Description

Technical Field

[0001] The present invention belongs to the technical field of water surface cleaning equipment and relates to a water surface cleaning robot. Background Art

[0002] High-class hotels are basically equipped with public swimming pools. With the improvement of living standards, more and more private residences are also equipped with private swimming pools. The biggest difficulty with swimming pools lies in cleaning up garbage. Currently, there are few devices on the market for cleaning floating garbage on the water surface. Usually, manual salvage is used to fish out the garbage, which is time-consuming and laborious. Thus, water surface cleaning robots have emerged. For example, for the rotary brush of a water surface cleaning robot with the Chinese published patent number 202322785915.5, during the forward movement of the robot, the motor rotates to drive the engaged transmission gear to rotate. Since the transmission gear is fixedly connected to the clamping portion, it will drive the rotary brush to rotate together. Since the rotary brush is arranged above the baffle and at the opening of the storage basket, the blades on the rotary brush will shovel the garbage passed by the robot into the storage basket from the opening of the storage basket. Due to the blocking effect of the baffle, the garbage collected in the storage basket will not fall out of the storage basket again, achieving the function of cleaning the water surface garbage. Since the rotary brush is of an integral structure, the clamping portions at both ends of the rotary brush are inserted into the mounting holes of the housing and are hinged, enabling the rotary brush to rotate on the robot housing. Then, the motor drives the transmission gear to rotate, and the transmission gear is fixedly connected to the clamping portion, achieving the purpose of driving the rotary brush to rotate by the motor. Since the rotary brush will entangle with sundries during rotation and needs to be disassembled in time for cleaning, but it is very inconvenient to disassemble the rotary brush with the above structure. First, the motor needs to be disassembled, the transmission gear needs to be separated, and then the rotary brush needs to be translated towards the motor side to disengage the clamping portion on the other side from the mounting hole before the rotary brush can be removed. Therefore, it is necessary to redesign the mounting structure of the rotary brush. Summary of the Invention

[0003] The purpose of the present invention is to address the above problems existing in the prior art and propose a water surface cleaning robot, which is equipped with a locking and separating component for the rotary brush mechanism, enabling the rotary brush plate to be quickly disassembled from the frame without disassembling the driving component.

[0004] The purpose of the present invention can be achieved by the following technical solutions: A water surface cleaning robot includes a frame, a storage mechanism, a rotary brush mechanism, and a traveling mechanism. It is characterized in that a through groove penetrating from front to back is provided on the frame. The rotary brush mechanism is arranged at the front end of the through groove, the storage mechanism is arranged in the middle of the through groove, and the traveling mechanism is arranged at the tail of the through groove; The storage mechanism includes a storage basket body that slides back and forth along the through groove, and a switch component that can lock and unlock the position of the storage basket body and the frame. The storage basket body has two side plates and a front baffle with a hollow interior. The upper cover of the storage basket body is rotatably connected, and the switch component is arranged inside the front baffle; The roller brush mechanism includes a driving assembly, a roller brush plate, a core shaft, a positioning sleeve and an end cover. The driving assembly is fixed on one side of the frame, and a mounting sleeve is provided on the other side of the frame. The positioning sleeve is embedded in the mounting sleeve and fixed to the mounting sleeve. Several roller brush plates are sleeved on the core shaft and rotate synchronously with the core shaft. One end of the core shaft is dynamically connected to the driving assembly, and the other end of the core shaft is rotationally connected to the inner end of the positioning sleeve through a bearing. A locking assembly is provided between the outer end of the positioning sleeve and the end cover, which can quickly connect and separate the two.

[0005] The traveling mechanism drives the entire water surface cleaning robot to move forward on the water surface and collects garbage floating on the water surface. The roller brush mechanism actively pushes leaves, branches and other debris into the through groove. Finally, the garbage is concentrated in the storage basket of the storage mechanism. The storage basket is pulled out from the through groove, and after cleaning the garbage inside, it is inserted back for continued use.

