Description

Technical Field

[0001] The invention relates to the field of water quality detection, in particular to a water quality detection trolley for aquatic seedling cultivation. Background Art

[0002] Water quality testing and seedling status monitoring are two key operations in aquaculture. By testing, analyzing, and adjusting water quality, we can provide a suitable growth environment for aquacultured organisms. Continuous seedling monitoring provides timely information on aquacultured organisms' feeding habits, activity status, and disease risks. Mobile testing stations seamlessly integrate water quality testing and seedling monitoring to ensure the healthy growth and development of aquacultured organisms, making their application particularly important.

[0003] Most aquatic seedlings nowadays are raised in multiple independent breeding ponds to reduce breeding risks. Therefore, when testing the water quality in the breeding ponds, they need to be tested one by one. The traditional testing method is to take samples of water from each breeding pond and send them to the laboratory for testing. Although this method is simple, it is prone to the risk of contamination during the transfer of water samples, resulting in inaccurate test results. Summary of the Invention

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] Reference Figure 1-9 As shown, a method for detecting water quality of aquatic seedlings includes the following steps:

[0033] Step 1: Move and position the water quality detection trolley: Control the mobile platform 1 of the water quality detection trolley to move to the side of the breeding pond so that the spiral hose 28 can touch the liquid surface of the corresponding breeding pond when moving downward; the movement of the water quality detection trolley can also be achieved by wire control, radio remote control, or program control.

[0034] See also Figure 2-9 The water quality testing cart includes a mobile platform 1, the lower portion of which is provided with a roller 2 for driving its movement. The mobile platform 1 is also provided with a receiving structure capable of intermittent movement, which is connected to the roller 2. The receiving structure includes two sets of conveyor pulleys 11 symmetrically mounted on the mobile platform 1. Two conveyor belts 12 are sleeved between the two sets of conveyor pulleys 11, and a plurality of receiving test tubes 13 are rotatably mounted on the conveyor belts 12. The conveyor pulleys 11 are connected to a bevel gear set 9 located between the mobile platform 1 and the rotating shaft of the roller 2 via a second belt 10.

[0035] See also Figure 2-9 The bevel gear assembly 9 includes a first bevel gear coaxially fixedly connected to the rotating shaft of the roller 2, and a second bevel gear meshing with the first bevel gear and rotatably mounted on the movable platform 1. The rotating shaft of the second bevel gear passes through the movable platform 1 and is connected to one of the conveyor pulleys 11 via a second belt 10. To prevent excessive loss of water sample due to shaking of the receiving test tube 13 during movement, the diameter of the first bevel gear is smaller than that of the second bevel gear. This not only reduces the displacement of the receiving test tube 13 during movement of the movable platform 1, but also reduces the speed difference of the receiving test tube 13 during movement, thereby reducing its acceleration during movement and minimizing water sample loss.

[0036] When roller 2 rotates, it drives the mobile platform 1 to move, and at the same time, drives one of the conveyor pulleys 11 to rotate through the bevel gear set 9 and the second belt 10, causing the conveyor belt 12 mounted on the two conveyor pulleys 11 to move, thereby causing the receiving test tube 13 to move. Each conveyor pulley 11 is composed of two pulleys at different heights, and a conveyor belt 12 is mounted on the pulleys at different heights. The upper and lower ends of the receiving test tube 13 are fixedly connected to the conveyor belt 12 to prevent the receiving test tube 13 from tilting during movement, which may cause the water sample to be lost.

[0037] See Figure 7 The roller 2 is further connected to an intermittent output assembly mounted on the movable platform 1, which is in turn connected to a pumping mechanism mounted on the movable platform 1. The intermittent output assembly includes a baffle 3 fixedly mounted on the movable platform 1. A drive device 4 is fixedly mounted on the baffle 3, and an output shaft of the drive device 4 passes through the baffle 3 and is connected to a Maltese cross movement structure mounted on the baffle 3.

[0038] The Maltese cross movement structure is connected to the rotating shaft of the roller 2 via a first belt 8 and to the pumping mechanism via a third belt 14. The Maltese cross movement structure includes a driving wheel 5 rotatably mounted on the baffle 3 and connected to the output shaft of the drive device 4; a first driven wheel 6 and a second driven wheel 7 rotatably mounted on the baffle 3, adapted to the driving wheel 5. The first driven wheel 6 is connected to the rotating shaft of the roller 2 via the first belt 8, and the second driven wheel 7 is connected to the pumping mechanism via the third belt 14.

