Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an indoor drainage device. Background Technique

[0002] Industrialized recirculating aquaculture is a comprehensive aquaculture mode integrating modern biology, architecture, chemistry, electronics, engineering and other disciplines. It provides the best growth conditions for aquaculture organisms by artificially controlling various environmental factors, so as to achieve continuous high yield all day long. This mode has the advantages of less water consumption, small land occupation, high aquaculture density, controllable environmental conditions, high bait utilization rate, less sewage discharge and diseases, high product quality, and being not restricted by external climate conditions, so it has been widely applied and valued in modern aquaculture.

[0003] In the stage of industrialized seedling breeding, in order to improve the gonadal development level of broodstock and achieve better spawning effects, high-protein baits such as live shrimps are fed for about one week of nutritional enhancement before mating and spawning. However, shrimp shells will be left after the fish eat the shrimps. At the same time, in the seedling breeding stage, in order to ensure higher spawning and fertilization efficiency, oxytocin is injected into the broodstock to ensure the synchronization of gonadal development. However, vomiting of the fish often occurs after the injection of oxytocin. After the fish complete sperm and egg discharge, the staff separate the fish eggs and the fish, and need to drain water to lower the water level of the circulating water. The shrimp shells and vomit are easy to block the water outlet, resulting in slow water level decline and reduced operation efficiency. At the same time, fish eggs may be discharged during the drainage process. Therefore, an indoor drainage device is proposed to solve the problems that fish eggs are discharged into the drain pipe and the drainage effect is not ideal during the seedling breeding process.

Detailed implementation manner

[0020] The following further non - restrictive detailed description of the technical solution of the present utility model is made in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: An indoor drainage device, including a drain pipe 1, two fixing screws 3 are welded on both sides of the drain pipe 1, two nuts 2 are threadedly connected to the fixing screws 3, a fixed pulley 4 is installed on the fixing screws 3, and the position of the fixed pulley 4 is clamped and fixed by the two nuts 2. There are several first water outlet holes 12 on the surface of the drain pipe 1, and a first filter screen 7 is wrapped outside the first water outlet holes 12. There is a water outlet tightening band 6 above and below the first filter screen 7, and the water outlet tightening band 6 fixes the first filter screen 7 on the drain pipe 1. The first filter screen 7 can prevent fish eggs from being discharged from the first water outlet holes 12 when the water level is too high;

[0022] There are several second water outlet holes 15 on the lower surface of the drain pipe 1, a third filter screen 14 is wrapped outside the second water outlet holes 15, and a second filter screen 9 is wrapped outside the third filter screen 14. A connecting column 13 is fixedly connected between the second filter screen 9 and the third filter screen 14, a filter screen base 11 is fixed at the bottom of the second filter screen 9 and the third filter screen 14, and a water inlet tightening band 8 is provided at the top of the second filter screen 9 and the third filter screen 14. The water inlet tightening band 8 fixes the second filter screen 9 and the third filter screen 14 on the drain pipe 1;

[0023] A rope 5 is sleeved on the fixed pulley 4, one end of the rope 5 is fixedly connected with a collar 10, the collar 10 is located outside the second filter screen 9, and the collar 10 is slidably connected with the second filter screen 9;

[0024] A space is supported between the second filter screen 9 and the third filter screen 14 by the connecting column 13. The second filter screen 9 is a small - mesh filter screen, which can intercept large - caliber sundries (fish vomit and shrimp shells) in front of the second filter screen 9. The third filter screen 14 is a large - mesh filter screen with relatively dense mesh holes, which can intercept fish eggs in the water in front of the third filter screen 14 to prevent fish eggs from being discharged with the water flow. By pulling one end of the rope 5, the collar 10 will slide upward along the outside of the second filter screen 9, making it easier for the water flow to pass through the third filter screen 14 and be discharged into the drain pipe 1 through the second water outlet holes 15;

[0025] The drain pipe 1 is hollow inside, and the second water outlet hole 15 and the first water outlet hole 12 are connected through the hollow structure inside the drain pipe 1;

[0026] Working principle:

[0027] During operation, the industrialized circulating water is discharged from the drain pipe 1. When the staff separates the fish eggs and fish by draining the water after the fish lay eggs, when the circulating water first passes through the second filter screen 9, large-diameter sundries (fish vomit and shrimp shells) are intercepted in front of the second filter screen 9. Subsequently, when passing through the third filter screen 14, the fish eggs in the water are intercepted in front of the third filter screen 14 to prevent the fish eggs from being discharged with the water flow. Then the water source will be discharged from the drain pipe 1 through the second water outlet hole 15. When the water level is higher than the first water outlet hole 12, the fish eggs are intercepted in front of the first filter screen 7 by the first filter screen 7. The circulating water can also enter the drain pipe 1 from the first water outlet hole 12 for discharge. During the long-term drainage process, the second filter screen 9 may be blocked by too many large-diameter things (fish vomit and shrimp shells), affecting the drainage of the drain pipe 1. By pulling the rope 5, the collar 10 can slide upward along the outside of the second filter screen 9 to dredge the drainage channel, so that the water flow directly passes through the third filter screen 14 and flows into the drain pipe 1 from the second water outlet hole 15. Through this device, while protecting the fish eggs from being discharged during drainage, it enables the staff to better separate the fish eggs and fish.
