Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigeration equipment that automatically regulates water temperature. Background Technology

[0002] In the aquaculture industry, refrigeration equipment is a device that lowers the temperature of a specific space or substance. It effectively absorbs and releases heat through the circulation of a refrigerant, achieving the purpose of cooling. Because aquatic animals are extremely sensitive to water temperature, which directly affects their growth rate, reproductive capacity, metabolic level, and even survival rate, maintaining the aquaculture water within a suitable temperature range is crucial for promoting the healthy growth and reproduction of aquatic animals. Refrigeration equipment ensures a stable growth environment for aquatic animals by lowering the temperature of the aquaculture water. Seedling rearing is a key step in aquaculture, requiring a precise and stable water temperature environment to ensure the healthy growth and survival rate of seedlings.

[0003] In conventional refrigeration systems, water pumps are used to draw water from aquatic seedling ponds for temperature control. After passing through the refrigeration unit and cooling, the water is returned to the pond, continuously lowering its temperature. However, because the temperature of the returned water differs significantly from the original pond water, direct discharge into the pond causes excessive temperature fluctuations, negatively impacting aquaculture performance. In severe cases, this can affect the physiological functions of the aquatic seedlings, leading to decreased immunity. Utility Model Content

The buffer tank and the tank body are sequentially mounted on the base. A frame is mounted on the top surface of the tank body. A first hydraulic rod is mounted on the top surface of the frame. The telescopic end of the first hydraulic rod is connected to a support plate. An optical shaft is slidably mounted on the frame. One end of the optical shaft passes through the support plate and the frame and drives a first motor. The first motor is located on the top surface of the support plate.

A second temperature sensor is located inside the buffer tank. The buffer tank is connected to the tank body via an outlet pipe with a flow valve. The bottom of the buffer tank is connected to the bottom of the tank body via an inlet pipe with a second water pump mounted on the inlet pipe. The controller is located on the side of the frame and is electrically connected to the first motor, the first water pump, the second water pump, the first hydraulic rod, the chiller, the flow valve, the first temperature sensor, the second temperature sensor, and the cleaning mechanism.

[0007] Preferably, the cleaning mechanism includes a lifting plate, a vertical plate, a second hydraulic rod, a cylinder, a first rotating shaft, a second motor, brush bristles, and a slider. The lifting plate is located on the side of the optical axis, and a vertical plate is located on its bottom surface. A second hydraulic rod is located on the side of the vertical plate. The telescopic end of the second hydraulic rod is connected to the cylinder. A first rotating shaft is rotatably located inside the cylinder. The first rotating shaft passes through the cylinder and drives the second motor. The second motor is located on the side of the cylinder.

A water suction pipe passes through the sliding groove and is connected to the cylinder. A slider is located at the top of the cylinder, and the slider is slidably connected to the sliding groove.

[0008] Preferably, the filtration mechanism includes a filter tank and a filter screen. The filter tank is located on the side of the water tank, with its opening below the drain pipe. The filter screen is inclinedly disposed inside the filter tank.

[0009] Preferably, the filtration mechanism further includes a collection tank located on the side of the filter tank. The collection tank and the filter tank are provided with a channel, and the lower end of the filter screen passes through the channel and extends into the collection tank.

[0010] Preferably, the filtration mechanism further includes a discharge pipe and a discharge valve, wherein the discharge pipe is located at the bottom of the collection tank and the discharge valve is located on the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A first temperature sensor is installed inside the tank to monitor the water temperature in real time. When the temperature is higher than the preset value, the first water pump draws water out of the tank and cools it through a refrigeration unit.

The flow valve is opened to guide the water in the buffer tank into the buffer tank to mix with the cooling water, reducing the temperature difference between the cooling water and the water in the tank. Then, the second water pump is started to fill the tank with water from the buffer tank. This not only achieves automatic regulation of the water temperature in the tank, but also avoids directly filling the tank with cooling water, which would cause excessive water temperature fluctuations and affect the aquaculture effect.

[0016] 2. A cleaning mechanism is set up. Driven by the first hydraulic rod, the cleaning mechanism can move the water pipe to different positions to collect water. At the same time, the second hydraulic rod can be activated to move the cylinder, so that the bristles come into contact with the inner wall of the tank, thereby cleaning the inner wall of the tank. The wastewater generated during cleaning will be sucked into the cylinder and then pumped out by the first water pump, thus keeping the water in the tank clean.

