Description

A sediment sampler Technical Field

[0001] This utility model belongs to the field of geological exploration technology, specifically relating to a sediment sampler. Background Technology

[0002] In the field of geological exploration, accurate sampling of bottom sediments in water bodies is of great significance for studying the aquatic environment and geological evolution. However, existing sediment samplers require the sampler to be lowered to the bottom of the water body during the sampling process. This inevitably leads to the mixing of water and sediment when the sampler is opened to collect sediment, causing the collected sediment samples to be affected by the water and impacting the accuracy of subsequent analysis. When the sampler is removed from the water body, the excess water and mud increase the operational burden and reduce sampling efficiency. Summary of the Invention

[0003] This invention provides a sediment sampler that solves the problems of existing samplers that directly mix sediment with water, making it difficult to analyze the sediment separately and increasing the workload.

[0004] This utility model provides the following technical solution: It includes a support tube, with an arc-shaped support plate fixedly connected to the bottom of the support tube. A sampling box is provided below the support tube, and an installation tube corresponding to the support tube is fixedly connected to the top of the sampling box. Several drainage holes are opened at the bottom of the support tube. A lower fixing block is fixedly connected to the outside of the sampling box, and an upper fixing block is fixedly connected to the outer wall of the support tube. The upper fixing block and the lower fixing block are connected by a support rod. An installation plate is rotatably connected to one side of the lower fixing block. An adjustment frame is hinged to one end of the installation plate, and sealing arc plates matching the bottom of the sampling box and the top of the installation tube are fixedly connected to both ends of the installation plate.

[0005] The outer wall of the support pipe is provided with a drainage hole, and the arc-shaped support plate is in contact with the outer wall of the sealing arc plate.

[0006] A fixing rod is fixedly connected to one side of the lower fixing block. The fixing rod passes through the middle of the mounting plate, and one end of the fixing rod is fixedly connected to one side of the sampling box.

[0007] The sampling box is fixedly connected to an upper limit plate and a lower limit plate on one side, and the upper limit plate and the lower limit plate correspond to the mounting plate.

[0008] The outer wall of the support tube is fixedly connected to a limiting frame, which is offset from the adjusting frame.

[0009] The support rod is offset from the mounting plate, and a hinge column is installed at one end of the mounting plate. The bottom of the adjustment frame is hinged to the mounting plate through the hinge column.

[0010] The beneficial effects of this utility model are: by rotating the mounting plate on both sides of the sampling box, after collecting bottom mud, the sampling box and the mounting tube and the support tube can be sealed and separated from the support tube by adjusting the position of the mounting plate, the adjusting frame and the sealing arc plate. This allows the device to separate excess cement after collecting bottom mud, avoiding its mixing and affecting the separate collection of bottom mud. At the same time, it is easy to remove the bottom mud separately, reducing the burden.

[0011] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] Please refer to Figures 1-4. This utility model provides the following technical solution: It includes a support tube 1, an arc-shaped support plate 11 fixedly connected to the bottom of the support tube 1, a sampling box 2 provided below the support tube 1, an installation tube 12 corresponding to the support tube 1 fixedly connected to the top of the sampling box 2, a number of drainage holes 121 opened at the bottom of the support tube 1, a lower fixing block 22 fixedly connected to the outside of the sampling box 2, an upper fixing block 21 fixedly connected to the outer wall of the support tube 1, the upper fixing block 21 and the lower fixing block 22 are connected by a support rod 23, an installation plate 3 is rotatably connected to one side of the lower fixing block 22, an adjustment frame 32 is hinged to one end of the installation plate 3, and sealing arc plates 33 matching the bottom of the sampling box 2 and the top of the installation tube 12 are fixedly connected to both ends of the installation plate 3.

[0018] In this implementation scheme: During use, the support tube 1 has sufficient length and is hollow, allowing it to be easily inserted into the water and controlled. The bottom of the support tube 1 is lowered to the bottom of the water body. Pressing down on the support tube 1 causes the sampling box 2 located below it to move downwards, allowing it to penetrate the mud at the bottom of the water body. At this point, the lower fixing block 22 fixed to one side of the sampling box 2 corresponds vertically to the upper fixing block 21 fixed to the outer wall of the support tube 1. The upper fixing block 21 and the lower fixing block 22 are connected and fixed by a support rod 23, ensuring the support tube 1 and the sampling box are securely connected. The position between the two can be fixed, and the installation pipe 12 connected to the top of the sampling box 2 can correspond to the bottom of the support pipe 1. The distance between the bottom of the support pipe 1 and the top of the installation pipe 12 matches the sealing arc plate 33. When the sampling box 2 moves down, the installation plate 3 rotatably connected to one side of the lower fixing block 22 can be placed horizontally on both sides of the sampling box 2. At this time, the sampling box 2 can be pushed and displaced through the hollow bottom of the sampling box 2, so that the sampling box 2 can penetrate into the mud at the bottom of the water body, so that the mud can be placed inside the sampling box 2, thereby allowing the bottom mud to be collected into the sampling box 2. After being inserted into the sampling box 2, the horizontally placed mounting plate 3 is positioned on both sides of the sampling box 2. The sealing arc plates 33, which are fixedly connected to both ends of the mounting plate 3, are located on the outer side of the sampling box 2, ensuring that they do not affect the entry of bottom sediment into the inner cavity of the sampling box 2. After the sampling box 2 is inserted, the adjusting frame 32, which is hinged to the outer side of one end of the mounting plate 3, is positioned on the outer side of the support pipe 1, with the top of the adjusting frame 32 at the top of the support pipe 1 and above the water body. At this time, the adjusting frame 32 can be pushed to push one end of the mounting plate 3, causing the mounting plate 3 to move the sealing arc plates 33. Displacement occurs when the two sealing arc plates 33 are pushed by the mounting plate 3, causing them to be positioned at the top of the mounting pipe 12 and the bottom of the sampling box 2, respectively, thus sealing the sampling box 2. This allows the bottom sediment collected from the bottom of the water body to be separated within the sampling box 2 and the mounting pipe 12. When the device is lifted, excess water and soil in the support pipe 1 can be discharged directly from the drain hole 121, making it easier for the device to penetrate into the soil and collect the bottom sediment separately, avoiding mixing of water and bottom sediment. At the same time, excess cement can be discharged, reducing the burden of removing the device from the water body.

