Simple and easy big-arch shelter of thermoregulation

Technical Field

The utility model belongs to farming facility field relates to a warmhouse booth.

Background

Factors influencing the growth of plants include temperature, illumination, humidity, nutrient elements and the like, and in traditional agricultural production, the temperature, illumination and air humidity of the plants completely depend on natural climatic conditions. The reaction curve of the plant growth speed along with the temperature is actually the reaction curve of the enzyme and the temperature, the plant body is a container for chemical reaction, and the reaction speed depends on the activity of the enzyme. Within a certain temperature range, the activity of the enzyme is positively correlated with the temperature, in a linear relationship, until an optimum temperature is reached, above which the activity of the enzyme is reduced and the growth of the plant is thus influenced. The plant growth reference temperature is the lowest temperature at which the plant performs photosynthesis, below which the plant stops growing. Too low or too high a temperature can cause the plant to stop growing. The optimal temperature for plant growth is the temperature at which the plant photosynthesis rate is highest, and decreases with plant maturity. The temperature required by different plants is different, the temperature required by the plants living in the tropical zone is higher, and the most suitable temperature is about 25-37 ℃; the most suitable temperature for the growth of the cold-zone plants is about 11-23 ℃. The temperature requirements of plants living in temperate zones are different between plants living in winter and plants living in summer. Plants grow fastest under optimal temperature conditions, but this is not the temperature at which plants grow most robustly. At the optimum temperature, the organic matter in the plant is consumed too much, and the plant grows slender and weak. Therefore, in production practice, robust plants are usually required to be cultivated at a temperature lower than the optimum temperature, which is called the coordinated optimum temperature. Experiments show that the vegetative growth of plants is best in the cyclic variation of higher temperature in the day and lower temperature at night.

In order to realize the cultivation of vegetables in advance, simple greenhouse cultivation technology is widely used in southern areas. The simple greenhouse is influenced by solar radiation and terrestrial heat, and has high temperature rise speed and good heat preservation effect. Therefore, the temperature needs to be adjusted in time according to the production conditions. In winter or spring, the temperature outside the shed is low. In the weather of solar irradiation, because the greenhouses are sealed, the temperature in the greenhouses is high, and the greenhouses are cooled by adopting a ventilation mode generally. In the prior art, the 'ground sweeping wind' is introduced around the greenhouse to reduce the temperature in the greenhouse, but cold wind directly blows plants, so that the plants are easily frozen. In order to avoid the freezing damage of plants, the prior art is provided with greenhouses with openings at the top and the upper part of the end surface.

In implementing the present invention, the inventor finds that there is at least one of the following problems in the prior art:

1. the existing simple greenhouse is ventilated by opening doors at the periphery of the lower part of the greenhouse and the lower part of the end surface, the temperature difference between the internal temperature and the external temperature of the greenhouse is large, and the periphery of the lower part of the greenhouse is directly opened, so that plants around the greenhouse are easily damaged by cold air, the growth is influenced, and even physiological diseases occur;

2. the end surfaces of the greenhouse are all open, although cold air can enter the greenhouse and the temperature in the greenhouse cannot be adjusted to be consistent, plants directly contact with the cold air and are easily subjected to cold damage, and the wind resistance and the rainstorm resistance of the greenhouse are greatly reduced due to the fact that the end surfaces are all open;

3. the vent is arranged at the top, after the vent is opened, the air fluidity in the greenhouse is poor, the uniform temperature reduction in the greenhouse needs to be realized, more ventilation structures need to be arranged, the wind resistance of the greenhouse can be reduced, the installation cost of the greenhouse can be increased, and the workload of farmers can be increased.

The switch type ventilation window is opened under the condition that ventilation is needed; the ventilation window is closed only under the condition of heat preservation without ventilation. In this embodiment, the opening and closing ventilation windows include end ventilation windows 111 located at two ends of the greenhouse and a top ventilation window 120 located at the middle section of the greenhouse.

The number of the end ventilation windows 111 is two, and the two end ventilation windows are respectively positioned at two ends of the greenhouse. The lower parts of the two end parts 110 of the simple temperature-adjusting greenhouse 100 are closed and are not ventilated. The tip ventilation window sets up the upper portion at the both ends tip 110 of simple and easy big-arch shelter 100 of adjusting temperature, when needing to the big-arch shelter cooling, opens top ventilation window 111, and the hot-air outflow of high pressure in the big-arch shelter, the inside and outside atmospheric pressure of big-arch shelter is balanced the back, and the air temperature in the big-arch shelter reduces gradually, and atmospheric pressure reduces, and cold air gets into the big-arch shelter from the tip ventilation window to mix with the hot-air in the big-arch shelter, and the temperature in the big-arch shelter is closed after reducing to preset temperature value.

The end-vent 111 includes a window frame on which a window door 112 is mounted. In the embodiment, the window frame is in a small-section round shape, the height of the window frame is 1/4-1/3 of the height of the greenhouse, and the window door 112 is hinged with the lower frame of the window frame; the window and door 112 is connected with the upper frame of the window frame through a window and door connector 113. The window and door connecting member 113 may be a connecting rope or a connecting rod, and the length thereof may be adjusted as required, for example, knotting the connecting rope, or the connecting rod may be a folding rod or a telescopic rod. The end ventilation window 111 is closed, and the window door 112 is clamped on the window frame; when the end ventilation window 111 is closed, the window/door connecting member 113 pulls the window/door so that the window/door 112 is parallel to the ground or the window/door 112 forms an angle with the ground. The window 112 includes a frame body, and a plastic film is attached to the frame body.

The number of the top ventilation windows 120 may be one or more, and the top ventilation windows 120 are specifically arranged according to the length of the simple temperature-adjusting greenhouse 100, in this embodiment, fig. 1 shows a case where there is one top ventilation window 120. The top ventilation window 120 is arranged in the middle section of the temperature-adjusting simple greenhouse, namely between two end faces of the greenhouse. The top ventilation window 120 is a ventilation window provided from the upper portion to the top of the middle section of the greenhouse. The opening and closing of the top ventilation window 120 is adjusted by a top window slide rod 121. The roof window sliding bar 121 is in sliding fit with the cross beam 102. The roof window slide bar 121 is arched, and the radian thereof is matched with the radian of the arched support 101.
