Further, a pressure regulating valve is arranged in the water inlet pipe 7.
As can be seen from the above description, the water flow of the water inlet pipe 7 can adjust the pressure through the pressure adjusting valve, and two functions can be realized after the pressure is adjusted, wherein the first function is to adjust the water pressure to be small, so that the fish eggs are prevented from being damaged due to the impact of the fish eggs. At this time, the water inlet pipe 7 is used only to fill the water to be cleaned in the pipe 6 so that the water passes through the stop valve 61. The second function is that water passes through the stop valve 61, the higher water pressure is adjusted, and the high-pressure water flow washes the fish eggs under the buffering of still water.
Further, the inclination angle of the bottom of the spawning pond 1 is 15-45 degrees.
As can be seen from the above description, a simple and efficient spawning pond 1 structure is provided.
The utility model provides an automatic high-efficient roe collection device's of changing application background does: when roe needs to be collected more automatically and efficiently.
