Description

Technical Field

[0001] This utility model belongs to the field of seismic instrument testing technology, and in particular relates to a testing device for the normal operation of a seismic instrument. Background Technology

[0002] With the increasing development of earthquake monitoring and early warning systems, seismic instruments, as core equipment for acquiring seismic wave data and analyzing seismic activity characteristics, directly affect the reliability of earthquake information and the effectiveness of early warnings due to their operational stability and accuracy. Therefore, it is particularly important to regularly check and calibrate the operational status of seismic instruments before and during their use. Traditional seismic instrument testing methods mainly rely on two approaches: static testing or field testing.

[0003] Static testing typically involves measuring basic parameters of seismic instruments, such as sensitivity, output signal stability, and noise levels, in a laboratory environment. While this method facilitates control of environmental factors, it cannot simulate real seismic vibration environments and is insufficient to fully reflect the instrument's working status and response capabilities during actual earthquakes. Field testing involves installing the instrument at a seismic station in the field and verifying its performance through natural earthquake events. Although this method can obtain real data, the sudden and uncontrollable nature of earthquake events results in long testing cycles, high costs, and hinders the rapid troubleshooting and debugging of instrument malfunctions.

[0004] To address these issues, we provide a detection device for the normal operation of seismic instruments. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The platform includes a base plate, a guide rail plate fixed to the upper part of the base plate, and a support plate mounted on the upper edge of the guide rail plate by a slider. The swing assembly includes a connecting rod fixed to the middle position of the edge of the support plate, a swing arm fixed to the connecting rod by a connecting member, a transmission disk rotatably engaged with the end of the swing arm by a shaft, and a motor for driving the rotation of the transmission disk.

[0023] Example

[0024] Please see Figure 1-3 This utility model is a detection device for the normal operation of a seismic instrument, including a frame 100 and a swing assembly 200 mounted on the frame 100. The frame 100 includes a base plate 101, a guide rail plate 102 fixed to the upper part of the base plate 101, and a support plate 104 assembled to the upper edge of the guide rail plate 102 by a slider 103. The swing assembly 200 includes a connecting rod 201 fixed to the middle position of the edge of the support plate 104, a swing arm 203 fixed to the connecting rod 201 by a connecting member 202, a transmission disk 204 rotatably engaged with the end of the swing arm 203 by a shaft, and a motor 208 for rotating the transmission disk 204.

[0025] Specifically, a control display console 300 is installed at the corner of the base plate 101, and the control display console 300 is connected to the motor 208 and the seismic detection instrument; at another corner on the upper side of the base plate 101, a support plate 206 is fixed by a support column 207, the motor 208 is fixed to the end of the support plate 206, the output shaft of the motor 208 is fixed to the middle position of the inner side of the transmission disk 204, and the swing arm 203 cooperates with the outer edge of the transmission disk 204; a limit frame 205 is fixed to the edge of the support plate 206, and the straight groove inside the limit frame 205 cooperates with the connecting piece 202 through a connecting shaft.

[0026] Furthermore, the pair of guide rail plates 102 are arranged in parallel, and the guide rail plates 102 are perpendicular to the base plate 101. A reinforcing strip is welded between the bottom of the guide rail plate 102 and the base plate 101. The edge of the bearing plate 104 has an installation groove for fastener installation, and the seismic detection instrument is fixed to the upper part of the bearing plate 104 by fasteners.

[0027] The device provided in this embodiment for detecting the normal operation of a seismic instrument is easy to operate and can simulate the vibration environment during an earthquake, thereby testing and calibrating the response performance of the seismic instrument. The device consists of two main parts: a frame 100 and a swing assembly 200. The frame 100 serves as the basic support structure of the entire device and is composed of a base plate 101, a guide rail plate 102 fixed to the upper part of the base plate 101, a slider 103, and a support plate 104. The base plate 101 provides a stable base for the entire device. A control display console 300 is provided at its corner for equipment control and data monitoring. A support plate 206 is fixed to its upper part by a support column 207 for mounting drive components. The guide rail plate 102 is arranged parallel to and perpendicular to the base plate 101. The bottom is reinforced with welded reinforcing strips to enhance structural stability. The slider 103 is embedded in the upper edge of the guide rail plate 102, allowing the support plate 104 to slide smoothly on the guide rail to simulate a shear wave vibration scenario. The support plate 104 has a mounting groove on its side, which can be used to firmly fix the seismic instrument under test to its upper surface with fasteners.

[0028] The swing assembly 200 is the core component for vibration simulation, mainly comprising a connecting rod 201, a swing arm 203, a transmission disc 204, a connecting piece 202, a shaft, a limiting frame 205, and a motor 208. The connecting rod 201 is fixed to the middle of the edge of the support plate 104 and connected to the swing arm 203 via the connecting piece 202. The end of the swing arm 203 is rotatably engaged with the transmission disc 204 via a shaft. The motor 208 is fixed to the end of the support plate 206, with its output shaft fixed to the center of the transmission disc 204, driving its rotation. When the motor 208 operates, the transmission disc 204 rotates, driving the connecting rod 201 to reciprocate through the swing arm 203, thereby causing the support plate 104 to move linearly along the guide rail 102, creating a vibration effect simulating an earthquake. The limiting frame 205 is fixed to the edge of the support plate 206 and has an internal straight groove structure. It engages with the connecting piece 202 via a connecting shaft, serving as a guide and limiting element to ensure stable and controllable swinging.

[0029] In practical use, the seismic instrument to be tested is first mounted on the support plate 104 using fasteners and connected to the control display console 300. Then, the motor 208 is started, driving the transmission disc 204 to rotate. Through the linkage mechanism of the swing arm 203 and the connecting rod 201, the support plate 104 produces periodic linear oscillations, simulating the motion of seismic waves. During this process, the seismic instrument outputs signals based on the vibration. The control display console 300 can collect and display relevant data in real time to determine whether the instrument is working properly and whether its sensitivity, response time, and other parameters meet the requirements. By adjusting the speed of the motor 208 or replacing different sized transmission components, seismic waveforms of different frequencies and amplitudes can be simulated, thus meeting the detection needs under multiple working conditions. The overall structure is compact and easy to operate, possessing good practicality and promotional value.
