Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and more specifically, to a capsule fire extinguishing device. Background Technology

[0002] When a fire occurs, existing capsule fire extinguishing devices often have a slow response time and cannot quickly start the fire extinguishing process. This delay may cause the fire to spread rapidly in a short period of time, increasing the difficulty and danger of fire extinguishing. In emergency situations, rescuers need devices that can be used immediately and quickly extinguish the fire source. Capsule fire extinguishing devices with poor response may miss the best time to extinguish the fire, resulting in irreparable losses.

[0003] Existing capsule fire extinguishing devices often have a delayed triggering mechanism, which results in an excessively long time from triggering to the release of the extinguishing agent. In the critical stages of fire development, this slow triggering speed may cause the fire to get out of control, making firefighting work complicated and dangerous. Utility Model Content

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a capsule fire extinguishing device, comprising a capsule shell, wherein an instantaneous release mechanism is provided on the outer wall of the capsule shell, the instantaneous release mechanism comprising an outer sleeve, a flow-through sleeve, flow-through holes, a plugging sleeve, and a sealing sleeve, the outer sleeve being installed on the outer wall of the capsule shell, the flow-through sleeve being installed on the top surface of the outer sleeve, multiple sets of flow-through holes being distributed on the outer wall of the flow-through sleeve, the plugging sleeve being slidably installed inside the flow-control sleeve, the sealing sleeve being installed at the bottom end of the plugging sleeve, and a triggering mechanism being provided at the top end of the flow-through sleeve, the triggering mechanism comprising a snap-fit ​​sleeve, a snap-fit ​​block, a snap-fit ​​rod, a snap-fit ​​groove, and a safety assembly, the snap-fit ​​sleeve being installed at the top end of the flow-through sleeve, multiple sets of snap-fit ​​blocks being provided on the inner side of the snap-fit ​​sleeve, the snap-fit ​​rod being installed at the top end of the plugging sleeve, and multiple sets of snap-fit ​​grooves being distributed on the outer wall of the snap-fit ​​rod.

[0008] The present invention is further configured such that the safety component includes a limiting sleeve, a slider, a contraction spring, a stop block, and a hot melt adhesive ring. The limiting sleeve is installed on the outer wall of the snap-fit ​​sleeve, the slider is installed on the outer wall of multiple sets of snap-fit ​​blocks, multiple sets of contraction springs are provided and their two ends are respectively connected to the snap-fit ​​blocks and the limiting sleeve, the stop block is installed on the outer end of multiple sets of sliders, and the limiting sleeve and the stop block are respectively glued to both sides of the hot melt adhesive ring.

[0009] The present invention is further configured such that a one-way valve is installed at one end of the capsule shell. The one-way valve makes the capsule fire extinguishing device safer and more reliable to operate. It avoids the backflow of the extinguishing agent and ensures that the extinguishing agent can be released to the fire source quickly and effectively when a fire occurs, thereby improving the fire extinguishing speed and success rate.

[0010] The present invention is further configured such that a limiting plate is installed at the bottom end of the sealing sleeve, and a limiting rod is installed inside the outer sleeve. Multiple sets of the limiting rod are provided and are slidably connected to the limiting plate. The design of the limiting plate and the limiting rod ensures that the sealing sleeve can maintain the correct position during the release of the extinguishing agent, preventing sealing failure due to pressure changes.

[0011] The present invention is further configured such that each of the multiple sets of limiting rods is provided with a tension spring on its outer wall, and the two ends of the multiple sets of tension springs are respectively connected to the outer sleeve and the limiting plate. The tension springs enable the limiting rods to quickly return to their original positions after the release action is completed, so as to prepare for the next use and improve the reusability and response speed of the device.

[0012] The present invention is further configured such that a sealing ring is installed on the top surface of the sealing sleeve.

