[0015] to combine figure 1 with figure 2 , the seabed sand sampling device comprises a rectangular box-shaped sampling box 1, a waterproof motor 5 is installed at the bottom of the sampling box 1, a stirring blade 6 or a drill bit are installed on the output shaft at the bottom of the waterproof motor 5, and two annular rings are arranged on the top of the sampling box 1. Hanging ring 8, the top of the sampling box 1 is vertically provided with a circular pipe-shaped liquid inlet pipe 2, and a remote-controlled electromagnetic valve 4 is installed on the liquid-injected pipe 2, which can realize free control of the remote-controlled electromagnetic valve 4 from a long distance. When the remote-controlled electromagnetic valve 4 is opened, Seawater can enter the sampling box 1 from the liquid inlet pipe 2, and when the remote control electromagnetic valve 4 is closed, seawater cannot enter the sampling box 1 from the liquid inlet pipe 2. The side bottom of the sampling box 1 ...

The invention discloses a seabed sandy soil sampling device, relating to the field of mechanical equipment, the seabed sandy soil sampling device connects the power supply device on the boat, the remotely controlled electromagnetic valve and the waterproof electric motor by a longer cable, then the remotely controlled electromagnetic valve is closed, the end cap of the drain pipe is screwed tightand the two hanging rings are suspended by a lifting rope. The sampling box is lowered to the seabed while sampling, the waterproof motor is started to drive the stirring blade or the drill bit to rotate to stir up the sandy soil on the seabed, the remote control electromagnetic valve door is opened by remote control after a period of time, and the sea water with the sandy soil is piped into the sampling box from the liquid inlet pipe. After the sampling box is fully filled, the lifting rope is pulled, and the sampling box is hung out of the sea surface. Then the end cap is unscrewed discharging the seawater from the sampling box to the filter screen, the sea water is leached out and the seabed sandy soil sample is obtained. The seabed sand sampling device is simple in design, unlikely tomalfunction, low in cost, good in working stability and capable of quickly taking out the sandy soil sample of the seabed surface layer.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular, the invention relates to a seabed sand sampling device. Background technique [0002] The vast ocean floor is rich in mineral resources, including cobalt-rich crusts, hydrothermal sulfide ores, etc., which have huge economic value and strategic significance. The deep sea is one of the few unknown regions on earth. Scientists are interested in deep sea mineral composition, mineral age, mineral formation mechanism, mineral physical and mechanical properties, and the biological and environmental conditions around minerals. These studies covering multiple disciplines of marine geology, marine biology, marine chemistry, marine physics, and marine mining require a large number of deep-sea mineral samples. Most of the existing seabed sand sampling devices are designed in the form of drilling rigs, the design is relatively complicated, the manufacturing cost is too high, and the sampli...
