Description

Technical Field

[0001] This utility model belongs to the field of zinc-silver reserve battery technology, and in particular relates to a device for simulating the electro-hydraulic distribution of a zinc-silver reserve battery. Background Technology

[0002] Zinc-silver batteries are characterized by high energy density, stable discharge voltage, and high safety and reliability. Currently, deep-sea submersibles and decoy torpedoes internationally widely use zinc-silver reserve batteries as their power source. During the manufacturing of zinc-silver reserve batteries, electrolyte needs to be injected into the individual cells of the battery pack. If the electrolyte distribution in individual cells is uneven, the battery pack with lower capacity will frequently be in a deep charge and discharge state during use, resulting in faster capacity decay. Since the performance of the battery pack is controlled by the lower-capacity individual cells, uneven capacity distribution in individual cells can cause battery pack failure. Therefore, simulation experiments are necessary to ensure uniform electrolyte distribution within individual cells.

[0003] Existing devices for simulating electrolyte distribution in zinc-silver reserve batteries typically employ a fixed structure where multiple individual battery cells are connected to distribution tubes. Since the distribution tubes and individual battery cells are not detachable, a completely new simulation device must be fabricated when simulating electrolyte distribution under different distribution tube conditions, resulting in a waste of materials and time and hindering cost savings. Furthermore, existing simulation devices do not consider the impact of reverse pressure within each battery cell on the uniformity of electrolyte distribution. Therefore, the electrolyte filling volume within a single battery cell determined through simulation experiments is inaccurate and cannot be used as a basis for designing real battery packs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for simulating the electrolyte distribution of a zinc-silver reserve battery. Different electrolyte distribution tubes can be replaced according to the test requirements, which reduces the waste of materials and labor time and lowers the test cost.

[0005] The technical solution adopted in this utility model is:

[0006] An apparatus for simulating electro-hydraulic distribution in a zinc-silver reserve battery includes a simulated battery assembly and a liquid injection distribution tube; the simulated battery assembly includes end plates disposed opposite each other, a plurality of individual cells disposed side by side between the two end plates, and a locking member for connecting and fastening the end plates and the individual cells; the liquid injection distribution tube is detachably inserted through the end plates and the individual cells.

[0007] Furthermore, the single battery cell includes a chamber and a connecting portion surrounding the chamber. The connecting portion is provided with a connecting hole that penetrates the thickness of the single battery cell and is adapted to the locking member. The end plate is provided with a corresponding connecting hole.

[0008] Furthermore, the chamber is provided with a distribution hole that penetrates the thickness of the single cell and is adapted to the liquid injection distribution tube, and the distribution hole is provided with an injection port; the end plate is provided with a corresponding distribution hole.

[0009] Furthermore, the liquid injection distribution pipe includes a distribution pipe connector, a distribution channel, and a pressure sensor connector; the distribution pipe connector is used to connect to the liquid storage tank; the distribution channel is provided with an injection hole adapted to the liquid injection port; the pressure sensor connector is used to connect to a pressure sensor to obtain the pressure value in the distribution channel when electro-hydraulic distribution is performed using the liquid injection distribution pipe.

[0010] Furthermore, the cavity is filled with a filler, the volume of which can be selectively set.

[0011] Furthermore, the pressure sensor connector is snapped onto the outside of the end plate, and the distribution pipe connector passes through the distribution hole and is fixed to the outside of another end plate by fasteners; both are provided with sealing rings between themselves and the end plates.

[0012] Furthermore, an annular groove and a partition plate are respectively provided on the connection surface of adjacent individual cells. The annular groove is arranged around the cavity in the connection part, and a sealing element is provided in the annular groove.

[0013] Furthermore, the inner side of the end plate is provided with the annular groove, and the sealing element is provided in the annular groove.

[0014] Furthermore, the locking elements are evenly distributed around the annular groove.

[0015] Furthermore, at least the chamber portion of the single-cell battery is made of a transparent material.

