Description
Technical field:
The utility model relates to a kind of solar energy control device, is specifically related to a kind of slot type concentrating collector follow-up mechanism.
Background technology:
More original solar energy heat collectors, as solar water heater, its solar heat-collection plate all is a fixed structure, can not adapt to the sun and rise the characteristics of motion that the dusk falls to the west from east morning, it is short to receive the sunshine vertical irradiation time, and solar energy heating is few, and the latitude of saying nothing of winter and sun direct projection in summer is inconsistent, therefore, one of technology that improves solar energy heating efficient most critical is exactly the problem that solves the irradiation of sun-tracing light straight line.
Summary of the invention:
Technical problem to be solved in the utility model is: solve existing solar energy heat collector and be stationary structure, can not sun-tracing light vertical irradiation, problem that collecting efficiency is low, and provide a kind of simple and practical, sun-tracing light vertical irradiation, focusing heat collection effective, greatly improve the slot type concentrating collector follow-up mechanism of solar energy efficient.
The technical solution adopted in the utility model is: fixing parabolic lens panel and be located at the thermal-collecting tube at parabolic minute surface focus place on girder, girder is bearing on the column by rotating shaft, bearing block connection, fixedly connected with sector gear in the girder termination, stepper motor is by decelerator output pinion and sector gear engagement, the both sides of column are equipped with travel switch, and stepper motor is connected with computer control circuit with travel switch.
The utility model can make the slot type concentrating collector rotate around an axle, geographical position and the angle and the local time of putting according to concentrating collector, the control circuit micro computer calculates the angle that heat collector rotates all the time, and send pulse signal and give stepper motor, stepper motor passes through decelerator, pinion, sector gear, girder transmission heat collector, follow the tracks of the sun from the east orientation west or in short transverse, make sunray be focused on the thermal-collecting tube all the time, greatly improved the efficient of solar facilities, solved traditional solar thermal collector stationary structure, the sunshine vertical irradiation time is short, a little less than the intensity of illumination, the technical barrier that collecting efficiency is low, the utility model can from morning to night be followed the tracks of solar irradiation, it is vertical with solar irradiation that the parabolic minute surface is remained, and absorbs solar energy efficient height.In addition, the slot type concentrating collector structure of the utility model design also has outstanding feature, according to optical principle, the collimated light beam of solar radiation is mapped on the throwing face minute surface and is reflected, focuses on the focal line, so just can improve radiant energy density on the unit are, after focusing on tens times solar radiations on the thermal-collecting tube, the heat source water in the thermal-collecting tube just can be heated to high temperature, and keeps higher thermal efficient.The utility model is installed in thermal-arrest plate below with stepper motor, decelerator, pinion, driving the thermal-arrest plate with sector gear rotates, can reduce the distance between the thermal-arrest plate like this, improve the utilization rate of the solar radiation that is focused, also just improve the collecting efficiency of collecting system.The utility model adopts big retarding than 1: 500, so the stepper motor that only needs 140 watts can drive 5 thermal-arrest plates and rotate, 65 square metres of 5 thermal-arrest plate collector areas, and the thermal-arrest plate fresh gale with interior guarantee tracking accuracy at 0.3 ° with interior operate as normal.The utility model is commercial design, and is simple in structure, long service life, and it is very convenient to install.
