Description

Technical Field

[0001] This application relates to the field of fire protection facilities technology, and in particular to a gas extinguishing agent release device. Background Technology

[0002] A gaseous fire extinguishing agent release device is a device used to release gaseous fire extinguishing agents into a specific protected area during a fire. Based on installation methods, they are divided into three types: ceiling-mounted, wall-mounted, and floor-standing, all of which are linked to a fire alarm system. When the fire alarm system detects a fire signal, it sends an activation command to the gaseous fire extinguishing agent release device. Upon receiving the command, the device opens the valve of the fire extinguishing agent storage container through electromagnetic or mechanical means, allowing the gaseous fire extinguishing agent to be delivered under pressure along pipelines to the protected area, rapidly flooding the entire protected space to extinguish the fire. The gas typically used is heptafluoropropane, which is colorless, odorless, non-conductive, does not pollute the protected object, and will not damage equipment. It is widely used in computer rooms, data centers, power distribution rooms, and other similar locations.

[0003] To ensure even coverage of the entire protected area, computer rooms often employ ceiling-mounted gaseous fire extinguishing agent release systems. However, traditional ceiling-mounted systems have several shortcomings in practical use. For example, in terms of maintenance, these systems typically use multiple bolts to secure them to the ceiling. Since heptafluoropropane extinguishing agents have a limited shelf life and require timely replacement, removing or replacing the bolts is challenging due to the system's high ceiling location and limited operating space. Workers often need ladders or lifts, making operation difficult and increasing the risk of damage to the ceiling due to instability. Furthermore, sequentially removing and installing multiple bolts is time-consuming. Since maintenance personnel are working at height during disassembly, prolonged high-altitude work increases the overall maintenance time and the probability of accidents. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that traditional ceiling-mounted fire extinguishing agent release devices are usually fixed to the corresponding ceiling with multiple sets of bolts, and this installation method has many shortcomings in actual use.

[0005] To address the aforementioned technical problems, this application provides a gaseous fire extinguishing agent release device, comprising a fire extinguishing agent storage tank and a mounting plate. The fire extinguishing agent storage tank is snapped onto the lower end of the mounting plate, and a rod is fixedly installed on the upper end of the fire extinguishing agent storage tank. The upper diameter of the rod is larger than its lower diameter. A slot is formed at the bottom of the mounting plate, and a placement groove is formed above the slot, connecting the slot and the placement groove. The rod is inserted into the slot. A sliding groove is formed through one side of the mounting plate, connecting the sliding groove and the placement groove. The slide plate is internally slidably engaged with a convex groove in the middle of the slide plate. The diameter of the smaller opening end of the convex groove is larger than the smaller diameter of the lower end of the insertion rod, and the diameter of the larger opening end of the convex groove is larger than the larger diameter of the upper end of the insertion rod. The insertion rod is engaged with the upper end of the side with the smaller opening of the convex groove. A spring is fixedly installed at one end of the slide plate, and a connecting plate is fixedly connected to the other end of the spring. A sliding rod is fixedly installed at the other end of the slide plate, and the sliding rod is slidably engaged in the sliding groove. The fire extinguishing agent storage tank is engaged through the cooperation of the insertion rod and the slide plate of the mounting plate.

[0006] In some embodiments, the mounting plate has limit grooves on both sides of the placement groove, and limit sliders are fixedly installed on both sides of the middle part of the slide plate, with the limit sliders slidingly engaging in the limit grooves.

[0007] In some embodiments, a fixing plate is fixedly installed at each of the four corners of the mounting plate, and a screw is threadedly connected to the center of each of the four fixing plates.

[0008] In some embodiments, the lower end of the extinguishing agent storage tank is fixedly connected to an output pipe, the lower end of the output pipe is fixedly connected to a temperature-sensing release component, and a temperature-sensing glass bulb is fixedly installed at the lower end of the temperature-sensing release component.

[0009] In some embodiments, a pressure gauge is provided on one side of the temperature-sensing release component.

[0010] In some embodiments, a signal feedback device is fixedly installed on the other side of the temperature-sensing release component, and one end of the signal feedback device is electrically connected to an electric initiator, wherein the high-heat energy ring of the electric initiator is in direct contact with the temperature-sensing glass ball.

