Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an aquaculture oxygen supply device. Background Technique

[0002] Aquaculture is a production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. During the aquaculture process, the temperature, water quality, density and oxygen content need to be strictly controlled. Dissolved oxygen in water is the basic condition for the survival of aquatic animals. The content of dissolved oxygen is also related to the aquaculture density and yield. Dissolved oxygen can promote the rapid growth of fry and prevent the occurrence of fry bubble disease. When cultivating fry, it is also necessary to increase the oxygen content in the aquaculture pond. Except for using chemical oxygenation agents in emergency situations and scientific experiments, mechanical oxygenation is generally used for oxygen supply.

[0003] Chinese Patent Publication No. CN 214629183 U discloses an aquaculture oxygen supply device, including an oxygen blower assembly, an air outlet rod, a fastening cap, an air delivery pipe and a limiting block. One side of the limiting block is fixedly connected with a sealing gasket. A shunt pipe is fixedly connected to the surface of the air delivery pipe. The other end of the air delivery pipe and one end of the shunt pipe are both fixedly connected with a connecting seat. An air outlet seat is fixedly connected to the surface of the connecting seat. A filter screen is fixedly connected to the inside of the air outlet seat. The main advantage of the utility model is to provide an aquaculture oxygen supply device. The device provides an oxygen supply structure. When in use, the user puts the connecting seat into the aquaculture pond and starts the oxygen blower assembly to make oxygen be transported to the connecting seat through the air delivery pipe and discharged outward through the air outlet seat to supply oxygen to the water. Through the setting of the counterweight block, the connecting seat can sink to the bottom, so that the oxygen supply to the deep water area is more sufficient. At the same time, the air outlet seat is kept downward to cooperate with the filter screen to avoid blockage of the air outlet seat by particles such as silt.

[0004] However, when the utility model is actually used, the following problems exist:

[0005] 1. When the device is in use, when the air outlet seat supplies oxygen to the bottom, the telescopic rod is fixed inside the aquaculture pond through bolts to fix the position of the current air delivery pipe to avoid the displacement of the air delivery pipe by water flow. However, due to the small configuration of the air outlet seat, it is easy to move at the bottom, and it is difficult to ensure that the oxygen outlet of the air outlet seat faces upward. If the air outlet only faces the bottom, the released oxygen may be directly absorbed by the bottom water body, resulting in insufficient dissolved oxygen in the upper water body, leading to hypoxia in the upper water body. At the same time, it may disturb the bottom sediment, causing sediment and other particulate matters to suspend in the water, which will not only affect the water quality, but also may have an adverse impact on aquatic organisms, and is more likely to be blocked, increasing the difficulty and frequency of maintenance.

[0006] 2. When the device is in use, the position of the shunt pipe is adjusted by the telescopic rod. When the oxygen supply position needs to be changed, the position of the telescopic rod needs to be adjusted. Moreover, the telescopic rod is fixed on the water surface of the aquaculture pond, which will affect the use of other devices that need to move on the water surface in the aquaculture pond, reducing the practicality of the device. Summary of the Invention

[0007] (1) Technical problems to be solved

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides an aquaculture oxygen supply device, which solves the problems raised in the above-mentioned background technology:

[0009] 1. When the device is in use, when the air outlet seat supplies oxygen to the bottom, the telescopic rod is fixed inside the aquaculture pond through bolts to fix the position of the current gas transmission pipe to prevent the gas transmission pipe from moving due to water flow. However, since the air outlet seat is relatively small and prone to moving at the bottom, it is difficult to ensure that the oxygen outlet of the air outlet seat faces upward. If the air outlet only faces the bottom, the released oxygen may be directly absorbed by the bottom water body, resulting in insufficient dissolved oxygen in the upper water body, leading to hypoxia in the upper water body. At the same time, it may disturb the bottom sediment, causing sediment such as sand and silt to suspend in the water, which will not only affect the water quality, but also may have an adverse impact on aquatic organisms, and is more likely to be blocked, increasing the difficulty and frequency of maintenance.

[0010] 2. When the device is in use, the position of the shunt pipe is adjusted by the telescopic rod. When the oxygen supply position needs to be changed, the position of the telescopic rod needs to be adjusted. Moreover, the telescopic rod is fixed on the water surface of the aquaculture pond, which will affect the use of other devices that need to move on the water surface in the aquaculture pond, reducing the practicality of the device.

[0021] (III) Beneficial effects

[0022] The utility model provides an aquaculture oxygen supply device, which has the following beneficial effects:

[0023] 1.

Detailed Implementation Manner

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figures 1-3, the utility model provides a technical solution: an aquaculture oxygen supply device, including: an aerator main body 1, a control component 2 is installed on the aerator main body 1, an installation frame 3 is fixed at the bottom of the aerator main body 1, a spiral blade 4 is fixed on the left side of the aerator main body 1, a fixing component 6 is arranged on one side of the aerator main body 1 close to the spiral blade 4, and the fixing component 6 is connected to a protective cover 7. The aerator main body 1 and the protective cover 7 are connected through the fixing component 6. A connecting pipe 5 is arranged at the top left of the aerator main body 1, and an air inlet pipe 8 is threadedly connected to the connecting pipe 5. A rotating shaft is arranged on the aerator main body 1, and the inside of the rotating shaft is of a hollow structure and is communicated with the connecting pipe 5. Three groups of spiral blades 4 are fixed on the rotating shaft of the aerator main body 1, and an air outlet hole is opened in each group of spiral blades 4, and the air outlet hole is communicated with the inside of the rotating shaft on the aerator main body 1. The air inlet pipe 8 is a pipe-shaped structure made of a soft material, and a connecting head matched with the connecting pipe 5 is fixed on one side of the air inlet pipe 8. The control component 2 is electrically connected to the aerator main body 1, and the control component 2 is wirelessly connected to a control terminal;

