Description

Technical Field

[0001] This utility model relates to the field of safety warning equipment technology, and is a safety sign. Background Technology

[0002] In power plants and industrial automation facilities, scenarios with multiple control panels or multiple pieces of equipment arranged side-by-side are extremely common. When some or all equipment enters the maintenance process, to effectively prevent maintenance personnel from accidentally entering live areas and to prevent personal injury or equipment damage caused by improper operation, using safety signs to clearly distinguish the control panels from adjacent operating panels has become one of the core measures to ensure safe production. As a key visual tool for on-site safety protection, the accurate and stable status display of safety signs directly affects the operators' ability to quickly identify and judge the operating status of equipment, playing an irreplaceable role in maintaining the safe and stable operation of the plant.

[0003] However, the safety signs currently widely used in plants have significant shortcomings in terms of technical implementation and usage management. From a functional design perspective, existing signs mostly adopt a fixed, single-content display structure, which cannot adapt to the dynamic changes in equipment status. When the status of a control panel changes between operation and maintenance, operators must strictly follow a complex operating procedure: when a running control panel is switched to maintenance, a new "Work Here" sign must be installed on the control panel, and a "Operation" sign must be added to the adjacent control panel; when a control panel is put into operation and an adjacent control panel is switched to maintenance, the "Work Here" sign on the control panel to be put into operation is replaced with a "Operation" sign, and the adjacent control panel switched to maintenance has its "Operation" sign replaced with a "Work Here" sign; when a control panel is put into operation after maintenance and the adjacent control panel is not switched to maintenance, the "Work Here" sign on the control panel to be put into operation is removed, and the "Operation" sign on the adjacent control panel is also removed. This series of cumbersome operations not only significantly increases labor and time costs, but also makes it extremely easy for signs to be misinstalled or omitted due to operational oversights, thus creating serious safety hazards. In terms of structural design, the drawbacks of traditional signs using ropes for fixation are becoming increasingly apparent. In actual operation scenarios, frequent retrieval and installation cause the ropes to easily become knotted and tangled. In areas with densely packed multi-panel cabinets, rope detachment is a frequent problem, seriously affecting the stability and reliability of the signs. At the same time, due to the lack of standardized installation specifications, different operators have varying degrees of understanding of the installation position and angle of the signs, resulting in a chaotic and disorganized arrangement of signs on site. This reduces the overall aesthetics and weakens the efficiency of workers in quickly identifying the information. In terms of usage and management, existing signs, due to their large quantity and heavy material, require a lot of physical effort to retrieve and are prone to chaotic stacking when stored, posing significant challenges to inventory management and maintenance. The mixing and misuse of signs occur frequently, making it difficult to meet the stringent requirements of modern plant operations for efficient and accurate equipment safety management.

[0004] With the rapid development of smart grids and industrial automation, the contradiction between the technical limitations of traditional safety signs and the safety production needs of plants and stations is becoming increasingly prominent. There is an urgent need to develop new types of safety signs through technological innovation and structural optimization in order to improve the safety management level of plants and stations and ensure the safety of personnel and equipment.

[0030] Example 1:

[0031] See attached Figures 1-7A safety sign includes a housing 1, a display mechanism, and a drive mechanism. The display mechanism and drive mechanism are housed within the housing 1, which serves as a supporting structure, protecting them from external influences. A fixing structure is located on the outer side of the back of the housing 1, used to install the safety sign at the desired location for worker use. The fixing structure can employ screws, magnetic attachment, adhesive, clips, or hooks, and various combinations of these methods can be used to ensure the safety sign remains stable and does not shift during long-term use. A display window 2 is located on the front side of the housing 1 to display the display interface 3 of the display mechanism. The display mechanism has multiple different display interfaces 3, and three interfaces 3 can be set to indicate three different operating conditions of the cabinet (equipment): "Operating," "Working Here," or the color of the cabinet (equipment). The drive mechanism drives the display mechanism to rotate, causing the display interface 3 corresponding to the current operating status of the control panel to rotate to the display window 2 on the outer casing 1. Workers can then see the current operating status of the control panel through the display window 2. This utility model's safety sign allows workers to quickly switch between warning messages, meeting the warning needs of various operating conditions such as control panel maintenance and operation. It is easy to operate, reduces workload, and improves work efficiency. Furthermore, the sign can be permanently installed on the control panel as needed.

[0032] Specifically, the display mechanism comprises several triangular prism components, as shown in the attached diagram. Figure 1 As shown, a set of vertically parallel support plates 5 are provided inside the outer casing 1. Five triangular prism 6 assemblies 4 can be arranged between the two support plates 5, and the five triangular prism 6 assemblies 4 are arranged horizontally and closely together. Each triangular prism 6 assembly 4 includes a triangular prism 6 and a rotating shaft 7. The triangular prism 6 is fixedly sleeved on the rotating shaft 7, so that the long side edges of the five triangular prisms 6 are close together in pairs. The two ends of the rotating shaft 7 are rotatably mounted on the upper and lower support plates 5 respectively. To reduce friction between the support plates 5 and the rotating shaft 7, bearing holes 8 are provided on the support plates 5 corresponding to the positions of the rotating shaft 7. Bearings are installed on the side walls of the bearing holes 8, and the end of the rotating shaft 7 is fixed to the inner ring of the corresponding bearing. Different display interfaces 3 are provided on the three sides of the triangular prisms 6, that is, the display interface 3 for the same working condition is divided into five parts, and the five parts are respectively set on the sides corresponding to the five triangular prisms 6. It can be understood that the display interface 3 for the same working condition is composed of the sides of the five triangular prisms 6. When initially installing the triangular prisms 6, ensure that the display interface 3 for the same working condition formed by the sides of the five triangular prisms 6 is on the same plane. When the staff needs to use a safety sign to indicate the current working condition of the corresponding panel, when the rotating shaft 7 is turned, the five triangular prisms 6 will rotate simultaneously, so that the display interface 3 corresponding to the same working condition can be rotated to the display window 2 and parallel to the display window 2.

