Description

Technical Field

[0001] This invention relates to the field of gravity energy storage drive system technology, specifically a multi-track train centralized drive system and a gravity energy storage transportation system. Background Technology

[0002] my country's energy structure is undergoing profound changes, and the rapid development of renewable energy is placing higher demands on the power grid. Existing energy storage technologies have limitations, while gravity energy storage projects, as a new type of physical energy storage technology, have advantages such as large capacity, low cost, high efficiency, and long lifespan, making them crucial for solving the problems of renewable energy integration and grid regulation. The basic process of gravity energy storage is as follows: using surplus electricity to drive a motor to lift a heavy object, converting it into high-potential energy for storage; releasing the object generates electricity. Due to its large storage capacity, long output time, and low unit energy cost, it can accurately track grid dispatch commands.

[0003] As a novel type of distributed gravity energy storage system, track-mounted gravity energy storage systems are often built on mountains or mining areas with elevation differences. The upper and lower storage yards are located on flat terrain and connected by a circular track. Multiple drive stations are arranged on the entire circular track. Gravity energy storage trains travel on the circular track using drive stations located below or on both sides of the track. Since multiple flat tracks are arranged to connect to the loading and unloading sections of the upper and lower storage yards, each flat track needs to be equipped with multiple drive stations. However, according to the system scheduling needs, the gravity energy storage trains enter each flat track in an orderly manner through the main track. The multiple flat tracks arranged in parallel will not all have trains entering at the same time, resulting in many drive stations being idle and increasing the construction cost of the energy storage system. Summary of the Invention

[0004] To address the aforementioned shortcomings in existing technologies, the present invention aims to provide a multi-train centralized drive system that enables a single drive system to drive trains on multiple tracks, significantly reducing the number of drive stations and lowering the construction cost of gravity energy storage systems.

[0005] The technical solution adopted by the present invention to achieve the above-mentioned objective is: a multi-track train centralized drive system, including multiple sets of tracks arranged in parallel, a train traveling on the tracks, and a central controller. A centralized drive mechanism is connected to the multiple sets of tracks arranged in parallel. The centralized drive mechanism includes a drive motor, a transmission device, and multiple drive components. The drive motor is poweredly connected to each drive component through the transmission device. The drive components are arranged on one or both sides of the track. The drive components are connected to a translation tensioning device. When the train enters the track, the central controller controls the drive component on the corresponding track side to move closer to the track under the action of the translation tensioning device and make the drive component cooperate with the train, driving the train to travel on the track. The drive motor, transmission device, drive components, translation tensioning device and central controller are electrically connected.

[0006] In the above technical solution, a set of drive components is set between two adjacent tracks.

[0007] In the above technical solution, the driving component adopts the following structure:

[0008] The drive assembly includes a mounting frame and a drive wheel. The drive wheel is rotatably connected to the mounting frame. When the train enters the track, the drive wheel cooperates with the train's drive plate. The axle of the drive wheel is poweredly connected to the transmission device. The mounting frame is mounted on the translational tensioning device.

[0009] The drive wheel is a gear or a friction wheel. When the drive wheel is a gear, the train drive plate is a rack plate that cooperates with the gear. When the drive wheel is a friction wheel, the train drive plate is a plate-shaped structure that cooperates with the friction wheel.

[0010] In the above technical solution, each of the drive wheels is provided with an electromagnetic clutch between itself and the transmission device. The drive wheel axle is connected to the electromagnetic clutch via coupling B, and the electromagnetic clutch is electrically connected to the main controller.

[0011] In the above technical solution, the transmission device adopts the following structure:

[0012] The transmission device includes multiple gearboxes, coupling A, and a drive shaft. The output end of the drive motor is sequentially connected to at least one drive shaft through coupling A. The drive shaft is poweredly connected to at least one gearbox. The power output end of each gearbox is connected to a corresponding drive component.

[0013] The power output end of each gearbox is connected to the electromagnetic clutch of the corresponding drive component.

[0014] In the above technical solution, the tensioning device adopts the following structure:

[0015] The translational tensioning device includes a slide rail, a slider, and a translational telescopic component. The driving component is disposed on the slider, the slider is slidably connected to the slide rail, and the translational telescopic component is connected to one or both sides of the driving component.

[0016] A gravity energy storage transportation system includes multiple sets of tracks arranged in parallel, and a centralized drive mechanism as described above is provided on the multiple sets of tracks.

[0017] The beneficial effects of this invention are:

[0018] By setting up a centralized drive mechanism on multiple parallel tracks, the same drive motor outputs power to the drive component corresponding to each track through a transmission device. Each track has a drive component on one or both sides. When a train enters the track, the main controller controls the drive components on one or both sides of the corresponding track to press against the train, thereby driving the train to travel on the track. Through the centralized drive system of this invention, the same drive mechanism can drive trains on multiple tracks, greatly reducing the number of installations required for a single drive station and also reducing the construction cost of the gravity energy storage transportation system.

