Description

Outdoor signboard auto water cleaner around the road {omitted}

The present invention relates to a device capable of cleaning an outdoor signboard easily, quickly, and at a low cost, and can reduce the consumption of signboard electricity by reducing the illumination device used for a night signboard while being clean and clean.

As a conventional technique, there is a registered Korean Utility Model No. KR 20-0253305 Y1 (an automatic brush for water cleaning).
Signboards are installed in business places around the street, and the size of the signboard accounts for a large portion of the total area of the building. The installation cost of the signboard is heavy because it has been used for a number of years and the outdoor signboard is usually installed at the top of each floor of the building so it can be cleaned using a ladder car. There is an economic difficulty in cleaning the signboard.
Rain and outdoor signboards can be cleaned in rainwater, but only dust is removed in rainwater, and soot and stubborn foreign matter can not be removed and accumulated on the signboard. In addition, a large amount of lighting lamps must be installed to pass through a signboard stained with pollution, so power may be overpowered.

Even after cleaning the signboard, the water and detergent can not be collected and left in the surrounding area. Signboards made of protruding letters or moon-shaped signs on the signboard are more difficult to clean and continue to be used until the signboard disposal. And there is a problem that the comfort around the road is hindered.

In the present invention, a planar type flat roller (planar cleaning mop) and a circular type circular roller (circular cleaning mop) are integrally applied to clean a protruded surface of a signboard more easily than before, The planar roller and the circular roller are arranged so that the axes of the planar roller and the circular roller are perpendicular to each other, so that the efficiency of the operation is improved due to less swinging while cleaning the high place. It has an advantage that it can clean the signboard using the excellent action for collecting water and the rotation force of the deceleration motor for cleaning.

The present invention aims at recovering and processing the detergent constituents and water generated during cleaning of the signboard at a low cost in a short time and easy to clean the outdoor signboard. The circular roller is inserted into a narrow space between the protruding letters, The planar roller removes foreign substances on the protruding side of the letter, and the circular roller and the flat roller are simultaneously used, thereby improving the working efficiency.

This design is a device to clean outdoor signboard of a shop. It is made of high strength plastic rod (fishing rod) 250cm in length and 3cm in diameter using 3 pieces of rods. When 3 assembly rods are connected, it becomes 750cm in length. The waterproofing device includes a water collecting container, a hose fixing part, and a discharge hose. The water collecting device collects the detergent component and the wastewater generated during cleaning the signboard into the space of the rod.
A fixing plate is extended upward from the upper end of the assembly rod so as to prevent interference with the waterproofing device, and a roller and a cleaning water injector are sequentially connected to the fixing plate. The roller includes a rotating shaft that is connected to a planar roller and a circular roller in order and transmits rotational force to the flat roller while passing through the center of the flat roller, a circular roller coupled to one end of the rotating shaft, a first worm gear coupled to the other end of the rotating shaft, A second worm gear coupled to the iron rod at one end thereof, and a motor-driven deceleration motor (motor rotation shaft) coupled to the other end of the iron-core rod, wherein the motor rotation axis of the motor- And the second worm gear rotates the flat roller and the circular roller disposed horizontally by transmitting the power to the first worm gear. The first worm gear and the second worm gear are surrounded by the gear housing so that they are not exposed to the outside.

A cleaning water injector for spraying detergent and cleaning water on the top of the fixing plate of the assembly rod is connected to the inlet hose and the inlet hose is connected to the outlet of the high pressure water pump through the handle disposed at the lower end of the assembly rod, The cleaning bucket is connected so that water and detergent are supplied alternately to clean the signboard. Then, the power of the motor is supplied by the moving electric reel.

This design is based on the use of three high-strength plastic assembly rods for cleaning outdoor signage, a waterproofing device consisting of a double water catcher and drainage hose, a cleaning water sprayer for supplying detergent or water to the upper surface of the assembly rod, A high-pressure water pump and an inlet hose for supplying water, a flat roller and a circular roller provided at the intermediate point of the fixing plate of the assembly rod, a rotary shaft for transmitting a rotational force to the rollers, first and second worm gears, And a gear housing surrounding the first and second worm gears, the outdoor signboards installed at high places on the ground can be easily cleaned by persons who simply clean the signboards without using ladders or other equipment vehicles on the ground Device. In addition, it is possible to eliminate the inconvenience of the people who pass and pollute the surrounding environment by collecting the detergent and water discharged during the signboard cleaning.

The present invention will now be described in detail with reference to the accompanying drawings.
The assembly rods (1, 2, 3) are hollow type high strength plastic rods for forming and disassembling threads on the upper side and protrusions on the lower side to form threads on the outer surface of the protrusions, The waterproof rubber packing 4 is fitted to the protruding portion. A discharge hose (5, water hose) is provided at the upper end of the assembly rod, and the discharge hose is disposed at the valley portion of the water-bearing disposed at the lower end of the two water-
The cleaning water for cleaning the signboard is supplied alternately with the detergent and water in the water tank 19 and the cleaning water bottle 20 as needed and a high injection pressure is generated by the high pressure water pump 21, Is supplied along the thinner inlet hose 21 (hose tube) of the vinyl component connected to the outlet of the hose. (Not shown) is provided at the lower end of the assembly rod, and the end of the inflow hose is connected to the cleaning water injector 12 located at the upper end of the assembly rod. The cleaning water injected from the cleaning water injector 12 After cleaning the signboard, a discharge hose (5), which is collected by the two water tappers (6, 7) and connected to the lower end of the water receiver, is connected to the inside of the assembly rod to recover the cleaned water and detergent along the assembly rod The environment can be prevented from being contaminated.
As shown in FIG. 1, a fixing plate is fixed to the upper end of the assembly rod so as not to interfere with the discharge hose, and a double water receptacle 6, 7 is provided at the lower end of the fixing plate, Rollers 9 and 10 are connected to the center of the fixing plate, and a cleaning water injector 12 is connected in turn to the upper end of the fixing plate.
The roller has a rotation axis which is horizontally connected with the planar roller 9 and the circular roller 10 in order and transmits rotation force to the planar roller 9 through the center of the planar roller 9, The circular roller 10 and the first worm gear are coupled to both ends of the rotary shaft. And a second worm gear and a cleaning deceleration motor are provided at both ends of the iron rod, and the first worm gear and the second worm gear are coupled to each other in a tooth-like manner.
Therefore, when the motor rotation shaft of the cleaning deceleration motor rotates, the second worm gear coupled to the end of the iron core rod and the iron core rod coupled to the motor rotation shaft is rotated, and the rotational force of the second worm gear is transmitted to the first worm gear, 1 By rotating the rotary shaft connected to the worm gear, the planar roller and the circular roller can be rotated at the same time.
