The present invention relates to a water pipe cleaning device using ultrasonic vibration, and more specifically, to a water pipe cleaning device using ultrasonic vibration that can improve scale removal performance inside the water pipe.

In general, when water pipes that supply tap water are used for a long time after installation, they age and various foreign substances contained in tap water are deposited on the inside of the pipe as sludge or the inside of the pipe is oxidized, forming rust, etc., and these solidify to form scale. A (scale) layer is formed.

As described above, the scale layer formed by the accumulation of foreign substances on the inner surface of the water pipe gradually thickens and solidifies over time, which has the problem of interfering with the smooth flow of water and lowering the water pressure. In addition, the attached scale Because the layer dissolves in water and causes water contamination, water pipes must be cleaned periodically.

In addition, problems caused by aging water pipes not only cause significant disruption in maintaining the function of the water pipe network, but also lead to significant increases in energy consumption. Therefore, in order to solve problems such as corrosion products and damage to water pipes, improvement work (cleaning or rehabilitation) is carried out on old water pipes. The methods applied to such pipe improvement work include cleaning and lining to clean the inside of the pipe. This is representative.

In particular, several methods have been proposed and used to remove the scale layer deposited on the inner surface of water pipes in the cleaning method. Among them, the commonly used cleaning methods are the flushing method, which releases settled sediments by increasing the flow rate inside the pipe, and the pulsation flow cleaning method, which cleans the inside of the pipe by creating turbulence using air bubbles.

Hereinafter, a water pipe cleaning device according to an embodiment of the present invention will be described with reference to the drawings.

Figure 1 is a diagram schematically showing a water pipe cleaning device 1 according to an embodiment of the present invention, and Figure 2 is a diagram schematically showing another embodiment of the water pipe cleaning device 1 shown in Figure 1. It is a drawing, and FIG. 3 is a drawing for explaining the operation of the water pipe cleaning device 1 shown in FIG. 2.

Referring to Figures 1 to 3, the water pipe cleaning device 1 according to an embodiment of the present invention includes an ultrasonic vibration module 10, a connection cable 20, and a controller 30. The ultrasonic vibration module 10 is inserted into the water pipe according to the flow rate of the fluid flowing through the water pipe. The ultrasonic vibration module 10 generates ultrasonic waves to relieve scale formed on the inner peripheral surface of a water pipe from falling off or adhering to the water pipe.

The connection cable 20 is connected to the ultrasonic vibration module 10. The controller 30 is connected to the connection cable 20. The controller 30 can control the operation of the ultrasonic vibration module 10. The controller 30 is placed outside the water pipe.

A front drain valve (4) and a rear drain valve (5) may be disposed in the water pipe. The front water valve (4) and the rear water valve (5) are spaced apart by a predetermined distance along the longitudinal direction of the water pipe. The rear sump valve (5) can be blocked. The front water valve (4) is open so that fluid (water) can flow through the water pipe. Although not shown in the drawing, the peripheral discharge valve connected to the water pipe is blocked. As a result, the flow rate of the fluid flowing through the water pipe can be increased. The ultrasonic vibration module 10 is inserted into the water pipe between the front water control valve (4) and the rear water control valve (5). Additionally, the fire hydrant (3) is connected between the front water drain valve (4) and the rear water drain valve (5).

In one embodiment, the ultrasonic vibration module 10 may include an ultrasonic vibrator 100. The ultrasonic vibrator 100 is connected to the connection cable 20. Ultrasonic vibrators 100 may be arranged in plural numbers. The ultrasonic vibrator 100 can generate ultrasonic waves to remove scale formed on the inner peripheral surface of a water pipe or weaken the adhesion strength. A plurality of ultrasonic vibrators 100 may be connected to the connection cable 20 at equal intervals. As a result, balanced ultrasonic waves are generated over the entire length from the first ultrasonic vibrator 100 arranged first of the plurality of ultrasonic vibrators 100 to the nth ultrasonic vibrator 100 arranged last (n is a natural number of 2 or more). can occur.

The connection cable 20 may penetrate the center of the ultrasonic vibrator 100. To this end, the ultrasonic vibrator 100 may have a central hole extending along the longitudinal direction of the water pipe. The connection cable 20 may penetrate the center hole of the ultrasonic vibrator 100. As a result, the vibration of the ultrasonic vibrator 100 is generated uniformly in the circumferential direction, and the generated vibration can uniformly reach the inner peripheral surface of the water pipe in the circumferential direction. The ultrasonic vibrator 100 may be connected to a conductive wire included in the connection cable 20. Thereby, the operation can be controlled by the controller 30.

The ultrasonic vibration module 10 may further include a flow propellant 120. The flow propellant 120 is connected to the connection cable 20. The connection cable 20 may penetrate the center of the flow propellant 120. For this purpose, the flow propulsion body 120 may have a central hole extending along the longitudinal direction of the water pipe at its center. The connection cable 20 may pass through the center hole of the flow propellant 120. Therefore, depending on the flow of fluid (water pipe), the flow propellant 120 may be located on the central axis of the water pipe. Accordingly, a plurality of ultrasonic vibrators 100 can also be arranged on the central axis of the water pipe.

