DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] like Figures 1 to 4 As shown, the portable mine seam monitoring device includes a monitoring box body 100, in which a first magnetic induction component 130 and a second magnetic induction component 140 are arranged, one end of the first magnetic induction component 130 is fixed on the side wall of the monitoring box body 100, and one end of the second magnetic induction component 140 is fixed on the bottom plate of the monitoring box body 100, and a rotatable and retractable monitoring cable 120 is also arranged therebetween, and one end of the monitoring cable 120 passes through the side wall of the monitoring box body 100 and extends to the outside of the monitoring box body 100, wherein the monitoring cable 120 is embedded with equidistantly arranged magnetic strips 121, and the first magnetic induction component 130 and the second magnetic induction component 140 are both in contact with the monitoring cable 120. In this way, by embedding the magnetic strips 121 equidistantly in the monitoring cable 120, the monitoring cable 120 can intermittently undergo magnetic induction with the first magnetic component 130 and / or the second magnetic component 140 during the extension and retraction process, so that the magnetic field changes intermittently and is recorded by the first magnetic component 130 and / or the second magnetic component 140, thereby obtaining the moving distance of the monitoring cable 120.

[0028] Optionally, the monitoring cable 120 extends to the outer part of the monitoring box body 100, and a connecting buckle 122 is fixed at its end. In this way, the device is connected to the anchor points on both sides of the seam body through the connecting buckle 122, so that the device is located between the anchor points on both sides of the seam body. When the seam body changes, the anchor point connected to the connecting buckle 122 will drive the monitoring cable 120 to move synchronously, so as to obtain the change data of the seam body through the moving length of the monitoring cable 120.

[0029] Optionally, the first magnetic sensing element 130, the second magnetic sensing element 140 and the monitoring cable 120 form a monitoring unit, and two or more monitoring units are provided in the monitoring box 100. In this way, the data changes of multiple gaps can be monitored by multiple monitoring units.

[0030] Optionally, the second magnetic sensing member 140 is arranged near the exit position of the monitoring cable 120, and is located at the lower end of the first magnetic sensing member 130. In this way, when the monitoring cable 120 moves, the first magnetic sensing member 130 and the second magnetic sensing member 140 are synchronously sensed with the monitoring cable 120, wherein the second magnetic sensing member 140 is used for verification, and the sensing data obtained by the first magnetic sensing member 130 is checked to ensure that the sensing data obtained by the first magnetic sensing member 130 and the second magnetic sensing member 140 are the same. With the cooperation of the first magnetic sensing member 130 and the second magnetic sensing member 140, the deviation of the data is effectively reduced.

[0031] like Figure 3 As shown, the spacing between the magnetic strips 121 is 1 mm. Thus, taking the case where five magnetic strips 121 pass through the first magnetic sensing element 130 and / or the second magnetic sensing element 140 as an example, the moving distance of the monitoring cable 120 is 10 mm.

[0032] like Figure 4 As shown, the monitoring box body 100 further includes a main body 110, a longitudinally arranged slot is provided on the side wall thereof, and a matching guide assembly 150 is provided in the slot. In this way, one end of the monitoring cable 120 passes through the guide assembly 150 and extends to the outside of the main body 110. The extension or retraction of the monitoring cable 120 is relatively smooth relative to the guide assembly 150, which avoids the degree of wear of the monitoring cable 120 when it is repeatedly extended or retracted, and prolongs the service life of the monitoring cable 120.

[0033] Optionally, the guide assembly 150 includes a roller 151 and a water-blocking structure 152 . There are two rollers 151 disposed in the slot in an opposite manner. The water-blocking structure 152 is disposed on a side of the slot facing the monitoring cable 120 .

[0034] Optionally, two water-blocking structures 152 are provided, which are arranged on both sides of the slot in an opposite installation manner, and the side of the water-blocking structure 152 facing the slot is provided with an inclined surface 153. In this way, when the monitoring cable 120 retracts, water or dust and other debris attached to the detection cable will be blocked by the water-blocking structure 152, effectively preventing water or debris from entering the device.

[0035] Optionally, a storage battery 160 is further provided in the monitoring box body 100. In this way, the storage battery 160 can provide power for the device, so that the device can perform monitoring work without an external power supply.

[0036] Optionally, a power connection socket 161 is provided on the side wall of the monitoring box body 100. In this way, the storage battery 160 can be charged by an external power supply when the storage battery 160 is exhausted, thereby ensuring the working power demand of the device.

[0037] Optionally, the power connection socket 161 can be connected to a photovoltaic panel or a wind power device. In this way, when there is no external power supply in the wild, the photovoltaic panel or the wind power device can provide additional power supply for the device to improve the endurance of the device monitoring work.