[0011] This application has at least the following beneficial effects:

[0012] 1. This application provides a convenient tank snap-fit ​​and quick-replacement structure. Through the snap-fit ​​mechanism of the plug rod and sliding plate, along with the cooperation of components such as the convex groove and spring, the extinguishing agent storage tank can be quickly installed and disassembled. Compared to traditional bolt connections or other complex fixing methods, this design greatly simplifies the maintenance process. Maintenance personnel can easily remove the storage tank for replacement simply by pressing the sliding rod, improving maintenance efficiency, saving time and labor costs, and significantly enhancing safety.

[0013] 2. In use, this application provides a precise temperature-sensing release and multiple triggering mechanisms. The design of the temperature-sensing release component and the temperature-sensing glass bulb can accurately respond to temperature changes at the fire scene. When the temperature reaches the set value, the temperature-sensing glass bulb breaks, triggering the temperature-sensing release component to open and rapidly spray the extinguishing agent. Simultaneously, the electric initiator and signal feedback device provide another triggering method. It allows for remote control of the electric initiator to generate heat to break the temperature-sensing glass bulb, enabling remote fire extinguishing. It also allows the signal feedback device to send the equipment activation signal back to the control system after the temperature-sensing glass bulb is triggered, achieving multiple triggering and information feedback, thus improving the reliability and flexibility of the fire extinguishing equipment.

[0014] 3. In use, the limiting groove on the mounting plate and the limiting slider on the sliding plate cooperate to provide stable limiting and guiding for the movement of the sliding plate. This structure ensures the accuracy and stability of the sliding plate during movement, allowing the insertion rod to accurately engage with the convex groove, achieving reliable fixing and release of the fire extinguishing agent storage tank. It also ensures the smoothness of the entire locking and releasing process, reducing the risk of failure caused by component shaking or displacement. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0024] Please see Figures 1-6 This application provides a gaseous fire extinguishing agent release device, including a fire extinguishing agent storage tank 1 and a mounting plate 2. The fire extinguishing agent storage tank 1 is snapped onto the lower end of the mounting plate 2. A rod 10 is fixedly installed on the upper end of the fire extinguishing agent storage tank 1. The upper diameter of the rod 10 is larger than the lower diameter. A slot 21 is provided at the bottom of the mounting plate 2. A placement groove 22 is provided above the slot 21 on the mounting plate 2. The slot 21 and the placement groove 22 are connected. The rod 10 is inserted into the slot 21. A sliding groove 23 is provided through one side of the mounting plate 2. The sliding groove 23 is connected to the placement groove 22. A sliding plate 25 is slidably engaged in the placement groove 22. A convex groove 26 is provided in the middle of the sliding plate 25. The diameter of the smaller opening end of the convex groove 26 is larger than the smaller diameter lower end of the insertion rod 10, and the diameter of the larger opening end of the convex groove 26 is larger than the larger diameter upper end of the insertion rod 10. The insertion rod 10 is engaged with the upper end of the smaller opening side of the convex groove 26. A spring 28 is fixedly installed at one end of the sliding plate 25, and a connecting plate 27 is fixedly connected to the other end of the spring 28. A sliding rod 29 is fixedly installed at the other end of the sliding plate 25. The sliding rod 29 is slidably engaged in the sliding groove 23. The fire extinguishing agent storage tank 1 is engaged through the cooperation of the insertion rod 10 and the sliding plate 25 of the mounting plate 2.

