An upper input gear 26 is fixed on the intermediate shaft 21, and an upper output gear 27 is fixed on the upper end of the upper output shaft 22. The upper input gear 26 and the upper output gear 27 are meshed for transmission.

[0034] In this way, a mechanical brake is installed on the intermediate shaft. When the full-turn device does not need to work, the intermediate shaft is locked and does not rotate, so that the clutch rear transmission cannot rotate, thereby ensuring that the propeller will not drive the clutch rear transmission to rotate due to the impact of water flow, effectively preventing the rotation of parts.

[0035] like Figures 2 to 4 As shown, in this embodiment, the mechanical brake 4 includes a base 42, a brake wheel 41, a brake belt 43, a support seat 44, a brake screw 40 and two brake nuts 45;

[0037] With this arrangement, the brake wheel is clamped by the brake belt, and each shaft system in the full-rotation device is locked, so that the clutch rear transmission cannot rotate, thereby ensuring that the propeller will not drive the clutch rear transmission to rotate due to the impact of water flow, effectively preventing the rotation of parts.

[0038] Further preferably, two supporting feet 441 are arranged along the length direction of the brake belt 43; the reset member 46 includes a spring, and the two ends of the spring are respectively connected to the support seat 44 and the base 42; the two supporting feet 441 are located between the two springs; it also includes a signal device 48, the signal device 48 is installed on a brake nut 45, and the signal device 48 is used to detect the other brake nut 45; a waist-shaped hole 442 is opened on the supporting foot 441, and a locking pin 49 is installed on the base 42 and passes through the waist-shaped hole 442; a handwheel 47 is fixed on the brake screw 40.

[0039] In this embodiment, the lower input shaft 24 and the lower input gear 28 are integrally formed.

[0041] When the ship equipped with the above-mentioned full-revolving device is moored, the clutch cuts off the power between the input flange and the intermediate shaft, and then turns the handwheel. The handwheel drives the two brake nuts to approach each other through the thread, so that the brake belt holds the brake wheel tightly, and the brake wheel locks the intermediate shaft. The intermediate shaft 21, the upper output shaft 22, the vertical shaft 23, the lower input shaft 24, the propeller shaft 25 and the propeller blades 33 are locked to ensure that the propeller stops rotating, thereby achieving the internal parts of the full-revolving propeller device not rotating and the safe mooring of the ship.
