[0023] In describing the present invention, terms and words used in this specification and claims must be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0025] The device (1) of the invention is characterized by comprising: a body part (2) as shown in FIG. 1; a camera part (3) configured at the front end of the body part (2) for photographing the inside of a water pipe (P); a high-pressure water spray nozzle (4) configured at the front end of the body part (2) for spraying high-pressure water into the water pipe (P); a brush part (5) configured at the outer circumference of the body part (2) for removing foreign substances from the inner circumference of the water pipe (P); and a control module configured inside the body part (2) for controlling the camera part (3).

[0026] The device (1) of the present invention having the above configuration monitors the internal condition of the water pipe (P) while flowing inside the water pipe (P), and, based on the monitoring, flows to the part requiring cleaning and sprays high-pressure water, and cleans by removing foreign substances with a brush.

[0027] To this end, the device (1) of the present invention can be remotely controlled wirelessly, and can also be remotely controlled via a wired connection line in which an electric wire, etc., is embedded, although not shown in the drawing.

[0028] In addition, the device (1) of the present invention may be driven by a driving means, such as a propeller driven by a motor, although it is not shown in the drawings. Since various known technologies can be applied to such a driving means, a detailed description thereof is omitted.

[0029] The configuration of the device (1) of the present invention will be described in detail below.

[0030] The above body part (2) is configured to have various electrical devices, etc. built inside, and its material is not limited.

[0031] As shown in the drawing, the high-pressure water spray nozzle (4) is configured on the front of the body part (2) and allows high-pressure water to be sprayed into the water pipe (P) to perform cleaning. First, high-pressure water is sprayed to facilitate the removal of foreign substances deposited inside the water pipe, and then cleaning is performed by removing the foreign substances using the brush part (5) described below.

[0032] Although the high-pressure water spray nozzle (4) is not shown in the drawing, it may be configured to spray high-pressure water in conjunction with a high-pressure pump, and the high-pressure pump may be configured inside the body part (2) or outside the body part (2) so that a high-pressure water supply line is connected to the high-pressure water spray nozzle (4) to allow high-pressure water to be sprayed from the high-pressure water spray nozzle (4).

[0033] In addition, the device (1) of the present invention is provided with an embodiment that increases cleaning efficiency by simultaneously spraying high-pressure water and air as shown in FIG. 2.

[0034] To this end, an air supply line (8) that supplies air to the high-pressure water spray nozzle (4) while penetrating the body part (2) and a water supply line (9) in which one end of the body part (2) is exposed to the water pipe and the other end is connected to the air supply line (8) are further configured.

[0035] The air supply line (8) and the water supply line (9) are connected by a valve (V), and the valve (V) is opened and closed by the control of the control module (7).

[0036] Although not shown in the drawing, the air supply line (8) is connected to a high-pressure pump to supply high-pressure air, so that high-pressure air (a) is delivered to the high-pressure water spray nozzle (4). In this process, water (W) is supplied to the air supply line (8) through the water supply line (9) without separate power, so that high-pressure air (a) and water (W) are sprayed from the high-pressure water spray nozzle (4).

[0037] As shown in FIG. 4, the high-pressure water spray nozzle (4) is characterized by being composed of a protrusion (31) that protrudes from the front end of the body part (2) and has an air supply line (8) connected thereto, and a spray ring (32) that is mounted on the outer circumference of the protrusion (31) and includes a plurality of spray nozzles (321) in a ring shape and has the air supply line (8) connected thereto.

[0038] As mentioned above, high-pressure air (a) and water (W) are supplied to the injection ring (32) through the air supply line (8), and the high-pressure air (a) and water (W) supplied to the injection ring (32) are sprayed radially through a plurality of injection nozzles (321).

[0039] In addition, although not shown in the drawing, a structure in which the protrusion (31) or the spray ring (32) rotates may be applied so that rotational force is applied to the high-pressure air (a) and water (W) discharged through the spray nozzle (321) to further improve cleaning efficiency.

[0040] In addition, the camera unit (3) is configured to be connected to the front end of the above-mentioned protrusion (31) through an electric supply line (10).

[0041] The above camera unit (3) is not limited in type, but preferably, an acoustic camera, a hyperspectral camera, etc. are applied so that the internal condition can be accurately imaged even in cases where visibility is difficult to secure. The image data obtained by the camera unit (3) in this way serves as a basis for determining the necessity of cleaning or maintenance of the water pipe (P).

[0042] As shown in FIG. 6, image data from the camera unit (3) is transmitted to the control module (7), and the control module (7) transmits the image data to the central controller (12). The central controller (12) analyzes the condition of the water pipe (P) based on the transmitted image data. Here, the analysis may be performed based on the user's experience, but various AI modules may be applied to automatically analyze the condition of the water pipe (P).

[0043] The above control module (7) is configured inside the body part (2) and corresponds to a configuration that controls the camera part (3), the valve (V), etc., as shown in FIG. 2, in addition to the operating mechanism mentioned above.

[0044] This operating mechanism of the above control module (7) is designed to be operated by control from the above central controller (12).

[0045] As mentioned above, the control of the control module (7) by the central controller (12) can be remotely controlled by wired connection as well as by wireless connection.

[0046] The outer circumference of the above-mentioned body part (2) is characterized by having a plurality of gap openings (6) that maintain a gap with the inner circumference of the water pipe (P).

