Description

Technical Field

[0001] This utility model relates to the field of sealing robot technology, and more specifically, to a prefabricated quick-release and quick-installation pipeline sealing robot. Background Technology

[0002] A sealing robot is an intelligent mechanical device specifically designed to seal leaks in pipelines. It can automatically locate the leak inside or outside the pipeline and then seal the leak using a specific sealing device to prevent further leakage of liquids, gases, or other media. This robot combines technologies from multiple disciplines, including mechanical engineering, automation control, and materials science, providing an efficient and safe solution for pipeline maintenance.

[0003] Existing equipment for sealing pipeline leaks is inefficient and has poor sealing effect. Too many impurities inside the pipeline affect the sealing effect. Furthermore, some sealing devices cannot be folded or stored, taking up a lot of space when moving and transporting them, making them inconvenient to store and fold.

[0004] Therefore, a modular, quick-release, and quick-installation pipe sealing robot is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an assembly-type quick-release and quick-installation pipe plugging robot to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated quick-release and quick-installation pipe sealing robot, comprising a main shaft, one end of which is connected to an end plate, a sealing rubber airbag installed on the outside of the main shaft and on one side of the end plate, thirty-six first extended umbrella-shaped ribs rotatably connected at equal intervals on the outside of the end plate, a movable connecting seat slidably sleeved on the outside of the main shaft, thirty-six main support rods rotatably connected at equal intervals on the outside of the movable connecting seat, a connecting node fixedly installed at one end of each main support rod, one end of each first extended umbrella-shaped rib rotatably connected to the connecting node, one end of each main support rod being connected to a second extended umbrella-shaped rib through the connecting node, and the ends of the second extended umbrella-shaped ribs away from the main support rods being connected to a third extended umbrella-shaped rib through the connecting node.

[0007] Preferably, the end of the second extended umbrella rib is connected to the first extended umbrella rib by a first reinforcing rib, and the end of the third extended umbrella rib is connected to the main support rod by a second reinforcing rib.

[0008] Preferably, the sealing rubber airbag is provided with thirty-six clearance grooves, the main support rod passes through the clearance grooves provided on the surface of the sealing rubber airbag, and a number of fixing rings are fixedly installed on the outer wall surface of the sealing rubber airbag and respectively fixedly connected to the first expansion umbrella rib, the second expansion umbrella rib, and the third expansion umbrella rib.

[0009] Preferably, an exhaust pipe is installed on the surface of the sealing rubber airbag, and a sealing cap for sealing the exhaust pipe is screwed onto one end of the exhaust pipe.

[0010] Preferably, two support seats are fixedly sleeved on the outer side of the main shaft, and the bottom walls of the two support seats are connected to a base. A hydraulic push rod is installed on the support seat. One end of the movable connecting seat is connected to a movable sleeve. The movable sleeve is slidably sleeved and connected to the outer side of the main shaft. A push seat is fixedly connected to the outer wall of the movable sleeve. The free end of the hydraulic push rod is connected to the push seat.

[0011] Preferably, a one-way valve is bolted to the support base, and a discharge pipe is connected to the output end of the one-way valve. The discharge pipe passes through the central shaft of the main shaft, and multiple connecting pipes are connected to one end of the discharge pipe. The discharge pipe is connected to the sealing rubber airbag through the multiple connecting pipes.

[0012] Preferably, the one-way valve input end is connected to an input pipe, and one end of the input pipe is connected to the output end of the pneumatic high-pressure pump.

