Description

TECHNICAL FIELD

[0001] The utility model relates to underground mine filling technical field especially relates to a monitoring system of pipeline. BACKGROUND

[0002] Underground mine filling technology is a technology that fills solid waste or other materials into a mine after mining is completed. This helps maintain the stability of underground space, reduces the risk of surface subsidence, and reduces the impact on the environment. The filling material can be waste rock, coal gangue, cement or other solid waste. Underground mine filling technology helps improve the safety and sustainability of mines. However, in the application of underground mine filling engineering, there are problems such as pipe blockage and pipe explosion during the transportation of filling slurry. During the slurry transportation process, foreign matter enters the pipeline, slurry segregation and precipitation, insufficient pumping pressure, and slow slurry flow speed can all cause pipe blockage, seriously affecting the filling mining process, and may cause significant economic losses to the entire filling system, and may also pollute the underground environment and be extremely detrimental to the safety of the stope.

[0003] As patent document CN205936696U discloses a filling slurry conveying pipe anti-blocking device, which monitors the pipe wall pressure by setting multiple pressure sensors on the pipeline to monitor pipe blockage. However, it can only determine whether the pipe between the two pressure sensors is blocked, and cannot accurately locate the blockage position. In order to accurately locate the blockage position, multiple pressure sensors need to be arranged on the pipeline, which significantly increases the cost. SUMMARY

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a pipeline blockage position monitoring system that can accurately determine the filling pipeline blockage position and has low cost. To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] In the aforementioned monitoring system, preferably, the pipeline includes a monitoring pipeline and a filling pipeline, with the monitoring pipeline disposed between the filling pipelines, and the monitoring pipeline and the filling pipeline being alternately arranged. A first monitoring component is disposed on the monitoring pipeline, and a second monitoring component is disposed on the filling pipeline. The monitoring pipeline and the filling pipeline are detachably and alternately connected. The first monitoring component is fitted onto the monitoring pipeline and is used to monitor the pressure within the pipeline.

The pressure sensor can directly monitor the pressure inside the pipeline and directly reflect changes in the pressure within the pipeline. The pressure sensor can be any conventional equipment found in the prior art.

[0008] In the aforementioned monitoring system, preferably, the second monitoring component is mounted on the pipe via a sliding component that allows the second monitoring component to be slidably positioned at any location on the outer wall of the pipe. This sliding configuration of the second monitoring component allows for the determination of specific blockage locations on the filling pipe.

[0009] In the aforementioned monitoring system, preferably, the sliding assembly includes a connecting belt and a tensioning element for tightening the connecting belt to make the second monitoring component fit tightly against the outer wall of the pipe or for loosening the connecting belt to make the second monitoring component detach from the outer wall of the pipe. The connecting belt is sleeved on the outside of the pipe, and the second monitoring component is disposed on the connecting belt. The tensioning element can adjust the tightness of the connecting belt, thereby controlling the position of the second monitoring component on the outer wall of the pipe to determine the specific location of the blockage in the filling pipe.

[0010] In the aforementioned monitoring system, preferably, the second monitoring component is a pressure sensor that directly monitors the pressure inside the pipeline.

[0013] In the monitoring system, preferably, a controller is further included, which is electrically connected with the first monitoring component and the second monitoring component, and is configured to determine the blocked position by connecting with the first monitoring component and the second monitoring component.

[0014] Compared with the prior art, the monitoring system has the following advantages:

[0015] The monitoring system for the blocked position of the pipeline can determine whether the pipeline segment between two adjacent first monitoring components is blocked by measuring the pressure difference between the two adjacent first monitoring components.

[0024] The utility model will be further explained in detail in combination with the drawings and specific embodiments of the specification.

