Abstract
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 the operation and maintenance of power systems, the correct implementation of safety measures plays a crucial role in ensuring the safety of personnel and the stable operation of equipment. Among these measures, the hanging of safety signs, as a direct and effective safety isolation method, is widely used in various power work scenarios. Safety signs serve as reminders, warnings, and guidance, directing equipment maintenance work to be carried out accurately and safely. They can prevent incidents such as accidentally entering energized areas or misoperating live equipment, ensuring workplace safety and the smooth operation of work processes, and contributing to maintaining workplace safety and improving work efficiency.
[0003] Currently, the widely adopted signage management and usage methods in the industry have significant drawbacks, mainly in the following aspects: First, the storage and management costs of signs are high. Since "Do Not Close, People Working" and "Do Not Operate, People Working" signs need to correspond to different equipment (power switches and valves), existing methods require separate storage of these two types of signs in separate zones, and a reserve of signs matching the number of equipment on site is required. This not only increases storage space usage but also raises the complexity of daily management, easily leading to problems such as sign confusion, loss, or insufficient inventory. Second, the convenience and safety for operators during operation are insufficient. During on-site operation, operators need to carry two types of signs corresponding to the number of equipment being operated, according to the work order requirements. Due to the large number of signs, carrying them can easily affect operational efficiency due to their large size or scattered placement, and they may even be lost on site, creating safety hazards. If a sufficient number of signs are not carried before operation, continuing operation will face the risk of misoperation, while pausing operation to replenish signs will significantly reduce work efficiency and affect the overall progress of maintenance work. Third, the risk of incorrectly placed signs threatens personal and equipment safety. Because the text on the two types of signs is similar and the only difference is the target audience, operators are prone to hanging the signs for power switches and valves backwards when operating under high intensity or when their attention is not focused. This can lead to maintenance personnel misunderstanding the equipment status, potentially causing misoperation and resulting in serious consequences such as personal injury or equipment damage.
[0004] In summary, the existing management and use of "Do Not Close the Switch, People Are Working" and "Do Not Operate, People Are Working" signs have obvious deficiencies in terms of storage management, ease of operation, and safety and reliability. There is an urgent need to improve the existing safety signs to meet the safety and efficiency requirements of equipment maintenance operations in the industrial field. Utility Model Content

[0027] Example 1:
[0028] See attached Figures 1-5 A safety sign includes a display panel 1, a support frame 2, a fastening mechanism 3, and a fixing mechanism 4. The support frame 2 serves as the supporting structure for the entire system. It can be configured as a rectangular frame surrounded by four borders. Grooves are provided on the inner walls of each of the four borders of the support frame 2, and these four grooves are interconnected. An elongated hole 5, communicating with the corresponding groove, is provided on the right side border of the support frame 2. (See attached image.) Figure 1 and attached Figure 2As shown, the elongated hole 5 can also be opened on the left side, allowing the display panel 1 to be initially fixed by inserting it into the groove on the inner wall of the support frame 2 through the elongated hole 5. A fastening mechanism 3 is provided on the support frame 2, which further fixes the display panel 1 into the groove on the inner wall of the support frame 2. A fixing mechanism 4 is also provided on the support frame 2, which allows the safety sign of this utility model to be hung on the switch or valve body or fixed to the panel cabinet surface. The display panel 1 of this utility model has different display surfaces on its front and back. For example, the front display surface can be set to display "Do not close, people are working," and the back display surface can be set to display "Do not operate, people are working." Furthermore, a base plate 6 is provided inside the support frame 2. The four sides of the base plate 6 are fixed to one side wall of the corresponding groove. The base plate 6 is a thin plate, so the groove can also accommodate the corresponding four sides of the display panel 1. One side of the base plate 6 has a display surface set to display "Equipment in operation." When the operating conditions of the equipment change and the safety sign needs to be updated to reflect the current operating conditions, simply insert the display panel 1 through the elongated hole 5 into the groove on the inner wall of the support frame 2, ensuring the corresponding display surface faces the operator. Then, using the fixing mechanism 4, the safety sign is suspended on the switch or valve body or fixed to the panel cabinet surface, providing reminders, warnings, and guidance to the operator. This invention discloses a safety sign that serves three purposes in one, reducing the number of signs carried, improving operational efficiency, facilitating on-site management, and featuring a simple structure. It guides equipment maintenance and repair work accurately and safely, preventing incidents such as accidental entry into energized areas or misoperation of energized equipment, thus ensuring workplace safety and smooth workflow, and contributing to workplace safety and improved work efficiency.
