Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage, and in particular relates to a mountain gravity energy storage system and method for continuously operating multiple blocks. Background Art

[0002] Because the total reserves of non-renewable energy such as oil and coal are decreasing worldwide, and their use will cause a series of environmental problems, finding new renewable clean alternative energy to control carbon emissions has gradually become a hot topic for countries around the world. As the proportion of new energy sources such as wind and light with intermittent and fluctuating characteristics continues to increase, the stability and safety and reliability of power system operation will face major challenges. In addition, the uncertainty and uncontrollability of power generation brought about by the high proportion of new energy access further increases the difficulty of peak and valley regulation of the power system, and leads to the phenomenon of wind and light abandonment in some local areas. Therefore, large-scale energy storage technology is of great significance to maintaining the stability of power systems with a high proportion of renewable energy.

[0003] Gravity energy storage technology has the advantages of large energy storage capacity, inherent safety of the system, and no limit on the number of charge and discharge times. It is a new energy storage technology with outstanding complementary advantages. In the existing technology, gravity energy storage based on mountains can usually be divided into slope track gravity energy storage and slope aerial cable car gravity energy storage. Slope track gravity energy storage requires the establishment of a complex transfer and stacking mechanism. The process is cumbersome and complicated, with large energy losses, and there are intervals during the replacement of heavy objects, which has the disadvantage of discontinuous power. Slope aerial cable car gravity energy storage technology uses overhead cables combined with electric and generators to suspend the heavy object carrier on the cable. The power is continuous and the operation is flexible, but it is difficult to achieve a larger energy storage capacity.

[0004] In addition, although the gravity energy storage system that relies on rails and cable cars to transport sand can avoid the shortcomings of the above two technologies to a certain extent and improve the system power and flexibility, its energy storage and power generation is limited by the volume of the sand storage. To achieve a larger energy storage capacity, it is necessary to build large-scale sand storage and other fixed facilities at the top and foot of the mountain, which has high construction costs and is difficult. Summary of the invention

[0005] In view of the above-mentioned deficiencies, the purpose of the present invention is to provide a mountain gravity energy storage system and method with multiple blocks in continuous operation, using standardized weight blocks as weight carriers, and utilizing the conversion between their gravitational potential energy and electrical energy to realize the charging and discharging of the energy storage system, and combining rail transportation and cable transportation methods to make the system input and output power continuous and flexibly adjustable, while increasing the carrying capacity of the weight carriers, improving the power and capacity of the energy storage system, and reducing costs.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: A mountain gravity energy storage system with multiple objects running continuously, comprising inclined rails, cableway brackets, load-carrying vehicles, standardized weight blocks, high-altitude automatic loading and unloading platforms, low-altitude automatic loading and unloading platforms, electric generator sets, transmission mechanisms and control systems; Inclined rails are laid on the slope of the mountain, connecting the high-altitude automatic loading and unloading platform and the low-altitude automatic loading and unloading platform, and guiding the truck forward. The inclined rails are laid continuously and the number is not less than two; The load-carrying vehicle is set on the inclined rails and is used to carry standardized heavy blocks. There are multiple load-carrying vehicles arranged at equal intervals; An overhead closed-loop cable is provided on the cableway support, and the cable is connected to the load vehicle buckle; The transmission mechanism and the electric generator set are connected to the cable to pull the load vehicle and control its up and down speed. At the same time, the cable can drive the electric generator set to generate electricity when the load vehicle is moving downward. The electric energy is finally transmitted to the power grid after being processed. The control system is used to control the operation of the high-altitude automatic loading and unloading platform, the low-altitude automatic loading and unloading platform, the transmission mechanism and the electric generator set.

[0007] A further improvement of the present invention is that the inclination angle of the mountain is greater than 0 degrees and less than 90 degrees.

[0008] A further improvement of the present invention is that the closed-loop cable is a steel cable or a synthetic fiber cable, which is connected to the cableway support through a fixed pulley block.

[0009] A further improvement of the present invention is that the truck is divided into a plurality of accommodating spaces at equal intervals by partitions along the track laying direction, each space can accommodate a standardized heavy object block, and at the same time, the truck is provided with automatically openable doors on both sides along the track laying direction, and the doors are connected to the control system signal.

