[0031] The application will be further described in detail below with reference to the drawings and embodiments.

[0032] With reference to Figures 1 to 7 The embodiment of the application provides a coal preparation plant power-off protection device, which comprises a sliding rod 1, an adjusting assembly 2 is arranged on one side of the sliding rod 1; an auxiliary assembly 3 is arranged on one side of the adjusting assembly 2; the adjusting assembly 2 comprises a sliding block 21, the sliding block 21 is slidably connected to the outer wall of the sliding rod 1, a through groove 22 is formed in the sliding block 21, a screw rod 23 is rotatably connected to the inner wall bottom of the through groove 22, a nut block 25 is threadedly connected to the outer wall of the screw rod 23, a bolt rod 26 is fixedly connected to the bottom of the nut block 25, a knob 24 is fixedly connected to one end of the screw rod 23, and the nut block 25 is slidably connected to the inner wall of the through groove 22. A positioning hole 27 is formed in the inside of the sliding rod 1, and the bolt rod 26 can be inserted into the inside of the positioning hole 27. A chuck 28 is rotatably connected to one side of the sliding block 21, and a circuit breaker 29 is fixedly installed on one side of the chuck 28.

[0033] In specific implementation, when it is necessary to change the position of the circuit breaker 29, the sliding block 21 can be pushed to move the circuit breaker 29 to a suitable position, the knob 24 can be twisted to drive the screw rod 23 to rotate, and the nut block 25 can be driven to move up and down linearly after the screw rod 23 rotates, so that the nut block 25 drives the bolt rod 26 to be reinserted into the positioning hole 27 to be fixed.

[0034] With reference to Figures 1 to 7 In one aspect of the embodiment, the auxiliary assembly 3 comprises an assembly block 31, an insertion block 33 is slidably connected to the inner wall of the assembly block 31, and one end of the insertion block 33 can be inserted into a slot of the chuck 28. A pull rod 32 is fixedly connected to one side of the insertion block 33 and penetrates through one side of the sidewall of the assembly block 31 and is movably connected. A spring 34 is fixedly connected to one side of the insertion block 33, and one end of the spring 34 is fixedly connected to one side of the inner wall of the assembly block 31.

[0035] In specific implementation, the chuck 28 can be rotated to drive the circuit breaker 29 to rotate and be adjusted to a certain inclination angle, so as to be conveniently connected to lines at different positions, the insertion block 33 can be inserted into the slot of the chuck 28 to limit the chuck 28, when it is necessary to adjust the inclination angle of the circuit breaker 29, the insertion block 33 can be moved by pulling the pull rod 32, and the spring 34 is compressed at the same time, when the position of the chuck 28 is adjusted, the pull rod 32 is released to release the spring 34 to pop the insertion block 33 into the slot of the chuck 28 to be re-fixed.

[0036] All the electric equipment in the scheme is powered by an external power supply.

[0037] Working principle: In the inner wall of the distribution box, a slide rod 1 is fixed. When the position of the circuit breaker 29 needs to be adjusted, the slide block 21 is pushed to move the circuit breaker 29 to the appropriate position. At this time, the knob 24 is twisted to drive the screw rod 23 to rotate synchronously. Due to the limiting effect of the through slot 22, the nut block 25 can only move linearly in the up-down direction when the screw rod 23 rotates. With the movement of the nut block 25, the latch rod 26 will be reinserted into the positioning hole 27, thereby realizing the stable fixation of the circuit breaker 29 after position adjustment.

[0038] If the inclination angle of the circuit breaker 29 needs to be adjusted to facilitate connection with lines at different positions, the chuck 28 can be rotated to drive the circuit breaker 29 to rotate. To limit the rotation of the chuck 28, the insert block 33 is arranged to be inserted into the slot of the chuck 28. When the inclination angle needs to be adjusted, the pull rod 32 is pulled, and the insert block 33 moves while compressing the spring 34. After the chuck 28 is adjusted to the desired position, the pull rod 32 is released, and the spring 34 releases the elastic force to pop the insert block 33 back into the slot of the chuck 28, completing the locking after angle adjustment.

[0039] It should be noted that, in this text, relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0040] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