[0025] In this embodiment, the extinguishing agent storage tank 1 is engaged with the mounting plate 2 via the upper insertion rod 10. The diameter of the smaller opening end of the convex groove 26 is slightly larger than the smaller diameter lower end of the insertion rod 10, the diameter of the larger opening end of the convex groove 26 is slightly larger than the larger diameter upper end of the insertion rod 10, and the diameter of the smaller opening end of the convex groove 26 is smaller than the larger diameter upper end of the insertion rod 10. In daily use, the lower end of the insert rod 10 with a smaller diameter fits tightly with the side of the convex groove 26 on the sliding plate 25 with a smaller opening. Combined with the continuous tension provided by the spring 28, the connection between the extinguishing agent storage tank 1 and the mounting plate 2 is stable and reliable. When replacing the heptafluoropropane extinguishing agent in the extinguishing agent storage tank 1, simply press the sliding rod 29 to move the sliding plate 25 towards the end closer to the connecting plate 27. During this process, the spring 28 will be compressed, and the side of the convex groove 26 with a larger opening will gradually move closer to the insert rod 10. Since the diameter of the side of the convex groove 26 with a larger opening is slightly larger than the upper end of the insert rod 10 with a larger diameter, the limiting effect on the insert rod 10 and the extinguishing agent storage tank 1 below will be removed. Maintenance personnel can directly remove the extinguishing agent storage tank 1 for replacement. During installation, the insert rod 10 on top of the new fire extinguishing agent tank 1 is aligned with the slot 21 at the bottom of the mounting plate 2 and inserted, and then continuously moved upwards. At this time, the side with the smaller opening of the convex groove 26 in the middle of the sliding plate 25 is directly above the insert rod 10 and will block it, preventing it from moving further upwards. The user only needs to press the sliding rod 29 to move the sliding plate 25 closer to the connecting plate 27, so that the side with the larger opening of the convex groove 26 moves closer to the insert rod 10. At this time, the insert rod 10 can continue to move upwards. When the insert rod 10 touches the top of the mounting plate 2, the limit on the sliding rod 29 is released. Under the action of the spring 28, the side with the smaller opening of the convex groove 26 in the middle of the sliding plate 25 will move closer to the insert rod 10 and be stuck directly below the larger diameter top of the insert rod 10, thereby limiting the entire fire extinguishing agent tank 1. This application completes the disassembly by pressing the sliding rod 29, avoiding maintenance personnel from performing complex operations in a high-altitude working state for a long time, greatly reducing the maintenance difficulty and safety risks, and effectively ensuring the personal safety of maintenance personnel.

[0026] The mounting plate 2 has limit grooves 24 on both sides of the placement groove 22, and the sliding plate 25 has limit sliders 30 fixedly installed on both sides, with the limit sliders 30 slidingly engaged in the limit grooves 24.

[0027] In this embodiment, the limiting grooves 24 opened on both sides of the mounting plate 2 in the placement groove 22 are slidably engaged with the limiting sliders 30 fixedly installed on both sides of the slide plate 25, providing precise and stable guidance for the movement of the slide plate 25 in the placement groove 22, avoiding deviation, jamming or shaking, and ensuring the smoothness and stability of the replacement operation.

[0028] Among them, the four corners of the mounting plate 2 are fixedly installed with fixing plates 20, and the four fixing plates 20 are all threaded with screws.

[0029] The mounting plate 2 is fixedly installed at the four corners of the mounting plate 2. By threading screws into the four mounting plates 20, the mounting plate 2 can be firmly fixed in the required position, ensuring that the entire fire extinguishing equipment is installed stably.

[0030] Among them, the lower end of the extinguishing agent storage tank 1 is fixedly connected to the output pipe 12, the lower end of the output pipe 12 is fixedly connected to the temperature-sensing release component 13, and the lower end of the temperature-sensing release component 13 is fixedly installed with a temperature-sensing glass ball 15.

[0031] The lower end of the extinguishing agent storage tank 1 is connected to a fixed output pipe 12, which delivers the heptafluoropropane extinguishing agent in the storage tank to the temperature-sensing release component 13. The temperature-sensing release component 13 works in conjunction with the temperature-sensing glass bulb 15 fixedly installed at the lower end to accurately sense changes in the surrounding ambient temperature. When a fire occurs and the ambient temperature rises to the rated operating temperature of the temperature-sensing glass bulb 15, the glass bulb breaks, triggering the temperature-sensing release component 13 to open, allowing the extinguishing agent to be rapidly sprayed out through the output pipe 12, thereby extinguishing the fire in a timely manner and effectively ensuring the safety of the protected area.

[0032] The heat-sensing release component 13 is equipped with a pressure gauge 14 on one side. The pressure gauge 14 can display the pressure in the fire extinguishing agent storage tank 1 in real time, so as to determine whether the heptafluoropropane fire extinguishing agent in the fire extinguishing agent storage tank 1 is stored normally or sprayed out for fire extinguishing based on the pressure detected by the pressure gauge 14.

