DETAILED DESCRIPTION

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, the automatic sealing device for the rigid contact wire 9 in the subway track area includes a partition door 1, a contact wire 9, and an intermediate sealing component. The intermediate sealing component includes two intermediate sealing blocks 8. The contact wire 9 is disposed between the two intermediate sealing blocks 8. Four movable sealing blocks are disposed around the contact wire 9. The movable sealing blocks are connected to a translation drive device, which drives the movable sealing blocks to move. When sealing the contact wire 9, the four movable sealing blocks apply a top pressure to the intermediate sealing component.

[0019] In this invention, four movable sealing blocks are arranged in four directions around the outer perimeter of the contact wire 9, and are driven to move by a translational drive device. When sealing the contact wire 9, the four movable sealing blocks are driven to move closer to the central sealing component, ensuring all four blocks contact the central sealing component and apply pressure. The central sealing component is located within the space enclosed by the four movable sealing blocks, and the sealing of the contact wire 9 is achieved through the pressure of the blocks. When it is necessary to release the seal on the contact wire 9, the four movable sealing blocks are driven to move away from the central sealing component, disengaging them from the central sealing block. This invention utilizes a translational drive device to control the movement of the movable sealing blocks, enabling automatic sealing and desealing without manual operation, thus improving work efficiency. It allows for rapid response in emergency situations where sealing the contact wire 9 is not possible; simultaneously, it reduces labor costs, improves safety, and minimizes errors that may occur due to manual operation.
