Abstract
Description
Technical Field
[0001] The utility model relates to a circulating ecological fish farming device. Background Art
[0002] Farming fish in canvas ponds is a popular way of farming fish. Farming in canvas ponds does not require excavation of the ground, so approval is more convenient and does not damage the ground structure. In the existing technology, farming in canvas ponds mainly relies on a large amount of aeration to increase the oxygen content in the water, but the feces produced by fish activities will be deposited at the bottom of the canvas pond. A large amount of aeration will cause this part of the feces to rise, causing turbidity in the water and making the fish sick. The existing treatment method is to carry out a large amount of water changes. The daily circulating water change volume needs to reach more than 80%, the circulation cost is relatively high, and the circulating water needs to be filtered. The filtration uses filter cotton and other materials, and the daily loss is large.
[0003] Based on the above problems, we designed a recycling ecological fish farming device that can achieve water filtration and reduce breeding costs. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a circulating ecological fish farming device which can realize water filtration and reduce the breeding cost.

[0013] The beneficial effects of the utility model are:
[0014] Advantage 1: The water in the fish pond structure only needs to maintain a small amount of circulation, and the water change rate of each fish pond only needs to be controlled at 20-30%, which extends the water change cycle and reduces the energy consumption of circulating water.
[0015] The second advantage is that the circulating water only needs to be simply filtered through an external filtering device before it can flow back. After flowing back, it is absorbed by the roots of water-loving plants and filtered through the coarse sand layer and lumps before flowing back into the fish pond structure. The natural dripping method can bring in oxygen while reducing the impact on the water body, keeping the water clear and lowering the cost of breeding.

[0029] In the above technical solution, the coarse sand layer 106 has a supporting effect on the soil layer. When water penetrates the soil layer, the amount of soil washed away by the water flow is reduced. The water seeps through the coarse sand layer 106 and then passes through the block 105, and finally flows out from the first water outlet 103. The outflowing water is a certain distance away from the water surface of the fish pond structure 1. After the water flows in, it hits the water surface and brings in air, which plays an increasing role.

[0034] When the above technical solution is in use, a pipe can be used to connect multiple adjacent fish pond structures. The pipe is connected to the water inlet 151, and water flows in the multiple fish pond structures. When the water level reaches the height of the overflow hole 131, the water flows from the overflow hole 131 into the inner tank 101.
[0035] The circulating water is the water in the fish pond structure 1 that circulates.
[0036] See also Figure 1 As shown, an overflow pipe 166 is provided at the front end of the fish pond structure near the upper position.

A flush plate 181 is provided at the rear end of the fish pond structure 1. A groove (not shown) is provided at the rear end of the fish pond structure 1. The flush plate 181 is assembled at the groove, and the joint is sealed with glue. A spray hole is provided at the end of the flush plate 181 inserted into the fish pond structure 1, and a one-way valve 191 is provided at the outer end surface of the flush plate 181.
[0039] In the above technical solution, an external pump is used to pump water at high pressure, and the water passes through the flushing plate 181 and then sprays toward the fish pond structure 1 , flushing the deposits at the bottom of the fish pond structure 1 toward the sewage pipe 161 .
[0040] See also Figure 1 and Figure 2 The flush plate 181 is arranged at a height higher than the sewage pipe 161, and the inner bottom of the fish pond structure 1 has an inclined bottom plate 199, the height of which gradually decreases forward.
[0041] The above technical solution is more helpful to flush out the sediment at the bottom of the fish pond structure 1, making it easier to clean and maintain the fish pond structure.
[0042] See also Figure 5 The sand retaining device 2 shown includes a plug 21, a baffle 22 is provided at one end of the plug 21, a retaining ring 23 is provided at the outer tube wall of the plug 21, the plug 21 is inserted into the second water outlet hole 104, the retaining ring 23 is interference fit between the second water outlet hole 104 and the plug 21, and a filter net 24 is provided on the inner wall of the plug 21.
[0043] This technical solution is mainly used to reduce the loss of coarse sand.