[0025] Embodiment 1:

[0026] As shown in the drawings, the pipeline blockage position monitoring system of the embodiment comprises a first monitoring assembly 12 and a second monitoring assembly 14 for monitoring the pressure in the pipeline, the first monitoring assembly 12 is arranged at intervals on the pipeline, the second monitoring assembly 14 is arranged between adjacent first monitoring assemblies 12, and the second monitoring assembly 14 is arranged reciprocatingly on the pipeline. Figures 1-5 In the embodiment, the pipeline comprises a monitoring pipeline 10 and a filling pipeline 11, the monitoring pipeline 10 is arranged between the filling pipeline 11, and the monitoring pipeline 10 and the filling pipeline 11 are arranged alternately, the first monitoring assembly 12 is arranged on the monitoring pipeline 10, and the second monitoring assembly 14 is arranged on the filling pipeline 11.

[0027]

[0028] ​In the embodiment, the monitoring pipeline 10 and the filling pipeline 11 are alternately communicated with each other, and the two are connected through flanges. The filling pipeline 11 is used to transport filling slurry, and the length of the filling pipeline 11 is longer than that of the monitoring pipeline 10 (it can be understood that the monitoring pipeline 10 is a newly added segment for monitoring in the filling pipeline 11). Therefore, in the actual material conveying process, the filling pipeline 11 is prone to blockage, which may cause the pressure in the filling pipeline 11 to increase, thereby reducing the conveying efficiency, and even causing the pipeline to explode. Two monitoring pipelines 10 are arranged at both ends of the filling pipeline 11. In the structure, the internal pressures in the monitoring pipelines 10 at both ends of the filling pipeline 11 are measured by the first monitoring assembly 12, which are P1 and P2 respectively. The difference between P1 and P2 is P3, and the preset pressure difference is P. When P3 reaches the preset pressure difference P, it is determined that the filling pipeline 11 located between the pressure points of P1 and P2 is blocked. At this time, the second monitoring assembly 14 is controlled to move along the extension path of the filling pipeline 11. The second monitoring assembly 14 can monitor the pressure in the filling pipeline 11 at each position in the moving path in real time and obtain the real-time pressure value. In this way, by comparing the size relationship between the real-time pressure, P1 and P2, the blocked position of the filling pipeline 11 can be determined, so as to realize accurate positioning, so as to facilitate subsequent dredging of the filling pipeline 11, ensure normal operation of the material conveying operation, and save costs. The specific value of the preset pressure difference P is obtained through experiments. The parameters and formulas involved in the experiment of the specific value of the preset pressure difference P are well known to those skilled in the art, and are not described here.

[0029] In the embodiment, the first monitoring assembly 12 is a pressure sensor fixedly arranged on the outer wall of the pipeline. The pressure sensor can be directly fixed to the monitoring pipeline 10, which is convenient to assemble and simple to manufacture, and is conducive to saving costs.

[0030] In the embodiment, the second monitoring assembly 14 is arranged on the pipeline through a sliding assembly for slidingly arranging the second monitoring assembly 14 at any position of the outer wall of the pipeline. Specifically, the sliding assembly includes a connecting belt 16 and a tensioning member for tightening the connecting belt 16 to make the second monitoring assembly 14 tightly adhere to the outer wall of the pipeline or loosening the connecting belt 16 to make the second monitoring assembly 14 separate from the outer wall of the pipeline. The connecting belt 16 is sleeved on the outer wall of the pipeline, and the second monitoring assembly 14 is arranged on the connecting belt 16.

