Description

Technical Field

[0001] The invention relates to the technical field of technical protection, in particular to an emergency protection device for a pharmaceutical workshop. Background Art

[0002] Pharmaceutical workshops involve the production and processing of drugs, and have extremely strict requirements on the environment. The quality of drugs is directly related to people's life and health, so the safety, stability and reliability of the production process must be ensured. At the same time, various chemical substances, biological products and high-precision equipment are often used in the pharmaceutical process. In order to respond to sudden safety accidents and emergencies in the pharmaceutical process, protect personnel life safety, prevent environmental pollution, and ensure drug quality, emergency protection devices are needed.

[0003] In the prior art, when carrying out pharmaceutical operations in a workshop, it is necessary to use a gas pipe to participate in the pharmaceutical process. Compressed air or other gases are introduced into the conveying system through the gas pipe, so that the material is transported to the designated location along the pipeline under the action of the airflow. In some chemical reactions, specific gases are required to participate in the reaction to promote the reaction or control the rate and direction of the reaction. When the gas pipe is used for a long time, the pipeline will be subjected to repeated pressure changes, temperature changes and various external forces, which will cause tiny cracks in the pipeline and then leak. The leaked gas carries impurities, dust or other pollutants into the pharmaceutical production environment, contaminating the drugs being produced, thereby reducing the purity and quality of the drugs, making them fail to meet quality standards, resulting in the scrapping of drugs or adverse effects on the treatment effect of patients. Furthermore, leakage of the gas pipe will also lead to unstable gas pressure, thereby affecting key links such as reaction conditions and separation effects in the pharmaceutical process. For example, some chemical reactions require a specific gas pressure to ensure the progress of the reaction and the quality of the product. Unstable pressure will cause incomplete reactions or produce by-products, affecting the quality of the drugs.

[0004] Therefore, an emergency protection device for a pharmaceutical workshop is proposed to solve the above problems. Summary of the invention

[0015] Compared with the prior art, the present invention provides an emergency protection device for a pharmaceutical workshop, which has the following beneficial effects:

[0016] 1. Through the setting of the auxiliary detection and positioning mechanism, the driving body is started intermittently to make the auxiliary detection and positioning mechanism and the fixed-point sealing detection mechanism intermittently move on the conveying pipe, gradually check the conveying pipe for leakage, and let the detection structure gradually cover various parts of the conveying pipe to ensure that there is no omission. For long-distance conveying pipes, this comprehensive coverage is particularly important, which can greatly increase the probability of detecting leakage points. The mobile detection structure can reduce the direct contact between the staff and the conveying pipe, reduce the risk of personnel being injured by leaking gas during the detection process, and avoid the influence of human operating errors on the detection results, thereby improving the safety and reliability of the detection.

[0017] 2. Through the coordinated use of the outer shell and the inner shell, during the rotation of the auxiliary cavity, the outer shell gradually comes into contact with the delivery pipe, and the outer shell squeezes the gas in the inner shell and transmits it to the arc-shaped air pipe to blow and clean the surface of the delivery pipe to remove dust, dirt, impurities and other attachments, so as to avoid the attachments on the delivery pipe affecting the accuracy of leakage detection. The outer wall of the delivery pipe is smoother after cleaning, which reduces the friction between the mobile device and the delivery pipe, helps the mobile device to move more smoothly on the delivery pipe, reduces the risk of jamming and stagnation, and under the action of the material of the rubber sheet, further improves the friction between the delivery pipe, which helps to improve the stability and reliability of movement.

[0018] 3. Through the setting of the fixed-point sealing detection mechanism, when the first clamping body and the second clamping body are clamped together, they cooperate with the sealing strip and the outer wall of the conveying pipe to form a closed inner cavity, and then by detecting other changes, feedback is given on whether the conveying pipe is leaking. The first clamping body and the second clamping body are moved to a specific position of the conveying pipe for sealing, so that the possible leakage area can be quickly determined, and the detection range can be narrowed to a smaller interval, so as to quickly find the specific location of the leakage point. When a leak is detected, the clamping mechanism can keep the leakage position in a closed state, reduce the pressure and flow of the leaking gas, and take protective measures at the same time, effectively limiting the diffusion range of the leaking gas, preventing the leaking gas from further spreading to the entire workshop, reducing the harm to personnel and equipment, and making subsequent maintenance work easier.

