Description

Technical Field

[0001] The utility model relates to the technical field of mortar detection, and more specifically to a mortar underwater anti-dispersion test device. Background Art

[0002] Since its discovery, Portland cement has rapidly become the most commonly used material in engineering construction due to its numerous advantages, including high strength, durability, plasticity, widespread availability, and low cost. Therefore, it is indispensable in the construction of underwater structures and facilities. Although cement, as a hydraulic material, can set and harden in water, when it is prepared into mortar and applied directly underwater, the water scouring as the mortar falls not only causes the cement paste to disperse, but also invades the cement paste, increasing the water-cement ratio. This results in low strength and poor internal uniformity in the hardened mortar, making it unable to meet construction requirements. Therefore, underwater anti-dispersion testing is extremely important for evaluating the underwater anti-dispersion performance of mortars.

[0003] At present, the commonly used method for underwater anti-dispersion test of cement mortar is to manually extract the solution, measure the pH value, turbidity and other indicators at various positions in the solution, and then take the average value. This method is greatly affected by human factors and cannot guarantee that the liquid at various positions is extracted at the same time. There are certain errors, making it difficult to ensure the accuracy and uniformity of the experimental results. Utility Model Content

[0004] In order to overcome the defects of the existing technology, the utility model proposes a mortar underwater anti-dispersion test device. By controlling several electric pipettes to synchronously take samples and detect, it can significantly reduce test errors and avoid the influence of human operation factors, thereby improving test efficiency and the accuracy of test results.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides a mortar underwater anti-dispersion test device, including a slurry placement tube, a lifting module, an electric pipette, a test module and a control panel, wherein more than two electric pipettes are evenly arranged along the circumference on the inner side of the slurry placement tube, the lifting module is fixed on the inner side wall of the slurry placement tube, and the lifting module is connected to the electric pipette, a test module is arranged on the inner side of the electric pipette, and a control panel is also arranged on one side of the slurry placement tube, and the lifting module, the electric pipette and the test module are all electrically connected to the control panel.

[0007] In a better technical solution of the present invention, the lifting module consists of a driver, a movable plate and a clamp. The driver is fixed on the inner wall of the slurry placement cylinder, the output end of the driver is connected to the movable plate, and the movable plate is provided with a clamp for fixing the electric pipette.

[0008] In a preferred technical solution of the present utility model, a total of 8 electric pipettes are provided.

[0009] In a preferred technical solution of the present invention, the test module is a pH meter or a turbidity meter.

[0010] In a preferred technical solution of the present invention, a start button and a stop button are further provided on one side of the slurry placement barrel, and the start button and the stop button are both electrically connected to the control panel.

[0011] In a preferred technical solution of the present invention, the control panel includes a pH meter control panel and a turbidity meter control panel.

[0012] The beneficial effects of the utility model are:

[0013] The utility model proposes a mortar underwater anti-dispersion test device, which uses a control panel to synchronously control several electric pipettes to synchronously descend and absorb slurry. Compared with traditional manual operation, it has the advantage of unified operation, and the electric pipette can be accurately moved to the required sampling position by moving the button up and down. The pH meter and turbidity meter are capable of measuring the pH value and turbidity of the extracted slurry, and summarizing and averaging them on the control panel. In addition, the device can calculate the pH value and the average turbidity of the solution based on the pH value and turbidity of the solution taken at each position, thereby evaluating the underwater anti-dispersion of the mortar. At the same time, by precisely controlling the electric pipette to synchronously extract the slurry at each position, it can significantly reduce the test error, avoid the influence of human operation factors, and improve the test efficiency and the accuracy of the test results.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0022] like Figure 1-5 As shown, an embodiment provides a mortar underwater anti-dispersion test device, including a slurry placement tube 1, a lifting module 2, an electric pipette 3, a test module 4 and a control panel 5. Two or more electric pipettes 3 are evenly arranged along the circumference of the inner side of the slurry placement tube 1. The lifting module 2 is fixed on the inner side wall of the slurry placement tube 1, and the lifting module 2 is connected to the electric pipette 3. A test module 4 is arranged inside the electric pipette 3. A control panel 5 is also provided on one side of the slurry placement tube 1. The lifting module 2, the electric pipette 3 and the test module 4 are all electrically connected to the control panel 5. In this embodiment, the slurry placement tube 1 is a cylindrical cylinder for holding mortar. The electric pipette 3 is arranged vertically, and the number of lifting modules 2 corresponds to the number of electric pipettes 3. Each lifting module 2 is connected to one of the electric pipettes 3. The lifting module 2 can control the synchronous lifting and lowering of several electric pipettes 3, so that the bottom ends of the electric pipettes 3 are simultaneously inserted into the mortar slurry, thereby performing synchronous sampling and testing on multiple positions at one time, which helps to improve the detection accuracy. The electric pipette 3 automatically draws mortar slurry, which is then tested by the testing module 4 to determine the mortar's underwater anti-dispersion properties. A control panel 5 controls the coordinated operation of the lifting module 2, the electric pipette 3, and the testing module 4 to achieve automated testing, eliminating the influence of manual operation and improving test efficiency and the accuracy of test results.

