The utility model provides an offshore portal crane, and relates to the technical field of cranes, and the offshore portal crane comprises a main beam, two supporting legs, an electric winch module, two main hooks and two ground beams; the top ends of the two supporting legs are fixedly connected to the two ends of the main beam respectively, the bottom ends of the two supporting legs are fixedly connected to the two ground beams respectively, the supporting legs are perpendicular to the ground beams, the ground beams are in a long strip shape, and the linear direction of the ground beams is perpendicular to the linear direction of the main beam. The electric winch module is connected to the main beam; the two main hooks are connected with the electric winch module through steel wire ropes, and the electric winch module retracts and releases the steel wire ropes to drive one of the main hooks to ascend or descend or drive the two main hooks to ascend or descend synchronously. The steel wire rope gathering phenomenon is avoided, the height deviation of the two main hooks is adjusted, and rapid and stable offshore hoisting operation is achieved.

The invention discloses a rope type rotating weir and a control method thereof, and the rope type rotating weir comprises a weir plate which is rotatably arranged in a water passing channel and divides the water passing channel into an upstream and a downstream; a fixed pulley; a deflecting pulley; one end of the traction rope is connected with the weir plate, and the other end sequentially bypasses the fixed pulley and the steering pulley to be connected with the driving device; and the driving device is used for winding and unwinding the traction rope, so that the traction rope can drive the weir plate to rotate. In the process of increasing the opening degree of the weir plate, the gravity of the weir plate is beneficial to continuous increase of the opening degree. And in the process of reducing the opening of the weir plate, the opening can be continuously reduced under the action of water pressure. Therefore, based on the rope type rotating weir, the opening degree of the weir plate can be controlled by controlling the winding and unwinding amount of the traction rope, and the precision reliability and controllability are better. And no matter the opening degree is increased or decreased, the pressure or water pressure of the weir plate is beneficial to rotation of the weir plate, and the driving device is more labor-saving, so that the advantage of low energy consumption is achieved.

This invention discloses a modular, customizable motor system and its combination method, belonging to the field of motor system technology. It includes a power module, a functional module, and a control module. The power module includes a stator, a rotor, a pair of end caps, and a housing. The stator windings are fixedly connected inside the housing. The rotor passes through the central area of ​​the stator, and its two ends are rotatably connected to both ends inside the housing via bearings. The functional module includes a rear cover, several crown spring connectors, and an equal number of pin-type copper terminals. The control module is fixedly installed inside the rear cover and fixedly connected to several crown spring connectors. The pair of end caps are fixedly connected to both ends of the housing, with one end cap fixedly connected to the rear cover. The terminals of several pin-type copper terminals are fixedly connected to the end of the stator near the rear cover. The pin-type copper terminals are sequentially inserted into the crown spring connectors, achieving fast, reliable, and reversible electrical connections, solving the problems of poor soldering and difficult maintenance in traditional methods.
