[0030] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0031] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments.

[0035] like Figure 1-8 As shown, an embodiment of the present application provides a gravity energy storage block centrally placed buffer vibration suppression platform, which includes a weight placement platform 1, a first buffer portion 2, and a second buffer portion 3. The weight placement platform 1 has a concave card slot 11, which is recessed toward the inner side of the weight placement platform 1; the first buffer portion 2 is arranged on the side wall of the weight placement platform 1, one end of the first buffer portion 2 is connected to the side wall of the weight placement platform 1, and the other end is connected to the side wall adjacent to the weight placement platform 1; the second buffer portion 3 is arranged on the side of the weight placement platform 1 away from the concave card slot 11, one end of the second buffer portion 3 is connected to the weight placement platform 1, and the other end is in direct or indirect contact with the ground. The first buffer portion 2 and the second buffer portion 3 are configured to rely on their own expansion and contraction and damping effects to reduce the impact and vibration borne by the weight placement platform 1.
[0036] The gravity energy storage block in this embodiment is centrally placed on the buffer vibration suppression platform, which can improve the accuracy of placing the heavy object 6 through the concave slot 11. When placing the heavy object 6, the concave slot 11 and the protruding part of the heavy object cooperate to ensure that the heavy object 6 can accurately fall into the center position of the platform during the falling process, thereby ensuring the stability and reliability of the gravity energy storage device. In addition, the first buffer part 2 and the second buffer part 3 can effectively reduce the damage to the heavy object 6, the heavy object placement platform 1 and the various connecting components caused by impact and vibration, avoid problems such as component deformation and fatigue cracks caused by frequent and strong impacts, reduce the frequency of equipment maintenance and replacement, and thus extend the service life of the heavy object placement platform 1 and the entire gravity energy storage system related equipment.
[0037] like Figure 1-5As shown, in a specific embodiment, a third buffer portion is provided within the heavy object placement platform 1. The third buffer portion is provided within the heavy object placement platform 1 and is located at the bottom side of the concave slot 11. The third buffer portion is configured to reduce the impact and vibration experienced by the heavy object placement platform 1 by virtue of its own deformation when subjected to force. Specifically, the third buffer portion includes a buffer pad 4, the side walls of which are in contact with the inner wall of the heavy object placement platform 1, and the buffer pad 4 is made of EPDM rubber.
[0038] In this embodiment, the buffer plate 4 is installed below the internal concave slot 11 of the weight placement platform 1. The shape of the buffer plate 4 is consistent with the internal shape of the weight placement platform 1, ensuring that the buffer plate can be placed inside the weight placement platform 1, and the four sides of the buffer plate 4 are completely aligned with the four sides inside the weight placement platform 1, relying on the four sides and one bottom surface of the weight placement platform for positioning. In addition, the concave slot 11 is installed above the internal buffer plate 4 of the weight placement platform 1. The concave design of the concave slot 11 cooperates with the protruding portion of the weight 6 to ensure that the weight 6 can be accurately positioned when falling. The shape of the sidewalls of the concave slot 11 is consistent with the shape of the interior of the weight placement platform 1, ensuring that the size of the concave slot 11 can be placed inside the weight placement platform 1, and the four sides of the concave slot 11 are completely aligned with the four sides inside the weight placement platform 1, relying on the four sides inside the weight placement platform 1 and the upper surface of the buffer plate 4 for positioning.
[0039] like Figure 1-5 As shown, in a specific embodiment, there are multiple first buffer parts 2, and multiple first buffer parts 2 are arranged in pairs on the four side walls of the heavy object placement platform 1; the first buffer part 2 includes a first spring damper 21 and a first connecting member. The first connecting member includes a first fixed support 22 and a second fixed support 23; the two ends of the first spring damper 21 are respectively connected to the first fixed support 22 and the second fixed support 23 by a hexagonal bolt 24 and a hexagonal nut 25, the first fixed support 22 is connected to the side wall by an anchor bolt 26 and an anchor nut 27, and the second fixed support 23 is connected to the heavy object placement platform 1 by an ordinary bolt 28. When the heavy object 6 is placed on the heavy object placement platform 1, a lateral impact force will be generated, and the first buffer part 2 can effectively absorb and consume part of the energy, thereby reducing the impact on the entire system.
