Background
In the process of dredging and loading, the characteristics of the slurry such as the type, the concentration and the like of the drag suction ship can directly reflect the construction efficiency and the quality. Especially for the condition that construction efficiency suddenly changes, mud sampling is timely carried out, and the method is very important for analyzing the reasons for the sudden change of efficiency and improving the optimization process.
For a trailing suction hopper dredger, the sampling location is typically located near the energy dissipating tank and overflow drum of the mud hold. At present, sampling personnel on a ship usually stand on one side of a mud cabin deck, and a sampling tube is lowered to a mud outflow port of an energy dissipation box and an overflow tube through a rope to perform sampling operation. Such modes of operation mainly suffer from the following disadvantages:
(1) Because the slurry flow rate of the slurry outlet is larger, the sampling tube which is lowered to the proper position is always nearly full in 1-3 seconds, and the slurry with lower concentration at the upper layer in the sampling tube can splash out of the sampling tube due to shaking of the sampling tube and overlarge flow rate, the concentration is higher and sediment is left in the sampling tube, so that the concentration of the slurry which is actually taken is larger, and particularly for coarse particle soil which is easy to precipitate quickly, the sampling concentration error is larger;
(2) The closest horizontal distance of the tank and the overflow bowl to the deck of the mud hold remains far, which is a safety risk for the sampling personnel to manually lower the bowl with a rope, and the bowl tends to fill up very nearly in a very short period of time, which means that the sampling personnel will be subjected to a large force in a very short time, which is a great challenge for safe operation.

the two telescopic mechanisms are symmetrically connected with the two ends of the outer sleeve 11 of the driving mechanism;
each telescopic mechanism comprises a loop bar 15 and a telescopic bar 16 arranged in the loop bar 15; wherein the outer diameter of the sleeve rod 15 is smaller than the outer diameter of the outer sleeve 11; the telescopic rod 16 comprises an inner tube 161, a screw rod 162, a sliding block 163, a spring 164 and a sucker 165; the inner tube 161 is coaxially and slidably arranged in the inner cavity of the loop bar 15, the inner tube 161 is provided with a front sealing plate, and a plurality of sliding grooves 166 are uniformly distributed on the inner wall surface of the rear part of the inner tube 161 in the axial direction; the screw rod 162 is arranged in the inner cavity of the inner tube 161, the rear end of the screw rod 162 is connected with the front end of the coupler 14, and the front end of the screw rod 162 is rotatably connected to the front sealing plate of the inner tube 161 through an inner rod 167; the sliding block 163 is arranged on the screw rod 162 in a threaded manner, and a plurality of protruding edges which are embedded with a plurality of sliding grooves 166 on the inner pipe 161 one by one are uniformly distributed on the outer wall surface of the sliding block 163; the spring 164 is provided between the front end face of the slider 163 and the rear end face of the front seal plate of the inner tube 161; suction cups 165 are mounted on the front face of the front closure plate of the inner tube 161.
The loop bars 15 of the two telescopic mechanisms 1 are symmetrically welded with a hanging ring 17.
The sampling mechanism 2 comprises a waterwheel type wheel disc 20, a ball bearing 23, a plurality of supporting rods 24 and a plurality of sampling barrels 25; the waterwheel type wheel disc 20 comprises two parallel running frames 21, two rims 22 fixed at the outer ends of the two running frames 21 in a one-to-one correspondence manner and a shaft sleeve connected between the centers of the two running frames 21; the ball bearing 23 is mounted in the sleeve; the support rods 24 are horizontally and uniformly connected between the outer end surfaces of the two rims 22; the sampling barrels 25 are installed in the middle of the supporting rods 24 in a one-to-one correspondence.
The outer sleeve 11 of the electric telescopic rod 1 is inserted into an inner hole of the ball bearing 23 of the sampling mechanism 2, and the sampling mechanism 2 is fixed in the middle of the outer sleeve 11 through two buckles 10;
according to the mud sampling device for the trailing suction hopper, the mud sampling device can be fixed on two side walls of a mud cabin under the action of the springs 164 of the two telescopic mechanisms of the electric telescopic rod 1 and provides support for the sampling mechanism 2; when the double-shaft motor 12 in the driving mechanism of the electric telescopic rod 1 drives the screw rods 162 in the two telescopic mechanisms to rotate through the speed reducer 13 and the coupler 14, the sliding block 163 arranged on the screw rods 162 is driven to move along the axial direction of the screw rods 162 and drive the inner tube 161 to stretch to a required position, the strong suction cups 165 arranged at the front end of the inner tube 161 are adsorbed on two side walls of a mud cabin, and the angles of the strong suction cups 165 are adjustable and can be suitable for the side walls of the mud cabin of different trailing suction boats. The spring 164 can bear against the inner tube 161, thereby realizing that the inner tube 161 extends out of the loop bar 15; because the trailing suction hopper ship encounters larger surge during open sea construction, the shaking of the ship can apply sudden pressure to the telescopic rod 16; when the telescopic rod 16 is suddenly stressed, the spring 164 is compressed, and the sliding block 163 slides in the sliding groove 166 of the inner tube, so that a certain buffering function is realized, and the telescopic rod 16 can be prevented from being damaged.

The two buckles 10 on the outer sleeve 11 of the electric telescopic rod 1 can prevent the sampling barrel 25 of the sampling mechanism 2 from being offset and damaged due to overlarge flow of slurry when the mud cabin receives the slurry at the outlet.
After the installation of the whole sampling device is completed, the sampling mechanism 2 is positioned at the position of the flow outlet of the trailing suction hopper, slurry can impact to the waterwheel disc when flowing out from the flow outlet, and the slurry enters the sampling barrel 25, the whole sampling mechanism 2 can rotate under the action of gravity and the impact force of the slurry by means of the ball bearings 23 until each sampling barrel 25 is filled with the slurry, and then the telescopic rod 16 is contracted by means of the double-shaft motor 12, so that the sampling mechanism 2 is taken down and the slurry sample in the sampling barrel 25 is poured out, and the whole sampling operation is completed.
When the sampling device is installed on the large-scale trailing suction hopper ship, the whole sampling device is difficult to control only by manpower due to large size and weight, lifting equipment on the ship can be used for lifting after being connected with lifting rings 17 on loop bars 15 of two telescopic mechanisms 1 through steel wire ropes 18 with the lifting rings, and the installation of the whole sampling device is completed under the assistance of manpower.
The electric telescopic rod 1 can be matched with sampling mechanisms 2 with different sizes, and can meet the sampling requirements of drag suction boats with different types. The waterwheel type wheel disc 20 can be matched with sampling barrels 25 with different sizes, and can meet the requirements of different sampling amounts.
