[0018] 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.

[0019] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0020] Although the spraying mechanism can be activated by sending control commands to an external computer, and the electric control valve opens the fire tank to spray the dry powder inside the cabinet through nozzles to extinguish the fire and prevent the situation from deteriorating further and effectively prevent an explosion, the spraying point is not precise enough during the fire extinguishing operation inside the cabinet. It is necessary to spray the dry powder to completely cover the inside of the cabinet, which will result in a large amount of subsequent cleaning and maintenance work. The practicality needs to be improved.

[0021] In view of this, this utility model discloses a remotely monitored power distribution cabinet. Through the cooperation between the cabinet body, cover plate, mounting bracket, components, wiring box, component box and monitoring unit, when a fire occurs in one of the multiple components installed inside the cabinet during use, the sensor detects the fire signal and uses narrow slit positioning technology to determine the location of the fire source. The signal is transmitted to the components installed inside the component box, and then a command is issued to run the first motor and the second motor. The first lead screw and the second lead screw rotate, moving the nozzle on the front side of the cavity block to the front of the fire element. Then the solenoid valve is energized to open and close, so that the dry powder inside the fire extinguisher is sprayed out through the nozzle, realizing the fire extinguishing operation only on the fire element, making the dry powder spraying point more precise, without having to completely cover the inside of the cabinet with dry powder, thereby reducing the difficulty of subsequent cleaning and maintenance operations.

[0023] In the specific implementation process, it is worth noting that: cabinet 1 is the main body of the power distribution cabinet; cover plate 2 is hinged to cabinet 1 via a hinge; component 4 is the accessory installed inside the power distribution cabinet required for its operation; cable box 5 is used to store the connecting wires required for the operation of this utility model; component box 6 contains the battery, controller, encoder, and other components required for the operation of this utility model; fire extinguisher 7 is a dry powder fire extinguisher; hose 10 is a PU hose of sufficient length to allow for the movement of the cavity block 11; the outer wall of hose 10 is clearance-fitted with the through surface of cover plate 2; the output shaft of the first motor 15 is fixedly connected to the first lead screw 16; the housing of the first motor 15 is fixedly connected to the contact surface of the cavity plate 14; support rod 18 passes through the cavity plate 14 via a transverse groove, allowing the support rod 18 to slide; second lead screw 20 is rotatably connected to support plate 21 via ball bearings; second... The output shaft of motor 22 is fixedly connected to the second lead screw 20. The second motor 22 is fixedly connected to the contact surface of the support plate 21. The outer wall of the upright 23 is clearance-fitted with the second protruding cylinder 24. When a fire occurs in one of the multiple components 4 installed inside the cabinet 1 during use, the sensor 13 detects the fire signal and uses narrow slit positioning technology to determine the location of the fire source. The signal is transmitted to the components installed inside the component box 6. When the command is issued, the first motor 15 and the second motor 22 run, the first lead screw 16 and the second lead screw 20 rotate, causing the nozzle on the front side of the cavity block 11 to move to the front of the igniting component 4. Then the solenoid valve 9 is energized to open and close, so that the dry powder inside the fire extinguisher 7 is sprayed out through the nozzle 12, realizing the fire extinguishing operation only on the igniting component 4, making the dry powder spraying point more precise, without having to completely cover the inside of the cabinet 1 with dry powder, thus reducing the difficulty of subsequent cleaning and maintenance operations.

[0024] Furthermore, a partition plate 27 is provided on the outer side of component 4, and the rear side of the partition plate 27 is fixedly connected to the contact surface of the cabinet 1.

[0025] In the specific implementation process, it is worth noting that the partition 27 can effectively divide the multiple components 4 inside the cabinet 1, which can further reduce the area to be cleaned after the subsequent dry powder fire extinguishing spray.

[0026] Furthermore, an emergency light 29 is installed at the top of the interior of cabinet 1.

[0027] In its implementation, it is worth noting that the working principle of emergency light 29 is as follows: when the power supply is normal, the 220V AC power is stepped down, rectified, and filtered through equipment such as transformers and rectifiers. This power is used to charge the battery and provide daily lighting. When the mains power is suddenly interrupted, the battery in the emergency light will automatically start the inverter circuit to convert the low-voltage energy of the battery into high-voltage energy to drive the light source to continue lighting. At the same time, the relay in the emergency light will lose power, the normally open contact will open, and the normally closed contact will connect the emergency bulb to the battery terminal, providing emergency lighting. In addition, the emergency light should also have an automatic charging protection function, which monitors the battery voltage through a voltage comparator and automatically charges it when the voltage is too low to ensure that the battery is always fully charged. When the mains power is restored, the emergency light will switch back to the mains power supply state and continue to charge the battery for use next time. It can provide lighting for emergency repairs in low-light environments.

[0028] Furthermore, a U-shaped plate 29 is fitted onto the outside of the fire extinguisher 7, and the U-shaped plate 29 is fixedly connected to the contact surface of the cover plate 2.

[0029] In the specific implementation process, it is worth noting that the U-shaped plate 29 can improve the stability of the fire extinguisher 7 after it is placed on the upper surface of the support plate 8.

[0030] Furthermore, the auxiliary unit includes a mesh pocket 25 and a moisture-absorbing paper bag 26. The two mesh pockets 25 are respectively fixed to both sides of the rear surface of the cover plate 2, and multiple moisture-absorbing paper bags 26 are placed inside the mesh pockets 25.

[0031] In the specific implementation process, it is worth noting that the absorbent paper bag 26 is equipped with SAP resin water-absorbing particles inside, which can absorb the moisture in the surrounding environment. It can be replaced regularly to reduce the humidity of the air inside the cabinet 1.

[0032] 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.
