The invention relates to a nursing pollutant collecting device. The nursing pollutant collecting device comprises a box body, wherein a throwing hole is formed in the middle of the top surface of thebox body; three vertical tubes are uniformly arranged on the lower portion of the inner end of the throwing hole; the vertical tubes are made from transparent plastic materials and are distributed upand down; a transverse partition plate is arranged between gaps of adjacent two vertical tubes; the top surface and the bottom surface of the partition plate are in contact with and matched with the end surface of the corresponding vertical tube, separately; the three vertical tubes are fixedly connected to the inner part of the box body through a first bracket; a first through hole is formed in the upper side of the right end surface of the box body; a first transverse rod is arranged in the first through hole; the inner end of the first transverse rod is fixedly connected to the right end ofthe partition plate on the upper portion; a round leaking hole is formed in a position, close to the left end, of the upper portion of the partition plate; the leaking hole can communicate with the vertical tube; and transverse hydraulic telescopic rods are arranged at the left and right ends of the partition plate on the lower portion. The nursing pollutant collecting device can be helpful for medical staff to finish ultraviolet disinfection of nursing pollutants quickly, and the staff can be fully prevented from being in contact with the pollutants when the pollutants are bagged and tied bythe nursing pollutant collecting device.

The invention belongs to the technical field of electric dragging transmission and particularly relates to a roller-shaped straight lien sensing dragging motor performance testing mutual feedback device for track traffic. The device comprises a roller-shaped secondary part, an arc straight line sensing motor primary part, a rotating sensing motor, a number one current transformer, a number two current transformer, a flywheel coupler, a primary base, a rotating coder and a torquemeter. The arc straight line sensing motor primary part is fixed on the primary base, the rotating coder is arranged on one side of the roller-shaped secondary part, the rotating coder, the roller-shaped secondary part, the flywheel coupler, the torquemeter and the rotating sensing motor are connected together in series through coupling joints, an alternating current end of the number two current transformer is connected with the rotating sensing motor, and an alternating current end of the number one current transformer is connected with the arc straight line sensing motor primary part. The device has the advantages of being high in efficiency, energy is saved, working condition measuring is complete, high-speeding working condition measuring and electromagnetic force measuring are complete, conversion after measuring is of no need, size is small, occupied space is small, and the device is suitable for being used indoors.

The invention discloses a variable air gap disc-shaped linear induction traction motor high-speed mutual feedback table for track traffic. The device comprises a disc-shaped secondary device, a linear induction motor primary device, a rotary induction motor, a No.1 converter, a No.2 converter, an umbrella-shaped coupler, a primary base, a secondary support table, a rotary coder, a torque meter and a fly wheel. The linear induction motor primary device is fixed on the primary base; the disc-shaped secondary device is rigidly linked with a shaft penetrating through the disc-shaped secondary device; the secondary support table is linked with the shaft by a bearing; the rotary coder is linked with a shaft penetrating through the rotary coder by a bearing; the umbrella-shaped coupler, the fly wheel, the torque meter and the rotary induction motor are serially connected together by a connection shaft in sequence. The No.2 converter is connected with the rotary induction motor; the No.2 converter is connected with the linear induction motor primary device. The variable air gap disc-shaped linear induction traction motor high-speed mutual feedback table for the track traffic has the characteristics of air gap adjusting function, energy saving, comprehensive test on electromagnetic force and work condition, capability of test on high-speed work condition, small size, less space occupation, suitability for indoor use and the like.
