Description

Technical Field

[0001] This invention relates to the field of mobile room supporting equipment technology, specifically to a mobile room supporting equipment for safety education and training. Background Technology

[0002] In construction projects, due to the special nature of the site, many non-standard operations can easily lead to danger and injury to workers. Therefore, in this context, construction companies need to provide training and testing to personnel who are newly entering the construction site on basic construction knowledge and construction safety knowledge.

[0003] Patent publication number CN220709835U discloses a safety education device, relating to the field of safety training technology. The device includes a main body with a first side door, a second side door, and a partition door. The partition door is hinged to the second side door. The main body is divided into an experience room and a display storage room by the first and second side doors. The experience room contains an impact mechanism, which includes an impact hammer and a power component. The power component drives the impact hammer. The display storage room contains a display. By organically combining a conventional helmet impact experience device with a safety video playback training device, the device's size and floor space are reduced, making it easier to transport. The door structure separates the experience room and the display location, ensuring the display is closed during impact experience, effectively preventing damage to the display.

[0004] However, the device still has shortcomings: although it can reduce the size of the equipment and the floor space, making it easy to transport, the construction site is often uneven and muddy, which requires the equipment to be placed on a flat surface to prevent the projection or projection components inside the equipment from being tilted, and to prevent the screen or screen from displaying images out of center, causing discomfort to the viewers and reducing their viewing interest. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a supporting device for a mobile safety education and training room, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mobile safety education and training room supporting equipment, comprising a base, with movable components installed at the four corners of the base bottom, a container installed on the top of the base, a protective door installed on the front of the container, a projection component installed on the back of the inner wall of the container, a multimedia component installed at the bottom of the inner wall of the container, a monitoring component installed on the top of the multimedia component, and fixed plates fixedly installed on the left and right sides of the outer wall of the container. Several electro-hydraulic rods are fixedly installed at the bottom of the fixed plates, and the extension ends of the electro-hydraulic rods are connected by springs. A conical block is slidably installed, and the interior of the telescopic end of the electro-hydraulic rod is located on the movement trajectory of the conical block. A telescopic rod is fixedly installed on the top of the inner wall of the telescopic end of the electro-hydraulic rod. Two L-shaped rods are fixedly installed on the outer wall of the telescopic end of the telescopic rod, and a compression ball is fixedly installed on the top of each of the two L-shaped rods. A telescopic ladder block is slidably installed on the outer wall surface of the telescopic rod via a spring. An abutment block is fixedly installed at the bottom of the telescopic end of the telescopic ladder block, and the arc surface of the abutment block is located on the movement trajectory of the arc surface of the compression ball. The rotating component generates rotational force through friction with the ground, thereby driving the base to move. The base drives the container to move synchronously. When the container... When the container is moved from the construction site to the playback location, the electro-hydraulic boom is activated. At this time, the fixing plate limits the electro-hydraulic boom, and simultaneously, the telescopic end of the boom extends downwards. As the telescopic end extends downwards, it drives the conical block to move synchronously. The sharp end of the conical block, under the weight of the container, pierces the ground. The telescopic end of the boom continues to exert force, causing the conical block to penetrate deeper into the ground until the plane of the telescopic end of the boom contacts the ground. The extension length of each telescopic end of the boom can be adjusted independently. When the conical block retracts inwards from the telescopic end of the boom, it pushes the telescopic end of the boom to retract synchronously, causing the L-shaped... As the lever moves upward, the L-shaped lever drives the extrusion ball to move synchronously. The extrusion ball abuts against the arc surface of the contact block at the bottom of the telescopic ladder block, generating a resisting force. The contact block moves away from the center of the telescopic end of the electric hydraulic lever due to the resisting force, pulling the telescopic end of the telescopic ladder block to move synchronously. The telescopic end of the telescopic ladder block is locked into the locking groove on the inner wall of the telescopic end of the electric hydraulic lever, limiting the conical block. When the telescopic end of the electric hydraulic lever returns to its original position, the conical block is pushed back to its original position by the spring force. The conical block pulls the L-shaped lever and the extrusion ball back to their original position. At this time, the extrusion ball no longer contacts the arc surface of the contact block. Both the telescopic ladder block and the telescopic end of the telescopic ladder block return to their original position by the spring force, thus contacting the limit of the conical block.

