Description

Technical Field

[0001] This utility model specifically relates to a turbine blade cleaning device, belonging to the field of blade cleaning technology. Background Technology

[0002] As a core power equipment in fields such as power and chemical industry, steam turbine blades are key components for energy conversion. When operating in a high-temperature and high-pressure steam environment for a long time, impurities such as salt scale, oxides, and carbon deposits easily accumulate on the blade surface. This not only reduces steam flow efficiency and increases energy consumption, but may also cause malfunctions such as increased vibration and blade corrosion, directly affecting the safety and service life of the equipment. Therefore, regular cleaning and maintenance of steam turbine blades is a necessary measure to ensure the stable and efficient operation of the unit.

[0003] Currently, turbine blade cleaning typically employs a single-sided cleaning method. While this method can meet certain cleaning requirements, when faced with the need for double-sided cleaning, after cleaning one side, the blade needs to be unsecured and disassembled. After disassembly, it needs to be manually flipped over and secured again before it can be rinsed. The entire process is cumbersome, requiring a significant amount of time and effort during cleaning. This repetitive disassembly, flipping, and reassembly significantly increases the time required for double-sided cleaning and severely reduces work efficiency.

[0004] To address the above problems, this application proposes a turbine blade cleaning device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a turbine blade cleaning device. Through the design of a double-sided cleaning mechanism, a hydraulic cylinder drives a clamping plate to cooperate with a rotating plate. Rubber anti-slip pads ensure stable clamping of the blades. A rotary motor drives the rotating plate to rotate, causing the blades to rotate and switch cleaning positions. When the horizontal water pipe rotates, the nozzles can adjust the spray angle according to the blade tilt angle, allowing the cleaning fluid to enter the blade gaps. As the blades rotate, the upper and lower nozzles simultaneously clean both the front and back surfaces of the blades, completing double-sided cleaning without the need for disassembly and reassembly, significantly improving work efficiency and solving the problems mentioned in the background art.

[0006] A turbine blade cleaning device includes: a double-sided cleaning mechanism, comprising a blade mounting assembly and an adjustable flushing assembly; the blade mounting assembly includes a sealed box, with a base installed below the sealed box, a water storage chamber for collecting flushing wastewater being provided inside the base, and a filter plate for filtering wastewater being installed above the water storage chamber, a motor cylinder being provided above the filter plate, and a rotatable rotating plate being provided above the motor cylinder, and a clamping block being provided above the rotating plate that can be raised and lowered to cooperate with the rotating plate to clamp the middle part of the turbine blade, and rubber anti-slip pads for increasing clamping friction being installed on the opposite side of the rotating plate and the clamping block; the cleaning mechanism includes horizontal water pipes respectively arranged on both sides of the rotating plate with adjustable flushing angles, and multiple sets of nozzles for rinsing and cleaning the blades being installed on the side of the horizontal water pipes closest to the rotating plate.

[0007] In a preferred embodiment, the filter plate has multiple sets of through holes on its surface, and a drain valve is installed at the rear of the base, with the drain valve and the through holes communicating with the inside of the water storage chamber.

[0008] In a preferred embodiment, the front of the enclosed box is provided with two sets of doors, and the two sets of doors are connected to the enclosed box by hinges, and the two sets of doors are double-opening.

[0009] In a preferred embodiment, a fixed base is installed in the middle of the upper part of the filter plate, and a motor cylinder is installed above the fixed base. A rotary motor is installed inside the motor cylinder, and the output shaft of the rotary motor is connected to a rotating plate. The rotating plate is rotatably connected to the upper end of the motor cylinder.

[0010] In a preferred embodiment, a hydraulic cylinder is mounted above the clamping block, and the piston rod of the hydraulic cylinder is rotatably connected to the clamping block.

[0011] In a preferred embodiment, a fixed frame is provided above the interior of the enclosed box, and the lower end of the fixed frame is fixedly connected to the base. The upper end of the hydraulic cylinder is fixedly connected to the fixed frame via a connecting rod.

[0012] In a preferred embodiment, each of the two sets of horizontal water pipes is provided with a set of fixed support plates on the side away from the rotating plate, and the lower end of the fixed support plate is fixedly connected to the base. The two sets of fixed support plates are arranged opposite each other with the rotating plate as the center. The fixed support plates have a height difference and make the spray positions of the nozzles opposite each other. One side of the horizontal water pipe is rotatably connected to the fixed support plate.

