DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0022] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] Reference Figures 1 to 8 , which is the first embodiment of the present invention, proposes a water sample collection device for water environment management, including a sampling bucket and a hanging rope arranged on the sampling bucket, and also includes a bracket 1 for being set on the ground, and the bracket 1 is height-adjustable; a first telescopic rod 2 is clamped and arranged on the bracket 1, the first telescopic rod 2 has a telescopic end, the hanging rope is passed through the telescopic end, and the first telescopic rod 2 is used to drive the sampling bucket to move after being extended.

[0025] In this embodiment, sampling river water in the prior art still requires a sampler to stand by the river to collect water. This collection method can be inconvenient for the sampler in complex terrain. The bracket 1 in this embodiment adopts a retractable structural design, for example, using a multi-section casing. The height of the bracket 1 can be adjusted by tightening or loosening specific fastening bolts to adapt to different sampling environments and water depth requirements. The first telescopic rod 2 can be extended and retracted to collect water from the riverside or in the middle of the river.

[0026] The first telescopic rod 2 is fixedly fastened to the bracket 1, allowing for easy adjustment of its angle and position. A smooth threading hole is provided on the first telescopic rod 2 for the passage of a sling. When the first telescopic rod 2 is extended or retracted, the sling drives the sampling bucket to move, enabling water sample collection.

[0027] Adjust bracket 1 to the appropriate height and secure it to the ground. Attach the first telescopic rod 2 to bracket 1, adjusting its angle and position. Thread the sling through the threading hole of the first telescopic rod 2 and connect it to the sampling bucket. Extend and retract the first telescopic rod 2 to move the sampling bucket above the sampling area. Release the sling and lower the bucket to the designated depth in the water to collect water samples. Once the water sample is collected, raise the bucket to the surface.

[0028] The bracket 1 is height-adjustable and can adapt to the terrain changes at different sampling locations, allowing the water sample collection device to be used in various complex water environments. The provision of the first telescopic rod 2 makes the movement of the sampling bucket more flexible, and the lowering depth of the sampling bucket can be precisely controlled, thereby improving the accuracy and representativeness of the sampling. The structural design of the entire device is simple and easy to operate. The lowering and lifting of the sampling bucket can be completed by telescoping the first telescopic rod 2 without the need for complex mechanical operations, which greatly improves the sampling efficiency. The stable base and adjustable height design of the bracket 1 ensure the stability of the device during the sampling process and reduce sampling errors caused by shaking or tilting. The clamping structure of the first telescopic rod 2 and the bracket 1 is firm and reliable, capable of bearing the weight of the sampling bucket and water samples, ensuring the safety of the sampling process. The water sample collection device is suitable for water sample collection work in various water environment management projects, including different types of water bodies such as rivers, lakes, ponds, and oceans, providing strong technical support for water environment management.

[0029] Furthermore, the bracket 1 includes a mounting base 11; a plurality of second telescopic rods 12, one end of which is set on the mounting base 11 and the other end is used to be set on the ground, and the plurality of second telescopic rods 12 are set on the mounting base 11 at intervals along the circumference.

[0030] In this embodiment, the mounting base 11 can be made of a circular or polygonal metal plate, which provides sufficient strength and stability. Each second telescopic rod 12 is connected to the mounting base 11 at one end and has a sharp plug or a base with a non-slip pad at the other end for insertion into the ground or for stable placement on the ground. The number of second telescopic rods 12 can be determined based on actual needs, typically three or four, evenly spaced around the circumference of the mounting base 11.

[0031] Multiple second telescopic rods 12 are spaced circumferentially on the mounting base 11, forming a stable support structure that effectively prevents the bracket 1 from tilting or shaking during sampling, thereby enhancing the stability of the entire water sampling device. The second telescopic rods 12 can be adjusted in length according to the ground conditions, ensuring that the mounting base 11 remains level, further improving sampling accuracy and reliability. This bracket 1 structure adapts to a variety of terrains, from flat ground to rugged, uneven riverbanks or coastal areas. The length of the second telescopic rods 12 can be adjusted to ensure stable placement of the device. For soft surfaces, the second telescopic rods 12, equipped with sharp plugs, can be inserted into the ground to increase the bracket 1's grip. For hard surfaces, the base with anti-slip pads provides excellent stability. The mounting base 11 and the second telescopic rods 12 utilize a detachable connection for easy assembly and disassembly. During transportation and storage, the components can be separated, reducing space and making it easier to carry. For field use, the bracket 1 can be quickly assembled, improving work efficiency.

