Solar water heater with solar photovoltaic power generation system

Abstract

The invention belongs to the technical field of solar water heaters, and particularly relates to a solar water heater with a solar photovoltaic power generation system. The solar water heater comprises a water tank, a heat collection pipe, a supporting plate, a frame body and a controller, wherein the water tank is rotationally connected to the upper portion of the supporting plate, and the end, away from the water tank, of the heat collecting pipe is inserted into the frame body. the solar water heater is further provided with a rotating module, wherein a placing platform is arranged on the right side of the water tank, and the motor is fixedly connected to the placing platform through bolts. Two rotating rollers are fixedly connected with photovoltaic power generation panels correspondingly, and the photovoltaic power generation panels generate power and are used for heat preservation of the water tank. A sunlight sensor is arranged on the front end surface of the frame body. The sunlight sensor senses the angle of the sun and sends a signal to the controller so as to control the motor to rotate, the motor drives the rotating rollers to rotate, and the rotating rollers drive the water tank, the heat collecting pipe, the frame body and the photovoltaic power generation panels to rotate, so that the heat collecting pipe is always located in a relatively large illumination area, and the energy utilization rate of sunlight is increased.

Description

technical field [0001] The invention belongs to the technical field of solar water heaters, in particular to a solar water heater with a solar photovoltaic power generation system. Background technique [0002] Solar water heaters convert sunlight energy into heat energy, and heat water from low temperature to high temperature, so as to meet the hot water use 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. At present, vacuum tube solar water heaters dominate, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related accessories. The conversion of solar energy into heat mainly depends on the heat collecting tubes. The heat collecting tube utilizes the principle that hot water floats up and cold water sinks, so that the water generates micro...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, it solves the low energy utilization rate caused by the reduction of sunlight when the heat collecting tube is fixed when the sun shines on the back of the heat absorbing layer; and the traditional solar water heater is outdoors for a long time, and the heat collecting tube is easy to be covered with dust. Shading, the problem of causing energy loss from sunlight
