[0002] The water surface cleaning robot is mainly used to collect and clean up debris on the water surface, keeping the water clean. The water surface cleaning robot can be controlled by a remote control or by a built-in computer program.

[0003] Chinese patent application CN202410402676.7 discloses an anti-tipping solar-powered water surface garbage cleaning robot, comprising a main body, a cleaning assembly, and a drive unit. Existing water surface garbage cleaning robots have relatively fixed buoyancy. As the amount of garbage collected changes, the robot's draft also changes, affecting the garbage collection efficiency. Furthermore, uneven distribution of garbage within the cleaning container can lead to different drafts on both sides, potentially causing the robot to tip over. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a surface garbage cleaner that can adjust buoyancy, change the draft of the surface garbage cleaner, and effectively prevent the surface garbage cleaner from tipping over.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model provides a water surface garbage cleaner, including a main body, a cleaning component and two floating components. The cleaning component is located inside the main body, and the two floating components are located on both sides of the main body. The floating component includes a floating and sinking cylinder and an adjusting piston. The floating and sinking cylinder is provided with a floating and sinking cavity with one end open. The adjusting piston is slidably disposed in the floating and sinking cylinder and divides the floating and sinking cavity into a variable-volume airtight cavity and an auxiliary cavity.

[0007] As an optional solution, the floating assembly also includes an adjusting motor and a ball screw mechanism that are connected by a transmission, wherein the adjusting motor drives the adjusting piston to move back and forth through the ball screw mechanism.

[0008] As an optional solution, the front end of the main body is provided with two gathering baffles, which gradually open from back to front, and the floating component is located behind the gathering baffles.

[0009] As an optional solution, the front end of the gathering baffle is rotatably provided with several guide wheels, and the rotation axis of the guide wheels extends vertically.

[0010] As an optional solution, the cleaning component includes fixed comb teeth and transfer comb teeth. The fixed comb teeth are fixed in the cleaning cavity of the main body, and the transfer comb teeth are rotatably disposed in the cleaning cavity. The transfer comb teeth and the fixed comb teeth are misaligned.

[0011] As an alternative, the transfer comb teeth include a plurality of spaced-apart first monomers, the monomers being cross-shaped.

[0012] As an option, the fixed comb teeth include a plurality of spaced second units, each second unit comprising a first part and a second part arranged at an angle, the first part being able to be inserted into water, and the rear end of the second part extending into the cleaning container.

[0013] As an optional solution, the cleaning assembly also includes a spiral feeder, which is rotatably disposed in front of the transfer comb teeth in the left-right direction.

[0014] As an optional embodiment, the cleaning component further includes a cleaning container, and a rotating pick-and-place door is provided at the rear of the main body, with the cleaning container located inside the main body.

[0015] As an optional solution, the surface debris cleaner also includes two propulsion components, each comprising a pusher, a housing, and a propeller. The housing has a frustum portion with several strip-shaped holes arranged circumferentially thereon, and the propeller is located inside the housing.

[0016] The beneficial effects of this utility model are:

[0017] The water surface debris cleaner provided by this utility model has two floating components on both sides of the main body, which can effectively prevent the water surface debris cleaner from tipping over. Furthermore, the airtight cavity volume of the floating components can be adjusted, thereby changing the buoyancy and allowing for adjustment of the water surface debris cleaner's draft. This ensures that the water surface debris cleaner can effectively clean up debris and maintain strong stability. In addition, even if the uneven distribution of debris on the water surface causes different weights on both sides of the water surface debris cleaner, the corresponding floating components can still be adjusted to ensure that the water surface debris cleaner always remains level and is not easily tipped over.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] Please refer to Figures 1-3 As shown, an embodiment of this utility model provides a water surface garbage cleaner 10, which can float on the water surface and collect and clean up the garbage on the water surface. Then, the user can collect the garbage and dispose of it in a centralized manner to keep the water surface clean.

