Safety isolation frame for secondary use of power lithium battery energy storage power stations

Abstract

This invention discloses a safety isolation frame for a cascaded utilization power lithium battery energy storage power station, comprising: a fixed isolation chamber in which a lithium battery is movably disposed; and a pushing and fixing mechanism, which includes a base plate movably disposed within the fixed isolation chamber and several pushing plates; the lithium battery is driven to move onto the base plate and is pushed. The safety isolation frame for a cascaded utilization power lithium battery energy storage power station provided by this invention allows the lithium battery to be placed in the fixed isolation chamber during installation. Since the space within the fixed isolation chamber is larger than the size of the lithium battery, the lithium battery can be easily placed in without needing to be aligned with the fixed isolation chamber. After the lithium battery is placed on the base plate, its own weight presses against the base plate, causing it to slide and drive the pushing plates closer to and ultimately into contact with the lithium battery. Simultaneously, it pushes the lithium battery to the center of the fixed isolation chamber to facilitate subsequent processes such as battery docking, without requiring additional fasteners for fixation.

Description

Technical Field

[0001] This invention relates to the field of isolation frame technology, and more specifically to a safety isolation frame for a cascaded power lithium battery energy storage power station. Background Technology

[0002] Energy storage power stations store recyclable electrical energy, such as that from wind power or hydroelectric power plants, through batteries. This helps regulate peak and off-peak electricity demand. Safety barriers are installed within energy storage power stations to protect the batteries by separating them.

[0003] Lithium batteries have high energy storage capacity per unit volume, making them suitable for energy storage power stations. However, lithium batteries are prone to thermal runaway due to overheating, overcharging, internal short circuits, and collisions. Thermal runaway includes three stages: the self-heating stage (50℃-140℃), the thermal runaway stage (140℃-850℃), and the thermal runaway termination stage. During the thermal runaway stage, lithium batteries can generate heat and spontaneously combust, which is difficult to control and can easily lead to spontaneous combustion or a chain explosion.

[0004] According to patent number CN202111438386.0, published on February 18, 2022, a battery accident alarm and isolation mechanism for an energy storage power station is disclosed, mainly relating to the field of energy storage power stations. The mechanism includes a frame with multiple layers of mounting cavities. Protruding triangular wing plates are provided on both sides of each mounting cavity. Slide grooves are provided on both the front and rear sides of the frame, with sliding rods slidably mounted within the grooves. A folding plate is hinged to the top of each mounting cavity. Sliding blocks, hinged to both sides of the front plate and slidably connected to the slide grooves, are fixedly connected to the sliding rods and sliding blocks. Telescopic power mechanisms are provided on both sides of the top of the frame. Several temperature sensors and smoke detectors are installed inside the frame. A gas tank is installed on one side of the frame, with a solenoid valve connected in series between the gas tank's outlet and a pipeline. The beneficial effect of this invention is that it isolates battery accidents in energy storage power stations by isolating oxygen, thereby reducing economic losses caused by battery explosions.

[0005] In the prior art, including the aforementioned patents, the frame is mostly equipped with slots to fix the lithium battery. When the slot size is larger than the lithium battery, it is convenient to install the lithium battery, but additional fasteners are needed to prevent the lithium battery from shaking. When the slot size is close to the lithium battery, it can prevent the lithium battery from shaking, but the reserved gap is small and it is inconvenient to put the lithium battery in. Summary of the Invention

[0006] The purpose of this invention is to provide a safety isolation frame for a cascaded power lithium battery energy storage power station, which aims to solve the problem that large-sized slots, which are easy to install, can cause lithium batteries to shake.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a safety isolation frame for a cascaded utilization power lithium battery energy storage power station, comprising:

[0008] A fixed isolation chamber, in which lithium batteries are dynamically installed;

[0009] The pushing and fixing mechanism includes a base plate and several pushing plates that are movably disposed within the fixed isolation chamber;

[0010] The lithium battery is driven to move onto the base plate and push against it, thereby causing the push plate to adhere to and lock the lithium battery.

[0011] Preferably, the pushing and fixing mechanism further includes a movable main flipping rod, and the bottom support plate is driven to move so as to drive the main flipping rod to flip and push a plurality of the pushing plates to adhere to the lithium battery.

[0012] Preferably, a testing organization is also included, the testing organization comprising:

[0013] The auxiliary rotating rod is rotatably connected to the main rotating rod;

[0014] A counterweight locking block is used to lock the bottom support plate;

[0015] The push plate is driven away from the lithium battery to cause the auxiliary rotating rod to flip and drive the counterweight lock block to unlock the bottom plate.

[0016] Preferably, the push plate is provided with shape memory plastic, which deforms when heated to drive the push plate away from the lithium battery.

[0017] Preferably, the auxiliary rotating rod is provided with a pulling rope for pulling the counterweight lock block to unlock the bottom support plate.

[0018] Preferably, the base plate is driven to spring up, thereby driving the plurality of push plates away from the lithium battery.

[0019] Preferably, the system also includes a ventilation component, which comprises:

[0020] An air guide channel is provided on the push plate and is fixedly connected to the outside.