An air pressure sensor 312 is fixedly connected to the inner wall of the first clamping body 34, and the air pressure sensor 312 is electrically connected to an external alarm device.

[0041] Everything in the above example works like this:

[0042] The following is the working process of the auxiliary detection positioning mechanism 2 for the leakage detection of the delivery pipe 1 by the auxiliary device moving the auxiliary fixed-point sealing detection mechanism 3 at various positions on the delivery pipe 1:

[0043] When in use, the multiple driving bodies 23 are all started by an external controller, and the output shaft of the driving body 23 drives the auxiliary cavity 24 to rotate in the forward direction. In the process of the driving body 23 driving the auxiliary cavity 24 to rotate, the rotation of the auxiliary cavity 24 drives the inner shell 29 of the outer ring of the auxiliary cavity 24 to gradually fit with the outer surface of the conveying pipe 1, so that the auxiliary cavity 24 rolls on the conveying pipe 1, driving the auxiliary detection and positioning mechanism 2 to change its position on the conveying pipe 1;

[0044] Furthermore, when the auxiliary cavity 24 rotates, the plurality of rubber sheets 210 intermittently roll on the delivery tube 1, and when the rubber sheet 210 fits against the delivery tube 1, under the effect of friction, the delivery tube 1 applies an effect to the rubber sheet 210, prompting the rubber sheet 210 to push the inner shell 29 to move into the outer shell 27. At this time, the movement of the inner shell 29 into the outer shell 27 pushes the auxiliary spring 212 to contract, and the air inlet 211 is synchronously received into the outer shell 27 under the effect of the movement of the inner shell 29. The inner wall of the outer shell 27 blocks the air inlet 211, and the inner shell 29 continues to move into the outer shell 27, so that the volume of the cavity formed by the outer shell 27 and the inner shell 29 is reduced, and the internal gas is compressed. Under the effect of the one-way air valve 28, the squeezed gas passes through the one-way air valve 28. The valve 28 flows into the auxiliary cavity 24. Since the auxiliary cavity 24 is connected with the arc-shaped air pipe 25, under this action, the air flow is blown out through the air outlet holes opened on the arc-shaped air pipe 25 to clean the surface of the delivery pipe 1, so as to prevent the presence of impurities from affecting the movement of the auxiliary detection and positioning mechanism 2. Under the continuous rotation of the auxiliary cavity 24, the next rubber sheet 210 gradually conflicts with the delivery pipe 1, and the previous rubber sheet 210 gradually separates from the rubber sheet 210. After separation, the restoring force of the auxiliary spring 212 pushes the inner shell 29 to move away from the outer shell 27, and the air inlet 211 also gradually moves away from the outer shell 27. The external air is gradually replenished into the cavity formed by the outer shell 27 and the inner shell 29 through the air inlet 211, waiting for the subsequent extrusion operation.

[0045] By setting up the auxiliary detection and positioning mechanism 2, the driving body 23 is started intermittently so that the auxiliary detection and positioning mechanism 2 and the fixed-point sealing detection mechanism 3 are intermittently moved on the conveying pipe 1, and the conveying pipe 1 is gradually checked for leakage, so that the detection structure gradually covers various parts of the conveying pipe 1 to ensure that there are no omissions. For long-distance conveying pipes 1, this comprehensive coverage is particularly important, which can greatly increase the probability of detecting leakage points, and the mobile detection structure can reduce the direct contact between the staff and the conveying pipe 1, reduce the risk of personnel being injured by leaking gas during the detection process, and can also avoid the influence of human operational errors on the detection results, thereby improving the safety and reliability of the detection.

[0046] Through the coordinated use of the outer shell 27 and the inner shell 29, during the rotation of the auxiliary cavity 24, the outer shell 27 gradually comes into contact with the delivery pipe 1, and the outer shell 27 squeezes the gas in the inner shell 29 and transmits it to the arc-shaped air pipe 25 to blow and clean the surface of the delivery pipe 1 to remove dust, dirt, impurities and other attachments, so as to prevent the attachments on the delivery pipe 1 from affecting the accuracy of leakage detection. The outer wall of the delivery pipe 1 after cleaning is smoother, which reduces the friction between the moving device and the delivery pipe 1, helps the moving device to move more smoothly on the delivery pipe 1, reduces the risk of jamming and stagnation, and under the action of the material of the rubber sheet 210, the friction between the delivery pipe 1 is further improved, which helps to improve the stability and reliability of movement.

