Description

Technology Field

[0001] The present invention relates to a water pipe non-disruption imaging system, and more specifically, to a water pipe non-disruption imaging system capable of inspecting the internal space of a water pipe through which fluid flows by imaging without interruption, capable of imaging while advancing the imaging device tens of meters to tens of kilometers or more in the water pipe, and capable of selectively and easily withdrawing the imaging device at a desired point after inserting the imaging device into the internal space of the water pipe. Background Technology

[0003] In general, various pipes carrying fluids, such as water pipes, undergo deterioration over time due to factors like scale buildup and internal corrosion, which can lead to pipeline accidents such as pipe breakage. Therefore, it is crucial to regularly inspect and diagnose the interior of the pipes to maintain and repair them as necessary.

[0004] Traditionally, maintenance and repair of piping involved shutting off the fluid flow to empty the pipes before inspecting the interior; however, because this traditional method causes significant adverse effects due to the water cutoff, non-stop water inspection methods, which allow for pipe inspection without interrupting the fluid flow, are now primarily used.

[0005] As can be seen in registered patent No. 10-0989067, this conventional non-disruption method involves attaching a camera to the end of a cable that can be inserted into the pipe, and inspecting the inside of the pipe by moving the camera along the pipe to photograph it.

[0006] However, cameras used in conventional non-disruption methods have a problem in that they cannot film the entire interior of the pipe because they are dragged along one wall, such as the bottom of the pipe, due to the weight of the camera inserted into the pipe.

[0007] Furthermore, in conventional methods, cameras only capture a specific area of ​​the piping rather than the entire surface, which means that the manager cannot view the entire interior of the piping—the most critical aspect for inspection—and thus cannot accurately diagnose the internal condition of the piping.

[0008] In addition, in the case of conventional water pipe imaging technology, a camera is inserted at a specific point within the water pipe. The camera moves along the internal space of the pipe, propelled by the fluid flowing through it, and films the interior of the pipe.

[0009] Then, once the filming work is completed, the camera is retrieved from the insertion point of the water pipe. The retrieval method used is winding the connecting cable attached to the camera. However, the fluid flowing through the internal space of the water pipe flows at a high velocity. Consequently, the camera experiences strong resistance from the fluid during the retrieval process. Due to this, conventionally, the camera was moved only a short distance of about 20m to 30m inside the water pipe before being retrieved, which required a significant amount of time to film the internal space of the water pipe. Furthermore, there is the cumbersome and inconvenient problem of having to shut off the water supply to retrieve the camera. Prior art literature

[0011] Registered Patent Publication No. 10-0989067 The problem to be solved

[0012] The present invention has been devised to solve the problems of the aforementioned prior art, and aims to provide a water pipe non-stop inspection system that allows an imaging device to be easily inserted into the internal space of a water pipe through any one selected from a splitter tube, an air valve, a saddle, and an inspection port, and enables the internal space of a water pipe through which fluid flows to be inspected by imaging without interrupting the water supply.

[0013] In addition, by applying a selective separation method between the imaging device and the connecting cable, the imaging device and the connecting cable inside the water pipe can be withdrawn to the outside at different points, and in particular, the imaging device can be withdrawn without resistance from the fluid flowing through the internal space of the water pipe, thereby enabling the imaging device to be advanced for tens of meters to tens of kilometers or more within the internal space of the water pipe while taking pictures. This relates to a water pipe non-stop imaging system. means of solving the problem

[0015] A water pipe non-disruption imaging system according to one embodiment of the present invention comprises: an input guide unit set in the internal space of a water pipe; an imaging unit guided by the input guide unit and inserted into the internal space of the water pipe, and then moving along the water pipe by a flowing fluid to perform imaging; and an extraction unit applied to the water pipe, positioned at a predetermined distance from the input guide unit, and configured to extract the imaging unit inserted into the internal space of the water pipe to the outside.

[0016] And, the above-mentioned input guide part includes an input pipe part that is mounted on the water pipe and whose interior is connected to the interior space of the water pipe; a receiving pipe part that is received in the interior space of the input pipe part and has an input passage formed therein for inserting the imaging part; and a first direction change part that is connected to one side of the receiving pipe part, is received in the interior space of the sewer pipe, and is formed in a curved shape to change the direction of movement of the imaging part moving along the input passage to the direction of fluid flow.

[0017] Additionally, the above-mentioned imaging unit is mounted thereon, and the buoyancy unit is formed in a streamlined shape to allow movement while floating due to the fluid present in the internal space of the water pipe; and at least one propeller is installed on the buoyancy unit and rotates by the power of a motor.

[0018] And, the above-mentioned extraction member comprises: an extraction pipe section that is mounted on the water pipe and is positioned at a certain distance from the insertion guide section, and whose interior is connected to the interior space of the water pipe; an additional receiving pipe section that is received in the interior space of the extraction pipe section and has an extraction passage formed therein for extracting the imaging section; and a second direction changing section that is connected to one side of the extraction pipe section and is formed in a curved shape to change the direction of movement of the imaging section, which is received in the interior space of the water pipe and has moved along the interior space of the water pipe, toward the extraction passage.

