Description

Technical Field

[0001] This utility model relates to the field of giant spiny loach farming technology, and in particular to a reef for giant spiny loach to overwinter. Background Technology

[0002] The giant spiny loach can be found in various river systems south of the Yangtze River and in rivers on Hainan Island in China. However, due to factors such as water quality and overfishing, the wild giant spiny loach population has gradually decreased, so currently, most giant spiny loaches are farmed. While giant spiny loaches can successfully overwinter in the wild, under artificial breeding conditions, except for provinces with higher temperatures such as Hainan, Guangdong, Guangxi, and Fujian where they can safely overwinter, other areas south of the Yangtze River require heating and insulation measures to ensure their safe overwintering. For example, when temperatures are low, heating plates or heating rods can be installed in the breeding ponds to raise the water temperature. Artificial breeding requires the water temperature not to fall below 15℃. Existing heating plates or heating rods mainly use electric heating, which poses a risk of electric leakage when immersed in water for a long time. At the same time, heating the entire breeding pond requires a large amount of electricity. Therefore, there is a need for a reef for the overwintering of spiny loaches. This reef takes advantage of the fact that spiny loaches like to inhabit tubular burrows. By setting heating units in the reef, the water temperature inside and around the reef is increased. The heating units use air source heat pump water heaters, which have high thermal efficiency, reduce electricity consumption, and eliminate concerns about electric leakage, thus meeting the needs of spiny loaches for safe overwintering. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a reef for overwintering giant spiny loach. Utilizing the loach's preference for inhabiting tubular burrows, a heating unit is installed within the reef to raise the water temperature inside and around it. The heating unit employs an air-source heat pump, which boasts high thermal efficiency, reduces energy consumption, eliminates concerns about electrical leakage, and meets the needs of giant spiny loach for safe overwintering.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a reef for overwintering giant spiny loach, comprising: a first reef tube, a second reef tube, a connecting plate, and a heating tube. The first and second reef tubes are parallel to each other, and their ends and middle are connected to each other by the connecting plate. The heating tube is installed on the inner wall of the first and second reef tubes along their length, and the inlet and outlet of the two heating tubes are connected to each other by the connecting tube. The first and second reef tubes are installed at the bottom of the aquaculture pond by the connecting plate.

[0006] Furthermore, the heating tube is installed in the first and second reef tubes in an S-shaped reciprocating bend, and heat-conducting fins are installed at intervals in the middle of the heating tube. The heating tube is connected to the inner wall of the first and second reef tubes through the heat-conducting fins.

[0007] Furthermore, it also includes an air source water heater and a water tank. The lower part of the water tank is connected to the inlet of the air source water heater via a circulation pump. The outlet of the air source water heater is connected to a connecting pipe on the side of the inlet of the heating element. The connecting pipe on the side of the outlet of the heating element is connected to the upper part of the water tank.

[0008] Furthermore, the water tank is equipped with a water supply pipe, which is connected to the water tank via a float valve.

[0009] Furthermore, there are multiple sets of the first and second artificial reef pipes, and each set of the first and second artificial reef pipes is equipped with a heating pipe. The multiple heating pipes are connected to the air source water heater and the water tank in parallel.

[0011] Furthermore, the lower parts of the first and second reef pipes are 20cm to 40cm away from the bottom of the connecting plate.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0019] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, one embodiment of this utility model provides a reef for overwintering giant spiny loach, comprising: a first reef pipe 1, a second reef pipe 2, a connecting plate 3, and a heating pipe 4. The first reef pipe 1 and the second reef pipe 2 are parallel to each other, and their ends and middle are connected to each other through the connecting plate 3. The heating pipe 4 is installed on the inner wall of the first reef pipe 1 and the second reef pipe 2 along the length direction of the first reef pipe 1 and the second reef pipe 2, and the inlet and outlet of the two heating pipes 4 are connected to each other through the connecting pipe 5. The first reef pipe 1 and the second reef pipe 2 are installed at the bottom of the breeding pond through the connecting plate 3.

