DETAILED DESCRIPTION OF THE INVENTION
[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] In the embodiment, it is given by Figure 1-6 A micro-overflow rainwater drainage device for adjusting the height of the overflow water level. The present invention includes a wellbore 1, a top of the wellbore 1 is connected with an overflow cylinder 2, an inner top wall of the overflow cylinder 2 is connected with a water flow driving component 3, a top of the overflow cylinder 2 is rotatably connected with a cleaning frame 4 contacting the outside of the overflow cylinder 2, a bottom of the wellbore 1 is connected with an auxiliary release cylinder 5, an inside of the auxiliary release cylinder 5 is slidably connected with a shielding ring 6, an inner side of the shielding ring 6 is fixedly connected with a connecting frame 7, a top of the connecting frame 7 is rotatably connected with a pull rod 8 whose outside forms a transmission connection with the water flow driving component 3 and the cleaning frame 4, a bottom of the auxiliary release cylinder 5 is communicated with a drainage cylinder 9, and an outside of the drainage cylinder 9 is communicated with a drainage pipe 10.
[0036] Wherein, a plurality of overflow holes distributed in an array are formed on an outside of the overflow cylinder 2, and a bottom of the cleaning frame 4 extends below the lowermost overflow hole.
[0037] Wherein, the cleaning frame 7 is L-shaped and a side opposite to the outside of the overflow cylinder 2 is connected with a spring, and the other end of the spring is fixedly connected with a cleaning brush contacting the overflow cylinder 2.
[0038] Wherein, sealing gaskets are arranged on both an inner side and an outer side of the shielding ring 6, a top of the connecting frame 7 is connected with a filter plate, and a plurality of auxiliary drainage holes are formed in the shielding ring 6.
[0039] Wherein, the water flow driving component 3 is rotatably connected to a rotating frame 31 on an inner top wall of the overflow cylinder 2, a bottom of the rotating frame 31 is fixedly installed with a water-driven impeller 32, and an inside of the water-driven impeller 32 is fixedly installed with a connecting sleeve 33 forming a transmission connection with the pull rod 8.
[0040] When water flows downward, due to its own potential energy, it impacts the water-driven impeller 32, so that the water-driven impeller 32 can start to rotate, and then drives the pull rod 8 to start rotating.
[0041] Wherein, the pull rod 8 is square, and a bottom of the pull rod 8 is provided with a rotating disk extending into the connecting frame 7.
[0042] Wherein, a height locking component 11 is arranged between a connection part of the overflow cylinder 2 and the cleaning frame 4. The height locking component 11 includes a transmission sleeve 111 rotatably connected to the top of the overflow cylinder 2 and fixedly connected with the cleaning frame 4, and a locking pin 112 extending into its inside and locking the pull rod 8 is threadedly connected to an outside of the transmission sleeve 111.
[0043] When it is necessary to keep the pull rod 8 at a certain height, loosen the locking pin 112, then pull the pull rod 8 upward to keep it at a certain height, and then lock the locking pin 112.
[0044] Wherein, water eddy current pushing pieces are fixedly installed on an outside of the cleaning frame 4, and an anti-rust paint is coated on an outside of the water eddy current pushing pieces.
[0045] The wellbore 1 and the overflow tube 2 are connected by fasteners. A support groove and a support rod placed in the support groove are opened inside the overflow tube 2. The support rod is composed of two support sub-rods with different diameters.
[0046] When it is necessary to clean the interior, the fasteners can be removed, and then the wellbore 1 and the overflow tube 2 can be separated. At this time, the support rod can be taken out and turned upside down. At this time, the wellbore 1 can be supported by the support rod, so that the interior can be easily cleaned.
[0047] Working principle:
[0048] When rainwater accumulates, it can flow through the overflow hole and then be discharged through the overflow tube 2, the well 1 and the drainage tube 9, so that the rainwater can be discharged conveniently;
[0049] When the rainfall increases, more garbage such as leaves carried to the overflow tube 2 by the rainwater increases. At the same time, when the rainfall increases, the water flow speed increases, and a water vortex is formed at the drainage point. At this time, the water flow direction forms a certain angle with the cleaning frame 4. At the same time, after entering the overflow tube 2, the flowing water hits the water driving impeller 32. Under the action of the two forces, the cleaning frame 4 is pushed to start moving and start cleaning the external obstacles.
[0050] When the rainfall continues to increase but the rainwater has no time to be discharged, the rainwater begins to spread. At this time, the height of the pull rod 8 is adjusted by the height locking device 11, so that the connecting frame 7 connected thereto can drive the shielding ring 6 to move upward, so that the auxiliary release cylinder 5 can start to drain water, so that part of the water can be discharged through the soil gap, thereby reducing the drainage pressure.
