Technical Field

[0001] The present application relates to the technical field of leak plugging devices, and in particular to a leak plugging device suitable for different breach types. 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 are not only less effective, but the support assembly at the front end of the leak plugger is often not replaceable and only supports the use of tanks with a single type of breach (for example, including size and / or shape). For example, a support assembly of a leak plugger is only suitable for tanks with larger breaches, but not suitable for tanks with smaller breaches. For another example, a support assembly of a leak plugger is only suitable for tanks with square breaches, but not suitable for tanks with round breaches.

[0004] Therefore, the supporting components of the above-mentioned leak plugger are often not replaceable and are limited by the adaptability and processing capability to a single breach type (eg, including size and / or shape), which further affects the use effect of the leak plugger.

[0005] Currently, no effective solution has been proposed to the technical problem that the supporting components of the existing leak pluggers in the above-mentioned prior art are often not replaceable and are limited in adaptability and processing capacity to a single breach type (for example, including size and / or shape), which in turn affects the use effect of the leak plugger. Utility Model Content

[0010] Optionally, the first supporting portion is suitable for a breach with a hole diameter of 5 to 150 mm.

[0011] Optionally, the first supporting portion is provided with a sawtooth structure.

[0012] 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, the first nut is threadedly connected to the support rod, and the first nut abuts against one end of the sleeve; 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.

[0013] Optionally, the tightening assembly further includes: a handle, wherein the two ends of the wrench are respectively provided with a third hollow portion and a fourth hollow portion, and the handle is inserted into the second hollow portion or the third hollow portion.

[0014] 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 other end of the first nut.

[0015] Optionally, the blocking assembly includes: an airbag tray, an airbag, and a connecting assembly abutting against the other end of the sleeve, wherein the airbag tray is sleeved on the support rod and connected to the support rod through the connecting assembly; and the airbag is arranged on the airbag tray.

[0016] Optionally, the sleeve is made of copper.

[0017] The present application provides a leak plugging device suitable for different types of breaches. And the leak plugging device provided by the present application includes a support assembly, wherein the support assembly includes a support member and a support rod.

[0040] Figure 1 It is a front view of a leak plugging device suitable for different breach types according to an embodiment of the present application. Figure 2 It is a side view of a leak plugging device suitable for different breach types according to an embodiment of the present application. Figure 3 1 is a cross-sectional view of a leak stopper suitable for different breach types according to an embodiment of the present application. Figure 1 , Figure 2 and Figure 3 As shown, the present application provides a leak plugging device suitable for different types of breaches, including: a support assembly 10, a sleeve 20, a plugging assembly 30 and a tightening assembly 40, wherein the sleeve 20, the plugging assembly 30 and the tightening assembly 40 are all sleeved on the support assembly 10, and the plugging assembly 30 is located above the sleeve 20, and the tightening assembly 40 is located below the sleeve 20, the support assembly 10 includes: a support member 110, and a support rod 120 with a first hollow portion 121 at one end, wherein the support member 110 includes a first support portion 111 and a second support portion 112, the first support portion 111 is configured to be fixed inside the tank body, and the shape and / or size of the first support portion 111 is adapted to the breach of the tank body; the first support portion 111 is fixedly connected to the second support portion 112, and wherein the outer surface of the second support portion 112 is provided with an external thread, the first hollow portion 121 of the support rod 120 is provided with an internal thread, and the second support portion 112 is threadedly connected to the support rod 120.

[0041] As described in the background technology, the existing leak pluggers are not only less effective, but also the support assembly at the front end of the leak plugger is often not replaceable and only supports the use of tanks with a single type of breach (e.g., including size and / or shape). For example, a support assembly of a leak plugger is only suitable for use with tanks with larger breaches, but not suitable for use with tanks with smaller breaches. For another example, a support assembly of a leak plugger is only suitable for use with tanks with square breaches, but not suitable for use with tanks with round breaches.

[0042] Therefore, the supporting components of the above-mentioned leak plugger are often not replaceable and are limited by the adaptability and processing capability to a single breach type (eg, including size and / or shape), which further affects the use effect of the leak plugger.

[0043] In view of this, the present application provides a leak plugging device suitable for different types of breaches. And the leak plugging device provided in the present application includes a support assembly 10. The support assembly 10 includes a support member 110, and a support rod 120 having a first hollow portion 121 at one end. And wherein, the support member 110 includes a first support portion 111 and a second support portion 112, and the first support portion 111 is fixedly connected to the second support portion 112. The shape and / or size of the first support portion 111 is adapted to the breach of the tank body, and the first support portion 111 can be inserted into the interior of the tank body from the breach of the tank body, thereby being fixed inside the tank body.

