Description

Technical Field

[0001] The invention relates to the technical field of energy storage battery cooling, in particular to an industrial energy storage lithium battery cooling mechanism and an energy storage lithium battery. Background Art

[0002] With the continuous advancement of smart grid construction and power system reform, the importance of new energy battery energy storage technology has become increasingly prominent. Among them, lithium batteries play an important role in energy storage control systems, driving the rapid development of the lithium battery industry.

[0003] However, when using lithium batteries, a large amount of heat will be generated during the charging and discharging process, and heat will accumulate in the energy storage box. This requires attention to the ambient temperature of the lithium battery to ensure that it is in a stable state. If the ambient temperature is not properly controlled, the lithium battery may explode, catch fire and other accidents, posing a serious safety hazard. Therefore, when the energy storage battery is integrated, installed and used, it is necessary to add a cooling mechanism at the bottom of each energy storage battery to complete the active cooling of the energy storage battery and ensure stable operation.

[0004] A flame-retardant liquid-cooled new energy storage cabinet disclosed in a patent application with reference publication number CN118017090B, in which a cooling mechanism is added to the bottom of the energy storage battery pack, a first cooling chamber is added on the basis of the heat-conducting flat tube, and the heat-conducting flat tube is cooled intermittently, so that the heat-conducting liquid can be kept at a low temperature, so that the battery body can exchange more heat when in contact with the heat-conducting liquid, thereby improving the heat dissipation efficiency.

[0005] The above energy storage cabinet can complete the cooling process of the energy storage battery pack through the cooperation of the heat-conducting flat tubes and the circulation mechanism. However, the cooling mechanism of the energy storage battery pack does not flexibly and automatically control the flow of the water-cooling liquid. When the water-cooling liquid flows in the cooling mechanism, the water-cooling liquid is prone to gasification, resulting in flow interruption and local water shortage in the cooling mechanism. At the same time, when the water pressure is too low, the cooling effect of the cooling mechanism will be reduced, which will reduce the local cooling effect of the energy storage battery pack and cause uneven cooling, which will affect the cooling accuracy and the operation of the energy storage battery pack.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention completes multiple interceptions of the water-cooling liquid in the temporary storage cylinder through the cooperation of the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism, so that the water-cooling plate obtains a stable cooling state, ensures the cooling consistency, and avoids the situation where uneven cooling causes damage to the energy storage lithium battery, thereby completing the stable control of the water-cooling liquid and avoiding the problem of poor interception force.

At the same time, the slider links the traveling gear to obtain a forward movement amount. Under the coordinated transmission of the traveling gear, the No. 1 tooth plate and the No. 2 tooth plate, the No. 2 plate is driven to obtain a superimposed movement amount, so that the interception strength of the No. 2 opening and closing mechanism is greater than that of the No. 1 opening and closing mechanism. With such a design, the cooperation between the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism can obtain a stable interception state, which is convenient for the staff to flexibly adjust and control the interception strength, thereby controlling the water-cooled plate to obtain a stable cooling state;

[0022] 3. The present invention is provided with a synchronization mechanism to mesh the limit tooth plate with the connecting rack, and a certain thrust is applied to the limit tooth plate through a strong spring, so that the limit tooth plate and the connecting rack are meshed, and then the manual slide is operated to pull the synchronization arm upward under the connection between the limit tooth plate and the connecting rack, and pull the No. 2 partition upward. Since a linkage rod is installed between the No. 1 partition and the No. 2 partition, under the limitation of the retaining ring, the No. 1 partition follows the No. 2 partition and moves up synchronously, thereby completing the simultaneous opening of the No. 1 partition and the No. 2 partition, and the water-cooling liquid is not intercepted at this time.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A No. 1 opening and closing mechanism is installed between the No. 1 partition 6 and the No. 2 partition 7, and the No. 1 opening and closing mechanism is used to control the opening and closing of the No. 2 space 72. A No. 2 opening and closing mechanism is installed between the No. 2 partition 7 and the temporary storage tube 5, and the No. 2 opening and closing mechanism is used to control the opening and closing of the No. 3 space 73. The No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism complete linkage cooperation. A differential adjustment mechanism is added to the No. 2 opening and closing mechanism, and the differential adjustment mechanism is respectively coordinated with the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism. The differential fine-tuning action of the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism is completed through the differential adjustment mechanism, and a synchronization mechanism is installed on the temporary storage tube 5, and the synchronization mechanism is used to complete the synchronous opening and closing operation of the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism;