[0006] Furthermore, the frame has a limit baffle located in the through groove and capable of preventing the storage basket from continuing to slide backward. The groove wall of the through groove is provided with a track groove 1 and a track groove 2. The outer sides of the two side panels are provided with a slider and a sliding shaft. The slider can be embedded in the track groove 1 and slide along the track groove 1. The sliding shaft can be embedded in the track groove 2 and slide along the track groove 2. A positioning groove 1 is provided on the track groove 1. The lower end of the slider has a positioning point that is inserted into the positioning groove 1. A positioning groove 2 is provided on the track groove 2. When the positioning point is inserted into the positioning groove 1, the sliding shaft just falls into the positioning groove 2.

[0007] The storage basket slides along the groove wall of the through groove. When the storage basket slides to a position against the limit baffle, the positioning point is inserted into the first positioning groove, and the sliding shaft is inserted into the second positioning groove, thereby realizing the preliminary positioning of the storage basket.

[0008] Furthermore, the switch assembly includes a knob rotatably connected to the front baffle and two movable pins, a lock hole for the movable pin to be inserted is opened on the groove wall, movable holes for the outer ends of the movable pin to pass through are opened on both sides of the front baffle, the inner end of the movable pin is eccentrically hinged to the knob and the movable pin can be inserted into the lock hole by rotating the knob, an unlocking groove and a locking groove are opened on the side of the knob, and a convex strip that is inserted into the unlocking groove or the locking groove is provided in the front baffle.

[0009] By turning the knob, the movable pin can be extended out of the front baffle or retracted into the front baffle. When the outer end of the movable pin is inserted into the lock hole, the storage basket and the rack are completely locked and no longer slide relative to each other. The convex strip is used to position the knob to prevent the knob from rotating at will.

[0010] Further, as another solution, the switch assembly includes a pressing plate, a protective outer cover, and two movable pin shafts. Lock holes for inserting the movable pin shafts are formed on the groove wall. The two movable pin shafts are on the same straight line. The installation groove communicates with the front baffle and has a limiting seat. The inner end of the movable pin shaft has a stop block. A first spring is connected between the two stop blocks. The stop blocks abut against the limiting seat under the action of the first spring. The protective outer cover is fixed in the installation groove. A number of horizontally arranged guide posts are provided on the inner side of the protective outer cover. The pressing plate is sleeved on the guide posts and moves back and forth. The back of the pressing plate has a pressing part that penetrates through the protective outer cover. An inclined strip-shaped sliding hole is formed on the movable pin shaft. Vertical shafts inserted into the strip-shaped sliding holes are provided on both sides of the pressing plate. The outer end of the movable pin shaft can be inserted into the lock hole after passing through the front baffle.

[0011] Press the pressing part of the pressing plate forward by hand to move the pressing plate forward along the guide posts. Since the vertical shafts cooperate with the strip-shaped sliding holes, it drives the movable pin shafts to retract into the front baffle. The stop blocks of the movable pin shafts compress the first spring, causing the first spring to shorten. At this time, the storage basket can be taken out. When the hand is released, the first spring pushes the two movable pin shafts to move outward respectively, so that the outer ends of the movable pin shafts are inserted into the lock holes, realizing the locking of the storage basket and the frame. At the same time, the pressing plate also returns to its original position.

[0012] Further, the driving assembly includes a storage motor, an outer housing, a sealing cover, a worm, and a driving shaft. The storage motor is clamped in the outer housing. The worm and the driving shaft are both rotatably connected to the outer housing through bearings. The output shaft of the storage motor is connected to the worm and rotates synchronously. A worm gear meshing with the worm is fixed on the driving shaft. The driving shaft is connected to the core shaft and rotates synchronously. The sealing cover is buckled on the outer housing.

[0013] The driving assembly is used to drive the core shaft and the brush plate to rotate. The storage motor drives the worm to rotate. The worm drives the driving shaft to rotate through the worm gear. The driving shaft is linked with the core shaft.

