Description

Technical Field

[0001] The utility model belongs to the technical field of pedestrian safe passage display devices, and specifically relates to a road pedestrian safe passage display device. Background Art

[0002] As urban traffic becomes increasingly busy, pedestrian safety has become a concern. In order to solve this problem, various road pedestrian safety display devices have been developed. The main function of these devices is to provide pedestrians with clear and explicit traffic guidance and safety instructions to ensure that they cross the road safely.

[0003] Currently, the road pedestrian safety display device on the market usually consists of an integrated housing, a controller and a display light arranged inside the housing. This design can effectively protect the internal controller and display light from the external environment. Under the control of the controller, the display light can switch between red, green, yellow and other colors to provide clear traffic instructions for pedestrians.

[0004] However, existing road pedestrian safety display devices still face some challenges and problems. First, since these devices are usually installed outdoors and directly exposed to the environment, they are easily affected by dust, dirt, etc. This will reduce the clarity and visibility of the display lights, making it difficult for pedestrians to identify the indication information at a certain distance. In the prior art, cleaning these devices mainly relies on manual wiping using cleaning tools such as brushes and cloths. This method is not only inefficient, but also easily affected by human factors, such as incomplete cleaning and omissions.

[0005] Secondly, existing road pedestrian safety display devices usually adopt an integrated design. This means that once a part is damaged or fails, the entire device needs to be replaced. This not only increases the maintenance cost, but also prolongs the downtime of the device, affecting the safe passage of pedestrians.

[0006] To this end, we proposed a road pedestrian safety passage display device, which can not only achieve automatic cleaning, but also be easy to replace if damaged. Utility Model Content

[0007] The purpose of the present invention is to provide a road pedestrian safe passage display device, which can not only realize automatic cleaning, but also is easy to replace in case of damage.

[0008] The technical solutions adopted in this utility are as follows:

[0009] A road pedestrian safety passage display device comprises a chassis, a first shell for mounting a controller body is arranged on the top of the chassis, a rotating assembly is arranged inside the first shell, a second shell for mounting a display light is arranged on the top of the first shell, and the display light is controlled by the controller body;

[0010] A display groove and a de-impurity groove are provided on the outer side of the second shell, a cylindrical protective shell is rotatably arranged inside the second shell, the cylindrical protective shell is connected to the rotating assembly, a hollow shell connected to the de-impurity groove is provided on the outer side of the second shell, a de-impurity roller is rotatably arranged inside the hollow shell, and the de-impurity roller is fitted with the cylindrical protective shell through the de-impurity groove.

[0011] Furthermore, the width of the display slot is one quarter of the circumference of the cylindrical protective shell.

[0012] Furthermore, the length of the impurity removal roller is the same as the length of the impurity removal groove.

[0013] Furthermore, a debris removal hole is opened at the bottom of the hollow shell.

[0014] Furthermore, the rotating assembly includes a motor fixedly disposed inside the first shell, and an output end of the motor passes through the first shell and the second shell and is connected to the cylindrical protective shell.

[0015] Furthermore, the first shell, the second shell and the cylindrical protective shell are all provided with through holes.

[0016] The technical effects achieved by this utility model are:

[0017] 1. First, the controller body drives the rotating assembly to rotate, and the rotating assembly drives the cylindrical protective shell to rotate inside the second shell. When the dirty surface of the cylindrical protective shell rotates to the position of the impurity removal groove, because the impurity removal roller fits the cylindrical protective shell, it drives the impurity removal roller to rotate in the hollow shell during rotation, thereby removing impurities.

[0018] 2 The segmented design of the first shell and the second shell facilitates subsequent damage and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0028] like Figure 1-6 As shown, the technical solution adopted by the present invention is specifically as follows: a road pedestrian safe passage display device, including a chassis 1, a first shell 2 for mounting a controller body is arranged on the top of the chassis 1, a rotating assembly is arranged inside the first shell 2, and a second shell 3 for mounting a display light is arranged on the top of the first shell 2, and the display light is controlled by the controller body; the first shell 2 and the second shell 3 are connected by a snap buckle, and the segmented design can be convenient for assembly and disassembly. Even if it is damaged later, it can be replaced without replacing the entire device, thereby achieving the effect of cost saving.

[0029] A display slot 4 and a de-impurity slot 5 are provided on the outside of the second shell 3, and a cylindrical protective shell 6 is rotatably provided inside the second shell 3. The cylindrical shell fits the second shell 3, which not only makes the rotation stable but also achieves a waterproof effect.

[0030] The cylindrical protective shell 6 is connected to the rotating assembly. A hollow shell 7 connected to the impurity removal groove 5 is arranged on the outside of the second shell 3. An impurity removal roller 8 is rotatably arranged inside the hollow shell 7. The impurity removal roller 8 is fitted with the cylindrical protective shell 6 through the impurity removal groove 5.

