ROBOT FOR CLEANING DUCT HAVING THREE-WAY BRUSHES}

The present invention relates to a duct cleaning robot having a three-way brush, and more particularly, the brush in the duct cleaning robot for cleaning the foreign matter by the rotation of the brush while being moved into the duct for the purpose of air conditioning of the building. It is formed in three directions to provide tip propulsion to push or crush the foreign materials that block the direction of travel, and to prevent the screw from being easily released when the brush is rotated. A duct cleaning robot having an directional brush.

 A duct cleaning robot is a device for cleaning the inside of a duct which is generally buried in a predetermined position of a building and has a function of air conditioning. In the case of a duct, a plurality of pipes having a hollow structure are firmly connected to each other without air leakage. Since it has a basic installation purpose to be connected, it is not easy to separate and clean some parts. To solve this problem, it is directly injected into the duct and moved along the extension pipe to clean and remove foreign substances on the inner wall. Refers to a device that performs a function.

The duct cleaning robot is basically a body of a predetermined size is moved back and forth by the four drive wheels installed on the bottom, while the brush connected to the body to rotate the friction with the inner wall to filter the foreign matter through the suction pipe It consists of a structure and a way to inhale and temporarily store in the body.

In addition, these duct cleaning robots connect the body and the brush via a lift to rotate the brush within a certain angle so as to properly clean areas with large diameters or diameter differences in the duct, It is also equipped with a microphone to provide a convenience for the operator to conveniently control the driving state or progress state of the point where the brush is located, the body is conveniently located while visually and audibly detecting the situation in the duct.

Such a duct cleaning robot has already been published in a variety of domestic patents or utility model publications, Patent No. 188515 is equipped with a camera as well as a microphone to visually check the foreign matter in the duct to clean and at the same time It has a characteristic of picking up a large lump of foreign matter by the clamp means, and Patent No. 188515 allows the brush to be rotated at an angle and at the same time detects the position of the brush to make the brush rotation control to achieve a wider range. It has the feature of cleaning the site.

In addition, Patent No. 696866 provides the property that the cleaning robot can move regardless of the duct type by installing a monorail in the duct and moving the cleaning robot along this mono rail, and Utility Model Registration No. 139455 uses a camera and a brush. The height of the supporting frame is adjusted by the height adjusting means, thereby providing practicality that can be easily cleaned even in a duct whose height is not constant.

However, looking at the above technique, it can be seen that the brush is composed of a pair of left and right perpendicular to the moving direction and the transverse direction of the robot, according to the configuration of the brush, even if the contact probability that can contact the inner wall of the duct to the maximum It has the advantage that it can secure a wide range of cleaning, but if the foreign matter is not attached to the inner wall and is located directly in front of the robot body, it will not be cleaned properly and the tip of the body will move while dragging it. In addition to the problem, in addition, if the foreign matter has a certain level of weight or more, it may interfere with the smooth progress of the robot body, but it is inconvenient that it does not provide a way to solve it.

Referring to the domestic patent or utility model publication, it can be seen that some technologies are disclosed for the brush structure used in the duct cleaning robot, but Utility Model Registration No. 150963 is equipped with a sphere-shaped protective equipment on the brush end made of steel wire. It merely has the effect of preventing the iron wire from falling off when the brush rotates, and 150962 is provided with a groove having a predetermined shape in the brush body and coupling the pin to the brush body so that the brush does not leave the brush drive shaft when the brush rotates. It is not related to the problem of extending the cleaning radius of the brush, and Patent No. 540450 is an upper brush and a lower brush, which can simultaneously clean the ceiling, the floor, and the side wall of the duct in one movement of the body, thereby expanding the cleaning radius. While it can have a constant tip driving force, but the rotational force of either brush Since it is dependent on the other rotational force, not only the rotational force is relatively strong, but the direction of rotation and the direction of rotation are perpendicular to each other, so that the propulsion force by the rotational force, that is, the torque is relatively weak, allows the body to proceed smoothly despite foreign matters having a certain weight. There was a shortage in.

Therefore, the development of a new duct cleaning robot that prevents the problem that the main body stops in front of a certain weight or more in the duct by not only removing the foreign matter that exists around the moving direction of the robot body but also securing the tip driving force of the robot body more than a certain level.

In addition, the brush kits 21, 22, and 23 are composed of a coupling portion of the brush and the drive shaft.

As can be seen from Figure 2, the brush assembly 10 according to the present invention is three drive shafts (11, 12, 13) are connected to the gear assembly 14, respectively, the longitudinal direction of the body 80, namely The second and third drive shafts 12 and 13 extending in the first driving shaft 11 and the first driving shaft 11 in the right-angle direction, that is, the left and right directions extending laterally, respectively. It is called.

The first to third drive shafts 11, 12, and 13 are coupled to the first to third brush kits 21, 22, and 23, respectively.

Drive shafts (11, 12, 13) as a whole has a 'T' shape, as can be seen with reference to Figure 2, but by the rotation of the drive motor the first drive shaft basically receives the rotational force directly In order to transmit additional rotational force to the second and third drive shafts 12, 13, which are connected in a vertical direction, the present invention provides a gear assembly 14, for example, consisting of a combination of bevel gears connected in the vertical direction. .

