When the scheme is put into practical use, firstly, the pipeline to be detected is fed through the feeding group, after the feeding is completed, the two ends of the pipeline are positioned between the two opposite sealing plates 17, the pipeline can be buffered to a certain extent when being clamped by the sealing plates 17 and the third springs 18, the motor 3 and the air pump 5 are required to be started when the pipeline is started to detect, the air pump 5 discharges the outside air into the support frame 4, because the support frame 4 is hollow, the air enters the support frame 4 and then enters the interior of the pipeline through the air holes formed in the connecting shell 6 and the sealing plates 17, the motor 3 is supported through the support plate 2, the support frame 4 and the air pump 5 are driven to rotate when the motor 3 rotates, the water tank 1 is filled with water, a worker only needs to observe the pipeline below the first air cylinder 15, after the support frame 4 drives the pipeline to be detected to be submerged in the water, if the pipeline has cracks, bubbles are generated, which indicates that the air tightness of the pipeline is defective, along with the rotation of the motor 3, when the pipeline is out of water and rotates to one side of the push plate 16, a worker starts the first air cylinder 15, the first air cylinder 15 is supported by the first L-shaped rod 14, the push plate 16 is driven by the first air cylinder 15 to contact with the contact plate 8 at one side of the defective pipeline, the two contact plates 8 are pushed by the two push plates 16 to move towards the two motors 3 respectively, the two contact plates 8 are driven to move to drive the two connecting shells 6 to move, the sealing plate 17 is driven to move when the two connecting shells 6 move, at the moment, the third spring 18 is slowly relaxed, after the third spring 18 is completely relaxed, the push plate 16 continues to push the rear end of the contact plate 8 to slide into the supporting frame 4 each time, and the first spring 7 is compressed, after the first spring 7 is compressed to the limit position, the two sealing plates 17 are not contacted with the pipeline, at the moment, the defective pipeline can directly fall onto the baffle plate 12, then the first air cylinder 15 is reset, the sealing plates 17 and the connecting shell 6 are reset successively under the elastic action of the first spring 7 and the third spring 18, the baffle plate 12 and the material receiving plate 10 are obliquely arranged, and the defective pipeline falling onto the material receiving plate 10 can directly roll to one side, so that the air tightness detection and the blanking work are completed;
after the first air cylinder 15 is started, the defective pipelines automatically fall through the pushing piece 16 and the contact plate 8, at the moment, a worker only needs to observe whether the next pipeline can generate bubbles in water or not, if the air tightness of all the pipelines is free of problems, the first air cylinder 15 is not required to be started, after the detected pipelines rotate for a circle, the defective pipelines can be fed one by one through the feeding group, and if the next batch of pipelines to be detected are required to be detected, the pipelines to be detected can be fed through the feeding group, and then the detection is carried out;
besides, the third spring 18 can buffer the sealing plate 17 when the pipeline is clamped, and clamp the pipeline with smaller length gap, so that the applicability is improved to a certain extent, the pipeline with smaller length gap can have thickness, in order to ensure that when the push piece 16 pushes the contact plate 8 to move, the pipeline with defective air tightness clamped between the two sealing plates 17 can smoothly roll towards the left side of the water tank 1 through the receiving plate 10, therefore, the baffle plate 12 is arranged, can firstly fall on the baffle plate 12 after the pipeline falls and then roll on the receiving plate 10, the baffle plate 12 rotates around the rotating shaft and compresses the first torsion spring 13 when the pipeline is contacted with the baffle plate 12 when the supporting frame 4 rotates clockwise, if the clamped pipeline is thicker, the angle of upward rotation of the baffle plate 12 is required to be increased, and if the angle of rotation of the baffle plate 12 is larger, when the first cylinder 15 is started, the right end of the baffle 12 may still contact the pipeline, or just be separated from contact, then the pipeline directly falls down on the baffle 12 at the initial position after the two sealing plates 17 are separated from the pipeline, so that the pipeline may not fall down to the inside of the water tank 1, therefore, the material receiving plate 10 is in an H shape, when the support frame 4 rotates, the contact plate 8 firstly contacts with the right end of the material receiving plate 10, so that the material receiving plate 10 slides along the fixed plate 9 and compresses the second spring 11, thereby driving the baffle 12 to perform a certain degree of abdication, when the pipeline contacts with the baffle 12, the rotation angle of the baffle 12 is reduced, when the contact plate 8 does not contact with the material receiving plate 10, the baffle 12 is reset under the action of the first spring 7, and then the pipeline is smoothly received;
the pipeline to be detected is fed through the blanking group, then continuous and rapid detection is carried out on the rotation of a plurality of pipelines, when the defective pipeline is detected, the thumb needs to start the first cylinder 15, the defective pipeline can be automatically lowered through the push plate 16 and the contact plate 8, so that the defective pipeline is screened, if the defect pipeline is not damaged, the blanking group is used for blanking in sequence, when the detection is carried out, the dismounting and mounting of the two ends of the pipeline are not needed, and the pipeline is not needed to be put into water and fished out manually for many times, so that the labor intensity of manpower is reduced, and the detection efficiency is improved.

