Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline leak sealing technology, and in particular to a device for installing leak-proof plugs. Background Technology
[0002] Pipeline valve leakage is a common accident in industries such as power and heating. During emergency repairs, it is essential to shut off the upstream pressure valve to minimize losses and the spread of the accident. However, when the upstream pressure valve cannot be shut off, or when such a situation occurs, pressurized pipeline repairs and leak sealing must be carried out.
[0003] In existing technologies, such as Figure 1 As shown, a clamping tool (not shown) is typically used to secure the leak-proof plug 10, ensuring that the plug 10 and the pipe to be sealed are pressed together. The clamping tool is then tightened, causing the threads on the connecting rod 101 to gradually move into the pipe. This achieves the leak-proofing of the pipe.
[0004] While this method allows the leak-proof plug 10 to be placed on the pipe to be sealed, as the leak-proof plug 10 moves into the pipe, the outward force of the fluid and the inward force exerted by the leak-proof plug on the fluid will cause the fluid to splash around in the circumference and may also splash onto the operator, which can easily pollute the surrounding environment and may also injure the operator. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a device for installing leak-proof plugs. To achieve the above objectives, this utility model adopts the following technical solution:
[0006] A device for installing a leak-proof plug includes a fixing mechanism for fixing the leak-proof plug to itself, and a drainage mechanism for blocking fluid to prevent circumferential splashing.
[0007] The fixing mechanism includes a receiving portion for receiving the leak-proof plug, and the drainage mechanism includes a blocking portion surrounding the receiving portion. The radial distance of the inner side of the blocking portion is set to gradually increase in the direction away from the receiving portion, so that after the fluid and the blocking portion come into contact with each other, the fluid moves in the direction away from the receiving portion under the action of the blocking portion.
[0008] Furthermore, the receiving portion includes a limiting groove configured to allow the leak-proof plug to engage with each other in the circumferential direction. The limiting groove is provided in a plurality of such grooves and is distributed sequentially along the axial direction so that each limiting groove can accommodate leak-proof plugs of different sizes.
[0009] Furthermore, the fixing mechanism also includes a fixing part that passes through the receiving part and allows radial movement in the limiting groove, for selectively fixing the leak-proof plug in the limiting groove.
[0010] Furthermore, the fixing part includes a threaded hole that passes radially through the receiving part, and a threaded rod disposed in the threaded hole and allowing it to engage with the threaded hole, so that the threaded rod can move radially as it rotates circumferentially.
[0011] Furthermore, the blocking part includes a guide member extending outward along the axial direction of the limiting groove. The guide member is arranged in an arc shape, and the distance of the radially inner side of the guide member gradually increases as it moves away from the limiting groove.
[0012] Furthermore, the blocking portion also includes a connector disposed on the receiving portion and extending toward the draining member, and fixed relative to the receiving portion and the draining member respectively, to strengthen the connection between the draining member and the receiving portion.
[0013] Furthermore, the drainage mechanism also includes a recovery section for recovering the fluid after it has been drained by the blocking section. The recovery section includes a base plate and side plates disposed on the base plate and extending axially outward. The side plates enclose the base plate to form a cavity for containing the fluid together with the base plate. The fixing mechanism is disposed at the center of the base plate.
[0014] Furthermore, the recovery unit also includes a flow guide disposed on the side plate, the flow guide being configured to allow the fluid moving outward after being guided by the flow guide to accumulate in the cavity.
[0015] Furthermore, the guide is configured as an arc-shaped structure, with its end facing the fixing mechanism.
[0016] Furthermore, the device also includes a drive mechanism configured to be fixed relative to the drainage mechanism to drive the drainage mechanism to rotate circumferentially, thereby causing the fixing mechanism to rotate circumferentially, so that the leak-proof plug located on the fixing mechanism and the pipe to be sealed are connected to or disconnected from each other.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This invention includes a fixing mechanism for securing the leak-proof plug to itself, and a flow-guiding mechanism for blocking fluid and preventing splashing. The fixing mechanism includes a receiving portion for receiving the leak-proof plug, and the flow-guiding mechanism includes a blocking portion surrounding the receiving portion. The radial distance of the inner side of the blocking portion gradually increases in the direction away from the receiving portion, so that after the fluid comes into contact with the blocking portion, it moves away from the receiving portion under the action of the blocking portion. In this way, fluid splashing in all directions is prevented, and fluid splashing onto the operator is also prevented. Attached Figure Description

Detailed Implementation
[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0026] To better understand the purpose, structure, and function of this utility model, the following detailed description of a device for installing a leak-proof plug, in conjunction with the accompanying drawings, is provided.
[0027] For convenience, the direction extending along the pipe to be sealed will be referred to as "axial" or similar term, the direction perpendicular to the "axial" direction will be referred to as "radial" or similar term, and the direction of movement along the "axial" direction toward the pipe to be sealed will be referred to as "axial outward" or similar term.
