[0001] The utility model relates to the technical field of crab seedling breeding, in particular to an oxygenation device for crab seedling breeding. Background Art

[0002] In the process of crab seed breeding, ensuring sufficient dissolved oxygen in the water is a key factor in ensuring the healthy growth of crab seedlings. Due to the large differences in the water depth of crab seed breeding ponds, how to continuously and stably provide sufficient dissolved oxygen for different water depths has become an urgent problem to be solved in the industry.

[0003] At present, the commonly used oxygenation devices in crab seedling farming mainly include air pumps, nozzles and other equipment. Although the traditional fixed oxygenation device can increase the dissolved oxygen content of the water to a certain extent, it is often unable to cover the entire water layer due to its fixed position, especially in aquaculture tanks with poor water flow. The use of fixed oxygenation devices is prone to cause hypoxia in certain areas, affecting the growth of crab seedlings.

[0004] In view of this, an oxygenation device for crab seed breeding is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to provide an oxygenation device for crab seed breeding to solve the problems raised in the above-mentioned background technology.

[0007] Furthermore, a bottom plate is fixedly mounted on the bottom end of the loading plate, and the reciprocating screw rod is rotatably mounted at a middle position of the top surface of the bottom plate.

[0008] Furthermore, a protection box is fixedly mounted on one side of the loading plate, and the first bevel gear and the second bevel gear are both located inside the protection box.

[0009] Furthermore, a limiting groove is provided on the front side of the outer wall of the loading plate, and a limiting block is integrally formed on the rear side of the movable plate, and the limiting block is slidably disposed inside the limiting groove.

[0010] Furthermore, a rotatable rotating rod is installed inside the movable plate, a front end of the rotating rod is fixedly connected to a spoiler fan, and a rear end of the spoiler fan is fixedly connected to a transmission gear.

[0011] Furthermore, a rack is fixedly mounted on the front outer wall of the loading plate, and the rack is meshed with the transmission gear.

[0012] Furthermore, the spoiler fan and the protective box are made of stainless steel.

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

[0014] By setting up a reciprocating screw, a movable plate, a spiral coil and an oxygen outlet, the device can supply oxygen to water flows at different positions to increase the uniformity of oxygenation. At the same time, by continuously starting the motor, the device can achieve dynamic oxygenation. This dynamic oxygenation method is more effective than traditional fixed oxygenation because it can cover a wider area of ​​water, avoid the formation of oxygen-deficient "dead corners", and provide crab seedlings with a more stable growth environment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-4 A oxygen enrichment device for crab seed breeding comprises an oxygen enrichment pump 1, a motor 2 and an oxygen supply pipe 8. A loading plate 3 is fixedly installed below the oxygen enrichment pump 1, a rotatable reciprocating screw 5 is arranged on one side of the loading plate 3, a movable plate 6 is threadedly connected on the outer wall of the reciprocating screw 5, an oxygen outlet 10 is arranged inside the movable plate 6, a spiral coil 9 is fixedly connected between the oxygen outlet 10 and the oxygen supply pipe 8, a second bevel gear 18 is fixedly connected to the top surface of the loading plate 3, a first bevel gear 17 is transmission-connected to one side of the motor 2, the first bevel gear 17 is meshed with the second bevel gear 18, a bottom plate 4 is fixedly installed at the bottom end of the loading plate 3, and the reciprocating screw 5 is rotatably installed in the middle position of the top surface of the bottom plate 4.

[0024] For further information, see Figure 2 A protection box 7 is fixedly installed on one side of the loading plate 3, and the first bevel gear 17 and the second bevel gear 18 are both located inside the protection box 7. By setting the protection box 7 and setting the first bevel gear 17 and the second bevel gear 18 to be located inside the protection box 7, the first bevel gear 17 and the second bevel gear 18 will not be easily disturbed by the external environment during operation, and will not easily affect the oxygen supply tube 8 and the spiral coil 9, thereby increasing the stability of the device operation.

[0025] For further information, see Figure 1 A limiting groove 14 is provided on the front side of the outer wall of the loading plate 3, and a limiting block 15 is integrally formed on the rear side of the movable plate 6. The limiting block 15 is slidably located inside the limiting groove 14. By setting the limiting groove 14 and the limiting block 15, and setting the limiting block 15 slidably located inside the limiting groove 14, the movable plate 6 is restricted by the limiting block 15 after the reciprocating screw rod 5 rotates, and cannot follow the rotation, and can only move in a predetermined direction.

