Description

Technical Field

[0001] The utility model relates to the technical field of soil collection, in particular to a columnar sample collection device for intertidal zone sediments. Background Art

[0002] The collection of intertidal sediment samples is an important preliminary basic work to understand the intertidal sediment situation and explore the sediment environmental quality. Due to the limitations of geological soil layers, there is no fixed and unified collection equipment. Usually, relatively lightweight collection devices are selected, such as collection tubes, which are inserted into underwater sediments through gravity or impact and vibration to obtain columnar samples.

[0003] During this operation, only surface samples can be collected by gravity, and deep samples can be collected by vibration. However, it is not taken into account that during the collection and removal process, the sediment particles will be rearranged, changing the original sediment structure, which will cause the original state of the sample to be different. This can easily lead to cross-contamination of sediments at different depths in the collection device, affecting the sample data at different depths. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2 The utility model provides a technical solution: a columnar sample collection device for intertidal zone sediments, comprising a control body 1 and a sampling tube 2, the sampling tube 2 is located at the bottom of the control body 1, and a shell 1 3 and a shell 2 4 are provided on the outer periphery of the sampling tube 2, and a sealing ring 5 is detachably installed on the end of the shell 1 3 and the shell 2 4 away from the control body 1, and a fixing block 6 is installed between the end of the shell 1 3 away from the sealing ring 5 and the control body 1, and the sampling tube 2 is composed of a plurality of segmented short tubes 7 connected together, and a separation component is provided at the connection nodes between the plurality of segmented short tubes 7, for separating the sediment inside the sampling tube 2, and by opening the control body 1, the sampling tube 2 can be easily driven to move downward by vibration and inserted into the sediment, so that after the sediment enters the sampling tube 2, the sediment in the sampling tube 2 can be separated by using the separation component.

[0025] Furthermore, shell 1 3 and shell 2 4 are wrapped around the outer circumference of the sampling tube 2, and shell 1 3 and shell 2 4 are clamped together by a locking block. In this embodiment, shell 1 3 and shell 2 4 are provided to wrap and protect the outer surface of the sampling tube 2 and isolate the sediment. After sampling, the sampling tube 2 can be taken out by opening shell 2 4, thereby preventing the outer surface of the sampling tube 2 from contacting the sediment during the sampling process.

[0026] See also Figure 3 and Figure 4 The present invention provides a technical solution: further, the separation component includes a positioning block 8 that is clamped and installed at the lower connection point of the segmented short tube 7, a rotating ring 9 is rotatably installed on the outer periphery of the positioning block 8, and a separation member for separating the sediment inside the sampling tube 2 is rotatably installed between the rotating ring 9 and the positioning block 8. A clamping ring 10 is provided at the bottom of the rotating ring 9, and the inside of the clamping ring 10 is installed at the upper connection point of another segmented short tube 7. A rotating member is provided between the rotating ring 9 and the shell 3 for controlling the rotation of the rotating ring 9.

[0027] Furthermore, the separation member includes a plurality of blocks 11 fixedly and slidably mounted on the bottom of the positioning block 8, and a dividing block 12 is fixedly mounted on the end of the plurality of blocks 11 away from the positioning block 8, and a limiting block 13 is fixedly mounted on the bottom of the dividing block 12. The limiting block 13 is slidably mounted on the inside of the rotating ring 9 at the end away from the dividing block 12, and a limiting groove 14 is provided on the rotating ring 9 at the sliding position of the limiting block 13. In this embodiment, the rotating member rotates to drive the fixed gear 17 engaged on the rotating gear 18 to rotate, thereby driving the limiting block 13 on the dividing block 12 inside the rotating ring 9 to rotate along the limiting groove 14, closing the opening on the rotating ring 9, thereby separating the sediment in the sampling tube 2.

[0028] Furthermore, there are six dividing blocks 12 in total, and the six dividing blocks 12 are distributed in an array with the center of the rotating ring 9 as a reference.

[0029] Furthermore, a matching clamping groove 15 is provided on the upper surface of the positioning block 8 corresponding to the installation position of the segmented short tube 7 , and a sliding groove 16 is provided on the lower surface of the positioning block 8 corresponding to the sliding position of the clamping block 11 .

[0030] Furthermore, the rotating part includes a fixed gear 17 fixedly mounted on the outer periphery of the rotating ring 9, a rotating gear 18 is meshed with the surface of the fixed gear 17, a rotating rod 19 is fixedly mounted in the middle of the rotating gear 18, and a driving motor is provided at the end of the rotating rod 19 to drive the rotating rod 19 to rotate. This technology is very common and is therefore not described in the claims.

[0031] Furthermore, the rotating rod 19 is located on one side of the fixed gear 17, and the rotating rod 19 is rotatably installed inside the housing 1 3.

[0032] Working principle: When the columnar sample collection device for intertidal sediment is in use, the sampling tube 2 can be easily driven downward by vibration by turning on the control body 1 and inserted into the sediment. After the sediment enters the sampling tube 2, the rotating gear 18 can be driven to rotate by controlling the rotation rod 19, and the fixed gear 17 engaged on the rotating gear 18 can be driven to rotate, thereby driving the limit block 13 on the dividing block 12 inside the rotating ring 9 to rotate along the limit groove 14, closing the opening on the rotating ring 9, thereby separating the sediment in the sampling tube 2, and then the sampling tube 2 can be taken out. This method can prevent the sediment from being disturbed by external forces during the extraction process, allowing the sediment to form a stable environment in the sampling tube 2, and preventing the sampling tube 2 from being cross-contaminated or displaced due to vibration or external influences during the process of being taken out of the intertidal zone, thereby affecting the representativeness and accuracy of the sample.

[0033] It is worth mentioning that, considering that sediment sampling is usually multi-point collection, the outer surface of the sampling tube 2 needs to be cleaned during the sampling process to prevent the outer surface of the sampling tube 2 from contacting with previous sediments during the sampling process and thus affecting the sample. However, it is not taken into account that some sediments have strong adhesion and cannot be simply cleaned. Therefore, the outer surface of the sampling tube 2 is wrapped and protected by providing shell 1 3 and shell 2 4 to isolate the sediment. After sampling, the sampling tube 2 can be taken out by opening shell 2 4. This can prevent the outer surface of the sampling tube 2 from contacting with the sediment during the sampling process, further ensuring the purity of the sample.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the conventional means mature in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
