Detailed Description

As shown in fig. 1 to 7, the road signboard with good wind resistance comprises a vertical column 1, a cantilever 2 arranged at the upper part of the vertical column 1 and a signboard main body 3 arranged on the cantilever 2. The upright post 1 is arranged on the road side and serves as an installation base of the invention, and the cantilever 2 is transversely arranged on the upper part of the upright post 1 and serves as a carrying part of the signboard main body 3.

Be provided with a plurality of wind-force uninstallation holes 4 on the signboard main part 3, wind-force uninstallation hole 4 be exactly the hole that is used for reducing the load that wind-force was applyed on signboard main part 3, it is vertical bar usually, and what this kind of mode can be better installs elastic diaphragm 5, and elastic diaphragm 5 makes the wholeness of whole identification face better when warping simultaneously. As for the number of the wind discharging holes 4, as shown in fig. 1 and 2, the wind discharging holes 4 may be provided in two rows at the upper and lower portions of the signboard main body 3. Of course, it is also possible to choose to provide more wind-off-load holes 4. The wind power unloading device is characterized in that an elastic diaphragm 5 matched with the wind power unloading hole 4 is arranged in the wind power unloading hole, the upper end and the lower end of the elastic diaphragm 5 are fixedly connected with the signboard main body 3, and the surfaces of the elastic diaphragm 5 and the signboard main body 3 facing the vehicle come direction form a signboard surface together.

The working principle of the invention is that when the wind power is large, the elastic diaphragm 5 can be blown open, so that the airflow can pass through the wind power unloading hole 4 and be guided out from two sides of the elastic diaphragm 5 under the guidance of the elastic diaphragm 5. The elastic membrane 5 should be sufficiently elastic to keep it in a stretched condition under normal conditions, yet deform when subjected to wind of a certain intensity, in order to direct the air flow and to unload the wind. The elastic membrane 5 can be made of flexible elastic material, and is preferably a high weather resistance silica gel membrane in order to adapt to environments such as high temperature, sunshine and the like. On the basis of satisfying the installation structure strength, the elastic membrane 5 can be installed in the wind unloading hole 4 by adopting various modes, such as: bonding, bolted connection, joint, crimping etc. also can be as shown in fig. 4 and 5, be provided with on the pore wall at wind-force uninstallation hole 4 upper and lower both ends with elastic diaphragm 5 matched with slot 6, elastic diaphragm 5 passes through rivet 7 fixed setting in slot 6.

In the using process of the invention, under the normal weather condition, as shown in fig. 4, the elastic membrane 5 is in a stretched state, and the surface of the elastic membrane 5 and the surface of the signboard main body 3 form a signboard surface together, thereby ensuring the continuity of the signboard. When the signboard is influenced by high wind power, as shown in fig. 5, the wind power blows the elastic membrane 5, so that the airflow can blow through the wind power unloading holes 4, the windward area of the signboard main body 3 is greatly reduced, and the wind power load of the signboard main body is further reduced; in addition, even if the elastic membrane 5 is in a blown arc state, the elastic membrane still has enough sign surface under the observation angle of the coming direction of the vehicle, has small adverse effect on the sign guiding function, and can excellently reduce the influence on the sign main body in the states of medium and strong wind.

After the design of wind power unloading is adopted, the influence of medium and strong wind can be greatly reduced, but when the wind power unloading device encounters disastrous super-wind climate, the disastrous influence cannot be completely avoided by only adopting the design of the wind power unloading holes 4. Therefore, in order to deal with the condition that island and coastal areas are influenced by typhoon, hurricane and the like, the invention can further perfect the whole wind-proof performance, in particular to the stress buffering design of the upright post 1 and the cantilever 2.

Specifically, the invention can also reduce the moment length between the signboard main body 3 and the upright post 1 when the signboard main body 3 is subjected to wind power by actively moving the signboard main body 3 towards the upright post 1, thereby relieving the stress condition of the cantilever 2. As shown in fig. 3, a sliding collar 8 is fixedly arranged at a position on the back of the signboard main body 3 opposite to the cantilever 2, and the sliding collar 8 is sleeved on the cantilever 2 and forms a sliding fit with the cantilever 2. The signboard body 3 can reciprocate along the cantilever 2 under the driving of the driving mechanism. As shown in fig. 1, the sign main body 3 is positioned on the cantilever 2 in a normal use state, and fig. 2 shows that the sign main body 3 is moved close to the pillar 1 for self-protection in case of a disaster weather.

Since the sliding collar 8 is used as a contact part with the cantilever 2, in order to ensure the smoothness of sliding with a simple structure, the invention preferably includes that, as shown in fig. 6, the sliding collar 8 is fixedly connected with the signboard main body 3 through a fastening bolt 16, an annular rotating groove is arranged on the inner wall of the sliding collar 8, a rotating ring 17 which is matched with the rotating groove is arranged in the rotating groove, the rotating ring 17 is in sliding fit with the rotating groove, and the sliding collar 8 is in contact with the cantilever 2 through the rotating ring 17. In the process of the movement of the sliding lantern ring 8, the sliding friction force between the sliding lantern ring and the cantilever 2 can be partially converted into the rotation of the rotating ring 17, so that the friction force is reduced, and the sliding smoothness is improved. On this basis, the back of signboard main part 3 that each cantilever 2 corresponds is provided with three slip lantern ring 8, and three slip lantern ring 8 is along the length direction evenly distributed of signboard main part 3.

In order to improve the stability supported by the cantilever 2, the two cantilevers 2 are arranged, and the two cantilevers 2 are distributed in parallel up and down, and then, a driving mechanism is usually arranged between the two cantilevers 2 to improve the symmetry and the stability of the whole. When a drive mechanism described below is used, the drive screw 9 is disposed between the two booms 2.

