Description

Technical Field

[0001] The utility model relates to the technical field of ecological environment detection, in particular to a sampling device for wetland ecological environment detection. Background Technique

[0002] As a special type of ecosystem that transitions between land and water, wetlands, together with forests and oceans, are known as the world's three major ecosystems. Although the wetland area only accounts for 4% - 6% of the global area, the carbon storage in the wetland ecosystem accounts for 12% - 24% of the global terrestrial carbon storage. The relatively high productivity level and special reducing environment in the wetland ecosystem enable the wetland to exhibit the function of carbon sink during the carbon storage process. With the in-depth study of the driving mechanisms of global change, wetlands, as important carbon sources or carbon sinks, have been increasingly emphasized and have become one of the research hotspots and key contents in wetland science. Therefore, a sampling device for wetland ecological environment detection will be used;

[0003] For example, a sampling device for wetland ecological environment detection disclosed in Chinese Patent CN217237293U samples soil through a baffle. However, when the baffle is pushed by the soil and rotates upward, the baffle will be in a vertical position. Therefore, after moving the sampling tube upward, it is very difficult to make the baffle rotate downward, and it is thus very difficult to take out the soil in the sampling tube, which will affect the sampling of the soil by the sampling device;

[0004] However, there are certain defects in this patent. Although the device can collect soil through a sampling box, the soil collected each time is from the upper layer. It is difficult for the operator to collect soil at different depths as needed, resulting in certain limitations when using this device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sampling device for wetland ecological environment detection to achieve the purpose of solving the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A sampling device for wetland ecological environment detection, including a fixing plate,

[0007] A connecting block is fixedly installed on the side wall of the fixing plate;

[0008] And a sampling assembly is installed at the bottom position of the fixing plate;

[0009] The sampling assembly includes a sampling mechanism installed at the bottom position of the fixing plate;

[0010] A support mechanism is installed at the bottom position of the fixing plate, and the support mechanism is located on the side of the sampling mechanism.

[0011] Preferably, there are three connecting blocks, the shapes and sizes of the three connecting blocks are equal, and the three connecting blocks are evenly distributed on the side of the fixing plate.

[0012] Preferably, a threaded rod is installed on the inner wall of the fixing plate, a turntable is fixedly installed at the top of the threaded rod, and a sampling block is fixedly installed at the bottom of the threaded rod. The height of the sampling block can be adjusted by the threaded rod.

[0013] Preferably, the sampling mechanism includes a cylinder, the cylinder is fixedly installed on the inner wall of the sampling block, a telescopic rod is installed on the output end of the cylinder in a transmission manner, a moving block is fixedly installed at the other end of the telescopic rod, a hinge rod is installed at the inner wall of the moving block in a hinge manner, the other end of the hinge rod is installed at a displacement block in a hinge manner, and a sampling cylinder is fixedly installed on the side wall of the displacement block.

[0014] Preferably, a collection hole is formed in the inner wall of the sampling cylinder, and the side wall of the sampling cylinder is slidably connected with the inner wall of the sampling block. The collected soil will enter the inner wall of the collection hole.

[0015] Preferably, the support mechanism includes a socket block, one end of the socket block is installed on the side wall of the connecting block in a hinge manner, a plug rod is fixedly installed on the socket block through a positioning bolt, and the other end of the plug rod is installed on a connecting plate in a hinge manner.

[0016] Preferably, a pointed block is fixedly installed at the bottom of the connecting plate, and the side wall of the plug rod is slidably connected with the inner wall of the socket block.

[0017] The utility model provides a sampling device for wetland ecological environment detection. It has the following beneficial effects:

[0018] (1). In the utility model, the operator directly rotates the position of the turntable, and the turntable drives the position of the threaded rod to rotate. Since the side wall of the threaded rod is threadedly connected with the inner wall of the fixing plate, when the threaded rod rotates, it can drive the position of the sampling block to descend. When the sampling block enters the appropriate depth of the soil, the cylinder can be directly opened. The cylinder drives the position of the moving block to descend through the telescopic rod, and the moving block will squeeze one end of the hinge rod. The hinge rod drives the sampling cylinder to slide on the inner wall of the sampling block, and the soil is sampled through the sampling cylinder, and the soil will enter the inner wall of the sampling cylinder, realizing rapid sampling, and solving the problem that although the existing device can collect soil through the sampling box, the soil collected each time is from the upper layer, and it is difficult for the operator to collect soil at different depths as needed, resulting in certain limitations in the use of the device.

[0019] (2) When the operator rotates the position of the positioning bolt and one end of the positioning bolt disengages from the inner wall of the insertion rod, the position of the insertion rod can be directly slid. When the fixing plate is adjusted to the appropriate height, the positioning bolt is rotated again to cause one end of the positioning bolt to limit the position of the insertion rod. Subsequently, the device is stabilized by the pointed block inserted into the soil, facilitating the operator to better use the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] During the specific implementation process, the operator directly rotates the position of the turntable 5, and the turntable 5 drives the position of the threaded rod 3 to rotate. Since the side wall of the threaded rod 3 is threadedly connected to the inner wall of the fixed plate 1, when the threaded rod 3 rotates, it can drive the position of the sampling block 6 to descend. When the sampling block 6 reaches an appropriate depth in the soil, the cylinder 411 can be directly opened.
