Description

Technical Field

[0001] The present invention relates to the technical field of solar collector devices, and specifically to a solar photovoltaic flat collector. Background Art

[0002] To facilitate the conversion of solar energy into heat energy, solar collector devices are often used. The invention patent with the patent application number CN201810504080.2 discloses a solar collector. To achieve the purposes of simple structure, easy production, low cost, and high light-to-heat conversion rate, it uses ordinary transparent hollow plastic plates, new hollow plastic plates, and solar heat collection plate frame profiles to make a multifunctional solar collector. It uses the hollow part of the hollow plastic plate as a pipeline to circulate air and water. Under the irradiation of sunlight, it absorbs the light energy of the sun's rays and converts it into heat energy to heat the air and water, providing warm air for the room and hot water for people's daily life. The angle of the heat collection box can be adjusted in multiple directions, and the volume of the heat collection box can be adjusted. When the sunlight is weak, the thickness of the heat collection box can be made smaller, making it easier to heat the water in the heat collection box. The invention patent with the patent application number CN202211277766.5 discloses a pressure relief plugging device for a mine explosion-proof door, including a concentrator, a collector, and a heat insulation box. The concentrator is provided with an outer lens and an inner lens, the diameter of the outer lens is larger than that of the inner lens, the heat insulation box is provided with a lens port, the diameter of the lens port is smaller than that of the outer lens, the collector is arranged in the heat insulation box, the collector receives the sunlight entering through the concentrator, and uses a heat insulation box provided with heat insulation materials to receive sunlight from the lens port, closing the contact between the collector and the outside air and reducing the heat dissipation area, which can effectively avoid the heat loss of the heat collection device. The concentrator and the heat insulation box are connected by a sphere, which can realize the tracking adjustment of sunlight. According to the disclosed technical solution, when the existing solar collector device is in use, on the one hand, it cannot effectively ensure the control of the outflow temperature of the heat conduction medium in the collector, and it is easy to have a high temperature when the sunlight is strong and a low temperature when the sunlight is insufficient, which is not conducive to ensuring the stability of the temperature control of the heat conduction medium; on the other hand, when the power of the heat generated by the collector decreases, it often cannot effectively ensure the stability of the water outlet temperature, and thus is not conducive to ensuring the constant temperature supply of hot water; on the other hand, it cannot adjust the temperature of the industrial hot water as needed, and thus is not conducive to the hot water supply work as needed.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When the solar photovoltaic flat plate collector is in use, the water pump one pumps the heat conduction medium in the heat exchange cylinder into the main pipe. The heat conduction medium flows in the main pipe, and part of the heat conduction medium enters the auxiliary pipe and then returns to the main pipe again. The heat converted from solar energy in the flat plate collector is absorbed through the main pipe and the auxiliary pipe, which can effectively utilize the auxiliary pipe to improve the heat absorption efficiency. At the same time, the heat conduction media in the main pipe and the auxiliary pipe are continuously mixed to ensure uniform heat absorption. The heat conduction medium enters the connecting sleeve, causing the air in the sliding sleeve to expand. The expanded air pushes the sliding rod, enabling the sliding sleeve to drive the clamping plate to move left and right through the temperature of the heat conduction medium. Furthermore, the clamping plate squeezes the button one to the left or right. The button one controls the electric valve to adjust the opening degree of the connecting pipe. When the power of the heat converted in the flat plate collector is relatively large, the flow rate of the heat conduction medium becomes faster. When the power of the heat converted in the flat plate collector is relatively small, the flow rate of the heat conduction medium becomes slower. The heat exchange work is carried out by using heat conduction media with different flow rates instead of heat conduction media with different temperatures, thereby effectively ensuring the stability of the temperature of the heat conduction medium, and facilitating the control of the temperature of the hot water, so as to improve the sufficient heat exchange temperature even when the solar energy is weak.

[0016] 2. When this solar photovoltaic flat plate collector is in use, cold water enters the heat exchange cylinder through a conduit. The heat conduction medium flows back and forth downward under the diversion of the partition in the heat exchange cylinder. The cold water flows spirally upward in the conduit and is pumped out by water pump two. If the temperature of the outflowing water is insufficient, the expansion rate of the air in the air sleeve is relatively low, and then the piston presses the button two downward through the push plate. Button two turns on the motor, and the motor drives the gate plate to rotate upward inside the gate sleeve through the meshing of the gear and the tooth pattern, closing or even shutting down the outlet pipe, and opening or even fully opening the return pipe, so that the water flows back to the inside of the conduit again through the return pipe and the branch pipe, and is heated again by the heat conduction medium in the heat exchange cylinder. At the same time, the power of water pump two is adjusted downward through the frequency converter to reduce the water flow rate to ensure that the water can be fully heated. The fully heated water causes the air in the air sleeve to expand, pushing the piston upward, and then the push plate presses the button two upward, and then the gate plate rotates downward, and the power of water pump two is increased to send out the hot water at an appropriate temperature outward. The temperature change of the hot water is avoided through the return pipe and the branch pipe until the heat of the heat conduction medium can completely heat the cold water to the required water temperature, then the return pipe is completely closed, and the power of water pump two is gradually increased to increase the heat output and improve the heat utilization rate.