[0013] Preferably, a rotary sealing ring is threadedly connected to the outer side of the end of the main shaft near the end plate, and an external thread is provided on the outer side of the end of the main shaft near the end plate to engage with the rotary sealing ring. A sealing rubber ring is installed on the side of the rotary sealing ring that is in contact with the sealing rubber airbag.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with the prior art, the movable connecting seat and the main support rod are designed to work together to allow the end of the main support rod away from the movable connecting seat to push the first extended umbrella-shaped bone to rotate and unfold. Simultaneously, the first tension rib connecting the first and second extended umbrella-shaped bones, through its rotation and unfolding, causes the second extended umbrella-shaped bone to rotate and unfold around its connection point with the main support rod. Similarly, the second extended umbrella-shaped bone, through its interaction with the second tension rib, enables the rotation and unfolding of the third extended umbrella-shaped bone. Finally, the unfolded first, second, and third extended umbrella-shaped bones unfold the sealing rubber airbag, which is fixedly connected by a fixing ring. High-pressure gas is then injected into the sealing rubber airbag, causing it to expand and press against the joint with the well wall, thus achieving a high sealing effect.

[0016] 2. Compared with the existing technology, the hydraulic push rod installed on the support base allows the push seat, which is fixedly connected to the outside of the movable sleeve, to move along the main shaft. The pushed movable sleeve then pushes the movable connecting seat and one end of the main support rod rotatably connected to the movable connecting seat to rotate, thereby quickly unfolding the first extended umbrella rib, the main support rod, the second extended umbrella rib, and the sealing rubber airbag connected to them. This facilitates the rapid unfolding of the sealing rubber airbag during use, and allows it to be stored away when not in use, reducing the overall space occupied by the device, making it easy to fold and store, and improving the practicality of the device.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] As attached Figures 1 to 6 The illustrated assembly-type quick-release and quick-installation pipe sealing robot includes a main spindle 1, with an end plate 2 connected to one end of the main spindle 1. A sealing rubber airbag 3 is then installed on the outside of the main spindle 1 and on one side of the end plate 2. Thirty-six first expansion umbrella ribs 4 are rotatably connected at equal intervals on the outside of the end plate 2. A movable connecting seat 10 is slidably sleeved on the outside of the main spindle 1, and thirty-six main support rods 5 are rotatably connected at equal intervals on the outside of the movable connecting seat 10. A connecting node 25 is fixedly installed at one end of each main support rod 5, and one end of each first expansion umbrella rib 4 is rotatably connected to the connecting node 25. A second expansion umbrella rib 6 is connected to one end of each main support rod 5 through the connecting node 25. Finally, a third expansion umbrella rib 7 is connected to the end of each second expansion umbrella rib 6 away from the main support rod 5 through the connecting node 25.

[0027] In use, the device first moves one end of the main support rod 5 by adjusting the movable connecting seat 10. Then, the end of the main support rod 5 away from the movable connecting seat 10 pushes the first expansion umbrella rib 4, the second expansion umbrella rib 6, and the third expansion umbrella rib 7 to rotate and unfold. Then, the unfolded first expansion umbrella rib 4, second expansion umbrella rib 6, and third expansion umbrella rib 7 unfold the sealing rubber airbag 3, which is fixedly connected by the fixing ring 18. Then, high-pressure gas is injected into the sealing rubber airbag 3, causing the sealing rubber airbag 3 to expand and bulge, so that the sealing rubber airbag 3 squeezes and seals the joint with the well wall, thereby achieving a high sealing effect. At the same time, the edge of the third expansion umbrella rib 7 is provided with rough texture, which can increase the friction between the edge of the third expansion umbrella rib 7 and the well wall, so that the device is pressed tightly against the inner wall of the well, and the device is prevented from shifting during subsequent sealing.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details:

