[0002] Energy storage units usually refer to devices or systems that can store electrical energy. They can store energy when electricity demand is low, and then release energy when electricity demand peaks, so as to balance the supply and demand of the power grid and improve the stability and reliability of the power grid. Energy storage units can include a variety of technical forms, such as battery energy storage systems, pumped storage, compressed air energy storage, flywheel energy storage, etc. Common energy storage units include energy storage cabinets and energy storage containers. When these energy storage units are actually put into use, their working environment is usually outdoors. In the long-term work, it is inevitable to be affected by natural rainfall. Therefore, before they are actually put into use, they need to be tested in the rain with special equipment to ensure the quality of the energy storage units.

[0003] There are two main existing rain test methods. The simpler method is for the tester to hold a water pipe and continuously spray water on the outside of the energy storage unit to simulate natural rainfall. Although the simulation effect is poor, it can be used for rain tests on larger energy storage containers, while smaller energy storage cabinets can be tested in a dedicated rain test box or rain test room. The energy storage unit can be continuously sprayed through a spray pipe surrounding the outside of the energy storage unit, and the spray position can be changed to better simulate the rainfall conditions in nature.

[0030] like Figures 1 to 12As shown, an embodiment of the present invention provides a rain test device for an energy storage unit, including a rain test box 1, a box door 2 is provided on the outside of the rain test box 1, and a test cavity is opened in the rain test box 1, and a spray system 3 is installed on the inside of the test cavity. The spray system 3 can spray simulated rainfall in the test cavity after startup. The principle and installation method of the spray system 3 are the same as those in the prior art, and will not be repeated here. A water accumulation chamber 9 is opened in the rain test box 1 and is located below the test cavity. A test platform 5 is installed in the test cavity, and a closing plate 6 is sleeved on the test platform 5 through a No. 1 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 box 1; a locking assembly, which is used to fix the relative position between the closing plate 6 and the test platform 5, and the locking assemblies are respectively arranged on the inner side wall of the test platform 5 and the outer side of the closing plate 6; a sealing assembly, which is used for sealing between the closing plate 6 and the test platform 5 after fixing, and the sealing assemblies are respectively arranged on the inner side wall of the test platform 5 and the outer side of the closing plate 6. The test platform 5 is provided with a receiving groove 15 which matches the shape of the closing plate 6, and the test platform 5 is provided with evenly distributed arc grooves 12. A guide surface 21 is provided at one end of the test platform 5 close to the receiving groove 15, and the height value of the test platform 5 is the same as the height value of the closing plate 6. The closing plate 6 can deflect around the first rotating rod 19 at the opening of the test platform 5, and cooperate with the test platform 5 to form a pool structure capable of generating water accumulation. The evenly distributed arc grooves 12 in the test platform 5 form a depression on the test platform 5 corresponding to the position of the moving wheel of the energy storage unit, so that when the energy storage unit moves to the test position, it is The moving wheels are used for storage and storage, thereby assisting in fixing the energy storage unit during the test process. The deflection of the closing plate 6 at the opening of the test platform 5 can adjust the distance between the top of the closing plate 6 and the top of the test platform 5, thereby changing the height of the accumulated water that can be stored in the pool body, so as to meet the simulation needs of water accumulation at different depths. When the closing plate 6 is deflected to be completely stored in the storage groove 15, the storage groove 15 can be filled, and at the same time, its top end is docked with the guide surface 21, so that an inclined surface is formed between the closing plate 6 and the test platform 5 under the action of the guide surface 21, which facilitates the passage of the energy storage unit from the storage groove 15 and makes it easy to move the energy storage unit.