[0019] Additionally, the apparatus further comprises: a connecting cable connected to the above-mentioned imaging unit and including a first connecting section and a second connecting section connected to the first connecting section; first and second connectors each mounted on the first connecting section and the second connecting section, detachably coupled to each other, and electrically connecting the first connecting section and the second connecting section when coupled to each other; and a separating unit that separates the first connector and the second connector before withdrawing the above-mentioned imaging unit.

[0020] And, the separation unit includes a first gear unit applied to the first connector or the second connector side; a second gear unit engaged with the first gear unit; and a rotary drive unit that rotates the second gear unit so that the first connector and the second connector are separated. Effects of the invention

[0022] The water pipe non-stop imaging system according to the present invention has the effect of easily inserting an imaging device into the internal space of a water pipe through any one selected from a splitter tube, an air valve, a saddle, and an inspection port, and being able to inspect the internal space of a water pipe through which fluid flows by imaging without interrupting the water supply.

[0023] In addition, by manufacturing the buoyancy unit in a submersible or streamlined shape so that it moves smoothly while floating due to the fluid present in the internal space of the water pipe, it is possible to accurately photograph the interior of the water pipe with the camera unit.

[0024] In addition, the first connector and the second connector can be automatically separated within the internal space of the water pipe, and by connecting the imaging unit to the first connector, the connecting cable is retrieved at the point of insertion of the imaging unit. Since the imaging unit, which experiences more fluid resistance than the connecting cable, is withdrawn at a desired location in the direction of fluid flow, it has the effect of enabling imaging while moving the imaging unit within the internal space of the water pipe for tens of meters to tens of kilometers.

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Throughout the specification, similar parts are denoted by the same reference numerals.

[0030] FIG. 1 is a diagram illustrating an example in which a water pipe non-stop shooting system according to an embodiment of the present invention is applied to the internal space of a sewer pipe; FIG. 2 is a cross-sectional view illustrating the combined state of a shooting unit, a buoyancy unit, a first connecting section, and a propeller applied to a water pipe non-stop shooting system according to an embodiment of the present invention; FIG. 3 is a diagram illustrating the process of withdrawing the shooting unit and the buoyancy unit applied to a water pipe non-stop shooting system according to an embodiment of the present invention through a withdrawal unit; and FIG. 4 is a cross-sectional view illustrating the combined state of a first connector, a second connector, and a separation unit applied to a water pipe non-stop shooting system according to an embodiment of the present invention.

[0031] A water pipe non-stop shooting system (1) according to one embodiment of the present invention can inspect the internal space of a water pipe (2) through which fluid flows by shooting without interruption of water flow, and in particular, can easily insert a shooting device into the water pipe, shoot while advancing the shooting device from tens of meters to 1.2 km or more in the water pipe (2), and can easily withdraw the shooting device at a desired point.

[0032] To this end, a water pipe non-disruption imaging system (1) according to one embodiment of the present invention may include at least one of an input guide unit (10), an imaging unit (20), a buoyancy unit (40), a connecting cable (60), a first connector (70), a second connector (80), a separation unit (100), and an extraction unit (30).

[0033] The insertion guide section (10) is set in the water pipe (2) and is configured to guide the shooting section (20) to be smoothly inserted into the internal space of the water pipe (2).

[0034] The input guide section (10) includes an input pipe section (11) and an input section (12).

[0035] The input pipe section (11) is installed on the outer surface of the water supply pipe (2).

[0036] Typically, the water pipe (2) is equipped with a drainage pipe, air valve, saddle, inspection port, etc.

[0037] In a water pipe non-stop shooting system (1) according to one embodiment of the present invention, the input pipe section (11) can be selectively applied to one or more selected from a fixed pipe, an air valve, a saddle, and an inspection port that are coupled to the water pipe (2).

[0038] At this time, the input pipe section (11) is applied to any one of the following selected by the worker: a fixed pipe, an air valve, a saddle, or an inspection port.

[0039] Typically, a connecting member (3) is formed in the water supply pipe (2) to which a connecting pipe or an air valve is bolted. The connecting member (3) is formed with a structure having an empty space formed inside.

[0040] A flange portion (3a) is formed in the connecting member (3).

[0041] A flange portion (not shown) is formed in the slit tube or air valve to be bolted to the flange portion (3a) of the connecting member (3).

[0042] Therefore, the air valve or air valve can be separated from the flange portion (3a) of the coupling member (3), and then the input tube portion (11) can be applied to the coupling member (3).

[0043] In the input pipe section (11), an internal space (11a) is formed that is connected to the internal space of the connecting member (3) and the internal space of the water pipe (2).

[0044] Additionally, the flange portion (3a) includes a hollow that is connected to the internal space of the connecting member (3). Thus, the lower portion of the input pipe portion (11) can be connected to the internal space of the connecting member (3).

