DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 5 The utility model discloses an alkaline battery gas evolution measuring device, comprising a base 1, a water storage tank 2 for water injection is provided on the top of the base 1, a support seat 3 for supporting the battery is provided in the water storage tank 2, the outer wall of the support seat 3 and the inner wall of the water storage tank 2 are fixedly connected by a support rod 4, a gas evolution pipe 5 for covering the battery is sleeved on the outer side of the support seat 3, the outer wall of the gas evolution pipe 5 is provided with scale lines, and the top of the gas evolution pipe 5 is connected to an exhaust assembly 6.

[0026] In this embodiment, when in use, water is first injected into the water storage tank 2, and the water is submerged above the support rod 4, and then the alkaline battery is placed on the support seat 3, and then the gas analysis tube 5 is covered on the outside of the support seat 3. Finally, it is left to stand for a period of time, and the gas analysis amount of the alkaline battery can be measured by observing the drop of the water level line in the gas analysis tube 5.

[0027] When the gas analysis tube 5 is under the cover, because there is air in the gas analysis tube 5, under the action of air pressure, the air will block the water and prevent the water from entering the gas analysis tube 5. At this time, the gas released by the alkaline battery will increase the volume of the air in the gas analysis tube 5, so that the original gas will escape from the gas analysis tube 5, which will cause the total amount of air in the gas analysis tube 5 to be unable to change effectively when the alkaline battery self-discharges and releases gas.

[0028] By tilting the gas analysis tube 5, the pressure at the bottom pipe opening of the gas analysis tube 5 is unbalanced, allowing some liquid to enter the gas analysis tube 5. However, after this operation, the height of the liquid entering the gas analysis tube 5 cannot exceed the water level line in the water storage tank 2. In addition, the presence of the support seat 3 in the gas analysis tube 5 will interfere with the inclination amplitude of the gas analysis tube 5, further reduce the water entering the gas analysis tube 5, and make the water level line in the gas analysis tube 5 much lower than the water level line in the water storage tank 2. In this way, when the alkaline battery is gassing, although the air in the gas analysis tube 5 will be effectively increased, because the water level line in the gas analysis tube 5 is pressed below the water level line in the water storage tank 2, it will affect the data observation of the evolved gas, thereby causing inaccurate detection data of the alkaline battery.

[0029] Therefore, an exhaust component 6 is connected to the top of the gas analysis tube 5. The active exhaust of the exhaust component 6 is used to generate negative pressure in the gas analysis tube 5, so that water is actively sucked into the gas analysis tube 5. In combination with the scale lines set on the outer wall of the gas analysis tube 5, the water level and the scale line positions are kept precisely fitted. At this time, when the alkaline battery is gassing and the air in the gas analysis tube 5 increases, the water level line can be clearly seen to drop, which can effectively reduce the difficulty of observation and improve the measurement accuracy of the gas evolution of the alkaline battery.

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, the exhaust assembly 6 includes a pressure cylinder 61, a rotor 62, a pressure plate 63 and an adjusting wheel 64. The bottom of the pressure cylinder 61 is connected to the gas analysis pipe 5, and the top of the pressure cylinder 61 is fixedly connected to the exhaust pipe 7 for exhaust. The rotor 62 is rotatably connected inside the pressure cylinder 61, and a plurality of grooves 8 are provided in a circular array on the outer wall of the rotor 62. The pressure plate 63 in contact with the inner wall of the pressure cylinder 61 is slidably connected inside the groove 8, and the outer wall of the pressure cylinder 61 is provided with an adjusting wheel 64 connected to the rotor 62.

[0031] In this embodiment, the rotor 62 and the pressure plate 63 are provided, and the pressure plate 63 is in contact with the inner wall of the pressure cylinder 61, so that when the rotor 62 rotates, the pressure plate 63 slides along the inner wall of the pressure cylinder 61. Figure 2 It can be found that when the pressing plate 63 slides along the inner wall of the pressure cylinder 61, the space between two adjacent pressing plates 63 will gradually change. When the space between two adjacent pressing plates 63 increases, the gas inside will be stretched to generate negative pressure, and then the external air will be sucked between the two pressing plates 63, thereby playing the role of sucking air. Therefore, the pressure cylinder 61 is set at the top of the gas analysis tube 5 and keeps in communication with the gas analysis tube 5. At the same time, the top of the pressure cylinder 61 is provided with an exhaust pipe 7, which can suck the air in the gas analysis tube 5 into the pressure cylinder 61 and then discharge it through the exhaust pipe 7, so as to achieve the effect of sucking water into the gas analysis tube 5.

[0032] By arranging an adjusting wheel 64 connected to the rotor 62 on the outer side of the pressure cylinder 61, the rotation of the rotor 62 can be actively controlled, making the control of the water inlet amount in the gas analysis pipe 5 simpler and more convenient.

[0033] In a further preferred embodiment of the present invention, Figure 2 As shown, the axis of the pressure cylinder 61 and the axis of the rotor 62 are located on the same horizontal line, and the axis of the rotor 62 is located on the outer peripheral side of the axis of the pressure cylinder 61.

[0034] In this embodiment, Figure 2 As shown, by making the axis of the rotor 62 located on the outer peripheral side of the axis of the pressure cylinder 61, the rotor 62 and the pressure cylinder 61 can be eccentrically arranged, so that the distance between the outer wall of the rotor 62 and the inner wall of the pressure cylinder 61 changes. Therefore, when the rotor 62 rotates, the pressure plate 63 located on the side of the rotor 62 close to the pressure cylinder 61 will be squeezed by the inner wall of the pressure cylinder 61 and slide into the groove 8, and as the rotor 62 rotates, it gradually enters the side of the outer wall of the rotor 62 away from the inner wall of the pressure cylinder 61, so that the space between two adjacent pressure plates 63 gradually decreases and then gradually increases.

