Description

Technical Field

[0001] The present invention relates to the field of photoelectric conversion technology, and in particular to a photoelectric conversion method and a conversion device thereof. Background Art

[0002] As a leader in the field of renewable energy, solar energy continues to attract global attention with its efficient conversion technology into electrical energy. Among the many solar power generation methods, photovoltaic power generation has become a popular mainstream method with its excellent conversion efficiency, outstanding safety and high adaptability. The essence of this technology lies in the photovoltaic effect occurring at the semiconductor interface - when the semiconductor material is excited by light, it can generate an electromotive force and directly convert light energy into electrical energy. The core component of this conversion process is the solar cell.

[0003] The power generation efficiency of solar cells is closely related to the lighting conditions. In the initial stage when the light gradually increases, the voltage of the panel will rise rapidly until it reaches a stable operating voltage, and then the voltage will remain basically unchanged. However, it is worth noting that as the sunlight increases, the temperature of the solar panel will also rise. This temperature increase will cause the voltage to drop, the resistance in the power generation circuit to increase, and then reduce the current, so that the power of photovoltaic power generation will decrease. In short, as the temperature increases, the power of photovoltaic power generation will tend to decrease.

[0004] In response to the above problems, a Chinese patent with application number CN202210607734.0 discloses a photovoltaic module and a backplane structure of a photovoltaic module. The photovoltaic module includes: a plurality of battery cells, a heat-conducting plate, a heat-conducting fin, a cover plate and a backplane; wherein the heat-conducting plate is in a grid shape, and the heat-conducting plate is arranged between the cover plate and the backplane; the plurality of battery cells are respectively embedded in a plurality of grids of the heat-conducting plate; the heat-conducting plate is connected to the heat-conducting fin, and the heat-conducting fin is arranged on the backplane; the heat-conducting plate and the heat-conducting fin are made of heat-conducting material. The photovoltaic module and the backplane structure improve the photoelectric conversion efficiency of the battery cell and also slow down the aging rate of the battery cell.

[0005] In summary, although the existing patented design has improved the heat dissipation performance of photovoltaic panels to a certain extent by introducing heat-conducting plates and heat-conducting fins, in actual applications, the heat conduction effect of the heat-conducting fins and heat-conducting plates alone is not enough to achieve sufficient cooling of the photovoltaic panels. It is particularly noteworthy that the heat-conducting fins and heat-conducting plates are located on the back of the photovoltaic panel, while the front temperature is mainly affected by the intensity of solar radiation and the working state of the photovoltaic cells. Although the heat-conducting fins installed on the back can take away some heat, they are limited by the efficiency of the heat conduction path and their effect on reducing the front temperature is relatively limited.

[0006] In addition, in the normal operation of photovoltaic panels, photovoltaic panels are often fixed at a certain angle and cannot be adjusted with the change of the sun's position. This results in the photovoltaic panels being able to effectively absorb more energy when the sunlight is vertical, and the absorption efficiency is greatly reduced when the sunlight is tilted. Although there are solar tracking devices on the market, most of them use photoresistors on the surface of solar panels to sense the angle of sunlight, but such devices are susceptible to interference from the external environment. Once the photoresistor is blocked, the tracking device cannot accurately identify the angle of sunlight, which in turn affects the power generation efficiency of the photovoltaic panel.

[0007] Therefore, in view of the limitations of current solar cell technology, developing an efficient photoelectric conversion method and corresponding conversion device is particularly urgent and important to promote the development of related technical fields. Summary of the invention

[0013] Preferably, the conduction component comprises a conduction tube, one end of which is connected to the fixing tube, and the other end of which is connected to the area between the second elastic member and the first elastic member; A conducting hole, wherein the conducting hole is arranged on the outer wall of the fixing tube, and the conducting hole connects the second elastic member with the fixing tube; The diverter hole is arranged on the outer wall of the fixed tube and is connected to the diverter tube.

