Abstract
Description
Technical Field
[0001] This application relates to the technical field of oxygen supply devices, and in particular to an oxygen supply device for freshwater aquaculture ponds. Background Technology
[0002] Freshwater aquaculture ponds are artificially constructed bodies of water specifically designed for the cultivation of aquatic organisms in freshwater environments. They are a key infrastructure in the freshwater aquaculture industry. These ponds are typically dug and constructed manually, and their sizes vary widely, from small ponds in family backyards used for raising a small number of ornamental or edible fish to large ponds covering several acres or even tens of acres in professional aquaculture farms. Freshwater aquaculture ponds require oxygen supply systems when in use.
[0003] Traditional oxygen supply devices for freshwater aquaculture ponds cannot provide intermittent oxygen supply, leading to excessive oxygen supply. Furthermore, the air outlets, being submerged for extended periods, are prone to clogging due to the accumulation of impurities and algae. Therefore, this application provides an oxygen supply device for freshwater aquaculture ponds to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide an oxygen supply device for freshwater aquaculture ponds to solve the problems mentioned in the background art.

[0006] Preferably, the outer ring surface of the expansion joint is slidably connected to the interior of the fixed column, and a number of sets of limiting holes are distributed at equal intervals on the outside of the expansion joint. A fastening bolt is installed on the outside of the fixed column, and one end of the fastening bolt passes through the fixed column and extends into the interior of the limiting hole.
[0007] Preferably, a drive motor is installed at one end of the inner top of the first cavity, a half gear is installed on the output shaft of the drive motor, the top of the rotating rod is rotatably connected to the inner top of the first cavity, a driven gear is installed on the outer ring surface of the rotating rod, and the half gear and the driven gear mesh with each other.
[0008] Preferably, the baffle is provided in two mirror-shaped parts, and the bottom of the baffle is tightly fitted with the air outlet.
[0009] Preferably, one end of the rotating rod extends through the fixed cylinder to its bottom, and a scraper is installed at the bottom end of the rotating rod, with the top of the scraper in close contact with the air outlet.
[0010] Preferably, a delivery pipe is installed at one external end of the oxygen supply machine, and the end of the delivery pipe away from the oxygen supply machine extends into the interior of the second cavity.
[0011] In summary, this application includes the following beneficial technical effects:
[0012] This freshwater aquaculture pond oxygen supply device allows for adjustment of the device's depth in the water. Loosening the fastening bolts allows the telescopic joint to move up and down, moving the fixed cylinder and other components to change the device's position. Once the desired depth is reached, tightening the fastening bolts inserts one end into the corresponding limiting hole, thus fixing the relative position of the telescopic joint and the fixed column and ensuring the device remains stable at the required depth. Rotating the rotating rod causes the baffle to rotate intermittently, allowing oxygen from the second cavity to be intermittently discharged from the vent for intermittent oxygen supply. The rotating rod also drives the scraper at its bottom to rotate, removing impurities, algae, and other substances that may be attached to the vent, preventing blockage and ensuring smooth oxygen discharge. This ensures the normal operation of the oxygen supply device, making it convenient and practical. Attached Figure Description

Detailed Implementation
[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.
[0019] An oxygen supply device for a freshwater aquaculture pond, referring to Figure 1 - Figure 4 The system includes a suspension plate 1, floats 2 symmetrically installed on both sides of the outer ends of the suspension plate 1, an oxygen supply machine 3 installed on the top of the suspension plate 1, a fixing column 4 installed at the bottom of the suspension plate 1, an expansion joint 5 installed at the bottom of the fixing column 4, a fixing cylinder 7 installed at the bottom of the expansion joint 5, a first cavity 8 and a second cavity 9 distributed vertically inside the fixing cylinder 7, air outlets 10 symmetrically opened at the bottom of the second cavity 9, a rotating rod 11 installed between the bottom of the first cavity 8 and the second cavity 9, and a baffle 12 installed on the outer ring surface of the rotating rod 11 at the bottom of the second cavity 9.
[0020] Reference Figure 1 - Figure 4 The outer ring surface of the expansion joint 5 is slidably connected to the interior of the fixed column 4. Several sets of limiting holes 6 are evenly distributed on the outside of the expansion joint 5. Fastening bolts 13 are installed on the outside of the fixed column 4, and one end of the fastening bolts 13 extends through the fixed column 4 and into the limiting hole 6. When it is necessary to adjust the depth of the device in the water, the fastening bolts 13 are loosened. Since the expansion joint 5 is slidably connected to the fixed column 4, the expansion joint 5 can be moved up and down, which will drive the fixed cylinder 7 and other components to move together to change the position of the device in the water. When it is moved to a suitable depth, the fastening bolts 13 are tightened so that one end is inserted into the corresponding limiting hole 6, thereby fixing the relative position of the expansion joint 5 and the fixed column 4 to ensure that the device is stable at the required depth, so as to adapt to the requirements of different aquaculture needs and water environment for dissolved oxygen layer depth.
