Description

Technical Field

[0001] This utility model relates to the field of fingerprint recognition device technology, and more specifically, to a fingerprint recognition device for underground equipment in coal mines. Background Technology

[0002] To strengthen equipment management and prevent non-professionals from operating special equipment such as tunneling and anchoring machines, which could lead to injuries or fatalities, fingerprint verification devices are usually installed on tunneling and anchoring machines. These devices are installed on the side of the machine's display screen and the operator's fingerprint is entered into the system. Before powering on the equipment each time, fingerprint verification must be performed and the machine can only be started after the fingerprint is correctly identified.

[0003] However, due to the large amount of dust generated during underground coal mine operations, and the clothing of equipment operators also accumulates dust, when the fingerprint verification box is opened, dust from the air and the operator's clothing will fall onto the fingerprint scanner. The fingerprint scanner screen is usually recessed inside the housing. Although this makes it easier for operators to quickly locate the fingerprint collection position, this recessed design causes dust to accumulate in the groove, resulting in inaccurate fingerprint recognition. Therefore, we propose a fingerprint recognition device for underground coal mine equipment. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a fingerprint recognition device for underground equipment in coal mines, aiming to solve to some extent the technical problem in the prior art where the recessed design easily leads to dust accumulation in the groove, causing inaccurate fingerprint recognition by the fingerprint collector.

[0005] The technical solution of this utility model is as follows: a fingerprint recognition device for underground equipment in coal mines, including a wiping assembly and a special equipment fingerprint recognition device. The wiping assembly includes a slider and a slider rod. A rotatable shaft is installed in the groove at the bottom of the slider. A wiping plate is fixedly installed on the outer wall of the shaft. Torsion springs are sleeved at both ends of the shaft. A detachable nylon brush is installed on the outer wall of the wiping plate. The special equipment fingerprint recognition device includes a fingerprint collector fixedly installed on its outer wall. Multiple blocking components are fixedly installed on the outer wall of the fingerprint collector.

[0006] Preferably, one end of the torsion spring is fixedly connected to the slider, and the other end of the torsion spring is fixedly connected to the wiping plate.

[0007] Preferably, it also includes a fingerprint verification box, an alarm is installed on the top of the fingerprint verification box, and a door is hinged to the outer wall of the fingerprint verification box.

[0008] Preferably, the special equipment fingerprint recognition device is located inside the fingerprint confirmation box, and a fixing ear is fixedly connected to the outer wall of the special equipment fingerprint recognition device. The fixing ear is fixedly installed on the inner wall of the fingerprint confirmation box by bolts.

[0009] Preferably, the fingerprint recognition device for special equipment has side plates fixedly installed on both sides of the fingerprint collector on its outer wall. Each side plate has a sliding hole on its outer wall and two support blocks are fixedly connected to each side plate. A sliding rod is fixedly connected between the two support blocks on the same side plate, and a spring is sleeved on the outer wall of each sliding rod.

[0010] Preferably, extension rods are fixedly installed on both sides of the slider, and connection holes are opened on the outer walls of the extension rods. The ends of the sliders pass through the connection holes and extend to their outer sides.

[0011] Preferably, one end of the spring is fixedly connected to the support block, and the other end of the spring is fixedly connected to the extension rod.

[0012] Preferably, the diameter of the connecting hole is larger than the diameter of the slide rod, and a roller is rotatably connected to the outer wall of the extension rod, with the roller making rolling contact with the inner wall of the slide hole.

[0013] Preferably, a lever is fixedly connected to the outer wall of the slider.

[0014] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0015] 1. Under the torsion of the torsion spring, the wiping plate pushes the nylon brush towards the side closest to the fingerprint recognition device of the special equipment. When the nylon bristles on the nylon brush are blocked by the blocking component, the nylon brush moves and the bristles bend elastically. When the bent bristles pass the blocking component, they release elasticity, causing the bristles to rub against the surface of the fingerprint collector, thereby cleaning the dust on the surface of the fingerprint collector. Under the elasticity of the nylon bristles, the bristles can clean the dust more effectively. At the same time, it can clean the dust stuck in the dead corners of the fingerprint collector.

[0016] 2. When the extension rod moves, it can drive the roller to move, so that the roller rolls along the inner wall of the sliding hole. At the same time, the diameter of the connecting hole is larger than the diameter of the sliding rod, and the roller can replace the sliding between the extension rod and the sliding rod, reducing the friction between the structures.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 3 , Figure 4 and Figure 5 As shown, a fingerprint recognition device for underground equipment in a coal mine includes a wiping assembly and a special equipment fingerprint recognition device 4. The wiping assembly includes a slider 9 and a slider rod 19. A rotatable shaft 12 is installed in the groove at the bottom of the slider 9. A wiping plate 14 is fixedly installed on the outer wall of the shaft 12. Torsion springs 13 are sleeved on both ends of the shaft 12. A detachable nylon brush 15 is installed on the outer wall of the wiping plate 14. The special equipment fingerprint recognition device 4 includes a fingerprint collector 6 fixedly installed on its outer wall. Multiple blocking parts 21 are fixedly installed on the outer wall of the fingerprint collector 6. One end of the torsion spring 13 is fixedly connected to the slider 9, and the other end of the torsion spring 13 is fixedly connected to the wiping plate 14.

