Description

Technical Field

[0001] This invention belongs to the field of cleaning technology and relates to a water surface cleaning device and method. Background Technology

[0002] Currently, water surface management remains a major challenge in aquatic environmental governance. Eutrophication of lakes is a common phenomenon in our lives, and scenic lakes are polluted by algae, household waste, and kitchen waste. Traditional manual inspection and dredging methods are too labor-intensive and complex, and the cleaning boats are too large to be suitable for cleaning some small and medium-sized scenic lakes. To improve water surface cleaning efficiency and save manpower and resources, an innovative, lightweight, and automated water surface cleaning robot has emerged.

[0003] According to patents [CN 212024916U] on a water conservancy algae removal device and [CN 218058605 U] on an ecological floating island device, both utilize mechanical devices such as guide plates and rotating paddles to complete the intake and discharge process. Currently, commercially available filter devices draw the electrolyte solution into the electrolyte filter, and then, under natural force, the electrolyte enters from the inlet water and passes through the filter element. The stainless steel filter element has dense pores; these uniform small pores constitute the pore size of the electrolyte filter. The disadvantage is that the small pore size results in an inflexible filtration mechanism, leading to easy clogging and difficulty in cleaning during the filtration process. Secondly, while surface garbage collection and purification boats have been released on the market, they are too large, require high costs, occupy a significant amount of water area affecting aesthetics, and are difficult to maneuver in medium-sized bodies of water, making them unsuitable for cleaning landscape lakes. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing water surface cleaning equipment being prone to clogging and difficult to clean during filtration, as well as the problems of existing equipment being too large, occupying a large water area, and being difficult to operate in medium-sized water bodies. The invention provides a water surface cleaning device and method.

[0005] To achieve the above objectives, the present invention employs the following technical solution: A water surface cleaning device includes a housing, inside which a first cavity and a second cavity are provided in communication with each other. A plurality of valves are provided between the first cavity and the second cavity. A filter assembly is provided at each valve. A water inlet is provided on the first cavity, and a water outlet is provided on the housing. The water outlet is connected to the second cavity through one or more of the valves. The second cavity is equipped with a drive disk unit, which divides the second cavity into an upper cavity and a lower cavity that are spaced apart. A canard-like wing and a drive unit are provided on the side wall of the outer shell, and the canard-like wing is rotatably connected to the outer shell.

[0006] A further improvement of the present invention is that: A partition is provided between the first cavity and the second cavity, and an installation groove is provided on the partition for installing valves and filter components. The valve is opened, closed, or rotated by a motor.

[0007] The filtering component is a filter screen.

[0008] The drive disk unit includes a connecting shaft with a drive motor mounted on it. The drive end of the drive motor is connected to a rotating disk. The rotating disk is sequentially connected to a second transmission rod and a first transmission rod. The first transmission rod is connected to a pressure plate. The pressure plate divides the second cavity into an upper cavity and a lower cavity that are spaced apart.

[0009] The rotating disks are symmetrically distributed along both ends of the connecting shaft.

[0010] The upper part of the outer casing is provided with a top cover, and the water inlet is opened on the top cover.

[0011] A motor cavity is formed on the side wall of the outer shell, and a motor is placed inside the motor cavity. The drive end of the motor is connected to a canard-like wing.

[0012] The drive unit includes a drive housing, inside which a drive motor is installed. The drive motor is connected to a rotating shaft, and the rotating shaft is connected to a propeller.

[0013] The canard-like wing is symmetrically arranged in two parts.

