In rainy days, rainwater falls into the water tank 66, the mass of the water tank 66 is increased along with the increase of the rainwater level, when the sum of the mass of the water tank 66 and the mass of the rainwater is greater than the elastic force provided by the spring 67, the water tank 66 pushes the worm 64 downwards, in the process, the spring 67 is stressed and contracted, the worm 64 drives the worm wheel 65 meshed with the worm to rotate, meanwhile, the worm wheel 65 drives the threaded rod 3 fixed with the worm wheel to rotate, and the circumferential rotation of the movable plate 5 is limited by the guide rod 4, so that the movable plate 5 moves towards one side of the side wall of the parapet 2 along the threaded rod 3, the inserting rod 51 moves towards one side of the drain hole 21 and the drain hole 21 is dredged, and the possibility that the drainage performance of a roof structure is influenced due.

As shown in fig. 3, the diameter of the limiting plate 63 is greater than that of the through hole 621, so that the limiting plate 63 is well limited, the situation that the limiting plate 63 goes out of the through hole 621 due to overlarge elastic force of the spring 67 is avoided, and smooth dredging of the drain hole 21 is facilitated.

As shown in fig. 1, a water seepage hole 661 is formed through the bottom of the water tank 66, the cross section of the water seepage hole 661 is circular, the axis of the water seepage hole 661 is vertical, and a plug 662 is installed in the water seepage hole 661. The plug body 662 is made of rubber material, and the side wall of the plug body 662 is tightly abutted against the side wall of the water seepage hole 661, so that the water tank 66 can normally store water. After the drain hole 21 is dredged, the worker only needs to take the plug body 662 out of the seepage hole 661, so that the accumulated water in the water tank 66 can be drained out, and finally the accumulated water is drained out of the roof through the drain hole 21.

As shown in fig. 1, the upper surface of the cement layer 14 is further provided with a limiting rod 7 and a fixing ring 8, the limiting rod 7 is of a round rod-shaped structure, the axis of the limiting rod 7 is vertical, and the upper end and the lower end of the limiting rod 7 are respectively fixed with the bottom surface of the water tank 66 and the upper surface of the cement layer 14. The height that highly is greater than worm wheel 65 top arc surface of gag lever post 7 upper end, and gag lever post 7 has played good limiting displacement to basin 66, has avoided taking place because of the condition that the quality of basin 66 water-logging is too big and leads to the touching worm wheel 65 top in the bottom of basin 66, has guaranteed going on smoothly of mediation work. The fixing ring 8 is of a circular ring-shaped structure, the axis of the fixing ring coincides with the axis of the cylindrical shell 62, the fixing ring 8 is sleeved outside the worm 64, and the lower end face of the fixing ring 8 is fixed to the upper end face of the cylindrical shell 62, so that the phenomenon that rainwater on the upper surface of the cement layer 14 enters the cylindrical shell 62 from the through hole 621 is avoided.

The implementation principle of the embodiment is as follows: when sundries enter the drain hole 21 and the drain hole 21 is blocked, a worker only needs to drive the threaded rod 3 to rotate through the driving assembly 6, at the moment, the circumferential rotation of the movable plate 5 is limited by the guide rod 4, so that the movable plate 5 moves towards one side of the side wall of the parapet wall 2 along with the rotation of the threaded rod 3 until the inserted rod 51 on the movable plate 5 is inserted into the drain hole 21, the drain hole 21 is dredged, and the situation that the drainage work of a roof structure is affected due to the blockage of the drain hole 21 is avoided.

In the roof structure in the scheme, when the rainwater falls into the water tank 66 in rainy days, the mass of the water tank 66 is increased along with the rise of the water level of the rainwater in the water tank 66, when the sum of the mass of the water tank 66 and the mass of the rainwater is larger than the elastic force provided by the spring 67, the spring 67 is gradually in a compressed state, the water tank 66 pushes the limiting plate 63 through the worm 64, so that the limiting plate 63 moves downwards along the cylindrical shell 62, meanwhile, the worm 64 drives the worm wheel 65 meshed with the worm wheel to rotate, the worm wheel 65 drives the threaded rod 3 fixed with the worm wheel 65 to rotate, and the circumferential rotation of the movable plate 5 is limited by the guide rod 4, so that the movable plate 5 moves towards one side of the side wall of the parapet 2 until the inserted rod 51 is inserted. In order to avoid the influence on the drainage performance of the roof structure caused by the fact that the inserted rod 51 is always positioned in the drainage hole 21, a worker only needs to take out the plug body 662 in the seepage hole 661, so that rainwater in the water tank 66 can be drained, under the elastic action of the spring 67, the water tank 66 can move upwards, the worm 64 moves upwards along with the water tank 66 synchronously, the worm 64 drives the worm wheel 65 meshed with the worm 64 to rotate, the movable plate 5 moves towards one side far away from the parapet 2, the inserted rod 51 is separated from the drainage hole 21, and the roof structure can keep normal drainage performance.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
