Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, specifically to a closed-type sidewall nozzle for fire fighting. Background Technology

[0002] During lithium-ion battery production, newly produced lithium-ion batteries need to undergo formation and capacity testing in the formation and capacity testing cabinets. However, when there are defective lithium-ion batteries in the products, there is a risk of thermal runaway and fire. Therefore, fire extinguishing systems need to be installed in the storage areas of the formation and capacity testing processes.

[0003] However, traditional closed-type sprinkler nozzles are mostly installed in a pendant manner and are located at the edge of the cabinet, resulting in a limited spray coverage area. Most of the water flow does not reach the protective battery, which greatly reduces the spray flow and intensity, resulting in an unsatisfactory fire extinguishing effect. Therefore, although some existing sidewall-type closed-type sprinkler nozzles have been improved, their water mist coverage is still limited and cannot meet the needs of actual applications. In addition, the existing chemical formation and distribution storage areas use pendant sprinkler heads, which have a large number of nozzles and complex connections, making pipeline construction difficult. Utility Model Content

[0004] This patent provides a fire-fighting closed-wall nozzle with a simple structure and easy installation, aiming to solve the problems of poor fire extinguishing effect and difficult pipeline construction in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a fire-fighting closed-type sidewall nozzle, including a storage compartment. Inside the storage compartment, multiple battery cells are placed through a battery cell tray. The outside of the storage compartment is fixed with a fire-fighting pipe through a bracket and a clamp.

[0006] The fire-fighting pipe is either a U-shaped or an F-shaped structure. At the bends of the U-shaped or F-shaped structure, the fire-fighting pipe is connected to an extension pipe via an elbow. The bottom of the extension pipe is sealed by a pipe end cap, and the nozzle body is vertically connected to one side of the storage location via an installation joint.

[0007] The nozzle body consists of a base frame and a splash plate. The base frame is formed by an integrated connector and a fixing frame. A perforated plate is inserted into the inner side of the connector, and a plug, a temperature sensing element, and a top screw are sequentially arranged from the connector towards the fixing frame. The splash plate has a "7" shaped cross-section and is fitted and fixed to the top of the fixing frame.

[0008] As a preferred technical solution of this utility model, the bracket is set vertically to the storage location, and the outer side of the bracket is fixedly connected to the clamp and the extension pipe at the bottom of the fire pipe by fixing screws.

[0009] As a preferred technical solution of this utility model, the two ends of the U-shaped structure of the fire-fighting pipe are located on both sides of the storage position, and the nozzle body is located on the inner upper side of the storage position.

[0010] As a preferred embodiment of this utility model, the two ends of the F-shaped structure of the fire-fighting pipe are located at the two ends of one side of the storage location, and the nozzle body is located on the inner upper side of the storage location.

[0011] As a preferred embodiment of this utility model, the pipe end cap is either a welded end cap or a threaded end cap.

[0012] As a preferred technical solution of this utility model, one end of the mounting connector is perpendicularly connected to the extension pipe via a tee connector, and the other end is fixedly connected to the nozzle body via a thread.

[0013] As a preferred technical solution of this utility model, the connector is provided with a corresponding fitting opening at the plug, the shape of the plug matches the fitting opening, and a sealing gasket is fitted inside the plug.

[0014] As a preferred embodiment of this invention, the temperature sensing element is provided with metal stripes for sensing the breakage state.

[0015] As a preferred technical solution of this utility model, the set screw is fixedly connected to the top of the fixing frame by a thread, and the set screw and the plug clamp and fix the two ends of the temperature sensing element.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. This fire-fighting closed-wall type nozzle optimizes the complex and redundant design of fire-fighting pipelines in existing chemical container cabinets through targeted pipeline structure and nozzle design, improves spray intensity and coverage area, reduces the number of nozzles used, thereby improving the fire extinguishing effect. Furthermore, by reducing the number of nozzles, the number of key sealing points is reduced, the risk of leakage is reduced, and the fire protection cost per unit is further reduced.

