Description

Technical Field

[0001] This invention relates to the field of security monitoring, and more particularly to an Internet of Things (IoT) security access control and monitoring device. Background Technology

[0002] In IoT security systems, access control and monitoring devices serve as core equipment for entrance and exit security management. The clarity of the lenses in their surveillance cameras directly affects image acquisition quality and recognition accuracy. However, access control and monitoring devices are mostly installed outdoors or at entrances and exits with high pedestrian traffic, and are exposed to complex environments such as dust, rain, and grease for extended periods. Dirt easily accumulates on the lens surface, and if not cleaned promptly, it can lead to blurred monitoring images, increased recognition errors, and even security alert failures, seriously threatening entrance and exit security. Therefore, regularly cleaning the camera lenses is a crucial step in ensuring the stable operation of access control and monitoring devices.

[0003] Currently, the main cleaning methods for access control surveillance cameras are manual cleaning or simple automatic cleaning. However, manual cleaning is cumbersome and carries relatively high safety risks. Since access control surveillance devices are often installed at high places, manual cleaning requires the use of ladders, scaffolding, and other tools to climb, which not only increases the difficulty of cleaning but also poses a risk of personnel falling. In addition, manual cleaning depends on the operator's standard operating procedures. If the cleaning solution is sprayed unevenly or the wiping force is too great, water stains and scratches can be left on the lens surface, which reduces the clarity of the monitoring. Moreover, each cleaning takes a long time, making it difficult to meet the batch maintenance needs of large-scale access control surveillance systems.

[0004] Other simple automatic cleaning devices simply use nozzles to spray liquid for rinsing. The cleaning liquid sprayed during the cleaning process can easily flow freely. If it splashes onto walls, floors, or access control equipment, it will directly cause environmental pollution and equipment damage. The sprayed cleaning liquid will also need to be cleaned up afterward, increasing the workload of maintenance.

[0005] Therefore, it is necessary to provide a new IoT security access control and monitoring device to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with related technologies, the IoT security access control and monitoring device provided by this invention has the following advantages: 1. This invention uses a main motor to drive the sealing shell to automatically slide and combine for sealing. In the second half of the sealing process, the pressure rod is pushed to compress the air pipe, causing the embedded airbag strip to inflate and expand, tightly filling the gap between the sealing shell and the through-hole. This combination sealing structure, combined with the airbag seal, can effectively prevent the liquid from spraying out from the gap between the through-hole and the sealing shell when the cleaning liquid is sprayed during the cleaning stage, avoiding the cleaning liquid from splashing onto the access control equipment, walls or the ground and causing pollution. At the same time, the cleaning process is confined to the closed space inside the main shell, ensuring that the cleaning liquid is accurately applied to the camera lens, improving the standardization of the cleaning operation and the cleanliness of the environment, and reducing the amount of cleaning liquid removal work afterwards. 2. This invention drives the drive shaft to rotate through the output end of a small motor. With the coordinated transmission of the rack and pinion and the main gear, the monitoring camera can be automatically rotated and retracted to the internal cleaning area of ​​the main housing. There is no need to manually adjust the camera angle. It can automatically and quickly make the camera appear to be ready for cleaning. It is especially suitable for access control monitoring scenarios installed at high places. At the same time, it greatly reduces the difficulty of cleaning operations and the safety risks of manual maintenance. 3. This invention uses an external motor to drive the synchronous shaft to rotate, which in turn drives the synchronous plate to move the slide bars of the two liquid exchange tubes alternately. This creates alternating negative pressure in the two liquid exchange tubes, allowing for the alternating intake and discharge of cleaning liquid. This ensures that the annular spray nozzle can continuously receive a supply of cleaning liquid. At the same time, the equidistant nozzles of the annular spray nozzle can evenly spray the cleaning liquid onto the surface of the camera lens, eliminating cleaning dead corners and providing more comprehensive cleaning coverage. This effectively avoids localized dirt residue on the lens and ensures the cleaning effect. 4. This invention uses the meshing transmission between the small gear and the large gear to drive the rotating shaft to drive the sponge brush to rotate synchronously, wiping the lens in real time after spraying liquid, forming an integrated cleaning process of spraying and wiping. It can automatically rotate and wipe the lens at the same time as rinsing, which can further improve cleaning efficiency and ensure better cleaning results each time. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 8 An IoT security access control monitoring device includes: a main housing 1, a rear seat 11 on the rear side of the main housing 1, mounting ears 12 fixedly connected to the rear seat 11, a side shell 13 on the upper side wall of the main housing 1, a through opening on the side wall of the main housing 1, a monitoring camera 2 at the through opening, two pins 21 symmetrically provided at one end of the monitoring camera 2, both pins 21 being rotatably connected to the upper inner wall of the main housing 1; and an automatic closing mechanism, the automatic closing mechanism including a sealing shell. 3. The upper end of the cover 3 is slidably connected to the upper end of the main shell 1. The rear side of the cover 3 is provided with a protrusion 31. The lower outer wall of the main shell 1 is fixedly connected with a side beam frame 32. The side beam frame 32 is fixedly connected with a vertical rod 33. The protrusion 31 and the vertical rod 33 are slidably connected. The side beam frame 32 is rotatably connected with a control shaft 34. The lower end of the side beam frame 32 is installed and connected with a main motor 35. The output end of the main motor 35 is fixedly connected to the control shaft 34. The lower end of the side beam frame 32 is provided with a pressing component.

