[0020] Please refer to the following: Figures 1-3 The special coating curing constant temperature device provided in the embodiments of this application will now be described.
[0021] A special coating curing constant temperature device includes a control system, a heating system 3 and an execution system 4. The execution system 4 is used to fix on the surface 5 of special equipment to enclose the special coating to be cured inside it. The heating system 3 is connected to the execution system 4 and is used to generate hot air and deliver it into the execution system 4. The control system is electrically connected to the heating system 3.
[0022] This application uses an execution system 4 fixed to the surface of special equipment to enclose the special coating to be cured inside it. Hot air is generated by a heating system 3 and delivered to the execution system 4. The internal temperature of the execution system 4 is kept constant by a control system, which can provide a stable temperature environment for the curing process of the special coating and effectively meet the needs of the special coating in the curing process.
[0023] In some embodiments of this application, see Figure 2The heating system 3 includes a housing and an air heater 32, an axial fan 31 and a temperature sensor (not shown in the figure) disposed inside the housing. An air inlet 33 and an air outlet 34 are provided at both ends of the housing. The air heater 32 is used to generate hot air, and the axial fan 31 is used to deliver the hot air to the inside of the execution system 4. The control system is electrically connected to the air heater 32 and the temperature sensor respectively.
[0024] For details, please refer to Figure 2 The control system includes a fan controller 35, a switching power supply 36, and a leakage current protector 37, all housed within the casing of the heating system 3. The axial fan 31, fan controller 35, switching power supply 36, and leakage current protector 37 are connected sequentially. The fan controller 35 controls the on / off operation of the axial fan 31, the switching power supply 36 supplies power to the fan controller 35, and the leakage current protector 37 provides leakage protection.
[0025] The existing heating system 3 can only heat according to its own set temperature, which is easily affected by environmental factors (it cannot provide feedback when the ambient temperature rises or falls, resulting in continuous output of rated power). However, the heating system 3 of this application has closed-loop control capability, which can adjust the power of the air heater 32 and the axial fan 31 in real time according to the difference between the ambient temperature and the set temperature, thus forming a stable constant temperature environment. The air heater 32 and the axial fan 31 are installed together. During normal operation, the air heater 32 and the axial fan 31 are turned on simultaneously, blowing hot air into the constant temperature cover 41. The temperature sensor is located at the air outlet 34 of the axial fan 31, which detects the temperature of the blown hot air in real time. When the detected temperature is higher than the set temperature, the temperature sensor transmits a signal to the control system. The control system temporarily turns off the air heater 32 and the axial fan 31 through the fan controller 35. When the detected temperature is lower than the set temperature, the control system turns on the air heater 32 and the axial fan 31 again.
[0026] In some embodiments of this application, see Figure 3 The execution system 4 includes a thermostatic cover 41, a heating pipe 42, and a fixing member 43. The thermostatic cover 41 is used to cover the outside of the special coating to be cured. One end of the heating pipe 42 is connected to the thermostatic cover 41, and the other end is connected to the air heater 32. The fixing member 43 is connected to the thermostatic cover 41 and is used to fix the thermostatic cover 41 to the surface of the special equipment.
[0027] The edges of the thermostatic cover 41 are lined with insulating cotton. A slight press allows the thermostatic cover 41 to fit snugly and conform to the surface 5 of the special equipment, forming a sealed space. When repairs are needed on the sides and bottom surface of the special equipment, the thermostatic cover 41 can be fixed to the surface using fasteners 43. The heating system 3 is connected to the thermostatic cover 41 in the execution system 4 via a heating pipe 42, ensuring a constant temperature environment inside the thermostatic cover 41. Simultaneously, the thermostatic cover 41 shell protects the cured area from contamination and damage, eliminating the risk of overturning due to pressure differences between the inside and outside of the thermostatic cover 41.
[0028] In some embodiments of this application, the fixing member 43 is a suction cup, and there are multiple of them, which are evenly arranged around the constant temperature cover 41.
