Description

Technical Field

[0001] This utility model relates to the field of water turbine maintenance technology, specifically a water turbine runner maintenance device. Background Technology

[0002] A water turbine is a power machine that converts water energy into mechanical energy. It is mainly used in hydroelectric power stations to drive generators to generate electricity. Its core principle is to use the water flow to impact or push the runner blades to make the runner rotate, and then output mechanical work through the main shaft. The water turbine runner maintenance device is a collection of special equipment or tools used for the maintenance, inspection and repair of water turbine runners, which aims to ensure the efficient and safe operation of the runner.

[0003] The existing patent authorization announcement number CN218698621U discloses a turbine runner maintenance device, which uses a hydraulic cylinder to drive the lifting platform to rise and fall, thereby lifting the runner. This allows maintenance personnel to lie on the workbench and clean both sides of the runner blades, improving work efficiency. The runner can rotate freely on the lifting platform, allowing maintenance personnel to clean the runner from their own workstation without having to clean around the runner, simplifying the work, reducing labor efficiency, and avoiding fatigue caused by maintenance personnel constantly standing up and squatting.

[0004] In the aforementioned patent, the rotating wheel generates a large amount of waste during cleaning, which falls everywhere on the base platform. After the rotating wheel cleans, a lot of time is still needed to clean the waste on the base platform, which reduces work efficiency and increases labor intensity. Utility Model Content

[0005] The purpose of this utility model is to provide a turbine runner maintenance device to solve the problem mentioned in the background art that garbage falls everywhere on the base platform, and after cleaning the runner, a lot of time still needs to be spent cleaning the garbage on the base platform, which reduces work efficiency and increases labor intensity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a turbine runner maintenance device, comprising a base, a collecting trough at the top of the base, a waste discharge port communicating with the collecting trough at the bottom of the collecting trough, a vertical cylinder fixedly connected to the center of the collecting trough, a lifting hydraulic cylinder fixedly installed inside the vertical cylinder, a support chuck movably sleeved on the top of the lifting hydraulic cylinder, and a collection assembly and an auxiliary assembly provided on the outside of the base; the collection assembly includes a flushing pipe fixedly installed on the upper edge of the inner side of the collecting trough, flushing heads equidistantly arranged in a ring around the collecting trough on the inner side of the flushing pipe, a water inlet pipe fixedly connected to the outer wall of the flushing pipe, and a filter mechanism fixedly installed at the bottom of the base below the waste discharge port, with a return water pipe fixedly connected to the bottom of the filter mechanism.

[0007] Preferably, the collecting trough is funnel-shaped, and the inner wall of the collecting trough is coated with an organosilicon coating.

[0008] Preferably, the waste discharge port is arranged in a ring shape at equal intervals around the outside of the vertical cylinder.

[0009] Preferably, the flushing head is inclined toward the collection tank.

[0010] Preferably, the filtration mechanism includes a filter box fixedly connected to the bottom of the base, an inclined filter plate fixedly snapped into the inside of the filter box, an outlet adapted to the lower side of the filter plate on the side of the filter box, a pushing hydraulic cylinder fixedly installed on the outside of the filter box away from the outlet, a push plate conforming to the surface of the filter plate fixedly installed on the outside of the telescopic end of the pushing hydraulic cylinder, and a collection box placed below the outlet.

[0011] Preferably, a rubber scraper is fixedly installed at the bottom of the pushing hydraulic cylinder.

[0012] Preferably, the auxiliary component includes a first support ring, a second support ring, and a support plate. The first support ring and the second support ring are fixedly installed on the outer side wall of the base and the vertical cylinder, respectively. The first support ring and the second support ring are flush with the height of the base. The support plate is clamped above the first support ring and the second support ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Water is supplied through the inlet pipe into the flushing pipe and sprayed from the flushing head onto the wall of the collection tank. The water body forms a flowing water curtain on the collection tank. Impurities and garbage fall into the collection tank and flow with the water curtain to the waste outlet. They are discharged from the waste outlet and enter the filtration mechanism to filter impurities. After the impurities are filtered, the waste is discharged from the return water pipe for recycling. This makes it convenient to clean up impurities during cleaning without the need for personnel to spend time cleaning separately, thus improving work efficiency.

