[0044] As Figure 1As shown, this application provides an automatic water surface cleaning device 100, which can remove debris from water bodies, protect the aquatic ecological environment, improve water cleanliness, and reduce water pollution. For example, the automatic water surface cleaning device 100 can use suction and a screen to collect and process debris such as aquatic plants, floating objects, and garbage in the water, thereby maintaining water cleanliness. During operation, the automatic water surface cleaning device 100 of this application can avoid stranding and prevent accidental injury to the operator.

[0045] The automatic water surface cleaning device 100 includes a main body 110 and an anti-sanding device 120 connected to the main body 110. The anti-sanding device 120 is used to prevent the main body 110 from getting stuck. The anti-sanding device 120 is located at the bottom of the main body 110.

[0046] like Figure 1 As shown, the automatic water surface cleaning device 100 includes at least two anti-sanding devices 120, which are spaced apart. The at least two anti-sanding devices 120 can be respectively installed on both sides of the main body 110. The symmetrical arrangement of the anti-sanding devices 120 provides stable support for the main body 110 and maintains the balance of the automatic water surface cleaning device 100.

[0047] The anti-stranding device 120 is at least partially disposed on the bottom of the main body 110. As an alternative embodiment, a portion of the anti-stranding device 120 is disposed on the bottom of the main body 110, while another portion can be located outside the main body 110. As another alternative embodiment, the entire anti-stranding device 120 is disposed on the bottom of the main body 110. The entire anti-stranding device 120 can be located within the bottom of the main body 110. The anti-stranding device 120 is rotatable relative to the main body 110.

[0048] Furthermore, such as Figures 5 to 8 As shown, the anti-stranding device 120 includes a first end 121 and a second end 122, which are located at opposite ends of the device. The first end 121 and the second end 122 are located at opposite ends of the anti-stranding device 120 along its length. The first end 121 has a generally arc-shaped structure. It is located at the bottom of the main body 110. The first end 121 is hinged to the main body 110. It is rotatably connected to the main body 110 and can rotate about its axis of rotation. The second end 122 is a free end and can rotate relative to the bottom of the main body 110. The second end 122 can drive the first end 121 to rotate. It can also rotate about its axis of rotation.

[0049] As an alternative implementation method, such as Figure 1 and Figure 4As shown, the second end 122 is at least partially protruded from the bottom of the main body 110. For the convenience of observation, Figure 1 , Figure 4 , Figure 9 and Figure 11 , the bottom of the water surface automatic cleaning device 100 is toward the upper side of the page, and the top of the water surface automatic cleaning device 100 is toward the lower side of the page. Specifically, the second end 122 is entirely protruded from the bottom of the main body 110. Alternatively, part of the second end 122 is protruded from the bottom of the main body 110, and the other part is accommodated in the bottom of the main body 110. Preferably, the second end 122 is protruded from the bottom of the main body 110 along the height direction of the water surface automatic cleaning device 100. The second end 122 is protruded from the main body 110 to prevent the water surface automatic cleaning device 100 from grounding.

[0050] The operator can rotate the anti-grounding device 120 by operating the second end 122, which can not only achieve the anti-grounding function but also be accommodated in the main body 110, and the operation is simple and convenient.

[0051] As shown in Figure 7 and Figure 8 , in order to facilitate manual operation by the operator, the second end 122 is provided with a protruding part 136 for hand operation. The protruding part 136 is protruded from the second end 122. The protruding part 136 is protruded from the second end 122 in a direction away from the first end 121. The protruding part 136 is spaced apart from the main body 110. The protruding part 136 is spaced apart from the main body 110 along the height direction of the water surface automatic cleaning device 100. In the embodiments of the present disclosure, as shown in Figure 10 and Figure 12 , in order to make the protruding part 136 easy to hold, the bottom of the main body 110 is provided with a groove 137. The groove 137 is spaced apart from the protruding part 136 along the height direction of the water surface automatic cleaning device 100. When the second end 122 is accommodated in the bottom of the main body 110, the groove 137 is opposite to the protruding part 136. In this way, the operator can directly hold the protruding part 136 of the second end 122 to rotate the second end 122 around the first end 121, which is simple and convenient to operate and can avoid hurting the operator during operation.

[0052] The water surface automatic cleaning device 100 according to the present application comprises a main body 110 and an anti-grounding device 120, the anti-grounding device 120 is located at the bottom of the main body 110, the anti-grounding device 120 comprises a first end 121 and a second end 122, the first end 121 is arranged at the bottom of the main body 110, the second end 122 is a free end, and the second end 122 can rotate relative to the bottom of the main body 110. In this way, the anti-grounding device 120 can rotate relative to the bottom of the main body 110, the anti-grounding device 120 can realize the anti-grounding function, can be stored in the main body 110, is simple and convenient to operate, and can avoid being stuck and can avoid hurting the operator.

