Description

Technical Field

[0001] This invention relates to the technical field of road maintenance machinery and equipment, specifically to an intelligent emergency maintenance disaster prevention device and method based on the rapid recovery of road surface anti-skid performance. Background Technology

[0002] With the continuous expansion of my country's highway network, especially its extension into high-altitude, snowy regions, winter road icing and snow problems have become a significant factor affecting traffic safety, traffic efficiency, and socio-economic operations. According to incomplete statistics, traffic accidents caused by ice and snow account for more than 30% of all winter traffic accidents in my country each year. Traditional methods such as manual snow removal and mechanical snowplowing are no longer sufficient to meet the demands of modern traffic maintenance for rapid response and efficient clearing.

[0003] Currently, de-icing agent spreaders have become the main equipment for winter road maintenance. Their working principle is mainly to mechanically spread solid or liquid de-icing agents onto the road surface, utilizing the physicochemical properties of the agents to lower the freezing point and accelerate snow and ice melting. However, existing equipment still suffers from problems in practical applications, such as poor spreading uniformity, low material utilization, insufficient operational intelligence, easy equipment clogging, and environmental pollution. Especially in emergency maintenance scenarios involving large areas, long road sections, and sudden snowfall, existing equipment lags behind in terms of operational efficiency, precise control, and environmental friendliness, failing to meet the modern maintenance requirements of "rapid response, precise operation, and green efficiency."

[0004] Existing technical solutions and their disadvantages Currently, de-icing agent spreading equipment on the market is mainly divided into two categories: mechanical spreading type and liquid spraying type, and they generally have the following technical defects: 1. The level of intelligent operation control is low, making it difficult to guarantee the uniformity and coverage of the spreading. Most existing equipment relies on manual operation based on experience, and parameters such as feeding rate, spreading width, and spreading angle cannot be dynamically adjusted in real time. Uneven spreading is prone to occur during vehicle start-up, stopping, and speed changes, resulting in "strip" or "zebra" patterns. In addition, traditional mechanical spreading or fixed spray booms have relatively fixed spreading width and density distributions, causing a "spreading shadow zone" to form directly below the feeder due to mechanical structure, resulting in uncovered strips, affecting snow melting effect and causing material waste.

[0005] 2. The pavement behavior of solid particulate materials is uncontrollable, resulting in low effective utilization. Solid de-icing agent granules are prone to bouncing, rolling, and being blown away by the wind during application, resulting in a large amount of material leaving the target area. This leads to insufficient effective dosage on the road surface, causing not only economic losses but also pollution of the soil and water bodies along the road. A large amount of de-icing agent granules detach from the intended application area and accumulate on the curb or median strip, significantly reducing the effective dosage that actually makes close contact with the snow and ice layer. Especially in strong winds, lighter granules are blown away, causing material drift and pollution along the roadside, and severely affecting the accuracy of application, making it impossible to achieve targeted delivery. All these factors combined result in a low initial adhesion rate of solid granules to the target road surface, with a large amount of material failing to remain on the snow and ice to be treated, causing direct economic losses and environmental burden.

[0006] 3. Solid de-icing agents have a delayed mechanism of action, which cannot meet the needs of rapid emergency response. From a mechanistic perspective, solid chloride-based de-icing agents must first absorb moisture (from the air or the surface of ice and snow) and deliquesce into a solution before they can lower their freezing point through osmotic pressure. This "hygroscopic-dissolving-onset" process has a significant time delay. In emergency situations (such as sudden snowfall or rapid road icing), this lag means that there is still a dangerous "effectiveness window" after application, making it impossible to achieve instant ice prevention or rapid snow melting, which is insufficient for application scenarios with extremely high requirements for road traffic safety response speed. Solid chloride-based de-icing agents require a "hygroscopic-dissolving-penetrating" process to exert their ice-melting effect, resulting in a significant "onset delay," making it impossible to provide immediate protection in the early stages of icing or during sudden snowfall, thus affecting emergency response efficiency.

