Description

Technical Field

[0001] This application relates to the technical field of energy storage systems, and in particular to a drainage device and an energy storage system. Background Technology

[0002] Currently, energy storage systems, such as air conditioners in energy storage cabinets, generate condensate during normal use, condensate overflowing from cooling pipes in battery compartments during maintenance, and wastewater from cleaning the interior during maintenance. These water flows are usually discharged outside the energy storage cabinet using drainage devices to reduce humidity inside the energy storage cabinet.

[0003] In related technologies, the drainage device mainly includes a manifold and a drain pipe. The manifold is fixedly installed on the bottom plate of the energy storage cabinet to receive the various water flows mentioned above. The drain pipe is connected to one end of the manifold and is used to discharge the water flow collected by the manifold outside the energy storage cabinet.

[0004] However, the inventors realized that in actual use, the water flow in the above-mentioned manifold is relatively slow to be discharged outward through the drain pipe by its own gravity, or the drainage system will only be passively activated to perform drainage after the water flow in the manifold has accumulated to a certain extent, resulting in low water flow discharge efficiency in the manifold. Utility Model Content

[0005] This application provides a drainage device and an energy storage system in one or more embodiments to solve or at least partially alleviate the problem of low water discharge efficiency in energy storage systems in the related art.

[0006] The first aspect of this application provides a drainage device, which adopts the following technical solution:

[0007] A drainage device, comprising:

[0008] A water collection structure is provided to collect water generated by the energy storage system, and the water collection structure is provided with a drain outlet.

[0009] The drain pipe includes an inlet section, a lifting section, and an outlet section connected in sequence. The inlet section is connected to the drain outlet. The inner wall of the highest point of the lifting section is higher than the inner wall of the highest point of the inlet section. The axis of the outlet section is lower than the axis of the inlet section, so as to form a negative pressure siphon effect at the lifting section.

[0010] In some embodiments, the distance between the highest point of the inner bottom wall of the lifting section and the axis of the water inlet section is greater than or equal to the inner diameter of the water inlet section.

[0011] In some embodiments, the water collection structure includes a water collection tank, the end of the water collection tank along a first direction is provided with the drain outlet, and the bottom wall of the water collection tank slopes downward toward the drain outlet along the water flow direction.

[0012] In some embodiments, the water collection structure further includes a water collection section, which is fixed inside the water collection tank, and the cross-sectional area of ​​the water collection section gradually decreases along the water flow direction and is connected to the drain outlet.

[0013] In some embodiments, the water collection section includes at least one water collection plate, which is connected to the side wall of the water collection tank and converges toward the drain outlet.

[0014] In some embodiments, the water collection structure further includes a water collection section, which is fixed to the top of the water collection tank;

[0015] The water collection part is provided with an opening, and the opening is connected to the water collection tank;

[0016] The end of the water collection section along the second direction is positioned higher than the edge of the opening, and a guide surface is provided between the end of the water collection section along the second direction and the edge of the opening.

[0017] In some embodiments, the water collection structure further includes a drain plate disposed at the top of the water collection tank, and the drain plate is provided with drain holes.

[0018] In some embodiments, the water collection tank includes a water collection tank body and a support portion, the top of the water collection tank body is connected to the support portion, and the drain plate is detachably installed via the support portion.

[0019] In some embodiments, the top of the water collection portion passes through the support portion and is attached to the bottom of the drain plate.

[0020] In some embodiments, the water collection structure further includes a drain plate, which is disposed at the top of the water collection tank;

[0021] The area corresponding to the water collection part of the leaking plate is sealed to the edge of the opening. The area of ​​the leaking plate away from the water collection part has a notch on its edge, and the notch is connected to the water collection tank.