Specifically, the bevel gear provided at the end of the first drive shaft 11 rotates while the bevel gears connected at right angles to both directions rotate together with the drive shaft 11 extending in three directions by the rotation of one drive motor. , 12, 13 can be rotated, and the gear assembly 14, which ensures such three-way rotational force, is not only a bevel gear assembly described above as an example, but also a gear assembly, for example, a worm, which is widely used in various fields. It is of course also possible to use such as gears or helical gear assemblies.

By this structure, the first to third brush kits 21, 22, and 23 connected to the first to third drive shafts 11, 12, and 13 also rotate to clean the inner sidewall of the duct (second, third brush). The functions of the kits (22, 23), as well as the driving force in the direction of progress, as well as cleaning the foreign matter stuck in the direction of progress (for example, floor, ceiling, floor and cupboard) (first brush kit ( 21) can provide usability.

3 is a side view showing a modification of the brush mounted to the first brush kit according to the present invention.

As described above, the brush of the first brush kit 21 also has a function of cleaning the foreign matter stuck in the progress direction, but it is also important to push or destroy the foreign matter blocking the progress direction so that the cleaning robot according to the present invention can proceed smoothly. .

To this end, the brush mounted on the first brush kit 21 is pointed than other brushes and needs to provide more enhanced tip propulsion. The brush of the first brush kit 21 according to the present invention has a sharp tip. It is preferable that the shape is configured to have the tip 21a.

In particular, the brush of the first brush kit 21 having the tip portion 21 provides a more useful role when foreign matter is gel-type or solidified to a certain level so that it is not pushed or disassembled only by the rotational force of the brush. You can do it.

Although not shown in the drawings, in addition to the brush mounted on the first brush kit 21 may be used to mount a larger diameter than other brushes, so that the floor and ceiling can be conveniently and conveniently cleaned at the same time.

Figure 4 is a cross-sectional view showing a coupling relationship of the coupling portion of the anti-loosening module and the brush kit according to the present invention.

In general, when the brush kits 21, 22, and 23 are connected to the drive shafts 11, 12, and 13, the brush is easily loosened from the drive shaft. In order to prevent this, the cleaning robot according to the present invention is prevented. Is provided with an anti-loosening module 30 at each end of each of the first to third drive shafts 11, 12, and 13, and correspondingly a groove 28 at the coupling end of the first to third brush kits 21, 22, and 23. ) Is provided with an engaging portion 27 mounted thereon, and an engaging portion provided with an O-ring 28 at the same time.

Specifically, the coupling portions of the brush kits 21, 22, and 23 are coupled portions 27 formed as predetermined lengths to serve as protrusions in a coupling relationship with the drive shafts of the brush kits 21, 22, and 23, and the coupling portions. O-ring 26 protruding in the form of a ring along the periphery of (27) and the depth of the engagement portion (preferably between the O-ring and the brush) surface of the engaging portion 27 is embedded in a predetermined depth, but the thread is mounted inside The groove 28 is provided.

Correspondingly, the anti-loosening module 30 has a larger volume than the first space 31 and the first space 31 that tightly receives the end of the coupling portion 27 and penetrates from the outside to the inside. It is comprised by the 2nd space 32 which is the space where the said O-ring 26 is accommodated in the state provided with the through-hole 33 formed.

The fastener P is a known coupling means such as a bolt or an anchor, and enters the second space 32 through the through hole 33 and finally engages with the groove 28 formed in the coupling portion 27.

The through holes 33 and the grooves 28 are preferably formed as two or more in total at regular intervals along the circumference of the forming site for the purpose of providing a stronger bonding force. If the two holes 33 and the groove 28 are formed as two, the holes 33 and the groove 28 are respectively opposite to each other (that is, one angle 180 degrees from the other) Formed on the opposite side helps to form a smooth bonding force.

According to this configuration, when the coupling portions of the brush kits 21, 22, and 23 are coupled to the anti-loosening module 30, the ends of the coupling portions 27 are tightly received in the first space 31, and the O-ring The 28 is located in the second space 32, and when the fastener P is coupled along the through hole 33 formed in the second space 32, the end of the fastener P reaches the groove 28. By the fastener P and the peripheral configuration, the resistance of the fastener P is primarily transmitted to the coupling portions of the brush kits 21, 22, and 23 and the anti-loosening module 30 to be rotated and transmitted. As the resistance is perpendicular to each other and the fasteners are rotated together with the rotation of the brush to prevent it from being separated, and secondly, even if the hanger brush kits 21, 22, and 23 are pushed in the longitudinal direction, as shown in FIG. Brush kits (21, 22, 23) no longer because Pushed in the longitudinal direction it is possible to prevent a phenomenon that exit from the drive shaft (11, 12, 13).

By the coupling part of the anti-loosening module 30 and the brush kits 21, 22, and 23, the brush is more firmly mounted to the drive shafts 11, 12, and 13, thereby providing a stable rotation state. do.
