Description

Technical Field

[0001] This invention relates to an underground power distribution line monitoring device for monitoring the internal condition of underground power distribution lines laid inside underground pipelines. Background Technology

[0002] While power distribution lines are typically laid throughout the state during construction, they have recently been buried underground to beautify the environment and prevent electric shock accidents.

[0003] Underground power distribution lines are laid by burying underground pipes. Because of the underground pipes or power distribution lines, there are problems such as corrosion of the underground pipes or power distribution lines, and water leakage in the underground pipes causing the power distribution lines to be flooded and short-circuit accidents.

[0004] To address this issue, a patent application for "Integrated Monitoring Device for Distribution Lines and Pipelines of Pipeline-Type Underground Power Distribution Lines" was previously initiated in Korean Patent Registration No. 10-23122768 (published on October 13, 2021).

[0005] The aforementioned integrated monitoring device for power distribution lines and pipelines refers to an underground power distribution line located inside a hollow underground pipeline. The power distribution line moves along the first direction of the pipeline's length. It has a through section through which the power distribution line passes, with the cross-sectional shape of the through section matching that of the power distribution line, thus forming a body that contacts the power distribution line. A moving module is installed on the outer surface of the main unit, contacting and driving the inner surface of the pipeline. It includes a first driving wheel and the inner surface of the through section, as well as a second driving wheel that contacts and drives the power distribution line. The device is installed inside the through section and consists of multiple needle probes that reciprocate in a second direction at the center of the through section, and a current sensing module that senses the current value through the needle probes. Multiple points are formed at intervals along the first direction of the power distribution line. The needle points are located directly below the synthetic resin outer shell of the power distribution line conductor. When the needle probes are in position, they move outward in the second direction to sense the current, which is then sensed by the module. A current abnormality sensor to determine whether there is an abnormal current; and a camera placed on both sides of the host in the first direction, forming a shooting area including the inner surface of the pipe and the power distribution line from at least one side of the host, to shoot the shooting area in front of one side of the host.

[0006] This traditional integrated monitoring device for power distribution lines and pipelines can detect whether there are any abnormalities in the power distribution lines by using probes when the main unit is traveling through underground pipelines.

[0007] However, the problem with traditional integrated monitoring devices for power distribution lines and pipelines is that, since the first and second drive wheels are driven by motors, the main unit is relatively large, making it difficult to enter the underground pipeline if it is deformed.

[0008] In addition, since the main unit drags the external power cord connected to the main unit into the underground pipe to power the motors that drive the first and second drive wheels, it is relatively heavy. If multiple power distribution lines are installed, there is a problem that they cannot enter the underground pipe.

[0009] In addition, there were previous problems such as the inability to measure the deformation of underground pipelines caused by soil pressure, the difficulty in measuring the temperature of power distribution lines, the inability to respond to fires, and the difficulty in determining the location of the main unit in underground pipelines. Summary of the Invention

[0010] The problem that the invention aims to solve

[0011] The present invention aims to solve the aforementioned problems. The subject matter to be addressed by the present invention is to configure a sensor bracket for monitoring the status of power distribution lines to be driven by the fluid pressure in the pressure supply pipe installed on the underground pipeline, thereby eliminating the need to install a motor to drive the sensor bracket, making it compact in size, and allowing easy access to the relatively small space of the underground pipeline for monitoring power distribution lines. Furthermore, the sensor bracket is configured with a battery, enabling the sensor to be powered by connecting to a power line, thus providing power to the relatively small space of the sensor bracket.

[0012] In addition, the purpose of this invention is to form a pipe support frame on the pressure supply pipe, and to install the pressure supply pipe on the underground pipeline in the form of a pipe support frame, thereby providing an underground power distribution line monitoring device that can conveniently install the pressure supply pipe on the underground pipeline.

[0013] In addition, the purpose of this invention is to provide a monitoring device for underground power distribution lines, which uses the magnetic force of the magnetic attachment part to attach the moving body of the pipe that moves the fluid pressure in the pressure supply pipe and the sensor carrier located outside the pressure supply pipe to each other, thereby facilitating the connection between the sensor carrier and the moving body.

