Description

Technical Field

[0001] This invention relates to the field of compressed air energy storage technology, specifically to a composite process for steel-rubber composite materials used in the sealing of artificial chambers. Background Technology

[0002] Artificial caverns are underground caverns primarily used for purposes such as gas storage and compressed air energy storage. Specifically, artificial caverns are man-made underground caverns used for various purposes such as defense, storage, and living. These caverns typically have a large cross-section and a short length to meet different usage needs.

[0003] Currently, chambered gas storage facilities are mainly used in compressed air energy storage power stations. During operation, these facilities need to withstand compressed air pressures of up to 10-20 MPa, thus requiring extremely high sealing performance. However, existing technologies using sealing rings to seal the chambers present the following problems: 1. Due to the large diameter of the chamber, the corresponding sealing ring size is also large. When fixing large-diameter sealing rings, their flexibility makes it difficult for the upper half to fit snugly against the inner wall of the chamber, often requiring multiple manual fixations, resulting in low installation efficiency. 2. Using a single sealing ring is insufficient to meet the high-pressure, high-requirement sealing requirements of artificial chambers.

[0004] Therefore, the present invention provides a composite process for steel-rubber composite materials for sealing artificial chambers. Summary of the Invention

[0005] This invention provides a composite process for sealing artificial chambers using steel-rubber composite materials, which is used to seal a steel-rubber composite sealing structure into an artificial chamber. The steel-rubber composite sealing structure includes a circular plate, an L-shaped rubber sealing strip, a guiding mechanism, a pressing mechanism, and a threaded ring. The circular plate is fixed to the end of the artificial chamber, and the circular plate and the artificial chamber are sealed by the L-shaped rubber sealing strip.

[0006] A guide mechanism is provided on the side wall of the circular plate facing the interior of the artificial chamber. The guide mechanism includes a circular cylinder rotatably installed at the center of the side wall of the circular plate. Multiple circumferentially evenly distributed moving rods are slidably arranged on the outer wall of the circular cylinder. The end of each moving rod is rotatably connected to a guide wheel. A pressing mechanism is also provided on each moving rod. The threaded ring is used in conjunction with the pressing mechanism.

[0007] The composite process specifically includes the following steps: S1, fixing the circular plate to the end of the artificial chamber.

[0008] S2. Initially fix the free end of the rolled L-shaped rubber sealing tape to the artificial chamber and the circular plate.

[0009] S3. The guide wheels are moved by the synchronously outward moving rod until one of the guide wheels is in contact with the inner edge of the L-shaped rubber sealing strip.

[0010] S4. Rotate the annular cylinder, causing all guide wheels and pressing mechanisms to rotate. The pressing mechanism pulls the L-shaped rubber sealing strip to unwind, allowing the L-shaped rubber sealing strip to gradually adhere to the artificial chamber and circular plate along the annular area until the L-shaped rubber sealing strip forms a complete sealing ring structure. Then, cut the L-shaped rubber sealing strip.

[0011] S5. The pressing mechanism is pressed tightly against the L-shaped rubber sealing strip by the cooperation of the threaded ring and the pressing mechanism.

[0012] S6. Fix the circular plate to the guide mechanism.

[0013] S7. Heat and vulcanize the L-shaped rubber sealing strip to seal the space between the circular plate and the artificial chamber.

[0014] In one possible implementation, the end of the annular cylinder away from the circular plate is threadedly connected to a pusher, wherein the pusher consists of a threaded sleeve threaded to the outside of the annular cylinder and a circular plate integrally formed at the end of the threaded sleeve. A frustum block is provided inside the annular cylinder, the diameter of the end of the frustum block near the circular plate is smaller than the diameter of the end away from the circular plate, the frustum block and the circular plate are fixedly connected by a connecting rod, and the frustum block and the connecting rod can rotate relative to each other. The inclined outer wall of the frustum block is provided with a plurality of guide grooves evenly distributed in a circle, the cross-section of the guide grooves is T-shaped, and a guide block matching the cross-sectional shape is slidably arranged inside the guide groove. The end of the guide block away from the axis of the frustum block is fixedly connected to a corresponding moving rod.

[0015] In one possible implementation, the axis of the guide wheel is parallel to the axis of the annular cylinder, and the side of the guide wheel facing the circular plate is in contact with the circular plate.