[0028] like Figure 1 As shown, the leak-proof plug 10 typically includes a connecting rod 101 and a connecting cap 102 disposed on the connecting rod 101. The connecting rod 101 has an external thread along the axial direction, allowing the external thread to connect with the pipe to be sealed (not shown in the figure) to achieve sealing of the pipe. Specifically, the pipe to be sealed has an internal thread along the axial direction, which is configured to engage with the external thread.
[0029] Meanwhile, the cross-section of the connecting cap 102 is designed as a polygon to facilitate connection with the clamping tool (not shown in the figure), thereby facilitating the connection of the driving connecting rod 101 and the pipe to be sealed. It should be noted that the specific structure and connection relationship of the leak-proof plug 10, the pipe to be sealed, and other related components are well-known to those skilled in the art. Therefore, they will not be described in detail here.
[0030] Figure 2 The schematic diagram illustrates the overall structure of the device for installing a leak-proof plug according to the present invention. In such a way... Figure 2 In the illustrated embodiment, the device 100 for installing the leak-proof plug includes a fixing mechanism 1, which is configured to receive the leak-proof plug 10 and be fixed to the leak-proof plug 10.
[0031] At the same time, such as Figure 2 As shown, the device 100 also includes a diversion mechanism 2, which is configured to block fluid splashing circumferentially. Specifically, when the leak-proof plug 10 continuously enters the pipe to be sealed, the leak-proof plug 10 applies an axial inward force to the fluid in the pipe, and as the fluid continues to move along the pipe to be sealed, it applies an axial outward force to the leak-proof plug 10. In this configuration, the fluid will splash to the outside through the gap between the leak-proof plug 10 and the pipe to be sealed.
[0032] In this embodiment, as Figure 2 As shown, the fixing mechanism 1 includes a receiving portion 11 configured to receive a leak-proof plug 10. Meanwhile, the drainage mechanism 2 includes a blocking portion 21 arranged around the receiving portion 11, with the radial distance of the inner side of the blocking portion 21 gradually increasing in a direction away from the receiving portion 11.
[0033] In this way, after the fluid and the blocking part 21 come into contact with each other, the fluid can move away from the receiving part 11 under the action of the blocking part 21, thereby preventing the fluid from splashing in all directions and splashing onto the operator.
[0034] In one embodiment, such as Figure 3 As shown, the receiving portion 11 includes a limiting groove 111 configured to allow it to engage with the leak-proof plug 10 in the circumferential direction. In this embodiment, the limiting groove 111 is provided in a plurality of units and is distributed sequentially along the axial direction.
[0035] In this way, the limiting groove 111 can accommodate leak-proof plugs 10 of different sizes. It should be noted that each limiting groove 111 can be adapted to a leak-proof plug 10 of one size. It should also be noted that the cross-section of the limiting groove 111 is also set as a polygonal structure, allowing it to fit together with the leak-proof plug 10.
[0036] In one embodiment, such as Figure 2 , 3 As shown, the fixing mechanism 1 also includes a fixing part 12, which passes through the receiving part 11 and allows radial movement within the limiting groove 111. In this way, the fixing part 12 can selectively abut against the leak-proof plug 10, thereby selectively and stably positioning the leak-proof plug 10 within the limiting groove 111.
[0037] According to a preferred embodiment of the present invention, such as Figure 2 , 3 As shown, the fixing part 12 includes a threaded hole 121 extending radially through the receiving part 11, and a threaded rod 122 disposed within the threaded hole 121. The threaded rod 122 is configured to allow it to engage with the threaded hole 121.
[0038] In this way, as the threaded rod 122 rotates circumferentially, it can also move radially, thereby causing the threaded rod 122 and the leak-proof plug 10 to abut against each other, or to disengage the threaded rod 122 and the leak-proof plug 10 from each other. This allows for the installation of the leak-proof plug 10 on the fixing mechanism 1 or the removal of the leak-proof plug 10 from the fixing mechanism 1.
[0039] In one embodiment, such as Figure 3 As shown, the blocking part 21 includes a guide member 211 extending axially outward along the limiting groove 111. The guide member 211 is arc-shaped, and the distance from its radially inward side gradually increases with distance from the limiting groove 111. This increases the fluid adhesion capacity on the guide member 211, thereby reducing fluid separation. Furthermore, this arrangement allows the guide member 211 and the limiting groove 111 to jointly form a path guiding fluid movement. This further reduces fluid separation.
[0040] According to a preferred embodiment of the present invention, such as Figure 3As shown, the blocking portion 21 also includes a connecting member 212 disposed on the receiving portion 11 and extending along the drain member 211. In this embodiment, the connecting member 212 is configured to be fixed relative to the receiving portion 11 and the drain member 211, respectively. In this way, a stable connection is achieved between the drain member 211 and the receiving portion 11.
[0041] In this configuration, such as Figure 4 As shown, when the device 100 is needed to perform a leak-stopping operation on the pipeline to be sealed, the leak-proof plug 10 is first placed on one of the limiting grooves 111, and the leak-proof plug 10 and the limiting groove 111 are engaged with each other in the circumferential direction.
