Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated substations, specifically to an electrical fire early warning device for prefabricated substations. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor or outdoor power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme. It organically combines the functions of transformer voltage reduction and low-voltage power distribution.

[0003] Currently, in the use of prefabricated substations, fire early warning devices are installed inside the substations to prevent major fire accidents. However, during the early warning process, it is not possible to carry out pre-fire extinguishing work at the fire scene, which may lead to the fire scene getting out of control. To address this issue, we propose an electrical fire early warning device for prefabricated substations. Utility Model Content

[0004] The purpose of this invention is to provide a prefabricated substation electrical fire early warning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated substation electrical fire early warning device, comprising a prefabricated substation room, a fire early warning device fixedly installed inside the prefabricated substation room, and a extinguishing mechanism provided inside the prefabricated substation room. The extinguishing mechanism includes a housing, which is fixedly installed inside the prefabricated substation room. A screw is rotatably connected inside the housing, one end of which is fixedly connected to the end of the shaft of a servo motor. The servo motor is fixedly installed on the outside of the housing, and the outside of the screw is engaged with... A movable plate is connected, and a bracket is fixedly installed on the outside of the movable plate. The bracket is inserted into a limiting groove, which is located on the outside of the box. A connecting pipe is fixedly installed on the bracket. A nozzle is fixedly installed at one end of the connecting pipe, and a flexible hose is fixedly connected to the other end of the nozzle. The flexible hose is positioned on the outside of the box through a limiting component, and the other end of the flexible hose is fixedly connected to a connecting pipe. One end of the connecting pipe is fixedly installed on an air pump. The air pump is connected to a high-voltage box through a branch pipe. The high-voltage box is fixedly installed inside the box-type substation room.

[0006] As a further preferred embodiment of this technical solution, the outer side of the movable plate abuts against the inner wall of the box, and the movable plate is located inside the box.

[0007] As a further preferred embodiment of this technical solution, the outer side of the bracket abuts against the inner wall of the limiting groove, and the bracket is L-shaped.

[0008] As a further preferred embodiment of this technical solution, the connecting pipe and the nozzle are located on one side of the bracket, with the nozzle port facing downwards.

[0009] As a further preferred embodiment of this technical solution, the hose is U-shaped and positioned on the outside of the housing, between the housing and the support.

[0010] As a further preferred embodiment of this technical solution, the limiting component includes a fixing frame, which is fixedly mounted on the outer side of the housing. A flexible tube is inserted into the fixing frame. Two baffles are fixedly mounted on the outer side of the housing, positioned above and below the flexible tube. A pressure plate abuts against the outer side of the two baffles, and the pressure plate is fixedly mounted on the outer side of the support.

[0011] As a further preferred embodiment of this technical solution, rubber strips are fixedly installed on the outer sides of both baffles, and the rubber strips abut against the outer side of the hose.

[0012] This utility model provides a box-type electrical fire early warning device for substations, which has the following beneficial effects:

[0013] This fire early warning device, after detecting and warning of a fire inside a prefabricated substation, drives a servo motor and an air pump to operate. This causes a screw to move a movable plate inside the prefabricated box, allowing the support to move the connecting pipe and nozzle to a position above the fire. Under the action of the air pump, perfluorohexanone inside the high-voltage box is sprayed through the branch pipe, connecting pipe, hose, and connecting pipe, and then sprayed out from the nozzle, thereby extinguishing the fire, reducing the risk of the fire getting out of control, and improving the fire extinguishing capabilities once personnel enter the site.

