Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture water temperature control equipment, and in particular to a water temperature control equipment for Litopenaeus vannamei aquaculture. Background Technology

[0002] As an important aquaculture species, the Pacific white shrimp has strict requirements for water temperature for its growth and reproduction. Suitable water temperature can promote the metabolism of Pacific white shrimp, increase feeding rate and growth rate, thereby improving the yield and quality of farmed shrimp. Therefore, water temperature control equipment plays a crucial role in the farming of Pacific white shrimp.

[0003] In the prior art, such as the water temperature control device for Litopenaeus vannamei farming disclosed in CN222548383U, which belongs to the field of aquaculture equipment technology, this device achieves the switching between cold and hot water and the regulation of water volume through the setting of a flow regulation mechanism. It can regulate the water temperature in the farming tank to ensure a suitable farming temperature. At the same time, this device realizes water recycling and diverts the circulating water for heating or cooling, improving water utilization efficiency and preventing excessively high water levels in the farming tank, thus improving the farming effect of Litopenaeus vannamei to a certain extent.

[0004] However, in practical applications, the aforementioned existing technical solutions have significant shortcomings. This approach is not conducive to the decentralized delivery of regulated water, making it difficult for the regulated cold or hot water to mix fully and evenly with the aquaculture water upon entry. This may result in localized excessively high or low water temperatures in the aquaculture water, affecting the growth environment of the Pacific white shrimp and even causing stress responses, thus impacting their health and growth.

[0016] 2. Precise water temperature control ensures a stable aquaculture environment: This invention uses a temperature sensor to monitor the delivered water temperature in real time and transmits the temperature as an electrical signal to the PLC controller.

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Please refer to Figures 1 to 3 As shown, an embodiment of this utility model provides a water temperature control device for Litopenaeus vannamei farming, including: a heater 1 and a cooler 2. Both the heater 1 and the cooler 2 are equipped with water inlet pipes 3011 on their sides. The two water inlet pipes 3011 are connected by a tee 301. A delivery pump 3 is installed on the side of the tee 301. A dispersion component 4 for water dispersion is installed on the side of the delivery pump 3 away from the tee 301.

[0031] By adopting the above technical solution, the temperature sensor 4021 monitors the delivery water temperature in real time and transmits the signal to the PLC controller 4022. The PLC controller 4022 then precisely controls the solenoid valves 4023 on the side inlet pipes 3011 of the heater 1 and the cooler 2 to adjust the delivery volume of cold and hot water in real time, ensuring that the aquaculture water is at a suitable temperature. When the delivery pump 3 is working, the waterproof motor 40111 drives the dispersion plate 40112 and its dispersion blades 40113 to rotate, so that the regulated water is evenly dispersed and integrated into the aquaculture water, avoiding local water temperature differences. The water temperature regulation is automated by using components such as the temperature sensor 4021, the PLC controller 4022, and the solenoid valves 4023, reducing labor costs and labor intensity, and improving regulation efficiency and accuracy. The overall structural design is reasonable, and the components work together to improve the reliability and durability of the equipment, reduce failures, lower maintenance costs, and extend service life, providing long-term and stable water temperature regulation for Litopenaeus vannamei aquaculture.

[0032] To achieve uniform mixing of the regulated water and the aquaculture water, in this embodiment, the dispersion component 4 includes a water storage frame 401, on which a dispersion structure 4011 for water dispersion is installed. The water storage frame 401 provides space for water dispersion, while the dispersion structure 4011 directly disperses the water entering the water storage frame 401. During the temperature control process in Litopenaeus vannamei aquaculture, if the regulated cold or hot water cannot be uniformly mixed when it enters the aquaculture water, it will lead to large local temperature differences, affecting shrimp growth. By setting up the dispersion structure 4011, this problem can be effectively improved, ensuring thorough mixing of the regulated water and the aquaculture water, guaranteeing uniform temperature in the aquaculture water, and creating a favorable growth environment for the shrimp.

