Description

Technical Field

[0001] The invention relates to the technical field of valves, in particular to a valve device for preventing building pipelines from being blocked by utilizing natural rainwater. Background Art

[0002] In the design of house buildings, the design of roof drainage pipes is very important. If the drainage pipe system cannot effectively divert rainwater, rainwater will easily penetrate into the room. In the long run, it is easy to damage the wall structure.

[0003] In order to achieve the drainage of precipitation, Chinese utility model patent CN2023229683519 discloses a building rainwater pipe variable diameter diversion device, which diverts rainwater before and after rainfall to prevent the drainage pipe system from being blocked. However, during the application of the above device, rainwater is prone to carry solid debris after flushing, causing the above pipe system to be blocked.

[0004] Another example is the Chinese invention patent application number CN202411073842X, which discloses a new type of prefabricated inspection well and drainage pipe system. The pipe system has high connection strength and is leak-proof. And because the shape of the pipe is elliptical, the siltation problem in the pipe can be reduced. However, branches, debris or dust carried by rainwater can still block the pipeline during a long period of flushing. Relying solely on the shape of the pipe cavity to solve the siltation problem of the pipeline system is not effective. Therefore, designing a rainwater anti-blocking valve structure that does not require human intervention is an urgent problem to be solved. Summary of the invention

[0005] The object of the present invention is to provide a valve device for preventing building pipelines from being blocked by natural rainwater. By using the valve device, solid debris can be prevented from accumulating in the pipelines, thereby preventing the roads from being blocked.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A valve device for preventing building pipelines from being blocked by natural rainwater comprises a water diversion pipe and an anti-blocking mechanism arranged at the water inlet port of the water diversion pipe; the anti-blocking mechanism comprises an outer shell, a dredging assembly and a natural rainwater driving assembly; an annular isolation baffle is arranged inside the outer shell, and a limit block is arranged at the side end of the rotating seat, the limit block is tightly pressed against the annular isolation baffle and is rotatably connected; the dredging assembly comprises a guide rod and a rotating seat; the guide rod is eccentrically arranged on the rotating seat; the rotating seat is rotatably connected to the hollow interior of the outer shell, the lower end of the rotating seat is rotatably connected to the water outlet of the outer shell, and the water diversion pipe is communicated with the water outlet of the outer shell; the natural rainwater driving assembly is transmission-connected to the limit block.

[0008] The anti-blocking mechanism is installed at the water inlet of the water pipe. The eccentrically arranged guide rod moves in the water pipe to clear the accumulated solid debris. This can prevent the pipe from being blocked by branches or soil. The power source of the guide rod is provided by natural rainwater falling. Therefore, the valve device does not need to provide an additional power source from the outside when it is used, which meets the requirements of green buildings.

[0009] Preferably, the natural rainwater driving assembly comprises a rotating wheel, an active transmission wheel, a transmission wheel, a rotating rod, a spring and an intermittent fan-shaped wheel; the rotating wheel is transmission-connected to the limit block, and the rotating wheel and the active transmission wheel are synchronously transmission-connected via the rotating rod; the active transmission wheel and the transmission wheel are meshingly transmission-connected, the active transmission wheel is provided with a fan-shaped notch, and the intermittent fan-shaped wheel is rotatably disposed in the fan-shaped notch, one end of the spring is fixed to the intermittent fan-shaped wheel, and the other end is fixed to the active transmission wheel.

[0010] Among them, the design of the natural rainwater driving component is mainly to provide intermittent power for the rotating seat to drive the guide rod to rotate.

[0011] Preferably, a rotation groove is provided on the side wall of the sector-shaped notch, and correspondingly, the intermittent sector-shaped wheel is rotatably installed in the rotation groove.

[0012] Preferably, the intermittent sector wheel and the active transmission wheel are both provided with fixed protrusions, and the two ends of the spring are respectively fixed to the two fixed protrusions.

[0013] Preferably, the natural rainwater driving assembly further comprises a water-powered wheel and a connecting rod, and the driving wheel and the water-powered wheel are fixed to each other via the connecting rod.

[0014] Preferably, a positioning convex ring is provided at the upper end of the annular isolation baffle, and correspondingly, the limit block is provided with a positioning groove adapted to the positioning convex ring.

[0015] Preferably, the unblocking component also includes a grinding piece for grinding large particles of debris; the grinding piece includes a guide plate, an upper grinding ring and a lower grinding ring; the guide plate is fixed to the side end of the guide rod, the lower grinding ring is fixed to the upper end opening of the outer shell, and the upper grinding ring is fixed to the inner end of the guide plate, and the upper grinding ring and the lower grinding ring form a gap for crushing debris.