[0016] In one possible implementation, the pressing mechanism includes a mounting ring, a rotating telescopic rod, a first pressure plate, a second pressure plate, and an arc-shaped slot. The mounting ring is fixedly installed on the side of the moving rod away from the circular plate. The axis of the mounting ring is parallel to or coincides with the axis of the guide wheel. A rectangular notch is provided on the side of the mounting ring facing the inner wall of the artificial chamber, extending to the end of the mounting ring away from the moving rod. The rotating telescopic rod is rotatably connected to the mounting ring via a rotating shaft, and the rotating telescopic rod can pass through the rectangular notch during rotation. The telescopic end of the rotating telescopic rod is fixedly connected to a first pressure plate, which has an arc-shaped plate structure, and the thickness of the first pressure plate gradually increases from the end near the circular plate to the end away from the circular plate. A second pressure plate is fixedly installed on the end of the first pressure plate near the circular plate, and the second pressure plate has an arc-shaped plate structure with a fixed thickness.

[0017] In one possible implementation, the pressing mechanism on one of the movable rods further includes a torsion spring, which is sleeved on the pivot of the rotating telescopic rod. One end of the torsion spring is fixedly connected to the rotating telescopic rod, and the other end of the torsion spring is fixedly connected to the inner wall of the mounting ring. The rotating telescopic rod connected to the torsion spring remains in an inclined state under the elastic force of the torsion spring, and the rotating telescopic rod is always located within the rectangular notch.

[0018] In one possible implementation, the outer walls of all mounting rings are provided with threaded grooves on both sides of the rectangular notch, the threaded grooves being centered on the axis of the annular cylinder, and all mounting rings are externally connected to a common threaded ring.

[0019] In one possible implementation, the steel-rubber composite sealing structure requires the cooperation of a heating mechanism during the sealing process. All the No. 1 pressure plates have arc-shaped slots on the side away from the circular plate. The heating mechanism includes a No. 2 heating plate inserted into the arc-shaped slot. The heating mechanism also includes multiple No. 1 heating plates evenly distributed circumferentially. Each No. 1 heating plate is in contact with two adjacent No. 2 pressure plates. The No. 1 heating plates and No. 2 heating plates are staggered, and adjacent No. 1 heating plates and No. 2 heating plates are connected by connecting components.

[0020] In one possible implementation, the connecting assembly includes a short tube fixed to the side of the second heating plate away from the circular plate, and a long tube fixedly connected to the side of the first heating plate away from the circular plate. The length of the long tube is greater than the length of the short tube, and the short tube and the long tube are fixedly connected by a connecting plate.

[0021] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0022] This invention utilizes the cooperation between a threaded ring and an installation ring to cause the rotating telescopic rod to tightly press the first and second pressure plates onto the L-shaped rubber sealing strip, thus providing strong mechanical pressure. A heating mechanism heats the first and second pressure plates, causing the L-shaped rubber sealing strip to gradually vulcanize, thereby sealing the artificial chamber and the circular plate. This invention combines mechanical pressing with vulcanization to improve the sealing effect. Furthermore, the invention uses a guiding mechanism in conjunction with one of the pressing mechanisms to pull the L-shaped rubber sealing strip into a sealing ring, reducing the difficulty of installing large-diameter sealing rings, minimizing manual intervention, and improving installation efficiency. It can also be adaptively adjusted in real time according to the actual diameter of the artificial chamber, avoiding the problem of weak sealing caused by mismatch between the sealing ring and the inner diameter of the artificial chamber.

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Please see Figure 1 , Figure 2 and Figure 3A composite process for sealing artificial chambers using steel-rubber composite materials is disclosed, which is used to seal a steel-rubber composite sealing structure into an artificial chamber 1. The steel-rubber composite sealing structure includes a circular plate 2, an L-shaped rubber sealing strip 3, a guiding mechanism 4, a pressing mechanism 5, and a threaded ring 7. The circular plate 2 is fixed to the end of the artificial chamber 1, and the circular plate 2 and the artificial chamber 1 are sealed together by the L-shaped rubber sealing strip 3.

