Description

Technical Field

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

[0002] Building rainwater drainage systems are an important part of building water supply and drainage systems. A common drainage method is to design a water collection tank and connect it to a drain pipe at the bottom. This method collects rainwater and discharges it in a centralized manner to prevent rainwater from accumulating and seeping on the roof.

[0003] Currently, drainage structures are designed with interceptor nets at the inlet to intercept debris such as leaves and garbage, preventing blockage of the drain outlet. However, long-term accumulation affects drainage efficiency. In addition, when not in use, the interceptor nets can also be blocked by debris, affecting drainage efficiency during rainfall. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing drainage structures intercept dirt and impurities through a net, but this affects drainage efficiency to some extent. In daily life, dirt and impurities can also easily clog the drainage structure and affect drainage.

[0005] To solve the above technical problems, the present invention provides the following technical solution: The present invention proposes a construction rainwater drainage structure, including a connecting pipe, a filter chamber connected to the top of the connecting pipe, a buffer chamber connected to the bottom of the connecting pipe, the filter chamber being funnel-shaped and having multiple sets of first drainage channels evenly distributed on the side wall with the central axis of the filter chamber as the center, and also includes a drainage component for adjusting the water flow.

[0006] The drainage assembly includes an outer pipe located at the bottom of the buffer chamber and communicating with the buffer chamber, and a slide rod slidably disposed within the filter chamber, connecting pipe, buffer chamber, and outer pipe. The inner side wall of the outer pipe is provided with a positioning rod, and the bottom of the slide rod is slidably disposed on the positioning rod. The top of the filter chamber is provided with a drain outlet. The top of the positioning rod is provided with a top plate that matches the drain outlet. The portion of the slide rod located inside the connecting pipe is provided with a sealing plate. A return spring is also sleeved on the slide rod, and the upper and lower ends of the return spring are respectively connected to the bottom wall of the sealing plate and the positioning rod.

[0007] Preferred technical solution 1: The top of the sealing plate is provided with multiple sets of guide rods, and the inner side wall of the connecting pipe is provided with a sliding groove that matches the guide rods.

[0008] Preferred technical solution 2: It also includes an installation plate located on the outer wall of the filter chamber, and the installation plate is provided with multiple sets of through holes.

[0009] Preferred technical solution 3: It also includes a protective ring, the mounting plate is provided with a positioning protrusion, the bottom of the protective ring is provided with a positioning groove, and the protective ring is provided with a second drainage groove.

[0010] Preferred technical solution four: The cross-sectional dimension of the connecting pipe is smaller than the cross-sectional dimension of the buffer chamber.

[0011] Preferred technical solution five: The top of the filter chamber is also provided with an auxiliary drainage trough.

[0012] The present invention proposes a rainwater drainage structure for building construction, and the beneficial effects achieved by using the above structure are as follows:

[0013] (1) The filter chamber and drainage components are designed to quickly discharge rainwater, while preventing large debris such as leaves and garbage from entering and causing blockages in normal conditions;

[0014] (2) The first and second drainage channels are set for drainage. If the drainage is not smooth, the auxiliary drainage channel at the top is used for drainage. During the drainage process, the water inlet is opened to speed up the drainage. Multiple anti-blocking measures are in place. The protective ring is set for easy daily cleaning and maintenance. There is no need to disassemble the structure for cleaning.

[0015] (3) The funnel-shaped filter chamber accelerates the drainage of rainwater. The high-speed flow can prevent particulate matter from settling and enable the inlet to be opened quickly. Then, the buffer chamber is connected to reduce the flow rate, reduce the scouring and wear on the pipe wall, and at the same time reduce pipe vibration and noise, and increase structural stability.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0024] Example 1

[0025] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a building construction rainwater drainage structure, including a connecting pipe 1, a filter chamber 2 connected to the top of the connecting pipe 1, a buffer chamber 3 connected to the bottom of the connecting pipe 1, the filter chamber 2 is funnel-shaped and the side wall is evenly distributed with multiple sets of first drainage channels 4 with the central axis of the filter chamber 2 as the center, and also includes a drainage component 5 for adjusting the water flow rate, for rapid drainage when the first drainage channel 4 is blocked;

