However, traditional dust removal devices have some shortcomings in practical applications. Specifically, firstly, traditional dust removal devices mostly use water washing to clean sand and dust from the surface of photovoltaic panels, which poses problems such as water scarcity and high water transportation costs for photovoltaic equipment built in water-scarce desert areas; secondly, traditional dust removal devices often require manual on-site operation to clean sand and dust, which poses a great risk due to the large area and complex terrain of photovoltaic fields; finally, conventional photovoltaic panel dust removal devices can easily cause secondary pollution to photovoltaic panels during operation due to problems such as the inability of the brushes of the dust removal device to clean thoroughly and uneven water spraying. Utility Model Content

[0003] The purpose of this utility model is to address the technical problems existing in the background art by providing a timed-start automatic wind-powered dust removal device driven by the self-generated power of photovoltaic modules. To achieve the above objective, this utility model is implemented through the following technical solution:

[0004] An automatic dust removal system powered by a self-generated photovoltaic module includes a photovoltaic panel and a photovoltaic panel support. The photovoltaic panel support is erected on the ground, with the photovoltaic panel fixed at an angle above it. A photovoltaic panel cleaning system for cleaning dust from the surface of the photovoltaic panel is fixed on both sides of the photovoltaic panel. The photovoltaic panel cleaning system includes a dust removal device, a dust collection device, and a power supply control device. The power supply control device uses the electrical energy provided by the photovoltaic conversion of the photovoltaic panel to periodically drive the dust removal device on one side of the photovoltaic panel to blow the dust on the photovoltaic panel to the dust collection device on the other side of the photovoltaic panel. For the dust blown by the dust removal device, the dust collection device separates the wind energy and dust before sending the wind energy back to the dust removal device, thus forming an integrated blowing and suction photovoltaic panel cleaning system.

The integrated blower and suction fan are connected in sequence to the main air supply pipe for the air knife, the connecting branch pipe for the air knife, and the side of the dust removal air knife through the fan connecting pipe. The length of the dust removal air knife is consistent with the width of the photovoltaic panel, and it is installed on one side of the photovoltaic panel through several air knife fixing bases. One end of the reciprocating push rod is connected to the air knife fixing base, and the other end is axially connected to the dust removal air knife, which is used to drive the dust removal air knife to reciprocate.

[0006] Preferably, the blower-suction integrated fan is a high-pressure, high-speed, large-volume centrifugal turbofan fan.

[0007] Preferably, the dust collection device includes a dust collection hood, a dust collection hood base, a dust collection hood connecting branch pipe, a vacuum cleaner suction main pipe, a dust collector inlet connecting pipe, and a cyclone dust collector. The dust collection hood has a wide-mouth guide channel structure, the length of which is consistent with the width of the photovoltaic panel, and is fixed to the other side of the photovoltaic panel by several dust collection hood bases. The dust collection hood is connected to the vacuum cleaner suction main pipe, the dust collector inlet connecting pipe, and the cyclone dust collector in sequence through the dust collection hood connecting branch pipe. The cyclone dust collector is used to adsorb and separate sand and dust and wind energy on the photovoltaic panel.

[0008] Preferably, the cyclone dust collector is a three-stage filtration dust removal device comprising a dust screen, a cyclone separator, and a dust collection bag.

[0009] Preferably, the diameter of the main air supply pipe of the air knife is larger than that of the connecting branch pipe of the air knife, and the diameter of the main suction pipe of the vacuum cleaner is larger than that of the connecting branch pipe of the vacuum hood so as to serve as a pressure chamber. In addition, except for the connecting branch pipe of the air knife which is made of cold-resistant and high-temperature resistant flexible hose, all other pipes are made of rigid high-pressure resistant pipe.

[0010] Preferably, the power supply control device includes an inverter, a reciprocating push rod controller, a fan controller, a DC cable, and an AC cable. The DC power generated by the photovoltaic panel is transmitted to the reciprocating push rod controller and the reciprocating push rod via the DC cable. The reciprocating push rod controller can be used to regulate the reciprocating rotation of the dust removal air knife. At the same time, the DC power generated by the photovoltaic panel is converted into AC power by the inverter and then transmitted to the fan controller and the integrated blower and suction fan via the AC cable. The fan controller can be used to control the start and stop of the integrated blower and suction fan.

