However, due to the extremely high erection cost and daily maintenance cost of the high-voltage catenary, it is not suitable for some short-distance transportation lines. At the same time, with the development and maturity of battery technology, energy storage trains have gradually been put into use.

[0003] The working principle of an energy storage train is mainly that the train is equipped with power batteries, and the power batteries provide power for the train. Charging piles are installed at fixed positions such as stations, and certain charging equipment is used to charge the power batteries, which can reduce the erection cost and maintenance cost of the catenary. Currently, there is an urgent need for a pantograph suitable for charging energy storage trains. Summary of the Utility Model

[0023] In order to solve the technical problems of energy storage train charging in the prior art, the present application provides a pantograph for charging an energy storage train.

[0024] See Figure 1 、Figure 2 and Figure 3 For the pantograph for charging an energy storage train, it includes: a mounting plate 4, one set or more than one set of positive pantographs 3 and negative pantographs 5; one end of the positive pantograph 3 and the negative pantograph 5 is connected to the mounting plate 4, and the other ends are respectively arranged corresponding to the positive conductive rail 2 and the negative conductive rail 6 on the train 1, and can realize contact or separation from the conductive rail; the positive pantograph 3 and the negative pantograph 5 are symmetrically arranged, and each pantograph includes: a pantograph mounting seat 7 mounted on the mounting plate 4, a rear end 8 of a cantilever hinged to the pantograph mounting seat 7, an insulator 11 connected to the rear end 8 of the cantilever, a front end 9 of the cantilever connected to the insulator 11, and a bow head slider 10 hinged to the front end 9 of the cantilever; the positive pantograph 3 and the negative pantograph 5 contact or separate from the positive conductive rail 2 and the negative conductive rail 6 through the bow head slider 10; a guide rail 14 is arranged at the middle position of the mounting plate 4, a guide hole 141 is arranged along the symmetrical center line position of the positive pantograph 3 and the negative pantograph 5 on the guide rail 14, push rods 15 are respectively hinged on the rear ends 8 of the cantilevers of the positive pantograph 3 and the negative pantograph 5, and the other ends of the two push rods 15 are hinged through a pull pin 13; the pull pin 13 is placed in the guide hole 141 and can slide up and down along the guide hole 141; both ends of a spring 12 are respectively hinged at the symmetrical positions in the middle regions of the two push rods 15, and it further includes an electric pull rope 16, the rope of which is connected to the pull pin 13, and the electric pull rope 16 is controlled by a control system to elongate and retract the pull rope.

[0025] Using a separately arranged diversion wire, the current is directly diverted from the charging pile to the front end 9 of the cantilever of the positive pantograph 3, then to the bow head slider 10, transmitted to the battery system inside the train 1 through the positive conductive rail 2, and then the current returns through the negative conductive rail 6 and the negative pantograph 5 to charge the power battery of the train 1.

[0026] In this embodiment, for the pantograph for charging an energy storage train, through the control of the electric pull rope 16, the positive pantograph 3 and the negative pantograph 5 can contact or separate from the positive conductive rail 2 and the negative conductive rail 6 on the train; the cantilever structure of the pantograph enables good electrical conductivity when contacting the conductive rail, and at the same time the spring 12 provides a thrust to ensure stable contact between the pantograph and the conductive rail; the pull pin 13 slides in the guide hole 141 in the guide rail 14, and the up and down position of the pantograph can be adjusted through the operation of the electric pull rope 16, thereby controlling its contact state with the conductive rail.

[0027] The pantograph for charging an energy storage train in this embodiment has a simple structure and convenient operation, can stably and reliably contact the conductive rail on the train, and thus ensures the smooth progress of the charging process.

[0028] In a possible embodiment, two sets of positive pantographs 3 and negative pantographs 5 are provided.

[0029] By increasing the number of pantographs on the positive and negative sides, the overall stability of the pantograph can be maintained, and the charging efficiency and reliability of the train can be improved. The two pantographs can work in parallel to ensure a more stable charging process.

[0030] In a possible implementation, a fixed pulley 17 is installed below the mounting plate 4 corresponding to the upper side of the pull pin 13; the rope of the electric pull rope 16 is connected to the pull pin 13 through the fixed pulley 17.

[0031] By arranging the fixed pulley 17 below the mounting plate 4, the transmission path of the electric pull rope 16 is optimized, enabling the rope to drive the pull pin 13 to slide up and down more smoothly. This can effectively reduce rope wear and improve the operating stability of the pantograph.

[0032] In a possible implementation, two guide rails 14 are provided at the symmetrical midline positions corresponding to each group of positive pantographs 3 and negative pantographs 5, and the spring 12 is arranged in the middle of the two guide rails 14.

[0033] In this setting, the two guide rails 14 respectively provide guiding support for the positive and negative pantographs, and the spring 12 is placed between the two guide rails, which can evenly distribute the force and ensure the smooth sliding of the pantograph within the guide rails.

