Optionally, the driving mechanism 3 is provided at the rear part of the main body 1.The water surface cleaning robot further includes an upper cover 4 slidably provided on the top of the main body 1 and slidable between a closed position and an open position. When the top cover 4 is in the closed position, the top cover 4 blocks the cavity 11 and the user cannot pull out the waste chamber 2 from the cavity 11, and when the top cover 4 is in the open position, the user can pull out the waste chamber 2 from the cavity 11.The top cover 4 is slidably connected to the main body 1, and the opening and closing of the cavity 11 is achieved by the structure of the slidable top cover 4, which not only facilitates the removal of the garbage chamber 2 but also minimizes the leverage at the connection between the top cover 4 and the main body 1, so that it is not liable to accidental damage, which contributes to extending the life of the water surface cleaning robot.In conjunction with FIGS. 1 to 4, a first limiting structure 431 is provided on the top cover 4, a second limiting structure 15 that cooperates with the first limiting structure 431 is provided on the main body 1, wherein the first limiting structure 431 is a plug block, the second limiting structure 15 is a plug hole, and the plug block is provided along the sliding direction of the top cover 4; or the first limiting structure 431 is a plug hole, the second limiting structure 15 is a plug block, and the plug block is provided along the sliding direction of the top cover 4. The cooperation between the plug block and the plug hole can prevent the upper cover 4 from being displaced in the vertical direction, which contributes to securing the structural stability of the water surface cleaning robot.Specifically, the second limiting structures 15 are respectively provided on the two opposite side walls of the cavity 11, and at least two first limiting structures 431 are provided on the top cover 4, wherein a part of the first limiting structures 431 cooperates with the second limiting structures 15 on one side wall of the cavity 11 and the other part of the first limiting structures 431 cooperates with the second limiting structures 15 on the other side wall of the cavity 11. Preferably, a seat body 43 is provided on the upper cover 4, and the front and rear sides of the seat body 43 are each provided with the first limiting structure 431. Further preferably, a side wall of the cavity 11 has an escape groove 16 for escaping the seat body 43, so that a greater degree of opening and closing of the upper cover 4 can be achieved. Regardless of whether the top cover 4 is in the closed or opened position, the position of the top cover 4 can be limited, thereby more completely preventing the top cover 4 from being displaced in the vertical direction.In conjunction with FIGS. 3 and 4, in the present embodiment, the upper cover 4 is provided with a guide rod 41, the main body 1 is provided with a guide sleeve 13, and the guide rod 41 cooperates with the guide sleeve 13 to enable slidable connection of the upper cover 4 to the main body 1; preferably, a recess for receiving the guide rod 41 is provided on the main body 1, and the guide sleeve 13 is provided in the recess. The provision of the recess can save space and make it possible to make the water surface cleaning machine smaller. At the same time, the recess can take over to some extent the role of protecting the guide rod 41. In other embodiments, the main body 1 is provided with a guide rod 41 and the top cover 4 is provided with a guide sleeve 13, and the guide rod 41 cooperates with the guide sleeve 13 to enable slidable connection of the top cover 4 to the main body 1. The cooperation between the guide rod 41 and the guide sleeve 13 allows the top cover 4 to slide linearly between the closed and opened positions, making the operation more comfortable and smoother for the user and contributing to an improvement in the user experience.It is to be understood that in one embodiment, the main body 1 is provided with at least two sets of guide sleeves 13, and that when the two ends of the guide rod 41 are respectively moved and locked to the corresponding sets of guide sleeves, the position of the upper cover 4 is limited, and due to the interaction between the guide sleeves 13 and the guide rod 41, the displacements of the upper cover 4 other than the movement along the extending direction of the guide rod 41 are limited. Specifically, the upper cover 4 is provided with a recess for receiving the guide rod 41, and the guide sleeve 13 is provided protruding from the main body 1.Specifically, as shown in FIG. 5, a controller is provided inside the main body 1, the controller being electrically connected to the drive mechanism 3. Optionally, the drive mechanism 3 comprises a drive motor and a propeller 31, the output end of the drive motor being connected to the propeller 31 and the controller being electrically connected to the drive motor.As shown in FIG. 6, the propeller 31 further includes a propeller hub 311 and propeller blades 312 provided on the outer periphery of the propeller hub 311, and the propeller blades 312 are the components of the propeller 31 that generate thrust. Preferably, the rear part of the propeller hub 311 of the propeller 31 is provided with vortex elimination ribs 313, and the inclination direction of the vortex elimination ribs 313 is the same as the inclination direction of the propeller blades 312, and both are either left- or right-handed. More preferably, the rotation