[0023] Figure 1This is a schematic diagram of the structure of the present invention;
[0024] The components include: housing 1, first cavity 2, second cavity 3, integrated system 4, nozzle 5, nozzle pipe 6, first pipe section 6a, male interface 6a1, second pipe section 6b, female interface 6b1, fan 7, vacuum generator 8, collection box 9, filter screen 9a, pressure gauge 10, and electric valve 11. Detailed Implementation
[0025] like Figure 1 As shown, the distribution box 1 in this embodiment is equipped with a temperature sensor. The temperature sensor is used to detect the temperature inside the box. There are multiple temperature sensors, and the highest value is taken during detection. The temperature sensor is preferably set at the top of the box 1 and as far away as possible from the electrical components inside the box 1 to avoid damage to them in the event of a fire. If necessary, some fireproof devices can be installed on the temperature sensor.
[0026] The housing 1 has a first cavity 2 and a second cavity 3. The first cavity 2 and the second cavity 3 can be made as a whole with the housing 1, or they can be made as a detachable structure. In this example, the first cavity 2 is a detachable structure with the housing 1, while the second cavity 3 is a whole with the housing 1. The first cavity 2 is located at the bottom of the housing 1, and the second cavity 3 is formed by separating the upper part of the housing 1 with a partition.
[0027] The first cavity 2 is a sealed structure. It contains inert powder and is filled with high-pressure inert gas. The inert powder mainly includes inorganic salts, such as ammonium phosphate, sodium bicarbonate, and sodium chloride, used to extinguish flames. The inert gas is nitrogen or carbon dioxide. The second cavity 3 contains an integrated system 4, which includes a power module, a control module, and a wireless transmission module.
[0028] It also includes a nozzle 5, a nozzle pipe 6, a fan 7, a vacuum generator 8, and a collection box 9. One end of the nozzle pipe 6 connects to the first cavity 2, and the other end of the nozzle pipe 6 passes through the top of the housing 1 and into the housing 1. A pressure gauge 10 and an electric valve 11 are installed on the nozzle pipe 6. The pressure gauge 10 is used to detect whether the pressure of the high-pressure inert gas in the first cavity 2 is maintained at a normal value; if the pressure is too low or too high, maintenance should be carried out promptly. The electric valve 11 is used to control the opening and closing of the nozzle pipe 6. When the electric valve 11 is open, inert powder can be ejected from the nozzle pipe 6 under the drive of the high-pressure inert gas. The pressure gauge 10 and the electric valve 11 should be installed as close as possible to the first cavity.
[0029] In this embodiment, the nozzle pipe 6 includes a first pipe section 6a and a second pipe section 6b. One end of the first pipe section 6a is connected to the first cavity 2, and the other end of the first pipe section 6a is detachably connected to one end of the second pipe section 6b. Specifically, a male interface 6a1 is provided at the other end of the first pipe section 6a, and a female interface 6b1 corresponding to the male interface 6a1 is provided at one end of the second pipe section 6b. The male interface 6a1 and the female interface 6b1 can be plugged in or detached at any time. The other end of the second pipe section 6b passes through the top of the housing 1 and enters the housing 1. Since the second cavity 3 is formed by separating the top of the housing 1 in this embodiment, the other end of the nozzle pipe 6 passes through the second cavity 3 and enters the housing 1 from the top of the housing 1.
[0030] Fan 7 is located at the top inside the housing 1. Fan 7 serves two purposes: firstly, it dissipates heat; secondly, after fire extinguishing, it blows away inert powder, facilitating the vacuum generator 8 to expel the inert powder from the housing 1. In this embodiment, there are two sets of fans 7, each set consisting of two or three fans, positioned on either side of the other end of the nozzle pipe 6 to achieve uniform and sufficient heat dissipation.
[0031] The vacuum generator 8 is equipped with a driver. The air inlet of the vacuum generator 8 enters the housing 1 from the lower part of the side wall, and the air outlet of the vacuum generator 8 enters the collection box 9. The vacuum generator 8 is used to remove heat or inert powder from the housing 1. The collection box 9 is a semi-enclosed structure. A filter screen 9a is installed at the connection point between the collection box 9 and the atmosphere. The filter screen 9a is used to collect inert powder, facilitating its reuse and preventing it from spreading into the atmosphere and affecting other equipment or causing pollution. In this embodiment, the collection box 9 has a cubic or cuboid structure for easy manufacturing. The filter screen 9a is one face of the collection box 9 and is detachably connected to the collection box 9, allowing for cleaning or replacement at any time.
[0032] This embodiment also includes a camera inside the housing 1, used to detect the content of inert powder inside the housing 1. In this embodiment, the camera, electric valve 11, temperature sensor, vacuum generator 8, wireless transmission module, and fan 7 are all connected to the control module. The power module supplies power to the camera, electric valve 11, temperature sensor, vacuum generator 8, wireless transmission module, fan 7, and control module. Additionally, a mobile terminal is included, which is wirelessly connected to the wireless transmission module.
[0033] The specific control steps in this embodiment are as follows:
[0034] S1: When the temperature sensor detects that the temperature of the distribution box is higher than the preset value, it sends a command to the control module;
[0035] S2: The control module controls the electric valve 11 to open, and the inert powder enters the distribution box under the drive of high-pressure inert gas to extinguish the flames;
[0036] S3: When the temperature sensor detects that the temperature of the distribution box is lower than the preset value, it sends a command to the control module again;
[0037] S4: The control module controls the electric valve 11 to close, and simultaneously controls the fan 7, vacuum generator 8 and camera to start;
[0038] S5: When the camera detects that the inert powder content is lower than the preset value, it sends a command to the controller;
[0039] S6: The controller stops the fan 7 and vacuum generator 8 from working and transmits the image captured by the camera to the mobile terminal via the wireless module.
[0040] The IoT-based distribution box provided in this embodiment can extinguish fires that occur inside the distribution box in a timely manner. After the fire is extinguished, it can automatically clean up the inert powder used for fire extinguishing, saving manual cleaning costs and achieving a high degree of automation. It also sends feedback on the cleaned distribution box to a mobile terminal for timely reminders. Moreover, maintenance personnel can check the damage to the distribution box through the mobile terminal, making it easy to quickly prepare the corresponding spare parts and tools for repair without having to go to the site for inspection. This optimizes the maintenance process and improves maintenance efficiency.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
