Description

Technical Field

[0001] The utility model relates to a water surface cleaning machine capable of preventing grounding, and belongs to the field of water surface cleaning robots. Background Art

[0002] Existing water surface cleaning robots are prone to run aground when moving on a non-uniform surface or a surface with a certain slope (such as cement, tiles or sand).

[0003] Furthermore, a Chinese patent (Announcement No.: CN220374716U) discloses an anti-grounding water surface cleaning robot, including a main body and an anti-grounding device, wherein the anti-grounding device is rotatably arranged at the bottom of the main body. The water surface cleaning robot has a retractable anti-grounding structure, and the user can decide whether to turn on the anti-grounding function according to the needs of the actual use scenario. When the anti-grounding device is turned on, the anti-grounding device interferes with structures such as steps in the pool, thereby preventing the water surface cleaning robot from rushing to the shallow water area, thereby playing a role in preventing grounding.

[0004] The above scheme prevents the water surface cleaning robot from running into shallow water areas by setting up a rod-shaped anti-grounding device, thereby achieving the purpose of preventing grounding. However, when the rod-shaped anti-grounding device encounters hard obstacles in shallow water areas (such as cement, tiles, and mats), the impact force is relatively large, which may cause damage to the obstacles, the anti-grounding device, and the water surface cleaning robot, affecting the service life; at the same time, when the anti-grounding device with a rod-shaped structure encounters soft obstacles (such as beaches and mud) in shallow water areas, the rod-shaped structure is easily directly inserted into the soft obstacles, causing the water surface cleaning robot to be stuck. Therefore, the above-mentioned rod-shaped anti-grounding device has poor maneuverability and applicability, which is not conducive to the promotion and use of water surface cleaning robots.

[0005] The information disclosed in this background art is only for understanding the background of the concept of the present invention and therefore it may include information that does not constitute the prior art. Utility Model Content

[0006] In response to the above problem or one of the above problems, one purpose of the utility model is to provide a water surface cleaning machine that can prevent running aground, and a rotating part is installed on the machine body, and the rotating part is installed at the lower end or below the machine body in a rolling manner. When the water surface cleaning robot encounters a slope, the rotating part can roll on the slope, so that the machine body can move along the slope, thereby effectively preventing the water surface cleaning robot from running aground.

[0007] In response to the above problem or one of the above problems, the second purpose of the utility model is to provide a water surface cleaning machine that can prevent grounding. By setting a rotating part to reduce the resistance between the water surface cleaning robot and the ground, the water surface cleaning robot can move more easily on uneven or sloped surfaces (such as cement, tiles or beaches), reducing the risk of grounding, enhancing the maneuverability of the water surface cleaning robot in various ground environments, and improving its stability, thereby improving the working efficiency and applicability of the water surface cleaning robot, enabling it to smoothly perform cleaning tasks in a wider range of environments, which is conducive to the promotion and use of water surface cleaning robots.

[0008] In response to the above problem or one of the above problems, the third purpose of the utility model is to provide a water surface cleaning machine that can prevent grounding. By introducing a rotating part, it helps to reduce the contact area between the water surface cleaning robot and the slope, thereby reducing adhesion and improving the maneuverability of the water surface cleaning robot in changeable terrain. On a slope of a certain slope, the rotating part can provide additional traction to help the water surface cleaning robot climb the slope instead of running aground. By assembling the rotating part, it helps to maintain the balance of the water surface cleaning robot on the slope.

[0009] In order to achieve one of the above purposes, a technical solution of the utility model is:

[0010] A water surface cleaning machine capable of preventing grounding comprises a body for achieving water surface cleaning and a rotating part for preventing the water surface cleaning robot from being grounded;

[0011] The rotating member is assembled at the lower end or below of the body in a rolling manner, so that when the water surface cleaning robot encounters a slope, the rotating member can roll on the slope so that the body can move along the slope.

[0012] After continuous exploration and testing, the utility model assembles a rotating part on the body, and the rotating part is assembled at the lower end or below the body in a rolling manner. When the water surface cleaning robot encounters a slope, the rotating part can roll on the slope, so that the body can move along the slope, thereby effectively preventing the water surface cleaning robot from running aground.