[0022] Compared with related technologies, one or more embodiments of this application include at least one of the following beneficial technical effects:

[0023] The drainage device may include a water collection structure and a drain pipe. The water collection structure collects water flow within the energy storage system. Since the inlet section of the drain pipe is connected to the outlet of the water collection structure, water flow within the water collection structure enters the inlet section through the outlet. Because the inner wall of the highest point of the lifting section is higher than the inner wall of the highest point of the inlet section, negative pressure is created at the lifting section as the water flow passes through it, generating a siphon effect. The axial position of the outlet section is lower than that of the inlet section; in other words, the outlet section is lower than the inlet section. This lower outlet section accelerates water flow and maintains continuous siphoning, not only quickly discharging water from the water collection structure but also using negative pressure to clean the water collection structure, thereby improving the discharge efficiency of the water flow within the water collection structure.

[0024] A second aspect of this application provides an energy storage system, which adopts the following technical solution:

[0025] An energy storage system includes a drainage device as described above.

[0026] Since the energy storage system includes a drainage device, the energy storage system has at least all the technical effects of the drainage device, which will not be elaborated here. Attached Figure Description

[0048] Figure 1 This is a schematic diagram of the structure of a drainage device according to some embodiments of this application. Figure 2 for Figure 1 Enlarged view of section A.

[0049] One or more embodiments of this application disclose a drainage device. (See also...) Figure 1 and Figure 2 Drainage device, including:

[0050] Water collection structure 2, which is used to collect water generated by the energy storage system, and the water collection structure 2 is provided with a drain outlet 2110;

[0051] The drain pipe 1 includes an inlet section 11, a lifting section 12, and an outlet section 13 connected in sequence. The inlet section 11 is connected to the drain outlet 2110. The inner wall of the highest point of the lifting section 12 is higher than the inner wall of the highest point of the inlet section 11. The axis of the outlet section 13 is lower than the axis of the inlet section 11, so as to form a negative pressure siphon effect at the lifting section 12.

[0052] Specifically, the water collection structure 2 can be fixedly installed at the bottom of the energy storage system, such as an energy storage cabinet, by means of bolts, fasteners, snap-fits, etc.

[0053] The water collection structure 2 is used to collect water flow, which may include condensate generated by the air conditioner in the energy storage cabinet during normal use, condensate overflowing from the cooling pipes in the battery compartment during maintenance, or wastewater from cleaning the inside of the energy storage cabinet during maintenance.

[0054] The water collection structure 2 has a drain outlet 2110 so that the water inlet section 11 of the drain pipe 1 can be connected to the interior of the water collection structure 2 through the drain outlet 2110, so that the water flow in the water collection structure 2 can be discharged from the drain outlet 2110 through the drain pipe 1 to the outside of the energy storage system.

[0055] Drainage outlet 2110 can be opened on the bottom wall of the water collection structure 2, or on the circumferential side wall of the water collection structure 2.

[0056] The axial position of the water outlet section 13 is available Figure 2 The letter 'c' in the text indicates that the axial position of the inlet section 11 can be determined using... Figure 2 The letter j in the text represents...

[0057] The drainage device may include a water collection structure 2 and a drain pipe 1. The water collection structure 2 can collect water flow in the energy storage system. Since the inlet section 11 of the drain pipe 1 is connected to the drain outlet 2110 of the water collection structure 2, the water flow in the water collection structure 2 enters the inlet section 11 through the drain outlet 2110. Since the inner wall of the highest point of the lifting section 12 is higher than the inner wall of the highest point of the inlet section 11, the water flow in the inlet section 11 forms a negative pressure at the lifting section 12 when it flows through the lifting section 12, generating a siphon effect. The axial position of the outlet section 13 is lower than the axial position of the inlet section 11. In other words, the outlet section 13 is lower than the inlet section 11. The lower outlet section 13 accelerates the water flow and maintains the siphon effect. This not only quickly discharges the water flow in the water collection structure 2, but also uses the negative pressure to generate a certain cleaning effect on the water collection structure 2, thereby improving the discharge efficiency of the water flow in the water collection structure 2.

[0058] Figure 3 This is a schematic diagram of the structure of a drainage pipe according to some embodiments of this application.

