Description

Technical Field

[0001] This utility model relates to the field of nuclear power turbine model production technology, specifically a nuclear power turbine model coating device. Background Technology

[0002] Nuclear power plant impeller models are scaled-down versions of impellers actually used in nuclear power plants. They are used to simulate and test the impeller's performance under different operating conditions. As a key component of the nuclear power plant's power conversion system, nuclear power plant impellers are coated with a film. Coating is a surface treatment technology widely used in industry. By spraying specific coatings or thin film materials onto the surface of an object, a protective, decorative, or other special function film is formed. In the application scenario of nuclear power plant impeller models, the main purpose of coating is to improve the impeller model's wear resistance, corrosion resistance, and fatigue resistance, ensuring that it can accurately reflect the working characteristics of the actual nuclear power plant impeller during simulation operation, while extending the model's service life.

[0003] Currently, traditional methods of coating nuclear power turbine models have many problems. In the placement of the model, it mostly relies on simple manual fixing, which makes it difficult to guarantee the model's stability and precise positioning during the coating process. This leads to displacement of the model during subsequent coating operations, resulting in uneven coating thickness and affecting coating quality. Existing coating equipment typically only allows for simple up-and-down movement of the atomizing nozzle or fixed-position spraying. When faced with the complex curved surface structure of nuclear power turbine models, this single spraying method cannot cover the model surface comprehensively, significantly reducing the model's protective performance and failing to meet the stringent requirements of actual nuclear power turbine operation. Moreover, fixing the nozzle during spraying, as it cannot dynamically adjust according to the model's shape and position, easily leads to waste of spraying material and increases production costs. Therefore, we propose a nuclear power turbine model coating device. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for nuclear power turbine models, addressing the numerous problems existing in traditional nuclear power turbine model coating methods mentioned in the background. In the placement of the nuclear power turbine model, manual fixation is often used, making it difficult to ensure the model's stability and precise positioning during the coating process. This leads to model displacement during subsequent coating operations, resulting in uneven coating thickness and affecting coating quality.

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.

[0036] Please see Figures 1-12 This utility model provides a technical solution: a coating device for a nuclear power turbine model, including a working plate 1, several support columns 2 fixed at the bottom end of the working plate 1, a spraying box 5 fixed on the top surface of the working plate 1, a door 6 hinged to the front surface of the spraying box 5 near the top end by two hinges, and a handle 7 installed on the front surface of the door 6, and further including:

[0037] The placement mechanism 8 is located on the bottom surface of the spraying box 5 near the middle position and is used to place the nuclear power turbine model. The placement mechanism 8 includes a base plate 81 fixed to the bottom surface of the spraying box 5 by several fixed columns 82, a rotating roller 83 rotatably connected to the top surface of the base plate 81, a turntable 84 coaxially fixed to the top surface of the rotating roller 83 and used to place the nuclear power turbine model, several guide rods 85 fixed to the bottom surface of the turntable 84 and slidably connected to the top surface of the base plate 81, and a rotary motor 89 installed on the top surface of the base plate 81 and used to drive the rotating roller 83 to rotate.

[0038] The coating mechanism 9, located inside the spraying box 5, is used to spray the nuclear power turbine model placed on the top surface of the turntable 84. The coating mechanism 9 includes a liquid-conducting box 91 located near the top inside the spraying box 5, a rotating pipe 92 rotatably connected to the bottom surface of the liquid-conducting box 91 and communicating with its inner cavity, two pulleys 97 located below the liquid-conducting box 91 for driving the rotating pipe 92 to rotate, a spraying motor 99 mounted on the bottom surface of the liquid-conducting box 91 for driving the two pulleys 97 to rotate, and a spraying motor 99 mounted on the top surface of the spraying box 5 for spraying the liquid-conducting machine. The liquid box 91 provides a pump body 913 for spraying material, and an electric cylinder 94 mounted on the top surface of the spraying box 5 for driving the liquid box 91 to move up and down. Atomizing nozzle 93, connected to the inner cavity of the rotating pipe 92 and located directly above the turntable 84, is fixed at the bottom. Two pulleys 97 are connected by a belt 98. The placement mechanism 8 enables the nuclear power turbine model to be placed and rotated on the turntable 84, ensuring that different parts of the model receive uniform spraying during the coating process, improving the comprehensiveness and uniformity of the coating. The rotary motor 89 in the placement mechanism 8 drives the rotating roller 83 to rotate, which in turn drives the turntable 84 and the nuclear power turbine model on it to rotate. Simultaneously, the guide rod 85 and guide groove cooperate to ensure the stability of the rotation. Through the coating mechanism 9, the atomizing nozzle 93 rotates while spraying the material, achieving a more thorough coating operation on the nuclear power turbine model, improving the coating quality and efficiency. The spraying motor 99 in the coating mechanism 9 drives the pulley 97 to rotate, which in turn drives the rotating tube 92 and the atomizing nozzle 93 to rotate. The pump body 913 provides the spraying material. The electric cylinder 94 can adjust the height of the liquid box 91 and the atomizing nozzle 93 to accommodate models of different sizes.

