Description

Technical Field

[0001] This utility model relates to the field of coal moisture detection technology, specifically a coal moisture detection device. Background Technology

[0002] Coal moisture detection is crucial in the operation of ports transporting coal from the north to the south. Excessive coal moisture will result in very high coal viscosity, which will stick to the inside of the transfer tower during transportation, causing blockage of the transfer tower hopper and making it difficult to transport coal.

[0003] Currently, there are deviations in the detection of coal moisture content during actual transportation. In addition, due to weathering, the moisture content of coal on the outside of the coal stack is measured on the surface, resulting in a lower moisture level. Meanwhile, the moisture content inside the coal cannot be detected, leading to an inability to reflect the actual moisture content of the coal.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a coal moisture detection device to solve the problem that there are deviations in the detection of coal moisture during actual transportation. At the same time, due to the weathering of coal on the outside of the coal pile, the moisture content of the coal surface is low, while the moisture content inside the coal cannot be detected, resulting in the inability to reflect the actual moisture content of the coal.

[0006] The technical solution adopted by this application to solve its technical problem is: a coal moisture detection device, including a fixed rod, a probe rod is threadedly connected to one end of the fixed rod, a probe cover for protecting the probe is threadedly connected to one end of the probe rod, a temperature and humidity detector for detecting the temperature of the coal pile is fixedly installed at the other end of the fixed rod, and a gripping component for holding the fixed rod is fixedly installed on one side of the outer wall of the fixed rod.

[0007] Furthermore, a threaded groove is provided in the middle of one end of the fixing rod, and a hollow stud is threadedly connected in the inner cavity of the threaded groove. A hollow extension rod is fixedly installed at one end of the hollow stud, and the inner wall of one end of the hollow extension rod is provided with internal threads.

[0008] Furthermore, a hollow stud is fixedly installed at the other end of the probe rod, a mating thread is provided at one end of the outer wall of the probe rod, and a detection probe is installed in the inner cavity of one end of the probe rod by means of a probe fixing screw.

[0009] Furthermore, a threaded through groove is provided in the middle of the other end of the probe cover, a funnel groove is provided at one end of the threaded through groove, and a feed groove is provided in the middle of one end of the probe cover.

[0010] Furthermore, the feed trough is shaped like a rectangular opening, which is designed to prevent larger coal pieces from damaging the probe.

[0011] Furthermore, the grip assembly includes an arc-shaped handle post and an anti-slip rubber layer embedded in one end of the arc-shaped handle post. A hollow ring is fixedly installed at the other end of the arc-shaped handle post, and a contact rod is fixedly installed at one end of the outer wall of the hollow ring.

[0012] Furthermore, elastic elements are fixedly installed at the upper and lower ends of the inner wall of the hollow ring, and a semi-circular clamp is fixedly installed at one end of the elastic element.

[0013] The beneficial effects of this application are as follows: The coal moisture detection device provided by this application connects the threaded through groove in the inner cavity of the probe cover with the mating thread, allowing the detection probe to be inserted into the inner cavity of the funnel trough. The holding assembly drives the fixing rod and the detection rod into the interior of the coal pile. Since the shape of the feed trough is set as a rectangular opening, it can be used to control the size of the coal entering, thereby preventing large coal pieces from damaging the detection probe. At the same time, the detection probe can detect the coal inside the coal pile, and the detected humidity is transmitted to the temperature and humidity detector through the probe connection line, thereby improving the accuracy of coal pile humidity detection.

[0018] like Figure 1 As shown, a coal moisture detection device includes a fixed rod 1. One end of the fixed rod 1 is threadedly connected to a probe rod 2, and one end of the probe rod 2 is threadedly connected to a probe cover 3 for protecting the probe. The other end of the fixed rod 1 is fixedly installed with a temperature and humidity detector 4 for detecting the temperature of the coal pile. A gripping assembly 5 for holding the fixed rod 1 is fixedly installed on one side of the outer wall of the fixed rod 1. The inner cavities of the fixed rod 1, the probe rod 2, and the probe cover 3 are all through-connected to allow the wiring harness of the temperature and humidity detector 4 to pass through.

