Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline robots, and more specifically, particularly relates to a splash-proof structure of a pipeline robot with a crushing function. Background Art

[0002] With the development of modern industry and urban infrastructure construction, pipeline systems are widely used in various fields, such as municipal water supply and drainage pipelines, petrochemical transportation pipelines, etc. However, during long-term use of these pipelines, problems such as blockage, scaling, and foreign object deposition are prone to occur inside, seriously affecting the normal operation of the pipelines. To solve these problems, pipeline robots have emerged, and among them, pipeline robots with a crushing function play an important role in dealing with obstacles inside the pipelines.

[0003] Most of the existing pipeline robots with a crushing function need to use a micro breaker to crush obstacles (such as stones, hardened deposits, foreign objects, etc.) inside the pipeline. A large number of fragments will be generated during the crushing process. These fragments will fly out at high speed in all directions under the impact force of the micro breaker. During the process of fragment splashing, it may damage the main body of the pipeline robot. If the fragments hit the sensor, it may interfere with the normal operation of the sensor, affecting the robot's perception of its own position and the surrounding environment. For power components such as motors, the impact of the fragments may damage their outer shells or internal structures, resulting in short circuits or mechanical failures, affecting the normal operation of the robot. Moreover, the splashed wastewater may splash onto the pipeline robot, thereby corroding the components of the pipeline robot and affecting the service life of the pipeline robot.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by providing a splash-proof mechanism, the pipeline robot body of the present application crushes the sediment in the pipeline body through the crushing mechanism body, and the splash-proof mechanism prevents the splashes generated during the crushing of the crushing mechanism body from hitting the pipeline robot body, thereby achieving the effect of protecting the pipeline robot body, and solving the problem that the existing pipeline robot lacks a protection mechanism and affects the service life of the pipeline robot.

[0017] In the present invention, by providing a splash-proof mechanism, the splash-proof mechanism includes a polycarbonate plate, an aluminum alloy plate and a perfluoropolyether coating. The polycarbonate plate plays a role in skeleton support, and the polycarbonate plate itself has the advantages of corrosion resistance and impact resistance, so it has a good protection effect. The aluminum alloy plate is made of metal and plays a major anti-impact effect. The perfluoropolyether coating has excellent chemical stability, extremely low surface energy and good corrosion resistance. After being coated on the aluminum alloy plate, it can form a dense protective film, effectively blocking the erosion of various corrosive media (such as acids, alkalis, salts, etc.) on the aluminum alloy plate, greatly improving the overall corrosion resistance of the splash-proof mechanism and giving the splash-proof mechanism of the present application a long service life.

These wastes will block the second protection mechanism as the pipeline robot body continues to penetrate deeper into the pipeline body. At this time, the driving motor can be used to drive the second protective plate to rotate 180 degrees. At this time, the first protective plate coincides with the second protective plate, leaving a certain space between the splash-proof mechanism and the inner bottom wall of the pipeline body, enabling the splash-proof mechanism to pass smoothly.

[0027] Two fixing rods 506 are fixedly connected to one side of the first protection plate 501 where the arc-shaped baffle 503 is installed. One ends of the two fixing rods 506 away from the first protection plate 501 are commonly fixedly connected with a fixing plate 507. Three through holes 508 are opened on the surface of the fixing plate 507. The first protection plate 501 is fixedly connected with a fixing ring 509.

[0028] The three through holes 508 are respectively sleeved with the three fixing bolts 203. The three hexagonal nuts 204 are respectively threadedly connected to one ends of the three fixing bolts 203 passing through the through holes 508.

[0029] On one side of the first protective plate 501 away from the arc-shaped baffle 503, four cameras 510 and four LED lights 511 are fixedly installed. Both the cameras 510 and the LED lights 511 are arranged inside the first protective plate 501, and the four cameras 510 and the LED lights 511 are electrically connected to the PLC circuit control box 502.

[0030] The second protective plate 601 is fan-shaped. Five second water troughs 602 are formed on the circumferential surface of the second protective plate 601. The second protective plate 601 is fixedly connected with a connecting ring 604, and one end of the connecting ring 604 away from the second protective plate 601 is fixedly connected with a toothed ring 605.