[0007] 4. The storage and conveying system has poor anti-caking ability and low equipment reliability. De-icing agents, especially highly hygroscopic varieties such as calcium chloride and magnesium chloride, are prone to becoming damp and sticking to the equipment walls in storage tanks and conveying systems. This can lead to problems such as poor material discharge, screw jamming, and clogging of the spreading disc, seriously affecting the continuous operation capacity and spreading quality of the equipment.

[0008] Most current equipment has a simple design for its hoppers or storage bins, focusing only on storage and generally lacking proactive and effective anti-adhesion intervention measures. This adhesion can clog the discharge port, causing interruptions or intermittent feeding, directly resulting in a chaotic particle size distribution of the material finally spread on the road surface. This severely damages the uniformity of spreading and the controllability of dosage, making refined and scientific operations impossible. Summary of the Invention

[0009] The purpose of this invention is to provide an intelligent emergency maintenance and disaster prevention device and method based on rapid recovery of road surface anti-skid performance, in order to solve the technical problems mentioned in the background art.

[0010] The technical solution of the present invention is as follows: A smart emergency maintenance and disaster prevention device based on rapid recovery of road surface anti-skid performance adopts a dual high-pressure air delivery coordinated device. The device includes a power system, a solid-core liquid-shell composite particle preparation unit, which forms a solid-core liquid-shell structure through solid-liquid mixing; a full-process high-pressure airflow unblocking module, which destroys the material arch bridge structure through high-pressure airflow; an outer cover structure of a spiral feeder with air holes, which isolates the material from the metal wall through an air cushion membrane; and also includes an intelligent control system, a linkage control system and a liquid spraying system. The dual high-pressure air delivery coordinated device includes a high-pressure blower (2) and an air delivery pipe (3), which delivers airflow to the high-pressure air delivery distributor (9).

[0011] The symmetrical arrangement of centrifugal fan units and their linkage control achieve an air delivery area overlap rate of ≥30%, eliminating the unevenness problem caused by the "shaded area" in traditional equipment and ensuring uniform coverage of the road surface by snow melting / anti-skid materials. The solid-core liquid-shell composite particle preparation unit forms a "solid-core liquid-shell" structure through solid-liquid mixing, solving the problems of "bouncing / wind-blown" and "delayed onset" of solid snow melting agents, and improving material adhesion efficiency and reaction speed. The full-process high-pressure airflow unblocking module breaks the material arch structure with high-pressure airflow, solving the problem of adhesion and blockage of hygroscopic snow melting agents in the storage / transportation system, and ensuring continuous material transportation. The vented screw feeder outer cover structure: isolates the material from the metal wall through an air cushion membrane, eliminating the problem of reduced transportation efficiency caused by "wall hanging" and improving transportation efficiency. The intelligent control system: integrates multiple sensors to achieve dynamic matching of "vehicle speed-flow rate-width-concentration", improving operation efficiency and safety.

[0012] Furthermore, it also includes: a solid core preparation module, which uses high-density snow-melting agent particles as the core to ensure the stability of the core material and the snow-melting effect; a liquid shell coating module, which forms a uniform liquid shell by controlling surface tension to improve the coating uniformity and overall material performance; and a curing and molding device, which ensures the stability of the shell structure by using low-temperature curing technology to prevent shell cracking or performance degradation.

[0013] Furthermore, it also includes: a high-pressure airflow injection unit for the storage silo, with an annular airflow nozzle installed at the material inlet to directly impact the material arch structure and prevent adhesion and blockage; a conveying pipeline unblocking unit, with pulse airflow generators arranged along the conveying path, the pulse frequency of the pulse airflow generators being 5-50Hz and the air pressure being 0.2-1.0MPa, continuously removing adhered materials in the pipeline through pulse airflow; and an end anti-blocking unit, with a rotating airflow unblocking device installed at the discharge port to prevent blockage at the discharge port and ensure smooth material discharge.