[0014] Furthermore, the purpose of this invention is to install an observation sensor on a sensor carrier, which, while measuring the deformation of underground pipelines, simultaneously captures images of the heating of power distribution lines using an infrared camera to respond to fires, and captures images using a video camera, thus providing an underground power distribution line monitoring device that can understand the internal state of underground pipelines.

[0015] Furthermore, the purpose of this invention is to display a position mark on the pressure supply pipe and install a position sensor on the sensor bracket to detect the position mark, thereby providing a monitoring device for underground power distribution lines and facilitating the understanding of the position of the sensor bracket on the underground pipeline and the location of any problems.

[0016] means for solving problems

[0017] To accomplish the aforementioned task, according to an embodiment of the present invention, a monitoring device for underground power distribution lines is located on the upper inner side of an underground pipeline. A pressure pipe, which provides fluid pressure and is inserted from one side to the other, is inserted into the pressure supply pipe and moved by the fluid pressure. A pipe is located outside the pressure supply pipe and travels along it. The sensor is moved according to the state of the power distribution lines arranged inside the pressure supply pipe, based on the sensor and the pressure supply carrier. A magnetic attachment part, through which the pipe moving body and the sensor carrier are magnetically attached, provides fluid pressure to the pressure supply pipe. A pressure instrument provides fluid pressure to the pressure supply pipe. Information detected by the plurality of sensors mounted on the sensor bracket, including monitoring terminals monitoring the power distribution lines, is used. The sensor bracket is moved from the pressure supply pipe to the fluid pressure pipe by the machine body, thereby eliminating the need for a motor and power cord connection to drive the sensor bracket, making the sensor bracket compact and lightweight.

[0018] The support tube is a pleated tube, and the pressure supply tube extends downward on both sides of the pressure supply tube and is supported on the bone of the pleated tube. It may include a plurality of spaced tube support rods formed along the length of the pressure supply tube.

[0019] The plurality of sensors may include a camera that captures images of the power distribution line to detect the state of the power distribution line, and a pipe measuring sensor on the sensor carrier that measures the spacing between the underground pipes to detect the shape deformation of the underground pipes.

[0020] The pressure supply tube includes position markers displayed at regular intervals on the pressure supply tube, and the plurality of sensing sensors may include position sensing sensors on the sensor carrier that detect the position markers in order to determine the position of the sensor carrier in the pressure supply tube.

[0021] Invention Effects

[0022] According to the present invention, a pressure supply pipe acting on fluid pressure is installed on an underground pipeline, and a fluid pressure driven pipe moving body is installed on the pressure supply pipe, so that the fluid pressure driven pipe moving body drives the sensor carrier. The sensor carrier does not need to be equipped with a drive motor, which can make the size of the sensor carrier compact. Therefore, the sensor carrier can also operate on relatively narrow underground pipelines, which is convenient for power distribution monitoring.

[0023] Furthermore, this invention enables the sensor bracket to be driven by the fluid pressure of the moving tube, eliminating the need for a power source for the drive motor and allowing for the installation of a battery with minimal size, thereby minimizing the size and weight of the sensor bracket.

[0024] In addition, the present invention can also provide a pipe support frame on the pressure supply pipe, so that the pipe support frame spans the backbone of the underground pipeline, making it convenient to install the pressure supply pipe on the underground pipeline.

[0025] Furthermore, the present invention connects the tube moving body located inside the pressure supply tube to the sensor carrier located outside the pressure supply tube through a magnetic attachment part, thus making it convenient to connect the tube moving body and the sensor carrier.

[0026] Furthermore, this invention installs observation sensors on a sensor carrier, which can easily understand the deformation state of underground pipelines. By installing an infrared camera to measure the heat of power distribution lines, the occurrence of fires can be predicted in advance and responses can be taken.

[0027] In addition, the present invention installs a position sensor on the sensor carrier and forms a position marker on the pressure supply pipe. By detecting the form of the position marker by the position sensor, it is not only convenient to know the position of the sensor carrier on the underground pipeline, but also convenient to find out the location of the problem and take measures.

