Description

Technical Field

[0001] This application relates to the field of photovoltaic cleaning device technology, and in particular to a photovoltaic panel bird droppings cleaning device. Background Technology

[0002] With the construction and expansion of photovoltaic power plants, especially those in complex environments such as tidal flats, the issue of cleaning the surface of photovoltaic panels has become increasingly prominent. Birds frequently move above photovoltaic panels, and their droppings accumulate on the panels, making them difficult to clean and severely impacting power generation efficiency. Prolonged accumulation of bird droppings can also form hot spots, damaging photovoltaic modules and even causing fires. Therefore, it is essential to clean bird droppings from photovoltaic panels promptly.

[0003] Currently available bird droppings cleaning devices have low cleaning efficiency, and some bird droppings still remain on the photovoltaic panels after cleaning, affecting the power generation efficiency of the photovoltaic panels. Summary of the Invention

[0004] This application provides a photovoltaic panel bird droppings cleaning device to improve the cleaning efficiency of photovoltaic panels and prevent bird droppings from remaining on the photovoltaic panels.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include: This application provides a photovoltaic panel bird droppings cleaning device for cleaning bird droppings from photovoltaic panels. The photovoltaic panel bird droppings cleaning device includes: a walking mechanism, a lifting mechanism, a cleaning mechanism, an adsorption mechanism, and an air extraction mechanism. The walking mechanism has a degree of freedom of movement within the photovoltaic panel. The lifting mechanism is installed on the walking mechanism and has a degree of freedom of movement that allows it to move vertically up and down relative to the photovoltaic panel. The cleaning mechanism is installed on the lifting mechanism. The air extraction mechanism is installed on the walking mechanism and is connected to the adsorption mechanism to extract air from the adsorption mechanism. Under the action of the air extraction mechanism, the adsorption mechanism includes an adsorption state and a reset state. When the adsorption mechanism is in the adsorption state, it adsorbs onto the photovoltaic panel to fix the walking mechanism. Under the action of the lifting mechanism, the cleaning mechanism at least partially abuts against the photovoltaic panel. When the adsorption mechanism is in the reset state, it separates from the photovoltaic panel. Under the action of the lifting mechanism, the cleaning mechanism separates from the photovoltaic panel.

[0006] Furthermore, the adsorption mechanism includes an adsorption lifting component and a suction cup. The adsorption lifting component is installed on the walking mechanism, and the suction cup is installed at the end of the adsorption lifting component away from the walking mechanism.

[0007] Furthermore, the suction cup includes a suction cup body and a connector. The suction cup body is connected to the suction lifting component through the connector. An air passage is formed inside the connector, and the air extraction mechanism is connected to the suction cup body through the air passage.

[0008] Furthermore, the cleaning mechanism is connected to the air extraction mechanism, which extracts air from the cleaning mechanism.

[0009] Furthermore, the cleaning mechanism includes a cleaning drum and a drum frame. The cleaning drum is mounted on the drum frame and has a rotational degree of freedom to rotate relative to the drum frame. A scraper is formed inside the drum frame, and the scraper at least partially abuts against the cleaning drum. An air extraction chamber is formed inside the drum frame through the scraper, and the air extraction chamber is connected to the air extraction mechanism.

[0010] Furthermore, the cleaning mechanism also includes a collection box, which is installed on the walking mechanism and connected between the air extraction mechanism and the air extraction chamber.

[0011] Furthermore, a liquid storage chamber is formed inside the roller frame, and the cleaning roller extends at least partially into the liquid storage chamber; along the rotation direction of the cleaning roller, the liquid storage chamber is located at the rear end of the air extraction chamber.

[0012] Furthermore, the cleaning mechanism also includes a lifting frame, which is installed on the traveling mechanism and has the freedom of movement to move up and down relative to the traveling mechanism; the roller frame is connected to the lifting mechanism through the lifting frame.

[0013] Furthermore, the walking mechanism includes a base, a rotating seat, and a mounting box. The rotating seat is mounted on the base and has a rotational degree of freedom relative to the base. The lifting mechanism and the mounting box are both mounted on the rotating seat.

[0014] Furthermore, a mounting groove is formed at the end of the rotating seat facing the base, and the base is at least partially installed into the mounting groove.