[0013] In a preferred embodiment, a main gear is provided on one side of the fixed support plate, and a waterproof motor is provided on the other side. An auxiliary gear is meshed with one side below the main gear, and the auxiliary gear is fixedly connected to the outer wall of the horizontal water pipe. The output shaft of the waterproof motor is connected to the main gear.

[0014] As a preferred embodiment, an external water pipe is installed at the end of the horizontal water pipe near the waterproof motor, and one end of the external water pipe passes through the enclosed box.

[0015] Beneficial effects:

[0016] 1. By designing a blade mounting assembly, the blade is placed stably on the rotating plate. The hydraulic cylinder drives the clamping plate to descend vertically, forming a fastening structure that links the upper and lower parts of the rotating plate. Rubber anti-slip pads are embedded on the inner side of the clamping plate and the surface of the rotating plate to increase friction and achieve stable clamping of the blade. The blade can maintain its position even during rinsing. After fixing, the rotary motor drives the rotating plate to make the blade rotate freely. The rinsing position of the blade can be quickly switched by rotating. At the same time, the clamping block rotates synchronously with the blade to ensure that the blade is always reliably fixed throughout the cleaning process, thus improving cleaning efficiency.

[0017] 2. By designing an adjustable flushing component, when the main gear rotates, it drives the auxiliary gear to rotate, which in turn drives the two sets of horizontal water pipes to rotate. This allows the nozzles installed on them to adjust the spray angle according to the tilt angle of the turbine blades, enabling the cleaning liquid to enter the blade gaps for cleaning. During the blade rotation, the upper nozzles flush and clean the dirt on the upper surface of the blades, while the lower nozzles flush the dirt on the lower surface of the blades. The double-sided flushing is carried out simultaneously, and double-sided cleaning can be completed without disassembling the blades. This innovative design eliminates the need for a cumbersome disassembly and reassembly process, and significantly improves the efficiency of blade cleaning through angle adjustment and simultaneous double-sided operation.

[0029] Please see Figures 3-4 As shown, a hydraulic cylinder 110 is installed above the clamping block 111, and the piston rod of the hydraulic cylinder 110 is rotatably connected to the clamping block 111. When the blade is clamped and rotated, the clamping block 111 can rotate synchronously with the blade under the action of the blade rotation.

[0030] Please see Figures 3-4 As shown, a fixed frame 112 is provided inside the upper part of the enclosed box 11, and the lower end of the fixed frame 112 is fixedly connected to the base 13. The upper end of the hydraulic cylinder 110 is fixedly connected to the fixed frame 112 through a connecting rod.

[0031] Please see Figures 3-5 As shown, each of the two sets of horizontal water pipes 21 is provided with a set of fixed support plates 23 on the side away from the rotating plate 19, and the lower end of the fixed support plate 23 is fixedly connected to the base 13.

[0032] Please see Figures 3-5 As shown, a main gear 24 is provided on one side of the fixed support plate 23, and a waterproof motor 26 is provided on the other side.

[0034] In practical use, the working principle of this utility model is as follows:

[0035] First, open the double-leaf door 12 on the front of the sealed box 11, and place the turbine blades on the rotating plate 19, aligning the center of the blades with the rotating plate 19. Then, the hydraulic cylinder 110 drives the clamping block 111 to descend, cooperating with the rotating plate 19 and using rubber anti-slip pads to firmly clamp the center of the blades. Next, the waterproof motor 26 starts, and its output shaft drives the main gear 24 to rotate. The main gear 24 drives the auxiliary gear 25 to rotate through meshing transmission, which in turn causes the two sets of horizontal water pipes 21 to rotate. This allows the tilt of the nozzles 22 to be adjusted according to the tilt of the blades, so that the liquid sprayed from the nozzles 22 can enter the gaps between the blades. After adjustment, the external water pipe 27 is opened. Connected to an external water pump, the tank door 12 is then closed. The water pump pumps the cleaning liquid into the horizontal water pipe 21, causing the cleaning liquid to be sprayed out towards the blades through the nozzle 22. The rotating motor drives the rotating plate 19 to rotate the blades and switch the cleaning area. The nozzle 22 of the upper horizontal water pipe 21 rinses the upper surface of the blades, and the nozzle 22 of the lower horizontal water pipe 21 rinses the lower surface of the blades. At the same time, the cleaning liquid can penetrate the gap between the blades, thereby achieving double-sided cleaning. The wastewater generated by rinsing is filtered through the through holes of the filter plate 16 and flows into the water storage chamber 15 of the base 13, which can be discharged through the drain valve 14. The entire process does not require disassembling and reassembling the blades again, and the cleaning operation is completed efficiently and conveniently.
