[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0029] Embodiment 1

[0030] Such as Figures 1 to 7As shown in the figure, a battery monitoring device according to an embodiment of the present invention includes a battery body 1. A square plate 11 is fixedly connected to the inner top of the battery. A spiral groove 12 is provided on the side wall of the square plate 11, and the cross-section of the spiral groove 12 is convex. A first column 13 is rotatably connected to the center of the square plate 11 through a first circular groove. A driving plate 14 is fixedly connected to one end of the first column 13. A cross groove 15 is provided on the side wall of the driving plate 14. An I-shaped column 16 is slidably connected in the spiral groove 12, and the I-shaped column 16 is slidably connected in the cross groove 15. A power member is provided on the top of the battery body 1, and the rotation of the driving plate 14 is driven by the power member. A second circular groove and a tooth groove 17 are provided on the side wall of the square plate 11. A sealing ring 18 is rotatably connected in the second circular groove. A second column 19 is fixedly connected to the top side wall of the driving plate 14, and the second column 19 penetrates through the sealing ring 18. A limiting gear 2 is provided on the second column 19, and the limiting gear 2 meshes with the tooth groove 17. A first groove 21 and a second groove 22 are respectively provided on the side wall of the limiting gear 2 and the second column 19. An electromagnetic layer 23 is fixedly connected to the side wall of the first groove 21. An electromagnetic block 24 is fixedly connected to the side wall of the electromagnetic layer 23 through a spring, and the electromagnetic block 24 is slidably connected in the first groove 21 and the second groove 22. An equipment box 25 is provided at the end of the I-shaped block. A micro temperature sensor and a micro density sensor are provided in the equipment box 25. A liquid level sensor 26 is provided on the top side wall of the square plate 11. During operation, when the motor 31 operates, the first column 13 is driven to rotate by means of the belt pulley 3 and the toothed belt 34. The driving plate 14 rotates accordingly. Due to the special connection between the I-shaped column 16 in the spiral groove 12 and the cross groove 15, the rotation of the driving plate 14 drives the I-shaped column 16 to spiral up and down along the spiral groove 12, and the equipment box 25 connected to the end moves synchronously. Thus, the temperature sensor and the density sensor in the equipment box 25 can monitor the electrolyte at different positions and different heights. At the same time, this movement mode fits the characteristic of the small distance between the plates, conforms to the internal working conditions of the existing lead-acid battery, and has a wide application prospect. At the same time, the sealing ring 18 in the second circular groove on the side wall of the square plate 11, in cooperation with the meshing of the second column 19, the limiting gear 2 and the tooth groove 17, maintains the sealing of the internal rotating structure and limits the rotation angle of the driving plate 14. By selecting whether to energize the electromagnetic layer 23, the position of the driving plate 14 can be limited. When the electromagnetic layer 23 is energized, the second column 19 cannot drive the limiting gear 2. At this time, the driving plate 14 rotates around the first column 13. At the same time, the limiting gear 2 moves in the tooth groove 17. When the driving plate 14 moves to a specified position and its rotation is not required, the electromagnetic layer 23 is powered off. At this time, the second column 19 can drive the limiting gear 2 to rotate, but the second column 19 and the driving plate 14 are fixedly connected, so that the limiting gear 2 and the tooth groove 17 are mutually locked, thereby fixing one end of the driving plate 14 and avoiding the problem that when the sensor does not need to be displaced, due to external shaking, the driving plate 14 rotates deviantly, resulting in inaccurate monitoring positions of the sensor.

[0031] The power component includes a pulley 3. A motor 31 is fixedly connected to the top of the battery body 1. A connecting shaft is fixedly connected to the output end of the motor 31. Pulleys 3 are fixedly connected to both the connecting shaft and the first column 13, and the diameter of the pulley 3 on the connecting shaft is smaller than that of the pulley 3 on the first column 13. A toothed belt 34 is used for transmission between a pair of the pulleys 3. A containing groove 35 is formed in the top of the square plate 11 and penetrates upward through the battery body 1, and the toothed belt 34 is located in the containing groove 35. During operation, the motor 31 is started as a power source, and the connecting shaft at its output end rotates. The pulleys 3 on the connecting shaft and the first column 13 rely on the toothed belt 34 for transmission. The containing groove 35 on the top of the square plate 11 provides an installation and operation space for the toothed belt 34 and also protects the toothed belt 34 transmission structure from external interference, thereby driving the driving plate 14 fixedly connected to the first column 13 to rotate, providing a power basis for the equipment box 25 to move in the battery body 1 along a predetermined spiral trajectory to monitor electrolyte parameters at different depths.

