Problems solved by technology

[0003] The protective cover of the vehicle-mounted catenary operation status monitoring device needs to be sealed. The sealing device of the existing protective cover is usually pressed on the base with a rubber gasket. As the use time increases, the gasket gradually ages and the permanent deformation of the gasket increases. Large, the pre-tightening force of the screw gradually decreases, which may easily cause the screw to loosen

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] figure 1 A boot seal according to one embodiment of the invention is schematically shown. According to the protective cover sealing device of the present invention, a sealing groove and a sealing member are provided, which can not only prevent deformation and fall off, but also play a role of positioning and facilitate installation.

[0030] Such as figure 1 and figure 2 As shown, the protective cover sealing device described in this embodiment includes a base 1 . The base 1 is a flat plate structure, preferably a circular plate structure, and may also be rectangular or other shapes, determined according to the shape and size of the catenary operating state detection device. The protective cover of the catenary detection device in this embodiment further includes an outer cover 2 , the edge of the outer cover 2 matches the shape of the edge of the base 1 . Wher...

Abstract

The invention relates to a protective cover sealing device, in particular to a sealing device for a protective cover of a vehicle-mounted contact network operating state monitoring device. The sealingdevice comprises a base and an outer cover, wherein the base is of a flat plate type structure, the outer cover is fixed on the base, the edge of the outer cover is provided with a connecting edge which is parallel to the base, the connecting edge is fixedly connected to the base, a first sealing groove is formed in the position, in contact with the connecting edge, of the base, and a first sealing piece is arranged in the first sealing groove. According to the sealing device, the sealing piece is installed in the sealing groove of the base, the sealing piece does not move accordingly in a moving process of the outer cover, and installation is convenient.

Description

technical field [0001] The invention relates to a sealing device for a protective cover, in particular to a sealing device for a protective cover of a vehicle-mounted catenary operating state monitoring device. Background technique [0002] The protective cover of the vehicle-mounted catenary operating state detection device is equipped with cameras, fill lights, laser sensors and other components, and is installed on the roof of motor cars, locomotives, urban rail transit vehicles, etc. All-weather testing of the running status requires a higher level of protection. [0003] The protective cover of the vehicle-mounted catenary operation status monitoring device needs to be sealed. The sealing device of the existing protective cover is usually pressed on the base with a rubber gasket. As the use time increases, the gasket gradually ages and the permanent deformation of the gasket increases. If the screw is too large, the pre-tightening force of the screw will gradually decr...
