Description

Technical Field

[0001] The invention relates to the technical field of pool water oxygenation, and in particular to pool water oxygenation equipment for aquaculture. Background Art

[0002] Pool water aeration equipment is used to increase the dissolved oxygen content in water bodies such as ponds, aquariums, and aquaculture tanks. Oxygenation is important because dissolved oxygen in water is crucial for the respiration and metabolism of aquatic organisms. Sufficient dissolved oxygen maintains the ecological balance and biological health of the water. Pool water aeration equipment includes an aerator: This injects air into the water, creating bubbles and increasing the air-liquid contact area, thereby promoting the dissolution of oxygen. Common aeration devices include air pumps and aeration stones. Air pumps generate bubbles using compressed air, while aeration stones release bubbles through porous stone. Other aeration systems include underwater aerators, spray aerators, and dissolved oxygen machines.

[0003] The aeration rate of most aeration devices in the prior art is not adjustable. Different fish are located in different positions in the water and require different amounts of gas. The size of the bubbles generated is relatively uniform, resulting in the bubbles not being evenly distributed in the pool water. The unadjustable aeration rate affects the growth of fish and reduces the oxygen supply effect. At the same time, the aeration holes of the aeration devices in the prior art are easily clogged when working in water, resulting in poor aeration effect of the aeration devices.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example: Refer to Figures 1 to 8 The aquaculture pond water oxygenation equipment shown includes a connecting block 1, a shell 2 installed on the connecting block 1, an air inlet pipe 3 connected to the middle of the shell 2, and air holes 7 evenly distributed on the shell 2. An adjustment component 8 is provided at the position of the air hole 7 inside the shell 2. The adjustment component 8 includes a first mounting groove 86 opened inside the connecting block 1. The inner side surface of the first mounting groove 86 is rotatably connected to a reciprocating screw 87. One end of the reciprocating screw 87 is connected to the output shaft of the motor. The side surface of the reciprocating screw 87 is threadedly connected to a sliding block 88. The sliding block 88 is slidably connected to the first mounting groove 86 through a slide groove and a slider. An annular capsule 81 is installed inside the air hole 7. An annular groove 82 is opened at a position near the annular capsule 81 inside the shell 2. Each annular groove 82 is connected to each other, and the annular groove 82 is connected to the annular capsule 81 through a connecting groove 83. The inner side surface of the first mounting groove 86 is connected to a first connecting hole 85, and the annular groove 82 is connected to the first connecting hole 85 through a connecting groove 84.

[0030] Reference Figure 1The top surface of the connecting block 1 is connected with evenly distributed spheres 4, and the top of the spheres 4 is connected with a water inlet 5. When the device needs to be placed at a preset position in the water, first move the connecting block 1 to the preset position on the water surface, and then open the water inlet 5 in turn to add water to the inside of each sphere 4. It is worth noting that, by designing the volume of the spheres 4, it is ensured that after the water is added, the amount of water in the spheres 4 on the right is greater than the amount of water in the spheres 4 on the left. After adding the outside, under the left and right of the water gravity, the connecting block 1 and the shell 2 are tilted in the water. Under the action of gravity, the connecting block 1 and the shell 2 gradually move downward in the water until the connecting block 1 and the shell 2 move to the required position. Through the above arrangement, the connecting block 1 and the shell 2 are tilted downward, reducing the water resistance when the connecting block 1 and the shell 2 move, and facilitating the installation or removal of the connecting block 1 and the shell 2.

[0031] Reference Figure 5 and Figure 8 A second mounting groove 15 is provided inside the connecting block 1 at a position corresponding to the sphere 4. A partition 16 is fixedly connected to the middle of the second mounting groove 15. An I-shaped block 17 is slidably connected to the position of the partition 16. The I-shaped block 17 is elastically connected to the second mounting groove 15. The left edge of the inner bottom surface of the second mounting groove 15 is penetrated and connected with evenly distributed water inlets 19. The inner bottom surface of the second mounting groove 15 is penetrated and connected to the left side of the partition 16 with a fourth connecting pipe 18. The end of the fourth connecting pipe 18 away from the second mounting groove 15 extends to a position near the air intake pipe 3 and is penetrated and connected to the air intake pipe 3. A pressure relief valve 20 is connected to the side of the air intake pipe 3 near the lower part of the fourth connecting pipe 18.

