Description
Technical Field
[0001] The present invention relates to the technical field of electromagnetic railways, and particularly to a water inlet head for electromagnetic railway passenger cars. Background Art
[0002] As a new type of rail transit system, electromagnetic railways use electromagnetic force instead of traditional wheel-rail contact to achieve the suspension and propulsion of trains. With the continuous development of this technology, new challenges and requirements have been put forward in the design, manufacture, and operation of electromagnetic railway passenger cars. In electromagnetic railway passenger cars, the water supply system usually adopts a fixed water inlet pipe interface. When the train stops at the platform, water is introduced into the car through mechanical connection or hose connection.
[0003] For railway passenger cars, including EMUs, water is injected manually by inserting a water pipe into the water inlet head on the car body and then turning on the water source. Both turning on and off the water source and inserting and removing the pipe head require manual operations. The stop time of passenger trains at stations is relatively short. The shortest stop time at water supply stations is only 6 minutes. For trains with a dozen carriages that require water supply, additional workers must be added, which has a certain impact on train operation and stop time. At present, after the water supply is completed and the train starts, the pipe head is not removed in time, resulting in the train starting with the pipe head attached, which has a serious impact on train operation safety. At the same time, for some devices, manual operation is required to wind up the water pipe, which affects the use efficiency.
[0004] Therefore, we propose a water inlet head for electromagnetic railway passenger cars to solve the above problems. Summary of the Invention

Specific embodiments The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0022] A device housing 4 is fixed at the top of the placement platform 1, and a cover plate 5 is hinged at the top of the device housing 4; According to the attached Figure 2As shown, a water supply device is provided in the device housing 4. The water supply device includes: a water source well 20, a water pipe 6, a 24V power supply 12, a power remote control 13, an electric water valve 11, and an electromagnetic water inlet pipe head 8. The water pipe 6 is fixedly inserted into the device housing 4, and one end of the water pipe 6 is connected to the water source well 20. An electromagnetic water inlet pipe head 8 is installed at the other end of the water pipe 6. An electric water valve 11 is installed on the surface of the water pipe 6 inside the device housing 4. One end of the electric water valve 11 is connected to the 24V power supply 12 through a wire, and the other end of the 24V power supply 12 is connected to the power remote control 13 through a wire. By energizing the electromagnetic coil of the electromagnetic water inlet pipe head 8, the electromagnetic water inlet pipe head 8 is connected to and separated from the bus water inlet, eliminating the need for manual operation one by one and reducing the water injection time.
[0023] According to the appendix Figure 2 As shown, the electric water valve 11, the 24V power supply 12, and the power remote control 13 are all provided in the device housing 4. The wires required for connection pass through the device housing 4, enabling the smooth operation of the water supply device. It is started and closed by power and controlled wirelessly, improving the convenience of use.
[0024] According to the appendix Figure 2 As shown, the electromagnetic water inlet pipe head 8 is made of soft magnetic material silicon steel designed according to the size of the bus water inlet pipe head, which can just fit all pipe head models. The connection between the electromagnetic water inlet pipe head 8 and the bus water inlet is that the copper coil of the silicon steel generates a strong magnetic force to adsorb the water inlet after being energized. At the same time, the electric water valve 11 is opened to inject water into the vehicle body. After the water injection is completed, the power of the power remote control 13 is cut off, and the electromagnetic water inlet pipe head 8 is separated from the bus water inlet, and the electric water valve 11 is closed.
[0025] According to the appendix Figure 4 As shown, the electromagnetic water inlet pipe head 8 includes a connecting pipe 81. The bottom end of the connecting pipe 81 is slidably inserted into one end of the water pipe 6. The surface of the connecting pipe 81 is provided with an inclined angle, which facilitates the connection between the connecting pipe 81 and the water pipe 6. The inclined angle design increases the contact area at the pipe connection, thereby enhancing the connection strength and stability. It can thus withstand high-pressure or high-flow-rate water, reduce the resistance of the fluid in the pipe, improve the fluid flow efficiency, be easier to align during installation, reduce the installation difficulty and time, and also make the pipe easier to disassemble during maintenance or replacement, improving the maintenance convenience and helping to reduce the leakage risk. The inclined angle design can improve the sealing performance at the connection and reduce the leakage risk of liquid or gas.
[0026] According to the appendix Figure 4As shown, the top end of the connecting pipe 81 is fixedly connected and communicated with a convex end 82, and a wire pressing plate 86 is fixedly sleeved on the surface of the convex end 82. The bottom end of the wound copper wire 87 passes through and out of one end of the wire pressing plate 86. The wound copper wire 87 is wound around the surface of the wire pressing plate 86. The wire pressing plate 86 is made of PVC material. One end of the wound copper wire 87 passes into the wire pressing plate 86 and then winds around the wire pressing plate 86. After winding, it passes out of the inlet end of the wire pressing plate 86 again, fixing and winding the wound copper wire 87 on the surfaces of the wire pressing plate 86 and the winding end 86, reducing the falling off or loosening of the wire, ensuring the stability and safety of the circuit connection, reducing the risk of damage to the wire due to external pulling or abrasion, extending the service life of the wire, and also reducing the electric shock accidents caused by electric leakage, improving the safety of use.