[0034] It should be noted that the "front" and "back" mentioned in this embodiment are defined in terms of the direction of travel of the water surface garbage cleaner 10. In other embodiments, the relevant directions can be defined as needed, and the left and right directions are perpendicular to the front and back directions.

[0035] The surface debris cleaner 10 can be remotely controlled by a user via a remote control or can operate autonomously via a pre-programmed computer. If remotely controlled, the remote control's operating principle can refer to existing technology; for example, it can transmit signals via infrared. When the user presses a button, the remote control's internal circuitry generates a specific signal, which is then emitted via infrared. This signal is received by the surface debris cleaner 10, and its internal receiver decodes the signal to perform the necessary operations, such as controlling a motor to turn on a light. The control method of the surface debris cleaner 10 can be similar to that of drones or unmanned surface vessels, which is common knowledge and will not be elaborated upon here.

[0036] The surface debris cleaner 10 mainly consists of a main body 11, a floating component 13, a cleaning component 12, and a propulsion component 14. The floating component 13, cleaning component 12, and propulsion component 14 are all mounted on the main body 11. The floating component 13 allows the surface debris cleaner 10 to float on the water surface, the cleaning component 12 collects surface debris, and the propulsion component 14 propels the surface debris cleaner 10 forward. The following is a detailed description of each component of the surface debris cleaner 10.

[0037] The main body 11 primarily serves to connect and support the floating component 13, the cleaning component 12, and the propulsion component 14. The shape and structure of the main body 11 are not limited and can be a frame structure, a box structure, etc. In this embodiment, the main body 11 adopts a box structure, which has a top and several side walls. The transverse cross-section of the main body 11 is roughly rectangular. The rear end of the main body 11 may or may not be closed.

[0038] The interior of the main body 11 is hollow, forming a cleaning chamber. The size of the cleaning chamber is not limited and can be large or small, depending on the needs. The bottom side of the cleaning chamber is partially or completely open so that the cleaning component 12 can clean up the debris below the water surface. Of course, in some embodiments, depending on the structure of the cleaning component 12 and the method of collecting debris, the bottom side of the cleaning chamber may not be open.

[0039] The front opening of the cleaning chamber has no limit on its size or shape and can be set as needed so that when the main body 11 moves forward, the garbage can enter the cleaning chamber through the opening.

[0040] A camera can be installed at the top or front of the main body 11. The camera is used to observe the environment in front, so that the user can adjust the forward direction of the water surface debris cleaner 10 in a timely manner. Of course, a camera can also be omitted, and the user can observe the water surface conditions instead. Correspondingly, a panel can be installed on the remote control to display the image transmitted by the camera. Please refer to existing technology for the image transmission method.

[0041] In this embodiment, two gathering baffles 110 can be provided at the front end of the main body 11. The gathering baffles 110 can be plate-like structures, mesh structures, etc. In the direction from back to front, the two gathering baffles 110 gradually open outward, that is, the distance between the two gathering baffles 110 gradually increases. With this arrangement, the front ends of the two gathering baffles 110 can cover a larger area of ​​water surface, and the garbage can reach the front opening of the cleaning chamber along the gathering baffles 110, which can gather the garbage located in front of the main body 11 for easy collection. Of course, in other embodiments, it is also possible not to provide gathering baffles 110.

[0042] In addition, several guide wheels 111 can be provided at the front end of the gathering baffle 110. The number of guide wheels 111 is not limited, such as one, two, or three. In this embodiment, each gathering baffle 110 has two guide wheels 111 at its front end. The two guide wheels 111 are spaced apart in the vertical direction and are located at the frontmost part of the gathering baffle 110. The guide wheels 111 are rotatably mounted on the gathering baffle 110 and can rotate around their own axis of rotation, which extends vertically. When the surface garbage cleaner 10 comes into contact with stones or other objects on the shore or in the water, the guide wheels 111 can roll along the shore or stones, thereby changing the forward direction of the surface garbage cleaner 10.

