Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an intelligent breeding device for shrimp. Background Technology

[0002] As a globally important aquaculture species, shrimp farming plays a pivotal role in the fisheries economy of my country and the world. According to relevant data, my country's shrimp production has continued to grow in recent years, meeting domestic market demand while also exporting large quantities, generating considerable foreign exchange earnings for the country. With consumers' increasing demands for shrimp quality and intensifying market competition, the breeding of superior shrimp varieties has become a crucial link in enhancing industry competitiveness and ensuring sustainable development.

[0003] However, in the current technology, it is difficult to monitor various parameters of the breeding environment in real time and comprehensively during the shrimp breeding process. The growth and development of shrimp are closely related to environmental factors such as water quality (such as dissolved oxygen content, temperature, pH value, salinity, etc.) and light. Under the traditional breeding method, farmers can usually only conduct intermittent water quality testing and cannot obtain information on the dynamic changes of environmental parameters in a timely manner. Once the environment becomes abnormal, such as water quality deterioration or sudden temperature changes, effective adjustment measures cannot be taken in time, which will not only affect the normal growth of shrimp, but also lead to the occurrence and spread of diseases, thereby affecting the breeding effect and increasing the breeding risk.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an intelligent breeding device for shrimp, including a breeding box 1. A detachable long plate 11 is installed on the upper end of the breeding box 1. A control system 12 is arranged on one side of the breeding box 1. A dissolved oxygen sensor 13, a temperature sensor 14, a pH sensor 15, and a salinity sensor 16 are installed sequentially from left to right on the lower end of the long plate 11. L-shaped brackets 17 are installed at both ends of the breeding box 1. Image acquisition components 18 are fixedly installed on the end faces of the two sets of L-shaped brackets 17. A circulation mechanism 2 is arranged at one end of the breeding box 1. A sorting mechanism 3 is arranged on both sides of the breeding box 1. The dissolved oxygen sensor 13, temperature sensor 14, pH sensor 15, salinity sensor 16, and the two sets of image acquisition components 18 are all connected to the control system 12.

[0023] The circulation mechanism 2 includes a fixed plate 21. A filter assembly 22 and a water pump 23 are fixedly installed on the upper end of the fixed plate 21. A connecting pipe 24 is fixedly installed on the outlet end of the water pump 23. A special-shaped connecting pipe 25 is fixedly installed on the outlet end of the filter assembly 22. A long pipe 26 is fixedly installed on the inlet end of the water pump 23. The lower end of the control system 12 is fixed to the upper end of the filter assembly 22. The other end of the long pipe 26 extends into the interior of the breeding box 1. The other end of the special-shaped connecting pipe 25 is located inside the breeding box 1. One end of the fixed plate 21 is fixed to one end of the breeding box 1.

[0024] The specific setup and function of this embodiment are described in detail below. The overall device uses the breeding box 1 as the core breeding carrier. A detachable long plate 11 is set at the upper end of the breeding box 1. The long plate 11 is made of high-strength, corrosion-resistant engineering plastic material and is connected to the pre-drilled screw holes at the top edge of the breeding box 1 by bolts. This detachable design facilitates the maintenance, replacement or upgrading of the sensors in the later stage. At the lower end of the long plate 11, a dissolved oxygen sensor 13, a temperature sensor 14, a pH sensor 15 and a salinity sensor 16 are installed in sequence. The upper part of each sensor is equipped with a waterproof protective shell with a waterproof connector for connecting to the external signal line. The lower part of the sensor is a sensing probe that directly penetrates into the internal water of the breeding box 1 to ensure that various water quality parameters of the breeding water can be monitored in real time and accurately. In addition, these sensors are all connected to the control system 12. To ensure the stability and accuracy of signal transmission, the monitored data such as dissolved oxygen content, temperature, pH value and salinity are transmitted to the control system 12 in real time.

[0025] At both ends of the breeding box 1, two sets of L-shaped brackets 17 are installed. The L-shaped brackets 17 are made of stainless steel and have good strength and corrosion resistance. The vertical part is fixed to the outer wall of the breeding box 1 by welding, while the horizontal part is used to install the image acquisition components 18. The image acquisition components 18 include a high-definition camera and an adjustable LED supplement light. The lenses of the two sets of image acquisition components 18 are aimed at the inside of the breeding box 1 to take pictures of the growth status of the shrimp in the box from different angles, and to obtain image information such as the size, color and activity of the shrimp. The images are then transmitted to the control system 12 via a data cable.

