Description

Technical Field

[0001] The present invention relates to the technical field related to switch testing, and in particular to a durability testing device and a testing method for a switch in a smart energy station. Background Art

[0002] As the core hub of modern energy management, smart energy stations integrate advanced technologies such as the Internet of Things, big data, and artificial intelligence to achieve real-time energy monitoring, optimized scheduling, and low-carbon management. Centrifugal refrigeration units, as one of the core components of smart energy stations, fulfill key functions in efficient refrigeration and energy management. These units consist of core components such as a centrifugal refrigeration compressor, evaporator, condenser, main motor, air recovery device, lubrication system, control cabinet, and starting cabinet. These units typically adopt a compact "assembly-type" design, highly integrating various components. These units are available in three types: fully enclosed, semi-enclosed, and open, to meet the energy needs of different scenarios.

[0003] The Smart Energy Station utilizes this highly efficient unit to achieve precise cooling output and energy allocation, ensuring stable and energy-efficient system operation. The various switchgear within the unit, serving as the key components for opening and closing, undergo rigorous durability testing before shipment due to their high-frequency use. This ensures the long-term, reliable operation of the Smart Energy Station and provides solid support for energy management.

[0004] Existing test equipment has significant shortcomings in terms of component layout and fastening mechanisms. First, the lack of flexible component layout prevents interference from overhead mechanisms when placing switch components, which can lead to inaccurate positioning of switch components and affect the final test results. Second, manual operation during switch component placement can lead to positioning deviations or improper fastening force, damaging switch components or introducing human errors. This also increases operational complexity, making it difficult for existing test equipment to meet the requirements of efficient and accurate switch durability testing, limiting the reliability of test results and the comprehensiveness of data.

[0010] As a further solution of the present invention: the rolling cooperation structure includes a connecting arm fixedly connecting the two cross bars and a roller mounted on the connecting arm, and a limiting plate cooperating with the roller is further fixed in the outer shell; In which, the limiting plate is provided with a first limiting surface and a second limiting surface connected to each other, the second limiting surface is parallel to the fixing member, and when the frame moves toward the outside or inside of the outer shell, the second limiting surface cooperates with the roller and can cause the third spring to rebound or compress.

[0011] As a further solution of the present invention: the boosting mechanism includes a guide plate fixed in the outer shell and having a hollow interior, and a connecting block slidably arranged in the guide plate and fixed to the side of the frame; A second screw rod is rotatably mounted in the guide plate, and the second screw rod passes through the connecting block and is threadedly connected to the connecting block.

This design not only simplifies the operational process but also improves the accuracy and reliability of the test. Specifically, when the frame is pulled back into the outer shell, the elastic drive mechanism drives the follower block and the clamping block to move toward the switch assembly, clamping it. When the frame is pushed out of the outer shell, the elastic drive mechanism releases, and the clamping block releases the switch assembly. The entire process requires no human intervention, greatly improving work efficiency while also reducing the risk of errors and damage that may be caused by improper human operation. In addition, by manipulating the rotation of the first screw rod, the distance between the second ring body and the first ring body can be adjusted, thereby changing the initial compression of the first spring, realizing the adjustment of the pressure exerted on the switch assembly, making the detection data more comprehensive, and providing an effective reference for the evaluation of switch durability.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] See also Figures 1-10 In an embodiment of the present invention, a smart energy station switch durability testing device includes an outer shell 1 and further includes: A frame 2, which can be driven into and out of the outer shell 1 by two sets of boosting mechanisms provided in the outer shell 1, and a plurality of fastening mechanisms for placing the switch assembly to be tested are provided on the frame 2 at equal intervals along its length, and the fastening mechanisms cooperate with two sets of elastic driving mechanisms provided on both sides of the frame 2; The pressing mechanism is provided in the outer shell 1 and located above the frame 2 . The pressing mechanism can perform a lifting action in the outer shell 1 to apply pressure to the switch assembly.

