Description

Technical Field

[0001] This utility model relates to a gravity block guiding fixture for a gravity compressed air energy storage system, belonging to the field of gravity compressed air energy storage technology. Background Technology

[0002] Gravity compressed air energy storage cleverly combines the advantages of gravity energy storage and conventional compressed air energy storage, avoiding their respective disadvantages. It can meet our requirements for energy storage systems with large capacity, low cost, long lifespan, high efficiency, strong safety, fast adjustment speed, minimal environmental impact, and flexible deployment. In existing technologies, traditional compressed air energy storage systems lack gravity block guiding fixtures, resulting in unstable gravity block strokes and system damage in case of loss of control. To address these issues, we propose a gravity block guiding fixture for gravity compressed air energy storage systems. Utility Model Content

[0003] The purpose of this utility model is to provide a gravity block guide fixture for a gravity compressed air energy storage system, which makes the gravity block support firm and the stroke stable, solving the problem of unstable gravity block stroke in traditional compressed air energy storage systems. At the same time, it can detect the running speed of the gravity block and play a protective role in conjunction with a speed limiter and safety clamp.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a gravity block guiding fixture for a gravity compressed air energy storage system, including a vertical shaft, in which a gravity block is inserted, and a sealing part is provided between the bottom side wall of the gravity block and the inner wall of the vertical shaft. It also includes a gantry frame spanning above the vertical shaft, the gantry frame being erected on the ground, its bottom reinforced by a steel-concrete structure, and reinforced ribs on both sides to improve its stability. Slide rails are vertically installed on the inner sides of both ends of the gantry frame. The top sides of the gravity block... The gantry is equipped with an outwardly protruding load-bearing part, which has a groove corresponding to the slide rail. The load-bearing part is slidably installed on the slide rail through the groove, allowing the gravity block to move along the slide rail when moving up and down with stable vertical travel. Safety clamps are installed at the bottom of the load-bearing parts on both sides, and the safety clamps are coupled to the slide rail. A speed limiter is installed at the top of the gantry, and the speed limiter is connected to the top of the gravity block through a rope. The speed limiter and safety clamps provide protection, and the speed limiter can be connected to an external control device to detect its running speed.

[0005] The aforementioned gravity block guide fixture for a gravity compressed air energy storage system has a distance measuring device installed at the top inner side of the gantry frame. This device measures the distance between the upper surface of the gravity block and the top of the gantry frame, preventing the gravity block from exceeding its travel limit when moving upwards or downwards. The device can also be used to perform emergency stops and alert staff via the control system.

[0006] The aforementioned gravity block guide fixture for a gravity compressed air energy storage system has a limit part provided at the inner bottom end of the gantry frame. The limit part extends inward from the slide rail. When the gravity block is out of control, the limit part can support the gravity block and prevent the gravity block from falling and causing equipment damage and personnel injury.

[0007] The aforementioned gravity block guide fixture for a gravity compressed air energy storage system has a hydraulic chamber located on the upper surface of the limiting part extending from the slide rail. A piston is installed inside the hydraulic chamber, a support rod is installed on the top of the piston, and a shoulder support is installed at the top of the support rod. A buffer spring is installed between the piston and the bottom surface of the hydraulic chamber. When the gravity block falls uncontrollably, it impacts the shoulder support, and the hydraulic oil in the hydraulic chamber and the buffer spring provide cushioning, reducing the damage caused by the uncontrolled descent of the gravity block.

[0008] The aforementioned gravity block guide fixture for a gravity compressed air energy storage system includes a detection unit on the upper surface of the shoulder support, which is hinged to one end of the shoulder support. A groove is formed in the middle of the upper surface of the shoulder support, and one end of an elastic component is fixedly installed in the groove. The other end of the elastic component extends upward from the groove and is placed at the bottom of the detection unit. A first contact point and a second contact point corresponding to the first contact point are provided at the other end of the detection unit. The first and second contacts are electrically connected to an external controller. When the gravity block descends, the shoulder support comes into contact with the detection unit, causing the first and second contacts to make contact and generate an electrical signal. This can be controlled by the control system to perform emergency stop or other operations and can also alert the operator.

[0009] The aforementioned gravity block guiding fixture for a gravity compressed air energy storage system has an annular frame fixedly installed on the top of the inner wall of the shaft, which surrounds the gravity block. Guide wheels are installed on the inner side of the annular frame, and multiple guide wheels are installed in contact with the surface of the shaft and surround the shaft, so as to guide and protect the gravity block part inside the shaft.

[0010] Compared with existing technologies, this utility model uses a gantry frame structure combined with a sliding rail guide device to support the gravity block, making the gravity block support robust and the stroke stable, thus solving the problem of unstable gravity block stroke in traditional compressed air energy storage systems. Simultaneously, it can detect the gravity block's running speed and stroke, and work with a speed limiter and safety clamp to provide protection, preventing rapid descent of the gravity block due to malfunctions such as air leakage, which could damage the equipment. Furthermore, the limiting part further strengthens the emergency protection measures during rapid descent of the gravity block, serving as a buffer, support, and alarm to ensure that no danger occurs when the gravity block falls uncontrollably and rapidly.
