Description

Technical Field

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

[0002] To improve waste collection efficiency, a rotating brush is typically installed at the front of a water surface cleaning robot. During waste collection, the rotating brush primarily pushes the waste into a collection bin. Chinese utility model patent [Patent No. 202322785915.5] discloses a rotating brush for a water surface cleaning robot. This robot has a rotating brush mounted on its shell, with both ends connected to the shell. Inside the shell is a collection bin with a baffle on one side and an opening extending to the baffle at the top. The rotating brush is positioned above the baffle and includes several blades, each with a hook at one end facing the water-entry side. The brush is hinged to the robot shell via a snap-fit ​​connection to a mounting hole. A motor and a transmission gear are fixedly connected inside the countersunk hole, meshing with each other. The transmission gear is fixedly connected to the snap-fit ​​connection. Disassembling this brush is inconvenient; the motor must be disassembled first, and then the brush removed from the robot shell. Therefore, a roller brush mechanism that can be installed without disassembling the motor needs to be designed. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a self-locking roller brush mechanism for a water surface cleaning robot. This mechanism facilitates the installation and disassembly of the roller brush plate. By removing the positioning sleeve and then pulling out the spindle, the roller brush plate can be separated.

[0004] The purpose of this utility model can be achieved through the following technical solution: A self-locking roller brush mechanism for a water surface cleaning robot includes a frame, a drive assembly, roller brush plates, a spindle, and a positioning sleeve. The drive assembly is fixed on one side of the frame, and the other side of the frame has an installation cylinder. The positioning sleeve is embedded in the installation cylinder and fixed to the installation cylinder. Several roller brush plates are sleeved on the spindle and rotate synchronously with the spindle. One end of the spindle is poweredly connected to the drive assembly, and the other end of the spindle is rotatably connected to a bearing. The bearing is embedded in the inner end of the positioning sleeve, and the outer end of the positioning sleeve is connected to an end cap that can automatically lock onto the positioning sleeve.

[0005] Furthermore, a self-locking block is embedded inside the positioning sleeve, and the self-locking block has several elastic claws. The inner side of the end cap has a protruding head that can be held by the elastic claws.

[0006] Furthermore, the outer end of the positioning sleeve has a horizontally extended flange with a connecting hole on it, and the mounting sleeve has several threaded holes. After the connecting hole and the threaded hole are aligned, they are fastened by inserting bolts.

[0007] Furthermore, the flange has several bosses, each with a U-shaped groove. An elastic element is connected inside the U-shaped groove. The end cap has several pressing blocks corresponding to the positions of the bosses. After the end cap is connected to the positioning sleeve, the pressing blocks abut against the elastic element.

[0008] Furthermore, a pull ring is connected inside the positioning sleeve. After unscrewing the bolt, the pull ring can be grasped and pulled outwards to remove the positioning sleeve from the mounting cylinder.

[0009] Furthermore, the cross-section of the mandrel is a regular hexagon.

[0010] Furthermore, the drive assembly includes a motor and a drive shaft, with the motor being poweredly connected to the drive shaft, and the drive shaft having a hexagonal hole for inserting a spindle.

[0011] Furthermore, the roller brush plate has three parts, each with a central hole through which the mandrel passes. The three roller brush plates are arranged in a row and fitted onto the mandrel, rotating synchronously with the mandrel. After the mandrel is removed, the roller brush plates separate from each other, allowing for cleaning or replacement of the roller brush plates.

[0012] The roller brushes are fitted one by one onto the spindle. One end of the spindle engages with the drive shaft of the drive assembly, while the other end is rotatably connected to the positioning sleeve via a bearing. Starting the motor rotates the roller brushes, drawing debris from the front of the water surface cleaning robot into its interior for collection. For disassembly, first press the end cap inwards. The squeezing block compresses the elastic element, causing it to bend. Releasing the pressure causes the elastic element to rebound, pushing the squeezing block outwards and disengaging the protrusion from the elastic claw. At this point, the end cap disengages from the positioning sleeve. Unscrew the bolts and pull the ring to remove the positioning sleeve from the mounting cylinder. Then, pull the spindle out of the mounting cylinder, and the roller brushes will automatically detach, completing the disassembly.

[0013] Compared with existing technologies, the self-locking roller brush mechanism of this water surface cleaning robot has the following advantages:

[0014] 1. The spindle and brush plate adopt a separate structure. The brush plate can be removed from the frame by pulling the spindle out of the mounting cylinder on the other side of the drive assembly. There is no need to disassemble the motor of the drive assembly. The installation and disassembly are very quick and convenient.

[0015] 2. The end cap is self-locking. The protrusion can be inserted into the self-locking block to lock the positioning sleeve and the end cap. Pressing the end cap inward again will push it out by the rebound force of the elastic element. Attached Figure Description
