Description

Technical Field

[0001] The utility model relates to the field of lead-acid batteries, in particular to a lead-acid battery grid suitable for low-temperature operation. Background Art

[0002] Lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. The working principle of lead-acid battery is to convert chemical energy directly into electrical energy and achieve recharging through reversible chemical reactions. It is a secondary battery, that is, a battery that can be repeatedly charged and discharged. The main advantages of lead-acid batteries include stable voltage and low price. The grid is the main component of lead-acid battery and is the current collecting skeleton of the electrode. It plays the role of conducting, collecting and evenly distributing current. At the same time, it supports the active substance and is the carrier of the active substance.

[0003] After searching, a battery grid structure with a publication number of CN212783517U is found, which specifically discloses a battery grid structure, including a grid, wherein the grid is formed by a plurality of transverse ribs and longitudinal ribs interwoven with each other, and the grid is divided into an upper area, a middle area and a lower area from top to bottom, and the area ratio of the upper area, the middle area and the lower area on the grid is 3:3:5, and the widths of the longitudinal ribs in the upper area, the middle area and the lower area decrease successively, and the overall structure of the grid is differentiatedly designed, so that the width of the longitudinal ribs in the upper area of ​​the grid is greater than the width of the longitudinal ribs in the middle area of ​​the grid, and the width of the longitudinal ribs in the middle area of ​​the grid is greater than the width of the longitudinal ribs in the lower area of ​​the grid. In this way, the problem of excessive corrosion of the upper grid due to the large current can be balanced, thereby ensuring that the upper and lower grids can keep in sync, thereby improving the service life of the grid.

[0004] During use, if the existing lead-acid battery grids are not subjected to low-temperature treatment when the lead-acid battery grids and lead-acid batteries are assembled, when encountering low-temperature conditions, the grid frame itself will be too fragile due to the influence of the low temperature, and will break after the current passes through. In addition, the above-mentioned comparative cases also lack the means to make the grids suitable for low-temperature environments. Therefore, after long-term use, the lead-acid batteries assembled from the lead-acid battery grids not only limit the overall scope of use, but also cause certain losses to the lead-acid batteries when low-temperature failures occur.

[0005] Therefore, it is necessary to invent a lead-acid battery grid suitable for low temperature operation to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a lead-acid battery grid suitable for low-temperature operation, wherein the I-shaped reinforcement ribs strengthen the toughness of the battery grid frame itself through the battery grid frame, the low-temperature resistant protective layer, the built-in grooves, the I-shaped reinforcement ribs and the thermal insulation protective layer, so that when the current passes through the battery grid frame in a low-temperature environment, the thermal insulation protective layer can also be passed through, so that the I-shaped reinforcement ribs can retain a certain amount of heat, thereby strengthening the resistance of the lead-acid battery grid to cold air in a low-temperature environment, avoiding the situation in which the grid frame itself is too fragile due to the influence of low temperature, and the grid frame is broken after the current passes through, thereby expanding the overall use range of the device and reducing the risk of low-temperature failures to the lead The effect of the loss caused by lead-acid batteries is to solve the problem in the prior art that during the use of lead-acid battery grids, if the lead-acid battery grids and lead-acid batteries are not subjected to low-temperature treatment when assembled, when encountering low-temperature conditions, the grid frame itself will be too fragile due to the influence of low temperature, and will break after current passes through. In addition, the above-mentioned comparative cases also lack the means to make the grids suitable for low-temperature environments. Therefore, after long-term use, the lead-acid batteries assembled from lead-acid battery grids not only limit the overall scope of use, but also cause certain losses to the lead-acid batteries when low-temperature failures occur.

[0009] The low-temperature resistant protective layer is arranged on the surface of the battery plate grid frame to enhance the low-temperature resistance of the battery plate grid frame. The battery plate grid frame is provided with a built-in groove, an I-shaped reinforcement rib is fixedly installed inside the built-in groove, and a thermal insulation protective layer is pasted on the outside of the I-shaped reinforcement rib.

[0010] Preferably, a transverse rib is fixedly installed inside the battery plate grid frame, and a longitudinal rib is fixedly installed on one side of the transverse rib.

[0011] Preferably, an upper oblique supporting rib is fixedly installed on one side of the exterior of the longitudinal rib plate, and a lower oblique supporting rib is fixedly installed on the other side of the exterior of the longitudinal rib plate.

