Description

Technical Field

[0002] Electric energy storage encompasses various methods, including mechanical energy storage, electrochemical energy storage, electromagnetic energy storage, thermal energy storage, and chemical energy storage. Electrochemical energy storage most commonly utilizes a large number of batteries for charging and discharging, while mechanical energy storage includes common methods such as pumped hydro storage, gravity energy storage, and compressed air energy storage. Gravity energy storage works by using a mass block as the energy storage medium. During the storage phase, a motor lifts the mass block to a higher position, converting electrical energy into gravitational potential energy. During the power generation phase, the mass block is lowered to drive the motor, converting gravitational potential energy into electrical energy output. Currently, in scenarios such as high-altitude mines, the cost of laying transportation lines is too high, and some harsh environments even make road construction impossible, necessitating the construction of energy storage systems that transport heavy objects via rail. Therefore, mountain slope-type gravity energy storage systems have the advantages of large energy storage capacity and low construction cost, and have broad application prospects. However, existing rail-mounted gravity energy storage devices suffer from poor compatibility; the tracks are difficult to adapt to complex terrain, affecting the stability of the rail-mounted gravity energy storage devices.

[0025] By setting up a transmission system 200 and a reversible unit 320, during off-peak electricity demand periods, the reversible unit 320 transports the heavy object 140 from the first warehouse 110 to the second warehouse 120 located at a higher elevation, ensuring that the track-type gravity energy storage device can fully utilize electrical energy and perform gravity energy storage. During peak electricity demand periods, the heavy object 140 located in the second warehouse 120 is transported by gravity to the first warehouse 110 located at a lower elevation via the transport track 100, driving the reversible unit 320 to generate electricity and supply it to the power grid to meet power demand and ensure the stability and energy storage efficiency of the track-type gravity energy storage device. By setting up the transport track 100 and the transmission system 200, the first transmission unit 210 and the second transmission unit 310 cooperate to drive the transport body 220 or the reversible unit 320 to operate. The second transmission unit 310 is distributed on the track body 130 to adapt to different terrains, improving the operational stability and compatibility of the track-type gravity energy storage device.

[0026] Reference Figure 1 and Figure 2 The heavy object 140, the transport body 220 and the first transmission part 210 are made as one piece. This structure makes it easy for the heavy object 140 to be stably transported on the track body 130, effectively simplifying the structure of the transport track 100 and the transmission system 200, reducing the construction cost of the track-type gravity energy storage device and improving the construction efficiency of the track-type gravity energy storage device.

[0027] Reference Figure 3 and Figure 4 The heavy object 140 is fixed to the transport body 220 by a support plate 230.

[0030] In some embodiments, the distribution density of the first rotating wheel 311 is determined by the slope of the track body 130. This structure ensures that the track body 130 can adapt to different terrains. When the slope of the track body 130 is large, the distribution density of the first rotating wheel 311 on the track body 130 is large, so as to ensure that the first rotating wheel 311 can stably drive the transport body 220 to move up and down, avoid the transport body 220 from derailing, and improve the operational stability of the track-type gravity energy storage device.

[0031] Reference Figure 5 In some embodiments, multiple adjacent second transmission units 310 are connected to the reversible unit 320 via connecting parts 330, which are composed of at least one type of steel belt, belt, or gear set. By providing connecting parts 330, the transmission efficiency between the reversible unit 320 and the second transmission units 310 can be effectively guaranteed, thereby improving the energy storage efficiency of the track-type gravity energy storage device.

[0032] In some embodiments, multiple reversible units 320 are evenly distributed along the track body 130. By providing multiple reversible units 320, the transmission efficiency between the second transmission unit 310 and the reversible units 320 can be guaranteed, avoiding the increased construction costs caused by equipping each second transmission unit 310 with an independent reversible unit 320, reducing power loss, and improving the energy storage efficiency of the track-type gravity energy storage device. Of course, in other embodiments, the multiple reversible units 320 may not be evenly distributed along the track body 130. In practical applications, an adaptive layout can be made according to the slope and curvature of the track body 130 to ensure the connection stability between the reversible units 320 and the second transmission unit 310.