[0031] It should be noted that a control panel (not numbered in the figure) is located on the side of the outer shell 1. During operation, the operator can adjust various parameters during the test by manipulating the control panel. The system also includes a counting mechanism, an inrush current control unit, a load circuit, and a monitoring and protection unit. The counting mechanism records the number of presses, the inrush current control unit simulates the current surge scenarios that the switch may encounter in actual use, the load circuit simulates a variety of load types and operating conditions, and the monitoring and protection unit monitors parameters such as current and voltage during the test.

[0032] Furthermore, when performing the test operation, the staff first operates the boosting mechanism to allow the frame 2 to move smoothly from the inside of the outer shell 1 to the outside. After the frame 2 completely stops outside the outer shell 1, the switch assembly to be tested is gently placed on the designated position of the frame 2. Subsequently, the staff starts the boosting mechanism again, and the frame 2 begins to move slowly into the inside of the outer shell 1. In the process of the frame 2 gradually entering the outer shell 1, the fastening mechanism is triggered, and a precise clamping action is performed on the switch assembly to ensure that it remains stable during subsequent testing and will not be displaced during the press test due to unstable placement, thereby avoiding deviations in the test results. After completing the above preparations, start the pressing mechanism, which will intermittently apply pressure to the switch assembly according to a preset frequency and force to simulate the pressing conditions in actual use to test the durability and reliability of the switch assembly.

[0033] Please refer again Figure 3 、 Figure 7 as well as Figure 8 The fastening mechanism includes an empty box 16 fixed to the frame 2. The empty box 16 is provided with a placement position 1601 for the switch assembly. Two sets of elastic limiters are symmetrically arranged inside the empty box 16. When the frame 2 is moved from the outside to the inside of the outer shell 1, the elastic driving mechanism can drive the two sets of elastic limiters toward each other. The elastic limiters include a follower block 19 and a clamping block 20 that are slidably arranged in the empty box 16. A guide shaft 17 is also fixed to the empty box 16. The guide shaft 17 passes through the follower block 19 and the clamping block 20 and is slidably connected to them. Among them, a second spring 18 is connected between the follower block 19 and the clamping block 20, and the second spring 18 is sleeved on the outer periphery of the guide shaft 17. The clamping block 20 is provided with a clamping portion 2001 extending into the upper part of the empty box 16, and the follower block 19 is connected to a boss 1901 located outside the empty box 16 and cooperating with the elastic driving mechanism.

[0034] In detail, during the test operation, the staff manipulates the boost mechanism to allow the frame 2 to move smoothly from the outside to the inside of the outer shell 1. When the frame 2 enters the outer shell 1, the boss 1901 works in conjunction with the elastic drive mechanism to push the follower block 19 and the clamping block 20 to move synchronously toward the switch assembly, thereby achieving precise clamping of the switch assembly. The upper and lower parts of the empty box 16 are respectively provided with through grooves, which provide the necessary space for the movement of the connecting parts between the clamping part 2001 and the clamping block 20, and the connecting parts between the boss 1901 and the follower block 19. Specifically, the upper through groove allows the clamping part 2001 and the clamping block 20 to move smoothly, while the lower through groove ensures that the connecting parts between the boss 1901 and the follower block 19 can move unimpeded. Throughout the process, the movements of the various components are coordinated to ensure that the switch assembly is firmly clamped, avoiding displacement in subsequent tests, thereby ensuring the accuracy of the test results; Furthermore, the elastic driving mechanism acts on the follower block 19 through the boss 1901. When the clamping portion 2001 contacts the switch assembly, as the follower block 19 continues to move, the clamping portion 2001 and the clamping block 20 become stationary, and the distance between the follower block 19 and the clamping block 20 gradually shortens. The second spring 18 is compressed, thereby realizing a flexible clamping function for the switch assembly, avoiding damage to the switch assembly caused by rigid clamping that is difficult to control the clamping force.

