Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture equipment, and in particular relates to an aquaculture water quality monitoring system. Background Art

[0002] Aquaculture water quality monitoring involves using technical means to conduct real-time or regular testing of aquaculture water environmental parameters to ensure the healthy growth of aquatic organisms. Its core objective is to monitor key indicators that affect the survival of fish, shrimp, crabs, and other species, including water temperature, dissolved oxygen, pH, ammonia nitrogen, nitrite, and transparency. For example, insufficient dissolved oxygen can cause fish to suffocate, while excessive ammonia nitrogen can cause poisoning. Monitoring methods include manual sampling and testing (laboratory analysis) and intelligent online monitoring (sensors transmitting data in real time). Data analysis can promptly detect water quality anomalies, guide water diversion, oxygenation, or water changes, prevent disease outbreaks, and improve aquaculture efficiency and ecological sustainability.

[0003] A Chinese patent application with publication number CN216013347U discloses an aquaculture water quality monitoring system, comprising: a support rod; a first support frame, the first support frame is fixedly mounted on the surface of the support rod; a camera, the camera is fixedly mounted on the bottom of the first support frame; a drive assembly, the drive assembly is fixedly mounted on one end of the top of the first support frame; and a connecting rope, the connecting rope is arranged at one end of the drive assembly. The system solves the problem that in the existing water quality detection system, during use, the camera only detects the surrounding environment of the aquaculture pond and the normal activities of aquatic products in the water, but cannot detect slight changes in the color of the water body caused by changes in the dominant populations of different plankton in the water body, resulting in certain limitations in use.

[0004] However, the above-mentioned device still has the following problems during implementation: the monitoring relies on a motor-driven cable to release the sensor, which can only detect a single fixed position and is difficult to cover the vast different water layers and points in the aquaculture area. At the same time, the booster and fluid replenishment equipment are fixedly installed and cannot be flexibly moved to the hypoxic area for precise oxygen replenishment based on real-time monitoring data, resulting in low resource allocation efficiency and the inability to solve the local hypoxia problem in a timely manner. This "fixed-point" monitoring and supply mode is difficult to meet the needs of large-scale and dynamic aquaculture.

[0005] To this end, we provide an aquaculture water quality monitoring system to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an aquaculture water quality monitoring system. Through the cooperation of an adjusting component, a moving component and a supplementary component, the present invention solves the problem that the existing water quality monitoring system needs to use a motor to release the cable when monitoring water quality, so that the sensor can penetrate into the water layer for detection, and can only detect a single position.

[0011] The present invention is further configured such that the supplementary component also includes an air pipe connected to one side of the oxygen pump, a sealing shell sleeved on the surface of the air pipe, and an air hole opened on one side of the rotating shaft.

[0012] The present invention is further configured such that the other end of the gas delivery pipe is communicated with the sealing shell, and one side of the sealing shell is fixedly connected to the inner wall of the movable shell.

[0013] The present invention is further configured such that the supplementary component also includes a delivery pipe connected to one side of the delivery pump, a first bevel gear installed on one side of the rotating shaft, a second bevel gear meshed with one side of the first bevel gear, a rotating tube installed at the axis of the second bevel gear, and a nozzle connected to the bottom of the rotating tube.

[0014] The present invention is further configured such that a fixed shell is sleeved on the surface of the rotating tube, an infusion hole is opened on the surface of the rotating tube, and the other end of the delivery tube is connected to the fixed shell.

[0015] The present invention is further configured such that a shielding shell is movably connected to the surface of the rotating tube via a bearing, and one side of the shielding shell is fixedly connected to the movable shell.

It solves the limitation of traditional fixed-depth monitoring that cannot cover the changes in water quality stratification, and improves the dynamic monitoring capability of multiple water layers. The integrated design of the metal hose and the air jet pipe integrates the oxygen delivery and sensor monitoring functions. When an oxygen-deficient area is detected, the oxygen enrichment function can be synchronously activated to realize the instant linkage of monitoring and adjustment.

[0020] 2.

The auxiliary wheels and the support seat reduce friction and improve the movement stability, so that the sensor can cover multiple points in the entire aquaculture pond, solving the problem of insufficient coverage of traditional fixed-point monitoring. After receiving the sensor data, the central controller can link the servo motor to adjust the moving path and cooperate with the drive motor to control the sinking depth to realize automatic cruise monitoring of large areas of water. This structural design enables the system to flexibly adapt to aquaculture ponds of different sizes and meet the needs of dynamic and global water quality management.

