[0002] In recent years, with the continuous advancement of science and technology, colloidal battery technology has also been continuously improved and perfected. The development of nanoscale sols and the electrochemical application of surfactants have made the performance of colloidal batteries even superior. In lead-acid batteries, silica is primarily used in the colloidal electrolyte as a gelling agent. The purity, particle size, gel stability, and gel strength of silica have a significant impact on battery performance. Gel strength is mainly tested by visual code inspection and the falling ball method. The falling ball method is simple, quick, and can achieve rapid detection, making it widely used.

[0003] The falling ball method is an experimental method used to measure gel strength, particularly in the battery field, to assess the strength of gels. This method involves dropping a small ball of specified dimensions vertically from a predetermined height. The ball is then sunk to a predetermined depth within the gel being tested, and the depth of penetration is used to measure the gel's strength. However, existing techniques using the falling ball method can only test one sample at a time, resulting in low test efficiency or requiring manual insertion of the ball into the gel, resulting in poor accuracy.

[0031] Please refer to Figure 1 , an embodiment of the present application provides a gel detection device 100. The gel detection device 100 provided in the embodiment of the present application can be used to perform strength detection on silica gel. The gel detection device 100 includes: a base 110, a main shaft 120, a limit assembly 130 and a sample conversion assembly 140. Among them, the main shaft 120 is vertically arranged on the base 110 in the vertical direction. The limit assembly 130 is arranged on the main shaft 120, and is used to automatically fix and release the detection steel ball. The sample conversion assembly 140 is movably connected to the base 110. The sample conversion assembly 140 includes at least two sample accommodating units. Each of the sample accommodating units is used to accommodate a gel sample to be detected. Each of the sample accommodating units is movably arranged below the limit assembly 130.

[0032] The gel testing device 100 provided in the embodiment of the present application is used to test gel strength using the drop ball method. The limit assembly 130 automatically secures and releases the test steel ball, reducing test errors and achieving high test accuracy and uniformity. Simultaneously, the sample transfer assembly 140 moves multiple sample accommodating units to the limit assembly 130 for testing, resulting in high test efficiency. Furthermore, the limit assembly 130 automatically releases the test steel ball, fixing the position where the test steel ball is released, ensuring that the steel ball on the limit assembly 130 falls to the center of the corresponding test tube 150, preventing it from rubbing against the tube wall and affecting the test results, further improving test accuracy.

[0033] In a feasible embodiment, the sample conversion assembly 140 includes a rotating member 141. The sample accommodating unit is arranged on the rotating member 141. Each of the sample accommodating units accommodates a detection test tube 150. The rotating member 141 can rotate around a central axis so that the target detection test tube 150 is located below the limiting assembly 130. By loading or feeding the limiting assembly 130 through the rotating member 141, space can be saved. Furthermore, rotary loading helps to ensure the uniform distribution of samples in the target area. Rotary loading can speed up sample processing, especially when processing a large number of samples, it can significantly improve work efficiency. Loading by rotation can reduce contact between samples, thereby reducing the risk of cross contamination.

[0034] In a feasible embodiment, the sample holding unit is a holding space provided in the vertical direction on the rotating member 141. The vertical upward holding space mentioned here can be a hole opened on the rotating member 141, and the detection test tube 150 is inserted into the hole. In this way, the rotating member 141 can itself have a certain thickness, the hole does not pass through the rotating member 141 itself, and the bottom of the detection test tube 150 is against the inner wall of the bottom of the hole of the rotating member 141. There can also be a slot on the rotating member 141 to clamp the detection test tube 150. The rotating member 141 can also be a tubular hollow holding space extending upward from the plane where the upper surface of the rotating member 141 is located, and the detection test tube 150 is inserted into the tube. In this way, the detection test tube 150 can also be fixed to improve the accuracy of the detection.

[0035] In a feasible embodiment, the sample accommodating unit may also be a holding space provided by a clamping component such as a clamping claw, which can be used to keep the test tube 150 in a vertical state and to position the test tube 150.

[0036] In one feasible embodiment, six sample accommodating units are provided on the rotating member 141. The six sample accommodating units can accommodate six test tubes 150, corresponding to three time periods of gel samples to be tested. With two samples per sample, a total of six test tubes can be used to fully test a gel in one group, with unified records and good uniformity, thereby improving detection efficiency and accuracy.

