Detailed Implementation

[0051] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0052] like Figures 1-9 As shown, a personnel control device for a specific area includes: a U-shaped frame 1, which includes: a U-shaped plate 101, a horizontal plate 102 and a square plate 103. The horizontal plate 102 is fixed on the upper back of the U-shaped plate 101, and a square plate 103 is fixed on both sides of the back of the horizontal plate 102. The two square plates 103 are respectively provided with four bolt holes on the front. A T-shaped guide rail 2 is provided at the bottom of the U-shaped frame 1.

[0053] Servo motor 3 is fixedly installed on the left side of U-shaped frame 1;

[0054] Screw 4 is installed through and rotatably on the left and right sides of the inner wall of U-shaped frame 1. The outer wall of screw 4 is provided with a non-self-locking threaded groove.

[0055] The internal threaded tube 5 is slidably mounted on the outer wall of the screw 4, and the inner wall of the internal threaded tube 5 meshes with the outer wall of the threaded groove of the screw 4.

[0056] Sleeve 6 is fixed in the middle of the bottom surface of the inner threaded tube 5. The inner wall of sleeve 6 is slidably connected to the outer wall of T-shaped guide rail 2. Sleeve 6 is located above T-shaped guide rail 2.

[0057] Square platform 7 is fixed in the middle of the top surface of the internal threaded tube 5;

[0058] Gear 8 is rotatably mounted in the middle of the top surface of the square platform 7;

[0059] Long strip 9 is fixed to the left and right sides of the inner wall of U-shaped frame 1, and long strip 9 is located behind gear 8;

[0060] Rack 10 is fixed to the front of the long strip plate 9, and the front of rack 10 meshes with the outer wall of gear 8.

[0061] Camera 11 is fixedly mounted on the top surface of gear 8. Camera 11 has a lens on the front and a built-in face recognition module.

[0062] Protective plate 12 is fixed to the top surface of camera 11;

[0063] Camera 11 is used to identify the movements of people in a specific area;

[0064] When using this equipment, the U-shaped plate 101 supports the horizontal plate 102, and the horizontal plate 102 supports the square plate 103. The operator installs the U-shaped frame 1 above the chemical plant gate through the bolt holes of the square plate 103. The operator starts the servo motor 3, and the shaft of the servo motor 3 begins to rotate back and forth. The shaft of the servo motor 3 drives the screw 4 to rotate back and forth. At the same time, the sleeve block 6 is restricted by the T-shaped guide rail 2, causing the inner thread tube 5 to move back and forth on the thread groove of the screw 4. The inner thread tube 5 drives the sleeve block 6 to move back and forth, and the sleeve block 6 slides back and forth on the T-shaped guide rail 2. The inner thread tube 5 drives the square platform 7 to move back and forth, and the square platform 7 drives the gear 8 to move back and forth. The U-shaped frame 1 supports the long strip plate 9, and the long strip plate 9 supports the rack 10. When gear 8 moves to the left, it rotates clockwise on the platform 7 under the constraint of the tooth gap of rack 10. Conversely, when gear 8 moves to the right, it rotates counterclockwise on the platform 7. Gear 8 drives camera 11 to rotate clockwise and counterclockwise, and camera 11 drives protective plate 12 to rotate clockwise and counterclockwise. Protective plate 12 is used to block backlight from above camera 11. During the rotation, camera 11 identifies the faces and movements of people in specific areas through the face recognition module built into camera 11, identifies and locates people in the chemical plant area, and provides real-time perception and warning. This avoids the problem that camera 11 cannot identify the faces and movements of people from the side when the control equipment is monitoring a specific area, resulting in poor recognition effect of camera 11.

[0065] The outer wall of the platform 7 is provided with an oil wiping device 13, which is used to wipe lubricating oil onto the surface of the screw 4. The top surface of the oil wiping device 13 is provided with a support device 14, which is used to support the bottom of the camera 11.

[0066] The oiling device 13 includes: a spiral frame 131, which is fixed to the outer wall of the square platform 7;

[0067] Two connecting plates 132 are fixed to the left and right sides of the loop frame 131;

[0068] Ring 133 is fixed to the bottom surface of the two connecting plates 132 respectively;

[0069] The sponge ring 134 is fixed to the inner wall of the two rings 133 respectively. The inner wall of the sponge ring 134 slides in contact with the outer wall of the screw 4. The loop frame 131 is located above the inner screw tube 5. The two connecting plates 132 are located on the left and right sides of the inner screw tube 5. The sponge ring 134 is filled with lubricating oil and is used to wipe the outer surface of the screw 4.

[0070] While the square platform 7 drives the gear 8 to move back and forth, the square platform 7 drives the loop frame 131 to move back and forth, the loop frame 131 drives the connecting plate 132 to move back and forth, the connecting plate 132 drives the ring 133 to move back and forth, the ring 133 drives the sponge ring 134 to move back and forth. During the back and forth movement of the sponge ring 134, the sponge ring 134 wipes the lubricating oil on the surface of the screw 4, thereby avoiding the problem of poor monitoring effect of the camera 11 due to the movement jamming during the monitoring of the control equipment in a specific area.

