Description

Technical Field

[0001] The present application relates to the technical field of leak pluggers, and in particular to a novel leak plugger. Background Art

[0002] At present, whether it is a gasoline tank, a diesel tank, a gasoline and diesel storage tank, a hazardous chemical transport vehicle, a gas station tank or an oil depot tank, they may all be cracked and leaked due to external factors or service life. When there are damaged holes or gaps on the surface of the above tank (for example, a curved surface or a flat surface), a leak plugger is generally used to prevent the damaged holes or gaps from further leaking.

[0003] However, the existing leak pluggers not only have poor effects, but also the sealing performance of the sealing components used to seal the breach in the tank body is often poor. Specifically, the airbag in the sealing component of the existing leak plugger not only needs to rely on inflation to maintain its shape and function, but the airbag after inflation is usually a hollow circular structure. On the one hand, the operator needs to regularly check and replenish the airbag that relies on inflation to maintain its shape and function to maintain the sealing performance of the airbag. This not only increases the installation time cost for the operator, but also the inflatable airbag is easily damaged in oily and corrosive environments, which may cause safety accidents. On the other hand, since the airbag after inflation is usually a hollow circular structure, there is often a certain gap between the airbag and the tray, which will affect the sealing and adaptability of the leak plugger.

[0004] With regard to the technical problem that the airbag in the sealing component of the existing leak plugger in the above-mentioned prior art not only needs to rely on inflation to maintain its shape and function, but also the airbag after inflation is usually a hollow circular structure, which makes the sealing performance of the sealing component often poor, no effective solution has been proposed so far. Utility Model Content

[0005] The utility model provides a new leak plugger to at least solve the technical problem that the airbag in the sealing component of the existing leak plugger in the prior art not only needs to rely on inflation to maintain its shape and function, but also the airbag after inflation is usually a hollow circular structure, which often makes the sealing performance of the sealing component poor.

[0006] According to one aspect of the present application, a new leak plugger is provided, comprising: a support assembly, a sleeve, a sealing assembly and a tightening assembly, wherein the sleeve, the sealing assembly and the tightening assembly are all sleeved on the support assembly, and the sealing assembly is located above the sleeve, and the tightening assembly is located below the sleeve, the sealing assembly comprises: an annular airbag tray, a hollow annular airbag and a connecting assembly, wherein the airbag tray is sleeved on a support rod and connected to the support rod through the connecting assembly, and wherein a horizontal groove portion is provided on the outer surface of the airbag tray close to one side of the support member, and the airbag comprises a U-shaped top opening downward and a horizontal bottom corresponding to the groove portion; the horizontal bottom of the airbag is provided in the groove portion of the airbag tray, and wherein the airbag is made of nitrile rubber.

[0007] Optionally, the connecting assembly includes: a connecting seat, wherein the connecting seat is sleeved on the support rod and connected to the support rod; and the outer surface of the connecting seat is provided with an external thread, the airbag tray is provided with a first hollow portion, the first hollow portion is provided with an internal thread, and the airbag tray is threadedly connected to the connecting seat.

[0008] Optionally, the connection assembly further includes: an annular sealing ring, wherein the sealing ring is arranged at the abutment portion between the airbag tray and the connection seat, wherein the abutment portion is used to indicate the contact surface between the outer surface of the airbag tray away from the side of the support and the connection seat.

[0009] Optionally, the connection assembly further includes: a first sealing sleeve and a second sealing sleeve, wherein the first sealing sleeve is arranged on the outer surface of the connection seat, wherein the outer surface is close to the support member; and the second sealing sleeve is arranged between the sleeve and the connection seat.

[0010] Optionally, the connection assembly further includes: a first sealing gasket, wherein the first sealing gasket is arranged between the first sealing sleeve and the connection seat.

[0011] Optionally, the connection assembly further includes: a second sealing gasket and a third sealing gasket, wherein the second sealing gasket is arranged between the connection seat and the second sealing sleeve; and the third sealing gasket is arranged between the connection seat and the sleeve.

[0012] Optionally, the first sealing gasket, the second sealing gasket and the third sealing gasket are made of white zinc-plated carbon steel nitrile rubber.

