Description

Technical Field

[0001] This utility model belongs to the technical field of snow removal devices, specifically relating to a device for snow removal on highways. Background Technology

[0002] In northern my country, snowfall is frequent in winter. Snow accumulation on roads significantly reduces the road surface friction coefficient, posing a serious threat to the driving stability of passing vehicles and the safety of pedestrians. Especially on highways, residential roads, and some fixed locations (such as parking lots and sidewalks), if snow is not cleared in time, it can easily cause traffic congestion or safety accidents. Therefore, efficient snow removal on roads in winter has become an important requirement to ensure public travel safety.

[0003] Currently, the main devices and methods for clearing snow from roads on the market include snowplows, wire brushes, de-icing agents, and manual sweeping. However, these existing technical solutions all have significant drawbacks in practical applications: 1. Snowplows and wire brushes: Both are contact snow removal devices, requiring direct contact with the road surface during operation. On the one hand, their snow removal efficiency is relatively low, making it difficult to quickly handle large areas of snow accumulation; on the other hand, the hard contact between the equipment and the road surface can easily cause physical damage to asphalt, cement, and brick pavements, shortening the service life of the road surface and increasing the cost of subsequent road maintenance.

[0004] 2. De-icing agents: The main component of existing de-icing agents is calcium carbonate. Although they can melt snow by lowering the melting point of ice and snow, the residue of de-icing agents can penetrate into the interior of the road structure and corrode the road surface. Long-term use can easily lead to cracking and peeling of the road surface. At the same time, after the snow and ice melt, the de-icing agent seeps into the soil or water bodies, which will also pollute the surrounding ecological environment and does not meet environmental protection requirements.

[0005] 3. Manual snow removal: It is only suitable for narrow roads or special areas that are difficult for mechanical equipment to enter. Its work efficiency is extremely low, the labor intensity is high, and it cannot meet the needs of large-scale and rapid snow removal, making it difficult to cope with emergency snow removal work after sudden snowfall.

[0006] In summary, existing snow removal methods generally suffer from problems such as road surface damage, low operational efficiency, severe environmental pollution, or limited applicability, failing to simultaneously meet the comprehensive needs of snow removal effectiveness, road surface protection, environmental friendliness, and operational flexibility. Therefore, developing a non-contact, efficient, environmentally friendly, and non-damaging road surface snow removal device has become a key direction for solving the current winter road snow removal problem. Utility Model Content

[0007] In view of the technical problems that existing snow removal methods generally suffer from, such as damaging the road surface, low operating efficiency, serious environmental pollution, or limited application scenarios, this utility model provides a device for highway snow removal.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A device for snow removal on highways includes an air supply unit, a fuel unit, a combustion system, and a generator set; The generator set is electrically connected to the fuel pump of the fuel unit, the air supply unit, and the ignition device of the combustion system, respectively, and is used to provide working power to the fuel pump, the air supply unit, and the ignition device. The air supply unit includes a gas delivery pipeline, and the air supply unit is connected to the combustion chamber of the combustion system through the gas delivery pipeline for supplying high-pressure air to the combustion chamber. The fuel unit includes a high-pressure fuel pipe, and the fuel unit is connected to the combustion chamber through the high-pressure fuel pipe for supplying fuel to the combustion chamber. The combustion system includes a combustion chamber and an ignition device. The ignition device is used to ignite a mixture of fuel and high-pressure air in the combustion chamber. After combustion, the mixture produces high-speed, high-pressure, and high-temperature gas. The high-speed, high-pressure, and high-temperature gas is blown out through a nozzle in the combustion chamber to achieve snow melting and snow blowing.

[0009] The air supply unit also includes a control device and a power device; the control device is electrically connected to the power device, and the control device is used to control the start and stop, speed adjustment and overload protection of the power device; the power device is connected to the gas delivery pipeline, and the power device is used to generate high-pressure air and deliver it to the combustion chamber through the gas delivery pipeline.

[0010] The power unit includes an impeller, a volute, a motor housing, a stator, a rotor, a shaft, and bearings. The impeller is mounted on the shaft, and the stator and rotor are assembled inside the motor housing, with the rotor engaging with the shaft. When the impeller rotates at high speed, it generates negative pressure to draw in external gas. The impeller performs work to convert the gas into high-speed, high-pressure gas. The high-speed, high-pressure gas is collected and pressurized by the volute and then ejected from the volute outlet, and transported to the combustion chamber through the gas delivery pipeline.

[0011] The fuel unit also includes a fuel tank and a fuel control system; the fuel tank is connected to the fuel pump and is used to store fuel; the fuel control system is electrically connected to the fuel pump and the air supply unit respectively, and the fuel control system is used to intelligently adjust the fuel injection volume of the fuel pump according to the amount of air delivered to the combustion chamber by the air supply unit.

[0012] The generator set provides three-phase AC power with a frequency of 50Hz and a phase voltage of 220V.

[0013] The fuel control system precisely regulates the amount of fuel injected by adjusting the opening of the valve on the fuel pump to match the airflow entering the combustion chamber, thereby saving energy and fuel.

[0014] The control device adjusts the speed of the power unit by rotating the speed adjustment knob on the operation panel. The speed of the power unit can be adjusted to at least 5400 r / min to adjust the air volume according to the degree of snow accumulation on the road and adapt to the snow removal needs of different scenarios.