[0071] A ring frame 135 is fixed to the front of each of the two rings 133. Straight rods 136 are fixed to the left and right sides of the inner wall of the U-shaped plate 101. The straight rods 136 are located in front of the inner screw tube 5. The outer wall of the straight rods 136 slides in contact with the inner wall of the two ring frames 135. Two ring pieces 137 are fixed to the outer wall of the straight rods 136. The two ring pieces 137 are used to limit the two ring frames 135.

[0072] While the connecting plate 132 drives the ring 133 to move back and forth, the ring 133 drives the ring frame 135 to move back and forth. The ring frame 135 slides back and forth on the straight rod 136. The ring plate 137 limits the ring frame 135, thereby avoiding the problem of unclear monitoring caused by excessive rotation of the camera 11 during the monitoring of a specific area by the control equipment.

[0073] The support device 14 includes: a bending frame 141, which passes through and is fixed to the top surface of the two ring frames 135;

[0074] Two supports 142 are fixed above the outer wall of the bending frame 141;

[0075] The grooved arc frame 143 is fixed to the top surface of the two supports 142;

[0076] The circular block 144 is fixed on the bottom surface of the camera 11. The outer wall of the circular block 144 slides in contact with the inner wall of the slotted frame 143. The two supports 142 are set as Y-shaped structures. The top surface of the slotted frame 143 slides in contact with the bottom surface of the camera 11. The slotted frame 143 is used to support the bottom of the camera 11.

[0077] While the ring 133 drives the ring frame 135 to move back and forth, the ring frame 135 drives the curved frame 141 to move back and forth, the curved frame 141 drives the support frame 142 to move back and forth, the support frame 142 drives the slotted arc frame 143 to move back and forth, and at the same time, the camera 11 drives the circular block 144 to rotate back and forth. The circular block 144 rotates in the slotted arc frame 143, which supports the bottom of the camera 11, reducing the shaking of the camera 11 when it moves. This avoids the problem of blurry images caused by the camera 11 shaking during the monitoring of a specific area.

[0078] Two support rods 145 are fixed to the bottom of the outer wall of the bending frame 141, and two spiral frames 146 are fixed to the top of the outer wall of the bending frame 141. The top ends of the two support rods 145 are slidably installed on the bottom surface of the two spiral frames 146. Springs 147 are respectively installed between the bottom surface of the two spiral frames 146 and the outer wall of the two support rods 145, and the two springs 147 are sleeved on the outer wall of the support rods 145.

[0079] While the bending frame 141 drives the support frame 142 to move back and forth, the bending frame 141 also drives the platform 145 to move back and forth, and the bending frame 141 drives the return frame 146 to move back and forth. The compressed spring 147 supports the bottom of the return frame 146. Under the elastic force of the compressed spring 147, the stability of the bending frame 141 when it is supported is improved, thereby avoiding the problem that the bending frame 141 will not provide good support due to the amplitude caused by the movement of the bending frame 141 during the monitoring of the control equipment in a specific area.

[0080] Working principle: U-shaped plate 101 supports horizontal plate 102, horizontal plate 102 supports square plate 103. The U-shaped frame 1 is installed above the chemical plant gate. The servo motor 3's shaft drives the screw 4 to rotate reciprocally. The sleeve 6 is restricted by the T-shaped guide rail 2. The inner thread tube 5 moves left and right on the threaded groove of the screw 4, driving the sleeve 6 to move left and right. The sleeve 6 slides left and right on the T-shaped guide rail 2. The inner thread tube 5 drives the square platform 7 to move left and right, which in turn drives the gear 8 to move left and right. The long strip plate 9 supports the rack 10. When wheel 8 moves to the left, it rotates clockwise on the platform 7 under the constraint of the tooth gaps of rack 10. Conversely, when gear 8 moves to the right, it rotates counterclockwise on the platform 7. Gear 8 drives camera 11 to rotate clockwise and counterclockwise, and camera 11 drives guard plate 12 to rotate clockwise and counterclockwise. Guard plate 12 is used to block backlight above camera 11. During the rotation, camera 11 identifies the faces and movements of people in specific areas through the face recognition module built into camera 11, and identifies and locates people in the chemical plant area, providing real-time perception and early warning.

[0081] The square platform 7 drives the loop frame 131 to move back and forth left and right. The loop frame 131 drives the connecting plate 132 to move back and forth left and right. The connecting plate 132 drives the ring 133 to move back and forth left and right. The ring 133 drives the sponge ring 134 to move back and forth left and right. The sponge ring 134 wipes the lubricating oil on the surface of the screw 4.

[0082] The ring 133 drives the ring frame 135 to move back and forth, the ring frame 135 slides back and forth on the straight rod 136, and the ring piece 137 limits the ring frame 135.

[0083] The ring frame 135 drives the bending frame 141 to move back and forth left and right. The bending frame 141 drives the support frame 142 to move back and forth left and right. The support frame 142 drives the groove arc frame 143 to move back and forth left and right. The camera 11 drives the round block 144 to rotate back and forth left and right. The round block 144 rotates in the groove arc frame 143. The groove arc frame 143 supports the area below the camera 11.

[0084] The bending frame 141 drives the platform rod 145 to move back and forth, and the bending frame 141 drives the reciprocating frame 146 to move back and forth. The compressed spring 147 supports the bottom of the reciprocating frame 146. Under the elastic force of the compressed spring 147, the stability of the bending frame 141 when it is supported is improved.
