A solar water heater

Abstract

The invention provides a solar water heater and aims at solving the problem that an existing bracket does not have the adjustability and the shielding function and the problem that an existing water tank is easily damaged in rainy, snowy and hail weathers and improving the heat preservation performance of the water tank in rainy and snowy weathers. By arranging a driving gear, a driven gear and the like below a mounting frame to drive the mounting frame to rotate, angle adjustment of the mounting frame is realized, and angle adjustment of a heat collection pipe is finished; the mounting framecan be adjusted according to seasonal variation, difference of latitude regions and different angles of sunlight irradiation, so that solar illumination is utilized to the maximum; the water tank is prevented from being damaged in severe weather through an adjustable first shielding device, and an adjustable second shielding device exerts the protection effect to a heat collector and solves the problem of rain and snow accumulation at the same time to exert the heat preservation effect, so that the service lives of the water tank and the heat collector are prolonged; and by heating a heat transfer medium through a heating pipe, drying of a shielding plate and a protective plate are accelerated, and rainwater accumulation is avoided.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar water heater. Background technique [0002] Solar water heater is a heating device that converts sunlight energy into heat energy, and heats water bears from low temperature to high temperature, so as to meet the needs of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure, and vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. [0003] Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. Get the hot water you need. However, the existing vacuum tube type household solar water heaters have the following problems: one is that th...

Problems solved by technology

However, the existing vacuum tube type household solar water heaters have the following problems: one is that the bracket is generally a fixed structure and does not have adjustability, so in the case of seasonal changes and different latitudes, the angle of sunlight irradiation is also different. , so the existing solar water heaters have the problem that they cannot be adjusted with different regions and seasons, and cannot maximize the use of solar light; the second is that they do not have a shielding function, and the water tank and heat collecting tubes are easy to be damaged in hail, rain and snow weather. Damaged, the effect of heat preservation and heating becomes poor
