Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling equipment technology, and in particular to a water cooling device for aquaculture. Background Technology
[0002] In the breeding of ornamental fish and other aquatic organisms, stable water temperature is crucial. Suitable water temperature is a key factor for the healthy growth, normal metabolism and reproduction of aquatic organisms. Water temperature that is too high or too low may have adverse effects on their physiological functions, and may even lead to disease outbreaks or death.
[0003] In practical applications, the ambient temperature of fish habitats is easily affected by various factors such as seasons and weather changes, leading to significant fluctuations in water temperature. Especially during the high-temperature period of summer, as temperatures rise, the water temperature in the fish's environment also rises. If cooling is not effective and timely, it will seriously threaten the survival of the fish. A common cooling method is to use fans to accelerate airflow over the water surface, promoting water evaporation and heat absorption. While this method has the advantage of low energy consumption, its cooling effect is limited, and it can only remove heat from the surface of the water. Utility Model Content
[0004] In order to overcome the limited cooling effect of existing fish farming containers, this utility model provides a water-diverting and cooling device for aquaculture.
[0005] The technical solution is as follows: an aquaculture water cooling device, including a water pump, a water supply pipe, a mounting frame, a cooling frame, a drain pipe, a fixing frame, and a first fan. The mounting frame is provided on the cooling frame, the water supply pipe is provided on the cooling frame and connected to the water pump, the drain pipe is provided on the cooling frame and its opening is higher than the bottom of the cooling frame but lower than the frame edge, and the first fan is installed on the fixing frame.
[0006] Furthermore, it also includes a temperature sensor, a connecting cable, and a display, with the temperature sensor and the display connected by a connecting cable.
[0007] Furthermore, it also includes a first adjusting bolt and a second adjusting bolt, with the first adjusting bolt threaded onto the mounting bracket and the second adjusting bolt threaded onto the fixing bracket.
[0008] Furthermore, it also includes a first air outlet frame, on which the first fan is provided, and on which the first air outlet frame is provided an air outlet, which is flat in shape.
[0009] Furthermore, it also includes a second fan and a second air outlet frame. The second fan is installed on the fixed frame, the second fan is equipped with the second air outlet frame, and the second air outlet frame is equipped with an air outlet, which is flat in shape.
[0010] Furthermore, the cooling frame is equipped with a drain outlet, which is located at the lowest point of the water storage area inside the cooling frame.
[0011] Furthermore, the cooling frame is provided with 3 to 5 units, and the number of air outlets of the first air outlet frame is the same as that of the cooling frame.
[0012] Furthermore, the drain pipe is located at the corner of the cooling frame, and the drain pipes of adjacent cooling frames are located at opposite corners, with the bottom of the drain pipe lower than the top of the adjacent lower drain pipe.
[0013] Furthermore, it also includes valves; valves are installed on the water supply pipes.
[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a multi-layer cooling frame design, in which water flows from top to bottom through each cooling frame layer by layer, forming multiple continuous cooling segments, significantly extending the water cooling path, significantly improving the overall cooling efficiency, and ensuring that the final return water temperature is greatly reduced.
[0015] 2. This utility model uses a temperature sensor to detect the temperature of the water in the fish tank in real time and displays the temperature on a monitor. Users can intuitively and instantly understand the temperature status of the water in the fish tank, making it easier to determine when to start the cooling device and evaluate the cooling effect, thus achieving precise temperature control.
[0016] 3. The design of the first and second adjusting bolts allows for flexible adjustment of the clamping force of the mounting bracket and the fixing bracket on the fish farming container, adapting to fish farming containers of different sizes and edge thicknesses, thus improving the versatility and installation stability of the device.
[0017] 4. By staggering the vertical positions of the drain pipes of adjacent cooling frames, this utility model prevents the water from flowing directly into the drain pipe of the lower layer, ensuring that the water fully contacts the cold air in each layer before entering the next layer, thus maximizing the heat exchange efficiency.

