Description

Technical Field

[0001] This utility model belongs to the field of sturgeon artificial breeding technology, specifically a constant temperature breeding pond for sturgeon farming. Background Technology

[0002] Sturgeon grow rapidly, grow to a large size, have delicious and nutritious meat, and possess high economic value. However, due to overfishing and environmental degradation, sturgeon catches have decreased dramatically, leading to the rise of artificial sturgeon farming. my country's sturgeon farming industry began in the 1990s and has now developed into the world's largest producer of sturgeon and the largest exporter of sturgeon caviar.

[0003] Suitable water temperature is one of the essential conditions for sturgeon aquaculture. The optimal water temperature for sturgeon aquaculture is around 20 degrees Celsius. Maintaining a suitable water temperature during the sturgeon's growth period can improve feed conversion rate and shorten the time it takes for sturgeon to grow into marketable fish. Currently, the commonly used aquaculture pond design usually relies on heaters in fixed locations to maintain water temperature through natural heat transfer. While this method can regulate the water temperature, the limitations of heat transfer lead to uneven water temperature distribution within the pond, with some areas being too cold, failing to provide a suitable, stable, and uniform water temperature environment for sturgeon growth. Therefore, it is necessary to design a constant-temperature aquaculture pond for sturgeon aquaculture that avoids uneven water temperature distribution. Utility Model Content

[0004] To address the above technical problems, this utility model provides a constant-temperature culture pond for sturgeon farming that avoids uneven water temperature distribution, thereby solving the problem that excessively cold water temperature has an adverse effect on sturgeon growth.

[0005] To solve the above technical problems, the technical solution of this utility model is as follows: a constant temperature culture pond for sturgeon farming, comprising a culture pond, a forward and reverse motor fixedly connected to the upper side of the culture pond, a threaded rod fixedly connected to the output end of the forward and reverse motor, two fixed seats fixedly connected to the upper end of one side of the culture pond, the two ends of the threaded rod being rotatably connected to the fixed seats respectively, a sliding rod parallel to the threaded rod fixedly connected between the two fixed seats, a threaded block slidably sleeved on the sliding rod, the threaded block being threadedly connected to the threaded rod, and a water supply pipe fixedly connected to the threaded block. One end of the water supply pipe extends downward into the aquaculture pond and is fixedly connected to several vertically arranged water outlet pipes. The other end is connected to a circulating water pump via a flexible hose. The input end of the circulating water pump is connected to a water treatment tank. The bottom of the water treatment tank is connected to the inside of the aquaculture pond via an inlet pipe. The water treatment tank and the circulating water pump are both fixedly connected to one side of the aquaculture pond. An electric heater is installed inside the water treatment tank. A temperature sensor is installed inside the aquaculture pond. The temperature sensor is communicatively connected to a controller. The forward and reverse motors and the electric heater are both controlled by the controller.

[0006] Furthermore, a coil is installed on the outer wall of the aquaculture pond, and the flexible hose is wound inside the coil.

[0007] Furthermore, a delivery pipe is fixedly connected to the top of the water treatment tank, and the other end of the delivery pipe is fixedly connected to the input end of the circulating water pump. A filter plate is installed inside the water treatment tank between the inlet pipe and the electric heater. A drain pipe is fixedly connected to the bottom of the water treatment tank, and a valve is installed on the drain pipe.

[0008] Furthermore, a replacement window is provided on the side wall of the water treatment tank at the location of the filter plate, and a sealed door is hinged to one side of the replacement window.

[0009] This utility model has the following advantages compared with the prior art:

[0010] 1. This utility model, by installing a reversible motor, a threaded block, a threaded rod, a sliding rod, a water supply pipe, and a water outlet pipe on the upper side of the breeding pond, allows the reversible motor to continuously rotate forward and backward. This drives the threaded block and the water supply pipe to reciprocate along the threaded rod and the sliding rod, thereby continuously delivering water of suitable temperature for sturgeon growth from the outlet pipe to all parts of the breeding pond. This avoids uneven horizontal distribution of water temperature within the breeding pond. The vertically positioned outlet pipe can guide the water flow upward or downward, further preventing uneven vertical distribution of water temperature within the breeding pond. This solves the problem of excessively cold water in the breeding pond negatively impacting sturgeon growth.

