As a further preferred embodiment, the fire fighting material in the fire fighting equipment is preferably liquid carbon dioxide, and the pipeline outlet at the top of the fire fighting equipment is located in the internal cavity where the pointed structure is located, e.g. the wall where the outlet is located opposite the pointed structure. Preferably, an orifice plate structure (not shown in the figure) can be installed between the inner cavity of the pointed structure and the square cavity below the pointed structure, the orifice plate structure is of multiple layers, for example, two layers, the orifices in the orifice plate structure are staggered, and the sizes of the orifices are adjusted and set by a person skilled in the art according to actual conditions. The arrangement has the advantages that when fire or smoke occurs, the smoke is not influenced to be gathered upwards, and after the fire-fighting equipment is started, the sprayed carbon dioxide with certain pressure cannot directly or indirectly impact on structures such as the lower electric switch 2 and the like at high speed. Preferably, the pipeline outlet enters the internal cavity in a tangential inlet mode, so that the direct impact effect of the sprayed high-pressure carbon dioxide on the electric switch and the electric lead wire can be reduced, the fluid buffering effect is achieved by impacting the side wall of the distribution box, and if only a small area of fire or only a local high temperature (for example, the local high temperature can be higher than 70 ℃) without generating open fire occurs, the rest switches of the distribution box cannot be damaged and the whole distribution box is replaced after fire extinguishment.
Further preferably, when the tangential inlet is adopted, a non-aerosol fire extinguishing sticker is further attached to the surface of the inner cavity at the position of the pointed structure on the back side (the outlet flow direction is taken as the front side, and the back side refers to the side opposite to the outlet flow direction) of the pipeline outlet. The arrangement has the advantages that under normal conditions, if high temperature (for example, the temperature reaches 70 ℃ and is specifically set according to needs) or smoke (at the moment, fire is not generated or the fire is in the initial stage) is detected, the system can directly start the carbon dioxide fire-fighting equipment to carry out fire-fighting treatment, so that the non-aerosol fire-fighting paste is not needed, and the sprayed carbon dioxide can not impact the non-aerosol fire-fighting paste; if the carbon dioxide fire-fighting equipment fails to work and the like, the internal combustion of the distribution box burns, and when the temperature of the fire-extinguishing paste reaches the starting point temperature (which is generally 110 ℃ at the lowest), the non-aerosol fire-extinguishing paste plays a fire-fighting role.
Preferably, various electrical switches are disposed in the distribution box body 5, including a main switch and a branch switch (e.g., a lighting switch, an air conditioner switch, etc.), and at least one temperature detection device 3 is mounted on an electrical conductor connected to each electrical switch.
Further preferably, the liquid carbon dioxide fire-fighting equipment is arranged on one side far away from the main switch, and the distribution box body 5 on one side close to the fire-fighting equipment is made of a heat insulating material.
In addition, when the electric lead 4 is connected with the electric switch 2, the electric lead 4 is usually inserted into a connection hole of the electric switch 2, and the electric conduction is realized by screwing, and the tightness degree of the connection is a main factor influencing the size of the connection resistance at the position, if the connection is poor, the connection resistance is large (which may be caused by long-term thermal expansion and cold contraction, and the like), electric arcs are easy to appear at the position, and fire is caused, so as to refer to fig. 4-5, the invention also provides a further preferable embodiment, that is, the tail end of the connection screw of the electric switch 2 adopts the structure shown in fig. 4, the middle part of the tail end of the connection screw is provided with a cylindrical groove structure, the tail end of the connection screw is made of an alloy material which is not easy to expand when heated, and the cylindrical groove structure is tightly provided with an alloy material which is easy to expand when heated (such as Cu60Zn40 and the like, which have a larger expansion coefficient). Referring to fig. 5, when the temperature of the wiring is high, the alloy material which is easy to expand when heated in the cylindrical groove structure expands, and the alloy material is limited by the alloy material which is not easy to deform at the outer side and extends along the axial direction, so that the screw is always pressed on the electric wire, the risk of electric arc generation is reduced, and the occurrence probability of fire is reduced. It should be understood that the above-mentioned electric well is an electric well that is upstream of the electric distribution box and is closer to the electric distribution box.
The working principle of the intelligent fire prevention system for the distribution box is as follows:
during normal operation, the first communication unit of the MCU device 102 communicates with the wireless communication modules attached to the optical smoke sensor 1 and the temperature detection device 3 of the distribution box part in real time through a dedicated network to obtain initial data from the optical smoke sensor 1 and the temperature detection device 3, and the initial data is processed by the microprocessor unit; the first communication unit is also connected to the internet cloud end through a GPRS network, a GSM network or a local area network communication network (preferably a wifi network), and part of data processed by the micro-processing unit is transmitted to the cloud end through the first communication unit;
in the monitoring process, if the detected value of any one of the optical smoke sensor 1 and the temperature detection device 3 reaches a preset threshold value (for example, the temperature is higher than 70 ℃), the micro-processing unit of the MCU device sends a power-off instruction to the electric well central processing unit, the electric well central processing unit starts the switch module to perform electric well power-off operation according to corresponding initial data information, after power-off, the electric well central processing unit sends power-off feedback to the micro-processing unit, the micro-processing unit starts the power-off reminding module to perform power-off alarm, the micro-processing unit then performs source tracing analysis by means of data information stored in the first communication unit and calls data of the cloud terminal chain to obtain the position with abnormal circuit, displays the abnormal position through a display screen of the power-off reminding module, and simultaneously starts the execution module, opens the electromagnetic valve 6 arranged on a corresponding pipeline of the corresponding fire-fighting equipment, and releases fire-fighting materials such as carbon dioxide. In the process, if the temperature of the connection position of the electric lead 4 and the electric switch 2 rises (higher than normal temperature, the expansion and deformation of the heated easily-expandable material are larger along with the rise of the temperature), the heated easily-expandable alloy material arranged in the cylindrical groove structure at the tail end of the wiring screw of the electric switch expands to extrude the electric lead, so that electric arcs or electric sparks are avoided;
the distribution box is also provided with a non-aerosol fire extinguishing paste, and if the fire extinguishing paste is burnt in the distribution box under special conditions such as failure of carbon dioxide fire-fighting equipment and the like, the non-aerosol fire extinguishing paste plays a fire fighting role when the temperature of the position of the fire extinguishing paste reaches the starting point temperature (generally reaching 110 ℃ at the lowest at present).
