Description

Technical Field

[0001] This utility model relates to the field of river oxygenation technology, specifically a floating adjustable-angle river aeration oxygenator. Background Technology

[0002] River aerators are oxygenation devices specifically designed for naturally flowing water bodies. They are typically installed in float or fixed positions and use high-efficiency aeration devices (such as vortex blowers, microporous aeration discs, or powerful impellers) to force air into the deep water of rivers, significantly increasing dissolved oxygen content, accelerating the decomposition of pollutants, inhibiting algal blooms, and activating microbial activity. This rapidly improves black and odorous water bodies, restores the river's self-purification capacity and ecological balance, and is one of the core pieces of equipment for urban water environment management. There are many types of river aerators.

[0003] In the management of extremely shallow, slow-flowing, and enclosed river channels, waterwheel-type aerators can be classified as a special type of river aeration and oxygenation equipment. They expand the gas-liquid exchange area by high-speed impact on the water surface, achieving oxygenation of the surface water. Simultaneously, they promote water mixing through horizontal flow, undertaking ecological restoration functions in specific scenarios. However, waterwheel-type river aerators are prone to being covered by aquatic plants or algae during use, leading to blockages with prolonged use and requiring frequent cleaning, which is quite troublesome. Therefore, we propose a floating, adjustable-angle river aerator. Utility Model Content

[0004] The purpose of this invention is to provide a floating, adjustable-angle river aeration and oxygenation machine 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 floating, adjustable-angle river aerator includes: a motor protective shell, the inner wall of which is equipped with a dual-shaft motor; characterized in that: connecting shafts are provided on both sides of the dual-shaft motor, multiple impeller assemblies are fixedly connected to the surface of the connecting shafts, multiple cleaning components are provided on the top of each impeller assembly, multiple connecting floats are provided at the bottom of the motor protective shell, float cylinders are fixedly connected to the bottom of each of the two connecting floats, a connecting frame is fixedly connected between the connecting floats, and a connecting bracket is fixedly connected to one side of each of the two connecting floats, the position of the connecting bracket matching the connecting shaft.

[0007] Preferably, the impeller assembly includes a connecting housing, a fixing hole, a rotating plate, an impeller plate, a connecting box, a limiting slide rail, a connecting slider, and a cleaning brush. The connecting housing is disposed on the surface of the connecting shaft, and the fixing hole is formed in the inner wall of the connecting housing. The shape and size of the fixing hole match the connecting shaft.

[0008] Preferably, a plurality of the rotating plates are fixedly connected to the surface of the connecting housing, the impeller plate is fixedly connected to one end of the rotating plates, and the surface of the impeller plate is provided with a plurality of evenly distributed holes.

[0009] Preferably, the connecting box is fixedly connected to one side of the impeller plate, the limiting slide rail is fixedly connected to the inner wall of the connecting box, the connecting slider is slidably connected to the surface of the limiting slide rail, the cleaning brush is fixedly connected to the surface of the connecting slider, and the size of the cleaning brush matches the position of the impeller plate.

[0010] Preferably, the plurality of cleaning components include a connecting block, a fixing nail, a connecting plate, and a cleaning insert plate, wherein the connecting block is fixedly connected to the top of the impeller plate, and the fixing nail is fixedly connected to the bottom of the connecting block.

[0011] Preferably, the connecting plate is fixedly connected to the surface of the connecting block, and a plurality of cleaning inserts are fixedly connected to the bottom of the connecting plate, the position of the cleaning inserts matching the movement trajectory of the cleaning brush.

[0012] Preferably, an adjustable propeller is provided at the bottom of one of the connecting floats.

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

[0014] 1. By connecting the rotating shaft, the rotation of the shaft drives the rotation of multiple connected impeller components. This rotation provides basic surface aeration. At the same time, the structure itself helps to self-clean aquatic impurities such as aquatic plants under the centrifugal force of rotation. It also works in conjunction with the cleaning components to prevent aquatic plants from adhering to the surface during the self-cleaning process and affecting its use.