angle of the vortex elimination rib 313 is equal to or similar to the rotation angle of the propeller blades 312. In the present embodiment, the number of the vortex elimination ribs 313 is equal to the number of the propeller blades 312, and the vortex elimination ribs 313 and the propeller blades 312 are provided one to one in parallel with each other; the shape of the vortex elimination ribs 313 is equal to or similar to the shape of the propeller blades 312; the inclination angle of the vortex elimination ribs 313 is equal to or similar to the inclination angle of the propeller blades 312; the axial distance between the vortex elimination rib 313 and the propeller blade 312 is 1 / 3 to 1 times the blade radius of the vortex elimination rib 313; the area of the vortex elimination rib 313 is 1 / 2 to 1 / 5 of the area of the propeller blade 312. In the present embodiment, the area of the vortex elimination rib 313 is 1 / 4 of the area of the propeller blade 312.Small blades having a certain angle and shape (i.e., the vortex elimination rib 313) are attached to appropriate positions on the rear part of the propeller hub 311 (i.e., the hub cap) of the propeller 31. The vortex elimination rib 313 can straighten the wake of the propeller 31, whereby the surface water flow almost drains in a straight line along the rib and is dispersed rearward to the hub cap, whereby the hub vortex bladder is weakened, and since the hub vortex bladder is weakened, the pressure at the rear end of the propeller hub 311 is reduced, and the induced resistance caused by the hub vortex bladder is also reduced, whereby the feed efficiency of the propeller 31 is improved; In addition, the small blades of the vortex elimination ribs 313 generate torsion that reduces the torque of the propeller 31 and generates thrust, thereby increasing the thrust of the propeller 31, and at the same time, the vortex elimination ribs 313 can also effectively reduce the noise of the propeller 31 and the vibration amplitude of the propeller 31, thereby improving the stability of the water surface cleaning robot during operation. (As shown by relevant experimental data, boats on the water surface equipped with vortex elimination fins can achieve energy savings of about 2% to 5%).The number of the vortex elimination ribs 313 is equal to the number of the propeller blades 312 on the propeller 31, and the vortex elimination ribs 313 are provided in one-to-one correspondence with the propeller blades 312, that is, the axial position of the vortex elimination rib 313 is equal to that of the propeller blade 312 corresponding thereto. The fact that the axial position of the vortex elimination rib 313 is equal to that of the propeller blade 312 corresponding thereto may form a counterrotating vortex. The counter-rotating vortex may induce a surge (upwind) of the airflow within the vortex elimination ribs 313. According to the third Newton's law (action and reaction), the up-wash air flow inside the propeller 31 with the vortex elimination ribs 313 exerts a reaction force on the vortex elimination ribs 313 (and thus on the propeller 31), i.e. a downward pressure and a resistance. Such an arrangement enables the water surface cleaning robot to float better on the water surface and such downward pressure is also of some help in landing or stepping up steps.As shown in FIG. 7, in one embodiment, the propeller 31 further includes a flow guide cover 314 provided at the front part of the propeller 31 relative to the hub cap. It is understood that the front and rear parts herein are relative to the moving direction of the water surface cleaning robot as it moves forward. It should be noted that both the flow guide cover 314 and the hub cap have a streamline structure and their surface curvature is further determined by the placement space and size of the propeller blade 312. The flow guide cover 314 having a circular arc-shaped outer surface has a hydrodynamic structure, which allows the pool robot to improve the thrust weight ratio of the propeller 31 in the forward movement, thereby achieving an energy saving effect. The use of only one support frame to support the propeller 31 can not only effectively reduce the entanglement of hairs on the support frame, but also ensure drainage by the propeller 31 and reduce waste of kinetic energy.The drive mechanism 3 further comprises a mounting frame 32 for mounting the propeller 31, wherein the mounting frame 32 comprises a support frame having a plurality of support ribs 321 for supporting the propeller 31.As shown in FIGS. 5 and 7, in the present embodiment, the number of the driving mechanisms 3 is two, and the two driving mechanisms 3 are provided at intervals. When the two driving mechanisms 3 operate simultaneously, the engine moves forward; when one driving mechanism 3 operates or the rotational speeds of the two propellers 31 are not synchronized, steering of the engine can be achieved.In some embodiments, the controller may be directly connected to the power grid or a mobile power supply via a cable. And in order to allow the water surface cleaning robot to move more flexibly, in connection with FIG. 1, in one embodiment, a rechargeable battery 12 electrically connected to the controller is provided inside the main body 1, that is, the electric power for the driving mechanism 3 is provided by the rechargeable battery 12.In connection with Figs. 1, 5, 8 and 9, the garbage chamber 2 is provided with an inlet 21, through which garbage can enter the interior of the garbage chamber 2 with the water