[0035] The start of the aerator main body 1 can be controlled through the terminal. The installation frame 3 is arranged in a double-layer structure, and there is a certain height interval between the aerator main body 1 and the bottom of the installation frame 3. When the aerator main body 1 is placed in the aquaculture pond, the installation frame 3 will contact the bottom of the aquaculture pond first, reducing the disturbance of the sediment caused by the accidental movement or turnover of the device during oxygenation. After the aerator main body 1 is started, it will drive the upper spiral blade 4 to rotate through the rotating shaft. When the spiral blade 4 rotates at a high speed, a negative pressure area will be formed around it, so as to suck the air on the water surface through the air inlet pipe 8 and enter the inside of the rotating shaft through the connecting pipe 5. The inhaled air is sheared into tiny bubbles under the action of the spiral blade 4. Due to the small volume of these bubbles, they have a large surface area in contact with the water body, thereby increasing the dissolution speed of oxygen in the water. The dispersed tiny bubbles rise slowly in the water, enabling the air to fully contact and mix with the water body, thereby prolonging the time for oxygen to dissolve in the water.

[0036] Please refer to Figure 4 , a gas inlet 10 is fixed above the air inlet pipe 8, and the bottom of the gas inlet 10 is clamped on the top of a floating disk 11. A wire 9 is arranged on the right side of the aerator main body 1, and the other side of the wire 9 is connected to a distribution box 12. The distribution box 12 is fixed on an installation rod 13. The floating disk 11 is of a disk-shaped structure, and a circular installation groove is opened at the center position of the floating disk 11. The gas inlet 10 is of a funnel-shaped structure, and the bottom radius of the gas inlet 10 is larger than the radius of the installation groove on the floating disk 11. A wire passing hole through which the wire 9 passes is opened at the bottom of the distribution box 12, and the radius of the wire passing hole is larger than the radius of the wire 9;

[0037] By passing the air inlet pipe 8 and the electric wire 9 through the mounting grooves on the floating disc 11, and since the air inlet 10 has a funnel-shaped structure, the horn-shaped air inlet 10 increases the contact area of the air inlet 10, which helps the gas to flow smoothly into the air inlet pipe 8, improves the gas flow efficiency, makes the air inlet pipe 8 more firmly fixed above the floating disc 11, avoids the accidental falling of the air inlet pipe 8 into the water during the use of the device, affecting the use of the device, and the floating disc 11 facilitates the positioning of the air inlet pipe 8 and the electric wire 9. Whether in deep water or shallow water areas, the floating disc always floats on the water surface, and the lengths of the air inlet pipe 8 and the electric wire 9 in the water can be adjusted according to the depth of the aquaculture pond, reducing the obstruction of the air inlet pipe 8 and the electric wire 9 to the activities of aquatic organisms in the water body and the aquaculture device;

[0038] Embodiment 1:

[0039] Please refer to Figure 5 , the fixing component 6 includes a threaded bolt 61, a nut 62 and a fixing plate 63. The four fixing plates 63 are respectively fixed on the two sides where the aerator main body 1 and the protective cover 7 are matched, and each fixing plate 63 is provided with a groove for inserting the threaded bolt 61. By aligning the fixing plates 63 on the aerator main body 1 and the protective cover 7, inserting the two threaded bolts 61 into the fixing plates 63 on both sides, and threading the nut 62 onto the threaded bolt 61 on the other side, the aerator main body 1 and the protective cover 7 are fixed together;

[0040] Embodiment 2:

[0041] Please refer to Figure 6 , the fixing component 6 includes a card slot 64 and a buckle 65. Four groups of buckles 65 are fixed on the protective cover 7 at equal intervals, and card slots 64 corresponding to the positions of the buckles 65 are provided on the aerator main body 1. The buckles 65 are aligned with the card slots 64 and inserted into the inside, and the buckles 65 are buckled into the card slots 64 for fixing, which can realize the quick disassembly and installation of the aerator main body 1 and the protective cover 7;

[0042] Embodiment 3:

[0043] Please refer to Figure 7 , the fixing component 6 includes a threaded groove 66 and a threaded rod 67. The threaded rod 67 is fixed on the protective cover 7, and threads are uniformly arranged on the outer surface of the threaded rod 67. A threaded groove 66 matching the threaded rod 67 is provided on the aerator main body 1. The threaded connection method provides a relatively high connection strength and stability, making the connection between the aerator main body 1 and the protective cover 7 more firm, reducing loosening caused by vibration or water flow impact, and facilitating disassembly and replacement.

[0044] In the present utility model, the working steps of the device are as follows:

[0045] According to the layout and scale of the aquaculture pond, select a suitable location to place the aerator main body 1, and connect the aerator main body 1 to the power supply before use to ensure that the device can be used normally.

[0047] Pass one side of the electric wire 9 through the wire passing hole 10 at the bottom of the distribution box 12 to connect with the internal power supply, ensuring that the switch of the power supply is in the off state. Use tools to move the aerator main body 1 above the position in the aquaculture pond that needs oxygen supply, and slowly move the aerator main body 1 downward until the mounting frame 3 contacts the bottom of the aquaculture pond. Turn on the power supply of the distribution box 12 and control the start of the aerator main body 1 through the terminal. When the spiral blade 4 rotates at high speed, a negative pressure area will be formed around it, thereby sucking air through the air inlet pipe 8. The inhaled air is sheared into tiny bubbles under the action of the spiral blade 4, thus realizing oxygen supply.

[0048] Regularly maintain and clean the air outlet holes on the spiral blade 4 and the air inlet pipe 8 to ensure the normal operation of the device.
