[0002] DCS control interlocking means that in a distributed control system (DCS), devices can be interlocked by inputting interlocking functions. When the interlocking conditions are met, the system will trigger corresponding actions according to the pre-set interlocking relationship.

[0003] An oxygen compressor is a compressor specifically used to compress oxygen. The DCS control realizes the interlocking of the vehicle's oxygen compressor. This is done through a DCS control system that pre-sets a specific working process for the oxygen compressor. In the event of an unexpected accident, it will automatically stop or perform other auxiliary operations. That is, the oxygen compressor as a whole adopts an intelligent and automated working control mode.

[0004] For example, the public document with application number 201721438843.5 discloses an oxygen compressor dedicated to oxygen production. This utility model utilizes a vortex head to solve the shortcomings of a piston oxygen compressor, and has the remarkable characteristics of simple structure, safe and reliable use, and low maintenance costs. However, the heat dissipation effect of this oxygen compressor is relatively weak, which can easily cause thermal overload of the oxygen compressor, causing overheating and overload of the internal electrical components of the oxygen compressor, thereby causing accidents of spontaneous combustion and destruction, which is very dangerous.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a DCS control is proposed to realize the oxygen compressor of the interlocking vehicle. Utility Model Content

[0024] By adopting the above technical solution, the interior of the oxygen compressor body 1 can be quickly inspected and repaired by rotating the sealing plate 2 to open and close.

[0025] The fire extinguishing mechanism 5 can automatically complete the fire extinguishing work, avoiding the serious economic losses caused by the failure to put out the fire in time when no one is watching;

[0026] The cooling mechanism 6 is used to cool the interior of the oxygen compressor body 1, thereby effectively preventing the oxygen compressor body 1 from overheating and overloading, and also reducing the possibility of spontaneous combustion and fire.

[0027] Furthermore, the fire extinguishing mechanism 5 includes a filling box 501 fixedly arranged above the inner surface of the oxygen compressor body 1 , and a feeding port 502 is opened above the surface of the filling box 501 .

[0028] By adopting the above technical solution, the fire extinguishing agent can be repeatedly added to the inside of the filling box 501 through the feeding port 502.

[0029] Furthermore, the fire extinguishing mechanism 5 also includes a movable plate 503 rotatably arranged on the left and right sides of the surface of the filling box 501, and the opposite end of the movable plate 503 extends above the surface of the filling box 501, and tension springs 504 are fixedly installed on the front and rear sides, and the upper end of the tension spring 504 is fixedly connected to the outer surface of the filling box 501.

[0030] By adopting the above technical solution, the movable plate 503 is the bottom closing plate of the filling box 501 to prevent the fire extinguishing agent from leaking;

[0031] The tension spring 504 can pull the movable plate 503 to rotate and open downward on both sides, so that the bottom of the filling box 501 is opened, allowing the fire extinguishing agent to fall and be released.

[0032] Furthermore, the fire extinguishing mechanism 5 also includes a hook plate 505 fixedly installed below the surface of the movable plate 503 , and a traction rope 506 is sleeved and connected between the hook plates 505 .

[0033] By adopting the above technical solution, the traction rope 506 connects the hook plates 505 on both sides, so that the movable plate 503 is pulled horizontally closed through the hook plates 505 to stably block the bottom of the filling box 501.

[0034] Furthermore, the cooling mechanism 6 includes a suction pump 601 fixedly installed at the lower right side of the outer surface of the oxygen compressor body 1, and the air inlet end of the suction pump 601 penetrates the oxygen compressor body 1 and extends to the inside.

[0035] By adopting the above technical solution, the suction pump 601 can suck the hot air inside the oxygen compressor body 1.

[0036] Furthermore, the cooling mechanism 6 also includes a one-way valve pipe 602 fixedly connected to the upper exhaust end of the suction pump 601, a water tank 603 fixedly provided at the upper end of the one-way valve pipe 602, and the water tank 603 is fixedly connected to the surface of the oxygen compressor body 1.

[0037] By adopting the above technical solution, coolant is injected into the water tank 603, and the sucked hot air is discharged into the water tank 603 through the one-way valve pipe 602, and is cooled by contact with the coolant.

[0038] Furthermore, the cooling mechanism 6 also includes a drain pipe 604 arranged on the rear side below the surface of the water tank 603, a water inlet 605 arranged on the front side above the surface of the water tank 603, an exhaust pipe 606 fixedly connected to the rear side above the surface of the water tank 603, and the upper end of the exhaust pipe 606 is connected to the upper part of the interior of the oxygen compressor body 1.

[0039] By adopting the above technical solution, the water inlet 605 can fill the water tank 603 with coolant, and the drain pipe 604 can discharge and replace the coolant;

[0040] The exhaust pipe 606 inputs the cooled air into the oxygen compressor body 1 for a second time, thereby utilizing the cooled air to cool the internal working components.

[0041] Working principle: When using the DCS control to realize the oxygen compressor of the interlocking vehicle, first, add cooling water to the water tank 603 through the water injection port 605, and the water injection port 605 can be closed by a sealing plug. Then, open the sealing plate 2, use the traction rope 506 to pull through the hook plates 505 on both sides, and horizontally close the bottom end of the filling box 501 with the movable plate 503, and then fill the filling box 501 with fire extinguishing agent through the charging port 502. When the oxygen compressor body 1 is working, start the suction pump 601 synchronously, and the suction pump 601 extracts the air inside the oxygen compressor body 1, and transports it upward into the water tank 603 through the one-way valve pipe 602, so that the hot air and the cooling air are mixed. The cooled air will be transported to the upper part of the interior of the oxygen compressor body 1 through the exhaust pipe 606, and the cycle will continue, thereby cooling the interior of the oxygen compressor body 1. If the internal components of the oxygen compressor body 1 that has been working for a long time are overloaded and short-circuited and catch fire, the flames will jump upward and fuse the traction rope 506. The movable plate 503 loses the restriction of the traction rope 506 through the hook plate 505, so that under the pulling force of the tension spring 504, the movable plate 503 is rotated to both sides below and opened, so that the bottom of the filling box 501 is opened, and the internal fire extinguishing powder is sprinkled, thereby extinguishing the fire. This is the working principle of the oxygen compressor of the DCS controlled interlocking vehicle.