[0027] 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 protection scope of the present utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0029] As per the instruction manual Figure 1-4As shown, a fire-fighting closed-type sidewall nozzle includes a storage compartment 1. Inside the storage compartment 1, multiple battery cells 3 are placed through a battery cell tray 2. On the outside of the storage compartment 1, a fire pipe 6 is fixed by a bracket 4 and a clamp 5. The bracket 4 is set perpendicular to the storage compartment 1, and the outside of the bracket 4 is fixedly connected to the clamp 5 and the extension pipe 8 at the bottom of the fire pipe 6 by fixing screws 20.

[0030] In this utility model, the fire-fighting pipe 6 is either a U-shaped structure or an F-shaped structure. When the fire-fighting pipe 6 is a U-shaped structure, its two ends are located on both sides of the storage position 1, and the nozzle body 11 is located on the upper inner side of the storage position 1, which is suitable for storage positions 1 with a wider width. At the same time, when the fire-fighting pipe 6 is a U-shaped structure, its connection with the external liquid supply channel is located in the middle of the U-shaped structure. When the fire-fighting pipe 6 is an F-shaped structure, its two ends are located at both ends of one side of the storage position 1, and the nozzle body 11 is located on the upper inner side of the storage position 1, which is suitable for storage positions 1 with a longer length.

[0031] In this utility model, the fire-fighting pipe 6 is connected to an extension pipe 8 at the bend of the U-shaped or F-shaped structure via an elbow 7. The bottom of the extension pipe 8 is sealed by a pipe end cap 9, which is either a welded end cap or a threaded end cap, to facilitate sealing and unblocking the end of the pipe. The bottom of the extension pipe 8 is located on one side of the storage position 1 and is vertically connected to the nozzle body 11 via an installation connector 10. One end of the installation connector 10 is vertically connected to the extension pipe 8 via a tee connector 21, and the other end is fixedly connected to the nozzle body 11 via a thread, which changes the angle of the nozzle body 11 and simplifies the installation process of the nozzle body 11.

[0032] As per the instruction manual Figure 5-6 As shown, the nozzle body 11 consists of a base frame 12 and a deflector plate 13. The base frame 12 is formed by an integrated connector 14 and a fixing frame 15. An orifice plate 16 is inserted into the inner side of the connector 14. The flow coefficient of fire water or extinguishing agent is adjusted by the diameter of the holes on the orifice plate 16, thereby further controlling the spray intensity and flow of fire water and extinguishing agent, which has a key impact on the fire extinguishing effect and efficiency. From the connector 14 towards the fixing frame 15, a plug 17, a temperature sensing element 18, and a set screw 19 are arranged in sequence. The set screw 19 is fixedly connected to the top of the fixing frame 15 by threads, and the set screw 19 and the plug 17 clamp and fix the two ends of the temperature sensing element 18. The deflector plate 13 has a "7" shaped cross section and is sleeved and fixed to the top of the fixing frame 15. The position of the deflector plate 13 is the spray end face of the nozzle body 11. Through the guiding effect of the deflector plate 13, the sprayed fire water or extinguishing agent can be guided to the area that needs to be protected, while forming a water mist.

[0033] In this utility model, the connector 14 is provided with a corresponding fitting port 22 at the plug 17. The shape of the plug 17 matches the fitting port 22, and a sealing gasket 23 is fitted inside the plug 17 to seal the orifice plate 16 and prevent fire water or extinguishing agent in the pipeline from flowing out from the orifice plate 16.

[0034] In this invention, the temperature sensing element 18 is provided with metal stripes for sensing the breakage state. When the temperature sensing element 18 breaks due to the breakage temperature, the metal stripes will also break along with the temperature sensing element 18. The broken state of the metal stripes will be transmitted and collected, thereby quickly locating and identifying which nozzle body 11 among many nozzle bodies 11 has been released. It can provide information to the host computer together with the detector in the storage position 1 to determine the accuracy of the spraying of the dedicated closed sidewall type nozzle.

[0035] In a specific implementation of this invention, when the battery experiences thermal runaway and catches fire, the temperature sensing element 18 ruptures at high temperature, and the plug 17 inside the nozzle body 11 is pushed open by the pressure of the fire water or extinguishing agent, releasing the fire water or extinguishing agent; through the guiding effect of the splash plate 13, the sprayed fire water or extinguishing agent is directed to the area that needs to be protected, forming a water mist, thereby achieving comprehensive coverage protection for multiple battery cells 3.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