[0045] Additionally, a spiral is formed on the outer circumference of the input pipe section (11), and a spiral is formed on the inner circumference of the connecting member (3) to which the spiral of the input pipe section (11) is fastened, so that the input pipe section (11) can be connected to the connecting member (3) in a spiral fastening manner.

[0046] As another example, it is also possible to form the size of the input pipe section (11) larger than the size of the connecting member (3) so that the input pipe section (11) wraps around the outer circumference of the connecting member (3).

[0047] In such a case, a spiral may be formed on the inner circumference of the input pipe section (11), and a spiral to which the spiral of the input pipe section (11) is fastened may be formed on the outer circumference of the coupling member (3), thereby connecting the input pipe section (11) to the coupling member (3) in a spiral fastening manner.

[0048] Meanwhile, if you want to apply the input tube (11) to the saddle, you can drill a hole in the saddle and then insert the input tube (11) into the hole.

[0049] And, after performing the shooting operation, you just need to bolt a separate plug to the saddle to close the hole.

[0050] Meanwhile, the input section (12) includes a receiving section (121) and a first direction change section (122).

[0051] The receiving tube section (121) is received in the internal space (11a) of the input tube section (11).

[0052] At this time, a spiral (not shown) that is connected to each other is formed along the length direction on the inner circumference of the input pipe section (11) and the outer circumference of the receiving pipe section (121). As a result, the receiving pipe section (121) can be easily connected to the input pipe section (11) in a spiral manner.

[0053] An insertion passage is formed inside the receiving pipe section (121) to insert the imaging section (20) and the buoyancy section (40). The imaging section (20) and the buoyancy section (40) are inserted into the internal space of the water pipe (2) by sequentially passing through the insertion passage of the receiving pipe section (121) and the first direction change section (122).

[0054] The first direction changing unit (122) is formed on one side of the receiving pipe unit (121) and is received in the internal space of the sewer pipe (2). The first direction changing unit (122) is formed in a curved shape so as to smoothly change the direction of movement of the shooting unit (20) and the buoyancy unit (40) descending along the input passage to a horizontal direction, that is, the direction of flow of the fluid flowing along the internal space of the water pipe (2).

[0055] The shooting unit (20) descends along the input guide surface (121) and is guided by the inclined surface (122) to change direction. The shooting unit (20) can be moved to the shooting direction (A) after changing direction. At this time, the shooting direction (A) is the direction of fluid flow along the internal space of the water pipe.

[0056] The shooting unit (20) is guided by the input guide unit (10) and inserted into the internal space of the water pipe (2), and then moves along the water pipe (2) by the flowing fluid to perform shooting.

[0057] The shooting unit (20) can be formed as a camera or an endoscope.

[0058] The camera unit (20) is inserted into the internal space of the water pipe (2) while connected to the connecting cable (60) and films the internal space and inner circumference of the water pipe (2).

[0059] The camera unit (20) may include a lighting device to effectively photograph the interior space of the dark water pipe (2).

[0060] The image of the internal space of the water pipe (2) captured by the camera unit (20) is transmitted to a manager PC located on the ground. Therefore, the manager can accurately check the internal condition of the water pipe (2) through the image displayed on the monitor of the manager PC.

[0061] The buoyancy unit (40) is configured to have the shooting unit (20) mounted thereon.

[0062] A fixing groove (40a) is formed on the front side of the buoyancy part (40) to which the shooting part (20) is fixed.

[0063] The shooting unit (20) can be accommodated in the fixing groove (40a) such that only the lens (21) protrudes outside the buoyancy unit (40).

[0064] And, a connection hole (40b) is formed inside the buoyancy part (40). A part of the connection cable (60), which will be described later, is received in the connection hole (40b). And, one end of the connection cable (60) received in the connection hole (40b) is electrically connected to the imaging part (20) on the fixing groove (40a).

[0065] The buoyancy part (40) can be formed of a material having buoyancy so as to be floated by the fluid present in the internal space of the water pipe (2).

[0066] For example, the material of the buoyancy part (40) can be formed from any one of polyethylene, silicone, synthetic resin, and metal materials.

[0067] It is revealed that the material of the buoyancy part (40) in the water pipe non-disruption imaging system (1) according to one embodiment of the present invention is not limited to polyethylene, silicone, synthetic resin, or metal, and can be replaced with any one of various materials having buoyancy.

[0068] When the buoyancy part (40) is buoyed by a fluid, the pressure intensity of the water pipe (2) is typically stronger in the central region than at the edge of the internal space of the pipe.

[0069] Accordingly, the water pipe non-disruption imaging system (1) according to one embodiment of the present invention can ensure that the buoyancy part (40) and the imaging part (20) are always positioned in the central area of ​​the internal space of the water pipe (2) without being deviated to one side, such as sinking to the bottom surface of the water pipe (2), through the aforementioned principle.