[0013] Optionally, the tightening assembly includes: a wrench and a first nut, wherein the outer surface of the support rod is provided with an external thread, and the first nut is threadedly connected to the support rod; and the wrench is provided with a second hollow portion corresponding to the first nut, and the wrench is sleeved on the first nut through the second hollow portion.

[0014] Optionally, the tightening assembly further includes: a handle, wherein a third hollow portion and a fourth hollow portion are respectively provided at both ends of the wrench, and the handle is inserted into the third hollow portion or the fourth hollow portion.

[0015] Optionally, the tightening assembly further includes: a second nut, wherein the second nut is threadedly connected to the support rod, and the second nut abuts against the first nut.

[0016] The present application provides a novel leak plugger. The leak plugger provided by the present application includes a plugging assembly, wherein the plugging assembly includes an airbag tray, an airbag, and a connecting assembly. The airbag includes a U-shaped top opening downward and a horizontal bottom, and a horizontal groove portion is provided on the outer surface of the airbag tray, and the horizontal bottom of the airbag corresponds to the horizontal groove portion of the airbag tray.

[0017] Since the existing airbags are hollow circular structures and usually need to be inflated to maintain their shape and function, operators need to regularly check and refill the airbags that rely on inflation to maintain their shape and function to maintain the sealing performance of the airbags. This not only increases the installation time cost for operators, but also such inflatable airbags are easily damaged in oily and corrosive environments, which may cause safety accidents.

[0018] As can be seen from the above, compared with the existing hollow circular airbags, since the airbag in the present application includes a horizontal bottom, the airbag tray includes a horizontal groove, and the horizontal bottom of the airbag and the horizontal groove of the airbag tray correspond to each other, the airbag in the present application and the airbag tray can fit tightly, thereby further ensuring the sealing and adaptability of the leak plugger. Furthermore, since the airbag in the present application is made of nitrile rubber, the sealing performance of the airbag can be maintained without relying on inflation during the use of the leak plugger.

[0019] This solves the technical problem in the prior art that the airbag in the sealing component of the existing leak plugger not only needs to rely on inflation to maintain its shape and function, but also the airbag after inflation is usually a hollow circular structure, which often makes the sealing performance of the sealing component poor.

Figure 2 It is a side view of the new leak plugging device according to the embodiment of the present application. Figure 3 It is a cross-sectional view of the new leak plugging device described in the embodiment of the present application. Figure 4 is a top view of the airbag tray 310 according to an embodiment of the present application. Figure 5 is a cross-sectional view of the airbag tray 310 according to an embodiment of the present application. Figure 6 It is a schematic diagram of the structure of the airbag 320 according to the embodiment of the present application. Figure 7 is a cross-sectional view of the airbag 320 according to an embodiment of the present application. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6As shown, a new leak stopper includes: a support component 10, a sleeve 20, a sealing component 30 and a tightening component 40, wherein the sleeve 20, the sealing component 30 and the tightening component 40 are all sleeved on the support component 10, and the sealing component 30 is located above the sleeve 20, and the tightening component 40 is located below the sleeve 20, the sealing component 30 includes: an annular airbag tray 310, a hollow annular airbag 320 and a connecting component 330, wherein the airbag tray 310 is sleeved on the support rod 120 and connected to the support rod 120 through the connecting component 330, and wherein the outer surface of the airbag tray 310 close to one side of the support member 110 is provided with a horizontal groove portion 311, the airbag 320 includes a U-shaped top 321 opening downward and a horizontal bottom 322 corresponding to the groove portion 311; the horizontal bottom 322 of the airbag 320 is provided in the groove portion 311 of the airbag tray 310, and wherein the material of the airbag 320 is nitrile rubber.

[0037] As described in the background technology, the existing leak pluggers not only have poor effects, but also the sealing performance of the sealing components used to seal the breach in the tank body is often poor. Specifically, the airbag in the sealing component of the existing leak plugger not only needs to rely on inflation to maintain its shape and function, but the airbag after inflation is usually a hollow circular structure. On the one hand, the operator needs to regularly check and replenish the airbag that relies on inflation to maintain its shape and function to maintain the sealing performance of the airbag. This not only increases the installation time cost for the operator, but also the inflatable airbag is easily damaged in oily and corrosive environments, which may cause safety accidents. On the other hand, since the airbag after inflation is usually a hollow circular structure, there is often a certain gap between the airbag and the tray, which will affect the sealing and adaptability of the leak plugger.