[0007] According to the above technical solution, the inner wall of the telescopic end of the electric hydraulic rod is provided with several equidistant locking grooves, and the outer wall of the telescopic end of the electric hydraulic rod penetrates the base. The top of the conical block is fixedly installed at the bottom of the telescopic end of the telescopic rod. The telescopic ladder block has a built-in spring, and the arc surface of the locking groove on the inner wall of the telescopic end of the electric hydraulic rod is located on the movement trajectory of the inclined surface of the telescopic ladder block. The outer wall of the telescopic end of the electric hydraulic rod is provided with a stone-breaking device for sweeping away the stones around the conical block when the telescopic end of the electric hydraulic rod supports the container.

[0008] According to the above technical solution, the anti-stone-breaking device includes a flat plate, an H-shaped plate, a hinged plate, a pulley, a rotating rod, and several arc-shaped plates. The flat plate is internally penetrated and fixedly installed on the outer wall surface of the telescopic end of the electric hydraulic rod. The top inner wall of the H-shaped plate is hinged to the outer wall of the flat plate by a torsion spring. The side of the hinged plate away from the center of the flat plate is hinged to the bottom inner wall of the H-shaped plate by a torsion spring. The pulley is rotatably installed on the inner wall of the hinged plate on the side away from the center of the flat plate. Both sides of the rotating rod are fixedly installed on the inner wall of the pulley. Several arc-shaped plates are equidistantly and slidably installed on the outer wall of the rotating rod by springs. The surface of the curved plate is fixedly mounted with a circular plate. When the telescopic end of the electric hydraulic rod moves downward, it drives the flat plate to move synchronously. The flat plate drives the H-shaped plate to move synchronously. The bottom of the H-shaped plate contacts the ground before the telescopic end of the electric hydraulic rod and generates a resistance force. The resistance force between the H-shaped plate and the ground causes the hinge shaft of the H-shaped plate to start rotating. At this time, the H-shaped plate moves away from the center of the flat plate. The H-shaped plate drives the hinge plate to move synchronously. The hinge plate drives the pulley to move synchronously and rubs against the ground. At this time, the pulley starts to rotate due to friction. When the pulley rotates, it drives the rotating rod to rotate. The rotating rod drives the curved plate to rotate.

[0009] According to the above technical solution, the anti-stone-breaking device further includes a U-shaped plate, several convex ball rods, and several grooved blocks. The bottom of the U-shaped plate away from the center of the flat plate is fixedly installed on the top of the hinge plate. The outer wall of the several convex ball rods away from the center of the flat plate penetrates through and is fixedly installed inside the circular plate. The grooved blocks penetrate through and are fixedly installed on the outer wall of the convex ball rods. When the arc plate rotates, it drives the circular plate to rotate, and the circular plate drives the convex ball rods to rotate. When the convex ball rods rotate, the arc surface continuously abuts against the arc surface of the U-shaped plate to generate a resisting force. At this time, the convex ball rods drive the circular plate and the arc plate to slide synchronously along the outer wall of the rotating rod towards the center of the H-shaped plate. After that, the circular plate and the arc plate synchronously return to their original positions with spring force. At the same time, the convex ball rods drive the grooved blocks to slide synchronously at the adjacent included angle of the arc plate.

[0010] According to the above technical solution, the outer wall of the U-shaped plate near the center of the flat plate is located on the circular motion trajectory of the convex ball rod. Several convex ball rods are installed at equal intervals inside the circular plate, and the convex ball rods are located inside the adjacent included angle of the arc plate. Several grooved blocks are distributed at equal intervals on the outer wall surface of the convex ball rods, and the arc surface of the grooved blocks is located inside the included angle of the arc plate. A protective device is provided above the flat plate to prevent damage to the face recognition system.