[0014] This utility model, by setting a limiting component, allows the fixing frame to restrict the position of one side of the hose, while the other side of the hose is positioned between two baffles. This facilitates the movement of the hose by the support, and the rubber strip can push the hose during resetting so that the hose is positioned between the two hoses. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in this embodiment, an electrical fire early warning device for a prefabricated substation includes a prefabricated substation room 1. A fire alarm 2 is fixedly installed inside the prefabricated substation room 1. A fire suppression mechanism 3 is provided inside the prefabricated substation room 1. The fire suppression mechanism 3 includes a housing 4, which is fixedly installed inside the prefabricated substation room 1. A screw 5 is rotatably connected inside the housing 4. One end of the screw 5 is fixedly connected to the end of the shaft of a servo motor 6. The servo motor 6 is fixedly installed on the outside of the housing 4. A movable plate 7 is meshed with the outside of the screw 5. A bracket 8 is fixedly installed on the outside of the movable plate 7. A bracket 8 is inserted into a limiting groove 9, which is located on the outside of the housing 4. A connecting pipe 10 is fixedly installed on the bracket 8. A nozzle 11 is fixedly installed at one end of the connecting pipe 10, and a flexible hose 12 is fixedly connected to the other end of the nozzle 11. The flexible hose 12 is positioned on the outside of the housing 4 by a limiting member, and the other end of the flexible hose 12 is fixedly connected to a connecting pipe 13. One end of the connecting pipe 13 is fixedly installed on an air pump 14, which is connected to a high-voltage box 15 via a branch pipe. The high-voltage box 15 is fixedly installed inside the prefabricated substation room 1. The fire alarm 2 monitors the interior of the prefabricated substation room 1 for fire detection. After disaster detection and early warning, the servo motor 6 and air pump 14 are driven to work, causing the screw 5 to move the movable plate 7 inside the housing 4. This allows the bracket 8 to move the connecting pipe 10 and the nozzle 11 to a position above the fire. Under the action of the air pump 14, perfluorohexanone in the high-pressure box 15 is sprayed out from the nozzle 11 through the branch pipe, connecting pipe 13, hose 12, and connecting pipe 10, thereby extinguishing the fire, reducing the fire's uncontrollability, and improving the fire extinguishing work after personnel enter the scene. The outer side of the movable plate 7 abuts against the housing. On the inner wall of body 4, the movable plate 7 is located inside the box 4 to facilitate the movement of the bracket 8. The outer side of the bracket 8 abuts against the inner wall of the limiting groove 9. The bracket 8 is L-shaped and can move the nozzle 11. The connecting pipe 10 and the nozzle 11 are located on one side of the bracket 8. The nozzle 11 has its port facing downwards, which is effective for fire rescue work. The hose 12 is U-shaped and located on the outer side of the box 4. The hose 12 is located between the box 4 and the bracket 8 so that the bracket 8 can move the hose 12.

[0022] like Figure 3 and Figure 4As shown, the limiting component includes a fixing frame 16, which is fixedly installed on the outer side of the housing 4. A flexible hose 12 is inserted into the fixing frame 16. Two baffles 17 are fixedly installed on the outer side of the housing 4, positioned above and below the flexible hose 12. A pressure plate 19 abuts against the outer side of the two baffles 17, which is fixedly installed on the outer side of the support 8. By providing the limiting component, the fixing frame 16 can restrict the position of one side of the flexible hose 12, while the other side of the flexible hose 12 is positioned between the two baffles 17. This allows the support 8 to easily move the flexible hose 12. Furthermore, the rubber strip 18 can push the flexible hose 12 during resetting, positioning it between the two flexible hoses 12. Rubber strips 18 are fixedly installed on the outer side of each of the two baffles 17, abutting against the outer side of the flexible hose 12. The rubber strips 18 can press and restrict the position of the flexible hose 12.

[0023] This utility model provides a prefabricated substation electrical fire early warning device, the specific working principle of which is as follows:

[0024] During use, the fire alarm 2 can alarm the fire inside the box-type substation 1 and send commands to the servo motor 6 and the air pump 14. That is, the screw 5 drives the moving plate 7 to move inside the box 4, so that the bracket 8 can drive the connecting pipe 10 and the nozzle 11 to move to the position above the fire. Under the action of the air pump 14, the perfluorohexanone in the high-voltage box 15 passes through the branch pipe, connecting pipe 13, hose 12 and the connecting pipe 10 respectively, and is sprayed out from the nozzle 11 to extinguish the fire. During this process, as the bracket 8 drives the hose 12 to move, that is, the upper part of the hose 12 can move to the position between the two baffles 17, and during the reset of the bracket 8, the pressure plate 19 can squeeze and push the outside of the hose 12, so that the hose 12 can be tightly attached to the outside of the rubber strip 18.

[0025] 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.