[0038] In view of this, the present application provides a new type of leak plugger. And the leak plugger provided by the present application includes a plugging assembly 30. The plugging assembly 30 includes an annular airbag tray 310, a hollow annular airbag 320 and a connecting assembly 330. Among them, the airbag tray 310 is sleeved on the support rod 120 and connected to the support rod 120 through the connecting assembly 330. And among them, the outer surface of the airbag tray 310 is provided with a horizontal groove portion 311, and the airbag 320 includes a U-shaped top 321 opening downward and a horizontal bottom 322, and the horizontal groove portion 311 of the airbag tray 310 and the horizontal bottom 322 of the airbag 320 correspond to each other in area and size.

[0039] Therefore, when installing the leak stopper, the operator can push the entire plugging assembly 30 downward, so that the plugging assembly 30 contacts the sleeve 20 , and fix the plugging assembly 30 on the support rod 120 .

[0040] Unlike the prior art, since the existing airbag is a hollow circular structure, the groove of the existing airbag tray is a semicircular groove corresponding to the circular structure, and in the actual manufacturing process, the semicircular groove and the airbag cannot be well adapted. For example, in the actual manufacturing process, the semicircular groove of the airbag tray is usually not very flat, and the surface is uneven, so when the operator places the hollow circular airbag in the semicircular groove, there is usually a certain gap between the airbag and the semicircular groove of the airbag tray, which affects the sealing and adaptability of the leak stopper.

[0041] Furthermore, since the airbag 320 in the present application includes a horizontal bottom 322, the airbag tray 310 includes a horizontal groove portion 311, and the horizontal bottom 322 of the airbag 320 and the horizontal groove portion 311 of the airbag tray 310 correspond to each other, the airbag 320 in the present application and the airbag tray 310 can fit tightly, thereby further ensuring the sealing and adaptability of the leak stopper.

[0042] In addition, since the existing airbags are hollow circular structures and usually need to be inflated to maintain their shape and function, operators need to regularly check and replenish the airbags that rely on inflation to maintain their shape and function to maintain the sealing performance of the airbags. This not only increases the installation time cost for operators, but also such inflatable airbags are easily damaged in oily and corrosive environments, which may cause safety accidents.

[0043] Different from the prior art, the airbag 320 in the present application is made of nitrile rubber, so when using the leak stopper, the sealing performance of the airbag 320 can be maintained without relying on inflation. Even if the leak stopper is in an oily or corrosive environment, the airbag 320 will not be damaged, thereby avoiding safety accidents.

[0044] Thus, the technical problem existing in the prior art that the airbag in the sealing assembly of the existing leak plugger not only needs to rely on inflation to maintain its shape and function, but also the airbag after inflation is usually a hollow circular structure, so that the sealing performance of the sealing assembly is often poor is solved.

[0045] Optionally, the connecting assembly 330 includes: a connecting seat 331, wherein the connecting seat 331 is sleeved on the support rod 120 and connected to the support rod 120; and the outer surface of the connecting seat 331 is provided with an external thread, the airbag tray 310 is provided with a first hollow portion 312, the first hollow portion 312 is provided with an internal thread, and the airbag tray 310 is threadedly connected to the connecting seat 331.

[0046] Specifically, Figure 8 3 is a partial schematic diagram of the connection assembly 330 according to an embodiment of the present application. Figure 1 , Figure 2 , Figure 3 as well as Figure 8 As shown, the connection assembly 330 includes a connection seat 331. The connection seat is sleeved on the support rod 120 and connected to the support rod 120. In addition, the outer surface of the connection seat 331 is provided with an external thread, and the airbag tray 310 is provided with a first hollow portion 312, and the first hollow portion 312 is provided with an internal thread. The airbag tray 310 is sleeved on the connection seat 331 and is connected to the connection seat 331 through threads.

[0047] Optionally, the connecting assembly 330 also includes: an annular sealing ring 332, wherein the sealing ring 332 is arranged on the abutment portion 313 between the airbag tray 310 and the connecting seat 331, wherein the abutment portion 313 is used to indicate the contact surface between the outer surface of the airbag tray 310 away from the side of the support member 110 and the connecting seat 331.

