Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to a rail cable car transportation system for high and steep slope environments. Background Art

[0002] Over 20 provinces, municipalities, and autonomous regions in my country have introduced policies for energy storage deployment, with storage allocations ranging from 10% to 20% and deployment durations from 2 to 4 hours. Between 2020 and 2022, this policy has already generated significant demand for energy storage capacity, becoming the single biggest driver of energy storage development in China. Gravity energy storage offers the advantages of low construction and maintenance costs, high conversion rates, a short construction cycle (1.5-2 years), abundant site resources, and a long lifespan. It utilizes surplus electricity to lift heavy objects from a low location to a high location, converting electrical energy into potential energy. When discharge is required, the potential energy is converted back into electrical energy. Existing pumped hydro storage is essentially gravity energy storage, using "flowing" water as the storage medium to convert gravitational potential energy into electrical energy. However, pumped hydro storage has a long construction cycle and is not practical. Utility Model Content

[0007] In a possible implementation, the cable car track groups are three groups, including a first cable car track group, a second cable car track group, and a third cable car track group;

[0008] The first cable car track group, the second cable car track group and the third cable car track group are arranged side by side, and the lengths of the power generation and transportation pipelines of the first cable car track group, the second cable car track group and the third cable car track group gradually increase, and the lengths of the unloading tracks of the first cable car track group, the second cable car track group and the third cable car track group gradually increase.

There is a height difference between the top of the mountain and the bottom of the mountain. When a transport trolley is used to transport heavy objects on the transportation track, a potential energy difference is generated when transporting from the top of the mountain to the bottom of the mountain. Therefore, the potential energy generated by the transport trolley carrying heavy objects when sliding from the top of the mountain to the bottom of the mountain can be collected and converted into electrical energy to provide power for the operation of the transportation track. Specifically, the mountain top yard track is located at the top of the mountain, the mountain bottom yard track is located at the bottom of the mountain, and the power generation transportation track is connected between the mountain top yard track and the mountain bottom yard track. By arranging a gravity potential energy generator on the power generation transportation track, the gravity potential energy generated by the transport trolley relative to the transportation track is converted into electrical energy, and collected through a substation, and the collected electrical energy is transmitted to the transportation track for use, thereby avoiding the waste of the potential energy of the transport trolley and reducing the overall cost of use. Not only that, the two cable car tracks form a cable car track group. During the transportation of goods, the mountaintop yard track, power generation transport track and mountain bottom transport track of each group of cable car tracks are close to each other, which is convenient for management. In each cable car track group, one transport track is connected to an unloading track and connected to the same unloading area, thereby saving floor space, facilitating the unloading of heavy blocks, and improving the overall unloading efficiency.

[0028] See Figure 1 and Figure 2The rail cable car transportation system for a high and steep slope environment of the embodiment of the present application includes: a cable car track and an unloading track 140. The two cable car tracks constitute the cable car track group, which is laid on the mountain. Multiple cable car track groups are arranged side by side, and the cable car track includes a transport track, a transport trolley 1114, a transport trolley 1114 and a substation 1116. The transport track is laid on the mountain, and the transport track is located at the top of the mountain as the mountaintop yard track 1111, and is located at the bottom of the mountain as the mountain bottom yard track 1113. The transport trolley 1114 is set on the transport track and slides along the track of the transport track. , and the transport trolley 1114 is provided with a carrying platform, suitable for carrying goods, the gravity potential energy generator 1115 can generate electricity under the action of the gravity potential energy of the transport trolley 1114, the substation 1116 is set at the bottom of the mountain, connected to the gravity potential energy generator 1115 and the power grid respectively, and is suitable for transmitting the electricity generated by the gravity potential energy generator 1115 to the power grid, the unloading rail 140 is connected to the mountain bottom yard rail 1113 of the transport rail, and the number of unloading rails 140 matches the number of transport rails, and multiple unloading rails 140 are arranged side by side and connected to the same unloading area 150.

[0029] Among them, the driving device of the gravity potential energy generator 1115 is a roller, which is connected to the cable corresponding to the transport track. The cable drives the roller to roll and rotate. The rotating roller can convert kinetic energy into electrical energy through the gravity potential energy generator 300.

[0030] In this embodiment, the transport track of the cable car track is laid on a mountain with a height difference, and is used to transport goods between the top of the mountain and the bottom of the mountain. There is a height difference between the top of the mountain and the bottom of the mountain. A transport trolley 1114 is used to transport heavy objects on the transport track. When transporting from the top of the mountain to the bottom of the mountain, a potential energy difference is generated. Therefore, the potential energy generated by the transport trolley 1114 carrying heavy objects when sliding from the top of the mountain to the bottom of the mountain can be collected and converted into electrical energy to provide power for the operation of the transport track. Specifically, the mountain top yard track 1111 is located at the top of the mountain, the mountain bottom yard track 1113 is located at the bottom of the mountain, and the power generation transport track 1112 is connected between the mountain top yard track 1111 and the mountain bottom yard track 1113. By providing a gravity potential energy generator 1115 on the power generation transport track 1112, the gravity potential energy generated by the transport trolley 1114 relative to the transport track is converted into electrical energy and directly transmitted to the power grid. Furthermore, the two cable car tracks form a cable car track group. During cargo transportation, the mountaintop yard track 1111, power generation transport track 1112, and mountain bottom transport track of each cable car track group are close to each other for easier management. Furthermore, one transport track in each cable car track group is connected to an unloading track 140 and to the same unloading area 150, thereby saving floor space, facilitating the unloading of heavy objects, and improving overall unloading efficiency. The unloading area 150 is used to unload the transport cart 1114 and then transport the heavy objects.

