Description

Technical Field:

[0001] The utility model relates to the technical field of ventilators, and more specifically to a special circulating ventilation device for greenhouse vegetable planting bases. Background Art:

[0002] A greenhouse, also known as a hothouse, is a facility that can transmit light and keep warm (or heat up), mainly used for cultivating plants such as warm-season vegetables, flowers, and forest trees in seasons when it is not suitable for plant growth, so as to provide a suitable growth period and increase yields. In order to ensure air circulation and prevent pests and diseases, existing greenhouses are generally equipped with a ventilation system, which is divided into two types, including natural ventilation and forced ventilation. Forced ventilation is to force air to flow through equipment such as ventilators to achieve rapid air exchange, so as to achieve the purpose of ventilation and cooling. Therefore, the main component of its forced ventilation system is the ventilator. At the same time, because the main components of the greenhouse are steel frameworks, glass panels or films, etc., most of the ventilators dedicated to greenhouses are generally suspended on the framework of the greenhouse (the steel crossbeam on the upper part of the greenhouse) by two steel wires. The advantage of using the suspension method is that it is convenient for installation, but during the operation of the ventilator, the ventilator will vibrate, and the vibration will cause the ventilator to displace and sway, posing a safety hazard. Therefore, it is necessary to design a special circulating ventilator for greenhouses that is convenient for installation and stable in operation at the same time. Content of the Utility Model:
