Description

Technical Field

[0001] This utility model relates to the technical field of municipal road drainage equipment, specifically a new type of municipal road drainage device. Background Technology

[0002] Drainage systems along municipal roads play a crucial role in urban infrastructure, primarily by effectively removing rainwater to prevent road flooding and waterlogging of the surrounding environment, thereby ensuring traffic safety, extending the service life of roads, and improving the city's drainage capacity. These drainage structures include various parts such as side ditches, storm drains, drainage pipes, drainage wells, inspection wells, and stormwater regulating ponds. They work together to ensure that rainwater can be quickly collected, discharged, and flow into the municipal drainage system or natural water bodies. The working principle of the drainage structure is based on gravity and fluid mechanics. During the design, reasonable slopes and drainage channels are used to ensure that rainwater enters the pipe system through storm drains and is finally discharged into the drainage area or water body. For example, a municipal road drainage device disclosed in authorization announcement number CN217782303U includes a vertical pipe installed in the foundation, a horizontal pipe installed in the foundation, and a drainage cover. The vertical pipe and the horizontal pipe are connected. The cover is located directly above the vertical pipe and is flush with the bottom road surface. The cover has several water inlet holes. A funnel-shaped filter chamber with a wider top and narrower bottom is provided in the foundation. The cover covers and is hinged to the upper port of the filter chamber, and the lower end of the filter chamber is connected to... The upper end of the vertical pipe; the filter chamber is equipped with a filter box, which has several drain holes and several upward protrusions. The filter box in the filter chamber prevents debris from flowing into the drainage pipe and filters the water. The protrusions can lift up larger garbage and prevent garbage such as plastic bags from clogging the pipe. However, in the process of using the above technical solution, the vertical pipe and horizontal pipe form an L-shaped pipeline. On the one hand, rainwater, dead branches and leaves and other foreign objects will accumulate. On the other hand, it is difficult to form a continuous pipeline structure. That is, the flow velocity will change when the water flows from the vertical pipe to the horizontal pipe, which will easily lead to turbulence and stagnation of the water flow. This discontinuity of flow will cause the water flow to slow down at the corner. Especially when the rainfall is heavy, the impact force of the water flow is not enough to effectively push the rainwater to the downstream drainage system. The existence of the corner also makes it difficult for the water flow to form a smooth flow path, causing rainwater to accumulate at the corner and form water accumulation. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of municipal road drainage device, which is equipped with a square drainage frame and a water collection pipe arranged in parallel at the top and bottom. The square drainage frame and the drainage pipe are connected by the drainage pipe. The primary filtration structure inside the square drainage frame intercepts foreign objects, so that the filtered water flows through the drainage pipe and the secondary filter plate into the water collection pipe. The water that has been doubly filtered enters the subsequently connected water collection pipe, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel municipal road drainage device, comprising a square-mouth drainage frame and a primary filter structure disposed inside the square-mouth drainage frame. A water collection pipe of equal length and parallel arrangement is disposed below the square-mouth drainage frame, and a drainage pipe is installed on one side of the top of the water collection pipe. The top of the drainage pipe is connected to and communicates with the bottom of the square-mouth drainage frame. A secondary filter plate is installed at one end inside the drainage pipe. Square-mouth docking structures are provided at both ends of the square-mouth drainage frame for inserting and connecting the beginning and end ends of two adjacent square-mouth drainage frames.

[0005] Preferably, flanges are installed at both ends of the water collection pipe.

[0006] Preferably, a support is fixed on the upper surface of the water collection pipe on one side of the drain pipe, and the top of the support is connected to the lower surface of the square-mouthed drain frame.

[0007] Preferably, the square-mouth drainage frame, drainage pipe, and water collection pipe are all made of hard plastic components.

[0008] Preferably, the top of the square drainage frame is provided with an upper opening, and an inner edge plate is provided inside the upper opening.

[0009] Preferably, the square opening docking structure includes a rectangular opening at one end of the square opening drainage frame and a rectangular connecting frame integrally formed at the other end of the square opening drainage frame, wherein the rectangular connecting frame and the rectangular opening can be inserted into each other.

