Description

Technical Field

[0001] The present application relates to the technical field of automatic watering, and in particular to an automatic watering device for detecting vertical expansion rate. Background Art

[0002] Grouting materials, as a widely used foundation material, undergo multiple tests and performance tests before being put into use. The vertical expansion rate of the grouting material is a key performance test indicator. However, according to Appendix C, Determination of Vertical Expansion Rate, of GB / T 50119, "Technical Specifications for the Application of Concrete Admixtures," watering is required every two hours for four consecutive times, starting from the initial reading. Thereafter, watering is required every four hours until the required age. Furthermore, vertical expansion rate testing involves a 24-hour expansion rate test, making it difficult to meet the required moisture retention requirements at night. To ensure data accuracy, experimenters need to spray water on the grouting material under test on a regular basis to maintain the humidity within the test's required range. This lengthy test period requires dedicated personnel to monitor the operation, increasing the workload and fatigue of the experimenters.

[0003] Regarding the above-mentioned related technologies, the grouting materials undergoing vertical expansion rate testing are manually sprayed with water at regular intervals for moisturizing according to the testing requirements, which greatly consumes labor costs and has poor stability, resulting in errors in the experimental data.

[0055] The following is combined with Figure 1-3 This application is described in further detail.

[0056] An embodiment of the present application discloses an automatic water adding device for detecting the vertical expansion rate.

[0057] Reference Figure 1 The automatic water-adding device for detecting the vertical expansion rate includes a base 1, a mold 2, a screw 3, a fixed frame 4, a water spray assembly 5, two sets of mobile assemblies 6, a control unit 7, and an expansion rate detection assembly 8. The mold 2 is detachably mounted on the base 1, the screw 3 is threadedly connected to the base 1, the fixed frame 4 is fixedly mounted on the screw 3, the water spray assembly 5 is mounted on the fixed frame 4, the water spray assembly 5 is mounted on the two sets of mobile assemblies 6 for controlling the movement of the water spray assembly 5, the water spray assembly 5 is connected to the control unit 7 for controlling the timing of water spraying by the water spray assembly 5, and the expansion rate detection assembly 8 is mounted on the fixed frame 4 for measuring the vertical expansion rate of the grouting material.

[0058] When the automatic water-adding device for detecting the vertical expansion rate is in use, the base 1 is placed on the operating table, the mold 2 is placed on the base 1, the mold 2 is filled with the grouting material whose expansion rate needs to be detected, and the expansion rate detection component 8 performs vertical expansion rate detection on the grouting material. The screw 3 installs the fixed frame 4 above the mold 2, and the fixed frame 4 is used to fix the water spraying component 5. The water spraying component 5 sprays water on the grouting material to be detected in the mold 2. The moving component 6 moves the water spraying component 5 to achieve uniform spraying of the grouting material. The control unit 7 controls the water spraying component 5 to spray water at a fixed time, thereby realizing automatic watering at a fixed time when the vertical expansion rate of the grouting material is detected, thereby meeting the moisturizing requirements during the detection process.

[0059] Reference Figure 2 and Figure 3 The water spray assembly 5 includes a water tank 51 fixedly mounted on the fixed frame 4, a water pump 52 fixedly mounted in the water tank 51, and two water pipes 53 connected to the water outlet of the water pump 52. The end of the water pipe 53 close to the nozzle 54 is a bellows, so that the length of the water pipe 53 can change in the axial direction. The water pipe 53 is passed through and fixed on the water tank 51. A sealing plug 9 is fixedly mounted at the connection between the water pipe 53 and the water tank 51, and a filter 55 is fixedly mounted at the connection between the water pipe 53 and the water tank 51. The end of the water pipe 53 away from the water pump 52 is connected to the nozzle 54, and the nozzle 54 is connected to the movable assembly 6. At the same time, the control unit 7 is connected to the water spray assembly 5. The control unit 7 includes a time relay 71 fixedly mounted on the fixed frame 4 and an electromagnetic valve 72 connected to the water pipe 53. The electromagnetic valve 72 and the water pump 52 are both electrically connected to the time relay 71.

