Description

Technical Field

[0001] The invention relates to the technical field of signboards, in particular to a signboard which is convenient for installation and replacement, and is used for the operation of replacing signboards in a transformer substation. Background Art

[0002] Substation signs are important facilities used to remind, warn or indicate safety information within the station. They are mainly used to indicate the work location and work equipment of on-site workers, and play a key role in ensuring the health and safety of on-site workers.

[0003] At present, the process of converter station signboards mainly adopts electroplating spraying technology. Under long-term sunlight exposure, the signs fade seriously and age frequently. In order to ensure the safety of on-site operations, it is necessary to regularly maintain and replace the content. Since the signboards are fixed by binding, fixing and pasting, the appearance of the building or equipment will be affected during replacement.

[0004] Taking the above factors into consideration, a signboard is designed that is easy to maintain and replace on site, which can reduce the manpower waste and impact on equipment appearance caused by on-site replacement of signboards.

[0005] In the prior art, on-site sign replacement requires the removal of rivets from the building's color steel plate exterior wall, the reinstallation of rivets, and the removal of sign stickers, which has a certain impact on the appearance of the building and equipment. The replacement process of rivet-installed signboards will also damage the building's color steel plate exterior wall, affecting the anti-sand insulation measures between equipment; currently, signboard maintenance and replacement requires the cleaning of the original signboard fixtures, which takes a long time and requires on-site personnel to supervise and implement in order to avoid mechanical injuries during work. The maintenance process requires a lot of time and personnel.

[0006] In the prior art, China's authorized patent announcement number: CN 208834649U discloses a self-locking telescopic vertical inspection site signboard, including a signboard body, a fastener, a telescopic assembly, a self-locking assembly and a chassis. The upper end of the telescopic assembly is connected to the signboard body by a fastener, and the lower end of the telescopic assembly is embedded in the chassis. The self-locking assembly includes a linked telescopic rod, a button, a bayonet and a spring. The telescopic assembly adopts a plurality of sections of telescopic rods, and the linked telescopic rod adopts a plurality of sections of telescopic connecting rods. Each bayonet is fixedly arranged on one side of each section of the telescopic connecting rod. The telescopic rod is provided with a side hole matched with the bayonet. One end of the spring is arranged on the inner wall of the telescopic assembly, and the other end contacts the linked telescopic rod. When the button is pressed, the bayonet is squeezed out of the side hole on the telescopic assembly, thereby adjusting the height of the telescopic assembly. The self-locking telescopic function of the utility model can ensure that the signboard is firmly set at the required position, avoiding wasting time in searching for other bracket-like structures.
