Description

Technical Field

[0001] This invention relates to the field of new energy technology, and more specifically, to a slope-type gravity energy storage and power generation system based on multi-vehicle vertical circulation automatic loading and unloading. Background Technology

[0002] With the rapid development of industrial production, electricity demand continues to grow, and the difference between peak and off-peak loads on the power grid is widening, making the peak-shaving pressure on the power system increasingly prominent. To solve this problem, the development of efficient and reliable energy storage technologies is particularly important. Currently, the mainstream energy storage technologies include three main categories: physical energy storage, chemical energy storage, and electromagnetic energy storage, each with its own characteristics and limitations.

[0003] The development of gravity energy storage technology still faces multiple challenges. In the field of gravity energy storage, vertical shaft energy storage methods relying on abandoned mines are not only limited by specific terrain but also require complex structural design requirements, while their energy storage efficiency is relatively low. Gravity energy storage systems based on mountainsides, although seemingly simple in their components, primarily rely on cable traction, chain drive, and self-powered trolleys for transmission, which suffers from transmission instability and struggles to meet the needs of practical applications.

[0004] Existing inclined gravity energy storage systems, during cyclic transportation, require the trolley track to function as both an upward and downward track, simultaneously meeting the load-bearing requirements of both empty and heavily loaded trolleys. This results in high track infrastructure requirements, high costs, and a large footprint. When loading and unloading heavy objects, existing inclined gravity energy storage systems typically use lifting devices to separate the heavy objects from the trolley, increasing system energy consumption and complexity, and reducing the cyclic efficiency of the gravity energy storage system. Furthermore, existing inclined gravity energy storage systems mix the transport and loading / unloading areas, lacking a buffer zone design between them. This causes mutual interference between trolley transfer and heavy object loading / unloading operations, resulting in waiting times and preventing continuous, uninterrupted system operation, thus reducing the efficiency of the gravity energy storage system. Chinese patent "Inclined Gravity Energy Storage System and Energy Storage and Power Generation Method Based on Multi-Trolley Circulation Chain," publication number (CN120120208A), addresses the problems of high load-bearing requirements, large footprint, and high infrastructure costs associated with trolley track infrastructure during cyclic transportation.

[0014] The inclined gravity energy storage and power generation system based on multi-vehicle vertical circulation automatic loading and unloading, which implements the present invention, has the following beneficial effects: 1. This invention addresses the problem that the energy storage system (conveyor chain) needs to be shut down during the loading and unloading process of a mobile trolley. By separating the loading and unloading area from the energy storage system, the mobile trolley can load / separate heavy objects without requiring the energy storage system (conveyor chain) to be shut down. At the same time, a conveyor belt separation device is designed so that the heavy objects move horizontally along the conveyor belt and the trolley moves downward along the track, thus separating the heavy objects from the trolley. This realizes the cyclic operation of the system and improves the loading and unloading efficiency. 2. To address the problem of inefficiency in transporting heavy objects with a single track and a single trolley, this invention adopts a vertical arrangement of upper and lower double tracks, with multiple trolleys on each track transporting heavy objects simultaneously. Furthermore, the energy of the trolley going downhill on the upper track can be recovered and used by the trolley going uphill on the lower track for climbing. 3. The present invention adopts a vertical arrangement of upper and lower double tracks. During the energy storage and discharge stages, the loaded trolley runs on the lower track and the unloaded trolley runs on the upper track, which reduces the load-bearing requirements of the upper track and reduces construction difficulty and cost. 4. This invention designs an automatic separation device between the trolley and the heavy object, allowing the heavy object to move horizontally along the conveyor belt while the trolley moves downwards along the track, achieving automatic separation between the heavy object and the trolley, and vice versa, thus improving loading and unloading efficiency. This device can replace the lifting and separation device, reducing the operating energy consumption of the gravity energy storage system. Attached Figure Description

[0016] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1-7 As shown, the slope-type gravity energy storage power generation system based on multi-vehicle vertical circulation automatic loading and unloading of the present invention includes an upper storage yard 1 and a lower storage yard 2. The upper storage yard 1 is located on a mountain, and the lower storage yard 2 is located at the foot of the mountain. A mountain slope 8 connects the upper storage yard 1 and the lower storage yard 2. Heavy blocks 7 are stacked on both the upper storage yard 1 and the lower storage yard 2. An upper crane 5 is mounted on the upper storage yard 1 and is located above the heavy blocks 7. A lower crane 6 is mounted on the lower storage yard 2 and is located above the heavy blocks 7. A rail conveying device is provided between the upper crane 5 and the lower crane 6. Both the upper crane 5 and the lower crane 6 are gantry cranes. The rail conveying device includes a rail, which comprises a transport rail and a loop rail. The transport rail is located on the mountain slope 8 and includes an upper transport rail 3 and a lower transport rail 4. The upper transport rail 3 is positioned above the lower transport rail 4. The loop rail includes an upper loop rail 11 and a lower loop rail 22. The upper loop rail 11 is located in the upper storage yard 1 and connects to the top of the transport rail, while the lower loop rail 22 is located in the lower storage yard 2 and connects to the bottom of the transport rail. A conveyor belt 9 and a transmission belt 10 are installed on the loop rail 11, with the transmission belt 10 positioned above the transmission belt 9. The transmission belt 9 covers the entire length of the loop rail and is used to drive the trolley 13 back after it disengages from the conveyor chain 15. The transmission belt 10 is located at the junction of the loop rail and the transport rail, and includes two sections located on the sides of the upper crane 5 and the lower crane 6, respectively. The conveyor belt 10 is used to transport the heavy block 7 to the upper part of the trolley 13. The conveyor belt 10 has an open structure in the middle and is mounted above the loop track 11.

