Description

Technical Field

[0001] The present application relates to the technical field of liquid flow battery testing, and in particular to a device for testing a liquid flow battery. Background Art

[0002] At present, liquid flow batteries are composed of point stack units, electrolytes, electrolyte storage and supply units, and management and control units. They are high-performance batteries that separate the positive and negative electrolytes and circulate them separately. They have the characteristics of high capacity, wide application range, and long cycle life. They are a new energy product.

[0003] There are many tests for flow batteries during their development, such as cycle performance tests, electrolyte physical property tests, and stack pressure tests, etc., to characterize the various performances of flow batteries during use. In the prior art, the test conditions usually use a device to place the test stack at a high place, and then place the electrolyte storage tank at a low place, and connect them through a circulation pipeline. This method is relatively simple. For example, when testing the operating performance of the flow battery and the electrolyte storage tank at different relative heights, the height can only be adjusted by pads, which is very unsafe and inconvenient. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of the present application is to provide a device for testing a flow battery, which can provide a testing platform conveniently, quickly and safely.

[0005] In order to achieve the above objectives, on the one hand, the technical solutions adopted are:

[0006] The present application provides a device for testing a flow battery, comprising a base, a facade frame, an angle adjustment column, a sliding member and a supporting device;

[0007] The sliding member is slidably installed in the facade frame, the sliding member is hinged to the angle adjustment column, the other end of the angle adjustment column is detachably connected to the base, and the base is hinged to the facade frame;

[0008] The supporting device is movably mounted on the sliding component.

[0009] By adopting the above technical solution,

[0010] Preferably, the angle adjustment column comprises:

[0011] A sliding column, which is detachably connected to the base;

[0012] The connecting column has one end hinged to the sliding column and the other end hinged to the facade frame.

[0013] By adopting the above technical solution, a fastening bolt is arranged between the sliding column and the base. When the bolt is loosened, the two can slide relative to each other. When the bolt is tightened, the sliding column and the base are tightly connected and cannot slide. As the sliding column slides, the lifting height of the facade frame is adjusted through the support column, and the inclination angle of the facade frame is also adjusted accordingly, so as to facilitate testing at different inclination angles.

[0014] Preferably, the sliding member comprises a first crossbar and a second crossbar which are arranged in parallel, the angle adjustment column and the first crossbar are hinged, and both ends of the first crossbar and the second crossbar are slidably connected to the facade frame;

[0015] The supporting device is connected to the first crossbar and the second crossbar at the same time;

[0016] A plurality of first positioning holes are evenly formed on the side of the facade frame, and the first positioning holes are used to fix the first cross bar or the second cross bar to the facade frame.

[0017] By adopting the above technical solution, the distance between the first crossbar and the second crossbar is fixed by the supporting device, and the first crossbar and the second crossbar also play the role of preventing the facade frame from twisting. The first positioning hole is used to fix the facade frame and the corresponding first crossbar or second crossbar by a connecting piece when the end face of the first crossbar or the second crossbar is close to the first positioning hole, so as to facilitate experiments. At the same time, a certain scale can also be set in the first positioning hole so that it can be marked without a ruler.

[0018] Preferably, a limiting cross bar for limiting the downward sliding position of the sliding member is also provided on the inner side of the facade frame.

[0019] By adopting the above technical method, the lower edge of the support device usually exceeds the sliding component during use. If care is not taken during adjustment, the lower edge of the support device may be easily damaged by collision. Therefore, a limiting cross bar is provided to prevent the sliding component from sliding down excessively.

[0020] Preferably, it also includes a storage tank bracket;

[0021] The storage tank support can be detachably mounted on the side edge of the facade frame and / or the sliding member.

[0022] By adopting the above technical solution, the tank bracket is mainly used to place the tank for the electrolyte in the liquid flow battery. In order to adapt to the pump required for the test, the size of the tank cannot be less than a certain specification, otherwise the tank is easily damaged when the flow fluctuates, resulting in test failure. In the process of research and development tests, the electrolyte is almost always manually configured, and the amount configured at a time is usually on the order of one liter, which can only fill the bottom of a conventional tank. There is a certain risk of empty suction. Therefore, a tank bracket is set on the facade frame and the sliding member, so that the tank is leaning against the facade frame or the sliding member to raise the liquid level to avoid the risk of pump empty suction.

