An oxygen distribution and manifold detection and alarm device and an alarm method

Abstract

The present invention discloses an oxygen sub-packaging manifold detection and alarm device and an alarm method, and the following solutions are now proposed. It includes an oxygen sub-packaging manifold body and an alarm structure, and a sealing structure and a closing structure are provided on the alarm structure; by setting a driving structure and a closing structure, if there is a gas leakage, oxygen will leak into the inside of the first protective cover and the second protective cover, causing the alarm body to give an alarm. As the oxygen concentration inside the first protective cover and the second protective cover becomes higher and higher, the second connecting frame pushes the closing block to move into the connecting cylinder. Under the action of the guiding base, the closing block automatically flips, and the oxygen gas flowing inside the connecting cylinder can push the collecting cover, so that the rubber sleeve fits with the inner wall of the connecting cylinder. Not only is double-channel alarm processing performed, but also the connecting cylinder can be automatically blocked and closed to hinder the continuous leakage of oxygen, thereby improving the safety of the device.

Description

Technical Field

[0001] The present invention relates to the technical field of oxygen filling equipment, and particularly to an oxygen sub-packaging manifold detection and alarm device and an alarm method. Background Art

[0002] Oxygen is a combustion-supporting agent and an oxidant, which is essential in industrial production. Its preparation method is as follows: First, air is liquefied to separate oxygen, then the liquid oxygen is converted into gaseous oxygen through a vaporizer, and finally the filling of oxygen cylinders is completed through multiple valves on the manifold. During traditional sub-packaging, operators transport empty oxygen cylinders to the room where the manifold is located, then connect the output end of the sub-valve installed on the manifold to the interface at the upper end of the oxygen cylinder, open the main valve and the sub-valve, and the high-pressure oxygen automatically completes the filling and sub-packaging of the oxygen cylinder. During the transportation of the high-pressure oxygen output by the above vaporizer, high-pressure oxygen pipes, the main valve and sub-valves are installed on the manifold, and these are all places where oxygen leakage may occur. Once the local oxygen concentration is too high, an explosion accident is extremely likely to occur, which not only affects production safety but also easily causes casualties.

[0003] An oxygen sub-packaging manifold detection and alarm device with the patent number CN104238585A includes a liquid oxygen tank, a vaporizer and a manifold. 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 sub-pipes. Multiple oxygen concentration sensors are installed on the inner wall of the room where the manifold is located, and multiple explosion-proof exhaust fans are also embedded on the inner wall of the room. The main electric control valve, the sub-electric control valves, the oxygen concentration sensors and the explosion-proof exhaust fans are all connected to a central control module. In this invention, a main electric control valve, sub-electric control valves, explosion-proof exhaust fans and oxygen concentration sensors are installed on the manifold. The oxygen concentration sensors are responsible for detecting the oxygen concentration in the environment, and then the data is transmitted back to the central control module. On the one hand, it is output and displayed on the display module, and on the other hand, it is transmitted back to the upper computer for storage, analysis or alarm by the upper computer. Once the concentration is too high, the central control module automatically starts the explosion-proof exhaust fans to make the air inside and outside the room circulate, quickly reducing the local oxygen concentration and effectively ensuring production safety.

[0004] The working principle proposed by this invention mainly relies on a single exhaust fan for air circulation. This design shows some limitations and potential risks in practical applications. Firstly, this exhaust fan system does not fully consider the complexity and variability of air circulation in its design. It only reduces the oxygen concentration in the room by the operation of the exhaust fan, but fails to effectively cope with the differences in air circulation under different environments. Factors such as the quality, rotation speed of the fan, and the actual environment such as temperature, humidity, air pressure, etc. will have a significant impact on the efficiency of the exhaust fan. Secondly, this invention has obvious deficiencies in terms of safety. Especially in the working environment, due to reasons such as operation errors or equipment failures, oxygen leakage may occur. In a large working environment, when the leaked oxygen does not reach a certain concentration, it is difficult to be detected quickly, thus it is difficult to send out alarm information quickly and in a timely manner. And when this leaked oxygen is not discharged in time through the exhaust fan and comes into contact with a fire source in a complex working environment, it is extremely likely to cause the danger of explosion. In view of the above problems, this invention document proposes an oxygen distribution and manifold detection and alarm device and an alarm method. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose an oxygen distribution and manifold detection and alarm device and an alarm method that not only perform double-channel alarm processing, but also can automatically block and close the connecting cylinder to prevent continuous oxygen leakage, thereby improving the safety of the device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An oxygen distribution and manifold detection and alarm device, comprising an oxygen distribution and manifold body and an alarm structure. A sealing structure and a closing structure are provided on the alarm structure, and a fine-tuning structure is provided on the sealing structure. A driving structure that moves with the air pressure is arranged inside the alarm structure, and the driving structure drives the closing structure;

