Description

Technical Field

[0001] The present invention relates to the technical field of electric energy storage, and in particular to an environmentally friendly large-mass gravity energy storage block for gravity energy storage. Background Art

[0002] The design of energy storage blocks is relatively rare nationwide. As one of the key structures for gravity energy storage, its structural form, force transmission mechanism, and construction method have not been fully designed and simulated. The stress conditions of the energy storage blocks are relatively complex, including the coordination between the upper and lower plates and the lateral squeezing force of the waste on the plates.

[0003] Existing tower-type concrete blocks are integrally formed and can be built directly on-site, making them more convenient, faster, and less expensive. However, the connection nodes are fragile and lack long-term durability. Underground shaft weight blocks need to be raised and lowered sequentially during operation, making continuous transportation impossible and inefficient. Weights are restricted by shaft size, wire rope strength, and power system power, limiting the weight and volume of a single transport and making it impossible to carry large loads. This type of weight block is expensive to manufacture, and the damp and dusty underground environment accelerates the aging of the weight blocks. Frequent inspection or replacement of components is required, resulting in high maintenance costs. Therefore, the present invention proposes an environmentally friendly, large-mass gravity energy storage block for gravity energy storage to address the problems existing in the prior art. Summary of the Invention

The environmentally friendly large-mass gravity energy storage block for gravity energy storage is connected by vertical steel plates and ear plates, and the force is generated by the lifting mechanism. The rigid force transmission system composed of transverse steel plates and through-steel bars can evenly transmit the lifting tension to the bottom exposed beam, forming a continuous force path, significantly improving the tensile strength and fatigue resistance, and constructing a spatial frame structure by supporting side columns and reinforced beams to effectively resist the lateral pressure of backfill material. By using solidified industrial waste as recycled backfill material, solid waste resource utilization is realized. At the same time, the concrete shell sealing effectively prevents heavy metal ions and pollutants, meeting environmental protection requirements.

DETAILED DESCRIPTION

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figure 1 、 Figure 2 、 Figure 3As shown, the present embodiment provides an environmentally friendly large-mass gravity energy storage block for gravity energy storage, comprising a concrete shell 1, a recycled backfill material 2, an anti-breaking mechanism, a lateral support mechanism and a bottom reinforcement mechanism. The concrete shell 1 is filled with recycled backfill material 2, chemical waste, industrial waste and other materials. The recycled backfill material 2 uses solidified industrial waste as filler, which not only provides gravitational potential energy but also realizes the resource utilization of solid waste. At the same time, the sealing design of the concrete shell 1 can prevent the precipitation of heavy metal ions and meet environmental protection requirements. The anti-breaking mechanism includes a top plate 3, an ear plate 4, a vertical steel plate 5, a horizontal steel plate 6, a through steel bar 7 and a lifting mechanism. The top cover of the concrete shell 1 is provided with a top plate 3, and the top plate 3 is arranged and fixed with ear plates 4. The lower end of the ear plate 4 passes through the top plate 3 and is symmetrically welded and fixed with a vertical steel plate 5. The bottom of the vertical steel plate 5 is matched with a horizontal steel plate 6 and is welded and fixed. The ear plate 4 is inserted into the concrete top plate 3 and welded to the vertical steel plate 5 without passing through the concrete top plate 3. After the bottom surface of 3 is flush, it is welded together with the horizontal steel plate 6. By welding the vertical steel plate 5 and the horizontal steel plate 6, the top plate 3 is formed and covered on the top of the concrete shell 1. The energy storage block is reinforced with steel bars inside the whole body to form a rigid connection with the concrete of the top plate 3 to evenly transmit the lifting tension to the concrete structure to avoid local stress concentration and cracking. The bottom of the horizontal steel plate 6 is arranged and welded with a through steel bar 7. The upper end of the through steel bar 7 is welded to the embedded part of the ear plate 4, and the lower end is welded and embedded in the bottom plate beam 17 to form a continuous force transmission path, which effectively prevents the problem of steel bars being pulled out or structural delamination during lifting operations. During installation, the vertical steel plate 5, the horizontal steel plate 6 and the through steel bar 7 are welded in sequence under the top plate 3. After welding, they will be placed in the concrete shell 1 and then the recycled backfill material 2 will be placed for filling to facilitate the control of the weight of the gravity energy storage block according to needs. A lifting mechanism is provided on the top plate 3, a lateral support mechanism is provided in the concrete shell 1, and a bottom reinforcement mechanism is provided at the bottom of the concrete shell 1.