[0034] The double-guide-rail structure further enhances the stability of the pantograph, avoiding problems such as offset or uneven force that may be caused by a single guide rail. The spring 12 in the middle position makes the resilience of the pantograph more uniform, thereby improving the contact stability and reliability.

[0035] In a possible implementation, the pull pin 13 is placed in the guide holes 141 of the two guide rails 14.

[0036] By placing the pull pin 13 in the guide holes 141 of the two guide rails 14, the sliding path of the pantograph is clearer and the sliding process is more stable, avoiding lateral offset during sliding and improving the operating accuracy of the system.

[0037] In a possible implementation, two springs 12 are provided and are simultaneously hinged at symmetrical positions in the middle area of the push rod 15, and the two springs 12 are placed on both sides of the push rod 15.

[0038] The double-spring structure can evenly apply force to the push rod 15, making the force on the pantograph more uniform throughout the operation process, and avoiding problems of uneven force and unstable sliding that may be caused by a single spring.

[0039] Using two springs 12 not only improves the operating stability of the pantograph but also extends the service life of the spring, further enhancing the reliability and durability of the system.

[0040] In a possible implementation, the electric drawstring 16 is installed at the bottom of the mounting plate 4.

[0041] Installing the electric drawstring 16 at the bottom of the mounting plate 4 can save space, simplify the overall structural design, and at the same time help to lower the center of gravity and increase the stability of the system.

[0042] The bottom-mounted method optimizes the overall structural design of the pantograph, improves the space utilization rate, and enhances the stability and durability of the system.

[0043] The pantograph for charging an energy storage train according to an embodiment of the present utility model is specifically described as follows:

[0044] As Figure 1 shown, the energy storage train charging system includes an energy storage train 1, a positive conductive rail 2, a negative conductive rail 6, a positive pantograph 3, a negative pantograph 5, and a mounting plate 4 for mounting the power receiving rail.

[0045] Using a separately provided diversion wire, the current is directly diverted from the charging pile to the front end 9 of the cantilever of the positive pantograph 3, then to the bow head slide plate 10, and transmitted to the battery system inside the train 1 through the positive conductive rail 2, and then the current returns through the negative conductive rail 6 and the negative pantograph 5 to charge the power battery of the train 1.

[0046] The structure of the positive pantograph or the negative pantograph is as Figure 2 shown. The positive pantograph and the negative pantograph adopt a symmetrical structure. The pantograph includes a cantilever rear end 8, a cantilever front end 9, a bow head slide plate 10, an insulator 11, and a push rod 15. The push rods on the left and right sides are hinged through a pull pin 13. The pull pin 13 slides up and down in the guide hole 141 of the guide rail 14 to ensure the symmetrical movement of the pantographs on the left and right sides. The cantilever rear end 8 is hinged to the charging pantograph mounting seat 7. The cantilever rear end 8 and the cantilever front end 9 are bolted to the insulator 11; the bow head slide plate 10 is hinged to the cantilever front end 9 to ensure that the slide plate plane always remains horizontal at any height; the spring 12 is in a stretched state. The cantilever rear end 8 and the cantilever front end 9 are respectively connected to the push rods 15 on the left and right sides. The spring force provides the contact force between the bow head slide plate 10 and the positive conductive rail 2 and the negative conductive rail 3, ensuring the contact stability between the slide plate and the conductive rail during charging.

[0047] Lowering process: As Figure 3 shown, under the action of the fixed pulley 17, the rope of the electric drawstring 16 makes the rope vertically downward and is fixed to the pull pin 13. During charging, the length of the electric drawstring increases uniformly, and the charging pantograph rotates and descends to the working position at a constant angular velocity under the action of its own gravity and spring tension, and stably contacts the conductive rail.

[0048] Bow-raising process: The rope of the electric drawstring 16 is retracted at a constant speed and acts on the draw pin 13. At this time, the rope overcomes the spring elastic force and the gravity of the pantograph, so that the draw pin 13 moves upward along the guide rail 14, driving the push rod 15 to move, and finally pulling up the pantograph.

[0049] The pantograph for charging the energy storage train of the present utility model has the advantages of simple structure and low production cost. In terms of operation, by controlling the elongation and contraction of the electric drawstring, the lifting movement of the pantograph can be realized, which is suitable for the charging of short-distance energy storage trains. Compared with the socket charging method of electric vehicles, it is safe, reliable and easy to operate.

[0050] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and the key point of each embodiment is to illustrate the differences from other embodiments. For the same and similar parts between the various embodiments, reference can be made to each other.

[0051] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them; although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still can modify the specific implementation manners of the present application or perform equivalent replacements on some technical features; without departing from the spirit of the technical solutions of the present application, they should all be covered within the scope of the technical solutions claimed in the present application.
