The photovoltaic module can directly convert sunlight energy into electric energy, and cannot cause environmental pollution in the power generation process, so that the photovoltaic module is an environment-friendly energy production device. In order to improve the yield of animal husbandry and planting industry and further improve economic benefits, a photovoltaic solar power generation device is erected by utilizing a cultivation shed and a greenhouse for planting. The cultivation shed or the planting shed can be reasonably utilized, and the use cost of the cultivation shed or the planting shed can be reduced. The solar photovoltaic power generation has great development potential in the aspects of cleanness and environmental protection, although the manufacturing technology of photovoltaic products is relatively mature, irradiance in most areas in one year is not more than 600 watts per square meter on average and is only about 60% of standard test conditions of 1000 watts per square meter, so that most of the time of the photovoltaic module operates under low irradiance, namely the light quantity of the photovoltaic module is less in most of the time, namely the lower power generation quantity of the photovoltaic module is indicated, the lower power generation quantity of the photovoltaic module leads to the improvement of the final photovoltaic power generation cost, and the adaptability adjustment and improvement of the module functions and matched accessories are required aiming at the characteristics of photovoltaic power generation, so that the light utilization efficiency and the power generation quantity are improved; the double-sided photovoltaic panel assembly can be adopted to improve the light utilization efficiency, but sunlight irradiates only one side of the double-sided photovoltaic panel assembly, and the generated energy cannot be increased; if sunlight is reflected to the other side of the double-sided photovoltaic panel assembly by using the reflecting mirror, the generated energy can be increased, but light pollution can be caused to the air, aircraft flight and the like are possibly disturbed, so that the photovoltaic panel assembly, the reflecting device and other accessories are required to be improved, and the effects of enabling the double sides of the double-sided photovoltaic panel to enter light and not causing light pollution to the environment are achieved; in addition, the design and installation of the double-sided photovoltaic panel assembly device are unsuitable, sunlight required by the growth of crops or livestock in the greenhouse can be shielded, the crop yield is reduced, the growth of the livestock is blocked, even the livestock is pathogenic, and therefore the photovoltaic panel assembly and the reflecting device are required to be correspondingly improved, so that the growth of the crops or the livestock in the greenhouse is not influenced. The technical scheme aims at that the light quantity of the double-sided photovoltaic panel assembly is small, and the generating capacity efficiency is low; the reflector is used for increasing the light entering quantity of the double-sided photovoltaic panel assembly, and the light pollution in the air can be caused; or the defects that the design and the installation of the device are not suitable for influencing the growth of crops and domestic animals are studied, and a technical scheme of the double-sided photovoltaic power generation conversion device which is erected between sheds and used for overcoming the defects is designed.

the problems that in the prior art, the light quantity of a photovoltaic module is small, the generated energy is low and the power generation cost is increased are solved; meanwhile, the problem that the reflector in the prior art possibly causes air light pollution is solved; the problem that the photovoltaic assembly device in the prior art can affect the growth of crops and livestock in the greenhouse is also solved.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

a double-sided photovoltaic power generation conversion device used for a shed frame comprises double-sided photovoltaic panel assemblies vertically installed between two adjacent greenhouses, a herringbone reflecting plate hinged to each other at the tops of the greenhouses, a traction device for traction connection of the herringbone reflecting plate to change an included angle of the herringbone reflecting plate, and a control system for controlling the operation of the traction device.

The system for increasing the generated energy by utilizing the double-sided photovoltaic system and the reflection curtain between the greenhouses further comprises the following auxiliary technical scheme:

the photovoltaic panel assembly is fixed between two adjacent greenhouses through the support posts, so that the occupied area is reduced, the installation space is saved, the installation cost is reduced, and the surface of the assembly is not easy to accumulate dust, rain and snow and has strong self-cleaning capability. The support column for installing the photovoltaic module is not associated with the greenhouse, so that the influence on the stability of the greenhouse due to different loads such as dead weight, wind, snow, construction, overhaul and the like of a product is effectively avoided or reduced.

In the device, the double-sided photovoltaic panel assembly is vertically installed in the north-south direction, so that the light quantity of the photovoltaic panel is maximum.

In the device, the herringbone reflecting plate is movably connected with the top of the greenhouse in a hoisting mode. The herringbone reflecting plate is a plane reflecting plate or a reflecting plate covered with a flexible reflecting film, the included angle adjusting range is 0-180 degrees, and the surface of the reflecting plate is formed by paving high-reflecting materials, such as silver.

The traction device is a traction rope for traction of the herringbone reflecting plate to change the included angle.

The control system controls the opening angle of the herringbone reflecting plate according to the power generation conversion requirement, the sunlight irradiation angle and the light requirement of plants in the shed. The herringbone reflecting plate reflects sunlight irradiated on the herringbone reflecting plate onto the double-sided photovoltaic plate outside the greenhouse, so that the light receiving intensity and uniformity of the back surface of the photovoltaic plate are guaranteed, the photovoltaic module receives direct irradiation of sunlight and also receives reflected light from the reflecting plates in the greenhouse on two sides, the light utilization of the double-sided photovoltaic module is improved, and the photoelectric conversion efficiency is improved. Compared with the common photovoltaic module, the generating capacity of the photovoltaic module is increased by about 50 percent due to the fact that the additional reflected light is received.

The herringbone reflecting plate almost totally reflects the received sunlight on the photovoltaic plate and crops, the sunlight is not reflected into the air, the air is not polluted by light, and the interference to the flight of an airplane is avoided.

Because the herringbone reflecting plates utilize and shield direct sunlight in the greenhouse, the greenhouse needs to shade the direct sunlight so as to reduce evaporation of ground water, which is particularly important for plant growth in arid areas with large sunlight radiation and small rainfall; moreover, the herringbone reflecting plate almost does not shade scattered light required by the growth of crops, and does not influence the growth of the crops in the greenhouse.

If the power system generates electricity and remains or plants in the greenhouse need sunlight, the herringbone reflecting plates can be placed in a vertical state, so that most of sunlight irradiated into the greenhouse irradiates onto crops planted in the greenhouse. Therefore, the sunlight is not wasted, and technical measures for consuming excessive photovoltaic power are not needed.

The beneficial effects of the utility model are as follows:

the double-sided photovoltaic module is vertically arranged between two adjacent greenhouses, and the generated energy of the photovoltaic system is increased by additionally arranging the herringbone reflecting plates in the greenhouses; the Y-shaped reflecting plate almost totally reflects the received sunlight on the photovoltaic plate and crops, and the sunlight is not reflected into the air, so that the air is free from light pollution, and reasonable lighting required by the crops is ensured.

In addition, by adopting the structure of the utility model, the occupied area of the photovoltaic photoelectric conversion device can be reduced, the installation space is saved, the installation cost is reduced, and the generation income of the photovoltaic module is increased by the design and the utilization of the herringbone reflecting plate, so that the overall income is improved.
