Description

Technical Field

[0001] This utility model belongs to the technical field of circuit protection devices, specifically a lithium iron phosphate battery with a circuit protection device. Background Technology

[0002] With the development of energy storage technology, large-scale energy storage power stations have become an important means of reliable power supply for power systems. Energy storage power stations provide power output by charging and discharging a large number of individual batteries. Therefore, there are certain risks in the voltage and current of the power station during operation, and current protection devices are needed to protect the power station. Leakage current protectors are a type of circuit protection device.

[0003] Meanwhile, a circuit protection device for lithium iron phosphate battery energy storage, with announcement number CN216290294U, is disclosed. It includes a mounting box and a circuit protector body. A fixing plate is fixedly installed in the middle of the mounting box. A slot is opened on the top of the fixing plate. The circuit protector body is snapped into the slot. Triangular grooves are opened at both ends of both sides inside the mounting box. Trapezoidal clamping blocks are installed inside the triangular grooves. A bidirectional threaded rod is rotatably installed in the middle of the bottom inside the mounting box. Moving strips are threaded to both sides of the bidirectional threaded rod. The top two sides of the two moving strips are respectively connected to four trapezoidal clamping blocks.

[0004] The aforementioned circuit protection device for lithium iron phosphate battery energy storage simply fixes the circuit protector to the battery during use. However, if the battery is subjected to impact without a protection device, it will increase the possibility of spontaneous combustion of the battery and increase the danger of use.

[0005] Therefore, a lithium iron phosphate battery with a circuit protection device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a lithium iron phosphate battery with a circuit protection device, which has the advantages of making the installation of the battery protection device more convenient, being reusable, saving costs, and preventing damage caused by impact.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lithium iron phosphate battery with a circuit protection device, comprising a protection plate, a fixing plate fixedly disposed above the protection plate, a threaded rod fixedly disposed on the rear side of the fixing plate, a nut screwed on the outer side of the threaded rod, a threaded rod screwed on the inner side of the nut, a fixing plate fixedly disposed on the rear side of the threaded rod, a protection plate two fixedly disposed below the fixing plate, a protective cover fixedly disposed above the protection plate two, and the protective cover is fixedly disposed with the protection plate one, a limiting block fixedly disposed on the rear side of the protection plate one, and the limiting block is fitted with the protection plate two, and a limiting groove is formed inside the protection plate two.

[0008] Preferably, a fixing groove is provided inside the lower part of the first protective plate, a fixing rod is slidably provided inside the lower part of the first protective plate, a spring is attached to the outside of the fixing rod, a semicircle is slidably provided inside the first protective plate, a connecting rod is fixedly provided below the semicircle, an inclined ring is slidably provided outside the connecting rod, a connecting block is fixedly provided below the connecting rod, a hydraulic telescopic column is fixedly provided below the connecting block, and a base plate is fixedly provided outside the connecting block.

[0009] By adopting the above technical solution and setting up a hydraulic telescopic column, during connection and installation, the hydraulic telescopic column extends and retracts, causing the semicircle to enter the fixing groove. The arc on the semicircle fits against the inclined surface on the fixing rod, causing the fixing rod to extend outward. When the semicircle moves above the fixing rod, the fixing rod follows the spring's rebound, locking the fixing rod in the gap between the inclined ring and the semicircle for fixation. Simultaneously, during disassembly, the hydraulic telescopic column is raised. Because the inclined ring has the same inclined surface as the fixing rod, the fixing rod is locked below the inclined ring. At this time, the hydraulic telescopic column is lowered, causing the semicircle and the inclined ring to fit together. When the fixing rod moves onto the semicircle through the inclined surface, the device is separated. This design makes it space-saving when not in use and easy to store.

[0010] Preferably, a placement groove is provided above the base plate, a rotating shaft is fixedly provided above the base plate, a bidirectional threaded rod is rotatably provided above the rotating shaft, a turntable is fixedly provided above the bidirectional threaded rod, a second nut is spirally provided on the outside of the bidirectional threaded rod, a first rotating shaft is fixedly provided on the outside of the second nut, a connecting plate is provided for the rotation of the first rotating shaft, a second rotating shaft is rotatably provided at the end of the connecting plate, and a second fixing plate is fixedly provided on the outside of the second rotating shaft.

[0011] By adopting the above technical solution and setting up a placement slot, after the battery is placed in the placement slot, the turntable is rotated, causing the bidirectional threaded rod to rotate together with the rotating shaft, causing the second nut to move outside the bidirectional threaded rod, and causing the connecting plate to rotate with the first and second rotating shafts. The battery is clamped by the second fixing plate, fixing the battery in the placement slot, protecting the battery, preventing damage from impact, and reducing maintenance costs.

