Description

Technical Field

[0001] This invention relates to the field of earthquake precursor monitoring technology, and in particular to an underground radon gas monitoring system for earthquake precursor monitoring. Background Technology

[0002] As we all know, earthquakes are extremely dangerous. Monitoring earthquake precursors—that is, abnormal phenomena that occur before an earthquake—has become an important and hot topic in earthquake research. Underground radon monitoring systems are used by technicians, but existing systems only meet basic needs and still have the following areas for improvement and optimization:

[0003] Firstly, existing underground radon monitoring systems cannot adapt to the complex and diverse underground terrain because their monitoring angle and orientation cannot be adjusted underground, thus reducing the monitoring efficiency and effectiveness of the radon monitoring system.

[0004] Secondly, existing underground radon monitoring systems cannot effectively adjust the descent depth of radon detectors during operation, making it inconvenient to monitor at different depths and resulting in incomplete monitoring. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an underground radon gas monitoring system for earthquake precursor monitoring. By combining an intelligent monitoring device and a lifting device, it overcomes the deficiencies of existing technologies and effectively solves the problems that existing underground radon gas monitoring systems cannot adapt to complex and diverse underground terrain environments and are not convenient for monitoring at different depths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ground radon gas monitoring system for earthquake precursor monitoring includes a frame with braked casters fixed at each of the four corners of the bottom. A cover is fixed on the top outer wall of the frame. A disc is connected to the cover via a lifting device, and an intelligent monitoring device is installed on the disc.

[0008] The intelligent monitoring device includes cameras arranged in a ring on the outer wall of the disc, an image processor and a microcontroller fixed in sequence on the bottom outer wall of the disc, a turntable connected to the disc via a rotating mechanism, an adjustment block hinged to the turntable, a radon detector fixed to the adjustment block, and an electric push rod hinged to the bottom of the turntable.

[0009] By adopting the above technical solution, the underground environment is monitored by a camera and the image signal is transmitted to the image processor for intelligent processing in a timely manner. The image processor then transmits the processed signal to the microcontroller, which ultimately executes the signal to control the rotating mechanism and the electric push rod to adjust the angle and orientation of the radon detector to a suitable position. This allows the system to adapt to the complex and diverse underground terrain environment, thereby improving the monitoring efficiency and effectiveness of the radon monitoring system.

[0010] Preferably, the rotating mechanism includes a stepper motor fixed to the outer wall of the bottom of the disk, a drive gear fixed to the output shaft of the stepper motor, a rotating shaft rotatably mounted on the inner wall of the center of the disk, and a driven gear fixed to the rotating shaft.

[0011] The bottom end of the rotating shaft is fixed to the outer wall of the top center of the turntable, and the driving gear meshes with the driven gear;

[0012] By adopting the above technical solution, it is easy to control the radon gas detector to rotate to different positions for real-time detection.

[0013] Preferably, the lifting device includes a threaded rod rotatably mounted inside the machine cover, a T-shaped lifting sleeve screwed onto the threaded rod, and an electric control assembly;

[0014] The electric control assembly includes a worm gear fixed to the upper part of the threaded rod, a servo motor fixed to the outer wall of the top of the machine cover, and a worm fixed to the output shaft of the servo motor and meshing with the worm gear.

[0015] By adopting the above technical solution, the screw rod is rotated by an electric control component, and the T-shaped lifting sleeve drives the radon detector below to descend continuously underground. This allows for precise adjustment of the descent depth of the radon detector, facilitating monitoring at different depths and making the monitoring more comprehensive and thorough.

[0016] Preferably, a limiting port is provided on the frame, and the outer wall of the T-shaped lifting sleeve is slidably connected to the inner wall of the limiting port;

[0017] By adopting the above technical solution, it is easy to limit the movement of the T-shaped lifting sleeve and ensure that it moves in a straight line.

[0018] Preferably, the output shaft of the electric actuator is hinged to the bottom of the adjustment block, and the camera, image processor, microcontroller, radon detector, electric actuator and stepper motor transmit signals wirelessly.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. An intelligent monitoring device is installed, which uses a camera to monitor the underground environment and transmits the image signal to the image processor for intelligent processing. The image processor then transmits the processed signal to the microcontroller, which ultimately executes the signal to control the stepper motor and electric push rod to adjust the angle and orientation of the radon detector to a suitable position. This allows it to adapt to the complex and diverse underground terrain environment, improving the monitoring efficiency and effectiveness of the radon monitoring system.

[0021] 2. Equipped with a lifting device, the screw rod is rotated by an electric control component. Under the limit of the limit port, the T-shaped lifting sleeve drives the radon detector below to descend continuously underground. It can effectively adjust the descent depth of the radon detector, making it convenient to monitor at different depths, and making the monitoring more comprehensive and accurate.