[0016] Among them, the design of the grinding piece can grind some large particles of solid matter into small particles, so that they can be washed to the end of the pipeline with rainwater, avoiding the accumulation of solid matter in the middle of the pipeline, which will cause blockage in the middle of the pipeline and increase the difficulty of clearing it later.

[0017] Preferably, a water guide ring is provided at the lower end of the guide plate.

[0018] Preferably, the upper grinding ring and the lower grinding ring are both provided with through holes adapted to the movement path of the guide rod, and the inner ring side wall of the lower grinding ring is in close contact with the upper edge of the rotating seat.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By installing a dredging component at the outlet of the water pipe, it is possible to prevent precipitation from bringing debris from the high-rise flat roof into the pipe, causing the pipe to be blocked by solid objects. This will cause rainwater to penetrate the inner wall and destroy the stability of the wall structure.

[0021] 2. The anti-blocking mechanism is not powered by electricity and has no external power supply. The power comes from natural rainwater, which not only achieves the green building goal of saving energy, but also avoids rainwater erosion that causes damage to the circuit system, thereby affecting the anti-blocking effect.

[0022] 3. The anti-blocking mechanism has a simple structure and can be directly installed at the water inlet of the water pipe on the flat roof. It does not affect the drainage effect while preventing blockage and leakage. It can be used in ground floor, middle floor or high-rise buildings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0030] like Figure 1-Figure 5 As shown, a valve device for preventing building pipelines from being blocked by natural rainwater comprises a water diversion pipe 15 and an anti-blocking mechanism arranged at a water inlet port of the water diversion pipe 15;

[0031] The anti-clogging mechanism includes an outer shell 7, a dredging component and a natural rainwater driving component; an annular isolation baffle 16 is provided inside the outer shell 7, and a limit block 8 is provided at the side end of the rotating seat 14, and the limit block 8 is tightly pressed against the annular isolation baffle 16 and is rotatably connected; the dredging component includes a guide rod 1 and a rotating seat 14; the guide rod 1 is eccentrically arranged on the rotating seat 14; the rotating seat 14 is rotatably connected to the hollow interior of the outer shell 7, the lower end of the rotating seat 14 is rotatably connected to the water outlet of the outer shell 7, and the water diversion pipe 15 is connected to the water outlet of the outer shell 7; the natural rainwater driving component is transmission-connected to the limit block 8.

[0032] See also Figure 3 The connection relationship and working principle of the internal components of the dredging component are as follows:

[0033] When the rotating seat 14 is driven to rotate by the driving member, the guide rod 1 eccentrically connected thereto will also rotate eccentrically. When the guide rod 1 rotates eccentrically, it will stir the branches, leaves, dust, etc. accumulated in the water diversion pipe 15. As a result, when the precipitation flows in the water diversion pipe 15, the debris can be washed to the water outlet of the pipe, achieving an anti-blocking effect.

[0034] See also Figure 1 and Figure 3 The natural rainwater driving assembly includes a rotating wheel 11, an active transmission wheel 9, a transmission wheel 12, a rotating rod 10, a spring 19, an intermittent fan wheel 18, a water power wheel 13 and a connecting rod. The rotating wheel 11 is connected to the limit block 8 by transmission, and the rotating wheel 11 is connected to the active transmission wheel 9 by synchronous transmission through the rotating rod 10; the active transmission wheel 9 is connected to the transmission wheel 12 by meshing transmission, the active transmission wheel 9 is provided with a fan-shaped notch, and the intermittent fan wheel 18 is rotatably arranged in the fan-shaped notch, one end of the spring 19 is fixed to the intermittent fan wheel 18, and the other end is fixed to the active transmission wheel 9.

[0035] The side wall of the sector-shaped notch is provided with a rotation groove, and accordingly, the intermittent sector wheel 18 is rotatably installed in the rotation groove. The intermittent sector wheel 18 and the active transmission wheel 9 are both provided with fixed protrusions, and the two ends of the spring 19 are respectively fixed to the two fixed protrusions. The transmission wheel 12 and the hydrodynamic wheel 13 are fixed by a connecting rod.

