Description

Technical Field

[0001] This invention relates to a pipeline repair device, and more particularly to a double-action positioning pipeline repair airbag device. Background Technology

[0002] In cities, in order to distribute water to every household or to discharge sewage from each household, several pipes are installed and added in each household to connect to the outside world. Therefore, the use of water pipes is particularly widespread and common in cities. In some urban areas, larger pipes are hidden underground. When these pipes are damaged or cracked, it is difficult for maintenance personnel to repair them. In this case, pipe repair procedures are often used for repair.

[0003] Chinese invention patent CN107387938A discloses a pipeline repair robot. Its drive planetary gear set includes a sun gear and multiple evenly distributed planetary gears meshing with the sun gear. A repair motor is installed inside the repair chamber, and its output shaft passes through the repair chamber and connects to a repair fluid tank. Multiple cameras are evenly distributed and connected to the outer wall of the front end of the repair chamber shell. The drive motor and drive planetary gear set are respectively connected to the drive chamber, and the output shaft of the drive motor is connected to the sun gear of the drive planetary gear set. Planetary gear shafts are connected to planetary gears, and both ends of the planetary gear shafts are respectively connected to the repair chamber and the power source chamber, with drive turbines connected to both ends of the planetary gear shafts. Walking frames pass through the shells of the repair chamber and the power source chamber and are connected to the drive turbines. A power battery, power manager, and controller are respectively connected to the power source chamber, and the controller is electrically connected to the power manager, power battery, drive motor, repair motor, cameras, and handheld controller. This invention is highly efficient, has low labor intensity, and good economic benefits.

[0004] The above-described structure provides a pipeline repair device that can be remotely controlled to repair pipelines. However, the above structure requires the pipeline to be cleaned or the inside of the pipeline to be cleaned before the pipeline can be repaired. When some pipelines have cracks, groundwater may seep in when the main valve is closed, causing the above-described device to need to be repaired inside the pipeline with water flow. Therefore, the device is prone to slippage and other phenomena caused by the scouring of water flow. Summary of the Invention

[0026] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0027] like Figures 1 to 9As shown, a double-action positioning pipe repair airbag device includes a first connecting plate 1, a second connecting plate 2, a movable base 3, a transverse moving rod 4, an air cylinder 5, a swing shaft 6, a lifting base 7, a camera assembly 8, and an electrical control component 9. The first connecting plate 1 and the second connecting plate 2 are symmetrically arranged and connected to each other by the air cylinder 5. The movable base 3 is connected to the side of the first connecting plate 1 away from the air cylinder 5. An insertion port is provided on the top of the first connecting plate 1, into which the electrical control component 9 is inserted. The first connecting plate 1 and the second connecting plate 2 are connected to the movable base 3. An airbag 51 is connected between the two connecting plates 2 at their edges. An opening is provided on the top of the second connecting plate 2, into which a camera assembly 8 is inserted. A hollow cylinder 41 is connected to the side of the second connecting plate 2 away from the airbag 5. A horizontal moving rod 4 passes through the hollow cylinder 41. A fixed plate 62 is connected to the end of the horizontal moving rod 4 away from the hollow cylinder 41. The fixed plate 62 is connected to a horizontally arranged swing shaft 6. A vertically arranged lifting seat 7 is provided on one side of the surface of the swing shaft 6. A lifting plate 31 is provided inside the moving seat 3, and a moving mechanism is connected below the lifting plate 31. The housing 35 has a lifting motor 34 located in front of the movable seat 3. A lifting gear is located on one side of the lifting motor 34, meshing with a lifting plate 31 and driving it to move up and down reciprocally. A first electrical contact plate 13 is located at the bottom of the socket of the first connecting plate 1. An electronic control component 9 is inserted into the bottom of the socket, and a contact plate is located at the end that abuts against the first electrical contact plate 13. A battery 92 is embedded within the electronic control component 9. An air cylinder 5 is connected to a filter element 58 at one end of the first connecting plate 1. The filter element 58 is connected to a conduit. Inside the air cylinder 5, and connected to a cavity 55 inside the air cylinder 5, one side of the cavity 55 is connected to the air outlet 56 of the air cylinder 5; one end of the transverse moving rod 4 is connected to the air pump 42 by a conduit, the air pump 42 is located inside the fixed plate 62, the transverse moving rod 4 uses the filter element 42 to move back and forth in one direction along the opening of the hollow cylinder 41; the lifting seat 7 uses the swing shaft 6 to swing back and forth in one direction, the lifting seat 7 has a repair seat 71 and a scraper seat 72 on opposite sides, the repair seat 71 and the scraper seat 72 move up and down along the lifting seat 7 respectively.

