Problems solved by technology

However, wind power generation has intermittent and fluctuating characteristics, and belongs to low energy density, poor stability, and inconvenient regulation of electric energy. However, the existing wind power generation device is a technology in which windmills directly act on wind turbines to generate power, which seriously restricts wind power generation. The development of their careers, they have the following problems in actual work:
[0003] 1. The current sent out is unstable and of poor quality, sometimes it is too much, sometimes it is too little, it is difficult to connect to the grid, it has an impact on the grid, and it is difficult to transmit it to the grid.
[0004] 2. Low efficiency, poor control ability,
[0005] 3. The structure is complex, and the material requirements for parts are high.
[0006] Fourth, the cost of power generation is high, the cost is high, the installation and maintenance are difficult, and the cost is high

Embodiment 1

[0025] Example 1, such as Figure 1 to Figure 5 As shown, there are four transmission shafts 17 arranged at linear intervals. Drive shafts 19 are correspondingly arranged on one side of the four transmission shafts. The mass of the gravity block 16 is 1000 kilograms, and the diameter of the outer wheel 25 is 1 meter. It is set at 3.14 m / s, the lifting height of the gravity block is 32 meters, and three-stage gear transmission is adopted. The first stage is the gear transmission in the pulley assembly, the second stage is the transmission gear and the driving gear transmission, and the third stage is the driving shaft and the generator. Transmission, the total transmission ratio is 1 / 25, the three-stage transmission efficiency is 97%, the total efficiency η total = 97% × 97 × 97% = 91.27%, the vertical axis fan is 2.5 meters high and 0.8 meters wide, The radius of rotation (half the length of the connecting rod) is 1.6 meters. When the wind speed is 4 m / s and the wind speed is ...

Embodiment 2

[0033] Embodiment 2, power transmission shaft 17 is eight, respectively arranges four on drive shaft both sides, and other each component structure is identical with embodiment 1, then output torque T goes out=2*T λ ×η total × i total = 2 × 4900 × 91.27% × 1 / 25 = 357.8 N m, then the output power of the generator in embodiment 2 P out = T out × n out / 9549 = 357.8 × 1500 / 9549 = 56.2kW .

[0034] If compared with Embodiment 1, the drive shafts on Embodiment 3 are still four and arranged at intervals on one side of the drive shaft on the same axis, when the total mass of the gravity block is doubled, the output power of the generator on the drive shaft is also Correspondingly doubled.

Abstract

The invention discloses an energy storage wind driven power generation device, which comprises a wind energy conversion mechanism, a hydraulic control mechanism, a lift mechanism, a gravity drive mechanism and an output mechanism, wherein the wind energy conversion mechanism comprises a vertical shaft air blower, a speed changer (5) and a hydraulic pump (6); the hydraulic control mechanism comprises a sequence valve (8), a relief valve (9), a distribution valve (10), a computer and a hydraulic controller (7); the hydraulic controller (7) consists of a regulating valve and a control valve; thelift mechanism comprises a hydraulic winch (12); the gravity drive mechanism comprises a drive shaft (17), a pulley combination body (14), a gravity block (16), a drive gear (18), an intermediate gear (21), and a hydraulic clutch (22); and the output mechanism comprises a drive shaft (19), a drive gear (20) and a generator (24). In the energy storage wind driven power generation device, wind energy is converted into hydraulic energy and then converted into gravitational potential energy for energy storage, and the gravitational potential energy is converted into electric energy, so that the intermittence and the fluctuation of wind power are avoided, the electric energy is stably output, and the energy storage wind driven power generation device is stable in power, more stable in transmission and high in wind energy utilization ratio, has no impact on a power grid, and is safely connected to the electric grid.

Description

technical field [0001] The invention relates to a wind power generation device, in particular to a high-power energy storage wind power generation device with stable output power, adjustable arbitrarily, no impact on the power grid, and safe grid connection. Background technique [0002] As we all know, wind power has many advantages, especially wind power is green and environmentally friendly, does not consume energy, is a new direction for the development of new energy, and has the most development value in the field of new energy. In recent years, my country's wind power has developed rapidly, and the installed capacity of wind power has also doubled year by year. However, wind power generation has intermittent and fluctuating characteristics, and belongs to low energy density, poor stability, and inconvenient regulation of electric energy. However, the existing wind power generation device is a technology in which windmills directly act on wind turbines to generate pow...
