Description

Technical Field

[0001] The utility model relates to the technical field of traffic facilities, in particular to a pedestrian crossing warning column. Background Art

[0002] With the development of technology, the process of urbanization is accelerating, and the popularization of transportation facilities has changed people's traditional travel methods while also bringing many negative effects, such as traffic congestion, increased traffic accident rates, etc. When pedestrians cross the street, they generally follow the instructions of traffic lights.

[0003] The prior art discloses a self-service intelligent pedestrian crossing warning column with application number CN202123351132.3 and a pedestrian crossing warning column with voice function with application number CN202022760868.5. The above two patents convert light energy into electrical energy through solar panels and store it in solar batteries, and then provide power to electrical appliances through solar batteries. However, since the warning columns are often set up on the roadside and there is a lot of dust due to the traffic, the dust is easy to adhere to the solar panels, thereby affecting their conversion. Exchange efficiency, and secondly, the warning column only serves as a reminder, but has no blocking function, which causes some uncivilized people to ignore the traffic lights and cross the road; further search found that the prior art discloses a light-controlled pedestrian crossing warning column CN202021968824.5. Although the warning column is provided with a barrier that can play a blocking role, since the barrier opens outward (towards the road), when the vehicle walking on the side does not brake in time, the barrier is easily hit, which will cause damage to both the vehicle and the barrier, and the safety factor is low. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a pedestrian crossing warning column to solve the technical problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pedestrian crossing warning column, comprising a base, a column body and a water collection tank being provided on the top of the base, the interior of the column body being connected to a gear via a rotating shaft, and a blocking rod being fixed to one side of the gear, a piston box and a motor being provided at the lower interior of the column body, and a lead screw being connected to the output end of the motor, a gear rod being provided on the outer surface of the lead screw, and a piston rod extending to the interior of the piston box being fixed to the bottom of the gear rod, a piston plate being fixed to the bottom end of the piston rod, a photovoltaic panel being provided on one side of the column body, and the photovoltaic panel being located above the water collection tank, the outer surface of the piston box being connected to the water collection tank via a pumping pipe, and a water supply pipe being connected to the back of the piston box.

[0006] Furthermore, an indicator light is provided on the outer surface of the column.

[0007] By adopting the above technical solution, the indicator light can switch between red, green and yellow lights at a regular time, thus achieving the purpose of directing traffic.

[0008] Furthermore, the outer surface of the barrier bar is provided with a plurality of equally spaced warning lights.

[0009] By adopting the above technical solution, the warning light can emit a warning light, thereby improving the eye-catching effect of the barrier.

[0010] Furthermore, the gear rod is threadedly connected to the lead screw, and the gear rod is meshed with the gear.

[0011] By adopting the above technical solution, the rotation of the screw rod can cause the gear rod to move, and the movement of the gear rod can cause the gear to rotate.

[0012] Furthermore, the water pipe is provided with a plurality of nozzles, and the nozzles are arranged to be inclined toward the photovoltaic panel.

[0013] By adopting the above technical solution, a plurality of nozzles can spray water evenly, thereby achieving the purpose of efficiently cleaning the photovoltaic panels.

[0014] Furthermore, a shielding cloth is connected between the blocking rod and the column.

[0015] By adopting the above technical solution, the shielding cloth can shield the movable opening of the barrier rod and prevent rainwater from entering the column.

[0016] Furthermore, a voice announcer is installed at the top of the column, a battery is installed on the upper part of the interior of the column, and the photovoltaic panel, motor, warning light and indicator light are all electrically connected to the battery.

[0017] By adopting the above technical solution, the photovoltaic panel can convert light energy into electrical energy and store it in the battery, and the battery can power the motor, warning light and indicator light.

[0018] Furthermore, solenoid valves are installed on the outer surfaces of the water delivery pipe and the water extraction pipe.

[0019] By adopting the above technical solution, the solenoid valve can control the direction of water flow in the water delivery pipe and the water extraction pipe.

[0020] Furthermore, a water guide plate and a filter screen are installed inside the water collecting tank respectively.

[0021] By adopting the above technical solution, the water guide plate plays a role in guiding rainwater, and the filter can filter impurities in sewage, thereby achieving the purpose of recycling rainwater.

[0022] In summary, the utility model mainly has the following beneficial effects: the utility model includes gears, toothed rods, screw rods, motors, piston boxes, water collection troughs, water pumping pipes and water delivery pipes. On rainy days, the water collection troughs can collect rainwater. When the red light prohibits driving, the motor rotates to rotate the screw rod, and the screw rod rotates to move the toothed rod upward. The gear drives the blocking rod to rotate counterclockwise to achieve the purpose of blocking driving. The upward movement of the toothed rod causes the piston rod to pull the piston plate to move upward in the piston box, so that water can be pumped into the piston box through the water pumping pipe. When the green light is released, the motor causes the screw rod to rotate. It rotates in the opposite direction, so that the gear rod moves downward, and the piston rod pushes the piston plate to move downward in the piston box, so that water can be sprayed out through the nozzle on the water pipe, thereby achieving the purpose of flushing and dust removal of the photovoltaic panel. The dust-removed water is filtered through the filter screen and returned to the sump for recycling. By regularly cleaning the photovoltaic panel, dust is prevented from adhering to the photovoltaic panel and affecting the conversion efficiency. The downward movement of the screw rod causes the gear to rotate in the opposite direction, so that the blocking rod moves upward, achieving the purpose of release. Since the blocking rod moves up and down, it will not cause collision with lateral vehicles, and the safety factor is high. BRIEF DESCRIPTION OF THE DRAWINGS