[0039] When the drive device 4 is operating, it rotates the connected driving wheel 5, which cooperates with the first and second driven wheels 6, 7, respectively. When the driving wheel 5 cooperates with the first driven wheel 6, the first driven wheel 6 rotates. At this time, the second driven wheel 7 does not rotate. As the first driven wheel 6 rotates, it drives the roller 2 via the first belt 8, causing the movable platform 1 to move. Simultaneously, under the action of the bevel gear set 9 and the second belt 10, the conveyor pulley 11 rotates, and the conveyor belt 12 moves, driving the receiving test tube 13 to move. When the driving wheel 5 cooperates with the second driven wheel 7, the first driven wheel 6 does not rotate. The second driven wheel 7 drives the pumping mechanism via the third belt 14, completing the pumping of water samples into the receiving test tube 13 and testing the water samples.

[0040] See Figure 2-9 , the pumping mechanism is used to pump the sample to be tested into the receiving structure, and the pumping mechanism is connected to the detector 30 for testing the sample in the receiving structure through the connecting plate 29. The pumping mechanism includes a mounting plate 15 and a vertical plate 16 vertically mounted on the movable platform 1 and parallel to each other, and a pumping assembly is provided on the vertical plate 16. The pumping assembly is connected to a spiral hose 28 through a one-way valve, and the spiral hose 28 is connected to a lifting assembly provided between the mounting plate 15 and the vertical plate 16. The lifting assembly is connected to the second driven wheel 7 through the third belt 14, and a trigger assembly is also provided between the mounting plate 15 and the vertical plate 16. The trigger assembly is connected to the pumping assembly and is connected to the lifting assembly through the fourth belt 17.

[0041] The pumping assembly includes a piston cylinder 27 fixedly mounted on the vertical plate 16, a piston disc 25 sealingly and slidingly mounted in the piston cylinder 27, and a reset structure connecting the trigger assembly and the piston disc 25. The piston cylinder 27 is connected to and communicates with a conduit located just above the receiving test tube 13. The reset structure includes a vertical rod 24 fixedly connected to the piston disc 25 and movably extending through the piston cylinder 27, and a spring 26 sleeved on the vertical rod 24. The end of the vertical rod 24 away from the piston disc 25 is connected to the trigger assembly. One end of the spring 26 is connected to the piston disc 25, and the other end is connected to the inner wall of the piston cylinder 27. The lifting assembly includes a turntable 18 rotatably mounted on the mounting plate 15. A pulley 19 is rotatably mounted on the turntable 18, and the pulley 19 is in rolling connection with the lifting member 20 located on the vertical plate 16. The lifting member 20 is connected to the spiral hose 28 via a connecting rod 21 extending through the vertical plate 16. The vertical plate 16 is provided with two chute slots, one of which is fixedly mounted with a guide rod. The connecting rod 21 is slidably mounted on the guide rod. The turntable 18 is connected to the second driven wheel 7 via the third belt 14. The trigger assembly includes a crossbar 23 fixedly connected to the vertical rod 24 and extending through another of the chute slots; and a rotating member 22 rotatably mounted on the mounting plate 15 and connected to the turntable 18 via the fourth belt 17. A protrusion is fixedly mounted on the rotating member 22, which mates with the crossbar 23, which is connected to the connecting plate 29.

[0042] When the driving wheel 5 cooperates with the second driven wheel 7, the second driven wheel 7 drives the turntable 18 to rotate through the third belt 14. At the same time, during the rotation of the turntable 18, the rotating member 22 is driven to rotate through the fourth belt 17. During the rotation of the turntable 18, the connecting rod 21 is driven downward by the cooperation of the pulley 19 and the lifting member 20, and the spiral hose 28 is immersed in the water of the breeding pond. When the rotating member 22 rotates half a circle, the vertical rod 24 and the piston disc 25 are driven to move downward, and the spring 26 is stretched; the protrusion on the rear rotating member 22 is separated from the cross bar 23, the spring 26 is reset, and the piston disc 25 is driven to move upward, and the water sample in the breeding pond is sucked into the piston cylinder 27 through the spiral hose 28. When the second driven wheel 7 rotates next time, the piston disc 25 pumps the water sample in the piston cylinder 27 into the receiving test tube 13.

[0043] It should be noted that when the driving wheel 5 rotates one circle, the No. 1 driven wheel 6 and the No. 2 driven wheel 7 both rotate a quarter of a circle, and when the No. 2 driven wheel 7 rotates a quarter of a circle, the rotating member 22 and the turntable 18 need to rotate one circle; therefore, the diameter of the driving pulley of the No. 3 belt 14 is four times the diameter of its driven pulley, wherein the driving pulley of the No. 3 belt 14 is coaxially fixedly connected to the No. 2 driven wheel 7, and the driven pulley is coaxially fixedly connected to the turntable 18.

