The invention discloses an automatic machine for collecting and sorting plastic soft bottles. The device comprises a conveyor for plastic bottles, soft bottles or soft bags, as well as a machine frame, wherein a traction device moving horizontally is arranged above the machine frame; a bottle clamping device connected via a lifting cylinder is arranged on a moving trolley of the traction device; the traction device, the lifting cylinder and the bottle clamping device are connected with an electric control device with electrical automatic control; a product collecting device is arranged below the machine frame beside the conveyor; and the electric control device controls the bottle clamping device to make vertical up-down lifting movement under the drive of the lifting cylinder and to make horizontal translating movement under the drive of the traction device, and controls the bottle clamping device to clamp a product input by the conveyor, to transfer the product to the product collecting device through the lifting cylinder and the traction device and then to unclamp the product. The machine can clamp, lift and translate plastic bottles, soft bottles or soft bags input by the conveyor to a preset distance, drop and put the bottles or bags into the product collecting device.

The intelligent dispatcher for group controlled lifts based on image recognizing technology includes one central dispatching computer for group controlled lifts and with one dispatching control strategy module for the optimized control of the lifts in the building, visual car sensors for acquiring the passenger flow information, and omnibearing visual sensors for acquiring the waiting passenger information, with the visual car sensors and the omnibearing visual sensors being connected to the central dispatching computer. The central computer includes also a lift passenger flow calculating module, and a running mode recognizing module to divide different lift group running modes, except its dispatching control strategy module for selecting dispatching control strategy fitting different running modes. The present invention can detect real-time passenger flow information and has precise group control dispatching.

The invention discloses an intelligent and convenient consignation and payment system, which comprises a terminal device and a server system. The terminal can solve the conflict problem in time and place between couriers and users during collection and delivery processes of expresses, and a built-in 3D (three-dimensional) camera shooting and scanning device can simultaneously automatically record the integrity of every parcel, provide evidences for solving issues involved in object damages and the like and control a cabinet door to open and close through a Bluetooth and short message interaction way, the operation is safe, convenient and fast, and the express delivery efficiency and the user satisfaction degree can be effectively improved. In addition, the terminal can be used for paying water and electricity bills, as well as telephone charge, and charging mobile phones and electric vehicles, thereby being a comprehensive and convenient service terminal.

The invention discloses a commercial liquid crystal display screen based on a metamaterial satellite antenna. The commercial liquid crystal display screen comprises a metamaterial satellite antenna system for receiving satellite signals and the liquid crystal display screen for displaying advertising information. The metamaterial satellite antenna system comprises a tuner, a flat metamaterial arranged vertically and a reflecting plate located at the back of the flat metamaterial, the flat meta material comprises a plurality of layers of metamaterial sheet layers, and each layer of the metamaterial sheet layers comprises a substrate and artificial microstructures distributed on the substrate periodically. According to the commercial liquid crystal display screen, the flat metamaterial satellite antenna is prepared by adopting a metamaterial principle, the flat metamaterial satellite antenna is integrated with an existing commercial liquid crystal display screen well so as to enable the commercial liquid crystal display screen to change display frames in real time according to the satellite signals, and commercial liquid crystal display screen can play the satellite signals. Simultaneously, the commercial liquid crystal display screen based on the metamaterial satellite antenna is simple in preparation process, low in cost, small in volume and convenient to install and maintain.

The invention relates to a low-head shaft-extension tubular pump turbine and blades thereof, and belongs to the technical field of energy power. The low-head shaft-extension tubular pump turbine comprises a pump turbine body, a reversible motor, a flow channel and a flow guide mechanism, the flow channel comprises a water inlet section flow channel, a guide blade section flow channel, a runner chamber and an S-shaped exhaust water pipe flow channel which are sequentially communicated, a runner is in transmission connection with the reversible motor through a spindle, the flow guide mechanism is arranged on the other side of the runner, the runner comprises a runner boss and a runner cone, the blades are circumferentially and uniformly arranged on the runner boss, the middle of each blade is thick while two sides of each blade are thin, each blade is in the shape of a three-dimensional warped surface, and spatial characteristics of each blade are indicated by an upper section, a middle section and a lower section. The operation conditions of power generation by a turbine and water pumping by a pump can be simultaneously met and are opposite in water flow direction, namely, the same runner needs to simultaneously meet the double requirements of water pumping and power generation, the efficiency of the two operation conditions can be simultaneously considered, and the low-head shaft-extension tubular pump turbine is applicable to a low-head pumped storage power station.
