Description
Technical Field
[0001] This utility model belongs to the field of pipeline measurement technology, and in particular relates to a pipeline measurement device. Background Technology
[0002] Pipeline surveys require measuring and recording pipe diameter and well depth data. In practice, well depth is typically measured using a leveling rod or steel tape measure, a cumbersome process. The presence of silt at the bottom of the well can introduce errors, and different well depths necessitate the use of different measuring tools. Precise measurements require entry into the manhole, which is a confined space. Entry into confined spaces demands rigorous training and safety education, and involves complex procedures such as ventilation, toxic gas detection, and work permits, resulting in lengthy preparation times and significantly reduced efficiency.
[0003] Therefore, there is an urgent need to design a pipeline measurement device that can quickly and accurately measure the depth of underground wells from the ground to solve the problems mentioned above. Utility Model Content
[0004] The purpose of this invention is to provide a pipeline measuring device that has the advantage of being able to quickly and accurately measure the depth of underground pipeline wells on the ground, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, the specific technical solution of this application is as follows:
[0006] A pipeline measuring device includes a probe and a mud-trapping rod;
[0007] One end of the probe is for personnel on the ground to hold. A collar is horizontally connected to the probe, and a mud-binding rod is connected to the collar. The mud-binding rod can slide relative to the collar along the well depth direction. The mud-binding rod is used to contact the bottom surface of the pipeline. The distance from the contact point between the mud-binding rod and the bottom surface of the pipeline to the top of the collar is the first distance. The distance from the top of the collar to the position of the probe parallel to the ground is the second distance. The sum of the first distance and the second distance is the well depth.
[0008] Furthermore, the bottom end of the mud-binding rod is connected to a sharp end, and the mud-binding rod penetrates the accumulated mud at the bottom of the pipe through the sharp end to contact the ground of the pipe.
[0009] Furthermore, both the probe rod and the mud-binding rod are engraved with length markings. The starting point of the length markings on the probe rod is on the same horizontal line as the top of the collar, and the starting point of the length markings on the mud-binding rod is located at the end of the sharp tip.
[0010] Furthermore, the first distance is the distance from the starting point of the length scale on the mud-binding rod to the top of the collar, and the second distance is the distance from the starting point of the length scale on the probe rod to the position where the probe rod is parallel to the ground.

[0013] Furthermore, the connecting rod is equipped with a control component, which is used to adjust the connection and fixation between the mud-binding rod and the probe rod.
[0014] Furthermore, the control component includes an electric push rod, the output end of which has anti-slip texture, and the mud-binding rod has a groove along its height direction, the groove having anti-slip texture.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.
[0027] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This invention describes a pipe measuring device.
[0028] The inspection well 4 includes an internally hollow pipe 41 and an internally hollow well body 42. The pipe 41 is connected to the well body 42. The pipe measuring device needs to pass through the well body 42 to measure the depth of the pipe 41 (i.e., the well depth).
[0029] Currently, to conduct accurate measurements, it is necessary to enter the inspection well 4. However, the drainage inspection well 4 is a confined space. Entering a confined space requires strict training and safety education, and the operation procedures are complicated. Ventilation, toxic gas detection, and work approval are required before entry is permitted. This process is time-consuming and carries high safety risks.
[0030] Therefore, this embodiment provides a pipeline measurement device, including a probe 1. One end (i.e., the upper end) of the probe 1 is held by personnel on the ground, and the end of the probe 1 away from the personnel holding it (i.e., the lower end) is connected to a quantization component 2. The personnel on the ground move the quantization component 2 along the well depth direction to the center line of the pipeline 41 through the probe 1, and collect images inside the pipeline 41 through the quantization component 2. A collar 12 is connected to the probe 1, and a mud-binding rod 3 is provided on the collar 12. The mud-binding rod 3 can slide relative to the collar 12 along the well depth direction. The mud-binding rod 3 can contact the bottom surface of the pipeline. When the mud-binding rod 3 contacts the bottom surface of the pipeline, the distance from the connection point of the mud-binding rod 3 to the bottom of the pipe to the top of the collar 12 is the first distance A, and the distance from the position of the probe 1 parallel to the ground to the top of the collar 12 is the second distance B. The sum of the first distance A and the second distance B is the well depth dimension.
[0031] This pipeline measurement device eliminates the need for surveyors to go down into the well; they can operate and measure from the ground. It requires little preparation time and poses no safety hazards. Furthermore, each measurement taken in the well using this device can complete the well depth measurement and the acquisition of images inside the pipeline, thus improving measurement efficiency.
[0032] Considering the potential for sludge buildup at the bottom of the pipe to affect the accuracy of height measurement, in this embodiment, preferably, a sharp end is connected to the bottom of the mud-binding rod 3. The sharp end and the mud-binding rod 3 can be an integral structure or connected by a threaded connection, facilitating the replacement of the worn-out sharp end after long-term use. The mud-binding rod 3 can directly penetrate the accumulated sludge at the bottom of the pipe through the sharp end, thereby ensuring that the sharp end contacts the bottom surface of the pipe 41 and guaranteeing accurate measurement of the well depth.