[0033] In some embodiments, the connecting part 330 includes a second rotating wheel 331 and a third rotating wheel 332.

By providing the drive device 241 and the tilt sensor 242, the adjustment assembly 240 can rotate one side of the support plate 230 according to the reading of the tilt sensor 242, thereby ensuring that the support plate 230 remains horizontal and improving the stability of transporting the heavy object 140.

[0035] In some embodiments, the drive device 241 is a push rod, and the drive end of the drive device 241 is connected to the support plate 230. The push rod has the advantages of large thrust, high speed and long service life. The use of a push rod in the drive device 241 can effectively ensure the working stability of the adjustment component 240 and the service life of the track-type gravity energy storage device.

[0036] In some embodiments, the height difference between the first warehouse 110 and the second warehouse 120 is greater than 100 meters. This height difference ensures the flexibility of the location selection of the first warehouse 110 and the second warehouse 120, and also makes full use of the height difference between the first warehouse 110 and the second warehouse 120 to improve the energy storage efficiency of the track-mounted gravity energy storage device.

[0037] In some embodiments, by setting up two track bodies 130, one for transporting goods from bottom to top and the other for transporting minerals from top to bottom, the transport body 220 can be immediately transferred to the other track body 130 after transporting goods from bottom to top and then sent down the mountain, thereby improving the transport efficiency of the track-type gravity energy storage device.

[0038] Reference Figure 6 In some embodiments, adjacent transport bodies 220 are connected by connectors 250. By providing connectors 250, the connection stability between the connected transport bodies 220 is ensured, and multiple transport bodies 220 can reciprocate along the track body 130, preventing displacement or detachment of the transport bodies 220 and the load 140.

[0039] The working principle of this utility model will be further explained below.

[0040] During construction, a first warehouse 110 and a second warehouse 120 are first set up at suitable locations on the high and low sides of the mine, respectively. Then, a track body 130 and a second transmission unit 310 are laid between the first warehouse 110 and the second warehouse 120, with first rotating wheels 311 installed on the track body 130 according to the slope. Next, a reversible unit 320 and a connecting part 330 are installed, allowing the reversible unit 320 to drive a transport body 220 with insertion holes 211 and adjustment components 240 and a load 140 to move back and forth between the first warehouse 110 and the second warehouse 120 via a third rotating wheel 332, a second rotating wheel 331, and a first rotating wheel 311. The distribution density of the first rotating wheels 311 is determined by the slope of the track body 130 to ensure that, at steeper slopes, a higher density of first rotating wheels 311 can stably pull the transport body 220 up and down. Specifically, as shown... Figure 1 and 2 As shown, the second transmission unit 310 includes a plurality of first rotating wheels 311, each with a first protruding tooth 312; the first transmission unit 210 has insertion holes 211 that mate with the first protruding teeth 312, the insertion holes 211 being located at the bottom of the transport body 220; the distribution density of the first rotating wheels 311 is determined by the slope of the track body 130; to ensure ease of maintenance, the reversible unit 320 is distributed on one side of the first rotating wheels 311; or as... Figure 3 Multiple reversible units 320 are evenly distributed along the track body 130 to reduce power loss and improve the energy storage efficiency of the track-type gravity energy storage device. In practical applications, the reversible units 320 can be connected to the third rotating wheel 332 via steel belts, belts, or gear sets. The third rotating wheel 332 and the second rotating wheel 331, as well as the second rotating wheel 331 and the first rotating wheel 311, can also be connected via steel belts, belts, or gear sets. The specific connection method can be determined according to the installation environment, enabling flexible installation of the second transmission unit 310 and the first transmission unit 210. In addition, a support plate 230 and an adjustment assembly 240 are installed on the transport body 220. An angle sensor 242 is installed on the support plate 230, and the drive end of the drive device 241 is connected to the support plate 230. In practical applications, to ensure energy storage efficiency, the height difference between the first warehouse 110 and the second warehouse 120 is greater than 100 meters to fully utilize the height difference between the mountains and improve the working efficiency of the track-type gravity energy storage device. The installation of the track-type gravity energy storage device is completed in this way. The distribution density of the second transmission unit 310 is determined by the slope of the track body 130, so that the track body 130 can adapt to different mountain terrains and avoid the transportation body 220 and the heavy object 140 from falling off or getting stuck during transportation. This effectively simplifies the structure of the track-type gravity energy storage device and saves the construction cost of the track-type gravity energy storage device.

