Description

Scheme for wired power transmission to mobile equipment in local area

Technical Field

The invention relates to a tenth scheme for transmitting power to a local area mobile device in a wired mode.

Background

My invention technology, a scheme for wired power transmission to local mobile equipment, can solve a part of problems of wired power transmission to the local mobile equipment. The disadvantages are that: due to the self-weight limitation of the spiral cable, the stretching rate cannot be made large, so that the working area of the mobile equipment in a single local area is greatly limited.

The invention aims to provide a tenth scheme for supplying power to the mobile devices in the local area in a wired mode. So that the mobile device can use the power electricity as the energy source in a larger local area.

Disclosure of Invention

The invention is realized by the following steps: two vertical columns are fixed in the middle of two sides of the working area of the mobile equipment, and two horizontal parallel cables are installed at the upper ends of the two vertical columns. The four corners of each sliding block are respectively provided with a linear bearing which is sleeved on the two cables and can horizontally slide along the cables. One end of a sliding rod is welded with a check ring, the other end of the sliding rod is horizontally hinged with a U-shaped component A, an inner hole of a linear bearing B is sleeved on the sliding rod, and an outer ring of the linear bearing B is horizontally hinged with a U-shaped component B to form a sliding rod assembly which can horizontally slide. U-shaped member A is vertically hinged below the center of the sliding block and can vertically rotate around the sliding block. And a pair of screw holes are transversely processed below the section of rectangular pipe and are welded below the U-shaped component B. The outer diameter of a connecting pipe main body is slightly smaller than the opposite side of the inner wall of the rectangular pipe, a pair of unthreaded holes slightly larger than the screw holes on the rectangular pipe are transversely processed on the connecting pipe main body, and 2 circles of a plurality of screw holes are uniformly processed on the lower surface of the connecting pipe main body according to the circumference. The upper surface of the connecting pipe is sealed and then is provided with a power socket. A bottom plate is fixed with the mobile device through a plurality of bolts, a circular tube B is welded on the bottom plate, the outer diameter of the circular tube B is slightly smaller than the inner diameter of the connecting tube, and a groove is machined in the outer circle. After the connecting pipe is sleeved outside the round pipe B, a plurality of support head bolts are screwed in from a circle of screw holes below the connecting pipe and inserted into the grooves in the outer circle of the round pipe B to lock the connecting pipe in the vertical direction, but can rotate vertically. The other group of a plurality of support head bolts are screwed into a circle of screw holes on the connecting pipe and fixed with the upper surface of a three-phase conductive slip ring A. The lower surface of the three-phase conductive slip ring A is fixed on the inner wall of the circular tube B. After the rectangular pipe sleeve is sleeved with the connecting pipe, the two knobs are screwed into the screw holes on the two sides of the rectangular pipe respectively and then penetrate through the unthreaded holes in the connecting pipe to connect the sliding rod assembly with the mobile equipment. When the mobile device moves, the sliding rod assembly can be pulled to automatically follow the mobile device to slide or rotate around the upright post. The upper surface of a three-phase conductive slip ring B is fixed with the central inner wall of the sliding block, and the lower surface of the three-phase conductive slip ring B is fixed with the center of the U-shaped component A. The power line is connected to the three-phase conductive slip ring B along the upright post, the middle horizontal part is wound into a spiral shape, and the spiral power line is hung on the cable through a plurality of hanging rings. The power line extending out of the lower part of the three-phase conductive slip ring B is spirally wound outside the sliding rod 8, then passes through the central hole of the U-shaped component B, is connected with a waterproof power socket, and can be plugged and electrified with a power plug fixed on the connecting pipe. An outgoing line on the three-phase conductive slip ring A is connected with a power plug, and an outgoing line on the lower side of the three-phase conductive slip ring A leads to the inside of the mobile equipment. Since the weight of the power cord is primarily borne by the cable and slide bar assembly, the length of the cable and slide bar can be made long enough to be connected, and the slide bar assembly can be rotated vertically about the slide block, the working area of a single area can be larger.

By adopting the technical scheme of the invention, the mobile equipment can use the power electricity as the energy source in a larger local area, and the mobile equipment is particularly suitable for agricultural machinery with a larger work local area.

Fig. 4 is a perspective view of an embodiment of the present invention.

