Description

Technical Field

[0001] The invention relates to the technical field of underground pipe network leakage rapid repair, and in particular to a novel underground pipe network leakage rapid repair device and a use method thereof. Background Art

[0002] Municipal pipe network repair equipment is generally large-volume equipment. When the pipe is seriously damaged, the repair tape is spirally laid from the inside of the pipe. After the repair tape hardens, a new channel is formed on the inner wall of the damaged pipe. The entire pipe is repaired by reducing the diameter of the pipe network. When the pipe is not seriously damaged but needs to be repaired urgently, using large equipment to repair the entire pipe not only wastes materials, but the equipment is large and inconvenient to use.

[0003] A portable municipal pipe network damage repair device with publication number CN221196556U comprises a shell, a side end of the shell is provided with an internal threaded sleeve, the internal threaded sleeve is connected with a center rod, a repair tape is provided on the outer side of the center rod, a fixed plate is fixed to the end of the center rod, a moving mechanism is provided at the lower end of the fixed plate and the shell, a rotating ring is rotatably provided on the outer side of the internal threaded sleeve, a first electric push rod is fixed on the rotating ring, a pressure rod is fixed on the piston rod end of the first electric push rod, a pressure roller is rotatably provided on the outer side of the pressure rod, a fixing mechanism is provided on the pressure roller, and a battery and a control box are installed inside the shell; the portable municipal pipe network damage repair device can lay the repair tape in a spiral shape on the inner wall of the pipe, can realize small-scale repair, reduce the waste of repair materials, and the equipment is small in size and convenient to call.

[0004] However, due to the different forms and dominant factors of pipeline leakage, most traditional temporary pipeline repair devices have problems such as low accuracy and poor repair effect, and most equipment is difficult to quickly control the leakage of water supply pipelines. For urban pipelines that are deeply buried, have high water supply demand, and have long maintenance cycles, a new underground pipeline leakage rapid repair device and use method are now needed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a novel underground pipe network leakage rapid repair device and a use method.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A novel underground pipe network leakage quick repair device comprises a pipe, an internal metal ball is arranged in the pipe, a compressed air bag is arranged on the internal metal ball, a waterproof rubber is sleeved on the compressed air bag, a fluff layer is arranged on the outer side of the waterproof rubber, a plurality of grooves are arranged on the waterproof rubber and the fluff layer, and the grooves are filled with a layer of HBPA super glue;

[0008] A stainless steel metal card shell is arranged on the outer side of the fluff layer.

[0009] Compared with the prior art, the present application inflates the airbag in the middle part to stick the water-stop rubber coated with underwater adhesive on the outer layer to the inside of the pipe to form a ring-shaped body, thereby achieving the function of quickly repairing leaking pipes without affecting the water supply of the pipe; HBPA underwater adhesive is used. When the material comes into contact with water, the hydrophobic chains will quickly self-aggregate to form a coacervate layer, displacing water molecules to the adhesion surface, causing an increase in the exposure of catechol groups, and rapidly enhancing the adhesion of various materials from low surface energy to high energy, thereby ensuring the sealing effect and not producing harmful substances.

[0010] Preferably, the stainless steel metal casing comprises a plurality of single arc-shaped pieces, the plurality of single arc-shaped pieces form a spherical structure, and a splittable structure is formed between two adjacent single arc-shaped pieces.

[0011] Furthermore, in actual production and preparation, a single arc-shaped sheet can adopt an arc-shaped hexagonal structure or an arc-shaped circular structure to effectively form the outermost shell. Multiple single arc-shaped sheets can form a spherical structure, which is convenient for rolling. When in use, the stainless steel metal card shell can be placed in the pipeline and can be rolled in the pipeline, which can quickly

[0012] Preferably, a cushion layer is provided between the stainless steel metal casing and the fluff layer, and the cushion layer is made of an impermeable and easily breakable material.

[0013] Furthermore, in actual use, the compressed air bag will expand due to inflation, which will quickly cause the water-stop rubber to break through the lining layer, and at the same time it can also resist the stainless steel metal shell, so that the multiple single-piece arc-shaped pieces on the stainless steel metal shell are quickly separated, making it easier for the water-stop rubber to resist the inner wall of the pipe.

[0014] Preferably, an electronic controller, a gas generator and a delivery pipe are installed in the stainless steel metal casing, a combustion chamber, a filter and a cooler are provided in the gas generator, the electronic controller is connected to the combustion chamber, the delivery pipe is connected to the compressed air bag, and the delivery pipe is connected to the cooler.

