[0002] The statements in this section merely provide background technology related to the present invention and do not necessarily constitute prior art.

[0003] Water quality management is the key to the cultivation of white shrimp. It is necessary to ensure appropriate water quality conditions, including appropriate water temperature, salinity and pH value, and ensure good water circulation, as well as appropriate water depth and pond size. White shrimp has relatively high requirements for the water depth, water quality, oxygen and other conditions of the cultivation environment. Its growth requires appropriate water temperature and light. White shrimp is more sensitive to temperature. It is necessary to ensure that the water temperature is appropriate during cultivation. Higher or lower temperatures will affect the health and growth of white shrimp. If the water is not changed in time or the water temperature is not suitable, it will affect the good growth of white shrimp, resulting in increased cultivation costs and reduced profits.

[0004] The Chinese utility model patent with the announcement number CN218515009U discloses an adjustment device for a white shrimp farming equipment. By setting a fence device and an adjustment device, the height of the fence can be adjusted to adapt to the different sizes of white shrimps. At the same time, the depth of the fence pool can be adjusted according to the amount of shrimps. However, although the above-mentioned adjustment device can adjust the height of the fence of the farming pool, it cannot adjust the water temperature of the farming. Utility Model Content

[0040] like Figures 1 to 6As shown, the embodiment of the utility model provides a water temperature control device for South American shrimp farming, including: a flow regulating mechanism 3 connected to the farming equipment 2 through a water inlet pipe 1; the flow regulating mechanism 3 is connected to a refrigeration device 5 through a first shunt pipe 4, and the flow regulating mechanism 3 is connected to a heating device 7 through a second shunt pipe 6. It also includes a first water pump 9 connected to the farming equipment 2 through a water outlet pipe 8, the output end of the first water pump 9 is connected to a filter box 10, the output end of the filter box 10 is connected to a second water pump 11, and the output end of the second water pump 11 is connected to the refrigeration device 5 and the heating device 7. In specific use, the first water pump 9 pumps the water in the breeding equipment 2 through the water outlet pipe 8, passes through the filter box 10, and then the second water pump 11 inputs the filtered water into the refrigeration equipment 5 and the heating equipment 7 respectively. The refrigeration equipment 5 can cool and cool the water and temporarily store it, and the heating equipment 7 can heat and heat the water and temporarily store it. Then, the water in the refrigeration equipment 5 and the heating equipment 7 is flow-regulated by the flow regulating mechanism 3 to regulate the amount of hot water or cold water entering the breeding equipment 2, thereby realizing the regulation of the water temperature in the breeding equipment 2. At the same time, the filtration and recycling of the water in the breeding equipment 2 is also realized. For example, when breeding shrimp fry, the breeding equipment 2 can be a breeding barrel, and a thermometer 38 is provided on the breeding barrel to measure the temperature of the water in the breeding barrel in real time. If the water temperature in the breeding barrel is too high, the flow rate of the water heated by the heating device 7 can be adjusted to be reduced or closed through the flow regulating mechanism 3, or the flow rate of the water cooled by the refrigeration device 5 can be increased; if the water temperature in the breeding barrel is too low, the flow rate of the water cooled by the refrigeration device 5 can be adjusted to be reduced or closed through the flow regulating mechanism 3, or the flow rate of the water heated by the heating device 7 can be increased.

[0041] In a specific embodiment, the refrigeration device 5 adopts the method of heat exchange between medium and water in the prior art. For example, the refrigeration device 5 can be configured to include a refrigeration box, which is connected to the first shunt pipe 4 and the second water pump 11. The refrigeration box can temporarily store water. A coil is arranged in the refrigeration box, and a refrigeration medium flows in the coil. The water is cooled and refrigerated by heat exchange between the refrigeration medium and water. The coil is connected to an external refrigerator, and the external refrigerator cools and cools the refrigeration medium in the coil. The coil can be arranged on the wall of the refrigeration box. The above-mentioned heating device 7 adopts the prior art to heat water through electric heating pipes, steam heating or other heating methods. For example, the heating device 7 can be configured to include a heating box, which is connected to the second shunt pipe 6 and the second water pump 11, and an electric heating device is arranged in the heating box to heat water through the electric heating device; or a coil is arranged on the wall of the heating box, and steam heated by an external device flows in the coil to transfer heat to the water, thereby achieving heating and temperature increase of the water in the heating box. For the above-mentioned filtering device, those skilled in the art can select a suitable device for filtering water in the prior art, which can also be configured to include a filter box connected to the first water pump 9 and the second water pump 11, in which a filter element is arranged. First, a pipe connected to the first water pump 9 extends into the filter box and is connected to the inlet of the filter element. The connecting pipe of the second water pump 11 is directly connected to the filter box.