[0044] Among them, a sealing cover 8 is detachably installed on the open side of the temporary storage tube 5 by bolts, and an inlet pipe 9 is connected and installed on the other side of the temporary storage tube 5. The inlet pipe 9 is detachably and sealedly connected to the outlet pipe 4. The No. 1 partition 6 and the No. 2 partition 7 are both slidably sealed with the inner wall of the temporary storage tube 5. A flow channel 10 is opened through the bottom of the No. 1 partition 6 and the No. 2 partition 7, and two blocking plates 11 are correspondingly arranged at the bottom of the temporary storage tube 5. The two blocking plates 11 respectively cooperate with the flow channels 10 of the No. 1 partition 6 and the No. 2 partition 7 to complete the blocking. A main pipe 12 is installed at intervals at the bottom of the temporary storage tube 5, a No. 1 pipe 13 is connected and installed at the bottom of the No. 2 space 72, and a No. 2 pipe 14 is connected and installed at the bottom of the No. 3 space 73. The No. 1 pipe 13 and the No. 2 pipe 14 are both connected with the main pipe 12, and solenoid valves for controlling the opening and closing of the No. 1 pipe 13 and the No. 2 pipe 14 are installed at the ends of the No. 1 pipe 13 and the No. 2 pipe 14, and a connector is connected to one end of the main pipe 12;

[0045] In the embodiment of the present invention, the No. 1 opening and closing mechanism includes a No. 1 adjusting member 15 installed on one side of the No. 2 partition 7, and the No. 2 partition 7 is detachably in contact with the No. 1 adjusting member 15, and the No. 1 adjusting member 15 is detachably fixedly connected to the inner wall of the temporary storage tube 5 through a bracket, and a No. 1 adjusting area 16 is provided on the No. 1 adjusting member 15, and a No. 1 plate 17 is slidably engaged with the side of the No. 1 partition 6 in the No. 1 adjusting area 16, and a No. 2 plate 18 is slidably engaged with the side of the No. 1 plate 17 in the No. 1 adjusting area 16, and a No. 2 plate 18 is slidably engaged with the side of the No. 1 plate 17 in the No. 1 adjusting area 16, and an No. 1 arm 19 is concentrically installed on the No. 1 partition 6 toward the No. 2 partition 7, and the front end of the No. 1 arm 19 slides through the No. 1 adjusting member 15 The front end extends into the No. 1 adjustment area 16, and the No. 1 arm 19 is fixedly connected to the No. 1 plate 17, and the front end of the No. 1 arm 19 slides through the No. 2 plate 18, and a No. 1 spring 20 is sleeved on the outside of the No. 1 arm 19, and the No. 1 spring 20 is located between the No. 1 plate 17 and the No. 2 plate 18, and a space for the No. 1 arm 19 to telescopically move is provided in the No. 1 adjustment area 16, and a linkage rod 21 is added on one side of the No. 2 partition 7, and the front end of the linkage rod 21 slides through the No. 1 partition 6, and a retaining ring 22 is detachably sleeved on the front end of the linkage rod 21, and the retaining ring 22 is used to complete the limit of the No. 1 partition 6, and the linkage rod 21 can slide on the No. 1 partition 6;

[0046] It is worth noting that: when the water-cooling liquid is intercepted once: by providing a No. 1 opening and closing mechanism, the water-cooling liquid enters from the inlet pipe 3 and is discharged from the outlet pipe 4 under the circulation of the water-cooling liquid, thereby completing repeated cycle cooling. When the cooling accuracy of the water-cooling plate 1 decreases, the water-cooling liquid is sent into the No. 1 space 71 through the introduction pipe 9 for temporary storage, so that the pressure of the water-cooling liquid in the water-cooling plate 1 increases, prompting the water-cooling liquid to fill the water-cooling channel 2, thereby completing a stable cooling process, avoiding the problem of local lack of cooling liquid interfering with the cooling accuracy, and ensuring the stable operation of the energy storage lithium battery 46. When the pressure of the water-cooling liquid in the No. 1 space 71 gradually increases, the No. 1 partition 6 is pushed to move. During the movement of the No. 1 partition 6, the No. 1 arm 19 is linked to slide in the No. 1 adjustment area 16. Since the No. 1 spring 20 is limited between the No. 1 plate 17 and the No. 2 plate 18, the displacement of the No. 1 partition 6 is limited by the No. 1 spring 20. At this time, the flow channel 10 on the No. 1 partition 6 is separated from the blocking plate 11, and the water-cooling liquid is drained into the No. 2 space 72 to complete the pressure relief. At this time, if the predetermined interception effect is achieved, the No. 1 pipe 13 of the No. 2 space 72 can be opened, and the water-cooling liquid can be discharged through the main pipe 12;