[0026] The drainage assembly 5 includes an outer pipe 6 located at the bottom of the buffer chamber 3 and connected to the buffer chamber 3, and a slide rod 7 slidably disposed within the filter chamber 2, connecting pipe 1, buffer chamber 3, and outer pipe 6. The inner side wall of the outer pipe 6 is provided with a positioning rod 8, and the bottom of the slide rod 7 is slidably disposed on the positioning rod 8. The top of the filter chamber 2 is provided with a drain outlet 9. The top of the positioning rod 8 is provided with a top plate 10 that matches the drain outlet 9. The part of the slide rod 7 located inside the connecting pipe 1 is provided with a sealing plate 11. A return spring 12 is also sleeved on the slide rod 7, and the upper and lower ends of the return spring 12 are respectively connected to the bottom wall of the sealing plate 11 and the positioning rod 8. During the drainage process, the water pressure impact causes the sealing plate 11 to impact the buffer chamber 3. At this time, the slide rod 7 moves downward as a whole, so that the top plate 10 no longer seals the drain outlet 9, and the accumulated water can enter the structure quickly and in large quantities. At this time, the return spring 12 is compressed. Under normal conditions, the top plate 10 is sealed to the drain outlet 9 by the rebound force of the return spring 12, which prevents large debris such as leaves and garbage from entering and causing blockage in daily life.

[0027] like Figure 3 and Figure 4 As shown, the top of the sealing plate 11 is provided with multiple sets of guide rods 13, and the inner side wall of the connecting pipe 1 is provided with a sliding groove 14 that matches the guide rods 13, which is used to support and guide the sealing plate 11 in the sliding state. The top of the filter chamber 2 is also provided with an auxiliary drainage groove 19. When the first drainage groove 4 and the second drainage groove 18 are not draining smoothly, the water inlet is opened through the auxiliary drainage groove 19 at the top to achieve rapid drainage.

[0028] Preferred technical solution two:

[0029] Example 2

[0030] Based on Example 1, such as Figure 1 As shown, it also includes a mounting plate 15 located on the outer wall of the filter chamber 2, with multiple sets of through holes 16 evenly distributed on the mounting plate 15. In order to further reduce the clogging of the first drainage channel 4 by dirt and impurities, and to facilitate the cleaning of dirt in the water, a protective ring 17 is also included. The mounting plate 15 is provided with a positioning protrusion, and the bottom of the protective ring 17 is provided with a positioning groove for positioning. The protective ring 17 is provided with a second drainage channel 18 for intercepting impurities in the water and facilitating cleaning.

[0031] Furthermore, the cross-sectional dimensions of the connecting pipe 1 are smaller than those of the buffer chamber 3. This reduces the drainage flow rate, decreases frictional resistance, reduces scouring and wear on the pipe wall, and simultaneously reduces pipe vibration and noise, thereby increasing structural stability.

[0032] In practical use, the drainage structure is installed on the ground at the drainage position via the mounting plate 15. The filter chamber 2 is higher than the ground. Under normal conditions, the return spring 12 acts to seal the top plate 10 against the drain outlet 9, preventing large debris such as leaves and garbage from entering and causing blockage. The protective ring 17 forms the first line of protection, intercepting impurities in the water and facilitating cleaning. Rainwater enters the filter chamber 2 through the second drainage channel 18 and the first drainage channel 4. If both are blocked, drainage can also be achieved through the auxiliary drainage channel 19. The water entering the filter chamber 2 enters the connecting pipe 1. The water pressure impact causes the sealing plate 11 to impact the buffer chamber 3. At this time, the sliding rod 7 moves downward as a whole, so that the top plate 10 no longer seals the drain outlet 9. The accumulated water can quickly enter the interior of the structure and be quickly drained away.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, material, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, material, or apparatus.

[0034] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.
