Description

Technical Field

[0001] This utility model belongs to the field of aquaculture insulation technology, specifically relating to aquaculture insulation equipment for fish ponds in winter. Background Technology

[0002] Winter pond insulation measures: I. Water level regulation and fertilization: Water level control: Raise the pond water level to 1.5-2 meters, utilizing the temperature stability of the deeper water area to reduce heat loss and slow down the cooling rate; regularly add fresh water; Fertilization: Cultivate algae through reasonable fertilization to form an fertile pond, utilizing the heat and oxygen generated by algae photosynthesis; II. Physical barrier insulation: Construct greenhouses or windbreaks: Set up windbreaks on the outside of the fishpond to weaken the direct invasion of cold winds; cover with double-layer plastic film to build an A-frame insulated greenhouse, uncovering the straw curtain on sunny days to utilize... Solar heating is used to raise the water temperature, and straw mats are added at night to prevent freezing. Aquatic plants are used to help maintain the temperature: water hyacinths, reeds and other cold-resistant aquatic plants are introduced to form an underwater "haven" where fish can gather to keep warm, while reducing heat loss from the water. Water injection is used to raise the temperature: on sunny afternoons, shallow water that has been heated by the sun is pumped into the fishpond to increase the overall water temperature through mixing. Equipment is used to help: steam heaters, constant temperature heat pumps or intelligent filtration systems (integrating heating and oxygenation functions) are installed to precisely control the water temperature. Aerators or ice breakers are used to keep the water surface flowing to prevent freezing and oxygen deficiency.

[0003] During winter fishpond aquaculture, the low ambient temperature leads to low water temperature in the ponds. Additionally, reduced sunlight intensity and duration significantly decrease the oxygen production capacity of phytoplankton. Furthermore, the stratification of surface cold water with bottom warm water in winter makes it difficult for oxygen to sink, resulting in a decrease in the oxygen content of the pond water. This low oxygen content will affect the growth of fish in the pond. Based on this, we propose equipment for maintaining the temperature of fishponds during winter. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed aquaculture insulation device for fish ponds in winter in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] Winter pond heating equipment includes a base and a fixed rod fixedly connected to the bottom of the base. A sealing ring is fixedly connected to the top of the base, and a rotating cylinder is rotatably connected to the inner surface of the sealing ring. A support rod is fixedly connected to the top of the base, and an air extraction cylinder is fixedly connected to the top of the support rod. The air extraction cylinder extends out of the rotating cylinder and is rotatably connected to it in a sealed manner. An electric heating grid is fixedly connected inside the air extraction cylinder, and an air extraction mechanism is fixedly connected to the air extraction cylinder below the electric heating grid. An air injection pipe is fixedly connected to the outer surface of the rotating cylinder, and an air injection hole is opened at the bottom of the air injection pipe. A drive mechanism is fixedly connected to the inner surface of the rotating cylinder.

[0007] As a further optimization of this utility model, the air extraction mechanism includes a fixed frame fixedly connected to the bottom of the air extraction cylinder, an air extraction motor installed at the bottom of the fixed frame, a rotating shaft fixedly connected to the output end of the air extraction motor, and a fan blade fixedly connected to the top of the rotating shaft. The fan blade is located below the electric heating grid.

[0008] As a further optimization of this utility model, a dustproof net is fixedly connected to the top of the air extraction cylinder, and a cleaning rod is attached to the outer surface of the dustproof net. The cleaning rod is fixedly connected to the top of the rotating cylinder.

[0009] As a further optimization of this utility model, the driving mechanism includes a protective sleeve fixedly connected to the bottom of the base, a rotary motor installed inside the protective sleeve, a transmission gear fixedly connected to the output end of the rotary motor, and a gear ring fixedly connected to the bottom of the inner surface of the rotating drum, the gear ring meshing with the transmission gear.

[0010] As a further optimization of this utility model, the transmission gear is located at the top of the base.

[0011] As a further optimization of this utility model, multiple stirring plates are fixedly connected to the outer surface of the rotating drum, and the multiple stirring plates are arranged in a ring-shaped equidistant array along the central axis of the rotating drum.

