Description

  The present invention relates to a cleaning device for cleaning a photovoltaic power generation panel that generates power using solar energy, and in particular, quickly and entirely covers the entire surface of a solar panel installed in a place where a lot of dust such as sand dust is generated. The present invention relates to a photovoltaic panel cleaning apparatus that performs automatic cleaning efficiently and reliably.

  Conventionally, power generation facilities using solar power generation panels have been operated in various places, and large-scale solar power for commercial use to generate large-scale power generation from small panels intended for use in general households. There are various sizes, shapes, specifications, and standards for power generation panels. Particularly in commercial power generation facilities, large-capacity solar power generation panels with high power generation efficiency are installed.

  The basic principle of photovoltaic power generation is to use the photovoltaic effect that utilizes the characteristics of semiconductors, and sunlight is the energy source. In other words, an electromotive force is generated by irradiating light to the panel surface that receives sunlight. Therefore, even in a high-performance power generation panel with high power generation efficiency, light is blocked by dirt such as adhesion of dust and dirt. The power generation efficiency may be reduced, or in the worst case, it may be impossible to generate power.

  In recent years, a technique for effectively generating power used in a building by effectively utilizing a space such as a rooftop of a building has been penetrating. On the other hand, for the purpose of performing large-scale power generation such as power sales, a large area of land is secured and power generation equipment is often installed. The ideal installation location is one where there is little obstruction to sunlight, but such location is limited to some extent. Solar panels are often installed in forests, plains, and water surfaces, but they are ideal places where there are no obstructions such as sand dunes and deserts because there are no sunshine hours or obstructions. It is believed that.

  However, when installed in a sand dune or desert, the sand particles are very light, so the sand that has been raised by the wind adheres to the surface of the photovoltaic panel. Sand can be easily swept away, but the sand particles are extremely small and light, so that only the sweeping will move the panel surface, making it difficult to remove completely. It was.

  The applicant who is the inventor of the present invention is also the applicant of JP-A-2014-22524. In this invention, it consists of a moving frame consisting of a pair of upper and lower fixed guide rails, a pair of left and right moving guide rails, and a cleaning body mounted on the moving frame, and the cleaning body is a non-contact power transmission mechanism consisting of a magnetic member. Discloses a technique configured to be movable up and down and left and right.

  According to this technology, there is an advantage that vibration and operation noise during the cleaning operation of the photovoltaic power generation panel can be suppressed, and complicated configurations such as wiring can be simplified. Since the brush is rotated at a constant speed to clean the photovoltaic panel, dirt attached to the photovoltaic panel can be automatically removed over the entire photovoltaic panel.

  According to this technology, it is possible to remove dirt adhered to or stuck to the surface by sweeping the surface of the photovoltaic panel while rotating, but particles such as fine sand are scattered and attached. However, it is difficult to effectively clean dust such as sand dust. In addition, if sand or the like accumulates on the photovoltaic power generation panel, the power generation efficiency decreases, and at the same time, the wheels for moving the cleaning body cannot run freely or run linearly, and the moving frame of the cleaning device becomes solar. There is also a risk of wheel removal from the photovoltaic panel, which may be an obstacle to reliable cleaning.

The solar power generation panel should be installed in a place where there are few things that block sunlight, such as sand dunes and deserts, but it is necessary to efficiently clean dust such as sand that is difficult to remove. Accordingly, there has been a demand for the development of a cleaning device for a photovoltaic power generation panel that can quickly and surely clean a panel contaminated with dust such as dust while solving the above problems.
JP 2014-22524 A

  In order to solve the above problems, the present invention is a cleaning device for cleaning a photovoltaic power generation panel, and in particular, a photovoltaic power generation panel that automatically and quickly cleans dust such as dust adhering to the solar panel.

By moving the position of the body 200 up and down, cleaning at an arbitrary height position becomes possible.

  The sandwiching member 100 is a pair of members installed at vertically symmetrical positions of the photovoltaic power generation panel 1, and as shown in FIG. 1, the cleaning body 200 is moved horizontally while sandwiching the photovoltaic power generation panel 1 from above and below. It is a member for performing. The pair of upper and lower clamping members 100 are connected via a wire 120 to be described later, and have a structure in which the photovoltaic power generation panel 1 is clamped by the tension of the wire 120. Therefore, it is desirable that the pair of upper and lower clamping members 100 be made of a strong material. . In this embodiment, stainless steel or resin material is used, but the present invention is not limited to this.

  A winding device 110 is installed on the clamping member 100. As shown in FIG. 1, the winding device 110 is installed so as to oppose each of the pair of upper and lower clamping members 100, and is configured to be a pair in the upper and lower sides. In the present embodiment, two winding devices 110 are attached to the upper and lower clamping members 100, and the winding devices 110 facing each other between the upper and lower portions form a pair.

