Abstract

The application discloses a water-leaving base station and a cleaning system, and relates to the technical field of cleaning robots. The water-leaving base station comprises a base station main body, a dragging and carrying mechanism and a bearing piece. The dragging and carrying mechanism is used for carrying a cleaning robot, and is movably connected with the base station main body. The dragging and carrying mechanism has a first position and a second position. The first position is a position where the dragging and carrying mechanism is at least partially located below a water surface. The second position is a position where the dragging and carrying mechanism is separated from the water surface. The bearing piece is rotatably connected with the base station main body. The bearing piece is located between the base station main body and the dragging and carrying mechanism. The dragging and carrying mechanism is in contact with the bearing piece and can be supported by the bearing piece. By arranging the bearing piece between the dragging and carrying mechanism and the base station main body of the cleaning robot, the abrasion between the dragging and carrying mechanism and the base station main body is reduced, so that the service life of the water-leaving base station is prolonged.

Description

Technical Field

[0001] This application relates to the field of cleaning robot technology, and more particularly to water-free base stations and cleaning systems. Background Technology

[0002] Cleaning robots are devices used to perform tasks such as cleaning, disinfecting, and rescuing in water tanks. They are widely used in various water tanks and other water storage environments. When performing tasks, cleaning robots need to enter the tank from a base station on the shore or return to the base station from the tank. Currently, during the process of leaving and entering the tank, the mechanism used to tow the cleaning robot is prone to wear and tear, which affects the service life of the towing mechanism. Utility Model Content

[0003] In view of this, this application provides a water-removing base station and a cleaning system, which reduces wear between the towing mechanism and the base station body by setting a load-bearing component between the cleaning robot and the base station body, thereby extending the service life of the water-removing base station.

[0004] In a first aspect, this application provides a water-removable base station, comprising a base station body, a towing mechanism, and a support member. The towing mechanism carries a cleaning robot and is movably connected to the base station body. The towing mechanism has a first position and a second position. The first position is where the towing mechanism is at least partially below the water surface, and the second position is where the towing mechanism is detached from the water surface. The support member is rotatably connected to the base station body and is located between the base station body and the towing mechanism. The towing mechanism contacts the support member and can be supported by the support member.

[0005] The water-removable base station provided in this application uses a support member between the towing mechanism and the base station body. During the movement of the towing mechanism relative to the base station body, the support member rolls against the towing mechanism, transforming sliding friction into rolling friction. This reduces the frictional force between the two, thereby mitigating wear on the towing mechanism and extending its service life. Furthermore, the support member supports the towing mechanism as it moves relative to the base station body, enhancing the stability and reliability between the towing mechanism and the base station body, making the operation of the water-removable base station safer.

[0006] In one possible implementation, the base station body has a groove at the end near the water surface, and the support component is disposed within the groove. By providing an inwardly recessed groove for the installation and replacement of the support component, it facilitates operation by staff. During long-term use of the base station away from water, only the support component needs to be replaced, without replacing the towing mechanism, which extends the service life of the towing mechanism and saves costs.

[0007] In one possible implementation, the carrier member at least partially protrudes from the groove, and the portion of the carrier member protruding from the groove makes rolling contact with the towing mechanism. This solution proposes a carrier member that can protrude from the groove. During the movement of the towing mechanism relative to the base station body, the protruding portion of the carrier member can make rolling contact with the towing mechanism, preventing friction between the towing mechanism and the end of the base station body, reducing wear on the base station body and the towing mechanism, and helping to extend the service life of the water-based base station.

[0008] In one possible implementation, the axis of the support member is positioned slightly downwards along the height direction of the end of the base station body closest to the water surface. Positioning the axis of the support member slightly downwards brings it closer to the bottom surface of the base station body. This results in a smaller lever arm for the support member when supporting the towing mechanism, thus reducing the gravitational torque on the base station body. This prevents the base station body from tipping over under the combined action of the towing mechanism and the pool cleaning machine, ensuring the stability of the base station body and extending its service life after it leaves the water.

