Description

Technical Field

[0001] This utility model relates to the field of aquatic fish disease prevention and detection technology, specifically to a water sample collection and adjustment device for aquatic fish disease prevention and detection. Background Technology

[0002] To develop aquaculture, regular monitoring of fish diseases is necessary. Therefore, water samples are collected for testing. Aquatic fish disease prevention and water sample testing are crucial aspects of aquaculture, involving water quality monitoring, pathogen diagnosis, and disease control. For example, a water sample collection device for water quality testing (publication number CN220231126U) specifically relates to the field of water quality testing. It includes a first sampling bottle with a connecting column fixedly connected to its upper end. A second sampling bottle is fixedly connected to the upper end of the connecting column, and the outer wall of the second sampling bottle is fixedly connected to... The device has a layered mechanism, which includes a slide rail, an adjusting plate, an electric switch, a water pressure sensor, a slide rod, a sealing cover, a first sealing ring, a second sealing ring, a spring, and a fixing block. The water pressure sensor is fixedly connected to the upper end of the slide rail, and the electric switch is fixedly connected to the outer wall of the slide rail. This layered mechanism allows for simultaneous sampling of water at different depths. Upon reaching the bottom, the first sampling bottle collects the water. During the ascent, the water flow pushes the adjusting plate downwards, allowing for simultaneous sampling at different depths and reducing the workload of repeatedly placing and retrieving the sampling device. However, this water sampling device for water quality testing still has the following drawbacks in practical use: Traditional water sampling and conditioning devices mostly have only a single sample storage space. When it is necessary to collect water samples from different locations or depths, the previously collected samples need to be poured out and re-collected. However, after pouring out the samples, residues remain in the sampling device, causing water samples from different locations to mix and affecting subsequent testing. Furthermore, the liquid in the collected water samples may contain other microorganisms, which are prone to sedimentation when stored inside the sampling device. The device lacks a structure to maintain its fluctuation. To address these issues, there is an urgent need for innovative designs based on existing water sampling and conditioning devices. Utility Model Content

[0003] The purpose of this invention is to provide a water sample collection and adjustment device for the prevention and control of aquatic fish diseases, in order to solve the problem that traditional water sample collection and adjustment devices mentioned in the background art mostly only have a single sample storage space during sampling, and the collected water sample is prone to sedimentation when stored inside the sampling device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water sample collection and adjustment device for the prevention and control of aquatic fish diseases, comprising a collection tube, the top of the collection tube being threadedly connected to the bottom of a support rod, and a movable tube being rotatably sleeved on the outer side of the support rod, the bottom of the movable tube being connected to the collection tube through an adjustment mechanism, and the adjustment mechanism being used to switch between different liquid storage chambers. It also includes: a partition plate, fixed inside the collection tube, with connection holes reserved at equal angles on the outer side of the collection tube, and a liquid outlet valve provided at the bottom of the collection tube; the partition plate divides the liquid storage chamber into four equal parts. An anti-sedimentation component is disposed inside the partition plate. The anti-sedimentation component is used to prevent water sample from settling in the storage chamber. The partition plate has an "X" shaped cross-section.

[0005] Preferably, the adjustment mechanism includes a connecting rod fixed to the bottom side of the movable cylinder, and a sleeve plate is connected to the end of the connecting rod away from the movable cylinder. The sleeve plate is rotatably fitted onto the upper end of the collection cylinder, and the sleeve plate can be driven to rotate synchronously by the connecting rod when the movable cylinder is rotated.

[0006] Preferably, the number of connecting rods and scale bars are equal, and the scale bars are fixed to the top of the collection tube. The connecting rods and scale bars are distributed at equal angles, and the connecting rods can coincide with the corresponding scale bars every 45° of rotation.

[0007] Preferably, the side of the sleeve is provided with a liquid inlet hole, and a filter screen is fixed inside the liquid inlet hole. The liquid inlet hole and the connection hole are at the same height, and the liquid flows into the liquid storage chamber through the liquid inlet hole and the connection hole.

[0008] Preferably, the anti-sedimentation component includes a movable rod extending through the top of the collection tube, and the movable rod and the collection tube are elastically slidably connected. A piston block is connected to the bottom of the movable rod, and when the movable rod is pressed, it can drive the piston block to slide in the fixed cavity.

[0009] Preferably, a fixed cavity is provided on the partition plate on the outer side of the piston block, and the edge of the piston block slides in contact with the inner wall of the fixed cavity. The fixed cavity is connected to the connecting cavity through the gas supply channel. When the piston block descends, the gas in the fixed cavity can be squeezed into the connecting cavity through the gas supply channel.