[0013] Furthermore, the anti-grounding device of the utility model is a rotating part. When encountering hard obstacles (cement, tiles, mats) in shallow water areas, rolling friction is used to replace traditional sliding friction and scraping limit of the rod-shaped structure, thereby reducing the impact on obstacles, anti-grounding rotating parts and the robot body, reducing the risk of damage and extending the service life of the machine; at the same time, when the rotating part encounters soft obstacles (beach, mud) in shallow water areas, it is not easy to sink and can continue to move, thereby effectively avoiding the surface cleaning robot from getting stuck.

[0014] Therefore, the utility model reduces the resistance between the water surface cleaning robot and the ground by setting a rotating part, so that the water surface cleaning robot can move more easily on uneven or sloped surfaces (such as cement, tiles or beaches), reducing the risk of running aground, enhancing the maneuverability of the water surface cleaning robot in various ground environments, and also improving its stability, thereby improving the working efficiency and applicability of the water surface cleaning robot, enabling it to smoothly perform cleaning tasks in a wider range of environments, which is conducive to the promotion and use of the water surface cleaning robot.

[0015] Going further, when the water surface cleaning robot encounters a slope, the gravity component on the slope may cause the water surface cleaning robot to adhere to the surface, especially on soft surfaces such as beaches. The introduction of rotating parts helps to reduce the contact area between the water surface cleaning robot and the slope, thereby reducing the adhesion. Different slope surfaces may have different roughness and slopes, and the rotating parts can better adapt to these changes and improve the maneuverability of the water surface cleaning robot in changing terrain. On a slope with a certain slope, the rotating parts can provide additional traction to help the water surface cleaning robot climb the slope instead of running aground. The use of rotating parts helps to maintain the balance of the water surface cleaning robot on the slope, especially when the water surface cleaning robot needs to turn or move on an uneven slope.

[0016] Furthermore, the slope is the ground or pool wall in the shallow water area or a protrusion in the deep water area. It can be a slope paved with cement or tiles, or a beach area by the water or a shore paved with mud.

[0017] As the preferred technical measures:

[0018] The number of the rotating parts is multiple, which is one, two, three or four.

[0019] As the preferred technical measures:

[0020] The number of the rotating member is one, which is assembled in the front end area of ​​the lower end of the body;

[0021] Or / and, the number of the rotating parts is two, which are respectively assembled on the two side areas of the lower end of the body;

[0023] Or / and, the number of the rotating parts is four, and they are symmetrically distributed at the lower end of the machine body.

[0024] Preferably, in order to optimize the power distribution of the water surface cleaning robot and solve the problem of movement on slopes, four rotating parts are assembled, and the four rotating parts are symmetrically distributed at the lower end of the body, which helps to disperse the weight of the water surface cleaning robot and reduce the pressure per unit area, thereby improving stability and traction on soft or uneven surfaces; the water surface cleaning robot can more easily move in all directions, including lateral movement and rotation, so that it can be used in various complex terrains; and by evenly distributing the power of the water surface cleaning robot, the possibility of a single rotating part slipping due to excessive load is reduced.

[0025] As the preferred technical measures:

[0026] The rotating part is a ball wheel, a wheel, a cylindrical wheel or a spline gear.

[0027] As the preferred technical measures:

[0028] The ball wheel is made of nylon, polyurethane or synthetic rubber and is assembled on the machine body through a bracket.

[0029] The utility model fully considers the size, weight and environment of the water surface cleaning robot. The ball wheel is made of nylon, polyurethane or synthetic rubber, which is light and durable. These materials can not only support the weight of the water surface cleaning robot, but also provide good wear resistance and necessary buoyancy, thereby ensuring the smooth movement of the water surface cleaning robot on the water surface.

[0030] As the preferred technical measures:

[0031] The bracket is a U-shaped structure, a V-shaped structure, an arc-shaped structure or a triangular structure, and is connected to the ball wheel through a pin shaft and is rotatably connected to the chassis of the machine body through a bearing.

[0032] The ball wheel is installed by the bracket, so that the installation of the ball wheel is stable and reliable, which can effectively ensure the stability and durability during cleaning operations.

[0033] The bearing is a high-performance bearing having a low friction coefficient and high durability to minimize energy loss during rotation and extend service life.