[0014] Further, the locking and unlocking assembly includes a clamping outer tube fixed in the positioning sleeve, a clamping inner tube protruding from the inner wall of the end cover, and an unlocking block. The clamping inner tube can be inserted into the clamping outer tube. The unlocking block is rotatably connected to the end cover. A U-shaped elastic sheet is clamped in the clamping inner tube. The U-shaped elastic sheet has a protruding stud head. Through holes for the stud head to pass through are formed on the peripheral walls of the clamping outer tube and the clamping inner tube. The unlocking block has a top post facing the stud head. When the unlocking block swings, the top post can squeeze the stud head to make it contract into the clamping inner tube.

[0015] Further, a square hole is formed on the end cover. The unlocking block is located in the square hole. The unlocking block is L-shaped. A second spring is provided at the bottom of the square hole. The outer end of the second spring abuts against the unlocking block. The outer end of the positioning sleeve has a horizontally extended retaining edge. A connection hole is formed on the retaining edge. A number of threaded holes are formed on the mounting cylinder. After the connection hole and the threaded hole are aligned, they are fastened by inserting bolts. A pull ring is connected in the positioning sleeve.

[0016] First, install the U-shaped spring piece into the clamping inner tube so that the stud penetrates through the through hole of the clamping inner tube. When installing the end cap, insert the clamping inner tube into the clamping outer tube. The ends of the stud and the ejector pin are hemispherical, so the stud can be squeezed and sink by the clamping outer tube. When the through hole of the clamping outer tube is aligned with the through hole of the clamping inner tube, the stud is pushed up by the U-shaped spring piece to lock the clamping inner tube and the clamping outer tube, realizing the installation of the end cap and the positioning sleeve. When it is necessary to disassemble the end cap, press the unlocking block so that the ejector pin squeezes the stud back into the clamping inner tube. At this time, the clamping inner tube can be directly pulled out to separate the end cap from the positioning sleeve.

[0017] Furthermore, the cross-section of the mandrel is a regular hexagon. A hexagonal hole for the mandrel to insert is opened on the drive shaft, and a central hole for the mandrel to pass through is opened on the brush roller plate. Protective covers are clamped at both ends of the brush roller plate. A clamping groove for clamping with the brush roller plate is opened on the inner side of the protective cover. The protective cover near one end of the drive assembly abuts against the groove wall, and the other protective cover abuts against the positioning sleeve. A support washer that closely adheres to the inner wall of the protective cover is sleeved on the mandrel. The protective cover is used to protect the mandrel and can prevent the mandrel from contacting sundries and affecting the normal rotation of the mandrel.

[0018] Press the unlocking block to make the ejector pin push the stud back into the through hole of the clamping inner tube. At this time, pull the end cap outwards, and the end cap can be separated from the positioning sleeve. Then remove the bolt and pull out the positioning sleeve from the installation cylinder. Since the mandrel is rotatably connected to the positioning sleeve through a bearing, when pulling out the positioning sleeve, the mandrel and the brush roller plate can be pulled out together. The other end of the mandrel is only inserted into the hexagonal hole of the drive shaft, which is convenient for pulling out.

[0019] Furthermore, the traveling mechanism includes a drive motor and an impeller. The drive motor is fixed on the frame, and the impeller is fixed on the output shaft of the drive motor.

[0020] Compared with the prior art, the present surface cleaning robot has the following advantages: 1. A locking and separating component is provided, so that the positioning sleeve can be directly pulled out at the installation cylinder end without disassembling the drive component end, and the mandrel and the brush roller plate can be pulled out together. Therefore, the installation and disassembly of the brush roller mechanism are very fast and convenient.

[0021] 2. A switch component is provided, which can quickly unlock or lock the storage basket to prevent the storage basket from shifting.

[0022] 3. The protective cover can prevent sundries such as ropes, fabrics or branches and leaves from winding around the mandrel during rotation, resulting in rotation obstruction or direct jamming.

