Description

Technical Field

[0001] This invention relates to the technical field of drainage equipment, and in particular to a siphon rainwater structure that is easy to install. Background Technology

[0002] The emergence of siphon rainwater technology has provided assistance for building drainage. However, the installation of existing siphon rainwater systems is relatively complicated, and the amount of water accumulation needs to be controlled. Insufficient water accumulation will not trigger the siphon drainage system, which can be inconvenient in some locations where timely drainage is required.

[0003] Current siphonic rainwater drainage systems are inconvenient to relocate, causing difficulties in drainage at different locations. Therefore, there is a need to develop a smaller siphonic rainwater drainage structure to solve this problem. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides an easy-to-install siphon rainwater structure.

[0005] The present invention provides an easy-to-install siphon rainwater structure using the following technical solution: An easy-to-install siphon rainwater structure includes a water pipe, which includes several vertically arranged branch pipes and a main pipe connected to the top of the branch pipes. A drain pipe is connected to the outer wall of the main pipe, and a piston block is vertically slidably installed inside the main pipe. The water pipe is also provided with a drive mechanism for driving the piston block to move up and down.

[0006] By adopting the above technical solution, the piston block is driven up and down by the driving mechanism, which generates suction in the water pipe and creates a stable negative pressure environment in a short time. This allows rainwater to be guided to the drainage pipe for drainage. Due to the ease of operation of this structure, it can be moved to any position to accelerate local drainage. The use of negative pressure to achieve drainage significantly improves the discharge speed of rainwater. Compared with traditional gravity drainage systems, this device can discharge the same volume of rainwater in a shorter time, effectively reducing the time of water accumulation on the roof. The siphon rainwater structure of this embodiment is easy to install, and the use of negative pressure can accelerate drainage, enabling rainwater to be discharged in a short time and improving the drainage effect.

[0007] Preferably, the drive mechanism includes a pull rod that slides vertically through the top surface of the main pipe, the bottom end of the pull rod is connected to a piston block, the top end of the pull rod is connected to a pull rope, a support frame extending vertically upward is fixed on the side wall of the main pipe, the pull rope passes through the top of the support frame and extends downward, a slider is vertically slidably connected to the outer wall of the branch pipe, the pull rope is connected to the slider, a rotating rod is hinged on the slider, an L-shaped stop is fixed on the side wall of the main pipe for driving the end of the rotating rod close to the slider to move downward, a nut is installed on the top of the pull rod, a tension spring is sleeved on the pull rod, and the tension spring is connected between the nut and the top surface of the main pipe.

[0008] By employing the above technical solution, the water pipe is repeatedly pressed. Due to the obstruction of the L-shaped stop, one end of the rotating rod contacts the ground, while the other end moves downward, causing the slider to move downward along the guide rail. This, in turn, pulls the pull rope downward, causing the pull rod to move the piston block upward. Using negative pressure, water is drawn into the main pipe and then discharged through the drain pipe. When the water pipe moves upward, the tension spring elastically resets, causing the pull rod and piston block to move downward and reset. At the same time, it causes the pull rope to move upward, which in turn causes the slider to move upward, thus resetting the rotating rod. Repeated operation can accelerate the drainage process.

[0009] Preferably, a guide wheel is installed at the end of the rotating rod away from the slider.

[0010] By adopting the above technical solution, it is easier to rotate the rod after it comes into contact with the ground.

[0011] Preferably, a guide rail is vertically fixed to the outer wall of the branch pipe, the guide rail has a U-shaped cross-section, and the slider is slidably connected inside the guide rail.

[0012] By adopting the above technical solution, it is easy to effectively combine with the slider and the guide rail.

[0013] Preferably, two limiting plates are fixed to the bottom of the guide rail, and a limiting rod is installed between the two limiting plates to prevent the slider from disengaging from the guide rail.

[0014] By adopting the above technical solution, the slider can be prevented from accidentally detaching from the guide rail.

[0015] Preferably, a guide ring is installed on the top of the support frame, and the pull rope is threaded through the guide ring.

[0016] By adopting the above technical solutions, the smoothness of the rope movement process is improved.

[0017] Preferably, a top block is installed on the side of the support frame, and a groove is provided on the side wall of the top block, with the pull rope laid in the groove.

[0018] By adopting the above technical solution, it is easy to keep the pull rope in a vertical state, that is, to maintain a stable working state.

[0019] Preferably, the cross-section of the branch pipe is rectangular, a rotating plate is rotatably connected to one side of the bottom inner wall of the branch pipe, a stop block is fixed to the other side of the bottom inner wall of the branch pipe, the rotating plate is movably mounted on the top surface of the stop block, and a compression spring is provided on the bottom inner wall of the branch pipe above the rotating shaft, the compression spring elastically supporting the inner wall of the branch pipe and the top surface of the rotating plate.

[0020] By adopting the above technical solution, it is easier to create a negative pressure environment inside the water pipe and improve the siphon effect. Attached Figure Description

[0026] The following combination Figures 1-4 The present invention will be described in further detail below.