[0016] The advantages and positive effects of this utility model are:

[0017] (1) By designing the liquid injection distribution to be detachably inserted into the simulated battery assembly, different liquid injection distribution tubes can be replaced according to the test requirements. The same device can be used to examine the electro-hydraulic distribution using different liquid injection distribution tubes to meet the test requirements of different liquid injection distribution tubes; this reduces the waste of materials and time and lowers the test cost.

[0018] (2) By setting a filler in the cavity of a single cell, the volume of the filler is calculated by the reverse pressure theory. The volume of the cavity can be adjusted so that the instantaneous internal pressure in the cavity is maintained at the set value, thereby meeting the ratio requirement between the external pressure and the instantaneous internal pressure. This truly restores the electro-hydraulic distribution of the battery pack, which not only significantly improves the uniformity of electro-hydraulic distribution, but also makes the cavity volume determined by the simulation test more accurate, providing a reliable basis for the design of the cavity volume of a single cell in the battery pack.

[0019] (3) By setting annular grooves, sealing elements and separators, the individual cells and end plates are tightly fitted together, forming a tight sealing structure, which can effectively prevent gas or liquid from flowing out from the connection surface of adjacent individual cells, thus ensuring the accuracy of the simulation test results.

[0027] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0028] This utility model provides a device for simulating the electrolyte distribution of a zinc-silver reserve battery, used for conducting electrolyte distribution simulation tests. The individual cells that make up the simulated battery pack are detachably connected to the electrolyte distribution tubes, allowing the same simulated battery pack to be used to test the distribution effect of different electrolyte distribution tubes as needed, without having to remake the entire simulation device, reducing the waste of materials and time, and lowering the test cost.

[0029] like Figure 1 , Figure 2 As shown in the figure, this application provides a device for simulating the electro-hydraulic distribution of a zinc-silver reserve battery, including a simulated battery assembly and an injection distribution tube; the simulated battery assembly includes an end plate 1 disposed opposite to each other, a plurality of individual cells 2 disposed side by side between the two end plates 1, and a locking member 6 for connecting and fastening the end plate 1 and the individual cells 2; the injection distribution tube is detachably inserted through the end plate 1 and the individual cells 2.

[0030] In this embodiment, the individual battery 2 is made based on the actual zinc-silver reserve battery individual battery 2, and has a set thickness. Several individual batteries 2 are arranged side by side along the thickness direction. Two end plates 1 are arranged opposite each other on both sides of several individual batteries 2. The locking member 6 is used to connect the individual battery 2 and the end plate 1 as a whole, and to make adjacent individual batteries 2 and individual batteries 2 and end plates 1 fit tightly together, ensuring that the overall structure is connected stably. The liquid injection distribution tube is used to inject electrolyte into the individual battery 2. By detachably inserting it through the end plate 1 and the individual battery 2, it can be ensured that it can contact each individual battery 2, and at the same time, it is convenient to replace different liquid injection distribution tubes according to the test requirements to meet the test requirements of different liquid injection distribution tubes.

[0031] In this embodiment, the single battery cell 2 includes a chamber 21 and a connecting portion surrounding the chamber 21. The connecting portion has a connecting hole that penetrates the thickness of the single battery cell 2 and is adapted to the locking member 6. The end plate 1 has a corresponding connecting hole. The chamber 21 is used to contain electro-hydraulic fluid and is located in the middle of the single battery cell 2. The connecting portion is located around the chamber 21. For example, the connecting portion is a solid structure, which is arranged and connected together along the four directions of up, down, left, and right to form a rectangular chamber 21. The two sides of the chamber 21 are closed by the shell. By providing connecting holes in the connecting portion and corresponding connecting holes at the end, the locking member 6 can pass through the end plate 1, several battery cells, and the other end plate 1 in sequence to connect the end plate 1 and the single battery cell 2 together.

