Description

Technical Field

[0001] This utility model relates to the field of equipment maintenance technology, specifically to a blade descaling nozzle mechanism. Background Technology

[0002] During operation, industrial blades can accumulate scale due to impurities in the medium, leading to decreased aerodynamic performance, increased vibration, and in severe cases, equipment failure. Traditional cleaning methods need to strike a balance between "ensuring no damage to the blades" and "thoroughly removing scale," and must be adapted to the cleaning requirements of different blade curvatures and scale types.

[0003] Traditional fixed nozzles mostly use direct or single-angle spraying, which can only cover the front of the blades and cannot thoroughly clean the back, edges, roots and other dead corners of the blades. Residual scale requires secondary cleaning. Traditional control relies on manual inspection and judgment, which results in a long delay from the discovery of scale to the start of cleaning response. During this period, the scale may further deteriorate. In addition, the clamping structure of the nozzle is mostly made of ordinary carbon steel, which is prone to rusting and deformation in high temperature and dusty environments. After a period of use, the bracket may loosen, causing the nozzle movement trajectory to deviate, reducing cleaning accuracy and requiring frequent maintenance. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a blade descaling nozzle mechanism to solve the problems of incomplete cleaning coverage and poor installation adaptability mentioned in the background art.

[0005] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution: This utility model provides a blade descaling nozzle mechanism, comprising: The mobile frame is a hollow frame that can accommodate blades to be cleaned to enter the internal working area from the side; the top of the mobile frame is provided with a vertical through connection hole. The nozzle assembly is used to spray the descaling agent onto the blades to be cleaned; Liquid supply assembly for storing and delivering descaling agent; A fluid delivery assembly, with one end connected to the liquid supply assembly and the other end connected to the nozzle assembly, is used to deliver the descaling agent to the nozzle assembly. The clamping and lifting assembly is installed on the movable frame and connected to the nozzle assembly at the bottom, so that the nozzle assembly passes through the connection hole and is used to support and drive the nozzle assembly to move up and down.

[0006] The technical effects achieved by the above setup are as follows: This mechanism is highly adaptable, and the movable frame can be flexibly fixed. During operation, the operator places the blades to be cleaned into the movable frame, and then the clamping and lifting components move the nozzle assembly downwards to a preset height, thus accommodating blades of different sizes and models, improving installation adaptability. Simultaneously, the movable frame can move along the blade direction, thereby solving the problem of incomplete cleaning coverage. After the position is adjusted, the descaling agent in the water tank is delivered to the nozzle assembly through the fluid delivery component, thereby achieving cleaning. Furthermore, the structure is streamlined, the core components are easily connected, and subsequent maintenance is convenient.

[0007] Furthermore, the movable frame is provided with fixing grooves for fixing the blades on both sides perpendicular to the blade entry direction; The fixing groove is C-shaped and is fixedly connected to the bottom of the top plate of the movable frame.

The angle adjustment shaft can be adapted to different blades, improving the adaptability of the device.

[0015] The angle adjustment axis can be directly selected from existing mature electric rotary adjustment turntables.

[0016] Furthermore, a guide plate covering both sides of the nozzle core is provided below the top plate of the movable frame; the guide plate is connected to the bottom of the top plate of the movable frame via a connecting block.

[0017] The above setup achieves the following technical effects: the connecting block at the bottom of the mobile frame provides a stable installation base for the guide plate, ensuring that the guide plate is fixed in position; the guide plate can guide the waste liquid or splashed descaling agent generated during the cleaning process, preventing it from spreading randomly and polluting the equipment or environment. At the same time, the overall structure is simple, does not add extra complexity to the mechanism, and is easy to adapt to existing mobile frames.

[0018] Furthermore, the fluid delivery assembly includes a distributor, a fixed pipe fixed in the connection hole, and a metal rigid pipe and a high-pressure hose, each respectively connecting the distributor and the nozzle core; The top of the fixed tube is connected to the metal rigid tube via a connecting pipe, and the bottom is sealed to the angle adjustment shaft via a sealing ring.

At the same time, the simplified connection structure also facilitates later maintenance.

[0021] Furthermore, the inlet of the diverter is connected to the liquid supply assembly via a water supply pipe, and the outlet of the diverter is connected to the metal rigid pipe and the high-pressure hose, respectively. A one-way valve is installed on the water supply pipe.

[0025] Furthermore, the liquid supply assembly includes a water tank and a water pump. The water tank is used to store the descaling agent, and the inlet of the water pump is connected to the water tank, while the outlet is connected to the fluid delivery assembly.

