Description

Technical Field

[0001] This application relates to the field of battery electrolyte filling technology, specifically to a fast filling auxiliary device for silver-zinc battery electrolyte. Background Technology

[0002] Before underwater vehicle testing, the power supply system's battery packs need to be charged. Silver-zinc batteries, as a commonly used battery type, require electrolyte refilling as a crucial step in battery maintenance and preparation. Traditional electrolyte refilling methods have several shortcomings, affecting efficiency and safety.

[0003] Traditional battery electrolyte filling methods have the following problems:

[0004] 1. Traditional glass filling tools have difficulty tightening the rubber stopper, making it hard to create an effective vacuum inside the small battery. This prevents the electrolyte from being injected smoothly into the battery, affecting its performance and lifespan.

[0005] 2. Since the battery pack consists of multiple groups of small batteries, the traditional method of adding them one by one is extremely labor-intensive. Each group of batteries contains 27 small batteries, which need to be added one by one. This is not only time-consuming and labor-intensive, but also increases the workload of the operators.

[0006] 3. There are certain safety hazards in the use of glass filling tools. Because glass is a relatively fragile material, it is prone to breakage during the compaction process, which may cause injury to the operator.

[0007] To address the problems of traditional electrolyte filling methods, improve filling efficiency, reduce workload, and ensure operational safety, it is necessary to design a fast electrolyte filling auxiliary tool for silver-zinc batteries that is safe and reliable to operate, more efficient, reduces workload, and eliminates the risk of injury. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a rapid electrolyte filling auxiliary tool for silver-zinc batteries. By tightening the butterfly nut on the auxiliary tool, the rubber round pad is pressed against the battery filling port. Rotating the handle drives the push rods up and down. Multiple push rods and multiple stainless steel injectors work together to simultaneously perform vacuum extraction and electrolyte filling on multiple battery packs requiring filling. The stainless steel injector shell is made of stainless steel to protect the inner wall of the glass injector. This auxiliary tool enables simultaneous electrolyte filling of multiple small battery packs, reducing the workload of operators. When the rubber round pad is pressed, the stainless steel injector shell bears the force, increasing the safety of the auxiliary tool and effectively preventing personnel injury.

[0009] Specifically, this utility model provides a quick-filling auxiliary tool for silver-zinc battery electrolyte, including: a sliding screw 1, a limiting nut 2, a rotating handle 3, a force-bearing bracket 4, a push rod mounting plate 5, an injector mounting plate 6, a locking butterfly nut 7, a meniscus 8, a meniscus locking nut 9, a rotating threaded rod 10, a rubber round washer 11, an injector head 12, a stainless steel injector 13, a push rod rubber head 14, a push rod 15, a mounting hole 16, a stainless steel injector shell 17, a meniscus base 18, a glass injector inner wall 28, a semi-circular opening 29, and a screw hole 30. The push rod mounting plate 5 has multiple push rods 15 mounted on one side; a meniscus base 18 is fixedly installed on the other side for mounting a rotating threaded rod 10; rotating the rotating threaded rod 10 causes the push rod mounting plate 5 to move up and down, driving the push rod 15 to move up and down; the push rod mounting plate 5 is movably connected to the sliding screw 1; the injector mounting plate 6 is fixedly connected to the sliding screw 1, and multiple stainless steel injectors 13 are mounted on the injector mounting plate 6; rotating the rotating threaded rod 10 causes the push rod 15 to engage with the stainless steel injectors 13, and their coordinated movement completes the vacuum extraction and electrolyte filling within the battery pack; the force-bearing bracket 4 is installed on the rotating threaded rod 10 through a threaded engagement in the middle, and the force-bearing bracket 4 is fixedly connected to the sliding screw 1 for overall structural support.

[0010] Furthermore, one end of the push rod 15 is provided with a thread, and the other end is provided with a push rod rubber head 14 with three layers of rubber, so that it fits tightly against the inner wall of the stainless steel injector 13 to prevent electrolyte reverse osmosis.

[0011] Furthermore, the push rod mounting plate 5 is provided with multiple mounting holes 16, and the mounting holes 16 are provided with internal threads. The threaded end of the push rod 15 is fixedly connected to the mounting hole 16 by the thread. With the thread design, if a single push rod 15 is damaged, it can be replaced individually.

[0012] Furthermore, there are four sliding screws 1, each with a threaded top, which are fixedly connected to the four corners of the force-bearing bracket 4 via threads. Two limiting nuts 2 are installed on the sliding screws 1, one at the top and one at the bottom. Tightening the limiting nuts 2 fixes the force-bearing bracket 4 between the two limiting nuts 2, making the force-bearing bracket 4 more stable. The middle of the sliding screw 1 is a smooth round rod, which facilitates the sliding of the push rod mounting plate 5. The lower end is threaded and fitted with a butterfly nut 7.

