Description

Technical Field

[0001] The utility model belongs to the technical field of transportation safety monitoring and relates to a transportation pipeline blockage monitoring device. Background Art

[0002] When using a material conveying device to transport materials, if the material is mixed with large pieces of material or the material is wet or arched and blocked, if it is not detected in time, it will cause material accumulation and affect the transportation process. Traditional material conveying devices use manual detection to identify blockages, such as observing whether there is squeezing or overflow at the feed port, whether there is no material discharged from the discharge port for a long time, etc. However, due to the lack of timely manual detection, it is easy to cause serious damage to the equipment. In order to quickly detect blockage problems, material conveying devices began to set up detection switches instead of manual identification. However, the detection switches of existing material conveying devices are prone to false alarms, and the detection accuracy is low. In addition, the detection switches are installed at high places, making disassembly and cleaning very troublesome, posing a safety hazard, resulting in a long processing time, affecting production progress. In addition, the existing detection switches can only detect blockages, and it is difficult to confirm the specific location of the blockage. It is also necessary to arrange for special personnel to clean it continuously, or even cut the pipeline for processing, resulting in unpredictable serious consequences.

[0003] Therefore, it is very important to further improve the detection accuracy of material conveying devices and determine the location of blockages for safe production and transportation. Utility Model Content

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0028] It should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] Those skilled in the art should understand that the present invention necessarily includes necessary pipelines, conventional valves and general pump equipment for realizing a complete process, but the above content does not constitute the main improvement of the present invention. Those skilled in the art can add layouts on their own based on the process flow and equipment structure selection, and the present invention does not make special requirements or specific limitations on this.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] In a specific embodiment, the present invention provides a pipeline blockage monitoring device, such as Figure 1 As shown, it includes a pipeline body 1, a monitoring terminal 2, a blockage detection component and several vibration monitoring components 3. Figure 2 As shown, the blockage detection component includes a detection shell 4, on which a connecting cavity 5 is provided, and the connecting cavity 5 is connected to the pipeline body 1. A detection part 6 is provided in the detection shell 4, and the detection part 6 is used to detect the blockage situation in the pipeline body 1. Several vibration monitoring components 3 are arranged at intervals along the length direction of the pipeline body 1 to accurately locate the blockage part. This is because when the conveying pipeline is blocked, the pipe section from its inlet end to the blocked part will vibrate strongly, while the pipe section behind the blocked part is relatively quiet. By obtaining the vibration state of the pipe section detected by multiple vibration monitoring components 3, the specific location of the blocked part can be determined. The monitoring terminal 2 is respectively connected to the blockage detection component and the vibration monitoring component 3 for communication. The monitoring terminal 2 serves as a terminal for operation and monitoring by operation and maintenance personnel in the coal mine, so as to stop the transportation according to the blockage situation and perform dredging based on the specific location of the blocked part.

[0032] The monitoring terminal 2 of the present invention can correspond to blockage detection components on multiple different pipeline bodies 1, enabling centralized operation and monitoring of complex pipeline systems. Furthermore, multiple blockage detection components can be installed on the same pipeline body 1, each independently communicating with the monitoring terminal 2 to enable segmented blockage monitoring of different pipe sections.

[0033] In some embodiments, a connecting flange 7 is provided at one end of the connecting cavity 5 away from the detection shell 4. The connecting flange 7 can be detachably connected to the pipeline body 1. During application, the detection shell 4 is installed, disassembled, cleaned and maintained at the connecting flange 7, which is convenient to operate and can also avoid damage to the equipment.

[0034] Furthermore, the dust and small particles generated by the pipeline main body 1 during the material transportation process can easily enter the interior of the connecting cavity 5 and affect the detection process. The utility model opens an airflow cleaning hole 8 on the connecting cavity 5. Since the internal pressure of the connecting cavity 5 is lower than the atmospheric pressure, the atmosphere outside the cavity enters the interior of the connecting cavity 5 through the airflow cleaning hole 8, thereby automatically cleaning the dust in the cavity.

[0035] Furthermore, the blockage detection assembly further includes a cleaning unit, such as Figure 3 As shown, the cleaning unit includes a drive member 9 and a cleaning ring 10 that are connected in a transmission manner. The cleaning ring 10 is arranged circumferentially along the inner wall of the connecting cavity 5. The outer wall of the cleaning ring 10 is provided with a cleaning brush. The drive member 9 is fixed in the detection housing 4 and is used to drive the cleaning ring 10 to move axially along the connecting cavity 5. The drive member 9 must include a servo motor and a telescopic rod for achieving a complete process, so that one end of the telescopic rod is connected to the servo motor and the other end is connected to the cleaning ring 10. The servo motor drives the telescopic rod to perform a telescopic movement, thereby driving the cleaning ring 10 to reciprocate in the connecting cavity 5 to clean the sediment into the pipeline body 1, ensuring the smooth flow and cleanliness of the connecting cavity 5. In addition, the monitoring terminal 2 can also realize remote control of the servo motor through common software, hardware and electromechanical control technology in this field to automatically clean the connecting cavity 5 at a regular interval.

[0036] In some embodiments, the detection unit 6 is any one of a photoelectric sensor, a pressure switch, or a proximity switch.

