Description

Technical Field

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

[0002] Traditional building drainage systems mostly employ gravity-based designs, relying on slope and pipe diameter to discharge rainwater. Common structures include roof gutters, vertical downpipes, and underground pipe networks. These systems are prone to drainage delays under heavy rainfall due to instantaneous flow overload, leading to roof flooding or basement backflow. Furthermore, they lack active interception mechanisms for suspended debris, resulting in a significant risk of pipe blockage. While existing technologies include anti-clogging measures such as filter structures or sedimentation wells, they generally suffer from high maintenance frequency and inconvenient dredging. Although some siphonic drainage devices can improve drainage efficiency, they impose stringent requirements on the building's structural load-bearing capacity and airtightness. With the promotion of the sponge city concept, the functional shortcomings of traditional drainage systems in rainwater resource utilization are becoming increasingly apparent. They cannot effectively integrate infiltration, storage, and purification modules, making it difficult to meet the sustainable rainwater management needs of green buildings.

[0003] The utility model patent with application number CN202422663389.X and publication number CN222120764U (hereinafter referred to as "Prior Art 1") discloses a building roof drainage structure, belonging to the field of building construction technology. It includes a roof surface, with a fence fixedly installed around the roof surface. Drainage holes are opened on the fence, and a filter plate is installed in the drainage hole. The filter plate completely covers the opening of the drainage hole. A receiving groove is opened on the inner top wall of the drainage hole. The receiving groove is used to receive the filter plate. A driving component is installed on the fence. The driving component is used to drive the filter plate to move towards the receiving groove.

[0004] The specification of prior art 1 discloses a building roof drainage structure. When in use, it can prevent debris in rainwater and snowmelt from clogging the drainage pipes and improve the drainage effect of the roof for rainwater and snowmelt. However, in actual application, when the mud and sand on the filter plate are scraped off by a scraper, the scraper will push the mud and sand that was originally on the filter plate into the holes of the filter plate, resulting in poorer drainage efficiency. Summary of the Invention

[0005] This utility model provides a building drainage device, which aims to solve the problem that in the prior art, when the drainage device scrapes the filter plate, it pushes the mud, sand and debris in the filter plate into the holes of the filter plate, resulting in a worse drainage efficiency of the filter plate.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A building drainage device includes a drainage channel, a drainage outlet, and an anti-clogging device; the drainage channel is used to install on the wall of a building rooftop, and the outer wall of the drainage channel is provided with a plurality of through drainage holes; the building rooftop is provided with a drainage outlet, and the drainage channel is located inside the drainage outlet; the anti-clogging device is used to unclog the drainage holes on the drainage channel.

[0008] The anti-clogging device includes a guide assembly, a sliding plate, a drain rod, an elastic element, and a pulling assembly. The sliding plate is slidably installed on the drainage channel. There are several drain rods, and the number and position of the drain rods correspond to the drainage holes. The drain rods are used to insert into the drainage holes. The guide assembly is set between the sliding plate and the drainage channel and is used to guide the sliding of the sliding plate. The elastic element is installed on the guide assembly. One end of the elastic element is connected to the sliding plate, and the other end is connected to the outer wall of the drainage channel.

[0009] Furthermore, a drain pipe is connected to the drainage channel, and the drain pipe is used to fix it to the side wall of the building.

[0010] Furthermore, the guide assembly includes a guide hole disposed on the drainage channel and a guide rod disposed on the slide plate, the guide rod being slidably connected to the guide hole, and the elastic element being sleeved on the guide rod.

[0011] Furthermore, a limit ring is provided on the guide hole, and a limit plate is provided at the end of the guide rod, the limit plate being used to contact the limit ring.

[0012] Furthermore, the pulling assembly includes a mounting plate, a first fixed pulley, and a second fixed pulley. A pull rope is fixedly installed on the mounting plate. The first fixed pulley is set on the building rooftop, and the second fixed pulley is set on the drain pipe. The pull rope hangs down after passing through the first and second fixed pulleys.

[0013] Furthermore, a limiting piece is provided at the end of the pull rope near the mounting plate, and the limiting piece is used to contact the end face of the mounting plate.