[0036] See also Figure 3 , the connection relationship and working principle of the natural rainwater driven components are as follows:

[0037] like Figure 4 As shown, when the water flow flushes the hydrodynamic wheel 13, it will cause it to rotate. Since the transmission wheel 12 and the hydrodynamic wheel 13 rotate synchronously, the hydrodynamic wheel 13 will also rotate. Under the meshing transmission with the active transmission wheel 9, the hydrodynamic wheel 13 will drive the rotating wheel 11 to rotate, thereby driving the rotating seat 14 to rotate, and then driving the guide rod 1 to rotate eccentrically to clear the solid debris in the pipeline.

[0038] See also Figure 1 The working principle and purpose of the intermittent transmission of the transmission wheel 12 and the active transmission wheel 9 are:

[0039] The purpose of this setting is: since part of the water flow enters the outer shell 7 through the top of the guide plate 2, and the guide plate 2 is fixedly connected to the upper end of the guide rod 1. Therefore, when the guide rod 1 rotates, it will drive the guide plate 2 to rotate. When the guide plate 2 rotates, it is actually a way of throwing water away, and the precipitation enters little or almost no inside of the outer shell 7. Therefore, at this time, by intermittently driving the guide rod 1, it is also helpful to control the water flow to slowly enter the inside of the outer shell 7.

[0040] The principle of this arrangement is that when the transmission wheel 12 is meshed with the active transmission wheel 9, it is in a state of driving the active transmission wheel 9 to rotate. When the transmission wheel 12 rotates to mesh with the intermittent sector wheel 18, it does not drive the intermittent sector wheel 18 to rotate, and there is no relative rotation between the two. Instead, it drives the intermittent sector wheel 18 to rotate along the rotation groove to the other side of the sector notch of the active transmission wheel 9 until it meshes with the active transmission wheel 9 again, at which time the active transmission wheel 9 is driven to rotate. When the intermittent sector wheel 18 is not in contact with the transmission wheel, due to the presence of the spring 19, the intermittent sector wheel 18 will reset again, forming a motion cycle.

[0041] like Figure 5As shown, the dredging assembly also includes a grinding piece for grinding large particles of debris. The grinding piece includes a guide plate 2, an upper grinding ring 4 and a lower grinding ring 5. The guide plate 2 is fixed to the side end of the guide rod 1, the lower grinding ring 5 is fixed to the upper end opening of the outer shell 7, the upper grinding ring 4 is fixed to the inner side end of the guide plate 2, and the upper grinding ring 4 and the lower grinding ring 5 form a gap for crushing debris. The upper grinding ring 4 and the lower grinding ring 5 are both provided with through holes adapted to the movement path of the guide rod 1, and the inner ring side wall of the lower grinding ring 5 is in close contact with the upper edge of the rotating seat 14. A water diversion ring 6 is provided at the lower end of the guide plate 2.

[0042] See also Figure 3 , the connection relationship and working principle of the components in the grinding piece are as follows:

[0043] During the eccentric rotation of the guide rod 1, the upper grinding ring 4 and the lower grinding ring 5 are brought into frictional contact, so that the solid particles falling into the inner part can be crushed into small particles until they are washed into the pipeline by precipitation. Since the upper grinding ring 4 also moves eccentrically, only one side between the upper grinding ring 4 and the lower grinding ring 5 can always be in contact and ground, and a certain amount of space is reserved for the rest of the solid debris, and the solid debris will be ground when the distance between the upper grinding ring 4 and the lower grinding ring 5 becomes smaller. Example 2

[0044] like Figure 5 As shown, this embodiment provides a schematic diagram of an application scenario. For example, when installing the pipeline device, it can be installed at the intersection of a flat roof floor with a lower potential. Then the water flow can enter along the pipeline until it is discharged into the underground water pipe network. Example 3

[0045] This embodiment explains the direction of precipitation flow.

[0046] Among them, the parts with water holes are (with Figure 4 For example): guide plate 2, upper grinding ring 4, lower grinding ring 5, upper side of outer shell 7, upper and lower sides of annular isolation baffle 16.

[0047] The direction of water flow Figure 4 As shown, precipitation can enter from the top of the guide plate 2 or the side end of the outer shell 7. Solid debris can enter from the guide plate 2 between the upper grinding ring 4 and the lower grinding ring 5, and after being crushed, it can fall into the annular isolation baffle 16 with the rainwater, and flow to the lower end of the outer shell 7 through the through holes on the lower side of the annular isolation baffle 16. When the water flows out from the lower side of the annular isolation baffle 16, it will flush the hydrodynamic wheel 13, causing it to rotate, thereby driving the rotating seat 14 to drive the guide rod 1 to rotate eccentrically.
