[0025] like Figure 1 and Figure 2 As shown, the energy storage integrated intelligent management and control device disclosed in this embodiment includes an integrated box 1, an electronic control component 2, an air cooling component 3, a liquid cooling component 4 and an impeller assembly 5.

[0026] The integrated box 1 includes a box body 11 , side panels 12 , a box door 13 , a top panel 14 and a rotary locking member 15 .

[0027] The inside of the box body 11 is a cavity, and its two sides, rear side and top are disassembled and respectively equipped with side panels 12, box door 13 and top plate 14. Each component is made of steel material, and the outer layer of the integrated box is coated with corrosion-resistant and rust-proof paint.

[0028] Three side panels 12 are arranged on both sides of the box body. The side panels are hingedly fixed to the inner cavity bottom surface of the box body through connecting pieces and can rotate in a circle along the connecting pieces.

[0029] An inlet and outlet port is provided at the rear side of the box body, and a box door 13 is hingedly provided on the side wall of the inlet and outlet port, and the box door can be opened outwards; a lock is installed on the box door, and the box door can be opened and locked by the lock.

[0030] A top plate 14 is arranged at the top of the box body, and the front end of the top plate is hingedly fixed to the box body by a hinge; a limit strip is arranged at a position of the box body corresponding to the rear end of the top plate, and the rear end of the top plate can be engaged with the limit strip.

[0031] Two rotating locking members 15 are provided at the rear end of the top plate, and the internal lock core can be pushed out by rotation and stuck under the limit strip to fix the top plate. Rotating locking members are also provided at the top center of each side plate, and the lock core can be pushed upward and stuck in the top plate to fix the position of the side plate.

[0032] The side panels, top panel and edge positions of the box body are all fixedly connected with sealing strips, sealing rings and the like to assist in sealing.

[0033] A plurality of electric control components 2 are arranged on the side panel 12, and the electric control components include battery packs, energy storage circulators, battery management systems, communication, monitoring and safety equipment, etc. Each device is fixed by a mounting bracket on the inner wall of the side panel; each device is installed in an embedded manner, and each device is installed on the side panel at a certain distance, with the device on one side facing the gap between the devices on the other side, thereby leaving a large enough space for entry and exit and operation.

[0034] Since each side panel can be opened and closed individually, when each device is installed, a certain length of device wiring needs to be retained to prevent the lines installed on it from being pulled and damaged when the side panels are opened and closed individually.

[0035] like Figure 3 As shown, the air cooling assembly 3 includes a shell 31 , a connecting shaft 32 , a driving motor 33 , suction blades 34 and an air duct 35 .

[0036] The shell 31 is a rectangular parallelepiped shell made of metal, and its surface is covered with air inlet holes at a fixed interval. In addition, multiple layers of filter screens are fixed inside the shell to prevent foreign objects from falling.

[0037] A connecting shaft 32 is provided in the shell, and both ends of the connecting shaft are rotatably connected to the shell through bearings. A driving motor 33 is provided at the head end of the connecting shaft, and spiral suction blades 34 are evenly distributed on the connecting shaft.

[0038] After the driving motor is turned on, it drives the connecting shaft to rotate, and drives the suction blades to rotate, cooperating with the air inlet holes in the shell to suck the hot air flow into the shell.

[0039] The shell and its internal components are arranged at the bottom center of the inner cavity of the box body, coinciding with the position where people walk.

[0040] like Figure 4 As shown, a groove is provided at the front end of the box body 11, and a duct 35 is provided on the left side of the groove. The bottom end of the duct is connected to the head of the shell, and the top of the duct is connected to the top plate. In order to enhance the heat dissipation effect of the duct, multiple layers of heat dissipation fins (not shown in the figure) are designed on its surface.

[0041] like Figure 5 and Figure 6 As shown, the interior of the top plate 14 is a cavity, and a duct frame 141 is provided in the cavity for better distributing the exhaust of the airflow, and an exhaust hole is provided at the bottom end of the top plate corresponding to each duct outlet.

[0042] The air inlet of the conduit rack is connected to the top end of the air duct, a dust fire extinguisher 142 is fixedly connected to the side end of the air inlet of the conduit rack, and a solenoid valve is connected between the dust fire extinguisher and the conduit rack.

[0043] A temperature sensor and a particle sensor are installed in the catheter rack. When the sensor detects that the temperature of the airflow in the catheter rack is higher than the limit value, and the particle sensor simultaneously senses that burning particles are mixed in the airflow, the solenoid valve can be automatically controlled to open.