[0031] In this embodiment, if Figures 3 to 6As shown, the test cavity is provided with a first annular groove 7 and a second annular groove 8 corresponding to the position of the test platform 5, and the first annular groove 7 and the second annular groove 8 are provided with uniformly distributed seepage ports 10 connected with the water accumulation chamber 9. The driving shaft of the servo motor 4 passes through the middle of the water accumulation chamber 9 and is fixedly connected with the bottom of the test platform 5. The first annular groove 7 provides space for the installation of the test platform 5, and the test platform 5 is sleeved on the first annular groove 7. When the test platform 5 rotates, the movable wheel 11 is clamped on the inner side of the second annular groove 8 and moves along the trajectory formed by the second annular groove 8, and the movable wheel 11 cooperates with the test platform 5 to assist in limiting the position. The water after the rain test can leak into the water accumulation chamber 9 through the seepage ports 10 provided on the first annular groove 7 and the second annular groove 8 for storage, and wait for subsequent recycling. The bottom of the test platform 5 is sleeved with evenly distributed movable wheels 11, and the installation position of the movable wheels 11 corresponds to the opening position of the second annular groove 8. An opening is set on one side of the test platform 5, and a fan-shaped flat plate is connected to the opening of the test platform 5. The shape of the fan-shaped flat plate is adapted to the shape of the first annular groove 7. At the bottom of the test platform 5, the test platform 5 can rotate under the drive of the servo motor 4, but there is only one connection support point between the drive shaft of the servo motor 4 and the test platform 5. If the support of the test platform 5 is completely dependent on the bottom of the test cavity, the test platform 5 will rotate. The friction resistance is relatively large during the process, which increases the workload of the servo motor 4. The movable wheel 11 is arranged 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, thereby reducing the resistance during the rotation of the test platform 5. At the same time, four support points are provided for the bottom of the test platform 5 to maintain the stability of the test platform 5 during rotation. The fan-shaped flat 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 test platform 5 is flush with the bottom surface of the inner side of the test cavity, which facilitates the movement of the energy storage unit after entering the test cavity. The locking assembly includes a fixing rod 20 movably mounted on the inner side of the closing plate 6 and a fixing hole 16 opened on the inner wall of the test platform 5. The fixing hole 16 is 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 closing plate 6 is fixed at different positions on the inner side of the test platform 5 by the fixing rod 20 and the fixing hole 16. After the closing plate 6 is deflected to the position where it needs to be fixed, the end of the fixing rod 20 can be inserted into the fixing hole 16 at the corresponding position to fix the closing plate 6. The fan-shaped distribution of the fixing holes 16 allows the closing plate 6 to have multiple fixed states, which cooperates with the test platform 5 to form water accumulation simulations in various different situations.

[0032] In this embodiment, if Figure 7 and Figure 8 as well as Fig.10As shown, two symmetrical groups of accessory grooves 23 are provided in the closing plate 6, and a transmission plate 26 which is sleeved on the inner side of the accessory groove 23 and fits with the inner side wall of the accessory groove 23 is fixedly connected to the outside of the fixing rod 20, and a spring piece 25 located on one side of the transmission plate 26 is fixedly connected to the fitting groove 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, and the transmission plate 26 is maintained to protrude from both sides of the closing plate 6 through the transmission plate 26, so that the fixing rod 20 can be docked with the fixing hole 16, and the closing plate 6 is fixed and stabilized. The two ends of the spring piece 25 are fixedly connected to the inner wall of the accessory groove 23 through the connecting end 34, and 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 fitted between the transmission plate 26, and the side of the spring piece 25 close to the fixed rod 20 is provided with a supporting groove 36 adapted to the outer surface shape of the fixed rod 20, and the connecting end 34 close to the fixed rod 20 is provided with a through hole 37 adapted to the size of the fixed rod 20. The spring piece 25 is in the shape of an S-shaped structure that is mirrored to each other. The weakening groove 35 is