Compared to a single oxygenation device, the dissolved oxygen efficiency is significantly improved, effectively preventing dissolved oxygen stratification in the water and providing a sufficient and uniform oxygen environment for aquaculture.

Description

Technical Field

[0001] This utility model relates to the field of oxygenation devices, and in particular to an aquaculture oxygenation device that can simulate water flow. Background Technology

[0002] In aquaculture, dissolved oxygen levels in the water are a key indicator affecting the growth and reproduction of fish, shrimp, and other aquatic organisms. When the stocking density is high or the weather changes, oxygen deficiency is likely to occur in the water. Oxygenation devices have become the core equipment to ensure aquaculture efficiency. Oxygenation devices can effectively increase dissolved oxygen concentration, prevent farmed organisms from surfacing due to oxygen deficiency, and accelerate water circulation and decomposition of harmful substances, thereby improving the water quality environment. They are an essential facility for achieving high-density healthy aquaculture in modern intensive aquaculture.

[0003] Existing aeration devices are mostly single-function devices, using only one aeration method, such as surface aeration, which is difficult to effectively increase the dissolved oxygen in the bottom water, easily causing oxygen stratification and leading to oxygen deficiency in bottom-cultured organisms. Therefore, those skilled in the art have provided an aquaculture aeration device that can simulate water flow to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aeration device for aquaculture that can simulate water flow. This device uses a dual aeration method to cover the entire area of ​​the pond. Compared with a single aeration device, the dissolved oxygen efficiency is significantly improved, effectively avoiding dissolved oxygen stratification in the water and providing a sufficient and uniform oxygen environment for aquaculture.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An aquaculture oxygenation device that can simulate water flow includes a pool, a first oxygenation mechanism installed inside the pool, a sensor module installed on the inner wall of one side of the pool, a second oxygenation mechanism installed on the inner wall of the other side of the pool, and an auxiliary mechanism installed on one side of the pool.

[0007] The first oxygenation mechanism includes an air inlet pipe and an aeration pipe. An aeration hole is provided at the upper end of the aeration pipe. The second oxygenation mechanism includes a conveying box. A first conveying pipe is fixedly installed on one side of the upper end of the conveying box, and a second conveying pipe is fixedly installed on the other side of the upper end of the conveying box. A water inlet pipe is fixedly installed on one side of the front of the conveying box, and a water outlet pipe is fixedly installed on the other side of the front of the conveying box. The auxiliary mechanism includes an auxiliary box. A filter is fixedly installed on one side of the auxiliary box, and a water pump is fixedly installed on the other side of the auxiliary box. A connecting pipe is fixedly installed at the input end of the water pump.

[0008] Furthermore, the air intake pipe is fixedly installed at the bottom of one side of the pool, and a control valve is fixedly installed on the outer surface of the air intake pipe.

[0009] Furthermore, the aeration pipe is arranged around the bottom of the water tank, and the aeration pipe is fixedly connected to the air inlet pipe through a pipeline.

[0010] Furthermore, the sensor module consists of a pH sensor, a dissolved oxygen sensor, and a temperature sensor.

[0011] Furthermore, the first delivery pipe is fixedly connected to the filter on one side.

[0012] Furthermore, one side of the connecting pipe is fixedly connected to the filter.

[0013] Furthermore, the water pump output end and the second delivery pipe are fixedly connected.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes an aeration device for aquaculture that can simulate water flow. The aeration device adopts a dual aeration mode of bottom aeration and water circulation. The first aeration mechanism injects air into the bottom of the pool in the form of microbubbles through aeration pipes and aeration holes. During the rise of the bubbles, the contact area between the water and the air is greatly increased, which rapidly increases the dissolved oxygen content of the bottom water. The second aeration mechanism works in conjunction with the auxiliary mechanism. The water pump drives the water circulation. During the flow, the water fully contacts the air to achieve natural oxygenation. At the same time, the oxygen-rich water in the upper layer is transported to the bottom. The dual aeration method covers the entire area of ​​the pool. Compared with a single aeration device, the dissolved oxygen efficiency is significantly improved, effectively avoiding the phenomenon of dissolved oxygen stratification in the water and providing a sufficient and uniform oxygen environment for aquaculture.

[0016] 2. This utility model proposes an aeration device for aquaculture that can simulate water flow. The device works in conjunction with a second aeration mechanism and an auxiliary mechanism to simulate a natural water flow environment through water pumping, filter purification, and pipeline water delivery. The circulating water flow not only promotes the movement of farmed organisms and enhances their physical condition, but also promotes the even distribution of nutrients and dissolved oxygen in the water, avoiding local water quality deterioration. In addition, the flushing effect of the water flow can reduce the deposition of uneaten feed and feces, reduce the risk of water pollution, create a stable and healthy growth environment for aquaculture, and improve aquaculture efficiency and survival rate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-5 An embodiment of this utility model is provided: an aquaculture oxygenation device that can simulate water flow, including a water tank 1, a first oxygenation mechanism 2 is provided inside the water tank 1, a sensor module 3 is provided on the inner wall of one side of the water tank 1, a second oxygenation mechanism 4 is provided on the inner wall of the other side of the water tank 1, and an auxiliary mechanism 5 is provided on one side of the water tank 1. The sensor module 3 is composed of a pH sensor, a dissolved oxygen sensor and a temperature sensor.