[0033] To ensure smooth water flow between the delivery pump 3 and the dispersion component 4, in this embodiment, a connecting pipe 402 is installed on the side of the water storage frame 401, and the water storage frame 401 is connected to the side of the delivery pump 3 through the connecting pipe 402. The connecting pipe 402 serves to connect the delivery pump 3 and the water storage frame 401, ensuring that the water delivered by the delivery pump 3 can smoothly enter the water storage frame 401 for dispersion treatment. This connection method ensures the continuity and stability of water delivery, avoids problems such as leakage or blockage during water delivery, and improves the operating efficiency of the entire water temperature control equipment.

[0034] To provide the power for water dispersion, in this embodiment, the dispersion structure 4011 includes a waterproof motor 40111 fixedly connected to the water storage frame 401. A dispersion disc 40112 is mounted on the output shaft of the waterproof motor 40111. The waterproof motor 40111, fixedly connected to the water storage frame 401, provides power for the rotation of the dispersion disc 40112. During the temperature control process in Litopenaeus vannamei aquaculture, it is necessary to uniformly disperse the controlled water. The waterproof motor 40111 can operate stably, driving the dispersion disc 40112 to rotate, thereby achieving the dispersion effect on the water. Its waterproof performance also ensures normal operation in a humid aquaculture environment, improving the reliability and durability of the equipment.

[0035] To enhance water dispersion and improve mixing uniformity with the aquaculture water, in this embodiment, a plurality of dispersing blades 40113 are installed on the dispersing disc 40112 at equal intervals. When the dispersing disc 40112 rotates under the drive of the waterproof motor 40111, the dispersing blades 40113 can more thoroughly stir and disperse the water. The design of multiple dispersing blades 40113 increases the contact area with the water, enabling more effective dispersion of the controlled water and better mixing with the aquaculture water, further ensuring the uniformity of the aquaculture water temperature, which is beneficial to the growth of Litopenaeus vannamei.

[0036] To achieve precise water temperature control, in this embodiment: a temperature sensor 4021 is installed at the bottom of the connecting pipe 402; a PLC controller 4022 electrically connected to the temperature sensor 4021 is installed on the heater 1; and a solenoid valve 4023 electrically connected to the PLC controller 4022 is installed on the inlet pipe 3011. The temperature sensor 4021, installed at the bottom of the connecting pipe 402, can monitor the delivered water temperature in real time and transmit the water temperature to the PLC controller 4022 in the form of an electrical signal. Based on preset water temperature parameters, the PLC controller 4022 precisely controls the solenoid valve 4023 on the side inlet pipe 3011 of the heater 1 and the cooler 2, adjusting the delivery volume of cold and hot water in real time. This precise water temperature control method ensures that the aquaculture water is always maintained within a suitable temperature range for the growth of Litopenaeus vannamei, improving the aquaculture effect.

[0037] Among them, the temperature sensor 4021 is a sensor with model number RK500-01, the PLC controller 4022 is a CPU1214C controller of Siemens S7-1200 series, and the solenoid valve 4023 is a solenoid valve with model number EV220A.

[0038] The working principle of this utility model is as follows:

[0039] In the process of water temperature control for Litopenaeus vannamei farming, heater 1 and cooler 2 are responsible for providing cold water and hot water, respectively, to meet different water temperature regulation needs. Simultaneously, temperature sensor 4021 at the bottom of connecting pipe 402 monitors the delivered water temperature in real time and transmits the water temperature data as an electrical signal to PLC controller 4022 on heater 1. Based on preset water temperature parameters, PLC controller 4022 precisely controls the solenoid valves 4023 on the side inlet pipes 3011 of heater 1 and cooler 2 to achieve real-time adjustment of the cold and hot water delivery rates, ensuring that the farming water temperature remains stable within a suitable range.

[0040] The delivery pump 3 delivers water to the storage frame 401. During this process, the waterproof motor 40111 is turned on, which drives the dispersing disc 40112 on the output shaft to rotate. The dispersing blades 40113 on the dispersing disc 40112 thoroughly stir and disperse the water entering the storage frame 401. This dispersion process ensures that the regulated cold or hot water is evenly mixed with the aquaculture water, avoiding excessive local temperature differences. This creates a uniform and stable growth temperature environment for the Litopenaeus vannamei, which helps improve the yield and quality of the shrimp.
