Description

Technical Field

[0001] The invention relates to the technical field related to tourist signboards, and in particular to a tourist signboard for tourist guides. Background Art

[0002] With the continuous improvement of people's living standards, tourism has become the first choice for people's leisure and entertainment projects; in larger tourist attractions, in order to guide tourists to various scenic spots, tourist signboards are installed in places with more people and various forks; signboards are a type of traffic signs, used to instruct vehicles and pedestrians to drive in the specified direction and location. The signboards for tourist guidance in scenic spots are to mark locations, guide routes and point to specific landmarks. The use of signboards in different occasions and regions also has its own characteristics; signboards are from the perspective of tourists, and provide directions and route prompts for various scenic spots, public facilities and service facilities in tourist attractions, including direction signs and place signs, which cooperate with each other. Marking the places that must be marked is conducive to improving the service efficiency of the scenic area; Most tourist signboards have text descriptions of the location, subsequent route distribution, and precautions on the route, etc. However, tourist signboards are usually installed outdoors. The notice part with precautions is easily damaged or faded after long-term use, especially after being exposed to severe weather such as exposure to the sun or sandstorms, which affects tourists' understanding of the contents of the notice part of the tourist signboard, especially the precautions. It is very easy for tourists to get injured due to lack of clear understanding of the precautions on the road section. At the same time, tourist signboards are mostly placed on both sides of the road. Dust is easily accumulated on the surface of the sign over a long period of time, which will also affect tourists' observation of the marked location on the sign. Therefore, staff are required to manually clean the surface of the signboard regularly, which is labor-intensive, time-consuming and labor-intensive. Summary of the invention

[0026] The following is a further description of the method and principle of using the technical solution in this specific implementation method in conjunction with the accompanying drawings: When tourists reach the tourist sign, they can start the motor 35 through the PLC control panel 6 next to the sign. The power output shaft of the motor 35 rotates to drive the first transmission shaft 34 axially connected to it to rotate. The rotation of the first transmission shaft 34 drives the first sprocket 36 concentric with it to rotate. The rotation of the first sprocket 36 drives the second sprocket 42 to rotate through the transmission chain. The rotation of the second sprocket 42 drives the second transmission shaft 40 concentric with it to rotate. The rotation of the second transmission shaft 40 drives the map taking wheel 41 concentric with it to rotate. Since the introduction low point of the introduction ramp 15 is slightly higher than the center of the map taking wheel 41, the map taking slot 43 on the map taking wheel 41 will complete the operation of taking out the scroll maps one by one at a position higher than the center of the map taking wheel 41, thereby preventing the map in the map taking slot 43 from sliding down when it is at the low point. The introduction ramp 15 can help the scroll map always slide toward the map taking slot 43. The map taking wheel 41 rotates continuously, and the map can be rotatably fed into the discharge platform tube 18 through the map taking slot 43, and then the map is rolled onto the receiving ramp 19 by the inclined discharge platform tube 18, and the map is blocked by the stop plate 20 to prevent it from sliding off the ground; the staff can replenish the map through the map feeding slot 13; the length of the storage cavity 12 is slightly greater than the length of the scroll map and the length of the map taking slot 43 is equal to the length of the storage cavity 12, which can ensure that the scroll map is always in an orderly stacked state in the storage cavity 12, avoiding the situation where the map taking slot 43 cannot take out the map due to disorderly stacking; The synchronous first transmission shaft 34 rotates, thereby causing the driving rack 38 to slide along the spiral slide groove 37 through the shaft protrusion 39 to complete a reciprocating slide; the driving rack 38 moves to drive the first gear 44 engaged with it to rotate, and the rotation of the first gear 44 drives the screw shaft 45 to rotate, thereby driving the triangular slide column 47 screwed with it to move up along the triangular slide groove 23, and the triangular slide column 47 moves up and drives the incomplete gear 56 engaged with it to rotate through its three tooth surfaces, thereby driving the arrow indicator 55 to rotate to the cleaning groove 24, and in this process, the stains on its surface can be preliminarily cleaned by the bristles 25; The synchronous upward movement of the triangular sliding column 47 drives the driving rod 49 on its top to move upward. The upward movement of the driving rod 49 causes the first ear seat 50 on its shaft body to pull the second ear seat 52 through the connecting rod 51, and then the water stop plate 53 slides along the T-shaped slide groove 31 through the T-shaped sliding block 54 at its bottom, thereby exposing the water outlet 32, and the water source in the water storage chamber 28 can flow into the drainage channel 33 from the water outlet 32, and the water source is introduced into the cleaning tank 24 through the drainage channel 33 to further clean the surface of the arrow indicator sign 55; synchronously, when the driving rack 38 starts to move back and reset, the triangular sliding column 47 moves down and resets, the arrow indicator sign 55 rotates to resume its direction, and the water stop plate 53 re-blocks the water outlet 32.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