[0031] Its working principle is as follows: first, the display light is controlled by the controller body. Because the whole device is in the outside world for traffic control, dust and dirt may adhere to the surface of the cylindrical protective shell 6 through the display slot 4, causing the display content to be blurred or blocked. At this time, the controller body drives the rotating assembly to rotate, and the rotating assembly drives the cylindrical protective shell 6 to rotate inside the second shell 3. When the dirty surface of the cylindrical protective shell 6 rotates to the position of the impurity removal slot 5, because the impurity removal roller 8 fits the cylindrical protective shell 6, it drives the impurity removal roller 8 to rotate in the hollow shell 7 during rotation, thereby removing impurities. The device can not only achieve automatic cleaning, but also facilitates damage and replacement.

[0032] In order to ensure that the light of the display lamp is clearly displayed, the cylindrical protective housing 6 is a transparent structure, and its material is a transparent plastic material such as polycarbonate, acrylic, etc. These materials have the advantages of high transparency, impact resistance, light weight, etc., and can effectively protect the display lamp from external factors while maintaining a clear display effect.

[0033] At the same time, the width of the display slot 4 is one-fourth of the circumference of the cylindrical protective shell 6. This width ratio ensures that the light emitted by the display lamp can fully illuminate the area of ​​the display slot 4 and maintain sufficient brightness to make the displayed content clearly visible. At the same time, it can reduce the interference of external light and improve the display clarity.

[0034] In order to enable the impurity removal roller 8 to remove impurities on the cylindrical protective shell 6 more comprehensively, the length of the impurity removal roller 8 is the same as the length of the impurity removal groove 5, so that the impurities on the cylindrical protective shell 6 can be removed more comprehensively and the impurity removal effect is improved.

[0035] In order to remove the impurities on the impurity removal roller 8 without causing secondary pollution, a discharge hole is provided at the bottom of the hollow shell 7 so that the removed impurities can be discharged through the discharge hole.

[0036] In order to further enhance the impurity removal effect, the hollow shell 7 is detachably connected to the second shell 3, and the connection method here is a snap connection or a bolt connection. This method makes it convenient for the hollow shell 7 to drive the impurity removal roller 8 to be removed for cleaning, thereby further enhancing the impurity removal effect.

[0037] like Figure 4 As shown, the rotating assembly includes a motor 9 fixedly arranged inside the first shell 2. The output end of the motor 9 passes through the first shell 2 and the second shell 3 and is connected to the cylindrical protective shell 6. The motor 9 drives the cylindrical protective shell 6 to rotate, thereby removing impurities.

[0038] Among them, the motor 9 is a stepper motor 9, and its model is a DC stepper motor 9. The stepper motor 9 can perform stepping motion without frequent rotation. The stepper motor 9 can save power and does not affect the lighting effect of the display lamp.

[0039] At the same time, the motor 9 is electrically connected to the controller body, and the motor 9 is controlled to work by the controller body.

[0040] It should be noted that the motor 9 of the utility model is started by the controller body, which is a programmable controller that can be set to rotate once a day, that is, 24 hours, according to the required requirements. It belongs to the prior art and will not be described in detail here.

[0041] When the display lamp and the control body are working, heat is generated. The first shell 2, the second shell 3 and the cylindrical protective shell 6 are all provided with through holes 10. The provision of the through holes 10 can discharge the heat, thereby achieving a heat dissipation effect.

[0042] If it is winter, there is no need to dissipate heat because the outside temperature is low. At this time, the motor 9 drives the cylindrical protective shell 6 to rotate, so that the through holes 10 on the cylindrical protective shell 6 are staggered with the through holes 10 on the first shell 2 and the second shell 3, thereby preventing cold air and water from entering and improving the use effect.

[0043] like Figure 1 As shown, a solar panel is arranged on the top of the second shell 3, and the solar panel absorbs heat to provide electricity, thereby achieving the effect of saving energy.

[0044] It should be noted that solar panel technology belongs to the existing technology and will not be elaborated in detail here.

[0045] The working principle of the utility model is as follows: first, the display light is controlled by the controller body. Because the whole device is in the outside world for traffic control, dust and dirt may adhere to the surface of the cylindrical protective shell 6 through the display slot 4, causing blur or obstruction of the displayed content. At this time, the controller body drives the rotating assembly to rotate, and the rotating assembly drives the cylindrical protective shell 6 to rotate inside the second shell 3. When the dirty surface of the cylindrical protective shell 6 rotates to the position of the impurity removal slot 5, because the impurity removal roller 8 fits the cylindrical protective shell 6, it drives the impurity removal roller 8 to rotate in the hollow shell 7 during rotation, thereby removing impurities. The device can not only realize automatic cleaning, but also facilitates damage and replacement.

[0046] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
