Description

Technical Field

[0001] This utility model belongs to the field of sampling equipment technology, specifically relating to a wetland water sampling device. Background Technology

[0002] Wetlands are naturally formed areas that are perennially or seasonally flooded. On beaches, the water depth does not exceed 6 meters at low tide. On land, they are land that is permanently or intermittently submerged by shallow water, with groundwater depth less than 3 meters and bottom sediment moisture content exceeding 30%. Therefore, they are water bodies with large seasonal or interannual water depth variations, exceeding 30%, such as marshes, wetlands, peatlands, mudflats, paddy fields, or other waterlogged areas. Sampling equipment is required when sampling the water bodies within wetlands.

[0003] For example, patent application number CN202321372942.3 discloses a wetland water sampling device, including: a sleeve, a screw threadedly connected to the inside of the sleeve, a collection tube rotatably mounted at the bottom end of the screw, a threaded sleeve integrally provided at the bottom end of the collection tube, a threaded tube rotatably mounted inside the threaded sleeve, and a circumferential groove equally spaced at the top of the threaded tube, with a filter screen engaged by the groove inside the threaded tube. This wetland water sampling device, provided by this utility model, rotates the screw by turning a handle, causing the collection tube to move downwards, contacting the wetland. As the collection tube continues to move downwards, mud and impurities are blocked by the filter screen, water enters the inside of the collection tube, the sampling valve is opened, water enters the sampling tube, and finally enters the sampling bottle, completing the sampling operation. However, this sampling device can only collect one sample at a time, and it relies on manual sampling, limiting sampling to areas near shallow water or low-lying areas. This makes it difficult to guarantee the accuracy and comprehensiveness of the samples, and also makes it difficult to guarantee the reliability and scientific validity of subsequent testing.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a wetland water collection device that can collect water samples from different areas of a wetland, ensuring the accuracy and comprehensiveness of the samples.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A wetland water sampling device includes a sampling mechanism and a remotely controlled floating vessel. The sampling mechanism is detachably connected to the bottom of the floating vessel. The sampling mechanism includes a sampling cylinder, a rotating sleeve rotatably fitted on the outer wall of the sampling cylinder, and a driving assembly for driving the rotating sleeve to rotate. A connecting column is coaxially arranged inside the sampling cylinder, and multiple independent receiving cavities are arranged in a circular array inside the sampling cylinder, with partition plates between adjacent receiving cavities. Multiple first water inlets are formed on the side wall of the sampling cylinder, each communicating with one of the receiving cavities. A second water inlet is formed on the rotating sleeve, corresponding to and communicating with the first water inlets.

[0008] Furthermore, the height of the multiple first water inlets decreases progressively in a clockwise or counterclockwise direction; there are multiple second water inlets arranged vertically, with each second water inlet corresponding to each of the first water inlets. By staggering the heights of the first water inlets and ensuring that each first water inlet corresponds to a second water inlet, cross-contamination of samples within each receiving cavity can be avoided.

[0009] Furthermore, a filter plate with several filter holes is provided inside the second water inlet; multiple sealing rings are formed on the inner wall of the rotating sleeve, each fitting onto the second water inlet. The filter plate can effectively filter out some larger impurities in the water.

[0010] Furthermore, the sampling tube has a bottom cover with multiple drain pipes corresponding to the receiving cavity, and each drain pipe has a cap at its bottom. The bottom cover also has a connecting screw that connects to the connecting post, and the bottom of the connecting post has a threaded hole that mates with the connecting screw. A knob is also located at the bottom of the bottom cover. A sealing gasket is provided between the sampling tube and the bottom cover. By providing the bottom cover, the sampling tube can be opened for cleaning after each water sample collection.

[0011] Furthermore, a rotating ring is formed on the inner wall of the rotating sleeve to rotatably engage with the sampling tube, and a rotating groove is formed on the top of the sampling tube to engage with the rotating ring; the driving assembly includes a driving gear, a rotating shaft mounting the driving gear, and a motor driving the rotating shaft to rotate; an internal gear ring meshing with the driving gear is provided on the inner wall of the rotating sleeve; the rotating shaft is rotatably connected to the top of the sampling tube, the driving gear is mounted on the rotating shaft, and the motor is fixedly mounted on the floating vessel; a mounting box for mounting the motor is provided at the bottom of the floating vessel. The gear drive allows for more stable adjustment of the rotating sleeve's rotation angle, aligning the second water inlet hole with the first water inlet hole.

