Solar drinking-water collector and solar photovoltaic generating set

Abstract

The invention provides a solar drinking-water collector, which comprises a support, a condenser arranged on the support and a vacuum heat-collecting tube which is fixed above the condenser and can receive reflected light rays of the condenser. The vacuum heat-collecting tube comprises a plurality of vacuum heat-collecting straight tubes which are arranged in parallel and U-shaped vacuum elbows for communicating the two adjacent vacuum heat-collecting straight tubes; the U-shaped vacuum elbows are arranged at the left and right ends of the two adjacent vacuum heat-collecting straight tubes at intervals; an inlet and an outlet of the vacuum heat-collecting tube are respectively positioned upper and lower ends of the condenser; the support also comprises a steering mechanism and a steering control mechanism; the steering mechanism comprises a vertical steering mechanism and an axial steering mechanism; the vertical steering mechanism is used for adjusting the gradient of the support and the condenser under the control of the steering control mechanism; and the axial steering mechanism is used for enabling the support and the condenser to rotate along a central shaft thereof under the control of the steering control mechanism. The invention also provides a solar photovoltaic generating set for the solar drinking-water collector.

Description

technical field [0001] The invention relates to a solar device, in particular to a solar drinking water, heat collecting device and a solar photovoltaic power generation device. Background technique [0002] Solar energy is a kind of pollution-free clean energy, and it has received great attention today when human beings are facing two major survival issues of energy crisis and environmental protection. Most of the currently commercially available solar water heaters are solar water heaters, and most of them are single water heaters, which belong to the slow heating type heat collection, and the heat collection temperature is not high, and the practical value is low especially in winter. [0003] The current heating method used by solar water heaters is to absorb light energy through the heat transfer medium and heat the cold water in the heating tube. The hot water stays in the heating tube for a long time, and some hot water will stay in the heating tube for a long time. ...

AI Technical Summary

Problems solved by technology

At present, most of the devices using solar energy on the market are solar water heaters, most of which are single-body water heaters, which belong to the slow heating type heat collection, the heat collection temperature is not high, and the practical value is low especially in winter

[0003] The current heating method used by solar water heaters is to absorb light energy through the heat transfer medium and heat the cold water in the heating tube. The hot water stays in the heating tube for a long time, and some hot water will stay in the heating tube for a long time. Without circulation, the water heated for a long time will produce a large amount of nitrite and other harmful substances to the human body. Therefore, the hot water produced by the current solar water heater can only be used for bathing, heating and other domestic water, but not for water supply. people drink directly

[0004] In addition, most of the solar water heaters currently on the market use fixed angles and positions, and cannot automatically follow the movement of the sun. Most of the time, the sunlight is irradiated on the heat collecting device obliquely, so the utilization rate of solar light is low.

Although tracking devices for collecting sunlight are also installed in some devices, the structure is relatively complicated and consumes a lot of energy, which also affects the effective efficiency of solar heat collectors.
