Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 1, 2, the present invention's two dimension automatic sun tracing trough type solar heat-collector, there is body supports 2, transmission system 4, condenser bracing frame 1 and thermal-collecting tube 3, wherein body supports 2 is as the support of whole heat collector, it is provided with condenser bracing frame 1 and transmission system 4, thermal-collecting tube 3 is connected with condenser bracing frame 1 by collector tube holder; Transmission system 4 has the two pairs of motor and speed reducers be arranged in body supports; The control system of solar thermal collector is arranged in body supports, and photosensitive sensor is arranged on condenser bracing frame, and links with condenser bracing frame; The output of two pairs of motor and speed reducers connects the rotation transmission device of condenser bracing frame 1 level and vertical both direction respectively.
Body supports 2 is the support component of whole heat collector, and condenser bracing frame 1, transmission system 4 and thermal-collecting tube 3 are all supported by it.The transmission agency of transmission system 4 is realized jointly by photosensitive sensor, control system and the two pairs of motor and speed reducers be arranged in body supports 2, photosensitive sensor follows the tracks of solar azimuth according to sunshine hard real time, and by signal transmission to control system, controlled motor by control system, two pairs of motor and speed reducers are respectively the rotating torque that condenser bracing frame 1 provides level and vertical both direction again.Condenser bracing frame 1 is the general frame structure be made after the operation such as stretch bending, welding by multiple rectangle hollow pipe, and it is symmetrical relative to body supports.Condenser installation seat plate is welded on the rectangle hollow pipe of condenser bracing frame 1, the position one_to_one corresponding of it and parabolic concentrator back side ceramics seat, the positional precision of condenser installation seat plate determines the overall surface accuracy of parabolic reflector, and then affects the spotlight effect of whole equipment.Thermal-collecting tube 3 is connected by collector tube holder and condenser bracing frame 1, and thermal-collecting tube 3 center should be equal with parabolical focal length value to the distance of parabolic reflector.
Transmission system adopts low-power machine to drive the power combination of worm-gear speed reducer, for two rotating shafts provide flywheel moment, control the left and right adjustment of condenser bracing frame 1 in the horizontal direction, the angle of pitch adjustment of condenser bracing frame 1 is controlled at vertical direction, substitute traditional hydraulic workstation system, more simple in structure, functionally more easily realize.Adopt rectangular tube stretch bending process to make condenser bracing frame, structure is simple, lightweight.
The present invention is for 8 parabolic reflectors, and sunshine vertical irradiation is on 8 parabolic reflectors, and light focuses on after reflection on thermal-collecting tube, and forms the light belt that has one fixed width.Because sun altitude constantly changes in time, parabolic reflector, under the control of automatic sun tracing device, constantly in horizontal or vertical direction adjustment angle, and keeps vertical with sunshine all the time.The light belt focused on thermal-collecting tube will manage interior heat-conducting medium heating, and heat-conducting medium absorbs the heat of condenser reverberation, and is carried by pipe-line system, be passed to terminal by heat, thus realizes transmission and the conversion of energy.
The physical dimension different according to condenser bracing frame, the parabolic reflector that there is plurality of specifications and quantity can match, and refers to shown in Fig. 3, Fig. 4, Fig. 5, is respectively 4,16 48 parabolic reflectors.
