Convenient-to-mount electrical wiring box
ActiveCN109638747AEasy to adjustPlay a role in separatingElectrical apparatusEngineeringElectrical wiring
The invention provides a convenient-to-mount electrical wiring box. The convenient-to-mount electrical wiring box comprises a rectangular box, a wiring protective cover structure, an adjustable lead fixing frame structure, a lead classification marking frame structure, an adjustable mounting frame structure, a lower side protective cover, upper side protective cover, a lower side fixed pipe, a fixed inserted link, a limit ring, a pull ring, an anti-slip sleeve, a sealing pad and an upper side fixed pipe, wherein the wiring protective cover structure is mounted on the upper and lower sides of the rectangular box; and the adjustable lead fixing frame structure is mounted on the upper and lower sides of the inner wall of the rectangular box. A fixing screw is in threaded connection with the middle and lower parts of a rectangular fixing frame through a sliding groove, which is beneficial to loosening the fixing screw and sliding the rectangular fixing frame on the upper side of a transverse mounting plate when in use, so that the position of a clamping line can be adjusted conveniently according to the need of use. A longitudinal division plate is glued to the front middle position ofa dredging plate in turn from left to right, which is beneficial to dredging and separating leads.

Micro-nano drag reduction structure for high-altitude and high-speed environment
PendingCN112550679AReduce viscous dragReduce frictional resistanceDrag reductionAir-flow influencersPhysicsFlight vehicle
The invention provides a micro-nano drag reduction structure for a high-altitude and high-speed environment, which comprises a groove formed in the outer surface of an aircraft, the groove is strip-shaped, the cross section of the groove is an isosceles triangle, the vertex angle of the cross section of the groove is positioned at the bottom of the groove, and the length of the bottom edge of thecross section of the groove is between 150nm and 200nm. The grooves and high-speed airflow form a certain angle, a plurality of grooves are formed in the outer surface of the aircraft in the directionperpendicular to the length direction of the grooves at equal intervals, a partition strip is formed between any two adjacent grooves, the length direction of each partition strip is parallel to thelength direction of the corresponding groove, and the cross section of each partition strip is in an isosceles triangle shape. The vertex angle of the cross section of the dividing strip is located atthe top end of the dividing strip. The viscous resistance near the boundary layer of the near-wall surface can be reduced, the frictional resistance of high-speed gas to the aircraft can be reduced,the structure is simple, the work is reliable, and the drag reduction effect is good.

A kind of preparation method of ultrahigh specific surface area graphene airgel
The invention discloses a preparation method of graphene aerogel with an ultrahigh specific surface area, and aims to enlarge the specific surface area of graphene aerogel without affecting the chemical structure of graphene. The preparation method comprises the following steps: taking graphite powder and siloxane as the main raw materials, preparing oxidized graphene, preparing a dispersion liquid of oxidized graphene, preparing silicon oxide hybridized graphene gel, drying the gel, and finally carrying out high-temperature decomposition to obtain the graphene aerogel with an ultrahigh specific surface area. The raw materials are mixed in liquid, after reactions, silicon oxide nano particles with an extremely small particle size can be evenly dispersed, thus the graphene is dispersed, and the agglomeration is prohibited. Furthermore, high-temperature decomposition is performed to remove the silicon oxide, at the same time the high-temperature decomposition has a certain activating effect, thus the prepared graphene aerogel has an ultrahigh specific surface area, which can reach 2491 m<2> / g, and at the same time the chemical structure is barely influenced.
