Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a water surface cleaner. Background Technology

[0002] With the increasing demand for aquatic environment management, the application of water surface cleaning equipment is becoming more and more widespread.

[0003] Current water cleaners mostly adopt an open structure, with core components such as the drive unit in direct contact with the water. This makes them susceptible to corrosion from salt spray, biofouling, and abrasion from sediment, resulting in short equipment lifespan and high maintenance costs. Furthermore, the open structure prevents the cleaning components from effectively controlling water flow, leading to significant water disturbance during the cleaning process and reduced cleaning efficiency.

[0005] A water surface cleaner includes: a housing, a drive assembly, a cleaning assembly, and a propulsion assembly;

[0006] A first and a second accommodating cavity are formed within the housing;

[0007] The cleaning component is at least partially located within the first receiving cavity;

[0008] The drive assembly is sealed within the second receiving cavity; the propulsion assembly is disposed on the outer side of the housing corresponding to the second receiving cavity;

[0009] The drive assembly drives and connects the propulsion assembly and the cleaning assembly respectively; the propulsion assembly is used to move the water surface cleaner under the control of the drive assembly.

[0010] The housing has an inlet and an outlet that connect to the first receiving cavity. The water to be cleaned enters the first receiving cavity through the inlet, is cleaned by the cleaning component, and is discharged from the outlet.

[0014] In an optional embodiment, the propeller includes at least two propulsion blades, which are arranged around the shaft of the propeller and are distributed at different angles.

[0015] In an optional embodiment, the propulsion component is propelled from the second receiving cavity to the first receiving cavity, so as to guide the water to be cleaned into the first receiving cavity.

[0016] In an optional embodiment, a protective shell assembly is provided on the outer side of the propulsion assembly.

[0017] In an optional embodiment, the protective shell assembly is at least partially provided with a mesh structure, the aperture of which is less than 1 / 5 of the length of the propulsion assembly, to prevent debris from entering the propulsion assembly.

[0036] Example 1

[0037] As per the instruction manual Figure 1-5 As shown, the water surface cleaner provided in this embodiment includes:

[0038] 1. Housing; 2. Drive assembly; 3. Cleaning assembly; 4. Propulsion assembly;

[0039] The housing 1 forms a first receiving cavity 10 and a second receiving cavity 11 connected to each other; the cleaning component 3 is at least partially located in the first receiving cavity 10, and the driving component 2 is sealed in the second receiving cavity 11; the propulsion component 4 is disposed on the housing 1 on the outside corresponding to the second receiving cavity 11.

[0040] The drive component 2 drives and connects the propulsion component 4 and the cleaning component 3 respectively; the propulsion component 4 is used to move the water surface cleaner under the control of the drive component 2.

[0041] The housing 1 has an inlet 12 and an outlet 13 that connect to the first receiving cavity 10. The water to be cleaned enters the first receiving cavity 10 through the inlet 12, is cleaned by the cleaning component 3, and is discharged from the outlet 13.

[0042] In some specific embodiments, the housing 1 is made of high-strength, corrosion-resistant engineering plastics or stainless steel to ensure long-term stable operation in complex aquatic environments. (See attached document.) Figure 4 As shown, the device is internally divided into a first receiving cavity 10 and a second receiving cavity 11, which are connected to each other. The first receiving cavity 10 serves as the core area for cleaning operations and can house cleaning devices (such as cleaning brushes, filters, etc.). The second receiving cavity 11 is used to install and protect the drive assembly 2, preventing it from getting damp or damaged. The cavity layout of the first receiving cavity 10 and the second receiving cavity 11 optimizes the overall space utilization of the water surface cleaner, ensures the independent operation of the cleaning assembly 3 and the drive assembly 2, avoids mutual interference, and improves the overall reliability and service life of the device.

[0043] Optionally, the drive assembly 2 may include a high-efficiency motor, a reducer, and an intelligent control system, all sealed within the second receiving cavity 11 to ensure waterproofing and dustproofing. The motor is connected to the propulsion assembly 4 and the cleaning assembly 3 via the reducer to achieve power transmission. The intelligent control system is responsible for receiving remote commands or preset programs and precisely controlling the motor's speed and direction, thereby adjusting the cleaner's movement path and cleaning intensity. This allows the cleaner to flexibly adjust its working mode according to actual needs, improving cleaning efficiency and intelligence.

