Description
Technical field
The present invention relates to marine tidal-current energy technical field of power generation, relate in particular to a kind of motor cover of tidal current energy generating equipment.
Background technology
Trend mainly refers to the regular seawater stream of following tidal phenomena and produce, and trend changes its size and Orientation twice every day. Marine tidal-current energy is different from morning and evening tides, morning and evening tides is the seawater lifting that flood tide and ebb cause, trend is the horizontal movement of seawater, the entrained energy of morning and evening tides is potential energy, can adopt the modes such as generating that construct a dam to store water to be used, marine tidal-current energy generating is directly to utilize the mechanical devices such as tidewater water impact impeller to drive generator work to generate electricity.
Compare with conventional energy resource, marine tidal-current energy has the following advantages: clean renewable; Energy gross reserves is large; Change regular measurable; Do not need to block Hai Jianba, and generating set is all immersed in seawater conventionally, less on marine organisms impact, can not produce three-waste pollution to environment, there is not the problem such as farmland, immigration allocation that takies common in conventional hydropower construction yet.
Owing to possessing above-mentioned advantage, the exploitation of marine tidal-current energy is by pay attention to day by day. Marine tidal-current energy resource is the important supplement of future source of energy, particularly significant in the energy supply that solves island. The capacitation efficiency of current marine tidal-current energy generator group is lower, and the advantage of vertical axis TRT is in the time that direction of tide is contrary, all to generate electricity, and has certain advantage. The efficiency of partly covering vertical-axis tide energy generating set and can effectively improve marine tidal-current energy generator group in this project, improves the utilization rate of marine tidal-current energy, promotes the exploitation of this new forms of energy of marine tidal-current energy.
The defect of conventional marine tidal-current energy generator group is at present: the TRT that adopts common horizontal shaft water-turbine, trend flow direction perpendicular to turbine shaft to time, the blade rotation direction of the hydraulic turbine will have time and the incoming flow opposite direction of half, incoming flow hinders the rotation of the hydraulic turbine on the contrary, reduces its capacitation efficiency. The device such as its motor cover uses metal material, is easily subject to the corrosion of seawater, causes the inner seawater that infiltrates of device.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of motor cover of tidal current energy generating equipment, and motor shield structure is simple, and amount of parts is few, and cost is low and water-tight corrosion-proof is respond well.
Of the present invention is that art technical problem can be solved by following technological means: a kind of motor cover of partly covering tidal current energy generating equipment, motor cover is the cover body structure of a hollow on the whole, its roof and sidewall are one-body molded, and bottom is fixed with the base plate for mounting teeth roller box and generator, sidewall is fixedly connected with base plate watertight, and cover body top outer is provided with measurement of rate of flow module.
Preferably, measurement of rate of flow module can adopt flow rate of water flow determinator Pitot tube.
Pass for the ease of cable, the both sides of motor cover are provided with cable aperture, pass for the cable being connected with energy storage device with generator, and cable aperture place is provided with watertight structure. This watertight structure is preferably the seal washer of waterproof anti-corrosion.
Same, pass through for the ease of connecting axle, on base plate, be provided with the axis hole that the rotating shaft that is connected with gear-box for the hydraulic turbine is passed through, axis hole place is provided with watertight structure. This watertight structure is similarly the seal washer of waterproof anti-corrosion.
Between sidewall and base plate, preferably adopt welding manner to be connected.
The cross section of cover body is the ellipse of ratio of semi-minor axis length between 2-4, and whole cover body is the housing of cylindroid shape.
Motor cover preferably adopts glass-reinforced plastic material to make.
Usefulness of the present invention is: motor cover adopts watertight structure, can follow the together submerged work of whole TRT, motor cover top is provided with flow velocity measuring device, can measure at any time flow rate of water flow, for the angle between oars of wing flap formula horizontal shaft water-turbine provides reference data; Whole cover body adopts the material of waterproof anti-corrosion to make, and life cycle is long, easy maintenance.