[0014] Preferably, the conduction assembly further comprises a movable block, which is arranged inside the fixed tube and is sealingly and slidingly connected with the fixed tube, and a conduction groove is arranged on the movable block; The telescopic tube has one end connected to the movable block and the other end connected to the fixed block.

[0015] Preferably, the photosensitive detection component includes a photoresistor, a mounting groove is provided on the top of the base, and a photoresistor is provided inside the mounting groove; An expansion piece is provided inside the installation groove, the expansion piece is located outside the photoresistor, and a light-transmitting plate is provided on the top of the expansion piece.

[0016] Preferably, the light chasing device comprises a first transmission member and a second transmission member, the first transmission member is provided on the top of the base, symmetrically distributed supports are provided on the top of the first transmission member, and the second transmission member is provided between two adjacent supports; The driving source is arranged on the top of the base and is used to drive the first transmission member and the second transmission member to operate.

[0017] Preferably, the first transmission member comprises a first driving wheel arranged on the top of the base, a first driven wheel is meshed on the outer side of the first driving wheel, and the support is arranged on the top of the first driven wheel; The first driven wheel comprises a second driving wheel arranged between two supports, a second driven wheel is meshed on the outer side of the second driving wheel, and the second driven wheel is connected to the mounting seat.

[0018] A conversion method for a photoelectric conversion device, the conversion method comprising the following steps: S1. By comparing and analyzing the light intensity data sensed by photoresistors distributed at different positions, the incident direction of the sunlight is determined. Based on this determination result, the mechanical adjustment function of the light-chasing device is used to dynamically adjust the tilt angle of the photovoltaic panel to ensure that it is continuously aligned with the sunlight source to maximize the light energy capture efficiency. S2. During the operation of the photovoltaic panel, the resistance fluctuation of the photoresistor installed on the base is continuously monitored to serve as a basis for evaluating whether the light-transmitting panel is blocked by external objects; S3. When it is confirmed that the obstruction is dust, the conduction component is activated to inject a specific medium into the elastic member in the preset area, causing the elastic member to expand and build a physical barrier. Subsequently, the medium is guided to be discharged in an orderly manner through the connecting hole by utilizing the regulating function of the diversion component to form a flushing flow, effectively removing dust accumulation on the surface of the photovoltaic module and the light-transmitting plate; S4. When it is confirmed that the obstruction is snow, the movable block is driven to reciprocate in the fixed tube to generate high-frequency vibration to loosen the snow physically. At the same time, the diversion component is activated to pump the medium into the diversion block under pressure. The medium is then sprayed directly onto the surface of the photovoltaic module through the connecting hole. The flushing force of the medium is used to directly remove the snow, ensuring that the normal operation of the photovoltaic system is not affected.

[0019] Technical effects and advantages of the present invention: 1. The present invention sets expansion parts and conduction components. When the resistance of the photoresistor drops below the preset threshold and the readings of the temperature sensor and the pressure sensor remain stable, the control system recognizes that dust is blocking the light-transmitting plate. Subsequently, by regulating the movement of the movable block and the injection of the medium, a unique "inverted triangle" shaped barrier is constructed on both sides of the photovoltaic module. This barrier not only effectively guides the medium to be discharged from the connecting hole, forming a powerful flushing flow to directly flush away the dust on the surface of the light-transmitting plate, but also significantly improves the cleaning efficiency and avoids the tediousness and high cost of manual cleaning.

[0020] 2. The present invention sets expansion pieces and conduction components, and for heavy obstructions such as snow and ice, the reciprocating movement of the movable block in the fixed tube effectively drives the mounting plate to generate high-frequency vibrations; this vibration can deeply loosen the snow and ice, laying a solid foundation for subsequent removal work; at the same time, the medium pumping system is started to directly flush the photovoltaic module through the connecting hole. In particular, when the diverter block is set to be rotatable, the medium can act more accurately on the connection between the ice layer and the photovoltaic panel, accelerating the melting and loosening of the ice layer, thereby significantly improving the effect of clearing snow and ice.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0025] Reference Figures 1 to 10 As shown, the present invention provides a photoelectric conversion device, including a base 1 and a photovoltaic panel 4.

