Description

Technical Field

[0001] This utility model relates to the technical field of de-icing devices, specifically to a de-icing device. Background Technology

[0002] Currently, aircraft de-icing primarily involves spraying de-icing fluid onto the icy surface. This fluid is typically composed of ethylene glycol and propylene glycol, which, when mixed with water, lowers the freezing point to below -50°C. There are two spraying methods: one is using a dedicated aircraft de-icing truck. These trucks offer high mobility and efficiency, but are expensive, resulting in high costs per operation. They are suitable for situations where the aircraft is covered in large areas of ice and snow. The second method is manual spraying of the de-icing fluid. Manual de-icing offers greater flexibility, precision, and lower costs per operation, making it suitable for situations where de-icing trucks are unsuitable or for small, localized de-icing needs. However, the simple ladders used in manual de-icing lack self-propelled and lifting capabilities, and the temperature, pressure, and flow rate of the de-icing device are not adjustable, making the operation extremely inconvenient and inefficient.

Detailed Implementation

[0026] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] See Figures 1-7 As shown, a de-icing device includes a mobile vehicle 4, a first heating device 10, a second heating device 7, a centrifugal fan 8, a de-icing fluid tank 9, a lifting platform 6, and an obstacle avoidance component 12. The first heating device 10, the de-icing fluid tank 9, and the lifting platform 6 are all fixed to the mobile vehicle 4. The first heating device 10 is connected to the de-icing fluid tank 9. The second heating device 7 and the centrifugal fan 8 are fixed to the first heating device 10. The centrifugal fan 8 is connected to the second heating device 7. The obstacle avoidance component 12 is fixed to the outer periphery of the mobile vehicle 4.

[0028] Specifically, the mobile vehicle 4 is equipped with a vehicle-mounted platform, on which all components are installed. The first heating device 10 and the de-icing fluid tank 9 are fixed side-by-side in the middle of the vehicle-mounted platform. The lifting platform 6 is fixed at the front of the vehicle-mounted platform. The lifting platform 6 is a hydraulic lifting platform used for personnel lifting operations, such as... Figure 4 As shown, except for the lifting platform 6, all other components are covered by sheet metal covers 11 to prevent internal components from being damaged by rain or external forces. This utility model is used to replace traditional manual de-icing tools at airports and complements large aircraft de-icing vehicles. This equipment is multifunctional, mobile, highly efficient in de-icing, and not limited to aircraft de-icing.

[0029] Preferred, such as Figure 6 and Figure 7As shown, the first heating device 10 includes a first drive pump 101, a buffer water tank 102, a heating module, and a spraying device. The heating module is fixed inside the buffer water tank 102. The first drive pump 101 is connected between the buffer water tank 102 and the spraying device. The buffer water tank 102 is connected to the de-icing fluid tank 9. The de-icing fluid in the de-icing fluid tank 9 can flow into the buffer water tank 102, whereby the heating module heats the de-icing fluid, which is then pumped to the spraying device by the first drive pump 101 to achieve spraying of the de-icing fluid. The spraying device can be a water gun, connected between the first drive pump 101 and the water gun via a hose. The first drive pump 101 can be a high-pressure plunger pump.

[0030] Preferably, the buffer tank 102 is equipped with a level gauge and a temperature sensor, so that the content of de-icing fluid in the buffer tank 102 can be known through the level gauge, and the heating temperature of the de-icing fluid in the buffer tank 102 can be known through the temperature sensor. A display screen is provided on the outside of the first heating device 10, and the heating module, level gauge and temperature sensor are all connected to the display screen to display the corresponding data.

[0031] Preferably, a flow meter and a pressure sensor are provided at the outlet of the first drive pump 101. The flow meter and pressure sensor are also connected to a display screen, and the flow rate and pressure of the de-icing fluid can be adjusted by the first drive pump 101 based on the values ​​measured by the flow meter and pressure sensor.

[0032] Preferred, such as Figure 5 As shown, the de-icing fluid tank 9 is equipped with a second drive pump 93, which is connected to the buffer water tank 102. The de-icing fluid tank 9 also includes a tank body 91 and a level pipe 92, which connects the top and bottom surfaces of the tank body 91 to facilitate visual observation of the fluid level within the tank body 91. The second drive pump 93 can pump the de-icing fluid from the de-icing fluid tank 9 to the buffer water tank 102 for heating. The second drive pump 93 can be a water pump.

