Description

Technical Field

[0001] The invention relates to a water quality dynamic monitoring and medicine proportioning delivery technology, belonging to the technical field of fishery breeding. Background Art

[0002] As people's living standards continue to improve, the demand for aquatic products is increasing rapidly. Fishery aquaculture plays a key role in ensuring food security, increasing fishermen's income, optimizing people's dietary structure and ensuring national food security.

[0003] However, the current level of automation in my country's fishery farming industry is low. When there is a problem with the water quality in the fish pond, it is necessary to manually row a boat to take samples and test the water quality and to use extensive spraying of chemicals to improve the water quality. Too much chemical input can easily lead to eutrophication of the water body, further curbing the growth of aquatic products, while too little chemical input can fail to improve the water environment, and aquatic products still grow in a pathological environment. There are pain points in fishery farming such as untimely water quality monitoring, inaccurate drug addition, and low efficiency of manual drug administration, which lead to high risks in fishery farming.

[0004] In the prior art, attempts have been made to optimize the water quality environment by setting up an automatic dosing machine in order to improve the aquaculture environment. For example, the invention patent application with publication number CN107347751A discloses an automatic dosing machine for fish farming. The device pours the liquid medicine into the medicine box of the feeder, turns on the motor, and uses the pressure difference between the mixing box and the outside world to suck the liquid medicine and the water in the pond into the mixing box for mixing, and then uses a water pump to transport the mixed liquid medicine to the nozzle through the liquid outlet pipe to achieve automatic and uniform dosing. However, the shortcoming of this device is that it only solves the problem of replacing manual dosing, and it is impossible to adjust the amount of medicine added according to the actual water quality. Therefore, it cannot accurately improve the water quality, nor can it achieve dynamic adjustment according to the growth environment of aquatic products. It has low precision and limited automation, and there is still the problem of unreasonable dosing of medicine.

[0005] With the development of Internet of Things technology, the field of aquaculture has also begun to try to improve water quality through online monitoring and real-time regulation. For example, the invention patent application with publication number CN117837548A discloses a multi-node online monitoring and control device for water quality. The device collects data such as temperature, pH value, dissolved oxygen and free ammonia nitrogen of the water body through multiple water quality monitoring nodes, and controls the feeder to release the bottom-improving agent according to the monitoring results. Although this technology realizes dynamic agent regulation based on water quality monitoring results, there are still some obvious problems. First, in order to adapt to ponds of different shapes and sizes, a large number of water quality monitoring nodes need to be deployed, which is costly and complex to maintain. Secondly, the position of the feeder is fixed, and the water body of the pond is usually not flowing, which limits the accuracy of the monitoring data. In addition, the device can only roughly control the type and dosage of the agent according to the water quality data, and it is difficult to achieve accurate adjustment of the amount of agent released, resulting in unstable efficacy and failure to fully meet the needs of refined water quality management.

[0006] From the above analysis, it can be seen that the existing fishery breeding dosing devices and water quality monitoring and control devices cannot realize the intelligent proportioning and precise delivery of drugs based on the results of water quality monitoring. It is necessary to install many water quality monitoring nodes to collect data and deploy multiple feeders to deliver improved drugs, which is very costly. The hardware installation and deployment position is fixed, and the pond water has poor circulation, which is not conducive to real-time and accurate acquisition of fish pond water quality parameters and remote control. It is not possible to keep aquatic products in the most suitable growth environment at all times. Summary of the invention

[0007] Technical problem: In view of the above technical deficiencies, the present invention mainly proposes a device for dynamic water quality monitoring and drug proportioning for aquaculture, which can simultaneously realize the three core functions of dynamic water quality monitoring, intelligent drug proportioning, and precise drug delivery. The device for monitoring water quality and delivering drugs supports autonomous movement on water, and supports remote control by cloud supervision platform.