[0021] In the specific implementation process, such as Figure 3 and Figure 5 As shown, the pressurization assembly includes a pneumatic pipe 4, which is fixedly connected to the lower end of the side beam frame 32. The lower end of the pneumatic pipe 4 is provided with a double-outlet connector 41. Both sides of the through-hole are provided with embedding grooves. An embedded airbag strip 42 is installed and connected in each of the two embedding grooves. The double-outlet connector 41 is connected to the two embedded airbag strips 42 respectively through two connecting thin tubes. A pressure rod 43 is slidably connected to the upper end of the pneumatic pipe 4. A pressure plate 44 is fixedly connected to the top of the pressure rod 43. A main piston 45 is fixedly connected to the lower end of the pressure rod 43. A return spring 46 is sleeved on the pressure rod 43.

[0022] It should be noted that: the output end of the main motor 35 drives the control shaft 34 on the side beam 32 to rotate. Since the protrusion 31 on the rear side of the cover 3 is threadedly connected to the control shaft 34, and the protrusion 31 is slidably engaged with the vertical rod 33, the protrusion 31 drives the cover 3 to slide along the upper end of the main cover 1, gradually covering the through opening, so as to complete the locking between the main cover 1 and the cover 3. In the latter half of the rising stroke of the boss 31, the lower surface of the boss 31 contacts the pressure plate 44 and pushes it. The pressure plate 44 drives the pressure rod 43 to slide along the pipe wall of the air pressure pipe 4, causing the main piston 45 at the lower end of the pressure rod 43 to move down in the air pressure pipe 4. The gas in the compressed air pressure pipe 4 is transported through the double outlet joint 41 and the connecting thin tube to the embedded airbag strips 42 embedded in the grooves on both sides of the through-hole. After the embedded airbag strips 42 are inflated, they fit tightly against the inner wall of the sealing shell 3 and the edge of the through-hole, thereby filling the sealed gap and further improving the sealing effect.

[0023] refer to Figure 5 and Figure 6 As shown, the main piston 45 is located inside the air pressure pipe 4, the pressure plate 44 is located below the boss 31, one end of the return spring 46 is connected to the pressure plate 44, and the other end of the return spring 46 is connected to the pipe wall of the air pressure pipe 4.

[0024] It should be noted that the outer wall of the main piston 45 is in close contact with the inner wall of the air pressure pipe 4; The return spring 46 can quickly push the pressure plate 44 and the pressure rod 43 to reset after the convex seat 31 is reset and moved upward, so that the embedded airbag strip 42 is deflated and contracted.

[0025] refer to Figure 5 As shown, the control shaft 34 is a threaded rod, and the boss 31 is provided with a threaded opening. The boss 31 is threadedly connected to the control shaft 34.

