Description

Technical Field

[0001] This utility model relates to the field of siphon drainage technology, specifically to a roof siphon drainage anti-clogging device. Background Technology

[0002] The roof siphon drainage anti-clogging device is a core auxiliary component specifically adapted to roof siphon drainage systems. Its core function is to ensure that the siphon drainage system can efficiently drain rainwater from the roof by using negative pressure to quickly remove rainwater, while intercepting impurities in the rainwater such as fallen leaves, mud, sand, and plastic debris. This prevents blockage of key components such as pipes, siphon buckets, elbows, and tees, avoiding system failure that could lead to water accumulation, leakage, or even structural damage to the roof.

[0003] Existing siphon drainage technology often uses a single anti-clogging cover to simply intercept impurities. However, the mud and small impurities generated by rainwater are not easily intercepted, and long-term use can easily cause sedimentation and blockage of the pipes. This paper proposes a roof siphon drainage anti-clogging device to solve the above problems. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a roof siphon drainage anti-clogging device.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A roof siphon drainage anti-clogging device includes a rainwater hopper, an anti-vortex guide hood fixedly connected to the middle of the inner wall of the rainwater hopper, a water inlet grille fixedly connected to the top of the anti-vortex guide hood, an anti-clogging cover fixedly connected to the upper surface of the rainwater hopper, and an anti-clogging pipe fixedly connected to the bottom of the rainwater hopper.

[0006] The beneficial effects of this utility model are: the anti-clogging cover, in conjunction with the water inlet grille, achieves dual interception of large and medium-sized impurities, reducing the number of impurities entering the device from the source and lowering the risk of clogging; the anti-vortex guide cover effectively suppresses vortex generation, ensuring a stable water flow state required for siphon drainage, avoiding siphon interruption due to vortex, and improving drainage efficiency; the rainwater hopper, as the core load-bearing component, organically integrates the anti-vortex guide cover, water inlet grille, anti-clogging cover, and anti-clogging pipe to form a complete preliminary drainage and anti-clogging structure.

[0007] Furthermore, a small impurity discharge pipe is fixedly connected to the middle of one side of the anti-blocking pipe, a connecting roller is fixedly connected to the middle of the inner wall of the anti-blocking pipe, and an inclined diversion plate connected to the anti-blocking pipe is fixedly connected to the top of the connecting roller.

[0008] The beneficial effects of the above scheme are: the setting of the small impurity discharge pipe provides a dedicated discharge channel for small impurities in rainwater, preventing small impurities from continuing to flow with rainwater in the anti-clogging pipe, preventing them from accumulating and clogging at pipe bends or narrow downstream parts, and the inclined diversion plate better guides the water flow to discharge small impurities into the pipe.

[0009] Furthermore, a rotating discharge fan wheel adapted to the small impurity discharge pipe is sleeved on the outer surface of the connecting roller, and an impurity collection pipe is fixedly connected to the output end of the small impurity discharge pipe.

[0010] The beneficial effects of the above solution are: when the rainfall is heavy, the water flow itself drives the rotating fan wheel to rotate, eliminating the need for additional power and achieving active separation and guidance of small impurities, which is energy-saving and efficient.

[0011] Furthermore, both sides of the inner wall of the impurity collection pipe are fixedly connected with sliding grooves, and a top cover is provided on the top of the impurity collection pipe.

[0012] The beneficial effects of the above solution are: the top cover can be opened, and with the track function of the slide, the subsequent filter screen can be quickly inserted into or removed from the impurity collection pipe through the slide, without disassembling the entire collection pipe, which greatly simplifies the operation process of impurity cleaning and filter screen replacement, reduces maintenance costs, and the top cover can prevent external debris such as fallen leaves and dust from entering the impurity collection pipe when closed.

[0013] Furthermore, both sides of the lower surface of the top cover are fixedly connected with connecting rods that are adapted to the sliding groove, and a filter screen is fixedly connected to the bottom of the connecting rod.

[0014] The beneficial effect of the above solution is that the filter screen, as the final interception component for small impurities, can completely retain the small impurities that are discharged into the pipeline within the collection pipeline, preventing them from flowing out of the impurity collection pipeline with the water flow, and ensuring that the small impurities are completely separated.

[0015] Furthermore, the output end of the anti-blocking pipe is fixedly connected to a connecting pipe.

[0016] The beneficial effects of the above solution are: the connecting pipe effectively connects the anti-blocking pipe to the downstream drainage system, avoiding increased water flow resistance caused by pipe size mismatch or uneven interface, ensuring smooth rainwater flow, and maintaining stable negative pressure of siphon drainage.

[0017] Furthermore, the output end of the impurity collection pipe is fixedly connected to a drain pipe that is connected to the connecting pipe.

[0018] The beneficial effects of the above solution are: by connecting the impurity collection pipe and the connecting pipe through the drainage pipe, the rainwater after the small impurities are separated can return to the main drainage system, avoiding water accumulation in the impurity collection pipe, and improving the drainage efficiency and functionality of the entire device.

Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details.

[0026] Example 1 Figure 1 This utility model provides an overall structural diagram of a roof siphon drainage anti-clogging device. Figure 2 The above is a top view of the overall structure of this utility model. The device includes: a rainwater hopper 1, an anti-vortex guide hood 2 fixedly connected to the middle of the inner wall of the rainwater hopper 1, a water inlet grille 3 fixedly connected to the top of the anti-vortex guide hood 2, an anti-clogging cover 4 fixedly connected to the upper surface of the rainwater hopper 1, and an anti-clogging pipe 5 fixedly connected to the bottom of the rainwater hopper 1.

