Description

Technical Field

[0001] The utility model relates to the field of toll station indicators, in particular to a high-speed toll station indicator with a cleaning function. Background Art

[0002] The indicator at a highway toll booth is an LED display screen installed under the ceiling of the toll booth lane or the ETC dedicated lane. It is connected to the traffic management system and is used to publish preset information, such as traffic conditions, safety reminders, weather information, road closures and construction information, and emergency road conditions, etc. Therefore, this indicator is also called a variable information board. The indicator needs to ensure sufficient clarity, penetration, and reliability when working to ensure that the information above is clearly seen by the driver. However, due to the large amount of dust raised by vehicles on the lane, dust is easily accumulated on the surface of the indicator, which reduces the clarity of the indicator over time. However, since the indicator is generally set at a high position and is located in a relatively dangerous area such as above the lane, manual cleaning is not only inconvenient, but also inefficient and prone to danger.

DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings and specific embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] refer to Figures 1 to 4 The high-speed toll station indicator with a cleaning function described in this embodiment includes: a mounting plate 1, a display screen 2, a screw rod 3, a slide rod 4, a cleaning pipe 5, a drive motor 6 and a blast device 7. The mounting plate 1 is vertically arranged, and the upper end of the mounting plate 1 can be fixed on the lower surface of the ceiling above the lane of the high-speed toll station when in use. The display screen 2 is located on the front wall surface of the mounting plate 1. The display screen 2 can be fixed on the front wall surface of the mounting plate 1 or embedded in a groove on the front wall surface of the mounting plate 1.

[0021] The screw rod 3 and the slide rod 4 are both arranged horizontally, and are respectively arranged at the upper and lower parts of the back side of the mounting plate 1. Wherein: both ends of the screw rod 3 are rotatably connected to the connection holes of the support block, and the support block is fixed to the upper part of the back side of the mounting plate 1. Both ends of the slide rod 4 are fixed to another set of connection holes of the support block, and the support block is fixed to the lower part of the back side of the mounting plate 1. Both ends of the cleaning pipe 5 are closed, and it is vertically arranged in front of the display screen 2. The cleaning pipe 5 has an air jet hole facing the display screen 2, so that the display screen 2 can be dusted by the ejected airflow.

[0022] The upper and lower parts of the mounting plate 1 are respectively provided with strip openings 8 corresponding to the screw rod 3 and the slide rod 4, and both ends of the cleaning tube 5 are respectively connected to the screw rod 3 and the slide rod 4 through sliders 9. Specifically, the sliders 9 are two pieces, both of which are rectangular structures. One end of the first slider 9 passes through the strip opening 8 on the upper part of the mounting plate 1 and is then sleeved on the screw rod 3 and the two are threadedly connected, and the other end of the first slider 9 is fixedly connected to the upper end of the cleaning tube 5. One end of the second slider 9 passes through the strip opening 8 on the upper part of the mounting plate 1 and is then sleeved on the slide rod 4 and the two are slidably connected, and the other end of the second slider 9 is fixedly connected to the lower end of the cleaning tube 5, and both sliders 9 can slide left and right in the corresponding strip openings 8. The indicator of this embodiment hides the screw rod 3, the slide rod 4, the drive motor 6 and the blast device 7 and other components at the rear of the mounting plate 1, avoiding the obstruction of the display screen 2 on the front wall of the mounting plate 1.

[0023] The driving motor 6 and the blowing device 7 are both fixed to the back of the mounting plate 1, and the driving motor 6 is connected to one end of the screw rod 3 by transmission. The air outlet of the blowing device 7 is connected to the cleaning tube 5 through a flexible tube 10, and the flexible tube 10 is a spiral tube made of plastic. When in use, the driving motor 6 and the blowing device 7 are started, and the screw rod 3 is driven to rotate under the drive of the driving motor 6, so that the slider 9 moves along the screw rod 3 and the slide bar 4, and the cleaning tube 5 moves from one end of the display screen 2 to the other end. In this process, the airflow delivered by the blowing device 7 to the cleaning tube 5 can blow away the dust on the display screen 2 after passing through its air jet hole. As the cleaning tube 5 sweeps across the display screen 2, the display screen 2 can be completely cleaned once. Through the forward and reverse rotation of the driving motor 6, the reciprocating motion of the cleaning tube 5 can be realized, which not only helps to improve the cleaning effect, but also is convenient and efficient.

[0024] In another embodiment, reference Figure 3 and Figure 4 The other end of the flexible tube 10 of the high-speed toll station indicator with cleaning function in the above embodiment is connected to one end of the channel 11 on the slider 9 corresponding to the slide bar 4, and the cleaning tube 5 is connected to the other end of the channel 11 through a connecting tube and the inner cavities of the two are connected. The slider 9 corresponding to the slide bar 4 has a sliding hole 12, and the slider 9 slides on the slide bar 4 through the sliding hole. The channel 11 runs through the front end face and the rear end face of the slider 9, and the channel 11 is located at the upper part or the lower part of the sliding hole 12, so that when the cleaning tube 5 moves, the flexible tube 10 is on the back of the mounting plate 1.

[0025] In another embodiment, reference Figure 3One end of the screw rod 3 of the high-speed toll station indicator with a cleaning function in the above embodiment is connected to a driven wheel 13, which is connected to the driving wheel 14 on the driving motor 6 through a transmission belt 15 to drive the screw rod 3 to rotate.

[0026] In another embodiment, reference Figure 3 The mounting plate 1 of the high-speed toll station indicator with a cleaning function of the above embodiment has a box 16 behind it, the driving motor 6 and the air blowing device 7 are both located in the box 16, and the driving wheel 14 is located outside the box 16. The air outlet of the air blowing device 7 is located on the outer wall of the bottom surface of the box 16.

[0027] In another embodiment, the two ends of the slide bar 4 of the high-speed toll station indicator with a cleaning function in the above embodiment are provided with position sensors, which are connected to the controller of the drive motor 6. When the position sensor senses that the slider 9 on the slide bar 4 moves to the end of the slide bar 4, it sends a signal to the controller, and the controller can control the drive motor 6 to reverse and the cleaning tube 5 to move in the opposite direction. The reciprocating motion of the cleaning tube 5 can continuously clean the surface of the display screen 2 to improve the dust removal effect. The controller can be set at a position at the toll station that is convenient for the staff to control. The controller has control switches for the drive motor 6 and the blower 7, and can also set adjustment switches for the running time, the power of the blower 7, etc., to set the automatic cleaning time and the cleaning blowing intensity.

[0028] The technical contents not described in detail in this specification are all existing technologies known to those skilled in the art.

[0029] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