arranged in the middle area of ​​the S-shaped structure to achieve the connection of the spring piece 25 at this place. The weakening treatment of the structure makes the thickness of this place thinner, so that the spring sheet 25 can be deformed at this place after being squeezed and generate elastic force, so that the position state of the transmission plate 26 and the fixed rod 20 is maintained by its own elastic force after the external force is removed. The support groove 36 on the spring sheet 25 and the outer surface of the fixed rod 20 are in contact and fit with each other. At the same time, the hole 37 completely wraps the fixed rod 20, so that the spring sheet 25 can play a role of auxiliary support and limit the fixed rod 20, thereby avoiding the misalignment of the fixed rod 20 during the activity, and further improving the stability of the fixed rod 20 during the activity.A buckle groove 13 is provided in the middle of the closing plate 6, and a pull ring 14 is sleeved in the buckle groove 13. A transmission rod 24 is movably connected to the accessory groove 23 through a No. 2 rotating rod 30. The end of the fixing rod 20 extends to the top of the transmission rod 24 and is fixedly connected to a connecting head 27. Both ends of the pull ring 14 extend to the inside of the accessory groove 23 and are located below the rising transmission rod 24. A sleeve groove 28 is provided on the end of the pull ring 14 and the connecting head 27. Two groups of blocks 29 are symmetrically connected in the sleeve groove 28. A sliding groove 31 that matches the shape of the block 29 is provided on the outside of the transmission rod 24. The pull ring 14 can move on the inner side of the buckle groove 13. When the staff needs to deflect the closing plate 6, they can pull the pull ring 14 on the inner side of the buckle groove 13 toward the top of the closing plate 6 by hand at the same time, so that they can contact the closing plate 6. The closing plate 6 is locked and deflected at the same time, and 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 toward the upper outside of the closing plate 6, and makes the transmission rod 24 deflected under the action of the No. 2 rotating rod 30. After the transmission rod 24 is deflected, its top end moves toward the lower middle part of the closing plate 6, and at the same time pulls the connecting head 27 to move, so that the connecting head 27 drives the fixing rod 20 to move toward the middle of the closing plate 6, and retracts the end of the fixing rod 20 into the closing plate 6, thereby releasing the lock of the closing plate 6. During this process, the block 29 in the sleeve groove 28 always slides in the slide groove 31 outside the transmission rod 24, ensuring the transmission connection relationship between the end of the pull ring 14, the transmission rod 24, and the connecting head 27.

[0033] In this embodiment, if Fig. 9 and Fig.11 as well as Fig.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 position of the fixing hole 16. A movable groove 22 adapted to the shape of the second sealing strip 18 is provided in the closing plate 6. The second sealing strip 18 is fixedly connected to one side of the first sealing strip 17 with two sets of symmetrically distributed sealing edges 40. The shape of the first sealing strip 17 is adapted to the shape of the sealing edge 40. The sealing edge 40 is a hollow structure. While the fixing rod 20 locks the position of the closing plate 6 after deflection adjustment, it can also drive the second sealing strip 18 to move and dock with the first sealing strip 17. The movable groove 22 provided in the closing plate 6 can accommodate the second sealing strip 18 to ensure that the second sealing strip 18 has sufficient space for movement when moving with the fixing rod 20. There is a certain gap between the side of the closing plate 6 and the test platform 5, so that the closing plate 6 can deflect on the inner side of the test platform 5. When the closing plate 6 is locked under the action of the fixing rod 20, the outside of the fixing rod 20 The second sealing strip 18 at the bottom can dock with the first sealing strip 17 at this position to close the gap between the closing plate 6 and the test platform 5, so that the pool body formed by the test platform 5 and the closing plate 6 has a good water accumulation effect, and the sealing edge 40 on the outside of the second sealing strip 18 is bent toward the middle of the second sealing strip 18, and the second sealing strip 18 and the sealing edge 40 are both made of rubber and have a certain elastic deformation ability. Therefore, after contacting the first sealing strip 17, they can be deformed under the extrusion driven by the fixing rod 20 and produce a docking effect with the first sealing strip 17, so that the locking of the closing plate 6 and the sealing between