[0028] This invention is used for pipeline repair and can automatically travel into the pipeline. A movable seat 3 carries the invention into the pipeline. When it reaches the section of the pipeline that needs repair or has cracks, the first connecting plate 1 and the second connecting plate 2 are positioned on the side of the area requiring repair. Then, through the cooperation of the air cylinder 5 and the filter element 58, the airbag 51 embedded between the first connecting plate 1 and the second connecting plate 2 is inflated, causing the airbag 51 to block the pipeline, thereby sealing the pipeline and intercepting the water flow inside, preventing the water flow from affecting subsequent repair procedures. After the pipeline is sealed, the horizontal moving rod 4 injects gas into the hollow cylinder 41 through the air pump 42 and pushes the horizontal moving rod 41 to align the swing shaft 6 with the area of ​​the pipeline that needs to be repaired. Finally, the repair seat 71 is lifted by the lifting seat 7, and the repair liquid stored in the repair seat 71 is applied to the area of ​​the pipeline with cracks. After the liquid is fully applied, the repair seat 71 is reset, and the scraper seat 72 is lifted. The scraper seat 72 is used to scrape the repair liquid evenly to avoid uneven application. The repair liquid is then scraped and compacted by the scraper seat 72 to achieve a better repair effect.

[0029] The invention features two modes: manual and automatic. In automatic mode, the control unit moves the invention to its destination to repair the area of ​​the pipeline. In manual mode, the invention can be remotely controlled via an external wireless control device, enabling remote repair in areas that are difficult to observe. Furthermore, the invention is equipped with a camera group 8, allowing it to provide a view of the outside world even inside pipelines that are difficult to observe with the naked eye.

[0030] After adopting the above structure, it should be further explained that, in addition to using the airbag 51 to intercept the water flow in the pipeline, the present invention can also expand the airbag 51 in the pipeline and serve as a support and positioning function, so as to avoid slippage during the positioning process using the movable seat 1 and avoid accidents during the repair work.

[0031] The outer surface of the airbag 51 of the present invention is coated with a material that can provide greater friction, such as rubber.

[0032] The movable base 3 has at least two through slots, and each of the two through slots inserts a lifting plate 31. The two lifting plates 31 are arranged vertically. Each of the two lifting plates 31 has an inwardly recessed toothed groove on the side connected to the lifting motor 34. The lifting motor 34 is covered by a protective shell 33, which is fixed to the outside of the protective shell 33 and to the outside of the movable base 3. Below the two lifting plates 31 is a component, in which the movable housing 35 is embedded. The component is located away from the lifting motor 31. A vertical groove is provided on one side of 4, and a strip rib 11 is embedded in the vertical groove. The strip rib 11 is fixed to the outside of the first connecting plate 1. At least two rollers 36 are provided inside the mobile housing 35. The two rollers 36 are respectively fixed to the groove below the mobile housing 35 by uprights. A drive motor 37 is engaged between the two rollers 36. The lifting motor 34 and the drive motor 37 are respectively connected to one end of a spring coil, and are respectively connected to the terminal block 12 inside the first connecting plate 1 by the extension of the spring coil.

[0033] With the above structure, it should be further explained that the movable seat 3 can push the movable housing 35 downward through the lifting motor 34, and let the two rollers 36 inside the movable housing 35 go ​​beyond the edge of the first connecting plate 1, so as to avoid the edge of the first connecting plate 1 from obstructing the back and forth movement of the two rollers 36 of the movable housing 35.

[0034] Two rollers 36 form a group, and at least two groups of rollers 36 are provided inside the mobile chassis 35. This arrangement allows the mobile chassis 35 to move more smoothly.

[0035] In order to prevent the mobile chassis 35 from swaying left and right when it moves up and down through the block, at least two vertical grooves are provided on the edge of the block. These two vertical grooves move up and down through the embedded strip ribs 11, and also limit the left and right sway of the block.

[0036] The roller 36 rolls by engaging with the motor 37. Therefore, the surface of the roller 36 has teeth. The toothed roller 36 can be driven by the motor 37 to move. It can also move against the inner wall of the pipe for a long time. The friction between the roller 36 and the inner wall of the pipe is increased. Furthermore, the teeth of the roller 36 are made of rubber, which can further increase the friction during movement.

[0037] A terminal block 12 is fixed inside the first connecting plate 1. The terminal block 12 is electrically connected to the first electrical contact plate 13 via a conduit. The socket of the first connecting plate 1 is located at the top of the first connecting plate 1, and the socket of the first connecting plate 1 matches the shape of the electrical control component 9. The side of the first connecting plate 1 facing the movable base 3 is the front side, and a socket is provided on the front side of the first connecting plate 1.