[0014] A method for cleaning a water surface includes the following steps: Water flows from the inlet into the first chamber and the second chamber in sequence. At this time, the valve connected to the outlet is closed, while the other valves are open. When the second chamber is filled with water, the drive disc unit moves upward. At this time, the valve in the upper chamber that is connected to the water outlet is opened, and the other valves in the upper chamber are closed. The water in the upper chamber is discharged through the water outlet. When the drive disc unit moves downward, it opens the valve in the lower cavity that connects to the outlet and closes the other valves in the lower cavity, allowing the water in the lower cavity to be discharged through the outlet. As the liquid flows, the filter assembly filters impurities sequentially into the first chamber and the second chamber.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a water surface cleaning device, including a first chamber and a second chamber. Water to be filtered enters the first chamber and the second chamber sequentially and then flows out through an outlet. Valves are provided between the first chamber, the second chamber, and the outlet, and filter components are installed at the valves. The water flow can be filtered twice, and larger impurities are mainly retained in the first chamber, which not only facilitates later cleaning but also prevents blockage at the outlet of the second chamber. The drive disc unit divides the second chamber into upper and lower parts. By repeatedly moving the drive disc unit up and down, the water pressure in the upper and lower chambers is changed, generating a certain driving force for the water flow, avoiding internal blockage, and improving the internal filtration efficiency.

[0016] This invention discloses a water surface cleaning method. When filtering and cleaning water, the water flows into the first chamber through the upper inlet. At this time, larger debris in the water also enters the first chamber. When the water flows into the second chamber through the valve, the first layer of filtration by the filter assembly will block the larger debris in the first chamber. At this time, the pore size of the filter screen at the valve corresponding to the outlet in the second chamber can be adjusted. When the water in the second chamber is discharged through the outlet, the filter screen with smaller pore size will perform a second filtration on the water flow, blocking the smaller debris in the second chamber. After two blocking processes, the larger debris is filtered into the first chamber, and the smaller debris is filtered into the second chamber, thus improving the cleaning efficiency of the water flow.

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings: See Figure 1 This invention discloses a water surface cleaning device, comprising a main outer shell (inlet, outlet, and one-way plate), a drive disc, a rotating rod, a drive motor, and an inner cylinder. The outer cylinder is heptagonal in front and side views, with four inlets connected to the upper part and an outlet at the rear. The outlet at the rear of the outer shell connects to the inner cylinder to form a drainage channel. The motor is located under the top cover and on both sides of the outer shell, with its output end sequentially matched with the drive disc and rotating rod, responsible for power operation. A pressure cover is matched above the inner cylinder. The solid-liquid separation module in the inner cylinder is located at the front end of the inner cylinder, below the inlet, and faces the impact of the incoming water flow laterally. Specifically, it includes the following structure: Example 1 See Figures 1 to 2This invention discloses a water surface cleaning device, including a housing 4. The housing 4 contains a first cavity and a second cavity that are interconnected. A plurality of valves 9 are disposed between the first cavity and the second cavity. A filter assembly is disposed at each valve 9. An inlet is provided on the first cavity, and an outlet 11 is provided on the housing 4. The outlet 11 is connected to the second cavity through one or more of the valves 9. A drive disc unit is disposed inside the second cavity, dividing it into an upper cavity and a lower cavity that are spaced apart. A canard-like wing 7 and a drive unit 12 are disposed on the side wall of the housing 4, and the canard-like wing 7 is rotatably connected to the housing 4.

[0026] Furthermore, in this embodiment, the upper end of the outer casing 4 is provided with a top cover 8, and the lower end is connected to the chassis 3, forming an overall heptagonal shape. Both the top cover 8 and the chassis 3 are assembled with the outer casing 4 using bolts, fasteners 1, and washers 2. Specifically, chassis mounting holes 3-1 are formed on the end face of the chassis 3. (See [reference]). Figure 3 The top cover 8 has a top cover mounting hole 8-1. A mounting plate 6 is provided on the inner side wall of the outer shell 4. The mounting plate 6 has a shell mounting hole. The mounting plate 6 is located near the upper and lower ends of the outer shell 4 and is respectively matched with the top cover mounting hole 8-1 and the chassis mounting hole 3-1 to achieve assembly.