[0044] like Figure 7 As shown, a deflector plate 143 is provided in each exhaust hole of the conduit frame. The deflector plate includes a grille plate and a fixing rod. The grille plate is disc-shaped and is tiltedly arranged in the exhaust hole. The bottom end of the fixing rod tilts and fixes the grille plate, and the top end thereof is rotatably connected to the conduit frame.

[0045] When the airflow in the pipe frame surges, the grid plate rotates continuously under the action of the airflow. When the airflow is continuously discharged to the external space, the plurality of grid plates form an irregular airflow.

[0046] When the solenoid valve of the dust fire extinguisher is opened, the high-pressure fire extinguishing dust is sprayed out and mixed in the airflow in the duct frame, and follows the grid plate for irregular mixed spraying, which can quickly and efficiently distribute the dust to every space in the box 11, avoiding the disadvantages of the traditional fire extinguishing system's directional injection, thereby preventing the spread of flames to the greatest extent.

[0047] The liquid cooling assembly 4 includes a liquid pipe 41 , a cooling pipe 42 and a heat dissipation pipe 43 .

[0048] The liquid pipe 41 is a square hollow long pipe, buried under the shell 31 in the box. Six openings are respectively arranged at both ends of the liquid pipe, wherein the liquid outlet pipe and the liquid inlet pipe are arranged alternately, and a pair of liquid inlet pipes and liquid outlet pipes correspond to one side plate 12.

[0049] like Figure 8 As shown, each buried plate is provided with a cooling pipe 42. The cooling pipe is a soft tube, and is buried in a U-shaped shape to increase the contact area. The two ends of the cooling pipe are connected to the liquid inlet pipe and the liquid outlet pipe respectively. A total liquid inlet pipe and a total liquid outlet pipe are provided in the liquid pipe 41, which are connected to the cooling pipes connected to each liquid inlet pipe and the liquid outlet pipe respectively.

[0050] The heat dissipation pipe 43 is a U-shaped hollow pipe, the opening of which is downwardly disposed in the groove at the front end of the box body, and the two ends of the heat dissipation pipe are respectively connected to the main liquid inlet pipe and the main liquid outlet pipe.

[0051] Each pipe of the liquid cooling assembly is filled with coolant, which is water mixed with organic solvents to further lower its freezing point. The coolant can effectively dissipate heat in the integrated box.

[0052] like Fig. 9As shown, an impeller assembly 5 is transversely arranged in the heat dissipation pipe and the air duct.

[0053] A driving motor is fixed on one side of the heat dissipation pipe, and the impeller groups in the two pipes are coaxially fixedly connected to the driving motor, which can drive the two impeller groups to rotate synchronously.

[0054] The driving motor drives the two impeller groups to rotate, so that the coolant and air flow in the liquid cooling component and the air cooling component flow in a directional manner; by changing the power and direction of the driving motor, different heat dissipation requirements can be adapted.

[0055] The bottom surface of the groove of the box body is paved with a connecting plate, which is made of copper-aluminum composite material, which has good hardness and good heat exchange capacity. The air duct 35 and the heat dissipation pipe 43 are fixedly connected to the connecting plate to further improve the heat dissipation effect of the two.

[0056] At the same time, an air conditioning compressor is fixed on the connecting plate. The inlet and outlet ends of the air conditioning compressor are connected to the air duct, and the cold air can be directly generated and flowed into the air duct, so that the circulation and heat dissipation effect of the air cooling component is greatly improved.

[0057] When the solenoid valve of the dust fire extinguisher is opened, the operating power of the drive motor will be turned up, thereby accelerating the heat dissipation efficiency and air flow effect, enabling it to complete the fire extinguishing and disaster prevention operations faster.

[0058] The advantages of using this intelligent control device are:

[0059] 1. The original complete box is broken up through the cooperation of the box body, side panels, door, top panel and rotating locks; the box is opened and closed by rotating locks, so as to ensure that a lot of extra space and position can be flexibly changed in the integrated box, which is convenient for maintenance and guarantee; and the box is fixed by rotating locks so that it can be closed into one, so that it can be flexibly transferred and used.

[0060] 2. Through the cooperation of air-cooling components, liquid-cooling components, impeller groups, dust fire extinguisher bottles, and air-conditioning compressors, the interior of the box is effectively cooled. At the same time, the air-cooling components and liquid-cooling components are in contact with each other to dissipate heat, complementing each other and improving the balance of heat dissipation.

[0061] 3. The irregular mixed spraying formed by the deflector plate in the top plate and the dust fire extinguisher bottle can effectively extinguish the internal fire, and has complete fire extinguishing and disaster prevention capabilities.
