The extracting tank comprises a tank body, a stirring mechanism, and a plurality of side-placed rinsing mechanisms, wherein a heating spacer bush is arranged at the outer wall of the tank body, a heating medium leading-in connector and a heating medium leading-out connector are arranged on the heating spacer bush, and the top of the tank body is provided with a feeding port and a demister connector; a stirring motor coordinates with a stirring decelerator, a stirring shaft is located in a tank body cavity, a stirring shaft support is fixed on the cavity wall of the tank body cavity, and the shaft body of the stirring shaft is provided with a stirring blade; an acting cylinder is arranged on the tank body, one side of a slag discharging gate is hinged to the tank body, the other side of the slag discharging gate is connected with the acting cylinder, and the center is provided with an extracting solution leading-out port; the side-placed rinsing mechanisms are arranged on the side wall of the tank body and stretch into the tank body cavity. The extracting tank is characterized in that the stirring blade is composed of a helical band supporting frame and a helical band, the helical band supporting frame is fixed to the stirring shaft, and the helical band is fixed on the helical band supporting frame and maintains certain distance from the stirring shaft and the cavity wall of the tank body cavity. In this way, requirements of interchanging between a cold zone and a hot zone are satisfied, and an effect of uniform temperature of a material is guaranteed; meanwhile, influence of moment of force on the stirring shaft and stress degree of the stirring shaft are lowered, and thus appearance of deformation can be avoided; in addition, the rinsing effect of the extracting tank is good.

The invention belongs to the design technology of aircraft movable surfaces, in particular to a leading edge slat with adjustable attitude. The attitude-adjustable leading edge slat includes a reinforcing rib (1), a slide rail (2), and a double eccentric bushing (3), wherein the reinforcing rib (1) passes through two holes connecting the lug and the slide rail (2). For fixed connection, two sets of double eccentric bushings (3) are respectively arranged in the outer connecting holes between the reinforcing rib (1) and the slide rail (2), and fixed by stud bolts (4). The leading edge slat with adjustable attitude of the present invention can adjust the attitude after the slat is installed, so as to ensure the aerodynamic gap requirements between the movable surface and the fixed surface, meet the interchangeability requirements, and ensure the zero position of the operating system. In addition, the attitude-adjustable leading-edge slat has a simple structure and is easy to adjust, which greatly reduces the difficulty of clearance control.

The invention discloses a 1 / 2 drawer unit of a drawer type power distribution cabinet. The 1 / 2 drawer unit comprises a drawer body and a plurality of primary movable inserts and secondary movable inserts. The drawer body comprises a drawer panel and drawer lateral boards on two sides. Every primary movable insert comprises an inserting type switch body, a switch base and a switch base installation frame, wherein the switch base installation base is arranged in the middle of a power distribution cabinet framework, and the bottom of the drawer body is supported on a separation board of a drawer layer through a plurality of guide rails. The secondary movable inserts are nine-needle connectors arranged in the inserting type switch bodies, primary plugs on the inserting type switch bodies are respectively inserted into corresponding sockets on the switch base, and inserting needles of the nine-needle connectors are inserted into corresponding jacks on the switch base. The maximum current capacity of the 1 / 2 drawer unit is improved to 250A, so that requirements for exchanging of the drawer type power distribution cabinet are met. The primary movable inserts and the secondary movable inserts of the inserting type switch body are reliable and accurate in contact, and the radiating effect is good.

The invention provides a movable battery holder which comprises a base and a metal sheet partially welded on the base, wherein the base comprises a working platform used for accommodating a battery, and a baffle plate arranged aslant above the working platform and connected with the working platform; and the metal sheet also comprises a first free end extending above the working platform and a second free end extending below the baffle plate. The movable battery holder can be independently produced together with a PCB (Printed Circuit Board), is assembled and combined with the PCB during use, can be independently replaced during replacement, meets the interchange requirement, and is saving in cost.

The invention provides an interchangeability design method for a domestic satellite-mounted travelling-wave tube amplifier and an imported satellite-mounted travelling-wave tube amplifier. The method comprises a step of mechanical interface interchangeability design, a step of input excitation interchangeability design and a step of usage pattern interchangeability design, wherein the step of mechanical interface interchangeability design comprises enabling installing interfaces of two travelling-wave tubes to be consistent with each other, be consistent with heat pipe layout interfaces positioned on a satellite structure boards and be consistent with antenna waveguide output interfaces; the step of input excitation interchangeability design comprises adjusting intensity of input excitation signals by externally connecting a fixed attenuator so as to meet the requirements of excitation of different saturation points of the two travelling-wave tubes; and the step of usage pattern interchangeability design comprises adding movement options of instructions such as starting / shutdown, feeding low pressure and discharging low pressure in operations schedule design so as to meet the requirements of two products for different usage patterns. According to the interchangeability design method, interchanging usage of the domestic travelling-wave tube amplifiers and the imported travelling-wave tube amplifier can be achieved, and flexibility in product matching in a subsystem scheme is guaranteed. The interchangeability design method is already applied in some satellite data transmitting subsystem.