[0047] Please refer to the above working process Figures 1 to 5 .

[0048] The following is the working process of the fixed-point sealing detection mechanism 3 which moves on the delivery pipe 1 following the motion trajectory of the auxiliary detection positioning mechanism 2 and then performs leakage detection on the delivery pipe 1 and performs emergency sealing treatment when leaks are detected:

[0049] During use, the driver 23 drives the auxiliary cavity 24 to rotate, thereby driving the auxiliary detection and positioning mechanism 2 to move as a whole on the conveying pipe 1. The two sets of auxiliary detection and positioning mechanisms 2 are set, and with the assistance of the arc plate 31, the first clamping body 34 and the second clamping body 35 are indirectly connected to the arc-shaped electric-controlled clamping claw 21, so that the fixed-point sealing detection mechanism 3 is driven to move on the conveying pipe 1 through the auxiliary detection and positioning mechanism 2. During the detection, if the driver 23 is set to stop driving for ten seconds, then The fixed-point sealing detection mechanism 3 is in a stationary state on the conveying pipe 1 for ten seconds. At this time, the electromagnetic column 310 is energized to generate magnetism. Under the action of magnetic attraction, the electromagnetic column 310 is adsorbed with the magnetic column 311, and the traction spring 39 is stretched. The electromagnetic column 310 slides into the clamping hole 38 on the second clamping body 35 and is adsorbed with the magnetic column 311. Under the action of the magnetic attraction of the electromagnetic column 310 and the magnetic column 311, the first clamping body 34 and the second clamping body 35 are pulled closer to each other until they fit together. At this time, the first clamping body 3 4 and the second clamping body 35 form a round tube. Since the arc plate 31 is fixedly connected to the arc-shaped electric-controlled clamping claw 21, the first clamping body 34 and the second clamping body 35 are closed. The first clamping body 34 and the second clamping body 35 move away from the arc plate 31, causing the reset spring 33 to be stretched. Then, with the assistance of the sealing strip 36, the first clamping body 34, the second clamping body 35 and the sealing strip 36 form a closed state with the surface of the conveying pipe 1. If a leak occurs at the position of the conveying pipe 1 at this time, the first clamping body 34 The air pressure in the closed cavity formed by the second clamping body 35, the sealing strip 36 and the conveying pipe 1 rises. After accumulating for ten seconds, the air pressure intensity rises to the trigger value of the air pressure sensor 312. The air pressure sensor 312 detects the air pressure change, so that the external alarm device connected to the air pressure sensor 312 is activated, prompting the operator that the conveying pipe 1 leaks and needs emergency treatment. Before the operator handles it, the electromagnetic column 310 is in the energized state and has magnetism, which assists the closing of the first clamping body 34 and the second clamping body 35;

[0050] If there is no leakage in the delivery pipe 1 here, after ten seconds, the air pressure does not change, the electromagnetic column 310 is powered off, the magnetism disappears, and under the restoring force of the traction spring 39, the electromagnetic column 310 is pulled apart from the magnetic column 311. At this time, the first clamping body 34 and the second clamping body 35 are in contact in the closed state. Further, under the restoring force of the reset spring 33, the first clamping body 34 and the second clamping body 35 are pulled to move toward the arc plate 31 respectively. Under the start of the driving body 23, the auxiliary detection positioning mechanism 2 and the fixed-point sealing detection mechanism 3 are continuously pushed to move on the delivery pipe 1, and the above steps are repeated to perform the detection operation, so as to perform emergency protection treatment for the leakage of the delivery pipe 1;

[0051] By setting the fixed-point sealing detection mechanism 3, under the clamping connection of the first clamping body 34 and the second clamping body 35, they cooperate with the sealing strip 36 and the outer wall of the conveying pipe 1 to form a closed inner cavity, and then feedback whether the conveying pipe 1 is leaking is fed back by detecting other changes. The first clamping body 34 and the second clamping body 35 are moved to a specific position of the conveying pipe 1 for sealing, and the possible leakage area can be quickly determined, and the detection range can be narrowed to a smaller interval, so as to quickly find the specific location of the leakage point, and when the leakage is detected, the clamping mechanism can keep the leakage position in a closed state, reduce the pressure and flow of the leaking gas, and take protective measures at the same time, effectively limit the diffusion range of the leaking gas, prevent the leaking gas from further spreading to the entire workshop, reduce the harm to personnel and equipment, and make subsequent maintenance work easier.
