Description

Technical Field

[0001] The invention relates to the technical field of oxygenation equipment, and in particular to an oxygen subpackaging bus detection alarm device and an alarm method. Background Art

[0002] Oxygen is a combustion aid and oxidant, which is indispensable in industrial production. Its preparation method is: first liquefy the air to separate the oxygen, then convert the liquid oxygen into gaseous oxygen through a vaporizer, and finally complete the subpackaging of the oxygen cylinder through multiple valves on the bus. During traditional subpackaging, the operator transports the empty oxygen cylinder to the room where the bus is located, and then connects the output end of the sub-valve installed on the bus to the interface at the upper end of the oxygen cylinder, opens the main valve and the sub-valve, and the high-pressure oxygen automatically completes the filling and subpackaging of the oxygen cylinder. In the high-pressure oxygen transmission output by the above-mentioned vaporizer, the high-pressure oxygen pipe and the bus are equipped with main valves and sub-valves. These places are all places where oxygen leaks. Once the local oxygen concentration is too high, it is very easy to cause an explosion accident, which not only affects production safety, but also easily causes casualties.

[0003] Patent No. CN 104238585 A is an oxygen sub-packaging bus detection alarm device, including a liquid oxygen tank, a vaporizer and a bus, a main electric control valve is connected in series on the main pipe, and multiple sub-electric control valves are connected in series on the branch pipe. Multiple oxygen concentration sensors are installed on the inner wall of the room where the bus is located, and multiple explosion-proof exhaust fans are also embedded on the inner wall of the room. The main electric control valve, sub-electric control valve, oxygen concentration sensor and explosion-proof exhaust fan are all connected to a central control module. In this invention, the main electric control valve, sub-electric control valve, explosion-proof exhaust fan and oxygen concentration sensor are installed on the bus. The oxygen concentration sensor is responsible for detecting the concentration of oxygen in the environment, and then the data is transmitted back to the central control module, output and displayed on the display module on one side, and transmitted back to the host computer on the other side for storage, analysis or alarm by the host computer. Once the concentration is too high, the central control module automatically starts the explosion-proof exhaust fan to circulate air inside and outside the house, quickly reducing the local oxygen concentration, and effectively ensuring production safety.

[0004] The working principle proposed in the invention mainly relies on a single exhaust fan for air circulation. This design shows some limitations and potential risks in practical applications. First, the design of this exhaust fan system does not fully consider the complexity and variability of air circulation. It only reduces the oxygen concentration in the room by running the exhaust fan, but fails to effectively deal with the differences in air circulation in different environments. The quality and speed of the fan and the actual environment such as temperature, humidity, air pressure and other factors will have a significant impact on the efficiency of the exhaust fan. Secondly, the invention has obvious deficiencies in safety, especially in the working environment, due to operating errors or equipment failures, etc., oxygen leakage may occur. In a larger working environment, when the leaked oxygen does not reach a certain concentration, it is difficult to be detected quickly, so it is difficult to quickly and timely send out an alarm message. And when these leaked oxygen are not discharged in time through the exhaust fan, and when they come into contact with a fire source in a complex working environment, it is very easy to cause the risk of explosion. In response to the above problems, the present invention document proposes an oxygen subpackaging bus detection alarm device and an alarm method. Summary of the invention

[0010] The closing structure comprises a closing block slidably connected to the inside of the storage tube, the closing block is rotatably connected to the second connecting frame, and a collecting cover is fixedly connected to the top of the closing block.

[0011] Preferably, the oxygen packaging bus body is connected to the connecting tube through a conduit, an alarm body is installed on the top of the second protective cover, and the bottoms of the first protective cover and the second protective cover are fixedly connected with a mounting shell, and the two mounting shells are fitted together to form a circular ring.

[0012] Preferably, the first connecting frame is located on the top of the second connecting frame, the first connecting frame and the second connecting frame are both slidably connected to the first protective cover, an alarm prompt plate is fixedly connected to the top of the first connecting frame, the alarm prompt plate is located outside the first protective cover, and the second connecting frame is slidably connected to the storage tube.

[0013] Preferably, the telescopic rod and the second spring are both located inside the adjusting sleeve, and the second spring is wound around the outside of the telescopic rod, and a plurality of ventilation holes are provided on the side of the first protective cover near the adjusting sleeve.

