Solar water heater with double-shaft complementary light tracking

Abstract

A solar water heater with double-shaft complementary light tracking comprises a bracket, a water tank, and a vacuum glass heat collection tube, wherein the vacuum glass heat collection tube is arranged and fixed on a side face of the bracket to form a heat collection plane, the water tank is mounted above the bracket, and the bracket includes a bottom bracket, a ridge bracket, electric push rods,and a water tank bracket. The water tank bracket is fixedly mounted above the ridge bracket, the ridge bracket is obliquely mounted with respect to the horizontal plane and has two sides connected totwo ends of the water tank bracket, respectively, and between two top points of the ridge bracket is provided a connection plate; two electric push rods have upper ends symmetrically hinged with two sides of the connection plate, respectively, have lower ends hinged with a mounting plane, and have driving motors connected to a control system; and the control system is connected to a solar panel mounted on the ridge bracket, the low end of the ridge bracket is fixedly connected to the bottom bracket, and the bottom bracket is hinged with the mounting plane through a spherical hinge. The inventive water heater adopts complementary double-shaft photoelectric detection tracking and sun trajectory tracking to track sunlight, so as to ensure long-time working accuracy and efficiency of light tracking system.

Description

technical field [0001] The invention belongs to the technical field of solar water heaters, and in particular relates to a solar water heater with dual-axis complementary light tracing. Background technique [0002] As a green and energy-saving product, solar water heaters are favored by more and more consumers. In order to improve the collection and utilization rate of solar energy, the existing solar water heaters are designed with solar automatic tracking systems, so that the sun's rays are always irradiated vertically within the effective lighting time. 7%。 To the collection surface of the light collector, so that the light collector can obtain solar energy to the maximum during the effective illumination time. Theoretical analysis shows that: the sun tracking and non-tracking, the energy receiving rate difference is 37. 7%. [0003] Solar tracking methods can be divided into fixed type, single-axis tracking type and dual-axis tracking type according to the form. The fix...

Problems solved by technology

[0003] Solar tracking methods can be divided into fixed type, single-axis tracking type and dual-axis tracking type according to the form. The fixed type solar support is currently widely used due to its long production history, mature technology, and easy installation and use. Installation, its structure is fixed, resulting in low utilization rate of solar energy, can not be heated to the required temperature, and additional auxiliary power is required to increase the cost; single-axis tracking only tracks the sun in the azimuth angle, and makes seasonal adjustments in the altitude angle, although Compared with the fixed bracket, the solar energy utilization rate has been improved, but its tracking accuracy is low, and the incident angle of light is not the optimal value; the dual-axis tracking is to track the sun's trajectory in two directions of azimuth and altitude, and ensure that the sun's rays are in the best possible position in real time. Excellent angle of incidence, solar energy utilization reaches the maximum
