Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments.

The inventor finds that: the existing photovoltaic module cleaning devices are large-scale electric devices and are relatively suitable for large-scale ground power stations. At present, due to the living demands and the environmental protection concept, the photovoltaic module gradually enters the family, and the existing cleaning device is neither economical nor practical for one family. Therefore, in order to not influence the power generation amount of the household photovoltaic module and enhance the operation efficiency of the power station, the inventor designs a household and economical handheld cleaning device for the photovoltaic module, which comprises: the cleaning brush comprises a handle 1, a box body 2, a cleaning brush 3, a driving motor 4, a first gear 5, a rotating shaft 6, a second gear 7, a third gear 8, a water pipe 9, a ball bearing 10, a hollow shaft 11, a fourth gear 12, an hourglass-shaped brush body 301 and bristles 302.

Example 1

As shown in fig. 1, the handle 1 is fixed on the box body 2, a transmission assembly is arranged inside the box body 2, the transmission assembly is in transmission connection with a cleaning brush 3, and the cleaning brush 3 is located outside the box body 2 and used for cleaning the photovoltaic assembly.

Because the photovoltaic module has a certain floor area, in order to ensure that the cleaning brush 3 can reach each corner of the photovoltaic module, the handle 1 is configured to be a telescopic structure, and the telescopic structure is the prior art and thus is not described in detail. Meanwhile, in order to reduce gravity, the handle 1 is made of carbon fiber, and is light in weight, high in strength and not easy to bend.

Photovoltaic module is not a smooth face, therefore at the in-process of clearance, different angles need different cleaning brushes just can guarantee better clearance. Therefore, in order to be applicable to a plurality of corners, in the present embodiment, a specific configuration of the brush 3 is shown in fig. 2, and the brush 3 includes a brush body and bristles 302. The brush body has an hourglass-shaped configuration, and the bottom surface of the brush body is planar for ease of mounting the bristles 302. The bristles 302 are thus distributed in a plurality on the bottom surface.

The two ends of the hourglass-shaped brush body 301 facilitate cleaning of corners, while also requiring the bristles 302 at the two ends to be stiffer. Thus, the distribution of the bristles 302 is as follows: the bristles 302 at both ends of the hourglass-shaped brush body 301 are densely distributed, and the bristles 302 at the center of the hourglass-shaped brush body 301 are sparsely distributed.

That is, the cleaning suitable for different corners can not be realized only by the hourglass-shaped brush hairs 302, so a transmission component is arranged in the box body 2, the transmission component is used for adjusting the steering direction of the hourglass-shaped brush body 301, and the hourglass-shaped brush body 301 can be rotated according to requirements, so that the two ends of the hourglass-shaped brush body 301 can be cleaned in a targeted and opposite-angle mode. The transmission assembly includes: the device comprises a driving motor 4 fixed in a box body 2, a first gear 5 in transmission connection with an output shaft of the driving motor 4, a rotating shaft 6 arranged in the box body 2 through a bearing, and a second gear 7 fixed at the top end of the rotating shaft 6; the first gear 5 meshes with the second gear 7. The power supply of the driving motor 4 is a 24V direct current lithium battery.

In this embodiment, the hourglass-shaped brush body 301 is detachably connected to the rotating shaft 6 through internal and external threads. In the cleaning process, when large-area cleaning is needed, the equipment is directly used; when the corners need to be cleaned, if the rotation direction of the hourglass-shaped brush body 301 is not adjusted, the most comprehensive cleaning of the corners by the brush is difficult to achieve, so that the driving motor 4 is started, and the rotating shaft 6 rotates under the driving of the driving motor 4 and the meshing of the first gear 5 and the second gear 7. The rotation of axis of rotation 6 drives hourglass type brush body 301 and realizes the switching-over, and control hourglass type brush body 301's both ends or wherein one end can cover this corner by a large scale or even comprehensively, accomplish thorough washing.

Example 2

In embodiment 1, only thorough cleaning is performed, but dry and wet combination is required as necessary during cleaning, so that a water spray assembly is provided in the housing 2 and synchronized reversing is maintained in order to be able to cooperate with the hourglass-shaped brush body 301. Therefore, the improvement is as follows: the water spraying assembly is in transmission connection with the transmission assembly, and the water spraying assembly is in transmission connection with the hourglass-shaped brush body 301.

As shown in fig. 4 to 5, the transmission assembly includes: the device comprises a driving motor 4 fixed in a box body 2, a first gear 5 in transmission connection with an output shaft of the driving motor 4, a rotating shaft 6 arranged in the box body 2 through a bearing, a second gear 7 fixed at the top end of the rotating shaft 6, and a third gear 8 tightly arranged at the bottom end of the rotating shaft 6; the first gear 5 meshes with the second gear 7.

The water spray assembly includes: the water pipe 9 is fixed in the box body 2, the ball bearing 10 is connected with the tail end of the water pipe 9 in a sealing mode (a sealing ring is arranged to ensure sealing performance), the hollow shaft 11 is connected with the ball bearing 10 in a transmission mode, the fourth gear 12 is fixed on the hollow shaft 11, and the external threads are arranged on the circumferential surface of the hollow shaft 11 located outside the box body 2; the fourth gear 12 is meshed with the third gear 8; the center of the hourglass-shaped brush body 301 is provided with a thread groove, and the hourglass-shaped brush body 301 is fixedly connected with the hollow shaft 11 through the mutual matching of the thread groove and the external thread. The interior of the hourglass-shaped brush body 301 is of a hollow structure, and a plurality of water outlets are formed at the beginning of the bottom surface of the hourglass-shaped brush body 301. The head end of the water pipe 9 extends out of the box body 2 and is connected with a water pump.

When in work: the water pump pumps water into the water pipe 9, the water in the water pipe 9 flows into the hourglass-shaped brush body 301 through the hollow shaft 11 and is sprayed out of the water outlet, and dry-wet combination is achieved.

In this embodiment, the rotation of the driving motor 4 drives the fourth gear 12 to rotate through the third gear 8, the rotation of the fourth gear 12 drives the hollow shaft 11 to rotate, and the hollow shaft 11 can drive the hourglass-shaped brush 301 fixedly connected therewith to rotate while realizing the water flow.
