Description

Technical Field

[0001] The utility model belongs to the technical field of highway facilities, in particular to a notice board retracting and deploying device. Background Technique

[0002] A notice board is a sign used to attract people's attention and warn people of a certain specific information, so as to achieve the purpose of notification. Highway notice boards mainly provide road information and command and control traffic, so as to serve as a road language and ensure traffic safety. Since an electronic notice board is only used when needed and is exposed outdoors for a long time, it is easy to damage the notice board. Therefore, in specific situations, the notice board will be retracted into the retracting and deploying device. Traditional storage devices do not have the ability to process electronic notice boards, which will not only affect the storage of the notice board and subsequent use.

[0003] After retrieval, a Chinese patent document (authorized announcement number CN217267056U), an automatic retracting and deploying device for highway notice boards, includes a notice board. An accommodating mechanism is arranged on one side of the outside of the notice board, and an adjusting mechanism is arranged on one side of the outside of the accommodating mechanism. By setting the accommodating mechanism, the notice board is protected from damage caused by long-term exposure outside, and the service life of the notice board is prolonged; by setting the adjusting mechanism, one end of the limit bolt is threadedly connected to the inner side of the groove in the limit block, so as to limit the notice board. The installation block is provided to facilitate the better installation of the device, thus facilitating the use of the staff and adjusting according to the required angle, thereby improving the flexibility of the automatic retracting and deploying device for highway notice boards. The retracting and deploying device can retract and store the notice board, but it does not have the ability to process electronic notice boards, which will not only affect the storage of the notice board and subsequent use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a notice board retracting and deploying device to solve the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a notice board retracting and deploying device, including:

[0006] A storage box with an opening at the bottom;

[0007] An assembly frame, and an electronic notice board for prompting is connected to the inner wall of the assembly frame;

[0008] Two vertical linear motors are respectively installed on the two vertical inner walls of the storage box, and the moving parts of the two vertical linear motors are fixedly connected to the assembly frame;

[0009] The horizontal linear motor is connected to the side of the assembly frame. The moving part of the horizontal linear motor is connected with a cleaning wiper for cleaning the electronic billboard. Two scrapers for cleaning the cleaning wiper are connected to the side of the assembly frame. A storage channel is provided on the side of the assembly frame. A heating wire for drying is connected to the inner wall of the storage channel, and a protective heat-insulating net is connected to the inner wall of the storage channel.

[0010] As a preferred embodiment, the bottom end of the assembly frame is connected with a sealing plate for blocking the storage box through a plurality of connecting rods, and a sealing gasket for improving the sealing performance is bonded to the outer periphery of the sealing plate.

[0015] As a preferred embodiment, a humidity sensor is installed on the inner wall of the storage box.

[0016] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0017] When the billboard retracting and deploying device is in use, the vertical linear motor drives the assembly frame to move downward, so that the electronic billboard in the assembly frame is separated from the storage box to realize traffic information reminder. When the vertical linear motor drives the assembly frame to move upward, the electronic billboard is stored. During storage, the sealing plate cooperates with the sealing gasket to ensure the sealing performance of the storage box and ensure the storage and storage effects of the electronic billboard. Compared with the traditional protection only using a protection frame, the protection effect is better;

[0018] When the billboard retracting and deploying device is in the storage and use states, the horizontal linear motor drives the cleaning wiper to move back and forth, thereby cleaning the electronic billboard. During the cleaning process, the treatment of the scraper can clean the cleaning part of the cleaning wiper, indirectly improving the cleaning effect of the electronic billboard. When the cleaning wiper is not working and is at the storage channel, the heating wire works to dry the cleaning wiper in humid weather, facilitating drying the surface of the electronic billboard during cleaning and not affecting the storage and subsequent use of the billboard;

[0019] When the billboard storage and release device is in storage, if it is in a humid environment, the solenoid valves at the ventilation funnel and the storage box are opened, so that the desiccant packets are exposed, realizing the drying of the air in the storage box. The blowing of the fan realizes ventilation when the desiccant packets are not in use, protecting the electronic billboard.

[0020] The billboard storage and release device can not only store well, but also process the electronic billboard, without affecting the storage and subsequent use of the billboard. Brief Description of the Drawings