[0023] 4. The brush roller is of a split type, and the mandrel can be horizontally pulled out from the brush roller plate, which is convenient for disassembly, assembly and cleaning. Description of the Drawings

[0043] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0044] Embodiment 1 like Figures 1-3 As shown, the water surface cleaning robot includes a frame 1, a storage mechanism 2, a roller brush mechanism 3 and a travel mechanism 4. The frame 1 is provided with a through groove 11 which passes through the front and back. The roller brush mechanism 3 is arranged at the front end of the through groove 11, the storage mechanism 2 is arranged in the middle of the through groove 11, and the travel mechanism 4 is arranged at the tail of the through groove 11; the travel mechanism 4 includes a driving motor 41 and an impeller 42, the driving motor 41 is fixed on the frame 1, and the impeller 42 is fixed on the output shaft of the driving motor 41.

[0045] The traveling mechanism 4 drives the entire water surface cleaning robot to move forward on the water surface and collects garbage floating on the water surface. The roller brush mechanism 3 actively pushes leaves, branches and other debris into the through groove 11. Finally, the garbage is concentrated in the storage basket 21 of the storage mechanism 2. The storage basket 21 is pulled out from the through groove 11, and after cleaning the garbage inside, it is inserted back for continued use.

[0046] As Figures 4-6 shown, the storage mechanism 2 includes a storage basket 21 that slides back and forth along the through groove 11, and a switch assembly 5 that can lock and unlock the position of the storage basket 21 and the frame 1. The storage basket 21 has two side plates 22 and a front baffle 23 with a hollow interior. The upper end of the storage basket 21 is rotatably connected to an upper cover 24, and the switch assembly 5 is arranged inside the front baffle 23.

[0047] On the frame 1, there is a limit baffle 13 located in the through groove 11 and capable of preventing the storage basket 21 from sliding backward continuously. On the groove wall of the through groove 11, there are a first track groove 14 and a second track groove 15. On the outer sides of the two side plates 22, there are sliding blocks 25 and sliding shafts 26. The sliding blocks 25 can be embedded in the first track groove 14 and slide along the first track groove 14, and the sliding shafts 26 can be embedded in the second track groove 15 and slide along the second track groove 15. A first positioning groove 16 is formed on the first track groove 14, and the lower end of the sliding block 25 has a positioning point 27 that can be snapped into the first positioning groove 16. A second positioning groove 17 is formed on the second track groove 15. When the positioning point 27 is snapped into the first positioning groove 16, the sliding shaft 26 just falls into the second positioning groove 17.

[0048] The storage basket 21 slides along the groove wall of the through groove 11. After the storage basket 21 slides to a position where it abuts against the limit baffle 13, the positioning point 27 is snapped into the first positioning groove 16, and the sliding shaft 26 is snapped into the second positioning groove 17, realizing the preliminary positioning of the storage basket 21.

[0049] As Figure 7 shown, the switch assembly 5 includes a knob 51 rotatably connected to the front baffle 23 and two movable pin shafts 52. On the groove wall, there are lock holes 18 for inserting the movable pin shafts 52. On both sides of the front baffle 23, there are movable holes 28 for the outer ends of the movable pin shafts 52 to pass through. The inner ends of the movable pin shafts 52 are eccentrically hinged to the knob 51, and rotating the knob 51 can insert the movable pin shafts 52 into the lock holes 18. An unlocking groove 53 and a locking groove 54 are formed on the side surface of the knob 51, and a convex strip 29 that can be snapped into the unlocking groove 53 or the locking groove 54 is arranged inside the front baffle 23.

[0050] By rotating the knob 51, the movable pin shafts 52 can be extended out of the front baffle 23 or retracted into the front baffle 23. When the outer ends of the movable pin shafts 52 are inserted into the lock holes 18, the storage basket 21 and the frame 1 are completely locked and no longer slide relative to each other. The convex strip 29 is used to position the knob 51 and prevent the knob 51 from rotating randomly.

