Emergency rescue water supply guarantee technology and equipment can play an important role in ensuring life safety and safeguarding maritime rights and interests in field expeditions, scientific expeditions, rescue and emergency situations, etc., and have great demand.
The handheld seawater desalination device has the advantages of compact structure, small size, stable system, and wide applicability. The device is simple to operate. By placing the filter in the water intake point and pressing the device handle, drinking water can be obtained. This makes it possible for individuals to convert seawater and brackish water into drinking water through a single device, meeting the demand for short-term small amounts of fresh water in special occasions. It is suitable for field expeditions, scientific expeditions, rescue and emergency situations, etc.
Its main structural and process features are: using human power drive as the only power input, eliminating the restriction of lack of power supply; adopting negative pressure design for the pretreatment filter, eliminating the need for a low-pressure water supply pump; converting the pressing of the handle into the reciprocating motion of the piston through a connecting rod structure to pressurize low-pressure seawater, replacing the high-pressure pump; adding an energy recovery device to significantly reduce human power consumption; adopting an integrated block structure to simplify pipeline connections; multiple integrated blocks form the main body of pressure boosting, energy recovery, and fluid delivery, which are fastened by simple bolts to greatly reduce the device volume and also provide the possibility for remote equipment maintenance; the main body of the device adopts engineering plastics and fiberglass, and a small number of metal parts use titanium material, minimizing the device weight.
