Description

Technical Field

[0001] This utility model belongs to the field of gravity energy storage technology, and in particular, it is a gravity block lowering guide device for gravity energy storage. Background Technology

[0002] Gravity energy storage is a technology that utilizes gravitational potential energy for energy storage and release. Its basic principle is to store the gravitational potential energy by lifting a heavy object (such as a gravity block) to a certain height; when energy needs to be released, the object falls, converting the potential energy into kinetic energy, which drives a generator to produce electricity. In a gravity energy storage system, the falling process of the gravity block is the key link in energy release. The gravity block converts gravitational potential energy into kinetic energy, thereby driving the generator to produce electricity. However, if the gravity block falls at too high a speed, it may cause excessive impact force, resulting in serious damage to equipment or the underground structure.

[0003] Existing gravity block lowering guidance devices typically lack effective speed control mechanisms, failing to adjust the gravity block's descent speed in a timely manner. This not only increases equipment wear but can also lead to deformation and breakage of the guide structure, and even safety accidents. Furthermore, the strong impact force can affect the stability of the gravity block, causing it to deviate from its intended trajectory, further exacerbating the risk of equipment failure. To address this issue, there is an urgent need for a new type of lowering guidance device that can effectively control the descent of the gravity block, provide a certain degree of protection, reduce impact force, and ensure the safe and reliable operation of the equipment.

[0004] The purpose of this invention is to provide a gravity block downhole guiding device for gravity energy storage, so as to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a gravity block downhole guiding device for gravity energy storage, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gravity block lowering guide device for gravity energy storage, comprising a gravity energy storage downhole frame, wherein guide grooves for guiding the lowering of gravity blocks are symmetrically opened in the downhole frame, and a placement box for supporting the gravity blocks is provided in the downhole frame, wherein a protective component for shock absorption and buffering is provided at the bottom of the placement box when it falls.

[0007] The protective component includes first mounting blocks symmetrically fixed on both sides of the placement box. A first connecting post is welded to the bottom of each first mounting block. A first spring is sleeved on the outside of the first connecting post. One end of the first spring is connected to the first mounting block, and the other end is connected to a mounting plate. A second connecting post is connected between the two mounting plates. A second spring is sleeved on the outside of the second connecting post.

[0008] Furthermore, the second connecting post is symmetrically slidably connected to a sliding block on its outer side, and the second spring is connected between the two sliding blocks.

[0009] Furthermore, a third mounting block is fixedly installed on the top of each sliding block, and one end of a rotating rod is rotatably connected inside the third mounting block.

[0010] Furthermore, the other end of the rotating rod is rotatably connected to a second mounting block, which is fixedly installed at the bottom of the placement box.

[0011] Furthermore, the placement box has a cavity for placing the gravity block, and a door is rotatably connected to the outside of the placement box, with a handle fixedly installed on the outside of the door.

[0012] Furthermore, the top of the placement box is provided with an iron cable for controlling the lifting and lowering of the placement box, and mounting frames are symmetrically fixedly installed on the top of the placement box. Each mounting frame is equipped with a guide wheel to reduce friction when the placement box falls.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention incorporates a protective assembly. After the placement box falls, a first spring provides initial cushioning protection, while a rotating rod rotates, pushing a sliding block to slide outside the second connecting column, compressing the second spring for a second cushioning protection. This effectively absorbs the impact force generated when the gravity block falls, reducing the risk of damage to the equipment and structure. By mitigating the impact on mechanical components, the protective assembly helps extend the equipment's lifespan, reduces maintenance and replacement costs, effectively prevents accidents, and ensures the safety of operators and equipment. Furthermore, the inclusion of guide grooves and guide wheels effectively reduces friction between the placement box and the downhole frame, increasing the falling speed of the gravity block and accelerating the conversion of gravitational potential energy into kinetic energy, thereby improving overall energy recovery efficiency. Reduced friction minimizes energy loss, ensuring more energy is effectively utilized, and reduces equipment instability during gravity block descent, lowering the risk of accidents or malfunctions.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] Please see Figures 1 to 4As shown, a gravity block lowering device for gravity energy storage includes a downhole frame 1 for gravity energy storage. The downhole frame 1 is existing equipment and will not be described in detail here. The downhole frame 1 has symmetrically arranged guide grooves 4 for guiding the lowering of gravity blocks. A placement box 3 for supporting the gravity blocks is provided inside the downhole frame 1. The placement box 3 has a cavity for placing the gravity blocks. A door 6 is rotatably connected to the outside of the placement box 3, and a handle 18 is fixedly installed on the outside of the door 6. Opening the door 6 allows the gravity blocks to be inserted into the placement box 3. It should be noted here that the gravity blocks... The size is adapted to the space inside the placement box 3, so that the gravity block will not swing around inside the placement box 3. The top of the placement box 3 is equipped with an iron cable 2 for controlling the lifting and lowering of the placement box 3. The iron cable 2 is used to connect and cooperate with the existing suspension machine. Both are devices well known to those skilled in the art, so the suspension machine is not shown here. The specific connection method and working principle are existing technologies and will not be described in detail here. The top of the placement box 3 is symmetrically fixed with mounting brackets 16. Each mounting bracket 16 is equipped with a guide wheel 5 to reduce friction when the placement box 3 falls.

[0027] The bottom of the placement box 3 is equipped with a protective assembly for shock absorption and cushioning when the placement box 3 falls. The protective assembly includes first mounting blocks 7 symmetrically fixed on both sides of the placement box 3. A first connecting post 8 is welded to the bottom of each first mounting block 7. A first spring 9 is sleeved on the outside of the first connecting post 8. One end of the first spring 9 is connected to the first mounting block 7. Upon impact, the first spring between the first mounting block 7 and the mounting plate 10 is compressed, thus providing initial shock absorption and cushioning protection. The other end is connected to the mounting plate 10. A second connecting post 17 is connected between the two mounting plates 10. A second spring 15 is sleeved on the outside of the second connecting post 17. When two sliding blocks 14 are pushed, the second spring between the two sliding blocks 14 is compressed, further... The second spring 15 provides a second shock absorption and buffer protection. Sliding blocks 14 are symmetrically slidably connected to the outside of the second connecting column 17. The second spring 15 is connected between the two sliding blocks 14. A third mounting block 13 is fixedly installed on the top of a single sliding block 14. One end of a rotating rod 12 is rotatably connected inside the third mounting block 13. The other end of the rotating rod 12 is rotatably connected to a second mounting block 11. The second mounting block 11 is fixedly installed at the bottom of the placement box 3. When the placement box 3 falls to the lowest point, after the mounting plate 10 contacts the ground, the first spring 9 performs the first buffer, and at the same time, the rotating rod 12 rotates, thereby compressing the second spring 15, thus providing the second buffer protection. Through the two buffer protections, the equipment is well protected and prevented from being damaged.

[0028] Working principle: Open the box door 6, fill the placement box 3 with the gravity block, and then lower the placement box 3 by the lifting cable 2 of the suspension machine. Then, the guide wheel 5 in the mounting frame 16 slides in the guide groove 4. When it falls to the lowest point, the mounting plate 10 contacts the ground, and the first spring 9 outside the first connecting column 8 in the first mounting block 7 is compressed, thus providing the first buffering effect. At the same time, the rotating rod 12 in the second mounting block 11 at the bottom of the placement box 3 rotates, which drives the sliding block 14 at the bottom of the third mounting block 13 to slide outside the second connecting column 17, thereby compressing the second spring 15 and providing the second buffering effect, thus protecting the placement box 3 and the gravity block.
