Description

Technical Field

[0001] This utility model relates to the field of smoke generator cotton rope fire extinguishing technology, specifically an automatic ignition and fire extinguishing mechanism applied to cotton rope smoke generators. Background Technology

[0002] When a fire occurs, fire detectors automatically detect changes in indoor smoke and heat, thus indicating the presence of a fire. If not detected in time, the fire can spread, causing loss of life and economic damage. Therefore, it is necessary to use a smoke generator to ignite a cotton rope and then conduct a detection experiment.

[0003] Traditional cotton rope fire smoke generators are all operated manually. Existing cotton rope fire smoke generators, due to the manual ignition and extinguishing processes, reduce the efficiency of the smoke generator, pose certain dangers, and are not conducive to practical application and operation.

[0004] Therefore, those skilled in the art provide an automatic ignition and extinguishing mechanism for cotton rope smoke generators to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic ignition and extinguishing mechanism for cotton rope smoke generators, which solves the problems mentioned in the background art, such as reduced efficiency and inherent dangers of smoke generators due to manual ignition and extinguishing operations.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic ignition and extinguishing mechanism for a cotton rope smoke generator, comprising a base plate, a fixing frame installed on the top of the base plate, an extinguishing stone and a fixing box installed on the top of the base plate and below the fixing frame, the fixing box being located on one side of the extinguishing stone, and an electric heating wire being installed on the extinguishing stone.

[0007] The fixed box is equipped with a fire extinguishing component, which includes a fire extinguishing tongue located above the heating wire. The fire extinguishing component is used to move the fire extinguishing tongue left and right.

[0008] Through the above technical solution, the fire extinguishing component can automatically control the locking tongue to move when the cotton rope needs to be ignited, thereby bringing the cotton rope into contact with the heating wire for easy ignition. Simultaneously, when the cotton rope needs to be extinguished, the fire extinguishing component controls the locking tongue to move again, enabling rapid extinguishing of the fire with the help of a fire extinguishing stone. This replaces traditional manual ignition and extinguishing operations, greatly improving the efficiency of the smoke generator and reducing safety hazards, thus benefiting practical application and operation.

[0009] Preferably, the fire extinguishing assembly further includes a movable slot, a movable slot, a movable plate, a movable rod, a spring, a push-pull electromagnet, and a suction cup electromagnet. The movable slot and the movable slot are respectively opened at both ends inside the fixed box. The movable plate slides inside the movable slot. The movable rod is fixed inside the movable plate. One end of the movable rod extends to the outside of the fixed box, and the other end extends to the inside of the movable slot. The fire extinguishing tongue is fixed on the end of the movable rod located outside the fixed box. The spring is sleeved on the outside of the movable rod and located between the movable plate and the inner wall of the movable slot. The push-pull electromagnet is fixed on the end of the movable rod located inside the movable slot. The suction cup electromagnet is fixedly installed inside the movable slot.

[0010] Preferably, the magnetic poles of the push-pull electromagnet and the suction cup electromagnet are opposite when the sides of the two magnets are energized.

[0011] With the above technical solution, when both are energized, the mutual attraction between the magnetic poles can attract the push-pull electromagnet to the suction cup electromagnet. At this time, the moving rod drives the moving plate to move inside the movable slot and squeezes the spring. The spring is in a compressed state. When the power is off, the elastic force of the spring can drive the moving plate, the moving rod, and the push-pull electromagnet to move, so that the push-pull electromagnet is detached from the suction cup electromagnet. The moving rod can also drive the fire extinguishing tongue to move, thereby completing a series of operations.

[0012] Preferably, the bottom of the fixed frame is provided with a cotton rope conveying assembly for conveying cotton rope. The cotton rope conveying assembly includes a first U-shaped plate, an electric push rod, a second U-shaped plate, two conveying wheels, and a motor. The first U-shaped plate is fixed to the bottom of the fixed frame, the electric push rod is installed on one side of the fixed frame, the second U-shaped plate is installed on the piston rod of the electric push rod, the top of the second U-shaped plate is slidably connected to the bottom of the fixed frame, the two conveying wheels are respectively rotatably connected inside the first U-shaped plate and the second U-shaped plate, the motor is installed on the outside of the first U-shaped plate, and the output shaft of the motor is fixedly connected to the corresponding conveying wheel.

[0013] Preferably, the outer side of the middle part of the conveyor wheel is provided with a groove for use with the cotton rope.

[0014] With the above technical solution, during operation, the cotton rope is placed inside the groove on the outside of the conveyor wheel inside the first U-shaped plate. Then, by operating the electric push rod, the second U-shaped plate and the corresponding conveyor wheel are moved. The cotton rope is pressed by the action of the two conveyor wheels and the groove on the outside. At this time, by operating the motor, one of the conveyor wheels is driven to rotate, and the cotton rope is conveyed by friction.

