Technical Field

[0001] This utility model relates to the field of high-risk operation technology in thermal power plants, and in particular to a simulation model of high-risk operation scenarios in thermal power plants. Background Technology

[0002] A high-risk operation scenario simulation model for thermal power plants is a specially designed physical model that accurately reproduces specific areas or equipment within a thermal power plant that may involve high-risk operations, such as boilers, steam turbines, and transformers. This model serves to visually demonstrate the structure and working principles of a thermal power plant, helping users understand the operational procedures and safety risks of complex systems. Simultaneously, it also functions as a teaching and training tool, allowing operators to practice operations and conduct emergency response training in a safe environment, thereby improving their safety awareness and operational skills in actual work.

[0003] In current applications of high-risk operation simulation models for thermal power plants, a large amount of dust accumulates on the surface of the model after prolonged operation, severely affecting the realism and accuracy of the simulation. Traditional cleaning methods primarily rely on manual cleaning to address this issue. However, this method has significant drawbacks: firstly, manual cleaning is inefficient and time-consuming, failing to meet the need for rapid restoration of the simulation's realism; secondly, during manual cleaning, personnel are prone to accidentally touching the model, causing structural damage or reduced accuracy, thus increasing maintenance costs and the frequency of updates. Utility Model Content

[0004] One objective of this invention is to propose a simulation model for high-risk operation scenarios in thermal power plants. This invention addresses the following issues mentioned in the background: on the one hand, manual cleaning is inefficient and time-consuming, making it difficult to meet the need for quickly restoring the realism of the simulated scenario; on the other hand, during manual cleaning, cleaning personnel are prone to accidentally touching the model, causing damage to the model structure or a reduction in accuracy, thereby increasing the maintenance cost and update frequency of the model.

[0005] According to an embodiment of this utility model, a high-risk operation scenario simulation model for thermal power plants includes an outer casing and a model box. The model box is fixedly installed inside the outer casing, and the model body is detachably installed inside the model box via bolts. A drive motor is installed on one corner of the outer surface of the outer casing, and a threaded screw is connected to the output end of the drive motor. Sliding grooves are provided on the upper ends of both sides of the outer casing. The threaded screw is rotatably connected to the inside of the sliding groove. A sliding block is threadedly connected to the surface of the threaded screw. A U-shaped block is fixedly connected to the inner side of the sliding block. A blower is fixedly connected to one side of the U-shaped block, and a dust collection device is fixedly connected to the other side of the U-shaped block. Several dust collection ports are installed on the lower surface of the dust collection device, and a self-resetting box cover is hinged to one end of the lower surface of the dust collection device.

[0006] Preferably, two threaded screws are provided, and a transmission gear is fixedly connected to one end of the surface of each of the two threaded screws.

[0007] Preferably, the transmission gears are interconnected via a transmission belt.

[0008] Preferably, the surface of the transmission belt has a plurality of through holes.

[0009] Preferably, the surface of the self-resetting box cover has a top opening.

[0010] Preferably, a top rod is fixedly connected to the upper end of the inner surface of the outer casing.

[0011] Preferably, the top rod and the top opening are positioned correspondingly.

[0012] Preferably, a guide block is obliquely installed at one end of the lower inner surface of the outer casing, and a cleaning port is provided through the lower end of one side surface of the outer casing.

[0013] Preferably, a bottom plate and a side baffle are fixedly connected to the lower surface of the model box, a slide rail is provided on the surface of the side baffle, a hydraulic rod is fixedly connected to the inner surface of the outer box, a transmission block is fixedly connected to the telescopic end of the hydraulic rod, and slide rods are fixedly connected to both sides of the transmission block, and the slide rods are slidably connected inside the slide rail.

[0014] Preferably, the lower surface of the base plate is fixedly connected to the telescopic end of the telescopic column, and the fixed end of the telescopic column is fixedly connected to the lower inner surface of the outer casing.

[0015] The beneficial effects of this utility model are:

[0016] This invention utilizes a blower and a vacuum cleaner. When cleaning dust and other debris from the surface of a high-risk power plant operation simulation model is required, a drive motor rotates a threaded screw, causing a sliding block to slide from one end to the other inside the outer casing. During this sliding process, the blower first blows up the dust adhering to the model's surface, and then the vacuum cleaner's lower suction port sucks the blown-up dust into the vacuum cleaner. This reciprocating cycle cleans the entire model, improving cleaning efficiency and ease of model maintenance. It also avoids damage that might occur with manual cleaning, ensuring the realism of the simulation scene and the long-term stability of the model. This effectively addresses the problems of low efficiency and long cleaning times associated with manual cleaning, which struggle to quickly restore the realism of the simulation scene; and the risk of accidental damage or reduced accuracy caused by manual cleaning, which increases maintenance costs and the frequency of model updates.

