[0031] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0032] Reference Figures 1-5 This invention illustrates an ignition testing device, comprising a movable support 1, a control box 2, a guide rail 3, an igniter fixing rod 4, and a probe fixing rod 5.
[0033] The control box 2 is mounted on the movable support 1;
[0034] The guide rail 3 is slidably disposed along the height direction of the movable support 1 and can be locked to the movable support 1; the track direction of the guide rail 3 is perpendicular to the height direction of the movable support 1.
[0035] The igniter fixing rod 4 is slidably arranged along the track direction of the guide rail frame 3 and is driven by the driving component 37; an igniter 6 is provided at one end of the igniter fixing rod 4; the igniter 6 and the driving component 37 are electrically connected to the control box 2 respectively;
[0036] The probe fixing rod 5 is arranged parallel to the igniter fixing rod 4 and slidably mounted on the guide rail frame 3. A detector 7 is provided at one end of the probe 5 near the igniter 6. The detector 7 is electrically connected to the control box 2.
[0037] In the embodiments of this application, a movable bracket 1, a control box 2, a guide rail frame 3, an igniter fixing rod 4, and a probe fixing rod 5 are used. The control box 2 is disposed on the movable bracket 1. The guide rail frame 3 is slidably disposed along the height direction of the movable bracket 1 and can be locked to the movable bracket 1. The track direction of the guide rail frame 3 is perpendicular to the height direction of the movable bracket 1. The igniter fixing rod 4 is slidably disposed along the track direction of the guide rail frame 3 and is driven by a driving component 37. An igniter 6 is disposed at one end of the igniter fixing rod 4. The igniter 6 and the driving component 37 are electrically connected to the control box 2. The probe fixing rod 5 is disposed parallel to the igniter fixing rod 4 below and slidably disposed on the guide rail frame 3. A detector 7 is disposed at the end of the probe fixing rod 5 near the igniter 6. The detector 7 is electrically connected to the control box 2. The movable support 1 and guide rail 3 are arranged perpendicularly to each other. The guide rail 3 can slide and adjust along the height of the movable support 1, which drives the igniter fixing rod 4 and the probe fixing rod 5 to adjust their heights up and down synchronously. This allows the height of the igniter 6 and the detector 7 to be adjusted according to the size of the test sample. By sliding the igniter fixing rod 4 along the guide rail 3 and driving it to slide through the drive component 37, the horizontal position of the igniter 6 can be automatically adjusted according to the sample size and installation position. The probe fixing rod 5 can be slidably positioned below the igniter fixing rod 4, allowing the position of the detector 7 to be adjusted according to the sample. This makes the device suitable for testing samples of different sizes, increasing its usability. By electrically connecting the igniter 6 and the detector 7 to the control box 2, the ignition frequency can be controlled, and the flame status can be monitored in real time through the detector 7. This enables the automatic movement of the igniter 6 to adjust its position, allowing the sample to be fully evaluated and better meet standard requirements. This achieves unmanned testing, improves testing quality and efficiency, and is simple and convenient to operate.
[0038] The ignition test apparatus in this exemplary embodiment will now be further described.
[0039] In this embodiment, the movable support 1 includes a base 11 and a vertical frame 12. The base 11 is equipped with lockable casters at its bottom, allowing the device to be moved to any position. The control box 2 is mounted on the base 11. The vertical frame 12 is fixed to one side of the base 11. Preferably, the vertical frame 12 is U-shaped and has two integrally connected columns, serving as a movable support for the guide rail frame 3. It has a certain height, allowing the guide rail frame 3 to be adjusted over a wide range of heights.
[0040] In this embodiment, the guide rail frame 3 is slidably arranged along the vertical frame 12, including a horizontal guide rail plate 31 and a guide wheel assembly. The length of the horizontal guide rail plate 31 is perpendicular to the height of the vertical frame 12, and one side of it is slidably connected to the vertical frame 12 via a sliding plate 13. Specifically, the sliding plate 13 is U-shaped, with its closed side connected to one side of the horizontal guide rail plate 31, and its opposite sides respectively abutting against two columns of the vertical frame 12, and locked in place by means of bolts or other locking devices through waist holes. Thus, when it is necessary to slide the horizontal guide rail plate 31 up and down, the bolts are loosened, adjusted to a suitable height, and then the bolts are tightened to fix it.
