Description

Dredging device and method of rain gutter connector using automatic rotary nozzle by water pressure {Nozzle and Rain Gutter Connector Dredge and the Method using Nozzle}

The present invention relates to a rain gutter connecting pipe dredging device and method using an automatic rotary nozzle by water pressure, and more particularly, even if the working space is narrow can be dredged efficiently, and the pressure is divided into two directions It relates to a rain gutter connecting pipe dredging device and method using an automatic rotary nozzle by 360-degree rotary water pressure.

Most of the urban surface is paved with concrete or asphalt, so it is difficult for rainwater to seep through the ground. Therefore, rainwater gutters are installed at regular intervals along the roadside to allow rainwater to flow down to sewers and nearby rivers during the rainy season.

Generally, rain gutters are installed at intervals of 10 to 30 m along the roadside, and rain gutters are provided with connecting pipes to nearby sewers or rivers. The connecting pipe is composed of a length of about 2 ~ 10m depending on the position of the rain gutter and the sewer pipe, it is generally formed to be inclined downward so as to be lowered toward the sewer pipe from the rain gutter so that the natural drainage.

Rain gutters of the above-described configuration is used only in the case of rain, and is a facility rarely used in ordinary times. In addition, in rainy seasons such as rainy season, soil and leaves accumulated in the side of the road and alleys and / or household waste may be blocked at the same time with the rain water, so the connection pipe may be blocked.

In addition, even if the connection pipes are not blocked at once, the soils introduced with rainwater accumulate little by little in the connection pipes, and eventually the connection pipes are frequently blocked.

In particular, the soils introduced with rainwater are mixed very hardly with large grains to fine grains, so that the small grains are filled between the large grains, and the grains are slowly dried in a cool underground.

In this way, when the connection pipe connecting the rain gutter and the sewer pipe is blocked, the rainwater is not discharged smoothly and flooding damage occurs around. Therefore, it is necessary to check and clean the rain gutters and the connecting pipe periodically, and dredging if the connecting pipe is blocked by the soil.

On the other hand, as described above, the connection pipe of the rain gutter is generally inclined for natural drainage, and the soil piled up in the connection pipe is hardly hardened, so dredging is not easy, and the connection pipe is connected in multiple places at the same time. Because of the closure, a lot of manpower and money are required.

Conventional nozzles, on the other hand, are pipe-shaped mechanical parts used to determine the flow direction of a fluid such as gas or liquid.

That is, the nozzle is used to control the characteristics of the fluid, such as the flow rate, flow rate, direction, pressure of the flowing material.

However, the conventional nozzle is removed by spraying on the hardened soil material accumulated in the rain gutter connecting pipe, and it is difficult to dredge the soil solidified in the field because it is formed in a structure that cannot use the energy of the high pressure washing water properly. This is increasing.

In addition, as shown in FIG. 16, another conventional technology includes a method of rotating a motor by increasing the pressure of rotating water and rotating the motor by rotating the motor therein, but the power consumption and manufacturing process of the motor are complicated. The problem of high maintenance costs has occurred.
