Technical Field

[0001] The utility model relates to the technical field of battery acid addition, in particular to a battery acid addition device that quantitatively uses the drainage method. Background Technique

[0002] One side of the two sides of the battery plate is lead oxide and the other side is pure lead. After adding acid, the electric charges on both sides are unequal and need to be moved and exchanged. Because there is electron movement, there is electricity. When the electric charges are balanced, there is no electricity, and then it is charged. There is a chemical reaction when adding acid, converting chemical energy into electrical energy;

[0003] The structures applied by the current lead-acid battery quantitative acid addition machines on the market are divided into two types. One is to quantitatively add acid solution through a measuring cup and a liquid level sensor, and the other is to control the amount of acid solution by controlling the height of the PVC pipe connected to the acid pumping pump in the measuring cup; the quantitative accuracy of both schemes is not high. Therefore, a liquid level adjustment machine for pumping acid needs to be added after the quantitative acid addition process to make the liquid levels in each battery cell in the lead-acid battery equal, to ensure the consistency of the electrical performance of all batteries, making the overall acid addition process very cumbersome, with extremely low acid addition efficiency, and the existing formic acid structure is complex, prone to failures, and has low reliability; Therefore, we need to propose a battery acid addition device that quantitatively uses the drainage method.

By driving a lead screw with a servo motor to control the height of the quantitative cylinder extending into the measuring cup, the quantitative function of the acid solution inside the measuring cup is realized.

After the quantitative cylinder is filled and overflows, the clamping hole is blocked. At this time, the acid solution inside the measuring cup is the required amount, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A battery acid addition device that quantitatively uses the drainage method, including a quantitative cylinder, a measuring cup, and an acid overflow cylinder.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] The present utility model provides: a battery acid adding device that quantifies by the drainage method, as Figures 1-4 shown, including a measuring cylinder 6, a measuring cup 7 and an acid overflow cylinder 8. The measuring cup 7 is fixedly installed on the inner bottom surface of the acid overflow cylinder 8. The measuring cylinder 6 is slidably arranged inside the measuring cup 7. The bottom surface of the measuring cup 7 is hermetically connected to an acid injection pipeline 9. The bottom surface of the acid overflow cylinder 8 and outside the measuring cup 7 is hermetically connected to an acid return pipeline 13. An acid inlet pipeline 12 is arranged above the measuring cylinder 6. And the inner bottom surface of the measuring cylinder 6 is fixedly connected to a first connecting rod 18. A sealing assembly for controlling the leakage of liquid from the bottom surface of the measuring cylinder 6 is arranged on the inner bottom surface of the measuring cylinder 6. A moving assembly for driving the measuring cylinder 6 to slide up and down is arranged at the top of the first connecting rod 18. The servo motor 1 drives the lead screw 11 to rotate to control the height of the measuring cylinder 6 extending into the measuring cup 7, so as to realize the quantitative function of the acid liquid inside the measuring cup 7. After the measuring cylinder 6 moves to the specified height, the acid inlet pipeline 12 injects the acid liquid inside the acid liquid pool 14 into the measuring cylinder 6, and then flows into the measuring cup 7, filling and overflowing the measuring cylinder 6. The overflowing acid liquid flows into the acid liquid pool 14 through the acid return pipeline 13. Then, the stop valve 10 is opened, and the acid liquid inside the measuring cup 7 flows into the battery cell, thus avoiding the need for subsequent liquid level adjustment procedures and improving the efficiency of the acid adding process with a simple structure.

[0022] The moving component includes a servo motor 1, a motor fixing base 2, a coupling 3, and a lead screw 11. The servo motor 1 is fixedly installed on the upper surface of the motor fixing base 2. The output end of the servo motor 1 penetrates through the motor fixing base 2 and is connected to the coupling 3. The top end of the lead screw 11 is connected to the servo motor 1 through the coupling 3. The servo motor 1 is fixed to the upper part of the motor fixing base 2 to support the servo motor 1, and the servo motor 1 and the lead screw 11 are connected through the coupling 3 to ensure that the lead screw 11 rotates when the servo motor 1 rotates.

[0023] The moving component further includes a lead screw nut fixing base 4 and a lead screw nut 5. The lead screw nut 5 is through-connected and clamped to the top surface of the lead screw nut fixing base 4, and the lead screw 11 threadedly penetrates through the lead screw nut 5. The bottom end of the lead screw 11 is fixedly connected to the top end of the first connecting rod 18. The length of the lead screw nut fixing base 4 is 5 - 10 cm longer than that of the motor fixing base 2, ensuring that when the lead screw nut fixing base 4 is fixed to the wall surface, the motor fixing base 2 will not rub against the wall surface, and the lead screw 11 moves up and down under the action of the lead screw nut 5.

[0024] The sealing component includes a sealing clamping ring 15, an electric push rod 16, and a second connecting rod 19. The electric push rod 16 is fixedly installed on the bottom surface of the lead screw nut fixing base 4. The top end of the second connecting rod 19 is fixedly connected to the bottom surface of the electric push rod 16. The sealing clamping ring 15 is fixedly installed at the bottom end of the second connecting rod 19. The top surface of the electric push rod 16 is bolted to the bottom surface of the lead screw nut fixing base 4. When the electric push rod 16 is started, it drives the second connecting rod 19 to move up and down, thereby driving the sealing clamping ring 15 to move up and down inside the metering cylinder 6.

[0025] An acid storage tank 14 is fixedly arranged on the side of the acid injection pipe 9. A sealing clamping ring 15 is arranged inside the acid storage tank 14. The bottom surface of the acid inlet pipe 12 is hermetically connected to the top end of the sealing clamping ring 15, and the acid storage tank 14 is located at the bottom of the acid return pipe 13. The sealing clamping ring 15 conveys the acid inside the acid storage tank 14 to the acid inlet pipe 12, and then inputs it into the metering cylinder 6 through the acid inlet pipe 12. The inner diameter of the overflow acid cylinder 8 is 5 - 10 cm larger than the outer diameter of the measuring cup 7, so as to ensure that the acid overflowing from the metering cylinder 6 can enter the overflow acid cylinder 8, and then the overflowing acid flows back into the acid storage tank 14 through the acid return pipe 13.

[0026] A stop valve 10 is hermetically arranged on the side of the acid injection pipe 9, and the bottom surface of the acid injection pipe 9 is connected to the storage battery. When the measuring cup 7 is filled with acid, the stop valve 10 is opened, and the acid can flow into the storage battery trough through the acid injection pipe 9.

[0027] The outer diameter of the metering cylinder 6 is the same as the inner diameter of the measuring cup 7, and a clamping hole 17 corresponding to the sealing clamping ring 15 is formed through the bottom surface of the metering cylinder 6. When the acid solution inside the metering cylinder 6 is filled and overflows, the electric push rod 16 pushes the sealing clamping ring 15 to seal and block the clamping hole 17. At this time, the acid solution inside the measuring cup 7 is the required amount, and the outer diameter of the metering cylinder 6 is the same as the inner diameter of the measuring cup 7, so as to ensure that the acid solution can only enter the inside of the measuring cup 7 through the clamping hole 17 at the bottom end of the metering cylinder 6, and avoid excessive acid solution from flowing into the acid injection pipe 9 through the inner wall of the measuring cup 7 after the clamping hole 17 is sealed and blocked.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
