Description

Technical Field

[0001] This utility model relates to the field of video surveillance technology, specifically a video surveillance device for storing fireworks and firecrackers. Background Technology

[0002] Fireworks and firecrackers are flammable and explosive materials, and their storage conditions need to be strictly controlled to prevent accidents. Therefore, video monitoring devices are usually installed in the storage room.

[0003] Patent CN222531765U discloses a self-cleaning camera, including a dust removal device with an air pump. The air pump's air pipe is connected to a jet nozzle, the jet nozzle's jet tip facing the dustproof glass. It also includes an electric reciprocating lifting system, the lifting mechanism of which employs a screw mechanism, with the jet nozzle mounted on the slider of the screw mechanism. Furthermore, it includes an infrared beam switch, the sensor of which includes an infrared beam sensor. The control signal output of the infrared beam switch controls and connects to the air pump and the electric reciprocating lifting system. The infrared emitting element and infrared receiving element of the infrared beam sensor are located on both sides of the dustproof glass, arranged in a beam-to-beam configuration. This design allows for automatic cleaning of the camera, facilitating operation and saving manpower.

[0004] However, the aforementioned cameras still present the following problems in actual use: Fireworks and firecrackers are extremely dangerous flammable and explosive materials. If their storage warehouse unfortunately catches fire, these items will ignite rapidly in a very short time and cause a violent explosion, with potential hazards far exceeding those of ordinary fire incidents. In this situation, if the fire or explosion causes a power outage, the monitoring system's cameras will cease operation, thus losing the ability to monitor the situation inside the storage room. This not only hinders real-time situation monitoring but also affects firefighters' ability to obtain critical information to formulate effective rescue strategies, causing significant inconvenience to emergency response. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a video surveillance device for storing fireworks and firecrackers, which can provide an extra layer of protection for the camera body in the event of an emergency, thereby improving the camera body's ability to continuously monitor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a video monitoring device for storing fireworks and firecrackers, comprising a steel frame and a camera body mounted on the steel frame. A support plate is fixedly connected to the outer wall of the steel frame. A second support block and several first support blocks are fixedly connected to the upper surface of the camera body. A rotating motor is fixedly connected to the upper end of the second support block. Rotating rods are rotatably connected to the upper ends of the several first support blocks. Rotating blocks are fixedly connected to the output shaft of the rotating motor and the other ends of the several rotating rods. The several rotating blocks are evenly divided into two groups. A first explosion-proof plate and a second explosion-proof plate are fixedly connected to the two groups of rotating blocks respectively. A transmission assembly is connected between the first explosion-proof plate and the second explosion-proof plate. A monitoring mechanism is connected to the bottom surface of the first explosion-proof plate and the second explosion-proof plate. A spare battery is fixedly connected to the upper surface of the camera body.

[0007] Furthermore, both transmission components include arc-shaped bars and several teeth, with the teeth fixedly connected to the outer wall of the arc-shaped bars. The upper ends of the two arc-shaped bars are fixedly connected to the adjacent ends of the first and second explosion-proof plates, respectively, and the two sets of teeth mesh.

[0008] Furthermore, the detection mechanism includes a smoke sensor, the outer wall of which is fixedly connected to the bottom of the second explosion-proof plate.

[0009] Furthermore, the backup battery is electrically connected to both the smoke sensor and the controller inside the camera body.

[0010] Furthermore, an audible and visual alarm that is electrically connected to a backup battery is fixedly connected to the upper surface of the second explosion-proof plate.

[0011] Furthermore, explosion-proof glass is fixedly connected to the end of the first and second explosion-proof plates near the main lens of the camera, and the two pieces of explosion-proof glass are located directly in front of the main lens of the camera.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This video surveillance device for storing fireworks and firecrackers uses a rotating motor to drive the first and second explosion-proof plates to close quickly, forming a physical barrier to enclose the camera body. Combined with the double protection of explosion-proof glass, it effectively resists the shock waves and fragments generated by the explosion of fireworks and firecrackers, greatly reducing the risk of the camera being damaged in the explosion.

[0014] 2. This video surveillance device for storing fireworks and firecrackers uses smoke sensors and the camera's own infrared detection function to accurately identify fire or explosion risks and automatically trigger protection mechanisms and audible and visual alarms, thereby shortening emergency response time and reducing the risk of personal injury and property loss.

[0015] 3. This video monitoring device for storing fireworks and firecrackers uses a transmission component to extend or retract the explosion-proof plate. If a false alarm is detected or the danger is cleared, the first and second explosion-proof plates can be manually or remotely reset to restore the camera's normal monitoring function and reduce maintenance costs.

[0016] 4. This type of video surveillance device for storing fireworks and firecrackers allows the camera to continue recording even when the explosion-proof glass is in a protective state. Firefighters can understand the dynamics inside the fire scene through real-time images, formulate precise rescue plans, improve fire extinguishing efficiency, and reduce the risk of secondary explosions.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-6A video surveillance device for storing fireworks and firecrackers includes a steel frame 1 and a camera body 8 mounted on the steel frame 1. A support plate 2 is fixedly connected to the outer wall of the steel frame 1. A second support block 13 and several first support blocks 11 are fixedly connected to the upper surface of the camera body 8. A rotating motor 14 is fixedly connected to the upper end of the second support block 13. A rotating rod 12 is rotatably connected to the upper end of each of the several first support blocks 11. A rotating block 16 is fixedly connected to the output shaft of the rotating motor 14 and the other end of each of the rotating rods 12. The rotating blocks 16 are divided into two groups. A first explosion-proof plate 3 and a second explosion-proof plate 4 are fixedly connected to the two groups of rotating blocks 16 respectively. A transmission assembly is connected between the first explosion-proof plate 3 and the second explosion-proof plate 4. A monitoring mechanism is connected to the bottom surface of the first explosion-proof plate 3 and the second explosion-proof plate 4. A spare battery 10 is fixedly connected to the upper surface of the camera body 8.

