Description

Technical Field

[0001] This application relates to the field of aquaculture technology, and in particular to a temperature control device for off-season bass seedling raising. Background Technology

[0002] The California bass, also known as the black bass, belongs to the order Perciformes and the family Sunfish. It is an economically important freshwater fish that grows quickly, has delicious flesh, and high nutritional value. In the domestic market, California bass has always maintained a high demand, especially in the northern regions. Due to local farming restrictions, most of the California bass sold in the market are transported from the south. This not only leads to higher prices, but also causes the supply to fluctuate greatly due to seasonal changes, making it difficult to meet consumer demand.

[0003] California bass can survive in water temperatures ranging from 1 to 36°C. Their temperature adaptability is similar to that of carp, but they have a wider salinity tolerance range, making them suitable for aquaculture in most parts of my country. However, in areas north of the Yangtze River, spring water temperatures are too low to meet the breeding requirements of California bass. Locally bred fry typically cannot be released until after April. Even fry purchased from the south need to arrive in March and be temporarily held indoors until the outdoor water temperature rises to around 15°C before being released into ponds. Furthermore, the effective growth temperature for California bass (above 20°C) only lasts for about three months, meaning that fry (generally around 3cm) released into ponds often fail to reach marketable size in the same year. After overwintering, high mortality rates due to saprolegniasis in the spring lead to frequent losses in aquaculture. If larger fry are released in the spring, they can be marketed by September, coinciding with peak market prices, significantly increasing the profitability of California bass farming.

[0004] A search revealed a Chinese patent application (patent number 202210703253.X) disclosing a method for cultivating California bass to reach gonadal maturity twice a year. This method includes steps such as selecting and temporarily holding broodstock, lowering the culture water temperature in summer, raising the culture water temperature in autumn and winter, adjusting light duration, regulating broodstock nutrition, and calculating the gonadal maturity index. These measures induce California bass to mature their gonads out of season to meet the severe demand for broodstock in off-season breeding. However, the method described in the patent requires lowering the water temperature in the breeding pond to 12-15℃ at a rate of 0.5-1.5℃ per day in summer, a process that takes 10-13 days. This operation is entirely manual, consuming a large amount of manpower, and the broodstock are prone to stress reactions due to temperature changes. Furthermore, well water usually contains large amounts of nitrogen and carbon dioxide, and direct addition may lead to gas bubble disease. Therefore, we propose a temperature control device for off-season breeding of California bass to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a temperature control device for off-season sea bass fry breeding to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A temperature control device for off-season bass fry rearing includes a water storage tank and a fish pond located on one side of the water storage tank.

[0016] This application, through its automatic water storage structure and water treatment components, can automatically extract low-temperature groundwater into a storage tank and aerate the extracted groundwater to accelerate the release of nitrogen and carbon dioxide, effectively preventing sea bass from developing gas bubble disease. The automatic water supply structure monitors the water temperature inside the fishpond; if the temperature becomes too high, it automatically injects low-temperature groundwater into the fishpond, lowering the water temperature to a suitable range for sea bass growth. This gentle temperature adjustment method avoids drastic temperature changes, allowing the sea bass to gradually adapt and preventing stress reactions caused by sudden temperature drops.

[0017] With its automatic drainage and sewage discharge structure, when low-temperature groundwater is injected into the fish pond, the high-temperature water inside the pond can be automatically discharged. At the same time, impurities and feces deposited at the bottom of the fish pond can be discharged from the sewage outlet with the water flow at regular intervals, effectively maintaining the cleanliness of the water in the fish pond, providing a good growth environment for the bass and promoting their healthy growth.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] 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.

