Description

Technical Field

[0001] The utility model relates to the field of simulating the rise and fall of the groundwater level, in particular to a device for simulating the rise and fall of the groundwater level in soil. Background Technique

[0002] Groundwater refers to the water stored in the rock voids below the ground surface. Narrowly speaking, it refers to the water in the saturated aquifer below the groundwater table. In the national standard "Hydrogeological Terms" (GB / T 14157-93), groundwater refers to the gravity water in various forms buried below the ground surface. Groundwater is an important part of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industrial and mining, and cities. However, under certain conditions, the change of groundwater will also cause adverse natural phenomena such as swampification, salinization, landslides, and land subsidence;

[0003] At present, in order to understand the groundwater level in soil, a water level rise and fall simulation device is used to simulate the rise and fall of the groundwater level. The water level rise and fall can be simulated through the drainage holes that can be opened on the outer barrel, inner barrel, and soil column. However, when using the above device, it is difficult to keep the center alignment when the inner barrel is installed in the outer barrel and needs to be corrected, which affects the installation. Moreover, when there is a large amount of water in the outer barrel, it is easy to cause the inner barrel and the soil column to float upward, thus affecting the detection of the water level rise and fall. For this reason, we propose a device for simulating the rise and fall of the groundwater level in soil. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for simulating the rise and fall of the groundwater level in soil.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for simulating the rise and fall of the groundwater level in soil, including an outer barrel, an inner barrel, and a cylindrical soil column. The upper end of the outer barrel is open. The inner barrel is detachably installed in the outer barrel. The cylindrical soil column is fixedly arranged in the inner barrel. A floating prevention mechanism for pressing down the cylindrical soil column and the inner barrel is arranged on the upper side of the outer barrel. A plurality of U-shaped frames evenly distributed in a ring are fixedly arranged at the lower end of the outer circumferential side wall of the inner barrel. A pulley is rotatably arranged in each U-shaped frame through a first rotating shaft. A plurality of pulleys are in contact with and roll on the inner circumferential side wall of the outer barrel.

A vertically arranged water supply pipe is fixedly arranged on the left side of the inner circumferential side wall of the outer barrel. A vertically arranged water level observation scale is arranged on the left outer side wall of the outer barrel.

A clamping component is arranged between the right end of the rotating plate and the second fixing block and can be clamped with each other through the clamping component. The two pressing blocks are both fixedly arranged on the lower side of the rotating plate and are symmetrically distributed left and right. The lower end of each pressing block abuts against the upper surface of the cylindrical soil column and is slidably arranged.

The fixed end of the elastic telescopic rod is fixedly embedded in the second fixing block, and a clamping hole for the elastic telescopic rod to slide and insert is formed in the right end of the lower side of the rotating plate.

[0008] As a further solution of the utility model: the outer radius of the inner barrel is 25 cm, the inner radius of the outer barrel is 35 cm, and the height of the inner barrel and the depth of the outer barrel are both 80 cm.

[0011] As a further solution of the utility model: the number of the U-shaped frames and the pulleys is both set to three. The three U-shaped frames and the three pulleys are evenly distributed in a ring around the inner barrel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model.

[0023] In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please refer to the attached Figure 1 - attached Figure 5, a soil groundwater level rising and falling simulation device of the present utility model, comprising an outer barrel 1, an inner barrel 2 and a cylindrical soil column 3. The upper end of the outer barrel 1 is open. The inner barrel 2 is detachably disposed in the outer barrel 1, and the cylindrical soil column 3 is fixedly disposed in the inner barrel 2. A floating prevention mechanism for pressing down on the cylindrical soil column 3 and the inner barrel 2 is provided on the upper side of the outer barrel 1. A plurality of U-shaped frames 4 evenly distributed in a ring are fixedly disposed at the lower end of the outer circumferential side wall of the inner barrel 2. A pulley 5 is rotatably disposed in each U-shaped frame 4 through a first rotating shaft. A plurality of pulleys 5 are in contact with and roll on the inner circumferential side wall of the outer barrel 1. A plurality of first drainage holes 6 arranged vertically are opened on the right side wall of the outer barrel 1. A plurality of groups of second drainage holes 7 arranged vertically are opened on the circumferential side wall of the inner barrel 2. Each group of a plurality of second drainage holes 7 is evenly distributed in a ring around the outer circumference of the inner barrel 2. A vertically disposed water supply pipe 8 is fixedly disposed on the left side of the inner circumferential side wall of the outer barrel 1. A vertically disposed water level observation scale 9 is provided on the left outer side wall of the outer barrel 1.

