The present application claims priority to application number GB2111682.7, filed on Aug. 13, 2021, the disclosure of which is hereby incorporated in its entirety at least by reference.
The present invention relates generally cleaning equipment but more particularly to a cleaning system for a circular panel.
The use of solar panels is becoming ubiquitous. A big problem is how to keep them clean without the need for a lot of manpower. There are also other surfaces that need to be kept clean, such as reflective surfaces whether bright white or mirror surfaces.
There are many systems that have been invented for automatically cleaning glass or mirrors and some of those systems can also be used for cleaning the surface of solar water heaters or photovoltaic panels.
For example British patent GB222225 describes a car mirror with a windscreen wiper, comprising a shell, a silvered mirror, a windscreen wiping rod which is adhered with the mirror, and a rotary shaft which penetrates through a centre hole of the mirror. The inner chamber end of the rotary shaft in the shell is connected with fan blades, the back surface of the shell is provided with an air inlet hole, and the lower surface of the shell is provided with an air outlet hole. The shell is further provided with an air inlet hole plug. High-speed airflow enters the air inlet hole arranged on the back surface of the shell while car runs in rainy days so as to blow the fan blades in the inner chamber of the shell, and then the windscreen wiping rod is driven to rotate through the rotary shaft to wipe the irregular raindrops on the mirror, so that the driving safety can be ensured, and motors and batteries are not needed. After the air inlet hole is plugged though the plug, the windscreen wiping rod stops.

Referring now to any of the accompanying
As best seen in
In one embodiment, the pivot member 18 is further comprised of a base 30 which is mechanically fastened to the circular panel 12, a disc member 32, and an axis stub 34 which is pivotally connected to the base 30 by passing through holes 36 made through both the disc member 32 and the base 30.
In some embodiments, the pivot member 18 has a wind vane 26 on its top portion which is connected to a charger for generating the electricity needed to operate the system 10 such as rotating the blades 15, 17 and actuating all other electrically powered equipment such as pumps for the liquids and computer board, among others. Advantageously, in this manner, the system 10 does not take up the energy from the solar panels. Any excess energy produced can be stored in a battery for use on other systems if needed.
The second blade 17, which sits on top of the first blade 15, is used mostly for wiping excess snow and ejecting thawing fluid. This will be described in further details below. In one embodiment, the second blade 17 is comprised of a brush 22′ extending upwardly therefrom. In one embodiment, the brush 22′ is transparent such that it does not project a shadow on the circular panel 12. The blade 17 also contains other holes 39 for the injection of cleaning liquid to rinse and clean the brush 22′.
Additionally best seen in
Advantageously, the two blades 15, 17 can rotate independently. For example, when there is a lot of snow, the second blade 17 moves first to clear the snow and sprinkle thawing liquid, and then the first blade 15 starts moving. Further, the blades 15, 17 can rotate clockwise or counterclockwise. This is advantageous since the sprinklers are located on both sides of the blades 15, 17 (only one side visible in the drawings) and can contain different liquids. So, for example, if there is a need for a thawing liquid, the blade 15, 17 would turn in the direction the liquid is being sprinkled. When there is ice or frost on the panel which blocks the movement of the first blade 15, the second blade 17 is activated to inject the thawing liquid all along the panel in order to thaw the ice and release the first blade 15, and once the first blade 15 is released, it can be activated to clean the remaining ice on the panel.
Different configurations of mirrors can benefit from the blade 10 as seen in
As best seen in
Another advantage of the sprinklers is that they can act as means for cooling the solar panels and prevent thermal shock that could cause the glass to crack, while also keep the panels from getting too hot as extreme heat reduces the photovoltaic efficiency.
