Description

Technical Field

[0001] This utility model relates to the field of municipal infrastructure technology, and in particular to a municipal road water supply and drainage device. Background Technology

[0002] Urban drainage systems are engineering facilities systems for treating and discharging urban sewage and rainwater, and are an integral part of urban public utilities. Urban drainage system planning is an integral part of urban master planning. Urban drainage systems typically consist of drainage pipes and sewage treatment plants. Under a system of separate sewage and rainwater management, sewage is collected through drainage pipes, sent to sewage treatment plants, and then discharged into water bodies or recycled; rainwater runoff is collected through drainage pipes and discharged into nearby water bodies.

[0003] In existing technologies, the drainage grid openings of the rainwater collection troughs on both sides of the road are relatively large, causing garbage, fallen leaves from the green belts, and other debris to fall into the rainwater collection troughs, which can easily lead to blockages. Cleaning is relatively easy at the openings on the road surface, but it is difficult to clean the debris from rainwater collection troughs that are buried deep underground. Therefore, we propose a municipal road water supply and drainage device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a municipal road water supply and drainage device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A municipal road water supply and drainage system, comprising:

[0007] A rainwater collection trough, which is connected to a drain pipe via a siphon tube assembly, and a filter screen assembly is provided on the siphon tube assembly;

[0008] The rainwater collection trough is equipped with a guardrail and a net bag is installed inside the rainwater collection trough.

[0009] Preferably, the siphon tube assembly includes a bend, the two ends of which are respectively located in the rainwater collection trough and the drain pipe. The bend located in the rainwater collection trough is connected to an extension tube, and the side wall of the extension tube has multiple water inlets. The filter screen assembly is located on the extension tube.

[0010] Preferably, the filter assembly includes a collar slidably connected to the extension tube, a plurality of vertical rods are fixedly connected to the lower end of the collar, a float is fixedly connected to the lower end of the vertical rods, a first mesh plate is fixedly connected to the inner wall of the float, a plurality of baffles are fixedly connected to the inlet, and a second mesh plate is fixedly connected to the inner wall of the lower end of the extension tube.

[0011] Preferably, the float is annular and made of hollow plastic.

[0012] Preferably, the net includes a frame, a barrier net is fixedly connected inside the frame, an extension rod is fixedly connected to the upper end of the frame, and a handle is fixedly connected to the upper side wall of the extension rod.

[0013] Preferably, the stop bar and the vertical bar are arranged perpendicular to each other, and the stop bar is arc-shaped.

[0014] Preferably, both the rainwater collection trough and the drainage pipe are located in the soil, and the horizontal position of the drainage pipe is lower than the horizontal position of the rainwater collection trough.

[0015] Preferably, sliders are fixedly connected to both sides of the barrier net, and the inner wall of the rain collection trough is provided with vertical grooves that match the sliders.

[0016] Preferably, the float is provided with multiple baffles.

[0017] Preferably, the lower surface of the guardrail is provided with a groove, and the handle is located in the groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, by setting up a rainwater collection trough in conjunction with a drainage pipe, allows rainwater to flow into the rainwater collection trough during rainy weather. As the water level in the rainwater collection trough rises, the rainwater overflows the siphon pipe assembly and then enters the drainage pipe through the siphon pipe. Furthermore, the filter screen assembly prevents various debris from entering the drainage pipe, which not only effectively avoids clogging of the drainage pipe but also greatly facilitates the cleaning of the drainage device by sanitation workers.

[0020] 2. This utility model, by setting up a filter screen assembly, uses a vertical rod and a baffle rod to form a filter screen for filtering the water inlet, and uses a float block to cooperate with the first screen plate and the second screen plate to make the two screen plates stick together to form a screen plate with denser mesh. This can effectively prevent debris from entering the drain pipe through the siphon pipe assembly, and also allow the debris blocked by the filter screen assembly to fall off after the drainage is completed.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-7 A municipal road water supply and drainage device includes a rainwater collection trough 1, which is connected to a drain pipe 2 via a siphon assembly. A filter screen assembly is provided on the siphon assembly. Both the rainwater collection trough 1 and the drain pipe 2 are located in the soil 16, and the horizontal position of the drain pipe 2 is lower than the horizontal position of the rainwater collection trough 1.

[0031] The rainwater collection trough 1 is set at the edge of the road and is mainly used to collect rainwater. The rainwater collection trough 1 does not need to be connected to the rainwater collection trough 1 along the road. After entering the rainwater collection trough 1, the rainwater needs to enter the drain pipe 2 through the siphon pipe assembly and then be discharged into the nearby water body along the drain pipe 2. Since the siphon drainage is used, the position of the drain pipe 2 needs to be lower than the rainwater collection trough 1 to ensure that the siphon phenomenon can be stably formed.

[0032] The rain collection trough 1 is equipped with a guardrail 3, and a net bag is installed inside the rain collection trough 1. The net bag includes a frame 12, and a barrier net 13 is fixedly connected inside the frame 12. An extension rod 14 is fixedly connected to the upper end of the frame 12, and a handle 15 is fixedly connected to the upper side wall of the extension rod 14. Slider blocks 17 are fixedly connected to both sides of the barrier net 13. The inner wall of the rain collection trough 1 has vertical grooves that match the sliders 17. A recessed groove is formed on the lower surface of the guardrail 3, and the handle 15 is located in the recessed groove.