[0008] The alarm structure at least includes a support frame. A first protective cover is fixedly connected to the support frame, and at least one electric push rod is installed on the top of the first protective cover. A second protective cover is fixedly connected to the movable rod of the electric push rod. A connecting cylinder is detachably installed inside the first protective cover, and a storage cylinder is fixedly connected to the top of the connecting cylinder;

[0009] The driving structure includes an adjustment sleeve fixedly connected inside the first protective cover. A pushing block is slidably connected inside the adjustment sleeve. The side of the pushing block is fixedly connected to the first protective cover through a telescopic rod and a second spring. A connecting rod is fixedly connected to the side of the pushing block away from the telescopic rod, and two pushing plates are rotatably connected to the connecting rod. A first connecting frame and a second connecting frame are respectively rotatably connected to the two pushing plates;

[0010] The closed structure includes a closing block slidably connected inside the storage cylinder. 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 distribution manifold body is interconnected with the connecting cylinder through a conduit. An alarm body is installed on the top of the second protective cover. Mounting shells are fixedly connected to the bottoms of the first protective cover and the second protective cover, and the two mounting shells form an annular shape after being fitted together.

[0012] Preferably, the first connecting frame is located on the top of the second connecting frame. Both the first connecting frame and the second connecting frame are slidably connected to the first protective cover. An alarm prompt board is fixedly connected to the top of the first connecting frame, and the alarm prompt board is located outside the first protective cover. The second connecting frame is slidably connected to the storage cylinder.

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

[0014] Preferably, a guiding base is fixedly connected to the bottom of the closing block, and the shape of the end of the guiding base is a frustum 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 cylinder.

[0016] Preferably, the sealing structure includes two adjusting covers fixedly connected to the outer sides of the first protective cover and the second protective cover. A movable plate is slidably connected inside the adjusting cover. A sliding rod and a first spring are fixedly connected to the movable plate. One end of the first spring away from the movable plate is fixedly connected to the adjusting 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 interconnected with the two adjacent adjusting covers through the three-way conduit.

[0017] Preferably, sealing gaskets are provided on the surfaces of the movable plate and the pushing block. Rubber gaskets 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 distribution manifold detection and alarm method, applicable to an oxygen distribution manifold detection and alarm device, includes the following steps:

[0019] S1. The operator adjusts the electric push rod. When the electric push rod extends, it pushes the second protective cover to move away from the first protective cover, causing the first protective cover and the second protective cover to open. The operator places the oxygen-filled tank body inside the first protective cover and the second protective cover, making the air inlet of the tank body connected to the connecting cylinder. Then the operator adjusts the electric push rod to contract, causing the second protective cover to move closer to the first protective cover until they fit tightly. When the second protective cover moves closer to the first protective cover, the two threaded cylinders on the same side of the first protective cover and the second protective cover squeeze each other, causing the sliding rod to push the movable plate to move inside the adjusting cover, making the airbag expand, so as to ensure that both airbags fit tightly against the adjacent tank body.

[0020] S2. When the oxygen distribution manifold body fills the tank body with gas, if there is a gas leakage, oxygen will leak into the first protective cover and the second protective cover. When the alarm body detects a high oxygen concentration inside the oxygen distribution manifold body, it will send an alarm message. As the oxygen concentration inside the first protective cover and the second protective cover increases, the air pressure inside the first protective cover and the second protective cover increases, causing the push block to move 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 push plates. The second connecting frame pushes the closing block to retract into the connecting cylinder. Under the action of the guiding base, the closing block automatically flips, and the oxygen gas flowing inside the connecting cylinder can push the collecting cover, causing the rubber sleeve to fit against the inner wall of the connecting cylinder to complete the blocking and closing process. The first connecting frame pushes the alarm prompt board to move away from the first protective cover to further give an alarm for reminder.

