The technical solution of the utility model is as follows:
the utility model provides a cable shaft watertight fittings, includes the gasbag, its special character lies in: the air bag is annular after being unfolded, a first sealing ring which is arranged up and down is arranged on the outer edge surface of the air bag, a second sealing ring which is coaxially arranged is arranged on the bottom surface of the air bag, an inflating nozzle is arranged on the inner circular surface of the air bag and connected with an air pump through an air pipe, the air pump is connected with a storage battery through a relay, the signal input end of the relay is connected with a processor, and the signal input end of the processor is connected with a water sensor and a communication module.
Furthermore, a rain shielding sheet is arranged at the position, corresponding to the central hole, of the top of the air bag, so that rainwater is prevented from falling onto the air pump, the storage battery and the power supply through the central hole of the air bag.
Further, this cable shaft prevention of seepage water device still is equipped with and increases the frame, air pump, treater and battery fixed mounting increase a top surface, increase the frame and support air pump, treater and battery in lining well lid top, avoid the ponding of deposit on lining well lid to get into air pump, treater and battery.
Further, the processor model is ARM Cortex-M.
The utility model has the beneficial effects that:
1. because the first sealing ring arranged up and down is arranged on the outer edge surface of the air bag, the second sealing ring arranged coaxially is arranged on the bottom surface of the air bag, the upper end surface and the lower end surface of the air bag after the air bag is inflated and expanded are respectively attached to the bottom surface of the main well cover and the top surface of the lining well cover, the outer circular surface is attached to the wall of the main well, the first sealing ring seals between the outer circular surface of the air bag and the wall of the main well, and the second sealing ring seals between the bottom surface of the air bag and the top surface of the lining well cover, so that rainwater is prevented from flowing into a cable channel through a gap on the edge of the lining well cover.
2. When the rain falls, rainwater falls to the lining well cover through the opening hole of the main well cover or the edge gap of the main well cover, and the water logging sensor contacts the rainwater deposited on the lining well cover to control the air pump to open; before rainfall, the operating personnel control the air pump to be started through the communication module through the background terminal equipment. And the inflation is timely and reliable, and the effective water seepage prevention of the cable well is ensured.