[0029] Existing conventional heating devices can only adhere to the upper surface of special equipment aircraft by gravity, and are largely ineffective for the lower surface areas. This application uses suction cups to fix the thermostatic cover 41 to the side or bottom of the special equipment, eliminating the need for a separate insulation chamber. It can be used immediately after repair, is highly efficient and convenient, lightweight, and reusable, significantly reducing costs and improving maintenance efficiency. Furthermore, because the thermostatic cover 41 is soft, the suction cups allow the contact area of the thermostatic cover 41 to deform to adapt to the shape of the coating repair area, ensuring no gaps between the thermostatic cover 41 and the surface of the special equipment.
[0030] In this embodiment, the suction cup vacuum can reach -90KPa, and the suction force of a single suction cup is about 25.4kg, which allows the suction cup to adhere the entire thermostatic cover 41 to the surface of the special equipment for a long time. The suction cup is made of silicone material, which can remain soft in low-temperature environments.
[0031] In some embodiments of this application, a heat insulation block 44 is provided between the fixing member 43 and the thermostatic cover 41. The heat insulation block 44 is used to connect the suction cup and the thermostatic cover 41 to avoid thermal bridging and reduce heat loss, thereby further ensuring that the internal temperature of the thermostatic cover 41 remains constant.
[0032] In some embodiments of this application, see Figure 3 The constant temperature cover 41 includes a foldable frame and a thermal insulation layer, wherein the thermal insulation layer is connected to the frame.
[0033] The frame supports the thermal insulation layer, which is integrally molded without seams. The frame has a foldable structure, allowing it to be closed (similar to an umbrella), reducing its space footprint and facilitating storage and transportation. In other embodiments of this application, the frame may employ other foldable structures, which are not limited here.
[0034] In some embodiments of this application, the thermal insulation layer is made of 20mm thick rubber-plastic thermal insulation cotton. Rubber-plastic thermal insulation cotton has heat insulation, heat preservation, flame retardant, and waterproof properties, enabling the constant temperature cover 41 to adapt to various environmental conditions. In other embodiments of this application, the thermal insulation layer may also be made of other materials.
[0035] In some embodiments of this application, the outer side of the heating pipe 42 is provided with heat insulation cotton, and the connection between the heating pipe 42 and the thermostatic cover 41 and the connection between the heating pipe 42 and the air heater 32 are provided with sealing material.
[0036] In some embodiments of this application, the heating pipe 42 is a high-temperature silicone duct, which has flame-retardant, self-extinguishing, and high-temperature resistant properties. The heating pipe 42 is a single, continuous pipe without any joints, and is wrapped with a layer of thermal insulation cotton to reduce heat loss from the pipe exposed to the environment. In some embodiments of this application, the heating pipe 42 is connected to the thermostatic cover 41 and the air heater 32 via quick-connect interfaces, and the interfaces are sealed with polyurethane foam to prevent heating leaks.
[0037] In some embodiments of this application, see Figures 1-3 The control system includes a high-voltage control box 1 and a low-voltage control box 2. The high-voltage control box 1 is electrically connected to the low-voltage control box 2, and the low-voltage control box 2 is connected to the heating system 3. The low-voltage control box 2 is equipped with a temperature digital display instrument and a control panel.
[0038] Specifically, the high-voltage control box 1 and the low-voltage control box 2 are connected by cables. The input voltage of the high-voltage control box 1 is AC380V, and the low-voltage control box 2 is connected to the heating system 3 by cables (the cable length is 1-2 meters, which can reduce interference between the control system and the heating system 3).
[0039] In some embodiments of this application, the low-voltage control box 2 is equipped with a start button, a signal input port, a power input port, a temperature digital display instrument, and a control panel. The signal input port is used to connect to a temperature sensor, and the temperature data is displayed on the temperature digital display instrument. The power input port is used to connect to the high-voltage control box 1, and the control panel is used to set the temperature. After power is supplied, pressing the start button controls the air heater 32 and the axial fan 31 to work. The temperature digital display instrument and control panel on the low-voltage control box 2 can set the heating temperature. When the set temperature value reaches the preset value, the temperature sensor in the heating system 3 sends a signal to control the air heater 32 in the heating system 3 to stop. When the set temperature value is lower than the preset value, the air heater 32 in the heating system 3 will restart, achieving constant temperature closed-loop control.
[0040] In some embodiments of this application, the special equipment may be an aircraft; in other embodiments, the special equipment may be other equipment, and this application does not limit it.
[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