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

[0022] 1. The oxygen distribution and manifold detection and alarm device, by setting a driving structure and a closing structure, when the oxygen distribution and manifold body inflates the tank body, if there is a leakage, oxygen will leak into the inside of the first protective cover and the second protective cover, causing the alarm body to give 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 inside the adjusting sleeve towards the first protective cover. 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 two push plates. The first connecting frame pushes the alarm prompt board to move away from the first protective cover, so as to further give an alarm and play a reminder role. The second connecting frame pushes the closing block to retract into the connecting cylinder. Under the action of the guiding base, the closing block automatically flips, and the oxygen gas flowing inside the connecting cylinder can push the collecting cover, so that the rubber sleeve fits with the inner wall of the connecting cylinder. It not only performs double-channel alarm processing, but also can automatically block and close the connecting cylinder to prevent the continuous leakage of oxygen, thereby improving the safety of the device.

[0023] 2. The oxygen distribution and manifold detection and alarm device, by setting an alarm structure and a sealing structure, the operator places the tank body that needs to be filled with oxygen inside the first protective cover and the second protective cover, so that the air inlet of the tank body is connected to the connecting cylinder. Then the operator adjusts the electric push rod to contract, so that the second protective cover moves towards the first protective cover until they are closely attached. When the second protective cover moves towards the first protective cover, the two threaded cylinders 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 adjusting cover, causing the airbag to expand, so as to ensure that both airbags are closely attached to the adjacent tank body, ensuring the tightness of the space inside the first protective cover and the second protective cover. When there is an oxygen leakage situation, the leaked oxygen gathers inside 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 is a closed space, the alarm body can detect the abnormal change of the oxygen concentration inside the oxygen distribution and manifold body in time, so as to give an alarm, and can effectively prevent oxygen from contacting with external fire sources, reducing the risk of explosion and further improving the safety of the device.

[0024] 3. The oxygen distribution and manifold detection and alarm device, by setting a fine-tuning structure, when the operator uses the device to inflate the tank body, the threaded cylinder can be rotated to make the threaded cylinder move on the outer wall of the threaded rod. By adjusting the combined length between the threaded rod and the threaded cylinder, when the oxygen distribution and manifold body inflates tank bodies of different models, the two airbags can always be closely attached to the tank body, ensuring the tightness of the closure between the first protective cover and the second protective cover.

By providing the guiding base 602 and setting the shape of the end of the guiding base 602 as a frustum shape, when the second connecting frame 508 pushes the closing block 601 to move into the connecting cylinder 205, under the action of the guiding base 602, the closing block 601 can automatically flip, so that the closing block 601 can block and close the connecting cylinder 205 through the rubber sleeve 604, avoiding the continuous leakage of oxygen, and having a high safety.

[0050] In the present invention, the sealing structure 3 includes two adjusting covers 301 fixedly connected to the outer sides of the first protective cover 202 and the second protective cover 203. A movable plate 302 is slidably connected inside the adjusting cover 301. A sliding rod 303 and a first spring 304 are fixedly connected to the movable plate 302. One end of the first spring 304 away from the movable plate 302 is fixedly connected to the adjusting cover 301. An airbag 306 is installed inside the mounting shell 208. A three-way conduit 305 is installed on the surface of the airbag 306, and the airbag 306 is interconnected with the two adjacent adjusting covers 301 through the three-way conduit 305. Sealing gaskets are provided on the surfaces of the movable plate 302 and the pushing block 502. Rubber gaskets are provided at the connection between the first connecting frame 507 and the first protective cover 202, and at the connection between the second connecting frame 508 and the storage cylinder 206. By providing the first protective cover 202, the second protective cover 203, the adjusting cover 301, the three-way conduit 305 and the airbag 306, the operator places the tank that needs to be filled with oxygen inside the first protective cover 202 and the second protective cover 203, so that the air inlet of the tank is connected to the connecting cylinder 205. Then the operator adjusts the electric push rod 204 to contract, causing the second protective cover 203 to move closer to the first protective cover 202 until they are in close fit. When the second protective cover 203 moves closer to the first protective cover 202, the two threaded cylinders 402 on the same side of the first protective cover 202 and the second protective cover 203 are mutually pressed, so that the sliding rod 303 pushes the movable plate 302 to move inside the adjusting cover 301, causing the airbag 306 to expand, thereby ensuring that both airbags 306 are in close fit with the adjacent tank, ensuring the sealing of the internal space of the first protective cover 202 and the second protective cover 203. When there is an oxygen leakage situation, the leaked oxygen gathers inside the first protective cover 202 and the second protective cover 203 and is difficult to discharge, thus preventing the oxygen from leaking to the outside and avoiding contact with external fire sources, thereby avoiding the occurrence of an explosion situation and further improving the safety of the device.

