Description

Technical Field

[0001] The present application relates to the field of energy storage facilities, and in particular to an energy storage cabinet drainage device and an energy storage cabinet. Background Art

[0002] Currently, energy storage cabinets are key components in power systems and energy management, playing an important role in energy production, distribution and storage.

[0003] In the related art, the interior of the energy storage cabinet is divided into multiple areas, some of which are used to place battery modules, and some of which are used to place temperature control equipment such as air conditioners. The energy storage cabinet is prone to produce fluids inside when working. For example, during the temperature control process of the battery module, the air near it is prone to condensation due to the alternation of hot and cold; at the same time, the temperature control equipment is also prone to produce refrigerant during the temperature adjustment process.

[0004] However, the inventors realize that in actual use, the fluids generated in different areas inside the energy storage cabinet are processed separately, that is, the energy storage cabinet needs to process the fluids in multiple areas separately, resulting in low fluid cleaning efficiency inside the energy storage cabinet. Summary of the invention

[0005] One or more embodiments of the present application provide an energy storage cabinet drainage device and an energy storage cabinet to solve or at least partially alleviate the problem in the related art that the energy storage cabinet needs to process fluids in multiple areas respectively, resulting in low fluid cleaning efficiency inside the energy storage cabinet.

At the same time, since the pipe unit is arranged in the cabinet, the inside of the cabinet can be cooled during the flow of the fluid.

[0010] In some embodiments, the energy storage cabinet drainage device further includes a water pipe, one end of which is connected to the pipe unit at the uppermost end, and the other end of which is used to connect to the liquid cooling pipe.

[0011] In some embodiments, the energy storage cabinet drainage device further includes a switch assembly, and the switch assembly is provided at the connection point between the pipeline unit and the corresponding chamber.

[0015] In some embodiments, the inner wall of the lower portion of the water collecting trough structure is inclined; and / or the top of the water collecting trough structure is located inside the chamber, and at least one water inlet is provided on the side wall.

[0016] In some embodiments, the energy storage cabinet drainage device also includes a ramp plate, which constitutes a part of the bottom wall of the chamber, and the ramp plate is provided with a through hole, and the water collecting trough structure is arranged at the through hole; along the direction from close to the through hole to away from the through hole, the ramp plate is arranged to be inclined upward.

[0017] In a second aspect of the present application, an energy storage cabinet is provided, which adopts the following technical solution:

[0018] An energy storage cabinet comprises a cabinet body and the energy storage cabinet drainage device as described above, wherein the cabinet body is provided with at least two chambers from top to bottom, and a plurality of pipeline units of the energy storage cabinet drainage device are arranged in the cabinet body and are respectively connected with the bottoms of the plurality of chambers.

[0037] Figure 1 Schematic diagram of the installation of the energy storage cabinet drainage device 100 according to some embodiments of the present application.

[0038] Figure 2 Schematic diagram of an energy storage cabinet drainage device 100 according to some embodiments of the present application.

[0039] One or more embodiments of the present application disclose a drainage device 100 for an energy storage cabinet. Figure 1 , 2 The energy storage cabinet drainage device 100 includes at least two pipe units 101 and at least one collecting tank 102; the multiple pipe units 101 are respectively used to communicate with the bottoms of different chambers 201 of the cabinet 200; the multiple pipe units 101 are connected in sequence along the vertical direction, and the outlet end of the bottommost pipe unit 101 is connected to the collecting tank 102.

[0040] In at least one embodiment, reference Figure 1 , 2 The cabinet 200 is divided into three chambers 201 from top to bottom, namely the first chamber 2011, the second chamber 2012 and the third chamber 2013; one pipeline unit 101 is located in the second chamber 2012 and is connected to the bottom of the first chamber 2011, and the other pipeline unit 101 is located in the third chamber 2013 and is connected to the bottom of the second chamber 2012; the two pipeline units 101 are connected in the up and down directions, and the outlet end of the lowest pipeline unit 101 is connected to the collection tank 102.