[0017] 3. When this solar photovoltaic flat plate collector is in use, according to the usage requirements, turn the screw rod. The screw rod moves up and down at the top of the air sleeve through the thread, and drives the movable block to move up and down inside the air sleeve through the bearing, effectively adjusting the height of button two, so that the piston can press button two through the push plate at the corresponding temperature, and then the water temperature flowing out of the outlet pipe can be adjusted according to the needs, and the calibration work is carried out according to the thermometer on the outlet pipe, and then the output water temperature can be adjusted according to the usage requirements, improving the adaptability of the equipment.

The button two 27 is connected to the motor 22 and the frequency converter 29 through wires. The frequency converter 29 is connected to the water pump two 15 through wires. According to the usage requirements, the screw rod 28 is rotated. The screw rod 28 moves up and down on the top of the gas sleeve 23 through threads and drives the movable block 26 to move up and down inside the gas sleeve 23 through the bearing, thereby effectively adjusting the height of the button two 27, enabling the piston 24 to squeeze the button two 27 through the push plate 25 at the corresponding temperature, thereby being able to adjust the water temperature flowing out of the outlet pipe 17 as needed, and carrying out calibration work according to the thermometer on the outlet pipe 17, and being able to adjust the output water temperature according to the usage requirements, improving the adaptability of the equipment.

[0028] In this embodiment, one end of the conduit 14 is installed on the outer side of the bottom of the heat exchange cylinder 2, and the other end of the conduit 14 extends to the inner side of the heat exchange cylinder 2, spirally winds around the inner side of the heat exchange cylinder 2, and is then welded to the inner wall of the top of the heat exchange cylinder 2. The second water pump 15 is installed on the top of one side of the heat exchange cylinder 2 by bolts, and the second water pump 15 is communicated with the other end of the conduit 14. The top end of the return pipe 16 is welded to the bottom of the second water pump 15, and the bottom end of the return pipe 16 is welded to the top of one end of the conduit 14. One end of the branch pipe 30 is welded to the return pipe 16, and the other end of the branch pipe 30 passes through the outer side of the heat exchange cylinder 2 and is welded to the conduit 14. The return pipe 16 is communicated with the conduit 14 through the branch pipe 30. The branch pipes 30 are evenly distributed on the return pipe 16. One side of the top end of the return pipe 16 is welded with an outlet pipe 17, and a thermometer is installed on the outlet pipe 17. Both ends of the gate sleeve 18 are respectively welded to the outer sides of the return pipe 16 and the outlet pipe 17. The gate plate 19 is stuck inside the gate sleeve 18. Both ends of the gate plate 19 respectively extend to the inner sides of the return pipe 16 and the outlet pipe 17. A tooth pattern 20 is formed on one side of the gate plate 19. The gear 21 is installed inside the gate sleeve 18, and the gear 21 meshes with the tooth pattern 20. The motor 22 is installed on the outer side of the gate sleeve 18 by bolts. The output shaft of the motor 22 extends to the inside of the gate sleeve 18 and is key-connected to the gear 21. During use, cold water enters the heat exchange cylinder 2 through the conduit 14. The heat-conducting medium flows back and forth downward under the diversion of the partition plate 13 inside the heat exchange cylinder 2. The cold water spirally flows upward inside the conduit 14 and is pumped out by the second water pump 15. If the temperature of the outflowing water is insufficient, the expansion rate of the air inside the air sleeve 23 is relatively low. As a result, the piston 24 presses the button two 27 downward through the push plate 25. The button two 27 turns on the motor 22. The motor 22 drives the gate plate 19 to rotate upward inside the gate sleeve 18 through the meshing of the gear 21 and the tooth pattern 20, closes or even shuts down the outlet pipe 17, and opens or even fully opens the return pipe 16, so that the water flows back into the inner side of the conduit 14 again through the return pipe 16 and the branch pipes 30, and is heated again by the heat-conducting medium inside the heat exchange cylinder 2. At the same time, the power of the second water pump 15 is reduced by the frequency converter 29 to reduce the water flow rate to ensure that the water can be fully heated. The fully heated water causes the air inside the air sleeve 23 to expand, pushes the piston 24 upward, and then the push plate 25 presses the button two 27 upward, so that the gate plate 19 rotates downward and the power of the second water pump 15 is increased to send out the hot water at an appropriate temperature outward. The temperature change of the hot water is avoided through the return pipe 16 and the branch pipes 30 until the heat of the heat-conducting medium can completely heat the cold water to the required water temperature. Then the return pipe 16 is completely closed, and the power of the second water pump 15 is gradually increased to increase the heat output and improve the heat utilization rate.

