In the process of upward transferring of the centrifugal pump, the universal wheels 2 can rotate, so that the centrifugal pump can shake finally, and in order to prevent shaking, the detection process of air tightness is ensured; as a further scheme of the present invention, the supporting mechanism includes a plurality of rubber pads 29, sliding rods 30 are fixedly disposed at upper ends of the plurality of rubber pads 29, the sliding rods 30 are slidably disposed on the bottom plate 1, first springs 31 are disposed on the sliding rods 30 between upper end surfaces of the rubber pads 29 and lower end surfaces of the bottom plate 1, an upper end portion of each sliding rod 30 is fixedly disposed with a connecting frame 32, a U-shaped rod 9 is fixed at an upper end surface on the left side of the connecting frame 32, second steel wire ropes 33 are fixedly disposed at lower end surfaces on the left and right sides of the connecting frame 32, the second steel wire ropes 33 bypass pulley frames 34, and upper end portions of the second steel wire ropes 33 are fixedly disposed at lower end surfaces of the sliding plates 3, and the pulley frames 34 are fixedly disposed at upper end surfaces of the bottom plate 1; when the device works, when the output end of the electric push rod 6 pushes the sliding plate 3 to move upwards (shown in fig. 2, fig. 3 and fig. 4), then the sliding plate 3 drives the second steel wire rope 33 to move upwards, then the second steel wire rope 33 bypasses the pulley frame 34 to pull the connecting frame 32 to move downwards, then the connecting frame 32 pushes the plurality of sliding rods 30 to move downwards, so that the rubber pads 29 fixedly connected with the bottom ends of the sliding rods 30 move downwards, then the rubber pads 29 contact the ground downwards and support the whole production detection device (at this time, the first springs 31 are in a stretching state, the first springs 31 play a role of resetting for the connecting frame 32), so that the universal wheel 2 which is easy to move leaves the ground, but the rubber pads 29 instead support the production detection device, thereby preventing the universal wheel 2 from rotating due to the collision of human factors to the production detection device in the process of upward transferring the centrifugal pump, finally, the centrifugal pump is shaken, so that the risk that the centrifugal pump drops is possibly caused, and the generated shaking influences the tightness of the inlet and the outlet of the centrifugal pump, so that the detection effect of the air tightness of the centrifugal pump is influenced.

The air tightness of the centrifugal pump is qualified and unqualified, so that the automation degree is improved, and the detection work of staff is facilitated; as a further scheme of the present invention, the triggering mechanism includes a floating plate 35, the floating plate 35 is slidably disposed in the U-shaped tube 12, a curved bar 36 is fixedly disposed on an upper end surface of the floating plate 35, the other end of the curved bar 36 is slidably disposed in a triggering rod 37, a sensor 38 is fixedly disposed at a bottom end of the triggering rod 37, and the sensor 38 is fixedly disposed on a lower end surface of the sliding plate 3; in operation, when the liquid in the U-shaped tube 12 is pressed by the gas to slide towards the upper end of the right side of the U-shaped tube 12 (see fig. 2, 5, and 7), the floating plate 35 in the U-shaped tube 12 will be pushed by the liquid to move upwards, so that the curved rod 36 fixedly connected to the upper end of the floating plate 35 will move upwards, and the other end of the curved rod 36 will slide upwards in the trigger rod 37, and when the curved rod 36 slides upwards in the trigger rod 37 to a qualified area, the sensor 38 fixedly connected to the lower end of the trigger rod 37 receives a signal to control the first electromagnet 21 to be powered off, otherwise, the first electromagnet 21 will continue to be powered on.