[0043] The cleaning component 12 is located inside the main body 11. The structure of the cleaning component 12 is not limited and can refer to the prior art. For example, the cleaning component 12 includes a conveyor belt and a cleaning container 123. In the direction from back to front, the conveyor belt is gradually inclined downward. The front end of the conveyor belt is lower than the rear end. The front end of the conveyor belt can extend into the water. The circumference of the conveyor belt can also be provided with protrusions or multiple baffles. The rear end of the conveyor belt is higher than the water surface and is located above the cleaning container 123. The conveyor belt can transport the garbage on the water surface into the cleaning container 123.

[0044] In this embodiment, the cleaning component 12 may also employ, but is not limited to, the following methods: Please refer to... Figure 4 , Figure 5 As shown, the cleaning assembly 12 includes a cleaning container 123, a fixed comb tooth 120, a transfer comb tooth 121, and a spiral feeder 122.

[0045] The cleaning container 123 can be located inside or outside the main body 11. It is mainly used to hold the garbage after cleaning. When the amount of garbage on the surface of the water in the cleaning container 123 reaches a certain amount, the user can remove the cleaning container 123 and empty the garbage. The shape and structure of the cleaning container 123 are not limited. Its upper part or all of it is open so that garbage can fall into its interior. The cross-section of the cleaning container 123 can be circular, rectangular, irregular, etc.

[0046] To facilitate the retrieval and placement of the cleaning container 123 and prevent it from detaching abnormally from the main body 11, a rotating retrieval door 112 is provided at the rear of the main body 11 in this embodiment. The retrieval door 112 can refer to the structure of existing doors, and there can be one or two retrieval doors 112. The retrieval door 112 can be opened or closed. When the retrieval door 112 is open, the user can place the cleaning container 123 into the main body 11 or remove the cleaning container 123 from the main body 11 for cleaning. When the retrieval door 112 is closed, it seals the opening at the rear end of the main body 11, preventing the cleaning container 123 from detaching from the rear end of the main body 11 and ensuring the stability of the cleaning container 123.

[0047] The fixed comb teeth 120 and the transfer comb teeth 121 are used to transfer garbage on the water surface to the cleaning container 123. The fixed comb teeth 120 are fixed in the cleaning chamber, and the transfer comb teeth 121 are rotatably disposed in the cleaning chamber. The transfer comb teeth 121 and the fixed comb teeth 120 are staggered.

[0048] Specifically, the transfer comb 121 includes several first units. The number of first units is unlimited and can be set as needed, such as ten, fifteen, twenty, etc. Multiple first units are distributed at intervals along the left and right directions, and the interval distance can be large or small.

[0049] Each unit includes a rotating part and transfer arms. The number of transfer arms is not limited and can be two, three, four, etc. Multiple transfer arms can extend radially outward from the center. For example, if there are four transfer arms, they can surround the rotating part in a cross shape. In other embodiments, each unit can be in a straight line shape, etc.

[0050] A rotating shaft is installed inside the main body 11, and a rotating part is sleeved on the rotating shaft. The rotating shaft is rotatably installed inside the main body 11. One end of the rotating shaft is driven to rotate by a cleaning motor 124, etc., so that the rotating shaft and the transfer comb teeth 121 can rotate around their own center line. The cleaning motor 124 and the rotating shaft can be driven by a belt and pulley, or by a sprocket and chain mechanism. A remote control or the like can remotely control the cleaning motor 124 to start or stop, thereby realizing the rotation and stationary position of the transfer comb teeth 121. Of course, the cleaning motor 124 can also be manually turned on when the water surface garbage cleaner 10 is placed in water.