[0035] Please see Figure 4 and Figure 5 A guide mechanism 4 is provided on the side wall of the circular plate 2 facing the interior of the artificial chamber 1. The guide mechanism 4 includes a circular annular cylinder 41 rotatably mounted at the center of the side wall of the circular plate 2. A pusher 42 is threadedly connected to the end of the circular annular cylinder 41 away from the circular plate 2. The pusher 42 consists of a threaded sleeve threaded to the outside of the circular annular cylinder 41 and a circular plate integrally formed at the end of the threaded sleeve. A frustum top block 44 is provided inside the circular annular cylinder 41. The diameter of the end of the frustum top block 44 near the circular plate 2 is smaller than the diameter of the end away from the circular plate 2. The frustum top block 44 and the circular plate are fixedly connected by a connecting rod 43, and the frustum top block 44 and the connecting rod 43 can rotate relative to each other. The inclined outer wall of the frustum top block 44 has multiple circumferentially evenly distributed... The guide grooves 45 are evenly distributed and have a T-shaped cross-section, meaning that the opening width of the guide groove 45 is smaller than the width of the side of the guide groove 45 closest to the axis of the frustum top block 44. A guide block 47 matching the cross-sectional shape is slidably disposed inside the guide groove 45. A moving rod 46 is fixedly connected to one end of the guide block 47 away from the axis of the frustum top block 44. The moving rod 46 slides through the side wall of the annular cylinder 41 to the outside. A rotating shaft is rotatably mounted on one end of the moving rod 46 extending out of the annular cylinder 41. The rotating shaft is located on the side of the moving rod 46 closest to the circular plate 2, and the axis of the rotating shaft is parallel to the axis of the annular cylinder 41. A guide wheel 48 is fixedly sleeved on the outside of the rotating shaft, and the side of the guide wheel 48 facing the circular plate 2 is in contact with the circular plate 2.

[0036] When initially installing the L-shaped rubber sealing strip 3, the pusher 42 needs to be rotated first, so that the pusher 42 moves closer to the circular plate 2 along the axis of the annular cylinder 41. The pusher 42 then drives the frustum top block 44 to move closer to the circular plate 2 simultaneously through the connecting rod 43. During the movement of the frustum top block 44, the guide block 47 slides relative to the guide groove 45. Multiple moving rods 46 move outward synchronously under the drive of the guide block 47, so that multiple guide wheels 48 move to a predetermined position. This position depends specifically on the width of the section where the L-shaped rubber sealing strip 3 is in contact with the circular plate 2.

[0037] Please see Figure 4 , Figure 6 and Figure 7The movable rod 46 is also equipped with a pressing mechanism 5, which includes a mounting ring 51, a rotating telescopic rod 52, a first pressure plate 53, a second pressure plate 54, and an arc-shaped slot 55. A mounting ring 51 is fixedly mounted on the side of the movable rod 46 away from the circular plate 2. The axis of the mounting ring 51 is parallel to or coincides with the axis of the guide wheel 48. A rectangular notch is provided on the side of the mounting ring 51 facing the inner wall of the artificial chamber 1, extending to the end of the mounting ring 51 away from the movable rod 46. A rotating telescopic rod 52 is rotatably connected to the mounting ring 51 via a rotating shaft. The telescopic rod 52 can pass through the rectangular notch during rotation. A first pressure plate 53 is fixedly connected to the telescopic end of the telescopic rod 52. The first pressure plate 53 has an arc-shaped plate structure, and the thickness of the first pressure plate 53 gradually increases from the end near the circular plate 2 to the end away from the circular plate 2. A second pressure plate 54 is fixedly installed at the end of the first pressure plate 53 near the circular plate 2. The second pressure plate 54 has an arc-shaped plate structure with a fixed thickness.

[0038] It should be noted that the pressing mechanism 5 on one of the moving rods 46 also includes a torsion spring (not shown in the figure). The torsion spring is sleeved on the rotating shaft of the rotating telescopic rod 52, and one end of the torsion spring is fixedly connected to the rotating telescopic rod 52, while the other end of the torsion spring is fixedly connected to the inner wall of the mounting ring 51. The rotating telescopic rod 52 connected to the torsion spring remains in an inclined state under the elastic force of the torsion spring. The rotating telescopic rods 52 on the other pressing mechanisms 5 are all freely rotatably connected. That is, in the initial state, the rotating telescopic rods 52 located in the upper semicircle can rotate towards the axis closer to the artificial chamber 1 under their own weight or manual actuation. The rotating telescopic rods 52 located in the lower semicircle are divided into two states: one is flipped away from the axis of the artificial chamber 1 under their own weight, and the other is rotated towards the axis of the artificial chamber 1 under manual actuation. During the rotation of the guide mechanism 4, the state of each rotating telescopic rod 52 changes in real time.