[0031] Four scraping plates 603 are fixedly connected to one side of the second protective plate 601 close to the toothed ring 605. The connecting ring 604 is rotatably connected to the inner side of the fixed ring 509. The scraping plates 603 are in contact with one side of the first protective plate 501 away from the arc-shaped baffle 503, and the scraping plates 603 are in contact with the cameras 510 and the LED lights 511.

[0032] The driving gear 701 is meshed and clamped with the toothed ring 605.

[0033] Both the first protective plate 501 and the second protective plate 601 include a polycarbonate plate 801, an aluminum alloy plate 802 and a perfluoropolyether coating 803. The perfluoropolyether coating 803 is sprayed on the surface of the aluminum alloy plate 802, and the polycarbonate plate 801 is arranged on one side of the first protective plate 501 and the second protective plate 601 close to the pipeline body 1.

[0034] Working principle: In the first step, the pipeline robot body 2 of the present application crushes the sediment in the pipeline body 1 through the crushing mechanism body 3, and the splash prevention mechanism 4 prevents the flying objects generated during the crushing of the crushing mechanism body 3 from hitting the pipeline robot body 2, thereby achieving the effect of protecting the pipeline robot body 2.

[0035] In the second step, first start the driving motor 7 to drive the driving gear 701 to rotate. The driving gear 701 drives the toothed ring 605 to rotate. The toothed ring 605 drives the connecting ring 604 to rotate. The connecting ring 604 drives the second protective plate 601 to rotate, so that the first protective plate 501 and the second protective plate 601 form a circle. The formed circular splash prevention mechanism 4 is adapted to the inner diameter of the pipeline body 1. The first protective plate 501 and the second protective plate 601 can block the crushed stones or other flying objects generated during the operation of the micro crushing hammer 303.

[0036] In the third step, the polycarbonate plate 801 serves as a skeleton support. Moreover, the polycarbonate plate 801 itself has the advantages of corrosion resistance and impact resistance, so it has a good protection effect. The aluminum alloy plate 802 is made of metal and plays a major role in impact prevention. The perfluoropolyether coating 803 has excellent chemical stability, extremely low surface energy, and good corrosion resistance. After being coated on the aluminum alloy plate 802, it can form a dense protective film, effectively blocking the erosion of various corrosive media (such as acids, alkalis, salts, etc.) on the aluminum alloy plate 802, greatly improving the overall corrosion resistance of the splash-proof mechanism 4 and giving it a long service life.

[0037] In the fourth step, after the present application has broken the inside of the pipeline body 1 for a period of time, the surfaces of the camera 510 and the LED lamp 511 may be blocked by splashes. At this time, the driving motor 7 can be used to drive the second protective plate 601 to rotate 360 degrees. During the rotation of the second protective plate 601, the scraper 603 will scrape off the waste on the surfaces of the first protective plate 501, the camera 510, and the LED lamp 511, achieving a cleaning effect.

[0038] In the fifth step, during the actual use of the crushing mechanism body 3, in order not to damage the pipeline body 1 itself, in most cases, the micro crushing hammers 303 cannot completely crush the waste inside the pipeline body 1, and there may be a certain thickness of waste left on the inner bottom wall of the pipeline body 1. These wastes will block the second protective mechanism 6 as the pipeline robot body 2 continues to penetrate deeper into the pipeline body 1. At this time, the driving motor 7 can be used to drive the second protective plate 601 to rotate 180 degrees. At this time, the first protective plate 501 coincides with the second protective plate 601, leaving a certain space between the splash-proof mechanism 4 and the inner bottom wall of the pipeline body 1, enabling the splash-proof mechanism 4 to pass through smoothly. After the pipeline robot body 2 drives the splash-proof mechanism 4 through this section of waste, the splash-proof mechanism 4 can be unfolded.

[0039] In the sixth step, when the present application needs to disassemble and clean the splash-proof mechanism 4, first disassemble and separate the crushing mechanism body 3 from the pipeline robot body 2, then separate the three hex nuts 204 from the three fixing bolts 203. At this time, separate the three through holes 508 of the fixing plate 507 from the three fixing bolts 203, and then separate the flexible circuit connecting the PLC circuit control box 502 to the pipeline robot body 2. At this time, the splash-proof mechanism 4 can be cleaned or maintained separately.
