Description

Technical Field

[0001] The invention relates to the technical field of compressed air energy storage, and in particular to a composite process of steel-rubber composite materials for artificial chamber sealing. Background Art

[0002] An artificial chamber is an underground cavern, mainly used for gas storage, compressed air energy storage and other purposes. Specifically, an artificial chamber is an artificially built underground cavern, used for defense, storage, living and other purposes. These caverns usually have a large cross-section and a short length, which can meet different usage requirements.

[0003] At present, chamber gas storage is mainly used in compressed air energy storage power stations. When the compressed air energy storage power station is in operation, the chamber gas storage needs to withstand a maximum compressed air pressure of 10-20MPa, so the sealing requirements for the chamber are very high; and when the chamber is sealed by a sealing ring in the prior art, there are still the following problems: First, due to the large diameter of the chamber, the corresponding sealing ring size will also be large. When fixing the large diameter sealing ring, due to its flexible nature, it will make the upper half of the sealing ring difficult to fit with the inner wall of the chamber, and it often requires multiple manual fixations, resulting in low installation efficiency of the sealing ring; Second, when a single sealing ring is used for sealing, it is difficult to meet the high-pressure and high-requirement sealing environment of the artificial chamber.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full 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 improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] See also Figure 1 , Figure 2 and Figure 3A composite process of steel-rubber composite materials for sealing an artificial chamber 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 belt 3, a guiding mechanism 4, a pressing mechanism 5 and a threaded ring 7. The circular plate 2 is fixed at the end of the artificial chamber 1, and the circular plate 2 and the artificial chamber 1 are sealed by the L-shaped rubber sealing belt 3.

[0035] See also Figure 4 and Figure 5 A guide mechanism 4 is provided on the side of the side wall of the circular plate 2 facing the interior of the artificial chamber 1, and the guide mechanism 4 includes a circular ring cylinder 41 rotatably mounted at the center of the side wall of the circular plate 2, and a pusher 42 is threadedly connected to the end of the circular ring cylinder 41 away from the circular plate 2, wherein the pusher 42 is composed of a threaded sleeve threadedly connected to the outside of the circular ring cylinder 41 and a circular plate integrally formed at the end of the threaded sleeve, and a truncated cone top block 44 is provided inside the circular ring cylinder 41, and the diameter of the end of the truncated cone top block 44 close to the circular plate 2 is smaller than the diameter of the end away from the circular plate 2, the truncated cone top block 44 and the circular plate are fixedly connected by a connecting rod 43, and the truncated cone top block 44 and the connecting rod 43 can rotate relative to each other, and the inclined outer wall of the truncated cone top block 44 is provided with a plurality of circumferentially uniform The guide grooves 45 are evenly distributed, and the cross-section of the guide grooves 45 is T-shaped, that is, the opening width of the guide grooves 45 is smaller than the width of the guide grooves 45 on the side close to the axis of the truncated cone top block 44. The guide grooves 45 are internally slidably provided with guide blocks 47 matching their cross-sectional shape. The end of the guide block 47 away from the axis of the truncated cone top block 44 is fixedly connected with a moving rod 46, and the moving rod 46 slides through the side wall of the annular cylinder 41 to the outside. The end of the moving rod 46 extending out of the annular cylinder 41 is rotatably installed with a rotating shaft, which is located on the side of the moving rod 46 close to the circular plate 2, and the axis of the rotating shaft is parallel to the axis of the annular cylinder 41. The external fixed sleeve of the rotating shaft is provided with a guide wheel 48, and the guide wheel 48 is in contact with the circular plate 2 on the side facing the circular plate 2.

[0036] When initially installing the L-shaped rubber sealing strip 3, it is first necessary to rotate the pusher 42 so that the pusher 42 approaches the circular plate 2 along the axial direction of the annular cylinder 41, and the pusher 42 drives the truncated cone top block 44 to approach the circular plate 2 synchronously through the connecting rod 43. During the movement of the truncated cone top block 44, the guide block 47 and the guide groove 45 slide relative to each other, and the multiple moving rods 46 move outward synchronously driven by the guide block 47, so that the multiple guide wheels 48 move to a predetermined position, which depends on the width of a section where the L-shaped rubber sealing strip 3 fits the circular plate 2.