[0053] As shown in Figure 6 and Figure 7 shown, in order to facilitate rotation of the second end 122, the first end 121 of the anti-grounding device 120 is provided with a rotating shaft 123, the rotating shaft 123 can be connected to the main body 110. The first end 121 is connected to the main body 110 through the rotating shaft 123. The rotating shaft 123 is used to connect the anti-grounding device 120 and the main body 110. The axial direction of the rotating shaft 123 is parallel to the width direction of the water surface automatic cleaning device 100. The rotating shaft 123 is arranged in the first end 121, and both ends of the rotating shaft 123 are connected to the main body 110.

[0054] Further, as shown in Figure 5 , the first end 121 is provided with a hinge hole 124, and the rotating shaft 123 is arranged in the hinge hole 124. The hinge hole 124 penetrates the first end 121 along the width direction of the anti-grounding device 120. Both ends of the rotating shaft 123 protrude out of the hinge hole 124 along the width direction of the anti-grounding device 120.

[0055] Both ends of the rotating shaft 123 are connected to the main body 110. The rotating shaft 123 penetrates the first end 121 and is connected to the main body 110. The rotating shaft 123 penetrates the first end 121 along the axial direction of the rotating shaft 123. The first end 121 is sleeved to the outside of the rotating shaft 123 through the hinge hole 124. The axial direction of the hinge hole 124 is parallel to the axial direction of the rotating shaft 123. The first end 121 can rotate relative to the main body 110. In the embodiment of the present disclosure, the rotating shaft 123 and the main body 110 can be fixed together, the first end 121 can rotate relative to the rotating shaft 123, and the anti-grounding device 120 rotates as a whole. In the embodiment of the present disclosure, the first end 121 and the rotating shaft 123 are fixed together, the rotating shaft 123 can rotate relative to the main body 110, thereby driving the first end 121 to rotate, and the anti-grounding device 120 rotates as a whole.

[0056] The operator rotates the first end 121 by operating the second end 122 of the anti-grounding device 120. The second end 122 rotates about the rotation axis 123. The second end 122 rotates about the rotation axis 123 between a first position and a second position. The second end 122 in the first position is rotatable to the second position. The second end 122 in the second position is rotatable to the first position.

[0057] For example, the second end 122 in the second position is rotatable clockwise about the rotation axis 123 to the first position. In combination with Figure 4 As shown, the second end 122 protrudes from the bottom of the main body 110 when the second end 122 is in the first position. The anti-grounding device 120 is rotatable about the rotation axis 123 to 90°. The anti-grounding device 120 in the first position can be perpendicular to the bottom plane of the main body 110. The second end 122 in the first position is outside the main body 110.

[0058] The second end 122 in the first position is also rotatable to the second position. For example, the second end 122 in the first position is rotatable counterclockwise about the rotation axis 123 to the second position. The second end 122 can be engaged with or abut against the bottom of the main body 110 when the second end 122 is in the second position.

[0059] The second end 122 can be engaged with or abut against the bottom of the main body 110 when the second end 122 is in the second position. The second end 122 in the second position can be engaged with the bottom of the main body 110 along the length direction of the anti-grounding device 120. For example, the second end 122 in the second position is located at the bottom of the main body 110 and can be engaged with the bottom of the main body 110. The bottom of the main body 110 can limit the rotation of the second end 122 in the second position.

[0060] For another example, the second end 122 can abut against the bottom of the main body 110 when the second end 122 is in the second position. The second end 122 in the second position can abut against the bottom of the main body 110 along the length direction of the anti-grounding device 120. The second end 122 in the second position is located at the bottom of the main body 110 and can abut against the bottom of the main body 110. The bottom of the main body 110 exerts a force on the second end 122 in the second position to limit the rotation of the second end 122 in the second position.

[0061] Further, in order to avoid excessive rotation of the anti-grounding device 120, the anti-grounding device 120 can be provided with a stopper 124. Figures 5 to 7As shown, the first end 121 comprises a first limiting portion 126 to prevent the first end 121 from rotating excessively. The first limiting portion 126 protrudes from the first end 121. The first limiting portion 126 protrudes outwardly along the length direction of the anti-grounding device 120. The second end 122 rotates to rotate the first end 121 around the rotation shaft 123. The first end 121 rotates to rotate the first limiting portion 126 around the rotation shaft 123. Preferably, the first limiting portion 126 can limit the maximum rotation angle of the anti-grounding device 120 to 90°. When the second end 122 is in the first position, the first limiting portion 126 engages or abuts with the main body 110, so as to fix the second end 122.