[0009] In one possible implementation, the carrier includes a main body and two annular protrusions arranged opposite each other along the axial direction of the main body. The two annular protrusions are coaxially arranged with the main body, and their outer diameters are larger than the outer diameter of the main body. The towing mechanism includes at least two limiting parts located between the two annular protrusions along the axial direction of the carrier, with two of the limiting parts abutting against the two annular protrusions respectively. During the switching between a first position and a second position relative to the base station body, the limiting parts cooperate with the two annular protrusions to restrict the towing mechanism from moving horizontally relative to the base station body, preventing movement deviation between the towing mechanism and the base station body. Without limiting parts, the towing mechanism is prone to deviation or tipping relative to the base station body during movement, which not only affects the service life of the towing mechanism but also easily causes safety accidents.

[0010] In one possible implementation, the towing mechanism has opposing first and second ends, and the limiting portion extends to the first and second ends along a direction opposite to them. The side of the limiting portion facing the main body is used for rolling contact with the outer peripheral surface of the main body. Extending the length of the limiting portion of the towing mechanism to the opposing first and second ends of the towing mechanism ensures that the friction between the towing mechanism and the base station body is rolling friction during movement relative to the base station body, thereby reducing wear between the towing mechanism and the base station body. Furthermore, only the limiting portion of the towing mechanism makes rolling contact with the main body of the carrier, thus reducing the contact area between the towing mechanism and the main body, decreasing wear on other parts of the towing mechanism, further reducing wear between the towing mechanism and the base station body, and extending the service life of the towing mechanism.

[0011] In one possible implementation, the number of carriers includes two, which are spaced apart along the axial direction of the carrier and are used to make rolling contact with the towing mechanism. By providing at least two carriers, during the movement of the towing mechanism relative to the base station body, at least two carriers can make rolling contact with the towing mechanism, jointly supporting the towing mechanism, enhancing the stability and reliability between the towing mechanism and the base station body, and making the operation safer.

[0012] In one possible implementation, the towing mechanism includes a bottom wall, the side of which faces away from the base station body and is used to support the cleaning robot. A support member is located between the base station body and the bottom wall, and the support member is used for rolling contact with the bottom wall. By supporting the cleaning robot through the bottom wall of the towing mechanism, and by positioning the support member between the base station body and the bottom wall of the towing mechanism, friction between other parts of the towing mechanism and the base station body during use is reduced, thereby reducing wear on other parts of the towing mechanism and extending its service life.

[0013] In one possible implementation, the water-removable base station includes a drive mechanism, one end of which is connected to the towing mechanism, and the other end of which is connected to the base station body. The drive mechanism is used to drive the towing mechanism to move relative to the base station body. By setting a drive mechanism on the water-removable base station, the towing mechanism can move relative to the base station body under the action of the drive mechanism, replacing the inconvenience of manual operation by the user and making the operation process more convenient and safer.

[0014] In one possible implementation, when the towing mechanism is in the first position, the distance between the first end of the towing mechanism and the support member is less than the distance between the second end of the towing mechanism and the support member; when the towing mechanism is in the second position, the distance between the first end of the towing mechanism and the support member is greater than the distance between the second end of the towing mechanism and the support member. This design reduces the gravitational torque on the base station body when supporting the towing mechanism, preventing the base station body from tipping over under the combined action of the towing mechanism and the pool cleaning machine, ensuring the stability of the base station body, and extending the service life of the water-free base station.

[0015] Secondly, this application provides a cleaning system comprising a cleaning robot and the aforementioned water-removing base station, wherein the water-removing base station is used to support the cleaning robot. This solution provides a cleaning system in which the cleaning robot can automatically complete cleaning tasks with the water-removing base station in place, facilitating user operation. Furthermore, the water-removing base station can support the cleaning robot, saving workspace and promoting the rational use of workspace. Attached Figure Description

[0036] The possible embodiments of this application are described below with reference to the accompanying drawings.

