[0059] With the exhaust vertical pipe 1 as the vertex, the first drainage vertical pipe 2 and the first connecting pipe 41 form a first projection in the horizontal plane, and the second drainage vertical pipe 3 and the second connecting pipe 42 form a second projection in the horizontal plane, and the angle between the second projection and the first projection is 30 degrees to 90 degrees; the first drainage vertical pipe 2 and the second drainage vertical pipe 3 are both provided with inspection ports 5.

[0060] Preferably, the double H-shaped drain pipe of this embodiment is convenient for maintenance, such as Figure 1-2 As shown, the first connecting pipe 41 and the second connecting pipe 42 are arranged at a certain angle to the horizontal plane; the angle between the second projection and the first projection is 60 degrees.

[0061] Preferably, the double H-shaped drain pipe of this embodiment is convenient for maintenance, such as Figure 1-2 As shown, the inspection opening 5 on the first drainage vertical pipe 2 faces the second drainage vertical pipe 3, and the inspection opening 5 on the second drainage vertical pipe 3 faces the first drainage vertical pipe 2. This arrangement can further reduce the space occupied by the inspection opening 5.

[0062] Preferably, the double H-shaped drain pipe of this embodiment is convenient for maintenance, such as Figure 1 As shown, the connection port of the first connecting pipe 41 with the exhaust vertical pipe 1 is higher than the connection port with the first drainage vertical pipe 2; the connection port of the second connecting pipe 42 with the exhaust vertical pipe 1 is higher than the connection port with the second drainage vertical pipe 3. This structure is conducive to exhaust.

[0063] Preferably, the double H-shaped drain pipe of this embodiment is convenient for maintenance, such as Figure 3 As shown, the inspection port 5 includes:

[0064] An inspection port base 51 is integrally connected to the side wall of the first vertical drainage pipe 2 or the second vertical drainage pipe 3, and the inspection port base 51 is provided with an opening connected to the interior of the first vertical drainage pipe 2 or the second vertical drainage pipe 3;

[0065] The cover plate 52 covers the inspection port base 51 to close the opening. The cover plate 52 is detachably mounted on the inspection port base 51 via a fixing member.

[0066] Preferably, the double H-shaped drain pipe of this embodiment is convenient for maintenance, such as Figure 3 As shown, the edges of the cover plate 52 and the inspection port base 51 are both provided with positions for inserting bolts, and the fixing members are bolts.

[0067] Example 2

[0068] This embodiment provides a double H-shaped drain pipe that is easy to repair. Figure 4-6 As shown, the difference from the embodiment 1 is the specific structure of the inspection port 5: the cover plate 52 is provided with through holes centered on the four vertices of the rectangle, and a locking assembly 6 is installed at the through hole, and the locking assembly 6 includes: a rotating shaft 61 installed in the through hole, a knob 62 is fixed at one end of the rotating shaft 61, and a clamping block 63 is fixed at the other end;

[0069] The front surface of the inspection port base 51 is provided with two vertical T-slots 512, and the two T-slots 512 are respectively arranged corresponding to the locking components 6 on both sides of the cover plate 52, so that the clamping block 63 can be inserted into the T-slots 512;

[0070] The two sides of the T-shaped groove 512 are also provided with a slope structure 513, and the cross-sectional shape of the slope structure 513 in the horizontal plane is a slope shape;

[0071] The clamping block 63 can be inserted into the T-slot 512 when it is vertical, and can be clamped on the slope structure 513 when it is horizontal, so that the locking assembly 6 can fix the cover plate 52 on the inspection port base 51.

[0072] like Figure 1 As shown, since the double H-shaped drain pipe for easy maintenance in this embodiment has a compact structure, the operating space of the fixing parts of the cover plate 52 is small, which is actually not conducive to the use of tools such as wrenches. Therefore, in this embodiment, the fixing parts use a special locking assembly 6. When installing the cover plate 52, all knobs 62 are turned to make the block 63 vertically, and then the block 63 is inserted from top to bottom along the corresponding T-slot 512. When the cover plate 52 and the inspection port base 51 are aligned, all knobs 62 are turned to make the block 63 horizontally, as shown in FIG. Figure 6As shown, when the block 63 is in the horizontal direction, both sides of the block 63 abut against the slope structure 513. When the block 63 is transformed from the vertical direction to the horizontal direction, the block 63 is gradually clamped along the slope of the slope structure 513, that is, the cover plate 52 is gradually pressed against the inspection port base 51, so as to achieve a tightening effect and avoid leakage.

[0073] Preferably, the double H-shaped drain pipe of this embodiment is convenient for maintenance, such as Figure 5 As shown, the lower end of the T-slot 512 is closed. This structure can facilitate the installation of the cover plate 52.

[0074] Preferably, the double H-shaped drain pipe of this embodiment is convenient for maintenance, such as Figure 5 As shown, the shape of the block 63 is a rounded rectangle.

[0075] Preferably, in the double H-shaped drain pipe of this embodiment for easy maintenance, a sealing gasket is provided on the inner side of the cover plate 52 to enhance the sealing performance.

[0076] Example 3

[0077] This embodiment provides a double H-shaped drain pipe that is easy to repair. Figure 7 As shown, the difference from Example 1 is that the two ends of the exhaust vertical pipe 1, the first drainage vertical pipe 2 or the second drainage vertical pipe 3 have flange connection parts. This structure can facilitate the connection of the double H-shaped drainage pipe to the upper and lower drainage systems.

[0078] In this embodiment, the inspection port 5 faces the side away from the exhaust vertical pipe member 1. Preferably, it faces the plane perpendicular to the first drainage vertical pipe member 2 and the second drainage vertical pipe member 3.

[0079] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
