Description

Technical Field

[0001] The utility model relates to the technical field of seismic geophones, in particular to a novel ultra-low frequency seismic geophone. Background Art

[0002] A geophone is a device that detects some useful information in a wave signal. It is a device used to identify the existence or change of waves, oscillations or signals. A geophone is usually used to extract the information it carries. China Public Invention: Announcement No.: CN205229471U discloses a new type of ultra-low frequency seismic geophone. The invention can reduce the frequency of the seismic geophone while reducing its own external volume. A single-rib helical spring sheet is added below the coil lower spring sheet to increase the supporting force; the output sensitivity of the seismic geophone in the low frequency band is improved, and the deep low-frequency effective information of seismic exploration is effectively picked up, which meets the needs of high-resolution exploration, improves the fidelity of seismic wave data acquisition, and further reduces the cost of seismic exploration. However, there are certain problems. When the existing geophone is leveled, it is necessary to insert the tail cone into the ground first, and then level the geophone. However, during leveling, the shaking of the tail cone caused by the geophone body affects the coupling effect between the tail cone and the ground.

[0003] For this purpose, application number: 201920895780.9 discloses a novel ultra-low frequency seismic geophone, including a geophone body, the bottom of which is symmetrically fixedly connected with two first fixing seats, the bottom of which is hinged with a connecting rod, one end of which is hinged with a second fixing seat away from the bottom of the first fixing seat, a base is provided below the geophone body, and two grooves are symmetrically provided on both sides of the upper surface of the base; when installing the geophone, the base is made close to the ground by inserting the tail cone into the ground, and then the two rod bodies are pushed, the rod body pushes the bearing, the bearing pushes the second fixing seat, the second fixing seat pushes the connecting rod, and the connecting rod pushes the first fixing seat, so that the geophone body is leveled, and after leveling, the rod body is rotated so that the first limiting rod is inserted into the limiting groove to limit the position of the first limiting rod, and during the leveling process, the tail cone will not be driven to shake, which is convenient for leveling the geophone and does not affect the fixing effect of the geophone;

[0004] In the above-mentioned patent with application number 201920895780.9, only the detector is leveled after the tail vertebrae are inserted, which does not affect the fixation of the detector. However, there are still some shortcomings during use: 1. The reason for the tilt of the detector and the tail vertebrae is due to the tilted insertion during insertion. It cannot fundamentally solve the problem of the detector being level relative to the ground, and the subsequent separate leveling method increases the workload; 2. After the tail vertebrae are pulled out from the ground after use, there is a lack of structure for cleaning and shielding and protecting it. After the tail vertebrae are pulled out, a lot of mud will be attached to it, which requires personnel to clean it separately, and the tail vertebrae are exposed to the outside when carried, and there is a risk of accidental contact and breakage; it cannot meet the use requirements. Based on the above situation, we redesigned it and proposed a new ultra-low frequency seismic detector. Utility Model Content

The tail vertebra 101 can be shielded and protected when carried, and the soil on the outside of the tail vertebra 101 can be automatically wiped and cleaned during the upward movement of the tail vertebra 101, without the need for personnel to clean it separately, thereby improving work efficiency.

[0028] Working principle: When in use, when the ultra-low frequency seismic detector body 100 is not fixed on the ground, the telescopic shielding sleeve 5 fully shields and protects the coccyx 101, and cooperates with the two L-shaped guide rods 3 to shield both sides of the coccyx 101, which can effectively reduce the risk of the coccyx 101 being accidentally hit and broken;

[0029] When fixing the ultra-low frequency geophone body 100 on the ground, it is necessary to insert the tail vertebra 101 into the ground. When inserting, first make the anti-skid rubber at the bottom of the horizontal plate 2 contact with the ground. When in contact with the ground, the horizontal plate 2 is horizontal relative to the ground, and then the components above the horizontal plate 2 are horizontal relative to the ground. After the horizontal plate 2 contacts the ground, the horizontal plate 2 is fixed to the ground by two T-shaped anchor rods 9 and the fixing block 8. After fixing, the T-shaped compression bolt 6 is rotated in the opposite direction to separate it from the L-shaped guide rod 3 on the right, thereby releasing the fixation of the right guide block 1. Then, the ultra-low frequency geophone body 100 can be pressed downward. The ultra-low frequency geophone body 100 drives the two guide blocks 1 to slide downward on the corresponding L-shaped guide rods 3 respectively. While the guide block 1 moves downward, the corresponding spring 4 is compressed. When the two guide blocks 1 compress the telescopic shielding sleeve 5, the ultra-low frequency geophone body 100 drives the tail vertebra 101 downward through the annular tube 14 and is inserted into the ground. In the process of the ultra-low frequency geophone body 100 driving the tail vertebra 101 to move downward, the ultra-low frequency geophone body 100 is vertically guided by the cooperation of the guide block 1 and the L-shaped guide rod 3, which can effectively reduce the tilting of the ultra-low frequency geophone body 100 during the downward movement, and can ensure that the ultra-low frequency geophone body 100 moves vertically downward, so that the inserted tail vertebra 101 can be ensured to move vertically downward, and then the ultra-low frequency geophone body 100 fixed by the tail vertebra 101 will not tilt, and can remain horizontal relative to the ground, thereby fundamentally solving the tilting of the ultra-low frequency geophone body 100, and no separate leveling operation is required, thereby reducing labor intensity;

[0030] When the ultra-low frequency geophone body 100 moves downward to contact with the touch switch 12, it proves that the ultra-low frequency geophone body 100 moves to the set position at this time, then the touch switch 12 is triggered to turn on and transmit the signal to the controller 10, and the controller 10 controls the sound and light alarm 11 to send out a sound and light alarm to remind the personnel. After receiving the reminder, the personnel can stop pressing the ultra-low frequency geophone body 100 and rotate the T-shaped compression bolt 6 forward. The T-shaped compression bolt 6 rotates and moves to the left to be in close contact with the L-shaped guide rod 3 on the right side. Under the friction between the T-shaped compression bolt 6 and the L-shaped guide rod 3, the guide block 1 is fixed, thereby fixing the ultra-low frequency geophone body 100;

[0031] When the coccyx 101 is subsequently pulled out from the ground, the T-shaped compression bolt 6 can be rotated in the opposite direction again to separate it from the L-shaped guide rod 3, and the ultra-low frequency seismic detector body 100 can be pulled upward, and the ultra-low frequency seismic detector body 100 drives the coccyx 101 to move upward from the ground. The ultra-low frequency seismic detector body 100 also drives the two guide blocks 1 to relax the compression force on the spring 4 and the telescopic shielding sleeve 5 upward, so that the spring 4 and the telescopic shielding sleeve 5 are gradually reset. While the coccyx 101 moves upward, its outer side rubs against multiple bristles 15. Under the friction force, the soil attached to the outer side of the coccyx 101 can be rubbed off, thereby achieving the purpose of automatically cleaning the soil on the outer side of the coccyx 101 during the upward movement of the coccyx 101. There is no need for personnel to clean it separately, which reduces labor intensity. When the coccyx 101 is completely moved out of the ground, the coccyx 101 is shielded and protected again by the telescopic shielding sleeve 5, and then the T-shaped anchor rod 9 can be pulled out from the ground to release the fixation of the entire device.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