flow and thus be retained in the garbage chamber 2. The inlet 21 is provided on the side wall of the front part of the garbage chamber 2 in the vicinity of the main body 1. The garbage chamber 2 comprises a reset member, a frame 22, and a handle 23, wherein the handle 23 is rotatably connected to the frame 22, the reset member is in contact with the frame 22 and the handle 23, respectively, and the reset member is for moving the handle 23 from a first position to a second position. The second position refers to the handle 23 being in an upright or nearly upright state relative to the frame 22, thereby maintaining some distance between the handle position of the handle 23 and the frame 22, so that the user can grip the handle 23 with one hand, thereby reducing the possibility that the user's hand will contact the garbage. The reset member includes, but is not limited to, a torsion spring and a spring leaf. In the present embodiment, the reset member 8 is a torsion spring. Specifically, the handle 23 is provided with a shaft portion 231, and the handle 23 is rotatably connected to the frame 22 via the shaft portion 231, and the torsion spring is rolled on the shaft portion 231 to achieve the position limitation of the torsion spring.In conjunction with FIGS. 1 and 8, in the course of sliding the top cover 4 from the open position to the closed position, the top cover 4 contacts the handle 23 of the garbage chamber 2 located in the cavity 11 and gradually tilts the handle 23 downward. As shown in Figs. 8 and 9, the joint between the handle 23 and the frame 22 is located at the central portion of the top of the frame 22 to allow the frame 22 to maintain a state of equilibrium of forces when the user pulls out the garbage chamber 2. Preferably, one side of the top part of the frame 22 is provided with a receiving groove 221 to receive at least a portion of the handle 23, and the handle 23 can be at least partially received in the receiving groove 221 after being placed downward.Optionally, the frame 22 comprises a base body 222 and a flap 223, wherein the handle 23 is rotatably connected to the base body 222, the base body 222 has an opening, the flap 223 is arranged at the opening, the flap 223 is used for opening and closing the interior space of the base body 222, and one end of the flap 22 is rotatably connected to the base body 222, the other end of the flap 223 is provided with a first removable connection structure 2231, the base body 222 is provided with a second removable connection structure that cooperates with the first removable connection structure 2231, and the inlet 21 is located on a first side wall of the base body 222. The first removable connection structure 2231 and the second removable connection structure may be a snap fit, a magnetic attraction piece, or other structural shapes such as a latch structure. Preferably, the main body 222 as a whole has the shape of a polygonal frame, so that when the flap 223 is opened, the frame 22 can be fully opened, so that the garbage can more easily fall within the frame 22.Preferably, the opening of the base body 222 is at the lowermost part of the base body 222, whereby the user can be prevented from accidentally touching the garbage and the user experience can be improved; the second removable connection structure is at a second side wall of the base body 222, the first side wall being provided opposite the second side wall, so that the second side wall has sufficient space to accommodate the second removable connection structure. In other embodiments, it is also possible for the opening to be located on a side wall of the base body 222. In this case, the flap 223 can be considered as a side wall of the base body, that is to say the filter basket has a lateral opening structure.In some embodiments, one connection point between the handle 23 and the base body 222 is located on the first side wall and the other connection point is located on the second side wall; in the present embodiment, one connection point between the handle 23 and the base body 222 is located on a third side wall of the base body and the other connection point is located on a fourth side wall of the base body that is opposite the third side wall, the first side wall is connected to the third and fourth side walls, respectively, and the second side wall is connected to the third and fourth side walls, respectively.In conjunction with FIGS. 1, 5, 9, and 10, the water surface cleaning robot optionally further includes a rolling member 5, the rolling member 5 is provided on the main body 1, and the rolling member 5 is provided near the inlet 21 of the garbage chamber 2, and the rolling member 5 is used to carry garbage in the water into the garbage chamber 2. It will be appreciated that, as shown in Figure 11, in some specific products, the rolling element 5 may be provided on the waste barrel 2 and near the inlet 21 of the waste barrel 2.The inlet 21 is oriented in the direction of movement of the water surface cleaning robot. In the present embodiment, the inlet 21 and the drive mechanism 3 are separately provided at the both opposite ends of the main body 1. Specifically, the inlet 21 is provided at the front part of the garbage chamber 2, and the drive mechanism 3 is provided at the rear part of the main body 1. It should be additionally explained that inlets 21 can also be provided respectively at two opposite ends of the garbage chamber, so that when the drive mechanism 3 reverses and moves in the other direction, the garbage can still travel with the water