In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The road drainage system 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, the embodiment of the present invention includes a road base 1, a first drainage pipe 21, a second drainage pipe 22, a third drainage pipe 23 and a fourth drainage pipe 24. The first drainage pipe 21 is located below the road base 1 and extends along the length direction of the road base 1 (such as Figure 2 The second drainage pipe 22 is located below the first drainage pipe 21 and extends along the width direction of the road substrate 1 (as shown in the first direction). Figure 1 and Figure 2The second drain pipe 22 extends in the second direction as shown, the second drain pipe 22 is optionally connected to the first drain pipe 21, the third drain pipe 23 is located below the second drain pipe 22 and extends along the length direction of the road base 1, the third drain pipe 23 is optionally connected to the second drain pipe 22, the fourth drain pipe 24 is located below the third drain pipe 23 and extends along the width direction of the road base 1, and the fourth drain pipe 24 is optionally connected to the third drain pipe 23.

[0037] Therefore, through such an arrangement, rainwater or other surface water above the road base 1 can enter the first drain pipe 21 and extend along the length direction of the road base 1 through the first drain pipe 21, so that rainwater or other surface water can be quickly collected along the natural flow direction of the road, thereby improving drainage efficiency.

[0038] When the first liquid level in the first drain pipe 21 is greater than the first preset value, the first drain pipe 21 and the second drain pipe 22 are controlled to be connected, so that the liquid in the first drain pipe 21 flows into the second drain pipe 22; when the second liquid level in the second drain pipe 22 is greater than the second preset value, the second drain pipe 22 and the third drain pipe 23 are controlled to be connected, so that the liquid in the second drain pipe 22 flows into the third drain pipe 23; when the third liquid level in the third drain pipe 23 is greater than the third preset value, the third drain pipe 23 and the fourth drain pipe 24 are controlled to be connected, so that the liquid in the third drain pipe 23 flows into the fourth drain pipe 24, thereby realizing a multi-level drainage network according to the amount of rainwater or other surface water above the road base 1, improving the capacity of the road drainage system 100, so that the road drainage system 100 can alleviate the drainage pressure caused by long-term heavy rainstorms and reduce the occurrence of urban waterlogging and other phenomena.

[0039] At the same time, since the first drain pipe 21 and the third drain pipe 23 extend along the length direction of the road base 1 and the second drain pipe 22 and the fourth drain pipe 24 extend along the width direction of the road base 1, in the process of rainwater or other surface water flowing from the first drain pipe 21 to the second drain pipe 22, the third drain pipe 23 and the fourth drain pipe, the water flow can be more evenly distributed to the entire road drainage system 100, thereby avoiding excessive water flow in a certain area causing pipe blockage or damage.

[0040] In addition, rainwater or other surface water above the road base 1 can also enter the second drain pipe 22 and extend along the width direction of the road base 1 through the second drain pipe 22, so as to collect rainwater or other surface water in the middle area of ​​the road base 1, further reduce water accumulation, and improve the reliability of the road drainage system 100.

[0041] According to the road drainage system 100 of the embodiment of the present invention, the first drainage pipe 21 is located below the road base 1 and extends along the length direction of the road base 1, the second drainage pipe 22 is located below the first drainage pipe 21 and extends along the width direction of the road base 1, the second drainage pipe 22 is optionally connected to the first drainage pipe 21, the third drainage pipe 23 is located below the second drainage pipe 22 and extends along the length direction of the road base 1, the third drainage pipe 23 is optionally connected to the second drainage pipe 22, the fourth drainage pipe 24 is located below the third drainage pipe 23 and extends along the width direction of the road base 1, and the fourth drainage pipe 24 is optionally connected to the third drainage pipe 23, so that a multi-level drainage network is realized according to the amount of rainwater or other surface water above the road base 1, the capacity of the road drainage system 100 is improved, so that the road drainage system 100 can alleviate the drainage pressure caused by long-term heavy rainstorms and reduce the occurrence of urban waterlogging and other phenomena.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, there are two first drainage pipes 21 located on both sides of the road substrate 1 in the width direction, and there are multiple second drainage pipes 22 spaced apart along the length direction of the road substrate 1. Thus, the layout of multiple second drainage pipes 22 and two first drainage pipes 21 further improves drainage efficiency and reduces accumulation.

