 21 and is in communication with the outside through a gas outlet pipe 22, and the gas inlet pipe 21 and the gas outlet pipe 22 are both provided with electric valves 23, and the electric valves 23 are electrically connected with a controller, and the controller is used for controlling the two electric valves 23 to open and close alternately when the hollow cavity 14 is in an expanded state, so as to realize the regeneration of the drying agent.

[0047] Through the cooperation of the drying box 20 and the two electric valves 23, the regeneration of the drying agent is realized under the expansion pressure of the hollow cavity 14, the loss of nitrogen gas in the hollow cavity 14 is reduced, the drying agent does not need to be replaced frequently, and the maintenance cost is reduced.

[0048] A gas replacement connector 26 is in communication with one side of the hollow cavity 14, a one-way valve is installed in the gas replacement connector 26, and a sealing plug 27 is threadedly and sealingly installed at an end away from the hollow cavity 14, and the gas replacement connector 26 is in communication with an external nitrogen source, and is used for filling nitrogen into the hollow cavity 14.

[0049] By filling nitrogen into the hollow cavity 14 through the gas replacement connector 26, the thermal conductivity is reduced, and the heat preservation performance is improved; at the same time, through the cooperation of the one-way valve and the sealing plug 27, the inside of the hollow cavity 14 is ensured to be sealed after gas replacement, and nitrogen can be conveniently supplemented during later maintenance, without the need to replace the corresponding parts as a whole.

[0050] When the application is used, sunlight passes through the outer glass plate 10 and the anti-glare coating 11, and irradiates the outer EVA layer 6 of the photovoltaic thermoelectric module. Then the light is transmitted to the silicon photocell group 5 through the outer EVA layer 6. After the silicon photocell group 5 absorbs light energy, the solar energy is converted into electrical energy through the photoelectric effect. The electrical energy is transmitted to the building power grid or energy storage equipment through the corresponding external components to meet the building electricity demand.

[0051] When the silicon photocell group 5 works, it will generate waste heat. This part of heat is quickly transmitted to the heat exchange plate 2 through the inner EVA layer 4. The heat is conducted out by the heat conduction pipe 3 inside the heat exchange plate 2. On the one hand, it can be transmitted to the heating or hot water system inside the building to realize waste heat heating. On the other hand, it can be matched with a thermoelectric power generation module to further generate electricity by utilizing the temperature difference between the heat exchange plate 2 and the external environment, thereby improving the energy utilization rate. During the whole process, the side of the outer EVA layer 6 away from the silicon photocell group 5 forms the inner side wall of the hollow cavity 14. The existence of the hollow cavity 14 can reduce the heat loss to the outside, thereby ensuring the thermoelectric conversion efficiency.

[0052] When the outdoor temperature rises (such as at noon in summer), the nitrogen gas in the hollow cavity 14 expands due to heating. When the pressure sensor 25 detects that the pressure inside the hollow cavity 14 reaches the upper threshold value, it transmits a signal to the controller. The controller instructs the output ends of multiple micro electric telescopic rods 13 to extend synchronously, thereby pushing the sealing sliding frame 7 to slide along the inner side of the outer frame 1. The volume of the hollow cavity 14 increases, thereby offsetting the pressure rise caused by gas expansion. At the same time, the enlarged hollow cavity 14 can enhance the heat insulation effect and reduce the transmission of high temperature from the outside to the silicon photocell group 5.

[0053] When the temperature decreases (such as at night or in winter), the gas in the hollow cavity 14 contracts, and the pressure is lower than the lower threshold value. When this happens, the controller instructs the output ends of the micro electric telescopic rods 13 to retract, thereby pulling the sealing sliding frame 7 to slide reversely. The volume of the hollow cavity 14 decreases, thereby avoiding the formation of negative pressure that causes external moisture to penetrate. During this process, the reduced hollow cavity 14 can improve the heat conduction efficiency, making it easier for the waste heat of the heat exchange plate 2 to be transmitted to the inside of the building, thereby reducing heat waste. During the whole adjustment process, the controller always ensures that the minimum value and the maximum value of the expansion and contraction of the hollow cavity 14 match the temperature, thereby maintaining the stable air pressure of the hollow cavity 14.

[0054] When the controller detects that the power generation of the silicon photocell group 5 is lower than the historical standard of the same period and reaches a certain threshold value, it is determined that the dust accumulation has an impact, or the preset cleaning time is reached, and the cleaning process is started.

[0055] The controller instructs the step motor at the top of the vertical sliding rail 15 to start. The step motor drives the screw rod 18 to rotate. One sliding frame 16 is threadedly connected with the screw rod 18, and the other sliding frame 16 is slidingly connected with the sliding rod 19. Therefore, when the screw rod 18 rotates, the two sliding frames 16 drive the cleaning brush 17 to move along the vertical sliding rail 15 stably.

[0056] The cleaning brush 17 is in sliding fit with the anti-glare coating 11 outside the glass plate 10, and the fixed number of turns of the stepping motor is rotated each time, and the single movement distance of the sliding frame 16 is just equal to the distance between adjacent units in the silicon photocell group 5, so that the cleaning is ensured to be without missing and repetition, and the sliding frame 16 is always located in the gap between adjacent units in the silicon photocell group 5, without hindering the working of the silicon photocell group 5, and after the cleaning is completed, the controller instructs the stepping motor to reverse, so as to drive the sliding frame 16 to reset, and wait for the next cleaning instruction.

[0057] When the temperature and humidity sensor 24 detects that the humidity inside the hollow cavity 14 exceeds the predetermined threshold value, the controller starts the desiccant regeneration process, first controls the expansion and stabilization of the hollow cavity 14, so that the pressure inside the hollow cavity 14 is reduced, and a small pressure difference is formed between the desiccant box 20 and the hollow cavity 14, thereby reducing the nitrogen gas inside the desiccant box 20 and reducing the loss of nitrogen gas in the desiccant regeneration process.

[0058] When the hollow cavity 14 is in the expanded state, first, the electric valve 23 of the air inlet pipe 21 is closed, and the electric valve 23 of the exhaust pipe 22 is opened. At this time, the molecular sieve desiccant in the desiccant box 20 can absorb the waste heat generated by the operation of the photovoltaic thermoelectric assembly due to the proximity of the heat exchange plate 2, and the temperature rise causes the water absorbed by the desiccant to evaporate into water vapor. The water vapor is discharged to the outside through the exhaust pipe 22, and the moisture release is completed. Then, the valve electric valve 23 on the exhaust pipe 22 is closed, and the electric valve 23 of the air inlet pipe 21 is opened. The dry nitrogen inside the hollow cavity 14 is recharged to the desiccant box 20, and the desiccant regeneration is completed without manual replacement.

[0059] After long-term operation, if the pressure sensor 25 detects that the air pressure inside the hollow cavity 14 is insufficient, it is judged that the nitrogen concentration has decreased. The sealing plug 27 is unscrewed, the external nitrogen source is connected to the gas replacement joint 26, the one-way valve inside the gas replacement joint 26 prevents reverse leakage of nitrogen, and nitrogen is filled into the hollow cavity 14 until the pressure is restored. After the nitrogen source is closed and the sealing plug 27 is screwed back, the hollow cavity 14 is always filled with nitrogen with low thermal conductivity, which maintains the heat preservation and sealing performance.

[0060] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent substitutions or changes within the technical scope disclosed by the present application and according to the technical solutions and inventive concepts of the present application, which should be covered within the protection scope of the present application.
