Description

Technical Field

[0001] The present invention relates to the technical field of battery safety monitoring, and more specifically, to a safety monitoring device for batteries in energy storage power stations. Background Art

[0002] In modern energy storage power stations, the heat dissipation management and safety monitoring of battery packs face severe technical challenges. Although the widely used water-cooled heat dissipation system is the mainstream heat dissipation solution, it has limitations in actual operation. The heat generation characteristics of the battery under different working conditions show significant non-uniformity, especially when operating at high loads. Some battery cells may generate severe heat. This uneven temperature distribution not only increases the burden on the heat dissipation system, but also brings great difficulties to real-time temperature monitoring.

[0003] The existing water cooling system mainly relies on a circulation pump to achieve the flow of coolant and heat exchange. This single heat dissipation method is difficult to respond quickly to temperature changes. When the battery load changes suddenly, the system cannot adjust the cooling intensity in time, causing the temperature monitoring data to lag behind the actual situation. This monitoring lag makes it impossible for the system to accurately grasp the real-time working status of the battery pack and cannot detect potential safety hazards in time. Summary of the invention

[0004] 1. Technical issues to be resolved

This structural design connects the double-side blocks through the transverse rod, thereby ensuring the synchronous movement of the double-side blocks; the design of the planar groove limits the movement trajectory of the double-side blocks to prevent deviation; the coaxially designed insertion ring ensures the concentricity between the rotating sleeve and the control tube, thereby improving the stability and sealing of the overall structure.

[0009] Preferably, a threaded rod is installed in the internal thread of the rotating sleeve, the threaded rod is pressed against the fitting plate, a spring is installed on the fitting plate, and the other end of the spring is pressed against the double-side blocks. The design of the spring also provides the necessary preload force for the system, ensuring the stability of the adjustment mechanism under various working conditions.

[0010] Preferably, the plurality of memory springs are made of memory metal material. The selection of memory metal material enables the memory spring to respond sensitively to temperature changes and automatically deform when the temperature rises, thereby realizing an automatic adjustment function without the need for external energy drive, thereby improving the reliability and response speed of the system.

[0011] Preferably, the connecting mechanism also includes an outlet pipe installed on the water outlet trough and a water inlet pipe installed on the water inlet trough, and the water inlet pipe and the water outlet pipe are respectively fixedly installed with an external sleeve. The design of this water inlet and outlet system ensures the smooth circulation of cooling water through a special pipeline and sleeve structure; the design of the external sleeve provides a reliable interface for pipeline connection, which facilitates the installation and maintenance of the system.

[0012] Preferably, each of the external sleeves is slidably connected to an external pipe, the external pipe is connected to an external water supply device, two sealing rings are installed on the external pipe, two embedding grooves are provided on the external sleeve, the sealing rings are inserted into the embedding grooves, a vertical groove is provided on the external sleeve, and the external folding plate is slidably connected in the vertical groove.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a safety monitoring device for batteries in energy storage power stations, which has the following beneficial effects:

[0019] The device adopts a double-layer water channel design, including external circulation and internal circulation channels. When the battery temperature is normal, the cooling water circulates quickly mainly through the external channel; when the temperature rises, the water flow path will be automatically adjusted under the action of the memory spring, so that the cooling water enters the internal channel for heat exchange over a larger area. This adaptive water channel switching mechanism ensures the dynamic matching of heat dissipation efficiency and heat generation. The system innovatively uses spring elements made of memory metal materials, which can respond quickly to temperature changes. When the cooling water temperature rises, the memory metal spring will deform and change the cross-sectional area of ​​the water flow channel by pushing the adjustment block, thereby automatically adjusting the flow direction of the cooling water. This adaptive adjustment does not require external energy drive. Mechanism improves the reliability and response speed of the system. The device adopts a multiple sealing design, including threaded sealing, elastic ring sealing and other multi-layer protection. Especially at the water pipe connection, an innovative folding plate locking mechanism is adopted. The stability and sealing of the connection are ensured through the cooperation of spring force and thread thrust. This design not only prevents the leakage of coolant, but also facilitates the rapid installation and disassembly of pipelines. The system has multiple safety protection mechanisms. When the temperature rises abnormally, the memory metal sensing system will immediately trigger the water channel adjustment to increase the cooling intensity. At the same time, the special water channel design ensures that even if some channels are blocked, the system can still maintain basic heat dissipation function, effectively preventing the risk of battery overheating.