[0021] The first reef pipe 1 and the second reef pipe 2 utilize the characteristic that the spiny loach prefers to inhabit tubular burrows. By introducing hot water at 35°C to 50°C into the heating pipe 4, the water inside the first reef pipe 1 and the second reef pipe 2, as well as the water at the bottom of the breeding pond, can be heated to meet the requirement of a water temperature above 15°C for the spiny loach during overwintering. The heating pipe 4 uses hot water for heating, which results in a lower temperature and avoids scalding the spiny loach. Multiple heating pipes 4 can be installed at the bottom of the breeding pond to increase the heating area and ensure heating efficiency. The hot water heating method avoids the direct immersion of electrical wires in the pond water, reducing the risk of electric leakage.

[0022] Preferably, such as Figure 2 As shown, the heating tube 4 is installed in the first reef tube 1 and the second reef tube 2 in an S-shaped reciprocating bend, and heat-conducting fins 6 are installed at intervals in the middle of the heating tube 4. The heating tube 4 is connected to the inner wall of the first reef tube 1 and the second reef tube 2 through the heat-conducting fins 6. The S-shaped heating tube 4 can increase the flow path of hot water and improve the heating effect. In addition to fixing the heating tube 4, the heat-conducting fins 6 can also increase the heat conduction area and improve the heating efficiency.

[0023] Specifically, such as Figure 3 As shown, it also includes an air source water heater 7 and a water tank 8. The lower part of the water tank 8 is connected to the inlet of the air source water heater 7 via a circulation pump 9. The outlet of the air source water heater 7 is connected to a connecting pipe 5 on the inlet side of the heating element 4, and the connecting pipe 5 on the outlet side of the heating element 4 is connected to the upper part of the water tank 8. The air source water heater 7 uses commercially available air source water heaters. The air source water heater uses components such as a compressor, evaporator, and condenser to evaporate the refrigerant, absorb heat, and then liquefy and release heat in the condenser. This heat is used to heat the circulating water, thereby raising the temperature of the circulating water. Compared with the heating method of electric heating elements, the overall energy consumption of the air source water heater 7 can be reduced by 40% to 60%, which can reduce the power consumption when heating the pool water. Moreover, heat transfer through circulating water can avoid the wires being directly immersed in the pool water, reducing the risk of electric leakage.

[0024] In a specific embodiment, such as Figure 3 As shown, the water tank 8 is equipped with a water supply pipe 10, which is connected to the water tank 8 through a float valve 11. When the circulation pipeline may experience minor leaks due to aging or other reasons, resulting in water loss, the water supply pipe 10 can be used to replenish the circulation water in the water tank 8 to ensure the normal operation of the heating element 4.

[0025] In a preferred embodiment, such as Figure 3As shown, there are multiple sets of the first reef pipe 1 and the second reef pipe 2, which facilitates the habitat of fish. Each set of the first reef pipe 1 and the second reef pipe 2 is equipped with a heating pipe 4. The multiple heating pipes 4 are connected to the air source water heater 7 and the water tank 8 in parallel. The multiple sets of heating pipes 4 can increase the heat conduction area, thereby improving the heating efficiency.

[0026] In a preferred embodiment, the connecting pipe 5 is provided with external threads, and a sealing ring is provided at the pipe opening of the connecting pipe 5, so as to facilitate connection with the air source water heater 7 or the water tank 8 through the threads, which facilitates connection and improves airtightness.

[0027] In a preferred embodiment, the lower parts of the first reef pipe 1 and the second reef pipe 2 are 20cm to 40cm away from the bottom of the connecting plate 3, so that the first reef pipe 1 and the second reef pipe 2 are far away from the bottom of the pool, reducing the deposition of silt in the first reef pipe 1 and the second reef pipe 2 after being stirred up at the bottom of the pool.

[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