[0019] The temperature and humidity detector 4 is a DM-1091 temperature and humidity detector manufactured by Delixi Electric. It is installed at the end of the fixed rod 1 and is electrically connected to the detection probe 24 through the probe connection line of the temperature and humidity detector 4.

[0020] The temperature and humidity detector 4 and the detection probe 24 are connected via a calculator and probe connection line. The detector is used to receive, display and process the coal humidity data detected by the probe. This is existing technology. The circuits, electronic components and modules of the temperature and humidity detector 4 and the detection probe 24 involved in this utility model are all existing technologies. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve any improvement to the software and methods.

[0021] like Figure 2As shown, a threaded groove 11 is provided in the middle of one end of the fixed rod 1. A hollow stud 12 is threadedly connected in the inner cavity of the threaded groove 11. The inner cavity of the hollow stud 12 is hollow and through. A hollow extension rod 13 is fixedly installed at one end of the hollow stud 12. The inner wall of one end of the hollow extension rod 13 is provided with internal threads 14. The inner cavity of the hollow extension rod 13 is through and connected.

[0022] like Figures 2-3 As shown, a hollow stud 21 is fixedly installed at the other end of the probe rod 2. A mating thread 22 is provided at one end of the outer wall of the probe rod 2. A detection probe 24 is installed in the inner cavity of one end of the probe rod 2 by means of a probe fixing screw 23. The detection probe 24 is electrically connected to the temperature and humidity detector 4 through a connecting wire. The connecting wire harness is set in the inner cavity of the fixed rod 1 and the probe rod 2.

[0023] The detection probe 24 is fixed to the detection rod 2 by the probe fixing set screw 23 to ensure the stability of the detection probe 24 during the detection process.

[0024] The hollow stud 12 and the threaded groove 11 are threaded together, and the hollow stud 21 and the internal thread 14 are threaded together, so that the fixed rod 1 and the probe rod 2 can be extended. The purpose is to extend the detection probe 24 into the coal pile to detect the humidity of the coal, so as to avoid inaccurate humidity detection due to weathering of the coal outside the coal pile.

[0025] like Figures 2-3 As shown, a threaded through groove 31 is provided in the middle of the other end of the probe cover 3. The threaded through groove 31 and the mating thread 22 are threadedly connected. A funnel groove 32 is provided at one end of the threaded through groove 31. A feed groove 33 is provided in the middle of one end of the probe cover 3. The detection probe 24 is movably installed in the inner cavity of the threaded through groove 31 and the funnel groove 32.

[0026] like Figures 2-3 As shown, the feed trough 33 is designed with a rectangular opening to prevent larger coal pieces from damaging the probe.

[0027] The probe cover 3 is connected to the mating thread 22 by threaded through groove 31. The feed trough 33 is shaped as a rectangular opening to control the size of the coal entering, while preventing large coal blocks from damaging the detection probe 24. When the probe cover 3 is screwed into the detection rod 2, the detection probe 24 can be inserted into the funnel groove 32 for detection.

[0028] In this application, during testing, the probe 24 is inserted into the inner cavity of the funnel trough 32 by threading the threaded through groove 31 in the inner cavity of the probe cover 3 with the mating thread 22. The holding assembly 5 drives the fixing rod 1 and the probe 2 into the interior of the coal pile. Since the feed trough 33 is designed as a rectangular opening, it can be used to control the size of the coal entering, thereby preventing large coal pieces from damaging the probe 24. At the same time, the probe 24 can detect the coal inside the coal pile, and the detected humidity is transmitted to the temperature and humidity detector 4 through the probe connection line, thereby improving the accuracy of the humidity detection of the coal pile.
