Abstract
An expending device of an underground testing probe is characterized in that the upper part of the probe is articulated with an elastic rod with magnetic material; a compressed spring is arranged between the elastic rod and the probe body which is provided with an electromagnet adsorbing the elastic rod. The elastic rod after adsorbed can be flatly attached to the side surface of the probe body. The elastic rod is released by the electromagnet, saving the gasbag, air path or tripping rope, etc., with simple and convenient operation and reliable work, not damaging the gasbag or enwinding the rope, etc., and is extremely suitable for deep well long-distance operation. The probe always keeps expending when moving upwards, the test can be carried out at any positions and the test efficiency is extremely and largely improved. The elastic rod can be lengthened or shortened according to the requirement, ensuring the test is not restricted by the neck enlarging or the hole diameter. The elastic rod has the power provided by the spring. No matter how deep the test depth and how large the pressure of the slurry, the elastic rod can smoothly flick, ensuring the expending of the probe and implementing the test.
Description
Technical field
The utility model relates to down-hole elastic wave test probe, the particularly underground low-frequency elastic wave test probe adherent device in boring of measuring geotechnical structure.
Background technology
Present constructional aspect and mechanical characteristic in order to measure ground is just must can make probe adherent after on the probe air bag being installed.Though gas cell can make probe adherent, air bag breakage rate in the reality test is higher.And each test position all needs once to inflate-exhaust cycle in well.Time in the actual test more than 85% all has been used in the inflation exhaust process repeatedly.Inflation usually adopts the inflator manpower to carry out, and not only labour intensity is big, and operates complicatedly, and efficient is extremely low.Owing to be full of water or mud in the well, after MTD was greater than 10 meters, inflation was just quite difficult.After 40 meters, can not carry out the manual inflation.For expanding the location of neck degree in the well, then can't test greater than air bag expansion limit.Airbag aeration needs special-purpose gas piping, has increased the cable cost.
The purpose of this utility model is the above-mentioned difficulties that will overcome prior art, for down-hole elastic wave test probe provides a kind of novel adherent device.
Solution of the present utility model is: at the common elastic rod of a carrying magnetic material of upper articulation of sonde body; Be provided with compression spring between elastic rod and the sonde body; On sonde body, be provided with the electromagnet of absorption elastic rod.
The articulated position of above-mentioned elastic rod can be located on the cross bar, and the length of cross bar makes the elastic rod energy smooth in the side of sonde body.
The head of above-mentioned elastic rod can be made circular-arc.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the adherent device of underground test probe.
Referring to accompanying drawing, on the cross bar 6 at probe top, be provided with hinge 4.Elastic rod 2 is hinged by hinge 4 and sonde body 1.Between elastic rod 2 and sonde body 1, be provided with compression spring 3.Compression spring can outwards be pushed elastic rod open automatically.Have electromagnet 5 on the sonde body 1.The relevant position has Magnetized Material sheet 7 (as iron and steel sheet etc.) on the elastic rod 2, can be attracted by electromagnet 5.The also available Magnetized Material of elastic rod 2 itself is made.The articulated position of elastic rod 2 is located on the cross bar 6 among the figure, and the length of cross bar makes elastic rod 2 energy smooth in the side of sonde body 1.
Before probe is gone into the well, apply less voltage (6v) or electric current, the elastic rod 2 that the electromagnet 5 on the probe just can be hinged with an end tightly is adsorbed on the sonde body 1.Because elastic rod is flattened on the probe side, the two is very compact in conjunction with getting, and probe can be up and down in well freely, as shown in Figure 2.Elastic rod head 8 is done camber to reduce resistance.
During work, earlier probe is transferred to test position the darkest in the well, then electromagnet is cut off the power supply to discharge elastic rod 2, strong compression spring 3 will flick the bottom of elastic rod 2 from sonde body 1, as shown in Figure 1.Open elastic rod 2 props up a side borehole wall can make sonde body 1 be close on the opposite side borehole wall.Because the elastic rod top is hinged on the probe, can freely stretch in the bottom, as long as firmly upwards draw from well head, probe just can move up smoothly, and in moving process, probe touch the borehole wall all the time.So just do not need all adherent work of specialize of each test position has obviously been improved testing efficiency.
The utility model compared with prior art has following advantage:
1. discharge elastic rod with electromagnet, saved air bag, gas circuit or dropout rope etc. Easy and simple to handle, reliable operation, Air bag breakage or tricing line winding etc. can not take place, and are particularly suitable for the deep-well remote-controlled operation.
2. move past in the journey on the probe, remain adherent, at any time can both test at an arbitrary position, avoided using air bag Repeatedly fill, the trouble of exhaust, greatly improved testing efficiency.
3. elastic rod can lengthen or shorten as required, makes test no longer be expanded the restriction in neck or aperture.
4. have the power that spring provides owing to elastic rod self, so no matter how dark MTD is, mud pressure is much, Elastic rod can both flick smoothly, guarantees that probe is adherent, realizes test.
5. use in the supporting cable of elastic rod, no longer need gas piping, reduced the cable cost.