The centrifugal pump is heavy, so that the centrifugal pump is inconvenient to move during disassembly and is convenient for workers to disassemble; as a further scheme of the present invention, the rotating mechanism includes a motor 39, a rear side end of the motor 39 is fixedly disposed on a lower end surface of the sliding plate 3 through an L-shaped plate 40, a front side end of the motor 39 is slidably disposed on a rear side end of the electric push rod 6, an upper end portion of the output shaft 44 is fixedly disposed with a rotary table 41, the rotary table 41 is penetratingly disposed with a through hole 42, a circle center position of the through hole 42 and a circle center position of the batter post 14 are the same axial line, a circular groove 43 is disposed on a circumferential end surface of the output shaft 44, and a first fixing ring 15 is slidably disposed in the circular groove 43; the during operation, when the up end up of sliding plate 3 moves to the up end parallel and level with U-shaped platform 4 (combine fig. 8, shown in fig. 9), this moment, if the leakproofness of centrifugal pump is unqualified then dismantle the centrifugal pump through the manual work, for the convenience of manual work to the dismantlement of centrifugal pump, accessible starter motor 39 this moment, thereby make motor 39 drive carousel 41 through the rotation of output shaft 44 and rotate, and then can make the centrifugal pump of carousel 41 upper end carry out angle regulation, make things convenient for the manual work to the disassembling of centrifugal pump, thereby avoided rotating the centrifugal pump through the manual work, cause the problem that intensity of labour is big to take place, the manual work has been prevented simultaneously when rotating the centrifugal pump, carelessly cause the centrifugal pump landing to take place under the workstation and then cause the condition of injury to the staff.

The working principle is as follows: when the device is used, firstly, a centrifugal pump to be detected is placed on a rotating disc 41 on a production detection device by staff, a mounting hole on a base plate 1 of the centrifugal pump is manually aligned to a through hole 42, then, an inlet of the centrifugal pump is hermetically connected with an upper end port of a first pipeline 11, and meanwhile, an outlet of the centrifugal pump is hermetically connected with an upper end port on the left side of a U-shaped pipe 12; then the electric push rod 6 is manually started, at this time, the output end of the electric push rod 6 pushes the sliding plate 3 to move upwards (shown in fig. 2, fig. 3 and fig. 4), then the sliding plate 3 drives the second steel wire rope 33 to move upwards, then the second steel wire rope 33 bypasses the pulley frame 34 to pull the connecting frame 32 to move downwards, then the connecting frame 32 pushes the plurality of sliding rods 30 to move downwards, so that the rubber pads 29 fixedly connected to the bottom ends of the sliding rods 30 move downwards, then the rubber pads 29 contact the ground downwards and support the whole production detection device (at this time, the first springs 31 are in a stretching state, the first springs 31 play a role of resetting for the connecting frame 32), so that the universal wheel 2 which is easy to move leaves the ground, but the rubber pads 29 instead support the production detection device, so that the centrifugal pump can avoid the universal wheel 2 from rotating due to the collision of human factors on the production detection device in the process of transferring upwards, the centrifugal pump is shaken finally, so that the risk that the centrifugal pump falls off is possibly caused, and meanwhile, the generated shake influences the tightness of an inlet and an outlet of the centrifugal pump, so that the detection effect of the air tightness of the centrifugal pump is influenced; meanwhile, when the output end of the electric push rod 6 pushes the sliding plate 3 to move upwards (as described in conjunction with fig. 2, 5, 6 and 7), and the connecting frame 32 moves downwards, the U-shaped rod 9 fixed on the upper end surface of the connecting frame 32 moves downwards, then the sealing plate 8 fixedly connected with the other end of the U-shaped rod 9 moves downwards in the air cylinder 7, so that the sealing plate 8 presses air in the air cylinder 7 into the first pipeline 11 (when the connecting frame 32 moves upwards, the air cylinder 7 sucks air through the one-way air inlet valve 10 to prepare for the next detection of the centrifugal pump), then the air enters the centrifugal pump and then enters the U-shaped pipe 12 through the centrifugal pump, and the liquid in the U-shaped pipe 12 is pressed by the air to slide towards the upper right end of the U-shaped pipe 12 due to the liquid in the U-shaped pipe 12; therefore, the air tightness of the centrifugal pump is judged according to the upward sliding height of the liquid in the U-shaped pipe 12, so that the detection of the centrifugal pump is effectively guaranteed, meanwhile, the air tightness