[0032] After the above work is completed, gas is introduced into the interior of the air intake pipe 3. The gas inside the air intake pipe 3 first enters the interior of the second mounting groove 15 through the fourth connecting pipe 18 to squeeze the I-shaped block 17. The squeezing force causes the I-shaped block 17 to overcome the elastic force of the second mounting groove 15 and move to the right. During the movement of the I-shaped block 17, the volume of the cavity between the left side of the I-shaped block 17 and the second mounting groove 15 gradually increases, and the external water enters the interior of the second mounting groove 15 through the water inlet 19, increasing the amount of water inside the connecting block 1, that is, increasing the weight of the connecting block 1, ensuring the stability of the connecting block 1 when working in water. It is worth noting that by placing the connecting block 1 in water and then increasing the weight of the connecting block 1, the weight of the connecting block 1 is reduced during installation or removal, which facilitates the installation or removal of the connecting block 1 and the shell 2. Furthermore, by setting the amount of water entering the second installation groove 15 on the left side of the connecting block 1 to be greater than the amount of water entering on the right side, the weight balance of the left and right sides of the connecting block 1 is ensured. That is, when the water is added, under the action of the gravity of the water, the connecting block 1 will deflect and return to a horizontal state, thereby ensuring the subsequent working effect of the connecting block 1 and the shell 2.

[0033] When the I-block 17 is moved into place, the amount of gas inside the air intake pipe 3 is gradually increased, and the air pressure inside the air intake pipe 3 is gradually increased. When the air pressure exceeds the preset threshold of the pressure relief valve 20, the gas inside the air intake pipe 3 enters the interior of the shell 2 through the connecting tube 9 and the through hole 10, and then enters the water through the air hole 7 on the shell 2 to generate bubbles and exert an oxygenation effect.

[0034] The reciprocating screw 87 is then driven to rotate by the motor. When the reciprocating screw 87 rotates, it drives the sliding block 88 to move to the left inside the first mounting groove 86 to squeeze the gas inside the first mounting groove 86. The squeezing force causes the gas inside the first mounting groove 86 to enter the interior of the connecting groove 84 through the first connecting hole 85, and then enter the interior of the annular groove 82 through the connecting groove 84, and then enter the interior of each annular capsule 81 through the connecting groove 83. After the gas enters the interior of the annular capsule 81, the annular capsule 81 expands radially, and the inner diameter of the air hole on the air hole 7 gradually decreases. It is worth noting that the reciprocating screw 87 is a mechanical transmission device used to convert rotational motion into reciprocating motion. It consists of a spiral screw and a nut. When the screw rotates, the nut moves axially along the thread of the screw. This relative motion produces a reciprocating motion, which can be used to achieve linear propulsion or pulling of other parts. This is prior art and will not be described in detail here. When the sliding block 88 moves to the right on the surface of the reciprocating screw 87, the gas inside the annular capsule 81 returns to the inside of the first mounting groove 86, and the cycle repeats, constantly changing the inner diameter of the air hole 7. Since the inner diameter of the air hole 7 is directly related to the diameter of the bubbles generated in the pool water when the gas is discharged, the smaller the diameter of the air hole 7, the smaller the diameter of the bubble formed, and thus bubbles of different sizes can be generated when the above mechanism is working. The speed at which bubbles of different sizes rise in the pool water is different, and the oxygen in bubbles of different sizes The dissolution rate of the gas in the pool water is different, so that when the oxygenation device is working, there will be bubbles in different depths of the pool water, so that fish living in the pool water at different depths can quickly obtain dissolved oxygen. If the gas is discharged through the air holes 7, the size of the bubbles generated is basically the same. If the bubbles are too small, the bubbles generated will be dissolved at the bottom of the pool water, resulting in the fish in the upper layer of the pool water not being able to quickly obtain dissolved oxygen. If the bubbles are too large, although the bubbles generated will not dissolve quickly in the pool water, they can move upward from the bottom of the pool water, but the dissolution rate is too slow, resulting in the fish in the pool water not being able to quickly obtain dissolved oxygen. The surface layer of the water is where fish often stay and breathe. By generating large bubbles for oxygenation, a larger bubble belt can be formed on the surface of the water, providing more breathing space for fish.

[0035] The inner diameter of the pore 7 is changed by the reciprocating expansion of the annular capsule 81 . During the reciprocating expansion of the annular capsule 81 , the inner diameter of the pore 7 can be changed, thereby reducing the possibility of the pore 7 being blocked.

[0036] By setting up the movable plate 814, during the reciprocating expansion of the annular sac 81, the impurities originally blocked inside the air hole 7 will fall into the interior of the shell 2, and then fall onto the movable plate 814, and fall to the bottom of the shell 2 through the conical part on the movable plate 814. The conical design reduces the risk of the collected impurities moving up and down inside the shell 2 under the action of gas and causing the air hole 7 to be blocked again.

[0037] Reference Figure 2 When the sliding block 88 moves inside the first mounting groove 86, the gas inside the buffer airbag 89 can enter the right side of the first mounting groove 86 through the first connecting pipe 810, ensuring the normal movement of the sliding block 88.

