The right side facing the current has a small stress area and small pushing force while the inverse facing the current has a great stress area and great pushing force. The transmission shaft is pushed to rotate to the side of greater force and the rotating transmission shaft drives the generator, thereby the purpose of generating electricity is fulfilled.

Description

A kind of tidal flow electricity generating device

Affiliated technical field

The utility model relates to the device that a kind of energy that utilizes tidal flow generates electricity.Thereby specifically directly utilize the energy of the tidal flow on coastal, island to drive the device that electric energy is obtained in generator work.

Background technique

Severe power shortage produces tremendous influence to the economic development of China, and energy shortage has become the outstanding problem that the world today influences economic development, and thermal power generation also can cause serious pollution to environment except consuming a large amount of non-renewable energy resources.Design a kind of non-renewable energy resources that do not consume, can not pollute, also do not need to build and build dam, the device that the flow energy that can directly utilize nature to exist generates electricity environment.

The model utility content

The purpose of this utility model is to provide a kind of to society to be located in the water, directly is that the generating of power is put with the tidal energy.

The utility model is achieved like this: it comprises the platform that floats on the surface, and anchor chain, anchor, the generator, the transmission shaft that are installed on the platform reach driving mechanism under water.

This driving mechanism is made up of sail post more than two couple who is fixed on the transmission shaft and the sail that is installed on the sail post, in its every pair sail, the sail installation direction of the left and right sides is just in time opposite, when one side flows the front for meeting water, opposite side just in time is the stream reverse side that meets water, the positive sail of stream that meets water is subjected to the area of water flow impact pressure effect big, and the sail of the stream reverse side that meets water is subjected to the area of water flow impact pressure effect little.

Its sail can be arranged to the web plate shape of arc, and grid framework and horizontal plane are vertically fixed on the sail post, and arc grid framework concave surface is the flow path direction that meets water, and all synthetic fiber canvas that can cover netted rack are being fixed in the top of grid framework concave surface.Also sail can be arranged to horn-likely, the horn mouth of this sail is the flow path direction that meets water.Be fixed in the front portion of sail post substantially horizontal, the front end that each sail is lived connects with cable wire, and to improve each sail post stressing conditions, the sail post is made the hollow type structure, makes the sail post produce corresponding buoyancy, suspends in water, to alleviate the stressed of platform.

Owing to of the present utility modelly several the sail post is provided with sail, the installation direction of the left and right sides is just in time opposite in the every pair of sail, when a side flows the front for meeting water, opposite side just in time is the stream reverse side that meets water, the positive sail lifting surface area of stream that meets water is big, meet water stream reverse side the sail lifting surface area little, so when the water impact sail, positive sail is stressed big, the sail of reverse side is stressed little, and these two power act on the transmission shaft simultaneously by the sail post, makes transmission shaft along the big side rotation of power, the rotation axle driven dynamo of rotation, thus reached the purpose of generating electricity.

Description of drawings

Concrete structure of the present utility model is by providing in following examples and the accompanying drawing.

Fig. 1 is the utility model embodiment 1 overall structure schematic representation.

Fig. 2 is the utility model embodiment 1 sail schematic representation.

Fig. 3 is the utility model embodiment 2 sail schematic representation.

Embodiment

Further describe the utility model below in conjunction with accompanying drawing, with the platform (2) anchor (9) and the anchor chain (8) that float on the surface, anchoring has the place of tidal flow in the sea, every 90 ° checking bollard (3) is set on the platform edges and is used to cleat and anchor chain, with fixed platform.Be installed in the generator (1) on the platform, the transmission shaft (4) of connection generator, per 60 ° three pairs of sail posts (7) are installed regularly around the lower end of transmission shaft, three pairs of sails (6) are installed on the sail post separately, sail (6) is just in time opposite with sail 6 ' installation direction, when sail 6 ' flows the front for meeting water, sail 6 just in time is the stream reverse side (as Fig. 1) that meets water, and the installation situation of two pairs of sails is identical with last a pair of sail in addition.Because of the curved web plate shape of the sail of present embodiment 1 (11) (Fig. 1, Fig. 2) be installed in the substantially horizontal front portion of sail post, the grid framework concave surface is the flow path direction that meets water, a synthetic fiber cloth (5) (as Fig. 2) that can cover grid framework is being fixed in the top of framework concave surface, when the concave surface of sail bent frame meets water stream, synthetic fiber cloth (5) is blocked by grid framework, be subjected to the limit area big, Driving force is big, and opposite side sail convex surface meets water when flowing, and the synthetic fiber cloth side is started several angle by the current impulsion, and is maximum parallel to horizontal plane, current flow through from grid framework, love power area is little, and resistance is little, and transmission shaft (4) will rotate (Fig. 1 state) down along the effect of power general orientation.After 60 ° of transmission shaft (4) rotations, another effect to sail is just in time exchanged with sail 6 and 6 ', being still sail is subjected to the big side of impact force of water flow to promote the transmission shaft clockwise direction again to rotate, when 180 ° of changes of direction of tidal flow, stressed big sail just in time with the changing of opposite side, but transmission shaft still rotates by former clockwise direction.(when the installation direction of two side sails was changed about having only, the transmission shaft direction just can rotate counterclockwise), thus the generator on the rotating drive shafts driving platform reaches the purpose of generating.

Embodiment 2 is tubaeform sail, and this sail is fixed in the front portion of the horizontal aspect of sail post, and (12) are frontal, and (13) are the reverse side direction, (as Fig. 3), and when the sail front met water stream, resistance was bigger, and is stressed big; And opposite side sail reverse side meets water when flowing simultaneously, and water resistance can reduce greatly, and is stressed little, and these two power act on the transmission shaft simultaneously by the sail post, and transmission shaft will rotate along the big direction of power.

Implement

1,2 in order from current, to obtain energy as much as possible, enlarge the lifting surface area of sail on the one hand, utilize lever principle on the other hand, increase the length of sail post, sail post and sail frame are made hollow, make it produce suitable buoyancy, can suspend in the water, so just can alleviate the stressed of platform, front end at each sail post connects with cable wire, just can improve the stressing conditions of each sail post, along with the lifting surface area increase of sail and the growth of sail post, the energy that offers generator also will correspondingly increase, and builds large-scale stream generating device like this and just can realize.

The beneficial effects of the utility model are: can utilize the energy of natural flows to produce bigger The TRT of power just can be set up a plurality of large-scale power generation region in the China coast marine site, and And do not consume the energy, can be to environment, simple in structure.
