Description

A mobile contact network at civil air defense partition door

Technical Field

The invention belongs to the technical field of urban rail transit, and particularly relates to a movable contact network at a civil air defense partition door.

Background Art

Based on its advantages in energy conservation and environmental protection, convenient travel and promoting the development of urban economic life, urban rail transit has been rapidly developed in more and more cities. Due to the limitations of construction conditions in prosperous areas of the city, most of the urban areas adopt the tunnel mode and set up civil defense units. Interval civil defense partition doors are used between civil defense units for combat separation and protection.

There are no clear design methods and general requirements for contact networks at civil air defense partition doors abroad. Some domestic projects adopt a rigid suspension small anchor section design or a disconnectable device. However, the small anchor section design has the disadvantage of long disassembly and recovery time. When the civil air defense partition door also serves as a flood prevention door, it is difficult to meet the time requirements for quickly disconnecting and closing the flood prevention door. The patent with application number 201821099858.8 discloses a rigid contact network automatic disconnection and recovery device, which consists of three parts: a sliding bus joint, an intermediate section movable bus, and an articulated bus joint. The sliding bus joint and the articulated bus are respectively fixed to the fixed ends of the bus on both sides of the opening and closing track of the flood prevention door or partition door, and one end of the intermediate movable bus is fixed to the articulated bus joint through a hinge shaft. Due to the concentrated mass, this disconnectable device scheme has a certain impact on the current receiving quality of the bow net.

Working principle: A contact network mobile anchor section with a pull-out value is set at the civil air defense partition door, which is connected with the adjacent anchor section through the anchor section joint, and an electrical connection is set at the same time.

The electrical connection box, the electrical connection joints of the busbar terminal and the disconnectable electrical connection mechanism realize the electrical connection between the mobile anchor section and the adjacent anchor section, and the current is supplied to the train pantograph through the contact wire clamped by the busbar, maintaining the continuity of the train current in the power supply arm. In the daily state, the mobile anchor section and the slide rail both use three suspension fixing points. The fixed support suspension point is fixed to the top of the tunnel by anchor bolts. The mobile anchor section is firmly fixed, ensuring the stability of daily current supply to the train pantograph.

In case of emergency, the mobile anchor section will be moved out of the closing range of the civil air defense partition door through the drive of the horizontal transmission mechanism and the power mechanism after the contact network is powered off.

The mobile anchor section 7 is suspended on a slip-off clamp 13 and two sliding mechanisms 11, wherein the slip-off clamp 13 is connected to an insulator 17, and the insulator 17 is connected to a fixed support suspension point A1. The upper end of the sliding mechanism 11 is connected to an I-shaped slide rail 10, wherein the slide rail 10 is suspended on a fixed support suspension point C3 and two fixed support suspension points B2, wherein the fixed support suspension point A1, the fixed support suspension point B2 and the fixed support suspension point C3 are fixed on the top of the tunnel. A horizontal transmission mechanism 12 is provided next to the movable anchor section 7, and the horizontal transmission mechanism 12 includes a chain 20 and a sprocket 21. The chain 20 is wound around the sprocket 21, and two upper and lower auxiliary sprockets are provided in the middle of the chain. The connecting plate 19 is fixed on the chain 20 and is fixedly connected to the sliding mechanism 11 far away from the civil defense partition door. One of the sprockets 21 is connected to the power mechanism 4.

The bus terminal 6 is provided with an electrical connection joint 8, and the electrical connection joint 8 is connected to the electrical connection box 5, and the electrical connection box 5 is connected to a disconnectable electrical connection mechanism 9, and the disconnectable electrical connection mechanism 9 includes a fixed part and a movable part, and the fixed part is fixedly connected to the slide rail 10, and the movable part is fixedly connected to the movable anchor section 7, and the fixed part is plugged with the movable part, and the fixed part includes an upper fixed frame, an insulator 17 and an electrical connection joint 8, and the insulator 17 is located between the upper fixed frame and the electrical connection joint 8, and the electrical connection joint 8 is connected to the electrical connection box 5. The sliding mechanism 11 includes a pulley 14, a connecting frame 15, an adjusting screw 16, an insulator 17 and a wire clamp 18, and the pulley 14 is located on the connecting frame 15 and connected to the slide rail 10, and the connecting frame 15 is connected to the insulator 17 through the adjusting screw 16, and the insulator 17 is connected to the wire clamp 18, and the movable anchor section 7 is connected to the wire clamp 18.

In case of emergency, the civil air defense door needs to be closed promptly and effectively.

The connecting plate 19 on the chain 20 is rigidly connected to the sliding mechanism 11.
