Description

Technical Field

[0001] The present invention relates to the technical field of trachea detection, and particularly relates to a compressor trachea seal detection device and a detection process. Background Art

[0002] Compressors are usually used for high-pressure and high-speed gas compression and transmission. If the trachea seal is poor, gas leakage may occur. This not only causes energy waste but may also trigger safety accidents such as explosions and fires. Therefore, seal detection of the trachea after production is a necessary measure to ensure the safe operation of the compressor.

[0003] Currently, there are usually two ways to detect the seal of the compressor trachea. The first is the soap bubble method and the water immersion method. A certain pressure of leak detection gas (usually air or nitrogen) is filled into the trachea, and soap solution is applied to the trachea or the trachea is placed in water to observe whether bubbles are formed. If bubbles are formed, it indicates leakage. The second is the pressure detection method. Similarly, a certain amount of gas is filled into the trachea, and at the same time, a pressure sensor is used to detect the pressure change in the trachea. If the pressure decreases, it indicates leakage.

[0004] However, in the actual application process, both of these methods have certain drawbacks. For the first one: existing compressor tracheas are usually mass-produced, so the number of tracheas to be detected is large. When using the soap bubble method and the water immersion method for detection, whether there is leakage or not, the tracheas after detection need to be cleaned and dried, which is rather cumbersome. For the second one: although the pressure detection method does not require processing of the tracheas after detection, during the detection process, if there is leakage in the trachea but the leakage point cannot be effectively located, the first method still needs to be used to further locate the leakage point. Summary of the Invention

[0005] The purpose of the present invention is to provide a compressor trachea seal detection device and a detection process to solve the following technical problems:

[0006] 1) When using the soap bubble method and the water immersion method for detection, the tracheas after detection need to be cleaned and dried; 2) When using the pressure detection method for detection, the leakage point cannot be accurately located.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A compressor trachea seal detection device includes a detection table, on which a detection box is fixedly arranged. The detection box is provided with a first gas transmission module for inputting oxygen into the detection box.

[0009] On one side of the detection box, a positioning module for positioning the trachea body is also arranged. There is a feeding port on the side of the detection box close to the positioning module, and a feeding module is also arranged on the detection table for inputting the positioned trachea body into the detection box.

[0010] Among them, a second gas transmission module is also arranged in the detection box, and the second gas transmission module is used to input nitric oxide into the trachea body.

[0011] Preferably, the positioning module includes a first positioning plate and a second positioning plate arranged on the detection table. Semi-circular grooves are opened on the sides of the first positioning plate and the second positioning plate close to each other.

[0012] Among them, an adjustment module is arranged on the detection table, and the adjustment module is used to drive the first positioning plate and the second positioning plate to approach or move away from each other.

The other ends of the lifting rods are rotatably connected to the adjusting seats.

[0015] Preferably, sliding grooves for embedding the first positioning rod and the second positioning rod are respectively opened on both sides of the bottom of the detection box.

[0016] A sealing plate is slidably embedded at the feeding port. The sealing plate is connected to a first elastic part arranged in the detection box. Sealing strips are slidably embedded in the two sliding grooves. The sealing strips are connected to a second elastic part arranged outside the detection box.

[0017] Preferably, a sealing box is fixedly arranged on the side of the second positioning plate away from the detection box.

[0018] Among them, sealing rods are respectively fixedly arranged at the ends of the first positioning rod and the second positioning rod away from the detection box, and the sealing rods extend in the direction away from the detection box.

[0019] Preferably, support cylinders are respectively fixedly arranged on both sides in the detection box. Positioning ends are slidably embedded in the support cylinders. The outer peripheral surfaces of the two positioning ends close to each other are arranged as conical inclined surfaces.

[0020] Among them, limiting rods are fixedly arranged on the sides of the two support cylinders away from each other. A limiting plate fixedly connected to the positioning end is slidably sleeved on the limiting rod, and a third spring is arranged on the limiting rod.

[0021] Preferably, the second gas transmission module includes a second air pump fixed to the outside of the detection box. The second air pump is connected to the nitric oxide storage tank. The other end of the second air pump is connected to a fourth air pipe. The fourth air pipe passes through the side wall of the detection box and is connected to one of the positioning ends.

