Description

Technical Field

[0001] This utility model belongs to the technical field of water surface cleaning equipment, and relates to a water surface cleaning robot with a roller brush. Background Technology

[0002] A water surface cleaning robot is a cleaning device that automatically collects floating debris on the water surface. A through-channel is installed beneath the robot, extending from the front to the rear. The drive motor and impeller are located at the rear of the through-channel. The drive motor drives the impeller, propelling the robot forward. As the robot moves, water is drawn in from the front and discharged from the rear. A collection basket is located within the through-channel. The basket intercepts debris in the water flow and stores it inside. However, some debris, such as twigs and leaves, is harder and cannot be drawn into the through-channel by water alone, becoming stuck at the entrance and causing blockage. Therefore, a structure is needed to actively push the debris into the collection basket to improve collection capacity and prevent blockage. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a water surface cleaning robot with a roller brush. The roller brush is driven by a drive mechanism to rotate, forcefully rolling the garbage into the through-channel, thereby improving garbage collection efficiency.

[0004] The objective of this utility model can be achieved through the following technical solution: A water surface cleaning robot with a roller brush includes a frame and a roller brush rotatably connected to the frame. A drive mechanism for driving the roller brush to rotate is fixed on the outside of the frame. The drive mechanism includes a housing motor, an outer shell, a sealing cover, a worm gear, and a drive shaft. The housing motor is embedded in the outer shell. The worm gear and the drive shaft are both rotatably connected to the outer shell through bearings. The output shaft of the housing motor is connected to the worm gear and rotates synchronously. A worm wheel that meshes with the worm gear is fixed on the drive shaft. The drive shaft is connected to the roller brush and rotates synchronously. The sealing cover is fastened to the outer shell.

[0005] Furthermore, the roller brush includes a rotating shaft with a regular hexagonal cross-section, a bushing, and several actuating plates. The actuating plates are circumferentially fixed on the bushing. The bushing has a regular hexagonal hole for the rotating shaft to pass through, and the drive shaft has a regular hexagonal groove for the end of the rotating shaft to be embedded.

[0006] Furthermore, the frame has a through groove, the roller brush is rotatably connected to the front end of the through groove, a storage basket is embedded in the through groove, a travel motor is fixed at the tail end of the through groove, an impeller is fixed on the output shaft of the travel motor, and the roller brush is positioned higher than the storage basket.

[0007] Furthermore, the front end of the frame has outwardly inclined water guide plates, which are located on both sides of the front end of the through groove.

[0008] Furthermore, the outer casing is fixed to the sealing cover by bolts, and the sealing cover is fixed to the side of the frame by bolts.

[0009] Furthermore, a positioning block is fixed to the side of the motor, and a positioning groove is opened on the outer casing for the positioning block to be inserted.

[0010] The propulsion motor drives the impeller to rotate, propelling the entire water surface cleaning robot forward on the water surface. The negative pressure generated by the impeller causes water to flow through the through-channel. The debris at the front of the through-channel is carried by the water flow into the collection tank. The collection motor drives the roller brush to rotate. Some large or long pieces of debris are easy to get stuck at the port of the through-channel. The continuously rotating actuating plate on the roller brush will force the debris into the through-channel and store it in the collection tank. The water flows out from the filter holes of the collection tank.

[0011] Compared with existing technologies, this water surface cleaning robot with a roller brush has the following advantages:

[0012] 1. The rotation of the roller brush can forcefully push the garbage that is not easy to collect into the collection basket, making it easier to collect garbage and improving garbage collection efficiency.

[0013] 2. The rotating brush plate also continuously pushes water as it rotates, accelerating the water flow so that debris can enter the collection basket more quickly and the trash can stick more firmly to the inside of the collection basket. Attached Figure Description

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-3 As shown, this water surface cleaning robot with a roller brush includes a frame 1 and a roller brush 2 rotatably connected to the frame 1. A drive mechanism 3 for driving the roller brush 2 to rotate is fixed on the outside of the frame 1. The frame 1 has a through groove, and the roller brush 2 is rotatably connected to the front end of the through groove. A storage basket 4 is embedded in the through groove. A travel motor 5 is fixed to the rear end of the through groove, and an impeller 6 is fixed on the output shaft of the travel motor 5. The roller brush 2 is positioned higher than the storage basket 4. The front end of the frame 1 has outwardly inclined water guide plates 7, which are located on both sides of the front end of the through groove.

[0022] like Figure 4 As shown, the drive mechanism 3 includes a housing motor 31, an outer casing 32, a sealing cover 33, a worm gear 34, and a drive shaft 35. The housing motor 31 is embedded in the outer casing 32. The worm gear 34 and the drive shaft 35 are rotatably connected to the outer casing 32 through bearings 36. The output shaft of the housing motor 31 is connected to the worm gear 34 and rotates synchronously. A worm wheel 37 that meshes with the worm gear 34 is fixed on the drive shaft 35. The drive shaft 35 is connected to the roller brush 2 and rotates synchronously. The sealing cover 33 covers the outer casing 32.

[0023] The outer casing 32 is fixed to the sealing cover 33 by bolts, and the sealing cover 33 is fixed to the side of the frame 1 by bolts. A positioning block 39 is fixed to the side of the motor 31, and a positioning groove is opened on the outer casing 32 for the positioning block 39 to be inserted.

[0024] like Figure 5 As shown, the roller brush 2 includes a rotating shaft 21 with a regular hexagonal cross section, a bushing 22, and several actuating plates 23. The actuating plates 23 are circumferentially fixed on the bushing 22. The bushing 22 has a regular hexagonal hole for the rotating shaft 21 to pass through, and the drive shaft 35 has a regular hexagonal groove 38 for the end of the rotating shaft 21 to be embedded.

[0025] Work process: The propulsion motor 5 drives the impeller 6 to rotate, propelling the entire water surface cleaning robot forward on the water surface. The negative pressure generated by the impeller 6 causes water to flow through the through channel. The garbage at the front end of the through channel is carried by the water flow into the collection tank. The collection motor 31 drives the roller brush 2 to rotate. Some large or long garbage may get stuck at the port of the through channel. The actuating plate 23 on the roller brush 2 rotates continuously, which will force the garbage into the through channel and keep it in the collection tank. The water flows out from the filter hole of the collection tank.
