Description

The Device for Monitoring Buried Pipe}

The present invention relates to a buried pipe monitoring device, and more particularly, it is possible to collect data from a measuring device installed inside the buried pipe, and install by connecting the buried pipe and the ground so that the internal situation of the buried pipe can be observed in real time through a camera It relates to a buried pipe monitoring device.

The buried pipe includes a sewage pipe for collecting sewage and rainwater and transporting it to a sewage treatment plant and discharge area, and a sewage pipe network is formed underground by determining a drainage area and a treatment area. In addition, the buried pipe includes a waste water discharge pipe buried to discharge waste water produced by a waste water producer.

If continuous maintenance and management of these buried pipes are not carried out, the function of the sewage treatment facility is deteriorated due to deterioration, and when cracks occur, the soil and cement paste of the ground layer covering the buried pipe are transferred to the inside of the buried pipe. Can be introduced.

In addition, the transport function is weakened by the soil and organic sediments flowing into the buried pipe, and rainwater may overflow, contamination of soil and groundwater due to sewage leakage, and voids in the ground. As a result, it may cause a sinkhole, resulting in personal injury and property damage.

In addition, serious environmental pollution may be caused by inflow of an unpurified wastewater discharged from a wastewater discharge pipe that is not properly maintained or discharged to a river.

Accordingly, in order to regularly determine whether the buried pipe is damaged, whether soil deposits and cement pool flow, determine the appropriateness of construction, and whether there is an obstacle to flow, it is generally limited by manpower through the inside of the manhole buried at a certain distance. It is equipped to be managed.

However, there may be cracks already generated inside the buried pipe, and there is a possibility that harmful gases remain. In this way, the input of manpower to the site for maintenance while the internal situation of the buried pipe is not accurately determined can cause personal injury.

In addition, when the internal situation of the buried pipe is not accurately determined, the introduction of a robot such as a self-propelled car instead of a person may cause property damage due to the loss of the robot.

In particular, a flow meter and a gas concentration meter (hereinafter, referred to as a meter) are installed in wastewater pipes that are difficult to manage due to manual input of manpower. However, in order to avoid fines and fines arising from the discharge of wastewater, cases in which outsiders are caught by unauthorized manipulation of the measuring instrument are steadily occurring. As such, there is an increasing number of cases where the conditions of buried pipes, which are difficult to identify with the naked eye, are abused and damaged and occupied without permission during redevelopment/reconstruction and underground burial pipe construction such as gas pipes and power pipes.

Hereinafter, a preferred embodiment of the buried pipe monitoring apparatus 100 according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing an upper portion of a buried pipe 1 in which a buried pipe monitoring device 100 is installed according to the present invention, and FIG. 2 is a buried pipe 1 in which the buried pipe monitoring device 100 shown in FIG. It is a partial cross-sectional view showing the upper part of, and FIG. 3 is an exploded perspective view of the buried pipe monitoring apparatus 100 shown in FIGS. 1 to 2.

As shown, the buried pipe monitoring device 100 includes an external connection pipe 110, a fixed plate ring 130, a load support member 140, a camera dome 150, a camera 160, and a flexible pipe 170. Include.

The external connection pipe 110 is a straight pipe of a set height that is coupled through the upper side of the buried pipe 1.

The fixed plate ring 130 is fitted to the external connection pipe 110, and is disposed on the outer peripheral surface of the buried pipe 1 to be bolted. The fixed plate ring 130 provides a flat surface to the curved buried pipe 1 so that the load support member 140 and the auxiliary support member 180 to be described later can stably support the external connection pipe 110.

The load supporting members 140 are arranged in a pair to face each other, one side is coupled to the outer peripheral surface of the external connection pipe 110, the other side is coupled to be seated on the upper surface of the fixed plate ring 130. Therefore, it is formed to prevent the external connection pipe 110 from falling into the buried pipe 1 due to a load.

