[0003] At present, a Chinese patent with the announcement number CN216413141U discloses a flat-structure valve-regulated power lead-acid battery, which relates to the field of battery technology and includes a shell. A plurality of electrode groups are detachably connected inside the shell. The electrode groups are distributed in a flat shape. The electrode groups are connected in series to form a battery. The non-series poles at the two end electrode groups extend out of the shell to derive positive and negative output terminals. A safety valve is provided at the front end of the middle part of each group of electrode groups. Buffers are provided on both sides of the top of the electrode groups in a contact manner, with the tops fixed to the top of the shell.

[0004] The above-mentioned flat structure valve-regulated lead-acid battery still has some problems in use. Although it can reduce the space occupied by the battery itself and has a high use value, in winter, the weather is cold and the temperature inside the battery cannot be adjusted according to the weather temperature, thereby failing to increase the activity of the active substances in the battery, affecting the battery's capacity output. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 This embodiment provides a flat valve-regulated lead-acid battery, including a lead-acid battery body 100. A groove 103 is formed at the top of the lead-acid battery body 100. A plurality of vent tubes 104 are provided at the bottom of the groove 103. One end of the vent tube 104 is connected to the lead-acid battery body 100. A constant pressure assembly for balancing the air pressure in the lead-acid battery body 100 is connected to the mouth of the vent tube 104 via a detachable connector. A sealing assembly for sealing the groove 103 is provided at the mouth of the groove 103.

[0025] Among them, the constant pressure component includes a connecting pipe 300 sealed and inserted into the inner cavity of the air vent tube 104, a connecting plate 303 is fixedly connected to the inside of the connecting pipe 300, a connecting rod 304 is slidably inserted in the middle of the connecting plate 303, and a sealing plate 302 for sealing the mouth of the connecting pipe 300 is fixedly connected to the top of the connecting rod 304, a screw 305 is fixedly connected to the bottom of the connecting plate 303, and a counterweight 306 is threadedly connected to the surface of the screw 305. Through the setting of disassembly of the counterweight 306, the counterweight 306 can be removed and the weight of the counterweight 306 can be adjusted to set different air pressure balance thresholds. When in winter, the weight of the counterweight 306 can be increased under safe conditions to increase the air pressure balance threshold, so that more gas can be retained in the lead-acid battery body 100, thereby increasing the temperature inside the lead-acid battery body 100. Therefore, increasing the temperature inside the lead-acid battery body 100 can make the active material inside the lead-acid battery body 100 more active, thereby increasing the capacity output of the lead-acid battery body 100.

[0026] The lead-acid battery body 100 is flattened. In situations where space is limited, the flattened battery can better adapt to irregular installation spaces.

[0027] Furthermore, the closing component includes a cover plate 102 embedded in the mouth of the groove 103, and square holes 201 are opened on the top of both sides of the cover plate 102. The square holes 201 are provided with filter elements for preventing foreign particles in the external air from entering the groove 103. Through the setting of the closing component, the mouth of the groove 103 can be effectively closed to prevent external dust, moisture and other impurities from entering the groove 103, thereby protecting the constant pressure component and the air vent 104 from being affected by the external environment and ensuring their normal operation.

[0028] Furthermore, the filter element includes a filter layer 202 arranged in the inner cavity of two groups of square holes 201, wherein the filter layer 202 is one or two groups of non-woven fabrics, filter cotton, etc. Through the setting of the filter layer 202, the filter layer 202 in the filter element can effectively filter out fine impurity particles in the air, ensuring that the air entering the groove 103 is clean, thereby reducing pollution to the constant voltage component and the inside of the battery, and ensuring the stable performance of the battery.

[0029] Preferably, the inner cavities of the two groups of square holes 201 are fixedly connected with filter plates 200 on the upper and lower sides of the filter layer 202. The setting of the filter plates 200 can further improve the filtering effect, prevent the filter layer 202 from being damaged by large particles of impurities, and extend the service life of the filter element.

[0030] It is worth noting that the detachable connecting part includes an external thread 106 arranged on the outer cylindrical surface of the air vent tube 104. The surface of the air vent tube 104 is threadedly connected to a threaded cap 301 through the external thread 106. The threaded cap 301 is fixedly sleeved on the upper mouth of the connecting tube 300. Through the setting of the detachable connecting part, the connection and disassembly of the connecting tube 300 and the air vent tube 104 are very convenient, which is convenient for the operation and maintenance of the constant pressure component. The threaded connection method can ensure that the connection between the connecting tube 300 and the air vent tube 104 is firm, prevent loosening or leakage during use, and ensure the safety and reliability of the equipment.

[0031] Preferably, a sealing gasket 105 is embedded on the top of the air tube 104. The provision of the sealing gasket 105 can effectively prevent gas leakage, ensure the sealing between the constant pressure component and the air tube 104, and thus ensure the accuracy and stability of the air pressure balance.

[0032] Working principle;

[0033] When the lead-acid battery body 100 is charged, a small amount of hydrogen will be precipitated at the negative electrode, thereby increasing the air pressure in the lead-acid battery body 100. When the air pressure reaches a certain pressure, the sealing plate 302 is pushed upward, thereby pouring out to the outside through the mouth of the connecting pipe 300, thereby reducing the air pressure in the lead-acid battery body 100. Subsequently, when the air pressure in the lead-acid battery body 100 returns to the standard air pressure, the sealing plate 302 is reset under the influence of the counterweight 306 to seal the mouth of the connecting pipe 300. During the charging process, the chemical reaction occurring inside the lead-acid battery body 100 will release heat. This heat will increase the temperature inside the lead-acid battery body 100 and will also be transferred to the gas generated during charging, so that the gas has a certain temperature. When it is necessary to increase the temperature inside the lead-acid battery body 100 in winter, first remove the cover plate 102 to expose the gas. After the vent tube 104 is fully opened, the vent tube 104 is opened, and the vent tube 104 is opened, and the vent tube 104 is opened, the vent tube 104 is opened, and the vent tube 104 is opened.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
