Description

A monitoring device for collecting information inside a buried pipe {the Device for Monitoring Buried Pipe}

The present invention collects the information in the buried pipe through the information collection unit of the monitoring device installed inside the buried pipe and transmits it to the control center on the ground, so that the efficient maintenance of the buried pipe is performed, thereby reducing the maintenance cost. It relates to a monitoring device for collecting information inside the tube.

The buried pipe includes a sewage pipe for collecting sewage and rainwater and transporting it to the sewage treatment plant and discharge area, and determines the drainage area and treatment area to form a sewage pipe network underground. In addition, the buried pipe includes a buried wastewater discharge pipe to discharge the wastewater produced by the wastewater producer.

If such a buried pipe is not continuously maintained and managed, the function of the sewage treatment facility deteriorates due to aging and cracks occur, the soil and cement paste of the ground layer covering the buried pipe will flow into the buried pipe. can be imported.

In addition, the transport function is weakened by the soil and organic sediment flowing into the buried pipe, so that rainwater overflows, soil and groundwater contamination due to sewage leakage, and cavities may occur in the ground. Due to this, it may cause a sinkhole, which may cause personal injury and property damage.

In addition, it may cause serious environmental pollution due to the inflow of wastewater that has not been purified or more than an appropriate amount discharged from a wastewater discharge pipe that is not properly maintained.

Accordingly, in order to regularly determine whether the buried pipe is damaged, whether internal soil is deposited and whether the cement pool is inflowed, to determine the adequacy of construction and whether there is a flow obstruction, generally through the inside of the manhole buried at a certain distance, limited by manpower set up to be managed.

However, there may be cracks that have already been created inside the buried pipe, and there is a possibility that harmful gases may remain. In this way, the input of manpower on the site for maintenance in a state where the internal condition of the buried pipe is not accurately judged can cause casualties.

In addition, in a state where the internal condition 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 robot loss.

In particular, a flow rate meter and a gas concentration meter (hereinafter referred to as a meter) are installed in wastewater pipes, which are difficult to manage because manpower is input one by one. However, in order to avoid fines and negligence caused by the discharge of wastewater, cases in which an outsider manipulates the measuring device without permission are constantly occurring. As such, there is an increasing number of cases of unauthorized damage and occupation of underground pipes such as gas pipes and power pipes by exploiting the conditions of the buried pipes that are difficult to grasp with the naked eye.

(Example 1)

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

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 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 circumferential surface of the buried pipe 1 and is bolted together. 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 pairs to face each other, one side is coupled to the outer circumferential surface of the external connection pipe 110 , and the other side is coupled to be seated on the upper surface of the fixing plate ring 130 . Therefore, it is formed to prevent the external connection pipe 110 from falling into the buried pipe (1) due to the load.

The camera dome 150 is disposed inside the lower surface of the external connection pipe 110 , that is, the upper side of the buried pipe 1 . The camera dome 150 is preferably coupled to the lower surface 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 cuboid or a cylinder, but it is formed in the form of a dome in order to absorb the shock that can be received from a high flow rate or a high flow rate inside the buried pipe 1 . desirable. In particular, the camera dome 150 is made of a transparent material so that it is easy to secure the vision of the camera 160, and a material such as PVC with good corrosion resistance is applied. In addition, by attaching an anti-fog film to the outer surface to have a waterproof and anti-fogging effect, the camera 160 can secure a clear view.

The flexible pipe 170 is preferably formed of a corrugated pipe capable of freely expressing bends 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. When the distance between the buried pipe 1 and the ground is long or the flexible pipe 170 is required more than a set distance due to an obstacle, it may be provided as one flexible pipe 170, but one or more flexible pipes 170 are used. It can also be provided by connecting.

All types of cameras 160 capable of monitoring the state of the buried pipe 1 are selectable, and the camera 160 is installed inside the camera dome 150 . In addition, 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 from the outside It can be configured for immediate collection and redeployment. In addition, the camera dome 150 may be configured to have 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 it is possible to collect the camera dome 150 from the outside, without the need for manpower to be input 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 in which 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 to allow the camera dome 150 to pass therethrough. As such, when the clearance between the external connection pipe 110 and the hole penetrated in the buried pipe 1 is increased, the bushing 120 corresponding to the clearance value can be coupled. Therefore, the camera dome 150 can be installed or collected from the outside of the buried pipe 1 . Accordingly, there is an advantage that it is very safe because the input of manpower inside the buried pipe 1 is unnecessary, and at the same time, the maintenance cost can be dramatically reduced.

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

As shown, the buried pipe monitoring apparatus 100 includes an external connection pipe 110, a camera dome 150, a camera ( 160) and the flexible pipe 170 may be large. 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 support member 140 and the auxiliary support 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 support member 140 includes a positioning unit 141 , a rod unit 143 , a load distribution unit 145 , and a stop bolt 147 .

