Output shafts of two servos are respectively connected with different transmission links through rotation rods. One transmission link is hinged with a bent bar fixedly connected to a set of flow deflectors. With the structure, flow deflector angle deflection can be driven. With the flow deflectors and the transmission mechanism provided by the invention, air flow direction can be changed, and air flow volume can be controlled. The structure is simple, safe, and reliable. With the flow deflectors and the transmission mechanism, aircraft structural requirements can be satisfied, good aerodynamic efficiency is provided, and multi-dimensional deflection effect is realized.

The invention discloses an air purification intelligent disinfection device, which comprises a fuselage. A disinfection chamber with an upward opening is arranged in the top wall of the fuselage. A water outlet bump is fixedly arranged on the left wall of the disinfection chamber. The wall is fixed with a heater; the invention can directly use sunlight to disinfect the air. The invention drives the screw to rise by turning the nut, thereby realizing the angle change in the vertical direction of the convex lens, and driving the gear ring to rotate through the gear to drive the convex lens to rotate. , realize the angle change of the horizontal direction of the convex lens, through two changes to achieve the vertical sun rays of the convex lens, can gather the most sunlight into the disinfection room, use the high temperature of the water vapor and the ultraviolet light in the sunlight to achieve the disinfection effect, and can save part of the electric energy At the same time, the purified air is humidified and then discharged. The water mist can humidify the air and reduce the temperature of the air passing through the disinfection room.

The invention discloses a power distribution cabinet with good airtightness, which relates to the technical field of power distribution cabinets and comprises a cabinet body and a cabinet door. One end of the cabinet door is rotatably connected to the outer wall of the cabinet body. There is a heat dissipation window, the top of the cabinet door is provided with a sealing device, and the sealing device is arranged symmetrically at the upper and lower ends of the cabinet door, the inner side wall of the cabinet door is fixedly installed with magnetic suction strips, and the bottom of the cabinet body is provided with A connection block, the two ends of the connection block are embedded and connected with the inner wall of the cabinet body, and the inner wall of the connection block is welded with elastic parts. The present invention reduces the gap between the cabinet door and the cabinet body through the cooperation of the sealing device and the cabinet door, and solves the problem that rainwater easily enters the inside of the cabinet body in rainy days and causes potential safety hazards. The cooperation of the water pipe two can flow the rainwater remaining on the cabinet door into the inside of the water pipe two, which facilitates the discharge of the rainwater and reduces the possibility of the rainwater entering the inside of the cabinet.

The invention discloses a substation automatic control lightning protection system, which comprises a box body, the left and right sides of the lower end of the box body are fixedly connected with pillars, the lower end of the box body is provided with a push-up mechanism, and the push-up mechanism The lower end of the shock absorbing mechanism is provided with a shock absorbing mechanism, and the lower end of the shock absorbing mechanism is fixedly connected with an organic case.