flow through the inlet 21 into the interior of the garbage chamber 2, so that the water surface cleaning robot can collect floating objects both during forward and during rearward movement.As shown in FIG. 10, in order to improve the cleaning effect of the water surface cleaning robot, it is preferable to provide a drive assembly 8 for driving the rolling element 5 to rotate inside the main body 1, the drive assembly 8 including a rotation motor 81, etc., the drive assembly 8 being electrically connected to the controller, and the rechargeable battery 12 providing electric power to the drive assembly 8. It is to be noted that, when the rolling member 5 is rotatably provided on the garbage chamber 2 via a shaft member, the end of the shaft member is provided with a drive gear 82, and the drive gear 82 is located on the outside of the garbage chamber. Herein, the drive assembly 8 within the main body 1 drives the rolling element 5 for rotation via the drive wheel 82, wherein the drive wheel 82 includes, but is not limited to, a gear, a contact runner, etc.As shown in FIGS. 10 and 11, a leakage protection screen 24 is optionally provided on the waste chamber 2 in order to further prevent overflow of waste even within the waste chamber. When the leakage shield 24 is in a predetermined position, the leakage shield 24 closes at least a portion of the inlet 21.In one embodiment, one side of the leakage shield 24 is hinged to the inlet 21 via a shaft rod 25, and the shaft rod 25 can be driven to drive the leakage shield 24 to rotate about the axis of the shaft rod 25 to block the inlet 21, thereby achieving the effect of preventing the garbage within the garbage chamber 2 from overflowing from the inlet 21.The water surface cleaning robot having the leakage shielding screen 24 opens the leakage shielding screen 24 in the process of collecting floating objects, so that the floating objects enter the garbage chamber 2 under the shaking motion of the rolling member 5. At this time, it is difficult for the floating objects to overflow from the inlet 21 under the action of the water flow. When the collection stops, the leakage shield 24 is used to block the inlet 21 and prevent the floating objects from overflowing, so that the design size of the inlet 21 can be increased as much as possible to ensure the collection efficiency and at the same time prevent the floating objects from overflowing again.As shown in Figure 10, it will be appreciated that for specific products, the leakage shield 24 and the rolling element 5 may be driven either by the same drive assembly 8 or by different drive mechanisms. To simplify the structure, preferably, the leakage shield 24 and the rolling element 5 are driven by the same drive assembly 8, and specifically, the drive assembly 8 further includes a gear assembly drivingly connected to the rotation motor 81, and the gear assembly is drivingly connected to the rolling element 5 and the shaft rod 25, respectively, and as another improvement, the gear assembly only drives the leakage shield 24 to rotate in the direction in which the inlet 21 is blocked and causes the rolling element 5 to rotate in the same direction as the leakage shield 24.Further, a restricting portion 242 may be provided, and specifically, the restricting portion 242 may be provided on the main body 1 or may also be provided on the garbage chamber 2, and after the leakage prevention baffle 24 opens under the gravity, it abuts on the restricting portion 242 and assumes a state in which an end of the leakage baffle 24 remote from the inlet 21 is inclined downward. When the leakage shielding screen 24 abuts the limiting portion 242, the angle between the leakage shielding screen 24 and the horizontal plane is 15° to 40°. On the one hand, the resistance of the water surface cleaning robot during the movement can be reduced, and on the other hand, the floating objects can be guided to improve the collection efficiency.Practical process: The water surface cleaning robot is placed on the water surface and driven by the drive mechanism 3 to move in the first direction. At this time, the rotation motor 81 rotates in the forward direction, whereby the rolling element 5 rotates in the direction of water flow, i.e., counterclockwise. At this time, a one-way bearing 85 is in a slipping state, the leak prevention shutter 24 opens under gravity, and the rolling element 5 rotates counterclockwise to push the garbage into the garbage chamber; when the collection stops, the rotation motor 81 reverses the rotation direction, whereby the rolling element 5 rotates clockwise. At this time, the one-way bearing 85 is in a driving state, whereby the leakage prevention shutter 24 is driven to rotate to block the inlet 21.As shown in FIG. 11, in another embodiment, the leakage shield 24 may also be provided inside the garbage chamber 2 in the vicinity of the inlet 21, and the leakage shield 24 may freely rotate inside the garbage chamber 2 and may be rotated by 0 to 100 degrees relative to the direction of water flow (opposite direction to the traveling direction of the water surface cleaning robot). If the leakage protection screen 24 is at an angle of 80 to 100 degrees to the direction of the water flow, the leakage protection screen 24 is located above the water level line 9.In one embodiment, the position of the leakage shield 24 is arranged such that when the leakage shield 24 is at an angle of 90 degrees to the direction of water flow, the free end of the leakage shield 24 is 5 to 20 mm higher than the water level line 