[0015] Furthermore, at a known leakage point, a signal can be remotely controlled to the electronic controller in the internal metal ball. After receiving the signal, the electronic controller compares it with the original stored signal. If the conditions for deploying the compressed airbag are met, the drive circuit sends a start signal to the gas generator in the airbag assembly. After receiving the signal, the gas generator ignites the gas generator to generate a large amount of gas, which enters the compressed airbag after being filtered and cooled, allowing the compressed airbag to break through the liner layer in a very short time and deploy rapidly, allowing the external water-stopping material to fully fit the inner wall of the pipe.

[0016] Preferably, the compression airbag and the water-stop rubber both adopt a tubular structure.

[0017] Furthermore, the compressed air bag and the water-stop rubber can be effectively adapted to the pipe structure, so that the water-stop rubber and the inner wall of the pipe can be contacted faster and better.

[0018] Preferably, the groove is U-shaped, and the opening end of the groove is in a closed state.

[0019] Furthermore, by setting the groove, a layer of HBPA super glue can be effectively added into the groove, and the opening of the groove can be controlled by compressing the airbag, so that the HBPA super glue layer can be in contact with the inner wall of the pipe.

[0020] The beneficial effects of the present invention are:

[0021] 1. This device is controlled by remote control and moves with the water flow inside the pipeline. It can quickly control and repair leaks at known leakage points. It has the characteristics of high precision and rapid action;

[0022] 2. The underwater adhesive on the outside of the water-stop rubber is HBP adhesive (HBPA), which has a high degree of adhesion in water and can be used for medical hemostasis, so it will not pollute the water in the pipe and is harmless to the human body;

[0023] 3. Nowadays, pipeline leakage has various forms. The material of this device has good adhesion, can adapt to various leakage conditions, and has a high degree of safety;

[0024] 4. This device is used in the positive water supply pipeline and moves with the water flow in the pipeline without affecting the water supply in the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-7 A novel underground pipe network leakage rapid repair device comprises a pipe 8, an internal metal ball 2 is arranged in the pipe 8, a compressed air bag 3 is arranged on the internal metal ball 2, a water-stop rubber 4 is sleeved on the compressed air bag 3, a fluff layer 9 is arranged on the outside of the water-stop rubber 4, a plurality of grooves 6 are arranged on the water-stop rubber 4 and the fluff layer 9, and the grooves 6 are filled with a HBPA super glue layer 5; a stainless steel metal card shell 1 is arranged on the outside of the fluff layer 9; the compressed air bag 3 breaks through the cushion layer 7 in a very short time, and makes the plurality of single-piece arc-shaped sheets 101 in the stainless steel metal card shell 1 quickly separate, so that the external water-stop material fully fits with the inner wall of the pipe 8; when the compressed air bag 3 makes the water-stop rubber 4 expand, so that the groove 6 is unfolded, the HBPA super glue layer 5 in the groove 6 can quickly contact with the inner wall of the pipe 8, so as to achieve sealing operation and effectively repair the gap of the pipe 8.

[0035] Reference Figure 1 , 3 The stainless steel metal card shell 1 includes a plurality of single-piece arc-shaped pieces 101, and the plurality of single-piece arc-shaped pieces 101 form a spherical structure. There is a splittable structure between two adjacent single-piece arc-shaped pieces 101. Through the splittable structure between two adjacent single-piece arc-shaped pieces 101, when the compressed air bag 3 therein is expanded, the two adjacent single-piece arc-shaped pieces 101 can be quickly separated, and the single-piece arc-shaped pieces 101 can be quickly detached.

[0036] Reference Figure 1-4A cushioning layer 7 is provided between the stainless steel metal card shell 1 and the fluff layer 9. The cushioning layer 7 is made of impermeable and easily breakable material. When the compressed airbag 3 expands, the water-stop rubber 4 will quickly touch the cushioning layer 7, which can effectively destroy the cushioning layer 7, making it easier for the water-stop rubber 4 to contact the inner wall of the pipe 8. The water-stop rubber 4 is stretched open, which can completely stretch the groove 6, so that the HBPA super glue layer 5 can contact the inner wall of the pipe 8.