[0037] In a feasible implementation manner, the rotating member 141 may also be provided with a number of sample accommodating units other than six, which is set according to different detection requirements and will not be described in detail here.

[0038] In one possible embodiment, the six sample-holding units are evenly distributed around the central axis. When the six sample-holding units are evenly distributed, the entire device is balanced during rotation, reducing vibration and noise, and improving the stability and lifespan of the device. This layout promotes uniformity during sample testing or processing, ensuring that each sample is tested under the same conditions, reducing errors. Evenly distributing samples effectively utilizes space, making sample loading, testing, and unloading more efficient and shortening overall processing time. The six evenly distributed sample-holding units simplify the mechanical design, making the rotation device easier to implement and reducing manufacturing complexity. A well-designed rotation path reduces physical contact between samples, thereby reducing the risk of cross-contamination. This layout helps optimize resource allocation. For example, during testing, it ensures that each sample receives adequate illumination or contact, improving test quality. The evenly distributed design simplifies maintenance and cleaning because all components are symmetrically distributed. This layout provides greater flexibility when adding or removing samples, allowing the number and position of samples to be easily adjusted as needed. Since each sample-holding unit is in a similar position and under similar conditions, this helps improve the reliability and consistency of the entire system. If the number of samples needs to be increased or decreased, this layout can be easily achieved by adding or reducing sample holding units.

[0039] In a feasible embodiment, the six sample receiving units can also be grouped in two groups, divided into three groups in total, and the three groups are evenly distributed around the central axis. This can also ensure a certain uniformity and stability, facilitating the reading and analysis of experimental results.

[0040] In a feasible embodiment, the sample conversion assembly 140 further includes a rotating shaft 142, a bearing and a limiting structure. The rotating shaft 142 is fixedly connected to the base 110. The rotating member 141 is fixedly connected to the rotating shaft 142 so that the rotating member 141 rotates around the rotating shaft 142. The limiting structure is used to control the rotating member 141 to rotate at an angle of 60° each time. Such a sample conversion assembly 140 has good stability. The limiting structure can also ensure uniformity during each rotation, ensuring that the steel ball on the limiting assembly 130 can fall to the center position of the corresponding test tube 150 to avoid rubbing against the test tube wall and affecting the test results.

[0041] In one feasible embodiment, the sample transfer assembly 140 can also utilize a sliding assembly for linear sample loading. For example, sample loading can be performed via a linear module perpendicular to the main shaft 120 and perpendicular to the length of the position-limiting assembly 130. The linear module is provided with multiple holes for accommodating test tubes 150. By horizontally moving the position of the linear module's moving block, the test tubes 150 in different holes are moved to below the detection steel balls of the position-limiting assembly 130. This allows for simultaneous sample loading and testing of multiple samples or specimens, improving detection efficiency.

[0042] In one possible embodiment, the rotating member 141 is made of ABS (acrylonitrile butadiene styrene), a common engineering plastic. Using ABS to manufacture the rotating member 141 has the following advantages: ABS has high impact strength and rigidity, allowing it to withstand significant external forces without breaking. It also has good wear and fatigue resistance, making it suitable for parts requiring long-term use. ABS is easy to process and mold, suitable for various molding processes such as injection molding, extrusion, and blow molding. Its good fluidity allows for the production of parts with complex shapes. ABS exhibits excellent corrosion resistance to most acids, bases, and salt solutions. Therefore, even a spill of a gel, such as silica gel, will not cause significant damage. ABS maintains its properties over a wide temperature range, exhibiting excellent low-temperature toughness and a high heat deflection temperature. Its operating temperature range is approximately -20°C to +80°C, with some specialized grades capable of withstanding even higher temperatures. ABS is recyclable, helping to reduce environmental pollution. After molding, ABS is dimensionally stable and less susceptible to warping and deformation. ABS also exhibits a certain degree of UV resistance, making it suitable for outdoor applications. Compared to other high-performance engineering plastics, ABS is relatively low-cost and offers a high cost-effectiveness.

[0043] In one feasible embodiment, a first scale is provided on the sidewall of each test tube 150. By providing the first scale, the height at which the test ball falls can be recorded and the height at which the test ball falls can be adjusted according to the first scale, thereby expanding the application scenarios of the device and facilitating widespread application.

