Description

Technical Field

[0001] This utility model relates to the field of electrical fire technology, specifically to an insulating fire extinguishing spray structure suitable for electrical fires. Background Technology

[0002] Electrical fires are fires caused by electrical energy. They are mainly caused by the release of heat energy due to electrical circuit or equipment failure (such as short circuits or electric arcs) or the release of heat energy due to non-faulty processes (such as the high-temperature surface of electric heating appliances), which ignites flammable materials. They also include fires caused by lightning and static electricity. They are common in buildings and are accompanied by the risk of electric shock and explosion when fighting them.

[0003] For example, the fire extinguishing sprayer disclosed in Chinese utility model patent CN208694111U includes: a container with a valve and a drive device; wherein the drive device is adapted to extend into the container valve upon triggering to rupture the safety diaphragm, thereby releasing the extinguishing agent in the container from the outlet. This fire extinguishing sprayer stores the extinguishing agent in a container, and the container valve and drive device work together to control its on / off state. Under normal circumstances, the container valve effectively seals the container; when a fire occurs, the drive device can effectively and quickly rupture the safety diaphragm, releasing the extinguishing agent from the outlet.

[0004] When an electrical fire occurs, a fire extinguishing spray structure is needed to extinguish it. However, existing fire extinguishing spray structures can usually only extinguish fires at a fixed and single spray speed during use, and it is difficult to change the spray speed according to the fire situation. This results in poor adaptability and affects the effectiveness of the fire extinguishing spray structure. Summary of the Invention

[0005] The purpose of this invention is to provide an insulated fire extinguishing spray structure suitable for electrical fires, in order to solve the problem mentioned in the background art of the difficulty in changing the fire extinguishing spray speed according to the fire situation of the electrical fire.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an insulated fire extinguishing spray structure suitable for electrical fires, comprising a fire extinguishing spray head for electrical fires, an adjusting component, and a reinforcing component; the fire extinguishing spray head is made of insulating material; the adjusting component is arranged on the fire extinguishing spray head; the adjusting component includes a guide block, an adjusting block, a screw, a limiting groove, and a limiting block; the guide block is fixed on the inner circumferential surface of the fire extinguishing spray head; the adjusting block is slidably disposed on the guide block near the output end of the fire extinguishing spray head via the reinforcing component; the screw is screwed onto the fire extinguishing spray head; a limiting groove is formed on the adjusting block; the limiting block rotatably passes through the limiting groove and is fixedly connected to the screw.

[0007] Preferably, the guide block has an annular structure and the cross-section of the guide block is a right-angled trapezoidal structure, with the inclined surface of the guide block located away from the adjusting block.

[0008] Preferably, the adjusting block has an arc-shaped structure, and the inner diameter of the adjusting block is adapted to the diameter of the guide block.

[0009] Preferably, the limiting block is a T-shaped structure with a smaller upper part and a larger lower part.

[0010] Preferably, the reinforcing component includes a reinforcing groove, a reinforcing block, and a spring; the guide block has a reinforcing groove; the reinforcing block is slidably inserted into the reinforcing groove and fixedly connected to the adjusting block; the two ends of the spring are fixedly connected to the top wall of the reinforcing groove and the top surface of the reinforcing block, respectively.

[0011] Preferably, the reinforcing block has an isosceles trapezoidal structure, and the dimension of the reinforcing block on the side closer to the adjusting block is smaller than the dimension of the reinforcing block on the side farther from the adjusting block, and the shape of the reinforcing block is adapted to the shape of the reinforcing groove.

[0012] Preferably, the diameter of the spring is larger than the size of the side of the reinforcing block furthest from the adjusting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting an adjustment component, installs the fire extinguishing nozzle on the fire extinguishing device. According to the fire situation of the electrical fire, the knob on the screw is rotated to make the screw threadedly connected to the fire extinguishing nozzle, causing the limiting block to rotate in the limiting groove, and the adjusting block to slide on the guide block. The gap between the adjusting block and the guide block gradually increases or decreases until the adjusting block slides to the appropriate position. Since the cross-section of the guide block is a right-angled trapezoidal structure, the guide block can guide the fire extinguishing material (such as carbon dioxide) in the fire extinguishing device, preventing it from accumulating between the guide block and the fire extinguishing nozzle. Compared with the prior art, this utility model has a simple and reasonable structure, ingenious design, and can easily change its fire extinguishing spray speed according to the fire situation of the electrical fire. It has strong adaptability and good use effect.