[0023] Specifically, the lifting module 2 is composed of a driver 21, a movable plate 22 and a clamp 23. The driver 21 is fixed on the inner wall of the slurry placement tube 1. The output end of the driver 21 is connected to the movable plate 22. The movable plate 22 is provided with a clamp 23 for fixing the electric pipette 3. In this embodiment, the driver 21 can drive the movable plate 22 to move up and down, and the movable plates 22 arranged at intervals are connected as a whole through a transmission member, so that several movable plates 22 can be lifted and lowered synchronously, thereby accurately moving the electric pipette 3 to the required measurement position at the same time, greatly reducing the error caused by human operation. The transmission member is preferably an arc rod. Two clamps 23 are provided on each movable plate 22, and the clamps 23 are used to clamp and fix the upper and lower ends of the electric pipette 3, and make the heights of several electric pipettes 3 consistent.

[0024] Specifically, a total of 8 electric pipettes 3 are provided.

[0025] Specifically, the test module 4 is a pH meter 41 or a turbidity meter 42. In this embodiment, the pH meter 41 is used to detect the pH value of the slurry, and the turbidity meter 42 is used to detect the turbidity of the slurry. The pH meter 41 and the turbidity meter 42 are arranged in the middle of the electric pipette 3 to reduce the errors in the pH value and turbidity values ​​and ensure that the amplitude of the values ​​does not change too much. The control panel 5 can evaluate the underwater anti-dispersion property of the mortar based on the average values ​​of the pH value and turbidity of the slurry. In addition, the pH meter 41 and the turbidity meter 42 are both commercially available parts. Four pH meters 41 and four turbidity meters 42 are provided, and the pH meters 41 and the turbidity meters 42 are arranged at intervals.

[0026] Specifically, a start button 6 and a stop button 7 are provided on one side of the slurry placement tube 1, and both are electrically connected to the control panel 5. In this embodiment, the provision of the start button 6 and the stop button 7 provides integrated control of the entire device. Furthermore, the start button 6 and the stop button 7 are housed in rust-proof and shock-proof metal casings, preventing electric shock injuries during the test.

[0027] Specifically, the control panel 5 includes a pH meter control panel 51 and a turbidity meter control panel 52. In this embodiment, the pH meter control panel 51 is provided with four buttons: "Move Up," "Move Down," "Absorb Solution," and "Measure Solution pH." The pH meter control panel 51 can control the four electric pipettes 3 equipped with the pH meter 41 to simultaneously move downward and absorb the slurry, and then the pH meter 41 measures the slurry pH value, and then the four values ​​are averaged. The turbidity meter control panel 52 is provided with four buttons: "Move Up," "Move Down," "Absorb Solution," and "Measure Solution Turbidity." The turbidity meter control panel 52 can control the four electric pipettes 3 equipped with the turbidity meter 42 to simultaneously move downward and absorb the slurry, and then the turbidity of the slurry is measured by the turbidity meter 42, and then the four values ​​are averaged.

[0028] Working Principle: To use, first fill the slurry container 1 halfway with water. Add approximately 1 kg of mortar to the water at a distance of 1 to 2 cm from the water surface and let it sit for 30 seconds. Then, power on the mortar underwater anti-dispersion tester and press the start button 6. Then, press the down button on both the pH meter control panel 51 and the turbidity meter control panel 52. This causes the lifting module 2 to move the electric pipette 3 to a distance of approximately 1 to 2 cm from the bottom of the slurry container 1. Then, press the aspiration buttons on both the pH meter control panel 51 and the turbidity meter control panel 52, causing the electric pipette 3 to automatically aspirate the slurry. After aspiration is complete, press the measurement buttons on both the pH meter control panel 51 and the turbidity meter control panel 52 to measure the pH and turbidity of the solution. Four pH and turbidity measurement results are displayed on the respective control panel displays, and the four results are averaged. The average pH and turbidity values ​​of the solution can be used to assess the underwater anti-dispersion properties of the mortar.