[0038] The adjustment assembly 8 further includes a buffer airbag 89 connected to the interior of the connecting block 1 near the sliding block 88 . The buffer airbag 89 is communicated with the first mounting groove 86 via a first connecting pipe 810 .

[0039] Reference Figure 6 Two movable plates 814 are symmetrically connected to the middle of the annular side surface of the shell 2 through hinges, and the inner side surface of the movable plate 814 is conical.

[0040] Reference Figure 2 The inner bottom surface of the shell 2 is connected to the position of the movable plate 814, and the piston cylinder 816 is elastically and slidably connected to the piston rod 815 inside. The piston rod 815 is connected to the movable plate 814, and the piston cylinder 816 is connected to the buffer airbag 89 through a third connecting tube 817.

[0041] When the gas inside the buffer airbag 89 enters the first mounting groove 86, the gas inside the piston cylinder 816 also enters the buffer airbag 89 through the third connecting tube 817, and the air pressure inside the piston cylinder 816 decreases. Under the action of the air pressure, the piston rod 815 drives the movable plate 814 to overcome the elastic force between it and the piston cylinder 816 and move. When the gas returns to the inside of the buffer airbag 89, the gas inside the buffer airbag 89 returns to the inside of the piston cylinder 816, and then drives the movable plate 814 to move up and down. When the movable plate 814 moves up and down, it shakes, which speeds up the falling speed of impurities on the movable plate 814, thereby increasing the collection effect of impurities.

[0042] Reference Figure 2 An annular airbag 811 is installed at the lower part of the annular inner side surface of the connecting block 1, and the annular airbag 811 is connected to the first connecting hole 85 through a second connecting pipe 812.

[0043] By setting the annular airbag 811, when some of the air holes 7 are blocked, that is, the annular bag body 81 cannot expand, the gas inside the first mounting groove 86 can enter the internal cache of the annular airbag 811 through the second connecting tube 812, ensuring the normal movement of the sliding block 88. The elastic force of the second connecting tube 812 is greater than the elastic force of the annular airbag 811, and the above effect can be achieved by designing materials, etc.

[0044] Reference Figure 4 Two inclined blocks 813 are symmetrically connected to the inner side of the connecting groove 83. The inclined blocks 813 are inclined toward the direction of the annular capsule 81, which reduces the speed at which the gas inside the annular capsule 81 returns to the annular groove 82, thereby controlling the speed at which the annular capsule 81 returns to its original state, further improving the working effect when generating bubbles of different sizes.

[0045] Reference Figure 7 , the top of the shell 2 is rotatably connected to the outside of the air inlet pipe 3 with a connecting cylinder 9, the air inlet pipe 3 and the connecting cylinder 9 are rotatably connected, and the annular inner side surface of the connecting cylinder 9 is provided with evenly distributed through holes 10, and the inner bottom surface of the shell 2 is connected to the position of the connecting cylinder 9 with a mounting cylinder 11, and the inner top surface of the mounting cylinder 11 is rotatably connected with a rotating rod 12, and the upper part of the rotating rod 12 is fixedly connected to the connecting cylinder 9, and the side of the rotating rod 12 is threadedly connected to a pressure block 13, which is elastically connected to the mounting cylinder 11, and a second connecting hole 14 is opened through the inner bottom surface of the connecting cylinder 9, and the mounting cylinder 11 and the connecting cylinder 9 are connected through the second connecting hole 14, and the side of the connecting cylinder 9 corresponds to the position of the top surface of the shell 2. There are two cleaning plates 21 symmetrically connected. When the number of clogged air holes 7 is large, the gas entering the shell 2 cannot be discharged in time, the air pressure inside the air inlet pipe 3 increases, and the gas squeezes the pressure block 13. The squeezing force causes the pressure block 13 to overcome the elastic force between the pressure block 13 and the mounting cylinder 11 and move on the side of the rotating rod 12. Since the pressure block 13 is threadedly connected to the mounting cylinder 11 and the gap of the thread groove at the threaded connection is large, it is convenient to convert the squeezing force into rotational force, that is, when the pressure block 13 moves, it will drive the rotating rod 12 to rotate, and the rotating rod 12 drives the connecting cylinder 9 and the cleaning plate 21 to rotate. When the cleaning plate 21 rotates, it cleans the impurities on the shell 2, further improving the working effect of the above-mentioned equipment.

[0046] Reference Figure 5 The upper part of the cleaning plate 21 is arc-shaped, which reduces the resistance of the water flow to its surface and ensures the rotation cleaning effect of the cleaning plate 21.
