Description

Technical Field

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

[0002] The design of the roof drainage system is crucial during the construction of a house. Traditional roof drainage structures have many problems, such as poor drainage, which can easily lead to water accumulation on the roof, affecting the normal use of the house and the surrounding environment.

[0003] Existing drainage structures are ineffective at intercepting debris. Leaves, garbage, and other debris can easily enter the drainage pipes with the water flow, causing blockages. This not only increases maintenance costs but may also lead to drainage system malfunctions, affecting residents' quality of life. Moreover, blockages usually require manual cleaning, which is inefficient. Therefore, there is an urgent need to design a new drainage structure for housing construction to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage structure for building construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drainage structure for a building includes a drainage hopper installed in a wall. A drainage pipe is fixedly installed at the bottom of the drainage hopper, and a filter screen is fixedly installed on the inner wall of the drainage hopper near the top. A cleaning component is provided in the middle of the filter screen and on the inner wall of the drainage hopper. A return pipe is fixed to one side of the drainage pipe, and a debris collection box is fixedly installed at the top of the return pipe and at the bottom of the wall. A connection hole is provided at the top of the debris collection box. A debris discharge trough is provided in the wall and at the top of one side of the drainage hopper, and the bottom of the debris discharge trough communicates with the connection hole.

[0007] Furthermore, the cleaning component includes an installation hole in the middle of the filter screen, and an installation cylinder is fixedly installed on the inner wall of the installation hole. An internal threaded cylinder is rotatably connected to the inner wall of the installation cylinder through a sealed bearing. A threaded rod is screwed onto the inner wall of the internal threaded cylinder. A lifting component is provided at the bottom of the threaded rod and the inner wall of the drain hopper. Arc-shaped scrapers are fixedly installed at both ends of the top of the internal threaded cylinder, and the arc-shaped scrapers are attached to the top of the filter screen.

[0008] Furthermore, the lifting assembly includes a water-holding cylinder fixedly installed at the bottom of the threaded rod, with the water-holding cylinder located at the center of the drainage hopper. The bottom of the water-holding cylinder has equally spaced drainage holes. The inner wall of the drainage hopper is fixedly fitted with equally spaced guide frames, which are designed to be inclined. The bottom of the guide frames is located above the water-holding cylinder. The outer wall of the mounting cylinder and the inner wall of the drainage hopper are fixedly fitted with equally spaced reinforcing rods, and the bottom of each reinforcing rod is fixed with a guide rod passing through the drainage holes. The positions of the guide rods and the guide frames are staggered. The bottom of each guide rod is fixedly fitted with a sealing sleeve that fits against the inner wall of the drainage hole, and the bottom end of the sealing sleeve is designed to be conical. The top of the inner wall of the water-holding cylinder is fixedly fitted with guide plates equally spaced around the guide rods. The outer wall of the guide rods near the bottom is fixed with fixing rings, and the top of the fixing rings and the bottom of the guide plates are fixedly fitted with springs that fit around the outer wall of the guide rods.

[0009] Furthermore, a reinforcing base is fixedly installed on the inner wall of the drainage hopper and the bottom of the guide frame, and a reinforcing plate is fixedly installed on one side of the guide frame and one side of the guide rod.

[0010] Furthermore, a water collection trough is provided at the top of the drainage hopper and the top of the wall, and an annular guide plate is fixedly installed on the top of the inner wall of the drainage hopper. The cross-sections of the annular guide plate and the water collection trough are both designed to be inclined.

[0011] Furthermore, the upper part of the waste removal trough is designed to be inclined, and one end of the bottom inner wall of the upper part of the waste removal trough is flush with the top surface of the filter screen.

[0012] Furthermore, an inclined filter screen is fixedly installed at the bottom corner of the impurity collection box, and the impurity collection box is detachably connected to the wall and the return pipe by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a filter screen accurately intercepts leaves, garbage, and other debris, preventing them from entering the drain pipe and causing blockages. Simultaneously, a water-driven cleaning component achieves self-cleaning. During rainfall, water flows through an inclined guide frame and converges into a water-collecting cylinder. The increased weight of the cylinder overcomes the spring force and descends, causing a threaded rod to move downwards. This, in turn, drives the inner threaded cylinder to rotate, ultimately causing an arc-shaped scraper to rotate along the top surface of the filter screen, pushing the intercepted debris into the discharge trough. The entire process requires no manual intervention, forming a closed loop from source interception to automatic cleaning. This solves the problem of pipe blockage caused by debris in traditional drainage structures, reducing maintenance frequency and costs.

