Problems solved by technology

But it has two disadvantages. First, the stepping mechanism that tracks the pitching motion of the sun is superimposed on the semicircular orbit mechanism, and rotates around the polar axis with the semicircular orbit mechanism. The driving error brought by the semicircular orbit mechanism will be accumulated on the stepping mechanism. , there is a tracking cumulative error; second, the quality of the pitch drive device is borne by the azimuth drive device, resulting in a large load on the end drive

Embodiment 1

[0033] Embodiment 1: The reflector of this embodiment adopts a bias feeding structure.

[0034] refer to figure 1 , a dual-rod support polar axis tracking reflective converging system, including reflectors and trackers:

[0035] Reflector, including outer ring frame 1, cable net group 2, energy conversion device 3 and installation pole 4:

[0036] Outer ring frame 1, its structure is as figure 2 As shown, it includes an upper annular body and a lower annular body composed of 48 fixed joints 11 , 48 cross bars 12 and 48 intermediate bars 13 . Wherein, the length of the cross bar 12 is 653 mm, and the length of the middle bar 13 is 597 mm. Fixed joint 11, its structure is as Figure 4As shown, it is composed of a first clamping plate 111 and a second clamping plate 112, which are combined to form two horizontal connecting pipes and two branching connecting pipes, where one horizontal connecting pipe and the branching connecting pipe adjacent to the horizontal connecting pip...

Embodiment 2

[0040] Embodiment 2: The tracker of this embodiment is the same as that of Embodiment 1, and the reflector adopts a feed-forward structure.

[0041] refer to Figure 5 , the reflector includes an outer ring frame 1, a cable net group 2, an energy conversion device 3 and a mounting rod 4, the difference is that the reflecting surface formed by the cable net group 2 is in the shape of a rotating paraboloid, and the mounting rod 4 passes through multiple A rope connected to the outer ring frame is fixed on the rotation axis of the rotating paraboloid, and the energy conversion device 3 is fixed at the focal point of the rotating paraboloid.

[0042] In some extreme poses, the mounting rod 4 may interfere with the tracker, and the size and layout of the tracker need to be considered reasonably.

[0043] A rotary motor is installed on the rotary hinge that the second drive rod 8 is connected with the fixed rod 6, and the rotation of the motor drives the second drive rod 8 to move ...

Abstract

The present invention proposes a double-rod support polar axis tracking reflective convergence system, aiming to solve the technical problems of large tracking accumulation error and large end driver load existing in the prior art. It includes a reflector and a tracker. The reflector includes an outer ring frame, a cable net group, an energy conversion device and a mounting rod; the tracker includes a support platform, a fixed rod, a first drive rod and a second drive rod; the lower end of the fixed rod is connected to the The support platform is fixedly connected, and the upper end is connected with the outer ring frame through a Hooke hinge; the upper end of the first driving rod is connected with the outer ring frame through a ball hinge, and the lower end is connected with the supporting platform through a ball hinge; the second driving rod is connected by a rotating hinge The free end of one short rod is connected with the rotating hinge installed on the fixed rod, and the free end of the other short rod is connected with the lower ring body of the outer ring frame through the Hooke hinge; the first drive The rod and the second driving rod jointly drive the outer ring frame to drive the reflective surface to track the sun.

Description

technical field [0001] The invention belongs to the technical field of mechanical components, and relates to a polar axis tracking reflective and converging system, in particular to a polar axis tracking reflective converging system supported by double rods, which can be used for reflecting and converging solar energy on the ground. Background technique [0002] With the depletion of traditional energy and the increasing environmental problems, the development and utilization of new energy is imminent. Among the many renewable energy sources, solar energy is one of the new energy sources with the greatest development potential. At present, solar thermal power generation systems mainly include trough system, tower system and dish system, among which the dish system has the highest conversion efficiency, and the annual average conversion efficiency can reach about 23%. [0003] Dish solar tracking mechanisms mainly include horizontal and polar axis. Compared with the horizon...