[0035] Please refer again Figure 6 and Figure 9The elastic driving mechanism includes a fixing part 21 fixed to the bottom of the frame 2 and two cross bars 22 slidably provided on the fixing part 21 and axially consistent with the length direction of the frame 2. The two cross bars 22 are respectively fixedly connected to a transmission plate 24, and the transmission plate 24 is provided with a plurality of inclined grooves 2401 adapted to the bosses 1901. The bosses 1901 extend into the inclined grooves 2401 and are slidably connected to the transmission plate 24; the inclined grooves 2401 on the two transmission plates 24 are symmetrically arranged, and a round table 2201 is also fixed to the end of the cross bar 22. A third spring 23 sleeved on the outer circumference of the cross bar 22 is connected between the round table 2201 and the fixing part 21, and the two cross bars 22 are also connected to a rolling matching structure. The rolling engagement structure includes a connecting arm 25 fixedly connecting the two crossbars 22 and a roller 26 mounted on the connecting arm 25. A limiting plate 27 is also fixed within the outer shell 1 and engages with the roller 26. The limiting plate 27 is provided with a first limiting surface 2701 and a second limiting surface 2702 connected to each other. The second limiting surface 2702 is parallel to the fixing member 21. When the frame 2 moves toward the outside or inside of the outer shell 1, the second limiting surface 2701 engages with the roller 26 and can cause the third spring 23 to rebound or compress.

[0036] Specifically, with Figure 6 Taking the state shown as an example, at this time, the frame body 2 is located in the outer shell 1, the roller 26 is in contact with the second limiting surface 2702, the third spring 23 is in a compressed state, and the switch assembly located at the placement position 1601 is fastened by the clamping parts 2001 on both sides; When the staff controls the boosting mechanism to drive the frame 2 to move toward the outside of the outer shell 1, the roller 26 will roll along the second limiting surface 2702. After the roller 26 separates from the second limiting surface 2702, the third spring 23 will begin to rebound, and the roller 26 contacts the first limiting surface 2702. Accordingly, the cross bar 22 drives the transmission plate 24 to gradually slide toward the fixing member 21. The boss 1901 slides with the transmission plate 24 through the inclined groove 2401, so that the boss 1901 drives the follower block 19 to give way. Then, the follower block 19 will slide away from the placement position 1601 in the empty box 16 until the second spring 18 rebounds to a natural state, the clamping portion 2001 is separated from the switch assembly, and the fastening state of the switch assembly is released, so that the switch assembly can be removed from the placement position 1601 after the test is completed. On the contrary, before the test starts, after the switch assembly is placed on the placement position 1601, the booster mechanism drives the frame 2 to move toward the interior of the outer shell 1, and the roller 26 will contact the first limit surface 2701. As can be seen from the accompanying drawings, the first limit surface 2701 is tilted, so the roller 26 will drive the two cross bars 22 to give way through the connecting arm 25, and the cross bar 22 drives the transmission plate 24 to slide away from the fixing member 21. The third spring 23 is compressed, and the boss 1901 gives way under the action of the inclined groove 2401, so that the follower block 19 and the clamping block 20 move synchronously toward the switch assembly, thereby achieving precise clamping of the switch assembly and avoiding displacement of the switch assembly in subsequent tests, thereby ensuring the accuracy of the test results.

[0037] In summary, the present application arranges multiple empty boxes 16 at equal intervals on the frame 2, and each empty box 16 is provided with a placement position 1601, so that the empty box 16 is similar to a drawer that can be loaded with the switch assembly to be tested. When arranging the switch assembly, the staff can easily place the switch assembly in the specified position of the empty box 16 without worrying about the interference of the upper pressing mechanism, thereby effectively avoiding the problem of inaccurate positioning of the switch assembly. In addition, when the frame 2 enters and exits the outer shell 1, the elastic drive mechanism can be automatically triggered to switch the state of the fastening mechanism. This design not only simplifies the operating process, but also improves the accuracy and reliability of the test. Specifically, when the frame 2 is pushed out of the outer shell 1 by the booster mechanism, the elastic drive mechanism is automatically released, so that the fastening mechanism is in a loose state, which facilitates the staff to quickly replace or adjust the switch assembly; and when the frame 2 is pushed back into the outer shell 1, the elastic drive mechanism is triggered again, and the fastening mechanism automatically clamps the switch assembly to ensure its stability during the test. The entire process does not require human intervention, which greatly improves work efficiency and reduces the risk of errors and damage caused by improper human operation.

