Description

Technical Field

[0001] This utility model relates to the field of fault detection technology, and in particular to an industrial instrument fault detection device. Background Technology

[0002] After long-term use, flow meters and industrial instruments may experience measurement deviations due to process changes, environmental interference, or equipment aging. Regular inspections can promptly detect and correct errors, preventing production abnormalities or safety hazards caused by inaccurate data.

[0003] Existing flow meter fault detection methods typically involve filling the flow pipe with a certain amount of gas. If there is a leak, the resulting bubbles will float on the liquid surface, allowing for visual inspection. However, its main drawback is that it relies on visual inspection, meaning that the detection results are easily affected by human factors. To better address these issues, promote the development of industry technology, and enhance core competitiveness, this application proposes a new structural design that differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an industrial instrument fault detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An industrial instrument fault detection device includes a housing. A support block is fixedly connected to the inner top wall of the housing. A groove is formed on the top of the support block. Two sliding grooves are formed on the bottom of the housing, and a slider is movably connected in each of the two sliding grooves. A power component is provided at the bottom of the housing to drive the two sliders to move relative to or away from each other. A clamping block is fixedly connected to the top of the slider. A through hole is formed in the middle of the clamping block. A bellows is fixedly connected to one side of the clamping block at a position communicating with the through hole. An air inlet is formed on one side of the housing. A connecting pipe is fixedly connected to the air inlet. A piston block is movably connected inside the connecting pipe. A spring is fixedly connected to one side of the piston block, and the spring is fixed to the end of the connecting pipe.

[0007] As a further embodiment of this utility model, the power assembly includes two fixing plates, which are fixed to the bottom inner wall of the housing by bolts. A bidirectional threaded rod is movably connected between the two fixing plates, and the bidirectional threaded rod is threadedly connected to the slider. A motor is fixedly connected to one of the fixing plates, and one end of the motor output shaft is fixed to the bidirectional threaded rod.

[0008] As a further embodiment of this utility model, a connection port is provided on one side of the housing, and an air inlet pipe is fixedly connected to the connection port, and the corrugated pipe is fixedly connected to the air inlet pipe at an adjacent position.

[0009] As a further improvement of this invention, sealing gaskets are fixedly connected to the clamping surfaces of both clamping blocks.

[0010] As a further embodiment of this invention, a magnetic block is provided in the groove via a bolt.

[0011] As a further embodiment of this utility model, a fixing ring is fixedly connected to the inner wall of the first end of the connecting pipe, and the inner diameter of the fixing ring is smaller than the diameter of the piston block.

[0012] As a further embodiment of this utility model, a door panel is movably connected to one side of the housing, and the housing and the door panel are detachably fixed by a latch.

[0013] As a further improvement of this utility model, an observation opening is provided on the door panel, and an observation window is fixed inside the observation opening.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, air leakage is detected by venting air into the flow meter pipeline. When the flow meter pipeline leaks, gas enters the sealed housing, and the piston block moves outward along the connecting pipe under pressure. By directly observing whether the piston block has moved, the operator can help determine whether the flow meter pipeline is leaking. The detection method is intuitive and simple, reduces the difficulty of detection, and improves detection efficiency.

[0016] 2. In this utility model, the bellows that can extend and retract with the movement of the clamping block ensures that the air intake process of the device is not affected by the movement of the clamping block. It can also restrict the position of the piston block through the fixing ring to prevent the piston block from coming out of the connecting pipe.

[0017] 3. In this utility model, the use of groove and magnetic block can quickly achieve the initial positioning of the flow meter. With the addition of two clamping blocks, the position of the flow meter can be further restricted. The sealing gasket on the clamping surface of the clamping block can also increase the sealing between the clamping block and the pipes at both ends of the flow meter, preventing gas leakage during the detection process and further ensuring the accuracy of the detection results.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] Reference Figures 1-5 An industrial instrument fault detection device includes a housing 2. A support block 6 is fixed to the top inner wall of the housing 2 by bolts. A groove 19 is opened on the top of the support block 6. A magnetic block 18 is bolted into the groove 19. The flow meter to be tested is placed into the groove 19 on the top of the support block 6, so that the magnetic block 18 contacts the flow meter to achieve preliminary positioning. Two sliding grooves 8 are opened at the bottom of the housing 2. A slider 7 is slidably connected in each of the two sliding grooves 8. A power component is provided at the bottom of the housing 2 to drive the two sliders 7 to move relative to each other or in opposite directions.

