Description

Automatic mobile solar panel cleaning device with steam generating module

The present invention relates to an automatic mobile solar panel cleaning apparatus having a steam generating module, and more particularly, to an automatic mobile solar panel cleaning apparatus having a steam generating module having improved solar panel cleaning efficiency.

Generally, the method of using solar energy is largely divided into a method using solar heat and a method using solar light. The method of using solar heat is to heat and generate electricity using water heated by the sun, and the method of using solar light is to generate electricity using the light of the sun and to operate various machines or apparatuses using the generated electricity. The latter is usually called photovoltaic power generation.

Unlike conventional energy sources such as fossil raw materials, photovoltaic power generation is a clean energy source without the risk of greenhouse gas emissions, noise, and environmental destruction that causes global warming, and there is no fear of exhaustion. In addition, unlike other wind or seawater, solar power generation facilities have the advantage of free installation and low maintenance costs.

The device configuration for photovoltaic power generation includes a solar cell for condensing sunlight, a photovoltaic module that is a collection of solar cells, and a solar array in which the solar cells are constantly arranged. It includes, and collectively referred to as the solar panel.

Photovoltaic power generation is to collect solar light through a solar panel to convert solar energy into electrical energy to obtain electricity. For efficient photovoltaic power generation, solar panels are installed outdoors with high light collection efficiency. Photovoltaic installations include, for example, mountainous mountains, oceans, and water-free water without surrounding interference such as reservoirs.

On the other hand, as described above, since the solar panel is installed outdoors, since the solar panel is directly exposed to natural phenomena, impurities are adsorbed to the solar panel, thereby lowering the light collecting efficiency of the solar panel. Thereby, the solar panel is cleaned through the solar panel cleaning tool (refer a nonpatent literature), and is managed so that the condensing efficiency of a solar panel may not fall.

In the solar panel cleaning operation, the worker cleans the solar panel using the cleaning tool while spraying high pressure washing water onto the solar panel. High pressure washing water injection may use a separate high pressure hose, it is also possible to use a high pressure spraying device provided with the cleaning tool.

However, the conventional solar panel cleaning tool has a problem that the cleaning workability and cleaning efficiency are not high.

First, when a strongly adsorbable impurity such as algae secretion adheres to the solar panel, a conventional cleaning tool has a problem that it is not easy to clean the secretion adsorbed on the solar panel. Even if the worker sprays the washing water at a high pressure using a conventional cleaning tool and cleans, there is a problem that algae secretions are not easily removed, such as traces of secretions remaining on the solar panel.

In particular, when the washing water is sprayed at high pressure on the solar panel may cause a problem that can damage the solar panel.

Second, since the operator must directly operate the cleaning tool, the fatigue of the worker can be increased, there is a problem that the cleaning water and impurities are scattered to the worker during the cleaning process to contaminate the worker.

Third, the prior art requires a large amount of washing water, thereby increasing the cleaning cost according to the use of water, and there is a problem in that the cleaning work must be provided with a pumping facility.

The reverse flow prevention means 230 is a component for preventing the steam generated from the steam generating module 300 to flow back to the water tank 200. As foreign matters accumulate in the steam supply pipe or the steam nozzle, which will be described later, or the high temperature steam is continuously generated, the inside of the steam generating module 300 rises together with the temperature, thereby increasing the pressure. This may occur. When the back pressure occurs, the steam discharged to the cleaning table 400 is flowed back into the steam generating module 300, the reversed steam discharged together with the existing steam in the steam generating module 300, 220 Reflowing into the water tank 200 occurs through).

The backflow preventing means 230 is configured to prevent such a steam backflow, and is installed in the discharge part 220 to prevent steam backflow of the steam generating module 300.

The inclined surface 232 is formed with a through hole 232a for allowing water to flow out of the discharge part 220. The ball member 233 serves to open and close the through hole 232a of the inclined surface 232 and is elastically supported inside the inclined surface 232 by the spring 234. Normally, the ball member 233 is in a state of always blocking the through hole 232a by the elastic force of the spring 234. The spring 234 provides an elastic force that the ball member 233 can always be supported on the inclined surface 232 as described above. While the elastic force of the spring 234 supports the ball member 233 inside the inclined surface 232, when the water of the water tank 200 is supplied to the discharge part 220 through the guide tube 231, it is caused by hydraulic pressure. It is desirable to be provided with a force that can be pushed out. In this configuration, the water in the water tank 200 is supplied to the steam generating module 300 by a pump (not shown), and since the generated water pressure can push the ball member 233, The through hole 232a may be open. Since the water pressure does not occur when the pump operation is stopped, the ball member 233 is returned to the inside of the inclined surface 232 by the elastic force of the spring 234 to close the through hole 232a.

The steam generating module 300 generates steam and is installed at one side of the water tank 200. One side of the steam generating module 300 is formed in communication with the discharge portion 220 of the water tank 200, the steam supply pipe 310 is installed on the other side of the steam generating module 300. The steam generating module 300 includes a water level sensor 320 and a heater 330.

When the cleaning device is positioned around the solar panel, the operator operates the control unit 600 to generate steam. In detail, a pump (not shown) operates to discharge water from the water tank 200 to the discharge part 220. The ball member 233 of the guide tube 231 is inclined surface 232 due to the generated water pressure. And the spring 234 is pushed together with the contraction of the spring 234 to open the through hole 232a of the inclined surface 232. The water in the water tank 200 is introduced into the steam generating module 300 through the discharge part 220 together with the opening 232a of the inclined surface 232. When the water level sensor 320 detects the proper level of the steam generating module 300, the pump operation is stopped, and as the water pressure is released by the pump stop, the ball member 233 is inclined by the elastic force of the spring 234 and is inclined. Close the through hole 232a of 232.

The heater 330 of the steam generating module 300 generates water by heating water, and the steam is discharged through the steam supply pipe 310 to the other end of the cleaning table 400 along the pipeline. The operator rotates the rotating member 420 through the control unit 600, and the rotating member 420 in close contact with the solar panel. As the solar panel is rubbed by the rotation of the rotating member 420, the impurity removing operation is performed. As the steam is additionally supplied to the solar panel in this process, the impurity removing efficiency may be maximized. As the worker continuously moves the cleaning apparatus by driving the moving means 100, the solar panel cleaning operation is performed as the above-described series of work processes are continuously performed.

On the other hand, the steam may be supplied through a separate steam discharge line rather than the cleaning table 400, it will be described by presenting as another embodiment of the present invention.