[0011] According to the above technical solution, the protective device includes a vertical rod, a pressure plate, a push plate, an identification component, and a protective shell. The bottom of the vertical rod is through and fixedly installed at the top edge of the flat plate. The bottom of the pressure plate is fixedly installed at the top of the vertical rod. The top of the push plate is hinged to the bottom edge of the pressure plate by a torsion spring. The bottom of the identification component is slidably installed on the top of the container. The bottom of the protective shell is fixedly installed on the top of the container. The identification component is located inside the protective shell. When the flat plate moves downward, it pulls the vertical rod to move synchronously. The vertical rod drives the pressure plate to move downward. When the pressure plate moves downward, it presses the top hinge shaft of the push plate to rotate. At this time, the pressure plate pushes the push plate forward. The push plate pushes the identification component to slide inside the protective shell towards the front entrance of the container. At this time, the identification component performs facial recognition on the learners entering the container.

[0012] According to the above technical solution, the protective device further includes a horizontal plate, a lead screw, a locking plate, and a hollow plate. The horizontal plate is fixedly installed on the outer wall of the identification component near the center of the container. The back of the lead screw is rotatably installed on the front of the horizontal plate. The locking plate is fixedly installed on the outer wall of the protective shell near the center of the container. The hollow plate is fixedly installed on the outer wall of the protective shell near the center of the container, and the hollow plate is located in front of the locking plate. At the same time, the identification component drives the horizontal plate to move synchronously, and the horizontal plate drives the lead screw to move synchronously. When the lead screw passes through the inside of the locking plate, it is restricted by the non-self-locking spiral groove on the outer wall of the lead screw, and the locking block inside the locking plate contacts the inner wall of the spiral groove of the lead screw, causing the lead screw to generate rotational force and start to rotate. When the lead screw rotates, it drives the elliptical block to rotate. When the elliptical block rotates, its own arc surface continuously abuts against the edge of the hollow plate, generating a resisting force that causes the hollow plate to deform and bend. When the elliptical block no longer abuts the hollow plate, the hollow plate automatically recovers through its own toughness and swings back and forth, generating vibration force.

[0013] According to the above technical solution, the outer wall of the lead screw is slidably installed inside the block plate, an elliptical block is fixedly installed on the front of the lead screw, the edge of the hollow plate away from the center of the container is in contact with the arc surface of the outer wall of the elliptical block, and the hollow plate is tough.

[0014] This invention provides a supporting equipment for a mobile safety education and training room. It has the following beneficial effects:

[0015] (1) This invention uses a fixed plate, an electric hydraulic rod, and a conical block to work together. By relying on the electric hydraulic rod itself to adjust the height, the container is always parallel to the ground when it is on a bumpy road surface. This prevents the projection components inside the container from being tilted and avoids the training screen from being played at a non-centered angle, which would cause discomfort to the viewers and reduce their viewing interest. By using a telescopic rod, an L-shaped rod, a squeezing ball, a telescopic ladder block, and a stop block, the conical block can remain stationary when it contacts the ground to provide balance for the container. This prevents the conical block from shaking under external force interference due to the loose soil and weak compaction, which would cause the angle of the fixed point to change and increase the risk of the electric hydraulic rod tilting and collapsing.

[0016] (2) The present invention, through the setting of the anti-crushing device, through the cooperation of the electric hydraulic rod, plate, H-shaped plate, hinge plate, pulley, rotating rod and arc plate, causes the arc plate to sweep the crushed stone at the bottom of the electric hydraulic rod extension end away from its bottom range, so as to avoid the crushed stone accumulating at the bottom of the electric hydraulic rod extension end, which would reduce the flatness of the electric hydraulic rod extension end with the ground. At the same time, it prevents the crushed stone from hitting into the electric hydraulic rod extension end under the action of gravity, which would lead to accelerated wear and tear on the electric hydraulic rod. Through the cooperation of the U-shaped plate, convex ball rod, groove block and round plate, the arc plate increases the lateral sliding force when sweeping the crushed stone, and avoids the crushed stone hitting the bottom of the electric hydraulic rod extension end upward when sweeping, which would cause the crushed stone to stay at the bottom of the electric hydraulic rod extension end for a second time, thus ensuring the cleanliness of the bottom of the electric hydraulic rod extension end and avoiding a reduction in the crushed stone removal effect.

