Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic energy saving, in particular to a photovoltaic energy saving elevator. Background Art

[0002] Photovoltaic elevator is a new type of equipment that combines photovoltaic technology and elevator functions. By installing cadmium telluride power generation glass on the elevator's facade and the top of the shaft, the photovoltaic effect is used to generate clean electricity to power the elevator. The excess electricity can be supplied to other equipment inside the building, achieving efficient use of energy. In photovoltaic elevators, the efficiency of photovoltaic panels is an important factor affecting the operation of photovoltaic elevators, such as: The efficiency of photovoltaic panels decreases as the temperature increases. The ideal operating temperature of photovoltaic panels is usually around 25°C. Solar panels convert absorbed sunlight into usable electricity at this temperature. The ideal operating temperature can improve the conversion efficiency of photovoltaic panels while reducing the damage to the battery caused by heat. However, in actual operation, photovoltaic panels are often affected by high temperatures, resulting in reduced efficiency and energy loss. Photovoltaic panels are installed on the outer facade of the elevator shaft, close to the ground, which causes the dust on the ground to be easily blown to the surface of the photovoltaic panels by the wind. Too much dust will block part of the light, reduce the photovoltaic panels' absorption of solar energy, and reduce the power generation efficiency. Summary of the invention

[0020] Embodiment 1:

