Description

Technical Field

[0001] The invention relates to the technical field of fishery water quality detection, in particular to an automatic monitoring device for fishery aquaculture water quality. Background Art

[0002] Fishery farming, also known as aquaculture, covers a variety of models such as extensive farming, intensive farming and high-density intensive farming. In the current context of increasingly scarce resources, intensive farming has been widely promoted due to its advantages such as high efficiency. Intensive farming generally involves artificially excavating fish ponds and raising fish in them to meet market needs.

[0003] Under the intensive farming model, due to the high breeding density, fish metabolic products, residual feed, etc. are easy to accumulate, and water quality changes are faster and more complex, which has a significant impact on fish growth, health and breeding benefits. Therefore, it is necessary to conduct regular water quality testing, discover water quality problems in time and take corresponding measures to adjust and improve them.

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

[0005] The purpose of the present invention is to provide an automatic monitoring device for water quality in fishery aquaculture, which solves the problem that the existing device is easily affected by aquatic plants and causes inaccurate detection.

[0006] To achieve the above object, the present invention provides the following technical solution: an automatic monitoring device for fishery water quality, comprising: A cylinder, with a floating plate and a supporting plate fixedly mounted on both ends of the cylinder; A driving assembly, disposed on the supporting plate, comprising a first round rod, used to limit the vertical movement of the detection assembly; Detection components, including several water quality sensors, to collect water quality parameters; The toggle mechanism is arranged below the moving path of the detection component, and includes an expansion component sleeved outside the first round rod; when the detection component is driven by the driving component to move downward, the expansion component is squeezed by the detection component to generate radial expansion movement; The expansion assembly includes a floating block and a support plate. The outer wall of the floating block is evenly rotatably mounted with a plurality of first connecting rods. The upper end surface of the support plate is evenly rotatably mounted with a plurality of second connecting rods. The second connecting rods are rotatably connected to the first connecting rods. A buckle is mounted on the outer wall of the second connecting rod, and an elastic rope is sleeved inside the buckle.

[0007] Preferably, a controller and a battery are installed on the upper end surface of the support plate, a plurality of support rods are evenly installed on the upper end surface of the floating plate, a solar panel is installed on the upper end surface of the support rods, and an opening is formed on the lower end surface of the floating plate.

[0008] Preferably, the driving assembly includes a servo motor, the servo motor is fixedly mounted on a support plate, a second round rod is fixedly mounted on the output shaft of the servo motor, a retaining ring is symmetrically mounted on the outer wall of the second round rod, a support block is rotatably mounted on one end of the second round rod away from the servo motor, the lower end surface of the support block is fixedly mounted on the support plate, and a pull rope is symmetrically wound on the outer wall of the second round rod.

[0009] Preferably, the detection component includes a disc, a gravity block is fixedly mounted on the lower end surface of the disc, the water quality sensor is mounted on the lower end surface of the disc, air pipes are symmetrically mounted on both sides of the water quality sensor, the air pipes pass through the disc, and the disc is mounted at the end of the pull rope.

[0012] Preferably, the support plate is fixedly mounted on the outer wall of the first round rod.

[0013] Preferably, the floating block is slidably mounted on the outer wall of the first round rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a toggle mechanism. When the gravity block squeezes the floating block, the floating block moves downward on the first round rod and squeezes the first connecting rod. The first connecting rod squeezes the second connecting rod. At this time, the first connecting rod rotates outward with the connection between the first connecting rod and the floating block as the axis, and the second connecting rod rotates outward with the connection between the second connecting rod and the support plate as the axis. At the same time, the second connecting rod drives the elastic rope to move outward through the buckle, and the elastic rope gradually becomes larger to push away the water plants on the outside. At this time, the water quality sensor can descend to the specified depth and detect the water quality, and push away the water plants by slowly pushing, which will not cause stirring, and can prevent impurities such as organic and inorganic substances on the bottom of the pool from floating and affecting the detection results of the water quality sensor.

