Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically a deep-water aeration device for aquaculture. Background Technology

[0002] In aquaculture, aeration equipment is usually needed to aerate fish ponds. However, most current aeration devices use fixed-depth aeration, meaning the aeration depth is usually fixed. This makes it difficult for these devices to be used in deeper fish ponds. Furthermore, due to differences in fish species or environmental factors, current aeration devices cannot be adapted to aeration adjustments at different depths, resulting in limitations in their use. Utility Model Content

[0003] To address the technical problems mentioned in the background section, this utility model provides a deep-water aeration device for aquaculture.

[0004] The technical solution of this utility model is as follows: A deep-water aeration device for aquaculture includes a float and an aeration pipe and an air guide pipe vertically disposed in the middle. The lower ends of the aeration pipe and the air guide pipe are connected by a U-shaped connecting bend. The upper end of the air guide pipe passes through the float and is connected to a blower. The outer wall of the aeration pipe located below the float is densely covered with air holes. By operating the blower, airflow can be transported to the aeration pipe through the air guide pipe and the connecting bend pipe, and then the aeration and oxygenation of the fishpond during aquaculture can be achieved through the air holes on the aeration pipe.

[0005] As the core technical concept of this utility model, the upper end of the aeration pipe is provided with an adjustment mechanism passing through the float plate. Specifically, the adjustment mechanism includes an adjustment rod that is vertically inserted into the aeration pipe from the upper end, and an adjustment drive motor that can drive the adjustment rod to move up and down. The lower end of the adjustment rod is provided with an adjustment plug whose outer diameter matches the inner diameter of the aeration pipe. Based on this structure, on the one hand, since the aeration pipe is erected in the fishpond, the aeration needs of deeper fishponds are guaranteed. On the other hand, by adjusting the action of the drive motor, the adjustment plug can be moved up and down, thereby realizing the aeration adjustment needs of different depth areas from bottom to top, which significantly improves the applicability of the aeration device.

[0006] As described above, in a preferred embodiment of a deep-water aeration device for aquaculture, to prevent the aeration device from affecting its own connection structure or the operation of the blower when aerating in a small area at a great depth, a pressure relief mechanism is also provided on one side of the connecting bend. This mechanism is designed to release the airflow when the air pressure in the air guide pipe is high.

[0007] Specifically, the pressure relief mechanism includes a pressure relief pipe with one end connected to a connecting bend, an outlet pipe connected to the middle of the pressure relief pipe, a second fixed cover at the outer end of the pressure relief pipe, and a pressure relief rod slidably passing through the middle of the second fixed cover. The pressure relief rod has a pressure relief plug at one end inside the pressure relief pipe with an outer diameter matching the inner diameter of the pressure relief pipe, and a fixing nut at the other end. The pressure relief mechanism also includes a spring between the second fixed cover and the pressure relief rod, configured to elastically push the pressure relief plug against the side of the outlet pipe near the connecting bend. Based on this structure, when the air pressure in the air duct is high, the airflow can push the pressure relief plug against the spring force, thereby releasing excess air pressure through the outlet pipe.

[0008] As a further preferred embodiment, in order to enable the pressure relief mechanism to adapt to different pressure relief requirements, the pressure relief pressure of the pressure relief mechanism is adjustable.

[0009] Specifically, an adjusting nut is provided on the outer ring of the pressure relief rod between the second fixed cover and the pressure relief plug. The spring is located between the adjusting nut and the second fixed cover. By rotating the adjusting nut, the compression of the spring between it and the second fixed cover can be adjusted, thereby adjusting the elastic force borne by the pressure relief plug and ultimately adjusting the pressure relief of the adjusting mechanism.

[0010] Preferably, in order to ensure that the pressure relief plug can move smoothly under gas pressure or spring force and to ensure the stability of the pressure relief rod's action, the spring is sleeved on the outer ring of the pressure relief rod.

[0011] The beneficial effects of this utility model are as follows: This utility model is a deep-water aeration device for aquaculture. On the one hand, since the aeration pipe is erected in the fishpond, it ensures the aeration needs of deeper fishponds. On the other hand, by adjusting the action of the drive motor, the adjusting plug can be moved up and down, thereby realizing the aeration adjustment needs of different depth areas from bottom to top, which significantly improves the applicability of the aeration device.

