Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to an auxiliary device based on periscope pipeline detection. Background Art

[0002] Urban sewage pipe network plays a very important role in the normal operation of the city and flood control and drainage process. It is also an important infrastructure in my country and is called the "blood vessels" of urban construction and development. Its safety greatly affects the safety of people's lives and property. At present, sewage pipe mixing, pipeline flaw detection, and pipeline non-excavation repair are in full swing across the country. Pipeline detection methods are mainly divided into:

[0003] 1. Traditional survey methods, such as reflector detection method, diver detection method, mud bucket detection method, etc.

[0004] 2. External investigation methods, such as infrared temperature recorder method, flaw detection radar method, impact echo method, surface wave spectroscopy method, etc.;

[0005] 3. Internal investigation methods, such as sonar detection, periscope method (QV), closed-circuit television detection technology (CCTV), etc.

[0006] Based on comprehensive practical experience, compared with traditional inspection methods and external inspection methods, internal inspection methods have the characteristics of being able to directly reflect internal defects of pipelines and causing less damage to pipelines; among them: the periscope method (QV) is a commonly used rapid detection equipment for pipelines.

[0007] The periscope method refers to: using a handle with adjustable length to place a high-magnification camera into a cellar or hidden space to inspect the pipeline. The inspection conditions are: the water level in the pipeline ≤ 1 / 2 of the pipe diameter, and the pipe section length ≤ 50m. It has the advantages of no need for personnel to go down the well, fast speed, and adjustable focal length. In actual operation, the bottom of the handle is against the bottom of the sewage pipe to be inspected (that is, the camera is supported only by a single handle, and the inspector needs to hold the handle at all times to ensure that the camera remains stable and does not fall over). By manually turning the handle, the camera is rotated to realize the inspection of different positions of the well wall of the pipeline to be inspected. In this operation, since there will be a lot of silt at the bottom of the pipe, using the bottom of the handle as a support point, it is inconvenient to manually turn the handle, which will affect the rotation of the camera, and thus affect the inspection efficiency of the pipeline.

[0013] Furthermore, the diameter of the operating handle is d4, wherein: d4<d1. Thus, by the design of d4<d1, it is ensured that the operating handle will not abut against the fixed plate, so that it is convenient for the inspector to operate the rotation of the rotating plate through the operating handle.

[0014] Furthermore, there are two cylinders in total, which are symmetrically arranged about the fixed plate, and the number of the slide slots, the cameras and the rotating mechanisms is equal to the number of the cylinders. Therefore, the two symmetrically arranged cylinders can, on the one hand, keep the entire device balanced, making it easier to use and transport the entire device, and on the other hand, make the rotation range of the camera between 0° and 180°, which can reduce the rotation angle of the camera and facilitate the rotation adjustment of the camera.

[0015] Furthermore, the rotating mechanism also includes: a first connecting block, which is located on a side of the rotating plate away from the operating handle and connected to the rotating plate, the first connecting block extends to the outside of the slide groove, and the cylinder is connected to the first connecting block.

DETAILED DESCRIPTION

[0030] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0031] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 1 to 6 As shown, it is the best embodiment of the utility model. The auxiliary device based on periscope pipeline detection in this embodiment includes: a fixed plate 1, a cylinder 2 and a rotating mechanism 4. The telescopic end of the cylinder 2 is equipped with a camera 3. The rotating mechanism 4 includes: a rotating plate 401 and an operating handle 402. The rotating plate 401 is embedded in the fixed plate 1 and is rotatably connected with the fixed plate 1. The operating handle 402 is installed at one end of the rotating plate 401, and the cylinder 2 is installed at the other end of the rotating plate 401. Therefore, during the detection, the fixed plate 1 is placed on the top of the sewage pipe to be detected, and the camera 3 is adjusted up and down by the extension and contraction of the cylinder 2. The rotation of the rotating plate 401 is controlled by the operating handle 402 to realize the horizontal rotation adjustment of the camera 3. Compared with the adjustment method of the rotating handle, this method has a simple structure and is easy to operate. It can facilitate the adjustment of the position of the camera 3, so that the camera 3 is aligned with the detection position of the sewage pipe to be detected, thereby improving the detection efficiency of the sewage pipe.

[0034] In other words, during detection, the fixed plate 1 is placed on the top of the sewage pipe to be detected. At this time, the camera 3 is adjusted up and down and rotated with the fixed plate 1 as the support point. The fixed plate 1 does not need to be rotated, and the camera 3 always remains stable and will not fall over in the sewage pipe. On the one hand, the resistance to rotation can be reduced (the existing handle is in contact with the bottom of the sewage pipe to be detected, and the silt at the bottom will hinder the rotation of the handle). On the other hand, the camera 3 is not stable and may fall over if it is supported only by the handle. However, in the present design, there is no obstruction of silt during rotation adjustment. During detection, there is no need to hold the entire device by hand, which can facilitate the adjustment of the position of the camera 3, thereby improving the detection efficiency of the sewage pipe.