[0027] According to the appendix Figure 4 As shown, the top end of the convex end 82 is fixedly connected and communicated with a winding end 83, and a pipe orifice 84 is fixed at the top end of the winding end 83. A cap head 85 is fixedly sleeved on the surface of the pipe orifice 84. The connecting pipe 81, the convex end 82, the winding end 83 and the pipe orifice 84 are all made of silicon steel material, and the cap head 85 is made of silica gel material. The soft magnetic material silicon steel has a high magnetic permeability, which can efficiently guide the magnetic flux, thereby reducing energy loss. Compared with pure iron, the iron loss (hysteresis loss and eddy current loss) of silicon steel is lower, which makes it particularly useful in high-frequency applications. It also has good magnetic saturation characteristics and can reach magnetic saturation at a relatively high magnetic induction intensity, which is very important for applications requiring high magnetic flux density. It has good workability and can be stamped into various shapes, suitable for manufacturing small and complex electromagnetic components. Although the price of silicon steel is relatively high, due to its excellent performance, in the long run, it provides better cost-effectiveness in many applications. With the progress of technology, the production process of modern silicon steel is more environmentally friendly, reducing the impact on the environment. The silica gel material has excellent elasticity and aging resistance, and also has good waterproof performance, good sealing performance, reducing the gap at the connection, and maintaining its physical and chemical properties during long-term use.
[0028] According to the appendix Figure 4 As shown, the wound copper wire 87 is wound around the surface of the winding end 83, and the wound copper wire 87 uses a copper wire with a diameter of φ1mm, the winding length is 22 meters, and the number of turns is 272. The wound copper wire 87 is coated with epoxy resin ab glue on the surface of the winding end 83. The winding length and the number of turns have been tested many times to make it more reliable and safe during use. The epoxy resin ab glue material can provide very high bonding strength, can withstand the injection of a large amount of water or the structural bonding of external forces, and can also resist the erosion of water, and has good electrical insulation, reducing the occurrence of electric leakage.
[0029] On both sides of the top of the placement platform 1, fixed plates 9 are fixed. And on the surface of the fixed plate 9, a movable column 19 is hinged. Square grooves 2 are respectively fixed on the movable column 19 and the top of the fixed plate 9, and the square grooves 2 are fixed by bolts 7. A rotating rod 18 is movably inserted in the middle of the fixed plate 9 and the movable column 19. And a second disc 16 is fixedly sleeved on the surface of the rotating rod 18. On one side of the second disc 16, a fixed disc 15 is fixed by a fixed column 14. On the other side of the fixed disc 15, a first disc 10 is fixed by a fixed column 14. Square grooves 3 are formed on the surfaces of the first disc 10 and the second disc 16. One end of the rotating rod 18 is fixed with a rotating handle 17.
[0030] According to the attached Figure 6 As shown, both ends of the water pipe 6 are respectively wound on the surface of the fixed column 14. Both ends of the water pipe 6 are movably engaged with the second disc 16, which improves the winding efficiency and stability and reduces the occurrence of falling off.
[0031] According to the attached Figure 7 As shown, there are two groups of electromagnetic upper water pipe heads 8 and movable columns 19 symmetrically arranged. The two groups of electromagnetic upper water pipe heads 8 and movable columns 19 are respectively hinged. The middle of the two groups of electromagnetic upper water pipe heads 8 and movable columns 19 is movably inserted with both ends of the rotating rod 18. Rubber pads are laid on the inner sides of the two groups of electromagnetic upper water pipe heads 8 and movable columns 19. Rubber has good friction, which reduces the displacement and rotation during use, can maintain the storage effect, and can also make the rotating rod 18 more stable during use, reducing the distance between the fixed plate 9 and the movable column 19.
[0032] According to the attached Figure 8 As shown, there are multiple groups of second discs 16. The multiple groups of second discs 16 are arranged in a circumferential and equidistant manner, which is suitable for the water pipes 6 at different positions to be used, improving the flexibility of use.
[0033] The water pipe 6, electromagnetic upper water pipe head 8, electric water valve 11, 24V power supply 12 and power remote control 13 used in this application are products that can be directly purchased on the market. Their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be described in detail here.
[0034] Working principle: When in use, 01 is fixed at the corresponding position on the railway. One end of the water pipe 6 is placed into the water source well 20. The external power supply provides the power source for the whole. Press the external remote control to start the power remote controller 13 and the 24V power supply 12. The 24V power supply 12 controls the electric water valve 11 and the electromagnetic upper water pipe head 8 through the circuit. After the copper coil of silicon steel on the electromagnetic upper water pipe head 8 is energized, a strong magnetic force is generated to adsorb the upper water port. At the same time, the electric water valve 11 is opened to inject water into the vehicle body. After the water injection is completed, the power is turned off through the external remote control power remote controller 13, the electromagnetic upper water pipe head 8 is separated from the upper water port of the passenger car, and the electric water valve 11 is closed, so that the electromagnetic upper water pipe head 8 is separated from the upper water port of the passenger car; When not in use, both ends of the water pipe 6 are respectively clamped into the corresponding square grooves 3 of the two groups of the first disc 10 and the second disc 16. Then rotate the rotating handle 17 to drive the rotating rod 18, the second disc 16, the fixed disc 15, the fixed column 14 and the first disc 10 to rotate simultaneously, so that both ends of the water pipe 6 are wound around the surface of the fixed column 14 for storage; When it is necessary to move out and tighten the rotating rod 18, the moving columns 19 on one side of the two groups of fixing plates 9 are rotated in sequence to close or separate the fixing plates 9 and the moving columns 19, and then the bolt 7 is taken out of the square groove 2, or the square groove 2 is fixed by the bolt 7.
[0035] The above is the whole working principle of the present invention.