[0070] In addition, the buoyancy unit (40) and the camera unit (20) are floated in the central area of ​​the internal space of the water pipe (2) and move along the internal space of the water pipe (2) by the flow of fluid, thereby capturing the entire internal space and inner periphery (inner wall surface) of the water pipe (2). As a result, the entire internal space of the water pipe (2) can be captured without any blind spots.

[0071] In particular, the buoyancy part (40) is formed in a submersible shape or a streamlined shape so that it can move smoothly while floating due to the fluid present in the internal space of the water pipe (2).

[0072] At least one propeller (50) is installed in the buoyancy section (40).

[0073] The propeller (50) is configured to prevent the phenomenon in which the buoyancy part (40) and the camera part (20) mounted on the buoyancy part (40) sink to the bottom surface of the water pipe (2).

[0074] The propeller (50) can be installed on at least one of the upper, lower, left, right, and rear sides of the buoyancy part (40).

[0075] At this time, the propeller (50) may be installed on at least one of the upper side, lower side, left side, right side, and rear side of the buoyancy part (40).

[0076] In addition, at least one propeller (50) may be installed on each of the upper, lower, left, right, and rear sides of the buoyancy part (40).

[0077] For example, the propeller (50) can be installed so as to be exposed to the outside of the buoyancy part (40).

[0078] As another example, the propeller (50) can be installed so as to be concealed inside the buoyancy part (40).

[0079] To this end, a concealment groove is formed in the buoyancy part (40) in which a propeller (50) is concealed.

[0080] The propeller (50) can be rotated by the motor (51) while hidden in the concealed groove.

[0081] Since the motor (51) may come into contact with the fluid flowing through the internal space of the water pipe (2), it can be waterproofed. By wrapping the outer surface of the motor (51) with a waterproof cover (not shown) or attaching a waterproof pack (not shown) to the motor (51), the phenomenon of the motor (51) coming into contact with the fluid can be prevented.

[0082] A connecting cable (60) described later is connected to the shooting unit (20) mounted on the buoyancy unit (40), and the connecting cable (60) is gradually introduced into the internal space of the water pipe (2) by a worker located on the ground. Accordingly, when the propeller (50) is rotated by the motor (51), rather than generating propulsion force on the buoyancy unit (40), it prevents the buoyancy unit (40) and the shooting unit (20) mounted on the buoyancy unit (40) from sinking to the bottom surface of the water pipe (2).

[0083] At this time, after the second connecting section (62) of the connecting cable (60) described later is separated from the buoyancy section (40), the buoyancy section (40) is drawn out to the outside of the water pipe (2) through the extraction section (30) described later, and the propeller (50) generates thrust only when drawing out the buoyancy section (40). The method of drawing out the buoyancy section (40) by the propeller (50) will be explained in detail later when describing the connecting cable (60) and the separation section (100).

[0084] Additionally, an additional concealment groove may be formed on the bottom surface of the buoyancy part (40), and another propeller may be installed in the additional concealment groove. The other propeller is installed to face the bottom surface of the water pipe (2). The other propeller is rotated by a motor to prevent the buoyancy part (40) from sinking to the bottom surface of the water pipe (2).

[0085] At this time, other propellers and other motors may be exposed to the lower side of the buoyancy section (40). In this case, the motor may be coupled to the bottom surface of the buoyancy section (40).

[0086] The motor (51) for rotating the propeller (50) can be controlled by an operating device formed by a control panel located on the ground or a remote control.

[0087] The operating device is provided with a first-1 button for rotating the drive shaft of the motor (51) in the forward direction, a first-2 button for rotating the drive shaft of the motor (51) in the reverse direction, and an on / off button for supplying or cutting off power to the motor (51).

[0088] Since the propeller (50) and motor (51) are applied in multiple numbers to the buoyancy unit (40), the first button, the second button, and the on / off button are applied in the same number as the motor (51).

[0089] Additionally, the buoyancy height of the buoyancy unit (40) and the shooting unit (20) can be adjusted through the propellers (50).

[0090] A worker located on the ground can selectively operate the motor (51) positioned on the upper and lower sides of the buoyancy unit (40) to lower or raise the buoyancy unit (40).

[0091] When the buoyancy unit (40) is lowered, the camera unit (20) gets closer to the bottom surface of the water pipe (2), so the bottom surface of the water pipe (2) can be photographed more accurately.

[0092] And, when the buoyancy unit (40) is raised, the camera unit (20) gets closer to the ceiling surface of the water pipe (2), so the ceiling surface of the water pipe (2) can be photographed more accurately.

[0093] In addition, the left and right positions of the buoyancy unit (40) and the shooting unit (20) can be adjusted through the propellers (50).

[0094] A worker located on the ground can selectively operate the motors (51) positioned on the left and right sides of the buoyancy unit (40) to move the buoyancy unit (40) to the left or right.

[0095] When the buoyancy unit (40) is moved to the left, the camera unit (20) gets closer to the left wall of the water pipe (2), so the left wall of the water pipe (2) can be photographed more accurately.

