[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Example 1

[0029] A personnel safety detection device for an inclined shaft track transportation system, combined with an attached Figure 1-2 As shown in Figure 4, the system includes a mounting base 1, a safety detection mechanism, and a positioning wristband 5. Mounting holes 6 are provided at each corner of the bottom surface of the mounting base 1. Anchor bolts pass through the mounting holes 6 and are connected to the ground. After the mounting base 1 is installed on one side of the track, a support rod 2 is provided on the top surface. The safety detection mechanism includes a camera 3 and a receiver 4. The camera 3 and the receiver 4 can be detachably installed at different heights on the support rod 2 through a limiting mechanism.

[0030] The limiting mechanism includes a limiting sleeve, an equipment box 7, and a connector. After the limiting sleeve is placed on the support rod 2, it is fixed by a locking mechanism. The equipment box 7 is fixedly installed on one side of the limiting sleeve. After one side of the equipment box 7 is opened, it is sealed by a cover plate 8. The receiver 4 and the processor are both installed in the equipment box 7. The other side of the limiting sleeve is provided with a connector for adjusting the tilt angle of the camera 3.

[0031] After the positioning wristband 5 is worn on the wrist of the transport personnel, it sends a signal to the receiver 4. With the cooperation of the processor, the distance between the transport personnel and the track is determined. After the wristband is activated, it continuously sends a signal to the receiver 4. After the receiver 4 receives the signal, the processor calculates the distance between the personnel and the track by combining the signal strength and the time difference.

[0032] Example 2

[0033] Based on Example 1, combined with Appendix Figure 3 and 5 As shown, the locking mechanism includes a locking plate 9 and a locking bolt 10; the limiting sleeve includes a first arc plate 11 and a second arc plate 12. After the first arc plate 11 and the second arc plate 12 are hinged together, the other end is connected to the locking plate 9 respectively. After the limiting sleeve is placed around the support rod 2, the two locking plates 9 are pressed tightly against each other, and the locking bolt 10 passes through the two locking plates 9 and is fastened by the nut.

[0034] The support rod 2 has a limiting groove 13, and multiple limiting grooves 13 are arranged sequentially from top to bottom. After the limiting sleeve is placed around the support rod 2, the inner wall is provided with a limiting protrusion 14 that can be inserted into any of the limiting grooves 13, thereby improving the stability of the limiting sleeve installation.

[0035] The connector includes a U-shaped plate 15, a fixed rod 16, and a rotating sleeve 17. After the U-shaped plate 15 is fixedly connected to the limiting sleeve in the center, the fixed rod 16 is vertically arranged inside. The rotating sleeve 17 is rotatably arranged in the center of the fixed rod 16 and fixedly connected to the camera 3. The fixed rod 16 is provided with elastic balls 18. The rotating sleeve 17 is provided with multiple adjustment through holes 19 that cooperate with the elastic balls 18. By cooperating with the U-shaped plate 15 and the rotating sleeve 17, the camera 3 is rotated to the optimal shooting angle, and the elastic balls 18 are locked after being inserted into the adjustment through holes 19.

[0036] In a specific implementation of this utility model, the mounting base 1 is placed at a suitable position on the ground on one side of the track, and the mounting base 1 is firmly fixed to the ground by using anchor bolts passing through the mounting holes 6;

[0037] Select a suitable limiting groove 13 on the support rod 2, install the limiting sleeve, install the receiver 4 and processor in the equipment box 7, connect the power supply and data cable, and complete the system initialization; through the cooperation of the U-shaped plate 15 and the rotating sleeve 17, rotate the camera 3 to the best shooting angle, and lock the elastic ball 18 after it is inserted into the adjustment through hole 19.

[0038] Before entering the inclined shaft work area, the transport personnel wear positioning wristbands 5. After the wristbands are activated, they continuously send signals to receivers 4. After receiving the signals, the processor of receivers 4 calculates the distance between the personnel and the track by combining the signal strength and the time difference.

[0039] Camera 3 captures video of the track area to help identify personnel behavior. If the system determines that a person is approaching a dangerous area (such as a moving mine car), it will immediately trigger an alarm. The alarm information can be notified to relevant personnel through audible and visual alarms, display screen prompts, or remote communication. At the same time, the system can link the transportation control system to brake in an emergency according to the set rules to avoid accidents.

[0040] When maintenance is required, loosen the locking bolt 10, remove the limit sleeve and the equipment box 7; open the cover plate 8 of the equipment box 7, check the operating status of the receiver 4, processor, camera 3 and other equipment, and clean the lens of the camera 3 to prevent dust from obstructing the recognition effect.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
