Description

TECHNICAL FIELD

[0001] The present application relates to a water quality dynamic monitoring and medicament proportioning and feeding technology, and belongs to the technical field of fishery culture. BACKGROUND

[0002] With the continuous improvement of people's living standards, the demand for aquatic products is increasing. Fishery culture 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 fishery culture industry in China has low automation. When the water quality of the fish pond is problematic, manual sampling and detection of water quality and extensive throwing of medicaments are used to improve the water quality. This can easily lead to overuse of medicaments, resulting in water eutrophication and further inhibiting the growth of aquatic products. On the other hand, insufficient use of medicaments can not effectively improve the water environment, and aquatic products still grow in a diseased environment. Fishery culture has the problems of untimely water quality monitoring, inaccurate medicament addition, and low efficiency of manual medicament feeding, resulting in the problem of high risk of fishery culture.

[0004] In the prior art, attempts have been made to improve the environment for aquatic product culture by setting up an automatic medicament feeding machine to optimize the water quality environment. For example, the patent application for an invention with publication number CN107347751A discloses an automatic medicament feeding machine for fish culture. The device pours the medicament into the medicament tank of the feeding machine, turns on the motor, uses the pressure difference between the stirring tank and the outside to suck the medicament and water in the fish pond into the stirring tank for mixing, and then uses the water pump to deliver the mixed medicament to the spray head through the liquid outlet pipe to achieve automatic and uniform medicament feeding. However, the disadvantage of this device is that it only solves the problem of replacing manual medicament feeding and cannot adjust the amount of medicament feeding according to the actual situation of the water quality. Therefore, it cannot accurately improve the water quality and cannot dynamically adjust according to the growth environment of aquatic products, has low precision, limited automation, and still has the problem of unreasonable medicament feeding.

[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 control. For example, the invention patent application with publication number CN117837548A discloses a water quality multi-node online monitoring and control device. 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 dosing machine to release the improved reagent according to the monitoring results. Although this technology realizes dynamic reagent control based on water quality monitoring results, there are still some obvious problems. First, in order to adapt to different shapes and sizes of ponds, a large number of water quality monitoring nodes need to be deployed, which is costly and complex to maintain. Second, the location of the dosing machine is fixed, while the water in 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 reagent according to the water quality data, and it is difficult to achieve precise adjustment of the reagent dosage, resulting in unstable drug efficacy and inability to fully meet the needs of fine management of water quality.

[0006] From the above analysis, it can be seen that the existing fishery breeding reagent dispensing device and water quality monitoring and control device cannot realize intelligent proportioning and precise dispensing of reagents based on the results of water quality monitoring. Many water quality monitoring nodes need to be installed to collect data, and multiple dosing machines need to be deployed to release the improved reagent, which is very costly. The hardware installation and deployment location is fixed, the water flow in the pond is poor, which is not conducive to real-time and accurate acquisition of water quality parameters in the fish pond and remote control. It cannot make aquatic products always in the most suitable growth environment. SUMMARY

[0007] Technical problem: In view of the above technical deficiencies, the present application mainly proposes a water quality dynamic monitoring and reagent proportioning and dispensing device for aquaculture, which can simultaneously realize three core functions of water quality dynamic monitoring, intelligent reagent proportioning, and precise dispensing.

[0015] The reagent mixing warehouse is installed in the middle of the alloy partition, and the reagent warehouses extending downward from above are placed on both sides. The liquid extraction booster pumps are located on the front and back of the alloy partition, and the four double-way valves are symmetrically distributed on the left and right sides of the reagent warehouses.

[0016] The floating plate adjustment module is symmetrically installed on both sides of the device, the motor is located in the first quadrant and the third quadrant of the clamp plate, directly connected to the power rocker and interference fit, and the battery is installed inside the deck to provide power for the motor.

The bottom detection module is immersed in 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 fluctuation and water speed, and automatically adjust the posture and direction of the device during movement, to ensure its stability and balance.