[0030] In a preferred embodiment, the end of the second extended umbrella rib 6 is connected to the first extended umbrella rib 4 via a first reinforcing rib 8, and the end of the third extended umbrella rib 7 is connected to the main support rod 5 via a second reinforcing rib 9. Furthermore, when the first extended umbrella rib 4, the second extended umbrella rib 6, and the third extended umbrella rib 7 are unfolded, the end of the main support rod 5 away from the movable connecting seat 10 first pushes the first extended umbrella rib 4 to rotate and unfold. Then, through the cooperation of the first reinforcing rib 8 connecting the first extended umbrella rib 4 and the second extended umbrella rib 6, one end of the first extended umbrella rib 4 rotates and unfolds simultaneously with the first reinforcing rib 9 connecting the second extended umbrella rib 6 to the main support rod 5. A reinforcing rib 8 pulls the second extended umbrella rib 6 to rotate and unfold around the connection node 25 at one end of the main support rod 5. Similarly, the second extended umbrella rib 6, through its cooperation with the second reinforcing rib 9, enables the rotation and unfolding of the third extended umbrella rib 7. Finally, through the unfolding of the first extended umbrella rib 4, the second extended umbrella rib 6, and the third extended umbrella rib 7, the sealing rubber airbag 3, which is fixedly connected by the fixing ring 18, is unfolded. The minimum sealing area of ​​the sealing umbrella composed of the first extended umbrella rib 4, the second extended umbrella rib 6, and the third extended umbrella rib 7 can be adapted to pipelines with a diameter of 400mm.

[0031] In a preferred embodiment, thirty-six clearance grooves 17 are provided on the sealing rubber airbag 3, and thirty-six main support rods 5 pass through the clearance grooves 17 on the surface of the sealing rubber airbag 3. Then, several fixing rings 18 are fixedly installed on the outer wall surface of the sealing rubber airbag 3, which are respectively fixedly connected to the first expansion umbrella rib 4, the second expansion umbrella rib 6, and the third expansion umbrella rib 7. Furthermore, the clearance grooves 17 on the sealing rubber airbag 3 facilitate the connection of the main support rods 5 through the sealing rubber airbag 3 to the second expansion umbrella rib 6, while supporting the rotation of the first expansion umbrella rib 4. Then, the fixing rings 18 facilitate the deployment of the sealing rubber airbag 3 while the first expansion umbrella rib 4, the second expansion umbrella rib 6, and the third expansion umbrella rib 7 are deployed.

[0032] In a preferred embodiment, an exhaust pipe 19 is installed on the surface of the sealing rubber airbag 3, and a sealing cap 20 is screwed onto one end of the exhaust pipe 19. The sealing cap 20 can seal the exhaust pipe 19. Furthermore, when the entire device needs to be stored, the sealing cap 20 connected to the outside of the exhaust pipe 19 can be screwed open first, and then the high-pressure gas in the sealing rubber airbag 3 can be quickly discharged through the exhaust pipe 19, which facilitates the release of gas.

[0033] In a preferred embodiment, two support seats 15 are fixedly sleeved on the outside of the main shaft 1, and a base 14 is connected to the bottom wall of the two support seats 15. A hydraulic push rod 13 is installed on the support seats 15. A movable sleeve 11 is connected to one end of the movable connecting seat 10. The movable sleeve 11 is slidably sleeved on the outside of the main shaft 1, and a push seat 12 is fixedly connected to the outer wall of the movable sleeve 11. Finally, the free end of the hydraulic push rod 13 is connected to the push seat 12. Furthermore, in use, the push seat 12 can be moved by the hydraulic push rod 13 on the support seats 15. The pusher causes the pusher seat 12 to move along the main shaft 1. The pushed movable sleeve 11 then pushes the movable connecting seat 10 and one end of the main support rod 5, which is rotatably connected to the movable connecting seat 10, to rotate. This allows the first extended umbrella rib 4, the main support rod 5, the second extended umbrella rib 6, and the sealing rubber airbag 3 connected to them to be quickly deployed. This facilitates the rapid deployment of the sealing rubber airbag 3 during use and allows for quick storage when not in use, reducing the overall space occupied by the device and making it easy to fold and store, thus improving the practicality of the device.

