[0045] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0046] Example:

[0047] like Figures 1-5 As shown, a power distribution room instrument information acquisition robot includes:

[0048] Mobile robot 1, with a connecting mounting block on its top;

[0049] The fixed connecting frame 2 is connected to the connecting mounting block on the top of the mobile robot 1 by bolts, and a wireless controller is provided on its inner side;

[0050] The fixed connecting wheel 3 is bolted to the bottom end of the fixed connecting frame 2;

[0051] The top plate 4 is connected and installed, and is fixedly welded to the top of the fixed connecting frame 2;

[0052] The fixed guide base 5 is located below the mobile robot 1 and the fixed connecting wheels 3, and is connected to the ground by expansion bolts;

[0053] The lifting information collection mechanism 6 is bolted to the top of the connecting and mounting top plate 4;

[0054] The drive mechanism 7 is bolted to the top of the mounting plate 4;

[0055] The fixing and fastening mechanism 8 is fixedly installed on the top of the connecting and mounting top plate 4;

[0056] The storage battery 9 is movably placed on top of the connecting mounting plate 4 and is located inside the fixing and fastening mechanism 8.

[0057] Junction box 10 is fixedly mounted on top of battery 9;

[0058] The connection positioning component 11 is bolted to the top of the connection mounting plate 4.

[0059] The working principle of the above technical solution is as follows:

[0060] During use, the mobile robot 1 is remotely started, enabling it to move on top of the fixed guide frame 5. Then, the drive mechanism 7 is driven, which in turn drives the lifting information acquisition mechanism 6, allowing the lifting information acquisition mechanism 6 to perform lifting and lowering operations. This allows for stable acquisition of instrument information from the power distribution room, eliminating the need for manual on-site data collection. The structure is simple and the operation is convenient.

[0061] In another embodiment, such as Figure 2 As shown, the fixed guide base 5 includes a fixed support plate 51. The top of the fixed support plate 51 is symmetrically provided with fixed guide limiting side blocks 52. Both sides of the fixed support plate 51 are provided with connecting side blocks 54. The interior of the connecting side blocks 54 is provided with fixed installation through holes 55 at equal intervals. The end of the fixed support plate 51 is provided with a fixed inclined surface 53.

[0062] The fixed connecting wheel 3 can move between the fixed guide limit block 52 and the top of the fixed tray 51 for guidance and restriction. At the same time, the mobile robot 1 can move stably on the surface of the fixed tray 51, making it easy to operate.

[0063] In another embodiment, such as Figure 3As shown, the lifting information acquisition mechanism 6 includes a connecting mounting leg 61. One end of the connecting mounting leg 61 is fixedly connected to a fixed guide rod 62. The inner side of the fixed guide rod 62 is fixedly connected to a first fixed frame 63. The inner side of the first fixed frame 63 is movably connected to a movable threaded rod 64. The bottom end of the movable threaded rod 64 is fixedly connected to a driven bevel gear 65. A fixed limiting ring 66 is fixedly sleeved on the outer side of the movable threaded rod 64. The top end of the inner side of the fixed guide rod 62 is fixedly connected to a second fixed frame 67. The outer side of the movable threaded rod 64 and the inner side of the fixed guide rod 62 are movably connected to a lifting mounting block 68. The lifting mounting block 68 and the movable threaded rod 64 are connected by threads. Information acquisition components 69 are provided on both the front and rear surfaces of the lifting mounting block 68. The driven bevel gear 65 is located below the first fixed frame 63, and the fixed limiting ring 66 is located above the first fixed frame 63.

[0064] When the drive mechanism 7 drives the driven bevel gear 65, the driven bevel gear 65 can drive the fixed limit ring 66 and the movable threaded rod 64 to rotate, so that the lifting mounting block 68 can move on the outer side of the movable threaded rod 64 and the inner side of the fixed guide rod 62, thereby driving the information acquisition component 69 to move, so that the information acquisition component 69 can stably collect and process the instrument information in the power distribution room, and is easy to operate.

[0065] In another embodiment, such as Figure 3 As shown, the information acquisition component 69 includes a fixed limiting frame 691, a movable mounting plate 692 is movably inserted into the inner side of the fixed limiting frame 691, a fixed connecting arm 693 is fixedly connected to the lower part of the side of the movable mounting plate 692 away from the lifting mounting block 68, a fixed connecting plate 694 is fixedly connected to the end of the fixed connecting arm 693 away from the movable mounting plate 692, and an information acquisition camera 695 is fixedly connected to the top of the fixed connecting plate 694.

[0066] The movable mounting plate 692 is easily inserted into the inside of the fixed limiting frame 691 to install the fixed connecting arm 693, the fixed connecting plate 694 and the information acquisition camera 695, so that the information acquisition camera 695 can stably collect the instrument information of the power distribution room and is easy to operate.

[0067] In another embodiment, such as Figure 4 As shown, the drive mechanism 7 includes a drive motor 71, a fixed mounting bracket 72 is fixedly sleeved on the outer surface of the drive motor 71, the end of the fixed mounting bracket 72 is connected to the connecting mounting top plate 4 by bolts, the output end of the drive motor 71 is connected to a reducer 73, and the output end of the reducer 73 is connected to a drive bevel gear 74.

