Problems solved by technology

[0004] my country has started research on solar tracking systems since 1990. So far, there have been certain research results in China, and these research results have been put into use in actual solar power plant projects, but the cost of these solar tracking systems is quite high, and If the power consumed by the tracking system is included, the power generation income of the power station after the tracking system is not increased compared with the power generation income of the fixed solar panel, so the tracking system of many power stations in the northwest is shut down, which is to some extent caused a lot of waste

Embodiment 1

[0045] Embodiment 1: as figure 1 As shown, the ecliptic tracker is composed of a support, a polar axis transmission mechanism, a pitch axis transmission mechanism, a solar cell panel support structure, electrical facilities and a solar cell panel 21 . The support includes base plate 1, stiffener 2, steel pipe column 3, and column end plate 4. The base plate 1 is connected to the underground foundation through anchor bolts, the steel pipe column 3 is welded to the base plate 1, and the stiffener 2 is welded at the node to strengthen the node of the column foot , The column end plate 4 is welded on the top of the steel pipe column 3 . The polar shaft transmission mechanism includes a pitch shaft 5, a worm gear motor unit support plate 6, a worm gear motor unit 7, a pole shaft 14, and a slider 13. The worm gear motor unit support plate 6 is hingedly connected to the column end plate 4 through the pitch shaft, and the worm gear The worm motor unit 7 is mounted on the worm gear mo...

Embodiment 2

[0058] Embodiment 2: as figure 2 Shown is the second embodiment of the present invention, which adopts the hand wheel 905 instead of the second stepping motor 901 to adjust the worm gear screw lifter 9. This embodiment can be used in the case where the cost control of the tracker is relatively low Next, when installing the new ecliptic tracker, adjust the pitch angle of the solar panel 21 by turning the hand wheel 905 to make it the same as the local latitude angle, and then lock the hand wheel 905 to fix the pitch angle. In this way, when the tracker performs daily visual movement, it is equivalent to only the polar axis 14 rotating, which becomes a typical single-axis tracking system. The advantages of this embodiment are that the cost is relatively low, the control system is relatively simple, and the adjustment of the pitch angle is convenient and precise. In addition, after the tracker is discarded in one place, it can be recycled and installed in another place, and the...

Embodiment 3

[0059] Embodiment 3: as image 3 Shown is the third embodiment of the present invention, the polar axis on the tracker is connected to the parabolic cylinder support truss 23, and the parabolic cylinder support truss 23 is covered with a parabolic cylinder reflector panel 22, while the parabolic cylinder support truss 23 The upper frame is provided with a double-effect concentrated solar clarinet 24, and the tracker is used in conjunction with the double-effect concentrated solar black pipe 24, so that the power generation efficiency of the double-effect concentrated solar black pipe 24 is further improved.

The novel ecliptic tracker for the solar energy comprises supports, a polar axis transmission mechanism, a pitch axis transmission mechanism, a solar cell panel supporting structure and electric facilities, wherein each support comprises a bottom plate, a stiffening rib, a steel pipe column and a column end plate; the polar axis transmission mechanism comprises a pitch axis, a worm and gear motor set supporting plate, a worm and gear motor set, a polar axis and the like; the pitch axis transmission mechanism comprises a pitch axis, a worm wheel screw rod elevator supporting plate, a worm wheel screw rod elevator, a screw rod connecting end plate, a sliding block rotating shaft, a sliding block end plate and the like; the solar cell panel supporting structure comprises a circular pipe beam node plate and supporting angle steel; the electric facilities comprise stepping motors, a photoelectric sensor set and an MCU controller box. The novel ecliptic tracker for the solar energy resolves the contradiction between tracking precision and manufacturing operating cost through an ecliptic tracking technique, a tracker structural system and a bidirectional strategy automatic control system. The novel ecliptic tracker for the solar energy has the advantages of being low in cost, easy to produce in bulk, convenient to install on site and reliable in operation, saving energy and the like. The novel ecliptic tracker can be widely applied to the application fields of solar energy slot type optical collector power generation and solar photovoltaic power generation.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization and application, and in particular relates to a new type of automatic tracking device for solar energy, in particular to a new type of ecliptic tracker for solar energy using ecliptic tracking technology. Background technique [0002] As a sustainable and clean energy source, solar energy is an ideal renewable energy source. Due to the vast land area of ​​our country, the solar energy resources are quite rich, and its distribution range is wide, the annual radiation of more than 2 / 3 of the country is greater than 5020MJ / m 2 , the number of annual sunshine is above 2000h, therefore, the development potential of solar power generation in our country is huge. [0003] At present, the main factors restricting the development of solar power generation industry are the high cost of photoelectric conversion, large fluctuations in power generation and unsuitability for long-distance tran...
