Detailed implementation manners

[0026] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the following further describes the exemplary embodiments of the present application in detail with reference to the attached Figures 1-3 Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] In the process of implementing the present application, the inventors found that maglev trains usually need to load a large number of electrical devices to maintain the long-term stable operation of the vehicle body system. The reasonable arrangement and installation of the devices are the key to the design of the equipment cabin. For maglev trains, the design of the equipment cabin needs to meet the following requirements: facilitating the loading, unloading and maintenance of the devices, saving maintenance time and cost; having a magnetic shielding function to avoid electromagnetic interference on the devices caused by the strong magnetic field of the on-vehicle superconducting magnet; having a thermal management system to facilitate the heat dissipation of the devices.

[0028] The existing vehicle body equipment cabins mainly focus on the research of materials and structural forms. For example, the skirt plates and bottom plates of the equipment cabins are made of composite materials, and there is less research on the functionality of the equipment cabins. Moreover, they do not have a magnetic shielding function and are difficult to protect the devices from strong magnetic field interference; the thermal management system is imperfect. There is research on the thermal management system of the electronic equipment cabin in the aviation field, usually setting a sufficient ventilation environment for air cooling of the devices. However, traditional air cooling is not applicable to the pipe maglev train in a low-vacuum environment.

[0029] In view of the above problems, the embodiments of the present application provide a multi-functional integrated equipment cabin for a maglev train, as Figures 1-3 shown, which includes an outer shell 10. The outer shell 10 is a housing with an open top and a hollow interior. A liquid cooling plate 20 is covered on the top of the outer shell 10, which together with the outer shell 10 constitutes the external structure of the equipment cabin. A refrigerant flows through the liquid cooling plate 20. A loading device 30 is installed in the inner cavity of the outer shell 10. The top of the loading device 30 is closely attached to the bottom of the liquid cooling plate 20. A shielding layer 101 is provided on the inner wall of the outer shell 10.

[0030] During specific implementation, after placing the loading device 30 inside the outer shell 10, then covering the liquid cooling plate 20 on the top of the outer shell 10, and using bolts to lock the liquid cooling plate 20, the outer shell 10, and the loading device 30 together to obtain an integrated equipment cabin. After connecting the electrical connector interfaces inside the equipment cabin, the entire equipment cabin (as Figure 2 shown) is installed at the bottom of the vehicle body. The shielding layer 101 is located between the outer shell 10 and the loading device 30 and is used to shield the strong magnetic field generated by the vehicle-mounted magnet. The bottom of the liquid cooling plate 20 is closely attached to the top of the loading device 30, and the refrigerant is used to take away the heat from the surface of the loading device 30 and the outer shell 10.

[0031] The multi-functional integrated equipment cabin of the maglev train provided in this embodiment has functions such as magnetic shielding and active thermal control while being conveniently installed. It can shield the strong magnetic field of the vehicle-mounted magnet, and actively control the temperature by detecting the equipment temperature in real time to maintain a constant temperature and low magnetic environment in the equipment cabin. Different from the equipment cabins in traditional maglev trains that use air cooling for temperature reduction, the equipment cabin in this embodiment uses refrigerant for heat exchange and can be used on the pipe maglev train in a low-vacuum environment.

[0032] As a preferred solution, as Figure 1 、 Figure 3 shown, a plurality of equipment electrical interfaces 301 are provided on the side surface of the loading device 30, and a plurality of electrical connector plugs 102 are provided on the side wall of the outer shell 10. The plurality of electrical connector plugs 102 respectively correspond to the plurality of equipment electrical interfaces 301, and the inner sides of the plurality of electrical connector plugs 102 are connected to each other.

[0033] During specific implementation, before the above-mentioned integrated equipment cabin is assembled, the inner sides of the plurality of electrical connector plugs 102 are corresponding and connected one by one. After the connection is completed, the redundant electrical connector plugs 102 can be used for the electrical connection of other electrical equipment in the equipment cabin.

[0034] As a preferred solution, as Figure 1 、 Figure 3 shown, a circle of equipment outer edge 302 is provided around the top of the loading device 30, and a circle of housing outer edge 103 is provided around the top of the outer shell 10. After the loading device 30 is placed inside the outer shell 10, an installation space 104 is reserved between the five adjacent surfaces of the loading device 30 and the inner wall of the outer shell 10, and the loading device 30 is overlapped on the housing outer edge 103 through the equipment outer edge 302.

[0035] During specific implementation, during the assembly process of the integrated equipment cabin, on the one hand, the outer edge 103 of the housing serves to support the outer edge 302 of the equipment, enabling the loaded equipment 30 to be lapped within the outer housing 10. At the same time, a part of the installation space 104 is reserved between the loaded equipment 30 and the outer housing 10, facilitating the smooth entry of the loaded equipment 30 into the outer housing 10. Meanwhile, the loaded equipment 30 can move slightly within the range of the installation space 104, enabling the alignment between the electrical connector plug 102 and the equipment electrical interface 301, so that the electrical connector plug 102 and the equipment electrical interface 301 can be successfully connected correspondingly. On the other hand, a circle of bolt holes can be opened on the outer edge 103 of the housing and the outer edge 302 of the equipment for bolt fastening connection between the liquid cooling plate 20, the loaded equipment 30, and the outer housing 10. Additionally, the height of the outer edge 103 of the housing from the electrical connector plug 102 and the height of the outer edge 302 of the equipment from the electrical interface 301 are kept consistent. The settings of the outer edge 103 of the housing and the outer edge 302 of the equipment can assist in positioning the loaded equipment 30 in the vertical direction by the outer housing 10, improving the installation accuracy and convenience.