9, and that when during rotation of the leakage shield 24, its free end is closest to the brush blades of the rolling element 5, it is just not in contact with the brush blades of the rolling element 5.In order to simplify the structure of the garbage chamber 2, the leak shield 24 is reset to the closed position by its own buoyancy when the water surface cleaning robot stops its forward movement and floats on the water surface. In an alternative embodiment, the material density of at least a portion of the leakage shield 24 is less than the density of water having a density of 1 g / cm3. When the water surface cleaning robot advances, the water flow will push the leakage shield 24 to rotate, so that the leakage shield 24 is tilted rearward at a certain angle corresponding to the opening of the inlet 21, so that the garbage can enter more easily. When the water surface cleaning robot is stationary or moving backward, the leakage shield 24 is reset to the closed position under the action of the buoyancy or the water flow. At this time, the top end (i.e., the free end) of the leakage shield 24 protrudes beyond the water level 9, thereby preventing garbage from leaking out of the garbage chamber 2.In order to be able to reset the leakage protection screen 24 more quickly into the closed position, an air cavity is optionally provided on the leakage protection screen 24. It is readily understood that the material density of the leakage shield 24 at this time may not be less than the density of water. In other embodiments, a counterweight is provided on the leakage shield 24 in order to be able to reset the leakage shield 24 into the closed position more quickly. When the leakage shield 24 is in the closed position, the counterweight is below the rotational central axis of the leakage shield 24. the counterweight may be either an additional weight or a local area of the leakage shield 24 whose material density is greater than the density of water.In an embodiment, as shown in FIG. 11, the restricting portion 242 is a restricting protrusion provided on the frame 22. The range of the angles of rotation of the leakage protection screen 24 is limited by the limiting section 242. The range of the rotation angle of the leakage shield 24 is 0° to 100°, and when the leakage shield 24 is in a horizontal state, the rotation angle of the leakage shield 24 is 0°, and when the leakage shield 24 is in an upright state, the rotation angle of the leakage shield 24 is 90°. In the present embodiment, the entire top end of the leakage shield 24 protrudes beyond the water level line 9 when the leakage shield 24 is at 80° to 100°. That is, in the actual product, the closed position of the leakage shield 24 may not correspond to a unique and single numerical value of the rotation angle, but rather to a range of a group of rotation angles such as 80° to 100°.In conjunction with FIGS. 1 to 4, 8, 11 and 12, optionally, the water surface cleaning robot further includes a solar panel 6 provided on the surface of the top cover 4, wherein a solar controller is provided inside the main body 1, and the solar controller connects the rechargeable battery 12 to the solar panel 6. As a preferred embodiment, a first conductive pattern 42 electrically connected to the solar panel 6 is further provided on the top cover 4, and a second conductive pattern 14 electrically connected to the rechargeable battery 12 is provided on the main body 1. When the top cover 4 is in the closed position, the first conductive pattern 42 and the second conductive pattern 14 are electrically conductive, and when the top cover 4 is in the open position, the first conductive pattern 42 and the second conductive pattern 14 are held electrically conductive or have a disconnected line. The first conductive structure 42 is a metallic contact blade, a metallic spring blade, a metallic probe, or a first connector.In particular, when the upper cover 4 is in the open position and it is desired that the first conductive pattern 42 and the second conductive pattern 14 remain continuously conductive, a simple method is to form the first conductive pattern 42 as a metal contact sheet having a larger length, and the length direction of the metal contact sheet having a larger length coincides with the sliding direction of the upper cover 4.In other embodiments, the first conductive structure 42 and the second conductive structure 14 may also be optionally present non-metallic electrically conductive structures, such as electrically conductive structures such as magnetic attraction. In this way, the problem of susceptibility to corrosion of metallic conductive structures is avoided, which helps extend the life of the first conductive structure 42 and the second conductive structure 14 and improve the user experience.In conjunction with FIGS. 11 through 12, in one embodiment, the first conductive structure 42 is a wireless charge transmitting module and the second conductive structure 14 is a wireless charge receiving module. Specifically, a sealed chamber 20 is provided inside the main body 1, the wireless charge receiving module is provided inside the sealed chamber 20, and optionally, the rechargeable battery 12 is also provided inside the sealed chamber 20; a circuit board is provided inside the sealed chamber 20, and the wireless charge receiving module and the rechargeable battery 12 are each electrically connected to the circuit board.In manufacturing, after completion of the wiring of the wireless charging transmission module and the solar panel 6, the gap