[0032] Embodiment 2

[0033] As Figures 1 to 7 shown, a transmission gear 4 is fixedly connected to the connecting shaft. A fixed block 41 and a pair of fixed columns are fixedly connected to the top of the battery body 1. A pump housing 42 is fixedly connected between the pair of fixed columns. A transmission gear 4 is fixedly connected to the connecting shaft. A first shaft is rotatably connected inside the pump housing 42 and penetrates through the pump housing 42 and is rotatably connected to the side wall of the fixed block 41. A speed increasing gear 43 is fixedly connected to the first shaft, and the speed increasing gear 43 meshes with the transmission gear 4. A second shaft is rotatably connected between the relatively inner side walls of the pump housing 42. Drainage gears 44 are fixedly connected to both the first shaft and the second shaft, and a pair of the drainage gears 44 mesh with each other. A liquid drainage member is provided at the top of the battery body 1, and the liquid drainage member is conveyed through the drainage gears 44. During operation, the motor 31 drives the connecting shaft to rotate. The transmission gear 4 on the connecting shaft meshes with the speed increasing gear 43 on the first shaft inside the pump housing 42. Since the number of teeth of the speed increasing gear 43 is smaller than that of the transmission gear 4, speed increase is achieved, so that the rotation speed of the first shaft is higher than that of the connecting shaft. The drainage gears 44 on the first shaft and the second shaft mesh with each other. The rapid rotation of the first shaft drives the second shaft to rotate synchronously in the opposite direction, forming a driving force for liquid flow inside the pump housing 42 to convey the liquid from one end of the pump housing 42 to the other end, providing power for subsequent liquid circulation and heat dissipation. The connection between the connecting shaft and the first shaft, and between the first shaft and the second shaft through the drainage gears 44 constructs a complete power transmission path from the motor 31 to the liquid drive inside the pump housing 42.

[0034] The liquid driving member includes a cooling shell 5, the cooling shell 5 is fixedly connected to the top of the battery body 1, an S-shaped diversion groove is provided in the cooling shell 5, a pair of connecting pipes 52 are fixedly connected to the cooling shell 5 through a pair of communication grooves, a spiral cooling groove 53 is provided at the proximal end of the spiral groove 12 inside the square plate 11, and the pair of connecting pipes 52 are respectively communicated with the center inside the spiral cooling groove 53 and the inside of the top end of the pump housing 42, and a delivery pipe 54 is fixedly connected between the bottom end inside the pump housing 42 and the top end inside the spiral cooling groove 53; during operation, the liquid driving gear 44 in the pump housing 42 operates to transport the liquid from the top end of the pump housing 42 to the spiral cooling groove 53 through the connecting pipe 52. The liquid absorbs the heat of the electrolyte during the flow in the spiral cooling groove 53, and then returns to the bottom end of the pump housing 42 through the delivery pipe 54 and is circulated and transported by the liquid driving gear 44. The S-shaped diversion groove, the connecting pipe 52, the spiral cooling groove 53 and the delivery pipe 54 in the cooling shell 5 together form a closed liquid circulation loop. By running the motor 31, it drives the position change of the sensor and the flow of the coolant in the spiral cooling groove 53 at the same time. During the displacement of the sensor, the heat generated by the operation and friction of the equipment is synchronously cooled by the liquid in the spiral cooling groove 53. The S-shaped diversion groove of the cooling shell 5 increases the liquid residence time and the heat dissipation area, effectively reducing the temperature of the electrolyte, ensuring that the battery works within an appropriate temperature range and extending the service life of the battery.

