Description

Technical Field

[0001] The present application relates to the technical field of municipal drainage, and in particular to a throttling buffer type water outlet. Background Art

[0002] The end of a municipal stormwater drainage pipe is often located near a river or lake. During rainy seasons, the water discharged from the stormwater drainage pipe impacts the river or lake, generating a vortex similar to a waterfall underwater.

[0003] This vortex is very harmful to the organisms near the river. It is difficult to escape once caught in it, which is not conducive to the protection of the ecology. In response to the above-mentioned related technologies, the applicant proposed an outlet at the end of the drainage pipe that can buffer the drainage impact force. Utility Model Content

[0004] In order to buffer the drainage impact force at the end of the drainage pipe, the present application provides a throttling buffering water outlet.

[0005] The throttling buffer type water outlet provided in the present application adopts the following technical solution:

[0006] A throttling buffer type water outlet comprises a drain pipe, the rear end of which is rotatably connected to a water dispersion structure, the aperture of which is smaller than that of the drain pipe, and a groove is provided on the side wall of the water dispersion structure, and the groove extends toward the rear end of the drain pipe; a diffuser is lifted and connected to one side of the drain pipe near the water dispersion structure, the diffuser is lifted and connected between the upper end of the drain pipe and the axis of the drain pipe, and a driving structure for driving the diffuser to descend is provided on the water dispersion structure.

[0007] By adopting the above technical solution, the drainage pipe uses the water dispersion structure at the front end to diffuse and dissipate the water column, so that the impact point is no longer concentrated. At the same time, a diffuser for enhancing the diffusion effect is also provided in the pipe. When the water flow is large, the diffuser adds force dissipation to enhance the working effect of the effective structure, thereby better reducing the impact of the water flow.

[0008] Preferably, the water-dispersing structure includes a rotating ring and water-dispersing claws. The rotating ring is sleeved and rotatably connected to the rear end of the drain pipe, and the inner diameter of the rotating ring is flush with the inner diameter of the rear end of the drain pipe; the water-dispersing claws are fixed to the rotating ring at intervals, extend toward a side away from the drain pipe and shrink toward the axial direction of the drain pipe, and the water-dispersing claws are inclined toward the needle side at the same time.

[0009] By adopting the above technical solution, the water dispersion claws can act on the water column without affecting the flow of the pipeline, so that the water column is transformed into a scattered state, thereby avoiding the water column from being concentrated at one point.

[0010] Preferably, the water-spreading structure further comprises an expansion groove, which is arranged on the water-spreading claw bracket, and the circumferential width of the expansion groove gradually increases with the contraction between the water-spreading claws.

[0011] Preferably, the diffuser is provided with a lifting structure, which includes a lifting rod, a supporting spring and a transverse abutment bracket. The lifting rod is lifted and connected to the upper end of the drain pipe and is passed through the inner and outer sides of the drain pipe, and the diffuser is fixed to the lower end of the lifting rod; the supporting spring extends vertically and can be bent left and right along the drain pipe, and the top end of the supporting spring is fixed to the top end of the lifting rod, and the bottom end is fixed to the outer wall of the drain pipe; the transverse abutment bracket is transversely slidably connected to the drain pipe, and the transverse abutment bracket abuts one side of the support spring.

[0012] By adopting the above technical solution, the lifting structure can not only drive the diffuser to rise and fall, but also can mutually drive the rotating ring, so that the lifting and falling of the structure can be achieved through a simple structure, which is low-cost and highly practical.

[0013] Preferably, the driving structure includes a driving wheel and an abutment roller, the driving wheel is rotatably connected to the outer side wall of the drain pipe, one end of the driving wheel abuts and rotatably connected to the outer side of the rotating ring, and the other end abuts and rotatably connected to the transverse abutment bracket; the abutment roller is rotatably connected to the transverse abutment bracket, and the abutment roller abuts and rotatably connected to the middle part of the side wall of the supporting spring.

