[0001] The utility model relates to the technical field of aeration devices, in particular to an aeration device for intensive aquaculture. Background Technique

[0002] Aquaculture is an activity in which humans utilize water areas available for aquaculture (including planting), and according to the ecological habits of aquaculture objects and the requirements for water area environmental conditions, apply aquaculture technologies and facilities to engage in the breeding of aquatic economic animals and plants.

[0003] In the prior art, in the aquaculture industry, it is necessary to maintain a sufficient concentration of dissolved oxygen in the water body to ensure the survival of aquatic animals and the proliferation of beneficial bacteria. During this process, an aeration device is required to keep the water body with a sufficient concentration of dissolved oxygen. The aeration devices include waterwheel aerators and spray aerators, etc.

[0004] However, when the traditional aeration device aerates the water body, its aeration range is relatively fixed and the oxygen supply depth is limited, resulting in a low dissolved oxygen content in the deep water area, which affects the normal survival of deep-water fish, and the oxygen supply is uneven. Therefore, the utility model proposes an aeration device for intensive aquaculture to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an aeration device for intensive aquaculture to solve the problems raised in the above background technique.

[0012] Preferably, the barrel sleeve is threadedly connected to the threaded end of the connecting rod, and a number of fan blades are fixedly connected to the side of the upper end of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] An oxygenation device for intensive aquaculture proposed by the present utility model limits the limiting plate through the limiting groove provided on the fixing plate. The motor drives the connecting rod to rotate.

[0024] Embodiment 2

[0025] On the basis of Embodiment 1, in order to enable the device to aerate water bodies at different depths underwater, an installation plate 2 is provided. The installation plate 2 is fixedly connected to the aeration device main body 1. An air pump 3 is fixedly installed on the installation plate 2. The air outlet end of the air pump 3 is connected to the air inlet hole of the air tank 14 through a connecting pipe. The air tank 14 is connected to the air inlet hole of the exhaust mechanism 12 through a pipe. Air is injected into the air tank 14 by the air pump 3, and then the air tank 14 injects air into the exhaust mechanism 12 through the connecting pipe. The exhaust mechanism 12 injects air into the water body through the exhaust holes 15, so as to increase the oxygen content in the water body;

[0026] The motor 4 is fixedly installed on the mounting plate 2. A connecting rod 6 is rotatably connected to the mounting plate 2. The connecting rod 6 is fixedly connected to the transmission shaft of the motor 4. The motor 4 drives the connecting rod 6 to rotate. The threaded end of the connecting rod 6 is threadedly connected to the barrel sleeve 13. The barrel sleeve 13 is fixedly connected to the exhaust mechanism 12. The connecting plate 11 is in the shape of a square plate. The connecting plate 11 is fixedly connected to the exhaust mechanism 12. A number of exhaust holes 15 are provided on the side of the exhaust mechanism 12. The exhaust mechanism 12 is fixedly connected to the barrel sleeve 13. The exhaust mechanism 12 is fixedly connected to the limiting plate 10 through the connecting plate 11. The limiting plate 10 is stuck in the limiting groove 8 opened on the fixing plate 7. The limiting plate 10 can slide along the limiting groove 8 opened on the fixing plate 7. The limiting plate 10, the connecting plate 11 and the exhaust mechanism 12 are limited by the limiting groove 8 opened on the fixing plate 7. The limiting plate 10 is in the shape of an "I"-shaped plate. The limiting plate 10 can slide along the limiting groove 8. An air tank 14 is fixedly connected to the limiting plate 10.

[0028] Embodiment Three

[0029] On the basis of Embodiment Two, a protective frame 5 is provided to prevent the fry in the water body from being accidentally injured by the device. A number of micropores are provided on the protective frame 5. The protective frame 5 is fixedly installed at the bottom of the mounting plate 2.

The water body can achieve water exchange inside and outside the protective frame 5 through the number of micropores provided on the protective frame 5. At the same time, by setting the protective frame 5, the fry can be prevented from approaching the mechanical structure on the device, avoiding the fry from being accidentally injured by the device. At the same time, by setting the protective frame 5, impurities such as waterweeds in the water can be prevented from winding around the device, thereby preventing the device from being damaged, and improving the reliability of the device.

[0030] Working principle: In actual use, the limiting plate 10 is limited through the limiting groove 8 formed on the fixing plate 7. The motor 4 drives the connecting rod 6 to rotate. Under the mutual limitation of the exhaust mechanism 12 and the barrel sleeve 13 with the limiting plate 10 and the connecting plate 11, the barrel sleeve 13 moves up and down along the connecting rod 6. The air pump 3 injects air into the air tank 14, and the air tank 14 then injects air into the exhaust mechanism 12. The exhaust mechanism 12 moves up and down with the barrel sleeve 13 to supply oxygen to the water body, enabling the device to uniformly supply oxygen to different depths in the water body, effectively improving the oxygen supply efficiency of the device, avoiding oxygen deficiency in the deep water area and thus affecting the normal survival of deep-water fish. The fan blade 9 on the connecting rod 6 rotates accordingly, stirring the water body through the fan blade 9, enabling the water body to fully contact with the air bubbles in the water, and dissolving more oxygen in the water body, further improving the oxygen supply efficiency of the device. The protective frame 5 at the bottom of the mounting plate 2 can prevent fry from approaching the mechanical structure on the device and being accidentally injured by the device, improving the reliability of the device.
