Description

Technical Field

[0001] This utility model relates to the field of abalone farming technology, and in particular to a device for precise control and constant temperature maintenance of abalone farming pond water. Background Technology

[0002] As a high-value-added aquaculture species, abalone has extremely strict requirements for the water temperature conditions of its growth environment. The suitable water temperature range is narrow and needs to be kept stable. Water temperatures that are too high or too low will lead to reduced feeding, stunted growth, and even disease. Furthermore, problems such as local water temperature stratification and temperature fluctuations in the aquaculture pond will seriously affect the survival rate and quality of abalone. Therefore, water temperature control is a core technical aspect of abalone farming.

[0003] Traditional abalone farming methods for water temperature control have many limitations: Firstly, most rely on electronic sensors to monitor water temperature, which are easily affected by the humid environment of the farming water, leading to signal delays or distortions and making it difficult to quickly capture subtle changes in water temperature. Furthermore, the failure rate of electronic components is relatively high, requiring frequent maintenance. In addition, the water circulation and water temperature diffusion design of traditional farming ponds are unreasonable, causing heated water to tend to accumulate in local areas and fail to spread quickly and evenly throughout the entire farming pond, resulting in obvious water stratification. Static or localized water circulation not only reduces heat transfer efficiency but also causes differences in abalone growth due to uneven water temperature distribution. At the same time, insufficient water flow also leads to low dissolved oxygen levels, further affecting the farming ecological environment.

[0004] Therefore, in order to address the existing problems in abalone farming, there is an urgent need to develop a device for precise temperature control and constant temperature maintenance in abalone farming ponds. Utility Model Content

[0005] To overcome the technical defects of existing technologies, this utility model provides a device for precise temperature control and constant temperature maintenance in abalone farming ponds. It can quickly capture subtle changes in water temperature without the need for signal conversion processes using electronic components, thus avoiding the delays or signal distortion problems that may exist in electronic sensing. It enables real-time perception and feedback of water temperature changes, allowing hot water to quickly diffuse to all areas of the farming pond. The stirring blades continuously agitate the water in the farming pond, breaking up the static stratification of the water and ensuring that the temperature-controlled hot water is fully mixed with the original water in the pond, accelerating heat transfer efficiency and ensuring that the water temperature in the farming pond remains stable within the range suitable for abalone growth, providing a stable water temperature environment and uniform water temperature.

[0006] The technical solution adopted in this utility model is: a device for precise temperature control and constant temperature maintenance in abalone farming ponds, including a farming pond body. A temperature regulating pond body is fixed to one side of the farming pond body for regulating the temperature of the water in the farming pond body. The top of the temperature regulating pond body is connected to the top of the farming pond body. A heating rod is fixed inside the temperature regulating pond body for heating the water in the temperature regulating pond body. A water pump is fixed at the bottom of the temperature regulating pond body for driving the water to circulate between the farming pond body and the temperature regulating pond body. A fixing frame is fixed to the surface of the farming pond body. A temperature sensing cylinder is fixed to the surface of the fixing frame. The temperature sensing cylinder contains a gas that expands easily when heated and extends below the water in the farming pond body. Multiple sets of stirring blades are arranged inside the farming pond body. A drain pipe is fixed to the side of the farming pond body near the stirring blades. The farming pond body and the temperature regulating pond body are the core carriers for water temperature control. The tops of the two are connected to form a circulation base. The heating rod in the temperature regulating pond body provides a heat source for water temperature regulation, and the water pump at the bottom provides power for water circulation.

[0007] Preferably, the input end of the water pump is fixed with a pumping pipe, the other end of which is connected to the temperature regulating tank. The output end of the water pump is fixed with an outlet pipe, the other end of which is connected to the aquaculture tank. When the water pump is started, water in the temperature regulating tank is drawn into the aquaculture tank. As the water level in the aquaculture tank increases and exceeds the height of the connection between the top of the temperature regulating tank and the top of the aquaculture tank, the water in the aquaculture tank will automatically flow back into the temperature regulating tank to achieve circulation. After the water pump is started, the water in the temperature regulating tank enters the water pump through the pumping pipe and is transported to the aquaculture tank through the outlet pipe. When the water level in the aquaculture tank exceeds the height of the connection between the tops of the two tanks, the water automatically flows back into the temperature regulating tank, forming a water circulation path to ensure that the water temperature regulation can cover the entire aquaculture water body.

[0008] Preferably, a rocker arm is hinged to the surface of the fixed frame, and a push rod is slidably connected inside the temperature-sensing gas cylinder. The end of the push rod is hinged to the rocker arm. The temperature-sensing gas cylinder contains a gas that expands easily when heated. When the water temperature rises, the gas expands and pushes the internal push rod to extend. When the water temperature drops, the gas contracts and drives the push rod to retract. The end of the push rod is connected to the rocker arm hinged to the fixed frame. The extension and retraction of the push rod is converted into the swinging motion of the rocker arm.