[0059] In some embodiments, combined with Figure 3 As shown, the distance between the highest point of the inner bottom wall of the lifting section 12 and the axis of the water inlet section 11 is greater than or equal to the inner diameter of the water inlet section 11.

[0060] In at least one embodiment, the distance between the highest point of the inner bottom wall of the lifting section 12 and the axis (represented by the letter j) of the water inlet section 11 can be represented by the letter h1, where h1 is greater than or equal to the inner diameter of the water inlet section 11.

[0061] The axis of the outlet section 13 (represented by the letter c) is higher than the axis of the inlet section 11 (represented by the letter j). In other words, the distance between the axis of the outlet section 13 and the axis of the inlet section 11 can be represented by the letter h2, and h2 is greater than zero.

[0062] Since the distance (h1) between the highest point of the inner bottom wall of the lifting section 12 and the axis of the inlet section 11 is greater than or equal to the inner diameter of the inlet section 11, the negative pressure at the lifting section 12 can be effectively increased. Meanwhile, the distance (h2) between the axis of the outlet section 13 and the axis of the inlet section 11 is greater than zero, which can maintain the siphon effect and ensure the siphon effect accordingly.

[0063] The larger h2 is, the better the siphon effect, which correspondingly increases the water inlet speed of the water collection structure 2 entering the water inlet section 11 through the drain outlet 2110.

[0064] Figure 4 This is a schematic diagram of the structure of the water collection tank and water collection part according to some embodiments of this application.

[0065] In some embodiments, combined with Figure 4 As shown, the water collection structure 2 includes a water collection tank 21, and the end of the water collection tank 21 along the first direction is provided with the drain outlet 2110. The bottom wall of the water collection tank 21 slopes down towards the drain outlet 2110 along the water flow direction.

[0066] In at least one embodiment, the water collection tank 21 may be a shell structure with an opening at the top and a hollow interior.

[0067] A drain outlet 2110 can be opened at one end of the water collection tank 21 along the first direction; the first direction refers to the length direction of the entire water collection tank 21, which can be connected with... Figure 4 The X-axis is parallel in the coordinate system.

[0068] The bottom wall of the water collection trough 21 slopes downwards towards the drain outlet 2110 along the water flow direction. This means that the end of the bottom wall of the water collection trough 21 near the drain outlet 2110 is lower than the end of the bottom wall of the water collection trough 21 away from the drain outlet 2110. In other words, the bottom wall of the water collection trough 21 slopes downwards relative to the drain outlet 2110. Figure 4 The water collection tank 21 is inclined to the horizontal plane formed by the XY axis. In other words, the bottom wall of the water collection tank 21 is inclined, so that the water in the water collection tank 21 can flow along the inclined bottom wall of the water collection tank 21 to the drain outlet 2110, so as to ensure that the water in the water collection tank 21 is completely drained.

[0069] Figure 5 for Figure 4 Enlarged view of section B.

[0070] In some embodiments, combined with Figure 5 As shown, the water collection structure 2 also includes a water collection part 22, which is fixed inside the water collection tank 21. The cross-sectional area of ​​the water collection part 22 gradually decreases along the water flow direction and is connected to and connected to the drain outlet 2110.

[0071] In at least one embodiment, the water collection part 22 can be fixedly installed on the inner bottom wall of the water collection tank 21 by means of adhesive, snap-fit, bolt fasteners, etc.

[0072] The cross-sectional area of ​​the water-gathering part 22 gradually decreases along the water flow direction. This means that the size of the end of the water-gathering part 22 away from the drain outlet 2110 is larger than the size of the end of the water-gathering part 22 near the drain outlet 2110. In other words, the area from the end of the water-gathering part 22 away from the drain outlet 2110 to the end of the water-gathering part 22 near the drain outlet 2110 becomes smaller. Since the water-gathering part 22 is connected to the drain outlet 2110, the relatively dispersed water flow in the water collection tank 21 can be guided and gathered by the water-gathering part 22 and flowed to the drain outlet 2110. This correspondingly accelerates the water flow in the water collection tank 21 to the water inlet section 11 of the drain pipe 1, thereby increasing the discharge speed of the water flow in the water collection tank 21.

