[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0030] In the description of this application, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "longitudinal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] like Figures 1 to 2As shown in the embodiment of this application, a drying device for sealant on the window glass of a high-speed train is introduced, comprising: a housing, which is independently set; the housing includes a mounting groove 1, which is fastened to the window glass of the high-speed train to form an annular drying chamber, and the sealant on the outer periphery of the window glass is located in the drying chamber; a heating element 2 is installed in the mounting groove 1, and the heat generated by the heating element 2 is dissipated into the drying chamber to dry the sealant on the window glass of the high-speed train; a suspension device 4 is installed on the outside of the housing, and the end of the suspension device 4 is detachably connected to the high-speed train.

[0033] With the above setup, the mounting groove 1, which is adapted to and engages with the window glass of the EMU, is used to connect the mounting groove 1 of the drying equipment with the window glass to form a drying chamber. This allows the sealant adhering to the outer periphery of the window glass to be placed inside the drying chamber, achieving the effect of drying the sealant in an independent drying chamber. At the same time, by installing a heating element 2 in the mounting groove 1 of the drying equipment, the gas inside the sealed drying chamber is heated to raise the temperature inside the drying chamber, thereby accelerating the drying process of the sealant in the EMU window glass.

[0034] In this embodiment, the heating element 2 is a heating tube 20. The heating tube 20 has a heat dissipation body such as an electric heating wire. It uses the current to dissipate heat to heat the airflow in the drying chamber. At the same time, the heating tube 20 extends in the same direction as the mounting groove 1 so that the heating tube 20 is arranged around the outer circumference of the train window glass. This allows the heating tube 20 to heat and dry the sealant in all parts of the window glass, improving the uniformity of drying of the sealant in all parts of the window glass.

[0035] Furthermore, a fixing seat 3 is provided in the mounting groove 1, and the heating tube 20 passes horizontally through the mounting hole on the fixing seat 3 to fix the heating tube 20 extending in the same direction as the mounting groove 1, so as to avoid problems such as the heating tube 20 being contacted and collided with the groove wall of the mounting groove 1 due to radial deviation or other displacement.

[0036] Optionally, the mounting base 3 is made of a high heat insulation material to avoid problems such as deformation of the mounting base 3 caused by the heating tube 20 heating up, thereby achieving the effect of effectively fixing and installing the heating tube 20. The mounting base 3 can be made of any of the existing high heat insulation materials, such as ceramics.

[0037] like Figures 1 to 2As shown in the embodiment of this application, the mounting groove 1 is a square ring structure to fit the outer periphery of the window glass of the EMU. Of course, in order to fit the window glass of the EMU train, the mounting groove 1 needs to be set as a square ring, and the inner peripheral sidewall 15 and the outer peripheral sidewall 16 of the square ring mounting groove 1 are respectively located on the inner peripheral side and the outer peripheral side of the outer periphery of the window glass, so as to ensure that the sealant coated on the outside of the window glass is always in the mounting groove 1, thereby achieving the effect of efficiently drying the sealant by using the heating element 2 in the mounting groove 1.

[0038] Furthermore, the inner peripheral sidewall 15 of the mounting groove 1 is generally set higher than the outer peripheral sidewall 16, so that the end of the inner peripheral sidewall 15 of the mounting groove 1 is in contact with the window glass of the EMU and the end of the outer peripheral sidewall 16 is in contact with the outer wall of the EMU. This achieves the effect that the inner and outer peripheral sidewalls 16 of the mounting groove 1 are sealed to the window glass and the outer wall of the EMU after being fastened, respectively, to form a drying chamber.

[0039] like Figures 1 to 2 As shown, each side of the square annular mounting groove 1 corresponds to the corresponding side of the EMU window glass, including the upper side 11, the lower side 12, the left side 13 and the right side 14, respectively corresponding to the upper, lower, left and right sides of the window glass; and the adjacent parts of the above-mentioned sides are connected by rounded corners to form the square annular mounting groove 1.

[0040] like Figures 1 to 2 As shown in the embodiment of this application, there are multiple heating tubes 20; each heating tube 20 is installed in a corresponding side of the square annular mounting groove 1 in a straight line; for example, the upper heating tube is installed in the upper side 11, the lower heating tube is installed in the lower side 12, the left heating tube is installed in the left side 13, and the right heating tube is installed in the right side 14. At the same time, the adjacent ends of the above-mentioned heating tubes 20 are connected by wires, so that each heating tube 20 together constitutes a heating element 2 and is connected to an external controller, an external power supply, etc. through wires, so as to achieve the effect of controlling each heating tube 20 separately by the same controller and the same external power supply.

[0041] like Figures 1 to 2 As shown in the embodiment of this application, multiple fixing seats 3 are arranged at intervals on each side of the square annular mounting groove 1. Each fixing seat 3 on the same side is provided with a coaxially extending mounting hole that passes through the corresponding fixing seat 3. The heating tube 20 in the corresponding side is horizontally and coaxially inserted into the mounting hole of each fixing seat 3 to achieve the fixed installation of each heating tube 20. Optionally, a fixing seat 3 is provided at each end of each side of the square annular mounting groove 1 to achieve the effect of fixing and assembling the two ends of each heating tube 20 through the fixing seat 3 respectively.