[0010] A further improvement of the present invention is that steel wheels or rubber wheels matching the inclined rails are installed at the bottom of the truck, and a track electromagnetic brake for controlling the speed of the truck is provided.

[0011] A further improvement of the present invention is that the high-altitude automatic loading and unloading platform includes a high-altitude conveyor belt, a high-altitude heavy object storage platform and a high-altitude transfer device, and the low-altitude automatic loading and unloading platform includes a low-altitude conveyor belt, a low-altitude heavy object storage platform and a low-altitude transfer device. The high-altitude transfer device is used to transfer standardized heavy object blocks between the load-carrying vehicle and the high-altitude heavy object storage platform through the high-altitude conveyor belt, and the low-altitude transfer device is used to transfer standardized heavy object blocks between the load-carrying vehicle and the low-altitude transfer device through the low-altitude conveyor belt.

[0012] A further improvement of the present invention is that when the truck reaches the high-altitude automatic loading and unloading platform and the low-altitude automatic loading and unloading platform, the transmission mechanism controls the truck to slow down to about 0.5m / s, and then maintains a constant speed. The high-altitude conveyor belt and the low-altitude conveyor belt also maintain this constant speed.

[0013] A further improvement of the present invention is that the high-altitude transfer device and the low-altitude transfer device use telescopic fork devices, and the number of forks in each transfer device should be the same as the number of accommodating spaces in the load-carrying vehicle.

[0014] A further improvement of the present invention is that the high-altitude transfer device and the low-altitude transfer device are respectively installed on the high-altitude conveyor belt and the low-altitude conveyor belt, and run at the same speed as the high-altitude conveyor belt to complete the loading and unloading work of the truck.

[0015] A mountain gravity energy storage method with multiple objects running continuously, based on the mountain gravity energy storage system with multiple objects running continuously, comprises: In the energy storage state, an empty truck is loaded with standardized weight blocks at the bottom of the mountain through a low-altitude transfer device, and runs along the inclined rails to the top of the mountain under the control of an electric motor. The high-altitude automatic loading and unloading system transfers the standardized weight blocks to the high-altitude weight storage platform, and the above process is repeated to convert electrical energy into gravitational potential energy for storage; In the energy release state, the empty truck goes uphill under the control of an electric motor, and is loaded with standardized heavy blocks at the top of the mountain through a high-altitude transfer device. It then relies on its own gravity to run along the inclined rails to the bottom of the mountain. At the same time, the cable on it drives the generator to generate electricity, converting the mechanical energy of the truck's operation into electrical energy.

[0016] Compared with the prior art, the present invention has at least the following beneficial technical effects: The present invention provides a mountain gravity energy storage system and method with multiple blocks running continuously. The weight carrier adopts standardized weight blocks. The local tailings can be processed and recycled to make standardized weight blocks, which has certain social and economic value. At the same time, there is no need to build a large-scale sand warehouse and other fixed facilities, which reduces the cost and construction difficulty and reduces the impact on the environment. The present invention can provide continuous traction for the operation of the load-carrying vehicle by setting a closed-loop cable connected to the electric generator set. When releasing energy, the load-carrying vehicle continuously generates electricity through the cable traction generator, so that the input and output power of the system are continuous and flexibly adjustable. The present invention uses inclined rails to carry the weight of the weight carrier, which overcomes the shortcomings of large sag and limited carrying capacity when using overhead cables alone, so that a load-carrying vehicle can load multiple standardized weight blocks, greatly improving the power and capacity of the energy storage system. At the same time, the number of standardized blocks on the load-carrying vehicle can also be adjusted to change the gravitational potential energy, thereby improving the flexibility and safety of the system operation. By setting an automatic loading and unloading platform for heavy objects, the transfer and stacking mechanism is simplified, the energy loss during the loading and unloading of heavy objects is reduced, and the efficiency of the system energy cycle is further improved.

[0017] In summary, the system of the present invention is inherently safe, has no environmental pollution, and has no limit on the number of charge and discharge times. It has better environmental adaptability and higher operating efficiency than the pumped storage system. BRIEF DESCRIPTION OF THE DRAWINGS