[0037] The water-removable base station provided in this application embodiment is suitable for use in water tanks, swimming pools, etc., where cleaning of the water storage environment is involved during use. The water-removable base station provided in this application embodiment includes a base station body, a towing mechanism, and a support component. The base station body is fixedly installed, the towing mechanism is used to support cleaning equipment, such as cleaning robots or other automated equipment, and the support component is movably connected between the base station body and the towing mechanism. When the towing mechanism moves relative to the base station body, the support component and the towing mechanism make rolling contact, generating rolling friction between them, thereby reducing wear and tear and extending the service life of the towing mechanism.

[0038] Figure 1 This is a schematic diagram of an off-water base station provided in one embodiment of this application, with the towing mechanism in the first position. Figure 2 This is a schematic diagram of an off-water base station provided in one embodiment of this application, with the towing mechanism in the second position. Figure 3 This is a schematic diagram of an off-water base station provided in one embodiment of this application. (See also...) Figure 1 , Figure 2 and Figure 3As shown, the water-based base station 1000 includes a base station body 100, a towing mechanism 200, and a support member 300. The base station body 100 is fixedly installed on the shore. The support member 300 is installed on the side of the base station body 100 closest to the water surface and can be rotatably connected to the base station body 100. Simultaneously, the support member 300 can also be rotatably connected to the towing mechanism 200, thereby allowing the towing mechanism 200 to move relative to the base station body 100. The towing mechanism 200 carries the cleaning robot 10. When the cleaning robot 10 is cleaning the pool, the towing mechanism 200 leaves the base station body 100, adhering to the wall and located underwater. This state is the first position of the towing mechanism 200 relative to the base station body 100. The cleaning robot then leaves the towing mechanism 200 and enters the water to perform pool cleaning. After the cleaning work is completed, the cleaning robot 10 moves onto the towing mechanism 200 and returns to the base station body 100 under the drive of the towing mechanism 200. At this time, the towing mechanism 200 is located on the base station body 100, which is the second position of the towing mechanism 200 relative to the base station body 100. When the towing mechanism 200 switches between the first position and the second position relative to the base station body 100, the towing mechanism 200 moves relative to the base station body 100. The carrier 300 is located between the base station body 100 and the towing mechanism 300. The carrier 300 is rotatably connected to the base station body 100 and is used to rotate relative to the base station body 100 to move the towing mechanism 200 relative to the base station body 100. In one possible implementation, the carrier 300 may include, but is not limited to, a carrier wheel. In this application, the carrier 300 is described using a carrier wheel as an example.

[0039] The water-removable base station 1000 provided in this application uses a support member 300 between the towing mechanism 200 and the base station body 100. During the movement of the towing mechanism 200 relative to the base station body 100, the support member 300 rolls against the towing mechanism 200, changing sliding friction into rolling friction. This reduces the friction between the towing mechanism 200 and the base station body 100, thereby reducing wear and tear and extending the service life of the water-removable base station 1000. Furthermore, the support member 300 supports the towing mechanism 200 during its movement relative to the base station body 100, enhancing the stability and reliability between them and making the operation of the water-removable base station 1000 safer.

[0040] In one possible implementation, see [reference] Figure 1As shown, the base station body 100 has a slope 110 and an inclined base portion 120. From the side furthest from the water surface to the side closest to the water surface, the slope 110 of the base station body 100 is inclined, and the slope 110 is a smoothly transitioning surface. The base portion 120 of the base station body 100 can be fixed to the shoreline to prevent the base station body 100 from moving. A towing mechanism 200 can be connected to the base station body 100. The slope 110 of the base station body 100 supports the towing mechanism 200, placing the towing mechanism 200 in a second position. Furthermore, the slope 110 also facilitates the towing mechanism 200 switching from the second position to a first position.

