Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, and in particular to a lead-acid battery cover pressure strip structure for quantitative acid addition. Background Technology

[0002] A lead-acid battery is a type of rechargeable battery whose electrodes are primarily made of lead and its oxides, and whose electrolyte is a sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead; in the charged state, both the positive and negative electrodes are mainly composed of lead sulfate.

[0003] With the rapid development and evolution of the new energy market, the market demand for network energy batteries, as a core component, is experiencing explosive growth. As the price of raw materials for lead-acid batteries rises, competition in the lead-acid battery market is becoming increasingly fierce. Lead-acid battery manufacturers must continuously reduce production costs and shorten battery production cycles to enhance their overall competitiveness. Currently, in the manufacturing process of network energy batteries, manufacturers use an over-acid internal formation method for acid addition and charging formation. After charging formation, depending on the environment, equipment, and battery usage scenario, online acid extraction or acid extraction within a specified time after settling is performed. With equipment upgrades and site replanning, the traditional over-acid addition method for network energy batteries (online acid extraction after formation) or (acid extraction within a specified time after settling) occupies equipment or space, adding an extra step and increasing manpower. Furthermore, the waste acid from extraction requires treatment, increasing environmental costs. It also cannot guarantee battery safety and disassembly / reassembly efficiency. Therefore, we propose a quantitative acid addition battery cover pressure strip structure for lead-acid batteries. Utility Model Content

[0027] Example

[0028] like Figures 1-5 As shown, this embodiment provides a lead-acid battery cover pressure strip structure for quantitative acid addition, including a battery cover body 1, and multiple sets of valve seat ports 2 on the top of the battery cover body 1. The multiple sets of valve seat ports 2 are linearly distributed on the top of the battery cover body 1, and a rubber cap valve 3 is installed on the top of the valve seat port 2. A pressing strip 4 is provided on the top of the valve seat port 2, and two sets of engaging grooves 5 are opened on the outer side of the wall of the valve seat port 2. The two sets of engaging grooves 5 are symmetrically distributed on the outer side of the wall of the valve seat port 2. Two sets of engaging posts 6 are connected through the top of the pressing strip 4. 6 are symmetrically distributed on the top of the pressing strip 4. The top of the locking post 6 is provided with a sealing top plate 7. The top of the inner wall of the two sets of locking grooves 5 is provided with locking holes 9. The outer wall of the locking post 6 is provided with multiple sets of limiting protrusions 13, which are arranged in a ring on the outer wall of the locking post 6. The inner wall of the locking hole 9 is provided with multiple sets of limiting sliding grooves 14, which are arranged in a ring on the inner wall of the locking hole 9. The inner wall of the locking hole 9 is provided with multiple sets of deflection locking grooves 15, which are arranged in a ring on the inner wall of the locking hole 9.

[0029] Among them, the multiple sets of valve seat ports 2 are the acid injection positions of the battery cover body 1, and play a key role in sealing the battery, venting water vapor, preventing electrolyte leakage, and protecting battery safety through the rubber cap valve 3, ensuring the normal operation of the battery and extending its service life; the pressing strip 4 can press and protect the valve seat ports 2 and the rubber cap valve 3. This component achieves pressing installation through the insertion of the locking post 6 and the locking hole 9, and the limiting locking of multiple sets of limiting protrusions 13 and the limiting slide groove 14 bottom deflection groove 15; the sealing top plate 7 can limit the locking post 6 to ensure the pressing effect of the pressing strip 4.

[0030] A lifting ring 8 is fixedly connected to the top of the sealing top plate 7.

[0031] The lifting ring 8 is designed to facilitate lifting and rotating the locking column 6, thereby facilitating the locking and installation of the pressure strip 4.

[0032] The bottom end of the engagement hole 9 is provided with a retraction cavity 10, and a compression spring 11 is installed inside the retraction cavity 10. The top end of the compression spring 11 is fixedly connected to a spring plate 12.

[0033] The retraction cavity 10 provides a space for the compression spring 11 and the spring plate 12, and the spring force of the compression spring 11 is applied to the locking post 6 through the spring plate 12, thereby improving the locking tightness of the locking post 6 and further improving the installation and pressing effect of the pressing strip 4.

[0034] The bottom end of the limiting groove 14 is connected to the deflection slot 15.

[0035] The connection between the limiting groove 14 and the deflection slot 15 allows the limiting protrusion 13 to smoothly deflect from the limiting groove 14 into the deflection slot 15, thereby improving installation efficiency.

[0036] Two sets of sealing rings 16 are installed on the top of the pressing strip 4, and the two sets of sealing rings 16 are symmetrically distributed on the top of the pressing strip 4.

[0037] Among them, the two sets of sealing rings 16 are set so that they can make close contact with the bottom end of the sealing top plate 7 after the locking column 6 is pressed, thereby achieving a seal and preventing acid from contaminating and damaging the internal components of the locking structure during the acid addition process.

[0038] A magnetic ring 17 is fitted into the top of the sealing ring 16, and a fitting groove 18 is provided at the bottom of the sealing top plate 7. A metal ring 19 is installed inside the fitting groove 18.

[0039] The use of the magnetic ring 17 allows it to be attracted to the metal ring 19 in the fitting groove 18 of the sealing top plate 7, thereby ensuring the installation effect while avoiding accidental contact.

[0040] A lifting block 20 is fixedly connected to the top of the pressing strip 4.

[0041] The lifting block 20 makes it easy for users to lift the entire pressing strip 4, further facilitating subsequent acid disassembly operations.

[0042] Working principle:

[0043] During installation, the user aligns the pressure strip 4 with the two sets of engagement grooves 5 on the outer side of the valve seat 2 and inserts it. Then, the user aligns the multiple sets of limiting protrusions 13 on the outer side of the engagement post 6 with the limiting grooves 14 on the inner wall of the engagement hole 9 and presses them in. The engagement post 6 moves along the limiting grooves 14 into the engagement hole 9 and presses against the return plate 12 and compression spring 11 at the bottom of the valve. The rebound force generated by the deformation of the compression spring 11 is applied to the engagement post 6 until it can no longer move down, i.e., the limiting protrusions 13 contact the bottom of the limiting grooves 14. At this point, the user deflects the engagement post 6 using the lifting ring 8, causing the limiting... The protrusion 13 is inserted into the deflection slot 15. The deflection slot 15 restricts the movement of the engagement post 6 into the engagement hole 9, and the pressing strip 4 is installed. When the engagement is complete, the metal ring 19 at the bottom of the sealing plate 7 at the top of the engagement post 6 will contact the magnetic ring 17 on the sealing ring 16, thereby further limiting the engagement post 6 through magnetic attraction. Thus, the excessive acid addition to the battery can be reduced by the tight fit between the valve seat port 2 and the pressing strip 4, and the use of the rubber cap valve 3, so as to make full use of the equipment.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
