Description

Technical Field

[0001] This utility model relates to the technical field of water quality testing equipment, and more specifically, to a rapid detection device for aquaculture diseases. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. In the process of aquaculture, in order to understand the water quality of the aquaculture environment, it is often necessary to use water quality testing devices to test the water quality. When testing water quality with existing water quality testing devices, it is first necessary to use a sampling tube to take a sample of the water body.

[0003] Existing water quality testing devices mostly involve placing the sampling tube below the water surface in aquaculture farms during the sampling process. This method is not convenient for stratified water sampling. Since there will be sediment in the aquaculture water, the suspended solids and free impurities distributed in the water at different depths are also different, resulting in inaccurate data after sampling and testing, and making it impossible to accurately assess the water quality of aquaculture farms.

[0004] A search revealed a Chinese patent with publication number CN219084451U that discloses a water quality testing device for aquaculture. This utility model uses the movement of a sleeve to drive the movement of a baffle and open the water inlet channel. Water flows into the sampling cylinder through the water inlet channel, thereby enabling water to be sampled at different depths. This facilitates the sampling and testing of water quality at different depths and improves the accuracy of the testing.

[0005] However, in actual use, the aforementioned water quality testing device, due to its large area, causes significant mixing of water at different depths during its entry into the water body, reducing the accuracy and representativeness of the tests at different depths. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rapid detection device for aquaculture diseases to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rapid detection device for aquaculture diseases includes an outer cylinder with a handle fixedly connected to its top. A sampling mechanism is located inside the outer cylinder. The sampling mechanism includes a pointed tube, one side of which is fixedly connected to the bottom of the outer cylinder. An opening (first opening) is located at the bottom of the pointed tube. Multiple openings (second openings) are located on the outer side of the outer cylinder. A servo motor is fixedly connected to the top of the outer cylinder. A rotating rod is fixedly connected to the output end of the servo motor. The outer side of the rotating rod is rotatably connected to the inner side of the outer cylinder. A thread is present at the bottom of the rotating rod. A fixing plate is rotatably connected to the bottom of the rotating rod. The outer side of the fixing plate is fixedly connected to the inner side of the outer cylinder. The thread... A threaded block is connected to the outer side of the threaded block. Two sliders are fixedly connected to the outer side of the threaded block. The outer side of the sliders is slidably connected to the inner wall of the outer cylinder. Two fixing rods are fixedly connected to the bottom of the threaded block. A rubber roller is fixedly connected to the bottom of the fixing rod. Two sealing rings are fixedly connected to the outer side of the rubber roller. The two sealing rings are symmetrically arranged on the outer side of the rubber roller. A protective box is fixedly connected to one side of the pointed tube. A water quality detection probe body is fixedly connected to the inner side of the protective box. One end of the water quality detection probe body extends into the inside of the pointed tube. A protective tube is fixedly connected to the top of the protective box. A drainage mechanism is provided on the outer side of the outer cylinder.

[0009] By adopting the above technical solution, the lifting and lowering of the rubber roller and sealing ring can form a cavity that can be opened at any time between the outer cylinder and the pointed tube. Furthermore, by using air pressure, water will not enter prematurely before the detection device reaches the specified depth. This also reduces the contact area between the detection device and the water, thus reducing the possibility of excessive mixing of the water.

[0010] As a further description of the above technical solution: the drainage mechanism includes multiple positioning blocks, one side of which is fixedly connected to the outer side of the outer cylinder, and a vent pipe is fixedly connected to the inner side of the positioning block. An air pump is connected to the top of the vent pipe, the outer side of the vent pipe extends to the inner side of the outer cylinder, and a filter screen is fixedly connected to the bottom of the vent pipe.

[0011] By adopting the above technical solution, the gas introduced into the pointed tube through the vent pipe allows the detection device to discharge the water inside without leaving the water body, so as to detect water at different depths.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up a sampling mechanism, compared with existing technologies, the conical outer surface formed by the outer cylinder and the pointed tube reduces the contact area between the detection device and the water, reduces the water flow caused, keeps the water at various depths relatively stable, improves the accuracy of the detection device in detecting water at different depths, and thus makes the detection results more representative.

[0014] By setting up a drainage mechanism, compared with existing technologies, the detection device can be discharged without leaving the water body during multiple tests at different depths. This allows for rapid detection of water at different depths without excessive agitation, thus improving water detection efficiency. Attached Figure Description

[0023] 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.

