Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal drainage, and in particular to an overflow treatment device based on a rainwater pipe network outlet. Background Art
[0002] The rainwater pipe network is an important part of the urban drainage system. It is responsible for collecting and treating rainwater runoff, including road rainwater, roof rainwater, surface runoff and underground seepage water. Through the rainwater pipe network, rainwater can be transported to sewage treatment plants or natural water bodies for further sewage treatment or natural purification.
[0003] However, the existing technology still has many defects in actual use. For example, rainwater flowing through the outlet of the rainwater pipe network usually flows at the normal flow rate of rainwater, and relies on the flow of rainwater itself, resulting in a slower flow rate of rainwater, which makes it impossible for rainwater inside the rainwater pipe network to be discharged in time, resulting in excessive accumulation of rainwater on the road surface, thereby causing urban waterlogging. Therefore, it is necessary to increase the flow rate of rainwater flowing through the outlet of the rainwater pipe network. Utility Model Content
[0004] The purpose of the utility model is to provide an overflow processing device based on a rainwater pipe network outlet, so as to solve the problem that in the prior art, rainwater overflowing the rainwater pipe network outlet usually flows along the normal flow velocity of rainwater, and relies on the flow of rainwater itself, resulting in a slow flow velocity of rainwater, so that rainwater inside the rainwater pipe network cannot be discharged in time, resulting in excessive accumulation of rainwater on the road surface, thereby causing urban waterlogging. Therefore, it is necessary to increase the flow velocity of rainwater overflowing the rainwater pipe network outlet.
[0005] The utility model provides the following technical solution: a flow treatment device based on a rainwater pipe network outlet, comprising an inlet pipe, a sedimentation tank fixedly installed at the bottom end of the inlet pipe, an outlet pipe penetratingly connected to one side of the outer wall of the inlet pipe, a valve mechanism arranged inside the outlet pipe, a connecting elbow penetratingly connected to the side of the outlet pipe away from the inlet pipe, a drainage pipe penetratingly connected to the bottom end of the connecting elbow, and a drainage mechanism arranged inside the drainage pipe.
[0006] As a preferred embodiment of the above technical solution, grooves are provided on both sides of the inner wall of the water inlet pipe, and two groups of protrusions are slidably installed inside the grooves. The bottom ends of the two groups of protrusions are fixedly connected to filter plates, and handles are fixedly installed on both sides of the top of the filter plate. Larger impurities in rainwater are filtered by the filter plate, and the filtered impurities accumulate on the surface of the filter plate. When it is necessary to clean the impurities on the surface of the filter plate, the operator holds the handle to drive the protrusion to slide inside the groove, and the sliding protrusion drives the filter plate to slide out of the water inlet pipe, which is convenient for the operator to clean the impurities accumulated on the surface of the filter plate.
[0007] As a preferred embodiment of the above technical solution, a buffer block is fixedly installed on one side of the sedimentation tank close to the outlet pipe, and the top of the buffer block is sloped. The slope of the buffer block is used to buffer the sand and gravel particles in the rainwater. The buffered sand and gravel particles slide through the slope of the buffer block to the inside of the sedimentation tank for sedimentation.
[0008] As a preferred embodiment of the above technical solution, the valve mechanism includes a mounting sleeve and a motor, the mounting sleeve is installed on the inner wall of the water outlet pipe, a rotating rod is rotatably installed on the inner side of the mounting sleeve, and a valve plate is fixedly sleeved on the outer side of the rotating rod. The valve plate is driven to rotate inside the mounting sleeve by the rotation of the rotating rod, and the rotating valve plate facilitates opening and closing of the conveying channel inside the water outlet pipe.
[0009] As a preferred embodiment of the above technical solution, a motor is installed on the outer wall of the water outlet pipe through a mounting frame, and the output end of the motor is fixedly connected to one end of the rotating rod through a shaft rod. When the motor is powered on, the rotating rod is driven to rotate through the shaft rod.
[0010] As a preferred embodiment of the above technical solution, the drainage mechanism includes a mounting rod and a first sleeve. The mounting rod is installed inside the drainage pipe through a mounting frame. The surface of the mounting rod is rotatably sleeved with a first sleeve. Active fan blades are equidistantly installed on the surface of the first sleeve. Rainwater inside the connecting elbow flows into the drainage pipe through a hanging pipe. At the same time, the impact force brought by the rainwater inside the connecting elbow impacts the first sleeve. Under the action of the impact force of the rainwater, the first sleeve and the active fan blades are driven to rotate on the surface of the mounting rod.