[0032] In one specific embodiment, both the individual battery 2 and the end plate 1 are rectangles of the same size and shape. The locking member 6 is arranged along the four sides of the rectangle. After the locking member 6 passes vertically through the end plate 1 and several individual batteries 2, both ends are fixed to the end plate 1 by fasteners 10. The two ends of the locking member 6 are threaded, and the fasteners 10 are threaded to the locking member 6. The locking member 6 can be fixed to the end plate 1 by tightening the fasteners 10. Through the above technical solution, the individual battery 2 and the end plate 1 can be quickly and conveniently assembled. The clamping degree of the end plate 1 on the battery cell can also be adjusted by the fasteners 10 to ensure that adjacent individual batteries 2 and the individual battery 2 and the end plate 1 are tightly fitted to meet the requirements of simulation test.

[0033] In the above embodiment, the thickness of the end plate 1 is greater than the thickness of the single cell 2 to ensure that the end plate 1 has sufficient rigidity and will not deform under the pressure of the fastener 10, and to provide sufficient clamping force to the single cell 2. Preferably, the fastener 10 is a nut, and a washer 7 is provided between the fastener 10 and the end plate 1 to enhance the stability of the connection.

[0034] In this embodiment, the chamber 21 is provided with a distribution hole that penetrates the thickness of the single cell 2 and is adapted to the liquid injection distribution pipe, and a liquid injection port is provided in the distribution hole; the end plate 1 is provided with a corresponding distribution hole. The circumferential distribution hole is provided with an inner wall that connects to the shell of the chamber 21 to seal the chamber 21; the liquid injection port is set at a predetermined position on the inner wall, and the distribution hole communicates with the interior of the chamber 21 through the liquid injection port; when the liquid injection distribution pipe passes through the distribution hole and is fixed to the simulated battery assembly, the electrolyte can flow from the liquid injection distribution pipe through the liquid injection port into the chamber 21.

[0035] In the embodiments of this application, such as Figure 3 As shown, the liquid injection distribution pipe includes a distribution pipe connector 81, a distribution channel 82, and a pressure sensor connector 83. The distribution pipe connector 81 is used to connect to the liquid storage tank. The distribution channel 82 is provided with a liquid injection hole adapted to the liquid injection port. The pressure sensor connector 83 is used to connect to a pressure sensor to obtain the reverse pressure value when the liquid injection distribution pipe is used for electro-hydraulic distribution. The above-mentioned liquid storage tank contains electro-hydraulic fluid and can be detachably connected to the distribution pipe connector 81. The distribution pipe connector 81 and the distribution channel 82 are provided with a communicating electro-hydraulic flow channel. The liquid injection hole is opened on the surface of the distribution channel 82 and communicates with the electro-hydraulic flow channel. The position and number of the liquid injection hole are adapted to the position and number of the liquid injection port of the single cell 2. When the distribution pipe connector 81 is connected to the liquid storage tank, the electro-hydraulic fluid can flow through the electro-hydraulic flow channel to the liquid injection hole, and then through the liquid injection hole to the liquid injection port, and then through the liquid injection port into the chamber 21 to realize the distribution of electro-hydraulic fluid. The pressure sensor connector 83 is detachably connected to the pressure sensor, which can accurately obtain the real-time pressure in the electro-hydraulic flow channel when electro-hydraulic distribution is performed in the injection distribution tube, so as to ensure that the electro-hydraulic distribution is carried out at the set pressure.

