Description

Technical Field

[0001] This utility model relates to the field of detection and positioning equipment, and in particular to a pipeline damage detection and positioning device. Background Technology

[0002] Underground pipelines refer to various pipeline systems buried underground, used to transport substances such as water, natural gas, oil, and sewage, or as conduits for cables. These pipelines are an important part of urban infrastructure, playing a crucial role in ensuring the normal operation of cities. Metal pipelines are one type of underground pipeline. After prolonged use, the anti-corrosion layer of metal pipelines may be damaged. When the anti-corrosion layer is damaged, the exposed metal part loses its protection and comes into direct contact with moisture, oxygen, and other corrosive media in the air. This accelerates the corrosion process of the pipeline, thereby reducing its service life. Therefore, it is necessary to use specialized pipeline damage detection and location equipment to detect and locate damage to the anti-corrosion layer of the pipeline, so as to repair the anti-corrosion layer in a timely manner and allow the anti-corrosion layer to continue to provide effective protection for the pipeline.

[0003] The existing publication number CN208953483U discloses a device for accurately locating and detecting damage to the anti-corrosion layer of buried metal pipelines. It uses a magnetic wave detector to emit magnetic waves to detect the unique metal elements in the metal pipeline. The anti-corrosion layer of the pipeline also contains different kinds of elements. When the element is detected by the magnetic wave detector, it is determined to be damaged. The data fed back by the magnetic wave can be analyzed and processed by the control panel to locate the damage.

[0004] However, the existing patent still has the following problems: 1. The position of the magnetic wave detector is fixed. If the damage point of the anti-corrosion layer of the pipeline is on the side surface of the pipeline, the side position will result in a longer signal transmission path or an unsatisfactory angle. This may lead to a reduction in the effective signal strength received. In addition, the fixed position of the magnetic wave detector may miss some minor damage points due to the angle problem, reducing the accuracy of the pipeline detection results; 2. The magnetic wave detector is exposed after use and lacks a protective structure. It is easily damaged by external forces. At the same time, external dust and impurities are also easy to accumulate at the detection end of the magnetic wave detector, affecting the accuracy of its detection results and hindering the stable use of the detection and positioning equipment. Summary of the Invention

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a pipeline damage detection and positioning device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pipeline damage detection and positioning device, including a chassis and a detection and positioning component disposed in the chassis, the detection and positioning component including an arc-shaped electric guide rail installed in the chassis, a sliding frame slidably installed on the arc-shaped electric guide rail, and a support cylinder detachably installed on the sliding frame;

[0007] The bottom surface of the chassis has an opening located below the arc-shaped electric guide rail;

[0008] The bottom end face of the support cylinder is an open structure. A magnetic wave detector is installed inside the support cylinder, facing the center of the arc-shaped electric guide rail. A rotary motor is detachably installed on the side surface of the support cylinder. A baffle is installed on the bottom output shaft of the rotary motor. The baffle is located below the support cylinder and the magnetic wave detector.

[0009] The arc-shaped electric guide rail, magnetic wave detector, and rotary motor are all electrically connected to the controller mounted on the side surface of the chassis.

[0010] Preferably, a roller is installed at each of the four ends of the bottom of the chassis.

[0011] Preferably, a handle is fixedly mounted on the side surface of the chassis.

[0012] Preferably, a sponge sheet is attached to the bottom end face of the support cylinder, and the sponge sheet is attached to the top end face of the baffle.

[0013] Preferably, a reflective infrared sensor is installed on each of the left and right ends of the inner side of the chassis, and a sensing plate is installed on each of the left and right ends of the sliding frame. The two sensing plates correspond one-to-one with the two reflective infrared sensors, and the reflective infrared sensors are electrically connected to the controller.

[0014] The beneficial effects of this utility model are:

[0015] This invention incorporates an arc-shaped electric guide rail and a baffle. A sliding frame drives the support cylinder and magnetic wave detector along the arc-shaped electric guide rail, allowing the magnetic wave detector to probe the pipeline from different positions, thus obtaining more comprehensive information. Furthermore, the magnetic wave detector remains directly facing the pipeline during movement, improving the accuracy of detecting damage points in the pipeline's anti-corrosion layer. The baffle also provides shielding protection for the magnetic wave detector after use, reducing damage from external forces and minimizing the accumulation of dust and impurities at the detector's probe end. This contributes to improving the accuracy of the magnetic wave detector's detection results and enhancing the stable operation of the detection and positioning equipment.

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] like Figure 1 As shown, this utility model provides a pipeline damage detection and positioning device, including a housing 1 and a detection and positioning component installed inside the housing 1;

[0023] In this embodiment, a roller 10 is installed at each of the four ends of the bottom of the chassis 1. The rollers facilitate the overall movement of the detection and positioning device, improving the overall convenience of the device.

