Description

Technical Field

[0001] This invention relates to the field of energy storage unit testing equipment technology, and in particular to a rain test device for energy storage units. Background Technology

[0002] Energy storage units typically refer to devices or systems capable of storing electrical energy. They can store energy when electricity demand is low and release it when demand is high, thereby balancing the supply and demand of the power grid and improving its stability and reliability. Energy storage units can include various technologies, such as battery energy storage systems, pumped hydro storage, compressed air energy storage, and flywheel energy storage. Common energy storage units include energy storage cabinets and energy storage containers. When these energy storage units are actually put into use, their operating environment is usually outdoors, and they are inevitably affected by natural rainfall during long-term operation. Therefore, before actual use, they need to undergo rain testing using specialized equipment to ensure the quality of the energy storage units.

[0003] There are two main existing methods for rain testing. The simpler method involves the tester holding a water hose and continuously spraying water onto the outside of the energy storage unit to simulate natural rainfall. Although the simulation effect is poor, it can be used for rain testing of large energy storage containers. Smaller energy storage cabinets can be tested using a dedicated rain test chamber or rain test room. This method allows for continuous spraying of the energy storage unit through spray pipes surrounding the unit, and the spray position can be changed to better simulate rainfall conditions in nature.

[0004] However, existing rain test chambers still have certain shortcomings in actual use. First, energy storage units are located outdoors in actual use, and during rainy weather, they are not only affected by rainwater. If the area where they are placed is low-lying, there will also be water accumulation problems. However, existing rain test chambers do not have corresponding water accumulation testing mechanisms, and the test results are not comprehensive enough. Therefore, this invention provides a rain test device for energy storage units to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a rain test device for energy storage units. By setting up a closed plate and a test platform, the rain test effect in the prior art is not comprehensive enough.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

A water collection chamber is located below the test chamber. A test platform is installed in the test chamber. A sealing plate is fitted onto the test platform via a rotating rod. A servo motor for driving the test platform to rotate is fixedly installed at the bottom of the rain test chamber. A locking assembly is used to fix the relative position between the sealing plate and the test platform. The locking assembly is respectively disposed on the inner wall of the test platform and the outer side of the sealing plate. A sealing assembly is used to seal the connection between the sealing plate and the test platform after fixation. The sealing assembly is respectively disposed on the inner wall of the test platform and the outer side of the sealing plate.

[0008] Optionally, the test platform has a storage slot that matches the shape of the closed plate, and the test platform has evenly distributed arc-shaped slots.

[0009] Optionally, the test chamber has a first annular groove and a second annular groove corresponding to the position of the test platform. The first annular groove and the second annular groove have uniformly distributed seepage ports that communicate with the water accumulation chamber. The drive shaft of the servo motor passes through the middle of the water accumulation chamber and is fixedly connected to the bottom of the test platform.

[0010] Optionally, the bottom of the test platform is fitted with evenly distributed movable wheels, the installation position of the movable wheels corresponds to the opening position of the second annular groove, an opening is provided on one side of the test platform, and a fan-shaped plate is connected to the opening of the test platform, the shape of the fan-shaped plate being adapted to the shape of the first annular groove.

[0011] Optionally, the locking assembly includes a fixing rod movably sleeved inside the sealing plate and fixing holes formed on the inner wall of the test platform. The fixing holes are adapted to the shape of the end of the fixing rod, and the fixing holes are evenly distributed in a fan shape on the inner wall of the test platform.

[0012] Optionally, the closed plate has two sets of symmetrical accessory slots, and the fixed rod is externally connected to a transmission plate that is sleeved inside the accessory slot and fits against the inner side wall of the accessory slot. A spring piece located on one side of the transmission plate is fixedly connected to the accessory slot.

[0013] Optionally, the two ends of the spring are fixedly connected to the inner wall of the accessory groove through the connecting end, and a weakening groove is provided on the outside of the spring. The side of the spring facing the transmission plate is in contact with the transmission plate, and a support groove adapted to the outer surface shape of the fixed rod is provided on the side of the spring near the fixed rod. A through hole adapted to the size of the fixed rod is provided on the connecting end near the fixed rod.

[0014] Optionally, the closing plate has a buckle groove in the middle, a pull ring is fitted in the buckle groove, a transmission rod is movably connected to the accessory groove through a second rotating rod, the end of the fixed rod extends to the top of the transmission rod and is fixedly connected to a connector, the two ends of the pull ring extend into the interior of the accessory groove and are below the rising transmission rod, and both the end of the pull ring and the connector are provided with a sleeve groove, two sets of locking blocks are symmetrically connected in the sleeve groove, and a sliding groove adapted to the shape of the locking block is provided on the outside of the transmission rod.

