Description

An Automatic Cleaning Device for Wall

The present invention relates to a wall automatic cleaning apparatus, and more particularly, to a wall automatic cleaning apparatus that performs a cleaning operation by automatically moving a wide wall surface such as a water purification plant or a low water storage space without requiring a cleaning operation by an operator, The cleaning tool is prevented from being insufficiently cleaned by being separated from the wall due to the vibration or repulsive force generated during the cleaning by performing the cleaning work in the state of firmly supporting the plurality of cleaning tools necessary for cleaning the wall, A plurality of cleaning operations are sequentially performed at a time when the cleaning module moves on a wall surface, thereby improving the efficiency of the wall cleaning operation.

Generally, when cleaning a wall surface of a sedimentation tank or a water tank in a water purification plant, high-pressure cleaning water is sprayed on a target wall surface to clean it. In this case, the sludge is adhered to the wall surface or the existing paint layer If present, the sludge or paint layer should be removed at the time of cleaning, and then the grinding and fading operations should be additionally performed.

For this purpose, in the prior art, the worker has manually performed the sludge removal operation, the grinding operation, and the high-pressure washing water injection operation manually. Therefore, the operation is very difficult due to the splashes of the washing water and the working dust, There is a problem that it can not be achieved.

In particular, since the wall of the settling tank or the water tank is generally high in height, it is necessary to use a ladder or a cleaning tool at an end of a long pole in order to clean the upper part of the wall surface. There has been a problem in that it may cause a safety accident of a worker.

Therefore, in order to solve this problem, a technique for performing the above-described operation using a cleaning device instead of the worker has been developed as in the following [1], but in the case of the technique according to the following [1] There is a disadvantage that the user has to move the apparatus directly in the workplace and thus the apparatus is still exposed to dust and the like.

In the case of the technique according to the following [Document 1], since the cleaning tool using the high-pressure washing water only has a structure of ascending and descending from the column-shaped platform, the repelling force generated when the high- There is a problem in that effective cleaning can not be performed because it is forced to be separated from the wall surface.

Further, in the case of the technique according to the following [Document 1], since the device is constituted so as to be capable of only cleaning, the cleaning, the sludge removal, the removal of the damaged layer, the drying of the washing surface, However, there is a problem in that work by the operator is still required or a separate working device must be provided.

In the automatic wall cleaning apparatus according to the present invention, the cleaning tool unit 20 is automatically moved on a wide wall surface by the cleaning tool moving unit 30 that can move up and down, right and left, It is not necessary to perform a dangerous cleaning operation by the operator, and the cleaning device is supported on the ground surface or the ceiling front surface or the flow preventive portion 40, which grips the upper end of the wall surface, Since the cleaning operation is performed in a state of firmly supporting the apparatus, the cleaning tool is separated from the wall surface due to vibration or repulsive force generated at the time of cleaning, thereby preventing insufficient cleaning, thereby remarkably improving the efficiency of the cleaning operation .

In addition, the wall surface automatic cleaning apparatus according to the present invention includes a plurality of cleaning means (22 to 27) required for cleaning the wall by one cleaning module in accordance with the operation order, so that when the cleaning module moves the wall, It is advantageous in that the efficiency of the wall cleaning work can be further remarkably improved.

For example, when cleaning means 22 to 27 are installed on the cleaning panel 21 in the same manner as in the present embodiment and work is performed in a zigzag form along the left-right direction and the up-down direction as shown in FIG. 3, If the scraping means 22 faces the wall W and the cleaning panel 12 moves from left to right, then moves downward in the vertical direction by a predetermined height and then moves from right to left, The grinding operation is performed by the grinding means 23 provided on the upper part of the scraping means 22 with respect to the cleaned surface on which the scraping operation has been performed previously.

[0030] The cleaning operation of the wall surface without the ceiling surface (i.e., the wall surface with the top open) using the automatic wall cleaning apparatus according to the present embodiment will be described. First, The lower supporting module 41 is operated to support the vehicle body 10 with respect to the ground surface G so that the bottom surface of the wheel 12 is separated from the ground surface do.

Thereafter, as described later, the wheel 12 is rotated in the direction of 90 degrees so that the apparatus can be moved to the next section along the left and right direction after the cleaning for the corresponding section is completed.

When the above steps are completed, the second hydraulic cylinder 42a and the third hydraulic cylinder 43a are operated to grip the upper end of the wall surface of the wall holding module 43, The cleaning tool moving unit 30 moves the cleaning tool unit 20 along the working direction (that is, in the above-described zigzag direction in this embodiment) to clean the cleaning tool moving unit 30 And perform the operation.

When the cleaning of the corresponding section (for example, the first section) is completed by the above-described method, the operation of the above-described flow preventing section 40 is released, and the next section (for example, the second section) The cleaning operation is performed in the same manner as the first section.

(Second Embodiment)

6 is a view for explaining a process of automatically cleaning a wall surface using the automatic wall cleaning apparatus according to the second embodiment of the present invention.

Since the second hydraulic cylinder 42a differs from the first embodiment only in the configuration of the second hydraulic cylinder 42a in this embodiment, the same constituent elements are denoted by the same reference numerals, and a duplicate description will be omitted.

The present invention relates to a wall surface automatic cleaning apparatus which is easy to apply when a wall surface is connected to a ceiling surface. In this embodiment, a wheel means 142c rotatable instead of packing is provided at the end of a second piston rod 42b, Is installed.

With the above-described structure, when the apparatus is moved to the next section after completion of the cleaning operation for any one of the sections, the wheel unit 142c rolls on the ceiling surface, so that the apparatus can be more smoothly moved.

In the meantime, although not described in detail in the present invention, in the case of the automatic wall cleaning apparatus according to the present invention, an additional hydraulic cylinder or a mechanical device may be added as needed so that the cleaning tool unit 20 rotates 90 degrees The present invention is not limited to the above embodiments, and various modifications and changes will be apparent to those skilled in the art.