[0035] A group of diversion grooves 6 are provided on the inner circular wall of the spiral cooling groove 53, and the diversion grooves 6 are arranged in a twisted shape; during operation, the liquid flows in the spiral cooling groove 53, and the twisted diversion grooves 6 on the inner circular wall of the groove change the liquid flow path, making it move along the twisted path; this increases the contact time and area between the liquid and the wall of the spiral cooling groove 53, increases the probability of the coolant mixing and colliding, makes the temperature of the coolant more average, and further enables the liquid to absorb heat more fully, improving the heat dissipation efficiency and ensuring the stable performance of the battery.

[0036] Embodiment III

[0037] As Figures 1 to 7 shown, a pair of T-blocks 7 are slidably connected to the side wall of the square plate 11 through a pair of T-grooves, a connecting rod 71 is fixedly connected between the pair of T-blocks 7, and the connecting rod 71 penetrates through the equipment box 25; during operation, the I-shaped column 16 drives the equipment box 25 to perform a spiral movement, and the T-blocks in the T-grooves on the side wall of the square plate 11 slide accordingly. The connecting rod 71 fixedly connected between the T-blocks and penetrating through the equipment box 25 provides additional support and guidance for the movement of the equipment box 25. This structural design ensures the stable movement of the equipment box 25, avoids affecting the measurement accuracy of the micro temperature sensor and the micro density sensor due to uneven force or shaking, and ensures the accuracy of the monitoring data; at the same time, it can prevent the monitoring directions of the temperature sensor and the density sensor in the equipment box 25 from changing.

[0038] The cooling shell 5 is arranged in an arc shape, and the outer arc surface of the cooling shell 5 is inclined towards the motor 31; during operation, the motor 31 generates heat, and the design of the cooling shell 5 being arc-shaped and the outer arc surface being inclined towards the motor 31 comes into play; the arc-shaped outer surface of the cooling shell 5 changes the flow direction of the surrounding air, making the air flow more smoothly over the surface of the cooling shell 5. On the one hand, it accelerates the diffusion of the heat dissipated by the liquid in the cooling shell 5 to the surrounding environment. On the other hand, it uses the hot air flow generated by the motor 31 to promote the air convection on the surface of the cooling shell 5, enhancing the overall heat dissipation effect and further improving the heat dissipation efficiency of the battery body 1.

