Description

[Technical field]

[0001] The present invention relates to an apparatus for cleaning dirt adhering to the surfaces of photovoltaic panels, and more particularly to a photovoltaic panel cleaning apparatus for efficiently cleaning photovoltaic panels installed in any number of tiers. [Background technology]

[0002] Conventionally, devices for cleaning solar panels have been developed and used. Solar panels are required to be cleaned periodically because the power generation efficiency decreases when dirt adheres to the light receiving surface, and it can also cause damage and heat generation due to corrosion. In order to solve these problems, many devices for cleaning solar panels with various structures have been developed.

[0003] The size of solar panels is standardized, and the number of panels is selected according to the scale of power generation. When installing, if the scale of power generation is large, the panels are stacked vertically in several layers to ensure the area of ​​the light-receiving surface. In the case of a power generation facility where solar panels are stacked in several layers, cleaning of the light-receiving surface becomes difficult, and it becomes necessary to prepare cleaning equipment according to the number of layers.

[0004] For example, JP 2017-144413 A discloses a technology relating to a device for cleaning solar power generation panels. This technology discloses a configuration in which equipment units each having a cleaning unit for cleaning the light receiving surface of a solar power generation panel in which power generation panel units are arranged in vertical and horizontal rows, and a running unit for moving the light receiving surface in the horizontal row direction, are connected in the vertical direction by a connecting unit, and the connecting unit is provided with a sliding mechanism for sliding one equipment unit or the other equipment unit relatively in the vertical direction.

[0005] With this configuration, it is possible to reduce the number of missed cleaning steps even if the power generation panel units are of different heights; however, it is necessary to connect the units according to the height (number of installation levels) of the solar power generation panels, which requires laborious work and increases the size and cost of the equipment.

[0006] Furthermore, Patent Publication No. 2017 / 145194 discloses technology relating to a photovoltaic panel cleaning device for efficiently and automatically cleaning the entire light receiving surface of a solar panel, including a structure in which the cleaning device is installed hanging down from the upper end of the solar panel and a structure in which the cleaning device is installed so that it can move horizontally along the solar panel. In addition, a structure in which a connecting member is installed on a guide means that supports the cleaning member and the guide means are connected together, making it possible to accommodate photovoltaic panels of various heights, is disclosed.

[0007] This technology certainly makes it possible to clean the entire light receiving surface of the installed solar panels with the cleaning device, even if the solar panels are stacked vertically in several layers. However, there are problems in that the connection work is time-consuming and there is a risk that the cleaning device will fall off if there is a problem with the connection. In addition, there is an inherent risk of deterioration or damage to the device due to repeated connection and disconnection.

[0008] When the solar panels are large, if the equipment to accommodate them is also large-scale, the work itself may proceed efficiently, but the transportation, installation, and storage of the equipment require a lot of labor and cost, which places a heavy burden on the owners of the solar panels and those who perform the cleaning work.Therefore, there has been a demand for the development of a solar panel cleaning device that can be easily installed and cleaned regardless of the number of layers of solar panels, and that can efficiently clean solar panels.

BEST MODE FOR CARRYING OUT THEINVENTION

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A solar panel cleaning device according to the present invention will be described in detail below with reference to the embodiments shown in the drawings. Fig. 1 is a plan view of a solar panel cleaning device according to the present invention, Fig. 2 is a plan view showing the solar panel cleaning device installed on a solar panel and extended, and Fig. 3 is a side view showing the solar panel cleaning device installed on a solar panel.

[0017] As shown in FIG. 1, the solar panel cleaning device 1 of the present invention comprises a first frame 100, a second frame 200, and a moving means 300, and is a compact, easily transportable solar panel cleaning device that can be easily installed on panels regardless of the number of layers of power generation panels, and that enables cleaning work of the solar panel to be performed easily and reliably.

[0018] The first frame 100 is a member that allows the main body of the solar panel cleaning device 1 to move freely left and right along the solar panel P, and as shown in Figure 1, it includes a roller unit 110, a drive device 120, a first guide 130, and a first base 140.

[0019] The roller unit 110 is a member for suspending and stabilizing the solar panel cleaning device 1 body from the upper end of the solar panel P. It is also a member for enabling the suspended solar panel cleaning device 1 body to move left and right on the solar panel P. In this embodiment, as shown in Fig. 2, the roller 112 is placed on the upper end of the solar panel and the solar panel cleaning device 1 body is suspended from it. The configuration of the roller unit 110 will be described later.

[0020] The drive device 120 is a member that generates power for the solar panel cleaning device 1 main body to move over the solar panel P, and in this embodiment, as described below, the movement wheels 122 receive power and rotate over the solar panel P, thereby causing the solar panel cleaning device 1 main body to move over the solar panel P.

[0021] The first guide 130 is a rod-shaped member provided on the first frame 100, and in this embodiment, is configured as a pair of left and right rod-shaped members extending in the vertical direction as shown in Figures 1 and 2. The first guide 130 is a member for sliding the second slider 320 described below, and is configured so that the first frame 100 and the second frame 200 are connected in a freely expandable and contractible manner by the sliding.

[0022] The first base 140 is a base member for supporting the roller unit 110, the driving device 120, and the first guide 130, and in this embodiment, is configured to be provided at the upper end of the first frame 100, as shown in Figures 1 and 2. This makes it possible to stably install the first frame 100 on the photovoltaic panel P.

