technical field

The utility model relates to a light adjusting structure, in particular to a light adjusting structure for a photovoltaic power generation greenhouse, which belongs to the field of agricultural buildings.

Background technique

Photovoltaic greenhouse is a greenhouse that integrates solar photovoltaic power generation, intelligent temperature control system, and modern high-tech planting. It is a new agricultural development model that combines agricultural greenhouses with power generation. Generally, greenhouses use steel skeletons, and solar photovoltaic modules are installed on the roof. 1. The development of new photovoltaic system engineering for agricultural production in sheds is the direction of modern agricultural development. It achieves clean energy power generation through the construction of photovoltaic power projects on the roof of the shed, and is eventually incorporated into the national grid. The development of agricultural production in the shed, especially the development of economic crops, vegetables and fungi, etc., increases farmers’ income, which is a new way for farmers to get rich. Photovoltaic greenhouses not only do not occupy additional arable land, but also realize value-added in the original land, which can not only meet the lighting, irrigation and heat preservation of the entire greenhouse crops, but also provide power to the national grid to reduce pollution caused by traditional fossil energy power generation The problem is that it is an environmentally friendly new type of clean energy, and it is a new type of power facility that various countries are vying to develop. At the same time, photovoltaic greenhouses are also a development path to solve the problems of vegetables and electricity in border posts, remote areas, and poor mountainous areas.

The battery components used in photovoltaic greenhouses generally include crystalline silicon photovoltaic components, amorphous silicon photovoltaic components, and copper indium gallium selenide battery components. In order to improve the photoelectric conversion efficiency of battery components, battery devices are deposited or installed on the entire substrate, while traditional Crops and vegetables need sufficient sunlight for photosynthesis. The battery components, crops, and vegetables placed on the top of the greenhouse all need to receive sunlight. At the same time, the solar cell components and plants that need sunlight need to receive sunlight. It is a community of contradictions. There are currently two ways to solve this problem. One is to set all battery components on the top of the photovoltaic greenhouse, and fungi crops can be planted in the greenhouse to increase power generation; the other is to install transparent solar panels with the same area as the solar panels at a certain distance Light-type glass forms a photovoltaic greenhouse that can generate electricity and transmit light. However, the power generation of this photovoltaic greenhouse will be relatively reduced, that is to say, the economic benefits brought by power generation per unit area will be reduced. In addition, in order to increase the output per unit area of photovoltaic greenhouses, the distance between the greenhouses is quite small, and the front wall of the greenhouses is too low to install windows. Even if windows can be installed, in order to increase the indoor temperature in the greenhouses, the area of the windows is also quite small , This will have a negative impact on indoor ventilation, not only will affect the ventilation of the crops in the greenhouse, more importantly, it will affect the flowering and pollination effects of the crops, and will reduce the yield of the crops.

How to not only ensure the economic benefits of photoelectricity, but also ensure the photosynthesis of crops, vegetables and economic crops in the greenhouse, how to maintain the ventilation in the greenhouse, ensure the flowering and pollination of crops, and rationally allocate solar cell components and plants in the greenhouse The time to absorb sunlight is an important issue faced by photovoltaic greenhouses.

Below in conjunction with accompanying drawing, describe with regard to the specific technical scheme of the present utility model.

The technical scheme of the utility model is: a photovoltaic power generation greenhouse with adjustable light, including solar cell components 10, the roof of the greenhouse is a zigzag structure, Fig. 1 is an overall schematic diagram of the zigzag solar photovoltaic greenhouse, Fig. 2 is a solar energy Schematic diagram of the side structure of the zigzag structure of the photovoltaic greenhouse, the long side is set on the sunny side, the short side 25 is set on the shaded side, and a plurality of solar cell modules 10 are set on the sunny side, and each solar cell module 10 is provided with a frame, The frame is provided with a rotating shaft, and the rotating shaft between the upper and lower solar cell modules 10 is connected together by a crankshaft 24. The angle of the solar cell module 10 is adjustable. A sealed transparent glass 12 is connected, and a transparent glass is also provided on the side of the negative side. The rotation axis provided on the frame of the solar cell module 10 is located in the middle of the short side 25 of the frame, and the lower end of the transparent glass 11 on the negative side is provided with a The light-transmitting and reflective device 13 in which the mirror glass with an angle θ of less than 180° between the transparent glasses 11 and the light-transmitting glass 13b are alternately arranged. The driving motor 21 is directly or indirectly connected to the rotating shaft, and the driving motor 21 is connected with a rotation angle. A controller, a connecting rod 22 is arranged between the rotating shafts of the solar battery modules 10, and the rotating shafts of the upper and lower solar battery modules 10 are connected by a crankshaft 24. When the motor 21 drives the solar battery module 10 to rotate, a plurality of solar battery modules 10 simultaneous spins.

