Description

Technical Field

[0001] This invention relates to the field of fishery water quality testing technology, specifically to an automatic monitoring device for aquaculture water quality. Background Technology

[0002] Aquaculture, also known as fish farming, encompasses various models including extensive farming, intensive farming, and high-density intensive farming. Given the current scarcity of resources, intensive farming has been widely promoted due to its high efficiency and other advantages. Intensive farming typically involves artificially creating fishponds to raise fish in order to meet market demands.

[0003] In intensive aquaculture, due to the high stocking density, fish metabolites and leftover feed tend to accumulate, and water quality changes more rapidly and complexly, significantly impacting fish growth, health, and aquaculture efficiency. Therefore, it is necessary to conduct regular water quality testing to promptly identify water quality problems and take corresponding measures for adjustment and improvement.

[0004] Currently, water quality monitoring largely relies on water quality sensors to detect various indicators. However, in practical applications, aquatic plants growing on the bottom often become obstacles. When the water quality sensor moves downwards, the aquatic plants not only hinder its normal descent, but some plants may also attach to the surface of the sensor, interfering with the accuracy of the detection data and thus affecting the reliability of the water quality test results. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic monitoring device for aquaculture water quality. This invention solves the problem that existing devices are easily affected by aquatic plants, leading to inaccurate detection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic water quality monitoring device for aquaculture, comprising:

[0007] A cylindrical container, with a floating plate and a support plate fixedly installed at each end of the cylindrical container, respectively.

[0008] A drive assembly, mounted on a support plate, includes a first circular rod for limiting the vertical movement of the detection assembly;

[0009] The detection component includes several water quality sensors that collect water quality parameters;

[0010] The actuating mechanism is located below the moving path of the detection component and includes a spreading component sleeved on the outside of the first round rod; when the detection component is driven downward by the driving component, the spreading component is squeezed by the detection component and generates radial expansion motion.

[0011] The spreading assembly includes a floating block and a support plate. Several first connecting rods are evenly and rotatably installed on the outer wall of the floating block. Several second connecting rods are evenly and rotatably installed on the upper surface of the support plate. The second connecting rods are rotatably connected to the first connecting rods. A buckle is installed on the outer wall of the second connecting rod, and an elastic rope is sleeved inside the buckle.

[0012] Preferably, a controller and a battery are installed on the upper surface of the support plate, a plurality of support rods are evenly installed on the upper surface of the floating plate, a solar panel is installed on the upper surface of the support rods, and an opening is provided on the lower surface of the floating plate.

[0013] Preferably, the drive assembly includes a servo motor, which is fixedly mounted on a support plate. A second round rod is fixedly mounted on the output shaft of the servo motor. Retaining rings are symmetrically mounted on the outer wall of the second round rod. A support block is rotatably mounted on the end of the second round rod away from the servo motor. The lower end face of the support block is fixedly mounted on the support plate. Pull ropes are symmetrically wound around the outer wall of the second round rod.

[0014] Preferably, the detection component includes a disc, a gravity block is fixedly installed on the lower end face of the disc, a water quality sensor is installed on the lower end face of the disc, air tubes are symmetrically installed on both sides of the water quality sensor, the air tubes pass through the disc, and the disc is installed at the end of the pull rope.

[0015] Preferably, a plurality of ball bearings are installed at the point where the gravity block abuts against the first round rod.

[0016] Preferably, a sealing disc is slidably mounted on the outer wall of the first round rod, a spring is mounted on the upper end face of the sealing disc, and the side of the spring away from the sealing disc is mounted on a support plate.

[0017] Preferably, the support plate is fixedly installed on the outer wall of the first round rod.

[0018] Preferably, the floating block is slidably mounted on the outer wall of the first round rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] I. This invention is equipped with a toggle mechanism. When the gravity block presses against the floating block, the floating block moves downward on the first round rod and presses against the first connecting rod. The first connecting rod presses against the second connecting rod. At this time, the first connecting rod rotates outward about the connection between the first connecting rod and the floating block, and the second connecting rod rotates outward about the connection between the second connecting rod and the support plate. Simultaneously, the second connecting rod drives the elastic rope to move outward through the buckle. The elastic rope gradually increases in size, pushing away the aquatic plants on the outside. At this time, the water quality sensor can descend to the specified depth and detect the water quality. Furthermore, by slowly pushing away the aquatic plants, it will not cause agitation and can prevent organic and inorganic impurities from floating at the bottom of the pool, thus affecting the detection results of the water quality sensor.