They can provide a larger spray area, thereby accelerating the fire extinguishing speed, reducing the amount of fire extinguishing agent used, and improving the overall performance of the capsule fire extinguishing device.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a capsule fire extinguishing device, which has the following beneficial effects:

[0017] 1. Beneficial effects of the instantaneous release mechanism: The design of the instantaneous release mechanism enables rapid and controllable release of the extinguishing agent. The outer sleeve and flow sleeve ensure that the extinguishing agent can be effectively stored and sealed after high-pressure gas is injected into the capsule shell. The distribution of the flow holes optimizes the flowability and spray coverage of the extinguishing agent, allowing the extinguishing agent to be sprayed evenly around the fire source, improving the extinguishing efficiency. The sliding connection of the plug sleeve and sealing sleeve ensures the sealed storage of the extinguishing agent in the non-release state, while it can be quickly opened after triggering to achieve rapid fire extinguishing.

[0018] 2. Beneficial effects of the triggering mechanism: The triggering mechanism provides a reliable release control system through the cooperation of the locking sleeve, locking block, locking rod and locking slot. Under the action of flame, the hot melt adhesive ring in the safety component burns and melts, releasing the blocking block, causing the contraction spring to retract, thereby pushing the locking block to move outward, releasing the locking restriction on the locking rod. This process realizes the rapid release of the extinguishing agent, improves the response speed and ease of operation of the device.

[0019] 3. Beneficial effects of the safety component: The design of the safety component ensures that the triggering mechanism will not be accidentally triggered under normal circumstances. The hot melt adhesive ring provides an easy-to-melt safety mechanism. When the flame comes into contact with the hot melt adhesive ring, it can melt quickly, release the block, and then activate the triggering mechanism. This design improves the safety of the device, avoids misoperation and accidental release, and ensures that the fire extinguishing process can be reliably started in the event of a fire.

[0029] Please see Figures 1-5 A capsule fire extinguishing device includes a capsule shell 1. The outer wall of the capsule shell 1 is provided with an instant release mechanism. The instant release mechanism includes an outer sleeve 2, a flow-through sleeve 3, a flow-through hole 4, a plug sleeve 5, and a sealing sleeve 6. The outer sleeve 2 is installed on the outer wall of the capsule shell 1, the flow-through sleeve 3 is installed on the top surface of the outer sleeve 2, multiple sets of flow-through holes 4 are distributed on the outer wall of the flow-through sleeve 3, the plug sleeve 5 is slidably installed inside the flow-control sleeve, the sealing sleeve 6 is installed at the bottom end of the plug sleeve 5, and a triggering mechanism is provided at the top of the flow-through sleeve 3. The triggering mechanism includes a snap-fit ​​sleeve 7, a snap-fit ​​block 8, a snap-fit ​​rod 9, a snap-fit ​​groove 10, and a safety component 11. The snap-fit ​​sleeve 7 is installed at the top of the flow-through sleeve 3, multiple sets of snap-fit ​​blocks 8 are provided inside the snap-fit ​​sleeve 7, the snap-fit ​​rod 9 is installed at the top of the plug sleeve 5, and multiple sets of snap-fit ​​grooves 10 are distributed on the outer wall of the snap-fit ​​rod 9.

[0030] One-way valve 17 is installed at one end of capsule shell 1. The function of one-way valve 17 is to allow the extinguishing agent to be sprayed from inside the capsule shell to the outside when it is released.

[0031] A limiting plate 18 is installed at the bottom of the sealing sleeve 6, and a limiting rod 19 is installed inside the outer sleeve 2. Multiple sets of limiting rods 19 are provided and are slidably connected to the limiting plate 18. The limiting plate 18 is installed at the bottom of the sealing sleeve 6, and the limiting rod 19 is located inside the outer sleeve 2 and is slidably connected to the limiting plate 18.

[0032] Each of the multiple sets of limiting rods 19 has a tension spring 20 on its outer wall. The two ends of the multiple sets of tension springs 20 are respectively connected to the outer sleeve 2 and the limiting plate 18. The multiple sets of tension springs 20 are connected to the outer sleeve 2 and the limiting plate 18 to provide restoring force, so that the limiting rods 19 can quickly reset after the fire extinguishing agent is released.

[0033] A sealing ring 21 is installed on the top surface of the sealing sleeve 6. The function of the sealing ring 21 is to ensure that the extinguishing agent inside the capsule shell 1 will not leak out due to pressure in the non-release state, thus maintaining the sealing performance and long-term storage stability of the device.

