Solar water pipe heating and heat preservation device

Abstract

The invention discloses a solar water pipe heating and heat preservation device, which comprises a photovoltaic module, a micro inverter, heat preservation cotton and an electric heating wire, whereinthe heat preservation cotton is arranged on an inner layer of the photovoltaic module, and the electric heating wire is embedded in the heat preservation cotton; the photovoltaic module is electrically connected with the electric heating wire through the micro inverter; the photovoltaic module is used for receiving solar energy to generate direct current, and the micro inverter converts the direct current into alternating current and outputs the alternating current to the electric heating wire for heating. The device does not need commercial power, completely utilizes clean energy solar energy for power generation, supplies power to the electric heating wire to heat the electric heating wire, realizes heating and heat preservation of the water pipe, prevents the water pipe from being frozen and cracked and realizes self-sufficiency of electric power. Meanwhile, the convenience is greatly improved and fire hazards are avoided due to the fact that an external power source is not needed.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a solar water pipe heating insulator. Background technique [0002] At present, outdoor water pipes are still used in many rural areas. In winter, due to the low outdoor temperature, it is very easy to cause the water pipes to freeze and cannot supply water normally. What’s more, the water pipes will freeze and crack, which greatly troubles the rural water supply. At present, many families use thermal insulation cotton to coat the outdoor water pipes, but there is still the phenomenon that the water pipes are cracked by freezing. Most of the additional heat preservation measures currently on the market are to directly wrap the water pipe with the heating wire of the heat-insulating water pipe, but there are the following disadvantages: ①The heating wire of the heat-insulating water pipe needs to be connected to the power supply, resulting in the need to pull temporary...

[0002] At present, outdoor water pipes are still used in many rural areas. In winter, because the outdoor temperature is too low, it is very easy to cause the water pipes to freeze and cannot supply water normally. What’s more, the water pipes will freeze and crack, which greatly troubles the rural water supply. ; At present, many households use thermal insulation cotton to cover outdoor water pipes, but there are still phenomena of water pipes being cracked by freezing

Most of the additional heat preservation measures currently on the market are to directly wrap the water pipe with the heating wire of the heat preservation water pipe, but there are the following disadvantages: ① The heat preservation water pipe heating wire needs to be connected to the power supply, resulting in the need to pull temporary cables from the house, which is extremely inconvenient and There are safety hazards such as fire; ②The heating wire of the thermal insulation water pipe currently used is directly wound, and the resistance wire will be damaged after aging, which will cause the heating wire to contact the water pipe, and there is a great risk of electric shock; ③The heating wire of the thermal insulation water pipe currently used is entangled method, it is not easy to remove after the arrival of spring, in many cases it will damage the heating wire, resulting in the heating wire can not be reused
