Description
Technical Field
[0001] The utility model relates to the technical field of swirl sewage collection devices for aquaculture, and particularly relates to a surface water swirl sewage collection device for aquaculture. Background Art
[0002] Aquaculture is a production activity of artificially controlling the reproduction, cultivation and harvesting of aquatic animals and plants. Generally, it includes the whole process of cultivating aquatic products from fry under artificial feeding and management. Broadly speaking, it can also include the enhancement of fishery resources. Aquaculture has methods such as extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put fry in medium and small natural waters and rely entirely on natural bait to grow aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive culture is to grow aquatic products by feeding and fertilizing in smaller water bodies, such as pond fish farming, cage fish farming and enclosure culture. High-density intensive culture uses methods such as flowing water, temperature control, oxygenation and feeding high-quality bait to carry out high-density culture in small water bodies, so as to obtain high yields, such as flowing water high-density fish farming, shrimp farming, etc.
[0003] At present, the water body flow and exchange in the culture pond are mainly completed through two methods: one is to drive the water body flow through aeration; the other is to use a water pump for water intake and drainage, that is, to discharge the culture wastewater with a higher pollutant concentration through the central sewage discharge hole, and then supplement the culture water with better water quality conditions. However, the driven water flow mainly shows the flow and exchange between the upper and lower water layers, and there is less water body flow and exchange in the horizontal water layer; and the water flow direction in the pond is disorderly, and at the same time, the drainage often discharges the tail water from the bottom of the culture pond, and the floating objects floating on the surface of the water body cannot effectively circulate in the water body, forming a dead corner of the water body circulation and exchange, resulting in the ineffective precipitation of the fed biomass feed and impurities. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a surface water swirl sewage collection device for aquaculture that utilizes the surface water of the culture pond and discharges the silt at the bottom of the culture pond in a swirling manner.
[0005] The technical solution adopted by the utility model is: the utility model includes a culture pond, a dual-channel sewage discharge member arranged at the bottom of the culture pond for silt discharge and water circulation, and a swirl assembly communicated with the dual-channel sewage discharge member for stirring the water body. The culture pond is provided with an aeration assembly for oxygen supply. The swirl assembly includes a booster pump communicated with the water outlet end of the dual-channel sewage discharge member, a regulating valve communicated with the output side of the booster pump for adjusting the water flow direction, a first swirl tube communicated with the first outlet of the regulating valve, and a second swirl tube communicated with the second outlet of the regulating valve. The water outlet of the first swirl tube is arranged clockwise towards the inner wall of the culture pond, and the water outlet of the second swirl tube is arranged counterclockwise towards the inner wall of the culture pond.
[0006] Further, the aeration assembly includes an air inlet pipe communicating with an external oxygenation device, a ring-shaped air pipe arranged along the outer wall of the aquaculture pond and communicating with the air inlet pipe, and a plurality of delivery pipes communicating with the ring-shaped air pipe for aeration and oxygenation. An aeration member for evenly distributing oxygen is formed at the outlet end of the delivery pipe.
[0007] Further, the dual-channel sewage discharge member includes a sewage discharge cavity fixedly connected to the bottom of the aquaculture pond, a drain pipe arranged in the middle of the sewage discharge cavity, and a sewage discharge pipe arranged at the bottom of the sewage discharge cavity and communicating with an external sludge extraction mechanism. A plurality of slots for collecting sludge are formed on the upper surface of the sewage discharge cavity, and a plurality of openings for collecting the surface water of the aquaculture pond are formed in the upper part of the drain pipe.
[0008] Further, a top cover is threadedly connected to the upper part of the drain pipe, and a water flow hole is formed in the middle of the top cover.
[0009] Further, the regulating valve includes a fixed seat, a first connection port, a second connection port and a third connection port arranged on the side of the fixed seat. The first connection port is connected to the output side of the booster pump, the second connection port is communicated with the first swirl tube, the third connection port is communicated with the second swirl tube, and a regulating member for the water flow out direction is rotatably connected to the fixed seat.
[0010] Further, the fixed seat is provided with a rotating cavity and a rotating table. The regulating member includes a regulating ball rotatably connected in the rotating cavity, a transmission rod fixedly connected to the regulating ball, and a grip fixedly connected to the transmission rod. A sliding card engaging and limiting with the rotating table is sleeved on the grip.
[0011] Further, an inclined surface is formed at the bottom of the aquaculture pond, and an opening communicating with the dual-channel sewage discharge member is formed at the bottom of the inclined surface.