Referring to figures 1, 2, and 3: two upright posts 1 are fixed in the middle of two sides of the working area 21. Two horizontal parallel cables 2 are fixed on the upper ends of the two cables. Four corners of the sliding block 5 are respectively provided with a linear bearing 5-1 which is sleeved on the two cables 2 and can horizontally slide along the cables 2. One end of the sliding rod 8 is welded with a retainer ring 8-1 to prevent the sliding rod 8 from sliding out of the linear bearing B10. The other end is horizontally hinged with the U-shaped component A6. The linear bearing B10 is fitted with its inner bore on the slide bar 8, and the outer race is horizontally hinged to a U-shaped member B (for clarity of their construction, the linear bearing B10 and the power cord 4 are not shown in section in the drawings). They constitute a set of sliding rod components which are vertically hinged with the lower center of the sliding block 5 through a U-shaped component A6 and can vertically rotate around the sliding block 5. A pair of screw holes are transversely processed below the rectangular pipe 9-1 and are welded below the U-shaped component B9. The outer diameter of the main body of the connecting pipe 13 is slightly smaller than the size of the opposite side of the inner wall of the rectangular pipe 9-1, a pair of unthreaded holes slightly larger than the screw holes on the rectangular pipe 9-1 are transversely processed on the main body, and a plurality of screw holes of 2 circles are uniformly processed on the lower surface according to the circumference. The connecting pipe 13 is sealed and then is provided with a power socket 12. The base plate 18 is fixed to the mobile device 20 by four bolts 19. A round tube B17 is welded on the upper surface of the connecting pipe, the outer diameter of the round tube B is slightly smaller than the inner diameter of the connecting pipe 13, and a groove is processed on the outer circle. The connecting pipe 13 is sleeved outside the circular pipe B17, and a plurality of support bolts 16 are screwed in from a screw hole of a circle below the connecting pipe 13 and inserted into a groove on the outer circle of the circular pipe B17 to lock the connecting pipe 13 in the vertical direction but can rotate vertically. And the other group of a plurality of branch head bolts 16 are screwed into a circle of screw holes on the upper surface of the round pipe 13 and are fixed with the upper surface of the three-phase conductive slip ring A15, and the lower surface of the three-phase conductive slip ring A is fixed on the inner wall of the round pipe B17. After the rectangular tube 9-1 is sleeved with the connecting tube 13, the two knobs 14 are respectively screwed into the screw holes on the two sides of the rectangular tube 9-1 and then pass through the unthreaded holes on the connecting tube 13 to connect the sliding rod assembly with the mobile device 20. When the moving device 20 moves, the sliding rod assembly can be dragged to automatically follow the sliding rod assembly or slide or rotate around the sliding block 5. The upper surface of the three-phase conductive slip ring B7 is fixed with the central inner wall of the sliding block 5, and the lower surface of the three-phase conductive slip ring B7 is fixed with the center of the U-shaped component A6. The power line 4 is connected to the three-phase conductive slip ring B7 along the upright post 1, and the middle horizontal part is wound into a spiral shape and hung on the cable 2 through a plurality of hanging rings 3 to extend or contract along with the sliding block 5. The power line 4 extending out of the lower part of the three-phase conductive slip ring B7 is spirally wound outside the sliding rod 8, then passes through the central hole of the U-shaped component B9, is connected with a waterproof power socket 11, and can be plugged and electrified with a power plug 12 fixed on a connecting pipe 13. The upper outlet of the three-phase conductive slip ring A15 is connected with the power plug 12, and the lower outlet leads to the inside of the mobile device 20. With such a structure, the power cord 4 is prevented from being wound and the power transmission is safe and reliable regardless of the rotation and movement of the mobile device 20. Since the weight of the power cord 4 is mainly borne by the cable 2 and the sliding rod assembly, the length of the cable 2 is increased by increasing the distance between the two uprights 1, the sliding rod 8 can also be made long and the sliding rod assembly can be vertically rotated around the sliding block 5, so that the working area of the single area 21 can be larger. The linear bearing B10 may be a rolling bearing or a sliding bearing, which is a common technique. The slide bar 8 is generally formed of a circular tube so that the linear bearing B10 can be a general-purpose product. Of course, other cross-sectional shapes can be used. The structures of the three-phase conductive slip ring a15 and the three-phase conductive slip ring B7 are common technologies, and will not be described in detail here.

In this way, the longitudinal dimension of the whole set of mechanism, i.e. the distance between the two uprights 1, can be very large, and the transverse distance of the two sets of mechanism is only slightly less than twice the length of the sliding rod 8, so that the vertical projections of the working areas of the two sets of mechanism are partially overlapped. The mobile device 20 in the figure is an agricultural machine, and after the work of the working area of a set of components is completed, the device moves to a projection overlapping area, two knobs 14 are screwed out, a rectangular pipe 9-1 is moved upwards to be separated from a connecting pipe 13, and then a waterproof power socket 11 is pulled out from a power plug 12 to push away the original sliding rod component.
