AI Technical Summary
The internal flat test plate of the pressure cylinder in traditional high-acceleration testing machines ensures that the bottom surface of the sample is in 100% contact with the plate. The lack of a structure to control and reduce the contact area severely hinders steam flow, resulting in significant deviations in the test results.
The raised support structure formed by the rotating rod and the clamping rod ensures that the bottom of the sample only contacts the rod. The 'flat-raised' state switching is achieved through the parallelogram linkage principle, which creates a continuous airflow channel and improves the steam flow rate and heat exchange coefficient.
It effectively eliminates the 'contact thermal resistance' and 'moisture shielding effect', making the temperature, humidity, pressure and other parameters of the bottom surface of the sample highly similar to the environment inside the pressure cylinder, thereby improving the uniformity and reliability of the test results.

[0003] The internal flat test plate of the pressure cylinder in traditional high-acceleration testing machines ensures that the bottom surface of the sample is in 100% contact with the plate. The lack of a structure to control and reduce the contact area severely hinders steam flow, resulting in significant deviations in the test results. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy storage high-acceleration testing machine, comprising a main body of the device and four moving wheels disposed at the lower corners of the main body for movement;
[0006] A controller is provided on the upper left side of the main body of the device. Multiple control buttons are provided on the right side of the controller. A pressure gauge is provided on the lower left side of the controller. A pressure relief valve is provided below the pressure gauge. A water inlet is provided below the pressure relief valve.
[0007] The main body of the device is powered by an external power source. A sealed door is movably connected to the front middle of the main body of the device. A pressure cylinder is installed inside the front middle of the main body of the device. An internal space is opened inside the pressure cylinder, and an air heater is installed at the connection between the inner side of the internal space and the main body of the device.
[0008] A test plate is provided on the lower inner side of the pressure cylinder;
[0009] The device body has a water inlet and a drain outlet located on the lower left rear side.
[0010] The test plate has a sliding plate inside its lower side. Rotating rods and locking rods are equidistantly arranged on the upper side of the sliding plate. The ends of the multiple rotating rods and locking rods are movably connected. The locking rod on the rear side is connected to the inner side of the device body with a connecting end. The test plate and the multiple rotating rods and locking rods on the lower side are respectively provided with multiple slots at the vertically overlapping positions.
[0011] Preferably, the lever and the connecting end are movably connected, and the lever can rotate on the connecting end.
[0012] Preferably, multiple locking rods and rotating rods are movably connected, and the rotating rods and locking rods form a linkage structure.
[0013] Preferably, the multiple rotating rods and the slide plate are connected by a movable connection, the rotating rods can rotate on the slide plate, and the multiple rotating rods and the locking rods can protrude from the test plate through slots.
[0014] Preferably, the test board has protrusions on both the left and right sides of its lower side, and the slide plate is movably connected to the protrusions on both sides of the lower side of the test board by a sliding engagement method.

[0017] Compared with the prior art, this utility model provides an energy storage type high-acceleration testing machine, which has the following beneficial effects:
[0018] 1. Traditional flat test plates result in 100% contact area between the bottom surface of the sample and the plate, severely hindering steam flow and leading to significant deviations in test results. This innovative structure, however, utilizes a raised support formed by a rotating rod and a clamping rod, ensuring that the bottom of the sample only contacts the rod, greatly reducing the contact area. During testing, steam can flow freely at the bottom of the sample, effectively eliminating "contact thermal resistance" and the "moisture shielding effect," making the temperature, humidity, and pressure parameters at the bottom of the sample highly similar to the actual environment inside the pressure cylinder.
[0019] 2. The raised structure creates a continuous airflow channel at the bottom of the sample. Based on fluid mechanics principles, the steam velocity is significantly increased, thereby greatly improving the heat exchange coefficient of the sample's bottom surface. This results in more uniform heating and humidification of the sample during testing, avoiding localized test data anomalies and effectively improving the uniformity and reliability of test results, especially for materials sensitive to temperature and humidity.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides, for example Figure 1-5The energy storage high-acceleration testing machine shown includes a main body 16 and four casters 15 located at the lower corners of the main body 16 for movement. A controller 1 is located on the upper left side of the main body 16. Multiple control buttons 2 are located on the right side of the controller 1. A pressure gauge 4 is located on the lower left side of the controller 1. A pressure relief valve 5 is located below the pressure gauge 4. A water inlet 6 is located below the pressure relief valve 5. The user can add water through the water inlet 6. A water tank is installed inside the main body 16, and water can be added to the water tank through the water inlet 6.
[0028] The main body 16 of the device is powered by an external power source. A sealing door 17 is movably connected to the front middle of the main body 16. A pressure cylinder 10 is installed inside the front middle of the main body 16. An internal space is opened inside the pressure cylinder 10. An air heater 11 is installed at the connection between the inner side of the internal space and the main body 16. A test plate 24 is installed on the lower inner side of the pressure cylinder 10.
[0029] In addition, a water inlet 20 and a drain outlet 21 are respectively provided on the lower left rear side of the main body 16 of the device.
[0030] A tri-color light 3 is electrically connected to the upper right side of the top of the main body 16. Cooling fans 14 are built into the lower middle side and the upper left and right sides of the rear end of the main body 16. Pressure relief ports 18 are provided on the upper side of the water inlet 20 and the drain outlet 21. A right alarm interface panel 19 is built into the lower right side of the rear side of the main body 16. The alarm interface panel 19 has a built-in buzzer, timer, TS terminal, self-resetting fuse and multiple USB ports. A circuit breaker 22 is provided on the lower side of the alarm interface panel 19.