[0041] In one possible implementation, see [reference] Figure 1 As shown, when the cleaning robot 10 enters the water to perform cleaning operations, the towing mechanism 200 adheres to the wall and can be completely submerged below the water surface. In one possible implementation, when the cleaning robot 10 enters the water to perform cleaning operations, the towing mechanism 200 adheres to the wall and can be partially submerged below the water surface.

[0042] Figure 3 This is a schematic diagram of an off-water base station provided in one embodiment of this application. Figure 4 This is a schematic diagram of a cleaning robot placed inside a water station according to one embodiment of this application. Figure 5 This is a schematic diagram of an off-water base station provided in one embodiment of this application, where no cleaning robot is placed. (See also...) Figure 3 , Figure 4 and Figure 5 As shown, in one possible implementation, the towing mechanism 200 includes a bottom wall 210 and a side wall 220. The side wall 220 is connected to the bottom wall 210 and together with the bottom wall 210 forms a receiving cavity 230. The receiving cavity 230 is in an open state and is used to receive the cleaning robot 10. It can also receive other cleaning equipment. The bottom wall 210 of the towing mechanism 200 is used to support the cleaning robot 10.

[0043] Continue reading Figure 5 As shown, in one possible implementation, the sidewall 220 of the towing mechanism 200 includes four sub-sidewalls facing different directions. The four sub-sidewalls are arranged opposite each other in pairs. The first sub-sidewall 221 and the third sub-sidewall 223 are arranged opposite each other, facing left and right respectively, while the second sub-sidewall 222 and the fourth sub-sidewall 224 are arranged opposite each other, facing front and back respectively. The first sub-sidewall 221, the second sub-sidewall 222, the third sub-sidewall 223 and the fourth sub-sidewall 224 are connected in sequence, and together with the bottom wall 210 of the towing mechanism 200, they form a receiving cavity 230.

[0044] In one possible implementation, the fourth sub-sidewall 224 may be in an open or closed state relative to the towing mechanism 200. When the fourth sub-sidewall 224 is in an open state relative to the towing mechanism 200, the cleaning robot 10 can extend into the accommodating cavity 230 from the water or extend out of the accommodating cavity 230 into the water to perform cleaning work. When the fourth sub-sidewall 224 is in a closed state relative to the towing mechanism 200, the cleaning robot 10 can return to the accommodating cavity 230 to stop cleaning work or the cleaning robot 10 can detach from the accommodating cavity 230 and enter the water to perform cleaning work.

[0045] Figure 6 This is a schematic diagram of the base station main body provided in one embodiment of this application, see reference. Figure 6 As shown, in one possible implementation, the inclination direction along the inclined surface 110 of the base station body 100 is the first direction; in this application, the first direction is the X direction. The base station body 100 includes an end portion 130. The end of the base station body 100 closest to the water surface is the end portion 130 of the base station body 100. Relative to the end portion 130, the base station body 100 also includes another end portion 140 on the side furthest from the water surface. Both ends are connected to the inclined surface 110 of the base station body 100. (Continue reading...) Figure 6 As shown, in one possible implementation, the end 130 of the base station body 100 is provided with a groove 131. The groove 131 is formed by the inward recess of the end 130, and the support member 300 is installed in the groove 131 for movably connecting the base station body 100. The end 130 is provided with a groove 131, and the support member 300 is disposed in the groove 131. The end 130 extends along the horizontal direction Y, and the groove 131 can be disposed at any position on the end 130. In one possible implementation, the end 130 includes at least two grooves 131, which are spaced apart along the horizontal direction Y of the end 130. In another possible implementation, the length of the groove 131 matches the length of the support member 300, allowing the support member 300 to be movably installed in the groove 131. Because the support member 300 can be movably installed, it is convenient for staff to replace the support member 300 in a timely manner. During the long-term use of the water-based base station 100, only the support member 300 needs to be replaced, without replacing the towing mechanism 200, which saves costs.