[0026] The control system 12 has a built-in high-performance processor and a large-capacity storage unit. The storage unit contains pre-stored standard data on shrimp growth indicators and water quality standards. The processor uses advanced image recognition algorithms to analyze and process the images transmitted by the image acquisition component 18, and automatically measures the shrimp's body length, weight, and other growth indicators. At the same time, it analyzes the received water quality monitoring data and compares the shrimp growth indicators and water quality data with the pre-stored standard data. When the shrimp growth indicators meet the preset breeding standards and the water quality data is within the normal range, the control system 12 sends a command to the automatic sorting module to start the shrimp sorting process.

[0027] The improved device enables flexible and accurate monitoring of water quality parameters. The design of the L-shaped bracket 17 and the image acquisition component 18 ensures comprehensive acquisition of shrimp growth information. The two work together to enable the control system 12 to acquire shrimp growth information and water quality data inside the breeding box 1 in real time, and then automatically select shrimp that meet the standards. Compared with traditional breeding methods, this greatly improves breeding efficiency and accuracy, reduces manual intervention, and reduces labor intensity, providing strong support for efficient and accurate shrimp breeding.

[0028] A fixing plate 21 is fixedly installed at one end of the breeding box 1. The fixing plate 21 is made of high-strength and corrosion-resistant engineering plastic material. Its size is adapted to the end of the breeding box 1. It is firmly connected to the side wall of the breeding box 1 by bolts to ensure stability during equipment operation. The fixing plate 21 serves as the mounting carrier for the filter assembly 22 and the water pump 23, providing solid support for both.

[0029] The water pump 23 is a low-noise, high-lift variable frequency water pump. Its inlet end is tightly connected to the long pipe 26. The long pipe 26 is made of food-grade PVC material. The pipe diameter is scientifically designed according to the flow rate of the water pump 23 to ensure smooth water flow. The long pipe 26 extends into the breeding box 1. A filter screen is installed at the end to prevent shrimp or debris from entering and clogging the pipe. When the water pump 23 starts, the pumping flow rate can be flexibly adjusted through the variable frequency control to draw the culture water in the breeding box 1 through the long pipe 26.

[0030] The filter assembly 22 is the core of the entire filtration system. It adopts a multi-layer composite filtration structure. The outermost layer is a coarse filter layer, which is composed of a stainless steel filter screen with a large pore size. It can intercept larger suspended solids, uneaten food, and feces in the water. The middle layer is an activated carbon adsorption layer, which is made of high-quality coconut shell activated carbon. It can effectively adsorb pigments, odors, and some harmful substances in the water by utilizing its rich pore structure. The innermost layer is a precision filter layer, which adopts a hollow fiber ultrafiltration membrane. It can filter out tiny bacteria, colloids, and some organic pollutants. The top of the filter assembly 22 is equipped with a quick-release maintenance cover, which is convenient for regular cleaning and replacement of filter materials. The aquaculture water drawn by the water pump 23 is sent into the filter assembly 22 through the connecting pipe 24. Under pressure, the water passes through each layer of filter material in sequence, realizing a multi-stage purification process from coarse filtration to fine filtration.

[0031] The drain end of the filter assembly 22 is equipped with a special-shaped pipe 25, which is made of corrosion-resistant PPR material. One end of the pipe is tightly connected to the outlet of the filter assembly 22, and the other end is bent and extended to the upper part of the breeding box 1. In order to make the purified water evenly distributed, the part of the special-shaped pipe 25 located inside the breeding box 1 is provided with multiple small water outlet holes, which are arranged in a fan shape to ensure that the water flow is dispersed and covers the entire breeding area.

[0032] The entire filtration system forms a closed-loop water circulation and purification system through the coordinated operation of water pump 23, long pipe 26, connecting pipe 24, filter component 22, and special-shaped connector 25. When water pump 23 is running, the aquaculture water is drawn from the breeding tank 1, purified by the filter component 22, and then reinjected into the breeding tank 1 through the special-shaped connector 25, continuously maintaining the cleanliness of the aquaculture water. This system can not only effectively remove impurities and harmful substances from the water and maintain water quality stability, but also reduce the occurrence of shrimp diseases caused by water quality deterioration, providing an excellent growth environment for shrimp breeding and improving the quality and efficiency of shrimp breeding.

