Specific embodiments

[0019] In order to further understand the invention content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings as follows.

[0020] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] As Figures 1 to 4 shown, a power distribution device for coal mine exploitation provided by an embodiment of the present invention includes a power distribution cabinet 1 and two installation shells 2. The rear side of the power distribution cabinet 1 is fixedly connected to the front side of the installation shell 2. The rear side of the power distribution cabinet 1 is movably connected to an installation plate 3. The installation plate 3 is installed on the installation surface through bolts. The surface of the installation shell 2 is in contact with the surface of the installation plate 3. A control block 4 is movably connected to the inner cavity of the installation shell 2. One side of the control block 4 away from the power distribution cabinet 1 penetrates through the installation shell 2 and extends to the outside of the inner cavity of the installation shell 2. A limiting device 5 is arranged inside the installation shell 2.

[0022] Referring to Figure 4 , the limiting device 5 includes two limiting blocks 501. A stabilizing hole 502 is opened on the surface of the limiting block 501. A spring 503 is movably connected to the inner cavity of the stabilizing hole 502. A stabilizing block 504 that cooperates with the stabilizing hole 502 is fixedly connected to the rear side of the inner cavity of the installation shell 2. The surface of the stabilizing block 504 is movably connected to the inner cavity of the stabilizing hole 502. One side of the two springs 503 opposite to each other is fixedly connected to the surface of the stabilizing block 504.

[0023] With the above scheme: by setting the limiting device 5, when the power distribution cabinet 1 moves to the front side of the installation plate 3, the limiting device 5 has a limiting effect on the position of the power distribution cabinet 1.

[0024] Referring to Figure 4 , a moving shell 6 is fixedly connected to one side of the inner cavity of the installation shell 2 close to the power distribution cabinet 1. Moving blocks 7 that cooperate with the limiting blocks 501 are movably connected to the left and right sides of the inner cavity of the moving shell 6. The surface of the moving block 7 is in contact with the surface of the limiting block 501. One side of the two moving blocks 7 opposite to each other penetrates through the moving shell 6 and extends to the outside of the inner cavity of the moving shell 6.

[0025] Adopt the above solution: By setting the moving shell 6 and the moving block 7, when the extrusion column 8 moves, it will drive the moving block 7 to move along the inner cavity of the moving shell 6. The moving shell 6 has a limiting effect on the moving position of the moving block 7. When the moving block 7 moves, it can drive the limiting block 501 to move.

[0026] Reference Figure 4 , a front side of the moving block 7 is fixedly connected to an extrusion column 8. Two extrusion rotating shells 9 that cooperate with the extrusion column 8 are movably connected to a front side of the moving shell 6 through a rotating shaft. An inner cavity of the extrusion rotating shell 9 is movably connected to a surface of the extrusion column 8.

[0027] Adopt the above solution: By setting the extrusion column 8 and the extrusion rotating shell 9, when the extrusion rotating shell 9 rotates, it can generate an extrusion force on the extrusion column 8. The extrusion column 8 subjected to the extrusion force can drive the moving block 7 to move.

[0028] Reference Figure 4 , a side of the control block 4 close to the power distribution cabinet 1 is fixedly connected to an extrusion frame 10 that cooperates with the extrusion rotating shell 9. A surface of the extrusion frame 10 is movably connected to an inner cavity of the extrusion rotating shell 9.

[0029] Adopt the above solution: By setting the extrusion frame 10, when the control block 4 moves, it can drive the extrusion frame 10 to move along the inner cavity of the extrusion rotating shell 9. The extrusion force of the extrusion frame 10 on the extrusion rotating shell 9 can drive the extrusion rotating shell 9 to rotate through the rotating shaft.

[0030] Reference Figure 2 , a limiting groove 11 that cooperates with the limiting block 501 is formed on a surface of the mounting plate 3. A surface of the limiting block 501 is in contact with an inner cavity of the limiting groove 11.

[0031] Adopt the above solution: By setting the limiting groove 11, when the mounting shell 2 moves to the front side of the mounting plate 3 and the control block 4 is released, the restoring force generated by the spring 503 restoring its shape will drive the limiting block 501 to snap into the inner cavity of the limiting groove 11. The cooperation of the limiting block 501 and the limiting groove 11 has a limiting effect on the position of the power distribution cabinet 1.

[0032] Reference Figure 2 and Figure 3 , plug-in blocks 12 are fixedly connected to both left and right sides at the rear of the power distribution cabinet 1. Plug-in slots 13 that cooperate with the plug-in blocks 12 are formed on both left and right sides at the top of the mounting plate 3. A surface of the plug-in block 12 is in contact with an inner cavity of the plug-in slot 13.

[0033] Adopt the above solution: By setting the plug-in block 12 and the plug-in shell, when the power distribution cabinet 1 moves, it will drive the plug-in block 12 to move into the inner cavity of the plug-in slot 13. The cooperation of the plug-in block 12 and the plug-in slot 13 has a limiting effect on the moving position of the power distribution cabinet 1.

[0034] Working principle of the utility model:

[0035] During use, when it is necessary to conveniently and quickly replace the power distribution cabinet 1 used in coal mine exploitation, first, the user disassembles the power distribution cabinet 1 to be replaced. Then, the user pulls the control block 4 towards the opposite sides of the two control blocks 4. When the control block 4 moves, it will drive the extrusion frame 10 to move along the inner cavity of the extrusion rotating shell 9. The extrusion rotating shell 9 under the extrusion force will rotate along the surface of the extrusion column 8 through the rotating shaft. When the extrusion rotating shell 9 rotates, it will generate an extrusion force on the extrusion column 8. The extrusion column 8 under the extrusion force will drive the two moving blocks 7 to move closer to each other along the inner cavity of the moving shell 6. When the moving block 7 moves, it will drive the two limiting blocks 501 to move towards the closer side. When the limiting block 501 moves, it will drive the stabilizing hole 502 to move along the surface of the stabilizing block 504. When the force generated by the movement of the limiting block 501 causes the spring 503 to undergo elastic deformation. When the limiting block 501 completely moves into the inner cavity of the mounting shell 2, the plug-in block 12 is moved into the inner cavity of the plug-in slot 13, and at the same time, it drives the mounting shell 2 to move onto the surface of the mounting plate 3, and drives the power distribution cabinet 1 to move to the front side of the mounting plate 3. After that, the control block 4 can be released. The restoring force generated by the spring 503 restoring its shape will drive the limiting block 501 to snap into the inner cavity of the limiting slot 11. The cooperation of the limiting block 501 and the limiting slot 11 has a limiting effect on the position of the power distribution cabinet 1. At this time, the power distribution cabinet 1 used in coal mine exploitation is conveniently and quickly replaced.

[0036] To sum up: For this power distribution equipment used in coal mine exploitation, by setting the cooperation of the limiting device 5, the limiting block 501, the stabilizing hole 502, the spring 503 and the limiting slot 11, it solves the problem that the existing power distribution cabinet is a device for centralized management and distribution of electric energy, which can be used in coal mine exploitation. When installing the power distribution cabinet, it is usually installed in a wall-mounted, floor-mounted, embedded or cabinet-mounted manner, and auxiliary installation parts such as bolts are required during installation. If a failure or damage occurs after long-term use of the power distribution cabinet, it needs to be replaced in time. When replacing, multiple bolts need to be removed, and then multiple bolts need to be installed to fix the replaced power distribution cabinet. The method of replacing bolts takes a long time and cannot be done quickly and conveniently. However, there is no component for convenient and quick replacement in the existing power distribution cabinets used in coal mine exploitation.