[0017] 3. A filtration mechanism is installed to filter the water extracted by the cleaning mechanism. After being filtered through an inclined filter screen, the extracted water flows into the chiller through the heat exchange tube. Impurities in the water slide down the inclined filter screen into the collection tank, which facilitates the subsequent treatment of impurities. Attached Figure Description

Detailed Implementation

[0023] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0024] See Figures 1 to 3This utility model provides an automatic water temperature regulating refrigeration device, including a buffer tank 19, a tank body 1, a base 29, a cleaning mechanism, a filtering mechanism, and a controller 20. The tank body 1 is filled with aquaculture water, and fish fry are cultivated in the tank body 1. The buffer tank 19 and the tank body 1 are sequentially arranged on the base 29. A frame 2 is provided on the top surface of the tank body 1. A first hydraulic rod 3 is provided on the top surface of the frame 2. The telescopic end of the first hydraulic rod 3 is connected to a support plate 4. An optical shaft 5 is slidably arranged on the frame 2. One end of the optical shaft 5 passes through the support plate 4 and the frame 2 and is connected to a first motor 6. The first motor 6 is located on the top surface of the support plate 4 and is a stepper motor. The bottom end of the optical shaft 5 is connected to the cleaning mechanism, which is used to clean the inner wall of the tank body 1. A first temperature sensor 23 is provided on the side of the cleaning mechanism. A first water pump 9 is provided on the frame 2. The first water pump 9 is connected to the cleaning mechanism through a water suction pipe 8. The cleaning mechanism is located on the side of the frame 2. The first water pump 9 is connected to the filter mechanism through the drain pipe 10. The bottom of the filter mechanism is connected to the buffer tank 19 through the heat exchange pipe 17. The heat exchange pipe 17 is equipped with a refrigerator 18, which is located on the side of the frame 2. The buffer tank 19 is equipped with a second temperature sensor 31. The buffer tank 19 is connected to the tank body 1 through the water outlet pipe 25. The water outlet pipe 25 is equipped with a flow valve 26. The bottom of the buffer tank 19 is connected to the bottom of the tank body 1 through the water inlet pipe 28. The water inlet pipe 28 is equipped with a second water pump 27. The controller 20 is located on the side of the frame 2 and is electrically connected to the first motor 6, the first water pump 9, the second water pump 27, the first hydraulic rod 3, the refrigerator 18, the flow valve 26, the first temperature sensor 23, the second temperature sensor 31, and the cleaning mechanism. The controller 20 uses a low-power microprocessor of model STM32-L0.

[0025] When the refrigeration unit is working, the first hydraulic rod 3 is activated. The telescopic end of the first hydraulic rod 3 shortens, causing the support plate 4 to descend. The descent of the support plate 4 causes the optical axis 5 to descend, thereby lowering the cleaning mechanism below the water surface in the tank 1. The first temperature sensor 23, located on the side of the cleaning mechanism, detects the water in the tank 1. When the detected water temperature is higher than the set value, the cleaning mechanism and the first water pump 9 are activated. The first water pump 9 extracts the water from the tank 1, while the cleaning mechanism cleans the inner wall of the tank 1 to keep the water clean. The water flows through the suction pipe 8 and the discharge pipe 15 into the filtration mechanism. After being filtered by the filtration mechanism, the water flows through the heat exchange pipe 17 into the refrigeration unit 18. After the water is cooled by the chiller 18, the temperature decreases. The cooling water enters the buffer tank 19 through the heat exchange pipe 17. The controller 20 activates the second temperature sensor 31 to detect the cooling water in the buffer tank 19, and then activates the flow valve 26. The water in the tank 1 flows into the buffer tank 19 from the tank 1. Adjusting the opening of the flow valve 26 can regulate the water temperature in the buffer tank 19. When the water temperature in the buffer tank 19 reaches the target value, the second water pump 27 is activated to fill the tank 1 with water from the buffer tank 19. The water flows into the bottom of the tank 1 through the inlet pipe 28, replenishing the water volume of the tank 1 and slowly lowering the water temperature, stabilizing it at the set water temperature, avoiding excessive water temperature fluctuations, which is beneficial to improving the fry cultivation effect.

