Description

Technical Field

[0001] This utility model relates to the field of earthquake monitoring technology, and in particular to a lightweight soundproof earthquake monitoring instrument housing. Background Technology

[0002] my country is a country where earthquakes occur relatively frequently, especially the Qinghai-Tibet Plateau, which is a geologically active area. Real-time monitoring using earthquake monitoring instruments can provide scientists with scientific monitoring data, help them understand the patterns of internal Earth movement and change in the earthquake zone, and reduce the loss of life and property caused by earthquakes.

[0003] An earthquake monitoring instrument can sense the vibration signals generated by seismic waves propagating inside the Earth, and is used to analyze the occurrence and propagation of earthquakes. It consists of sensors, signal amplifiers, and recorders. The core component is the sensor, which senses the vibration signals of seismic waves and converts them into electrical signals for amplification, transmission, recording, and analysis.

[0004] Earthquake monitoring instruments are buried deep underground, and other sound waves on the surface can affect the collection of seismic vibration signals. The sensors need to isolate these sound waves, and the instruments buried deep underground need to be protected against moisture and bacteria. All of these require protection by the monitoring instrument casing. At the same time, when working in the field on the Qinghai-Tibet Plateau, the instruments and equipment carried by personnel need to be as lightweight as possible to reduce the labor intensity of research personnel.

[0005] The earthquake monitoring instruments currently in use use thick and dense steel materials for their protective shells to achieve sound insulation. However, steel materials are prone to corrosion when exposed to moisture, and the solid shells are too heavy, making them difficult to carry at high altitudes. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lightweight, sound-insulating earthquake monitoring instrument housing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A lightweight soundproof earthquake monitoring instrument housing includes a cylinder body, a front cover, and a bottom cover. The cylinder body includes a cylinder body panel and a cylinder body sandwich layer. The cylinder body panel has a double-layer structure, and the cylinder body sandwich layer is filled in the cylinder body panel. The front cover and the bottom cover are detachably installed at the upper and lower ends of the cylinder body through a connecting structure, respectively.

[0009] Preferably, the connecting structure includes a plurality of screw-hole arc plates, which are embedded in the recessed assembly areas at both ends of the cylinder body. Both the top cover and the bottom cover are provided with assembly holes, and screws are provided in the assembly holes. The screws are threadedly connected to the screw-hole arc plates.

[0010] Preferably, the cover includes a cover panel and a cover core layer, the cover core layer is filled in the cover panel, and the cover has a circular boss structure.

[0011] Preferably, the bottom cover includes a bottom cover panel and a bottom cover core layer, the bottom cover core layer is filled in the bottom cover panel, and the bottom cover has a circular boss structure.

[0012] Preferably, two through-hole arc-shaped plates are pre-embedded symmetrically along the axis at the upper end of the cylinder core layer, and the cylinder panel is provided with corresponding through holes.

[0013] Preferably, the bottom cover sandwich layer has pre-embedded square plates with equally spaced annularly distributed screw holes, and a square plate with a through hole pre-embedded in the center.

[0014] Preferably, the inner rings at both ends of the cylinder body are provided with recessed areas corresponding to the bosses of the top cover and bottom cover, and the sides of the bosses of the top cover and bottom cover are provided with triangular annular grooves and rectangular annular grooves, and triangular sealing rings and rectangular sealing rings are respectively fitted into the grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Basalt-reinforced epoxy resin composite panels have high corrosion resistance and chemical stability, high temperature and low temperature stability, and can work stably for a long time in high humidity, acid, alkali and salt media. They are moisture-proof and easy to clean, and have broad application prospects in harsh outdoor environments such as the Qinghai-Tibet Plateau.

[0017] (2) Lightweight: The density of basalt composite material is only about one-quarter that of steel, and the density of aluminum foam sandwich layer is only about one-tenth that of aluminum. The overall weight reduction of the seismic monitoring instrument shell is ≥90%, and the lightweight effect is very significant, with obvious advantages in field operations.

[0018] (3) The composite material panel has high strength and the sandwich structure has good rigidity, ensuring the safety of the core components inside the shell;

[0019] (4) The two sealing rings can effectively insulate against sound and moisture, and the shell is easy to disassemble and assemble;

[0020] (5) The sound insulation effect is good. Through the thickness design of the panel and sandwich panel, under the condition that the shell size is the same, the decibel reduction is comparable to that of high-density steel. Attached Figure Description

The surfaces of the cylindrical body panel 11 and the core layer 12 are bonded together to form a high-rigidity sandwich panel structure.

[0034] At each end of the cylinder body 1, there is a recessed assembly area with a solid structure. Each area has three evenly distributed screw-hole arc-shaped plates 13 embedded inside for fastening with the face cover 2 and the bottom cover 3. Two through-hole arc-shaped plates 14 are embedded symmetrically along the axis at the upper end of the sandwich layer, through which data cables pass for data transmission.

[0035] Furthermore, the cover 2 has a circular boss structure, the circular flange is a composite material solid structure, and the boss is a sandwich panel structure.
