The invention provides a method for the desorption of volatile component in polymer and a device thereof; the device comprises a shell and a rotor which is filled with ring-shaped filler; a polymer feeding duct enters the filler from a material inlet of the shell, one end of a pipeline is provided with a material distributor which extends into a hollow cavity of the filler, and the distributor isprovided with a plurality of outlets that are corresponding to a liquid receiving ring arranged at the inner side of the cavity of the filler along the direction of vertical height; the filler is concentric ring-shaped multilayer assembly sizing filler. Liquid polymer is transported into the hollow cavity of the filler to be evenly distributed in the hollow cavity of the filler in a layering way along the axial direction, the rotating speed of the rotor is adjusted to lead the supergravity level of the rotor to reach 30-1000g, and the liquid polymer flows through the filler from the cavity towards outside according to the customizing path of the sizing filler. In the supergravity environment, the invention doses not need to desorb gas by enforcing polymer fluid to flow through the filler according to the changing path of the sizing filler, strengthening the interface to update and producing local perturbation, thus simplifying the process and having high devolatilization rate.

A locking and recocking assembly with swivel breech-lock and rotating locking head particularly designed for inertially-actuated weapons, which combines in a single assembly all the functions for locking, opening, case ejection and recocking with locking return, required for correct operation of the weapon; those functions were, until now assigned to various components variously assembled on the weapon. The locking and recocking assembly with swivel breech-lock and rotating locking head has the entire mass, required for inertial operation, concentrated in the swivel breech-lock, which is accommodated completely within the supporting structure of the weapon, such as the sheath or barrel extension or breech of the weapon. All this leads to better balancing and stability of the weapon, higher reliability in operation, greater constructive simplicity and ease of assembly and disassembly.

The invention relates to a mechanism with a flexible sub switch buffering anti-rebound device on a low-voltage circuit breaker. The low-voltage circuit breaker comprises left and right fixed plates, amain shaft arranged between the two fixed plates and is used for forming a transmission mechanism, and a contact mechanism which is arranged between the fixed plates. The mechanism with a flexible sub switch buffering anti-rebound device comprises a bracket, an oil cup, a cup cap, a piston, crank arms and a roller. The bracket is fixed on the fixed plates, the oil cup is fixed on the bracket andis filled with oil, the piston is arranged in the oil cup, an upper end of the piston is connected to the cup cap, the crank arms are connected to the main shaft, the roller is connected between the two crank arms, and the roller is located directly above the cup cap. When the circuit breaker is switched on, the roller is not in contact with the cup cap, when the circuit breaker is switched off, the main shaft rotates to drive the roller to move to press the cup cap down, the cup cap drives the piston to move downward, and the oil in the oil cup is compressed. When the circuit breaker is quickly switched off and an opening distance is small, the rebound of the circuit breaker in switch-off can be reduced by the mechanism of the invention.

The invention relates to a rapid lifting device of an angle steel straightening roll. The rapid lifting device of the angle steel straightening roll comprises a round outer ring, lifting lugs, V-shaped baffles, vertical plates, pin holes A, pins B, pins A and pin holes; the opened round outer ring is connected with a to-be-lifted angle steel straightening roll in a sleeving manner; and three lifting lugs and four V-shaped baffles are fixed on the outer wall and the inner wall of the round outer ring correspondingly. Two mutually parallel vertical plates are arranged in the opening position ofthe round outer ring, and the two vertical plates extend outwards from the opening of the round outer ring. The pin holes A are formed in the centers of the two vertical plates; and the pins A are inserted into the pin holes A. The rapid lifting device of the angle steel straightening roll is simple to manufacture, adopts few materials, can realize rapid lifting of straightening rolls with different size and different number on an angle steel rolling line, and is simple to adjust and rapid in change. The lifting lugs are uniformly distributed on the round outer ring by 120 degrees; and when the straightening rolls are rapidly lifted, the balance stability is high, and safety and rapidness are realized.

The invention discloses a chassis for a full electric vehicle, and belongs to the technical field of electric vehicle chassis. The chassis comprises a chassis frame for supporting the weight of a vehicle body, and a wheel assembly, a driving mechanism, a steering assembly, a braking assembly and a bumper which are arranged on the chassis frame. The chassis frame comprises a bin-type longitudinal beam arranged on the axis of the chassis. The bin-type longitudinal beam is of a through structure. The front end and the rear end of the bin-type longitudinal beam are provided with a front blocking door and a rear blocking door respectively. A positioning battery case is arranged in the bin-type longitudinal beam through a longitudinal guide mechanism and a positioning mechanism. An emergency braking device of the battery case is formed through a wedge-shaped braking shoe structure at the bottom of the bin-type longitudinal beam. By improving the structure of the bin-type longitudinal beam, the installation and arrangement structure of the battery case and the protection measures of the battery case, the technical requirements for rapid installing and positioning, rapid replacing, ventilating and cooling and overall protecting of the battery case are met.

The invention relates to a wind collecting vertical type wind power generating system which comprises a wind power system, a vertical type speed increaser, a vertical type generator and an excitation grid-connected control system, wherein the wind power system is connected with the speed increaser and the generator by a chain coupling; the generator is controlled by the excitation grid-connected control system; the wind power system is in a box frame structure and comprises a fan blade system and a wind collecting and protecting system; the upper end and the lower end of a box frame are respectively provided with an upper shed top and a lower shed plate; the wind collecting and protecting system comprises a plurality of wind collecting plates which are distributed at four sides of the boxframe and hydraulic drive equipment; the upper shed top, the lower shed plate and the wind collecting plates are connected to form a wind tunnel box type wind collecting body; the generator works in a multi-winding pole-changing control way; and the generator and the speed increaser are installed on the ground. The invention has the advantages of small size, low installation, maintenance and transportation cost, high wind power utilization ratio and wind field land utilization ratio, stable performance, high storm wind resistance and favorable power generating quality and grid-connected performance, can form a high-power wind power generator unit system and is suitable for various weather and geographic environments.

A control method for an electric vehicle supplementary lithium battery pack equalization device, comprising the following steps: when the power battery pack is charging, the ECU records the charging current of the battery pack and the terminal voltages of all single cells within a period of time; when the power battery pack When any one of the single cells is fully charged, the charging stops, and the ECU records the change data of the terminal voltage of all the single cells within a period of time after the charging current is 0; The distance to fully charge the required power data; the ECU reads the stored supplementary power data of all single cells in the power battery pack, and starts the supplementary lithium battery pack balancing device to adjust the power of the single cells that are seriously behind. Carry out supplementary electricity; measure and judge each time the battery pack is charged, perform equalization when discharging, and execute the above steps cyclically. The invention is suitable for the synchronous control of the charging cut-off point of the battery pack, and is efficient and fast, and the system responds quickly.
