Description

Technical Field

[0001] This invention relates to the field of aquaculture, and in particular to a stable aerator and a fish tank using the aerator. Background Technology

[0002] The naturally dissolved oxygen in aquariums and other aquatic life breeding facilities is often insufficient to meet the respiration needs of aquatic organisms. Therefore, to improve the survival rate of aquatic organisms, aeration and oxygenation devices need to be installed in aquariums and other aquatic life breeding facilities. However, a single aeration and oxygenation device often cannot provide uniform oxygen supply to the entire area. The conventional method is to install multiple aeration devices to achieve saturation oxygenation. This method requires a large investment in equipment, increasing costs, and is also less aesthetically pleasing for ornamental aquariums. Therefore, an aeration device is needed that can meet the needs of multi-point aeration and is also aesthetically pleasing. Currently, there is a device that uses a water vortex ring to carry micron-sized air bubbles, which then burst at different locations in the aquarium or pond to achieve targeted oxygenation. However, during the operation of this device, protruding parts scrape across the aeration water vortex ring. Although small obstacles will not immediately cause the aeration water vortex ring to break, they still reduce the stability of the vortex ring propagation, thus reducing the propagation distance. Therefore, when the device is installed in a long aquarium or pond, the propagation range cannot be guaranteed. Summary of the Invention

[0014] The present invention provides a stable aerator and an aquarium using the aerator, which have the following beneficial effects: 1. Long-distance oxygenation: By using magnetic activation, the transmission devices of the four rupture units of this device are all concealed inside the main guide rail, with no exposed transmission components on the outside. During the propagation of the oxygenation water vortex ring, it will not encounter any obstacles except the main guide rail, thus enhancing stability. Therefore, the oxygenation water vortex ring can propagate a longer distance, enabling this invention to be applied in larger aquariums to achieve long-distance oxygenation.

[0015] 2. Good device stability: By pulling and releasing the second rope, the opening and closing support column changes from a horizontal state to a vertical state under the action of gravity before the breaker opens and closes. With the support of the bottom of the aquarium, the opening and closing support column and the support base form a stable support for the beginning and end of the main rail. When the breaker opens and closes, it will not cause significant shaking of the main rail, avoiding the occurrence of large-scale shaking of the main rail, and also reducing the oxygenation per unit time.

[0023] The curvature of the arc-shaped upper outer surface 906 on the top surface of the upper rupture 9 and the arc-shaped lower outer surface 805 on the bottom surface of the lower rupture 8 are the same as those of the main guide rail 10.

The radial surface of the second motor mounting groove 1002 has a second pull rope port slot 1003 that connects the receiving cavity containing the passive friction wheel mounting bracket 1005 to the second motor mounting groove 1002. The inner wall of the second motor mounting groove 1002 is provided with a radially arranged roller mounting pin 1001. The end of the roller mounting pin 1001 is provided with a pull rope storage roller 13 coaxially arranged therewith. The pull rope storage roller 13 is coaxially provided with a power... The second motor 12 with a reducer is connected to the end of the PLC. The control terminal of the PLC is connected to the signal terminal of the second motor 12.

[0026] When the upper fracturer 9 and the lower fracturer 8 are closed with the main guide rail 10, the diameter of the main guide rail 10 is 0.2 to 0.3 times the outlet diameter of the converging nozzle 6. When the upper fracturer 9 and the lower fracturer 8 are open with the main guide rail 10, the outer diameter of the upper fracturer 9 and the lower fracturer 8 is 0.3 to 1 times the outlet diameter of the converging nozzle 6.

[0027] Example 3 See Figure 1The present invention provides a fish tank with a stable aerator, comprising a fish tank 1, wherein the fish tank 1 includes the stable aerator of the present invention disclosed in Examples 1 to 2, and the vortex ring pushing mechanism and the vortex ring breaking mechanism are respectively located at both ends of the fish tank 1.