[0015] In this invention, the intercepted debris flows into the impurity collection box through the discharge trough, thus realizing the function of collecting impurities. The collection box is detachably connected to the wall and the return pipe by screws. When cleaning, only the impurity collection box needs to be removed to centrally process the debris, without having to climb the roof or dismantle the pipes. At the same time, the inclined filter screen at the bottom of the collection box filters out the moisture carried in the debris, allowing it to enter the drain pipe along the return pipe and be discharged, thus preventing some moisture from accumulating in the impurity collection box and affecting the collection function.

[0016] In this invention, the annular guide plate at the top of the drainage hopper works in conjunction with the inclined water collection trough at the top of the wall to quickly collect rainwater from the roof into the drainage hopper, thus preventing water accumulation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6In this embodiment of the utility model, a drainage structure for building construction includes a drainage hopper 5 installed in a wall 1. A drainage pipe 4 is fixedly installed at the bottom of the drainage hopper 5, and a filter screen 8 is fixedly installed on the inner wall of the drainage hopper 5 near the top. A cleaning component 9 is provided at the middle of the filter screen 8 and the inner wall of the drainage hopper 5. The cleaning component 9 includes an installation hole 911 at the middle of the filter screen 8, and an installation cylinder 91 is fixedly installed on the inner wall of the installation hole 911. An internally threaded cylinder 92 is rotatably connected to the inner wall of the installation cylinder 91 through a sealed bearing. A threaded rod 98 is screwed onto the inner wall of the internally threaded cylinder 92. A lifting component is provided at the bottom of the threaded rod 98 and the inner wall of the drainage hopper 5. Arc-shaped scrapers 93 are fixedly installed at both ends of the top of the internally threaded cylinder 92, and the arc-shaped scrapers 93 are attached to the inner wall of the drainage hopper 5. At the top of the filter screen 8, the lifting assembly includes a water-holding cylinder 96 fixedly installed at the bottom of the threaded rod 98, and the water-holding cylinder 96 is located at the center of the drain hopper 5. The bottom of the water-holding cylinder 96 has equally spaced drainage holes 915. The inner wall of the drain hopper 5 is fixedly installed with equally spaced guide frames 94, which are designed to be inclined. The bottom of the guide frames 94 is located above the water-holding cylinder 96. The outer wall of the mounting cylinder 91 and the inner wall of the drain hopper 5 are fixedly fitted with equally spaced reinforcing rods 910, and the bottom of each reinforcing rod 910 is fixed with a guide rod 99 passing through the drainage holes 915. The positions of the guide rods 99 and the guide frames 94 are staggered. The bottom of each guide rod 99 is fixedly fitted with a sealing sleeve 97 that fits against the inner wall of the drainage hole 915. The bottom of 7 is designed as a cone. The top of the inner wall of the water tank 96 is fixed with guide plates 913 that are equidistantly sleeved on the guide rod 99. The outer wall of the guide rod 99 near the bottom is fixed with fixing rings 916. The top of the fixing rings 916 and the bottom of the guide plates 913 are fixed with springs 914 that are sleeved on the outer wall of the guide rod 99. A return pipe 3 is fixed on one side of the drain pipe 4. The top of the return pipe 3 and the bottom of the wall 1 are fixed with a sludge collection box 2. The top of the sludge collection box 2 is provided with a connection hole 11. The top of the wall 1 and the side of the drain hopper 5 is provided with a sludge discharge trough 10. The bottom of the sludge discharge trough 10 is connected to the connection hole 11. The upper part of the sludge discharge trough 10 is designed as an incline. One end of the bottom inner wall of the upper part of the sludge discharge trough 10 is connected to the top surface of the filter screen 8. A slanted filter screen 12 is fixedly installed at the bottom corner of the impurity collection box 2. The impurity collection box 2 is detachably connected to the wall 1 and the return pipe 3 by screws. During the water flow, it first passes through the filter screen 8 to filter out leaves, garbage and other debris carried by the rainwater. The filtered rainwater passes through the filter screen 8 and enters the area below the drainage hopper 5, and finally flows into the drainage pipe 4 fixed at the bottom of the drainage hopper 5 to achieve drainage. At the same time, the inclined guide frame 94 fixed on the inner wall of the drainage hopper 5 guides some rainwater to the water tank 96 at the bottom of the threaded rod 98. As the water volume in the water tank 96 increases, its gravity overcomes the elastic force of the spring 914 on the outside of the guide rod 99 and drives the water tank 96 and the threaded rod 98 to move down synchronously. Because the threaded rod 98 is screwed to the inner threaded cylinder 92,The downward movement of the threaded rod 98 causes the internal threaded cylinder 92 to rotate, thereby rotating the arc-shaped scraper 93 and scraping away debris from the top surface of the filter screen 8. When the water-filled cylinder 96 descends, causing the drain hole 915 to disengage from the sealing sleeve 97, rainwater is discharged from the drain hole 915. With the weight reduced, the water-filled cylinder 96 rises under the reset action of the spring 914, resetting the threaded rod 98, the internal threaded cylinder 92, and the arc-shaped scraper 93, completing one automatic cleaning cycle. Similarly, a continuous cleaning process is achieved.

