Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, a variable speed system for a wind heating device includes a cavity filled with water in the wind heating device, two discs for transmission, and two shafts.

[0017] In a cavity filled with water, there are two disks, disk A1 and disk B2, the distance H between the two disks is 1~3 mm, and the two disks are equipped with blades on their opposite surfaces . The two disks are connected to the outside world through the axis A3 and the axis B4 respectively. Axis A is connected to the blades of the wind turbine. When the blades of the wind turbine rotate under the action of the wind, the axis A3 rotates. When it reaches a certain speed, it can drive the disk B2 to rotate under the action of fluid viscosity, thereby driving the axis B4 to rotate, and the axis B4 A mixing bucket is connected, and the fluid in the mixing bu...

Abstract

The invention relates to a speed changing system for a wind power heating device. Two discs for driving are arranged in a cavity respectively and connected with wind turbine blades and a stirring barrel respectively through shafts, when the disc which is connected with the wind turbine blades rotates to a certain rotating speed, the disc which is connected with the stirring barrel is driven to rotate under the action of fluid viscosity, and a fluid in the stirring barrel can be heated. The distance H between the two discs is 1-3mm and opposite surfaces of the discs are provided with blades. According to the speed changing system for the wind power heating device, the shaft of the disc which is connected with the wind turbine blades rotates to heat water in the cavity, when wind power is increased, the disc which is connected with the wind turbine blades can drive the disc which is connected with the stirring barrel to rotate, and a stirring plate in the stirring barrel can be driven through the shafts to heat the fluid. Therefore, flexible starting and simultaneous heating can be achieved, especially, the fluid in the cavity can be heated, and the two discs are slightly close so that the heating efficiency is high under extremely high friction function. When wind power is increased, the shafts drive the stirring barrel for heating, and therefore, loads are adjusted and wind energy can be fully utilized.

Description

technical field [0001] The invention relates to a device driven by a wind turbine that can be started at a low speed and simultaneously heats up, in particular a speed change system for the heating device. Background technique [0002] There are a lot of situations in industrial production and daily life that require the use of low-grade heat energy, such as domestic hot water, heating, heating of biogas digesters, heating in aquaculture, and heating of oil for transportation and so on. At present, high-grade thermal energy resources such as electricity, gas or coal are used in these fields, which not only causes great pollution but also great waste. [0003] The use of wind energy to generate heat is to convert wind energy into mechanical energy, and then the mechanical energy is directly converted into heat energy. This method is about 60% higher than the wind energy utilization rate of wind power generation, which is a form of wind energy utilization with the highest...