[0044] In one feasible embodiment, the sidewall of the main shaft 120 is provided with a second scale 121. The second scale 121 can record the depth of the test ball sinking into the gel, as well as the initial liquid level of the gel, to facilitate recording of experimental results.

[0045] In a feasible embodiment, the rotating member 141 may be made of a transparent material, and the outer wall of the sample containing unit may also be provided with a third scale to further record the gel height of the test tube 150 .

[0046] In one possible embodiment, the limiting assembly 130 includes a connector 131 and an electromagnetic element 132. The connector 131 is connected to the main shaft 120. The electromagnetic element 132 is fixedly connected to the connector 131. The electromagnetic element 132 electromagnetically attracts the detection steel ball. The electromagnetic element 132, the detection steel ball, and the vertical centerline of the target detection test tube 150 are aligned vertically. The detection steel ball is made of steel. The magnetic strength of the electromagnet can be adjusted by the current passing through the coil, meaning its magnetic strength can be easily adjusted as needed. The electromagnet can be turned on and off by switching the current, allowing the presence of magnetism to be controlled at any time. This allows for automatic attraction and release of the detection steel ball, improving detection uniformity and accuracy. The electromagnet can be turned off when not in use, which helps save energy. The shape and size of the electromagnet can be customized to meet specific application requirements. For example, a groove can be customized to limit the detection steel ball, further securing its position and preventing it from contacting the walls of the detection test tube 150. The electromagnet can improve the automation and mechanization of the equipment, increase detection efficiency, and reduce labor costs. At the same time, it can ensure that the steel ball on the limit assembly 130 can fall to the center of the corresponding test tube 150, avoiding rubbing against the test tube wall and affecting the detection results.

[0047] In one feasible embodiment, the position limiting assembly 130 further includes a power supply for an automatic ball drop device. The electromagnetic component 132 is connected to the power supply for the automatic ball drop device. The power supply for the automatic ball drop device is provided with a control switch, and the electromagnetic component 132 is controlled to attract or release the detection steel ball by turning the power supply on and off.

[0048] In one feasible embodiment, the limiting assembly 130 further includes an adjusting member 133. The connecting member 131 has a through hole, and the adjusting member passes through the through hole and abuts the main shaft 120. By loosening the adjusting member 133, the position of the connecting member 131 on the main shaft 120 can be adjusted to adjust the initial height of the detection steel ball.

[0049] In a feasible embodiment, the gel detection device 100 provided in the embodiment of the present application is specifically implemented as follows: 8g of gel sample is weighed and placed in a 250ml tall beaker, 72ml of pure water is added to prepare a 10% silica masterbatch solution, and then 80ml of 1.28g / cm 3The sulfuric acid solution was sheared for 5 minutes on a shearing machine with a speed of 10,000 r / min, and then the evenly dispersed silica solution was transferred to 6 test tubes 150, with the liquid level of each test tube 150 being 12 cm. The 6 test tubes 150 were placed in a constant temperature water bath at 45°C for testing. Two test tubes were taken out after 24 hours, 48 ​​hours, and 72 hours respectively, and placed in the sample holding unit of the rotating part 141 of the rotating sample conversion component 140 of the gel detection device 100. The power switch of the automatic ball falling device connected to the electromagnetic part 132 in the limit component 130 was turned on, a 0.35g steel ball was selected and adsorbed on the electromagnetic part 132, and the height of the connecting part 131 on the first scale of the main shaft 120 was adjusted. When the height of the ball was 50 cm, the power was cut off to allow the ball to fall freely. After the ball fell into the test tube, the data was recorded through the second scale 121 on the wall of the test tube 150. At the same time, the rotating member 141 of the sample conversion assembly 140 is rotated to test the sample in another test tube 150 and record the data.

[0050] The gel detection device provided in the embodiments of the present application enables more accurate detection of the falling height and position of the steel ball. Furthermore, the absence of other tube walls affecting the ball's velocity during the falling process ensures the ball's free fall, eliminating human error and resulting in more accurate experimental results. Furthermore, multiple sample holding units can test gel samples at multiple time intervals and retain the samples, improving detection efficiency and avoiding errors such as incorrect sample sequencing and recording errors.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
