Wind power generation wind collecting device based on venturi tube

Abstract

The invention discloses a wind power generation wind collecting device based on a venturi tube. A wind inlet of the venturi tube is provided with a wind collecting port, and the venturi tube and the wind collecting port are fixed on a fixing support. A blade turbine is mounted at the position, with the smallest diameter, of the middle of the venturi tube. Guide plates are arranged at the peripheryof the wind collecting port and are inclined towards an air outlet. A pressure relief opening is formed in the wind collecting port, and a pressure relief valve is mounted on the pressure relief opening. According to the device, the wind collecting port needs to be used facing the wind direction, the wind collecting port is additionally formed in the wind inlet of the venturi tube, natural wind can be collected, the wind speed is increased, the guide plates are additionally arranged at the periphery the wind collecting port to guide natural wind which does not enter the wind collecting port around, and the natural wind is prevented from influencing a negative pressure area behind the wind collecting port; and meanwhile, the pressure relief opening and the pressure relief valve are arranged at the wind collecting port, the pressure relief valve is opened when natural wind is too heavy, and surplus wind collected in the wind collecting port can be discharged from the pressure relief opening.

Description

technical field [0001] The invention relates to a wind power generation wind collection device based on a Venturi tube, belonging to the technical field of wind collection power generation equipment. Background technique [0002] Wind power is the conversion of wind kinetic energy into electrical energy. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. my country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kW, of which, the wind energy reserves on land are about 253 million kW (calculated from the height of 10m above the ground on land), and the wind energy reserves that can be developed and utilized at sea are abo...

Problems solved by technology

Existing wind power generation equipment can generate electricity with normal efficiency when the wind is strong, but most windy areas are not always full of strong winds, and wind power generation equipment cannot generate power with normal efficiency in some light wind conditions. Low can not meet the operating requirements of wind power generation equipment, wind power generation equipment is directly in a stagnant state, so the present invention studies a wind power generation wind collection device based on Venturi tube to solve the above problems