[0027] This invention discloses an easy-to-install siphon rainwater drainage structure. (Refer to...) Figures 1-4 The easy-to-install siphon rainwater structure includes a water pipe 1, which includes two vertically arranged branch pipes 10 and a main pipe 11 connected to the top of the two branch pipes 10. The cross-sections of the branch pipes 10 and the main pipe 11 are both rectangular. A drain pipe 2 is connected to the side wall of the main pipe 11, and a piston block 3 is vertically slidably installed inside the main pipe 11. The piston block 3 is driven by a drive mechanism 4 installed on the water pipe 1.

[0028] The drive mechanism 4 includes two pull rods 40 that slide vertically through the top of the main pipe section 11. The bottom end of the pull rod 40 is connected to the piston block 3. A sealing ring is provided at the connection between the pull rod 40 and the main pipe section 11. The two pull rods 40 are symmetrically arranged on the left and right sides of the top surface of the main pipe section 11. Vertically upward extending support frames 41 are fixed to the side walls on the left and right sides of the main pipe section 11. A guide ring 410 is installed on the top of the support frame 41, and a top block 411 is installed on the side of the support frame 41. A pull rope 42 is connected to the top of the pull rod 40. The pull rope 42 extends upward through the guide ring 410 and then rests downward in the groove on the surface of the top block 411.

[0029] A U-shaped guide rail 43 is vertically fixed to the outer wall of the branch pipe 10. A slider 44 is vertically slidably connected inside the guide rail 43. The bottom end of the pull rope 42 is connected to the slider 44. Two limiting plates 430 are fixed to the bottom outer wall of the guide rail 43. A limiting rod 431 is installed between the two limiting plates 430 to prevent the slider 44 from moving down and detaching from the guide rail 43. Two hinge plates 440 are fixed to the outer wall of the slider 44. A rotating rod 45 is hinged between the two hinge plates 440. A guide wheel 450 is installed at the end of the rotating rod 45 away from the slider 44.

[0030] Two L-shaped stop bars 46 are symmetrically fixed to the side wall of the main pipe 11. The horizontal part of the L-shaped stop bar 46 is fixed to the side wall of the main pipe 11, and the vertical part of the L-shaped stop bar 46 extends downward to movably abut against the rotating rod 45, so as to push the rotating rod 45 close to the end of the slider 44 and the slider 44 move downward along the guide rail 43. The upper half of the pull rod 40 is provided with external thread and a nut 47 is threaded on it. A tension spring 48 is sleeved on the pull rod 40. One end of the tension spring 48 is connected to the nut 47, and the other end of the tension spring 48 is connected to the top surface of the main pipe 11. The tension spring 48 has a tendency to pull the pull rod 40 downward.

[0031] A rotating plate 12 is rotatably connected to one side of the bottom inner wall of the branch pipe section 10. A compression spring 13 is provided above the rotating shaft where the rotating plate 12 is located. The compression spring 13 is elastically supported between the top surface of the rotating plate 12 and the inner wall of the branch pipe section 10. The compression spring 13 has an elastic tendency to drive the rotating plate 12 to rotate downward. A stop block 14 is fixedly connected to the side of the inner wall of the branch pipe section 10 away from the rotating shaft. The rotating plate 12 is movably mounted on the top surface of the stop block 14. When the piston block 3 moves upward, the rotating plate 12 flips upward, and the water flows through the branch pipe section 10 into the main pipe section 11.

[0032] The implementation principle of the easy-to-install siphon rainwater structure in this embodiment of the invention is as follows: When it is necessary to speed up drainage, the device is moved to the location where drainage is needed, and then the drain pipe 2 is pulled out and the water pipe 1 is pressed repeatedly. Due to the obstruction of the L-shaped stop bar 46, one end of the rotating rod 45 contacts the ground, while the other end moves downward and drives the slider 44 to move downward along the guide rail 43, thereby pulling the pull rope 42 downward. The pull rod 40 drives the piston block 3 to move upward, and the negative pressure is used to draw water into the main pipe 11, and then the accumulated water is discharged through the drain pipe 2.

[0033] When the water pipe 1 moves upward, the tension spring 48 elastically resets, causing the pull rod 40 and piston block 3 to move downward and reset, while simultaneously causing the pull rope 42 to move upward. The pull rope 42 then causes the slider 44 to move upward, thereby resetting the rotating rod 45. Repeated operation can speed up the drainage process. The length of the drainage pipe 2 can be adjusted or replaced with different lengths as needed on site. After the drainage work is completed, the drainage pipe 2 is wound up to reduce the space occupied by the device.

[0034] In this embodiment of the invention, the siphon rainwater structure moves up and down, and the slider 44 slides within the guide rail 43, thereby enabling the pull rod 40 to slide. The sliding of the pull rod 40 generates suction in the water pipe 1, creating a stable negative pressure environment in a short time. This allows rainwater to be guided to the drainage pipe 2 for drainage. Due to the ease of operation of this structure, it can be moved to any position to accelerate local drainage and utilize negative pressure to achieve drainage.

[0035] This negative pressure environment rapidly guides rainwater from the roof or other high places to the drainage pipe 2, achieving efficient siphon drainage and significantly improving the discharge speed of rainwater. Compared with traditional gravity drainage systems, this device can discharge the same volume of rainwater in a shorter time, effectively reducing the time of water accumulation on the roof. The siphon rainwater structure of this embodiment is easy to install, and by utilizing the negative pressure effect, it can accelerate drainage, discharge rainwater in a short time, and improve the drainage effect.

[0036] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