[0022] Wherein, an air transmission channel communicating with the fourth air pipe is provided at the center of the axis of the positioning end on this side, and the positioning end on the other side is fixed to a guide shaft slidably arranged on the detection box.

[0023] Preferably, baffles are slidably arranged on both sides of the sealing box. The two baffles extend into the feeding port. Struts are fixedly arranged in the sealing box. Sliding seats are slidably arranged on the struts. Guide grooves are respectively provided on both sides of the sealing box. The sliding seats are fixed to the baffles through connecting rods passing through the guide grooves.

[0024] Wherein, a fourth spring is provided on the strut.

[0025] Preferably, partitions are arranged on one side of the two support cylinders close to each other. The partitions are slidably fitted with the support cylinders. A sleeve is fixedly arranged in the detection box. One side of the sleeve close to the support cylinder is slidably inserted with a telescopic rod. The other end of the telescopic rod is fixed to the partition.

[0026] Wherein, a fifth spring fixedly connected to the telescopic rod is also fixedly arranged in the sleeve.

[0027] A compressor air pipe sealing detection process, which is applied to the above-mentioned compressor air pipe sealing detection device, includes the following steps:

[0028] The adjustment module drives the first positioning plate and the second positioning plate to separate from each other, and places the air pipe body between the first positioning plate and the second positioning plate.

[0029] After placement, the adjustment module drives the first positioning plate and the second positioning plate to approach each other, and positions the air pipe body in the circular groove.

[0030] The feeding module inputs the positioned air pipe body into the detection box along the feeding port.

[0031] The first gas transmission module inputs oxygen into the detection box. The second gas transmission module inputs a certain amount of nitric oxide gas into the air pipe body and keeps both ends of the air pipe body sealed.

[0032] If there is a leak in the air pipe body, the nitric oxide gas is discharged along the leak point and contacts the oxygen, and then reddish-brown nitrogen dioxide gas is generated. The detection personnel can locate the leak point.

[0033] After the detection is completed, the feeding module can discharge the air pipe body.

[0034] The beneficial effects of the present invention:

[0035] After the located trachea body is transported to the detection box, first, oxygen is input into the detection box through the first air delivery module. Secondly, a certain amount of nitric oxide gas is input into the trachea body through the second air delivery module, and both ends of the trachea body are kept sealed. If there is a leak in the trachea body, the nitric oxide gas can be discharged along the leak point and come into contact with oxygen, and then brownish-red nitrogen dioxide gas is generated. The detector can then locate the leak point. Correspondingly, multiple monitors can be set in the detection box to monitor the trachea body. If no brownish-red gas is generated during the detection process, it indicates that the trachea body is not leaking. Through the detection method of the present invention, not only can the leak point be located, but also during the detection process, no detection liquid will adhere to the trachea body, so there is no need for subsequent cleaning and drying processes, effectively improving the detection accuracy and efficiency, and facilitating the batch production of compressor tracheas;

[0036] When the present invention is feeding, as the first positioning plate and the second positioning plate push the sealing plate to contract into the detection box, the sealing box also synchronously embeds into the feeding port. The outer edge surface of the sealing box slides and fits with the side wall of the feeding port, thereby achieving the effect of closing the feeding port, and the gas in the detection box will not be discharged; Correspondingly, when the first positioning rod and the second positioning rod push the sealing strip to slide along the chute, the sealing rod also synchronously embeds into the chute to seal the chute to ensure the airtightness of the detection box. After the first air delivery module inputs oxygen into the detection box, it can be reused, avoiding the phenomenon of oxygen leakage, reducing costs, and at the same time, it can also avoid air pollution caused by the discharge of nitrogen dioxide;

[0037] In the initial state of the present invention, the partition plate is in a state of sealing the support cylinder, and the oxygen in the detection box will not enter the support cylinder. As the trachea body moves into the detection box and pushes the sealing plate to move, the sealing plate can synchronously push the partition plate to shift to one side of the support cylinder until the trachea body communicates with the support cylinder. During this process, oxygen will not enter the support cylinder, further ensuring the detection accuracy of the subsequent airtightness of the trachea body;

