Description

Technical Field

[0001] The utility model relates to the technical field of hot air snow removal vehicles, in particular to an aviation fuel tank and a fuel supply monitoring system of a hot air snow removal vehicle. Background Art

[0002] At present, most of the snow removal operations for airport runways and expressways in northern China are carried out by mechanical snow removal vehicles, which have low snow removal efficiency and long time, and do not meet the requirements of disaster prevention and opening time limits for airports and expressways. Some airports and expressways have adopted hot air snow removal vehicles for efficient snow removal operations. The latter has improved the snow removal efficiency and reduced the operation time. At present, most of the supporting equipment of the primary fuel supply system for snow removal vehicles are products of the last century, far behind the current technical standards (only the fuel level in the aviation fuel tank is displayed), and cannot realize the digital monitoring of the whole system. The collected monitoring data cannot be communicated and exchanged with the vehicle-mounted automatic control system, and cannot realize the mechatronic management; moreover, there is no special fire prevention and heat insulation setting for the aviation fuel tank, and it cannot effectively and quickly isolate the external fire. Since the external fire is very easy to ignite the fuel stored in the aviation fuel tank and make the fire develop rapidly (the vehicle carries nearly 4000-7000 kg of aviation fuel), the safety of the surrounding area cannot be guaranteed within a certain period of time. There is no special mobile fire extinguishing facility (system) installed for the aviation fuel tank, and when a fire occurs outside the aviation fuel tank and threatens the safety of the fuel stored in the tank, it cannot effectively protect the fuel tank and extinguish the fire inside. Therefore, we propose a new aviation fuel tank and fuel supply monitoring system for hot air snow removal vehicles. Content of the Utility Model

[0003] The main purpose of the utility model is to provide an aviation fuel tank and a fuel supply monitoring system for a hot air snow removal vehicle, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] The aviation fuel tank of the hot-blowing snow removal vehicle comprises a box body formed by welding a metal box body outer wall and a metal steel frame assembly, wherein two metal transverse partitions and a metal longitudinal partition are welded in the box body through the metal box body outer wall and the metal steel frame assembly, an aviation fuel tank manhole is arranged at the right part of the upper end of the box body, two submersible oil pump installation ports are opened on the aviation fuel tank manhole, and the aviation fuel tank manhole is equipped with a sealing cover, an aviation fuel tank measurement installation hole and an aviation fuel tank ventilation installation hole are arranged at the front part of the upper end of the box body, and an aviation fuel tank liquid level sensor is arranged at the rear part of the upper end of the box body The mounting hole and the aviation fuel tank return hole are provided, a metal sedimentation tank is installed at the lower end of the box body, the right end of the metal sedimentation tank is connected to the aviation fuel tank sewage mounting hole, the lower end of the box body is provided with an aviation fuel tank oil inlet hole, the lower right end of the box body is provided with an oil outlet mounting hole, the top plate of the box body is provided with an aviation fuel tank fire extinguishing agent pipeline mounting hole, the aviation fuel tank fire extinguishing agent pipeline mounting hole is connected to a metal fire extinguishing agent delivery metal pipeline, and a fire extinguishing agent spray head is fixedly installed on the end of the quick connection port of the metal fire extinguishing agent delivery metal pipeline away from the aviation fuel tank.

[0006] By adopting the above technical solution: the material is selected to be welded from 304-GB / T328 stainless steel, the tightness and strength have been tested, and the safety is high. By setting a fire extinguishing agent spray head on the top plate, when a fire occurs in the box, the fire extinguishing foam can be sprayed onto the oil surface to form a fire extinguishing isolation layer to prevent fuel combustion.

[0007] Preferably, the metal transverse partition and the metal longitudinal partition are both provided with an aviation fuel tank oil separator inlet hole and an aviation fuel tank oil separator oil guide hole.

[0008] By adopting the above technical solution: the metal transverse partition and the metal longitudinal partition play the role of blocking oil and preventing waves, thereby improving safety and avoiding leakage.

[0009] Preferably, both sides of the metal transverse partition and the metal longitudinal partition are coated with anti-corrosion paint, the outer surface of the metal steel frame assembly is coated with anti-corrosion paint, and the inner side of the outer wall of the metal box body is coated with anti-corrosion paint.

[0010] By adopting the above technical solution, all positions contacting the surface are treated with anti-corrosion and have high corrosion resistance.

[0011] The fuel supply monitoring system of the aviation fuel tank of the hot-blowing snowplow includes an aviation fuel tank monitoring host. The aviation fuel tank monitoring host receives in real time various parameters collected by sensors corresponding to oil level monitoring, oil quantity monitoring, water level monitoring, oil temperature monitoring, oil pressure monitoring, oil overflow monitoring and anti-static monitoring installed on the aviation fuel tank of the snowplow, and transmits them to the vehicle-mounted industrial control integrated machine through protocol communication. The vehicle-mounted industrial control integrated machine displays the parameters in audio and video and transmits them to the remote management service system through the 4G / 5G wireless network. The remote management service system transmits the operating status information in the form of text or image to the working mobile phone or the management center monitoring computer for display.

[0012] By adopting the above technical solution, the situation inside the aviation fuel tank can be digitally monitored in real time, which is convenient for management and improves safety.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By arranging the installation holes for the aviation fuel tank fire extinguishing agent pipeline to connect to the external fire truck to spray fire extinguishing foam agent on the oil surface inside the tank, a fire extinguishing isolation layer can be formed on the oil surface to prevent the fuel from burning or extinguish the burning aviation fuel, thus improving safety.

[0015] 2. By comprehensively digitally monitoring the aviation fuel tank, collecting data parameters through the aviation fuel tank monitoring host and in-vehicle industrial control integrated machine, and transmitting the operation status information to the working mobile phone or the monitoring computer of the management center for display in the form of text or images through the remote management service system, it is more conducive to monitoring the aviation fuel status inside the aviation fuel tank, facilitating management and data analysis, and reducing the accident rate.
