This invention discloses a movable straightening device, including a placement platform, a mounting frame on the placement platform, a fixed frame on the mounting frame, and a motor mounted on the fixed frame. The fixed frame contains a first internal gear ring, and a second rotating rod is fixedly connected to the motor. A first actuating plate is on the second rotating rod. A moving mechanism and a driving heat dissipation mechanism are located at the bottom of the placement platform, and a braking mechanism is connected to the driving heat dissipation mechanism. A marking mechanism is provided on the mounting frame. When the motor rotates in the reverse direction, water from the first water tank enters the fixed pipe, causing the friction block to press down on the moving wheel, thus acting as a brake. Simultaneously, water also enters the hollow disc, causing the fan blades to rotate and accelerating airflow at the moving wheel, achieving a heat dissipation effect. Due to the heat dissipation holes on the friction block, air can pass through more effectively, and the heat generated by braking can be carried away more efficiently by changing the airflow speed.

The rotating system is sleeved on the rotating shaft system to form a lubricant cavity; on the same side of the lubricant cavity, at least two sealing assemblies are arranged between the rotating system and the rotating shaft system, and the at least two sealing assemblies are arranged along the axial direction of the rotating shaft system. In this way, two or more sealing structures can be formed on the same side of the lubricant cavity, the probability of lubricant flowing out of the lubricant cavity is reduced, and the sealing performance of the lubricant cavity is improved. The at least two sealing assemblies can prevent the lubricant in the lubricant cavity from flowing out along the axial direction of the rotating shaft system, so that the lubricant cannot infiltrate into the inner surface of the brake hub, the brake failure of the mechanical equipment is avoided, and the safety of the mechanical equipment is improved.

This utility model discloses an emergency braking system for rigid sails, relating to the field of braking technology for rigid sail transmission systems. It includes a hydraulic pump, an electromagnetic directional valve, a high-pressure relief valve, and a hydraulic oil tank. The hydraulic pump's suction port is located inside the hydraulic oil tank. The hydraulic pump's outlet is connected in two directions via hydraulic hoses: one direction connects to the inlet of the high-pressure relief valve, and the other direction connects to the inlet of the electromagnetic directional valve via a three-way connector. The outlet of the high-pressure relief valve is connected to the hydraulic oil tank via a hydraulic hose. The return port of the electromagnetic directional valve is connected to the hydraulic oil tank via a hydraulic hose. The advantages are: the system does not rely on external power; when the ship loses power, the power of the sail propelled by the sea breeze triggers the hydraulic brake, effectively preventing the sail from dragging the gearbox and motor; the bidirectional high-pressure hydraulic pump ensures reliable braking regardless of the sail's direction; the relief valve is flexible and adaptable to different ships, sails, and sea conditions, making it highly practical.