[0013] Furthermore, the push rod mounting plate 5 is provided with four circular holes that match the diameter of the sliding screw 1. The push rod mounting plate 5 is fitted onto the sliding screw 1 through the circular holes and is located between the force-bearing bracket 4 and the injector mounting plate 6.

[0014] Furthermore, one end of the injection head 12 is a narrow tip that connects to the battery electrolyte filling port, and the other end is connected to the stainless steel injector housing 17 for electrolyte filling. A rubber round gasket 11 is installed on the injection head 12. Tightening the butterfly nut 7 presses the rubber round gasket 11 against the battery electrolyte filling port, sealing the battery electrolyte filling port. The stainless steel injector housing 17 is made of stainless steel and has a semi-circular opening 29. The upper end has an external thread that connects to the injector mounting plate 6 via the thread. The lower end connects to the injection head 12, and the stainless steel injector housing 17 protects the inner wall 28 of the glass injector. The inner wall 28 of the glass injector is installed inside the stainless steel injector housing 17 and has graduations.

[0015] Furthermore, the semi-circular opening 29 on the stainless steel injector shell 17 corresponds to the scale position set on the inner wall 28 of the glass injector, and the electrolyte filling situation can be observed through the scale.

[0016] Furthermore, the injector mounting plate 6 is fixedly connected to four sliding screws 1, and the injector mounting plate 6 is provided with multiple screw holes 30. The stainless steel injector 13 is fixedly installed on the injector mounting plate 6 through the screw holes 30.

[0017] Furthermore, a meniscus 8 is installed at one end of the rotating threaded rod 10. The meniscus 8 is installed on the meniscus base 18 by the meniscus locking nut 9, so that the rotating threaded rod 10 and the push rod mounting plate 5 are connected through the meniscus 8. Rotating the rotating threaded rod 10 will drive the push rod mounting plate 5 to move, while the push rod mounting plate 5 will not rotate. The rotating threaded rod 10 is provided with an external thread, which is connected to the force-bearing bracket 4. A rotating handle 3 is fixedly installed at the other end of the rotating threaded rod 10. Rotating the rotating handle 3 will drive the rotating threaded rod 10 to rotate synchronously, and at the same time drive the push rod mounting plate 5 and the push rod 15 to move up and down.

[0018] Furthermore, the rotary handle 3 has a knurled surface to prevent the operator from turning the handle.

[0019] Working Principle: When the silver-zinc battery electrolyte rapid filling auxiliary tool is in operation, align the assembled auxiliary tool with the battery pack, ensuring that the filling port of each small battery is accurately aligned with the corresponding part on the auxiliary tool. Tighten the butterfly nut 7 to press the rubber round pad 11 firmly onto the battery filling port, forming a sealed environment. Rotate the rotating handle 3 counterclockwise to drive the rotating threaded rod 10 to rotate. Since the rotating threaded rod 10 is connected to the push rod mounting plate 5 through the meniscus 8, the push rod mounting plate 5 does not rotate when the rotating threaded rod 10 drives the push rod mounting plate 5 to move. The rotation of the rotating threaded rod 10 drives the push rod mounting plate 5 and the push rod 15 to move upward. The push rod rubber head 14 inside the stainless steel injector 13 is tightly attached to the inner wall of the glass injector 24. The upward force of the push rod 15 is transmitted to the push rod rubber head 14. Friction occurs between the rubber head 14 and the inner wall of the glass injector 24, creating a negative pressure environment inside. This draws out the gas inside the battery, creating a vacuum. Since the electrolyte is heavier than air, it will be located in the lower layer inside the glass injector 24, while the drawn-out gas will be located in the upper layer. Rotating the handle 3 clockwise causes the threaded rod 10 to rotate in the opposite direction, pushing the rod mounting plate 5 downward. The rod mounting plate 5 drives the rod 15 downward, and the downward force of the rod 15 is transmitted to the rubber head 14. The rubber head 14 moves downward, thus drawing the electrolyte from the stainless steel injector 13 into the battery. During the filling process, the flow of the electrolyte can be observed through the scale on the inner wall 28 of the glass injector. Once all batteries are filled with electrolyte, the electrolyte filling is complete.

[0020] Beneficial effects:

[0021] 1. This utility model uses multiple push rods and multiple stainless steel liquid injectors to work together, which can complete the electrolyte filling of multiple small batteries at one time, greatly improving the operating efficiency and reducing the time and labor intensity of manual operation.

[0022] 2. This utility model uses a stainless steel injector shell instead of traditional glass to withstand pressure. When the rubber pad is pressed, it effectively prevents the risk of personal injury caused by glass breakage and also increases the tightness between the rubber pad and the battery injection port.