[0014] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0015] Example This embodiment provides a deep-water aeration device for aquaculture. (See [link]) Figure 1 The device includes a float plate 1 and an aeration pipe 2 and an air guide pipe 3 vertically disposed in the middle of the float plate 1. In some optional embodiments, floating objects may also be added to the float plate 1, which will not be elaborated here. The lower ends of the aeration pipe 2 and the air guide pipe 3 are connected by a U-shaped connecting bend 4. The upper end of the air guide pipe 3 passes through the float plate 1 and is connected to a blower (not shown in the figure). The outer wall of the aeration pipe 2 located below the float plate 1 is densely covered with air holes. Through the operation of the blower, airflow can be transported to the aeration pipe 2 through the air guide pipe 3 and the connecting bend 4, and then the aeration and oxygenation of the fish pond in the aquaculture process can be realized through the air holes on the aeration pipe 2. The structure of the aeration device (the above-mentioned deep-water aeration device for aquaculture) will be described in detail below with reference to the accompanying drawings.

[0016] In this embodiment, combined with Figure 2 As the core technical concept of this utility model, the upper end of the aeration pipe 2 passes through the float plate 1 and is provided with an adjustment mechanism 5.

[0017] Specifically, the adjustment mechanism 5 includes an adjustment rod 53 vertically inserted into the aeration pipe 2 from the upper end of the aeration pipe 2, and an adjustment drive 52 capable of driving the adjustment rod 53 to move up and down. The lower end of the adjustment rod 53 is provided with an adjustment plug 54 whose outer diameter is adapted to the inner diameter of the aeration pipe 2. Based on this structure, on the one hand, since the aeration pipe 2 is erected in the fishpond, the aeration needs of deeper fishponds are guaranteed. On the other hand, by adjusting the action of the drive 52, the adjustment plug 54 can be driven to move up and down, thereby realizing the aeration adjustment needs of different depth areas from bottom to top, which significantly improves the applicability of the aeration device. Moreover, even if the aeration area is large, the aeration work of deep water positions can still be given priority, further ensuring the practicality of the aeration device.

[0018] Furthermore, to prevent debris from falling into the aeration pipe 2, the adjustment mechanism 5 also includes a first fixed cover 51 fastened to the upper end of the aeration pipe 2. The adjustment rod 53 is vertically arranged through the middle of the first fixed cover 51. The adjustment drive 52 is fixed on the first fixed cover 51. As for the driving method of the adjustment drive 52, it can adopt a ball screw pair, gear and rack transmission or other driving methods. No further restrictions are made here.

[0019] In this embodiment, combined with Figure 3 As a preferred embodiment, in order to prevent the aeration device from affecting its own connection structure or the operation of the blower when it is working in a small area at a great depth, that is, when it is working in a small area at a relatively deep position, a pressure relief mechanism 7 is also provided on one side of the connecting bend 4. It is configured to release the airflow when the air pressure in the air guide pipe 3 is high.

[0020] Specifically, the pressure relief mechanism 7 includes a pressure relief pipe 71 that is vertically arranged and bent at the lower end and connected to the connecting bend 4. The middle part of the pressure relief pipe 71 is provided with an air outlet pipe 72 connected to it. The pressure relief mechanism 7 also includes a second fixed cover 73 located at the outer end (upper end) of the pressure relief pipe 71, and a pressure relief rod 74 that slides vertically through the middle part of the second fixed cover 73. The pressure relief rod 74 is located inside the pressure relief pipe 71. One end of the rod has a pressure relief plug 76 whose outer diameter matches the inner diameter of the pressure relief pipe 71, and the other end has a fixing nut 75. The pressure relief mechanism 7 also includes a spring 77 located between the second fixed cover 73 and the pressure relief rod 74. The spring 77 is configured to elastically push the pressure relief plug 76 against the side of the air outlet pipe 72 near the connecting bend 4. Based on this structure, when the air pressure in the air duct 3 is large, the airflow can push the pressure relief plug 76 to move against the elastic force of the spring 77, and then release the excess air force through the air outlet pipe 72.

[0021] As a further preferred embodiment, in order to enable the pressure relief mechanism 7 to adapt to different pressure relief requirements, the pressure relief pressure of the pressure relief mechanism 7 is adjustable.

[0022] Specifically, an adjusting nut 78 is provided on the outer ring of the pressure relief rod 74 between the second fixed cover 73 and the pressure relief plug 76. The spring 77 is located between the adjusting nut 78 and the second fixed cover 73. By rotating the adjusting nut 78, the compression of the spring 77 between it and the second fixed cover 73 can be adjusted, thereby adjusting the elastic force borne by the pressure relief plug 76, and finally adjusting the pressure relief of the adjusting mechanism 5.

[0023] Preferably, in order to ensure that the pressure relief plug 76 can move smoothly under gas pressure or the elastic force of the spring 77 and to ensure the stability of the pressure relief rod 74, the spring 77 is sleeved on the outer ring of the pressure relief rod 74.

[0024] In this embodiment, to facilitate the connection between the air guide pipe 3 and the air supply fan, the upper end of the air guide pipe 3 is provided with a connecting elbow 6 that can be connected to the air supply fan.