[0015] Optionally, the sealing assembly includes a second sealing strip connected to the outside of the fixing rod and a first sealing strip corresponding to the position of the fixing hole. The sealing plate has a movable groove adapted to the shape of the second sealing strip. Two sets of symmetrically distributed sealing edges are fixedly connected to the side of the second sealing strip facing the first sealing strip. The shape of the first sealing strip is adapted to the shape of the sealing edge, and the sealing edge has a hollow structure.

[0016] Optionally, a plug strip is fixedly connected to the side of the second sealing strip facing the movable groove, a positioning block is fixedly connected to the plug strip, and a sleeve interface adapted to the shape of the second sealing strip, the plug strip, and the sealing edge is provided on the fixing rod, and a positioning groove adapted to the shape of the positioning block is provided on the fixing rod.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up a test platform and a sealing plate, the sealing plate can close the opening of the test platform before the rain test, forming a pool with the test platform. This allows the water sprayed during the operation of the sprinkler system to be stored and accumulated in the pool, simulating the water accumulation situation in the natural environment while conducting the rain test on the energy storage unit, thus improving the test effect of the equipment.

[0019] By setting a locking component, the sealing plate has a certain deflection range inside the test platform. During the process of adjusting the deflection of the sealing plate, the locking component can fix the sealing plate at different positions, so that the pool formed by the sealing plate and the test platform has multiple shapes, which can store water at different heights and simulate rain tests at different water heights, thereby further improving the test effect of the equipment.

[0020] By incorporating a pull ring, transmission rod, and spring in the locking assembly, the deflection adjustment of the sealing plate can be achieved simply by pulling the pull ring with one hand. After releasing the pull ring, the fixing rod automatically resets and aligns with the fixing hole, securing the sealing plate stably. This makes the deflection adjustment and fixing of the sealing plate simple, convenient, and highly stable.

[0021] By setting up a sealing component, during the adjustment of the sealing plate position, the fixing rod, in conjunction with the fixing hole, fixes the relative position of the sealing plate and the test platform, while also driving the second sealing strip to engage with the first sealing strip. This seals the gap between the sealing plate and the inner wall of the test platform, ensuring the water storage performance of the pool formed by the sealing plate and the test platform, providing a good environment for the equipment's water accumulation simulation test. At the same time, combining the sealing component with the locking component improves the correlation between the equipment structures.

[0022] By incorporating a sealing edge and positioning block in the sealing assembly, the second sealing strip and sealing edge can be quickly disassembled and replaced after long-term use and aging. Furthermore, when water accumulates in the sealing plate and test platform, the water pressure can be used to squeeze the hollow structure of the sealing edge, further improving the sealing effect of the sealing assembly. In addition, the interlocking state between the second sealing strip and sealing edge and the first sealing strip in the sealing assembly can also assist the insertion and fixing effect between the fixing rod and the fixing hole to a certain extent, further improving the stability of the sealing plate after fixing.

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0039] The following is a detailed description of a rain testing device for energy storage units provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0040] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0041] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0042] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0043] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0044] like Figures 1 to 12 As shown, an embodiment of the present invention provides a rain test device for an energy storage unit, including a rain test chamber 1, a door 2 on the outside of the rain test chamber 1, and a test chamber inside the rain test chamber 1. A spray system 3 is installed inside the test chamber. The spray system 3 can spray the test chamber to simulate rainfall after being started. The principle and installation method of the spray system 3 are the same as those of the prior art, and will not be described in detail here. A water accumulation chamber 9 is provided in the rain test chamber 1 located below the test chamber. A test platform 5 is installed in the test chamber. A sealing plate 6 is sleeved in the test platform 5 through a first rotating rod 19. A servo motor 4 for driving the test platform 5 to rotate is fixedly installed at the bottom of the rain test chamber 1. A locking component is used to fix the relative position between the sealing plate 6 and the test platform 5. The locking component is respectively set on the inner wall of the test platform 5 and the outside of the sealing plate 6. A sealing component is used to seal the sealing plate 6 and the test platform 5 after they are fixed. The sealing component is respectively set on the inner wall of the test platform 5 and the outside of the sealing plate 6. The test platform 5 has a storage slot 15 that matches the shape of the closed plate 6, and evenly distributed arc-shaped slots 12. A guide surface 21 is provided at one end of the test platform 5 near the storage slot 15. The height of the test platform 5 is the same as the height of the closed plate 6. The closed plate 6 can deflect around the first rotating rod 19 at the opening of the test platform 5, forming a pool structure capable of accumulating water. The evenly distributed arc-shaped slots 12 in the test platform 5 create recesses corresponding to the positions of the energy storage unit's moving wheels, thus allowing the energy storage unit to be properly positioned when moved to the test location. The movable wheels are used for storage, which helps to fix the energy storage unit during the test. The deflection of the sealing plate 6 at the opening of the test platform 5 can adjust the distance between the top of the sealing plate 6 and the top of the test platform 5, thereby changing the water height that can be stored in the pool to meet the needs of different depths of water accumulation simulation. When the sealing plate 6 is deflected to be completely stored in the storage tank 15, it can fill the storage tank 15. At the same time, its top end connects with the guide surface 21, so that the sealing plate 6 and the test platform 5 form an inclined plane under the action of the guide surface 21, which facilitates the passage of the energy storage unit through the storage tank 15 and makes it easy to move the energy storage unit.