[0015] Preferably, the top of the fixing frame and above the two conveyor wheels has a through hole.

[0016] The above technical solution allows cotton ropes to be easily passed through the fixing frame using through holes.

[0017] Preferably, a control panel is installed on the outside of the fixing frame, and the heating wire, push-pull electromagnet, suction cup electromagnet, electric push rod and motor are all electrically connected to the control panel.

[0018] The above technical solution allows for convenient control of the overall operation of the equipment via a control panel.

[0019] This utility model provides an automatic ignition and extinguishing mechanism for cotton rope smoke generators, which has the following beneficial effects:

[0020] This automatic ignition and extinguishing mechanism for cotton rope smoke generators, through the inclusion of an extinguishing component, automatically controls the movement of the locking tongue when ignition is needed, bringing the cotton rope into contact with the heating wire for easy ignition. Conversely, when extinguishing is required, the extinguishing component controls the locking tongue to move again, enabling rapid extinguishing of the cotton rope with the help of an extinguishing stone. This replaces traditional manual ignition and extinguishing operations, significantly improving the efficiency of the smoke generator and reducing safety hazards, thus benefiting practical application and operation.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1 and Figure 2 This utility model provides an automatic ignition and extinguishing mechanism for a cotton rope smoke generator, including a base plate 1, with a fixing frame 2 mounted on top of the base plate 1. An extinguishing stone 3 and a fixing box 5 are mounted on top of the base plate 1 and below the fixing frame 2, with the fixing box 5 located on one side of the extinguishing stone 3. The extinguishing stone 3 is made of a metal with high thermal conductivity, which can lower the ignition point temperature, thereby achieving the purpose of extinguishing the fire. An electric heating wire 4 is also installed on the extinguishing stone 3, which allows for rapid ignition of the cotton rope.

[0030] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In one aspect of this embodiment, a fire extinguishing assembly is provided inside the fixed box 5. The fire extinguishing assembly includes a fire extinguishing tongue 6, a movable groove 7, a moving groove 8, a moving plate 9, a moving rod 10, a spring 11, a push-pull electromagnet 12, and a suction cup electromagnet 13. The movable groove 7 and the moving groove 8 are respectively opened at both ends inside the fixed box 5, and the moving plate 9 slides inside the movable groove 7. The moving rod 10 is fixed inside the moving plate 9, with one end extending to the outside of the fixed box 5 and the other end extending into the moving groove 8. The fire extinguishing tongue 6 is fixed to the end of the moving rod 10 located on the outside of the fixed box 5. The fire extinguishing tongue 6 is located above the heating wire 4, ensuring that the cotton rope will not contact the heating wire 4 when fire extinguishing is required. The operation of other components inside the fire extinguishing assembly can drive the fire extinguishing tongue 6 to move left and right. The spring 11 is sleeved on the outside of the moving rod 10 and located between the moving plate 9 and the inner wall of the movable groove 7. The push-pull electromagnet 12 is fixed to one end of the moving rod 10 located inside the moving slot 8. The suction cup electromagnet 13 is fixedly installed inside the moving slot 8. When the sides of the push-pull electromagnet 12 and the suction cup electromagnet 13 that are close to each other are energized, their magnetic poles are opposite. When both are energized, as... Figure 5As shown, by utilizing the mutual attraction between magnetic poles, the push-pull electromagnet 12 can be attracted to the suction cup electromagnet 13. At this time, the moving rod 10 drives the moving plate 9 to move inside the movable slot 7 and squeezes the spring 11. At this time, the spring 11 is in a compressed state. When the power is cut off, the elastic force of the spring 11 can drive the moving plate 9, the moving rod 10 and the push-pull electromagnet 12 to move, so that the push-pull electromagnet 12 is detached from the suction cup electromagnet 13. Furthermore, by utilizing the moving rod 10, the fire extinguishing tongue 6 can be moved, thereby completing a series of operations.