[0026] Preferably, the cleaning mechanism includes a lifting plate 7, a vertical plate 32, a second hydraulic rod 33, a cylinder 36, a rotating shaft 22, a second motor 21, brush bristles 37, and a slider 38. The lifting plate 7 is located on the side of the optical axis 5, and the bottom surface of the lifting plate 7 is provided with the vertical plate 32. The side surface of the vertical plate 32 is provided with the second hydraulic rod 33. The telescopic end of the second hydraulic rod 33 is connected to the cylinder 36. The rotating shaft 22 is rotatably provided inside the cylinder 36. The rotating shaft 22 passes through the cylinder 36 and drives the second motor 21. The second motor 21 is located on the side of the cylinder 36. The end of the rotating shaft 22 away from the second motor 21 is provided with brush bristles 37. The lifting plate 7 is provided with a sliding groove 30. The water suction pipe 8 passes through the sliding groove 30 and is connected to the cylinder 36. The top of the cylinder 36 is provided with a slider 38. The slider 38 is slidably connected to the sliding groove 30. The slider 38 and the sliding groove 30 adopt a linear sliding fit to guide the cylinder 36 to move along the direction of the sliding groove 30. The connection method is a conventional technique in this field, and will not be described in detail for the sake of simplifying the accompanying drawings.

[0027] When the refrigeration unit is working, the cleaning mechanism is located below the liquid level inside the tank 1. The second motor 21 is started, and the rotation of the second motor 21 drives the first rotating shaft 22 to rotate, which in turn drives the brush 37 to rotate. Then, the second hydraulic rod 33 is started, and the extension end of the second hydraulic rod 33 extends, causing the cylinder 36 to move, so that the brush 37 comes into contact with the inner wall of the tank 1. The brush 37 cleans the inner wall of the tank 1. Then, the first motor 6 is started, and the rotation of the first motor 6 drives the lifting plate 7 to rotate, and the first hydraulic rod 3 is started, which can drive the brush 37 to move vertically, thereby thoroughly cleaning the inner wall of the tank 1. At the same time, the first water pump 9 is started, and the impurities generated during cleaning are discharged through the water pipe 8 along with the water flow, keeping the water in the tank 1 clean.

[0028] Preferably, the filtration mechanism includes a filter tank 11 and a filter screen 12. The filter tank 11 is located on the side of the water tank, and its opening is located below the drain pipe 10. The filter screen 12 is inclinedly disposed in the filter tank 11.

[0029] The filter tank 11 is located on the side of the pool, and its opening is located below the drain pipe 10. When the water flows out from the drain pipe 10, it first passes through the filter screen 12 in the filter tank 11, thereby intercepting impurities in the water flow. The filter screen 12 is inclined in the filter tank 11, which helps the impurities slide down the filter screen 12 to the lower side of the filter screen 12 under the action of gravity.

[0030] Preferably, the filtration mechanism further includes a collection tank 13, which is located on the side of the filter tank 11. The collection tank 13 and the filter tank 11 are provided with a channel 14, and the lower end of the filter screen 12 passes through the channel 14 and extends into the collection tank 13.

[0031] When water flows from drain pipe 10 into filter tank 11, impurities in the water slide down the inclined filter screen 12 into collection tank 13. The opening of collection tank 13 faces upward, making it easy to observe and clean the impurities in collection tank 13. The design of channel 14 allows the lower end of filter screen 12 to extend into collection tank 13, thereby effectively guiding the impurities trapped during the filtration process to collection tank 13.

[0032] Preferably, the filtration mechanism further includes a discharge pipe 15 and a discharge valve 16, wherein the discharge pipe 15 is located at the bottom of the collection tank 13 and the discharge valve 16 is located on the discharge pipe 15.

[0033] The discharge valve 16 is installed on the discharge pipe 15 to control the discharge of impurities blocked by the filter screen 12. By opening or closing the discharge valve 16, the user can selectively empty the collection tank 13 as needed.

[0034] Preferably, it also includes a second rotating shaft 35, a stirring blade 24, and a third motor 34. The second rotating shaft 35 is rotatably disposed inside the buffer tank 19, the stirring blade 24 is disposed on the second rotating shaft 35, one end of the second rotating shaft 35 passes through the buffer tank 19 and is driven by the third motor 34, and the third motor 34 is disposed on the top surface of the buffer tank 19.

[0035] When the refrigeration unit is working, the water temperature decreases after being cooled by the refrigeration unit 18. The cooling water enters the buffer tank 19 through the heat exchange tube 17. At this time, the third motor 34 is started. The rotation of the third motor 34 drives the second rotating shaft 35 to rotate. The rotation of the second rotating shaft 35 drives the stirring blade 24 to rotate, which is used to mix the cooling water and the water flowing out from the outlet pipe 25 and accelerate heat exchange.

[0036] Preferably, the water pumping pipe 8 is made of polyethylene expansion corrugated pipe.

[0037] When the cleaning mechanism is cleaning, the water pumping pipe 8 moves with the cylinder 36, and the water pumping pipe 8 will deform. The polyethylene expansion corrugated pipe has good expansion performance and can adapt to deformation under different temperatures and pressures.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