[0021] The memory plastic seals the air passage.

[0022] Preferably, the ventilation assembly further includes a ventilation tube, which is used to fixally connect to the air extraction unit, and the air guide channel is movably connected to the ventilation tube.

[0023] Preferably, the lithium battery is provided with a power interface, the fixed isolation compartment is provided with a power connection slot, and the bottom plate is driven to move so as to make the power interface and the power connection slot either connected or disconnected.

[0024] Preferably, the push plate is provided with a fixing post, the center point of the memory plastic is located at the fixing post, and the memory plastic deforms in a bulging shape along the fixing post when heated.

[0025] In the above technical solution, the safety isolation frame of the cascade utilization power lithium battery energy storage power station provided by the present invention has the following beneficial effects: During installation, the lithium battery is placed in the fixed isolation compartment, and the space inside the fixed isolation compartment is larger than the size of the lithium battery. At this time, the lithium battery can be easily placed in without aligning it with the fixed isolation compartment. After the lithium battery is placed on the bottom support plate, the weight of the lithium battery itself presses the bottom support plate to slide it, thereby driving several push plates to approach the lithium battery and finally fit together to play a fixing role. At the same time, it will also push the lithium battery to the center of the fixed isolation compartment to facilitate subsequent processes such as connecting the lithium battery, and no additional fasteners are required for fixation.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0043] like Figure 1-13 As shown, a safety isolation frame for a cascaded utilization power lithium battery energy storage power station includes:

[0044] A fixed isolation chamber 1, in which a lithium battery 2 is movable;

[0045] The pushing and fixing mechanism 3 includes a base plate 32 and several pushing plates 33 that are movably installed in the fixed isolation chamber 1;

[0046] The lithium battery 2 is driven to move onto the base plate 32 and push against it, so that the push plate 33 is driven to adhere to the lithium battery 2 and lock it in place.

[0047] Specifically, a lithium battery 2 is movably installed inside the fixed isolation chamber 1. The pushing and fixing mechanism 3 includes a bottom support plate 32 and several pushing plates 33 movably installed inside the fixed isolation chamber 1. The bottom support plate 32 can move vertically. The top of the fixed isolation chamber 1 is an open opening for placing the lithium battery 2, and the size of the open opening is larger than the lithium battery 2 to facilitate placement. It also includes a frame 13, on which the fixed isolation chambers 1 are arranged in a linear array. In use, the lithium battery 2 is first held in hand and placed into the open opening. At this time, because... Since the size of the open opening is larger than that of the lithium battery 2, the lithium battery 2 can be easily placed down along the open opening without aligning the edges of the lithium battery 2 with the edges of the fixed isolation chamber 1. When placed down, the lithium battery 2 will first contact the bottom support plate 32, and as the weight of the lithium battery 2 is placed down, it will press down on the bottom support plate 32 to move, thereby driving several push plates 33 to approach the lithium battery 2 together. The push plates 33 will first push the lithium battery 2 towards the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the push plates 33 will also fit against the lithium battery 2 to complete the locking.

[0048] Furthermore, when the base plate 32 moves, the structure that drives several push plates 33 to move together can be a ring rope. The ring rope includes multiple rope loops and two loop ropes slidably connected to the rope loops. The multiple rope loops are respectively fixed to several push plates 33. A fixing rope is provided on the loop rope. The fixing rope is fixed to the base plate 32. When the base plate 32 moves, the fixing rope is pulled and the loop rope is tightened so that several push plates 33 move closer to the lithium battery 2. Alternatively, it can be multiple thumb cylinders fixed to the inner wall of the fixed isolation chamber 1. The output end of the thumb cylinder is fixedly connected to the push plate 33, and the base plate 32 is provided with conductive contacts. When the base plate 32 moves, the conductive contacts are moved to a designated position to trigger multiple thumb cylinders. Then, the output end of the thumb cylinder pushes to push the lithium battery 2 to the designated position and clamp it. Alternatively, any structure known to those skilled in the art can be used.

[0049] In the above technical solution, during installation, the lithium battery 2 is placed in the fixed isolation chamber 1. The space inside the fixed isolation chamber 1 is larger than the size of the lithium battery 2, so the lithium battery 2 can be easily placed in without aligning it with the fixed isolation chamber 1. After the lithium battery 2 is placed on the base plate 32, the weight of the lithium battery 2 itself presses the base plate 32 to slide it, thereby driving several push plates 33 to approach the lithium battery 2 and finally fit together to play a fixing role. At the same time, it will also push the lithium battery 2 to the center of the fixed isolation chamber 1 to facilitate subsequent docking and other processes of the lithium battery 2, and no additional fasteners are required for fixation.

[0050] As a further embodiment of the present invention, the pushing and fixing mechanism 3 also includes a movable main flipping rod 31, and the bottom support plate 32 is driven to move so as to drive the main flipping rod 31 to flip and push a plurality of pushing plates 33 to adhere to the lithium battery 2.

