Abstract
Description
A tilapia overwintering device Technical Field
[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a tilapia overwintering hotbed device. Background Technology
[0002] Tilapia is a FAO-recommended farmed fish species worldwide, with major production areas including Guangdong, Hainan, Guangxi, Yunnan, and Fujian. Tilapia has no intramuscular bones, delicious flesh, and an affordable price, making it popular with many. As a tropical fish, tilapia requires water temperatures no lower than 14°C in winter, necessitating heating during cold seasons. Currently, common heating methods include using plastic greenhouses combined with boilers, electricity, and waste heat from electric fields to directly heat the pond water. Additionally, there is the practice of using heating island technology to heat specific areas of the pond. All heating methods target the pond water; however, due to the large volume of water in overwintering ponds, significant heat loss occurs, requiring substantial energy consumption to maintain a safe water temperature.
[0003] Therefore, there is an urgent need for an energy-efficient tilapia overwintering device. Summary of the Invention
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a tilapia overwintering device that ensures tilapia can overwinter while significantly saving energy.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The purpose of this invention is to provide a tilapia overwintering hotbed device to solve the problems existing in the prior art. By setting up a heater and a hotbed, the heater provides hot water to the hotbed, raising the temperature of the hotbed and causing tilapia to concentrate on the hotbed for overwintering. Compared with directly heating the water in the overwintering pond, the amount of water that needs to be heated is greatly reduced. Moreover, there is only heat exchange between the hotbed and the water in the overwintering pond, without water flow exchange, which allows the water in the hotbed to maintain a higher temperature for a longer period of time, further reducing energy consumption.
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] As shown in Figures 1 and 2, this embodiment provides a tilapia overwintering device, including a heater 1 and a hotbed 6; the heater 1 is used to provide hot water to the hotbed 6; the hotbed 6 is located at the bottom of the overwintering pond 3.
[0027] The bottom area of the hotbed 6 and the overwintering pond 3 can be equal or smaller. The specific size can be determined based on the number of tilapia raised in the overwintering pond 3, ensuring that all tilapia in the overwintering pond 3 can overwinter on the hotbed 6.
[0028] The hot water generated in heater 1 is supplied into the hotbed 6 to raise the water temperature in the hotbed 6, thereby creating a suitable water temperature environment for tilapia to overwinter around the hotbed 6, especially above the hotbed 6. This allows the tilapia to overwinter in a concentrated manner, reducing the energy consumption required to heat the water in the entire overwintering pond 3. While ensuring the safe overwintering of tilapia, energy consumption is reduced by more than 40%.
[0029] In some more specific embodiments, the heater 1 is provided with a heating element for heating the water inside the heater 1. The heating element can specifically be a heating plate 2, and in other specific embodiments, the heating element can also be an electric heating tube.
[0030] In some more specific embodiments, the lower part of the heater 1 is connected to the hotbed 6 via a water inlet pipe 7, and a water pump 8 is installed on the water inlet pipe 7. Hot water in the heater 1 enters the hotbed 6 through the water pump 8 and the water inlet pipe 7. The water source for the heater 1 can be the water from the overwintering pool 3, or it can be fresh water, such as groundwater or tap water.
[0031] In some more specific embodiments, the hotbed 6 includes a bed body, which comprises a mesh, a sealing surface, and a fixing plate. The sealing surface is disposed around the mesh, and the fixing plate is disposed below the sealing surface on the bottom surface of the mesh. The fixing plate is used to fix the bed body to the bottom of the overwintering pool 3. The fixing plate is a suction cup disposed at the bottom of the bed body, used to adhere the bed body to the bottom of the overwintering pool 3 and prevent the bed body from moving due to water flow. The sealing surface can be made of a waterproof film material, such as a plastic film.
[0032] In some more specific embodiments, the mesh includes an upper bottom surface, a lower bottom surface, and a side surface; the upper bottom surface is located above the side surface, and the lower bottom surface is located below the side surface. Multiple fixing lines are provided between the upper and lower bottom surfaces, and the length of each fixing line is equal to the height of the side surface. These fixing lines prevent deformation when the bed is overfilled with water, maintaining the bed's rectangular structure and avoiding localized damage after deformation.
[0033] In some more specific embodiments, a drain pipe 5 is provided on the side of the bed away from the water inlet pipe 7, and the drain pipe 5 is connected to the overwintering pool 3. A temperature controller 10 is provided in the bed at the water inlet end of the drain pipe 5, and the temperature controller 10 is connected to the water pump 8. When the water temperature in the warm bed 6 is too low, the heater 1 will replenish the warm bed 6 with hot water, and at the same time, cool water will be discharged from the drain pipe 5. When the temperature controller 10 detects that the water temperature is too high, the water pump 8 will stop supplying water to the warm bed 6 to prevent the water temperature from becoming too high.
[0034] In some more specific embodiments, a check valve is provided on the drain pipe 5 to prevent water in the overwintering pool 3 from flowing into the bed.
[0035] To ensure unobstructed drainage in overwintering pond 3, the hotbed 6 does not cover the drainage hole 4 of overwintering pond 3.
[0036] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model.