[0040] like Figure 1-5As shown, in one specific embodiment, the second buffering portion 3 includes a second spring damper 31. One end of the second spring damper 31 is threadedly connected to the bottom of the weight platform 1, and the other end is provided with a boss that contacts the ground. When a heavy object 6 is placed on the weight platform 1, it generates a significant impact. The second spring damper can withstand the pressure of the heavy object 6 and, through its own expansion and contraction and damping effects, reduce the impact force of the heavy object 6 on the ground and the weight platform 1.
[0041] In addition, the heavy object placement platform 1 includes a plurality of threaded holes, which are evenly distributed on the four sides of the heavy object placement platform 1. Each side includes 8 threaded holes. The 8 threaded holes are divided into two groups, each group of 4 threaded holes. They are connected by ordinary bolts 28 and the bottom threaded holes of the second fixed support 23 to ensure that the impact force and vibration of the heavy object placement platform 1 can be transmitted to the first spring damper 21. The bottom surface includes 4 threaded holes, which are evenly distributed on the bottom surface of the heavy object placement platform 1 to ensure the firmness and stability of the connection with the second spring damper 31.
[0042] When the weight 6 is placed on the platform 1, the first spring damper converts and consumes the lateral impact energy through spring expansion and damping when the weight 6 collides with the side wall. Simultaneously, the spring of the second spring damper absorbs the impact energy, and the damper dissipates the vibration energy, reducing the impact and vibration on the weight placement platform 1. Furthermore, the buffer plate 4 rapidly deforms and provides a buffer when the weight 6 contacts the concave slot 11, continuously absorbing and consuming vibration energy. These buffering devices work together to reduce impact vibration and protect the safe and stable operation of the weight 6, the platform, and the system.
[0043] like Figure 6 As shown, in a specific embodiment, the gravity energy storage block centrally placed buffer vibration suppression platform further includes a lifting device 5, which is used to lift and place the weight 6 on the weight placement platform 1. The concave card slot 11 is located at the top center of the weight placement platform 1, and the concave card slot 11 has the same shape as the protruding portion of the bottom of the weight 6. The gravity energy storage block centrally placed buffer vibration suppression platform needs to be installed directly below the lifting device 5 during installation to ensure that the weight 6 can be placed into the concave card slot 11 even if it is subjected to external disturbances or shakes during operation during placement on the platform.
[0044] Furthermore, current abandoned mine-type gravity energy storage uses steel wire ropes to lift heavy objects to store and release energy. When work is complete, the heavy objects need to be placed on a platform. During this process, the heavy objects impact the platform, and the intensity of this impact vibration and the platform's response behavior are difficult to monitor, making it difficult to accurately control the placement of the heavy objects. Traditional laser displacement sensors and accelerometers require external power to monitor the impact and vibration generated during the placement of the heavy objects on the platform. However, the heavy objects in gravity energy storage devices require long travel distances, posing a significant challenge to remote power supply for the sensors.
[0045] In this regard, Figure 1 and Figure 7-8 As shown, the gravity energy storage block centrally placed buffer vibration suppression platform in the embodiment of the present application also includes a vibration monitoring device 7, and the number of vibration monitoring devices 7 is multiple. The multiple vibration monitoring devices 7 are respectively arranged on the outer wall of the heavy object placement platform 1, and are configured to monitor the vibrations occurring in the X direction, Y direction and Z direction of the heavy object placement platform 1 respectively.
[0046] Specifically, multiple vibration monitoring devices 7 include an X-direction vibration self-monitoring device, a Y-direction vibration self-monitoring device, and a Z-direction vibration self-monitoring device, which are respectively installed on three sides of the heavy object placement platform 1, among which the X-direction vibration self-monitoring device and the Y-direction vibration self-monitoring device are horizontally installed on two adjacent sides of the heavy object placement platform 1, and the Z-direction vibration self-monitoring device is vertically installed on the other side of the heavy object placement platform 1.
[0047] like Figure 7-8 As shown, in a specific embodiment, the vibration monitoring device 7 includes a clamp 71, a concentrated mass 72, an elastic cantilever beam 73, a piezoelectric film 74, a signal collection device 75, a data acquisition instrument 76, and a PC terminal 77; the clamp 71 clamps one end of the elastic cantilever beam 73, the piezoelectric film 74 is attached to the side wall of the elastic cantilever beam 73, and the concentrated mass 72 is fixed to the other end of the elastic cantilever beam 73. The vibration monitoring device 7 can accurately monitor the impact and vibration generated by the heavy object 6 when it is placed on the heavy object placement platform 1 in real time. The vibration in the X, Y, and Z directions is monitored from different dimensions by the self-monitoring device 7. The elastic cantilever beam 73 is deformed by vibration, and the piezoelectric film 74 converts it into an electrical signal, thereby grasping the vibration parameters in each direction. This function can detect abnormal impact vibration in a timely manner, control the impact behavior of the heavy object through system feedback, and avoid damage to the heavy object and related components.