[0008] Objective: We are committed to proposing a monitorable, controllable and adjustable intelligent aquaculture solution, which uses the dynamic monitoring results of water quality as feedback to control the intelligent proportioning and precise delivery of the types and contents of drugs, so that aquatic products are always in the most suitable growth environment, helping fishery farming to achieve increased production and income.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A device for dynamic monitoring of water quality and proportioning of medicines for aquaculture, characterized in that it comprises a telescopic energy supply structure of a solar panel, and a medicine proportioning structure, a medicine delivery structure, a water quality detection structure and a bionic propulsion structure located below the solar panel; wherein the water quality monitoring structure is used to monitor water quality parameters in real time, including turbidity, dissolved oxygen, pH, ammonia nitrogen, nitrite and water surface conditions; the medicine proportioning structure is used to deliver the required liquid medicine, and is equipped with 5 medicine delivery ports on the top, and the proportion of the medicine is accurately controlled by controlling the six-way pipe through the integrated control module; the medicine delivery structure is used to store and deliver the required medicine, and The liquid medicine sprays out from the nozzle in the form of mist. The water pump controls the pressure to control the delivery speed, and the dosage of the liquid medicine is controlled by the solenoid valve. The cloud monitoring platform is used to remotely monitor the water quality and control the device used to improve the water quality. The solar panel telescopic energy supply structure uses solar energy to assist the device in power supply and enhance the endurance. The solar panel is installed above the fixed bracket to capture solar energy and replenish it to ten groups of lithium batteries, which are combined in parallel and series to store electrical energy. The intelligent charging controller connects the solar panel and the lithium battery to control the charging state and charge amount of the battery, and monitors and adjusts the deployment state of the solar panel. The bionic propulsion structure is used to propel and tug the machine, and makes a posture suitable for propulsion according to the water surface conditions to adjust its own balance. The dissolved oxygen injection device includes a three-way flange connected to the air inlet end of the tubular aerator on the left and right, and the third end is connected to the air injection device at the bottom of the deck. The four tubular aerator components are symmetrically distributed left and right, front and back, and a diaphragm aerator is installed at the center of the bottom. The diaphragm aerator is located at the center of the bottom of the device.

[0011] The water quality dynamic monitoring and drug proportioning delivery device of the present invention is characterized in that, in addition to monitoring the turbidity, dissolved oxygen, pH value, ammonia nitrogen and nitrite of the water body, it can also monitor parameters such as water surface fluctuations and water speed. The collected data is processed by the sensor information collection module to adjust the balance of the device and the speed of the boat to match the delivery speed and dosage of the drug, so as to adapt to ponds of different sizes and shapes. The intelligent proportioning delivery device includes a drug storage container, a metering device and a delivery mechanism, and the delivery mechanism can accurately deliver the drug according to the proportioning result. The data collected by the sensor is used as feedback to control the electromagnetic integrated valve to extract an appropriate amount of drug from the drug liquid warehouse to the drug liquid mixing warehouse. After the drug is fully stirred in the mixing warehouse, the delivery position and dosage of the drug are controlled by the liquid pumping booster pump and the two-way valve. The drug liquid warehouse is symmetrically installed on the auxiliary plate in the front and back, and the auxiliary plate is provided with a hollow structure of the outline of six drug liquid warehouses.

[0012] The motor drives the power rocker to perform circular motion, and the power rocker cooperates with the machine bar slot to realize the rocker movement, thereby driving the floating plate adjustment module to complete the balance adjustment. The floating plate adjustment module consists of an air cushion capsule, a bionic propulsion structure and a balance air cushion module. The bionic propulsion structure includes a twin propeller, a main propeller and a reversing hydrofoil. The main propeller provides power propulsion, and the reversing hydrofoil assists the twin propellers to achieve the steering function of the device by adjusting the rotation direction and speed difference. The bottom imitates the double-sided balancing structure of the ship. By setting symmetrical buoyancy devices on both sides of the device to maintain the stability of the device, the main propeller provides forward propulsion power, cooperates with the twin propellers and the tail reversing hydrofoil, and adjusts the propeller speed through the differential principle to achieve flexible steering of the device.

[0013] The water quality dynamic detection and liquid medicine proportioning device will collect data such as water turbidity, dissolved oxygen, pH value, ammonia nitrogen, nitrite, and the content of medicine in the liquid medicine tank and mixing tank, and transmit it to the cloud supervision platform through the Lora Internet of Things. The cloud supervision platform can monitor the water quality of the fish pond and the liquid medicine in the device in real time, and support remote control devices to perform precise delivery of medicines.