[0026] It also includes a light-chasing device 2 , which is arranged on the base 1 and connected to the photovoltaic panel 4 through a mounting seat 3 .

[0027] The photosensitive detection components 5 are arranged at the four corners of the photovoltaic panel 4 and are used to detect the light intensity of the surrounding environment.

[0028] Reference Figure 3 As shown, the photovoltaic panel 4 includes a base 401 which is arranged on the top of the mounting seat 3 , and a connecting frame 402 is arranged on the outer side of the base 401 , and the base 401 is connected to the mounting seat 3 through the connecting frame 402 .

[0029] The photovoltaic modules 403 , whose array is distributed on the surface of the base 401 , are used to convert light energy into electrical energy.

[0030] Reference Figure 1 to Figure 2 As shown, the light chasing device 2 includes a first transmission member 201 and a second transmission member 203 . The first transmission member 201 is disposed on the top of the base 1 . Symmetrically distributed supports 202 are disposed on the top of the first transmission member 201 . A second transmission member 203 is disposed between two adjacent supports 202 .

[0031] The driving source 204 is disposed on the top of the base 1 and is used to drive the first transmission member 201 and the second transmission member 203 to operate.

[0032] Reference Figure 1 to Figure 2 As shown, the first transmission member 201 includes a first driving wheel 2011 disposed on the top of the base 1 , a first driven wheel 2012 is meshed on the outer side of the first driving wheel 2011 , and the support 202 is disposed on the top of the first driven wheel 2012 .

[0033] The first driven wheel 2012 includes a second driving wheel 2031 disposed between the two supports 202 . The second driven wheel 2032 is meshed with the outer side of the second driving wheel 2031 . The second driven wheel 2032 is connected to the mounting seat 3 .

[0034] The photoresistor 502 is a special resistor whose resistance value can change with the change of light intensity. When light shines on the photoresistor 502, the semiconductor material inside it absorbs the photon energy, causing the resistivity to change, and then changing the resistance value. This change is the basis for the photoresistor 502 to detect the light intensity.

[0035] When in use, the photoresistor 502 is used to detect the direction and intensity of sunlight. The control system can determine the direction of sunlight by comparing the light intensity sensed by the photoresistors 502 at different positions of the photovoltaic panel 4. The specific operation is as follows: after the light intensity signal sensed by the photoresistor 502, the light signal enters the operational amplifier after passing through the photoresistor 502 module, and the operational amplifier amplifies the signal and further processes it. Then, the processed signal is compared with the reference voltage through a comparator to obtain an error signal. This error signal reflects the deviation between the current direction of the photovoltaic panel 4 and the direction of sunlight.

[0036] According to the error signal, the control system drives the first transmission member 201 and the second transmission member 203 of the stepper motor to operate accordingly, so as to adjust the angle of the photovoltaic panel 4 so that the photovoltaic panel 4 can always face the sunlight source.

[0037] It should be noted that: the first driving wheel 2011 and the first driven wheel 2012 in the first transmission member 201 are used to control the support 202 to rotate in the Z-axis direction, so as to adjust the axial angle of the photovoltaic panel 4; the second driving wheel 2031 and the second driven wheel 2032 in the second transmission member 203 are used to drive the mounting seat 3 to deflect on the support 202 to meet the deflection angle of the photovoltaic panel 4 at different times. In order to ensure that the photovoltaic panel 4 is always facing the sun, the photovoltaic tracking system usually adopts a feedback control mechanism. The control system continuously monitors the direction of the photovoltaic panel 4 and makes fine adjustments as needed to maintain the optimal light absorption rate. Example 2