[0023] Preferably, the sliding member is also provided with a plurality of connecting rods for the storage tank to abut against, and the connecting rods are located beside the storage tank bracket.

[0024] By adopting the above technical solution, when the storage tank is pumped by the pump, it will often produce a certain vibration as the pump runs. When placed on the storage tank bracket, the storage tank is easily caused to fall due to the vibration. The connecting rod is provided for the storage tank to lean against, and it also plays the role of strengthening the sliding component.

[0025] Preferably, the support device comprises a mounting column, a support column and a stabilizing column;

[0026] The installation columns, support columns and stabilizing columns are connected end to end to form a triangular truss;

[0027] The support column and the sliding component are slidably connected, and the mounting column is provided with a mounting groove for mounting the battery stack and is located in a horizontal direction.

[0028] The beneficial effects of the technical solution provided by this application include:

[0029] The device for testing flow batteries of the present application adjusts the inclination angle of the facade frame by adjusting the angle column, and uses a sliding member to control the relative position of the supporting device and the facade frame, so as to quickly realize the construction of test platforms with various heights and inclination angles.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] Before describing the embodiments of the present application, the technical elements involved in the embodiments of the present application are described. It should be noted that the introduced technical elements are the technical elements selected for the embodiments of the present application, and do not limit the specific implementation methods of the technical elements. Those skilled in the art can select other implementation methods according to the specific content of the technical solution.

[0037] In the provided embodiment, the flow battery used for testing includes a battery stack, a storage tank and a peristaltic pump. The battery stack is a small battery stack formed by pressing three to five single cells together, and the storage tank is a square storage tank with a length, width and height of about 30 cm. There are two storage tanks, one for positive electrode electrolyte and the other for negative electrode electrolyte. The electrolyte is sent to the battery stack through a soft gel pipe and returned to the storage tank after the reaction is completed.

[0038] The present application provides an embodiment of a device for testing a flow battery, comprising a base 1 , a facade frame 2 , an angle adjustment column 3 , a sliding member 4 and a supporting device 5 .

[0039] See also Figure 1 The base 1 is a U-shaped structure surrounded on three sides. The facade frame 2 has one side hinged to it. The facade frame 2 is a rectangular frame with its length pointing to the ground. A sliding member 4 is arranged in the facade frame 2. The two ends of the sliding member 4 are respectively slidably connected to the long side of the facade frame 2. The supporting device 5 is connected to the sliding member 4. When in use, the inclination angle of the facade frame 2 is adjusted by the angle adjustment column 3 to meet the test requirements, and then the battery stack is installed on the top of the supporting device 5. There are many ways to install the battery stack. In this embodiment, the battery stack is fastened to the top of the supporting device 5 by bolts. In some embodiments, a flat plate is placed on the top of the supporting device 5, and then the battery stack is placed on the flat plate.

[0040] During operation, the support device 5 is adjusted to a suitable height from the ground, and then the battery stack is installed, the storage tank is placed on the ground, the battery stack and the storage tank are connected, and a peristaltic pump is installed, and finally the peristaltic pump is started to start the electrolyte circulation.

[0041] See also Figure 2The angle adjustment column 3 includes a sliding column 31 and a connecting column 32, wherein the sliding column 31 is detachably connected to the base 1, so that the sliding column 31 can be removed and installed to other positions of the base 1 when the inclination of the facade frame 2 needs to be adjusted. In some embodiments, in order to facilitate the adjustment of the sliding column 31, a slide rail slider is used to connect the sliding column 31 and the base 1 to limit the direction of the sliding column 31 and facilitate operation. In this embodiment, a weight-reducing groove of a profile is used in combination with a connecting piece such as a bolt to achieve this effect. The connecting column 32 is used to support the facade frame 2, and it is hinged with the angle adjustment column 3 to facilitate rotation.