[0015] By setting up the adsorption mechanism, on the one hand, it can prevent the bird droppings cleaning device from moving relative to the photovoltaic panel during the cleaning process, ensuring that the cleaning mechanism can continuously clean the fixed position and improve the cleanliness of the photovoltaic panel after cleaning. On the other hand, the adsorption mechanism can provide adsorption force to the bird droppings cleaning device, so that the lifting mechanism can apply a force towards the photovoltaic panel, thereby improving the cleaning efficiency and cleanliness of the photovoltaic panel and preventing bird droppings from remaining on the surface of the photovoltaic panel.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] like Figure 1 As shown, as one implementation, this application provides a photovoltaic panel bird droppings cleaning device. This device can move on the photovoltaic panel 1 and is used to clean the photovoltaic panel 1 of bird droppings, thereby improving the cleanliness of the surface of the photovoltaic panel 1 and thus improving the power generation efficiency of the photovoltaic panel 1.

[0026] The photovoltaic panel bird droppings cleaning device includes a walking mechanism 2, a lifting mechanism 3, a cleaning mechanism 4, an adsorption mechanism 5, and an air extraction mechanism 6. The walking mechanism 2 is used to move the photovoltaic panel bird droppings cleaning device. The lifting mechanism 3 is used to drive the cleaning mechanism 4 to rise and fall, thereby cleaning the photovoltaic panel 1 through the cleaning mechanism 4. The cleaning mechanism 4 is used to clean the bird droppings on the surface of the photovoltaic panel 1. The adsorption mechanism 5 is used to fix the photovoltaic panel bird droppings cleaning device on the photovoltaic panel 1 and to ensure the stability of the cleaning mechanism 4 during the cleaning process. The air extraction mechanism 6 is used to extract air from the cleaning mechanism 4 and the adsorption mechanism 5, to suck up the debris generated by the cleaning mechanism 4, and can also create a vacuum in the adsorption mechanism 5 to adsorb it onto the photovoltaic panel 1.

[0027] Specifically, the walking mechanism 2 has the degree of freedom to move within the photovoltaic panel 1, that is, the walking mechanism 2 can move on the photovoltaic panel 1.

[0028] The lifting mechanism 3 is installed on the walking mechanism 2, and the lifting mechanism 3 has the degree of freedom of movement to lift the photovoltaic panel 1 vertically, that is, the lifting mechanism 3 can lift the photovoltaic panel 1 vertically.

[0029] The cleaning mechanism 4 is installed on the lifting mechanism 3. The lifting mechanism 3 drives the cleaning mechanism 4 to rise and fall. When the photovoltaic panel 1 needs to be cleaned, the lifting mechanism 3 drives the cleaning mechanism 4 to fall, so that the cleaning mechanism 4 at least partially abuts against the photovoltaic panel 1, thereby cleaning the photovoltaic panel 1. When the photovoltaic panel 1 does not need to be cleaned, the lifting mechanism 3 drives the cleaning mechanism 4 to rise, preventing the cleaning mechanism 4 from affecting the movement of the photovoltaic panel bird droppings cleaning device.

[0030] The adsorption mechanism 5 is installed on the walking mechanism 2. When the photovoltaic panel 1 needs to be cleaned by the cleaning mechanism 4, the adsorption mechanism 5 adsorbs onto the photovoltaic panel 1, ensuring that the photovoltaic panel bird droppings cleaning device can be stably fixed on the photovoltaic panel 1, thereby ensuring that the cleaning mechanism 4 can stably clean the photovoltaic panel 1.

[0031] During the cleaning process, the cleaning mechanism 4 descends via the lifting mechanism 3 to ensure that the cleaning mechanism 4 can apply a certain pressure toward the photovoltaic panel 1. Through the setting of the adsorption mechanism 5, an adsorption force can be provided to the photovoltaic panel bird droppings cleaning device, thereby preventing the photovoltaic panel bird droppings cleaning device from separating from the photovoltaic panel 1.

[0032] The air extraction mechanism 6 is installed on the walking mechanism 2 and is connected to the adsorption mechanism 5. The air extraction mechanism 6 can be used to extract air from the adsorption mechanism 5.