[0038] In the initial state of the present invention, the conical inclined surface at the end of the positioning end protrudes outside the support cylinder. As the feeding module drives the trachea body to move into the detection box, the two side edges of the first positioning plate first abut against the conical inclined surface to compress the positioning end into the support cylinder. At this time, the third spring deforms and generates elastic force. When the trachea body moves to a position corresponding to the support cylinder, based on the elastic force of the third spring, it can drive the positioning end to embed into the pipe orifice of the trachea body. At this time, the conical inclined surface abuts against the pipe orifice, thereby realizing the repositioning of the trachea body. Even if the first positioning plate and the second positioning plate are separated from each other subsequently, the trachea body will not fall. When the first positioning plate and the second positioning plate approach each other, the trachea body can be embedded into the circular groove for discharging materials.

Specific embodiments

[0056] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0057] Embodiment 1

[0058] Please refer to Figure 1 - Figure 2 As shown, the present invention is a compressor trachea sealing detection device, including a detection table 1, a detection box 2 is fixedly arranged on the detection table 1, and a first gas transmission module is arranged on the detection box 2, and the first gas transmission module is used to input oxygen into the detection box 2;

[0059] On one side of the detection box 2, there is also a positioning module 5 for positioning the trachea body 8. Among them, on the side of the detection box 2 facing the positioning module 5, there is a feeding port 201, and on the detection table 1, there is also a feeding module 101 for inputting the positioned trachea body 8 into the detection box 2. Specifically, when detecting the trachea body 8 of the compressor in this embodiment, first, the trachea body 8 is positioned and fixed by the positioning module 5 outside the detection box 2. After positioning, the positioned trachea body 8 can be input into the detection box 2 through the feeding module 101 for subsequent detection.

[0060] In this embodiment, a second gas transmission module is also arranged in the detection box 2, and the second gas transmission module is used to input nitric oxide into the trachea body 8.

[0061] It should be noted that when these two colorless gases, nitric oxide and oxygen, come into contact, a color change will occur. Specifically, after nitric oxide reacts with oxygen, red-brown nitrogen dioxide gas can be rapidly generated. This chemical reaction can be expressed as: ;

[0062] Therefore, in this embodiment, after the positioned trachea body 8 is transported to the detection box 2, first, oxygen is input into the detection box 2 through the first gas transmission module. Secondly, a certain amount of nitric oxide gas is input into the trachea body 8 through the second gas transmission module, and both ends of the trachea body 8 are kept sealed. If there is a leak in the trachea body 8, the nitric oxide gas can be discharged along the leak point and come into contact with oxygen, and then red-brown nitrogen dioxide gas is generated. The detection personnel can then locate the leak point. Correspondingly, multiple monitors 801 can be arranged in the detection box 2 in this embodiment to monitor the trachea body 8 (reference can be made to Figure 12 ). If no red-brown gas is generated during the detection process, it indicates that the trachea body 8 is not leaking. Through the detection method of this embodiment, not only can the leak point be located, but also during the detection process, no detection liquid will adhere to the trachea body 8. Therefore, there is no need for subsequent cleaning and drying treatment, effectively improving the detection accuracy and efficiency, and facilitating the batch production of the compressor trachea.

[0063] In addition, when the first gas transmission module inputs oxygen into the detection box 2 and the second gas transmission module inputs nitric oxide into the trachea body 8 in this embodiment, the pressure in the trachea body 8 needs to be greater than the pressure in the detection box 2 to prevent the oxygen in the detection box 2 from flowing back into the trachea body 8 along the leak point. At the same time, due to the relatively high pressure in the trachea body 8, if there is a leak point, nitric oxide can be quickly discharged and combined with oxygen, and the detection rate is higher. Specifically, the pressure value can be detected by setting pressure sensors at the gas transmission ends of the first gas transmission module and the second gas transmission module. This detection means is an existing technology, and the specific structure of this embodiment is not limited.