[0017] (3) The present invention, through the setting of the protective device, through the cooperation of the flat plate, vertical rod, pressure plate, push plate, recognition component and protective shell, ensures that the recognition component is activated only when the container is in use to extend and perform facial recognition on the learners, avoiding the recognition component being exposed to the outside for a long time and the recognition lens becoming blurry due to wind and sun exposure, which reduces the recognition accuracy; through the cooperation of the horizontal plate, lead rod, locking plate, hollow plate and elliptical block, the water droplets on the edge of the protective shell are shaken off when it vibrates, avoiding water droplets falling on the surface of the recognition lens when the recognition component is put into use, which would cause the recognition lens to be blocked and unable to perform facial recognition on the learners, and avoid the learners' attendance records for watching safety education learning becoming invalid and causing the conflict between the learners and the management personnel to intensify later.

[0029] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figures 1-10One embodiment of the present invention is as follows: a mobile safety education and training room supporting equipment includes a base 1, with mobile components 2 at each of the four corners of the bottom of the base 1, a container 21 on the top of the base 1, a protective door on the front of the container 21, a projection component 3 on the back of the inner wall of the container 21, a multimedia component 31 at the bottom of the inner wall of the container 21, a monitoring component 32 on the top of the multimedia component 31, fixed plates 6 fixedly installed on the left and right sides of the outer wall of the container 21, a plurality of electro-hydraulic rods 7 fixedly installed at the bottom of the fixed plates 6, a conical block 8 slidably installed at the bottom of the telescopic end of the plurality of electro-hydraulic rods 7 via springs, and the inside of the telescopic end of the electro-hydraulic rods 7 is located on the movement trajectory of the conical block 8, a telescopic rod 9 fixedly installed at the top of the inner wall of the telescopic end of the electro-hydraulic rods 7, two L-shaped rods 10 fixedly installed on the outer wall of the telescopic end of the telescopic rod 9, a compression ball 11 fixedly installed at the top of each of the two L-shaped rods 10, and a telescopic ladder block 12 slidably installed on the outer surface of the telescopic rod 9 via springs, the telescopic ladder block 12 telescopically extending and retracting. A contact block 13 is fixedly installed at the bottom of the end, and the arc surface of the contact block 13 is located on the arc surface of the extrusion ball 11. At the same time, the multimedia component 31 and the projection component 3 are used to project and play safety education videos. The monitoring component 32 is used to remotely observe and supervise the learners watching the education videos to ensure their attentiveness. Through the above cooperation, the telescopic end of the electric hydraulic rod 7 lifts the base 1 and the container 21. The electric hydraulic rod 7 itself can adjust the height to ensure that the container 21 is always parallel to the ground when it is on the uneven road surface of the construction site. This prevents the projection component 3 inside the container 21 from being at an angle of tilt, and avoids the training screen from playing at a non-centered angle, which would cause discomfort to the viewers and reduce their viewing interest. Through the above cooperation, the cone block 8 can remain stationary when it contacts the ground, providing balance for the container 21. This prevents the cone block 8 from shaking under external force interference due to the loose soil and weak compaction, which would cause the angle of the fixed point to change and increase the risk of the electric hydraulic rod 7 tilting and collapsing.

[0031] The inner wall of the telescopic end of the electric hydraulic rod 7 is provided with several equidistant locking slots, and the outer wall of the telescopic end of the electric hydraulic rod 7 penetrates the base 1. The top of the conical block 8 is fixedly installed at the bottom of the telescopic end of the telescopic rod 9. The telescopic ladder block 12 has a built-in spring, and the arc surface of the locking slot on the inner wall of the telescopic end of the electric hydraulic rod 7 is located on the movement trajectory of the inclined surface of the telescopic ladder block 12. The outer wall of the telescopic end of the electric hydraulic rod 7 is provided with a stone-breaking device 4 for sweeping away the stones around the conical block 8 when the telescopic end of the electric hydraulic rod 7 supports the container 21.