[0026] Specifically, pool 1 serves as the aquaculture carrier, the first oxygenation mechanism 2 is responsible for basic oxygenation, the sensor module 3 monitors the water environment parameters in real time, and the second oxygenation mechanism 4 works in conjunction with the auxiliary mechanism 5 to achieve water flow simulation and circulating oxygenation. All parts cooperate with each other to provide a stable and suitable living environment for aquaculture.

[0027] Reference Figure 1 , Figure 2 , Figure 5The first oxygenation mechanism 2 includes an air inlet pipe 201 and an aeration pipe 204. The aeration pipe 204 has an aeration hole 203 at its upper end. The air inlet pipe 201 is fixedly installed at the bottom of one side of the water tank 1. A control valve 202 is fixedly installed on the outer surface of the air inlet pipe 201. The aeration pipe 204 is arranged around the bottom of the inside of the water tank 1. The aeration pipe 204 is fixedly connected to the air inlet pipe 201 through a pipe. The second oxygenation mechanism 4 includes a conveying box 403. A first conveying pipe 401 is fixedly installed on one side of the upper end of the conveying box 403. A second conveying pipe 402 is fixedly installed on the other side of the upper end of the conveying box 403. A water inlet pipe 404 is fixedly installed on one side of the front of the conveying box 403. A water outlet pipe 405 is fixedly installed on the other side of the front of the conveying box 403. One side of the first conveying pipe 401 is fixedly connected to a filter 501.

[0028] Specifically, in the first oxygenation mechanism 2, the control valve 202 controls the gas flow rate, and the air inlet pipe 201 delivers air to the aeration pipe 204 surrounding the bottom of the pool. Tiny bubbles are released through the aeration holes 203 to oxygenate the water. In the second oxygenation mechanism 4, the first delivery pipe 401 receives the water treated by the auxiliary mechanism 5, and after passing through the delivery box 403, it is discharged from the outlet pipe 405, which promotes the circulation of water in the pool.

[0029] Reference Figure 1 , Figure 4 The auxiliary mechanism 5 includes an auxiliary box 504. A filter 501 is fixedly installed on one side inside the auxiliary box 504, and a water pump 503 is fixedly installed on the other side inside the auxiliary box 504. A connecting pipe 502 is fixedly installed at the input end of the water pump 503. One side of the connecting pipe 502 is fixedly connected to the filter 501, and the output end of the water pump 503 is fixedly connected to the second delivery pipe 402.

[0030] Specifically, in the auxiliary mechanism 5, the filter 501 purifies the water pumped from the pool, removing impurities and pollutants. The water pump 503 pumps the filtered water through the connecting pipe 502 to the second oxygenation mechanism 4 via the second delivery pipe 402, driving the water to circulate and simulate the natural water flow environment.

[0031] Working Principle: When using this aquaculture oxygenation device, the pH sensor, dissolved oxygen sensor, and temperature sensor in sensor module 3 monitor the pH, dissolved oxygen content, and temperature of the water in pool 1 in real time and transmit the data to the control system. When the dissolved oxygen sensor detects that the dissolved oxygen level in the water is lower than the set threshold, the control system activates the first oxygenation mechanism 2. Air enters the aeration pipe 204 through the air inlet pipe 201, and after the flow rate is regulated by the control valve 202, it is released into the water in the form of tiny bubbles through the aeration holes 203. As the bubbles rise, they increase the contact area between the water and the air, rapidly increasing the dissolved oxygen level. At the same time, the auxiliary mechanism 5 and the second oxygenation mechanism 4 work together to simulate natural oxygenation. The water is pumped from pool 1 into auxiliary tank 504 by water pump 503 through inlet pipe 404. The water first passes through filter 501 to remove impurities, uneaten feed, feces and other pollutants. Filter 501 uses existing PP cotton filter element. Its working principle will not be described in detail here. The purified water enters delivery box 403 through connecting pipe 502 and second delivery pipe 402, and is finally discharged from outlet pipe 405. The water flow direction and velocity of outlet pipe 405 are designed to promote the circulation of water in pool 1, so that the cultured organisms are in a flowing water environment, which promotes the movement and metabolism of the cultured organisms, and also helps to evenly distribute dissolved oxygen and nutrients in the water.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