[0026] During specific implementation, the user installs the device on the top of the water tank, places the loading plate 3 and the components installed on one side of the loading plate 3 into the water, and then starts the oxygen pump 1. After starting, the oxygen pump 1 will transport air to the inside of the water through the oxygen supply pipe 8, the spiral coil 9 and the oxygen outlet 10, thereby increasing the oxygen content in the water and allowing the crab seedlings to grow safely.

[0027] However, continuous oxygenation at a fixed position may result in uneven oxygenation. At this time, the user can start the motor 2 to drive the first bevel gear 17 to rotate. After the first bevel gear 17 rotates, it will drive the second bevel gear 18 meshing with it to rotate. The second bevel gear 18 is fixedly installed above the reciprocating screw 5, so the reciprocating screw 5 will also start to rotate. During the rotation of the reciprocating screw 5, the moving plate 6 will be driven by the reciprocating screw 5 to move up and down, and the oxygen outlet 10 is fixedly installed inside the moving plate 6, so the oxygen outlet 10 will also be driven to move, thereby changing the oxygenation position of the oxygen outlet 10. The presence of the spiral coil 9 enables the oxygen outlet 10 to obtain a stable oxygen supply after moving. After moving to the appropriate position, the motor 2 can be turned off. Because the position of the oxygen outlet 10 can be changed, the device can also supply oxygen to different positions, reducing the oxygenation dead corners in the water tank.

[0028] In addition, in order to increase the oxygenation effect of the device, the user can continuously start the motor 2. After the motor 2 is continuously started, the reciprocating screw 5 will also continue to rotate. After the unique thread on the surface of the reciprocating screw 5 continues to rotate, it will drive the moving plate 6 to reciprocate on the outer wall of the reciprocating screw 5. During the process, the oxygen outlet 10 will continue to oxygenate the water at different positions, further increasing the uniformity of oxygenation. At the same time, studies have shown that the oxygen utilization rate in the mobile oxygenation mode is significantly higher than that in the fixed oxygenation mode, because the movement of the device can reduce the aggregation of bubbles during the rising process, thereby improving the dispersion and dissolution efficiency of the bubbles. In the process of the moving plate 6 moving up and down, the water flow will be continuously moved. This movement can promote the circulation and mixing of the water body, which helps to reduce the stratification of the water body and make the dissolved oxygen distribution of the entire water body more uniform.

[0029] By arranging the reciprocating screw 5, the movable plate 6, the spiral coil 9 and the oxygen outlet 10, the device can supply oxygen to the water flow at different positions to increase the uniformity of oxygenation. At the same time, the device can also realize dynamic oxygenation by continuously starting the motor 2. This dynamic oxygenation method is more effective than the traditional fixed oxygenation method because it can cover a wider water area and avoid the formation of oxygen-deficient "dead corners", so that the crab seedlings have a more stable growth environment.

[0030] Embodiment 2

[0031] Based on Example 1, please refer to Figure 1-4 , an oxygen enrichment device for crab seed breeding, wherein a rotatable rotating rod 16 is installed inside the movable plate 6, the front end of the rotating rod 16 is fixedly connected to a spoiler fan 11, the rear end of the spoiler fan 11 is fixedly connected to a transmission gear 12, and a rack 13 is fixedly installed on the front outer wall of the loading plate 3, and the rack 13 is meshed with the transmission gear 12.

[0032] Furthermore, the spoiler fan 11 and the protection box 7 are made of stainless steel. By setting the spoiler fan 11 and the protection box 7 to be made of stainless steel, the spoiler fan 11 and the protection box 7 can work underwater for a longer time, thereby increasing the service life of the device.

[0033] In specific implementation, when the user continuously starts the motor 2 so that the device can have a better oxygenation effect, the movable plate 6 that reciprocates up and down will drive the transmission gear 12 to move synchronously, and the transmission gear 12 is meshed with the rack 13, and the rack 13 is fixedly installed on the front side of the loading plate 3. Therefore, in the process of the transmission gear 12 moving up and down, it will be pushed to rotate by the rack 13, thereby driving the spoiler fan 11 to rotate through the rotating rod 16, and after the spoiler fan 11 rotates, it will fully disturb the water area near the oxygen outlet 10, increase the fluidity and mixing of the water body, so that oxygen can be more evenly distributed in the water body, and improve the dissolution efficiency of oxygen.

[0034] By arranging the spoiler fan 11, the transmission gear 12, the rack 13 and the rotating rod 16, after the device continuously starts the motor 2, the rotation of the spoiler fan 11 can generate water flow, increase the fluidity and mixing property of the water body, make the oxygen more evenly distributed in the water body, and improve the dissolution efficiency of oxygen, which helps to ensure that the dissolved oxygen content in the aquaculture water body meets the needs of aquatic organisms such as crab seedlings.