[0060] When the automatic water-adding device for detecting the vertical expansion rate is in use, sufficient water is added to the water tank 51, and the watering time is set for the time relay 71. When the watering time comes, the time relay 71 controls the water pump 52 to start running, and the water in the water tank 51 is pumped into the water pipe 53 through the water pump 52. The sealing plug 9 prevents water leakage at the connection between the water tank 51 and the water pipe 53, and the filter 55 prevents impurities in the water from being sprayed into the grouting material to be tested. The time relay 71 simultaneously controls the electromagnetic valve 72 to energize, and the valve is opened. The water in the water pipe 53 is sprayed from the nozzle 54 through the electromagnetic valve 72 to the grouting material placed in the mold 2, realizing timed water spraying, making the experiment more standardized.

[0061] Reference Figure 2 and Figure 3 The expansion rate detection assembly 8 includes a glass plate 81 covered on the mold 2 and a micrometer 82 fixedly mounted on the fixed frame 4. The detection end of the micrometer 82 is in contact with the glass plate 81. During detection, the axis of the micrometer 82 is ensured to be perpendicular to the glass plate 81.

[0062] When the automatic water adding device for detecting the vertical expansion rate is in use, the grinding mold 2 is filled with the grouting material whose vertical expansion rate needs to be tested, the glass plate 81 is covered on the grouting material in the mold 2, and the detection end of the micrometer 82 is in contact with the glass plate 81. The vertical expansion rate of the grouting material is detected by the ups and downs of the glass plate 81. If the surface of the grouting material is tested directly, there will be a large measurement error due to the insufficient flatness of the surface of the grouting material. Therefore, the ups and downs height of the glass plate 81 is measured to improve the accuracy of the experimental data.

[0063] Reference Figure 2 and Figure 3 The two sets of moving assemblies 6 each include two fixed blocks 61, a cylindrical cam 62, a motor 63, a slide rod 64, and a slider 65. The two sets of moving assemblies 6 are mounted on either side of the glass plate 81. The two fixed blocks 61 are symmetrically and fixedly mounted on the outer wall of the mold 2. The cylindrical cam 62 is rotatably mounted on the fixed blocks 61. The output end of the motor 63 is coaxially and fixedly connected to the cylindrical cam 62. The motor 63 is electrically connected to the time relay 71. The slide rod 64 is fixedly mounted on the fixed blocks 61. The slider 65 is slidably mounted on the cylindrical cam 62. The nozzle 54 is fixedly connected to the slider 65.

[0064] When the automatic water-adding device for detecting the vertical expansion rate is in use, the time relay 71 controls the motor 63 to be powered on and started, the motor 63 drives the cylindrical cam 62 to rotate, and the cylindrical cam 62 drives the slider 65 to slide in the groove of the cylindrical cam 62, and at the same time drives the slider 65 to move on the slide rod 64, so that the nozzle 54 is moved, so that the grouting material is evenly watered during the detection process to meet the detection moisture requirements.

[0065] The implementation principle of an automatic water-adding device for detecting vertical expansion rate in an embodiment of the present application is as follows: when the automatic water-adding device for detecting vertical expansion rate is used, the base 1 is placed on the operating table, the mold 2 is placed on the base 1, the grouting material whose vertical expansion rate is to be detected is filled in the mold 2, the glass plate 81 is covered on the grouting material, and the grouting material is tested by the micrometer 82. During the test, sufficient water is added to the water tank 51, and the water pump 52 and the electromagnetic valve 72 are controlled by the time relay 71 so that the water in the water tank 51 is sprayed into the grouting material from the nozzle 54 at a fixed time, thereby achieving timed watering of the grouting material and meeting the experimental moisturizing requirements. The time relay 71 simultaneously controls the motor 63 to be energized, and the motor 63 drives the cylindrical cam 62 to rotate, thereby driving the nozzle 54 to move, and spraying water evenly on the grouting material to ensure the accuracy of the test data.

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