[0096] And, when the buoyancy unit (40) is moved to the right, the camera unit (20) gets closer to the right wall of the water pipe (2), so the right wall of the water pipe (2) can be photographed more accurately.

[0097] The connecting cable (60) can be formed as a conventional electric cable that supplies power to the shooting unit (20).

[0098] The connecting cable (60) includes a first connecting section (61) that is electrically connected to a connection terminal (not shown) provided in the shooting unit (20), and a second connecting section (62) that is connected to the first connecting section (61).

[0099] And, the first connecting section (61) is mounted on the first connector (70) and the second connecting section (62) is mounted on the second connector (80), and as the first connector (70) and the second connector (80) are connected, the first connecting section (61) and the second connecting section (62) are electrically connected.

[0100] The connecting cable (60) can be applied as a standard buoyancy cable or a submarine cable.

[0101] A winding machine for winding or unwinding the second connecting section (62) is positioned on the ground, and the filming unit (20) is inserted into the internal space of the water pipe (2) via the insertion guide unit (10) as the winding machine unwinds the second connecting section (62).

[0102] At this time, the winding device may be omitted, and in such a case, the connecting cable (60) may be manually inserted into the internal space of the water pipe (2) by a worker located on the ground.

[0103] Meanwhile, the filming unit (20) inserted into the internal space of the water pipe (2) moves along the water pipe (2) by the flow of fluid flowing through the internal space of the water pipe (2) and films, and the movement of the filming unit (20) is led by the buoyancy unit (40).

[0104] The first connector (70) is mounted on one side of the first connecting section (61).

[0105] The second connector (80) is mounted on one side of the second connecting section (62).

[0106] The first connector (70) and the second connector (80) can electrically connect an electric cable and can be applied as any one of the waterproofed conventional connector products.

[0107] The first connector (70) includes a first locking nut (71) through which a certain area of ​​the first connecting section (61) passes, a hollow first waterproof rubber core part in which a certain area is installed inside the first locking nut (71) and mounted on the outer periphery of the first connecting section (61), and a hollow housing (72) part in which the remaining area of ​​the first waterproof rubber core part is accommodated in the internal space and a spiral is formed on one side of the outer periphery with respect to the central part to which the first locking nut (71) is fastened.

[0108] The second connector (80) includes a second locking nut (81) through which a certain area of ​​the second connecting section (62) passes, a hollow second waterproof rubber core part in which a certain area is installed inside the second locking nut (81) and mounted on the outer circumference of the second connecting section (62), and a tube part (82) in which the remaining area of ​​the second waterproof rubber core part is accommodated in the internal space, a spiral is formed on the outer circumference to which the second locking nut (81) is fastened, and both sides are open and an empty space is formed inside.

[0109] A certain area of ​​the first connecting section (61) passes through the hollow of the first locking nut (71) and is accommodated in the internal space of the first waterproof rubber core section, while another certain area is accommodated in the internal space of the housing (72) section. The remaining area of ​​the first connecting section (61) protrudes outward and is exposed to fluid.

[0110] A certain portion of the second connecting section (62) passes through the hollow of the second locking nut (81) and is accommodated in the internal space of the second waterproof rubber core, while another certain portion is accommodated in the internal space of the tube portion (82). The remaining portion of the second connecting section (62) protrudes outward and is exposed to fluid.

[0111] Additionally, a water pipe non-disruption imaging system (1) according to one embodiment of the present invention may further include a terminal (T) for electrically connecting a first connection section (61) and a second connection section (62). The terminal (T) may be a component included in the first connector (70) or the second connector (80).

[0112] The terminal (T) is accommodated in the internal space of the housing (72) or in the internal space of the tube portion (82).

[0113] In this case, as another example, a certain area of ​​the terminal (T) may be accommodated in the internal space of the housing (72), and the remaining area may be accommodated in the internal space of the tube section (82). Also, the terminal may be fixed in the internal space of the housing (72). In this case, when the first connector (70) and the second connector (80) are separated, only a certain area of ​​the terminal is pulled out to the outside of the tube section (82).

[0114] Connection terminal grooves are formed on one side and the other side of the terminal (T), respectively.

[0115] In addition, a first connection pin is formed on one side of the first connection section (61) to be electrically connected to a connection terminal groove formed on one side of the terminal, and a second connection pin is formed on the other side of the second connection section (62) to be electrically connected to a connection terminal groove formed on the other side of the terminal.

[0116] That is, the first connecting section (61) is electrically connected to the terminal in the internal space of the housing (72), and the second connecting section (62) is electrically connected to the terminal in the internal space of the tube section (82). As a result, the first connecting section (61) and the second connecting section (62) are electrically connected through the terminal, so that power can be supplied to the imaging section (20).

[0117] And, when the first connecting section (61) connected to the terminal (T) is pulled, the first connecting section (61) is easily separated from the terminal (T), and when the second connecting section (62) connected to the terminal (T) is pulled, the second connecting section (62) is easily separated from the terminal (T). This structure can be implemented in such a way that the second connecting section (62) is easily separated from the terminal (T).

