Background technology
Refuge chamber is to take place when disaster, when personnel can't withdraw from, and the shelter that invasion and attack poisonous for preventing, pernicious gas are set up.In the self-rescue of miner, it is very necessary that refuge chamber is set.Because self-rescuer is shorter effective time, after wearing self-rescuer, in its effective acting time, can not arrive safety place or route of withdrawal can't through the time, self-rescuer is perhaps arranged and pernicious gas content when higher, refuge chamber can play a role.
Oxygen supply in the refuge chamber is the most key; At present; There are following shortcoming in existing colliery refuge chamber or survival capsule oxygen supply device: 1. down-hole oxygen supply mode major part is carried out through the mine compressed air system, needs driven by power, when emergency takes place; General power supply can suffer corrupted, and oxygen supply purpose does not like this reach; 2. the oxygen supply device oxygen-supplying amount is not accurately measured, and regulative mode is simple, and deficiency or waste appear in oxygen supply process unavoidably; 3. apparatus of oxygen supply is generally single channel control, in case single loop damages, then can't reach the oxygen supply purpose.
Summary of the invention
Be technical deficiency more than solving, it is a kind of simple in structure that the utility model provides, and control accuracy is high, safe colliery refuge chamber or survival capsule oxygen supply self-con-tained unit based on the PID adjusting.
The utility model is realized through following measure:
A kind of colliery refuge chamber or survival capsule oxygen supply automatic control dress of regulating based on PID of the utility model
Put; Comprise oxygen supply electromagnetic valve, PID controller and oxygen concentration sensor that compressed oxygen cylinder and signal connect; Said compressed oxygen cylinder is connected with ventilation channel; The oxygen supply electromagnetic valve is arranged on the ventilation channel, and said oxygen concentration sensor is used in the sensing chamber oxygen concentration and sends signal to the PID controller, and said PID controller sends to oxygen supply electromagnetic valve aperture control signal after with the oxygen concentration signals computing.
Above-mentioned ventilation channel is connected with the assist control pipeline between oxygen supply electromagnetic valve inlet end and outlet side, said assist control pipeline is provided with stop valve and reducing valve, can control by two-way, improves reliability.
Preferably, above-mentioned ventilation channel end is provided with flow meter and silencing means.
In order to make things convenient for demonstration information, above-mentioned PID controller signals is connected with display screen.
The beneficial effect of the utility model is:
1. urgent thing taking place under coal mine, do not have under the extraneous situation of supplying power and still can use, has guaranteed oxygen supply, safe.2. regulating oxygen-supplying amount through PID can accurately control, and can not produce the not enough or waste of oxygen supply.3. adopt double loop control,, can also use other control loop, increased reliability in case a loop is damaged.4. according to actual conditions, can arbitrarily adjust the quantity of compressed oxygen cylinder.5. there is silencing means at the place, gas outlet, and the noise when gas is discharged reaches human body and accepts requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. compressed oxygen cylinder, 2. reducing valve I, 3. stop valve I, 4. strainer, 5. stop valve II, 6. stop valve III, 7. reducing valve II, 8. oxygen supply electromagnetic valve, 9. one way valve, 10. flow meter, 11. silencing means, 12.PID controller, 13. oxygen concentration sensors, 14. display screens, 15. stop valve IV, 16. reducing valve III.
The specific embodiment
As shown in Figure 1; A kind of colliery refuge chamber or survival capsule oxygen supply self-con-tained unit of regulating based on PID of the utility model; Comprise compressed oxygen cylinder 1, oxygen supply electromagnetic valve 8, PID controller 12 and oxygen concentration sensor 13, wherein oxygen supply electromagnetic valve 8, PID controller 12 and oxygen concentration sensor 13 signals are connected, and compressed oxygen cylinder 1 is connected with ventilation channel; Oxygen supply electromagnetic valve 8 is arranged on the ventilation channel, and the oxygen-supplying amount of pipeline is supported in the aperture size control of oxygen supply electromagnetic valve 8.Oxygen concentration sensor 13 is used in the sensing chamber oxygen concentration and sends signal to PID controller 12, and PID controller 12 sends to oxygen supply electromagnetic valve 8 aperture control signals after with the oxygen concentration signals computing.
Particularly; Several places, compressed oxygen cylinder 1 gas outlet are provided with reducing valve I 2 and stop valve I 3; Ventilation channel is connected on through threeway on the air inlet port of gas outlet and stop valve I 3 of reducing valve I 2; Strainer 4 is set on the ventilation channel then, and strainer 4 rears are provided with stop valve IV 15, reducing valve III 16, oxygen supply electromagnetic valve 8, one way valve 9, flow meter 10, at the ventilation channel end silencing means 11 are set.Ventilation channel is connected with the assist control pipeline between oxygen supply electromagnetic valve 8 inlet ends and outlet side simultaneously, and the assist control pipeline is provided with stop valve III 6 and reducing valve II 7, can control by two-way, improves reliability.In order to make things convenient for demonstration information, above-mentioned PID controller 12 signals are connected with display screen 14.
Its operating principle is: system is through the interior oxygen actual concentrations of oxygen concentration sensor 13 sensing chamber (cabin); According to comparing, utilize 12 pairs of oxygen supply electromagnetic valves 8 of PID controller to regulate through the oxygen density value of setting in display screen 14 and the actual oxygen concentration of detection; When detected value is lower than setting value, increase the electromagnetic valve aperture, the oxygen in the compressed air of high flow is through pipeline oxygen supply in refuge chamber; When detected value reached or be higher than setting value, PID controller 12 kept or reduces the aperture of oxygen supply electromagnetic valve 8, to reduce current oxygen-supplying amount.Closed loop PID through oxygen concentration regulates, and has promptly guaranteed the precision of oxygen concentration control, has saved the consumption of oxygen again, has reached the better controlling effect.When electronic pipeline lost efficacy, can open the assist control pipeline, oxygen-supplying amount is as required regulated the outlet flow meter and is quantitatively controlled, and reaches the oxygen supply purpose.This installs main ventilation channel and need not power supply, and oxygen sensor, controller are by the power supply of flame-proof type intrinsic safety electric source, and power consumption is very little, provides battery for oneself and can satisfy fully.
The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection domain of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
