[0002] Security monitoring equipment can reflect the monitored object in real time, vividly and truly, and can greatly increase the observation distance and observation function of the human eye, and can adapt to various harsh environments. The remote security monitoring system uses digital network as the transmission medium and network video server as the core. It comprehensively uses digital video processing technology, automatic control, network transmission technology and artificial intelligence technology. It not only has the advantages of ordinary security monitoring systems such as fast video processing capabilities, digital information anti-interference capabilities, and easy to quickly query records, but also relies on the network to give full play to the advantages brought by broadband networks. Through IP networks, the monitoring video center and any point that can be connected to the network are interconnected to achieve the ideal remote, centralized and real-time effects of closed-circuit monitoring systems.

[0003] However, the existing security monitoring equipment still has certain defects when in use;

[0004] For example, an intelligent building security monitoring device proposed in application number CN202211284119.7 specifically relates to the field of electronic technology, including a storage box, a fire protection mechanism assembly is provided at the bottom of the storage box, and a heat transfer tube is provided on the inner wall of the fire protection mechanism assembly, a protective shell is connected through the outer wall of the heat transfer tube, an air plate is fixedly connected to the other end of the No. 2 transmission line, a No. 3 transmission line is fixedly connected to the inner wall of the connector, and a protective structure assembly is fixedly connected to one side of the storage box. The present invention protects the storage box by providing a fire protection mechanism assembly and a protective structure assembly, thereby preventing damage to the camera in the event of a fire, improving the safety of the camera, ensuring the quality of the subsequent use of the camera, and increasing the service life of the overall device. At the same time, it can alert internal personnel in the first time, ensuring the efficiency of the subsequent evacuation of personnel, and increasing the practicality of the overall device. In actual use, the following problems still exist:

[0005] 1. When the intelligent building security monitoring device monitors the fire scene, although it is equipped with fire prevention mechanism components and protective structure components to improve safety performance, and improves evacuation efficiency by warning internal personnel, a large amount of smoke and dust will be generated at the fire scene, which will cause the monitoring of the security monitoring equipment to be blocked by the smoke and dust, affecting the monitoring effect and reducing practicality;

[0006] 2. The intelligent security monitoring device of the building uses an alarm to warn and assist in evacuation of internal personnel at the fire scene. However, the fire scene is chaotic and the warning light emitted by the alarm is easily blocked by smoke and dust, which affects the penetration effect of the warning light, thereby reducing the warning effect.

[0007] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0023] Preferably, the upper atomizing nozzle is symmetrically installed on the top of the monitoring module, and the water outlet end of the lower atomizing nozzle is distributed parallel to the front side of the drainage warning plate.

[0024] The above-mentioned technical scheme is adopted to facilitate the atomizing smoke removal mechanism to extract water from the external fire-fighting pipe and spray it out in an atomized manner during the reciprocating piston movement, so that the atomized water can effectively eliminate the smoke and dust at the front end of the monitoring module and the evacuation warning plate, avoid obstructing the monitoring field of view of the monitoring module and affecting the warning clarity of the evacuation warning plate, thereby improving the practicality and use effect of the security monitoring equipment that can assist in guiding evacuation.

[0027] The adoption of the above technical scheme makes it easy to utilize the characteristic that the one-way transmission mechanism can only transmit in one direction, so that the heat dissipation and smoke elimination and dust reduction processes can be switched in scenarios where a fire occurs and where no fire occurs. This is beneficial for effective heat dissipation when there is no fire, and is also beneficial for smoke elimination and dust reduction when a fire occurs, thereby improving the structural linkage and convenience of the working state switching operation of the security monitoring equipment that can assist in guiding evacuation.

[0034] 1. The ventilation and heat dissipation mechanism can extract the heat generated inside the protective outer shell when rotating in the forward direction, so as to achieve rapid heat dissipation of the monitoring module inside the protective outer shell, which is beneficial to prevent the monitoring module from being damaged by heat accumulation during operation, and improves the heat dissipation effect of the security monitoring equipment that can assist in guiding evacuation;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-10The present invention provides a technical solution: a security monitoring device that can assist in guiding evacuation, comprising a protective outer shell 1, a monitoring module 2 is fixedly installed inside the front end of the protective outer shell 1, a connecting line 3 for information transmission is installed on the top of the monitoring module 2, and the connecting line 3 is connected to the top of the protective outer shell 1; a evacuation warning plate 7 is fixedly installed on the bottom of the protective outer shell 1, a connecting seat 4 is symmetrically installed on the top of the protective outer shell 1, a supporting frame 5 is sleeved on the outer side of the connecting seat 4, and a mounting plate 6 is fixedly installed on the top of the supporting frame 5, and the mounting plate 6 can be fixedly connected to the building with expansion bolts;

[0050] The design of the above structure allows the expansion bolts to pass through the mounting plate 6 and to be fixedly connected to the wall of the building, thereby facilitating the positioning and installation of the mounting plate 6. The setting of the support frame 5 and the connecting seat 4 can support the protective outer shell 1 and the monitoring module 2 and related firmware at the bottom, thereby realizing the stable and convenient installation of the security monitoring equipment that can assist in guiding evacuation. The setting of the evacuation warning plate 7 can display the evacuation information, thereby facilitating the evacuation and guiding of internal personnel when a fire occurs, thereby improving the use effect.