[0019] The centralized drive system provided by this invention is suitable for parallel tracks with ample space. Its drive components are set on the side of each track and work in conjunction with the drive plates of conventional trains in gravity energy storage systems. This not only facilitates the installation and maintenance of the drive system, but also eliminates the need for additional design of the train. The transmission connection between the train and the centralized drive system and the drive station in the gravity energy storage system is achieved through the drive plates on both sides of the train.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-5 A centralized drive system for multi-track trains includes multiple sets of parallel-arranged tracks 101, a train 200, and a central controller. (See also...) Figure 1 The main controller controls multiple trains 200 to enter the branch tracks and then the parallel tracks 101 in sequence from the main track. Because the main controller controls the trains 200 to enter the tracks 101 in sequence, it is impossible for multiple trains 200 to enter the parallel tracks 101 at the same time.

[0028] See Figure 1 Multiple sets of parallel tracks 101 are connected to multiple sets of centralized drive mechanisms 300. Along the direction of travel of the train 200, the distance between adjacent sets of centralized drive mechanisms 300 is less than the length of the train 200, ensuring that at least one section of the train 200 is located on and driven by a centralized drive mechanism 300. For details, please refer to... Figure 2 The centralized drive mechanism 300 includes a drive motor 301, a transmission device 302, and multiple sets of drive components 303. That is, the drive motor 301 is powered to each drive component 303 through the transmission device 302. Drive components 303 are provided on one or both sides of the track 101. When the train 200 enters the track 101, the drive component 303 on the corresponding side of the track 101 cooperates with the train 200 to drive the train 200 to travel on the track 101. The drive motor 301, the transmission device 302, and the drive components 303 are controlled by the main controller.

[0029] In this embodiment, in the centralized drive mechanism 300, a drive component 303 can be set on one side of the track 101, and the train 200 is driven by a set of drive components 303 on the side. However, single-side drive may result in unstable train 200 movement.

[0030] Alternatively, drive assemblies 303 can be installed on both sides of track 101, which includes two arrangement methods. One method involves independent drive assemblies 303 arranged on both sides of each track 101, so that the drive assemblies 303 on the corresponding sides work synchronously when a train 200 passes over track 101. The other method, please refer to [link / reference needed]. Figure 2 That is, a set of drive components 303 is set between two adjacent tracks 101. Each set of drive components 303 is connected to a translation tensioning device that drives the drive components 303 to move toward the corresponding track 101. The translation tensioning device is electrically connected to the main controller. The drive components 303 located between two adjacent tracks 101 can be translated to both sides by the translation tensioning device, so that when a train 200 is traveling on the two tracks 101, the drive can be alternately driven. This reduces the number of drive components 303, saves equipment costs, reduces the layout space of the centralized drive mechanism 300, and narrows the distance between parallel tracks 101. When the second scheme is adopted, that is, a set of drive components 303 is set between two adjacent tracks 101, when the main controller needs to control the train 200 to enter the parallel track 101, there is no train 200 on the adjacent track 101 passing through the same set of centralized drive mechanisms 300 at the same time.

[0031] Furthermore, in this embodiment, the transmission device 302 includes multiple gearboxes 3021, couplings A3022, and drive shafts 3023. That is, the output end of the drive motor 301 is sequentially connected to at least one drive shaft 3023 via couplings A3022, and the drive shaft 3023 is poweredly connected to at least one gearbox 3021. Please refer to [link to relevant documentation]. Figure 3 In this embodiment, the output ends on both sides of the drive motor 301 are sequentially connected to two drive shafts 3023 via coupling A3022. Each drive shaft 3023 is connected to two gearboxes 3021, so that one drive shaft 3023 synchronously drives two gearboxes 3021. The number of gearboxes 3021 is the same as the number of drive components 303. The power output end of each gearbox 3021 is connected to the corresponding drive component 303.

[0032] Please see Figure 5The drive assembly 303 includes a mounting bracket 3034 and a drive wheel 3035. The drive wheel 3035 is rotatably connected to the mounting bracket 3034. Each drive wheel 3035 is provided with an electromagnetic clutch 3024 between itself and the transmission device 302. The axle of the drive wheel 3035 is connected to the electromagnetic clutch 3024 through a coupling B3031. The power output end of each gearbox 3021 on the transmission device 302 is connected to the corresponding electromagnetic clutch 3024 of the drive assembly 303. The power of the electromagnetic clutch 3024 is connected to the drive assembly 303. In this way, the drive motor 301 can provide power to each gearbox 3021, and the electromagnetic clutch 3024 controls whether the power is transmitted to the drive assembly 303 through the gearbox 3021.

[0033] In this embodiment, coupling B3031 is a universal coupling.