[0023] 3. The push rod rubber head of this utility model adopts a three-layer rubber design, which fits more tightly against the inner wall of the glass injector. This not only improves the sealing effect, but also ensures that no leakage occurs during the extraction or injection of electrolyte, thereby ensuring the accuracy and reliability of the experiment.

[0024] 4. Because the components of this utility model are connected by threads, a single damaged part can be quickly replaced, which reduces maintenance costs and simplifies daily maintenance.

[0025] 5. The shielding plate of this utility model covers the battery measuring column, reducing the exposed area and effectively preventing operators from directly contacting the high-voltage measuring column, thus reducing the risk of electric shock.

[0026] 6. The end of the injection head that connects to the battery electrolyte filling port of this utility model adopts a narrow tip design, which facilitates precise control of the amount of electrolyte added;

[0027] 7. The glass liquid dispenser of this utility model has scale markings on the inner wall, which allows users to clearly know how much liquid has been added, which is conducive to achieving refined management.

[0028] 8. This utility model achieves the fixation and locking of the force-bearing bracket by setting a limit nut and a butterfly nut, thus ensuring the safety of the auxiliary tool during use. Attached Figure Description

[0044] The technical solution will now be described in detail with reference to the accompanying drawings of the embodiments of this utility model.

[0045] Example 1

[0046] like Figure 6 As shown, a quick electrolyte filling accessory for silver-zinc batteries includes: a sliding screw 1, a limiting nut 2, a rotating handle 3, a force-bearing bracket 4, a push rod mounting plate 5, an injector mounting plate 6, a butterfly nut 7, a meniscus 8, a meniscus locking nut 9, a rotating threaded rod 10, a rubber round washer 11, an injection head 12, a stainless steel injector 13, a push rod rubber head 14, a push rod 15, a mounting hole 16, a stainless steel injector housing 17, a meniscus base 18, an electrolyte container 19, a battery pack 20, a battery injection port plug 21, a rubber pad 22, an injection head 23, a glass injector 24, a glass push rod 25, a flathead screwdriver 26, a battery injection port 27, an inner wall of the glass injector 28, a semi-circular opening 29, and a screw hole 30.

[0047] The sliding screw 1, limit nut 2, rotating handle 3, injector mounting plate 6, rotating threaded rod 10, push rod 15, and stainless steel injector housing 17 are all made of stainless steel and have the characteristics of high strength and corrosion resistance.

[0048] like Figure 7As shown, the rotating handle 3 is cross-shaped, and its center is welded to the rotating threaded rod 10. The rotating handle 3 has knurled surfaces, which provides anti-slip function when the handle is rotated. The rotating threaded rod 10 has external threads. The center of the force-bearing bracket 4 is fixedly connected to the rotating threaded rod 10 by threads. The four corners of the force-bearing bracket 4 are respectively connected to the four rotating threaded rods 10 by threads.

[0049] like Figure 6 , 12 As shown in Figures 13 and 14, the rotating threaded rod 10 has four rods, each with a threaded top for mounting limit nuts 2. The sliding screw 1 has two limit nuts 2 mounted on it, one at the top and one at the bottom. Tightening the limit nuts 2 fixes the force-bearing bracket 4 between the two limit nuts 2, making the force-bearing bracket 4 more stable. The middle of the sliding screw 1 is a smooth round rod, which facilitates the sliding of the push rod mounting plate 5. The lower end is threaded and a butterfly nut 7 is mounted on it.

[0050] like Figure 8 As shown, one end of the push rod 15 is threaded, and the other end is equipped with a push rod rubber head 14 with three layers of rubber, so that it fits tightly against the inner wall of the stainless steel injector 13 to prevent electrolyte back osmosis.

[0051] like Figure 11 As shown, the push rod mounting plate 5 has multiple mounting holes 16. Multiple push rods 15 are mounted on one side of the push rod mounting plate 5. The mounting holes 16 are provided with internal threads. The threaded end of the push rod 15 is fixedly connected to the mounting hole 16 through the thread. A meniscus base 18 is fixedly mounted on the other side for mounting a rotating threaded rod 10. A meniscus 8 is mounted on one end of the rotating threaded rod 10. The meniscus 8 is mounted on the meniscus base 18 through the meniscus locking nut 9. After the rotating threaded rod 10 is connected to the push rod mounting plate 5 through the meniscus 8, rotating the rotating threaded rod 10 will drive the push rod mounting plate 5 to move, while the push rod mounting plate 5 will not rotate. The rotating threaded rod 10 is provided with external threads and is connected to the force-bearing bracket 4 through the external threads. A rotating handle 3 is fixedly mounted on the other end of the rotating threaded rod 10. Rotating the rotating handle 3 will drive the rotating threaded rod 10 to rotate synchronously, and at the same time drive the push rod mounting plate 5 and the push rod 15 to move up and down.

