Description
Technical Field
[0001] This utility model relates to the field of quick-release brush head technology, and in particular to a quick-release connection device for the brush head of a tracked photovoltaic cleaning robot. Background Technology
[0002] The tracked photovoltaic cleaning robot is an automated cleaning device designed specifically for large-scale photovoltaic power plants. Its core structure revolves around two main functions: tracked movement and efficient cleaning. The robot's main body uses a high-strength aluminum alloy frame and is equipped with a dual-track drive system. The track surface is covered with high-friction rubber material to adapt to power plant scenarios with different installation angles. The cleaning mechanism is equipped with two sets of rotating brushes and a high-pressure spray device. The brushes are made of soft nylon material, which can remove dust and bird droppings from the panel surface without scratching the glass coating. The spray system can be connected to a water source or equipped with a small water tank, supporting the alternating use of clean water rinsing and environmentally friendly cleaning agents to meet the cleaning needs of different levels of pollution. In order to quickly disassemble the brush head, a quick-release connection device for the brush head of the tracked photovoltaic cleaning robot is required.
[0003] Currently available quick-release connection devices for the brush heads of tracked photovoltaic cleaning robots mainly consist of a brush head interface assembly, a drive unit, and a connection device. They are suitable for daily maintenance scenarios in photovoltaic power plants. When the brush head is worn, contaminated with stubborn stains, or needs to be replaced with a brush head of a different material to adapt to various photovoltaic panels, operators can quickly disassemble and assemble it without tools by pressing the unlock button. This reduces downtime and improves equipment maintenance efficiency in complex outdoor environments. However, cleaning fluid or sand can easily seep into the connection gaps, leading to corrosion of internal components and affecting the lifespan of the transmission coupler. To solve these problems, existing technologies only embed nitrile rubber rings at the interface between the connection base and the brush head, combined with a labyrinthine sealing groove to form a double waterproof and dustproof barrier. The interface edge is designed with oblique drainage grooves to reduce liquid residue. However, the quick-locking and fixing structure of the brush head has not been improved, resulting in an unstable lock. The brush head may radially shift during high-speed rotation, colliding with the robot body or the photovoltaic panel frame, causing brush head breakage, drive motor overload, or even damage to the photovoltaic panel surface, thus failing to meet usage requirements. Summary of the Invention
[0004] To overcome the above deficiencies, this utility model provides a quick-release connection device for the brush head of a tracked photovoltaic cleaning robot. It aims to improve the existing technology, which does not improve the quick-locking and fixing structure of the brush head, resulting in poor locking. The brush head will radially deviate during high-speed rotation, collide with the robot body or the photovoltaic panel frame, causing the brush head to break, the drive motor to be overloaded, or even the surface of the photovoltaic panel to be damaged.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-release connection device for the brush head of a tracked photovoltaic cleaning robot, comprising a mounting column, a connecting plate fixedly connected to the bottom end of the mounting column, a brush block fixedly connected to the bottom end of the connecting plate, a fixing mechanism provided inside the connecting plate for fixing the cleaning device, a positioning mechanism provided at the top end of the brush block for assisting installation, the fixing mechanism comprising a motor, the outer wall of the motor fixedly connected to the inside of the connecting plate, a drive shaft fixedly connected to the output end of the motor, a pushing component provided at the bottom end of the outer wall of the drive shaft, and a fixing component provided on the side of the pushing component that is furthest away from it.
[0006] As a further description of the above technical solution: The positioning mechanism includes a limiting rod, the bottom end of which is fixedly connected to the top end of the brush block. Two limiting holes are opened on both the front and rear sides of the connecting plate. A locking component is provided on the outer wall of the connecting plate. An elastic component is provided on the top end of the limiting rod. A pushing block is fixedly connected to the bottom end of the elastic component. A limiting component is provided on the bottom end of the pushing block.
[0007] As a further description of the above technical solution: The pushing assembly includes a gear, the middle of which is fixedly connected to the bottom of the outer wall of the drive shaft, and racks are meshed on both the front and rear sides of the outer wall of the gear.
[0008] As a further description of the above technical solution: The fixing component includes an insert block, the adjacent side of which is fixedly connected to the opposite side of the rack, and the brush block has a slot inside.
[0009] As a further description of the above technical solution: The engaging assembly includes a locking block, which is located on the left and right sides of the connecting disc, and the locking block has a locking groove inside.
[0010] As a further description of the above technical solution: The elastic component includes a guide rod, the top end of which is fixedly connected to the inner bottom end of the limiting rod, and a spring is fixedly connected to the outer wall of the guide rod.
[0011] As a further description of the above technical solution: The limiting component includes a rotating shaft, the left and right sides of the outer wall of the rotating shaft are fixedly connected to the inside of the limiting rod, and a limiting lever is rotatably connected to the middle of the outer wall of the rotating shaft.
[0012] As a further description of the above technical solution: The bottom of each brush block is fixedly connected with multiple bristles, and the top center of each brush block has an installation groove.
[0013] This utility model has the following beneficial effects: 1. In this utility model, the connecting plate is inserted into the mounting groove opened in the middle of the top of the brush block. The motor is started to output power to drive the drive shaft to rotate. The rotation of the drive shaft drives the gear to rotate. The rotation of the gear drives the rack to move. The movement of the rack drives the moving top to be inserted into the interior of the brush block, thereby achieving quick positioning and improving the efficiency of brush head replacement.
[0014] 2. In this utility model, the limiting hole opened on the connecting plate engages with the outer wall of the limiting rod, and at the same time, the slot engages with the inner wall of the card block to achieve precise positioning and avoid the fixing mechanism being unusable after insertion. After insertion, the spring force pushes the pushing block to slide down and pushes the limiting card rod to rotate on the outer wall of the rotating shaft, engaging with the top of the connecting plate, thereby achieving rapid positioning and pre-fixing at the same time.
