Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, and in particular to a sampling device for testing water quality in aquaculture. Background Technology

[0002] Aquaculture, also known as aquatic product farming, refers to the cultivation of fish or various seafood in artificially created fishponds on land for consumption.

[0003] Based on the different water quality, aquaculture can be divided into three main categories: freshwater aquaculture, saltwater aquaculture, and marine aquaculture.

[0004] In aquaculture, lake water is typically introduced into fish passages for replenishment. However, since fish have specific water quality requirements, the lake water introduced into the fish passages needs to be tested to ensure it meets the fish's needs. Before testing the lake water, it is necessary to take samples. Currently, most sampling methods involve manually taking samples from the lake water using cups. This method can only extract water from the surface of the river and cannot sample water at different depths, leading to inaccurate test results. While existing water quality testing and sampling devices can sample water at different depths, they still have some problems.

[0005] For example, Chinese Patent CN108709769B discloses a water quality testing and sampling device for lakes utilizing water resources. The purpose of this invention is to provide a water quality testing and sampling device for lakes utilizing water resources that can sample water from different locations and depths, reducing labor intensity and improving safety. Technical solution: A water quality testing and sampling device for lakes utilizing water resources includes a base plate, a mounting block, a first rotating shaft, a support plate, a placement plate, a collection box, a connecting plate, a water collection tank, a sealing ring, a baffle, a mounting box, a wireless control module, and a power supply, etc.; the mounting block is connected to the middle of the base plate, and the first rotating shaft is rotatably connected to the front of the mounting block. In this invention, the water collection tank sinks downwards when submerged in water due to the counterweight, thus enabling sampling of water from different locations and depths in the lake. This eliminates the need for manual sampling using a small boat, thereby reducing labor intensity and improving safety.

[0006] Although the aforementioned water quality sampling device solves the problem that it is inconvenient for existing manual sampling to be carried out at different locations and depths, the water quality sampling device requires multiple samplings at different depths and cannot sample water at different depths at the same time. The sampling method is cumbersome and inefficient. Therefore, this application provides a water quality testing and sampling device for aquaculture to meet the needs. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a sampling device for water quality testing in aquaculture to solve the problem that the existing method of sampling water at different depths requires multiple samplings, which is cumbersome and inefficient.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A water quality testing and sampling device for aquaculture includes an installation sleeve with multiple through holes at one end. A connecting rod is fixedly connected inside the installation sleeve, a connecting sleeve is fixedly connected at one end of the connecting rod, a first connecting line is fixedly connected at one end of the connecting sleeve, and a sampling unit for sampling at multiple depths is provided inside the installation sleeve.

[0010] The sampling unit includes a mounting block slidably connected within the mounting sleeve. A first float is mounted on the mounting block, and a second float is mounted on one side of the first float. Multiple second connecting lines are fixedly connected to the mounting block. One end of each second connecting line passes through the first and second floats and is fixedly connected to a push block, which is slidably connected to the first connecting line. Multiple connecting blocks are fixedly connected to the connecting sleeve. Multiple first through slots are formed on the connecting blocks, and multiple second sliding grooves are formed on one side of each connecting block. Limiting grooves are formed in the second sliding grooves. A water-taking sleeve is fitted onto the connecting sleeve. Multiple second through slots are formed at both ends of the water-taking sleeve. Multiple telescopic rods are fixedly connected to both ends of the water-taking sleeve. Springs are fitted onto the telescopic rods, and limiting beads are fixedly connected to the output ends of the telescopic rods, which are slidably connected within the second sliding grooves. A pair of third sliding grooves are formed on the water-taking sleeve, and a pair of sliders are fixedly connected to the mounting block, which are slidably connected within the third sliding grooves.

[0011] Preferably, the first through slot and the second through slot are adapted to each other, and the number of the first through slot and the number of the second through slot are both four.

[0012] Preferably, one end of the mounting sleeve is a tapered structure, and the through hole is formed on the tapered structure.

[0013] Preferably, the mounting sleeve has multiple first sliding grooves, and the mounting block has multiple limiting blocks fixedly connected to it, with the limiting blocks slidably connected to the first sliding grooves.

[0014] Preferably, the number of the second connecting lines is four.