[0073] Figure 6 This is a partial structural schematic diagram of a water collection structure according to some embodiments of this application.

[0074] In some embodiments, combined with Figure 5 and Figure 6 As shown, the water collection section 22 can adopt the following structure: the water collection section 22 includes at least one water collection plate 221, the water collection plate 221 is connected to the side wall of the water collection tank 21 and converges toward the drain outlet 2110.

[0075] In at least one embodiment, combined Figure 5 As shown, the water collecting section 22 may include two water collecting plates 221, for example, the two water collecting plates 221 are arranged at an included angle and are located on opposite sides of the drain outlet 2110. The drain outlet 2110 may be located in the middle region of the end of the water collecting trough 21 along the first direction. One end of each water collecting plate 221 is connected to the side wall of the water collecting trough 21 with the drain outlet 2110, and the other ends of the two water collecting plates 221 are correspondingly connected to the two side walls of the water collecting trough 21 along the second direction. The two water collecting plates 221 and the water collecting trough 21 with the drain outlet 2110 The sidewalls can be enclosed to form an isosceles trapezoidal shape, such that the size of the end regions of the two water-collecting plates 221 near the drain outlet 2110 is smaller than the size of the end regions of the two water-collecting plates 221 away from the drain outlet 2110; wherein, the water-collecting plates 221 are connected to the sidewalls of the water collection tank 21 and converge toward the drain outlet 2110, which can be understood as the size of the end regions of the two water-collecting plates 221 away from the drain outlet 2110 becoming smaller than the size of the end regions of the two water-collecting plates 221 near the drain outlet 2110.

[0076] Combination Figure 6As shown, the water collection part 22 may include a water collection plate 221. For example, a water collection plate 221 is set at an angle to the side wall of the water collection tank 21 along the first direction. The drain outlet 2110 may be located at the edge of the end of the water collection tank 21 along the first direction. One end of the water collection plate 221 is connected to the side wall of the water collection tank 21 with the drain outlet 2110, and the other end of the water collection plate 221 is connected to one side wall of the water collection tank 21 along the second direction. The water collection plate 221, the side wall of the water collection tank 21 with the drain outlet 2110, and the side wall of the water collection tank 21 along the second direction can be enclosed to form a shape similar to a right trapezoid.

[0077] The second direction refers to the width direction of the water collection tank 21, which can be connected with... Figure 5 and Figure 6 In the coordinate system, the Y-axis is parallel.

[0078] The two opposite ends of the water collecting plate 221 can be fixedly connected to the side wall of the water collecting trough 21 along the second direction and the side wall of the water collecting trough 21 with the drain outlet 2110 by means of bonding, welding or other methods.

[0079] Since the two opposite ends of the water-gathering plate 221 are respectively connected to the side wall of the water collection tank 21 along the second direction and the side wall of the water collection tank 21 with the drain outlet 2110, not only can the fixed connection between the water-gathering plate 221 and the water collection tank 21 be realized, but the water-gathering plate 221 and the side wall of the water collection tank 21 with the drain outlet 2110 can guide and gather the relatively dispersed water flow in the water collection tank 21, thereby improving the drainage effect of the water flow in the water collection tank 21.

[0080] Figure 7 This is one of the exploded structural diagrams of a drainage device according to some embodiments of this application.

[0081] In some embodiments, combined with Figure 7 As shown, the water collection structure 2 also includes a water collection part 23, which is fixed to the top of the water collection tank 21;

[0082] The water collection part 23 is provided with an opening 231, and the opening 231 is connected to the water collection tank 21;

[0083] The end of the water collection section 23 along the second direction is higher than the edge of the opening 231, and a guide surface 232 is provided between the end of the water collection section 23 along the second direction and the edge of the opening 231.

[0084] In at least one embodiment, the water collection part 23 may be fixedly connected to the water collection tank 21 by means of welding, riveting, bonding, bolt fasteners, etc.

