Description

Technical Field

[0001] The utility model relates to the technical field of siphon pressure rainwater pipes, in particular to a siphon pressure rainwater pipe disconnecting and connecting device. Background Art

[0002] There are two types of building rainwater drainage systems: gravity flow rainwater drainage system and siphon pressure flow rainwater drainage system. In the siphon pressure flow rainwater drainage system, when the roof rainwater height does not exceed the rainwater bucket height at the beginning of rainfall, the working condition of the entire drainage system is the same as that of the gravity flow drainage system. As the rainfall continues, when the roof rainwater height exceeds the rainwater bucket height, the scientifically designed anti-vortex rainwater bucket is used to control the rainwater flow entering the rainwater bucket and adjust the flow state to reduce the vortex, thereby greatly reducing the amount of air entrained when the rainwater enters the drainage system, making the drainage pipe in the system full flow state. By using the height of the building roof and the potential energy of the rainwater, a siphon effect is formed when the rainwater flows continuously through the rainwater suspension pipe and turns into the rainwater riser and falls, and the maximum negative pressure is present in the pipe at this location. The roof rainwater is discharged to the outside at a high flow rate under the suction effect of the negative pressure in the pipe.

[0003] However, the prior art still has the following problems:

[0004] First, most siphonic rainwater drainage systems are used for direct drainage, and the water output cannot be adjusted. The drainage flow rate cannot be adjusted for light rain or heavy rain, which seriously limits the use of siphonic rainwater drainage systems.

[0005] Secondly, the water flow velocity at the end of the siphon rainwater drainage system is relatively high, and the kinetic energy of the water is large, so the outlet water will backflow. Most rainwater drainage systems have anti-backflow equipment at the very end, but it will cause blockage over time. Most of the anti-backflow equipment cannot be disassembled and cleaned, which seriously affects the drainage efficiency.

[0006] In view of the above problems, the inventor proposes a siphon pressure rainwater pipe disconnecting device to solve the above problems. Utility Model Content

[0025] The middle portion of the outer surface of the water collecting pipe 2 is curved.

[0026] By adopting the above technical solution, the middle part of the outer surface of the water collecting pipe 2 is curved, so that the rainwater can fall in a buffered manner.

[0027] Two water hammer pipes 6 are connected through the outer surface of the water collecting pipe 2 , and check valves 7 are provided on the inner walls of the two water hammer pipes 6 .

[0028] By adopting the above technical solution, rainwater enters the inner walls of the two water hammer tubes 6 respectively. Because the pressure of rainwater in the inner wall of the water collecting pipe 2 lifts the check valve 7, the impact of rainwater on the inner wall of the water collecting pipe 2 can be reduced under the action of inertia.

[0029] The inner wall of the water collecting pipe 2 is provided with three deceleration screen frames 8 distributed at equal intervals. One end of the three deceleration screen frames 8 is penetrated and connected with a second rotating shaft 9. The two ends of the three second rotating shafts 9 are rotatably connected to the inner walls of the water collecting pipe 2 on both sides.

[0030] By adopting the above technical solution, rainwater drives the three deceleration screen frames 8 to rotate and can slowly move the rainwater forward.

[0031] Four semicircular plates 10 are fixedly connected to the inner wall of the water collecting pipe 2, wherein every two semicircular plates 10 on the same vertical side are respectively distributed upward and downward.

[0032] By adopting the above technical solution, the four semicircular plates 10 can reduce the impact force of rainwater.

[0033] A filter screen 11 is fixedly provided at one end of the shell cover 5 , and a rubber non-return sleeve 12 is provided on the inner wall of the shell cover 5 .

[0034] By adopting the above technical solution, the filter screen 11 can prevent debris from entering, and rainwater flows out from the bottom end of the rubber check sleeve 12, but water cannot enter from the outside, thereby preventing rainwater from flowing back.

[0035] A through second through groove 37 is provided at one end of the shell 31, four third through grooves 13 distributed in a circular array are provided on the outer surface of the water collecting pipe 2, and four fourth through grooves 14 distributed in a circular array are provided on the outer surface of the shell cover 5. One end of the block 35 is respectively fitted with the inner walls of the third through groove 13 and the fourth through groove 14.

