Description

Technical Field

[0001] The present invention relates to the technical field of fire monitoring, and in particular to a fire early warning monitoring system. Background Art

[0002] Fire protection engineering construction is usually equipped with real-time monitoring to monitor the fire protection engineering, and timely warning is given through monitoring when a fire occurs to avoid greater losses in the fire protection engineering construction area. However, the current real-time monitoring system of fire protection engineering is difficult to quickly adjust the angle of the monitoring structure during deployment, and it is difficult to issue a timely warning when a fire is discovered so that the staff in the nearby area can be informed of the warning information in time. Patent documents have now been issued to improve this.

[0003] For example, Chinese patent CN115662051A, a real-time monitoring system with fire warning function based on fire engineering construction, relates to the technical field of monitoring system. The real-time monitoring system aims to solve the technical problems that the real-time monitoring system of fire engineering in the prior art is difficult to quickly adjust the angle of the monitoring structure during deployment, and difficult to issue a timely warning when a fire is discovered so that the staff in the nearby area can timely obtain the warning information. The real-time monitoring system includes a monitoring box, an early warning box fixedly installed on the right end of the monitoring box, and a first fixed box fixedly installed on the left end of the monitoring box; a fixed frame is fixedly installed on the rear end of the monitoring box, a first storage battery is fixedly installed on the inner wall of the fixed frame, and a support block is fixedly installed on the upper end of the fixed frame. The real-time monitoring system can quickly adjust the angle of the monitoring structure during deployment, and can issue a timely warning when a fire is discovered so that the staff in the nearby area can timely obtain the warning information.

[0004] Although the design in the above document can observe the fire situation through the camera and use the wireless transceiver for early warning, it still has obvious defects in actual use, such as: The device in the document installs the camera and the fire detector on the same side, which results in a relatively fixed monitoring range.

Beneficial Effects

[0014] The present invention provides a fire early warning monitoring system. Compared with the existing technology, it has the following beneficial effects: (1) The fire warning monitoring system uses a warning cleaning mechanism and a monitoring driving mechanism in combination. The arrangement of the two mechanisms can utilize the drive of the motor to drive the vertical rotating column and the fire detectors and cameras at the bottom and top thereof to rotate to increase the monitoring range. The linkage of the first push rod and the second push rod can enable the fire detector and the camera to reciprocate, allowing the motor to rotate in the same direction without the need for reverse starting, avoiding frequent starting and reducing the power consumption during starting. During rotation, the linkage between the structures can also be utilized to push the first ring wiping frame and the second ring wiping frame to wipe the fire detector and the camera, thereby effectively improving the overall practicality of the equipment.

The arrangement of these structures can ensure that when the motor is rotating in one direction, the vertical rotating column can still rotate forward and reverse, which can not only improve the monitoring range, but also ensure the overall connectivity of the equipment.

[0016] (3) The fire early warning monitoring system is used in conjunction with a diamond arc block by installing a first ring wiping frame and a second ring wiping frame on the top and bottom of the protection box respectively using lifting rods. The arrangement of these structures can squeeze the round head block when the diamond arc block rotates with the circular turntable, so that the first ring wiping frame and the second ring wiping frame can be lifted and lowered respectively to wipe the fire detector and the camera, thereby ensuring the sensitivity of the fire detector and the clarity of the camera.

[0017] (4) The fire warning monitoring system sets the orientation of several fire detectors and cameras to the same position, so that the fire detectors can stop after detecting a fire, and the cameras below can follow the fire detectors to face the direction of the fire, ensuring that the staff can quickly find the fire location and observe the fire situation.

The upper and lower parts of the surface of the lifting rod 107 are fixedly connected with a back-stop ring plate 111. The surface of the lifting rod 107 and the inner side of the protective box 101 are sleeved with a first spring 112. The end of the lifting rod 107 located inside the protective box 101 is fixedly connected with a round head block 110. The front and rear parts of the inner cavity of the protective box 101 are fixedly connected with an arc top block 113 through a bracket. The two arc top blocks 113 are opposite and staggered up and down. The protective box 101 is arranged to be close to but not in contact with the circular turntable 204. Both sides of the rear of the protective box 101 are fixedly connected with an assembly bracket 114 through a fixing plate. Both sides of the top of the protective box 101 are fixedly connected with an alarm 115 through a fixing plate.

[0025] When the circular rotating disk 204 rotates counterclockwise, the first stopper 205 and the first push rod 212 will rotate relative to each other. When the vertical rotating column 201 rotates counterclockwise by 180 degrees, the arc top block 113 at the lower part will be inserted between the second push rod 216 and the circular rotating disk 204, and squeeze the second push rod 216 to make the second push rod 216 descend under the limiting effect of the second guide rod 214.

After the diamond arc block 218 is separated from the round head block 110, the lifting rod 107 will drive the reset under the elastic force of the first spring 112. When one of the fire detectors 202 detects a fire, the fire detector 202 will send data to the single-chip microcomputer 116. After receiving the data, the single-chip microcomputer 116 will stop the motor 102 and the corresponding motor 102 and camera 203 will face the direction of the fire, and start the alarm 115 for early warning. At the same time, the single-chip microcomputer 116 will use the wireless transceiver 117 to send the fire information to the staff. The staff will control the camera 203 through the wireless transceiver 117 to quickly observe the location and situation of the fire, and restart the motor 102 using the wireless transceiver 117 later.
