Description

Technical Field

[0001] The present invention relates to the technical field of drainage, and specifically to a siphon drainage device with adaptive flow regulation. Background Art

[0002] As an important technology in the field of building drainage, the siphon drainage system has significant application value in roof drainage projects. With the acceleration of urbanization and the frequent occurrence of extreme weather events, the building drainage system faces new challenges. The mainstream siphon drainage devices on the current market generally adopt a fixed pipe diameter design, and their performance parameters are often set based on a specific rainfall intensity, which has obvious limitations in practical applications.

[0003] In the prior art, the traditional siphon drainage system mainly has the following technical bottlenecks: First, when dealing with changes in rainfall intensity, the system lacks effective adaptive adjustment ability and is difficult to balance the drainage efficiency during light rain and overload protection during heavy rain. Second, to achieve flow control, most systems need to be equipped with additional electric control valves and sensors, which not only increases the structural complexity but also improves the energy consumption and maintenance difficulty. In addition, when encountering drastic fluctuations in water level, the siphon effect of the system is prone to instability, affecting the continuity of drainage. These problems have restricted the application effect of siphon drainage technology in high - demand scenarios to a certain extent. In view of the above technical defects, the industry urgently needs to develop an improved solution that can autonomously respond to environmental changes and has a simple and reliable structure.

[0004] Summary of the Invention Autonomously respond to environmental changes The purpose of the present invention is to solve the above problems, thereby providing a siphon drainage device with adaptive flow regulation that can autonomously respond to environmental changes.

[0005] The technical solution adopted by the present invention to solve the above problems is: A siphon drainage device with adaptive flow regulation, including a horizontal water guide pipe. One end of the water guide pipe is connected to an inverted L - shaped drain pipe. A water level sensing and regulating mechanism and a rainfall sensing and regulating mechanism are respectively arranged on the water guide pipe. Flow regulating mechanisms are respectively provided in the water level sensing and regulating mechanism and the rainfall sensing and regulating mechanism. A positioning plate is arranged between the water level sensing and regulating mechanism and the rainfall sensing and regulating mechanism. A pipe diameter regulating component for controlling the flow - through cross - sectional area of the water guide pipe is arranged in the inner cavity of the water guide pipe, and the pipe diameter regulating component is connected to the flow regulating mechanism.

[0006] The present invention adopting the above technical solution, compared with the prior art, has the following prominent features: The device adopts a dual-feedback regulation mechanism to achieve autonomous regulation of the drainage flow. Through the coordinated action of the water level sensing and regulating mechanism and the rainfall sensing and regulating mechanism, it can dynamically adjust the flow cross-sectional area of the water guide pipe according to the actual drainage demand, solving the problem of inflexible flow regulation in traditional systems. Its unique pipe diameter adjustment component is linked and coordinated with the flow regulation mechanism, and can complete adaptive adjustment without an external power source, significantly reducing the system energy consumption and maintenance difficulty. Compared with the traditional design, while maintaining the stability of the siphon effect, this device can achieve a rapid response to water level fluctuations through mechanical feedback control, avoiding the phenomenon of drainage interruption caused by water level changes.

[0007] As a preferred embodiment, a further technical solution of the present invention is: Furthermore, the water level sensing and regulating mechanism includes a cylinder body, which is longitudinally placed and fixed in the drain pipe in the middle. The bottom of the cylinder body is an open structure and is slidably connected with a sliding rod. The bottom end of the sliding rod is connected with a buoyancy plate. The rainfall sensing and regulating mechanism and the water level sensing and regulating mechanism have the same cylinder structure installed upside down. The top of the sliding rod of the rainfall sensing and regulating mechanism is connected with a tray. Return springs are sleeved on the rod bodies of the sliding rods between the buoyancy plate and the cylinder body of the water level sensing and regulating mechanism, and between the tray and the cylinder body of the rainfall sensing and regulating mechanism. The water level sensing and regulating mechanism adopts a longitudinally arranged cylinder structure, combined with the open design at the bottom, enabling the sliding rod to achieve smooth axial movement. The combination of the buoyancy plate and the return spring can effectively sense the water level change and automatically reset. When the water level rises, it pushes the sliding rod to compress the return spring, and when the water level drops, the return spring pushes the sliding rod to reset, realizing automatic adjustment under power-free conditions. The rainfall sensing and regulating mechanism and the water level sensing and regulating mechanism form a complementary dual-sensing system. The tray of the rainfall sensing and regulating mechanism senses the amount of rainfall and then drives the sliding rod to move.