[0039] During operation, the free end of the L-shaped rubber sealing strip 3 is first fixed to the inner wall of the artificial chamber 1 and the side wall of the circular plate 2 by adhesive bonding. The free end is preferably fixed in the upper semi-circular area of ​​the artificial chamber 1. The pressing mechanism 5 with torsion spring corresponds to the free end of the L-shaped rubber sealing strip 3. Then, keeping the annular cylinder 41 stationary, the pushing component 42 is rotated to make all the guide wheels 48 move outward synchronously. The guide wheel 48 corresponding to the free end of the L-shaped rubber sealing strip 3 is then in contact with the inner annular surface of the L-shaped rubber sealing strip 3. The remaining guide wheels 48 reach the predetermined position. All the guide wheels 48 are located on the same circular trajectory. The annular area between this circular trajectory and the inner diameter of the artificial chamber 1 is the area that accommodates the L-shaped rubber sealing strip 3. At this time, the first pressure plate 53 in the pressing mechanism 5 with torsion spring is in contact with the artificial chamber 1. The second pressure plate 54 of the pressing mechanism 5 with torsion spring contacts the inner wall of the L-shaped rubber sealing strip 3 and contacts the inner wall of the circular plate 2. The rotating pusher 42 stops rotating. At this time, the pusher 42 and the annular cylinder 41 remain fixed. Then, the annular cylinder 41 is rotated by external force. The annular cylinder 41 will drive all the guide wheels 48 and the pressing mechanism 5 to rotate. The pressing mechanism 5, which is initially attached to the free end of the L-shaped rubber sealing strip 3, will pull the L-shaped rubber sealing strip 3 to unwind during subsequent movement. This will cause the L-shaped rubber sealing strip 3 to gradually attach to the artificial chamber 1 and the circular plate 2 along the annular area until the L-shaped rubber sealing strip 3 forms a complete sealing ring structure. During the process of the L-shaped rubber sealing strip 3 forming a sealing ring structure, if the pressing mechanism 5 encounters an obstacle to the movement of the L-shaped rubber sealing strip 3, the rotating telescopic rod 52 will be manually moved.

[0040] It should be noted that after the L-shaped rubber sealing strip 3 is formed into a sealing ring structure, its end is cut off. The two ends of the L-shaped rubber sealing strip 3 can be joined together, or there can be a margin so that the two ends overlap. The rotation process of the annular cylinder 41 can be driven by an external motor. After the annular cylinder 41 is fixed, the external motor needs to be removed from the annular cylinder 41.

[0041] Please see Figure 3 and Figure 6All mounting rings 51 have threaded grooves on both sides of the rectangular notch on their outer walls. The threaded grooves are centered on the axis of the annular cylinder 41. All mounting rings 51 are connected to a threaded ring 7 by a common thread. During operation, all rotating telescopic rods 52 need to be rotated to the side away from the axis of the annular cylinder 41. Then, the threaded ring 7 is gradually threaded onto the outside of all mounting rings 51, so that the threaded ring 7 gradually moves closer to one side of the circular plate 2. During the movement of the threaded ring 7, all rotating telescopic rods 52 will continue to rotate. In turn, the rotating telescopic rods 52 will drive all the first pressure plates 53 to squeeze the section of the L-shaped rubber sealing strip 3 that is attached to the inner wall of the artificial chamber 1, and all the second pressure plates 54 to squeeze the section of the L-shaped rubber sealing strip 3 that is attached to the inner wall of the circular plate 2.

[0042] It should be noted that the inner ring surface of the threaded ring 7 will fit against the part of the rotating telescopic rod 52 that is rotatably connected to the mounting ring 51, while the outer ring surface of the threaded ring 7 will push against the telescopic part of the rotating telescopic rod 52, thus preventing the rotating telescopic rod 52 from being retracted due to the pressure of the No. 1 pressure plate 53 on the L-shaped rubber sealing strip 3. This ensures that the force on the L-shaped rubber sealing strip 3 is a rigid force, and the corresponding squeezing force acting on the L-shaped rubber sealing strip 3 depends on the rotation angle of the threaded ring 7.