[0043] Furthermore, the upper surface of the road base 1 is an upwardly convex curved surface, the center point of the road base 1 is the highest point, and the two ends of the road base 1 along the width direction are the lowest points. It can be understood that, through such a setting, the rainwater or other surface water above the road base 1 flows toward the two ends of the road base 1 along the width direction, thereby, the rainwater or other surface water above the road base 1 first flows into the second drainage pipe 22, and then flows into the first drainage pipe 21, thereby realizing diversion, further improving drainage efficiency, and reducing road surface water.

[0044] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the road base 1 has a first mounting hole 11 and a second mounting hole 12 penetrating the road base 1 in the up-down direction, and the road drainage system 100 further includes a first drainage well 31 and a second drainage well 32. The first drainage well 31 is located in the first mounting hole 11 and the lower end is connected to the first drainage pipe 21, and the second drainage well 32 is located in the second mounting hole 12 and the lower end is connected to the second drainage pipe 22. Thus, rainwater or other surface water above the road base 1 enters the first drainage pipe 21 through the first drainage well 31, and enters the second drainage pipe 22 through the second drainage well 32, thereby realizing diversion, further improving the drainage efficiency of the road drainage system 100, and reducing road surface water.

[0045] Optionally, there are multiple first drainage wells 31, and the lower ends of the multiple first drainage wells 31 are respectively connected to the two first drainage pipes 21; there are multiple second drainage wells 32, and the lower ends of the multiple first drainage wells 31 are respectively connected to the multiple second drainage pipes 22.

[0046] In some embodiments of the present invention, Figure 1-Figure 3 As shown, there are two manhole cover 41 assemblies 4 and they include manhole covers 41 and a first driving mechanism 42. The two manhole covers 41 are respectively covered on the upper end surfaces of the first drainage well 31 and the second drainage well 32. The manhole cover 41 has a drainage hole 411. The first driving mechanism 42 is used to drive the manhole cover 41 to move in the up and down directions. At the upper limit position of the manhole cover 41, the upper end surface of the manhole cover 41 is flush with the upper end surface of the road base 1.

[0047] It can be understood that rainwater or other surface water above the road base 1 enters the first drainage well 31 through the drainage hole 411 and flows into the first drainage pipe 21, and rainwater or other surface water above the road base 1 enters the second drainage well 32 through the drainage hole 411 and flows into the second drainage pipe 22. Therefore, the manhole cover 41 effectively prevents debris from entering the first drainage pipe 21 and the second drainage pipe 22.

[0048] At the same time, when the flow rate of rainwater or other surface water above the road base 1 is too fast or the rainwater level is high, the first driving mechanism 42 drives the manhole cover 41 to move upward, so that a certain gap is generated between the outer edge of the manhole cover 41 and the inner top wall of the first drainage well 31 and the second drainage well 32, thereby increasing the amount of water flowing into the first drainage well 31 and the second drainage well 32, increasing the drainage volume to achieve rapid drainage, and further reducing road surface water. In addition, at the upper limit position of the manhole cover 41, the upper end surface of the manhole cover 41 is flush with the upper end surface of the road base 1, which will not affect the normal use of vehicles or pedestrians above the road base 1, further improving reliability.

[0049] Optionally, the first driving mechanism 42 is an electric telescopic rod, which is installed on the inner walls of the first drainage well 31 and the second drainage well 32 by bolts, and the output end of the electric telescopic rod is fixedly connected to the well cover 41 by bolts.

[0050] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the manhole cover 41 assembly 4 also includes a flow rate sensor 43, which is arranged on the bottom wall of the drainage hole 411. Therefore, the flow rate sensor 43 can obtain the flow rate of the liquid entering the first drainage well 31 and the second drainage well 32 in real time, and the electrical signal collected by the flow rate sensor 43 is converted into a digital signal through the information conversion module, and the data judgment module is used to judge whether to control the first driving mechanism 42 to drive the manhole cover 41 to move in the up and down direction, so as to further improve the reliability of the road drainage system 100.

[0051] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the road drainage system 100 further includes a garbage crushing device 5. There are two garbage crushing devices 5 and they include a second driving mechanism 51 and a crushing assembly 52. ​​The second driving mechanism 51 is used to drive a blade 521 of the crushing assembly 52 to rotate. The two crushing assemblies 52 are respectively arranged in the first drainage well 31 and the second drainage well 32.