[0042] Simultaneously, a force is applied to the threaded rod 122, causing it to rotate within the threaded hole 121. During this process, the threaded rod 122 moves radially closer to the leak-proof plug 10 until the threaded rod 122 and the leak-proof plug 10 come into contact with each other, thereby fixing the leak-proof plug 10 onto the fixing mechanism 1.
[0043] Then, a force is applied to the device 100, causing the blocking part 21 to be fitted onto the pipe to be sealed, allowing the leak-proof plug 10 and the pipe to be sealed to abut against each other. Simultaneously, the device 100 is rotated. During this process, the leak-proof plug 10 will continuously penetrate into the pipe to be sealed.
[0044] Furthermore, during this process, the fluid inside the pipe will splash outwards under the action of the leak-proof plug 10 and move onto the drain member 211. At this time, the drain member 211 will exert a reaction force on the fluid, thereby preventing the fluid from splashing outwards and splashing onto the operator. As the device 100 is continuously rotated, the leak-proof plug 10 will continue to enter the pipe to be sealed until the fluid in the pipe to be sealed no longer flows outwards from its end.
[0045] In one embodiment, such as Figure 2 As shown, the diversion mechanism 2 also includes a recovery section 22, which is used to recover the fluid diverted by the blocking section 21. In this embodiment, the recovery section 22 includes a base plate 221 and side plates 222 disposed on the base plate 221 and extending axially outward. The side plates 222 surround the base plate 221 to form a cavity 223 for containing fluid. Meanwhile, the fixing mechanism 1 is disposed at the center of the base plate 221. It should be noted that the blocking section 2 is located within the cavity 223.
[0046] In addition, such as Figure 2As shown, the recovery unit 22 also includes a flow guide 224 disposed on the side plate 222, the flow guide 224 being configured to allow the fluid moving outward after being guided by the flow guide 211 to be blocked so that the fluid can accumulate in the cavity 223.
[0047] In this way, the fluid moving onto the guide member 211 is able to move into the cavity 223 after being subjected to the reaction force of the guide member 211, and is blocked by the guide member 224 in the cavity 223, so that the fluid can continuously accumulate in the cavity 223. Thus, the fluid splashed out from the pipe to be blocked is recovered through the cavity 223.
[0048] According to a preferred embodiment of the present invention, such as Figure 2 As shown, the flow guide 224 is configured with an arc-shaped structure, with its end facing the fixing mechanism 1. This increases the fluid adhesion capacity on the flow guide 224, thereby reducing fluid separation. It should be noted that the radial distance between the flow guides 224 is greater than that between the pipes to be blocked.
[0049] In one embodiment, such as Figure 2 As shown, the device 100 also includes a drive mechanism 3, which is configured to be fixed relative to the drainage mechanism 2 to provide a fulcrum for driving the device 100. This facilitates the application of force, driving the drainage mechanism 2 to rotate circumferentially, which in turn causes the fixing mechanism 1 to rotate circumferentially, allowing the leak-proof plug 10 on the fixing mechanism 1 and the pipe to be sealed to connect or disconnect from each other. In this embodiment, the drive mechanism 3 includes a plurality of drive arms 31 distributed circumferentially along the drainage mechanism 2. This facilitates the application of force.
[0050] According to a preferred embodiment of the present invention, such as Figure 2 , 3 As shown, a handle 1221 is also provided at the free end of the threaded rod 122. The handle 1221 is used to provide a fulcrum for force application, thereby facilitating the driving of the threaded rod 122 to move along the threaded hole 121.
[0051] The operation of the device for installing the leak-proof plug according to this utility model is as follows.
[0052] like Figure 2 , 4 As shown. First, select a leak-proof plug 10 that matches the size of the pipe to be sealed, and place the leak-proof plug 10 in a limiting groove 111 that matches its size, so that the leak-proof plug 10 and the limiting groove 111 are engaged with each other in the circumferential direction.
[0053] Simultaneously, a force is applied to the handle 1221, causing the handle 1221 to drive the threaded rod 122 to rotate. During this process, the threaded rod 122 moves radially closer to the leak-proof plug 10 until the threaded rod 122 and the leak-proof plug 10 abut against each other, thereby achieving the operation of fixing the leak-proof plug 10 on the fixing mechanism 1.
[0054] Then, a force is applied to the drive arm 31, causing the recovery unit 22 to be fitted onto the pipe to be sealed, allowing the leak-proof plug 10 and the pipe to be sealed to abut against each other. Simultaneously, the device 100 is rotated. During this process, the leak-proof plug 10 will continuously enter the pipe to be sealed.
[0055] Furthermore, during this process, the fluid inside the pipe will splash outwards under the action of the leak-proof plug 10 and move onto the drain member 211. At this time, the drain member 211 will exert a reaction force on the fluid, causing the fluid to move onto the side plate 222 and the guide member 224, and continuously accumulate in the cavity 223.
[0056] Thus, the fluid splashed out from the pipe to be sealed is recovered through the cavity 223. As the device 100 is continuously rotated, the leak-proof plug 10 will continuously enter the pipe to be sealed until the fluid in the pipe to be sealed no longer flows out from its end, thereby achieving the leak-sealing operation.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
