Description

Technical Field

[0001] The present invention relates to the field of prefabricated cabins, and in particular to a safety monitoring system for prefabricated cabins of outdoor equipment. Background Art

[0002] In outdoor equipment operation scenarios, prefabricated cabins are important carriers, and their internal safety is crucial. Because prefabricated cabins typically house various electrical equipment, fires can occur during operation due to line aging, overloads, short circuits, and other factors. Smoke generated in the early stages of a fire is an important early warning signal.

[0003] Traditional prefabricated cabin smoke monitoring devices are mostly fixed installations. This installation method has obvious limitations. The detection range is relatively fixed and limited, making it difficult to fully cover the prefabricated cabin. This easily leads to blind spots in monitoring, resulting in fire hazards not being discovered in a timely manner.

[0004] In addition, some existing monitoring systems lack an effective gas flow coordination structure, and the smoke diffuses slowly and unevenly in the cabin, making it difficult for the smoke alarm to quickly sense the smoke and taking a long time to respond. It is impossible to issue an alarm in time at the early stage of the fire, thereby delaying the best time to extinguish the fire, causing serious safety hazards and economic losses to the outdoor equipment prefabricated cabin and its internal equipment. Therefore, we need to consider developing a safety monitoring system for outdoor equipment prefabricated cabins that can expand the detection range and respond in a timely manner. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the existing technology and propose an outdoor equipment prefabricated cabin safety monitoring system.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The outdoor equipment prefabricated cabin safety monitoring system includes a mobile monitoring mechanism, wherein the mobile monitoring mechanism includes a mounting bar, the lower end of the mounting bar is provided with a slide groove, and a rotating shaft is rotatably connected between the left and right inner walls of the slide groove, the rotating shaft is provided with a reciprocating threaded layer, the reciprocating threaded layer of the rotating shaft is threadedly connected with a slider, the lower end of the slider is fixedly connected to a connecting rod, and the lower end of the connecting rod is fixedly connected to a smoke alarm; a gas flow mechanism, the gas flow mechanism includes a vertical plate fixedly connected to the lower order of the mounting bar, the right side of the vertical plate is fixedly connected to a piston cylinder, the inner bottom space of the piston cylinder is connected to the smoke alarm space through a first one-way tube, and the inner bottom space of the piston cylinder is connected to a second one-way tube; a gas filtering mechanism, the gas filtering mechanism includes a filter cylinder fixedly connected to the air inlet of the smoke alarm, and the filter cylinder is provided with a plurality of filter holes; a cleaning mechanism, the cleaning mechanism is used to clean the multiple filter holes.

[0010] Preferably, a first one-way valve is installed at one end of the first one-way tube close to the piston cylinder, and a second one-way valve is installed inside the second one-way tube.

[0011] Preferably, the cleaning mechanism includes a gas storage cylinder fixedly connected to the left side of the vertical plate, the other end of the second one-way tube is connected to the right side space of the gas storage cylinder, the one-way gas flow direction of the first one-way valve is that the smoke alarm enters the piston cylinder in one direction, and the one-way gas flow direction of the second one-way valve is that the piston cylinder enters the gas storage cylinder in one direction.

[0012] Preferably, a drive shaft is provided through the vertical plate, the drive shaft is rotatably connected to the vertical plate, and transmission wheels are installed on the drive shaft and the rotating shaft, and the two transmission wheels are connected by transmission belts. The right end of the drive shaft is fixedly connected to a rotating disk, and a second piston plate that can slide up and down is provided in the piston cylinder, and the right eccentric point of the rotating disk is rotatably connected to the upper end of the second piston plate through a connecting rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

[0018] 3. The air is filtered through the filter cartridge before entering the smoke alarm. Multiple filter holes intercept dust to prevent dust from affecting the internal detection sensor, ensuring the accuracy of the detection data and reducing false alarms and missed alarms.

[0019] 4. When the driving motor stops, the cleaning mechanism uses the stored gas to back-blow and clean the filter holes to prevent dust clogging, extend the service life of the filter cartridge and the entire system, and reduce equipment maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

The output shaft of the drive motor 5 extends into the chute 14 and is fixedly connected to the right end of the rotating shaft 12;

[0029] As an embodiment of the present invention, mounting plates 2 are fixedly connected to both sides of the mounting bar 1. Both mounting plates 2 are provided with mounting holes 3. Through the mounting holes 3, the entire mounting bar 1 can be mounted on the inner top of the cabin. Furthermore, the length of the mounting bar 1 can be set according to the length of the cabin to meet actual usage requirements.

[0030] As an embodiment of the present invention, a gas flow mechanism is further included. Through the gas flow mechanism, a rapid and timely response to smoke can be achieved, and the speed of the effect can be improved. The gas flow mechanism includes a vertical plate 10 fixedly connected to the lower portion of the mounting bar 1. A piston cylinder 23 is fixedly connected to the right side of the vertical plate 10. The inner bottom space of the piston cylinder 23 is connected to the space of the smoke alarm 11 through a first one-way tube 15. The inner bottom space of the piston cylinder 23 is connected to a second one-way tube 24. A first one-way valve 16 is installed at one end of the first one-way tube 15 near the piston cylinder 23. A second one-way valve is installed inside the second one-way tube 24.

