[0050] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the scope of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0051] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0052] Embodiment 1:

[0053] As shown in the accompanying Figures 1-2 ​The utility model discloses a kind of safety evaluation auxiliary devices based on goaf tower, including controller, fixed ring 100 and outer top ring 101, the outer side wall of fixed ring 100 upper portion is symmetrically bolted and connected with connecting rod 102, fixed ring 100 is bolted and connected with outer top ring 101 by connecting rod 102;Outer top ring 101 outer side is symmetrically equipped with the inclination angle instrument 103 for collecting tower inclination, controller is used to receive the signal of inclination angle instrument 103, and inclination angle instrument 103 is located at the two sides of connecting rod 102 respectively.

[0054] Outer top ring 101 bottom is equipped with the rotating assembly for driving inclination angle instrument 103 to rotate and revolve around fixed ring 100;Rotating assembly includes several rotating rings 104, and inclination angle instrument 103 is bolted and connected to the outer side wall of rotating ring 104;Rotating ring 104 is rotated and slidably fitted with outer top ring 101, and several cylindrical pins 105 are bolted and connected with the top of outer top ring 101 along its circumferential direction;The inner side wall of rotating ring 104 is opened with several inclinedly arranged helical grooves, and the helical groove is engaged with cylindrical pin 105;Rotating groove is opened in the outer side wall of rotating ring 104, and vertical rod 106 is rotatably fitted in rotating groove;Vertical rod 106 bottom is equipped with the driving assembly 200 for driving it to revolve around fixed ring 100.

[0055] Driving assembly 200 includes gear 201, outer gear ring 202 and driving member for driving gear 201 to rotate, and driving member is driving motor 203 in the embodiment;Controller is used to control driving motor 203 to operate according to inclination angle instrument 103 signal, and the number of teeth of gear 201 rotation is recorded according to inclination information;Driving motor 203 is bolted and connected to the outer side wall of fixed ring 100 lower portion, and the output shaft of driving motor 203 is coaxially bolted and connected with gear 201, and gear 201 is engaged with outer gear ring 202 each other;The bottom end of vertical rod 106 is bolted and connected to the top of outer gear ring 202.

[0056] As Figure 1As shown, by driving the motor 203 to rotate the gear 201, the gear 201 drives the outer gear ring 202 engaged therewith to rotate; since the vertical rod 106 is bolted and fixedly connected with the outer gear ring 202, the driving motor 203 is bolted and fixedly connected to the outer side wall of the fixed ring 100; therefore, the outer gear ring 202 can drive the vertical rod 106 to rotate around the fixed ring 100, and the vertical rod 106 drives the rotation ring 104 rotatingly matched therewith to revolve and rotate. When the rotation ring 104 rotates, the inclination information of the tower is collected by the inclinometer 103, in this process, the controller records the number of teeth of the gear 201 rotating according to the initial inclination information collected by the inclinometer 103, and judges the direction and position of the inclinometer 103 rotating in turn based on the number of teeth; in the subsequent process of monitoring the inclination of the tower, the inclination offset in different positions and different axial directions of the tower is judged according to the change of the number of teeth and the initial inclination information; thereby realizing the evaluation of the safety of the tower. For example, when the inclination in the vertical axial direction of the tower is collected for the first time, the number of teeth of the gear 201 rotating is 30 teeth, and when the inclination data in the vertical axial direction is collected in the subsequent monitoring process, the number of teeth of the gear 201 rotating is adjusted to 30 teeth, so as to judge the inclination offset in different axial directions.

[0057] The specific implementation process is as follows: first, before the tower monitoring, the fixed ring 100 is fixedly connected to the outer side wall of the tower by bolts, and the vertical rod 106 revolves around the fixed ring 100 by the driving motor 203 provided; since the rotation ring 104 is in rotating and sliding cooperation with the outer top ring 101, the outer side wall of the rotation ring 104 is provided with a rotating groove, and the vertical rod 106 is in rotating cooperation with the rotating groove; therefore, when the vertical rod 106 revolves around the fixed ring 100, the rotation ring 104 can move synchronously with the vertical rod 106. Since the outer top ring 101 is bolted and fixedly connected with a plurality of cylindrical pins 105, the side wall of the rotation ring 104 is provided with a spiral groove arranged obliquely, and the cylindrical pins 105 are engaged with the spiral groove; therefore, when the vertical rod 106 drives the rotation ring 104 to revolve around the fixed ring 100, the cylindrical pins 105 will pass through the obliquely arranged spiral groove one by one, so that the rotation ring 104 rotates, and the rotation and revolution of the rotation ring 104 are realized in this way. For example, when the vertical rod 106 drives the rotation ring 104 to move to the left, the rotation ring 104 will rotate clockwise at this time through the special structure of the spiral groove and the cylindrical pin 105; conversely, when the vertical rod 106 drives the rotation ring 104 to move to the right, the rotation ring 104 will rotate counterclockwise. Figure 2

[0058] ​Since the inclinometer 103 is bolted to the outer side wall of the rotating ring 104 respectively, the position of the inclinometer 103 can be adjusted by rotating the rotating ring 104, and the inclination information of the tower at different positions and different axial directions is collected during the rotation, so that the inclination of the tower can be monitored in multiple directions, the monitoring accuracy of the device is further improved by combining the multi-directional information, the integrity of the monitoring results is ensured, and the device has stronger adaptability to the complex geological conditions of the goaf. And it can reduce the number of sensors used, thereby reducing the cost of the device; through such an automatic collection method, the monitoring time is shortened, and the work efficiency is improved; the inclination change of the tower can be monitored in real time and continuously, which provides strong support for timely safety measures.

