Description

Technical Field

[0001] The utility model relates to the field of soil penetration, in particular to a soil penetration measuring device. Background Art

[0002] Soil infiltration, also known as soil water permeability, refers to the ability of soil to penetrate surface water. Soil permeability is of great significance to agriculture, water conservancy, environmental engineering and other fields. For example, in agriculture, reasonable irrigation and drainage design needs to consider soil permeability to avoid excessive or insufficient water on crop growth. In water conservancy projects, the study of soil permeability helps to predict and control the seepage conditions of water conservancy projects such as reservoirs and embankments to ensure project safety. Soil infiltration measurement devices simulate natural precipitation or irrigation conditions to measure the saturated and unsaturated hydraulic conductivity of the soil, thereby evaluating the permeability of the soil. These devices usually include key components such as sample chambers, head control systems, flow measurement systems and head loss measurement systems, which work together to accurately measure the permeability of the soil under different hydraulic gradients.

[0003] After searching, a soil permeability measuring device with publication number CN220170811U specifically discloses a soil permeability measuring device, in which a bracket is fixedly connected to the outer side of the base, and there are two brackets in total, and the two brackets are fixedly connected to the outer positions of the left and right sides of the base respectively, so as to solve the problem that the existing device lacks an effective metering structure, which causes inaccurate measurement data during measurement and has limitations. When permeability testing is required, the test tube can be inserted into the limit seats on the inner sides of the two support frames, and the bottom end of the test tube can be docked with the soil located in the support seat, and then the liquid to be tested is poured into the internal position of the test tube. At this time, the timer is started externally to count, and the penetration of the liquid in the test tube within the specified time is observed, and the scale set at the front end of the test tube is used to observe and judge the penetration of the liquid in the current test tube, thereby achieving a more practical purpose.

[0004] During use, the existing soil permeability measuring device has different soil permeability measurement methods. If the soil permeability measuring device only has one directional water injection permeation method, it cannot fully reflect the overall permeability performance of the soil under extensive and uniform precipitation or irrigation conditions. This limitation will lead to an incomplete and inaccurate assessment of the soil permeability performance. In addition, the soil permeability measuring device in the above-mentioned comparative case also lacks other permeability measurement methods. Therefore, the long-term use of a single permeability measurement method cannot guarantee the accuracy and reliability of the test results.

[0005] Therefore, it is necessary to invent a soil permeability measuring device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a soil infiltration measuring device, which realizes two different infiltration measurement modes through the infiltration chamber cover, the spray chamber, the spray nozzle, the directional infiltration cylinder, the spray cylinder and the pressurized water pump. One is to spray water evenly through the multiple groups of spray nozzles inside the infiltration chamber cover to simulate rainfall or irrigation process. The other is to insert the directional infiltration cylinder through the directional seat to allow the water in the directional infiltration cylinder to penetrate into the soil in one direction to simulate the water infiltration under specific conditions. In this way, the soil infiltration measuring device can perform both uniform water spraying simulation and directional infiltration simulation to meet different soil experimental needs. Such measurement data can not only comprehensively reflect the soil in a wide range, but also can fully reflect the soil in a wide range. The overall permeability performance under conditions of widespread and uniform precipitation or irrigation is not only measured by different methods, but also the accuracy and reliability of the test results are guaranteed to solve the problem that the soil permeability measuring device in the prior art cannot fully reflect the overall permeability performance of the soil under conditions of widespread and uniform precipitation or irrigation due to different soil permeability measurement methods. If the soil permeability measuring device only has one directional water injection permeation method, it will not be able to fully reflect the overall permeability performance of the soil under conditions of widespread and uniform precipitation or irrigation. This limitation will lead to an incomplete and inaccurate evaluation of the soil permeability performance. The soil permeability measuring device in the above-mentioned comparative case also lacks other permeability measurement methods. Therefore, under long-term use, a single permeability measurement method cannot guarantee the accuracy and reliability of the test results.

[0017] 1. The utility model is provided with a permeation chamber cover, a spraying chamber, a spraying nozzle, a directional permeation cylinder, a spraying cylinder and a pressurized water pump.

In this way, the soil infiltration measurement device can perform both uniform water spray simulation and directional infiltration simulation to meet different soil experimental needs.

[0018] 2. The utility model is provided with a permeability cavity, a permeability sensor, an external display controller, a permeability cavity cover, fastening bolts and a sealing ring.

The sealing ring also strengthens the sealing ability of the closing part. At the same time, during the permeability measurement process, the permeability sensor inside the permeability cavity can also transmit the current permeability measurement data directly to the external display controller through the connecting line, so as to facilitate the external operator to record it in time.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The utility model provides Figure 1-5 A soil permeability measurement device shown includes a permeability measurement body 1, which is a main body for performing soil permeability measurement;

[0029] The infiltration chamber 2 is arranged above the infiltration measurement body 1 and is used to place different types of soil. A fixing bolt 9 is passed through the outside of the infiltration measurement body 1. One end of the fixing bolt 9 is movably connected to a penetration frame 10. A sliding groove 11 is provided inside the infiltration frame 10. A sliding block 12 is movably connected inside the sliding groove 11. A support plate 13 is fixedly installed at one end of the sliding block 12. A permeation chamber cover 14 is fixedly installed on the outside of the support plate 13.

[0030] A directional seat 16 is provided above the permeation chamber cover 14 and is used for directional water injection and permeation. A directional permeation tube 17 is fixedly mounted on the bottom of the directional seat 16. A spray chamber 20 is fixedly mounted inside the permeation chamber cover 14. A spray nozzle 21 is provided at the bottom of the spray chamber 20, and a liquid inlet 22 is provided above the spray chamber 20.

