Description

Technical Field

[0001] This utility model relates to the field of downhole safety protection technology, specifically to a novel protective suit based on safety airbags to prevent ground pressure. Background Technology

[0002] Currently, rockburst protection devices have low strength and small protective areas, making it difficult to cover the entire body and provide sufficient protection for underground workers. Simultaneously, the strength of existing protective clothing safety devices is also low, and the strength of these devices directly determines personnel safety. Existing rockburst protection devices cannot be integrated with underground detection devices. While these devices can monitor rock wall vibrations in real time and provide early warnings of rockburst hazards, they cannot promptly alert underground personnel. This results in severely inadequate protection against rockbursts in coal mines, failing to reduce safety hazards in underground mining and thus remaining a pressing problem that needs to be solved.

[0003] Therefore, to address the aforementioned problems, a novel protective suit against rockbursts is provided to solve current issues and meet current needs. Thus, existing technologies require further improvement and enhancement. Utility Model Content

[0043] Each airbag is equipped with a gas generating device, and the power module is located on the main body 1 of the garment and is connected to the circuit of each gas generating device. Specifically, the gas generating device includes a silicone sheet 41, positive and negative electrodes 42, and a vacuum packaging bag 43. The silicone sheet 41 is embedded in the edge of the corresponding airbag, with its two sides located inside and outside the corresponding airbag, respectively. The outer wall of the silicone sheet 41 is fixedly and sealed to the corresponding airbag.

[0044] The vacuum packaging bag 43 is located inside the corresponding air bladder and is sealed to the silicone sheet 41. It contains powdered sodium azide 44. Positive and negative electrodes 42 are installed at one end of the silicone sheet 41 inside the corresponding air bladder and embedded within the sodium azide 44. The silicone sheet 41 has a circuit socket 411 at the end outside the corresponding air bladder. The vacuum packaging bag 43 is made of a plastic bag with a certain degree of toughness. The powdered sodium azide 44 is sealed inside the vacuum packaging bag 43, isolating it from external air and preventing moisture damage and failure.

[0045] The power module uses a rechargeable lithium battery 52, which is fixed to the right side of the hem of the garment body 1 via a battery box 51. The lithium battery 52 is connected to the circuit sockets 411 of each silicone sheet 41 located on the garment body 1 via wires. The lithium battery 52 is electrically connected to the circuit sockets 411 at the ends of the silicone sheets 41 via wires passing through the inner layers of the garment body 1 and the trouser body 2. The controller controls the positive and negative electrodes 42 to be energized or de-energized via signal commands.

[0046] The wireless signal transceiver module, data analysis module, and controller are encapsulated inside the first box 8, which is fixed to the left side of the lower hem of the upper garment body 1. The wireless signal transceiver module and data analysis module are respectively connected to the controller for communication. The wireless signal transceiver module is respectively connected to the micro-vibration sensor of the rock strata in the coal mine and the signal of the underground network pipe. In addition, the wireless signal transceiver module can connect to the wireless signal transceiver modules on other protective clothing in the vicinity.

[0047] A connector 53 is installed at the waistband of the trouser body 2. The connector 53 has a data cable port and a power port for connecting the lithium battery 52. ​​The connector 53 is connected to the circuit port 411 of each silicone sheet 41 on the trouser body 2. The controller controls the positive and negative electrodes 42 of all gas generating devices to conduct electricity through commands.

[0048] The right cuff of the upper garment body 1 is provided with a second box 61. The second box 61 is equipped with a manual switch and a safety switch. The manual switch power supply module is electrically connected to control the positive and negative electrodes 42 of all gas generating devices to conduct electricity. The second box 61 is provided with a cover 62.

[0049] The warning device is mounted on the outer wall of the chest patch 12 and is communicatively connected to the controller. Specifically, the warning device includes an explosion-proof housing 71 and a warning indicator light 72, a distance indicator light 73, a buzzer 74, and a search and rescue mode switch 75 mounted on the explosion-proof housing 71. The warning indicator light 72, distance indicator light 73, and buzzer 74 are communicatively connected to the controller. Under normal conditions, the warning indicator light 72 flashes slowly; under abnormal conditions, the warning indicator light 72 flashes rapidly; and under conditions of rockburst or other danger, the warning indicator light 72 remains constantly lit, reminding personnel to promptly enter a safe area or avoid falling rocks.

[0050] The wireless signal transceiver module of this invention connects to a micro-vibration sensor deployed within the underground rock wall. A data analysis module analyzes the received data to determine if a rockburst has occurred and whether the intensity of the underground vibration will cause the rock wall to break. In the event of a rockburst or collapse, the controller uses a command signal to energize the positive and negative electrodes 42, triggering a reaction in the sodium azide 44 that breaks the vacuum packaging bag 43. The resulting gas fills the corresponding airbags, maintaining all airbags under a certain pressure to protect the wearer from flying debris. In the event of a wireless communication failure underground, the worker wearing the protective suit can activate a manual switch inside the second housing 61 to inflate all airbags.

[0051] After all airbags are inflated, the warning device starts working, the buzzer 74 sounds an alarm, and the distance indicator light 73 lights up to facilitate search and rescue. The distance indicator light 73 emits a corresponding color light according to the distance between the two protective suits. When the distance between the two protective suits is more than 50m, the indicator light is yellow; when the distance between the two protective suits is 10-50m, the indicator light is green; and when the distance is within 10m, the indicator light is blue. At the same time, the flashing frequency of the distance indicator light 73 gradually increases as the distance approaches the critical distance, so that search and rescue personnel wearing the same protective suits can determine the location of the trapped person in time and start the rescue as soon as possible.

[0052] The parts not mentioned in this utility model can be achieved by adopting or referencing existing technologies.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
