EXAMPLE

Fig. 2 is a reference diagram showing water turning using the water jetting device and water turning method according to the present invention.

As shown, according to the water jetting apparatus and the water spinning method according to the present invention, the water jetting lake 140 is not installed via the ground, but is an intermediate pipeline (P1) that is subject to camera shooting and repair work. It is configured to pass through as it is. The present invention does not require a separate pump for pumping sewage by such a configuration, and the installation and dismantling of the rotatable lake 140 becomes very simple and quick.

Hereinafter, the configuration of the present invention will be described in detail. However, the water jetting apparatus of the present invention will be described first, followed by the water turning method.

 3 is a perspective view of a water dispenser according to the present invention, and FIG. 4 is an exploded perspective view of the water dispenser according to the present invention.

As shown, the water jet device of the present invention comprises an outlet pipe 110, air tube 120, opening and closing means 130.

The outlet pipe 110 has a body in the form of a pipe that can flow sewage. The front end portion 110A of the outlet pipe 110 is preferably stepped to a smaller outer diameter so that the rotatable lake 140 can be easily connected. The outer peripheral surfaces of the front end portion 110A and the rear end portion 110B of the outlet pipe 110 are respectively joined to the disk-shaped support members 115 and 117 having a through hole at the center thereof. The disc-shaped support members 115 and 117 support both sides of the disc-shaped support member 115 and 117 so that the air tube 120 installed on the outer circumferential surface of the disc tube 110 is not separated from the gap. It also serves to prevent sewage from spilling. In addition, the air tube 120 also serves to guide the stable contraction and expansion toward the inner wall of the pipe.

The air tube 120 is installed on the outer circumferential surface of the outlet pipe 110 and expands when air is injected to serve to seal tightly between the inner wall of the pipe and the outlet pipe 110. To this end, the air tube 120 has a through hole formed along the longitudinal direction in the center of the outlet tube 110 to be fitted in the center. The outer circumferential surface of the air tube 120 has a plurality of index wrinkles 121 protruding along the circumferential direction. The index wrinkles 121 prevent the sewage leaking between the air tube 120 and the pipe when air is injected into the air tube 120 and expanded.

The opening and closing means 130 is installed at the rear end 110B of the outlet pipe 110 to open and close the inlet 113 formed at the rear end 110B of the outlet pipe 110. To this end, the opening and closing means 130 has a pair of pneumatic cylinders (131, 133) and the opening and closing plug 135 advancing by the pneumatic cylinder (131, 133) as a main component.

The pneumatic cylinders 131, 133 are known as consisting of a cylinder body 131 and a piston 133 advancing backwards from the cylinder body 131. The cylinder body 131 is fixedly installed on both sides of the outlet end 110B. The cylinder piston 133 advances the opening and closing plug 135 coupled to the end by the connecting member 137.

The opening and closing stopper 135 is formed in a circular shape to close and close the inlet 113 of the rear end 110B of the outlet pipe (110). Here, the rear portion of the opening and closing stopper 135 is formed in a conical shape that gradually narrows its width to offset the resistance due to the flow rate as much as possible in the flow of sewage. On the other hand, the opening and closing plug 135 is in close contact with the opening and closing plug 135 at the end of the rear end 110B of the outlet pipe 110 so as to further close the rear inlet 113 of the outlet pipe 110. It is preferable that a seating ring 136 (see FIG. 3) is provided to increase the area.

On the other hand, the coupling method of the outlet pipe 110 and the rotatable lake 140 is preferably a snap-lock (snap-lock) method that can be combined and separated at once.

5 and 6 are operation explanatory diagrams for explaining the operation of opening and closing the water purifying device according to the present invention.

As shown in the drawing, the opening and closing stopper 135 coupled to the piston 133 of the retracting cylinder selectively opens and closes the inlet 113 of the outlet pipe 110. That is, when the piston 133 of the cylinder withdraws from the rear as shown in FIG. 5, the opening and closing stopper 135 closes and closes the inlet 113 of the outlet pipe 110, and the piston 133 of the cylinder is closed as shown in FIG. 6. When it is advanced to the rear, the inlet 113 of the outflow pipe 110 is opened while the sewage flows out through the outflow pipe 110 and flows on the lake 140 for water turning.

Subsequently, the water turning method according to the present invention will be described with reference to FIGS. 7 to 9. 7 to 9 are reference views for explaining the water turning method according to the present invention.

Subsequently, a step of installing a water turning lake 140 connecting the outlet pipe 110 and the downstream pipe line P3 to form the outlet port via the inside of the intermediate pipe line P1 is performed. To this end, the rotatable lake 140 is dripped so that both ends thereof reach the upstream manhole M1 and the downstream manhole M2 via the intermediate pipe P1. Then, the upstream end of the water jetting lake 140 is coupled to the front end 110A of the outlet pipe 110 of the water jet device. The water jetting lake 140 and the front end portion 110A of the outlet pipe 110 are coupled at a time by a snap lock method.

Subsequently, when the piston 133 of the cylinder is advanced to the rear as shown in FIG. 9, the opening and closing plug 135 which blocks the inlet of the outlet pipe 110 is advanced to the rear to open the outlet pipe 110. Then, the sewage (W) filling upstream in the upstream pipe (P2) is discharged through the outlet pipe 110 is opened and is discharged into the downstream pipe (P3) along the rotatable lake 140. This completes the installation work for watering.
