Problems solved by technology

However, the plug-in movable irrigation system composed of plug-in underground drippers is not specially designed for drought-resistant supplementary irrigation after all. It lacks system considerations, does not have a fast-moving system head, a pressurization system, etc., and cannot take water from a long distance.

Abstract

The invention relates to a drought resisting supplementary irrigation system, comprising a submersible pump, an air compressor, a vehicle-mounted water tank, a vehicle-mounted compressed air energy storage tank and a plug-in removable irrigation system and the like. In a water source place, water is injected into the vehicle-mounted water tank by virtue of the submersible pump, air is inflated into the vehicle-mounted compressed air energy storage tank by virtue of the air compressor, after the water tank is full of water and the compressed air energy storage tank is full of the air, the water tank and the compressed air energy storage tank are conveyed beside a field which is in drought and is installed with the plug-in movable irrigation system in advance, the plug-in movable irrigation system is connected to release the compressed air in the vehicle-mounted compressed air energy storage tank into the vehicle-mounted water tank under a constant pressure, the water in the vehicle-mounted water tank is enforced to be conveyed to the plug-in movable irrigation system, and irrigation is carried out. The system provided by the invention has the characteristics that: water is saved, the utilization factor of the irrigation water can be more than 95%; cost is saved, no diesel or gas oil is used except transportation; the efficiency is high, system equipment can be reused and can rapidly move; and the adaptability is strong, water can be got remotely, and the problem that supplementary irrigation is carried out on scattered field blocks which do not meet irrigation conditions can be solved.

Description

Technical field: [0001] The invention relates to the field of farmland irrigation, in particular to a supplementary irrigation system for drought resistance. Background technique: [0002] The most effective emergency measure taken to deal with drought is supplementary irrigation, but the existing irrigation equipment that can be used for emergency, such as mobile sprinkler irrigation machine, must work close to the water source, even if it is used, it can be used at a long distance from the water source. The self-propelled reel sprinkler irrigation machine, the maximum distance from the water source is not more than 500 meters, but most fields suffering from severe drought cannot meet this condition. In addition, mobile sprinklers use spraying methods to irrigate, which are greatly affected by wind and evaporation. The irrigation water utilization rate is not the highest among the existing irrigation methods. In severe drought conditions, precious water sources cannot exert maxi...