[0022] Specific working process: when the ambient temperature is suitable for the photovoltaic panel 11 to work, the electromagnet 18 is powered off, the drive shaft 16 can rotate on the inner wall of the maintenance platform 14, and the drive rope 17 is reeled in or unreeled, so that the maintenance platform 14 is stationary; one end of the linkage rope 25 is disconnected from the car 13, so that the linkage rope 25 is stationary, the sealing block 24 is not pulled by the linkage rope 25 and remains stationary, and there is no air flow in the ventilation pipe 26. The photovoltaic panel 11 works in a suitable ambient temperature, provides electricity to the elevator, and completes the daily work of the photovoltaic energy-saving elevator; When the ambient temperature is high, most of the heat of the photovoltaic panel 11 is concentrated on the backlight side when it is working. Although the light-facing side is directly exposed to the sun, the heat will be quickly transferred to the backlight side, and heat will gather on the back of the photovoltaic panel 11. The efficiency of the photovoltaic panel 11 will decrease with the increase of temperature. The power temperature coefficient of most photovoltaic panels 11 is -0.3% to -0.5% / ℃, that is, for every 1℃ increase in temperature, the power generation efficiency decreases by 0.3% to 0.5%. Under extremely high temperatures, the efficiency loss may be as high as 10%-20%. The power conversion efficiency of the photovoltaic panel 11 is affected; in this environment, the electromagnet 18 remains in a power-off state, and one end of the linkage rope 25 is reconnected to the car 13; when the car 13 descends, the sealing block 24 is driven to rise in the cooling pipe 21 by pulling the linkage rope 25, and the space between the bottom of the cooling pipe 21 and the sealing block 24 increases to form a negative pressure, and the cooling pipe 21 inhales air from the bottom into the cooling box 22, and the cooling box 22 inhales air through the air inlet pipe 23, and the air enters the coolant from the bottom of the air inlet pipe 23. The supercooled liquid bubbles out after washing and cooling. On the one hand, the coolant removes impurities in the air by washing with water to prevent impurities from entering the photovoltaic panel 11. On the other hand, it cools the air by contacting the air to improve the efficiency of air cooling, so that the coolant can cool the air in time, reduce the temperature of the air contacting the photovoltaic panel 11, thereby improving the cooling effect on the photovoltaic panel 11, and further improving the photoelectric conversion efficiency of the photovoltaic elevator; after the air is sucked into the cooling pipe 21, when the car 13 rises, the spring between the sealing block 24 and the cooling pipe 21 drives the sealing block 24 to reset, and the sealing block 24 descends to squeeze the air in the cooling pipe 21, and the one-way valve at the bottom of the cooling pipe 21 forces the air to flow into the ventilation pipe 26, and the ventilation pipe 26 inflates the photovoltaic panel 11, and the air in the photovoltaic panel 11 is ejected through the one-way valve on the other side thereof, so as to achieve the effect of replacing the air inside the photovoltaic panel 11, reduce the internal ambient temperature of the photovoltaic panel 11, improve the heat dissipation effect, and thus improve the photoelectric conversion efficiency of the photovoltaic elevator; When the ambient temperature is too high, such as during the high temperature period in the afternoon in summer, the cooling box 22 is installed in the basement. Due to the thermal insulation effect of the soil, the ambient temperature in the basement is lower than the surface temperature, which helps the cooling box 22 to cool the air. When the basement air is sucked, due to the relatively low thermal conductivity of the soil, the heat needs to pass through a longer path and time to be transferred to the basement, and there will be certain losses in the transfer process; therefore, the basement receives less heat from above the ground, and the air temperature is relatively low, so that the initial air temperature is low, which speeds up the cooling efficiency of the air, thereby improving the cooling efficiency of the photovoltaic panel 11; when the car 13 rises to the top floor, the electromagnet 18 is energized, and one end of the linkage rope 25 is connected to the car 13; the drive shaft 16 is fixedly connected to the maintenance platform 14 through the electromagnet 18, so that when the car 13 descends, the maintenance platform 14 is driven to rise along the photovoltaic panel 11 by pulling the drive rope 17, and the maintenance platform 14 drives the cleaning roller 15 to rise while contacting the photovoltaic panel 11, wiping the light-facing surface of the photovoltaic panel 11 to remove dust and improve the photovoltaic panel 11 is clean, and shielding is reduced, thereby improving the photoelectric conversion efficiency of the photovoltaic elevator; and, the maintenance platform 14 drives the water tank 19 to rise, and the water tank 19 transports a special cleaning solution or water to the cleaning roller 15 through a water pipe, and the water is sprayed from the spray hole 2 to the light-facing surface of the photovoltaic panel 11, and the light-facing surface of the photovoltaic panel 11 is rinsed to reduce the temperature of the light-facing surface, and avoid the high temperature chamber. The temperature difference between the light-facing surface and the backlight surface of the photovoltaic panel 11 is too large, resulting in damage to the photovoltaic panel 11, thereby increasing the protection measures for the photovoltaic panel 11 and improving the use effect; and, the rinsing equipment Combined with the above-mentioned air cooling effect on the backlight surface, the cooling effect is improved by cooling the two surfaces of the photovoltaic panel 11, thereby improving the photoelectric conversion efficiency of the photovoltaic elevator; in addition, the water tank 19 is located outside the maintenance platform 14 and is first exposed to the sun, so that the temperature in the water tank 19 is preheated in advance to avoid the glass on the light-facing side of the photovoltaic panel 11 being washed by cold water during washing, resulting in cracks. The temperature of the water raised by the sun is much lower than the temperature generated by the photoelectric conversion of the photovoltaic panel 11, so that during the high-temperature washing process, the water will not cause the photovoltaic panel 11 to heat up; Furthermore, by lifting and lowering the maintenance platform 14, the cleaning roller 15 is driven to lift and lower to wipe the photovoltaic panel 11; in summer, the water stains formed by rainwater after rain are wiped off the photovoltaic panel 11; in winter, the snow is wiped off the photovoltaic panel 11, thereby improving the cleanliness of the photovoltaic panel 11, and then improving the photoelectric conversion efficiency of the photovoltaic elevator, and avoiding the photovoltaic panel 11 from being blocked by snow, water stains or dust; and in winter, the light-facing surface of the photovoltaic panel 11 may be frozen. After the water tank 19 is heated by the sun, the light-facing surface of the photovoltaic panel 11 is rinsed through the spray hole 2 to remove the ice, thereby improving the convenience of use; and if the photovoltaic panel 11 needs to be replaced and repaired, the workers can lift and lower along the photovoltaic panel 11 through the maintenance platform 14.

Scratches or damaged areas may cause local temperature anomalies, and these hot spots can be detected using an infrared thermal imager; the motor 35 is a conventional electric device.