[0021] Reference Figure 1 - Figure 4A drive motor 14 is installed at one end of the inner top of the first cavity 8. A half gear 15 is installed on the output shaft of the drive motor 14. The top of the rotating rod 11 is rotatably connected to the inner top of the first cavity 8. A driven gear 16 is installed on the outer ring surface of the rotating rod 11. The half gear 15 and the driven gear 16 mesh with each other. After the drive motor 14 starts, its output shaft drives the half gear 15 to rotate. Since the half gear 15 and the driven gear 16 mesh with each other, when the toothed part of the half gear 15 engages with the driven gear 16... When meshing, the driven gear 16 will rotate, which in turn will drive the rotating rod 11 to rotate. When the toothless part of the half gear 15 rotates to be opposite to the driven gear 16, the driven gear 16 and the rotating rod 11 stop rotating. The baffle 12 is provided with two pieces that are distributed in a mirror image. The bottom of the baffle 12 is tightly fitted with the air outlet 10. When the rotating rod 11 rotates under the action of the drive motor 14, it drives the baffle 12 to rotate intermittently, so that the oxygen inside the second cavity 9 is intermittently discharged from the air outlet 10 for intermittent oxygen supply.
[0022] Reference Figure 1 - Figure 4 One end of the rotating rod 11 extends through the fixed cylinder 7 to its bottom. A scraper 17 is installed at the bottom end of the rotating rod 11. The top of the scraper 17 is in close contact with the air outlet 10. When the rotating rod 11 rotates, it will drive the scraper 17 at its bottom end to rotate together. Since the top of the scraper 17 is in close contact with the air outlet 10, the scraper 17 can scrape off impurities, algae and other substances that may be attached around the air outlet 10 during the rotation process, preventing these substances from clogging the air outlet 10, ensuring that oxygen can be smoothly discharged from the air outlet 10, and ensuring the normal operation of the oxygen supply device.
[0023] Reference Figure 1 - Figure 4 An oxygen supply machine 3 has a delivery pipe 18 installed at one end of its exterior. The end of the delivery pipe 18 away from the oxygen supply machine 3 extends into the interior of the second cavity 9. After the oxygen supply machine 3 is started, the oxygen it generates is delivered into the interior of the second cavity 9 through the delivery pipe 18. Within the second cavity 9, the oxygen is distributed and discharged according to the state of the baffle 12 and the air outlet 10.
[0024] The implementation principle of the oxygen supply device for a freshwater aquaculture pond in this application embodiment is as follows: When using the device, firstly, the drive motor 14 is electrically connected to an external power source via a switch. The float 2 provides buoyancy to the suspension plate 1, allowing the entire device to float on the surface of the freshwater aquaculture pond. When it is necessary to adjust the depth of the device in the water, the fastening bolt 13 is loosened. Since the telescopic joint 5 is slidably connected to the fixed column 4, the telescopic joint 5 can be moved up and down, driving the fixed cylinder 7 and other components to move together and change the position of the device in the water. When it is moved to a suitable depth, the fastening bolt 13 is tightened so that one end is inserted into the corresponding limiting hole 6, thereby fixing the relative position of the telescopic joint 5 and the fixed column 4 to ensure that the device is stable at the required depth, so as to adapt to the requirements of different aquaculture needs and water environment for dissolved oxygen layer depth. The drive motor 14 is preferably of type HBS57. The drive motor 14 is started by a switch. After the drive motor 14 is started, its output shaft drives the half gear 15 to rotate. Since the half gear Half gear 15 meshes with driven gear 16. When the toothed part of half gear 15 meshes with driven gear 16, it will drive driven gear 16 to rotate, which in turn will drive rotating rod 11 to rotate. When the toothless part of half gear 15 rotates to be opposite driven gear 16, driven gear 16 and rotating rod 11 stop rotating. When rotating rod 11 rotates, it drives baffle 12 to rotate intermittently, so that oxygen in the second cavity 9 is intermittently discharged from air outlet 10 for intermittent oxygen supply. When rotating rod 11 rotates, it will drive scraper 17 at one end of its bottom to rotate together. Since the top of scraper 17 is in close contact with air outlet 10, scraper 17 can scrape off impurities, algae and other substances that may be attached around air outlet 10 during rotation, preventing these substances from blocking air outlet 10, ensuring that oxygen can be discharged smoothly from air outlet 10, and ensuring the normal operation of oxygen supply device. After oxygen supply machine 3 is started, the generated oxygen is transported to the second cavity 9 through delivery pipe 18. Oxygen is distributed and discharged in the second cavity 9 according to the state of the baffle 12 and the air outlet 10, which makes operation convenient and more practical.
