Description
Technical Field
The utility model relates to a revolving frame of ocean current electricity generation belongs to ocean current power generation equipment technical field.
Background
In ocean current power generation, the tidal energy of ocean current is converted into mechanical energy and then into electric energy by taking power through a rotating frame structure. The existing hydroelectric generation devices are numerous, but the existing hydroelectric generation devices are rarely used for ocean currents, the direction of water flow is single in a one-way water flow state (river), when a rotating frame is designed, a transverse shaft is mainly designed, a part of the rotating frame is in water, a part of the rotating frame is on the water surface, and energy conversion is realized through one-way water flow impact. In the vertical shaft power generation device, there is a structure using a support rod and a blade, such as CN201120376667.3 a vertical shaft water flow power generation system. For example, CN201710418897.3 an ocean current power generation device, the impeller structure includes a blade frame and a plurality of blades, and the plurality of blades are rotatably installed on the blade frame through an installation hole and an installation groove structure, and are in a louver structure.
These structures are ideal designs, and are not practical for ocean current power generation in actual oceans. The ocean current power generation equipment needs to complete the following steps: optimal conversion rate and convenient maintenance and service. However, the prior art has no mature design and report, and the reason is that the prior art is in an ideal design stage and does not really contact with ocean currents.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a among the ocean current power generation, can effectively improve the rate of conversion, conveniently maintain the revolving frame of maintenance.
In order to achieve the above purpose, the utility model adopts the technical proposal that: the utility model provides a revolving frame of ocean current power generation, includes an installation axle, installs a plurality of sets of revolving frame on the installation axle, and every set of revolving frame has four fans with the installation axle equipartition, staggers an angle between adjacent two sets of revolving frame's fan and the fan.
The structure as given in CN201710418897.3 an ocean current power generation device has the following problems:
1. the triangular frame is adopted, the technical personnel in the field understand that the rotating frame adopts 2, 3, 4 or more structures and the like, and the ideal energy conversion can be realized as long as the rotating frame is uniformly distributed by the middle shaft, which is not so substantial, when ocean current flows in a certain direction, only one fan which performs positive work is substantially, and two fans which perform negative work are substantially, and the uniform distribution results in that each fan is 120 degrees apart, when one fan which is close to the incoming flow direction along the rotating direction starts to perform work, the fan which is positioned at the same side is blocked by the frame and does not perform work, and the third fan is in a state that the right part is almost vertical to the water flow, the return resistance is large, and in an extreme case, when the fan which performs work is close to the incoming flow direction, the other two fans are positioned at the return side and form resistance by the impact of the water flow.
2. Whether the frame of 4 fans can be used or not is only adopted, and long-time marine tests show that the 4 fans can ensure balance in pairs, however, when 1 fan (including 2 fans doing positive work and negative work on the upstream) mainly does work, a vortex is formed between the 4 fans and the other fan shielded by the 4 fans, and the larger the fan surface is, the longer the fan arm is, the more serious the fan arm is. The power taking process caused by the influence is small and large, so that power generation is not smooth, and the generator is easy to burn. It is known that the longer the moment arm, the better the force taking effect, however, this is not the case, and it is critical to eliminate the eddy current effect so that the generator operates smoothly and a reasonable power generation can be achieved.
Therefore, adopt a plurality of sets of runing frame among our technical scheme, four fans of every frame, with the shared space reduction of each fan of runing frame, and adjacent upper and lower two sets of setting of staggering, can effectual elimination vortex influence for the whole frame that the runing frame constitutes is more steady when promoting the installation axle, thereby makes the operation of generator more steady.
Further, the cross section of the mounting shaft is polygonal.
Further, the cross section of the mounting shaft is octagonal or dodecagonal.
Furthermore, the rotating frame is formed by connecting two parts, wherein one part comprises two fans arranged on one surface and a vertical fan vertically connected with the two fans, the other part comprises a vertical fan II positioned on one plane with the vertical fan and a connecting frame used for connecting the two fans, the vertical fan II is vertically connected with the connecting frame, and a polygonal surrounding structure matched with the polygon of the cross section of the installation shaft is reserved between the two parts of the rotating frame.
The installation axle adopts polygonal design, especially octagon or dodecagon, through the transformation to the rotation frame, lets it can the successive layer installation, ensures to install and targets in place, moreover, octagon or dodecagon's design, can effectual equipartition rotating frame, for example adopt the octagon, design four layers rotating frame, and the dodecagon layering can be more. However, the purpose of the design is still to make the whole structure stagger by 30 or 45 degrees in the water flow, so as to realize continuous power take-off effect, and make the power take-off more stable, so as to ensure stable power generation.
Furthermore, the vertical fan of the rotating frame is connected with the two fans connected with the vertical fan through a reinforcing rod, and the vertical fan II is connected with the connecting frame through a reinforcing rod.
Further, the installation axle is higher than the height of a revolving frame of the surface of water, and every group revolving frame's acanthus leaf adopts the proportion to be less than the material of water and makes, can freely float in the surface of water when making every group revolving frame installation, when installing a set of down, goes up the weight of upper strata and naturally pushes down lower floor's revolving frame, installs the balancing weight on the topmost layer revolving frame.
Furthermore, the uppermost layer of the rotating frame is below the water surface, and the height from the water surface is not less than 50 cm.
The uppermost layer rotating frame is adjusted through the balance weight, so that the uppermost layer rotating frame is sunk to a position at least 50cm below the water surface, and under an ideal condition, the uppermost layer rotating frame is optimal about 1 m below the water surface according to the rising tide and falling tide rules and the influence of wind waves, so that the impact of the wind waves can be reduced, and the energy of ocean currents can be received possibly.
The beneficial effects of the utility model reside in that: the structure is reasonable, the problems that the power generation is not stable and the engine is burnt in the prior art are solved, and the conversion rate is higher due to stable power take-off; the design of the rotating frame and the shaft ensures that the installation and the maintenance are more convenient.