In this embodiment, the long side of the solar cell module 10 is arranged in the vertical direction, and the long side of the solar cell module 10 can also be arranged in the horizontal direction according to the structure of the battery. Likewise, the rotation axis is arranged on the short side. Although the axis of rotation can also be arranged in the longitudinal direction, the height of the sealing transparent glass 12 arranged below the solar cell module 10 will increase, which is labor-intensive and time-consuming in construction, and will also increase the manufacturing cost. At the same time, the solar cell module 10 The possibility of mutual shading will increase, increasing the possibility of damage to solar cell modules. In addition, the motor 21 drives the solar cell assembly 10 to rotate through the belt 23 , of course, it can also drive the solar cell assembly 10 to rotate in other ways.

The light-transmitting light-reflecting device 13 provided at the lower end of the transparent glass 11 on the shading side and the light-transmitting glass 13b form an angle less than 180 degrees, and a part of the sunlight irradiated from the shady side is injected into the greenhouse through the light-transmitting glass 13b. On the plants 34, the other part is reflected to the reflective layer 10a and then scattered to the plants 34 at different positions in the greenhouse. Slowly rotate the solar cell module 10 at a small angle, and use the reflective layer 10a on the back to expand the irradiation area of the plant 34, allowing the plant 34 to receive sunlight in a large area and perform photosynthesis, so as to increase the production and income of the plant 34 Effect.

The reflective layer 10a is a reflective metal film or reflective paper coated on the back of the solar cell module 10, and the angle between the transparent glass 11 on the negative side and the horizontal plane is β≤90°-(φ+23°27′), where , φ is the geographic latitude, -23°27' is the declination angle of the winter solstice,

The position of the sun is related to the season (that is, the date), time (what time of the day), and geographic latitude (the position of the observer), that is, there are three influencing factors: 1. Declination angle σ, indicating the change of the season (that is, the date); 2. Hour angle Ω, indicating the change of time; 3. Latitude φ, indicating the position of the observation point, declination δ is the angle between the sun's rays and the earth's equatorial plane.

Counting from the equatorial plane, it is positive to the north and negative to the south, which is a value indicating different seasons. It varies between ±23.5° throughout the year. Different seasons of the year have different solar declinations.

The declination angle can be checked from the declination table or calculated by the formula:

In the formula, n is the number of days, starting from January 1st.

Latitude: The latitude of a place on the Earth's surface is the angular displacement of that point from the equatorial plane to the north or south.

The latitude of the equator is zero, divided by 90° from the equator to the poles, the northern hemisphere is called north latitude, and the southern hemisphere is called south latitude (no positive or negative)

Hour angle Ω: the angle between the projection of the line OP passing through the center of the earth O and the observation point P on the equatorial plane of the earth and the projection of the line connecting the center of the sun and the earth at 12 o'clock local time on the equatorial plane.

The earth's rotation is one day, and different times have different hour angles

Ω=15t (degrees)

t—the time elapsed from the sun after noon to the observation time (positive in the afternoon, negative before noon, and 0 at noon)

Noon is 12:00 local mean solar time.

The position of the sun can be expressed in terms of altitude and azimuth. Sun altitude angle hs: The angle between the sun's rays and the ground plane. At sunrise and sunset, the solar altitude angle is zero, and at noon in the day, that is, at 12 o'clock local solar time, the solar altitude angle is the largest. Solar azimuth As: the angle at which the projected line of the sun's rays on the ground plane deviates from the south direction. Taking due south as zero, the angle in the clockwise direction is positive, indicating that the sun is in the afternoon range; the angle in the counterclockwise direction is negative, indicating that the sun is in the range of the morning.

A rough method of calculating the position of the sun:

Solar elevation angle:

Sun Azimuth:

Through the calculation of the above formula, it can be concluded that the angle between the long side and the horizontal direction of the sawtooth structure greenhouse top is φ+(5~20°), where the latitude of the location where φ is set,

An induced draft fan 14 is arranged on the front wall between the solar module and the lower sealing glass, and a ventilation valve 15 is arranged on the back wall of the intermediate layer between the solar module and the lower sealing transparent glass 12 or on the lower sealing transparent glass 12 River two-way fan 16, in this embodiment, the sealing transparent glass 12 of the lower layer is arranged between the front wall and the lower end of the transparent glass 11 on the shade side, which has a certain inclination, which is conducive to the outflow of rainwater. Therefore, in the lower layer The airtight transparent glass 12 is provided with a ventilation valve 15 and a two-way fan 16, which is conducive to the ventilation between the outside world and the middle layer, or the ventilation between the outside world and the greenhouse, or the ventilation between the middle layer and the greenhouse. The ventilation valve 15 and Two-way blower fan 16 height is higher than lower floor sealing transparent glass 12, and the upper end of ventilation valve 15 and two-way blower fan 16 is provided with rainproof cover.

