Description
Technical Field
[0001] The utility model relates to the technical field of municipal planning, in particular to an urban planning indicator board which is convenient for decontamination. Background Art
[0002] like Figure 6 As shown, the display board 103 used for urban planning is fixed at the road intersection through the pillar 102 and the base 101. When the display board 103 is used on the urban road, it will inevitably be affected by the outdoor environment in the city and be contaminated with a lot of dirt. When the display board 103 is contaminated with a lot of dirt, it will affect the indication function of the display board 103, and it will also cause a bad impression of the city to the people entering the city to play, so the display board 103 needs to be cleaned regularly. The existing display board 103 needs to be convenient for people to observe the indication information to locate their own position, and it is also to avoid the situation where the display board 103 blocks the road, so it is necessary to position the display board 103 at a higher position through the support tube 3, and at the same time, the display board 103 is set to be double-sided so that it is in the largest visible range during the movement of people.
[0003] Therefore, in the process of cleaning the display board 103, the cleaning staff is usually required to hold a long pole cleaning device to clean the bottom of the display board 103, or the cleaning staff moves themselves to the corresponding display board 103 through a push-up device, thereby achieving the purpose of cleaning the display board 103. However, this method requires the cleaning staff to move twice to achieve the purpose of double-sided cleaning, and it will also consume physical strength due to holding a long pole to clean at a low position, and will consume resources due to the use of a push-up device, which brings inconvenience to the work of the cleaning staff and increases the consumption of municipal resources to a certain extent.

DETAILED DESCRIPTION
[0025] like Figure 1 As shown, in order to conveniently clean the indication surface of the road sign 6, the road sign 6 is connected to the support tube 4 through a rotating mechanism 7, and cleaning scrapers 5 are provided at both lateral ends of the road sign 6, and the cleaning scrapers 5 are slidably matched with the limiting guide frame 8 fixed on the support tube 4. Then, the rotating mechanism 7 is driven by the control port 3 provided on the support tube 4 to rotate the road sign 6, so that the cleaning scrapers 5 cooperate with the limiting guide frame 8 to remove dirt from the indication surface of the road sign 6.
[0026] like Figure 2 As shown, the rotating mechanism 7 includes a rotating shaft 71 rotatably connected to the supporting tube 4, the upper end of the rotating shaft 71 is fixed to a connecting hole opened at the vertical center axis of the road sign 6, the lower end of the rotating shaft 71 passes through a reset disk 73 and is fixed with a driven bevel gear 74, the reset disk 73 is fixed on the inner wall of the supporting tube 4, the opposite surfaces of the reset disk 73 and the rotating shaft 71 are respectively fixed to the two ends of the reset torsion spring 72, the driven bevel gear 74 is transmission-connected with an active bevel gear 75, the active bevel gear 75 is fixed on a power shaft 76, the power shaft 76 is rotatably connected to the inner wall of the supporting tube 4, one end of a power pull rope 77 is fixed on the power shaft 76, the other end of the power pull rope 77 is spirally wound around the power shaft 76 and then extends to the control port 3 as the control end, and the control port 3 is opened in the lower middle part of the supporting tube 4. This makes it convenient for the staff to pull the power rope 77 through the control port 3 to rotate the power shaft 76 under the support of the inner wall of the support tube 4, that is, to drive the active bevel gear 75 to rotate the driven bevel gear 74, and then to rotate the rotating shaft 71 to drive the road sign 6 to rotate. In this process, the cleaning scraper 5 restricted by the limiting guide frame 8 will be pushed to slide. During the sliding process of the cleaning scraper 5, the indicating surface of the road sign 6 will be cleaned. After the staff relaxes the power rope 77, the road sign 6 will be reset by the reset torsion spring 72, thereby achieving the purpose of facilitating repeated cleaning and keeping the position of the road sign 6 stable.
[0027] The power pull rope 77 is made of flexible metal braid, which makes it convenient for the staff to pull and control the road sign 6 to rotate, and can also extend the service life of the power pull rope 77.
[0028] The inner wall of the limiting guide frame 8 is 2 cm larger than the outer wall of the road sign 6, and the connection between the limiting guide frame 8 and the cleaning scraper 5 is dovetail-shaped. Therefore, the cleaning scraper 5 can stably slide and clean along the indicating surface of the road sign 6 under the rotation drive of the road sign 6, completing the complete cleaning of the indicating surface of the road sign 6.
