Detailed ways

The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

An embodiment of the utility model: a hatching device for spotted carp, as shown in Figures 1-4, includes a hatching basin 1, a hatching frame 2 that can float on the water surface, and a circulating water device arranged in the hatching basin 1, wherein the circulating water device includes a variable frequency water pump 3 placed in the hatching basin 1, the variable frequency water pump 3 is connected to a horizontal water pipe 5 located above the hatching basin 1 via a vertical water pipe 4, the horizontal water pipe 5 is provided with a plurality of water spray holes 6 uniformly and obliquely downwardly along its length direction, and an oxygenation device 7 and a water level regulating device are also arranged in the hatching basin 1.

During use, the hatching frame 2 floating on the surface of the water body is used to realize the embryonic development of the fertilized eggs of the spotted bream. The hatching frame 2 is a mesh frame structure, which is connected to the hatching basin 1 through the mesh. The variable frequency water pump 3 extracts water from the hatching basin 1, inputs it into the horizontal water pipe 5 through the vertical water pipe 4, and then sprays it out from the water spray hole 6 arranged obliquely downward, acting obliquely on the surface of the water body in the hatching basin 1, so that the water body in the hatching basin 1 flows, thereby driving the hatching frame 2 to move with the water body, and the flowing water can increase the dissolved oxygen in the water body, and at the same time stimulate the embryonic development of the fertilized eggs of the spotted bream, thereby improving the hatching rate of the fertilized eggs of the spotted bream. The oxygenation device 7 is a plurality of oxygen pumps arranged at the bottom edge of the hatching basin 1, which are used to provide oxygen to the water body. The oxygenation power of the oxygen pump can be small bubbles. During the hatching process, new water is injected into the hatching basin 1 through the pipeline, and the water level in the hatching basin 1 is controlled by the water level regulating device.

A plurality of floating balls 8 are fixed around the hatching frame 2, and the floating balls 8 enable the hatching frame 2 to float on the surface of the water body.

The length of the transverse water pipe 5 is less than or equal to the inner radius of the hatching basin 1. This arrangement enables the water flow sprayed from the transverse water pipe 5 to act only on half of the hatching basin 1, thereby ensuring that the water in the hatching basin 1 can flow. The water spray hole 6 is arranged at an angle of 45° downward.

The water level regulating device includes a through hole arranged at the bottom center of the hatching basin 1, a small water pipe 9 arranged vertically is bonded and fixed at the through hole, a large water pipe 10 is sleeved on the outside of the small water pipe 9, the bottom of the large water pipe 10 is bonded and fixed on the bottom surface of the hatching basin 1, a plurality of filtering holes 11 are arranged around the lower part of the large water pipe 10, and the height of the small water pipe 9 is smaller than the large water pipe 10, and smaller than the depth of the hatching basin 1. During use, the water in the hatching basin 1 enters between the small water pipe 9 and the large water pipe 10 through the filtering holes 11. When the top surface of the water entering is higher than the top surface of the small water pipe 9, the water will enter the small water pipe 9 and be discharged from the small water pipe 9, so that the water level in the hatching basin 1 is controlled by this structure.

The top surface of the through hole is a countersunk structure, and the outer wall of the bottom of the large water pipe 10 is bonded and fixedly connected to the side wall of the countersunk hole. This arrangement enables the large water pipe 10 to be firmly fixed.

The small water pipe 9 is composed of a lower small water pipe 901 and an upper small water pipe 902, which are connected by threads. During use, the upper small water pipe 902 is rotated to adjust the top surface height of the upper small water pipe 902, that is, to adjust the height of the small water pipe 9, thereby adjusting the water level in the hatching basin 1.

As shown in FIG3 , since the top surface of the upper small water pipe 902 is always lower than the top surface of the large water pipe 10, when adjusting the height of the upper small water pipe 902, one needs to put one's hand into the inside of the large water pipe 10, which is troublesome to adjust. Therefore, a structure as shown in FIG4 is designed: a plurality of water inlets 903 are arranged at the same height around the lower part of the upper small water pipe 902. By arranging a plurality of water inlets 903 on the upper small water pipe 902, when the water between the small water pipe 9 and the large water pipe 10 rises to the height of the water inlet 903, the water can enter the small water pipe 9 from the water inlet 903, instead of entering the small water pipe 9 from the top surface of the small water pipe 9. The height of the water inlet 903 can be adjusted by rotating the upper small water pipe 902, thereby realizing the adjustment of the water level in the hatching basin 1. In order to facilitate the rotation of the upper small water pipe 902 , when the water inlet 903 is just blocked by the lower small water pipe 901 , the top surface of the upper small water pipe 902 is at least 5 cm higher than the top surface of the large water pipe 10 .
