技术领域technical field

本发明涉及一种管道检测装置和疏通方法,具体涉及一种外露充填管道堵塞便携检测装置及疏通方法,属于外露型充填管道堵塞检测与疏通技术领域。The invention relates to a pipeline detection device and a dredging method, in particular to a portable detection device and a dredging method for blockage of an exposed filling pipeline, belonging to the technical field of blockage detection and dredging of an exposed filling pipeline.

背景技术Background technique

充填开采相比于传统开采方式具有诸如减少矸石外排、避免像传统开采那般引起地表变形与沉陷、地下水流失以及实现低贫损开采的优点,是一种环境友好型与远景资源节约型的煤炭开采方式。Compared with traditional mining, backfill mining has the advantages of reducing gangue efflux, avoiding surface deformation and subsidence, groundwater loss and realizing low-loss mining like traditional mining. It is an environment-friendly and prospective resource-saving mining method. Coal mining method.

但在充填系统的运行过程中,最突出的缺陷在于充填效率跟不上资源开采效率,导致充填开采效率低。充填效率低的原因除了充填材料本身,如膏、胶体充填材料在充填后的硬化需要一定的时间外,充填管道堵塞是另一降低充填效率的重要因素,充填管道堵塞不仅会引起施工中断,寻找、疏通堵塞点费时费力,而且会在一定程度上限制充填材料的输送速度。However, during the operation of the filling system, the most prominent defect is that the filling efficiency cannot keep up with the resource extraction efficiency, resulting in low filling and extraction efficiency. The reasons for the low filling efficiency are not only that the filling materials themselves, such as paste and colloid filling materials, take a certain amount of time to harden after filling, and the blockage of the filling pipeline is another important factor that reduces the filling efficiency. , Unclogging the blocked point is time-consuming and labor-intensive, and will limit the conveying speed of the filling material to a certain extent.

常用的堵塞部位寻找方法包括分段拆管法、压力监测法,对于短距离的充填管道来说还具备实施的可能性,但也需要克服诸多困难,对于长距离的充填材料运输管道来说,这些方法实施起来则会更加的困难,且大大增加了运营成本,因而针对膏体、胶体等外露充填管道的堵塞问题,目前并没有可靠、简便的检测装置以及快速高效的疏通方法对此加以解决。Commonly used methods for finding blocked parts include pipe dismantling method and pressure monitoring method. For short-distance filling pipelines, it is still possible to implement, but many difficulties need to be overcome.

一种外露充填管道堵塞疏通方法,包括如下步骤:A method for blocking and dredging an exposed filling pipeline, comprising the following steps:

模拟各类特定充填材料所充填的管道内的流通环境,利用共振法,启动超声波变频振动组件进行超声波的形成,同时启动超声波振动测试组件进行超声波的接收和显示,得到引起管道内流体共振的激发频率并进行记录;Simulate the circulation environment in the pipeline filled with various specific filling materials, use the resonance method to start the ultrasonic frequency conversion vibration component to form ultrasonic waves, and start the ultrasonic vibration test component to receive and display ultrasonic waves to obtain the excitation that causes the fluid resonance in the pipeline. frequency and record;

管道内流体在检测装置的激发频率的作用下产生共振,共振信号被超声波接收探头捕捉经测量传感器转换后传送至控制器,显示屏上实时显示出振幅较大且稳定的波谱或振幅数字信号;The fluid in the pipeline resonates under the action of the excitation frequency of the detection device. The resonance signal is captured by the ultrasonic receiving probe, converted by the measurement sensor, and sent to the controller. The display screen displays a large and stable spectrum or amplitude digital signal in real time;

继续移动便携检测装置,当显示屏上的波谱或振幅数字信号开始出现明显变化,即振幅不再稳定且振幅减小时,说明被检测部位的管道内材质不再是流体,而是引发堵塞的固体,继续移动扫描,直至显示屏上再次出现振幅较大且稳定的波谱或振幅数字信号,即可判定这两段振幅较大且稳定的波谱信号之间的部分为堵塞位置;Continue to move the portable detection device.

进一步地,所述的步骤(2)和步骤(3)中,为减小超声波接收探头和超声波共振触头与管道外壁之间的阻力,使用前对超声波接收探头和超声波共振触头做润滑处理。Further, in the described step (2) and step (3), in order to reduce the resistance between the ultrasonic receiving probe and the ultrasonic resonance contact and the outer wall of the pipeline, the ultrasonic receiving probe and the ultrasonic resonance contact are lubricated before use. .

