V. INSTRUCTIONS (1) 1. Technical Field of the Invention The present invention relates to a flood control method for a metropolitan area and a design of a water head, which is installed on a house by using a water head, and automatically adjusts the drain hole. Controlling the rainwater falling on the roof can automatically adjust the displacement with the addition of the road platform to make it smaller. You can fight for drainage. ^: The amount of rain on the ground after the rainfall can avoid the loss of the metropolitan area/space priority. The disadvantage of flooding due to the large amount of rainfall. ^ Due to the encounter two, [previous technology] According to the various buildings in the metropolis, the green space is reduced, and the ground floor is paved with no thick, one natural and thus the land surface. Therefore, it is effective in the city. The drainage and rainwater>The drainage floor and the rainwater channel are built on the ground floor under the surface of the concrete surface. The drainage channel is used to make the rainwater on the road surface, and then the rainwater channel is widely distributed. And discharged downstream into the sea. The rainwater is collected into the drainage ditch on both sides of the road. The discharge capacity b and the quantity limit are limited depending on the width and depth of the gutter. However, if the limit is large, when the flow is heavy, the area with a lower elevation is It may be that the water is not enough to cause the accumulation of water, which has evolved into a flood. ~ The thin diversion speed is in the middle of the city. The building has a very large number of buildings. The total surface area of the top floor terrace is relatively large, so that the top layer of each building layer can withstand the rain after falling. = two tops, the drainage hole on the platform and the rainwater is discharged downwards, so by the time of heavy rain, the water outlet speed at the drainage hole of the roof of the roof can be controlled, so that the rainwater is slightly stuck in the high place, on the ground. The drainage ditch will give priority to the plum road

Invention description (2), , ^ K 'can avoid the occurrence of floods on roads and roadways; and when the amount of rain is slowing down, the water on each top floor can slowly accelerate the downward discharge speed at this time on the ground. The drainage ditch also has ample space to quickly discharge the rainwater from the top floor. 'This method and related automatic control of the water output drop head setting °' will effectively prevent the occurrence of water in the area of the metropolitan area, resulting in waterproofing. damage. "The known structure of the falling head is the case of the improved falling head structure of the Republic of China Patent No. 8 8 2 0 2 8 3 0. The patent of the case is characterized by the provision of a multi-layer telescopic cylinder, a cover plate and a water board. The multi-layer telescopic cylinder comprises a series combination of a bottom cylinder 'an intermediate cylinder and a top cylinder, each of the circumferential surfaces of the cylinders has an upwardly inclined cone shape, and the top end of the top cylinder is sleeved on the inner wall of the perforated inner wall of the cover plate. On the edge of the edge. The purpose of the design of the case is that the floor surface may be heightened due to the decoration. Therefore, in order to match the height of the end of the drain pipe, a length-adjustable drainage head structure design can solve the difference in the height of the floor surface. problem. However, how to prevent the urban area from being flooded easily on the heavy rain surface can not be effectively solved by increasing the capacity of the drainage ditch, because when the climate changes, when will it drop as much as several hundred millimeters of rainfall. It is not known that in the case of heavy rain, the rainfall is more than 100 mm per hour. Most of the drainage ditches in the city cannot load such a large amount of rainfall as a guide. In view of this, the inventor designed a drainage drop head structure that is simple in construction and easy to manufacture, and can automatically generate a regulated displacement when it encounters heavy rain, so as to slow down the rainwater of the roof of the house to the ground at the first time, so

Page 8 1255306 V. INSTRUCTIONS (5) The discharge of water head (60) (Fig. 4, 5) can gradually accumulate water on the top floor terrace. The top end of the base (10) is provided with a notch (14)' and a shutter (15) extends upward from the inner side of the notch, and a large frame (丨6) is provided in the center of the base (1). The top end of the seat (20) protrudes from the inside to the outside through the large frame opening (16). As shown in Fig. 1, the intermediate seat (20) has a shape similar to that of the base (丨〇), and also has a horizontal plate (21) laterally expanded at the bottom end and a notch (22) at the top end, at the bottom edge of the vertical wall. There are several drainage ports (23) in the hollow, and a large frame (24) in the center of the middle seat (2) can provide a top seat (3〇) and protrude from the inside to the outside through the large frame (24). Out. As shown in Fig. 1, the top seat (30) has a horizontal plate (31) laterally extending at the bottom end, a notch (32) at the top end, and a screw hole (3 3) at the center of the top end. 30) After the large frame (24) at the center of the middle seat (2〇) is pierced, it is connected to a pontoon (4 〇) by a screw (5 1 ). The structure of the pontoon (40) described in the second embodiment is a combination of a cover (41) and a tray (42), and is preferably composed of a cover (4 丨) on the side edge of the circumference. The convex ring (43) is provided with a groove (44) on the inner side wall of the tray (42), and the protruding ring (10) and the groove (10) are mutually fixed and sealed. When the invention is capable of automatically adjusting the amount of water, the head of the water can be placed on the floor of the original top floor by means of a nail (5〇) which is nailed to the ground along the base (1〇)=nail hole (1 2). Luoshui = (60) (as shown in Figure 4) is covered directly. As shown in Fig. 4, the present invention is fixed to the drainage hole by nails (50), and when it is raining, for a small amount of rainfall, the amount of water can be reduced by the base (10).