[0038] Although implementation one can improve the efficiency of photoelectric conversion by setting up a photovoltaic tracking system, in actual applications, as the sunlight increases, the temperature of the solar panel will also rise. This temperature increase will cause the voltage to drop, the resistance in the power generation circuit to increase, and then reduce the current, so that the power of photovoltaic power generation will decrease. In short, as the temperature increases, the power of photovoltaic power generation will tend to decrease. In view of this, technical improvements are made on the basis of implementation one, and the improved technical solution is as follows: Reference Figures 1 to 10As shown, a photoelectric conversion device proposed in the present invention also includes a partition component 6, which includes a partition groove array distributed on the surface of the photovoltaic panel 4, a fixed block 601 is provided in the middle of the partition groove, and fixed tubes 602 are provided at both ends of the fixed block 601, and an elastic member is provided on the outer side of the fixed tube 602.

[0039] The conducting component 7 is arranged inside the fixing tube 602 and is used to adjust the expansion amount of the elastic member.

[0040] Reference Figures 4 to 9 As shown, the elastic member includes a first elastic member 603 arranged outside the fixing tube 602 , and a second elastic member 604 is arranged between the first elastic member 603 and the fixing tube 602 .

[0041] The cross-sectional areas of the front and rear ends of the first elastic member 603 are consistent; the cross-sectional areas of the front and rear ends of the second elastic member 604 are inconsistent. Specifically, the cross-sectional area of ​​the second elastic member 604 gradually decreases from the fixed block 601 to the end of the fixed tube 602 away from the fixed block 601.

[0042] Reference Figures 6 to 9 As shown, a flow diversion component 8 is provided between two adjacent partition components 6 , and the flow diversion component 8 includes a flow diversion block 801 , which is provided on the top of the base 401 and located between the two adjacent partition components 6 .

[0043] The top of the diversion block 801 is wedge-shaped. After the natural wind flows to the surface of the photovoltaic panel 4, it will contact the diversion block 801, thereby generating diversion. The diverted natural wind blows on the surface of the photovoltaic panel 4, thereby improving the heat dissipation effect of the photovoltaic panel 4.

[0044] Partition 802 : A cavity is provided inside the diverter block 801 , and a partition 802 is provided inside the cavity. The partition 802 divides the cavity into two independent chambers 805 .

[0045] The connecting holes 803 are arranged in an array on both sides of the diverter block 801 . The connecting holes 803 on both sides of the diverter block 801 are respectively connected to the independent chambers 805 on both sides of the partition plate 802 .

[0046] The shunt pipe 804 is disposed at both ends of the independent chamber 805 and is used to introduce the medium into the independent chamber 805 .

[0047] Reference Figures 4 to 5 As shown, the conducting component 7 includes a conducting tube 701 , one end of which is connected to the fixing tube 602 , and the other end of which is connected to the area between the second elastic member 604 and the first elastic member 603 .

[0048] The conducting hole 702 is disposed on the outer wall of the fixing tube 602 , and the conducting hole 702 connects the second elastic member 604 with the fixing tube 602 .

[0049] Reference Figures 4 to 5 As shown, the conducting assembly 7 further includes a movable block 704 , which is disposed inside the fixed tube 602 and is sealingly and slidingly connected to the fixed tube 602 , and a conducting groove 705 is disposed on the movable block 704 .

[0050] The telescopic tube 706 has one end connected to the movable block 704 and the other end connected to the fixed block 601 . A conveying device is provided on the outer side of the fixed block 601 . The conveying device conveys the medium to the conducting groove 705 through the telescopic tube 706 .

[0051] The delivery device includes a water pump disposed inside the base 401 , and the water pump pumps the medium into the telescopic tube 706 through the delivery pipe.

