Description

Spiral tower gravity energy storage Technical Field

[0001] The present invention relates to the technical field of energy storage and gravitational potential energy application, in particular to a spiral tower type gravity energy storage device. Background Art

[0002] Currently, various energy storage systems have been developed that require lifting heavy objects to a certain height so that the energy can be released when demand is high.

[0003] For example, some systems utilize the lifting of carriages to store gravitational potential energy. These systems require large areas and sloping terrain, and utilize concrete blocks to develop energy storage systems. These systems operate like a set of elevators, raising concrete blocks when energy is in excess and lowering them when energy is needed. However, these systems have capacity limitations, as each block requires a separate elevator. Summary of the Invention

[0004] The present invention aims to provide a spiral tower gravity energy accumulator to solve the problem of raising concrete blocks when there is excess energy and lowering them when there is energy demand, as proposed in the background art. This system has limitations in capacity because each weight block requires a separate elevator.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a spiral tower gravity energy storage device, comprising:

[0006] Upper parking lot, lower parking lot, spiral tower, crane;

[0007] The upper parking lot is located directly above the lower parking lot, and the upper parking lot and the lower parking lot are supported by a structure;

[0008] The spiral tower and the crane are arranged on the left and right sides of the upper parking lot and the lower parking lot. The generator carriage on the spiral tower is parked on the spiral tower, and the lower side of the crane's lifting rope is connected to the lifted generator carriage.

[0009] Preferably, the structure is column-shaped and is arranged at the four corners between the upper parking lot and the lower parking lot.

[0010] Preferably, a generator car track 1 is provided on the right side of the upper parking lot, a spiral tower entrance is provided on the right side of the generator car track 1, and the spiral tower entrance corresponds to the upper side of the spiral tower.

[0011] Preferably, a generator car track 2 is provided on the right side of the lower parking lot, a spiral tower exit is provided on the right side of the generator car track 2, and the spiral tower exit corresponds to the lower side of the spiral tower.

[0012] Preferably, the generator carriage track 1 and the generator carriage track 2 are gathered from left to right.

[0013] Preferably, the upper surfaces of the upper parking lot and the lower parking lot are both provided with transverse movement tracks.

[0014] Preferably, at least one crane is provided. When multiple cranes are provided, the cranes are connected via a crane travel lane.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] It offers significant advantages in terms of space, capacity, and operational efficiency. It stores energy (gravitational potential energy) at high altitudes when demand is low, allowing it to be released when demand is high. The spiral tower structure increases the descent time of the carriages and allows for simultaneous descents. It offers large storage capacity in a small space, making it suitable for a variety of renewable or other energy sources. Compared to systems that require a crane for each generator carriage, a single crane can lift multiple carriages, improving crane utilization. It occupies a small footprint and is mostly metal, allowing it to be completely disassembled and recycled. Its durability can last for decades. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] Please refer to Figures 1-4. The present invention provides a technical solution: a spiral tower gravity energy storage device, characterized by comprising: an upper parking lot 1, a lower parking lot 4, a spiral tower 3, and a crane 6;

[0026] Among them, the upper parking lot 1 is located directly above the lower parking lot 4, and the upper parking lot 1 and the lower parking lot 4 are supported by a structure 7. The spiral tower 3 and the crane 6 are arranged on the left and right sides of the upper parking lot 1 and the lower parking lot 4. The generator car 2 on the spiral tower is parked on the spiral tower 3, and the lower side of the lifting rope of the crane 6 is connected to the lifted generator car 5.

[0027] The structure 7 is column-shaped and is arranged at the four corners between the upper parking lot 1 and the lower parking lot 4. A generator car track 1 7 is provided on the right side of the upper parking lot 1, and a spiral tower entrance 8 is provided on the right side of the generator car track 1 7. The spiral tower entrance 8 corresponds to the upper side of the spiral tower 3. A generator car track 2 10 is provided on the right side of the lower parking lot 4, and a spiral tower exit 11 is provided on the right side of the generator car track 2 10. The spiral tower exit 11 corresponds to the lower side of the spiral tower 3. The generator car track 1 7 and the generator car track 2 10 are gathered from left to right. The upper surfaces of the upper parking lot 1 and the lower parking lot 4 are both provided with lateral movable tracks.

[0028] At least one crane 6 is provided. When multiple cranes 6 are provided, the cranes 6 are connected via a crane travel lane 9 .

[0029] The generator carriage 2 on the spiral tower and the suspended generator carriage 5 refer to the same type of generator carriage, but are located in different positions.

[0030] One or more cranes 6 lift the generator car to upper parking lot 1, where it is stored until needed. Upper parking lot 1 and lower parking lot 4 are connected. When crane 6 places generator car 2 and the hoisted generator car 5 on the spiral tower onto the tracks, gravity moves them into position. When energy / electricity is needed, generator car 2 and the hoisted generator car 5 on the spiral tower descend along the tracks onto spiral tower 3.

[0031] After the generator cars 2 are lowered from the spiral tower, they are neatly stored in the lower parking lot 4, where they await energy surplus. A crane 6 then moves the hoisted generator cars 5 to the upper parking lot. This lower parking lot 4 is slightly inclined, allowing the cars to be moved into position under the influence of gravity.

[0032] Parking space: The system has at least two parking spaces, one above and one below (there can be more parking spaces in the middle to expand the space for storing compartments).

[0033] The lower parking lot 4 has a slight slope so that when the generator car 2 on the spiral tower reaches the bottom of the spiral tower 3, it can be orderly moved to its position on the lateral movement tracks through multiple lateral movement tracks until it is hoisted again. The lower parking lot 4 also has one or more cranes 6. When there is excess energy, the cranes 6 can lift the hoisted generator car 5 to the upper parking lot 1.

[0034] The upper parking lot 1 is a structure consisting of multiple tracks on which the carriages can travel. The parking lot is slightly inclined so that the carriages will move toward the spiral tower and enter the entrance via the tracks (there will be a control system so that the carriages enter in an orderly manner and when they are needed).

[0035] Crane 6: The system may be equipped with one or more cranes 6 to lift the hoisted generator carriage 5 to the upper parking lot 1.

[0036] The generator carriage 2 on the spiral tower and the suspended generator carriage 5 are devices that run on rails or tracks and can adjust their speed (set). These carriages carry a generator (which can be any existing or future generator) and release the stored energy to the grid when descending.

[0037] Spiral Tower 3: The generator car descends through Spiral Tower 3.

[0038] Frame 7: The system is supported by a frame which can be made of metal, concrete or any other material capable of supporting the components.

[0039] The system would be installed near power generation equipment (such as wind or solar / photovoltaic farms). During periods of high power generation and low power demand, this excess power would be transferred to the storage system.

[0040] At this point, the system will continue to use crane 6 to utilize the excess energy to lift the carriages to higher floors (the more energy there is left, the more carriages can be lifted, and the higher the parking lot for storing the carriages).

[0041] When energy demand exceeds production (or production is insufficient to meet grid demand), the generator cars located on the upper parking lot 1 begin to release and descend from the spiral tower 3. During the descent, the generator cars generate energy (due to the potential energy generated by gravity, the energy used during the ascent is the same as the energy generated during the descent, thus acting as energy storage) until they reach the lower parking lot 4. The energy generated during the descent will be fed into the grid or used for whatever purpose you desire through this system.

[0042] When the generator car arrives at the lower parking lot 4, the generator car travels along the rails or the road and is repositioned in the parking lot. When necessary, the car moves upwards again.

[0043] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure signs in the claims should not be regarded as limiting the claims involved.
