It should be noted that: unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. Like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 to 8, in this embodiment, a split sealing device is provided, which includes a first annular structural member 1, a second annular structural member 2, and an inner sealing assembly 3.

As an application example, when the original seal on the outer peripheral surface of the existing columnar structural member 4 fails, and the upper part of the columnar structural member 4 can pass freely, the assembled sealing device in the embodiment can be directly added at this time to seal the peripheral surface of the outer peripheral surface of the columnar structural member 4, and meanwhile, the disassembly and reinstallation of the original parts can be avoided, so that the assembly sealing device has higher efficiency compared with large-scale equipment.

At this time, the first annular structural member 1, the second annular structural member 2 and the inner sealing assembly 3 may be in a closed annular structure, and may be installed by being sleeved from above the columnar structural member 4 to a position where sealing is required.

As a preferable solution, the first annular structural member 1 is sleeved on the outer side of the columnar structural member 4, and the inner sealing component 3 is also sleeved on the outer side of the columnar structural member 4 and is located on the inner side of the first annular structural member 1; the second annular structural member 2 is sleeved on the outer side of the columnar structural member 4 and is located above the first annular structural member 1 and the inner sealing assembly 3, and the joint of the inner sealing assembly 3 and the first annular structural member 1 is located in the coverage range of the second annular structural member 2 along the vertical direction.

During installation, the inner seal assembly 3 will transition from the opposite natural state to the opposite compressed state. For example, when the second annular structural member 2 is not fastened to the first annular structural member 1, the inner seal assembly 3 is in an opposite natural state, and the top end of the inner seal assembly 3 is higher than the top end of the first annular structural member 1; when the second annular structural member 2 and the first annular structural member 1 are fastened and installed with each other, the second annular structural member 2 applies downward pressure to the inner sealing assembly 3 to compress the inner sealing assembly 3, and the inner sealing assembly 3 deforms in a compressed state and extends out of the inner side of the second annular structural member 2, so that the second annular structural member 2 is tightly attached to the columnar structural member 4, and circumferential sealing of the columnar structural member 4 is achieved.

In practice, since the inner seal assembly 3 and the first annular structural member 1 are both disposed on a mounting plane, the mounting plane described herein is typically the end face of the component on which the original seal is mounted; therefore, under the action of the second annular structural member 2, the inner sealing assembly 3 is compressed, and a certain end face sealing effect can be achieved between the bottom of the inner sealing assembly 3 and the installation plane. Therefore, the resealing operation at the sealed node of the columnar structural member 4 can be well realized, the whole operation is simpler and more convenient, especially when the sealing failure maintenance of large-scale equipment is handled, the problems of troublesome disassembly, large workload and the like existing in the process of disassembling the original sealing component can be effectively avoided, the operation efficiency is higher, and the popularization and the application are convenient.

As an example of one of the applications, when the existing columnar structure 4 has a failure in sealing the original peripheral surface, and there is a fixing obstacle above the columnar structure 4, for example, the columnar structure 4 is a pressure pipe, and the pressure pipe penetrates from a structural plate or even a wall, and the operation space is limited.

In this case, the first annular structural member 1 and the second annular structural member 2 are formed by splicing; for example, the first annular structural member 1 is formed by splicing at least two first arc-shaped plates 11, and the second annular structural member 2 is formed by splicing at least two second arc-shaped plates 21. By means of the splicing forming mode, the whole device can be suitable for the situation that the operation space is limited, and the application range can be wider. In this case, the inner seal assembly 3 may be cut and then bonded.

As a preferred solution, in this embodiment, the splicing surface of the first arcuate plate 11 and/or the second arcuate plate 21 is provided with a positioning pin hole 111, and the positioning pin hole 111 may be used for plugging and installing a positioning pin (not shown in the drawing), so that the degree of alignment between the two first arcuate plates 11 and/or the two second arcuate plates 21 during splicing may be more precise, for example, the flatness of the spliced rear end surface may be better, so that the tight fitting between the first annular structural member 1 and the second annular structural member 2 may be further facilitated, and meanwhile, the pressure of the second annular structural member 2 acting on the inner sealing assembly 3 may be more uniform, and the sealing effect may be better.

