The working principle and the using process of the invention are as follows: when the wavelet analysis device based on elastic wave exploration is carried, a detector is firstly accommodated, a sponge block 2807 is squeezed by the detector, two connecting wires of the detector are respectively placed at two second wire grooves 2810, after all the sponge blocks 2807 are inserted into the geophone, the second half-rod 2811 is passed through the shaft seat 2805, so that the second half-rod 2811 covers the top end of the first half-rod 2806, then, the first semicircular bar 2806 and the second semicircular bar 2811 are rotated so that the geophone connection wire is wound around the outside of the first semicircular bar 2806 and the second semicircular bar 2811, the geophone connection terminal is placed on the side of the position limiting plate 2809, the connection wire is placed in the first wire groove 2808, the tight connection wire pulls the geophone connection terminal, and the geophone connection terminal is supported by the position limiting plate 2809, then, the handle groove 2804 is pushed to return the swing plate 2801 to the housing chamber 3, and the seal rubber pad 2803 abuts against the partition plate 4 to ensure the stability of the swing plate 2801;
after the receiver is completely stored, the cover plate 1801 is turned over, the cover plate 1801 is placed vertically by swinging the connecting lug plate 1802 by taking the fixed shaft 17 as an axis, at the moment, the sealing rubber 1803 is plugged into the rubber strip 19, then the mounting shaft 24 inside the sleeve 23 is rotated to make the snap-gauge 25 block the cover plate 1801, so as to ensure the stability of the cover plate 1801 in the carrying process, then the retaining ring 1806 is pulled, the retaining ring 1806 passes through the limiting hole 20, and the adjusting notch 22 of the supporting rod 21 is buckled, according to the body condition of the user, the proper adjusting notch 22 is selected to ensure that the elastic band 1805 has proper tightness, when the user carries the device, the shoulder and the hand pass through the elastic band 1805, the sliding block 1807 is slid, so that the auxiliary bandage 1808 is positioned in front of the chest, the user can stably carry the device, the back of the user is in contact with the protective sponge 1804, and discomfort caused by direct contact of the back of the user with the covering plate 1801 is reduced;
when the box body 1 is used, the mounting shaft 24 is rotated, so that the clamping plate 25 does not clamp the covering plate 1801 tightly, the retaining ring 1806 is loosened, the covering plate 1801 is drawn back from the limiting hole channel 20, the covering plate 1801 is swung by taking the fixing shaft 17 as an axis again, the covering plate 1801 is placed at the top end of the shielding plate 12, the limiting hole channel 20 is in contact with the ground through the supporting rod 21, and the stability of the box body 1 is guaranteed;
then, the geophone is taken out, when the geophone is taken out, firstly, the handle groove 2804 is pulled and pulled, the swing plate 2801 is opened and is kept stable under the action of the limiting rope 2802, then, the connecting end of the geophone is pulled, the first semicircular rod 2806 and the second semicircular rod 2811 are rotated, a wound wire is loosened, when the wire is not wound on the first semicircular rod 2806 and the second semicircular rod 2811, the second semicircular rod 2811 is pulled out from the end of the shaft seat 2805, namely, the geophone can be taken out, the geophone is connected with each other through the connecting end and is installed at a specified position, then, the storage battery 7 is connected, after the vibration exciter is used, the geophone transmits signals to the PLC controller 5, the PLC controller 5 extracts daughter waves to be compared with data in the data memory 6, information is output to the touch display screen 2 according to the degree of correlation, and the wavelet analysis of elastic wave exploration is completed;
when the detection is carried out in a high-temperature area, the heat radiation fan 9 needs to be started in the detection process, the heat radiation fan 9 generates upward airflow through the heat radiation fan 9, high-temperature gas in the box body 1 is output through the heat radiation notch 10, the airflow flows to two sides under the action of the inclined plate 8 and the drainage block 13, the first magnetic strip 14 is separated from the second magnetic strip 16 when the gas flows, the shielding cloth 15 inclines, the airflow stably flows, after the heat radiation fan 9 is closed, the first magnetic strip 14 and the second magnetic strip 16 are mutually attracted under the condition of no gas flow, the dust is prevented from entering the box body 1 through the heat radiation notch 10 under the action of the shielding plate 12 and the shielding cloth 15, when the heat radiation fan 9 generates airflow, the airflow flows into the accommodating chamber 3 from the handle groove 2804, passes through the anti-leakage gauze 31, the drying box 30 and the ventilation holes 26 of the partition plate 4 to enter the vicinity of each electric appliance component, and is finally discharged from the heat radiation notch 10 to the shielding, in the whole gas flowing process, the drying agent in the drying box 30 can effectively absorb water vapor, the damage to an electric appliance caused by the water vapor is reduced, meanwhile, the drying box 30 is connected with the drying box 30 through the T-shaped mounting block 29 in a sliding mounting mode, the drying box 30 can be taken out by pulling the handle 32, and the failed drying agent is replaced to keep the continuous drying effect.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
