Abstract
The utility model relates to a water current electric generator. The water current electric generator is characterized by comprising a floating body which floats on a water surface, a draft tube which is arranged underwater and fixedly connected with the floating body, a rotating shaft which is arranged in the draft tube and extends in the axial direction of the draft tube, rotary blades which are distributed on the rotating shaft in a circumferential mode, and a generator body which is arranged on the floating body and is in transmission connection with the rotating shaft. According to the water current electric generator, the rotary blades are driven by water currents to rotate, the rotating shaft is driven to rotate at the same time, then, the rotating shaft drives the generator body to rotate through a transmission mechanism so as to convert the gravitational potential energy of the water currents into mechanical energy, and then the mechanical energy drives the generator body to output electric power. The water current electric generator is simple in structure, low in manufacturing cost, wide in application range, and quite suitable for power generation through brooks and rivers in the countryside, and therefore some small water resources can be utilized.
Description
Technical field
The utility model relates to a kind of water flow generator.
Background technique
The basic principle of generating power by water current is to utilize the height of water, and the potential energy of water is converted into to mechanical energy, then with the mechanical energy pushing generator, and obtain electric power.Scientists, with the natural endowment of this height of water, is effectively utilized stream power engineering and mechanical-physical etc., and collocation is to reach the highest generated energy meticulously, and cheapness for people to use is free of contamination electric power again.And low level water carries out water circulation and is distributed in the earth everywhere by absorbing sunlight, thereby reply high-level water source.
Water power is a kind of clean reproducible energy, but the utilization of water power at present is mainly by building dam, builds the dam engineering investment greatly, and cost is high, and is only applicable to large-scale river region, also can affect to local environment simultaneously.
The model utility content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of generating efficiency high, applied widely, and water flow generator simple in structure, with low cost.
The utility model adopts following technological scheme: a kind of water flow generator is provided, it is characterized in that: comprise buoyancy aid on bubbling through the water column, be arranged at the guide shell that is fixedly connected with buoyancy aid under water, be arranged in guide shell along the axially extended rotating shaft of guide shell, circle distribution the rotation blade in rotating shaft and be arranged at the generator be connected with rotating shaft transmission on buoyancy aid.
Preferably, described buoyancy aid comprises two hulls on bubbling through the water column and the connecting plate that connects two hulls, and described hull is connected with the ship anchor be sunken under water.
Preferably, described generator is connected by driving mechanism with rotating shaft, this driving mechanism comprise the first belt pulley of being arranged in rotating shaft, be arranged at the second belt pulley on generator and be tensioned to the first belt pulley and the second belt pulley between belt.
Preferably, the water intake of described guide shell is provided with trumpet-shaped drainage hood.
From above-mentioned, to description of the present utility model, compared with prior art, the obtainable beneficial effect of the utility model is:
(1) rotation blade rotates under the driving of current, drives rotating shaft simultaneously and rotates, and rotating shaft drives generator to rotate by driving mechanism again, thereby the gravitational potential energy of current is converted into to mechanical energy, then with the mechanical energy pushing generator, and output power.The utility model is simple in structure, and low cost of manufacture, and applied range are highly suitable for the brook river generating of country, and some little water resources are utilized.
(2) by the ship anchor, buoyancy aid is fixed, guide shell is also thereupon fixing, can, along with current float and rotate, not guarantee generating efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1 guide shell.
Embodiment
Below by embodiment, the utility model will be further described.
As shown in Figure 1 and Figure 2, a kind of water flow generator described in the utility model, comprise hull 1, connecting plate 2, guide shell 3, rotating shaft 4, rotation blade 5 and generator 6.
Hull 1 floats on the surface, and is fixedly connected with connecting plate 2 between hull 1, makes it form a larger buoyancy aid of area.Hull 1 is connected with the ship anchor 11 be sunken under water, makes it swim in position waterborne and can keep fixing.
Guide shell 3 is arranged under water, and it is fixedly connected with connecting plate 2 by connecting rod 31, and is positioned at connecting plate 2 belows.The water intake of guide shell 3 is provided with trumpet-shaped drainage hood 32, plays the effect of drainage, increases the unit time by the water flow of guide shell 3, to improve generating efficiency.
Rotating shaft 4 is arranged in guide shell 3, and it extends axially along guide shell 3.Rotation blade 5 circle distribution are in rotating shaft 4.
The utility model is arranged on the place of current, current enter guide shell 3 by drainage hood 32, rotation blade 5 rotates under the driving of current, drive rotating shaft 4 rotates simultaneously, rotating shaft 4 drives generator 6 to rotate by driving mechanism again, thereby the gravitational potential energy of current is converted into to mechanical energy, then with mechanical energy pushing generator 6, last output power.
Above are only an embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
