Figure 3 、 5 As shown, when the second filter screen 16 is used for a long time, when cleaning the second filter screen 16, the surface of the second filter screen 16 can be cleaned by pulling the limit rod 17 to separate the limit rod 17 from the limit groove 19. At the same time, when installing the second filter screen 16, after the second filter screen 16 is attached to the entrance of the through-tube 12, the limit rod 17 is loosened, so that the limit rod 17 descends under the action of the second spring 18, thereby engaging the limit rod 17 with the limit groove 19, so that the second filter screen 16 is installed on the through-tube 12. At the same time, the second spring 18 can be coated with a waterproof and anti-corrosion coating to increase the service life of the second spring 18. At the same time, the second spring 18 is a tension spring in the prior art.

[0031] Working principle: Before using the seahorse seedling water heating and insulation device, it is necessary to first check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, first, when the first filter screen 14 needs to be taken out for cleaning or replacement, the threaded rod 1503 is rotated so that the rotation of the threaded rod 1503 can drive the threaded sleeve 1504 to rise. At the same time, both sides of the threaded sleeve 1504 are fixedly connected to the slider 1505, and the slider 1505 is slidably connected to the slide 1506. Through the cooperation between the slider 1505 and the slide 1506, the threaded sleeve 1504 can be limited, so that the threaded sleeve 1504 can move on the thread. Through the movement of the threaded sleeve 1504, The extension box 1507 can be driven to rise, and the rise of the extension box 1507 can drive the pressure block 1511 to rise, so that the pressure block 1511 no longer squeezes the bottom of the first filter screen 14. After the extension box 1507 rises to a certain position, the extension plate 1510 is pushed to move the extension plate 1510. At the same time, the movement of the extension plate 1510 squeezes the first spring 1514, so that the first spring 1514 is deformed. At the same time, after the extension plate 1510 drives the pressure block 1511 to move to a certain position, When the pressing block 1511 is not above the first filter screen 14, the first filter screen 14 is separated from the card slot 13 by pulling the first filter screen 14, so that the first filter screen 14 can be taken out for cleaning and replacement. At the same time, when installing the first filter screen 14, after the first filter screen 14 is engaged with the card slot 13, the extension plate 1510 is loosened so that the extension plate 1510 is restored to its original position under the action of the first spring 1514, so that the extension plate 1510 can drive the pressing block 1511 to return to its original position, and then the threaded rod 1503 is rotated to make the threaded rod 1503 drives the threaded sleeve 1504 to descend, and the descent of the threaded sleeve 1504 can drive the extension box 1507 to descend, and the descent of the extension box 1507 can drive the pressure block 1511 to descend. After the pressure block 1511 descends to a certain position, the pressure block 1511 can press the first filter 14, so that the engagement between the first filter 14 and the card slot 13 can be tighter, so that the cleaning or replacement of the first filter 14 can also be more convenient, thereby improving the work efficiency of the staff.
[0032] Secondly, by setting a second filter screen 16, a limiting rod 17, a second spring 18 and a limiting groove 19, the second filter screen 16 is located at the entrance of the through-tube 12. When the water source is located at the position of the through-tube 12, the water source flows through the through-tube 12 to the other side of the partition 11, and then is transported to the inside of the heating box 6 through the connecting pipe 10, the second water pump 9 and the outlet pipe 7 to heat the water source. Then, the heated water source is transported to the inside of the water tank 1 through the water inlet pipe 5, the first water pump 4 and the delivery pipe 3, thereby completing the recycling of the water source. At the same time, when the water source flows into the other side of the partition 11 through the through-tube 12, the second filter screen 16 can be used to perform a preliminary filtration of impurities in the water source. At the same time, the mesh number of the second filter screen 16 is 40 meshes, and the mesh size is 0.445MM, and the seahorse seedling breeding The size is 0.8-1CM, which means that when the water source passes through the second filter screen 16 and the through-tube 12, the seahorse seedlings will not enter the interior of the through-tube 12. At the same time, when the second filter screen 16 is used for a long time, when the second filter screen 16 is cleaned, the limit rod 17 is pulled to separate the limit rod 17 from the limit groove 19, and then the surface of the second filter screen 16 can be cleaned. At the same time, when the second filter screen 16 is installed, after the second filter screen 16 is attached to the entrance of the through-tube 12, the limit rod 17 is loosened so that the limit rod 17 drops under the action of the second spring 18, so that the limit rod 17 is engaged with the limit groove 19, so that the second filter screen 16 is installed on the through-tube 12. At the same time, the second spring 18 can be coated with waterproof and anti-corrosion paint to increase the service life of the second spring 18.