[0012] Preferably, an electric slide rail is fixedly provided on the front side of the protective plate, a slider is slidably provided inside the electric slide rail, and a fan is fixedly provided on the front side of the slider.

[0013] By adopting the above technical solution, when the temperature sensor in the circuit protector detects that the battery temperature is too high and cuts off the charging, the slider 1 slides in the electric slide rail 1, causing the fan to move to dissipate heat, so that the battery can be cooled down quickly and its working efficiency is not affected.

[0014] Preferably, a hydraulic telescopic rod is fixedly provided on the rear side of the first protective plate, an electric slide rail is fixedly provided on the rear side of the hydraulic telescopic rod, a slider is slidably provided inside the electric slide rail, and a circuit protector is fixedly provided on the rear side of the slider.

[0015] By adopting the above technical solution, a hydraulic telescopic rod is set up. The vertical position of the circuit protector is adjusted by extending and retracting the hydraulic telescopic rod. The front and rear positions of the circuit protector are adjusted by sliding the second slider in the second electric slide rail. After the adjustment is completed, the circuit protector is installed on the battery for protection, so that the protection device and the battery are integrated into one structure to protect the battery.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, by setting threaded rods, allows for the vertical placement of protection plate one and protection plate two during installation of the protection device. The limiting block enters the limiting groove, aligning the threaded rods on protection plate one and protection plate two. By rotating nut one, the threaded rods on protection plate one and protection plate two are connected together for assembly. Disassembly is simple: just rotate nut one to separate the threaded rods. This design makes the installation of the battery protection device more convenient, allows for reuse, and saves costs.

[0018] 2. This utility model, by setting up a placement slot, allows the battery to be placed in the slot. Rotating the turntable causes the bidirectional threaded rod to rotate along with the rotating shaft, moving the second nut outside the bidirectional threaded rod. This causes the connecting plate to rotate with the first and second rotating shafts, clamping the battery through the second fixing plate. This secures the battery in the placement slot, protecting it from impact damage and reducing maintenance costs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The following describes an embodiment of this utility model based on its overall structure.

[0027] like Figures 1 to 5 As shown, this utility model provides a lithium iron phosphate battery with a circuit protection device, including a protection plate 1, a fixing plate 5 fixedly mounted above the protection plate 1, a threaded rod 6 fixedly mounted on the rear side of the fixing plate 5, a nut 7 spirally mounted on the outer side of the threaded rod 6, a threaded rod 6 spirally mounted inside the nut 7, the fixing plate 5 fixedly mounted on the rear side of the threaded rod 6, a protection plate 2 fixedly mounted below the fixing plate 5, and a protective cover 4 fixedly mounted above the protection plate 2, and the protective cover 4 is fixedly mounted to the protection plate 1. A limiting block 8 is fixedly provided on the rear side of the device, and the limiting block 8 is fitted with the second protective plate 2. The second protective plate 2 has a limiting groove 9 inside and a threaded rod 6 is provided. When installing the protective device, the first protective plate 1 and the second protective plate 2 are placed vertically so that the limiting block 8 enters the limiting groove 9. The threaded rod 6 on the first protective plate 1 and the second protective plate 2 is aligned. By rotating the first nut 7, the threaded rod 6 on the first protective plate 1 and the second protective plate 2 are connected together to assemble them. When disassembling, simply rotate the first nut 7 to separate the threaded rod 6.