is sealed by pouring adhesive, that is, the wireless charging transmission module is sealed so that the wireless charging transmission module is not affected by moisture. Since the wireless charging transmission module is integrated with the top cover 4 and the solar panel 6, the wireless charging transmission module is stationary relative to the solar panel 6 regardless of how the top cover 4 is opened or closed. The wireless charge receiving module is installed inside the sealed chamber 20, and the sealed chamber 20 is waterproof, and the wireless charge receiving module can be installed therein. When the top cover 4 is closed, the positions of the wireless charge transmission module and the wireless charge reception module correspond to each other, and the wireless charging can be performed. When the top cover 4 is opened, the positions of the wireless charge sending module and the wireless charge receiving module are offset, and charging is stopped.Optionally, the sealed chamber 20 has a convex boss 201 protruding toward the top cover 4, and the wireless charge receiving module is at least partially inside the convex boss 201. The provision of the convex boss 201 not only enables convenient positioning and installation of the wireless charge receiving module, but also reduces the distance between the wireless charge transmitting module and the wireless charge receiving module at the respective positions, thereby improving the charging efficiency.The electric power generated from the solar panel 6 can be used by the drive mechanism 3, which contributes to reducing the power consumption of the water surface cleaning robot and reducing the use cost for the user. At the same time, the solar panel 6 and the drive mechanism 3 are electrically connected using a wireless connection path, which can not only improve the aesthetics of the water surface cleaning robot, but also reduce the risk of accidental suppression of the connection path between the solar panel 6 and the drive mechanism 3, which contributes to the improvement of the life of the water surface cleaning robot.Optionally, the top surface of the top cover 4 is provided with a mounting groove, and the solar panel 6 is mounted in the mounting groove. Preferably, the solar panel 6 is installed in the mounting groove at an inclination so that the liquid remaining on the solar panel 6 can be discharged without any problem to avoid interfering with the operation of the solar panel 6. It is easily understood that the solar panel 6 is installed inclined so as to form an acute angle between its top surface and the horizontal plane, thereby facilitating smooth emptying of the liquid adhering to the solar panel 6.In another embodiment, as shown in FIGS. 13 and 14, the electrical energy generated by the solar panel 6 is transmitted via a cable 45 to an electrical load component, such as the rechargeable battery 12, within the main body 1. Specifically, a cavity 44 for accommodating the cable 45 is provided inside the top cover 4, and when the top cover 4 is in the open position, the cable 45 is in an extended state inside the cavity 44, and when the top cover 4 is in the closed position, the cable 45 is accommodated inside the cavity 44. By connecting the solar panel 6 to the electric load components using a cable 45, the problems of electrolysis and corrosion of the conductive structure are solved, whereby the life of the conductive structure of the solar panel 6 can be effectively prolonged and the stability of the operation of the solar panel 6 can be secured.The shape of the cavity 44 is that of a long strip extending in the direction of movement of the top cover 4. Preferably, the cable 45 is a helical cable to enable the cable 45 to be received in an orderly fashion within the cavity 44. The helical cable may be expanded or compressed in an orderly fashion within the cavity 44.Furthermore, a winding column 46, a carrier plate 47 or other structures for carrying the spiral cable are provided within the cavity 44. The spiral wire may be placed around the winding column 46 or placed on the support plate due to gravity. At this point, the cable 45 may be better and more efficiently received within the cavity 44, thereby avoiding unreliable impact factors caused by an excessively long cable. Taking the example of providing the winding column 46, the elongated cable 45 can be withdrawn in order as the top cover 4 moves from the opened to the closed position due to the guiding action of the winding column 46, thereby gradually decreasing the helical pitch. The cooperation of the winding column 46 and the spiral cable can ensure that no cable clamping occurs during the sliding operation of the upper cover 4.It is understood that, when the support plate 47 is provided inside the cavity 44, an opening groove 471 is provided on the support plate 47 so that one end of the cable 45 can be passed through the opening groove 471 and connected to the electric load component in the main body 1, the longitudinal direction of the opening groove 471 coincides with the sliding direction of the top cover 4, and the length of the opening groove 471 is defined by the amount of displacement of the top cover 4. The support plate 47 having the opening groove 471 is simple in structure and easy to process and manufacture. In the specific production process, the support plate 47 may be either integrally injection molded with other portions of the top cover 4 or attached to the top cover 4 with fasteners, which is selected as needed.It should be noted that in this