The connecting strip 11 is made of rubber material, which is convenient for protecting the top of the drain outlet 1, making it difficult for impurities to fall into the inside of the drain outlet 1, avoiding the situation where the drain outlet 1 is blocked. The structure is simple, which is convenient for early workers to assemble and install, and is highly practical.

[0022] like Figure 2 and Figure 4As shown, connecting components are provided on both sides of the bottom of the water collecting bucket 2, and the connecting components include limit rods 12 symmetrically arranged on both sides of the bottom of the water collecting bucket 2, and the two side surfaces of the bottom of the water collecting bucket 2 are symmetrically provided with through grooves 13 for one end of the limit rod 12 to pass through, and the other end of the limit rod 12 is sleeved with a telescopic spring 14 on the outside, and a limit block 15 is installed at one end of the limit rod 12, and the two side surfaces of one end of the drain pipe 3 are symmetrically provided with limit grooves 16 for the limit block 15 to limit and engage, and the opening of the limit groove 16 extends to the end surface of the drain pipe 3, and the cross-section of the limit rod 12 is "T"-shaped, and the width of the top opening of the limit groove 16 is equal to the end surface diameter of the vertical part of the limit rod 12, which is convenient for workers to install and connect the drain pipe 3 with the water collecting bucket 2, and the operation is convenient and quick, and it is also convenient to improve the firmness of the installation of the drain pipe 3, and the practical effect is good.

[0023] The utility model provides a building drainage structure, and the specific working principle is as follows: when it rains, the water on the top of the building needs to be discharged through the drain port 1. At this time, the rainwater will fall into the interior of the drain port 1 through the through holes 7 on the surface of the protective cover 4. At the same time, the water on the top of the building can also flow to the interior of the drain port 1 through the limiting mesh ring 10 for discharge. When some impurities fall onto the surface of the protective cover 4, because the surface of the protective cover 4 is an arc surface, the impurities will not accumulate on the top surface of the protective cover 4. At the same time, when some heavier impurities fall onto the top surface of the protective cover 4, the protective cover 4 will rotate on the top of the support rod 6 through the rotating ball 8. At the same time, the connecting strip 11 at the inner edge of the protective cover 4 will deform until the heavier impurities roll off the surface of the protective cover 4. The protective cover 4 can rebound and reset through the connecting strip 11, so that the protective cover 4 and the limiting mesh ring 10 can achieve a better protection effect on the top of the opening of the drain port 1. The structure is simple, and it is also convenient for workers to assemble and install in the early stage, and the practicability is high. The utility model is installed and connected with the drain pipe 3 and the water collecting bucket 2 in the early stage. When the drain pipe 3 is drained, the drain pipe 3 is first pressed against the inner side of the bottom of the drain bucket 2, so that the opening of the limit slot 16 is aligned with the other end of the limit rod 12, and the expansion spring 14 between the one end of the limit rod 12 and the outer surface of the drain bucket 2 is squeezed to generate a rebound force. The limit rod 12 is aligned until one end of the drain pipe 3 is completely engaged with the bottom inner side of the water collecting bucket 2. Then the pressure on the limit rod 12 can be released. At this time, the rebound force generated by the telescopic spring 14 will act on the limit rod 12, so that the limit rod 12 drives the limit block 15 at the other end to be engaged with the inner bottom of the limit slot 16, so that the drain pipe 3 and the water collecting bucket 2 can be combined and installed, and the firmness of the connection between the drain pipe 3 and the water collecting bucket 2 is improved, so that the drain pipe 3 will not be easily separated from the water collecting bucket 2, and the practical effect is better.
