Description

Technical Field

[0001] The utility model relates to the technical field of sampling device design, in particular to an intertidal zone sediment sampling device. Background Art

[0002] The intertidal zone refers to the coastal zone between the average highest tide level and the lowest tide level, and is an area where the interaction between land and sea is relatively strong. As the hydrodynamic conditions in the intertidal zone change, the suspended matter in the water body will slowly settle to form a sediment layer. In the process of sedimentary layer research (especially the carbon density of sedimentary layers), it is necessary to collect sediment samples within a certain depth below the ground in layers. Most existing technologies are based on PVC hollow tube piling and manual excavation of soil for sampling. Gravity impact is required for sampling, which is time-consuming and labor-intensive, and has the problem of severe vertical compression of samples. In addition, there is a lack of effective sealing devices to prevent the loss of sediment samples, resulting in the loss of sediment samples during the sampling process. For this reason, an intertidal sediment sampling device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See Figures 1 to 5 The embodiment of the present invention provides an intertidal zone sediment sampling device, including a main rod 3, a semi-cylinder 6 and a grooved baffle 8. A hood-shaped mounting seat 5 is provided at the bottom of the main rod 3, a semi-cylinder 6 is provided at the bottom of the hood-shaped mounting seat 5, and a plurality of cutting blades 7 are fixedly provided in the inner cavity of the semi-cylinder 6. A wedge-shaped soil-breaking head 11 is provided at the bottom of the semi-cylinder 6, a connecting seat 12 is provided at the top of the wedge-shaped soil-breaking head 11, a lower gasket 9 is provided at the top of the connecting seat 12, and a grooved baffle 8 is provided on the end surface of the lower gasket 9. The top of the grooved baffle 8 is arranged at the bottom of the hood-shaped mounting seat 5, and the bottom of the main rod 3 is fixedly connected to the hood-shaped mounting seat 5 to establish a connection and control of the semi-cylinder 6. The cutting blade 7 is provided in the semi-cylinder 6 to control its internal space. The cutting and dividing allows the semi-cylinder 6 to place the collected sediments in layers, which is convenient for researchers to study sediments at different depths and improve the detection and research value of sediments. The bottom of the semi-cylinder 6 breaks through the sediment layer of the intertidal zone through the wedge-shaped breaking head 11, driving the semi-cylinder 6 to quickly enter the sediment layer. The top of the wedge-shaped breaking head 11 uses the connecting seat 12 to establish the installation of the lower gasket 9, so that when the grooved baffle 8 is subjected to the steering force of the main rod 3, it drives the lower gasket 9 to rotate with the main rod 3. The main body 3 can be used to act on the semi-cylinder 6 to directly insert it into the intertidal zone. During the rotation of the grooved baffle 8, the sediment is pushed into the semi-cylinder 6, and samples of the sediment at its depth are collected.

[0027] See Figure 4 and Figure 5The top of the grooved baffle 8 is provided with an upper gasket 14, and the center of the upper gasket 14 is provided with a connecting post 15. The center of the bottom of the inner cavity of the cover-shaped mounting seat 5 is provided with a rotating setting seat 16. The connecting post 15 is embedded in the rotating setting seat 16, and the outer end of the rotating setting seat 16 is provided with a limiting anti-loosening pin 17. The inner cavity of the rotating setting seat 16 is provided with a rotating post 18. The top of the rotating post 18 is fixedly connected to the main rod 3, and the bottom of the rotating post 18 is fixedly connected to the connecting post 15. The upper gasket 14 fixes the connection between the connecting post 15 and the grooved baffle 8. The rotating setting seat 16 can be rotated in the inner cavity of the cover-shaped mounting seat 5, and cooperates with the limiting anti-loosening pin 17 to ensure the restrictive connection with the cover-shaped mounting seat 5 to prevent the rotating setting seat 16 from escaping from the bottom of the cover-shaped mounting seat 5. In the process of the main rod 3 driving the rotating post 18 to rotate through the connecting post 15, the grooved baffle 8 rotates 180 degrees, during which the semi-cylinder 6 remains stationary, and the grooved baffle 8 pushes the sediment into the semi-cylinder 6 to realize the collection of sediment.

[0028] See Figure 2 A bolt setting groove 13 is provided in the center of the connecting seat 12, and a lower connecting bolt 10 is provided in the center of the lower gasket 9. The bottom of the lower connecting bolt 10 is screwed into the bolt setting groove 13, and the lower gasket 9 is placed on the connecting seat 12. The lower connecting bolt 10 is screwed into the bolt setting groove 13 to establish a limited installation of the connecting seat 12 on the lower gasket 9, that is, under the rotation action of the main rod 3, the grooved baffle 8 is adjusted to realize rotation, and the lower gasket 9 and the lower connecting bolt 10 both rotate with the grooved baffle 8 at the same amplitude.