[0048] Specifically, refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 8 As shown, when the airbag tray 310 is connected to the connection seat 331 by threads, there may still be a certain gap between the contact surfaces of the airbag tray 310 and the connection seat 331, which may affect the sealing of the leak stopper. In order to prevent the above situation from happening, the present application sets an annular sealing ring 332 at the abutment portion 313 between the airbag tray 310 and the connection seat 331. This can further prevent gas or liquid leakage and ensure the sealing of the leak stopper.

[0049] Optionally, the connection assembly 330 further includes: a first sealing sleeve 333 and a second sealing sleeve 334 , wherein the first sealing sleeve 333 is disposed on an outer surface 3311 of the connection seat 331 , wherein the outer surface 3311 is close to the support member 110 ; and the second sealing sleeve 334 is disposed between the sleeve 20 and the connection seat 331 .

[0050] Specifically, refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 8 As shown, the connection assembly 330 also includes a first sealing sleeve 333. The first sealing sleeve 333 is arranged in the connection seat 331 close to the outer surface 3311 of the support member 310, and forms a stable sealing structure through a pressing operation, thereby ensuring that gas or liquid will not leak from the thread gap between the connection seat 331 and the support rod 120, thereby further ensuring the sealing of the leak stopper.

[0051] In addition, the connecting assembly 330 also includes a second sealing sleeve 334. The second sealing sleeve 334 is arranged between the sleeve 20 and the connecting seat 331, and forms a stable sealing structure through a pressing operation, thereby ensuring that gas or liquid will not leak from the thread gap between the connecting seat 331 and the support rod 120, thereby further ensuring the sealing of the leak stopper.

[0052] The first sealing sleeve 333 and the second sealing sleeve 334 are made of copper.

[0053] Optionally, the connection assembly 330 further includes: a first sealing gasket 335 , wherein the first sealing gasket 335 is disposed between the first sealing sleeve 333 and the connection seat 331 .

[0054] Specifically, refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 8 As shown, the present application further considers that when the first sealing sleeve 333 is disposed on the outer surface 3311 of the connection seat 331, there may be a certain gap between the first sealing sleeve 333 and the outer surface 3311 of the connection seat 331, so a first sealing gasket 335 is further disposed at the contact portion between the first sealing sleeve 333 and the connection seat 331. This ensures that gas or liquid will not leak from the thread gap between the connection seat 331 and the support rod 113.

[0055] Optionally, the connection assembly 330 further includes: a second sealing gasket 336 and a third sealing gasket 337 , wherein the second sealing gasket 336 is disposed between the connection seat 331 and the second sealing sleeve 334 ; and the third sealing gasket 337 is disposed between the connection seat 331 and the sleeve 20 .

[0056] Specifically, refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 8 As shown, in order to further ensure that gas or liquid does not leak from the thread gap between the connection seat 331 and the support rod 112, the present application further provides a second sealing gasket 336 between the connection seat 331 and the second sealing sleeve 334, and a third sealing gasket 337 between the connection seat 331 and the sleeve 20. Thus, it is ensured that gas or liquid does not leak from the thread gap between the connection seat 331 and the support rod 113.

[0057] Further optionally, the material of the sealing gasket 335 is white zinc-plated carbon steel nitrile rubber. Among them, the first sealing gasket 335, the second sealing gasket 336 and the third sealing gasket 337 can be self-centering composite gaskets, and the material of the first sealing gasket 335, the second sealing gasket 336 and the third sealing gasket 337 is white zinc-plated carbon steel nitrile rubber. Therefore, the first sealing sleeve 333 is used in conjunction with the first sealing gasket 335 to significantly improve the sealing performance of the leak stopper; the second sealing sleeve 334 is used in conjunction with the second sealing gasket 336 and the third sealing gasket 337 to significantly improve the sealing performance of the leak stopper.

[0058] Optionally, the tightening assembly 40 includes: a wrench 410 and a first nut 420, wherein the outer surface of the support rod 120 is provided with an external thread, and the first nut 420 is threadedly connected to the support rod 120; and the wrench 410 is provided with a second hollow portion 411 corresponding to the first nut 420, and the wrench 410 is sleeved on the first nut 420 through the second hollow portion 411.