[0051] Working principle: The operator rotates the threaded cylinder 402 so that the threaded cylinder 402 moves on the outer wall of the threaded rod 401, thereby adjusting the lengths of the threaded rod 401 and the threaded cylinder 402. The operator adjusts the electric push rod 204. When the electric push rod 204 extends, it pushes the second protective cover 203 to move away from the first protective cover 202, causing the first protective cover 202 and the second protective cover 203 to open. The operator places the tank that needs to be filled with oxygen inside the first protective cover 202 and the second protective cover 203, making the air inlet of the tank connected to the connecting cylinder 205. Then the operator adjusts the electric push rod 204 to contract, causing the second protective cover 203 to move closer to the first protective cover 202 until they are closely fitted. When the second protective cover 203 moves closer to the first protective cover 202, the two threaded cylinders 402 on the same side of the first protective cover 202 and the second protective cover 203 are squeezed against each other, causing the slide rod 303 to push the movable plate 302 to move inside the adjusting cover 301, making the airbag 306 expand, so as to ensure that both airbags 306 are closely fitted to the adjacent tank.

[0052] When the oxygen distribution manifold body 1 fills the tank with gas, if there is a leakage, oxygen will leak into the first protective cover 202 and the second protective cover 203. When the alarm body 207 detects a relatively high oxygen concentration inside the oxygen distribution manifold body 1, it will send an alarm message. 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, causing the pushing block 502 to move closer to the first protective cover 202 inside the adjusting sleeve 501. When the pushing block 502 moves, it squeezes the telescopic rod 503 and the second spring 504, and can push the first connecting frame 507 and the second connecting frame 508 to move away from each other through the two pushing plates 506. The second connecting frame 508 pushes the closing block 601 to retract into the connecting cylinder 205.

8. A method for detecting and alarming of an oxygen distribution and manifold, applicable to an oxygen distribution and manifold detecting and alarming device according to any one of claims 1-7, characterized in that, It includes the following steps: S1. The operator adjusts the electric push rod (204). When the electric push rod (204) extends, 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 that needs to be filled with oxygen inside the first protective cover (202) and the second protective cover (203), and connects the air inlet of the tank to the connecting cylinder (205). Then the operator adjusts the electric push rod (204) to contract, so that the second protective cover (203) moves closer to the first protective cover (202) until they are tightly attached. When the second protective cover (203) moves closer to the first protective cover (202), the two threaded cylinders (402) on the same side of the first protective cover (202) and the second protective cover (203) are squeezed against each other, so that the sliding rod (303) pushes the activity plate (302) to move inside the adjusting cover (301), causing the airbag (306) to expand, so as to ensure that both airbags (306) are tightly attached to the adjacent tank. S2. When the oxygen distribution manifold body (1) inflates the tank body, if there is a leakage, oxygen will leak into the first protective cover (202) and the second protective cover (203). When the alarm body (207) detects a relatively high oxygen concentration inside the oxygen distribution manifold body (1), it will send an alarm message. 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 pushing block (502) moves closer to the first protective cover (202) inside the adjusting sleeve (501). When the pushing block (502) moves, it squeezes the telescopic rod (503) and the second spring (504), and can push the first connecting frame (507) and the second connecting frame (508) to move away from each other through the two pushing plates (506). The second connecting frame (508) pushes the closing block (601) to move into the connecting cylinder (205). Under the action of the guiding base (602), the closing block (601) automatically flips, and the oxygen gas flowing inside the connecting cylinder (205) can push the collecting cover (603), so that the rubber sleeve (604) fits against the inner wall of the connecting cylinder (205) to complete the blocking and closing process. The first connecting frame (507) pushes the alarm prompt board (509) to move away from the first protective cover (202), so as to further give an alarm and play a reminder role.