[0047] In the embodiment of the present invention, the No. 2 opening and closing mechanism includes a No. 2 adjusting member 23 that is penetrated at the center of the sealing cover 8, and the No. 2 adjusting member 23 is arranged in parallel with the No. 1 adjusting member 15, and a No. 2 adjusting area 24 is penetrated and opened on the side of the No. 2 adjusting member 23 close to the No. 2 partition 7, and a No. 3 plate 25 is slidably engaged with the side of the No. 2 partition 7 in the No. 2 adjusting area 24, and a No. 4 plate 26 is slidably engaged with the side of the No. 3 plate 25 in the No. 2 adjusting area 24, and a No. 2 arm 27 is concentrically installed on the side of the No. 2 partition 7 facing the No. 2 adjusting member 23, and the No. 2 arm 27 slides through the No. 2 adjusting member 23 front end and extends into the No. 2 adjustment area 24, and the No. 2 arm 27 is fixedly connected to the No. 3 plate 25, and the front end of the No. 2 arm 27 slides through the No. 4 plate 26, and a No. 2 spring 28 is sleeved on the outside of the No. 2 arm 27, the No. 2 spring 28 has the same initial elastic coefficient as the No. 1 spring 20, and the No. 1 spring 20 has the same initial length as the No. 2 spring 28, and the No. 1 adjustment area 16 has the same length as the No. 2 adjustment area 24, and the No. 2 spring 28 is located between the No. 3 plate 25 and the No. 4 plate 26, and a space for the No. 2 arm 27 to telescopically move is provided in the No. 2 adjustment area 24;

[0048] It is worth noting that when the water-cooling liquid is intercepted for the second time: by providing a No. 2 opening and closing mechanism, if the predetermined cooling effect cannot be obtained after interception by the No. 1 partition 6, the No. 1 pipe 13 will be closed at this time, and the subsequent water-cooling liquid will be collected in the No. 2 space 72. When the water-cooling liquid is intercepted to a predetermined state, the No. 2 partition 7 is pushed to move. During the movement of the No. 2 partition 7, the No. 2 arm 27 is linked to slide in the No. 2 adjustment area 24. Since the No. 2 spring 28 is restricted between the No. 3 plate 25 and the No. 4 plate 26, the position of the No. 2 partition 7 is restricted by the No. 2 spring 28. At this time, the flow channel 10 on the No. 2 partition 7 is separated from the sealing plate 11 to drain the water-cooling liquid into the No. 3 space 73 to complete the pressure relief action. At this time, the water-cooling liquid is discharged through the No. 2 pipe 14 to complete the subsequent circulation. The cooperation of the No. 1 partition 6 and the No. 2 partition 7 completes multiple interceptions of the water-cooling liquid, so that the water-cooling plate 1 obtains a stable cooling state.

[0049] Embodiment 2: Based on the differential adjustment mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the differential adjustment mechanism.

[0050] like Fig.10 and Fig.12 As shown, the differential adjustment mechanism includes a sliding area 29 that runs through the tail of the No. 2 adjustment member 23, a slider 30 is slidably engaged in the sliding area 29, and an adjusting screw 31 is threadedly screwed through the tail of the No. 2 adjustment member 23, a hand wheel is installed at the tail of the adjusting screw 31, and the front end of the adjusting screw 31 is rotatably connected to the side wall of the slider 30, a No. 1 push rod 32 is installed at the bottom of the slider 30, and the front end of the No. 1 push rod 32 corresponds to the sliding seal and passes through the sealing cover 8, the No. 2 partition plate 7 and the No. 2 plate 18. A No. 1 tooth plate 33 is installed on the top of the sliding area 29, and the No. 1 tooth plate 33 is slidably arranged with the slider 30, so that the slider 30 can complete the movement relative to the No. 1 tooth plate 33, and a travel gear 34 is rotatably installed on the top of the slider 30 through a bracket. The travel gear 34 moves with the slider 30, and two guide frames 35 are symmetrically installed at the tail of the No. 2 adjusting member 23. A No. 2 tooth plate 36 is slidably restricted on the two guide frames 35. Slideways are provided on both sides of the No. 2 tooth plate 36. The two guide frames 35 slide and engage in the slideways to complete the limit. The travel gear 34 is respectively engaged with the No. 1 tooth plate 33 and the No. 2 tooth plate 36. A No. 2 push rod 37 is installed at the front end of the No. 2 tooth plate 36. The front end of the No. 2 push rod 37 slides through the sealing cover 8 and is connected to the No. 4 plate 26. The No. 1 spring 20 and the No. 2 spring 28 are differentially compressed through the cooperation of the slider 30 with the No. 1 push rod 32 and the No. 2 push rod 37, so that the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism obtain interception capabilities of different strengths.