[0014] Preferably, a guide base is fixedly connected to the bottom of the closing block, and the shape of the end of the guide base is set to be a truncated cone shape.

[0015] Preferably, a rubber sleeve is fixedly connected to the outer wall of the closing block, and the rubber sleeve is in contact with the inner wall of the storage tube.

[0016] Preferably, the sealing structure includes two adjustment covers fixedly connected to the first protective cover and the outer side of the second protective cover, a movable plate is slidably connected inside the adjustment cover, a sliding rod and a first spring are fixedly connected to the movable plate, an end of the first spring away from the movable plate is fixedly connected to the adjustment cover, an airbag is installed inside the mounting shell, a three-way conduit is installed on the surface of the airbag, and the airbag is connected to the two adjacent adjustment covers through the three-way conduit.

[0017] Preferably, sealing pads are provided on the surfaces of the movable plate and the pushing block, and rubber pads are provided at the connection between the first connecting frame and the first protective cover, and at the connection between the second connecting frame and the storage cylinder.

[0018] An oxygen dispensing bus detection alarm method, applicable to an oxygen dispensing bus detection alarm device as claimed in claims 1-8, comprises the following steps:

[0019] S1. The operator adjusts the electric push rod. When the electric push rod is extended, the second protective cover is pushed away from the first protective cover, so that the first protective cover and the second protective cover are opened. The operator places the tank body that needs to be filled with oxygen into the first protective cover and the second protective cover, so that the air inlet of the tank body is connected to the connecting tube. The operator then adjusts the electric push rod to shrink, so that the second protective cover moves closer to the first protective cover until it fits tightly. When the second protective cover moves closer to the first protective cover, the two threaded tubes on the same side of the first protective cover and the second protective cover squeeze each other, so that the sliding rod pushes the movable plate to move inside the adjustment cover, so that the airbag expands, thereby ensuring that the two airbags are tightly fitted to the adjacent tank body;

[0020] S2. When the oxygen packing bus body inflates the tank body, if there is an air leakage, oxygen will leak into the first protective cover and the second protective cover. When the alarm body detects that the oxygen concentration inside the oxygen packing bus body is high, an alarm message will be issued. As the oxygen concentration inside the first protective cover and the second protective cover becomes higher and higher, the air pressure inside the first protective cover and the second protective cover increases, so that the push block moves closer to the first protective cover inside the adjusting sleeve. When the push block moves, it squeezes the telescopic rod and the second spring, and can push the first connecting frame and the second connecting frame to move away from each other through the two pushing plates. The second connecting frame pushes the closing block to retract into the connecting tube. Under the action of the guide base, the closing block automatically flips over, and the oxygen gas flowing inside the connecting tube can push the collecting cover, so that the rubber sleeve fits against the inner wall of the connecting tube to complete the blockage and closure process. The first connecting frame pushes the alarm prompt plate to move away from the first protective cover, thereby further performing an alarm and reminder function.

[0021] Compared with the prior art, the present invention provides an oxygen packing bus detection alarm device, which has the following beneficial effects:

[0022] 1. The oxygen packing bus detection alarm device is provided with a driving structure and a closing structure. When the oxygen packing bus body inflates the tank body, if there is a gas leakage, oxygen will leak into the first protective cover and the second protective cover, so that the alarm body sends out an alarm. As the oxygen concentration inside the first protective cover and the second protective cover becomes higher and higher, the air pressure inside the first protective cover and the second protective cover increases, so that the push block moves close to the first protective cover inside the adjustment sleeve. When the push block moves, the telescopic rod and the second spring are squeezed, and the first connecting frame and the second connecting frame can be pushed away from each other through two pushing plates. The first connecting frame pushes the alarm prompt plate to move away from the first protective cover, thereby further alarming and reminding. The second connecting frame pushes the closing block to retract into the connecting tube. Under the action of the guide base, the closing block automatically flips, and the oxygen gas flowing inside the connecting tube can push the collecting cover, so that the rubber sleeve fits with the inner wall of the connecting tube. Not only a double-channel alarm process is performed, but also the connecting tube can be automatically blocked and closed to prevent continuous leakage of oxygen, thereby improving the safety of the device.

