Description

Technical Field

[0001] This utility model relates to the technical field of geological exploration, specifically a three-component high-sensitivity detector. Background Technology

[0002] Three-component geophones are special geophones used in multi-wave exploration. Unlike conventional single-component seismic geophones, each geophone contains three mutually perpendicular sensors to record the three components of the particle vibration velocity vector, which are used to simultaneously record P-waves, S-waves, and converted waves. However, existing three-component geophones are not easy to assemble, and the internal sensing core is prone to displacement during daily transport and transportation of geophones, resulting in reduced detection accuracy.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example: Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a three-component high-sensitivity detector, including a main housing 1. A tail cone 2, inserted into the ground, is located at the bottom of the main housing 1. A high-sensitivity vertical detector core 3 is installed in the lower part of the inner cavity of the main housing 1. Inside the main housing 1, and above the high-sensitivity vertical detector core 3, a set of high-sensitivity X-axis horizontal detector cores 5 and 6, which are not on the same plane and perpendicularly intersecting each other, are installed via a positioning frame 4. A six-core transmission cable 7 is provided on the main housing 1, connected to the positive and negative terminals of the high-sensitivity vertical detector core 3, the high-sensitivity X-axis horizontal detector core, and the high-sensitivity Y-axis horizontal detector core, respectively. The output end of the six-core transmission cable 7 is converted into three outputs via a one-to-three circuit board. Two-core cables 8 are connected to three component connectors 9 for X, Y, and Z respectively. A specific main housing 1 is set up, and the high-sensitivity vertical detector core 3, the high-sensitivity Y-axis horizontal detector core 6, and the high-sensitivity X-axis horizontal detector core 5 are installed sequentially from bottom to top inside the main housing 1. The positioning frame 4 and the fixing frame are used to position the high-sensitivity X-axis horizontal detector core 5 and the high-sensitivity Y-axis horizontal detector core 6. The positioning frame 4 has a downward pressing effect on the high-sensitivity vertical detector core 3, and the top cover 10 also has a downward pressing effect on the high-sensitivity X-axis horizontal detector core 5. This facilitates assembly and has a good positioning effect, effectively avoiding displacement during daily transportation and handling, which would lead to a decrease in accuracy.

[0021] A top cover 10 is installed on the top of the main housing 1. A sealing ring 11 is provided on the top cover 10 to seal the connection between the top cover 10 and the main housing 1. A pressure cover 12 is installed on the top cover 10, and a level 13 is installed on the top of the pressure cover 12. The top cover is fixed to the top of the main housing with bolts and sealed by the sealing ring, thus having a good waterproof and dustproof effect. The level 13 plays a role in level detection during installation, so that the detector is installed horizontally on the ground, avoiding large detection errors caused by tilting.

[0022] A sealing sleeve 14 is installed between the top cover 10 and the pressure cover 12, and a circuit board 15 is fixed on the top of the top cover. The positive and negative terminals of the high-sensitivity vertical detector core 3, the high-sensitivity X-axis horizontal detector core 5, and the high-sensitivity Y-axis horizontal detector core 6 are connected to the input terminal of the circuit board 15 via signal lines, and the output terminal of the circuit board 15 is connected to a six-core transmission cable 7, which facilitates wiring. The top cover is provided with multiple wire holes.

[0023] The bottom of the main housing 1 is provided with a positioning groove 16 for positioning the high-sensitivity vertical detector core 3, and the top of the positioning frame 4 is provided with a limiting groove 17 for limiting the top of the high-sensitivity vertical detector core 3. This plays a positioning role and prevents the high-sensitivity vertical detector core 3 from tilting or shifting.

[0024] The high-sensitivity X-axis horizontal detector core 5 is mounted on the top of the positioning frame 4 via a fixing frame 18. The fixing frame 18 is provided with a fixing groove 19 for positioning the high-sensitivity X-axis horizontal detector core 5, which serves the positioning function and prevents the high-sensitivity X-axis horizontal detector core 5 from tilting or shifting.

[0025] The top cover 10 presses down on the high-sensitivity X-axis horizontal detector core 5. The top cover 10 has a groove 20 that matches the top of the high-sensitivity X-axis horizontal detector core 5, which serves to position the core and prevent it from tilting or shifting.

[0026] The outer wall of the positioning frame 4 is closely fitted with the inner wall of the main housing 1, which provides a good positioning effect for the high-sensitivity Y-axis horizontal detector core 6.

[0027] Working Principle: This invention features a specific main housing 1, inside which a high-sensitivity vertical detector core 3, a high-sensitivity Y-axis horizontal detector core 6, and a high-sensitivity X-axis horizontal detector core 5 are sequentially installed from bottom to top. A positioning frame 4 and a retaining frame are used to position the high-sensitivity X-axis horizontal detector core 5 and the high-sensitivity Y-axis horizontal detector core 6. The positioning frame 4 exerts downward pressure on the high-sensitivity vertical detector core 3, while the top cover 10 also exerts downward pressure on the high-sensitivity X-axis horizontal detector core 5. This facilitates assembly and provides excellent positioning, effectively preventing displacement during daily transport and handling, which could lead to reduced accuracy.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