[0041] The guide wheel assembly is located on the other side of the transverse guide rail plate 31, including multiple driven wheels 32 and at least one driving wheel 33. The multiple driven wheels 32 are rotatably mounted on the transverse guide rail plate 31 and arranged horizontally at intervals. The driving wheel 33 is located above one of the driven wheels 32 and is connected to the driving member 37 for transmission. The igniter fixing rod 4 is horizontally positioned between the driving wheel 33 and the driven wheels 32, and is in contact with the driving wheel 33 and the multiple driven wheels 32. The driving member 37 drives the driving wheel 33 to rotate, thereby providing a horizontal moving force to the igniter fixing rod 4. The multiple driven wheels 32 are in contact with the lower part of the igniter fixing rod 4, which can support it and also assist the igniter fixing rod 4 in horizontal movement, making its movement smooth. An igniter 6 is installed at one end of the igniter fixing rod 4. The igniter 6 and the driving component 37 are electrically connected to the control box 2. By electrically connecting the driving component 37 to the control box 2, the movement of the igniter 6 can be automatically controlled at the speed required by the standard, driving the igniter 6 to move back and forth relative to the sample being tested (such as a BESS battery), and adjusting the flame distance of the igniter 6 from the sample. Furthermore, the control box 2 enables automatic ignition of the igniter 6, reducing the danger of manual ignition operation, and also allows control of the ignition frequency as needed (the standard requirement is 10 seconds / time).
[0042] As an example, the drive unit 37 is a DC motor, located on the side of the transverse guide plate 31 facing the vertical frame 12, and near the transverse center of the transverse guide plate 31. The drive wheel 33 is correspondingly located at the center of the transverse guide plate 31 to improve the horizontal adjustment stability of the igniter fixing rod 4.
[0043] Furthermore, the driven wheels 32 are preferably configured as three, located in the middle and at both ends of the transverse guide plate 31, respectively, to ensure the stable support of the igniter fixing rod 4.
[0044] As an example, a cover plate 34 is detachably provided on the side of the transverse guide plate 31 away from the vertical frame 12. The detachably connected cover plate 34 can shield the guide wheel assembly and avoid affecting its operation. The detachable method can be a bolt, fastener, or other connection method.
[0045] As an example, limit switches 35 are provided at both ends of the transverse guide plate 31; the limit switches 35 are electrically connected to the control box 2; two limit blocks 41 are slidably arranged on the igniter fixing rod 4. Through the cooperation of the limit blocks 41 and the limit switches 35, the automatic ignition position of the igniter 6 can be fixed. Specifically, according to the installation position of the sample under test, the distance between the two limit blocks 41 is adjusted. In the initial state, the limit block 41 near the igniter 6 is in contact with the limit switch 35 near the igniter. When the igniter fixing rod 4 moves towards the sample side until the limit block 41 at the far end is in contact with the limit switch 35 at the far end, the control box 2 sends a closing command to the DC motor, causing it to stop and no longer drive the igniter fixing rod 4 to move. Ultimately, this ensures that the distance between the igniter 6 and the sample can be maintained at the standard requirement of 12.7 mm, thereby improving the test quality.
[0046] It should be noted that the contact surfaces of the limit block 41 and the igniter 6 adjustment rod have a certain frictional resistance. For example, the contact surfaces can be made of materials such as silicone rubber, which can be pushed by force, but cannot move on its own without external force, thus maintaining a stable position and preventing displacement when in contact with the limit switch 35, which would lead to inaccurate test accuracy.
[0047] In this embodiment, the probe fixing rod 5 is movably inserted through both ends of the bottom of the transverse guide rail plate 31 and fixed by a limiting ring 51. A detector 7 is provided at the end near the igniter 6, allowing the detector 7 to be horizontally adjusted according to the size and position of the sample, making adjustment simple and convenient. The detector 7 is electrically connected to the control box 2, enabling real-time monitoring of the flame status to ensure the flame temperature meets standards. It is understood that the detector 7 can be a composite flame detector as in the prior art, capable of responding to two or more fire parameters, i.e., simultaneously detecting flame and temperature.