[0014] Furthermore, it also includes: a micropore array on the surface of the spiral blades, with a pore size ranging from 0.1 to 1 mm, allowing low-pressure airflow to pass through and form an air cushion film; an air cushion film generating device, which forms a continuous air cushion between the material and the metal wall through low-pressure airflow, isolating the material from contact with the metal wall; and a dynamic pressure monitoring module, which adjusts the air cushion thickness in real time to the optimal conveying state, maintaining efficient conveying and preventing wall adhesion.

[0015] Furthermore, it also includes: a lidar vehicle speed monitoring module with an accuracy of ±0.1km / h, which monitors vehicle speed in real time and provides data support for dynamic matching; a real-time flow regulating valve group with a response time of ≤50ms, which quickly adjusts material flow to adapt to real-time needs; a width adaptive adjustment mechanism that uses a servo motor to drive a variable-amplitude nozzle to dynamically adjust the spreading width and improve coverage uniformity; and a concentration feedback module that uses infrared spectral analysis to achieve real-time concentration calibration to ensure accurate spreading concentration.

[0016] Furthermore, it also includes: using symmetrically arranged centrifugal fan units with a single unit air volume ≥5000m³ / h and air pressure ≥10kPa, and achieving an air supply area overlap rate ≥30% through linkage control to ensure air supply uniformity and coverage effect.

[0017] Furthermore, it also includes: a master-slave controller architecture, where the master controller is responsible for global parameter matching and the slave controller performs local adjustments to achieve coordinated system control; a fault redundancy module, which automatically switches to single-side enhancement mode when a single-side wind-blown system fails to ensure continuous system operation; and a remote monitoring interface that supports 5G / BeiDou dual-mode communication to achieve remote parameter adjustment, improving system maintainability and remote control capabilities.

[0018] Furthermore, the liquid shell contains antifreeze, surfactant and slow-release agent, and achieves stability at -30°C through rheological optimization, ensuring good performance even at low temperatures.

[0019] Furthermore, the pulse airflow generator is controlled by an array of electromagnetic valves, with an adjustable pulse frequency range of 5-50Hz and an air pressure adjustment range of 0.2-1.0MPa, precisely controlling airflow parameters and effectively clearing adhesion and blockage.

[0020] A method for using the aforementioned intelligent emergency maintenance and disaster prevention device based on rapid recovery of road surface anti-skid performance includes the following steps: S1: Real-time vehicle speed, road surface temperature, and humidity parameters are collected through the intelligent control system; S2: Dynamically adjust the preparation ratio and delivery flow rate of solid-core liquid-shell composite particles according to parameters; S3: Activate the dual high-pressure air delivery collaborative architecture to achieve cross-coverage of the air delivery area; S4: Continuously monitor and remove adhesive blockages in the storage / conveying system through the full-process high-pressure airflow unblocking module; S5: Maintains optimal conveying efficiency by utilizing the outer casing structure of the screw feeder with air holes; S6: Through the intelligent control system, the matching parameters of "vehicle speed-flow rate-width-concentration" are continuously optimized to achieve rapid recovery of road surface anti-skid performance and disaster prevention.

[0021] By collecting real-time parameters, dynamically adjusting the preparation ratio and delivery flow rate, activating the dual high-pressure air delivery collaborative architecture, continuously monitoring and clearing adhesion blockages, maintaining optimal delivery efficiency, and continuously optimizing matching parameters, the system achieves rapid recovery of road surface anti-skid performance and disaster prevention, ensuring the effective operation and effectiveness of the entire device.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention creatively proposes and adopts a dual high-pressure pneumatic conveying and distributing structure. Specifically, two independently controllable high-pressure pneumatic conveying systems are symmetrically arranged along the working width. Each system includes a high-pressure blower, air duct, and a controllable distributor with an air outlet. The two systems are not simply connected in parallel, but are linked through a central intelligent control system, enabling synchronous, asynchronous, or differential air delivery. This invention, through the symmetrical staggered arrangement of the two distributors, allows their efficient air delivery zones and distribution ranges to overlap and complement each other. When material is distributed to the two distributors by the screw feeder, the two high-pressure gas-solid two-phase flows generated form a cross-coverage in space, completely filling the blank area below a single distributor, achieving continuous and uniform material coverage from the vehicle's centerline to both side edges.

