DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In this embodiment, the front, rear, left, right, top and bottom are represented by Figure 1 Describes the datum surface. Figure 1-Figure 5, the utility model provides a technical solution:

[0021] A face recognition device for coal mine safety monitoring, comprising a wall mounting plate 1 with mounting holes, a fixing rod 11 fixedly mounted on the left surface of the wall mounting plate 1, a support frame 2 mounted on the left end of the fixing rod 11, a folding frame 3 mounted on the top of the support frame 2, a face punch card recognition device body 4 detachably mounted on the end of the folding frame 3 away from the support frame 2, a dust cover 41 rotatably mounted on the top of the face punch card recognition device body 4, two rubber laminating ribs 411 fixedly mounted in the dust cover 41, after the dust cover 41 is flipped forward, the rubber laminating ribs 411 are attached to the front surface of the face punch card recognition device body 4, and a camera of the face punch card recognition device body 4 is located between the two rubber laminating ribs 411, and a quick connection mechanism 5 is installed between the face punch card recognition device body 4 and the folding frame 3;

[0022] It should be noted that when performing face recognition, in order to prevent the dust cover 41 from autonomously moving to block the camera of the face card recognition device body 4 and affect the recognition effect, Figure 3 As shown, two elastic supporting cards 42 are fixedly installed on the upper surface of the face card recognition body 4. After the dust cover 41 is flipped upward and away from the camera of the face card recognition body 4 for a certain distance, the rear end rubber fitting rib 411 is clamped in the elastic supporting card 42, which can limit the position of the dust cover 41 and prevent it from moving.

[0023] When in use, the wall mounting plate 1 can be fixed to the side wall of the mine with the help of expansion bolts passing through the mounting holes. When performing facial recognition on miners, the dust cover 41 is manually flipped upwards so that it can be clamped in the elastic support card 42 by the rear rubber fitting rib 411 to achieve position limiting, exposing the camera of the face punch card recognition device body 4 for facial recognition punch card. When the miners finish punching in collectively, the last person flips the dust cover 41 back to its original position and re-seals the camera of the face punch card recognition device body 4 to prevent dust.

[0024] In actual application scenarios, the design of the dust cover 41 and the quick-connect mechanism 5 greatly improves the convenience of use and maintenance efficiency of the face punch-in recognition device. The dust cover 41 effectively prevents dust from invading the camera, ensuring the accuracy and stability of recognition; the quick-connect mechanism 5 saves time and labor costs during equipment maintenance, improving work efficiency.

[0025] In a specific mine operation environment, such a design enables the facial clock-in recognition device to better adapt to harsh conditions. The flexible operation of the dust cover 41 and the convenience of the quick-connect mechanism 5 bring significant optimization to the miners' clock-in process and equipment maintenance, ensuring the normal operation of the equipment and accurate data collection.

[0026] It is worth noting that if Figure 4As shown, the quick-connect mechanism 5 includes a limit shell 51 fixedly mounted on the rear surface of the face card recognition body 4, a slot 511 is provided on the lower surface of the limit shell 51, a convex block 52 is slidably mounted in the limit shell 51, and a spring 53 is fixedly mounted between the convex block 52 and the limit shell 51:

[0027] like Figure 5 As shown, an arc groove 31 is provided at the top of the folding frame 3, the size of the arc groove 31 matches the size of the limiting shell 51, a hollow ring 32 is fixedly installed in the arc groove 31, the hollow ring 32 is plugged and installed in the limiting shell 51 through the slot 511, and the protrusion 52 is clamped in the hollow ring 32;

[0028] When the folding frame 3 is connected to the quick-connect mechanism 5, the protrusion 52 is pressed in the direction of the spring 53, so that the hollow ring 32 can be smoothly inserted from the slot 511 into the limiting shell 51. After the insertion is completed, the protrusion 52 is clamped into the hollow ring 32 under the action of the spring 53 to fix it, thereby achieving the fixation of the folding frame 3 and the quick-connect mechanism 5. When disassembling, the reverse operation is performed, pressing the protrusion 52 to disengage it from the hollow ring 32, and then moving the folding frame 3 downward to separate it from the quick-connect mechanism 5. The entire disassembly process is quick and convenient, which can improve the efficiency of disassembly and maintenance of the face card recognition body 4;

[0029] In actual operation, the design mechanism of the quick-connect mechanism 5 is simple and efficient, and can complete the connection and separation of the folding frame 3 and the quick-connect mechanism 5 in a short time, which provides great convenience for the repair and maintenance of the equipment, effectively shortens the equipment downtime for maintenance, and improves work efficiency.

[0030] In order to facilitate the adjustment of the recognition angle of the face punch card recognition device body 4, Figure 2 and Figure 5 As shown, a transfer rod 33 is fixedly installed on the front and rear surfaces of one end of the folding frame 3 close to the supporting frame 2, the transfer rod 33 is rotatably connected to the top of the supporting frame 2, and a stopper 34 is fixedly installed on the outer end of the transfer rod 33, and a plurality of damping washers 35 are sleeved on the outer surface of the transfer rod 33, and the damping washers 35 are arranged between the stopper 34 and the supporting frame 2. When in use, the face punching recognition device body 4 can be flipped with the transfer rod 33 as the axis point to adjust the recognition angle.

[0031] Finally, to facilitate the adjustment of the recognition direction, such as Figure 2 As shown, a hinged damping shaft 12 is fixedly installed on the upper surface of one end of the fixing rod 11 away from the wall mounting plate 1, and the end of the supporting frame 2 away from the folding frame 3 is rotationally connected to the hinged damping shaft 12. There is a certain damping property between the supporting frame 2 and the hinged damping shaft 12, and the recognition direction of the face punching recognition device body 4 can be adjusted by rotating the supporting frame 2.
