Technical Field

The invention relates to the technical field of road warning facilities, in particular to a warning cone capable of preventing dust and cleaning automatically.

Background

The road cone is also called as a traffic cone, is an obstacle for blocking road traffic, can be used as a barrier of a fence during road repair, is adhered with a high-strength reflective film, has a good reflective effect, plays a role in warning when placed on a road, is generally made of light materials and is arranged on a construction road section or under an emergency condition to prompt follow-up traffic flow to pay attention to avoidance;

Disclosure of Invention

The invention aims to solve the problem that traffic accidents are caused by the fact that the outer surface of a warning cone is easily polluted when the warning cone is arranged near a construction site and the reflection effect at night is reduced, and provides an anti-dust self-cleaning warning cone.

In order to achieve the purpose, the invention adopts the following technical scheme: the warning cone comprises a cone body and a base, wherein a cover plate is arranged at the top of the cone body, two connecting rods are symmetrically and fixedly connected in the cover plate and the base together, a layer of reflective film is arranged on the outer side of the cone body, a cavity is formed in the cover plate, an air inlet is formed in the inner wall of one side of the cavity and the outside in a penetrating mode, and an airflow channel is formed in the side wall of the cavity of the side far away from the air inlet;

the air flow channel is communicated with the outside and one end close to the outside is hermetically connected with sliding blocks, the sliding blocks are symmetrically arranged, each connecting rod is provided with one sliding block in sliding connection with the sliding block, the two sliding blocks are connected with a rubber lantern ring together, the rubber lantern ring is sleeved on the outer wall of the upper side of the cone, and bristles are fixedly connected to the rubber lantern ring;

the improved air inlet structure is characterized in that a piston is connected in the cavity, an air charging port penetrates through the piston, a one-way valve is hermetically connected in the air charging port, a rack is fixedly connected to one end, away from the air inlet, of the piston, a half gear is meshed with the rack, a rotating center of the half gear is fixedly connected with a rotating shaft, and the rotating shaft penetrates through the top wall of the cavity and is fixedly connected with a driving impeller outside the cover plate.

In the above-mentioned dustproof self-cleaning's warning awl, the recess of T type structure is seted up to the position that the cavity is located the piston, piston sealing sliding connection is in the recess, the lateral wall fixedly connected with a plurality of springs of piston near the air inlet, the other end fixed connection of spring is on the lateral wall that the piston was kept away from to the recess.

In the above-mentioned dustproof self-cleaning's warning awl, the junction of apron and slider is equipped with the magnetic layer, the slider adopts ferromagnetic material, the rubber lantern ring adopts silicon rubber materials.

Compared with the prior art, the invention has the advantages that:

1. according to the invention, the impeller is driven to rotate by the wind flow driven by the vehicle flow, and the piston in the cavity is driven to do reciprocating linear motion, so that the effect of inflating and applying pressure to one side is realized, when the air pressure value is greater than a certain degree, the sliding block is separated from the magnetic layer, and the rubber lantern ring and the bristles automatically clean the outer surface of the cone, so that the self-cleaning effect is realized;

2. in the specific process, when the external vehicle flow passes through or the external wind power is large, the driving impeller on the outer side of the cover plate is driven to rotate, so that the driving impeller drives the half gear to rotate through the rotating shaft, the rack and the piston are driven to slide towards one direction in a half period, and the piston is provided with the inflation channel and is connected with the one-way valve, so that the piston can press the gas on one side into the other side, and the air pressure in the cavity on the other side is increased;

3. meanwhile, the piston is fixedly connected with the spring, and in the other half period of the rotation of the half gear, the piston moves in the opposite direction under the compression action of the spring, so that the effect of introducing the outside air into the cavity is realized through the one-way valve of the air inlet, and the advantage is that when the outside vehicle amount continuously passes through, one side of the cavity is always inflated and pressurized;

4. the cavity on one side, which is pressed, is magnetically sealed on the other side through the magnetic layer and the sliding block through the air flow channel, when the air pressure is smaller than the magnetic attraction force, the sliding block is always sealed on the air flow channel, and when the air pressure is inflated to be larger than the magnetic attraction force, the sliding block is pushed to leave the bottom of the cover plate and has a larger downward acceleration under the action of compressed air, so that the rubber lantern ring is driven to integrally move downwards, and the inner side of the rubber lantern ring expands in the process from the top to the bottom of the cone, so that the effect of fully cleaning the outer surface of the cone is realized;

5. the rubber lantern ring is made of silicon rubber materials and has good heat resistance and elasticity, when the rubber lantern ring is arranged at the lower end of the cone, the rubber lantern ring has a tendency of shrinking inwards under the action of elastic restoring force of the rubber lantern ring, and the component force of the tendency on the surface of the cone is upward, so that the sliding block and the rubber lantern ring automatically move upwards for a period of time after moving downwards under the action of the shrinking elastic force of the rubber lantern ring, and are attracted at the position close to the magnetic layer of the cover plate, and the effect of restoring the initial state is achieved.