illustration, for the purpose of clearly illustrating the various embodiments, not only the winding column 46 is provided, but also the support plate 47 is provided. In the concrete embodiment, only the winding post 46 or only the support plate 47 may be provided on the upper cover 4, and in other embodiments, the winding post 46 and the support plate 47 may be provided together with the opening groove 471, which is selected depending on the actual need.If the support plate 47 is provided within the cavity 44, preferably if the cross-sectional dimension of the cavity 44 is only slightly larger than the total outer diameter of the cable 45 in the retracted state, the cable 45 itself does not overlap in the process of returning the cable 45 from the extended state to the retracted state, thereby ensuring that the extended cable 45 can be retracted in an orderly manner, thereby gradually decreasing the helical pitch.It should be noted that in particular products it is also possible that the rechargeable battery 12 is not provided in the product. In this case, the solar controller connects the solar panel 6 to the electric devices in the water surface cleaning robot such as the drive mechanism 3, the rotating motor 81, etc. That is, the electric devices in the water surface cleaning robot are directly powered by the solar panel 6 or by a power / mobile power supply with support of the solar panel 6 at this time.In conjunction with Figs. 5 and 15 to 20, the bottom surface of the main body 1 is provided with an anti-strand device 7 for preventing the water surface cleaning robot from strand during operation. Preferably, the number of anti-strand devices 7 is multiple. In the present embodiment, the number of the anti-strand devices 7 is two, and the two anti-strand devices 7 are provided near the left and right sides of the main body 1, respectively. In other embodiments, the number of the anti-strand devices 7 may be four or more, and when the number of the anti-strand devices 7 is four, two anti-strand devices 7 are provided at the two opposite ends of the main body 1, respectively.In some embodiments, the anti-strand device 7 may be a collision sensor, a distance measurement sensor, or another type of sensor. When the anti-strand device 7 is a collision sensor, the collision sensor transmits a collision signal to the controller that controls the engine to travel backward or turn. When the anti-run-on device 7 is a distance measurement sensor, the distance measurement sensor transmits information on the distance between the bottom surface of the main body 1 and the bottom below to the controller, and when this distance information is less than a predetermined threshold, the controller controls the machine to reverse or turn.In some other embodiments, the anti-strand device 7 may also be an interference structure of a non-electronic sensor type, and in this case, the anti-strand device 7 prevents the strain by directly interfering with structures such as steps in the working environment.The water surface cleaning robot in the present embodiment uses direct interference to achieve anti-strain. Specifically, the anti-strand device 7 is rotatably connected to the main body 1, and optionally, a damping structure is provided at the connection location between the anti-strand device 7 and the main body 1. Of course, it is also possible to provide a C-shaped holding spring in contact with the anti-strand device 7 at the joint between the anti-strand device 7 and the main body 1. By utilizing the elasticity of the C-shaped holding spring, the anti-strand device 7 can be held in the open / closed position, which contributes to the improvement of the working stability of the anti-strand device 7.Referring to FIGS. 15 to 18, in one embodiment, the main body 1 has mounting parts 17 provided opposite to each other, a shaft hole is provided on the mounting part 17, a rotation shaft 71 is provided on the shaft hole, the anti-strand device 7 is rotatably connected to the main body 1 via the rotation shaft 71, and a restricting member 72 for restricting axial sliding of the rotation shaft 71 is mounted on the rotation shaft 71. In mounting the anti-strand device 7, first, the rotation shaft 71 penetrates from the outside of one mounting part 17, and one end of the rotation shaft 71 passes through the anti-strand device 7 and the other mounting part 17 in sequence, and then the restricting member 72 is fixed to the rotation shaft 71. When the rotary shaft 71 moves axially, the restricting member 72 fixed to the rotary shaft 71 abuts against the anti-strand device 7 and / or the mounting part 17, thereby restricting the axial sliding of the rotary shaft 71. Optionally, the restriction member 72 has a bayonet, the rotation shaft 71 has a bayonet slot that fits the bayonet, and the restriction member 72 is snap-connected to the rotation shaft 71, thereby facilitating disassembly and assembly of the restriction member 72 and the rotation shaft 71. In the present embodiment, the restricting member 72 is concave and the restricting member 72 is provided with two bayonets. In this way, not only can the production consumables of the restriction member 72 be reduced, but the restriction member 72 can also be disassembled and assembled more easily by the user.Optionally, the anti-strand device 7 has a groove-shaped cross section. In some embodiments, the damping structure may be received in a groove of the anti-strand device 7. In the present embodiment, the restricting member 72 is accommodated in the groove of the