[0118] Additionally, the water pipe non-disruption imaging system (1) according to one embodiment of the present invention may further include a separation guide part (90) as shown in FIG. 4.

[0119] The separation guide section (90) operates in conjunction with the separation section (100) described later to separate the first connector (70) and the second connector (80).

[0120] And, a rotation guide groove (821) is formed along the circumferential surface of the tube portion (82) to guide the rotation of the separation guide portion (90) in place.

[0121] A rotational groove (91) is formed at one end of the separation guide portion (90). The rotational groove (91) is formed along the inner circumference of the separation guide portion (90). Both the rotational guide groove (821) and the rotational groove (91) are formed with a circular cross-sectional shape.

[0122] The rotating lip (91) wraps around the circumferential surface of the tube portion (82) and rotates in place on the rotating guide groove (821).

[0123] And, a spiral is formed on the outer circumference of the other side of the housing (72), and a spiral is formed on the inner circumference of the separation guide part (90) that is connected to the spiral of the housing (72).

[0124] Additionally, on the other side of the housing (72), a receiving portion (721) is integrally formed to be accommodated in the internal space of the tube portion (82).

[0125] At least one straight-moving bar (722) is formed on the outer circumference of the receiving portion (721), and a straight-moving bar (722) is received on the inner circumference of the tube portion (82), and a straight-moving guide groove (822) is formed to guide the straight-moving bar (722) in a straight direction.

[0126] When the straight-moving bar (722) is received in the straight-moving guide groove (822) and the spiral of the housing (72) and the spiral of the lifting guide groove are connected, the separation guide part (90) is rotated in place by the rotation drive part (103) described later, and the housing (72) moves straight in the direction of being pulled out from the internal space of the separation guide part (90), and in this process, the straight-moving bar (722) moves straight in the direction of being pulled out from the straight-moving guide groove (822).

[0127] Meanwhile, the withdrawal unit (30) is applied to the water pipe (2) and is positioned at a predetermined distance from the insertion guide unit (10), and guides the shooting unit (20) and the buoyancy unit (40) inserted into the internal space of the water pipe (2) to be withdrawn to the outside, so that a worker located on the ground can easily retrieve them.

[0128] To this end, the extraction section (30) includes at least one of the extraction pipe section (31) and the extraction member (32).

[0129] The withdrawal pipe section (31) is mounted on the water supply pipe (2) and is positioned at a certain distance from the input guide section (10).

[0130] The withdrawal pipe section (31) can be positioned at a distance of tens of meters to tens of kilometers from the input section (12). Specifically, multiple air valves, saddles, and saddle pipes can be installed in the water supply pipe (2), and these air valves, saddles, and saddle pipes are spaced apart from each other at a certain distance. For example, if the distance between air valves is 1 km, the input pipe section (11) is installed on the connecting member (3) where one air valve is installed, and the withdrawal pipe section (31) is installed on the connecting member (3) where another air valve is installed. Accordingly, the filming section (20) moves a distance of 1 km to film the inside of the water supply pipe (2) and then is withdrawn to the outside through the withdrawal section (30).

[0131] In the extraction pipe section (31), an internal space (31a) is formed that is connected to the internal space of the connecting member (3) and the internal space of the water pipe (2).

[0132] The withdrawal pipe section (31) is installed on the outer surface of the water pipe (2) in the same way as the input pipe section (11).

[0133] The withdrawal tube section (31) is installed in any one of the other fixed tubes, air valves, and saddles where the input tube section (11) is not installed.

[0134] The withdrawal pipe section (31) may also be applied to other connecting members (3) installed in the water pipe (2).

[0135] A spiral is formed on the outer circumference of the extraction pipe section (31) to be connected to a spiral formed on the inner circumference of the connecting member (3).

[0136] As another example, it is also possible to form the size of the extraction pipe (31) larger than the size of the coupling member (3) so that the extraction pipe (31) wraps around the outer circumference of the coupling member (3).

[0137] In such a case, a spiral may be formed on the inner circumference of the extraction pipe section (31), and a spiral to which the spiral of the extraction pipe section (31) is fastened may be formed on the outer circumference of the coupling member (3), thereby connecting the extraction pipe section (31) to the coupling member (3) in a spiral fastening manner.

[0138] If you want to apply the extraction tube (31) to the saddle, you can drill a hole in the saddle and then insert the extraction tube (31) into the hole.

[0139] And, after the camera unit (20) is retrieved to the ground, the hole can be closed by bolting a separate plug to the bird.

[0140] Meanwhile, the extraction member (32) includes an additional receiving tube section (321) and a second direction change section (322).

[0141] The additional receiving tube section (321) is accommodated in the internal space (31a) of the withdrawal tube section (31).

[0142] At this time, a spiral (not shown) that is connected to each other is formed along the length direction on the inner circumference of the extraction pipe section (31) and the outer circumference of the receiving pipe section (321).

[0143] As a result, the additional receiving tube (321) can be easily connected to the withdrawal tube (31) in a spiral manner.