[0046] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0047] like Figure 1 As shown, according to an embodiment of the present invention, the monitoring device 100 for underground power distribution lines can monitor the status of the power distribution lines 200 laid on the underground pipe 110.

[0048] The underground pipe 110 can be a corrugated or spiral-shaped corrugated pipe with bone and acid.

[0049] like Figures 1 to 4 As shown, according to an embodiment of the present invention, the monitoring device 100 for underground power distribution lines monitors the pressure of the power distribution line 200 by means of a sensor bracket 140 for installing multiple sensing sensors, a pressure supply pipe 120 for providing fluid pressure to monitor the state of the power distribution line 200, a pipe 130 for moving the pipe with multiple sensing sensors, a pressure supply pipe 160 for providing fluid pressure to monitor the power distribution line 200, and a monitoring device 170 with multiple sensing sensors 170.

[0050] like Figures 2 to 4 As shown, the pressure supply pipe 120 is in the form of a hollow pipe, which can be laid inside the underground pipe 110 along the length of the underground pipe 110 and together with the power distribution line 200. The pressure supply pipe 120 can be flexibly bent together with the underground pipe 110 to form a material.

[0051] The pressure supply tube 120 is shown in the figure as having a quadrangular cross section, but it may also have a circular cross section or a polygonal cross section other than the quadrangular cross section. However, the pressure supply tube 120 preferably has a quadrangular or polygonal cross section to prevent the tube body 130 moving along the inside of the pressure supply tube 120 from rotating inside the pressure supply tube 120.

[0052] The pressure supply line 120 can be supplied with fluid pressure by the pressure instrument 160, and the fluid pressure of the pressure supply line 120 can provide fluid pressure flowing from one end of the pressure supply line 120 to the other end of the pressure supply line 120.

[0053] The fluid pressure can be either air pressure or oil pressure. Depending on whether it is air or oil pressure, the pressure machine 160 can be powered by a hydraulic pump or an air compressor.

[0054] The pressure machine 160 is connected to the fluid outlet 161 of the pressure machine 160 to provide fluid pressure to the pressure supply pipe 120. The tower end of the pressure supply pipe 120 is connected to the fluid inlet 163 of the pressure machine 160, so that the fluid discharged from the fluid outlet 161 enters one end of the pressure supply pipe 120, and the fluid discharged from the tower end of the pressure supply pipe 120 can circulate through the fluid inlet 163.

[0055] The pressure supply pipe 120 can be located in the direction facing the power distribution line 200 laid at the lower end of the inner column of the underground pipe 110—the upper end of the inner column of the underground pipe 110. The pressure supply pipe 120 may include a pipe support frame 123.

[0056] like Figure 2 and Figure 3 As shown, the pipe support frame 123 is a configuration for supporting and fixing the pressure supply pipe 120 on the underground pipeline 110. The pipe support frame 123 can extend downward from the upper part of the pressure supply pipe 120 to both sides.

[0057] At this time, the pipe support frame 123 can form a raised arc shape from both sides of the pressure supply pipe 120 to correspond to the inner column of the underground pipe 110.

[0058] The tube support frame 123 can be elastically attached together to form a shape that is more open than the outer sides of the lower ends of the inner diameter of the pressure supply tube 120, so as to support the inner circumference of the pressure supply tube 120.

[0059] The pipe support frame 123 can be placed at multiple intervals along the length of the pressure supply pipe 120. The pipe support frame 123 is inserted into the inner column portion 111 of the underground pipe 110, which can prevent the pressure supply pipe 120 from moving from the underground pipe 110 to the length of the pressure supply pipe 120.

[0060] The pipe support frame 123 is inserted into the underground pipe 110 with its two ends folded together. When inserted into the underground pipe 110, the two ends of the pipe support frame 123 unfold by elastic force and insert into the corresponding bone parts 111, so that a pressure supply pipe 120 can be installed on the underground pipe 110.