[0035] By arranging the axis of the rotor 62 and the axis of the pressure cylinder 61 to be on the same horizontal plane, the distances between the top and bottom of the rotor 62 and the inner wall of the pressure cylinder 61 can be symmetrical along the axis, and the left and right sides will be wider on one side and narrower on the other side, so that the observation Figure 2 It is found that when the rotor 62 rotates clockwise, the pressure plate 63 on the right side of the rotor 62 will gradually move to the left side, and when it moves to the leftmost side, the extended length of the pressure plate 63 is the largest. Therefore, before the pressure plate 63 moves to the leftmost side, the space between the two adjacent pressure plates 63 will gradually increase, thereby generating negative pressure to suck the air in the gas analysis tube 5. When the pressure plate 63 exceeds the leftmost side, the pressure plate 63 will be squeezed by the inner wall of the pressure cylinder 61 and slide into the groove 8, thereby reducing the space between the two adjacent pressure plates 63, causing the air to be compressed and pressurized, until the pressure plate 63 moves to the exhaust pipe 7, the air will be discharged to the outside, thereby realizing the air extraction of the gas analysis tube 5.

[0036] When too much air is sucked out and the water level line is submerged, it is necessary to add air into the gas analysis pipe 5 to level the water level line. At this time, the rotor 62 is rotated counterclockwise to allow the space between the two adjacent pressure plates 63 to absorb air from the exhaust pipe 7 and then discharge it into the gas analysis pipe 5 to complete the gas replenishment and make the gas analysis amount detection of the alkaline battery more accurate.

[0037] In a further preferred embodiment of the present invention, Figure 2As shown, the outer side walls of the rotor 62 and the pressure plate 63 are in close contact with the inner side wall of the pressure cylinder 61 , so that a closed cavity is formed between two adjacent pressure plates 63 .

[0038] In this embodiment, by making the rotor 62 and the pressure plate 63 in close contact with the inner wall of the pressure cylinder 61, the gap between the rotor 62 and the pressure plate 63 can be reduced, thereby preventing air from leaking through the gap, thereby preventing the alkaline battery intake volume from being falsely detected, and further improving the detection accuracy.

[0039] Because the pressure plate 63 and the rotor 62 are in close contact with the inner wall of the pressure cylinder 61, a closed cavity can be formed between two adjacent pressure plates 63, which can make the air intake and exhaust efficiency of the exhaust component higher and the water level line control accuracy in the gas analysis pipe 5 better.

[0040] In a further preferred embodiment of the present invention, Figure 4 As shown, a spring groove 9 is formed inwardly on the outer wall of the pressure plate 63 close to the rotor 62 , and a support spring 10 in contact with the inner wall of the groove 8 is connected to the spring groove 9 .

[0041] In this embodiment, a spring groove 9 is provided on the side of the pressure plate 63 close to the rotor 62, and a support spring 10 is provided between the spring groove 9 and the inner wall of the groove 8. The support spring 10 can be used to push the pressure plate 63 to always maintain close contact with the inner wall of the pressure cylinder 61 to ensure air tightness, thereby making the operation of the exhaust component 6 more stable.

[0042] In a further preferred embodiment of the present invention, Figure 1 and Figure 5 As shown, the adjusting wheel 64 is composed of a primary wheel 641 and a secondary wheel 642. The secondary wheel 642 is rotatably connected to the outer wall of the pressure cylinder 61. A circular groove is opened in the middle of the secondary wheel 642 and a tooth groove 11 is processed. A gear 12 is meshed on one side of the tooth groove 11. One side of the gear 12 is connected to the rotor 62 through a rotating shaft, and the other side is connected to the primary wheel 641 through a rotating shaft.

[0043] In this embodiment, a primary wheel 641 is provided to control the rotation of the rotor 62 so that the rotor 62 moves with the pressure plate 63 to discharge the air in the gas analysis pipe 5 .

[0044] And observe Figure 1 It can be found that a secondary wheel 642 is provided on the outside of the pressure cylinder 61, and the diameter of the secondary wheel 642 is larger than that of the primary wheel 641. Figure 5It can be found that a tooth groove 11 is provided in the secondary wheel 642, and meshes with the gear 12 connected to the primary wheel 641, and the number of teeth in the tooth groove 11 is much larger than the number of teeth in the gear 12, so that when the secondary wheel 642 rotates, the rotation angle of the primary wheel 641 will be larger, which can be suitable for increasing the rotation speed of the rotor 62 and increasing the exhaust speed of the exhaust component 6, so as to reduce the preparation time of the gas evolution detection of the alkaline battery, thereby improving the gas evolution detection efficiency of the alkaline battery.

[0045] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the top of the support base 3 is located above the top of the base 1, and a placement groove 13 for placing a battery is opened on the top of the support base 3.

[0046] In this embodiment, by making the top of the support seat 3 located above the top of the base 1, the alkaline battery can be placed above the water when placed on the support seat 3, thereby preventing the battery from being corroded by contact with water and affecting the detection accuracy of the gas evolution amount. By providing a placement groove 13 on the top of the support seat 3, it can be used to support the alkaline battery, so as to make the placement of the alkaline battery more stable.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