[0068] This facilitates the drive motor 71 to drive the reducer 73, enabling the output of the reducer 73 to drive the active bevel gear 74, which in turn drives the driven bevel gear 65 when rotating, making operation convenient.

[0069] In another embodiment, such as Figure 4 As shown, the connection and positioning assembly 11 includes a connection and mounting end block 111. One end of the connection and mounting end block 111 is fixedly connected to the positioning seat body 112. The connection and mounting end block 111 is connected to the connection and mounting top plate 4 by bolts.

[0070] The positioning seat body 112 can provide positioning support for the output end of the reducer 73, so that the output end of the reducer 73 can be used stably and is easy to operate.

[0071] In another embodiment, such as Figure 5 As shown, the fixing and fastening mechanism 8 includes a connecting mounting frame 81. A bidirectional threaded rod 82 is movably connected inside the connecting mounting frame 81. Both ends of the bidirectional threaded rod 82 are fixedly connected to connecting mounting discs 83. A connecting mounting rod 84 is fixedly connected to the side of one of the connecting mounting discs 83 away from the bidirectional threaded rod 82. A connecting rotating disc 85 is fixedly connected to the end of the connecting mounting rod 84 away from the connecting mounting disc 83. Movable mounting blocks 86 are symmetrically provided on the outer surface of the bidirectional threaded rod 82 via threads. A first connecting seat 87 is fixedly connected to one side of the movable mounting block 86. A movable deflection arm 88 is movably connected to the inner side of the first connecting seat 87 via a connecting shaft. A second connecting seat 89 is movably connected to the other end of the movable deflection arm 88 via a connecting shaft. A connecting pressing push plate 810 is fixedly connected to the side of the second connecting seat 89 away from the movable deflection arm 88.

[0072] This facilitates the rotation of the connecting rotating disk 85, causing the connecting mounting rod 84, connecting mounting plate 83, and bidirectional threaded rod 82 to move. This allows the movable mounting block 86 to move on the outer side of the surface of the bidirectional threaded rod 82, moving the first connecting seat 87 and enabling the movable deflection arm 88 to deflect. Simultaneously, it pushes the second connecting seat 89 and the connecting pressing push plate 810, cooperating with the connecting mounting frame 81 to clamp and fix the battery 9, ensuring that the battery 9 is stably positioned inside the connecting mounting frame 81, making operation convenient.

[0073] The working principle of this utility model is as follows: During use, the operator can remotely control the entire system, enabling the mobile robot 1 to move on top of the fixed pallet 51. Simultaneously, the fixed connecting wheel 3 can move between the top of the fixed pallet 51 and the fixed guide limit block 52, allowing the entire system to move stably next to the instruments in the power distribution room. Then, the drive motor 71 drives the reducer 73, causing the output of the reducer 73 to drive the active bevel gear 74. When the active bevel gear 74 rotates, it drives the driven bevel gear 65, which in turn drives the movable threaded rod. Rotation of the driven bevel gear 64 and driven bevel gear 65 causes the lifting mounting block 68 to move on the outside of the movable threaded rod 64 and the inside of the fixed guide rod 62, thereby moving the fixed limiting frame 691, movable mounting plate 692, fixed connecting arm 693, fixed connecting plate 694, and information acquisition camera 695. This allows the information acquisition camera 695 to collect and process instrument information from the power distribution room. When disassembly and maintenance of the information acquisition camera 695 are required, the fixed limiting frame 691, movable mounting plate 692, fixed connecting arm 693, fixed connecting plate 694, and information acquisition camera 695 are moved directly, causing the movable mounting plate 691, driven bevel gear 692, fixed connecting arm 693, fixed connecting plate 694, and information acquisition camera 695 to move. 2. The battery 9 is disassembled from the inside of the fixed limiting frame 691 for quick removal. When the battery 9 needs to be removed for replacement and charging, the connecting rotating disk 85 is rotated, causing the connecting mounting rod 84, connecting mounting plate 83, and bidirectional threaded rod 82 to move. This allows the movable mounting block 86 to move on the outer surface of the bidirectional threaded rod 82, moving the first connecting seat 87 and causing the movable deflection arm 88 to deflect. Simultaneously, the second connecting seat 89 and the connecting pressing push plate 810 are pulled, causing the connecting pressing push plate 810 to no longer engage with the connecting mounting frame 81, thus clamping and fixing the battery 9. At this point, the battery 9 can be removed. Remove and replace the battery 9. Place the replaced battery 9 inside the connecting mounting frame 81. Then rotate the connecting rotating disk 85, which drives the connecting mounting rod 84, the connecting mounting plate 83, and the bidirectional threaded rod 82 to move. This allows the movable mounting block 86 to move on the outer side of the surface of the bidirectional threaded rod 82, which in turn drives the first connecting seat 87 to move. This allows the movable deflection arm 88 to deflect, while simultaneously pushing the second connecting seat 89 and the connecting pressing push plate 810. These components cooperate with the connecting mounting frame 81 to clamp and fix the battery 9, ensuring that the battery 9 is stably positioned inside the connecting mounting frame 81. The overall structure is simple and the operation is convenient and quick.

[0074] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
