Description

Technical Field

[0001] This invention relates to the field of pipeline leak sealing technology, and in particular to a leak sealing device and its usage method. Background Technology

[0002] Primary electrical equipment refers to electrical equipment directly used for the production, transformation, transmission, conduction, distribution and use of electrical energy. The seals in the operating equipment will age after long-term use, which will lead to oil and gas leakage. If power is cut off for maintenance, it will take a long time. Therefore, it is necessary to seal the equipment with leakage sealing devices to prevent leakage.

[0003] A leak-stopping structure for oil and gas leakage in primary electrical equipment of a thermal power plant, disclosed in publication number CN219198527U, includes an upper semicircular plate and a lower semicircular plate. A leak-stopping component is provided on the opposite surfaces of the upper and lower semicircular plates. The leak-stopping component consists of a first rubber sealing plate, a second rubber sealing plate, a third rubber sealing plate, a grouting pipe, and a drain pipe. A disassembly component is provided on the surface of the first and second rubber sealing plates. The disassembly component consists of a limiting post and a baffle. An assembly component is provided between the upper and lower semicircular plates.

[0004] The aforementioned document describes a method of filling the first and second slurry storage chambers with anti-leakage adhesive via grouting pipes. This method aims to prevent the first and second rubber sealing plates from aging prematurely due to external rainwater and humid air, thus extending their service life. However, while the method involves injecting anti-leakage adhesive into the slurry storage chambers through grouting pipes, some of the adhesive may seep into the pipeline through cracks during injection, potentially affecting the transport of oil and gas containing impurities.

[0005] Therefore, we propose a leakage sealing device to solve the problems mentioned above. Summary of the Invention

[0006] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a double-claw suction cup for assisting in the installation and fixing of decorative ceramic tiles.

[0007] The technical solution of the present invention is as follows:

[0008] A leakage sealing device includes a lower sleeve, an upper sleeve, and fastening bolts. A connecting block is fixed to one side of the lower sleeve, and an upper sleeve is provided above the lower sleeve. A protrusion is integrally provided on the upper side of the upper sleeve near the connecting block. The protrusion at the end of the upper sleeve is rotatably connected to the connecting block at the end of the lower sleeve via a rotating shaft. Mounting blocks are fixed to the other ends of both the lower and upper sleeves. The two sets of mounting blocks are connected by fastening bolts. Side ring plates are fixed to both ends of both the lower and upper sleeves. Two sets of side ring plates are provided at the ends of both the lower and upper sleeves. A sealing ring is provided between the two sets of side ring plates, and the end of the sealing ring is rotatably connected to an adjusting screw on the surface of the lower and upper sleeves. A sealing and leak-sealing component is bonded inside both the lower and upper sleeves, and a leak-proof component is provided in the middle of the lower and upper sleeves above the sealing and leak-sealing component.

[0009] Preferably, the sealing ring is arranged in a semi-circular shape, and the sealing rings inside the lower sleeve and the upper sleeve form a circular shape. The adjusting screw on the outside of the sealing ring is threadedly connected to the surface of the lower sleeve and the upper sleeve, and four sets of adjusting screws are arranged at equal angles on the lower sleeve and the upper sleeve.

[0010] By adopting the above technical solution, the sealing rings inside the end ring plates of the upper and lower pipe sleeves can be tightly squeezed into the pipe when the upper and lower pipe sleeves are closed by rotating the adjusting screw. This allows the two sets of sealing rings to seal the two ends of the pipe at the leakage point, preventing gas or liquid leakage from the pipe.

[0011] Preferably, the sealing and leak-stopping assembly includes a first airbag, and both the first airbag and the second airbag are bonded to the surfaces of the lower sleeve and the upper sleeve. One end of the first airbag is connected to the second airbag through a connecting tube, and an adhesive tape layer is bonded to the outer side of the first airbag and the second airbag.

[0012] Preferably, six sets of connecting tubes are evenly arranged between the first and second airbags.

[0013] By adopting the above technical solution, the use of the first and second airbags at the left and right ends of the upper and lower pipe sleeves allows for the inflation of both ends of the leaking pipe during use, facilitating the sealing of the inside of the pipe sleeve and improving the anti-leakage effect of the device. The adhesive inside the adhesive tape layer can be squeezed out after the first and second airbags are inflated, allowing the first and second airbags to adhere tightly to the inside of the pipe.