[0027] See Figure 3 Furthermore, in this embodiment, the water inlet is opened on the top cover 8. Specifically, four water inlets 8-2 are opened on the top cover 8, and the four water inlets 8-2 are distributed at intervals. The top cover 8 also has a circuit cavity 8-3, and a sliding cover 10 is provided on the circuit cavity 8-3. The circuit cavity 8-3 is mainly used to place circuit devices.

[0028] Furthermore, in this embodiment, the water to be filtered enters the first chamber and the second chamber sequentially and then flows out through the outlet. Valves are opened between the first chamber, the second chamber, and the outlet, and filter components are installed at the valves. The water flow can be filtered twice, and the larger impurities filtered out will mainly remain in the first chamber, which not only facilitates later cleaning but also prevents blockage at the outlet of the second chamber. The drive disc unit divides the second chamber into upper and lower parts. By repeatedly moving the drive disc unit up and down, the water pressure in the upper and lower chambers is changed, which generates a certain driving force for the water flow, avoids internal blockage, and improves the internal filtration efficiency.

[0029] Example 2 This invention discloses a water surface cleaning device, including a housing 4. The housing 4 contains a first cavity and a second cavity that are interconnected. A plurality of valves 9 are disposed between the first and second cavities, and filter components are installed at each valve 9. An inlet is provided on the first cavity, and an outlet 11 is provided on the housing 4. The outlet 11 is connected to the second cavity through one or more valves 9. A drive disc unit is disposed inside the second cavity, dividing it into an upper cavity and a lower cavity spaced apart. A canard-like wing 7 and a drive unit 12 are disposed on the side wall of the housing 4. The canard-like wing 7 is rotatably connected to the housing 4. A partition is provided between the first and second cavities, and an installation groove 3-2 is provided on the partition. Valves 9 and filter components are installed in the installation groove 3-2. The valves 9 are opened, closed, or rotated by a motor.

[0030] Furthermore, in this embodiment, the outer shell 4 has a heptagonal structure.

[0031] Furthermore, in this embodiment, several valves 9 are distributed around the partition, and there are two vertically distributed circumferentially. Among them, two valves 9 corresponding vertically are connected to the outlet 11, and the other valves 9 are connected to the first cavity and the second cavity.

[0032] See Figure 4 Furthermore, in this embodiment, a cavity 3-3 is provided on one side of the second cavity, and a water outlet 11 is opened on the cavity 3-3. The second cavity and the cavity 3-3 are connected through a valve 9.

[0033] See Figure 4 Furthermore, in this embodiment, the specific installation structure of valve 9 is as follows: A partition is provided between the first cavity and the second cavity. An installation groove 3-2 is formed on the partition, and a valve 9 is installed on the installation groove 3-2. The valve 9 consists of two mating one-way plates, which are rotatably connected to the side wall of the installation groove 3-2. (See [reference]). Figures 5 to 6 The one-way valve has an opening angle of 90° and an outer wall that is arc-shaped to better accommodate water flow. The one-way valve is used in conjunction with the MG995 servo motor to open or close. In this embodiment, the installation position of the MG995 servo motor is not specifically limited, as long as it can achieve electrical control of the one-way valve.

[0034] Furthermore, in this embodiment, the filter component is a filter screen, and the size of the filter pores on the filter screen can be adjusted according to the actual situation.

[0035] Furthermore, in this embodiment, the specific structure of the drive disk unit is as follows: See Figures 7 to 9The second cavity is the inner cylinder 5. The drive disc unit includes a connecting shaft 5-2, on which a drive motor is mounted. There are two drive motors, which are distributed along the axial direction of the connecting shaft 5-2. The drive end of each drive motor is connected to a rotating disc 5-1. The two rotating discs 5-1 are located at both ends of the connecting shaft 5-2. The rotating disc 5-1 is rotatably connected to a second transmission rod, which is rotatably connected to a first transmission rod 5-3. The first transmission rod 5-3 is rotatably connected to a pressure plate 5-4. Specifically, a connecting block is mounted on the pressure plate 5-4, and a rotating shaft is mounted on the side wall of the connecting block. The rotating shaft is rotatably connected to the transmission rod 5-3.

