At this time, the support 160 is a support protrusion 157 in a state that the first flange 131 is in close contact with the second flange 153, the horizontal portion of the discharge pipe 130 and the elbow portion 155 is located in a straight line. ), It is possible to facilitate the coupling of the discharge pipe 130 and the pump assembly 150 in the form of simply mounting the support protrusion 157 in the seating groove 161.

In addition, when the first flange 131 and the second flange 153 are in close contact with each other, the first bent portion 132 formed on the first flange 131 and the second bent portion 154 formed on the second flange 153 are provided. ) Can be in contact with each other to distribute the load of the second flange 153 to the discharge pipe 130 and at the same time can prevent the second flange 153 from moving to the lower side of the same line of the first flange 131. .

Therefore, the discharge pipe 130 and the pump assembly 150 is coupled to the upper portion located on the water surface to easily check the leakage of the connection portion, and facilitate the coupling of the discharge pipe 130 and the pump assembly 150. It can be effective.

In addition, there is no need to configure the anchoring work or a separate installation device to fix the submersible pump 151 as in the prior art has an effect that can significantly reduce the manufacturing cost.

Although the embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and it is recognized that the present invention is easily changed and equivalent by those skilled in the art to which the present invention pertains. Includes all changes and modifications to the scope of the matter.