[0037] See also Figure 4 , Figure 6 and Figure 7The moving rod 46 is also provided with a pressing mechanism 5, and the pressing mechanism 5 includes a mounting ring 51, a rotating telescopic rod 52, a first pressing plate 53, a second pressing plate 54 and an arc-shaped slot 55. The moving rod 46 is fixedly provided with a mounting ring 51 on the side away from the circular plate 2, and the axis of the mounting ring 51 is parallel to or coincides with the axis of the guide wheel 48. The mounting ring 51 is provided with a rectangular notch on the side facing the inner wall of the artificial chamber 1, and the rectangular notch extends to the end of the mounting ring 51 away from the moving rod 46. A rotatable telescopic rod 52 is rotatably connected to the mounting ring 51 via a rotating shaft, and the rotatable 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 rotatable telescopic rod 52. The first pressure plate 53 is an arc-shaped plate-like structure, and the thickness of the first pressure plate 53 gradually increases from the end close to 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 No. 1 pressure plate 53 close to the circular plate 2, and the No. 2 pressure plate 54 is an arc-shaped plate-like 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), which 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, and 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 maintains an inclined state under the elastic force of the torsion spring, and the rotating telescopic rods 52 on the remaining pressing mechanisms 5 are all freely rotatable connections, that is, in the initial state, the rotating telescopic rods 52 located in the upper semicircle can be rotated toward the axial direction close to the artificial chamber 1 under the action of their own weight or manual manipulation, while the rotating telescopic rods 52 located in the lower semicircle are divided into two states, one of which is flipped toward the axial direction away from the artificial chamber 1 under the action of its own weight, and the other is rotated toward the axial direction close to the artificial chamber 1 under the action of manual manipulation. During the rotation of the guide mechanism 4, the state of each rotating telescopic rod 52 changes in real time.

[0039] During operation, first, the free end of the L-shaped rubber sealing belt 3 is fixed to the inner wall of the artificial chamber 1 and the side wall of the circular plate 2 by gluing. The fixed position of the free end is preferably in the upper semicircular area of ​​the artificial chamber 1, and the pressing mechanism 5 with a torsion spring corresponds to the free end of the L-shaped rubber sealing belt 3. Then, the annular cylinder 41 is kept stationary and the pusher 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 belt 3 fits with the inner ring surface of the L-shaped rubber sealing belt 3, and the remaining guide wheels 48 reach a predetermined position. All the guide wheels 48 are located on the same circular trajectory, and the annular area between the circular trajectory and the inner diameter of the artificial chamber 1 is the area for accommodating the L-shaped rubber sealing belt 3; at this time, the No. 1 pressing plate 53 in the pressing mechanism 5 with a torsion spring fits with the artificial chamber 1 in the L-shaped rubber sealing belt 3. The pusher 42 stops rotating, and the pusher 42 and the annular cylinder 41 remain fixed at this time. Then the annular cylinder 41 is rotated by external force, and the annular cylinder 41 will drive all the guide wheels 48 and the pressing mechanism 5 to rotate. The pressing mechanism 5 that is initially in contact with the free end of the L-shaped rubber sealing belt 3 will pull the L-shaped rubber sealing belt 3 to unwind during the subsequent movement, so that the L-shaped rubber sealing belt 3 gradually fits with the artificial chamber 1 and the circular plate 2 along the annular area until the L-shaped rubber sealing belt 3 forms a complete sealing ring structure. In the process of the L-shaped rubber sealing belt 3 forming the sealing ring structure, if the pressing mechanism 5 that hinders the movement of the L-shaped rubber sealing belt 3 is encountered, the rotating telescopic rod 52 is manually moved.

[0040] It should be noted that after the L-shaped rubber sealing belt 3 forms a sealing ring structure, its ends are cut off. The head and tail ends of the L-shaped rubber sealing belt 3 can be just butt-jointed, or a margin can be left so that the head and tail ends overlap. The rotation process of the annular cylinder 41 can be driven by an external motor. When the annular cylinder 41 is fixed, the external motor and the annular cylinder 41 need to be removed.

[0041] See also Figure 3 and Figure 6, the outer walls of all the mounting rings 51 are provided with threaded grooves on both sides of the rectangular notch, and the threaded grooves are centered on the axis of the circular ring tube 41. The outsides of all the mounting rings 51 are commonly threadedly connected with a threaded ring 7. When working, all the rotating telescopic rods 52 need to be flipped to the side away from the axis of the circular ring tube 41, and then the threaded ring 7 is gradually threadedly sleeved on the outside of all the mounting rings 51, so that the threaded ring 7 gradually approaches one side of the circular plate 2. During the movement of the threaded ring 7, all the rotating telescopic rods 52 will be pushed to continue rotating, and then the rotating telescopic rods 52 will drive all the No. 1 pressure plates 53 to squeeze a section of the L-shaped rubber sealing belt 3 that fits the inner wall of the artificial chamber 1, and all the No. 2 pressure plates 54 squeeze a section of the L-shaped rubber sealing belt 3 that fits 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 with 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 the telescopic part of the rotating telescopic rod 52, thereby avoiding the rotating telescopic rod 52 being forced to retract due to the squeezing of the L-shaped rubber sealing belt 3 by the No. 1 pressure plate 53, ensuring that the force squeezing the L-shaped rubber sealing belt 3 is a rigid force, and the corresponding squeezing force acting on the L-shaped rubber sealing belt 3 depends on the rotation angle of the threaded ring 7.

