Description
Technical field
The present invention relates to a kind of Level measurement technical field, particularly relate to pick-up unit of a kind of tactile end.
Background technology
In commercial production, exploitation of oil-gas field and ocean operation, often relate to the detection of the bottom position such as rock stratum, pond, oil tank to seabed or liquid material present position, to grasp material depth or to confirm that whether detector touches the end, or judge seabed depth in ocean operation.After sensor enters liquid material, whether GPRS sensor arrives the bottom of liquid material, due to the complicacy of liquid material in a lot of situation, makes detect state of the tactile end accurately and be not easy.As in the process of oil exploitation, the potpourri be made up of crude oil, water, silt collected, after potpourri is injected into storage tank, the medium in storage tank will be separated gradually and form air, crude oil layer, pure water layer, silt layer, and wherein silt layer usually can in bottom.After the suspension type sensor for detecting medium drops to tank bottom, as do not produced signal of the tactile end in time, being wound around will likely appear in the outstanding rope continuing to decline, and cause around cable accident.
For above-mentioned situation, current conventional be utilize medium sensor to detect, on the basis of detecting sensor place medium medium dielectric constant microwave medium, when utilizing sensor to arrive bottom, specific inductive capacity jumping phenomenon, confirms to arrive bottom signal.This detection method is only adapted to the situation with differing dielectric constant layer liquid material, and when not touching the end, also can produce the phenomenon of specific inductive capacity sudden change, causes the tactile end to measure inaccurate.Prior art can also utilize acceleration transducer to measure state of the tactile end, but simple acceleration transducer compare be suitable for the little medium of the such viscosity of similar water and hard bottom state under use, reliable measuring state can be obtained, but when liquid material viscosity is large or bottom is soft, the impact experienced due to sensor is little, then easily appearance surveys wrong report by mistake, and the bottom of generic container there will be the soft beds of precipitation, therefore common acceleration transducer is difficult to Accurate Determining and touches end reaction.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of and touch end pick-up unit, it accurate, sensitively in various liquid medium can measure state of the tactile end.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: pick-up unit of a kind of tactile end, comprise sensor module, it is characterized in that, the bottom of described sensor module is set with can along the secondary impact mechanism of the axial sliding movement of described sensor module, and described sensor module comprises the sensor that can detect shock.
The invention has the beneficial effects as follows: owing to have employed secondary impact mechanism, make the lower end of sensor module can realize hard hit with described secondary impact mechanism and hit, thus obtain clear and definite jump signal, be accurately confirmed whether the tactile end.And then discharged due to material viscosity, change in dielectric constant, or the disturbing factor that factor brings such as bottom is soft.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described secondary impact mechanism comprises impact member and at least two slide bars, and the outside of described sensor module is provided with the slideway suitable with described slide bar, and the lower end of described slide bar is fixedly connected with described impact member, and upper end is inserted in described slideway.
The beneficial effect of above-mentioned further scheme is adopted to be that this its structure of slide bar slideway structure is simple, reliable operation.
Further, also comprise sensor module support, the top of described sensor module support is fixedly connected with the bottom of described sensor module, and the outside of described sensor module support is provided with the slideway suitable with described slide bar, and described slide bar is inserted in described slideway.
Adopt the beneficial effect of above-mentioned further scheme to be, setting up sensor module support can the combination of more convenient and described secondary impact mechanism or fractionation.
Further, the described sensor detecting shock is acceleration transducer.
Adopt the beneficial effect of above-mentioned further scheme to be that acceleration transducer is more satisfactory one, it by specific inductive capacity and the outside electromagnetic interference of material, is not quick on the draw.
Further, described sensor module also comprise be combined with described groups of acceleration sensors dielectric constant sensor, temperature sensor, pressure transducer is or/and Ph value sensor.
The beneficial effect of above-mentioned further scheme is adopted to be adopt the sensor of multifunctional combination to reduce testing cost, be convenient to signal and focus on.
Further, described secondary impact mechanism is stainless steel.
The beneficial effect adopting above-mentioned further scheme is that stainless steel is corrosion-resistant, and has larger proportion, can keep the distance of secondary impact between sensor module when tactile end state.

Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment 1
As shown in Figure 1 and Figure 5, pick-up unit of a kind of tactile end, comprise sensor module 1, the bottom of described sensor module 1 is set with can along the secondary impact mechanism of the axial sliding movement of described sensor module 1, and described sensor module 1 comprises the sensor that can detect shock.