[0028] In this embodiment, a fixing groove 26 is provided inside the lower part of the protective plate 1, and a fixing rod 27 is slidably provided inside the lower part of the protective plate 1. A spring 28 is attached to the outside of the fixing rod 27. A semicircle 30 is slidably provided inside the protective plate 1, and a connecting rod 32 is fixedly provided below the semicircle 30. An inclined ring 31 is slidably provided outside the connecting rod 32. A connecting block 33 is fixedly provided below the connecting rod 32, and a hydraulic telescopic column 29 is fixedly provided below the connecting block 33. A base plate 3 is fixedly provided outside the connecting block 33. When the hydraulic telescopic column 29 is installed, it extends and retracts, causing the semicircle 30 to enter the fixing groove 26, so that the arc on the semicircle 30 fits against the inclined surface on the fixing rod 27, causing the fixing rod 27 to extend outward. When the spring 28 moves to the top of the fixed rod 27, the fixed rod 27 follows the rebound of the spring 28, causing the fixed rod 27 to be locked in the gap between the inclined ring 31 and the semicircle 30 for fixation. Simultaneously, during disassembly, the hydraulic telescopic column 29 is raised. Because the inclined ring 31 has the same inclined surface as the fixed rod 27, the fixed rod 27 is locked below the inclined ring 31. Then, the hydraulic telescopic column 29 is lowered, causing the semicircle 30 and the inclined ring 31 to fit together. When the fixed rod 27 is moved onto the semicircle 30 through the inclined surface, the device is separated. This design makes it space-saving when not in use and easy to store. A placement slot 13 is provided above the base plate 3. A rotating shaft 16 is fixed above the base plate 3. A bidirectional threaded rod 15 is rotatably mounted above the rotating shaft 16. A fixed... A turntable 14 is provided. A second nut 17 is spirally attached to the outer side of a bidirectional threaded rod 15. A rotating shaft 18 is fixedly attached to the outer side of the second nut 17. A connecting plate 19 is provided for the rotation of the first rotating shaft 18. A second rotating shaft 20 is rotatably attached to the end of the connecting plate 19. A fixing plate 21 is fixedly attached to the outer side of the second rotating shaft 20. A placement slot 13 is provided. When the battery is placed in the placement slot 13, rotating the turntable 14 causes the bidirectional threaded rod 15 to rotate along with the first rotating shaft 18. This causes the second nut 17 to move outside the bidirectional threaded rod 15, and the connecting plate 19 to rotate along with the first rotating shaft 18 and the second rotating shaft 20. The fixing plate 21 clamps the battery, securing it within the placement slot 13 and protecting it from impact damage, thus reducing maintenance costs. An electric slide rail 10 is fixedly installed on the front side of the circuit protector 25. A slider 11 slides inside the electric slide rail 10. A fan 12 is fixedly installed on the front side of the slider 11. When the temperature sensor in the circuit protector 25 detects that the battery temperature is too high and cuts off charging, the slider 11 slides in the electric slide rail 10, causing the fan 12 to move for heat dissipation, thus quickly cooling the battery and preventing it from affecting working efficiency. A hydraulic telescopic rod 22 is fixedly installed on the rear side of the protection plate 1. An electric slide rail 23 is fixedly installed on the rear side of the hydraulic telescopic rod 22. A slider 24 slides inside the electric slide rail 23. A circuit protector 25 is fixedly installed on the rear side of the slider 24. The hydraulic telescopic rod 22 is used to adjust the vertical position of the circuit protector 25 by extending and retracting it.The position of the circuit protector 25 is adjusted by sliding the slider 24 within the electric slide rail 23. After adjustment, the circuit protector 25 is installed onto the battery for protection, making the protection device and battery an integrated structure to protect the battery.

[0029] The working principle and process of a lithium iron phosphate battery with circuit protection device:

[0030] When using a lithium iron phosphate battery with a circuit protection device, the protection plate 1 and protection plate 2 are installed vertically, with the limiting block 8 entering the limiting groove 9. The threaded rods 6 on protection plate 1 and protection plate 2 are aligned, and the threaded rods 6 on protection plate 1 and protection plate 2 are connected by rotating nut 7. Simultaneously, during the connection and installation, the hydraulic telescopic column 29 extends and retracts, causing the semicircle 30 to enter the fixing groove 26, so that the arc of the semicircle 30 fits against the fixing rod 27. The inclined plane causes the fixing rod 27 to extend outward. When the semicircle 30 moves above the fixing rod 27, the fixing rod 27 follows the rebound of the spring 28, causing the fixing rod 27 to be fixed in the gap between the inclined ring 31 and the semicircle 30, connecting the protection plate 1 and the base plate 3. After the battery is placed in the placement slot 13, the turntable 14 is rotated, causing the bidirectional threaded rod 15 to rotate with the rotating shaft 18, causing the nut 17 to move outside the bidirectional threaded rod 15, and causing the connecting plate 19 to rotate with the rotating shaft 18 and the rotating shaft 20. The fixing plate 21 clamps the battery, securing it within the placement slot 13 and protecting it. The vertical position of the circuit protector 25 is adjusted by the extension and retraction of the hydraulic telescopic rod 22. The forward and backward position of the circuit protector 25 is adjusted by the sliding block 24 within the electric slide rail 23. After adjustment, the circuit protector 25 is installed onto the battery for protection, making the protection device and battery an integrated structure. When the temperature sensor in the circuit protector 25 detects that the battery temperature is too high, it cuts off the charging process. When powered, slider 11 slides in electric slide rail 10, causing fan 12 to move for heat dissipation, thus quickly cooling the battery and ensuring it does not affect working efficiency. When disassembling, turn nut 7 to separate threaded rod 6, raising hydraulic telescopic column 29. Because inclined ring 31 has the same inclined surface as fixed rod 27, fixed rod 27 is stuck below inclined ring 31. At this time, the hydraulic telescopic column 29 is lowered, causing semicircle 30 to fit with inclined ring 31. When fixed rod 27 moves onto semicircle 30 through the inclined surface, the device is separated.