[0046] Figure 7 This is a schematic diagram illustrating the connection relationship between the carrier and the towing mechanism according to one embodiment of this application. (See attached diagram.) Figure 6 and Figure 7In one possible implementation, the carrier 300 at least partially protrudes from the groove 131, and the carrier 300 is rotatable relative to the groove 131. The portion of the carrier 300 protruding from the groove 131 is used for rolling contact with the towing mechanism 200. When the towing mechanism 200 moves relative to the base station body 100, the carrier 300 is in a rotating state relative to the groove 131. The bottom wall 210 of the towing mechanism 200 has a smoothly transitioned surface. When the towing mechanism 200 moves relative to the base station body 100, the carrier 300 is in a rotating state relative to the groove 131, allowing the carrier 300 to roll into contact with the bottom wall 210 of the towing mechanism 200, thus transforming the friction between the towing mechanism 200 and the base station body 100 into rolling friction, thereby reducing wear between the towing mechanism 200 and the base station body 100.

[0047] Understandably, when the towing mechanism 200 is in the second position relative to the base station body 100, the carrier 300 is fixed relative to the groove 131 and does not rotate relative to the base station body 100.

[0048] Figure 8 This is a schematic diagram of the main body of a base station provided in one embodiment of this application. Figure 9 yes Figure 8 The left view of the base station body shown. Figure 10 yes Figure 9 Enlarged view of section I in the middle. (See also...) Figure 8 , Figure 9 and Figure 10 As shown, in one possible implementation, the axis C of the support member 300 is positioned slightly downwards along the height direction of the end of the base station body 100 closest to the water surface. In another possible implementation, the distance between the axis C of the support member 300 and the bottom surface of the base station body 100 along the second direction is greater than half the length of the end portion 130 along the second direction and less than three-quarters of the length of the end portion 130 along the second direction, and the second direction is perpendicular to the axial direction of the support member 300. In this embodiment, the axial direction of the support member is the Y direction, and the second direction is the height direction of the base station body 100, which is the Z direction. Along the second direction Z, the distance from the axis C of the bearing member 300 to the bottom surface of the base station body 100 is L1, and the distance from the highest point of the end 130 of the base station body 100 to the bottom surface of the base station body 100, that is, the length of the end 130 along the second direction Z, is L2. L1 is greater than half of L2 and less than three-quarters of L2. Therefore, when supporting the towing mechanism, the lever arm of the bearing member is smaller, which makes the gravitational torque on the base station body smaller, preventing the base station body from tipping over under the action of the towing mechanism and the pool cleaning machine, and ensuring the stability of the base station body.

[0049] Figure 12 This is a schematic diagram of the driving mechanism of a base station body according to one embodiment of this application. (See also...) Figure 12 In one possible implementation, the water-based base station 1000 includes a drive mechanism 400, which may include a linkage transmission mechanism 410. The axis of the linkage transmission mechanism 410 connected to one end of the side wall 220 of the towing mechanism 200 is point A, the bottom end of the other end of the towing mechanism 200 relative to point A is point B, and the contact point between the bottom wall 210 of the towing mechanism 200 and the carrier 300 is point D. During the process of the linkage transmission mechanism 410 driving the towing mechanism 200 to change from the first position to the second position, as the towing mechanism 200 gradually moves onto the base station body 100, the straight-line distance AD ​​from point A to point D is greater than the straight-line distance BD from point B to point D. When supporting the towing mechanism 200, the axis C of the bearing member 300 is set slightly lower along the height direction of the end of the base station body 100 near the water surface (end 130). Compared with the axis C being set slightly higher, the straight-line distance BD is shorter, and the lever arm of the bearing member 300 is smaller, thus making the gravitational torque on the base station body smaller. This helps the towing mechanism 200 to flip around point D as the rotation point, preventing the base station body from tipping over under the action of the towing mechanism and the pool cleaning machine, ensuring the stability of the base station body, and helping to extend the service life of the water-free base station.