[0033] Both the probe rod 1 and the mud-binding rod 3 are engraved with length scales. The starting point of the length scale on the probe rod 1 is on the same horizontal line as the top of the collar 12. The starting point of the length scale on the mud-binding rod 3 is located at the bottom of the sharp end. After the sharp end penetrates the mud at the bottom of the pipe, the end of the sharp end contacts the bottom surface of the pipe 41. That is, the starting point of the length scale on the mud-binding rod 3 contacts the bottom surface of the pipe 41, which ensures the accuracy of the well depth measurement.
[0034] In this embodiment, the second distance B is the distance from the starting point of the length scale on the probe rod 1 to the position where the probe rod 1 is parallel to the ground, the first distance A is the distance from the starting point of the length scale on the mud-binding rod 3 to the top of the collar 12, and the sum of the first distance A and the second distance B is the well depth distance.
[0035] The mud-binding rod 3 is slidably connected in the through hole of the collar 12, so that the mud-binding rod 3 can only slide along the well depth direction; a connecting rod 11 is fixedly connected to the probe rod 1, the connecting rod is arranged laterally relative to the probe rod 1, and the end of the connecting rod 11 away from the probe rod 1 is fixedly connected to the collar 12.
[0036] The connecting rod 11 is equipped with a control component, which controls whether the mud-binding rod 3 is connected and fixed to the probe rod 1. Specifically, the control component includes an electric push rod 13, the output end of which has anti-slip texture, and the mud-binding rod 3 has a groove 31 with anti-slip texture inside.
[0037] After the mud-piercing rod 3 penetrates the mud at the bottom of the pipe, the anti-slip pattern at the output end of the electric push rod 13 is controlled to abut against the anti-slip pattern of the groove 31, and the mud-piercing rod 3 is connected and fixed to the probe rod 1. This prevents the mud-piercing rod 3 from sliding relative to the probe rod 1 when it is inserted into the mud at the bottom of the pipe, thus preventing it from penetrating the mud at the bottom of the pipe.
[0038] After the mud-piercing rod 3 penetrates the mud at the bottom of the pipe, when the quantification component 2 is moved to the center line position of the pipe 41, the anti-slip pattern at the output end of the electric push rod 13 is separated from the anti-slip pattern of the groove 31, and the probe rod 1 can slide relative to the mud-piercing rod 3. Thus, the probe rod 1 and the quantification component 2 slide relative to the mud-piercing rod 3 until the quantification component 2 slides to the center line area of the pipe 41.
[0039] In this embodiment, the electric linear actuator can be connected to a power source and controller on the ground via a wire, making it easy for operators to control. The electric linear actuator can also be a product with its own battery, which can be controlled by connecting to the controller via a wire or wireless module.
[0040] After the quantizing component 2 moves to the center line of the pipe 41, when the quantizing component 2 measures the diameter of the pipe 41, the anti-slip texture of the output end of the electric push rod 13 abuts against the anti-slip texture of the groove 31, and the mud-binding rod 3 is connected and fixed to the probe rod 1, so as to prevent the quantizing component 2 and the probe rod 1 from still sliding and affecting the measurement results.
[0041] In this embodiment, a placement groove 14 is provided on the connecting rod 11. The placement groove 14 is fixedly connected to the electric push rod 13. The output end of the electric push rod 13 passes through the collar 12 and extends into the collar 12.
[0042] The quantization component 2 includes a camera 21 and a quantization module 22. The camera 21 is electrically connected to a wireless video recorder located on the ground. Personnel on the ground observe the center position of the pipe 41 through the camera 21. When the center point of the video from the wireless video recorder is at the center position of the pipe 41, the camera 21 is located on the center line of the pipe 41. The quantization module 22 is integrated into the bottom of the housing of the camera 21 and is electrically connected to the camera 21. The quantization module 22 acquires the video image information inside the pipe 41 collected by the camera 21, which is convenient for subsequent measurement of the pipe diameter.
[0043] The method of using the pipeline measuring device provided in this embodiment is as follows:
[0044] The length of the mud-binding rod 3 is estimated and adjusted in advance based on the diameter of the pipe 41. The anti-slip pattern at the output end of the electric push rod 13 is controlled to abut against the anti-slip pattern of the groove 31. The mud-binding rod 3 is then connected and fixed to the probe rod 1.
[0045] Adjust the position to keep the quantization component 2 at the center of the well body 42, and then lower it along the center of the well body 42 until the mud-binding rod 3 penetrates the mud at the bottom of the pipe. Control the anti-slip pattern of the output end of the electric push rod 13 to separate from the anti-slip pattern of the groove 31. The probe rod 1 can slide relative to the mud-binding rod 3. The ground personnel observe the center position of the pipe 41 through the camera 21. When the video center point of the wireless video device is at the center position of the pipe 41, the anti-slip pattern of the output end of the electric push rod 13 abuts against the anti-slip pattern of the groove 31. The mud-binding rod 3 is connected and fixed to the probe rod 1 to keep the equipment stable and record the first distance A. Observe the second distance B from the parallel position on the ground. The sum of the first distance A and the second distance B is the actual well depth measurement data. Turn on the quantization module 22 and obtain the video image data inside the pipe to facilitate the subsequent calculation of the actual pipe diameter data.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
