Description

Technical Field

[0001] The utility model relates to the field of geological disaster monitoring and prevention, in particular to a structure deformation monitoring intelligent electrode self-adaptive position and posture correction device. Background Art

[0002] Geological hazard monitoring is crucial for protecting people's lives and property and maintaining social stability. Accurate, real-time geological hazard monitoring is crucial for disaster warning, risk assessment, and emergency response. Providing early warning before a disaster strikes plays a crucial role in protecting people's lives and property.

[0003] Chinese patent publication number CN202122281772.5 discloses an electrode device for monitoring geological hazards, dams, and tunnel safety based on the resistivity method. The device comprises a tapered threaded electrode, a drilling expansion assembly mounted at the end of the tapered threaded electrode, and a locking and adjusting assembly mounted on the tapered threaded electrode. The end of the tapered threaded electrode, distal from the drilling expansion assembly, is connected to a main cable. The drilling expansion assembly is adapted to drill and secure the hole within the ground. The locking and adjusting assembly is adapted to control the tension between the drilling expansion assembly and the borehole wall within the ground. This device boasts strong coupling between the electrodes and the soil at the target electrode monitoring point, is less susceptible to human and natural factors, and offers high monitoring accuracy. Furthermore, the main cable is buried underground, preventing accidental cable breakage caused by leakage from the electrode tip and cable during long-term monitoring, thus ensuring the validity of the monitoring data.

[0004] Based on a search of the aforementioned patents and in conjunction with existing devices, it was discovered that the soil coupling at the electrode monitoring point is high and low when used in this device. This device is unable to continue adaptively adjusting its position and posture when subjected to sudden, strong external forces, resulting in displacement. This is unable to maintain the soil coupling at the monitoring point, resulting in invalid or unmeasured measurement data. Furthermore, it is unable to maintain the validity of monitoring data even when affected by human and natural factors. Therefore, improvements to existing electrodes are urgently needed to address these issues. Utility Model Content

[0005] The purpose of this utility model is to utilize the GNSS (Global Navigation Satellite System) module to intelligently extend a telescopic electrode in the direction of displacement when the main electrode is displaced, and to adaptively correct the position and attitude to expand the range of measurement data and enhance the accuracy and reliability of measurement, thereby providing an intelligent electrode adaptive position and attitude correction device for structural deformation monitoring.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] A structural deformation monitoring intelligent electrode adaptive position and posture correction device, comprising a GNSS antenna, a large circuit box, a small circuit box, and a motor structure for realizing a three-stage telescopic structure;

[0008] The large circuit box has a built-in battery box and control circuit box. The GNSS antenna is fixed on the top of the large circuit box. The side of the large circuit box close to the control circuit box is equipped with an LED light trough, the first aviation port, the second aviation port and the GNSS line access port. A through hole is provided in the center of the bottom side, which is connected to the top cover of the small circuit box and is used to connect the control circuit box to the motor drive circuit box. The motor drive circuit box is placed in the small circuit box.

[0010] Further, the first telescopic motor device has a first motor housing, the second telescopic motor device has a second motor housing, and the third telescopic motor device has a third motor housing;

[0012] Furthermore, the lower ends of the first third-level solid brass rod, the second third-level solid brass rod and the third third-level solid brass rod are respectively connected with the first pagoda drill bit, the second pagoda drill bit and the third pagoda drill bit by means of threads.

[0013] Furthermore, the first and third level solid brass rods extend from the ends of the first and second level internal threaded brass tubes, the ends of the first and second level brass tubes are sleeved with the top ends of the first and second level internal threaded brass tubes, and then the top end of the first and second level brass tubes is fixed to the first motor housing, and the lower ends of the first and third level solid brass rods are respectively connected to the first pagoda drill bit using threads.

[0014] Furthermore, the first motor control wire and the first telescopic electrode lead, the second motor control wire and the second telescopic electrode lead, and the third motor control wire and the third telescopic electrode lead on the sides of the first motor housing, the second motor housing and the third motor housing are connected to the lower end of the small circuit box.