[0025] Specific working process: when the maintenance platform 14 rises, a sliding friction resistance is generated between the swing rod 33 and the main frame 1, and the swing rod 33 is affected by the friction resistance and is toggled to rotate, that is, the swing rod 33 changes from an oblique upward state to an oblique downward state; the swing rod 33 drives the swing blade 3 to rotate, and the swing blade 3 squeezes the upper support rod 31 to push the cleaning roller 15 to move horizontally to contact the photovoltaic panel 11. At this time, the swing blade 3 is away from the lower support rod 31, and the lower support rod 31 drives the wiper plate 32 away from the photovoltaic panel 11, so that when the maintenance platform 14 rises, the cleaning roller 15 can spray and scrub the photovoltaic panel 11 with water, ensuring that the light-facing surface of the photovoltaic panel 11 can be completely washed, thereby improving the washing effect and thus improving the cooling effect; When the maintenance platform 14 descends, the swing rod 33 changes from a downwardly inclined state to an upwardly inclined state, and the swing blade 3 squeezes the lower support rod 31 to push the wiper 32 to move horizontally to contact the photovoltaic panel 11. At this time, the swing blade 3 is away from the upper support rod 31, and the upper support rod 31 drives the cleaning roller 15 away from the photovoltaic panel 11, and the water tank 19 no longer supplies water, so that when the maintenance platform 14 descends, the wiper 32 scrapes the photovoltaic panel 11, scraping off the water on the light-facing surface of the photovoltaic panel 11 to avoid excessive water stains that affect the photoelectric conversion. Scratches on the light-facing surface of the photovoltaic panel 11 will block part of the light, reduce the absorption of solar energy by the photovoltaic panel 11, and thus reduce the power generation efficiency. In addition, scratches may damage the anti-reflective coating on the surface of the photovoltaic panel 11, causing local temperature rise and triggering the hot spot effect, which may damage the battery cells in the long term. When the maintenance platform 14 descends, the wiper 32 scrapes off the water on the photovoltaic panel 11, and the detector 34 detects the light-facing surface of the photovoltaic panel 11, and marks and replaces the photovoltaic panel 11 with more scratches. Moreover, after rinsing, the temperature of the light-facing surface of the photovoltaic panel 11 decreases, while the scratched part triggers the hot spot effect, and the scratched part heats up faster than the intact part. This method can help the detection of the detector 34, improve the detection accuracy, and repair the photovoltaic panel 11 with more scratches in time. In a photovoltaic elevator, the photovoltaic panel 11 close to the ground is prone to oil stains or smearing by humans, which are difficult to remove by rinsing; therefore, during rinsing, the cleaning roller 15 moves laterally close to the photovoltaic panel 11, while the bottom of the cleaning roller 15 contacts the cleaning soap 37, and the motor 35 drives the cleaning roller 15 to rotate. When the cleaning roller 15 rotates, it rubs against the cleaning soap 37, and the cleaning ingredients in the cleaning soap 37 are smeared on the surface of the cleaning roller 15. As the cleaning roller 15 rotates, the cleaning roller 15 mixed with water and cleaning ingredients wipes the photovoltaic panel 11, wipes off the oil stains on the surface, improves the cleanliness of the photovoltaic panel 11, and thus improves the photoelectric conversion efficiency of the photovoltaic elevator; because the cleaning soap 37 achieves the lifting effect through the tray 36, during the cleaning When the soap 37 is reduced after use, the tray 36 drives the cleaning soap 37 to rise and contact the cleaning roller 15 through the spring, and maintains the friction force between the cleaning roller 15 and the cleaning soap 37, which helps the cleaning ingredients to adhere to the surface of the cleaning roller 15, thereby improving the cleaning effect; while the cleaning roller 15 is away from the photovoltaic panel 11, it is also away from the tray 36 and the cleaning soap 37; and during the rinsing process, since the wiper blade 32 is located below the tray 36 and the wiper blade 32 is tilted close to the photovoltaic panel 11, the water generated by the rinsing will drip onto the wiper blade 32, and the soap water can contact the photovoltaic panel 11 under the guidance of the wiper blade 32, thereby improving the rinsing effect, and cooperating with the air cooling effect of the backlight surface of the photovoltaic panel 11, further improving the heat dissipation effect; The cleaning roller 15 rotates to drive the guide block 41 to rotate. During the rotation of the guide block 41, it contacts the inclined surface of the pressing block 57. The guide block 41 drives the tray 36 to move and extend into the slider 38 on one side through the pressing block 57. When the guide block 41 passes over the pressing block 57, the tray 36 drives the cleaning soap 37 to extend from the slider 38 on one side, so that the tray 36 drives the cleaning soap 37 to move back and forth, so that the tray 36 drives the cleaning soap 37 to rub the surface of the cleaning roller 15, promotes the generation of cleaning foam on the surface of the cleaning roller 15, is beneficial to the cleaning of the photovoltaic panel 11 by the cleaning roller 15, improves the cleaning effect, and thus improves the cleanliness of the photovoltaic panel 11; and when the cleaning roller 15 is away from the cleaning soap 37, the slider 38 drives the cleaning soap 37 to rise to the limit position through the tray 36 and then stands still; By setting the hook 42, the cleaning roller 15 rotates to contact the hook 42. On the one hand, the hook 42 combs the bristles on the surface of the cleaning roller 15, scrapes off the dust mixed in the bristles, and improves the cleanliness of the bristles. On the other hand, the tray 36 drives the hook 42 to move back and forth, so that the hook 42 can reciprocate the bristles on the surface of the cleaning roller 15, improve the rubbing effect, accelerate the generation of cleaning foam, and improve the cleaning effect; The cleaning roller 15 then moves away from the cleaning soap 37 and the cleaning roller 15 moves away from the cleaning soap 37 to move the cleaning soap 37 to the cleaning roller 15. The cleaning roller 15 then moves away from the cleaning soap 37 and the cleaning soap 37 to the cleaning roller 15 to move the cleaning soap 37 to the cleaning roller 15. The cleaning roller 15 then moves away from the cleaning soap 37 and the cleaning soap 37 to the cleaning roller 15 to move the cleaning soap 37 to the cleaning roller 15. The cleaning roller 15 then moves away from the cleaning soap 37 and the cleaning soap 37 to the cleaning roller 15 to move the cleaning soap 37 to the cleaning roller 15. The cleaning ingredients affect the cleanliness of the photovoltaic panel 11; at this time, the lever 45 is limited and no longer swings, and the lever 45 rolls along the surface of the lever block 47 through the ball 46 at the end until the lever 45 and the slide bar 44 pass over the lever block 47 by lifting, so that the tray 36 located below drives the cleaning soap 37 away from the cleaning roller 15, and the tray 36 located above continues to contact the cleaning roller 15 through the hook 42, rubbing and removing the cleanliness in the cleaning roller 15 while scraping off the dust mixed in the cleaning roller 15, that is: when the cleaning roller 15 rotates forward, the upper and lower trays 36 are close to the cleaning roller 15; when the cleaning roller 15 reverses, the upper tray 36 is close to the cleaning roller 15, and the lower cleaning roller 15 is away from the cleaning roller 15; when the cleaning roller 15 reverses to forward rotation, the lever block 47 rotates forward to contact the lever 45, and the lever block 47 squeezes the lever 45 to make it swing and contact the guide ring 43 in an inclined state, thereby completing the reset of the lever 45.

