Detailed Description

As shown in fig. 1, a water-saving trout fry rearing pond comprises a pond body 1, wherein a water replenishing pipe 2 is arranged on the pond body 1, the water replenishing pipe 2 is used for replenishing water into the pond body 1, a first valve 3 is arranged on the water replenishing pipe 2, the bottom of the pond body 1 is funnel-shaped and forms a water outlet 4, the funnel-shaped arrangement can enable impurity dirty phase water outlet 4 at the bottom of the pond body 1 to be collected in a centralized manner and be discharged conveniently, a separation net 5 is arranged at the water outlet 4, the mesh size of the separation net 5 is smaller than the size of fries, the separation net 5 is used for preventing the trout fries from flowing out of the water outlet 4 under the action of water flow during water discharge, a first water discharge pipe 6 is connected at the water outlet 4, a second valve 7 is arranged on the first water discharge pipe 6, a filter box 8 is connected at the other end of the first water discharge pipe 6, a box cover 9 is arranged on the, wherein the mesh number of the coarse filter screen 10 is 7-9, the mesh number of the fine filter screen 11 is 10-14, when impurities are gathered to a certain degree, the box cover 9 can be opened for cleaning, the other side of the filter box 8 opposite to the first drain pipe 6 is connected with a water conveying pipe 12, the other end of the water conveying pipe 12 is connected with a standing pool 13, the standing pool 13 is used for standing filtered water to improve the purification effect, the standing pool 13 is connected with a return pipe 14, the other end of the return pipe 14 is led into the pool body 1, the return pipe 14 is provided with a water pump 15, the filtered water is conveyed back to the pool body 1 through the return pipe 14 after standing in the standing pool 13 for a period of time to complete the purification circulation, the pool 1 is also provided with an impeller 16, the impeller 16 is fixed on the pool body 1 through a support and the like, the impeller 16 is positioned at a port close to the return pipe 14, the standing pool is also connected with a second, the second water discharge pipe 17 is used for discharging and replacing all water after the water in the fish pond is used for a period of time and the water quality is deteriorated and cannot be effectively purified.

When the utility model is used, when the trout fry is cultivated in the pool body 1, excrement and urine or other impurities settle at the bottom of the pool body 1, the second valve 7 and the water pump 14 are opened at the moment, the pool water in the pool body 1 flows into the filter box 8 through the first drainage pipe 6 through the drainage port 4, and because the bottom of the pool body 1 is funnel-shaped, the impurities at the bottom of the pool body 1 can be gathered to the drainage port 4 to ensure that all the impurities at the bottom of the pool body 1 are completely discharged without residue, in the process, the isolation net 4 isolates the fry in the pool body 1 to prevent the fry from being washed away with water flow to cause property loss, the pool water is primarily filtered in the filter tank 8 through the coarse filter screen 10 to filter some larger impurities, then filtered again by a fine filter screen 11, finally enters a standing pool 13 by a water delivery pipe 12, when the water level in the standing tank 13 reaches the bottom end of the water return pipe 14, water in the standing tank 15 is pumped back into the tank body 1 through the water return pipe 14 to complete purification circulation; meanwhile, when the water return pipe conveys water to the pool body 1, the water flow of the water return pipe 14 hits the impeller 16 and enables the impeller 16 to rotate, and the impeller 16 breaks up the water flow to be scattered on the surface of the pool water while rotating, so that the oxygen content in the water is increased; after the filter box is used for a period of time, the second valve 7 and the water pump 15 can be closed to stop circulation, and the box cover 9 on the filter box 8 is opened to remove impurities in the filter box 8, so that the filter effect is prevented from being influenced by excessive impurities; when the water in the pool body 1 is used for a period of time and cannot be purified through circulating filtration, the water in the pool body 1 can be discharged through the third drain pipe 17 by opening the third valve 18, and then the first valve 3 is opened to replace fresh water through the water replenishing pipe 2 so as to ensure the fry culturing effect.