[0018] Multiple trolleys 13 for loading heavy blocks 7 are connected to the track. The trolleys 13 move along the track. Conveyor chains 15 are provided on both sides of the transport track, and side hooks 16 are provided on both sides of the trolleys 13. The trolleys 13 are engaged with the conveyor chains 15 by the side hooks 16, enabling the trolleys 13 to move up and down on the transport track. A generator 12 for energy storage is provided on the upper side of the transport track. The generator 12 is connected to a support sprocket 14 through a rotating shaft, and the conveyor chains 15 are mounted on the support sprocket 14. There are two generators 12, located on the left and right sides of the upper end of the transport track, respectively.

[0019] In a preferred embodiment of the present invention, the aim is to help power plants balance power generation and power consumption. When power generation exceeds power consumption, a heavy block 7 is loaded from the lower loading and unloading area 17 onto a trolley 13, transported from the second position 18 to the first position 20 via the conveying area 19, and then unloaded from the upper loading and unloading area 21 to the upper storage yard 1, thus realizing the process of transporting the heavy block 7 from the lower storage yard 2 to the upper storage yard 1, converting the excess electricity into gravitational potential energy for storage. When power generation is less than power consumption, the heavy block 7 is loaded from the upper loading and unloading area 21 onto a trolley 13, transported from the first position 20 to the second position 18 via the conveying area 19, and then unloaded from the lower loading and unloading area 17 to the lower storage yard 2, thus realizing the process of transporting the heavy block 7 from the upper storage yard 1 to the lower storage yard 2. During the transport process, the heavy block drives the electric generator 12 sets to generate electricity, converting gravitational potential energy into electrical energy.

[0020] In a preferred embodiment of the present invention, during the energy storage and discharge phases of the system, the loaded trolley 13 runs on the lower track, while the unloaded trolley 13 runs on the upper track. The driving direction of the generator 12 is opposite during the transition between the two phases. Therefore, during the energy storage phase, the generator 12 drives the conveyor chain 15 to rotate via the support sprocket 14, thereby causing the loaded trolley 13 to move upwards on the lower track and the unloaded trolley 13 to move downwards on the upper track, thus converting excess electrical energy into gravitational potential energy for storage. During the discharge phase, the loaded trolley 13 moves downwards on the lower track and the unloaded trolley 13 moves upwards on the upper track, driving the electric generator 12 to generate electricity, converting gravitational potential energy into electrical energy.

[0021] In a preferred embodiment of the present invention, the energy storage process of the system is as follows: the trolley 13 enters the second position 18, the side hook 16 of the trolley 13 disengages from the conveyor chain 15, the trolley 13 contacts the conveyor belt 9, and the trolley 13 enters the lower loading and unloading area 17 under the drive of the conveyor belt 9. The lower crane 6 lifts the heavy block 7 onto the conveyor belt 10. The trolley 13 is located in the lower loading and unloading area 17, and the speeds of the conveyor belt 9 and the conveyor belt 10 are consistent. As the trolley 13 moves along the track, the heavy block 7 is automatically loaded onto the trolley 13 along the conveyor belt 10. The trolley 13 disengages from the conveyor belt 9, and the side hook 16 of the trolley 13 engages with the conveyor chain 15. The generator 12 of the upper storage yard 1 drives the support sprocket 14 to drive the conveyor chain 15, thereby pushing the trolley. As the trolley 13 and the heavy block 7 move, the conveyor chain 15 drives the trolley 13 to move along the lower track from the lower storage yard 2 to the upper storage yard 1. The trolley 13 enters the first position 20, and the side hook 16 of the trolley 13 disengages from the conveyor chain 15. The trolley 13 contacts the conveyor belt 9, and the conveyor belt 9 drives the trolley 13 into the upper loading and unloading area 21. The conveyor belt 10 maintains the same speed as the conveyor belt 9. During the trolley 13's descent, the heavy block is automatically separated from the trolley 13. The upper crane 5 moves the heavy block 7 away from the conveyor belt 10. The trolley 13 leaves the upper loading and unloading area 21 under the drive of the conveyor belt 9. The trolley 13 disengages from the conveyor belt 9, and the side hook 16 of the trolley 13 engages with the conveyor chain 15, running along the upper track to the second position 18.

[0022] In a preferred embodiment of the present invention, a pressure sensor monitors the pressure on the conveyor belt, and a speed monitor monitors the speed of the trolley 13. Data is collected, and the system analyzes and processes the pressure of the heavy block 7 and the speed of the trolley 13 to determine whether the power of the gravity energy storage system meets and remains stable. If the demand is met and stability is maintained, the existing speed and spacing of the trolley 13 are maintained to ensure the stability of the power generation / storage, and the monitoring data is updated in real time. If the demand is not met or power fluctuations occur, the existing speed and spacing of the trolley 13 are adjusted, triggering the operation of the 12 sets of electric generators to dynamically adjust the power generation / storage according to demand until the power generation / storage stabilizes and reaches the required value. This control system achieves cyclical operation, improving loading and unloading efficiency.