[0041] By adopting the above technical solution, when the multiple chambers 201 inside the cabinet 200 generate fluids such as condensed water or water mist coming in through the air inlet window, the fluid will flow to the bottom of the chamber 201. Since the multiple pipe units 101 are used to be connected to the bottoms of different chambers 201 of the cabinet 200, the condensed water at the bottoms of different chambers 201 will flow to the corresponding pipe units 101. At the same time, since the multiple pipe units 101 are connected in sequence vertically, and the outlet end of the bottom pipe unit 101 is connected to the collecting tank 102, the fluid will eventually be collected in the collecting tank 102, which is convenient for unified treatment such as removal or recycling. Compared with separately treating the fluid in each area, the cleaning efficiency is effectively improved; at the same time, since the pipe unit 101 is arranged in the cabinet 200, the inside of the cabinet 200 can be cooled during the flow of the fluid.

[0042] It should be understood that, in this embodiment, the shapes and sizes of the plurality of pipeline units 101 may be the same or different, which is not limited here and depends on actual needs.

[0043] It should be understood that in this embodiment, when some chambers 201 inside the cabinet 200 do not produce fluid, it is not necessary to set up the pipeline unit 101 to connect therewith. In other words, when the chamber 201 produces fluid, the pipeline unit 101 can be set up to connect therewith.

[0044] In some embodiments, in two adjacent pipeline units 101 , the outlet end of the first pipeline unit 101 and the inlet end of the second pipeline unit 101 are disposed correspondingly up and down.

[0045] In at least one embodiment, two adjacent pipeline units 101 are arranged along the vertical interval, and the outlet end of the pipeline unit 101 located above is arranged correspondingly to the inlet end of the pipeline unit 101 located below. The upper and lower corresponding arrangement here means that the contour shape of the outlet end of the pipeline unit 101 located above and the contour shape of the inlet end of the pipeline unit 101 located below overlap in the upper and lower directions.

[0046] In this way, the use of elbows can be reduced to reduce the resistance of the fluid during the flow, thereby facilitating the discharge of water from the upper pipe unit 101; in addition, this layout also helps to maintain the continuity of fluid flow; finally, the corresponding pipe units 101 arranged above and below can effectively utilize space and save floor space.

[0047] In other embodiments, in two adjacent pipeline units 101, the outlet end of the first pipeline unit 101 and the inlet end of the second pipeline unit 101 may also be staggered, that is, the outlet end of the first pipeline unit 101 and the inlet end of the second pipeline unit 101 do not overlap up and down.

[0048] In some embodiments, the energy storage cabinet drainage device 100 further includes a switch assembly 103 , and the connection point between the pipe unit 101 and the corresponding chamber 201 is provided with a switch assembly 103 .

[0049] In at least one embodiment, reference Figure 1 , 2 One pipeline unit 101 is located in the second chamber 2012, and the pipeline unit 101 is connected to the bottom of the first chamber 2011 at the top and a switch component 103 is provided at the connection point; the other pipeline unit 101 is located in the third chamber 2013 at the bottom, and the pipeline unit 101 is connected to the bottom of the second chamber 2012 in the middle and a switch component 103 is provided at the connection point.

[0050] In this way, a switch assembly 103 is provided at the connection point between the pipeline unit 101 and the corresponding chamber 201, so as to provide corresponding control capability, thereby opening or closing the corresponding pipeline assembly as needed.

[0051] Figure 3 for Figure 1 A partial enlarged view of point A in the middle.

[0052] Figure 4 for Figure 1 A partial enlarged view of point B in the middle.

[0053] In some embodiments, reference Figure 3 , 4 The switch assembly 103 includes a water collecting tank structure 1031 and a switch 1032. The inlet end of the water collecting tank structure 1031 is connected to the bottom of the chamber 201, and the outlet end of the water collecting tank structure 1031 is connected to the inlet end of the pipeline unit 101. The switch 1032 is used to open or close the outlet end of the water collecting tank structure 1031.