[0009] Preferably, the surface of the temperature-sensing air cylinder is fixed with several sets of temperature-sensing fins arranged at equal intervals. The temperature-sensing fins are used to sense the water temperature. When the water temperature changes, the change is transmitted to the temperature-sensing air cylinder, causing the gas inside the temperature-sensing air cylinder to expand or contract, which drives the swing arm to swing. The temperature-sensing air cylinder extends into the water of the aquaculture pond. The several sets of temperature-sensing fins arranged at equal intervals on its surface increase the contact area with the water, which can quickly sense changes in water temperature and transfer heat to the inside of the temperature-sensing air cylinder.

[0010] Preferably, a movable frame is attached to the end of the swing arm away from the temperature-sensing air cylinder. The movable frame is slidably connected to a movable groove inside the fixed frame. An electronic terminal is fixed on the surface of the fixed frame, and a female terminal compatible with the electronic terminal is fixed inside the movable frame. When the water temperature reaches the boundary of the set range, the female terminal contacts or separates from the electronic terminal to control the on / off state of the heating rod. The two work together to form a control switch for the heating device. The movable frame is attached to the end of the swing arm away from the temperature-sensing air cylinder. The movable frame slides within the movable groove of the fixed frame as the swing arm swings. The female terminal inside the movable frame and the electronic terminal on the surface of the fixed frame form a control switch assembly.

[0011] Preferably, the aquaculture tank has a fixed annular conveying pipe inside, which is connected to an outlet pipe for supplying water to the conveying pipe. Several sets of inlet pipes are fixed on the surface of the conveying pipe, and a water-rotating seat is connected to the end of the inlet pipe. The water-rotating seat is fixed to the bottom of the aquaculture tank. A rotating shaft is rotatably connected inside the water-rotating seat, and an impeller is installed inside the water-rotating seat. The impeller is fixedly connected to the rotating shaft. The water flow impacts the impeller, causing the rotating shaft to rotate. The stirring blade is fixed to the top of the rotating shaft to stir the water in the aquaculture tank, making the water temperature uniform. When the water temperature is lower than the set lower limit, the gas in the temperature-sensing cylinder contracts, the swing arm swings, and the moving frame slides, so that the power connection terminal contacts the electronic connection terminal. The heating rod is powered on and starts heating. When the water temperature reaches the set upper limit, the gas expands, pushing the swing arm to swing in the opposite direction. The power connection terminal separates from the electronic connection terminal, the heating rod is powered off and stops heating, realizing automatic start and stop regulation of water temperature.

[0012] Preferably, the end of the drain pipe is connected to the surface of the water-turning seat to drain the water inside the water-turning seat. The drain pipe and the inlet pipe are arranged symmetrically about the water-turning seat. A protective cover is provided above the stirring blade. The protective cover is fixed to the bottom of the aquaculture tank. The surface of the protective cover is provided with water passage holes to protect the stirring blade without affecting the flow and heat exchange of water. The annular conveying pipe inside the aquaculture tank is connected to the outlet pipe. The temperature-adjusted water flows through the conveying pipe to each group of inlet pipes and impacts the impeller inside the water-turning seat. The impeller is fixedly connected to the rotating shaft. The impact force of the water flow drives the impeller to rotate, thereby causing the rotating shaft to rotate synchronously. The stirring blade at the top of the rotating shaft rotates with the rotating shaft to stir the water in the aquaculture tank. The drain pipe and the inlet pipe on the surface of the water-turning seat are arranged symmetrically to ensure uniform water flow. Combined with the stirring action of the stirring blade, the water temperature in the aquaculture tank is eliminated, and the overall water temperature remains consistent.

[0013] Preferably, the abalone farming pond water temperature precise control and constant temperature maintenance device described in any one of the claims is used. The farming pond body is equipped with heat-insulating pipes that are distributed in a serpentine pattern to reduce heat loss from the water in the farming pond body and help maintain a constant water temperature. The heat-insulating pipes distributed in a serpentine pattern inside the farming pond body reduce heat exchange between the farming pond body and the external environment, reduce the natural heat dissipation rate of the water body, help maintain a constant water temperature after heating, reduce the frequency of heating rod start-stop, and save energy.

[0014] The beneficial effects of this invention are: it can quickly capture subtle changes in water temperature. The temperature-sensing cylinder uses a gas that expands easily when heated as the sensing medium. When the water temperature changes, the gas can expand or contract instantly, directly driving the swing arm to move via the push rod. There is no need for signal conversion by electronic components, avoiding the delay or signal distortion problems that may exist in electronic sensing. It realizes real-time perception and feedback of water temperature changes, ensuring that the heating energy in the temperature-regulating tank can be transferred to every part of the aquaculture tank through water circulation, avoiding the problem of local water temperature not being regulated, and realizing synchronous regulation of water temperature throughout the entire area. The whole process does not require manual monitoring or adjustment, realizing fully automatic regulation of water temperature, reducing the operation difficulty and labor intensity of aquaculture personnel.