[0026] Furthermore, the nozzle mechanism also includes: A power supply component is installed on the movable frame and is electrically connected to the clamping and lifting component, the nozzle component and the liquid supply component, for providing power and controlling the coordinated operation of each component.

[0046] Based on the same technical concept as Embodiment 1, this embodiment provides a blade descaling nozzle mechanism, including the following components: The mobile frame assembly includes a mobile frame 1 made of 304 stainless steel, which provides structural support and mobility for the entire device. A C-shaped fixing groove 2 is provided on one side of the mobile frame 1 for placing the blades to be cleaned. A vertically adjustable pressure rod 3 is mounted on the top of the fixing groove 2, and a rubber wheel 4 is attached to the bottom of the pressure rod 3. By pressing down the pressure rod 3, the rubber wheel 4 can flexibly press the blades into the fixing groove 2. A connection hole 5 is also provided on the top of the mobile frame 1.

[0047] A clamping and lifting assembly is mounted on a movable frame. Specifically, this assembly includes a support frame 21 fixed to the movable frame 1. A support plate 27 is horizontally connected to the top of the support frame 21. An electric telescopic rod 23 is mounted at the bottom center of the support plate 27. A clamping ring 22 is fixedly mounted at the bottom of the piston rod of the telescopic rod 23. The clamping ring 22 serves as the mounting platform for the entire nozzle assembly, and the telescopic movement of the telescopic rod 23 drives the clamping ring 22 and all components on it to rise and fall as a whole.

[0048] The nozzle assembly is mounted on the clamping ring 22. Specifically, the assembly includes a nozzle housing 6, the top of which is connected to the clamping ring 22 via an angle adjustment shaft 8. The angle adjustment shaft 8 contains a motor and a transmission mechanism (such as a turntable), which can perform precise angle deflection under electrical signal control. A nozzle core 7 is mounted at the bottom of the nozzle housing 6. The nozzle core 7 is made of an abrasion-resistant material such as silicon nitride ceramic.

[0049] A fluid delivery assembly for delivering descaling agent. Specifically, the assembly includes a distributor 12 with two outlets, one connected to a rigid metal tube 11 and the other to a high-pressure hose 10. The other end of the rigid metal tube 11 is connected to a fixed tube 25, which is fixedly installed in a connection hole 5, via a connecting pipe 19. The bottom of the fixed tube 25 is dynamically sealed to the top inlet of the angle adjustment shaft 8 via a sealing ring 9. The other end of the high-pressure hose 10 is directly connected to the nozzle core 7. The inlet of the distributor 12 is connected to the liquid supply and power assembly via a water supply pipe 26, on which a one-way valve 13 is connected in series to prevent backflow of liquid.

The PLC control board 24 acts as the control center, connecting to the aforementioned electrical components via circuitry, and controlling the automated operation of the entire mechanism according to the preset program of the existing software, including blade clamping, nozzle lifting and angle adjustment, and cleaning start and stop.

[0052] Preferably, the power bank 18, water pump 17, angle adjustment shaft 8, telescopic rod 23, and pressure rod 3 are all existing electric products.

[0053] In this embodiment, the specific components include: The mobile frame 1, serving as the basic framework of the entire device, has connection holes 5 at its top, a support frame 21, a mobile power supply 18, and a PLC control board 24 mounted thereon; a connecting block 14 is mounted at its bottom; and a fixing groove 2 is provided on one side. As the core load-bearing structure, it provides the mounting foundation, structural support, and stability for all other components, and enables the overall movement of the mechanism.

[0054] The fixing slot 2, a C-shaped open slot structure, provides a channel for inserting and removing blades. It is located on one side of the moving frame 1, and the pressure rod 3 is fixedly connected to its top. It serves as a positioning and installation station for the blades, and cooperates with the pressure rod 3 and the rubber wheel 4 to reliably fix the blades to the device.

[0055] The pressure rod 3, a rod-shaped structure, can be electrically driven. Its top is vertically fixed to the top of the fixing groove 2, and its bottom is fixedly connected to a rubber wheel 4.

It is located at the top of the movable frame 1 and is internally fixedly connected to the fixing tube 25, while also providing a moving channel for the nozzle core 7. It serves two purposes: firstly, as a static mounting point for the fixing tube 25; and secondly, as a dynamic channel, allowing the nozzle core 7 to pass through it to approach or move away from the blades below when the entire nozzle assembly is raised or lowered.

[0058] The nozzle housing 6 is a hollow shell structure with internal flow channels (when the metal rigid tube 11, connecting pipe 19, and fixed tube 25 move, some liquid overflows and can be transported to the nozzle core 7 through the internal flow channels), used to accommodate and protect the nozzle core 7 and other internal components. An angle adjustment shaft 8 is fixedly connected to the top, and the nozzle core 7 is fixedly connected to the bottom; the entire housing is mounted on the clamping ring 22 via the angle adjustment shaft 8 and other components.