[0034] In a preferred embodiment, a one-way valve 23 is bolted to the support base 15, and a discharge pipe 21 is connected to the output end of the one-way valve 23. The discharge pipe 21 passes through the central shaft of the main shaft 1, and multiple connecting pipes 22 are connected to one end of the discharge pipe 21. One end of the discharge pipe 21 is connected to the sealing rubber airbag 3 through the multiple connecting pipes 22. An input pipe 24 is connected to the input end of the one-way valve 23, and one end of the input pipe 24 is connected to the output end of the high-pressure air pump. Furthermore, when the device is in use, the one-way valve 23 can be opened, and the power supply of the high-pressure air pump connected to one end of the input pipe 24 can be turned on. Then, the high-pressure air pump injects high-pressure gas into the discharge pipe 21 through the input pipe 24 and the one-way valve 23. Then, the discharge pipe 21 injects high-pressure gas into the sealing rubber airbag 3 through the multiple connecting pipes 22, causing the sealing rubber airbag 3 to expand rapidly, thereby squeezing and sealing the joint between the sealing rubber airbag 3 and the well wall.

[0035] In a preferred embodiment, a rotary sealing ring 16 is threadedly connected to the outer side of the main shaft 1 near the end plate 2. The outer side of the main shaft 1 near the end plate 2 has an external thread that engages with the rotary sealing ring 16. A sealing rubber ring is installed on the side of the rotary sealing ring 16 that is close to the sealing rubber airbag 3. Furthermore, the rotary sealing ring 16 further seals the connection between the main shaft 1 and the sealing rubber airbag 3, improving the sealing effect of the entire device on the pipeline. In use, the rotary sealing ring 16 can be rotated to a suitable position, and then high-pressure gas can be injected into the sealing rubber airbag 3. Subsequently, the inflated sealing rubber airbag 3 compresses the rotary sealing ring 16, sealing the gap between the rotary sealing ring 16 and the sealing rubber airbag 3. Finally, the rotary sealing ring 16 can be rotated using external tools to bring it closer to the sealing rubber airbag 3, thereby improving the sealing performance between the rotary sealing ring 16 and the sealing rubber airbag 3.

[0036] The working process of this utility model is as follows: First, the base 14 is fixed. Then, the first extended umbrella rib 4, the second extended umbrella rib 6, and the third extended umbrella rib 7 are unfolded. During unfolding, the hydraulic push rod 13 on the support base 15 can push the push seat 12, causing the push seat 12 to move along the main shaft 1. The pushed movable sleeve 11 then pushes the movable connecting seat 10 and one end of the main support rod 5 rotatably connected to the movable connecting seat 10 to rotate. Subsequently, the end of the main support rod 5 away from the movable connecting seat 10 pushes the first extended umbrella rib 4 to rotate and unfold. Then, through the cooperation of the first tensile rib 8 connecting the first extended umbrella rib 4 and the second extended umbrella rib 6, the unfolded umbrella rib 4 is further unfolded. The first extended umbrella rib 4 rotates and unfolds at one end, while the second extended umbrella rib 6 is pulled by the first tension rib 8 to rotate and unfold with the connection node 25 at one end of the main support rod 5 as the rotation point. Similarly, the second extended umbrella rib 6, which rotates and unfolds, is set up in cooperation with the second tension rib 9 to realize the rotation and unfolding of the third extended umbrella rib 7. Finally, the first extended umbrella rib 4, the second extended umbrella rib 6, and the third extended umbrella rib 7 are unfolded, and the sealing rubber airbag 3, which is fixedly connected by the fixing ring 18, is unfolded. At the same time, when not in use, the sealing rubber airbag 3 can be quickly stored, reducing the overall space occupied by the device, making it convenient for storage and folding, and improving the practicality of the device.

[0037] When it is necessary to introduce high-pressure gas into the sealing rubber airbag 3, the one-way valve 23 can be opened, and the power supply of the high-pressure air pump can be connected by opening one end of the input pipe 24. Then, the high-pressure air pump injects high-pressure gas into the discharge pipe 21 through the input pipe 24 and the one-way valve 23. Then, the discharge pipe 21 injects high-pressure gas into the sealing rubber airbag 3 through multiple connecting pipes 22, causing the sealing rubber airbag 3 to expand rapidly. In turn, the sealing rubber airbag 3 squeezes and seals the joint between the sealing rubber airbag 3 and the well wall, thereby achieving a high sealing effect. The above is the working principle of this prefabricated quick-disassembly and quick-installation pipeline sealing robot.