[0036] As a preferred solution, as Figure 1 shown, the present application further includes a fixed track chute 40. The fixed track chute 40 is an L-shaped straight plate. The fixed track chute 40 includes a bottom plate 401 and a side plate 402 that are perpendicularly connected to each other. The bottom plate 401 is used to support the outer housing 10, and the side plate 402 is connected to the main body structure 50 inside the maglev train. Baffles 403 are respectively arranged on both sides of the bottom plate 401. The baffles 403 are concave-shaped. The bottom plate 401 and the two baffles 403 together form a chute for the outer housing 10 to slide. The outer side walls of both sides of the outer housing 10 are respectively clamped with the two baffles 403, and the bottom of the outer housing 10 is slidably connected to the bottom plate 401.

[0037] As a preferred solution, as Figure 1 shown, a plurality of openings 404 are opened on the side plate 402. The plurality of openings 404 respectively correspond to a plurality of equipment electrical interfaces 301. A plurality of vehicle electrical interfaces 501 are provided on the main body structure 50 of the vehicle. The plurality of vehicle electrical interfaces 501 respectively correspond to the plurality of equipment electrical interfaces 301. The outer sides of the plurality of electrical connector plugs 102 are connected to the plurality of vehicle electrical interfaces 501 after passing through the plurality of openings 404.

[0038] During specific implementation, after the integrated equipment cabin is assembled, it needs to be installed on the main body structure 50 of the vehicle body. The fixed track chute 40 is pre-installed on the main body structure 50 of the vehicle body. The side plate 402 is connected to the main body structure 50 inside the maglev train, so that the bottom plate 401 is in a horizontal position. The integrated equipment cabin enters the chute from the open side, and the baffle plates 403 on both sides are respectively clamped with the outer walls on both sides of the outer shell 10. The integrated equipment cabin is slowly pushed inward along the chute, and the outer sides of the multiple electrical connector plugs 102 are respectively connected to the multiple vehicle body electrical interfaces 501 in one-to-one correspondence through the multiple openings 404. The height of the bottom plate 401 from the opening 404 is the same as the height of the bottom of the outer shell 10 from the electrical interface 301. The cooperation of the two baffle plates 403 completes the accurate positioning between the integrated equipment cabin and the fixed track chute 40. The design of the chute structure enables the integrated equipment cabin to be quickly and conveniently installed on the main body structure 50 of the vehicle body, and during use, the integrated equipment cabin can be smoothly slid out and removed along the chute, facilitating later maintenance and other operations.

[0039] As a preferred solution, as Figures 1-3 shown, the liquid cooling plate 20 is a blow-molded double-layer aluminum alloy structure. The liquid cooling plate 20 includes a lower bottom plate 201 and an upper blow molding flow channel 202. The blow molding flow channel 202 is evenly arranged in a snake shape on the bottom plate 201, increasing the contact area between the refrigerant and the loading equipment 30 and improving the heat exchange efficiency. The bottom plate 201 is closely arranged with the top of the loading equipment 30. A refrigerant device 60 is arranged inside the maglev train. The output end of the refrigerant device 60 is connected to the inlet of the blow molding flow channel 202 through an inlet liquid hose 70, and the input end of the refrigerant device 60 is connected to the inlet of the blow molding flow channel 202 through an outlet liquid hose 80.

[0040] As a preferred solution, as Figure 1 、 Figure 3 shown, a temperature sensor 303 is arranged on the loading equipment 30 at the internal cavity of the outer shell 10. The temperature sensor 303 is used to detect the real-time temperature of the loading equipment 30.

[0041] As a preferred solution, as Figure 3 shown, a temperature control system 90 is arranged inside the maglev train. The signal output end of the temperature sensor 303 is electrically connected to the temperature control system 90, and the temperature control system 90 can control the refrigeration power of the refrigerant device 60.

[0042] During specific implementation, before assembling the integrated equipment cabin, the temperature sensor 303 is pre-installed on the loading device 30. After completing the assembly of the integrated equipment cabin, the refrigerant inlet and outlet of the liquid cooling plate 20 are respectively connected to the refrigerant equipment 60 through the liquid inlet hose 70 and the liquid outlet hose 80. The liquid inlet hose 70 and the liquid outlet hose 80 should have a certain length margin according to the movement range during the installation of the equipment cabin. During use, the temperature sensor 303 transmits the measured real-time temperature on the surface of the loading device 30 to the temperature control system 90, and the temperature control system 90 determines the temperature. If the temperature is too high, the refrigeration efficiency of the refrigerant equipment 60 is increased, and the flow rate in the blow-up flow channel 202 is adjusted by adjusting the refrigerant pressure to perform heat exchange cooling on the loading device 30 until the surface temperature of the loading device 30 is reduced to the set temperature level and the equipment temperature is maintained within its normal operating temperature range, so as to realize the function of actively thermally controlling the equipment temperature in the integrated equipment cabin in real time and maintaining the constant temperature of the equipment cabin.

[0043] As a preferred solution, as Figure 3 shown, the outer shell 10 is formed by curing a carbon fiber composite material laminate. The shielding interlayer 101 is a high-permeability magnetic material. The high-permeability magnetic material confines the magnetic induction lines of the external magnetic field inside the outer shell 10, preventing the strong magnetic field outside the equipment cabin from entering the outer shell 10 to interfere with the internal equipment. The shielding interlayer 101 and the outer shell 10 are integrally cured.

[0046] S20. Within the range of the installation space 104, move the loading device 30 along the horizontal surface of the outer edge 103 of the housing until the positions of the plurality of electrical connector plugs 102 correspond to the positions of the plurality of equipment electrical interfaces 301 one by one, and dock the plurality of electrical connector plugs 102 with the inner sides of their respective corresponding plurality of equipment electrical interfaces 301 one by one;