[0052] It should be noted that: an electromagnetic component is provided between the movable block 704 and the fixed block 601, specifically, an electromagnetic block provided on the movable block 704, and a magnetic block provided on the fixed block 601. By controlling the magnitude and direction of the current passing into the electromagnetic block, the movable block 704 can be controlled to move inside the fixed tube 602. The electromagnetic component is provided to drive the movable block 704 to move inside the fixed tube 602, which belongs to the prior art and will not be described in detail here. The power supply of the electromagnetic component is derived from the power supply generated by the photovoltaic panel 4.

[0053] Specifically, a diversion hole 703 is provided on the outer wall of the fixed tube 602 , and the diversion hole 703 is connected to the diversion tube 804 .

[0054] When the movable block 704 is in the first position, the conducting groove 705 is connected to the conducting tube 701 , and the medium entering the telescopic tube 706 enters the area between the first elastic member 603 and the second elastic member 604 through the conducting tube 701 .

[0055] When the movable block 704 is in the second position, the conducting groove 705 is connected to the conducting hole 702 , and the medium entering the telescopic tube 706 enters the area between the second elastic member 604 and the fixed tube 602 through the conducting hole 702 .

[0056] When the movable block 704 is in the third position, the conducting groove 705 is connected with the diverter hole 703 , and the medium entering the telescopic tube 706 enters the diverter pipe 804 through the diverter hole 703 , and enters the inside of the diverter block 801 through the diverter pipe 804 .

[0057] The conducting groove 705 is in a "T" shape, and the conducting pipe 701, the conducting hole 702 and the diverter hole 703 are respectively located at different positions of the fixed pipe 602, and the conducting groove 705 can only be connected with any one of the components at the same position.

[0058] Specifically, the photosensitive detection component 5 includes a photoresistor 502 . A mounting groove 501 is provided on the top of the base 401 , and a photoresistor 502 is provided inside the mounting groove 501 .

[0059] An expansion member 503 is provided inside the mounting groove 501 , and the expansion member 503 is located outside the photoresistor 502 . A light-transmitting plate 504 is provided on the top of the expansion member 503 .

[0060] The expansion member 503 comprises a transparent elastic expansion member, and the expansion member is internally encapsulated with a gas that expands when heated. One end of the expansion member is connected to the mounting groove 501, and a pressure sensor is integrated at this connection to monitor the deformation degree of the expansion member caused by the gas expansion, thereby indirectly reflecting the elongation of the expansion member 503. A temperature sensor is also embedded in the mounting groove 501 to monitor the temperature in the base 401 area. The higher the temperature, the greater the elongation of the expansion member 503, and the lower the temperature, the smaller the elongation of the expansion member 503, and the change in temperature is directly proportional to the elongation of the expansion member 503.

[0061] Under normal conditions, the resistance of the photoresistors 502 located at the four corners of the base 401 remains stable, that is, the resistance of the photoresistors 502 does not drop below the preset threshold. At this time, the control system commands the light-chasing device 2 installed on the base 1 to operate according to the resistance distribution of each photoresistor 502, ensuring that the front of the photovoltaic panel 4 is continuously facing the sun to maximize the power generation efficiency.

[0062] During the operation of the photovoltaic panel 4 , the control system synchronously monitors the reading of the temperature sensor in the installation slot 501 to determine whether heat dissipation measures need to be implemented for the photovoltaic panel 4 .

[0063] Once the value recorded by the temperature sensor exceeds the preset threshold, the control system controls the electromagnetic member between the fixed block 601 and the movable block 704 to cause the movable block 704 to slide in the fixed tube 602 until it reaches the preset first position. At this time, the flow hole on the movable block 704 is aligned with and connected to the conducting tube 701. Subsequently, the control system controls the conveying device to pump the medium (the medium is antifreeze glass water) into the telescopic tube 706. The medium enters the space defined by the first elastic member 603 and the second elastic member 604 through the telescopic tube 706 and the conducting tube 701. As the medium is continuously injected, the first elastic member 603 gradually expands and eventually forms a barrier on both sides of the photovoltaic module 403. After encountering this barrier and the diversion block 801 set in the middle of the base 401, the natural wind is forced to be diverted to the upper and lower sides of the base 401. During the flow process, the wind speed is accelerated by the guidance of the barrier, and the heat on the surface of the photovoltaic panel 4 is more effectively taken away. In addition, since the first elastic member 603 is filled with antifreeze glass water, while the natural wind takes away the heat of the photovoltaic panel, the medium can also further enhance the cooling effect of the photovoltaic panel 4 through heat exchange with the natural wind.