[0029] like Figure 5 As shown, two cleaning scrapers 5 are provided, and are symmetrical with the center of the road sign 6 as the center point, so as to clean the two indicating surfaces of the road sign 6 at the same time, so as to maintain efficient cleaning of the road sign 6. The cleaning scraper 5 includes a limiting slider 51 sliding in the limiting guide frame 8, and a stabilizing bar 52 is fixed on the limiting slider 51, and a scraping bar 53 with an interference fit with the indicating surface of the road sign 6 is fixed on the stabilizing bar 52, and the scraping bar 53 is a cone made of elastic rubber. Then, when the road sign 6 rotates, the two stabilizing bars 52 are pushed to move, and at this time, the stabilizing bars 52 will be restricted by the limiting guide frame 8 and slide along the indicating surface of the road sign 6, so that the scraping bar 53 with an interference fit with the indicating surface of the road sign 6 moves with it, so as to achieve the purpose of conveniently cleaning the indicating surface of the road sign 6. A reflective strip is fixed to the side of the stabilizing strip 52 facing away from the road sign 6. The reflective strip can highlight the outline of the road sign 6, thereby avoiding collision with the road sign 6 under poor lighting conditions, thereby achieving the purpose of protecting the road sign 6 and protecting personnel to a certain extent.
[0030] A closing plate 2 is provided at the control port 3 to prevent anyone from passing through and pulling the power rope 77 at will. The closing plate 2 includes a closing door 23 rotatably connected to the control port 3 through a hinge 21. A lock 22 is provided on the closing door 23. The lock 22 is a structure that can limit the opening to specific people carrying corresponding objects, thereby preventing anyone from pulling the power rope 77 at will to rotate and clean the road sign 6, that is, reducing the rotational wear of the rotating shaft 71 and the support tube 4 to a certain extent, thereby increasing the service life of the rotating shaft 71 and the support tube 4.
[0031] like Figure 2 and Figure 4 As shown, the control port 3 is provided at the lower end of the support tube 4, and the lower end of the power rope 77 is fixedly connected to a labor-saving component 9, which includes a vertical sliding groove 91 provided on the support tube 4, and a linkage plate 92 fixedly connected to the lower end of the power rope 77 is slidably connected in the sliding groove 91. The setting of the linkage plate 92 can assist the staff to extend their feet into the control port 3 to step on the linkage plate 92, thereby driving the power rope 77 to move downward to rotate the road sign 6.
[0032] The end of the linkage plate 92 facing the control port 3 is provided with a treading groove 94, which can facilitate the staff to stably tread the linkage plate 92 to move the control end of the power pull rope 77 downward, thereby controlling the road sign 6 to rotate and clean. The two ends of the return spring 93 are respectively fixed to the opposite surface of the linkage plate 92 and the chassis 1, thereby preventing the return torsion spring 72 from bearing the weight of the linkage plate 92 and causing the road sign 6 to be reset inaccurately, that is, avoiding affecting the normal indication function of the road sign 6, and at the same time, assisting the return torsion spring 72 to reset the road sign 6 for road indication.
[0033] like Figure 1 and Figure 2 As shown, when the road sign 6 needs to be cleaned, the staff opens the lock 22 with the corresponding key, and then rotates the closed door 23 through the hinge 21, and then exposes the control port 3. Then the staff can pass through the control port 3, hold the power pull rope 77 or step on the stepping groove 94 to move the power pull rope 77 downward. When the power pull rope 77 moves downward, it will drive the power shaft 76 to have a rotational force. At this time, the power shaft 76 will rotate stably with the inner wall of the support tube 4 as support, and then the power shaft 76 will drive the driving bevel gear 75 to rotate the driven bevel gear 74. When the driven bevel gear 74 rotates, it will drive the road sign 6 to rotate through the rotating shaft 71. During the rotation of the rotating shaft 71, the supporting tube 4 will be the center of the circle, and then the road sign 6 will rotate with the vertical center axis concentric with the center of the supporting tube 4 as the center of the circle. When the road sign 6 rotates about its own vertical central axis, it will push the two centrally symmetrical stabilizing bars 52, and the two stabilizing bars 52 will slide in cooperation with the limiting slider 51 under the restriction of the limiting guide frame 8, thereby driving the two scraping bars 53 to clean the two indicating surfaces of the road sign 6. This avoids the existing process of cleaning the road sign 6, where the worker needs to move his position several times to perform the relatively cumbersome cleaning steps, thereby improving the convenience of cleaning the road sign 6.
[0034] The parts not explained in the above embodiments, such as how the reset torsion spring 72 and the reset spring 93 reset the rotating shaft 71 and the linkage plate 92, why the road sign 6 has two indication surfaces, how the lock 22 cooperates with the closing door 23 to restrict people from opening and closing the control port 3, and how the power pull rope 77 is made by flexible metal braiding, should be understood as the prior art known or should be known to those skilled in the art.