[0015] Preferably, the limiting bead is adapted to the limiting groove.

[0016] Preferably, the number of connecting blocks is four, the number of water intake sleeves is two, and one water intake sleeve is sandwiched between two connecting blocks.

[0017] Preferably, one end of the spring is fixedly connected to the telescopic rod, and the other end of the spring is fixedly connected to the limiting bead.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, by setting up a sampling unit, when using the water quality testing sampling device, the device is first placed in the water, and one end of the first connecting line is held in the hand. As water flows into the device through the through hole, the sampling unit samples water at different depths, achieving the purpose of sampling water at different depths at once, replacing the existing method of multiple round trips for sampling, improving sampling efficiency and making it highly practical.

[0020] When the water quality testing and sampling device is placed in the water, as the mounting sleeve descends, the first and second channels connect, filling the water-collecting sleeve with water. Then, under the buoyancy of the first float, the mounting block moves, and through the cooperation of the slider and the third sliding groove, one of the water-collecting sleeves rotates. This causes the second and first channels to misalign, creating a sealed space within the water-collecting sleeve, thus collecting water. As the water-collecting sleeve rotates, a limiting bead slides within the second sliding groove until it moves into the limiting groove. Under the action of a spring, the water-collecting sleeve remains stationary, maintaining an internally sealed state, thus collecting water from the upper layers. Then, as the device continues to sink, The second connecting line moves underwater, while the second float remains on the surface until the device descends to a certain depth. At this point, the second float moves to the position of the push block and comes into contact with it. As the device continues to sink, the push block sinks via the first connecting line, which in turn drives the second float to sink. The cooperation of the first and second floats increases buoyancy, causing the mounting block to move onto the second water intake sleeve. Through the cooperation of the slider and the [other component], the second water intake sleeve rotates, thus closing and achieving the purpose of collecting deeper water. This allows for the collection of water at different depths, replacing the existing sampling method that requires multiple round trips, improving sampling efficiency, and offering high practicality.

[0037] like Figure 1 As shown, an embodiment of the present invention provides a water quality testing and sampling device for aquaculture, including a mounting sleeve 1. One end of the mounting sleeve 1 has multiple through holes 3. One end of the mounting sleeve 1 has a conical structure, and the through holes 3 are located on the conical structure. A connecting rod 4 is fixedly connected inside the mounting sleeve 1. One end of the connecting rod 4 is fixedly connected to a connecting sleeve 5, and one end of the connecting sleeve 5 is fixedly connected to a first connecting line 6. A sampling unit 2 for sampling at multiple depths is provided inside the mounting sleeve 1. When using this water quality testing and sampling device, the device is first placed in the water, and one end of the first connecting line 6 is held in the hand. As water flows into the device through the through holes 3, the sampling unit 2 samples water at different depths, achieving the purpose of sampling water at different depths at once. This replaces the existing method of multiple round trips for sampling, improving sampling efficiency and practicality.

[0038] like Figure 1-6 As shown, the sampling unit 2 includes a mounting block 8 slidably connected to the mounting sleeve 1. The mounting sleeve 1 has multiple first sliding grooves 7. Multiple limiting blocks are fixedly connected to the mounting block 8, and the limiting blocks are slidably connected to the first sliding grooves 7. A first float 9 is provided on the mounting block 8, and a second float 10 is provided on one side of the first float 9. Multiple second connecting lines 11 are fixedly connected to the mounting block 8, with four second connecting lines 11. One end of each second connecting line 11 passes through the first float 9 and the second float 10 and is fixedly connected to a push block 12, which is slidably connected to the first connecting line 6. Multiple connecting blocks 13 are fixedly connected to the connecting sleeve 5. Multiple first through grooves 14 are provided on the connecting block 13, and multiple second sliding grooves 15 are provided on one side of the connecting block 13. Limiting grooves 16 are provided on the second sliding grooves 15. A water-taking sleeve 17 is sleeved on the connecting sleeve 5. Multiple second through slots 18 are provided at both ends of the cylinder 17. Multiple telescopic rods 19 are fixedly connected to both ends of the water intake sleeve 17. Springs 20 are sleeved on the telescopic rods 19. Limiting beads 21 are fixedly connected to the output end of the telescopic rods 19, and the limiting beads 21 are slidably connected in the second slide groove 15. The limiting beads 21 are adapted to the limiting groove 16. One end of the spring 20 is fixedly connected to the telescopic rod 19, and the other end of the spring 20 is fixedly connected to the limiting beads 21. A pair of third slide grooves 22 are provided on the water intake sleeve 17. A pair of sliders are fixedly connected to the mounting block 8, and the sliders are slidably connected in the third slide grooves 22. The first through slot 14 and the second through slot 18 are adapted to each other, and there are four of each of the first through slot 14 and the second through slot 18. There are four connecting blocks 13 and two water intake sleeves 17. One water intake sleeve 17 is clamped between two connecting blocks 13.