[0038] Optionally, a plurality of connection sockets are provided in the monitoring box body 100. In this way, it is convenient to connect the components through corresponding cables.

[0039] like Figure 5 As shown, the first magnetic induction component 130 includes a housing 131 and a magnetic induction terminal 133. A through slot is provided in the housing 131, wherein the opening at one end is larger than the opening at the other end. The magnetic induction terminal 133 is embedded from the end with the larger opening, and its embedded end passes through the end with the smaller opening and protrudes out of the housing 131. In this way, the magnetic induction terminal 133 can slide in the through slot, and the end with the smaller opening has a limiting effect on the magnetic induction terminal 133, thereby preventing the magnetic induction terminal 133 from being overly extended and causing the magnetic induction terminal 133 to escape from the housing 131, so that the first magnetic induction component 130 can work stably.

[0040] Optionally, the end of the magnetic induction terminal 133 opposite to the embedded end is provided with a limiting protrusion on its opposite side wall, and the width of the limiting protrusions on both sides is greater than the width of the end with the smaller opening of the through slot. In this way, the width of the limiting protrusion is greater than the end with the smaller opening of the through slot, so that the position where the limiting protrusion of the magnetic induction terminal 133 is provided cannot pass through the end with the smaller opening of the through slot, thereby limiting the magnetic induction terminal 133 and preventing the magnetic induction terminal 133 from escaping from the housing 131.

[0041] Optionally, a cable connection seat 132 is provided on the outer wall of the housing 131 for connecting a data cable. In this way, the first magnetic induction element 130 can be connected to other components through the cable connection seat 132 to perform data transmission.

[0042] like Figure 5 and Figure 6 As shown, a longitudinally arranged magnetic sensing block 134 is provided at the embedded end of the magnetic sensing terminal 133. In this way, the magnetic sensing terminal 133 can reduce the contact area with the magnetic sensing strip 121 while ensuring mutual induction with the magnetic sensing strip 121 by relying on the longitudinally arranged magnetic sensing block 134, effectively reducing the situation of continuous data reading caused by excessive contact area between the magnetic sensing block 134 and the magnetic sensing strip 121, and effectively improving the accuracy of data reading.

[0043] Optionally, the length of the magnetic sensing block 134 is less than the length of the magnetic sensing strip 121. In this way, the magnetic sensing block 134 can be completely within the sensing range of the magnetic sensing strip 121. Compared with the case where the length of the magnetic sensing block 134 is greater than or equal to the length of the magnetic sensing strip 121, the situation where part of the magnetic sensing block 134 is outside the sensing range of the magnetic sensing strip 121 is avoided, thereby improving the sensing accuracy of the magnetic sensing block 134 and the magnetic sensing strip 121.

[0044] like Figure 6 As shown, the end of the magnetic sensing terminal 133 away from the magnetic sensing block 134 is provided with a spring 135 abutting against it. In this way, the magnetic sensing terminal 133 can automatically adjust the length of the magnetic sensing terminal 133 extending out of the housing 131 according to the thickness of the monitoring cable through the elasticity of the spring 135, ensuring that the magnetic sensing terminal 133 can always abut against the side wall of the monitoring cable, so as to improve the sensing accuracy of the magnetic sensing terminal 133 and the magnetic sensing strip 121.

[0045] It can be understood that when the monitoring cable continues to extend from the monitoring box body 100, the diameter of its coil will gradually decrease with the length of the extension, and at the same time the spring 135 will be released, pushing the magnetic sensing terminal 133 to move toward the monitoring cable, so that the magnetic sensing terminal 133 is always in contact with the side wall of the detection cable; on the contrary, when the monitoring cable is retracted, the diameter of its coil will gradually increase with the length of the retraction, and at the same time the magnetic sensing terminal 133 will be squeezed, and the magnetic sensing terminal 133 indirectly squeezes the spring 135, so that the spring 135 is gradually compressed and its elasticity is increased, pushing the magnetic sensing terminal 133 to move toward the monitoring cable, so that the magnetic sensing terminal 133 is always in contact with the side wall of the detection cable toward one end of the monitoring cable.

[0046] Preferably, the outer wall of the second magnetic sensing member 140 is provided with a magnetic sensing block 134 identical to that of the first magnetic sensing member 130. In this way, the magnetic sensing block 134 identical to that of the first magnetic sensing member 130 is configured to ensure that the data collected by the first magnetic sensing member 130 is identical, thereby reducing the error in the review of the data collected by the first magnetic sensing member 130 and improving the accuracy of the review.

