[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0036] like Figure 1-Figure 11 As shown, a containerized fireproof energy storage power station of the present invention comprises:

[0037] A box body 1, a row of isolation chambers 11 are installed on one side of the box body 1, and a battery module mechanism 2 is installed together with the box body 1 and the isolation chambers 11;

[0038] The battery module mechanism 2 includes a battery rack 21 arranged inside the box 1, and a plurality of energy storage batteries 22 are placed on the battery rack 21. Four moving wheels are arranged at the bottom of the battery rack 21, and a protrusion 23 is arranged at the bottom of the battery rack 21. The protrusion 23 is passed through by a screw 24 to form a threaded connection. The screw 24 is rotatably installed on the isolation chamber 11 and the inner side of the box 1. The screw 24 is connected to the motor 25 installed on one side of the isolation chamber 11. Pull ropes 26 are connected to both sides of the upper end of the battery rack 21. The pull ropes 26 pass through three sets of pulleys 27 and are connected to a sealing door 28. The sealing door 28 is hinged to the inner wall of the box 1 and is located above the entrance of the isolation chamber 11. The pulleys 27 are respectively located on the inner walls of the box 1 and the isolation chamber 11, and two pulleys 27 are arranged in the isolation chamber 11. The other design is at the top of the inner side of the box 1, close to the isolation chamber 11;

[0039] The isolation chamber 11 and the battery rack 21 are connected with a fire extinguishing assembly 3 for automatic fire extinguishing operation after the battery rack 21 enters the isolation chamber 11 .

[0040] Through the above structural design, when the present invention is in use, the multiple energy storage batteries 22 on the battery rack 21 are used to store electrical energy, and a fire sensor is installed inside the box body 1, and a monitor (both of which are existing conventional designs) is used for monitoring. In the initial state, the sealing door 28 is in an open state and in a horizontal position, and is kept stable by the tension of the pull rope 26. When one or more energy storage batteries 22 on a battery rack 21 are damaged due to a fault or catch fire, the motor 25 on the side wall of the isolation chamber 11 at the position of the battery rack 21 is accurately started by the sensor and the monitor. The driving screw 24 rotates, forcing the battery rack 21 to move into the isolation chamber 11. At the same time, the pull rope 26 loosens the force through the pulley 27, causing the sealing door 28 to rotate and move with the battery rack 21. When the battery rack 21 moves to the corresponding isolation chamber 11, the sealing door 28 is just closed. The isolation chamber 11 and the sealing door 28 use steel plates as structural parts, and the shell is filled with flame-retardant rock wool. The inside and outside are sprayed with fire-retardant paint, so that the energy storage battery 22 located on the battery rack 21 inside it can catch fire without affecting the energy storage batteries 22 of other battery racks 21.

[0041] A counterweight 29 is fixed to the outer wall of the sealing door 28, and the counterweight 29 is located at its lower end when the sealing door 28 is closed.

[0042] Furthermore, through the design of the counterweight block 29, when the battery rack 21 moves to the corresponding isolation chamber 11, the sealing door 28 can rotate downward more smoothly, thereby improving stability.

[0043] The fire extinguishing assembly 3 includes a dry powder box 31 passed through the top of the isolation chamber 11, and two slides 34 are provided at the bottom of the dry powder box 31. A slide plate 33 slides inside the slide 34. The slide plate 33 is connected to the inner wall of the slide by a spring 35, and a toggle piece 36 passing through the slide 34 is provided on one side of the slide plate 33. The toggle piece 36 can be pushed by the translation of a push block 37. The push block 37 is located at the top of the battery rack 21. The slide plate 33 is fixed at the bottom of the square plate 32. The square plate 32 is provided with powder outlet holes corresponding to the dry powder box 31, and the powder outlet holes are distributed in a matrix.

[0044] Through the design of the fire extinguishing component 3, in the initial state, the powder outlet hole of the square plate 32 and the powder outlet hole at the bottom of the dry powder box 31 are misaligned, which plays a blocking role. When the battery rack 21 moves to the corresponding isolation bin 11, the pushing block 37 will contact the toggle piece 36 to push, so that the slide plate 33 overcomes the elastic force of the spring 35 to slide, so that the square plate 32 moves, and the powder outlet holes of the square plate 32 and the dry powder box 31 are aligned. At this time, the dry powder is sprayed out, which can then play a good automatic fire extinguishing effect and prevent the loss from expanding.

[0045] The outer wall of the dry powder box 31 is provided with an annular strapping plate 38, which is placed on the top of the isolation bin 11 and fixed by bolts.

[0046] The design of the annular strap 38 allows the dry powder box 31 to be plug-in installed, which is very convenient to install. The top of the dry powder box 31 is exposed, and the powder adding port can be designed at the top. When adding powder, there is no need to go inside the box 1, which is safer and more convenient.