[0032] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1

[0034] See also Figures 1-8 The present invention is an aquaculture water quality monitoring system, comprising a mobile shell 1, a counterweight 2 is provided at the bottom of the mobile shell 1, and a temperature sensor 3 and a water quality sensor 4 are fixedly connected to the bottom of the counterweight 2 respectively; an adjusting component is provided inside the mobile shell 1, the adjusting component comprises a rotating shaft 5 movably connected to the inside of the mobile shell 1, a winding roller 6 installed on the surface of the rotating shaft 5, and a metal hose 7 connected to one side of the rotating shaft 5, and the monitoring depth of the temperature sensor 3 and the water quality sensor 4 is adjusted by the adjusting component; a mobile component is provided on one side of the mobile shell 1, the mobile component comprises a bracket 8 provided on one side of the mobile shell 1, a line roller 9 movably connected to the inside of the bracket 8, and a steel rope 10 sleeved on the surface of the line roller 9, and the monitoring range of the temperature sensor 3 and the water quality sensor 4 is adjusted by the mobile component; a supplementary component is provided inside the mobile shell 1, the supplementary component comprises an oxygenation pump 11 installed on the top of the mobile shell 1, a water tank 12 installed inside the mobile shell 1, and a delivery pump 13 connected to one side of the water tank 12, and the water body is actively oxygenated and replenished with fluid through the supplementary component.

[0035] Specifically: the counterweight block 2 assists the mobile shell 1 in sinking through the action of gravity, ensuring that the temperature sensor 3 and the water quality sensor 4 reach the set water depth quickly and accurately during the release process, and at the same time enhances the stability of the overall structure in the water flow to prevent the sensor from being offset due to the impact of the water flow. The temperature sensor 3 and the water quality sensor 4 collect key indicators such as water temperature, dissolved oxygen, and pH value in real time, and move to different points with the mobile shell 1 through the metal hose 7 to achieve dynamic multi-point monitoring of the entire aquaculture pond. The rotating shaft 5 and the winding roller 6 drive the metal hose 7 to release or recycle, control the sinking depth of the sensor, and accurately adjust the speed of the winding roller 6 through the drive motor 31 to adapt to different water depth requirements, avoiding the sensor being unable to adapt to dynamic water quality stratification changes due to fixed depth.

[0036] Example 2

[0037] See also Figures 1-8 On the basis of Example 1, the moving component also includes an auxiliary roller 14 sleeved inside the steel cable 10, a support seat 15 installed on the surface of the auxiliary roller 14, a fixed block 16 installed on the surface of the steel cable 10, one side of the fixed block 16 is fixedly connected to the moving shell 1, and an auxiliary wheel 17 is slidably connected to the surface of the steel cable 10, and one side of the auxiliary wheel 17 is movably connected to the moving shell 1. The supplementary component also includes an air pipe 18 connected to one side of the oxygen pump 11, a sealing shell 19 sleeved on the surface of the air pipe 18, an air hole 20 opened on one side of the rotating shaft 5, the other end of the air pipe 18 is connected to the sealing shell 19, and one side of the sealing shell 19 is fixedly connected to the inner wall of the moving shell 1. The supplementary component also includes a delivery pipe 21 connected to one side of the delivery pump 13, a first bevel gear 22 installed on one side of the rotating shaft 5, a second bevel gear 23 meshing with one side of the first bevel gear 22, a rotating tube 24 installed at the axis center of the second bevel gear 23, and a nozzle 25 connected to the bottom of the rotating tube 24.

[0038] Specifically: the bracket 8 and the line roller 9 are fixed at both ends of the breeding pond. The line roller 9 drives the steel cable 10 to move in a circular motion through the servo motor 30, driving the mobile shell 1 to move laterally to cover the entire breeding area. The steel cable 10 cooperates with the fixed block 16 to ensure that the mobile shell 1 moves smoothly along the preset trajectory. The auxiliary wheel 17 can reduce the friction between the steel cable 10 and the mobile shell 1, extend the life of the equipment, and ensure smooth movement. The fixed block 16 transmits the tension of the steel cable 10 to the mobile shell 1, driving it to move horizontally. The oxygen pump 11 and the air pipe 18 inject compressed air into the metal hose 7 through the sealing shell 19 and the air hole 20 of the rotating shaft 5, and finally releases oxygen to the target water layer through the jet pipe 29, accurately locating the hypoxic area and realizing oxygen supplementation on demand.

