Inflation device and inflation method for underwater sampler

Abstract

The invention provides an inflation device and an inflation method for an underwater sampler, and relates to the field of underwater sampling. The inflation device comprises an air containing part, a piston, an air cylinder and a limiting piece are arranged in the air containing part, the piston covers an air cylinder opening, the limiting piece is located on the side, away from the top of the air cylinder, of the piston, and the maximum air containing space of the air containing part is determined by the distance between the limiting piece and the top of the air cylinder; the sensors are arranged on the two sides or any side of the piston; the air pump is connected with the air inlet of the air containing part so as to input air into the air containing part; the control module is connected with the sensor and the air pump and is used for receiving a pressure or pressure intensity signal of the sensor and transmitting a start-stop signal to the air pump; wherein according to the input water depth data, the control module controls the starting duration of the air pump, so that the air containing part contains the air with the set pressure. According to the invention, the power cost of the mechanical sampler is reduced and the automation degree of the mechanical sampler is improved through the accurately designed inflating device.

Description

technical field [0001] The invention relates to the field of underwater sampling, in particular to an inflating device and an inflating method for an underwater sampler. Background technique [0002] In the process of underwater scientific research, water bodies at different depths need to be sampled. In the prior art, electronic samplers are generally used for sampling. When used in an underwater environment, the electronic sampler is prone to problems such as water inlet short circuit, especially in the scene of high water temperature and highly corrosive industrial wastewater, or in the scene of complex underwater electromagnetic environment. Suitable for use with electronic samplers. Moreover, the cost of an electronic sampler that can meet the above environmental requirements is high. The traditional mechanical sampler has a low degree of intelligence and needs to cooperate with other equipment such as underwater robots to complete the sampling of a specific water dep...