The passages (13) and (23) formed by the drain port (23) of the invention (6) | The water capacity of the $, first | head (60). ^ ^ Please refer to Figure 5. Chuan Baili discharges rainwater. At this time, the discharge capacity of each row is smaller than the original falling water Meng·food group j four " 丨 small, when encountering the Japanese mouth (1 3), (23) through the flow channel: when the mountain to rain more, As a result of the above-mentioned drainage, the total amount of water dropped by the dingbei rainwater is therefore unable to withstand the state of the water with a large rain. At this time, it is necessary to know that the floor of the terrace on the tower has begun to form a product. I Building T 笞 笞 笞 丨 丨 . . . | | 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速 快速At this time, when the drainage potential is large, the low-lying land is rained on the ground, when the rain occurs. However, the pavement of the present invention has a state of standing water accumulated in a local road section, so that the shoulder structure is continuously maintained, and the water discharge capacity of the terrace floor shape (23) of the top floor is arranged in an appropriate amount, and is provided by each drain port ( 13), quickly descending on the ground to drain,; 'avoid a large amount of rainwater ditch on the top floor terrace' to prevent the accumulation of water on the road surface more serious, as in Figure 3, the real life of the Shanghai M' its rainfall Apparently it is larger than the falling water head Ι7 ί k # 2 The roof of the rainwater level on the top floor of the tower is gradually rising. When the water level rises to the south to reach the position of the pontoon (4 〇), the pontoon (4 〇) will naturally drive the top. The seat (30) is raised upwards, so that the gap (2 2 ) at the top end of the intermediate seat (20) is blocked by the horizontal plate (31) on the top seat (3〇) to reduce the amount of water falling to the ground and prevent The water accumulated on the road surface of the building occurred. On the other hand, under the water level of a certain degree, the gap (顶端4) at the top of the base (1 〇) is still open to drain water to avoid the excessive accumulation of water on the top floor terrace. However, as shown in Figure 6, when the amount of rain increases and lasts, the head is discharged.

Page 10 1255306 V. INSTRUCTIONS (7) When the water volume is even more unloadable, the pontoon (4 〇) is raised and then the top seat (30) is also raised and the top of the top seat (30) is horizontal. The plate (3丨) thus blocks the notch (22) at the top end of the intermediate seat (20), and the horizontal plate (21) at the bottom end of the intermediate seat (20) also blocks the notch (14) at the top end of the base (10), and The drain port (23) on the vertical wall at the bottom of the middle seat (2〇) will be covered by the shutter (1 5) on the base (1 于) when it is raised to the end of the stroke, so it is only retained. The water outlet (1 3 ) at the bottom of the base (丨〇) and the notch (3 2) at the top of the top seat (30) can be a small amount of water, because when such a large amount of rain falls, the roads are everywhere. The water has been accumulated, so the design concept of the present invention is to leave part of the rainwater on the terraces of each floor. 'After the water on the bottom of the building has subsided, the rainwater on the top floor terrace is quickly discharged to the ground'. The sequential drainage method is effective to avoid the problem of flooding when the road surface in the city is hit by heavy rain. In addition, as shown in Figures 4 to 6, similarly, the water head of the present invention is located at the bottom end of the base (1 〇) at the bottom of the base (1 3 ) and the top seat (3) after the rain has gradually subsided. 0) The gap at the top (3 2) to remove the accumulated water. When the water level drops, the pontoon (40) is lowered to the height of the intermediate seat (20), indicating that the rainfall is less than the displacement. Therefore, the horizontal plate (31) is due to the pontoon. (40) The height is lowered to form an open shape, and the accumulated water can be discharged along the top end (22) of the intermediate seat (20) to speed up the discharge. When the water level drops further (40), it will even open the gap (14) at the top end of the base (1〇), so that the water on the top floor terrace is completely drained. Referring to Figures 7 and 8, in another preferred embodiment of the present invention, the intermediate seat (20 a) at the intermediate twist is also provided with a pontoon structure thereon, so that it can also have its own automatic The floating function, in this embodiment, is changed by providing a sandwich space (25) on the outer side of the intermediate seat (20 a) in the interlayer

1255306

The bottom end of the space is designed as a closed end, and the blade can be sealed at the top of the sandwich space. It can also be designed as the open end of the figure. The upper end of the pontoon (4 〇) has a width larger than the middle seat (2 〇 a). Therefore, even if the heavy rain does not enter the water in the mezzanine space (25), the mezzanine space (25) is set so that the intermediate seat (20 a) itself has a certain buoyancy when it encounters the water accumulation state. Therefore, as shown in Figure 8, when the water level rises to a certain height, the middle seat (2 〇 a ) can rise, and it does not need to rely on the top seat (3 〇) to rise to the end of the stroke to have the effect of lifting. When the water level is submerged over the height of the top seat (3 〇), the mezzanine space (25) provided by the middle seat (20 a) is also flooded with rainwater. When the water level subsides, the embodiment can be accelerated. The function of lowering the height of the pontoon (40) is therefore also that the water outlet notch (32) on the top seat (3 )) and the water outlet notch (2 2) on the middle seat (20 a) can be opened more quickly. It is conducive to the speed of water removal. In this embodiment, it should be noted that the buoyancy of the pontoon (40) should be greater than the weight of the interlayer (25) when it is full of water, so that the intermediate seat (20a) can be lifted when the accumulated water level is higher than the pontoon (4 〇). ). Therefore, as shown in FIG. 9, in the configuration of another embodiment of the present invention, the float (40) may be provided with a button hole (45), and the top end of the top seat (30) is provided with a buckle. (34) 'Buckling 榫 and buttonholes can be directly embedded. However, the vertical walls of the base (1 〇), the intermediate seats (20), (20a) and the top seat (30) shown in the embodiments of the present invention are smoothly demolded during the manufacture of the plastic injection molding, so that The vertical wall is slightly sloped so that it can provide a smoother sliding effect for the intermediate seats (20), (20a) and the top seat (30) during the ascent.