[0051] As Figures 12-14As shown in the figure, the rotary brush mechanism 3 includes a drive assembly 6, a rotary brush plate 31, a mandrel 32, a positioning sleeve 33 and an end cap 34. The drive assembly 6 is fixed to one side of the frame 1, and there is an installation cylinder 12 on the other side of the frame 1. The positioning sleeve 33 is embedded in the installation cylinder 12 and fixed to the installation cylinder 12. A plurality of rotary brush plates 31 are sleeved on the mandrel 32 and rotate synchronously with the mandrel 32. One end of the mandrel 32 is power-connected to the drive assembly 6, and the other end of the mandrel 32 is rotationally connected to the inner end of the positioning sleeve 33 through a bearing. A locking and separating assembly 7 capable of quickly connecting and separating the positioning sleeve 33 and the end cap 34 is provided between the outer end of the positioning sleeve 33 and the end cap 34.

[0052] As Figures 14-16 shown in the figure, the locking and separating assembly 7 includes a clamping outer tube 71 fixed inside the positioning sleeve 33, a clamping inner tube 72 protruding from the inner wall of the end cap 34, and an unlocking block 73. The clamping inner tube 72 can be inserted into the clamping outer tube 71. The unlocking block 73 is rotatably connected to the end cap 34. A U-shaped elastic piece 74 is clamped inside the clamping inner tube 72. The U-shaped elastic piece 74 has a protruding stud head 75. Through holes 76 for the stud head 75 to pass through are opened on the peripheral walls of both the clamping outer tube 71 and the clamping inner tube 72. The unlocking block 73 has a top column 77 facing the stud head 75. When the unlocking block 73 swings, the top column 77 can squeeze the stud head 75 to make it contract into the clamping inner tube 72.

[0053] A square hole is opened on the end cap 34. The unlocking block 73 is located in the square hole. The unlocking block 73 is L-shaped. A second spring 78 is provided at the bottom of the square hole. The outer end of the second spring 78 abuts against the unlocking block 73. The outer end of the positioning sleeve 33 has a horizontally extended retaining edge 35. A connection hole 36 is opened on the retaining edge 35. A plurality of threaded holes 19 are opened on the installation cylinder 12. After the connection hole 36 is aligned with the threaded holes 19, they are fastened by inserting bolts. A pull ring 37 is connected inside the positioning sleeve 33.

[0054] First, install the U-shaped elastic piece 74 into the clamping inner tube 72 so that the stud head 75 passes through the through hole 76 of the clamping inner tube 72. When installing the end cap 34, insert the clamping inner tube 72 into the clamping outer tube 71. The ends of the stud head 75 and the top column 77 are hemispherical, so the stud head 75 can be squeezed and sunk by the clamping outer tube 71. When the through hole 76 of the clamping outer tube 71 is aligned with the through hole 76 of the clamping inner tube 72, the stud head 75 is pushed up by the U-shaped elastic piece 74 to lock the clamping inner tube 72 and the clamping outer tube 71, realizing the installation of the end cap 34 and the positioning sleeve 33. When it is necessary to disassemble the end cap 34, press the unlocking block 73 to make the top column 77 squeeze the stud head 75 back into the clamping inner tube 72. At this time, the clamping inner tube 72 can be directly pulled out to realize the separation of the end cap 34 and the positioning sleeve 33. After removing the bolts, hold the pull ring 37 and pull it outwards to facilitate pulling out the positioning sleeve 33 from the installation cylinder 12.

[0055] The cross-section of the mandrel 32 is a regular hexagon. A hexagonal hole 67 for inserting the mandrel 32 is formed on the drive shaft 65. A central hole for the mandrel 32 to pass through is formed on the brush roller plate 31. Protective covers 38 are clamped at both ends of the brush roller plate 31. A clamping groove for clamping with the brush roller plate 31 is formed on the inner side of the protective cover 38. The protective cover 38 near one end of the drive assembly 6 abuts against the groove wall, and the protective cover 38 at the other end abuts against the positioning sleeve 33. A support washer 39 that closely adheres to the inner wall of the protective cover 38 is sleeved on the mandrel 32. The protective cover 38 is used to protect the mandrel 32 and can prevent the mandrel 32 from contacting sundries and affecting the normal rotation of the mandrel 32.