[0051] Specifically, the pushing and fixing mechanism 3 also includes a movable main flipping rod 31. The fixed isolation chamber 1 includes an outer wall sleeve 10, with an upper cover 11 and a bottom plate 12 fixedly connected to both ends of the outer wall sleeve 10, forming a placement space. The upper cover 11 has a placement hole 111, the size of which is larger than the size of the lithium battery 2. Several fixing brackets 121 are provided on the bottom plate 12. The main flipping rod 31 is rotatably connected to the fixing brackets 121. The first end of the main flipping rod 31 (with...) Figure 6 For reference, the first end is the lower end and the second end is the upper end. A drag part 312 is provided, and the second end of the main flipping rod 31 is provided on the push plate 33. When in use, first hold the lithium battery 2 and put it into the placement hole 111. Since the size of the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily put down along the placement hole 111. When it is put in, the lithium battery 2 will first contact the bottom plate 32, and the weight of the lithium battery 2 will press down the bottom plate 32 and move it. At this time, the bottom plate 32 will move to fit the drag part 312. As it continues to press down, the drag part 312 is pressed down and moves in an arc shape, so that the main flipping rod 31 flips along the fixing frame 121, so that several push plates 33 approach the lithium battery 2 together. The push plates 33 will first push the lithium battery 2 towards the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the push plates 33 will also fit the lithium battery 2 and lock it.

[0052] As a further embodiment of the present invention, a detection mechanism 4 is also included, the detection mechanism 4 comprising:

[0053] The auxiliary rotating rod is rotatably connected to the main rotating rod 31;

[0054] Counterweight lock block 441, which is used to lock the bottom support plate 32;

[0055] The push plate 33 is driven away from the lithium battery 2, so as to drive the auxiliary rotating rod to flip and drive the counterweight lock block 441 to unlock the bottom support plate 32.

[0056] Specifically, the detection mechanism 4 includes a secondary rotating rod and a counterweight locking block 441. The secondary rotating rod is rotatably connected to the main flipping rod 31 and is movably mounted on the push plate 33. A limit plate is provided on the main flipping rod 31. Under normal circumstances, the secondary rotating rod is pulled and flipped to fit against the limit plate. The counterweight locking block 441 slides obliquely into the locking hole on the bottom support plate 32 to lock the bottom support plate 32. The normal operating temperature of the conventional lithium battery 2 is -20°C to 60°C. Once it exceeds 60°C, it enters the self-heating stage, which poses a risk of spontaneous combustion and explosion. A detection plate is provided on the push plate 33. When using it, first hold the lithium battery 2 and put it into the placement hole 111. At this time, because the size of the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily put down along the placement hole 111. When putting it in, the lithium battery 2 will first contact the bottom support plate 32, and the weight of the lithium battery 2 will press down and move the bottom support plate 32. When the bottom support plate 32 moves to fit against the dragging part 312, and as it continues to press down, the dragging part 312 is pressed down in an arc shape, so that the main flipping rod 31 flips along the fixed frame 121, so that several push plates 33 approach the lithium battery 2 together. The push plates 33 will first push the lithium battery 2 towards the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the push plates 33 will also fit against the lithium battery 2 to complete the locking. At this time, the counterweight lock block 441 will slide into the locking hole to lock the bottom support plate 32 and connect the lithium battery 2 to the circuit of the energy storage station. When the operating temperature of a part of the lithium battery 2 exceeds 60°, the detection plate detects that the lithium battery 2 has entered the self-heating stage. At this time, the push plates 33 are driven away from the lithium battery 2, so that the auxiliary rotating rod is pushed and pulled away from the limit plate by the push plates 33, and drives the counterweight lock block 441 to slide out of the locking hole, so that the bottom support plate 32 is unlocked and the power to the lithium battery 2 and the energy storage station circuit is cut off.

[0057] In the above embodiments, the structure in which the secondary rotating rod flips to drive the counterweight locking block 441 to slide can be a conductive plate and a thumb cylinder set on the main rotating rod 31. The output end of the thumb cylinder is fixedly connected to the counterweight locking block 441. When the secondary rotating rod flips to the conductive plate, the thumb cylinder is triggered to drive the counterweight locking block 441 to slide out of the locking hole. Alternatively, it can be a three-bar linkage with three ball joints, wherein the two ends of the three-bar linkage are respectively ball jointed to the secondary rotating rod and the counterweight locking block 441, and the middle rod of the three-bar linkage slides on the sliding sleeve. When the secondary rotating rod flips, it pulls the middle rod of the three-bar linkage to slide along the sliding sleeve to pull the counterweight locking block 441 to unlock. Or any structure known to those skilled in the art can be used.

[0058] As the preferred embodiment of the present invention, a memory plastic 41 is provided on the push plate 33, and the memory plastic 41 deforms when heated to drive the push plate 33 away from the lithium battery 2.

