Embodiment

[0031] As shown in FIGS. 1-2, a high-dam deep-reservoir stratified water sample and sediment core integrated artificial intelligence sampling device includes a sampling device main chamber 1, an attitude balance sensor 2, a propeller 3, a balance base 4, and a sampler body 5. The attitude balance sensor 2 and the sampler body 5 are disposed inside the sampling device main chamber 1; the propeller 3 is disposed outside the sampling device main chamber 1; and the balance base 4 is located at a bottom end of the sampling device main chamber 1. The sampler body 5 is mounted inside the sampling device main chamber 1 through a rack 11, both sides of the sampler body 5 are provided with the attitude balance sensor 2, and the sampler body is sequentially provided with a high frequency vibration sensor 6, an array type water collector 7, an array type sediment collector 8, a sealed cabin 9, and an illumination camera system 10 from top to bottom. The propeller 3 is a gas propeller, and two to four propellers are disposed outside the sampling device main chamber 1 and evenly distributed outside the sampling device main chamber 1. Moreover, a gas propeller may also be disposed outside the sampler body 5 to achieve the up-down displacement of the entire sampling device, thereby obtaining an optimal sampling point.

[0032] The array type water collector 7 is a multi-channel array type water collector, wherein the volume of each single-channel water collector ranges from 500 to 600 ml. The array type water collector 7 adopts vacuum negative pressure suction to complete. The depth of the collected stratified water sample is determined mainly by a water pressure sensing device. A motor sealed main chamber is provided in the middle of the array type water collector 7. The high frequency vibrator 6 is electrically propelled to provide energy for a sampling action of the array type sediment collector 8. The array type water collector 7 is further provided with a water quality multi-parameter analyzer (YSI, USA), which completes real-time observation of a specific water depth and an entire vertical-profile water body, and transmits monitoring data to a water surface operating system in real time.

[0033] The array type sediment collector 8 is a multi-channel array type sediment collector, and the length of a sampling tube of the sediment collector ranges from 50 cm to 200 cm. The array type sediment collector 8 is sealed by a vacuum negative pressure mode, the sampling tube of the array type sediment collector 8 is pushed into an underwater sediment without disturbance by the high frequency vibration sensor 6, and hard bottom sediment is effectively collected by thousands of times of micro vibration per minute, wherein the high frequency vibration sensor 6 is a high frequency acoustic vibration sensing device.

[0034] The high-dam deep-reservoir stratified water sample and sediment core integrated intelligent sampling device is further provided with a water intelligent operating interface, which effectively completes intelligent setting of a sampling process, visual control, and integrated intelligent sample collection. The present sampling device uses an umbilical cord as a safety rope of the sampling device for secondary protection.

[0035] At the beginning of sample collection, according to the characteristics of different deep reservoirs and the dine distribution law of water bodies, an operation interface is pre-set on a water surface operation platform to complete the accurate setting and remote control of a distance interval of stratified water samples. An umbilical cord is used as a safety rope of the sampling device for secondary protection. When the entire sampling device has a downward vector in water, the safety rope is slowly placed at a constant speed to provide traction energy for the entire sampling device. At a pre-set water depth, the attitude of the sampling device main chamber 1 is balanced by remotely controlling the propeller 3 and the attitude balance sensor 2, and the stratified water samples can be collected by the multi-channel array type water collector 7. In the profile collection process of the entire stratified water body, a carried water quality multi-parameter analyzer (YSI, USA) is simultaneously used to complete real-time observation of a specific water depth and an entire vertical-profile water body, and to transmit monitoring data to a water surface operating system in real time.

[0036] When the sampling device main chamber 1 is about 100 cm away from the surface of a sediment, the propeller 3 is remotely driven by water operation, and then the attitude balance sensing device of the sampling device namely the attitude balance sensor 2 is used to guide the sampling device to a substantially balanced state. An underwater high-definition camera of the illumination camera system 10 is mainly mounted at front and rear ends of the sampler body and a vector downward position. A water operation panel is used to analyze underwater topography and substrate types, and provides an intuitive high-definition evidence to select an optimal sampling point. When the sampling point is not suitable for the operation, the propeller 3 is triggered by operating a remote control to adjust the position of the entire sampling device, and then the fine attitude adjustment of the entire sampling device is realized by adjusting the attitude balance sensor 2 on the sampling device, thereby obtaining an optimal sampling point.

[0037] After the sampling device base falls stably to the surface of a substrate to be collected, the downward pressure of the sampling device is further increased by adjusting the buoyancy of the sealed cabin, thus providing a stable supporting role for the collection of a sediment core.

[0038] The high frequency vibration sensor is remotely controlled to slowly push the sampling tube of the array type sediment collector to move down and gradually contacts the surface of the sediment. A low-speed rotary sampling drill mode is initially used to make the sampling tube enter the sediment without disturbance. After entering the surface sediment for 3 to 5 cm, the sampling tube is pushed into the sediment by a high-speed vibration mode.

[0039] After the array type sediment collector completes sediment sampling, the sampling tube is gradually separated from the sediment by adjusting the high frequency vibration sensor, and the sampling device main chamber is maintained in equilibrium by the safety umbilical cord, the propeller 3 and the attitude balance sensing device 2.

[0040] The entire underwater sampling device is recovered at a constant speed through the safety umbilical cord, the multi-channel array type water collector and sediment collector are manually removed, and auxiliary components such as an accurate sediment cutting device and an anaerobic glove box are used to obtain in-situ complete stratified water samples and sediment core samples. The entire sampling process is completed so far.
