Description
Technical field
The present invention relates to detection technique field, a kind of thing position, relate in particular 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 positions such as rock stratum to seabed or liquid material present position, pond, oil tank, in order to grasp the material degree of depth or confirm that whether detector touches at the end, perhaps judges seabed depth in ocean operation.After sensor entered liquid material, whether the GPRS sensor arrived the bottom of liquid material, because the complicacy of liquid material, touched end state and was not easy so that detect accurately in a lot of situations.As in the process of oil exploitation, what collect is potpourri by crude oil, water, sediment composition, and after potpourri is injected into storage tank, the medium in the storage tank will separate gradually and form air, former oil reservoir, pure water layer, silt layer, and wherein the silt layer usually can be in the bottom.After the suspension type sensor for detection of medium drops to tank bottom, touch end signal as can not in time producing, twining might appear in the outstanding rope that continues to descend, and cause around the cable accident.
For above-mentioned situation, current commonly used be to utilize medium sensor to detect, on the basis of detecting sensor place medium medium dielectric constant microwave medium, specific inductive capacity jumping phenomenon when utilizing sensor to arrive the bottom confirms to arrive bottom signal.This detection method only is adapted to have the situation of differing dielectric constant layer liquid material, and in the situation that the tactile end also can produce the phenomenon of specific inductive capacity sudden change, causes the tactile end to measure inaccurate.Prior art can also be utilized acceleration transducer to measure and touch end state, but simple acceleration transducer relatively is suitable for using under the little medium of the such viscosity of similar water and the hard bottom state, can obtain reliable measuring state, but in the situation that liquid material viscosity is large or the bottom is soft, because the impact that sensor is experienced is little, mistake then easily occurs and survey wrong report, and the soft beds of precipitation can appear in the bottom of generic container, and 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, pick-up unit of a kind of tactile end is provided, it can accurate, sensitive measuring touch end state in various liquid mediums.

The invention has the beneficial effects as follows: owing to having adopted secondary impact mechanism, so that the lower end of sensor module can hit with the hard hit of described secondary impact winding machine, thereby obtain clear and definite jump signal, accurately be confirmed whether to touch at the end.And then discharged because material viscosity, change in dielectric constant, or the disturbing factor that factor brings such as the 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 the upper end is inserted in the described slideway.
Adopt the beneficial effect of above-mentioned further scheme to be, its simple in structure, reliable operation of this slide bar slideway structure.
Further, also comprise the 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 the described slideway.
Adopt the beneficial effect of above-mentioned further scheme to be, set up the sensor module support can be more convenient and described combination or the fractionation of secondary impact mechanism.
Further, the described sensor that detects bump is acceleration transducer.
Adopt the beneficial effect of above-mentioned further scheme to be, acceleration transducer is more satisfactory a kind of, and specific inductive capacity and outside electromagnetic interference that it is not subjected to material are quick on the draw.
Further, described sensor module comprises that also the specific inductive capacity sensor that is combined with described groups of acceleration sensors, temperature sensor, pressure transducer are or/and Ph value sensor.
Adopt the beneficial effect of above-mentioned further scheme to be, adopt the sensor of multi-functional combination can reduce testing cost, be convenient to signal and focus on.
Further, described secondary impact mechanism is stainless steel.
Adopt the beneficial effect of above-mentioned further scheme to be, stainless steel is corrosion-resistant, and has larger proportion, can touch that the end keeps during state and sensor module between the distance of secondary impact.

Embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used for explaining the present invention, is not be used to limiting scope of the present invention.
Such as Fig. 1 and shown in Figure 5, pick-up unit of a kind of tactile end comprises sensor module 1, and the bottom of described sensor module 1 is set with the secondary impact mechanism that can slide along the axis of described sensor module 1, and described sensor module 1 comprises the sensor that can detect bump.
Described secondary impact mechanism comprises impact member 4 and at least two slide bars 2, and the outside of described sensor module 1 is provided with the slideway 3 suitable with described slide bar 2, and the lower end of described slide bar 2 is fixedly connected with described impact member 4, and the upper end is inserted in the described slideway 3.
The described sensor that detects bump is acceleration transducer.
Described sensor module 1 comprises that also the specific inductive capacity sensor that is combined with described groups of acceleration sensors, temperature sensor, pressure transducer are or/and Ph value sensor.
Described secondary impact mechanism is stainless steel.
Arrive shown in Figure 5 such as Fig. 2, another embodiment of the present invention, what all the other embodiment 1 were different is: pick-up unit of a kind of tactile end, also comprise sensor module support 5, the top of described sensor module support 5 is fixedly connected with the bottom of described sensor module 1, the outside of described sensor module support 5 is provided with the slideway 3 suitable with described slide bar 2, and described slide bar 2 is inserted in the described slideway 3.
All the other are identical with embodiment 1, repeat no more.
The principle of work of the present embodiment is as follows: after the present invention is put into liquid material, at the uniform velocity fall by draught line, when the present invention suspended in normal descend or in liquid state, secondary impact mechanism was hung in the lower end of described sensor module support by the gravity cunning, and both keep hanging and connect; When this assembly slides into container bottom at the uniform velocity down, at first be that collide for the first time secondary impact mechanism and bottom, the contact bottom stops to move ahead, and sensor module and sensor module support continue descending along inertia, and the impact member generation hard hit in secondary impact mechanism is hit, so that sensor obtains violent impact signal, touch end signal thereby send.Form of this tactile end, thoroughly avoided because at the bottom of the pond, at the bottom of the tank, the soft measurements interference that brings in seabed or oil reservoir bottom, end situation is touched in grasp that can be definite.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