[0014] Preferably, the outer end of the first airbag is provided with an air inlet pipe that penetrates the surfaces of the lower and upper sleeves, and the end of the air inlet pipe is threaded with a plug.

[0015] By adopting the above technical solution, the first and second airbags inside the upper and lower sleeves can be inflated by using the air tube and the plug.

[0016] Preferably, both the first and second airbags are semi-circular arc-shaped, and the first and second airbags above the lower sleeve and the first and second airbags below the upper sleeve form a ring-shaped arrangement.

[0017] By adopting the above technical solution, the use of two sets of semi-circular arc-shaped first and second airbags between the upper and lower sleeves can fill and seal the inside of the sleeve, thereby improving the sealing and leak-stopping effect of the device.

[0018] Preferably, the leakage component includes a rubber pad, glass fiber, and an asphalt layer, with the glass fiber bonded underneath the rubber pad and the asphalt layer poured underneath the glass fiber.

[0019] Preferably, silicone pads are bonded to both ends of the rubber pad.

[0020] The above technical solution can be used in combination with rubber pads, fiberglass and asphalt layers to prevent and seal leaks in pipelines.

[0021] Preferably, the asphalt layer is poured and bonded to the upper surface of the connecting tube, and the silicone pads at both ends of the rubber pad are bonded to the upper surfaces of the first airbag and the second airbag, respectively.

[0022] By adopting the above technical solution, when the connecting tube between the first airbag and the second airbag is inflated, the outward force of the expansion will cause the rubber pad to squeeze the pipe, thereby improving the tightness of the connection between the pipe and the anti-leakage component. At the same time, when the first airbag and the second airbag are inflated, the silicone pads at both ends of the rubber pad can be tightly connected to the pipe, thereby improving the anti-leakage effect of the device.

[0023] A method of using a leakage sealing device includes the following steps:

[0024] S1. Align the anti-leakage components in the middle of the lower and upper sleeves with the leaking points of the pipe, and rotate the upper sleeve so that the lower and upper sleeves can wrap around the pipe. Secure the two with the fastening bolts.

[0025] S2. Next, rotate the adjusting screws at the ends of the lower and upper pipe sleeves to further adjust the sealing between the upper and lower pipe sleeves and the pipe.

[0026] S3. Start the external air pump to inflate the first and second airbags through the air inlet pipe. This will inflate and expand the first and second airbags, which will squeeze the silicone pad and make the silicone pad fit tightly against the pipe, thus sealing the leak at both ends.

[0027] S4. After inflation, the connecting tube will move the asphalt layer upward, so that the rubber pad at the top of the asphalt layer fits tightly against the leak in the pipe.

[0028] The present invention has the following beneficial effects:

[0029] 1. The present invention utilizes the first and second airbags inside the upper and lower sleeves to inflate and seal the upper and lower sleeves. In conjunction with the sealing rings and adjusting screws at both ends of the upper and lower sleeves, the sealing and leak-stopping effects at both ends of the upper and lower sleeves are improved.

[0030] 2. In this invention, when the first and second airbags are inflated, they cause the silicone pad on the anti-leakage assembly to adhere tightly to the surface of the pipe. At the same time, when the connecting tube between the first and second airbags is inflated and collides, it causes the asphalt layer adhered to its surface to move upward as a whole, so that the rubber pad at the upper end of the asphalt layer adheres tightly to the surface of the pipe, thereby improving the anti-leakage effect of the device.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] See Figures 1 to 6 A leakage sealing device includes a lower sleeve 1, an upper sleeve 3, and fastening bolts 7. A connecting block 2 is fixed to one side of the lower sleeve 1, and the upper sleeve 3 is disposed above the lower sleeve 1. A protrusion 4 is integrally provided on the upper side of the upper sleeve 3 near the connecting block 2. The protrusion 4 at the end of the upper sleeve 3 is rotatably connected to the connecting block 2 at the end of the lower sleeve 1 via a rotating shaft 5. Mounting blocks 6 are fixed to the other ends of both the lower sleeve 1 and the upper sleeve 3. The two sets of mounting blocks 6 are connected by fastening bolts 7. The two ends of the lower sleeve 1 and the upper sleeve 3 are... Both are fixed with side ring plates 8, and the side ring plates 8 at the ends of the lower sleeve 1 and the upper sleeve 3 are provided with two sets. A sealing ring 9 is provided between the two sets of side ring plates 8, and the end of the sealing ring 9 is rotatably connected to the adjusting screw 10 on the surface of the lower sleeve 1 and the upper sleeve 3. The sealing ring 9 is set in a semi-circular ring shape, and the sealing ring 9 inside the lower sleeve 1 and the upper sleeve 3 forms a circular ring shape. The adjusting screw 10 on the outside of the sealing ring 9 is threadedly connected to the surface of the lower sleeve 1 and the upper sleeve 3, and four sets of adjusting screw 10 are provided at equal angles on the lower sleeve 1 and the upper sleeve 3.