Certainly, the transparent glass of part disposal direction also can be set on the lower end of the transparent glass 11 on the side of the back wall, and then the ventilation valve 15 is set on the transparent glass. By arranging induced draft fan 14 and ventilation valve 15 items of ventilation in the greenhouse, the greenhouse can be ventilated with the outside world, and the intermediate layer formed by the solar module and the sealing glass of the lower layer can be ventilated separately from the outside by using the induced draft fan 14 or the ventilation valve 15. The middle layer is ventilated with the greenhouse, and the ventilation valve 15 here is a structure in which a rotatable baffle is arranged in the air cylinder.

For the purpose of reducing the cost, the utility model arranges the ventilation valve 15 on the lower sealing transparent glass 12, and the height of the ventilation valve 15 is higher than the lower sealing transparent glass, which is beneficial to waterproofing.

When the solar module is on the same plane as the roof of the sawtooth structure greenhouse, the induced draft fan 14 can be turned on to supply air to the room and exhaust the air from the room. The rotation angle controller is provided with a remote control receiver, and the angle controller is equipped with remote control transmitter.

What Fig. 3 shows is the sunlight path that enters the greenhouse from the sunlight incident on the transparent glass 11 on the side of the shade. After the transparent glass 11 on the side of the cloud side is irradiated on the reflective glass 13a of the light-transmitting reflective device 13, the reflected light 32 is reflected on the reflective layer 10a, and the reflected light 32 forms scattered light 33 on the reflective layer 10a. The scattered light 33 is irradiated on the plant 34 in the photovoltaic greenhouse through the sealed transparent glass 12, and the plant 34 receiving the sunlight performs photosynthesis.

It should be noted that when the sun turns to the west, if you want to open the solar cell assembly on the sunny side to irradiate sunlight into the greenhouse, it will cause shading shadows between the solar cell assemblies 10. In this case, the control The system will rotate the solar cell assembly 10 by 180° to avoid blocking shadows. Therefore, in this case, the irradiation time can be adjusted as required, or the light irradiated by the transparent glass 11 on the side of the shade can be reflected into the greenhouse to irradiate sunlight. At this time, the light-reflecting layer 10a and the solar cell module 10 can be slowly rotated back and forth at a small angle, and the scattered light 33 can be irradiated on the plant 34 in the greenhouse in a large area, so as to expand the longevity area of the plant 34 in the greenhouse and promote the planting of the plant 34. Increased production and income, or more and greater harvest.

The concept of the utility model is to generate electricity and let the light shine into the greenhouse, so that multiple solar modules and economic crops or crops can receive sunlight at the same time, especially when the economic crops or crops need light, the light can be used to Adjust the controller so that both sides receive sunlight at the same time.

When adjusting the light of the photovoltaic power generation greenhouse, the light adjustment structure of the above photovoltaic power generation greenhouse and the angle adjustment controller configured in the photovoltaic power generation greenhouse are used. A cross-axis plane is formed between the rotation axes of the components 10. When multiple solar cell components and photovoltaic power generation greenhouses need to be irradiated with sunlight at the same time, a suitable acute angle is required. Set this suitable acute angle in the angle adjustment controller , under the control of the angle adjustment controller, multiple solar cell modules take the rotation axis as the axis, and rotate to the appropriate acute angle direction with the smallest rotation angle. After the angle between the two planes reaches the preset acute angle angle, the multiple solar cell modules In this angle state, as the sun rotates and rotates, a part of the sun’s incident light shines on the plurality of solar battery modules 10, and a part of the sun’s incident light shines into the photovoltaic power generation greenhouse. When the sun’s incident light is perpendicular to the plane where the rotation axis is located When on the roof, multiple solar cell assemblies 10 rotate to a symmetrical position with the sun rays and the plane of the rotation axis as the symmetrical plane, so that multiple solar cell assemblies and the photovoltaic power generation greenhouse receive sunlight at the same time, and the rotation reaches the preset time or preset time. After the angle, multiple solar cell modules are automatically reset to the original position.

When installing solar cell modules, according to the manufacturer's circuit diagram settings in solar cell modules, the direction of installation is also different. Some need to be installed vertically, while some manufacturers' solar cell modules need to be installed horizontally. Figure 4 shows the installation of solar modules vertically and A schematic diagram of an acute angle formed by a plane of sunlight crossing the axis. Fig. 5 is a schematic diagram of an acute angle formed by a horizontal solar module and a plane of sunlight crossing the axis.

