Description
Technical Field
The invention relates to the technical field of underwater sediment sampling, in particular to a device for vertically putting a sediment sampler.
Background
The columnar samples of the sediments in the deep lake reservoir are mainly collected by a plexiglass tube with an inner diameter of 54mm and a sampler (the sampler with the application number of CN 200520000502.0), and the sampler needs to be inserted into the collected sediments and kept for 24 hours to achieve the effect of in-situ measurement. Because the organic glass for storing the sediment has thin pipe diameter and long length, the sampler is easy to deflect in the manual feeding process of the sampler, the measurement fails, and the sampling efficiency and quality are reduced.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a device for vertically putting a sediment sampler, which solves the problem that the sampler is easy to deflect in the putting process in the prior art.
In order to achieve the purpose of the invention, the technical scheme adopted by the invention is as follows:
the utility model provides a make device that sediment sample thief was put in perpendicularly which includes the guide cylinder, and the bottom of guide cylinder is fixed with rightting mechanism, and the top of guide cylinder is provided with pushes down handle and spirit level, and threaded connection has the boosting pipe in the hole on guide cylinder upper portion. The bottom of guide cylinder is the horn mouth, and the mechanism of righting includes the tripod fixed with the guide cylinder and fixes on the tripod and lean out three or more landing legs.
Further, the bottom end of the supporting leg is provided with a conical head. The supporting legs can be conveniently inserted into the underwater bottom mud deeper through the conical heads, and stability is improved.

The hollow structure of the support legs helps to reduce the weight, facilitate transportation and handling and assembly at a sampling site; the weight of the righting mechanism can be increased by introducing water at the sampling position into the inner cavity of the supporting leg through the water inlet, and the stability in the sediment is improved.
Furthermore, the tripod is provided with a through hole which is not smaller than the opening at the bottom end of the guide cylinder. The upper part of the sampler can be conveniently inserted into the guide cylinder for fixing through the through hole.
Further, the guide cylinder comprises an inner pipe and an outer pipe which are overlapped, an interlayer cavity is formed between the inner pipe and the outer pipe, the top end and the bottom end of the interlayer cavity are sealed, and a communication hole which is communicated with the interlayer cavity is formed in the outer pipe. The setting in intermediate layer chamber is in order to alleviate the weight of guide cylinder, is convenient for carry and assemble in the field, and the intercommunicating pore makes hydroenergy enough get into the bottom in intermediate layer chamber, reduces the focus of guide cylinder, improves the steadiness.
Further, a plurality of communication holes are provided in the middle and lower portion of the outer tube.
Furthermore, the inner wall of the small-diameter end of the bell mouth is embedded with a rubber ring, and the inner wall surface of the rubber ring is higher than the inner wall surface of the small-diameter end of the bell mouth. Avoid the sample thief to be hard contact when inserting into the guide cylinder from the horn mouth through the rubber circle, reduce wearing and tearing, increase the frictional force of contact surface, it is more firm to fix.
Furthermore, the handle is pressed down for two arc lugs that the symmetry is fixed in the guide cylinder outer wall, all is provided with a spirit level on every arc lug. The arc-shaped lugs are convenient for an operator to hold, the gradienters which are symmetrically arranged are convenient for observing the vertical degree of the guide cylinder in real time and adjusting the vertical degree in real time in the pressing process, the verticality of the guide cylinder is improved, the verticality of the sampler is further improved, and the inclination is prevented.
Furthermore, an opening penetrating along the axial direction is arranged on the side wall of the boosting pipe. The upper connecting rod at the top end of the sampler can pass through the opening conveniently, and the nylon rope is connected to the upper connecting rod, so that the boosting pipe is prevented from being sleeved from the end part of the nylon rope, and the convenience in field installation is improved.
Furthermore, the top of the boosting pipe is provided with a rotating handle. The rotation process is more labor-saving by rotating the handle, the boosting tube is moved downwards relative to the guide cylinder by rotating the boosting tube, and the sampler clamped at the bell-mouthed end is pushed to be separated from the guide cylinder.
The invention has the beneficial effects that: the horn mouth that the guide cylinder bottom set up is convenient for the sample thief to insert and coaxial fixed, can real-time supervision through the spirit level impress the guide cylinder into the horizontal degree of the underwater bed mud in-process guide cylinder terminal surface, and then control the axial straightness that hangs down of guide cylinder through real-time adjustment, and then guarantee that the sample thief is not crooked at the input in-process.
After the sampler is successfully put in, the sampler can be pushed to be separated from the guide cylinder through the boosting pipe, and the boosting pipe is in threaded connection with the guide cylinder, so that the boosting pipe can be fixed at any position and does not retreat in the pushing-down process, the requirement on the continuity of operation is lowered, and the sampler is labor-saving and convenient.
The righting mechanism that the guide cylinder bottom set up can insert this device in the bed mud of the scarcity under water and stable support, and many long and thin landing legs can reduce and insert the resistance, make this device insert in the bed mud more easily.
Guide cylinder and righting mechanism all adopt inside hollow structure, reduce the weight of self to reduce the transport and the installation burden of this device of using in the field, through submerging the aquatic back, water enters into inside hollow structure and reduces the focus, utilizes this device to be the characteristics of using in the water environment ingeniously, has improved the convenience in use of this device.