[0017] This invention utilizes a structure including a top opening and a top rod. When the vacuum cleaner slides to one end of the top rod, the top rod touches the top opening, which opens the self-resetting cover. At this time, the dust collected inside the vacuum cleaner falls through the self-resetting cover and is guided by a guide block installed at one end of the outer casing. Finally, it is discharged through the cleaning port. When the vacuum cleaner moves in the opposite direction of the top rod, the self-resetting cover automatically closes due to the reset force of the spring structure, facilitating continued dust collection. This invention achieves automatic dust discharge and convenient cover reset, improving the continuous operation efficiency of the vacuum cleaner and the automation level of dust handling, while reducing manual intervention and downtime during the cleaning process.

[0018] This invention utilizes a hydraulic rod and other structures. When a high-risk operation scenario simulation model of a thermal power plant is needed for demonstration, the extension of the hydraulic rod drags the transmission block to the left, causing the slide rod to slide to the left inside the slide rail. After the slide rod slides to the far left of the slide rail, it lifts the side baffle and bottom plate upwards, thereby lifting the model box and the model body inside the model box, allowing the operator to more intuitively see the demonstration scenario. When not in use, the hydraulic rod shortens, causing the transmission block and slide rod to slide to the right. After the slide rod slides to the far right inside the slide rail, it moves the side baffle, bottom plate, and model box downwards, causing the model box and model body to retract into the outer box, which then protects the model body.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] refer to Figure 1-6A high-risk operation scenario simulation model for thermal power plants includes an outer casing 1 and a model box 2. The model box 2 is fixedly installed inside the outer casing 1. The model body 3 is detachably installed inside the model box 2 via bolts. A drive motor 4 is installed on one corner of the outer surface of the outer casing 1. The output end of the drive motor 4 is connected to a threaded screw 9. Sliding grooves 8 are opened on the upper part of both sides of the outer casing 1. The threaded screw 9 is rotatably connected inside the sliding grooves 8. A sliding block 10 is threadedly connected to the surface of the threaded screw 9. A U-shaped block 11 is fixedly connected to the inner side of the sliding block 10. A blower 12 is fixedly connected to one side of the U-shaped block 11. A dust collection device 13 is fixedly connected to the other side of the U-shaped block 11. Several dust collection ports 14 are installed on the lower surface of the dust collection device 13. A self-resetting box cover 15 is hinged to one end of the lower surface of the dust collection device 13. Through the set blower 12 and dust collection device 13, when it is necessary to simulate the high-risk operation scenario of the thermal power plant, the model can be activated. When cleaning dust and other particles from the simulated model surface, the drive motor 4 rotates the threaded screw 9, causing the sliding block 10 to slide from one end to the other inside the upper part of the outer casing 1. During the sliding process, the blower 12 first blows up the dust adhering to the model surface, and then the suction port 14 at the lower end of the vacuum cleaner 13 sucks the blown dust into the vacuum cleaner 13. This reciprocating cycle cleans the entire model, improving cleaning efficiency and the convenience of model maintenance. At the same time, it avoids damage to the model that may be caused by manual cleaning, ensuring the realism of the simulated scene and the long-term stability of the model. This effectively avoids the problems of low efficiency and long time consumption of manual cleaning, which makes it difficult to meet the need for quickly restoring the realism of the simulated scene; and the fact that during manual cleaning, cleaning personnel may accidentally touch the model, causing damage to the model structure or a reduction in accuracy, thereby increasing the maintenance cost and update frequency of the model.

[0029] Example 1: Two threaded screws 9 are provided. One end of each threaded screw 9 is fixedly connected to a transmission gear 5. The transmission gears 5 are connected to each other by a transmission belt 6. Several locking holes 7 are opened through the surface of the transmission belt 6. The two transmission gears 5 at both ends are driven to rotate synchronously and in the same direction by the transmission belt 6, so that the sliding block 10 and U-shaped block 11 in the middle can slide more smoothly.

