Description

Technical Field

[0001] The utility model belongs to the technical field of wet-dry cycle experimental equipment, and more specifically, it particularly relates to a water replenishing device for large-size soil column wet-dry cycle experiments. Background Technique

[0002] During the wet-dry cycle experiment, a conventional ring cutter is often used. However, in terms of experimental accuracy, the larger the size, the smaller the error. Therefore, in order to better simulate the working conditions, large-size soil column wet-dry cycle experiments are required to simulate the influence of groundwater seepage on soil. However, when conducting large-size soil column wet-dry cycle experiments, a special water replenishing device is generally needed to replenish water to the large-size soil column. The existing water replenishing device generally consists of a glass tube, a bracket, an electronic scale, and a connecting tube. Water is added to the inside of the glass tube at the same time, and the water inside the glass tube replenishes water to the large-size soil column through the connecting tube.

[0003] The existing application number is: CN201920258443.9. The utility model discloses a natural drying wet-dry cycle test box, which includes a box body. A bracket is detachably arranged outside the box body, a control room is arranged on the bracket, a hoist is arranged at the top of the bracket, and the hoist is electrically connected to the control room. A sample chamber is detachably arranged inside the box body, a sample rack is hung in the sample chamber, and a blower is detachably arranged inside the box body. The utility model uses the means of natural air drying and drying with a normal temperature blower to simulate the drying state. The ion concentration and water temperature can be monitored in real time and compensated according to needs, fully restoring the actual working state of the material, avoiding experimental result errors caused by temperature and humidity differences brought by oven baking, and also avoiding experimental result errors caused by the decrease in solution concentration due to the reaction between the material and the immersion solution, improving the reliability and rigor of the test results, and using a multi-layer sample rack, multiple groups of tests can be carried out simultaneously.

[0004] Based on the above, the glass tube of the existing water replenishing device is generally arranged inside the bracket. Since the glass tube has been in a fixed position of the bracket, when replenishing water to the large-size soil column, the water pressure inside the glass tube has always been in a constant state. Since the forming materials of many large-size soil columns are different, the required water pressure is also different. When changing the water pressure, the existing water replenishing device needs to replace the glass tube, resulting in a small application range of the existing water replenishing device. Content of the Utility Model

[0005] To solve the above technical problems, the present utility model provides a water replenishing device for large-sized soil column wet-dry cycle experiments, so as to solve the problem that the glass tubes of existing water replenishing devices are generally arranged inside the brackets. Since the glass tubes are always in a fixed position of the brackets, when replenishing water to large-sized soil columns, the water pressure in the glass tubes remains constant all the time. Because the forming materials of many large-sized soil columns are different, the required water pressure is also different. When changing the water pressure, the existing water replenishing devices need to replace the glass tubes, resulting in a small applicable range of the existing water replenishing devices.

The picking and pressing magnet and the picking fixing part jointly realize the extrusion of the hose of the water replenishment connecting pipe, avoiding the outflow of seepage water inside the water replenishment pipe and the dripping of seepage water onto the laboratory floor, ensuring the cleanliness of the laboratory and facilitating the use of experimental personnel.

[0044] As shown in the Figure 1 to Figure 4 accompanying drawings:

[0045] The present utility model provides a water replenishing device for large-size soil column wet-dry cycle experiments, including a water replenishing base 1, an experimental electronic scale 2, a lifting adjustment bracket 3, a lifting limit sliding groove 4, a lifting adjustment plate 5, a water replenishing pipe 6, a water replenishing connecting pipe 7, and a water replenishing lifting mechanism;

[0049] The lifting adjustment plate 5 is slidably connected to the inner front end of the lifting limit sliding groove 4;

[0050] The water replenishing pipe 6 is placed inside the lifting adjustment bracket 3;

[0051] The water replenishing connecting pipe 7 is fixedly connected to the lower right side of the water replenishing pipe 6, and the water replenishing connecting pipe 7 is provided with a hose structure;

[0052] The water replenishing lifting mechanism is arranged outside the lifting adjustment bracket 3.

[0053] Among them, the water replenishing lifting mechanism includes: a lifting drive box 101, a lifting winding shaft 102, a lifting drive rope 103, a lifting drive handwheel 104, a lifting drive worm 105, and a lifting drive worm gear 106;

[0056] The lifting drive rope 103 is fixedly connected above the lifting adjustment plate 5, and the upper end of the lifting drive rope 103 is fixedly connected to the lifting winding shaft 102;

[0057] The lifting drive handwheel 104 is rotatably connected to the rear of the lifting drive box 101;

[0058] The lifting drive worm 105 is rotatably connected inside the lifting drive box 101, and the lifting drive worm 105 is coaxially fixedly connected to the lifting drive handwheel 104;

[0059] The lifting drive worm gear 106 is rotatably connected inside the lifting drive box 101. The lifting drive worm gear 106 meshes with the lifting drive worm 105, and the lifting drive worm gear 106 is coaxially and fixedly connected to the lifting winding shaft 102.

[0060] In use, when it is necessary to adjust the water supply pressure, rotate the lifting drive handwheel 104 at this time. The rotation of the lifting drive handwheel 104 drives the rotation of the lifting drive worm 105. The rotation of the lifting drive worm 105 drives the rotation of the lifting drive worm gear 106. The rotation of the lifting drive worm gear 106 drives the rotation of the lifting winding shaft 102. The rotation of the lifting winding shaft 102 realizes the winding of the lifting drive rope 103. At this time, the lifting drive rope 103 pulls the lifting adjustment plate 5 upward. The upward movement of the lifting adjustment plate 5 drives the water supply pipe 6 to move upward. At this time, the height difference between the water supply pipe 6 and the soil column filling pipe becomes larger, realizing the increase of the water supply pressure, realizing the adjustment of the water supply pressure, making the entire water supply device applicable to experimental environments with different water pressures, improving the applicable range of the entire water supply device, and facilitating the use of experimental personnel.

[0061] Embodiment 2:

[0062] The present utility model provides a water supply device for large-size soil column dry-wet cycle experiments.

[0069] During use, when placing the water replenishing pipe 6, at this time the water replenishing pipe 6 drives the water replenishing connecting pipe 7 to move downward above the buffer placing pad 501. At this time, the buffer placing pad 501 realizes buffering for the water replenishing pipe 6. At the same time, the taking extrusion magnet 504 is attracted by the placing trigger magnet 502 and moves downward. The taking extrusion magnet 504 no longer extrudes the hose of the water replenishing connecting pipe 7 when moving downward. At this time, the water replenishing operation can be carried out. At the same time, when picking up the water replenishing pipe 6, at this time the taking extrusion magnet 504 resets under the action of the taking connection spring 505. The taking extrusion magnet 504 and the taking fixing part 503 jointly realize extrusion of the hose of the water replenishing connecting pipe 7, avoiding the outflow of permeated water inside the water replenishing pipe 6 and preventing the permeated water from dripping onto the laboratory floor, ensuring the cleanliness of the laboratory and facilitating the use of laboratory personnel.