[0015] 2. The pusher plate is driven by the hydraulic cylinder to slide along the surface of the filter plate, pushing the garbage and impurities accumulated on the top of the filter plate toward the outlet and out into the collection box for collection, which facilitates subsequent cleaning and ensures that the surface of the filter plate is always unobstructed, avoiding the filtration effect due to impurities clogging the filter.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a turbine runner maintenance device, including a base 1, a collection trough 11 on the top of the base 1, a waste discharge port 12 communicating with the bottom of the collection trough 11, a vertical cylinder 2 fixedly connected to the center of the collection trough 11, a lifting hydraulic cylinder 3 fixedly installed inside the vertical cylinder 2, a support chuck 4 movably sleeved on the top of the lifting hydraulic cylinder 3, and a collection assembly 5 and an auxiliary assembly 6 arranged outside the base 1; the collection assembly 5 includes a flushing pipe 51 fixedly installed on the upper edge of the inner side of the collection trough 11, flushing heads 52 arranged circumferentially around the collection trough 11 at equal intervals on the inner side of the flushing pipe 51, and the outer side of the flushing pipe 51... A water inlet pipe 53 is fixedly connected to the side wall. A filter mechanism 54 located below the waste outlet 12 is fixedly installed at the bottom of the base 1. A return water pipe 55 is fixedly connected to the bottom of the filter mechanism 54. The water is supplied by an external water source through the water inlet pipe 53, enters the flushing pipe 51, and is sprayed onto the wall of the collection tank 11 from the flushing head 52. The water body forms a flowing water curtain on the collection tank 11. Impurities and garbage fall into the collection tank 11 and flow with the water curtain to the waste outlet 12. They are discharged from the waste outlet 12 and enter the filter mechanism 54 to filter the impurities. The filtered impurities are then discharged from the return water pipe 55 for recycling. This makes it convenient to clean the impurities during cleaning without the need for personnel to spend time cleaning separately, thus improving work efficiency.

[0024] The collecting tank 11 is funnel-shaped, and its inner wall is coated with an organosilicon coating. The inclined angle of the funnel-shaped structure can accelerate the speed at which impurities gather towards the waste outlet 12 under the action of water flow. The organosilicon coating on the inner wall can significantly reduce the frictional resistance between the water and the tank wall, and at the same time reduce the probability of impurities adhering to the surface of the tank wall, ensuring that impurities are discharged more smoothly with the water flow. This further improves the efficiency of collecting and guiding impurities in the collecting tank 11. It works well with the spraying function of the flushing pipe 51 and the flushing head 52 to jointly ensure the high efficiency and thoroughness of the impurity cleaning process.

[0025] The waste discharge ports 12 are arranged in a ring shape with equal spacing around the outside of the vertical cylinder 2. This ensures that impurities flowing down from different directions in the collection tank 11 can quickly enter the corresponding waste discharge ports 12. This avoids the problem of impurities accumulating locally in the tank due to the limited location of a single waste discharge port 12. At the same time, the equidistant arrangement makes the water flow distribution of each waste discharge port 12 more uniform, reduces the scouring dead angle caused by the water flow concentrating in a certain area, and speeds up the discharge of impurities.

[0026] The flushing head 52 is inclined toward the collecting tank 11. The angle of inclination is optimized so that the flushing water is sprayed onto the inner wall surface of the collecting tank 11 at the best angle, ensuring that the water flow covers all areas of the tank wall. When the water flow impacts the tank wall, it forms an oblique scouring force, which can not only directly remove stubborn impurities attached to the tank wall, but also push the impurities along the inclined direction of the collecting tank 11 toward the waste outlet 12. This forms a synergistic effect with the guiding effect of the collecting tank 11 itself, further improving the comprehensiveness and efficiency of impurity cleaning.

[0027] Auxiliary component 6 includes a first support ring 61, a second support ring 62, and a support plate 63. The first support ring 61 and the second support ring 62 are fixedly installed on the outer walls of the base 1 and the vertical cylinder 2, respectively. Both the first support ring 61 and the second support ring 62 are flush with the height of the base 1. The support plate 63 is positioned above the first support ring 61 and the second support ring 62. By securing both ends of the auxiliary component 6 to the first support ring 61 and the second support ring 62 from above, cleaning personnel can lie on the support plate 63 and clean the lower end face of the rotating wheel from below, eliminating the need for complex fixing steps. The bearing plate 63 can be quickly and stably placed, and it is easy for cleaning personnel to adjust its position or disassemble it at any time according to maintenance needs. The bearing plate 63 is made of high-strength lightweight alloy material, which effectively reduces the overall weight while ensuring sufficient load-bearing capacity. When the cleaning personnel lie on the bearing plate 63, their body center of gravity can be evenly distributed to the base 1 and the vertical cylinder 2 through the bearing plate 63. In addition, the anti-slip texture set on the surface of the bearing plate 63 can significantly improve the stability and safety during the operation, allowing the cleaning personnel to focus more on cleaning key parts such as the blade gap and hub surface on the lower end face of the impeller.