[0032] In use, the rotating component 2 rotates due to friction with the ground, causing the base 1 to move. The base 1 then moves the container 21 synchronously. Simultaneously, the multimedia component 31 and projection component 3 project and play safety education videos. The monitoring component 32 remotely monitors and supervises the attentiveness of those watching the videos. When the container 21 moves to the playback location, the electric hydraulic rod 7 is activated. At this time, the fixing plate 6 limits the electric hydraulic rod 7, and the telescopic end of the electric hydraulic rod 7 extends downwards. This downward extension of the electric hydraulic rod 7 drives the conical block 8 to move synchronously. The sharp end of the conical block 8... Under the weight of container 21, it pierces the ground. Then, the telescopic end of the electric hydraulic rod 7 continuously exerts force, causing the conical block 8 to penetrate deeper into the ground until the plane of the telescopic end of the electric hydraulic rod 7 contacts the ground. The telescopic end of the electric hydraulic rod 7 can be independently adjusted in length. Through this coordination, the telescopic end of the electric hydraulic rod 7 lifts the base 1 and container 21. Relying on the electric hydraulic rod 7 itself for height adjustment, container 21 is always used parallel to the ground when on uneven construction sites. This prevents the projection component 3 inside container 21 from being tilted, avoiding the training screen displaying training images at a non-centered angle, which would cause discomfort and reduce the viewing angle for viewers. Viewing interest; When the conical block 8 retracts into the telescopic end of the electric hydraulic rod 7, the conical block 8 pushes the telescopic end of the telescopic rod 9 to retract synchronously. The telescopic end of the telescopic rod 9 drives the L-shaped rod 10 to move upward. The L-shaped rod 10 drives the extrusion ball 11 to move synchronously. The extrusion ball 11 abuts against the arc surface of the abutment block 13 at the bottom of the telescopic ladder block 12, generating a resisting force. The abutment block 13 moves away from the center of the telescopic end of the electric hydraulic rod 7 through the resisting force and pulls the telescopic end of the telescopic ladder block 12 to move synchronously. The telescopic end of the telescopic ladder block 12 is locked into the locking groove on the inner wall of the telescopic end of the electric hydraulic rod 7, limiting the conical block 8. When the telescopic end of the electric hydraulic rod 7 returns to its original position, the conical block 8 is spring-loaded. The force pushes the cone block 8 to reset, pulling the L-shaped rod 10 and the compression ball 11 back to their original positions. At this time, the compression ball 11 no longer contacts the arc surface of the contact block 13. The telescopic ladder block 12 and its telescopic end are both reset by springs, thus contacting the limit of the cone block 8. Through the above cooperation, the cone block 8 can remain stationary for a long time when it contacts the ground, providing balance for the container 21. When the cone block 8 moves upward, it generally retracts into the telescopic end of the electric hydraulic rod 7, and the bottom of the telescopic end of the electric hydraulic rod 7 will also contact the ground. Compared with the tip support at the bottom of the cone block 8, the bottom of the telescopic end of the electric hydraulic rod 7 contacting the ground can further improve the stability of the device.

[0033] Please see Figures 1-10 Based on the above embodiments, another embodiment of the present invention further includes a stone-breaking device 4;

[0034] The anti-gravel device 4 includes a flat plate 41, an H-shaped plate 42, a hinged plate 43, a pulley 44, a rotating rod 45, and several arc-shaped plates 46. The flat plate 41 is internally penetrated and fixedly installed on the outer wall surface of the telescopic end of the electric hydraulic rod 7. The top inner wall of the H-shaped plate 42 is hinged to the outer wall of the flat plate 41 by a torsion spring. The side of the hinged plate 43 away from the center of the flat plate 41 is hinged to the bottom inner wall of the H-shaped plate 42 by a torsion spring. The pulley 44 is rotatably installed on the inner wall of the hinged plate 43 away from the center of the flat plate 41. The rotating rod 45 is fixedly installed on both sides of the sliding plate 46. On the inner wall of wheel 44, several arc-shaped plates 46 are equidistantly and slidably mounted on the outer wall surface of rotating rod 45 via springs. A circular plate is fixedly installed on the front of the arc-shaped plates 46. Through the above cooperation, the arc-shaped plates 46 sweep the gravel at the bottom of the telescopic end of the electric hydraulic rod 7 away from its bottom, so as to avoid the gravel accumulating at the bottom of the telescopic end of the electric hydraulic rod 7, which would reduce the flatness between the telescopic end of the electric hydraulic rod 7 and the ground. At the same time, it prevents the gravel from hitting into the inside of the telescopic end of the electric hydraulic rod 7 under the action of gravity, which would lead to accelerated wear and tear on the electric hydraulic rod 7.