[0036] It should be noted that during the electro-hydraulic distribution process, the individual battery 2 is subjected to both external and internal pressures. The external pressure, i.e., the pressure within the electro-hydraulic flow channel, can be obtained by a pressure sensor in this embodiment, and its magnitude mainly depends on the activation pressure applied by an external force, such as the amount of gas supplied by a gas generator or gas cylinder. The internal pressure is the instantaneous internal pressure of the cavity during activation, which is a design empirical value and depends on the volume of the cavity 21 within the individual battery 2. In the prior art, the influence of the instantaneous internal pressure on the uniformity of electro-hydraulic distribution was not considered when conducting electro-hydraulic distribution simulation experiments. However, the inventors of this application have discovered that when the ratio between the external pressure and the instantaneous internal pressure is at a set value, the uniformity of electro-hydraulic distribution can be significantly improved. Therefore, by setting a pressure sensor connector 83 and connecting a pressure sensor, the pressure within the electro-hydraulic flow channel can be detected in real time, thereby controlling the ratio between the external pressure and the instantaneous internal pressure during the electro-hydraulic distribution process to improve the uniformity of electro-hydraulic distribution.

[0037] In this application, the ratio between external pressure and instantaneous internal pressure is a set range value. The inventors of this application have discovered that, under normal circumstances, the flow rate of each individual cell 2 corresponding to the downstream end of the liquid injection distribution tube is different from that of each individual cell 2 at the upstream end, and the flow rate difference between each individual cell 2 is large, which leads to uneven electrolyte volume in the individual cell 2. By adjusting the instantaneous internal pressure of different individual cells 2, the phenomenon of different flow rates at the liquid injection ports of each individual cell can be improved, effectively solving the problem of uneven electrolyte distribution.

[0038] Furthermore, in the above embodiment, the chamber 21 is filled with a filler, the volume of which can be selectively set. Specifically, the volume of the filler is calculated using the reverse pressure theory. Under a constant external pressure, by setting different volumes of filler in the chamber 21, the cavity volume within the chamber 21 can be adjusted, maintaining the instantaneous internal pressure within the chamber 21 at a set value, thereby satisfying the ratio requirement between the external pressure and the instantaneous internal pressure. Through the above technical solution, the electrolyte distribution of the battery pack can be realistically reproduced, significantly improving the uniformity of electrolyte distribution and making the cavity volume of the chamber 21 determined through simulation experiments more accurate, providing a reliable basis for the design of the volume of the chamber 21 of the individual battery cells in the battery pack.

[0039] In one specific embodiment, the filling material is a filling plate with a certain thickness and its shape and size are adapted to the chamber 21. By filling the chamber 21 with different numbers of filling plates, the space occupied by the filling plates can be adjusted, thereby adjusting the cavity volume of the chamber 21 to match different instantaneous internal pressure requirements.

[0040] It is understandable that different models of single-cell batteries 2 have different cavity volumes 21. Through the above technical solution, the electro-hydraulic distribution of different models of single-cell batteries 2 can be simulated by setting the volume of the filling material, thus expanding the applicability of the device.

[0041] The pressure sensor connector 83 is snapped onto the outside of the end plate 1, and the distribution pipe connector 81 passes through the distribution hole and is fixed to the outside of another end plate 1 by a fastener 10; both are provided with sealing rings 9 between themselves and the end plate 1. Specifically, the shape of the pressure sensor connector 83 is larger than the distribution hole, and the shapes of the distribution pipe connector 81 and the distribution channel 82 are adapted to the distribution hole, allowing them to freely pass into the distribution hole. The length of the distribution channel 82 is adapted to the distance between the two end plates 1, so that the distribution pipe connector 81 after passing through the end plate 1 is located outside the end plate 1; the distribution pipe connector 81 is equipped with a dedicated fastener 10, which can be used to fix it to the outside of the end plate 1; by setting the sealing ring 9, not only can the connection between the electro-hydraulic distribution pipe 8 and the end plate 1 be sealed, but the stability of the connection between the distribution pipe connector 81 and the pressure sensor connector 83 and the end plate 1 can also be enhanced.

[0042] In one specific embodiment, a fastening groove is provided on the connection surface between the pressure sensor connector 83 and the end plate 1, and a sealing ring 9 is embedded in the fastening groove; another sealing ring 9 is sleeved on the connection part between the distribution pipe connector 81 and the distribution channel 82, located between the distribution pipe connector 81 and the end plate 1.