[0035] Specifically, the up and down adjustment of the camera 3 refers to the change in the depth of the camera 3 in the sewage pipe; the rotation adjustment of the camera 3 refers to the rotation of the camera 3 around the center point O of the fixed plate 1 at the same depth to reach different positions of the sewage pipe at that depth.

[0036] In this embodiment, the fixed plate 1 is provided with a slide groove 101, and both sides of the slide groove 101 are provided with a limiting groove 102. The central part of the rotating plate 401 is located in the slide groove 101, and the end of the rotating plate 401 is located in the limiting groove 102; the operating handle 402 extends to the outside of the slide groove 101. Therefore, through the mutual cooperation between the slide groove 101 and the limiting groove 102, the rotating plate 401 can be embedded in the fixed plate 1 without falling and can rotate; the operating handle 402 extends to the outside of the slide groove 101, which can facilitate the inspection personnel to operate the rotating plate 401 through the operating handle 402 to realize the rotation adjustment of the rotating plate 401 relative to the fixed plate 1.

[0037] In this embodiment, the width of the chute 101 is d1, the depth of the limit groove 102 is d2, the diameter of the rotating plate 401 is d3, and the diameter of the operating handle 402 is d4; wherein: d1<d3=d1+2d2, d4<d1. Thus, by the design of d1<d3, it is ensured that the rotating plate 401 is embedded in the fixed plate 1, will not fall and can rotate; by the design of d3=d1+2d2, it is ensured that the rotating plate 401 always abuts against the fixed plate 1, can only rotate relative to the fixed plate 1 in the chute 101 and the limit groove 102, and cannot slide relative to the fixed plate 1, so as to improve the stability of the camera 3, and facilitate the detection of the sewage pipe through the camera 3; by the design of d4<d1, it is ensured that the operating handle 402 will not abut against the fixed plate 1, so that it is convenient for the detection personnel to operate the rotation of the rotating plate 401 through the operating handle 402.

[0038] In this embodiment, there are two cylinders 2, which are symmetrically arranged about the fixed plate 1, and the number of the slide slots 101, the cameras 3 and the rotating mechanism 4 is equal to the number of the cylinders 2. Therefore, the two symmetrically arranged cylinders 2, on the one hand, can keep the whole device balanced, which is convenient for the use and transportation of the whole device, and on the other hand, make the rotation range of the camera 3 between 0° and 180°, which can reduce the rotation angle of the camera 3 and facilitate the rotation adjustment of the camera 3.

[0039] In this embodiment, the rotating mechanism 4 also includes: a first connecting block 403, which is located on the side of the rotating plate 401 away from the operating handle 402 and is connected to the rotating plate 401, and the first connecting block 403 extends to the outside of the slide groove 101, and the cylinder 2 is connected to the first connecting block 403.

[0040] In this embodiment, it also includes a fixing mechanism 5, which includes a sleeve rod 501, a sliding rod 502, two first fixing rods 503 and two second fixing rods 504. The sleeve rod 501 is rotatably connected to the fixing plate 1, one end of the sliding rod 502 is inserted into the sleeve rod 501 and is slidably connected to the sleeve rod 501, the two ends of the first fixing rod 503 are respectively connected to the sleeve rod 501 and the first connecting block 403, and the two ends of the second fixing rod 504 are respectively connected to the other end of the sliding rod 502 and the telescopic end of the cylinder 2. In this way, it can ensure that the two cameras 3 rotate synchronously and the cameras 3 remain stable without shaking.

[0041] In this embodiment, a second connecting block 201 is provided at the telescopic end of the cylinder 2, the camera 3 is located on the side of the second connecting block 201 away from the second fixing rod 504 and is connected to the second connecting block 201, and the second fixing rod 504 is located on the side of the second connecting block 201 away from the camera 3 and is connected to the second connecting block 201.

[0042] In this embodiment, it also includes: two handles 6 and a plurality of universal wheels 7. The handle 6 is located on the side of the fixing plate 1 away from the cylinder 2 and connected to the fixing plate 1. The two handles 6 are symmetrically arranged about the fixing plate 1, located on the side of the fixing plate 1 away from the cylinder 2 and connected to the fixing plate 1. Therefore, the handles 6 can facilitate the staff to carry the entire device; the plurality of universal wheels 7 can facilitate the transportation of the entire device.

[0043] To sum up, during detection, the utility model places the fixed plate 1 on the top of the sewage pipe to be detected, and realizes the up and down adjustment of the camera 3 by extending and retracting the cylinder 2. The rotation of the rotating plate 401 is controlled by the operating handle 402 to realize the horizontal rotation adjustment of the camera 3. Compared with the adjustment method of rotating the handle, this method has a simple structure and is easy to operate. It can facilitate the adjustment of the position of the camera 3, so that the camera 3 is aligned with the detection position of the sewage pipe to be detected, thereby improving the detection efficiency of the sewage pipe.