[0026] Specifically, a reinforcing seat 95 is fixedly installed on the inner wall of the drainage hopper 5 and the bottom of the guide frame 94, and a reinforcing plate 912 is fixedly installed on one side of the guide frame 94 and one side of the guide rod 99. The overall structure is stable through the reinforcement effect of the reinforcing seat 95 and the reinforcing plate 912.

[0027] Specifically, a water collection trough 6 is provided on the top of the drainage hopper 5 and the top of the wall 1, and an annular guide plate 7 is fixedly installed on the top of the inner wall of the drainage hopper 5. The cross-sections of the annular guide plate 7 and the water collection trough 6 are both designed to be inclined, so that the rainwater on the roof can be quickly collected into the drainage hopper 5 to avoid water accumulation.

[0028] The working principle of this utility model is as follows: rainwater is first collected through the water collection trough 6, and then guided into the interior of the drainage hopper 5 by the annular guide plate 7 fixed at the top of the inner wall of the drainage hopper 5.

[0029] As the water flows down, it first passes through the filter screen 8 fixed near the top inner wall of the drainage hopper 5. The filter screen 8 intercepts debris such as leaves and garbage carried by the rainwater. The filtered rainwater passes through the filter screen 8 and enters the area below the drainage hopper 5, eventually flowing into the drainage pipe 4 fixed at the bottom of the drainage hopper 5 to achieve drainage. At the same time, the inclined guide frame 94 fixed on the inner wall of the drainage hopper 5 guides some of the rainwater to the water-collecting cylinder 96 at the bottom of the threaded rod 98. As the water volume in the water-collecting cylinder 96 increases, its gravity overcomes the elastic force of the spring 914 on the outside of the guide rod 99, driving the water-collecting cylinder 96. The threaded rod 98 moves down synchronously. Since the threaded rod 98 is screwed to the internal threaded cylinder 92, the downward movement of the threaded rod 98 will cause the internal threaded cylinder 92 to rotate, thereby driving the arc-shaped scraper 93 to rotate with it and stick to the top surface of the filter screen 8 to scrape away debris. When the water tank 96 descends and the water hole 915 is separated from the sealing sleeve 97, rainwater is discharged from the water hole 915. After the weight of the water tank 96 is reduced, it rises under the reset action of the spring 914, driving the threaded rod 98, the internal threaded cylinder 92 and the arc-shaped scraper 93 to reset, completing one automatic cleaning cycle. Similarly, continuous cleaning is achieved.

[0030] The debris scraped off by the arc-shaped scraper 93 slides down the waste discharge trough 10 and enters the waste collection box 2 through the connection hole 11 at the top of the waste collection box 2 for collection. The inclined filter screen 12 performs secondary filtration on the small amount of rainwater entering. The filtered rainwater flows back to the drain pipe 4 through the return pipe 3 to achieve full drainage. The waste collection box 2 is detachably connected to the wall 1 and the return pipe 3 by screws, which makes it easy to open and clean the internal debris regularly.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