[0037] Reference Figure 2 , 7 An electronic controller, a gas generator and a delivery pipe are installed in the stainless steel metal card shell 1. A combustion chamber, a filter and a cooler are arranged in the gas generator. The electronic controller is connected to the combustion chamber, the delivery pipe is connected to the compressed air bag 3, and the delivery pipe is connected to the cooler. At a known leakage point, a signal can be remotely controlled to send a signal to the electronic controller in the internal metal ball 2. After receiving the signal, the electronic controller compares it with its original stored signal. If the condition for the compressed air bag 3 to be deployed is met, the drive circuit sends a start signal to the gas generator in the air bag assembly. After receiving the signal, the gas generator ignites the gas generating agent to generate a large amount of gas, which enters the compressed air bag 3 after being filtered and cooled, so that the compressed air bag 3 breaks through the lining layer 7 in a very short time and is rapidly deployed, so that the external water-stopping material is fully fitted with the inner wall of the pipe 8.

[0038] Reference Figure 2 , 7 The compressed air bag 3 and the water-stop rubber 4 both adopt a tubular structure, which can make the compressed air bag 3, the water-stop rubber 4 and the pipe 8 have the same shape, and can quickly make the water-stop rubber 4 and the pipe 8 better contact and effectively perform contact sealing.

[0039] Reference Figure 4 The groove 6 is U-shaped, and the open end of the groove 6 is in a closed state. During actual production and preparation, the HBPA super glue layer 5 can be stored through the closed state of the open end of the groove 6, and during actual use, the HBPA super glue layer 5 can be combined with the inner wall of the pipe. When the material comes into contact with water, the hydrophobic chains will quickly self-aggregate to form a coacervate layer, displacing water molecules to the adhesion surface, causing an increase in the exposure of the catechol groups, and quickly enhancing the adhesion of various materials from low surface energy to high energy. HBPA super glue can bond different materials with different characteristics and is suitable for pipes of different materials.

[0040] In the present invention, the device is a spherical body, the center of the sphere is a compressed airbag 3 controlled by an electronic controller, the outside of the compressed airbag 3 is a water-stop rubber 4 wrapped with an HBPA super glue layer 5, and the stainless steel metal card shell 1 is a football-shaped splittable material, which is convenient for the internal compressed airbag 3 to be ejected; there is a gap between the stainless steel metal card shell 1 and the internal water-stop rubber 4, and at the same time, there is a groove 6 on the surface of the unexpanded water-stop rubber 4, and a fluff layer 9 is attached to the inner surface of the groove 6, and the internal hollow is filled with the HBPA super glue layer 5. Because the fluff tightly absorbs the HBPA super glue, it can be ensured that the HBPA super glue is not washed away by the water flow when the water-stop rubber 4 is expanded;

[0041] At a known leakage point, a signal can be remotely controlled to send a signal to the electronic controller in the internal metal ball 2. After receiving the signal, the electronic controller compares it with the original stored signal. If the conditions for the compressed airbag 3 to be deployed are met, the drive circuit sends a start signal to the gas generator in the airbag assembly. After receiving the signal, the gas generator ignites the gas generating agent to generate a large amount of gas, which enters the compressed airbag 3 after being filtered and cooled, so that the compressed airbag 3 breaks through the cushion layer 7 in a very short time and quickly deploys, so that the external water-stopping material fully fits with the inner wall of the pipe 8, so as to achieve the purpose of instantly repairing the leakage of the pipe 8; compared with traditional leak repairing technology, the device has higher accuracy and fast leak repairing speed, and can remedy the pipe 8. For a large crack leaking pipe 8, the device can temporarily stop the water, reduce the risk of the pipe 8 crack continuing to expand and causing the pipe 8 to burst, and wait for the construction and maintenance to replace the pipe 8 and recycle it; for a small crack pipe 8, the device can effectively solve the leakage problem, and the material is safe and reliable, has no pollution to water, and can be used permanently;

[0042] Compared with dry environment, it is much more difficult to achieve strong interfacial adhesion underwater; this is because in water, a hydration layer will form on the surface of most materials, which will hinder the adhesive from forming an effective interaction force with the material surface. The HBPA super glue layer 5 is used on the outside of the water-stop rubber 4 of this design. When the material comes into contact with water, the hydrophobic chains will quickly self-aggregate to form a coacervate layer, displacing water molecules to the adhesion surface, causing an increase in the exposure of catechol groups, and rapidly enhancing the adhesion of various materials from low surface energy to high energy. HBPA super glue can bond different materials with different characteristics, and is applicable to pipes of different materials, and will not produce harmful substances and is safe and harmless to the human body.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
