Description

Technical Field

[0001] The present application relates to the technical field of rainwater abandonment, and in particular to a rainwater well type automatic abandonment device. Background Art

[0002] During rainfall, affected by the underlying surface, the rainwater that has just been collected, namely the initial runoff, contains more pollutants and has poor water quality. As the rainfall continues, the early rainwater washes away the debris on the underlying surface, and the mid- and late-stage rainwater is relatively clean and has better water quality. To collect and treat the rainwater for reuse, the focus should naturally be on the clean rainwater in the mid- and late-stages, and the dirtier initial rainwater should be separated from the total amount of rainwater to be treated and utilized. This separation of the initial rainwater does not affect the treatment process of the collected rainwater, and is called initial rainwater abandonment.

[0003] The current flow abandonment devices generally include three types: automatic flow abandonment devices, infiltration flow abandonment devices and flow abandonment pools. Automatic flow abandonment devices use electric valve devices, which need to be connected to electricity, are costly, complicated to make, and have high operating costs. Their stability is not as good as that of pure mechanical devices that do not use electricity. Infiltration flow abandonment devices are only suitable for rainwater wells and rainwater outlets installed underground. Whether the rainwater can be infiltrated is restricted by many factors. The flow abandonment pool requires the construction of a separate pool with a large area. It is only suitable for underground installation, with a large amount of engineering and complicated methods. Summary of the invention

[0004] The main purpose of the present application is to provide a rainwater well type automatic flow abandonment device to solve the problems of high operating cost and poor stability of the electrically driven flow abandonment device in the related art.

[0005] In order to achieve the above-mentioned purpose, the present application provides a rainwater well type automatic flow abandonment device, including a rainwater well, a rainwater pipe, a collection pipe and a flow abandonment pipe.

[0006] The rainwater pipe is connected to the side of the rainwater well, the collecting pipe is connected to the side of the rainwater well, the discarded flow pipe is connected to the side of the rainwater well, the height of the discarded flow pipe is smaller than the height of the rainwater pipe, the height of the discarded flow pipe is smaller than the height of the collecting pipe, a support shaft is installed inside the discarded flow pipe, a baffle is rotatably installed on the outer wall of the support shaft, and a float is installed on one side of the baffle.

[0007] In one embodiment of the present invention, a stopper cooperating with the stopper is installed inside the waste flow pipe.

[0008] In one embodiment of the present invention, a bearing matched with the baffle is installed on the outer wall of the support shaft, the inner ring of the bearing is connected to the support shaft, and the outer ring of the bearing is connected to the baffle.

[0009] In an embodiment of the present invention, a through hole cooperating with the support shaft is opened in the middle of the baffle.

[0010] In one embodiment of the present invention, the cross section of the baffle is circular, and the diameter of the baffle matches the inner diameter of the discarding pipe.

[0011] In an embodiment of the present invention, a water-permeable hole is formed on a side of the baffle away from the floating body.

[0012] In one embodiment of the present invention, a counterweight is provided on the side of the baffle adjacent to the water permeable hole.

[0013] In one embodiment of the present invention, a manhole cover is installed on the upper part of the rainwater well, and a support rod cooperating with the floating body is installed inside the rainwater well.

[0014] In one embodiment of the present invention, the collecting pipe is arranged on a side of the rainwater well away from the rainwater pipe.

[0015] In one embodiment of the present invention, the height of the collecting pipe is not higher than the height of the rainwater pipe. In the embodiment of the present application, a rainwater well type automatic flow abandonment device is provided. When in use, rainwater flows into the interior of the rainwater well through the wellhead and the rainwater pipe of the rainwater well. In the initial stage of rain, the total amount of rainwater is small, and the rainwater is discharged through the flow abandonment pipe; in the middle and later stages of rainwater, the amount of rainwater collected in the rainwater well gradually increases. Under the action of the buoyancy of rainwater, the float is pushed up, and then the baffle is rotated, and the water level in the rainwater well continues to rise until the baffle is in a vertical state as a whole, completely blocking the flow abandonment pipe mouth, and no more flow abandonment; so that the rainwater stays in the rainwater well, and the water level of the rainwater well continues to rise. When the water level rises to the collection pipe position, the clean rainwater is discharged through the collection pipe; the initial rainwater abandonment is simply achieved, and the overall pure mechanical structure is adopted, with low operating costs and high stability of abandoned rainwater.

[0029] Example 1

[0030] See also Figure 1-5 The present application provides a rainwater well type automatic flow abandonment device, comprising a rainwater well 100, a rainwater pipe 200, a collection pipe 300 and a flow abandonment pipe 400. A manhole cover 110 is installed on the upper part of the rainwater well 100. The manhole cover 110 is used to protect the rainwater well 100 to prevent people from falling into the rainwater well 100 and causing injuries. Figure 1 The rainwater pipe 200 is connected to the side of the rainwater well 100 , and is used to guide the collected rainwater into the interior of the rainwater well 100 .

