Description

Technical Field

[0001] The invention relates to the field of fire-fighting equipment detection, in particular to an air tightness detection device for a fire-fighting fire extinguisher. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool that contains chemicals and is used to put out fires. Fire extinguishers are one of the most common firefighting equipment and are stored in public places or places where fires may occur. Different types of fire extinguishers contain different ingredients and are designed for different causes of fire. Care must be taken when using them to avoid adverse effects and danger.

[0003] The air tightness detection of fire extinguishers is a key link to ensure their normal operation. The water immersion method is mainly used for detection. This method immerses the test bottle filled with specified pressure gas into a water tank to check its air tightness. The existing Chinese public patent document: CN220322624U discloses a fire extinguisher air tightness detection device. The top plate, the material transfer plate and the installation cylinder constitute a lifting structure, so that when the material transfer plate rotates on the side of the installation turntable, the distance between the arc-shaped material transfer plate and the baffle can be changed and adjusted, so that the material transfer plate can push fire extinguishers of different diameters into the water tank for air tightness detection. However, when the fire extinguisher is immersed in water for detection, in order to observe the leakage point, the fire extinguisher needs to be in a state of self-rotation to perform a comprehensive air tightness detection on the fire extinguisher. However, it is difficult to make the fire extinguisher rotate by rotating through a turntable, and when multiple fire extinguishers are sent into the water, it is difficult to determine which fire extinguisher has a leak, which reduces the accuracy of the air tightness detection.

[0024] The material storage mechanism includes a water baffle 24 fixedly mounted on the bottom inner wall of the device housing 1, a guide ramp 25 fixedly mounted on the top of the water baffle 24, the left side of the guide ramp 25 is located on the right side of the conveyor belt 15, and an opening for the push bar 23 to limit the sliding of the guide ramp 25 is provided on the left side of the guide ramp 25, so that the conveyor belt 15 pushes the fire extinguisher onto the guide ramp 25, and a plurality of equally spaced limit rods 26 are arranged above the guide ramp 25, and connecting rods 27 are fixedly mounted on both ends of the limit rod 26, and the connecting rod 27 is rotatably mounted on the inner side of the device housing 1, and two limit rods 26 are fixedly mounted on the outer side of the limit rod 26. The arc rods 28 are symmetrically distributed, and the arc rods 28 slide through the guide inclined plate 25. The top of the guide inclined plate 25 is provided with an arc groove for the limit rod 26 to slide, so that multiple fire extinguishers can push the limit rod 26 to swing into the arc groove, so as to realize the separate storage of multiple fire extinguishers. A mounting plate 29 located below the guide inclined plate 25 is fixedly connected between the two arc rods 28. An arc spring 30 is arranged on the outer side of the arc rod 28. The arc spring 30 is fixedly installed between the mounting plate 29 and the guide inclined plate 25, so that the mounting plate 29 drives the limit rod 26 to reset through the arc rod 28; When the conveyor belt 15 conveys the fire extinguisher to the guide inclined plate 25, the fire extinguisher can contact the leftmost limit rod 26 along the inclined surface of the guide inclined plate 25, and when the fire extinguisher contacts the limit rod 26, the arc rod 28 on the limit rod 26 is pushed to slide downward, and the rebound force of the arc spring 30 is used to provide a buffer for the contact between the fire extinguisher and the limit rod 26. When the next fire extinguisher contacts the fire extinguisher, the weight of the two fire extinguishers pushes the limit rod 26 to swing and insert into the arc groove of the guide inclined plate 25, and the fire extinguisher can contact the next limit rod 26. Thus, multiple fire extinguishers are separated by multiple limit rods 26, and the limit rods 26 provide protection for the fire extinguishers to prevent the accumulation of fire extinguishers, so as to facilitate the determination of leaking fire extinguishers and qualified fire extinguishers, thereby achieving the effect of facilitating batch storage and retrieval.