[0025] Please see Figure 1-4 In this utility model, a temperature control device for off-season bass fry rearing includes a water storage tank 1 and a fish pond 2 set on one side of the water storage tank 1. The bottom of the water storage tank 1 is level with the fish pond 2, and the water level inside the water storage tank 1 is higher than the water temperature inside the fish pond 2. Two positioning plates 15 are fixedly connected to the outer surface of the water storage tank 1. The other end of each positioning plate 15 is connected to the outer surface of the fish pond 2. The positioning plates 15 can be used to connect the water storage tank 1 and the fish pond 2, ensuring that the bottoms of the water storage tank 1 and the fish pond 2 are level, and ensuring that there is a water pressure difference between the water storage tank 1 and the fish pond 2.

[0026] A controller 16 is installed on the outer surface of the reservoir 1. The reservoir 1 is equipped with an automatic water storage structure for pumping groundwater into the reservoir 1 to maintain its water level. The automatic water storage structure includes a level sensor 3 installed inside the reservoir 1 and a submersible pump 4 located on one side of the reservoir 1. The output end of the submersible pump 4 is connected to a water storage pipe 5, and the output end of the water storage pipe 5 is located above the reservoir 1. When the level sensor 3 detects that the water level inside the reservoir 1 is lower than the preset minimum water level value, it will immediately send a signal to the controller 16, and the controller 16 will control the submersible pump 4 to work. It can extract groundwater into the reservoir 1. As the water level in the reservoir 1 rises, when the level sensor 3 detects that the water level has reached the set maximum level, it will promptly transmit the signal to the controller 16. At this time, the controller 16 will control the submersible pump 4 to stop working, thereby preventing the reservoir 1 from overflowing due to excessive water level. A reinforcing ring 17 is fixedly connected to the outer surface of the water pipe 5. The other end of the reinforcing ring 17 is connected to the outer surface of the reservoir 1. The reinforcing ring 17 can be used to reinforce the water pipe 5, so that the water it transports can be accurately discharged into the reservoir 1.

[0027] The water treatment component for aerating and oxygenating the extracted groundwater includes an aeration disc 6 installed at the bottom of the reservoir 1 and a spray head 7 connected to the output end of the water storage pipe 5. The spray head 7 sprays the water inside the water storage pipe 5 in a dispersed water flow, greatly increasing the contact area between water and air, and achieving efficient oxygenation of the water injected into the reservoir 1. At the same time, the controller 16 controls the aeration disc 6 to work continuously at the bottom of the reservoir 1. By releasing microbubbles, it accelerates the escape of nitrogen and carbon dioxide from the water, which can effectively prevent the bass from suffering from gas bubble disease.

[0028] An automatic water supply structure is installed between the water storage tank 1 and the fish pond 2 to maintain a suitable water temperature for the growth of bass in the fish pond 2. The automatic water supply structure includes a water temperature sensor 8 installed inside the fish pond 2. A water supply pipe 9 is connected to the top of the outer surface of the fish pond 2, and the input end of the water supply pipe 9 is connected to the bottom of the outer surface of the water storage tank 1. An inlet solenoid valve 10 is installed on the water supply pipe 9. When the water temperature sensor 8 detects that the water temperature inside the fish pond 2 is higher than the set suitable temperature value, it quickly feeds the information back to the controller 16. The controller 16 then immediately controls the inlet solenoid valve 10 to open. Due to the height difference between the liquid levels in the water storage tank 1 and the fish pond 2, and due to water pressure, the low-temperature water inside the water storage tank 1 will naturally flow out under the pressure difference. The water flows into the fish pond 2. As the water level inside the fish pond 2 gradually rises, the water at the bottom will slowly overflow through the drain pipe 11 under water pressure, thus achieving water circulation and renewal and lowering the water temperature inside the fish pond 2. This gentle water temperature adjustment method avoids drastic changes in water temperature, allowing the bass to gradually adapt to the changes and preventing stress reactions caused by sudden drops in water temperature. When the water temperature sensor 8 detects that the water temperature inside the fish pond 2 has dropped to the set suitable temperature range, it will send a signal to the controller 16 again. The controller 16 will then issue a shut-off command to close the inlet solenoid valve 10, stopping the water supply to the fish pond 2 and ensuring that the water temperature is maintained within a suitable range for bass growth.