[0035] The anti-crushing device 4 also includes a U-shaped plate 47, several convex ball rods 48, and several grooved blocks 49. The bottom of the U-shaped plate 47, which is away from the center of the flat plate 41, is fixedly installed on the top of the hinge plate 43. The outer wall of the several convex ball rods 48, which is away from the center of the flat plate 41, is penetrated and fixedly installed inside the circular plate. The grooved blocks 49 are penetrated inside and fixedly installed on the outer wall of the convex ball rods 48. Through the above cooperation, the arc plate 46 increases the lateral sliding force when sweeping the crushed stone, and avoids the crushed stone from hitting the bottom of the telescopic end of the electric hydraulic rod 7 upward when sweeping, which would cause the crushed stone to stay at the bottom of the telescopic end of the electric hydraulic rod 7 for a second time, thus ensuring the cleanliness of the bottom of the telescopic end of the electric hydraulic rod 7 and avoiding a reduction in the sweeping effect of the crushed stone.

[0036] The outer wall of the U-shaped plate 47 near the center of the plate 41 is located on the circular motion trajectory of the convex ball rod 48. Several convex ball rods 48 are equidistantly installed inside the circular plate, and the convex ball rods 48 are located inside the adjacent included angle of the arc plate 46. Several grooved blocks 49 are equidistantly distributed on the outer wall surface of the convex ball rod 48, and the arc surface of the grooved blocks 49 is located inside the included angle of the arc plate 46. A protective device 5 is provided above the plate 41 to prevent damage to the face recognition system.

[0037] In use, when the telescopic end of the electric hydraulic rod 7 moves downward, it drives the flat plate 41 to move synchronously. The flat plate 41 drives the H-shaped plate 42 to move synchronously. The H-shaped plate 42 contacts the ground before the bottom of the telescopic end of the electric hydraulic rod 7 and generates a resistance force. This resistance force causes the hinge shaft of the H-shaped plate 42 to start rotating. At this time, the H-shaped plate 42 moves away from the center of the flat plate 41. The H-shaped plate 42 drives the hinge plate 43 to move synchronously. The hinge plate 43 drives the pulley 44 to move synchronously and rub against the ground. At this time, the pulley 44 starts to rotate due to friction. When the pulley 44 rotates, it drives the rotating rod 45 to rotate. The rotating rod 45 drives the arc plate 46 to rotate. Through the above coordination, the arc plate 46 sweeps the gravel at the bottom of the telescopic end of the electric hydraulic rod 7 away from its bottom, preventing the gravel from accumulating at the bottom of the telescopic end of the electric hydraulic rod 7, which would reduce the flatness between the telescopic end of the electric hydraulic rod 7 and the ground, and at the same time prevent... Under the influence of gravity, the gravel impacts the telescopic end of the electro-hydraulic rod 7, leading to increased wear and tear on the rod. When the arc-shaped plate 46 rotates, it drives the circular plate to rotate, which in turn drives the convex ball rod 48 to rotate. As the convex ball rod 48 rotates, its arc surface continuously contacts the arc surface of the U-shaped plate 47, generating a resisting force. At this time, the convex ball rod 48 drives the circular plate and the arc-shaped plate 46 to slide synchronously along the outer wall of the rotating rod 45 towards the center of the H-shaped plate 42. Afterwards, the circular plate and the arc-shaped plate 46 return to their original positions synchronously due to spring force. Simultaneously, the convex ball rod 48 drives the grooved block 49 to slide synchronously at the adjacent angle of the arc-shaped plate 46. This combination increases the lateral sliding force when the arc-shaped plate 46 sweeps the gravel, preventing the gravel from impacting the bottom of the telescopic end of the electro-hydraulic rod 7 and causing a rebound. This prevents the gravel from re-entering the bottom of the telescopic end of the electro-hydraulic rod 7, ensuring the cleanliness of the bottom and avoiding a reduction in the gravel removal effect.

