Description

Technical Field

[0001] The present invention relates to the technical field of transformer substation operation and maintenance, more particularly to the technical field of transformer respirator operation and maintenance, and more particularly to a transformer respirator replacement device. Background Art

[0002] The function of the transformer respirator is to absorb moisture from the air that enters the oil pillow plastic bag and diaphragm, and to remove and dry debris and moisture from the air that enters the transformer oil storage cabinet due to changes in the transformer oil temperature, so as to prevent the transformer from getting damp, thereby ensuring the stability of the insulation strength of the transformer oil.

[0003] When the transformer expands due to heat, the transformer oil in the transformer also expands, and then the volume increases and the excess air inside the transformer is discharged; when the transformer oil temperature drops and contracts, air is sucked in from the outside. When the outside air is sucked in, the transformer oil in the oil storage box filters the outside air, and then the silica gel absorbs the moisture that is not filtered out, so that the transformer oil in the transformer is not invaded by moisture in the outside air, so that its moisture content is always within the standard.

[0004] The transformer respirator usually consists of an iron pipe and a glass container, in which a desiccant (usually silica gel) is placed, and an oil cup is set at the bottom of the glass container. Since the desiccant, such as silica gel particles, will absorb too much moisture and lose its ability to absorb moisture again after running for too long, it is necessary to replace the desiccant particles in the transformer respirator, that is, to remove the ineffective desiccant particles and replace them with desiccant particles with good adsorption performance.

[0005] In the prior art, the process of replacing the transformer respirator is quite cumbersome and time-consuming. First, two people are usually required to install and disassemble the respirator, one of whom uses a wrench to install and disassemble the bolts between the respirator and the pipeline, while the other person holds the bottom of the respirator with his hand to prevent it from falling suddenly after disassembly. However, as is well known, most general respirators weigh 30 kilograms, and the oil cup and the body are glass parts. It is easy for people to quickly fatigue their hands when holding such a heavy respirator for a long time. Once negligent, the respirator is likely to fall to the ground and be broken. Secondly, in the prior art, the time for installing or disassembling the respirator is usually about 25 minutes per phase. If special circumstances such as bolt rust occur, it will make disassembly more difficult and take longer. Furthermore, after the respirator is disassembled, it is necessary to manually lift the respirator and turn it upside down to discharge the damp silica gel particle desiccant inside, and then turn the respirator over again to load the new silica gel particle desiccant into the respirator. Because the respirator is heavy, the operation is quite inconvenient, which consumes the physical strength of the personnel and increases the work intensity. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a transformer breather replacement device, which has a simple structure and is easy and stable to operate, thereby greatly reducing the operating intensity and operating time of operators.

[0007] The present invention discloses a transformer respirator replacement device, comprising: a main shaft, a fixing component which is arranged at the top of the main shaft for transverse rotation, and a flipping component which is arranged at the bottom of the main shaft for longitudinal rotation.

[0008] The flip assembly comprises:

[0009] A longitudinal connecting plate, on which a transverse shaft is transversely arranged;

[0010] A second cantilever is formed by extending transversely from the top of the longitudinal connecting plate, a second arc-shaped slot is formed at one end of the second cantilever away from the top of the longitudinal connecting plate, a second rotating hole and a second pivot hole are longitudinally formed on the left and right sides of the second arc-shaped slot, and a second hollow slot is transversely formed on the second cantilever;

[0011] A second buckle, comprising a second body, a second lug extending from the right side of the second body and having a second through hole thereon, a second locking groove laterally formed on the left side of the second body, and a second arc-shaped pressing groove matched with the second arc-shaped buckle groove further formed on the second body; and

[0012] A support frame disposed transversely at the bottom end of the longitudinal connecting plate;

[0013] The second lug of the second fastener is inserted into the second hollow groove, and the second pivot passes through the second pivot hole and the second through-hole, so that the second fastener can rotate around the second pivot. A second rotating shaft is arranged in the second rotating hole, and the second swing rod of the second locking nail composed of a second swing rod and a second hooking part formed at one end of the second swing rod extends horizontally into the second hollow groove and is fixedly connected to the second rotating shaft. The second locking nail is arranged so that one end of the second swing rod close to the second hooking part can be arranged in the second locking groove, and the second hooking part can be hooked on a surface of the second main body, thereby forming an arc-shaped locking space between the second arc-shaped slot and the second arc-shaped pressing groove.

