Description
Technical Field
[0001] The utility model relates to the technical field of charging devices, in particular to an intelligent lithium battery fireproof charging cabinet. Background Art
[0002] With the continuous development of society, electric vehicles have become an important means of transportation for modern people to travel. The reason is that they are energy-saving and environmentally friendly compared with traditional motorcycles, and labor-saving and fast compared with bicycles. Therefore, electric vehicles have absolute advantages compared with traditional means of transportation. However, due to the limitations of electric vehicle battery technology, the existing batteries have poor battery life, long charging time, and fast battery loss. Therefore, it is not enough to meet people's riding needs and brings troubles to people's riding. At present, there are various charging cabinets on the market that can facilitate people to charge electric vehicles.
[0003] At present, incidents of electric vehicle batteries catching fire accidentally during charging are not uncommon. Once the battery catches fire, the fire often spreads rapidly. Since a large amount of heat and harmful gases are released when the battery burns, this not only intensifies the fire but also ignites the surrounding building materials, further expanding the scope of the fire and causing serious casualties and property losses. The existing electric vehicle charging cabinets have obvious deficiencies in safety facilities and lack necessary real-time monitoring and alarm systems and flame retardant facilities. Therefore, when the battery catches fire during charging, the existing charging cabinets cannot issue an alarm in time, let alone take flame retardant measures to control the fire, so the losses caused by the fire cannot be effectively avoided or reduced.
[0004] Therefore, we have developed a new intelligent lithium battery fireproof charging cabinet. Content of the Utility Model
[0005] (1) Technical Problems to be Solved
[0006] Aiming at the deficiencies of the existing technology, the utility model provides an intelligent lithium battery fireproof charging cabinet, which solves the problem that the existing electric vehicle charging cabinets cannot prevent and control in time the fire risk caused by battery ignition in terms of fire safety.

[0009] Preferably, a first electric fire damper is fixedly connected to the bottom of one side of the cabinet body where the electrical box is installed. The first electric fire damper is located at the bottom of the electrical box and is in through communication with the interior of the cabinet body. A second partition net is installed at the penetrating end of the first electric fire damper, and the second partition net is fixedly connected to the inner wall of the cabinet body. Mounting plates are fixedly connected to the opposite surfaces of the inner wall of the cabinet body.
[0010] Through the above technical solution, a first electric fire damper is added to the bottom of the other side of the cabinet body. This fire damper is also located directly below the electrical box vertically. The first electric fire damper is seamlessly connected to the interior of the cabinet body, ensuring rapid response and effective isolation of the fire source in case of an emergency. At the same time, the second partition net at the penetrating end of the first electric fire damper not only enhances the stability of the fire damper but also further refines the protection level, effectively blocking the possible penetration of smoke and fine particles.
[0011] Preferably, a number of shelves are fixedly connected between the mounting plates. A number of fixing holes are fixedly connected to the surface of the mounting plates. The fixing holes are arranged longitudinally. A sensor adjustment bracket is installed on the surface of the mounting plate.

[0012] Through the above technical solution, the fixing holes enable the distance between the shelves to be finely adjusted according to actual needs to accommodate the storage of items of different sizes and weights, improving the flexibility and practicality of the equipment. At the same time, the socket is located at the bottom of the sensor adjustment bracket, facilitating the hiding and arrangement of wires and reducing the risk of accidental electric shock. The design of the fixing bolts sliding through the fixing holes provides a firm fixing method to ensure that the power socket does not fall off during the movement or vibration of the equipment.
[0013] Preferably, a battery temperature induction sensor is fixedly connected between the shelves. One side of the battery temperature induction sensor is fixedly connected to the mounting plate.

The air outlet of the axial flow fan is fixedly connected to the hose, and the air inlet of the axial flow fan is fixedly connected to a first partition net installed on the surface of the top box.
[0020] Through the above technical solution, when the temperature inside the cabinet rises abnormally or a fire hazard is detected, the second electric fire damper can respond quickly and close automatically, effectively preventing the spread of fire. As a bridge connecting the axial flow fan and the second electric fire damper, the selection of the rubber material for the hose not only ensures good flexibility and sealing performance, but also can resist high temperature to a certain extent, increasing the durability and reliability of the system. The design of the rubber hose also takes into account the convenience of installation, allowing flexible layout and adjustment in a limited space. The first partition net set at the inlet of the fan effectively filters the air entering the cabinet, preventing impurities such as dust and sundries from damaging the equipment inside the cabinet and maintaining the cleanliness of the environment inside the cabinet and the normal operation of the equipment.

[0042] Working principle: When the intelligent lithium battery fireproof charging cabinet is in a normal charging state, the intelligent control system integrated inside it monitors the environmental parameters inside the cabinet in real time through diversified sensors such as the smoke sensor 31, the temperature and humidity sensor 14, and the battery temperature sensor 29. These sensors are closely connected to the intelligent PDU 21 to ensure that once any abnormal signals are detected, such as excessive smoke concentration, sharp temperature rise, or abnormal battery temperature, etc., the system will immediately trigger corresponding warning or protection measures. When it is detected that the temperature or smoke concentration inside the cabinet reaches the preset threshold, the intelligent control system will first issue an alarm through the touch display screen 5 and automatically start the fire extinguishing device 15 to release the fire extinguishing agent to quickly extinguish the initial fire source and prevent the spread of the fire. At the same time, the axial flow fan 17 will, in cooperation with the second electric fire damper 16, automatically adjust the ventilation volume to accelerate the circulation and update of the gas inside the cabinet, which helps to reduce the fire and discharge harmful gases. In case of an emergency, users can not only view the real-time data and receive alarm information through the touch display screen 5, but also quickly press the emergency stop button 7 to cut off all power supplies and achieve the internal sealing state of the cabinet through the first electric fire damper and the second electric fire damper, greatly ensuring the absolute safety of the equipment and personnel, and realizing a dual protection mechanism, making the intelligent lithium battery fireproof charging cabinet more calm in dealing with emergencies.