[0032] Furthermore, the second telescopic rod 12 includes a first fixed rod 121, which is arranged on the mounting seat 11; a first sliding rod 122, which is slidably arranged on the first fixed rod 121; a second sliding rod 123, which is slidably arranged on the first sliding rod 122; and a support leg 124, which is arranged on the second sliding rod 123, and the support leg 124 is used to abut the ground.

[0033] In this embodiment, a scale can be provided on the outer surface of the first fixed rod 121 to facilitate accurate adjustment of the length of the second telescopic rod 12. A locking bolt is provided on the upper portion of the first fixed rod 121 to secure the position of the first sliding rod 122. The first sliding rod 122 can slide smoothly on the first fixed rod 121. A locking bolt is also provided on the upper portion of the first sliding rod 122. When the first sliding rod 122 is extended to the desired length, tightening the locking bolt secures it to the first fixed rod 121. One end of the second sliding rod 123 can slide on the first sliding rod 122, and the other end is connected to the support leg 124. Similarly, a locking bolt is provided on the upper portion of the second sliding rod 123 to secure the position of the second sliding rod 123. By adjusting the extended length of the first sliding rod 122 and the second sliding rod 123, the total length of the second telescopic rod 12 can be precisely controlled.

[0034] The support legs 124 can be round, square, or other shapes, and can have non-slip rubber pads on their bottoms to increase friction with the ground. The support legs 124 are secured to the ends of the second slide bar 123 by welding or bolting. When adjusting the length of the second telescopic rod 12, the support legs 124 move closer to or further from the ground as the second slide bar 123 moves, ultimately coming into contact with the ground, providing stable support for the entire stand 1.

[0035] The second telescopic rod 12 adopts a three-section design, namely the first fixed rod 121, the first slide rod 122 and the second slide rod 123, which can achieve more precise length adjustment. This enables the bracket 1 to adapt to sampling requirements of various heights and improves the applicability of the water sample collection device. By reading the scale on the first fixed rod 121, the length of the second telescopic rod 12 can be accurately known, thereby ensuring that the lengths of the legs of each bracket 1 are consistent, so that the mounting base 11 remains horizontal and the accuracy of sampling is improved. The provision of the support legs 124 further improves the contact stability between the bracket 1 and the ground, prevents the bracket 1 from sliding or tilting on the ground, and ensures the safety and reliability of the water sample collection process. When adjusting the length of the second telescopic rod 12, it is only necessary to loosen the corresponding locking bolt and slide the first slide rod 122 and the second slide rod 123. The operation is simple and convenient, without the need for other complicated tools, which greatly improves work efficiency.

[0036] Furthermore, the first fixed rod 121 is hingedly set on the mounting base 11, and also includes a third telescopic rod 3, which has several ends, one end of which is correspondingly swing-set on the first fixed rod 121, and the other end is a clamping end 31. The several clamping ends 31 are used to clamp each other, and the third telescopic rod 3 swings vertically.

[0037] In this embodiment, the first fixed rod 121 can rotate on the mounting base 11, and upon rotation, the plurality of legs 124 can move away from each other to adapt to different terrains. One end of each third telescopic rod 3 is connected to the first fixed rod 121 via a hinge, allowing the third telescopic rod 3 to swing vertically. The other end of the third telescopic rod 3 is a snap-on end 31, which can be designed in a hook or slot shape. Multiple snap-on ends 31 of the third telescopic rod 3 can be snapped together to form a stable structure, preventing the second telescopic rod 12 from shifting after the second telescopic rod 12 is adjusted.

