Description

Technical Field

[0001] This utility model relates to an oxygenation device, specifically, a stratified oxygenation device for lake water purification. Background Technology

[0002] Seasonal laminar flows and temporary thermolaminar flows in lakes can cause nutrients accumulated in the water to flow into the interior, leading to eutrophication and exacerbating biological pollution. Laminar flows also create temperature inversions, isolating the surface and bottom waters. The lower waters become anoxic, and reduction reactions slowly decompose organic matter. In anoxic conditions, microorganisms proliferate, further deteriorating the lake's environment. To purify the lake and increase oxygen levels, aeration equipment is typically placed in the lake. The main function of aeration equipment is... The goal is to increase the oxygen content in the water to ensure that fish do not suffer from oxygen deficiency, while also inhibiting the growth of anaerobic bacteria and preventing water deterioration that could threaten the fish's habitat. Existing aeration equipment typically uses impellers to stir up the lake water, exposing it to the air and increasing oxygen levels. However, this equipment only stirs up the surface water and does not significantly increase the oxygen content in the lower layers. Therefore, we propose a stratified aeration device for lake water purification. Utility Model Content

[0003] The purpose of this invention is to provide a stratified oxygenation device for lake water purification, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, one of the objectives of this utility model is to provide a stratified oxygenation device for lake water purification, including a mounting base. A floating box is fixedly mounted on the upper surface of the mounting base, allowing the mounting base to float on the lake surface. A tossing mechanism is provided on the mounting base, which tosses the lake water to both sides of the mounting base. The tossing mechanism includes two rotating shafts rotatably connected inside the mounting base, with both ends of the rotating shafts extending to the outer side of the mounting base. A plurality of deflectors are fixedly arranged in a circular array on the outer surface of the rotating shafts. The rotating shafts drive the deflectors to rotate and agitate the lake water. A flow guiding mechanism is provided below the mounting base, which guides the lake water at the bottom layer to flow towards the mounting base. A driving mechanism is provided inside the mounting base, which drives the tossing mechanism and the flow guiding mechanism to work.

[0005] As a further improvement to this technical solution, the flow guiding mechanism includes a transmission rod rotatably connected to the mounting base near the bottom. The lower end of the transmission rod extends to the outside of the mounting base. A rotating rod is provided on the lower side of the transmission rod. The bottom of the transmission rod and the top of the rotating rod are hinged together by a connecting rod, and both ends of the connecting rod extend out of the outside of the transmission rod. Several flow guiding plates are fixedly provided on the rotating rod, arranged linearly along the axis of the rotating rod. One end of the flow guiding plate is inclined towards the mounting base.

[0006] As a further improvement to this technical solution, the drive mechanism includes a worm gear rotatably connected to the mounting base near the bottom. The worm gear is located between the rotating shaft and the transmission rod. The threads at both ends of the worm gear are in opposite directions. A worm wheel is coaxially fixed on the rotating shaft near the worm gear. The worm wheel meshes with the worm gear. When the worm gear rotates, it drives the rotating shaft to rotate through the worm wheel.

[0007] As a further improvement to this technical solution, a transmission bevel gear is coaxially fixedly mounted on the worm gear, and a driven bevel gear is coaxially fixedly mounted on one end of the transmission rod located inside the mounting base. The driven bevel gear and the transmission bevel gear mesh with each other, and the worm gear drives the transmission rod to rotate through the transmission bevel gear and the driven bevel gear when it rotates.

[0008] As a further improvement to this technical solution, a compression spring and a limiting ring are coaxially sleeved on the outside of the transmission rod. The two ends of the compression spring are respectively fixedly installed on the top of the transmission rod and the limiting ring. When the compression spring is in a compressed state and relaxes, it pushes the limiting ring to move closer to the connecting rod. The connecting rod is used to block the movement of the limiting ring.