[0039] Working principle: When the motor 31 operates, the first column 13 is driven to rotate by means of the belt pulley 3 and the toothed belt 34, and the plate 14 rotates accordingly. Due to the special connection of the I-shaped column 16 in the spiral groove 12 and the cross groove 15, driving the rotation of the plate 14 causes the I-shaped column 16 to spiral up and down along the spiral groove 12, and the equipment box 25 connected to the end moves synchronously. As a result, the temperature sensor and density sensor in the equipment box 25 can monitor the electrolyte at different positions and different heights. At the same time, this movement mode fits the characteristic of the small distance between the plates, conforms to the internal working conditions of the existing lead-acid battery, and has a wide application prospect. At the same time, the sealing ring 18 in the second circular groove on the side wall of the square plate 11, in cooperation with the second column 19 and the meshing of the limiting gear 2 and the tooth groove 17, maintains the sealing of the internal rotating structure and limits the rotation angle of the driving plate 14. By choosing whether to energize the electromagnetic layer 23, the position of the driving plate 14 can be limited. When the electromagnetic layer 23 is energized, the second column 19 cannot drive the limiting gear 2. At this time, the driving plate 14 rotates around the first column 13. At the same time, the limiting gear 2 moves in the tooth groove 17. When the driving plate 14 moves to the designated position and its rotation is not required, the electromagnetic layer 23 is powered off. At this time, the second column 19 can drive the limiting gear 2 to rotate, but the second column 19 and the driving plate 14 are fixedly connected, so that the limiting gear 2 and the tooth groove 17 are engaged with each other, thereby fixing one end of the driving plate 14, avoiding the problem that when the sensor does not need to be displaced, due to external shaking, the driving plate 14 rotates deviantly, resulting in inaccurate sensor monitoring position. The motor 31 is started as a power source, and the connecting shaft at its output end rotates. The connecting shaft and the belt pulley 3 on the first column 13 are driven by the toothed belt 34. The containing groove 35 at the top of the square plate 11 provides an installation and operating space for the toothed belt 34, and also protects the toothed belt 34 transmission structure from external interference, thereby driving the driving plate 14 fixedly connected to the first column 13 to rotate, providing a power basis for the equipment box 25 to move in the battery body 1 along a predetermined spiral trajectory to realize the monitoring of electrolyte parameters at different depths. The motor 31 drives the connecting shaft to rotate, and the transmission gear 4 on the connecting shaft meshes with the speed increasing gear 43 on the first shaft in the pump housing 42. Since the number of teeth of the speed increasing gear 43 is less than that of the transmission gear 4, speed increase is achieved, and the rotation speed of the first shaft is higher than that of the connecting shaft. The liquid driving gears 44 on the first shaft and the second shaft mesh with each other. The rapid rotation of the first shaft drives the second shaft to rotate synchronously in the opposite direction, forming a driving force for liquid flow in the pump housing 42, and conveying the liquid from one end of the pump housing 42 to the other end, providing power for subsequent liquid circulation and heat dissipation;The connection between the connecting shaft and the first shaft, and the first shaft and the second shaft are connected through the liquid driving gear 44, so as to construct a complete power transmission path from the motor 31 to the liquid drive in the pump housing 42. The liquid driving gear 44 in the pump housing 42 rotates to transport the liquid from the top of the pump housing 42 to the spiral cooling groove 53 through the connecting pipe 52. The liquid absorbs the heat of the electrolyte during the flow in the spiral cooling groove 53, and then returns to the bottom of the pump housing 42 through the delivery pipe 54, and is circulated and transported by the liquid driving gear 44. The S-shaped guide groove in the cooling housing 5, the connecting pipe 52, the spiral cooling groove 53 and the delivery pipe 54 together constitute a closed liquid circulation loop. The motor 31 is operated, and at the same time, the position change of the sensor and the flow of the coolant in the spiral cooling groove 53 are driven. During the displacement of the sensor, the heat caused by the operation of the equipment and the friction is synchronously cooled by the liquid in the spiral cooling groove 53. The S-shaped guide groove of the cooling shell 5 increases the liquid residence time and the heat dissipation area, effectively reduces the electrolyte temperature, ensures that the battery works within the appropriate temperature range, and prolongs the battery life. The liquid flows in the spiral cooling groove 53, and the twisted guide groove 6 on the inner circular wall of the groove changes the liquid flow path, so that it moves along the twisted path; this increases the liquid and the spiral cooling groove. The contact time and area of ​​the coolant tank 53 wall increase the probability of coolant mixing and collision, making the coolant temperature more uniform, so that the liquid can absorb heat more fully, improve the heat dissipation efficiency, and ensure the stability of battery performance. The I-shaped column 16 drives the equipment box 25 to make a spiral motion, and the T block in the T groove of the side wall of the square plate 11 slides accordingly. The connecting rod 71 fixedly connected between the T blocks and penetrating the equipment box 25 provides additional support and guidance for the movement of the equipment box 25. This structural design ensures the stable movement of the equipment box 25 and avoids the influence of uneven force or shaking on the measurement accuracy of the micro temperature sensor and the micro density sensor. Ensure the monitoring data is accurate; at the same time, the monitoring direction of the temperature sensor and density sensor in the equipment box 25 can remain unchanged, the motor 31 generates heat, and the design of the arc-shaped cooling shell 5 with the outer arc surface tilted toward the motor 31 plays a role; the arc-shaped outer surface of the cooling shell 5 changes the flow direction of the surrounding air, allowing the air to flow more smoothly over the surface of the cooling shell 5, on the one hand, accelerating the heat dissipated by the liquid in the cooling shell 5 to diffuse to the surrounding environment, and on the other hand, using the hot air flow generated by the motor 31 to promote air convection on the surface of the cooling shell 5, enhancing the overall heat dissipation effect, and further improving the heat dissipation efficiency of the battery body 1. ;
