High-reliability offshore wind power generation facility with heat dissipation function

Abstract

The invention relates to a high-reliability offshore wind power generation facility with a heat dissipation function. The high-reliability offshore wind power generation facility with the heat dissipation function comprises an installation base, a power generation box, a generator, a power generation shaft and multiple fan blades, and further comprises an adjusting mechanism and a heat dissipationmechanism. The adjusting mechanism comprises a lifting plate, a lifting rod, two limiting assemblies, two moving assemblies and two adjusting assemblies. Each moving assembly comprises an air cylinder, a piston, a moving rod, a moving plate, a hinge joint rod and a first spring. The heat dissipation mechanism comprises a support, two transmission assemblies and two heat dissipation assemblies. Each heat dissipation assembly comprises a filtering screen, a rotating shaft, two first bearings and multiple blades. According to the high-reliability offshore wind power generation facility with theheat dissipation function, the function that the height of the power generation box is adjusted is fulfilled by the adjusting mechanism, the probability of the phenomenon that the fan blades are corroded and damaged is reduced, and therefore the reliability and the safety of the offshore wind power generation facility are improved. The function of heat dissipation of the interior of the power generation box is fulfilled by the heat dissipation mechanism, and the phenomenon that due to the fact that the interior of the power generation box is excessively hot, the normal operation of the generator is affected is avoided.

Description

technical field [0001] The invention relates to the field of new energy sources, in particular to a high-reliability offshore wind power generation device with a cooling function. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of components such as wind rotors, generators (including devices), steering devices (tail fins), towers, speed-limiting safety mechanisms, and energy storage devices. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates to generate electricity under the drive of the wind rotor shaft. In a broad sense, wind energy is also solar energy, so it can also be said that wind power generators are generato...

Problems solved by technology

[0003] The power generation device of the existing offshore wind power generation equipment does not have a protective device, so that when the waves are large, the seawater is easy to hit the power generation device, causing corrosion of the power generation device, increasing the probability of damage to the power generation device, and reducing the risk of existing offshore wind power generation. The reliability and safety of the equipment, not only that, when the existing offshore wind power generation equipment is generating wind power, the heat generated by the generator is accumulated inside the generator box, causing overheating in the generator box and affecting the normal operation of the generator.