[0059] Specifically, the push plate 33 has a linear array of storage slots 333, each of which is fitted with memory plastic 41. The memory plastic 41 is attached to the lithium battery 2, and its temperature change is easily adjustable, allowing precise control of the temperature change at 60°C. In use, the lithium battery 2 is held and placed into the placement hole 111. Because the placement hole 111 is larger than the lithium battery 2, it is easy to place the lithium battery 2 along the hole. Upon placement, the lithium battery 2 first contacts the base plate 32, and the weight of the battery 2 presses down on the base plate 32, causing it to move. The base plate 32 then moves to contact the dragging part 312. As the pressure continues, the dragging part 312 is pressed down in an arc shape, causing the main flipping rod 31 to flip along the fixing frame 121, so that the push plates 33 together... When the lithium battery 2 is near, the push plate 33 will first push the lithium battery 2 toward the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the push plates 33 will also be in contact with the lithium battery 2 to complete the locking. At this time, the counterweight lock block 441 will slide into the locking hole to lock the bottom support plate 32 and connect the lithium battery 2 to the circuit of the energy storage station. When the operating temperature of a part of the lithium battery 2 exceeds 60°, the temperature change temperature of the memory plastic 41 is reached, which means that the lithium battery 2 has entered the self-heating stage. Then the memory plastic 41 deforms and extends the storage groove 333 to push the push plate 33 away from the lithium battery 2, so that the auxiliary rotating rod is pushed and pulled away from the limit plate by the push plate 33, and drives the counterweight lock block 441 to slide out of the locking hole, so that the bottom support plate 32 is unlocked and the power to the lithium battery 2 and the energy storage station circuit is cut off.

[0060] As another embodiment of the present invention, the auxiliary rotating rod is provided with a pulling rope 44 for pulling the counterweight lock block 441 to unlock the bottom support plate 32.

[0061] Specifically, a pull rope 44 is fixedly connected between the auxiliary rotating rod and the counterweight locking block 441. The pull rope 44 is slidably connected to the main rotating rod 31. A guide post and a push sleeve 34 are provided on the base plate 12. The guide post is used to prevent multiple pull ropes 44 from getting tangled together. A sliding post 321 is provided on the base plate 32. The sliding post 321 is slidably connected to the push sleeve 34. A guide hole 342 is opened on the push sleeve 34. The guide hole 342 is in an inclined state. A locking hole is opened on the sliding post 321. The counterweight locking block 441 is slidably connected to the guide hole 342. In use... First, hold the lithium battery 2 and insert it into the placement hole 111. Since the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily placed down along the placement hole 111. When inserting, the lithium battery 2 will first contact the bottom plate 32, and as the weight of the lithium battery 2 is placed, it will press down on the bottom plate 32 and move it. At this time, the bottom plate 32 will move to fit against the drag part 312, and as it continues to press down, the drag part 312 is pressed down in an arc shape, so that the main flipping rod 31 flips along the fixing frame 121. At this time, the counterweight locking block 441 is affected by gravity and tilts. The guide hole 342 slides within the guide hole, pulling the auxiliary rotating rod to flip and fit against the limiting plate, so that several pushing plates 33 move closer to the lithium battery 2 together. The pushing plates 33 will first push the lithium battery 2 towards the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the pushing plates 33 will also fit against the lithium battery 2 to complete the locking. At this time, the guide hole 342 and the locking hole coincide, and the counterweight locking block 441 will slide into the locking hole under the influence of gravity, so as to lock the bottom support plate 32 and connect the lithium battery 2 to the circuit of the energy storage station. When the operating temperature of a part of the lithium battery 2 exceeds 60°, At this point, the temperature change of the memory plastic 41 is reached, which means that the lithium battery 2 has entered the self-heating stage. Then the memory plastic 41 deforms and extends into the storage groove 333 to push the push plate 33 away from the lithium battery 2. This causes the auxiliary rotating rod to be pushed and pulled away from the limiting plate by the push plate 33. As the auxiliary rotating rod rotates, the pulling rope 44 slides along the main rotating rod 31 and pulls the counterweight locking block 441 to slide along the guide hole 342. As the rotating rod rotates, the counterweight locking block 441 finally slides out of the locking hole, so that the bottom support plate 32 is unlocked and the power to the lithium battery 2 and the power storage station is cut off.

[0062] As a further embodiment of the present invention, the base plate 32 is driven to spring up to drive a plurality of push plates 33 away from the lithium battery 2.

