Description

Technical Field

[0001] The present invention relates to the technical field of fire warning equipment, and more particularly to a fire inspection robot with smoke and fire warning functions. Background Art

[0002] Traditional fire monitoring systems usually rely on fixed facilities and manual inspections, and are unable to achieve real-time fire risk monitoring, accurate risk assessment, and timely risk handling. In some chemical plants, there are many flammable and explosive chemical raw materials, which may cause fires; some places with a large number of high-voltage and high-current equipment, such as substations, large equipment electrical control rooms, power tunnels, etc., are prone to circuit failures and fires. Therefore, it is particularly important to strengthen inspection prevention and fire emergency measures.

[0003] In recent years, there have been few studies and reports on rail-type firefighting robots, but wheeled and tracked firefighting robots have been in use. For example, patent application number 201110206090.6 discloses a high-pressure water mist firefighting robot that uses a wheeled walking mechanism and is equipped with fire extinguishing bombs, sensors, visible light cameras, etc. When a fire occurs, it enters the scene and transmits the fire scene situation back to the command center in real time while extinguishing the fire. However, whether it is a wheeled or tracked firefighting robot, it walks on the ground and performs fire monitoring and early warning. The robot itself has limited height and is easily blocked by equipment, tables, chairs and other accessories in the environment. In addition, the robot's continuous walking will also hinder the normal work of the staff.

[0014] In summary, the present invention has the following beneficial technical effects: 1. This application provides rack rails on both sides of the T-shaped track to support and guide the walking part. By pre-customizing the shape of the T-shaped track, the walking part can continuously move on the preset route. And because it is walking on the top of the room, the wide field of vision can provide early warning of fire without affecting the staff.

[0015] 2. This application installs a monitoring camera and a smoke alarm device in the monitoring part, and the cooperation of the active gear and the passive gear can drive the monitoring camera to rotate continuously. During the movement of the walking part, the monitoring camera can continuously scan the surroundings, quickly discover fire hazards, and issue early warnings in time. The suction fan installed in the smoke alarm device can draw outside air in, and the smoke in the air will pass through the photoelectric smoke alarm and be discharged through the air vents. The photoelectric smoke alarm contains a light source (such as an infrared LED) and a photosensitive element (such as a photodiode). When smoke enters the detection area of ​​the alarm, the smoke particles will scatter the light, causing some light to be unable to reach the photosensitive element, thereby generating an electrical signal. By detecting the intensity change of the scattered light, it is possible to determine whether the smoke concentration exceeds the set threshold and trigger the alarm.

[0016] 3. The rolling shaft in the walking part of the present application is installed in the bearing seat and is driven by the cooperation of pulley B, pulley A and belt C. When the belt C needs to be replaced, the threaded cylinder can be pushed upward by the bolt to loosen the diagonal support rod from the tightened state. At this time, the two bearing seats can slide close to each other, making it easier to remove the belt C from the pulley A, which is more convenient.

[0017] 4. The present application also has a pulley E installed on the driven shaft and a pulley D installed on the auxiliary shaft. With the cooperation of the belt F, the auxiliary shaft can be driven to rotate by the driven shaft, and the shaft ring on the auxiliary shaft will push the L-shaped folding rod to rotate around the cylindrical shell, so that the debris on the filter screen can be cleaned away by a cleaning brush to avoid clogging of the filter screen.

The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0028] The implementation principle of a fire inspection robot with smoke and fire warning functions in an embodiment of the present invention is as follows: when in use, a T-shaped track 101 can be installed on the ceiling of a room, and the T-shaped track 101 can be set to an S-shape or a ring shape according to the surrounding environment to provide a cyclic detection path. After that, the screws on the fixing member 105 can be removed, and the maintenance track 103 can be pushed to rotate downward around the hinge member 104. The walking part 2 is placed on the rack track 102 from the maintenance area.

Since it walks on the ceiling of the room, it has a wide field of view and can provide fire warnings without affecting the staff. As the walking unit 2 moves forward, the power shaft 212 rotates continuously. At this time, the cooperation between the bevel gear A 216 and the bevel gear B 217 can synchronously drive the driven shaft 2104 to rotate. The driving gear 2105 and the driven gear 2106 can load the power of the driven shaft 2104 onto the monitoring camera 22, ensuring that the monitoring camera 22 can rotate continuously during the moving unit 2, facilitating real-time monitoring of the surrounding environment, quickly discovering fire hazards, and issuing early warnings in a timely manner. Furthermore, a smoke alarm device is provided. The suction fan 2304 is configured to continuously draw ambient air into the cylindrical housing 2301. The air passes through the photoelectric smoke alarm 2303 and is then discharged from the air vent 2306. When smoke enters the photoelectric smoke alarm 2303, the smoke particles scatter light, preventing some light from reaching the photosensor, thereby generating an electrical signal. By detecting the intensity change of the scattered light, it is possible to determine whether the smoke concentration exceeds a set threshold and trigger an alarm. The cooperation of bevel gear A and bevel gear B can also drive the driven shaft to rotate, and a pulley E is installed on the driven shaft, and a pulley D is installed on the auxiliary shaft. With the cooperation of belt F, the auxiliary shaft can be driven to rotate by the driven shaft, and the shaft ring on the auxiliary shaft will push the L-shaped folding rod to rotate around the cylindrical shell, so that the debris on the filter screen can be cleaned away by the cleaning brush to avoid clogging of the filter screen and affecting the monitoring effect.