[0031] In one embodiment, each transport vehicle 1114 is spaced 60 meters apart and travels at a speed of 3 meters per second.

[0032] In one embodiment, the power generation and transport track 1112 is a linear track, facilitating the movement of the transport cart 1114 thereon. The ends of the uphill track 1112 are connected to the entrance of the mountaintop storage track 1111 and the exit of the mountainside storage track 1113, respectively. The ends of the downhill track 1112 are connected to the exit of the mountaintop storage track 1111 and the entrance of the mountainside storage track 1113, respectively, thereby forming a closed loop. Furthermore, the proximity of the uphill track 1112 and the downhill track 1112 facilitates the simultaneous installation of a gravitational potential energy generator 1115 on both the uphill track 1112 and the downhill track 1112.

[0033] In a specific embodiment, the substation 1116 is electrically connected to the transmission line of the power system. When the gravity potential energy generator 1115 transmits the generated electric energy to the substation 1116, the AC power can be converted into DC power through the side generator set and then the DC power can be redistributed to the power grid.

[0034] In a specific embodiment, there are more than two gravity potential energy generators 1115, which are arranged at intervals along the transport track from the mountain top yard track 1111 to the mountain bottom yard track 1113. Multiple gravity potential energy generators 1115 are arranged at equal intervals on the power generation transport track 1112, so as to avoid the transport cart 1114 generating excessive potential energy when sliding, exceeding the single gravity potential energy, causing part of the potential energy to be unable to be collected, resulting in waste of potential energy.

[0035] In a specific embodiment, the transport track is a circular closed loop, and the transport trolley 1114 can slide back and forth between the top of the mountain and the bottom of the mountain along a circular transport route.

[0036] In a specific embodiment, the bearing platform is a plate-shaped structure, which is symmetrically arranged with respect to the track center of the transport track, so that the bearing platform carrying heavy objects can smoothly deliver the heavy objects to the top or bottom of the mountain during transportation.

[0037] In a specific embodiment, the track of the mountain top yard track 1111 is "U"-shaped, and the entrance end and the exit end of the mountain top yard track 1111 are close to each other, and the track of the bottom mountain yard track 1113 is "U"-shaped, and the entrance end and the exit end of the bottom mountain yard track 1113 are close to each other, so that the uphill track 1112 and the downhill track 1112 of the power generation and transportation track 1112 are close to each other, which is convenient for the installation, inspection and maintenance of the track, and the adjacent uphill track 1112 and downhill track 1112 can reduce the floor space.

[0038] In one embodiment, the power generation and transport track 1112 is a linear track, facilitating the movement of the transport cart 1114 thereon. The ends of the uphill track 1112 are connected to the entrance of the mountaintop storage track 1111 and the exit of the mountainside storage track 1113, respectively. The ends of the downhill track 1112 are connected to the exit of the mountaintop storage track 1111 and the entrance of the mountainside storage track 1113, respectively, thereby forming a closed loop. Furthermore, the proximity of the uphill track 1112 and the downhill track 1112 facilitates the simultaneous installation of a gravitational potential energy generator 1115 on both the uphill track 1112 and the downhill track 1112.

[0039] According to the above embodiment, there are three cable car track groups, including a first cable car track group 110, a second cable car track group 120 and a third cable car track group 130. The first cable car track group 110, the second cable car track group 120 and the third cable car track group 130 are arranged side by side, and the lengths of the power generation and transportation pipelines of the first cable car track group 110, the second cable car track group 120 and the third cable car track group 130 gradually increase, and the lengths of the unloading tracks 140 of the first cable car track group 110, the second cable car track group 120 and the third cable car track group 130 gradually increase.

[0040] In this embodiment, the bottom yard track 1113 of the first cable car track group 110 is separated from the power generation and transportation track 1112 of the third cable car track group 130 by a preset distance, and the bottom yard track 1113 of the second cable car track group 120 is separated from the power generation and transportation track 1112 of the third cable car track group 130 by a preset distance, and the distance between the bottom yard track 1113 of the first cable car track group 110 and the power generation and transportation track 1112 of the third cable car track group 130 is greater than the distance between the bottom yard track 1113 of the second cable car track group 120 and the power generation and transportation track 1112 of the third cable car track group 130.

[0041] In one embodiment, the bottom yard tracks 1113 of adjacent cable car track groups are arranged side by side, and the bottom yard tracks 1113 of adjacent transport pipelines are arranged in a staggered manner, thereby avoiding the unloading area 150 located at a corner position.

[0042] In a specific embodiment, the two power generation transport pipelines of the cable car track group are close to each other, the two bottom-mountain yard tracks 1113 are close to each other, and the two top-mountain yard tracks 1111 are close to each other.
