Description

Technical Field

[0001] The invention relates to the technical field of underground garage traffic signs, and in particular to a self-cleaning underground garage traffic sign hanging device. Background Art

[0002] Underground parking lot signs refer to signs used to indicate the location of parking lots. Parking lot signs are divided into two categories based on whether they have arrows. One is a parking lot sign with an arrow, which means there is a certain distance between the parking lot and the parking lot sign, and the parking lot sign indicates the direction to the parking lot. The other is a parking lot sign without an arrow. This type of sign is placed in the parking lot to indicate that it is a parking lot. Speed ​​limit, height limit, no honking, no fireworks signs, exit signs, entrance signs, exit prohibited entry and other related signs will be installed above the road marking entrances and exits.

[0003] Most of the existing underground garage traffic signs are hung on the corresponding underground garage locations by simple steel wire ropes or screws. Although the traffic signs are fixed, they do not play an effective indicating role. In addition, they are often not cleaned in time due to their high installation position, and thus the meaning of the signs cannot be conveyed in time, resulting in some parking errors or risks.

The coil spring is fixedly installed in the collection groove by a pin, and the guide cavity is used to connect the collection groove with the cleaning mechanism.

[0008] Preferably, a magnet sheet is installed on one side of the wiper plate close to the mounting assembly through a screw thread, which is used to tightly adsorb the wiper plate on the traffic sign. A spray hole is provided on the side of the wiper plate close to the traffic sign, and the inner cavity of the wiper plate is connected to the inside of the worm through the bottom connecting plate and the clamping rod.

[0009] Preferably, the driving assembly includes a DD motor, which is embedded in the housing. A turbine is fixedly mounted on the output end of the DD motor, and the turbine is installed through the housing and the worm gear.

[0010] Preferably, a missing gear is meshed and installed on the side of the turbine away from the worm, and a rotating rod is fixedly connected to the middle of the missing gear. The missing gear is rotatably installed in the shell through the rotating rod, and the arc-shaped pull belt connected to the bottom of the disc spring is fixedly wrapped around the rotating rod.

[0011] Preferably, the cleaning mechanism includes a storage tank, which is embedded in the shell and has a one-way water inlet on its outer surface for directing the water guided by the guide cavity into the storage tank. A small pump is fixedly installed on the top of the storage tank, and an input pipe is fixedly connected to the top of the small pump. The top of the input pipe protrudes from the top of the shell, making it convenient to add cleaning liquid to the interior of the storage tank through the input pipe.

[0012] Preferably, a guide rod is fixedly connected to the outer surface of the storage tank, and a delivery hose is spirally wound on the outer surface of the guide rod, the bottom of the delivery hose is fixedly connected to the storage tank, and the top of the delivery hose is fixedly connected to the top of the worm.

[0013] Preferably, the mounting assembly includes at least two splints, which are mounted on both sides of the bottom of the shell through inlays, and the wiper is clamped and mounted between the two splints, and a hexagonal rod is inserted in the middle of the splint, and the splint is positioned and mounted on the bottom of the shell through the hexagonal rod.

[0015] The present invention provides a self-cleaning underground garage traffic sign hanging device, which has the following beneficial effects:

[0016] 1. The self-cleaning underground garage traffic sign hanging device can start a small pump to transport the cleaning liquid infused in the storage tank into the worm through a delivery hose. The cleaning liquid is then sprayed onto the surface of the traffic sign through the spray hole under the guidance of the clamping rod, the bottom connecting plate and the wiping plate. The DD motor drives the worm to reciprocate, so that the wiping plate combined with the cleaning liquid can quickly remove stubborn stains on the surface of the traffic sign, realizing the efficient cleaning function of the cleaning mechanism on the dust or stains on the surface of the traffic sign, without affecting the normal use of the traffic sign, preventing dust and stains from blocking the normal observation of the traffic sign by the parking personnel, ensuring that the relevant traffic information indicated by the traffic sign is correctly conveyed, and ensuring the safety of the parking personnel in the garage.

[0017] 2. The self-cleaning underground garage traffic sign hanging device can start the DD motor and, with the help of the meshing transmission between the missing gear and the turbine, drive the arc-shaped pull belt fixedly connected to the bottom of the coil spring to be wound around the rotating rod, thereby tightening the coil spring embedded in the collection tank and squeezing the moisture-absorbing cotton embedded on the inner side of the coil spring. When the turbine rotates to the position where the missing gear has no teeth, the coil spring can immediately rebound to its initial position, so that the moisture-absorbing cotton is fluffy again, which is convenient for repeated absorption of moisture in the air and realizes the reuse of the moisture-absorbing cotton. Through the above operation, the moisture in the humid air in the underground garage can be absorbed by the moisture-absorbing cotton, and the absorbed moisture is introduced into the storage tank through the water guided by the guide cavity, thereby realizing the recycling of water resources, which can not only remove part of the water vapor in the air in the underground garage, but also recycle and reuse the moisture in the humid air in the underground garage, and can assist in adding moisture to the storage tank.

[0018] 3. The self-cleaning underground garage traffic sign hanging device can start the DD motor, and through the meshing transmission of the turbine and the worm, it can drive the bottom connecting plate and the wiping plate connected to the bottom of the clamping rod to move, so that the wiping plate fits the surface of the traffic sign and moves from top to bottom, realizing automatic cleaning of dust on the surface of the traffic sign. In addition, through the magnetic attraction between the magnet sheet and the traffic sign, the wiping plate fits more closely on the surface of the traffic sign and wipes, thereby further improving the wiping force of the wiping plate on dust or stains and improving the cleaning efficiency of the cleaning mechanism.

[0019] 4. The self-cleaning underground garage traffic sign hanging device uses snap nails to fasten the traffic sign in the middle of the wiper between two plywood. The traffic sign can be quickly installed on the bottom of the lifting mechanism. While ensuring a stable installation between the traffic sign and the lifting mechanism, it is also convenient to quickly dismantle the traffic sign to replace other signs. If it is impossible to dismantle the workpiece specifically, the traffic sign can be dismantled and replaced manually. BRIEF DESCRIPTION OF THE DRAWINGS