[0039] In this embodiment, the piston rod of the electric cylinder 94 penetrates the top surface of the spray box 5 and extends into the interior of the spray box 5 near the top. A gasket 95 is fixed between the bottom surface of the piston rod of the electric cylinder 94 and the top surface of the liquid box 91. The placement mechanism 8 also includes two gears 88 located between the base plate 81 and the turntable 84 and meshing with each other, and a rotating shaft 810 coaxially connected to the output shaft of the rotating motor 89. The two gears 88 are respectively coaxially fixed on the outer circumference of the rotating shaft 810 and the rotating roller 83. The coating mechanism 9 also includes a spraying shaft coaxially connected to the output shaft of the spraying motor 99. 910, and two pulleys 97 are coaxially fixed on the outer circumference of the spraying shaft 910 and the rotating pipe 92, respectively, so that the liquid box 91 can be raised and lowered, and the spraying position can be adjusted according to the height of the nuclear power turbine model. By setting two meshing gears 88 and the rotating shaft 810, the power of the rotating motor 89 can be effectively transmitted to the rotating roller 83, ensuring that the turntable 84 drives the nuclear power turbine model to rotate stably. By setting the spraying shaft 910 and two pulleys 97, the power of the spraying motor 99 can be transmitted to the rotating pipe 92, driving the atomizing nozzle 93 to rotate.

[0040] In addition, the top surface of the spray box 5 is provided with an installation hole that communicates with its inner cavity. The left side surface of the liquid box 91 is fixed with an inlet pipe 912 that communicates with its inner cavity. The outlet end of the pump body 913 is tightly fitted with an L-shaped liquid pipe 914. The vertical end of the liquid pipe 914 is fixed in the installation hole on the top surface of the spray box 5. The liquid pipe 914 and the inlet pipe 912 are connected by a corrugated pipe 915, so that the pump body 913 can smoothly deliver the spraying material into the liquid box 91. The corrugated pipe 915 can adapt to the lifting and lowering of the liquid box 91.

[0041] Furthermore, a support plate 3 is fixed to the bottom of the support column 2, and an anti-slip plate 4 that matches the shape of the support plate 3 is fixed to the bottom of the support plate 3. The anti-slip plate 4 has anti-slip texture on its bottom surface, which increases the contact area and friction between the support column 2 and the ground, making the entire device more stable and less prone to sliding.

[0042] Furthermore, the top surface of the base plate 81 is provided with an annular guide groove, and the bottom surface of the guide rod 85 is fixed with a guide block 86 that is slidably connected to the guide groove on the top surface of the base plate 81, to ensure the stability of the turntable 84 when it rotates, thereby ensuring the stability of the placement and rotation of the nuclear power turbine model.

[0043] Specifically, the atomizing nozzle 93 is positioned and matched with the turntable 84. The top surface of the turntable 84 is provided with a mounting groove, and a magnetic suction plate 87 is embedded inside the mounting groove. By setting the atomizing nozzle 93 to be positioned and matched with the turntable 84, the spraying material can be accurately sprayed onto the nuclear power turbine model. By setting the magnetic suction plate 87, the nuclear power turbine model can be magnetically attracted, making it more stable on the turntable 84.

[0044] It is worth noting that the placement mechanism 8 also includes a motor box 811 fixed to the top surface of the base plate 81, with the rotary motor 89 located inside the motor box 811. The coating mechanism 9 also includes a protective box 911 fixed to the bottom surface of the liquid box 91 and a protective cylinder 96 fixed to the top surface of the spray box 5. The cylinder body of the electric cylinder 94 is located inside the protective cylinder 96, and the spray motor 99 is located inside the protective box 911. The spray shaft 910 passes through the bottom surface of the protective box 911. By setting the motor box 811, the rotary motor 89 is placed inside, which can protect the rotary motor 89 and prevent it from being damaged by external factors. By setting the protective box 911 and the protective cylinder 96, the cylinder bodies of the spray motor 99 and the electric cylinder 94 are placed inside, which can protect the spray motor 99 and the electric cylinder 94 and extend their service life.