[0026] Embodiment three:

[0027] On the basis of the second embodiment, the outer ring surface of the sealing block 24 is evenly provided with sealing strips 5, and the sealing strips 5 are distributed at the top and bottom of the sealing block 24 and contact the inner wall of the cooling tube 21; the sealing block 24 stores lubricating fluid, and the outer ring surface of the sealing block 24 is evenly provided with lubricating holes 51, the lubricating holes 51 are obliquely upward toward the inner wall of the cooling tube 21, and the lubricating holes 51 are located between adjacent sealing strips 5; the top of the sealing block 24 is provided with a sealing rod 52, the bottom of the sealing rod 52 contacts and squeezes the lubricating fluid, and the top of the sealing rod 52 is located above the sealing block 24; the top of the cooling tube 21 is provided with an electric push rod 53, and a sensor is provided in the photovoltaic panel 11, and the sensor controls the electric push rod 53; A storage box 54 is provided in the cooling tube 21, and the two ends of the storage box 54 are located on both sides of the outside of the cooling tube 21. The part of the storage box 54 located in the cooling tube 21 is tilted, and the storage box 54 located inside the cooling tube 21 is in the shape of a filter screen; a water-absorbing cloth 55 is rolled up in the storage box 54, and water-absorbing material is added in the water-absorbing cloth 55. The two ends of the water-absorbing cloth 55 are respectively rolled up with the two ends of the storage box 54, and the water-absorbing cloth 55 is rolled up from high to low; The sensor is a conventional sensor for detecting temperature and humidity; the lubricating liquid is a conventional electronic fluoride liquid; the storage box 54 is a conventional device with a winding function, and winding wheels are provided at both ends of the storage box; the absorbent material in the absorbent cloth 55 can be selected from saltpeter components, and the principle of saltpeter absorbing heat when it meets water is used to reduce the air temperature.

