Technical Field

[0001] The invention relates to the technical field of photovoltaic sand control, and in particular to a comprehensive photovoltaic sand fixation device and a sand fixation method. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of operation: independent operation and grid-connected operation. At present, photovoltaic power generation projects built in desert areas have the problem of wind and sand erosion.

[0003] Photovoltaic panels shield direct sunlight, effectively reducing the evaporation of surface water and effectively reducing wind speed. This can greatly improve the living environment of plants. Photovoltaic brackets support photovoltaic power generation devices, and photovoltaic support piles support photovoltaic brackets. Photovoltaic support piles are fixed on the ground. Under the action of strong winds, the sand layer at the pile foundation of photovoltaic support piles is easily blown away, making the pile foundation exposed and eroded by wind and sand, destroying the bearing capacity of photovoltaic support piles, and then affecting the stability of photovoltaic support piles, posing safety hazards, and the dust raised in strong winds has a greater impact on power generation.

[0004] Therefore, we made improvements to this and proposed a comprehensive photovoltaic sand fixation device and sand fixation method. Summary of the invention

[0007] As a further solution of the present invention, the fixing seat includes a support plate, a slide groove is opened in the middle of the support plate, a plurality of connecting frames fixedly connected to the protective net are installed on the inner side of the support plate, and the bottom of the support plate is fixedly connected with gripping nails.

[0008] As a further solution of the present invention, the photovoltaic power generation mechanism includes a photovoltaic panel, one end of the photovoltaic panel is fixedly installed with a fixing column, the bottom end of the fixing column is fixedly installed on a fixing seat, the upper end of the photovoltaic panel is fixedly connected with a movable connecting column, the bottom end of the movable connecting column is fixedly installed with a slider, one end of the slider is slidably sleeved inside the slide groove, and the other end of the slider is sleeved on the outside of the thread of the second threaded rod.

[0009] As a further solution of the present invention, the sand accumulation mechanism includes a support frame, connecting sleeves are installed on both sides of the support frame, the connecting sleeves are threadedly connected to the first threaded rod, and a sand box is fixedly connected to the upper end of the support frame. The sand box is a superimposed structure of two square cones that are wider on the top and narrower on the bottom, and windows are opened on the four sides of the sand box, and a gauze is hinged on the inner side of the window, and the size of the gauze is larger than the window.

[0010] As a further solution of the present invention, the protective net includes a grating, a plurality of connecting buckles are installed on both sides of the grating, the connecting buckles are fixedly connected to the connecting frame, and a floor net is connected in the middle of the grating.

[0011] As a further solution of the present invention, the water accumulation net includes a connecting net, one end of the connecting net is connected to a first connecting rod, both ends of the first connecting rod are fixedly connected to short frames, the other end of the connecting net is fixedly connected to a second connecting rod, both ends of the second connecting rod are fixedly connected to long frames, and the bottom ends of the short frame and the long frame are fixedly installed on a fixed seat.

[0012] As a further solution of the present invention, the water collection net is folded in a W shape and continuously installed on a fixing seat, and the length of a single side of the water collection net is consistent with the length of the photovoltaic power generation mechanism.

[0013] As a further solution of the present invention, the fixing column is installed at the midpoint of the fixing seat, and the sliding block reciprocates between the two ends of the fixing seat.

[0014] A sand fixation method, using the above-mentioned comprehensive photovoltaic sand fixation device, comprises the following steps:

[0015] S1. Install the fixed seat in the desert area, connect the protective net between the two fixed seats, cover the sand layer on the protective net to increase the stability of the bottom of the fixed seat and the protective net, and support and install a photovoltaic power generation mechanism on the upper end of the fixed seat, use the photovoltaic power generation mechanism to generate photovoltaic power, and use the photovoltaic power generation mechanism to shade the sand. The photovoltaic component panels shield the direct sunlight, effectively reduce the evaporation of surface water and effectively reduce the wind speed, improve the living environment of plants, and manage the desert. At the same time, one end of the photovoltaic panel is fixed by a fixed column, and the slider at the bottom of the movable connecting column is connected to the second threaded rod. The first motor drives the second threaded rod to rotate, and the second threaded rod drives the slider to slide along the fixing seat every morning and evening, so that the photovoltaic panel flips along the fixing column in the morning and evening. After flipping, the front of the photovoltaic panel is tilted downward to contact the water accumulation net. The water accumulation net condenses water molecules in the air at night and attaches them to the photovoltaic panel and the water accumulation net, and flows out along the inclined surface of the photovoltaic panel to clean the photovoltaic surface of the photovoltaic panel, so as to prevent the dust raised by the wind and sand during the day from affecting the power generation of the photovoltaic panel. At the same time, the water condensed by the photovoltaic power generation mechanism and the water accumulation net replenishes the growth of surface vegetation, which is beneficial to the recovery of vegetation in desert areas.