[0008] Furthermore, a sealing ring is provided between the sliding rod and the open end of the cylinder body where it is located. The setting of the sealing ring not only ensures sliding sealing but also reduces the movement resistance.

[0009] Furthermore, the flow regulation mechanism includes a push block located inside the cylinder body and fixed to the end of the sliding rod. An annular expansion airbag is provided in the middle of the inner cavity of the cylinder body. The push block is stepped and movably arranged between the expansion airbags. The stepped push block design can adjust the airbag compression amount in stages, forming a continuously adjustable mechanical-pneumatic conversion system. The displacement of the push block is proportional to the change of the external environment, avoiding the hysteresis problem of electric regulation.

[0010] Furthermore, the pipe diameter adjustment component includes an airbag ring on the inner wall of the water guide pipe on the side away from the drain pipe. A ventilation pipe is provided between the airbag ring and the expansion airbag. The airbag ring and the expansion airbag form a closed gas path, and the air pressure change can be immediately transmitted to the adjustment part to achieve long-distance lossless control. The expansion and contraction of the airbag ring change the effective diameter of the water guide pipe.

[0011] Further, a clamping plate for fixing is longitudinally arranged at the bottom of the water guide pipe close to the drain pipe side. The longitudinally arranged clamping plate enhances the installation stability of the system.

[0012] Further, a horizontal telescopic rod is arranged at the upper part of the water level induction and adjustment mechanism. A longitudinal water pipe is connected to the end of the telescopic rod. A connecting pipe is arranged at the bottom end of the water pipe. Magnets for matching use are respectively arranged at the end parts of the water guide pipe and the connecting pipe. The opposite-pole magnets are inserted into each other to achieve quick disassembly and assembly, which is more corrosion-resistant than mechanical buckles.

[0013] Further, a handle is arranged on the water pipe. Description of the Drawings

Detailed Embodiment

[0015] The present invention will be further described below in conjunction with embodiments. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0016] A siphon drainage device with adaptive flow regulation includes a horizontal water guide pipe 1. One end of the water guide pipe 1 is connected to an inverted L-shaped drain pipe 2. A water level induction and adjustment mechanism and a rain amount induction and adjustment mechanism are respectively arranged on the water guide pipe 1. Flow regulation mechanisms are respectively arranged in the water level induction and adjustment mechanism and the rain amount induction and adjustment mechanism. A positioning plate 3 is arranged between the water level induction and adjustment mechanism and the rain amount induction and adjustment mechanism. A pipe diameter adjustment component for controlling the flow cross-sectional area of the water guide pipe 1 is arranged in the inner cavity of the water guide pipe 1. The pipe diameter adjustment component is connected to the flow regulation mechanism. The water level induction and adjustment mechanism is located on the side of the rain amount induction and adjustment mechanism away from the drain pipe 2.

[0017] Furthermore, the water level sensing and regulating mechanism includes a cylinder body 4. The cylinder body 4 is longitudinally placed and fixed in the middle on the drain pipe 2. The bottom of the cylinder body 4 is an open structure and is slidably connected with a slide rod 5. The bottom end of the slide rod 5 is connected with a buoyancy plate 6. The rain sensing and regulating mechanism and the water level sensing and regulating mechanism have the same cylinder body 4 structure installed in an inverted manner. The top of the slide rod 5 of the rain sensing and regulating mechanism is connected with a tray 7. The tray 7 is a disk-shaped mechanism with edges around it. Small drain holes are provided on the side surface of the tray 7. Return springs 8 are sleeved on the rod bodies of the slide rod 5 between the buoyancy plate 6 and the cylinder body 4 of the water level sensing and regulating mechanism, and between the tray 7 and the cylinder body 4 of the rain sensing and regulating mechanism. The water level sensing and regulating mechanism adopts a longitudinally arranged cylinder body 4 structure. With the open design at the bottom, the slide rod 5 can achieve smooth axial movement. The combination of the buoyancy plate 6 and the return spring 8 can effectively sense the water level change and automatically reset. When the water level rises, the slide rod 5 is pushed to compress the return spring 8. When the water level drops, the return spring 8 pushes the slide rod 5 to reset, realizing automatic adjustment under the condition of no power. The rain sensing and regulating mechanism and the water level sensing and regulating mechanism form a complementary dual sensing system. The tray 7 of the rain sensing and regulating mechanism senses the amount of rainwater and then drives the slide rod 5 to move.

[0018] Furthermore, a sealing ring is provided between the slide rod 5 and the open end of the cylinder body 4 where it is located. The setting of the sealing ring not only ensures sliding sealing performance but also reduces the movement resistance.