[0033] Specifically, the drive mechanism includes a rack 9 and a first sliding block 12, and a horizontal slide rail 10 is provided on the inner wall of the housing 1, as shown in the attached figure. Figure 1 As shown, the horizontal slide rail 10 can be positioned above the upper support plate 5 and fixed to the rear side of the outer casing 1. A slidable rack 9 is provided on the horizontal slide rail 10. The rack 9 is vertically positioned, and a long, narrow groove 25 can be provided on the back of the rack 9, as shown in the attached diagram. Figure 5 As shown, the groove 25 engages with the horizontal slide rail 10. The end of the rotating shaft 7 corresponding to the rack 9 passes through and extends beyond the upper support plate 5. A gear 11 meshes with the rack 9 on the outer wall of the end of the rotating shaft 7 extending beyond the support plate 5. The rack 9 slides on the horizontal slide rail 10, causing the rotating shaft 7 to rotate. A first sliding block 12 is located at the top of the rack 9. A first toggle key 13 is located on the front side of the first sliding block 12. A first elongated hole 14 is located on the front wall of the outer casing 1 at a position corresponding to the first toggle key 13. The first elongated hole 14 is horizontally positioned, and one end of the first toggle key 13 extends through the first elongated hole 14 and is located outside the outer casing 1. When the operator moves the first toggle key 13 along the first elongated hole 14 outside the outer casing 1, the first sliding block 12 causes the rack 9 to slide on the horizontal slide rail 10, thereby causing the rotating shaft 7 to rotate.

[0034] Specifically, the safety sign of this utility model also includes a locking mechanism, which includes a second sliding block 15 located above the first sliding block 12. The top of the first sliding block 12 has several locking protrusions 17, and the bottom of the second sliding block 15 has a locking groove 16. The locking protrusions 17 cooperate with the locking groove 16. When the locking protrusions 17 are inserted into the locking groove 16, the first sliding block 12 is locked. It is understood that the size of the locking groove 16 should be able to accommodate the locking protrusions 17, and the distance between the locking protrusions 17 should be greater than the distance from the side wall of the locking groove 16 to the side wall of the second sliding block 15. A groove 18 is provided on the inner side wall of the outer casing 1, which can be set on the rear side wall of the outer casing 1 corresponding to the second sliding block 15, as shown in the attached figure. Figure 1 As shown, vertical slide rails 19 are provided on both side walls of the slide groove 18. A long, narrow groove 25 can be provided on the side of the second sliding block 15 facing the slide groove 18, corresponding to the vertical slide rail 19, as shown in the attached diagram. Figure 7As shown, the groove 25 cooperates with the vertical slide rail 19, allowing the second sliding block 15 to slide up and down along the vertical slide rail 19, causing the second sliding block 15 to move closer to or away from the first sliding block 12. A limiting block 20 is also provided on the side of the second sliding block 15 facing the slide groove 18. When the second sliding block 15 is engaged with the vertical slide rail 19, the limiting block 20 is located inside the slide groove 18. A limiting rod 21 is provided on the limiting block 20, and a spring 22 is sleeved on the limiting rod 21. One end of the spring 22 is fixed to the top plate of the slide groove 18, and the other end is fixed to the limiting block 20. The spring 22 is used to generate the tendency for the second sliding block 15 to move towards the first sliding block 12. When the locking groove 16 of the second sliding block 15 locks the locking protrusion 17 of the first sliding block 12, the spring 22 is also in a compressed state. The spring 22 keeps the locking groove 16 engaged with the locking protrusion 17. When the lock needs to be engaged, a larger force is applied to overcome the force of the spring 22 and slide the second sliding block 15 upward, causing the locking groove 16 to disengage from the locking protrusion 17. A second toggle key 23 is provided on the side of the second sliding block 15 facing the display window 2. A second elongated hole 24 is provided on the outer casing 1 at a position corresponding to the second toggle key 23. The second elongated hole 24 is located above the first elongated hole 14 and is perpendicular to the first elongated hole 14. One end of the second toggle key 23 protrudes through the second elongated hole 24 and is located on the outside of the outer casing 1 for easy operation by the operator. When staff need to switch the warning content of the safety sign, they slide the second toggle key 23 upward along the second elongated hole 24, unlocking the first sliding block 12 and the second sliding block 15. Then, they slide the first toggle key 13 along the first elongated hole 14, rotating the triangular prism 6 to rotate the display interface 3 corresponding to the cabinet's operating condition to the display window 2. During the sliding of the first toggle key 13, the second toggle key 23 is always under external force. After the display window 2 displays the current cabinet operating condition, the external force on the second toggle key 23 is removed, and the second sliding block 15 moves downward under the action of the spring 22. Finally, the locking groove 16 cooperates with the locking protrusion 17 to lock the first sliding block 12, ensuring that the display interface 3 displayed in the display window 2 remains stable and reliable, preventing the triangular prism 6 from rotating due to external influences, which would cause the display window 2 to display inaccurately.