[0038] With the above structure, it should be further explained that the electronic control component 9 of the present invention is composed of a circuit board and a battery. The circuit board of the electronic control component 9 is used to connect the electronic control component of the present invention and the battery. After the electronic control component 9 is inserted into the first connecting plate 1, the power supply is connected to the electronic control component of the present invention, and the start and stop of the electronic control component of the present invention are turned on and off through the circuit board of the electronic control component 9.

[0039] The electronic control component 9 has a circuit board 93 embedded inside, which is electrically connected to the power supply 92; the upper end of the electronic control component 9 is provided with a signal transceiver 91, which is connected to the circuit board 93 by a conduit; the power supply board of the electronic control component 9 is electrically connected to the circuit board 93; a slot is provided on one side of the electronic control component 9, which is opposite to the insertion hole opened on the first connecting plate 1, and a limiting block 14 is inserted between the two.

[0040] With the above structure, it should be further explained that the electronic control component 1 of the present invention is inserted into the upper socket of the first connecting plate 1, and makes close contact with the first electrical contact plate 13 through the electrical contact head at the end of the electronic control component 9 to achieve electrical connection. The connection structure of the present invention facilitates the installation and disassembly of the electronic control component 9. The outer side of the electronic control component 9 is in close contact with the inner wall of the socket of the first connecting plate 1, preventing external moisture and dust from contacting the internal electrical contact. When it is necessary to import control data, instructions, maps and other information through an external computer, the electronic control component 9 can be pulled out for input, reducing the overall handling of the present invention. When it is necessary to charge the power supply 92, the electronic control component 9 can also be pulled out to connect to an external power supply separately for electrical connection to achieve charging.

[0041] After the electronic control component 9 is inserted into the socket of the first connecting plate 1, in order to ensure stability, an external limiting block 14 is inserted from the outside of the first connecting plate 1 to the surface of the electronic control component 9 to achieve locking and fixation.

[0042] The transceiver 91 of the present invention is a wireless device for receiving and transmitting signals, such as Wi-Fi. This structure allows the present invention to transmit information from inside the pipe to the outside while it is moving inside the pipe, and it can also receive control commands sent from the outside and control the start and stop of the electronic control components of the present invention to realize wireless control.

[0043] The outer side of the electronic control component 9 of the present invention is a box.

[0044] All components of this invention are circuit board assemblies.

[0045] The air cylinder 5 is equipped with an exhaust motor 52 and an exhaust motor 53. The exhaust motor 52 and the exhaust motor 53 are each connected to the cavity 55 through an air hole. A circuit board 54 is provided on the side of the exhaust motor 52 and the exhaust motor 53 away from the cavity 55, and the exhaust motor 52 and the exhaust motor 53 are electrically connected to the circuit board 54. One end of the circuit board 54 is connected to and extends a conduit to the terminal board 12 in the first connecting plate 1. The other end of the exhaust motor 52 and the exhaust motor 53 are respectively connected to an air pipe, which passes through the first connecting plate 1 and extends to the air hole opened in the first connecting plate 1. The airbag 51 expands or contracts outward through the cooperation of the exhaust motor 52 and the exhaust motor 53. A pressure sensor 57 is provided on the outer edge of the air cylinder 5. The pressure sensor 57 is connected to a conduit, which extends and connects to the circuit board 54, and is electrically connected.

[0046] With the above structure, it should be further explained that outside air is drawn in through the air hole of the first connecting plate 1 by the suction motor 53 and passes through the filter element 58. The filter element 58 can prevent water vapor or dirt in the pipe from being drawn into the airbag 51, which would cause liquid accumulation in the airbag 51, thereby shortening the service life of the airbag 51 and reducing the need for disassembly, drainage and maintenance of the airbag 51. When the suction motor 53 draws outside air into the airbag 51, the airbag 51 is inflated.

[0047] The exhaust motor 52 is used to extract gas from the inflated airbag 51 and draw it to the outside through the pipe, thereby inflating the airbag 51.

[0048] The extracted and discharged gas reaches the air cylinder 5, and is then discharged or extracted into the air bladder 51 through the air hole of the air cylinder 5. This arrangement allows the airflow of the inflated air bladder 51 to be more uniform, and avoids the air bladder 51 from having an uneven surface shape when it inflates, which would cause the air bladder 51 to cause displacement of the invention. When extracting air from the air bladder 51, the air bladder 51 can be adsorbed on the outside of the air cylinder 5 to avoid clogging the air hole, thereby reducing the tension of the air bladder 51 during expansion.