[0014] Furthermore, the first fixed pulley and the second fixed pulley are rotatably connected to the building roof and the drainage pipe respectively through a rotating seat.

[0015] Furthermore, the end of the unblocking rod has a frustum-shaped structure with a smaller front end and a larger rear end.

[0016] Furthermore, the elastic element is a spring, with one end of the spring connected to the slide plate and the other end connected to the outer wall of the drainage channel.

[0017] Furthermore, a pull handle is provided at the end of the pull rope.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model mainly includes a drainage channel, a drainage outlet, and an anti-clogging device. In actual use, during rainy days, rainwater accumulates on the roof of the building and flows out through the drainage holes in the drainage channel, thus achieving drainage. Since there is mud and sand in the rainwater and on the bottom surface of the roof, when the rainwater passes through the end face of the drainage channel, the mud and sand mainly flow out with the rainwater from the drainage holes. Therefore, the mud and sand will adhere to the drainage holes of the drainage channel, causing the drainage holes to become blocked. At this time, the user pulls the component, which pulls the sliding plate to slide on the drainage channel through the guide component. After the sliding plate slides, it drives the unblocking rod to insert into the drainage hole. When the user releases the pulling component, the sliding plate returns to its original position under the action of the elastic element. By repeatedly pulling and releasing the pulling component, the user can repeatedly insert the unblocking rod into the drainage hole, thereby unblocking the drainage hole and ensuring that the drainage efficiency of the drainage channel remains good.

Detailed Implementation

[0027] The present invention will be further described below with reference to embodiments. These embodiments are merely some, not all, of the present invention. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the protection scope of the present invention.

[0028] Please see Figures 1-5 As shown, this embodiment discloses a building drainage device, including a drainage channel 101, a drainage outlet 104, and an anti-clogging device; the drainage channel 101 is used to install on the wall of a building rooftop 102, and a plurality of through drainage holes 103 are provided on the outer wall of the drainage channel 101; the building rooftop 102 is provided with a drainage outlet 104, and the drainage channel 101 is disposed inside the drainage outlet 104; the anti-clogging device is used to unclog the drainage holes 103 on the drainage channel 101;

[0029] The anti-clogging device includes a guide assembly, a sliding plate 105, a drain rod 106, an elastic element 107, and a pulling assembly. The sliding plate 105 is slidably installed on the drain trough 101. There are several drain rods 106, and the number and position of the drain rods 106 correspond to the drain holes 103. The drain rods 106 are used to be inserted into the drain holes 103. The guide assembly is set between the sliding plate 105 and the drain trough 101 and is used to guide the sliding of the sliding plate 105. The elastic element 107 is installed on the guide assembly. One end of the elastic element 107 is connected to the sliding plate 105, and the other end is connected to the outer wall of the drain trough 101.

[0030] This utility model mainly includes a drainage channel 101, a drainage outlet 104, and an anti-clogging device. In actual use, during rainy days, rainwater accumulates on the rooftop of the building and flows out through the drainage hole 103 in the drainage channel 101, thus achieving drainage. Since rainwater and the bottom surface of the rooftop 102 contain silt and sand, when rainwater passes through the end face of the drainage channel 101, the silt and sand mainly flow out with the rainwater from the drainage hole 103. Therefore, the silt and sand will adhere to the drainage hole 103 of the drainage channel 101, causing the drainage hole 104 to become clogged. 3. Blockage: In this case, the user pulls the component to move the slide plate 105 across the drain trough 101 via the guide component. After the slide plate 105 slides, it drives the unblocking rod 106 into the drain hole 103. When the user releases the pulling component, the slide plate 105 returns to its original position under the action of the elastic element 107. By repeatedly pulling and releasing the pulling component, the user can repeatedly insert the unblocking rod 106 into the drain hole 103, thereby unblocking the drain hole 103 and ensuring that the drainage efficiency of the drain trough 101 remains good.

[0031] In some embodiments, a drain pipe 108 is connected to the drain trough 101, and the drain pipe 108 is used to fix to the side wall of the building.

