The karst area is influenced by the special geological background, the ecological environment is fragile, the water and soil loss is serious, and farmers are used to collect and store rainwater by using a reservoir (box). Meanwhile, with the development of social economy, energy utilization modes of farmers are more and more abundant. The karst region has abundant solar energy resources, large radiant quantity, sufficient illumination, 1360h annual average sunshine hours and sufficient illumination, the solar water heater is the most direct and common mode for solving the energy problem of the karst plateau region by utilizing solar energy at present, and water utilized by the solar water heater is led from a reservoir (tank). The area is located in a subtropical humid monsoon area, is in the same rain and heat period, is rich in biological diversity, and has higher water hardness due to the special geology and lithology of the karst area. In addition, in regions with serious karst stony desertification, the water and soil conservation conditions are not good, so that a large amount of silt is contained in the water in rainy seasons. In summary, the water in the water storage device exposed to the outside comes from the accumulation of rainwater or the ground water drawn into the mountain, and thus algae and small aquatic animals are likely to grow and scale is likely to be formed. When water flows into the solar water tank through the water inlet pipe, because the gaps are small, impurities such as algae, remains of aquatic animals, incrustation and the like in the reservoir (tank) can be accumulated and blocked in the water inlet pipe, so that the water inlet efficiency is greatly reduced, and even water cannot enter. Therefore, the working efficiency of the solar water heater is low in the working process, even no water is generated, and the service life of the solar water heater is greatly reduced. Meanwhile, the general culture level of farmers in the karst region is low, the economic level is not high, after the water inlet pipe of the solar water heater is blocked, the farmers cannot clean the water inlet pipe or the cleaning mode is improper, the water inlet pipe can be scalded by hot water flowing back in the water heater, but a professional maintenance worker is required to maintain the water inlet pipe, so that relatively useless cost is generated each time, and the use intention of the farmers is greatly reduced.
