Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic greenhouses, in particular to an ecological agricultural photovoltaic power generation greenhouse. Background Art

[0002] A photovoltaic power generation greenhouse is a greenhouse with solar thin-film panels installed on the top of an ordinary greenhouse. The solar radiation is divided into the light energy needed by plants and the light energy for solar power generation. This not only meets the needs of plant growth, but also realizes photoelectric conversion. The photovoltaic power generation greenhouse can both generate electricity and grow vegetables, a dual purpose in one greenhouse. However, the cost of building a photovoltaic power generation greenhouse is very high. A simple agricultural planting greenhouse basically cannot afford the construction of photovoltaic panels. The sightseeing photovoltaic greenhouse that combines tourism and agriculture is more prominent in cost recovery than the traditional photovoltaic agricultural greenhouse.

[0003] The dust raised by the snowfall and strong wind in winter will cover the photovoltaic modules and seriously affect the working efficiency of the photovoltaic power generation greenhouse. Even though there are dust removal equipment for cleaning photovoltaic panels on the market, most of them are installed on the outside of the greenhouse. When it snows in winter, rollers are used to drive brushes to clean the photovoltaic panels. However, in snowy weather, snowflakes accumulate when falling on the photovoltaic panels, which strengthens the adhesion between the snow and the photovoltaic panels, resulting in residual strips of snow when cleaning the snow, and then causing hot spot effects in the areas covered by the strips of snow on the photovoltaic panels, resulting in an increase in the product of the local current and voltage of the photovoltaic modules, thereby causing local temperature rise, resulting in a significant decrease in the inverter's power generation efficiency, and in severe cases, the entire photovoltaic module may be scrapped.

[0004] In view of this, the present invention proposes an ecological agricultural photovoltaic power generation greenhouse to solve the above technical problems. Summary of the invention

[0028] 2. The present invention describes an ecological agricultural photovoltaic power generation greenhouse. When the photovoltaic panel slides on the slide rail, the impact frame on the photovoltaic panel comes into contact with the spring sheet on the covering plate. The photovoltaic panel continues to slide and the impact frame bends and deforms to collide with the spring sheet, causing the covering plate to vibrate and shake off the snow on the covering plate to prevent the accumulation of snow on the top of the greenhouse, thereby increasing the load-bearing capacity of the greenhouse and eventually causing the greenhouse to collapse. At the same time, a silicone pad is installed at the connection between the covering plate and the greenhouse frame. The covering plate vibrates to squeeze the silicone pad, and the silicone pad is deformed under force, so that the covering plate has a certain movable space on the frame, which increases the vibration amplitude of the covering plate and facilitates shaking off the snow on the covering plate.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 5 As shown, the ecological agricultural photovoltaic power generation greenhouse described in the present invention includes:

[0038] A greenhouse 1, wherein the top of the greenhouse 1 is constructed by an arch frame 6 and a frame 61, wherein the arch frame 6 is constructed longitudinally and located at both ends of the greenhouse 1, and the frame 61 is constructed transversely and located on the slope of the greenhouse 1;

[0039] Photovoltaic panels 11, the photovoltaic panels 11 are located on the sun-facing side of the top of the greenhouse 1, the photovoltaic panels 11 are distributed in a chessboard pattern, and the photovoltaic panels 11 are the energy source inside the greenhouse 1;

[0040] A mounting plate 2, the mounting plate 2 is fixedly mounted on the frame 61, and the mounting plate 2 is used for heat preservation of the greenhouse 1;

[0041] The mounting plate 2 on the sunny side of the top of the greenhouse 1 is divided into a covering plate 21 and a supporting plate 22;

[0042] The cover plate 21 is located above the photovoltaic panel 11, and the photovoltaic panel 11 is located above the supporting plate 22. The vertical cross-sections of the cover plate 21 and the supporting plate 22 are in a crenel shape;

[0043] A slider is fixedly installed at the bottom of the photovoltaic panel 11, and the slider is slidably connected to the slide rail 3. The slide rail 3 is located below the support plate 22. The top of the slider is higher than the upper surface of the support plate 22. The slide rail 3 is fixedly connected to the arch frame 6.

