Description
Technical Field
[0001] The utility model belongs to the technical field related to aquaculture, and in particular relates to an automatic underwater oxygenation device for aquaculture. Background Art
[0002] Aquaculture has developed rapidly around the world and has become an important way to meet the growing demand for aquatic products. However, the oxygen level in the water is crucial to the health and efficiency of aquaculture. Insufficient oxygen not only affects the growth and reproduction of aquatic organisms, but may also lead to the deterioration of the ecological environment of the water. In order to solve this problem, automatic underwater oxygenation equipment for aquaculture has emerged, becoming a key tool for improving the oxygen supply of water bodies and optimizing the breeding environment. Traditional oxygenation equipment often relies on mechanical stirring or bubble generators. These devices usually require complex installation processes and also face certain challenges during equipment maintenance and operation. In order to solve these problems, modern underwater oxygenation equipment has incorporated more intelligent and efficient solutions into its design to improve its ease of use and operational stability;
[0003] The design concept of this underwater automatic oxygenation equipment for aquaculture is to optimize the configuration of the key components of the oxygenation system to achieve efficient and stable oxygenation function. The equipment includes two symmetrically arranged surface floats, and the oxygenation pump is closely integrated with the float system through a connecting frame and a mounting frame. The oxygenation pump transports the gas to the oxygenation aeration cylinder at the bottom through a metal oxygenation pipe, and the oxygenation holes inside the aeration cylinder evenly distribute the gas into the water body to achieve effective oxygenation function.
[0004] However, when the underwater automatic oxygenation equipment for aquaculture floats on the water surface to oxygenate the bottom of the water through the surface buoy, the horizontal buoy mainly increases the pull rope at the bottom, and a weight is installed at the bottom of the pull rope. The weight sinks to the bottom of the water to make the surface buoy float on the water surface. However, the underwater automatic oxygenation equipment for aquaculture will generate an upward reaction force during oxygenation, which will easily cause the underwater automatic oxygenation equipment for aquaculture to be displaced on the water, and when the water level rises significantly, the surface buoy will pull the weight upward through the buoyancy, so that the weight is separated from the bottom of the water, which will also easily cause the underwater automatic oxygenation equipment for aquaculture in the water to be displaced, and the position change will easily affect the oxygenation effect of the oxygenation equipment on the bottom of the water. Utility Model Content
[0005] The purpose of the utility model is to provide an automatic underwater oxygenation device for aquaculture, so as to solve the problem proposed in the above-mentioned background technology that when the water level rises significantly, the float on the water surface will pull the weight upward through the buoyancy, so that the weight is separated from the bottom of the water, which will easily cause the automatic underwater oxygenation device for aquaculture in the water to be displaced, and the position change will easily affect the oxygenation effect of the oxygenation device on the bottom of the water.
[0006] To achieve the above object, the present utility model provides the following technical solution: An automatic underwater aeration device for aquaculture, including a water surface floating barrel A and water surface floating barrels B symmetrically arranged behind the water surface floating barrel A. Connection grooves A are provided inside the left top ends at the centers of the water surface floating barrel A and the water surface floating barrels B, and connection grooves B are provided inside the right top ends at the centers of the water surface floating barrel A and the water surface floating barrels B. A floating barrel connecting frame A is connected in the two connection grooves A, and a floating barrel connecting frame B is connected in the two connection grooves B. Lifting and floating devices are provided on the outer walls of the middle sections at the bottoms of the floating barrel connecting frame A and the floating barrel connecting frame B;
[0007] The lifting and floating device at the bottom of the floating barrel connecting frame B includes a cement counterweight, a loop-shaped floating frame, and a rectangular support plate. The rectangular support plate is welded to the bottom of the floating barrel connecting frame B. The interior of the rectangular support plate is hollow and the opening direction is downward. A loop-shaped floating frame is inserted into the rectangular support plate, and a cement counterweight is sleeved outside the bottom end of the loop-shaped floating frame.
[0008] Preferably, the lifting and floating device further includes floating chutes and anti-detachment sliders. Floating chutes are provided inside the front and rear ends of the rectangular support plate, and anti-detachment sliders are welded to the outer walls of the front and rear ends of the top of the loop-shaped floating frame. The anti-detachment sliders are inserted into the floating chutes.