after the two sealing plates 17 clamp the pipeline, the limiting group can limit the pipeline at the rear, so that the pipeline at the rear is prevented from being clamped away by the sealing plates 17, and when the sealing plates 17 drive the pipeline to rotate, the limiting group can also give way to the clamped away pipeline, and the pipeline at the rear automatically rolls leftwards in a state that the discharging plate 19 is low on the left and high on the right, so that feeding is sequentially performed;
when all the pipes are fed, the first detected pipe will rotate a circle if the pipe is not defective, if the air tightness is defective, the pipe will roll to the outside through the receiving plate 10, the second cylinder 20 needs to be started, the left end of the discharging plate 19 is higher than the right end, so that the feeding state is changed into the discharging state, when the left end of the discharging plate 19 is higher than the right end, the two sealing plates 17 and the connecting shell 6 and the pipe with the air tightness being defective rotate to the side edge of the discharging block 22, at the moment, the two discharging blocks 22 are contacted with the contact plate 8 again, and the two first springs 7 are compressed to the limit position, at the moment, the length between the two sealing plates 17 is longer than the length of the pipe, at the moment, the pipe will drop directly, and then roll to the right side of the water tank 1 through the discharging plate 19, so that the discharging of the pipe is completed.

A rapid detection process for air tightness of a high-pressure water heater, which comprises the following steps:
step one: the telescopic length of the third cylinder 28 is adjusted according to the length of the pipeline to be detected, so that the length between two opposite sealing plates 17 is slightly larger than the length of the pipeline to be detected;
step two: changing the blanking group into a feeding state, feeding the pipeline to be detected through the limiting group, and clamping the pipeline through the cooperation of the blanking block 22 and the contact plate 8;
step three: when the support frame 4 rotates, the air tightness of the pipeline is continuously detected, so that the defective pipeline and the pipeline without defects are subjected to blanking;
step four: repeating the first step, the second step and the third step.
