Abstract
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 project. When a fire occurs, timely warning is issued through monitoring 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. When a fire is discovered, it is difficult to issue a timely warning so that workers in nearby areas can be informed of the warning information in a timely manner. Patent documents have now been issued to improve this.
[0003] For example, Chinese patent CN115662051A, a real-time monitoring system with a fire warning function based on fire protection engineering construction, relates to the technical field of monitoring systems. The real-time monitoring system is intended to solve the technical problems of the real-time monitoring system of fire protection engineering in the existing technology that it 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 a timely manner. 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 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 be informed of the warning information in a timely manner.
[0004] Although the design in the above document can observe the fire situation through the camera and use the wireless transceiver to issue an early warning, it still has obvious defects in actual use, such as:
[0005] The device in this document installs the camera and fire detector on the same side, which results in a relatively fixed monitoring range. It can only monitor at a specified angle in front of it, making it impossible to provide a wide range of fire warnings, reducing the overall practicality of the device.

Beneficial effects
[0017] The present invention provides a fire early warning monitoring system. Compared with existing technologies, it has the following advantages:
[0018] (1) The fire warning monitoring system uses a warning cleaning mechanism and a monitoring driving mechanism in combination. The two mechanisms can use the drive of the motor to drive the vertical rotating column and the fire detectors and cameras at the bottom and top to rotate to increase the monitoring range. The linkage of the first push rod and the second push rod can make the fire detector and the camera rotate back and forth, so that the motor can rotate in the same direction without the need for reverse start, avoiding frequent start-up and reducing the power consumption during start-up. In addition, during rotation, the linkage between the structures can be used to push the first ring wiping frame and the second ring wiping frame to wipe the fire detector and the camera respectively, effectively improving the overall practicality of the equipment.
[0019] (2) The fire early warning monitoring system is used by installing a second tooth plate and an upper resistance disc on the upper and lower parts of the surface of the vertical rotating column respectively, and is used in conjunction with a first push rod, a second push rod, a first stop block and a second stop block. 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 backward, which can not only improve the monitoring range, but also ensure the overall connectivity of the equipment.
[0020] (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 protective box respectively using a lifting rod. 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.
[0021] (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 location of the fire and observe the fire situation.

The second push rod 216 pushes the turntable 204 and the vertical column 201 to rotate counterclockwise through contact with the second block 206. When the vertical column 201 rotates counterclockwise, it will drive the fire detector 202 and the camera 203 to rotate as well. The fire detector 202 increases the monitoring range by rotating.
[0037] Please refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6, showing the overall structure of the early warning cleaning mechanism 1, the early warning cleaning mechanism 1 includes a protective box 101, the right side of the bottom of the protective box 101 is fixedly connected to the motor 102 through a bracket, the motor 102 is a servo motor, and the output shaft of the motor 102 is fixedly connected to the rotating rod 103 through a coupling, the top of the rotating rod 103 passes through the protective box 101 and extends to the interior of the protective box 101, and the rotating rod 103 extends to the end of the protective box 101 and is rotatably connected to the top of the inner cavity of the protective box 101 through a bearing. The upper and lower parts of the surface of the rotating rod 103 and the interior of the protective box 101 are respectively fixedly connected to the first tooth plate 104 and the first pulley 105, and the inner side of the first pulley 105 is provided with a belt 106. The right side of the top and the left side of the bottom of the protective box 101 are both slidably installed with a lifting rod 107 through an opening, and the ends of the two lifting rods 107 away from the protective box 101 are fixedly connected to the first ring wiping frame 108 and the second ring wiping frame 109 through a fixed plate. Soft brushes are provided on the inner sides of the wiping frame 108 and the second ring wiping frame 109. The upper and lower parts of the surface of the lifting rod 107 are fixedly connected with a back-retracting 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 so as 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. A single-chip microcomputer 116 and a wireless transceiver 117 are respectively installed on both sides of the protective box 101. The single-chip microcomputer 116 is electrically connected to the wireless transceiver 117. The wireless transceiver 117 can communicate and interact with the central control room through 4G, 5G or wireless networks.
[0038] When the circular rotating disk 204 rotates counterclockwise, the first stop 205 and the first push rod 212 rotate relative to each other. When the vertical rotating column 201 rotates counterclockwise 180 degrees, the arc-surface top block 113 at the bottom is inserted between the second push rod 216 and the circular rotating disk 204, and squeezes the second push rod 216 so that the second push rod 216 descends under the limiting effect of the second guide rod 214. After the second push rod 216 descends, it disengages from the second stop 206 and no longer contacts and pushes the second stop 206. At this time, the first push rod 212 contacts the first stop 205 and pushes the first stop 205 to drive the circular rotating disk 204. The vertical column 201 rotates clockwise 180 degrees and reverses. During the rotation, the second push rod 216 separates from the arc top block 113 and is squeezed by the third spring 217 to rise and reset. After the vertical column 201 rotates clockwise 180 degrees, the upper arc top block 113 is inserted between the first push rod 212 and the circular rotating disk 204 to push the first push rod 212 upward and separate it from the first block 205. At this time, the second push rod 216 contacts the second block 206 again and pushes the circular rotating disk 204 and the vertical column 201 to rotate counterclockwise again. In this process, each time the circular rotating disk 204 rotates counterclockwise or clockwise, After rotating 180 degrees to the limit, the diamond arc block 218 will squeeze the two round head blocks 110 separately and individually. After the round head blocks 110 are squeezed, the lifting rod 107 will be used to push the first ring wiping frame 108 or the second ring wiping frame 109 to move up and down, so that the first ring wiping frame 108 and the second ring wiping frame 109 are lowered to wipe the fire detector 202 and the camera 203 to ensure the sensitivity of the fire detector 202 and the clarity of the camera 203. After the diamond arc block 218 is separated from the round head block 110, the lifting rod 107 will be driven to 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 then restart the motor 102 using the wireless transceiver 117.
