Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0032] As Figures 1-4 shown, the present invention discloses a fireproof power distribution cabinet, which includes a cabinet body 1 for loading and protecting various electronic components and galvanized bolts 15 for fixedly installing the power distribution cabinet itself. Among them, both ends of the front surface of the cabinet body 1 are rotatably connected with fireproof doors 2 through hinges 9, and the cabinet body 1 and the fireproof doors 2 are made of steel plates not less than 2 mm thick.
[0033] Furthermore, the galvanized bolts 15 are installed on the cabinet body 1 relative to the external structure, and insulating washers 14 are sleeved on the galvanized bolts 15. When installing between the cabinet body 1 and the external structure, the galvanized bolts 15 are used for connection, and insulating washers 14 are sleeved on the galvanized bolts 15, so as to effectively ensure the insulation between the cabinet body 1 and the external structure and effectively protect the normal operation of various electronic component structures inside the cabinet body 1.
[0034] Furthermore, a fixed aerosol fire extinguishing device 12 for extinguishing fires and a thermal wire 13 are installed inside the cabinet body 1, and a smoke alarm 10 for smoke capture and alarm is also installed inside the cabinet body 1.
[0035] As Figures 1-5 shown, a signal transmitter 5 and a relay 6 are installed on one side wall of the cabinet body 1, and the signal transmitter 5, the relay 6, the fixed aerosol fire extinguishing device 12 and the thermal wire 13 are electrically connected. Among them, the signal transmitter 5 is bound to the user's communication device. A combination of a fixed aerosol fire extinguishing device 12 and a thermal wire 13 is provided inside the cabinet body 1. When a fire occurs inside the cabinet body 1, the thermal wire 13 is ignited, triggering the fixed aerosol fire extinguishing device 12 to spray the fire extinguishing agent to implement fire extinguishing. At the same time, the signal transmitter 5 arranged outside the cabinet body 1 sends an abnormal signal to the bound mobile phone, and the signal transmitter 5, the relay 6 and the smoke alarm 10 are also electrically connected.
[0036] Furthermore, a smoke alarm 10 is also provided inside the cabinet body 1. When there is smoke inside the cabinet body 1, the smoke alarm 10 sends a smoke alarm signal. At the same time, the signal transmitter 5 arranged outside the cabinet body 1 sends an abnormal signal to the bound mobile phone.
[0037] As Figures 1-3As shown in the figure, air windows 4 are opened on both side walls of the cabinet body 1. A plurality of air windows 4 are arranged at equal intervals, and their surface area occupies one-half of the outer surface of the cabinet body 1. The large-area air window 4 structure ensures that the inside of the cabinet body 1 is always in a ventilated state, realizes the same temperature inside and outside the cabinet body 1, protects the electronic components from working in a normal temperature environment, and avoids high-temperature situations.
[0038] Furthermore, as Figure 2 shown, shock-absorbing foot pads 7 are installed on the lower surface of the cabinet body 1. When the lower surface of the cabinet body 1 comes into contact with other structures, the shock-absorbing foot pads 7 effectively buffer the contact with the cabinet body 1. The inside of the cabinet body 1 is connected with a load-bearing plate 8 through shock-absorbing blocks 16, and the load-bearing plate 8 is used to load various electronic components.
[0039] Furthermore, a plurality of odor inlets 11 are opened on the outer surface of the smoke alarm 10 for accurately obtaining smoke input.

[0041] The working principle of the present utility model is as follows:
[0042] The power distribution cabinet cabinet body 1 itself is made of a steel plate with a thickness of not less than 2 mm. When it is impacted by the outside world, the cabinet body 1 effectively protects the electronic components inside it. A shock-absorbing block 16 is provided between the load-bearing plate 8 for loading electronic components inside the cabinet body 1 and the cabinet body 1. When the cabinet body 1 is abnormally impacted, the vibration amplitude of each electronic component inside it is further reduced, avoiding the occurrence of a fire due to the impact.
[0043] The combination of the fixed aerosol fire extinguishing device 12 and the thermal sensitive wire 13 provided inside the cabinet body 1. When a fire occurs inside the cabinet body 1, the thermal sensitive wire 13 is ignited, triggering the fixed aerosol fire extinguishing device 12 to spray the fire extinguishing agent to implement fire extinguishing. At the same time, the signal transmitter 5 provided outside the cabinet body 1 sends an abnormal signal to the bound mobile phone.
[0044] When there is smoke inside the cabinet body 1, the smoke alarm 10 sends a smoke alarm signal. At the same time, the signal transmitter 5 provided outside the cabinet body 1 sends an abnormal signal to the bound mobile phone.
[0045] When a fire situation or a smoke alarm situation occurs, the relay 6 cuts off the power supply to protect the cabinet body 1.