The top is sealed and movable to the fixed tube 25 via a sealing ring 9, and the bottom is fixedly connected to the nozzle housing 6. Its external structure (such as the motor and housing) is mounted on the clamping ring 22. While moving as a whole with the clamping ring 22, it independently drives the nozzle housing 6 and the nozzle core 7 to rotate at multiple angles to precisely align different parts of the blade.

[0061] The sealing ring 9 is fitted at the connection between the bottom of the fixed tube 25 and the top of the angle adjustment shaft 8, the connection between the nozzle housing 6 and the top of the angle adjustment shaft 8, and the connection between the bottom of the angle adjustment shaft 8 and the nozzle core 7, and is pressed between the two parts. It forms a dynamic seal between the fixed tube 25 and the movable angle adjustment shaft 8 to prevent the descaling agent from leaking out.

[0062] The high-pressure hose 10 is a flexible, bendable conduit, typically constructed of multiple layers of rubber / plastic and reinforcing layers (such as steel wire braid), and is resistant to high pressure. The top is fixed to the distributor 12 via connecting pipe 19 and metal rigid pipe 11, while the bottom is fixed to the nozzle core 7. The hose body is mounted on the clamping ring 22 along with the nozzle assembly. This forms a flexible fluid delivery path, ensuring that the descaling agent is smoothly and unimpededly delivered to the nozzle core 7 even when the nozzle moves and its angle changes.

[0063] The rigid metal pipe 11 is an inflexible, rigid pipe, typically made of stainless steel or copper. It is fixedly connected to the top of the diverter 12 and the bottom is fixedly connected to the pipe 19. It forms a rigid fluid transport path and is connected in parallel with the high-pressure hose 10 to divert and stabilize the system pressure, ensuring stable flow.

[0064] The diverter 12 is a multi-port cavity structure with internal flow channels that divides one inlet into two outlets. It is fixedly connected to the water supply pipe 26 at the top and to the metal rigid pipe 11 and high-pressure hose 10 at the bottom; its body is mounted on the clamping ring 22 or a support structure. It diverts the descaling agent from the water supply pipe 26 to two parallel paths, the metal rigid pipe 11 and the high-pressure hose 10, balancing the flow and pressure of the two paths.

[0065] The guide plate 15, a plate-like structure with a certain curvature or tilt angle, guides the flow of liquid. It is fixedly connected to one side of the working area below the top plate of the movable frame 1, located at the bottom of the device, below or to the side of the fixed tank 2. It receives and guides waste liquid and descaling agent splashed or dripped during the cleaning process, directing them to designated collection points to prevent contamination of the working environment.

[0066] Water tank 16 is fixedly connected to the inlet of water pump 17 via a pipe. It stores descaling agent to provide a continuous liquid supply for the cleaning system.

[0067] The water pump 17 is fixedly connected to the water tank 16 on its inlet side and to the water supply pipe 26 on its outlet side; it is also usually connected to the PLC control board 24 via wiring. It provides power to the entire cleaning system, drawing the descaling agent from the water tank 16 and pumping it into the delivery pipeline at a certain pressure and flow rate.

[0068] The portable power supply 18 is fixedly installed on the top of the mobile frame 1 and on one side of the support frame 21; it is electrically connected to the PLC control board 24 and water pump 17 and other electrical equipment via cables. It provides independent portable power to the control system and actuators of the entire device (such as PLC control board 24, water pump 17, and angle adjustment motor), eliminating the need for external power cords.

[0069] Connecting pipe 19 is a semi-rigid pipe. Its top is fixedly connected to a rigid metal pipe 11, and its bottom is fixedly connected to a fixed pipe 25. The connection between the rigid metal pipe 11 and the fixed pipe 25 forms part of a rigid fluid passage from the distributor 12 to the angle adjustment shaft 8.

[0070] The limiting ring 20 is fixedly connected to one side of the portion of the water supply pipe 26 that extends into the distributor 12. It mechanically limits the insertion depth of the water supply pipe 26 within the distributor 12, preventing it from being over-inserted or dislodged, and ensuring a stable assembly relationship.

[0071] The support frame 21 is a vertical support structure, with its bottom fixedly connected to the top of the mobile frame 1 and its top fixedly connected to the support plate 27. A mobile power supply 18 is fixedly installed on one side of the support frame 21. It provides stable vertical support for the support plate 27 and the mobile power supply 18, and transfers the weight and load of the relevant components to the mobile frame 1.