[0050] Continue reading Figure 8 and Figure 9 As shown, in one possible embodiment, the carrier 300 includes a main body 310. The horizontal direction Y of the end 130 of the base station main body 100 is in the same direction as the axial direction of the main body 310 of the carrier 300. Along the axial direction of the main body 310 of the carrier 300, the carrier 300 also includes two opposing annular protrusions 320. The two annular protrusions 320 are respectively disposed at both ends of the main body 310 of the carrier 300, and the outer diameter of the two annular protrusions 320 is larger than the outer diameter of the main body 310. In one possible embodiment, the main body 310 and the two annular protrusions 320 are integrally formed to form the carrier. In another possible embodiment, the radius of the main body 310 is less than or equal to the radius of the groove 131, so that the groove 131 can accommodate the main body 310 of the carrier 300, and the outer diameter of the two annular protrusions 320 can protrude from the groove 131. When the carrier 300 is rotating relative to the groove 131, the two annular protrusions 320 can roll into contact with the bottom wall of the towing mechanism 200.

[0051] Figure 11 This is a schematic diagram illustrating the connection relationship between the carrier and the towing mechanism according to one embodiment of this application. See further... Figure 11As shown, the towing mechanism 200 includes a limiting portion 240, and the number of limiting portions 240 is at least two. At least two limiting portions 240 are located between two annular protrusions 320 along the axial direction of the carrier member 300, wherein the two limiting portions 240 are respectively used to abut against the two annular protrusions 320. During the switching process of the towing mechanism 200 relative to the base station body 100 in a first position and a second position, the limiting portions 240 cooperate with the two annular protrusions 320 to restrict the movement of the towing mechanism 200 relative to the base station body 100 in the horizontal direction Y.

[0052] In one possible implementation, there are two limiting portions 240, including a first limiting portion 241 and a second limiting portion 242 spaced apart along the axial direction of the support member 300. Along the axial direction of the support member 300, the first limiting portion 241 and the second limiting portion 242 are located between two annular protrusions 320 of the support member 300. The first limiting portion 241 abuts against one annular protrusion 320 of the support member 300, and the second limiting portion 242 abuts against the other annular protrusion 320 of the support member 300. See also [link to another possible implementation]. Figure 11 As shown, the towing mechanism 200 includes four limiting parts 240. Along the axial direction of the carrier 300, the four limiting parts 240 are arranged sequentially at intervals. Two of the limiting parts 240 abut against two annular protrusions 320 respectively, and the two middle limiting parts 240 are located between the limiting parts 240 that abut against the two annular protrusions 320.

[0053] In one possible implementation, the towing mechanism 200 has a first end and a second end disposed opposite to each other. A limiting portion 240 extends to the first end and the second end along the direction in which the first end and the second end are disposed opposite to each other. The side of the limiting portion 240 facing the main body 310 is used for rolling contact with the outer peripheral surface of the main body 310. In this application, the limiting portion 240 is disposed on the bottom wall 210 of the towing mechanism 200. During the movement of the towing mechanism 200 relative to the base station body 100, the surface of the limiting portion 240 facing the main body 310 rolls in contact with the outer peripheral surface of the main body 310 until the towing mechanism 200 is completely on the base station body 100 or the towing mechanism is completely detached from the base station body 100. The rolling contact between the limiting portion 240 and the main body 310 transforms the friction between the towing mechanism 200 and the base station body 100 into rolling friction, thereby reducing wear between the towing mechanism 200 and the base station body 100. Without a limiting part, the towing mechanism 200 is prone to shifting or tipping over relative to the base station body 100 during movement, which not only affects its service life but also increases the risk of safety accidents. Furthermore, the limiting part 240 reduces the contact area of ​​other parts of the towing mechanism 200, thereby reducing the contact area between the towing mechanism 200 and the base station body 100, decreasing wear on other parts of the towing mechanism 200, further reducing wear between the towing mechanism 200 and the base station body 100, and extending the service life of the towing mechanism 200.

