Description

Technical Field

[0001] The utility model relates to the technical field of seismographs, and in particular to a closed levelness monitoring device applied to a seismograph. Background Art

[0002] Existing pendulum seismometers are usually three-way split structures. When in use, you need to first install the pendulum pier, level the pendulum pier, and then evenly distribute the three pendulum bodies on the pier at an angle of 120 degrees along the circumference. Finally, install a protective cover to seal the pendulum bodies to suppress the influence of external magnetic fields, temperature, and atmospheric pressure changes on the instrument. To ensure its sealing, the protective cover is usually made of invisible materials. After the protective cover is installed, the state of the pendulum bodies in the protective cover cannot be effectively observed. The seismometer is usually installed at the target point for a long time. Over time, the pendulum bodies may tilt, affecting the accuracy of the seismometer. Utility Model Content

[0003] The purpose of the utility model is: to address the above-mentioned problems, the utility model provides a closed levelness monitoring device applied to a seismograph, by leveling bubbles combined with opaque leveling liquid, so that the detection part can be detected by the monitoring device only when the cavity is in a horizontal state or the inclination angle does not exceed the maximum working inclination angle, thereby realizing real-time monitoring of the levelness of a specified device under closed conditions.

[0006] Furthermore, the detection part is a columnar structure, the bottom surface of the detection part is assembled on the bottom surface of the cavity, and there is a gap between the top surface of the detection part and the cavity. When the leveling bubble moves to the detection part, the leveling bubble causes the top surface of the detection part to expose the leveling liquid in a detectable state; when the leveling bubble moves away from the detection part, the leveling liquid enters the gap between the top surface of the detection part and the cavity and shields the detection part.

[0007] Furthermore, the top surface of the cavity is a convex structure, and the detection portion corresponds to the center of the convex structure.

[0008] Furthermore, the monitoring generating device is arranged on the top inner wall of the protective cover, and the monitoring generating device can emit detection light to the detection part.

[0009] Furthermore, it also includes a pendulum device, which can be installed in the detection space. The top surface of the pendulum device is provided with a liquid leveling structure, and the protective cover is provided with a monitoring generating device corresponding to the liquid leveling structure at the pendulum device.

[0010] Furthermore, the top surfaces of the plurality of pendulum devices are each provided with a corresponding liquid leveling structure, and the protective cover is provided with a plurality of monitoring generating devices corresponding one-to-one to the plurality of liquid leveling structures.

[0011] Furthermore, the plurality of monitoring and generating devices are all signal-connected to the control device, the control device is signal-connected to an alarm unit, and the alarm unit is controlled by the control device.

[0012] Furthermore, a plurality of monitoring generating device signals are connected in parallel to the control device.

[0013] Furthermore, the maximum working inclination angle is 1-5 degrees.

[0014] Furthermore, a visual leveling indication mark is provided at a corresponding position between the cavity and the detection portion.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] 1. The utility model uses leveling bubbles in combination with opaque leveling liquid so that the detection part can be detected by the monitoring device only when the cavity is in a horizontal state or the inclination angle does not exceed the maximum working inclination angle, thereby realizing real-time monitoring of the horizontality of the designated device under closed conditions.

[0017] 2. The liquid leveling structure of the utility model can indicate leveling under non-enclosed conditions, and cooperate with the monitoring device under enclosed conditions to realize real-time monitoring of the horizontality of the designated device.

[0018] 3. The top surface of the cavity of the utility model adopts a convex structure, so that the leveling bubble can be centered at the protrusion when the cavity is in a horizontal state or the inclination angle does not exceed the maximum working inclination angle, ensuring that the detection part can be accurately exposed to the leveling liquid and is in a detectable state.

[0019] 4.