[0011] Preferably, it also includes a timer controller, which can be set to start and stop the reciprocating push rod controller and the fan controller at regular intervals to realize the automatic timed operation of the photovoltaic panel cleaning system.

[0027] The following is in conjunction with the appendix Figure 1-10 The embodiments of this utility model will be described in further detail below.

[0028] like Figure 1-6 As shown, it includes a dust removal device 4 and a dust collection device 5. The dust removal device 4 includes a blower and a suction fan 401, a fan connecting pipe 402, a main air supply pipe for the air knife 403, a connecting branch pipe for the air knife 404, a dust removal air knife 405, an air knife fixing base 406, a reciprocating push rod 407, a screw 1 408, a screw 2 409, a push rod rotating shaft 410, and a rotating shaft 411. The blower 401 is connected to one end of a bent rigid high-pressure resistant blower connecting pipe 402. The other end of the blower connecting pipe 402 is connected to a rigid high-pressure resistant air knife supply main pipe 403, which is larger than its inner diameter and placed parallel to the dust removal air knife 405. Several cold-resistant and high-temperature resistant soft air knife connecting branch pipes 404 are vertically and equidistantly arranged on the air knife supply main pipe 403. Each air knife connecting branch pipe 404 is connected to a dust removal air knife 405. Each dust removal air knife 405 is connected to the air knife fixing base 406 through a rotating shaft 411. The air knife fixing base 406 is connected to the edge of the photovoltaic panel 1 through three screws 408. The upper end of the reciprocating push rod 407 is connected to the dust removal air knife 405 through the push rod rotating shaft 410, and the lower end is connected to the air knife fixing base 406 through screws 409.

[0029] The dust collection device 5 includes a dust collection hood 501, a dust collection hood base 502, a dust collection hood connecting branch pipe 503, a vacuum cleaner suction main pipe 504, a dust collector inlet connecting pipe 505, a cyclone dust collector 506, a dust filter 507, a cyclone separator 508, a dust collection bag 509, screws 3 and 4 511. The dust collection hoods 501, with a wide-mouth guide channel structure designed in an equal number to the number of dust removal air knives 405, are located above the entire dust collection device 5. Each dust collection hood 501 is connected to the edge of the photovoltaic panel 1 via screws 3 and 510. Each dust collection hood 501 is also indirectly connected to the oblique edge of the photovoltaic panel 1 via the dust collection hood base 502 and screws 4 511. The lower side of each dust collection hood 501 is connected to equidistantly arranged rigid, high-pressure resistant dust collection hood connecting branch pipes 503. Several dust collection hood connecting branch pipes... The pipe 503 is vertically connected to a rigid, high-pressure resistant vacuum cleaner suction main pipe 504 placed parallel to the vacuum hood 501. The lower end of the vacuum cleaner suction main pipe 504 is connected to a bent rigid, high-pressure resistant dust collector inlet connection pipe 505. The dust collector inlet connection pipe 505 is connected to a cyclone dust collector 506. Inside the cyclone dust collector 506, there is a dustproof net 507. Below the dustproof net 507 are a cyclone separator 508 and a dust collection bag 509, respectively.

[0030] The cyclone dust collector 506 is connected to the blower-suction integrated fan 401 through the blower-dust collector connecting pipe 7. The dust blown in by the dust removal air knife 405 passes through the dust suction hood 501, the dust suction hood connecting branch pipe 503, the dust collector suction main pipe 504 and the dust collector inlet connecting pipe 505 to reach the cyclone dust collector 506. The cyclone dust collector 506 can separate the wind energy and the dust and transport the wind energy to the blower-suction integrated fan 401 for reuse through the blower-dust collector connecting pipe 7.