[0061] When the pipe support frame 123 is folded at both ends, a pressure supply pipe 120 is inserted into an installation pipe with a diameter smaller than that of the underground pipe 110. The installation pipe is removed while the underground pipe 110 is inserted. As the pipe support frame 123 unfolds, the pressure supply pipe 120 can be installed on the underground pipe 110 in the form of being inserted into the bone 111 of the underground pipe 110.

[0062] like Figure 3 and Figure 4 As shown, the tube moving body 130 can be inserted into the interior of the pressure supply tube 120 and moves along the pressure supply tube 120 by the fluid pressure acting on the pressure supply tube 120.

[0063] The moving body 130 is inserted into the interior of the pressure supply pipe 120 and installed in the form of a sealed pressure supply pipe 120. It can move from one end of the pressure supply pipe 120 to the impact end along the pressure supply pipe 120 according to the output force of the fluid provided at one end of the pressure supply pipe 120 and the suction force of the fluid provided at the impact end of the pressure supply pipe 120.

[0064] The moving body 130 may have an outer periphery corresponding to the inner periphery of the pressure supply pipe 120. The moving body 130 may move from one end of the pressure supply pipe 120 to the end of the tower, depending on the direction of the fluid pressure acting on the pressure supply pipe 120.

[0065] For example, if the pressure machine 160 is operating in the forward direction, discharging fluid from the fluid outlet 161 and drawing fluid from the fluid inlet 163, the pipeline may move from one end of the pressure supply pipe 120 connected to the fluid outlet 161 to the other end of the pressure supply pipe 120 connected to the fluid inlet 163.

[0066] Conversely, if the pressure machine 160 operates in reverse, drawing in fluid from the fluid outlet 161 and discharging fluid from the fluid inlet 163, then at the end of the pressure supply pipe 120 connected to the fluid inlet 163 and at one end of the pressure supply pipe 120 connected to the fluid outlet 161, the pipe can be moved to the fluid outlet 130.

[0067] In the embodiment, the forward or reverse movement of the pressure machine 160 indicates that the direction of movement of the tube mover 130 on the pressure supply tube 120 has changed. However, the fluid discharged to the fluid outlet 161 will be supplied as the end of the pressure supply tube 120 through a separate path, and the fluid discharged to the fluid inlet 163 can also be discharged from one end of the pressure supply tube 120.

[0068] The moving body 130 moves into the interior of the pressure supply pipe 120, which can provide power for the sensor carrier 140 to move along the pressure supply pipe 120.

[0069] The pipe moving body 130 located inside the pressure supply pipe 120 and the sensor carrier 140 located outside the pressure supply pipe 120 are magnetically attached to each other. When the pipe moving body 130 moves, the sensor carrier 140 can move along the pressure supply pipe 120 together with the pipe moving body 130.

[0070] The tube moving body 130 and the sensor carrier 140 can be composed of a magnetic attachment part 150. A permanent magnet 151 can be installed on either the tube moving body 130 or the sensor carrier 140, and a pizza body 153 made of magnetically attached iron metal can be installed on the other. The two parts can be magnetically attached to each other or the tube moving body 130 and the sensor carrier 151 can be respectively attached to each other by permanent magnets.

[0071] At this time, when the sensor bracket 140 moves on the pressure supply tube 120, in order to minimize friction, it maintains a small gap with the outer surface of the pressure supply tube 120, and the tube can be attached to each other by the body 130 and magnetism.

[0072] like Figure 3 and Figure 4 As shown, the sensor bracket 140 is installed on the outside of the pressure supply pipe 120 and can monitor the power distribution line 200 installed on the underground pipe 110. It also moves with the pipe body 130.

[0073] The sensor bracket 140 can be equipped with multiple sensors to monitor the status of the power distribution line 200.

[0074] The sensor bracket 140 can be streamlined so that it can be easily moved even if the underground pipe 110 is filled with water due to leakage. The sensor bracket 140 can be fitted with a bracket label 140a to prevent it from falling off the pressure supply pipe 120.

