Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wave velocity detection equipment, and more specifically, to a wave velocity detection equipment for seismic exploration. Background Art
[0002] Earthquakes, also known as ground motions and seismic movements, are vibrations caused by the rapid release of energy from the earth's crust, during which seismic waves are produced. Seismic exploration is a geophysical exploration method that uses the differences in elasticity and density of underground media to infer the properties and morphology of underground rock formations by observing and analyzing the propagation patterns of seismic waves generated by artificial earthquakes underground.
[0003] During the detection process, the probe needs to be lowered into a pre-dug measuring hole, and several depth marks are made on the cable in advance with a spacing of 1m. Then the probe is lowered to the bottom of the borehole, and the cable is pulled to slowly lift the probe. It is lifted 1m for detection once, but the depth mark is easy to fall off after long-term use. It is difficult to ensure that the lifting height is 1m each time by judging the lifting distance based on the depth mark, and the more times it is lifted, the greater the cumulative error. In addition, during the probe detection process, due to the radial vibration of the drill bit when the drilling equipment is drilling, even if a drill bit with the same diameter as the measuring hole is selected for drilling, the diameter of the measuring hole will be slightly larger than the diameter of the probe, resulting in the probe extending into the measuring hole and not being able to fit well with the measuring hole, affecting the detection accuracy.

[0027] Since the outer surfaces of the second extrusion wheel 525 and the first extrusion wheel 57 are fixedly connected with a plurality of latch teeth 526, which are latched on the outer surface of the cable 37 through the latch teeth 526, the first extrusion wheel 57 and the second extrusion wheel 525 are prevented from sliding when the cable 37 moves, thereby affecting the detection accuracy of the detection probe 6 inside the measuring hole 2.
[0028] Second embodiment
[0029] As attached Figure 1 , 2 and 5 are an embodiment of the utility model, in which the electromagnet 62 generates magnetic force to magnetically attract the iron ring 65, so that the electromagnet 62 and the iron ring 65 are close to each other, and the unfolding rod 66 is unfolded to make the ball 67 fit on the inner wall of the measuring hole 2, and the fluctuation is transmitted to the probe body 61 through the transmission of the unfolding rod 66, thereby improving the detection accuracy of the probe body 61.

[0031] By providing the support wheel 36, the friction between the placement hole 35 and the cable 37 is reduced, and the wear of the cable 37 is reduced. In addition, a placement groove 34 is opened on the placement plate 33 to facilitate the placement of the wave speed tester 4 on the placement plate 33, which is convenient for operation and reduces the pollution of the wave speed tester 4 on the ground.
[0032] Among them, the detection probe 6 includes a probe body 61, the top of the probe body 61 is connected to the cable 37, the bottom of the probe body 61 is fixedly connected to an electromagnet 62, the bottom of the electromagnet 62 is fixedly connected to a fixing rod 63, the outer surface of the fixing rod 63 is movably connected to an iron ring 65, and the outer surface of the fixing rod 63 is located between the electromagnet 62 and the iron ring 65 and is movably connected to a reset spring 68.

[0035] When in use, the detection probe 6 is placed from the placement hole 35 through the support wheel 36 into the interior of the sliding track 51.

The second extrusion wheel 525 and the first extrusion wheel 57 are respectively clamped on both sides of the cable 37. Then, the rotating motor 54 controls the rotation of the first extrusion wheel 57, so that the second extrusion wheel 525 and the first extrusion wheel 57 rotate, and gradually lower the detection probe 6 at the bottom of the cable 37. When the detection probe 6 enters the interior of the measuring hole 2, the roller meter 59 is started to calculate.