[0038] Please refer again Figure 7 The boost mechanism includes a guide plate 12 fixed in the outer shell 1 and hollow inside, and a connecting block 14 slidably arranged in the guide plate 12 and fixed to the side of the frame 2; a second screw rod 13 is also rotatably installed in the guide plate 12, and the second screw rod 13 passes through the connecting block 14 and is threadedly connected to the connecting block 14. A drive motor 15 with an output end connected to the second screw rod 13 is also installed in the outer shell 1.

[0039] In the device described herein, the drive motor 15 is a servo motor with bidirectional drive at its output end. During operation, the drive motor 15 can drive the second screw rod 13 to rotate in either the forward or reverse direction. Due to the threaded engagement between the second screw rod 13 and the connecting block 14, the connecting block 14, driven by the second screw rod 13, slides along the guide plate 12. Accordingly, the connecting block 14 drives the frame 2, guided by the guide plate 12, to move in and out of the outer housing 1.

[0040] Specifically, when the drive motor 15 rotates forward, the second screw rod 13 rotates forward accordingly, and the connecting block 14 slides outward along the guide plate 12, thereby driving the frame 2 to move out from the inside of the outer shell 1; conversely, when the drive motor 15 rotates reversely, the second screw rod 13 rotates reversely, the connecting block 14 slides inward along the guide plate 12, and the frame 2 is pulled back into the inside of the outer shell 1.

[0041] As the frame 2 moves in and out of the outer shell 1, the elastic drive mechanism automatically triggers, switching the state of the fastening mechanism. Specifically, when the frame 2 is pulled back into the outer shell 1, the elastic drive mechanism drives the follower block 19 and the clamping block 20 to move toward the switch assembly, clamping it. When the frame 2 is pushed out of the outer shell 1, the elastic drive mechanism releases, and the clamping block 20 releases the switch assembly.

[0042] Please refer again Figure 3 and Figure 10 Two columns 3 are fixed in the outer shell 1, and a lifting plate 4 is slidably provided on the two columns 3. The downward pressing mechanism includes a hydraulic cylinder 5 installed in the outer shell 1, and the movable end of the hydraulic cylinder 5 is fixed to the lifting plate 4; the lifting plate 4 is provided with multiple groups of adjustable pressure components along its own length direction corresponding to the position of the fastening mechanism.

[0043] It should be noted that, when the boosting mechanism drives the frame 2 into the interior of the outer shell 1, the multiple placement positions 1601 are respectively located below the multiple groups of adjustable pressure components. Then, the hydraulic cylinder 5 works and can drive the multiple groups of adjustable pressure components to move up and down through the lifting plate 4 to perform durability testing on the switch components located at the placement positions 1601.

[0044] The adjustable pressure assembly includes an assembly plate 6 fixed to the lifting plate 4, a vertical shaft 7 slidably mounted on the assembly plate 6, and a pressure head 8 detachably connected to the vertical shaft 7. A stop boss 701 is fixedly mounted on the end of the vertical shaft 7 away from the pressure head 8, which abuts against the assembly plate 6. A first spring 11 is also sleeved around the outer circumference of the vertical shaft 7. One end of the first spring 11 is connected to a first ring 702 fixed to the vertical shaft 7, and the other end is connected to a debugging structure mounted on the assembly plate 6.

[0045] It should be noted that, during long-term use of the test equipment, wear of the indenter 8 may affect the accuracy of the test results. To address this issue, the present application adopts a detachable connection design between the indenter 8 and the vertical shaft 7. Specifically, the indenter 8 is connected to the vertical shaft 7 via threads, snaps, or other quick connection methods, allowing personnel to easily remove and install the indenter 8 according to actual needs.