[0075] At this time, a guide groove 121 spanning the carrier label 140a is formed on the pressure supply tube 120 along the length of the pressure supply tube 120 on both sides of the pressure supply tube 120. The carrier label 140a spans the guide groove 121, which can prevent the sensor 140 from separating from the pressure supply tube 120 even if the tube does not provide magnetic force to the body 130.

[0076] The bracket 140a extends from the upper part of the sensor bracket 140 to the upper parts of both sides. The brackets 140a on both sides can be inserted into the guide grooves 121 on both sides of the pressure supply pipe 120. The brackets 140a can be equipped with rollers 140 to minimize the friction with the guide grooves 121 when the sensor bracket 140 moves, so as to travel along the guide grooves 121.

[0077] Multiple sensors installed inside the sensor bracket 140 may include a camera 141, an observation sensor 143, and a position sensor 145.

[0078] The lower part of the sensor bracket 140 is transparent, allowing viewing through the power distribution line 200 located below. A camera 141 can be mounted on the sensor bracket 140 to capture images of the power distribution line 200 located below.

[0079] Camera 141 may include video camera 141a and infrared cameras 141b and 141.

[0080] The video camera 141a captures the original appearance of the power distribution line 200 when viewed from the outside. The video camera 141a can capture video of the power distribution line and monitor the condition of the outer shell of the power distribution line 200 after corrosion through the captured video.

[0081] Infrared cameras 141b and 141 capture images of the heat generated by the power distribution line 200. By capturing infrared images of the power distribution line 200, infrared cameras 141b and 141 can measure the heat generated by the power distribution line 200 and prevent fires.

[0082] The observation sensor 143 measures the distance from the sensor carrier 140 to the preset interior of the underground pipe 110, and can monitor the deformation or bending of the underground pipe 110 under external forces.

[0083] The observation sensor 143 measures the distance from the moving sensor carrier 140 to a preset position of the underground pipeline 110, and can predict damage such as deformation of the underground pipeline 110 caused by external pressure.

[0084] For example, if the underground tube 110 is circular, it will deform like an ellipse under the action of external force, and the radius will change. Therefore, the underground tube 110 will not deform. If it remains circular, the distance from the sensor bracket 140 to a specific position of the underground tube 110 will not change. However, if the underground tube 110 deforms, the deformation of the underground tube 143 can be predicted by the change in the distance from the sensor bracket 140 to a specific position of the underground tube 110.

[0085] The observation sensor 143 can be implemented by a distance measurement sensor that measures distance using laser.

[0086] The position sensor 145 is installed inside the sensor bracket 140 and can measure the movement position of the sensor bracket 140.

[0087] The position sensor 145 can detect the movement of the sensor bracket 140 in the form of a position measuring device displayed on the pressure supply pipe 120.

[0088] Here, a position measuring device formed on the pressure supply pipe 120 forms a scale in the form of a strip at a preset interval of the pressure supply pipe 120. The position sensor 145 can detect the scale and measure the position of the sensor bracket 140 by counting the detected scale.

[0089] For example, if the pressure supply pipe 120 forms a scale every 100 millimeters, and the position sensor 145 detects 10 scales starting from the inlet of the underground pipe 110, then the position of the sensor carrier 140 at a position of 1 meter starting from the inlet of the underground pipe 110 can be predicted.

[0090] The position sensor 145 can be implemented by a laser sensor that detects scale like a barcode by transmitting and receiving lasers.

[0091] Of course, the position sensor 145 transmits and receives laser light from the sensor carrier 140 to the pressure supply tube 120.

[0092] The sensor bracket 140 may also include lighting, a wireless communication module 147, and a battery 149.

[0093] The lighting can illuminate the dark interior of the underground pipe 110, which helps the camera 141 to capture video.

[0094] The lighting can be achieved using LED lighting, and the light can be directed in the direction captured by camera 141.

[0095] The wireless communication module 147 can transmit the status information of the power distribution line 200 detected by the sensor carrier 140 to the monitoring terminal 170 via wireless communication.

[0096] The wireless communication module 147 can send the information measured by the monitoring terminal 170 through short-range communication such as WI-FI, Zigbee, and Bluetooth, or remote communication such as 3G, 4G, and 5G mobile communication.