[0064] Embodiment 2

[0065] Based on Embodiment 1, please refer to Figure 3 - Figure 5 , the positioning module 5 includes a first positioning plate 501 and a second positioning plate 502 disposed on the detection table 1. The upper and lower surfaces of the first positioning plate 501 and the second positioning plate 502 are flush with each other. Semi-circular grooves 513 are formed on the sides of the first positioning plate 501 and the second positioning plate 502 that are close to each other. When the first positioning plate 501 and the second positioning plate 502 are attached, the two sets of semi-circular grooves 513 enclose a circular groove for positioning the trachea body 8; wherein, an adjustment module is provided on the detection table 1, and the adjustment module is used to drive the first positioning plate 501 and the second positioning plate 502 to approach or move away from each other; it can be explained that before detecting the trachea body 8, the first positioning plate 501 and the second positioning plate 502 are located outside the detection box 2. In this embodiment, the adjustment module can be used to drive the first positioning plate 501 and the second positioning plate 502 to separate from each other, so as to facilitate placing the trachea body 8 between the first positioning plate 501 and the second positioning plate 502. After placing, the adjustment module can be used to drive the first positioning plate 501 and the second positioning plate 502 to approach each other to position the trachea body 8 in the circular groove (please refer to Figure 13 ), and then the positioned trachea body 8 can be input into the detection box 2 along the feed port 201 through the feeding module 101 (please refer to Figure 14 ). After the first air supply module and the second air supply module complete the air supply, the adjustment module drives the first positioning plate 501 and the second positioning plate 502 to move away from each other again, so that the trachea body 8 can be completely exposed in the detection box 2 (please refer to Figure 15 ), so as to facilitate monitoring of the leakage point; after the detection is completed, the adjustment module drives the first positioning plate 501 and the second positioning plate 502 to approach each other again to position the trachea body 8, and finally the trachea body 8 can be drawn out along the feed port 201 through the feeding module 101.

[0066] In addition, the feeding module 101 of this embodiment can adopt a screw-nut transmission mechanism or a synchronous belt transmission mechanism, and this embodiment does not limit this, as long as it can satisfy the actual driving of the positioning module 5 to reciprocate linearly on the detection table 1.

[0067] In this embodiment, please refer to Figure 3 - Figure 4, on one side of the bottom of the first positioning plate 501, a first positioning rod 506 is vertically and fixedly arranged. On the other side of the bottom of the second positioning plate 502, a second positioning rod 504 is vertically and fixedly arranged. On the sides of the first positioning rod 506 and the second positioning rod 504 close to each other, adjusting rods 507 are vertically and fixedly arranged respectively. The ends of the adjusting rods 507 are fixed to the adjusting seats 508. The two adjusting seats 508 are respectively slidably sleeved on the support rods 509. Among them, the adjusting module includes a lifting cylinder 102 fixedly arranged on the driving end of the feeding module 101. Outside the lifting cylinder 102, a U-shaped frame 510 fixed to the support rod 509 is fixedly arranged. The telescopic end of the lifting cylinder 102 is fixed to the lifting seat 511. On both sides of the lifting seat 511, lifting rods 512 are rotatably arranged. The other ends of the lifting rods 512 are rotatably connected to the adjusting seats 508. It can be explained that when feeding the trachea body 8 into the detection box 2 after driving and positioning in this embodiment, the feeding module 101 can be driven to move the lifting cylinder 102. The lifting cylinder 102 drives the first positioning plate 501 and the second positioning plate 502 to move synchronously through the U-shaped frame 510, the support rod 509, the lifting rod 512, the adjusting rod 507, and the first positioning rod 506 and the second positioning rod 504. Correspondingly, when the distance between the first positioning plate 501 and the second positioning plate 502 needs to be adjusted, the lifting cylinder 102 can be driven to lift the lifting seat 511. The lifting seat 511 can drive the adjusting seat 508 to slide on the support rod 509 through the lifting rod 512. The adjusting seat 508 can drive the first positioning plate 501 and the second positioning plate 502 to approach or move away from each other synchronously through the adjusting rod 507.

[0068] Correspondingly, in this embodiment, when the feeding module 101 drives the first positioning plate 501 and the second positioning plate 502 to move along the feeding port 201, in order to avoid interference between the first positioning rod 506 and the second positioning rod 504 and the bottom of the detection box 2, reference can be made to Figure 6 , on both sides of the bottom of the detection box 2, sliding grooves 208 for embedding the first positioning rod 506 and the second positioning rod 504 are respectively opened; specifically, when the first positioning plate 501 and the second positioning plate 502 move along the feeding port 201, the first positioning rod 506 and the second positioning rod 504 can move synchronously along the sliding grooves 208.

