[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following combination Figure 1 The present invention describes a device for measuring sample volume.

[0024] like Figure 1As shown, in an embodiment of the present invention, the sample volume measurement device includes a crane 10, a first housing 20, and a container. The crane 10 is used to lift a sample 100 and place it within the first housing 20. The first housing 20 is provided with multiple first valves 21 along its height. The height of the liquid level within the first housing 20 is equal to the height of any first valve 21. The container is located below the first valve 21 and is used to accommodate the volume of liquid that flows through the first valve 21 and enters the container.

[0025] Specifically, because different samples 100 have different heights, multiple first valves 21 are provided along the height of the first tank 20 to determine which first valve 21 is used to drain the liquid based on the height of the sample 100. In this embodiment, the crane 10 has an adjustable speed, allowing it to quickly lift the object and then slowly place it into the first tank 20 to minimize water surface fluctuations.

[0026] During measurement, select the first valve 21 based on the height of the sample 100 and open it. Liquid is then injected into the first housing 20 until the liquid level reaches the height of the selected first valve 21, and the liquid is then discharged through the first valve 21. The liquid is allowed to stand until the liquid level calms down and no more liquid is discharged from the first valve 21, and then the first valve 21 is closed.

[0027] The crane 10 slowly places the sample 100 in the first box 20 until the sample 100 is completely submerged in the liquid. The sample is allowed to stand until the liquid surface is calm, and the first valve 21 is opened to allow the liquid to flow into the container until the liquid stops flowing into the container. The volume of the liquid in the container is the volume of the sample 100. In an embodiment of the present invention, the container may be a measuring cylinder 30, and the volume of the liquid in the measuring cylinder 30 is recorded, which is the volume of the sample 100. If there is no measuring cylinder 30, the container may be weighed before the test, and after the liquid is drained into the container, the container and liquid are weighed together. The difference between the two is the weight of the liquid. The volume of the sample 100 can also be calculated by dividing the weight by the density of the liquid.

[0028] Furthermore, in Figure 1 In the embodiment shown, there are two first valves 21. When the height of the sample 100 is relatively low, the first valve 21 with the lower height can be selected; and when the height of the sample 100 is greater than the height of the first valve 21 with the lower height, the first valve 21 with the higher height can be selected for testing.

[0029] Optionally, in an embodiment of the present invention, the liquid may be water or other non-volatile liquids.

[0030] In this embodiment, the sample 100 is a vehicle battery pack.

[0031] The sample volume measuring device provided by the embodiment of the present invention, by arranging a crane, a first box body and a container, can put the sample into the first box body when the liquid in the first box body is consistent in height with the first valve. The sample occupies the space in the first box body, and the excess liquid is discharged into the container. The volume of the liquid in the container is the volume of the sample, and the volume of the sample can be quickly obtained; the first box body is provided with a plurality of first valves, and different first valves can be opened according to the height of the sample, so that the volume of samples at different heights can be measured, thereby improving the application range of the measuring device; at the same time, by arranging the first valve, the liquid flow rate can be adjusted. At the beginning of the measurement, a large flow rate is used, and a small flow rate is used near the end. This can keep the liquid level calm when the liquid level drops, thereby preventing errors caused by liquid level fluctuations.

[0032] In an embodiment of the present invention, the sample volume measuring device further comprises a plurality of strips. The inner wall of the first box body 20 is provided with a plurality of strips at the height where the first valve 21 is located, and each strip is provided with a plurality of protrusions on the surface facing away from the first box body 20 .

[0033] Specifically, the inner wall of the first box body 20 is provided with a plurality of strips at the height of each first valve 21, and the surface of each strip is provided with a plurality of protrusions to reduce the water surface fluctuations and water wave reflections generated when the sample 100 is placed, so as to calm the water surface as soon as possible.

[0034] In an embodiment of the present invention, the sample volume measuring device further includes a bracket, the crane 10 is disposed on the bracket, and the first box 20 is located below the crane 10 .

