技术领域technical field
本实用新型涉及一种提高大棚结构防强风破坏的装置，具体的说，是涉及一种大棚结构补气装置，用于将迎风面的空气补到屋顶背风面以减轻棚顶的负压影响。The utility model relates to a device for improving the protection against strong wind damage of a greenhouse structure, in particular to an air supply device for a greenhouse structure, which is used to supply air from the windward side to the leeward side of the roof to reduce the negative pressure effect of the roof.
背景技术Background technique
在我国东南沿海地区，特别是受台风影响地区，强风无论是对蔬菜大棚还是观光大棚的破坏影响都十分显著。强风经过棚顶时由于风速过快会使棚顶产生巨大的负压，以至于会对棚顶产生破坏，甚至会掀翻棚顶，在我国就发生过多起类似事件。如果单纯的从结构出发进行棚顶加固，不仅造成经济成本的增加，而且还会使结构上部偏重影响结构自身稳定性。所以采用一种简单经济的装置进行减小棚顶负压影响是很有必要的。In the southeastern coastal areas of my country, especially in areas affected by typhoons, strong winds have significant damage to vegetable greenhouses and sightseeing greenhouses. When strong wind passes through the roof, the wind speed is too fast, which will cause huge negative pressure on the roof, so that it will damage the roof, and even overturn the roof. There have been many similar incidents in our country. If the roof is reinforced purely from the structure, it will not only increase the economic cost, but also make the upper part of the structure more heavy and affect the stability of the structure itself. Therefore, it is necessary to use a simple and economical device to reduce the influence of roof negative pressure.
实用新型内容Utility model content
本实用新型的目的是为了克服现有技术中的不足，提供一种大棚结构补气装置，可减小强风下大棚结构屋顶所产生的负压，从而提高结构的整体安全性。该装置能有效地进行补气，同时设计、施工难度低、装置对结构本身影响小，经济成本低。The purpose of the utility model is to overcome the deficiencies in the prior art and provide a greenhouse structure air supply device, which can reduce the negative pressure generated by the roof of the greenhouse structure under strong wind, thereby improving the overall safety of the structure. The device can effectively supplement air, and at the same time, the design and construction are less difficult, the device has little influence on the structure itself, and the economic cost is low.
本实用新型的目的是通过以下技术方案实现的：The purpose of this utility model is achieved by the following technical solutions:
一种大棚结构补气装置，由进气口、钢丝软管、出气口、屋顶钢桁架、屋顶盖和墙体组成，所述墙体、屋顶钢桁架和屋顶盖组成大棚结构，所述进气口和所述出气口成对设置，进气口为喇叭形结构且设置在主迎风向的一侧墙体；出气口设置在屋顶盖的背风侧，每对进气口和出气口之间通过所述钢丝软管相连通。A greenhouse structure air replenishing device, which is composed of an air inlet, a steel wire hose, an air outlet, a roof steel truss, a roof cover and a wall, the wall, roof steel truss and roof cover form a greenhouse structure, and the air intake The air inlet and the air outlet are arranged in pairs, the air inlet is a trumpet-shaped structure and is arranged on the wall on the side of the main windward direction; the air outlet is arranged on the leeward side of the roof cover, and each pair of air inlet and air outlet passes through The steel wire hoses are connected.
所述钢丝软管顺着墙体和屋顶钢桁架的下弦布置。The steel wire hose is arranged along the lower chord of the wall and roof steel trusses.
与现有技术相比，本实用新型的技术方案所带来的有益效果是：Compared with the prior art, the beneficial effects brought by the technical solution of the utility model are:
本实用新型补气装置是在迎风面风速，以及负压作用下使钢丝软管两端产生压差，促使迎风面的空气快速补到屋顶负压区。该装置无需提供外在的动力，结构简单易安装。由于钢丝软管为柔性材料，使其在布置上更加灵活方便，能做到既不影响结构受力，又不影响大棚本身的使用和美观。由于该装置结构简单，即可在大棚建造时加入该装置又可在已建好的大棚中加入使用。同时装置材料易于购买，成本低，所以该装置具有比较好的推广前景。The air supply device of the utility model is to generate a pressure difference at both ends of the steel wire hose under the action of the wind speed on the windward side and the negative pressure, so as to promote the air on the windward side to quickly replenish the negative pressure area of the roof. The device does not need to provide external power, and the structure is simple and easy to install. Since the steel wire hose is a flexible material, it is more flexible and convenient to arrange, and it can neither affect the structural force nor affect the use and appearance of the greenhouse itself. Because the structure of the device is simple, the device can be added when the greenhouse is built and used in the built greenhouse. At the same time, the device material is easy to purchase and the cost is low, so the device has relatively good promotion prospects.
