A servo motor 1 is installed on the motor support 1 and can be adjusted forward and backward. A motor gear 1 is installed on the servo motor 1 and can be adjusted up and down. A tooth rotating disc is installed on a fixing stand pillar and meshed with the motor gear 1. The servo motor 1 drives the motor gear 1 to rotate around the tooth rotating disc, thereby driving the rotating stand pillar and the fixing stand pillar to mutually rotate, and enables a rotary table to rotate. A reflector installing frame rotates with the rotary table, and therefore azimuth angles in east and west directions are changed. A servo motor 2 is installed on a motor support 2, and the servo motor 2 and the motor support 2 are installed in the rotary table. A main shaft is a gear shaft with a gear, wherein a motor gear 2 is meshed with the gear on the main shaft, the servo motor 2 drives the motor gear 2 to rotate and drives the main shaft to rotate, the main shaft is installed on the rotary table, the reflector is installed on the main shaft, and a bearing which can flexibly rotate is installed between the rotary table and the main shaft, and accordingly azimuth angles in north and south directions of the reflector can be changed.
Description
Technical field
The present invention relates to a kind of sunshine double-axis tracking catoptron.
Background technology
Because China mountain region is numerous, in order to shorten the traffic mileage, improve transport benefits, save land used and keep ecologic environment, more and more pay attention to tunnel construction in transport development.The requisite technology of tunnel construction is tunnel illumination, no matter and daytime or night tunnel illumination all very important, and daytime, lighting problem was more complicated than night.Tunnel illumination requires energy savings, improves illuminating effect, guarantees travel safety and comfortableness on communications and transportation unimpeded safe basis guaranteeing.
The present whole nation is built and reached more than several thousand kilometers at built tunnel, and with very fast speed development.But the considerably less of illuminator installed in the tunnel, illumination mostly is not set or illuminator is set not use, so lighting quality is very low.The development of China tunnel illumination light fixture is started late, and foundation is weak, the particularly further investigation for tunnel illumination characteristic aspect extremely lack, with the larger gap of external existence.
Can be found out by above present situation, design a kind of sunshine double-axis tracking reflector apparatus, make it to be applied to tunnel illuminating system, the utilization of promotion sunshine that can be favourable effectively solves the problem of tunnel illumination.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of sunshine double-axis tracking catoptron, with gear teeth disc mechanism driving horizontal revolving stage rotation adjustment East and West direction position angle, control the main shaft north-south angle of pitch with servomotor gear drive gear shaft aligning elevation gear, simple in structure, flexible movements.
To achieve these goals, the technical solution used in the present invention is:
A kind of sunshine double-axis tracking catoptron comprises:
Horizontal adjusting mechanism, electric machine support 1 is welded on Rotary cloumn 12, servomotor 1 is arranged on electric machine support 1 and can adjusts front and back, motor gear 1 is arranged on servomotor 1 and can adjusts up and down, turning fluted disc 11 is arranged on vertical columns 12 and motor gear one 1 interlocks, fluted disc 11 rotation that rotates of servomotor one 3 drive motor gears 1, thereby driving Rotary cloumn 4 and vertical columns 12 rotates mutually, cause turntable 6 to rotate, penetrate on mirror 10 installation frames 15 and rotate with turntable 6, thereby change is at the position angle of east-west direction;
Aligning elevation gear, servomotor 28 are arranged on electric machine support 29, and servomotor 28 and electric machine support 29 are arranged in turntable 6; Main shaft 5 is one and is with cogged gear shaft, engaged gears on motor gear 27 and main shaft 5, servomotor 28 drive motor gear 27 rotations, thereby drive shaft 5 is rotated, main shaft 5 is arranged on turntable 6, catoptron 10 is arranged on main shaft 4, and bearing 11 is housed between turntable 6 and main shaft 4 can flexible rotating, thereby changes catoptron 10 at the position angle of North and South direction.
Catoptron 10 is the arbitrary shapes such as rectangle or circle.
The present invention rationally arranges the rotating speed of servomotor by precalculated data, continues the rotation of drive shaft, turntable, thereby changes the angle of catoptron, guarantees solar reflection optical line orientation and level constantly.
The invention discloses a kind of sunshine double-axis tracking catoptron, can be used as a critical component of sunshine tunnel illuminating system, sunshine is reflexed to required position, then match with other mechanisms sunshine is reflexed in the tunnel, thereby realize tunnel illumination.
The present invention can be made into catoptron rectangle, circular arbitrary shape as required, and convenient the installation can be by wide popularization and application.And because principle is similar, the present invention can with the sunshine orienting reflex, therefore also can be used for the tower type solar electricity generation system.
