DETAILED DESCRIPTION

[0030] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0031] like Figure 1 As shown, a photovoltaic water collection system with automatic dust removal function includes a photovoltaic water collection device 1, a sedimentation tank 2, a water storage tank 3, a dust cover identification device 4, a spray device 5, a soil moisture monitoring device 6 and a big data control center 7;

[0032] The photovoltaic water collection device 1 is provided with a water collection pipe 8, which is connected to the sedimentation tank 2 to send the rainwater collected by the photovoltaic water collection device 1 to the sedimentation tank 2. The sedimentation tank 2 is connected to the reservoir 3, and the clean water after precipitation in the sedimentation tank 2 is sent to the reservoir 3.

The big data control center 7 correspondingly controls the cleaning pump 11 to extract clean water from the water reservoir 3 to the spray system to clean and remove dust from the photovoltaic panel.

[0034] like Figure 2 and Figure 3 As shown, the photovoltaic water collection device 1 includes a water collection frame 101, on which a support member 102 is provided, through which a photovoltaic mounting plate 103 is correspondingly provided, and on which a solar photovoltaic panel 104 is correspondingly installed; a water collection gap 109 is provided between the solar photovoltaic panel 104 and the left frame wall 105, the right frame wall 106, the lower frame wall 107 and the frame bottom plate 108 of the water collection frame 101; and the solar photovoltaic panel 104 is correspondingly provided in close contact with the upper frame wall 110 of the water collection frame 101;

[0035] The dust cover identification device 4 is correspondingly embedded in the upper frame wall 110, and the identification direction is horizontally aligned with the inner solar photovoltaic panel 104;

[0036] The spray device 5 includes a spray head 501 and a spray pipe 502. The spray head 501 is also embedded in the upper frame wall 110, and the spray direction is aligned with the inner solar photovoltaic panel 104; the spray pipe 502 is correspondingly connected to the spray head 501, and the spray pipe 502 is correspondingly embedded in the upper frame wall 110 and the frame bottom plate 108, and is correspondingly led out from the lower end of the frame bottom plate 108 and connected to the water reservoir 3 through the cleaning pump 11.

[0037] The water collecting pipe 8 is correspondingly arranged at the lower end of the water collecting frame 101 , and the water collecting pipe 8 is correspondingly connected to the sedimentation tank 2 ; a filter 12 is also correspondingly installed between the sedimentation tank 2 and the water storage tank 3 .

[0038] like Figure 4 and Figure 5 As shown, a wind mechanism 13 is correspondingly installed at the lower frame wall 107 of the water collecting frame 101, and air vents 14 are correspondingly embedded in the left frame wall 105, the right frame wall 106 and the lower frame wall 107 of the water collecting frame 101; and wind channels 15 are also embedded in the left frame wall 105, the right frame wall 106 and the lower frame wall 107, and the wind mechanism 13 is correspondingly connected to the air vents 14 on the three frame walls through the wind channels 15.

[0039] The setting height of the air outlet 14 is higher than the height of the solar photovoltaic panel 104 , and the blowing direction of the air outlet 14 is downwardly directed toward the solar photovoltaic panel 104 .

[0040] The wind mechanism 13 is correspondingly installed in the housing 16 , and an air inlet filter 17 is correspondingly arranged in the housing 16 .

[0041] The specific working process of the technical solution of the present invention is as follows: first, the present invention collects rainwater through a photovoltaic water collection device, and the collected rainwater passes downward through a water collection pipe into a sedimentation tank below, and the water body is precipitated in the sedimentation tank to obtain clean water above, and the clean water obtained in the sedimentation tank is sent to a reservoir through a filter, a water pump and other equipment. The rainwater in the reservoir is clear water; then the rainwater in the reservoir is sent to a designated planting area through an irrigation pump for water irrigation.

[0042] In the specific process of water irrigation, the present invention also provides a soil moisture monitoring device, which can be buried in the planting area to monitor the soil condition. When the soil is short of water, it will transmit a signal to the big data control center accordingly, and the big data control center will control the irrigation pump to start irrigating the soil.

[0043] In addition, the present invention also provides a spray device for cleaning the photovoltaic water collection device. The cleaning water of the spray device also comes from the water in the water reservoir, and a dust cover identification device needs to be installed on the photovoltaic water collection device to identify whether there is dust on the photovoltaic water collection device. The dust cover identification device already exists in the prior art, and can be specifically identified by taking images with a camera device, or by an infrared device.

[0044] When dust is detected on the photovoltaic water collection device, a signal can be transmitted to the big data control center, which controls the cleaning pump to introduce the water in the reservoir into the spray system to remove dust from the photovoltaic water collection device to ensure the efficiency of photovoltaic power generation; and the water used for cleaning can be circulated into the sedimentation tank and the reservoir accordingly.

[0045] In addition, the present invention specifically sets up the structural form of the photovoltaic water collecting device. The photovoltaic water collecting device of the present invention specifically includes a water collecting frame, and a supporting member is set on the frame bottom plate of the water collecting frame to support the installation of the photovoltaic mounting board, and then the solar photovoltaic panel is correspondingly installed on the photovoltaic mounting board. At the same time, a water collecting gap is set between the left frame wall, the right frame wall and the lower frame wall of the water collecting frame. When it rains, rainwater flows into the water collecting frame from the water collecting gap, and flows into the sedimentation box through the water collecting pipe below.

[0046] The upper frame wall of the water collection frame has a different structure from the other frame walls. The upper frame wall is located close to the photovoltaic mounting panel and the solar photovoltaic panel. The purpose of this setting is to install a spray device and a dust cover identification device in the upper frame wall.

[0047] First of all, the dust cover identification device is set up, which is specifically embedded in the inside of the upper frame wall, and is set in a special direction to the solar photovoltaic panel, and the spray head of the spray device is also embedded in the upper frame wall, and is correspondingly set on the upper side of the dust cover identification device. The direction of the spray head is also aimed at the solar photovoltaic panel below, and the corresponding spray pipe is correspondingly embedded in the upper frame wall and the bottom plate of the frame, and then goes down into the water reservoir. When the solar photovoltaic panel needs to be dusted and cleaned, the cleaning pump introduces water into the spray head through the spray pipe to spray and clean the solar photovoltaic panel, and the water flows down along the solar photovoltaic panel to clear the dust on it.

[0048] However, the above technical solution of only cleaning by water spraying may not be able to effectively remove dust on the solar photovoltaic panels, because some dust has strong adhesion and causes adhesion, etc., and may not be cleaned up by the natural flow of water.

[0049] Therefore, in addition to the spray device, the device also has a wind mechanism to assist in dust cleaning. Figure 4 and Figure 5 As shown, first, the wind mechanism is set on the lower frame wall of the water collecting frame, and at the same time, air outlets are set on the left frame wall, the right frame wall and the lower frame wall, and then wind channels are set on the three frame walls. The wind mechanism can be used to introduce external air into the wind channels in the three frame walls, and finally the wind airflow is ejected from the air outlet; the position of the air outlet corresponds to the position of the solar photovoltaic panel, and the airflows in three directions are all aimed at the solar photovoltaic panel, so the solar photovoltaic panel can be dusted by wind, and some stubborn dust attached to the panel body can be removed by strong wind, and at the same time, the water left by the spraying device can effectively increase the dust removal effect, and the overall structural setting is very reasonable.

[0050] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
