Description

Technical Field

[0001] This utility model relates to the field of dual-circuit power supply technology, specifically a dual-circuit power supply converter device for mines. Background Technology

[0002] Dual-circuit power supply, also known as dual-circuit power supply, is a type of power supply line that mainly consists of two power supply lines and a switching device. The lines can originate from different busbars within the same substation or from different substations, and have the same voltage level. The switching between the faulty line and the backup line is achieved manually or automatically. When one line loses power, the switching device ensures that the load is transferred to the other normal line, and switches back to the initial state once the original line is restored.

[0003] This power supply method requires that the two circuits be independent, and the terminal equipment can maintain operation through the backup circuit. According to the GB50052-2009 standard, the dual circuits can be drawn from different busbars in the same substation, but a single-power-supply dual-circuit system carries the risk of a complete power outage due to a busbar fault. It is mainly used in secondary load scenarios such as mines, hospitals, banks, and transportation hubs, as well as for emergency load protection such as elevators and fire protection in Class II high-rise residential buildings.

[0004] Existing dual-circuit power supply converters are inconvenient to use for vibration damping. Because the ore is located in a high-vibration-frequency zone, these converters are prone to damage or wire detachment due to vibration. Therefore, we propose a dual-circuit power supply converter for mining. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0033] A dual-circuit power supply converter device for mining includes a support base 1. The support base 1 has an internal receiving groove 15. A fixing rod 5 is fixedly connected to the inner wall of the receiving groove 15. A movable block 6 is movably connected to the surface of the fixing rod 5. A connecting through hole 7 is opened in the inner wall of the movable block 6. A first support block 8 is fixedly connected to the top of the movable block 6. A vibration damper 9 is fixedly connected to the surface of the first support block 8. A vibration damping spring 10 is sleeved on the surface of the vibration damper 9.

[0034] The inner wall of the first support block 8 is fixedly connected to the first connecting shaft 11. The surface of the first connecting shaft 11 is movably connected to the movable rod 12. The top of the movable rod 12 is movably connected to the second connecting shaft 13. The surface of the second connecting shaft 13 is fixedly connected to the second support block 14. The top of the second support block 14 is fixedly connected to the limit block 2. The top of the limit block 2 is fixedly connected to the protrusion block 3. The top of the protrusion block 3 is fixedly connected to the conversion device body 4. The surface of the conversion device body 4 is arrayed with several circuit connectors 16. Through the arrangement of the support base 1, the conversion device body 4, the first support block 8, the vibration damper 9, the vibration damping spring 10, the first connecting shaft 11, the movable rod 12, the second connecting shaft 13, the second support block 14, the receiving groove 15, and the circuit connectors 16, it is convenient to buffer the vibration, thereby improving the vibration damping effect. It solves the problem that the circuit connection is easy to fall off and separate after being vibrated, and solves the problem of damage caused by collision, thereby improving the safety during use.

[0035] In this embodiment, four shock absorbers 9 are symmetrically distributed in pairs, and the four shock absorbers 9 are fixed to the inner wall of the receiving groove 15, which facilitates the buffering of the damping spring 10 through the shock absorbers 9.

[0036] In this embodiment, the first support block 8 forms a telescopic structure with the damper 9 through the damping spring 10, and the damping spring 10 is a compression spring, which is beneficial for damping work through the damping spring 10.

[0037] In this embodiment, the limiting block 2 and the protruding block 3 are distributed in a "T" shape, and the top of the protruding block 3 extends into the interior of the receiving groove 15. By setting the limiting block 2 and the protruding block 3, the sliding of the conversion device body 4 is conveniently limited, thereby further improving the stability of the conversion device body 4 during use and preventing the conversion device body 4 from falling off and separating.

[0038] In this embodiment, the movable block 6 is slidably connected to the fixed rod 5 through the connecting through hole 7, and the fixed rod 5 has a smooth surface. The arrangement of the fixed rod 5, the movable block 6 and the connecting through hole 7 facilitates the support and guidance of the sliding of the first support block 8, thereby improving the stability of the sliding of the first support block 8 and preventing the problem of displacement during sliding.

[0039] In this embodiment, the first support block 8 is arranged in a U-shape, and the movable rod 12 is rotatably connected to the first support block 8 through the first connecting shaft 11, which facilitates the sliding of the first support block 8 through the first connecting shaft 11 when the movable rod 12 rotates.

[0040] In this embodiment, the movable rod 12 is rotatably connected to the second support block 14 via the second connecting shaft 13, and the second support block 14 is arranged in a U-shape, which facilitates the second support block 14 to drive the movable rod 12 to rotate via the second connecting shaft 13 when it is raised or lowered.

[0041] In this embodiment, when the dual-circuit power supply converter device for mining is used, the main body 4 of the converter device is subjected to vibration, which causes the protruding block 3 to descend. This causes the protruding block 3 to drive the limiting block 2 to descend, which in turn causes the limiting block 2 to drive the second support block 14 to descend. The second support block 14 drives the movable rod 12 to rotate via the second connecting shaft 13. This causes the movable rod 12 to drive the first support block 8 to slide via the first connecting shaft 11. This causes the first support block 8 to drive the movable block 6 to slide via the fixed rod 5. As a result, the first support block 8 causes the damping spring 10 to compress and deform. The damper 9 absorbs the elasticity of the damping spring 10, thus damping the sliding of the first support block 8. This improves the stability of the main body 4 of the converter device during use and solves the problem that the main body 4 of the converter device is easily damaged or the lines are disconnected when subjected to vibration.