[0043] Furthermore, in the embodiments of this application, such as Figure 2 , Figure 4 As shown, to ensure the stability of external pressure and instantaneous internal pressure and prevent electrolytic leakage, annular grooves 4 and partition plates 3 are respectively provided on the connection surfaces of adjacent single-cell batteries 2. The annular grooves 4 are arranged around the cavity 21 at the connection part, and a sealing element 5 is provided inside the annular grooves 4. Specifically, the sealing element 5 is embedded in the annular groove 4, closely fitting with the annular groove 4 and arranged around the annular groove 4. The cross-sectional dimensions of the sealing element 5 are adapted to the annular groove 4. At least part of the sealing element 5 protrudes from the annular groove 4 when not under pressure, and deforms and shrinks into the annular groove 4 after being squeezed by the partition plate 3, so as to achieve a tight fit between the annular groove 4, the sealing element 5 and the partition plate 3, forming a tight sealing structure, which can effectively prevent gas or liquid from flowing out from the connection surface of adjacent single-cell batteries 2, ensuring the accuracy of the simulation test results.

[0044] Specifically, the seal 5 has sufficient tensile strength and hardness to withstand the working pressure during simulated experiments; it also has good elastic recovery ability, allowing the single cell 2 to be repeatedly assembled and used, ensuring a good sealing effect.

[0045] In the above embodiments, the sealing element 5 can be an O-ring or other types of sealing element 5, as long as it can cooperate with the annular groove 4 and the partition plate 3.

[0046] It should be noted that the single cell 2 includes single cells 2 located at both ends and attached to the end plates 1, and single cells 2 located in the middle that are adjacent to each other. For the single cell 2 in the middle, the annular groove 4 and the separator 3 are disposed opposite each other on two sides in the thickness direction of the single cell 2. The separator 3 is embedded in the single cell 2 and can be made of a material that is easier to cooperate with the sealing element 5 to improve the sealing effect. For the single cells 2 located at both ends and attached to the end plates 1, only the annular groove 4 or the separator 3 can be provided as needed.

[0047] Furthermore, in this embodiment, the inner side of the end plate 1 is also provided with an annular groove 4, and a sealing element 5 is also provided in the annular groove 4; preferably, the position of the annular groove 4 on the end plate 1 corresponds to the position of the annular groove 4 on the single cell 2, and both are set close to the cavity 21 to achieve a good sealing effect; the single cell 2 connected to one of the end plates 1 has an annular groove 4 and a sealing element 5 on the side away from the end plate 1, and the side close to the end plate 1 is directly pressed and connected to the sealing element 5 on the end plate 1; the single cell 2 connected to the other end plate 1 has a partition plate 3 on the side away from the end plate 1, and the side close to the end plate 1 is directly pressed and connected to the sealing element 5 on the end plate 1; through this setting, a sealed connection is formed between adjacent end plates 1 and single cells 2, and between adjacent single cells 2, which can achieve a good sealing effect.

[0048] Furthermore, in this embodiment, the locking member 6 is evenly distributed around the annular groove 4. The locking member 6 is disposed on the outside of the annular groove 4 to avoid affecting the sealing effect of the sealant 5; at the same time, by evenly distributing the locking member 6, the force on different parts of the end plate 1 and the single battery cell 2 can be more even, and the connection can be more stable.

[0049] In one specific embodiment, the connection surfaces of the end plate 1 and the single cell 2 are both rectangular, the chamber 21 is a cuboid structure, and the annular groove 4 is also designed as a rectangle surrounding the chamber 21 and at a distance set from the chamber 2; the locking member 6 is evenly arranged around the annular groove 4.

[0050] Furthermore, at least the chamber 21 of the single cell 2 is made of transparent material, allowing testers to easily observe the electrolyte distribution from the outside and measure the amount of electrolyte distributed in the chamber 21. By subtracting the volume of the filling material from the volume of the chamber 21, the accurate amount of electrolyte distributed in each single cell 2 can be obtained.