[0039] Example 3

[0040] See also Figures 1-8On the basis of Examples 1 and 2, a fixed shell 26 is provided on the surface of the rotating tube 24, an infusion hole 27 is opened on the surface of the rotating tube 24, the other end of the delivery tube 21 is connected to the fixed shell 26, and a shielding shell 28 is movably connected to the surface of the rotating tube 24 through a bearing. One side of the shielding shell 28 is fixedly connected to the movable shell 1, the other end of the metal hose 7 is fixedly connected to the counterweight 2, and one side of the metal hose 7 is connected to the jet pipe 29. A servo motor 30 is fixedly connected to one side of the bracket 8, and the output end of the servo motor 30 is fixedly connected to the line roller 9. A drive motor 31 is fixedly connected to the inside of the movable shell 1, and the output end of the drive motor 31 is fixedly connected to the rotating shaft 5. A central controller 32 is fixedly connected to one side of the water tank 12, and the input end of the central controller 32 is unidirectionally electrically connected to the output end of the temperature sensor 3 and the water quality sensor 4, and the output end of the central controller 32 is unidirectionally electrically connected to the input end of the oxygen pump 11, the delivery pump 13, the servo motor 30 and the drive motor 31.

[0041] Specifically: the central controller 32 is bidirectionally electrically connected with a wireless transmission module, which can upload the detection information to the staff's handheld terminal in real time. The water tank 12 and the delivery pump 13. The water tank 12 stores pH regulating liquid, and the liquid is pressurized and delivered to the rotating tube 24 by the delivery pump 13. It is sprayed out through the nozzle 25, and alkaline substances can be replenished in real time according to the detection data of the water quality sensor 4, quickly neutralizing the acidic water body and stabilizing the pH value. The first bevel gear 22 and the second bevel gear 23 are engaged with the gears to convert the horizontal rotation of the rotating shaft 5 into the vertical rotation of the rotating tube 24, ensuring that the nozzle 25 always sprays the pH supplement liquid downward during the movement. The jet pipe 29 is integrated at the end of the metal hose 7 and is connected to the air pipe 18 to pump the oxygen pump. The air delivered by 11 is released into the water body in the form of microbubbles, which increases the oxygen dissolution efficiency, quickly increases the local dissolved oxygen content, and alleviates the problem of fish hypoxia. The servo motor 30 and the drive motor 31 accurately control the rotation speed of the line roller 9 to achieve adjustable lateral movement speed of the mobile shell 1 to meet the requirements of different breeding pond areas. The drive motor 31 adjusts the rotation speed of the rotating shaft 5 to control the sinking depth of the sensor to meet the requirements of layered monitoring. The central controller 32 integrates data acquisition and equipment control functions, receives real-time data from the sensor, automatically analyzes water quality abnormalities, and triggers the oxygen pump 11, delivery pump 13, servo motor 30 and drive motor 31 to respond in a coordinated manner, realizing full automation of monitoring, decision-making and execution, reducing manual intervention and improving efficiency.

[0042] The working principle of the present invention is as follows: before water quality monitoring, the staff can install the bracket 8 and the support seat 15 at both ends of the aquaculture pond, and set up the steel cable 10 on the top of the water surface of the aquaculture pond. When the water quality needs to be tested, the staff can start the servo motor 30. The servo motor 30 cooperates with the line roller 9 to drive the steel cable 10 to rotate in a circular manner. When the steel cable 10 moves, it cooperates with the fixed block 16 to drive the movable shell 1 to move. The movable shell 1 cooperates with the metal hose 7 to drive the temperature sensor 3 and the water quality sensor 4 to move. After moving to the specified position, the drive motor 31 can be started. The drive motor 31 cooperates with the rotating shaft 5 to drive the winding roller 6 to rotate. The winding roller 6 releases the metal hose 7, and sinks into the water layer under the action of the counterweight block 2. The water quality sensor 4 is used to detect the pH value, dissolved oxygen (DO), conductivity (EC), turbidity, chemical oxygen demand (COD), ammonia nitrogen, temperature and other indicators of water quality in different water layers.

[0043] Afterwards, the servo motor 30 can be controlled to continue to drive the steel rope 10 to move, and the monitoring range of the temperature sensor 3 and the water quality sensor 4 can be adjusted to cover the entire aquaculture sugar and meet the large-scale aquaculture detection needs.

[0044] When the water quality sensor 4 detects that the dissolved oxygen content of the water at the current position is low, the oxygenation pump 11 can be started. The oxygenation pump 11 inputs gas into the gas pipe 18, enters the gas delivery hole 20 through the sealing shell 19, and enters the metal hose 7 through the rotating shaft 5. The oxygen is injected into the water layer through the metal hose 7, and the gas is ejected through the jet pipe 29 to increase the oxygen capacity at the current position. The oxygen can be delivered accurately, solving the problem of slow oxygenation of the booster at a fixed position. At the same time, the delivery pump 13 can also be started. The delivery pump 13 draws the pH supplement liquid in the water tank 12 into the delivery pipe 21, and ejects the pH supplement liquid through the infusion hole 27, the rotating tube 24 and the nozzle 25. The pH supplement liquid is mainly used to adjust the pH of the water body, maintain a suitable breeding environment, realize simultaneous detection and adjustment, and improve the breeding effect.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