[0038] When installing the bracket 1, first rotate the first fixing rod 121 to the appropriate angle so that each second telescopic rod 12 can adapt to the ground topography. Then, adjust the length of the second telescopic rod 12 as needed so that the support legs 124 abut the ground. Next, extend each third telescopic rod 3 to the appropriate position, interlocking the connecting ends 31 to further enhance the stability of the bracket 1. Finally, attach the first telescopic rod 2 to the mounting base 11 to begin water sampling.

[0039] The first fixed rod 121 is rotatably mounted on the mounting base 11, allowing for flexible adjustment of the angles of the second and third telescopic rods 12 and 3 according to different sampling locations and terrain, enabling the bracket 1 to better adapt to complex ground conditions. The swingable design and interlocking function of the third telescopic rod 3 allow the bracket 1 to form a more stable support structure on uneven ground, improving the applicability of the water sampling device in complex terrain.

[0040] Furthermore, the third telescopic rod 3 includes a second fixed rod 32, which is vertically swingingly set on the second sliding rod 123, and the upper end surface of the second fixed rod 32 has teeth; the third sliding rod 33, one end of which is slidingly set on the second fixed rod 32, and the other end is a clamping end 31; a clamping member 34, which is lifted and lowered on the third sliding rod 33, and the clamping member 34 also has teeth. After the clamping member 34 descends, the teeth of the second fixed rod 32 engage with the teeth of the clamping member 34.

[0041] In this embodiment, one end of the second fixed rod 32 is connected to the second slide rod 123 via a rotating shaft, allowing the second fixed rod 32 to swing freely in the vertical direction. Evenly distributed teeth are machined on the upper end surface of the second fixed rod 32. The third slide rod 33 is a hollow structure with an inner diameter slightly larger than the outer diameter of the second fixed rod 32, allowing the third slide rod 33 to slide on the second fixed rod 32. One end of the third slide rod 33 is inserted into the second fixed rod 32, and the other end serves as a clamping end 31 for interlocking with the clamping end 31 of the other third telescopic rod 3.

[0042] The clamping member 34 is a block-shaped structure with teeth. Its dimensions match those of the third slide bar 33 and allows it to be raised and lowered on the third slide bar 33. To fix the position of the third slide bar 33, the clamping member 34 is lowered, causing the teeth on the clamping member 34 to engage with the teeth on the upper end surface of the second fixed rod 32. At this point, the third slide bar 33 cannot slide on the second fixed rod 32, thereby fixing the length of the third telescopic rod 3.

[0043] The third telescopic rod 3 utilizes a combination of a second fixed rod 32, a third sliding rod 33, and a clip 34 to enhance the stability of the bracket. By adjusting the extension of the third sliding rod 33 from the second fixed rod 32 and using the teeth of the clip 34 to maintain the fixed length, the stability of the bracket 1 and the accuracy of water sample collection are improved. The clip 34 can be raised and lowered simply by using a handle. Adjusting the length of the third telescopic rod 3 eliminates the need for complex tools, significantly improving work efficiency. Furthermore, the toothed engagement ensures a secure and reliable connection, preventing loosening.

[0044] Furthermore, the mounting base 11 has a first clamping hole 111 and also includes a fixing base 4, the first telescopic rod 2 is clamped and set on the fixing base 4, and the first telescopic member 2 is clamped and set on the bracket 1 through the fixing base 4; the first clamping column 5 is set on the fixing base 4 and has a plurality of first mounting holes 51 arranged along the circumference; the first elastic member 6 has a plurality of first mounting holes 51 correspondingly arranged in the first mounting holes 51; the first stop block 7 has a plurality of first elastic members 6 correspondingly arranged in the first mounting hole 51, and after extending, the first stop block 7 is clamped with the fixing base 4 on both sides of the first clamping hole 111.