[0063] Specifically, a spring 341 is fixedly connected between the sliding column 321 and the base plate 12. The spring 341 is used to push the base plate 32 away from the base plate 12. In use, first hold the lithium battery 2 and insert it into the placement hole 111. Because the size of the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily placed down along the placement hole 111. When inserting, the lithium battery 2 will first contact the base plate 32. After inserting the lithium battery 2, continue to press the lithium battery 2 down by hand to break free from the pushing force of the spring 341 and make the base plate 32 move away from the base plate 12. As plate 32 moves, the bottom support plate 32 moves to fit against the dragging part 312. With continuous downward pressure, the dragging part 312 is pressed down in an arc motion, causing the main flipping rod 31 to flip along the fixed frame 121. At this time, the counterweight locking block 441 is affected by gravity and slides in the inclined guide hole 342 to pull the auxiliary rotating rod to flip and fit against the limiting plate, so that several pushing plates 33 approach the lithium battery 2 together. The pushing plates 33 will first push the lithium battery 2 towards the center of the fixed isolation compartment 1. When the lithium battery 2 reaches the center position, all the pushing plates 33 will also fit against the lithium battery 2. When battery 2 is locked, the guide hole 342 and the locking hole coincide, and the counterweight locking block 441 will slide into the locking hole under the influence of gravity, thereby locking the bottom support plate 32 and connecting the lithium battery 2 to the circuit of the energy storage station. When the operating temperature of a part of the lithium battery 2 exceeds 60°, the temperature change temperature of the memory plastic 41 is reached, which means that the lithium battery 2 has entered the self-heating stage. Then the memory plastic 41 deforms and extends into the storage groove 333, which pushes the push plate 33 away from the lithium battery 2, so that the auxiliary rotating rod is pushed by the push plate 33. Pulling and flipping away from the limiting plate, as the auxiliary rotating rod flips, the pulling rope 44 slides along the main flipping rod 31 and pulls the counterweight locking block 441 to slide along the guide hole 342. As the counterweight locking block 441 flips, it finally slides out of the locking hole, so that the bottom support plate 32 is unlocked. At this time, the spring 341 will push and the bottom support plate 32 away from the bottom plate 12. As the bottom support plate 32 slides, multiple main flipping rods 31 will also flip, so that several pushing plates 33 will simultaneously move away from the lithium battery 2 and lose their clamping ability. At the same time, the power supply to the lithium battery 2 and the energy storage station will be cut off to ensure safety.

[0064] As the preferred embodiment of the present invention, the auxiliary rotating rod includes a rotating auxiliary sleeve 43 rotatably connected to the main rotating rod 31 and a sliding auxiliary rod 42 slidably connected to the rotating auxiliary sleeve 43. The sliding auxiliary rod 42 has a bent portion 421, the rotating auxiliary sleeve 43 has a through hole 431, the pulling rope 44 is fixedly connected to the bent portion 421, and the pulling rope 44 is slidably connected to the through hole 431. The push plate 33 moves in the horizontal direction.

[0065] Specifically, the auxiliary rotating rod includes a rotating sleeve 43 rotatably connected to the main rotating rod 31 and a sliding rod 42 slidably connected to the rotating sleeve 43. The sliding rod 42 has a bent portion 421, the rotating sleeve 43 has a through hole 431, the pulling rope 44 is fixedly connected to the bent portion 421, and the pulling rope 44 is slidably connected to the through hole 431. The push plate 33 is provided with a sliding sleeve 331 along the diagonal, and the outer wall sleeve 10 is provided with a sliding column 101. The sliding column 101 is slidably connected to the sliding sleeve 331 to restrict the push plate 33 to slide only along the central axis direction of the sliding column 101 (i.e., horizontal sliding). The push plate 33 has a vertical sliding groove, and the sliding rod 42 is slidably connected to the vertical sliding groove.In use, first hold the lithium battery 2 and insert it into the placement hole 111. Because the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily placed down along the placement hole 111. When inserting, the lithium battery 2 will first contact the bottom plate 32. After inserting the lithium battery 2, continue to press the lithium battery 2 down by hand to break free from the pushing force of the spring 341 and move the bottom plate 32. At this time, the bottom plate 32 will move to fit against the drag part 312. With continued pressing, the drag part 312 is pressed down and moves in an arc shape, so that the main flipping rod 31 flips along the fixing frame 121. At this time, the counterweight... Under the influence of gravity, the locking block 441 slides within the inclined guide hole 342, pulling the auxiliary rotating rod to flip and fit against the limiting plate. This causes several pushing plates 33 to approach the lithium battery 2 together. The pushing plates 33 first push the lithium battery 2 towards the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the pushing plates 33 also fit against the lithium battery 2 to complete the locking. At this time, the guide hole 342 and the locking hole coincide, and the counterweight locking block 441 slides into the locking hole under the influence of gravity, locking the bottom support plate 32 and connecting the lithium battery 2 to the circuit of the energy storage station. When the operating temperature of a part of the lithium battery 2 exceeds... At 60°C, the temperature change temperature of the memory plastic 41 is reached, indicating that the lithium battery 2 has entered the self-heating stage. The memory plastic 41 then deforms, extending into the receiving groove 333, pushing the push plate 33 away from the lithium battery 2. At this time, the push plate 33 slides along the sliding column 101, causing the sliding auxiliary rod 42 to slide along the vertical groove. Simultaneously, as the rotating auxiliary sleeve 43 rotates, it slides along the inner wall of the rotating auxiliary sleeve 43 to pull the pull rope 44. Because the pull rope 44 is fixed inside the bend 421, it is pulled whenever the sliding auxiliary rod 42 slides or rotates. As the rotating sleeve 43 flips, it is pulled, increasing the pulling distance of the pulling rope 44 without changing the flip angle. Then, the pulling rope 44 pulls the counterweight locking block 441 to slide along the guide hole 342. As it flips, the counterweight locking block 441 finally slides out of the locking hole, unlocking the bottom support plate 32. At this time, the spring 341 pushes the bottom support plate 32 away from the bottom plate 12. As the bottom support plate 32 slides, multiple main flipping rods 31 also flip, causing several pushing plates 33 to simultaneously move away from the lithium battery 2, losing their clamping ability. Simultaneously, the power to the lithium battery 2 and the energy storage station is cut off to ensure safety.

