Description

Technical Field

[0001] This utility model relates to the field of river aeration technology, specifically to a river aerator impeller structure. Background Technology

[0002] River aerators are environmental treatment devices specifically designed to improve the water quality of flowing water bodies such as rivers and canals. They powerfully agitate the water mechanically (e.g., using high-speed rotating impellers or jet devices), efficiently dissolving air (oxygen) into the water to increase dissolved oxygen concentration. Simultaneously, they promote mixing and circulation between the upper and lower water layers, effectively suppressing black and odorous water, accelerating pollutant degradation, and restoring the water body's self-purification capacity. It is one of the key technological equipment for urban river ecological restoration and water environment management.

[0003] Oxygen in the air cannot automatically dissolve in large quantities in static or slow-moving water. Impellers, by violently agitating the water (such as inverted umbrella-shaped spray curtains, propeller-shaped bubble cutting, and jet-shaped water-air mixing), greatly increase the water-air contact area and contact time, breaking down the air film resistance on the water surface and forcing oxygen to dissolve rapidly in the water. However, conventional impeller structures with exposed rotating blades or brush-like structures are prone to entanglement with floating debris such as aquatic plants, plastic bags, ropes, and fishing nets. Entanglement increases resistance, reduces rotational speed and oxygenation efficiency, and severe entanglement may lead to motor overload, bearing damage, or transmission component failure. Therefore, we propose an impeller structure for river aerators. Utility Model Content

[0004] The purpose of this invention is to provide a river aerator impeller structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A river aerator impeller structure includes: a vertical motor, a vertical reducer fixedly connected to the bottom of the vertical motor, characterized in that: a motor stabilizing plate is fixedly connected to the top of the vertical reducer, the motor stabilizing plate is fixedly connected to the back of the vertical motor, a coupling is fixedly connected to the bottom of the vertical reducer, the bottom of the coupling has multiple mounting slots, an impeller assembly is provided at the bottom of the vertical motor, and an anti-winding component is fixedly connected to the surface of the impeller assembly.

[0007] Preferably, the impeller assembly includes a connecting upper shaft, a first mounting groove, a connecting base, a rotating base block, an inverted impeller column, an impeller ring, a limiting slide rail, a connecting slider, and a cutting blade. The connecting upper shaft is located at the bottom of the vertical motor, and the first mounting groove is located at the top of the connecting upper shaft. The shape of the first mounting groove matches that of the vertical motor.

[0008] Preferably, the connecting base is fixedly connected to the bottom of the connecting upper shaft, the rotating base is fixedly connected to the bottom of the connecting base, the plurality of inverted impeller columns are radially fixedly connected to the surface of the rotating base, and the impeller ring is fixedly connected to one end of the plurality of inverted impeller columns.

[0009] Preferably, the plurality of limiting slide rails are fixedly connected to the inner wall of the inverted impeller column, the plurality of connecting sliders are slidably connected to the surface of the limiting slide rails, and the plurality of cutting blades are fixedly connected to one end of the connecting slider.

[0010] Preferably, the anti-winding assembly includes a protective cover, a second mounting groove, and a smooth fixing ball. The protective cover is fixedly connected to the surface of the impeller ring, and the second mounting groove is formed on the inner wall of the protective cover. The shape of the second mounting groove matches that of the impeller ring.

[0011] Preferably, a plurality of the smooth fixed balls are fixedly connected to the surface of the protective cover.

[0012] Preferably, a warning light is fixedly connected to one side of the top of the coupling.

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

[0014] 1. The warning light can illuminate the surrounding area to warn people and prevent them from approaching the device and being injured by the internal structure of the impeller assembly. The impeller assembly can greatly increase the water-air contact area and contact time by rotating and stirring the water, destroying the air film resistance on the water surface and forcing oxygen to dissolve quickly in the water. At the same time, it can cut tangled water plants and other debris with its own structure. It also works in conjunction with the anti-tangling component to prevent debris from getting tangled.

[0015] 2. The impeller assembly structure prevents water plants and other debris from tangling. It is mounted on the bottom of the vertical motor via the connecting shaft and the first mounting slot, which drives the entire impeller assembly to rotate. The connecting base and rotating base block provide a fixed base for one end of the inverted impeller column and impeller ring, which are arranged radially. While rotating, water is lifted from below and thrown into the air. The thrown water forms a water jump (water curtain, water droplets), which makes full and extensive contact with the air, achieving rapid oxygen dissolution. The two types of limit slide rails fixed on the inner wall and the connecting slider that slides on the surface will continue to move under the action of centrifugal force generated by the rotation. At this time, the cutting blade will also move on it to cut the nearby tangled debris. The cutting blade adopts a design with blades on both sides, top and bottom, so as to cut from all directions. The vertical motor adopts a reciprocating rotation design. This reciprocating rotation uses centrifugal force to help the cutting blade to reciprocate and cut, further improving the cutting effect of the device and the service life of the impeller assembly.

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A river aerator impeller structure includes: a vertical motor 1, a vertical reducer 2 fixedly connected to the bottom of the vertical motor 1, characterized in that: a motor stabilizing plate 3 is fixedly connected to the top of the vertical reducer 2, the motor stabilizing plate 3 is fixedly connected to the back of the vertical motor 1, a coupling 4 is fixedly connected to the bottom of the vertical reducer 2, a plurality of mounting slots 5 are provided at the bottom of the coupling 4, an impeller assembly 7 is provided at the bottom of the vertical motor 1, an anti-winding component 8 is fixedly connected to the surface of the impeller assembly 7, and a warning light 6 is fixedly connected to one side of the top of the coupling 4.