Regarding specific driving mode, actuating mechanism includes the drive lead screw 9 with cantilever 2 parallel arrangement, drive lead screw 9 overcoat is equipped with sliding block 10, sliding block 10 and drive lead screw 9 screw-thread fit, and sliding block 10 and signboard main part 3 rigid coupling. The driving mechanism further comprises a driving motor 11, and the driving motor 11 is in transmission connection with one end of the driving screw rod 9. The wind power detection device is characterized by further comprising a wind power detection mechanism 12 arranged at the top end of the upright post 1 and a control box 13 arranged at the bottom of the upright post 1, wherein the wind power detection mechanism 12 and the driving motor 11 are electrically connected with a controller arranged in the control box 13. The wind force detection mechanism 12 is a device for detecting the magnitude of wind force, i.e., a wind detector. In addition, in order to ensure the stability of the driving screw 9 and the cantilevers 2, it is preferable that the two cantilevers 2 are connected to each other through a short connecting rod 14, a screw seat 15 matched with the driving screw 9 is further disposed on the short connecting rod 14, and one end of the driving screw 9, which is far away from the column 1, is disposed on the screw seat 15 and forms a rotating fit with the screw seat 15.

In the use, wind-force detection mechanism 12 is used for detecting the wind-force situation, and when reaching calamity wind-force early warning, driving motor 11 starts, drives drive lead screw 9 and rotates, and then drives sliding block 10 along the length direction motion of drive lead screw 9, finally drives signboard main part 3 towards the direction motion of keeping away from cantilever 2 overhanging end. By folding the signboard body 3 to a position close to the upright post 1, the present invention substantially improves the stress condition of the cantilever 2 and the upright post 1, and can reduce the possibility of structural damage.

In addition, the wind load mainly exists in the state when the signboard main body 3 is perpendicular to the wind direction, and in order to continuously improve the wind resistance performance of the present invention, the resistance of the signboard main body in the occurrence of the disastrous weather is improved to reduce the loss. The invention can also be used in such a way that the boom 2 and the signboard body 3 thereon are adjusted to a position non-perpendicular to the prevailing wind direction, i.e. the boom 2 is able to rotate a certain amount on the column 1 to adapt to changes in the wind direction.

The structure of the device can be that the cantilever 2 is connected with the upright post 1 through a risk avoiding angle adjusting seat 18. The cantilever 2 changes the angle on the upright post 1 through the danger avoiding angle adjusting seat 18 and forms rotation through the danger avoiding angle adjusting seat 18. As shown in fig. 7, the risk avoiding angle adjusting base 18 includes an i-shaped rotary cylinder 19 sleeved outside the vertical column 1, positioning discs 20 are respectively disposed on the vertical column 1 at the top and the bottom of the rotary cylinder 19, and the rotary cylinder 19 is clamped between the positioning discs 20. In order to facilitate the installation of the rotary drum 19, the lower positioning plate 20 is welded to the upright 1, and the upper positioning plate 20 is in threaded connection with the upright 1. When in use, the rotating cylinder 19 is sleeved on the upright post 1, and then the positioning disc 20 above is installed. As for the installation mode of the cantilever 2 on the rotary cylinder 19, the installation mode can adopt a mode that one end of the cantilever 2 close to the upright post 1 is provided with a sleeve 23 matched with the middle section of the rotary cylinder 19, the sleeve 23 is sleeved outside the rotary cylinder 19 and is fixedly connected with the rotary cylinder 19 through a locking bolt. It is also possible to weld the cantilever 2 directly to the rotary cylinder 19.

In the use process, the cantilever 2 should also have the resetting effect to ensure the support performance of the cantilever 2 in the normal use state and ensure the orientation of the cantilever 2 in the conventional condition. For this purpose, annular cavities 21 are further provided in the upper and lower ends of the rotary cylinder 19, and one surface of the cavity 21 facing the column 1 is provided with an opening. A reset torsion spring 22 is further arranged in the cavity 21, and the upper end and the lower end of the rotary drum 19 are connected with the upright post 1 through the reset torsion spring 22. When the cantilever 2 is adjusted in angle, the reset torsion spring 22 is twisted and stores elastic potential energy, and after the disaster-type weather is over, the reset torsion spring 22 drives the cantilever 2 to reset. Considering that wind has certain fluctuation, if the rotary drum 19 is in a free rotation mode, the cantilever 2 has the problems of too high swinging speed, frequent reciprocating swinging and the like. Therefore, the invention can also adopt a better design scheme that a compression rubber gasket is arranged on the end surface of the positioning disc 20 facing the rotary cylinder 19, and the damping sliding fit is formed between the positioning disc 20 and the end surface of the rotary cylinder 19 through the compression rubber gasket. The damping sliding fit is that the resistance to the rotation of the rotary cylinder 19 is increased by compressing the rubber pad, so that the cantilever 2 does not rotate too fast or too large during the swinging and resetting, but rotates slowly.

Finally, as shown in fig. 7, a buffer sleeve 24 is sleeved outside a section of the cantilever 2 close to the sleeve 23, the buffer sleeve 24 is in sliding fit with the cantilever 2, a buffer spring 25 is further sleeved outside the cantilever 2 between the buffer sleeve 24 and the sleeve 23, and two ends of the buffer spring 25 are respectively connected with the buffer sleeve 24 and the sleeve 23. Through designing buffer spring 25 and cushion collar 24, can carry out certain spacing to slip lantern ring 8 to prevent that signboard main part 3 from too much removing and causing the interference with stand 1 and relevant part.