[0014] The transformer breather replacement device of the present invention ingeniously fixes the fixing component on the pipeline in a quick-release manner, and then sets the breather on the flip component through the cooperation of the main shaft that rotates horizontally relative to the fixing component and the flip component arranged at the bottom of the main shaft, and replaces the silica gel particles in the breather by flipping the flip component, so the operation is simple, easy and convenient, which greatly improves the replacement efficiency and reduces the labor intensity.

[0015] Preferably, an external thread is formed on the first axial end of the main shaft, and an internal thread matching the external thread is formed in the axial hole of the fixing component.

[0016] Preferably, an anti-slip pad is provided on the inner side surface of the first arc-shaped groove. After the anti-slip pad is provided, the degree of compression between the first arc-shaped groove and the pipeline can be further enhanced, thereby preventing the transformer breather replacement device carrying the above-mentioned transformer breather from slipping on the pipeline. Specifically, the fixing component is prevented from slipping on the pipeline, thereby improving the reliability of the connection and ensuring the safety of the operation.

[0017] Further preferably, an anti-slip pad is also provided on the first arc-shaped pressing groove matched with the first arc-shaped clamping groove, thereby achieving a similar technical effect.

[0018] Preferably, an anti-slip pad is provided on the inner side surface of the second arc-shaped slot. After the anti-slip pad is provided, the degree of compression between the second arc-shaped slot and the transformer breather can be further enhanced, thereby preventing the transformer breather from slipping up and down relative to the second cantilever of the transformer breather replacement device, thereby improving the reliability of the fixed connection between the two and ensuring the operational safety during the replacement of the silica gel particle desiccant in the breather.

[0019] Preferably, an anti-slip pad is also provided on the second arc-shaped pressing groove matched with the second arc-shaped groove, thereby achieving a technical effect similar to that of the second arc-shaped groove.

[0020] Preferably, the transverse axis is arranged in the middle of the longitudinal direction of the longitudinal connecting plate, so that when flipping up and down relative to the transverse axis hole, the operator can flip the entire flip assembly and the transformer breather arranged on the flip assembly without any effort.

[0021] Preferably, a bearing is arranged on the transverse shaft of the flip assembly, and the transverse shaft is rotatably arranged in the transverse shaft hole by means of the bearing. The above-mentioned bearing can further reduce the friction resistance generated when the flip assembly flips, thereby saving more effort when flipping.

[0022] Preferably, the cross-sectional shape of the longitudinal connecting plate is rectangular. Such a longitudinal connecting plate with a rectangular cross-sectional shape makes it easy for an operator to hold the longitudinal connecting plate with his hands, thereby facilitating the application of external force to flip the longitudinal connecting plate up and down, thereby improving the convenience of operation.

[0023] Preferably, a reinforcing rib is formed on the longitudinal connecting plate at a position corresponding to the transverse axis, so as to strengthen the structural strength of the entire longitudinal connecting plate and prevent the longitudinal connecting plate from being broken at the position of the transverse axis when the operator flips the longitudinal connecting plate.

[0024] Preferably, the invention further comprises a wrench, which comprises a mounting cylinder fixedly sleeved on the first axial end of the spindle and located above the cylindrical body, and a handle radially extending from the circumferential surface of the mounting cylinder. By rotating the handle of the wrench, the operator can easily rotate the spindle according to the lever principle, thereby realizing the axial movement of the spindle relative to the cylindrical body.

[0025] Preferably, the support frame is an annular support frame, which is light in weight and allows some components of the transformer breather to extend from the hollow portion of the annular support frame, so that the breather can be easily disassembled, and the discarded silica gel particles can be quickly and conveniently removed and filled with new silica gel particles.

[0026] Preferably, the mounting seat on the second axial end of the main shaft is arranged to be rotatable around the axis of the main shaft. In the above operation process, if the longitudinal gap between the respirator and the pipeline is relatively small and the respirator cannot be directly flipped, the main shaft can be rotated without rotating the flip assembly together with the main shaft, that is, the flip assembly and the respirator fixed thereon remain stationary. Since the cylinder cannot move up and down relative to the pipeline, the rotational action causes the main shaft to move axially up and down relative to the cylinder, so that the longitudinal gap between the respirator and the pipeline can be widened, and then the respirator can be directly flipped up and down.