The camera dome 150 is disposed inside the bottom surface of the external connection pipe 110, that is, the upper side of the buried pipe 1. It is preferable that the camera dome 150 is coupled to the bottom of the external connection pipe 110 by clamping or bolting to enable opening and closing. The camera dome 150 may be in the shape of a rectangular parallelepiped or cylindrical, but it is formed in the form of a dome in order to better absorb the shock that may be received from the buried pipe (1) internal flow rate or high flow rate. desirable. In particular, the camera dome 150 is made of a material such as PVC that is a transparent material and has good corrosion resistance so as to facilitate the vision of the camera 160. In addition, by attaching an anti-fog film to the outer surface to have a waterproof and anti-fog effect, the camera 160 can secure a clear view.

The flexible pipe 170 is preferably formed of a corrugated pipe capable of freely expressing curves and straight lines so that it can be freely connected from the external connection pipe 110 to the ground. One side of the flexible pipe 170 is connected to the upper part of the external connection pipe 110, and the other side is connected to the ground. If the distance between the buried pipe 1 and the ground is far, or if the flexible pipe 170 is required more than a set distance due to obstacles, it may be provided as one flexible pipe 170, but at least one flexible pipe 170 is provided. It can also be provided by connecting.

As for the camera 160, all types of cameras 160 capable of monitoring the state of the buried pipe 1 can be selected, and are installed inside the camera dome 150. In addition, by using a camera 160 of a size that can pass through the inside of the external connection pipe 110 and the flexible pipe 170, the camera 160 through the external connection pipe 110 and the flexible pipe 170 It can be configured for immediate collection and relocation. In addition, the camera dome 150 may be configured with the same diameter as the external connection pipe 110. Therefore, when installing and separating the buried pipe monitoring device 100 in the buried pipe 1, there is an advantage that the camera dome 150 can be collected from the outside without the need for human resources to be put into the buried pipe 1.

In addition, it is preferable that the bushing 120 is coupled between the external connection pipe 110 and the buried pipe 1. The bushing 120 may firmly connect the external connection pipe 110 and the buried pipe 1 by removing the clearance between the external connection pipe 110 and the buried pipe 1. Therefore, it is preferable that the bushing 120 is made of an elastic rubber material. In addition, it is possible to protect the buried pipe 1 monitoring device 100 by absorbing vibrations caused by fluid movement on the road where the buried pipe 1 is buried or inside the buried pipe 1.

In addition, when the diameter of the camera dome 150 is larger than the external connection pipe 110, the buried pipe 1 may be penetrated so that the camera dome 150 can pass. In this way, when the clearance between the external connection pipe 110 and the hole penetrating through the buried pipe 1 increases, the bushing 120 corresponding to the clearance value may be coupled. Accordingly, it is possible to install or collect the camera dome 150 from the outside of the buried pipe 1. Accordingly, there is an advantage that it is very safe because it is not necessary to input manpower inside the buried pipe 1, and at the same time, the maintenance cost can be drastically reduced.

FIG. 4 is an enlarged perspective view of part “A” shown in FIG. 1.

As shown, the buried pipe monitoring device 100 includes an external connection pipe 110, a camera dome 150, and a camera according to necessity such as the diameter of the buried pipe 1 and the distance from the ground to the buried pipe 1 160) and the flexible pipe 170 may be enlarged. In this case, it is preferable to further include an auxiliary support member 180 that assists the load support member 140 for supporting the load of the buried pipe monitoring device 100. The load supporting member 140 and the auxiliary supporting member 180 will be described in detail below.

5 is an exploded perspective view of the load supporting member 140 shown in FIGS. 1 to 4.

As shown, the load supporting member 140 includes a positioning unit 141, a rod unit 143, a load distribution unit 145, and a stopping bolt 147.

First, on the outer circumferential surface of the external connection pipe 110, a pair of rails 111 that are disposed to face each other and adjacent to the buried pipe 1 are coupled.

The positioning unit 141 is coupled to slide along the rail 111 so that the load support member 140 finds a suitable position to support the load of the external connection pipe 110.

