Description

Technical Field

[0001] This application relates to the field of sampling technology and equipment, and in particular to an intelligent sampler monitoring system. Background Technology

[0002] Coal quality testing requires coal sampling. In this process, the sampler, as the first sampling device in the entire mechanical sampling system, determines the overall accuracy of the system. Furthermore, as the only device directly connected to the coal conveyor belt, its stable operation not only affects the stability of the entire mechanical sampling system but also directly impacts the normal operation of the main conveyor belt and production safety. If the sampler malfunctions, especially if its cutter remains on the coal flow for an extended period, it can lead to sampling interruptions, coal sample accumulation, and damage to the conveyor belt. Even without these malfunctions, prolonged contact of the cutter outside the coal flow cutting area indicates an abnormal operating condition. Current technologies rely solely on manual observation of the sampler's operation, which is inefficient, inefficient, and prone to errors. Utility Model Content

[0003] The purpose of this application is to propose an intelligent sampler monitoring system that can quickly make judgments and issue warnings, thereby effectively avoiding abnormal sampling operations caused by sampler 1 equipment failure.

[0004] To achieve the above objectives, the first aspect of this application proposes an intelligent sampler monitoring system applied above a coal conveyor belt 3. The system includes a sampler 1, an angle sensor 2, a zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, a fourth position area 8, and a PLC controller, wherein:

[0005] An angle sensor 2 is provided on the sampler 1 to monitor the rotation angle of the sampler 1, and a zero-degree line 4 is provided, which is the zero-degree line of the angle sensor 2.

[0006] Based on the zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, and a fourth position area 8 are set in the cross-sectional area between the sampler 1 and the coal conveyor belt 3. The first position area 5 is an area with an angle greater than 0 degrees and less than 60 degrees. The second position area 6 is an area with an angle greater than or equal to 60 degrees and less than or equal to 90 degrees. The third position area 7 is an area with an angle greater than 90 degrees and less than 220 degrees. The fourth position area 8 is an area with an angle greater than 220 degrees and less than 360 degrees.

[0007] The PLC controller is used to monitor the dwell time of the sampler 1 in the first position area 5, the second position area 6, the third position area 7, and the fourth position area 8, respectively, so as to determine the operating status of the sampler 1 and output signals.

[0008] The sampler 1 rotates approximately around the center of the coal conveyor belt 3 to collect coal samples transported on the conveyor belt 3.

[0009] In addition, the intelligent sampler monitoring system proposed in this application may also have the following additional technical features:

[0010] In some embodiments, when the sampler 1 is not taking coal samples, the sampler 1 normally stops in the second position area 6. When the sampler 1 takes coal samples, a sampling signal is issued, the sampler 1 rotates clockwise, passes through the third position area 7 and enters the fourth position area 8, cuts and scrapes the coal sample on the coal conveyor belt 3, continues to rotate under inertia, passes through the first position area 5, and stops in the second position area 6.

[0011] This application discloses an intelligent sampler monitoring system, which is applied above a coal conveyor belt 3. The system includes a sampler 1, an angle sensor 2, a zero-degree line 4, a first position zone 5, a second position zone 6, a third position zone 7, a fourth position zone 8, and a PLC controller. The angle sensor 2 is installed on the sampler 1 to monitor its rotation angle. A zero-degree line 4 is set. The system includes a first position zone 5 with an angle greater than 0 degrees and less than 60 degrees, a second position zone 6 with an angle greater than or equal to 60 degrees and less than or equal to 90 degrees, a third position zone 7 with an angle greater than 90 degrees and less than 220 degrees, and a fourth position zone 8 with an angle greater than 220 degrees and less than 360 degrees. The PLC is used to determine the operating status of the sampler 1 based on its dwell time in each position zone, and can quickly make judgments and issue warning signals, thereby effectively avoiding abnormal sampling operations caused by sampler 1 equipment failure.

[0012] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0013] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein:

[0014] Figure 1 This is a schematic diagram of the structure of an intelligent sampler monitoring system provided in an embodiment of this application. Detailed Implementation

[0015] The embodiments of this application are described in detail below, with examples of the embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0016] The intelligent sampler monitoring system of this application is described below with reference to the accompanying drawings.

