[0002] In the process of aquaculture, it is necessary to use a variety of methods and technical means to ensure that the oxygen content in the water is sufficient and stable. Reasonable oxygenation measures and compliance with precautions can ensure the healthy growth of aquatic organisms and the stability of water quality. Currently, the most commonly used methods are mechanical oxygenation, chemical oxygenation and biological oxygenation to oxygenate the water. Mechanical oxygenation has a lower cost and a controllable oxygenation amount, so it is more widely used than other oxygenation methods.

[0003] Currently, the most commonly used mechanical oxygenation method is to connect an air pump to an oxygen supply tube, then place the air outlet end of the oxygen supply tube directly into the water, pump gas into the oxygen supply tube through the air pump, and the gas enters the water through the oxygen supply tube and is slightly soluble in water to support the survival of underwater organisms.

[0004] However, most of the existing oxygenation devices for fish farming can only provide oxygenation to local locations in the breeding area, resulting in uneven oxygenation in the breeding waters and a lack of oxygen supply to some locations, which requires the use of multiple oxygenation devices to provide multi-point oxygenation in the entire breeding area, thereby increasing work costs.

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0051] Example:

[0052] like Figures 1 to 4 As shown, the present invention provides an energy-saving oxygen-enhancing device for fish farming, comprising an oxygen supply unit and a guide assembly, the guide assembly being arranged in the farming area and guiding the movement of the oxygen supply unit, the oxygen supply unit comprising a housing 201, a mounting shell 306 being arranged at the bottom of the housing 201, an air supply assembly being arranged on the mounting shell 306, an oxygen supply shell 501 being arranged at the bottom of the mounting shell 306, the air supply assembly comprising an air inlet pipe 301 arranged on the mounting shell 306 and connected to the oxygen supply shell 501, one end of the air inlet pipe 301 extending out of the housing 201, a pipe 307 being arranged on the air inlet pipe 301, and the pipe 307 being connected to the oxygen supply device. Ventilation assemblies are arranged on opposite sides of the oxygen supply shell 501, the ventilation assemblies are connected to the air supply assemblies and the outside, the ventilation assemblies comprise a ventilating seat 505 arranged in the oxygen supply shell 501, a plurality of oxygen supply holes 506 are arranged on the ventilating seat 505, and the two ends of the oxygen supply holes 506 are respectively connected to the oxygen supply shell 501 and the outside.

[0053] When in use, the external oxygen supply device is connected to the pipeline 307. The oxygen supply device can be other oxygen supply equipment such as an air pump. The gas is supplied into the oxygen supply shell 501 through the oxygen supply device, and the gas can be discharged through the oxygen supply holes 506 provided on the oxygen supply shell 501 to increase oxygen underwater. When the gas flow rates of the two groups of oxygen supply holes 506 are the same, the entire oxygen supply unit does not move. When one group of oxygen supply holes 506 is blocked and closed or its gas flow rate is less than that of the other group of oxygen supply holes 506, the entire oxygen supply unit moves due to the thrust generated by the gas.

[0054] like Figures 2 to 4 As shown, in this embodiment, a rotatable control disk 402 is provided on the mounting shell 306, and a driving assembly is provided in the mounting shell 306. The flow of air is converted into driving the control disk 402 to rotate through the driving assembly. The driving assembly includes an impeller 304. The mounting shell 306 is provided with a mounting cavity 302 connected to the interior thereof, and the impeller 304 is provided with a mounting shaft 303. The mounting shaft 303 is rotatably arranged in the mounting cavity 302, and the blades of the impeller 304 are located in the flow channel of the oxygen flow. A first gear 305 is provided on the mounting shaft 303, and a rotatable second gear 401 is provided on the mounting shell 306. The second gear 401 is coaxially connected to the control disk 402, and the second gear 401 is meshed with the first gear 305.

[0055] The gas drives the impeller 304 to rotate during the flow in the intake pipe 301, thereby driving the first gear 305 on the impeller 304 to rotate. The first gear 305 drives the control disk 402 to rotate by meshing with the second gear 401 during the rotation. In addition, it can be understood that in some embodiments, the number of teeth of the second gear 401 is greater than that of the first gear 305, so that the first gear 305 controls the second gear 401 to move at a reduced speed when rotating, and makes it easier to control the rotation of the second gear 401, so as to achieve stable energy transmission.

[0056] like Figures 3 to 5 As shown, in this embodiment, a shielding mechanism is provided in the oxygen supply shell 501, and the rotation of the control disk 402 is converted into alternate shielding of two sets of ventilation components through the shielding mechanism. The shielding mechanism includes a mounting frame 601, two sets of shielding seats 602 and a set of driving rods 403. A support frame 502 is provided in the oxygen supply shell 501, and the middle section of the mounting frame 601 is hinged on the support frame 502. The two sets of shielding seats 602 are respectively provided at both ends of the mounting frame 601. The two sets of shielding seats 602 can alternately block the oxygen supply holes 506 on the two sets of ventilation seats 505. One end of the driving rod 403 is eccentrically hinged on the control disk 402; the other end is hinged on the mounting frame 601.

