The present disclosure provides a trawler with a fishing and conveying device and a fishing method, and belongs to the technical field of trawlers. The trawler of the present disclosure includes a hull structure and two fishing devices, wherein the fishing device includes a first rotary rod, a second rotary rod, a fixing frame and a fish suction mechanism, the first rotary rod is hinged at the bow of the hull structure, a fishing net is connected on the first rotary rod, the second rotary rod is hinged at the stern of the hull structure. The present disclosure is capable of realizing continuous fishing and directly conveying the fish onto the trawler, and thus is simple to operate.

A mine explosion-isolating hoisting device with a built-in type permanent magnet motor includes a spindle fixed on the ground; a permanent magnet motor stator fixed on the spindle; a drum rotating relative to the spindle, the drum surrounding the spindle circumferentially; and a permanent magnet motor external rotor fixed by a spoke plate and rotating relative to the spindle; the drum is connected to the permanent magnet motor external rotor via an isolating disc; and a radial distance between an outer circumferential surface of the permanent magnet motor external rotor and an inner wall of the drum is greater than a preset value.

A lifting cabinet includes a transmission assembly and a power unit for raising and lowering a shelf. The transmission assembly comprises a first transmission unit, comprising a screw rod which is connected with a driving device and a sliding piece which is connected with the lifting shelf, and the sliding piece is coupled to the screw rod. The screw rod rotates under the action of the driving device and drives the sliding piece to move back and forth along the axis of the screw rod; and then the sliding piece drives the lifting shelf to move up and down. For the lifting cabinet and the power unit thereof, the transmission assembly converts a rotary motion outputted from the driving device into a linear motion through the cooperation between the screw rod and the sliding piece, and a greater axial force is thereby outputted. Thus, a relatively small motor with a lower output torque can be used in the lifting cabinet to drive a lifting shelf of the same weight when compared to the conventional lifting cabinet, and the problem of large motor in conventional lifting cabinet taking up too much space is thereby solved.

An automatically opening and closing inflatable holiday ornament includes a box that has a base, a plurality of side panels hingedly connected to the base, and a top portion connected to each of the plurality of side panels. The ornament further includes a motor, a plurality of pull cables, such that each of the plurality of pull cables has a first end operatively connected to the motor and a second end connected to one of the plurality of side panels. The ornament also includes a first blower, an inflatable disposed in the box and surrounding the first blower such that operation of the first blower blows air into the inflatable to inflate the inflatable, and a controller operatively connected to the motor and to the first blower such that the controller controls operation of the motor and the blower.

A robot system for maintenance of a building façade with an irregular façade surface is provided. The robot system includes a platform cooperating with a least four pairs of cables for positioning the platform at a distance from a building façade. At least one robot arm is situated on the platform, and includes an adaptor positioned at a distal end thereof for holding and manipulating a building façade maintenance tool. An actuator drives the cables to move the platform to any arbitrary position along the building façade. A controller cooperates with the actuator to instruct the actuator to drive the cables and to control movement of the robot arm, such that driving the actuator and movement of the robot arm is coordinated by the controller; any position deviations in the platform are compensated for by positioning or movement of the robot arm.

A baler includes a body, and a wrap system that is attached to the body. The wrap system is operable to support a roll of wrap material in an installed position. A cover is attached to the body, and is moveable between an open position and a closed position. When in open position, the cover provides access to the wrap system from an exterior location. When in the closed position, the cover encloses the wrap system from the exterior location. The baler includes a lift system attached to the body. The lift system is concealed between the body and the cover when the cover is disposed in the closed position. The lift system is positioned below the cover when the cover is disposed in the open position. The lift system raises the roll of wrap material into the installed position.