[0064] When the control system detects that the resistance of the photoresistor 502 at a certain point on the base 401 is lower than a preset threshold, it indicates that the light-transmitting plate 504 arranged on the top of the expansion member 503 is blocked, resulting in that light cannot pass through the light-transmitting plate 504 to be received by the photoresistor 502. At this time, the control system further detects the temperature sensor and the pressure sensor arranged inside the installation groove 501 to determine what material is blocking the light-transmitting plate 504, and controls the partition component 6 and the conductive component 7 to make corresponding structural changes.

[0065] If the control system confirms that the temperature sensor and the pressure sensor are both stable and the extension of the expansion member 503 is proportional to the external ambient temperature, this usually means that the obstruction is a light material, such as dust. The dust is deposited on the light-transmitting plate 504, preventing light from penetrating to the photoresistor 502.

[0066] by Fig. 9 and Fig.10 Taking the structure shown as an example, the partition component 6 and the conduction component 7 are divided into two areas S1 and S2. The fixed pipe 602 in the S1 area is connected to the independent chamber 805 in the S2 area through the shunt pipe 804, and the fixed pipe 602 in the S2 area is also connected to the independent chamber 805 in the S1 area through the shunt pipe 804.

[0067] When the control system recognizes that the blocking material is dust, and the blocked light-transmitting plate 504 is located in the S2 area, the movable blocks 704 on both sides of the light-transmitting plate 504 in the S2 area are controlled to move to the second position, so that the conducting groove 705 is aligned with the conducting hole 702, and the conveying device is activated to inject the medium (the medium here is antifreeze glass water) into the telescopic tube 706. The medium flows into the space surrounded by the second elastic member 604 and the fixed tube 602 through the telescopic tube 706 and the conducting hole 702. As the medium is continuously injected, the second elastic member 604 gradually expands, and finally builds a barrier on both sides of the photovoltaic module 403. Since the cross-sectional area of ​​the second elastic member 604 gradually decreases from the fixed block 601 to the end away from the fixed block 601, the area formed by the expanded second elastic member 604 on both sides of the photovoltaic module 403 presents an "inverted triangle" shape (see for details). Fig. 9 The bottom of the “inverted triangle” faces the photosensitive detection component 5.

[0068] At the same time, the movable blocks 704 on both sides of the light-transmitting plate 504 in the S1 region are controlled to move to the third position, so that the conducting groove 705 is connected with the diverter hole 703. At this time, the medium entering the telescopic tube 706 flows into the diverter tube 804 through the diverter hole 703, and then enters the inside of the diverter block 801, and the medium continues to be pumped to the telescopic tube 706 through the conveying device. The medium finally enters the independent chamber 805 in the S2 region through the telescopic tube 706 and the diverter tube 804, and is discharged from the connecting hole 803. While flushing the photovoltaic module 403, the discharged medium is constrained by the expansion of the second elastic member 604, and gradually converges to the light-transmitting plate 504 area, effectively washing away the dust attached to the surface of the light-transmitting plate 504.

[0069] When the control system detects that the temperature sensor and the pressure sensor are in an unstable state, which is specifically manifested as the elongation of the expansion member 503 being less than the expected elongation according to the outside temperature, this generally indicates that the material blocking the light-transmitting plate 504 is heavy, such as accumulated snow. The accumulated snow not only blocks the light-transmitting plate 504 and prevents light from reaching the photoresistor 502, but also exerts pressure on the expansion member 503, resulting in insufficient elongation.