[0056] Press the unlocking block 73 to make the ejector pin 77 push the stud head 75 back into the through hole 76 of the clamping inner tube 72. At this time, pull the end cover 34 outwards, and the end cover 34 can be separated from the positioning sleeve 33. Then remove the bolt and pull out the positioning sleeve 33 from the mounting cylinder 12. Since the mandrel 32 is rotationally connected to the positioning sleeve 33 through a bearing, the mandrel 32 can be withdrawn while pulling out the positioning sleeve 33. One end of the mandrel 32 is only inserted into the hexagonal hole 67 of the drive shaft 65, and the brush roller plate 31 can be easily removed.

[0057] As Figures 17-18 As shown, the drive assembly 6 includes a receiving motor 61, an outer housing 62, a sealing cover 63, a worm 64, and a drive shaft 65. The receiving motor 61 is clamped in the outer housing 62. The worm 64 and the drive shaft 65 are both rotationally connected to the outer housing 62 through bearings. The output shaft of the receiving motor 61 is connected to the worm 64 and rotates synchronously. A worm gear 66 meshing with the worm 64 is fixed on the drive shaft 65. The mandrel 32 is inserted into and rotates synchronously with the hexagonal hole 67 of the drive shaft 65. The sealing cover 63 is buckled on the outer housing 62. The drive assembly 6 is used to drive the mandrel 32 and the brush roller plate 31 to rotate. The receiving motor 61 drives the worm 64 to rotate, the worm 64 drives the drive shaft 65 to rotate through the worm gear 66, and the drive shaft 65 is linked with the mandrel 32.

[0058] As Figure 14 As shown, since some sundries may occasionally be wound on the brush roller plate 31, it needs to be disassembled in time, cleaned, and then reinstalled. The inner end of the positioning sleeve 33 holds the bearing in place through a limit screw 79. During disassembly, when the positioning sleeve 33 is pulled out, the mandrel 32 and the brush roller plate 31 are pulled out of the mounting cylinder 12 together.

[0059] Embodiment Two As Figures 8-11As shown, the difference from the first embodiment lies in the different structure of the switch assembly 5. The switch assembly 5 of this embodiment includes a pressing plate 55, a protective outer cover 56, and two movable pin shafts 52. Lock holes 18 for inserting the movable pin shafts 52 are formed in the groove wall. The two movable pin shafts 52 are on the same straight line. The installation groove communicates with the front baffle 23 and has a limit seat 57. The inner end of the movable pin shaft 52 has a stopper 58. A first spring 59 is connected between the two stoppers 58. The stopper 58 abuts against the limit seat 57 under the action of the first spring 59. The protective outer cover 56 is fixed in the installation groove. A number of horizontally arranged guide posts 510 are provided inside the protective outer cover 56. The pressing plate 55 is sleeved on the guide posts 510 and moves back and forth. The back of the pressing plate 55 has a pressing portion 511 that penetrates the protective outer cover 56. An inclined strip-shaped sliding hole 512 is formed in the movable pin shaft 52. Vertical shafts 513 inserted into the strip-shaped sliding hole 512 are provided on both sides of the pressing plate 55. After the outer end of the movable pin shaft 52 penetrates the front baffle 23, it can be inserted into the lock hole 18.

[0060] Press the pressing portion 511 of the pressing plate 55 forward by hand to make the pressing plate 55 move forward along the guide posts 510. Due to the cooperation of the vertical shaft 513 and the strip-shaped sliding hole 512, the movable pin shaft 52 is driven to retract into the front baffle 23. The stopper 58 of the movable pin shaft 52 presses the first spring 59, causing the first spring 59 to shorten. At this time, the storage basket 21 can be taken out. When the hand is released, the first spring 59 pushes the two movable pin shafts 52 to move outward respectively, so that the outer ends of the movable pin shafts 52 are inserted into the lock holes 18, realizing the locking of the storage basket 21 and the frame 1.