[0016] 1. The utility model is provided with a battery plate grid frame, a low-temperature resistant protective layer, a built-in groove, an I-shaped reinforcement rib and a thermal insulation protective layer.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-5 A lead-acid battery grid suitable for low-temperature operation is shown, comprising a battery grid frame 1, one of the components used for assembly with a lead-acid battery;

[0028] The tab body 9 is arranged on the top of the battery plate grid frame 1 to assist the current flow of the lead-acid battery, and a connecting through hole 10 is opened on the outside of the tab body 9, and a corrosion-resistant protective layer 11 is pasted on the surface of the tab body 9;

[0029] A low temperature resistant protective layer 12 is arranged on the surface of the battery plate grid frame 1 to enhance the low temperature resistance of the battery plate grid frame 1. A built-in groove 13 is opened inside the battery plate grid frame 1. An I-shaped reinforcement rib 14 is fixedly installed inside the built-in groove 13. A thermal insulation protective layer 15 is pasted on the outside of the I-shaped reinforcement rib 14. When current passes through in a low temperature environment, it can also pass through the thermal insulation protective layer 15, allowing the I-shaped reinforcement rib 14 to retain a certain amount of heat, thereby enhancing the resistance of the lead-acid battery grid to cold air in a low temperature environment.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, a transverse rib plate 2 is fixedly installed inside the battery plate grid frame 1, and a longitudinal rib plate 3 is fixedly installed on one side of the transverse rib plate 2. The intersection of the transverse rib plate 2 and the longitudinal rib plate 3 completes the assembly of the battery plate grid frame 1, and an upper inclined supporting rib 4 is fixedly installed on one side of the outer side of the longitudinal rib plate 3, and a lower inclined supporting rib 5 is fixedly installed on the other side of the outer side of the longitudinal rib plate 3. The upper inclined supporting ribs 4 and the lower inclined supporting ribs 5 on both sides of the longitudinal rib plate 3 strengthen the resistance of the lead-acid battery grid itself and reduce the probability of deformation. A first protrusion 6 is arranged on the outside of the longitudinal rib plate 3, and a threaded rod 7 is fixedly installed on one end of the first protrusion 6. A second protrusion 8 is movably connected to the outside of the threaded rod 7. The intersection node of the transverse rib plate 2 and the longitudinal rib plate 3 is connected to the front and rear first protrusion 6 and the second protrusion 8 through the threaded rod 7. In this way, after the lead-acid battery is assembled, these protrusions can penetrate into the lead paste to enhance the connection strength between the lead paste and the battery plate grid frame 1, so that the lead paste is not easy to fall off.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the tab body 9 is tightly fitted with the corrosion-resistant protective layer 11. The material of the corrosion-resistant protective layer 11 is calcium alloy. The corrosion-resistant protective layer 11 enhances the corrosion resistance of the tab body 9 during current flow and extends the overall service life. The I-shaped reinforcement rib 14 is tightly fitted with the thermal insulation protective layer 15. The material of the thermal insulation protective layer 15 is polyamide. When current passes through in a low-temperature environment, it can also pass through the thermal insulation protective layer 15, allowing the I-shaped reinforcement rib 14 to retain a certain amount of heat, thereby enhancing the resistance of the lead-acid battery grid to cold air in a low-temperature environment.

The upper inclined supporting ribs 4 and the lower inclined supporting ribs 5 on both sides of the longitudinal ribs 3 strengthen the resistance of the lead-acid battery grid itself and reduce the probability of deformation. Then, the front and rear first protrusions 6 and the second protrusions 8 are connected by threaded rods 7 at the intersection of the transverse ribs 2 and the longitudinal ribs 3. In this way, after the lead-acid battery is assembled, these protrusions can penetrate into the lead paste to enhance the connection strength between the lead paste and the battery plate grid frame 1, so that the lead paste is not easy to fall off. Then, after the assembly is completed, the lead-acid battery grid and the lead-acid battery are assembled. When the lead-acid battery assembled using the lead-acid battery grid, the low-temperature resistant protective layer 12 attached to the outside of the battery plate grid frame 1 strengthens the low-temperature resistance of the grid to the low-temperature environment. Reduce the loss of the battery plate grid frame 1 caused by low temperature, and then set the I-shaped reinforcement rib 14 inside the battery plate grid frame 1 to strengthen the toughness of the battery plate grid frame 1 itself, so that when the current passes through in a low temperature environment, it can also pass through the thermal insulation protective layer 15, so that the I-shaped reinforcement rib 14 can retain a certain amount of heat, and enhance the resistance of the lead-acid battery grid to cold air in a low temperature environment, and then the surface of the ear body 9 is also pasted with a corrosion-resistant protective layer 11, and the corrosion-resistant protective layer 11 enhances the corrosion resistance of the ear body 9 when current is flowing, and extends the overall service life. Finally, after completing the installation and use of all lead-acid battery grids according to the above operations, the device is maintained daily, wherein the material of the corrosion-resistant protective layer 11 is: calcium alloy, the material of the low-temperature resistant protective layer 12 is: high and low temperature resistant nano, and the material of the thermal insulation protective layer 15 is: polyamide, and the use process of the lead-acid battery grid suitable for low temperature work is completed.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