Further, in this embodiment, corresponding connection lugs 12 are disposed between the two first arcuate plates 11, and fixing holes 121 through which fasteners can be inserted are disposed on the connection lugs 12, and the fasteners can be bolts. The fastening pieces penetrate through the fixing holes 121, so that the two first arc plates 11 are fixed after being spliced, and the stability of the installation state is ensured.

As a preferable solution, a groove structure 13 is provided at the top end of the first annular structural member 1, a convex ring structure 22 corresponding to the groove structure 13 is provided on the second annular structural member 2, and the relative installation limit between the second annular structural member 2 and the first annular structural member 1 can be realized by embedding the convex ring structure 22 into the groove structure 13.

In this embodiment, the groove structure 13 is disposed inside the first annular structural member 1, and the inner sealing component 3 at least partially overlaps the convex ring structure 22 along the vertical direction. The groove structure 13 is arranged on the inner side of the first annular structural member 1, and the final step structure is formed, so that compared with the mode of forming a groove in the middle of the first annular structural member 1, the manufacturing and forming of the first annular structural member 1 and the second annular structural member 2 can be facilitated, the cost is reduced, and the forming width is convenient to control; meanwhile, the convex ring structure 22 not only cooperates with the groove structure 13 to serve as a limiting structure, but also serves as a function of compressing the inner sealing assembly 3, so that the required forming height of the inner sealing assembly 3 can be reduced, and the application cost can be reduced.

Further, in this embodiment, the first annular structural member 1 and the second annular structural member 2 are provided with corresponding mounting holes 14 through which fasteners pass, the mounting holes 14 are all penetrating, and the fasteners may also be in the form of bolts. By arranging the fastener in the mounting hole 14 in a penetrating way, the whole device can be conveniently mounted and fixed on a mounting plane through the fastener, and the reliability after mounting is improved; at the same time, the device is convenient for matching installation and use when the prior installation plane is provided with the screw connection hole, for example, the fastener is screwed on the prior screw connection hole after passing through the installation hole 14.

As an example of one application, when the original sealing structure is not detached, the bolts in the original screw holes are not generally detached, and therefore, the screw holes are generally rearranged on the mounting plane so as to facilitate the mounting connection through the fasteners arranged in the mounting holes 14, and at the same time, the fixation of the whole device is realized. For the original fastener, if the end part of the original fastener is convexly arranged on the installation plane, the first annular structural member 1 and/or the second annular structural member 2 can be provided with the avoidance groove 15, so that the whole device can be more closely attached after being installed.

In this embodiment, an annular groove 16 is provided on the bottom end surface of the first annular structural member 1 for sleeving the sealing ring 5, and for the above different application situations, the sealing ring 5 may be selected as an integral sealing ring 5, and the sealing ring 5 may be cut and then bonded into a whole.

Further, in this embodiment, an inner flanging structure 161 is disposed at the opening of the annular groove 16, and the inner flanging structure 161 is disposed on the side surface of the annular groove 16 near the inner ring side of the first annular structural member 1. The annular groove 16 can facilitate the arrangement of the sealing ring 5 so as to achieve a further end face sealing effect between the whole device and the installation plane; the inner flange 161 is disposed so that the sealing ring 5 will not easily fall off when being mounted in the annular groove 16, thereby improving the assembly efficiency.

Furthermore, the inner seal assembly 3 comprises a bottom seal gasket 31, a top seal gasket 32 and several middle seals 33.

As a preferred solution, the middle seal 33 comprises at least one bending section, as in the present embodiment, the cross-section of the middle seal is V-shaped; the middle sealing members 33 are overlapped with each other, a space for installing the middle sealing members 33 after overlapping is formed between the bottom sealing gasket 31 and the top sealing gasket 32, and the shapes of the contact surfaces among the bottom sealing gasket 31, the top sealing gasket 32 and the middle sealing member 33 are matched, so that the air tightness of the whole inner sealing assembly 3 in a compressed state can be better.