[0085] The water collection section 23 is provided with an opening 231 communicating with the water collection tank 21. A guide surface 232 is provided between the edge of the opening 231 and the end of the water collection section 23 along the second direction. The end of the guide surface 232 away from the opening 231 is higher than the end of the guide surface 232 near the opening 231. Therefore, the guide surface 232 is relative to... Figure 7 The plane formed by the X and Y axes in the coordinate system is an inclined plane.

[0086] Since the end position of the water collection part 23 along the second direction is higher than the edge position of the opening 231, the water collection part 23 can use the inclined guide surface 232 to quickly guide the water flow of the energy storage system and enter the water collection tank 21 through the opening 231, thereby reducing the water flow retention time at the bottom of the energy storage system, realizing the water flow convergence over a larger area, and thus improving drainage efficiency.

[0087] In some embodiments, combined with Figure 7 As shown, the water collection structure 2 also includes a water leakage plate 24, which is located on the top of the water collection tank 21 and has water leakage holes 241.

[0088] In at least one embodiment, the drain plate 24 is provided with a plurality of drain holes 241 in an array; by opening a plurality of drain holes 241 on the drain plate 24, it can be ensured that when the water flow is large, the plurality of drain holes 241 will divide the water flow into small streams, so as to ensure the water leakage effect.

[0089] Each drain hole 241 can be polygonal, such as a hexagonal drain hole, so that the hexagonal drain hole can better disrupt the surface tension of the water flow, thereby reducing the large-area accumulation of water droplets on the drain plate 24.

[0090] Since the drain plate 24 is located at the top of the water collection tank 21, the water flowing through the drain hole 241 of the drain plate 24 can enter the water collection tank 21 under the influence of gravity.

[0091] Figure 8 for Figure 7 Enlarged view of section C.

[0092] In some embodiments, combined with Figure 7 and Figure 8 As shown, the water collection tank 21 includes a water collection tank body 211 and a support part 212. The top of the water collection tank body 211 is connected to the support part 212, and the water leakage plate 24 can be detachably installed through the support part 212.

[0093] In at least one embodiment, the end of the water collection tank body 211 along a third direction (e.g., the top of the water collection tank body 211) is connected to the support portion 212, so that the water collection tank body 211 and the support portion 212 form an integral structure of the water collection tank 21.

[0094] The third direction refers to the height direction of the water collection tank 21, which can be compared with... Figure 7 and Figure 8 In the coordinate system, the Z-axis is parallel.

[0095] The water collection tank body 211 can be connected to the support portion 212 in the following manner: for example, the water collection tank body 211 is bent and extended along a third-direction end, such as the top, toward the central region of the water collection tank 21 to form the support portion 212, which can be connected to... Figure 7 Since the planes formed by the X and Y axes in the coordinate system are parallel, the water collection tank body 211 and the support part 212 constitute an integrated water collection tank 21. Alternatively, the support part 212 and the top of the water collection tank body 211 can be connected and fixed by welding, bolt fasteners, or other methods.

[0096] A support portion 212 can be provided at the top end of the water collection tank body 211 along the first direction (see...). Figure 7 and Figure 8 (as shown), or, a support portion 212 may be provided at the top end of the water collection tank body 211 along the second direction, or, a support portion 212 may be provided at the top end of the water collection tank body 211 along both the first and second directions.

[0097] The two ends of the drain plate 24 can be detachably connected to the corresponding support part 212 by means of bolt fasteners, snap-fit, etc., so that the support part 212 not only provides vertical support for the drain plate 24, but also allows the drain plate 24 to be connected to the support part 212 in a detachable manner, which helps with the cleaning and maintenance of the drain plate 24.

[0098] In some embodiments, combined with Figure 8 As shown, the top of the water-collecting part 22 passes through the support part 212 and is attached to the bottom of the water-draining plate 24.

[0099] In at least one embodiment, the end of the water-collecting part 22 along a third direction, such as the top end, passes through (or penetrates) the support part 212, so that the top end of the water-collecting part 22 is flush with the top surface of the support part 212 and fits against the bottom of the drain plate 24, which can provide a certain support for the drain plate 24 and reduce the possibility of the drain plate 24 tilting.