[0045] In this embodiment, as Figures 3 to 6 As shown, the test chamber has a first annular groove 7 and a second annular groove 8 corresponding to the position of the test platform 5. The first annular groove 7 and the second annular groove 8 have evenly distributed seepage ports 10 that are connected to the water collection chamber 9. The drive shaft of the servo motor 4 passes through the middle of the water collection chamber 9 and is fixedly connected to the bottom of the test platform 5. The first annular groove 7 provides space for the installation of the test platform 5. The test platform 5 is fitted into the first annular groove 7. When the test platform 5 rotates, the movable wheel 11 engages with the inner side of the second annular groove 8 and moves along the trajectory formed by the second annular groove 8. The movable wheel 11 assists in limiting the test platform 5. Water after the rain test can leak into the water collection chamber 9 through the seepage ports 10 on the first annular groove 7 and the second annular groove 8 for storage and subsequent recycling. The bottom of the test platform 5 is fitted with evenly distributed movable wheels 11. The installation positions of the movable wheels 11 correspond to the opening positions of the second annular groove 8. An opening is provided on one side of the test platform 5, and a fan-shaped plate is connected to the opening of the test platform 5. The shape of the fan-shaped plate is adapted to the shape of the first annular groove 7. The test platform 5 can rotate under the drive of the servo motor 4. However, there is only one connection support point between the drive shaft of the servo motor 4 and the test platform 5. If the test platform 5 is completely supported by the bottom of the test cavity, it will cause the test platform 5 to rotate. The frictional resistance is relatively large during the process, which increases the workload of the servo motor 4. The movable wheel 11 is set to create a certain gap between the bottom of the test platform 5 and the first annular groove 7 and the second annular groove 8, which reduces the resistance during the rotation of the test platform 5. At the same time, it provides four support points for the bottom of the test platform 5 to maintain the stability of the test platform 5 during rotation. The fan-shaped plate at the opening of the test platform 5 is used to fill the first annular groove 7 and the second annular groove 8 at the opening of the test platform 5, so that the bottom surface of the test platform 5 and the inner side of the test cavity are flush, which facilitates the movement of the energy storage unit after it enters the test cavity. The locking assembly includes a fixing rod 20 movably fitted inside the sealing plate 6 and fixing holes 16 formed on the inner wall of the test platform 5. The fixing holes 16 are adapted to the shape of the end of the fixing rod 20, and the fixing holes 16 are evenly distributed in a fan shape on the inner wall of the test platform 5. The locking and fixing of the sealing plate 6 at different positions inside the test platform 5 is achieved by the fixing rod 20 and the fixing holes 16. After the sealing plate 6 is deflected to the position that needs to be fixed, the end of the fixing rod 20 can be inserted into the corresponding fixing hole 16 to fix the sealing plate 6. The fan-shaped distribution of the fixing holes 16 allows the sealing plate 6 to have multiple fixed states, forming a variety of different water accumulation simulations in conjunction with the test platform 5.