In Fig. 4, 41 is the rotation axis of the solar cell module arranged vertically, 42 is the midpoint connecting line of the frame without the rotation axis of the vertical solar cell module, 62 is the sunlight plane of the rotation axis 41 of the vertically arranged solar cell module, and θ1 is the The included angle between the axial sunlight plane and a plurality of vertical solar cell components; among Fig. 5, 51 is the rotational axis that horizontally arranges solar cell components, 52 is the midpoint connection line of horizontal solar cell component frame without rotational axis, and 53 is The plane formed between the sunlight passing through the rotation axis 51 of the solar cell assembly arranged laterally and the rotation axis 51 of the solar cell assembly arranged laterally, θ2 is the angle between the plane of sunlight passing through the axis and a plurality of horizontal solar cell assemblies. When a solar cell assembly 10 and a photovoltaic power generation greenhouse need to be irradiated with sunlight at the same time, under the control of the angle controller, a plurality of solar cell assemblies rotate around a plurality of vertical solar assembly rotation axes 41 or a plurality of horizontal horizontal solar cell assemblies respectively. The shaft 51 rotates in the direction of the preset acute angle angle θ3 with the smallest rotation angle until it reaches the preset angle θ3. Under the state of the preset angle θ3, the plurality of solar battery modules 10 rotate with the rotation of the sun, so that a part of the sun Incident light 31 is irradiated on multiple solar battery modules 10, and a part of solar incident light 31 is irradiated into the photovoltaic power generation greenhouse. If it is rotated again, the front solar cell assembly will form a shadow on the surface of the back solar cell assembly, which will affect or even damage the back solar cell assembly. In order to prevent this from happening, in the technical solution of the utility model, the solar cell The assembly 10 will rotate to a symmetrical position with the sun rays and the plane where the over-rotation axis is located as a symmetric plane, so that multiple solar cell assemblies 10 and the photovoltaic power generation greenhouse receive sunlight at the same time.

Figure 6. When the sunlight plane passing the axis is perpendicular to the roof surface, the schematic diagrams before and after the rotation of multiple longitudinal solar modules with the sunlight plane passing the axis as the plane of symmetry, where 61 is the rotation of multiple solar cell modules when the solar cell modules are arranged vertically The plane where the axis 41 is located is the position of the solar cell assembly before the rotation of the symmetry plane, 62 is the plane of sunlight passing through the axis of rotation, and 63 is the position of multiple solar cell assemblies 10 after rotating with the plane of sunlight passing through the axis of symmetry , in this case, it is possible to avoid the influence of shadows on the solar cell modules behind.

After the rotation reaches the preset time or the preset angle, the plurality of solar cell assemblies 10 are automatically reset to the original position, that is, the installation position of the plurality of solar cell panels on the roof.

During the rotation process of multiple solar battery modules 10 according to the preset acute angle, the amount of sunlight received by the solar panels can be kept basically unchanged, the amount of sunlight entering the greenhouse can be kept basically unchanged, and the ratio of power generation to the amount of sunlight entering the greenhouse can be kept basically unchanged , remain in a stable state.

When it needs to be explained here, the light adjustment method of the photovoltaic power generation greenhouse is not used all the time, but the angle adjustment controller configured in the photovoltaic power generation greenhouse is turned on according to the growth period of economic crops or agricultural crops and the time required for photosynthesis. When the demand of sunlight on commercial crops or agricultural crops is relatively small, the sunlight can be directed to a plurality of solar battery modules 10 to increase the power generation efficiency.

The light-transmitting glass 13b of the device 13 irradiates the interior of the greenhouse, and at the same time, the reflective glass 13a of the light-transmitting and reflective device 13 can also be used to reflect part of the solar light to the reflective layer 10a on the back of the solar module, and then scatter into the interior of the greenhouse, and then slowly pass through a small angle. Rotating the solar cell assembly 10 back and forth can also irradiate the scattered light 33 to different positions in the greenhouse, so that a large area of the greenhouse can receive sunlight, which is beneficial to the photosynthesis of the plants 34 in the greenhouse and the growth of the plants 34 in the greenhouse. increase production and income; by setting the induced draft fan 14 on the front wall between the solar module and the lower sealing glass 12, and setting ventilation on the rear wall or the lower sealing transparent glass 12 between the solar cell module 10 and the lower sealing transparent glass 12 The valve 15 can start the induced draft fan 14 to supply air to the interior of the greenhouse when the solar module and the top of the greenhouse are on the same plane, which is beneficial to the ventilation, flowering and pollination of the plants 34 in the greenhouse, and is beneficial to the growth and fruiting of the plants 34 in the greenhouse. ; By setting the angle controller of the solar cell assembly 10 on the motor 21, and setting the remote control receiver on the angle controller, the rotation of the battery assembly on the top of the greenhouse can be remotely controlled by the remote controller, which not only helps to receive solar light, but also helps to illuminate the sun Indoors, it has the effect of photosynthesis, and by programming in the controller a reasonable allocation of photoelectric conversion power generation time and photosynthesis time program for plants in the greenhouse to receive sunlight to perform photosynthesis, both can be taken into account to achieve the best effect.