[0066] As a further embodiment of the present invention, a ventilation assembly 5 is also included, which comprises:

[0067] The air guide channel 53 is opened on the push plate 33 and is fixedly connected to the outside.

[0068] Memory plastic 41 blocks the air passage 53.

[0069] Specifically, the air duct 53 is formed on the push plate 33 and is fixedly connected to the outside for ventilation. The memory plastic 41 seals the air duct 53 in its undeformed state. In use, first hold the lithium battery 2 and insert it into the placement hole 111. Because the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily placed down along the placement hole 111. When inserted, the lithium battery 2 will first contact the base plate 32. After inserting the lithium battery 2, continue to press down on the lithium battery 2 to break free from the pushing force of the spring 341 and move the base plate 32. At this time, the base plate 32 will move to fit against the dragging part 312, and with continued downward pressure, the dragging part 312... The main rotating rod 31 is pressed down and moves in an arc shape, causing it to rotate along the fixed frame 121. At this time, the counterweight locking block 441 is affected by gravity and slides in the inclined guide hole 342, pulling the auxiliary rotating rod to rotate and fit against the limiting plate, so that several pushing plates 33 move closer to the lithium battery 2 together. The pushing plates 33 will first push the lithium battery 2 towards the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the pushing plates 33 will also fit against the lithium battery 2 to complete the locking. At this time, the guide hole 342 and the locking hole coincide, and the counterweight locking block 441 will slide into the locking hole under the influence of gravity, so as to lock the bottom support plate 32 and connect the lithium battery 2 to the circuit of the energy storage station. When part of the lithium battery 2 is in the middle of the circuit, the counterweight locking block 441 will slide into the locking hole under the influence of gravity, so as to lock the bottom support plate 32 and connect the lithium battery 2 to the circuit of the energy storage station. When the operating temperature exceeds 60°C, the temperature change temperature of the memory plastic 41 is reached, indicating that the lithium battery 2 has entered the self-heating stage. The memory plastic 41 then deforms, extending into the storage groove 333, pushing the push plate 33 away from the lithium battery 2. At this time, the push plate 33 slides along the sliding column 101, causing the sliding auxiliary rod 42 to slide along the vertical groove. Simultaneously, as the rotating auxiliary sleeve 43 rotates, it slides along the inner wall of the rotating auxiliary sleeve 43 to pull the pull rope 44. Because the pull rope 44 is fixed inside the bend 421, it is pulled when the sliding auxiliary rod 42 slides or rotates, and is also pulled when the rotating auxiliary sleeve 43 rotates. Without changing the flipping angle, the pulling distance of the pull rope 44 is increased, and then the pull rope 44 pulls the counterweight lock block 441 to slide along the guide hole 342. As the counterweight lock block 441 flips, it eventually slides out of the locking hole, so that the bottom plate 32 is unlocked. At this time, the spring 341 will push and the bottom plate 32 away from the bottom plate 12. As the bottom plate 32 slides, multiple main flipping rods 31 will also flip, so that several pushing plates 33 will simultaneously move away from the lithium battery 2 and lose their clamping ability. At the same time, the power supply to the lithium battery 2 and the power storage station will be cut off to ensure safety. After the memory plastic 41 is deformed, it loses its ability to block the air passage 53, so that the air passage 53 can be connected to the outside for auxiliary heat dissipation.

[0070] As the preferred embodiment provided by the present invention, the ventilation assembly 5 further includes a ventilation tube 51, which is used to fixally connect to the air extraction unit, and the air guide channel 53 is movably connected to the ventilation tube 51.

