Embodiment Construction

[0012] like figure 1 Shown is the structural representation of the present invention.

[0013] Knife barrel parts: including a hand-held rod 1, an upper end cover 3, a knife barrel 7, and a socket 10; There is a step-shaped insertion tube 10, and the large cylindrical surface of the insertion tube 10 is tightly matched with the hole in the lower part of the knife cylinder 7 and is fastened with screws, and the small cylindrical surface of the insertion tube 10 and the knife cylinder 7 keep a gap.

[0014] Knife cylinder 7 tops are connected with upper end cover 3 with screw thread, and T-shaped hand-held bar 1 is connected with upper end cover 3 by lock nut 2, is convenient to manipulator operation. The bottom of the cutter cylinder 7 is connected with the inserting sleeve 10 with screws, and this structure can make the plum petals 9.1 in the lining sleeve 8 fully open before sampling (such as figure 2 shown), the sample is closed and cut off after sampling (such as image...

Abstract

A mechanical handheld type deposit sampler consists of a knife pot assembly and a bush assembly. The knife pot assembly includes the hand bar, the upper end cover, the knife pot and the inserting tube. The bush assembly installed in the knife pot assembly includes the brush cover, the filter screen and the bush, and the claw petal. The manipulator grasping the T type hand bar inserts the sampler down into the marine deposits vertically. In the inserting procedure, the seawater through the filter screen and the drain hole is discharged outside. With the deposit touching the cover of the bush, the bush is brought to move upwards. When the cover touching the locknut, the claw petal is closed to cut off the deposit, sealing the opening so as to complete the sampling operation.

Description

technical field [0001] The invention relates to a mechanical hand-held sediment sampler without boundary disturbance. Background technique [0002] Determining the chemical state of deep seabed hydrothermal fluids and sediments, as well as the content changes of dissolved components in hydrothermal fluids, is one of the main tasks of marine resource and environmental exploration, and is also a basic means of oceanographic research. Restricted by sampling conditions, the current marine resources exploration in my country can only use the traditional sampling method, that is, to put samplers from ships at sea, collect a large number of hydrothermal and seabed sediment samples at different positions and depths in a wide range, and return them to the seabed. After arriving in the laboratory, the sample is analyzed for the content of chemically dissolved components. Such a lack of accurate sampling often wastes a lot of manpower and material resources, an...
