Description

Technical Field

[0001] The present invention relates to the technical field of gravity energy storage, and particularly to a special steel structure module for gravity energy storage. Background Art

[0002] Gravity energy storage technology is a new type of energy storage technology. Due to its advantages such as low cost per kilowatt-hour and flexible site selection, it has gradually received attention in the energy storage technology field and has been applied to a certain extent. Existing gravity energy storage technologies can be divided into suspension type, new pumped-storage type, and inclined type.

[0003] For example, Chinese Patent CN114704445A discloses a gravity energy storage module and a modular gravity energy storage system, which includes multiple layers of mass block layers, elevator devices on both sides, and a generator. The multiple layers of mass block layers are stacked vertically, and each layer of mass block layer is provided with multiple mass block storage positions horizontally. A horizontal trolley for horizontally transporting the mass blocks is provided under each layer of mass block layer. The elevator devices on both sides are arranged on both sides of the multiple layers of mass layers to transport the mass blocks up and down, and the elevator devices are connected to the generator to drive the generator to generate electricity. Each layer of mass block layer includes a frame structure, trolley tracks, and mass block bearing beams. Two trolley tracks are arranged in parallel on the frame structure. The overall width of the frame of the horizontal trolley is greater than the distance between the two trolley tracks, which can effectively prevent the trolley from falling. There is no need to separate the mass block layers between the upper and lower layers by a bottom plate, but the spatial separation can be achieved through this vertical main beam and cross beam structure. The overall frame structure, trolley tracks, and mass block bearing beams are constructed by a reinforced concrete structure combining prefabricated parts and in-situ casting, with a simple and compact structure and high building strength.

[0004] Chinese Patent CN111692055A discloses a gravity energy storage system and its usage method. The gravity energy storage system includes: mass blocks; a load-bearing structure, the load-bearing structure includes fixing parts and load-bearing walls, multiple load-bearing walls are arranged in parallel at intervals, a lifting channel is formed between two adjacent load-bearing walls, the fixing parts are connected to the load-bearing walls and are located in the lifting channel, and the fixing parts are used to carry the mass blocks; a lifting structure, the lifting structure includes a gantry crane, and the motor equipment in the gantry crane is set as a generating motor. The gantry crane is installed at the top of the load-bearing wall, and the gantry crane is used to carry the mass blocks. With the above structure, the gravity energy storage system has lower requirements for geographical conditions and smaller floor area.

[0005] Chinese Patent CN115450870A discloses a frame structure for gravity energy storage and its gravity energy storage system. The storage layer frame includes a storage area frame and a storage layer lifting channel frame installed and connected to the auxiliary lifting unit frame. The storage area frame includes a number of storage layer columns arranged in an array in the Z direction. Each storage layer column is spacedly installed with a number of mounting brackets for installing transfer device guide rails and gravity block support beams in the Z direction, so as to form a plurality of X-direction storage layer channels and / or a plurality of Y-direction storage layer channels. The transfer device guide rails extend through the corresponding X-direction storage layer channels and Y-direction storage layer channels; the space between every four adjacent mounting brackets forms a gravity block storage area unit for accommodating gravity blocks. The transfer device guide rails are relatively displaceably installed with a transfer device and extend to the storage layer lifting channel frame for converting the transfer direction of the gravity blocks; the overall frame structure has few joints, simple technology, easy control of the overall dimensions and maintenance, and a long service life.

[0006] Chinese Patent CN115772944A discloses a building structure based on gravity energy storage, which is composed of an external cylinder and an internal frame. The external cylinder includes: horizontal shear walls, vertical shear walls, external frame concrete columns, and external frame concrete beams. The horizontal shear walls are fixedly connected to the vertical shear walls at equal intervals. The external frame concrete columns and external frame concrete beams are arranged between the horizontal shear walls and the vertical shear walls; the internal frame includes: concrete-filled steel tube columns and concrete beams, and the concrete-filled steel tube columns and concrete beams are arranged inside the external cylinder. The present invention adopts a giant frame structure composed of an internal frame and an external cylinder, which is convenient for construction and installation, has a simple form, and can meet the process requirements of gravity energy storage devices.

[0007] Chinese Patent CN218667942U discloses a precast track beam joint based on gravity energy storage, including: a beam-beam splicing joint and a beam-column connection joint. The beam-beam splicing joint is located at the connection of the precast track beams, and the beam-column connection joint is located at the connection of the frame columns and the precast track beams in the column grid of the gravity energy storage structure. Its precast track beam joint based on gravity energy storage has a simple structure, with a beam-beam splicing joint and a beam-column connection joint. Among them, the beam-beam splicing joint realizes the connection of the horizontal precast track beams, and the beam-column connection joint realizes the connection of the frame columns and the precast track beams. There are few fittings at the joints, which is convenient for assembly. At the same time, it also greatly shortens the on-site construction hoisting time, saving a large amount of labor and construction period.

[0008] As can be seen from the above description, existing gravity energy storage structures often adopt concrete structures. The construction period of using cast-in-place concrete structures is long, there are many on-site wet operations, and it is difficult to ensure the accuracy requirements for the operation of equipment in gravity energy storage. Adopting precast concrete structures can ensure the processing accuracy of components, but the force-bearing components adopt sleeve connection methods, and the connection quality is difficult to detect, and the integrity of the main structure cannot be guaranteed. Summary of the Invention

[0009] The object of the present invention is to design a special steel structure module for gravity energy storage. By adopting a modular structure, standardized processing is realized, which improves the processing accuracy and efficiency, and also greatly improves the on-site construction efficiency. At the same time, the stability of the gravity energy storage structure is improved to ensure the normal operation of gravity energy storage operations.

Through the above design, the stability of the gravity energy storage structure is improved, ensuring the normal operation of the gravity energy storage operation.

Under the action of rare earthquakes, when all the weight blocks are arranged at the top of the structure, the maximum inter-story displacement angle of the structure is less than 1 / 50, meeting the inter-story deformation requirement.
