Technical Field

[0001] The utility model belongs to the technical field of explosion-proof detection of batteries, and in particular relates to an ignition device for explosion-proof testing of batteries. Background Art

[0002] During the charging process of lead-acid batteries, the positive and negative electrodes react to produce oxygen and hydrogen respectively. If these gases are retained in the space above the battery pole group, they may cause fire or even explosion inside the battery when exposed to open flames, which will not only damage the battery itself, but also cause harm to the equipment and people around it. Therefore, the IEC (International Electrotechnical Commission) standard and national standards stipulate that for batteries that have been fully charged for 1 hour, continue to charge at a certain current, and use a 24V power supply to blow a fuse of corresponding specifications at a distance of 2-4mm from the exhaust port, and no combustion or explosion should occur inside the battery.

[0003] In this experiment, the fuse needs to be fixed at a position 2-4mm away from the exhaust port. However, in the actual experiment, the glass cover outside the fuse needs to be broken to expose the fuse, and then connected to the output line of the DC power supply. The fuse is thin and soft, and directly connecting the power line makes it impossible to fix the fuse in a certain position, and it is easy to be torn off by two wires.

[0004] The utility model patent with the authorization announcement number CN215678679U discloses an explosion-proof ignition device for lead-acid batteries, which includes a fuse replacement unit, which includes a receiving rod for placing the fuse, a receiving seat for placing the fuse, and a control member for manipulating the receiving seat. There are two receiving rods, and the receiving seat is located between the two receiving rods, and the control member is connected to the receiving seat. When in use, the fuse can be fixed between the two receiving rods, and the height of the support rod relative to the battery can be adjusted by rotating the hand wheel to drive the screw to rotate to meet the requirement of 2-4mm. Although the ignition device solves the drawbacks of the prior art that the fuse is directly connected to the power output line, it has a complex structure, occupies a large space, and it is difficult to control the appropriate screw rotation force to control the distance between the fuse and the exhaust port when in use, that is, there is a problem of poor practicality.

[0009] As a preferred solution of the present application, the fuse fixing seat is provided with a cable connector and a fuse receiving member, the cable connector is used to connect to the power line, and the fuse receiving member is used to clamp the fuse.

[0010] As a preferred solution of the present application, the fuse receiving member is a receiving groove arranged on the fuse fixing seat, and the receiving groove is formed by a flexible plate, or the receiving groove is a sunken groove.

[0022] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0023] This embodiment provides an ignition device for battery explosion-proof testing, such as Figure 1 As shown in or 3, the device includes a first panel 1 and a second panel 2, one side of the first panel 1 and the second panel 2 are connected to form a right angle frame, and the right angle frame can be snapped with the edge of the battery 7. It can be understood that the first panel 1 and the second panel 2 should be made of insulating material; an opening 3 is provided on the first panel 1 for leaking the exhaust port 8 of the battery 7. In this embodiment, the opening 3 is arranged on the first panel 1 near the connection between it and the second panel 2, and fuse fixing seats 4 are respectively provided on the upper surfaces of the first panel 1 and the second panel 2. The two groups of fuse fixing seats 4 are located on both sides of the opening 3, and the two groups of fuse fixing seats 4 can horizontally suspend the fuse 9 at a specified position directly above the exhaust port 8, and the specified position is 2-4mm between the fuse 9 and the exhaust port 8 specified in the test.

[0024] like Figure 2 As shown in FIG. 1 , the ignition device in this embodiment is used on the battery 7. Figure 2It can be seen that the right-angle frame is clamped on the edge of the battery 7 close to the exhaust port 8, the first panel 1 and the second panel 2 are clamped on the adjacent two sides of the battery 7 respectively, the exhaust port 8 leaks out through the opening 3, and the fuse 9 is horizontally suspended above the exhaust port 8 through two sets of fuse fixing seats 4 and is 2-4mm away from the exhaust port 8.