[0028] Please see Figure 2 and Figure 5 The filtration mechanism 54 includes a filter box 541 fixedly connected to the bottom of the base 1. An inclined filter plate 542 is fixedly engaged inside the filter box 541. A discharge port 543, adapted to the lower side of the filter plate 542, is opened on the side of the filter box 541. A pushing hydraulic cylinder 544 is fixedly installed on the outside of the filter box 541 away from the discharge port 543. A pushing plate 545, conforming to the surface of the filter plate 542, is fixedly installed on the outside of the telescopic end of the pushing hydraulic cylinder 544. A collection box 546 is placed below the discharge port 543. Impurities and waste falling onto the filter plate 542 are intercepted. The pushing mechanism is controlled by a timer. Hydraulic cylinder 544 drives push plate 545 to slide along the surface of filter plate 542, pushing the accumulated debris on the top of filter plate 542 towards outlet 543 and out. The debris eventually falls into collection box 546 for collection, facilitating subsequent cleaning. The tilt angle design of filter plate 542 can use gravity to assist the debris in sliding towards outlet 543, reducing the pushing resistance of push plate 545. The extension and retraction frequency of push hydraulic cylinder 544 can be flexibly adjusted according to the amount of debris accumulation during actual maintenance, ensuring that the surface of filter plate 542 remains unobstructed and avoiding filtration effect due to debris blockage.

[0029] A rubber scraper is fixedly installed at the bottom of the pushing hydraulic cylinder 544. As the pushing plate 545 moves with the pushing hydraulic cylinder 544, the rubber scraper can scrape off the fine impurities remaining on the surface of the filter plate 542, thereby improving the cleanliness of the filter plate 542. The rubber material has good elasticity and wear resistance, which can not only ensure the scraping effect, but also avoid causing hard damage to the surface of the filter plate 542, thus extending the service life of the filter plate 542.

[0030] Working principle: The rotating wheel is hoisted and placed flat on the support chuck 4 above the base 1. The position of the rotating wheel is adjusted by the equidistantly arranged claws on the support chuck 4 along the radially arranged mounting holes on the support chuck 4. The rotating wheel is fixed by bolts, thereby limiting and fixing the rotating wheel from the inside of the rotating wheel shaft hole. The workers clean the upper part of the rotating wheel from above. The ball bearings between the support chuck 4 and the lifting hydraulic cylinder 3 can rotate along the axis of the lifting hydraulic cylinder 3, which can drive the rotating wheel to rotate. This eliminates the need for maintenance personnel to move around the rotating wheel frequently, which is convenient for cleaning work. After cleaning, the lifting hydraulic cylinder 3 is controlled to push the support chuck 4, which in turn pushes the rotating wheel to rise, increasing the distance between the base 1 and the rotating wheel. Then, the two ends of the auxiliary component 6 are clamped on the support ring 61 and the support ring 62 from above. The cleaning personnel lie on the bearing plate 63 and clean the lower end face of the rotating wheel from below.

[0031] During cleaning, an external water source is connected through the inlet pipe 53. Water enters the flushing pipe 51 through the inlet pipe 53 and is sprayed onto the wall of the collection tank 11 from the annular flushing head 52. The water forms a flowing water curtain on the collection tank 11. Impurities and debris during cleaning fall into the collection tank 11 under gravity and flow with the water curtain to the waste outlet 12, where they are discharged. The impurities and debris enter the filter box 541 from the waste outlet 12 and fall onto the filter plate 542. The filter plate 542 intercepts the impurities and debris, and the water passes through the filter plate 542. 42 enters the lower part of the filter box 541 and is discharged through the return water pipe 55 for recycling. By controlling the timing, the pusher hydraulic cylinder 544 pushes the pusher plate 545 to slide along the surface of the filter plate 542. The pusher plate 545 pushes the garbage and impurities accumulated on the top of the filter plate 542 to move towards the discharge port 543 and pushes them out, so that the garbage and impurities fall into the collection box 546 for collection, which is convenient for later cleaning. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