[0042] In a specific embodiment, specifically, the flow regulating mechanism 3 includes a mixing box 12 connected to the refrigeration device and the heating device through a first shunt pipe 4 and a second shunt pipe respectively. The water heated by the heating device and the water cooled by the refrigeration device are mixed in the mixing box 12 and can be temporarily stored. An extension channel 13 connected to the water inlet pipe 1 is provided on the inner wall of the mixing box 12; a flow regulating plate 14 is slidably provided in the extension channel 13, and the flow regulating plate 14 moves along the circumferential direction of the extension channel 13. A plurality of water holes 15 are evenly provided on the radial end face of the extension channel 13. By adjusting the position of the flow regulating plate 14 in the extension channel 13, the amount of connectivity between the extension channel 13 and the water inlet pipe 1 is adjusted. Specifically, for example, the water in the mixing box 12 flows to the water inlet pipe 1 through the water holes 15 between the flow regulating plate 14 and the box wall of the mixing box 12. Figure 2 As shown in the figure, when the flow regulating plate 14 moves toward the water inlet pipe 1, the number of water holes 15 between the flow regulating plate 14 and the box wall of the mixing box 12 decreases, thereby reducing the flow to the water inlet pipe 1; when the flow regulating plate 14 moves away from the water inlet pipe 1, the number of water holes 15 between the flow regulating plate 14 and the box wall of the mixing box 12 increases, thereby increasing the flow.

[0043] In order to enable the flow regulating plate 14 to move in the extension channel 13 along the axial direction of the extension channel 13, a support cylinder 16 is rotatably provided in the mixing box 12. The support cylinder 16 is a hollow structure, and a reciprocating motion mechanism 17 is slidably provided in its internal space. The reciprocating motion mechanism 17 is connected to the flow regulating plate 14, and the reciprocating motion mechanism 17 reciprocates along the support cylinder 16 to adjust the position of the flow regulating plate 14 in the extension channel 13. In this embodiment, in order to realize the rotation of the support tube 16 in the mixing box 12, a limit card shell 18 is provided at the top of the mixing box 12, and the top of the support tube 16 can be movably extended into the limit card shell 18. For example, a sealed bearing (not shown in the figure) is provided on the top box wall of the mixing box 12, and the support tube 16 extends out of the sealed bearing and rotates relative to the top box wall of the mixing box 12. A rotating bearing is provided at the bottom of the mixing box 12, and the bottom of the support tube 16 is inserted into the inner ring of the rotating bearing. A rotating handle 19 is connected to the top of the support tube 16, and the rotating handle 19 can movably extend out of the limit card shell 18. The support tube 16 is rotated by rotating the handle 19 to realize the rotation of the support tube 16 in the mixing box 12.

