[0032] like Figure 1-Figure 4 As shown, a depth measuring device for exploring mining goafs comprises a base 1; the base 1 is fixedly connected to a mounting frame 2, the mounting frame 2 is rotatably connected to a turntable 10 and a winding roller 7, the turntable 10 is rotatably connected to a connecting assembly 12, the bottom end of the connecting assembly 12 is fixedly connected to a reflecting plate 15, and the reflecting plate 15 is connected to a detection assembly; the winding roller 7 is fixedly connected to a fixing rope 11, the other end of the fixing rope 11 is fixedly connected to the lowermost end of the connecting assembly 12; the mounting frame 2 is fixedly connected to a motor 5 via a mounting seat 4, the turntable 10 is fixedly connected to the output shaft of the motor 5, and the winding roller 7 is connected to the output shaft of the motor 5 via a transmission belt 8.

[0033] More specifically, the mounting frame 2 is provided with a positioning groove 9, the connecting plate 121 is slidably connected to the positioning groove 9, the mounting frame 2 is fixedly connected with a distance sensor 14, and the distance sensor 14 is located above the reflecting plate 15; the mounting frame 2 is provided with a control module 3, the motor 5 and the distance sensor 14 are both electrically connected to the control module 3; the distance sensor 14 is used to detect the distance between it and the reflecting plate 15.

In a specific embodiment, when the adjacent surfaces of any two groups of adjacent connection plates 121 completely overlap, the two can only rotate relative to each other in a specified direction, and at the same time, due to the cooperation between the connection assembly 12 and the fixing rope 11, the effective action section of the connection assembly 12 is always in a straight line state, and under the support of gravity, its stability is further increased.

[0035] More specifically, the base 1 is fixedly connected to a battery 13, the mounting frame 2 is fixedly connected to a solar panel 6, the control module 3, the motor 5, the solar panel 6 and the distance sensor 14 are all electrically connected to the battery 13; the solar panel 6 can charge the battery 13, thereby powering various components, achieving the effect of saving energy.

[0036] like Figure 5 As shown, the detection component includes a sliding column 16, the upper part of the sliding column 16 is fixedly connected to the reflective plate 15, and the lower part is fixedly connected to the pressure sensor 19; the sliding column 16 is slidably connected to a sliding sleeve 17, and a pressure spring 20 is provided between the sliding sleeve 17 and the pressure sensor 19, and the sliding sleeve 17 is provided with a camera 21, a battery 22 and a lamp post 25; the pressure spring 20 has a buffering effect, and the pressure sensor 19 is used to detect the size of the resistance exerted on the protective plate 18 of the device, and the detection component is used to detect the internal environment of the goaf, and the lamp post 25 provides a light source for the surrounding environment.

[0040] The working principle of a depth measuring device for mining goaf exploration provided by the utility model is described below:

[0041] When the utility model provides a depth measuring device for exploring a goaf in a mine, the device is first fixed at a suitable position by a fixing rod 28, so that the detection component is located above the goaf to be investigated, and the motor 5 is started by the control module 3 to drive the winding roller 7 and the turntable 10 to rotate, thereby controlling the connection component 12 and the fixing rope 11 to move downward at the same time. Due to the cooperation between the positioning groove 9 and the fixing rope 11, the connection component 12 located below the positioning groove 9 can only move in a straight line as a whole. During this process, the staff can observe the environment in the goaf in real time through digital devices, and can turn off the motor 5 at any time for careful observation. When the protective plate 18 contacts the bottom of the goaf, the bottom of the goaf generates pressure on the protective plate 18, and then the protective plate 18 generates pressure on the sliding sleeve 17. The sliding sleeve 17 generates pressure on the pressure sensor 19 through the pressure spring 20. The pressure sensor 19 transmits the corresponding signal to the control module 3 through Bluetooth. The control module 3 turns off the motor 5 so that the connection component 12 no longer moves downward, which not only ensures the effectiveness of the depth measurement, but also provides an effective protection effect for the device.

[0042] In summary, the utility model provides a depth measuring device for exploring mining goaf areas. The motor 5 is started by the control module 3 to drive the winding roller 7 and the turntable 10 to rotate, thereby controlling the connecting component 12 and the fixed rope 11 to move downward at the same time. During this process, the staff can observe the environmental conditions in the pit in real time through the camera 21. When the protective plate 18 contacts the bottom of the pit, the pressure sensor 19 transmits the corresponding signal to the control module 3, and the control module 3 can turn off the motor 5 so that the connecting component 12 no longer moves downward, thereby ensuring the effectiveness of the depth measurement.
