Technical Field

[0001] This utility model relates to the field of mining frequency converter technology, and more specifically, to a dual-locking safety device for mining frequency converters. Background Technology

[0002] Mining frequency converters are power control devices specifically designed for harsh working conditions such as coal mines and metal mines. They achieve intelligent speed regulation by adjusting the motor's operating frequency, combining energy saving and precise control functions. They adopt an explosion-proof design and have a high protection level, which can resist dust, moisture and corrosive gases. Typical application scenarios include belt conveyors, hoists, water pumps, etc. The power saving rate can reach 30%, effectively reducing mechanical wear of equipment and extending its service life.

[0003] Operators often use dual-locking safety devices to protect the frequency converters used in mining operations. While existing safety devices offer basic protection, they typically employ multiple mechanical locks. This can cause significant problems for operators if the keys are lost or misplaced. In such cases, the devices not only fail to provide basic protection but also create inconvenience for operators. Therefore, improvements are necessary. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, this utility model provides a dual-locking safety device for a mining frequency converter, including a mining frequency converter body 1. A fixing frame 2 is fixedly installed on the lower right corner of the front of the mining frequency converter body 1. A first motor 3 located inside the fixing frame 2 is fixedly installed on the front of the mining frequency converter body 1. A rotating shaft 4 is fixedly sleeved at the other end of the output shaft of the first motor 3. A rotating rod 5 is fixedly sleeved at the other end of the rotating shaft 4. A round rod 6 is fixedly installed on the front of the rotating rod 5. A sleeve rod 7 is movably connected to the outer surface of the round rod 6. A telescopic rod 8 is fixedly connected to the top of the sleeve rod 7. The outer surface of the telescopic rod 8 is movably sleeved with the inside of the fixing frame 2. An electronic combination lock body 9 is fixedly connected to the top of the telescopic rod 8.

[0024] When the first motor 3 starts running, it will cause the rotating shaft 4 to drive the rotating rod 5 to rotate, and the round rod 6 to rotate together. This causes the round rod 6 to squeeze and push the sleeve rod 7, and the sleeve rod 7 to drive the telescopic rod 8 and the electronic combination lock body 9 to move vertically upward under the limiting action of the fixed frame 2.

[0025] Among them, the top of the electronic combination lock body 9 is fixedly connected to the human face recognition device body 10, and the right side of the front of the mining frequency converter body 1 is provided with a vertical groove 12, and the outer surface of the vertical groove 12 is movably connected to the inside of the electronic combination lock body 9.

[0026] Due to the limiting effect of the vertical groove 12, the electronic combination lock body 9 will cause the facial recognition device body 10 to move vertically up and down.

[0027] Among them, the front of the mining frequency converter body 1 is fixedly installed with limit rods 11 located on the left and right sides of the electronic combination lock body 9, and the outer surface of the limit rods 11 is movably connected with the inside of the electronic combination lock body 9.

[0028] This design allows the electronic combination lock body 9 to move vertically under the limiting action of the limiting rod 11.

[0029] Among them, the first rotating plate 13 and the second rotating plate 14 are respectively hinged to the left and right sides of the front of the mining frequency converter body 1. The second rotating plate 14 has a pneumatic cylinder 15 fixedly installed inside. The left side of the pneumatic cylinder 15 is fixedly connected to a connecting plate 16, and the outer surface of the connecting plate 16 is movably connected to the inner surface of the second rotating plate 14.

[0030] The output end of the electronic combination lock body 9 is electrically connected to the input end of the pneumatic cylinder 15. When the pneumatic cylinder 15 starts running, it will cause the connecting plate 16 to move horizontally left and right under the limiting action of the second rotating plate 14.

[0031] Among them, the top and bottom of the left side of the connecting plate 16 are fixedly connected with the insertion rod 17. The other end of the insertion rod 17 passes through the second rotating plate 14 and extends into the interior of the first rotating plate 13 and is movably connected with the interior of the first rotating plate 13.

[0032] When the insertion rod 17 disengages from the interior of the first rotating plate 13, the fixing effect on the first rotating plate 13 and the second rotating plate 14 will be released.

[0033] The top of the face recognition device body 10 is fixedly connected to a housing 18, and a second motor 19 is fixedly installed inside the housing 18. A rotating rod 20 is fixedly sleeved at the other end of the output shaft of the second motor 19, and a rotating rod 21 is fixedly sleeved at the other end of the rotating rod 20. Hollow plates 23 are fixedly connected to both the left and right sides of the front of the face recognition device body 10.

[0034] When the second motor 19 starts running, it will cause the swivel rod 20 to drive the rotating rod 21 to rotate.

[0035] The rotating rod 21 is internally connected to a cleaning plate 22, the outer surface of the cleaning plate 22 is internally connected to the hollow plate 23, and the back of the cleaning plate 22 is internally connected to the front of the human face recognition device body 10.

[0036] When the rotating rod 21 rotates, it will squeeze and push the cleaning plate 22, causing the cleaning plate 22 to move vertically downward along the front of the face recognition device body 10 under the limiting action of the hollow plate 23.

[0037] Working principle and usage process of this utility model:

[0038] The first motor 3 is started, causing the rotating shaft 4 to drive the rotating rod 5 to rotate, and the round rod 6 to rotate together. This causes the round rod 6 to press and push the sleeve rod 7, and the sleeve rod 7 to drive the telescopic rod 8 and the electronic combination lock body 9 to move vertically upward under the limiting action of the fixed frame 2. Finally, the height of the electronic combination lock body 9 and the facial recognition device body 10 is adjusted to the required position. At this time, the operator enters the predetermined password through the electronic combination lock body 9, and the facial recognition device body 10 collects the image for comparison. This not only eliminates the need for the operator to carry a key at all times, bringing convenience to the operator, but also meets the needs of operators of different heights. When the image and password are both correct, the electronic combination lock body 9 controls the pneumatic cylinder 15 to start, causing the connecting plate 16 to drive the insertion rod 17 to move horizontally to the right, and causing the insertion rod 17 to disengage from the interior of the first rotating plate 13, thereby releasing the fixing effect on the first rotating plate 13 and the second rotating plate 14.

[0039] When the face recognition device 10 has been placed for a long time and a lot of dust has accumulated on its surface, the second motor 19 is activated. This causes the rotating rod 20 to rotate, and the rotating rod 21 squeezes and pushes the cleaning plate 22. Under the limiting action of the hollow plate 23, the cleaning plate 22 moves vertically downward along the front of the face recognition device 10, thus cleaning the front of the face recognition device 10 and preventing dust from covering the face recognition device 10 and affecting the subsequent shooting effect.