[0033] Preferably, the system also includes a generator set 5, which is connected to the mobile vehicle 4, the first heating device 10, the second heating device 7, the centrifugal fan 8, the de-icing fluid tank 9, the lifting platform 6, and the obstacle avoidance device 12. The generator set 5 provides power to all components of the mobile vehicle 4, avoiding the limitations imposed by the need for electrical wiring and improving the flexibility of the mobile vehicle 4. The generator set 5 can be a diesel generator set, capable of outputting AC220V and AC380V voltages, and can be used as a power source for mobile applications.

[0034] Preferably, the mobile vehicle 4 is equipped with a ladder 2, which is connected to the lifting platform 6, so as to facilitate construction workers to climb from the ladder 2 to the lifting platform 6.

[0035] Preferably, the mobile vehicle 4 is equipped with a hook 1 for traction, so that the mobile vehicle 4 can move back and forth autonomously, turn around in place, or be tractioned by the hook 1.

[0036] Preferred, such as Figure 4 As shown, the number of obstacle avoidance components 12 is at least four, and these at least four obstacle avoidance components 12 are fixed at at least four corner positions of the mobile vehicle 4. More than four obstacle avoidance components 12 can also be installed, allowing them to be placed in positions other than the four corners. This prevents the equipment from colliding with the aircraft during operation. When the equipment is about to collide with the aircraft, an audible and visual alarm is triggered via the electrical system 3, and the equipment stops operating, thus improving operational safety. The obstacle avoidance components 12 can be sensor-type, but are not limited to ultrasonic, laser, or similar types.

[0037] Preferably, the device also includes an electrical system 3, which is connected to the mobile vehicle 4, the first heating device 10, the second heating device 7, the centrifugal fan 8, the de-icing fluid tank 9, the lifting platform 6, and the obstacle avoidance device 12. The electrical system 3 enables control of all components and is integrated inside the on-board platform of the mobile vehicle 4. The operator can operate the equipment via external buttons or without a remote control.

[0038] In operation, the de-icing fluid tank 9 is filled with de-icing fluid. The second drive pump 93, according to the instructions of the electrical system 3, injects de-icing fluid into the buffer tank 102. The electric heating module inside the buffer tank 102 then starts working. The electrical system 3 can automatically control the temperature of the de-icing fluid via a temperature sensor inside the tank. After heating to the set temperature, the de-icing fluid is sprayed onto the ice surface through the first drive pump 101 and a spraying device to melt the ice. When the liquid level in the buffer tank 102 drops to a certain height, the second drive pump 93 restarts to replenish the tank with de-icing fluid, and this cycle repeats. The electrical system 3 can provide feedback and adjustment of the pressure and flow rate of the de-icing fluid through the pressure sensor and flow meter at the outlet of the first drive pump 101.

[0039] Because de-icing fluid is expensive, hot air de-icing can be used when the ice layer is thin or when parts such as door locks and bolts need to be thawed. Powering the generator set 5 starts the second heating device 7 and centrifugal fan 8. The outlet of the second heating device 7 is equipped with a temperature sensor and a wind speed sensor. The electrical system 3 can automatically control the temperature of the second heating device 7 via the temperature sensor. The air delivered by the centrifugal fan 8 is heated by the second heating device 7 and then blown onto the ice surface through an external hot air duct, thereby thawing the ice. The electrical system 3 can adjust the airflow and air pressure of the centrifugal fan 8 via the wind speed sensor.

[0040] When the aircraft or object requiring de-icing is large, or the de-icing location and height vary significantly, workers enter the lifting platform 6 via ladder 2, and then use a remote control equipped with electrical system 3 to operate the mobile vehicle 4 to move it to the vicinity of the de-icing location. They then use a hot air hose or high-pressure water gun to perform de-icing. The lifting platform 6 can be raised and lowered to meet different de-icing height requirements.

[0041] This utility model of de-icing equipment utilizes a combination of heated de-icing fluid and hot air for de-icing. The mobile cart further increases the de-icing area and efficiency, solving the problem of low efficiency in small-area, localized de-icing operations on aircraft in existing technologies. The first heating device controls the flow rate of the de-icing fluid and the pressure of the spraying tools, adapting to various de-icing conditions. A generator set powers the entire mobile cart, enabling electrical control of all components. A lifting platform allows for de-icing at different heights.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