[0028] Specific working process: the sealing block 24 drives the sealing strip 5 to rise and fall in the cooling tube 21. When the temperature in the photovoltaic panel 11 is too high, the electric push rod 53 is started, and the bottom of the electric push rod 53 extends toward the bottom of the cooling tube 21; when the car 13 descends to the bottom layer, the sealing block 24 rises to the top of the sealing rod 52 to contact the bottom of the electric push rod 53, and the electric push rod 53 squeezes the sealing rod 52 to descend in the sealing block 24, and squeezes the lubricating fluid in the sealing block 24 into the lubricating hole 51, and squeezes the lubricating fluid into the space between adjacent sealing strips 5 through the lubricating hole 51, so as to fully lubricate the inner wall of the cooling tube 21, reduce the heat generated by friction, and avoid the cooling tube 21 from being subjected to frictional heat, which affects the temperature of the air blown to the inside of the photovoltaic panel 11, thereby maintaining the low temperature effect of the air, and further improving the heat dissipation effect of the photovoltaic panel 11; Furthermore, since the lubricating liquid can be selected from electronic fluorinated liquid, which has a low evaporation point, and when it is replaced and discharged from the inside of the photovoltaic panel 11, workers can add an adsorbent, such as activated carbon, at one end of the photovoltaic panel 11, and adsorb the remaining electronic fluorinated liquid through a conventional adsorption method. When the inner wall of the cooling tube 21 generates heat due to friction, the electronic fluorinated liquid evaporates and absorbs heat, which reduces the temperature of the cooling tube 21 and helps to cool the air. On the other hand, the evaporated fluorinated liquid gas enters the photovoltaic panel 11 with the air as a coolant, effectively controlling the temperature, ensuring stable operation, and improving the photoelectric conversion efficiency of the photovoltaic elevator. It can also be used as a cleaning agent to effectively remove impurities and pollutants on the surface of the semiconductor in the photovoltaic panel 11, thereby improving performance and reliability. By setting up the storage box 54, when the cooling pipe 21 inhales air, the air passes through the absorbent cloth 55. Since the air has been washed with water, the humidity in the air is relatively high. Therefore, when the air carries moisture and passes through the absorbent cloth 55, on the one hand, the absorbent cloth 55 absorbs moisture in the air through the saltpeter component, and on the other hand, the temperature of the absorbent cloth 55 is reduced. When the air passes through the absorbent cloth 55, it is cooled, thereby improving the cooling effect on the photovoltaic panel 11.

[0029] Embodiment 4:

[0030] On the basis of the third embodiment, the top of the storage box 54 located in the cooling pipe 21 is provided with a water-absorbing sponge 56, and the water-absorbing cloth 55 is located in the water-absorbing sponge 56; the bottom of the sealing block 24 is slidably connected with a pressing block 57 through a spring, and the bottom of the pressing block 57 passes through the water-absorbing sponge 56 and contacts the water-absorbing cloth 55; A filter screen 58 is provided in the cooling box 22 . The filter screen 58 is located below the cooling pipe 21 , and the coolant submerges the filter screen 58 . The bottom of the air intake pipe 23 is located below the filter screen 58 .

[0031] Specific working process: Due to the provision of the water-absorbing sponge 56, when the air passes through the water-absorbing sponge 56, the water-absorbing sponge 56 absorbs the moisture in the air and gathers it inside, and the water-absorbing cloth 55 inside the water-absorbing sponge 56 contacts and absorbs the gathered moisture, thereby improving the water absorption effect of the water-absorbing cloth 55 and reducing the air humidity; and, the sealing block 24 descends to drive the pressing block 57 to descend, and the pressing block 57 passes through the water-absorbing sponge 56 to contact the water-absorbing cloth 55. After being squeezed, the pressing block 57 slides along the inclined part of the storage box 54, and the friction resistance generated by the contact at the bottom of the pressing block 57 drives the water-absorbing cloth 55 to move obliquely downward to the storage box 54. One end of the box 54 is rolled up, while the other end of the storage box 54 unwinds a new absorbent cloth 55 for drying the air, completing the replacement of the old absorbent cloth 55 with the new one, thereby improving the convenience of use; moreover, since the old absorbent cloth 55 is located at the obliquely lower end of the storage box 54, if there are water droplets attached to the absorbent cloth 55, the water droplets will flow to the obliquely lower end due to the influence of gravity and contact the old absorbent cloth 55 again, making full use of the saltpeter component in the absorbent cloth 55, thereby reducing the temperature of the storage box 54 and further reducing the air temperature; when the sealing block 24 rises, the pressing block 57 is affected by the spring and slides back to reset; When the air intake pipe 23 transports air into the coolant, if the air bubbles formed in the coolant are too large, the water washing and dust removal effect of the air will be affected; therefore, by setting the filter 58, when the air bubbles pass through the filter 58, the filter 58 can play a role in separating the bubbles, dividing the air bubbles into multiple small bubbles, thereby improving the contact effect between the air and the coolant, thereby improving the water washing effect of the air, and then improving the cleanliness of the air.
