The invention discloses a waterproof heat insulation cover for a point switch. The waterproof heat insulation cover comprises a cover body with a concave cavity, and a vacuum heat insulation mechanismis arranged at the top of the inner side of the concave cavity of the cover body. The vacuum heat insulation mechanism comprises a heat insulation plate connected with the periphery of the inner sideof the cover body in a sealed mode, a sealing cavity is formed between the heat insulation plate and the top of the inner side of the cover body, and a vacuumizing miniature ball valve is arranged onthe heat insulation plate and used for vacuumizing and sealing the sealing cavity. The sealing cavity is filled with a nano aerogel thermal insulation material. A connecting ring plate is fixedly welded to the edge of the opening of the cover body, a sealing groove is formed in the bottom face of the connecting ring plate, and a T-shaped sealing strip is embedded in the sealing groove. One side edge of the cover body is rotatably connected with a switch machine shell through a hinge, and the hinge is of a U-shaped hinge structure with a limiting mechanism. The cover body is provided with thevacuum heat insulation mechanism and the nano aerogel, so that the heat insulation capacity of the cover body can be greatly improved, the day and night temperature difference in the point switch is reduced, and stable operation of the point switch is facilitated. The waterproof performance is greatly improved, the cover body can be opened and closed more stably and accurately, and use is convenient.

    本发明公开了一种转辙机用防水隔热盖,包括具有凹腔的盖体,盖体凹腔的内侧顶部设有真空隔热机构。真空隔热机构包括与盖体内侧周边密封连接的隔热板,隔热板与盖体内侧顶部之间形成密封腔,隔热板上设抽真空微型球阀,用于实现密封腔抽真空及其密闭。密封腔中填充纳米气凝胶保温材质。盖体开口边缘固定焊接连接环板,连接环板底面上开设密封槽,密封槽中嵌设有凸字形密封条。盖体一侧边通过铰链与转辙机壳体可转动连接,铰链采用带限位机构的U型铰链结构。本发明通过在盖体上设置真空隔热机构并设置纳米气凝胶,能大幅提高盖体隔热能力,降低机内昼夜温差,利于转辙机平稳运行。还大大提高了防水性能,并使盖体启闭更平稳、准确,使用方便。
