Description

Technical Field

[0001] This invention belongs to the field of maintenance technology for hydro-generator sets, specifically a cleaning tool for the main shaft of a hydro-generator set. Background Technology

[0002] During the operation of a hydro-generator unit, its main shaft is prone to accumulating oil stains and requires regular cleaning. There are currently two methods for cleaning the main shaft: Method 1: Use a long bamboo pole with a broom tied to it, and wrap a rag around the broom to wipe the main shaft; Method 2: Set up a telescopic ladder and use a rag to wipe the main shaft.

[0003] All of the above solutions have certain problems. Solution 1: The main shaft is too high, and the long bamboo pole is too long, making it easy for the pole to bend and unable to apply force. The broom side cannot be in close contact with the main shaft for cleaning, and stubborn oil stains cannot be removed. The main shaft is also too high to spray oil stain cleaner; it can only be sprayed onto a rag to clean the main shaft, resulting in a low concentration of cleaning solution and poor cleaning effect. Solution 2: The main shaft is too high and cylindrical. The fit between the telescopic ladder and the main shaft is poor, posing a risk of the telescopic ladder tipping over and people falling from a height. Summary of the Invention

[0004] The present invention aims to address the technical deficiencies of the prior art by providing a cleaning tool for the main shaft of a hydro-generator unit, thereby solving the technical problems of inconvenient operation, poor cleaning effect, and safety risks associated with conventional cleaning methods for the main shaft of hydro-generator units.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] A cleaning tool for the main shaft of a hydro-generator set includes a telescopic rod, a telescopic rod fixing device, a universal joint, an arc panel, an electromagnet, Velcro, cloth clips, a wire, a battery, a wire retractor, a spray pipe bracket, a spray pipe, a spray bottle, and a spray pipe retractor. The telescopic rod is divided into several sections, with fixing devices between adjacent telescopic rods. A universal joint is located at the front end of the telescopic rod, and an arc panel is connected to the universal joint. An electromagnet and Velcro are located on the front side of the arc panel, and cloth clips are located at the left and right ends of the rear side of the arc panel. One end of the wire is connected to the electromagnet, and the other end is connected to the battery. A wire retractor is located along the extension path of the wire. A spray pipe bracket is fixedly connected to the arc panel, with the front end of the spray pipe fixed to the spray pipe bracket and the rear end of the spray pipe connected to the spray bottle. A liquid pump is located on the spray pipe or the spray bottle, and the liquid pump is electrically connected to the battery. A spray pipe retractor is located along the extension path of the spray pipe.

[0007] In the above technical solution, two cloth clips secure the mop from both sides, while the Velcro on the front of the curved panel adheres to the mop, ensuring its stability on the front of the curved panel. The electromagnet on the front of the curved panel attracts and secures the main shaft, and its curved shape allows for a good fit with the side surface of the main shaft, guaranteeing effective cleaning. Based on the above structure of the curved panel and its components, a multi-functional mop panel is formed.

[0008] Preferably, an electromagnet mounting box is fixedly connected to the rear side of the curved panel, the rear part of the electromagnet is fixedly installed in the electromagnet mounting box, and the wire passes through the electromagnet mounting box and is connected to the electromagnet.

[0009] Preferably, several fixing brackets are provided on the telescopic pole, and the wires and spray pipes are respectively fixed on the fixing brackets.

[0010] Preferably, an integrated control panel is fixedly connected to the rear end of the telescopic pole, and the battery and spray bottle are respectively fixedly installed on the integrated control panel.

[0011] Preferably, the integrated operation panel is equipped with an electromagnet suction force adjustment knob and an electric spray button. The electromagnet suction force adjustment knob is electrically connected to an electric wire, and the electric spray button is electrically connected to the power supply circuit of the liquid pump.

[0012] The integrated control panel not only houses the battery and spray bottle, but also includes control units such as the electromagnet suction adjustment knob and the electric spray button, thus forming a multi-functional integrated control panel.