of the centrifugal pump is known to a certain extent before disassembly and assembly, the problem that leakage exists during installation if the air tightness is unqualified after installation can be timely known, and the problem that the centrifugal pump is replaced without knowing whether the air tightness of the centrifugal pump is qualified is solved; meanwhile, when the liquid in the U-shaped tube 12 is pressed by the gas and slides towards the upper end of the right side of the U-shaped tube 12 (see fig. 2, 5 and 7), the floating plate 35 in the U-shaped tube 12 moves upwards under the thrust of the liquid, so that the curved rod 36 fixedly connected with the upper end of the floating plate 35 moves upwards, the other end of the curved rod 36 slides upwards in the trigger rod 37, and when the curved rod 36 slides upwards in the trigger rod 37 to a qualified range area, the inductor 38 fixedly connected with the lower end of the trigger rod 37 receives a signal to control the first electromagnet 21 to be powered off, otherwise, the first electromagnet 21 continues to be powered on; meanwhile, when the output end of the electric push rod 6 pushes the sliding plate 3 to move upwards (see fig. 2, 8, 9 and 10), at this time, because the first electromagnet 21 and the second electromagnet 22 are in an adsorption state, and the second electromagnet 22 is limited by the L-shaped clamping plate 24, then the first steel wire rope 19 fixedly connected to the upper end of the first electromagnet 21 will bypass the square groove 20 to pull the second fixing ring 16 to move upwards, and then the baffle 17 fixedly connected to the second fixing ring 16 will push the first fixing ring 15 to move upwards, so that the batter post 14 fixedly connected to the upper end surface of the first fixing ring 15 moves upwards to pass through the through hole 42 and is finally clamped in the mounting hole at the bottom end surface of the centrifugal pump, thereby being beneficial to fixing the centrifugal pump by the batter post 14 when the sliding plate 3 moves upwards, so as to limit the centrifugal pump, and further stabilizing the stability of the centrifugal pump on the production detection device, meanwhile, the through hole 42 is arranged, so that the centrifugal pump can be positioned in time conveniently, and the pipeline connection of an inlet and an outlet of the centrifugal pump is facilitated; because the upward displacement of the sliding plate 3 is large, when the sliding plate 3 continues to move upward, the L-shaped inserting plate 28 fixed on the lower end surface of the sliding plate 3 moves upward at the same time, so that the inclined block 27 fixedly connected with the front side end of the L-shaped inserting plate 28 extrudes the L-shaped clamping plate 24, then the L-shaped clamping plate 24 slides in the second chute 25 toward the other end of the third gas spring 26, and simultaneously extrudes the third gas spring 26 (the third gas spring 26 plays a role in resetting for the L-shaped clamping plate 24), then the second electromagnet 22 does not receive the limiting of the clamping plate and starts to move upward, and at this time, the second gas spring 23 fixedly connected with the lower end of the second electromagnet 22 is stretched (the second gas spring 23 plays a role in resetting for the second electromagnet 22), so that the inclined column 14 can always limit and stabilize the centrifugal pump when the sliding plate 3 moves upward; when the curved rod 36 slides upwards in the trigger rod 37 to the region of the qualified range 371 (the qualified range 371 and the unqualified range 372), the first electromagnet 21 is powered off, then the second electromagnet 22 is reset by the tensile force of the second gas spring 23, and the second fixing ring 16 is reset by the tensile force of the first gas spring 18, so that the inclined column 14 slides downwards in the ring groove 43 and resets without limiting the centrifugal pump, and the centrifugal pump can be conveniently assembled and disassembled; when the upper end face of the sliding plate 3 upwards moves to be flush with the upper end face of the U-shaped table 4 (shown in fig. 8 and fig. 9), at this time, if the sealing performance of the centrifugal pump is unqualified, the centrifugal pump is disassembled manually, and the centrifugal pump is convenient to disassemble manually, the motor 39 can be started at this time, so that the motor 39 drives the turntable 41 to rotate through the rotation of the output shaft 44, further the angle of the centrifugal pump at the upper end of the turntable 41 can be adjusted, the manual disassembly of the centrifugal pump is convenient, the problem of high labor intensity caused by the manual rotation of the centrifugal pump is avoided, and meanwhile, the situation that the centrifugal pump accidentally slides down to the lower part of the workbench and further causes injury to workers is prevented when the centrifugal pump is rotated manually (the direction in the text is shown according to the direction of a full-length fig. 2).
