Description

Technical Field

[0001] This utility model relates to a seepage rate detection device, specifically a soil seepage rate detection device for water conservancy surveying, belonging to the field of soil testing technology. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They include various types of projects such as flood control, irrigation, drainage, hydropower generation, waterway management, port engineering, urban water supply and drainage, soil and water conservation, and water resource protection. Before the construction of water conservancy projects, it is necessary to test the land environment of the construction site to test whether the infiltration rate of the original soil layer meets the relevant requirements.

[0003] Common methods for detecting water infiltration rate typically involve inserting a detection device directly into the soil within a designated area, then continuously watering the soil surface to simulate rainfall. Once the water has seeped into the soil, the readings on the detection device are observed. A change in the data indicates that water has infiltrated to the location of the detection device. By recording the data and time detected by the device at this point, the soil infiltration rate of the environment can be calculated.

[0004] The above method has certain drawbacks when testing soil infiltration rate. Although the water poured on the soil surface naturally seeps into the soil, it does not obstruct the soil where the test is being conducted. As the water seeps downward, it may deviate and not penetrate to the location of the testing device, which may lead to errors in the test.

[0005] Therefore, a soil seepage rate detection device for water conservancy survey is proposed here. Utility Model Content

[0006] This invention proposes a soil seepage rate detection device for water conservancy surveying, in order to solve the problem of detection errors that occur when existing detection devices are directly inserted into the soil for detection.

The bottom cylinder includes a first cylinder body with a groove at the top of the first cylinder body. The extension cylinder includes a second cylinder body with a protrusion corresponding to the groove fixed at the bottom end of the second cylinder body. The protrusion engages with the groove. A slot is provided at the top of the second cylinder body. The top cover includes a top plate with a locking block corresponding to the slot fixed on the outer surface of the top plate. The size of the locking block is the same as the size of the protrusion. The locking block engages with the slot. A connecting groove is provided on the upper surface of the top plate, which can be connected to the output end of an external driving device.

[0008] The protrusion has a first limiting groove on its side, and the groove has a cavity on its side. A first limiting block is provided inside the groove cavity. The first limiting block is engaged with the first limiting groove. A first return spring is provided inside the groove cavity. One end of the first return spring is fixed to the first limiting block, and the other end of the first return spring is fixed to the first cylinder.

[0009] The inner wall of the first cylinder is provided with a first adjustment groove, which is connected to the groove chamber. A first adjustment ring is slidably connected to the inner wall of the first cylinder. The first adjustment ring is fixed to the first limiting block through the first adjustment groove. The first limiting block can be moved by pushing the first adjustment ring.

[0010] The card block has a second limiting groove on its side, and a cavity is formed on the side of the card groove. A second limiting block is provided inside the card groove cavity. The second limiting block is engaged with the second limiting groove. A second return spring is provided inside the card groove cavity. One end of the second return spring is fixed to the second limiting block, and the other end of the second return spring is fixed to the second cylinder.

[0011] The inner wall of the second cylinder is provided with a second adjustment groove, which is connected to the slot chamber. A second adjustment ring is slidably connected to the inner wall of the second cylinder. The second adjustment ring is fixed to the second limiting block through the second adjustment groove. The second limiting block can be moved by pushing the second adjustment ring.

[0012] Both the first and second cylinders have reserved grooves on their inner walls. A first reserved rod is slidably connected to the inner wall of the reserved groove of the first cylinder, and a second reserved rod is slidably connected to the inner wall of the reserved groove of the second cylinder. Both the first and second reserved rods have snap-fit ​​grooves at their top ends. A snap-fit ​​block is fixed to the bottom end of the second reserved rod. The snap-fit ​​block snaps into the snap-fit ​​groove of the first reserved rod. A cavity is formed on the side of the snap-fit ​​groove. A third limiting block is provided on the inner wall of the cavity of the snap-fit ​​groove. A third limiting groove is formed on the side of the snap-fit ​​block. The third limiting block snaps into the third limiting groove.

[0013] The outer surfaces of the first and second reserved rods are each provided with a third adjustment groove. The third adjustment groove is connected to the snap-fit ​​groove chamber. A third adjustment block is fixed to the side of the snap-fit ​​block. The third adjustment block is slidably connected to the third adjustment groove. A third return spring is installed on the side of the third adjustment block. The other end of the third return spring is fixed to the snap-fit ​​groove chamber.

[0014] This utility model provides a soil seepage rate detection device for water conservancy surveying, which has the following beneficial effects:

[0015] 1. This soil seepage rate detection device for water conservancy surveying separates the soil to be tested from the rest of the soil by inserting the bottom cylinder and the extension cylinder into the soil. This ensures that when water is poured on the upper surface of the soil to be tested, the water can only seep downwards and not laterally, eliminating the influence of lateral water seepage in the soil on the detection. This solves the problem of detection errors caused by direct insertion of detection devices into the soil in existing technologies.

[0016] 2. When using this soil seepage rate detection device for water conservancy survey, the first and second reserved rods inside the bottom cylinder and extension cylinder are pulled out, and the pin of the detection device can be inserted through the reserved groove, which facilitates the installation of the detection device. When the soil depth to which the detection device needs to be inserted is relatively deep, the overall length can be increased by adding a new extension cylinder to the top of the extension cylinder.