[0023] 2. The oxygen packing bus detection alarm device, by setting an alarm structure and a sealing structure, the operator places the tank body that needs to be filled with oxygen into the first protective cover and the second protective cover, so that the air inlet of the tank body is connected to the connecting tube, and the operator then adjusts the electric push rod to shrink, so that the second protective cover moves close to the first protective cover until it is tightly fitted. When the second protective cover moves close to the first protective cover, the two threaded tubes on the same side of the first protective cover and the second protective cover squeeze each other, so that the sliding rod pushes the movable plate to move inside the adjustment cover, so that the airbag expands, thereby ensuring that the two airbags are tightly fitted with the adjacent tank body, ensuring the sealing of the internal space of the first protective cover and the second protective cover. When there is an oxygen leakage, the leaked oxygen is collected in the first protective cover and the second protective cover. Since the space inside the first protective cover and the second protective cover is small and closed, the alarm body can detect the abnormal change of oxygen concentration inside the oxygen packing bus body in time, thereby issuing an alarm, and can effectively prevent oxygen from contacting with external fire sources, reduce the risk of explosion, and further improve the safety of the device.

[0024] 3. The oxygen dispensing bus detection alarm device is provided with a fine-tuning structure. When the operator uses the device to inflate the tank body, the threaded barrel can be rotated to move the threaded barrel on the outer wall of the threaded rod. By adjusting the combined length of the threaded rod and the threaded barrel, when the oxygen dispensing bus body is inflated to different types of tank bodies, the two air bags can always fit tightly with the tank body, thereby ensuring the sealing between the first protective cover and the second protective cover after closing.

When the second protective cover 203 moves close to the first protective cover 202, the two threaded tubes 402 located on the same side of the first protective cover 202 and the second protective cover 203 squeeze each other, so that the sliding rod 303 pushes the movable plate 302 to move inside the adjustment cover 301, so that the airbag 306 expands, thereby ensuring that the two airbags 306 are tightly fitted with the adjacent tank body, ensuring the sealing of the internal space of the first protective cover 202 and the second protective cover 203. When there is oxygen leakage, the leaked oxygen is collected in the first protective cover 202 and the second protective cover 203, and it is difficult to discharge, thereby preventing oxygen from leaking to the outside, and avoiding contact with external fire sources, thereby avoiding explosion, and further improving the safety of the device.

[0051] Working principle: The operator rotates the threaded barrel 402 to move the threaded barrel 402 on the outer wall of the threaded rod 401, thereby adjusting the length of the threaded rod 401 and the threaded barrel 402. The operator adjusts the electric push rod 204. When the electric push rod 204 is extended, it pushes the second protective cover 203 to move away from the first protective cover 202, so that the first protective cover 202 and the second protective cover 203 are opened. The operator places the tank body that needs to be filled with oxygen into the first protective cover 202 and the second protective cover 203, so that the air inlet of the tank body is in contact with the connecting barrel 20 5 connection, the operator then adjusts the electric push rod 204 to shrink, so that the second protective cover 203 moves close to the first protective cover 202 until they are tightly fitted. When the second protective cover 203 moves close to the first protective cover 202, the two threaded cylinders 402 located on the same side of the first protective cover 202 and the second protective cover 203 squeeze each other, so that the slide rod 303 pushes the movable plate 302 to move inside the adjustment cover 301, so that the airbag 306 expands, thereby ensuring that the two airbags 306 are tightly fitted with the adjacent tank body;

[0052] When the oxygen dispensing bus body 1 is inflating the tank, if there is a leak, oxygen will leak into the first protective cover 202 and the second protective cover 203. When the alarm body 207 detects that the oxygen concentration inside the oxygen dispensing bus body 1 is high, an alarm message will be issued. As the oxygen concentration inside the first protective cover 202 and the second protective cover 203 becomes higher and higher, the air pressure inside the first protective cover 202 and the second protective cover 203 increases, so that the push block 502 moves closer to the first protective cover 202 inside the adjusting sleeve 501. When the push block 502 moves, the telescopic rod 503 and the second spring 503 are pressed. 4 is squeezed, and the first connecting frame 507 and the second connecting frame 508 can be pushed to move away from each other through the two pushing plates 506, and the second connecting frame 508 pushes the closing block 601 to move into the inside of the connecting cylinder 205.