The load unit 143 is hinged on one side of the positioning unit 141 to distribute the load of the external connection pipe 110 to the other side.

The load distribution unit 145 is hinged to the other side of the rod unit 143 and is seated on the upper surface of the fixed plate ring 130 to distribute the load received from the rod unit 143 toward the fixed plate ring 130. The load distribution unit 145 is a principle that is fixed by a tie of internal pressure and external pressure. In order to maximize the effect of this principle, the load distribution unit 145 is formed in a cone shape. When the load of the external connection pipe 110 transmitted through the rod unit 143 presses the load distribution unit 145, the air between the load distribution unit 145 and the upper surface of the fixed plate ring 130 exits and is sealed. . Accordingly, the internal pressure of the load distribution unit 145 is lower than the external pressure. Therefore, the external connection pipe 110 is stably supported by the force pressed by the load and external pressure of the external connection pipe 110. In order to fully maintain the strong adsorption force with this principle, it is preferable to be fixed to the upper surface of the flat fixed plate ring 130 rather than the outer peripheral surface of the curved buried pipe.

When the positions of the positioning unit 141 and the load distribution unit 145 are determined, the stopping bolts 147 disposed on the upper or lower side of the positioning unit 141 are coupled with the nut. Therefore, the positioning unit 141 prevents the slide movement. The stopping bolt 147 may be provided with one bolt and a nut formed of a bolt head corresponding to the inner size of the rail 111 in pairs. In addition, it may be provided with a pair of nuts and stud bolts formed of nuts corresponding to the inner size of the rail. At this time, the rail 111 is preferably provided with a T-shaped rail. Therefore, one side corresponding to the head of the stopping bolt 147 can slide along the inside of the rail 111, and the other side exposed to the outside of the rail 111 is nut-coupled. That is, when the nut on the outside of the rail 111 is tightened at a required position, the outer surface of the rail 111 is tightened and is fixed to the set position. Accordingly, the positioning unit 141 and the load distribution unit 145 can be stably fixed.

This prevents the external connection pipe 110 from falling into the buried pipe 1 due to gravity and load. In general, when the positioning unit 141 is positioned above the position of the load distribution unit 145, it is preferable to couple the stop bolt 147 to the lower side of the positioning unit 141. In addition, when the positioning unit 141 is located below the height of the load distribution unit 145, it is preferable to couple the stop bolt 147 to the upper side of the positioning unit 141.

6 is an exploded perspective view of the auxiliary support member 180 shown in FIGS. 1 and 3 to 4.

As shown, the auxiliary support member 180 includes a housing 181, a support plate spring 182, a screw rod 183, an auxiliary fixing part 184, and an elastic spring 185. The housing 181 is formed as a cylinder with an open side of the external connection pipe 110. The other surface is formed through a tab or a nut is coupled so that the screw rod 183 can move forward and backward along the thread. The housing 181 is preferably mounted on the support plate spring 182 so as to be spaced apart from the upper surface of the fixed plate ring 130 by a set distance. The support plate spring 182 is formed to absorb the vibration by shaking together with a constant vibration when more than a set force is applied to the housing 181. Therefore, it serves as a suspension that cancels the vibration of the set force that can reach the external connection pipe 110 side.

The auxiliary fixing part 184 is coupled to the external connection pipe 110 side end of the screw rod 183. The auxiliary fixing part 184 is detachable from the external connection pipe 110 by moving the screw rod 183 forward and backward with an elastic material. When the screw rod 183 advances, pressure is applied to the auxiliary fixing part 184 in the direction toward the external connection pipe 110. The elastic spring 185 is inserted into the screw rod 183 and is seated in the housing 181. The elastic spring 185 presses the upper surface of the auxiliary fixing part 184 with a property to be tensioned, so that the auxiliary support member 180 can support the external connection pipe 110 more firmly.

