Description

Technical Field

[0001] The utility model belongs to the field of cleaning and dust removal of photovoltaic equipment, and particularly relates to an air-powered suspended photovoltaic cleaning robot. Background Technique

[0002] Currently, most photovoltaic power stations are cleaned manually. Manual cleaning is arduous in cold winters and scorching summers, and it is even more difficult to find workers for construction in desolate gobi and vast deserts. To solve the problem of photovoltaic panel cleaning, cleaning robots have emerged in large numbers on the market, and the designs of various products are different, each with its own advantages and disadvantages. However, most of the existing cleaning robots for photovoltaic panel cleaning use water washing. Considering that large-scale photovoltaic power stations are generally built in areas with sufficient sunlight but lacking water such as gobi and deserts, water washing is obviously impractical for them. In addition, there is also the problem of "hitting the panel" in the industry of photovoltaic cleaning. When the cleaning machine runs on an uneven road surface, it will inevitably cause the cleaning module to hit the photovoltaic panel, resulting in damage to the photovoltaic panel. Therefore, it is necessary to design a new type of photovoltaic cleaning robot with a novel structure. Content of the Utility Model

[0003] The utility model provides an air-powered suspended photovoltaic cleaning robot, aiming to overcome the above-mentioned deficiencies existing in the prior art.

[0004] The technical solution for the utility model to solve the above technical problems is as follows: An air-powered suspended photovoltaic cleaning robot, which includes a box body. A power supply module, a dust removal fan module, a propulsion fan module, a limit guiding wheel module and an intelligent control module are arranged on the box body. The limit guiding wheel module is arranged on the opposite sides of the bottom of the box body and is used to abut and cooperate with the upper edge and the lower edge of the outer frame of the inclined photovoltaic panel to ensure that the box body moves left and right on the outer frame of the photovoltaic panel after the propulsion fan module is started. The dust removal fan module is used to blow air to remove dust on the upper surface of the photovoltaic panel. The propulsion fan module is used to push the box body to move left and right on the photovoltaic panel. The power supply module is electrically connected to the dust removal fan module, the propulsion fan module and the intelligent control module.

[0005] On the basis of the above technical solution, the utility model can be further improved as follows.

[0006] Further, the power supply module includes a lithium battery pack arranged in the box body, and a charging interface electrically connected to the lithium battery pack is arranged on the box body.

[0007] Further, the dust removal fan module includes a plurality of blowing and dust removing air blowers with air outlets arranged on the bottom wall of the box body.

[0008] Further, when the box body is placed on the outer frame of the photovoltaic panel through the limit guiding wheels, the blowing and dust removing air blower blows air vertically downward through the air outlet.

[0009] Furthermore, the propulsion fan module includes a plurality of thrust fans with air outlets provided on the left and right side walls of the box body.

[0010] Furthermore, an air inlet for facilitating the dust removal fan module and the propulsion fan module to suck air is provided at the top of the box body.

[0011] Furthermore, the limit guiding wheel module includes connecting frames fixed at the four corners of the bottom of the box body. A side pressure limit wheel and a top pressure limit wheel are rotatably connected to each connecting frame. The side pressure limit wheel abuts against the side surface of the upper or lower edge of the outer frame of the photovoltaic panel, and the top pressure limit wheel abuts against the top surface of the upper or lower edge of the outer frame of the photovoltaic panel.

[0012] Furthermore, an intelligent recognition module is further included. The intelligent recognition module includes cameras provided at the bottom or the left and right sides of the box body, and the cameras are used to collect images of the photovoltaic panels below.

[0013] Furthermore, a dust suction module is further included. The dust suction module includes a dust suction fan and a detachable ash storage hopper, and the air inlet of the dust suction fan is provided on the side wall or the bottom of the box body.

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

[0015] The air suspension photovoltaic cleaning robot provided by the present utility model is placed on the outer frame of the photovoltaic panel to be cleaned through the limit guiding wheel module provided on the upper and lower side edges of the box body. When cleaning, the dust removal fan module on the box body is started to blow downward, and at the same time, the propulsion fan module is started to provide a thrust to move the box body left and right along the outer frame of the photovoltaic panel. The downward blowing of the dust removal fan module not only blows and cleans the upper surface of the photovoltaic panel, but also provides a certain upward buoyancy to the box body to make the box body in a micro-suspension state, reducing the pressure on the upper and lower edges of the outer frame of the photovoltaic panel, that is, reducing the friction effect, ensuring that the box body can easily move back and forth left and right on the outer frame of the photovoltaic panel under the action of the propulsion fan module, so as to better complete the blowing and dust removal effect on the photovoltaic panel.

[0016] The air suspension photovoltaic cleaning robot provided by the present utility model has an intelligent control module, which can control the start, stop and rotation speed of the dust removal fan and the propulsion fan module according to the set program or manual remote control, so as to realize the full-automatic or semi-automatic high-efficiency dust removal and cleaning of the photovoltaic panel, greatly saving labor costs; using wind power for dust removal to overcome the shortage of water shortage or inability to use water washing for dust removal in the installation area of the photovoltaic panel.

[0023] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0024] In the description of the present utility model, if terms indicating directions such as "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc. are used, the directions or positional relationships indicated are based on the directions or positional relationships shown in the attached drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as a limitation to the present utility model.

