Description

Technical Field

[0001] This utility model belongs to the field of seismic detector technology, and relates to a detector pad, particularly a three-component detector pad device. Background Technology

[0002] In traditional seismic exploration, obtaining high-resolution images of subsurface structures relies primarily on the accurate reception of P-wave reflections. With the increasing demand for complex geological structures, deep exploration, and multi-wave overlay information, many regions require three-component geophones for multi-wave exploration. However, existing three-component geophones are expensive, resulting in high construction costs. Therefore, effectively modifying the numerous existing single-component P-wave geophones to achieve the performance of three-component geophones has become a pressing issue. Summary of the Invention

[0003] The purpose of this utility model is to provide a three-component detector pad device. The device has a simple structure, is easy to manufacture and install, is convenient for on-site installation, and has low construction and modification costs. It can use three single-component longitudinal wave detectors to achieve multi-wave exploration effects and has extremely high application value.

[0004] The purpose of this utility model is achieved as follows: A three-component detector pad device includes a first pad, a second pad, a third pad, a wing nut, a leveling nut, and a connecting shaft. The second pad is disposed above the first pad, and the third pad is disposed above the second pad. A screw is fixedly disposed on the lower part of the first pad, and a leveling nut is installed on the lower end of the screw. The first pad and the second pad are connected by a connecting shaft, and a wing nut is installed on the top of the connecting shaft. The second pad and the third pad are connected by a hinge. Tapered holes are respectively disposed on the first pad, the second pad, and the third pad, and a single-component detector is installed in the tapered holes.

[0005] A bushing is provided in the tapered hole, and the bushing is fitted with the plug of the single-component detector.

[0006] The top of the coupling is provided with a thread that matches the wing nut.

[0007] A spirit level is provided on the side of the first pad.

[0008] The bushing is a rubber sleeve.

[0009] The beneficial effects of this invention are as follows: First, the invention has a simple structure, is easy to install and carry, and is convenient to use. Second, when in use, the three pads are unfolded to assist in receiving seismic wave signals from three directions, thus enabling the acquisition of three-dimensional vibration information of multiple types of seismic waves, including transverse waves, longitudinal waves, and converted waves. The angle of the received component information is accurate and controllable, improving the accuracy of seismic data acquisition. Third, the conical hole in this invention is fitted with a bushing, ensuring that the single-component geophone is securely and tightly installed, preventing shaking during operation and thus improving the accuracy of data acquisition. Fourth, this invention also includes a leveling nut and a spirit level, which can adjust the levelness of the entire device. Attached Figure Description

[0019] Example 1

[0020] As attached Figure 1-7As shown, a three-component detector pad device includes a first pad 1, a second pad 2, a third pad 3, a wing nut 4, a leveling nut 5, and a connecting shaft 6. The second pad 2 is disposed above the first pad 1, and the third pad 3 is disposed above the second pad 2. A screw 7 is fixedly disposed on the lower part of the first pad 1, and a leveling nut 5 is installed on the lower end of the screw 7. The first pad 1 and the second pad 2 are connected by the connecting shaft 6, and a wing nut 4 is installed on the top of the connecting shaft 6. The second pad 2 and the third pad 3 are connected by a hinge 8. Tapered holes 9 are respectively provided on the first pad 1, the second pad 2, and the third pad 3, and a single-component detector 10 is installed in the tapered holes 9.

[0021] A bushing 11 is provided in the tapered hole 9, and the bushing 11 is fitted with the plug of the single-component detector 10.

[0022] The top of the coupling 6 is provided with a thread that matches the wing nut 4.

[0023] A spirit level 12 is provided on the side of the first pad 1.

[0024] The bushing 11 is a rubber sleeve.

[0025] In use, this invention is as follows: First, place the device in the working area, ensuring the leveling nut contacts the ground. Loosen the wing nut, rotate and unfold the first and second pads, adjust to a suitable angle, and then tighten the wing nut. Next, open the hinged third pad and insert the three single-component geophones into the bushings of the first, second, and third pads respectively, ensuring the plugs of the single-component geophones are inserted into the ground. Finally, adjust the leveling nut at the bottom of the first pad, constantly observing the spirit level to ensure the first pad is horizontal. After installation and adjustment, use the single-component geophones mounted on the three pads to collect three-dimensional vibration information of various types of seismic waves, including transverse waves, longitudinal waves, and converted waves.

[0026] Overall, this utility model has the advantages of being easy to install and carry, having accurate and controllable angles for receiving component information, and being able to collect three-dimensional vibration information of multiple types of seismic waves such as shear waves, longitudinal waves, and converted waves, achieving multi-wave exploration effects and improving the accuracy of seismic data acquisition.