[0019] The outer wall of the support pipe 1 is provided with a drainage hole 121, and the arc-shaped support plate 11 is in contact with the outer wall of the sealing arc plate 33. The drainage hole 121 on the outer wall of the support pipe 1 can separate excess cement from the device. The arc-shaped support plate 11 is in contact with the outer wall of the sealing arc plate 33, so that the arc-shaped support plate 11 can play a supporting and guiding role for the rotational displacement of the sealing arc plate 33, ensuring that the sealing arc plate 33 is stably positioned at the top and bottom of the installation pipe 12 and the sampling box 2.

[0020] A fixing rod 221 is fixedly connected to one side of the lower fixing block 22. The fixing rod 221 passes through the center of the mounting plate 3, and one end of the fixing rod 221 is fixedly connected to one side of the sampling box 2. The fixing rod 221 fixedly connected to one side of the lower fixing block 22 can support and fix the lower fixing block 22. After the fixing rod 221 passes through the center of the mounting plate 3, it can make the mounting plate 3 rotate stably on one side of the lower fixing block 22 without affecting the fixation of the position of the lower fixing block 22. Furthermore, the connection between the lower fixing block 22 and the support rod 23 will not affect the rotation of the mounting plate 3.

[0021] An upper limit plate 34 and a lower limit plate 35 are fixedly connected to one side of the sampling box 2. The upper limit plate 34 and the lower limit plate 35 correspond to the mounting plate 3. The upper limit plate 34 and the lower limit plate 35 fixedly connected to one side of the sampling box 2 can limit the position of the mounting plate 3. When the mounting plate 3 is pushed to rotate by the control adjustment frame 32, the sealing arc plate 33 can be displaced. After that, the mounting plate 3 is limited by the upper limit plate 34 and the lower limit plate 35, so that the mounting plate 3 can be placed horizontally or vertically on both sides of the sampling box 2, thereby limiting and positioning the position of the sealing arc plate 33.

[0022] A limiting frame 321 is fixedly connected to the outer wall of the support tube 1. The limiting frame 321 is offset from the adjusting frame 32. The limiting frame 321 fixedly connected to the outer wall of the support tube 1 is used to limit the top of the adjusting frame 32 so that the top of the adjusting frame 32 will not separate from the top of the support tube 1, and the pushing displacement of the adjusting frame 32 will not be affected.

[0023] The support rod 23 is offset from the mounting plate 3. A hinge column 31 is installed at one end of the mounting plate 3. The bottom of the adjusting frame 32 is hinged to the mounting plate 3 through the hinge column 31. The offset between the support rod 23 and the mounting plate 3 allows the mounting plate 3 to be pushed by the adjusting frame 32, enabling the mounting plate 3 to make a stable pushing displacement. The hinge column 31 is used to hinge the bottom of the adjusting frame 32 to one end of the mounting plate 3, so that the mounting plate 3 can rotate to adjust the position of the sealing arc plate 33.

[0024] The working principle and usage process of this utility model are as follows: The support pipe 1 is lowered into the water body, ensuring its bottom reaches the bottom. Pressing down the support pipe 1 causes the sampling box 2 below to move downwards. Because the bottom of the sampling box 2 is hollow, the support pipe 1 is easily lowered, and the sampling box 2 is easily inserted into the bottom mud, allowing the bottom mud to enter the sampling box 2. After the bottom mud enters the sampling box 2, the mounting plates 3 placed horizontally on both sides of the sampling box 2, with their two ends fixedly connected to sealing arc plates 33, are located on the outside of the sampling box 2, not obstructing the entry of the bottom mud. At this time, the adjusting frame 32 hinged to the outside of one end of the mounting plate 3 is located outside the support pipe 1, and the adjusting frame... The top of the 32 is located above the water body. Pushing the adjustment frame 32 causes one end of the mounting plate 3 to move, which in turn causes the sealing arc plate 33 to move. Under the pushing action of the mounting plate 3, the two sealing arc plates 33 move to the top position of the mounting pipe 12 and the bottom position of the sampling box 2, respectively, thereby sealing the sampling box 2 and separating the collected bottom mud into the sampling box 2 and the mounting pipe 12. After sealing is completed, the sampler is pulled up, and excess water and mud in the support pipe 1 are discharged from the drainage hole 121 on the outer wall of the support pipe 1. This not only collects the bottom mud separately to avoid mixing water and mud, but also reduces the burden of removal.