[0031] like Figure 7 As shown, it includes a photovoltaic panel 1, a dust removal air knife 405, an air knife fixing base 406, a reciprocating push rod 407, a screw 409, a push rod rotating shaft 410, a rotating shaft 411, and a DC cable 604. A DC cable 604 connects to one corner of a reciprocating push rod 407. One end of the reciprocating push rod 407 is connected to the air knife fixing base 406 via screw 409, and the other end is connected to the dust removal air knife 405 via the push rod rotating shaft 410. When the DC cable 604 is energized, the reciprocating push rod 407 can extend and retract to make linear motion, thereby driving the dust removal air knife 405 to swing back and forth around the rotating shaft 411 of the air knife fixing base 406. When the reciprocating push rod 407 extends, it drives the dust removal air knife 405 to swing downward, covering one side of the photovoltaic panel 1. When the reciprocating push rod 407 retracts, it drives the dust removal air knife 405 to swing upward, covering the other side of the photovoltaic panel 1. In this way, the dust removal air knife 405, driven by the reciprocating push rod 407, realizes the up and down reciprocating swing of the air knife nozzle, which thoroughly removes dust and sand particles from the surface of the photovoltaic panel 1.

[0032] like Figure 8-9As shown, the device includes a photovoltaic panel 1, a photovoltaic panel support 2, horizontal frames 801, vertical frames 802, a blower / suction fan 401, and a cyclone dust collector 506. The photovoltaic panel support 2 is erected on the ground, with the photovoltaic panel 1 fixed at an angle above it. Four horizontal frames 801 are symmetrically fixed at equal intervals in the middle of the photovoltaic panel support 2. Four vertical frames 802 are symmetrically fixed at equal intervals on the left side of the horizontal frames 801 in the vertical direction. The blower / suction fan 401 is fixed to the four vertical frames 802 and then to the photovoltaic panel support 2. The cyclone dust collector 506 is fixed to the horizontal frames 801 and then to the photovoltaic panel support 2.

[0033] like Figure 10 As shown, the system includes an inverter 601, a reciprocating push rod controller 602, a fan controller 603, a DC cable 604, an AC cable 605, and a timer controller 606. The DC power generated by the photovoltaic panel 1 is transmitted to the reciprocating push rod controller 602 and the reciprocating push rod 407 via the DC cable 604, thus forming a complete circuit. By controlling the reciprocating push rod controller 602, the extension and retraction of the reciprocating push rod 407 can be adjusted, thereby controlling the rotation of the dust removal air knife 405. At the same time, the DC power generated by the photovoltaic panel 1 is converted into AC power by the inverter 601 and then transmitted to the fan controller 603 and the integrated blower and suction fan 401 via the AC cable 605, forming a complete circuit. By controlling the fan controller 603, the integrated blower and suction fan 401 can be started and stopped. In addition, the timer controller 606 can control the reciprocating push rod controller 602 and the fan controller 603 to start and stop at set times to achieve automatic timed operation of the photovoltaic panel cleaning system 3.

[0034] The specific working principle is as follows:

[0035] Staff set a timer controller 606 to automatically drive the photovoltaic panel cleaning system 3 to clean the dust on the photovoltaic panel 1 at a certain time every noon. After the designated time, the timer controller 606 activates the reciprocating push rod controller 602 and the fan controller 603. The DC power generated by the photovoltaic panel 1 is converted into AC power by the inverter 601 and then transmitted to the blower 401 via the AC cable 605. The blower 401 converts the electrical energy into wind power and transmits it through the fan connecting pipe 402 to the air knife supply main pipe 403, and then to the air knife connecting branch pipe 404, finally reaching the dust removal air knife 405. At the same time, the DC power generated by the photovoltaic panel 1 is transmitted through the DC cable 604 to the reciprocating push rod 407, which drives the reciprocating push rod 407 to rotate the dust removal air knife 405 back and forth, blowing away the dust on the photovoltaic panel 1.

[0036] The dust removal air knife 405 can blow the sand and dust on the photovoltaic panel 1 to the dust collection hood 501. The sand and dust entering the dust collection hood 501, driven by the wind, can reach the cyclone dust collector 506 through the dust collection hood connecting branch pipe 503, the vacuum cleaner suction main pipe 504 and the dust collector air inlet connecting pipe 505. Under the action of the dust screen 507 in the cyclone dust collector 506, large particles of sand and dust and impurities are intercepted. The wind energy and medium-sized particles of impurities enter the cyclone separator 508 for centrifugal separation. The separated wind energy is filtered again through the dust collection bag 509 and then transported to the blower-suction integrated fan 401 for reuse through the fan dust collector connecting pipe 7. The medium-sized particles of impurities slide down the side wall of the cyclone dust collector 506 to the ground, and the staff can clean the dust on the ground regularly.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
