[0002] The VP wide-band vertical pendulum inclinometer is a new type of cave deformation observation equipment developed based on the VS inclinometer. Its resolution of better than one thousandth of an arc second and widened bandwidth not only allow for the observation of earth tilt tides, but also allows for the recording of more seismic information, such as slow and long-period earthquakes. As the most advanced cave deformation observation equipment currently available, the VP inclinometer boasts high observation accuracy and strong cave adaptability. It has been widely used across China and has become one of the most widely used mainstream cave deformation observation instruments in the network. However, due to its short service life, high accuracy, and complex internal design, the instrument presents significant challenges in maintenance.

[0003] The VP inclinometer measurement system maintenance process includes the following steps: Step 1: Measure the DC power supply to eliminate faults in the power supply board, power supply line, and contact points; Step 2: Measure the tungsten wire resistance to eliminate the possibility of the suspension block falling or the tungsten wire being disconnected; Step 3: Measure the detection signal to eliminate faults in the amplifier board; Step 4: Measure the output signal to eliminate faults in the zero adjustment board.

[0004] The existing VP inclinometer measurement system is manually inspected step by step using multiple devices. Technicians are required to judge the condition of the VP inclinometer based on their maintenance experience, which results in long inspection time and low efficiency. Utility Model Content

[0029] A quick maintenance device for a VP inclinometer includes a housing 1, a processor is provided in the housing 1, a digital display screen 2 electrically connected to the processor is installed on the front face of the housing 1, and a power interface 3, a direction selection switch 7, a signal connection aviation plug 5 and a power output aviation plug 6 are installed on the rear face of the housing 1.

[0030] The power interface 3 is provided with a power switch 4 and a power adapter. A ±12VDC signal power board connected to the power interface 3 is provided inside the housing 1. The signal power board is electrically connected to the power output aviation plug 6.

[0031] The power interface 3 is electrically connected to the digital display screen 2 through a power adapter.

[0032] The processor includes a control module and a data processing module, and the control module is electrically connected to the data processing module.

[0033] The direction selection switch 7 is electrically connected to the control module, and the signal connection aviation plug 5 and the digital display screen 2 are electrically connected to the data processing module respectively.

[0034] The direction selection switch 7 is a switch for selecting the north-south and east-west components of the VP inclinometer sensor, and is used for detection of different component sensors.

[0035] A handle 9 is installed on the upper surface of the shell 1, and the handle 9 is provided with anti-slip grooves, which is convenient for testing the working conditions of the instrument at different positions in the observation room inside the cave and the external recording room.

[0036] The housing 1 is provided with ventilation holes 8 symmetrically arranged on both sides of the handle 9 .

[0037] An anti-slip pad is provided at the bottom of the housing 1 .

[0038] This device is connected to an external 220V AC power supply through the power supply interface 3, which is converted into ±12V DC power by the ±12VDC signal power supply board, and then powered by the zero adjustment board at the pendulum end in the cave through the power output aviation plug 6. After further conversion by the zero adjustment board, it is converted into ±5V DC power to power the sensor on the pendulum body; the 220V AC power is converted into 24V DC power by the 24V power adapter to power the digital display screen 2.

[0039] The data processing module on the processor of the device receives the detection signal amplified by the sensor through the signal connection aviation plug 5 and displays it on the digital display screen 2.

[0040] Example 2

[0041] like Figure 3 and Figure 4 As shown, a protective shell 10 is installed on the outside of the processor, and a heat dissipation fin 11 is provided on the outer peripheral surface of the protective shell 10 to facilitate heat dissipation of the processor when it is working for a long time.

[0046] When the temperature sensor 13 detects that the internal temperature reaches the lower threshold temperature, the control module controls the heating wire 14 to turn on, and when it reaches the upper threshold temperature, the heating wire 14 stops working; during actual operation, the fan threshold temperature is higher than the upper threshold temperature of the heating wire. This working mode uses heating to dissipate water vapor, keeping it dry and achieving a moisture-proof effect.
