Description

Technical Field

[0001] The present application relates to the technical field of ground wave microseismic detection, and more specifically, to a ground wave microseismic detector. Background Art

[0002] A seismic wave detector is a device used to detect seismic waves. It can help scientists understand the internal structure of the earth and the mechanism of earthquakes. Its working principle is to use the physical characteristics of seismic waves during propagation for measurement. Seismic wave detectors can determine underground structures and the location of earthquakes by measuring the speed and direction of these waves. Among them, the SmartSolo node-type mineral exploration seismic instrument inserts the ground pulse probe into the soil, uses seismic exploration technology to collect data and image, and uses artificial seismic waves to study the properties of underground rocks and search for energy such as oil, natural gas, and minerals.

[0003] However, this node-type seismograph was found to have some drawbacks after use. The ground pulse probe of this seismograph can only detect seismic waves in a single channel, and cannot detect seismic waves in multiple directions at the same time. Moreover, when inserted into the ground, the single-foot insertion method will cause the main unit and the ground pulse probe to move upward and cause tipping when detecting seismic waves, thus affecting normal use.

[0004] In view of this, we propose a ground wave microseismic detector. Utility Model Content

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] A ground wave microseismic detector includes a main unit 1 and a main ground pulsation probe 2. The main ground pulsation probe 2 is provided with a plurality of auxiliary ground pulsation probes 3 distributed in a ring. The plurality of auxiliary ground pulsation probes 3 can be expanded or contracted synchronously. The auxiliary ground pulsation probes 3 are connected to the main ground pulsation probe 2. The main unit 1 is detachably provided with a protective cover 5. The main ground pulsation probe 2 and the auxiliary ground pulsation probes 3 are sleeved in the protective cover 5.

[0032] Reference Figure 1-Figure 9The main unit 1 and the ground pulse probe are existing equipment, and the model is IGU-16HR. The main ground pulse probe 2 is fixed at the bottom geometric center of the main unit 1. When in use, the multiple auxiliary ground pulse probes 3 are pulled outward, and the spacing between the multiple auxiliary ground pulse probes 3 becomes larger to increase the detection range. The multiple auxiliary ground pulse probes 3 and the main ground pulse probe 2 are inserted into the soil. Under the joint action of the multiple auxiliary ground pulse probes 3 and the main ground pulse probe 2, the overall stability of the main unit 1 is improved, and a multi-channel detection method is used for multi-directional seismic wave detection, and multi-directional support improves the support stability of the main unit 1; after the multiple auxiliary ground pulse probes 3 are brought closer to the main ground pulse 2, the protective cover 5 is threadedly connected to the main unit 1 to prevent the main ground pulse probe 2 and the auxiliary ground pulse probe 3 from injuring the user when carrying.

[0033] The main ground pulse probe 2 is sleeved with a collar 4 , and both the main ground pulse probe 2 and the auxiliary ground pulse probe 3 are fixed with ear plates 402 , and a connecting plate 401 is rotatably connected between the two ear plates 402 .

[0034] Reference Figure 2 and Figure 6 and Figure 7 The two ends of the connecting plate 401 are axially connected to the two ear plates 402. When the auxiliary ground pulse probe 3 on one side is stretched outward, the ring 4 slides upward along the main ground pulse probe 2 under the transmission of the connecting plate 401, and the remaining auxiliary ground pulse probes 3 are supported outward by the connecting plate 401, so that multiple auxiliary ground pulse probes 3 expand outward synchronously, and when the auxiliary ground pulse probe 3 on one side is pressed toward the direction of the main ground pulse probe 2, the ring 4 slides downward at this time, and pulls the remaining auxiliary ground pulse probes 3 to shrink close to the main ground pulse probe 2 through the connecting plate 401.

[0035] A plurality of transmission rods 201 are annularly fixed on the upper end of the main ground pulse probe 2 , and a mounting hole 301 adapted to the transmission rod 201 is opened in the auxiliary ground pulse probe 3 .

[0036] Reference Figure 2 and Figure 4 and Figure 5 The transmission rod 201 passes through the mounting hole 301, and the auxiliary ground pulse probe 3 slides horizontally along the transmission rod 201 for adjustment. The auxiliary ground pulse probe 3 transmits the vibration to the main ground pulse probe 2 through the transmission rod 201 to ensure the vibration transmission effect. At the same time, the limit blocks 202 are fixed at the separated ends of the transmission rod 201 to prevent the auxiliary ground pulse probe 3 from falling off the transmission rod 201.

[0037] An annular thread groove 101 is formed at one end of the main machine 1 close to the main ground pulse probe 2 , and the annular thread groove 101 is threadedly connected to the open end of the protective sleeve 5 .

[0038] Reference Figure 2 and Fig. 9The open end of the protective sleeve 5 is threadedly connected to the annular thread groove 101 to facilitate quick disassembly and assembly of the protective sleeve 5 and the host 1.

[0039] A limiting ring 501 is coaxially fixed inside the protective sleeve 5 .

[0040] Reference Figure 8 and Fig. 9 When the protective sleeve 5 is threadedly connected to the main unit 1, the multiple auxiliary ground pulse probes 3 are sleeved in the limiting ring 501 and abut against the inner wall of the limiting ring 501. At this time, under the limiting effect of the limiting ring 501, the auxiliary ground pulse probes 3 are prevented from shaking in the protective sleeve 5.

[0041] The collar 4, the connecting plate 401, the ear plate 402, the main ground pulse probe 2, the auxiliary ground pulse probe 3 and the transmission rod 201 are made of the same material.

[0042] The collar 4, connecting plate 401, ear plate 402, main ground pulse probe 2, auxiliary ground pulse probe 3 and transmission rod 201 are made of the same material to ensure the same vibration frequency when vibrating, avoiding the problem of vibration frequency difference caused by different materials.

[0043] The auxiliary ground pulse probe 3 is a right-angled triangular plate structure.

[0044] Reference Figure 4 , through the auxiliary earth pulse probe 3 of the right-angled triangular plate structure, and the lower end is a pointed tip, so that the auxiliary earth pulse probe 3 can be inserted into the soil.

[0045] The upper end of the auxiliary ground pulse probe 3 abuts against the lower end of the main unit 1 .

[0046] Reference Figure 2 When the auxiliary earth pulse probe 3 expands outward and presses the main unit 1 upward, the auxiliary earth pulse probe 3 rests against the lower surface of the main unit 1 to prevent the transmission rod 201 from bending when the auxiliary earth pulse probe 3 is pressed into the soil.

[0047] Working principle: When in use, remove the protective cover 5 from the lower end of the main unit 1 in a counterclockwise spiral, then pull one of the auxiliary ground pulse probes 3, the collar 4 slides upward along the main ground pulse probe 2, and the remaining auxiliary ground pulse probes 3 are supported outward by the connecting plate 401, so that multiple auxiliary ground pulse probes 3 expand outward synchronously, and then press the main unit 1 to insert the auxiliary ground pulse probes 3 and the main ground pulse probe 2 into the soil;

[0048] After use, pull out the main unit 1, the main ground pulse probe 2 and the auxiliary ground pulse probe 3 from the soil, then press the multiple auxiliary ground pulse probes 3 relative to each other, slide the ring 4 downward, and pull the remaining auxiliary ground pulse probes 3 toward the main ground pulse probe 2 through the connecting plate 401 to shrink, and finally thread the protective cover 5 onto the main unit 1, and the outer wall of the auxiliary ground pulse probe 3 rests against the inner wall of the limiting ring 501, so that the storage is completed to prevent the user from being stabbed when carrying.
