Abstract

PROBLEM TO BE SOLVED: To save the labor and reduce the time for sampling sea-bed mud and to improve the accuracy for sampling a sea-bed organism (benthos). SOLUTION: The device comprises four portions, namely a sea-bed mud suction equipment 1, a mud separation/benthos automatic screening equipment 3, a sea-bed mud-carrying equipment 2, and a drive power equipment. Also, the device is provided with a device for automatically adjusting the flow rate where the sea-bed mud suction equipment 1 is checked by a posture stability instruction equipment 10 for the levelness at a sea-bed arrival point, the mud separation/benthos automatic screening equipment performs screening by the shower of seawater, and the sea-bed mud-carrying equipment 3 detects the fluid flow rate in a hose with a flowmeter, and the drive power equipment has an automatic flow rate controller 6 which is automatically adjusts the flow rate being detected by the flowmeter to a preset value in advance. The seabed mud automatic sampling device reduces the fatigue of operation as compared with the mud-sampling method that has been performed by human power conventionally, the scattering of the sampling rate of mud is reduced and the sampling rate is improved, and the sampling time of the benthos can be drastically reduced due to the seawater shower system, and the sampled mud cannot be allowed to flow to the sea due to a completely sealed container when screening the benthos.

2. Description of the Related Art Conventionally, for collecting seabed mud for the purpose of investigating marine pollution, a grab collecting device such as an Ekman barge type is generally used. However, in this method, the grab sampler is dropped from the ship to the seabed, and the grab is closed by a spring method to collect the mud. Since the work is performed manually, the degree of fatigue of the work and the success rate of the mud sampling (per sampling time) There is a problem with the variation in the amount of mud), and in the case of collecting benthic organisms (benthos), it takes a long time to sift by hand and the mud collected at the time of sieving together with bentos There is a problem that there is a loss of flowing into the sea and there is a problem.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, 1 is a submarine mud suction device, 2 is a submarine mud transporter, 3 is an automatic sieve for separating muds and vents, 4 is an air compressor, 5 is an air piping hose, 6 is an automatic flow control device, Reference numeral 7 denotes a stainless mesh, which sucks mud and seawater from the bottom mud layer 14, discharges seawater from the seawater outlet 20, removes mud from the mud outlet 21, and removes vents remaining on the stainless mesh 7. FIG. 1 is a diagram illustrating an entire apparatus having a series of functions for collecting data. FIGS. 2 and 3 show the structure of the submarine mud suction device.
With 8 submarine mud suction pipes, submarine mud can be sucked by the compressed air blown out from the 23 compressed air blowing section. Also, the horizontality of the seabed mud suction skirt is confirmed by the 8 attitude sensor, 9 sensor wire cable and 10 attitude stability indicating device, and thereby the attitude is controlled by the rope. Fig. 4 and Fig. 5 show the structure of the automatic mud separation / vents sieve, and the bottom mud sucked from the 14 bottom mud layer is transported to the 3 automatic mud separation / vents sieve by the 2 subsea mud transporter. If you want to collect a mixture of mud and seawater, and only the mud, remove 7 stainless steel mesh, open a valve at 20 seawater discharge port to discharge only seawater and leave mud. If it is desired to collect only bentos, a 7 stainless steel mesh can be installed, seawater can be discharged from 20 seawater outlets, and bentos can be left on the 7 stainless steel mesh. At this time, by shortening the seawater from the top of the sieve, the time required for the automatic vents sieve operation can be reduced.