[0024] The embodiments disclosed in this application are as follows: Figure 1-7The device for rapid detection of diseases in aquaculture, as shown, includes an outer cylinder 1, with a handle 2 fixedly connected to the top of the outer cylinder 1. A sampling mechanism is provided inside the outer cylinder 1. The sampling mechanism includes a pointed tube 3, one side of which is fixedly connected to the bottom of the outer cylinder 1. An opening 4 is provided at the bottom of the pointed tube 3. Multiple openings 5 ​​are provided on the outer side of the outer cylinder 1. A servo motor 6 is fixedly connected to the top of the outer cylinder 1. A rotating rod 7 is fixedly connected to the output end of the servo motor 6. The outer side of the rotating rod 7 is rotatably connected to the inner side of the outer cylinder 1. A thread 8 is provided at the bottom of the rotating rod 7. A fixing plate 9 is rotatably connected to the bottom of the rotating rod 7. The outer side of the fixing plate 9 is fixedly connected to the inner side of the outer cylinder 1. A threaded block 10 is threadedly connected to the outer side of the threaded block 8. Two sliders 11 are fixedly connected to the outer side of the threaded block 10. The outer side of the sliders 11 is slidably connected to the inner wall of the outer cylinder 1. Two fixing rods 12 are fixedly connected to the bottom of the threaded block 10. A rubber roller 13 is fixedly connected, and two sealing rings 14 are fixedly connected to the outside of the rubber roller 13. The two sealing rings 14 are symmetrically arranged on the outside of the rubber roller 13. A protective box 15 is fixedly connected to one side of the pointed tube 3. A water quality detection probe body 16 is fixedly connected to the inside of the protective box 15. One end of the water quality detection probe body 16 extends into the inside of the pointed tube 3. A protective tube 17 is fixedly connected to the top of the protective box 15. A drainage mechanism is opened on the outside of the outer cylinder 1. The servo motor 6 drives the rotating rod 7 and the thread 8 to drive the fixed plate 9, the fixed rod 12 and the rubber roller 13, so that the rubber roller 13 and the sealing rings 14 can control the opening and closing of the second opening 5 at different depths, so that water at the depth to be detected can enter the inside of the pointed tube 3. Then, the water quality detection probe body 16 detects the water that has entered the inside of the pointed tube 3, reducing the excessive mixing of water caused by the detection device.

[0025] Reference Figure 3 , Figure 6 and Figure 7 As shown, the drainage mechanism includes multiple positioning blocks 18. One side of the positioning block 18 is fixedly connected to the outside of the outer cylinder 1. A vent pipe 19 is fixedly connected to the inside of the positioning block 18. An air pump 20 is connected to the top of the vent pipe 19. The outside of the vent pipe 19 extends to the inside of the outer cylinder 1. A filter screen 21 is fixedly connected to the bottom of the vent pipe 19. The air pump 20 supplies air to the inside of the pointed tube 3 through the vent pipe 19 and the filter screen 21, so that the water inside the pointed tube 3 can be squeezed out by the air, thereby detecting water bodies at different depths.

[0026] The working principle of this utility model is as follows: When testing the water quality of an aquaculture pond, the bottom of the outer cylinder 1 is first inserted into the water. The conical shape formed by the outer cylinder 1 and the pointed tube 3 reduces water ripples. Then, when the multiple openings 5 ​​on the outside of the pointed tube 3 reach the required testing depth, the small openings of the openings 4 and the cavity formed inside the outer cylinder 1 and the pointed tube 3 prevent water from entering the interior of the pointed tube 3 due to air pressure. Afterwards, the servo motor 6 drives the rotating rod 7 to rotate, and the rotating rod 7 and the thread 8 drive the threaded block 10 for threaded transmission. Then, the threaded block 10... Guided by the slider 11, the threaded block 10 can drive the rubber roller 13 to slide upward on the inner wall of the outer cylinder 1 through the two fixed rods 12. After the rubber roller 13 separates from the position of the multiple openings 5, the multiple openings 5 ​​are connected to the opening 4 at the bottom of the pointed tube 3, so that water can enter the interior of the pointed tube 3. Then, the servo motor 6 drives the rotating rod 7 to reverse, so that the rubber roller 13 can move back to the position of the multiple openings 5, so that the multiple openings 5 ​​are resealed. Then, the water quality detection probe body 16 quickly detects the water inside the pointed tube 3.

[0027] After the water inside the pointed tube 3 is tested, the air pump 20 is started to input air into the vent pipe 19. The air enters the inside of the pointed tube 3 through the vent pipe 19 and the filter screen 21 at the bottom. When the air enters the inside of the pointed tube 3, it floats upward. In the sealed space formed by the pointed tube 3 and the rubber roller 13, the air will gradually squeeze the water inside the pointed tube 3 out of the opening 4, so that the inside of the pointed tube 3 is vacuumed again. Then the depth of the multiple openings 5 ​​in the water can be adjusted, and the operation can be repeated to test the water at different depths.