[0052] It is understandable that garbage and other debris on the road base 1 may enter the first drainage pipe 21 through the first drainage well 31 or enter the second drainage pipe 22 through the second drainage well 32 and cause blockage. Therefore, the blade 521 of the crushing assembly 52 is driven to rotate by the second driving mechanism 51, so as to crush the impurities and garbage in the flowing water, so that the garbage and other debris are crushed into small particles of garbage, which are then discharged with the water flow, avoiding blockage, ensuring the drainage effect of the road drainage system 100, and improving reliability.

[0053] Further, the second driving mechanism 51 includes a first reduction box 511 and a first motor 512, and the crushing assembly 52 includes a crushing rod 522 and a blade 521. One axial end of the crushing rod 522 is rotatably connected to the output end of the first reducer, and the blade 521 is arranged on the outer peripheral wall of the crushing rod 522. Thus, the power output by the first motor 512 drives the crushing rod 522 to rotate through the first reducer, thereby driving the blade 521 to rotate, and then the blade 521 crushes the impurities and garbage. Optionally, there are one or more crushing rods 522. Optionally, the first bearing 53 is installed at one end of the crushing rod 522 that is away from the first reducer in the axial direction, and is used to support the rotation of the crushing rod 522 and reduce friction.

[0054] Furthermore, the manhole cover 41 assembly 4 is two and includes a manhole cover 41 and a first driving mechanism 42. The two manhole covers 41 are respectively covered on the upper end surfaces of the first drainage well 31 and the second drainage well 32. The manhole cover 41 has a drainage hole 411. The first driving mechanism 42 is used to drive the manhole cover 41 to move in the up and down directions. Therefore, the first driving mechanism 42 drives the manhole cover 41 to move upward, so that a certain gap is generated between the outer edge of the manhole cover 41 and the inner top wall of the first drainage well 31 and the second drainage well 32. In the process of increasing the amount of water flowing into the first drainage well 31 and the second drainage well 32, the possibility of garbage and other debris entering is also increased. Therefore, the garbage crushing device 5 is used to effectively prevent blockage and discharge the water to flow smoothly.

[0055] In some embodiments of the present invention, Figure 1-Figure 3As shown, the first drain pipe 21 is connected to the second drain pipe 22 through the first connecting pipe 61, and the first connecting pipe 61 is provided with a first valve 611. Thus, the connection between the first drain pipe 21 and the second drain pipe 22 is realized through the first connecting pipe 61, and the connection or disconnection between the first drain pipe 21 and the second drain pipe 22 is controlled by the first valve 611, so that the second drain pipe 22 can be optionally connected to the first drain pipe 21, thereby improving reliability.

[0056] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the second drain pipe 22 is connected to the third drain pipe 23 through the second connecting pipe 62, and the second connecting pipe 62 is provided with a second valve 621. Thus, the second drain pipe 22 and the third drain pipe 23 are connected through the second connecting pipe 62, and the connection or disconnection of the second drain pipe 22 and the third drain pipe 23 is controlled by the second valve 621, so that the second drain pipe 22 can be optionally connected to the third drain pipe 23, thereby improving reliability.

[0057] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the third drain pipe 23 is connected to the fourth drain pipe 24 through the third connecting pipe 63, and the third connecting pipe 63 is provided with a third valve 631. Thus, the third drain pipe 23 and the fourth drain pipe 24 are connected through the third connecting pipe 63, and the connection or disconnection of the third drain pipe 23 and the fourth drain pipe 24 is controlled by the third valve 631, so that the fourth drain pipe 24 can be optionally connected to the third drain pipe 23, thereby improving reliability.

[0058] Furthermore, if Figure 4 As shown, the first valve 611, the second valve 621 and the third valve 631 all include a valve core 6111, a second reduction box 6112, a second motor 6113, a connecting shaft 6114, a second bearing 6115 and a flow channel hole, wherein both ends of the valve core 6111 are connected to the connecting shaft 6114, a flow channel hole is provided in the middle of the valve core 6111, the valve core 6111 is respectively connected to the second bearing 6115 and the second reduction box 6112 through the connecting shaft 6114, and a second motor 6113 is installed on one side of the second reduction box 6112.