[0041] By rotating the adjusting screw 10, when the upper sleeve 3 and the lower sleeve 1 are closed, the sealing rings 9 inside the end side ring plates 8 of the upper sleeve 3 and the lower sleeve 1 tightly squeeze the pipe, so that the two sets of sealing rings 9 seal the two ends of the leakage point and prevent gas or liquid from leaking out of the pipe.

[0042] See Figures 1 to 6 Both the lower sleeve 1 and the upper sleeve 3 are internally bonded with sealing and leak-stopping components 11. The sealing and leak-stopping components 11 include a first airbag 1101. The first airbag 1101 and the second airbag 1102 are both bonded to the surfaces of the lower sleeve 1 and the upper sleeve 3. One end of the first airbag 1101 is connected to the second airbag 1102 through a connecting tube 1103. Six sets of connecting tubes 1103 are evenly arranged between the first airbag 1101 and the second airbag 1102. An adhesive tape layer 1106 is bonded to the outer side of the first airbag 1101 and the second airbag 1102.

[0043] The use of the first airbag 1101 and the second airbag 1102 at the left and right ends inside the upper sleeve 3 and the lower sleeve 1 allows for the inflation of air at both ends of the pipe leakage point during use, facilitating the sealing of the inside of the sleeve and improving the anti-leakage effect of the device. The adhesive inside the adhesive tape layer 1106 can be squeezed out after the first airbag 1101 and the second airbag 1102 are inflated, so that the first airbag 1101 and the second airbag 1102 are tightly adhered to the inside of the pipe.

[0044] Furthermore, the outer end of the first airbag 1101 is provided with an air inlet pipe 1104 that penetrates the surfaces of the lower sleeve 1 and the upper sleeve 3, and the end of the air inlet pipe 1104 is threadedly connected with a plug 1105.

[0045] The first airbag 1101 and the second airbag 1102 inside the upper sleeve 3 and the lower sleeve 1 can be inflated by using the air inlet tube 1104 and the plug 1105.

[0046] Furthermore, both the first airbag 1101 and the second airbag 1102 are semi-circular arc-shaped, and the first airbag 1101 and the second airbag 1102 above the lower sleeve 1 and the first airbag 1101 and the second airbag 1102 below the upper sleeve 3 form a ring-shaped arrangement.

[0047] The device can improve its sealing and leak-stopping effect by using two sets of semi-circular arc-shaped first airbags 1101 and second airbags 1102 between the upper sleeve 3 and the lower sleeve 1 to fill and seal the inside of the sleeve.

[0048] Furthermore, a leak-proof component 12 is provided in the middle of the lower sleeve 1 and the upper sleeve 3, located above the sealing and plugging component 11. The leak-proof component 12 includes a rubber pad 1201, a glass fiber 1202 and an asphalt layer 1203. The glass fiber 1202 is bonded to the bottom of the rubber pad 1201, and the asphalt layer 1203 is poured below the glass fiber 1202.

[0049] Furthermore, silicone pads 1204 are bonded to both ends of the rubber pad 1201.

[0050] The rubber pad 1201, glass fiber 1202 and asphalt layer 1203 can be used together to prevent and stop leaks in the pipeline.

[0051] Furthermore, the asphalt layer 1203 is poured and bonded to the upper surface of the connecting tube 1103, and the silicone pads 1204 at both ends of the rubber pad 1201 are respectively bonded to the upper surfaces of the first airbag 1101 and the second airbag 1102.

