Description

Technical Field

[0001] The utility model relates to the technical field of environmental sampling, in particular to a wetland environmental sampling auxiliary tool. Background Art

[0002] Wetlands are important water conservation areas in nature, capable of storing and regulating large amounts of water resources. In the dry season, wetlands can provide humid climate conditions for the surrounding areas through evaporation; in the rainy season, wetlands can absorb excess rainwater like a sponge, reducing the occurrence of floods and waterlogging disasters. This regulatory effect on climate and water resources is crucial to maintaining the ecological balance of the region. Wetlands also provide a living environment for many rare and endangered animal and plant species, so the management and protection of wetland environments have far-reaching significance. In the process of managing the wetland environment, soil sampling is required, and then the collected soil is tested to formulate management directions and plans.

[0003] For example, the Chinese utility model patent with patent number 201821238298.X provides a wetland soil sampler, which includes a cylinder and a ring knife. The ring knife is inserted into the ground for sampling, and the soil sample can be frozen by using a low-temperature refrigerant, which can not only prevent the soil sample from slipping out of the sampling cylinder, but also prevent the soil from flowing and mixing when the soil sample is taken out of the sampling cylinder. However, when the existing sampling tools for wetland environments are used to sample soil with a high water content, the water in the soil is easily lost in large quantities, thereby affecting the test results. Therefore, in view of this, a wetland environment sampling auxiliary tool is proposed to solve the above technical problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model proposes a wetland environment sampling auxiliary tool to solve the technical problem that when the existing sampling tools for wetland environments proposed in the above background technology are used to sample soil with a high water content, a large amount of water in the soil is easily lost, thereby affecting the detection results.

[0005] To achieve the above purpose, the utility model provides the following technical solution, a wetland environment sampling auxiliary tool, including:

[0006] A rod body, wherein a mounting tube is arranged on the rod body, and a soil breaking cone is arranged at the bottom of the rod body;

[0007] A mounting rod slidably disposed in the mounting tube along its axis;

[0008] A sampling cylinder is detachably disposed at the end of the mounting rod and slidably disposed in the mounting cylinder; and

[0009] The shielding cover is hinged inside the opening at one end of the sampling cylinder. A torsion spring is provided at the hinge point, and it can rotate and open or close inside the sampling cylinder to selectively shield the opening at the end of the sampling cylinder.

[0010] In a preferred embodiment, a first handle is provided on the rod body, and a second handle is provided on the mounting rod.

[0011] In a preferred embodiment, the ends of the mounting cylinder and the sampling cylinder are both inclined planes.

[0012] In a preferred embodiment, a sealing strip is provided at the edge of the shielding cover, and when the shielding cover is closed, the sealing strip fits against the inner wall of the sampling cylinder.

[0013] In a preferred embodiment, a clamping groove is formed on one side of the end of the mounting rod facing the rod body. A clamping block is provided on the sampling cylinder, and the clamping block is clamped in the clamping groove and fits against the inner wall of the mounting cylinder. A groove is formed on one side of the rod body.

[0014] In a preferred embodiment, an arc surface is provided on the abutting surface between the mounting rod and the sampling cylinder.

[0015] In a preferred embodiment, an object-taking groove is formed on the side wall of the sampling cylinder, and a detachable baffle is provided in the object-taking groove.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] When using this sampling auxiliary tool, the sampling cylinder is installed inside the mounting cylinder, and the whole device is inserted downward into the wetland soil. The soil is broken by the earth-breaking cone, so that it is more labor-saving when inserting the tool into the ground. And during the process of inserting the tool, the soil enters the sampling cylinder for sampling work. After sampling, the rod body and the mounting rod are lifted upward simultaneously, driving the sampling cylinder to move upward. During the upward movement of the sampling cylinder, the soil inside it has a tendency to move downward, and under the cooperation of the torsion spring, the shielding cover rotates and closes to hermetically shield the opening of the sampling cylinder. And the shielding cover will not automatically open after the sampling cylinder is disassembled, thus effectively preventing a large amount of water in the soil from losing during the sampling process and affecting the subsequent test results.

[0027] Hereinafter, embodiments of the technical solution of the present utility model will be described in detail with reference to the drawings. The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, and thus are only examples and cannot be used to limit the protection scope of the present utility model.

[0028] Embodiment:

[0029] As Figure 1 , 2 , shown in FIGS. 3, the present utility model provides an auxiliary tool for wetland environment sampling, including a rod body 101, a mounting cylinder 103 is arranged on the rod body 101, an earth-breaking cone 104 is arranged at the bottom of the rod body 101, a mounting rod 201 is slidably arranged along its axis in the mounting cylinder 103, a sampling cylinder 301 is arranged at the end of the mounting rod 201, the sampling cylinder 301 is slidably arranged in the mounting cylinder 103, a shielding cover 302 is hinged in the opening at one end of the sampling cylinder 301, a torsion spring is arranged at the hinge point of the shielding cover 302, and it can rotate and open and close in the sampling cylinder 301 to selectively shield the opening at the end of the sampling cylinder 301.