[0059] Thus, when the control system issues an opening command, the second motor 6113 starts to rotate, and the second motor 6113 converts the rotational motion into the linear or rotational motion of the connecting shaft 6114 through the second reduction box 6112, so that the connecting shaft 6114 drives the valve core 6111 to move, so that its flow channel hole is aligned with the upstream and downstream flow channels of the pipeline, and the fluid can freely pass through the valve flow channel to achieve connection. Or, when the control system issues a closing command, the second motor 6113 rotates in the opposite direction, and the second motor 6113 drives the valve core 6111 to move through the second reduction box and the connecting shaft 6114, and the valve core 6111 moves to the closed position, the flow channel hole is misaligned with the upstream and downstream flow channels of the pipeline or is completely closed, and the fluid cannot pass through the valve flow channel to achieve disconnection.

[0060] Furthermore, the tops and bottoms of the first valve 611, the second valve 621 and the third valve 631 are welded with connecting flanges 6117, thereby facilitating the first valve 611 to be installed on the first connecting pipe 61, the second valve 621 to be installed on the second connecting pipe 62, and the third valve 631 to be installed on the third connecting pipe 63 through the connecting flanges 6117, thereby improving the overall reliability.

[0061] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a first liquid level sensor 211 is provided in the first drain pipe 21. Thus, the liquid level height of the liquid in the first drain pipe 21 is obtained in real time through the first liquid level sensor 211, and the liquid level information can be converted into an electrical signal or other identifiable signal through the information acquisition module for analysis and processing by the control system. Further, the first liquid level sensor 211 is located on the inner top wall of the first drain pipe 21. Optionally, there are one or more first liquid level sensors 211.

[0062] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a second liquid level sensor 221 is provided in the second drain pipe 22. Thus, the liquid level height of the liquid in the second drain pipe 22 is obtained in real time through the second liquid level sensor 221, and the liquid level information can be converted into an electrical signal or other identifiable signal through the information acquisition module for analysis and processing by the control system. Further, the second liquid level sensor 221 is located on the inner top wall of the second drain pipe 22. Optionally, there are one or more second liquid level sensors 221.

[0063] In some embodiments of the present invention, Figure 1-Figure 3As shown, a third liquid level sensor 231 is provided in the third drain pipe 23. Thus, the liquid level height of the liquid in the third drain pipe 23 is obtained in real time through the third liquid level sensor 231, and the liquid level information can be converted into an electrical signal or other identifiable signal through the information acquisition module for analysis and processing by the control system. Further, the third liquid level sensor 231 is located on the inner top wall of the third drain pipe 23. Optionally, there are one or more third liquid level sensors 231.

[0064] The following describes a control method of the road drainage system 100 according to an embodiment of the present invention.

[0065] like Figure 1-Figure 5 As shown, according to the control method of the road drainage system 100 of the embodiment of the present invention, the road drainage system 100 is as described above. The control method of the road drainage system 100 includes:

[0066] Obtaining the first liquid level height in the first drain pipe 21. It is understandable that the first liquid level height in the first drain pipe 21 can be obtained in real time by the first liquid level sensor 211 disposed in the first drain pipe 21, so as to determine whether the first drain pipe 21 has reached the limit value by comparing the first liquid level height obtained in real time with the first preset value.

[0067] When the first liquid level is greater than the first preset value, the first drain pipe 21 is controlled to be connected to the second drain pipe 22. Therefore, when the first liquid level in the first drain pipe 21 obtained in real time through the above steps is greater than the first preset value, it is judged that the first drain pipe 21 has reached the limit value. At this time, the first drain pipe 21 and the second drain pipe 22 are controlled to be connected, so that the liquid in the first drain pipe 21 flows to the second drain pipe 22, thereby relieving the pressure of the first drain pipe 21, ensuring the drainage effect of the road drainage system 100, and further reducing the occurrence of urban waterlogging and other phenomena.

[0068] Furthermore, the first drain pipe 21 is connected to the second drain pipe 22 via the first connecting pipe 61, and the first connecting pipe 61 is provided with a first valve 611. Thus, when the first liquid level is greater than the first preset value, the first drain pipe 21 and the second drain pipe 22 are connected via the first valve 611, further improving the reliability of the road drainage system 100.