[0021] Second, the present invention is equipped with an air pipe. When the disc rises inside the cylinder, the spring is compressed, and the sealing disc blocks the gap between the disc and the first rod, greatly reducing gas leakage. The gas is concentrated and sprayed out from the air pipe and blown toward the water quality sensor to clean the water stains attached to the surface and prevent dirt from sticking and affecting the next test.

[0033] To better understand the purpose, technical solution, and advantages of this application, the application is described and illustrated below in conjunction with the accompanying drawings and embodiments.

[0034] Please see Figures 1 to 10 This invention provides a technical solution: an automatic water quality monitoring device for aquaculture, comprising:

[0035] A cylindrical tube 4, with a floating plate 3 and a support plate 2 fixedly installed at both ends of the cylindrical tube 4, respectively;

[0036] A drive assembly, mounted on the support plate 2, includes a first circular rod 6 for limiting the vertical movement of the detection assembly;

[0037] The detection component includes several water quality sensors 25 to collect water quality parameters;

[0038] The actuating mechanism is located below the moving path of the detection component and includes a spreading component sleeved outside the first round rod 6; when the detection component is driven downward by the driving component, the spreading component is squeezed by the detection component and generates radial expansion motion.

[0039] The spreading assembly includes a floating block 18 and a support plate 21. Several first connecting rods 19 are evenly rotatably installed on the outer wall of the floating block 18. Several second connecting rods 20 are evenly rotatably installed on the upper surface of the support plate 21. The second connecting rods 20 and the first connecting rods 19 are rotatably connected. A buckle 2201 is installed on the outer wall of the second connecting rod 20. An elastic rope 22 is sleeved inside the buckle 2201.

[0040] Furthermore, such as Figures 1 to 3 As shown, a controller 7 and a battery 8 are installed on the upper surface of the support plate 2, a number of support rods 5 are evenly installed on the upper surface of the floating plate 3, a solar panel 1 is installed on the upper surface of the support rods 5, and an opening 9 is opened on the lower surface of the floating plate 3.

[0041] Solar panel 1 supplies power to battery 8, and controller 7 sets relevant parameters.

[0042] Furthermore, such as Figure 4 As shown, the drive assembly includes a servo motor 10, which is fixedly mounted on the support plate 2. A second round rod 11 is fixedly mounted on the output shaft of the servo motor 10. Retaining rings 12 are symmetrically mounted on the outer wall of the second round rod 11. A support block 13 is rotatably mounted on the end of the second round rod 11 away from the servo motor 10. The lower end face of the support block 13 is fixedly mounted on the support plate 2. Pull ropes 14 are symmetrically wound on the outer wall of the second round rod 11.

[0043] When the servo motor 10 is working, it drives the second round rod 11 to rotate, and the second round rod 11 drives the pull rope 14 to wind up or unwind.

[0044] Furthermore, such as Figure 5 As shown, the detection component includes a disc 15, a gravity block 17 is fixedly installed on the lower end face of the disc 15, a water quality sensor 25 is installed on the lower end face of the disc 15, and air tubes 16 are symmetrically installed on both sides of the water quality sensor 25. The air tubes 16 penetrate the disc 15, and the disc 15 is installed at the end of the pull rope 14.

[0045] In this embodiment, the water quality sensor 25 includes various types, such as dissolved oxygen sensor, pH sensor, temperature sensor, turbidity sensor, etc. When the rope 14 is unwound, the gravity block 17 descends, driving the disc 15 to descend. The disc 15 drives the water quality sensor 25 to descend to different depths, and performs water quality detection on the water at different depths.

[0046] Furthermore, such as Figure 10 As shown, a number of ball bearings 26 are installed at the contact point between the gravity block 17 and the first round rod 6;

[0047] The ball bearing 26 can reduce the friction between the gravity block 17 and the first round rod 6.

[0048] Furthermore, such as Figure 7 and Figure 9 As shown, a sealing disc 24 is slidably mounted on the outer wall of the first round rod 6, and a spring 23 is mounted on the upper end face of the sealing disc 24. The side of the spring 23 away from the sealing disc 24 is mounted on the support plate 2.