[0044] Step 2: Drive the receiving test tube: The inspector controls the driving device 4 to rotate, causing the receiving test tube 13 to move; in step 2, the driving device 4 drives the driving wheel 5 connected thereto to rotate, and the driving wheel 5 cooperates with the second driven wheel 7 to drive the roller 2 to rotate, so that the movable platform 1 moves, and at the same time, the roller 2 drives the conveyor pulley 11 to rotate through the bevel gear set 9 and the second belt 10, thereby driving the conveyor pulley 11 to move.

[0045] Specifically, when the driving wheel 5 rotates one circle, it cooperates with the No. 1 driven wheel 6 and the No. 2 driven wheel 7, respectively, and causes the No. 1 driven wheel 6 and the No. 2 driven wheel 7 to rotate a quarter of a circle. When the No. 1 driven wheel 6 rotates, the No. 2 driven wheel 7 stops rotating. When the No. 2 driven wheel 7 rotates, the No. 1 driven wheel 6 stops rotating. When the No. 1 driven wheel 6 rotates a quarter of a circle, it drives the roller 2 to rotate through the No. 1 belt 8, causing the movable platform 1 to move. When the movable platform 1 moves, the conveyor pulley 11 is driven through the bevel gear set 9 and the No. 2 belt 10, causing the conveyor belt 12 to move, causing the receiving test tube 13 to move.

[0046] Step 3: Collecting water samples: the driving wheel 5 is separated from the second driven wheel 7, the mobile platform 1 stops rotating, and the rear driving wheel 5 cooperates with the first driven wheel 6 to drive the turntable 18 and the rotating member 22 to rotate. During the process of rotating the turntable 18 half a circle, the pulley 19 and the lifting member 20 cooperate to drive the connecting rod 21 to move downward, and the spiral hose 28 is immersed in the water of the aquaculture pond; when the rotating member 22 rotates half a circle, the vertical rod 24 and the piston disc 25 are driven to move downward, and the spring 26 is stretched. The protrusion on the rear rotating member 22 is separated from the cross bar 23, and the spring 26 is reset, driving the piston disc 25 to move upward, and the water sample in the aquaculture pond is sucked into the piston cylinder 27 through the spiral hose 28; the turntable 18 and the rotating member 22 continue to rotate half a circle to lift the connecting rod 21;

[0047] Specifically, when the No. 2 driven wheel 7 rotates a quarter of a circle, the turntable 18 is driven to rotate one circle through the No. 3 belt 14. At the same time, during the process of the turntable 18 rotating one circle, it drives the rotating part 22 to rotate one circle through the No. 4 belt 17. During the process of the turntable 18 rotating half a circle, the connection rod 21 is driven downward by the cooperation of the pulley 19 and the lifting part 20, and the spiral hose 28 is immersed in the water of the breeding pond. When the rotating part 22 rotates half a circle, the vertical rod 24 and the piston disc 25 are driven downward by the cooperation of the protrusion and the cross bar 23, and the spring 26 is stretched. After that, the protrusion on the rotating part 22 separates from the cross bar 23, the spring 26 resets, and drives the piston disc 25 to move upward, so that negative pressure is generated in the piston cylinder 27, and the water sample in the breeding pond is sucked into the piston cylinder 27 through the spiral hose 28.

[0048] Step 4: Switch the driving wheel: the driving wheel 5 separates from the first driven wheel 6 and contacts the second driven wheel 7, and repeats the above step 2;

[0049] Step 5. Complete the water sample test of a single breeding pond: the driving wheel 5 cooperates with the No. 1 driven wheel 6 again, and when the cross bar 23 moves downward, the water pump in the piston cylinder 27 is sent to the receiving test tube 13. At the same time, the detector 30 follows the cross bar 23 to move downward, and detects the water sample in the receiving test tube 13 to achieve water quality testing of a breeding pond; specifically: when the protrusion drives the cross bar 23 to move downward, the detector 30 is driven downward by the connecting plate 29, and the detection head of the detector 30 is immersed in the water sample in the receiving test tube 13, completing the water sample test of a single breeding pond.

[0050] Step 6. Complete the water sample testing of all aquaculture ponds one by one: Repeat the above steps one to five to complete the water sample testing of all aquaculture ponds one by one.
