Description

Technical Field

[0001] The invention relates to the technical field of monitoring equipment, and in particular to a karst collapse monitoring device and a construction method. Background Art

[0002] Karst collapse refers to the sudden deformation and destruction of the loose soil covering the karst caves under the action of external forces or human factors, which often results in the formation of conical collapse pits. This phenomenon mainly occurs in areas where soluble rocks such as carbonate rocks, calcareous clastic rocks and salt rocks are distributed. The formation of karst collapse is due to the fact that the groundwater level changes to a certain extent, breaking the three-phase mechanical equilibrium system of solid, liquid and gas, causing the overlying loose sediments to collapse suddenly.

[0003] Karst collapse monitoring devices are technical systems used to monitor the ground stability of karst areas in real time. These devices can detect small changes on the surface and underground, predict potential collapse events, and take disaster prevention and mitigation measures in a timely manner. Karst collapse monitoring devices usually include a variety of sensors and monitoring equipment that can measure relevant parameters such as ground displacement, groundwater level changes, soil moisture, vibration, etc.

[0004] The karst collapse monitoring device in the prior art mainly uses solar panels to supplement electric energy. The solar panels of the karst collapse monitoring device in the prior art are fixed, and are unfolded when not in use at night. At night, there are birds or other biological activities. Therefore, the solar panels are easily damaged during long-term unfolding, thereby causing economic losses. Summary of the invention

[0021] A construction method for a karst collapse monitoring device includes the following construction methods:

[0022] Step 1: Dig a hole in the soil first, and then use the bottom cone to insert the entire embedded mechanism into the hole;

[0023] Step 2: Place the preloading rod between multiple preloading plates, twist the moving plate upwards, thereby driving the folding frame to open, and then the preloading plate can move toward the middle to squeeze the preloading rod, thereby completing the preloading;

[0024] Step 3: Pour cement in the hole, immerse the embedded mechanism, and use the embedded mechanism to strengthen the tensile and shear resistance of the device after installation;

[0025] Step 4: After the cement dries, the installation is completed.

[0026] Working principle: First, dig a hole on the ground, then turn the bottom cone downward and insert the bottom cone into the soil. At this time, screw the movable disk downward so that the folding frame bends outward, and then drives the outer box to move outward. The outer box drives the limit plate and then drives the pressure rod to move outward, so that the pre-tightening plate moves to both sides. At this time, insert the pre-installed rod between multiple pre-tightening plates. At this time, screw the movable disk upward so that the folding frame can be unfolded, and the outer box moves toward the middle, thereby driving the pressure rod to move toward the middle, and then the pre-tightening plate can be moved toward the middle, and then the pre-installed rod can be clamped to complete the installation of the height connection adjustment mechanism. At this time, concrete is poured into the inside of the hole, so that the pre-embedded mechanism can be used to strengthen the tensile and shear resistance of the device after installation;

[0027] When the solar panel is folded, the motor is started to drive the threaded column to rotate. After the threaded column rotates, it can drive the inner rod to move downward. Therefore, after the inner rod moves downward, it can drive the central axis to move downward. Since the fixed plate is stationary, the connecting rod will not move downward. The top of the connecting rod will rotate toward the middle, and then it can drive the solar panel to fold toward the middle. Therefore, when not in use at night, the solar panel can be folded up to prevent birds from flying or landing at night and causing damage to the solar panel. When the inner rod moves downward, it can drive the fixing ring to move downward. The fixing ring moves downward and drives the driving rod to move downward, and then it can drive the monitoring control box to move downward, so that the monitoring control box can be easily inspected and repaired. Therefore, there is no need to climb up to the monitoring control box using tools, thereby eliminating safety hazards.

[0028] The present invention provides a karst collapse monitoring device and a construction method, which have the following beneficial effects:

[0029] 1. The present invention drives the central axis to move downward by contracting the height connection adjustment mechanism, thereby driving the two solar panels to fold, so that the solar panels can be folded when not in use at night, shortening the unfolding time, thereby reducing the probability of damage to the solar panels by birds or other creatures, thereby increasing the service life of the solar panels and reducing economic losses.

[0030] 2. The present invention pre-installs the height connection adjustment mechanism through the embedded mechanism, so as to prevent the device from tipping over when the cement is not dry. There is no need to cast the base first and then install the device after the cement base is dry. The device can be installed successfully at one time, thus saving time and effort and improving installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
