Description

Technical Field

[0001] The present application relates to the field of urban drainage technology, and in particular to a road rainwater and sewage pipe network drainage system. Background Art

[0002] The urban drainage system is an engineering facility system used to treat and remove urban sewage and rainwater. It is an indispensable part of urban public facilities. The urban drainage system is composed of a drainage network management system and a sewage treatment plant. When the sewage and rainwater diversion system is implemented, the city's rainwater drainage network and sewage drainage network are independently set up. The rainwater entering the rainwater network will be directly discharged into the natural water source, and the domestic sewage in the sewage drainage network needs to be discharged to the sewage treatment plant for treatment before being discharged into the natural water source. This can effectively reduce the sewage treatment pressure of the sewage treatment plant.

[0003] In the prior art, the Chinese utility model patent with the authorization announcement number CN219638076U discloses "a road rainwater and sewage drainage pipe network system", including a drainage mechanism, the drainage mechanism includes a drainage well, a diversion box is provided at the bottom of the drainage well, and the diversion box is divided into a buffer bin and an auxiliary bin by a vertical partition, a rectangular overflow hole is opened on the left side of the vertical partition and near the top, a transverse partition is provided in the auxiliary bin and near the bottom, and a valve mechanism is provided in the middle of the top of the transverse partition. In this road rainwater and sewage drainage pipe network system, when the buffer bin is full of rainwater, it means that the first rainwater conduit cannot quickly complete the discharge of rainwater. At this time, the rainwater in the buffer bin overflows from the rectangular overflow hole to the auxiliary bin, and the overflowing rainwater is introduced into the sewage drainage pipe network with the help of the valve mechanism in the auxiliary bin and the second rainwater conduit to relieve the drainage pressure of the rainwater drainage pipe network.

[0004] Although the road rainwater and sewage pipe network drainage system in the prior art has the function of guiding overflowing rainwater into the sewage drainage network with the help of the valve mechanism in the auxiliary bin and the second rainwater conduit to relieve the drainage pressure of the rainwater drainage network, this new type of road rainwater and sewage drainage pipe network system still has some shortcomings in practical applications. For example, when rainwater flows into the second rainwater conduit, a certain suction force will be formed downward, causing the rectangular block to be easily adsorbed on the top of the second rainwater conduit and close it, which not only affects the drainage efficiency, but may also cause poor drainage or even blockage.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In order to solve the problem that when rainwater flows into the second rainwater conduit, a certain suction force is formed downward, causing the rectangular block to be easily adsorbed on the top of the second rainwater conduit and close it, which not only affects the drainage efficiency but may also cause poor drainage or even blockage, the present application provides a road rainwater and sewage pipe drainage system.

[0007] The road rainwater and sewage pipe network drainage system provided in this application adopts the following technical solutions:

[0008] A road rainwater and sewage pipe network drainage system comprises a diversion box, a drainage well is fixed on the top surface of the diversion box, an inner pipe is placed inside the drainage well, a well cover is installed on the top surface of the inner pipe, and a detachable filter is also installed inside the inner pipe;

[0010] A drainage groove is provided on the partition, and a mounting pipe is fixed on one side of the partition above the second connecting pipe. A fixing plate is fixed on the drainage groove, and a guide rod passes through the fixing plate. A sealing plate is fixed to one end of the guide rod, and a connecting plate is installed on the other end through a thread. A reset spring is also sleeved on the outer wall of the guide rod, and the reset spring is located between the fixing plate and the connecting plate.

[0011] Preferably, a pair of connecting rods are fixed to one side of the sealing plate, and both of the connecting rods pass through the fixing plate.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0026] The present application embodiment discloses a road rainwater and sewage pipe network drainage system. Figure 1-Figure 5 A road rainwater and sewage pipe network drainage system includes a diversion box 1, a drainage well 2 is fixed on the top surface of the diversion box 1, an inner pipe 18 is placed inside the drainage well 2, a well cover 19 is installed on the top surface of the inner pipe 18, and a detachable filter screen 21 is also installed inside the inner pipe 18;

[0027] A partition 3 is fixed inside the flow dividing box 1, and a first connecting pipe 4 and a second connecting pipe 5 are respectively installed on the bottom of the flow dividing box 1 on both sides of the partition 3. A first drain pipe 6 is fixed to the bottom end of the first connecting pipe 4, and a second drain pipe 7 is fixed to the bottom end of the second connecting pipe 5.