[0101] In some embodiments, combined with Figure 9 and Figure 10As shown, the water collection structure 2 also includes a drain plate 24, which is disposed on the top of the water collection tank 21;

[0102] The area of ​​the water-draining plate 24 corresponding to the water-gathering part 22 is sealed to the edge of the opening 231. The area of ​​the water-draining plate 24 away from the water-gathering part 22 is provided with a notch 242, and the notch 242 is connected to the water collection tank 21.

[0103] In at least one embodiment, the area of ​​the drain plate 24 corresponding to the water collection part 22 can be defined as a wider area of ​​the drain plate 24, and the area of ​​the drain plate 24 away from the water collection part 22 can be defined as a narrower area.

[0104] Since the water collecting part 22 is located in the water collecting tank 21 near the drain outlet 2110, the area corresponding to the water collecting part 22 of the water leaking plate 24 is sealed to the edge of the opening 231 of the water collecting part 23 to prevent water from flowing between the water leaking plate 24 and the water collecting part 22 (the wider area) and the opening 231 into the area between the water collecting part 22 and the inner wall of the water collecting tank 21, so as to ensure the dryness of the area between the water collecting part 22 and the inner wall of the water collecting tank 21.

[0105] The drain plate 24 has a notch 242 at its end along the second direction in the narrower region away from the water collection section 22. If the water flow in the energy storage system is small and falls directly onto the water collection section 23, the water can flow into the water collection tank 21 through the guide surface 232 and the notch 242 of the water collection section 23. If the water flow in the energy storage system is large, the water can flow towards the drain plate 24 through the guide surface 232 of the water collection section 23. At this time, part of the water flows into the water collection tank 21 through the notch 242, and the other part flows into the water collection tank 21 through the drain hole 241 of the drain plate 24, thereby correspondingly improving the flow efficiency of the water collection section 23 in guiding the water to the water collection tank 21. The size of the notch 242 along the second direction can be 1-10 mm.

[0106] One or more embodiments of this application also disclose an energy storage system. The energy storage system includes the drainage device described in the above embodiments.

[0107] In at least one embodiment, the energy storage system further includes a cabinet, an air conditioner, a battery pack, etc. The air conditioner and battery pack can be fixedly installed inside the cabinet, and the air conditioner is used to cool the battery pack; the air conditioner can be a liquid-cooled air conditioner or an air-cooled air conditioner. The water collection structure 2 of the drainage device can be fixedly installed at the bottom of the cabinet.

[0108] Energy storage systems can be energy storage containers or energy storage cabinets. Battery compartments can be part of an energy storage system.

[0109] The drainage device can employ the following drainage process: During normal use, the air conditioner in the energy storage cabinet will generate at least one type of water flow, such as condensate, condensate overflowing from the cooling pipes in the battery compartment during maintenance, and wastewater from cleaning the interior during maintenance. This water flow falls or moves to the water collection section 23, and then quickly moves to the water collection tank 21 via the guide surface 232 of the water collection section 23. Smaller or non-flowing streams of water fall into the water collection tank between the guide surface 232 of the water collection section 23 and the notch 242 of the drain plate 24. Inside the tank 21, the water falling into the water collection tank 21 is accelerated by inertia by the inclined bottom wall of the water collection tank 21, and after being gathered by the water collection part 22, it flows to the drain outlet 2110 and enters the drain pipe 1 from the drain outlet 2110. When the water inlet section 11 of the drain pipe 1 is full of water, the water that continues to enter will start the siphon effect of the drain pipe 1 at the lifting section 12. The negative pressure generated by the siphon effect accelerates the speed at the water inlet section 11, and the drainage speed will become faster and faster. The fast water flow will also have a cleaning effect on the water collection tank 21.

[0110] The energy storage system of this embodiment has the same beneficial effects on related technologies as the drainage device described above, and will not be repeated here.

[0111] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