[0045] In this embodiment, the mounting base 11 is a circular or polygonal metal plate with a first engaging hole 111 defined at its center. The fixing base 4 is a metal block of a certain thickness, to which the first telescopic rod 2 can be securely attached. The first engaging post 5 is cylindrical, with a diameter smaller than that of the first engaging hole 111. One end of the first engaging post 5 is fixed to the fixing base 4, and the other end is inserted into the first engaging hole 111 of the mounting base 11. The first elastic member 6 can be a spring, with one spring installed in each first mounting hole 51. One end of the spring is fixed to the bottom of the first mounting hole 51, and the other end is connected to the first stop 7. The first stop 7 is a wedge-shaped structure, slightly smaller than the diameter of the first mounting hole 51. In its natural state, the first stop 7 partially extends out of the first mounting hole 51 under the action of the spring. When the first engaging post 5 is inserted into the first engaging hole 111 of the mounting base 11, the first stop 7 is squeezed by the mounting base 11, compressing the spring and sliding into the first mounting hole 51. When the first clamping post 5 is fully inserted into the first clamping hole 111, the first stopper 7 extends out of the first mounting hole 51 under the action of the spring, and cooperates with the fixing seat 4 to be clamped on both sides of the first clamping hole 111, thereby firmly fixing the first telescopic rod 2 on the mounting seat 11.

[0046] Through the cooperation of the first clamping column 5, the first elastic member 6 and the first stopper 7, the first telescopic rod 2 can be firmly clamped to the mounting base 11. During the water sample collection process, even if it is subjected to external impact or vibration, the first telescopic rod 2 will not easily loosen or fall off, ensuring the stability and safety of the water sample collection device. During installation, it is only necessary to insert the first clamping column 5 into the first clamping hole 111 of the mounting base 11. The first stopper 7 automatically extends and clamps on both sides of the first clamping hole 111 under the action of the spring, and the installation is complete. During disassembly, it is only necessary to forcefully lift the first telescopic rod 2 upward so that the first stopper 7 overcomes the elastic force of the spring and slides into the first mounting hole 51. The first telescopic rod 2 can then be removed from the mounting base 11. The operation is simple and convenient, saving installation and disassembly time.

[0047] Furthermore, the side wall of the fixing seat 4 has a first through hole 41, and also includes a second clamping column 8, which is arranged on the first telescopic rod 2 and has a plurality of second mounting holes 81 arranged along the circumference; the second elastic member 9 has a plurality of correspondingly arranged in the second mounting holes 81; the second stop block 10 has a plurality of correspondingly arranged on the second elastic member 9, the second stop block 10 is slidably set in the second mounting hole 81, and after extending, cooperates with the first telescopic rod 2 to be clamped on both sides of the first through hole 41; the sliding sleeve 110 is slidably set on the second clamping column 8, and after the sliding sleeve 110 slides, it is used to push the second stop block 10 to slide into the second mounting hole 81.

[0048] In this embodiment, the second clamping post 8 can be cylindrical or non-circular. The non-circular structure prevents the fixing base from accidentally rotating. One end of the second clamping post 8 is fixed to the first telescopic rod 2, and the other end is inserted into the first through-hole 41 of the fixing base 4. The second elastic member 9 can be a spring, with one spring installed in each second mounting hole 81. One end of the spring is fixed to the bottom of the second mounting hole 81, and the other end is connected to the second stopper 10. The second stopper 10 is a wedge-shaped structure, and the spring acts to partially extend the second stopper 10 out of the second mounting hole 81. The sliding sleeve 110 is a cylindrical structure with an inner diameter slightly larger than the outer diameter of the second clamping post 8, allowing it to slide on the second clamping post 8. An annular groove is provided on the inner wall of the sliding sleeve 110. When the sliding sleeve 110 slides to a certain position, the second stopper 10 slides into the annular groove. A handle or pull ring is provided on the outer wall of the sliding sleeve 110 to facilitate operation of the sliding sleeve 110. To remove the first telescopic rod 2 from the mounting base 4, push the sliding sleeve 110, causing it to slide toward the end of the second clamping post 8. As the sliding sleeve 110 slides, its inner wall gradually compresses the second stopper 10, forcing it to slide into the second mounting hole 81, overcoming the spring force. At this point, the second clamping post 8 can be removed from the first through hole 41 of the mounting base 4, completing the removal of the first telescopic rod 2.