[0054] In one possible implementation, the number of carrier members 300 includes two, which are spaced apart along the axial direction of the carrier members 300, and are used for rolling contact with the towing mechanism 200. Taking two carrier members 300 as an example, see [reference needed]. Figure 6As shown, two grooves 131 are provided on the end 130 of the base station body 100, and the two grooves 131 are spaced apart along the axial direction of the support member 300. The support member 300 includes a first support member 301 and a second support member 302. Along the axial direction of the support member 300, the first support member 301 and the second support member 302 are respectively disposed in the grooves 131 on the end 130 of the base station body 100, and the first support member 301 and the second support member 302 are symmetrically arranged. When the towing mechanism 200 moves relative to the base station body 100, the first support member 301 and the second support member 302 jointly roll in contact with the bottom wall 210 of the towing mechanism 200, reducing the wear between the base station body 100 and the towing mechanism 200, and jointly supporting the towing mechanism 200, enhancing the stability and reliability between the towing mechanism 200 and the base station body 100, and making the operation process safer. In one possible implementation, the number of carrier members 300 includes one, which is disposed at the center of the end 130 of the base station body 100 along the axial direction of the carrier member 300, and the carrier member 300 is used for rolling contact with the towing mechanism 200. In another possible implementation, the number of carrier members 300 includes three, four, etc., with multiple carrier members 300 evenly spaced along the axial direction of the carrier member 300, and the multiple carrier members 300 are used for rolling contact with the towing mechanism 200.

[0055] Figure 12 This is a schematic diagram of the driving mechanism of a base station body according to one embodiment of this application. (See also...) Figure 12 In one possible implementation, the water-based base station 1000 includes a drive mechanism 400, which includes a drive motor and a linkage transmission mechanism 410. The drive motor is mounted on the base portion 120 of the base station body 100. One end of the linkage transmission mechanism 410 is connected to the base portion 120 of the base station body 100, and the other end of the linkage transmission mechanism 410 is connected to the side wall 220 of the towing mechanism 200. The drive motor drives the linkage transmission mechanism 410 to move, which can drive the towing mechanism 200 to move, so that the towing mechanism 200 is in a first position or a second position relative to the base station body 100. The drive mechanism 400 can replace the inconvenience of manual operation by the user, making the operation process more convenient and safer.

[0056] In one possible implementation, the other end of the linkage mechanism 410 may be connected to the second sub-sidewall 222 of the towing mechanism 200. In another possible implementation, the other end of the linkage mechanism 410 may be connected to other sub-sidewalls of the towing mechanism 200.

[0057] Continue reading Figure 12As shown, in one possible implementation, the carrier 300 protrudes from the groove 131 and contacts the bottom wall 210 of the towing mechanism 200. The contact point between the bottom wall 210 and the carrier 300 is point D. The bottom end of the towing mechanism 200 is point B. The other end of the towing mechanism 200, which is located opposite to point B, is point E. The end where point E is located is the first end of the towing mechanism 200, and the end where point B is located is the second end of the towing mechanism 200. The first end and the second end are arranged opposite to each other. At least part of the towing mechanism 200 is located below the water surface. When in the first position, the straight-line distance ED from point E to point D is less than the straight-line distance BD from point B to point D. When the towing mechanism 200 is in the second position, the straight-line distance ED from point E to point D is greater than the straight-line distance BD from point B to point D. That is, during the movement of the towing mechanism 200 from the first position to the second position, it rotates around point D as the rotation point. As the towing mechanism 200 moves towards the base station body 100 in a direction away from the water surface, the straight-line distance ED from point E to point D gradually increases, and the straight-line distance BD from point B to point D gradually decreases. The lever arm of the bearing member 300 is smaller, which makes the gravitational torque on the base station body smaller. This helps the towing mechanism 200 to rotate around point D as the rotation point, avoids the base station body from tipping over under the action of the towing mechanism and the pool cleaning machine, ensures the stability of the base station body, and helps extend the service life of the base station away from the water.