[0015] 2. Water surface aeration is achieved through the structure of the impeller assembly. The impeller plates on the impeller assembly strike the water surface vertically or at an angle, lifting and breaking the water into fine droplets and waves, thereby increasing the water-air contact area. The droplets and waves greatly increase the contact surface area between the water and the air, while promoting oxygen dissolution. Oxygen in the air quickly dissolves into these droplets and waves through the gas-liquid interface, ultimately driving the water flow. While the impeller plates strike the water, they generate a horizontal thrust, propelling the surface water of the pond to flow in a directional direction, forming a water circulation. At the same time, under the action of centrifugal force, the connecting slider moves up and down inside the connecting box. The limiting slide rail limits and guides its movement trajectory, while simultaneously driving the cleaning brush to clean the impeller plate surface, further improving the cleanliness of the device.

[0016] 3. By adjusting the connecting float in the middle of the propeller structure, the internal motor can be started to rotate when needed, thereby adjusting the angle of the entire device to the required position. This angle adjustment facilitates aeration of the desired area, thus further improving the overall functionality of the device. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] Example

[0028] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0029] A floating, adjustable-angle river aerator includes: a motor protective shell 1, with a dual-shaft motor 2 installed on the inner wall of the motor protective shell 1. The dual-shaft motor 2 has connecting shafts 3 on both sides, multiple impeller assemblies 4 fixedly connected to the surface of the connecting shafts 3, multiple cleaning assemblies 5 on the top of each impeller assembly 4, multiple connecting floats 6 at the bottom of the motor protective shell 1, floats 10 fixedly connected to the bottom of each connecting float 6, a connecting frame 8 fixedly connected between the connecting floats 6, and a connecting bracket 9 fixedly connected to one side of each connecting float 6. The position of the connecting bracket 9 matches the connecting shaft 3, and an adjusting propeller 7 is installed at the bottom of one of the connecting floats 6.

[0030] In this embodiment, the motor protective shell 1 helps provide a waterproof and safe environment for the dual-shaft motor 2 inside the device, making it easier for the dual-shaft motor 2 to drive the rotation of the connecting shaft 3 more safely while being fixed. This rotation provides a rotational basis for the overall rotation of the impeller assembly 4. The impeller assembly 4 uses rotation to beat the water surface, effectively breaking up the temperature and dissolved oxygen stratification of the river water, allowing the upper and lower layers of water to exchange, pushing the low-oxygen water at the bottom to the surface to increase oxygen, and pushing the oxygen-rich water at the surface to the bottom. At the same time, the centrifugal force of rotation drives the internal structure to move to help self-clean the inside of the impeller assembly 4, and in combination with the cleaning component 5, it further improves the device's waterproofness and prevents the accumulation of aquatic impurities such as algae. The connecting float 6 and the float 10 are combined to provide a basis for the floating of the device. The adjustable propeller 7 can help adjust the floating angle of the device to facilitate aeration at the corresponding angle position. The connecting frame 8 can connect multiple connecting floats 6, and together with the connecting frame 9, it further strengthens the overall installation and fixation of the device.

[0031] The impeller assembly 4 includes a connecting housing 401, a fixing hole 402, a rotating plate 403, an impeller plate 404, a connecting box 405, a limiting slide rail 406, a connecting slider 407, and a cleaning brush 408. The connecting housing 401 is disposed on the surface of the connecting shaft 3, and the fixing hole 402 is opened in the inner wall of the connecting housing 401. The shape and size of the fixing hole 402 match the connecting shaft 3.

[0032] In this embodiment, the impeller assembly 4 is connected to the rotating shaft 3 through the connecting housing 401 and the fixing hole 402, so that it can rotate under the action of the dual-shaft motor 2. This structure provides the overall rotation basis for the impeller assembly 4.