[0026] refer to Figure 3 and Figure 4 As shown, one end of the pin 21 extends to the outside of the main shell 1, and a main gear 5 is fixedly connected to the pin 21. A rack 51 is provided on the rear side of the main gear 5. The rack 51 meshes with the main gear 5. A hidden frame 52 is fixedly connected to the inner wall of the side shell 13. A limit rod 53 is fixedly connected to the hidden frame 52. A cross block is provided on the rear side of the rack 51. The cross block is slidably connected to the limit rod 53. A drive shaft 54 ​​is rotatably connected in the hidden frame 52. A small motor 55 is installed and connected at the lower end of the hidden frame 52. The output end of the small motor 55 is fixedly connected to the drive shaft 54.

[0027] It should be noted that: the output end of the small motor 55 drives the drive shaft 54 ​​on the hidden frame 52 to rotate, and the horizontal block connected to the drive shaft 54 ​​slides along the limit rod 53. The horizontal block drives the rack 51 to move, and the rack 51 meshes with the main gear 5 on the pin 21. The movement of the rack 51 drives the main gear 5 to rotate, which in turn drives the pin 21 to rotate synchronously with the monitoring camera 2, so that the lens of the monitoring camera 2 faces the cleaning area inside the main shell 1 (above the bottom plate 6), completing the automatic rotation and retraction, and preparing for subsequent cleaning.

[0028] refer to Figure 4 As shown, the drive shaft 54 ​​is a threaded rod, and the cross block has a threaded opening, and the cross block is threadedly connected to the drive shaft 54.

[0029] refer to Figure 3 and Figure 7 As shown, a bottom plate 6 is fixedly connected to the lower end of the main shell 1, a cylinder seat 61 is fixedly connected to the middle of the bottom plate 6, a rotating shaft 62 is rotatably connected to the cylinder seat 61, a sponge brush strip 63 is installed and connected to the top of the rotating shaft 62, an annular spray nozzle 64 is fixedly connected to the cylinder seat 61, the annular spray nozzle 64 is provided with multiple nozzles, the multiple nozzles are arranged in an equidistant ring, a water inlet pipe 65 is provided on one side of the annular spray nozzle 64, and two arc-shaped flow outlets are symmetrically provided on the bottom plate 6.

[0030] It should be noted that the soft surface of the sponge brush strip 63 can effectively wipe away stains on the lens surface while avoiding scratching the lens coating; The nozzle of the annular spray nozzle 64 is oriented at a 45° angle to the lens surface. This design allows the cleaning liquid to be sprayed evenly onto the lens surface in a mist form, avoiding direct impact of the liquid on the lens and causing the stains to spread. At the same time, the equally spaced annular nozzles ensure that there are no dead angles in the spray. The lowest point of the arc-shaped outlet is lower than other areas of the bottom plate 6, which facilitates the rapid collection and discharge of sewage and prevents sewage from accumulating on the bottom plate 6.

[0031] refer to Figure 7 and Figure 8As shown, an external bracket 7 is fixedly connected to the lower end of the main shell 1. A synchronous shaft 71 is rotatably connected to the external bracket 7. A small gear 72 is fixedly connected to the lower end of the synchronous shaft 71. A large gear 73 is fixedly connected to the lower end of the rotating shaft 62. The large gear 73 and the small gear 72 mesh with each other. Right-angle brackets 74 are fixedly connected to both ends of the external bracket 7. Fluid changing pipes 8 are installed on both right-angle brackets 74. A sliding rod 81 is slidably connected to one end of the pipe wall of each of the two fluid changing pipes 8. An internal piston 82 is fixedly connected to one end of each of the two sliding rods 81. A three-way pipe 83 is provided on the other end of the pipe wall of each of the two fluid changing pipes 8. An inlet valve 84 is installed in the main pipe of the three-way pipe 83. A drain valve 85 is installed in the branch pipe of the three-way pipe 83. The branch pipes of the two three-way pipes 83 are connected to the water inlet pipe 65 through a delivery pipe. A synchronous plate 9 is fixedly connected between the two sliding rods 81.

[0032] It should be noted that the transmission between the small gear 72 and the large gear 73 enables the rotating shaft 62 to rotate stably, ensuring that the sponge brush strip 63 rotates synchronously. This not only allows for thorough wiping of the lens but also prevents the cleaning liquid from splashing due to excessive rotation speed. The built-in piston 82 inside the fluid exchange tube 8 fits tightly against the tube wall, ensuring stable negative pressure inside the fluid exchange tube 8 and enabling smooth pumping of cleaning liquid.

