Description

A MOVEABLE DOCKING SYSTEM FOR PV SOLAR POWER PLANT

FIELD OF THE INVENTION

The present invention relates to a docking system for solar power plant, more specifically the present invention relates to a movable docking system for cleaning solar plant with a robot.

BACKGROUND

In the present age pollution, climate change, global warming are the major issues; in order to overcome these problem world has started tending towards renewable energy resources. Solar energy is one of the prominent renewable energy. Global installed capacity for solar- powered electricity has seen an exponential growth. Solar energy barely contributes to electricity used globally. In order to increase global percentage of solar energy its efficiency has to be increased. The technologies for utilization of solar energy vary as how they capture and utilize the solar energy. The most common method for utilization of solar energy is by using the photovoltaic panels. Efficiency of photovoltaic panel depends on many factors like amount of sun light, place, dust, bird's wastes etc. so it requires cleaning. On photovoltaic panel layer of dust is formed which decreases its efficiency. This dust has to be cleaned through two techniques, either by manual cleaning or by mechanical cleaning. As solar power plant is in large area so manual cleaning of photovoltaic panel takes more time, labor and cost. To overcome this problem different mechanical system has been developed so far, robotic cleaning is one among them. Different robotic cleaning system has been developed but transfer of robot from one array to another is still a problem.

CN202105809 (U) discloses a The utility model provides a solar panel cleaning device, which comprises a movable device and a cleaning device arranged on the movable device. The cleaning device comprises a support unit and a cleaning unit arranged on the support unit, and the cleaning unit is used for cleaning a solar panel. The cleaning device has high cleaning efficiency and good cleaning effects, the maximum power generation efficiency of the solar panel can be achieved after cleaning, and the cleaning device is particularly suitable for cleaning of the solar panel of a photovoltaic power station.

US9352941 (B2) discloses gantry crane vehicle for performing one or more tasks in a photovoltaic array and method thereof. The gantry crane vehicle includes one or more base plates, and one or more tracks above the one or more base plates. Additionally, the vehicle includes one or more gantry assemblies configured to slide along the one or more tracks, and one or more first support trusses configured to support the one or more tracks above the one or more base plates. Moreover, the vehicle includes one or more second support trusses connected to at least some of the one or more first support trusses, and one or more storage cabinets located on the one or more base plates. The one or more storage cabinets include one or more top surfaces and one or more side surfaces, and the one or more top surfaces are located below the one or more tracks.

US8046101 (B2) discloses Provided is a cleaning robot system and a method of controlling the same for economically cleaning, with high workability, plate-shaped members, such as solar cell panels and reflecting mirrors used in photovoltaic power generation and solar thermal power generation systems. A cleaning robot system for cleaning planar or curved plate-shaped members that are panels for photovoltaic power generation or reflecting mirrors for solar thermal power generation includes: a large number of cleaning robots each having a function to travel on each of the plate-shaped members which are to be cleaned and a function to clean the plate-shaped members; and an arranging robot having a conveying function to move any of the cleaning robots from a first one of the plate-shaped members to a second one of the plate-shaped members. Each of the cleaning robots has a suction mechanism for performing cleaning while attaching onto one of the plate-shaped members, and the large number of cleaning robots and a smaller number of the arranging robots than that of the cleaning robots cooperate together to clean the plate-shaped members placed in a photovoltaic power generation or solar thermal power generation plant. As photovoltaic panels are placed on height so robot has to be docked over them for effective cleaning and robot has to be transferred from one row of photovoltaic panel to other. The drawbacks of existing systems are that they do not transfer robot from one place to other in uneven surface and are not effective for cleaning purposes. The existing systems are very complex in nature and difficult to handle. Present invention overcomes the deficiencies in the prior art by transferring robot from one array to other hence the present invention is needed.