[0015] 2. The present invention is provided with an air pipe. When the disc rises in the cylinder, the spring is compressed, and the sealing disc blocks the gap between the disc and the first round rod, greatly reducing gas leakage, so that the gas is concentratedly ejected from the air pipe and blown toward the water quality sensor to clean water stains attached to the surface and prevent dirt from sticking and affecting the next detection.

Specific Embodiments

[0018] To more clearly understand the purpose, technical solution and advantages of the present application, the present application will be described and illustrated below with reference to the accompanying drawings and embodiments.

[0019] Please refer to Figures 1 to 10 , the present invention provides a technical solution: an automatic water quality monitoring device for fishery aquaculture, comprising: a cylinder 4, with a floating plate 3 and a support plate 2 fixedly installed at both ends of the cylinder 4 respectively; a driving assembly, arranged on the support plate 2, including a first round rod 6 for restricting the vertical movement of the detection assembly; a detection assembly, including a plurality of water quality sensors 25 for collecting water quality parameters; The toggle mechanism is arranged below the moving path of the detection component, and includes an expansion component sleeved outside the first round rod 6; when the detection component is driven by the driving component to move downward, the expansion component is squeezed by the detection component to produce radial expansion movement; The expansion assembly includes a floating block 18 and a support plate 21. The outer wall of the floating block 18 is evenly rotatably mounted with a plurality of first connecting rods 19. The upper end surface of the support plate 21 is evenly rotatably mounted with a plurality of second connecting rods 20. The second connecting rods 20 are rotatably connected to the first connecting rods 19. A buckle 2201 is mounted on the outer wall of the second connecting rod 20. An elastic rope 22 is sleeved inside the buckle 2201.

[0020] Further, such as Figures 1 to 3 As shown, a controller 7 and a battery 8 are installed on the upper end surface of the support plate 2, a plurality of support rods 5 are evenly installed on the upper end surface of the floating plate 3, a solar panel 1 is installed on the upper end surface of the support rods 5, and an opening 9 is opened on the lower end surface of the floating plate 3; The solar panel 1 supplies power to the battery 8, and the controller 7 sets relevant parameters.

[0021] Further, such as Figure 4 As shown, the driving assembly includes a servo motor 10, which is fixedly mounted on a support plate 2, a second round rod 11 is fixedly mounted on the output shaft of the servo motor 10, a retaining ring 12 is symmetrically mounted on the outer wall of the second round rod 11, a support block 13 is rotatably mounted on one end of the second round rod 11 away from the servo motor 10, the lower end surface of the support block 13 is fixedly mounted on the support plate 2, and a pull rope 14 is symmetrically wound on the outer wall of the second round rod 11; 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 reel in or unreel.

[0022] Further, such as Figure 5 As shown, the detection assembly includes a disc 15, a gravity block 17 is fixedly mounted on the lower end surface of the disc 15, the water quality sensor 25 is mounted on the lower end surface of the disc 15, air pipes 16 are symmetrically mounted on both sides of the water quality sensor 25, the air pipes 16 penetrate the disc 15, and the disc 15 is mounted at the end of the pull rope 14; 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 pull rope 14 is unwound, the gravity block 17 descends, driving the disc 15 to descend, and the disc 15 drives the water quality sensor 25 to descend to different depths to perform water quality detection on water at different depths.

[0023] Further, such as Figure 10 As shown, a plurality of balls 26 are installed at the abutment between the gravity block 17 and the first round rod 6; The ball 26 can reduce the frictional force between the gravity block 17 and the first round rod 6.

[0024] Furthermore, as Figure 7 and Figure 9 shown, a sealing disc 24 is slidably mounted on the outer wall of the first round rod 6, a spring 23 is mounted on the upper end face of the sealing disc 24, and one side of the spring 23 away from the sealing disc 24 is mounted on the support plate 2; When the disc 15 rises in the cylinder 4, the spring 23 is compressed, and the sealing disc 24 blocks the gap between the disc 15 and the first round rod 6, greatly reducing gas leakage, so that the gas is concentrated and ejected from the air pipe 16 and blown towards the water quality sensor 25 to clean the water stains attached to the surface.

