Description

Solar panel cleaning device with double brush

This creation relates to the field of cleaning, especially a cleaning device that uses double brushes to perform cleaning operations on the surface of at least one solar panel.

Known solar panel structures consist of arrays of multiple solar cells. The solar panel is placed on a flat piece of ground, or in a sunny place at the top of a building. Through the Photovoltaic Effect, the solar cell converts the sun's light energy into electrical energy, which is transmitted to an appliance or a battery.

The solar panel is exposed to the sun, and there is no shelter around it. It is exposed to wind and rain, and it is easy to stick to dust, floating feathers or other dirt. Therefore, regular cleaning of the solar panel is necessary, and the conversion rate of the photovoltaic effect will not be reduced.

US Patent No. 9,400,123 discloses an array panel (Panels) that relies on a cleaning device (Cleaning Apparatus) to clean dust or remove other dirt. The cleaning unit has a Lateral Support with a set of Tubing Supports. The set of pipe supports supports a network of tubing with several nozzles (Nozzles). The lateral support rod has a bracket (Bracket) and a plate (Plates), the bracket and the plate are respectively installed with a pair of wheels (Wheels). A rotating mechanism (Swivel Mechanism) is arranged on the lateral support rod, and the rotating mechanism has a telescopic handle (Handle). Also, a brush has some soft bristles. The brushes are mounted below the lateral support bars by means of an End Brackets and a Chain Drive.

When the cleaning device is placed on the solar panel, the pipeline guides water through the nozzle to sprinkle the solar panel, and the bristles of the brush are used to clean the dust or remove other dirt. These wheels support the rolling displacement of the cleaning device on the surface of the solar panel. A user holds the handle and manipulates the cleaning device in the direction of movement of the solar panel.

However, the user acts as a support point, waving a single handle, and trying to manipulate the entire cleaning device is obviously a very laborious task.

Second, the solar panels are generally inclined. The cleaning device is placed on the solar panel, and it is quite possible to slide from a high place to a low place along the inclined angle. In particular, the wheels maintain rolling friction with the solar panels, increasing the risk of the cleaning device pulling down the user.

In order to overcome the aforementioned problems, the creator of this case proposed a "portable solar panel cleaning device", applied to Taiwan and obtained the patent right of certificate No. I650930, which is well documented.

The creator of this case is not complacent. According to the idea of patent No. I650930, the purpose of improving the cleaning device is: from a single brush to a double brush, using different rotation directions to concentrate the sewage from the outside to the inside, so as to avoid the sewage splashing out of the rack Outside the body, dirty the surrounding environment.

In order to achieve the above purpose, the cleaning device of the present invention includes: a frame body; two shafts, which are pivotally connected to the frame body and parallel to each other, and the shafts are provided with a plurality of bristles; two motors are respectively installed on the frame body; and, Two transmission rods are pivotally connected to different sides of the frame body, and the transmission rods connect the motor and the corresponding shaft together.

In a preferred embodiment, the cleaning device further includes: two control units, respectively installed on the frame body, which not only electrically connect the motors, but also operate the two shafts with different steering directions of the bristles.

In this way, the cleaning device of this creation is improved to a double-brush mechanism. With different rotation directions, the sewage is concentrated from the outside to the inside, so as to prevent the sewage from splashing out of the frame and contaminating the surrounding environment.

In order to make the purpose, features and advantages of the present creation easy to understand, one or more preferred embodiments are presented and described in detail as follows in conjunction with the accompanying drawings.

In the following description, "plurality" means two or more, unless otherwise specified.

As shown in Figures 1 and 2, the preferred embodiment of the present invention shows that a cleaning device 10 includes, but is not limited to: a frame body 11, two brushes 20, two sets of operating mechanisms 30 and a set of fluid systems 50.

The frame body 11 is a rectangular frame, and the rectangular frame is composed of two connected long rods 12 and two short rods 13 . An intermediate rod 14 secures the two short rods 13 so as to be substantially parallel to the long rods 12 in question. The frame body 11 also has two baffles 15 , and two sides of the baffles 15 are respectively combined with the long rod 12 and the middle rod 14 .

The brush 20 has a plurality of bristles 21 arranged on a shaft 22 , and two ends of the shaft 22 are respectively coupled with a bearing 23 , and the bearing 23 is mounted on the short rod 13 through a bearing seat 24 . Therefore, each short rod 13 is pivotally connected to the same end of each of the shafts 22 , so that the two brushes 20 are pivotally connected to the frame body 11 in parallel. At the same time, along the length direction of the shaft 22 , each piece of blocking piece 15 shields the partial bristles 21 .

Two sets of control mechanisms 30 are arranged on the left and right sides of the frame body 11 to control the rotation directions of the two brushes 20 . Each set of operating mechanism 30 includes, but is not limited to: a control unit 32 , a motor 33 , a transmission rod 36 , a pivot structure 40 , a driving pulley 43 , a transmission belt 44 and a driven pulley 45 . The motor 33 is electrically connected from the control unit 32 through at least one wire 34 . The control unit 32 is fixed on the two pipe bodies 31 of the frame body 11 , and the same pipe body 31 is also equipped with a motor 33 , so that the motor 33 and the control unit 32 are just on both sides of the middle rod 14 . In this embodiment, the pivot structure 40 has two bearing seats 41 , which are respectively fixed on the two short tubes 42 of the frame body 11 that are substantially parallel to each other. Each of the bearing seats 41 is sleeved with the transmission rod 36 , and the transmission rod 36 and the motor 33 (the motor shaft of the motor shaft) are connected together by an adapter 35 . The driving wheel 43 is combined with the transmission rod 36 , the driven wheel 45 is combined with the shaft 22 , and the driving belt 44 is covered with the driving wheel 43 and the driven wheel 45 to complete the control of the operating mechanism 30 The coupling relationship of the rotation of the brush 20 .

When water is injected, the water from the outside enters the joint 52 , is divided into the pipes 51 of the two long rods 12 , and sprayed by the turning sprinkler 53 to the bottom of the frame body 11 .

In FIG. 3 , the cleaning device 10 is moved to a solar panel 60 , with the bristles 21 of the two brushes 20 touching a surface 61 of the solar panel 60 , the supporting frame 11 , the operating mechanism 30 and the fluid system 50 . total weight. After power-on, one of the control units 32 determines the torque output of the motor 33 to the shaft 22, and operates one of the brushes 20 to rotate the bristles 21 in the direction of arrow 62 (or counterclockwise). Through the coupling relationship between the motor 33 and the shaft 22, the other control units 32 operate the other brushes 20 to rotate the bristles 21 in the direction of the arrow 63 (or clockwise), so the rotation directions of the two brushes 20 are different. In this way, the cleaning device 10 concentrates the sewage from the outside to the inside, and is blocked by the baffles 15 and cannot pass through the hollow frame body 11, so as to prevent the sewage from splashing out of the frame body 11 and overcome the surrounding environment. The issue of sewage contamination is relatively sanitation to protect the environment.
