Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling devices, in particular to a layered sampling device for environmental engineering supervision. Background Art
[0002] As a branch of environmental science, environmental engineering mainly focuses on how to protect and rationally utilize natural resources. Through scientific means, environmental engineering aims to solve increasingly severe environmental problems, improve environmental quality, and promote the coordination and unity of environmental protection and social development. In environmental engineering practice, sampling devices are usually used to collect soil samples for pollution analysis and monitoring. However, the operating procedures of existing sampling devices are relatively cumbersome and require cooperation of personnel from different professions, which is not conducive to environmental protection.
[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN219890759U proposes a stratified sampling device for environmental engineering supervision. The device drives the rotating sleeve to rotate through a rotating rod, so that the threaded sleeve drives the extension rod to move downward, thereby reducing the degree of damage to the soil and better meeting the standards of environmental engineering. When the depth required for sampling is reached, the user pulls the blocking tube upward from the inside of the extension rod, so that one side of the blocking tube is away from the feed port. At this time, the soil at the specified depth is drawn from the inside of the feed port into the inside of the extension rod due to pressure, and the sampling is completed.
[0004] However, although the above-mentioned stratified sampling device for environmental engineering supervision can drive the rotating sleeve to rotate through the rotating rod, so that the threaded sleeve drives the extension rod to move downward, and then the blocking tube is pulled out upward from the inside of the extension rod to complete the sampling, when the stratified sampling device for environmental engineering supervision is used to sample harder soil, the amount of soil that is drawn into the extension rod from the feed port due to pressure is small, resulting in the problem of requiring multiple samplings. Therefore, the utility model provides a stratified sampling device for environmental engineering supervision to meet the needs. Utility Model Content

[0033] like Figures 1 to 6As shown, an embodiment of the utility model provides a stratified sampling device for environmental engineering supervision, including a support column 1, a sampling rod 6 with a drill bit 16 is movably provided inside the support column 1, a plurality of sampling chambers 7 with feed ports 13 are provided at the bottom of the sampling rod 6 along its length direction, a handle 10 is provided at the top of the sampling rod 6, two limiting grooves 9 are relatively provided along the length direction of the sampling rod 6, a limiting ring 4 for limiting the limiting groove 9 is provided on the support column 1, and a rotating block 5 is sleeved and threadedly connected to the sampling rod 6, the rotating block 5 is rotatably connected to the outer wall of the support column 1 through a bearing 17, and a handle 8 is provided on the rotating block 5.
[0034] Specifically, when sampling is needed, the support column 1 is fixed at the sampling location, the limiting ring 4 is used to limit the limiting groove 9, and then the handle 1 8 is used to drive the rotating block 5 to rotate. Since the sampling rod 6 is threadedly connected to the rotating block 5, when the rotating block 5 is rotated, the sampling rod 6 will move downward in the vertical direction, so that the sampling rod 6 and the sampling drill penetrate into the surface. After reaching the specified depth, the limiting ring 4 is removed, that is, the limiting of the limiting groove 9 is released. At this time, the handle 2 10 is turned, so that the handle 2 10 drives the sampling rod 6 to rotate, and the sampling rod 6 drives the sampling chamber 7 to rotate, so that the sampling rod 6 and the sampling drill penetrate into the surface. The user enters the sampling chamber 7 along the sampling port. After the sampling is completed, the limiting groove 9 is further limited by the limiting ring 4, and then the handle 8 is reversed to move the sampling rod 6 upward, thereby realizing the collection of multi-layer samples. The overall operation is simple, and a sufficient amount of samples can be effectively collected to avoid the need for multiple samplings, thereby improving the sampling efficiency and solving the problem that when the existing sampling device samples harder soil, the amount of soil that enters the extension rod from the feed port 13 due to pressure is small, thereby requiring multiple samplings and resulting in low sampling efficiency.
[0035] It should be noted that a movable groove 12 is provided in the support column 1 for the sampling rod 6 to move, and a through hole 20 is penetrated on the support column 1 for the limit ring 4 to pass through. The through hole 20 is connected to the movable groove 12. Furthermore, the bearing 17 can be a ball bearing, a sealed bearing, etc.
[0036] like Figure 2 and Figure 3 As shown, in the present embodiment, a receiving groove 11 for the sampling chamber 7 to enter is provided through the support column 1, the receiving groove 11 is connected to the movable groove 12, and the diameter of the receiving groove 11 is larger than the movable groove 12. Specifically, the provision of the receiving groove 11 facilitates the storage of the sampling chamber 7 and the sampling rod 6, avoids damage to the sampling chamber 7, and improves the protection of the receiving groove 11.