[0020] This safety monitoring device significantly improves the safety performance of the energy storage power station through innovative designs such as temperature adaptive adjustment and intelligent water channel control. Its ability to achieve automatic adjustment without the need for an external control system improves overall reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figures 1 to 9 A safety monitoring device for a battery in an energy storage power station comprises a battery body 11 and a water-cooling plate 12 attached to the battery body 11; and also comprises an adjusting mechanism, the adjusting mechanism comprising a plurality of external grooves 21 provided on the water-cooling plate 12 and internal grooves 22 provided in the external grooves 21, each of the external grooves 21 is provided with an internal hole 23, and each of the water-cooling plates 12 is respectively provided with a control tube 24 connected to the internal hole 23, the control tube 24 is slidably connected in a rotating sleeve 25, a sealing sleeve 26 is threadedly connected to the control tube 24, and the sealing sleeve 26 is pressed on the control tube 24, and a vertical hole 27 and a semicircular groove 28 are respectively provided on the outer wall of the rotating sleeve 25, and two sealing sleeves 26 are slidably connected in the rotating sleeve 25. The rotary sleeve 25 has two side blocks 29, on which a plurality of memory springs 210 are mounted, and the plurality of memory springs 210 are pressed against the inner wall of the rotary sleeve 25. The adjustment mechanism also includes a transverse rod 211 mounted on the two side blocks 29. The rotary sleeve 25 is provided with a plane groove 212. The two side blocks 29 are respectively slidably connected in the plane groove 212, and an insertion ring 213 is coaxially mounted on the rotary sleeve 25. The insertion ring 213 is inserted into the control tube 24. A threaded rod 214 is mounted on the inner thread of the rotary sleeve 25. The threaded rod 214 is pressed against the bonding plate 215. A spring 216 is mounted on the bonding plate 215. The other end of the spring 216 is pressed against the two side blocks 29. The plurality of memory springs 210 are made of memory metal.

[0035] When cooling the battery body 11, since the water cooling plate 12 is attached to the battery body 11, water is first introduced into the water inlet groove 32 through the water supply equipment, and multiple external grooves 21 are connected to the water inlet groove 32, so the cooling water will be introduced into the corresponding external groove 21 for circulation. When the internal hole 23 is not blocked, the water will directly flow into the water outlet groove 31 through the external groove 21 and be discharged, and then complete a cycle. When the resistance is low, less water will flow into the internal groove 22 for circulation, and the heat dissipation capacity at this time is low. When the internal hole 23 is completely blocked, the water can only circulate through the internal groove 22 before entering the external groove 21 for a large circle circulation. At this time, the heat dissipation capacity is enhanced, thereby improving the heat dissipation effect. Therefore, when the battery body 11 generates a lot of heat, a strong heat dissipation capacity is required, and a large circle circulation is required. When the heat is small, only the outer circle circulation is required.

[0036] Since the rotating sleeve 25 is installed in the control tube 24, the rotating sleeve 25 will be pressed against the internal hole 23, and then the insertion ring 213 is inserted into the control tube 24, and the sealing sleeve 26 is threadedly connected in the control tube 24 so that the sealing sleeve 26 is pressed on the rotating sleeve 25 to complete the sealing process, and the threaded connection of the threaded rod 214 ensures the stability of the double-side blocks 29, so that the gap between the two double-side blocks 29 is between the vertical hole 27 and the semicircular groove 28, and the double-side blocks 29 close to the memory spring 210 are in a connected state, so that the cooling water will flow into the space of the memory spring 210. During the period of time, the temperature of the cooling water will be transferred to the memory spring 210. When the temperature of the battery body 11 increases, the temperature of the cooling water will increase. Since the memory spring 210 is made of memory metal, it will expand and then push the double-sided block 29 close to the side of the memory spring 210 to fit into the vertical hole 27, and then reduce the diameter of the vertical hole 27 to reduce the flow rate passing through it. Therefore, the cooling water will enter the large circle circulation, thereby improving the heat dissipation ability and ensuring the safety of the battery body 11. When the temperature drops, the opening degree of the vertical hole 27 will be restored, thereby completing the heat dissipation cycle.

