Abstract

Technical Field
[0001] The utility model relates to the field of underwater mud sampling, in particular to an underwater mud sampler. Background Art
[0002] The sediment (mud) of the water body can be regarded as a reservoir of chemical substances that enter the water body. The chemical composition of the mud can not only reflect the weathering and erosion of the rocks and soils in the land where the water source flows, but also has a good indication of environmental pollution and changes in the natural environment around the water body. There is a certain exchange of substances between the mud and the water body, and the chemical composition of the mud has a certain impact on the water quality of the water body and the organisms in the water. Through the mud, we can trace the source of pollution, reveal the laws of environmental changes, and the impact of human activities on water quality.
[0003] When existing mud samplers are used for mud sampling, a single barrel structure is mostly used for mud sampling operations, which results in mud leakage after the underwater mud sampling is completed, which wastes sampling time and affects the sampling efficiency. When underwater mud sampling is performed in deep water areas, divers are usually used for underwater sampling, which has low sampling efficiency and high risks. In order to solve the above problems, we propose an underwater mud sampler. Summary of the invention
[0004] The main purpose of the utility model is to provide a bottom mud sampler, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Preferably, the inner wall of the sealing box is fixedly connected to a vertical plate, the rear end of the vertical plate is fixedly connected to a motor base, the rear end of the motor base is fixedly installed with a motor, the output end of the motor is fixedly connected to a gear, the outer edge of the gear is meshed with a gear chain, the front end of the gear chain is fixedly connected to a cross bar, and the lower end of the cross bar is fixedly connected to the upper end of the lifting rod.
[0008] Preferably, a plurality of fixed blocks are fixedly connected to both sides of the front end gear chain of the vertical plate, the front ends of the plurality of fixed blocks are respectively fixedly connected to rails, and rail grooves are respectively provided on both sides of the gear chain, and the two groups of rails are slidably connected to the gear chain through the rail grooves.
[0009] Preferably, a plurality of feed ports are provided on the outer side of the insertion tube.
[0010] Preferably, a telescopic tube is fixedly connected to the upper end of the sealing box.
[0011] Preferably, a limit clamp ring is provided on the inner wall of the upper end of the insertion tube.
[0012] Compared with the prior art, the utility model has the following beneficial effects: with this underwater mud sampler, the user can insert the insertion tube into the underwater mud to be sampled through the extension function of the telescopic tube, so as to sample the mud on the bottom of deep water, avoid the risks brought by underwater sampling by divers, and improve the efficiency of sampling. The starting motor is used to drive the gear to rotate, and the rotation of the gear drives the gear chain and the cross bar to move upward, so that the lifting rod drives the sealing plate to move upward, resulting in negative pressure in the sampling tube, and the mud is sucked into the inner cavity of the sampling tube through the feed port under the action of pressure, and the piston is driven to rise when the sealing plate moves upward. The rise of the piston performs a sealing operation at the limit position of the limit clamp ring at the upper end of the insertion tube.

DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-4 As shown, a bottom mud sampler includes a sealed box 1, a sampling tube 4 is fixedly connected to the lower end of the sealed box 1, an insertion tube 3 is fixedly installed on the lower end of the sampling tube 4, the inner wall of the sampling tube 4 is slidably connected with 6, the upper end of 6 is fixedly connected with a lifting rod 5, the lower end of 6 is fixedly connected with a pull rod 7, the lower end of the pull rod 7 is fixedly connected with a piston 8, and the piston 8 is slidably connected to the inner wall of the insertion tube 3.
[0020] In this embodiment, the inner wall of the sealing box 1 is fixedly connected with a vertical plate 17, the rear end of the vertical plate 17 is fixedly connected with a motor base 14, the rear end of the motor base 14 is fixedly installed with a motor 15, the output end of the motor 15 is fixedly connected with a gear 13, the outer edge of the gear 13 is meshed with a gear chain 9, the front end of the gear chain 9 is fixedly connected with a cross bar 10, and the lower end of the cross bar 10 is fixedly connected to the upper end of the lifting rod 5.
[0021] Specifically, the motor 15 rotates to drive 13 to rotate, so that the gear chain 9 and the cross bar 10 rise, which facilitates the rise of the lifting rod 5.
[0022] In this embodiment, a plurality of fixed blocks 12 are fixedly connected to both sides of the front end gear chain 9 of the vertical plate 17, and the front ends of the plurality of fixed blocks 12 are respectively fixedly connected to rails 11. Rail grooves are respectively provided on both sides of the gear chain 9, and the two sets of rails 11 are slidably connected to the gear chain 9 through the rail grooves.
[0023] Specifically, track grooves are provided on both sides of the gear chain 9 to facilitate the gear chain 9 to move up and down on the track 11 through the track grooves.
[0024] In this embodiment, a plurality of feed ports 16 are provided on the outer side of the insertion tube 3 .
[0025] Specifically, by providing a plurality of feed ports 16 , it is possible to prevent individual feed ports 16 from being blocked by large particles in the mud, thereby affecting sampling.
[0026] In this embodiment, the upper end of the sealing box 1 is fixedly connected with a telescopic tube 2 .
[0027] Specifically, by extending the telescopic tube 2, it is convenient to sample the mud at the bottom of deeper waters.
[0028] In this embodiment, a limit clamp ring is provided on the inner wall of the upper end of the insertion tube 3 .
[0029] Specifically, by limiting the position of the piston 8 with the limiting clamp ring, the piston 8 can be prevented from entering the inner cavity of the sampling tube 4 and failing to seal the sampling tube 4 .
[0030] It should be noted that the utility model is an underwater mud sampler. The user will insert the insertion tube 3 into the underwater mud to be sampled through the extension function of the telescopic tube 2, start the motor 15, and the output end of the motor 15 drives the gear 13 to rotate. The rotation of the gear 13 drives the gear chain 9 to move upward, and the gear chain 9 moves upward to drive the cross bar 10 to move upward. Because the lifting rod 5 is fixedly connected to the cross bar 10, the lifting rod 5 drives 6 to move upward. The upward movement of 6 will cause negative pressure in the sampling tube 4, so that the mud is sucked into the inner cavity of the sampling tube 4 through the feed port 16 under the action of pressure, and when 6 moves upward, it will drive the piston 8 fixedly connected to the bottom end of the pull rod 7 to rise. The rising of the piston 8 performs a closing operation at the limit position of the limit clamp ring at the upper end of the insertion tube 3. First, it is convenient to prevent the mud sample entering the sampling tube 4 from flowing out when the sampling tube 4 is lifted, and second, it is convenient to play a quantitative role in the mud sample taken from the sampling tube 4.
