Description

Technical Field

[0002] In modern thermal power plants, steam turbine boilers are one of the key pieces of equipment, and real-time monitoring of their operating status is crucial to ensuring the safe and stable operation of the power plant. Traditional methods of observing steam turbine boilers mainly rely on fixed-installation observation mirrors or simple cameras, and manual periodic inspections are used to obtain information about the working conditions inside the boiler. However, as the boiler's operating time increases and operating conditions change, the harsh internal environment of the steam turbine boiler, including high temperature, high pressure, and smoke, causes dust, oil, and other impurities to easily accumulate on the surface of the observation mirrors, severely reducing the clarity of observation and even causing misjudgments. Operators need to frequently stop the machine for cleaning. Traditional installation methods are not only complicated to clean, but also have poor safety. Utility Model Content

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0041] like Figures 1 to 5 As shown;

[0042] An embodiment of the present invention provides a steam turbine boiler observation device, comprising:

[0043] The observation tube 1 is the core component of the entire device. It is located at the observation port of the steam turbine boiler. The end of the observation tube 1 is equipped with a connector 2.

[0044] Mounting bracket 3 is provided with a fixing member 4. The fixing member 4 is rotatably installed with the connecting member 2 through the connecting mechanism 5. Mounting bracket 3 is provided with an extension member 6. The extension member 6 is plugged into the slot at the end of the observation tube 1.

[0045] Camera 7 is installed in the mounting slot of mounting bracket 3 and is used to capture real-time images of the inside of the steam turbine boiler.

[0046] The movable handle 8 is fixedly installed on the mounting bracket 3 and is used to manually adjust the position of the mounting bracket, making it convenient for the camera 7's viewing lens to be cleaned.

[0047] The protection mechanism 9 is installed on the observation tube 1. The protection mechanism 9 is used to isolate the camera 7 from the steam turbine boiler when the camera is not in the observation state to prevent lens contamination.

[0048] By adopting the above technical solution, the observation tube 1, as the core component, is set at the observation hole of the boiler. The connector 2 at its end is rotatably connected to the fixing part 4 of the mounting bracket 3 through the connecting mechanism 5. With the extension part 6 being plugged and unplugged into the slot of the observation tube 1, the mounting bracket 3 and the camera 7 are flexibly positioned and stably installed, ensuring that the camera 7 can accurately capture real-time images inside the boiler. The movable handle 8 facilitates manual adjustment of the position of the mounting bracket 3 and makes it convenient to clean the observation lens of the camera 7, ensuring the clarity of observation. The protection mechanism 9 isolates the camera 7 from the boiler when not in the observation state, which can effectively prevent the lens from being contaminated and damaged by dust and high-temperature gases inside the boiler, extending the service life of the equipment. It also provides safety protection for operators when the camera 7 is being cleaned, improves the real-time performance and reliability of observation, reduces the risk of misjudgment due to unclear observation, and provides a strong guarantee for the safe and stable operation of the steam turbine boiler.

[0049] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the connecting mechanism 5 includes:

[0050] The connecting shaft 51 is rotatably installed in the through hole of the fixing part 4, and the connecting shaft 51 is slidably connected with the inner hole of the connecting part 2.

[0051] The baffle 52 is fixedly installed on the connecting shaft 51, and the baffle 52 is slidably connected to the inner groove of the connecting member 2;

[0052] Spring 53 has its two ends connected to the inner groove wall of the baffle 52 and the connector 2, respectively;

[0053] A drive rod 54 is provided on the connecting shaft 51. The drive rod 54 is used to drive the connecting shaft 51 to rotate. When the extension 6 is fastened to the observation tube 1, the drive rod 54 cooperates with the connecting piece 2 to lock. The connecting piece 2 is provided with a groove and a chamfer is provided at the groove. When the mounting bracket 3 and the observation tube 1 are displaced, the drive rod 54 slides in the groove.

[0054] In this embodiment, the connecting shaft 51 is rotatably installed in the through hole of the fixing member 4 and slides with the inner hole of the connecting member 2, which increases the rotational stability of the mounting frame 3. The sliding of the baffle 52 in the inner groove of the connecting member 2 further increases the relative movement stability. The spring 53 provides a pre-tightening force for the mounting frame 3 and the observation tube 1 to fasten, which facilitates the cleaning of the camera 7. The drive rod 54 can drive the connecting shaft 51 to rotate. When the extension 6 and the observation tube 1 are fastened, it cooperates with the connecting member 2 to lock, ensuring that the position of the mounting frame 3 is stable during observation. The chamfer design of the groove of the connecting member 2 allows the drive rod 54 to slide smoothly when the mounting frame 3 and the observation tube 1 are displaced, enhancing the ease of operation of the device.