[0014] Preferably, the diffuser is circularly arranged and is hemispherically arranged toward the front end of the drain pipe, and the density of the diffuser is consistent with that of water.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. The drainage pipe uses the water dispersion structure at the front end to diffuse and dissipate the water column, so that the impact point is no longer concentrated. At the same time, a diffuser is also provided in the pipe to enhance the diffusion effect. When the water flow is large, the diffuser adds force dissipation to enhance the working effect of the effective structure, thereby better reducing the impact of the water flow;

[0017] 2. The water dispersion claws can transform the water column into a scattered state without affecting the flow of the pipeline, thus avoiding the water column from being concentrated in one point;

[0018] 3. The lifting structure drives the diffuser to rise and fall, and can also drive the rotating ring to rise and fall. The lifting and falling of the structure can be achieved through a simple structure, which is low-cost and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The present application embodiment discloses a throttling buffer type water outlet, referring to Figure 1 , 2 , including a drain pipe 1, the rear end of the drain pipe 1 is rotatably connected with a water dispersion structure 2, the water dispersion structure 2 includes an expansion groove 23, a rotating collar 21 and a water dispersion claw 22, the rotating collar 21 is sleeved and rotatably connected to the rear end of the drain pipe 1, and the inner diameter of the rotating collar 21 is flush with the inner diameter of the rear end of the drain pipe 1; the water dispersion claw 22 is fixed to the rotating collar 21 at intervals, and extends toward a side away from the drain pipe 1 and shrinks toward the axial direction of the drain pipe 1, and the water dispersion claw 22 is inclined toward the needle side at the same time. When the water flow hits the water dispersion claw 22, the inner and outer sides of the water column convect with each other, the water flow becomes scattered, the water column becomes dispersed, and the impact force of the water column becomes smaller.

[0025] Reference Figure 1 , 2 The expansion groove 23 is opened on the bracket of the water-spreading claw 22, so that part of the water flow is discharged through the expansion groove 23, reducing the impact force of the water column; the circumferential width of the expansion groove 23 gradually increases with the contraction between the water-spreading claws 22, so that the water flow can be discharged from the expansion groove 23 while the water column of the water-spreading claws 22 is reduced, and the drainage volume of the drain pipe 1 is not affected; at the same time, the expansion groove 23 also provides sufficient air for the water-spreading claws 22, and the water column inhales air while colliding with the water-spreading claws 22, thereby achieving the effect of atomizing the water column.

[0026] Reference Figure 1 , 2 At the same time, since the water-spreading claw 22 is tilted toward one side, when the water-spreading claw 22 is impacted by a water column with a large flow rate, it drives the rotating collar 21, and the rotating collar 21 drives the diffuser 3 to further absorb the impact force of the water column.

[0027] Reference Figure 1 , 3 The diffuser 3 is connected to the inner side of the drain pipe 1 through a lifting structure 5. The lifting structure 5 includes a lifting rod 51, a supporting spring 52 and a transverse abutment bracket 53. The lifting rod 51 is lifted and connected to the upper end of the drain pipe 1 and is passed through the inner and outer sides of the drain pipe 1. The diffuser 3 is fixed to the lower end of the lifting rod 51. The diffuser 3 is circularly arranged and is hemispherically arranged toward the front end of the drain pipe 1. The density of the diffuser 3 is consistent with that of water to prevent it from floating up due to buoyancy. When the lifting rod 51 slides to the bottom, the diffuser 3 is arranged corresponding to the center of the drain pipe 1.

[0028] Reference Figure 1 , 3 The support spring 52 extends vertically and can be bent left and right along the drain pipe 1, and the top end of the support spring 52 is fixed to the top end of the lifting rod 51, and the bottom end is fixed to the outer wall of the drain pipe 1; the transverse abutment bracket 53 is connected to the drain pipe 1 in a transverse sliding manner, and the transverse abutment bracket 53 abuts against one side of the support spring 52, and the transverse abutment bracket 53 is driven by the driving structure 4 connected to the rotating ring 21.

[0029] Reference Figure 1 , 3 The driving structure 4 includes a driving wheel 41 and an abutting roller 42. The driving wheel 41 is rotatably connected to the outer wall of the drain pipe 1. One end of the driving wheel 41 abuts and is rotatably connected to the outer side of the rotating ring 21, and the other end abuts and is rotatably connected to the transverse abutting bracket 53; the abutting roller 42 is rotatably connected to the transverse abutting bracket 53, and the abutting roller 42 abuts and is rotatably connected to the middle part of the side wall of the supporting spring leaf 52 to reduce the abutting friction.

[0030] The working process of the present application is as follows: when the water flow in the drainage pipe 1 is large, the water flow drives the rotating ring 21 to rotate by hitting the water-spreading claws 22, and the rotating rotating ring 21 drives the lateral abutment bracket 53 to move laterally, and then the abutment roller 42 abuts against the supporting spring 52 to bend, and the lifting rod 51 loses the support of the supporting spring 52 and thus descends. After descending, the diffuser 3 diffuses the water column, so that more water flow hits the water-spreading claws 22, thereby dispersing the impact force of the water column.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