[0039] When the water quality testing and sampling device is placed in the water, as the mounting sleeve 1 descends, the first through groove 14 and the second through groove 18 connect, filling the water intake sleeve 17 with water. Then, under the buoyancy of the first float 9, the mounting block 8 moves. Through the cooperation of the slider and the third sliding groove 22, one of the water intake sleeves 17 rotates, causing the second through groove 18 to misalign with the first through groove 14. This creates a sealed space within the water intake sleeve 17, achieving the purpose of water collection. As the water intake sleeve 17 rotates, the limiting bead 21 slides within the second sliding groove 15 until it moves into the limiting groove 16. Under the action of the spring 20, the water intake sleeve 17 remains stationary, maintaining an internally sealed state, thus collecting water from the uppermost layer. Then, as the device continues to draw water... As the device descends, the second connecting line 11 moves underwater, while the second float 10 remains on the surface until it reaches a certain depth. At this point, the second float 10 moves to the position of the push block 12 and comes into contact with it. As the device continues to descend, the first connecting line 6 drives the push block 12 to descend, which in turn drives the second float 10 to descend. With the cooperation of the first float 9 and the second float 10, the buoyancy increases, causing the mounting block 8 to move onto the second water intake sleeve 17. Through the cooperation of the slider and 23, the second water intake sleeve 17 rotates, thus closing the second water intake sleeve 17 and achieving the purpose of collecting deeper water. This allows for the collection of water at different depths, replacing the existing sampling method that requires multiple round trips, improving sampling efficiency, and increasing practicality.

[0040] The technical solution provided by this invention is that when using the water quality testing and sampling device, the device is first placed in the water, and one end of the first connecting line 6 is held in the hand. As water flows into the device through the through hole 3, the sampling unit 2 samples water at different depths, achieving the purpose of sampling water at different depths at once. This replaces the existing method of multiple round trips for sampling, improves sampling efficiency, and has high practicality.

[0041] When the water quality testing and sampling device is placed in the water, as the mounting sleeve 1 descends, the first through groove 14 and the second through groove 18 connect, filling the water intake sleeve 17 with water. Then, under the buoyancy of the first float 9, the mounting block 8 moves. Through the cooperation of the slider and the third sliding groove 22, one of the water intake sleeves 17 rotates, causing the second through groove 18 to misalign with the first through groove 14. This creates a sealed space within the water intake sleeve 17, achieving the purpose of water collection. As the water intake sleeve 17 rotates, the limiting bead 21 slides within the second sliding groove 15 until it moves into the limiting groove 16. Under the action of the spring 20, the water intake sleeve 17 remains stationary, maintaining an internally sealed state, thus collecting water from the uppermost layer. Then, as the device continues to draw water... As the device descends, the second connecting line 11 moves underwater, while the second float 10 remains on the surface until it reaches a certain depth. At this point, the second float 10 moves to the position of the push block 12 and comes into contact with it. As the device continues to descend, the first connecting line 6 drives the push block 12 to descend, which in turn drives the second float 10 to descend. With the cooperation of the first float 9 and the second float 10, the buoyancy increases, causing the mounting block 8 to move onto the second water intake sleeve 17. Through the cooperation of the slider and 23, the second water intake sleeve 17 rotates, thus closing the second water intake sleeve 17 and achieving the purpose of collecting deeper water. This allows for the collection of water at different depths, replacing the existing sampling method that requires multiple round trips, improving sampling efficiency, and increasing practicality.