[0055] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, protection mechanism 9 includes:

[0056] The protective plate 91 is slidably installed inside the through groove of the observation tube 1. A sealing element 92 is installed at one side of the through groove of the observation tube 1. The protective plate 91 and the groove of the sealing element 92 are plugged and pulled together.

[0057] The guide 93 is installed at the other end of the through groove of the observation tube 1, and the protective plate 91 is slidably connected to the groove cavity of the guide 93;

[0058] The drive mechanism 94 is mounted on the guide member 93 and is used to adjust the connection position between the protective plate 91 and the observation tube 1.

[0059] The adapter 95 is connected to the drive mechanism 94 and the observation tube 1 respectively;

[0060] In this embodiment, the protective plate 91 is slidably installed in the through groove of the observation tube 1. When not in the observation state, it can close the channel. It is plugged into the groove of the sealing member 92 at the through groove on one side of the observation tube 1, which can enhance the isolation and sealing performance and effectively prevent dust and high-temperature gas in the boiler from entering to protect the lens. The guide member 93 provides stable guidance for the sliding of the protective plate 91, ensuring its precise and smooth displacement. The drive mechanism 94 is installed on the guide member 93, which can conveniently adjust the connection position between the protective plate 91 and the observation tube 1 to realize the rapid switching between isolation and observation states. It can not only ensure the isolation and protection effect when not in observation, but also meet the observation needs through flexible adjustment, extend the service life of the camera 7, and enhance the safety of the device.

[0061] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the drive mechanism 94 includes:

[0062] Piston tube 94a is mounted on guide member 93, and extension tube 94b is provided at the slot of piston tube 94a;

[0063] Piston plate 94c is slidably installed inside the cavity of piston tube 94a. Piston rod 94d is provided on piston plate 94c, and the other end of piston rod 94d is installed on protective plate 91.

[0064] In this embodiment, the piston tube 94a is mounted on the guide member 93, and the extension tube 94b at its slot can introduce or extract gas. When the protective plate 91 needs to block, cold air is blown into the piston tube 94a through the extension tube 94b, pushing the piston plate 94c to slide in the cavity. Then, the piston rod 94d drives the protective plate 91 to move to the blocking position, realizing the isolation between the camera 7 and the boiler. When the protective plate 91 is opened to meet the observation needs of the camera 7, the gas inside the piston tube 94a is extracted through the extension tube 94b, and the piston plate 94c drives the piston rod 94d and the protective plate 91 to reset. The operation is convenient and the driving force is stable, which enhances the protective effect of the protection mechanism 9.

[0065] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the adapter 95 includes:

[0066] The first one-way exhaust valve 95a is installed on the piston tube 94a;

[0067] The first one-way air intake valve 95b is installed on the observation tube 1;

[0068] The air pipe 95c is connected at both ends to the first one-way air outlet valve 95a and the first one-way air inlet valve 95b, respectively.

[0069] The second one-way vent valve 95d is installed on the observation tube 1;

[0070] The first one-way inlet valve 95b and the second one-way outlet valve 95d are both located in the middle of the protective plate 91 and the mounting bracket 3. The first one-way inlet valve 95b and the second one-way outlet valve 95d are located at opposite ends, and the first one-way outlet valve 95a is connected to the piston tube 94a after the protective plate 91 is sealed.

[0071] In this embodiment, when the protective plate 91 blocks the view, the first one-way exhaust valve 95a opens and connects to the piston tube 94a, allowing the cold air in the piston tube 94a to enter the observation tube 1 area between the protective plate 91 and the mounting bracket 3 via the air pipe 95c and the first one-way intake valve 95b. The cold air cools the area, preventing the high temperature of the boiler from affecting the observation lens of the camera 7. The first one-way intake valve 95b and the second one-way exhaust valve 95d are located between the protective plate 91 and the mounting bracket 3 and are far apart, forming a convection channel. After the cold air enters, it can be discharged through the second one-way exhaust valve 95d to improve the cooling efficiency. The one-way valve design ensures directional airflow and prevents hot air backflow, which not only protects the equipment from high temperature damage but also maintains the stability of the observation area environment, enhancing the applicability of the device under high temperature conditions.

[0072] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, a flange is provided at the connection between the observation tube 1 and the steam turbine boiler, and an assembly hole is provided on the flange;

[0073] In this embodiment, the flange and assembly hole design at the connection between the observation tube 1 and the steam turbine boiler can achieve a stable and sealed connection between the two. By using the assembly hole and fasteners, the observation tube 1 can be accurately fixed at the observation hole of the boiler, ensuring the connection strength at the installation position. The flange connection enhances the sealing of the connection and effectively prevents high-temperature gas and dust from escaping from the boiler.

[0074] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