[0035] Furthermore, the crane 10 can slide along the bracket to lift the sample 100 and then lift the sample 100 above the first box 20 .

[0036] like Figure 1 As shown, in an embodiment of the present invention, the bracket includes: a column 60, a rotating shaft 61 and a crossbeam 62, the column 60 is used to be set on the ground, the rotating shaft 61 is rotatably connected to the column 60, the crossbeam 62 is connected to the rotating shaft 61, and the crane 10 is slidably connected to the crossbeam 62.

[0037] Specifically, the rotating shaft 61 is connected to the crossbeam 62. The rotating shaft 61 can rotate around the column 60, thereby driving the crossbeam 62 to rotate, so that the crane 10 can be moved to another position. The crossbeam 62 is provided with a slideway, and the crane 10 can slide along the slideway to adjust the position of the crane 10. The crane 10 is moved to the sample 100, and the sample 100 is lifted. The crane 10 is then rotated and slid along the crossbeam 62 to adjust the position of the crane 10 so that the sample 100 is located above the first box 20.

[0038] The sample volume measuring device provided in the embodiment of the present invention can change the position of the crane to lift samples placed at different positions by setting up columns, rotating shafts, and beams, and setting slide grooves on the beams, thereby improving the convenience of using the measuring device.

[0039] like Figure 1 As shown, in an embodiment of the present invention, the sample volume measuring device further includes a plurality of support plates 63, which are respectively provided at the connection between the upright column 60 and the ground, and at the connection between the rotating shaft 61 and the crossbeam 62. The support plates 63 act as reinforcing ribs to ensure a firm connection at the connection.

[0040] like Figure 1 As shown, in an embodiment of the present invention, the sample volume measuring device further includes a second valve 22 . The second valve 22 is disposed in the first box 20 , and the height of the second valve 22 is smaller than that of the first valve 21 .

[0041] Specifically, the second valve 22 is used to drain the liquid in the first box 20 after the measurement is completed, so the second valve 22 is disposed at a position close to the bottom surface of the first box 20.

[0042] like Figure 1 As shown, in the embodiment of the present invention, the bottom surface of the first box body 20 is further provided with a roller 23, so that the first box body 20 can be pushed to the water source to receive water and then locked to prevent the first box body 20 from moving.

[0043] like Figure 1 As shown, in the embodiment of the present invention, when the container is a measuring cylinder 30 , there may be multiple measuring cylinders 30 , and the volumes of the multiple measuring cylinders 30 are different.

[0044] Specifically, when the cross-sectional dimensions of the sample 100 are the same but the heights are different, the volume of the sample 100 will also vary, and the volume of the liquid discharged into the container will also vary. For example, when the sample 100 is tall and the first valve 21 near the top surface of the first housing 20 needs to be opened, a taller graduated cylinder 30 can be configured so that the top surface of the graduated cylinder 30 is closer to the first valve 21, preventing the discharged liquid from splashing out of the graduated cylinder 30. Furthermore, the taller graduated cylinder 30 also has a larger volume and can accommodate more liquid.

[0045] like Figure 1 As shown, in an embodiment of the present invention, the sample volume measuring device further includes a second box body 50, and the second box body 50 is used to recycle the used liquid to achieve liquid reuse.

[0046] Furthermore, in an embodiment of the present invention, the sample volume measuring device also includes a water bucket 70. When the volume of the measuring cylinder 30 is small and cannot hold all the liquid at one time, the volume of the liquid held each time can be recorded and poured into the water bucket 70. The volumes recorded multiple times are superimposed to obtain the volume of the sample 100.

[0047] The sample volume measuring device provided by the embodiment of the utility model has the following characteristics: the water surface is at the same height before and after the sample is immersed, thereby reducing the influence of the cross-sectional error of the first box body; the use of a customized calibrated large-volume graduated cylinder improves the measurement accuracy; when there is no graduated cylinder, valve control is adopted, and a small graduated cylinder or a small bucket can be used to measure separately, and finally add and summarize the results, which provides a flexible measurement method.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