[0029] See Figure 1 The top of the main rod 3 is connected to the cross bar 1, and a group of rubber grips 2 are respectively provided at both ends of the cross bar 1. The top of the main rod 3 can be connected to the cross bar 1 by welding, that is, the downward pressure of the sampling personnel will not change the connection position and angle of the cross bar 1 and the main rod 3. The rubber grip 2 is provided on the cross bar 1 to increase the stability of the sampling personnel's contact with the cross bar 1 and avoid slipping. The cross bar 1 and the main rod 3 can be supported by metal materials. The rubber grip 2 can prevent the safety hazards caused by metal corrosion and improve the safety of the cross bar 1.

[0030] See Figure 2 A scale line 4 is provided at the center of the semi-cylinder 6 corresponding to the main rod 3. When the sampling personnel presses down the sampling device, the resistance on this side of the semi-cylinder 6 is greater, that is, the sampling personnel will stand on this side to press down and collect. The scale line 4 is set on the side of the semi-cylinder 6 corresponding to the main rod 3, which is convenient for the sampling personnel to check the pressing depth in real time and adjust the depth of the sample to be collected.

[0031] See Figure 1 and Figure 4One end of the grooved baffle 8 is set as a vertical frame, and the other end of the grooved baffle 8 is provided with an arc frame. The vertical frames of the grooved baffle 8 are respectively provided with through grooves at the positions corresponding to the cutting blade 7. The provision of the through grooves can make the grooved baffle 8 not affected by the setting of the cutting blade 7 and realize free rotation. The arc frame of the grooved baffle 8 is always set on the outside of the semi-cylinder 6. During the rotation of the grooved baffle 8, it can only rotate 180 degrees in the positive and negative directions around the center of the semi-cylinder 6. The vertical frame of the grooved baffle 8 is set on the inside of the semi-cylinder 6. Under the action of the rotating part, one side of the vertical frame rotates in the semi-cylinder 6. When it is necessary to collect samples, the main rod 3 is rotated to control the grooved baffle 8 to rotate accordingly, and the sediment sample is pushed into the semi-cylinder 6. When it is necessary to take out the sample, the main rod 3 is rotated in the opposite direction, and the plate on one side of the vertical frame can squeeze out the sample in the inner cavity of the semi-cylinder 6.

[0032] See Figure 1 The top of the cover-shaped mounting seat 5 is set as a truncated cone cover shell, and a number of protruding ridges are provided on the top surface of the cover-shaped mounting seat 5. The cover-shaped mounting seat 5 with a truncated cone structure can enhance its own structural performance, and the protruding ridges can increase the anti-slip performance of its surface, which makes it convenient for sampling personnel to apply vertical stepping pressure to it during sample collection, thereby speeding up the process of burying the sampling device into the soil.

[0033] See Figure 5 An anti-drop ring 19 is provided at the connection between the top of the hood-shaped mounting seat 5 and the main rod 3. The anti-drop ring 19 increases the firmness of the connection between the hood-shaped mounting seat 5 and the main rod 3 and reduces the wear on the hood-shaped mounting seat 5 caused by the rotation of the main rod 3.

[0034] The grooved baffle 8 is provided with a first notch corresponding to the connecting column 15, and the grooved baffle 8 is provided with a second notch corresponding to the lower connecting bolt 10. The first notch is provided to provide a setting space for the lower connecting bolt 10, and the second notch is provided to provide a setting space for the connecting column.

[0035] The wedge-shaped breaking head 11 is set as a vertical cutting structure with a conical diameter. The top of the wedge-shaped breaking head 11 is set in contact with the bottom edge of the semi-cylinder 6. The vertical cutting direction of the wedge-shaped breaking head 11 is consistent with the setting of the semi-cylinder 6, which makes it convenient for the wedge-shaped breaking head 11 to drive the semi-cylinder 6 to quickly enter the sediment layer of the intertidal zone, thereby realizing rapid sampling of the sediment.

[0036] The embodiment of the present invention provides an intertidal sediment sampling device. First, the grooved baffle 8 is moved to one side of the semi-cylinder 6 and the vertical frame is in contact with its cylinder wall to reduce the downward pressure resistance of the sampling device. The sampling device is pressed into the sediment and the insertion depth is adjusted according to needs. During this period, the position of the semi-cylinder 6 is limited by the sediment. The rubber grip 2 is held to drive the main rod 3 to rotate 180 degrees. The grooved baffle 8 will push the sample to the semi-cylinder 6 to collect the required sample. After the collection work is completed, the sampling device is taken out from the intertidal zone. The main rod 3 is rotated unidirectionally to control the grooved baffle 8 to take the sediment sample out of the semi-cylinder 6.

[0037] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present utility model.