[0026] In this utility model, the power assembly includes two fixing plates 9, which are fixed to the bottom inner wall of the housing 2 by bolts. A bidirectional threaded rod 12 is rotatably connected between the two fixing plates 9, and the bidirectional threaded rod 12 is threadedly connected to the slider 7. A motor is fixed to one of the fixing plates 9 by bolts. The motor is a self-locking geared motor, model 57HS7630B4D8, and one end of the motor output shaft is fixed to the bidirectional threaded rod 12. A clamping block 11 is fixed to the top of the slider 7 by bolts. When the motor rotates, the bidirectional threaded rod 12 drives the two sliders 7 to move towards the middle along the slide groove 8, thereby causing the clamping blocks 11 to move towards the middle and contact the two ends of the flow meter pipe openings.

[0027] It should be noted that a through hole 13 is provided in the middle of the clamping block 11. A bellows 10 is fixed at one side of the clamping block 11, which is connected to the through hole 13. One end of the bellows 10 passes through the through hole 13 and can extend and retract with the movement of the clamping block 11. A connection port is provided on one side of the housing 2. An air inlet pipe 5 is fixedly connected to the connection port. The bellows 10 is fixedly connected to the air inlet pipe 5 at the adjacent position, connecting the air inlet pipe 5 to the external air supply equipment. External high-pressure gas enters the flow meter pipeline through the air inlet pipe 5 and the bellows 10. An air inlet is provided on one side of the housing 2. A connecting pipe 4 is fixedly connected to the air inlet. The connecting pipe 4 is made of transparent PVC or PTFE material. A piston block 16 is slidably connected inside the connecting pipe 4. A spring 15 is welded to one side of the piston block 16. The elastic coefficient of the spring 15 is less than 5. N / m, and the spring 15 is fixed to the end of the connecting pipe 4. When there is a leak in the flow meter pipeline, the leaked gas enters the sealed housing 2. At this time, the piston block 16 is under pressure and moves outward along the connecting pipe 4, and the spring 15 contracts. By observing whether the piston block 16 is displaced, the staff can help judge whether the flow meter pipeline is leaking.

[0028] In particular, sealing gaskets 14 are bonded to the clamping surfaces of both clamping blocks 11. The sealing gaskets 14 increase the sealing between the clamping blocks 11 and the pipes at both ends of the flow meter. A fixing ring 17 is fixed to the inner wall of the first end of the connecting pipe 4 by bolts. The inner diameter of the fixing ring 17 is smaller than the diameter of the piston block 16. The fixing ring 17 can prevent the piston block 16 from coming out of the connecting pipe 4. A door panel 3 is rotatably connected to one side of the housing 2. The housing 2 and the door panel 3 are tightly fixed by a latch 1. An observation port is opened on the door panel 3. An observation window is fixed inside the observation port. The observation window allows the staff to observe the internal situation without opening the door panel 3. The door panel 3 and the housing 2 are sealed together by a rubber gasket.

[0029] Working principle: When it is necessary to detect whether the flow pipe of the flow meter is leaking, first place the flow meter to be tested into the groove 19 on the top of the support block 6, so that the magnetic block 18 contacts the flow meter to achieve initial positioning.

[0030] Then start the motor. The motor rotation causes the bidirectional threaded rod 12 to drive the two sliders 7 to move towards the middle along the slide groove 8, thereby causing the clamping blocks 11 to move towards the middle and contact the pipe openings at both ends of the flow meter. The bellows 10 expands and contracts following the movement of the clamping blocks 11. The sealing gasket 14 increases the sealing between the clamping blocks 11 and the pipes at both ends of the flow meter.

[0031] Then, the air inlet pipe 5 is connected to the external air supply equipment. The external high-pressure gas enters the flow meter pipeline through the air inlet pipe 5 and the corrugated pipe 10. When there is a leak in the flow meter pipeline, the leaked gas enters the sealed housing 2. At this time, the piston block 16 is under pressure and moves outward along the connecting pipe 4, and the spring 15 contracts. By observing whether the piston block 16 is displaced, the staff can help judge whether the flow meter pipeline is leaking.

[0032] Furthermore, the terms "set up," "equipped with," "connected," "linked," and "socketed" should be interpreted broadly. For example, they can refer to a fixed connection; a mechanical connection; a direct connection; or an indirect connection via an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