[0034] In addition, drive plates 201 are provided on both sides of the train 200. Drive wheels 3035 cooperate with drive plates 201. Drive wheels 3035 can be gears or friction wheels. If drive wheels 3035 are gears, the drive plate 201 of the train 200 is a rack plate that cooperates with the gear. When the train 200 enters the track 101, the drive wheel 3035 of the gear meshes with the rack plate on the train 200, and the gear drives the rack plate to make the train 200 move. If drive wheels 3035 are friction wheels, the drive plate 201 of the train 200 is a plate-shaped structure that cooperates with the friction wheel. When the train 200 enters the track 101, after the drive wheel 3035 of the friction wheel comes into contact with the drive plate 201, when the drive wheel 3035 rotates, it can drive or decelerate the train 200 under the action of friction. Other components that can realize the power transmission of drive wheels 3035 and drive plates 201 can be selected, depending on achieving the desired effect.

[0035] Each drive assembly 303 has a mounting bracket 3034 mounted on a translational tensioning device. The translational tensioning device can pull the mounting bracket 3034 to drive the drive wheel 3035 to move closer to or away from the train 200. Specifically, the translational tensioning device includes a slide rail 3033, a slider 3036, and a translational telescopic member 3032. The mounting bracket 3034 of the drive assembly 303 is mounted on the slider 3036, and the slider 3036 is slidably connected to the slide rail 3033. The translational telescopic member 3032 is connected to one or both sides of the drive assembly 303. The slide rail 3033 and the translational telescopic member 3032 can be fixed to the ground by a mounting base. The translational telescopic member 3032 is controlled by a main controller. The main controller controls whether the translational telescopic member 3032 on one or both sides of the track 101 moves closer to the train 200 on the track 101 according to the position of the train 200 entering the track 101.

[0036] The translational telescopic component 3032 can be an electric telescopic cylinder. Of course, other components that can push the mounting frame 3034 can also be selected to achieve the desired effect. Furthermore, in order to reduce the rotational friction of the drive wheel 3035, a bearing seat 3037 is fixedly connected to the mounting frame 3034, and the axle of the drive wheel 3035 is connected to the bearing seat 3037.

[0037] As a preferred embodiment, the drive assembly 303 between the two tracks 101 is provided with translation telescopic members 3032 connected to both sides. The translation telescopic members 3032 can push the mounting frame 3034 to drive the drive wheel 3035 to translate and switch to the tracks 101 on both sides.

[0038] In summary, this embodiment discloses a centralized drive system for multi-track trains. It uses the same drive motor 301 to output power to the drive component 303 corresponding to each track 101 through the transmission device 302. The drive component 303 drives multiple trains 200, greatly reducing the number of installations required for a single drive station.

[0039] Please see Figure 4 Taking the leftmost track 101 in the diagram as an example, for ease of explanation, the drive components corresponding to the leftmost track 101 are numbered from left to right as drive component 1 303 and drive component 2 303. When the main controller controls the train 200 to enter the leftmost track 101 from the branch track, the translation tensioning devices corresponding to drive component 1 303 and drive component 2 303 move it closer to the predetermined track 101. At the same time, the electromagnetic clutches 3024 corresponding to drive component 1 303 and drive component 2 303 are engaged and disengaged, and the drive motor 301 can transmit power to the drive wheel 3035 through the gearbox 3021 and the electromagnetic clutch 3024. This ensures that the rotational speed of the drive wheel 3035 matches the speed of the train 200. When the train 200 enters the drive area, the translation tensioning device presses the drive wheels 3035 of the first drive assembly 303 and the second drive assembly 303 against the drive plate 201 of the train 200. Due to the matching speed of the drive wheels 3035 and the train 200, the train 200 and the drive wheels 3035 work smoothly together. Under the action of friction, the drive wheels 3035 continue to carry the train 200 forward at a steady speed until the last carriage of the train 200 leaves the drive assembly 303. Then, the electromagnetic clutches 3024 of the first drive assembly 303 and the second drive assembly 303 open and disconnect the power transmission.

[0040] The operation of the drive assembly 303, transmission device 302, translation tensioning device, and the selection of the train 200's travel track are all controlled by the main controller. When the train 200 enters the selected track 101, the main controller simultaneously sends a control command to the centralized drive mechanism 300. The drive assemblies 303 on both sides of the corresponding track 101 move closer to the selected track 101 under the action of the translation tensioning device, and the electromagnetic clutch 3024 is closed. The transmission device 302 transmits power to the drive wheel 3035 through the electromagnetic clutch 3024, thereby driving the train 200 to move. When no train 200 enters the other tracks 101, the electromagnetic clutch 3024 of the corresponding drive assembly 303 is opened, disconnecting the power output of the drive motor 301 and the transmission device 302. The translation tensioning devices are all in a working standby state.

[0041] A gravity energy storage transportation system includes multiple parallel transportation tracks, on which the aforementioned centralized drive mechanism 300 is installed. The centralized drive mechanism 300 is mainly used in the gently sloping track group of the gravity energy storage transportation system.