[0052] When the connecting tube 1103 between the first airbag 1101 and the second airbag 1102 is inflated, the outward force of the expansion will cause the rubber pad 1201 to squeeze the pipe, thereby improving the tightness of the connection between the pipe and the anti-leakage component 12. At the same time, when the first airbag 1101 and the second airbag 1102 are inflated, the silicone pads 1204 at both ends of the rubber pad 1201 can be tightly connected to the pipe, thereby improving the anti-leakage effect of the device.

[0053] A method of using a leakage sealing device includes the following steps:

[0054] S1. Align the anti-leakage component 12 in the middle of the lower sleeve 1 and the upper sleeve 3 with the leakage point of the pipe, and rotate the upper sleeve 3 so that the lower sleeve 1 and the upper sleeve 3 can wrap around the pipe, and fix the two with the fastening bolt 7.

[0055] S2. Next, rotate the adjusting screws 10 at the ends of the lower sleeve 1 and the upper sleeve 3 to further adjust the sealing between the upper sleeve 3 and the lower pipe 1 and the pipe.

[0056] S3. Start the external air pump to inflate through the air inlet pipe 1104, so that the first airbag 1101 and the second airbag 1102 are inflated and expanded, which will squeeze the silicone pad 1204 and thus make the silicone pad 1204 fit tightly with the pipe for air sealing at both ends of the leakage.

[0057] S4. After inflation, the connecting tube 1103 will drive the asphalt layer 1203 to move upward, so that the rubber pad 1201 at the upper end of the asphalt layer 1203 is tightly attached to the leaking part of the pipe.

[0058] Working principle of the invention:

[0059] In this invention, firstly, during use, the anti-leakage component 12 in the middle of the lower sleeve 1 and the upper sleeve 3 is aligned with the leakage point of the pipe, and the upper sleeve 3 is rotated so that the lower sleeve 1 and the upper sleeve 3 wrap around the pipe. Then, the mounting blocks 6 on both of them are connected by fastening bolts 7 so as to fix the lower sleeve 1 and the upper sleeve 3.

[0060] Then rotate the adjusting screws 10 at the ends of the lower sleeve 1 and the upper sleeve 3 so that the sealing ring 9 located at the inner end of the side ring plate 8 can be tightly combined with the surface of the pipe, which can improve the sealing effect between the lower sleeve 1 and the upper sleeve 3 and the surface of the pipe, thereby improving the sealing and leak-proof effect of the device.

[0061] Then, an external air pump is used to inflate the air inlet pipe 1104 on the sealing and plugging assembly 11 so that the first airbag 1101 and the second airbag 1102 inside the lower sleeve 1 and the upper sleeve 3 can inflate and expand inside the lower sleeve 1 and the upper sleeve 3. After the first airbag 1101 and the second airbag 1102 are inflated, they will squeeze the adhesive tape layer 1106 on their outer side, causing the adhesive tape layer 1106 to be squeezed and broken so that the adhesive inside the adhesive tape layer 1106 can tightly adhere the first airbag 1101 and the second airbag 1102 to the pipe, preventing insufficient sealing effect caused by air leakage, so as to inflate and seal both ends of the leakage.

[0062] The anti-leakage component 12 at the pipe leakage point is composed of a rubber pad 1201, a glass fiber 1202, and an asphalt layer 1203. It can prevent the leakage of oil and gas from the pipe. At the same time, the asphalt layer 1203 is located above the connecting tube 1103 between the first airbag 1101 and the second airbag 1102. When inflated, the connecting tube 1103 will also expand, which will cause the connecting tube 1103 to move the asphalt layer 1203 upward, so that the rubber pad 1201 at the upper end of the asphalt layer 1203 can fit more tightly with the pipe leakage point.

[0063] The silicone pads 1204 at both ends of the rubber pad 1201 are located above the first airbag 1101 and the second airbag 1102. When the first airbag 1101 and the second airbag 1102 are inflated, they will also compress the silicone pad 1204, making the silicone pad 1204 fit tightly against the pipe, thereby making the anti-leakage component 12 fit tightly against the pipe sleeve and improving the anti-leakage effect of the device.

[0064] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
