Description

Technical Field

[0001] The utility model belongs to the technical field of snow removal equipment, and particularly relates to a hot-blowing snow removal vehicle. Background Art

[0002] Most mountain roads are built among high mountains and ridges according to natural geographical conditions. In cold seasons, they often encounter harsh weather conditions such as rain, snow, and fog. In severe cases, landslides, mudslides, etc. may occur. The prominent features of mountain roads are high mountains, dense forests, steep slopes, narrow roads, sharp bends, and poor visibility. There are more risks brought by extreme ice and snow weather. Some mountain roads are blocked by altitude and mountains during the ice and snow season, and the snow and ice are difficult to melt for a long time. When such risks occur, mountain roads are often damaged and traffic is interrupted. Therefore, only footpaths and temporary bridges are available for pedestrians to pass, but normal driving is impossible, which seriously affects mountain tourism and various business activities. If a vehicle encounters extremely heavy ice and snow disaster weather and lacks corresponding emergency equipment, once a traffic accident occurs, only the mountain and the road can be closed. If there are casualties in the accident, it will directly bring greater economic losses and social impacts. In order to ensure the safety and smoothness of the road and be able to quickly and effectively handle extreme disasters such as ice and snow, the road maintenance department has high expectations for introducing advanced snow removal equipment.

[0003] However, the existing snow removal vehicles are generally used in environments such as municipalities, highways, and airports in terms of applicable scenarios, and the problem of snow removal on mountain roads with poor road conditions has not been effectively solved.

[0004] The existing snow removal methods mainly have the following disadvantages:

[0005] 1. Mechanical snow removal is not thorough for uneven road surfaces and depressions, cannot remove the ice on the road surface, has low efficiency, and has a small application range for road surfaces.

[0006] 2. The existing hot-blowing snow removal vehicle with an aviation engine has a small ground clearance and approach angle of the whole vehicle, and the vehicle is too long and not suitable for mountain roads with too many slopes and bends.

[0007] 3. The existing hot-blowing snow removal vehicle has too large an exhaust volume for removing ice and snow, and often is equipped with two aviation engines. Because there is a main lateral snow removal nozzle, it is more suitable for snow removal on wide road surfaces such as airport runways. However, there are sand, pedestrians, guardrails, green plants, flowers and plants, etc. on both sides of mountain roads. Direct application is likely to blow and damage the above-mentioned people and objects, and it is easy to cause flying stones and blow them to the lower road section to injure pedestrians. Therefore, a hot-blowing snow removal vehicle does not require too wide a blowing range when used on mountain roads.

[0008] 4. The blowing power of the existing cold-blowing snow removal vehicle mainly relies on the blower, and the wind force is much smaller than that of an aviation engine. The blown air flow is cold air, which is suitable for blowing floating snow and relatively thin snow accumulation, and cannot effectively remove relatively thick snow accumulation and ice layers.

[0009] Therefore, it is very important to develop a new type of snow removal vehicle suitable for mountain roads. Contents of the Utility Model

[0022] Compared with the prior art, the advantages of the present utility model are as follows:

[0023] (1)The utility model discloses a hot-blowing snow removal vehicle. The power carried by this hot-blowing snow removal vehicle for mountain roads is a small turbofan engine, or an aviation turbojet engine can be replaced. Compared with large aviation engines, it has low fuel consumption, low noise, high reliability, and moderate thrust. During the vehicle's travel, the same section of the road surface can be purged twice, and it can remove the ice and relatively thick snow on the 1-2 lane road surface, without damaging roadside facilities and trees, with high operation efficiency, ensuring the safe and reliable operation of mountain roads;

[0024] (2)The utility model selects an automobile chassis with strong maneuverability and good climbing ability, which is more suitable for mountain roads. The wheelbase and the overall vehicle length are shorter. Changing to large snow tires and pneumatic suspension increases the ground clearance of the chassis. The nozzle design has also been newly optimized, and a snow blowing nozzle with a larger approach angle has been designed. After installing the snow blowing nozzle, the approach angle of the vehicle can reach 15-20°;

[0025] (3)This mountain road hot snow blower only uses a single small turbofan engine. In existing hot-blowing snow removal vehicles, usually the nozzle in front of the vehicle head is used as an auxiliary blower, and the rest are the main blower nozzles. However, the utility model has changed the original purging mode and has been redesigned and optimized on the snow blowing nozzle through an arc bifurcation method, removing the side blowing nozzles of traditional jet snow blowers. The purging direction of the nozzle and the distribution ratio of the exhaust flow rate have also been readjusted, and more flow is distributed to the nozzle in front of the vehicle head. Among them, the nozzles in front of the vehicle head are the first front blowing main nozzle and the second front blowing main nozzle, and the nozzles facing inwards in the middle of the vehicle body are the first rear blowing auxiliary nozzle and the second rear blowing auxiliary nozzle.

[0026] (4)Considering economy, volume, and fuel consumption, the utility model preferably selects a small aviation turbofan engine as the snow blowing power and has made certain adapted modifications to it. After starting, the small turbofan engine is used to direct the tail jet flow, and then it is split into 4 special-shaped counter-blowing nozzles according to a certain ratio. The 4 special-shaped counter-blowing nozzles are the first front blowing main nozzle, the second front blowing main nozzle, the first rear blowing auxiliary nozzle, and the second rear blowing auxiliary nozzle to ensure the purging operation of the vehicle. Among them, a new design has also been carried out on the purging pipeline, optimizing the nozzle cross-section and arc transition, making the pipeline streamline smoother, reducing air flow loss, and readjusting the purging direction of the nozzle and the distribution ratio of the exhaust flow rate, and allocating more exhaust flow to the nozzle in front of the vehicle head. Compared with traditional jet snow blowers, the vehicle has a larger approach angle. This utility model guarantees the passage and safety of mountain roads covered with ice and snow, can avoid blowing the gravel or other redundant objects on both sides of mountain roads down the mountain, protects the natural environment of mountainous areas, fills the gap of current domestic hot snow blowers for mountain roads, not only saves the cost of manual snow removal, ensures operation safety, but also improves efficiency.

[0068] Working principle of the present utility model:

[0069] When the present utility model is working, after reaching the designated operation area, the operator of the hot-blowing snow removal vehicle starts the turbofan engine 4, and the external air is output to the exhaust device 5 after passing through the intake device 2 and being heated and doing work by the ignition combustion of the engine.

[0070] The small turbofan engine and the new-shaped special air duct equipped with the present utility model are more suitable for mountain roads, solving the problems of limited applicable roads of current domestic and foreign similar equipment, too wide blowing surface of the operation road, and easy damage to roadside facilities. Through the selection of the chassis type and the optimized improvement design of the snow-blowing nozzle, the road passability of the snow removal vehicle is improved, the safety of the blowing operation is guaranteed, and the mountain ecological environment is maintained.

In case of thick ice and snow, the hot air flow ejected from the first rear blowing auxiliary nozzle and the second rear blowing auxiliary nozzle performs secondary blowing on the stubborn snow and ice that have not been cleared by the first front blowing main nozzle and the second front blowing main nozzle, which further ensures the effective blowing and clearing of the snow, ice and other debris on the driving road surface to a greater extent. During operation, according to the specific conditions of the snow and ice on the road surface, the driver can adjust the working state of the engine on the control screen to change the jet flow rate to achieve the best snow blowing and ice removing effect, which not only realizes efficient snow removal but also reduces energy consumption.