[0012] Furthermore, the bottom of the floating vessel is provided with a mounting base for installing the sampling mechanism. The top of the sampling cylinder forms a mounting platform with multiple insertion pins and connecting blocks on the platform. The top of the mounting base has insertion holes that mate with the insertion pins and connecting grooves that mate with the connecting blocks. The mounting base also has a locking mechanism. One side of the connecting block has a locking groove. The locking mechanism includes a locking element and a spring. The locking element includes a lock head that can be inserted into the locking groove, a control pull plate, and a pull rod connecting the lock head and the control pull plate. The mounting base has a movable cavity for the locking element to move. The spring is sleeved on the pull rod. Using the locking mechanism, the sampling mechanism can be quickly assembled and disassembled.

[0013] Furthermore, a camera is also installed on the top of the floating vessel. The camera allows operators to easily observe the movement of the floating vessel.

[0014] With the above structure, the wetland water sampling device of this utility model, compared with the prior art, sets the sampling mechanism at the bottom of a remotely controlled floating vessel. The floating vessel carries the sampling mechanism to different areas to sample the water. In addition, multiple receiving cavities are provided in the sampling tube, and a rotating sleeve is rotatably fitted on the outer wall of the sampling tube. The rotating sleeve is driven to rotate by a drive component. Each time it reaches a region, the rotating sleeve is adjusted to connect the second water inlet hole with the first water inlet hole of the corresponding receiving cavity, so that the water sample can enter the corresponding receiving cavity. In this way, water in different areas of the wetland can be collected separately, ensuring the accuracy and comprehensiveness of the samples, thereby ensuring the accuracy and scientific nature of subsequent testing.

Detailed Implementation

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0028] like Figures 1-10As shown, this utility model relates to a wetland water sampling device, which includes a sampling mechanism and a remotely controlled floating boat 1. A camera 13 is also provided on the top of the floating boat 1, which allows the operator to observe the movement of the floating boat 1. In addition, the sampling mechanism is detachably connected to the bottom of the floating boat 1. After the sampling is completed, the sampling mechanism can be detached from the bottom of the floating boat 1 to remove the sample. Specifically, the sampling mechanism includes a sampling cylinder 2, a rotating sleeve 3 disposed on the outer wall of the sampling cylinder 2, and a driving component 4 for driving the rotating sleeve 3 to rotate. A connecting column 21 is coaxially provided inside the sampling cylinder 2, and multiple independent receiving cavities 22 are arranged in a circular array inside the sampling cylinder 2. A partition plate 23 is provided between adjacent receiving cavities 22. Multiple first water inlet holes 24 are formed on the side wall of the sampling cylinder 2, which are respectively connected to the receiving cavities 22. A second water inlet hole 31 is formed on the rotating sleeve 3, which is connected to the first water inlet hole 24. During sampling, the sampling mechanism is carried to the area to be sampled by the floating vessel 1. Upon arrival at each area, the rotating sleeve 3 is rotated once by the drive component 4, connecting the second water inlet 31 with the first water inlet 24 of the corresponding receiving cavity 22, thereby allowing the water sample to enter the receiving cavity 22. In this way, water samples can be collected from different areas of the wetland, ensuring the accuracy and comprehensiveness of the samples, thus guaranteeing the accuracy and scientific validity of subsequent testing.

[0029] Specifically, to avoid cross-contamination of water samples in each containment cavity 22, the heights of multiple first water inlets 24 decrease progressively in a clockwise or counterclockwise direction and are staggered. Similarly, there are multiple second water inlets 31, arranged vertically, each corresponding to one of the first water inlets 24. In this embodiment, there are six containment cavities 22, each with a corresponding first water inlet 24. The included angle between adjacent water inlets is the same. The six first water inlets 24 decrease progressively in a clockwise direction. There are also six second water inlets 31, each with the same height as the six first water inlets 24. When the sampling area is not reached, the second water inlets 31 and the first water inlets 24 are staggered, meaning the second water inlets 31 are located between the first and sixth containment cavities 22. The included angle between them is 30°. When the first area is reached, the rotating sleeve 3 is controlled to rotate 30° clockwise so that the second water inlet 31 corresponds to the first water inlet 24 on the first receiving cavity 22, so that water can enter the receiving cavity 22. Then, the rotating sleeve 3 is controlled to rotate 30° clockwise again so that the first water inlet 24 and the second water inlet 31 are misaligned. Then, the floating boat 1 is controlled to reach the next area, and the transmission sleeve is controlled to rotate 30° clockwise so that the first water inlet 24 of the next receiving cavity 22 corresponds to the next second water inlet 31 again, so that water can enter the receiving cavity 22.