[0069] As a further solution of this embodiment, in order to prevent oxygen or nitrogen dioxide from being discharged along the feeding port 201 or the sliding groove 208, reference can be made to Figure 6, a sealing plate 202 is slidably embedded at the feed inlet 201, and the sealing plate 202 is connected to the first elastic part disposed in the detection box 2. Sealing strips 204 are slidably embedded in the two side chutes 208, and the sealing strips 204 are connected to the second elastic part disposed outside the detection box 2. It can be noted that in the initial state, based on the settings of the first elastic part and the second elastic part, the sealing plate 202 is in a state of sealing the feed inlet 201, and the sealing strips 204 are in a state of sealing the chutes 208. When the trachea body 8 feeds materials into the detection box 2, as the positioning plate and the positioning rod move, the sealing plate 202 and the sealing strips 204 can be squeezed to slide in a direction away from the positioning module 5. The sealing plate 202 squeezes the first elastic part and generates an elastic force, and the sealing strips 204 squeeze the second elastic part and generate an elastic force. When the positioning module 5 resets, the elastic part can be used to drive the sealing plate 202 and the sealing strips 204 to reset.

[0070] For reference Figure 7 , the first elastic part includes a first guide rod 210 fixed in the detection box 2. An L-shaped support plate 209 is fixedly arranged on one side of the sealing plate 202. The L-shaped support plate 209 is slidably sleeved on the first guide rod 210. A first spring 211 is arranged on the first guide rod 210. One end of the first spring 211 is fixed to the L-shaped support plate 209, and the other end is fixed to the end of the first guide rod 210. It can be noted that as the sealing plate 202 moves, the first spring 211 can be squeezed by the L-shaped support plate 209 to generate an elastic force.

[0071] For reference Figure 2 , the second elastic part includes a through groove 203 formed in the detection box 2 and corresponding to the position of the chute 208. The sealing strip 204 passes through the through groove 203 and is fixed to a guide plate 205. A second guide rod 206 is fixedly arranged outside the detection box 2. The guide plate 205 is slidably sleeved on the second guide rod 206. A second spring 207 is arranged on the second guide rod 206. One end of the second spring 207 is fixed to the guide plate 205, and the other end is fixed to the end of the second guide rod 206. It can be noted that as the sealing strip 204 moves, the second spring 207 can be squeezed by the guide plate 205 to generate an elastic force.

[0072] In addition, in this embodiment, after the first positioning plate 501 and the second positioning plate 502 are combined, a complete cuboid structure can be formed, so that when passing through the feed inlet 201, the outer edge surfaces of the first positioning plate 501 and the second positioning plate 502 are slidably attached to the side wall of the feed inlet 201, and the gas in the detection box 2 will not be discharged from the gap between the positioning plate and the feed inlet 201. Correspondingly, when the sealing strip 204 slides along the chute 208, the outer edge surface of the sealing strip 204 can be slidably attached to the groove wall of the chute 208, and the fixed gas in the detection box 2 will not be discharged from the gap between the sealing strip 204 and the chute 208;

[0073] As a further solution of this embodiment, reference can be made to Figure 4 - Figure 6 On the side of the second positioning plate 502 away from the detection box 2, a sealing box 505 is fixedly arranged. Among them, sealing rods 503 are fixedly arranged at the ends of the first positioning rod 506 and the second positioning rod 504 away from the detection box 2 respectively. The sealing rods 503 extend in a direction away from the detection box 2, and the width of the sealing rods 503 is equal to the width of the sealing strip 204. It can be explained that during feeding, as the first positioning plate 501 and the second positioning plate 502 push the sealing plate 202 to contract into the detection box 2, the sealing box 505 is also synchronously embedded into the feed port 201. The outer peripheral surface of the sealing box 505 slides and fits with the side wall of the feed port 201, thereby achieving the effect of closing the feed port 201, and the gas in the detection box 2 will not be discharged. Correspondingly, when the first positioning rod 506 and the second positioning rod 504 push the sealing strip 204 to slide along the chute 208, the sealing rods 503 are also synchronously embedded into the chute 208 to seal the chute 208 to ensure the airtightness of the detection box 2.