[0070] Although the light-chasing device 2 can drive the photovoltaic panel 4 to swing in an attempt to make the snow slide down due to gravity, the adhesion between the ice layer under the snow and the photovoltaic panel 4 is often strong, and it is difficult to separate the ice layer from the panel by simple swinging.

[0071] Therefore, when the control system determines that the blocking material is snow and the blocked light-transmitting plate 504 is located in the S2 area, the movable blocks 704 on both sides of the light-transmitting plate 504 in the S2 area are controlled to reciprocate in the fixed tube 602. This movement not only causes the movable blocks 704 to continuously collide with the ends of the fixed tube 602, causing the movable blocks 704 to vibrate, but also the vibration energy is transmitted to the snow through the photovoltaic cell panel 4, loosening the snow and facilitating it to slide off the surface of the photovoltaic cell panel 4.

[0072] At the same time, the movable blocks 704 on both sides of the light-transmitting plate 504 in the S1 region are controlled to move to the third position, so that the conducting groove 705 is connected with the diverter hole 703. Subsequently, the conveying device is activated to pump the medium (antifreeze glass water) into the diverter block 801. As the medium is continuously injected, it flows out through the connecting hole 803 and directly flushes the photovoltaic module 403. Under the dual effects of vibration and flushing, the ice layer under the snow gradually melts, loosens due to vibration, and finally slides off the photovoltaic panel 4.

[0073] This method combining vibration and flushing effectively improves the effect of clearing snow and ice from the photovoltaic panels 4, ensuring that the photovoltaic system can continue to receive light and maintain efficient power generation.

[0074] It should be noted that: the diverter block 801 in this embodiment can be set to a state of rotationally connected with the base 401, and a driving device for driving the diverter block 801 to rotate is provided in the base 401. When the control system confirms that the blocking material is snow, the diverter block 801 is controlled to rotate until the connecting hole 803 and the base 401 are in the same plane. At this time, the medium flowing out of the connecting hole 803 directly acts on the connection between the ice layer and the photovoltaic panel 4. The medium can better enter the gap between the ice layer and the photovoltaic panel 4, so that the ice layer can slide off the photovoltaic panel 4 better. Example 3

[0075] The present invention provides a conversion method for a photoelectric conversion device, the conversion method comprising the following steps: S1. By comparing and analyzing the light intensity data sensed by the photoresistors 502 distributed in different positions, the incident direction of the sunlight is determined. Based on this determination result, the mechanical adjustment function of the light-chasing device 2 is used to dynamically adjust the inclination angle of the photovoltaic panel 4 to ensure that it is continuously aligned with the sunlight source to maximize the light energy capture efficiency.

[0076] S2. During the operation of the photovoltaic panel 4, the resistance fluctuation of the photoresistor 502 mounted on the base 401 is continuously monitored to assess whether the light-transmitting plate 504 is blocked by external objects. The change in resistance value can indirectly reflect the change in light transmittance, thereby determining the blocking state.

[0077] S3. When it is confirmed that the obstruction is dust, the conducting component 7 is started to inject a specific medium into the elastic member in the preset area, causing the elastic member to expand and build a physical barrier. Subsequently, the regulating function of the diversion component 8 is utilized to guide the medium to be discharged in an orderly manner through the connecting hole 803, forming a flushing flow, thereby effectively removing dust accumulation on the surface of the photovoltaic module 403 and the light-transmitting plate 504.

[0078] S4. When it is confirmed that the obstruction is snow, the movable block 704 is driven to reciprocate in the fixed tube 602 to generate high-frequency vibration to loosen the snow physically. At the same time, the diversion component 8 is activated to pressurize and pump the medium into the diversion block 801. The medium is then directly sprayed onto the surface of the photovoltaic module 403 through the connecting hole 803. The flushing force of the medium is used to directly remove the snow, ensuring that the normal operation of the photovoltaic system is not affected.

[0079] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
