Description

Technical Field

[0001] The present disclosure relates to a warning device, and in particular, to a warning device. Background Art

[0002] To eliminate potential safety hazards during defect elimination work in power plants, improve power plant safety management, and prevent personnel and equipment injuries caused by the inadvertent activation of safety measures during defect elimination, safety warning devices such as "Do Not Operate" and "Work Here" are typically displayed on system isolation valves according to work management requirements. However, in practice, multiple defect elimination tasks often share the same safety measure. For example, if defect elimination work on equipment A requires closing the manual inlet door of equipment A, and defect elimination work on equipment B also requires closing the manual inlet door of equipment A, two "Do Not Operate" warning devices must be displayed on the manual inlet door of equipment A simultaneously. During this period, if defect elimination work on equipment A is completed and the safety measure of closing the manual inlet door of equipment A is no longer required, one "Do Not Operate" warning device is retracted, and when defect elimination work on equipment B is completed, the other "Do Not Operate" warning device is retracted to close the defect elimination loop. Especially during unit-level maintenance, some isolation valves require the installation of three or more warning devices simultaneously. For valves with limited operating space, the installation of multiple warning devices is simply not feasible. Utility Model Content

[0021] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0022] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to the inside and outside relative to the outline of a component or structure. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0023] like Figure 1 As shown, the present disclosure provides a warning device, including: a device body 1, on which a warning sign 2 is provided; and a numbering device 3, including a digital block 32 that can display and edit numbers. The numbering device 3 is set on the device body 1 and the digital block 32 is at least partially set on the outer surface of the device body 1.

[0024] Through the above technical solution, the device body 1 is installed in a place where warning is required, and the warning sign 2 displays a warning slogan or warning pattern, such as no operation, work here, etc. When multiple troubleshooting personnel share a safety measure, there is no need to hang multiple warning signs. It is only necessary to edit the numbers on the digital block 32 so that the numbers correspond to the number of warning signs. This solves the problem of insufficient space caused by setting up multiple warning signs for one safety measure. At the same time, it is easy and quick to use, which improves work efficiency. The troubleshooting personnel do not need to carry warning signs when working, which makes work convenient and also avoids the loss of warning signs.

[0025] As an optional implementation, Figure 1-2 As shown, the digital block 32 is configured as a movable digital wheel, and the displayed digits are edited by moving the digital wheel. Of course, in other embodiments, the digital block 32 may also be a display screen.

[0026] Alternatively, as Figure 2 As shown, the numbering device 3 also includes a shell 31, a rotating shaft 33 and a limiter 34. The shell 31 is arranged on the device body 1 and one side of which is flush with the outer surface of the device body 1. A through hole 311 is provided on this side. The rotating shaft 33 is arranged in the shell 31. There is at least one digital wheel and it is rotatably connected to the rotating shaft 33. The digital wheel partially extends out of the shell 31 through the through hole 311 to facilitate operation by the staff. The limiter 34 is arranged in the shell 31 and contacts the digital wheel to limit the digital wheel. The side of the shell 31 that is flush with the outer surface of the device body 1 is the display side and the operation side, which is used for the staff to operate the digital wheel. The rotating shaft 33 is arranged in the shell 31, and the digital wheel is rotatably connected to the rotating shaft 33. When the number needs to be edited, the digital wheel is rotated to change the number displayed by the digital wheel. After the number is edited, the limiter 34 limits the digital wheel to prevent the digital wheel from rotating due to accidental touch and causing errors.

[0027] Alternatively, as Figure 2 As shown, the limiting member 34 includes a stop plate 341. The outer contour of the digital wheel is provided with a plurality of stop surfaces 321 arranged along the outer tangent line of the digital wheel. The stop plate 341 is arranged in the shell 31 and is in contact with one of the stop surfaces 321. For example, the stop plate 341 is vertically arranged on the side opposite to the side of the shell 31 where the through hole 311 is provided. The stop surface 321 is a plane and is in contact with the stop plate 341 to limit the digital wheel. Different numbers are respectively provided on each stop surface 321, for example, 0-9. Each stop surface 321 is provided with a number, and the numbers increase sequentially along one direction.

[0028] The stop plate 341 is constructed as an elastic plate. Since the stop surface 321 has sharp edges, when the digital wheel is rotated, the sharp edges push the stop plate 341 to bend away from the digital wheel. When the stop surface 321 is rotated to be parallel to the stop plate 341, the stop plate 341 is attached to the stop surface 321 to limit the digital wheel. For example, the stop plate 341 is a metal plate.

[0029] Alternatively, as Figure 2 As shown, the limiting member 34 also includes a connecting piece 342 and a stop block 343. A groove 322 is provided between two adjacent stop surfaces 321. The connecting piece 342 is constructed as an arc structure corresponding to the outer contour of the digital wheel. One end of the connecting piece 342 is connected to the stop plate 341, and the other end extends along the outer contour of the digital wheel and is connected to the stop block 343. The stop block 343 is constructed as a triangular structure. Because the triangular structure has an inclined surface, the two sides of the groove 322 can be set as inclined surfaces. This makes it easier to rotate the digital wheel and prevents the digital wheel from getting stuck. The stop block 343 is engaged with the groove 322. When the stop plate 341 is in contact with the stop surface 321, the stop block 343 is engaged in the groove 322, further limiting the digital wheel.

[0030] The connecting piece 342 is constructed as an elastic piece. When the digital wheel is rotated, the stop surface 321 pushes the stop block 343 to move. The stop block 343 drives the connecting piece 342 to bend in the direction away from the digital wheel. The stop block 343 disengages from the groove 322, allowing the digital wheel to rotate. After the rotation is completed, the stop block 343 is re-engaged in the groove 322. For example, the connecting piece 342 is a metal piece.

[0031] As an optional implementation, Figure 1 As shown, the device body 1 is constructed as a corrosion-resistant warning sign. Because the environment in a factory or power plant is relatively complex, in order to extend the service life of the device body 1, the device body 1 is set to a corrosion-resistant structure, for example, the device body 1 is constructed as a stainless steel plate.

[0032] As an optional embodiment, a reflective layer is provided on the outer side of the warning sign 2, which can reflect light at night, making it easier for staff to see it.

[0033] As an optional embodiment, the warning device is used to be installed at the safety valve of the power plant. Because when the power plant is carrying out troubleshooting work, it is often the case that multiple groups of workers share the same valve. The installation of the warning device disclosed in the present invention eliminates the need to hang multiple warning signs, is easy to use, and does not cause the problem of insufficient space.

[0034] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0035] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