[0043] Please see Figure 7 , Figure 8 and Figure 9 The steel-rubber composite sealing structure requires the cooperation of a heating mechanism 6 during the sealing process. All the first pressure plates 53 have arc-shaped slots 55 on the side away from the circular plate 2. The heating mechanism 6 includes a second heating plate 62 inserted into the arc-shaped slot 55. The heating mechanism 6 also includes multiple circumferentially evenly distributed first heating plates 61. The first heating plate 61 is in contact with two adjacent second pressure plates 54, that is, the first heating plate 61 and the second heating plate 62 are staggered. Adjacent first heating plates 61 and second heating plates 62 are connected by a connecting component 63. The connecting component 63 includes a short tube 632 fixed to the side of the second heating plate 62 away from the circular plate 2. A long tube 631 is fixedly connected to the side of the first heating plate 61 away from the circular plate 2. The length of the long tube 631 is greater than the length of the short tube 632, and the short tube 632 and the long tube 631 are fixedly connected by a connecting plate 633.

[0044] During the process of inserting all the No. 2 heating plates 62 into the arc-shaped slots 55, the No. 2 heating plates 62 will drive the No. 1 heating plate 61 to approach the No. 2 pressure plate 54 through the connecting component 63, and gradually fit into the No. 2 pressure plate 54. The gap between two adjacent No. 1 heating plates 61 is blocked by the rotating telescopic rod 52, while the gap between two adjacent No. 2 pressure plates 54 is covered by the No. 1 heating plates 61 pressed on the two No. 2 pressure plates 54.

[0045] It should be noted that the heating surface of the first heating plate 61 is located on the side close to the second pressure plate 54, while the heating surface of the second heating plate 62 is located on the side close to the inner wall of the artificial chamber 1. The arc-shaped slot 55 and the second pressure plate 54 are both made of metal, which can provide strong mechanical pressing and conduct heat to the L-shaped rubber sealing strip 3 for heating and vulcanizing the L-shaped rubber sealing strip 3.

[0046] Please see Figure 1 A composite process for sealing artificial chambers using steel-rubber composite materials specifically includes the following steps:

[0047] S1. Fix the circular plate 2 to the end of the artificial chamber 1 by welding or bolting.

[0048] S2. Pull out the rolled L-shaped rubber sealing strip 3 a certain distance, and use adhesive to stick the free end of the L-shaped rubber sealing strip 3 to the top of the inner wall of the artificial chamber 1, and use adhesive to fix the free end of the L-shaped rubber sealing strip 3 to the circular plate 2.

[0049] S3. Keep the annular cylinder 41 stationary and rotate the pusher 42 so that all the guide wheels 48 move outward synchronously until one of the guide wheels 48 is in contact with the inner edge of the L-shaped rubber sealing strip 3.

[0050] S4. Rotate the annular cylinder 41, causing the annular cylinder 41 to drive all the guide wheels 48 and the pressing mechanism 5 to rotate. During the movement, the pressing mechanism 5 equipped with torsion springs pulls the L-shaped rubber sealing strip 3 to unwind, so that the L-shaped rubber sealing strip 3 gradually adheres to the artificial chamber 1 and the circular plate 2 along the annular area until the L-shaped rubber sealing strip 3 forms a complete sealing ring structure. Then, the L-shaped rubber sealing strip 3 is cut.

[0051] S5. Flip all the rotating telescopic rods 52 to the side away from the axis of the annular cylinder 41. Then, gradually thread the threaded ring 7 onto the outside of all the mounting rings 51. As the threaded ring 7 moves, it will push all the rotating telescopic rods 52 to continue rotating, so that all the first pressure plate 53 and the second pressure plate 54 are pressed tightly onto the L-shaped rubber sealing strip 3.

[0052] S6. Since the guide wheel 48 no longer needs to move radially or circumferentially along the annular cylinder 41, the guide wheel 48 is welded to the circular plate 2 to prevent the annular cylinder 41 or the pusher 42 from being rotated by external force collision, which would cause the position of the guide wheel 48 to change, thereby affecting the pressing pressure of the first pressure plate 53 and the second pressure plate 54 on the L-shaped rubber sealing strip 3.

[0053] S7. Insert the second heating plate 62 into the corresponding arc-shaped slot 55, and press the first heating plate 61 onto the second pressure plate 54. Power on the first heating plate 61 and the second heating plate 62 so that the first heating plate 61 heats the second pressure plate 54 and the second heating plate 62 heats the first pressure plate 53, thereby indirectly heating and vulcanizing the L-shaped rubber sealing strip 3, so that the L-shaped rubber sealing strip 3, the circular plate 2, and the artificial chamber 1 are sealed. After sealing is completed, remove the heating mechanism 6.

[0054] In embodiments of the present invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

For example, they can refer to a fixed connection, a detachable connection, an integral connection, or a sliding connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