[0009] As a further improvement to this technical solution, a motor is fixedly installed inside the mounting base, and the output shaft of the motor is coaxially connected to one end of the worm gear through a coupling.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This lake water purification stratified oxygenation equipment uses a stirring mechanism to agitate the upper layer of lake water. During the operation of the stirring mechanism, the lake water is pushed towards both sides of the mounting base. At the same time, a guiding mechanism guides the lake water from the bottom layer to the upper layer, replenishing the area where the stirring mechanism has displaced the lake water. This creates a circulating flow between the bottom and upper layers of the lake water, effectively increasing the oxygen content and oxygenation efficiency. Furthermore, the stirring mechanism generates a pushing force on the mounting base from both sides towards each other, ensuring even force distribution and minimizing the shaking amplitude of the mounting base during operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-6As shown, one of the objectives of this embodiment is to provide a stratified oxygenation device for lake water purification, including a mounting base 1. A floating box 11 is fixedly installed on the upper surface of the mounting base 1. An air inflator is fixedly installed on the top of the floating box 11, and a sealing cap is threadedly sealed at the top of the air inflator. The floating box 11 makes the mounting base 1 float on the lake surface. A tossing mechanism 2 is provided on the mounting base 1. The tossing mechanism 2 moves the lake water to both sides of the mounting base 1. The lake water leaves the lake surface and flies into the air under the tossing of the tossing mechanism 2. At the same time, oxygen in the air enters the water to oxygenate it. The oxygenated water falls back into the lake to oxygenate the lake water. The tossing mechanism 2 includes two rotating shafts 21 rotatably connected inside the mounting base 1. The two ends of the rotating shafts 21 extend to the outside of the mounting base 1. Several tossing plates 22 are fixedly arranged in a ring array on the outer surface of the rotating shafts 21 located on the outer side of the mounting base 1. The rotating shafts 21 drive the tossing plates 22 to rotate and ripple the lake water.

[0025] The staff unscrewed the sealing cap to open the inflation tube. Then, the staff used an air pump to fill the floating box 11 with gas through the inflation tube. After inflation, the staff sealed the inflation tube with the sealing cap. Then, the staff placed the mounting base 1 into the lake. Under the buoyancy of the floating box 11, the mounting base 1 floated in the lake. At this time, the two rotating shafts 21 on the mounting base 1 drove the deflector 22 to rotate in opposite directions. The rotating deflector 22 pushed the lake water to both sides of the mounting base 1, thus raising the lake water to come into contact with the air. The oxygen in the air entered the water to oxygenate the lake water. At the same time, when the deflector 22 pushed the lake water to both sides of the mounting base 1, the reaction force of the lake water generated an inward pushing force on the mounting base 1 through the deflector 22, so that the mounting base 1 was subjected to uniform force, preventing the mounting base 1 from being subjected to large force on one side, thereby reducing the swaying amplitude of the mounting base 1 during use and improving the stability of the mounting base 1.

[0026] To facilitate oxygenation of the bottom lake water, a flow guiding mechanism 3 is installed below the mounting base 1. The flow guiding mechanism 3 guides the bottom lake water to flow towards the mounting base 1. The flow guiding mechanism 3 includes a transmission rod 31 rotatably connected to the mounting base 1 near the bottom. The lower end of the transmission rod 31 extends to the outside of the mounting base 1. A rotating rod 32 is installed on the lower side of the transmission rod 31. The bottom of the transmission rod 31 and the top of the rotating rod 32 are hinged together by a connecting rod, and both ends of the connecting rod extend outward from the transmission rod 31. Several flow guiding plates 33 are fixedly installed on the rotating rod 32, arranged linearly along the axis of the rotating rod 32. One end of the flow guiding plate 33 faces towards the mounting base 1. The seat 1 is tilted, and when the transmission rod 31 rotates, it drives the rotating rod 32 to rotate through the connecting rod. The rotating rod 32 drives the guide plate 33 to rotate. During the rotation of the guide plate 33, the lake water at the bottom flows along the surface of the guide plate 33 towards the mounting seat 1, so that the lake water at the bottom flows to the upper level, thus circulating the lake water at the bottom and the upper level. The lake water flowing to the upper level is oxygenated by the actuation mechanism 2, which effectively increases the oxygen content and oxygenation efficiency of the lake water. By increasing the oxygen content of the lake water, it is ensured that the fish in the water will not lack oxygen. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the pond water from deteriorating and threatening the survival environment of the fish.

