When the rotary switch 610 is turned from "TEST" to "OFF", the stop micro switch 630 is turned ON, the switch 0, ck foot is turned ON, the hook release micro switch 620 is turned OFF, the switch 0, cb foot is turned ON, the microprocessor module I/O detects that DP-OFF is high level, DP-KZ, DP-ON, DP-TEST is low level, the microprocessor module controls the foot to output control signal, and the motor rotates. After locking, the stop micro switch 630 is operated, the reed is not pressed down to be in an off state, and the switch 0 and the cb pin are conducted. The hook release micro switch 620 is pressed down to be in a closed state by the action reed, the switch 0, the ck foot is connected, the circuit power supply is disconnected, and the motor stops rotating.

In actual operation, the rotary switch is rotated at the rotation Kong Duixuan, the rotary switch 610 is turned ON from OFF, and different from the debugging process, when the release program is started, a release instruction sent by the outside needs to be obtained, namely, the microprocessor module waits for receiving an external communication control signal, and when the communication module obtains the release instruction, the release program is carried out, and the motor starts to rotate; the other procedures were the same.

In the whole release process, the release switch is manually closed, so that a release program can be completed, remote release control is realized by combining remote communication, and when the release switch is opened, remote release control can be realized; the motor and the wheel shaft are combined to rotate to drive the micro switch to open and close alternately, so that various control signals are generated to feed back and control the motor, a sensor is not needed to detect whether the motor rotates in place, closed-loop control is realized in an electromechanical combination mode, the design is ingenious, and the performance is reliable. When the hook is released to connect the load, limit notches are formed in two sides of the release hook, the hook is in butt joint limit in the direction of the vacancy of the hanging part, the hanging reliability is guaranteed, when the hook is released, only the release hook rotates, and the notch limit does not affect the release of the hook. The release device is sealed in multiple ways, is suitable for underwater use, and has good reliability. When the load needs to be reloaded, the rotary switch 610 is turned to the OFF position to lock.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and improvements made by those skilled in the art without departing from the present technical solution shall be considered as falling within the scope of the claims.