[0046] In this embodiment, as Figure 7 and Figure 8 as well as Figure 10As shown, the closed plate 6 has two symmetrical sets of accessory slots 23. The fixed rod 20 is fixedly connected to a transmission plate 26, which is sleeved inside the accessory slot 23 and fits against the inner wall of the accessory slot 23. A spring piece 25 located on one side of the transmission plate 26 is fixedly connected to the accessory slot 23. When the entire locking assembly is not subjected to external force, the spring piece 25 presses against the outside of the transmission plate 26 to squeeze and limit the transmission plate 26. The transmission plate 26 maintains the end of the fixed rod 20 protruding from both sides of the closed plate 6, so that the fixed rod 20 can be connected with the fixed hole 16 to fix the closed plate 6 stably. Both ends of the spring piece 25 are fixedly connected to the inner wall of the accessory groove 23 via the connecting end 34. A weakening groove 35 is provided on the outside of the spring piece 25. The side of the spring piece 25 facing the transmission plate 26 is in contact with the transmission plate 26. A support groove 36, matching the shape of the outer surface of the fixing rod 20, is provided on the side of the spring piece 25 near the fixing rod 20. A through hole 37, matching the size of the fixing rod 20, is provided on the connecting end 34 near the fixing rod 20. The spring piece 25 is in a mirror-image S-shaped structure. The weakening groove 35 is located in the middle region of the S-shaped structure, thus strengthening the spring piece 25 at that location. The weakening treatment of the structure makes the thickness at this point thinner, allowing the spring piece 25 to deform and generate elastic force when compressed. Thus, after the external force is removed, the spring piece 25 maintains the position of the transmission plate 26 and the fixed rod 20 through its own elastic force. The support groove 36 on the spring piece 25 is in contact with and fits against the outer surface of the fixed rod 20. At the same time, the spring piece 25 completely wraps around the fixed rod 20 through the hole 37, so that the spring piece 25 can play an auxiliary support and limit role for the fixed rod 20, preventing the fixed rod 20 from being misaligned during the movement, and further improving the stability of the fixed rod 20 during the movement.A latching groove 13 is provided in the middle of the sealing plate 6, and a pull ring 14 is fitted in the latching groove 13. A transmission rod 24 is movably connected to the accessory groove 23 via a second rotating rod 30. The end of the fixing rod 20 extends above the transmission rod 24 and is fixedly connected to a connector 27. Both ends of the pull ring 14 extend into the accessory groove 23 and are located below the rising transmission rod 24. A sleeve groove 28 is provided at the end of the pull ring 14 and on the connector 27. Two sets of locking blocks 29 are symmetrically connected in the sleeve groove 28. A sliding groove 31 that matches the shape of the locking block 29 is provided on the outside of the transmission rod 24. The pull ring 14 can move inside the latching groove 13. When the operator needs to deflect the sealing plate 6, he / she simultaneously pulls the pull ring 14 inside the latching groove 13 towards the top of the sealing plate 6, which will allow the contact plate to be turned. While locking the closing plate 6, the closing plate 6 is deflected. The operation can be completed with one hand. After the pull ring 14 moves upward, its end drives the bottom end of the transmission rod 24 to move to the outside and above the closing plate 6. Under the action of the second rotating rod 30, the transmission rod 24 is deflected. After the transmission rod 24 is deflected, its top end moves towards the lower center of the closing plate 6. At the same time, it pulls the connector 27 to move, causing the connector 27 to drive the fixed rod 20 to move towards the center of the closing plate 6. This retracts the end of the fixed rod 20 into the closing plate 6, thereby releasing the lock on the closing plate 6. During this process, the locking block 29 in the sleeve groove 28 always slides in the sliding groove 31 outside the transmission rod 24, ensuring the transmission connection between the end of the pull ring 14, the transmission rod 24, and the connector 27.

