Description

Greenhouse

Technical Field

The utility model relates to a big-arch shelter ventilation field specifically relates to a big-arch shelter.

Background

The greenhouse is frame film covering equipment with excellent heat insulation performance common in daily life of people, and can be roughly divided into a single greenhouse and a multi-span greenhouse or a common greenhouse and an intelligent greenhouse. The greenhouse is originally a special facility for vegetable production in agriculture, and the application of the greenhouse is increasingly wide along with the development of production of people. At present, the greenhouse can be applied to various fields such as agricultural production, forestry production, breeding industry and the like. The greenhouse mainly comprises a framework and heat-insulating films, wherein the framework is made of materials such as bamboo and wood rods, cement rods, light steel pipes or pipes and the like, and one or more layers of heat-insulating films are covered on the framework, so that a greenhouse space of the greenhouse is formed. The outer film of the greenhouse can well prevent the loss of carbon dioxide generated by the growth of internal products, so that the greenhouse has a good heat preservation effect.

The ventilation of the greenhouse is an especially important link in the use process of the greenhouse, and the normal growth of products in the greenhouse can be ensured only after the ventilation of the greenhouse is completed. At present, the ventilation openings of the traditional plastic greenhouse are arranged on two sides of a gutter or on the sides around the bottom of the greenhouse. The vent of arch big-arch shelter all sets up the both sides or both ends at the big-arch shelter bottom, but the hot-air in the big-arch shelter rises, can upwards concentrate the big-arch shelter top, and the vent of current big-arch shelter bottom is difficult to discharge the hot-air of concentrating the big-arch shelter top, leads to the ventilation efficiency of big-arch shelter low, and the temperature in the big-arch shelter is high or not down. If the top of the greenhouse is not provided with the ventilation opening, the phenomenon of dripping water in the greenhouse can also occur, so that the product is damaged. In addition, by means of the ventilation opening of the bottom air and the existing greenhouse, outdoor cold air can directly enter the greenhouse from the bottom of the greenhouse, the ground temperature is low, the activity of root systems of products such as vegetables is poor, absorbed nutrients and moisture are reduced, normal growth of the products is not facilitated, and physiological diseases are easy to occur. Moreover, after the cold outdoor air enters the greenhouse, the cold outdoor air can directly contact fruits close to the ground, and the problems of fruit cracking and the like are increased. The current intelligent greenhouse is complete in equipment, can better solve the ventilation problem of the greenhouse, but the intelligent greenhouse is high in cost and complex in structure, and does not meet the production requirements of public farmers.

In order to overcome the defects, the top of the greenhouse is arranged to be a structure capable of being opened and closed in a common method at present, when ventilation is needed at the top of the greenhouse, people climb onto the top of the greenhouse, manually open an opening at the top, and close the opening after the ventilation is finished. However, this method is time-consuming and labor-consuming to operate and poses a certain risk to the operator.

The existing greenhouse is not enough to lack a convenient and practical ventilation device.
