Problems solved by technology
When closing the anti-flooding door, it is necessary to disassemble a section of bus bar at the anti-flooding door from the entire catenary system. However, when the situation is urgent or the water potential is large, personnel cannot enter the tunnel for disassembly, so that the anti-flooding door cannot be removed in time. closed to cause an accident or hazard

Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the following examples are based on the premise of this technical solution, and provide detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.
[0031] like Figure 1-2 As shown, a rigid system detachable bus bar suspension device includes a rigid support mechanism 1 and a bus bar; the bus bar includes at least two bus bar terminals 5 located at both ends and at least two Central busbar 6. In this embodiment, there are two middle bus bars 6, and they are bent end bus bars, that is, in this embodiment, the two middle bus bars adjacent to the bus bar terminals at both ends, and the connection is located at the anti-flooding The two middle bus bars below the door refer to the same two middle bus bars.
[0032] The two middle bus bars 6 adjacent to ...

The invention discloses a detachable busbar suspension device of a rigid system. The detachable busbar suspension device comprises a rigid support mechanism and a busbar, wherein the busbar comprises busbar terminals located at two ends and two middle busbars located between the busbar terminals at two ends; opposite ends of the two middle busbars are electrically connected separately and the other ends are electrically connected with the two busbar terminals separately; each busbar terminal is connected with a rigid support mechanism through a suspension clamp, and one end, connected with the corresponding busbar terminal, of each middle busbar is connected with the rigid support mechanism through the suspension clamp with a rotary structure; and the two middle busbars are connected to the corresponding suspension clamps through detachable and adjustable suspension mechanisms and the suspension clamps are connected to the corresponding rigid support mechanisms. The detachable busbar suspension device is capable of achieving automatically falling off and disconnecting under certain circumstances when a flood gate is closed.
Description
technical field [0001] The invention relates to the field of catenary technology, in particular to a rigid system detachable bus bar suspension device. Background technique [0002] With the rapid development of my country's urban rail transit construction, the form of rigid suspension catenary is widely used. Rigid suspension catenary is a system composed of catenary embedded in head-to-tail busbars. It is an important equipment for the power supply of electrified railway locomotives and rail transit vehicles. Its quality directly affects the operation of locomotives. The anti-flood door is designed when the urban subway tunnel passes under the river. When the rigid suspension catenary encounters special situations of war or serious water leakage, it is necessary to quickly close the anti-flood door of the tunnel to ensure the safety of the tunnel and personnel. When closing the anti-flood door, it is necessary to disassemble a section of bus bar at the anti-flood door fro...