[0029] Specifically, the fastening mechanism 3 of this utility model can adopt an elastic pressing structure like that of a ballpoint pen, including a pressing push rod 7, a guide member 8, a sliding member 9, a pressing rod 10, and a first spring 11. (See attached diagram) Figure 4As shown, a through hole is provided on the top frame of the support frame 2. A guide member 8 is provided on the inner wall of the upper part of the through hole. A guide groove is provided circumferentially on the upper part of the inner side wall of the guide member 8. A deep groove and a shallow groove are provided circumferentially on the bottom. The grooves of different depths are arranged adjacent to each other circumferentially, and the bottom edge is a bevel facing into the groove. The bevels are all in the same direction. The top of the pressing push rod 7 is located outside the through hole for easy pressing by the operator. The bottom is located inside the through hole and is serrated. A guide block that mates with the guide groove is provided on the side wall. A protrusion that mates with the groove is provided on the outer side wall of the sliding member 9. The top of the protrusion is a bevel that meshes with the serrated part at the bottom of the pressing push rod 7. A pressing rod 10 is connected to the bottom of the sliding member 9. A limiting edge is provided at the bottom of the through hole. A first spring 11 is sleeved on the outside of the pressing rod 10. The first spring 11 is located between the limiting edge and the sliding member 9. After the display panel 1 is inserted into the groove on the inner wall of the support frame 2, the push rod 7 is pressed down, pushing the compression rod 10 through the through hole and abutting against the display panel 1 to further fix the display panel 1. When it is necessary to remove or replace the display panel 1, the push rod 7 is pressed down again, and under the action of the first spring 11, the compression rod 10 retracts into the through hole. It can be understood that the fastening mechanism 3 can also be a threaded rod. A threaded hole is provided on the top frame of the support frame 2. After the display panel 1 is inserted into the groove on the inner wall of the support frame 2, the threaded rod is screwed into the threaded hole until the threaded rod abuts against the display panel 1, further fixing the display panel 1 in the groove on the inner wall of the support frame 2 and preventing the display panel 1 from slipping off the side of the support frame 2.
[0030] Specifically, the fixing mechanism 4 includes an elastic rope 12 and a rope tightening assembly 13. The rope tightening assembly 13 includes a connector 14, a second spring 15, and two pressing members 16. (See attached diagram) Figure 5As shown, the connector 14 has a transverse through hole, and pressing members 16 are provided on both sides of the through hole. The pressing members 16 on both sides are connected by a second spring 15. Part of the pressing member 16 is located inside the through hole, and part of it is located outside the through hole. There are also vertically penetrating limiting holes on both sides of the connector 14. There are also vertically penetrating limiting holes on the two pressing members 16 at the positions corresponding to the limiting holes of the connector 14. Pressing the pressing members 16 on both sides connects the pressing members 16 with the corresponding limiting holes of the connector 14. One end of the elastic rope 12 is fixed to the top frame of the support frame 2, and the other end passes through one side of the connector 14 and the limiting hole on the corresponding pressing member 16, then through the other side of the connector 14 and the limiting hole on the corresponding pressing member 16, and finally is fixed to the top frame of the support frame 2. The operator can press the pressing part 16 to connect the corresponding limiting holes of the pressing part 16 and the connecting part 14, and pull the elastic rope 12 to adjust the length of the elastic rope 12 required for suspension. Then, the safety sign of this utility model can be suspended on the operating handle of the power switch or valve through the elastic rope 12. The fixing mechanism 4 also includes a suction cup 17, which is fixedly connected to the connecting part 14. When the equipment is a panel cabinet, the safety sign of this utility model can be fixed to the panel cabinet by the suction cup 17.
[0031] Specifically, the safety sign of this utility model also includes a locator 18, which is mounted on the suction cup 17. The locator 18 is a tag locator 18. The tag locator 18 is a device with anti-loss and electronic fence functions, used to track and locate items or personnel. It is typically small in size and easy to attach to the tracked object. It connects to mobile phones or other terminal devices through various communication technologies to achieve target location monitoring. Using the tag locator 18 on the suction cup 17, the safety sign can be accurately positioned: preventing the loss of on-site signs; the tag locator 18 can quickly locate the corresponding secondary power switch or mechanical valve, allowing for rapid familiarization with the location of on-site equipment; the tag locator 18 corresponds to the equipment name, allowing for the determination of the number of on-site signs, enabling verification of any omissions in operations and improving the accuracy of operation tickets; it also functions as an electronic fence, allowing for the setting of alarms within a certain distance to avoid misoperation and remind maintenance personnel of their personal safety.