[0025] As Figures 1 to 4 shown, the present utility model provides an aerodynamic suspension photovoltaic cleaning robot, which includes a box body 1. A power module, a dust-removing fan module, a propulsion fan module, a limit guiding wheel module, and an intelligent control module are provided on the box body 1. The limit guiding wheel module is provided on the opposite sides of the bottom of the box body 1 and is used to abut and cooperate with the upper and lower edges of the inclined outer frame 2 of the photovoltaic panel to ensure that the box body 1 moves left and right on the outer frame 2 of the photovoltaic panel after the propulsion fan module is started. The dust-removing fan module is used to blow air to remove dust from the upper surface of the photovoltaic panel. The propulsion fan module is used to push the box body 1 to move left and right on the photovoltaic panel. The power module is electrically connected to the dust-removing fan module, the propulsion fan module, and the intelligent control module.

[0026] It should be noted that the intelligent control module can control the power module to supply power or cut off power to the dust removal fan module and the propulsion fan module, and can also control the rotation speed of the fans in the dust removal fan module and the propulsion fan module. The control method can be automatic control according to a set program. For example, the cleaning robot can be automatically started regularly (every day or every few days) to move left and right on the surface of the photovoltaic panel for at least one reciprocating blow-dust operation. Or the start / stop and rotation speed gear control of the above-mentioned cleaning and dust removal actions can be manually controlled through a remote control.

[0027] In an embodiment of the present invention, the power module includes a lithium battery pack disposed in the box body 1, and a charging interface electrically connected to the lithium battery pack is provided on the box body 1.

[0028] It should be noted that in order to facilitate the long-term use of the cleaning robot without relying on an external power source after being equipped with corresponding equipment on the photovoltaic panel, a charging mechanism can be set on the photovoltaic panel. When charging is required, the charging plug of the charging mechanism can be directly inserted into the charging interface of the lithium battery pack by using the corresponding photovoltaic panel for charging.

[0029] In an embodiment of the present invention, the dust removal fan module includes a plurality of blow-dust air blowers 3 whose air outlets are provided on the bottom wall of the box body 1.

[0030] It can be understood that the blow-dust air blower can be understood in a broad sense, including an air pump capable of providing a high-speed jet airflow.

[0031] In an embodiment of the present invention, when the box body 1 is placed on the outer frame 2 of the photovoltaic panel through the limit guide wheels, the blow-dust air blower 3 blows air vertically downward through the air outlet.

[0032] It should be noted that the angle formed between the vertically downward air blowing and the inclined photovoltaic panel is just an angle that is easy to blow off the accumulated dust, and the dust cleaning efficiency is high. At the same time, the reaction force of the air blowing on the cleaning robot by the blow-dust air blower is also vertically upward, which can better counteract the self-gravity of the cleaning robot and better achieve the effect of micro-suspension to reduce the pressure on the outer frame of the photovoltaic panel.

[0033] In an embodiment of the present invention, the propulsion fan module includes a plurality of thrust air blowers 4 whose air outlets are provided on the left and right side walls of the box body 1.

[0034] It can be understood that the thrust air blower can be a cross-flow fan or other fans. In the present invention, it can also be understood in a broad sense to include an air pump capable of providing a jet airflow.

[0035] In an embodiment of the present invention, an air inlet 5 is provided at the top of the box body 1 to facilitate the dust removal fan module and the propulsion fan module to suck air.

[0036] It is understandable that the air inlet is not limited to being located at the top of the box, but can also be located at the upper side of the box. Since dust is blown downward, the air inlet should not be located at the lower side of the box without effective measures. To prevent water from entering the box, a rain cap or grille can be installed at the air inlet.

[0037] In one embodiment of the present invention, Figure 2 As shown, the limiting guide wheel module includes a connecting frame 6 fixed to the four corners of the bottom of the box body 1, and each of the connecting frames 6 is rotatably connected with a side pressure limiting wheel 7 and a top pressure limiting wheel 8. The side pressure limiting wheel 7 abuts against the side of the upper edge or the lower edge of the photovoltaic panel outer frame 2, and the top pressure limiting wheel 8 abuts against the top surface of the upper edge or the lower edge of the photovoltaic panel outer frame 2.

[0038] It should be noted that the two side pressure limit wheels on the upper and lower sides generally do not abut against the upper and lower edges of the photovoltaic panel outer frame at the same time. A certain gap should be reserved so that the cleaning robot has an appropriate upward micro-suspension gap when it is subjected to the reaction force generated by blowing and dust removal.

[0039] In one embodiment of the utility model, an intelligent recognition module is also included. The intelligent recognition module includes a camera arranged at the bottom or the left and right sides of the box body 1, and the camera is used to collect images of the photovoltaic panels below.

[0040] It should be noted that the surface image of the photovoltaic panel captured by the camera can be transmitted to the image processing module for comparison with the standard image, so as to automatically compare and find the damaged area of the photovoltaic panel.

[0041] In one embodiment of the present invention, a dust suction module is further included. The dust suction module includes a dust suction fan and a detachable ash storage hopper. The air inlet of the dust suction fan is arranged on the side wall or the bottom of the box body 1.

[0042] It should be noted that in order to avoid the problem of dust dispersion during cleaning as much as possible, the above-mentioned dust suction module can be additionally provided. While blowing dust to remove and clean, the dust suction module sucks in the dust-laden airflow and accumulates the dust in the airflow in the dust storage hopper.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