[0051] The fixed comb teeth 120 include several second units, while the number of first units is unlimited, such as ten, fifteen, or twenty. These second units are spaced apart along a left-right direction, with varying intervals. Generally, the second units of the fixed comb teeth 120 and the first units of the transfer comb teeth 121 are alternately distributed, meaning that one second unit is placed between two adjacent first units. Of course, it is also possible to have multiple second units between two adjacent first units, or multiple first units between two adjacent second units.

[0052] The second unit comprises a first part and a second part, which are arranged at an angle. The angle is not limited; for example, they can be perpendicular and form an L-shape, or roughly J-shaped. The first part can be inserted downwards into the water to ensure that garbage on the water surface can be blocked by the first part. The rear end of the second part extends into the cleaning container 123.

[0053] When the transfer comb 121 rotates, it can rotate and transport the surface debris in front of the first part to the second part or directly into the cleaning container 123. As more and more debris accumulates, the debris at the rear of the second part can push the debris in front into the cleaning container 123. In some embodiments, in order to allow the debris on the second part to smoothly enter the cleaning container 123, the second part can also be configured to gradually extend downward from front to back, so that the surface debris can slide into the cleaning container 123.

[0054] The cleaning assembly 12 may also include a spiral feeder 122, which extends in the left-right direction and is rotatably mounted on the main body 11. The spiral feeder 122 is located in front of the transfer comb teeth 121. One end of the spiral feeder 122 is driven to rotate by a feeding motor 125, etc., so that the spiral feeder 122 can rotate around its own center line. The feeding motor 125 and the rotating shaft of the spiral feeder 122 can be driven by a belt and pulley, or by a sprocket and chain mechanism. A remote control or the like can remotely control the feeding motor 125 to start or stop, thereby realizing the forward rotation, flipping, and stationary movement of the spiral feeder 122.

[0055] When the screw feeder 122 rotates, it can push the surface debris to the left or right, thereby evenly transferring the debris to different positions in the cleaning container 123 and ensuring the balance of the surface debris cleaner 10. For example, if the surface debris enters the cleaning chamber from the left and there is more debris on the left side of the cleaning container 123, the left side of the surface debris cleaner 10 will be heavier, causing the left side of the surface debris cleaner 10 to have a deeper water intake. In this case, to make the surface debris more evenly distributed in different positions in the cleaning container 123, the screw feeder 122 can be used to transport the subsequent surface debris to the right, so that the subsequent surface debris enters the cleaning container 123 from the right side. This structure is particularly suitable for situations where the surface debris cleaner 10 is large. When the surface debris cleaner 10 is small, the screw feeder 122 can be omitted.

[0056] Two floating components 13 are located on both sides of the main body 11. This arrangement ensures that the center of gravity of the surface debris cleaner 10 is in the middle, effectively preventing the surface debris cleaner 10 from tipping over.

[0057] Please combine Figure 6 , Figure 7 As shown, each floating assembly 13 includes a floating and sinking cylinder 130 and an adjusting piston 131. The floating and sinking cylinder 130 is provided with a floating and sinking cavity with one end open. The adjusting piston 131 is slidably disposed in the floating and sinking cylinder 130 and divides the floating and sinking cavity into an airtight cavity with variable volume and an auxiliary cavity.

[0058] The shape of the floating and sinking cylinder 130 is not limited. For example, it can be a cylindrical structure, a prismatic structure, or an irregular shape. In this embodiment, the floating and sinking cylinder 130 is roughly cylindrical.

[0059] When the volume of the airtight chamber inside the floating cylinder 130 changes, the amount of gas inside changes. A larger gas volume results in greater buoyancy, and vice versa. By adjusting the piston 131 to change the volume of the airtight chamber, the buoyancy of the surface debris cleaner 10 can be adjusted, thereby changing its draft. When there is little debris in the cleaning container 123, the draft of the surface debris cleaner 10 is shallow. In this case, the volume of the airtight chamber can be reduced to increase the draft of the surface debris cleaner 10, allowing the cleaning component 12 to collect and clean the surface debris smoothly. When there is a lot of debris in the cleaning container 123, the draft of the surface debris cleaner 10 is deep. In this case, the volume of the airtight chamber can be increased to decrease the draft of the surface debris cleaner 10, preventing the cleaning container 123 from sinking. The auxiliary chamber can be filled with water or not.