[0033] In this design, a cement slab or metal plate with slotted holes is used to prevent pedestrians and non-motorized vehicles walking along the road edge from falling into the rainwater collection trough 1. A net is set up to collect debris that falls into the rainwater collection trough 1, such as fallen leaves from plants in the green belt or garbage that can pass through the guardrail 3. After entering the rainwater collection trough 1 with rainwater, these debris will fall into the net as the rainwater in the rainwater collection trough 1 drains out. When sanitation workers clean the rainwater collection trough 1, they can first use tools to remove the guardrail 3, and then pull the handle 15 to take the net out of the rainwater collection trough 1, which makes it easier to clean the debris in the rainwater collection trough 1. On this basis, a slider 17 is set up in conjunction with the vertical groove to help sanitation workers position the net after cleaning the debris. The sink trough can store the handle 15 and provide a certain degree of protection.

[0034] It should be noted that when sanitation workers remove the net bag, they can adjust the net bag to an inclined position before removing it from the rainwater collection trough 1 to avoid interference between the net bag and the siphon pipe assembly, which would prevent the net bag from being removed.

[0035] More specifically, the siphon tube assembly includes a bend 4, with the two ends of the bend 4 located in the rainwater collection trough 1 and the drain pipe 2, respectively. The bend 4 located in the rainwater collection trough 1 is connected to an extension pipe 5, and the side wall of the extension pipe 5 is provided with multiple water inlets. The filter screen assembly is located on the extension pipe 5.

[0036] The number of siphon components is designed based on the drainage area of ​​a single rainwater collection trough 1 and the local rainfall (in millimeters / 24 hours). For example, the larger the area that rainwater collection trough 1 is responsible for, the more likely there is to be heavy rain in the area, so more siphon components are installed.

[0037] During rainy weather, after rainwater enters the rainwater collection trough 1 along the road surface, the water level overflows the top of the bend 4. The rainwater then enters the bend 4 through the extension pipe 5 and flows into the drain pipe 2, forming a siphon effect. Even after the rain ends, the siphon assembly can continue to discharge water from the rainwater collection trough 1 until the water level in the rainwater collection trough 1 is lower than the lower opening of the bend 4 in the rainwater collection trough 1. The filter assembly can effectively prevent debris in the rainwater from entering the siphon assembly, thus reducing the need for cleaning the drain pipe 2.

[0038] It is worth mentioning that in this design, when the siphon assembly is draining water, the water level needs to overflow the top of the bend 4. At this time, the water level in the rainwater collection trough 1 is relatively high, and floating objects are located at the top of the extension pipe 5. The bottom of the extension pipe 5 does not contact the bottom of the drainage ditch. During the drainage process of the siphon assembly, the rainwater in the middle of the rainwater collection trough 1 is discharged first. This part of the rainwater contains less garbage such as fallen leaves and plastic bags that are easy to clog the filter screen assembly. At the same time, it is not easy to suck up the mud and sand at the bottom of the siphon, which can effectively ensure the drainage efficiency during rainfall and reduce the risk of clogging.

[0039] Furthermore, the filter assembly includes a collar 6 slidably connected to the extension tube 5. Multiple vertical rods 7 are fixedly connected to the lower end of the collar 6. A float 8 is fixedly connected to the lower end of each vertical rod 7. A first mesh plate 9 is fixedly connected to the inner wall of the float 8. Multiple baffles 10 are fixedly connected inside the water inlet. A second mesh plate 11 is fixedly connected to the inner wall of the lower end of the extension tube 5. The warp angle between the first mesh plate 9 and the second mesh plate 11 is 45° (both the first mesh plate 9 and the second mesh plate 11 are composed of an outer frame and internally perpendicular warp and weft threads). The baffles 10 are perpendicular to the vertical rods 7 and are arc-shaped.

[0040] Based on the above design, when the water level in the rainwater collection trough 1 rises, the float 8 moves upward under the influence of buoyancy, allowing the vertical rod 7 and the arc-shaped baffle to form a mesh-like filter at the inlet. The first mesh plate 9 and the second mesh plate 11 are attached to form a filter with a smaller mesh count. In this state, it can effectively block debris in the rainwater and prevent most of the debris from entering the drain pipe 2. After the rainfall ends, the collar 6, vertical rod 7, float 8, and first mesh plate 9 move downward under the action of gravity. At this time, most of the debris stuck between the vertical rod 7 and the baffle 10 will fall off under the action of gravity. After the first mesh plate 9 and the second mesh plate 11 separate, the two individual mesh plates have a larger mesh count, and the debris stuck between the first mesh plate 9 and the second mesh plate 11 is also easier to fall off. This can further prevent debris from remaining in the filter assembly, especially after the rainwater evaporates and sticks to the filter assembly, affecting the next drainage operation.

[0041] Furthermore, the float 8 is annular and made of hollow plastic. An extension rod 14 is fixedly connected to the side wall of the float 8. The extension rod 14 is made of elastic plastic. Multiple partitions 18 are provided inside the float 8. The use of hollow plastic material in the float 8 ensures that the buoyancy of the float 8 can drive the vertical rod 7 and the collar 6 to move upward. The multiple partitions 18 divide the float 8 into multiple cavities. Even if the float 8 is damaged after long-term use, some cavities can still provide buoyancy, thereby improving the service life of the float 8.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