[0025] Working principle: First, the user places the fire extinguisher between the two clamping rings 2 and rotates the bidirectional screw 6. The bidirectional screw 6 drives the two moving blocks 5 to approach each other, so that the moving block 5 drives the clamping ring 2 to be close to the end of the fire extinguisher through the support plate 4 and the mounting frame 3. The clamping ring 2 drives the abutment 13 to abut the surface of the fire extinguisher through the slide bar 10. As the clamping ring 2 moves, the slide bar 10 stretches the tension spring 12 through the limit block 11, and uses the elastic force of the tension spring 12 to firmly clamp the fire extinguisher. At this time, the user rotates the rotating rod 8 to make the rotating rod 8 rotate through the clamping ring 2 of the mounting frame 3, and the clamping ring 2 drives the fire extinguisher to rotate synchronously through the abutment 13, so that The fire extinguisher rotates along the water surface in the device housing 1 to detect the air tightness of the fire extinguisher, so as to find the leakage point of the fire extinguisher in time. Then, the user rotates the two bidirectional screws 6 again to make the two clamping rings 2 away from the fire extinguisher, and the fire extinguisher floats on the water surface, and the mounting frame 3 pushes the rotating rod 8 to move, so that the rotating rod 8 drives the mounting ring 17 to lean against the outer side of the gear 19, and the plug column 18 on the mounting ring 17 is inserted into the plug hole of the gear 19. Then, the user rotates the rotating rod 8, and the rotating rod 8 drives the gear 19 to rotate, so that the gear 19 drives the corresponding roller rod 16 to rotate through the gear 20 and the synchronous belt 21, and the roller rod 16 cooperates with another roller rod 16 drives the conveyor belt 15 to rotate and move, and the conveyor belt 15 drives the push bar 23 on the installation bar 22 to contact the outer side of the fire extinguisher, pushing the fire extinguisher to stagger with the clamp ring 2, so that the user can test the next fire extinguisher, and separate and transport multiple fire extinguishers through multiple installation bars 22 on the conveyor belt 15, and use the inclined surface of the conveyor belt 15 to keep the fire extinguisher away from the water surface of the device housing 1, so that the fire extinguisher can filter water and is easy to clean. Finally, the conveyor belt 15 sends multiple fire extinguishers to the guide inclined plate 25 in sequence, and the first fire extinguisher can contact with the leftmost limit rod 26 along the inclined surface of the guide inclined plate 25, and When contacting with the limit rod 26, the arc rod 28 on the limit rod 26 is pushed to slide downward, and the rebound force of the arc spring 30 is used to provide a buffer for the contact between the first fire extinguisher and the limit rod 26. When the second fire extinguisher contacts with the first fire extinguisher, the weight of the two fire extinguishers is used to push the limit rod 26 to swing and insert it into the arc groove of the guide inclined plate 25. The first fire extinguisher can contact with the next limit rod 26. Thus, multiple fire extinguishers are separated and stored by multiple limit rods 26, which is convenient for users to take and prevent collision and accumulation, thereby achieving the effect of comprehensive detection and convenient water filtering and material taking.

[0026] Example 2: Please refer to Figure 1-Figure 3The present embodiment further explains the first embodiment. Adjustment handles 31 are fixedly installed at both ends of the bidirectional screw 6 in the figure for rotationally adjusting the bidirectional screw 6. A glass observation panel 32 is fixedly installed on the left side of the device housing 1 for observing the air tightness detection of the fire extinguisher. A plurality of rubber strips 33 equidistantly distributed are fixedly installed on the arc surface of the stop block 13 to increase the friction between the stop block 13 and the fire extinguisher for anti-slip.

[0027] In this embodiment: the user can adjust the bidirectional screw 6 by rotating the adjustment handle 31. When the block 13 contacts the end of the fire extinguisher, the friction between the block 13 and the surface of the fire extinguisher can be increased by the rubber strip 33, so that the fire extinguisher can be firmly positioned to prevent slipping. When the fire extinguisher is rotated, the air tightness of the fire extinguisher can be observed through the glass observation panel 32, so as to observe the leakage point of the fire extinguisher.

[0028] Example 3: Please refer to Figure 4 , Figure 7 and Figure 8 This embodiment further illustrates other embodiments. The end of the plug post 18 in the figure away from the mounting ring 17 is an arc surface structure. The number of holes on the gear 19 is greater than the number of the plug post 18, which facilitates the alignment of the plug post 18 with the holes on the mounting ring 17. An anti-slip sleeve 34 is fixedly installed on the outer side of the limit rod 26 to provide protection for the fire extinguisher. A plurality of equally spaced water-permeable holes are provided on the top of the guide ramp 25 to facilitate the discharge of residual water on the fire extinguisher.

[0029] In this embodiment: when the mounting ring 17 is against the gear 19, the arc surface of the plug post 18 can be quickly aligned and inserted with the socket on the gear 19, and the number of sockets on the gear 19 is greater than the number of the plug posts 18, which is convenient for the mounting ring 17 to quickly connect with the gear 19 through the plug posts 18. When the tested fire extinguisher is close to the limit rod 26, the anti-slip sleeve 34 can provide buffering and shock absorption between the limit rod 26 and the fire extinguisher, and prevent the fire extinguisher from slipping, thereby providing protection for the fire extinguisher. In addition, the water remaining on the surface of the fire extinguisher can be discharged into the device housing 1 along the inclined surface of the guide inclined plate 25 and the water permeable hole, so as to facilitate secondary water filtration.