[0012] The beneficial effects of the present utility model are as follows: Since the swirl assembly of the present utility model adopts the first swirl tube and the second swirl tube arranged bidirectionally, the water flow ejected from the first swirl tube or the second swirl tube forms a swirl thrust at the bottom of the water body. The water body rotates under the action of the thrust, so that the water body in the horizontal water layer flows and the water body circulation is carried out. Cooperating with the aeration member vertically extending into the aquaculture pond, the water with high oxygen content flows horizontally, making the oxygen-rich area in the aquaculture pond uniform, effectively avoiding the aggregation of fry, improving the feed feeding effect, and the swirling water body pushes the sludge deposited on the inclined surface at the bottom of the aquaculture pond to the middle sewage discharge cavity and discharges it to the outside for treatment through the sewage discharge pipe. The structure is simple and effective, and the sewage collection and discharge efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0021] Such as Figures 1 to 7As shown, in this embodiment, the utility model includes a breeding pond 1, a dual-channel sewage discharge member 3 disposed at the bottom of the breeding pond 1 for silt discharge and water circulation, and a swirl assembly 4 communicated with the dual-channel sewage discharge member 3 for agitating the water body. The breeding pond 1 is provided with an aeration assembly 2 for oxygen supply. The swirl assembly 4 includes a booster pump 41 communicated with the water outlet end of the dual-channel sewage discharge member 3, a regulating valve 42 communicated with the output side of the booster pump 41 for adjusting the water flow direction, a first swirl pipe 43 communicated with the first outlet of the regulating valve 42, and a second swirl pipe 44 communicated with the second outlet of the regulating valve 42. The water outlet of the first swirl pipe 43 is arranged clockwise towards the inner wall of the breeding pond 1, and the water outlet of the second swirl pipe 44 is arranged counterclockwise towards the inner wall of the breeding pond 1. The breeding pond 1 is circular. The dual-channel sewage discharge member 3 collects the surface water floating on the surface of the breeding pond 1 through a drain pipe 32 with a number of formed openings 35, and pushes the surface water located in the upper part of the water body to the bottom of the water body through the swirl assembly 4, which can effectively clean the impurities floating on the surface of the water body under the action of surface tension and keep the water body clean under the action of water flow. The swirl assembly 4 adopts a bidirectional setting of the first swirl pipe 43 and the second swirl pipe 44. The water flow ejected from the first swirl pipe 43 or the second swirl pipe 44 forms a swirl thrust at the bottom of the water body. The water body rotates under the action of the thrust, causing the water body in the horizontal water layer to flow and perform water body circulation. Cooperating with the aeration member 24 vertically inserted into the breeding pond 1, the water with high oxygen content flows horizontally, making the oxygen-rich area in the breeding pond 1 uniform, effectively avoiding the aggregation of fry, improving the feed feeding efficiency. The swirling water body pushes the silt deposited on the inclined surface at the bottom of the breeding pond 1 towards the central sewage chamber 31 and discharges it to the outside for treatment through the sewage pipe 33. The structure is simple and effective, improving the sewage collection and discharge efficiency.
[0022] In this embodiment, the aeration assembly 2 includes an air inlet pipe 21 communicated with an external oxygenation device, an annular air pipe 22 disposed along the outer wall of the breeding pond 1 and communicated with the air inlet pipe 21, and a number of conveying pipes 23 communicated with the annular air pipe 22 for aeration and oxygenation. The outlet end of the conveying pipe 23 is formed with an aeration member 24 for evenly distributing oxygen. The aeration member 24 can be an aeration stone, an aeration disc or a nano-aeration pipe, etc., for delivering the input oxygen into the water body in the form of dense bubbles. A plurality of conveying pipes 23 are arranged at equal intervals in the annular air pipe 22 to avoid the accumulation of fish groups caused by unilateral aeration and oxygenation, which affects the feeding effect of the fish group.
[0023] In this embodiment, the dual-path sewage discharge member 3 includes a sewage discharge chamber 31 fixedly connected to the bottom of the breeding pond 1, a drainage pipe 32 arranged in the middle of the sewage discharge chamber 31, and a sewage discharge pipe 33 arranged at the bottom of the sewage discharge chamber 31 and connected to an external sludge extraction mechanism. The upper surface of the sewage discharge chamber 31 is formed with a plurality of grooves 34 for collecting sludge, and the upper part of the drainage pipe 32 is formed with a plurality of openings 35 for collecting surface water of the breeding pond 1. The bottom of the sewage discharge chamber 31 is an arc surface, and the sludge entering the sewage discharge chamber 31 enters one side of the sewage discharge pipe 33 along the arc surface and flows out to the outside. The drainage pipe 32 is cylindrical, and the diameter of the opening 35 arranged at the upper part is smaller than the body size of the fry, thereby ensuring the surface water suction amount while effectively preventing the fry from escaping from the opening 35.
