Description

Technical Field

[0001] The invention belongs to the field of rainwater infiltration, and in particular relates to a siphon type rainwater drainage system Background Art

[0002] Rainwater infiltration is an effective method of using rainwater to replenish groundwater. It is caused by the increase in construction across the country, which has led to too much hardened ground and the inability of rainwater to return to the ground. Infiltration can also be used in combination with rainwater collection and reuse. Rainwater infiltration can be carried out in the form of green space infiltration, permeable paved ground infiltration, shallow ditch and depression infiltration, shallow ditch infiltration channel combination infiltration, infiltration trench, infiltration well, infiltration pool, infiltration pipe-discharge system, etc. As the most important part of the siphon roof rainwater drainage system, the pipeline must ensure the safety, reliability, efficient and continuous operation of the system. As a special drainage system, the siphon system must ensure complete sealing and complete fire prevention measures for its pipelines, and reduce noise as much as possible, absorb vibration, resist external impact forces, and meet the maximum resistance to deformation caused by temperature changes.

[0003] Complete anti-leakage of the pipe does not mean that the system is sealed. Once a siphon system leaks, it is not easy to find. When a sudden heavy rain occurs, the entire system may collapse immediately. Of course, a small leak does not necessarily cause a leak, but it is enough to cause an air leak. Once an air mass appears in the drainage pipe, the efficiency of the siphon drainage is immediately greatly reduced, and in severe cases, it may even destroy the siphon effect. Summary of the invention

[0004] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a siphon type rainwater drainage system. The present invention can prevent the air mass inside the pipe in the siphon type rainwater drainage system from affecting the drainage efficiency and at the same time increase the drainage channel in the water pipe to make the drainage efficiency higher.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0029] Furthermore, a hose 44 is fixedly provided on one side of the partition plate 32 . The hose 44 is connected to the shrink film 34 . The hose 44 passes through the through hole 19 and extends into the second water pipe 18 .

[0030] How it works

[0031] Rainwater falls on the mounting plate 10 , flows into the infiltration port 11 through the siphon drain port 12 , and is collected in the siphon pipe 13 .

[0032] When the rainwater is small, the amount of water collected in the siphon pipe 13 is not much. At this time, the single-floating sliding tube 20 cannot slide into the through hole 19 under the elastic force of the spring 29. At this time, the single-floating sliding tube 20 is in the first water pipe 17, and the collected water flows into the opening at one end of the single-floating sliding tube 20 and accumulates in the single-floating sliding tube 20. When the water flow accumulates in the single-floating sliding tube 20 and the water volume gradually increases, the liquid level rises. Since the floating plate 40 has buoyancy in the water, the water blocking plate 39 and the sliding rod 42 can float upward. When the liquid level does not reach a certain height, the sliding rod 42 always remains inclined and one end of the sliding rod 42 abuts against the lower end surface of the mounting block 36, limiting the floating plate 40, so that the floating plate 40 cannot float up, and the opening of the shrink film 34 cannot be opened.

[0033] As the liquid level gradually rises, the annular floating plate 43 gradually slides upward along the slide bar 42 due to the action of buoyancy. During the upward sliding process of the annular floating plate 43, the slide bar 42 can gradually return to the normal position. When the annular floating plate 43 slides to the highest point, the slide bar 42 is perpendicular to the floating plate 40. At this time, one end of the slide bar 42 is opposite to the second slide groove 38 and can slide in the second slide groove 38. Due to the buoyancy of the floating plate 40, the water blocking plate 39 slides in the first slide groove 37, and the slide bar 42 slides in the second slide groove 38. The opening of the shrink film 34 is opened, and water flows in through the shrink film 34. Since the amount of water outside the shrink film 34 is sufficient, there is no air inside when flowing into the shrink film 34, so the siphon effect can be triggered and the siphon efficiency of the siphon effect can be improved.

[0034] When the rain is heavy, the amount of water collected in the siphon pipe 13 is too much, and the water flow rate is fast. Under the impact force of the water flow, it hits the impact plate on one side of the single-floating sliding tube 20, causing the single-floating sliding tube 20 to overcome the elastic force of the spring 29 and slide into the through hole 19. When the single-floating sliding tube 20 slides to the bottom of the through hole 19, the second sliding tube 31 is squeezed by the bottom so that the second sliding tube 31 slides into the single-floating sliding tube 20. When sliding to the bottom, the fixed block 30 abuts against the bottom of the slide rail 35. At this time, the through hole on one side of the fixed block 30 is opened, and the water flow can flow in through the through hole on one side of the fixed block 30 and the shrink film 34. While the water flow hits the single-floating sliding tube 20, it gradually fills the single-floating sliding tube 20, and the impact produces The air can float up and flow out from the exhaust port 28 and enter the water inlet tank 23 along the arc surface of the arc-shaped air collecting tank 21. At the same time, the water flow can also enter the water inlet tank 23. Under the buoyancy of the water, the pressure ball 25 moves up to block the opening at the lower end of the exhaust groove 26. The gas floats up through the water flow. When the internal gas gradually increases, the air pressure in the active cavity 24 increases to squeeze the pressure ball 25 downward, so that the opening at the lower end surface of the exhaust groove 26 is opened, and the gas enters the exhaust groove 26 at the same time. When the air pressure in the exhaust groove 26 reaches a certain value, the one-way exhaust valve 27 can be opened to let the gas flow out, which can effectively avoid the sudden occurrence of heavy rain, which may immediately cause the entire system to collapse, and then the rainwater from the roof cannot be discharged in time.