[0026] like Figures 1 to 6 As shown, in the video surveillance device for storing fireworks and firecrackers of this utility model, the lens of the camera body 8 will always monitor the storage room. During the monitoring process, the monitoring mechanism will monitor the smoke and temperature in the storage room in real time. If a fire breaks out in the storage room, smoke will rise rapidly, and it may even cause an explosion due to the fireworks and firecrackers. When the monitoring mechanism detects smoke (and can also cooperate with the infrared camera monitoring that the camera body 8 itself has, such as a flame or smoke rising from a certain place), the controller (or external controller) of the camera body 8 will immediately start the rotating motor 14. After the rotating motor 14 starts, the output shaft will rotate together with several rotating rods 12 and several rotating blocks 16. Thus, the first explosion-proof plate 3 and the second explosion-proof plate 4 can be rotated down from both sides of the camera body 8 through the two sets of rotating blocks 16, thereby covering the camera body 8. At this time, due to the temporary power supply of the backup battery 10, the previously recorded data can be uploaded to the cloud wirelessly in a timely manner.

[0027] It is important to note that by setting up a backup battery 10, it can be kept fully charged during normal use because it is connected to the external main power supply. In the event of a fire, especially if the fire is large and the external power supply is actively or passively cut off, the backup battery 10 can provide temporary power to the rotating motor 14 and the camera body 8. This provides protection for the camera body 8 and allows time to upload monitoring data from the camera body 8 to the cloud and continue monitoring. In addition, heat insulation material is installed on the inner walls of the first explosion-proof plate 3 and the second explosion-proof plate 4 to further reduce the damage rate of the camera body 8 located inside the first explosion-proof plate 3 and the second explosion-proof plate 4 due to the high external temperature.

[0028] Please refer to the following: Figures 1-6Both transmission components include an arc-shaped strip 9 and several teeth 15. The teeth 15 are fixedly connected to the outer wall of the arc-shaped strip 9. The upper ends of the two arc-shaped strips 9 are fixedly connected to the adjacent ends of the first explosion-proof plate 3 and the second explosion-proof plate 4, respectively. The two sets of teeth 15 mesh.

[0029] More specifically, when the rotating motor 14 is started, the output shaft of the rotating motor 14 will rotate together with the second explosion-proof plate 4. Then, the arc-shaped strip 9 installed on the second explosion-proof plate 4 will rotate together with a number of teeth 15. As this set of teeth 15 on the second explosion-proof plate 4 rotates, it will mesh and rotate together with the first explosion-proof plate 3. Since the teeth 15 mesh and rotate in opposite directions, it is possible to control the first explosion-proof plate 3 and the second explosion-proof plate 4 to fold and store in the middle or unfold to the sides at the same time.

[0030] Please refer to the following: Figures 1-6 The detection mechanism includes a smoke sensor 7, the outer wall of which is fixedly connected to the bottom of the second explosion-proof plate 4.

[0031] More specifically, during daily use, the smoke sensor 7 will work with the camera function built into the camera body 8 to monitor the fireworks storage room. If the smoke sensor 7 detects an abnormality in the storage room, it will quickly send the abnormal signal to the internal processor of the camera body 8 or the external main processor. Then, the controller will immediately start the rotating motor 14 and simultaneously upload the previous monitoring data to the cloud for later retrieval.

[0032] It should be noted that if the smoke sensor 7 is falsely alarming and no abnormality has occurred, the administrator can restart the rotating motor 14 through the main controller to control the first explosion-proof plate 3 and the second explosion-proof plate 4 to unfold again, and then continue the subsequent monitoring.

[0033] Please refer to the following: Figures 1-6 The backup battery 10 is electrically connected to the smoke sensor 7 and the internal controller of the camera body 8. An audible and visual alarm 5, electrically connected to the backup battery 10, is fixedly connected to the upper surface of the second explosion-proof plate 4.

[0034] More specifically, by setting up the audible and visual alarm 5, an alarm can be sounded in time when the smoke sensor 7 detects an abnormal situation, reminding staff to evacuate immediately.

[0035] Please refer to the following: Figures 1-6 The first explosion-proof plate 3 and the second explosion-proof plate 4 are both fixedly connected to the end of the camera body 8 lens with explosion-proof glass 6. The two explosion-proof glass 6 are located in front of the camera body 8 lens.

[0036] More specifically, by installing explosion-proof glass 6, the camera body 8 can continue to be powered by the backup battery 10 while the first explosion-proof plate 3 and the second explosion-proof plate 4 are protecting it. The camera body 8 can continue to monitor the situation inside the storage room. Firefighters can understand the dynamics inside the fire scene through real-time images, formulate precise rescue plans, improve fire extinguishing efficiency, and reduce the risk of secondary explosions.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