[0031] See also Figure 1 The collecting pipe 300 is connected to the side of the rainwater well 100. When specifically set, the collecting pipe 300 is set on the side of the rainwater well 100 away from the rainwater pipe 200, so that the distance between the collecting pipe 300 and the rainwater pipe 200 is relatively large, preventing the rainwater from flowing out of the rainwater pipe 200 and directly entering the collecting pipe 300. The height of the collecting pipe 300 is not higher than the height of the rainwater pipe 200. The collecting pipe 300 is used to drain clean rainwater to facilitate the subsequent recycling of rainwater.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The discarded flow pipe 400 is connected to the side of the rainwater well 100, the height of the discarded flow pipe 400 is less than the height of the rainwater pipe 200, the height of the discarded flow pipe 400 is less than the height of the rainwater pipe 200 and the collection pipe 300, the height of the discarded flow pipe 400 is less than the height of the collection pipe 300, the height of the discarded flow pipe 400 is less than the height of the rainwater pipe 200 and the collection pipe 300, which is convenient for the initial discard of rainwater. A support shaft 410 is installed inside the discarded flow pipe 400, and the support shaft 410 is installed on the inner wall of the discarded flow pipe 400. A baffle 420 is rotatably installed on the outer wall of the support shaft 410. When specifically set, A block 440 cooperating with the baffle 420 is installed inside the abandoned flow pipe 400. The block 440 is used to block the baffle 420 when the baffle 420 is erected to prevent the baffle 420 from continuing to rotate and affecting the blocking of the abandoned flow pipe 400. The cross-section of the baffle 420 is circular, and the diameter of the baffle 420 matches the inner diameter of the abandoned flow pipe 400. A float 430 is installed on one side of the baffle 420, and a support rod 120 cooperating with the float 430 is installed inside the rainwater well 100 for supporting the float 430 so that the baffle 420 is in a stable state after initialization and resetting.

[0033] In this embodiment, a bearing 450 that cooperates with the baffle 420 is installed on the outer wall of the support shaft 410, the inner ring of the bearing 450 is connected to the support shaft 410, and the outer ring of the bearing 450 is connected to the baffle 420. The baffle 420 is installed using the bearing 450, which can effectively realize the rotation of the baffle 420. A through hole 421 that cooperates with the support shaft 410 is opened in the middle of the baffle 420, and the through hole 421 facilitates the support shaft 410 to pass through the middle of the baffle 420.

[0034] In this embodiment, a water hole 422 is opened on the side of the baffle 420 away from the float 430. The water hole 422 is used to discharge the rainwater accumulated in the lower part of the rainwater well 100 after the rain stops, thereby resetting the baffle 420. A counterweight block 423 is provided on the side of the baffle 420 adjacent to the water hole 422. The counterweight block 423 is used for counterweighting to ensure that the baffle 420 is balanced inside the waste flow pipe 400 when not in use.

[0035] See also Figure 1 , Figure 2 and Figure 3Specifically, the working principle of the rainwater well type automatic flow abandonment device is as follows: when in use, rainwater flows into the interior of the rainwater well 100 through the wellhead of the rainwater well 100 and the rainwater pipe 200. In the initial stage of rain, the total amount of rainwater is small, and the rainwater is discharged through the flow abandonment pipe 400; in the middle and later stages of rainwater, the amount of rainwater collected in the rainwater well 100 gradually increases. Under the action of the buoyancy of rainwater, the float 430 is pushed up, thereby causing the baffle 420 to rotate around the support shaft 410, and the water level in the rainwater well 100 continues to rise until the baffle 420 is in a vertical state as a whole, which is conducive to the flow abandonment pipe 400. The rainwater is blocked and no more flow is abandoned; the rainwater stays in the rainwater well 100, and the water level of the rainwater well 100 continues to rise. When the water level rises to the position of the collecting pipe 300, the clean rainwater is discharged through the collecting pipe 300; after the rain stops, the water inside the rainwater well 100 is first discharged through the abandonment pipe 400, and then the remaining water slowly flows out through the water permeable hole 422, thereby realizing the reset of the baffle 420, and the residual water in the rainwater well 100 is discharged through the water permeable hole 422, so as to simply realize the abandonment of the initial rainwater. The overall structure adopts a purely mechanical structure, with low operating cost and high stability of the abandonment.

[0036] It should be noted that the baffle 420 can be made of stainless steel plates, carbon steel plates, aluminum alloy plates, plastic sheets and other plates; the float 430 can be made of lightweight floatable materials such as cavity plastics, solid hard sponges and polyurethane blocks.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