[0038] Please see Figures 1-10 Based on the above embodiments, another embodiment of the present invention further includes a protective device 5;

[0039] The protective device 5 includes a vertical rod 51, a pressure plate 52, a push plate 53, an identification component 54, and a protective shell 55. The bottom of the vertical rod 51 is inserted through and fixedly installed at the top edge of the flat plate 41. The bottom of the pressure plate 52 is fixedly installed at the top of the vertical rod 51. The top of the push plate 53 is hinged to the bottom edge of the pressure plate 52 by a torsion spring. The bottom of the identification component 54 is slidably installed on the top of the container 21. The bottom of the protective shell 55 is fixedly installed on the top of the container 21. The identification component 54 is located inside the protective shell 55. Through the above cooperation, the identification component 54 is only activated to extend and perform facial recognition on the learner when the container 21 is in use, avoiding the identification component 54 being exposed to the outside for a long time and the wind and sun causing the recognition lens to blur and reduce the recognition accuracy.

[0040] The protective device 5 also includes a horizontal plate 56, a lead screw 57, a locking plate 58, and a hollow plate 59. The horizontal plate 56 is fixedly installed on the outer wall of the identification component 54 near the center of the container 21. The lead screw 57 is rotatably installed on the front of the horizontal plate 56. The locking plate 58 is fixedly installed on the outer wall of the protective shell 55 near the center of the container 21. The hollow plate 59 is fixedly installed on the outer wall of the protective shell 55 near the center of the container 21, and is located in front of the locking plate 58. Through the above cooperation, when the protective shell 55 vibrates, the water droplets on its edge will be shaken off, preventing water droplets from dripping onto the surface of the identification lens when the identification component 54 is put into use, which would cause the identification lens to be blocked and unable to perform facial recognition on the learners, thus preventing the learners' attendance records for safety education from becoming invalid and causing the conflict between the learners and the management personnel to intensify later.

[0041] The lead screw 57 is slidably installed inside the locking plate 58 through the outer wall. An elliptical block is fixedly installed on the front of the lead screw 57. The edge of the hollow plate 59 away from the center of the container 21 contacts the arc surface of the outer wall of the elliptical block, and the hollow plate 59 is flexible.

[0042] In use, when the flat plate 41 moves downward, it pulls the vertical rod 51 to move synchronously. The vertical rod 51 drives the pressure plate 52 to move downward. When the pressure plate 52 moves downward, it presses the top hinge shaft of the push plate 53 to rotate. At this time, the pressure plate 52 pushes the push plate 53 to move forward. The push plate 53 pushes the recognition component 54 to slide inside the protective shell 55 towards the front entrance of the container 21. At this time, the recognition component 54 performs facial recognition on the learners entering the container 21. Through the above coordination, the recognition component 54 is only activated to extend and perform facial recognition on the learners when the container 21 is in use, avoiding the recognition component 54 being exposed to the elements for a long time, which may cause the recognition lens to blur and reduce the recognition accuracy. At the same time, the recognition component 54 drives the horizontal plate 56 to move synchronously. The horizontal plate 56 drives the lead screw 57 to move synchronously. When the lead screw 57 passes inside the locking plate 58, it moves through the screw... The non-self-locking spiral groove on the outer wall of rod 57 restricts the movement, and the contact between the internal block of the locking plate 58 and the inner wall of the spiral groove of the lead screw 57 causes the lead screw 57 to generate rotational force and begin to rotate. When the lead screw 57 rotates, it drives the elliptical block to rotate. When the elliptical block rotates, its own arc surface continuously abuts against the edge of the hollow plate 59, generating a resisting force that causes the hollow plate 59 to deform and bend. When the elliptical block no longer abuts the hollow plate 59, the hollow plate 59 automatically recovers through its own toughness and swings back and forth, generating vibration force. Through the above cooperation, when the protective shell 55 vibrates, it shakes off the water droplets present on its own edge, preventing water droplets from dripping onto the surface of the recognition lens when the recognition component 54 is put into use, which would cause the recognition lens to be blocked and unable to perform facial recognition on the learner, thus preventing the learner's safety education check-in record from becoming invalid and causing the conflict between the learner and the management personnel to intensify later.
