Description

Technical Field

[0001] This utility model relates to the field of road design auxiliary equipment technology, and in particular to an auxiliary model for road design. Background Technology

[0002] In the field of municipal road and highway engineering design, road drainage capacity is one of the core indicators affecting road service life, traffic safety, and operation and maintenance costs. With the acceleration of urbanization and the frequent occurrence of extreme rainfall, problems such as road surface flooding and roadbed water damage caused by unreasonable drainage design are becoming increasingly prominent. During the design phase, auxiliary models are needed to simulate real-world scenarios, assess road drainage performance in advance, and optimize drainage structural parameters such as slope, drainage outlet layout, and pavement materials. However, existing road design auxiliary models mostly focus on road structure display or static splicing, making it difficult to meet the needs of dynamic drainage performance testing. This leads to deviations between the design scheme and actual working conditions, increasing the risk and cost of later modifications. For example, a Chinese patent proposes an auxiliary model for municipal road structure design, patent publication number CN219320958U. This patent uses a fixed base plate, supporting cross plates, and strip-shaped limiting grooves to disassemble the road model into several interconnected road surface connectors. The connecting structure at the bottom of the supporting columns enables the detachable installation of these connectors. Simultaneously, the limiting mechanism enhances the overall stability of the model. This patent allows for convenient assembly of different road structures, and the detachable design makes the model reusable, reducing the cost of model production for each design. However, this patent only addresses the issue of "static structure assembly and reuse" of the road model. It does not address the dynamic simulation and testing of road drainage capacity. It cannot simulate natural rainfall scenarios, adjust road slope, measure drainage volume, or compare the drainage efficiency differences of different road surface materials and drainage structures. Therefore, it is difficult to support designers in optimizing road drainage systems and cannot meet the core requirement of modern road engineering for "pre-verification of drainage performance."

[0003] Therefore, we propose an auxiliary model for road design to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary model for road design, which solves the problems in the existing road design auxiliary models that are difficult to dynamically simulate rainfall and road slope, and cannot test and compare the drainage performance of different schemes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary model for road design includes a shell, with an arc-shaped transparent plate mounted on the top of the shell, and further includes: A spray pipe is installed at the top inside the shell; The inside of the shell is equipped with a collection tank, and a set of swing structures are installed on both sides of the top of the collection tank; The top of the collection tank is connected to a set of road models via two sets of swing structures.

[0006] Preferably, a diamond-shaped mesh is installed at the top of the inside of the collection tank, and a water pipe connector is installed on one side of the bottom of the collection tank. The other end of the water pipe connector extends through one side of the collection tank and is fixedly connected to a water pump via a pipeline.

[0007] Preferably, the other end of the water pump extends into the interior of the housing through a pipeline and is fixedly connected to the spray pipe.

[0008] Preferably, the swing structure includes a lower connecting seat, a half-stroke worm gear, an upper connecting seat, and a limiting slide bar.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-5 An auxiliary model for road design includes a housing 1, with an arc-shaped transparent plate mounted on the top of the housing 1, and further includes: A spray pipe 3 is installed at the top inside the housing 1; The inside of the housing 1 is equipped with a collection tank 5, and a set of swing structures 8 are respectively installed on both sides of the top of the collection tank 5; The top of the collection tank 5 is connected to a set of road models 2 by two sets of swing structures 8.

[0018] Furthermore, a diamond-shaped mesh 7 is installed at the top of the inside of the collection tank 5, and a water pipe connector 6 is installed on one side of the bottom of the collection tank 5. The other end of the water pipe connector 6 extends through one side of the collection tank 5 and is fixedly connected to the water pump 4 via a pipeline. The diamond mesh 7 can filter the rainwater dripping from the road model 2, effectively intercepting simulated aggregates and impurities that may fall off the surface of the road surface template 10, preventing them from entering the water pipe connector 6 and the water pump 4 with the water flow, preventing pipeline blockage or impeller wear of the water pump 4, significantly extending the service life of the device's water circulation system, and reducing maintenance frequency and cost. The collection tank 5 can collect the rainwater discharged from the drain pipe 12. With the sealed connection of the water pipe connector 6, it ensures that the rainwater is introduced into the subsequent pipeline without leakage or residue, ensuring the stability of the water volume of the water circulation system and avoiding fluctuations in the spray intensity of the spray pipe 3 due to rainwater loss. This structure provides a key receiving link for the water circulation closed loop, allowing rainwater to be collected and filtered and then directly returned to the spray pipe 3 through the water pump 4 without the need for additional water supply. This saves water resources and can simulate the real scenario of "continuous rainfall", meeting the needs of long-term continuous testing and improving the consistency and reliability of test data.

[0019] Furthermore, the other end of the water pump 4 extends into the interior of the housing 1 through a pipeline and is fixedly connected to the spray pipe 3 to realize the recycling of rainwater. Compared with the design of "directly discharging rainwater after a single rainfall", there is no need to frequently replenish the device with new water, which greatly reduces water consumption during the test process and conforms to the concept of green testing. It is especially suitable for high-frequency test scenarios in the laboratory. The water pump 4 can stably control the water pressure and flow rate, so that the rainwater entering the spray pipe 3 maintains a uniform and constant output state, avoids water pressure fluctuations caused by natural water replenishment, and ensures that the "rainfall amount" and "rainfall intensity" simulated by the spray pipe 3 are highly consistent with the actual test requirements. This reduces test errors caused by spray instability, improves the accuracy of road drainage capacity test data, and provides a more reliable reference for road design.

