Durable Push Rod Drain Corrosion-Resistant Panoramic Borehole Inspection Camera for Marine Geology Surveys
It is applicable to fields such as engineering geology, hydrogeology, geological mineral exploration, mining departments, concrete, pile foundation underground pipelines, and water wells. The borehole inspection television is a primary equipment for obtaining clear images in underwater environments in real time, serving as a reliable assistant for well drilling, well repair, and retrieval of objects fallen into wells, capable of transmitting the conditions underground to the ground surface. Additionally, the borehole inspection television can be widely applied to water well inspections (such as detecting well wall damage, misalignment, fractures, cavities, and objects fallen into wells), underwater surveying, underwater operations, diving exploration, sewage treatment, aquaculture, and other areas.

Safety Operating Procedures for Electric Winches
The electric winch should be installed on a flat, solid surface with good visibility. If the ground is slippery, ground anchors must be used to ensure the winch is firmly secured to the ground, preventing slippage caused by the counterforce generated when the probe ascends or descends in the well.
The centerline of the electric winch's guide pulley should be vertical and overlap with the vertical centerline of the wellhead. If a wellhead pulley is added at the wellhead, the distance between the electric winch and the wellhead pulley should generally not exceed 10 meters.
Before commencing operations, inspect the cable for any damage. Confirm that the winch's lifting direction is consistent with the required operational direction. Ensure that both the forward and reverse rotation of the wellhead pulley are smooth. The speed control switch must be returned to its initial position before starting the machine.
After starting the machine, place the left hand on the start button (to quickly press the stop button in case of an emergency). Slowly rotate the speed control knob with the right hand to start the winch smoothly. When stopping the machine, the speed control knob must be returned to its initial position.
Once the probe is inserted into the wellhead, the lowering and retraction speed must not be excessive, not exceeding 3 meters per minute. This prevents cable tangling.
Method to zero the depth counter: Start the winch to slowly pull out the probe and insert it into the wellhead. If the depth data displayed on the screen is not zero at this point, press the "Zero" button above the display to reset the displayed length to zero.
The cable on the drum must be neatly arranged. During operations, at least five turns of cable must be retained. No personnel are allowed to cross over the electric winch cable during operations.
During winch rotation, operators are strictly prohibited from leaving their posts without authorization. The left hand must be placed next to the start button, and the right hand must not leave the speed control switch knob of the winch.
In the event of a sudden power failure during operations, immediately press the stop button, and return the speed control knob to its initial position.