[0048] When a heavy object is placed on the heavy object placement platform 1, the vibration and impact generated drive the clamp 71 to vibrate, thereby causing the elastic cantilever beam 73 to deform, triggering the piezoelectric film 74 to generate an electrical signal. On the one hand, the electrical signal is transmitted to the data acquisition instrument 76, and after being collected and processed by the data acquisition instrument 76, it is displayed on the PC terminal 77 to monitor the vibration impact data generated. On the other hand, these electrical signals provide power support for low-power equipment or auxiliary systems, reduce dependence on external power supplies, and reduce the operating cost of the system. The vibration monitoring device 7 realizes the conversion of vibration energy and electrical energy through the deformation of the piezoelectric film 74 on the elastic cantilever beam 73 under the impact vibration of the platform. By collecting the electrical signals, the energy utilization efficiency of the entire gravity energy storage system is improved.
[0049] like Figure 7 As shown, in a specific embodiment, the clamp 71 includes a screw 711, a base 712, a guide rail 713, a movable jaw 714, a locking bolt 715, a guide rail fixing seat 716 and a fixed jaw 717; the base 712 is connected to the heavy object placement platform by bolts, the guide rail 713 fixing seat and the guide rail 713 are set on the base 712, the fixed jaw 717 and the movable jaw 714 are arranged opposite to each other, and the fixed jaw 717 is fixed relative to the base 712, the movable jaw 714 is slidably connected to the guide rail 713, the screw 711 is threadedly connected to the movable jaw 714 and can drive the movable jaw 714 close to or away from the fixed jaw 717, and the locking bolt 715 can relatively fix the movable jaw 714 and the screw 711.
[0050] Specifically, the guide rail 713 is connected to the guide rail 713 fixed seat by bolts, the screw 711 is connected to the base 712 by bearings, the movable jaw 714 is connected to the screw 711 by threads, the fixed jaw 717 is connected to the base 712 by bolts, the locking bolt 715 is connected to the movable jaw 714 by threads, the base 712 is connected to the heavy object placement platform by bolts, the movable jaw 714 is adjusted in position by the screw 711 to clamp the elastic cantilever beam, and the locking bolt 715 is used to fix the position of the movable jaw 714.
[0051] The working principle of the gravity energy storage block centering buffer vibration suppression platform in the embodiment of the present application is as follows: when the weight 6 is placed on the weight placement platform 1, the protruding portion of the weight 6 first contacts the groove portion of the concave groove 11. The side of the protruding portion of the weight 6 falls closely along the groove shape of the concave groove 11. The groove shape design of the concave groove 11 ensures that the weight 6 can fall along the predetermined path, preventing the weight 6 from deflecting and shaking during the fall. At the moment when the weight 6 contacts the concave groove 11, impact and vibration are generated. The buffer plate 4 quickly deforms, absorbing and buffering the vibration energy, and transferring the excess impact force and vibration to the weight placement platform 1. At this time, the second spring damper 31 quickly compresses, absorbing the vertical impact force on the weight placement platform 1, gradually dissipating the impact energy, thereby reducing the impact of the weight 6 on the ground and the weight placement platform 1. The first spring damper 21 comes into play when the weight 6 is laterally displaced or subjected to lateral force during the process of being placed on the weight placement platform 1. Through the expansion and contraction and damping effect of the spring, the lateral impact energy is effectively absorbed and consumed, thereby preventing the heavy object placement platform 1 from violently colliding with the side wall and reducing the impact of the lateral impact force on the entire system.
[0052] To address the difficulty in monitoring the impact intensity and platform response behavior generated by the heavy object 6 when it is placed on the heavy object placement platform 1, the vibration monitoring device 7 can monitor the X, Y, and Z directions. The impact vibration generated by the heavy object 6 when it is placed on the heavy object placement platform 1 causes the elastic cantilever beam 73 to deform due to the vibration, and the piezoelectric film 74 converts this into an electrical signal. The collected electrical signals are collected and processed by the data acquisition device 76 and then displayed on the PC terminal 77 for monitoring the generated vibration and impact data. Furthermore, these electrical signals provide power support for low-power devices or auxiliary systems, reducing dependence on external power supplies and lowering the system's operating costs.
[0053] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