[0036] In this embodiment, the first transmission rod 5-3, the second transmission rod, and the pressure plate 5-4 adopt a single-axis transmission hinge method to make the bottom negative pressure plate move up and down reciprocally, thereby generating negative pressure opening and closing power.

[0037] See Figure 10 Furthermore, in this embodiment, the drive unit mounting area 3-4 is mainly the location for mounting the drive unit 12. Two drive units 12 are spaced apart. The specific structure of the drive unit 12 is as follows: The drive unit 12 includes a drive housing 12-1, inside which a drive motor is installed. The drive motor is connected to a rotating shaft 12-2, and the rotating shaft 12-2 is connected to a propeller 12-3. The drive unit 12 provides the power for the device to move forward.

[0038] Furthermore, in this embodiment, two canard-like wings 7 are symmetrically arranged, specifically: On the side wall of outer casing 4, see Figure 4 The device has a corresponding motor cavity 3-5, in which a motor is placed. The motor has a rotating transmission rod 13 at its drive end, which is connected to a canard-like wing 7. The motor drives the canard-like wing 7 to rotate. The canard-like wing 7 controls the direction of movement of the body by steering and is used to balance the stable movement of the body in the water.

[0039] Example 3 See Figures 11 to 13 This embodiment also discloses a water surface cleaning method, including the following steps: Water flows into the first chamber and the second chamber sequentially from the inlet. At this time, the valve 9 connected to the outlet 11 is closed, while the other valves 9 are open. When the second chamber is filled with water, the drive disc unit moves upward. At this time, the valve 9 in the upper chamber that is connected to the outlet 11 is opened, and the other valves 9 in the upper chamber are closed. The water in the upper chamber is discharged through the outlet 11. When the drive disc unit moves downward, the valve 9 in the lower cavity that is connected to the outlet 11 is opened, and the other valves 9 in the lower cavity are closed, so that the water in the lower cavity is discharged through the outlet 11. As the liquid flows, the filter assembly filters impurities sequentially into the first chamber and the second chamber.

[0040] Specifically, in this embodiment, the upper cavity and the lower cavity each have a valve 9 connected to the water outlet 11. When the entire machine is submerged, the chambers will be filled with water. At this time, the valves 9 corresponding to the upper cavity and the lower cavity respectively will be closed, and all other valves will be opened. See [link to documentation]. Figure 11 ; The pressure plate 5-4 is driven upwards, reducing the space in the upper cavity. This opens valve 9, which connects to outlet 11 in the upper cavity, while all other valves remain closed. Water then flows out of the upper cavity through outlet 11. (See [reference]). Figure 12 ; The pressure plate 5-4 moves downward, reducing the space in the lower cavity. This opens valve 9, which connects to outlet 11 in the lower cavity, while all other valves 9 remain closed. Water then flows out of the lower cavity through outlet 11. (See [reference]). Figure 13 ; When the pressure plate 5-4 moves downward or upward, it increases the pressure in the corresponding cavity, driving the water flow to be discharged quickly, accelerating the driving force of the internal water flow, and improving the filtration efficiency of the water flow.

[0041] During filtration, water first enters the first chamber through the upper inlet 8-2. Larger impurities in the water also enter the first chamber. When the water flows into the second chamber through valve 9, the first layer of filtration by the filter screen will block the larger impurities in the first chamber. At this time, the aperture size of the filter screen at valve 9 corresponding to the outlet 11 in the second chamber can be adjusted. When the water in the second chamber is discharged through the outlet 11, the filter screen with smaller aperture will perform a second filtration on the water flow, blocking the smaller impurities in the second chamber. After two layers of filtration, the larger impurities are filtered into the first chamber, and the smaller impurities are filtered into the second chamber, improving the cleaning efficiency of the water flow.

[0042] Meanwhile, since the top cover 8 is removed, the first cavity and the second cavity are two separate chambers, which makes it easy to clean up debris.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