[0051] The rear end of the protective outer shell 1 is fixedly connected with a ventilation and heat dissipation mechanism, which includes a positioning frame 8 fixedly installed on the rear end of the protective outer shell 1, a filter plate 9 fixedly installed on the inner side of the positioning frame 8, a servo motor 10 is inlaid and installed in the center of the filter plate 9, and a heat dissipation fan blade 11 is fixedly connected to the front end of the servo motor 10, the outer ring of the heat dissipation fan blade 11 is fixedly connected to the inner ring of the transmission gear ring 12, and the heat dissipation fan blade 11 is distributed at equal angles between the transmission gear ring 12 and the shaft end of the servo motor 10;

[0052] The design of the above structure enables the control servo motor 10 to drive the heat dissipation fan blades 11 to rotate forward and reverse, wherein an air duct for air circulation is present at the connection between the positioning seat 24 and the protective outer shell 1 and the monitoring module 2, which is beneficial for the heat dissipation fan blades 11 to generate an airflow from front to back during forward rotation, thereby facilitating the rapid dissipation of heat generated by the monitoring module 2 inside the protective outer shell 1 to achieve efficient heat dissipation, and the heat dissipation fan blades 11 can generate an airflow from back to front during reverse rotation, so that the airflow can pneumatically eliminate the smoke and dust at the front end of the monitoring module 2, thereby improving the heat dissipation and smoke and dust elimination effects.

[0053] A transmission gear ring 12 is fixedly installed at the front end of the ventilation and heat dissipation mechanism, and a one-way transmission mechanism is installed at the rear end of the atomization and smoke removal mechanism. The one-way transmission mechanism is connected to the transmission gear ring 12 in transmission. The one-way transmission mechanism includes a connecting bearing 25 symmetrically installed at the rear end of the reciprocating screw 16, and the outer ring of the connecting bearing 25 is fixedly connected to a driven gear 26. The reciprocating screw 16 is rotatably connected to the driven gear 26 through the connecting bearing 25. The driven gear 26 is meshed with the transmission gear ring 12. An inner transmission seat 27 is fixedly installed on the inner side of the driven gear 26. The inner ring of the inner transmission seat 27 is provided with a ratchet groove 28. The one-way transmission mechanism also includes a fixed sleeve located at the driven gear. The fixed ring seat 29 of the outer ring of the reciprocating screw rod 16 inside the gear 26, the outer ring of the fixed ring seat 29 is symmetrically provided with a receiving groove 30, the inner side of the receiving groove 30 is fixedly installed with a fixing rod 31, the outer ring of the fixing rod 31 is rotatably sleeved with a ratchet body 32, the ratchet bodies 32 are symmetrically distributed on the fixing rod 31, the side of the ratchet body 32 close to the receiving groove 30 and the wall surface of the receiving groove 30 are fixedly installed with a limiting seat 33, a reset spring 34 is fixedly sleeved on the limiting seat 33, the ratchet body 32 and the receiving groove 30 form a telescopic reset structure through the limiting seat 33 and the reset spring 34, and the ratchet body 32 is movably engaged with the ratchet groove 28;

[0054] The design of the above structure enables the heat dissipation fan blade 11 to drive the transmission gear ring 12 to rotate when rotating, and then the transmission gear ring 12 will drive the driven gear 26 to rotate at the rear end of the reciprocating screw 16 by meshing with the driven gear 26, and then the connecting bearing 25 will also drive the inner transmission seat 27 and the ratchet groove 28 to rotate;

[0055] When the heat dissipation fan blade 11 and the transmission gear ring 12 rotate in the forward direction, the rotation of the ratchet groove 28 will squeeze the ratchet body 32, so that the ratchet body 32 cooperates with the limit seat 33 to push the return spring 34 to be compressed, and then the ratchet body 32 cooperates with the fixing rod 31 inside the accommodating groove 30 to shrink. At this time, the rotation of the driven gear 26, the inner transmission seat 27 and the ratchet groove 28 will not drive the fixing ring seat 29 and the reciprocating screw 16 to rotate;

[0056] When the cooling fan blades 11 and the transmission gear ring 12 rotate in opposite directions, the reset spring 34 cooperates with the limit seat 33 to elastically reset the ratchet body 32, so that the ratchet body 32 and the ratchet groove 28 are in an engaged state. At this time, the rotation of the driven gear 26, the internal transmission seat 27 and the ratchet groove 28 will cooperate with the ratchet body 32 to drive the fixed rod 31, the accommodating groove 30, the fixed ring seat 29 and the reciprocating screw 16 to rotate, thereby realizing the driving of the atomization and smoke removal mechanism.