[0010] Preferably, the primary filtration structure includes a grid plate overlapping the upper surface of the inner edge plate and a filter frame installed on the lower surface of the grid plate, with a gap provided between the bottom surface of the filter frame and the bottom of the square-mouth drainage frame.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This novel municipal road drainage device, through the close cooperation of a square-mouth docking structure, a square-mouth drainage frame, a primary filtration structure, a drainage pipe, a secondary filter plate, and a water collection pipe, can efficiently collect, filter, and discharge rainwater and accumulated water. The parallel arrangement of the square-mouth drainage frame and water collection pipe avoids multiple bends, ensuring continuous and smooth water flow in the drainage pipe. Especially in cases of heavy rain or sudden precipitation, water can quickly and smoothly flow downstream or into the municipal drainage system through the square-mouth drainage frame and water collection pipe, thus preventing water accumulation due to obstructed flow. The square-mouth drainage frame contains a primary filtration structure, and a secondary filter plate is installed at the bottom of the drainage pipe. These two filtration structures effectively intercept foreign objects in the water flow, such as dead branches, leaves, and garbage, preventing these objects from entering the drainage pipe system. This dual filtration mechanism greatly reduces the risk of drainage pipe blockage, ensuring the long-term stable operation of the drainage pipe. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 The present invention provides an embodiment of a novel municipal road drainage device, comprising a square drainage frame 1 and a primary filter structure 7 disposed inside the square drainage frame 1. A water collection pipe 3 is arranged in parallel and of equal length below the square drainage frame 1, and a drainage pipe 2 is installed on one side of the top of the water collection pipe 3. The top of the drainage pipe 2 is connected to and communicates with the bottom of the square drainage frame 1. A secondary filter plate 201 is installed at one end inside the drainage pipe 2. Square docking structures 6 are provided at both ends of the square drainage frame 1. The square docking structures 6 are used to insert and connect the beginning and end ends of two adjacent square drainage frames 1.

[0020] A support base 4 is fixed on the upper surface of the water collection pipe 3 on one side of the drain pipe 2, and the top of the support base 4 is connected to the lower surface of the square drainage frame 1. Both ends of the water collection pipe 3 are equipped with flanges 301, which allow the beginning and end of adjacent water collection pipes 3 to be bolted together. The support base 4 improves the connection stability of the water collection pipe 3 and the square drainage frame 1. Since the device does not have too many corners, the water flow path is more straight, reducing the impact of water flow on the pipe, thereby improving the pressure resistance and durability of the pipeline.

[0021] The square-mouth drainage frame 1, drainage pipe 2, and water collection pipe 3 are all made of hard plastic components; the square-mouth docking structure 6 includes a rectangular opening 601 set at one end of the square-mouth drainage frame 1 and a rectangular connecting frame 602 integrally formed at the other end of the square-mouth drainage frame 1. The rectangular connecting frame 602 and the rectangular opening 601 can be plugged into each other. When multiple such devices are arranged, the beginning and end ends of two adjacent square-mouth drainage frames 1 are plugged into each other through the rectangular connecting frame 602 and the rectangular opening 601, so that a continuous pipeline structure is formed between multiple square-mouth drainage frames 1.

[0022] The top of the square drainage frame 1 is provided with an upper opening 101, and the interior of the upper opening 101 is provided with an inner edge plate 5. The primary filtration structure 7 includes a grid plate 702 overlapping the upper surface of the inner edge plate 5 and a filter frame 701 installed on the lower surface of the grid plate 702. A gap is provided between the bottom surface of the filter frame 701 and the bottom of the square drainage frame 1. Road surface water flows through the grid plate 702 and enters the filter frame 701. At this time, the grid plate 702 and the filter frame 701 first filter the foreign objects in the water flow, and the filtered rainwater is collected in the square drainage frame 1 and flows into the water collection pipe 3 from the drain pipe 2.

[0023] When the filter frame 701 is assembled with the square-mouth drainage frame 1, the workers connect the filter frame 701 to the upper opening 101 at the top of the square-mouth drainage frame 1, so that the bottom edge of the grid plate 702 rests on the inner edge plate 5. The arrangement of the grid plate 702 and the inner edge plate 5 makes the filter frame 701 suspended, so that foreign objects and water flow can be separated.

[0024] In this embodiment, the drainage device is first installed in the side ditch of a municipal road. The ends of two adjacent square drainage frames 1 are connected by a square-mouth butt joint structure 6, and the ends of two adjacent water collection pipes 3 are bolted together by flanges 301, thus forming a continuous drainage pipeline. When rainwater flows into the square drainage frame 1, the water is guided into the square drainage frame 1 by the primary filtration structure 7. The primary filtration structure 7 ensures smooth water flow and effectively blocks the entry of larger objects. This process not only guarantees the quality of the water flow... It also effectively prevents foreign objects from entering the drainage pipe, reducing the risk of blockage. After primary filtration, the water will be transported downstream through the drain pipe 2 until it enters the collection pipe 3. The drain pipe 2 uses gravity to accelerate the flow of water. Before the water reaches the collection pipe 3, the secondary filter plate 201 can further remove foreign objects in the water flow, ensuring that the water entering the collection pipe 3 is cleaner. The collection pipe 3 and the square drain frame 1 are arranged in parallel vertically. The collection pipe 3 can accommodate a large amount of water flow and guide it to the municipal drainage system or other treatment facilities, so that the water flow is not obstructed during the entire drainage process.
