[0071] The first watertight socket 202 is arranged in the second end cover 201 along the axial direction of the shell 100. The first watertight socket 202 is an electrical socket used in a waterproof and moisture-proof environment. The first socket cooperates with the second end cover 201 to isolate the inside of the shell 100 from the outside of the shell 100. The two ends of the first watertight socket 202 are respectively connected to the input end of the motor 401 and the control module 500, so as to facilitate disconnection of the motor 401 and the control module 500 during maintenance.

One end of the second watertight socket is connected to the motor controller, and the other end is connected to the first watertight socket 202 through a watertight cable. Optionally, the second watertight socket is provided in plurality.

[0084] The release command is controlled by the shore station system, and the shore station system sends the command via satellite to the satellite terminal of the wave energy autonomous glider surface craft, and transmits the signal to the rudder control board through a watertight cable, and then to the motor controller by the watertight cable. Finally, the motor controller processes the signal and transmits the release command to the motor 401. After receiving the command, the motor 401 controls the output end of the motor 401 to drive the push rod 305 and the extension part 307 to move into the shell 100 through the connecting part 403, so that the rotation limit of the release part 304 is released, and then the rotation limit of the limit part 303 is released, and the limit port is opened to release the device to be released, completing the release task.

[0085] The present application provides a miniature underwater remote control release device, which is installed on a surface floating device to release a device to be released. By separating the control module 500 from the outside of the shell 100, the internal structure of the shell 100 is simplified and the release reliability is guaranteed, thereby reducing the carrying burden of the surface floating device; the device to be released is stably fixed by the cooperation of the release seat 302, the limit member 303 and the release member 304; the rotation of the release member 304 is limited by the cooperation of the limiting member 306 and the extension member 307, thereby achieving the purpose of stably limiting the device to be released; the limit gap between the limiting member 306 and the extension member 307 is stably maintained by the wear-resistant member 308; a reserved gap is set between the inner wall of the slot and the connecting member 403 to ensure that a stable axial driving force is still provided when there is a deviation between the axis of the telescopic member and the axis of the push rod 305; and a contact plane is set to increase the contact area to prevent the release member 304 from slipping.

[0086] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0087] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the same. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present application. They should all be included in the scope of the technical solutions for which protection is requested in the present application.