[0025] In the above structure, under the torsion of the torsion spring 13, the wiping plate 14 pushes the nylon brush 15 to press towards the side close to the fingerprint recognition device 4 of the special equipment. When the nylon bristles on the nylon brush 15 are blocked by the blocking member 21, the nylon brush 15 moves and the nylon bristles bend elastically. When the bent bristles pass the blocking member 21, they release elastically, causing the bristles to rub against the surface of the fingerprint collector 6, thereby cleaning the dust on the surface of the fingerprint collector 6. Under the elasticity of the nylon bristles, the bristles can clean the dust more effectively. At the same time, the dust stuck in the dead corner of the fingerprint collector 6 can be cleaned.

[0026] like Figure 1 As shown, it also includes a fingerprint confirmation box 1, an alarm 3 is installed on the top of the fingerprint confirmation box 1, and a door 2 is hinged to the outer wall of the fingerprint confirmation box 1.

[0027] In the above structure, the fingerprint collector 6 is used for fingerprint collection. When the fingerprint collector 6 collects a correct fingerprint, it feeds the fingerprint information back to the special equipment fingerprint recognition device 4. The special equipment fingerprint recognition device 4 uses the uniqueness of fingerprints to convert the correct fingerprint information into an analog signal and transmits it to the device. At this time, the device is powered normally. When the fingerprint recognition is incorrect, the fingerprint collector 6 feeds the fingerprint information back to the special equipment fingerprint recognition device 4. The special equipment fingerprint recognition device 4 triggers the alarm 3 to provide an alarm prompt. The special equipment fingerprint recognition device 4 is a publicly available device and is existing technology. Its connection relationship with the alarm 3 and the fingerprint collector 6 is also a common connection method in existing technology, which will not be elaborated on here.

[0028] like Figure 2 As shown, the special equipment fingerprint recognition device 4 is located inside the fingerprint confirmation box 1. The outer wall of the special equipment fingerprint recognition device 4 is fixedly connected to a fixing ear 5, which is fixedly installed on the inner wall of the fingerprint confirmation box 1 by bolts. The fixing ear 5 can fix the special equipment fingerprint recognition device 4 by bolts.

[0029] like Figure 3 and Figure 4 As shown, the fingerprint recognition device 4 of special equipment has side plates 7 fixedly installed on both sides of the fingerprint collector 6. The outer wall of the side plate 7 is provided with sliding holes 8. Two support blocks 18 are fixedly connected to the outer wall of the side plate 7. A sliding rod 19 is fixedly connected between the two support blocks 18 on the same side plate 7. A spring 20 is sleeved on the outer wall of the sliding rod 19. Extension rods 10 are fixedly installed on both sides of the slider 9. The outer wall of the extension rod 10 is provided with connecting holes 17. The end of the sliding rod 19 passes through the connecting hole 17 and extends to its outer side. One end of the spring 20 is fixedly connected to the support block 18, and the other end of the spring 20 is fixedly connected to the extension rod 10.

[0030] like Figure 3 and Figure 4 As shown, the diameter of the connecting hole 17 is larger than the diameter of the slide rod 19. A roller 16 is rotatably connected to the outer wall of the extension rod 10, and the roller 16 rolls in contact with the inner wall of the slide hole 8. A lever 11 is fixedly connected to the outer wall of the slider 9.

[0031] Working principle: In the non-operational state, the nylon brush 15 on the inner side of the wiping plate 14 covers the fingerprint collector 6. During operation, by pushing the toggle block 11 upward, the toggle block 11 drives the slider 9 to move upward. The slider 9 drives the extension rod 10 to move upward along the slide rod 19, thereby squeezing the spring 20. When the slider 9 moves upward, it drives the wiping plate 14 to move, thereby removing the wiping plate 14 from the fingerprint collector 6. The operator presses their finger on the fingerprint collector 6 to collect the fingerprint.

[0032] After collection, release the lever 11. Under the elastic force of the spring 20, the slider 9 drives the wiping plate 14 to move downward. Under the torsion force of the torsion spring 13, the wiping plate 14 pushes the nylon brush 15 to press towards the side of the special equipment fingerprint recognition device 4. When the nylon bristles on the nylon brush 15 are blocked by the blocking member 21, the nylon bristles will bend elastically when the nylon brush 15 moves. When the bent bristles pass the blocking member 21, they will release elastically, causing the bristles to rub against the surface of the fingerprint collector 6, thereby cleaning the dust on the surface of the fingerprint collector 6. Under the elastic force of the nylon bristles, the bristles can clean the dust more effectively. At the same time, the dust stuck in the dead corners of the fingerprint collector 6 can be cleaned.
