Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary tools for electrical equipment maintenance, in particular to a shielding type warning sign. Background Art
[0002] Power plant maintenance and repair work is extensive and time-consuming, often accompanied by information asymmetry at the worksite. Failure to properly place signs can lead to personal injury and equipment damage due to misoperation. Currently, most signs are suspended, which often presents difficulties due to the lack of mounting points on the equipment. For example, when hanging a sign on the air switch assembly on an electrical box, there are two issues. First, there is no mounting area on the box, requiring the installation of a separate hook, which is inconvenient. Second, when the sign is hung, it is impossible to verify whether the air switch on the box is closed, requiring manual inspection, which can lead to missed detections. To address these two issues, a shielded warning sign has been designed.
[0003] After searching, Chinese patent document CN115719574B, published (announced) date: 2024.07.02, discloses a portable multifunctional infrared sensing voice alarm sign, including a mounting assembly, including a base plate, a binding member arranged on one side of the base plate, and a clamping member arranged at the bottom of the binding member; an anti-slip assembly, including a connecting member arranged at the bottom of the base plate, and a transmission member arranged between the connecting members; and a warning assembly, arranged on one side of the base plate. Its characteristics are: through the arrangement of the mounting assembly and the anti-slip assembly, the warning sign can avoid being blown off by the wind outdoors and can ensure that it will not fall off after being installed for a long time. In addition, the warning assembly can effectively serve as a warning to others; its shortcomings are: the infrared sensing voice alarm sign cannot be installed on an electrical box, and it cannot check whether the air switch is turned off.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0031] Example 1:
[0032] See Figure 1-6A shielding warning sign includes a sign body 10, and extensions 20 are respectively provided on the upper and lower sides of the back of the sign body 10. The distance between the upper and lower extensions 20 is not less than the width L of the protruding portion 52 of the air switch 50. The extension 20 is installed with an adsorption member 21 at the end away from the sign body 10. The back of the sign body 10 is also provided with a limiting portion for identifying the position of the operating handle 51 of the air switch 50. In use, when the operating handle 51 is in the disconnected position, each of the adsorption members 21 contacts the panel 41 of the electrical box 40. By respectively arranging extension pieces 20 on the upper and lower sides of the back of the sign body 10, the extension pieces 20 are used to block the air switch 50, and the extension piece 20 is installed with an adsorption piece 21 at the end away from the sign body, and the adsorption piece 21 adsorbs the panel 41 of the electrical box 40, thereby fixing the sign body 10, and a limiting portion is also provided on the back of the sign body 10. Only when the operating handles 51 of the air switch 50 are all in the closed position, can each adsorption piece 21 be stably contacted and adsorbed with the panel 41, so that when the shielding warning sign of this application is installed, it is possible to check whether the air switch 50 is closed.
[0033] Warning words are provided on the front of the sign body 10 . In this embodiment, the words “Do not close the switch, someone is working” are provided on the front of the sign body 10 .
[0034] See also Figure 1 、 4 In this embodiment, the extension member 20 is a multiple rod structure. The suction member 21 is a magnet or a suction cup. Furthermore, the extension member 20 of the rod structure can be integral with the sign body 10, or can be screwed to the sign body 10 using a screw portion 22, or can be adhesively fixed.
[0035] Specifically, when the adsorption member 21 is a magnet, in one of the solutions, see Figure 2 A blind hole is provided at the end of the adsorption member 21, and the magnet is fixedly installed in the blind hole by bonding or interference fit.
[0036] When the adsorption member 21 is a suction cup, in one embodiment, see Figure 3 A blind hole is provided at the end of the adsorption member 21, and the suction cup has a rod structure, which is fixedly installed in the blind hole by bonding or interference fit.
[0037] In this embodiment, see Figure 1-5 , the limiting portion is a protrusion 30. See further Figure 5The protrusion 30 is a concave arc structure that cooperates with the control switch 50. Only when the operating handle 51 is in the closed position will the operating handle 51 not interfere with the protrusion 30, so that the shielding warning sign of the present application can be stably installed.
[0038] Example 2:
[0039] The difference from the first embodiment is that in this embodiment, the extension member 20 is a plate structure, which is not shown in the figure. The extension member 20 of the plate structure can be an integral structure with the sign body 10, or can be bonded and fixed to the sign body 10.
[0040] Specifically, the installation method of the adsorption member 21 is the same as when the adsorption member 21 is a rod structure.
[0041] It should be noted that the distance between the upper and lower extension members 20 is generally slightly larger than the width L of the extension portion 52 of the air switch 50 , for example, the distance between the upper and lower extension members 20 is greater than L: 1-5 mm.
[0042] Example 3:
[0043] The difference from Example 1 is that, in this embodiment, see Figure 6 The limiting portion is the groove 31. Only when the operating handle 51 is in the closed position does the operating handle 51 not interfere with the back of the sign body 10, thereby ensuring the stable installation of the shielded warning sign of the present application. When the operating handle 51 is in the closed position, the operating handle 51 extends into the groove 31.
[0044] Example 4:
[0045] In this embodiment, the sign body 10 has a hollow cavity structure and is equipped with a battery compartment 11, a switch 12, and a human detection alarm 14. The battery compartment 11 is used to install batteries, which are electrically connected to the human detection alarm 14 via the switch 12. The human detection alarm 14 is connected to a speaker 13. The human detection alarm 14 can adopt the infrared sensor voice alarm disclosed in CN115719574B. In use, the switch 12 is turned on to connect the human detection alarm 14 to power. When a person approaches, the human detection alarm 14 detects the person and issues a voice alarm.
[0046] Furthermore, LED lights can also be installed on the sign body 10. For example, the warning text on the front side adopts LED luminous characters. When someone approaches, it will be detected by the human detection alarm 14 and the LED light will flash.
[0047] The working principle or action process of the utility model is as follows:
[0048] When in use, close the operating handle 51 of the air switch 50 in the electrical box 40, and adsorb the shielding warning sign of the present application onto the panel 41 of the electrical box 40. Depending on the material of the panel 41, when the panel 41 is made of steel, the adsorption part 21 uses a magnet, and when the panel 41 is made of plastic, the adsorption part 21 uses a suction cup.
[0049] During installation, the upper and lower extension members 20 are positioned on the upper and lower sides of the extension portion 52 of the air switch 50. When the operating handle 51 of the air switch 50 is not in the closed position, the operating handle 51 will interfere with the limit portion or the sign body 10, causing the adsorption members 21 to be unable to stably adhere to the panel 41. Only when all the operating handles 51 of the air switch 50 are in the closed position can the adsorption members 21 stably contact and adhere to the panel 41. Therefore, when installing the shielded warning sign of the present application, it is possible to check whether the air switch 50 is closed.