[0030] And a first handle 102 is provided on the rod body 101, and a second handle 202 is provided on the mounting rod 201. When in use, the whole tool can be inserted into the soil by pressing down the first handle 102. The top of the mounting rod 201 is limited by the first handle 102 and cannot move, so as to drive the mounting cylinder 103 to be inserted into the soil for sampling work. Since the ends of both the mounting cylinder 103 and the sampling cylinder 301 are inclined surfaces, the soil is broken by the earth-breaking cone 104, and the inclined surfaces at the ends of the mounting cylinder 103 and the sampling cylinder 301 are used to reduce the force required for the tool to insert into the soil, and the soil enters the sampling cylinder 301 during the insertion process for sampling work.

[0031] After sampling is completed, the second handle 202 can be pulled upward to drive the sampling cylinder 301 to move upward. The soil in the sampling cylinder 301 moves downward under its own gravity, and then cooperates with the torsion spring to drive the shielding cover 302 to close. And a sealing strip 303 is provided at the edge of the shielding cover 302. When the shielding cover 302 is closed, the sealing strip 303 fits with the inner wall of the sampling cylinder 301 to seal the opening of the sampling cylinder 301, so as to effectively prevent the water in the sampling cylinder 301 from flowing out, so that the detection data is more accurate and persuasive when detecting the obtained soil sample.

[0032] In some embodiments, the lengths of the mounting cylinder 103 and the sampling cylinder 301 can be set to 40 cm to facilitate sampling at a depth of 0-40 cm underground. In addition, in some other embodiments, the lengths of the mounting cylinder 103 and the sampling cylinder 301 can be set to 80 cm to facilitate sampling at a depth of 0-80 cm underground. Select a tool with a suitable size for use according to the specific situation.

[0033] Such as Figure 2 、 3 As shown in FIGS. 4, in this embodiment, the sampling cylinder 301 is detachably arranged at the end of the mounting rod 201. A clamping groove 203 is formed on one side of the end of the mounting rod 201 facing the rod body 101. A clamping block 306 is provided on the sampling cylinder 301. The clamping block 306 is clamped in the clamping groove 203 and fits with the inner wall of the mounting cylinder 103. A groove 105 is formed on one side of the rod body 101. The abutting surface between the mounting rod 201 and the sampling cylinder 301 is provided with an arc surface 204.

[0034] After sampling and removing the tool from the soil, the second handle 202 can be pressed downward to move the sampling barrel 301 downward to the opening of the mounting barrel 103, and then the sampling barrel 301 is rotated in the direction away from the rod body 101 along the connection between the sampling barrel 301 and the mounting rod 201, and the sampling barrel 301 moves along the arc surface 204, so that the clamping block 306 can be disengaged from the clamping groove 203, so as to disassemble the sampling barrel 301. This installation method can prevent the sampling barrel 301 from automatically falling off after the mounting rod 201 slides downward, and it is more convenient to disassemble the sampling barrel 301.

[0035] like Figure 2 , 3 As shown, in this embodiment, a sampling groove 304 is provided on the side wall of the sampling barrel 301, and a detachable baffle 305 is provided in the sampling groove 304. After the sampling barrel 301 is disassembled, the baffle 305 can be disassembled, so that the soil in the sampling barrel 301 can be easily taken out, and the moisture in the soil can be well preserved during the whole sampling process.

[0036] Specific usage and beneficial effects of the utility model:

[0037] When the sampling auxiliary tool is used, the sampling tube 301 is installed in the installation tube 103, and the device is inserted downward into the wetland soil as a whole, and the soil is broken by the soil breaking cone 104, so that the tool is more labor-saving when inserted into the ground, and during the insertion of the tool, the soil enters the sampling tube 301 for sampling. After the sampling is completed, the rod body 101 and the installation rod 201 are lifted upward at the same time, driving the sampling tube 301 to move upward. During the upward movement of the sampling tube 301, the soil inside the sampling tube 301 has a tendency to move downward, and under the cooperation of the torsion spring, the shielding cover 302 is rotated and closed to seal the opening of the sampling tube 301, and the shielding cover 302 will not open automatically after the sampling tube 301 is disassembled, thereby effectively preventing a large amount of water in the soil from being lost during the sampling process, which affects the subsequent detection results.

[0038] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