[0044] A cleaning strip 4 is fixedly mounted on the bottom of the cover plate 21 on the side where the photovoltaic panel 11 slides out;

[0045] When working, the photovoltaic panels 11 are arranged in a chessboard pattern. On the side of the greenhouse 1 where the photovoltaic panels 11 are installed, sunlight is irradiated into the greenhouse 1 through the covering plate 21 to fully act on the photosynthesis of the plants in the greenhouse 1, while providing sufficient light in the greenhouse 1 to enhance the tourist experience in the greenhouse 1. The installation plate on the side of the greenhouse 1 that is not facing the sun does not need to be divided into the covering plate 21 and the supporting plate 22.

[0046] When it rains and snows, the external motor is started, and the photovoltaic panel 11 is connected to the motor through a traction rope. The motor drives the photovoltaic panel 11 to slide on the slide rail 3, so that the photovoltaic panel 11 enters from the top of the supporting plate 22 to the bottom of the covering plate 21, and the covering plate 21 shields the photovoltaic panel 11 to prevent rain and snow from falling on the photovoltaic panel 11 to form stains, thereby causing the generation of a hot spot effect, and ultimately causing damage to the photovoltaic panel 11; when the photovoltaic panel 11 enters under the covering plate 21, the cleaning strip 4 on the covering plate 21 cleans the dust and snow on the surface of the photovoltaic panel 11, thereby avoiding the generation of a hot spot effect; at the same time, since the cleaning strip 4 is made of sponge material, compared with a hard brush, it is less harmful to the photovoltaic panel 11 and will not cause scratches on its surface, which is also conducive to the cleaning of strip-shaped snow; at the same time, the temperature inside the greenhouse 1 in winter is generally around 18 degrees Celsius, thereby reducing the occurrence of icing on the surface of the photovoltaic panel 11, which may cause damage to the photovoltaic panel 11.

[0047] As an embodiment of the present invention, the cover plate 21 is hinged with a movable plate 41 on the side where the photovoltaic panel 11 slides out;

[0048] A fixing plate 42 is glued to the other side of the cover plate 21, and a side of the fixing plate 42 away from the cover plate 21 is fixedly connected to the supporting plate 22;

[0049] Ball bearings are rotatably mounted on both ends of the movable plate 41 away from the cover plate 21;

[0050] The movable plate 41 is not in contact with the cleaning strip 4, and the cleaning strip 4 is made of sponge material;

[0051] When working, when the photovoltaic panel 11 slides out from under the cover plate 21 through the slide rail 3, the photovoltaic panel 11 holds the movable plate 41, and then as the photovoltaic panel 11 continues to move, the movable plate 41 rotates, and then the photovoltaic panel 11 pushes the movable plate 41 open, and then the photovoltaic panel 11 slides to the top of the supporting plate 22. At this time, the movable plate 41 is located above the photovoltaic panel 11, and the movable plate 41 is hinged to the cover plate 21 through the coil spring. At this time, the coil spring is in a compressed state; when the photovoltaic panel 11 slides to the bottom of the cover plate 21 When the photovoltaic panel 11 is completely under the cover plate 21, the movable plate 41 closes the gap between the cover plate 21 and the supporting plate 22. The height of the movable plate is equal to the distance from the upper surface of the cover plate on the greenhouse to the upper surface of the supporting plate, which reduces the risk of rain and snow entering the greenhouse 1, causing the temperature inside the greenhouse 1 to drop and causing damage to the crops.

[0052] As an embodiment of the present invention, evenly distributed rollers 31 are fixedly installed at the bottom of the frame in the moving direction of the photovoltaic panel 11, and the rollers 31 are located above the supporting plate 22. The rollers 31 are in contact with the frame 61, and the rollers 31 are not in contact with the slider, and the rollers 31 roll along the frame 61;

[0053] During operation, a roller 31 is arranged at the bottom of the photovoltaic panel 11 to reduce the resistance of the photovoltaic panel 11 when sliding, so as to avoid damage to the photovoltaic components when the photovoltaic panel 11 slides; the skeleton 61 of the greenhouse 1 is in the form of a step, and the roller 31 moves on the step above the supporting plate 22 to avoid damage to the supporting plate 22 during long-term use, so as to avoid the supporting plate 22 from falling from the top of the greenhouse 1 and causing personal injury.

