Guardrail cleaning vehicle capable of comprehensively utilizing thermal power

Abstract

The invention discloses a guardrail cleaning vehicle capable of comprehensively utilizing thermal power. The vehicle comprises a vehicle body, an engine and a guardrail cleaning device and is characterized in that the vehicle body is provided with a warm air anti-icing device, the warm air anti-icing device comprises a compressor and a warm air pipeline, a compressor pipe is connected with a warmair condenser, a throttle device and an evaporator, the warm air condenser is arranged in the warm air pipeline, and air blowing ports of the warm air pipeline are located in the side edges of cleaning rollers. According to the vehicle, the engine is adopted for driving the compressor, the compressor can absorb heat energy in air for hot air icing prevention, wherein the heat energy in the air is4.5 times mechanical energy output by the engine; the heat energy of the engine can be recycled, heat finally obtained by using fuel in the vehicle for work making far exceeds multiple times heat released by pure combustion of the fuel, and the vehicle is more environmentally friendly and saves more energy.

Description

technical field [0001] The invention relates to the field of road sweeper equipment, in particular to a guardrail cleaning vehicle for comprehensive utilization of heat. Background technique [0002] In order to maintain the traffic order and traffic safety of vehicles and pedestrians, guardrails are generally installed on roads in cities and towns, generally in the middle and on both sides of the road. Due to the influence of road pollution and dust, a lot of dust and stains will adhere to the guardrail, which not only reduces the overall image of the city, affects the beauty of the road, but also accelerates the corrosion of the guardrail, especially the iron guardrail is more likely to rust. Therefore, it is necessary to maintain and clean the guardrail regularly. At present, the guardrail cleaning mode is mainly divided into manual cleaning mode and mechanized cleaning mode. The mechanized cleaning mode has the advantages of high cleaning efficiency, good cleaning effect...

AI Technical Summary

Problems solved by technology

[0003] At present, all guardrail cleaning vehicles on the market need to be cleaned by spraying water. However, in the cold winter in northern my country, the temperature is generally lower than 0°C, and the guardrail and ground temperature are lower than the freezing temperature of water, which will cause the sprayed water to be sprayed quickly. Freezing, ice slag and cleaning rollers are frozen together, unable to work normally, and, even if the temperature is slightly higher than the freezing temperature during the day, the temperature will drop below 0°C at night, and the water sprayed from the cleaning guardrail will flow on the ground , Freezing in the cold night, uneven icing on the road surface is not easy to attract the driver's attention, and it is more likely to cause the vehicle to slip or even overturn during driving, which significantly increases the risk of road driving

[0004] Therefore, in the winter in northern my country, the existing guardrail cleaning vehicles cannot be used normally.