[0031] Optionally, the water inlet 20 is located at the lower left rear end of the main body 16 of the device and is connected to an external pure water source.
[0032] The drain outlet 21 is connected to the bottom of the pressure cylinder 10. After the test, the wastewater (including condensate and impurities) is discharged by steam pressurization. It is also connected to the drainage tank built into the main body of the device 16 to avoid wastewater residue corroding the equipment.
[0033] Optionally, the alarm interface panel 19 is located on the lower right side of the rear side of the main body 16, and has a built-in buzzer, timer, TS terminal, self-resetting fuse and USB interface.
[0034] Among them, the buzzer will sound an alarm when it detects faults such as over-temperature, over-pressure, or low water level;
[0035] The cumulative timer records the equipment's total operating time and is used for maintenance cycle reminders;
[0036] The TS terminal is connected to the sample power control terminal to ensure that the sample is powered on and the equipment is operating in sync.
[0037] Historical data (such as temperature and humidity curves) can be exported via USB interface, and USB flash drive storage is supported.
[0038] In this embodiment, the user injects pure water into the pressure cylinder 10 through the water inlet 20. Subsequently, samples such as electronic components and PCB boards can be placed on the test plate 24 to ensure that no conductive dust falls off.
[0039] Set the temperature, pressure, and humidity using controller 1, and select the control mode.
[0040] During the experiment, the air heater 11 heats the water in the pressure cylinder 10 to generate high-temperature and high-pressure steam, which is then evenly distributed to the test chamber through the guide structure.
[0041] Pressure gauge 4 displays the pressure in real time. When the pressure exceeds the set value, the pressure relief valve 5 can be opened automatically or manually, and steam is discharged through the pressure relief port 18.
[0042] The buzzer on the alarm interface panel 19 monitors for abnormalities in real time. If the temperature exceeds 135℃, the over-temperature protection sensor will trigger an alarm and shut down the device.
[0043] Cooling fan 14 provides forced cooling to the electrical control room and heating elements, maintaining the external temperature of the equipment at ≤40℃.
[0044] At the end of the test, the pressure is released to 0MPa through the pressure relief valve 5. After the mechanical pressure gauge shows 0MPa, the sealing door 17 is opened and the drain outlet 21 is opened to discharge the wastewater in the pressure cylinder 10 to avoid water accumulation and corrosion.
[0045] At this point, the user can remove the sample to observe the aging condition (such as weld cracking) and export the data through the USB interface of controller 1.
[0046] The test plate 24 has a slide plate 7 inside its lower side. The upper side of the slide plate 7 has rotating rods 9 and locking rods 8 equidistantly arranged. The ends of the multiple rotating rods 9 and locking rods 8 are movably connected. The locking rod 8 on the rear side is connected to the inner side of the device body 16 with a connecting end 23. The test plate 24 and the multiple rotating rods 9 and locking rods 8 on the lower side have multiple slots 12 at their vertically overlapping positions.
[0047] like Figure 1-5As shown, the locking rod 8 and the connecting end 23 are movably connected, and the locking rod 8 can rotate on the connecting end 23. Multiple locking rods 8 and rotating rods 9 are movably connected respectively. The rotating rods 9 and locking rods 8 form a linkage structure through transmission. Multiple rotating rods 9 and the sliding plate 7 are movably connected at their connection points. The rotating rods 9 can rotate on the sliding plate 7. Multiple rotating rods 9 and locking rods 8 can protrude from the test plate 24 through the slot 12. The left and right ends of the lower side of the test plate 24 protrude. The sliding plate 7 is movably connected to the protruding ends of the lower side of the test plate 24 through a sliding embedding method. The sliding plate 7 can move back and forth with a certain resistance at the protruding ends. A handle 13 is fixedly provided at the front end of the sliding plate 7.
[0048] Optionally, the surfaces of the rotating rod 9 and the clamping rod 8 are covered with a polytetrafluoroethylene coating with a surface roughness Ra≤0.8μm to reduce the coefficient of friction with the sample and prevent scratching of precision components.
[0049] Preferably, the user can hold the handle 13 and push the slide plate 7 forward (towards the sealing door 17). At this time, the rotating rod 9 and the locking rod 8 converge towards the center through the linkage structure (hinged) to form a bulge, and protrude from the surface of the test plate 24 through the slot 12.
[0050] The user places the sample on the raised rotating rod 9 and clamping rod 8. At this time, the bottom of the sample only contacts the rod, and the contact area is reduced by the number and spacing of the rod.
[0051] During the test, steam flows freely at the bottom of the sample, eliminating the "contact thermal resistance" and "moisture shielding effect", making the temperature and humidity of the bottom surface of the sample closer to the environment inside the pressure cylinder.
[0052] After the test, the user can pull the handle 13 to reset the slide plate 7, and lay the rotating rod 9 and the locking rod 8 flat to lower the height so that the sample can be removed.
[0053] Because traditional test plates have a planar structure, the bottom surface of the sample is in contact with the test plate for 100% of the area, which prevents steam from effectively reaching the contact surface and causes test deviations.
[0054] This structure achieves the switching between "flat" and "raised" states through the parallelogram linkage principle (the hinged connection of the rotating rod 9 and the locking rod 8 forms a deformable frame). When the slide plate 7 moves, the locking rod 8 rotates around the connecting end 23, driving the rotating rod 9 to move synchronously, and finally all the rods form a continuous support surface in the middle area.
[0055] The raised structure creates a continuous airflow channel at the bottom of the sample, increasing the steam velocity. According to fluid mechanics principles, this increases the heat exchange coefficient at the bottom of the sample, thereby improving the uniformity of the test.
[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