[0024] In this embodiment, a top cover 36 is threadedly connected to the upper portion of the drain pipe 32 , and a water flow hole 37 is formed in the middle of the top cover 36 . The top cover 36 is provided to facilitate workers to open and clean it when the opening 35 is blocked.
[0025] In this embodiment, the regulating valve 42 includes a fixed seat 421, a first connection port 422, a second connection port 423 and a third connection port 424 arranged on the side of the fixed seat 421, the first connection port 422 is connected to the output side of the boost pump 41, the second connection port 423 is connected to the first vortex tube 43, and the third connection port 424 is connected to the second vortex tube 44. The fixed seat 421 is rotatably connected to an adjusting member for the outflow direction of water flow. The regulating valve 42 is a three-way valve, and the flow direction of the incoming water flow is adjusted by turning the adjusting member.
[0026] In this embodiment, the fixed seat 421 is provided with a rotating chamber 426 and a rotating table 427, and the adjusting member includes an adjusting ball 425 rotatably connected to the rotating chamber 426, a transmission rod 428 fixedly connected to the adjusting ball 425, and a handle 429 fixedly connected to the transmission rod 428. The handle 429 is provided with a sliding card that is engaged and limited with the rotating table 427. Two limiting holes are provided on the rotating table 427, each of which is formed with a thread, and the limiting hole is threadedly connected to a limiting column. A limiting groove is formed on the handle 429 that is limited at 90 degrees to the limiting column. The sliding card structure enables the staff to maintain the direction of the handle 429 after completing the valve adjustment to prevent the handle 429 from rotating under non-human action and changing the water outlet direction.
[0027] In this embodiment, an inclined surface is formed at the bottom of the breeding pond 1, and an opening connected to the dual-path sewage discharge component 3 is formed at the bottom of the inclined surface. Heavy silt is naturally deposited, and the swirling water body cooperates with the inclined surface to make the silt flow toward the groove 34 of the sewage discharge chamber 31, thereby improving the cleaning efficiency of the silt.
[0028] The working principle of this utility model:
[0029] The aquaculture pond 1 is filled with aquaculture water, and the water level of the aquaculture water is within the height range of the opening 35 of the drain pipe 32;
[0030] When the staff toggles the regulating valve 42 and the regulating valve 42 is adjusted to the double-pass state, the surface water of the aquaculture water surface flows into the water inlet end of the booster pump 41 from the opening 35 of the drain pipe 32. After the booster pump 41 pressurizes the incoming surface water, it sprays out from the output side. The water flow enters the regulating valve 42 and enters the first swirl tube 43 or the second swirl tube 44 along the opening side of the regulating ball 425. The water flow sprays out unidirectionally at the bottom of the aquaculture pond 1, pushing the bottom water body to rotate to form a swirl. The bottom silt accumulates towards the side of the sewage discharge cavity 31 of the double-way sewage discharge member 3 under the action of the water swirl at the bottom. The swirling water body at the bottom drives the upper water body to rotate in the same direction, enabling the oxygen-rich water near the aeration member 24 to flow unidirectionally in the water body, making the oxygen content distribution in the water body of the aquaculture pond 1 uniform;
[0031] When the staff toggles the regulating valve 42 and the regulating valve 42 is adjusted to the three-way state, the surface water of the aquaculture water surface flows into the water inlet end of the booster pump 41 from the opening 35 of the drain pipe 32. After the booster pump 41 pressurizes the incoming surface water, it sprays out from the output side. The water flow enters the regulating valve 42 and enters the first swirl tube 43 and the second swirl tube 44 along the opening side of the regulating ball 425. The water flow sprays out in two directions at the bottom of the aquaculture pond 1, and the water flows spraying out clockwise and counterclockwise form a two-way swirl at the bottom of the aquaculture pond 1, forming a vortex at the intersection of the two swirls. The water body in the aquaculture pond 1 flows irregularly under the two swirls, enabling the oxygen-rich water near the aeration member 24 to be quickly dispersed in the water body, improving the oxygenation and aeration effect in a short time.
[0032] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