[0044] Among them, Figure 4As shown, the reciprocating mechanism 17 includes a driving rod 20 slidably disposed in the support tube 16 and movably extending out of the limit card shell 18, and a rotating sleeve 21 is provided on the driving rod 20, and a linkage rod 22 is pivotally connected to the outer side of the rotating sleeve 21, and the linkage rod 22 can movably extend out of the support tube 21 and be pivotally connected to the flow regulating plate 14. The driving rod 20 can move up and down along the support tube 16, and the up and down movement of the driving rod 20 drives one end of the pivoted linkage rod 22 connected to the rotating sleeve 21 to move up and down, so that the other end of the linkage rod 22 drives the flow regulating plate 14 to move axially in the extension channel 13, thereby changing the position in the extension channel 13. In order to realize the up and down movement of the driving rod 20, a threaded tube 24 with an internal thread 23 is provided on the top of the limit card shell 18, and the outer surface of the driving rod 20 is provided with an external thread 25 matching the internal thread 23. The threaded tube 24 extends out of the top of the driving rod 20. Through the cooperation of the internal thread 23 and the external thread 25, the driving rod 20 can be screwed to move up and down. For example, the driving rod 20 can be raised by rotating counterclockwise, and can be lowered by rotating clockwise. The rising of the driving rod 20 pulls one end of the linkage rod 22 to rise, and the rising of the linkage rod 22 drives the flow regulating plate 14 away from the water inlet pipe 1. On the contrary, the descent of the driving rod 20 pushes one end of the linkage rod 22 to fall, and the descent of the linkage rod 22 pushes the flow regulating plate 14 to move in the direction close to the water inlet pipe 1. Specifically, a reciprocating opening 32 for the linkage rod 22 to extend is provided on one side of the support tube 16; one end of the linkage rod 22 is pivotally connected to the first connecting ear plate 33 through a pivot, and the other end of the linkage rod 22 extends out of the reciprocating opening 32 and is pivotally connected to the second connecting ear plate 34 through a pivot. A first connecting ear plate 33 is provided on the radial end surface of the rotating sleeve 21, and a second connecting ear plate 34 is provided on the side surface of the flow regulating plate 14. In order to ensure the stability of the movement of the flow regulating plate 14 in the extension channel 13, two opposite axial sliding grooves 42 can be provided on the radial end surface of the extension channel 13, and then a corresponding slider 43 is provided on the flow regulating plate 14. The slider 43 slides in the axial sliding groove 42 to ensure the stable movement of the flow regulating plate 14 in the extension channel 13.

[0045] In a specific embodiment, in combination Figure 3 , Figure 5As shown, a limiting through hole 26 is provided on one side of the limiting housing 18, and the rotating handle 19 can movably extend out of the limiting through hole 26. The rotating handle 19 rotates within the range of the limiting through hole 26, and a plurality of clamping holes 27 are provided on the other side of the limiting housing 18. A blind groove 28 is provided on the support tube 16, and an elastic member 29 is provided in the blind groove 28. The elastic member 29 is connected with a clamping column 30 that can be clamped into the clamping hole 27. For example, when the rotating handle 19 rotates in the limiting through hole 26, the clamping column 30 can be clamped into the clamping hole 27, so that the rotation angle of the support tube 16 can be limited. A first through hole 35 communicating with the first shunt pipe 4 is provided on the wall of the mixing box 12, and a second through hole (not shown in the figure) communicating with the second shunt pipe 6 is provided on the wall of the mixing box 12; and an arc-shaped baffle 36 that can slide along the wall of the mixing box 12 is provided in the mixing box 12. Specifically, a connecting rod 37 is connected to the radial end surface of the support tube 16, and the arc-shaped baffle 36 is connected through the connecting rod 37. The rotation of the support tube 16 can drive the arc-shaped baffle 36 to slide along the inner wall of the mixing box 12, and the change of the position of the arc-shaped baffle 36 in the mixing box 12 can adjust the opening and closing degree of the first through hole 35 and the second through hole, thereby adjusting the flow rate of the refrigerated water and the flow rate of the heated water entering the mixing box 12, thereby adjusting the water temperature.

The limit block 31 is provided with a through passage 44 for the driving rod 20 to pass through, and the driving rod 20 passes through the through passage 44 and extends into the support tube 16.

[0047] In a specific embodiment, the water temperature control equipment for South American shrimp farming may also include a support frame 39, on which a flow regulating mechanism, a refrigeration device, and a heating device are all arranged. The water inlet pipe 1 is connected to the farming equipment 2 above the support frame 39, and the first water pump, the filtering device, and the second water pump are all fixedly arranged below the support frame 39. The second water pump 11 is connected to a connecting pipe 41 arranged above the support frame 39 through a water pipe 40.