[0054] In at least one embodiment, the water collecting trough structure 1031 is arranged inside the bottom wall of the first chamber 2011 or the second chamber 2012, and the inlet end of the water collecting trough structure 1031 is connected to the bottom of the first chamber 2011 or the second chamber 2012, and the water outlet end of the water collecting trough structure 1031 is connected to the inlet end of the pipeline unit 101. Specifically, the water outlet end of the water collecting trough structure 1031 is provided with a connecting pipe 1034, and the pipeline unit 101 is sleeved on the connecting pipe 1034 and locked and sealed; the switch 1032 is used to open or close the outlet end of the water collecting trough structure 1031.

[0055] In this way, the inlet end of the water collecting trough structure 1031 is directly connected to the bottom of the chamber 201, which can ensure that the fluid flows into the water collecting trough structure 1031 for temporary storage; and its outlet end is connected to the inlet end of the pipeline unit 101, which ensures that the fluid can smoothly enter the pipeline unit 101, and the outlet end of the water collecting trough structure 1031 can be opened or closed by the switch component 103, thereby controlling whether the fluid enters the pipeline unit 101.

[0056] In some embodiments, the switch 1032 is a gravity ball, which is located in the water collecting tank structure 1031 and is used to open or close the outlet end of the water collecting tank structure 1031 under force; or, the switch 1032 includes a liquid level sensor and a control valve, which are electrically connected to the liquid level sensor, the liquid level sensor is arranged in the water collecting tank structure 1031, and the control valve is used to open or close the outlet end of the water collecting tank structure 1031.

[0057] In at least one embodiment, the switch 1032 is a gravity ball, which is arranged in the water collecting tank structure 1031. The gravity ball is used to open or close the outlet end of the water collecting tank structure 1031 under force. That is to say, when the water in the water collecting tank structure 1031 reaches a certain amount, the buoyancy of the water can drive the gravity ball to rise, thereby opening the outlet end of the water collecting tank structure 1031; when the water in the water collecting tank structure 1031 does not reach a certain amount, the buoyancy of the water cannot drive the gravity ball to rise, and the gravity ball closes the outlet end of the water collecting tank structure 1031 under the action of gravity.

[0058] In this way, the gravity ball switch provided in the water collecting tank structure 1031 can automatically adjust the opening and closing of the outlet end of the water collecting tank structure 1031 according to the change of water level. It does not rely on electric control, which not only saves costs but also reduces the failure rate.

[0059] In at least one embodiment, the switch 1032 includes a liquid level sensor and a control valve, wherein the control valve is a solenoid valve, the liquid level sensor and the solenoid valve are electrically connected, the liquid level sensor is disposed in the water collecting tank structure 1031, and the solenoid valve is used to open or close the outlet end of the water collecting tank structure 1031.

[0060] In this way, the switch 1032 composed of a liquid level sensor and a control valve can realize electronic control automation. The liquid level sensor can relatively accurately monitor the water level changes in the water collecting tank structure 1031. Once the water level reaches a preset value, the liquid level sensor sends a signal to the control valve to automatically open or close the outlet end of the water collecting tank structure 1031.

[0061] Figure 5 Schematic diagram of the switch assembly 103 according to some embodiments of the present application.

[0062] In some embodiments, reference Figure 5The inner wall of the lower part of the water collecting trough structure 1031 is inclined inward.

[0063] In at least one embodiment, the top of the water collecting trough structure 1031 is cylindrical and the lower part is conical, that is, the inner wall of the lower part of the water collecting trough structure 1031 is inclined relative to the vertical direction, and the inclination angle is not specifically limited and depends on actual needs.

[0064] Thus, after the fluid enters the water collecting trough structure 1031, since the inner wall of the lower part of the water collecting trough structure 1031 is tilted inward, the liquid level of the fluid in the lower part of the water collecting trough structure 1031 will rise rapidly, prompting the switch 1032 to respond quickly, thereby achieving rapid drainage.

[0065] In some embodiments, reference Figure 5 The top of the water collecting tank structure 1031 is located inside the chamber 201, and at least one water inlet 1033 is provided on the side wall.

[0066] In at least one embodiment, the top of the water collecting trough structure 1031 is located inside the chamber 201, generally 2 cm to 3 cm, and the top of the water collecting trough structure 1031 located in the chamber 201 is provided with a plurality of water inlets 1033, the number of which is determined according to actual needs, and the bottom wall of the water inlet 1033 is flush with or lower than the bottom wall of the chamber 201.

