Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection, and in particular to a non-destructive inner wall detection device for a municipal pipeline. Background Art

[0002] Municipal pipelines need to be inspected regularly. Inner wall inspection can find potential problems inside the pipeline, such as corrosion, scaling, cracks, etc. These problems may cause pipeline leakage, rupture and other safety accidents. Through inner wall inspection, these problems can be discovered and solved in time, thus ensuring the safe operation of the pipeline.

[0003] Application No. 202120486204.6 discloses a non-destructive inner wall detection device for municipal pipelines, including a camera, a motor, a moving block, a hinge and a spring, etc. By arranging a control device and a propulsion device in the main body, when it is necessary to detect pipelines of different sizes, the motor is controlled to work by an external power supply, which drives the first cone wheel to rotate, and the first cone wheel drives the second cone wheel and the connecting shaft to rotate, and the first screw segment and the second screw segment on both sides of the connecting shaft rotate accordingly, and the moving block and the push rod thereon move simultaneously and push the directional rod to move, and the directional rod drives the moving wheels on both sides to move. The device can effectively adjust the spacing between the moving wheels on both sides of the main body to facilitate its adaptation to pipelines of different sizes. At the same time, by arranging a moving mechanism in the main body, when encountering a protruding foreign object in the pipeline, the moving wheel contacts the object, and it is resisted by the object and pushes the moving wheel. The movable rod at the rear end of the moving wheel moves toward the inside of the directional rod and squeezes the spring. At this time, the main body passes through the foreign object smoothly, and the spring elastic force resets it again. The device can effectively protect the inner wall of the pipeline and the main body of the device to avoid damage caused by collision or foreign objects.

[0004] However, in use, there are the following defects:

[0005] Although the position of the moving wheel can be adjusted so that it can adapt to pipes of different sizes, and a squeezing spring is set to allow the moving wheel to pass through foreign objects smoothly, the different sizes of the debris when moving in the pipe may block the device and prevent it from passing, thereby affecting the detection efficiency. Utility Model Content

[0006] The purpose of the present application is to provide a municipal pipeline non-destructive inner wall detection device, which solves the problem proposed in the background technology that although the position of the moving wheel can be adjusted so that it can adapt to pipelines of different sizes, and a squeezing spring is provided to enable the moving wheel to pass through foreign objects smoothly, the size of the debris is different when moving in the pipeline, which may block the device and cause the device to be unable to pass, thereby affecting the detection efficiency.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a municipal pipeline non-destructive inner wall detection device, comprising a cylinder, a support shaft, a spring, a connecting rod and a guide plate, an opening at one end of the cylinder is provided with an inclined groove, and an opening at the other end of the cylinder is provided with three guide grooves, and the left and right inner walls of the guide groove are evenly inlaid with a plurality of support shafts, and the left and right support shafts are respectively detachably connected to the two ends of a rotating rod, and the surface of the rotating rod is transmission-connected with a crawler, and four storage rods are symmetrically distributed and fixedly connected to the upper and lower sides of the outer wall of the cylinder, and the two ends of the storage rods are movably sleeved and connected with telescopic rods.

[0008] In this technical solution, a rope is tied to the pull buckle so that the device can be pulled to move in the pipeline, and the device can be quickly pulled out by directly pulling the rope after the detection is completed. The length of the telescopic rod can be adjusted through the storage groove so that the action wheel can contact the inner wall of the pipeline. At the same time, the spring in the storage groove can slide to the inside of the storage groove when the connecting rod is compressed, and slide out again after the compression contact, so that it can pass more conveniently when encountering debris. The camera can shoot forward during the movement. The obstruction of debris to the device can be reduced through the inclined groove, the guide groove, the support shaft, the rotating rod and the crawler. When moving in the pipeline, there will be debris accumulated in the pipeline, and the device will be blocked by the debris if it passes directly. A chute is provided at the opening of the cylinder to facilitate the entry of debris. After the debris reaches the outlet chute, the cylinder continues to move forward and the debris will slide backward. At this time, the rotating shaft will rotate under the contact with the debris, thereby driving the crawler to rotate, so that the debris can be more convenient to leave the cylinder, thereby improving the passing efficiency of the device in the pipeline. At the same time, the hinge buckle and the guide plate can facilitate the passage of debris. Different pipelines have different inner diameters. The outer side of the cylinder is in contact with the moving wheel, so that there is a certain gap between it and the inner wall of the pipeline. The guide plate is unfolded forward. During the movement, the debris will enter the chute and the outlet chute under the shoveling of the guide plate, thereby reducing the obstruction of the debris and further improving the passing efficiency of the device.

[0009] As an optional solution of the technical solution of the present application, a storage groove is provided at the outer end of the telescopic rod, a spring is movably installed on the inner side of the storage groove, the connecting rod is slidably connected on the inner side of the storage groove, a fixed shaft is movably installed on the edge of the side wall at the other end of the storage groove, and the fixed shaft is fixedly installed in the center of the side wall of the action wheel.

[0010] As an optional solution of the technical solution of the present application, buckles are fixedly connected to the center of the side walls of the storage rod on the upper and lower sides of the inclined groove.

[0011] As an optional solution of the technical solution of the present application, both ends of the side walls of the storage rod are threadedly connected with fixing bolts.

