Problems solved by technology

but expensive
[0004] Existing tracking devices for observing solar activity are accurate but expensive; among them, the traditional differential pressure and control-release solar trackers have complex principles and structures; clock-based and program-controlled tracking devices have accumulated errors And it cannot be automatically eliminated; the photoelectric tracking device is more accurate in tracking, the principle is simple, and it is easy to implement, but it cannot continuously track the sun's movement, and the high price is the problem existing in the current solar tracking device

Embodiment Construction

[0012] like Figure 1-Figure 2 As shown, the differential pressure solar automatic tracking device of the embodiment of the present invention includes a pressure difference generating device, a transmission mechanism, and a night reset device. It is composed of working medium metal sealing tube and metal deformation actuator, and a group of gas tubes are set around the reflector as the tracking sensor of the hour angle; when the sun shifts, affected by the middle partition, the two organic working medium tubes are affected by the sun The irradiation is different, and they are gathered in the pressure tubes on both sides. When the pressure reaches a certain value, the pressure difference will deform the metal, and the actuator will send a tracking signal, and the pressure will drive the tracking power to drive the mirror to track the sun; when the mirror is aligned with the sun, the The pressure is balanced, and the differential pressure metal deformation actuator returns to it...

Abstract

The invention belongs to the field of solar tracking supports, and applies to solar photovoltaic inexact automatic tracking. The differential-pressure-type automatic solar tracking device comprises a pressure difference generation device, a transmission mechanical device and a nighttime resetting device, wherein the pressure difference generation device comprises a middle partition board, organic working medium metal sealing tubes embedded in paraboloid grooves in two sides of the partition board and a metal deformation actuator, a set of gas tubes are arranged on the periphery of a reflection mirror to serve as hour-angle tracking sensors. The invention aims to provide the differential-pressure-type automatic solar tracking device which can gather light through solar angle change to enable sealed organic media to expand and drive a differential pressure mechanical mechanism to rotate to track the sun.

Description

technical field [0001] The invention belongs to the field of solar tracking brackets and is suitable for solar photovoltaic inaccurate automatic tracking. technical background [0002] In terms of sun tracking: fixed inclination, horizontal axis tracking, fixed inclination azimuth tracking, oblique single-axis (or polar axis) tracking, dual-axis tracking, etc. are often used to reduce the incident angle of light on the receiving surface. Most tracking systems are automatically controlled by power electronics, the system is relatively complex and the cost of construction and maintenance is high. The initial investment of the single-axis tracking system is relatively small, and the structure of the tracking equipment is simple. However, since the incident light cannot always be parallel to the main optical axis, the effect of collecting solar energy is not ideal. [0003] Dual axis tracking system can be used in any kind of solar system to improve its operating efficiency. ...