The flow propulsion body 120 may include a front portion 121 and a rear portion 122. The front portion 121 faces the ultrasonic vibrator 120 and may be parallel to the cross section of the water pipe. In cross-section, the front portion 121 of the water pipe may have a circular shape. The rear portion 122 may extend from the front portion 121 along the longitudinal direction of the water pipe. The rear portion 122 may have a convex curved surface facing forward from the front portion 121. That is, the rear portion 122 may have a streamlined shape. As a result, fluid (water) passing between the front part 121 and the inner peripheral surface of the water pipe can flow smoothly along the curved surface of the rear part 122. Accordingly, the vibration of the flow propeller 120 is suppressed by the fluid passing through the flow propellant 120, and the flow propellant 120 can be stably positioned on the central axis of the water pipe. The cross-sectional area of the front portion 121 of the water pipe may be larger than the cross-sectional area of the ultrasonic vibrator 100. As a result, the flow propulsion body 120 can secure sufficient resistance due to the flow velocity.

The flow propeller 120 can be moved in the longitudinal direction of the water pipe by the flow rate generated by water discharge through the fire hydrant 3. In addition, the flow velocity propeller 120 can be maintained on the central axis of the water pipe as water is discharged through the fire hydrant 3.

Figure 4 is a diagram schematically showing another embodiment of the flow-velocity propulsion body 120 shown in Figure 2.

Referring to Figure 4, the flow propulsion body 120 may have a parachute shape. The parachute-shaped flow propellant 120 can secure sufficient buoyancy due to the flow speed. Therefore, even if a plurality of ultrasonic vibrators 100 are installed, the plurality of ultrasonic vibrators 100 can be placed on the central axis of the water pipe by the flow propeller 100.

In one embodiment, the flow propulsion body 120 may include an inner body 121 and an outer body 122. The inner body 121 may be obliquely extended to have a first angle with respect to the central axis of the water pipe. Additionally, the outer body 122 may be obliquely extended to have a second angle greater than the first angle with respect to the central axis of the water pipe. Thereby, a large lifting force can be secured.

Figure 5 is a diagram illustrating a water pipe cleaning method according to an embodiment of the present invention.

Referring to Figures 1 to 5, the water pipe cleaning method according to an embodiment of the present invention includes an insertion step (S10), a flow rate generation step (S20), an ultrasonic generation step (S30), a recovery step (S40), and a flushing step ( S50).

An ultrasonic vibration module 10 that generates ultrasonic waves inside the water pipe is inserted into the water pipe (S10). By generating a flow rate inside the water pipe, the ultrasonic vibration module 10 can be moved along the longitudinal direction of the water pipe (S20). Accordingly, the ultrasonic vibration module 10 can be naturally positioned on the central axis of the water pipe by the fluid.

The ultrasonic vibration module 10 generates ultrasonic waves inside the water pipe (S30). The controller 30 may operate or stop the ultrasonic vibration module 10. Additionally, the controller 30 can adjust the degree of operation of the ultrasonic vibration module 10. The ultrasonic vibration module 10 can be recovered from the water pipe (S40). That is, the ultrasonic vibration module 10 may be discharged to the outside of the water pipe. By generating a flow rate inside the water pipe, the inside of the water pipe can be cleaned (S50). By this, the scale that has fallen off from the inner peripheral surface of the water pipe can be disposed. Additionally, scale with weakened adhesion to the inner peripheral surface of the water pipe may fall off due to the flow rate.

In the flow rate generation step (S20), the flow rate inside the water pipe may be generated by discharge of water through the fire hydrant (3). Additionally, in the flushing step (S50), the flow rate inside the water pipe may be generated by discharge of water through the fire hydrant (3). It may be lower than the flow rate in the flow rate generation step (S20) and the flow rate in the flushing step (S50). In the flushing step (S50), water can be flowed into the water pipe to clean the water pipe. In another example, a water pipe may be cleaned with a pulsating flow device.

Additionally, the ultrasonic generation step (S30) may include a flow rate reduction step and an image confirmation step. In the flow rate reduction step, the flow rate can be reduced by reducing the discharge of water through the fire hydrant (3). As a result, ultrasonic waves through the ultrasonic vibrator 100 can be sufficiently applied to the scale attached to the inner peripheral surface of the water pipe. The recovery step (S40) may further include a flow rate stopping step. In the flow stop stage, the flow rate inside the water pipe can be stopped by stopping the discharge of water through the fire hydrant (3). As a result, the ultrasonic generation module 10 inserted inside the water pipe can be easily discharged from the water pipe.

Although the invention made by the present inventor has been described in detail according to the above-mentioned embodiments, the present invention is not limited to the above-described embodiments and, of course, can be changed in various ways without departing from the gist of the invention.
