Description

Technical Field

[0001] This utility model belongs to the field of fire extinguisher technology, and in particular relates to a suspended temperature-sensing fire extinguisher. Background Technology

[0002] In the field of fire safety, fire extinguishers are an important type of fire-fighting equipment, widely used in fire prevention and initial fire suppression in various locations. Traditional fire extinguishers are mostly portable or wheeled, requiring operators to approach the fire source at close range to extinguish it, which poses a significant safety hazard in some high-temperature, toxic, or difficult-to-access fire scenes.

[0003] With the continuous development of fire protection technology, suspended fire extinguishers have gradually attracted people's attention. Suspended fire extinguishers can be installed above the area that needs protection and automatically activate the extinguishing procedure by sensing signals such as temperature or smoke, without requiring operators to be close to the fire source, thus improving the safety and efficiency of fire extinguishing.

[0004] However, existing suspended fire extinguishers still have shortcomings in terms of extinguishing agent coverage and spray uniformity. Some suspended fire extinguishers spray the extinguishing agent only through a nozzle in a single direction, resulting in a limited coverage area and difficulty in quickly controlling the spread of fire. At the same time, due to the lack of a mechanism to promote uniform spraying of the extinguishing agent, uneven distribution of the extinguishing agent may occur during spraying, affecting the fire extinguishing effect.

[0005] Therefore, it is necessary to develop a new type of suspended temperature-sensitive fire extinguisher.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to provide a suspended temperature-sensitive fire extinguisher. Through the design of the nozzle and the mounting base installed via bearings, the coverage of the extinguishing agent can be expanded, the uniformity of spraying can be improved, and thus the spread of fire can be controlled more effectively, ensuring the safety of people and property.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a suspended temperature-sensitive fire extinguisher, comprising a tank with an outlet pipe and a nozzle connected to the outlet pipe, and a fire extinguishing agent contained in the tank; the nozzle includes a nozzle body, a temperature-sensitive glass bulb, a sealing seat, and a support wire; a suspension rod is provided at the upper end of the tank; the suspension rod is rotatably mounted on a mounting seat via a bearing; a branch output hole is provided on the outer wall of the nozzle body, which is tangentially connected to its inner cavity; when the temperature-sensitive glass bulb, the sealing seat, and the support wire are installed on the nozzle body, the sealing seat closes the branch output hole.

[0009] As a preferred embodiment of this utility model, a conduit is fixedly connected to the outlet pipe; a pressure gauge is installed at the end of the conduit.

[0010] As a preferred embodiment of this utility model, a filling pipe is fixedly connected to the outlet pipe; a valve body is installed on the filling pipe.

[0011] As a preferred embodiment of this utility model, the mounting base includes an open circular groove that mates with the outer ring of the bearing; a through hole is provided at the lower end of the circular groove that mates with the suspension rod; a retaining ring groove is provided on the outer wall of the suspension rod, and the retaining ring groove is positioned above the bearing; a retaining ring is installed on the retaining ring groove; and a flange is fixed at the upper end of the circular groove.

[0012] As a preferred embodiment of this invention, the extinguishing agent is heptafluoropropane.

[0013] This utility model has the following beneficial effects: This invention, by incorporating tangential branch outlet holes on the nozzle body, allows a portion of the extinguishing agent to be sprayed horizontally outward, thereby expanding the coverage area of ​​the extinguishing agent and improving extinguishing efficiency. The extinguishing agent sprayed from the branch outlet holes exerts a rotational tangential reaction force on the tank body. With the mounting base and tank body rotated via bearings, the tank body begins to rotate, resulting in a more uniform distribution of the extinguishing agent in the main spray direction, a larger side spray coverage area, and further accelerating the coverage rate of the extinguishing agent.

[0014] This utility model features an ingeniously designed mounting base, including a circular groove that mates with the outer ring of the bearing, a through hole that fits with the clearance of the suspension rod, and a retaining spring to prevent detachment, ensuring the stability of the mounting base. Simultaneously, a flange is fixed to the upper end of the circular groove, facilitating the fixing of the fire extinguisher to a wall or other supporting structure, making installation convenient and quick.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific Implementation Example 1: Please refer to... Figure 1-4 As shown, this utility model is a suspended temperature-sensitive fire extinguisher, including a tank 1 with an outlet pipe 11 and a nozzle connected to the outlet pipe 11, and a fire extinguishing agent contained in the tank 1. The nozzle includes a nozzle body 3, a temperature-sensitive glass bulb 4, a sealing seat 5, and a support wire 6. A suspension rod 12 is provided at the upper end of the tank 1. The suspension rod 12 is rotatably mounted on a mounting base 2 via a bearing. A branch output hole 31 is opened on the outer wall of the nozzle body 3, which is tangentially connected to its inner cavity. When the temperature-sensitive glass bulb 4, the sealing seat 5, and the support wire 6 are installed on the nozzle body 3, the sealing seat 5 closes the branch output hole 31.

[0024] In practical applications, the working principle and advantages of this suspended heat-sensing fire extinguisher are as follows: When a fire occurs, the temperature reaches the rupture temperature of the heat-sensing glass bulb 4, causing it to rupture. The sealing seat 5 is then discharged under pressure, and the high-pressure extinguishing agent sprays downwards onto the main spray nozzle 3, splashing outwards from the splash plate below the nozzle body 3. Part of the extinguishing agent is sprayed horizontally outwards from the two tangentially positioned branch outlet holes 31, increasing the extinguishing agent's deployment range. Through the tangentially positioned branch outlet holes 31, the extinguishing agent not only sprays downwards but also diffuses horizontally, significantly increasing the coverage area and improving extinguishing efficiency. Furthermore, it promotes tank rotation, making the main spray more uniform: the extinguishing agent sprayed from the branch outlet holes 31 provides a tangential reaction force to the tank body 1. Since the mounting base 2 and the tank body 1 are mounted via bearings, the tank body 1 begins to rotate under this reaction force. This rotation makes the extinguishing agent distribution in the main spray direction more uniform, and the side spray coverage larger, further accelerating the extinguishing agent coverage rate.

[0025] The outlet pipe 11 is fixedly connected to a conduit 14. A pressure gauge 7 is installed at the end of the conduit 14 to monitor the pressure inside the tank 1 in real time, ensuring that the fire extinguisher is within its normal operating range.

[0026] The outlet pipe 11 is fixedly connected to a filling pipe 15. A valve body 8 is installed on the filling pipe 15 to facilitate rapid filling after the extinguishing agent is used up, thereby improving the reusability of the fire extinguisher.

[0027] The mounting base 2 includes an upper-opening circular groove 21 that mates with the outer ring of the bearing. The lower end of the groove 21 has a through hole 22 that fits with the suspension rod 12, ensuring the mounting base 2 can be stably installed on the suspension rod 12. The outer wall of the suspension rod 12 has a retaining spring groove 13, positioned above the bearing, and fitted with a retaining spring 9 to prevent the mounting base 2 from falling off. A flange 23 is also fixed to the upper end of the groove 21, facilitating the fixing of the fire extinguisher to a wall or other supporting structure.

[0028] In this embodiment, the extinguishing agent is heptafluoropropane. It has advantages such as high extinguishing efficiency and low environmental impact, and is suitable for fire fighting in various locations.

[0029] One specific application of this embodiment is as follows: the suspended heat-sensing fire extinguisher is fixed above the location requiring protection, such as a data center or warehouse, via the mounting base 2. In the event of a fire, the fire extinguisher will automatically sense the temperature and initiate the extinguishing procedure, quickly covering the fire source and effectively controlling the spread of the fire.
