The monitoring unit includes detector and display, the rasping unit includes grasp bucket and its driver, and the central control unit receives the signal from the monitoring unit and controls the action of the grasping unit. The sampling process includes the following steps: hanging the grasping unit into water with cable, powering the video camera, sensor and lighter and monitoring in the display, observing underwater state and searching target, grasping target, hoisting and opening the grasp bucket in the deck. The present invention is intuitive, can grasp required mineral selectively and has high sampling accuracy and efficiency.
Description
Technical field
The invention belongs to sampling apparatus and method, relate in particular to a kind of method of sampling under water that is used for sampling apparatus under water and utilizes this device.
Background technology
In order to obtain under water sample ore, to understand under water geological condition and study, people normally adopt " trawlnet " device, promptly drag trailer with ship and walk under water, and sample ore shovels into trailer under water, slings to the boat deck then.But this method and apparatus is because poor accuracy is difficult to shortcomings such as control, and its effect is very undesirable.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, provide a kind of can observation water under sample ore sampling apparatus under water and utilize the method for sampling under water of this device.
For achieving the above object, it comprises central control unit, monitoring device and grabbing device, central control unit is connected by lead with grabbing device with monitoring device, wherein monitoring device comprises sniffer and display device, grabbing device comprises grab bucket and drive unit thereof, and central control unit receives the signal of monitoring device and controls the action of grabbing device.
Above-mentioned sniffer is arranged on the grabbing device, and it comprises sensing device, camera head and lighting device; Sensing device comprises the sensor that can measure the grabbing device state that is arranged on the grabbing device; Grab bucket comprises bearing and jaw, and main hydraulic cylinder is set on the bearing, and a side and the bearing of jaw are hinged, and the output terminal of opposite side and main hydraulic cylinder is hinged; Drive unit comprises electrokinetic cell and fluid pressure drive device.
The invention still further relates to a kind of method of sampling under water of utilizing above-mentioned sampling apparatus under water, comprised the steps:
(1) by hawser water is put in the grabbing device lifting on the deck;
(2) open camera head, sensing device and lighting device by control device, and on display device, monitor transducing signal and observe water-bed situation and searching target;
(3) make grab bucket grasp target by control device, drive unit;
(4) lifting is opened grab bucket to the deck.
Comprise in the step (1) when grabbing device arrives the water-bed certain distance of distance, start sensing device; When step (1) comprises grabbing device near the bottom, start camera head and lighting device; Step (3) comprises that grabbing device moves and observes at approaching place, after grasping movement finishes, lifts by crane after truly having object in the camera head affirmation grab bucket; Before comprising that grabbing device hangs out the water surface in the step (4), close sensing device, lighting device and camera head.
Adopted said method and device, owing to have a camera head, can Direct observation and ferret out thing, grasp required sample ore selectively, improved the accuracy rate and the operating efficiency of sampling greatly.
Description of drawings
Fig. 1 is the present invention's sampling apparatus synoptic diagram under water.
Embodiment
The present invention is for effectively obtaining the sampling apparatus under water that sample ore is under water developed, it is based on visual pattern observation and power-actuated grabbing device, its principle is that the underwater camera device that at first carries by grabbing device is observed the distribution situation of geology and sample ore under water in detail, then controlling and driving underwater power pack is above deck realized the effective collection of machinery grab bucket to the sample ore object.
As shown in Figure 1, the present invention's sampling apparatus under water mainly comprises central control unit, monitoring device and grabbing device, central control unit is connected by concentric cable with grabbing device with monitoring device, wherein monitoring device comprises sniffer and display device, sniffer comprises sensing device, camera head and lighting device, and grabbing device comprises grab bucket and drive unit thereof; Central control unit and display device are positioned on the deck when work, monitoring device and grabbing device are lifted in the water by hawser, concentric cable in the hawser has the effect of transmitting signal, the state of grabbing device, can be delivered on the display device by hawser as height, jaw folding, inclination angle etc., people can observe and monitor the situation of grabbing device itself; Simultaneously, the image of camera head picked-up also is delivered on the display device by hawser, and people observe situation, ferret out thing under water by it; Based on above-mentioned Monitoring Data, people control the startup of monitoring device by central control unit and close, and pass through the action of the driving device controls grabbing device of grabbing device.
The probe of grabbing device and drive unit thereof and sensing device, camera head, lighting device are made into one physically, drive unit is a hydraulic-driven, be convenient to operation and withstand voltage, the grab bucket of grabbing device comprises bearing and jaw, main hydraulic cylinder is set on the bearing, one side and the bearing of jaw are hinged, and the output terminal of opposite side and main hydraulic cylinder is hinged; Drive unit comprises electrokinetic cell and fluid pressure drive device.
Sensing device comprises some sensors, can measure height, inclination angle, displacement, voltage, electric current, hydraulic pressure, cable tension of grabbing device etc.
Utilize device of the present invention to adopt as shown in Figure 2 flow process and method to sample under water:
Grabbing device and monitoring device are lifted, start central control unit, and the jaw of will grabbing bucket places open configuration;
When grabbing device arrives the water-bed certain distance of distance, start sensing device;
When device detects grabbing device near the bottom, start camera head and lighting device by central control unit, observe and search;
After finding object, drive hydraulic means control by central control unit and grasp; Transducing signal and the image pickup signal observed on the display device monitor the extracting process.
Grabbing device is moving and is observing near place, the bottom, after grasping movement finishes, lifts by crane after truly having object in the camera head affirmation grab bucket, as the driftlessness thing, searches for again and grasps; In case of necessity, repeat search and grasp step repeatedly;
Before grabbing device hangs out the water surface, close sensing device, lighting device and camera head.
After confirming that object is arranged, the boom hoisting on the deck lifts by crane, and grabs bucket to the deck and opens, and takes off object.
The present invention can be used for taking of rivers,lakes and seas substrate geological sample, is particularly useful for abyssalbenthic sampling.
From the above, adopt sampling apparatus under water of the present invention and method, owing to have a camera head, can Direct observation and ferret out thing, grasp required sample ore selectively, improved the accuracy rate and the operating efficiency of sampling greatly.