[0029] The fish pond 2 is equipped with an automatic drainage and sewage discharge structure, which includes a drain pipe 11 connected to the bottom of the fish pond 2. The output end of the drain pipe 11 is located below the top of the fish pond 2. The outer surface of the drain pipe 11 located inside the fish pond 2 has a ring of through holes 12. The outer surface of the drain pipe 11 is connected to a sewage discharge pipe 13. A sewage discharge solenoid valve 14 is installed on the sewage discharge pipe 13. The controller 16 can control the opening and closing of the sewage discharge solenoid valve 14 at regular intervals. By controlling the sewage discharge solenoid valve 14 to open once every two hours, each time it is opened for ten to fifteen seconds. Since the output end of the sewage discharge pipe 13 is lower than the liquid level inside the fish pond 2, under the action of water pressure, impurities and feces deposited at the bottom of the fish pond 2 will enter the drain pipe 11 through the through holes 12 with the water flow and be discharged from the sewage discharge pipe 13, effectively maintaining the cleanliness of the water in the fish pond 2.

[0030] The working principle of this application is as follows: First, the level sensor 3 and the water temperature sensor 8 are activated by the controller 16, putting them into normal working condition. This allows them to monitor the water level and temperature in the reservoir 1 and the fish pond 2. When the level sensor 3 detects that the water level in the reservoir 1 is lower than the preset minimum water level, it immediately sends a signal back to the controller 16. The controller 16 then controls the submersible pump 4 to pump groundwater into the reservoir 1. As the water level in the reservoir 1 rises, when the level sensor 3 detects that the water level has reached the preset maximum water level, it will... The signal is promptly transmitted to the controller 16, which then controls the submersible pump 4 to stop working, thus preventing the water level in the reservoir 1 from becoming too high and overflowing. During the process of pumping groundwater, the sprinkler head 7 sprays the water inside the water storage pipe 5 in a dispersed manner, greatly increasing the contact area between water and air, and achieving efficient oxygenation of the water injected into the reservoir 1. At the same time, the controller 16 controls the aeration disc 6 to work continuously at the bottom of the reservoir 1. By releasing tiny bubbles, it accelerates the escape of nitrogen and carbon dioxide from the water, which can effectively prevent the bass from suffering from gas bubble disease.

[0031] When the water temperature sensor 8 detects that the water temperature inside the fish pond 2 is higher than the set suitable temperature value, it will quickly send the information to the controller 16. The controller 16 will then immediately control the inlet solenoid valve 10 to open. Due to the height difference between the liquid level in the reservoir 1 and the liquid level inside the fish pond 2, the low-temperature water inside the reservoir 1 will automatically flow into the fish pond 2 under the action of the pressure difference. As the water level inside the fish pond 2 gradually rises, since the liquid level inside the fish pond 2 is level with the outlet of the drain pipe 11, the water at the bottom will slowly overflow through the drain pipe 11 under the action of water pressure, thereby realizing the circulation and renewal of the pond water and reducing the water temperature inside the fish pond 2. When the water temperature sensor 8 detects that the water temperature inside the fish pond 2 has dropped to the set suitable temperature range, it will send a signal to the controller 16 again. The controller 16 will then issue a shutdown command to close the inlet solenoid valve 10, stop the water injection into the fish pond 2, and ensure that the water temperature is maintained within the range suitable for the growth of bass.

[0032] To keep the fish pond 2 clean, the controller 16 also has the function of controlling the drain solenoid valve 14 at a time. By controlling the drain solenoid valve 14 to open once every two hours, each time for ten to fifteen seconds, since the output end of the drain pipe 13 is lower than the liquid level inside the fish pond 2, under the action of water pressure, the impurities and feces deposited at the bottom of the fish pond 2 will enter the drain pipe 11 through the through hole 12 and be discharged from the drain pipe 13, effectively keeping the water quality in the fish pond 2 clean, providing a good growth environment for the bass and promoting the healthy growth of the bass.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
