DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In one embodiment, a mobile warming system is provided, such as Figure 1-7As shown, the mobile heating system includes a mobile frame 1, on which a radiator 13, a heating water tank 2 and a hot water circulation device are arranged. By setting up the mobile frame 1, it is convenient to move the position under the wing to heat different areas when the aircraft is stripped of paint. The heating water tank 2 is used to heat the internal medium. The internal medium of the heating water tank 2 can be water. The hot water circulation device is used to make the heated medium circulate between the radiator 13 and the heating water tank 2, and the heat dissipated by the radiator 13 is used to heat the underside of the wing. In this embodiment, the hot water circulation device includes a circulating water pump 3, an outlet pipe 5, and a return pipe 6. In addition to the pump body at the bottom, the circulating water pump 3 also includes an electric motor 8 connected to the top. The pump body is driven by the electric motor. The water outlet of the heated water tank 2 is connected to the water inlet of the radiator 13 through the outlet pipe 5. The water outlet of the radiator 13 is connected to the water inlet of the heated water tank 2 through the return pipe 6, so that the radiator 13 and the heated water tank 2 are circulated and connected through the outlet pipe 5 and the return pipe 6. The circulating water pump 3 is arranged on the pipeline of the outlet pipe 5.

[0028] The mobile heating system is used as follows: add an appropriate amount of water as a medium into the heating water tank 2, push the entire device to the underside of the aircraft wing through the mobile frame 1, and heat the internal medium through the heating water tank 2. The heating water tank 2 is an electrically heated water tank. Start the circulating water pump 3 to transport the heated medium in the heating water tank 2 to the radiator 13. The hot water in the heating water tank 2 is pumped by the circulating water pump 3 and supplied to the radiator 11 through the water outlet pipe 5 for heating. The hot water then flows back into the heating water tank 2 through the return pipe 6, thereby realizing the circulation of hot water. In this way, the heat dissipated by the radiator 13 heats the underside of the wing for paint stripping.

[0029] The mobile heating system can be specially used for heating the lower area of ​​the wing when the aircraft is stripping paint, thereby increasing the temperature of the lower side of the wing, which is beneficial to the paint stripping effect of the paint stripper after spraying the paint stripper, thereby improving the paint stripping efficiency. The mobile heating system is a mobile device, and handles 14 are provided on both sides of the top of the frame. The movement is achieved by staff pulling the handles 14, and it is convenient to move to various places on the lower side of the wing. The mobile heating system circulates hot water and other media inside the radiator, so the heating process is gentler and more controllable, and it is safer than heating methods such as light.

[0030] Further, in another embodiment, in combination Figure 1-7As shown, the heated water tank 2 of the mobile heating system includes a stainless steel water tank, and an electric heater 7 is provided inside the stainless steel water tank, and the water and other media in the stainless steel water tank are heated by the electric heater 7. The stainless steel water tank has a long service life, and the heating is more convenient by electric heating. In other embodiments, gas heating can also be used. An inspection cover is provided on the top of the stainless steel water tank of the heated water tank 2, which is used to clean the inside of the water tank and inspect the electric heater 7. The water outlet and the return port of the stainless steel water tank are respectively provided with a second joint 16 and a first joint 15. Loosening the two joints makes it convenient to directly pull out the heated water tank 2 for inspection, which is convenient and quick.

[0031] Further, in another embodiment, in combination Figure 1-7 As shown, the radiator 13 of the mobile heating system includes water collecting tanks 131 on both sides, and a plurality of heat dissipation pipes connected between the water collecting tanks 131 on both sides. These heat dissipation pipes are divided into three rows from top to bottom, and heat dissipation fins are provided on the heat dissipation pipes to improve the heat dissipation efficiency. The water inlet and the water outlet of the radiator 13 are respectively arranged on the water collecting tanks 131 on the left and right sides. An exhaust valve 10 is provided on the top of the water collecting tank 131 on the left side for discharging the internal gas. The exhaust of the exhaust valve 10 allows the pipes of the stainless steel finned radiator 13 to be filled with hot water, thereby improving the heat dissipation efficiency. When drainage is required, the exhaust valve 10 can also be opened to enable the hot water in the stainless steel finned radiator to flow back into the stainless steel heating water tank 2 as soon as possible.

[0032] Further, in another embodiment, in combination Figure 1-7 As shown, the radiator 13 of the mobile heating system is made of stainless steel, with high heat dissipation efficiency and long service life. It is arranged on the top of the frame 1. After hot water is injected into the radiator 13, the space above is heated, which is convenient for heating work near the lower side of the wing. The return water port on the water collecting tank on one side of the radiator 13 is located at the lowest position, that is, the return water port on the water collecting tank connected to the return water pipe 6 is located at a low position, so that the water inlet end of the stainless steel finned radiator 13 is higher than the return water end. In this way, especially in the winter environment, the radiator 13 can be automatically drained when the equipment is not in use, preventing the water pipes in the stainless steel finned radiator 13 from being damaged by low temperature, which plays a protective role.

[0033] Further, in another embodiment, in combination Figure 1-7 As shown, the frame 1 of the mobile heating system includes a frame structure, which includes four supporting legs and an upper and lower bracket. The radiator 13 and the heated water tank 2 are respectively arranged on the upper and lower brackets. Universal wheels 4 with brakes are respectively provided at the bottom of the four supporting legs of the frame structure to facilitate moving the position. When the position needs to be moved, the brake on the universal wheel 4 is released and the handle 14 is pulled to realize the movement of the heating system.