[0060] The float / sinking cylinder 130 and / or adjusting piston 131 are equipped with a first one-way valve and a second one-way valve. The first one-way valve only allows gas to enter the airtight chamber from the outside, while the second one-way valve only allows gas to exit from the airtight chamber to the outside. This configuration ensures that the amount of gas inside the airtight chamber changes when its volume changes. Of course, the first and second one-way valves can also be combined into a bidirectional airflow valve, but it must be ensured that gas cannot pass through the bidirectional airflow valve when the adjusting piston 131 remains stationary.

[0061] The movement control method of the adjusting piston 131 within the float-sinking cylinder 130 is not limited. For example, in this embodiment, the following scheme can be adopted, but is not limited to: the floating assembly 13 also includes an adjusting motor 132 and a ball screw mechanism 133 with transmission cooperation. The adjusting motor 132 drives the adjusting piston 131 to move back and forth through the ball screw mechanism 133. Specifically, the ball screw mechanism 133 includes a screw and a nut. The screw is rotatably supported within the float-sinking cylinder 130 and extends in the front-back direction. The screw is in transmission cooperation with the output shaft of the adjusting motor 132. The adjusting piston 131 is slidably disposed within the float-sinking cylinder 130 in the front-back direction. The nut is disposed on the adjusting piston 131 and cooperates with the screw. One end of the screw is driven by a motor, etc. When the adjusting motor 132 drives the screw to rotate around its own center line, the adjusting piston 131 can move in the front-back direction. Of course, it should be noted that it is necessary to ensure the sealing between the screw and the nut, and between the adjusting piston and the float-sinking cylinder 130, which can be achieved by sealing rings, etc.

[0062] In some other embodiments, the adjusting piston 131 can also slide within the float-sink cylinder 130 in other ways. For example, the floating assembly 13 further includes a telescopic cylinder, with its two ends connected to the adjusting piston 131 and the float-sink cylinder 130, respectively. The telescopic cylinder can extend or retract, thereby driving the adjusting movement within the float-sink cylinder 130. Both the motor and the telescopic cylinder can be started or stopped via a remote control or an internal computer program.

[0063] The floating component 13 is located behind the gathering baffle 110. This arrangement can effectively ensure that surface debris does not reach the floating component 13, and the floating component 13 is also less likely to bump into the baffle.

[0064] The surface debris cleaner 10 is propelled forward by the propulsion components 14. The number of propulsion components 14 is not limited, such as one, two, three, etc. In this embodiment, the surface debris cleaner 10 includes two propulsion components 14, which are located on both sides of the rear end of the main body 11.

[0065] Please combine Figure 8 , Figure 9 As shown, the propulsion assembly 14 includes a pusher 140, a housing 141, and a propeller 142.

[0066] The pusher 140 can be a drive motor, or it can have a housing on the outside of the drive motor. The pusher 140 is fixed to the main body 11. The propeller 142 needs to be submerged in water. The propeller 142 is connected to the output shaft of the motor. The two can be directly connected or indirectly connected through a gear reducer, etc. When the motor rotates, it can drive the propeller 142 to rotate, thereby applying thrust to the surface garbage cleaner 10. The motor can be controlled to turn on or off via a remote control.

[0067] The casing 141 has a frustum-shaped portion 143, with several strip-shaped holes arranged around its circumference. The propeller 142 is located inside the casing 141. Water can flow through the strip-shaped holes to reach the propeller 142, but surface debris cannot pass through, preventing it from becoming entangled on the propeller 142 and effectively protecting it. Alternatively, a cylindrical portion can be provided at the rear end of the frustum-shaped portion 143, enclosing the propeller 142.

[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