[0014] The intelligent proportioning device for medicine also includes a mixing unit for uniformly mixing the medicine with water. The device controls the electromagnetic integrated valve based on sensor feedback to extract the appropriate amount of medicine on demand. The medicine liquid warehouse is made of different materials and is suitable for storing medicine liquid under different conditions. The negative pressure pump is connected to the six-way pipe to accelerate the flow of medicine liquid to the mixing warehouse by reducing the pressure in the pipeline. The fan blades in the mixing warehouse are driven by a high-speed motor to ensure uniform mixing of the medicine liquid. The fan is made of ceramic material and the pipeline is made of resistant plastic. The mixing warehouse is connected to the double-headed valve through a soft plastic pipeline. The two-way valve is closely matched with the liquid pumping booster pump. The liquid outlet pipe connects the nozzle and the booster pump to achieve high-pressure delivery of the medicine liquid. The two-way valve is a single-end closable type, and the liquid pumping booster pump is a dual-port design connected to the resistant pipeline. The medicine liquid mixing warehouse is installed in the middle of the alloy partition, and the medicine liquid warehouse is placed on both sides. The booster pump is installed on the front and back sides of the partition, and the four two-way valves are symmetrically distributed on both sides of the medicine liquid warehouse.

[0015] The liquid medicine mixing chamber is installed in the middle of the alloy partition, and the liquid medicine chambers extending from the top are placed on both sides. The liquid pumping booster pump is located on the front and rear sides of the alloy partition, and the four two-way valves are symmetrically distributed on the left and right sides of the liquid medicine chamber.

[0016] The floating plate adjustment module is symmetrically installed on the left and right sides of the device. The motors are located in the first and third quadrants of the splint, directly connected to the power rocker and interference fit. The battery is installed inside the deck to provide power for the motor. The water quality dynamic detection device is installed in the center of the front of the device and fixed to the splint by welding. The bottom detection module is deep in the water, and the water quality detection structure is connected to the battery.

[0017] The water quality monitoring structure is used to collect data such as water surface fluctuations and water speed, and automatically adjust the posture and direction of the device during movement to ensure its stability and balance.

[0018] The balanced air cushion module can adjust the volume and angle of sinking into the water to change the inclination of the device and adapt to different water surface environments.

[0019] The cloud monitoring platform includes a user interface for users to remotely monitor water quality conditions and control devices that improve water quality.

[0020] The dissolved oxygen injection device includes a three-way flange, which is connected to the air inlet end of the tubular aerator on the left and right, and the third end is connected to the air injection device at the bottom of the deck. The four tubular aerator components are symmetrically distributed on the left and right front and back of the device, and a diaphragm aerator is installed in the center of the bottom. When the device moves on the water surface, it cooperates with various structures through the air pump to inject dissolved oxygen into the water.

[0021] In summary, the present invention has a simple structure, is easy to operate, can achieve accurate delivery of liquid medicine, and effectively detects turbidity, dissolved oxygen, pH value, ammonia nitrogen, nitrite and water surface conditions in aquaculture ponds. The device can improve water quality, improve aquaculture quality, and reduce aquaculture costs.

[0022] The beneficial effects of the present invention are:

[0023] (1) The device supports autonomous movement on water, and can realize fixed-point and multi-region water quality sampling and monitoring. It also supports mobile drug delivery, avoiding inaccurate water quality monitoring and unreasonable drug delivery caused by stagnant fish pond water, ensuring that the drug is fully integrated with the water body to maximize the efficacy.

[0024] (2) Dynamic monitoring of water quality in the growth environment of aquatic products is achieved. Based on the path planned by the user, the device can perform fixed-point sampling in different waters, eliminating the need for multiple monitoring nodes and reducing hardware costs.

[0025] (3) Based on the water quality monitoring results, the required chemicals are intelligently proportioned to avoid proportioning errors caused by manual operation, improve breeding efficiency, and lower the threshold for breeding.

[0026] (4) Accurate drug delivery can be achieved through dynamic monitoring results, avoiding extensive manual rowing-style drug delivery, avoiding water environment problems caused by excessive or insufficient drug delivery, reducing labor costs, and reducing work intensity.

[0027] (5) By integrating multiple sensors (such as turbidity, dissolved oxygen, pH, ammonia nitrogen, nitrite, etc.), combined with a six-way pipe and mixed drug dosing structure, intelligent proportioning and precise dosing of drugs are achieved. The microporous aerator at the bottom of the device effectively increases the dissolved oxygen in the water, enabling the device to fully complete the tasks of water quality monitoring and improvement at the same time.

[0028] (6) Users can monitor the water quality of fish ponds in real time through the cloud monitoring platform. When the water quality in a certain area is abnormal, the device can be awakened to improve the water quality at a specific point. This invention provides a smart aquaculture solution that can be monitored, controlled and adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] See also Figure 1 The present invention provides an aquaculture proportioning feeder. The device is 100 cm long, 120 cm wide, and 40 cm high, with a small size and can move flexibly on the water surface. The water quality dynamic detection device is used to collect water surface and water quality information, and the liquid medicine intelligent proportioning device proportions the liquid medicine as needed. The precise delivery device delivers the liquid medicine evenly and continuously to the designated location. The bionic propulsion structure ensures that the device remains stable and moves effectively when performing tasks.