[0044] Optionally, the cleaning component 3 may include a filter screen, a rotating brush, a filtration unit, and a suction pump. The filter screen is located at the front end of the water inlet 12 of the surface cleaner or in the water flow channel. Its mesh structure intercepts large floating particles (such as fallen leaves, plastic bottles, and aquatic plants) on the water surface and in the water body. These large floating particles are retained on the filter screen surface or in a matching collection basket / box, achieving initial separation of pollutants and preventing large particles from clogging the subsequent rotating brush or suction pump, ensuring the normal operation of the surface cleaner. The rotating brush is driven by a motor to rotate at high speed. The resulting water vortex causes small particles (such as silt and plankton) in the water to detach from their attachment surfaces and suspend in the water, forming a mixture. This provides deep cleaning for sticky pollutants that are difficult to remove using traditional physical methods. The filtration unit (such as a filter bag or filter cartridge) is located downstream of the rotating brush and upstream of the suction pump, performing fine separation of impurities in the mixture. The suction pump generates negative pressure through impeller rotation, simultaneously drawing in the water filtered by the filter screen and the mixture filtered by the filter unit from the inlet 12. This mixture is then transported through pipes to the outlet 13 and discharged into an external collection container or a recycling system. The clean water can be returned to the water body. The filter screen → rotating brush → suction pump are arranged linearly, ensuring that water flows sequentially through each component, forming a continuous cleaning path of "interception → stripping → fine filtration → suction," effectively removing pollutants from the water body.

[0045] Optionally, the propulsion assembly 4 can take the form of a propeller or a water jet propulsion device. The number of propulsion assemblies 4 can be one, two, or more. The propulsion assembly 4 is connected to the drive assembly 2 and generates thrust under the drive of a motor. Taking a propeller as an example, its rotation pushes water backward, and the reaction force of the water propels the cleaner to move freely on the water surface. Specifically, the propulsion assembly 4 propels the surface cleaner along the direction from the second receiving cavity 11 to the first receiving cavity 10. This flexible propulsion system allows the cleaner to cover a wider water area, achieving efficient cleaning operations.

[0046] Optionally, refer to the appendix. Figure 1 and attached Figure 2As shown, the housing 1 has an inlet 12 and an outlet 13 that connect to the first receiving cavity 10. The water to be cleaned enters the first receiving cavity 10 through the inlet 12, and after being filtered, scrubbed and vacuumed by the cleaning component 3, it is discharged from the outlet 13, forming a continuous water circulation cleaning process, which effectively improves cleaning efficiency and reduces manual intervention.

[0047] In an optional embodiment, the water surface cleaner includes two propulsion components 4, both of which are disposed on the outer side of the housing 1 corresponding to the second receiving cavity 11; the two propulsion components 4 are respectively driven and connected to the drive component 2.

[0048] Optionally, the water surface cleaner may include two propulsion components 4, each of which can be connected to the drive component 2 via an independent drive shaft or gear system to achieve separate driving. This allows the two propulsion components 4 to independently control their speed and direction, providing the cleaner with more flexible and precise control capabilities.

[0049] Optionally, propulsion assembly 4 can employ a speed-adjustable propeller. The propeller blades are designed with hydrodynamic optimization to generate stable thrust at different speeds while reducing energy consumption and noise. Furthermore, the propeller can be made of corrosion-resistant materials to adapt to various water conditions.

[0050] The dual propulsion assembly 4 enables the surface cleaner to move more flexibly and quickly on the water surface, greatly improving its maneuverability and response speed. Facing different water environments and cleaning needs, the dual propulsion assembly 4 allows the surface cleaner to flexibly adjust its operating mode. For example, in narrow or obstacle-filled waters, the speed of one propulsion assembly can be reduced or its direction changed, allowing the cleaner to navigate with a smaller turning radius; when rapid movement or crossing open water is required, the speed of both propulsion assemblies can be increased simultaneously for rapid navigation.

[0051] In an optional embodiment, the two propulsion components 4 are symmetrically arranged on the outer side of the housing 1 corresponding to the second receiving cavity 11, with the center line of the housing 1 as the central axis.

[0052] Optionally, the two propulsion components 4 are symmetrically arranged about the centerline of the housing 1, which ensures that the thrust of the cleaner is evenly distributed during navigation, which helps to maintain navigation stability.

[0053] Optionally, each propulsion assembly 4 may employ a high-performance electric propeller with specially designed blades to optimize hydrodynamic performance and reduce energy consumption and noise. The propeller is connected to the housing 1 via an adjustable bracket, facilitating adjustments to the propulsion angle and height to adapt to different aquatic environments and operational requirements.

[0054] Optionally, refer to the appendix. Figure 1 As shown, each of the propulsion components 4 is provided with a protective shell component 5 on its outer side. The protective shell component 5 can be made of high-strength, corrosion-resistant alloy material or engineering plastic to ensure its stability and durability during long-term underwater operation. The protective shell component 5 effectively prevents external objects (such as floating objects, branches, stones, etc.) from directly impacting the propulsion component 4, thereby protecting it from damage.

