Problems solved by technology

[0003] At present, the technical means of seabed sampling, especially deep sea sampling, are very limited. Compared with developed countries, the means of seabed exploration in my country is single, and the seabed sampling equipment is backward. It is too heavy, and it is very difficult to hang or recover, especially when it is applied to the deep sea or even the whole sea depth. When sampling the sedimentary mud bed on the seabed, the mud bed structure will often be destroyed and the original sediment space will be changed. distribution, affecting the exploration effect

Embodiment 1

[0026] The present invention provides such Figure 1-4 The shown sampling exploration equipment includes a housing 1, a first electric push rod 2 is provided on the inner top of the housing 1, and a sampling device is provided at the output end of the first electric push rod 2, and the sampling device includes The isolation cover 3, the inner top of the isolation cover 3 is provided with a second electric push rod 4, the output end of the bottom of the second electric push rod 4 is provided with a motor 5, and the output shaft of the motor 5 is connected to a sampling cylinder 6 through transmission, so The top of the sampling cylinder 6 is provided with a turret 26, the bottom of the sampling cylinder 6 is provided with a sawtooth cutting piece 7, the bottom surface of the sampling cylinder 6 is provided with a closed groove 8, and the inner bottom of the isolation cover 3 is provided with a third electric pusher. Rod 9, the output end of the third electric push rod 9 is prov...

Embodiment 2

[0036] A sampling exploration method, including the sampling exploration equipment, also includes the following steps:

[0037] S1: The first electric push rod 2 pushes the isolation cover 3 to isolate the external sea water, reducing the water pressure for sampling, and the motor 5 drives the sampling cylinder 6 to rotate, so that the sawtooth cutting blade 7 cuts the mud bed;

[0038] S2: push down the second electric push rod 4 to press down the sampling cylinder 6 to sample, the mud bed rises in the sampling cylinder 6 and pushes the piston 12 to rise;

[0039] S3: The water in the sampling cylinder 6 is discharged from the drain hole 14, and under the action of the one-way valve 15, only the mud bed remains;

[0040] S4: After the sampling is completed, the second electric push rod 4 retracts, the third electric push rod 9 pushes the closing plate 11 to close the closing groove 8, the blade on one side of the closing plate 11 can effectively cut off the mud bed, and the c...

Abstract

The invention discloses a sampling exploration device and method. The sampling exploration device comprises a shell, wherein the top part of the inner side of the shell is provided with a first electric pushing rod, the output end of the first electric pushing rod is provided with a sampling apparatus, the sampling apparatus comprises a separation cover, the top end of the inner side of the separation cover is provided with a second electric pushing rod, the bottom output end of the second electric pushing rod is provided with a motor, the output shaft of the motor is connected with a sampling cylinder in a transmission manner, and the top end of the sampling cylinder is provided with a rotation bracket. The sampling exploration device is provided with the sampling apparatus, the samplingcylinder is driven by the motor to rotate, a sawtooth cutting blade is used for cutting a sludge bed, the sampling cylinder is pressed by the second electric pushing rod to collect a sample, the sludge bed rises in the sampling cylinder and pushes the piston to rise, the water in the sampling cylinder is discharged from a water discharging hole, only the sludge bed is reserved under the effect ofa one-way valve, after the sampling is completed, the second electric pushing rod is retracted, and a third electric pushing rod pushes a closing plate to close a groove, so that the sample can be prevented from dropping, and the seawater can be prevented from damaging the sludge bed.

Description

technical field [0001] The invention relates to the technical field of marine exploration and development devices, in particular to a sampling exploration equipment and method. Background technique [0002] The ocean accounts for 70.78% of the earth's total area, and the depths of the ocean are widely covered with a layer of mysterious but very valuable seabed sediments. Long-term changes are of great significance Sampling and in-depth research on seabed sediments can enable human beings to obtain very important scientific values ​​in the fields of marine scientific research, marine environmental research, marine resource exploration, and marine engineering exploration. The development of the ocean has important strategic significance. [0003] At present, the technical means of seabed sampling, especially deep sea sampling, are very limited. Compared with developed countries, the means of seabed exploration in my country is single, and the seabed sampling equipment is back...
