Description
Technical field
The present invention relates to energy by ocean current technical field of power generation, specifically a kind of new and effective ocean current energy generator being convenient to lay.
Background technique
Energy by ocean current is a kind of rich reserves and regular governed ocean energy, utilizes energy by ocean current to carry out generating electricity and always be that the technical barrier of capturing is made great efforts in countries in the world.Current ocean current energy generator is generally made up of fixing device, wheel blade mechanism, driving mechanism and generator, by being the mechanical energy of impeller by the kinetic energy of ocean current, then changes electric energy into by driving mechanism and generator.But current ocean current energy generator is generally carry out scene fix in seabed and install, and construction cost is very high, and general electricity generating device energy by ocean current utilization ratio is lower, affects larger by current direction change.
Summary of the invention
In order to overcome, existing ocean current energy generator construction cost is high, ocean current utilization ratio is low, affect large shortcoming by current direction change, the invention provides a kind of new and effective ocean current energy generator being convenient to lay.This device is an entirety, only needs to assemble on the coast directly to sink to seabed afterwards, and construction cost is very low.Joining unit can make more ocean current by electricity generating device, and when less change occurs current direction, does not affect the normal work of device.Subtract resistance unit and can reduce wheel blade resistance, improve energy by ocean current utilization ratio.
The technical solution adopted for the present invention to solve the technical problems is: device is the entirety of a specular, with the middle vertical plane of the center line of rotating shaft for symmetry plane; Joining unit is the wedge shapes of two openings towards ocean current, and be cambered surface by the inclined-plane that ocean current impacts, this cambered surface still can realize the function of confluxing when current direction changes, joining unit is positioned at both sides, device ocean current ingress and with fixed unit connecting place for protrude joinery and its construction, contacts completely bottom joining unit with the top subtracting resistance unit; Subtracting resistance unit is ramp structure, and it meets the inclined-plane impacted by ocean current is cambered surface, subtracts the tip edge of resistance unit and the centerline parallel of rotating shaft and is positioned at same level, subtracts two ends, resistance unit left and right and fixed unit connecting place is protrusion joinery and its construction; Fixed unit is rectangular structure, and upper half part of its recessed joinery and its construction is connected with the protrusion joinery and its construction of joining unit, and lower half portion of its recessed joinery and its construction is connected with the protrusion joinery and its construction subtracting resistance unit; Joining unit, subtract resistance unit and be connected by joinery and its construction as a whole with fixed unit, and three unit are the hollow structure of particular design, only need the gross weight of control gear suitable, ensure that it can not be washed away by the ocean current of local Peak Flow Rate when specified sea areas entirety lays; Blade is connected with rotating shaft, and rotating shaft is connected with generator unit, and generator unit sealing is arranged on fixed unit inner hub location.
The invention has the beneficial effects as follows, the construction cost of device in seabed can be reduced, improve ocean current utilization ratio, reduce the impact that current direction changes.

As shown in the figure: 201-joining unit; 202-subtracts resistance unit; 203-fixed unit; 204-blade; 205-generator unit; 206-rotating shaft.
Embodiment
In FIG, joining unit 201, subtract resistance unit 202 and be connected by joinery and its construction as a whole with fixed unit 203, and each unit is the hollow structure of particular design, only need the gross weight of control gear suitable, ensure that it can keep static when specified sea areas entirety lays; Blade 204 is connected with rotating shaft 206, and rotating shaft 206 is connected with generator unit 205, and generator unit 205 sealing is arranged on fixed unit 203 inner hub location, makes this device become the entirety that one is symmetry plane with the middle vertical plane of the center line of rotating shaft 206; Device will complete assembling on the coast, directly sink to seabed afterwards and will come into operation, eliminate the sky high cost that subsea construction is fixed and installs; In the course of the work, joining unit 201 place will converge more ocean current, ocean current only impacts the power blade be positioned at above rotating shaft 206 after subtracting resistance unit 202, blade 204 is made more efficiently to drive rotating shaft 206 to rotate, be the mechanical energy of impeller by the kinetic transformation of ocean current, the mechanical energy of impeller is delivered to generator unit 205 by rotating shaft 206 afterwards, thus is electric energy by changes mechanical energy, finally achieves energy by ocean current generating.
In fig. 2, fixed unit 203 is rectangular structure, upper half part of its recessed joinery and its construction is connected with the protrusion joinery and its construction of joining unit 201, lower half portion of its recessed joinery and its construction is connected with the protrusion joinery and its construction subtracting resistance unit 202, thus, three unit connect as a whole by joinery and its construction.
In figure 3, joining unit 201 is the wedge shapes of two openings towards ocean current, and is cambered surface by the inclined-plane that ocean current impacts; Cambered surface can make more ocean current by electricity generating device on the one hand, on the other hand when less change occurs current direction, does not affect the normal work of device, and cambered surface can also reduce the loss of ocean current impact to device simultaneously.
In the diagram, subtract resistance unit 202 for ramp structure, and be cambered surface by the inclined-plane that ocean current impacts, subtract the tip edge of resistance unit 202 and rotating shaft 206 centerline parallel and be positioned at same level, ocean current will not impact the resistance blade be positioned at below rotating shaft 206, thus decreases resistance when rotating shaft 206 is rotated.