[0067] In this way, when the water collecting trough structure 1031 is installed, the top of the water collecting trough structure 1031 is located inside the chamber 201, that is, the top of the water collecting trough structure 1031 protrudes from the bottom wall of the chamber 201, which is convenient for sealing the connection between the water collecting trough structure 1031 and the chamber 201; at the same time, a water inlet 1033 is set on the side wall of the top of the water collecting trough structure 1031, which can facilitate the fluid in the chamber 201 to enter the interior of the water collecting trough structure 1031.

[0068] Figure 8 Schematic diagram of the bottom wall of the second chamber according to some embodiments of the present application.

[0069] Fig. 9 This is a schematic diagram of the bottom wall of the first chamber according to some embodiments of the present application.

[0070] In some embodiments, reference Figure 5 The energy storage cabinet drainage device 100 also includes a ramp plate 104, which constitutes a part of the bottom wall of the chamber 201. The ramp plate 104 is provided with a through hole 1041, and the water collecting trough structure 1031 is arranged at the through hole 1041; along the direction from close to the through hole 1041 to away from the through hole 1041, the ramp plate 104 is arranged to be inclined upward.

[0071] In at least one embodiment, the ramp plate 104 is disposed inside the chamber 201 and serves as the top of the bottom wall of the chamber 201. The ramp plate 104 is provided with a through hole 1041, and the water collecting trough structure 1031 is disposed at the through hole 1041. In the direction from close to the through hole 1041 to away from the through hole 1041, the ramp plate 104 is tilted upward, and the tilt angle ranges from 179 degrees to 180 degrees. That is, the through hole 1041 is at the lowest position of the bottom wall of the chamber 201, for example, Figure 8 As shown, the ramp plate 104 of the bottom wall of the second chamber 2012 is divided into a first ramp plate 1041 and a second ramp plate 1042. The first ramp plate 1041 is tilted downward from the rear to the front, and the second ramp plate 1042 is tilted downward from the front to the rear. A guide rod 107 is provided between the first ramp plate 1041 and the second ramp plate 1042. A through hole 1041 is provided at the intersection of the first ramp plate 1041 and the second ramp plate 1042. The through hole 1041 is located at the right end of the guide rod 107, and the upper end surface of the guide rod 107 is tilted downward from left to right.

[0072] So, refer to Figure 8 As shown by the arrow, after the fluid is generated inside the chamber 201, the fluid first flows toward the bottom wall of the chamber 201, and the fluid on the first ramp plate 1041 and the second ramp plate 1042 first flows toward the guide rod 107, and then the fluid flows to the through hole 1041 through the guidance of the guide rod 107, thereby prompting the fluid to flow to the lowest position of the chamber 201, that is, the position of the through hole 1041. Since the water collecting trough structure 1031 is arranged at the through hole 1041, it is convenient for the fluid to enter the water collecting trough structure 1031. At the same time, during the flow of the fluid, the electrical equipment at the bottom of the second chamber 2012, such as the battery module, can be cooled.

[0073] Furthermore, in order to better distribute the fluid for cooling, a partition plate 108 may be provided to separate the first ramp plate 1041 and the second ramp plate 1042 into a plurality of regions. For example, the difference between the ramp plate 104 of the bottom wall of the first chamber 2011 and the ramp plate 104 of the bottom wall of the second chamber 2011 is that the first ramp plate 1041 is divided into a first region 10411, a second region 10412, a third region 10413 and a fourth region 10414 by the partition plate 108. , the first area 10411, the second area 10412, the third area 10413 and the fourth area 10414 are all arranged to be tilted downward from the rear to the front; the second slope plate 1042 is divided into the fifth area 10421, the sixth area 10422, the seventh area 10423 and the eighth area 10424 by the partition plate 108, that is, the fifth area 10421, the sixth area 10422, the seventh area 10423 and the eighth area 10424 are all arranged to be tilted downward from the front to the rear. At the same time, in order to facilitate the flow of fluid, a water outlet is provided at the junction of the partition plate 108 and the guide rod 107; water outlets are also provided between the mutually isolated areas. The fluid flow path can refer to Fig. 9 Indicated by the arrow.