[0062] As shown in FIG. 1, the main body 110 comprises a first end 121 and a second end 122. The first end 121 is connected to the second end 122. The first end 121 is rotatable relative to the second end 122. The first end 121 is rotatable around a rotation shaft 123. The rotation shaft 123 is located between the first end 121 and the second end 122. The rotation shaft 123 is parallel to the water surface. The rotation shaft 123 is perpendicular to the height direction of the water surface automatic cleaning device 100. The rotation shaft 123 is perpendicular to the length direction of the anti-grounding device 120. Figure 11 Figure 12 As shown, the main body 110 comprises a first end 121 and a second end 122. The first end 121 is connected to the second end 122. The first end 121 is rotatable relative to the second end 122. The first end 121 is rotatable around a rotation shaft 123. The rotation shaft 123 is located between the first end 121 and the second end 122. The rotation shaft 123 is parallel to the water surface. The rotation shaft 123 is perpendicular to the height direction of the water surface automatic cleaning device 100. The rotation shaft 123 is perpendicular to the length direction of the anti-grounding device 120.

[0063] The first end 121 in the second position rotates towards the first position, which can rotate the first limiting portion 126 towards the direction of the second limiting portion 127. The first end 121 in the second position rotates towards the first position, which can rotate the first limiting portion 126 towards the direction of the main body 110. The second limiting portion 127 can engage or abut with the first end 121 in the first position. Thus, the second limiting portion 127 can position the first limiting portion 126. The second limiting portion 127 and the first limiting portion 126 limit the rotation angle of the anti-grounding device 120.

[0064] As an optional embodiment, when the second end 122 is in the first position, the first limiting portion 126 can engage with the second limiting portion 127. The first limiting portion 126 is located in the second limiting portion 127 at the bottom of the main body 110. The first limiting portion 126 of the first end 121 engages with the second limiting portion 127 of the main body 110. In this way, the first end 121 engages with the main body 110, and the first end 121 is fixed, so as to fix the second end 122.

[0065] ​In another alternative implementation, when the second end 122 is in the first position, the first limiting portion 126 can abut against the second limiting portion 127. The first limiting portion 126 is located within the second limiting portion 127 at the bottom of the main body 110. The first limiting portion 126 and the second limiting portion 127 abut against each other along the length direction of the automatic water surface cleaning device 100. The first limiting portion 126 and the second limiting portion 127 abut against each other along the outer surfaces of the automatic water surface cleaning device 100, restricting the rotation of the first limiting portion 126. The first limiting portion 126 of the first end 121 abuts against the second limiting portion 127 of the main body 110, fixing the first end 121 in place, thereby fixing the second end 122 in place.

[0066] Furthermore, in order to allow the anti-sanding device 120 to be stored at the bottom of the main body 110, such as... Figure 9 and Figure 10 As shown, the bottom of the main body 110 also includes a receiving groove 111. The receiving groove 111 is constructed as a generally rectangular recess. The receiving groove 111 is recessed along the height direction of the main body 110 from the bottom of the main body 110 toward the interior of the main body 110. The anti-stranding device 120 is connected to the main body 110 through the receiving groove 111. At least a portion of the anti-stranding device 120 can be located in the receiving groove 111. The receiving groove 111 is used to receive at least a portion of the anti-stranding device 120.

[0067] As an alternative implementation, the receiving groove 111 can accommodate a portion of the anti-sanding device 120. A portion of the anti-sanding device 120 can be accommodated in the receiving groove 111, while another portion can be located outside the main body 110. A first end 121 of the anti-sanding device 120 is located in the receiving groove 111. A second end 122 can protrude from the bottom of the main body 110. For example, the second end 122 can protrude from the receiving groove 111. The second end 122 located in the first position can be located outside the receiving groove 111.

[0068] In another alternative embodiment, the receiving groove 111 is capable of accommodating the entire anti-sanding device 120. The entire anti-sanding device 120 is located within the receiving groove 111. The first end 121 of the anti-sanding device 120 is located within the receiving groove 111. The second end 122, located in a second position, can be accommodated within the receiving groove 111. Thus, the entire first end 121 and the second end 122 of the anti-sanding device 120 can be located within the receiving groove 111, ensuring that the entire anti-sanding device 120 is contained within the receiving groove 111.