[0023] 2. This invention employs two liquid spraying devices, one before and one after the dual high-pressure pneumatic conveyor spreader, to spray liquid de-icing agent. When the machine starts operating, the solid and liquid de-icing agents rapidly mix and coat each other upon spraying, forming "solid core, liquid shell" composite particles. This improves road surface adhesion, suppresses dust, and accelerates snow melting. This process fundamentally eliminates the unavoidable dust problem associated with dry spreading, significantly improves air quality in the work area, reduces pollution to the surrounding environment, and embodies the concept of green operations.

[0024] 3. This invention innovatively introduces a full-process high-pressure airflow unblocking and auxiliary conveying system. High-pressure gas injection ports are set in the inlet section, shell, and inside the high-pressure pneumatic conveyor of the screw feeder. The continuously injected high-pressure airflow can fluidize and disturb the material on the screw blades, destroying the initial arch structure and blowing away any sticky or clump-like material. This ensures that the screw can continuously and stably grasp and convey material, fundamentally preventing "bridging" and blockage at the conveying source. Another route of high-pressure gas is directly introduced into the air duct of the high-pressure pneumatic conveyor, mixing with the solid material from the screw feeder. This powerful airflow not only performs the main function of conveying material but also continuously and positively blows through the inside of the conveyor and the outlet, preventing damp material from accumulating, adhering, or even hardening and blocking at the outlet edge, ensuring that the outlet channel is always unobstructed.

[0025] 4. This invention creatively proposes a vented screw feeder outer casing component to solve the problem of screw feeder clogging. This invention features a structural innovation in the outer casing of the core conveying component—the screw feeder—designing a unique "vented screw feeder outer casing" to achieve active anti-sticking on the wall surface. The outer casing has regularly arranged micro-pores or slits in the area corresponding to the gap between the inner wall and the screw blades. Part of the dry gas from the high-pressure blower seeps evenly from these pores through the built-in cavity, forming a stable "air cushion film" or "air curtain" on the inner wall surface of the screw casing, fundamentally solving the problem of material "hanging on the wall" and adhesion. This micro-airflow barrier effectively blocks direct contact between moist de-icing agent particles and the metal casing wall, greatly reducing the possibility of material adhering and accumulating on the wall surface due to moisture absorption, thus solving the "hanging on the wall" phenomenon of materials during the conveying process at a microscopic level.

It is equipped with low-temperature resistant engine oil (starting at -45℃) and adopts a modular maintenance design. The fault repair time is ≤1.5 hours. The engine drives the high-pressure blower (2), screw feeder (6) and liquid controller (11) through belt drive. The transmission ratio is optimized to 1:3.2 to ensure synchronous operation.

[0033] Dual high-pressure air delivery collaborative architecture: The high-pressure blower (2) adopts a symmetrical arrangement of two centrifugal blowers, with a single unit flow rate of 6000 m³ / h and an air pressure of 12.5 kPa. It is connected to the high-pressure air delivery distributor (9) through a φ350 mm air delivery pipe (3). The air delivery pipe is made of Q345B seamless steel pipe, and the flange at the interface is reinforced and equipped with a fluororubber sealing gasket to ensure no leakage in the -40℃ environment. The two blowers are linked and controlled by a master-slave controller, and the air delivery area overlap rate is 38%, which completely eliminates the "spreading shadow area" of traditional equipment.

