Energy-saving rainwater collector

Abstract

The invention relates to the technical field of rainwater resource collection and utilization, in particular to an energy-saving rainwater collector. The energy-saving rainwater collector comprises a rainwater collecting groove, a water guide hose and a water accumulating tank. The energy-saving rainwater collector is characterized in that the water collecting groove is a disc-like rainwater collecting plate; a water guide hard pipe consisting of a branch pipe and a horizontal pipe is arranged between the rainwater collecting plate and the water guide hose; the device is adsorbed to window glass by a suction plate arranged at the tail end of the horizontal pipe; a water outlet hole is formed in the lower end of the horizontal pipe at the position, corresponding to a dripping groove, in the water guide hard pipe, and is connected with a sucker placement pipe; a groove is formed in the upper end of the horizontal pipe corresponding to a water outlet; a sucker placement opening is formed in the groove; the lower end of a sucker is matched with the sucker placement pipe; and the upper end of the sucker pipe is led out through the horizontal pipe and the sucker placement opening in sequence and is propped against the inner wall of the dripping groove. The dripping groove is fully filled with rainwater under the condition of a heavy rain or a storm; and the rainwater can flow along the sucker, so as to enter the water accumulating tank along the water guide hose, so that the energy-saving rainwater collector has the advantages of simple structure, energy conversation, portability, low cost, good water collecting effect and the like.

[0002] As we all know, China is one of the 13 countries in the world that suffers from severe water shortage, and is also one of the countries that are seriously short of agricultural water resources. The shortage of agricultural water resources has become a long-term factor restricting agricultural development after the arable land resources. Under limited conditions, it is necessary to rely on science and technology to greatly increase land productivity, accelerate the development of water-saving agriculture, and diversify the use of water resources through multiple channels. The ecological environment in western China is fragile, and afforestation is one of the effective measures to improve the ecological environment. However, drought Water shortage directly affects the survival rate and growth of afforestation on slopes in mountainous areas. Especially at present, there are about 248 million urban households in the country. Each household waters 0.5 tons of flowers and flushes 18.25 tons of toilets a year. The total consumption of tap water is about 4.65 billion tons. 1.26 million, about 10 million people, with an annual consumption of 56.25 million tons of tap water. Industrial and commercial enterprises: 2,387 large-scale companies, about 20 million people, consuming 140 million tons, 7,790 medium-sized enterprises, about 7 million people, consuming 48 million tons, such a large water resource user can easily lead to serious waste of water resources

[0003] The current urban construction has created a large number of impermeable ground, roofs, concrete and asphalt pavements. The runoff coefficient of this type is generally 0.9, and nearly 90% of the rainfall will cause surface runoff loss. This is not only a huge waste of water resources, but also It has increased the burden on urban drainage facilities and increased the probability of urban rainwater floods. Urban community rainwater utilization has a history of decades in developed countries. Some countries and regions have already had successful experience in urban rainwater utilization. In the United States, Countries such as Japan, Germany, India, and many cities in Taiwan have begun to collect rainwater from roofs and platforms for non-drinking domestic water, such as flushing toilets, greening lawns, and constructing artificial landscapes. Non-traditional water sources such as non-traditional water sources are of great significance to the sustainable development of the economy and society. However, the current rainwater collection devices generally collect rainwater from the roof, and it is difficult to collect rainwater under the eaves. In particular, some rainwater harvesting devices are heavy and energy-consuming, and have shortcomings such as low collection effect
