DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0019] like Figure 1-Figure 3 As shown, a transmission pipeline blockage monitoring device comprises a transmission pipeline 1, a monitoring pipeline 2, a mounting bracket 3, a mandrel 4 and a detection switch 5. The transmission pipeline 1 is provided with a monitoring pipeline 2, and the monitoring pipeline 2 is used to install components required for monitoring;

[0020] A mounting bracket 3 is provided at the upper end of the monitoring pipeline 2, a detection switch 5 is provided in the middle of the mounting bracket 3, a fixing plate 6 is provided below the mounting bracket 3, a push rod 4 which can cooperate with the detection switch 5 is provided in the middle of the fixing plate 6, and the detection switch 5 is a proximity switch. After the push rod 4 moves upward and touches the detection switch 5, the detection switch 5 is triggered, indicating that the material in the conveying pipeline 1 is blocked, causing the material to accumulate in the pipeline 2, and the push rod 4 is lifted up, and maintenance is required.

[0021] A rubber plate 7 that can cooperate with the push rod 4 is provided on the monitoring pipeline 2. When the material in the conveying pipeline 1 is conveyed normally, the rubber plate 7 will not be impacted. At this time, the push rod 4 is fixed in position and will not touch the detection switch 5. When the material in the conveying pipeline 1 is blocked, the material level in the detection pipeline 2 gradually rises until it presses against the rubber plate 7. The rubber plate 7 expands and lifts the push rod 4 upward, and the detection switch 5 is triggered.

[0022] Furthermore, a sealing cover 8 is provided on the mounting bracket 3, a connecting hole 9 is opened on one side of the sealing cover 8, a plug 10 of the detection switch 5 is fixed in the connecting hole 9, and the sealing cover 8 can protect the internal components from being eroded by rain.

[0023] Furthermore, a connecting flange 11 is provided at the upper end of the monitoring pipeline 2, and the mounting bracket 3 is connected to the connecting flange 11 by a connecting piece 12, and the connecting piece 12 is a bolt for easy assembly.

[0024] Furthermore, a gasket 13 is provided between the connecting flange 11 and the mounting bracket 3, and the gasket 13 separates the connecting flange 11 and the mounting bracket 3 by a certain distance, so that there is a certain distance between the rubber plate 7 and the push rod 4. By adjusting the thickness of the gasket 13, the stroke of the push rod 4 can be adjusted, so that the rubber plate 7 can better cooperate with the push rod 4.

[0025] Furthermore, a mounting hole 14 is provided in the middle of the fixing plate 6 , a fixing ring 15 is provided on the fixing plate 6 outside the mounting hole 14 , and the rod portion of the push rod 4 passes through the fixing ring 15 and the mounting hole 14 and then cooperates with the rubber plate 7 .

[0026] Furthermore, an annular boss 16 is provided at the upper end of the push rod 4 , and the annular boss 16 prevents the push rod 4 from falling off the fixing plate 6 .

[0027] Working principle: When the utility model is in use, first place the rubber sheet 7 on the connecting flange 11, then press the gasket 13 on the rubber sheet 7, then place the push rod 4 inside the fixing ring 15 on the fixing plate 6, then place the mounting bracket 3 on the gasket 13, and use the connecting piece 12 to connect the mounting bracket 3 with the connecting flange 11. At this time, the rubber sheet 7 and the gasket 13 are also fixed by the connecting piece 12, and then install the detection switch 5 on the mounting bracket 3, and cover the sealing cover 8, and fix the plug of the detection switch 5 in the connecting hole 9; when the material in the conveying pipeline 1 is normally conveyed, the rubber sheet 7 will not be impacted, and the push rod 4 is fixed at this time and will not touch the detection switch 5. When the material in the conveying pipeline 1 is blocked, the material in the detection pipeline 2 gradually accumulates and rises until it supports the rubber sheet 7. The rubber sheet 7 expands upward to lift the push rod 4, and the detection switch 5 is triggered. The system receives a signal, and the staff can know in time that the conveying pipeline 1 is blocked and respond.