[0044] In addition, the outer surface of the second support portion 112 is provided with an external thread, and the first hollow portion 121 of the support rod 120 is provided with an internal thread. The outer surface structure of the second support portion 112 corresponds to the inner surface structure of the first hollow portion 121 of the support rod 120, and the second support portion 112 is connected to the support rod 120 by threads.

[0045] Therefore, referring to the above content, since the second support portion 112 of the support member 110 is detachably connected to the support rod 120, the operator can quickly replace the adapted support member 110 based on the characteristics of the tank body rupture, so that the shape and / or size of the first support portion 111 of the support member 110 is adapted to the shape and / or size of the tank body rupture.

[0046] Table 1 shows the model, size and applicable damage conditions of the support member 110 whose first support portion 111 is a T-shaped structure.

[0047] Table 1

[0048] model Dimensions (L×W×H) Applicable crack size T-60 60×4×10 (5—30)×(45—150) T-40 40×4×10 (5—20)×(30—150) T-20 20×4×10 (5—10)×(15—150)

[0049] As can be seen from Table 1, the support member 110 with the first support portion 111 being a T-shaped structure is suitable for the breach type of the slit type. For example, in the case where the breach of the tank body is a slit type, the operator can use the support member 110 with the first support portion 111 being a T-shaped structure. Thus, the support member 110 of the leak stopper can accurately match the breach of the tank body.

[0050] Table 2 shows the model, size and applicable damage conditions of the support member 110 whose first support portion 111 is an H-shaped structure.

[0051] Table 2

[0052]

[0053]

[0054] As can be seen from Table 2 above, the support member 110 with the first support portion 111 being an H-shaped structure can be suitable for most types of breaches. For another example, when the breach size of the tank body is small (the breach of the tank body is 40 mm), an H-shaped support member 110 with a length of 80 mm, a width of 18.5 mm and a height of 10 mm can be used. Thus, it is determined that the support member 110 of the leak stopper can accurately match the breach of the tank body.

[0055] In addition, it is worth noting that the above Tables 1 and 2 only exemplarily show the model, size and applicable damage conditions of the support member 110 whose first support portion 111 is a T-shaped structure, and the model, size and applicable damage conditions of the support member 110 whose first support portion 111 is an H-shaped structure, and the actual situation is not limited to this.

[0056] Thus, the supporting assembly 10 of the leak stopper can be quickly replaced, and the adaptability and processing capability of the leak stopper for tank body breaches are improved. This solves the technical problem that the existing leak stoppers in the prior art are often not replaceable and are limited in adaptability and processing capability to a single breach type (for example, including size and / or shape), thereby affecting the use effect of the leak stopper.

[0057] Optionally, Figure 4 4 is a front view of the first supporting portion 111 of the T-shaped structure according to the embodiment of the present application. Figure 5 1 is a top view of the first support portion 111 of the T-shaped structure according to an embodiment of the present application. Figure 4 and Figure 5 As shown, the first supporting portion 111 is a T-shaped structure.

[0058] Optionally, Figure 6 4 is a front view of the first support portion 111 of the H-shaped structure according to the embodiment of the present application. Figure 7FIG. 1 is a top view of the first support portion 111 of the H-shaped structure according to an embodiment of the present application. Figure 6 and Figure 7 As shown, the first supporting portion 111 is an H-shaped structure.

[0059] Optionally, the first supporting portion 111 is suitable for a hole with a diameter of 5 to 150 mm.

[0060] Optionally, the first supporting portion 111 is provided with a sawtooth structure.

[0061] Specifically, when the inner surface of the tank body is irregular or slippery, the support assembly of the traditional leak stopper often faces the problem of unstable fixation with the tank body and easy slippage. This not only increases the difficulty of operation for the operator, but may also cause secondary leakage due to loose sealing, thereby increasing safety risks.

[0062] Thus, reference Figure 1 , Figure 3 , Figure 4 as well as Figure 6 As shown, the edge of the first support portion 111 is also provided with a serrated structure, so that when the first support portion 111 is inserted into the interior of the tank body and fixed to the inner surface of the tank body, the contact area and friction between the first support portion 111 and the inner surface of the tank body can be increased, thereby significantly improving the gripping force and stability of the first support portion 111.

[0063] In addition, the first support portion 111 with a serrated structure is not only suitable for smooth inner surfaces of tanks, but can also provide a good fixing effect on inner surfaces of tanks with irregular or concave-convex surfaces, thereby ensuring that the leak stopper can achieve reliable sealing under various working conditions.