[0034] Solid-core liquid-shell composite particle preparation unit: Both the storage tank (5) and the liquid storage tank (4) are made of 316L stainless steel, with the inner wall coated with a nano-ceramic anti-stick coating. The solid core preparation module feeds high-density de-icing agent particles (3mm in diameter) into the mixing chamber, and the liquid shell coating module sprays a mixture of antifreeze, surfactant, and slow-release agent through surface tension control. The mixture is then cured at -3℃ by a curing device to form a solid-core liquid-shell structure. According to actual measurements, the adhesion rate is increased by 38%, and the effective time is shortened to 12 minutes.

[0035] II. Implementation Details of Key Components The entire process utilizes a high-pressure airflow unblocking module: The high-pressure airflow injection unit in the storage silo features an annular airflow nozzle at the material inlet, with a spray angle of 45° and an air pressure of 0.7MPa, directly impacting the material's arch structure. The conveying pipeline unblocking unit arranges pulse airflow generators along the φ250mm conveying pipe, controlled by an array of solenoid valves, with a pulse frequency of 30Hz and an air pressure of 0.9MPa, effectively removing adhering materials.

A 0.3mm thick air cushion film is formed by low-pressure airflow (0.12MPa) to isolate the material from the metal wall. The dynamic pressure monitoring module adopts a high-precision pressure sensor to monitor the air cushion pressure in real time and adjust it to the optimal conveying state through PID algorithm.

[0037] Liquid spraying system: The liquid spraying device (7) is a φ60mm long pipe structure, made of duplex stainless steel 2205, and its corrosion resistance meets the requirements of 1200 hours of salt spray test. The liquid controller (11) adopts a Coriolis mass flow meter with a control accuracy of ±0.5%, and is used in conjunction with an infrared spectral concentration feedback module to achieve real-time concentration calibration.

[0038] III. Implementation of Intelligent Control System The lidar vehicle speed monitoring module has an accuracy of ±0.05 km / h and provides real-time vehicle speed feedback to the main controller. The real-time flow control valve assembly has a response time of 25 ms, and the adaptive amplitude adjustment mechanism uses a servo motor to drive a variable amplitude nozzle, with an adjustment range of 2.5-5.5 m. The concentration feedback module uses near-infrared spectroscopy analysis, with a calibration time of ≤1.5 seconds.

[0039] The linkage control system uses a Siemens S7-1500 PLC, with a master-slave controller architecture to achieve global parameter matching and local adjustment. When the fault redundancy module detects a failure in one side of the air supply system, it automatically switches to a single-side enhancement mode to ensure continuous system operation. The remote monitoring interface supports 5G / BeiDou dual-mode communication, enabling remote parameter adjustment and fault diagnosis.

[0040] IV. Usage Method and Implementation Process S1: The intelligent control system collects real-time parameters such as vehicle speed (35km / h), road surface temperature (-8℃), and humidity (90%). S2: Dynamically adjust the preparation ratio of solid-core liquid-shell composite particles to a solid-liquid ratio of 1.2:1 and a conveying flow rate of 2.8 kg / s; S3: Activate the dual high-pressure air delivery collaborative architecture, with two fans operating synchronously to achieve cross-coverage of the air delivery area; S4: The full-process high-pressure airflow unblocking module continuously monitors and removes adhesive blockages in the storage / conveying system, and the pulse airflow generator is activated every 10 minutes for preventative unblocking. S5: The outer casing structure of the screw feeder with air holes maintains an air cushion membrane thickness of 0.25mm, ensuring a conveying efficiency of ≥95%; S6: The intelligent control system continuously optimizes the matching parameters of "vehicle speed-flow rate-width-concentration" and realizes rapid recovery of road surface anti-skid performance through closed-loop control. According to actual tests, the road surface friction coefficient increased from 0.35 to 0.65 after the operation, which fully meets the requirements for safe driving.

[0041] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application.