[0097] Battery 149 can provide illumination mounted on sensor bracket 140, as well as power for operating multiple sensors.

[0098] The sensor bracket 140 is not motor-driven; multiple sensors are optically driven, which minimizes the capacity of the battery 149 and reduces the weight of the sensor bracket 140.

[0099] The monitoring terminal 170 can display the information detected on the sensor bracket 140 on the monitor, thereby monitoring the status of the wiring.

[0100] The monitoring terminal 170 can receive video captured by video camera 141a and infrared images captured by infrared cameras 141b and 141 in real time from the sensor carrier 140 and display them on the monitor. The status of the underground pipeline 110 and the distance moved by the position sensing sensor 145 can be displayed simultaneously by the information measured by the observation sensor 143.

[0101] The following explains the roles and effects of each component.

[0102] According to an embodiment of the present invention, the monitoring device 100 for underground power distribution lines has a pressure supply pipe 120 inside the underground pipe 110, and the two sides of the pressure supply pipe 120 correspond to the inner columns of the underground pipe 110 to form a pipe support frame 123.

[0103] The pipe support frame 123 is formed by multiple support frames separated along the length of the pressure supply pipe 120. The pipe support frame 123 is close to the inner column of the underground pipe 110 and supports the pressure supply pipe 120 located on the upper inner side of the underground pipe 110.

[0104] The pressure supply pipe 120 can be connected to a pressure machine 160 that provides fluid pressure. The pressure machine 160 connects its fluid outlet 161 to one end of the pressure supply pipe 120 and its fluid inlet 163 to the end of the pressure supply pipe 120.

[0105] Inside the pressure supply pipe 120, a pipe moving body 130 is inserted, which moves along the pressure supply pipe 120 according to the fluid pressure provided by the pressure supply pipe 120. The pipe moving body 130 may move to one side of the pressure supply pipe 120, move in other directions, or stop moving according to the fluid pressure applied by the pressure machine 160.

[0106] At the lower part of the pressure supply pipe 120, the sensor carrier 140 is magnetically attached to the body 130 by the magnetic attachment part 150, allowing the pipe to move together with the body 130. The sensor carrier 140 will have a carrier label 140a installed on the guide groove 121 formed on the side of the pressure supply pipe 120, which will reduce the friction between the carrier label 140 and the guide groove 140.

[0107] The sensor bracket 140 is equipped with multiple sensors for detecting the power distribution line 200 laid inside the underground pipe 110. The sensors include a video camera 141a for capturing images of the power distribution line 200, an infrared camera 141b and 141 for measuring the temperature of the power distribution line 200, lighting for illuminating the interior of the underground pipe 110, a sensor 145 for measuring the deformation of the underground pipe 110, and the position of the sensor 140.

[0108] In addition, the sensor bracket 140 will mount a wireless communication module 147 and multiple sensing sensors, as well as a battery 149 that provides power for the lighting, for wireless communication to provide information measured by the monitoring terminal 170.

[0109] According to the embodiment of the present invention with the above-described configuration, the monitoring device 100 for underground power distribution lines activates the pressure gauge 160 to monitor the power distribution line 200.

[0110] After the pressure machine 160 is started, the fluid from the pressure machine 160 is discharged through the fluid outlet 161 and supplied as part of the pressure supply pipe 120. At the tower end of the pressure supply pipe 120, the fluid supplied by the pressure machine 160 is drawn in through the fluid inlet 163, generating fluid pressure, and the fluid moves from one end of the pressure supply pipe 120 to the tower end.

[0111] When the pressure supply pipe 120 generates fluid pressure, the pipe moving body 130 inserted inside the pressure supply pipe 120 moves from one end of the pressure supply pipe 120 to the hitting end.

[0112] At this time, the moving speed of the pipe moving body 130 can be controlled by the fluid pressure provided by the pressure machine 160.