[0035] In addition, the rotation of the spoiler fan 11 will form water splashes and water jumps on the water surface, forming a water curtain that can enclose air, thereby enhancing the aeration function. This not only helps to increase the surface area of ​​the gas-liquid interface, making it easier for oxygen in the air to dissolve into the water, but also helps to remove harmful gases in the water, such as ammonia, hydrogen sulfide, methane, carbon monoxide, etc.

[0036] In addition, it should be noted that the specific lengths of the loading plate 3, the reciprocating screw 5 and the spiral coil 9 are not fixed, and their lengths can be determined according to the actual needs of the user.

[0037] Working principle: The user installs the device on the top of the water tank, places the loading plate 3 and the components installed on one side of the loading plate 3 into the water, and then starts the oxygen pump 1. After starting, the oxygen pump 1 will transport air to the inside of the water through the oxygen supply pipe 8, the spiral coil 9 and the oxygen outlet 10, thereby increasing the oxygen content in the water and allowing the crab seedlings to grow safely.

[0038] However, continuous oxygenation at a fixed position may result in uneven oxygenation. At this time, the user can start the motor 2 to drive the first bevel gear 17 to rotate. After the first bevel gear 17 rotates, it will drive the second bevel gear 18 meshing with it to rotate. The second bevel gear 18 is fixedly installed above the reciprocating screw 5, so the reciprocating screw 5 will also start to rotate. During the rotation of the reciprocating screw 5, the moving plate 6 will be driven by the reciprocating screw 5 to move up and down, and the oxygen outlet 10 is fixedly installed inside the moving plate 6, so the oxygen outlet 10 will also be driven to move, thereby changing the oxygenation position of the oxygen outlet 10. The presence of the spiral coil 9 enables the oxygen outlet 10 to obtain a stable oxygen supply after moving. After moving to the appropriate position, the motor 2 can be turned off. Because the position of the oxygen outlet 10 can be changed, the device can also supply oxygen to different positions, reducing the oxygenation dead corners in the water tank.

[0039] In addition, in order to increase the oxygenation effect of the device, the user can continuously start the motor 2. After the motor 2 is continuously started, the reciprocating screw 5 will also continue to rotate. After the unique thread on the surface of the reciprocating screw 5 continues to rotate, it will drive the moving plate 6 to reciprocate on the outer wall of the reciprocating screw 5. During the process, the oxygen outlet 10 will continue to oxygenate the water at different positions, further increasing the uniformity of oxygenation. At the same time, studies have shown that the oxygen utilization rate in the mobile oxygenation mode is significantly higher than that in the fixed oxygenation mode, because the movement of the device can reduce the aggregation of bubbles during the rising process, thereby improving the dispersion and dissolution efficiency of the bubbles. In the process of the moving plate 6 moving up and down, the water flow will be continuously moved. This movement can promote the circulation and mixing of the water body, which helps to reduce the stratification of the water body and make the dissolved oxygen distribution of the entire water body more uniform.

[0040] When the user continues to start the motor 2 in order to achieve a better oxygenation effect of the device, the moving plate 6 that moves up and down will drive the transmission gear 12 to move synchronously, and the transmission gear 12 is meshed with the rack 13, and the rack 13 is fixedly installed on the front side of the loading plate 3. Therefore, during the up and down movement of the transmission gear 12, it will be pushed to rotate by the rack 13, thereby driving the spoiler fan 11 to rotate through the rotating rod 16, and after the spoiler fan 11 rotates, it will fully disturb the water area near the oxygen outlet 10, increase the fluidity and mixing of the water body, so that oxygen can be more evenly distributed in the water body, and improve the dissolution efficiency of oxygen.

[0041] By arranging the reciprocating screw 5, the movable plate 6, the spiral coil 9 and the oxygen outlet 10, the device can supply oxygen to the water flow at different positions to increase the uniformity of oxygenation. At the same time, the device can also realize dynamic oxygenation by continuously starting the motor 2. This dynamic oxygenation method is more effective than the traditional fixed oxygenation method because it can cover a wider water area and avoid the formation of oxygen-deficient "dead corners", so that the crab seedlings have a more stable growth environment.

[0042] By arranging the spoiler fan 11, the transmission gear 12, the rack 13 and the rotating rod 16, after the device continuously starts the motor 2, the rotation of the spoiler fan 11 can generate water flow, increase the fluidity and mixing property of the water body, make the oxygen more evenly distributed in the water body, and improve the dissolution efficiency of oxygen, which helps to ensure that the dissolved oxygen content in the aquaculture water body meets the needs of aquatic organisms such as crab seedlings.