[0033] The heat-sensing release assembly 13 has a signal feedback device 16 fixedly installed on the other side. One end of the signal feedback device is electrically connected to an electric initiator 17, and the high-heat ring of the electric initiator 17 is in direct contact with the heat-sensing glass bulb 15. When the heat-sensing release assembly 13 releases the extinguishing agent, it can promptly send a signal feedback to the fire alarm control system, notifying relevant personnel that the fire extinguishing equipment has been activated. At the same time, the electric initiator 17, which is electrically connected to the signal feedback device 16, provides another activation method because its high-heat ring is in direct contact with the heat-sensing glass bulb 15. When the fire alarm control system detects a fire signal, it can remotely activate the electric initiator 17, causing the high-heat ring to generate heat and quickly break the heat-sensing glass bulb 15, thereby activating the heat-sensing release assembly 13 to release the extinguishing agent. This achieves diversified activation of the fire extinguishing equipment, improves the timeliness and reliability of fire extinguishing, and ensures effective response to fires in various complex situations.

[0034] In addition, a nameplate 11 is affixed to one side of the middle of the fire extinguishing agent storage tank 1, which clearly marks various key information of the storage tank, such as the type of fire extinguishing agent, heptafluoropropane, the capacity of the storage tank, the production date, the service life, the manufacturer, etc., so that maintenance personnel can quickly understand the basic parameters and related information of the equipment by checking the nameplate 11, which facilitates daily maintenance.

[0035] like Figures 1-6As shown, under normal circumstances, the extinguishing agent storage tank 1 is fixed to the sliding plate 25 on the mounting plate 2 by the insert rod 10. The limiting sliders 30 on both sides of the sliding plate 25 are in the limiting grooves 24, ensuring the stability of the sliding plate 25 and thus securing the extinguishing agent storage tank 1. The spring 28 is in its natural state, and the upper end of the insert rod 10 with a larger diameter is engaged with the upper end of the side with a smaller opening of the convex groove 26, restricting the movement of the extinguishing agent storage tank 1. At this time, the heat-sensing glass bulb 15 is not affected by the high temperature and remains intact. The heat-sensing release component 13 is in the closed state. The heptafluoropropane extinguishing agent in the extinguishing agent storage tank 1 is sealed in the tank under normal storage pressure. The pressure gauge 14 displays the normal pressure value, and the signal feedback device 16 and the electric initiator 17 are not triggered. The entire device is in a standby state. When a fire occurs and the ambient temperature rises to the rated operating temperature of the heat-sensing glass bulb 15, the heat-sensing glass bulb 15 will break. This action triggers the opening of the temperature-sensing release component 13, connecting the extinguishing agent storage tank 1 to the outside environment through the output pipe 12. Under the pressure inside the storage tank, the heptafluoropropane extinguishing agent is rapidly sprayed out through the output pipe 12 to extinguish the fire. Simultaneously, after the temperature-sensing release component 13 activates, the signal feedback device 16 sends a signal to the fire alarm control system, informing them that the extinguishing equipment has been activated. Furthermore, if the fire alarm control system detects a fire signal in advance, it can remotely activate the electric initiator 17. The high-heat ring of the electric initiator 17 directly contacts the temperature-sensing glass bulb 15, generating heat that causes the bulb to rupture, thereby triggering the temperature-sensing release component 13 to release the extinguishing agent, achieving remote control activation of the extinguishing process. When it is necessary to replace the heptafluoropropane extinguishing agent in the extinguishing agent storage tank 1, maintenance personnel only need to press the sliding rod 29, moving the sliding plate 25 to the other end of the placement slot 22. During this process, the spring 28 contracts, and the side with the larger opening of the convex slot 26 gradually moves closer to the insertion rod 10. Since the diameter of the larger opening side of the convex groove 26 is slightly larger than the larger diameter upper end of the insertion rod 10, the limiting effect on the insertion rod 10 and the lower extinguishing agent storage tank 1 is removed. Maintenance personnel can directly remove the extinguishing agent storage tank 1 for replacement. After replacement, the sliding rod 29 is released, and under the elastic force of the spring 28, the sliding plate 25 returns to its initial position, re-locking the insertion rod 10, completing the replacement of the extinguishing agent storage tank 1 and the reset of the equipment.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