[0047] As shown in the drawing, the above clearance member (6) is configured to consist of an elastic bar that performs elastic recovery interlocking and a wheel at the end of the elastic bar, so that the body part (2) can operate by forming a certain clearance in the water pipe (P) through the elastic interlocking of the elastic bar according to the diameter of the water pipe (P).

[0048] The above elastic bar can be composed of an elastic material itself, and can generate an elastic restoring force by linking with a spring using a known structure.

[0049] The brush part (5) is configured to sweep along the inner circumference of the water pipe (P) to remove foreign matter.

[0050] Meanwhile, in the present invention, an embodiment for controlling the accumulation of foreign substances between the brushes of the brush section (5) and further increasing the efficiency of removing foreign substances by the brush is illustrated in FIG. 5.

[0051] The brush part (5) of the present embodiment is characterized by being configured to include a second injection ring (51) which is mounted on the outer circumference of the body part (2) and includes a plurality of second injection holes (511) in a ring shape and is connected to the air supply line (8), and a brush (52) protruding from the second injection ring (51).

[0052] By configuring it in this way so that high-pressure air (a) and water (W) are sprayed through the second nozzle (511) between the brushes (52), the accumulation of foreign matter between the brushes (52) is controlled, and the removal efficiency of foreign matter accumulated in the water pipe (P) is doubled by the abrasion by the brushes (52) and the impact by the spraying of high-pressure air (a) and water (W).

[0053] In addition, the present invention provides an example in which a filter member (11) is configured in the water supply line (9) as shown in FIG. 7. Foreign substances are mixed into the water inside the water supply pipe (P) due to cleaning by spraying air (a) and high-pressure water (W) in the water supply pipe (P) and cleaning by sweeping by the brush part (5). When such water is sucked in through the water supply line (9), the water supply line (9) and the air supply line (8) may be blocked by foreign substances. In this embodiment, water from which foreign substances have been filtered by the filter member (11) is introduced into the water supply line (9) and the air supply line (8).

[0054] The above filter member (11) is characterized by comprising a casing (111), a fixed mesh net (112) fixed to the front end of the casing (111), an interlocking mesh net (113) connected to the fixed mesh net (112) by a spring (114) to enable elastic recovery interlocking in the casing (111), and an elastic filter material (117) filled in the filling space formed by the fixed mesh net (112) and the interlocking mesh net (113).

[0055] The above casing (111) can be configured inside or outside the body part (2), and the drawing shows an example configured inside the body part (2).

[0056] The above casing (111) is configured in a water supply line (9) so that water from the water pipe (P) flows in through the water supply line (9) exposed at one end, and water that has been filtered by the operating mechanism described below is transferred to the air supply line (8) through the water supply line (9) connected at the other end of the casing (111).

[0057] The above fixed mesh (112) is configured to be fixed to the casing (111), and a receiving tube (115) is configured to protrude so that a spring (114) is contained within the central part, thereby allowing a part of the insertion tube (116) to be contained therein as described below.

[0058] The above interlocking mesh (113) is connected to the above fixed mesh (112) by a spring (114) and is configured to enable sliding interlocking on the inner circumference of the casing (111). The sliding interlocking of the above interlocking mesh (113) causes the volume of the filling space formed between the interlocking mesh (113) and the fixed mesh (112) to change.

[0059] In the above interlocking mesh (113), an insertion tube (116) is configured to protrude so that a spring (115) is contained within the central part, and the insertion tube (116) is slidably interlocked with the spring (114) while a part of it is contained within the receiving tube (115).

[0060] The spring (114) is mounted between the interlocking mesh net (113) and the fixed mesh net (112) while being contained within the insertion tube (116) and the receiving tube (115).

[0061] The above filter material (117) is made of an elastic material such as rubber, so that foreign substances deposited between the filter materials (117) can be easily removed by the elastic restoration of the filter material (117) itself.

[0062] As configured in this way, as seen in FIG. 8a, water (W) flowing into the water supply line (9) by driving the air supply line (8) is filtered as it passes through the filter member (11).

[0063] Although not shown in the drawing, the interlocking mesh (113) may be configured with a control jaw on the casing (111) so that the interlocking mesh (113) is controlled to slide in the direction of the fixed mesh (112) during the filtration process. That is, the volume of the filling space formed between the interlocking mesh (113) and the fixed mesh (112) is reduced to control the obstruction of water flow.

[0064] In such a process, if partial blockage occurs due to foreign matter (S) deposited between the filter materials (117), the valve (V) is actuated so that high-pressure air (a) is introduced into the filter material (11) through the water supply line (9) by the air supply means (8). As the pressure passing through the filter material (11) is increased by the air (a), the interlocking mesh (113) slides, and the filling space formed by the fixed mesh (112) and the interlocking mesh (113) becomes larger, thereby increasing the gap between the filter materials (117). Through this operating mechanism, the foreign matter (S) deposited in the filter material (117) is detached, and automatic cleaning is performed.

[0065] After washing is performed, the valve (V) is actuated to allow water to pass through the filter member (11). As the passing pressure decreases, the interlocking mesh (113) is restored to its original state, and the gap between the filter material (117) is also restored to its original state so that filtration is performed.

[0066] During this process, collisions occur between the filter materials (117). In this embodiment, the filter materials (117) are made of an elastic material to prevent damage to the filter materials (117) caused by collisions between the filter materials (117).

[0068] Although preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention.