[0049] The cooperation of the second clamping post 8, the second elastic member 9, and the second stopper 10 securely fastens the first telescopic rod 2 to the fixing base 4. During the water sampling process, the first telescopic rod 2 will not easily loosen or fall off, ensuring the stability and safety of the water sampling device. The stable and reliable connection and convenient disassembly allow for quick replacement of the first telescopic rod 2 or maintenance during use, improving work efficiency.

[0050] Furthermore, the second clamping column 8 has a threaded section, and the first telescopic rod 2 includes a first sleeve 21, which is clamped on the mounting seat 11, and the second clamping column 8 is rotatably set on the first sleeve 21; the second sleeve 22 is slidably set in the first sleeve 21, and the thread is set on the threaded section. After the second clamping column 8 rotates, it drives the second sleeve 22 to slide in or out of the first sleeve 21; the third sleeve 23 is rotatably set on the second sleeve 22, and is slidably set on the second clamping column 8. After the second clamping column 8 rotates, it drives the third sleeve 23 to rotate; the fourth sleeve 24 is slidably set on the second sleeve 22, and is threaded on the third sleeve 23.

[0051] In this embodiment, the first sleeve 21 is a hollow structure, one end of which is provided with a snap-fit ​​structure that cooperates with the fixing seat 4 on the mounting seat 11, and can be securely snapped onto the mounting seat 11. The second snap-fitting post 8 is a threaded rod, one end of which is threadedly mounted on the first sleeve 21, so that when the second snap-fitting post 8 rotates, it can drive the first sleeve 21 to slide. The second sleeve 22 is a hollow structure, with an outer diameter slightly smaller than the inner diameter of the first sleeve 21, and can slide within the first sleeve 21. The bottom of the second sleeve 22 is provided with an internal thread that cooperates with the second snap-fitting post 8. When the second snap-fitting post 8 rotates, the second sleeve 22 is driven to slide in or out of the first sleeve 21 through the threaded transmission. To ensure the stability of the second sleeve 22 during the sliding process, a guide groove can be provided on the inner wall of the first sleeve 21, and a corresponding guide block can be provided on the outer wall of the second sleeve 22. The guide block slides within the guide groove to prevent the second sleeve 22 from rotating. The third sleeve 23 is a hollow structure with an outer diameter slightly smaller than the inner diameter of the second sleeve 22, allowing it to rotate on the second sleeve 22. The third sleeve 23 has threads on its outer side, and a through hole is provided at the bottom of the third sleeve 23 that mates with the second clamping post 8, allowing the third sleeve 23 to be sleeved on the second clamping post 8 and rotate freely. The outer wall of the third sleeve 23 is provided with external threads for connecting with the fourth sleeve 24. The fourth sleeve 24 can slide on the second sleeve 22. The bottom of the fourth sleeve 24 is provided with internal threads that mate with the third sleeve 23. When the third sleeve 23 rotates, the fourth sleeve 24 is driven to slide in or out of the second sleeve 22 through threaded transmission.

[0052] Rotation of the second clamping post 8 drives the second sleeve 22 and the fourth sleeve 24 to slide within the first sleeve 21 and the second sleeve 22, respectively, thereby achieving multi-stage telescopic adjustment of the first telescopic rod 2. This design allows for flexible adjustment of the length of the first telescopic rod 2 according to different sampling requirements, improving the applicability of the water sampling device. The telescopic adjustment of the first telescopic rod 2 is achieved simply by rotating the second clamping post 8, making operation simple and convenient. This eliminates the need for complex tools and significantly improves work efficiency.

[0053] Furthermore, the bottom of the fixing seat 4 also has a second through hole 42 , and the second clamping column 8 passes through the second through hole 42 . After the second stopper 10 extends out of the second mounting hole 81 , the second clamping column 8 is used to be clamped in the second through hole 42 .

