Description

Technical Field

[0001] This invention relates to the field of drainage engineering technology, specifically to an automatic anti-backflow drainage system for pipelines. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. An automatic backflow prevention drainage system is a type of pipeline system design. Such systems typically include backflow check valves and other equipment to ensure smooth drainage and protect the environment and public health.

[0003] To prevent backflow in pipelines, various check valves have been invented. However, with prolonged use, these check valves gradually fail to close properly when backflow occurs, as dirt or impurities accumulate on their main surfaces. To address this issue, electrically triggered check valve mechanisms have been invented. However, their reliance on power limits their applications. This invention proposes an automatic backflow prevention and drainage system based on spring-loaded force. This system avoids the shortcomings of existing systems, effectively prevents backflow, requires no electricity, and has a wide range of applications. Summary of the Invention

[0008] Preferably, the outer wall of the pawl is engaged with a first ratchet, the inner wall of the first ratchet is fixedly connected with a first connecting post, and the right outer wall of the first connecting post is rotatably connected to the inner wall of the pipe body.

[0009] Preferably, a second gear is fixedly connected to the left outer wall of the first connecting column, a fixed wheel is meshed with the outer wall of the second gear, a fixed plate is provided at the top of the fixed wheel, and a spring is provided on the inner wall of the fixed plate.

[0010] Preferably, a valve is fixedly connected to the inner wall of the spring, the outer wall of the valve is rotatably connected to the inner wall of the fixed plate, a second connecting post is rotatably connected to the bottom end of the valve, the outer wall of the valve is fixedly connected to the inner wall of the fixed wheel, the bottom end of the second connecting post is located inside the pipe body, a third connecting post is fixedly connected to the bottom end of the valve, a ratchet is fixedly connected to the outer wall of the third connecting post, a second ratchet is engaged with the outer wall of the ratchet, a rotating post is fixedly connected to the inner wall of the second ratchet, the outer wall of the rotating post is rotatably connected to the inner wall of the valve, and a support ring is fixedly connected to the bottom end of the ratchet.

[0011] Preferably, a fixing ring is fixedly connected to the bottom end of the pipe body, and a support column is fixedly connected inside the fixing ring.

[0012] Preferably, the inner wall of the fixed ring is rotatably connected to a rotating ring, the rotating ring has a second sliding groove inside, and the outer wall of the support column is slidably connected to the inner wall of the second sliding groove.

[0013] Preferably, the inner wall of the rotating ring is fixedly connected to a mounting column, the outer wall of the mounting column is slidably connected to a filter plate, and the inner wall of the filter plate is rotatably connected to the bottom end of the fixed ring.

[0014] Preferably, the filter plate has holes inside, and a lever is fixedly connected to the outer wall of the rotating ring, with the upper surface of the lever slidably connected to the inside of the fixed ring.

[0015] Working principle: By rotating the valve, the outer spring on the main wall is tightened. When the main spring is tightened, it drives the second ratchet to rotate on the outer wall of the ratchet teeth, simultaneously causing the rotating pin to rotate on the inner wall of the valve. When the main spring is released, it drives the second ratchet to rotate, and the ratchet teeth engage the second ratchet, thereby driving the support ring to rotate. The rotation of the support ring causes the valve to rotate. When the valve rotates, it drives the fixed wheel to rotate. The fixed wheel rotates at the bottom of the fixed plate. When the fixed wheel rotates, it drives the second gear meshed on its outer wall to rotate. When the second gear rotates, it drives the first connecting pin fixedly connected to its inner wall to rotate. When the first connecting pin rotates, it drives the outer... The first ratchet on the wall rotates, causing the pawl to rotate and engage with it. Simultaneously, the spring resets. When the water level rises, the float is propelled by buoyancy and slides along the inner wall of the pipe. This movement causes the float rod on its outer wall to move up and down, moving along the inner wall of the sealing plate. This movement, in turn, causes the fixed post to move up and down, which in turn rotates the rack on its outer wall. The fixed post slides along the inner wall of the first groove. The rotation of the rack, in turn, rotates the first gear meshing with it on its outer wall. This rotation of the first gear, in turn, rotates the inner wall of the fixed post. The fixed bevel gear column rotates, causing it to rotate on the inner wall of the first baffle. This rotation drives the connecting rod, which is internally connected to the outer wall, to rotate. The connecting rod then rotates on the inner wall of the second baffle. This rotation of the connecting rod in turn drives the pawl to rotate, releasing the first ratchet and thus the spring. This release of the spring causes the valve to rotate, preventing blockage at the lower end of the pipe or backflow of sewage, reducing problems and losses caused by drainage issues. By moving the lever, the fixed rotating ring on the outer wall rotates. This rotating ring rotates on the inner wall of the fixed ring. When activated, the mounting column rotates, causing the filter plate, which is slidably connected to its outer wall, to rotate as well. The filter plate rotates at the bottom of the fixed ring, effectively intercepting various small impurities in the drainage, such as hair and fibers, reducing the risk of pipe blockage. By moving the lever, the rotating ring, fixed to its outer wall, rotates. This rotation, in turn, causes the mounting column to rotate, which in turn rotates the filter plate, which rotates at the bottom of the fixed ring. This allows for flexible flow adjustment based on actual drainage needs.This allows the drainage system to better meet the requirements of different usage scenarios.

[0016] This invention provides an automatic anti-backflow drainage system for pipelines. It has the following beneficial effects:

[0017] 1. This invention involves manually rotating a valve, which in turn tightens a spring and drives a fixed wheel to rotate. When the fixed wheel rotates, it drives a second gear, which in turn drives a first ratchet. Simultaneously, a pawl engages the first ratchet, causing it to rotate. A float then slides, causing a float rod to move up and down. The float rod's movement drives a rack, which in turn drives the pawl. This effectively prevents blockages at the lower end of the pipe or backflow of sewage, reducing the inconvenience and losses caused by drainage problems.

[0018] 2. This invention uses a sliding paddle block to drive a rotating ring, which in turn drives a mounting column to slide. This, in turn, drives a filter plate to rotate, which in turn drives the holes to rotate. Simultaneously, the filter plate rotates at the bottom of the fixed ring, thus effectively intercepting various small impurities in the drainage, such as hair and fibers, reducing the risk of pipe blockage.

[0019] 3. In this invention, the sliding of the toggle block causes the rotating ring to rotate, which in turn causes the mounting column to slide, which in turn causes the filter plate to rotate, and the filter plate to rotate the holes. At the same time, the filter plate rotates at the bottom of the fixed ring, thereby achieving flexible flow adjustment according to actual drainage needs, so that the drainage system can better meet the usage requirements in different scenarios.

[0020] 4. The entire system of this invention does not require electricity and can effectively prevent backflow in pipelines, making it widely applicable. Attached Figure Description