[0023] No. two The frame 200 is a member on which a means for cleaning the light receiving surface of the solar panel P is installed, and as shown in Figures 1 and 2, it is configured to include a cleaning means 210, a second guide 220, and a second base 230.

[0024] The cleaning means 210 is a device for cleaning the solar power generation panel P, and is a device that performs the task of removing dirt such as dust and debris adhering to the light receiving surface of the solar power generation panel P by rotating a rod-shaped brush or the like.

[0025] The second guide 220 is a rod-shaped member provided on the second frame 200, and in this embodiment, it is configured as a pair of left and right rod-shaped members extending in the vertical direction as shown in Figures 1 and 2. The second guide 220 is a member for sliding the first slider 310 described below, and is configured so that the first frame 100 and the second frame 200 are connected in a freely expandable and contractible manner by the sliding.

[0026] The second base 230 is a base member for supporting the cleaning means 210 and the second guide 220, and in this embodiment, as shown in Figures 1 and 2, is configured to be provided at the lower end of the second frame 200. This makes it possible to reliably support each means, and also makes it possible for the second frame 200 to slide vertically relative to the first frame 100, thereby changing the position (height) of the cleaning means 210 on the photovoltaic power generation panel P.

[0027] As shown in Figures 1 and 2, the solar panel cleaning device 1 is configured to include a moving means 300. The moving means 300 holds the second frame 200 so that it can freely move up and down relative to the first frame 100. With this configuration, the second frame 200 can move up and down relative to the first frame 100 to change the length of the solar panel cleaning device 1, and even if the number of installation stages (height) of the solar panel P changes, the height of the cleaning means 200 can be freely changed, making it possible to easily clean the entire solar panel P with a single device.

[0028] In this embodiment, the moving means 300 is configured to include a first slider 310, a second slider 320, a first guide 130, and a second guide 220, as shown in Figures 1 and 2. The first slider 310 is a member for holding the second guide 220 so as to be slidable, as shown in Figures 1 and 2, and is fixedly installed on the first guide 130. Also, the second slider 320 is a member for holding the first guide 130 so as to be slidable, as shown in Figures 1 and 2, and is fixedly installed on the second guide 220.

[0029] 1 and 2, the first slider 310 installed on the first guide 130 and the second slider 320 installed on the second guide 220 mutually grip the guides. In this state, when the first slider 310 slides along the second guide 220, the second slider 320 simultaneously slides along the first guide 130, and the position of the second frame 200 relative to the first frame 100 is displaced.

[0030] This makes it possible to change the length of the solar panel cleaning device 1 formed by the first frame 100 and the second frame 200, making it possible to easily install it on the solar panels P regardless of the number of stages in which the solar panels P are installed, and also makes it possible to easily change the position (height) of the cleaning means 210, thereby providing a solar panel cleaning device 1 that enables cleaning work to be performed easily and reliably.

[0031] In recent years, the number of stages of solar power generation panels installed at many solar power plants is 2 to 4. The solar power generation panel cleaning device 1 according to the present invention is a cleaning device equipped with an extension function that allows it to be installed mainly on solar power generation panels with 2 to 4 stages, but is not limited to this number of stages and can be used with solar power generation panels with any number of stages.

[0032] 1 and 3, in this embodiment, the roller unit 110 is configured to include rollers 112 and movement wheels 122. The rollers 112 are roller-shaped members that are placed on the upper end surface of the photovoltaic panel P and rotate in the longitudinal direction. In this embodiment, one or a plurality of rollers 112 are installed in the vicinity of the first base 140 of the first frame 100.

[0033] 3, in this embodiment, the driving device 120 is configured to include a moving wheel 122. The moving wheel 122 is a member for transmitting power for moving the main body of the solar panel cleaning device 1 to the solar panel P, and rotates the light receiving surface of the solar panel P by receiving the driving force. In this embodiment, one or a plurality of moving wheels 122 are installed.

[0034] With this configuration, it is possible to stably install the solar panel cleaning device 1 on the solar panel P, and it is possible to perform the cleaning process while automatically moving laterally by receiving power, making it possible to perform efficient cleaning work on the solar panel P.

[0035] 3, in this embodiment, the cleaning means 210 is configured to include one or more rod-shaped brushes 212 that rotate by receiving a driving force. The rod-shaped brush 212 is in the shape of a rod with a circular cross section, and is configured to clean the light receiving surface of the solar power generation panel P by rotating. This configuration makes it possible to reliably clean the light receiving surface of the solar power generation panel P without damaging it. Note that the cleaning means 210 is not limited to a rod-shaped brush, and may also be a circular rotating brush or blade.

[0036] In conventional photovoltaic panel cleaning devices, a method for cleaning photovoltaic panels installed in multiple tiers is often adopted in which guide members installed in the cleaning device are connected to each other at multiple points, thereby changing the height of the cleaning device and thoroughly cleaning the entire photovoltaic panel. However, this structure has problems in that the number of connecting members is large, making it complex, heavy, and increasing the amount of work. The increased weight makes it difficult to transport the cleaning device and difficult to install the cleaning device on the photovoltaic panels.

[0037] The present invention uses an extendable solar panel cleaning device, which makes the device compact and lightweight despite the complex operation, making it easy to transport and install. [Brief description of the drawings]