[0055] Optionally, at least a portion of the protective shell assembly 5 employs a mesh structure 50 design. This mesh structure not only ensures smooth water flow and reduces water resistance, but also effectively prevents larger debris from entering the propulsion assembly 4 area. Specifically, the aperture of the mesh structure 50 is less than 1 / 5 of the length of the propulsion assembly 4, ensuring sufficient water permeability while effectively reducing the risk of debris entering.

[0056] Optionally, refer to the appendix. Figure 5 As shown, the propulsion assembly 4 includes a propeller 40. The shaft of the propeller 40 can be driven to the output shaft of the drive assembly 2 through a coupling or gear transmission system, ensuring the high efficiency and stability of power transmission.

[0057] Optionally, the propeller 40 includes at least two propulsion blades 41, which are arranged around the shaft of the propeller 40 and are distributed at different angles. Specifically, the installation angle (i.e., pitch angle) of the propulsion blades 41 can be adjusted according to actual cleaning needs. For example, some blades can be designed with a larger pitch angle to provide stronger thrust, while others can be designed with a smaller pitch angle to optimize the efficiency of water flow.

[0058] Optionally, the propulsion blade 41 can be designed with hydrodynamic optimization to reduce water resistance and improve propulsion efficiency. The propulsion blade 41 can be made of high-strength, corrosion-resistant alloy or composite material to ensure stability and durability during long-term underwater operations.

[0059] Optionally, the propulsion direction of the propulsion component 4 is set to a thrust from the second receiving cavity 11 to the first receiving cavity 10, which not only propels the cleaner forward, but also helps guide the water to be cleaned into the first receiving cavity 10, further improving the working efficiency of the water surface cleaner.

[0060] Furthermore, in order to ensure propulsion efficiency and water flow guidance effect, the blade shape, angle and rotation speed of the propulsion component 4 can be optimized by fluid dynamics, so that the propulsion component 4 can generate thrust while minimizing energy loss and water flow resistance.

[0061] In an optional embodiment, the water surface cleaner further includes a power supply assembly 6; the power supply assembly 6 is sealed within the second receiving cavity 11 and is electrically connected to the drive assembly 2.

[0062] Optionally, the power supply assembly 6 can adopt an integrated injection-molded waterproof housing. The housing material is made of high-strength, corrosion-resistant engineering plastics (such as modified polycarbonate), and double-layer silicone sealing rings and ultrasonic welding process are used at the seams to ensure waterproof performance.

[0063] Meanwhile, the power supply assembly 6 can be fixed inside the second receiving cavity 11 by a high-damping spring shock absorber, and together with the honeycomb aluminum alloy bracket, absorbs impact energy to ensure stable operation under acceleration vibration. The power supply assembly 6 significantly improves the water surface cleaner's endurance, operational stability, and environmental adaptability.

[0064] In an optional embodiment, the drive assembly 2, and / or the cleaning assembly 3, and / or the propulsion assembly 4, and / or the outer surface of the housing 1, and / or the channel wall of the inlet 12, and / or the outlet 13, and / or all airflow contact surfaces of the first receiving cavity 10, and / or the second receiving cavity 11 are covered with a waterproof and corrosion-resistant coating.

[0065] In some embodiments, the waterproof and corrosion-resistant coating can be made using advanced nanotechnology or polymer materials (e.g., nano-coatings, nano-modified polyurethane coatings, polymer waterproof films, etc.), exhibiting excellent waterproof, moisture-proof, and corrosion-resistant properties. The waterproof and corrosion-resistant coating can adhere tightly to the outer surface of each component of the water surface cleaner, effectively preventing water and moisture from penetrating into the interior of the coating.

[0066] The beneficial effects of this application are as follows: By sealing the drive components and other components within the second receiving cavity, completely isolating them from the water, this physical isolation and sealing design reduces the risks of salt spray corrosion, biofouling, and silt abrasion, extending the overall service life of the equipment and reducing maintenance costs. Furthermore, the cleaning component is located within the enclosed first receiving cavity. Water enters through the inlet, is treated by the cleaning component, and then exits through the outlet, forming a directional flow path. This constrains the water flow direction, preventing disorderly disturbance of the water during cleaning and allowing contaminants to efficiently contact the cleaning component, thereby improving its cleaning efficiency. The drive component simultaneously drives both the propulsion and cleaning components, enabling them to work collaboratively and further improving operational efficiency.

[0067] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
