Temporary drainer for reserved opening on balcony

Abstract

The present invention provides a temporary hydrophobic device for a reserved opening on a balcony. With a screw as the center, a hole positioning component, a bending frame, an inflatable water collecting trough, and a water outlet filter cylinder are assembled on the screw. Thus, the hydrophobic device of the present invention is positioned and clamped on the peripheral surface of the upper opening of the reserved opening by using the hole positioning component, so that the folding frame and the inflatable water collecting trough in the folded state, and the water outlet filter cylinder provided at the bottom end of the screw pass through the reserved opening. Then, by unfolding the folding frame and inflating the inflatable water collecting trough, the inflatable water collecting trough expands to form a conical trough with a stable structure and a trough opening closely attached to the bottom surface of the floor slab, so that the accumulated water directly falls into the inflatable water collecting trough after entering the reserved opening, or flows from the bottom surface of the floor slab to the inner wall of the trough opening of the inflatable water collecting trough and converges downward, and finally is discharged by the water outlet filter cylinder, achieving the effect of collecting the accumulated water and connecting it to a temporary water pipe for discharge, avoiding the disorderly flow of water, and improving the overall construction efficiency.

There are several rib strips 621 spaced and connected between the assembly groove 61 and the socket part 63. The rib strips 621 are spaced apart to form the water inlet 622 of the water outlet filter cylinder 60. The rib strips 621 and the water inlet 622 together form a water filtering part 62. Both the water filtering part 62 and the socket part 63 are internally hollow and communicate with each other, so that accumulated water enters the water filtering part 62 from the water inlet 622, then flows through the socket part 63, and finally is discharged from the water outlet hose 70 connected to the socket part 63.

[0035] Further, the assembly groove 61 is formed with a groove bottom plate connected to the top ends of the rib strips 621. The peripheral edge of the groove bottom plate bulges upward to form a circular peripheral wall. The groove bottom plate and the peripheral wall together form the assembly groove 61 for inserting and accommodating the bottom end of the screw rod 20, so as to sleevedly install the water outlet filter cylinder 60 at the bottom end of the screw rod 20.

[0036] Further, the top and bottom of the rib strips 621 are bent toward the inside of the water outlet filter cylinder 60 respectively, so that the rib strips 621 form a vertically straight long middle section and connecting pieces at the top and bottom ends. Among them, the connecting piece at the top end of the rib strip 621 is integrally connected to the peripheral edge of the groove bottom plate of the assembly groove 61, and the connecting piece at the bottom end of the rib strip 621 is integrally connected to the top edge of the socket part 63.