[0012] As an optional solution of the technical solution of the present application, a camera is embedded and installed on the surface of the inclined groove.

[0013] As an optional solution of the technical solution of the present application, the detachable necklace at the bottom edge of the opening of the inclined groove is provided with a hinged buckle, and the hinged buckle is fixedly connected to the edge of the guide plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can reduce the obstruction of debris to the device through the inclined groove, the outlet groove, the support shaft, the rotating rod and the crawler track. When moving in the pipeline, debris will accumulate in the pipeline, and the device will be blocked by the debris if it passes directly. The inclined groove is opened at the opening of the cylinder to facilitate the entry of debris. After the debris reaches the outlet groove, the cylinder continues to move forward and the debris will slide backward. At this time, the rotating shaft will rotate under the contact with the debris, thereby driving the crawler track to rotate, so that the debris can be more convenient to leave the cylinder, thereby improving the passing efficiency of the device in the pipeline.

[0016] 2. The present application can facilitate the passage of debris through hinged buckles and guide plates. Different pipes have different inner diameters. The outer side of the cylinder is in contact with the moving wheel, so that there is a certain gap between the inner wall of the pipe. The guide plate is unfolded forward.

[0023] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, a non-destructive inner wall detection device for a municipal pipeline includes a cylinder 1, a support shaft 4, a spring 10, a connecting rod 11 and a guide plate 15. An inclined groove 2 is opened at an opening at one end of the cylinder 1. A pull buckle 13 is fixedly connected to the center of the side walls of the storage rods 7 on the upper and lower sides of the inclined groove 2. A camera 16 is embedded and installed on the surface of the inclined groove 2. The pull buckle 13 can be tied with a rope to pull the device to move inside the pipeline, and can be quickly taken out.

[0025] like Figure 1 As shown, a detachable necklace is provided with a hinged buckle 14 at the bottom edge of the opening of the chute 2, and the hinged buckle 14 is fixedly connected to the edge of the guide plate 15. The guide plate 15 can more conveniently shovel the debris, thereby facilitating the passage of the debris.

[0026] like Figure 2 and Figure 3 As shown, three guide grooves 3 are provided at the opening at the other end of the cylinder 1, and a plurality of support shafts 4 are evenly inlaid and installed on the left and right inner walls of the guide grooves 3. The left and right support shafts 4 are detachably connected to the two ends of a rotating rod 6 respectively, and a track 5 is transmission-connected to the surface of the rotating rod 6. The track 5 can make contact inertia when the device moves, making it more convenient for debris to slide out of the cylinder 1.

[0027] like Figure 2 As shown, four storage rods 7 are symmetrically distributed and fixedly connected on the upper and lower sides of the outer wall of the cylinder 1, and telescopic rods 8 are movably sleeved at both ends of the storage rods 7. Fixed bolts 701 are threadedly connected at both ends of the side walls of the storage rods 7. The fixed bolts 701 can adjust the length of the telescopic rods 8 so that the action wheels 12 can contact the inner wall of the pipe.

[0028] like Figure 4 As shown, a storage groove 9 is provided at the outer end of the telescopic rod 8, a spring 10 is movably installed on the inner side of the storage groove 9, a connecting rod 11 is slidably connected on the inner side of the storage groove 9, a fixed shaft 121 is movably installed on the edge of the side wall of the other end of the storage groove 9, and the fixed shaft 121 is fixedly installed in the center of the side wall of the action wheel 12, and the spring 10 can make the connecting rod 11 pop out of the storage groove 9 again when the connecting rod 11 is compressed.

[0029] In actual use, a rope is tied to the pull buckle 13, so that the device can be pulled to move in the pipeline, and the device can be quickly pulled out by directly pulling the rope after the detection is completed. The length of the telescopic rod 8 can be adjusted through the storage groove 9, so that the action wheel 12 can contact the inner wall of the pipeline. At the same time, the spring 10 in the storage groove 9 can slide to the inside of the storage groove 9 when the connecting rod 11 is compressed, and slide out again after the compressed contact, so that it can pass more conveniently when encountering debris. The camera 16 can shoot forward during the movement. Through the inclined groove 2, the guide groove 3, the support shaft 4, the rotating rod 6 and the crawler 5, the obstruction of the device by debris can be reduced. When moving in the pipeline, there will be debris accumulated in the pipeline, and the device will be blocked by the debris if it passes directly. The opening of the cylinder 1 is provided with an inclined slot 2, which can make it easier for debris to enter. After the debris reaches the outlet slot 3, the cylinder 1 continues to move forward, and the debris will slide backward. At this time, the rotating shaft will rotate under the contact with the debris, thereby driving the crawler 5 to rotate, so that the debris can be more convenient to leave the cylinder 1, thereby improving the passing efficiency of the device in the pipeline. At the same time, the hinge buckle 14 and the guide plate 15 can make it easier for debris to pass. Different pipelines have different inner diameters. The outer side of the cylinder 1 is in contact with the moving wheel 12, so that there is a certain gap between it and the inner wall of the pipeline. The guide plate 15 is unfolded forward. During the movement, the debris will enter the inclined slot 2 and the outlet slot 3 under the shoveling of the guide plate 15, thereby reducing the obstruction of the debris and further improving the passing efficiency of the device.