[0037] See also Figures 7 to 9The connection mechanism includes a water outlet groove 31 and a water inlet groove 32 provided on the water cooling plate 12, and the two ends of each external groove 21 are respectively connected to the water inlet groove 32 and the water outlet groove 31. The connection mechanism also includes a water outlet pipe 33 installed on the water outlet groove 31 and a water inlet pipe 34 installed on the water inlet groove 32. The water inlet pipe 34 and the water outlet pipe 33 are respectively fixedly installed with an external sleeve 35, and each external sleeve 35 is respectively slidably connected to an external pipe 36. The external pipe 36 is connected to the external water supply equipment. Two sealing rings 37 are installed on the external pipe 36. Two embedded grooves 38 are provided on the external sleeve 35. The sealing ring 37 is inserted into the embedded groove 38. A vertical groove 39 is provided on the external sleeve 35. The external folding plate 310 is slidably connected in the vertical groove 39. One end of the external pipe 36 is rotatably installed An outer folding plate 310 is installed, and the other end of the external tube 36 is rotatably connected to the inner folding plate 311, and a push sleeve 312 is threadedly connected to the external sleeve 35. A follower block 313 is installed on the outer folding plate 310. When in a sealed state, the push sleeve 312 abuts against the follower block 313, and a rotating shaft 314 is rotatably connected to the inner folding plate 311. A side groove 315 is provided in the outer folding plate 310, and it is rotatably and slidably connected in the side groove 315. An intermediate spring 316 is fixedly installed on the rotating shaft 314, and the other end of the intermediate spring 316 is connected in the outer folding plate 310. An unfastening sleeve 317 is slidably installed on the external sleeve 35, and a plurality of top blocks 318 are installed on the unfastening sleeve 317. The top blocks 318 are slidably connected in the vertical groove 39, and each top block 318 is respectively provided with a rounded corner 319.

[0038] When the external pipe 36 needs to be connected to the water cooling plate 12, the external pipe 36 is first inserted into the external sleeve 35, and then the plurality of follower blocks 313 are inserted into the external sleeve 35, and the seal ring 37 is inserted into the embedding groove 38, and the outer folding plate 310 can be ejected through the vertical groove 39. Since the side groove 315 is equipped with an intermediate spring 316, the inner folding plate 311 can slide along the side groove 315 under the action of the intermediate spring 316, so that the inner folding plate 311 and the outer folding plate 310 are pushed up at the same time, and the intermediate spring 316 will not cause the inner folding plate 311 to slide along the side groove 315. The plate 311 and the outer folding plate 310 are in a vertical state, which will only make the inner folding plate 311 and the outer folding plate 310 close to a vertical state. At this time, the multiple follower blocks 313 extend out of the vertical groove 39, and then the push sleeve 312 is rotated. Since the push sleeve 312 is threadedly connected to the external sleeve 35, the thrust is then transmitted to the multiple follower blocks 313 through the thrust bearing. At this time, under the action of the thrust, the inner folding plate 311 and the outer folding plate 310 are in a vertical state, and then the corresponding sealing force is applied to the insertion groove and the sealing ring 37, thereby ensuring the stability of use, and then the cooling process can be carried out.

[0039] When the connection needs to be released, it is only necessary to push the release sleeve 317, and then make the rounded corner 319 press against the outer folding plate 310. Since the inner folding plate 311 and the outer folding plate 310 are not in a vertical state when no force is applied, the rotating shaft 314 can slide in the side groove 315 so that the middle spring 316 is compressed, so that the inner folding plate 311 is sleeved in the outer folding plate 310. The diameter of the multiple follower blocks 313 is smaller than the inner diameter of the external sleeve 35, so the external tube 36 can be pulled out, thereby completing the release process.

[0040] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