[0015] It enables hot water to quickly spread to all areas of the aquaculture pond. The stirring blades continuously agitate the water, breaking up static stratification and allowing the regulated hot water to fully mix with the existing water in the pond. This accelerates heat transfer efficiency and ensures that the water temperature in the aquaculture pond remains stable within the range suitable for abalone growth. The stable and uniform water temperature provides suitable growth conditions for abalone, reducing stress caused by water temperature fluctuations and lowering the risk of disease. At the same time, the circulating and agitating water not only optimizes the water temperature distribution but also enhances water flow, increases dissolved oxygen levels, and improves the ecological environment of the aquaculture pond. This indirectly promotes abalone feeding and growth, increasing survival rate and yield. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings: As shown in the figure, this embodiment provides a device for precise temperature control and constant temperature maintenance of abalone farming pond water, including a farming pond 1. A temperature regulating pond 2 is fixed to one side of the farming pond 1 for regulating the temperature of the water in the farming pond 1. The top of the temperature regulating pond 2 is connected to the top of the farming pond 1. A heating rod 3 is fixed inside the temperature regulating pond 2 for heating the water in the temperature regulating pond 2. A water pump 4 is fixed to the bottom of the temperature regulating pond 2 for driving the water to circulate between the farming pond 1 and the temperature regulating pond 2. A fixing frame 7 is fixed to the surface of the farming pond 1. A temperature sensing cylinder 9 is fixed to the surface of the fixing frame 7. The temperature sensing cylinder 9 contains a gas that expands easily when heated and extends into the water inside the farming pond 1. Multiple sets of stirring blades 19 are arranged inside the farming pond 1. A drain pipe 20 is fixed to the side of the farming pond 1 near the stirring blades 19.

[0025] The input end of the water pump 4 is fixed with a water suction pipe 5, and the other end of the water suction pipe 5 is connected to the temperature regulating tank 2. The output end of the water pump 4 is fixed with a water outlet pipe 6, and the other end of the water outlet pipe 6 is connected to the aquaculture tank 1. When the water pump 4 is started, the water in the temperature regulating tank 2 can be drawn into the aquaculture tank 1. As the water in the aquaculture tank 1 increases, after exceeding the height of the connection between the top of the temperature regulating tank 2 and the top of the aquaculture tank 1, the water in the aquaculture tank 1 will automatically flow back into the temperature regulating tank 2 to achieve circulation.

[0026] A rocker arm 8 is hinged to the surface of the fixed frame 7, and a push rod is slidably connected inside the temperature sensing cylinder 9, with the end of the push rod hinged to the rocker arm 8.

[0027] Several sets of temperature-sensing fins 10 are fixed on the surface of the temperature-sensing cylinder 9. The temperature-sensing fins 10 are used to sense the water temperature. When the water temperature changes, it is transmitted to the temperature-sensing cylinder 9, causing the gas inside the temperature-sensing cylinder 9 to expand or contract, which in turn drives the swing arm 8 to swing.

[0028] A movable frame 11 is hung on the end of the swing arm 8 away from the temperature sensing cylinder 9. The movable frame 11 is slidably connected to the movable groove opened inside the fixed frame 7. An electronic terminal 13 is fixed on the surface of the fixed frame 7. An electrical female terminal 12 that is compatible with the electronic terminal 13 is fixed inside the movable frame 11. When the water temperature reaches the boundary of the set range, the electrical female terminal 12 contacts or separates from the electronic terminal 13 to control the on / off of the heating rod 3. The two work together to form the control switch of the heating device.

[0029] An annular conveying pipe 14 is fixed inside the aquaculture tank 1, and the conveying pipe 14 is connected to the outlet pipe 6 for supplying water into the conveying pipe 14. Several sets of inlet pipes 15 are fixed on the surface of the conveying pipe 14. A water rotating seat 16 is connected to the end of the inlet pipe 15, and the water rotating seat 16 is fixed to the bottom of the aquaculture tank 1. A rotating shaft 17 is rotatably connected inside the water rotating seat 16. An impeller 18 is set inside the water rotating seat 16, and the impeller 18 is fixedly connected to the rotating shaft 17. The water flow impacts the impeller 18, which drives the rotating shaft 17 to rotate. A stirring blade 19 is fixed to the top of the rotating shaft 17 for stirring the water in the aquaculture tank 1 to make the water temperature uniform.