[0020] The through steel bars 7 extend into the bottom of the concrete shell 1. There are multiple groups of through steel bars 7. The top plate 3 and the concrete shell 1 are sealed by pouring concrete, so that the concrete shell 1, the recycled backfill material 2 and the top plate 3 form a whole for easy lifting.

[0021] The lifting mechanism includes a connecting shaft 8, a fixed pulley 9 and a limit plate 10. The connecting shaft 8 is fixed between the ear plates 4, and the fixed pulley 9 is fixed on the connecting shaft 8. The limit plates 10 are arranged and fixed on the fixed pulley 9. The limit plates 10 are arranged at the same intervals. When lifting, the wire rope is passed around the fixed pulley 9 to convert the external lifting tension into a uniformly distributed vertical load to avoid concentrated stress causing cracks in the top plate 3.

[0022] The lateral support mechanism includes supporting side columns 11, side beams 12 and reinforcing beams 13. Supporting side columns 11 are provided on all four sides of the concrete shell 1. The supporting side columns 11 are located inside the side walls and form an integral body with the side walls. Side beams 12 are fixedly connected between the supporting side columns 11 along the transverse direction of the concrete shell 1. Reinforcing beams 13 are fixedly provided in the middle of the side beams 12. The supporting side columns 11 and the side beams 12 cooperate to form a frame inside the concrete shell 1. The reinforcing beams 13 pass through the interior of the concrete shell 1. A rigid space frame is formed by the supporting side columns 11 at the four corners and the transverse side beams 12, which effectively resists the static pressure generated by the internal recycled backfill material 2 and prevents the concrete side panels from bulging or cracking due to long-term lateral extrusion. The reinforcing beams 13 pass through the interior of the concrete shell 1 to evenly transfer the local concentrated load to the overall frame to avoid stress concentration.

[0023] The bottom reinforcement mechanism includes an energy storage block bottom plate 14, bottom plate steel bars 15, grooves 16 and exposed beams 17. The bottom of the concrete shell 1 is provided with an energy storage block bottom plate 14, and bottom plate steel bars 15 are provided between the energy storage block bottom plate 14 and the bottom of the concrete shell 1. Grooves 16 are arranged horizontally in the middle of the energy storage block bottom plate 14, and exposed beams 17 are arranged vertically and fixed on the energy storage block bottom plate 14. The lower end of the through steel bar 7 is embedded in the groove 16 and welded to the exposed beam 17. The lower end of the through steel bar 7 is embedded in the bottom plate groove 16 and welded to the exposed beam 17 to form a rigid connection, which converts the lifting tension into compression and shear force of the bottom plate to prevent the steel bar from being pulled out under dynamic load. The rigid connection between the exposed beam 17 and the through steel bar 7 reduces the vibration amplitude during the lifting operation and prevents fatigue cracks. Concrete is poured between the energy storage block bottom plate 14 and the bottom of the concrete shell 1 for fixed connection, and the concrete shell 1 is equipped with steel bars.

[0024] When in use, this environmentally friendly large-mass gravity energy storage block for gravity energy storage fills the recycled backfill into a sealed concrete shell, uses its gravitational potential energy to store energy, and converts the external lifting tension into a uniform vertical load through the fixed pulley on the top. The tension is transmitted to the bottom exposed beam through a rigid frame composed of ear plates, vertical steel plates and transverse steel plates and through-steel bars, and is converted into compression and shear force. The internal support frame composed of supporting side columns, side beams and reinforcement beams resists the lateral pressure of the backfill. The bottom reinforcement mechanism disperses the dynamic load through the rigid connection between the exposed beam and the through-steel bars, finally forming a complete force transmission chain from top lifting to bottom pressure, ensuring structural stability and environmental protection while realizing gravity energy storage.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments.