[0074] Therefore, during the feeding and discharging processes of the trachea body 8 in this embodiment, the airtightness of the detection box 2 can be always maintained. After the first gas supply module inputs oxygen into the detection box 2, it can be reused, avoiding the phenomenon of oxygen leakage, reducing costs, and at the same time, it can also avoid air pollution caused by the discharge of nitrogen dioxide.

[0075] Reference can be made to Figure 1 - Figure 2 and Figure 12 The first gas supply module includes a first air pump 3 fixed on the detection box 2. An exhaust box 307 is fixedly arranged in the detection box 2. A plurality of groups of exhaust holes 308 are arranged at the bottom of the exhaust box 307. The exhaust box 307 is connected to the first air pump 3 through a first air pipe 306. One end of the first air pump 3 away from the first air pipe 306 is connected to a three-way valve 301. One end of the three-way valve 301 is connected to a recovery tank 305 through a second air pipe 303, and the other end of the three-way valve 301 is connected to an oxygen storage tank 304 through a third air pipe 302. It can be explained that when inputting oxygen into the detection box 2 in this embodiment, first, the three-way valve 301 is switched to connect the third air pipe 302 with the first air pump 3. The first air pump 3 can transport the oxygen in the oxygen storage tank 304 to the exhaust box 307 through the third air pipe 302, and finally discharge it into the detection box 2 through the exhaust holes 308. Correspondingly, when the trachea body 8 leaks air, in this embodiment, the three-way valve 301 can be switched to connect the second air pipe 303 with the recovery tank 305. The first air pump 3 pumps the nitrogen dioxide and the remaining oxygen in the detection box 2 into the recovery tank 305 for recovery to avoid interfering with subsequent detections, and then pure oxygen can be input again.

[0076] Further, after the trachea body 8 enters the detection box 2, as the first positioning plate 501 and the second positioning plate 502 separate from each other, to prevent the trachea body 8 from falling after losing its positioning function, in this embodiment, reference can be made to Figure 7 - Figure 11 , support cylinders 703 are fixedly arranged on both sides in the detection box 2. Positioning ends 704 are slidably embedded in the support cylinders 703. The outer peripheral surfaces of the two positioning ends 704 on the side close to each other are provided with conical inclined surfaces 709. Among them, limiting rods 705 are fixedly arranged on the sides of the two support cylinders 703 away from each other. A limiting plate 707 fixedly connected to the positioning end 704 is slidably sleeved on the limiting rod 705. A third spring 706 is arranged on the limiting rod 705. One end of the third spring 706 is fixed to the support cylinder 703, and the other end is fixed to the limiting plate 707. It can be explained that in the initial state, the conical inclined surface 709 at the end of the positioning end 704 protrudes outside the support cylinder 703. As the feeding module 101 drives the trachea body 8 to move into the detection box 2, the two side edges of the first positioning plate 501 first abut against the conical inclined surface 709 and compress the positioning end 704 into the support cylinder 703. At this time, the third spring 706 deforms and generates an elastic force. When the trachea body 8 moves to a position corresponding to the support cylinder 703, based on the elastic force of the third spring 706, the positioning end 704 can be driven to embed into the tube orifice of the trachea body 8. At this time, the conical inclined surface 709 abuts against the tube orifice (reference can be made to Figure 11 ), thereby realizing re-positioning of the trachea body 8. Even if the first positioning plate 501 and the second positioning plate 502 separate from each other subsequently, the trachea body 8 will not fall. When the first positioning plate 501 and the second positioning plate 502 approach each other, the trachea body 8 can be embedded into the circular groove again to facilitate discharging.

[0077] Reference can be made to Figure 1 - Figure 2 and Figure 8 , the second gas transmission module includes a second air pump 4 fixed outside the detection box 2. The second air pump 4 is connected to a nitric oxide storage tank 402. The other end of the second air pump 4 is connected to a fourth air pipe 401. The fourth air pipe 401 passes through the side wall of the detection box 2 and is connected to one of the positioning ends 704. Among them, an air transmission channel communicating with the fourth air pipe 401 is opened at the axis of this positioning end 704. The other positioning end 704 is fixed to a guide shaft 403 slidably arranged on the detection box 2. It can be explained that after the two positioning ends 704 position the trachea body 8, the second air pump 4 can be started. The second air pump 4 extracts nitric oxide from the nitric oxide storage tank 402 and transports it to the positioning end 704 through the fourth air pipe 401, and finally transports it into the trachea body 8 through the air transmission channel;

[0078] In addition, a telescopic pipe is also arranged in the fourth air pipe 401, so that the positioning end 704 connected to it can slide in the support cylinder 703.