[0025] When the disc 15 descends in the cylinder 4, the spring 23 will automatically extend, and the thrust generated by the extension of the spring 23 acts on the disc 15 to assist its smooth descent.

[0026] Furthermore, as Figure 6 shown, the support disc 21 is fixedly mounted on the outer wall of the first round rod 6, and the floating block 18 is slidably mounted on the outer wall of the first round rod 6; When the floating block 18 is squeezed by the gravity block 17, it will squeeze the first connecting rod 19, and the first connecting rod 19 squeezes the second connecting rod 20. Since the other end of the second connecting rod 20 is rotatably mounted on the support disc 21, the connection between the first connecting rod 19 and the second connecting rod 20 will drive the buckle 2201 to expand outwards, and the buckle 2201 drives the elastic cord 22 to expand outwards. At this time, the elastic cord 22 will push the outer aquatic plants to move.

[0027] Furthermore, as Figure 4 shown, the upper end of the first round rod 6 penetrates through the support plate 2; The support plate 2 can slide on the first round rod 6 to cope with small changes in water level.

[0028] Working principle: The first step: After the fishing pond is tidied up and filled with water, then insert the first round rod 6 into the bottom of the fishing pond. At this time, the first round rod 6 is fixed, and at the same time, the support disc 21 abuts against the bottom of the pond. The floating plate 3 floats on the water surface, the solar panel 1 charges the battery 8, and sets the detection interval time according to actual needs through the controller 7 to prepare for the subsequent water quality detection work.

[0029] Step 2: As the breeding time progresses, when the preset detection moment is reached, the servo motor 10 starts to rotate, driving the second round rod 11 connected thereto to rotate synchronously. During the rotation, the second round rod 11 unwinds and winds the pulling rope 14 wound around the outside. The gravity block 17, by virtue of 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 starts to accurately detect the water quality parameters of the corresponding water layer and obtain the real-time data of this water layer.

[0030] Step 3: When it is necessary to detect the bottom of the pool, the gravity block 17 will squeeze the floating block 18 during the descent. The floating block 18 then slides downward on the first round rod 6 and squeezes the first connecting rod 19. The squeezed first connecting rod 19 rotates outward with its connection point with the floating block 18 as the rotation axis. At the same time, the rotation of the first connecting rod 19 drives the second connecting rod 20, and the second connecting rod 20 also rotates outward with its connection point with the support disc 21 as the rotation axis. During this process, the second connecting rod 20 pulls the elastic rope 22 to stretch outward through the buckle 2201. As the floating block 18 continues to descend, the elastic rope 22 gradually fully unfolds, and the waterweeds on the outside are gently pushed away in a slow and stable manner. While the waterweeds are pushed away from the first round rod 6, the gravity block 17 drives the water quality sensor 25 to move to the lowest position, close to the bottom of the pool, through the disc 15. Since the waterweeds have been properly cleared, the water quality sensor 25 can accurately detect the water quality at the bottom of the pool at this time. The entire process of clearing the waterweeds adopts a slow-pushing method, avoiding violent agitation of the water body, effectively preventing impurities such as organic and inorganic substances at the bottom of the pool from floating up due to agitation, and thus avoiding interference with the detection results of the water quality sensor 25.

[0031] Step 4: After all the detection tasks are completed, the servo motor 10 rotates in the reverse direction, driving the second round rod 11 to reverse synchronously. During the reverse rotation, the second round rod 11 winds up the pulling rope 14, and the pulling rope 14 immediately pulls the disc 15 and the gravity block 17 to rise upward. When the disc 15 rises in the cylinder 4, the spring 23 is compressed and contracts. At the same time, the sealing disc 24 quickly comes into play and tightly blocks the gap between the disc 15 and the first round rod 6, greatly reducing gas leakage. After this sealing treatment, the gas is concentrated and ejected from the air pipe 16, and the air flow directly blows on the water quality sensor 25, cleaning the water stains attached to the surface of the water quality sensor 25 and promoting its rapid drying, effectively preventing stain adhesion, and ensuring that the water quality sensor 25 can work normally and obtain accurate data during the next detection.