  A wire 120 is stretched between the pair of upper and lower winding devices 110 in a state of being fitted to the winding device 110. That is, when one winding device 110 winds up the wire 120, the wire 120 mounted on the other winding device in a pair is sent out in a tensioned state. Accordingly, the pair of sandwiching members 100 are connected to each other by the wire 120 via the winding device 110, and the upper and lower sandwiching members 100 sandwich the photovoltaic power generation panel 1 by the tension of the wire 120.

The collected dust is received and accumulated, and then discarded.

  As shown in FIG. 3, the cleaning body 200 is provided with a rotary cleaning brush 210. The rotary cleaning brush 210 is a cylindrical member made of a spiral brush body and rotatably mounted on the cleaning body 200 with the vertical direction as an axis. By rotating the rotary cleaning brush 210 and brushing the surface of the photovoltaic power generation panel 1, dirt such as sand mud adhering to the panel is peeled off. In the present embodiment, one rotary cleaning brush 210 is installed at the center of the cleaning body 200. However, the rotary cleaning brush 210 is not limited to this configuration, and two or more rotary cleaning brushes are used depending on the environment where dirt is attached. 210 can be installed, and the form of the brush can be selected as appropriate.

  As shown in FIG. 3, the rotary cleaning brush 210 is provided with a drive source 220. The drive source 220 is a member that gives rotational power to the rotary cleaning brush 210. In this embodiment, a motor that is rotationally driven by electricity is used.

  The cleaning body 200 is provided with a suction collection mechanism 230. The suction collection mechanism 230 is a member for separating and collecting dust such as dust adhering to the surface of the photovoltaic power generation panel 1, and is installed as a pair on the left and right of the rotary cleaning brush 210 as shown in FIG. ing. The dust such as dust removed by the rotation of the rotary cleaning brush 210 is scattered on the photovoltaic power generation panel 1 as it is, and the photovoltaic power generation panel 1 is not necessarily cleaned cleanly as a whole. I didn't. By installing the suction collecting mechanism 230 at this position, it becomes possible to suck and collect the dust adhering to the surface of the photovoltaic power generation panel 1 and the sand dust peeled off by the rotary cleaning brush 210. It was possible to remove. Note that the compressed air for obtaining the suction force of the suction collecting mechanism 230 is supplied from the self-propelled discharge mechanism 300 as will be described later.

The air blow-off mechanism 240 is a member that blows away dust attached to the panel surface by applying wind pressure to the surface of the photovoltaic power generation panel, and is installed at both left and right ends of the cleaning body 200 as shown in FIG. The In addition, the compressed air for giving a pressure to the wind of the ventilation exclusion mechanism 240 is the structure supplied from the self-propelled discharge mechanism 300 so that it may mention later.

  By configuring the solar panel cleaning device 10 as described above, the cleaning body 200 moves in the vertical and horizontal directions while rotating the rotary cleaning brush 210 to peel off dust on the surface of the solar panel 1. Thereafter, the suction collecting mechanism 230 can perform suction removal cleaning. Moreover, when the cleaning body 200 arrives at both ends of the photovoltaic power generation panel 1, the air blow-off mechanism 240 installed on the photovoltaic power generation panel 1 end side is activated, and the separated dust is moved out of the panel. It can be blown away. Thereby, it becomes possible to clean the photovoltaic power generation panel 1 over the entire surface.

  More specifically, the horizontal moving means 130 includes a repetitive mechanism that repeats forward and backward movements. In this embodiment, as shown in FIG. 2, the horizontal moving means 130 is composed of an endless track (Catapillar (registered trademark)), and the endless track structure advances or retracts in contact with the upper and lower end surfaces and the surface of the photovoltaic power generation panel 1. By doing so, the clamping member 100 can be moved horizontally, and the cleaning body 200 can be moved horizontally. With this structure, even when dust or the like is accumulated on the photovoltaic power generation panel 1, the cleaning body 200 can be reliably moved in the horizontal direction.

  The pair of winding devices 110 is composed of a pair of motors 112a and 112b. In the present embodiment, when the cleaning body 200 is vertically moved, the motor 112a (or 112b) is rotationally driven to wind the wire 120. At this time, the other motor 112b (or 112a) is in a state where no rotational power is applied, and the wire 120 wound up in accordance with the rotational drive is sent out. Thereby, tension can be applied to the wire 120 and the cleaning body 200 can be moved vertically.

  It is desirable that the winding device 110 is provided with a stopper mechanism (not shown) so as not to rotate easily in response to an external force when no rotational power is applied. As a result, the tension of the wire 120 can be maintained, and the vertical movement of the cleaning body 200 can be stabilized. In this embodiment, two winding devices 110 are attached to the upper and lower clamping members 100, but a motor rotation control mechanism (not shown) for controlling the motors to have the same number of rotations. It is desirable to provide it. Thereby, the vertical movement of the cleaning body 200 can be further stabilized.