[0033] When the adsorption mechanism 5 comes into contact with the photovoltaic panel 1, the air extraction mechanism 6 works, creating a negative pressure between the adsorption mechanism 5 and the photovoltaic panel 1, thereby adsorbing the adsorption mechanism 5 onto the photovoltaic panel 1.

[0034] Under the action of the suction mechanism 6, the adsorption mechanism 5 includes an adsorption state and a reset state. When the adsorption mechanism 5 is in the adsorption state, the adsorption mechanism 5 is attracted to the photovoltaic panel 1 to fix the walking mechanism 2. Under the action of the lifting mechanism 3, the cleaning mechanism 4 is at least partially in contact with the photovoltaic panel 1 so as to clean the photovoltaic panel 1 through the cleaning mechanism 4.

[0035] When the adsorption mechanism 5 is in the reset state, the adsorption mechanism 5 is separated from the photovoltaic panel 1. Under the action of the lifting mechanism 3, the cleaning mechanism 4 is separated from the photovoltaic panel 1, so that the photovoltaic panel bird droppings cleaning device can move on the photovoltaic panel 1.

[0036] like Figure 2 , Figure 3 and Figure 6 As shown, in one implementation, the walking mechanism 2 includes a base 201, a rotating seat 202 and a mounting box 203. The rotating seat 202 is mounted on the base 201 and has a rotational degree of freedom relative to the base 201. The lifting mechanism 3 and the mounting box 203 are both mounted on the rotating seat 202.

[0037] Specifically, four mounting feet 2011 are formed on the base 201, and a roller 204 is installed on each mounting foot 2011. Two of the rollers 204 are connected to a drive motor 205. The drive motor 205 drives the rollers 204 to rotate, thereby driving the base 201 to move on the photovoltaic panel 1.

[0038] It should be noted that the base 201 can move straight or turn by changing the speed difference between the two drive motors 205.

[0039] As one implementation, the end of the rotating base 202 facing the base 201 has a mounting groove 2021, and the base 201 is at least partially installed in the mounting groove 2021, thereby improving the connection stability between the rotating base 202 and the base 201.

[0040] Meanwhile, a bearing is installed in the mounting slot 2021, allowing the rotating seat 202 to rotate stably relative to the base 201.

[0041] As one implementation, the walking mechanism 2 also includes a rotary drive component, which includes a rotary motor 206, a drive gear 207, and a gear ring 208. The rotary motor 206 is mounted on the rotary base 202, the drive gear 207 is mounted on the motor shaft of the rotary motor 206, and the gear ring 208 is mounted on the base 201, and the drive gear 207 meshes with the gear ring 208.

[0042] The rotating seat 202 is driven to rotate relative to the base 201 by a rotating drive component.

[0043] Specifically, a circular base groove 2012 is formed in the middle of the base 201, and the toothed ring 208 is installed in the base groove 2012.

[0044] As one implementation method, the lifting mechanism 3 is installed on the top of the lifting box 203.

[0045] The lifting mechanism 3 includes a lifting cylinder 301 and a lifting connecting rod 302. The lifting cylinder 301 is fixed to the top of the lifting box 203, and the lifting connecting rod 302 is installed on the cylinder shaft of the lifting cylinder 301. The cleaning mechanism 4 is connected to the bottom of the lifting connecting rod 302.

[0046] The lifting electric cylinder 301 drives the lifting connecting rod 302 to move up and down, thereby driving the cleaning mechanism 4 to move up and down.

[0047] like Figure 2 and Figure 4 As shown, in one implementation, the cleaning mechanism 4 is connected to the air extraction mechanism 6, and the air extraction mechanism 6 extracts air from the cleaning mechanism 4.

[0048] As one implementation, the cleaning mechanism 4 includes a cleaning roller 401, a roller frame 402, and a lifting frame 404. The cleaning roller 401 is mounted on the roller frame 402 and has a rotational degree of freedom to rotate relative to the roller frame 402. The surface of the photovoltaic panel 1 is cleaned by the cleaning roller 401.

[0049] The roller frame 402 is installed at the bottom of the lifting frame 404. The roller frame 402 is connected to the lifting connecting rod 302 through the lifting frame 404 so that the cleaning roller 401 can be raised and lowered under the action of the lifting electric cylinder 301.