[0051] In one specific embodiment, the end plate 1 closest to the distribution pipe connector 81 is designated as the rear end plate 1, and the other end plate 1 is designated as the front end plate 1. When assembling the device simulating the electrolyte distribution of a zinc-silver reserve battery, the rear end plate 1 is first placed on a horizontal surface. Sealant is applied to the annular groove 4 of the rear end plate 1, followed by embedding the sealing element 5 into the annular groove 4. Then, locking elements 6 are sequentially inserted into the connection holes of the rear end plate 1. The locking elements 6 are fixed to the rear end plate 1 by washers 7 and fasteners 10. Similarly, each individual battery 2 has a sealing element 5 bonded to its annular groove 4 with sealant and filled with filler material. Then, each individual battery 2 is passed through the connection hole and then through the locking elements 6, so that the lower... A separator plate 3 of a single cell 2 presses against the seal 5 of another single cell 2. After all single cells 2 are installed, the front end plate 1 is installed. Then, the electro-hydraulic distribution pipe 8 is inserted into the front end plate 1, the single cell 2, and the rear end plate 1 through the distribution hole. The locking member 6 is locked with the washer 7 and the fastener 10, and the electro-hydraulic distribution pipe 8 is locked with the fastener 10 and the sealing ring 9. In use, the distribution pipe connector 81 of the electro-hydraulic distribution pipe 8 is connected to the storage tank, and the pressure sensor connector 83 is connected to the pressure sensor. Under external pressure, the electro-hydraulic fluid breaks through the rupture membrane of the storage tank and flows through the electro-hydraulic flow channel to the injection hole and the chamber 21 of the single cell 2, completing the simulated electro-hydraulic distribution. Subsequently, the electro-hydraulic height in the chamber 21 of each single cell 2 is measured with a measuring instrument. By subtracting the corresponding volume of the filler, the electro-hydraulic distribution amount in each chamber 21 can be calculated, thereby effectively evaluating the effect of simulated electro-hydraulic distribution. After the simulated electro-hydraulic distribution is completed, remove the reservoir and place the device upside down. Connect a vacuum device to the distribution pipe connector 81 of the electro-hydraulic distribution pipe 8 to extract all the electro-hydraulic solution from the device. Then, straighten the device, and it is ready for the next test. When it is necessary to investigate the effect of different injection hole sizes on electro-hydraulic distribution, only the injection distribution pipe needs to be replaced; there is no need to disassemble the entire device.

[0052] The advantages and positive effects of this utility model are:

[0053] (1) By designing the liquid injection distribution to be detachably inserted into the simulated battery assembly, it is easy to replace different liquid injection distribution tubes according to the test requirements. The same device can be used to examine the electro-hydraulic distribution using different liquid injection distribution tubes to meet the test requirements of different liquid injection distribution tubes; this reduces the waste of materials and time and lowers the test cost.

[0054] (2) By setting a filler in the cavity of a single cell, the volume of the filler is calculated by the reverse pressure theory. The volume of the cavity can be adjusted so that the instantaneous internal pressure in the cavity is maintained at the set value, thereby meeting the ratio requirement between the external pressure and the instantaneous internal pressure. This truly restores the electro-hydraulic distribution of the battery pack, which not only significantly improves the uniformity of electro-hydraulic distribution, but also makes the cavity volume determined by the simulation test more accurate, providing a reliable basis for the design of the cavity volume of a single cell in the battery pack.

[0055] (3) By setting annular grooves, sealing elements and separators, the individual cells and end plates are tightly fitted together, forming a tight sealing structure, which can effectively prevent gas or liquid from flowing out from the connection surface of adjacent individual cells, thus ensuring the accuracy of the simulation test results.

[0056] (4) The overall structure is exquisite and concise, simple in structure, easy to process, easy to install and disassemble, and easy to use.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
