Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline measurement, and particularly relates to a sewage pipeline inner diameter measuring device. Background Technique

[0002] With the continuous development of society and the improvement of people's living conditions, people's awareness of water resource protection is also constantly increasing. Therefore, the sewage treatment business needs to be further planned and developed to meet the needs of the people. At present, sewage pipelines are an essential part of urban public facilities and drainage systems, playing a very important role in them.

[0003] Since the standard sizes of sewage pipelines may vary due to different construction times, it is necessary to measure the inner diameter of sewage pipelines during construction or renovation. However, most sewage pipelines are buried underground and connected through sewage wells. To measure their inner diameter, it is necessary for workers to enter the inspection wells. Because the environment in the sewage pipelines is relatively harsh, the carbon dioxide content is high, and there may be some volatile poisonous gases, etc., it is dangerous for workers to enter the inspection wells. Therefore, a sewage pipeline inner diameter measuring device is proposed to solve this problem. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that when measuring the inner diameter of a sewage pipeline, workers need to enter the inspection well, and because the gas in the sewage pipeline is different from the outside, it is dangerous for the measuring personnel.

[0005] To solve the above technical problem, the technical solution provided by the utility model is: a sewage pipeline inner diameter measuring device, including a first measuring rod and a second measuring rod. One side of the first measuring rod and the second measuring rod abuts against each other, and the first measuring rod and the second measuring rod are slidably connected through a guiding structure. A protective sleeve is slidably connected to the outer sides of the first measuring rod and the second measuring rod. A vertical upper detection plate is arranged at the bottom of the first measuring rod. A corresponding movable groove is arranged at the position of the protective sleeve corresponding to the upper detection plate. A lower detection plate is arranged below the upper detection plate at the bottom of the second measuring rod. A camera is connected above one end of the lower detection plate away from the second measuring rod. One side of the top of the first measuring rod is rotatably connected to a lifting plate, and a scale is arranged below the lifting plate on the first measuring rod. A positioning block is arranged at the position of the protective sleeve on the outer edge of the second measuring rod. Both the first measuring rod and the second measuring rod are composed of multiple sections connected by plugging.

[0006] Through the above technical solution, the inner diameter of the sewage pipe is measured by the measuring rod one and the measuring rod two with multi-segment structures capable of adjusting the length sliding in the protective sleeve, thus avoiding the extrusion injury to people during the mutual sliding process, and measuring the inner diameter of the sewage pipe by the distance between the measuring rod one and the measuring rod two, without the need for manual entry for measurement, which is relatively safe.

[0007] Preferably, the measuring rod one and the measuring rod two are symmetrically arranged at the center, and the same guiding structure is provided on the measuring rod one and the measuring rod two. The guiding structure is composed of a guiding chute and a guiding slider. A plurality of balls are longitudinally arranged on the guiding slider, and the sides of the plurality of balls are abutted against and slidably connected to the inner sides of both sides of the guiding chute.

[0008] Through the above technical solution, by setting the guiding structure, the sliding between the measuring rod one and the measuring rod two is smoother and easier, reducing the force required during use.

[0009] Preferably, the measuring rod one and the measuring rod two match the shape inside the protective sleeve, and limiting blocks for guiding connection with the protective sleeve are provided on both sides of the measuring rod one and the measuring rod two.

[0010] Through the above technical solution, the outside of the measuring rod one and the measuring rod two is protected by the protective sleeve to prevent pinching during sliding, and the outside of the measuring rod one and the measuring rod two is limited.

[0011] Preferably, the upper detection plate and the lower detection plate are arranged parallel to the ground. The length of the upper detection plate is less than the length of the lower detection plate, and the width of the upper detection plate is the same as the width of the movable groove.

[0012] Through the above technical solution, the bottom and top of the inner diameter of the sewage pipe are respectively abutted by the upper detection plate and the lower detection plate, so as to obtain the inner diameter of the sewage pipe through the separated distance therebetween, and the movement of the upper detection plate is limited by the movable groove. At the same time, external additional devices such as cameras are arranged at the longer end of the lower detection plate.

[0013] Preferably, the bottom of the camera is fixedly connected to the upper part of the lower detection plate through a support column. The camera is an infrared night vision camera, and the camera is equipped with a lighting lamp.

[0014] Through the above technical solution, the support column can increase the height of the camera, and the camera can remotely view the situation inside the sewage pipe without the need for manual entry into the sewage pipe for viewing.

[0015] Preferably, the lifting plate is provided with a corresponding storage opening on the protective sleeve, and the scale is located at the storage opening. The upper end surface of the positioning block is on the same plane as the upper end surface of the second measuring rod, and the positioning block is provided with a corresponding opening at the storage opening. The initial value of the scale is the height of the upper end surface of the second measuring rod.

[0016] Through the above technical solution, the lifting plate can be stored, reducing the occupied volume when not in use, and the scale can be read through the upper end surface of the positioning block.

[0017] Preferably, a limiting rotating plate is rotatably connected to the top of the second measuring rod, and one end of the limiting rotating plate is located at the top of the first measuring rod when rotating.

[0018] Through the above technical solution, it is possible to prevent sliding between the first measuring rod and the second measuring rod before detection.

[0019] Preferably, the multi-segment structure is divided into a bottom part, an extension part and a top part. The upper and lower ends of the extension part are respectively slidably inserted into the bottom part and the top part through an L-shaped sliding slot and an L-shaped sliding block, and the sliding slot and the sliding block are located on the opposite sides of the first measuring rod and the second measuring rod.

[0020] Preferably, protective sleeves are provided on the outer sides of the multi-segment structure, and the protective sleeves are fixed in cooperation with a plurality of bolts and nuts.

[0021] Through the above technical solution, the lengths of the first measuring rod and the second measuring rod are adjusted in a segmented manner, so as to adapt to the measurement of sewage wells and sewage pipes with different depths, with a wider scope of application, and the first measuring rod and the second measuring rod are extended and connected through the sliding slot and the sliding block.

[0022] The advantages of the present utility model compared with the prior art are as follows:

[0023] 1. This sewage pipe inner diameter measuring device measures the inner diameter of the sewage pipe by setting two relatively long measuring rods, and the two measuring rods respectively abut against the upper and lower sides of the inner diameter of the sewage pipe, and measures the inner diameter of the sewage pipe through the difference above.