anti-strand device 7.The water surface cleaning robot further includes a third limiting structure, the third limiting structure including a first limiting portion and a second limiting portion configured to cooperate with each other, and the first limiting portion is provided on the anti-strand device 7, and the second limiting portion is provided on the main body 1. The cooperation of the first restricting portion and the second restricting portion may allow the anti-strand device 7 and the main body 1 to maintain a relative positional relationship, thereby preventing unintentional movement of the anti-strand device 7 relative to the main body 1.Optionally, the first limiting portion includes a first stop surface 73 and a second stop surface 74 provided at an angle to each other, and the second limiting portion includes an elastic stop portion provided on the main body 1. In the present embodiment, the first stopper surface 73 and the second stopper surface 74 are arranged perpendicular to each other, and a rounded structure is provided at the joint between the two. In detail, the elastic stopper portion is an elastic arm 18 provided on the main body 1. In some embodiments, the elastic stopper portion may be an elastic washer provided on the main body 1, etc. The elastic washer includes, but is not limited to, a metal spring washer and a rubber washer. In other embodiments, the first boundary portion and the second boundary portion may also have other structural shapes, such as a concavo-convex matching structure.The lowermost part of the main body 1 is provided with a bearing groove 19 for supporting the anti-strand device 7. In the present embodiment, the mounting part 17 is the side wall of the bearing groove 19, and the elastic arm 18 is a portion of the bottom wall of the bearing groove 19.The anti-strand device 7 need not necessarily be rotatable relative to the main body 1 to allow retraction and extension. As shown in FIGS. 19 and 20, in other embodiments, it is also possible that the anti-strangulation device 7 is designed to be raised and lowered relative to the main body 1. When the anti-strand function of the water surface cleaning robot is turned on, the anti-strand device 7 descends and protrudes from the storage groove 19, and when the anti-strand function of the water surface cleaning robot is turned off, the anti-strand device 7 ascends and retracts into the storage groove 19.As an example of an raisable anti-strand device 7, the bearing groove 19 on the main body 1 is communicated with the outside on the bottom surface of the main body 1, preferably the bearing groove 19 is provided in the vertical direction and an elastic lock block 75 is provided on the anti-strand device 7, and on the surface of the wall of the main body 1 a plurality of lock holes 191 are provided for communicating with the bearing groove 19 and the lock holes 191 cooperate with the lock block 75. When the lock block 75 is engaged with the different lock holes 191, the anti-strand device 7 protrudes from the bottom surface of the main body 1 to different extents. Preferably, the same one bearing groove 19 is communicated with two of the locking holes 191. When the lock block 75 is inserted into one of the lock holes 191, the anti-strand device 7 is accommodated in the bearing groove 19. When the latch block 75 is inserted into the other of the latch holes 191, the lowermost end of the anti-strand device 7 protrudes relative to the bottom surface of the main body 1, thereby performing the anti-strand forming function. It is readily understood that in a specific operation, the user can press directly the latch block 75 that is locked into the latch bore 191, thereby unlocking the anti-strand device 7 such that the anti-strand device 7 can slide along the bearing groove 19 such that the latch block 75 locks into another latch bore 191.After the anti-strand device 7 is turned on, the anti-strand device 7 is triggered when the water surface cleaning robot hits a staircase or moves into shallower underwater areas, thereby transmitting a signal to the controller of the water surface cleaning robot, which controls the water surface cleaning robot to retract or turn to prevent the water surface cleaning robot from falling into the shallow water area.In summary, in the water surface cleaning robot provided by the present invention, the upper cover is slidably connected to the main body, and the opening and closing of the cavity is achieved by the structure of the slidable upper cover, which not only facilitates the removal of the garbage chamber but also minimizes the leverage at the connection between the upper cover and the main body, so that it is not liable to be accidentally damaged, which contributes to prolonging the life of the water surface cleaning robot; it is provided with an anti-strand device, which can effectively prevent a stratifying and contributes to ensuring a long-term stable operation of the water surface cleaning robot; The handle of the garbage chamber can automatically jump up when the top cover is slidably opened so that the user can easily take out the garbage chamber, and can also be automatically lowered with the top cover when the top cover is closed without the user having to manually operate the handle, which facilitates the operation by the user and contributes to improvement of the user experience; the garbage chamber opens from below, which is convenient for the user in cleaning.The foregoing is only embodiments of the invention and does not limit the scope of the invention.