[0009] Preferably, the loop-shaped floating frame can move up and down in the rectangular support plate. The length of the floating chute is less than the length of the rectangular support plate, and the anti-detachment slider can move up and down in the floating chute.
[0010] Preferably, mounting frame grooves are provided inside the middle sections at the tops of the water surface floating barrel A and the water surface floating barrels B. A metal mounting frame is connected in the two mounting frame grooves, and an aeration pump is provided at the center of the top end of the metal mounting frame.
[0011] Preferably, the metal mounting frame, the floating barrel connecting frame A, and the floating barrel connecting frame B are fixedly connected to the water surface floating barrel A and the water surface floating barrels B through a plurality of screws. The shapes, sizes, and buoyancies of the water surface floating barrel A and the water surface floating barrels B are the same.
[0012] Preferably, the aeration pump is fixedly connected to the metal mounting frame through a flange and a plurality of screws. An air outlet is provided at the bottom end of the aeration pump, and a metal aeration pipe is connected to the bottom end of the air outlet.
[0013] Preferably, an aeration diffuser cylinder is provided at the bottom end of the metal aeration pipe. Aeration holes are densely distributed inside the circular outer wall and the upper and lower ends of the aeration diffuser cylinder.
[0014] Compared with the prior art, the present utility model provides an automatic underwater aeration device for aquaculture, having the following beneficial effects:
[0015] The utility model adds a new lifting and floating device at the bottom end of each of the two floating cylinder connecting frames of the underwater automatic oxygen increasing device for aquaculture. After the underwater automatic oxygen increasing device for aquaculture floats on the water surface through the surface floating cylinders, the cement counterweights at the bottom ends of the two lifting and floating devices sink to the bottom of the water, so that the underwater automatic oxygen increasing device for aquaculture floating on the water surface can be locked in the current position, avoiding the situation that the underwater automatic oxygen increasing device for aquaculture on the water surface floats and moves in windy and wavy weather. In this way, it can ensure that the underwater automatic oxygen increasing device for aquaculture can supply oxygen at a fixed point in the water body. Moreover, the most important function of the lifting and floating device is that when the water level rises or falls, the device can ensure that the underwater automatic oxygen increasing device for aquaculture can always float on the water surface, and there will be no situation that the underwater automatic oxygen increasing device for aquaculture is pulled and sinks into the water body due to a relatively high water level rise. In this way, it can not only ensure that the underwater automatic oxygen increasing device for aquaculture always floats at a fixed point on the water surface for fixed-point oxygen supply, but also ignore the rise and fall of the water level, and at the same time can withstand the reaction force generated during oxygenation, ensuring that it can continuously and stably oxygenate the bottom of the water.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0021] The utility model provides an automatic underwater aeration device for aquaculture as shown in Figures 1-3 Figure. The device includes a water surface floating barrel A5 and water surface floating barrels B7 symmetrically arranged at the rear side of the water surface floating barrel A5. Inside the left top ends at the centers of the water surface floating barrel A5 and the water surface floating barrels B7, there are connecting grooves A8. Inside the right top ends at the centers of the water surface floating barrel A5 and the water surface floating barrels B7, there are connecting grooves B13. A floating barrel connecting frame A6 is connected in the two connecting grooves A8, and a floating barrel connecting frame B12 is connected in the two connecting grooves B13. Inside the middle sections at the tops of the water surface floating barrel A5 and the water surface floating barrels B7, there are mounting frame grooves 11. A metal mounting frame 10 is connected in the two mounting frame grooves 11. At the center of the top end of the metal mounting frame 10, there is an aeration pump 9. The metal mounting frame 10, the floating barrel connecting frame A6, and the floating barrel connecting frame B12 are fixedly connected to the water surface floating barrel A5 and the water surface floating barrels B7 through a plurality of screws. The shapes, sizes, and buoyancies of the water surface floating barrel A5 and the water surface floating barrels B7 are the same. The aeration