[0045] The first shaft end 12 of the main shaft 10 is rotatably arranged in the shaft hole 224 by means of threaded engagement; the first lug 2322 of the first clip 23 is inserted into the first hollow groove 202, and the first pivot 25 passes through the first pivot hole 28 and the first through hole 23222, so that the first clip 23 can rotate around the first pivot 25, and the first rotating shaft 27 is arranged in the first rotating hole 21, which is connected by the first swing rod 292 and the first hook portion 29 formed at one end of the first swing rod 292. The first swing rod 292 of the first locking nail 29 formed by the first arc-shaped locking nail 29 is laterally extended into the first hollow groove 202 and is fixedly connected to the first rotating shaft 27. The first locking nail 29 is configured so that the end of the first swing rod 292 close to the first hooking portion 294 is arranged in the first locking groove 2326, and the first hooking portion 294 is hooked on a surface of the first body 232, so that an arc-shaped locking space is formed between the first arc-shaped card slot 26 and the first arc-shaped pressing slot 2324, which is used to lock the transformer The pipe 60 above the respirator 50 is locked in the space; the second lug 314 of the second fastener 31 is inserted into the second hollow groove 368, and the second pivot 33 passes through the second pivot hole 364 and the second through hole 3142, so that the second fastener 31 can rotate around the second pivot 33, and the second rotating shaft 35 is set in the second rotating hole 366.

[0046] The transverse shaft 34 is rotatably disposed in a transverse shaft hole 1422 opened on the mounting seat 142 of the second shaft end 14 of the main shaft 10 .

[0047] In the above structure, the first arc-shaped slot 26 at the end of the first cantilever 24 cooperates with the first fastener 23 and the first rotating shaft 27, the first pivot 25 and the first locking nail 29, so that these components together form a first quick-release component; similarly, the second arc-shaped slot 362 at the end of the second cantilever 36 cooperates with the second fastener 31 and the second rotating shaft 35, the second pivot 33 and the second locking nail 37, so that these components together form a second quick-release component.

[0048] In actual use, when the operator needs to replace the respirator 50, first, the first arc-shaped slot 26 of the first quick-release component is opened relative to the first arc-shaped pressing groove 2324; then, the first arc-shaped slot 26 and the first arc-shaped pressing groove 2324 are jointly clamped on the pipe 60 above the respirator 50, and then the first locking nail 29 is rotated so that its first hooking portion 294 is tightly hooked on a surface of the first fastener 23, thereby allowing the first arc-shaped slot 26 and the first arc-shaped pressing groove 2324 to jointly hold the pipe 60, thereby achieving the first cantilever 24 being fixed on the pipe 60, which means that the entire replacement device 100 is fixed on the pipe 60; then, the operator rotates relative to the cylinder 222 (for example, with the help of a certain auxiliary rotating tool such as The operator then unscrews the bolts on the flange connector between the upper end of the respirator 50 and the pipe 60, so that the respirator 50 is fully supported on the support frame 38; then, the operator allows the second arc-shaped groove 362 and the second arc-shaped pressure groove 316 to be jointly clamped on the upper end of the respirator 50, and then rotates the second locking nail 37 so that its second hooking portion 374 is tightly hooked on a surface of the second fastener 31, thereby allowing the second arc-shaped groove 362 and the second arc-shaped pressure groove 316 to jointly hold the upper end of the respirator 50, and at the same time, the support frame 38 is supported on the bottom of the respirator 50 (reference Figure 3 ); next, the operator can directly flip the flip assembly 30 upside down so as to invert the respirator 50 fixed on the flip assembly 30, and then discharge the waste silica gel particles in the respirator 50; then, flip the flip assembly 30 again to restore the respirator 50 to a normal posture, load new silica gel particles into the respirator, and install related accessories on the respirator 50; finally, fix the respirator 50 on the pipe 60, and remove the replacement tool 100.

[0049] During the above operation, if the respirator 50 cannot be directly flipped over due to the small longitudinal gap between the respirator 50 and the pipe 60, the main shaft 10 can be rotated so that the flipping assembly 30 fixed on the main shaft 10 is rotated horizontally by an angle and rotated to another position with a larger space for flipping operation.

[0050] Therefore, it can be seen from the above structure and operation process that the transformer breather replacement device of the present invention cleverly fixes the fixing component on the pipe in a quick-release manner, and then sets the breather on the flip component through the cooperation of the main shaft that rotates horizontally relative to the fixing component and the flip component arranged at the bottom of the main shaft, and replaces the silica gel particles in the breather by flipping the flip component, so the operation is simple, easy and convenient, which greatly improves the replacement efficiency and reduces the labor intensity.