[0025] In an embodiment of the present utility model: the floating prevention structure includes a first fixing block 10, a second fixing block 11, a rotating plate 12 and two pressing blocks 13. The first fixing block 10 and the second fixing block 11 are respectively fixedly connected to the upper ends of the left and right sides of the outer barrel 1. The rotating plate 12 is horizontally disposed above the outer barrel 1, and the lower left end of the rotating plate 12 is fixedly connected to the upper end of the first fixing block 10 through a second rotating shaft. A clamping component is provided between the right end of the rotating plate 12 and the second fixing block 11 and they can be clamped to each other through the clamping component. The two pressing blocks 13 are both fixedly disposed on the lower side of the rotating plate 12 and are symmetrically distributed left and right. The lower end of each pressing block 13 is in contact with and slides on the upper surface of the cylindrical soil column 3.

[0026] In an embodiment of the present utility model: the clamping component includes an elastic telescopic rod 14. The fixed end of the elastic telescopic rod 14 is fixedly embedded in the second fixing block 11. A clamping hole for the elastic telescopic rod 14 to slide and insert is opened at the lower right end of the rotating plate 12. After the inner barrel 2 and the cylindrical soil column 3 are installed, the rotating plate 12 is rotated so that the rotating plate 12 is horizontally disposed above the outer barrel 1 and the inner barrel 2 until the upper end of the elastic telescopic rod 14 is inserted into the clamping hole on the rotating plate 12 to fix the rotating plate 12. At this time, the two pressing blocks 13 on the lower side of the rotating plate 12 will downwardly press against the upper side of the cylindrical soil column 3, thereby being able to prevent the inner barrel 2 and the cylindrical soil column 3 from floating upward and avoid affecting the simulation of the water level rise and fall. When it is necessary to remove the inner barrel 2 and the cylindrical soil column 3, the mobile end of the elastic telescopic rod 14 can be downwardly pressed, so that the rotating plate 12 can be rotated and moved away, and then it is convenient to remove the inner barrel 2 and the cylindrical soil column 3.

[0027] In an embodiment of the present utility model: the outer radius of the inner barrel 2 is 25 cm, the inner radius of the outer barrel 1 is 35 cm, and the height of the inner barrel 2 and the depth of the outer barrel 1 are both 80 cm.

[0028] In an embodiment of the present utility model: the number of the first drain holes 6 is set to three, the distance between two adjacent second drain holes 7 is 20 cm, and the distance between the uppermost second drain hole 7 and the upper surface of the outer barrel 1 is 20 cm.

[0029] In an embodiment of the present utility model: a funnel-shaped water replenishing port 15 is fixedly arranged at the upper end of the water replenishing pipe 8, which is convenient for water replenishment.

[0030] In an embodiment of the present utility model: the number of the U-shaped frames 4 and the pulleys 5 is both set to three, and the three U-shaped frames 4 and the three pulleys 5 are evenly distributed in a ring around the inner barrel 2. When the inner barrel 2 and the cylindrical soil column 3 are placed into the outer barrel 1, the center line of the inner barrel 2 and the center line of the outer barrel can be vertically aligned, so that the inner barrel 2 is located in the middle of the inner part of the outer barrel 1.

[0031] Working principle:

[0032] First of all, through the arranged multiple U-shaped frames 4 and multiple pulleys 5, when the inner barrel 2 and the cylindrical soil column 3 are installed into the outer barrel 1, the multiple pulleys 5 will abut against the inner circular side wall of the outer barrel 1, and as the inner barrel 2 and the cylindrical soil column 3 move downward, the multiple pulleys 5 will roll downward on the inner circular side wall. And through the U-shaped frames 4 and the multiple pulleys 5, the center line of the inner barrel 2 can be aligned with the center line of the outer barrel 1, avoiding the deviation during the installation of the inner barrel 2 and the cylindrical soil column 3. After the inner barrel 2 and the cylindrical soil column 3 are installed, the rotating plate 12 is rotated to make the rotating plate 12 horizontally arranged above the outer barrel 1 and the inner barrel 2 until the upper end of the elastic telescopic rod 14 is inserted into the card hole on the rotating plate 12 to fix the rotating plate 12. At this time, the two pressing blocks 13 on the lower side of the rotating plate 12 will press downward against the upper side of the cylindrical soil column 3, so as to avoid the upward floating of the inner barrel 2 and the cylindrical soil column 3 and avoid affecting the simulation of the water level rise and fall. So far, the whole working process is completed.
