Description

Self-rescuer with lamplight induced by distance

Technical Field

The invention belongs to the technical field of metal and nonmetal underground mine underground operation safety equipment, and particularly relates to a self-rescuer with lamplight being subjected to distance sensing.

Background

Along with the rapid increase of economy in China, the safety production problem is concerned more and more. The tenth entry in the safety regulations of coal mines is to wear safety helmets, carry self-rescuers and miner lights, forbid carrying tobacco and ignition articles, forbid wearing chemical fiber clothes and forbid drinking before entering the well. Because the self-rescuer has certain weight and is inconvenient for production operation, in the actual production process, the working point of a worker is too far away from the self-rescuer, the carrying effect cannot be achieved, and certain unsafe behaviors of people exist, so that the underground worker cannot use the self-rescuer in time under emergency conditions of water permeation, poisoning suffocation and the like, and further accidents are further worsened to bring a series of serious consequences. The miner lamp and the self-rescuer are necessary equipment for downhole workers, but the miner lamp can achieve necessary effects for downhole operators in the past process, but the self-rescuer is often overlooked easily, and even if the self-rescuer is brought into the well, the self-rescuer cannot be carried about during operation due to inconvenience in operation.

the active radio frequency card 2 is inserted into the radio frequency card slot of the lower cavity.

The miner's lamp 23 can be fixed on the self-rescuer or the safety helmet can be worn.

The self-rescuer host is an isolated self-rescuer host, and the self-rescuer host is a compressed oxygen host.

The flame-retardant plastic shell is divided into an upper cavity and a lower cavity by a middle partition plate, the self-rescuer main body is positioned in the upper cavity, and the storage battery 1 and the miner lamp 23 are arranged in the lower cavity. As shown in fig. 1, the upper chamber comprises a hook 4, a pressure cap 5, a support 6, an oxygen cylinder 7, an exhaust valve 8, a pressure reducing valve 9, a switch knob 10, a safety cap 11, a switch 12, a pressure gauge 13, an observation window 14, a breather valve 16, a mouthpiece 17, a nose clip 18, an air bag 19, an air supply pressure plate 20, a cleaning tank 21, a breathing hose 15, an adjusting screw, a radio frequency card slot and an active radio frequency card 2; the lower cavity body specifically comprises the following components, including a storage battery 1 (containing a storage battery charger), a head-wearing miner lamp 23 (containing a microcontroller 22, a control circuit, a controlled lamp bead driving circuit, a lithium battery, a charging and discharging protection circuit of the lithium battery and a radio frequency communication circuit), and a miner lamp charger 3.

The miner's lamp 23 communicates with the active radio frequency card 2 (tag card) installed on the self-rescuer through a radio frequency communication circuit; the distance between the miner lamp 23 and the self-rescuer is obtained by estimating the signal intensity of the tag card by the microcontroller 22 in the miner lamp 23 through controlling the radio frequency communication circuit; before use, the miner lamp 23 controls the radio frequency communication circuit to receive and read the tag card tag installed on the nearest self-rescuer through the microcontroller 22 to complete binding, the distance between the miner lamp 23 and the bound self-rescuer is detected during use, and after the signal intensity is lower than a certain threshold value, the microcontroller 22 controls the lamp bead driving circuit to reduce the lamp bead driving current to reduce the lamp bead brightness. The miner lamp 23 is bound with the corresponding self-rescuer radio frequency tag, so that mutual interference between a plurality of self-rescuers and the miner lamp 23 is avoided.

The miner's lamp 23 is controlled by the microcontroller 22, and the light is gradually extinguished when the person is too far away from the self-rescuer, so that the worker can carry the miner's lamp; the miner's lamp 23 can be fixed on the self-rescuer or the safety helmet; the active RFID card assembled on the self-rescuer has low power consumption and high reliability, does not need to be disassembled for maintenance in the validity period of the self-rescuer, and can be disassembled to replace a battery for repeated use after the self-rescuer expires; the miner lamp 23 adopts a constant-current lamp bead driver for supplying power, so that the stable brightness of the lamp beads can be ensured, and the service life of the lamp beads can be prolonged; the storage battery can provide power for the miner lamp in case of accidents, and the service time of the miner lamp is greatly prolonged.

Before the device is used, whether the pressure of the pressure gauge 13 is over-pressure or under-pressure is checked through the observation window 14, and the device can be carried for downhole operation after error-free check. The miner's lamp 23 and the self-rescuer are detachable, and if the position of the miner's lamp is inconvenient in the operation process, the miner's lamp 23 can be detached from the lower shell of the self-rescuer and is installed on the safety helmet. The self-rescuer needs to be carried about in the operation process, and once the distance exceeds two meters, the miner lamp is gradually extinguished. If the electric quantity of the miner lamp 23 is insufficient, the miner lamp 23 can be connected with the self-rescuer storage battery 1 for charging. When the self-rescuer is needed to be used under special conditions, the upper cover of the self-rescuer is firstly opened, the nose clip 18 clamps the nose, the mouth tool 17 is contained in the mouth, the switch of the self-rescuer is opened, and the air supplement pressure plate 20 can be lightly pressed to supplement air under the condition that the air bag 19 is lack of oxygen. After the working personnel lift the well, the self-rescuer is handed to a special person for storage, and the storage personnel need to carry out daily charging and maintenance on the self-rescuer storage battery 1.

The self-rescuer with distance-induced light combines the miner's lamp 23 and the self-rescuer together, once the linear distance between the self-rescuer and the miner's lamp 23 exceeds two meters, the light of the miner's lamp 23 can receive a signal to react, the light has the brightest effect within two meters of the linear distance between the light and the self-rescuer, and once the distance exceeds two meters, the miner's lamp gradually becomes dark from the brightest along with the increase of the distance until the light completely disappears, thereby ensuring that an operator can carry the self-rescuer with him. Meanwhile, the self-rescuer is internally provided with a storage battery, so that the service time of the miner lamp is greatly prolonged in emergency, and long-time illumination conditions are provided for underground personnel.
