Embodiment 1
[0056] Embodiment 1: Multi-parabolic mirror vacuum tube utilization system
[0057] This picture is a side view, the solar mirror (2) is four parabolic reflectors (2), a straight-through vacuum tube is arranged in the focal line area, a heat pipe is arranged inside the vacuum tube, a solar coating is arranged on the vacuum layer of the vacuum tube, and the paraboloid The mirrors are arranged on a parabolic device, and each parabolic mirror is provided with a shaft, and the solar mirror can rotate along the rotating shaft (5). At the same time, there are rollers on the ground, which can roll on the ground. The drive to the solar mirror bracket (4) is realized, so that the drive through the rotating shaft (5) and the solar mirror bracket in the parabolic device are realized, the overall tracking of the solar energy is realized, and the four solar mirrors of the solar energy are passed through different Movement enables tracking of solar energy. The four parabolic mirrors use th...

[0058] Embodiment 2: Multi-glass mirror vacuum tube utilization system
[0059] Such as figure 2 As shown, this example uses two sets of glass reflectors to realize solar tracking, wherein each set of solar mirrors is two glass reflectors (2), and the two sets of glass reflector tracking systems are connected in series; the vacuum tube (1) is a double-pass glass tube , a metal pipe (13) is arranged inside the glass tube, and the heated fluid circulates inside the metal pipe, and heat transfer oil is used as the heat transfer fluid, which enters from one end of the metal pipe and discharges from the other end, so as to realize power generation, heating, Refrigeration and other applications. Four glass reflectors are fixed on three ring-shaped devices, the power drive device is a motor (6), the power transmission device is a gear mechanism arranged on the ring, and the motor drives the gear arranged on the ring through the gear mechanism , so that the glass mirror is rotated ...
Embodiment 3
[0060] Embodiment 3: Multi-Fresnel Mirror Array Tracking Vacuum Tube Utilization System
[0061] Such as image 3 As shown, this case is a multi-mirror array tracking system, using four Fresnel mirrors (2), the power drive device is a motor (6), and the motor drives two sets at the focus through the power transmission device (9) of the chain. The gear on the wire rotating shaft (5) is provided with a driving device (12) for each ring (3) that provides support for the solar mirror at the same time, so as to realize the driving of each ring, so that the rotation of the solar mirror can be realized And for the multi-directional tracking of the drive of the solar mirror bracket, the solar tracking of the 2*2 array is realized. A heat pipe heat transfer system is arranged inside the two vacuum tubes, and a heat exchanger (11) is arranged at the condensation end of the heat pipe, so that Realize the utilization of various thermal energy of solar energy.