[0034] Both the instantaneous release mechanism and the triggering mechanism are provided with multiple sets distributed on the outer wall of the capsule shell 1. Together they constitute the release control system of the extinguishing agent. Through the triggering mechanism, the instantaneous release mechanism can be quickly activated, so that the extinguishing agent can be sprayed quickly.

[0035] The multiple flow holes 4 are all designed as elongated strips. This design helps to improve the flowability and spray coverage of the extinguishing agent, allowing the extinguishing agent to be distributed more evenly around the fire source.

[0036] In this embodiment, high-pressure gas, such as nitrogen or carbon dioxide, is injected into the capsule shell 1 through the one-way valve 17 to increase the internal pressure. When fire extinguishing is required, the capsule fire extinguishing device is deployed to the burning area, triggering the component to release the restriction on the multiple sets of locking blocks 8, causing the multiple sets of locking blocks 8 to disengage from the locking slot 10 and release the locking rod 9. Subsequently, the multiple sets of tension springs 20 pull the limiting plate 18 to slide along the multiple sets of limiting rods 19, and then pull the sealing sleeve 6 to move and release the sealing ring 21 from the abutment seal of the flow sleeve 3. The sealing sleeve 6 pulls the plug sleeve 5 to slide along the flow sleeve 3, causing the plug sleeve 5 to release the sliding seal on the inner wall of the flow sleeve 3, so that the multiple sets of flow holes 4 discharge the fire extinguishing agent from the capsule shell 1. The released high-pressure gas pushes the fire extinguishing agent in the capsule shell 1 to be ejected at high speed through the flow holes 4.

[0037] Please see Figure 5 As one implementation of the safety component: the safety component 11 includes a limiting sleeve 12, a slider 13, a contraction spring 14, a stop block 15, and a hot melt adhesive ring 16. The limiting sleeve 12 is installed on the outer wall of the snap-fit ​​sleeve 7, the slider 13 is installed on the outer wall of multiple sets of snap blocks 8, multiple sets of contraction springs 14 are provided and their two ends are respectively connected to the snap blocks 8 and the limiting sleeve 12, the stop block 15 is installed on the outer end of multiple sets of sliders 13, and the limiting sleeve 12 and the stop block 15 are respectively glued to both sides of the hot melt adhesive ring 16.

[0038] More specifically, after the burning flame melts the multiple sets of hot melt adhesive rings 16, the adhesive connection between the hot melt adhesive rings 16 and the abutment block 15 is released. Then, the contraction spring 14 retracts and pulls the locking block 8 outward. The slider 13 slides along the limiting sleeve 12 and pulls the locking block 8 out of the slot 10, releasing the restriction on the multiple sets of locking blocks 8, thereby releasing the locking of the locking rod 9.

[0039] In summary, during use or operation of the overall equipment: High-pressure gas, such as nitrogen or carbon dioxide, is injected into the capsule shell 1 via the one-way valve 17, increasing the internal pressure. When fire extinguishing is required, the capsule fire extinguishing device is deployed to the burning area, triggering the components to release the restriction on multiple sets of locking blocks 8, causing them to disengage from the locking slots 10 and release the locking rods 9. Subsequently, multiple sets of tension springs 20 pull the limiting plate 18 to slide along multiple sets of limiting rods 19, then pull the sealing sleeve 6 to move and release the sealing ring 21 from the contact seal of the flow sleeve 3. The sealing sleeve 6 pulls the plug sleeve 5 to slide along the flow sleeve 3, causing the plug sleeve 5 to release the sliding seal on the inner wall of the flow sleeve 3, allowing the multiple sets of flow holes 4 to discharge the fire extinguishing agent from the capsule shell 1. The released high-pressure gas propels the fire extinguishing agent inside the capsule shell 1 through the flow holes 4 at high speed.

[0040] After the burning flame melts the multiple sets of hot melt adhesive rings 16, the adhesive connection between the hot melt adhesive rings 16 and the abutment block 15 is released. Then, the contraction spring 14 retracts and pulls the locking block 8 outward. The slider 13 slides along the limiting sleeve 12 and pulls the locking block 8 out of the slot 10, releasing the restriction on the multiple sets of locking blocks 8, thereby releasing the locking of the locking rod 9.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