[0010] Preferably, the gas delivery channel and the connecting cavity are set at equal angles within the partition plate, and the side of the partition plate is provided with fixing holes at equal intervals, and a rubber sheet is pasted on the inner side of the fixing hole. When gas enters the connecting cavity, it can cause the rubber sheet to expand.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the aquatic fish disease prevention and control water sample collection and adjustment device is equipped with multiple sample storage spaces, which facilitates the storage of water samples from different locations or depths, avoids mixing between different water samples, and can keep the water sample in a fluctuating state after sampling to prevent sedimentation or adhesion to the wall from affecting the accuracy of the test. The specific details are as follows: 1. When the inlet is between the two connecting holes, the storage chamber is in a closed state. When sampling, rotating the movable cylinder drives the sleeve to rotate synchronously through the connecting rod. After rotating 45°, the connecting rod is aligned with the scale bar, thereby aligning the inlet with the connecting hole, so that the liquid can enter the corresponding storage chamber. Furthermore, when water samples need to be collected from different locations or depths, the sleeve is first rotated to align the inlet hole with the connection holes at other locations. Different water samples are stored in different storage chambers, which can prevent them from mixing and affecting the test results. 2. By pressing the movable rod, the piston block is driven to descend, squeezing the gas in the fixed cavity and transmitting it to the connecting cavity through the gas delivery channel. When the gas enters the connecting cavity, it can cause the rubber sheet to expand. The expansion causes the water sample in the storage cavity to fluctuate, preventing sedimentation. Furthermore, continuous pressure on the movable rod can achieve continuous fluctuation, and when the support rod is connected to the collection tube, the support rod's contact with the movable rod can cause it to retract into the collection tube, thus not affecting the sampling work.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-6 The present invention provides the following technical solution: Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a water sample collection and adjustment device for aquatic fish disease prevention and control detection, comprising a collection cylinder 1, the top of which is threadedly connected to the bottom of a support rod 2, and a movable cylinder 3 rotatably sleeved on the outer side of the support rod 2. The bottom of the movable cylinder 3 is connected to the collection cylinder 1 via an adjustment mechanism, which is used to switch between different storage chambers 11 for liquid storage; it also includes: a partition plate 10, fixed inside the collection cylinder 1, with connection holes 9 pre-drilled at equal angles on the outer side of the collection cylinder 1, and a liquid outlet valve 12 provided at the bottom of the collection cylinder 1; the partition plate 10 divides the storage chamber 11 into four equal parts; and an anti-sedimentation component, disposed inside the partition plate 10, which is used to prevent water sample sedimentation in the storage chamber 11. The partition plate 10 has an "X" shaped cross-section.

[0016] Existing water sampling and conditioning devices mostly have only a single sample storage space during sampling. When it is necessary to collect water samples from different locations or depths, the previously collected samples need to be poured out and re-collected. However, residue remains in the sampling device after pouring out the samples, causing mixing of water samples from different locations and affecting subsequent testing. Figures 1-4As shown, the adjustment mechanism includes a connecting rod 4 fixed to the bottom side of the movable cylinder 3, and a sleeve 5 connected to the end of the connecting rod 4 away from the movable cylinder 3, and the sleeve 5 is rotatably fitted onto the upper end of the collection cylinder 1; the number of connecting rods 4 and scale bars 6 are equal, and the scale bars 6 are fixed to the top of the collection cylinder 1, and the connecting rods 4 and scale bars 6 are distributed at equal angles; a liquid inlet hole 7 is opened on the side of the sleeve 5, and a filter screen 8 is fixed inside the liquid inlet hole 7, and the height of the liquid inlet hole 7 and the connecting hole 9 are the same; when the liquid inlet hole 7 on the sleeve 5 is between the two connecting holes 9, the liquid storage chamber 11 is in a closed state; when it is necessary to store a sample in one of the liquid storage chambers 11, the movable cylinder is rotated. 3. The connecting rod 4 drives the sleeve 5 to rotate synchronously. After rotating 45°, the connecting rod 4 and the scale bar 6 are aligned, and the liquid inlet 7 and the connecting hole 9 are aligned. When the collection tube 1 is placed underwater, the liquid can enter the corresponding storage chamber 11 through the liquid inlet 7 and the connecting hole 9. When it is necessary to collect water samples from different positions or depths, first rotate the sleeve 5 to make the liquid inlet 7 correspond to the connecting hole 9 in other positions, and then put the collection tube 1 underwater to complete the sampling. Different water samples are stored in different storage chambers 11 to avoid mixing and affecting the test results. When needed, the water sample can be poured out through the liquid outlet valve 12.

[0017] Example 2: Because the collected water sample contains other microorganisms in the storage liquid, it is prone to precipitation when stored inside the sampling device, lacking a structure to maintain its fluctuation. Therefore, this example uses the following technical solution, such as... Figure 3 and Figures 5-6As shown, the anti-sedimentation assembly includes a movable rod 13 extending through the top of the collection cylinder 1, and the movable rod 13 and the collection cylinder 1 are elastically slidably connected. A piston block 14 is connected to the bottom of the movable rod 13. A fixing cavity 15 is provided on the partition plate 10 outside the piston block 14, and the edge of the piston block 14 slides against the inner wall of the fixing cavity 15. The fixing cavity 15 is interconnected with a connecting cavity 17 via a gas delivery channel 16. The gas delivery channel 16 and the connecting cavity 17 are evenly spaced within the partition plate 10, and fixing holes 18 are evenly spaced on the side of the partition plate 10. Rubber sheets 19 are attached to the inner side of the fixing holes 18. After sampling, the support rod 2 can be rotated to separate it from the collection cylinder 1. When the bottom of the support rod 2 no longer contacts the movable rod... At 13 o'clock, the spring elasticity drives the movable rod 13 and piston block 14 to rise beyond the outside of the collection tube 1. Then, by pressing the movable rod 13, the piston block 14 is driven to descend. The piston block 14 can squeeze the gas in the fixed cavity 15 and transmit it to the connecting cavity 17 through the gas delivery channel 16. When the gas enters the connecting cavity 17, it can drive the rubber sheet 19 to expand. The expansion causes the water sample in the liquid storage cavity 11 to fluctuate, preventing sedimentation and improving the accuracy of subsequent detection. Continuous fluctuation can be achieved by continuously pressing the movable rod 13. When the support rod 2 is connected to the collection tube 1, the support rod 2 can push the movable rod 13 into the inside of the collection tube 1 through its contact, so as not to affect the sampling work.

[0018] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