[0049] As the disc 15 rises inside the cylinder 4, the spring 23 is compressed, and the sealing disc 24 blocks the gap between the disc 15 and the first rod 6, greatly reducing gas leakage. This causes the gas to be concentrated and ejected from the gas pipe 16, blowing towards the water quality sensor 25 and cleaning the water stains adhering to its surface.

[0050] As the disc 15 descends inside the cylinder 4, the spring 23 automatically extends, and the thrust generated by the extension of the spring 23 acts on the disc 15, helping it to descend smoothly.

[0051] Furthermore, such as Figure 6 As shown, the support plate 21 is fixedly installed on the outer wall of the first round rod 6, and the floating block 18 is slidably installed on the outer wall of the first round rod 6;

[0052] When the floating block 18 is squeezed by the gravity block 17, it will squeeze the first connecting rod 19. The first connecting rod 19 will squeeze the second connecting rod 20. Since the other end of the second connecting rod 20 is rotatably mounted on the support plate 21, the connection between the first connecting rod 19 and the second connecting rod 20 will cause the buckle 2201 to expand outward. The buckle 2201 will cause the elastic rope 22 to be pushed outward. At this time, the elastic rope 22 will push the outer water plants to move.

[0053] Furthermore, such as Figure 4 As shown, the upper end of the first round rod 6 penetrates the support plate 2;

[0054] The support plate 2 can slide on the first round rod 6 to cope with small changes in water level.

[0055] Working principle: Step 1: After the fishpond is prepared, water is poured in, and then the first round rod 6 is inserted into the bottom of the fishpond. At this time, the first round rod 6 is fixed, and the support plate 21 is in contact with the bottom of the pond. The floating plate 3 floats on the water surface, the solar panel 1 charges the battery 8, and the controller 7 sets the detection interval according to actual needs to prepare for subsequent water quality testing.

[0056] Step 2: As the breeding time progresses, when the preset detection time is reached, the servo motor 10 starts and begins to rotate, driving the second round rod 11 connected to it to rotate synchronously. During the rotation, the second round rod 11 unwinds the pull rope 14 wrapped around the outside. The gravity block 17, with its own gravity, drives the water quality sensor 25 to gradually descend through the disc 15. When it descends to a specific height, the water quality sensor 25 begins to accurately detect the water quality parameters of the corresponding water layer and obtain the real-time data of the water layer.

[0057] Step 3: When bottom testing is required, the gravity block 17, during its descent, compresses the floating block 18. The floating block 18 then slides downwards on the first round rod 6, compressing the first connecting rod 19. The compressed first connecting rod 19, using its connection to the floating block 18 as a pivot, rotates outwards. Simultaneously, the rotation of the first connecting rod 19 drives the second connecting rod 20, which also rotates outwards using its connection to the support plate 21 as a pivot. During this process, the second connecting rod 20 pulls the elastic rope 22 outwards via the buckle 2201. As the floating block 18 continues to descend, the elastic rope 22 gradually opens fully, slowly and steadily pushing away the outer aquatic plants. Simultaneously, as the aquatic plants are pushed away from the first round rod 6, the gravity block 17, through the disc 15, moves the water quality sensor 25 to its lowest position, close to the bottom of the pool. Since the aquatic plants have been properly cleared, the water quality sensor 25 can now accurately test the water quality at the bottom of the pool. The entire process of cleaning aquatic plants is carried out by pushing slowly, which avoids violent agitation of the water and effectively prevents organic and inorganic impurities at the bottom of the pool from floating up due to agitation, thereby avoiding interference with the detection results of the water quality sensor 25.

[0058] Step 4: After all testing tasks are completed, the servo motor 10 rotates in the reverse direction, driving the second rod 11 to rotate synchronously in reverse. During the reverse rotation, the second rod 11 winds up the pull rope 14, which then pulls the disc 15 and the gravity block 17 upwards. As the disc 15 rises inside the cylinder 4, the spring 23 is compressed and contracts. At the same time, the sealing disc 24 quickly takes effect, tightly sealing the gap between the disc 15 and the first rod 6, greatly reducing gas leakage. After this sealing treatment, the gas is concentrated and ejected from the gas pipe 16. The airflow blows directly onto the water quality sensor 25, cleaning the water stains adhering to the surface of the water quality sensor 25, promoting its rapid drying, effectively preventing stains from sticking together, and ensuring that the water quality sensor 25 can work normally and obtain accurate data in the next test.