[0047] Optionally, the second magnetic sensing element 140 is a columnar structure. In this way, the columnar structure can reduce the wear of the monitoring cable 120 during repeated expansion and contraction, thereby increasing the service life of the monitoring cable 120.

[0048] like Figure 7 and Figure 8 As shown, a swivel seat 123 is further provided in the monitoring box body 100 for connecting the coiled connection of the monitoring cable 120. In this way, the monitoring cable 120 is arranged on the swivel seat 123 in a coiled form, so that the monitoring cable 120 rotates around the central rotating shaft of the swivel seat 123 when it is extended and retracted, thereby improving the extension and retraction efficiency of the monitoring cable 120.

[0049] like Figure 8 As shown, a plane vortex spring 124 is arranged in the swivel seat 123. In this way, when the monitoring cable 120 extends outward, the swivel seat 123 is driven to rotate, and the plane vortex spring 124 arranged in the swivel seat 123 is compressed during the rotation process, so that the plane vortex spring 124 has a pulling effect on the monitoring cable 120. When the fixed point outside the monitoring cable 120 is released, the monitoring cable 120 can be automatically recovered by the plane vortex spring 124.

[0050] Optionally, the swivel seat 123 further includes a support 125, a bearing 126 and a column 127. A through hole is drilled at the center of the support 125 for installing the bearing 126. One end of the column 127 is embedded in the bearing 126 and protrudes through the bearing 126 to the other end of the bearing 126 and is connected to the plane vortex spring 124. In this way, when the monitoring cable 120 is extended and retracted, the plane vortex spring 124 can be driven to rotate and compress synchronously through the column 127 connected thereto.

[0051] Optionally, a slot is provided on the side wall of the column 127 for connecting the monitoring cable 120. In this way, one end of the monitoring cable 120 is installed in the slot through a fixed structure, and when the monitoring cable 120 is extended and retracted, the column 127 will be driven to rotate synchronously.

[0052] like Figure 1 and Figure 2As shown, the apparatus further includes an electrical box 200, which is disposed on the top of the monitoring box body 100. In this way, the electrical box 200 is connected to the first magnetic sensing element 130 and / or the second magnetic sensing element 140 in the monitoring box body 100 through a cable, and the data between the first magnetic sensing element 130 and / or the second magnetic sensing element 140 and the monitoring cable 120 are collected and processed, and sent to the staff, so that the staff can understand the monitoring situation in time, thereby improving the working efficiency of the seam monitoring.

[0053] Optionally, a first circuit board 210 and a second circuit board 220 are provided in the electrical box 200, which are used for data acquisition and processing and data transmission respectively.

[0054] Optionally, an antenna connection seat 221 is provided on the side wall of the electrical appliance box 200 , and an antenna 222 is installed in the antenna connection seat 221 .

[0055] Optionally, a first sealing ring 230 is provided at one end of the electrical box 200 facing the monitoring box body 100 .

[0056] Optionally, a second sealing ring 231 is provided at one end of the electrical box 200 away from the monitoring box body 100 .

[0057] like Figure 1 and Figure 2 As shown, a panel 300 is embedded on the top of the electrical box 200, and a display screen 310, operation buttons 320 and a warning light 330 are provided on the panel 300. In this way, the parameters and thresholds of the equipment are set by cooperating with the operation buttons 320 and the display screen 310 provided on the panel 300. When the movement of the seam approaches the threshold and exceeds the threshold, a warning is given through the warning lights 330 of different colors, and the warning information is sent to the staff at the same time.

[0058] It can be understood that before installing the equipment, it is necessary to drive anchor rods and other fixings on both sides of the seam, and connect the monitoring cables 120 at both ends of the monitoring box 100 to the anchor rods and other fixings through the connecting buckles 122, so that the device is located between the seams, and the device is set through the provided operation buttons 320 and the display screen 310 so that the extended length of the monitoring cable 120 on the device is reset to zero. At this time, the hands of the monitoring cables 120 on both sides of the device are all in the zero state. When the seam changes, the monitoring cables 120 will be pulled to move at the same time, so that the extended length of the monitoring cables 120 changes. The first magnetic sensing element 130 senses the magnetic sensing strip 121 in the monitoring cable 120 and records the extended length of the monitoring cable 120. At the same time, the second magnetic sensing element 140 senses the magnetic sensing strip 121 in the monitoring cable 120 and records the extended length of the monitoring cable 120, and verifies it with the extended length of the monitoring cable 120 obtained by the first magnetic sensing element 130, so as to confirm the accuracy of the data obtained by the first magnetic sensing element 130. After obtaining accurate data, the device transmits the obtained data to the terminal held by the staff, so that the staff can implement corresponding countermeasures.

[0059] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
