Marine observation experiment teaching device

Abstract

The invention relates to a teaching device simulating the marine environment, and provides a marine observation experiment teaching device comprising a pressure resisting box body, a sealing gasket, a cable, a pressure resisting box cover, a compressed air pipeline, an air compressor, a controller, an compressed air pipeline, a sea salt pool, a three-way electromagnetic valve, a water pipe, a heat pump system, seawater, a marine observation instrument, a water pump, an electromagnetic valve, air cylinders and a water pipe. An enclosed pressure resisting space is formed by the pressure resisting box body, the pressure resisting box cover and the sealing gasket. The marine observation instrument is arranged in the seawater loaded in the pressure resisting box body. The controller controls compressed air and simulates the change of the seawater pressure. The controller controls the water pump to simulate ocean current. The controller controls the heat pump system to perform refrigeration or heating. The temperature of the seawater is changed through a heat exchanger so as to simulate the change of the seawater temperature. The controller controls telescoping of the air cylinders. The four or six air cylinders simulate shaking of the ship under the control of the controller. The controller controls the three-way electromagnetic valve to simulate the change of the salinity of the seawater. The teaching effect can be improved and the teaching quality can be enhanced by the device.

Description

technical field [0001] The invention relates to an experimental teaching device for the subject of physical oceanography, in particular to a test device for simulating changes in ocean temperature, pressure and salinity. Background technique [0002] Going out to sea to observe marine physical phenomena is a compulsory course for marine physics majors. At present, in the process of experimental teaching, according to the instruction manual of the instrument, the instrument is debugged and tried on the experimental table. Since the conditions of the sea experiment are not simulated, the experimental effect is not ideal. Instruments and incidents of instrument loss occur from time to time. [0003] From the perspective of teaching, if the conditions at sea can be simulated in the laboratory, students can use instruments proficiently and master various skills of ocean observation. When going out to sea, even if the wind is high and the waves are rough, you can be familiar wit...