[0047] In this embodiment, as Figure 9 and Figure 11 as well as Figure 12As shown, the sealing assembly includes a second sealing strip 18 connected to the outside of the fixing rod 20 and a first sealing strip 17 corresponding to the positions of the fixing holes 16. The sealing plate 6 has a movable groove 22 that matches the shape of the second sealing strip 18. Two symmetrically distributed sealing edges 40 are fixedly connected to the side of the second sealing strip 18 facing the first sealing strip 17. The shape of the first sealing strip 17 matches the shape of the sealing edges 40, which are hollow. While locking the position of the sealing plate 6 after deflection adjustment, the fixing rod 20 can also move the second sealing strip 18 and connect it with the first sealing strip 17. The movable groove 22 in the sealing plate 6 can accommodate the second sealing strip 18, ensuring sufficient space for movement when the second sealing strip 18 moves with the fixing rod 20. There is a certain gap between the side of the sealing plate 6 and the test platform 5, allowing the sealing plate 6 to deflect inside the test platform 5. When the sealing plate 6 is locked under the action of the fixing rod 20, the outside of the fixing rod 20... The second sealing strip 18 of the part can mate with the first sealing strip 17 at the same position to seal the gap between the sealing plate 6 and the test platform 5, thereby enabling the pool formed by the test platform 5 and the sealing plate 6 to have a good water accumulation effect. The sealing edge 40 on the outer side of the second sealing strip 18 bends toward the middle of the second sealing strip 18, and both the second sealing strip 18 and the sealing edge 40 are made of rubber and have a certain elastic deformation capacity. Therefore, after contacting the first sealing strip 17, they can deform under the squeezing action driven by the fixing rod 20 and mate with the first sealing strip 17, so that the locking of the sealing plate 6 and the sealing between the test platform 5 and the sealing plate 6 are completed simultaneously. After water accumulates in the pool formed by the test platform 5 and the sealing plate 6, the pressure generated by the water can also squeeze the sealing edge 40 toward the inner side of the test platform 5, causing the hollow structure of the sealing edge 40 to deform and squeeze and adhere to the first sealing strip 17, thereby further improving the sealing effect after the second sealing strip 18, the first sealing strip 17, and the sealing edge 40 are combined. A connector strip 38 is fixedly connected to the side of the second sealing strip 18 facing the movable groove 22. A positioning block 39 is fixedly connected to the connector strip 38. The fixing rod 20 has a sleeve interface 32 that matches the shape of the second sealing strip 18, the connector strip 38, and the sealing edge 40. The fixing rod 20 also has a positioning groove 33 that matches the shape of the positioning block 39. After the second sealing strip 18 and the sealing edge 40 are aged and damaged after long-term use, they can be directly pulled out from the outside of the fixing rod 20 along with the connector strip 38. After replacing the second sealing strip 18, the second sealing strip 18, the connector strip 38, and the sealing edge 40 can be directly inserted through the sleeve interface 32 until the positioning block 39 on the connector strip 38 aligns with the positioning groove 33 on the fixing rod 20. This makes the disassembly and replacement of the second sealing strip 18, the connector strip 38, and the sealing edge 40 simple and convenient.

[0048] The working principle provided by this invention is as follows: When in use, open the door 2 to expose the space inside the rain test chamber 1, fasten the pull ring 14 and pull it. The pull ring 14 drives the fixing rod 20 to retract into the inner side of the sealing plate 6 through the transmission rod 24. The fixing rod 20 compresses the spring 25 through the transmission plate 26, causing the spring 25 to deform and simultaneously releasing the lock on the sealing plate 6. Then, push the sealing plate 6 as a whole into the inner side of the test platform 5 until the sealing plate 6 is completely embedded in the storage groove 15 and aligns with the guide surface 21 in the test platform 5. Release the pull ring 14, and the spring 25 resets under its own elastic force. The fixing rod 20 resets and inserts into the bottom fixing hole 16 to lock the sealing plate 6. Push the energy storage unit placed in the rain test chamber 1 onto the test platform 5. After passing over the sealing plate 6, the energy storage unit enters the inner side of the test platform 5 and is limited by the arc groove 12.

[0049] Adjust the position of the sealing plate 6 according to the required water depth, fasten the pull ring 14 again and pull to unlock the sealing plate 6. After rotating the sealing plate 6 around the first rotating rod 19 to an appropriate angle, release the pull ring 14. The fixing rod 20 resets and engages with the fixing hole 16 at the position to fix the sealing plate 6 stably. During the reset process of the fixing rod 20, the second sealing strip 18 is driven to connect with the first sealing strip 17, so that the two sides of the sealing plate 6 are sealed with the inner wall of the test platform 5. The test platform 5 and the sealing plate 6 cooperate to form a seal. Then close the box door 2 and wait for the rain test.

[0050] Start the rain test chamber 1. The spray system 3 in the rain test chamber 1 will work to spray the energy storage unit on the test platform 5. The servo motor 4 will work and drive the test platform 5 to rotate as a whole through its drive shaft. The deflection of the spray system 3 will ensure that the energy storage unit is sprayed from all sides. The water sprayed will accumulate in the test platform 5 to simulate the water accumulation situation of the energy storage unit. After the water level in the test platform 5 rises to be level with the top of the sealing plate 6, the excess water will be discharged from the sealing plate 6 and leak into the water accumulation chamber 9 through the seepage outlets 10 opened at the first annular groove 7 and the second annular groove 8, waiting for recycling. After the test is completed, open the chamber door 2 and insert the sealing plate 6 back into the storage groove 15 to release the water in the test platform 5.
