The second motor 21023 is fixedly connected with the end of the side cylinder 21018. When the air inlet fan 2103 is turned on, it drives air to enter the inside of the inner groove 208 through the connecting pipe 21010, and then enters the bottom pipe 206 and is discharged into the pool water through the exhaust holes 207 to oxygenate the pool water, which is convenient for fish farming. At the same time, when the first motor 205 is turned on, the mounting plate 201 moves horizontally along the sliding groove 202, which is convenient for oxygenating different positions of the pool water, improving the oxygenation range and being convenient for fish farming.A heater 21013 and a cooler 21014 are respectively provided in the heating chamber 21011 and the refrigeration chamber 21012. By moving the baffle 21015, the air entering the heating chamber 21011 and the refrigeration chamber 21012 is controlled, so as to control the heating and refrigeration of the air. After the air is processed, conditioned air is formed. After the conditioned air enters the pool water, the conditioned air exchanges heat with the pool water to adjust the temperature of the pool water, which is convenient for adjusting the temperature of the pool water and convenient for the cultivation of different fish.

[0034] Working principle: When in use, when it is necessary to increase the air in the water, the intake fan 2103 is turned on, driving the outside air to enter the air outlet chamber 2109 through the communication holes 2106 on the two horizontal partitions 2105, then entering the inner groove 208 through the connecting pipe 21010, and finally entering the water through the bottom pipe 206 and the exhaust holes 207 to oxygenate the water. At the same time, the first motor 205 is turned on to make the first screw rod 204 rotate. Since the first screw rod 204 is threadedly connected to the slider 203, the mounting plate 201 is driven to move along the sliding groove 202 to oxygenate different positions in the water, improving the oxygenation effect and facilitating fish farming.

[0035] When it is necessary to adjust the water temperature:

[0036] When the water temperature needs to be increased, the second motor 21023 is turned on at this time. Since the second screw rod 21022 is threadedly connected to the second screw rod 21022, the movable plate 21020 is driven to move horizontally, pulling the two baffles 21015 towards the refrigeration chamber 21012 to seal the upper and lower sides of the refrigeration chamber 21012, so that the air can only enter the bottom pipe 206 through the heating chamber 21011. The heater 21013 is turned on to heat the air. When the heated air enters the water, the heat is transferred to the water, thereby increasing the temperature of the pool water.

[0037] When the water temperature needs to be decreased, a reverse current is passed through the second motor 21023 at this time, so that the two baffles 21015 seal the upper and lower sides of the heating chamber 21011, and the air can only enter the bottom pipe 206 from the refrigeration chamber 21012. The cooler 21014 is turned on to cool the air. After the air enters the water, the temperature of the pool water is decreased.

[0038] After the temperature-regulated air continuously enters the bottom pipe 206 and is discharged from the exhaust holes 207 into the pool water, the first motor 205 is turned on, causing the mounting plate 205 to move horizontally. During the movement, since the gear 2095 at the end is engaged with the rack 2097, the gear 2095 is driven to rotate. The gear 2095 is engaged with the toothed rings 2094 on both sides, causing each bottom pipe 206 to rotate, thereby driving the stirring plate 20910 to rotate continuously, stirring the pool water, improving the contact effect between the pool water and the temperature-regulated air, enhancing the temperature regulation effect of the pool water. Moreover, the connecting rod 2099 and the stirring plate 20910 are respectively provided with a first heat exchange groove 20911 and a second heat exchange groove 20912. After the temperature-regulated air enters, the heat exchange area is increased, improving the temperature regulation effect of the pool water.

The rotating shaft (2096) is rotatably connected to the bottom wall of the mounting plate (201). The gears (2095) are flush with the toothed ring (2094). The gears (2095) and the bottom pipe (206) are arranged in a staggered manner. On both sides of the gear (2095), they are respectively meshed with two toothed rings (2094). On one side of the gear (2095) at the end, a rack (2097) is meshed and connected. The rack (2097) is arranged along the length direction of the pool body (1). On the side of the rack (2097) close to the inner wall of the pool body (1), fixing rods (2098) are symmetrically installed. The fixing rods (2098) are fixedly connected to the inner wall of the pool body (1).

5. An adjustable-temperature fish polyculture pond for precious fish species according to claim 1, characterized in that: Connecting rods (2099) are installed on the outer side of the bottom pipe (206) at equal angles. The connecting rods (2099) are arranged in an inverted L shape. On the side of the connecting rod (2099) away from the bottom pipe (206), stirring plates (20910) are equidistantly installed. A first heat exchange groove (20911) is formed inside the connecting rod (2099). The first heat exchange groove (20911) is communicated with the inside of the bottom pipe (206). A second heat exchange groove (20912) is formed inside the stirring plate (20910). The second heat exchange groove (20912) is communicated with the inside of the first heat exchange groove (20911).