[0144] An extraction passage is formed inside the additional receiving pipe section (321) to extract the imaging section (20) and the buoyancy section (40). The imaging section (20) and the buoyancy section (40), located in the internal space of the water pipe (2), are extracted to the outside of the water pipe (2) through the extraction passage of the additional receiving pipe section (121).

[0145] The second direction changing section (322) is formed on one side of the additional receiving section (321) and is received in the internal space of the sewer pipe (2). The second direction changing section (322) is curved in shape to smoothly change the direction of movement of the shooting section (20) and the buoyancy section (40), which have moved along the internal space of the water pipe (2), to the direction of the withdrawal passage.

[0146] As described above, the input guide section (10) is positioned at a distance of tens of meters to tens of kilometers from the output section (30), so the output member (32) and the input section (12) face each other at a distance of tens of meters to tens of kilometers.

[0147] And, the second direction change unit (322) is placed on the flow path of the shooting unit (20) when it is inserted into the internal space of the water pipe (2).

[0148] The shooting unit (20) and the buoyancy unit (40) proceed along the fluid in the water pipe (2), and when they reach the withdrawal member (32), they sequentially rise along the withdrawal passage of the second direction change unit (322) and the additional receiving pipe unit (321), and the operator retrieves the buoyancy unit (40) and the shooting unit (20) that have risen to the top of the withdrawal passage.

[0149] At this time, the worker located on the ground can check the image captured by the shooting unit (20) inside the water pipe (2), so when the second direction change unit (322) is visible in the image captured by the shooting unit (20), the timing for withdrawing the buoyancy unit (40) and the shooting unit (20) can be anticipated.

[0150] As an example for withdrawing the buoyancy unit (40) and the shooting unit (20), when the buoyancy unit (40) reaches the side of the second direction change unit (322), the operator operates the rotation drive unit (103) of the aforementioned separation unit (100) to separate the first connector (70) and the second connector (80). In this case, the resistance (pulling force) of the connecting cable (60) acting on the buoyancy unit (40) is released. Therefore, when the propeller (50) is rotated by driving the motor (51), a thrust force is generated in the buoyancy unit (40). As a result, the buoyancy unit (40) rises along the second direction change unit (322) and is positioned in the withdrawal passage of the additional receiving pipe unit (321). This allows the operator to easily retrieve the shooting unit (20) and the buoyancy unit (40) that have risen to the withdrawal passage. Then, the second connecting section (62) is wound through a winding machine and the second connecting section (62) is retrieved from the input pipe section (11).

[0151] Then, by connecting the first connector (70) and the second connector (80) on the ground to electrically connect the first connection section (61) and the second connection section (62), power is supplied again to the shooting unit (20), and then the shooting unit (20) is inserted into the water pipe (2) to be photographed next.

[0152] As another example for withdrawing the buoyancy unit (40) and the shooting unit (20), the connecting cable (60) is unwound by a winding machine, and is unwound sufficiently so that no pulling force of the connecting cable (60) is generated in the shooting unit (20) while propulsion force is generated in the buoyancy unit (40) by the rotation of the propeller (50). At the same time, the motor (51) is operated to rotate the propeller (50), causing the buoyancy unit (40) to rise along the second direction change unit (322) and be positioned in the withdrawal passage of the additional receiving pipe unit (321). Accordingly, the operator retrieves the buoyancy unit (40) that has risen to the withdrawal passage, and then operates the rotation drive unit (103) of the separation unit (100) to separate the first connector (70) and the second connector (80). Then, the second connecting section (62) is wound through a winding machine and the second connecting section (62) is retrieved from the input pipe section (11).

[0153] And, as described above, by connecting the first connector (70) and the second connector (80) on the ground to electrically connect the first connection section (61) and the second connection section (62), power is supplied again to the shooting unit (20), and then the shooting unit (20) is inserted into the water pipe (2) to be photographed next.

[0154] Meanwhile, the separation unit (100) is configured to separate the first connector (70) and the second connector (80) before withdrawing the shooting unit (20) from the water pipe (2).

[0155] At this time, in a water pipe non-extraction imaging system according to one embodiment of the present invention, the separation unit (100) may not be applied as shown in FIG. 1 and FIG. 3, or may be applied as shown in FIG. 4.

[0156] Referring to FIG. 4, the separation unit (100) may include at least one of a first gear unit (101), a second gear unit (102), and a rotary drive unit (103).

[0157] The first gear part (101) can be applied to the first connector (70) or the second connector (80).

[0158] In the drawing, an example is shown in which the separation guide part (90) is applied to the second connector (80) and the first gear part (101) is mounted on the outer circumference of the separation guide part (90), so the first gear part (101) is applied to the second connector (80) side.

[0159] The second gear unit (102) meshes with the first gear unit (101). The second gear unit (102) transmits power from the rotary drive unit (103) to the first gear unit (101).

