Description
Technical field
The utility model relates to a kind of novel hydraulic drive unit, particularly relates to torque tube fluid pressure drive device.
Background technology
Along with utilizing the hope of solar energy heat-obtaining to ask gradually strong, there is system stability, the solar groove type heat collector of workable advantage becomes first-selection.Solar groove type thermal-arrest be with parabolic mirror by solar light focusing on the thermal-collecting tube be positioned on parabola focal line, working media capable of circulation is housed in thermal-collecting tube, and working media again heating water driving steam turbine generates electricity.In order to improve the thermal efficiency, will improve parabolic mirror reflects rate, improving the surface precision of parabola glass, and ensureing that groove type heat collector will accurately follow the tracks of the sun, this just needs to drive speculum to rotate to trace location accurately.
But existing type of drive exists certain shortcoming: one, most employing common electric machine chain, need reductor, need intermediate transmission, the anglec of rotation of bad control torque pipe, is unfavorable for accurate tracking; Two, a part adopts light sensor as the driving control system of collection signal, and tracking accuracy is not high, and system cloud gray model is unstable.
Utility model content
The purpose of this utility model is the deficiency overcoming existing type of drive, a kind of torque tube fluid pressure drive device for trough heat collection is provided, controlling two hydraulic cylinders by control system drives speculum to rotate to the position of tracking, this drive unit adopts hydraulic pressure as power, cost is lower, and power performance is good.
Torque tube fluid pressure drive device, comprises the first speculum, the second speculum, torque tube, hydraulic cylinder, accumulator, pumping plant, CPU, obliquity sensor, data storage.
Described first speculum and torque tube level connection joint, torque tube and the second speculum level connection joint, torque tube is vertically connected with hydraulic cylinder, hydraulic cylinder is connected with pumping plant with accumulator, pumping plant is connected with CPU, CPU is connected with data storage respectively with obliquity sensor, and obliquity sensor is connected with the second speculum.
In the technical solution of the utility model, when the second mirror angle deflection, obliquity sensor can receive signal and be transferred to CPU, the theoretic angular deflection value of frame for movement calculated according to astronomical algorithm stored in this deflection angle and data storage compares by CPU, when there is deviation in two angles, CPU can launch pulse signal, and by this pulse signal transmission to pumping plant, pumping plant drives hydraulic cylinder, hydraulic cylinder driving torque pipe rotates, and then drive the first speculum to rotate, to revise the angular deflection of the second speculum.This drive unit adopts hydraulic pressure as power, cost is lower, power performance is good, hydraulic drive is easy, the flow that can carry out hydraulic control pump by electrical system regulates the speed of hydraulic cylinder extension, eliminate the traditional transmission modes such as common electric machine chain and need reductor, need the shortcoming of intermediate transmission.