[0024] In this embodiment, a handle 14 is fixedly mounted on the side surface of the chassis 1, which facilitates pushing and pulling the chassis 1 through the handle 14;

[0025] like Figures 1 to 4 As shown, in this embodiment, the detection and positioning component includes an arc-shaped electric guide rail 2 installed in the housing 1, a sliding frame 3 slidably installed on the arc-shaped electric guide rail 2, and a support cylinder 4 locked and fixed on the sliding frame 3.

[0026] An opening 6 is provided on the bottom surface of the chassis 1, located below the arc-shaped electric guide rail 2;

[0027] The bottom end of the support cylinder 4 is an open structure. Inside the support cylinder 4, a magnetic wave detector 5 is installed, which is directly opposite the center of the arc-shaped electric guide rail 2. The magnetic wave detector 5 is used to detect and locate the damage point of the pipeline. A rotary motor 7 is locked and fixed on the right end of the support cylinder 4.

[0028] A baffle 8 is fixedly installed on the bottom output shaft of the rotary motor 7. The baffle 8 is located below the support cylinder 4 and the magnetic wave detector 5. The baffle 8 shields the magnetic wave detector 5, reducing the accumulation of external dust and impurities on the detection end of the magnetic wave detector 5.

[0029] The arc-shaped electric guide rail 2, the magnetic wave detector 5, and the rotary motor 7 are all electrically connected to the controller 13 mounted on the side surface of the chassis 1.

[0030] In this embodiment, a sponge sheet 9 is attached to the bottom end face of the support cylinder 4. The sponge sheet 9 is attached to the top end face of the baffle 8, which reduces the noise generated when the baffle 8 is in direct contact with the support cylinder 4, and also improves the sealing performance when the baffle 8 is in contact with the support cylinder 4, reducing the entry of external dust and impurities into the detection end of the magnetic wave detector 5.

[0031] In this embodiment, the rotary motor 7 is a servo motor, which is convenient to receive feedback signals and adjust the rotation angle of its output shaft, thereby facilitating the adjustment of the position of the baffle 8.

[0032] In this embodiment, a reflective infrared sensor 11 is installed on each of the left and right ends of the inner side of the chassis 1, and a sensor plate 12 is installed on each of the left and right ends of the sliding frame 3. The two sensor plates 12 correspond one-to-one with the two reflective infrared sensors 11. The reflective infrared sensors 11 are electrically connected to the controller 13, so that the position of the sliding frame 3 can be detected by the reflective infrared sensors 11 in conjunction with the sensor plates 12, thereby transmitting the position of the sliding frame 3 to the controller 13. Then, the controller 13 controls the closing of the arc-shaped electric guide rail 2, timely adjusts the arc-shaped electric guide rail 2, and reduces the excessive sliding of the sliding frame 3 on the arc-shaped electric guide rail 2 and the collision with the inner wall of the chassis 1.

[0033] Specifically, during use, pushing the handle 14 drives the roller 10 to rotate, moving the entire detection and positioning device to the appropriate position. The controller 13 activates the magnetic wave detector 5 to emit magnetic waves that pass through the opening 6 to detect the metal elements in the pipe. The pipe anti-corrosion layer also contains different types of elements. When the element is detected by the magnetic wave detector 15, it is identified as a damage, and the data is transmitted to the controller 13 to realize the detection and positioning of the damage point of the pipe anti-corrosion layer.

[0034] When in use, the arc-shaped electric guide rail 2 can be activated to drive the sliding frame 3 to move along the arc-shaped electric guide rail 2. The sliding frame 3 drives the support cylinder 4 and the magnetic wave detector 5 to move synchronously, which makes it easier for the magnetic wave detector 5 to detect the pipeline at different positions, thereby obtaining more comprehensive information about the pipeline. The position of the housing 1 can be adjusted so that the housing 1 is roughly above the pipeline, so that the arc-shaped electric guide rail 2 is roughly above the pipeline. Since the arc-shaped electric guide rail 2 is set in an arc shape, the support cylinder 4 drives the magnetic wave detector 5 to always be directly facing the center of the arc-shaped electric guide rail 2, so that the magnetic wave detector 5 can be better aligned with the pipeline, improving the accuracy of detecting the damage points of the pipeline anti-corrosion layer.

[0035] After the magnetic wave detector 5 is used, the rotary motor 7 is started to drive the baffle 8 to reset and cover the bottom of the support cylinder 4 and the magnetic wave detector 5, so as to reduce the entry of external dust and impurities into the detection end of the magnetic wave detector 5, which helps to provide better protection for the magnetic wave detector 5.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
