Technical Field

The invention relates to the technical field of building equipment, in particular to a self-cleaning type road sign for a building site.

Background

Bridge engineering or highway engineering's building site generally can span many roads, can be provided with various road signs that are used for instructing the road situation on these roads, instruction content on these road signs can help the driver to acquire near road condition fast, but because building site's dust is heavier, in addition have large freight train to transport the building materials to come and go for a long time, consequently often cover on these signs has more dust, the dust can shelter from instruction content on the sign, cause the driver of coming and going to be difficult for acquireing the road situation, not only lead to social vehicle mistake to go into the building site easily, cause unnecessary danger, still lead to building materials transportation driver easily and can't in time transport building materials to needs the position because of being unfamiliar with the road condition.

For dust on the indication board, special persons are usually arranged regularly for cleaning by related personnel on a building site, but the indication board is generally high in height, so that the personnel are required to climb to the top of the upright post rod during cleaning, the indication board is cleaned in a suspension mode, operation is troublesome, certain potential safety hazards exist, and the cleaning personnel can influence a driver to obtain indication content of the indication board during cleaning; and because this type of building site is striden regional great, this type of sign quantity is a lot of, therefore cleaner once need clean more sign, and intensity of labour is very high.

Disclosure of Invention

The invention aims to solve the defects in the prior art, and provides a self-cleaning type road sign for a construction site, which can realize automatic cleaning and dust removal of the surface of the sign by arranging an impeller, a permanent magnet, a telescopic air bag, an air outlet mechanism, a spiral coil and an indication lamp bar, avoid the shielding of dust on indication contents, enable a driver to clear and master road conditions, reduce the occurrence probability of traffic accidents at the position, and simultaneously avoid manual cleaning, thereby not only avoiding the potential safety hazard of manual cleaning, improving the cleaning efficiency and reducing the labor intensity, but also enabling the indication lamp bar to emit light when the impeller rotates to enhance the warning effect of the road sign, better helping the driver to obtain the indication contents, attracting the attention of the driver and enabling the driver to more actively watch the sign to obtain the road conditions.

In order to achieve the purpose, the invention adopts the following technical scheme:

a self-cleaning road sign for construction sites comprises a stand column rod and a sign fixedly connected to the side wall of the stand column rod through a fixing plate, wherein a device cavity is formed in the side wall of the stand column rod, the side wall of the upper end of the stand column rod is rotatably connected with an impeller through a rotating shaft, the rotating shaft extends into the device cavity and is fixedly connected with a permanent magnet, a magnetic sliding plug is connected in the device cavity in a sealing and sliding manner below the permanent magnet, a sealing plate is fixedly connected in the device cavity in a sealing manner below the sliding plug, a telescopic air bag is fixedly connected to the lower end of the sealing plate and is communicated with the space above the sealing plate, a plastic part is fixedly connected to the lower end of the telescopic air bag, a sliding groove is formed in the lower end of the plastic part, an air outlet communicated with the telescopic air bag is formed in, the air outlet mechanism is used for completely discharging air in the telescopic air bag when the telescopic air bag expands to a certain degree, an air cavity communicated with the lower end part of the device cavity is formed in the side wall of the fixing plate in the vertical direction, and air nozzles communicated with the air cavity are formed in the side wall of the fixing plate in front of the indicator.

Preferably, the air outlet mechanism comprises a sealing block and a magnetic block, the sealing block is connected to the top in the sliding groove in a sealing and sliding mode, the magnetic block is fixedly connected to the lower end portion of the inner wall of the cavity of the device, the sealing block is elastically connected with the inner wall of the sliding groove through a spring, damping exists between the sealing block and the top in the sliding groove, and the sealing block is magnetic.

Preferably, the outer ring of the permanent magnet is provided with a plurality of turns of spiral coils in a closed state, the periphery of the indication content on the indication board is provided with indication lamp bars, and the indication lamp bars are coupled with the spiral coils.

The invention has the following beneficial effects:

1. through the arrangement of the impeller, the permanent magnet, the telescopic air bag, the sliding plug, the sealing plate, the air cavity and the exhaust port, the impeller can be driven by wind power to rotate, so that the permanent magnet is driven to rotate, the sliding plug is driven to move up and down, air is continuously pumped into the telescopic air bag, after the impeller rotates for a plurality of circles, gas stored in the telescopic air bag can be sprayed out at high speed and enters the air cavity, and finally the gas is sprayed onto the surface of the indicator from the gas spraying port, so that dust on the mirror surface is blown off, the situation that the driver cannot easily obtain road conditions due to the fact that the;

2. by arranging the telescopic air bag, the air outlet mechanism and the magnetic block, when the telescopic air bag expands until the sealing block is flush with the magnetic block, the magnetic block pushes the sealing block away from the air outlet, when the sealing block loses repulsion force of the magnetic block to push, the sealing block can slowly slide under the action of spring force, the air outlet can be sealed again after a period of time, and air in the telescopic air bag can be completely discharged within the period of time, so that sufficient air flow at an air outlet is ensured, and the effect of fully removing dust on the surface of the indicator is achieved;

3. the air jet is arranged in a shape of inclining towards the surface of the indication board, so that certain radial force can be generated on the surface of the indication board 2 by air flow sprayed from the air jet 11, and dust adhered to the surface of the indication board can be blown off together, so that the dust removal effect is better;

4. by arranging the impeller, the permanent magnet, the telescopic air bag, the air cavity and the air jet, the self-cleaning of the indicator can be realized, a specially-assigned person does not need to climb to the upright post rod to clean the indicator manually, the labor intensity is reduced, the potential safety hazard existing when the specially-assigned person climbs in a cleaning mode is avoided, and meanwhile, the self-cleaning of each indicator can be realized by arranging the device on each indicator, so that the cleaning efficiency can be greatly improved;

5. through setting up helical coil, instruct the lamp strip, permanent magnet and impeller, can be when the impeller is driven and then drive the permanent magnet and rotate by wind-force, make helical coil can cut the magnetic induction line of permanent magnet, thereby make induced-current production on the helical coil, make instruct lamp strip circular telegram luminous, not only can help the driver to obtain instruction content better, can also attract driver's attention, make the driver more initiative watch the sign in order to obtain the road condition, prevent that the driver from not noticing the sign when driving, thereby missed instruction content.
