Description

Technical Field

[0001] The utility model belongs to the technical field of storage batteries, and in particular relates to a lead-acid storage battery (EVF battery) for low-speed electric vehicles, which is a formation tank array with adjustable overflow port height and an overflow port height adjustment device. Background Art

[0002] Lead-acid batteries are widely used in industries such as industry and transportation. Lead-acid batteries for low-speed electric vehicles (EVF batteries) are a type of lead-acid batteries. Lead-acid batteries for low-speed electric vehicles (EVF batteries) need to be formed during the production process. The battery formation process is an important process in the production of lead-acid batteries. Because the battery formation process generates heat, circulating water is required to cool the battery in order to control the electrolyte temperature during the formation process. The formation process usually uses a formation tank array to cool the outside of the battery with water. The control of the water temperature in the tank during the formation process of the battery plays a vital role in affecting the quality of the battery.

[0003] A formation tank array is usually provided with a water inlet and an overflow port. The water inlet is used to introduce low-temperature cooling water into the tank body, and the overflow port is used to discharge high-temperature water in the tank body to adjust the water temperature in the tank. In the actual production process, the water temperature in the formation tank is actually lower the closer to the bottom of the tank, and higher the closer to the water surface. In order to achieve the best temperature regulation effect, the existing formation tank array sets the water inlet at the bottom of the tank body and sets multiple overflow ports side by side near the water surface.

[0004] However, at present, the overflow holes of most formation tanks are fixed in height. Since the formation tanks are placed on the ground, if the ground sinks (not level) or the tank itself deforms during use (since the tank is very long, the bottom support is like a bridge pier, which is spaced apart. After long-term use, deformation will occur), the water level heights at different positions in the tank will be different. In this way, some overflow holes will drain water during the formation process, while some overflow holes will not drain water. In the parts where water cannot be drained, the circulating water has poor flow effect and cannot take away the heat generated by the battery formation process in time; in the parts with good drainage effect, the circulating water has good flow effect and can take away the heat generated by the battery formation process in time. As a result, the electrolyte temperature of some batteries in the formation process is normal, while the electrolyte temperature of some batteries in the formation process exceeds the standard requirements. The formation consistency is poor and the battery performance consistency is poor. Since lead-acid batteries (EVF batteries) for low-speed electric vehicles are used in groups, the battery performance consistency is poor, which will affect the use effect of the entire group, the battery life ends prematurely, and affect customer use. Summary of the invention

[0005] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art, thereby providing a formation tank array with adjustable overflow port height and an overflow port height adjustment device, by adjusting the height of the overflow hole, ensuring that the discharge volume of circulating water at different positions of the tank array is consistent, thereby ensuring the heat dissipation effect.
