It helps to regulate rainwater runoff, reduce the burden on urban drainage systems, prevent and reduce urban waterlogging, and is also conducive to the collection and reuse of rainwater resources. Municipal rainwater storage and regulation equipment usually consists of a collection system, pretreatment facilities, storage tanks, purification facilities and discharge systems. Pretreatment facilities are used to remove large particles and sediments in rainwater, and purification facilities are used to purify rainwater and improve water quality. Finally, the discharge system is used to discharge rainwater in the storage tank to a designated location.

[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1-Figure 8 As shown, a municipal rainwater regulating and storing device is provided in the embodiment, including a primary sedimentation tank 1; a water inlet pipe 2 is fixedly installed on one side of the primary sedimentation tank 1, a water outlet pipe 3 is fixedly installed on the other side of the primary sedimentation tank 1, a filter is installed on one end of the water outlet pipe 3, an inclined plate 4 is fixedly installed on one side of the primary sedimentation tank 1 away from the water inlet pipe 2, a debris storage tank 5 is fixedly installed on one side of the inclined plate 4, and a separation component is arranged at the bottom end of the interior of the primary sedimentation tank 1;

[0039] The separation component includes a lifting filter plate 6 arranged inside the primary sedimentation tank 1, and the first guide rod 7 and the second guide rod 8 are symmetrically installed on both sides of the lifting filter plate 6. The first guide rod 7 is slidably installed on the inner wall of the first guide groove 9, and the second guide rod 8 is slidably installed on the inner wall of the second guide groove 10. The first guide groove 9 and the second guide groove 10 are both opened on the inner wall of the primary sedimentation tank 1, and one end of one of the second guide rods 8 is rotatably installed with a first connecting rod 11, and the other end of the first connecting rod 11 is rotatably installed with a rotating rod 12, and the end of the rotating rod 12 away from the first connecting rod 11 is fixedly installed with a driving rod 13, and the outer wall of the driving rod 13 is provided with a pushing component, and one end of the driving rod 13 is connected to a motor, and the motor and the external power supply are connected through a guide Line connection, by setting up a separation component, when it is necessary to separate the sediment in the primary sedimentation tank 1, the water inlet pipe 2 can be closed and the motor can be started, so that the motor drives the lifting filter plate 6 to move and tilt through the driving rod 13, the rotating rod 12, the first connecting rod 11 and the second guide rod 8, thereby driving the accumulated sediment in the primary sedimentation tank 1 to move to the debris storage tank 5 under the action of gravity, avoiding the problem of rapid accumulation of a large amount of sediment in the primary sedimentation tank 1 when there are many large particles of debris. At this time, the staff needs to close the primary sedimentation tank 1 for a long time to remove the sediment, thereby causing a decrease in work efficiency. The work of removing the sediment in the primary sedimentation tank 1 is more convenient and quick, and the working efficiency of the municipal rainwater storage device is improved.

[0040] See also Figure 4 , Figure 6 and Figure 7 As shown, the pushing assembly includes a first gear 14 arranged on the outer wall of the driving rod 13, a first tooth plate 15 is meshedly installed on the top end of the first gear 14, a second tooth plate 16 is fixedly installed on one end of the first tooth plate 15, a second gear 17 is meshedly installed on the top end of the second tooth plate 16, a connecting rod 18 is fixedly installed on one side of the second gear 17, and a scraper 19 is fixedly installed on the outer wall of the connecting rod 18. By setting the pushing assembly, when separating the sediment in the primary sedimentation tank 1, the driving rod 13 can drive the scraper 19 to rotate through the first gear 14, the first tooth plate 15, the second tooth plate 16, the second gear 17 and the connecting rod 18, so that the scraper 19 pushes the sediment at the top end of the primary sedimentation tank 1 close to the debris storage tank 5, thereby avoiding the sediment from easily staying at the horizontal top end of the primary sedimentation tank 1 close to the debris storage tank 5, thereby causing the separation effect of the separation assembly to decrease. The sediment that remains for a long time is also prone to deterioration and odor, which affects the purification effect of the device, thereby improving the separation effect of the sediment, thereby improving the stability and reliability of the separation assembly.

[0041] See also Figure 6 and Figure 7As shown, an eccentric wheel 20 is rotatably installed on one side of the scraper 19, and the eccentric wheel 20 is fixedly installed on the outer wall of the connecting rod 18, and the length between the two ends of the second tooth plate 16 is greater than half of the circumferential length of the outer wall of the second gear 17, so that when the second tooth plate 16 drives the scraper 19 to rotate through the second gear 17 and the connecting rod 18, the connecting rod 18 drives the eccentric wheel 20 to rotate by an angle greater than half of the circumference, so that when the second tooth plate 16 stops abutting against the second gear 17, the eccentric wheel 20 drives the connecting rod 18 and the scraper 19 to reset due to its own gravity.

