The controlled switch is opened, and the motor 7 is powered on and starts to rotate; the controlled switch is closed, and the motor 7 is powered off and stops rotating. Since the motor 7 is equivalent to a large inductance on the circuit, its current will not disappear immediately, and a freewheeling diode 27 needs to be added to prevent the components from being burned out. The mechanical relay 29 handle 33 presses and pops up the corresponding IO pin of the microcontroller 30 to input low/high level, so when the handle 33 exits the V-slot 19, a rising edge will trigger an external interrupt. In order to ensure reliable release, the microcontroller 30 Detecting an external interrupt, each time it is released, when the motor 7 completes one revolution, the microcontroller 30 executes the shutdown of the motor 7 in the interrupt service routine to ensure that the motor 7 rotates at least one revolution, which also ensures that the heavy object can be released. Referring to FIG. 14 , it is a schematic diagram of the cooperation between the handle 33 and the V-shaped groove 19 .

The release workflow is shown in Figure 11. After the system is powered on, it is in the waiting state. The user sends a wake-up command through the serial port to wake up the system. After the user sends and confirms the standby time through the serial port, the system starts to standby. After the standby time specified by the user, the motor starts. Rotate, release the heavy object, and the system returns to the waiting state again.

The head 12 is rotated, and the screw 23 is lifted. At this time, the connecting hook 13 and the releasing hook 15 are in the positions shown in FIG. 13 . Under the action of the gravity of the heavy object, the release hook 15 is pulled down, which drives the connecting hook 13 to rotate further, and the closing ring 34 is no longer closed, so as to ensure the smooth decoupling of the heavy object.

The invention is small in size, with a diameter of 9.4cm and a length of 38.2cm, and can be easily mounted on various instrument platforms; the depth of application is deep, up to 3500m; the shaft rod 9 of the part that is squeezed by seawater and needs to rotate is equipped with a radial bearing 10 and a thrust force Bearing 8, to prevent it from being difficult to rotate due to excessive squeezing and friction of sea water; use the rotating head 12 to lift the screw 23, and disengage the release hook 15 to release the heavy objects; after one use, you only need to set the standby time through the serial port again.