[0014] 2. By setting up a reinforcing component, when the adjusting block slides on the guide block, the reinforcing block will slide in the reinforcing groove, causing the spring to contract or expand under force. The force generated by the spring can improve the stability of the threaded connection between the screw and the fire extinguishing nozzle, and make the gap between the adjusting block and the guide block more stable. Since the reinforcing block has an isosceles trapezoidal structure, it can improve the stability of the adjusting block on the guide block. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1 to 5 This utility model provides a technical solution: an insulated fire extinguishing spray structure suitable for electrical fires, including a fire extinguishing spray head 1, an adjusting component 2, and a reinforcing component 3; the fire extinguishing spray head 1 is made of insulating material, such as rubber, resin, and plastic (e.g., polytetrafluoroethylene, phenolic plastic); the adjusting component 2 is arranged on the fire extinguishing spray head 1; the adjusting component 2 includes a guide block 201, an adjusting block 202, a screw 203, a limiting groove 204, and a limiting block 205; the guide block 201 is fixedly welded to the inner circumferential surface of the fire extinguishing spray head 1; the adjusting block 202 is slidably disposed on the side of the guide block 201 near the output end of the fire extinguishing spray head 1 through the reinforcing component 3; the screw 202... 03 is screwed onto the fire extinguishing nozzle 1; a limiting groove 204 is provided on the adjusting block 202; the limiting block 205 is rotatably inserted into the limiting groove 204 and fixedly connected to the screw 203; the guide block 201 has an annular structure and the cross-section of the guide block 201 is a right-angled trapezoidal structure, with the inclined surface of the guide block 201 located away from the adjusting block 202; the adjusting block 202 has an arc-shaped structure, and the inner diameter of the adjusting block 202 is adapted to the diameter of the guide block 201, so as to facilitate the adjustment of the flow of fire extinguishing material in the guide block 201 by moving the adjusting block 202; the limiting block 205 has a T-shaped structure with a smaller upper part and a larger lower part, so as to facilitate the connection of the position of the adjusting block 202 and the screw 203.

[0019] This invention, by setting an adjustment component 2, installs the fire extinguishing nozzle 1 on the fire extinguishing device. Depending on the fire situation of the electrical fire, rotating the knob on the screw 203 causes the screw 203 to be threadedly connected to the fire extinguishing nozzle 1, causing the limiting block 205 to rotate within the limiting groove 204. This allows the adjusting block 202 to slide on the guide block 201, gradually increasing or decreasing the gap between the adjusting block 202 and the guide block 201 until the adjusting block 202 slides to a suitable position. Because the guide block 201 has a right-angled trapezoidal cross-section, it can guide the extinguishing agent (such as carbon dioxide) in the fire extinguishing device, preventing it from accumulating between the guide block 201 and the fire extinguishing nozzle 1. Compared to existing technologies, this invention has a simple and reasonable structure, ingenious design, and can easily adjust its extinguishing spray speed according to the fire situation of the electrical fire, exhibiting strong adaptability and good performance.

[0020] As a preferred embodiment, the reinforcing component 3 includes a reinforcing groove 301, a reinforcing block 302, and a spring 303; the reinforcing groove 301 is provided on the guide block 201; the reinforcing block 302 is slidably inserted into the reinforcing groove 301 and fixedly connected to the adjusting block 202; both ends of the spring 303 are fixedly connected to the inner top wall of the reinforcing groove 301 and the top surface of the reinforcing block 302, respectively; the reinforcing block 302 has an isosceles trapezoidal structure, and the size of the side of the reinforcing block 302 near the adjusting block 202 is smaller than the size of the side of the reinforcing block 302 away from the adjusting block 202, and the shape of the reinforcing block 302 is adapted to the shape of the reinforcing groove 301; the diameter of the spring 303 is larger than the size of the side of the reinforcing block 302 away from the adjusting block 202, so as to facilitate the restriction of the position of the spring 303 within the reinforcing groove 301; when the bottom surface of the reinforcing block 302 contacts the inner bottom wall of the reinforcing groove 301, the spring 303 can continue to extend, and there is still a gap between the adjusting block 202 and the guide block 201.

[0021] By setting up a reinforcing component 3, when the adjusting block 202 slides on the guide block 201, the reinforcing block 302 will slide within the reinforcing groove 301, causing the spring 303 to contract or expand under force. The force generated by the spring 303 can improve the stability of the threaded connection between the screw 203 and the fire extinguishing nozzle 1, and make the gap between the adjusting block 202 and the guide block 201 more stable. Since the reinforcing block 302 has an isosceles trapezoidal structure, it can improve the stability of the adjusting block 202 on the guide block 201.

[0022] Working principle: In use, first, install the fire extinguishing nozzle 1 on the fire extinguishing device. Depending on the fire situation of the electrical fire, turn the knob on the screw 203 to connect the screw 203 to the fire extinguishing nozzle 1. This causes the limiting block 205 to rotate within the limiting groove 204, and the adjusting block 202 to slide on the guide block 201. This gradually increases or decreases the gap between the adjusting block 202 and the guide block 201. When the adjusting block 202 slides on the guide block 201, it causes the reinforcing block 302 to slide within the reinforcing groove 301. This causes the spring 303 to contract or expand under force. The force generated by the spring 303 can improve the stability of the threaded connection between the screw 203 and the fire extinguishing nozzle 1, making the gap between the adjusting block 202 and the guide block 201 more stable. After the adjusting block 202 slides to the appropriate position, the guide block 201, with its right-angled trapezoidal cross-section, can guide the extinguishing material (such as carbon dioxide) in the fire extinguishing device, preventing it from accumulating between the guide block 201 and the fire extinguishing nozzle 1.

[0023] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
