Water energy automatic cleaning device for the outer wall of solar vacuum tube

Abstract

The invention discloses an automatic hydropower cleaning device for the outer walls of solar vacuum tubes. The device comprises a push-and-pull type cleaning assembly, a hydropower driving assembly and a water distribution control valve, wherein the push-and-pull type cleaning assembly consists of a plurality of cleaning heads and a horizontal beam; the hydropower driving assembly comprises two guide rods; an output mechanism for providing push-and-pull force for the horizontal beam, a telescopic water storage device for driving the output mechanism, and an elastic mechanism are arranged on each guide rod; the telescopic water storage devices are capable of providing clean water for the push-and-pull type cleaning assembly; a water distribution control valve enables the water to flow into the telescopic water storage devices for water storage and energy storage, and enables the telescopic water storage devices to be communicated with the push-and-pull type cleaning assembly so as to provide cleaning water for the cleaning heads. According to the hydropower automatic cleaning device, through utilizing the pressure of tap water for providing power as well as the ingenious design for controlling the working state, the use of electronic devices is avoided, the consumption of electric energy is not needed, and the device is convenient for mounting, and safe to use, and moreover, as the methods of water washing and movable wiping are adopted for performing cleaning on the outer walls of the vacuum tubes, the device is high in cleaning efficiency and good in effect.

Description

technical field [0001] The invention relates to the field of solar energy application equipment, in particular to a device for cleaning and dedusting the outer wall of a solar vacuum tube. 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 structural forms. Among them, vacuum tube solar water heaters are the main ones, which are widely used all over the country. The vacuum tube of the vacuum tube solar water heater is composed of an inner glass layer and an outer glass layer. There is a vacuum layer for heat insulation between the two. The inner glass layer is coated with an absorbing coating to maximize the absorption of solar energy, while the outer glass layer The layer is transparent so th...

Problems solved by technology

This type of scheme has the following technical deficiencies: First, it requires a separate water tank, solenoid valve, booster pump, tubular cleaning nozzle, time relay and an operating unit installed indoors, involving many components, and the cost required to achieve its purpose It is relatively high, and it needs to consume a certain amount of electric energy during the working process, which reduces the energy-saving effect of solar water heater products; secondly, the electrical components need to be connected by wires during the installation process, and the solar water heater is located on the roof, which is often far away from the room. The design is difficult, the overall installation is difficult, and the coexistence of the waterway and the circuit has a large safety hazard; thirdly, the position of the tubular cleaning nozzle used in it is fixed on the vacuum tube, and it cannot effectively clean the tube wall of the vacuum tube. If it is transformed into a form that can slide along the vacuum tube, another set of driving mechanism needs to be configured, which further increases the complexity of its structure and increases its cost, which is not conducive to implementation and promotion