[0074] Furthermore, the ramp plate 104 and the water inlet 1033 on the water collecting trough structure 1031 form a step structure, that is, the ramp plate 104 is higher than the bottom wall of the water inlet 1033 and lower than the top wall of the water inlet 1033 .

[0075] In some embodiments, reference Figure 1 The energy storage cabinet drainage device 100 also includes a fastener 105 , and the pipeline unit 101 is fixed inside the cabinet body 200 through the fastener 105 .

[0076] In at least one embodiment, the pipeline unit 101 is a hose, which is connected to other pipelines through a clamp or a quick-change head; the fastener 105 is a nylon tie, so that the pipeline unit 101 can be tied to the fixed plate inside the cabinet 200 through the nylon tie, which greatly reduces the probability of the pipeline unit 101 shaking.

[0077] In at least one embodiment, a placement groove is provided on the bottom outer wall of the cabinet 200, and the collection tank 102 is pull-out arranged in the placement groove.

[0078] In this way, after the fluid in the collection tank 102 reaches a certain amount, the collection tank 102 can be drawn out from the placement tank in the cabinet 200 to achieve cleaning.

[0080] Figure 7 Schematic diagram of a drainage device for an energy storage cabinet according to some embodiments of the present application Figure 2 .

[0081] In some embodiments, in at least one pipeline unit 101, the pipeline unit 101 includes a plurality of first bent tubes 1011 and a plurality of first inclined tubes 1012, and the plurality of first bent tubes 1011 and the plurality of first inclined tubes 1012 are vertically staggered and connected in sequence.

[0082] In at least one embodiment, reference Figure 6 , 7 A pipeline unit 101 is located in the middle second chamber 2012, which includes three first bent tubes 1011 and three first inclined tubes 1012. The three first bent tubes 1011 and the three first inclined tubes 1012 are vertically staggered and connected in sequence to form an S-shaped reciprocating pipeline structure.

[0083] In this way, when the battery module is installed in the second cavity 2012, the pipeline unit 101 can cool the battery module in the up-down direction and the front-back direction.

[0084] In other embodiments, the number of the first bent tubes 1011 and the first inclined tubes 1012 may also be four, five or six, which is not limited here and depends on actual needs.

[0085] Furthermore, if Figure 5 , 6 As shown, the pipe unit 1012 of the second chamber 2012 in the middle is directly connected to the upper end of the pipe unit 101 of the third chamber 2013 at the bottom through a pipe. When the fluid in the second chamber 2012 enters the pipe unit 101 of the third chamber 2013, part of the fluid can flow back to the pipe unit 1012 of the second chamber 2012 in the middle, thereby cooling down.

[0086] In some embodiments, the energy storage cabinet drainage device further includes a water pipe 106 , one end of which is connected to the uppermost pipe unit 101 , and the other end of which is used to communicate with the liquid cooling pipe.

[0087] In at least one embodiment, the water pipe 106 can be a straight pipe or a curved pipe, which is not limited here and depends on actual needs. Figure 5 As shown, it serves to connect the uppermost pipe unit 101 with the liquid cooling pipe.

[0088] In this way, after the fluid in the first chamber 2011 at the top enters the corresponding first pipeline unit 101 , it can also flow to the liquid cooling pipe through the water pipe 106 , thereby realizing the recycling of the fluid in the first chamber 2011 at the top.

[0089] Furthermore, the energy storage cabinet drainage device also includes a switch control valve 109 , which is connected to the water pipe 106 and is used to open or close the flow path of the water pipe 106 .

[0090] In this embodiment, the switch control valve 109 is a manual valve or a solenoid valve. There is no limitation here, and it depends on actual needs. In the early debugging process, the flow path of the water pipe 106 can be cut off by the switch control valve 109 to achieve the closure of the branch.

[0091] It should be understood that when the switch control valve 109 is not provided to open or close the flow path of the water pipe 106, during the early debugging process, the water pipe 106 can be blocked to achieve the closure of the branch.