pump 9 is fixedly connected to the metal mounting frame 10 through a flange and a plurality of screws. At the bottom end of the aeration pump 9, there is an air outlet. At the bottom end of the air outlet, there is a metal aeration pipe 3. At the bottom end of the metal aeration pipe 3, there is an aeration diffuser 1. Inside the circular outer wall and the upper and lower ends of the aeration diffuser 1, there are densely distributed aeration holes 2. When using this automatic underwater aeration device for aquaculture, first, the water surface floating barrel A5 and the water surface floating barrels B7 connected and fixed through the floating barrel connecting frame A6, the floating barrel connecting frame B12, and the metal mounting frame 10 are placed floating on the water surface. After placement, through the lifting and floating device 4, this automatic underwater aeration device for aquaculture can be stably and firmly placed at a fixed position. At this time, the aeration diffuser 1 at the bottom end of the metal aeration pipe 3 is located inside the bottom end of the water body. Then, it is necessary to connect the aeration pump 9 to an automatic controller. After the automatic controller starts the aeration pump 9, the aeration pump 9 will blow air into the aeration diffuser 1 through the metal aeration pipe 3, and the gas will be blown into the water body through the aeration holes 2 in the aeration diffuser 1, so as to achieve the purpose of aerating the water body.
[0022] As shown in Figure 1 and Figure 3As shown, lifting and floating devices 4 are provided on the outer walls of the middle sections at the bottoms of the buoy connecting frame A6 and the buoy connecting frame B12. The lifting and floating device 4 at the bottom of the buoy connecting frame B12 includes a cement counterweight 14, a loop-shaped floating frame 15, and a rectangular support plate 16. The rectangular support plate 16 is welded to the bottom of the buoy connecting frame B12. The rectangular support plate 16 is hollow inside and has an opening facing downward. A loop-shaped floating frame 15 is inserted into the rectangular support plate 16. A cement counterweight 14 is sleeved outside the bottom end of the loop-shaped floating frame 15. The lifting and floating device 4 further includes a floating chute 17 and an anti-disengagement slider 18. Floating chutes 17 are provided inside the front and rear ends of the rectangular support plate 16. Anti-disengagement sliders 18 are welded to the outer walls of the front and rear ends of the top of the loop-shaped floating frame 15. The anti-disengagement sliders 18 are inserted into the floating chutes 17. The loop-shaped floating frame 15 can move up and down in the rectangular support plate 16. The length of the floating chute 17 is less than the length of the rectangular support plate 16. The anti-disengagement sliders 18 can move up and down in the floating chutes 17.
[0023] As Figure 1 and Figure 3 shown, when it is necessary to fix the underwater automatic aeration device for aquaculture at a fixed point on the water surface through the two lifting and floating devices 4, first, the cement counterweight 14 needs to be sleeved and fixed to the outside of the bottom end of the loop-shaped floating frame 15, and then the underwater automatic aeration device for aquaculture is normally placed on the water body. After placement, the two cement counterweights 14 will automatically sink to the bottom of the water, so that the underwater automatic aeration device for aquaculture can be placed at a fixed point. When the water level rises, the surface buoys floating on the water surface will rise synchronously. During the rising process, the rectangular support plate 16 will move upward outside the loop-shaped floating frame 15 to ensure that the surface buoys can move up and down normally on the water surface according to the water level, and at the same time, it can ensure that the cement counterweights 14 are normally sunk at the bottom of the water. The up and down movement of the loop-shaped floating frame 15 in the rectangular support plate 16 can ensure that the underwater automatic aeration device for aquaculture is fixed at a fixed point on the water surface and can also ensure that the underwater automatic aeration device for aquaculture can float normally on the water surface when the water level rises. The anti-disengagement sliders 18 at the front and rear ends of the top of the loop-shaped floating frame 15 slide in the floating chutes 17 inside the front and rear ends of the rectangular support plate 16. In this way, it can not only ensure that the loop-shaped floating frame 15 can move normally in the rectangular support plate 16, but also avoid the dislocation between the two, ensuring that the underwater automatic aeration device for aquaculture can stably perform underwater aeration at a fixed position.
[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
