In addition, the batteries of the UPS devices can be charged by the bus bars 201.

Based on this, as shown in fig. 9, when the live wire connecting assembly M and the neutral wire connecting assembly N are assembled, the free end of the second neutral wire rod 202d can be inserted into the insertion hole K of the connecting buckle 202e on the first live wire rod 202a along the Y-axis negative direction, and then the free end of the first live wire rod 202a can slide into and be inserted into the insertion hole K of the connecting buckle 202e on the second neutral wire rod 202 d; meanwhile, the free end of the second live wire rod 202b can also be inserted into the insertion opening K of the connecting buckle 202e on the first zero wire rod 202c, and the free end of the first zero wire rod 202c can slide into the Y-axis negative direction and be clamped into the insertion opening K of the connecting buckle 202e on the second live wire rod 202 b.

Or, as shown in fig. 10, in another assembly manner, the free end of the first live wire rod 202a may be inserted into the insertion hole K of the connecting buckle 202e on the second live wire rod 202d along the negative X-axis direction, so that the free end of the second live wire rod 202d can slide into and be clamped into the insertion hole K of the connecting buckle 202e on the first live wire rod 202 a; meanwhile, the free end of the first zero line rod 202c can also be synchronously inserted into the insertion opening K of the connecting buckle 202e on the second live line rod 202b, and the free end of the second live line rod 202b can slide in the negative direction of the X axis and be clamped into the insertion opening K of the connecting buckle 202e on the first zero line rod 202 c.

Further, as shown in fig. 11 and 12, the connecting block 202e-1 is sleeved on the periphery of the free end of the conducting rod and is pressed and fixed by a lateral fastening bolt 202 f. The connecting block 202e-1 is provided with a through hole 202e-11 matched with the cross section profile of the conducting rod and a screw hole 202e-12 corresponding to the fastening bolt 202 f; the through hole 202e-11 is through along the length direction of the pull rod 202e-2, and the connecting buckle 202e can slide into the free end of the conducting rod through the through hole 202 e-11; the screw hole 202e-12 extends perpendicularly to the through hole 202e-11 and is communicated with the through hole, and the fastening bolt 202f can be screwed into the screw hole 202e-12 from the side direction and pressed on the outer side wall of the free end of the conductive rod, so that the connecting buckle 202e is fixed on the free end.

The conducting rod is further provided with a limiting block X which is positioned at the inner end of the connecting block 202e-1, the limiting block X is formed by protruding from the outer side surface of the conducting rod and used for calibrating the sliding position of the connecting buckle 202e on the free end of the conducting rod so as to determine the fixed position of the connecting buckle (when the connecting buckle 202e slides on the conducting rod to be in contact with the limiting block X, the connecting buckle can be fixed through the fastening bolt 202 f).

Further, as shown in FIG. 12, the vertical side edge of the connecting piece 202e-1 corresponding to the end of the hook body 202e-3 in the direction is processed to be a chamfer 202 e-13. When two adjacent conductive rods are mutually meshed and fixed through the respective connecting buckles 202e, the outer end face of the connecting block 202e-1 of any connecting buckle 202e can be attached to the side edge of the pull rod 202e-2 of the other connecting buckle 202e, and the chamfers 202e-13 of the two connecting buckles 202e are attached to each other, so that the two connecting buckles 202e are tightly matched after being connected.

Furthermore, an installation plate 104 is attached and fixed on the inner side wall of the underground pipe gallery 100, a plurality of overhanging and overhanging joint rods 105 are arranged and fixed on the installation plate 104, and the installation plate 104 and the joint rods 105 can be made of insulating materials or coated with insulating materials on the outer layer. Each conductive bar 201 is fixed to the mounting plate 104 by a joint bar 105. Specifically, one side of the conductive bar 201 opposite to the mounting plate 104 is fixedly connected to the connecting bar 105, and the fixing manner may be conventional clamping, integral injection molding, or transverse bolt insertion fixing, which is not described herein again.

As can be seen from the above, the intersections include two types, the crossroad 102 and the t-intersection 103. It should be noted that: as shown in fig. 1 and 2, the branch and the main path are relative, and the straight-line pipeline 101 originally used as the main path may be vertically connected to the outer sidewall of the other straight-line pipeline 101, and becomes a "branch" of the other main path. The invention sets the following steps: if a linear duct 101 is not vertically connected to the outer side wall of any other linear duct 101, the linear duct 101 is an "absolute main path".

The invention can connect the conductive strips 201 in each linear pipeline 101 at each intersection through the wiring frame 202 arranged at the top of each intersection. Therefore, the present invention only needs to select one linear pipeline 101 as an "absolute main path" to configure a power supply (such as a generator or an external power transmission line, commercial power) for itself, so as to form an initial power main path, and the remaining absolute main paths may intersect with each other to form an intersection 102, and are directly or indirectly connected to the initial power main path, so as to obtain the power of the initial power main path in a direct or indirect manner. In addition, all the linear pipelines 101 which can be used as branches can be connected in parallel to any absolute main path through the wiring frame 202, and can also be connected in parallel to other branches through the wiring frame 202 to obtain electric energy, so that the electric energy of one power supply source can be shared.

In summary, the wire frame 202 of the present invention not only solves the "wiring problem of the conductive bars 201 in different straight line pipe sections 101a at the intersections", but also because the wire frame 202 is located at the top of the intersection, the wiring path of the overhead line system 200 is "raised" at each intersection, so that the intelligent cart 300 entering the intersection cannot be difficult to turn and adjust the position due to the wiring limitation of the overhead line system 200. Of course, the smart cart 300 may be temporarily supplied with power at the intersection via the battery of the UPS device.

It is important to note that the construction and arrangement of the present application as shown in the various exemplary embodiments is illustrative only.