[0034] Furthermore, the ball wheel is connected to the bracket via a pin shaft, which is convenient for replacement and installation, so that it can be quickly repaired or replaced when worn or damaged, thereby reducing the downtime of the water surface cleaning robot.

[0035] Or / and, the bracket includes an arc-shaped cavity for assembling the ball wheel and a horizontally extending rearward-inclined portion for assembling the bearing, and the vertical projections of the rearward-inclined portion and the arc-shaped cavity do not overlap or partially overlap, so that the installation position of the ball wheel is misaligned with the installation position of the bearing, forming a non-interference assembly structure, which is convenient for quick loading and unloading and maintenance of the ball wheel, bracket, bearing and connecting plate.

[0036] As the preferred technical measures:

[0037] The bracket, pin shaft, bearing and ball wheel are provided with a waterproof structure;

[0038] Providing a waterproof structure can effectively prevent moisture from intruding and causing performance degradation or damage to the bracket, pin shaft, bearing and ball wheel.

[0039] Or / and, the fixed end of the bearing is connected to the body through a connecting plate, and the rotating end is fixedly connected to the ball wheel; the connecting plate is fixedly connected to the chassis of the body, so that the bracket and the ball wheel can rotate 360 ​​degrees relative to the body, thereby achieving 360-degree anti-grounding.

[0040] As the preferred technical measures:

[0041] The rotating member protrudes from the lower surface of the machine body through a telescopic structure, forming a supporting structure with an adjustable protruding height of the rotating member.

[0042] As the preferred technical measures:

[0043] One end of the telescopic structure is a telescopic rod, and the other end is a U-shaped structure;

[0044] The telescopic rod is rotatably connected to the lower end of the machine body; the U-shaped structure is rotatably connected to the rotating member via a pin shaft.

[0045] The telescopic structure is provided to adjust the extension height of the rotating part, so that it can be better adapted to various complex terrains.

[0046] As the preferred technical measures:

[0047] The rotating member is a ball wheel, which is assembled at the four corners of the machine body to form a four-corner rolling anti-grounding structure;

[0048] When the water surface cleaning robot encounters a slope, the gravity component on the slope may cause the water surface cleaning robot to adhere to the surface, especially in soft places such as beaches. The design of the ball wheel helps to reduce the contact area between the water surface cleaning robot and the slope, thereby reducing the adhesion. Since different slope surfaces may have different roughness and slopes, the ball wheel can better adapt to these changes, thereby improving the maneuverability of the water surface cleaning robot in complex terrain. On a slope with a certain slope, the ball wheel can provide additional traction to help the water surface cleaning robot climb smoothly and avoid running aground. The use of the ball wheel helps to maintain the balance of the water surface cleaning robot on the slope, especially when it needs to turn or drive on an uneven slope.

[0049] The ball wheel of the utility model is a wheel with high wear resistance and good waterproof performance. The wear resistance ensures that the ball wheel can maintain its original shape and size after long-term contact with different water quality and underwater terrain, thereby ensuring the movement efficiency and service life of the water surface cleaning robot.

[0050] Alternatively, the rotating member is a wheel, which is assembled on the machine body through a universal joint to form a universal wheel structure.

[0051] Or / and, an anti-collision component is installed at the upper end of the front end of the body, and the anti-collision component includes three rotating wheels, and the three rotating wheels are arranged in a finished product shape, so as to further reduce the impact force of the collision between the body and the obstacle and extend the service life of the body.

[0052] The lower end of the rear end of the body is equipped with a propeller and a rotary motor for driving the body to move;

[0053] A filter plate with a plurality of through holes is installed in the middle area of ​​the lower end of the machine body.

[0054] Compared with the existing technical solutions, the utility model has the following beneficial effects:

[0055] After continuous exploration and testing, the utility model assembles a rotating part on the body, and the rotating part is assembled at the lower end or below the body in a rolling manner. When the water surface cleaning robot encounters a slope, the rotating part can roll on the slope, so that the body can move along the slope, thereby effectively preventing the water surface cleaning robot from running aground.