[0036] By adopting the above technical solution, the top end of the block 35 slides on the outer surface of the shell cover 5, and the top end of the block 35 slides from the inner wall of the third through groove 13 opened in the water collecting pipe 2, and then slides out from the inner wall of the fourth through groove 14 opened in the shell cover 5, thereby separating the water collecting pipe 2 from the shell cover 5.

[0037] Embodiment 2: Figure 5-8 As shown, the regulating device 4 includes a fixed slot plate 41, the bottom end of the fixed slot plate 41 is fixedly connected to the outer surface of the water collecting pipe 2, one end of the fixed slot plate 41 is fixedly connected to a support plate 42, one end of the support plate 42 is fixedly connected to a cylinder 43, one end of the fixed slot plate 41 is provided with a first through slot 44, and the inner wall of the first through slot 44 is slidably connected to a tooth plate 45, one end of the tooth plate 45 is fixedly connected to one end of the cylinder 43, the outer surface of the tooth plate 45 is meshingly connected to a gear 46, the bottom end of the gear 46 is fixedly connected to a rotating rod 47, and the outer surface of the rotating rod 47 is fixedly connected to a baffle 48.

[0038] By adopting the above technical solution, the regulating device 4 is adjusted according to the amount of rainwater, and the cylinder 43 in the regulating device 4 is turned on. The output end of the cylinder 43 pushes out the tooth plate 45, and the tooth plate 45 moves in the inner wall of the first through groove 44 opened in the fixed groove plate 41. The movement of the tooth plate 45 drives the gear 46 to rotate, and the rotation of the gear 46 drives the rotating rod 47 to rotate. The rotation of the rotating rod 47 drives the baffle 48 to rotate in the inner wall of the water collecting pipe 2. The angle of the baffle 48 can be adjusted to control the flow rate of rainwater.

[0039] The upper and lower ends of the rotating rod 47 are rotatably connected to the upper and lower inner walls of the water collecting pipe 2 respectively.

[0040] By adopting the above technical solution, the rotating rod 47 rotates in the inner wall of the water collecting pipe 2.

[0041] Working principle: when it rains, rainwater continuously flows through the rainwater bucket 1 and falls into the water collecting pipe 2, forming a siphon effect. The rainwater flows downward from the inner wall of the water collecting pipe 2. The middle part of the outer surface of the water collecting pipe 2 is curved, which can allow the rainwater to fall in a buffered manner. The rainwater enters the inner walls of the two water hammer tubes 6 respectively. Because of the pressure in the inner wall of the water collecting pipe 2, the rainwater lifts the check valve 7, which can reduce the impact of the rainwater on the inner wall of the water collecting pipe 2 under the action of inertia. The rainwater drives the three deceleration screen frames 8 to rotate to slowly move the rainwater forward. The four semicircular plates 10 can reduce the impact force of the rainwater. The regulating device 4 is adjusted according to the size of the rainwater. The cylinder 43 in the regulating device 4 is turned on. The output end of the cylinder 43 pushes out the tooth plate 45. The tooth plate 45 moves in the inner wall of the first through groove 44 opened in the fixed groove plate 41. The movement of the tooth plate 45 drives the gear 46 to rotate. The rotation of the gear 46 drives the rotating rod 47 to rotate. The rotation of 47 drives the baffle plate 48 to rotate in the inner wall of the water collecting pipe 2. The angle of the baffle plate 48 can be adjusted to control the flow rate of rainwater. When rainwater flows out, it flows out from the bottom end of the rubber check sleeve 12, but water cannot enter from the outside, so rainwater backflow can be prevented. When the anti-backflow equipment needs to be disassembled and cleaned, the pressure rod 34 is pressed, and the pressure rod 34 drives the fixed column 33 to rotate. The fixed column 33 drives the first rotating shaft 32 to rotate on the inner walls on both sides of the shell 31. The fixed column 33 drives the block 35 to move downward. The downward movement of the block 35 drives the first spring 36 to contract. The top end of the block 35 slides on the outer surface of the shell cover 5. The top end of the block 35 slides from the inner wall of the third through groove 13 opened in the water collecting pipe 2, and then slides out from the inner wall of the fourth through groove 14 opened in the shell cover 5, separating the water collecting pipe 2 from the shell cover 5, and the shell cover 5 removes the rubber check sleeve 12 for cleaning, and the filter screen 11 can prevent debris from entering.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
