Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture equipment, and particularly relates to an externally mounted circulating water temporary culture system. Background Art

[0002] Since fish fry are much more fragile than adult fish, they are not suitable for cultivation in aquaculture circulating water systems. Aquaculture circulating water systems are relatively large, and the survival rate of fish fry is low if they are directly cultivated in them. It is not cost-effective to build an ultra-small circulating water system just for fish fry in terms of cost and land utilization rate. Therefore, the most common practice at present is to temporarily cultivate fish fry in buckets. Since the water in the buckets cannot circulate, manual pumping and drainage are usually used, which increases labor costs. In addition, direct water disinfection operations in buckets are likely to harm the fish fry.

[0003] Therefore, an external circulating water temporary breeding system with low cost, high survival rate and suitable for factory-scale breeding is urgently needed. Utility Model Content

[0023] Embodiment 1:

[0024] In this embodiment, an external circulating water temporary culture system, such as Figure 1 and Figure 2As shown, it includes an aquaculture circulating water pool 1 and multiple external circulating water barrels 2. Specifically, the aquaculture circulating water pool 1 is a large-scale circulating water aquaculture equipment in the prior art. The external circulating water barrel 2 is provided with a sewage collecting column 3, an inlet pipe 4 and an outlet pipe 5. A submersible pump 6 is provided in the sewage collecting column 3. The sewage collecting column 3 is used to collect fish feces and other wastes. The inlet end of the outlet pipe 5 is connected with the outlet end of the submersible pump 6 and the outlet end extends into the aquaculture circulating water pool 1. The submersible pump 6 can pump the water in the sewage collecting column 3 and the waste into the aquaculture circulating water pool 1 together. The inlet end of the inlet pipe 4 is located in the aquaculture circulating water pool 1 and the outlet end is located above the liquid surface of the external circulating water barrel 2. The inlet pipe 4 draws the water in the aquaculture circulating water pool 1 into the external circulating water barrel 2 through the siphon principle.

[0025] By adopting this structure, the water in the aquaculture circulating water pool 1 and the water in the external circulating water barrel 2 form a microcirculation through the submersible pump 6, providing a temporary environment suitable for fry farming. The size of the barrel is suitable for the growth of fry, and the circulating water in the aquaculture circulating water pool 1 is effectively utilized. The water can be disinfected in the aquaculture circulating water pool 1 and then transported to the external circulating water barrel 2, effectively reducing the negative impact of disinfection on small fry, with a higher survival rate, lower manufacturing cost, and saving manpower and material resources, making the utility model more practical.

[0026] In this embodiment, Figure 1 As shown, the above-mentioned sewage collecting column 3 is a hollow column. The above-mentioned sewage collecting column 3 is vertically arranged at the center of the above-mentioned external circulating water bucket 2. The top of the above-mentioned sewage collecting column 3 is open to allow the above-mentioned water outlet pipe 5 to pass through. The bottom of the above-mentioned sewage collecting column 3 is fixedly connected to the above-mentioned water bucket. The side wall of the above-mentioned sewage collecting column 3 is hollowed out to allow water, fish feces and other waste to enter and exit.

[0027] As an optimization, Figure 1 As shown, it also includes a filter screen 7, which is covered outside the above-mentioned sewage collecting column 3. The above-mentioned filter screen 7 can allow water and sewage such as fish feces to pass through. The above-mentioned filter screen 7 is used to block the fry, preventing the fry from entering the above-mentioned sewage collecting column 3 and being pumped into the above-mentioned aquaculture circulating water pool 1 by the above-mentioned submersible pump 6.

[0028] In this embodiment, Figure 1 As shown, a regulating valve 8 is provided at the water outlet end of the water inlet pipe 4 , and the regulating valve 8 is used to adjust the flow rate of water transported from the aquaculture circulating water pool 1 to the externally mounted circulating water barrel 2 .

[0029] As a specific implementation of this embodiment, Figure 1As shown, it also includes a mechanical liquid level float switch 9, the float of the mechanical liquid level float switch 9 floats on the liquid surface, and the plug of the mechanical liquid level float switch 9 is aligned with the water outlet end of the water inlet pipe 4. When the liquid level in the external circulating water barrel 2 rises to a set height, the float rises and causes the plug to gradually close the pipe opening of the water inlet pipe 4, thereby reducing the water inlet flow rate.

[0030] Further, such as Figure 1 As shown, it also includes an electronic liquid level switch 10 and a power supply 11. The electronic liquid level switch 10 is arranged in the above-mentioned sewage collecting column 3. The above-mentioned submersible pump 6 is electrically connected to the power supply 11 through the electronic liquid level switch 10. The above-mentioned electronic liquid level switch 10 is used to control the working state of the above-mentioned submersible pump 6 to control the drainage flow of the above-mentioned outlet pipe 5.

[0031] Specifically, Figure 3 As shown, the electronic liquid level switch 10 includes a sealed shell 12, a heavy ball 13 and a switch 14 arranged in the sealed shell 12, the inner wall of the sealed shell 12 is provided with a first contact and a second contact, one end of the switch 14 is hinged to the first contact, a spring 15 is provided between the switch 14 and the sealed shell 12, the first contact is electrically connected to the power supply 11, and the second contact is electrically connected to the submersible pump 6. When in use, the sealed shell 12 floats on the liquid surface in the sewage collecting column 3 and is connected to the inner wall of the sewage collecting column 3 through a connecting rope to limit it near a set height. When the water inflow of the external circulating water bucket 2 is greater than the water outflow, the sealed shell 12 of the electronic liquid level switch 10 is upright, and at this time the heavy ball 13 presses on the switch 14 to electrically connect the first contact and the second contact, and the submersible pump 6 is in an energized working state; when the water inflow is less than the water outflow, the mechanical liquid level float switch 9 gradually decreases, and the water intake gradually increases. After the liquid level is lower than the set height of the sealed shell 12, the sealed shell 12 of the electronic liquid level switch 10 slowly moves downward and inverts as the liquid level decreases, so that the weight ball 13 is separated from the switch 14, and the spring 15 pushes the switch 14 to disconnect the first contact and the second contact. At this time, the submersible pump 6 is powered off and stopped, and the water outlet is closed. At this time, the water inlet pipe 4 continues to take in water; when the liquid level rises to a certain height, the sealed shell 12 of the electronic liquid level switch 10 rises as the liquid level rises, so that the sealed shell 12 gradually stands upright, thereby turning on the power supply 11, and the submersible pump 6 starts working again. Therefore, as the liquid level rises and falls, the sealed shell 12 of the electronic liquid level switch 10 also reciprocates to stand upright or inverted, thereby turning on or off the submersible pump 6, so that the liquid level of the external circulating water bucket 2 is always maintained within the set range.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