[0051] It is worth noting that: when differential adjustment is performed on the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism: by providing a differential adjustment mechanism, it is only necessary to rotate the adjustment screw 31 accordingly to push the slider 30 forward in the sliding area 29. When the slider 30 moves forward, the No. 1 push rod 32 is driven forward, and the No. 2 plate 18 is linked to move toward the No. 1 plate 17 through the forward movement of the No. 1 push rod 32. Under this path, the No. 1 spring 20 is compressed through the No. 2 plate 18, thereby completing the adjustment of the shutoff strength of the No. 1 opening and closing mechanism. At the same time, the slider 30 is linked with the travel gear 34 to obtain the forward movement amount. When the travel gear 34 moves forward, it is meshed and guided by the No. 1 tooth plate 33, so that the travel gear 34 is in the forward movement path. At the same time, it obtains a rotation state, so that When the running gear 34 rotates, it will push the No. 2 tooth plate 36 forward again, driving the No. 2 plate 18 to obtain a superimposed movement amount, so that the forward movement amount of the No. 2 tooth plate 36 is greater than the forward movement amount of the slider 30, and then the No. 4 plate 26 is pushed by the No. 2 push rod 37. The movement amount of the No. 4 plate 26 is greater than the movement amount of the No. 2 plate 18. Therefore, the compression amount of the No. 4 plate 26 on the No. 2 spring 28 is greater than the compression amount of the No. 1 spring 20, so that the shut-off force of the No. 2 opening and closing mechanism is greater than that of the No. 1 opening and closing mechanism. With this design, the cooperation between the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism can obtain a stable shut-off state, which is convenient for the staff to flexibly adjust and control the shut-off force, thereby controlling the water-cooled plate 1 to obtain a stable cooling state.

[0052] Embodiment 3: Based on the synchronization mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the synchronization mechanism.

[0053] like Fig.13 and Fig.14 As shown, the synchronization mechanism includes a synchronization arm 38 installed on one side of the second partition 7, and the corresponding sliding seal of the synchronization arm 38 passes through the sealing cover 8. A manual slide 39 is installed on the sealing cover 8 on one side of the synchronization arm 38. The manual slide 39 consists of a lifting frame, a screw and a screw nut. The screw is rotatably installed in the lifting frame. The screw nut is slidably engaged in the lifting frame and sleeved on the outside of the screw. The position of the screw nut is adjusted by the screw. The screw nut is connected to the sliding frame 40, and a handle is installed on the top of the lifting frame. The screw is rotated by the handle. A sliding frame 40, in which a telescopic member 41 is slidably engaged, a limit tooth plate 42 is installed at the front end of the telescopic member 41, and a connecting rack 43 is arranged on one side of the synchronization arm 38, the limit tooth plate 42 is meshed and connected with the connecting rack 43, and two strong springs 44 are installed between the telescopic member 41 and the bottom of the sliding frame 40, the two strong springs 44 are used to push the limit tooth plate 42 to mesh with the connecting rack 43, and pull arms 45 are symmetrically installed on both sides of the telescopic member 41, and the displacement operation of the telescopic member 41 is completed by the pull arms 45, and the limit tooth plate 42 is separated from the connecting rack 43 and does not contact under normal conditions;