[0057] The left and right sides of the protective outer shell 1 are inlaid with atomizing smoke removal mechanisms, which include piston shells 13 inlaid inside the left and right sides of the protective outer shell 1, a vent 14 is provided on the outer side of the rear end of the piston shell 13, and a positioning bearing 15 is inlaid in the middle of the front end of the piston shell 13. The inner ring of the positioning bearing 15 is fixedly connected with a reciprocating screw 16, and the outer ring of the reciprocating screw 16 located inside the piston shell 13 is sleeved with a piston pressure plate 17. When the reciprocating screw 16 rotates, it drives the piston pressure plate 17 to slide back and forth inside the piston shell 13. The atomizing smoke removal mechanism also includes a one-way water inlet valve 18 fixedly inlaid at the bottom of the front end of the piston shell 13. The front end of the one-way water inlet valve 18 is fixedly connected with a connecting pipe 19, and the top end of the connecting pipe 19 can be connected to the fire-fighting pipe. A one-way water outlet valve 20 is inlaid and installed on the top of the front end of the piston housing 13. The front end of the one-way water outlet valve 20 is fixedly connected with a diverter pipe 21. The water outlet ends of the diverter pipe 21 are respectively connected with an upper atomizing nozzle 22 and a lower atomizing nozzle 23. The upper atomizing nozzle 22 is symmetrically installed on the top of the monitoring module 2, and the water outlet end of the lower atomizing nozzle 23 is parallel to the front side of the drainage warning plate 7. The outer sides of the upper atomizing nozzle 22 and the lower atomizing nozzle 23 are sleeved with a positioning seat 24, and the positioning seat 24 is installed at an equal angle between the protective outer shell 1 and the monitoring module 2;

[0058] The design of the above structure enables the reciprocating screw 16 to rotate smoothly in cooperation with the positioning bearing 15 at the front end inside the piston housing 13, thereby driving the piston pressure plate 17 to slide back and forth inside the piston housing 13. When the piston housing 13 moves to the rear end, it cooperates with the one-way water inlet valve 18 and the connecting pipe 19 to extract water from the external fire-fighting pipe and store it inside the piston housing 13. Then, when the piston pressure plate 17 moves to the front end, the water stored in the piston housing 13 is discharged. Atomization and spraying are performed through the one-way water outlet valve 20 and the diverter pipe 21 in cooperation with the upper atomizing nozzle 22 and the lower atomizing nozzle 23. At this time, the water atomized by the upper atomizing nozzle 22 can reduce the smoke and dust at the front end of the monitoring module 2, so that the monitoring module 2 can clearly observe the fire phenomenon, and the water atomized by the lower atomizing nozzle 23 can reduce the smoke and dust at the front end of the evacuation warning board 7, so that the contents on the evacuation warning board 7 can be clearly displayed to the personnel at the fire scene, so as to realize effective auxiliary guidance evacuation.

[0059] A method for using a security monitoring device that can assist in guiding evacuation, further comprising:

[0060] Step 1: Use expansion bolts to position the mounting plate 6 on the wall of the building, thereby realizing the installation and positioning of the security monitoring device that can assist in guiding evacuation, and then connect the connecting pipe 19 in the atomizing smoke removal mechanism to the fire protection pipeline to realize the water supply connection work;

[0061] Step 2: When the monitoring module 2 generates heat during operation, the ventilation and heat dissipation mechanism is controlled to rotate in the forward direction to quickly dissipate the heat inside the protective outer shell 1 and achieve heat dissipation. At this time, the airflow flows from front to back. At this time, the rotation of the ventilation and heat dissipation mechanism and the transmission gear ring 12 cannot cooperate with the one-way transmission mechanism to drive the atomization smoke removal mechanism to operate;

[0062] Step 3: When a fire occurs, the ventilation and heat dissipation mechanism is controlled to rotate in the opposite direction. At this time, the airflow generated by the ventilation and heat dissipation mechanism flows from the back to the front, thereby starting to evacuate the smoke and dust at the front end of the monitoring module 2;

[0063] Step 4: The reverse rotation of the ventilation and heat dissipation mechanism will cooperate with the one-way transmission mechanism to drive the atomizing smoke removal mechanism to perform piston movement, so that the atomizing smoke removal mechanism can extract water from the external fire-fighting pipe and spray it out in atomization during the piston movement, and can perform atomization to remove the smoke and dust at the front end of the monitoring module 2 and the diversion warning plate 7.