[0031] In this embodiment, the connecting belt 16 is movably sleeved on the outer wall of the filling pipeline 11 and detachably connected with the second monitoring assembly 14. The connecting belt 16 is relatively simple to disassemble and assemble, and is convenient for subsequent maintenance and replacement. The connecting belt 16 is also connected with the elastic member and is used to control the tightening of the connecting belt 16 to make the second monitoring assembly 14 tightly adhere to the outer wall of the filling pipeline 11 or control the loosening of the connecting belt 16 to make the second monitoring assembly 14 separate from the outer wall of the filling pipeline 11. After it is determined that the filling pipeline 11 is blocked, the elastic member needs to be controlled to loosen the connecting belt 16, so that the second monitoring assembly 14 separates from the outer wall of the filling pipeline 11, thereby the second monitoring assembly 14 and the connecting belt 16 can be controlled to move along the extension path of the filling pipeline 11, so as to monitor the pressure in the filling pipeline 11 in real time, so as to accurately locate the blocking position of the filling pipeline 11. After the monitoring operation is completed, the elastic member needs to be controlled to tighten the connecting belt 16, so that the second monitoring assembly 14 tightly adheres to the outer wall of the filling pipeline 11, thereby ensuring the stable connection between the second monitoring assembly 14 and the filling pipeline 11. The tightening or loosening of the connecting belt 16 by the elastic member can be realized by manual operation, and in other embodiments, it can also be realized by existing mechanical devices.

[0032] In this embodiment, the second monitoring assembly 14 is a pressure sensor for directly monitoring the pressure in the pipeline. The pressure sensor can be directly fixed to the filling pipeline 11, which is convenient to assemble and simple to manufacture, and is beneficial to save costs.

[0033] In this embodiment, the specific material of the monitoring pipeline 10 is not limited. In some embodiments, the material of the monitoring pipeline 10 is a wear-resistant material, such as an ultra-high molecular weight polyethylene composite material. The monitoring pipeline 10 made of the ultra-high molecular weight polyethylene composite material has better wear resistance and structural strength, and is not easy to be damaged, thereby being beneficial to improve the structural safety and service life of the monitoring device.

[0034] In order to better understand the above scheme, this embodiment also provides a monitoring method for the monitoring system in the foregoing embodiments, and the monitoring method comprises the following steps:

[0035] S1: Obtain the monitoring pressure values P1 and P2 of the two adjacent monitoring pipelines 10, and determine that there is a preset pressure difference P between the two monitoring pressure values. When the pressure difference between the monitoring pipelines 10 connected to the two ends of the same filling pipeline 11 reaches the preset pressure difference P, the filling pipeline 11 is blocked. The specific value of the preset pressure difference P is not limited. The specific value of the preset pressure difference P is obtained through experiments, and the parameters and formulas involved in the experiments related to the specific value of the preset pressure difference P are well known to those skilled in the art.

[0036] S2: controlling the second monitoring assembly 14 to move along the extension path of the filling pipe 11 connected between the two adjacent monitoring pipes 10, and acquiring the real-time pressure value of the filling pipe 11 on the moving path of the second monitoring assembly 14 in real time.

[0037] S3: comparing the real-time pressure and the two monitoring pressure values, and determining the blockage position of the filling pipe 11 according to the comparison result.

[0038] By comparing the size relationship among the real-time pressure, P1 and P2, the blockage position of the filling pipe 11 can be determined, so that accurate positioning is realized, so that the filling pipe 11 is dredged subsequently, the material conveying operation is ensured to be carried out normally, and cost is saved.

[0039] Embodiment 2:

[0040] Compared with embodiment 1, the main difference of the embodiment is that the second monitoring assembly 14 is an extensometer for monitoring the deformation of the pipe to indirectly monitor the pressure in the pipe, and the others are the same as those in embodiment 1.

[0041] The extensometer has good sensitivity, and by connecting the extensometer to the outer wall of the filling pipe 11, the pressure-related values in the filling pipe 11 can be accurately and timely acquired, so that the blockage position of the filling pipe 11 can be accurately positioned, and the extensometer has simple assembly and convenient installation, which is beneficial to save time and cost. The specific way of connecting the extensometer to the outer wall of the filling pipe 11 is not limited, and the installation method in embodiment 1 can be used.

[0042] Although the present application has been disclosed with the above preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make many possible changes and modifications to the technical solutions of the present application, or modify equivalent embodiments with equivalent changes, without departing from the scope of the technical solutions of the present application.
