Description
Technical field
The utility model relates to a kind of sunshine tracking system of groove type solar gathering-device, belongs to field of solar thermal power generation.
Background technology
The groove type solar gathering-device divides two kinds of a kind of fixed sunlight collecting faces, and such harvester is easy for installation simple in structure.But can't rotate along with sun's motion, utilization factor is not high.Second kind is movable, can be according to the rotated position collection surface of the sun.This device needs manual work to go calibration accuracy not high at present, and cost is bigger.
The utility model content
The utility model provides a kind of sunshine tracking system of groove type solar gathering-device to above-mentioned deficiency.
The utility model adopts following technical scheme:
The sunshine tracking system of the described groove type solar gathering-device of the utility model, comprising can rotating groove type solar gathering-device support, also comprises photoelectric encoder, Hydraulic Station, PLC controller, supervisory control comuter; Described photoelectric encoder is arranged on the revolving shaft of rotating groove type solar gathering-device support; Photoelectric encoder is connected with the input end of PLC controller; The hydraulic pressure output terminal of Hydraulic Station links to each other with oil cylinder on the groove type solar gathering-device support, the PLC controller also respectively with Hydraulic Station, supervisory control comuter is two-way is connected.
Beneficial effect
The sunshine tracking system of the groove type solar gathering-device that the utility model provides; Utilize the preset angle that needs conversion of reserving of photoelectric encoder; Time and angle through its conversion of PLC controller control; It is accurate that the hydraulic pressure shop helps the cylinder rotation to reach angle, and supervisory control comuter is monitored its rotation work process automatically, and is time saving and energy saving.
Description of drawings
Fig. 1 is the structural representation of the utility model;
1 is groove type solar gathering-device support among the figure, the 2nd, and photoelectric encoder.
Embodiment
Below in conjunction with accompanying drawing to the utility model further explain:
As shown in the figure: the sunshine tracking system of groove type solar gathering-device, comprising can rotating groove type solar gathering-device support 1, photoelectric encoder 2, Hydraulic Station, PLC controller, supervisory control comuter; Described photoelectric encoder 2 is arranged on the revolving shaft of rotating groove type solar gathering-device support 1; Photoelectric encoder 2 is connected with the input end of PLC controller; The hydraulic pressure output terminal of Hydraulic Station links to each other with oil cylinder on the groove type solar gathering-device support 1, the PLC controller also respectively with Hydraulic Station, supervisory control comuter is two-way is connected.
According to parameters such as the geography of locality, meteorology, times; Calculate real-time sunray incident angle (elevation angle and position angle); And then, calculate the reflecting surface spool of sening as an envoy to and aim at the required angle of revolution of solar incident ray according to the geometric position (absolute angle sensor) of slot type receiving system reflecting surface normal relative ground normal and axis of rotation; Drive reflecting surface wraparound rotating shaft rotation through PLC control hydraulic jack, make the reflecting surface normal aim at sunray, thereby realize the real-time solar tracking of slot type system.
Angle of incident light calculates and is undertaken by the monitoring software that is installed in the supervisory control comuter, sends to PLC through serial line interface, and system's real-time running state feeds back to supervisory control comuter by PLC.The position probing of slew gear is realized that by photoelectric encoder PLC regulates computing according to angle on target and actual angle, gives the ratio adjusting valve output control signal of Hydraulic Station, and then the motion of driving oil cylinder.Photoelectric encoder angular detection precision (resolution): 0.05 degree, Position Tracking Control precision: ± 0.05 degree, monitoring software function: networking time service function, systematic parameter set-up function.
Tracking control system is simple in structure, and stable and reliable operation does not receive the influence of weather condition.
Easy to operate, the friendly interface of monitoring software.
Two kinds of tracking modes:
1, supervisory control comuter is connected with PLC all the time, monitors in real time.Computing machine each hour and network time service center to the time once, and calculate sun angle in real time, slot type reflecting surface normal target position data is sent to PLC, carry out the precise real-time tracking Control by PLC.
2, can be according to demand; Supervisory control comuter calculates the position of sun angle-data table of a day (10 hours) by certain time interval; Be directly downloaded among the PLC; Can by PLC according to its internal clocking (every day must through network to the time once) and tables of data inquire about close time point reflecting surface normal target location, the row interpolation of going forward side by side draws real-time reflecting surface normal target location, and then carries out tracking Control.
The modified value of local longitude, latitude, sea level elevation, average temperature of the whole year, annual atmospheric pressure, Coordinated Universal Time(UTC) and atomic time.Wherein the modified value of Coordinated Universal Time(UTC) and atomic time is obtained from country's bulletin of time service unit, and correction in general a year once gets final product.