[0069] The first limiting part 126 protrudes from the first end 121, and the second limiting part 127 is arranged in the recess of the accommodating groove 111 to ensure sufficient limiting distance. The second limiting part 127 is recessed inward from the bottom surface of the accommodating groove 111. The second limiting part 127 is recessed inward from the bottom surface of the accommodating groove 111 along the height direction of the water surface automatic cleaning device 100. When the second end 122 is rotated to the first position, the first limiting part 126 and the second limiting part 127 can normally engage or abut, and the anti-grounding device 120 can protrude from the bottom of the main body 110, thereby realizing the anti-grounding function. At the same time, when the second end 122 is rotated to the second position, the anti-grounding device 120 can be accommodated in the accommodating groove 111, thereby avoiding the anti-grounding device 120 from being bumped.

[0070] Further, as shown in Figure 5 、 Figure 7 and Figure 10 , when the second end 122 is rotated to the second position, the anti-grounding device 120 is accommodated in the main body 110. The bottom of the main body 110 or the second end 122 comprises a locking part 128, which can make the second end 122 of the anti-grounding device 120 engage or abut with the bottom of the main body 110. The second end 122 is tightly engaged or abutted with the main body 110, thereby avoiding the second end 122 from easily separating from the main body 110 due to external shaking or the like, and thereby avoiding the anti-grounding device 120 from accidentally falling during normal operation.

[0071] In the embodiment of the present disclosure, the second end 122 comprises a locking part 128 located at the side of the second end 122. The locking part 128 protrudes from the second end 122. The locking part 128 can be engaged with the accommodating groove 111.

[0072] In order to avoid the locking part 128 interfering with the rotation of the anti-grounding device 120, the accommodating groove 111 is provided with a locking hole 135. The locking hole 135 can be a hole or a groove. The locking hole 135 and the locking part 128 can be engaged or abutted. The locking hole 135 is recessed from the inner surface of the accommodating groove 111 in a direction away from the anti-grounding device 120.

[0073] When the second end 122 is rotated to the second position, the locking part 128 can be engaged with the locking hole 135, the locking hole 135 prevents the locking part 128 from moving, thereby preventing the second end 122 from moving, and avoiding the second end 122 from separating from the main body 110.

[0074] When the second end 122 is rotated to the second position, the locking part 128 can abut with the locking hole 135, thereby limiting the rotation of the second end 122, and avoiding the second end 122 from separating from the main body 110.

[0075] When the second end 122 of the anti-grounding device 120 is in the second position, the locking hole 135 can accommodate at least a portion of the locking portion 128. In embodiments of the present disclosure, a portion of the locking portion 128 can be located in the locking hole 135, and another portion can protrude from the locking hole 135. In embodiments of the present disclosure, the locking hole 135 can accommodate the entire locking portion 128.

[0076] One or more locking portions 128 can be provided on both sides of the second end 122. One or more locking holes 135 can be provided on both sides of the accommodation slot 111. The plurality of locking holes 135 are symmetrically arranged along the width direction of the accommodation slot 111. The at least one locking column and the at least one locking hole can be engaged or abutted with each other. In this way, the second end 122 can be more firmly connected to the bottom of the main body 110, avoiding disconnection of the second end 122 from the main body 110, so that the second end 122 can be closely accommodated in the bottom of the main body 110.

[0077] As shown in Figure 1 and Figure 2 The anti-grounding device 120 is located at the head or tail of the water surface automatic cleaning device 100. As an alternative embodiment, the anti-grounding device 120 is arranged at the head of the water surface automatic cleaning device 100, so that the operator can timely observe the working state of the anti-grounding device 120 and whether the grounding early warning is triggered. The anti-grounding device 120 can contact the shoal or obstacle in advance. The anti-grounding device 120 can bear part of the impact force when the head contacts the shoal or obstacle, to a certain extent, reducing the damage of important equipment or structure at the front end. As another alternative embodiment, the anti-grounding device 120 is located at the tail of the water surface automatic cleaning device 100. The anti-grounding device 120 can effectively protect the propulsion system from damage by the shoal or underwater obstacle.

