Detailed Description
The present invention is further illustrated by the following examples, which should not be construed as limiting the scope of the invention.
Example (b): compare FIGS. 1-5
A pre-buried floor drain of a vertical pipe of a rainwater drainage system comprises a protective cover 3, a water collecting tray 4, an upper vertical pipe 1, a lower vertical pipe 2 and a main body 5 used for connecting the upper vertical pipe 1 and the lower vertical pipe 2, wherein the main body 5 comprises a large circular pipe 51, a reducing pipe and a small circular pipe 52 which are arranged from top to bottom, and a retraction structure matched with the inner space of the main body 5 is processed at the lower end of the upper vertical pipe 1, so that the lower end of the upper vertical pipe 1 is matched and inserted in the main body 5.
A plurality of vertical grid plates 5b are uniformly arranged on the outer side of the small circular tube 52 at intervals along the circumferential direction, and when the small circular tube 52 is inserted in the lower vertical tube 2 in a matching manner, all the grid plates 5b on the outer side of the small circular tube 52 are in close contact with the inner wall of the lower vertical tube 2. The bottom surface of the grid plate 5b is disposed flush with or close to the bottom port of the small circular tube 52.
The water collecting tray 4 is arranged on the outer side of the main body 5, the protective cover 3 is arranged on the outer side of the water collecting tray 4, accumulated water enters the water collecting tray 4 after being filtered by the protective cover 3 and then flows into the lower vertical pipe 2 through a water flow channel formed among the outer wall of the small circular pipe 52, the grid plate 5b and the inner wall of the lower vertical pipe 2 to be discharged. In the comparison of fig. 1, a plurality of strip-shaped grating holes are uniformly arranged around the side part of the protective cover 3 at intervals so as to amplify particles and impurities entering the water collecting tray 4 along with water flow.
In comparison with fig. 2 and 3, the water collecting tray 4 includes an annular backing plate, an annular positioning plate 42 and a disc main body 41 with a slope inclined surface arranged between the annular backing plate and the annular positioning plate 42, the annular positioning plate 42 is horizontally and fixedly arranged on the peripheral edge of the disc main body 41, the annular backing plate is horizontally and fixedly arranged at the central position of the disc main body 41, and the central through hole of the annular backing plate can be sleeved on the outer side of the main body 5; the bottom surface of the disc main body 41 is provided with a plurality of reinforcing ribs 43 at even intervals along the circumferential direction.
The disc body 41 has a slope to facilitate the downward collection of water entering the disc body 41. Further, the slope of the slope surface of the disc body 41 is 10 to 15 °.
In order to facilitate the water collecting tray 4 to be sleeved outside the main body 5, the following manner can be adopted: a plurality of baffles 5a are uniformly arranged at intervals along the circumferential direction outside the reducer, and the bottom surfaces of the baffles 5a are horizontal planes; the upper ends of the grid plates 5b are fixedly arranged on the outer wall of the convergent pipe, and the upper end of each grid plate 5b is arranged between two adjacent baffle plates 5a, so that the baffle plates 5a on the main body 5 and the grid plates 5b are arranged at intervals in the vertical direction.
The lower vertical pipe 2 is tightly inserted at the outer sides of all grid plates 5b on the small round pipe 52, meanwhile, the annular base plate of the water collecting disc 4 is tightly sleeved at the outer sides of all grid plates 5b on the small round pipe 52 through the central through hole of the annular base plate, and the annular base plate of the water collecting disc 4 is tightly clamped between the top port of the lower vertical pipe 2 and the bottom surface of the baffle 5a, so that the water collecting disc 4 is fixedly installed at the outer side of the main body 5; wherein a water flow channel is formed among the water collecting tray 4, the upper end of the grid plate 5b, the baffle 5a and the outer wall of the convergent pipe. It can be seen that the outer wall surface of the reducer and the outer wall surface of the small circular tube 52 are not in direct contact with the annular pad of the water collection tray 4, and the water collected on the water collection tray 4 can directly flow into the lower stand pipe 2 from the outer side of the main body 5 for discharge after passing through the annular pad.
In order to make the water collecting tray 4 more firmly fit on the outside of the main body 5, the following way can be followed: the bottom of the annular backing plate of the water collecting tray 4 is also provided with a short limiting pipe, the top port of the lower vertical pipe 2 tightly props the annular backing plate of the water collecting tray 4 against the bottom surface of the baffle 5a, and meanwhile, the pipe wall of the upper end of the lower vertical pipe 2 is also tightly inserted into an annular space between the short limiting pipe of the water collecting tray 4 and all grid plates 5b on the small circular pipe 52.
The rainwater drainage system is simple in structure and is used in the rainwater drainage system. When the balcony structure board is constructed, the water collecting disc is embedded and installed firstly, the bottom surface of the disc main body is embedded in the balcony structure board, the reinforcing ribs of the disc main body are used for stabilizing the water collecting disc so as to prevent looseness, and the annular positioning pieces on the peripheral edge of the water collecting disc are flush with the surface of the balcony structure board. The main body is firstly installed on the water collecting tray, and then the upper vertical pipe and the lower vertical pipe are connected with the main body. The strip-shaped grating holes of the protective cover can prevent large granular sundries from entering to cause floor drain blockage. The safety cover can upwards slide along the upper vertical pipe, so that the floor drain is convenient to clean. When water is accumulated on the ground of the balcony, the accumulated water flows into the water collecting tray firstly and then flows into the lower vertical pipe through the grid plate on the outer side of the main body. The inclined plane of the disc main body of the water collecting disc has a certain inclination, so that accumulated water can conveniently flow into the floor drain.
The statements in this specification merely set forth a list of implementations of the inventive concept and the scope of the present invention should not be construed as limited to the particular forms set forth in the examples.