[0020] Furthermore, the swing structure 8 includes a lower connecting seat 13, a half-stroke worm gear 14, an upper connecting seat 15, and a limiting slide bar 18. Two sets of lower connecting seats 13 are fixedly installed at the top of the collection tank 5, and a half-stroke worm gear 14 is fixedly installed at the middle of the top of the lower connecting seat 13. A set of sliding grooves is installed on each side of the lower connecting seat 13, and a limiting slide rod 18 is slidably installed in the two sets of sliding grooves. The top ends of the two sets of limiting slide rods 18 are fixedly installed together with the upper connecting seat 15. The half-stroke worm gear 14 at the top of the lower connecting seat 13 provides the core transmission basis for angle adjustment. Its arc-shaped tooth surface design can precisely control the rotation angle. With the linkage of the upper connecting seat 15, it ensures that the tilt angle of the road model 2 can be stably kept at the target value, such as the actual road slope range of 0.3%-5%, to avoid angle deviation due to structural loosening. The sliding grooves on both sides of the lower connecting seat 13 and the limiting slide rods 18 constitute The sliding guide structure allows the limiting slide rod 18 to slide synchronously along the slide groove when the road model 2 swings with the upper connecting seat 15. This limits the swing direction of the upper connecting seat 15, preventing it from shifting or swaying. It ensures that the road model 2 remains stable in the horizontal direction when tilted, avoiding changes in the rainwater flow path due to model displacement, which could affect the drainage test results. The structure adopts a modular design, with the lower connecting seat 13 and the collection tank 5, and the upper connecting seat 15 and the road model 2 being fixedly installed. This makes assembly convenient and the structure has high strength, capable of withstanding the weight of the road model 2 and the impact of rainwater, making it suitable for long-term repeated use.

[0021] Furthermore, a worm 16 is rotatably mounted on one side of the upper connecting seat 15 corresponding to the half-stroke worm wheel 14, and a motor 17 is fixedly mounted on one side of the worm 16. The output shaft of motor 17 is fixedly installed together with worm gear 16, and worm gear 16 is meshed with half-stroke worm wheel 14. Compared with the manual adjustment structure, motor 17 can provide stable driving force. With the deceleration transmission of worm gear 16 and half-stroke worm wheel 14, it can meet the needs of different road designs for slope simulation, such as the accurate distinction between 0.3% for urban roads and 2% for highways. Through the forward and reverse control of motor 17, the tilt angle of road model 2 can be quickly switched without manual disassembly or prying of the model, shortening the test preparation time and improving the efficiency of multiple sets of comparative tests.

[0022] Furthermore, the road model 2 includes a base 9, a road surface template 10, a drain outlet 11, and a drain pipe 12. The top of the upper connecting seat 15 is fixedly installed with the base 9, and the road surface template 10 is installed inside the base 9. Three sets of drainage outlets 11 are provided on both sides of the top of the road surface template 10, and a set of drainage pipes 12 are fixedly installed at the bottom of the road surface template 10 corresponding to the three sets of drainage outlets 11 on both sides. The other ends of both sets of drainage pipes 12 are fixedly extended to the bottom of the base 9. The base 9 provides stable support for the road surface template 10. At the same time, different materials and structures of the road surface template 10 can be replaced according to the test requirements, such as asphalt template, permeable concrete template, and template with curb stones, without replacing the entire road model, thus improving the versatility of the device. It can meet diverse test requirements such as "comparison of drainage capacity of different road surface materials" and "testing of drainage effect of different road structures". The three sets of drainage outlets 11 on both sides of the top of the road surface template 10 can simulate the drainage structure of the actual road such as "edge drainage channel" and "shoulder drainage hole", so that the flow path and water collection process of rainwater on the surface of the road surface template 10 are consistent with the height of the real road, avoiding the distortion of the test scene due to unreasonable drainage outlet design. The drainage pipes 12 set at the bottom of the road surface template 10 corresponding to the drainage outlets 11 can directly guide the rainwater discharged from the drainage outlets 11 into the collection tank 5, realizing the measurement of "total drainage of a single road model" and "drainage per unit time".

[0023] In summary: The device works by simulating and testing road drainage scenarios through the precise linkage of its components: First, the starter motor 17 drives the worm gear 16 to rotate. Because the worm gear 16 meshes with the half-stroke worm wheel 14, the upper connecting seat 15 tilts and swings around the half-stroke worm wheel 14 as a fulcrum. At the same time, the limiting slide rod 18 at the bottom of the upper connecting seat 15 slides along the groove of the lower connecting seat 13 to limit the swing direction. Ultimately, this causes the road model 2 to present a preset tilt angle, such as 0.3%-5%, simulating different road slopes. Then, the water pump 4 is started to draw water from the water pipe joint 6 of the collection tank 5, pressurizes it, and delivers it to the spray pipe 3. The spray pipe 3 sprays the water evenly. Rainwater is sprayed onto the surface of the road surface template 10 of the road model 2. By adjusting the power of the water pump 4, different intensities of rainfall can be simulated. After the rainwater falls on the road surface template 10, it flows along the inclined slope, flows into the drainage pipe 12 through the drain outlets 11 on both sides of the top, and then drips from the base 9 into the collection tank 5. This process simulates the drainage of actual roads and can measure the drainage volume of a single model. After the rainwater falls into the collection tank 5, it is filtered for impurities by the diamond mesh 7 and then pumped by the water pump 4 to the spray pipe 3, forming a closed-loop water cycle. This saves water resources and ensures continuous and stable spraying, ultimately enabling the testing and comparative evaluation of the drainage capacity of roads with different slopes and road surface designs.
