Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine shaft processing equipment, and in particular relates to a heat treatment and cleaning equipment for wind turbine shafts. Background Technology

[0002] Wind turbine shafts refer to shaft-like components in wind turbine generator sets used for transmitting torque and supporting the structure; they are one of the core components of wind power equipment.

[0003] After heat treatment, the wind turbine shaft is placed in a cleaning tank for quenching and cleaning. Impurities on its surface fall off into the tank. After long-term use, the waste residue accumulated at the bottom of the tank needs to be shoveled up manually. Since shoveling up the waste residue at the bottom of the tank requires draining the liquid in the tank, and the waste residue also needs to be sent upwards when shoveling it out, the operation of cleaning waste residue using conventional wind turbine shaft heat treatment and cleaning equipment is quite troublesome.

[0004] Therefore, we propose a heat treatment and cleaning equipment for wind turbine shafts to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the operation of cleaning waste residue in conventional wind turbine shaft heat treatment and cleaning equipment is relatively troublesome, and to propose a wind turbine shaft heat treatment and cleaning equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cleaning device for heat treatment of wind turbine shafts includes a cleaning tank. The cleaning tank contains a filter screen, and a valve plate is slidably mounted on the side of the filter screen. A spring clip is fixedly connected to the upper part of the filter screen, and the spring clip engages with the valve plate. Residue that falls off during cleaning falls into the filter screen. When the residue accumulates too thickly inside the filter screen, an external hoisting device is used to lift the filter screen, and the residue is removed through the filter screen. Then, the valve plate is pulled upwards to sweep out the residue from the filter screen, and the filter screen is placed back into the cleaning tank for easy cleaning of the residue at the bottom of the tank.

[0007] Preferably, the filter screen includes a screen frame, a guide groove is provided on the side of the screen frame, and a baffle is fixedly connected to the lower end of the screen frame. The guide groove is used to guide the valve plate to slide, the baffle is used to catch the waste residue, the valve plate is opened, and the waste residue accumulated on the baffle is swept out, making it convenient to remove the waste residue.

[0008] Preferably, a lifting ring is fixedly connected to the upper end of the mesh frame. A rope is passed through the lifting ring, and the rope is lifted using hoisting equipment. The filter screen is then lifted using the rope, facilitating the lifting of the filter screen with the aid of hoisting equipment.

[0009] Preferably, the valve plate includes a plate body, and a snap-fit ​​groove is formed on the side of the plate body. A spring-loaded snap fastener is used to fasten the plate body into the snap-fit ​​groove, maintaining its height and facilitating its suspension after being pulled up, thus ensuring the valve plate remains in its unfolded state.

[0010] Preferably, the valve plate further includes a handle, which is fixedly connected to the upper end of the plate body. Pulling the handle upwards opens the plate body by applying upward pressure on it, while pressing the handle downwards opens the shielding mesh frame of the plate body, facilitating the opening or closing of the valve plate.

[0011] Preferably, the spring clip includes a spring piece, and a locking block is fixedly connected to the upper end of the spring piece. The elastic force of the spring piece acts on the locking block, and the locking block acts on the locking groove, increasing the resistance to the downward movement of the valve plate and facilitating the stabilization of the valve plate's height.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. After washing, the residue falls into the filter screen. When the residue accumulates too thickly in the filter screen, use external hoisting equipment to lift the filter screen, use the filter screen to remove the residue, then pull the valve plate upward to sweep out the residue in the filter screen, and then put the filter screen back into the cleaning tank to facilitate cleaning the residue at the bottom of the tank.

[0013] 2. The guide groove is used to guide the sliding of the valve plate. The waste residue is picked up by the baffle. When the valve plate is opened, the waste residue accumulated on the baffle is swept out, making it easy to remove the waste residue.

[0014] 3. Use the spring clips to fasten the valve plate in the slots to keep the plate at a certain height, making it easy to lift the valve plate and hold it in place, thus keeping the valve plate in the unfolded state.

[0015] 4. Hold the handle and pull it upwards. The upward force of the handle on the plate will open the plate. Press the handle downwards and the handle will open the shielding mesh frame of the plate, making it easy to open or close the valve plate. Attached Figure Description
