Wind driven generator for ship

Abstract

The invention aims at providing a wind driven generator for a ship. The wind driven generator comprises a wind turbine, a permanent magnet generator and a lifting rod, wherein the wind turbine is connected with a rotating shaft of the permanent magnet generator, so that a vertical wind generating set is formed, and the lifting rod supports the wind turbine and the permanent magnet generator and can be lifted up and down. The wind driven generator is simple and easy to realize on the ship, the offshore wind energy can be adequately used, so that the pollution to the sea when the ship uses the conventional energy can be reduced. In the case that a power device of the ship is broken, even the spare generating set, the emergency standby power, the storage battery and the like can not run normally, the lifting rod can be manually operated, so that the wind turbine or the small-size wind generating set can be lifted up to a preset height for generating electricity. Therefore, in the emergency case that the ship is lack of power, the electricity can be generated by the wind driven generator on the ship, so that that the influence to the normal work of a ship power system and an emergencyelectric equipment can be avoided, and the reliability and the life force of the ship power system can be enhanced.

Description

technical field [0001] The invention relates to a wind energy generating device in the field of clean energy. Background technique [0002] At present, the global petrochemical energy is gradually decreasing. As a non-polluting and infinitely renewable resource, wind energy is especially abundant on the sea surface. Using offshore wind energy to generate electricity on ships can effectively save traditional energy for ship power plants. consume. However, there are many factors affecting the application of wind power generation devices on ships, and it is difficult to popularize the application of wind power generation. The patent authorization announcement number is CN201778958U, and the title is "ship-borne liftable wind power generator tower", which provides a kind of ship-borne liftable wind power generator tower. The tower can be installed on various ships and is convenient for installation, disassembly, storage and transportation, but the device is not suitable for la...

The patent authorization announcement number is CN1887647A, and the name is "ship wind energy utilization device", which provides a wind energy utilization device based on the principle of an umbrella. The rotating shaft of the generator is inside a hollow cylinder, and the top of the hollow cylinder is controlled by a telescopic rod. The expansion and closure of the wind blades, but this device has a complex structure, is not easy to install and maintain, and is limited by the center of gravity of the ship, so it is difficult to be widely used on ships

The patent authorization announcement number is CN2031843U, and the title is "Cylindrical inner leaf vertical axis wind turbine wind wheel structure" provides an improved cylindrical vertical axis wind turbine wind wheel structure, which is simple in structure and can be used in a wide range. However, the patent does not specifically point out the combination of the wind rotor and the generator shaft, nor does it point out the fixed position and installation of the wind rotor and generator

The patent authorization announcement number is CN2135660Y, and the name is "Vertical Axis Tower Wind Power Machine", which provides a vertical axis tower structure wind energy utilization device composed of multiple groups of wind wheels connected in series. This device has a large installation height, strong starting wind force, The structure is simple and the overall performance is good, but in modern ships, the fan can only be used as an auxiliary machine. In the case where it is not suitable to use wind power generation devices, no effective solution is proposed here, and it takes up a lot of space on the ship, so it is difficult to implemented in modern ships

The patent authorization announcement number is CN201517467U, and the name is "sail-type vertical axis wind-powered engine", which provides a wind-driven engine that can expand the wind-receiving area of ​​the blade from the width and length, and can fully utilize the wind energy in the downwind area. , but this device cannot realize the collection of propeller blades, and the resistance it receives is relatively large during ship navigation, and it is difficult to be widely used