[0025] The fuse holder 4 is provided with a cable connector 41 and a fuse receiving part 42. The cable connector 41 is used to connect to the cable of the 24V power supply, and the fuse receiving part 42 is used to clamp the fuse 9. It can be understood that in this embodiment, the fuse holder 4 should be made of conductive material.

[0026] The fuse receiving member 42 is a receiving groove provided on the fuse fixing seat 4.

[0027] The receiving groove is formed by a flexible plate. Figure 1 As shown, the advantage of using a flexible board is that the depth or height of the receiving groove can be adjusted in real time according to actual needs to adapt to exhaust ports 8 of different heights (the heights of exhaust ports 8 of different types of batteries 7 are different, but the difference between them is millimeter level, so fine-tuning is required). In this embodiment, the constituent material of the flexible board is preferably but not limited to metal foil, for example, aluminum foil. In other embodiments of the present application, the constituent material of the flexible board may also be other elastic alloy materials.

[0028] Or, the receiving groove is a sunken groove arranged on the receiving seat of the fuse 9, such as Figure 3-4 As shown; in order to adapt to the exhaust ports 8 at different heights, a shift plate 6 may preferably be provided in the sunken groove, and the shift plate 6 can move in the sunken groove under the action of an external force, so that it is also convenient to fine-tune the height of the fuse 9 from the exhaust port 8 by fine-tuning the position of the shift plate 6 in the sunken groove; it can be understood that the friction force between the two sides of the shift plate 6 and the inner wall of the sunken groove should be greater than the sum of the gravity of the shift plate 6 and the fuse 9.

[0029] The shift plates 6 are preselected to be arranged in only one group. When there are multiple groups, the distance between two adjacent groups is greater than the diameter of the fuse 9 .

[0030] The fuse receiving part 42 is set as a sunken groove with a shift plate 6 or a plastic structure. Compared with the existing structure that uses a screw to drive the fuse receiving part 42 to rise and fall, the design of this embodiment can achieve a more accurate fine-tuning function on the one hand, and on the other hand, it simplifies the structure and reduces the cost.

[0031] The first panel 1 and the second panel 2 are respectively provided with locking screws 5, and the locking screws 5 are used as locking pieces to lock the first panel 1 and the second panel 2 with the battery 7, thereby improving the stability of the ignition device in fixing the fuse 9 on the exhaust port 8; this is a preferred embodiment of the present embodiment. In other embodiments of the present application, the first panel 1 and the second panel 2 can also be fixed to the battery 7 by bonding or other methods.

[0032] In order to facilitate determination of the height and position of the fuse holder 4, in this embodiment, the aperture of the opening 3 on the first panel 1 is preferably larger than the aperture of the exhaust port 8 on the battery 7, so that the exhaust port 8 is exposed as a whole. At the same time, the thickness of the first panel 1 corresponds to the height of the exhaust port 8. Thus, the height of the fuse 9 from the exhaust port 8 can be adjusted by simply adjusting the depth of the receiving groove, thereby reducing additional interference and simplifying the operating procedure.

[0033] The use principle of this embodiment includes:

[0034] When in use, the first panel 1 and the second panel 2 are respectively fixed on the battery 7 to be tested by the locking screws 5, and it is ensured that the exhaust port 8 is leaked out through the opening 3 as a whole; the tightening force of the locking screws 5 is based on ensuring that no damage is caused to the battery 7.

[0035] Then place the fuse 9 in the receiving groove and observe the height. According to the required height, slightly plasticize the receiving groove or slightly adjust the height of the shift plate 6 in the sunken groove to ensure that the fuse 9 is 2-4 mm away from the exhaust port 8. Finally, turn on the power switch to form a closed loop between the fuse holder 4, the fuse 9 and the power wire to perform ignition and explosion-proof tests.

[0036] In summary, it can be seen that compared with the prior art, the ignition device of this embodiment has a simple structure, is easy to operate, and is conducive to improving the detection accuracy.

[0037] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the premise of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of the claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