[0042] See also Figure 6 and Figure 7 As shown, the outer wall of the first gear 14 is configured as a smooth portion and a gear portion, so that when the driving rod 13 drives the lifting filter plate 6 to rise, the first gear 14 does not mesh with the first tooth plate 15. When the driving rod 13 drives the lifting filter plate 6 to rotate, the first gear 14 meshes with the first tooth plate 15 again, thereby driving the pushing component to operate, so that the pushing component pushes and separates the last sediment in the primary sedimentation tank 1, thereby improving the separation effect of the device on the sediment.

[0043] See also Figure 6 and Figure 7 As shown, the tooth block at the top of the second tooth plate 16 and the tooth block on the outer wall of the second gear 17 are both arranged in a ratchet shape, so that when the second tooth plate 16 moves in a direction close to the second gear 17, it can drive the second gear 17 to rotate, and when the second tooth plate 16 moves in a direction away from the second gear 17, it will not drive the second gear 17 to rotate, thereby avoiding the problem that when there is sediment remaining at the top of the primary sedimentation tank 1 close to the debris storage tank 5, the second tooth plate 16 is reset to drive the scraper 19 to rotate through the second gear 17 and the connecting rod 18, which easily causes the scraper 19 to push the remaining sediment back into the primary sedimentation tank 1, resulting in an increase in the sediment in the primary sedimentation tank 1, affecting the working efficiency of the device, thereby improving the stability and reliability of the pushing component.

[0044] To summarize, by cooperating with the second toothed plate 16, the second gear 17 and the eccentric wheel 20, when the second toothed plate 16 moves toward the direction approaching the second gear 17, the second toothed plate 16 can drive the second gear 17 to rotate, and the second gear 17 drives the eccentric wheel 20 to rotate an angle greater than half of the circumference through the connecting rod 18, and does not drive the second gear 17 to rotate when the second toothed plate 16 moves away from the second gear 17. At this time, the eccentric wheel 20 rotates and resets under the action of gravity, completing a complete circle, thereby preventing the scraper 19 from rotating in the opposite direction and resetting.

[0045] See also Figure 1 and Figure 6As shown, the rotation speed of the driving rod 13 is set to V, and V should satisfy the relationship V<, wherein r is the radius of the outlet pipe 3, P is the output power of the water pump, K is a fixed ratio of the water flow velocity to the output power of the water pump, R is the distance between the two ends of the rotating rod 12, a is the length of the inner wall of the primary sedimentation tank 1, and b is the width of the inner wall of the primary sedimentation tank 1. The speed at which the motor drives the lifting filter plate 6 to move through the driving rod 13, the rotating rod 12, the first connecting rod 11 and the second guide rod 8 is lower than the speed at which rainwater in the primary sedimentation tank 1 is discharged, so that when the lifting filter plate 6 moves, the rainwater remaining between the sediments has sufficient time to filter down, thereby improving the collection and utilization rate of rainwater, thereby improving the regulation and storage effect of the municipal rainwater regulation and storage device.

[0046] A construction method for a municipal rainwater storage device, the specific construction method comprising the following steps:

[0047] Step 1: Excavate the earth, measure and locate according to the design requirements and on-site conditions, determine the location, size and elevation, and then excavate the earth in layers;

[0048] Step 2: Foundation construction, laying of gravel cushion and reinforced concrete bottom plate, construction of anti-seepage layer, laying of two cloths and one membrane, welding and laying on the bottom of the pool;

[0049] Step 3: Module assembly, install the storage tank, sedimentation tank, purification tank and other modules;

[0050] Step 4: Laying the protective layer: Lay the protective layer around and on the top of the module water storage tank anti-seepage layer according to the design requirements;

[0051] Step 5: Backfilling. Before backfilling, the construction waste and debris in the foundation pit should be cleaned up. The soil quality should meet the design requirements, and then the rainwater storage device should be buried;

[0052] Step 6: Installation of electromechanical equipment, including installation of lifting water pumps, control cabinets and other electromechanical equipment;

[0053] Step 7: System testing and debugging. After the installation is completed, system testing and debugging are carried out to check whether the airtightness, drainage function and level control of the regulating reservoir meet the design requirements.

[0054] Embodiment 2

[0055] See also Figure 4 and Figure 5 As shown, compared with Example 1, as another implementation of the present invention, a concave-convex groove 21 is provided at one end of the second guide groove 10, so that when the second guide rod 8 drives the lifting filter plate 6 to move along the second guide groove 10, the second guide rod 8 vibrates through the concave-convex groove 21, thereby driving the sediment to vibrate through the lifting filter plate 6, thereby promoting the falling of rainwater between the sediments, and further improving the rainwater collection effect of the municipal rainwater storage device.