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

[0020] The dissolved oxygen injection device includes a three-way flange, left and right connecting pipe-type aerators, and a third end connected to the gas injection device at the bottom of the deck. Four pipe-type aerator assemblies are symmetrically distributed on the left and right front and back of the device, and a diaphragm-type aerator is installed at the bottom center. When the device moves on the water surface, it injects dissolved oxygen into the water body through the cooperation of the air pump and various structures.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1 This invention provides an aquaculture feed dispensing machine. The device is 100cm long, 120cm wide, and 40cm high, compact in size, and can move flexibly on the water surface. A water quality dynamic monitoring device collects water surface and water quality information, while an intelligent drug dispensing device dispenses the required amount of medicine. A precise dispensing device evenly and continuously dispenses the medicine to the designated location. A biomimetic propulsion structure ensures the device remains stable and moves effectively during operation.

[0041] like Figure 1As shown, this invention provides a water quality dynamic monitoring and reagent dosage device. The device includes a solar panel telescopic power supply system, below which are a reagent dosage structure (9), a reagent dosage structure (35), a water quality detection structure (1), and a biomimetic propulsion structure (11). The components work closely together to achieve dynamic monitoring of water quality, intelligent dosage and precise dosage of reagents, and autonomous propulsion of the device.

[0042] like Figure 1 As shown, the water quality detection structure (1) is installed at the front of the device. This module is used to monitor water quality parameters such as pH, dissolved oxygen, ammonia nitrogen, nitrite, and turbidity in real time. The deck (16) is equipped with a sensor information collection module (66), which draws water samples from ponds or pools for testing via a water pump (18). The water samples can be transported to the drug storage tank (27) via the auxiliary pipe (42) for storage, or they can be discharged directly to obtain the latest water quality data and upload it to the cloud monitoring platform. The water quality detection structure (1) is monitored in real time by a rocker arm mechanism (8) to monitor the water surface, water speed, and hull balance information. All collected data is processed by the sensor information collection module (66) and used for decision support in drug formulation and administration to ensure the quality of the aquaculture environment.

[0043] The chemical dosing structure (9) can automatically adjust the dosage and ratio of the chemicals based on water quality monitoring results. Through data feedback from the sensor-collected information module (66), the chemical dosing structure (9) can automatically adjust the corresponding concentration and amount of chemicals. The electromagnetic integrated valve (28) opens or closes as needed, and the negative pressure pump (29) draws the chemicals into the chemical dosing chamber (13). Simultaneously, the dissolved oxygen content in the water affects the operation of the aerator (70). This automated setup ensures the uniformity and accuracy of chemical dosing, reducing manual intervention.

[0044] The drug liquid delivery structure (35) pushes the drug to the delivery port and sprays at a set rate. The drug liquid proportioning structure (9) controls the flow of drug liquid through the drug plug (52), automatically selects and proportionally mixes appropriate drug liquid according to different acid-base and storage conditions. The drug liquid in the drug liquid tank (27) is controlled by the electromagnetic integrated valve (28), and the appropriate amount of drug liquid is extracted to the drug liquid proportioning chamber (13). In the proportioning chamber, the fan blade (43) driven by the high-speed motor (104) fully mixes the drug liquid, and the two-way valve (76) controls the delivery amount and delivery speed. The liquid extraction booster pump (34) accelerates the delivery of the drug liquid, and the drug liquid is sent to the special nozzle (19) located at the bottom of the ship tank through the liquid outlet pipe (36), realizing uniform and continuous spraying. The injection rate of the nozzle (19) is accurately controlled by adjusting the pressure of the water pump (18), ensuring that the drug liquid is accurately delivered to the target area. The structure aims to efficiently and accurately deliver drugs or other materials to aquaculture water. 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, 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 environmental detection device cooperates with the water quality detection structure (1) to collect surrounding environmental 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). According to the data collected by the environmental detection device and the water quality detection structure (1), the device adjusts the center of gravity and balance. The motor (12) drives the crank (14) to drive the power rocker (8) to perform rocker motion, changing the inclination angle of the device and maintaining balance. At the same time, the rear double propeller (31) adjusts the speed and direction to realize flexible direction control, ensuring stable movement of the device.

[0047] The air pressure device controls the delivery of drug liquid by controlling the compressed air of the air source. When the air pressure device generates sufficient pressure, the drug liquid is pushed out of the nozzle (19). The nozzle (19) can uniformly spray the drug liquid in the form of atomization or appropriate form to the specific aquaculture area.