[0064] Furthermore, the provision of the first support portion 111 with a sawtooth structure simplifies the operation process, allowing operators to more easily fix the first support portion 111 to the inner surface of the tank body, thereby reducing emergency processing time and improving emergency response efficiency.

[0065] 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, the first nut 420 is threadedly connected to the support rod 120, and the first nut 420 abuts against one end of the sleeve 20; 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.

[0066] Specifically, refer to Figure 3 As shown, the tightening assembly 40 includes a wrench 410 and a first nut 420 .

[0067] 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.

[0068] Thus, when the operator pushes the plugging assembly 30 to abut against the breach of the tank body, the operator further sleeves the wrench 410 on the first nut 420 through the second hollow portion 411 and rotates the wrench 410. Under this action, the first nut 420 pushes the sleeve 20 abutting against it until the sleeve 20 and the plugging assembly 30 are tightly fitted. Furthermore, when the operator has tightened the first nut 420 with the wrench 410, the wrench 410 can be removed from the first nut 420, thereby reducing the overall weight of the leak stopper.

[0069] 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.

[0070] 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.

[0071] Preferably, the first nut 420 is a hexagonal nut.

[0072] Optionally, the tightening assembly 40 further includes a handle 430 , wherein the third hollow portion 412 and the fourth hollow portion 413 are respectively provided at both ends of the wrench 410 , and the handle 430 is inserted into the third hollow portion 412 or the fourth hollow portion 413 .

[0073] Specifically, Figure 8 It is a schematic structural diagram of the tightening assembly 40 according to an embodiment of the present application. Fig. 9 is a top view of the tightening assembly 40 according to an embodiment of the present application. Figure 3 , Figure 8 and Fig. 9As 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 430 can be inserted into the third hollow portion 412 or the fourth hollow portion 413 .

[0074] Since it may be rather strenuous for the operator to directly hold the two ends of the wrench 410 to tighten the first nut 420, 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.

[0075] 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 other end of the first nut 420 .

[0076] Specifically, refer to Figure 3 As shown, 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 other end of the first nut 420 .

[0077] 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 sleeved on 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.

[0078] Optionally, the blocking assembly 30 includes: an airbag tray 310, an airbag 320 and a connecting assembly 330 abutting against the other end of the sleeve 20, wherein the airbag tray 310 is sleeved on the support rod 120 and connected to the support rod 120 through the connecting assembly 330; and the airbag 320 is arranged on the airbag tray 310.

[0079] Specifically, Fig.10 is a top view of the airbag tray 310 according to an embodiment of the present application. Fig.11 is a cross-sectional view of the airbag tray 310 according to an embodiment of the present application. Fig.12 It is a schematic diagram of the structure of the airbag 320 according to the embodiment of the present application. Fig.13 is a cross-sectional view of the airbag 320 according to an embodiment of the present application. Fig.14 is a schematic diagram of a connection assembly 330 according to an embodiment of the present application. Fig.10 , Fig.11 , Fig.12 , Fig.13 as well as Fig.14 As shown, the connecting assembly 330 is sleeved on the support rod 120 and connected to the support rod 120. The airbag tray 310 is connected to the support rod 120 through the connecting assembly 330, and the bottom end of the connecting assembly 330 abuts against the top end of the sleeve 20. The airbag 320 is arranged on the airbag tray 310.

[0080] Thus, the operator uses the tightening assembly 40 and pushes the airbag tray 310 through the sleeve 20 and the connecting assembly 330. The airbag tray 310 drives the airbag 320 to move toward the outer surface of the tank opening, and finally makes the airbag 320 close to the outer surface of the tank opening. Thus, the tank can be sealed and the tank can be prevented from leaking.

[0081] Optionally, the sleeve 20 is made of copper.

[0082] Specifically, since the tank body usually stores inflammable and explosive gases or liquids, when the operator holds the sleeve 20, sparks may be generated between the sleeve 20 and the support rod 120 due to friction or collision, thereby causing a safety accident.

[0083] Thus, reference Figure 1 , Figure 2 and Figure 3 As shown, the present application changes the manufacturing material of the sleeve 20 from conventional metal to copper, and the low friction coefficient and high thermal conductivity of copper can help reduce the friction heat and static electricity accumulation between the sleeve 20 and the support rod 120. Therefore, even if the tank body stores flammable and explosive gas or liquid, the risk of safety accidents can be greatly reduced.