[0043] See also Figure 7 , Figure 8 and Fig. 9 The steel-rubber composite sealing structure also requires the cooperation of the heating mechanism 6 during the sealing process. All the No. 1 pressure plates 53 are provided with an arc slot 55 on the side away from the circular plate 2. The heating mechanism 6 includes a No. 2 heating plate 62 inserted in the arc slot 55. The heating mechanism 6 also includes a plurality of No. 1 heating plates 61 uniformly distributed in the circumferential direction. The No. 1 heating plate 61 is fitted with two adjacent No. 2 pressure plates 54, that is, the No. 1 heating plate 61 and the No. 2 heating plate 62 are staggered, and the adjacent No. 1 heating plate 61 and the No. 2 heating plate 62 are connected by a connecting assembly 63; the connecting assembly 63 includes a short tube 632 fixed to the side of the No. 2 heating plate 62 away from the circular plate 2, and the No. 1 heating plate 61 is fixedly connected to the side away from the circular plate 2 with a long tube 631, 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 all No. 2 heating plates 62 being inserted into the arc-shaped slots 55, the No. 1 heating plate 61 will be driven by the connecting assembly 63 to approach the No. 2 pressing plate 54 and gradually fit with the No. 2 pressing plate 54. The space between two adjacent No. 1 heating plates 61 is blocked by the rotating telescopic rod 52, while the gap between two adjacent No. 2 pressing plates 54 is covered by the No. 1 heating plate 61 pressed on the two No. 2 pressing plates 54.

[0045] It should be noted that the heating surface of the No. 1 heating plate 61 is located on the side close to the No. 2 pressure plate 54, and the heating surface of the No. 2 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 No. 2 pressure plate 54 are both made of metal materials, which can not only provide strong mechanical pressure, but also conduct heat to the L-shaped rubber sealing belt 3 to heat and vulcanize the L-shaped rubber sealing belt 3.

[0046] See also Figure 1 A composite process of steel-rubber composite materials for artificial chamber sealing, specifically comprising 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 tape 3 for a distance, stick the free end of the L-shaped rubber sealing tape 3 to the top of the inner wall of the artificial chamber 1 by gluing, and fix the free end of the L-shaped rubber sealing tape 3 to the circular plate 2 by gluing.

[0049] S3, keeping the annular cylinder 41 stationary and rotating the pusher 42 to make all the guide wheels 48 move outward synchronously until one of the guide wheels 48 fits with the inner edge of the L-shaped rubber sealing belt 3.

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

[0051] S5. All the rotating telescopic rods 52 are flipped to the side away from the axis of the circular tube 41, and then the threaded ring 7 is gradually threadedly sleeved on the outside of all the mounting rings 51. During the movement, the threaded ring 7 will push all the rotating telescopic rods 52 to continue rotating, so that all the No. 1 pressure plates 53 and No. 2 pressure plates 54 are tightly pressed on the L-shaped rubber sealing belt 3.

[0052] S6. Since the guide wheel 48 no longer needs to move along the radial or circumferential direction of 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 rotating due to external collision, causing the position of the guide wheel 48 to change, thereby affecting the pressing force of the No. 1 pressure plate 53 and the No. 2 pressure plate 54 on the L-shaped rubber sealing belt 3.

[0053] S7. Insert the No. 2 heating plate 62 into the corresponding arc-shaped slot 55, and press the No. 1 heating plate 61 on the No. 2 pressure plate 54. Power is applied to the No. 1 heating plate 61 and the No. 2 heating plate 62, so that the No. 1 heating plate 61 heats the No. 2 pressure plate 54, and the No. 2 heating plate 62 heats the No. 1 pressure plate 53, thereby indirectly heating and vulcanizing the L-shaped rubber sealing belt 3, so that the L-shaped rubber sealing belt 3 and the circular plate 2 and the artificial chamber 1 are sealed. After the sealing is completed, take out the heating mechanism 6.
