Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a buffer drainage device. Background Technology

[0002] Drainage pipes are the piping system used to organize drainage in roof drainage systems. Rainwater flows from the roof through the drainage pipes to the lawn outside the building. The ground and vegetation near the drainage outlets are exposed to rainwater erosion for extended periods, significantly reducing their survival rate and affecting their normal growth. This is especially true for substations and factories, where drainage pipe outlets are typically located within the lawn. The constant erosion near these outlets leads to areas of bare grass, severely impacting the overall aesthetic appeal. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a buffer-type drainage device that effectively buffers the water flow during drainage, reduces erosion near the drain outlet, and extends the service life of the drainage pipe. The technical solution adopted by this utility model is as follows:

[0004] A buffer-type drainage device includes a vertical drainage pipe and a horizontal drainage pipe, the vertical drainage pipe being connected to the horizontal drainage pipe, the horizontal drainage pipe being installed on the ground, and the end of the horizontal drainage pipe being a drain outlet. A horizontally placed first buffer plate is provided inside the vertical drainage pipe, and a vertically placed second buffer plate is provided inside the horizontal drainage pipe. The central part of the first buffer plate is an inner perforated plate with several through holes, and the outer ring part is a number of annularly distributed outer ring cavities. The central part of the second buffer plate is a number of annularly distributed inner ring cavities, and the outer ring part is an outer perforated plate with several through holes.

[0005] The aforementioned buffer drainage device also includes a ramp platform, which is located on the ground at the drain outlet of the horizontal drain pipe, and the inclination of the ramp platform gradually increases in the direction of gradually moving away from the drain outlet of the horizontal drain pipe.

[0006] In the aforementioned buffer-type drainage device, a retaining wall is installed on the inclined platform, the retaining wall is set corresponding to the drain outlet of the drainage pipe, and the retaining wall is provided with several through holes.

[0007] The aforementioned buffer drainage device has shaft heads on both sides of the retaining wall and support seats on both sides of the ramp. The shaft heads are rotatably installed in the support seats one by one. The ends of the shaft heads are provided with gear-shaped chucks, and the support seats are provided with retractable blocks to lock or release the chucks.

[0008] In the aforementioned buffer drainage device, an auxiliary support rod is hinged to the wall surface of the retaining wall, and a magnetic sheet is provided on the inclined platform. The lower end of the auxiliary support rod is magnetically attracted to the magnetic sheet.

[0009] The beneficial effects of this utility model are as follows: By setting buffer plates with different structures in different drainage pipes, the impact force can be reduced according to the characteristics of water flow, thereby achieving a buffering effect and greatly reducing the scouring of the ground and vegetation near the drainage outlet; it can also be equipped with sloping platforms and retaining walls to further improve the buffering effect. This device is suitable for drainage of substations and factories. Attached Figure Description

Detailed Implementation

[0015] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings. The following embodiments are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical terms used have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should be noted that the terminology used is for describing specific embodiments only and is not intended to limit the scope of this application.

[0016] This embodiment is a buffer-type drainage device, such as... Figure 1 As shown, it includes a vertical drain pipe 1 and a horizontal drain pipe 2, which are connected. The horizontal drain pipe 2 is installed on the ground, and its end is a drain outlet. A horizontally placed first buffer plate 3 is installed inside the vertical drain pipe 1, and a vertically placed second buffer plate 4 is installed inside the horizontal drain pipe 2. Both the first buffer plate 3 and the second buffer plate 4 are installed using conventional methods. Specifically, as shown... Figure 2 and Figure 3 As shown, the center of the first buffer plate 3 is an inner hole plate 31 with several through holes, and the outer ring is an outer ring cavity 32 with several fan-shaped cavities distributed in a ring. The center of the second buffer plate 4 is an inner ring cavity 41 with several fan-shaped cavities distributed in a ring, and the outer ring is an outer hole plate 42 with several through holes.

[0017] Most of the water in the vertical drain pipe 1 flows out through the outer ring cavity 32 and the water flow is relatively fast. The water flow in the inner orifice plate 31 is slower and the flow rate is small. Some of the water flowing out through the outer ring cavity 32 sticks to the inner wall of the vertical drain pipe 1, thereby increasing the resistance to the water flow and reducing the flow velocity. The water continues to flow through the second buffer plate 4. Since the through hole of the outer orifice plate 42 is small, the resistance to the water flow is increased again, so that most of the water flows out through the inner ring cavity 41, thereby achieving buffering of the water flow at the drain outlet.

[0018] In substations, factories, and other similar locations, the aforementioned buffer drainage device can preferably incorporate a ramp 5 and a retaining wall 6. Since the drainage pipes in substations and factories are typically surrounded by ground and vegetation, they do not obstruct normal passage. Therefore, the ramp 5 and retaining wall 6 can be installed in appropriate areas. The area of ​​the ramp 5 is significantly smaller than the scouring area at the outlet of the existing drainage pipe. The ramp 5 is positioned on the ground corresponding to the outlet of the horizontal drainage pipe 2, and its inclination gradually increases towards the outlet, thus buffering and guiding the water flow, allowing it to flow more smoothly towards the surrounding ground. The retaining wall 6 is installed on the ramp 5 and corresponds to the outlet of the drainage pipe 2. The retaining wall 6 has several through holes to reduce the impact of the water flow on its surface. The exterior of the retaining wall 6 can be used to display slogans, posters, etc.

[0019] Furthermore, such as Figure 1 and Figure 4 As shown, the retaining wall 6 has shaft heads 61 on both sides, and the ramp 5 has support seats 7 on both sides. The shaft heads 61 are rotatably installed in the support seats 7, so the tilt angle of the retaining wall 6 is adjustable. The end of the shaft head 61 is provided with a gear-shaped chuck 62, and the support seat 7 is provided with a retractable locking block 8. The locking block 8 can be locked between the teeth of the chuck 62. The tilt angle of the retaining wall 6 can be adjusted and fixed by the cooperation of the chuck 62 and the locking block 8. For example, when the drainage flow is large, the tilt angle between the retaining wall 6 and the ramp 5 can be slightly reduced to increase the blocking effect on the water flow.

[0020] An auxiliary support rod 63 is hinged to the inner wall surface of the retaining wall 6 for further support. A magnetic plate 51 is provided on the inclined platform 5. The lower end of the auxiliary support rod 63 is magnetically attracted to the magnetic plate 51, so as to facilitate the adjustment of the magnetic attraction position between the auxiliary support rod 63 and the magnetic plate 51 according to the inclination angle of the retaining wall 6.

[0021] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various changes or improvements without departing from the principles of this application, and these changes or improvements should also be considered within the scope of protection of this application.