[0030] The end of the drain pipe 20 is connected to the surface of the water-turning seat 16 to drain the water in the water-turning seat 16. The drain pipe 20 and the water inlet pipe 15 are arranged symmetrically about the water-turning seat 16. A protective cover 21 is provided above the stirring blade 19. The protective cover 21 is fixed to the bottom of the aquaculture tank 1. The surface of the protective cover 21 is provided with water passage holes to protect the stirring blade 19 without affecting the flow of water and heat exchange.

[0031] Any one of the following abalone farming pond water temperature precise control and constant temperature maintenance devices is adopted. The inside of the farming pond 1 is equipped with heat preservation pipes 22, which are distributed in a serpentine pattern to reduce heat loss of the water in the farming pond 1 and help maintain a constant water temperature.

[0032] The working principle and usage process of this utility model are as follows: During use, the aquaculture tank 1 and the temperature-regulating tank 2 serve as the core carriers for water temperature control. Their tops are connected to form a circulation system. The heating rod 3 inside the temperature-regulating tank 2 provides the heat source for water temperature regulation, and the water pump 4 at the bottom provides the power for water circulation. After starting the water pump 4, water from the temperature-regulating tank 2 enters the water pump 4 through the pump pipe 5 and is then transported to the aquaculture tank 1 through the outlet pipe 6. When the water level in the aquaculture tank 1 exceeds the height connecting the tops of the two tanks, the water automatically flows back to the temperature-regulating tank 2, forming a water circulation path. This ensures that water temperature regulation can cover the entire aquaculture water body. The temperature-sensing air cylinder 9 extends into the water body of the aquaculture tank 1, and several sets of equidistantly arranged air cylinders on its surface... The temperature-sensing fin 10 increases the contact area with water, enabling it to quickly sense changes in water temperature and transfer heat to the inside of the temperature-sensing cylinder 9. The temperature-sensing cylinder 9 contains a gas that expands easily when heated. When the water temperature rises, the gas expands and pushes the internal push rod out. When the water temperature drops, the gas contracts and drives the push rod back. The end of the push rod is connected to a rocker arm 8 hinged to the fixed frame 7. The extension and retraction of the push rod is converted into the swinging motion of the rocker arm 8. A movable frame 11 is hung at the end of the rocker arm 8 away from the temperature-sensing cylinder 9. The movable frame 11 slides in the movable groove of the fixed frame 7 as the rocker arm 8 swings. The electrical terminal 12 inside the movable frame 11 and the electronic terminal 13 on the surface of the fixed frame 7 form a control switch assembly.

[0033] Furthermore, when the water temperature is below the set lower limit, the gas inside the temperature-sensing cylinder 9 contracts, the swing arm 8 swings, and the moving frame 11 slides, causing the power connector 12 to contact the electronic connector 13. The heating rod 3 is then energized and starts heating. When the water temperature reaches the set upper limit, the gas expands, pushing the swing arm 8 to swing in the opposite direction. The power connector 12 separates from the electronic connector 13, and the heating rod 3 is de-energized and stops heating, thus achieving automatic start-stop regulation of the water temperature. The annular conveying pipe 14 inside the aquaculture tank 1 is connected to the outlet pipe 6, and the regulated water flows through the conveying pipe 14 for diversion. The water flows into each group of inlet pipes 15 and impacts the impeller 18 inside the rotating base 16. The impeller 18 is fixedly connected to the rotating shaft 17. The impact force of the water flow drives the impeller 18 to rotate, thereby causing the rotating shaft 17 to rotate synchronously. The stirring blade 19 at the top of the rotating shaft 17 rotates with the rotating shaft 17, stirring the water in the aquaculture tank 1. The drain pipe 20 on the surface of the rotating base 16 is arranged symmetrically with the inlet pipe 15 to ensure uniform water flow. Combined with the stirring action of the stirring blade 19, it eliminates water temperature stratification in the aquaculture tank and keeps the overall water temperature consistent.

[0034] It should be noted that the protective cover 21 above the stirring blade 19 is fixed to the bottom of the aquaculture tank 1. The water passage holes on its surface not only prevent abalone and other farmed organisms from coming into contact with the stirring blade 19 and causing damage, but also do not obstruct water flow and heat exchange. The stirring power comes from the impact force of the natural water flow of the water circulation, without the need for an additional motor drive, thus saving energy while achieving uniform water temperature.

[0035] Furthermore, the aquaculture pond 1 is equipped with serpentine heat-insulating pipes 22, which reduce the heat exchange between the aquaculture pond 1 and the external environment, reduce the natural heat dissipation rate of the water, help maintain a constant water temperature after heating, reduce the frequency of starting and stopping the heating rod 3, and save energy.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of the invention. All such changes and modifications fall within the scope of the invention as claimed, which is defined by the appended claims and their equivalents.
