Typhoon prevention device

Abstract

A typhoon prevention device comprises wind screens. Each wind screen comprises a framework and a plurality of blades. The plurality of blades are installed in the corresponding framework obliquely; the plurality of blades are arrayed in sequence; an interval is arranged between every two adjacent blades; each framework is fixed to the ground. The typhoon prevention device also comprises a supporting structure. The supporting structure comprises stand columns and a wirerope mesh. The stand columns are fixed to the ground through bases; the wirerope mesh is arranged among the stand columns; a plurality of the wind screens are fixed to the wirerope mesh; the lower ends of the wind screens are fixed to the ground; every two adjacent wind screens are fixed together. The typhoon prevention device has the beneficial effects that the rotatable blades fulfill the function of changing the wind direction when the typhoon comes, so that direct damage brought by the typhoon is reduced, in the absence of the typhoon, the blades are rotated to change the direction, thus the effect of normal ventilation is achieved, the structure is simple, thus manufacturing or building is easy, the typhoon prevention device can be used for a long time and can prevent multiple typhoons after being built once, and no repeated investment is needed.

Description

technical field [0001] The invention relates to the field of disaster prevention and control, in particular to a typhoon prevention device. Background technique [0002] A tropical cyclone with a central sustained wind speed of 12 to 13 (that is, 32.7 meters to 41.4 meters per second) is a typhoon or hurricane (hurricane), which is a tropical cyclone formed on a vast sea above 26°C in the tropics or subtropics. Every year in summer and autumn, many violent storms called typhoons will be generated on the Northwest Pacific Ocean adjacent to our country. Some of them dissipate at sea, and some land on land, bringing violent storms and rain, which is a kind of natural disaster. The typhoon caused serious damage to the places it passed through: the road facilities and buildings in the city were severely hit, tens of thousands of trees, traffic signs, street lights collapsed, and even caused casualties; a large number of houses in the countryside collapsed, aquatic products Farmi...

AI Technical Summary

Problems solved by technology

The typhoon caused serious damage to the places it passed through: the road facilities and buildings in the city were severely hit, tens of thousands of trees, traffic signs, street lights collapsed, and even caused casualties; a large number of houses in the countryside collapsed, aquatic products Farming losses were exhausted, trees were uprooted, especially economic crops such as fruit trees, seedlings, and rice were damaged by strong winds, resulting in huge economic losses for farmers

However, at present, typhoon disasters are mainly dealt with in passive forms such as monitoring, forecasting and early warning before landing, investigation of potential safety hazards, avoidance during landing, and rescue measures after landing, and no active and effective typhoon prevention device has yet appeared.