[0052] like Figure 11 As shown, the push rod mounting plate 5 is provided with 4 round holes that match the diameter of the sliding screw 1. The push rod mounting plate 5 is fitted onto the sliding screw 1 through the round holes. The push rod mounting plate 5 is located between the force-bearing bracket 4 and the injector mounting plate 6. The injector mounting plate 6 is welded to the 4 sliding screws 1. The injector mounting plate 6 is provided with multiple screw holes 30. The stainless steel injector 13 is fixedly installed on the injector mounting plate 6 through the screw holes 30.

[0053] like Figure 9 ,10 As shown, the stainless steel injector 13 consists of an injector head 12, a stainless steel injector housing 17, and a glass injector inner wall 28. One end of the injector head 12 is a narrow tip that connects to the battery electrolyte filling port, and the other end connects to the stainless steel injector housing 17 for electrolyte filling. A rubber round washer 11 is installed on the injector head 12. Tightening the butterfly nut 7 presses the rubber round washer 11 against the battery electrolyte filling port 27, sealing the battery electrolyte filling port. The stainless steel injector housing 17 is made of stainless steel. It is provided with a semi-circular opening 29, and the upper end is provided with an external thread, which is connected to the liquid injector mounting plate 6 through the thread; the lower end is connected to the liquid injector head 12, and the inner wall 28 of the glass liquid injector is protected by the stainless steel liquid injector shell 17; the inner wall 28 of the glass liquid injector is installed inside the stainless steel liquid injector shell 17, and the inner wall 28 of the glass liquid injector is provided with a scale, and the semi-circular opening 29 on the stainless steel liquid injector shell 17 corresponds to the scale position of the inner wall 28 of the glass liquid injector, so that the electrolyte filling status can be observed through the scale;

[0054] like Figure 12 , 14As shown, during use, first, assemble all components according to the design requirements, rotate the handle 3, and check if the auxiliary tool is operating normally to ensure that all parts are functioning properly. First, open all the battery filling ports 27 on the battery pack 20 using a flathead screwdriver 26; pour all the electrolyte to be added into the electrolyte container 19, and place the assembled auxiliary tool into the electrolyte container 19. Rotate the handle 3, and the push rod mounting plate 5 will drive the push rod 15 upwards, drawing the electrolyte into the stainless steel injector 13. Observe the changes in the electrolyte on the stainless steel injector 13. After reaching the required amount, stop rotating the handle 3 and wait a few seconds to ensure that the electrolyte no longer flows down. Lift the auxiliary tool and move it to the top of the battery pack 20 where electrolyte needs to be added. Align the battery pack 20, ensuring that each battery filling port 27 is accurately aligned with the filling head 12 of the stainless steel filling device 13. Tighten the butterfly nut 7 to press the rubber round pad 11 firmly onto the battery filling port 27, creating a sealed environment. Turn the rotary handle 3 counterclockwise to rotate the rotary threaded rod 10. Since the rotary threaded rod 10 is connected to the push rod mounting plate 5 via the meniscus 8, the push rod mounting plate 5 does not rotate when the rotary threaded rod 10 moves. The rotation of the rotary threaded rod 10 causes the push rod mounting plate 5 and the push rod 15 to move upwards, and the stainless steel filling device 13... The internal push rod rubber head 14 is tightly fitted against the inner wall of the glass injector 24. The upward force of the push rod 15 is transmitted to the push rod rubber head 14, which generates friction with the inner wall of the glass injector 24, creating a negative pressure environment inside. This draws out the gas inside the battery, creating a vacuum. Since the electrolyte is heavier than air, it will be located in the lower layer inside the glass injector 24, while the drawn-out gas will be located in the upper layer. At this time, rotating the handle 3 clockwise causes the threaded rod 10 to rotate in the opposite direction, and the push rod mounting plate 5 moves downward. The push rod mounting plate 5 drives the push rod 15 to move downward. The force is transmitted to the rubber head 14 of the push rod, which moves downward, thereby injecting the electrolyte in the stainless steel injector 13 into the battery. During the filling process, the flow of electrolyte is observed through the scale on the inner wall 28 of the glass injector to ensure that each battery is filled evenly. When all batteries are filled with electrolyte, stop rotating the handle 3 and wait a few seconds to ensure that the electrolyte has completely entered the battery. The electrolyte filling is complete. Loosen the butterfly nut 7, remove the auxiliary tool from the battery pack 20, and use a flathead screwdriver 26 to plug all the battery filling ports 27 and reinstall them. Clean the work area.