The buried pipe monitoring device 100 may be installed during the construction process of burying the buried pipe 1, and may be installed for maintenance and inspection of the buried pipe 1 during the construction process. In addition, it may be additionally installed for maintenance and inspection of the already installed buried pipe (1). This buried pipe monitoring device 100 is a material corresponding to the material of the buried pipe 1, such as concrete, after the construction is completed, or when collected as necessary, the buried pipe 1 penetrated for installing the camera dome 150 The advantage is that it can be restored to its original state by filling or covering it.

7 is a front view of a buried pipe monitoring apparatus 100 in which a camera dome 150 having a jet hole 151 and a measuring instrument hole 152 shown in FIGS. 2 to 3 is installed.

As shown, in the camera dome 150, the camera 160 may not be able to capture a clear internal image due to internal factors such as water droplets, moisture, or misting while the fluid in the buried pipe 1 moves. have. Accordingly, the buried pipe monitoring apparatus 100 may further include a wiper 190 and a washer liquid injection unit (not shown).

The wiper 190 wipes the area of the camera dome 150 corresponding to the shooting angle of the camera 160.

The washer liquid injection unit includes a washer liquid tank (not shown), a washer liquid pipe (not shown), and an injection port (not shown). The washer liquid pipe moves the washer liquid from the external washer liquid tank to the injection port corresponding to the camera dome 150. The camera dome 150 is provided with a jet hole 151 to allow the jet hole to pass through an area adjacent to the wiper 190. The injection port sprays the washer liquid onto the camera dome 150 corresponding to the operating area of the wiper 190 through the injection hole hole 151. The control wiring (not shown) of the washer liquid pipe and the injection port is discharged through the external connection pipe 110 and the flexible pipe 170 and can be managed and supervised by the control box (B).

The washer liquid contains a surfactant that can remove oil, acts as a preservative to prevent water and water from spoiling, and contains alcohol to prevent water from freezing. Accordingly, there is an effect of removing fogging and moisture from the camera dome 150.

Further, the camera 160 may be an infrared camera 160 as necessary, but a general camera 160 may be used. In the case of using the general camera 160, a light unit (not shown) may be additionally included to illuminate the interior of the buried pipe 1.

The control box (B) is installed adjacent to the ground, and the control and power wiring (w) of the camera 160, the wiper 190, the washer liquid injection unit and the light unit are collected. The control center (not shown) connects to the control box B through wired/wireless communication and controls and manages the camera 160, the wiper, the washer liquid spraying unit, and the light unit in an integrated manner. One control center may control one or more control boxes B, and one or more control centers may manage and control the buried pipe monitoring apparatus 100 of a wider area.

In addition, the buried pipe monitoring device 10 may further include a flow meter, a water level sensor, and a gas concentration meter (hereinafter, referred to as a meter). The camera dome 150 is provided with a measuring device hole 152 in an area adjacent to the wiper 190 to allow a measuring device (not shown) to pass therethrough. Therefore, the wiring of the measuring device is discharged through the external connection pipe 110 and the flexible pipe 170 so that management and supervision in the control box (B) is possible. The control center primarily collects data values through a measuring device for the internal state of the buried pipe 1. Then, the value collected from the measuring device and the actual image inside the buried pipe 1 collected in real time through the camera 160 are compared and analyzed.

The measuring instrument may transmit data values different from the actual situation due to some factors such as water droplets or temporary increase in flow velocity. However, by comparing the real-time internal situation with the camera 160 as described above and reducing an error between the data value and the actual situation, unnecessary maintenance expenses can be prevented.

In particular, in the case of installing the buried pipe monitoring device 100 in addition to the wastewater discharge pipe (1) of a wastewater producer, it acts as a CCTV (Closed Circuit Television) to prevent unauthorized manipulation of the installed measuring device. have. Therefore, it is possible to drastically reduce the manpower and on-site inspection costs that are input for reasons such as emergency inspection.

This means that the buried pipe monitoring device 100 is installed so that unauthorized damage and unauthorized occupation that may occur in the future can be blocked at the source.