[0033] Multiple rotating plates 403 are fixedly connected to the surface of the connecting housing 401, and an impeller plate 404 is fixedly connected to one end of the rotating plates 403. The surface of the impeller plate 404 is provided with multiple holes evenly distributed.

[0034] In this embodiment, rotation drives the rotating plate 403 to rotate, which in turn drives the impeller plate 404 to rotate. The impeller plate 404 strikes the water surface vertically or at an angle, lifting and breaking the water into small droplets and waves, thereby increasing the water-air contact area. The droplets and waves greatly increase the contact surface area between the water and the air, while promoting oxygen dissolution. Oxygen in the air quickly dissolves into these droplets and waves through the gas-liquid interface, which in turn propels the water flow. While the impeller plate 404 strikes the water, it generates a horizontal thrust, which propels the surface water of the pond to flow in a directional direction, forming a water circulation.

[0035] The connecting box 405 is fixedly connected to one side of the impeller plate 404, the limiting slide rail 406 is fixedly connected to the inner wall of the connecting box 405, the connecting slider 407 is slidably connected to the surface of the limiting slide rail 406, and the cleaning brush 408 is fixedly connected to the surface of the connecting slider 407. The size of the cleaning brush 408 matches the position of the impeller plate 404.

[0036] In this embodiment, the connecting box 405 utilizes its internal space and the limiting slide rail 406 to provide the connecting slider 407 with a space for movement and limiting guidance. The change in centrifugal force and inertia generated when the impeller plate 404 rotates will cause the connecting slider 407 to move up and down on the surface of the limiting slide rail 406, thereby driving the cleaning brush 408 to move up and down to prevent debris from accumulating on the surface of the impeller plate 404 and causing blockage of the internal holes, thus affecting the use and further improving the functionality and safety of the device.

[0037] Multiple cleaning components 5 include a connecting block 501, a fixing nail 502, a connecting plate 503, and a cleaning insert plate 504. The connecting block 501 is fixedly connected to the top of the impeller plate 404, and the fixing nail 502 is fixedly connected to the bottom of the connecting block 501.

[0038] In this embodiment, the cleaning component 5 is connected to the top of the impeller plate 404 via the connecting block 501. At the same time, the fixing nail 502 can help to reinforce the fixing of the connecting block 501 to the top of the impeller plate 404, thereby providing a stable foundation for the overall use of the cleaning component 5.

[0039] The connecting plate 503 is fixedly connected to the surface of the connecting block 501, and multiple cleaning inserts 504 are fixedly connected to the bottom of the connecting plate 503. The position of the cleaning inserts 504 matches the movement trajectory of the cleaning brush 408.

[0040] In this embodiment, the connecting plate 503 is fixed to the surface of the connecting block 501. When the impeller plate 404 rotates, it will drive the connecting block 501 to rotate, thereby driving the connecting plate 503 to rotate. At this time, the multiple cleaning inserts 504 at the bottom of the connecting plate 503 will continuously clean the inside of the cleaning brush 408 that hits the part. This cleaning activity prevents impurities from accumulating inside the cleaning brush 408, thereby further improving the functionality of the device.

[0041] Working principle: The device protects the internal dual-shaft motor 2 through the motor protective shell 1. The dual-shaft motor 2 drives the connecting shafts 3 on both sides to rotate, thus providing the rotational foundation for the entire device. The connecting shafts 3 drive the connected multiple impeller assemblies 4 to rotate by their own rotation, providing basic water surface aeration. At the same time, the structure itself helps to self-clean aquatic impurities such as aquatic plants under the centrifugal force of rotation. It also works in conjunction with the cleaning assembly 5 to prevent aquatic plants from adhering to the device during the self-cleaning process and affecting its use. The adjustable propeller 7 can help adjust the overall angle of the device. Meanwhile, the connecting frame 8 and the connecting bracket 9 work together to help connect and reinforce the entire device. The float 10 and the connecting float plate 6 work together to help the device float from the bottom, further improving the functionality of the device.

[0042] 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.