本疏通方法通过利用声波在不同介质中传播时频率不变的原理,通过收集参照数据并利用相应的参照频率进行检测,从而判定堵塞位置,利用共振法启动检测装置中的超声波共振触头对堵塞位置的固体进行疏松破碎,在对原管道系统不产生任何破坏的前提下,实现了对管道快速高效的疏通。This dredging method uses the principle that the frequency of sound waves does not change when propagating in different media, collects reference data and uses the corresponding reference frequency for detection, so as to determine the blockage position, and uses the resonance method to activate the ultrasonic resonance contact in the detection device to correct the blockage. The solids at the location are loosely broken, and the pipeline can be dredged quickly and efficiently without any damage to the original pipeline system.

When the spectrum or amplitude digital signal on the display screen 8 begins to change, that is, when the amplitude is no longer stable and the amplitude decreases, it means that the material in the pipeline 2 of the detected part is no longer fluid, but causes blockage. solid, continue to move and scan until the large and stable spectrum or amplitude digital signal appears again on the display screen 8, then it can be determined that the part between these two large and stable spectrum signals is the blockage position;

(3)疏通堵塞:对步骤(2)中确定的堵塞位置,利用步骤(1)得出的相应充填材料固化后的共振频率,启动超声波变频振动组件和超声波振动测试组件,调整超声波共振触头6的超声波频率与充填材料固化后的共振频率一致后,对堵塞位置的管道2外壁进行持续扫描,使管道2内固体疏松破碎,破碎的固体被管道2内流体不断冲散,直至管道2疏通。(3) Clear the blockage: For the blockage position determined in step (2), use the resonance frequency of the corresponding filling material obtained in step (1) after curing, start the ultrasonic frequency conversion vibration component and the ultrasonic vibration test component, and adjust the ultrasonic resonance contact. After the ultrasonic frequency of 6 is consistent with the resonant frequency of the filling material after curing, continuously scan the outer wall of the pipeline 2 at the blocked position, so that the solid in the pipeline 2 is loose and broken, and the broken solid is continuously dispersed by the fluid in the pipeline 2 until the pipeline 2 is dredged. .

如图3所示,在超声波激励共振状态下,堵塞体被疏松并开始出现破碎,堵塞体尺寸开始变小;如图4所示,在共振及堵塞体两旁管道2压差的共同作用下,管道2疏通;如图5所示,破碎后的小尺寸块体在管道内流体冲动下被松散一同向出口方向运动,最终完成管道2的完全疏通。As shown in Figure 3, in the state of ultrasonic excitation resonance, the blocking body is loosened and begins to break, and the size of the blocking body begins to decrease; Pipeline 2 is dredged; as shown in Figure 5, the broken small-sized blocks are loosened under the impulse of fluid in the pipeline and move together toward the outlet, and finally complete the complete dredging of pipeline 2.

为获得最佳的疏通效果,超声波共振触头6与管道2外壁进行接触疏通。In order to obtain the best dredging effect, the ultrasonic resonant contact 6 is in contact with the outer wall of the pipeline 2 to dredge.

为减小超声波接收探头5和超声波共振触头6与管道2外壁之间的阻力,步骤(2)和步骤(3)中,使用前对超声波接收探头5和超声波共振触头6做润滑处理。In order to reduce the resistance between the ultrasonic receiving probe 5 and the ultrasonic resonance contact 6 and the outer wall of the pipeline 2, in steps (2) and (3), the ultrasonic receiving probe 5 and the ultrasonic resonance contact 6 are lubricated before use.

超声波接收探头5和超声波共振触头6可根据实际的频率需要进行数量及位置的调整,超声波接收探头5和超声波共振触头6距离管道2的距离可通过旋深或旋浅在开口环螺纹安装孔4内的深度进行调整。The ultrasonic receiving probe 5 and the ultrasonic resonance contact 6 can be adjusted in quantity and position according to the actual frequency. The distance between the ultrasonic receiving probe 5 and the ultrasonic resonance contact 6 from the pipe 2 can be installed on the split ring thread by turning deep or shallow. The depth inside the hole 4 is adjusted.

本疏通方法通过利用声波在不同介质中传播时频率不变的原理,通过收集参照数据从而判定堵塞位置,并利用共振法启动检测装置中的超声波共振触头对堵塞位置的固体进行疏松破碎,在对原管道系统不产生任何破坏的前提下,实现了对管道快速高效的疏通。This dredging method uses the principle that the frequency of sound waves does not change in different media, collects reference data to determine the blockage position, and uses the resonance method to start the ultrasonic resonance contact in the detection device to loosen and break the solid in the blockage position. On the premise of no damage to the original pipeline system, the pipeline can be dredged quickly and efficiently.