Working principle: firstly, the pipeline to be detected is fed through a blanking group, two ends of the pipeline are positioned between two opposite sealing plates 17 after the feeding is finished, the pipeline can be buffered to a certain degree when being clamped by the sealing plates 17 and a third spring 18, when the pipeline is detected, the motor 3 and the air pump 5 are required to be started, the air pump 5 discharges the outside air into the support frame 4, because the support frame 4 is hollow, the air enters the support frame 4 and then enters the interior of the pipeline through the connecting shell 6 and the ventilation holes formed in the sealing plates 17, the motor 3 supports the motor 3 through the support plate 2, the support frame 4 and the air pump 5 are driven to rotate when the motor 3 rotates, the water tank 1 is filled with water, a worker only needs to observe the pipeline below the first air cylinder 15, when the support frame 4 drives the pipeline to be detected to be immersed in water, if the pipeline is cracked, air bubbles are generated, which indicates that the air tightness of the pipeline is defective, and as the motor 3 rotates, when the pipeline comes out of water and rotates to one side of the push plate 16, a worker starts the first air cylinder 15, the first air cylinder 15 is supported by the first L-shaped rod 14, the first air cylinder 15 shortens and drives the push plate 16 to contact with the contact plate 8 at one side of the defective pipeline, the two contact plates 8 are pushed by the two push plates 16 to move towards the two motors 3 respectively, the two contact plates 8 are driven to move by the two contact plates 8, the two connection shells 6 are driven to move by the two connection shells 6, the sealing plate 17 is driven to move by the two connection shells 6, at the moment, the third spring 18 is slowly relaxed, after the third spring 18 is completely relaxed, the push plate 16 continues to push the contact plate 8 to move each time, the rear end of the connection shells 6 slides towards the support frame 4 and compresses the first spring 7, after the first spring 7 is compressed to the limit position, the two sealing plates 17 are not contacted with the pipeline, at the moment, the defective pipeline can directly fall onto the baffle plate 12, then the first air cylinder 15 is reset, the sealing plates 17 and the connecting shell 6 are reset successively under the elastic action of the first spring 7 and the third spring 18, the baffle plate 12 and the material receiving plate 10 are obliquely arranged, and the defective pipeline falling onto the material receiving plate 10 can directly roll to one side, so that the air tightness detection and the blanking work are completed;
after the first air cylinder 15 is started, the defective pipelines automatically fall through the pushing piece 16 and the contact plate 8, at the moment, a worker only needs to observe whether the next pipeline can generate bubbles in water or not, if the air tightness of all the pipelines is free of problems, the first air cylinder 15 is not required to be started, after the detected pipelines rotate for a circle, the defective pipelines can be fed one by one through the feeding group, and if the next batch of pipelines to be detected are required to be detected, the pipelines to be detected can be fed through the feeding group, and then the detection is carried out;
besides, the third spring 18 can buffer the sealing plate 17 when the pipeline is clamped, and clamp the pipeline with smaller length gap, so that the applicability is improved to a certain extent, the pipeline with smaller length gap can have thickness, in order to ensure that when the push piece 16 pushes the contact plate 8 to move, the pipeline with defective air tightness clamped between the two sealing plates 17 can smoothly roll towards the left side of the water tank 1 through the receiving plate 10, therefore, the baffle plate 12 is arranged, can firstly fall on the baffle plate 12 after the pipeline falls and then roll on the receiving plate 10, the baffle plate 12 rotates around the rotating shaft and compresses the first torsion spring 13 when the pipeline is contacted with the baffle plate 12 when the supporting frame 4 rotates clockwise, if the clamped pipeline is thicker, the angle of upward rotation of the baffle plate 12 is required to be increased, and if the angle of rotation of the baffle plate 12 is larger, when the first cylinder 15 is started, the right end of the baffle 12 may still contact the pipeline, or just be separated from contact, then the pipeline directly falls down on the baffle 12 at the initial position after the two sealing plates 17 are separated from the pipeline, so that the pipeline may not fall down to the inside of the water tank 1, therefore, the material receiving plate 10 is in an H shape, when the support frame 4 rotates, the contact plate 8 firstly contacts with the right end of the material receiving plate 10, so that the material receiving plate 10 slides along the fixed plate 9 and compresses the second spring 11, thereby driving the baffle 12 to perform a certain degree of abdication, when the pipeline contacts with the baffle 12, the rotation angle of the baffle 12 is reduced, when the contact plate 8 does not contact with the material receiving plate 10, the baffle 12 is reset under the action of the first spring 7, and then the pipeline is smoothly received;
the pipeline to be detected is fed through the blanking group, then continuous and rapid detection is carried out on the rotation of a plurality of pipelines, when the defective pipeline is detected, the thumb needs to start the first cylinder 15, the defective pipeline can be automatically lowered through the push plate 16 and the contact plate 8, so that the defective pipeline is screened, if the defect pipeline is not damaged, the blanking group is used for blanking in sequence, when the detection is carried out, the dismounting and mounting of the two ends of the pipeline are not needed, and the pipeline is not needed to be put into water and fished out manually for many times, so that the labor intensity of manpower is reduced, and the detection efficiency is improved.