[0033] refer to Figure 7 As shown, the external bracket 7 has a strip-shaped opening, the middle position of the synchronization plate 9 is slidably connected to the strip-shaped opening, the synchronization shaft 71 is a reciprocating lead screw, the synchronization plate 9 is threadedly connected to the synchronization shaft 71, and an external motor 91 is installed and connected on the external bracket 7, the output end of the external motor 91 is fixedly connected to the synchronization shaft 71.

[0034] It should be noted that: the output end of the external motor 91 drives the synchronous shaft 71 to rotate, and the synchronous shaft 71 drives the synchronous plate 9, which is threaded to it, to slide back and forth along the strip opening of the external bracket 7. The synchronous plate 9 drives the slide rods 81 on the two liquid exchange pipes 8 to move synchronously, so that negative pressure is alternately formed in the two liquid exchange pipes 8.

[0035] The working principle of the IoT security access control monitoring device provided by this invention is as follows: When it is necessary to clean the protective lens of the monitoring camera 2, the small motor 55 inside the side shell 13 is started, so that the output end of the small motor 55 drives the drive shaft 54 ​​on the hidden frame 52 to rotate. The horizontal block threadedly connected to the drive shaft 54 ​​slides along the limit rod 53. The horizontal block drives the rack 51 to translate. The rack 51 meshes with the main gear 5 on the pin 21. The movement of the rack 51 drives the main gear 5 to rotate, thereby driving the pin 21 and the monitoring camera 2 to rotate synchronously, so that the lens of the monitoring camera 2 faces the cleaning area inside the main shell 1 (above the bottom plate 6), completing the automatic rotation and retraction, and preparing for subsequent cleaning.

[0036] Start the main motor 35. The output end of the main motor 35 drives the control shaft 34 on the side beam 32 to rotate. Since the boss 31 on the rear side of the cover 3 is threadedly connected to the control shaft 34 and the boss 31 is slidably engaged with the vertical rod 33, the boss 31 drives the cover 3 to slide along the upper end of the main cover 1, gradually covering the through opening, so as to complete the locking between the main cover 1 and the cover 3.

[0037] In the latter half of the rising stroke of the boss 31, the lower surface of the boss 31 contacts the pressure plate 44 and pushes it. The pressure plate 44 drives the pressure rod 43 to slide along the pipe wall of the air pressure pipe 4, causing the main piston 45 at the lower end of the pressure rod 43 to move down in the air pressure pipe 4. The gas in the compressed air pressure pipe 4 is transported through the double outlet joint 41 and the connecting thin tube to the embedded airbag strips 42 embedded in the grooves on both sides of the through-hole. After the embedded airbag strips 42 are inflated, they fit tightly against the inner wall of the sealing shell 3 and the edge of the through-hole, thereby filling the sealed gap and further improving the sealing effect.

[0038] After the sealing is completed, the cleaning stage begins. The external motor 91 on the external bracket 7 is started. The output end of the external motor 91 drives the synchronous shaft 71 to rotate. The synchronous shaft 71 drives the synchronous plate 9, which is threaded to it, to slide back and forth along the strip-shaped opening of the external bracket 7. The synchronous plate 9 drives the slide rods 81 on the two liquid exchange pipes 8 to move synchronously, so that negative pressure is alternately formed in the two liquid exchange pipes 8. The cleaning liquid alternately flows in through the inlet valve 84 in the two three-way pipes 83 and is discharged through the outlet valve 85, and is pumped to the annular spray nozzle 64. The annular spray nozzle 64 can continuously pump in the cleaning liquid and spray it evenly onto the lens surface of the monitoring camera 2 through the nozzle to complete the automatic cleaning.

[0039] The small gear 72 at the lower end of the synchronous shaft 71 meshes with the large gear 73 at the lower end of the rotating shaft 62. The rotation of the synchronous shaft 71 drives the large gear 73 to rotate synchronously with the rotating shaft 62. The sponge brush 63 at the top of the rotating shaft 62 rotates accordingly to wipe and clean the lens surface that has been sprayed with cleaning liquid. Wastewater is discharged through the arc-shaped outlet of the bottom plate 6.

[0040] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