[0027] In this embodiment, the vertical motor 1, together with the vertical reducer 2 and the coupling 4, connects to the impeller assembly 7, thereby providing a rotational foundation for the impeller assembly 7. The motor stabilizing plate 3 provides a stable foundation for the vertical motor 1 during operation. The mounting groove 5 can use its own structure to help the device float more stably on the water surface. The warning light 6 can use its own light to warn the surroundings and prevent people from getting too close. During the rotation of the impeller assembly 7, its internal structure, together with the anti-entanglement component 8, cuts and cleans up the surrounding debris, further improving the service life of the device.

[0028] The impeller assembly 7 includes a connecting upper shaft 701, a first mounting groove 702, a connecting base 703, a rotating base block 704, an inverted impeller column 705, an impeller ring 706, a limiting slide rail 707, a connecting slider 708, and a cutting blade 709. The connecting upper shaft 701 is located at the bottom of the vertical motor 1, and the first mounting groove 702 is opened at the top of the connecting upper shaft 701. The shape of the first mounting groove 702 matches that of the vertical motor 1.

[0029] In this embodiment, the impeller assembly 7 is mounted on the bottom rotating shaft of the vertical motor 1 by connecting the upper shaft 701 and the first mounting groove 702, thereby driving the impeller assembly 7 to rotate, thus providing a basis for the rotation of the impeller assembly 7 as a whole.

[0030] The connecting base 703 is fixedly connected to the bottom of the connecting upper shaft 701, the rotating base 704 is fixedly connected to the bottom of the connecting base 703, and multiple inverted impeller columns 705 are radially fixedly connected to the surface of the rotating base 704. The impeller ring 706 is fixedly connected to one end of the multiple inverted impeller columns 705.

[0031] In this embodiment, the connecting base 703 and the rotating base block 704 provide a fixed base for one end of the inverted impeller column 705 and the impeller ring 706, and are radially arranged. While being driven to rotate by the vertical motor 1, water is lifted from below and thrown into the air. The thrown water forms a water jump (water curtain, water droplets), which makes large-area and full contact with the air, realizing the rapid dissolution of oxygen and completing the basic function of the impeller structure.

[0032] Multiple limiting slide rails 707 are fixedly connected to the inner wall of the inverted impeller column 705, multiple connecting sliders 708 are slidably connected to the surface of the limiting slide rails 707, and multiple cutting blades 709 are fixedly connected to one end of the connecting sliders 708.

[0033] In this embodiment, the two limiting slide rails 707 fixed on the inner wall of the inverted impeller column 705 and the connecting slider 708 sliding on the surface will continue to move under the action of centrifugal force generated by rotation. The vertical motor 1 adopts a reciprocating rotation design, which uses centrifugal force to help the cutting blade 709 to perform reciprocating cutting. The cutting blade 709 adopts a design with blades on both sides, top and bottom, so as to cut from all directions, further improving the cutting effect of the device and the service life of the impeller assembly 7.

[0034] The anti-winding assembly 8 includes a protective cover 801, a second mounting groove 802, and a smooth fixing ball 803. The protective cover 801 is fixedly connected to the surface of the impeller ring 706. The second mounting groove 802 is formed in the inner wall of the protective cover 801, and the shape of the second mounting groove 802 matches the impeller ring 706.

[0035] In this embodiment, the anti-winding component 8 uses a protective cover 801 to cover the surface of the impeller ring 706, and uses the shape of the second mounting groove 802 to install and cover the surface of the impeller ring 706 in an arc shape. The arc shape and smooth material of the surface are used to prevent the wrapped material from further winding, thereby further improving the safety and functionality of the device.

[0036] Multiple smooth fixed balls 803 are fixedly connected to the surface of the protective cover 801.

[0037] In this embodiment, the smooth fixed ball 803 can improve the smoothness and complexity of the surface of the protective cover 801, thereby further utilizing multiple arc-shaped surfaces to prevent debris from tangling and improve the anti-tangling effect of the device.

[0038] Working principle: This device can be connected by a vertical motor 1 and a vertical reducer 2, and the vertical motor 1 is connected to the impeller assembly 7 through a coupling 4. This drives the impeller assembly 7 to rotate at a uniform speed and effectively. The reduction effect of the vertical reducer 2 is well known to those skilled in the art and will not be described in detail here. The motor stabilizing plate 3 can stabilize the vertical motor 1 from one side during operation, thereby increasing the overall stability of the device. The warning light 6 can use its own structure to emit light to warn people in the surrounding area and prevent them from approaching the device and being injured by contact with the internal structure of the impeller assembly 7. The impeller assembly 7 can greatly increase the water-air contact area and contact time by rotating and stirring the water, destroying the air film resistance on the water surface and forcing oxygen to dissolve in the water quickly. At the same time, it can use its own structure to cut entangled water plants and other debris, and combine with the anti-entanglement component 8 to prevent debris from getting entangled, thereby further improving the service life and rotation efficiency of the device.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