[0015] Compared with the prior art, the advantages of this utility model are: 1. This utility model uses a high-speed, high-heat airflow for non-contact snow removal on the road surface. During operation, there is no need for direct contact with the road surface, and the near-ground temperature is strictly controlled below the asphalt softening point. It can be adapted to various road surface types such as asphalt, cement, and blue brick, completely avoiding physical damage to the road surface caused by contact friction of traditional snowplows and wire brushes. At the same time, the device does not require the use of de-icing agents with calcium carbonate as the main component, fundamentally eliminating the corrosive effect of de-icing agents on the road surface and the environmental pollution to soil and water bodies, thus taking into account both road protection and ecological environmental protection needs.

[0016] 2. This utility model delivers high-pressure air to the combustion chamber through an air supply unit. After combustion with fuel, it produces high-speed, high-pressure, and high-temperature gas. The high-temperature airflow can loosen the snow in advance and break the adhesion between the snow and the road surface. Combined with the high-speed airflow, compared with the inefficient mode of traditional snowplows' "push-type snow removal" and wire brushes' "friction sweeping", it can remove snow from the road surface more quickly and thoroughly. It is especially suitable for emergency snow removal scenarios after sudden snowfall in northern winters and can effectively ensure the safety of vehicles and pedestrians.

[0017] 3. This utility model has a precise linkage adjustment mechanism: on the one hand, the fuel control system can intelligently adjust the fuel injection volume of the fuel pump in real time according to the air volume delivered to the combustion chamber by the air supply unit; on the other hand, the control device can change the air volume by adjusting the speed of the power unit, and the operator can match the corresponding air volume according to the actual snow accumulation on the road, avoiding the ineffective consumption of electricity and fuel, significantly reducing the operating cost of the device, and meeting the requirements of energy conservation and consumption reduction.

[0025] This embodiment provides a device for highway snow removal, such as... Figure 1 , 2As shown, generator set 4 provides working power to fuel pump 22 of fuel unit 2, air supply unit 1 and ignition device 32 of combustion system 3, ensuring the start-up and operation of each core component; air supply unit 1 supplies high-pressure air to combustion chamber 31 of combustion system 3 through gas delivery pipeline 13, while fuel unit 2 supplies fuel to combustion chamber 31 through high-pressure fuel pipe 24; ignition device 32 ignites the mixture of fuel and high-pressure air in combustion chamber, and the mixture produces high-speed, high-pressure and high-temperature gas after combustion. This gas is blown out through nozzle of combustion chamber 31, using high temperature characteristics to loosen snow and high speed characteristics to blow away snow, ultimately achieving the purpose of snow removal by melting and blowing snow.

[0026] Furthermore, the control device 11 of the air supply unit 1 is electrically connected to the power unit 12. The control device 11 can regulate the start-stop status, speed, and overload of the power unit 12 to prevent abnormal operation of the power unit 12. The power unit 12 is connected to the gas delivery pipeline 13. Under the regulation of the control device 11, the power unit 12 generates high-pressure air and stably delivers the high-pressure air to the combustion chamber 31 through the gas delivery pipeline 13, providing a sufficient gas source for the mixing and combustion of fuel and air, and ensuring the generation of subsequent high-temperature airflow.

[0027] Furthermore, the impeller of the power unit 12 is mounted on the rotating shaft, and the stator and rotor are assembled inside the motor housing, with the rotor engaging with the rotating shaft. When the power unit 12 is started, the rotating shaft drives the impeller to rotate at high speed. During the rotation of the impeller, a negative pressure is generated, drawing external gas into the power unit 12. Subsequently, the impeller performs work on the drawn-in gas, converting it into high-speed, high-pressure gas. After being collected and pressurized by the volute, the high-speed, high-pressure gas is ejected from the volute outlet and then transported to the combustion chamber 31 through the gas delivery pipeline 13, providing high-pressure air that meets the requirements for the combustion reaction of the combustion system 3.

[0028] Furthermore, the fuel tank 21 of the fuel unit 2 is connected to the fuel pump 22 to store fuel and ensure the continuous delivery of fuel by the fuel pump 22; the fuel control system 23 is connected to the fuel pump 22 and the air supply unit 1 respectively, and can monitor the air volume delivered by the air supply unit 1 to the combustion chamber 31 in real time, and intelligently adjust the fuel injection volume of the fuel pump 22 according to the monitored air volume data to ensure that the fuel volume and air volume are matched, and provide a reasonable fuel supply for efficient combustion.

[0029] Furthermore, generator set 4, as the core power supply of the device, can stably output three-phase AC power with a frequency of 50HZ and a phase voltage of 220V. This specification of AC power can accurately match the power requirements of fuel pump 22, air supply unit 1 and ignition device 32, providing stable and compliant power support for each component, avoiding component failure due to voltage or frequency abnormalities, and ensuring the continuity of the overall snow removal operation of the device.

[0030] Furthermore, the fuel control system 23 achieves precise adjustment of fuel injection quantity by adjusting the opening of the valve on the fuel pump 22; when the air volume delivered to the combustion chamber 31 by the air supply unit 1 changes, the fuel control system 23 adjusts the valve opening synchronously to keep the fuel injection quantity and air volume matched, avoiding waste due to excessive fuel or incomplete combustion due to insufficient fuel, thereby achieving the purpose of saving electricity and fuel.

[0031] Furthermore, the control panel of the control device 11 is equipped with a speed adjustment knob. The operator can adjust the speed of the power unit 12 by rotating the knob, and the speed of the power unit 12 can be adjusted to at least 5400 r / min. In actual operation, the required air volume can be determined according to the degree of snow accumulation on the road, and then the speed of the power unit 12 can be adjusted by the speed adjustment knob to match the corresponding air volume, so that the device can adapt to the snow removal needs of different snow accumulation scenarios and improve the flexibility and targeting of snow removal operations.

[0032] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
