Description

Technical Field

[0001] This utility model relates to the field of power distribution protection technology, and in particular to an automated protection device for emergency repair of power distribution networks. Background Technology

[0002] Chinese patent document CN209747960U discloses an automatic protection device for emergency repair of power distribution networks. The protection device includes a distribution cabinet and a cabinet door. The cabinet door is connected to one side of the distribution cabinet via a hinge. A vent pipe is inserted into the top of the inner cavity of the distribution cabinet. One end of the vent pipe is connected to a gas collection hood via a snap-fit. An exhaust fan is connected to the inside of the gas collection hood via screws. A mounting shell is provided on the top of the distribution cabinet. A wireless smoke alarm is detachably connected inside the mounting shell. A platform is fixedly connected to the inner wall of the mounting shell. A protruding post is integrally formed on the upper surface of the platform. The wireless smoke alarm is installed outside the distribution cabinet without affecting the transmission of the wireless signal. When the wireless smoke alarm is triggered, it transmits the alarm to the host via a wireless protocol. The host uploads the data to a cloud server, and then the cloud server pushes the information to the backend, which then quickly dispatches power maintenance personnel for repair.

[0003] However, when the above-mentioned devices are damaged and burn, they can only sound an alarm and wait for staff to come to repair them. During this process, the fire cannot be stopped in time, which can easily spread the fire or even cause a fire. The automatic protection effect of the device is poor. Therefore, we propose an automated protection device for emergency repair of power distribution networks. Utility Model Content

[0004] The purpose of this utility model is to provide an automated protection device for emergency repair of power distribution networks, which solves the problem that some existing devices cannot automatically protect against fire in a timely manner.

This achieves effective automatic protection and solves the problem that some existing devices can only sound an alarm and wait for staff to repair when the components are damaged and burning. During this process, the fire cannot be stopped in time, which can easily spread the fire or even cause a fire. The automatic protection effect of the device is poor, which improves the use effect of the device.

[0016] (2) The power distribution network emergency repair automation protection device, through the cooperation of the radiator and the smoke alarm, can dissipate heat inside the distribution cabinet during normal operation, and when a fire occurs inside the distribution cabinet, it can promptly deliver the smoke to the smoke alarm to realize a rapid alarm, provide feedback to the staff, and drive the fire extinguishing mechanism to operate, thus ensuring the effectiveness of the device and facilitating its promotion and use.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: an automated protection device for emergency repair of power distribution networks, including a distribution cabinet 1 and a fire extinguishing mechanism 2. A circular opening 3 is provided through the top of the distribution cabinet 1. A radiator 4 is fixedly installed on the top of the distribution cabinet 1. The input end of the radiator 4 communicates with the interior of the distribution cabinet 1 through the circular opening 3. A smoke alarm 5 is installed directly above the radiator 4. Two sets of fixing rods 6 are fixedly installed on the outer surface of the smoke alarm 5. One end of each set of fixing rods 6 is fixedly connected to the top of the distribution cabinet 1. A safety device is fixedly installed between the inner walls of both sides of the distribution cabinet 1. Mounting plate 7 has at least two sets of mounting holes 8 through it. A collection tray 9 is placed on the bottom inner side of the distribution cabinet 1. Two sets of mounting plates 10 are fixedly installed on the top and bottom of the distribution cabinet 1. With the cooperation of radiator 4 and smoke alarm 5, the internal parts of the distribution cabinet 1 can be cooled during normal operation. When a fire occurs inside the distribution cabinet 1, the smoke can be delivered to the smoke alarm 5 in time to realize a rapid alarm, feedback to the staff, and drive the fire extinguishing mechanism 2 to operate, ensuring the effectiveness of the device and facilitating its promotion and use.

[0024] Fire extinguishing mechanism 2 is installed on distribution cabinet 1. Fire extinguishing mechanism 2 includes placement cylinder 21, storage bottle 22, docking interface 23, hose 24, docking sleeve 25 and solenoid valve 210. Placement cylinder 21 is fixedly installed on one outer surface of distribution cabinet 1. Storage bottle 22 is placed inside placement cylinder 21. The top of storage bottle 22 is integrally formed with docking interface 23 communicating with its interior. Hose 24 is fixedly installed on one outer surface of distribution cabinet 1. Docking sleeve 25 is rotatably installed at one end of hose 24. Docking sleeve 25 is threaded onto docking interface 23. Solenoid valve 210 is installed on hose 24.

[0025] The fire extinguishing mechanism 2 also includes a hollow ring 26, a fixing plate 27, a connecting pipe 28, and nozzles 29. A hollow ring 26 is installed inside the distribution cabinet 1. A set of fixing plates 27 is fixedly installed between the hollow ring 26 and each of the two inner walls of the distribution cabinet 1. A connecting pipe 28 communicating with the interior of the hollow ring 26 is fixedly installed on the top of the hollow ring 26. One end of the connecting pipe 28 is fixedly connected to one inner wall of the distribution cabinet 1 and communicates with a flexible hose 24. At least two sets of nozzles 29 communicating with the interior of the hollow ring 26 are fixedly installed on the bottom of the hollow ring 26. Through the fire extinguishing mechanism 2, the fire in the distribution cabinet 1... Equipped with a storage bottle 22, when a fire occurs in the distribution cabinet 1, the solenoid valve 210 is opened in time, allowing carbon dioxide to enter the hollow ring 26 through the hose 24 and connecting pipe 28, and be sprayed in a dispersed manner from each nozzle 29 onto the components for fire extinguishing, achieving effective automatic protection. This solves the problem that some existing devices can only sound an alarm and wait for staff to repair when components are damaged and burning, during which the fire cannot be stopped in time, which can easily spread the fire or even cause a fire, resulting in poor automatic protection effect of the device, thus improving the use effect of the device.

[0026] Working principle: The components are installed on the mounting plate 7 through the mounting holes 8. During normal operation, the heat sink 4 is activated to dissipate heat from the distribution cabinet 1. When a component catches fire, the heat sink 4 will blow the smoke to the smoke alarm 5 immediately to trigger an alarm and notify the staff to prepare for emergency repairs. At the same time, it will control the solenoid valve 210 to open, and the carbon dioxide in the storage bottle 22 will enter the hollow ring 26 through the hose 24 and connecting pipe 28, and be dispersed from each nozzle 29 onto the component to extinguish the fire. When the staff arrives to clean up, the collection tray 9 collects various wastes, and after completion, it can be taken out and emptied.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