[0046] This design has many benefits. First, it makes it easy for staff to regularly inspect the pressure head 8. Through visual observation or the use of measuring tools, it is possible to accurately determine whether the pressure head 8 is worn and the extent of the wear. If it is found that the wear of the pressure head 8 has reached a certain extent, affecting the accuracy of the test, the staff can replace the new pressure head 8 in time to ensure the reliability of the test results. In addition, the design of the detachable connection also improves the flexibility and adaptability of the equipment. According to different test tasks and the characteristics of the switch component to be tested, the staff can choose pressure heads 8 of different materials, shapes and sizes for replacement to better match the specific test requirements and further improve the accuracy and efficiency of the test.

[0047] The debugging structure includes a first screw rod 9 rotatably mounted on the assembly plate 6 and a threaded sleeve 10 sleeved on the first screw rod 9 and threadedly connected to the first screw rod 9, and also includes a second ring body 1001 fixed to the threaded sleeve 10, the second ring body 1001 is slidingly connected to the vertical shaft 7, and the end of the first spring 11 away from the first ring body 702 is connected to the second ring body 1001.

[0048] During the switch durability test, the hydraulic cylinder 5 plays a key driving role. When the hydraulic cylinder 5 starts and drives the lifting plate 4 to descend, the pressure head 8 connected to the lifting plate 4 moves downward accordingly, pressing down on the switch assembly. In this process, the downward pressing action of the pressure head 8 causes the vertical shaft 7 to slide relative to the assembly plate 6. Specifically, under the guidance of the assembly plate 6, the vertical shaft 7 slides along a predetermined trajectory to adapt to the downward pressing movement of the pressure head 8. At the same time, the first spring 11 is compressed, resulting in a certain amount of elastic deformation. The compression of the first spring 11 not only plays a buffering role, reducing the impact force during the downward pressing process, but also provides a basis for subsequent test pressure adjustment.

[0049] To effectively adjust the applied pressure, the operator can rotate the first screw 9. The rotation of the first screw 9 causes the threaded sleeve 10 to slide up and down on the vertical shaft 7. The sliding of the threaded sleeve 10 further drives the second ring body 1001 to move on the vertical shaft 7. The key here is to adjust the distance between the second ring body 1001 and the first ring body 702. When the second ring body 1001 approaches the first ring body 702, the distance between the two decreases, which causes the initial compression of the first spring 11 to increase. If the travel of the hydraulic cylinder 5 remains unchanged, the greater the initial compression of the first spring 11, the greater the pressure that the pressure head 8 ultimately applies to the switch assembly. Conversely, when the distance between the second ring body 1001 and the first ring body 702 increases, the initial compression of the first spring 11 decreases, and the pressure of the pressure head 8 on the switch assembly also decreases.

[0050] This design allows personnel to flexibly adjust the pressure applied to the switch assembly during testing, effectively controlling this critical variable. By precisely adjusting the distance between the second ring body 1001 and the first ring body 702, test data can be obtained under varying pressures. This data more comprehensively reflects the durability performance of the switch assembly under varying pressure conditions, providing a rich and accurate reference for evaluating switch durability and facilitating comprehensive analysis and assessment of the switch assembly's quality and reliability.

[0051] Regarding the adjustment of the parameter of applied pressure, in specific implementation, the pressure can also be adjusted by controlling the oil filling amount of the adjustment cylinder.

[0052] As another embodiment of the present invention, a method for testing the durability of a switch in a smart energy station is also proposed, using the aforementioned testing equipment, comprising the following steps: Step 1: Preparation: Place the switch assembly on the placement position 1601, insert the frame 2 into the outer shell 1, and the elastic drive mechanism automatically triggers the fastening mechanism to clamp and fix it; Step 2: Pressure adjustment: adjust the initial compression of the first spring 11 to set the pressure; Step 3: Test execution: the hydraulic cylinder 5 is started to intermittently press the switch assembly to simulate the actual pressing condition; Step 4: Data collection and analysis: collect data on the number of presses, pressure changes, and current and voltage fluctuations to analyze and evaluate the durability of the switch components; Step 5: After the test is completed, the frame 2 is pushed out of the outer shell 1, the clamping mechanism is released, and the switch assembly is removed.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0054] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution.