[0079] In this embodiment, reference can be made to Figure 3 - Figure 5 and Figure 7 - Figure 11 . During the process of the trachea body 8 entering the detection box 2, in order to prevent oxygen in the detection box 2 from entering the tube, baffles 6 are slidably arranged on both sides of the sealing box 505, and the two baffles 6 extend into the feeding port 201 (reference can be made to Figure 1 ). Pillars 602 are fixedly arranged in the sealing box 505, and sliders 603 are slidably arranged on the pillars 602. Guide grooves 601 are respectively opened on both sides of the sealing box 505. The sliders 603 are fixed to the baffles 6 through connecting rods penetrating the guide grooves 601. Among them, a fourth spring 604 is arranged on the pillar 602. One end of the fourth spring 604 is fixed to the box wall of the sealing box 505, and the other end is fixed to the slider 603. It can be explained that in the initial state, the two baffles 6 can seal the two pipe orifices of the trachea body 8, and as the trachea body 8 moves into the detection box 2, oxygen can be prevented from entering the tube. Reference can be made to Figure 14 . When the trachea body 8 continues to move, the two baffles 6 stop moving under the abutting action of the support cylinder 703 until the trachea body 8 moves to communicate with the support cylinder 703.

[0080] It should also be noted that before the trachea body 8 is connected to the support cylinder 703, oxygen in the detection box 2 will enter the support cylinder 703. When the trachea body 8 is connected to the support cylinder 703, oxygen will still enter the trachea body 8, thus causing detection errors. Correspondingly, in this embodiment, reference can be made to Figure 7 - Figure 9 . Partition plates 7 are arranged on the sides of the two support cylinders 703 close to each other. The partition plates 7 are slidably fitted with the support cylinders 703. Sleeves 702 are fixedly arranged in the detection box 2. One side of the sleeve 702 close to the support cylinder 703 is slidably inserted with a telescopic rod 701, and the other end of the telescopic rod 701 is fixed to the partition plate 7. Among them, a fifth spring 708 fixedly connected to the telescopic rod 701 is also fixedly arranged in the sleeve 702. It can be explained that in the initial state, the partition plate 7 is in a state of sealing the support cylinder 703, and oxygen in the detection box 2 will not enter the support cylinder 703. As the trachea body 8 moves into the detection box 2 and pushes the sealing plate 202 to move, the sealing plate 202 can synchronously push the partition plate 7 to shift to one side of the support cylinder 703 (reference can be made to Figure 14 ) until the trachea body 8 communicates with the support cylinder 703. During this process, oxygen will not enter the support cylinder 703, further ensuring the detection accuracy of the subsequent sealing performance of the trachea body 8.

[0081] A detection process of a compressor trachea sealing detection device includes the following steps:

[0082] Please refer to Figure 3 - Figure 5 . S1. The adjustment module drives the first positioning plate 501 and the second positioning plate 502 to separate from each other, and places the trachea body 8 between the first positioning plate 501 and the second positioning plate 502;

[0083] S2. After placement, the module is adjusted to drive the first positioning plate 501 and the second positioning plate 502 to approach each other, and the trachea body 8 is positioned in the circular groove.

[0084] Please refer to Figure 1 - Figure 3 , S3. The feeding module 101 inputs the positioned trachea body 8 into the detection box 2 along the feeding port 201.

[0085] S4. The first gas transmission module inputs oxygen into the detection box 2, and the second gas transmission module inputs a certain amount of nitric oxide gas into the trachea body 8 and keeps both ends of the trachea body 8 sealed.

[0086] S5. If the trachea body 8 leaks, the nitric oxide gas is discharged along the leakage point and contacts the oxygen, and then brown nitrogen dioxide gas is generated. The detection personnel can locate the leakage point.

[0087] S6. After the detection is completed, the feeding module 101 discharges the trachea body 8.