[0056] Furthermore, the anti-grounding device of the utility model is a rotating part. When encountering hard obstacles (cement, tiles, mats) in shallow water areas, rolling friction is used to replace traditional sliding friction and scraping limit of the rod-shaped structure, so the impact force is very small, which can effectively avoid damage to the obstacles, the anti-grounding device and the water surface cleaning robot, and extend the service life of the machine; at the same time, when the rotating part encounters soft obstacles (beach, mud) in shallow water areas, it is not easy to get stuck and can continue to move, thereby effectively avoiding the water surface cleaning robot from getting stuck.

[0057] Furthermore, the utility model reduces the resistance between the water surface cleaning robot and the ground by providing a rotating part, so that the water surface cleaning robot can move more easily on uneven or sloped surfaces (such as cement, tiles or beaches), reducing the risk of running aground, enhancing the maneuverability of the water surface cleaning robot in various ground environments, and also improving its stability, thereby improving the working efficiency and applicability of the water surface cleaning robot, enabling it to smoothly perform cleaning tasks in a wider range of environments, thereby facilitating the promotion and use of the water surface cleaning robot.

[0068] It should be noted that when two elements are "fixedly connected" or "rollingly connected", the two elements may be directly connected or there may be an intermediate element. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "side", "end", "upper", "lower", "vertical" and similar expressions used herein are for illustrative purposes only.

[0069] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0070] like Figure 1-Figure 4 As shown, the first specific embodiment of the water surface cleaning robot capable of preventing grounding of the utility model is:

[0071] A surface cleaning machine capable of preventing grounding comprises a body 1 for cleaning the surface of the water, and a rotating part for preventing the surface cleaning robot from being grounded; the rotating part is assembled at the lower end or below the body 1 in a rolling manner, so that when the surface cleaning robot encounters a slope, the rotating part can roll on the slope, so that the body 1 can move along the slope.

[0072] When a surface cleaning robot encounters a slope, the gravity component on the slope may cause the surface cleaning robot to adhere to the surface, especially on soft surfaces such as beaches. The introduction of rotating parts helps to reduce the contact area between the surface cleaning robot and the slope, thereby reducing adhesion. Different slope surfaces may have different roughness and slopes, and rotating parts can better adapt to these changes and improve the maneuverability of the surface cleaning robot in changing terrain. On a slope with a certain slope, the rotating parts can provide additional traction to help the surface cleaning robot climb the slope instead of running aground. The use of rotating parts helps to maintain the balance of the surface cleaning robot on the slope, especially when the surface cleaning robot needs to turn or move on an uneven slope.

[0073] In this embodiment, there are four rotating parts, which are symmetrically distributed at the lower end of the machine body 1.

[0074] The rotating member is a ball wheel 2. The ball wheel 2 is made of synthetic rubber and is assembled on the body 1 through a bracket 3.

[0075] In this embodiment, the bracket 3 is connected to the ball wheel 2 via a pin shaft 4 and is rotatably connected to the chassis 8 of the body 1 via a bearing 10 .

[0076] The bracket 3 includes an arc-shaped cavity 12 for assembling the ball wheel 2 and a horizontally extending rearwardly inclined portion 11 for assembling the bearing 10. The vertical projections of the rearwardly inclined portion 11 and the arc-shaped cavity 12 do not overlap or partially overlap, so that the installation position of the ball wheel 2 and the installation position of the bearing 10 are misaligned, forming a non-interference assembly structure, which is convenient for quick loading and unloading and maintenance of the ball wheel 2, the bracket 3, the bearing 10 and the connecting plate 9.

[0077] The bearing 10 is a high-performance bearing 10, which has a low friction coefficient and high durability to minimize energy loss during rotation and extend service life. The bracket 3, the pin 4, the bearing 10 and the ball wheel 2 are provided with a waterproof structure; the waterproof structure can effectively prevent moisture from invading and causing performance degradation or damage to the bracket 3, the pin 4, the bearing 10 and the ball wheel 2.

[0078] The fixed end of the bearing 10 is connected to the body 1 through a connecting plate 9, and the rotating end thereof is fixedly connected to the ball wheel 2; the connecting plate 9 is fixedly connected to the chassis 8 of the body 1, so that the bracket 3 and the ball wheel 2 can rotate 360 ​​degrees relative to the body 1.

