Description

A solar greenhouse

technical field

The invention relates to the field of solar energy, in particular to a solar greenhouse.

Background technique

my country is a large agricultural country, but also a populous country. Although my country's crop production has remained at a high level all year round, due to my country's large population, per capita grain production is still not high, and the food security situation is still grim. The greenhouse has the function of light transmission and heat preservation, which can make the plants that are not suitable for this season or low temperature grow normally. Greenhouses have been widely used, especially in the cultivation of greenhouse vegetables, which have achieved extensive application and development. However, there are still many shortcomings in the traditional solar greenhouse, such as the low utilization rate of sunlight, the excessively high temperature during the day and the low temperature at night are also unfavorable to the growth of vegetation, these problems greatly restrict the promotion of greenhouses And use, bring great trouble to agricultural production.

Contents of the invention

The object of the present invention is to provide a solar greenhouse, which increases the utilization of sunlight and simultaneously solves the problem that the temperature of the greenhouse is too high during the day and the temperature is too low at night.

In order to achieve the above object, embodiments of the present invention adopt the following technical solutions:

Further, the tracking device includes an automatic tracking system, a motor, a motor base, a motor driven wheel, a motor driven wheel driven belt, a guide rail, a slider and a bracket; the automatic tracking system and the motor are located on the motor base, and there is a bracket under the motor base , the motor is connected to the motor driven wheel, the guide rail is located on the arc-shaped roof, the guide rail is arc-shaped, there are two sliders on the guide rail, the guide rail is connected to the heat collector through the slider, and the motor driven wheel is connected to the slider through the motor driven wheel belt. The tracking device can try to ensure that the sunlight hits the solar collector vertically.

Further, the solar collector is a solar vacuum tube. The solar vacuum tube has high thermal efficiency and good effect.

Further, several storage batteries are also arranged in the shed. The storage battery can store the electrical energy converted by the solar collector and use it for other devices when needed.

Further, the solar collector is made of transparent material. When the solar collector is made of a transparent material, light that is not absorbed by the solar collector can pass through it and enter the greenhouse to further utilize sunlight.

Further, the shed body and roof are made of transparent materials. When the shed body and the shed roof are made of transparent materials, sunlight can be allowed to enter the shed to further utilize the sunlight.

Further, the heat collector is a hollow tube made of metal. The metal hollow tube has a good heat conduction effect, and can transfer the temperature of the solar converter to the hollow tube well, and then transport the heat into the greenhouse through the medium in the hollow tube.

Further, the roof is arc-shaped. The curved roof is conducive to the realization of the tracking system function.

Further, the guide rail is arc-shaped. The guide rails of the house type cooperate with the curved roof, which is conducive to the realization of the function of the tracking system.

Further, a lighting device is also provided in the shed. The lighting device installed in the shed can realize the lighting in the shed at night, and the temperature generated by the lighting device can also increase the temperature of the shed at night to prevent the temperature of the shed from being too low at night.

Beneficial effects: a solar greenhouse provided by the present invention can track the azimuth of the sun by setting a tracking device on the roof, and control the solar collector on the tracking device through the tracking device, so that when there is sun, it can be as far as possible Allow sunlight to irradiate the solar collector vertically to maximize the use of sunlight. The heat collector can collect the heat brought by the sunlight, and can also collect the heat generated when the solar collector works, and convert the heat into the heat storage pool inside the greenhouse, and improve the temperature of the greenhouse through the heat dissipation of the heat storage pool. Temperature, especially at night, the heat of the heat storage pool is diffused through heat conduction, which can well prevent the temperature of the greenhouse from being too low at night. The heat collector is placed outside the greenhouse to avoid excessive temperature during the day in hot weather. Because during the day, if the temperature is too high, the work of the heat collector is stopped, and the heat of the solar collector will not be brought into the greenhouse. If there is a storage battery inside the greenhouse, the electric energy converted by the solar panels can be stored and used by other devices when needed, achieving the goal of self-sufficiency in power, energy saving and environmental protection in the greenhouse. Using the solar greenhouse provided by the present invention can increase the utilization of sunlight, thereby greatly increasing the temperature of the greenhouse; at the same time, it solves the problem that the temperature of the greenhouse is too high during the day and the temperature is too low at night, and achieves the self-sufficiency of power in the greenhouse, energy saving and environmental protection. .