the test platform 5 and the closing plate 6 are completed simultaneously. After the pool body formed by the test platform 5 and the closing plate 6 accumulates water, the pressure generated by the accumulated water can also squeeze the sealing edge 40 toward the inside of the test platform 5, so that the hollow structure of the sealing edge 40 is deformed, and the first sealing strip 17 is squeezed and fitted, thereby further improving the sealing effect of the second sealing strip 18, the first sealing strip 17, and the sealing edge 40 after cooperation. A plug-in strip 38 is fixedly connected to the side of the second sealing strip 18 facing the movable groove 22, and a positioning block 39 is fixedly connected to the plug-in strip 38. A socket interface 32 that matches the shape of the second sealing strip 18, the plug-in strip 38, and the sealing edge 40 is provided on the fixing rod 20, and a positioning groove 33 that matches the shape of the positioning block 39 is provided on the fixing rod 20. After the second sealing strip 18 and the sealing edge 40 are aged and damaged due to long-term use, they can be directly pulled out from the outside of the fixing rod 20 together with the plug-in strip 38. After replacing the new second sealing strip 18, the second sealing strip 18, the plug-in strip 38, and the sealing edge 40 can be directly inserted through the socket interface 32 until the positioning block 39 on the plug-in strip 38 is docked with the positioning groove 33 on the fixing rod 20, so that the disassembly and replacement operation of the second sealing strip 18, the plug-in strip 38, and the sealing edge 40 is simple and convenient.

[0034] The working principle provided by the present invention is that when in use, the box door 2 is opened to expose the space inside the rain test box 1, the pull ring 14 is buckled and pulled, and the pull ring 14 drives the fixing rod 20 to retract into the inner side of the closing plate 6 through the transmission of the transmission rod 24, and the fixing rod 20 compresses the spring piece 25 through the transmission plate 26 to deform the spring piece 25, and at the same time releases the lock of the closing plate 6, and then the closing plate 6 is pushed toward the inner side of the test platform 5 as a whole, until the closing plate 6 is completely embedded in the storage groove 15 and docked with the guide surface 21 in the test platform 5, the pull ring 14 is released, and the spring piece 25 is reset under the action of its own elastic force, and the fixing rod 20 is reset and inserted into the lowest fixing hole 16 to lock the closing plate 6, and the energy storage unit placed in the rain test box 1 is pushed onto the test platform 5, and the energy storage unit passes through the closing plate 6 and enters the inner side of the test platform 5, and is limited by the arc groove 12; Adjust the position of the closing plate 6 according to the depth of water accumulation to be tested, buckle the pull ring 14 again and pull it to unlock the closing plate 6, deflect the closing plate 6 around the No. 1 rotating rod 19 to an appropriate angle and then release the pull ring 14, reset the fixing rod 20 and engage with the fixing hole 16 at this position to fix the closing plate 6 stably, and during the reset process of the fixing rod 20, drive the second sealing strip 18 to dock with the first sealing strip 17, so that a seal is formed between the two sides of the closing plate 6 and the inner wall of the test platform 5, and the test platform 5 and the closing plate 6 cooperate to form, and then close the box door 2 and wait for the rain test; The rain test box 1 is started, and the spray system 3 in the rain test box 1 works to perform a spray test on the energy storage unit on the test platform 5. The servo motor 4 works and drives the test platform 5 to rotate as a whole through its drive shaft, and cooperates with the deflection of the spray system 3 to ensure the comprehensive spraying of the energy storage unit. The water under the spraying accumulates in the test platform 5, and the accumulated water is formed in the test platform 5 to simulate the water accumulation of the energy storage unit. After the accumulated water surface in the test platform 5 rises to be flush with the top of the closing plate 6, the excess water is discharged from the closing plate 6 and leaks into the water accumulation chamber 9 through the seepage port 10 opened at the first annular groove 7 and the second annular groove 8, waiting for recycling. After the test is completed, the box door 2 is opened, and the closing plate 6 is stuck in the storage groove 15 again to release the accumulated water in the test platform 5. Finally, the energy storage unit after the rain test is pushed out to complete the use process of the entire energy storage unit using the rain test equipment.
