Description

An energy-saving solar greenhouse

technical field

The utility model relates to an energy-saving solar greenhouse, which belongs to the technical field of facility agricultural engineering.

Background technique

The solar greenhouse is an agricultural facility project. It uses the south slope to absorb solar radiation, the north wall to store heat and keep warm, and the back slope to keep warm, creating an environment suitable for crop growth in winter. It is the most widely used in northern my country. After decades of improvement and development, solar greenhouses have various shapes and supporting equipment, each with its own advantages and disadvantages. Technical research mainly focuses on solving the problems of lighting and heat preservation in winter, and less consideration is given to the cooling and dehumidification of the greenhouse. With the wide application of greenhouses, actual production has put forward the requirements for cooling and dehumidification of solar greenhouses. The indoor temperature of the solar greenhouse in summer is too high, which makes it impossible to plant in summer; while the indoor humidity in winter and spring is too high, which leads to serious crop diseases and insect pests. In order to solve the problem of cooling and dehumidification, some researchers have transplanted the practice of multi-span greenhouses, adding external sunshade and forced cooling system to the solar greenhouse, which can solve the problem of cooling, but increases energy consumption, which is not conducive to popularization. The method of ventilating and dehumidifying the top seams can solve the problem of excessive humidity, but the labor intensity is high, and the plastic film is easily damaged, which is not conducive to the management of the solar greenhouse.

Contents of the invention

The purpose of the utility model is to provide an energy-saving solar greenhouse to solve the problems of cooling and dehumidification of the greenhouse in summer.

In order to achieve the purpose of this utility model, the technical solution adopted includes: heat preservation back slope 2, south slope, two side walls, it is characterized in that, be provided with a vertical wall body between heat preservation back slope 2 and south slope, in The vertical wall is provided with a roof window.

In the above-mentioned energy-saving solar greenhouse, the roof window is a continuous outward opening type.

In the above energy-saving solar greenhouse, the roof window is equipped with an electric opening device.

The energy-saving solar greenhouse provided by the utility model has good lighting in winter, a complete back wall, good heat preservation and heat storage, natural ventilation and cooling in summer, and an external sunshade system. Compared with the prior art, the greenhouse is more energy-saving, and the controllability of indoor temperature and humidity is better.

Description of drawings

Fig. 2 is a schematic diagram of the improved lighting angle of the energy-saving solar greenhouse;

Fig. 3 is a schematic diagram of natural ventilation of the energy-saving solar greenhouse.

Detailed ways

As shown in Figure 1, 1 is the thermal insulation rear wall, 2 is the thermal insulation rear slope, 3 is the roof window (or "insulation window"), 4 is the south slope frame, 5 is the south slope film curtain, and 6 is the south slope. For slope insulation quilt, 7 is the fixed film for the south slope, 8 is the outer sunshade skeleton, and 9 is the outer sunshade net. The south slope frame 4, the south slope rolling film curtain 5, the south slope thermal insulation quilt 6, the south slope fixed film 7, the outer sunshade skeleton 8 and the outer sunshade net 9 constitute the south slope.

It can be seen from Fig. 1 that a vertical surface, that is, a vertical wall, is added between the thermal insulation back slope 2 and the south slope frame 4 of the energy-saving solar greenhouse, and a continuous outwardly opening roof window 3 ( That is, a row of open windows), which can form convective ventilation with the roll film window in the middle of the south slope (as shown in Figure 3), and cooperate with the external sunshade net 9, which has a good cooling effect in summer; when it is necessary to dehumidify, it can also pass through Properly open the top window 3 to solve. The top window is opened by the motor, which reduces the workload of manual seam ventilation, improves the top insulation, and improves work efficiency. At the same time, avoid opening holes in the north wall, which is conducive to the heat storage and heat preservation of the north wall in winter. In addition, the elevation angle of the south slope of the solar greenhouse with this shape is increased, as shown in Figure 2, β is the lighting angle of the prior art, and Φ is the lighting angle of the energy-saving solar greenhouse, Φ>β, which is conducive to absorbing solar radiation in winter The increase has made a great contribution to energy saving.

Therefore, the energy-saving solar greenhouse with the above-mentioned structure solves the problems of cooling and dehumidification in the prior art, and at the same time, it is beneficial to increase the amount of sunlight in winter.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions of the new utility model without departing from the spirit and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