[0041] like Figure 1As shown, the present invention provides a device for dynamic water quality monitoring and drug proportioning and delivery, the device comprises a solar panel telescopic energy supply system, below which are a drug liquid proportioning structure (9), a drug liquid delivery structure (35), a water quality detection structure (1) and a bionic propulsion structure (11). The components cooperate closely to achieve dynamic monitoring of water quality, intelligent proportioning and precise delivery of drug liquid, and the autonomous propulsion function of the device.

[0042] like Figure 1 As shown, the water quality detection structure (1) is installed in front of the device. The module is used to monitor water quality parameters such as pH, dissolved oxygen, ammonia nitrogen, nitrite and turbidity of the water body in real time. A sensor information collection module (66) is arranged inside the deck (16), and water samples are extracted from the pond or pool for testing through a water pump (18). The water sample can be transported to the medicine liquid tank (27) for storage through an auxiliary delivery tube (42), or it can be directly discharged to obtain the latest water quality data and upload it to the cloud supervision platform. The water quality detection structure (1) monitors the water surface conditions, water speed and hull balance information in real time through the power rocker (8) rocker mechanism in front. All collected data are processed by the sensor information collection module (66) and used for decision support for drug proportioning and delivery to ensure the quality of the aquaculture environment.

[0043] The liquid medicine proportioning structure (9) can automatically adjust the dosage and proportion of the medicine according to the water quality monitoring results. Through the data feedback of the sensor collection information module (66), the liquid medicine proportioning structure (9) can automatically adjust the corresponding liquid medicine concentration and amount. The electromagnetic integrated valve (28) is opened or closed as needed, and the negative pressure pump (29) pumps the liquid medicine into the liquid medicine proportioning chamber (13). At the same time, the dissolved oxygen content in the water body will affect the operation of the aerator (70). This automated setting ensures the uniformity and accuracy of the medicine dosage and reduces manual intervention.

[0044] The liquid medicine delivery structure (35) pushes the medicine to the delivery port and sprays it at a set rate. The liquid medicine proportioning structure (9) controls the flow of the liquid medicine through the medicine plug (52), and automatically selects and proportions the appropriate liquid medicine according to different acidity and storage conditions. Under the control of the electromagnetic integrated valve (28), the liquid medicine in the liquid medicine warehouse (27) is extracted into the liquid medicine proportioning chamber (13). In the proportioning chamber, the fan blades (43) driven by the high-speed motor (104) fully mix the liquid medicine, and the two-way valve (76) controls the delivery amount and delivery speed. The liquid pumping booster pump (34) accelerates the delivery of the liquid medicine, and delivers the liquid medicine to the special nozzle (19) located at the bottom of the ship's warehouse through the liquid outlet pipe (36) to achieve uniform and continuous spraying. The pressure is adjusted by the water pump (18), and the injection rate of the nozzle (19) can be accurately controlled to ensure that the liquid medicine is accurately delivered to the target area. The structure is designed to efficiently and accurately deliver medicine or other materials to aquaculture waters. The entire delivery process is monitored in real time by the control device, which adjusts the working state of the air pressure device according to actual needs and accurately controls the delivery speed and spraying amount.

[0045] The water quality detection structure (1) can obtain and analyze water quality parameters in real time, and the data is fed back to the control device. The environment detection device is composed of a top camera module (51) and a water quality detection structure (1) to collect surrounding environment information, including water surface amplitude, water speed and water flow direction. All collected data will be transmitted to the sensor information collection module (66) and provided to the control device for instruction processing.

[0046] The bionic propulsion structure (11) is composed of a floating plate adjustment module (22) and a double propeller (31). The structure adjusts the center of gravity and balance of the device according to the data collected by the environment detection device and the water quality detection structure (1). The motor (12) drives the machine bar (14) to drive the power rocker (8) to perform rocker movement, change the tilt angle of the device, and maintain balance. At the same time, the rear double propeller (31) realizes flexible direction control by adjusting the rotation speed and steering, ensuring the stable movement of the device.

[0047] The air pressure device controls the injection of the liquid medicine by controlling the compressed air of the air source. When the air pressure device generates sufficient pressure, the liquid medicine is pushed out of the nozzle (19). The nozzle (19) can spray the liquid medicine evenly in a specific aquaculture area in an atomized or appropriate form.
