Description

Fingerpost

Technical Field

The invention relates to a guidepost, in particular to an intelligent guidepost. Belongs to the IPC classification system of E01F9/00 and G09F 9/00.

Background

Modern traffic develops rapidly, and urban road and intersection all are equipped with various traffic signs, and in the current traffic sign, the sign is shown for single 360 degrees is adjustable mostly, can only instruct single direction, and the position is marked to a few traffic signs adoption diversified sign, but its intelligent degree is lower, can not carry out interactive operation.

The intelligent traffic sign has appeared afterwards, and these intelligent traffic signs can diversely rotate to intelligent degree is very high, nevertheless faces thereupon is the comparatively harsh environmental condition of nature, makes traffic sign especially intelligent traffic sign face bad weather conditions such as wind, sleet, has appeared having for this reason and has prevent wind, set up the traffic sign of functions such as protection casing, has solved these problems. However, in the prior art, the height of the current intelligent traffic sign is generally high, the visual height of the current intelligent traffic sign is generally consistent with that of an adult, which facilitates the adult to observe related traffic indication information, but for disabled persons with inconvenient legs and feet or pupils who can learn words, the reading of related information is not convenient, at the moment, the height of the sign is set to be short in order to take the convenience of the sign for reading into account, but the applicant finds that the problem is faced with the other problem, as some pupils are in active and active years, the sign can be actively used for 'jumping up' competition, the sign is used as a competition target, the sign is flapped or pulled by hands after jumping in place, and some remote areas, some people with poor quality are used as a stand for taking up clothes or airing clothes, these all result in a signpost that is subjected to extreme weight in the vertical direction and is prone to damage.

The invention carries out detailed retrieval through the state intellectual property office official website retrieval service system, obtains the following prior arts, and simply introduces the prior arts so as to better understand the inventive concept of the invention and show the technical advantages and the technical characteristics of the invention.

Through retrieval, the technical improvement of the prior fingerpost under the severe natural environment is mainly on the improvement of the stress of the fingerpost in the horizontal direction in the case of strong wind, but is not improved in the vertical direction in the two cases.

In the prior retrievable patent, the design of the windproof sign can be roughly divided into three types, namely a reinforced upright column type, a ventilation slot ventilation type and an indicator board control type.

The reinforced column type mainly uses a method of improving the structure and fixing mechanism of the column. Such as: the application number is CN201620419959.3, and the name is 'a traffic sign with the function of buffering wind force'; the ventilation groove ventilation type mainly utilizes the principle that the ventilation groove reduces the contact area of the indicating plate and wind to ensure that the indicating plate is protected to a certain extent. Such as: the Chinese utility model patent with application number CN201620187730.1 and name "ventilated traffic sign"; the Chinese utility model patent with the application number of CN201620573113.5 and the name of windproof traffic sign; the Chinese utility model patent with the application number of CN201520230665.1 and the name of 'a road sign'; the Chinese utility model patent with the application number of CN201420774351.3 and the name of windproof sign. The indicator board control type is also based on the principle of reducing the frontal windward area, but the realization method is to control the indicator board according to the wind power size to reduce the windward area. The control method comprises two methods, one method is based on various wind power or wind speed sensors to monitor wind power, and when the wind power reaches a certain value, the indicator board is controlled to rotate, such as: the application number is CN201521095225.6, the name is "a prevent wind traffic sign" Chinese utility model patent, this mode control is passive control, is comparatively stable rigid connection before rotator and the rotation axis, just rotates after receiving the instruction. Yet another control is wind-based automatic control, such as: the utility model discloses a chinese utility model patent of application number CN201520679347.3, the name is "a suspension type prevent wind road sign", the "prevent wind signpost" that CN205827813U disclosed, "loss prevention signpost" that CN206097748U disclosed, "the direction is adjusted automatically tablet" that CN205443998U disclosed, "unstable ground flexonics before automatic control mode rotator and the rotation axis, when wind-force reached a definite value, the resistance that can overcome flexonics made the sign rotatory.

The prior art CN201810300596 discloses a road guideboard, CN201710032287 discloses a power supply system of an advertisement sign, CN201710032286 discloses a power-saving LED advertisement sign, and CN201620252042 discloses a smart multidirectional indication road sign, and the prior arts relate to signs or road signs which are adopted at present and have 360-degree rotation functions, and have the problem of longitudinal overload introduced in the application.

(1) although having a turning function, lacking a function of longitudinally preventing overload;

(2) under severe natural environment, the method has prevention or response measures for natural disasters such as rain, snow, strong wind and the like, but lacks defense measures for artificial damage;

in addition, the applicant searches that the technology for dealing with the motor overload in the guidepost is only in the state of circuit protection, and the guidepost is not prevented or protected when the condition is reliably generated on the guidepost through the linkage relation of the mechanical device from the mechanical device.

That is, the applicant finds that although the existing intelligent indicator is improved in coping with natural harsh environment or disaster by searching the prior art, there are many means on the basic function, but when the children are exposed to the phenomena of the longitudinal or vertical load bearing, such as the phenomenon that the children accidentally or intentionally flick, flap, drag, and some adults solarize clothes, absent precautions, these skinning children or less qualified adults are usually educated or warned only by means of human management or warning, but cannot solve the problem technically, that is, although these phenomena exist in real life, but few people pay attention to the technical proposal to provide the relevant technical means for solving the technical problem, namely, after searching, the prior art gives technical suggestions and does not discover similar technical means.