[0011] 2. This utility model, by installing a coiler on one side of the breeding pond, allows the flexible hose to be wound and stored on the coiler, avoiding the hose from getting tangled and knotted when moving during use, thus affecting normal use; by setting a filter screen in the water treatment tank and connecting it to the drain pipe, the dirt mixed in the pond water can be filtered and separated before the heated water is heated, reducing the probability of sturgeon getting fish diseases due to poor water quality, and further ensuring the normal growth of sturgeon.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 4 The diagram shows a constant-temperature culture tank for sturgeon farming, comprising a culture tank 1. A reversible motor 2 is fixedly connected to the upper side of the culture tank 1, and a threaded rod 3 is fixedly connected to the output end of the motor 2. Two fixed seats 5 are fixedly connected to the upper side of one side of the culture tank 1. The two ends of the threaded rod 3 are rotatably connected to the fixed seats 5 respectively. A sliding rod 4 parallel to the threaded rod 3 is fixedly connected between the two fixed seats 5. A threaded block 6 is slidably fitted on the sliding rod 4 and threadedly connected to the threaded rod 3. A water supply pipe 7 is fixedly connected to the threaded block 6. One end of the water supply pipe 7 extends downward into the culture tank 1 and is fixedly connected to several vertically arranged water outlet pipes 8. The water flowing out through the vertically arranged water outlet pipes 8 flows upward or downward, which can effectively avoid uneven water temperature distribution in the culture tank 1. The other end of the water supply pipe 7 is connected to a circulating water pump 10 through a flexible hose 9. The flexible hose 9 is a braided hose. The input end of the circulating water pump 10 is connected to a water treatment system. The bottom of the water treatment tank 11 is connected to the inside of the breeding pond 1 through the water inlet pipe 12. The water treatment tank 11 and the circulating water pump 10 are both fixedly connected to one side of the breeding pond 1. An electric heater 13 is installed inside the water treatment tank 11. A temperature sensor is installed inside the breeding pond 1. The temperature sensor is installed below the water surface of the breeding pond 1 and is connected to the controller. The forward and reverse motor 2 and the electric heater 13 are both controlled by the controller. The controller is a PLC controller. The minimum value of the optimal water temperature required for sturgeon growth is set as the temperature set value for the controller to control the electric heater 13 to start or stop. Under the control of the controller, the forward and reverse motor 2 periodically changes the rotation direction of the output end, thereby driving the threaded rod 3 to periodically rotate forward and reverse. The time interval between two time points when the rotation direction of the forward and reverse motor is changed in the controller is set as the time taken for the threaded block 6 to move from one end of the threaded rod 3 to the other end.

[0019] To facilitate the storage of the hose 9 and prevent it from becoming tangled and knotted, a coiler 14 is installed on the outer wall of the aquaculture pond 1, and the hose 9 is wound inside the coiler 14.

[0020] In order to treat the water in the breeding pond 1 through the water treatment tank 11 and then transport it to the breeding pond 1 through the circulating water pump 10, a conveying pipe 15 is fixedly connected to the top of the water treatment tank 11, and the other end of the conveying pipe 15 is fixedly connected to the input end of the circulating water pump 10. A filter plate 16 is installed inside the water treatment tank 11 between the water inlet pipe 12 and the electric heater 13. A sewage pipe 17 is fixedly connected to the bottom of the water treatment tank 11. A valve is installed on the sewage pipe 17. By opening the valve on the sewage pipe 17, the dirt accumulated in the water treatment tank 11 can be discharged.

[0021] To facilitate cleaning and replacement of the filter plate 16 inside the water treatment tank 11, a replacement window is provided on the side wall of the water treatment tank 11 at the location of the filter plate 16, and a sealed door is hinged to one side of the replacement window.

[0022] The specific working process of this utility model is as follows:

[0023] The circulating water pump 10 and the forward / reverse motor 2 are started. The controller controls the forward / reverse motor 2 to continuously change the direction of rotation, driving the threaded rod 3 to rotate forward and reverse continuously. This causes the threaded block 6 to move back and forth on the threaded rod 3, thereby driving the water supply pipe 7 and the water outlet pipe 8 to move back and forth in the breeding pond 1. At the same time, the circulating water pump 10 draws water from the breeding pond 1, which flows through the inlet pipe 12 into the bottom of the water treatment tank 11, is filtered by the filter plate 16, flows through the electric heater 13, and finally exits through the top of the water treatment tank 11 into the delivery pipe 15, enters the circulating water pump 10, and is then transported into the hose 9. Water from the supply pipe 7 is eventually discharged through the outlet pipe 8 and re-enters the breeding pond 1. As the supply pipe 7 and outlet pipe 8 reciprocate, the water is continuously transported to various parts of the breeding pond 1. During this process, the temperature sensor continuously monitors the water temperature in the breeding pond 1 and transmits the results to the controller. When the controller receives a real-time water temperature lower than the set value, the controller controls the electric heater 13 to start, heating the water flowing through the water treatment tank 11 to maintain a suitable water temperature for sturgeon growth. When the controller receives a real-time water temperature higher than the set value, the controller controls the electric heater 13 to turn off.