[0050] Specifically, a drum cavity is formed inside the drum frame 402, and the cleaning drum 401 is rotatably installed inside the drum cavity.

[0051] As one implementation, a drive motor is installed on the roller frame 402, and the drive motor is connected to the cleaning roller 401 to drive the cleaning roller 401 to rotate.

[0052] In one implementation, a scraper 4021 and a liquid storage plate 4024 are formed inside the roller frame 402, and the roller cavity is divided into an air extraction cavity 4022 and a liquid storage cavity 4023 by the scraper 4021 and the liquid storage plate 4024.

[0053] The air extraction chamber 4022 is located above the scraper 4021 and is used to store foreign objects generated during bird droppings cleaning. The liquid storage chamber 4023 is located between the scraper 4021 and the liquid storage plate 4024 and is used to store liquid for cleaning the photovoltaic panel 1.

[0054] Specifically, the scraper 4021 at least partially abuts against the cleaning drum 401, and the air extraction chamber 4022 is connected to the air extraction mechanism 6. The air extraction mechanism 6 extracts air from the air extraction chamber 4022 to collect the foreign objects scraped off by the scraper 4021, preventing the foreign objects from re-adhering to the cleaning drum 401, thereby improving the cleanliness of the cleaning drum 401.

[0055] It should be noted that the end of the scraper 4021 facing the cleaning roller 401 has a rounded head structure to prevent the scraper 4021 from damaging the cleaning roller 401. At the same time, the surface of the cleaning roller 401 is a velvet layer to facilitate the adhesion of liquid used for cleaning the photovoltaic panel 1 and foreign matter generated from cleaning bird droppings to the cleaning roller 401.

[0056] In one implementation, the cleaning roller 401 extends at least partially into the liquid storage chamber 4023 so that the cleaning roller 401 can pick up the liquid in the liquid storage chamber 4023, thereby facilitating the cleaning roller 401 to clean the photovoltaic panel 1.

[0057] Along the rotation direction of the cleaning drum 401, the liquid storage chamber 4023 is located at the rear end of the air extraction chamber 4022, that is, the rotation direction of the cleaning drum 401 is from the scraper 4021 to the liquid storage plate 4024.

[0058] The scraper 4021 scrapes away the contaminated liquid attached to the cleaning roller 401 and the foreign matter generated from cleaning bird droppings. Then, the clean liquid is applied to the surface of the cleaning roller 401 through the liquid storage chamber 4023, so as to improve the cleaning degree of the photovoltaic panel 1.

[0059] As one implementation, the cleaning mechanism 4 also includes a collection box 403, which is installed on the walking mechanism 2 and connected between the air extraction mechanism 6 and the air extraction chamber 4022. The collection box 403 collects the contaminated liquid attached to the cleaning roller 401 and the foreign matter generated during the cleaning of bird droppings.

[0060] Specifically, the collection box 403 has a hollow structure, and a filter screen 4031 is formed inside the collection box 403. The filter screen 4031 is used to prevent foreign objects from moving into the air extraction mechanism 6.

[0061] The collection box 403 is divided into an upper and a lower layer by a filter screen. The lower side wall of the collection box 403 is connected to the air extraction chamber 4022, and the top of the upper layer of the collection box 403 is connected to the air extraction mechanism 6.

[0062] As one implementation, the cleaning mechanism 4 also includes a liquid storage box 405, which is connected to the liquid storage chamber 4023 via a hose. A delivery pump is installed in the liquid storage box 405 to deliver the liquid in the liquid storage box 405 to the liquid storage chamber 4023 so that the cleaning roller 401 can pick up the liquid in the liquid storage chamber 4023.

[0063] In one implementation, the cleaning roller 401 extends at least partially into the liquid storage chamber 4023 so that the cleaning roller 401 can pick up the liquid in the liquid storage chamber 4023.

[0064] As one implementation, the cleaning mechanism 4 also includes a lifting frame 404, which is installed on the traveling mechanism 2 and has a degree of freedom of movement to move up and down relative to the traveling mechanism 2. The roller frame 402 is connected to the lifting mechanism 3 through the lifting frame 404.