[0045] It is worth noting that a discharge pipe 10 connected to the inner cavity of the spray box 5 is fixed near the bottom of the front surface. A manual valve 11 is installed on the outer wall of the discharge pipe 10. A sealing ring is provided at the part of the discharge pipe 10 that contacts the spray box 5. Sealing rings are also provided at the parts of the liquid pipe 914 that contact the pump body 913 and the liquid inlet pipe 912. Sealing rings are also provided at the parts of the liquid box 91 that contact the liquid inlet pipe 912 and the rotating pipe 92. A sealing ring is also provided at the part of the rotating pipe 92 that contacts the atomizing nozzle 93. By setting up the discharge pipe 10 and the manual valve 11, it is convenient to discharge excess spraying material or waste in the spray box 5. By setting sealing rings at each contact point, leakage of spraying material can be prevented, ensuring the sealing and normal operation of the device.

[0046] It is worth emphasizing that the longitudinal section of the guide groove on the top surface of the base plate 81 is a convex cross section, and the shape of the guide block 86 is a convex shape that matches the shape of the guide groove on the top surface of the base plate 81. This further enhances the stability of the guide rod 85 sliding on the base plate 81, prevents the guide rod 85 from disengaging from the guide groove, and ensures the smoothness of the rotation of the turntable 84.

[0047] It should be added that the rotary motor 89, electric cylinder 94, spraying motor 99, and pump body 913 are all electrically connected to the external PLC via wires, and the rotary motor 89, electric cylinder 94, spraying motor 99, and pump body 913 are all electrically connected to the external power supply via wires, and the external PLC is also electrically connected to the external power supply via wires.

[0048] Finally, it should be noted that the rotary motor 89, electric cylinder 94, spraying motor 99, pump body 913, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0049] In the specific use of this embodiment, when it is necessary to perform a coating operation on the nuclear power turbine model, the entire device is stably placed on the work site by the support plate 3 at the bottom of the support column 2 and the anti-slip plate 4. The anti-slip texture on the bottom surface of the anti-slip plate 4 increases the friction with the ground, ensuring that the device will not easily slide during operation. The staff first opens the box door 6 on the front side of the spray box 5, which is hinged by a hinge. Its handle 7 makes it convenient for the operator to open and close the box door 6.

[0050] Next, the nuclear power turbine model is placed on the top surface of the magnetic plate 87. The magnetic attraction of the magnetic plate 87 secures the model firmly to the turntable 84. Then, the liquid supply pipe of the external coating supply device is tightly connected to the inlet end of the pump body 913. Subsequently, the electric cylinder 94 is activated via an external PLC. The piston rod of the electric cylinder 94 moves, causing the liquid passage box 91, which is fixed to it via a gasket 95, to move downwards. The movement of the liquid passage box 91, in turn, causes the rotating pipe 92 and the atomizing nozzle 93 to move downwards. When the atomizing nozzle 93 reaches a suitable position above the nuclear power turbine model, the external PLC... After the electric cylinder 94 is turned off, the spraying motor 99, pump body 913 and rotary motor 89 are started by the external PLC. The output shaft of the rotary motor 89 drives the rotary shaft 810 to rotate. The gear 88 on the rotary shaft 810 meshes with the gear 88 on the roller 83, thereby transmitting power to the roller 83, causing the roller 83 to rotate on the base plate 81. The roller 83 drives the coaxially fixed turntable 84 to rotate. At the same time, the guide rod 85 on the bottom surface of the turntable 84 slides in the annular guide groove on the top surface of the base plate 81 through the guide block 86, ensuring the stability of the rotation of the turntable 84, thereby driving the nuclear power turbine model to rotate.

[0051] Meanwhile, after the pump body 913 is started, the spraying material in the external coating device is transported from its liquid supply pipe to the liquid passage pipe 914. The spraying material is then transported to the liquid passage box 91 through the liquid passage pipe 914, the corrugated pipe 915 and the liquid inlet pipe 912. The spraying material in the liquid passage box 91 is transported to the atomizing nozzle 93 through the rotating pipe 92. The atomizing nozzle 93 atomizes the spraying material and sprays it onto the rotating nuclear power turbine model. At this time, the output shaft of the spraying motor 99 drives the spraying shaft 910 to rotate. The pulley 97 on the spraying shaft 910 drives the pulley 97 on the rotating pipe 92 to rotate through the belt 98, thereby causing the rotating pipe 92 to drive the atomizing nozzle 93 to rotate. Since the nuclear power turbine model rotates under the drive of the placement mechanism 8, and the atomizing nozzle 93 rotates and rises and falls under the drive of the coating mechanism 9, the coating operation on the nuclear power turbine model can be performed more fully.

[0052] After the coating work is completed, the rotary motor 89, the spraying motor 99 and the pump body 913 are turned off by the external PLC. If there is excess spraying material or waste in the spraying box 5, the manual valve 11 on the discharge pipe 10 can be opened to discharge it. The sealing rings of the discharge pipe 10, the spraying box 5 and the various connecting parts ensure the sealing of the device and prevent the spraying material from leaking.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