[0049] Furthermore, the air cylinder 5 can also be used to house the exhaust motor 52 and the suction motor 53, preventing the exhaust motor 52 and the suction motor 53 from being exposed and causing damage to the airbag 51.

[0050] The socket above the second connecting plate 2 matches the camera assembly 8; the second connecting plate 2 is provided with a second electrical contact plate 21, the upper end of which passes through the bottom of the socket above the second connecting plate 2 and abuts against the electrical contact end 87 provided at the lower end of the camera assembly 8; the front and rear sides of the second electrical contact plate 21 are respectively connected to conduits and extend to the outside of the second connecting plate 2; one side of the second electrical contact plate 21 is connected to the conduit extending from the circuit board 54 by a conduit, and the other side of the second electrical contact plate 21 is connected to the fixed plate 62 by a conduit; one side of the second connecting plate 2 is fixed to one end of the air cylinder 5, and the other side of the second connecting plate 2 is connected to the end of the hollow cylinder 41.

[0051] With the above structure adopted, it should be further noted that the installation method of the camera group 8 and the control component 9 of the present invention is the same, and will not be repeated here.

[0052] The camera assembly 8 includes: a side plate 81, a rotating column 82, a camera 83, a lighting lamp 84, a guide motor 85, a camera control unit 86, and a socket 88. The socket 88 is inserted from top to bottom into the socket above the second connecting plate 2. A vertical plate 81 is located above the socket 88, and at least two vertical plates 81 are provided. Each side plate 81 contains a guide plate 811. The rotating column 82 is located between two vertical plates 81, and a guide motor 85 is located within the rotating column 82. The guide motor 85 is connected to a gear, which meshes with the teeth on the edge of the guide plate 811. The guide motor 85 is located within the rotating column 82. The upper half of the rotating column 82 is hollow, and a crossbar 821 is inserted through the hollow area. The two ends of the crossbar 821 are fixedly connected between two guide plates 811. The guide motor 85 drives the rotating column 82 to move back and forth along the upper edge of each guide plate 811. The guide motor 85 is connected to the camera control unit 86 by a conduit. The camera 83 and the lighting lamp 84 are located on the outside of the rotating column 82. The camera 83 and the lighting lamp 84 are respectively connected by conduits, which extend and connect to the camera control unit 86. The lower end of the camera control unit 86 is connected to the electrical contact terminal 87 by a conduit.

[0053] With the above structure, it should be further explained that the camera group 8 uses the guide motor 85 to drive the rotating column 82 to adjust the illumination direction of the camera 83 and the lighting lamp 84 along the guide plate 811. When the rotating column 82 rotates, it is limited by the crossbar 821 below. The crossbar 821 presses the bottom of the rotating column 82 against the socket 88, so that the guide motor 85 will not swing along the direction of the guide plate 811 due to the drive of the guide motor 85.

[0054] The camera 83 and the lighting lamp 84 of the present invention are used to provide images of pipes that are difficult to survey, and the lighting lamp 84 illuminates the dim environment inside the pipe. The camera 83 and the lighting lamp 84 are electrically disconnected when the socket 88 of the camera assembly 8 is not inserted into the socket of the second connecting plate 2. The power connection is achieved only after the camera assembly 8 is inserted into the second connecting plate 2. Therefore, when the present invention is operated in a visible area, the camera assembly 8 can be disassembled to reduce the energy consumption of the present invention.

[0055] One end of the transverse moving rod 4 is fixed to one side of the fixed plate 62. An air hole is opened in the transverse moving rod 4. One end of the air hole is connected to the hollow cylinder 41, and the other end of the air hole is connected to the pneumatic motor 42 by a conduit. The air vent of the starting motor 42 is connected to the opening in the fixed plate 62. The transverse moving rod 4 uses the pneumatic motor 42 to move back and forth along the direction of the hollow cylinder 41. The pneumatic motor 42 is fixed in the fixed plate 62, and the fixed plate 62 is equipped with a swing control unit 63.

[0056] With the above structure, it should be further explained that a rubber ring is provided at one end of the transverse moving rod 4 that is inserted into the hollow cylinder 41. The rubber ring causes a certain amount of friction with the inner wall of the hollow cylinder 41. Therefore, when the transverse moving rod 4 injects gas into the hollow cylinder 41, it avoids the transverse moving rod 4 extending too fast and becoming uncontrollable.