[0069] According to the control method of the road drainage system 100 of the embodiment of the present invention, a first liquid level height in the first drainage pipe 21 is obtained. When the first liquid level height is greater than a first preset value, the first drainage pipe 21 and the second drainage pipe 22 are controlled to be connected, so that the liquid in the first drainage pipe 21 flows to the second drainage pipe 22, thereby relieving the pressure in the first drainage pipe 21, ensuring the drainage effect of the road drainage system 100, and further reducing the occurrence of phenomena such as urban waterlogging.

[0070] In some embodiments of the present invention, Figure 5 As shown, the second liquid level height in the second drain pipe 22 is obtained. It is understandable that the second liquid level height in the second drain pipe 22 can be obtained in real time by the second liquid level sensor 221 disposed in the second drain pipe 22, so as to determine whether the second drain pipe 22 has reached the limit value by comparing the second liquid level height obtained in real time with the second preset value.

[0071] When the second liquid level is greater than the second preset value, the second drain pipe 22 is controlled to be connected to the third drain pipe 23. Therefore, when the second liquid level in the second drain pipe 22 obtained in real time through the above steps is greater than the second preset value, it is judged that the second drain pipe 22 has reached the limit value. At this time, the second drain pipe 22 is controlled to be connected to the third drain pipe 23, so that the liquid in the second drain pipe 22 flows to the third drain pipe 23, thereby relieving the pressure of the second drain pipe 22, ensuring the drainage effect of the road drainage system 100, and further reducing the occurrence of urban waterlogging and other phenomena.

[0072] Furthermore, the second drain pipe 22 is connected to the third drain pipe 23 through the second connecting pipe 62, and the second connecting pipe 62 is provided with a second valve 621. Therefore, when the second liquid level height is greater than the second preset value, the second drain pipe 22 is controlled to be connected to the second drain pipe 22 through the second valve 621, further improving the reliability of the road drainage system 100.

[0073] Obtain the third liquid level in the third drain pipe 23. It is understandable that the third liquid level in the third drain pipe 23 can be obtained in real time by the third liquid level sensor 231 disposed in the third drain pipe 23, so as to determine whether the third drain pipe 23 has reached the limit value by comparing the third liquid level obtained in real time with the third preset value.

[0074] When the third liquid level height is greater than the third preset value, the third drain pipe 23 is controlled to be connected to the fourth drain pipe 24. When the third liquid level height is greater than the third preset value, the third drain pipe 23 is controlled to be connected to the third drain pipe 23. Thus, when the third liquid level height in the third drain pipe 23 obtained in real time through the above steps is greater than the third preset value, it is judged that the third drain pipe 23 has reached the limit value. At this time, the third drain pipe 23 is controlled to be connected to the fourth drain pipe 24, so that the liquid in the third drain pipe 23 flows to the fourth drain pipe 24, thereby relieving the pressure of the third drain pipe 23, ensuring the drainage effect of the road drainage system 100, and further reducing the occurrence of urban waterlogging and other phenomena.

[0075] Furthermore, the third drain pipe 23 is connected to the fourth drain pipe 24 through the third connecting pipe 63, and the third connecting pipe 63 is provided with a third valve 631. Therefore, when the third liquid level height is greater than the third preset value, the third drain pipe 23 is controlled to be connected to the third drain pipe 23 through the third valve 631, further improving the reliability of the road drainage system 100.

[0076] Thereby, a multi-level drainage network is realized, and the capacity of the road drainage system 100 is improved, so that the road drainage system 100 can alleviate the drainage pressure caused by long-term heavy rainstorms and reduce the occurrence of urban waterlogging and other phenomena.

[0077] In some embodiments, the road drainage system 100 can be connected to the information collection module, the information conversion module, the data judgment module and the control module respectively. For example, the information collection module is connected to the first liquid level sensor 211, the second liquid level sensor 221, the third liquid level sensor 231 and the flow rate sensor 43 respectively, the information collection module is connected to the information conversion module, the information conversion module is connected to the data judgment module, the data judgment module is connected to the control module, and the control module is connected to the first driving mechanism 42, the first valve 611, the second valve 621 and the third valve 631 respectively, so as to realize real-time monitoring and control, realize rapid drainage, and effectively solve the problems of urban waterlogging. At the same time, the road drainage system 100 can also be connected to the server through a wireless network, and the server is connected to the control platform of the meteorological service station.