[0016] S2. At the same time, due to the high wind speed in the desert area, the sand layer accumulated on the protective net is easily moved away by the wind, causing the photovoltaic support piles of the fixed seat to be exposed more and not fixed firmly. At this time, a sand accumulation mechanism is arranged above the protective net, and the sand accumulation mechanism is connected to the first threaded rod through a connecting sleeve. The first threaded rod is driven by the first motor to rotate and drive the sand accumulation mechanism to reciprocate above the protective net. A sand box is fixedly installed on the upper end of the support frame. A window is opened on the side of the sand box, and a one-way opening gauze is installed in the window to intercept the wind and sand. The wind and sand are separated on the gauze and enter the sand box through the gauze for storage. With the reciprocating movement of the sand accumulation mechanism, the sand is evenly laid on the protective net, increasing the thickness of the sand layer on the protective net and ensuring the stability of the fixed seat and the protective net.

[0017] S3. The water accumulation network is W-shaped and connected below multiple photovoltaic power generation mechanisms. While blocking and protecting against wind and sand, it uses the temperature difference and changes in relative humidity at night to condense moisture in the air into water droplets that adhere to the water accumulation network, thereby capturing moisture in the air in desert areas. The moisture in the air is condensed into water droplets and collected, and then falls to the growth area of ​​surface vegetation at the lowest point of the water accumulation network to replenish water for the surface vegetation.

[0018] The comprehensive photovoltaic sand fixation device and sand fixation method provided by the present invention have the following beneficial effects:

[0019] 1. A water accumulation net is installed on the upper end of the fixed seat, and the photovoltaic power generation mechanism is installed close to the water accumulation net, so that the photovoltaic panel can be flipped in the morning and evening under the connection of the fixed column and the movable connecting column. The first motor drives the second threaded rod to rotate, and the second threaded rod drives the slider to slide along the fixed seat, and the photovoltaic panel flips along the fixed column. After flipping, the front of the photovoltaic panel is inclined downward and contacts the water accumulation net. The water accumulation net condenses water molecules in the air at night and attaches them to the photovoltaic panel and the water accumulation net, and flows out along the inclined surface of the photovoltaic panel to clean the photovoltaic surface of the photovoltaic panel, so as to avoid the dust raised by the wind and sand during the day affecting the power generation of the photovoltaic panel. At the same time, the water condensed from the photovoltaic power generation mechanism and the water accumulation net replenishes the growth of surface vegetation, which is beneficial to the recovery of vegetation in desert areas.

[0020] 2. A sand accumulation mechanism is arranged above the protective net, which is connected to the first threaded rod through a connecting sleeve. The first threaded rod is driven to rotate by a first motor to drive the sand accumulation mechanism to reciprocate above the protective net. A window is opened on the side of the sand box and a one-way opening gauze is installed to intercept the wind and sand inside the sand box for storage. With the reciprocating movement of the sand accumulation mechanism, the sand is evenly spread on the protective net, increasing the thickness of the sand layer on the protective net and ensuring the stability of the fixed seat and the protective net. The problem that the wind speed in the desert is high and the sand layer is easily moved away by the wind, resulting in a large amount of exposed photovoltaic support piles of the fixed seat and loose fixation, is solved.

[0021] 3. Photovoltaic power generation is carried out through photovoltaic power generation mechanisms, and photovoltaic power generation mechanisms are used to shade the sand at the same time. Photovoltaic module panels block direct sunlight and effectively reduce the evaporation of surface water and effectively reduce wind speed, improve the living environment of plants, and manage the desert. The water accumulation network is W-shaped and connected under multiple photovoltaic power generation mechanisms. While blocking and protecting against wind and sand, at night, the temperature difference and relative humidity changes are used to condense the moisture in the air into water droplets attached to the water accumulation network, and the moisture in the air in the desert area is captured. The moisture in the air is condensed into water droplets and collected, and dropped at the lowest point of the water accumulation network on the growth of surface vegetation to replenish water for the surface vegetation.

[0035] The sand accumulation mechanism 7 includes a support frame 71, and connecting sleeves 72 are installed on both sides of the support frame 71. The connecting sleeves 72 are threadedly connected to the first threaded rod 2. A sand box 73 is fixedly connected to the upper end of the support frame 71. The sand box 73 is a superimposed structure of two square cones that are wide at the top and narrow at the bottom, and windows 74 are opened on the four sides of the sand box 73. A gauze 75 is hinged on the inner side of the window 74. The size of the gauze 75 is larger than the window 74. The sand box 73 filters the wind and sand, so that the sand is sifted out through the gauze 75 and stored in the sand box 73. A cover plate 76 is installed on the upper end of the sand box 73.
