Embodiment Construction

[0028] As mentioned above, the present invention adopts the technical scheme of electromechanical integration intermittent operation tracking.

[0029] figure 1 Shown is the monolithic structure embodiment that is used for solar energy heat collection, and its structure comprises base 9, azimuth tracking driver 1, elevation angle tracking driver 2, trough-shaped parabolic concentrator 5, vacuum glass tube 4 with heat pipe and for solving Rotary valve 3, rotary valve 6 and other parts set for the problem of hard pipe rotation. The azimuth tracking driver 1 is arranged on the base 9, and is connected with the elevation angle tracking driver 2 after the rotary valve 6 is installed on its output shaft. A rotary valve 3 is installed at each end. The vacuum glass tube 4 with heat pipe is installed on the focal point (line) of the trough-shaped parabolic concentrator 5 through a bracket.

[0030] Both the azimuth tracking driver 1 and the elevation angle tracking driver 2 are prov...

Abstract

The invention relates to a method and a device to automatically track sun according to time control. Based on the basic principle of earth running around sun, the real sun time and declination angle would be calculated. Thus, the elevation and the track running time would be calculated from sunrise to sundown, and the relationship of the tracking running of that day and the next day as well. Then, it would return to the location of sunrise when sundown. The track device is made up of elevation track driver and location track driver. The drivers are made up of reducer that use micro deceleration electromotor or step motor as power a Solar energy collector is fixed on the driver by supporting. The electric machine is controlled by computer. The invention is easy to make, low cost, convenience to maintain, and has a broad application range.

Description

[0001] Field [0002] The invention relates to a method and device for controlling and tracking the sun according to time, which can be widely used in the solar energy industry. Background technique [0003] A high-precision, low-cost, fully automatic and ideal sun tracking device is of great significance to solar energy utilization, which is well known to people engaged in the solar energy industry. For example, it is used for photovoltaic power generation. Compared with the fixed type, its vertical sunlight The light-receiving area can be increased by at least 200% in summer, 150% in spring and autumn, and 100% in winter, so the cost of photovoltaic power generation can be greatly reduced. If it is used together with a parabolic concentrator, it can obtain a high temperature of several hundred degrees. But, although there are various (comprising by time) inventions of sun tracking devices, practical products have not been seen yet. Contents of the invention [0004] In or...