[0048] As an example, the bottom ends of the transverse guide plate 31 have connecting ears 36 extending downwards, and the probe fixing rod 5 is movably inserted through the two connecting ears 36. Two limiting rings 51 are provided and sleeved on the probe fixing rod 5. The limiting rings 51 can slide on the probe fixing rod 5, and their contact surfaces with the probe fixing rod 5 have a certain frictional resistance. For example, the contact surface can be made of silicone rubber, so that after being adjusted to a suitable position, it can remain stationary without the application of external force, thus fixing the probe fixing rod 5 in that suitable position. Specifically, the detector 7 first adjusts the front and rear distance of the probe fixing rod 5 by moving it according to the installation position of the sample being tested, and then moves the two limiting rings 51 to the outside of the two connecting ears 36 to limit and fix the probe fixing rod 5.
[0049] As an example, the detector 7 is detachably mounted on the probe fixing rod 5 via an angle adjustment bracket 8, making the detector 7 detachable for inspection or replacement, as well as convenient for storage and transportation, reducing damage.
[0050] Specifically, the angle adjustment bracket 8 includes a first slider 81, a first rod 82, a second slider 83, and a second rod 84. The first slider 81 is slidably sleeved on the probe fixing rod 5; the first rod 82 is fixedly inserted through the first slider 81; the second slider 83 is rotatably sleeved on one end of the first rod 82; the second rod 84 is fixedly inserted through the second slider 83; and the detector 7 is disposed on the top of the second rod 84. The contact surfaces between the first slider 81 and the probe fixing rod 5, and between the first rod 82 and the second slider 83, have a preset frictional force. That is, the entire angle adjustment bracket 8 and the detector 7 can be removed from the probe fixing rod 5 by using the first slider 81, and the detector 7 can be rotated by rotating the second slider 83 to adjust the angle, making it tilted to align with the flame outlet of the igniter 6 for accurate detection of the flame state.
[0051] As an example, the igniter 6 is mounted on the igniter fixing rod 4 via an igniter bracket 9, and the igniter 6 is detachably connected to the igniter bracket 9.
[0052] Specifically, the igniter bracket 9 includes a mounting block 91 and a connecting rod 92. The mounting block 91 is movably inserted through the end of the igniter fixing rod 4 and has a certain frictional resistance with it. The connecting rod 92 is inserted through the mounting block 91, and one end of the connecting rod 92 is detachably connected to a mounting piece 93, which can be connected by bolts or other connecting parts. The igniter 6 is fixedly inserted through the mounting piece 93. That is, the mounting block 91 can be removed from the igniter fixing rod 4, and the igniter 6 can also be removed from the igniter bracket 9, which facilitates maintenance, replacement, or transportation.
[0053] The working principle of this application embodiment:
[0054] Install the household energy storage battery (BESS). Adjust the height of the igniter 6 by moving the guide rail 3 up and down to a suitable height and then fix it in place. Adjust the position of the detector 7 by moving the probe fixing rod 5 horizontally to a suitable position and then keep it in place. After adjusting the igniter fixing rod 4 and the two limit blocks 41 to a suitable position (confirming that the distance between the sample and the igniter 6 is 12.7mm), drive the igniter 6 to move to the initial position via the drive component 37. Set the ignition frequency, test time, igniter 6 moving speed, and other relevant parameters on the control box 2 screen. Start the equipment and begin the test. The igniter 6 automatically moves towards the energy storage battery at the standard required speed to achieve automatic ignition until the standard required time is completed. The test process does not require manual ignition or monitoring. After the test is completed, remove the sample and evaluate the ignition performance of the BESS.
[0055] The testing device of this application has a simple structure, is easy to operate, and has a long range of vertical and horizontal movement, making it suitable for testing samples of different sizes and increasing the usability of the device. The device has a fixed igniter 6 that can move automatically at the speed required by the standard to achieve automatic ignition and monitor the ignition situation, so that the sample can be fully evaluated and better meet the standard requirements. It realizes unmanned testing, reduces the danger of manual operation, and improves the efficiency and stability of testing.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
