Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft maintenance technology, specifically to an aircraft de-icing and heating vehicle. Background Technology
[0002] Before takeoff, aircraft need to have all ice removed from their fuselage in rainy, snowy, or icy weather. Currently, de-icing trucks are mainly used to spray de-icing fluid for de-icing. The basic principle of aircraft de-icing fluid is to use a certain liquid to reduce the adhesion of ice to the aircraft surface or to reduce the freezing of water on the aircraft's anti-icing surface. Anti-icing fluids used include methanol, ethanol, and ethylene glycol.
[0003] However, during the de-icing process, some areas of the aircraft cannot be reached by de-icing spray, or some aircraft components cannot be sprayed with de-icing fluid. Currently, heating is mainly done using hot air guns, which results in uneven temperature, a small heating range, and low efficiency, seriously affecting the aircraft de-icing effect. Now, a high-efficiency, high-power heated de-icing vehicle has been invented to improve the aircraft de-icing effect. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an aircraft de-icing and heating vehicle for de-icing parts of an aircraft that are inaccessible to de-icing spray or where de-icing fluid cannot be sprayed.

The heater heats the airflow input to the high-pressure blower and then outputs the hot air through a telescopic duct, thereby increasing the surface temperature of the aircraft to achieve de-icing. It can heat and blow away ice and snow from multiple key components such as the aircraft flap control linkage, rectifier cone, temperature probe, and aircraft water system valves.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0022] like Figure 1 and Figure 2 As shown in the figure, a specific embodiment of this utility model provides an aircraft de-icing and heating vehicle. This equipment is mainly used for de-icing areas of an aircraft where de-icing fluid cannot be used. It has the advantages of good de-icing effect and high flexibility of use. It includes a vehicle body 100 and a heating control unit installed on the vehicle body 100. The heating control unit includes a high-pressure blower 200. The output end of the high-pressure blower 200 is connected to a telescopic air duct 300. The output end of the telescopic air duct 300 is detachably connected to an air knife assembly. The input end of the high-pressure blower 200 is provided with a heater 400. The heater 400 and the high-pressure blower 200 are signal-connected to a control module 500. The heater 400 and the high-pressure blower 200 are connected to an external cable and a generator module 600 through a circuit.
[0023] like Figure 1 and Figure 2 As shown, through the above settings, this embodiment adopts a movable vehicle body 100 structure, which can be moved to the use area during use. In order to facilitate the movement of the entire device, a front axle 700 with braked wheel set is provided at the bottom of the front end of the vehicle body 100, and a movable wheel set 800 is provided at the bottom of the rear end of the vehicle body 100. A towing frame 900 is connected to the front end of the front axle 700. Before use, the vehicle body 100 is moved by connecting the towing frame 900 to the towing vehicle. After moving to the work area, the front axle 700 with braked wheel set is braked to ensure that the vehicle body 100 remains stable.
[0024] This device can be powered via an external cable or by a generator module 600, which can be a diesel generator, depending on the site conditions. After pneumatic operation by the high-pressure blower 200 and heater 400, the heater 400 heats the airflow input to the high-pressure blower 200, and the hot air is output through the telescopic duct 300. This hot air raises the surface temperature of the aircraft, achieving de-icing. It can heat and defrost ice and snow on multiple critical components such as aircraft flap control links, rectifier cones, temperature probes, and aircraft water system valves. It can also heat and defrost cargo and passenger doors when they are icy, and meet various heating needs during post-flight maintenance. It offers high flexibility and ease of operation. The heating parameters, such as heating power and airflow, are controlled by the control module 500. The control module 500 uses a frequency converter module to control the airflow and air pressure at the outlet. The heating power can be adjusted to meet the needs of different working conditions and ensure that the outlet temperature is adjustable. The air knife assembly installed at the front end of the telescopic duct 300 is used to increase the airflow velocity at the outlet and improve the de-icing efficiency. The air knife assembly uses existing technology products, and the specifications are selected as needed, which will not be elaborated here. In order to facilitate the connection of the air knife, the front end of the telescopic duct 300 is provided with an air knife interface. The interface can adopt a quick-release structure, such as a snap-on quick-release structure, to improve the convenience of disassembly and assembly. A handle is also required on the air knife assembly so that technicians can hold it to carry out de-icing operations.
[0025] like Figure 1 and Figure 2 As shown, when using this device, the length of the telescopic duct 300 needs to be changed according to the de-icing location. To facilitate adjustment in different working environments, the telescopic duct 300 in this embodiment includes multiple duct body sections. The duct body sections are equipped with quick-release connectors at both ends. In this way, technicians can select the appropriate number of duct body sections for assembly according to the usage distance. The quick-release connectors improve assembly efficiency. The quick-release connectors can be the existing pipe connectors. Since the telescopic duct 300 is used to transport hot air, the high-pressure blower 200 is a certain distance away from the air outlet of the telescopic duct 300 during use. In order to reduce heat loss, this embodiment has a heat insulation layer on the surface of the duct body to play a heat insulation role, ensuring that the air outlet maintains a high temperature and improving de-icing efficiency.
[0026] As mentioned earlier, an external cable is provided on the vehicle body 100 for easy external power supply. For convenient storage, this embodiment features a rotatable cable reel 1000 on the vehicle body 100. The external cable is wound around the cable reel 1000 during storage, thus serving to store the cable. Furthermore, the telescopic duct 300 also needs to be stored on the vehicle body 100 when not in use. In this embodiment, a duct storage box 1100 is provided at one end of the vehicle body 100 where the telescopic duct 300 is located. The duct storage box 1100 has a storage opening at its front, with a baffle hinged to the opening. The duct storage box 1100 stores the telescopic duct 300, preventing the duct structure from falling off, thus integrating various structures into one unit for convenient management and use.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