[0028] A drainage groove 8 is provided on the partition 3, and a mounting pipe 9 is fixed on one side of the partition 3 above the second connecting pipe 5. A fixing plate 10 is fixed on the drainage groove 8, and a guide rod 11 passes through the fixing plate 10. A sealing plate 12 is fixed to one end of the guide rod 11, and a connecting plate 13 is installed on the other end through a thread. A return spring 14 is also sleeved on the outer wall of the guide rod 11, and the return spring 14 is located between the fixing plate 10 and the connecting plate 13; when in use, rainwater will flow through the drainage well 2 into the left side of the interior of the diversion box 1, and flow into the interior of the first drainage pipe 6 through the first connecting pipe 4, and then be discharged through the first drainage pipe 6. When the amount of rainwater is large, the rainwater will accumulate on the left side of the interior of the diversion box 1. When the rainwater reaches a certain height, the rainwater that flows into the interior of the diversion box 1 again through the drainage well 2 will impact the sealing plate 12 to move it, and at the same time the connecting plate 13 will squeeze The return spring 14 is compressed to deform the return spring 14. When the sealing plate 12 moves to a certain position, rainwater will pass through the drainage groove 8 and the mounting pipe 9, flow into the right side of the internal part of the diversion box 1, and then flow into the interior of the second drainage pipe 7 through the second connecting pipe 5, and then be discharged by the second drainage pipe 7, thereby alleviating the drainage pressure of the first drainage pipe 6. When rainwater flows in through the drainage well 2, the filter net 21 will filter impurities in the rainwater to prevent impurities from clogging the pipeline and causing poor drainage. When the rainfall stops and no rainwater flows into the drainage well 2, the elastic force of the return spring 14 can be used to push the connecting piece 13 to move, and the connecting piece 13 drives the guide rod 11 to move, and the guide rod 11 drives the sealing plate 12 to move until the sealing plate 12 re-seals the drainage groove 8, thereby preventing the second connecting pipe 5 from being closed during drainage.

[0029] Reference Figure 4 A pair of connecting rods 15 are also fixed on one side of the sealing plate 12, and the pair of connecting rods 15 both penetrate the fixing plate 10; this can increase the stability of the sealing plate 12 and prevent it from shaking.

[0030] Reference Figure 4 The fixing plate 10 is also provided with a plurality of through holes 16 to facilitate the flow of rainwater and reduce the impact of rainwater on the fixing plate 10 .

[0031] Reference Figure 5 A supporting annular plate 20 is also installed inside the inner tube 18, and a filter screen 21 is located on the top of the supporting annular plate 20; it is convenient to place or remove the filter screen 21, and it is convenient for the staff to clean or replace the filter screen 21.

[0032] Reference Figure 3 Two pairs of reinforcing ribs 17 are fixed on one side of the partition 3, and one side of the two pairs of reinforcing ribs 17 is fixed inside the diversion box 1; this can increase the stability of the partition 3 and make it less likely to bend.

[0033] Reference Figure 3 and Figure 4 The reinforcing rib 17 and the connecting rod 15 are made of stainless steel and are not easily corroded by rainwater.

[0034] Reference Figure 4 The length of the connecting rod 15 is greater than the length of the guide rod 11; this can prevent the connecting rod 15 from detaching from the fixing plate 10 to increase the stability of the guide rod 11 during movement, making it less likely to shake.

[0035] The implementation principle of the road rainwater and sewage pipe network drainage system of the embodiment of the present application is as follows: when in use, rainwater will flow into the left side of the interior of the diversion box 1 through the drainage well 2, and flow into the interior of the first drainage pipe 6 through the first connecting pipe 4, and then be discharged by the first drainage pipe 6. When the amount of rainwater is large, the rainwater will accumulate on the left side of the interior of the diversion box 1. When the rainwater reaches a certain height, the rainwater that flows into the interior of the diversion box 1 again through the drainage well 2 will impact the sealing plate 12 to move it. At the same time, the connecting piece 13 will squeeze the return spring 14 to deform the return spring 14. When the sealing plate 12 moves to a certain position, the rainwater will flow into the right side of the interior of the diversion box 1 through the drainage groove 8 and the mounting pipe 9, and then flow into the interior of the second drainage pipe 7 through the second connecting pipe 5, and then be discharged by the second drainage pipe 7, thereby alleviating the drainage pressure of the first drainage pipe 6. When rainwater flows in through the drainage well 2, the filter net 21 will filter impurities in the rainwater to prevent impurities from clogging the pipeline and causing the problem of poor drainage.

[0036] When the rainfall stops and no rainwater flows into the drainage well 2, the elastic force of the reset spring 14 can be used to push the connecting piece 13 to move, and the connecting piece 13 drives the guide rod 11 to move, and the guide rod 11 drives the sealing plate 12 to move until the sealing plate 12 re-seals the drainage groove 8, thereby preventing the second connecting pipe 5 from being closed during drainage.