[0017] Figure 1 This is a structural diagram of an intelligent sampler monitoring system according to an embodiment of this application.

[0018] like Figure 1 As shown in the figure, the intelligent sampler monitoring system of this application monitors the operation of the sampler above the coal conveyor belt 3. The system includes a sampler 1, an angle sensor 2, a zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, a fourth position area 8, and a PLC controller (not shown in the figure), wherein:

[0019] An angle sensor 2 is installed on the sampler 1 to monitor the rotation angle of the sampler 1, and a zero-degree line 4 is set, which is the zero-degree line of the angle sensor 2.

[0020] Based on the zero-degree line 4, a first position area 5, a second position area 6, a third position area 7, and a fourth position area 8 are set in the cross-sectional area between the sampler 1 and the coal conveyor belt 3. The first position area 5 is an area with an angle greater than 0 degrees and less than 60 degrees, the second position area 6 is an area with an angle greater than or equal to 60 degrees and less than or equal to 90 degrees, the third position area 7 is an area with an angle greater than 90 degrees and less than 220 degrees, and the fourth position area 8 is an area with an angle greater than 220 degrees and less than 360 degrees.

[0021] The PLC controller is used to monitor the dwell time of the sampler 1 in the first position area 5, the second position area 6, the third position area 7, and the fourth position area 8, respectively, so as to determine the operating status of the sampler 1 and output signals.

[0022] Sampler 1 rotates around the approximate center of the coal conveyor belt 3 to collect coal samples transported on the coal conveyor belt 3.

[0023] In some embodiments, sampler 1 is used in the coal sampling process. The purpose of coal sampling is to obtain a test coal sample whose test results are representative of the entire batch of sampled coal. The basic process of coal sampling is to first collect a considerable amount of coal, i.e., a primary sample, from many points distributed throughout the batch of coal. Then, the primary samples are directly merged or reduced and merged into a total sample. Finally, this total sample is processed through a series of sample preparation procedures to produce the required number and type of test coal samples, which are used for coal quality testing. This allows for effective monitoring of the operating status of sampler 1. If the sampler remains on the conveyor belt (fourth position zone 8) for a certain period of time, or remains outside the conveyor belt cutting area (first position zone 5 or third position zone 7) for too long, a quick judgment and warning can be issued. This effectively avoids accidents such as sampling interruption, coal sample accumulation, and conveyor belt damage caused by sampler 1 malfunction. It also provides early warning of abnormal operating conditions of sampler 1, ensuring maintenance prompts before equipment accidents occur and preventing larger accidents.

[0024] Furthermore, when the sampler 1 is not taking coal samples, the sampler 1 normally stops in the second position zone 6. When the sampler 1 takes coal samples, a sampling signal is issued, the sampler 1 rotates clockwise, passes through the third position zone 7 and enters the fourth position zone 8, cuts and scrapes the coal sample on the coal conveyor belt 3, continues to rotate under the action of inertia, passes through the first position zone 5, and stops in the second position zone 6.

[0025] This application discloses an intelligent sampler monitoring system, which is applied above a coal conveyor belt 3. The system includes a sampler 1, an angle sensor 2, a zero-degree line 4, a first position zone 5, a second position zone 6, a third position zone 7, a fourth position zone 8, and a PLC controller. The angle sensor 2 is installed on the sampler 1 to monitor its rotation angle. A zero-degree line 4 is set. The system includes a first position zone 5 with an angle greater than 0 degrees and less than 60 degrees, a second position zone 6 with an angle greater than or equal to 60 degrees and less than or equal to 90 degrees, a third position zone 7 with an angle greater than 90 degrees and less than 220 degrees, and a fourth position zone 8 with an angle greater than 220 degrees and less than 360 degrees. The PLC controller monitors the dwell time of the sampler 1 in each of the first, second, third, and fourth position zones, thereby determining the operating status of the sampler 1 and issuing timely warnings based on the judgment, effectively preventing sampling malfunctions caused by sampler 1 equipment failure.