[0057] The swing shaft 6 has an opening at its lower part; an inner sleeve shaft 602 that matches the swing shaft 6 is provided inside the swing shaft 6 and is tightly fixed to it. A toothed section is provided below the inner sleeve shaft 602, and a swing motor 611 is meshed and connected below the toothed section, and is meshed with the gear of the swing motor 611; the swing motor 611 is fixed inside the swing seat 61, and the swing seat 61 is connected to one end of the transverse moving rod 4; a lifting control unit 603 is provided inside the swing shaft 6, and a connecting wire hole is provided above the swing shaft 6 and the inner sleeve shaft 602. The lifting control unit 603 extends into the lifting seat 7 through a conduit.

[0058] With the above structure, it should be further explained that the setting of the swing shaft 6 provides the left and right swing of the lifting seat 7, so that the lifting seat 7 drives the repair seat 71 and the scraper seat 72 to apply or scrape the repair area.

[0059] The swing shaft 6 swings left and right by engaging the toothed section of the inner sleeve shaft 602 with the swing motor 611 below. The opening at the bottom of the swing shaft 6 is used to expose the toothed section of the inner sleeve shaft 602. The edge of the opening at the bottom of the swing shaft 6 is attached to the two ends of the toothed section. Therefore, after the swing motor 611 swings to a certain quadrant, the edge of the opening at the bottom of the swing shaft 6, which is opposite to the swing direction, reaches the gear of the swing motor 611, thus limiting the swing.

[0060] The lifting seat 7, repair seat 71, and scraper seat 72 are respectively provided with at least two guide grooves on their respective sides that are in close contact with each other. A limiting groove passes through each of the two guide grooves. The two guide grooves on both sides of the lifting seat 7 are respectively provided with toothed sections. The lower ends of the repair seat 71 and scraper seat 72 are respectively provided with a lifting motor 73. The two lifting motors 73 are respectively engaged with the toothed sections of each guide groove. The top of each lifting motor 73 is provided with a limiting rod. The limiting rod extends across the limiting groove in each guide groove and into the lifting seat 7. The end of the limiting rod inserted into the lifting seat 7 is provided with a protrusion. The width of the protrusion is greater than the width of the limiting groove. Each lifting motor 73 reciprocates along the direction of each guide groove. The repair seat 71 is provided with a placement compartment 71. The repair seat 71 has an opening on the side away from the lifting seat 7 and is connected to the placement chamber 71. The top of the placement chamber 71 is provided with a compression frame 711. The center area of ​​the compression frame 711 has an opening. The compression rod 711 runs through the placement chamber 71 and is fixed to the lifting seat 7. The placement chamber 71 has an outlet at the top. The repair fluid container 75 is placed in the placement chamber 71. The top of the repair fluid container 75 has an opening. The upper end of the repair fluid container 75 touches the bottom of the compression frame 711. The opening at the top of the repair fluid container 75 is inserted into the outlet of the repair seat 71. The scraper seat 72 has an open storage groove 72. The opening is located above the storage groove 72. A scraper blade 721 is provided at the edge of the opening of the scraper seat 72.

[0061] With the above structure, it should be further explained that the guide groove of the lifting seat 7 is used to provide the vertical movement of the lifting motor 73 to avoid left and right swaying, while the limiting groove opened in the guide groove and extending into the lifting seat 7 is used to provide the vertical movement of the cable connecting the lifting motor 73 to avoid the cable being clamped or pulled.

[0062] Furthermore, to prevent the repair seat 71 and the scraper seat 72 from falling outwards during vertical movement, the repair seat 71 and the scraper seat 72 are equipped with a limiting rod inserted into the limiting groove, and a protrusion is provided to reach the rear of the limiting groove, so that the repair seat 71 and the scraper seat 72 do not fall outwards. Therefore, the limiting rod and the protrusion are arranged in a T-shape.

[0063] The repair seat 71 of the present invention squeezes the repair fluid container 75 placed inside, and squeezes the repair fluid in the repair fluid container 75 out along the outlet and applies it to the area of ​​the pipe that needs to be repaired. The lower end of the repair fluid container 75 and the placement chamber 71 of the present invention are provided with a lifting structure. The lifting mechanism is an upward support that moves up and down by an ejector motor. The repair fluid container 75 is squeezed upward by the support and the ejector motor. In addition to limiting and fixing the repair fluid container 75, the upper squeezing frame 711 also forms a clamping structure with the ejector motor, so that the repair fluid in the repair fluid container 75 is squeezed out to the outlet.

[0064] After the repair fluid is applied to the repair seat 71, the surface of the pipe is smoothed by the scraper seat 72. Excess repair fluid is collected and flows into the collection tank 72 through the scraper blade 721, which prevents residual repair fluid from adhering to the inside of the pipe and from solidifying on the inner wall of the pipe, thus reducing the obstruction to the discharge of liquid in the pipe.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