[0027] Rainwater from the roof first comes into contact with the top anti-clogging cover 4 of the device. The anti-clogging cover 4 initially blocks larger impurities in the rainwater, preventing them from directly entering the rainwater hopper 1 and causing large-scale blockages. After initial blocking, the rainwater enters the rainwater hopper 1 and flows through the top inlet grille 3. The inlet grille 3 further filters medium and large impurities in the rainwater and guides the rainwater into the rainwater hopper 1 in an orderly manner. Under the action of the anti-vortex guide cover 2, the rainwater entering the rainwater hopper 1 avoids the formation of vortex flow. Because vortices would disrupt the stable formation of the siphon effect, the anti-vortex guide cover 2 changes the direction and trajectory of the rainwater flow, keeping the rainwater in a stable laminar or turbulent state, ensuring the negative pressure conditions required for siphon drainage. After being guided and initially filtered, the rainwater enters the subsequent drainage system through the anti-clogging pipe 5 at the bottom of the rainwater hopper 1, starting the siphon drainage process.

[0028] Figure 3 This is a cross-sectional view of the overall structure of this utility model, as shown below. Figure 3 As shown, a small impurity discharge pipe 6 is fixedly connected to the middle of one side of the anti-blocking pipe 5, a connecting roller 7 is fixedly connected to the middle of the inner wall of the anti-blocking pipe 5, and an inclined diversion plate 16 connected to the anti-blocking pipe 5 is fixedly connected to the top of the connecting roller 7.

[0029] When rainwater flows through the anti-clogging pipe 5, small impurities still contained in the rainwater flow with the water. When the water flows past the small impurities in the middle of one side of the anti-clogging pipe 5 and enters the pipe 6 interface, the connecting roller 7 fixed in the middle of the inner wall of the anti-clogging pipe 5 provides fixed support for the subsequent rotating parts, waiting to cooperate with the rotating discharge fan wheel 8 to separate the small impurities. The small impurity discharge pipe 6 serves as the discharge channel for small impurities, initially constructing a small impurity diversion path to avoid the accumulation of small impurities in the anti-clogging pipe 5. Through the inclined diversion plate 16, the small impurities in the rainwater are better discharged into the small impurity discharge pipe 6, preventing the rotating discharge fan wheel 8 from missing them.

[0030] The outer surface of the connecting roller 7 is fitted with a rotating discharge fan wheel 8 that is compatible with the small impurity discharge pipe 6, and the output end of the small impurity discharge pipe 6 is fixedly connected to an impurity collection pipe 9.

[0031] When rainwater carrying small impurities flows through the anti-clogging pipe 5, if the amount of rainwater is large, the water flow impacts the rotating discharge fan wheel 8 sleeved on the outer surface of the connecting roller 7. Since the rotating discharge fan wheel 8 is adapted to the small impurity discharge pipe 6, the kinetic energy of the water flow drives the rotating discharge fan wheel 8 to rotate around the connecting roller 7. During the rotation, the blades of the rotating discharge fan wheel 8 push the small impurities in the rainwater toward the inlet of the small impurity discharge pipe 6, so that the small impurities enter the impurity collection pipe 9 fixed at its output end through the small impurity discharge pipe 6, thereby separating the small impurities from the rainwater. The rainwater after the small impurities are separated continues to flow downward along the anti-clogging pipe 5 and enters the subsequent drainage stage.

[0032] Example 2 Based on Embodiment 1, the present invention can be further improved as follows: Figure 6 This is a structural diagram of the impurity collection pipeline of this utility model, such as... Figure 6 As shown, both sides of the inner wall of the impurity collection pipe 9 are fixedly connected to the sliding grooves 10, and the top of the impurity collection pipe 9 is provided with a top cover 11.

[0033] After small impurities enter the impurity collection pipe 9 through the inlet pipe 6, the sliding grooves 10 on both sides of the inner wall of the impurity collection pipe 9 provide a track for the subsequent installation and movement of the filter screen 13. The top cover 11 of the impurity collection pipe 9 can be opened or closed. When opened, it is convenient to install or remove the filter screen 13. When closed, it prevents external debris from falling into the impurity collection pipe 9, avoiding secondary pollution or blockage of the collection pipe.

[0034] Both sides of the lower surface of the top cover 11 are fixedly connected with connecting rods 12 that are compatible with the slide groove 10, and the bottom of the connecting rods 12 is fixedly connected with a filter screen 13.

[0035] When small impurities enter the impurity collection pipe 9 with the water flow, the filter screen 13 filters and intercepts the small impurities again, causing them to remain on the filter screen 13, while the water flows through the filter screen 13 and continues to flow downward. When it is necessary to clean the impurities, open the top cover 11, and by pulling the top cover 11 upward, drive the connecting rod 12 to move upward along the slide groove 10, thereby removing the filter screen 13 from the impurity collection pipe 9. After cleaning the impurities on the filter screen 13, it can be reinstalled in its original position for reuse.

[0036] The output end of the anti-blocking pipe 5 is fixedly connected to the connecting pipe 15.

[0037] Rainwater that has undergone preliminary treatment by the anti-blocking pipe 5 flows out from the output end of the anti-blocking pipe 5 and enters the connecting pipe 15 that is fixedly connected to it.

[0038] The output end of the impurity collection pipe 9 is fixedly connected to a drain pipe 14 that is connected to the connecting pipe 15.

[0039] The impurity collection pipe 9 is connected to the drain pipe 14 at the output end and connected to the connecting pipe 15. The filtered clean rainwater is collected in the connecting pipe 15 and merged with the rainwater transported by the anti-blockage pipe 5, and together they enter the downstream siphon drainage system.