[0059] Embodiment 2:

[0060] As shown in the accompanying drawings, Figure 1 The difference from the above embodiments is that a plurality of limiting rods 204 are bolted to the inner side wall of the outer gear ring 202, and the outer side wall of the fixed ring 100 is provided with an annular groove, and the end of the limiting rod 204 away from the outer gear ring 202 is in rotating cooperation with the annular groove.

[0061] The specific implementation process is as follows: through the design of the limiting rod 204 and the annular groove, the outer gear ring 202 can be limited to always revolve around the outer side of the fixed ring 100 without deviation, thereby ensuring the stability of the entire structure and further improving the accuracy of data monitoring.

[0062] Embodiment 3:

[0063] As shown in the accompanying drawings, Figure 1 The difference from the above embodiments is that the distance between the outer top ring 101 and the fixed ring 100 is greater than the rotating diameter of the rotating ring 104.

[0064] The specific implementation process is as follows: by setting the distance between the outer top ring 101 and the fixed ring 100 to be greater than the rotating diameter of the rotating ring 104, a space is provided for the inclinometer 103 outside the rotating ring 104 to facilitate data collection.

[0065] Embodiment 4:

[0066] As shown in the accompanying drawings, Figure 1 The difference from the above embodiments is that the inner side wall of the fixed ring 100 is bolted with a vibration sensor 205, and the controller is used to receive and store the vibration signals emitted by the vibration sensor 205.

[0067] The specific implementation process is as follows: in addition to monitoring the inclination of the tower, the vibration of the tower itself can also be detected by the vibration sensor 205, providing more comprehensive structure health state information. The controller receives data from the vibration sensor 205 and the inclinometer 103, and can further perform correlation analysis, and more accurately assess the safety condition of the tower by comprehensively considering vibration and inclination information.

[0068] Embodiment 5:

[0069] As shown in the accompanying drawings, Figure 1 The difference from the above embodiments is that the outer gear ring 202 is fixedly connected with an elevation positioner 206 at the top, and the controller is used to receive the elevation signal sent by the elevation positioner 206, and record the number of teeth of the gear 201 according to the elevation signal.

[0070] The specific implementation process is as follows: the spatial position of the tower is obtained by the elevation positioner 206, and accurate position information can be provided when data anomalies are encountered during monitoring. Moreover, by rotating the outer gear ring 202 around the fixed ring 100, elevation information at different positions can be collected, for example, when collecting elevation information at the true north position of the tower for the first time, the number of teeth of the gear 201 is 77 teeth, and when collecting elevation information at the true north position during subsequent monitoring, the number of teeth of the gear 201 is adjusted to 77 teeth, so as to distinguish the elevation information at different positions. By continuously collecting and analyzing these data, the settlement deformation data of the tower at different positions can be accurately captured, so as to evaluate its safety state; by combining with the inclinometer 103 and the vibration sensor 205, the running safety of the tower can be comprehensively monitored.

[0071] Embodiment 6:

[0072] As shown in the accompanying drawings, Figure 3 The difference from the above embodiments is that the present application also provides a safety evaluation method based on the tower in the goaf, comprising the following steps:

[0074] Among them, different positions include but are not limited to true south, true north, true east, true west, southwest, southeast, northeast and northwest; different axial directions include horizontal, vertical, inverted horizontal and inverted vertical; by the comprehensive use of the inclinometer 103, the vibration sensor 205 and the elevation positioner 206, the inclination data, the vibration data and the elevation data of the tower at different positions and different axial directions can be comprehensively collected, providing a rich data basis for safety evaluation.

[0075] S2, data transmission: using wireless transmission technology to collect the tilt data, vibration data and elevation data for wireless transmission. Among them, the wireless transmission technology is selected from one or more of Bluetooth, 4G, 5G, WiFi, NB-loT, Zigbee and LoRa; in this embodiment, the wireless transmission technology adopts LoRa base station to establish, and the collected data is transmitted to the monitoring center in real time, realizing real-time monitoring of the safety state of the tower.

[0076] S3, analysis and processing: based on the collected tilt data, the transverse inclination and the line inclination of the tower are analyzed and calculated, and based on the transverse inclination and the line inclination, the comprehensive inclination of the tower is analyzed and calculated; based on the collected vibration data, the abnormal vibration of the tower is analyzed and judged; based on the collected elevation data, the settlement deformation of the tower is analyzed and judged.

[0077] Among them, the transverse inclination calculation formula is as follows:

[0086] For example, the line inclination angle reading collected once is 3°, and the transverse line direction inclination angle is 2°.

[0087] Through calculation, the line inclination Gx=tan(3°)×100%≈5.24%, and the transverse inclination=tan(2°)×100%≈3.49%.

[0088] S4, monitoring and early warning: based on the data after various types of analysis and processing, the threshold of each monitoring data is set; if the monitoring data exceeds the threshold range, an early warning signal is triggered, and relevant personnel are reminded in time to take measures to prevent accidents. For example, the threshold is set to ± 5%; through comparative analysis, when the reading of the in-line inclination angle is 3°, the in-line inclination is 5.24%, which exceeds the preset threshold, indicating that the tower exists instability, and measures such as reinforcement need to be taken to deal with it.
