Existing seismic well resistivity demonstration devices are unable to withstand external factors such as vibration and wind, which can cause the equipment to shift, shake, or tip over, affecting the accuracy of measurements.
The device employs a clamping and fixing component and a waterproof component. The clamping and fixing component uses a motor-driven bidirectional threaded rod to move the clamping plate to fix the device, while the waterproof component uses a limiting slider and a groove to prevent rainwater from seeping in.
It effectively prevents the equipment from shifting or tipping over due to vibration and wind, ensuring the stability of the measurement, and preventing rainwater from entering the equipment, thus extending the equipment's service life.