[0041] During operation, peak and off-peak electricity consumption periods refer to the load status of the external public power grid. Peak electricity consumption periods are the power generation phase of the track-mounted gravity energy storage device, while off-peak periods are the energy storage phase. Specifically, during off-peak periods, the reversible unit 320, in drive mode, drives the transport body 220 upward along the track body 130 via the second transmission unit 310 and the first transmission unit 210 to ensure that the track-mounted gravity energy storage device can fully utilize electrical energy and perform gravity energy storage. During peak electricity consumption periods, the reversible unit 320, in power generation mode, utilizes the downward potential energy of the weight 140 to drive or rotate the first and second transmission units 210 to generate electricity for storage or grid connection, thereby meeting power demand and ensuring the stability and energy storage efficiency of the track-mounted gravity energy storage device. During the transport of heavy objects 140 by the transport body 220, in order to prevent the support plate 230 from tilting during transport, the adjustment component 240 can rotate one side of the support plate 230 according to the reading of the tilt sensor 242 to ensure that the support plate 230 remains horizontal and improve the stability of transporting heavy objects 140. Therefore, the transport body 220 can transport automobiles, minerals and other items, and improve the compatibility and working stability of the track-type gravity energy storage device.

[0042] An embodiment of this application discloses a track-type gravity energy storage device. By configuring a conveying system 200 and a reversible unit 320, during off-peak electricity demand periods, the reversible unit 320 conveys heavy objects 140 from a first warehouse 110 to a higher-level second warehouse 120, ensuring the track-type gravity energy storage device can fully utilize electrical energy and perform gravity energy storage. During peak electricity demand periods, heavy objects 140 located in the second warehouse 120 are conveyed by gravity to the lower-level first warehouse 110 via a transport track 100, driving the reversible unit 320. Group 320 generates electricity and transmits it to the power grid to meet power demand and ensure the stability and energy storage efficiency of the track-mounted gravity energy storage device. By setting up a transport track 100 and a transmission system 200, the first transmission unit 210 and the second transmission unit 310 cooperate to drive the transport body 220 or the reversible unit 320. The second transmission units 310 are distributed on the track body 130 to adapt to different terrains, improving the operational stability and compatibility of the track-mounted gravity energy storage device. By setting up a first tooth 312 and a socket 211, the first transmission unit 210 is inserted into the socket 211 through the first tooth 312 to connect with the second transmission unit 310, ensuring the stability and energy storage efficiency of the track-mounted gravity energy storage device. By setting up a steel belt, belt, or gear set, the transmission efficiency between the reversible unit 320 and the second transmission unit 310 can be effectively ensured, improving the energy storage efficiency of the track-mounted gravity energy storage device. By setting up a second rotating wheel 331 and a third rotating wheel 332, multiple first rotating wheels 311 can be stably connected through the second rotating wheels 331. The third wheel 332 is connected to the drive end of the reversible unit 320, ensuring the stability and flexibility of the connection between the transport body 220 and the reversible unit 320, and improving the installation convenience and compatibility of the track-type gravity energy storage device. By setting the drive device 241 and the tilt sensor 242, the adjustment component 240 can drive one side of the support plate 230 to rotate according to the reading of the tilt sensor 242, so as to ensure that the support plate 230 remains in a horizontal state and improve the stability of the transport of the heavy object 140.
