Description

A kind of wind generating unit

Technical field

The utility model relates to technical field of wind power generation, particularly relates to a kind of wind generating unit.

Background technique

In recent years, along with the fast development of society's industry, the demand of the mankind to the energy is increasing, and due to traditional energy, such as coal, oil, rock gas are non-renewable energy resources, and what therefore energy problem became is growing tension; Find the new energy, to human development, there is very important effect.

As everyone knows, wind-power electricity generation is that the kinetic energy of keeping watch transfers electric energy to.Wind energy, as a kind of clean renewable energy sources, is more and more subject to the attention of countries in the world.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 × 10^9MW, and wherein available wind energy is 2 × 10^7MW, than the water energy total amount that the earth can develop also large 10 times.Wind is utilized by people very early--mainly to be drawn water by windmill, flour milling etc., and now, people are interested is how to utilize wind to generate electricity.THE WIND ENERGY RESOURCES IN CHINA is enriched, the wind energy content that can develop about 1,000,000,000 kW, wherein, land wind energy content about 2.53 hundred million kW (land is liftoff 10m height material computation), marine can wind energy content about 7.5 hundred million kW of development and utilization, amount to 1,000,000,000 kW.And whole nation electric power installation in the end of the year 2003 about 5.67 hundred million kW.Wind is one of energy not having public hazards.And it is inexhaustible.For lack of water, short bunker and ungetable offshore islands, Pastoral Areas, mountain area and area, plateau, utilize wind-power electricity generation with suiting measures to local conditions, very applicable, be well worth doing.

Found by long-term practice: wind-driven generator mainly relies on wind-force to realize generating, therefore, it is spacious more local than more rich that wind-driven generator generally needs to be based upon wind energy resources, generally, the place that this wind energy is more abundant, its environmental conditions is relatively more severe, and therefore the generation of the extreme weather such as hurricane or cloudburst often can occur; And once there is above-mentioned extreme weather; wind-driven generator often can be caused to break down; simultaneously; wind-driven generator also needs regularly to carry out maintenance test; but because the pole of wind-driven generator is general higher; overhaul so engineer needs to adopt aerial ladder to ascend a height, maintenance process is very inconvenient, therefore designs and develops a kind of wind generating unit being convenient to maintenance conditions and seems it is particularly important.

Model utility content

The technical problems to be solved in the utility model is: provide a kind of wind generating unit.The pole of this wind generating unit can freely be elevated, and then is convenient to the maintenance of engineer.

The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:

A kind of wind generating unit, comprises columniform pole (1) and is fixed on the wind-driven generator (2) at support (1) top; It is characterized in that: at least also comprise:

For installing the supporting frame (4) of pole (1), support frame as described above (4) is fixed on ground, offer at the upper surface of support frame as described above (4) through hole that pole (1) passes, between the inwall and pole (1) of described through hole, sheath (3) is installed;

For controlling the cylinder (5) of pole (1) in the vertical direction motion, the piston rod of described cylinder (5) is fixedly connected with the lower end surface of pole (1).

Further: support frame as described above (4) is made for stainless steel material.

The advantage that the utility model has and good effect are:

By adopting technique scheme, pole in the utility model, under the active force of cylinder, can freely be elevated, therefore the unnecessary ascend operation of maintenance conditions engineer, so improve the efficiency of maintenance conditions, avoid the stealth danger that high-lift operation brings to engineer simultaneously.

Accompanying drawing illustrates:

Fig. 1 is the structural representation of the utility model preferred embodiment.

Wherein: 1, pole; 2, wind-driven generator; 3, sheath; 4, supporting frame; 5, cylinder.

Embodiment

For model utility content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1, a kind of wind generating unit, comprise columniform pole 1, be fixed on support 1 top wind-driven generator 2, for install pole 1 supporting frame 4, for control pole 1 in the vertical direction motion cylinder 5; Support frame as described above 4 is fixed on ground, offers the through hole that pole 1 passes, between the inwall and pole 1 of described through hole, be provided with sheath 3 at the upper surface of support frame as described above 4; The piston rod of described cylinder 5 is fixedly connected with the lower end surface of pole 1.

Working principle of the present utility model is: when engineer needs to carry out periodical repair or troubleshooting to wind-driven generator, cylinder 5 can be utilized to drive pole 1 to decline, and engineer only needs the upper surface standing on supporting frame 4 can complete maintenance or maintenance work subsequently;

Further: because wind-driven generator works in the wild, therefore get rusty to prevent, support frame as described above 4 is made for stainless steel material.

Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.

Claims (2)

1. a wind generating unit, comprises columniform pole (1) and is fixed on the wind-driven generator (2) at support (1) top; It is characterized in that: at least also comprise:

For installing the supporting frame (4) of pole (1), support frame as described above (4) is fixed on ground, offer at the upper surface of support frame as described above (4) through hole that pole (1) passes, between the inwall and pole (1) of described through hole, sheath (3) is installed;