[0030] Example 2: A top opening 16 is provided on the surface of the self-resetting cover 15. A top rod 17 is fixedly connected to the upper end of the inner surface of the outer casing 1. The top rod 17 and the top opening 16 are positioned correspondingly. A guide block 26 is obliquely installed at one end of the lower inner surface of the outer casing 1. A cleaning port 18 is provided through the lower end of one side surface of the outer casing 1. Through the structure of the top opening 16 and the top rod 17, when the vacuum cleaner 13 slides to one end of the top rod 17, the top rod 17 touches the top opening 16, and the self-resetting cover 15 is opened through the top opening 16. At this time, the vacuum cleaner 13 is concentrated inside. The collected dust will fall through the self-resetting cover 15 and be guided by the guide block 26 installed at one end of the outer box 1. Finally, it will be discharged through the cleaning port 18. When the vacuum cleaner 13 moves in the opposite direction to the top rod 17, the self-resetting cover 15 will automatically close due to the reset force of the spring structure, which facilitates the continued collection of dust. This realizes automatic dust discharge and convenient cover reset, which improves the continuous operation efficiency of the vacuum cleaner 13 and the degree of automation of dust handling, while reducing manual intervention and downtime during the cleaning process.

[0031] Example 3: A base plate 19 and a side baffle 20 are fixedly connected to the lower surface of the model box 2. A slide rail 25 is provided on the surface of the side baffle 20. A hydraulic rod 22 is fixedly connected to the inner surface of the outer box 1. A transmission block 23 is fixedly connected to the telescopic end of the hydraulic rod 22. Slide rods 24 are fixedly connected to both sides of the transmission block 23. The slide rods 24 are slidably connected inside the slide rail 25. The lower surface of the base plate 19 is fixedly connected to the telescopic end of the telescopic column 21. The fixed end of the telescopic column 21 is fixedly connected to the lower inner surface of the outer box 1. When a high-risk operation scenario simulation model of a thermal power plant is needed for demonstration, the transmission rod 22 is extended to extend the transmission rod. When block 23 is dragged to the left, slide bar 24 slides to the left inside slide rail 25. After slide bar 24 slides to the leftmost side of slide rail 25, it lifts side baffle 20 and bottom plate 19 upward, thereby lifting model box 2 and model body 3 inside model box 2, making it easier for the operator to see the demonstration scene more intuitively. When not in use, hydraulic rod 22 shortens, causing transmission block 23 and slide bar 24 to slide to the right. After slide bar 24 slides to the rightmost side inside slide rail 25, it drives side baffle 20, bottom plate 19 and model box 2 to move downward, causing model box 2 and model body 3 to retract into outer box 1, through which outer box 1 provides protection for model body 3.

[0032] In use, first start the drive motor 4, which drives the threaded screw 9 to rotate, and the sliding block 10 moves along the sliding groove 8 from one end to the other. During the movement, the blower 12 starts first, blowing up the dust on the model surface. Then, the suction port 14 of the vacuum cleaner 13 starts working, sucking the blown dust into the interior. When the vacuum cleaner 13 slides to one end of the top rod 17, the top rod 17 touches the top opening 16, automatically opening the self-resetting cover 15. The dust inside the vacuum cleaner 13 falls through the top opening 16, is guided along the guide block 26, and is finally discharged through the cleaning port 18. Subsequently, the vacuum cleaner 13 moves in the opposite direction, and the self-resetting cover 15 automatically closes under the action of the spring return force, continuing to collect dust. This process is repeated until the entire model is cleaned, achieving an efficient and automated cleaning process that avoids the inefficiency and potential damage risks of manual cleaning. When simulating high-risk operation scenarios in thermal power plants, the hydraulic rod 22 is first extended, pushing the transmission block 23 to the left and causing the slide rod 24 to slide to the left inside the slide rail 25. After the slide rod 24 reaches the leftmost position of the slide rail 25, the transmission block 23 is pushed further, causing the side baffle 20 and the bottom plate 19 to rise, lifting the model box 2 and the model inside, exposing the demonstration scene for the operator to observe directly. After the demonstration, the hydraulic rod 22 is shortened, and the transmission block 23 and the slide rod 24 slide to the rightmost side of the slide rail 25. Then, the side baffle 20, the bottom plate 19, and the model box 2 move downwards together until the model box 2 and the model body 3 are completely retracted into the outer box 1, completing the storage and protection. The entire process is simple and efficient, ensuring the use and storage of the model.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