[0019] Furthermore, the flow regulating mechanism includes a push block 9 located inside the cylinder body 4 and fixed at the end of the slide rod 5. An annular expansion airbag 10 is provided in the middle of the inner cavity of the cylinder body 4. The push block 9 is stepped and movably arranged between the expansion airbags 10. The cross-sectional area of the push block 9 decreases from the outside to the side of the water guide pipe 1. The stepped push block 9 design can adjust the airbag compression amount in stages, forming a continuously adjustable mechanical-pneumatic conversion system. The displacement of the push block 9 is proportional to the change of the external environment, avoiding the hysteresis problem of electric regulation.

[0020] Furthermore, the pipe diameter regulating component includes an airbag ring 11 located on the inner wall of the water guide pipe 1 on the side far from the drain pipe 2. It adopts a three-layer composite structure to prevent wear: inner layer (contact layer): hydrogenated nitrile rubber with a Shore hardness of 50-60; middle layer (reinforcement layer): aramid fiber woven mesh with a thickness of 0.2 mm; outer layer (protective layer): polyurethane elastomer; A ventilation pipe 12 is provided between the airbag ring 11 and the expansion airbag 10. The airbag ring 11 and the expansion airbag 10 form a closed gas path, and the air pressure change can be immediately conducted to the regulating part, realizing remote lossless control. The expansion and contraction of the airbag ring 11 change the effective diameter of the water guide pipe 1.

[0021] Furthermore, a clamping plate 13 for fixing is longitudinally provided at the bottom of the water guide pipe 1 on the side close to the drain pipe 2. The clamping plate 13 is fixed to the wall through bolts. The longitudinally arranged clamping plate 13 enhances the installation stability of the system.

[0022] Furthermore, a horizontal telescopic rod 14 is provided at the upper part of the water level sensing and adjusting mechanism. The end of the telescopic rod 14 is connected to a longitudinal water pipe 15. A connecting pipe 16 is provided at the bottom end of the water pipe 15. The connecting pipe 16 is a flexible pipe. Magnets for cooperative use are respectively provided at the end parts of the water guide pipe 1 and the connecting pipe 16. The opposite-pole magnets are inserted into each other to achieve quick disassembly and assembly, which is more corrosion-resistant than mechanical buckles.

[0023] Furthermore, a handle 17 is provided on the water pipe 15.

[0024] The water guide pipe 1 can be directly connected to the pipeline of the existing siphon rainwater system, or quickly docked with the connecting pipe 16 through a magnetic attraction connection method. When manual siphon startup is required, the operator can repeatedly pull the water pipe 15 through the handle 17 to form a negative pressure difference in the pipeline, thereby establishing an initial siphon effect, enabling the water flow to be guided along the water guide pipe 1 to the drain pipe 2. When the rainfall increases, the rainwater impacts the tray 7 of the rain volume sensing and adjusting mechanism, causing it to drive the sliding rod 5 to move downward, compressing the return spring 8 and squeezing the telescopic airbag 10 through the stepped push block 9. At the same time, when the accumulated water level rises, the buoyancy plate 6 is pushed by the buoyancy force to drive the sliding rod 5 of the water level sensing and adjusting mechanism to move upward, also compressing the return spring 8 and driving the push block 9 to squeeze the telescopic airbag 10. The air pressure changes generated by the two adjusting mechanisms are conducted through the ventilation pipe 12 to the airbag ring 11 in the inner cavity of the water guide pipe 1, causing it to expand and contract, thereby dynamically adjusting the flow cross-sectional area of the inner core pipe. When the rainfall decreases or the water level drops, the return spring 8 pushes the sliding rod 5 to reset, the telescopic airbag 10 returns to its original state, the airbag ring 11 releases the extrusion of the inner core pipe, and the flow area automatically recovers. The entire adjustment process does not require external power and realizes the coordinated control of two parameters (water level + rain volume) through mechanical feedback, solving the problems of lag in adjustment and dependence on manual intervention in traditional siphon drainage systems. The magnet design at the ends of the water guide pipe 1 and the connecting pipe 16 facilitates quick disassembly and assembly, and can not only be directly connected to the existing siphon system for automatic adjustment, but also be manually operated through the water pipe 15 for manual intervention, forming a dual operation mode. The device realizes precise control of the drainage flow through physical sensing and mechanical transmission, effectively avoiding the phenomenon of reduced drainage efficiency or siphon interruption caused by untimely adjustment in traditional systems.
