[0002] As vital energy suppliers for the nation, power plants operate under complex conditions involving high temperatures, high pressures, and high currents. To ensure the safe and stable operation of the power generation system, various equipment within the power plant, such as steam turbines, generators, high-voltage switchgear, and transformers, require regular maintenance, inspection, and repair. Especially during load fluctuations or equipment malfunctions, unplanned emergency maintenance operations are necessary. These maintenance activities typically occur at the equipment operating site, in highly hazardous environments, where even slight negligence can lead to electric shock, mechanical injuries, or major safety accidents. Therefore, implementing effective personnel isolation and work area protection during maintenance operations is a crucial aspect of power plant safety management.

[0003] Currently, in power plant equipment maintenance, methods such as setting up warning signs, erecting warning lines, and using folding fences are commonly used to isolate work areas. However, these traditional measures have certain limitations: warning lines, warning signs, or fixed fences often lack flexibility and adaptability. Traditional warning facilities cannot provide timely responses when personnel enter or exit, and the fixed installation of warning signs and fences is not adapted to changes in different work scenarios, resulting in insufficient visibility and warning effectiveness in some environments. In addition, existing safety protection devices usually lack automation and intelligent functions, lacking real-time sensing and alarm mechanisms when personnel approach dangerous areas, resulting in slow response times for safety management and increasing potential safety hazards.

[0004] To address the above issues, a power plant production safety management and protection device is proposed. Utility Model Content

[0030] 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.

[0031] Reference Figure 1 - Figure 2This utility model provides an embodiment of a power plant production safety management and protection device, comprising a base 1, with casters 2 at each of the four corners of the base 1, giving the device high flexibility and allowing for easy movement between different locations within the power plant. A handle 11 is located on one side of the top of the base 1, allowing users to easily push and guide the device's movement, ensuring safety and stability during movement. A control box 6 is located on the other side of the top of the base 1, housing a speaker to provide audible alerts during device operation, enhancing the warning effect. Other electronic control modules can also be installed in the control box 6 to achieve intelligent control of the device. To further improve the safety of the work site, two infrared sensors 7 are symmetrically arranged at the front end of the base 1. These infrared sensors 7 can detect personnel approaching the construction area. When personnel enter a pre-set danger zone, the infrared sensors 7 immediately activate, triggering the speaker to emit a warning sound and issuing an alarm signal through the control box 6, prompting personnel to promptly move away from the danger zone. To provide better isolation, a foldable isolation barrier 3 is installed on the top of the base 1. Its foldable design allows it to be freely unfolded or folded up as needed, greatly improving the convenience and adaptability of the device. Main horizontal bars 32 are installed on both the top and bottom sides of the foldable isolation barrier 3. Extension bars 33 are inserted into both ends of the main horizontal bars 32. These extension bars 33 can be quickly unfolded when needed to expand the isolation area and ensure a safe distance between workers and other personnel. A warning sign 4 is installed on the front of the foldable isolation barrier 3. The warning sign 4 is used to warn of the danger in the work area. Its installation position and material are carefully designed to ensure clear visibility and stable operation even in high-temperature and windy environments. In addition, main vertical bars 31 are installed on both the left and right sides of the foldable isolation barrier 3. Each main vertical bar 31 contains an extension component 5. This extension component 5 is adjusted via a control lever 51 to allow for rapid deployment and adjustment of the isolation range.

[0032] Reference Figure 1 and Figure 4The extension component 5 includes a control rod 51, which is slidably connected to the main crossbar 32 and the extension rod 33. To ensure stable support for the control rod 51 during sliding, a pressure spring 52 is fitted around the outside of the control rod 51. The pressure spring 52 provides appropriate elastic force to ensure smooth operation and pressure application during sliding. A limit plate 53 is fixedly connected to the middle of the control rod 51, which limits the movement of the control rod 51 and prevents it from deviating from the track or exceeding the preset range of motion during sliding. The control rod 51 is slidably connected inside the main vertical bar 31. To ensure smooth sliding, a groove is provided inside the main vertical bar 31. The groove effectively guides the control rod 51 along the set track. To ensure the rebound function of the control rod 51 during sliding, a pressure spring 52 is installed inside the groove. Its bottom is fixedly connected to the top of the limit plate 53, and its top is fixedly connected to the inner top wall of the groove, forming an elastic recovery structure. As the control lever 51 slides outward, the pressure provided by the compression spring 52 effectively pushes it inward, allowing the control lever 51 to stably return to its original position after adjustment. Overall, the design of this extension assembly 5 not only ensures the rapid and smooth extension and retraction of the barrier, but also effectively guarantees the long-term stability of the equipment through the rebound force provided by the compression spring 52, and enhances the ease of operation of the device.

[0033] Reference Figure 2 - Figure 3 The warning sign 4 has two symmetrical mounting slots 41 on its rear side. This design allows the warning sign 4 to be quickly installed and removed when needed, facilitating flexible use in different working environments. Two connecting rods 43 are fixedly connected to the outer side of the main crossbar 32. These connecting rods 43 connect the warning sign 4 to the main crossbar 32. The connecting rods 43 are fixedly connected to the main crossbar 32, ensuring that the warning sign 4 can be stably hung on the guardrail and is not easily detached. A slider 42 is fixedly connected to the end of the connecting rod 43 away from the main crossbar 32. The slider 42 slides into the mounting slots 41, ensuring that the warning sign 4 can be flexibly installed on the guardrail as needed. Furthermore, the sliding connection of the slider 42 also allows for easy replacement of different warning signs 4.

[0034] Working Principle: When the equipment needs to be installed in a specific work area within the power plant, the base 1 moves to the designated position via casters 2. A handle 11 on one side of the base 1 assists in pushing, while the control box 6 on the other side contains a speaker and control module; the speaker emits a warning sound. An infrared sensor 7 at the front of the base 1 triggers an alarm system when it detects personnel approaching. The foldable barrier 3 is connected and unfolded via a main crossbar 32 and an extension rod 33. Extension components 5 are located inside the main vertical bars 31 on both sides of the barrier. A control rod 51 slides within a sliding groove, and the extension rod 33 inserted into the main crossbar 32 is fixed in place by a pressure spring 52 and a limiting plate 53, allowing for quick and complete extension of the barrier. The warning sign 4 is connected to a slider 42 via a connecting rod 43. The slider 42 slides within a mounting groove 41, allowing the warning sign 4 to be quickly installed or replaced as needed. The control box 6 controls the operation of all components. When the infrared sensor 7 detects personnel entering the warning area, the control box 6 emits a warning sound via a speaker, ensuring the safety of the work area.