[0013] Preferably, the wire retractor includes a turntable rotatably connected to a telescopic rod. The turntable's shaft is connected to a motor, which is electrically connected to a battery. The wire passes through the turntable, and the portion of the wire passing through the turntable is on the same plane as the turntable. Based on this structure, the turntable can wind the wire when it rotates, thereby achieving automated operation of the wire retractor.

[0014] Preferably, the spray nozzle retractor includes a turntable rotatably connected to a telescopic rod. The turntable's shaft is connected to a motor, which is electrically connected to a battery. The spray nozzle passes through the turntable, and the portion of the spray nozzle passing through the turntable is on the same plane as the turntable. Based on this structure, when the turntable rotates, it can wind the spray nozzle, thereby achieving automated operation of the spray nozzle retractor.

[0015] As a preferred option, the telescopic pole is divided into three sections and is made of aluminum alloy.

[0016] Preferably, there are two electromagnets and three Velcro straps, with the three Velcro straps and two electromagnets arranged horizontally at intervals on the front side of the curved panel.

[0017] Preferably, the battery is a 24V rechargeable lithium battery; the spray bottle has a capacity of 500mL.

[0018] In this invention, Velcro, also known as nylon fastener, is a product that is fastened by adhering a sheet with a napped surface and a sheet with a barbed surface. Velcro is a conventional product in the art and is commercially available. In this invention, the barbed sheet of the Velcro is preferred to facilitate adhesion to the fibrous side of the cloth.

[0019] This invention provides a cleaning tool for the main shaft of a hydro-generator set. This tool mainly includes a telescopic pole, a multi-functional mop panel, a multi-functional integrated control panel, an automatic wire retractor, and an automatic nozzle retractor.

[0020] During operation, first cover the multi-functional mop panel with a rag, and use Velcro and cloth clips to fix the rag to the mop panel. Then, use the three-section telescopic rod to raise the mop panel to the main shaft that needs to be wiped. First, turn on the electric spray nozzle to spray a high-concentration cleaning agent on the stains on the main shaft. Then, push the multi-functional mop panel to the stains, turn the electromagnet suction adjustment knob to increase the magnetic attraction, and stick the mop panel with the rag onto the turbine main shaft. The magnetic attraction replaces the radial thrust of the person, making up for the lack of radial force after the rod is extended, and thus cleaning stubborn stains at high places.

[0021] This tool kit integrates cleaning agent spraying and shaft cleaning, allowing one person to complete the shaft cleaning task.

[0022] The pipeline adopts a telescopic structure, which can meet the needs of working scenarios at a certain height. At the same time, the connecting rod can be retracted after the work is completed, which helps to reduce storage space and facilitates the placement and storage of tools and equipment.

[0023] The beneficial effects of this invention include:

[0024] 1) Using electromagnet attraction to apply pressure to the rag instead of manual labor ensures the effective removal of stubborn stains, avoids the safety risks of workers climbing to heights (which requires at least 4 people to complete), and reduces labor costs.

[0025] 2) The spray nozzle is sent to a high place by using a telescopic pole to spray the cleaning agent for stubborn stains, avoiding the safety risks of workers climbing to a height (climbing to a height requires at least 4 people to complete), and reducing labor costs.

[0026] 3) Use both Velcro and fabric clips to secure the cloth, avoiding the risk of the cloth falling off due to insecure fastening.

[0027] 4) A structure combining a telescopic pole with an automatic retractor and a fixed bracket was designed to avoid the risk of the wires and spray pipes getting tangled and knotted when the telescopic pole is extended or shortened.

[0028] 5) The multi-functional mop panel is made of aluminum alloy. Because aluminum alloy has a certain degree of elasticity, the curvature of the panel can be changed within a small range when subjected to pressure to adapt to the curvature of the side of the large shaft. Panels with different curvatures can also be selected according to different large shaft diameters to achieve cleaning work for large shafts of different diameters. Attached Figure Description