[0012] The beneficial effects of this utility model are as follows: By using the drive mechanism, rotating drum, air extraction mechanism, air injection pipe, air injection hole, and stirring plate in combination, when the fishpond is heated, the electric heating net, air extraction mechanism, and drive mechanism work. The air extraction mechanism heats the outside air through the electric heating net and then draws it into the rotating drum, which then enters the air injection pipe and is injected into the fishpond through the air injection hole. During this process, the operation of the drive mechanism causes the rotating drum to rotate, which in turn causes the heated air to mix with the water in the fishpond through the air injection pipe and stirring plate, increasing the oxygen content of the fishpond and ensuring the normal growth of the fish. Furthermore, the rotation of the stirring plate prevents the water surface of the fishpond from freezing, ensuring the circulation of gas in the fishpond and thus improving the heat preservation effect of the fishpond.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the winter pond heating equipment includes a base 1 and a fixed rod 2 fixedly connected to the bottom of the base 1. The fixed rod 2 is designed as an inverted cone shape to facilitate insertion into the bottom of the pond. A sealing ring 3 is fixedly connected to the top of the base 1, and a rotating cylinder 4 is rotatably connected to the inner surface of the sealing ring 3. A support rod 16 is fixedly connected to the top of the base 1, and an air extraction cylinder 5 is fixedly connected to the top of the support rod 16. A dustproof net 6 is fixedly connected to the top of the air extraction cylinder 5. The dustproof net 6 is always positioned above the surface of the pond water and is hemispherical. The air extraction cylinder 5 extends out of the rotating cylinder 4 and is rotatably connected to it. An electric heating net 7 is fixedly connected inside the air extraction cylinder 5, and an air extraction mechanism is fixedly connected inside the air extraction cylinder 5 below the electric heating net 7. The air extraction mechanism includes a fixed connection... A fixed frame 8 is attached to the bottom of the air pump 5. An air pump motor 9 is installed at the bottom of the fixed frame 8. A rotating shaft 10 is fixedly connected to the output end of the air pump motor 9. A fan blade 11 is fixedly connected to the top of the rotating shaft 10. The fan blade 11 is located below the electric heating grid 7. An air injection pipe 12 is fixedly connected to the outer surface of the rotating cylinder 4. The air injection pipe 12 is cylindrical and the end of the air injection pipe 12 is hemispherical. This can reduce the damage to fish in the water when the air injection pipe 12 revolves and reduce the probability of the air injection pipe 12 getting tangled in aquatic plants. A one-way valve is installed inside the air injection pipe 12 so that the gas in the air injection pipe 12 can only be discharged through the air injection hole 13. An air injection hole 13 is opened at the bottom of the air injection pipe 12. The air injection pipe 12 is located at the bottom of the fish pond. A drive mechanism is fixedly connected to the inner surface of the rotating cylinder 4.

[0020] When in use, the electric heating grid 7, the air extraction motor 9, and the drive mechanism are activated. The air extraction motor 9 drives the fan blades 11 through the rotating shaft 10, which in turn causes the air extraction cylinder 5 to draw in outside air through the dustproof net 6. The outside air is filtered by the dustproof net 6 and then heated by the electric heating grid 7. The heated air enters the rotating cylinder 4 and then enters the air injection pipe 12. It is injected into the water body of the fishpond through the air injection hole 13 at the bottom of the air injection pipe 12, thereby heating and keeping the water body of the fishpond warm. This ensures that the water temperature of the fishpond is suitable for fish growth. In addition, the injection of hot air into the water body will increase the oxygen content in the water body, thereby ensuring the normal growth of fish in the fishpond and avoiding oxygen deficiency in the water body, thus ensuring the normal growth of aquatic plants and animals.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the drive mechanism includes a protective sleeve 17 fixedly connected to the bottom of the base 1. A rotary motor 18 is installed inside the protective sleeve 17. A transmission gear 19 is fixedly connected to the output end of the rotary motor 18. A gear ring 20 is fixedly connected to the bottom of the inner surface of the rotating drum 4. The gear ring 20 meshes with the transmission gear 19. The transmission gear 19 is located at the top of the base 1. Multiple stirring plates 14 are fixedly connected to the outer surface of the rotating drum 4. The multiple stirring plates 14 are arranged in a circular equidistant array along the central axis of the rotating drum 4. The multiple stirring plates 14 are all above the upper surface of the water. A cleaning rod 15 is attached to the outer surface of the dustproof net 6. The cleaning rod 15 is fixedly connected to the top of the rotating drum 4.

[0022] When the air injection pipe 12 begins to inject hot air into the water through the air injection hole 13, the rotary motor 18 is started, causing the transmission gear 19 to drive the rotating drum 4 to rotate through the gear ring 20. This, in turn, causes the air injection pipe 12, the cleaning rod 15, and the stirring plate 14 to rotate. The rotation of the air injection pipe 12 will mix the water and hot air, allowing the oxygen in the hot air to dissolve better in the water. In conjunction with the stirring plate 14, it can promote good mixing of the hot air and the water, making the temperature of various parts of the water more uniform and ensuring the normal growth of fish in various parts of the water. Due to the stirring of the water by the stirring plate 14, it can prevent the surface of the water from freezing, ensuring the normal circulation of gas in the fishpond and thus improving the heat preservation effect of the fishpond. The rotation of the cleaning rod 15 will clean the outer surface of the dustproof net 6, preventing the dustproof net 6 from being blocked, which would reduce the efficiency of air intake from the outside and affect the heating and heat preservation efficiency of the water.

[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