[0079] The second specific embodiment of the water surface cleaning robot capable of preventing grounding of the utility model is as follows:

[0080] A water surface cleaning machine capable of preventing grounding comprises a body 1 for cleaning the water surface and a rotating part for preventing the water surface cleaning robot from being grounded; the rotating part protrudes from the lower surface of the body 1 through a telescopic structure, forming a supporting and erecting structure with adjustable protruding height of the rotating part. One end of the telescopic structure is a telescopic rod, and the other end is an arc structure; the telescopic rod is rotatably connected to the lower end of the body 1 through a bearing 10 and a connecting plate 9; the arc structure is rotatably connected to the rotating part through a pin 4.

[0081] The rotating part is a ball wheel 2 with high wear resistance and good waterproof performance, which is assembled at the four corners of the body 1 to form a four-corner rolling anti-grounding structure.

[0082] The third specific embodiment of the water surface cleaning robot capable of preventing grounding of the utility model:

[0083] A water surface cleaning machine capable of preventing grounding comprises a machine body 1 and four ball wheels 2.

[0084] The upper end of the front end of the body 1 is equipped with an anti-collision component, which includes three rotating wheels 5. The three rotating wheels 5 are arranged in a T-shaped pattern to further reduce the impact of collision between the body 1 and obstacles and extend the service life of the body 1. The lower end of the rear end of the body 1 is equipped with a propeller 6 and a rotary motor to drive the body 1 to move. The middle area of ​​the lower end of the body 1 is equipped with a filter plate 7 with a plurality of through holes.

[0085] The four ball wheels 2 are mounted on the chassis 8 of the body 1. The arrangement of the four ball wheels 2 helps to disperse the weight of the water surface cleaning robot and reduce the pressure per unit area, thereby improving the stability and traction on soft or uneven surfaces. In this way, the water surface cleaning robot is more easily moved in all directions, including lateral movement and rotation, so that it can be used in complex terrain. At the same time, this design also ensures that the power is more evenly distributed to each ball wheel 2, reducing the risk of the ball wheel slipping due to overload.

[0086] The ball wheels 2 are evenly distributed on the chassis 8 or other corresponding structures of the water surface cleaning robot through the bracket 3 to ensure balanced load and efficient power transmission. With the use of high-performance bearings 10, the energy loss during rotation is reduced and its service life is extended. The bearings 10 are designed with a waterproof function to prevent water intrusion from causing performance degradation or damage.

[0087] The ball wheel 2 is made of highly wear-resistant material and has waterproof properties, ensuring that it can maintain its original shape and size after long-term contact with different water qualities and underwater terrains, thereby ensuring exercise efficiency and service life.

[0088] The bracket 3 is composed of an arc-shaped cavity 12 for mounting the ball wheel 2 and a horizontally extending and backward-inclined portion 11 for mounting the bearing 10. The projections of the backward-inclined portion 11 and the arc-shaped cavity 12 in the vertical direction do not overlap or partially overlap. Such a staggered design makes the installation positions of the ball wheel 2 and the bearing 10 non-interfering with each other, and facilitates quick assembly and disassembly and maintenance of the ball wheel 2, the bracket 3, the bearing 10 and the connecting plate 9.

[0089] Therefore, the utility model has the advantages of durability, reliability, and convenient maintenance, so as to ensure that the water surface cleaning robot can operate efficiently and stably in various water environments.

[0090] like Figure 5 As shown, an embodiment of the working principle of the utility model:

[0091] The four ball wheels 2 evenly installed on the bottom of the water surface cleaning robot of the utility model can realize omnidirectional movement. When the water surface cleaning robot encounters a slope, the characteristics of the ball wheels 2 will affect its movement performance:

[0092] When the slope angle is less than or equal to 10°, the ball wheel 2 can help the water surface cleaning robot to move upward along the slope. Due to the continuous increase in power, the water surface cleaning robot stops after reaching the top of the slope, enters a reverse mode, and then slides down the slope.

[0093] The same thing happens when the slope angle exceeds 10°: the surface cleaning robot starts to move up the slope, but stops at the starting point of the slope, enters reverse mode, and then slides down the slope.

[0094] Therefore, the following situations will not occur: When encountering a slope, the machine will be unable to move forward or backward, causing the surface cleaning robot to be stranded. Figure 6 .

[0095] In the present application, the fixed connection method can be screw connection, welding, riveting, plug connection, or connection through a third component, and technical personnel in this field can choose according to actual conditions.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