[0056] See also Figure 6 and Figure 8 As shown, the rotating rod 12 is composed of a rotating rod and a telescopic rod. One end of the telescopic rod is slidably installed on the inner wall of one end of the rotating rod. A guide protection rod 22 is fixedly installed on one end of the telescopic rod. A spring 23 is wound around the outer wall of the guide protection rod 22. The rotating rod and the telescopic rod are connected by the spring 23. When the second guide rod 8 drives the lifting filter plate 6 to vibrate, the second guide rod 8 drives the telescopic rod to move, and the telescopic rod drives the spring 23 to elastically deform and accumulate elastic properties. When the second guide rod 8 stops vibrating, the spring 23 releases elastic potential energy, elastically deforms, and pulls the telescopic rod to reset, thereby avoiding the problem of motion interference between the second guide rod 8 and the rotating rod 12 when vibrating, thereby improving the reliability and stability of the device.

[0057] See also Figure 2 and Figure 3 As shown, a sensing groove 24 is provided on one side of the inner wall of the primary sedimentation tank 1, a water groove 25 is provided on one side of the sensing groove 24, a float 26 is slidably installed on the inner side of the water groove 25, and an optical signal transmitting device 27 and an optical signal receiving device 28 are respectively installed on both sides of the sensing groove 24. When there is a lot of sediment in the primary sedimentation tank 1 and the rainwater level is too high, the float 26 can rise, thereby blocking the optical signal receiving device 28 from receiving the optical signal sent by the optical signal transmitting device 27, so that the optical signal receiving device 28 sends a signal to close the water inlet pipe 2, start the motor and notify the staff, thereby avoiding the problem that when the municipal rainwater regulation and storage device is actually operating, the staff finds it difficult to timely observe and discover that there are too many sediments in the primary sedimentation tank 1, thereby making it difficult to separate the sediments in time, which affects the working effect of the municipal rainwater regulation and storage device, thereby improving the working effect of the municipal rainwater regulation and storage device.

[0058] Working principle: On rainy days, the rainwater collection system in the municipal rainwater storage device transports the collected rainwater to the primary sedimentation tank 1 through the water inlet pipe 2, so that the large particles of debris in the rainwater settle by gravity, and the clean water on the top layer is discharged from the primary sedimentation tank 1 through the water outlet pipe 3;

[0059] When a lot of sediment accumulates at the bottom of the primary sedimentation tank 1, the liquid level of rainwater in the primary sedimentation tank 1 rises, so that the rainwater fills the sensing tank 24, and the buoyancy of the rainwater in the sensing tank 24 drives the float 26 to move upward, and the float 26 moves to between the optical signal transmitting device 27 and the optical signal receiving device 28, thereby preventing the optical signal receiving device 28 from receiving the optical signal emitted by the optical signal transmitting device 27, so that the optical signal receiving device 28 sends a signal to control the water inlet pipe 2 and the water outlet pipe 3 to be closed, and at the same time, the motor is started, the motor drives the driving rod 13 to rotate, the driving rod 13 drives the rotating rod 12 to rotate, the rotating rod 12 drives the first connecting rod 11 to move, the first connecting rod 11 drives the second guide rod 8 to move, the second guide rod 8 drives the lifting filter plate 6 to move upward, the lifting filter plate 6 drives the first guide rod 7 to move, and when the first guide rod 7 moves to the top of the first guide groove 9, the second guide rod 8 continues to move along the second guide groove 9. The groove 10 moves, so that the second guide rod 8 drives one end of the lifting filter plate 6 to rotate, so that the lifting filter plate 6 is tilted, and the sediment is promoted to move along the debris storage tank 5 and the inclined plate 4 into the debris storage tank 5. At the same time, the second guide rod 8 moves along the concave-convex groove 21, so that the lifting filter plate 6 vibrates, thereby promoting the rainwater between the sediments to pass through the lifting filter plate 6 and fall into the bottom of the primary sedimentation tank 1, thereby improving the utilization rate of rainwater. At this time, the driving rod 13 drives the first gear 14 to vibrate, the first gear 14 drives the first tooth plate 15 to move, the first tooth plate 15 drives the second tooth plate 16 to move, the second tooth plate 16 drives the second gear 17 to vibrate, the second gear 17 drives the connecting rod 18 to rotate, and the connecting rod 18 drives the scraper 19 to rotate, so that the scraper 19 pushes the sediment at the top of the primary sedimentation tank 1 close to the debris storage tank 5. At this time, the optical signal receiving device 28 sends a signal to notify the staff;

[0060] After the sediment in the primary sedimentation tank 1 is moved into the debris storage tank 5, the staff can control the motor to make the motor rotate in the opposite direction, thereby driving the separation component to reset, and then driving the first tooth plate 15 to reset, and the first tooth plate 15 drives the second tooth plate 16 to reset. When the second tooth plate 16 stops abutting against the second gear 17, the eccentric wheel 20 rotates and resets under the action of gravity, thereby driving the scraper 19 to reset through the connecting rod 18. At this time, the staff can open the water inlet pipe 2 to restore the normal operation of the municipal rainwater storage device.

[0061] Other technologies of this embodiment adopt existing technologies.