[0054] It is worth mentioning that: when the No. 1 partition 6 and the No. 2 partition 7 are opened at the same time: by providing a synchronization mechanism, under normal circumstances, the limit tooth plate 42 is separated from the connecting rack 43, and the limit tooth plate 42 will not interfere with the displacement of the synchronization arm 38 under normal circumstances. When the No. 1 partition 6 and the No. 2 partition 7 are opened at the same time, in order to ensure the convenience of adjustment, the differential adjustment mechanism is first reset to a predetermined position to facilitate the subsequent operation of the synchronization mechanism. It is only necessary to operate the manual slide 39 to drive the limit tooth plate 42 to move up to the connecting rack 43 area, and then apply external force to the pulling arm 45 to make the telescopic member 41 contract in the sliding frame 40, compress the strong spring 44, and then the limit tooth plate 42 and The connecting rack 43 is meshed, and a certain thrust is applied to the limit tooth plate 42 through the strong spring 44, so that the limit tooth plate 42 and the connecting rack 43 are meshed, and the manual slide 39 is subsequently operated to pull the synchronization arm 38 upward under the connection between the limit tooth plate 42 and the connecting rack 43, and pull the No. 2 partition 7 upward. Since a linkage rod 21 is installed between the No. 1 partition 6 and the No. 2 partition 7, under the limitation of the retaining ring 22, the No. 1 partition 6 moves up synchronously with the No. 2 partition 7, so as to complete the simultaneous opening of the No. 1 partition 6 and the No. 2 partition 7. At this time, the water-cooling liquid is not intercepted. When interception is required later, it is only necessary to separate and reset the limit tooth plate 42 and the connecting rack 43.

[0055] Embodiment 4: An energy storage lithium battery, the energy storage lithium battery 46 is cooled by a cooling mechanism, the energy storage lithium battery 46 is mounted on the cooling mechanism, and the cooling mechanism is the above-mentioned cooling mechanism.

[0056] The present invention provides an industrial energy storage lithium battery cooling mechanism and an energy storage lithium battery, and the specific working principle is as follows: first, the temporary storage tube 5 is installed on the water cooling plate 1, and the inlet pipe 9 is connected with the outlet pipe 4, so that the water-cooling liquid flowing in the water cooling plate 1 can be accurately introduced into the temporary storage tube 5, and the temporary storage box is divided into a first space 71, a second space 72 and a third space 73 through a first partition plate 6 and a second partition plate 7. After the subsequent water-cooling liquid is drawn out through the outlet pipe 4, it first enters the first space 71 for temporary storage;

[0057] A No. 1 opening and closing mechanism is added to the No. 1 partition 6, and the No. 1 opening and closing mechanism is used to actively limit the No. 1 partition 6, and the No. 1 space 71 is used to intercept the water-cooling liquid, which can actively limit the flow of the water-cooling liquid, so that the water-cooling liquid can fill the water-cooling channel 2 of the water-cooling plate 1, and the residence time of the water-cooling liquid can be controlled, thereby effectively avoiding the problem of local water-cooling liquid loss in the water-cooling channel 2, ensuring the cooling accuracy of the water-cooling plate 1, ensuring the cooling consistency, avoiding the situation where uneven cooling causes damage to the energy storage lithium battery 46, and in the No. 2 With the cooperation of the opening and closing mechanism, the secondary interception of the water-cooling liquid is completed in the temporary storage tube 5, so as to complete the stable control of the water-cooling liquid and avoid the problem of poor interception force. The No. 1 opening and closing mechanism can complete the follow-up opening with the No. 2 opening and closing mechanism, and the No. 1 opening and closing mechanism can be operated independently, which is convenient for the staff to freely adjust and use according to the use requirements. At the same time, the synchronous opening and closing operation of the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism can be completed through the synchronization mechanism, which is convenient for the staff to actively open and close the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism according to the operating status of the water-cooling plate 1, which is more practical and flexible.

[0058] In addition, the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism are synchronously controlled through the differential adjustment mechanism, and the interception force of the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism can be synchronously fine-tuned to adapt to different working conditions, and the difference adjustment between the No. 1 opening and closing mechanism and the No. 2 opening and closing mechanism can be completed, so that the interception force of the No. 2 opening and closing mechanism is greater than that of the No. 1 opening and closing mechanism, so as to obtain a more stable interception effect, which provides convenience for the operation of the staff and is conducive to the precise control of the cooling state of the water-cooled plate 1, thereby providing a good cooling state and ensuring the safe operation of the energy storage lithium battery 46.