[0011] As a preferred embodiment of the above technical solution, one end of the first sleeve is fixedly connected to a connecting rod, and the end of the connecting rod away from the first sleeve is fixedly connected to a second sleeve. The connecting rod and the second sleeve are also rotatably sleeved on the surface of the mounting rod, and driven fan blades are equidistantly installed on the surface of the second sleeve. The rotating first sleeve and the active fan blades drive the second sleeve to rotate through the connecting rod, and the rotating second sleeve drives the driven fan blades to rotate rapidly on the surface of the mounting rod. The rapid rotation of the driven fan blades accelerates the flow rate of rainwater inside the drainage pipe.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model reduces the cross-sectional area of rainwater because the diameter of the connecting elbow is smaller than the diameter of the outlet pipe, thereby increasing the flow rate of rainwater. At the same time, the rainwater with increased flow rate generates impact force through the drooping pipe of the connecting elbow. The rainwater with impact force flows into the interior of the drainage pipe through the output end of the connecting elbow and impacts the first shaft sleeve at the same time. Under the action of the impact force of rainwater, the first shaft sleeve and the active fan blade are driven to rotate on the surface of the mounting rod. The rotating first shaft sleeve and the active fan blade drive the second shaft sleeve to rotate through the connecting rod. The rotating second shaft sleeve The driven fan blades are driven to rotate rapidly on the surface of the mounting rod, and the rapid rotation of the driven fan blades accelerates the flow rate of rainwater inside the drainage pipe, so that the rainwater with the accelerated flow rate can be quickly discharged through the output end of the drainage pipe, thereby realizing the function of increasing the flow rate of rainwater flowing through the rainwater pipe network outlet, and solving the problem that the rainwater inside the rainwater pipe network cannot be discharged in time due to the slow flow rate of rainwater flowing through the rainwater pipe network outlet, thereby avoiding the problem of excessive accumulation of rainwater on the road surface causing urban waterlogging, and ensuring the efficiency of rainwater treatment at the rainwater pipe network outlet.

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a flow treatment device based on the outlet of a rainwater pipe network, comprising an inlet pipe 1, a sedimentation tank 3 is fixedly installed at the bottom end of the inlet pipe 1, a water outlet pipe 4 is connected to one side of the outer wall of the inlet pipe 1, a valve mechanism 5 is arranged inside the water outlet pipe 4, the valve mechanism 5 comprises a mounting sleeve 501 and a motor 504, the mounting sleeve 501 is mounted on the inner wall of the water outlet pipe 4, a rotating rod 502 is rotatably installed on the inner side of the mounting sleeve 501, a valve plate 503 is fixedly sleeved on the outer side of the rotating rod 502, and the water outlet pipe 4 is connected to the outlet pipe 4. A connecting elbow 6 is connected through the side away from the water inlet pipe 1, and a motor 504 is installed on the outer wall of the water outlet pipe 4 through a mounting frame. The output end of the motor 504 is fixedly connected to one end of the rotating rod 502 through an axle rod. When the motor 504 is powered on, the rotating rod 502 is driven to rotate on the inner side of the mounting sleeve 501. The rotating rotating rod 502 drives the valve plate 503 to rotate, and the rotating valve plate 503 opens the conveying channel. The rainwater after filtration and sedimentation flows into the interior of the connecting elbow 6 through the conveying channel opened by the valve plate 503 through the water outlet pipe 4.