[0029] This solar photovoltaic flat plate collector provides electrical energy for all electrical devices through an external power supply. When in use, the water pump 4 pumps the heat-conducting medium in the heat exchange cylinder 2 into the main pipe 3. The heat-conducting medium flows in the main pipe 3, and a part of the heat-conducting medium enters the auxiliary pipe 5 and then returns to the main pipe 3 again. By absorbing the heat converted from solar energy in the flat plate collector 1 through the main pipe 3 and the auxiliary pipe 5, it can effectively utilize the auxiliary pipe 5 to improve the heat absorption efficiency. At the same time, the heat-conducting media in the main pipe 3 and the auxiliary pipe 5 are continuously mixed to ensure uniform heat absorption. The heat-conducting medium enters the connecting sleeve 8, causing the air in the sliding sleeve 10 to expand. The expanded air pushes the sliding rod 9, enabling the sliding sleeve 10 to drive the clamping plate 12 to move left and right through the temperature of the heat-conducting medium. As a result, the clamping plate 12 squeezes the button 11 to the left or right. The button 11 controls the electric valve 7 to adjust the opening degree of the connecting pipe 6. When the power of the heat converted in the flat plate collector 1 is relatively large, the flow rate of the heat-conducting medium becomes faster. When the power of the heat converted in the flat plate collector 1 is relatively small, the flow rate of the heat-conducting medium becomes slower. The heat exchange work is carried out using heat-conducting media with different flow rates, replacing the heat exchange work of heat-conducting media at different temperatures. Thus, the stability of the temperature of the heat-conducting medium is effectively ensured, facilitating the control of the hot water temperature, so as to provide sufficient heat exchange temperature even when the solar energy is weak. Cold water enters the heat exchange cylinder 2 through the conduit 14. The heat-conducting medium flows back and forth downward under the diversion of the partition plate 13 in the heat exchange cylinder 2. The cold water flows spirally upward in the conduit 14 and is pumped out by the water pump 15. If the temperature of the outflowing water is insufficient, the expansion rate of the air in the air sleeve 23 is relatively low. As a result, the piston 24 squeezes the button 27 downward through the push plate 25. The button 27 turns on the motor 22. The motor 22 drives the gate plate 19 to rotate upward inside the gate sleeve 18 through the meshing of the gear 21 and the tooth pattern 20, closing or even shutting off the outlet pipe 17, and opening or even fully opening the return pipe 16, so that the water flows back to the inside of the conduit 14 again through the return pipe 16 and the branch pipe 30 and is heated again by the heat-conducting medium in the heat exchange cylinder 2. At the same time, the power of the water pump 15 is reduced by the frequency converter 29 to lower the water flow rate to ensure that the water can be fully heated. The heated water causes the air in the air sleeve 23 to expand, pushing the piston 24 upward. As a result, the push plate 25 squeezes the button 27 upward, causing the gate plate 19 to rotate downward and increasing the power of the water pump 15 to send out hot water at an appropriate temperature. The temperature change of the hot water is avoided through the return pipe 16 and the branch pipe 30 until the heat of the heat-conducting medium can completely heat the cold water to the required water temperature. Then the return pipe 16 is completely closed, and the power of the water pump 15 is gradually increased to increase the heat output and improve the heat utilization rate. According to the usage requirements, the screw rod 28 is rotated. The screw rod 28 moves up and down through the thread at the top of the air sleeve 23 and drives the movable block 26 to move up and down inside the air sleeve 23 through the bearing, effectively adjusting the height of the button 27 so that the piston 24 can squeeze the button 27 through the push plate 25 at the corresponding temperature.Furthermore, the water temperature flowing out of the pipe 17 can be adjusted as needed, and calibration work can be carried out according to the thermometer on the outlet pipe 17. Furthermore, the output water temperature can be adjusted according to the usage requirements, improving the adaptability of the equipment.
