Description

Technical Field

[0001] The utility model relates to the technical field of building fire protection, in particular to a building fire protection smoke and temperature detector. Background Art

[0002] Smoke detectors are also called smoke fire detectors, smoke detectors, smoke detectors, smoke probes and smoke sensors. They are mainly used in fire protection systems and are also used in security system construction. They are a typical device that has been converted from space fire protection measures to civilian use. Smoke detectors use ionized smoke sensors inside. Ionized smoke sensors are technologically advanced, stable and reliable sensors that are widely used in various fire alarm systems. Their performance is far superior to gas-sensitive resistor-type fire alarms.

[0003] Building fire protection is an important guarantee to ensure the safety of people and property inside the building. In addition to conventional fire hydrants, safety fire doors and other disaster relief and protection measures, existing buildings are usually equipped with smoke and temperature detectors to detect fire and smoke, so as to facilitate timely response when a fire occurs. This type of detection device is usually installed on the top beam inside the building and can be detected by smoke and temperature sensors.

[0004] The patent name is "CN219180016U", which is published as: A smoke and heat detector for building fire protection. The device in the public document can disassemble and assemble the detector and the main body by setting a convenient disassembly and assembly structure, but the shortcomings of the device in the public document are: because the detector is fixedly installed in the top area of ​​the room, for buildings with high floor spacing, when there is a flame in the room, the smoke generated by the flame can only be slowly discharged from bottom to top to the top of the room. It can be seen that it takes time for the smoke to be discharged from the bottom to the top. During this time period, the detector cannot immediately monitor the smoke generated by the flame, which in turn causes the detector to be unable to monitor the smoke in the first time period, that is, the detector cannot trigger its own alarm function in the first time period. When the detector detects the smoke, the burning area of ​​the flame has been expanded, reducing the use effect of the detector. Based on this, the utility model designs a smoke and heat detector for building fire protection to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the device includes a detector 1 and a base plate 2, the base plate 2 is fixedly mounted on the top of the detector 1, the protective component 3 mounted on the outside of the detector 1 can be disassembled and assembled by threaded connection with the base plate 2, an exhaust component 4 is arranged at the lower end of the protective component 3, the protective component 3 includes a sleeve 301 threadedly mounted on the inside of the base plate 2, and the sleeve 301 is sleeved on the detector 1, the sleeve 301 is made of transparent material, and clearance holes 302 are integrally arranged on the front and rear sides of the upper end of the sleeve 301, and the clearance holes 302 are through-hole design, the exhaust component 4 includes an exhaust fan 401 fixedly mounted on the lower end of the sleeve 301, and a filter screen 402 arranged at the lower end of the exhaust fan 401 is fixedly connected to the sleeve 301.

[0027] First, the staff installs the base plate 2 together with the detector 1 on the top area of ​​the room, and then turns on the exhaust fan 401. The exhaust fan 401 accelerates the flow of indoor gas, so that the gas passes through the filter 402 and is discharged to the detector 1 area, that is, the gas is discharged into the sleeve 301. In addition, the filter 402 filters the dust in the indoor gas to prevent the dust from adhering to the surface of the detector 1, thereby ensuring the cleanliness of the surface of the detector 1, that is, ensuring the accuracy of the detector 1 in monitoring the smoke. The gas discharged into the sleeve 301 is then discharged from the outside of the sleeve through the yield hole 302. When there is a flame generating smoke, the flow of indoor gas is accelerated. At this time, the accelerated indoor gas is in a fast-flowing state together with the smoke, and then the smoke is discharged into the sleeve 301, so that the detector 1 can immediately detect the smoke, and the detector 1 can trigger an alarm within the first time period, which is convenient for the staff to extinguish the flame. Example 2

[0028] like Figure 2 , Figure 4 , Figure 5 As shown, an annular groove 5 is integrally arranged around the lower end of the sleeve 301, and the center of the annular groove 5 is concentric with the center of the sleeve 301. Slide blocks 6 are slidably connected on the left and right sides of the annular groove 5, and the outer side of the slide block 6 extends out from the inside of the annular groove 5. A rack 7 with an annular direction is sleeved on the lower end of the outer side of the sleeve 301. The inner wall of the rack 7 is fixedly connected to the outer side of the slide block 6. The bottom surface of the rack 7 is lower than the bottom surface of the sleeve 301, and a connecting rod 8 is fixedly arranged at the lower end of the rack 7. The connecting rod 8 and the filter screen 402 are in a parallel design state. A number of brushes 9 are fixedly arranged on the top of the connecting rod 8 from left to right, and the end of the brush 9 away from the connecting rod 8 is in contact with the bottom of the filter screen 402. A micro motor 10 with a low speed function is fixedly arranged on the left side of the bottom of the bottom plate 2, and a rotating rod 11 is fixedly arranged at the bottom of the micro motor 10. A gear 12 is fixedly arranged at the bottom of the rotating rod 11, and the gear 12 is meshed with the teeth of the rack 7, and the rotating rod 11 and the connecting rod 8 are in a 90-degree vertical state.

[0029] According to the operation method in Example 1, when the staff turns on the exhaust fan 401, the micro motor 10 can be turned on at the same time. The micro motor 10 drives the rotating rod 11 to drive the gear 12 to rotate. Through the meshing of the gear 12 and the gear 7, the gear 12 drives the rack 7 together with the slider 6, the connecting rod 8 and the brush 9 to rotate around the center of the annular groove 5, so that the rotating brush 9 cleans the dust adhering to the filter 402 to prevent the dust from clogging the filter 402, which not only ensures the normal use of the filter 402, but also ensures the smoothness of the indoor gas passing through the inside of the casing 301 and then being discharged from the outside of the casing 301 through the makeshift hole 302.