[0078] The water surface automatic cleaning device 100 further comprises a power device, which is at least partially located inside the water surface automatic cleaning device 100. The power device can provide power to drive the water surface automatic cleaning device 100 to move on the water surface. For example, Figure 1 and Figure 10As shown, the power device includes a motor and a paddle 131. The paddle 131 is used to provide driving force for the water surface automatic cleaning device 100. The motor and the paddle 131 are located on one side of the water surface automatic cleaning device 100 along the length direction of the water surface automatic cleaning device 100. The motor drives the paddle 131 to rotate, and the paddle 131 exerts a backward force on the water, which in turn exerts a forward reaction force on the paddle 131, thereby pushing the water surface automatic cleaning device 100 to move on the water surface. In order to enable the power device to provide balanced power for the water surface automatic cleaning device 100, the water surface automatic cleaning device 100 is provided with at least two motors and at least two paddles 131. The at least two paddles 131 are arranged at intervals. The at least two paddles 131 are arranged at intervals along the width direction of the water surface automatic cleaning device 100. The at least two motors respectively provide power for the at least two paddles 131 to drive the water surface automatic cleaning device 100 to move smoothly.

[0079] As shown, Figure 4 The water surface automatic cleaning device 100 further includes a filtering device 132, which is used to filter impurities in water. The filtering device 132 is located inside the water surface automatic cleaning device 100. The filtering device 132 can have filter screen filtering, sedimentation filtering, biological filtering, etc. Filter screen filtering usually uses a filter screen with a certain pore size to remove large-particle impurities, suspended solids, hair and other visible solid substances in water. The water surface automatic cleaning device 100 usually introduces the water to be cleaned into the filtering device 132 through a water pump or other water inlet device. The filtering device 132 performs filtering treatment on the water to be cleaned, such as coarse filtering, fine filtering, adsorption filtering, etc. The water treated by the filtering device 132 has a significantly reduced content of impurities and pollutants, and after reaching a certain water quality standard, it will be discharged back into the water body.

[0080] As shown, Figure 3 The water surface automatic cleaning device 100 further includes a water inlet and a water outlet. The water inlet is used for water inlet, and the water outlet is used for water outlet. The water inlet and the water outlet are located on the outer surface of the water surface automatic cleaning device 100. The water flows from the water inlet into the water surface automatic cleaning device 100, and is discharged from the water outlet to the outside of the water surface automatic cleaning device 100 after passing through the filtering device 132. The water flow can flow from the water inlet into the water surface automatic cleaning device 100. The filtering device 132 is arranged between the water inlet and the water outlet. The water inlet is in communication with the filtering device 132. The filtering device 132 is in communication with the water outlet. The water inlet is in communication with the water outlet through the filtering device 132. The water flow flows from the water inlet to the water outlet through the filtering device 132. The water outlet can discharge the water purified by the filtering device 132 to the water area outside the water surface automatic cleaning device 100. The water surface automatic cleaning device 100 can move through the power device, so that the water flow passes through the filtering device 132 from the water inlet to the water outlet, thereby making the cleaned water flow into the water area outside the water surface automatic cleaning device 100.

[0081] The water surface automatic cleaning device 100 further comprises a control system, which comprises sensors and a controller. The sensors comprise water level sensors, garbage detection sensors, etc. The water level sensors can monitor the height changes of the water surface around the device, ensure that the device works within a safe water level range, and can adjust the working state of the device according to the water level changes. The garbage detection sensors can detect the position and size of the garbage on the water surface, thereby guiding the device to effectively collect the garbage. The controller receives signals from the sensors and controls the working of components such as the power system and the garbage collecting device according to the preset program. The controller can be a simple single-chip microcomputer or a complex programmable logic controller.

[0082] As shown in Figure 11 and Figure 12 The water surface automatic cleaning device 100 further comprises an alarm device 133. The alarm device 133 is electrically connected with the anti-grounding device 120. The alarm device 133 can timely feedback the working state of the anti-grounding device 120. The alarm device 133 can generate an alarm signal, which can be transmitted to the control system, and through the analysis and processing of the control system, an alarm can be issued to warn the operator.

[0083] The electrical connection can be hard-wired connection, wireless connection, bus connection, etc. The mechanical connection can be mechanical transmission component connection or mechanical contact connection, etc. The fluid connection can be hydraulic connection or pneumatic connection, etc. The optical connection can be optical fiber sensing technology connection or infrared induction connection, etc. Other connection methods can be acoustic connection or chemical connection, etc. In the present embodiment, the connection of the alarm device 133 with the anti-grounding device 120 is the required connection method.

[0084] Preferably, the alarm device 133 is located in the second limiting portion 127. When the water surface automatic cleaning device 100 is working, if the second end 122 of the anti-grounding device 120 does not rotate to the second position, the alarm device 133 issues an alarm. When the water surface automatic cleaning device 100 is working, the anti-grounding device 120 is not completely accommodated in the accommodating groove 111. The alarm device 133 detects that the second end 122 is not in place, and then issues an alarm signal to warn that the anti-grounding device 120 protrudes from the main body 110.