[0027] A compression spring 34 and a limiting ring 35 are coaxially sleeved on the outer side of the transmission rod 31. The two ends of the compression spring 34 are fixedly mounted on the top of the transmission rod 31 and the limiting ring 35, respectively. When the compression spring 34 is in a compressed state and then relaxes, it pushes the limiting ring 35 to move closer to the connecting rod. The connecting rod is used to block the movement of the limiting ring 35. When the limiting ring 35 contacts the side wall of the connecting rod, one end of the transmission rod 31 and the rotating rod 32 respectively passes through the limiting ring 35. At this time, the limiting ring 35 restricts the position of the transmission rod 31 and the rotating rod 32, ensuring that the axes of the transmission rod 31 and the rotating rod 32 are on the same straight line. When the limiting ring 35 moves away from the connecting rod, and one end of the rotating rod 32 does not pass through the limiting ring 35, the rotating rod 32 can rotate around the position hinged to the transmission rod 31, that is, the rotating rod 32 can rotate around the axis of the connecting rod. When moving the mounting base 1, the operator pushes the limiting ring 35 closer to the mounting base 1. At this time, the compression spring 34 is in a compressed state. Then, the operator pushes the rotating rod 32 to rotate around the position hinged to the transmission rod 31 and closer to the mounting base 1, thereby retracting the rotating rod 32, reducing the volume of the oxygenation equipment, and making it easier for the operator to move the oxygenation equipment later. When the oxygenation equipment is in use, the rotating rod 32 is unfolded and coaxial with the transmission rod 31. At this time, when the compression spring 34 is in a compressed state, it pushes the limiting ring 35 closer to the connecting rod. At this time, the limiting ring 35 is located outside the transmission rod 31 and the rotating rod 32. The limiting ring 35 restricts the rotating rod 32 inside the transmission rod 31, preventing the rotating rod 32 from shaking too much when the transmission rod 31 drives the rotating rod 32 to rotate, and increasing the stability of the rotating rod 32 during rotation.

[0028] To enable the rotation of the shaft 21 and the transmission rod 31, a drive mechanism is provided inside the mounting base 1. This drive mechanism powers the actuating mechanism 2 and the guiding mechanism 3. The drive mechanism includes a worm gear 24 rotatably connected to the bottom of the mounting base 1. The worm gear 24 is located between the shaft 21 and the transmission rod 31, with opposite thread directions at both ends. A worm wheel 23 is coaxially fixed on the shaft 21 near the worm gear 24, meshing with the worm gear 24. When the worm gear 24 rotates, it drives the shaft 21 to rotate via the worm wheel 23. A transmission bevel gear 241 is coaxially fixed on the worm gear 24. A driven gear is coaxially fixed at one end of the transmission rod 31 inside the mounting base 1. A bevel gear 311, driven bevel gear 311 and transmission bevel gear 241 mesh together. When the worm 24 rotates, it drives the transmission rod 31 to rotate through the transmission bevel gear 241 and driven bevel gear 311. A motor 25 is fixedly installed inside the mounting base 1. The output shaft of the motor 25 is coaxially connected to one end of the worm 24 through a coupling. The rotating output shaft of the motor 25 drives the worm 24 to rotate. During the rotation of the worm 24, it drives the rotating shaft 21 and the lever plate 22 to rotate through the worm wheel 23. At the same time, the rotating worm 24 drives the driven bevel gear 311 to rotate through the transmission bevel gear 241. During the rotation of the driven bevel gear 311, it drives the transmission rod 31 to rotate.

[0029] In summary, the workflow of this solution is as follows: Workers use an air pump to fill the floating box 11 with gas through an air inflator and seal the air inflator. Then, workers move the mounting base 1 to the desired placement area in the lake. Next, workers unfold the rotating rod 32, which is coaxial with the transmission rod 31. When the compression spring 34, which is in a compressed state, relaxes, it pushes the limiting ring 35 to move closer to the connecting rod, thus restricting the rotating rod 32. Then, workers place the mounting base 1 into the lake. Under the buoyancy of the floating box 11, the mounting base 1 floats in the lake. The output shaft of the rotating motor 25 drives the worm gear 24 to rotate. During rotation, the worm gear 23 drives the rotating shaft 21 and the deflector 22 to rotate in opposite directions. The rotating deflector 22 pushes the lake water towards both sides of the mounting base 1, thereby raising the lake water to contact with the air. Oxygen from the air enters the water to oxygenate it. At the same time, the rotating worm gear 24 drives the transmission rod 31 and the rotating rod 32 to rotate through the transmission bevel gear 241 and the driven bevel gear 311. The rotating rod 32 drives the guide plate 33 to rotate, causing the lake water at the bottom to flow along the guide plate 33 to the mounting base 1, so that the lake water at the bottom and the top layers circulate. Then, under the action of the deflector mechanism 2, the lake water is oxygenated.