[0072] The clamping ring 22, a ring-shaped frame structure, serves as a small installation platform. The top is fixedly connected to the bottom of the telescopic rod 23, and the entire nozzle assembly, consisting of the nozzle housing 6, the angle adjustment shaft housing 8, the high-pressure hose 10, and the metal rigid pipe 11, is mounted on its ring body. It acts as the integrated mounting base and load-bearing frame for the entire movable nozzle assembly, transmitting the linear movement of the telescopic rod 23 to all nozzle components.

[0073] The telescopic rod 23, a linear drive mechanism, can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, and consists of an outer sleeve and a telescopic inner rod. It is fixedly connected to the bottom of the support plate 27 at the top and to the clamping ring 22 at the bottom; its drive motor is electrically connected to the PLC control board 24. Through its own extension and retraction, it precisely drives the clamping ring 22 and the entire nozzle assembly to rise and fall, thereby adjusting the working distance between the nozzle and the blades.

[0074] The PLC control board 24 is fixedly installed on the top of the mobile frame 1 and is electrically connected to the mobile power supply 18, water pump 17, motor of angle adjustment shaft 8, telescopic rod 23 and other actuators via cables.

[0075] The fixed pipe 25 is a rigid pipe fitting with a fixed connection to the connecting pipe 19 at the top and a sealed connection to the angle adjustment shaft 8 at the bottom via a sealing ring 9; its body is fixed inside the connection hole 5. It serves as a fixed fluid channel from the connecting pipe 19 to the angle adjustment shaft 8 and transmits the load of the upper pipeline to the movable frame 1 through the connection hole 5.

[0076] Water pipe 26, the main water supply pipe, is usually a flexible or rigid pipe with a certain diameter. One end is fixedly connected to the outlet of water pump 17, and the other end is fixedly connected to the inlet of distributor 12. One-way valve 13 is installed in series on its pipeline. It delivers the high-pressure descaling agent output by water pump 17 to distributor 12 and is the main liquid supply pipeline of the system.

[0077] The support plate 27 is fixedly connected to the top of the support frame 21 and the bottom is fixedly connected to the top of the telescopic rod 23. It provides a stable and horizontal mounting surface for the telescopic rod 23 and evenly transmits the actuation reaction force of the telescopic rod 23 to the support frame 21.

[0078] Operation process and implementation principle: During operation, the operator places the blade into the fixing groove 2. The blade can be placed through the fixing groove 2. The core function of the fixing groove 2 is to provide a stable installation base for the pressure rod 3. The fixing groove 2 on one side of the moving frame 1 provides a stable installation base for the pressure rod 3, ensuring that the pressure rod 3 is fixed in position. The pressure rod 3 can adjust the support height and pressure of the rubber wheel 4 to fix the device and the blade.

[0079] The telescopic rod 23 serves as an auxiliary fixing component and is unrelated to angle adjustment. The top of the telescopic rod 23 is fixedly connected to a support plate 27, which in turn connects to a support frame 21. The bottom is fixedly connected to a clamping ring 22. The telescopic rod 23, in conjunction with the clamping ring 22, allows for flexible adjustment of the clamping position and tightness, adapting to the auxiliary fixing needs of components of different sizes. Waste liquid generated during cleaning is collected and guided away by the guide plate 15. The entire process is automated, efficient, precise, and comprehensive.

[0080] The PLC control board 24 first controls the pressure rod 3 to press down, fixing the blades via the rubber wheel 4. Then, it controls the extension rod 23 to extend, lowering the nozzle assembly to a preset height. Next, it controls the angle adjustment shaft 8 to adjust the nozzle core 7 to the optimal spray angle. Finally, it starts the water pump 17, pumping the descaling agent from the water tank 16. After passing through the water pipe 26 and the distributor 12, the agent is split into two paths: the metal rigid pipe 11 and the high-pressure hose 10. The nozzle travels through a metal rigid pipe 11 → connecting pipe 19 → fixed pipe 25 → nozzle housing 6 → angle adjustment shaft 8, and finally enters the nozzle core 7. This path, in conjunction with the structure of the angle adjustment shaft 8, requires a rigid pipe to ensure stable delivery in a fixed direction. Another route delivers the fluid directly to the nozzle core 7 via high-pressure hose 10; this route needs to be adapted to changes in the nozzle angle. Using only a single-path delivery method may cause pressure fluctuations due to angle adjustments such as stretching / bending of the high-pressure hose 10. The fixed metal rigid pipe 11 cannot adapt to the angle. However, the splitter 12 can balance the pressure of the two-path delivery, avoiding the defects of single-path delivery.