[0042] In this embodiment, the inner circumferential sidewall 15 and outer circumferential sidewall 16 of the square annular mounting groove 1 are respectively provided with protective adhesive strips 17 covering at least the ends. The mounting groove 1 uses the protective adhesive strips 17 to engage with the window glass of the EMU, thereby protecting the window glass and the outer wall of the EMU and effectively preventing scratches during the engagement of the drying equipment housing. Of course, the protective adhesive strips 17 covering at least the ends of the inner circumferential sidewall 15 and outer circumferential sidewall 16 of the mounting groove 1 can elastically deform when in contact with the window glass and the outer wall of the EMU. This elastic deformation ensures a tight seal at the engagement point between the mounting groove 1 and the window glass and the outer wall of the EMU, improving the sealing performance of the drying chamber formed by the engaged mounting groove 1 and the EMU, and further increasing the drying and curing rate of the sealant by the heating element 2. Optionally, the protective adhesive strips 17 are made of a material with elastic cushioning properties, such as rubber.

[0043] In this embodiment, the suspension device 4 of the drying equipment includes a chain 8 and a suction cup 9; the first end of the chain 8 is fixedly connected to the outer wall of the mounting groove 1, and the second end of the chain 8 is connected to the suction cup 9, which is detachably attached to the train set; the chain 8 can be any existing structural form of chain 8, such as a metal chain 8, a rope chain 8, etc. The chain 8 can be freely deformed to achieve the effect of tightening or loosening the chain 8 to suspend and pull the shell, and to freely disassemble it.

[0044] In this embodiment, multiple suspension devices 4 are connected to opposite sides of the mounting groove 1 of the drying equipment. The chains 8 of each suspension device 4 on both sides extend in opposite directions and the suction cups 9 are detachably attached to the train set or the train set window glass, so that the chains 8 pulled in opposite directions can suspend and fix the square ring mounting groove 1, effectively preventing the shell of the drying equipment from tilting or shaking.

[0045] like Figures 1 to 2 As shown in the embodiment of this application, the mounting groove 1 has an upper part 11 and a lower part 12 corresponding to the upper and lower sides of the train window glass, respectively. Multiple first suspension devices 41 and second suspension devices 42 are arranged at intervals on the upper part 11 and the lower part 12 of the mounting groove 1. The lower side wall of the upper part 11 is connected to the upper end of the first chain 411 of the first suspension device 41, and the first chain 411 extends downward, with the lower end being attracted to the train window glass via the first suction cup 412. The upper side wall of the lower part 12 is connected to the lower end of the second chain 421 of the second suspension device 42, and the second chain 421 extends upward, with the upper end being attracted to the train window glass via the second suction cup 422. Optionally, one first suspension device 41 and one second suspension device 42 are respectively provided near the left and right sides to achieve the effect of suspending and fixing the four corners of the square annular mounting groove 1.

[0046] like Figures 1 to 2 As shown in the embodiment of this application, a plurality of third suspension devices 43 are also arranged at intervals on the upper side 11 of the mounting groove 1; the lower end of the third chain 431 of the third suspension device 43 is connected to the upper side wall of the upper side 11 of the mounting groove 1, the third chain 431 extends upward and attaches the third suction cup 432 provided at the upper end to the outer side of the train body, so that the mounting groove 1 of the drying equipment is also fixed to the train body, further improving the stability and reliability of the suspended drying equipment.

[0047] In this embodiment of the application, the drying equipment further includes a temperature controller 5 and a temperature sensor 6; the temperature sensor 6 is installed in the mounting groove 1 and is used to detect the temperature inside the drying chamber; the temperature sensor 6 can be installed at any position in the square annular mounting groove 1; optionally, the temperature sensor 6 is set at the corner of the upper side of the square annular mounting groove 1 to detect the corner temperature inside the drying chamber as a basis for determining the temperature inside the chamber.

[0048] Meanwhile, in this embodiment, the temperature controller 5 of the drying equipment is located outside the housing. The heating element 2 and the temperature sensor 6 are respectively connected to the temperature controller 5 via connecting lines 7 passing through the mounting slot 1. Optionally, the heating element 2 and the temperature sensor 6 exit the mounting slot 1 via different connecting lines 7, and the two connecting lines 7 are merged into a single connecting line 7. The end of the connecting line 7 is connected to the temperature controller 5, so that the temperature controller 5 can receive temperature detection data transmitted by the temperature sensor 6 and control parameters such as the on / off state of the heating element 2. Furthermore, the power supply for the drying equipment can be a battery, an external power cord, etc. Optionally, the temperature controller 5 can be connected to an external 220V power supply to achieve controllable power supply for the drying equipment.