[0032] In actual use, the purpose of setting up the drain pipe 108 is to facilitate the flow of rainwater into the ground sewer through the drain pipe 108, which is beneficial for rainwater discharge.

[0033] In some embodiments, the guide assembly includes a guide hole 109 disposed on the drainage groove 101 and a guide rod 110 disposed on the slide plate 105. The guide rod 110 is slidably connected to the guide hole 109, and the elastic element 107 is sleeved on the guide rod 110.

[0034] In actual use, the guide rod 110 slides inside the guide hole 109. The purpose of setting the guide hole 109 and the guide rod 110 is to make the slide plate 105 more stable when moving.

[0035] In some embodiments, a limiting ring 111 is provided on the guide hole 109, and a limiting plate 112 is provided at the end of the guide rod 110, the limiting plate 112 being used to contact the limiting ring 111.

[0036] In actual use, when the limiting rod is popped out by the elastic element 107, the limiting plate 112 and the limiting ring 111 fit together. The limiting ring 111 limits the entire guide rod 110. The purpose of setting the limiting ring 111 and the limiting plate 112 is to prevent the guide rod 110 from disengaging from the guide hole 109.

[0037] In some embodiments, the pulling assembly includes a mounting plate 113, a first fixed pulley 114 and a second fixed pulley 115. A pull rope 116 is fixedly mounted on the mounting plate 113. The first fixed pulley 114 is disposed on the building rooftop 102, and the second fixed pulley 115 is disposed on the drain pipe 108. The pull rope 116 hangs down after passing through the first fixed pulley 114 and the second fixed pulley 115.

[0038] In actual use, the user pulls the pull rope 116, and the pull rope 116 slides on the first fixed pulley 114 and the second fixed pulley 115. After pulling the pull rope 116, the slide plate 105 drives the guide rod 110 to slide inside the guide hole 109.

[0039] In some embodiments, a limiting piece 117 is provided at one end of the pull cord 116 near the mounting plate 113, the limiting piece 117 being used to contact the end face of the mounting plate 113.

[0040] In actual use, the end of the pull rope 116 is fixedly connected to the limiting piece 117. The limiting piece 117 is located on the back side of the mounting plate 113. After the pull rope 116 is pulled, the limiting piece 117 fits tightly against the mounting plate 113, thereby limiting the pull rope 116 and preventing the pull rope 116 from disengaging from the mounting plate 113.

[0041] In some embodiments, the first fixed pulley 114 and the second fixed pulley 115 are rotatably connected to the building rooftop 102 and the drain pipe 108 respectively via a rotating seat 118.

[0042] In actual use, both the building rooftop 102 and the drainage pipe 108 are equipped with rotating seats 118. The rotating seat 118 on the building rooftop 102 is rotatably mounted with a first fixed pulley 114, and the other rotating seat 118 is rotatably mounted with a second fixed pulley 115.

[0043] In some embodiments, the end of the unblocking rod 106 is a frustum-shaped structure with a smaller front end and a larger rear end.

[0044] In actual use, the purpose of setting the front end of the dredging rod 106 into a frustum shape is to facilitate the cooperation between the dredging rod 106 and the drainage hole 103, and also to facilitate the dredging of mud and sand by the small end of the dredging rod 106.

[0045] In some embodiments, the elastic element 107 is a spring, one end of which is connected to the slide plate 105 and the other end is connected to the outer wall of the drainage channel 101.

[0046] In actual use, the spring is sleeved on the guide rod 110, and its two ends are connected to the slide plate 105 and the drainage groove 101 respectively. When the slide plate 105 is pulled by the pull rope 116, it compresses the spring. When the user releases the pull rope 116, the reaction force of the spring resets the slide plate 105. The advantage of this setting is that the slide plate 105 has additional driving force, which makes it easier to reset the slide plate 105.

[0047] In some embodiments, the end of the pull rope 116 is provided with a pull handle 119.

[0048] In actual use, the purpose of setting the pull handle 119 is to make it easier for the user to grip the pull rope 116 and to make it easier for the user to pull the pull rope 116.