[0033] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, the sorting mechanism 3 includes two sets of support frames 31. Robotic arms 32 are fixedly installed on the upper ends of both sets of support frames 31. Shrimp suction components 33 are fixedly installed at the ends of both sets of robotic arms 32. Both sets of shrimp suction components 33 are located above the breeding box 1. One side of each set of support frames 31 is fixed to the two sides of the breeding box 1. A sewage discharge mechanism 10 is installed through the lower end of the breeding box 1.

[0034] The overall effect of this embodiment is that two sets of support frames 31 are symmetrically installed on the outer walls of both sides of the breeding box 1. The support frames 31 are made of high-strength aluminum alloy and are firmly connected to the breeding box 1 by pre-embedded bolts. An industrial-grade six-axis robotic arm 32 is vertically installed on the upper surface of each set of support frames 31. The robotic arm 32 is selected with a load capacity of 5kg and a repeatability of ±0.05mm. Its joints are equipped with high-precision servo motors and reducers to ensure the stability and accuracy of the movement. The end effector connection end of the robotic arm 32 adopts a quick-change interface design to facilitate the quick replacement of different types of shrimp suction components 33.

[0035] The shrimp suction assembly 33 consists of a shrimp suction head, a flexible connecting tube 24, and a negative pressure generating device. The shrimp suction head is made of medical-grade silicone material and has a funnel-shaped structure to prevent damage to the shrimp during the grasping process. The shrimp suction head is embedded with a pressure sensor, which can monitor the suction pressure in real time to avoid injury to the shrimp due to excessive pressure. The flexible connecting tube 24 is made of transparent PVC material, which has good flexibility and corrosion resistance. One end of it is sealed to the shrimp suction head, and the other end is connected to the negative pressure generating device. The negative pressure generating device uses a miniature vacuum pump. The working parameters of the pump can be adjusted by the control system 12 to precisely control the amount of negative pressure when suctioning the shrimp.

[0036] Both sets of robotic arms 32 and shrimp suction components 33 establish real-time communication connections with the control system 12 via industrial Ethernet. When the control system 12 determines that a certain shrimp meets the breeding standards through image analysis and water quality monitoring, it first calculates the precise position of the target shrimp in three-dimensional space based on the coordinate information provided by the image acquisition component 18. Then, it sends a motion command to the corresponding robotic arm 32. The robotic arm 32 moves the shrimp suction component 33 quickly and smoothly to about 5cm above the target shrimp according to the preset trajectory planning algorithm. At this time, the control system 12 controls the operation of the shrimp suction component 33, which gently sucks up the target shrimp. Then, the robotic arm 32 moves the shrimp suction component 33 to the sorting channel entrance on one side of the breeding box 1 according to the preset path. After reaching the designated position, the control system 12 reduces the negative pressure and puts the shrimp into the sorting channel to complete one sorting operation.

[0037] To improve sorting efficiency, the two sets of robotic arms 32 can work together to sort shrimp in different areas of the breeding box 1. At the same time, the control system 12 can dynamically adjust the working mode of the robotic arms 32 and the suction parameters of the shrimp suction component 33 according to the distribution density and growth of the shrimp.

[0038] The device's operation and working principle are as follows: First, the dissolved oxygen sensor 13, temperature sensor 14, pH sensor 15, and salinity sensor 16 monitor the water quality inside the breeding tank 1. Then, the monitored data, including dissolved oxygen content, temperature, pH, and salinity, are transmitted in real-time to the control system 12. Next, the control system 12 controls the water pump 23 to operate, drawing aquaculture water from the breeding tank 1. After purification by the filter assembly 22, the water is reinjected into the breeding tank 1 through the special-shaped connector 25, continuously maintaining the cleanliness of the aquaculture water and providing an excellent growth environment for shrimp breeding, thus improving the quality and efficiency of shrimp breeding. Finally, the water quality is monitored by two sets of image acquisition components 18. The situation inside box 1 is monitored in real time, and the data is continuously transmitted to the control system 12. After calculation, the control system 12 controls the operation of two sets of robotic arms 32 and two sets of shrimp suction components 33. The robotic arms 32 move the shrimp suction components 33 quickly and smoothly above the target shrimp according to the preset trajectory planning algorithm. At this time, the control system 12 controls the operation of the shrimp suction components 33, which gently sucks up the target shrimp. Then, the robotic arms 32 move the shrimp suction components 33 to the entrance of the sorting channel on one side of the breeding box 1 according to the preset path. After reaching the designated position, the control system 12 reduces the negative pressure and puts the shrimp into the sorting channel to complete one sorting operation.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