[0037] Furthermore, an adjustment bracket 11 is provided in the detection housing 4, and the detection unit 6 is fixed on the adjustment bracket 11. In order to help those skilled in the art better understand the overall technical solution and working process of the present invention, the present invention exemplarily provides the following specific arrangements and detection principles of the detection unit 6.

[0038] Option 1: When the detection unit 6 employs a photoelectric sensor, it specifically comprises a light emitting unit and a light receiving unit spaced apart on the adjustment bracket 11. Light emitted by the light emitting unit passes through the connecting cavity 5 and enters the pipe body 1. After reflection, it is received by the light receiving unit. When the pipe body 1 is unobstructed, the light receiving unit receives a preset light energy signal. However, when the pipe body 1 is obstructed, the light energy signal received by the light receiving unit changes, and a blockage signal is output to the monitoring terminal 2.

[0039] Option 2: When the detection unit 6 uses a pressure switch, the pressure switch is fixed to the adjustment bracket 11 and corresponds to the connecting channel 5. At the same time, the connecting channel 5 is provided with necessary pressure components, including a drive block, a stopper, a return spring, and a push rod. The stopper is fixed inside the connecting channel 5. The drive block is set on the side of the stopper close to the pipe body 1 and is connected to the stopper via a return spring. The drive block is slidable along the connecting channel 5. One end of the push rod is connected to the drive block, and the other end passes through the stopper to contact the pressure switch. When there is no blockage inside the pipe body 1, the drive block remains in its original state, the push rod does not touch the proximity switch, and the pressure switch is in the off state. When a blockage occurs inside the pipe body 1, the material inside the pipe body 1 presses the drive block, causing the drive block to move toward the side close to the stopper, thereby driving the push rod to contact the pressure switch, energizing the pressure switch and outputting a signal to the monitoring terminal 2.

[0040] Option 3: When the detection unit 6 uses a proximity switch, the proximity switch is fixed to the adjustment bracket 11 and corresponds to the connecting cavity 5. At the same time, the connecting cavity 5 is provided with a trigger member necessary for triggering the proximity switch. The trigger member includes a connecting rod, a trigger rod, and a contact piece. One end of the connecting rod is movably connected to the adjustment bracket 11, and the other end is connected to the contact piece. The contact piece is located at the junction of the connecting cavity 5 and the pipeline body 1. One end of the trigger rod is fixed to the contact piece, and the other end is spaced apart from the proximity switch. When there is no blockage in the pipeline body 1, the trigger rod will not touch the proximity switch, and the proximity switch is in the off state. However, when there is a blockage in the pipeline body 1, the material in the pipeline body 1 presses the contact piece, causing the trigger rod to approach and contact the proximity switch, closing the contacts of the proximity switch and outputting a signal to the monitoring terminal 2.

[0041] It should be noted that the detection unit 6 is also provided with necessary connecting pipes and switch control valves. The present invention does not make special restrictions on this. Those skilled in the art need to make reasonable adjustments, additions or deletions according to actual production needs. It should be clear that new technical solutions generated by deleting some unnecessary connecting pipes and switch control valves, or replacing single-function switch control valves with multi-function integrated control valves, or using an automatic control system in which an external device is electrically connected to the switch control valve to control the opening of the corresponding valve, etc., which are common and well-known conventional technical means for those skilled in the art, also fall within the scope of disclosure and protection of the present invention.

[0042] In some embodiments, the vibration monitoring component 3 includes an ultrasonic vibration sensor. When a blockage occurs, the section of the pipeline from the inlet to the blocked area will vibrate strongly, while the section behind the blocked area will be relatively quiet. By detecting the vibration state of the pipe section with the ultrasonic vibration sensor and analyzing the vibrations of multiple different pipe sections, the specific location of the blockage can be accurately determined, allowing timely unblocking work.

[0043] In some embodiments, the monitoring terminal 2 includes a remote host computer, a visual display screen and an alarm. The remote host computer is electrically connected to the visual display screen and the alarm, and the remote host computer is also communicatively connected to the blockage detection component and the vibration monitoring component 3. The remote host computer stops the conveying operation according to the blockage situation, and sends out a blockage warning signal at the same time, and performs a dredging action based on the specific location of the blockage part, and resumes the conveying operation after the dredging is completed. The visual display screen can intuitively display the data information obtained by the blockage detection component and the vibration monitoring component 3 to the operation and maintenance personnel. The alarm issues an alarm prompt when a blockage occurs in the pipeline main body 1. The utility model can dynamically monitor the pipeline transportation situation in real time. Once a blockage is found, it can alarm in the first time and stop the operation of related equipment, which has the advantages of being timely, fast and efficient.

[0044] Furthermore, the alarm includes an indicator light and a buzzer.

[0045] Furthermore, the blockage detection component is connected to the remote host computer via a signal power supply wire, and the vibration monitoring component 3 is wirelessly connected to the remote host computer.

[0046] The applicant declares that the above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Technicians in the relevant technical field should understand that any changes or substitutions that can be easily thought of by technicians in the relevant technical field within the technical scope disclosed in the present invention fall within the protection scope and disclosure scope of the present invention.