[0037] like Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, a through hole 14 is penetrated at one end of the sampling chamber 7 away from the feed port 13, a sealing cover 15 is provided on the sampling chamber 7 to seal the through hole 14, the sampling chamber 7 has an inclined surface 19 which is inclined downward from the through hole 14 to the feed port 13, and a side of the sampling chamber 7 has an inclined surface 18 which is inclined inward from top to bottom, and the top and bottom of the sampling chamber 7 are fixedly connected with guide grooves 21 along the length direction thereof. Specifically, when it is necessary to take out the sample in the sampling chamber 7, the sealing cover 15 is opened, and then the external high-pressure ventilation device and the ventilation are connected. The sampling chamber 7 is connected to the sampling port 14, so that the air pressure generated by the external high-pressure ventilation equipment is used to blow the sample in the sampling chamber 7 out along the sampling port, thereby realizing rapid sample collection and improving sampling efficiency. At the same time, the setting of the inclined surface 18 is convenient for the sampling chamber 7 to penetrate into the sampling soil, while the setting of the inclined surface 2 19 is convenient for the rotation of the sampling chamber 7 and for pouring the sample into the sampling chamber 7 along the sampling port. At the same time, the setting of the guide pattern 21 can facilitate the sampling chamber 7 to enter and exit the soil, reduce the friction of the sampling chamber 7 entering and exiting the soil, and further improve the sample collection efficiency.
[0038] like Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment, the limiting ring 4 is made of elastic material, specifically, the limiting ring 4 is made of spring steel, and the limiting ring 4 can be deformed by external force so that the limiting ring 4 can quickly limit the limiting groove 9. At the same time, the limiting ring 4 can be made of iron, copper, etc.; further, in order to reduce the friction between the limiting ring 4 and the limiting groove 9, the end face of the limiting ring 4 in contact with the limiting groove 9 can be set to a spherical structure, and the contact surface between the limiting groove 9 and the limiting ring 4 is a smooth surface, which is convenient for the sampling rod 6 to slide along the limiting rod. It should be noted that when the sampling rod 6 moves up and down, the limiting end of the limiting ring 4 will not slide out along the limiting groove 9 to ensure the normal implementation of the device.
[0039] like Figure 1 As shown, in the present embodiment, two fixing plates 2 are relatively fixedly connected to the bottom of the support column 1, and a plurality of fixing cones 3 are fixedly connected to the bottom of the fixing plate 2. Specifically, when the support column 1 needs to be supported, the two fixing plates 2 are brought into contact with the ground surface, and then the user applies an external force to the top of the fixing plate 2 so that the fixing cone 3 at the bottom of the fixing plate 2 is inserted into the soil. At this time, the support column 1 is limited, the stability of the support column is improved, and the operation is convenient. Furthermore, in another embodiment, the fixing plate 2 can be hinged to the support column 1, so that the user can easily store the fixing plate 2.
[0040] Working principle:
[0041] First, move the device to the designated sampling location, and then make the two fixing plates 2 contact with the ground surface. Then, the user applies external force to the top of the fixing plate 2 so that the fixing cone 3 at the bottom of the fixing plate 2 is inserted into the soil. At this time, the support column 1 is limited. At this time, the limiting ring 4 is used to limit the limiting groove 9, and the handle 1 8 is used to drive the rotating block 5 to rotate. Since the sampling rod 6 is threadedly connected with the rotating block 5, when the rotating block 5 rotates, the sampling rod 6 will move downward in the vertical direction, so that the sampling rod 6 and the sampling drill go deeper into the ground surface. After reaching the designated depth, the limiting ring 4 is removed to release the limiting groove 9. At this time, turn the handle 2 10 to make The handle 10 drives the sampling rod 6 to rotate, and the sampling rod 6 drives the sampling chamber 7 to rotate, so that the sample enters the sampling chamber 7 along the sampling port. After the sampling is completed, the limiting groove 9 is continued to be limited by the limiting ring 4, and then the handle 1 8 is reversed to move the sampling rod 6 upward, thereby realizing the collection of multi-layer samples. The overall operation is simple, and a sufficient amount of samples can be effectively collected to avoid the need for multiple samplings, thereby improving the sampling efficiency and solving the problem that when the existing sampling device samples harder soil, the amount of soil that enters the extension rod from the feed port 13 due to pressure is small, thereby requiring multiple samplings and resulting in low sampling efficiency.