First, on the outer peripheral surface of the external connection pipe 110, disposed to face each other, a pair of rails 111 adjacent to the buried pipe (1) is coupled.

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

The rod part 143 is hinge-coupled to the positioning part 141 and one side, and distributes 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 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 part 143 presses the load distribution part 145, the air between the load distribution part 145 and the upper surface of the fixed plate ring 130 escapes the set amount and is sealed. . Accordingly, the internal pressure of the load distribution unit 145 is lower than the external pressure. Accordingly, the external connection pipe 110 is stably supported by the force applied by the load and external pressure of the external connection pipe 110 . In this principle, it is preferable to be fixed to the upper surface of the flat fixing plate ring 130 rather than the outer peripheral surface of the curved buried pipe in order to fully maintain the strong adsorption force.

When the positions of the positioning unit 141 and the load distribution unit 145 are determined, the stop bolt 147 disposed above or below the positioning unit 141 is coupled to the nut. Accordingly, the positioning unit 141 is prevented from sliding. The stop bolt 147 may be provided with a pair of one bolt and a nut formed with a bolt head corresponding to the internal size of the rail 111 . 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 as a T-shaped rail. Accordingly, one side corresponding to the head of the stop 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 fixed at the set position. Accordingly, it is possible to stably fix the positioning unit 141 and the load distribution unit 145 .

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 positioned 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 in a cylindrical shape with one side open on the external connection pipe 110 side. The other surface is formed through a tab or a nut is coupled to enable the screw rod 183 to move forward and backward along the thread. The housing 181 is preferably seated 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 to cancel the vibration of the set force that can reach the external connection pipe (110) side.

The auxiliary fixing part 184 is coupled to the end of the external connection pipe 110 side of the screw rod 183 . The auxiliary fixing part 184 is an elastic material and is detachably attached to the external connection pipe 110 by the forward and backward movement of the screw rod 183 . 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 inside the housing 181 . The elastic spring 185 presses the upper surface of the auxiliary fixing part 184 in a tensile property, so that the auxiliary support member 180 can more firmly support the external connection pipe 110 .

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). Such a buried pipe monitoring device 100 is a material corresponding to the material of the buried pipe 1, such as concrete, for the installation of the camera dome 150 after completion of construction, or upon collection as needed. It has the advantage that it can be restored to its original state by filling or covering it.

7 is a front view of the buried pipe monitoring apparatus 100 in which the camera dome 150 provided with the injection hole 151 and the measuring device hole 152 shown in FIGS. 2 to 3 is installed.

As shown, in the camera dome 150, there may be cases where the camera 160 cannot take a clear internal image due to internal factors such as water droplets, moisture, or steaming splashing 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 fluid spraying 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 fluid pipe moves the washer fluid from the external washer fluid tank to the injection port corresponding to the camera dome 150 . The camera dome 150 is provided with an injection hole 151 to allow the injection hole to pass through the area adjacent to the wiper 190 . The injection port injects the washer fluid into the camera dome 150 corresponding to the operation area of the wiper 190 through the injection 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 so that the control unit C can manage and supervise it.

Washer fluid contains a surfactant that can remove oil, water and alcohol to prevent water from decaying and act as a preservative to prevent water from freezing. Accordingly, there is an effect of removing fogging and moisture of the camera dome 150 .

In addition, as the camera 160 , an infrared camera 160 may be used as needed, but a general camera 160 may be used. When the general camera 160 is used, a light unit (not shown) may be additionally included to illuminate the inside of the buried pipe 1 .

The control unit (C) is installed adjacent to the ground, and the control and power wiring (w) of the camera 160, the wiper 190, the washer fluid injection unit and the light unit are collected. The control center (not shown) is connected to the control unit C through wired/wireless communication to control and manage the camera 160, the wiper, the washer fluid injection unit, and the light unit in an integrated manner. One control center may control one or more control units C, and one or more control centers may manage and control the buried pipe monitoring apparatus 100 in 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 so that a measuring device (not shown) can pass therethrough. Therefore, the wiring of the measuring instrument is discharged through the external connection pipe 110 and the flexible pipe 170, so that the control unit C can manage and supervise it. 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 meter may transmit data values different from the actual situation due to some factors such as water droplets or a temporary increase in flow rate. However, by reducing the error between the data value and the actual situation as compared with the real-time internal situation through the camera 160, unnecessary maintenance expenditure can be prevented.

In particular, if the buried pipe monitoring device 100 is additionally installed in the wastewater discharge pipe (1) of the wastewater producer, it acts as a CCTV (Closed Circuit Television) to prevent unauthorized manipulation of the previously installed measuring device by an outsider. have. Therefore, it is possible to significantly reduce the cost of manpower and on-site inspection for reasons such as unplanned inspection.

This has the effect of preventing unauthorized damage and unauthorized occupation that may occur in the future by installing the buried pipe monitoring device 100 .