[0057] During the rotation of the control disk 402, the eccentrically hinged driving rod 403 drives the mounting frame 601 to rotate back and forth along the supporting frame 502 as a whole, so that the two groups of shielding seats 602 alternately block the oxygen supply holes 506 on the two groups of ventilation seats 505, so that the gas alternately flows out from the oxygen supply holes 506 on the two groups of ventilation seats 505, and the entire oxygen supply unit is driven to reciprocate in the breeding area, so as to fully perform a more uniform and comprehensive oxygenation work in the breeding area. A sealing gasket 507 is provided on the ventilation seat 505, and the sealing gasket 507 can be fitted with the shielding seat 602. The sealing performance of the shielding seat 602 is improved by the provision of the sealing gasket 507, so as to increase the reliability of the movement of the entire oxygen supply unit.

[0058] like Figure 1 , 2 As shown, in this embodiment, the guide assembly includes a rod member arranged in the breeding area, a guide sleeve 202 is fixedly arranged on the housing 201, the guide sleeve 202 is slidably sleeved on the rod member, a ball 203 in contact with the rod member is arranged in the guide sleeve 202, and suction cups 104 are arranged at both ends of the rod member. The rod member can be fixed in the breeding area by the suction cup 104, and the movement of the entire oxygen supply unit is guided by the cooperation between the guide sleeve 202 and the rod member, so as to avoid the oxygen supply unit from rotating and causing it to move only in a single direction, further increasing the reliability of the movement of the oxygen supply unit, and by the arrangement of the ball 203, the friction force when the guide sleeve 202 slides is effectively reduced, and the utilization rate of energy is improved.

[0059] like Figure 1 , 3 As shown in Figures 4 and 5, in this embodiment, a ventilation shell 503 is further provided at the bottom of the oxygen supply shell 501, and a plurality of ventilation grooves 504 extending along the axial direction of the ventilation shell 503 are circumferentially provided. The ventilation shell 503 is provided with an adjustment component, and the ventilation area of ​​the ventilation grooves 504 is adjusted by the adjustment component. The adjustment component includes a threaded knob 701 screwed on the ventilation shell 503, and the end of the threaded knob 701 extends into the oxygen supply shell 501. A shielding shell 702 is slidably provided on the ventilation shell 503 along its axis, and the shielding shell 702 can shield the ventilation grooves 504. The end of the threaded knob 701 is rotatably connected to the shielding shell 702.

[0060] The threaded knob 701 can be rotated to drive it to slide on the ventilation shell 503, thereby driving the shielding shell 702 to slide on the ventilation shell 503 to shield the ventilation slot 504, and its shielding range is adjustable. When the ventilation area of ​​the ventilation slot 504 is large, the gas flow through the oxygen supply hole 506 is reduced, thereby reducing the movement speed of the entire oxygen supply unit. Conversely, when the ventilation area of ​​the ventilation slot 504 is small, the gas flow through the oxygen supply hole 506 is increased, thereby increasing the movement speed of the entire oxygen supply unit. When the oxygen supply of the external oxygen supply device is constant, the larger the ventilation area of ​​the ventilation slot 504, the smaller the reciprocating distance of the entire oxygen supply unit, thereby facilitating the adjustment of the movement distance of the oxygen supply unit to adapt to breeding areas of different sizes. The rod member includes a mounting rod 101 and a telescopic rod 103. The telescopic rod 103 is slidably inserted into the mounting rod 101 along its axis. A guiding slope 102 is provided at the end of the mounting rod 101. The patented suction cup 104 is respectively provided at the ends of the mounting rod 101 and the telescopic rod 103. The telescopic rod 103 can slide in the mounting rod 101 to adjust the range of the guide channel. The ball 203 is guided by the guiding slope 102 to prevent the ball 203 from getting stuck, so that the device as a whole can be suitable for breeding fish of different sizes, thereby improving the application range of the device.

[0061] Specific usage and beneficial effects of the present invention:

[0062] When the device is in use, the mounting rod 101 and the telescopic rod 103 are fixed to the breeding area through the suction cup 104 to guide the oxygen supply unit. By supplying air to the mounting shell 306 through the air supply assembly, the gas can be discharged from the oxygen supply unit through the two sets of ventilation assemblies, and the flow of air can be converted into a driving control disk 402 to rotate through the driving assembly during the flow of the gas. The control disk 402 alternately blocks the two sets of ventilation assemblies through the shielding mechanism during the rotation. When the gas flow of one set of ventilation assemblies is greater than the gas flow of the other set of ventilation assemblies, a single-direction thrust is applied to the oxygen supply unit through the flow of the gas to drive the oxygen supply unit to slide along the guide assembly, so that the entire oxygen supply unit can be driven to slide back and forth along the guide assembly under the action of the shielding mechanism, thereby performing oxygenation work on a breeding area within a larger range. Compared with the traditional single-position oxygen supply, the device can evenly supply oxygen to the breeding area, avoid excessive oxygen supply in some positions, and prevent insufficient oxygen supply in some positions. The entire oxygen supply process fully utilizes the energy generated by the flow of gas, which can be achieved without increasing power, effectively saving the cost of oxygenation.

[0063] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments. On the basis of the present invention, some modifications or improvements can be made thereto, which is obvious to those skilled in the art.
