Description

Technical Field

[0001] This utility model relates to the technical field of coal monitoring equipment, and in particular to a coal moisture monitoring device. Background Technology

[0002] Coal is a fossil fuel and a relatively traditional energy source. According to modern science and technology, coal is a mineral resource formed from the remains of ancient plants through complex physical and chemical changes such as geological alterations. Coal needs to be mined and then transported to a suitable site for storage.

[0003] Since coal is not used directly after mining but needs to be stored, relevant moisture monitoring devices are required for coal storage. Because the coal in storage is piled on the ground and is quite thick, existing moisture monitoring devices can only monitor the shallow layer of stored coal and avoid monitoring the moisture content. This makes it inconvenient to monitor the deeper parts of the coal, which can lead to inaccurate coal moisture data and may cause coal storage safety accidents.

[0004] Therefore, how to provide a coal moisture monitoring device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a coal moisture monitoring device. This invention solves the problem that existing coal moisture monitoring devices in coal storage can only monitor the moisture of the shallow and surface layers of coal, but cannot monitor the moisture of deeper layers, resulting in inaccurate coal moisture monitoring data.

[0006] A coal moisture monitoring device according to an embodiment of the present utility model includes a base and a moisture monitoring head. A storage component is provided on the top of the base, a monitoring control box is provided on the top of the storage component, and a height adjustment component is provided on the top of the base. The height adjustment component includes an insertion component, and the moisture monitoring head is disposed on the end face of the insertion component.

[0007] The height adjustment assembly also includes a guide tube, a fixing ring, an adjustment knob, an annular external toothed groove, a lifting screw, and a drive assembly that drives the annular external toothed groove and the adjustment knob to rotate. The guide tube is vertically fixed at the top of the base near the center. The fixing ring is fixed at the top of the guide tube. The adjustment knob is rotatably connected to the inner wall of the fixing ring through a bearing. The lifting screw is movably connected to the surface of the guide tube. One end of the lifting screw passes through the adjustment knob and extends to directly above the adjustment knob. The adjustment knob is threaded onto the surface of the lifting screw. The drive assembly meshes with the annular external toothed groove, and the insertion assembly is located at the top of the lifting screw.

[0008] The drive assembly includes a drive motor and a drive gear. The drive motor is fixed to the side of the fixed ring, and the drive gear is fixedly sleeved on the end face of the output shaft of the drive motor. The drive gear meshes with the annular external tooth groove.

[0009] The insertion assembly includes a crossbar and an insertion rod. One end of the crossbar is fixed to the top surface of the lifting screw and is perpendicular to the lifting screw. The other end of the crossbar is fixed to one end of the insertion rod and the crossbar and the insertion rod are perpendicular to each other. The other end of the insertion rod is set vertically downward, and the moisture monitoring head is set at the bottom end of the insertion rod.

[0010] The bottom end of the insertion rod is provided with a tapered head.

[0011] The storage assembly includes a storage tank, a water pump, a connecting water pipe, an inner cavity, and a nozzle. The storage tank is fixed to the top of the base, and the water pump is fixed to the top of the storage tank. The output port of the water pump is fixedly connected to the end face of the connecting water pipe. The other end of the connecting water pipe is fixed to the surface of the guide pipe and communicates with the guide pipe. A sealing piston is provided on the bottom end face of the lifting screw. The sealing piston is tightly fitted to the inner wall of the guide pipe. The inner cavity is opened inside the lifting screw, the crossbar, and the insertion rod. The nozzle is embedded in the surface of the insertion rod at the position closest to the bottom end.

[0012] The height adjustment assembly also includes a guide rod and a guide block. The guide block is fixed to the side of the guide tube, the guide rod is fixed to the top of the lifting screw, and the guide block is movably sleeved on the surface of the guide rod. The guide rod is parallel to the insertion rod and the lifting screw.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a height adjustment component and a moisture monitoring head, the base is placed on the stored coal, and then the height adjustment component is activated to control the moisture monitoring head to be inserted into the coal. In this way, the height adjustment component can drive the moisture monitoring head to any depth in the coal to monitor the coal. This solves the problem that existing coal moisture monitoring devices can only monitor the moisture of the shallow and surface layers of coal and cannot monitor the moisture of deeper layers, resulting in inaccurate coal moisture monitoring data.

[0015] By setting up a storage component, when the moisture monitoring head detects low moisture content, the storage component is controlled by the monitoring control box to deliver water to the coal, thereby compensating for the water shortage and preventing safety hazards caused by low moisture content and dryness of the coal.

[0024] The height adjustment assembly 5 also includes a guide tube 7, a fixing ring 8, an adjustment knob 9, an annular external toothed groove 10, a lifting screw 11, and a drive assembly 12 that drives the annular external toothed groove 10 and the adjustment knob 9 to rotate. The guide tube 7 is vertically fixed at the top of the base 1 near the center. The fixing ring 8 is fixed at the top of the guide tube 7. The adjustment knob 9 is rotatably connected to the inner wall of the fixing ring 8 through a bearing. The lifting screw 11 is movably connected to the surface of the guide tube 7. One end of the lifting screw 11 passes through the adjustment knob 9 and extends to directly above the adjustment knob 9. The adjustment knob 9 is threaded onto the surface of the lifting screw 11. The drive assembly 12 meshes with the annular external toothed groove 10. The insertion assembly 6 is set at the top of the lifting screw 11. The drive assembly 12 includes a drive motor 13 and a drive gear 14. The drive motor 13 is fixed to the side of the fixing ring 8. The drive gear 14 is fixedly sleeved on the end face of the output shaft of the drive motor 13. The drive gear 14 meshes with the annular external toothed groove 10. The drive assembly 12 mainly drives the adjustment knob 9 to rotate.

[0025] The height adjustment assembly 5 also includes a guide rod 23 and a guide block 24.