[0031] As an embodiment of the present invention, a gas filtering mechanism is further included. The gas filtering mechanism includes a filter cartridge 8 fixedly connected to the air inlet of the smoke alarm 11. The filter cartridge 8 is provided with a plurality of filter holes 9. The filter holes 9 can intercept dust in the air to avoid affecting the use of the internal detection sensor.

[0032] As an embodiment of the present invention, it also includes a cleaning mechanism, which is used to clean the multiple filter holes 9. The cleaning mechanism includes a gas storage cylinder 27 fixedly connected to the left side of the vertical plate 10, and the other end of the second one-way tube 24 is connected to the right side space of the gas storage cylinder 27. The one-way gas flow direction of the first one-way valve 16 is for the smoke alarm 11 to enter the piston cylinder 23 in one direction, and the one-way gas flow direction of the second one-way valve is for the piston cylinder 23 to enter the gas storage cylinder 27 in one direction. A drive shaft 19 is provided through the vertical plate 10, and the drive shaft 19 is rotatably connected to the vertical plate 10. A transmission wheel 18 is installed on the drive shaft 19 and the rotating shaft 12. The two transmission wheels 18 are connected by a transmission belt 17. The right end of the drive shaft 19 is fixedly connected to the rotating disk 20. A second piston plate 31 that can slide up and down is provided in the piston cylinder 23. The rotating disk The right eccentric point of 20 is rotatably connected to the upper end of the second piston plate 31 through a connecting rod 22. A first piston plate 30 that can slide left and right is provided inside the gas storage cylinder 27. The left side of the first piston plate 30 is elastically connected to the left inner wall of the gas storage cylinder 27 through a spring 29. A through opening 28 is provided on the left wall of the gas storage cylinder 27. The right side space of the gas storage cylinder 27 is connected to the middle part of the first one-way tube 15 through a release pipe 25. A normally open solenoid valve 26 is installed inside the release pipe 25. The normally open solenoid valve 26 and the drive motor 5 are in the same series circuit. In this way, when the gas flow mechanism is running, the gas can be stored in the gas storage cylinder 27. When the subsequent gas flow mechanism stops running, this part of the gas is released and enters the smoke alarm 11, and is finally discharged from multiple filter holes 9 for backblowing to achieve cleaning.

[0033] In the present invention, the mounting bar 1 is mounted on the top of the prefabricated cabin through the mounting hole 3 on the mounting plate 2. The drive motor 5 can be controlled to start once every five minutes and stop moving one minute after starting. When the drive motor 5 starts, its output shaft drives the rotating shaft 12 to rotate. Since the rotating shaft 12 is provided with a reciprocating thread layer 13, and the slider 6 is threadedly connected to the reciprocating thread layer 13 and slidably connected to the inner wall of the slide groove 14, when the rotating shaft 12 rotates, the slider 6 slides back and forth in the slide groove 14. The slider 6 drives the smoke alarm 11 to move synchronously through the connecting rod 7, thereby expanding the smoke detection range in the prefabricated cabin, effectively expanding the smoke detection range in the prefabricated cabin, reducing the monitoring blind area, and being able to discover fire hazards more timely.

[0034] When the rotating shaft 12 rotates, the driving shaft 19 is driven to rotate by the transmission wheel 18 and the transmission belt 17, and the driving shaft 19 drives the rotating disk 20 to rotate. The rotating disk 20 drives the second piston plate 31 in the piston cylinder 23 to slide back and forth up and down through the connecting rod 22. When the second piston plate 31 slides upward, negative pressure is formed in the bottom space of the piston cylinder 23, and the air (which may contain smoke) near the smoke alarm 11 is sucked into the piston cylinder 23 through the first one-way tube 15 (the first one-way valve 16 controls the one-way gas flow from the space of the smoke alarm 11 into the piston cylinder 23); when the second piston plate 31 slides downward, the gas in the bottom space of the piston cylinder 23 is compressed and pressed into the gas storage cylinder 27 through the second one-way tube 24 (the second one-way valve controls the one-way gas flow from the piston cylinder 23 into the gas storage cylinder 27), causing the first piston plate 30 to continuously move left and compress the spring 29 to achieve temporary storage of gas. The gas flow mechanism accelerates the flow of air in the prefabricated cabin through the reciprocating motion of the second piston plate 31, so that smoke can be sucked into the smoke alarm 11 more quickly, thereby improving the system's response speed to smoke and helping to issue an alarm in time at the early stage of a fire.

[0035] When air is sucked into the smoke alarm 11, it first passes through the filter cartridge 8. The multiple filter holes 9 on the filter cartridge 8 intercept dust in the air to prevent the dust from affecting the use of the detection sensor inside the smoke alarm 11.

[0036] The normally open solenoid valve 26 and the drive motor 5 are in the same series circuit. When the drive motor 5 is working, the normally open solenoid valve 26 is in the open state, the gas flow mechanism operates normally, and the gas is stored in the gas storage cylinder 27. When the drive motor 5 stops working, the normally open solenoid valve 26 is closed, and the gas in the space on the right side of the gas storage cylinder 27 pushes the first piston plate 30 to the right under the elastic force of the spring 29, and presses the gas into the middle of the first one-way tube 15 through the release pipe 25, and finally enters the smoke alarm 11 and is discharged from multiple filter holes 9, backblowing the filter holes 9 to effectively prevent dust from clogging the filter holes 9, extending the service life of the filter cylinder 8 and the entire system, and reducing maintenance costs.
