Abstract
The utility model discloses a rare soft substrate shear strength normal position tester in deep sea, including sleeve, cross plate, fix the axostylus axostyle on the cross plate and form the upper and lower end cover of enclosure with the sleeve, still include one and fix the vulcanization socket that is used for the circular telegram on the upper end cover, there is a torque sensor in the telescopic enclosure, the torque sensor upper end passes through the wire electricity with the vulcanization socket and is connected, and the lower extreme is connected with the axostylus axostyle. The utility model discloses an adopt torque sensor to measure, the low price, simple structure, the measuring accuracy is high.
Description
Technical field
The utility model relates to a kind of deep-sea rare softground shear resistance in-situ test instrument, is used for the shear resistance on-the-spot test of the rare softground in deep-sea, belongs to marine resources development exploration equipment manufacturing technology field.
Background technology
Accurately obtain the mechanical property parameter of the rare softground of deep-sea floor, very important meaning is arranged for seabed engineering construction, the design of seabed operation vehicle and geological sciences research etc.Shear resistance is as an important parameter in the mechanical property parameter of rare softground, and direct relation the reliable construction of seabed engineering and the science design of seabed operation vehicle.Patent ZL2008200531119 has announced a kind of novel deep sea sediment shear resistance in-situ test instrument, and the shearing force that four-bladed vane is subjected to acts on the in-oil cylinder hydraulic oil of sealing through cross-bar, obtains the shear resistance of rare softground by pressure transducer.It is curved that the used hydraulic tube of this tester is 90 folding degree, and crushing is big, has reduced the measuring accuracy of instrument, complicated integral structure.In addition, high and low pressure side can be born the differential pressure type product sensor rareness of 60MPa, and price is very expensive.
The utility model content
The purpose of this utility model is to provide a kind of deep-sea cheap, simple in structure, that measuring accuracy is high rare softground shear resistance in-situ test instrument.
This deep-sea rare softground shear resistance in-situ test instrument that the utility model provides, comprise sleeve, four-bladed vane, be fixed on the axostylus axostyle on the four-bladed vane and form the upper and lower end cap of enclosure space with sleeve, comprise that also one is fixed on and is used to the sulfuration socket of switching on the upper end cover, a torque sensor is arranged in the enclosure space of described sleeve, described torque sensor upper end is electrically connected by lead with the sulfuration socket, and the lower end is connected with axostylus axostyle.
The lower end of described upper end cover is fixed with a flange, and the lower end of described flange is connected with torque sensor, and the upper end is connected with the sulfuration socket, and the hole that the lead of described sulfuration socket passes flange center is electrically connected with torque sensor.
This employing torque sensor of the present utility model is measured, and is cheap, simple in structure, the measuring accuracy height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As can be seen from Figure 1, this deep-sea of the present utility model rare softground shear resistance in-situ test instrument, comprise sleeve 1, four-bladed vane 2, be fixed on the four-bladed vane 2 axostylus axostyle 3 and last, bottom end cover, wherein axostylus axostyle 3 is integrally welded with four-bladed vane 2, upper end cover 6 and bottom end cover 7 by screw retention at sleeve 1 two ends, form the space of sealing with sleeve 1, the lower end of described upper end cover 6 is fixed with a flange 8, the hole is opened at the center, there is a sulfuration socket 4 that is used to switch on to be connected by the threaded hole of screw thread with upper end cover 6 centers, a torque sensor 5 is arranged in the enclosure space of sleeve 1, and described torque sensor 5 upper ends are connected with flange 8, and the lower end is connected with axostylus axostyle 3.Respectively there are four electrodes the upper and lower of described sulfuration socket 4, and upper electrode is connected with weather proof receptacle, and the hole that the lead 9 of lower electrode passes flange 8 centers is electrically connected with torque sensor 5.
In the time of installation process of the present utility model, to vulcanize socket earlier and be fixed on upper end cover top by screw thread, lead connects the lower electrode and the torque sensor of upper end cover, torque sensor is connected with the flange lower thread, flange by screw retention in the upper end cover lower end, upper end cover and bottom end cover are pressed into the sleeve two ends respectively, and axostylus axostyle screws in the torque sensor lower end from the bottom end cover central through hole and is threaded, and seal by the O RunddichtringO between upper end cover and bottom end cover and sleeve, bottom end cover and axostylus axostyle.The utility model injection substrate and shear substrate under mechanical effect, four-bladed vane is subjected to the shearing resistance effect of substrate, shearing force is converted into moment of torsion exports through torque sensor, through obtaining the shear resistance of the rare softground in deep-sea after the data processing.