[0113] When the tube moving body 130 moves on the pressure supply tube 120, the sensor carrier 140, which is magnetically attached by the tube moving body 130 and the magnetic attachment part 150, moves along the carrier 130 on the outside of the pressure supply tube 120, and the sensor carrier 140 moves along the pressure supply tube 120.

[0114] When the sensor bracket 140 moves, the interior of the underground pipe (110) will be illuminated as the lighting is turned on. The video camera 141a and infrared cameras 141b and 141 installed on the sensor bracket 140 will capture visible light video and infrared video respectively, and transmit the captured video to the monitoring terminal 170 through the wireless communication module 147.

[0115] At the same time, the sensor carrier 140 measures the distance from the sensor carrier 140 to a specific location (a point in the radial direction) of the underground pipeline 110 by the observation sensor 143, and the position sensor 145 measures the distance by detecting the position mark 125 formed on the pressure supply pipe 120.

[0116] Of course, the tube information measured by the tube measurement sensor 143 and the position information measured by the position sensor 145 are also provided as a display terminal via the wireless communication module 147.

[0117] On the monitoring terminal 170, the visible light images captured by the video camera 141a can reveal the internal condition of the power distribution line 200, such as damage to the underground pipe 110, water inflow, or the condition of the outer casing of the power distribution line 200. Infrared images can reveal the heat generated by the power distribution line 200.

[0118] Furthermore, the deformation of the underground pipeline 110 can be understood through the information provided by the observation sensor 143, thereby understanding the damage to the underground pipeline 110 caused by earth pressure.

[0119] At this time, the monitoring terminal 170 can detect the position mark 125 formed on the position tube 120 by detecting the pressure detected by the position sensor 145, and provide the position information of the sensor bracket 140, so as to conveniently grasp the location of the problem and take measures in advance.

[0120] On the other hand, if the sensor bracket 140 moves from one end of the pressure supply pipe 120 to the hitting end to complete the monitoring of the wiring line, the sensor bracket 140 can be removed from the pressure supply pipe 120 to end the monitoring by removing the pressure instrument 160 from the pressure supply pipe 120. Alternatively, without removing the sensor bracket 140, the moving pipe 130 can be repeatedly monitored from the hitting end of the pressure supply pipe 120 to one end in reverse order by using the pressure instrument 160, and the wiring 200 can continue in reverse order.

[0121] Therefore, according to an embodiment of the present invention, the monitoring device 100 for underground power distribution lines configures the sensor bracket 140 to move along the pressure supply pipe 120 installed on the underground pipe 110, which is driven by the body 130. There is no need to install a motor on the sensor bracket 140, so the volume of the sensor bracket 140 can be minimized. This allows for convenient monitoring of the power distribution line 200 even on the relatively narrow underground pipe 110, while also allowing the sensor 140 to be driven with a relatively light weight.

[0122] In addition, the present invention drives the sensor carrier 140 by the fluid pressure acting on the pressure supply pipe 120, which does not require complex equipment, thus reducing equipment costs and making it easy to maintain.

[0123] In addition, the present invention forms a pipe support frame 123 on the pressure supply pipe 120 and installs it in the form of supporting the pipe support frame 123 on the corrugated or spiral pipe bone portion 111, so that the pressure supply pipe 120 can be conveniently installed on the underground pipe 110.

[0124] In addition, the present invention has installed an observation sensor 143 on the sensor carrier 140, which can not only conveniently monitor the deformation of the underground pipeline 110, but also conveniently understand the status of the underground pipeline 110 or the power distribution line 200 through the video camera 141a. The infrared cameras 141b and 141 can predict fires caused by temperature changes in the power distribution line 200 and take preventive control measures.

[0125] In addition, the present invention also includes a position indicator 125 that displays the position on the pressure supply pipe 120, and a position sensor 145 that detects the position indicator 125 is installed on the sensor bracket 140, which can conveniently determine the position of the sensor bracket 140 on the underground pipeline 110.

[0126] The embodiments of the present invention have been described above, but the scope of the present invention is not limited thereto, and includes all changes and modifications in the technical field to which the present invention pertains that are easily altered by a person with ordinary knowledge and are considered to be of equal scope.