[0047] Platform 1 110 is installed on the inner wall of the isolation chamber 11, and platform 2 19 is installed on the inner wall of the box body 1. Platform 1 110 and platform 2 19 are at the same height, and the protrusion 23 slides in the openings of platform 1 110 and platform 2 19, while the moving wheels at the bottom of the battery rack 21 roll on the top of platform 1 110 and platform 2 19.

[0048] Through the design of the platform 1 10 and the platform 2 19, the screw rod 24 is located below the platform 1 10 and the platform 2 19, so that the workers can avoid tripping when walking inside the box 1 during inspection, thereby improving safety.

[0049] like Figure 1-Figure 3 as well as Figure 6As shown, a row of wire racks 12 are installed on both sides of one end of the box body 1, and wire racks 12 are provided with wire grooves, and positioning blocks 13 are installed above the wire grooves. Semicircular holes corresponding to the wire grooves are provided at the bottom of the positioning blocks 13, and the wire grooves correspond to the positions of the energy storage batteries 22 one by one. A row of coolant boxes 14 are installed on the outer wall of the box body 1, and a liquid pump 15 is installed on the top of the coolant box 14. An output pipe 16 is installed on the top of the liquid pump 15, and a return pipe 17 is installed on the top of the coolant box 14. One side of the output pipe 16 and the return pipe 17 are provided with conduits passing through the wire rack 12 and the side wall of the box body 1. The outer wall of the box body 1 is provided with multiple rows of wire openings on one side of the wire rack 12 for incoming wires. A heat dissipation pipe 210 passes through the inside of the strap of the battery rack 21. Both ends of the heat dissipation pipe 210 pass through the strap and can be connected to the conduits of the output pipe 16 and the return pipe 17 through a hose, which is a detachable design.

[0050] In the line and heat dissipation optimization design, the line port is used for incoming lines, and then the wires are placed in the wire grooves on the lead frame 12 and docked with the energy storage battery 22. After the docking is completed, the positioning block 13 is installed to fix the line. At the same time, the two ends of the heat dissipation pipe 210 are docked with the conduits of the output pipe 16 and the return pipe 17 through a hose. During daily heat dissipation, the board and heat dissipation pipe 210 of the battery rack 21 are made of heat-conductive materials. The pumping pump 15 is directly started to introduce the cooling liquid in the coolant tank 14 into the heat dissipation pipe 210. The coolant circulates in the heat dissipation pipe 210, effectively absorbing the heat generated by the operation of the energy storage battery 22 on the battery rack 21, and then is guided to the return pipe 17 through the hose, and then flows back to the coolant tank 14, which is very convenient. When the battery fails and catches fire, the battery rack 21 moves into the isolation chamber, and the wires of the energy storage battery 22 and the hoses connected to the cooling can be automatically pulled off by pulling force (through the existing conventional detachable design, which is not limited here), and then the protection work of the isolation chamber 11 is not affected, and automatic power off is also performed.

[0051] A "U"-shaped protective plate 18 is fixed to the outer wall of the box body 1, and the output pipe 16, the return pipe 17 and the wire trough are covered inside. The protective plate 18 can be used for dust prevention and protection, which is very convenient.

[0052] Working principle: First, in the wiring link, the wires are introduced through the multiple rows of wire ports on the outer wall of the box body 1 and are placed in the wire groove of the wire rack 12. After the wires are connected to the energy storage battery 22, the positioning block 13 is installed in place, and the semicircular hole at the bottom cooperates with the wire groove, which not only fixes the wires, but also prevents the wires from loosening or falling off, thereby ensuring the stable transmission of current. Then, the heat dissipation pipe 210 is passed through the inside of the board of the battery rack 21, and can be detachably connected with the output pipe 16 and the return pipe 17 of the coolant tank 14 through a hose. When the energy storage battery 22 starts to work, a certain amount of heat will be generated. At this time, the liquid pump 15 is started, and the coolant in the coolant tank 14 is pumped into the heat dissipation pipe 210 for heat dissipation. Finally, the present invention is also equipped with a complete fire protection The system, once the fire sensor detects a fire, will immediately start the corresponding motor 25, drive the battery rack 11 to move into the isolation chamber, and at the same time, the sealing door 28 is smoothly closed under the action of the counterweight block 29, effectively isolating the battery rack 11 on fire from other battery racks 11, and then, the dry powder in the fire extinguishing component 3 will be quickly sprayed into the isolation chamber to extinguish the fire battery. This series of actions can be completed in a very short time, thereby minimizing the impact of the fire on the energy storage power station. Since the connection between the battery rack 11 and the heat pipe 210 and the wires is a detachable design, the movement of the battery rack 11 will automatically break these connections, thereby realizing automatic power off and separation of the heat dissipation system. It should be noted that an alarm is also installed in the prior art, which will not be elaborated here.

[0053] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