[0042] See also Figure 1 After adjusting the facade frame 2 to a suitable angle, it is necessary to start adjusting the up and down positions, wherein the sliding member 4 includes a first crossbar 41 and a second crossbar 42. The main purpose of setting the two crossbars is to prevent twisting under the gravity of the support device 5 when there is only one crossbar, and a plurality of first positioning holes are opened on the side of the facade frame 2. The first positioning holes are used to fix the first crossbar 41 or the second crossbar 42 to the facade frame 2 by using a connecting member when the first crossbar 41 or the second crossbar 42 is aligned. Because the first crossbar 41 and the second crossbar 42 form an I-shaped structure with the support device 5, only one crossbar needs to be fixed to fix the entire sliding member 4. At the same time, in some embodiments, the first positioning holes are also set according to the ruler to facilitate direct position reading.

[0043] See also Figure 1 At the bottom of the facade frame 2, a limit cross bar 21 is provided to prevent the sliding member 4 from sliding down excessively. In this embodiment, the limit cross bar 21 is two profiles directly connected to the inner side of the facade frame 2. When the sliding member 4 contacts the profile, according to the different inclination angles of the facade frame 2, the bottom of the support device 5 is still about 1-2 cm away from the ground, which prevents the support device 5 from directly touching the ground during the adjustment process, thereby damaging the support device 5, and also prevents the support device 5 from being held when it is not held. In other embodiments, the position of the limit cross bar 21 can be adjusted according to test needs.

[0044] See also Figure 1, in general, only the battery stack is placed on the support device 5, and the storage tank and pump are placed on the ground to test various performance indicators at different relative heights. However, in the test of screening electrolyte, each test requires the experimenter to configure the electrolyte to test the effect. Considering the cost and the specifications of conventional laboratory equipment, the configuration amount is about 1L at a time. The pump required for the test has certain specification requirements according to the actual situation, and the corresponding storage tank itself has certain requirements to match the pump. A storage tank that is too small is easily damaged by the suction of the pump. Therefore, the electrolyte configured each time can usually only occupy a part of the space of the storage tank, which is easy to cause empty suction during the operation of the pump, that is, the inlet of the liquid extraction pipeline is not completely immersed in the electrolyte, resulting in part of the air being brought in when the electrolyte is sucked, affecting the accuracy of the test results, and also damaging the battery stack and the pump. The usual solution is to let the experimenter configure it several times. In this embodiment, a storage tank bracket 6 is also provided, and the hanging inner bracket is installed on the side of the facade frame 2 or the sliding member 4, and some embodiments are installed in both places. In this embodiment, the tank support 6 is a short profile, which is detachably mounted on the second crossbar 42 of the sliding member 4 and the side of the facade frame 2 through a connector. In this way, the tank itself can be against the two tank supports 6, and the tank can be placed at an angle, which can raise the liquid level, and even the inlet for sucking electrolyte can be set at the bottom of the tank to avoid the occurrence of empty suction.

[0045] See also Figure 1 In this embodiment, a connecting rod 43 is also provided. The connecting rod 43 is mainly located beside the storage tank support 6. In this embodiment, the connecting rod 43 is located between the first crossbar 41 and the second crossbar 42, and is perpendicular to the first crossbar 41 and the second crossbar 42. At the same time, the surface is flush with the first crossbar 41 and the second crossbar 42. The main function of the connecting rod 43 is to support the storage tank against the support, and on the other hand, it can also enhance the strength of the supporting device 5.

[0046] See also Figure 1 and Figure 2 The support device 5 includes a mounting column 52, a support column 51 and a stabilizing column 53. The mounting column 52, the support group and the stabilizing column 53 are connected end to end to form a triangular truss structure, the mounting column 52 is located at the top and is roughly parallel to the ground, and the stabilizing column 53 is located in the vertical direction. When in use, a table or tabletop can be placed on the mounting column 52 to place the battery stack, or the battery stack can be installed on the mounting column 52 through a connector.

[0047] See also Figure 1 A reinforcement member 54 is added between the mounting column 52 and the stabilizing column 53, and between the mounting column 52 and the supporting column 51. The cross-sectional shape of the reinforcement member 54 is similar to an A-shape, and its main function is to strengthen the connection force to prevent the mounting column 52 and the stabilizing column 53, or the mounting column 52 and the supporting column 51 from detaching when bearing load.