[0071] Specifically, the ventilation pipe 51 is fixedly connected to the base plate 32, and the base plate 12 is provided with a main ventilation pipe 52. Several ventilation pipes 51 are movably connected to the main ventilation pipe 52. The main ventilation pipe 52 is fixedly connected to the exhaust unit (which can be an exhaust fan). The ventilation pipe 51 is provided with an elongated air hole, which can always be connected to the air guide channel 53 when the push plate 33 moves.In use, first hold the lithium battery 2 and insert it into the placement hole 111. Since the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily placed down along the placement hole 111. When inserting, the lithium battery 2 will first contact the bottom plate 32. After inserting the lithium battery 2, continue to press the lithium battery 2 down by hand to break free from the pushing force of the spring 341 and move the bottom plate 32. At this time, the bottom plate 32 will move to fit against the dragging part 312. With continued pressing, the dragging part 312 is pressed down in an arc shape, so that the main flipping rod 31 flips along the fixing frame 121. At this time, the counterweight locking block 441 slides in the inclined guide hole 342 under the influence of gravity. The pull rod flips and fits the limiting plate, causing several push plates 33 to approach the lithium battery 2 together. The push plates 33 first push the lithium battery 2 towards the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the push plates 33 also fit the lithium battery 2 and lock it. At this time, the guide hole 342 and the locking hole coincide, and the counterweight locking block 441 will slide into the locking hole under the influence of gravity, so as to lock the bottom support plate 32 and connect the lithium battery 2 to the circuit of the energy storage station. When the operating temperature of a part of the lithium battery 2 exceeds 60°, the temperature change temperature of the memory plastic 41 is reached, which means that the lithium battery 2 has entered the self-heating stage. Then the memory plastic 41 deforms. The shape deforms and extends into a storage groove 333 to push the push plate 33 away from the lithium battery 2. At this time, the push plate 33 slides along the sliding column 101, so that the sliding auxiliary rod 42 slides along the vertical sliding groove. At the same time, as the rotating auxiliary sleeve 43 flips, it slides along the inner wall of the rotating auxiliary sleeve 43 to pull the pull rope 44. Since the pull rope 44 is fixed in the bend 421, the pull rope 44 will be pulled when the sliding auxiliary rod 42 slides or flips, and will also be pulled as the rotating auxiliary sleeve 43 flips. This increases the distance the pull rope 44 is pulled without changing the flip angle. Then the pull rope 44 pulls the counterweight lock block 441 to slide along the guide hole 342. As it flips... The counterweight locking block 441 eventually slides out of the locking hole, unlocking the bottom support plate 32. At this time, the spring 341 pushes the bottom support plate 32 away from the bottom plate 12. As the bottom support plate 32 slides, multiple main flipping rods 31 also flip, causing several pushing plates 33 to simultaneously move away from the lithium battery 2 and lose their clamping ability. At the same time, the power to the lithium battery 2 and the energy storage station is cut off to ensure safety. After the memory plastic 41 deforms, it loses its ability to block the air passage 53, allowing the air passage 53 to connect to the outside for auxiliary heat dissipation. Then, the exhaust unit can be opened to absorb the heat in the fixed isolation chamber 1 to help cool the lithium battery 2, and to remove the gas that may be emitted when the lithium battery 2 overheats, preventing an explosion.

[0072] As the preferred embodiment of the present invention, the lithium battery 2 is provided with a power interface 21, the fixed isolation chamber 1 is provided with a power connection slot 102, and the bottom support plate 32 is driven to move so as to make the power interface 21 and the power connection slot 102 connected or disconnected.

[0073] Specifically, the lithium battery 2 is provided with a power interface 21, and the fixed isolation compartment 1 is provided with a power connection slot 102. The power connection slot 102 is a concave trapezoid with a certain guiding ability. When the bottom support plate 32 moves, it can make the power interface 21 and the power connection slot 102 pass through or disconnect.In use, first hold the lithium battery 2 and insert it into the placement hole 111. Since the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily placed down along the placement hole 111. When inserting, the lithium battery 2 will first contact the bottom plate 32. After inserting the lithium battery 2, continue to press the lithium battery 2 down by hand to break free from the pushing force of the spring 341 and move the bottom plate 32. At this time, the bottom plate 32 will move to fit against the drag part 312. With continued pressing, the drag part 312 is pressed down in an arc shape, so that the main flipping rod 31 flips along the fixing frame 121. At this time, the counterweight locking block 441 is affected by gravity and slides in the inclined guide hole 342 to pull the auxiliary rotating rod to flip and fit against the limiting plate, so that several pushing... As the plates 33 approach the lithium battery 2, the pushing plates 33 first push the lithium battery 2 towards the center of the fixed isolation chamber 1. When the lithium battery 2 reaches the center position, all the pushing plates 33 also adhere to the lithium battery 2 and lock it in place. At the same time, as the mobile power interface 21 of the bottom support plate 32 approaches the power inlet slot 102 and connects to it electrically to connect to the power storage station circuit, the guide hole 342 and the locking hole overlap, and the counterweight locking block 441 slides into the locking hole under the influence of gravity to lock the bottom support plate 32 and connect the lithium battery 2 to the power storage station circuit. When the operating temperature of a part of the lithium battery 2 exceeds 60°, the temperature change temperature of the memory plastic 41 is reached, which means that the lithium battery 2 has entered the self-heating stage. Then the memory plastic 41... 1. Deformation occurs, extending into a receiving groove 333, which pushes the push plate 33 away from the lithium battery 2. At this time, the push plate 33 slides along the sliding column 101, allowing the sliding auxiliary rod 42 to slide along the vertical slide groove. Simultaneously, as the rotating auxiliary sleeve 43 flips, it slides along the inner wall of the rotating auxiliary sleeve 43 to pull the pull rope 44. Because the pull rope 44 is fixed inside the bend 421, it is pulled when the sliding auxiliary rod 42 slides or flips, and it is also pulled as the rotating auxiliary sleeve 43 flips. This increases the pulling distance of the pull rope 44 without changing the flip angle. Then, the pull rope 44 pulls the counterweight locking block 441 to slide along the guide hole 342. As it flips, the counterweight locking block 441 finally slides out of the locking hole. To unlock the base plate 32, the spring 341 pushes the base plate 32 away from the base plate 12. As the base plate 32 slides, multiple main flipping rods 31 also flip, causing several pushing plates 33 to simultaneously move away from the lithium battery 2 and lose their clamping ability. Simultaneously, as the base plate 32 springs back, the power interface 21 moves away from the power connector 102 to disconnect the electrical connection, cutting off the power to the lithium battery 2 and the energy storage station to ensure safety. After the memory plastic 41 deforms, it loses its ability to block the air passage 53, allowing the air passage 53 to connect to the outside for auxiliary heat dissipation. Then, the exhaust unit can be opened to absorb the heat from the fixed isolation chamber 1 to help cool the lithium battery 2, and to remove gases that might be emitted due to overheating of the lithium battery 2, preventing an explosion.

