Description

Gear type swing solar bracket

Technical field

The utility model relates to solar power plant, relates in particular to a kind of gear type swing solar bracket of effectively sun-tracing light.

Background technology

Along with the raising of science and technology, clean energy resource has obtained development faster.Particularly solar energy is being widely used aspect heat supply heating of traffic signals, traffic lighting, the power supply of island communication base station and people's life or the like.The photovoltaic panel of solar facilities adopts support it to be propped up and towards the sun usually, it is multiple spot sensitization or large tracts of land sensitization that the light of traditional solar bracket that apply the existing market is followed the trail of, the defective of this tracking sensitization is that the stability of a system is poor, fall on the solar panel a last fly or near put fireworks, all can cause the reflection error of vapour sensing element.Be that interference free performance is poor, at the bottom of the precision of system keeps track, poor to the adaptedness of weather.

Summary of the invention

The utility model is at the bottom of the precision that solves poor stability that solar bracket light follows the trail of, system keeps track and to the technical problem of the adaptedness difference of weather, the precision height that provides a kind of light to follow the tracks of, antijamming capability is stronger, and stability is gear type swing solar bracket better.

For solving the problems of the technologies described above, the technical solution of the utility model is a kind of gear type of a structure swing solar bracket, and it comprises: hollow column, be set in back shaft in this hollow column, be connected in this back shaft of driving on hollow column and the back shaft around first drive unit of self rotational, laterally be located at back shaft top the solar panel rotating shaft, be connected in this solar panel rotating shaft of driving in back shaft and the solar panel rotating shaft around second drive unit of self axis swing, the solar panel that is connected with the solar panel rotating shaft.

First connecting plate of the support orientation drive motors that preferred version of the present utility model, described first drive unit comprise first sector gear be located on the back shaft, first worm screw with this sector gear engagement, the orientation drive motors that is connected with this first worm screw, be connected with hollow column.

Described second drive unit comprise second sector gear that is connected in the solar panel rotating shaft, with second connecting plate of second worm screw, the level inclination motor that is connected with this second worm screw, the support worm screw that is connected with back shaft and the fixing horizontal inclination angle motor of this sector gear engagement.

The periphery of described hollow column and back shaft also is provided with a sleeve.

Employing of the present utility model two cover drive units make solar panel not only can swing around vertical axes, but also can swing around lateral shaft.It is the controlled all the time driving of solar panel, follow the tracks of running track from sun, cell panel is on the best shadow surface all the time, per day illumination improves 200 watts/square metre than existing traditional follow-up mechanism, prolong 2～4 hours assembly time for exposure, improve photoelectric conversion efficiency 20%-40%.Compare with existing photovoltaic tracker, the precision height that its advantage is to follow the trail of (＜0.05 degree), strong, the good stability of antijamming capability, and have automatic recognition function.With present technology, domestic photovoltaic generation equipment input is on average more than 70 yuan/watt, and wherein demonstration power station, the state-of-the-art desert of technology cost is more than 60 yuan/watt, and every kilowatt equipment input is 70,000 yuan, and the electric cost of every degree is a 2.7-3 unit; The utility model makes cost reduce to 48 yuan/watt significantly, and every kilowatt equipment input is 4.8 ten thousand yuan, and the electric cost of every degree is a 1.63-1.97 unit.Solved anti-interference problem fully, the precision of system keeps track is higher, and stability is better, and is also higher to the adaptedness of weather.