[0054] In this embodiment, the mounting base 4 is a block-shaped structure of a certain thickness. The top portion, which engages the first telescopic rod 2, is provided with a groove matching the outer diameter of the first telescopic rod 2 to ensure stability after installation. A second through-hole 42 is provided at the bottom center of the mounting base 4. The diameter of the second through-hole 42 is slightly larger than that of the second engaging post 8, allowing smooth passage of the second engaging post 8. A second elastic member 9 (e.g., a spring) and a second stopper 10 are mounted within the second mounting hole 81. In its natural state, the second stopper 10 partially extends out of the second mounting hole 81 under the action of the second elastic member 9.

[0055] Insert the second clamping post 8 at the bottom of the first telescopic rod 2 through the second through-hole 42 at the bottom of the fixing base 4. During the insertion process, the second stopper 10 is squeezed by the fixing base 4, compressing the second elastic member 9 and sliding into the second mounting hole 81. After the second clamping post 8 is completely passed through the second through-hole 42, the second stopper 10, under the action of the second elastic member 9, extends out of the second mounting hole 81. At this time, the first telescopic rod 2 is clamped in the second through-hole 42 of the fixing base 4, achieving a secure connection between the first telescopic rod 2 and the fixing base 4. With the first telescopic rod 2 facing downward, well water or sewer water can be collected. After the first telescopic rod 2 is extended and retracted, it drives the sampling bucket to move.

[0056] During installation, the connection is completed by simply inserting the second clamping post 8 at the bottom of the first telescopic rod 2 through the second through-hole 42 at the bottom of the fixing base 4, making operation simple and convenient. During disassembly, the second stopper 10 can be slid into the second mounting hole 81 by sliding the sleeve 110, making it easy to disassemble the first telescopic rod 2, saving time and labor costs. The secure and reliable connection and convenient installation and disassembly operations enable the water sample collection device to quickly replace the first telescopic rod 2 or undergo repair and maintenance during use, thereby improving work efficiency. This connection method can accommodate first telescopic rods 2 and fixing bases 4 of different sizes, improving the versatility and adaptability of the water sample collection device. Furthermore, the provision of the second elastic member 9 can automatically adjust the extension length of the second stopper 10 to accommodate different installation errors and wear conditions.

[0057] Furthermore, the first fixed rod 121 has a rotating end 125 and a second clamping hole 126, and the second fixed rod 32 is horizontally swung and set on the rotating end 125. After swinging, the clamping end 31 is used to be clamped and set in the adjacent second clamping hole 126. Several third telescopic rods 3 form a passage, and the sampling bucket is used to be raised and lowered in the passage.

[0058] In this embodiment, one end of the first fixed rod 121 serves as a pivoting end 125, allowing the first fixed rod 121 to rotate on the mounting base 11. A second engaging hole 126 is provided on the side of the first fixed rod 121. The shape and size of the second engaging hole 126 match the engaging end 31 of the third telescopic rod 3. One end of the second fixed rod 32 is hingedly connected to the pivoting end 125 of the first fixed rod 121, allowing the second fixed rod 32 to swing horizontally. After the third telescopic rod 3 on the second fixed rod 32 is extended and swung, its engaging end 31 can engage with the second engaging hole 126 on the adjacent first fixed rod 121. When multiple third telescopic rods 3 are connected in this manner, a passageway is formed. The diameter of this passageway is slightly larger than the diameter of the sampling bucket. The sampling bucket is connected to the first telescopic rod 2 via a sling. The sampling bucket can be raised or lowered within the passageway as the first telescopic rod 2 extends and retracts.

[0059] The design of the passageway prevents interference between the third telescopic rod 3 and the vertical first telescopic rod 2. During the raising and lowering of the sampling bucket, the passageway provides an independent space for the bucket, ensuring smooth water sampling and improving the reliability and stability of the device. The passageway formed by the multiple third telescopic rods 3 provides additional support and guidance for the sampling bucket. During the water sampling process, the sampling bucket can be raised and lowered within the passageway without shaking or shifting, further enhancing the stability of the device.