[0030] In this embodiment, to filter out some larger impurities in the water, a filter plate 32 is provided inside the second water inlet 31, and a plurality of filter holes are formed on the filter plate 32; a plurality of sealing rings 33 are formed on the inner wall of the rotating sleeve 3, which are respectively fitted onto the second water inlet 31. The sealing rings 33 prevent water from entering the gap between the rotating sleeve 3 and the sampling cylinder 2.

[0031] In this embodiment, to facilitate cleaning of the sampling tube 2 after sample collection, a bottom cover 25 is provided at the bottom of the sampling tube 2. Multiple drain pipes 251, each corresponding to the receiving cavity 22, are formed on the bottom cover 25. A cap 252 is also provided at the bottom of each drain pipe 251. The cap can be threadedly connected to the drain pipe 251. A rubber gasket can be placed inside the cap 252 to enhance sealing. The collected water sample can be removed through the drain pipe 251 for testing. The bottom cover 25 is also provided with a connector that connects to the connecting post 21. The connecting screw 253 is connected to the bottom of the connecting post 21, which forms a threaded hole 211 that mates with the connecting screw 253. The bottom of the bottom cover 25 is also provided with a knob 254. A sealing gasket 26 is also provided between the sampling cylinder 2 and the bottom cover 25. Similarly, the sealing gasket 26 can enhance the sealing between the bottom cover 25 and the sampling cylinder 2. The sealing gasket 26 is specifically composed of two concentric washers and multiple sealing strips connected between the two concentric washers. The sealing strips correspond to the partition plate 23, and the two concentric washers correspond to the bottom of the connecting post 21 and the bottom of the sampling cylinder 2, respectively.

[0032] In this embodiment, a rotating ring 34 is formed on the inner wall of the rotating sleeve 3 to rotate with the sampling tube 2, and a rotating groove 27 is formed on the top of the sampling tube 2 to rotate with the rotating ring 34. The rotating groove 27 and the rotating ring 34 are L-shaped. The drive assembly 4 includes a drive gear 41, a rotating shaft 42 for mounting the drive gear 41, and a motor 43 for driving the rotating shaft 42. An internal gear ring 35 that meshes with the drive gear 41 is provided on the inner wall of the rotating sleeve 3. The rotating shaft 42 is rotatably connected to the top of the sampling tube 2. The drive gear 41 is mounted on the rotating shaft 42. The drive gear 41 and the rotating shaft 42 are connected by a key. The motor 43 is fixedly mounted on the floating vessel 1. The output shaft of the motor 43 is connected to the rotating shaft 42 by a key, and the output shaft of the motor 43 can be removed from the rotating shaft 42. The bottom of the floating vessel 1 is provided with a mounting box 11 for mounting the motor 43. The output shaft of the motor 43 can pass through the mounting box 11, and the output shaft of the motor 43 and the mounting box 11 are in a rotating sealed fit. The rotation angle of the rotating sleeve 3 can be adjusted more stably by using gear drive, so that the second water inlet 31 is aligned with the first water inlet 24.

[0033] In this embodiment, the bottom of the floating vessel 1 is also provided with a mounting base 12 for installing the sampling mechanism. The top of the sampling tube 2 is formed with a mounting platform 28, and the mounting platform 28 has multiple plug-in pins 281 and connecting blocks 282. The top of the mounting base 12 is formed with plug-in holes 121 that cooperate with the plug-in pins 281 and connecting grooves 122 that cooperate with the connecting blocks 282. The mounting base 12 is also provided with a locking mechanism 5. A locking groove 2821 is formed on one side of the connecting block 282. The locking mechanism 5 includes a locking member 51 and a spring 52. The locking member 51 includes a lock head 511 that can be inserted into the locking groove 2821, a control pull plate 512, and a pull rod 513 connected between the lock head 511 and the control pull plate 512. A handle is provided on the control pull plate 512. The mounting base 12 is formed with a movable cavity 123 for the locking member 51 to move. The spring 52 is sleeved on the pull rod 513. The sampling mechanism can be quickly disassembled and assembled using the locking mechanism 5. In specific operation, the sampling mechanism can be removed from the floating vessel 1 by pulling the control plate 512 and pulling the lock head 511 out of the lock groove 2821. Similarly, during installation, the lock head 511 is inserted into the lock groove 2821 and the spring 52 prevents the lock head 511 from slipping out.

[0034] The method of using this utility model is as follows: During sampling, the sampling mechanism is carried to the area to be sampled by the floating vessel 1. Upon reaching each area, the rotating sleeve 3 is rotated once by the drive component 4, so that the second water inlet 31 is connected to the first water inlet 24 of the corresponding receiving cavity 22, thereby allowing the water sample to enter the receiving cavity 22. In this way, water samples can be collected from different areas of the wetland.

[0035] The above provides a detailed description of a wetland water sampling device provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