[0054] As an embodiment of the present invention, an arc groove is formed on a side of the cleaning strip 4 away from the movable plate 41, and the arc groove is located at an end of the cleaning strip 4 close to the photovoltaic panel 11;

[0055] During operation, when the photovoltaic panel 11 enters under the covering plate 21, the cleaning strip 4 cleans the surface of the photovoltaic panel 11, and the side of the cleaning strip close to the movable plate bends toward the side of the arc groove to clean the dust on the surface of the photovoltaic panel 11. When the photovoltaic panel 11 completely enters under the covering plate 21, the side of the cleaning strip close to the movable plate rebounds to the state when the photovoltaic panel 11 has not entered under the covering plate 21, and the dust on the cleaning strip is shaken off, so as to avoid the dust on the side of the cleaning strip close to the movable plate falling back onto the surface of the photovoltaic panel 11 when the photovoltaic panel 11 goes out from under the covering plate 21, and the dust forms an obstruction on the surface of the photovoltaic panel 11 and causes the hot spot effect.

[0056] As an embodiment of the present invention, a curved plate 32 is fixedly installed on one side of the photovoltaic panel 11 close to the movable plate 41, and the height of the curved plate 32 is consistent with the thickness of the photovoltaic panel 11;

[0057] During operation, when snow accumulates on the supporting plate 22, the photovoltaic panel 11 is extended from the covering plate 21, and the curved plate 32 on the photovoltaic panel 11 causes the snow to move in a wave-like manner as the photovoltaic panel 11 moves, and is finally pushed off the supporting plate 22, thereby preventing the photovoltaic panel 11 from being always at the bottom of the covering plate 21 due to the influence of the accumulated snow, so that the photovoltaic panel 11 can only generate electricity through the light projected from the covering plate 21, affecting the working efficiency of the photovoltaic panel 11. At the same time, the curved plate 32 can also prevent the photovoltaic panel 11 from sliding out and rubbing against the movable plate 41, causing the edge of the photovoltaic panel 11 to be worn and damaged.

[0058] As an embodiment of the present invention, the upper surface of the photovoltaic panel 11 away from the curved plate 32 is fixedly installed with impact frames 33 on both sides close to the frame 61, and the bottom of the upper and lower ends of the cover plate 21 is fixedly installed with evenly distributed springs 43;

[0059] During operation, when the photovoltaic panel 11 slides on the slide rail 3, the impact frame 33 on the photovoltaic panel 11 comes into contact with the spring piece 43 on the covering plate 21. The photovoltaic panel 11 continues to slide, and the impact frame 33 bends and deforms to collide with the spring piece 43, causing the covering plate 21 to vibrate and shake off the snow on the covering plate 21, thereby preventing the snow from accumulating on the top of the greenhouse 1, thereby increasing the load-bearing capacity of the greenhouse 1 and eventually causing the greenhouse 1 to collapse.

[0060] As an embodiment of the present invention, a silicone pad is fixedly installed at the connection between the cover plate 21 and the frame 61;

[0061] During operation, the covering plate 21 is fixedly connected to the frame 61 via a silicone pad. When the impact frame 33 collides with the spring piece 43 on the covering plate 21, the covering plate 21 squeezes the silicone pad, and the silicone pad is deformed under the force, so that the covering plate 21 has a certain movable space on the frame 61, so that the vibration amplitude of the covering plate 21 is increased, which makes it easier to shake off the snow on the covering plate 21.

[0062] As an embodiment of the present invention, a collecting trough 5 is fixedly installed on the arch frame 6 and the frame 61, the notch of the collecting trough 5 faces the outside of the greenhouse 1, and the collecting trough 5 is connected with a water supply pipe inside the greenhouse 1;

[0063] During operation, when the arc plate 32 pushes the snow on the supporting plate 22 down, the snow slides down the slope of the greenhouse 1, and the collecting trough 5 on the greenhouse 1 collects a certain amount of snow pushed down by the arc plate 32. After the snow in the collecting trough 5 melts, it is supplied to the water supply pipe inside the greenhouse 1 for irrigation or to adjust the temperature and humidity in the greenhouse 1, which is beneficial to saving water resources and avoiding waste of resources.

[0064] As an embodiment of the present invention, the surface of the collecting tank 5 is affixed with a reflective film, and the surface of the movable plate 41 is affixed with a reflective film;

[0065] During operation, when the sun shines, the collecting trough 5 and the reflective film on the movable plate 41 reflect the sunlight, so that it shines on the surface of the photovoltaic panel 11, thereby promoting the power generation of the photovoltaic panel 11 and improving the efficiency of photovoltaic power generation.

[0066] As an embodiment of the present invention, the mounting plate 2 is an acrylic plate;

[0067] When working, acrylic panels have excellent light transmittance and impact resistance that is sixteen times stronger than ordinary glass. Most importantly, they are easy to maintain and clean, and can be naturally cleaned by rainwater.