[0028] Working principle of the invention: Refer to Figures 1 to 11 As shown, the present invention provides a stable aerator. First, the stable aerator disclosed in Examples 1 and 2 is arranged near the bottom of the fish tank 1. The through hole on the rotating opening and closing bracket 4 is in the open state, and the rotating opening and closing plate 3 is not closed. The fracturers are located at the upper and lower ends of the main guide rail 10. The fracturers are divided into an upper fracturer 9 and a lower fracturer 8, each equipped with a top permanent magnet 902 and a bottom permanent magnet 803. The two permanent magnets have opposite magnetic poles, thus generating a magnetic force that attracts each other. This compresses the three sets of return springs 18 installed in the first contraction groove 802. Since the outer wall of the fracturer is curved, its curvature is the same as that of the main guide rail 10. Therefore, when the upper and lower fracturers are closed, they form a flat curved surface with the main guide rail 10. At this time, the first contraction groove 802 is inserted into the second contraction groove 903, and the lower limiter 801 enters the lower limiter anti-interference slot 904 and is arranged crosswise with the lower limiter anti-interference slot 904. The movable permanent magnet 17 is installed in the movable permanent magnet sliding groove 1008, and both its front and rear ends are connected to the first pull rope (not shown in the figure). The first pull rope passes through the movable permanent magnet sliding groove 1008, the first pull rope port slot 1004, and the first pull rope external track 1006 in sequence, and circles the main guide rail 10. The first pull rope is in contact with the passive friction wheel 14 and the active friction wheel 15, so that when the third motor 16 drives the active friction wheel 15 to rotate, the first pull rope will also move to cause the rupture to open and close. Similarly, one end of the second pull rope is connected to the pull rope connecting ring 704, and the other end is connected to the pull rope storage roller 13. When the second motor 12 rotates, the horizontal and vertical states of the opening and closing support 7 can be switched by retracting and extending the second pull rope.

[0029] The air pump (not shown in the figure), which is part of the vortex ring production mechanism, pumps in outside air. When the gas passes through the air chamber, it becomes micron-sized bubbles. After the micron-sized bubbles are evenly mixed with water, they enter the vortex ring pushing mechanism and flow out from the opening on the rotating opening and closing bracket 4. Then, driven by the No. 1 motor 2, the rotating opening and closing plate 3 closes the through hole on the rotating opening and closing bracket 4, so that the self-mixed micron-sized bubble water is cut off. When the cut-off water column passes through the converging nozzle 6, it curls up and generates a vortex ring. The generated vortex ring propagates in a straight line towards the vortex ring rupture mechanism.

[0030] As known from the given conditions, when the diameter of the obstacle passing through the vortex ring is less than 0.2 to 0.3 times the diameter of the vortex ring, it will not significantly affect the propagation of the vortex ring. When the size of the obstacle is greater than 0.3 times the diameter of the vortex ring, the vortex ring will rupture directly upon contact with the obstacle, similar to impacting a wall. Therefore, the four rupture devices at different positions, when closed, have a size less than 0.2 to 0.3 times the diameter of the vortex ring, and when open, a size greater than 0.3 times the diameter of the vortex ring, thus achieving targeted rupture of the vortex ring. In this invention, the diameter of the vortex ring is approximately the same as the outlet diameter of the converging nozzle 6.

[0031] Initially, the movable permanent magnet 17 is positioned closest to the rupture point on the opening / closing support 7. Since the length of the movable permanent magnet 17 is greater than the length of the rupture mounting groove 1007, it remains within the movable permanent magnet sliding groove 1008 and does not fall. Because the magnetic poles of the two permanent magnets at either end of the movable permanent magnet 17 are the same as the bottom permanent magnet 803 and the top permanent magnet 902, a repulsive force is generated, causing the lower rupture 8 and upper rupture 9 to change from a closed state to an open state. Simultaneously, the return spring 18 connecting the two changes from a compressed state to a stretched state. When the rupture opens, the PLC drives the second motor 12 to rotate, which in turn rotates the pull rope receiving roller 13, causing the second pull rope to retract. This causes the opening / closing support 7 to change from being perpendicular to the main guide rail 10 to being coaxial with it. At this point, the oxygen-enriching vortex ring passes through the front opening / closing support 7 and impacts the rupture, causing the vortex ring to break and releasing the oxygen contained within, thus achieving oxygenation at that point.

[0032] Subsequently, motor 12 rotates in the opposite direction, driving the pull rope storage roller 13 to rotate in the opposite direction, thereby releasing the pull rope. This allows the opening and closing support 7 to naturally lower under the gravity of the counterweight structure and eventually become perpendicular to the bottom of the fish tank 1, changing from being coaxial with the main guide rail 10 to being perpendicular to the main guide rail 10. Then, motor 16 drives the active friction wheel 15 to rotate and drives the passive friction wheel 14 in contact with it to move, and drives the pull rope 1 to move around the main guide rail 10, causing the moving permanent magnet 17 to move away from the opening and closing support 7. Since there is no repulsive force at this time, and the lower breaker 8 and the upper breaker 9 are a certain distance apart, the magnetic attraction is weak. Therefore, the return spring 18 returns from the stretched state to the natural state. When the distance gets closer, the magnetic force of the bottom permanent magnet 803 and the top permanent magnet 902 increases, compressing the return spring 18 and changing it from the natural state to the compressed state, thus completing one cycle.

[0033] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