[0160] The rotary drive unit (103) is formed by a motor. Since the rotary drive unit (103) comes into contact with the fluid flowing through the internal space of the water pipe (2), it is waterproofed in the same way as the motor (51) described above.

[0161] A connecting plate (621) is formed on one side of the tube portion (82).

[0162] The rotary drive unit (103) is connected to the connecting plate (621) via a bolt or nut.

[0163] The rotary drive unit (103) rotates the second gear unit (102) so that the first connector (70) and the second connector (80) are separated.

[0164] The aforementioned operating device is provided with a 2-1 button for rotating the drive shaft of the rotary drive unit (103) in the forward direction and a 2-2 button for rotating the drive shaft in the reverse direction.

[0165] As described above, the first connector (70) and the second connector (80) must be separated before the buoyancy part (40) is pulled out of the water pipe (2) through the withdrawal part (30).

[0166] Accordingly, the buoyancy unit (40) is positioned on the additional inclined surface (321) or the rising guide surface (322), and then the drive shaft of the rotary drive unit (103) is rotated by pressing the 2-1 button or the 2-2 button. At this time, the position of the additional inclined surface (321) or the rising guide surface (322) can be checked through the camera unit (20), and the propeller (50) can be rotated through the motor (51) to position the buoyancy unit (40) on the additional inclined surface (321) or the rising guide surface (322). Then, after positioning the buoyancy unit (40) on the additional inclined surface (321) or the rising guide surface (322), the motor (51) can be stopped or maintained in an operating state.

[0167] As the drive shaft of the rotary drive unit (103) rotates, the separation guide unit (90) also rotates.

[0168] At this time, the drive shaft rotates in the direction in which the housing (72) is separated from the separation guide part (90). That is, the drive shaft rotates in the direction in which the spiral of the housing (72) and the spiral of the separation guide part (90), which were connected to each other, are released.

[0169] And, when the separation guide part (90) is rotated in the direction of pulling out the housing (72), the spiral of the housing (72) is released from the spiral of the separation guide part (90), and the straight-moving bar (722) is pulled out from the straight-moving guide groove (822).

[0170] As a result, the housing (72) is sequentially withdrawn from the tube section (82) and the separation guide section (90). Eventually, the first connection section (61) is separated from the terminal (T), and the first connector (70) is separated from the second connector (80), so that only the first connector (70), the first connection section (61), the buoyancy section (40), and the imaging section (20) can be withdrawn outside the water pipe (2).

[0171] At this time, after separating the first connector (70) from the second connector (80), the motor (51) of the propeller (50) is operated to raise the first connector (70), the first connecting section (61), the buoyancy section (40), and the shooting section (20) to the extraction passage of the additional receiving section (321) through propulsion force, and then the operator can manually extract the first connector (70), the first connecting section (61), the buoyancy section (40), and the shooting section (20) located on the extraction passage.

[0172] As another example, the motor (51) of the propeller (50) may be operated to generate thrust, thereby pulling the first connector (70), the first connecting section (61), the buoyancy section (40), and the shooting section (20) out to the upper outside of the extraction tube section (31).

[0173] In this way, after the first connector (70), the first connecting section (61), the buoyancy section (40), and the imaging section (20) are pulled out of the water pipe (2), the second connecting section (62) is wound through a winding machine. At this time, the second connecting section (62) and the second connector (80) mounted on the second connecting section (62) are pulled out of the water pipe (2) through the input passage (11a) of the input pipe section (11).

[0174] Meanwhile, the first connector (70), the first connecting section (61), the buoyancy section (40), and the shooting section (20) are brought out to the outside of the water pipe (2), and the second connecting section (62) and the second connector (80) are also brought out to the outside of the water pipe (2). After connecting the first connector (70) and the second connector (80), the location is moved to photograph another part of the water pipe (2).

[0175] As described above, the water pipe non-stop shooting system (1) according to one embodiment of the present invention can easily insert and withdraw the shooting unit (20) and the buoyancy unit (40) into and out of the internal space of the water pipe (2) through any one selected from a saddle, an air valve, and a saddle, and by making the buoyancy unit (40) into a submersible shape or a streamlined shape and moving it smoothly while floating due to the fluid present in the internal space of the water pipe (2), the inside of the water pipe (2) can be accurately shot with the shooting unit (20).

[0176] In addition, the water pipe non-disruption shooting system (1) according to one embodiment of the present invention includes technical features such as being able to automatically separate the first connector (70) and the second connector (80) within the internal space of the water pipe (2), connecting the shooting unit (20) to the first connector (70), and setting the withdrawal unit (30) on the fluid flow direction, which is the shooting direction (A). That is, the connecting cable (60) is retrieved from the insertion guide (10), which is the insertion point of the shooting unit (20), and the shooting unit (20) is withdrawn at a desired location, so that the shooting unit (20) does not receive resistance from the fluid flow.

[0177] As a result, the camera unit (20) can be moved within the interior space of the water pipe (2) for tens of meters to tens of kilometers to take pictures.

[0178] A person skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included within the scope of the present invention.
