Description

Technical Field

[0001] The utility model relates to the technical field of spawning ponds, in particular to a constant temperature spawning pond for fish farming. Background Art

[0002] In the process of raising fish, fish farms need to breed fish. After mating, female fish can be placed in the spawning pool for heat preservation. After a period of feeding, female fish can lay eggs. However, in the prior art, when controlling the water temperature in the spawning pool, the water temperature is heated by electric heating pipes. The heating method of electric heating pipes will cause the local water temperature to be too high, resulting in uneven temperature of the spawning pool as a whole, affecting the survival rate of the young fish in the pool. In addition, the pool needs to be insulated by a cover plate to reduce water evaporation, but the cover plate is too large in diameter, which makes it difficult to open the cover plate, affecting the normal use of the spawning pool. Therefore, the prior art needs to be improved. Utility Model Content

The connecting pipe 5 can supply water to the inside of the annular pipe 6. A dividing mesh plate 8 is movably connected to the middle part of the inner wall of the pool body 1. The dividing mesh plate 8 is connected to the central pipe 2 by a threaded connection. The mesh diameter of the dividing mesh plate 8 is slightly larger than the length of the fry.

[0021] See also Figure 1 , Figure 2 , Figure 3The protective mechanism 7 includes a fixing plate 71, and the upper part of the inner wall of the annular tube 6 is fixedly connected to the fixing plate 71, and the interior of the fixing plate 71 is slidably connected to a connecting nail 72, and the upper end of the connecting nail 72 is fixedly connected to a protective cover 73, and a spring 74 is provided on the outer side of the connecting nail 72.

[0022] The specific implementation process of the utility model is as follows: when in use, the submersible pump 4 is started, and after the submersible pump 4 generates suction, the water outside the central tube 2 is sucked into the inside of the submersible pump 4. When the water flows through the electric heating tube 3, it can exchange heat with the electric heating tube 3. The heated water flows into the inside of the annular tube 6 through the connecting tube 5. When the thrust of the water flow on the protective cover 73 is greater than the elastic force of the spring 74, the protective cover 73 moves. When the protective cover 73 is separated from the annular tube 6, the heated water flow can be discharged into the inside of the pool body 1 to heat the water temperature inside the pool body 1, thereby making the water temperature inside the pool body 1 uniformly increased. When heating is not needed, the thrust of the water flow on the protective cover 73 disappears, and the spring 74 is reset. The spring 74 can drive the protective cover 73 to cover the outside of the water outlet of the annular tube 6 through the elastic force, so as to prevent the young fish from entering the inside of the annular tube 6.

[0023] When it is necessary to open the cover 9, start the motor 14, which drives the screw 11 to rotate. During the rotation, the screw 11 can drive the pull rod 13 to move through the thread cooperation with the threaded frame 12. During the movement, the pull rod 13 can drive the cover 9 to flip upward through the hinge between the cover 9, so that the cover 9 can be easily opened.