[0031] Reference Figure 4 and Figure 6 In one aspect of this embodiment, a cotton rope conveying assembly for conveying cotton rope is provided at the bottom of the fixed frame 2. The cotton rope conveying assembly includes a first U-shaped plate 14, an electric push rod 15, a second U-shaped plate 16, two conveying wheels 17, and a motor 18. The first U-shaped plate 14 is fixed to the bottom of the fixed frame 2. The electric push rod 15 is installed on one side of the fixed frame 2, and the second U-shaped plate 16 is installed on the piston rod of the electric push rod 15. The top of the second U-shaped plate 16 is slidably connected to the bottom of the fixed frame 2. The two conveying wheels 17 are rotatably connected inside the first U-shaped plate 14 and the second U-shaped plate 16, respectively. At the same time, grooves for cooperating with cotton rope are opened on the outer side of the middle part of each conveying wheel 17. The grooves can better fit the cotton rope for use and facilitate the conveying of cotton rope. The motor 18 is installed on the outer side of the first U-shaped plate 14, and the output shaft of the motor 18 is fixedly connected to the corresponding conveying wheel 17. The operation of the motor 18 can drive the conveying wheel 17 to rotate. A through hole 19 is provided at the top of the fixed frame 2, above the two conveyor wheels 17, allowing the cotton rope to be easily passed through the fixed frame 2. During operation, the cotton rope is placed inside the groove on the outside of the conveyor wheel 17 inside the first U-shaped plate 14. Then, by operating the electric push rod 15, the second U-shaped plate 16 and the corresponding conveyor wheel 17 are moved. The cotton rope is pressed together by the action of the two conveyor wheels 17 and the outer groove. At this time, by operating the motor 18, one of the conveyor wheels 17 is driven to rotate, and the cotton rope is conveyed by friction.

[0032] Reference Figure 1 In one aspect of this embodiment, a control panel 20 is installed on the outside of the mounting bracket 2. The heating wire 4, the push-pull electromagnet 12, the suction cup electromagnet 13, the electric push rod 15 and the motor 18 are all electrically connected to the control panel 20, and the control panel 20 is used to conveniently control the operation of the entire device.

[0033] Working principle:

[0034] In use, first power on the entire device. Control the push-pull electromagnet 12 and the suction cup electromagnet 13 via the control panel 20. Utilizing the mutual attraction between the magnetic poles, the push-pull electromagnet 12 is attracted to the suction cup electromagnet 13. At this time, the moving rod 10 moves the moving plate 9 within the movable slot 7, compressing the spring 11. The spring 11 is then in a compressed state. Figure 2 and Figure 5 As shown, the moving rod 10 can simultaneously move the fire extinguishing tongue 6 away from the fire extinguishing stone 3.

[0035] Then, the cotton rope is passed through the through hole 19 and placed inside the groove on the outside of the conveyor wheel 17 inside the first U-shaped plate 14. Then, the electric push rod 15 is controlled by the control panel 20 to push the second U-shaped plate 16 and the corresponding conveyor wheel 17 to move. The cotton rope is pressed by the action of the two conveyor wheels 17 and the groove on the outside. At this time, the motor 18 is controlled by the control panel 20 to drive one of the conveyor wheels 17 to rotate. The cotton rope is conveyed by friction.

[0036] The bottom of the cotton rope is fed to, for example... Figure 2 At the indicated location, the push-pull electromagnet 12 and the suction cup electromagnet 13 are de-energized via the control panel 20. Using the elastic force of the spring 11, the moving plate 9, the moving rod 10, and the push-pull electromagnet 12 are moved, causing the push-pull electromagnet 12 to disengage from the suction cup electromagnet 13. Furthermore, using the moving rod 10, the fire extinguishing tongue 6 is moved towards the side closest to the fire extinguishing stone 3. Figure 3 As shown, at this time, the extinguishing tongue 6 presses the cotton rope to the outside of the fire extinguishing stone 3, and the bottom of the cotton rope contacts the heating wire 4. At this time, the heating wire 4 is controlled by the control panel 20 to work and ignite the cotton rope. Then, the push-pull electromagnet 12 and the suction cup electromagnet 13 are energized again by the control panel 20, so that the push-pull electromagnet 12 is attracted to the suction cup electromagnet 13. The moving rod 10 can drive the extinguishing tongue 6 to move away from the fire extinguishing stone 3. Then the smoke detection experiment can be started.

[0037] After the experiment is completed, the cotton rope needs to be extinguished. At this time, the motor 18 is controlled by the control panel 20 to work, driving one of the conveyor wheels 17 to rotate in the opposite direction. Using the friction force, the cotton rope is pulled back. Figure 4As shown, when the cotton rope is located on one side of the fire extinguishing stone 3, the push-pull electromagnet 12 and the suction cup electromagnet 13 are de-energized by the control panel 20. The elastic force of the spring 11 drives the moving rod 10 and the fire extinguishing tongue 6 to move towards the side closer to the fire extinguishing stone 3. The fire extinguishing stone 3 is used to press the smoldering point at the bottom of the cotton rope against the outside of the fire extinguishing stone 3, reducing the temperature of the smoldering point and thus achieving the purpose of extinguishing the fire. This replaces the traditional manual ignition and extinguishing operation, greatly improving the efficiency of the smoke generating device and reducing the safety hazards of the equipment, which is beneficial to practical application and operation.