[0051] Preferably, an external thread (not shown) is formed on the first axial end 12 of the main shaft 10 , and an internal thread (not shown) matching with the external thread is formed in the axial hole 224 of the fixing assembly 20 .

[0052] Preferably, an anti-skid pad (not shown) is provided on the inner side surface of the first arc-shaped slot 26. After the anti-skid pad is provided, the degree of compression between the first arc-shaped slot 26 and the pipe 60 can be further enhanced, thereby preventing the transformer breather replacement device 100 carrying the above-mentioned transformer breather 50 from slipping on the pipe 60. Specifically, the fixing component 20 is prevented from slipping on the pipe 60, thereby improving the reliability of the connection and ensuring the safety of the operation.

[0053] Further preferably, an anti-slip pad (not shown) is also provided on the first arc-shaped pressing groove 2324 that cooperates with the first arc-shaped clamping groove 26, thereby achieving a similar technical effect.

[0054] Preferably, an anti-skid pad (not shown) is provided on the inner side surface of the second arc-shaped slot 362. After the anti-skid pad is provided, the degree of compression between the second arc-shaped slot 362 and the transformer breather 50 can be further enhanced, thereby preventing the transformer breather 50 from slipping up and down relative to the second cantilever 36 of the transformer breather replacement device 100, thereby improving the reliability of the fixed connection between the two and ensuring the operational safety during the replacement of the silica gel particle desiccant in the breather.

[0055] Further preferably, an anti-slip pad (not shown) is also provided on the second arc-shaped pressing groove 316 that cooperates with the second arc-shaped groove 362 , thereby achieving a technical effect similar to that of the second arc-shaped groove 362 .

[0056] Preferably, the transverse axis 34 is arranged in the middle of the longitudinal direction of the longitudinal connecting plate 32, so that when flipping up and down relative to the transverse axis hole 1422, the operator can flip the entire flip assembly 30 and the transformer breather 50 arranged on the flip assembly 30 without any effort.

[0057] Preferably, a bearing 342 is provided on the transverse shaft 34 of the flip assembly 30, and the transverse shaft 34 is rotatably arranged in the transverse shaft hole 1422 by means of the bearing 342. The bearing 342 can further reduce the friction resistance generated when the flip assembly 30 flips, thereby saving more effort when flipping.

[0058] Preferably, the cross-sectional shape of the longitudinal connecting plate 32 is rectangular. Such a longitudinal connecting plate 32 with a rectangular cross-sectional shape makes it easy for an operator to hold the longitudinal connecting plate 32 by hand, thereby facilitating the application of external force to flip the longitudinal connecting plate 32 up and down, thereby improving the convenience of operation.

[0059] Preferably, a reinforcing rib 322 is formed on the longitudinal connecting plate 32 at a position corresponding to the transverse axis 34 , so as to strengthen the structural strength of the entire longitudinal connecting plate 32 and prevent the longitudinal connecting plate 32 from breaking at the position of the transverse axis 34 when the operator flips the longitudinal connecting plate 32 .

[0060] Preferably, a wrench 40 is further included, which has a mounting cylinder 42 fixedly sleeved on the first axial end 12 of the spindle 10 and located above the cylindrical body 222, and a handle 44 radially extending from the circumferential surface of the mounting cylinder 42. By rotating the handle 44 of the wrench 40, the operator can easily rotate the spindle 10 according to the lever principle, thereby achieving axial movement of the spindle 10 relative to the cylindrical body 222.

[0061] Preferably, the support frame 30 is an annular support frame, which is light in weight and allows some components of the transformer breather 50 to extend from the hollow portion of the annular support frame, so that the breather 50 can be easily disassembled, and the discarded silica gel particles can be quickly and conveniently removed and filled with new silica gel particles.

[0062] Preferably, the mounting seat 142 on the second shaft end 14 of the main shaft 10 is configured to be rotatable around the axis of the main shaft 10. In the above operation, if the longitudinal gap between the respirator 50 and the pipe 60 is relatively small and the respirator 50 cannot be directly flipped, the main shaft 10 can be rotated without rotating the flip assembly 30 together with the main shaft 10, that is, the flip assembly 30 and the respirator 50 fixed thereon remain stationary. Since the cylinder 222 cannot move up and down relative to the pipe 60, the rotation action causes the main shaft 10 to move axially up and down relative to the cylinder 222, so that the longitudinal gap between the respirator 50 and the pipe 60 can be widened, and then the respirator 50 can be directly flipped up and down.

[0063] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
