Description

Technical Field

[0001] This utility model relates to the field of downhole tool technology, and in particular to a route-type filling and top-connection shutdown alarm system. Background Technology

[0002] The access-type cemented backfill mining method uses large trackless equipment such as drilling rigs and loaders to carry out ore mining and panel transportation, effectively improving mining efficiency. This method employs a segmented mining-immediate cemented backfilling approach, dividing the ore body into narrow strip access routes. After mining one route, the goaf is immediately filled with backfill material, which serves as an artificial pillar to support the surrounding rock. In underground operations, the timeliness of stopping the access backfilling process directly affects the backfilling and roof connection effect. Currently, the distance between the backfill liquid level and the access roof is judged by the experience of the operators, and a stop signal is issued to the vehicles performing access backfilling. The timeliness of stopping the vehicles during access backfilling is greatly affected by human factors, directly impacting the backfilling and roof connection effect. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an inlet-type filling and roof-connection parking alarm system, which solves the problem that in the existing filling process, the distance between the filling liquid level and the inlet roof plate is usually judged by the experience of the operators, which is greatly affected by human factors and seriously affects the filling and roof-connection effect.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A road-entry filling and roof-connection parking alarm system includes a detection component installed on the roadway roof and a controller installed outside the filling retaining wall. The detection component includes an infrared transmitter and a photodetector arranged opposite each other, and an integrated circuit component located in the middle. The signal input terminal of the infrared transmitter is connected to a power supply, and the signal emitted by the signal output terminal of the infrared transmitter is received by the signal input terminal of the photodetector. The signal output terminal of the photodetector is electrically connected to the signal input terminal of the integrated circuit component. The signal output terminal of the integrated circuit component is connected to the input terminal of the controller through a signal line, and the output terminal of the controller is connected to the input terminal of the alarm.

[0005] Furthermore, the integrated circuit component includes a signal processing circuit and an output circuit. The signal input terminal of the signal processing circuit is electrically connected to the signal output terminal of the photodetector, and the signal output terminal of the signal processing circuit is electrically connected to the signal input terminal of the output circuit. The signal output terminal of the output circuit is connected to the input terminal of the controller via a signal line.

[0006] Furthermore, several detection components are provided on the top plate of the access route.

[0007] Furthermore, three detection components are provided, respectively located at the material inlet, the middle, and the position near the filling retaining wall on the top plate of the inlet.

[0008] Furthermore, the detection component is encased in a shell, which is made of infrared-transparent material.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The infrared transmitter of the detection component installed on the top plate of the access road in this invention emits a signal that is received by a photoelectric detector and then processed by an integrated circuit component. The processed signal is then transmitted to the controller, which monitors the distance between the filling liquid level and the top plate in real time. When the distance between the filling liquid level and the top plate reaches a predetermined value, the controller's alarm sounds and issues a timely shutdown warning, thereby effectively improving the roof contact rate of the underground mining access road and better realizing the roof contact warning of the access road, ensuring the overall safety and stability of the mining area, and providing technical support for the shutdown warning of mines using access road filling mining.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] like Figure 1-3As shown, an approach-type filling and top-mounted parking alarm system includes a detection component 5 installed on the approach top plate 12 and a controller 9 installed outside the filling retaining wall 8. The detection component 5 includes an infrared transmitter 1 and a photodetector 2 arranged opposite each other, and an integrated circuit component 3 located in the middle. The signal input terminal of the infrared transmitter 1 is connected to a power source, and the infrared transmitter 1 converts the electrical signal into an infrared light signal. The signal emitted by the signal output terminal of the infrared transmitter 1 is received by the signal input terminal of the photodetector 2. The infrared signal emitted by the infrared transmitter 1 is received by the photodetector 2. The signal output terminal of the photodetector 2 is electrically connected to the signal input terminal of the integrated circuit component 3. The photodetector 2 receives the infrared signal emitted by the infrared transmitter 1, converts it into an electrical signal, and transmits it to the integrated circuit component for electrical signal processing. The signal output terminal of the integrated circuit component 3 is connected to the input terminal of the controller 9 through a signal line 6. The electrical signal processed by the integrated circuit component 3 is directly transmitted to the controller 9. The output terminal of the controller 9 is connected to the input terminal of the alarm 12. The controller 9 transmits the electrical signal to the alarm, and the alarm sounds.

[0016] The integrated circuit component 3 includes a signal processing circuit and an output circuit. The signal input terminal of the signal processing circuit is electrically connected to the signal output terminal of the photodetector 2. The signal processing circuit processes the electrical signal converted by the photodetector 2 and outputs a usable electrical signal that meets the requirements of subsequent circuits. The signal output terminal of the signal processing circuit is electrically connected to the signal input terminal of the output circuit. The usable electrical signal output by the signal processing circuit is transmitted to the output circuit for output. The signal output terminal of the output circuit is connected to the input terminal of the controller 9 through the signal line 6. The output circuit transmits the electrical signal to the controller 9 through the signal line 6.

[0017] The top plate 12 of the access road is equipped with several detection components 5, which can measure the distance between the top plate of the access road and the filling liquid level at multiple points, ensuring the authenticity of the measurement data.

[0018] Three detection components 5 are provided, respectively located at the discharge port, the middle, and the position near the filling retaining wall of the top plate 12 of the inlet. During use, setting the detection components 5 at the discharge port, the middle, and the position near the filling retaining wall of the top plate 12 of the inlet will have the best effect.

[0019] The detection component 5 is encased in an outer shell made of infrared-transparent material to ensure that the infrared light emitted by the infrared emitter 1 is not affected by the outer shell.

[0020] In use, install the detection component 5 at the feed inlet of the inlet top plate, the middle of the inlet top plate, and near the filling retaining wall of the inlet top plate. Adjust the position and number of the detection components according to the length of the inlet. Then connect the detection component 5 to the controller 9 using the signal line 6. After placing the controller 9 outside the filling retaining wall 8, turn on the power switch 10. After the detection component 5 is powered on, the infrared transmitter 1 converts the electrical signal into an infrared signal and emits it. The emitted infrared signal is reflected back to the inlet top plate after encountering the filling liquid level. The photoelectric detector 2 receives the infrared signal reflected back to the inlet top plate and connects it to the receiving liquid. The infrared signal emitted by the infrared transmitter 1 is received and converted into an electrical signal, which is then transmitted to the signal processing circuit of the integrated circuit component for processing. The circuit outputs a usable electrical signal that meets the requirements of the subsequent circuit and transmits it to the output circuit for output. The output circuit transmits the electrical signal to the controller 9 through the signal line 6. The controller 9 transmits the electrical signal to the alarm to monitor the distance from the filling liquid level to the top plate of the inlet in real time. When the alarms 12 installed at the three locations of the inlet top plate discharge port, the middle of the inlet top plate, and the inlet top plate near the filling retaining wall all start to alarm, the ground filling station is contacted to stop.

[0021] The detection component and controller of this utility model monitor the distance between the filling liquid level and the roof of the access road in real time. When the distance between the filling liquid level and the roof reaches a predetermined value, the alarm of the controller will sound and issue a stop warning in time, thereby effectively improving the filling roof connection rate of the underground mining access road and better realizing the filling roof connection warning of the access road mining area.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