[0031] A directional infiltration cylinder 23 is arranged inside the directional seat 16 and is used to carry the liquid used for directional infiltration. A first scale line 24 is provided on the outside of the directional infiltration cylinder 23. A spraying cylinder 25 is fixedly installed on the top of the infiltration frame 10. A second scale line 26 is provided on the outside of the spraying cylinder 25. A pressurized water pump 27 is provided under the spraying cylinder 25. Depending on the type of soil currently being measured and the infiltration measurement method required for soil infiltration, the pressurized water pump 27 can first extract the liquid in the spraying cylinder 25, and then inject it into the spray cavity 20 to be sprayed out by the spray nozzle 21, or the directional infiltration cylinder 23 can be directly inserted into the directional seat 16 above the infiltration cavity cover 14, so that the liquid inside the directional infiltration cylinder 23 can be directionally infiltrated into the soil below along the directional infiltration tube 17.

[0032] like Figure 1 、 Figure 2 and Figure 3As shown, a permeability sensor 3 is fixedly installed inside the permeability measuring body 1, a seepage tube 4 is fixedly installed at the bottom of the permeability sensor 3, an external display controller 5 is fixedly installed outside the permeability measuring body 1, and the permeability sensor 3 inside the permeability cavity 2 can also directly transmit the current permeability measurement data to the external display controller 5 through a connecting line, so as to facilitate the external operator to record it in time. A support frame 6 is fixedly installed at the bottom of the permeability measuring body 1, a liquid receiving cylinder 7 is fixedly installed inside the support frame 6, and an external scale 8 is provided on the outside of the liquid receiving cylinder 7. The liquid receiving cylinder 7 and the external scale 8 can count the amount of liquid that permeates from the inside of the permeation cavity 2, so as to facilitate the calculation of soil permeability measurement data. The permeability cavity cover 14 is slidably connected to the permeation frame 10, and the sliding groove 11 is used in conjunction with the sliding block 12. The structure of the sliding groove 11 and the sliding block 12 is simple and easy to operate. If a fault occurs, it is also convenient for maintenance personnel to replace or repair it in time.

[0033] like Figure 1 、 Figure 4 and Figure 5 As shown, a telescopic cylinder 15 is fixedly installed above the infiltration chamber cover 14, and a fastening bolt 18 passes through the inside of the infiltration chamber cover 14. One end of the fastening bolt 18 is movably connected to a sealing ring 19. Due to the closing of the infiltration chamber 2 and the infiltration chamber cover 14, the entire infiltration measurement space forms a relatively closed environment, which reduces the interference of external factors on the experimental process and improves the reliability of the experiment. In addition, the sealing ring 19 also strengthens the sealing ability of the closing point. The number of spray nozzles 21 is set to multiple, and the multiple spray nozzles 21 are evenly spaced on the spray chamber 20. Water is evenly sprayed through the multiple groups of spray nozzles 21 inside the infiltration chamber cover 14 to simulate rainfall or irrigation process.

[0034] The working principle of the present invention is as follows: first, connect the external power supply, take out the sampled soil, and spread the soil flatly inside the infiltration chamber 2, then turn on the switch of the telescopic cylinder 15, let the telescopic cylinder 15 expand and contract, and drive the infiltration chamber cover 14 to close the infiltration chamber 2 through the sliding groove 11 and the sliding block 12. Due to the closing of the infiltration chamber 2 and the infiltration chamber cover 14, the entire infiltration measurement space forms a relatively closed environment, which reduces the interference of external factors on the experimental process and improves the reliability of the experiment. In addition, the sealing ring 19 also strengthens the sealing ability of the closing part. Then, according to the current measurement Depending on the type of soil and the infiltration measurement method required for soil infiltration, the pressurized water pump 27 can be used to extract the liquid in the spray barrel 25, and then inject it into the spray cavity 20 and spray it out from the spray nozzle 21. In this way, water is evenly sprayed through the multiple groups of spray nozzles 21 inside the infiltration cavity cover 14 to simulate rainfall or irrigation. Subsequently, a directional infiltration cylinder 23 can be inserted directly into the directional seat 16 above the infiltration cavity cover 14 to allow the liquid inside the directional infiltration cylinder 23 to directionally infiltrate the soil below along the directional infiltration pipe 17. In this way, the directional infiltration cylinder 23 is inserted into the directional seat 16 to allow the directional infiltration cylinder 23 to penetrate the soil below. Water in the permeability tube 23 penetrates the soil in one direction, simulating water infiltration under specific conditions. This allows the soil permeability measurement device to have two different permeability measurement modes to meet different soil experimental requirements. Such measurement data can not only comprehensively reflect the overall permeability performance of the soil under extensive and uniform precipitation or irrigation conditions, but also ensure the accuracy and reliability of the test results. Then, during the permeability measurement process, the permeability sensor 3 inside the permeability chamber 2 can also directly transmit the current permeability measurement data to the external display controller 5 via a connecting line, thereby facilitating timely recording by external operators. Then, the liquid sprayed into the permeability chamber 2 will penetrate the soil and then flow from the seepage pipe 4 into the liquid receiving tube 7 below. The liquid receiving tube 7 and the external scale 8 can count the amount of liquid that permeates from the permeability chamber 2, thereby facilitating the calculation of soil permeability measurement data. Finally, after completing the installation and use of the soil permeability measurement device according to the above operations, turn off the switch of the telescopic cylinder 15 and the switch of the pressurized water pump 27. If not in use for a long time, disconnect the external power supply. In this way, the use process of the soil permeability measurement device is completed.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