[0022] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 5As shown, the bottom end of the connecting elbow 6 is connected with a drainage pipe 7, and a drainage mechanism 8 is arranged inside the drainage pipe 7. The drainage mechanism 8 includes a mounting rod 801 and a first sleeve 802. The mounting rod 801 is installed inside the drainage pipe 7 through a mounting frame. The surface of the mounting rod 801 is rotatably sleeved with the first sleeve 802. The outer wall of the mounting rod 801 is located outside the first sleeve 802 and the second sleeve 805 and is fixedly installed with a hoop for limiting the first sleeve 802 and the second sleeve 805 to prevent the first sleeve 802 and the second sleeve 805 from sliding. Active fan blades 803 are equidistantly installed on the surface of the first sleeve 802. One end of the first sleeve 802 is fixedly connected to a connecting rod 804, and the end of the connecting rod 804 away from the first sleeve 802 is fixedly connected to the second sleeve 805. The connecting rod 804 and the second sleeve 805 also rotate. The surface of the second sleeve 805 connected to the mounting rod 801 is equidistantly provided with driven blades 806. The rainwater with increased flow rate generates impact force through the drooping pipe connected to the elbow 6. The rainwater with impact force flows into the interior of the drainage pipe 7 through the output end of the connecting elbow 6 and simultaneously impacts the first sleeve 802. Under the action of the impact force of the rainwater, the first sleeve 802 and the active blades 803 are driven to rotate on the surface of the mounting rod 801. The rotating first sleeve 802 and the active blades 803 drive the second sleeve 805 to rotate through the connecting rod 804. The rotating second sleeve 805 drives the driven blades 806 to rotate rapidly on the surface of the mounting rod 801. The rapid rotation of the driven blades 806 accelerates the flow rate of the rainwater inside the drainage pipe 7, so that the rainwater with accelerated flow rate can be quickly discharged through the output end of the drainage pipe 7.
[0023] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, grooves 101 are provided on both sides of the inner wall of the water inlet pipe 1, and protrusions 201 are slidably installed inside the two groups of grooves 101. The bottom ends of the two groups of protrusions 201 are fixedly connected to filter plates 2, and handles 202 are fixedly installed on both sides of the top of the filter plate 2. The larger impurities in rainwater are filtered through the filter plate 2, and the filtered impurities are accumulated on the surface of the filter plate 2. When it is necessary to clean the impurities on the surface of the filter plate 2, the operator holds the handle 202 to drive the protrusion 201 to slide inside the groove 101, and the sliding protrusion 201 drives the filter plate 2 to slide out of the water inlet pipe 1, so that the operator can clean the impurities accumulated on the surface of the filter plate 2.
[0024] As an implementation method in this embodiment, Figure 1 and Figure 2As shown, a buffer block 301 is fixedly installed on one side of the sedimentation tank 3 near the outlet pipe 4. The top of the buffer block 301 is sloped. The slope of the buffer block 301 is used to buffer the sand and gravel particles in the rainwater. The buffered sand and gravel particles slide through the slope of the buffer block 301 to the inside of the sedimentation tank 3 for sedimentation, which facilitates the buffering and sedimentation of the sand and gravel particles in the rainwater.
[0025] Working principle: larger impurities in rainwater are filtered through the filter plate 2, and the rainwater after preliminary filtration by the filter plate 2 flows into the interior of the water inlet pipe 1, and the sand and gravel particles in the rainwater are buffered by the slope of the buffer block 301. The buffered sand and gravel particles slide through the slope of the buffer block 301 to the interior of the sedimentation tank 3 for sedimentation, and the motor 504 is powered on to drive the rotating rod 502 to rotate on the inner side of the mounting sleeve 501, and the rotating rotating rod 502 drives the valve plate 503 to rotate, and the rotating valve plate 503 opens the conveying channel, and the rainwater after filtration and sedimentation flows through the conveying channel opened by the valve plate 503 through the outlet pipe 4 into the interior of the connecting elbow 6. Because the diameter of the connecting elbow 6 is smaller than the diameter of the outlet pipe 4, the cross-sectional area of the rainwater flow is reduced, and the reduction in the cross-sectional area of the rainwater flow increases the pressure of the rainwater flow, thereby increasing the flow rate of the rainwater.
[0026] At the same time, the drooping pipe connected to the elbow 6 is used to increase the impact force of the rainwater with increased flow rate. The rainwater with impact force flows into the interior of the drainage pipe 7 through the output end of the connection elbow 6 and impacts the first sleeve 802 at the same time. Under the action of the impact force of the rainwater, the first sleeve 802 and the active fan blades 803 are driven to rotate on the surface of the mounting rod 801. The rotating first sleeve 802 and the active fan blades 803 drive the second sleeve 805 to rotate through the connecting rod 804. The rotating second sleeve 805 drives the driven fan blades 806 to rotate rapidly on the surface of the mounting rod 801. The rapid rotation of the driven fan blades 806 accelerates the flow rate of the rainwater in the drainage pipe 7. The rainwater with accelerated flow rate is quickly discharged through the output end of the drainage pipe 7, thereby realizing the function of quickly discharging rainwater, avoiding the slow discharge of rainwater, thereby causing the high pressure of rainwater overflow inside the rainwater pipe network, and causing the rainwater to block the rainwater pipe network.
[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