[0024] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] A water cooling device for aquaculture, such as Figures 1-5 As shown, the container includes a water pump 5, a water supply pipe 6, a valve 7, a mounting bracket 8, a cooling frame 9, a drain pipe 10, a fixing bracket 13, a first fan 14, and a first air outlet bracket 15. The water pump 5 is installed at the bottom inside the fish tank 1. The water outlet of the water pump 5 is equipped with a water supply pipe 6. A valve 7 is installed on the water supply pipe 6. The mounting bracket 8 is installed on the fish tank 1. The mounting bracket 8 is equipped with a cooling frame 9. There are 3 to 5 cooling frames 9. The water supply pipe 6 is connected to the uppermost cooling frame 9. The cooling frame 9 is equipped with a drain pipe 10. The pipe opening is higher than the bottom of the water storage area inside the cooling frame 9, but lower than the top of the cooling frame 9. The fixing bracket 13 is installed on the fish tank 1. The first fan 14 is installed on the fixing bracket 13. The first air outlet bracket 15 is installed on the first fan 14. The first air outlet bracket 15 is equipped with multiple air outlets.
[0026] When the temperature inside the fish tank 1 is too high, the water pump 5 transports water from the bottom of the fish tank 1 to the top cooling frame 9 through the water pipe 6. The valve 7 on the water pipe 6 controls the water flow. Water begins to accumulate inside the cooling frame 9. When the water level exceeds the height of the drain pipe 10, the water flows out from the drain pipe 10 and falls into the adjacent cooling frame 9 below, undergoing the same water accumulation and overflow process. This process continues layer by layer through multiple stacked cooling frames 9. At the same time, the first fan 14 installed on the fixed frame 13 starts, and the airflow blows through multiple air outlets on the first air outlet frame 15 to different cooling frames 9, cooling the water inside the cooling frames 9. Finally, the cooled water flowing out from the drain pipe 10 of the bottom cooling frame 9 returns to the fish tank 1.
[0027] like Figures 1-2 As shown, the container also includes a temperature sensor 2, a connecting cable 3, and a display 4. The temperature sensor 2 is located at the bottom of the fish tank 1, and the display 4 is located on the top of the fish tank 1. The connecting cable 3 connects the temperature sensor 2 and the display 4. The temperature sensor 2 is used to detect the temperature of the water in the fish tank 1 in real time. The connecting cable 3 transmits the temperature signal detected by the temperature sensor 2 to the display 4. The display 4 presents the water temperature value to the user intuitively, making it easy to understand the temperature status of the fish tank 1 and determine whether the cooling device needs to be activated.
[0028] like Figures 4-5 As shown, it also includes a first adjusting bolt 12 and a second adjusting bolt 18. The first adjusting bolt 12 is threaded onto the mounting bracket 8, and the second adjusting bolt 18 is threaded onto the fixing bracket 13. The first adjusting bolt 12 and the second adjusting bolt 18 contact and press against the fish tank 1. The first adjusting bolt 12 or the second adjusting bolt 18 is used to fine-tune the clamping force of the mounting bracket 8 or the fixing bracket 13 relative to the fish tank 1, ensuring that the mounting bracket 8 or the fixing bracket 13 is stable and adaptable to different edge thicknesses of the fish tank 1.
[0029] like Figure 5 As shown, it also includes a second fan 16 and a second air outlet frame 17. The second fan 16 is mounted on the fixed frame 13, and the second fan 16 is equipped with the second air outlet frame 17. The second fan 16 and its air outlet frame provide additional air volume, and its air outlet is directed towards the water surface of the fish tank 1, directly accelerating the surface evaporation and heat dissipation of the water in the fish tank 1, and further enhancing the overall cooling effect.
[0030] The cooling frame 9 is equipped with a drain outlet 11, which is located at the lowest point of the water storage area inside the cooling frame 9. The drain outlet 11 is normally closed. When it is necessary to drain the water in the cooling frame 9, the drain outlet 11 can be opened to completely drain the water inside the frame, so as to avoid residual water from breeding bacteria or scaling.
[0031] The drain pipe 10 is located at one corner of the cooling frame 9, and the drain pipes 10 of adjacent cooling frames 9 are located diagonally opposite each other. The bottom of the drain pipe 10 is lower than the top of the adjacent lower drain pipe 10. By deliberately staggering the vertical positions of the upper and lower drain pipes 10, it is ensured that the water flowing out of the upper drain pipe 10 cannot fall directly into the lower drain pipe 10. At the same time, it is ensured that the water is fully cooled in each cooling frame 9 before flowing into the next layer, thereby improving the overall cooling efficiency.
[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