  As shown in FIG. 3, the suction collecting mechanism 230 has a configuration including a pair of suction nozzles 232 and a pair of squeegees 234a and 234b. The suction nozzle 232 is a nozzle for sucking dust that has been peeled off by the rotary cleaning brush 210, and is provided at a symmetrical position across the rotary cleaning brush 210. The squeegees 234a and 234b are a pair of left and right members that move by pressing dust such as dust adhering to the panel surface in contact with the photovoltaic power generation panel 1, and as shown in FIG. The solar power generation panel 1 is installed so as to be freely contacted and separated at a position between which the

  In this embodiment, as shown in FIG. 4, the squeegees 234 a and 234 b move toward the photovoltaic power generation panel 1 as the squeegee 234 a (or 234 b) on the side opposite to the traveling direction descends when the cleaning body 200 moves horizontally. The dust is pressed and moved in contact with the photovoltaic panel 1. At this time, the other squeegee 234b (or 234a) remains elevated. As a result, the squeegee 234a (or 234b) pushes and collects dust such as sand dust left by the suction nozzle 232, and the suction nozzle 232 can suck and collect again, and dust such as dust is likely to accumulate. Even in places, efficient cleaning of the solar power generation panel 1 is possible.

  The self-propelled discharge mechanism 300 is a device that tracks the cleaning body 200 and sends compressed air to the cleaning body 200 and receives dust such as dust collected by the cleaning body 200. As shown in FIG. , A plurality of wheels 320, a drive source 330, a compressor 340, an air conveyance pipe 350, a dust suction pipe 360, a storage tank 370, and a tracking sensor 380.

  The main body 310 is a main body of the self-propelled discharge mechanism 300. In this embodiment, the main body 310 is made of stainless steel or a resin material. However, since the use place is assumed to be a sand dune or a desert, a sealed structure is difficult for dust and the like to enter. It is desirable that Moreover, in order to prevent an overheating of an apparatus, using a heat insulating material etc. can also be considered. The wheel 320 is a wheel-like member for moving the main body 310, and is constituted by four wheels in this embodiment. The driving source 330 transmits driving force to the wheels 320, and an electric motor is used in this embodiment.

  The compressor 340 is a device that obtains the suction force used by the suction collection mechanism 230 of the cleaning body 200 and generates compressed air that is the compressed air used by the air blow-off mechanism 240. The air conveying pipe 350 is an elongated tubular body that delivers compressed air to the cleaning body 200. The dust suction pipe 360 is an elongated tube body that transports the dust sucked by the cleaning body 200 to the main body 310 of the self-propelled discharge mechanism 300.

  The accumulation tank 370 is a storage tank for accumulating the dust conveyed from the cleaning body 200 through the dust suction pipe 360. Further, the tracking sensor 380 is a sensor for the self-propelled discharge mechanism 300 to automatically track the cleaning body 200. The sensor controls the wheel 320 and the drive source 330 in cooperation with a tracking control mechanism (not shown) to track the cleaning body 200.

  Since the self-propelled discharge mechanism 300 has the above-described structure, the self-propelled discharge mechanism 300 can automatically move horizontally according to the horizontal movement of the cleaning body 200. It can be received via the suction pipe 360 and accumulated in the accumulation tank 370. The accumulated dust is configured to be discharged from the lower part of the accumulation tank 370. In the case of a structure that does not use the accumulation tank 370, the sucked dust is discarded as it is, but the dust sent from the cleaning body 200 has momentum due to the compressed air. There was a problem that the cleaned photovoltaic power generation panel 1 was soiled again by rolling up the dust. By using the self-propelled discharge mechanism 300 of the present embodiment, it becomes possible to continue cleaning without winding up dust such as sand and reattaching to the panel.

  The clamping member 100 may be configured to be equipped with a global positioning system (GPS) or a gyroscope. Thereby, it becomes possible to detect the horizontal and vertical position of the clamping member 100. In addition, an automatic position adjustment mechanism 140 that adjusts the traveling direction of the holding member 100 can be provided. Thereby, it becomes possible to adjust the advancing direction of the clamping member 100 using the detected horizontal / vertical position information, and even on the accumulated dust, a straight photovoltaic power generation panel while adjusting the advancing direction of the clamping member It is possible to proceed on top.

  Further, the clamping member 100 can be configured to be equipped with a laser sensor 150. The laser sensor 150 is a member that detects an obstacle in the traveling direction of the clamping member 100. Using the obstacle information detected by the laser sensor 150, the automatic position adjustment mechanism 140 can adjust the progress and direction of the holding member 100, and can stably clean the photovoltaic power generation panel 1. It becomes possible.
