Cooperation, blowout patche and lower connecting shaft are interference fitted, and the top surface of seat ring is connected to the inner wall top surface of shell, and the bottom surface of blowout patche is connected to prominent
The top surface of circle.
When buoy drifts about under the action of stormy waves, buoy can transmit the pulling force of upper section cable by the rotor of electric slip ring
Onto the lower connecting shaft being fixedly connected with the rotor, then the prominent circle by being arranged in lower connecting shaft is sequentially delivered to blowout patche, first
Rolling element, seat ring, the outer casing inner wall top surface abutted with the top surface of seat ring, by between blowout patche, the first rolling element, seat ring, shell
Cooperation born caused by buoy drift together to the pulling force of upper section cable；Buoy can be sliding by electricity to the pulling force of lower section cable
The stator of ring is transmitted on the cable end being fixedly connected with stator, which passes to the outer casing inner wall bottom abutted with the bottom surface of cable end
The pulling force caused by buoy drift to lower section cable is born by the cooperation between cable end and shell in face together, it is possible thereby to
So that upper section cable and lower section cable will not because of buoy drift and tension disconnects electrical connection.
When buoy spins under the action of stormy waves, the rotor of the upper connecting shaft and electric slip ring that are fixedly connected with buoy is solid
Surely lower connecting shaft, rotor, upper section cable, the first rolling element and the blowout patche being interference fitted with lower connecting shaft connected can revolve together
Turn, and being connected to the seat ring of outer casing inner wall top surface, the cable end being fixedly connected with stator, stator, lower section cable will not then revolve relatively
Turn, the rotor for the relative rotation being electrically connected with upper section cable and is electrically connected relatively non-rotary stator with lower section cable and still maintains
Contact is conductive, can prevent upper section cable and lower section cable from being twisted off out electrical connection because of spinning for buoy.
Therefore, when buoy spins and drifts about under the action of stormy waves, upper section cable and lower section cable will not because of by
It draws or is turned round and mutually disconnect electrical connection, ensure that the continued power of oceanographic observation instrument and reliable and stable data transmit.