[0074] As the preferred embodiment of the present invention, a fixing post 334 is provided on the push plate 33, and the center point of the memory plastic 41 is located at the fixing post 334. When heated, the memory plastic 41 deforms in a bulging shape along the fixing post 334.

[0075] Specifically, a fixing post 334 is provided on the push plate 33, and a snap-fit ​​hole is opened at the center point of the memory plastic 41. The snap-fit ​​hole snaps into the fixing post 334. When the memory plastic 41 is heated, it will deform into a bulge shape along the fixing post 334 (the bulge shape is formed by bending along the diagonal of the memory plastic 41 towards the snap-fit ​​hole), so that the push plate 33 is pushed by the deformed memory plastic 41. In use, first hold the lithium battery 2 and put it into the placement hole 111. At this time, because the size of the placement hole 111 is larger than the lithium battery 2, the lithium battery 2 can be easily put down along the placement hole 111. When putting it in, the lithium battery 2 will first contact the bottom plate 32. After the lithium battery 2 is put in, press the lithium battery 2 down with your hand to break free from the pushing force of the spring 341 and move the bottom plate 32. The base plate 32 moves to engage with the dragging part 312. As it continues to press down, the dragging part 312 is pressed down in an arc shape, causing the main flipping rod 31 to flip along the fixed frame 121. At this time, the counterweight locking block 441 is affected by gravity and slides in the inclined guide hole 342 to pull the auxiliary rotating rod to flip and engage with the limiting plate, so that several pushing plates 33 move closer to the lithium battery 2 together. The pushing plates 33 will first push the lithium battery 2 towards the center of the fixed isolation compartment 1. When the lithium battery 2 reaches the center position, all the pushing plates 33 will also engage with the lithium battery 2 to complete the locking. At the same time, as the mobile power interface 21 of the base plate 32 approaches the power connection slot 102 and is electrically connected to it to connect to the power storage station circuit, the guide hole 342 and the locking hole overlap, and the counterweight locking block 441 is affected by gravity. It will slide into the locking hole to lock the bottom support plate 32 and connect the lithium battery 2 to the circuit of the energy storage station. When the operating temperature of a part of the lithium battery 2 exceeds 60°, the temperature change temperature of the memory plastic 41 is reached, which means that the lithium battery 2 has entered the self-heating stage. Then the memory plastic 41 deforms due to heat. At this time, it will deform into a bulge shape along the fixing post 334 (the bulge shape is bent along the diagonal of the memory plastic 41 and close to the snap-fit ​​hole), and deform and extend into the storage groove 333 to push the push plate 33 away from the lithium battery 2. Similarly, when the lithium battery 2 bulges, the temperature will not change, but the bulge will push the push plate 33 away from the lithium battery 2. At this time, the push plate 33 slides along the sliding post 101, so that the sliding auxiliary rod 42 slides along the vertical sliding groove at the same time as it rotates. The flipping of the auxiliary sleeve 43 slides along the inner wall of the rotating auxiliary sleeve 43 to pull the pull rope 44. Because the pull rope 44 is fixed inside the bend 421, the pull rope 44 is pulled when the sliding auxiliary rod 42 slides or flips, and is also pulled when the rotating auxiliary sleeve 43 flips. This increases the pulling distance of the pull rope 44 without changing the flipping angle. Then, the pull rope 44 pulls the counterweight locking block 441 to slide along the guide hole 342. As it flips, the counterweight locking block 441 finally slides out of the locking hole, so that the bottom support plate 32 is unlocked. At this time, the spring 341 will push and move the bottom support plate 32 away from the bottom plate 12. As the bottom support plate 32 slides, multiple main flipping rods 31 will also flip, so that several pushing plates 33 will simultaneously move away from the lithium battery 2 and lose their clamping ability.Simultaneously, as the base plate 32 springs back, the power interface 21 moves away from the power connector 102 to disconnect the electrical connection, cutting off power to the lithium battery 2 and the energy storage station to ensure safety. After the shape memory plastic 41 deforms, it loses its ability to block the air passage 53, allowing the air passage 53 to connect to the outside for auxiliary heat dissipation. Then, the exhaust unit can be opened to absorb heat from the fixed isolation chamber 1 to help cool the lithium battery 2, and to remove gases that might be emitted due to overheating of the lithium battery 2, preventing an explosion.