[0065] Specifically, the lifting frame 404 is connected to the side wall of the lifting box 203 via a slide rail slider. At the same time, a guide rod 4041 is connected to the bottom of the lifting frame 404, and the guide rod 4041 is connected to the rotating seat 202 to ensure that the lifting frame 404 can be stably raised and lowered relative to the traveling mechanism 2.

[0066] like Figure 2 and Figure 5 As shown, in one implementation, the adsorption mechanism 5 includes an adsorption lifting component 501 and a suction cup 502. The adsorption lifting component 501 is installed on the walking mechanism 2, and the suction cup 502 is installed at the end of the adsorption lifting component 501 away from the walking mechanism 2. The adsorption lifting component 501 drives the suction cup 502 to rise and fall, so that the suction cup 502 comes into contact with the surface of the photovoltaic panel 1, thereby adsorbing the suction cup 502 onto the photovoltaic panel 1.

[0067] The adsorption lifting component 501 is an electric cylinder.

[0068] As one implementation, the suction cup 502 includes a suction cup body 5021 and a connector 5022, with the suction cup body 5021 connected to the suction lifting component 501 via the connector 5022.

[0069] An air passage 50221 is formed inside the connector 5022, and the suction mechanism 6 is connected to the suction cup body 5021 through the air passage 50221.

[0070] When the suction cup body 5021 comes into contact with the photovoltaic panel 1, the air extraction mechanism 6 works, which reduces the air pressure between the suction cup body 5021 and the photovoltaic panel 1, thereby fixing the adsorption mechanism 5 to the photovoltaic panel 1, and then fixing the photovoltaic panel bird droppings cleaning device to the photovoltaic panel 1.

[0071] After the bird droppings cleaning device for the photovoltaic panel is finished cleaning, the reversing valve of the air extraction mechanism 6 is activated, which connects the air passage 50221 to the air, thereby depressurizing the suction cup body 5021. Then, the suction cup body 5021 is lifted by the suction lifting component 501, so that the bird droppings cleaning device for the photovoltaic panel can move on the photovoltaic panel 1.

[0072] As one implementation method, the mounting box 203 has a hollow structure, and the air extraction mechanism 6 and electronic components such as circuit boards are installed inside the mounting box 203.

[0073] As one implementation, the air extraction mechanism 6 includes an air extraction pump 601, a reversing valve 602, a first pipeline 603 and a second pipeline 604. The reversing valve 602 is installed on the air extraction pump 601. The adsorption mechanism 5 is connected to the reversing valve 602 through the first pipeline 603, and the cleaning mechanism 4 is connected to the reversing valve 602 through the second pipeline 604.

[0074] During the bird droppings cleaning process of the photovoltaic panel bird droppings cleaning device, the working steps of the air extraction mechanism 6 are as follows.

[0075] (1) When the reversing valve 602 is working, the air pump 601 is connected to the adsorption mechanism 5. The air pump 601 draws air from the adsorption mechanism 5, so that the adsorption mechanism 5 is adsorbed on the photovoltaic panel 1.

[0076] (2) After the adsorption mechanism 5 is adsorbed on the photovoltaic panel 1, the reversing valve 602 works, which disconnects the air pump 601 from the adsorption mechanism 5, so that the adsorption mechanism 5 remains adsorbed on the photovoltaic panel 1.

[0077] (3) The cleaning mechanism 4 cleans the photovoltaic panel 1. The reversing valve 602 works to connect the air pump 601 to the air extraction chamber 4022, and sucks the polluted liquid and foreign matter generated from cleaning bird droppings into the collection box 403.

[0078] (3) After cleaning, the reversing valve 602 is activated, which disconnects the air pump 601 from the air extraction chamber 4022 and connects the first pipeline 603 to the atmosphere, thereby depressurizing the adsorption mechanism 5.

[0079] like Figure 2 As shown, as one implementation method, the photovoltaic panel bird droppings cleaning device also includes a monitor 7, which is installed above the mounting box 203 and is used to acquire images of the surface of the photovoltaic panel 1 so that bird droppings on the surface of the photovoltaic panel 1 can be identified manually or by an image recognition system.

[0080] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.

[0081] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