[0059] Specifically, Fig. 9 It is a schematic structural diagram of the tightening assembly 40 according to an embodiment of the present application. Fig.10 is a top view of the tightening assembly 40 according to an embodiment of the present application. Figure 3 , Fig. 9 and Fig.10 As shown, the tightening assembly 40 includes a wrench 410 and a first nut 420. The outer surface of the support rod 120 is provided with an external thread, the first nut 420 is threadedly connected to the support rod 120, and one end of the first nut 420 abuts against the sleeve 20. The wrench 410 is provided with a second hollow portion 411 corresponding to the first nut 420, the structure of the second hollow portion 411 corresponds to the outer surface structure of the first nut 420, and the wrench 410 is sleeved on the outer surface of the first nut 420 through the second hollow portion 411.

[0060] Thus, when the operator needs to rotate the tightening assembly 40 to push the plugging assembly 30 to fit closely to the outer surface of the tank body through the sleeve 20, the wrench 410 can be sleeved on the first nut 420 through the second hollow portion 411, and the wrench 410 can be rotated to tighten the first nut 420 and make the plugging assembly 30 fit closely to the outer surface of the tank body. Furthermore, when the operator uses the wrench 410 to tighten the first nut 420, the wrench 410 can be removed from the first nut 420, thereby reducing the overall weight of the leak stopper.

[0061] It is worth noting that since the traditional tightening assembly is laborious and time-consuming to install during the tank breach plugging operation, and since the traditional tightening assembly is an integrated structure and cannot be disassembled, the overall weight of the plug may increase after the plugging is completed, thereby affecting the stability of the plug. However, since the present application changes the traditional tightening assembly into a detachable rocker arm structure (i.e., the wrench 410 and the first nut 420 are detachably connected), the operator can install the plug more labor-saving and quickly.

[0062] In addition, after the plugging of the leak stopper is completed, the operator can remove the wrench 410 from the first nut 420 to ensure the stability of the leak stopper.

[0063] Preferably, the first nut 420 is a hexagonal nut.

[0064] Optionally, the tightening assembly 40 further includes a handle 430 , wherein a third hollow portion 412 and a fourth hollow portion 413 are respectively provided at both ends of the wrench 410 , and the handle 410 is inserted into the third hollow portion 412 or the fourth hollow portion 413 .

[0065] Specifically, refer to Figure 3 , Fig. 9 and Fig.10 As shown, the tightening assembly 40 further includes a handle 430 . A third hollow portion 412 and a fourth hollow portion 413 are respectively provided at both ends of the wrench 410 , so that the handle 410 can be inserted into the third hollow portion 412 or the fourth hollow portion 413 .

[0066] Since it may be rather strenuous for the operator to tighten the first nut 420 by holding the two ends of the wrench 410, a third hollow portion 412 and a fourth hollow portion 413 are also provided at both ends of the wrench 410 in the present application, so that the operator can insert the handle 430 into the third hollow portion 412 or the fourth hollow portion 413 and rotate the handle 430, thereby facilitating the operator to tighten the first nut 420 and improving the operator's work efficiency.

[0067] Optionally, the tightening assembly 40 further includes: a second nut 440 , wherein the second nut 440 is threadedly connected to the support rod 120 , and the second nut 440 abuts against the first nut 420 .

[0068] Specifically, refer to Figure 3 As shown, the tightening assembly 40 further includes a second nut 440 , wherein the second nut 420 is threadedly connected to the support rod 120 , and the second nut 440 abuts against the first nut 420 .

[0069] Thus, when the operator tightens the first nut 420 with the wrench 410 and the sealing assembly 30 is close to the outer surface of the tank body, the wrench 410 can be removed from the first nut 420, and the second nut 440 can be threadedly connected to the support rod 120, so that the top end of the second nut 440 is further abutted against the bottom end of the first nut 420, thereby preventing the first nut 420 from loosening, thereby ensuring that the sealing assembly 30 can seal the breach in the tank body.

[0070] Preferably, the second nut 440 is a butterfly nut.