[0034] Further, in another embodiment, in combination Figure 1-7 As shown, the outlet pipe 5 and the return pipe 6 of the mobile heating system are stainless steel pipes with a long service life. A filter 12 and a ball valve are also provided on the outlet pipe 5. Two ball valves are provided on the outlet pipe 5, which are respectively located on the front and rear sides of the circulating water pump 3 to adjust the outlet water pressure of the circulating water pump 3. A ball valve is also provided on the return pipe 6. A drain valve 9 is provided at the bottom of the heating water tank 2. Impurities are filtered through the filter 12. The two sides of the circulating water pump 3 are connected to the pipeline through flanges to facilitate the maintenance of the circulating water pump 3.

[0035] Further, in another embodiment, in combination Figure 1-7 As shown, the mobile heating system also includes an intelligent control cabinet 11, which is arranged on the lower side of the rack 1. The intelligent control cabinet includes a cabinet body with stainless steel on the outside, and a main controller is arranged in the cabinet body. The main controller can be a PLC controller, and the main controller is electrically connected to a touch screen for realizing human-computer interaction. The touch screen can be operated by opening the cabinet door of the cabinet body; a temperature controller, a first contactor and a thermal protector for controlling the electric heater 7 in the heating water tank 2 are also arranged in the cabinet body. The temperature controller is equipped with a temperature sensor arranged in the heating water tank 2. The temperature controller is electrically connected to the main controller, and the main controller controls the start of the temperature controller. The temperature controller is used to control the temperature, and the first contactor is electrically connected to the temperature controller. The electric heater 7 is connected in series with the first contactor and the thermal protector, and the temperature controller controls the first contactor to be turned on and off. The control cabinet 11 is also provided with a second contactor for controlling the motor 8 of the circulating water pump 3. The second contactor is electrically connected to the main controller, and the operation of the circulating water pump 3 is controlled by the main controller.

[0036] Further, in another embodiment, in combination Figure 1-7 As shown, the cabinet of the mobile heating system is also provided with a buzzer for providing an alarm and a timer for controlling the working time. The buzzer and the timer are electrically connected to the main controller. In addition, the cabinet is also provided with an air switch, a key switch for controlling the connection and disconnection of the power supply, and a red emergency stop switch for power-off protection of the control circuit in an emergency state. The key switch can be operated after the cabinet door is opened, and the red emergency stop switch is located on the cabinet door for easy operation. The cabinet supplies power to various internal electrical components through a power supply line electrically connected to the air switch. The power supply line is also electrically connected to the key switch and the emergency stop switch for turning on the power supply and emergency shutdown. The connecting cable of the control cabinet 11 adopts a cable plus plug connection method.

[0037] By setting a timer, the mobile heating system can perform constant temperature timing control on the hot water in the heating water tank 2 through the control cabinet 11. When it is necessary to heat the medium in the heating water tank 2 to the set temperature and maintain this state for a certain period of time, the temperature controller reads the signal of the temperature sensor and determines whether it is necessary to open and close the first contactor according to the temperature. The timer is used for constant temperature timing. The main controller uses the timer to perform timing, and sends a signal to the main controller after the time is reached. The main controller controls the temperature controller to stop the constant temperature working state. During this process, after the medium in the heating water tank 2 exceeds the temperature, the temperature controller transmits a signal to the main controller, and the main controller controls the buzzer to alarm.

[0038] Furthermore, a communication line electrically connected to the main controller is provided in the cabinet of the mobile heating system to realize the functions of remote network diagnosis, remote troubleshooting and remote program modification. In other embodiments, a wireless communication module connected to the main controller can also be provided to realize this function.

[0039] In a specific application of an embodiment of the mobile heating system, the functions and usage of the mobile intelligent heating system are as follows:

[0040] When the lower side of the aircraft wing needs to be heated in winter, the main controller controls the temperature controller to turn on the electric heater 7 to heat the water in the heating water tank 2. When the water temperature reaches the set temperature, the main controller in the control cabinet 11 automatically starts the motor 8 to drive the circulating water pump 3 to operate, so that the hot water in the heating water tank 2 flows to the stainless steel finned radiator 13 through the outlet pipe 5. After the hot water passes through the internal pipe of the stainless steel finned radiator 13, the radiator 13 automatically heats up and dissipates heat, and then flows back to the stainless steel heating water tank 2 through the return pipe 6 to realize the circulation of hot water. The stainless steel control cabinet 11 is equipped with a PLC controller, which can control the connection and disconnection of the electric heater 7, as well as the start and stop of the motor 8. It also has system detection functions such as remote diagnosis and remote troubleshooting. At the same time, considering the use of maintenance-free components and the application of component intelligent inspection technology, the main controller reserves equipment information data interface and network interface, realizing remote operation and monitoring, and making interface reservations for subsequent equipment systematic management integration. Human-machine communication is achieved through the touch screen, and the various control actions required for the operation of the mobile heating system (including the connection and disconnection of the electric heater 7, the start and stop of the motor 8, and the control logic of the over-temperature alarm) are realized by the prepared PLC control program.

[0041] The advantages of this mobile heating system are as follows: Various existing heating heaters on the market cannot achieve controllable low-temperature heating of the radiator surface. The utility model heats the lower side of the aircraft wing with hot water or other flowing media, which avoids the possibility of fire caused by paint falling off due to excessively high surface temperature of the radiator, enhances the safety of the site, and achieves the purpose of local heating. At the same time, the mobile heating system has constant temperature, timing and alarm functions, which is safer. Human-computer interaction is realized through the touch screen, and it also has functions such as remote diagnosis, remote troubleshooting and remote program modification, which effectively saves time for after-sales service and solves the pain points that users cannot perform local heating on the lower side of the aircraft wing and the fire safety is not high.

[0042] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
