Description

Technical Field

[0001] The invention relates to the technical field of respirator auxiliary tools, and in particular to a new tool for replacing a respirator under power in a substation. Background Art

[0002] Transformers and capacitors are key components of substations. Oil-immersed transformers and oil-immersed collective capacitors have a common component, the oil pillow breather. The breather regulates the internal pressure of the transformer and filters the air entering the transformer. It is an indispensable component for maintaining the normal operation of transformers and capacitors. And precisely because of this function, it is often necessary to replace the damp silicone and transformer oil in the oil cup. However, in many cases, the breather is very close to the oil pillow and the safe distance from the live parts is insufficient. For example, the oil pillow breather of the transformer on-load tap changer and the capacitor with a safety fence are currently replaced by power outage. The power outage lasts for one or two hours and the replacement takes half an hour. This not only wastes a lot of human resources, but also causes the equipment to be affected by the power outage, which greatly affects the reliability of power supply. Summary of the invention

[0038] Example 1

[0039] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, provides a new type of tool for replacing a respirator under power in a substation, the device comprising:

[0040] The support mechanism 100 includes a first insulating rod 101, a first handle 102 fixedly connected to the bottom end of the first insulating rod 101, and a first mounting plate 103 mounted on the top end of the first insulating rod 101 by bolts, a connecting component 104 is arranged inside the first mounting plate 103, and a placing component 105 is adapted to be mounted on one end of the connecting component 104;

[0041] The driving mechanism 200 includes a second insulating rod 201, a second handle 202 fixedly connected to the bottom end of the second insulating rod 201, and a second mounting plate 203 installed on the top end of the second insulating rod 201 by bolts. A control switch 204 is provided on the outside of the second handle 202, and a power component 205 is provided inside the second mounting plate 203.

[0042] Specifically, the placement component 105 includes a connecting rod 105a, a lower card frame 105b fixedly connected to the bottom end of the connecting rod 105a, and an upper card frame 105c fixedly connected to the top end of the connecting rod 105a, a connecting column 105d is provided between the upper card frame 105c and the lower card frame 105b, and a side plate 105e is fixedly connected to the outer side of the upper card frame 105c;

[0043] The side plate 105e is installed on the top of the connecting rod 104a by bolts, and the lower bracket 105b, the upper bracket 105c and the connecting rod 105a are made of rubber.

[0044] Further, the power component 205 includes a long rod 205a installed on the inner side of the second mounting plate 203 by bolts, a mounting block 205b installed on the outer side of the long rod 205a by bolts, and a sleeve 205c arranged inside the mounting block 205b;

[0045] A motor is disposed inside the mounting block 205 b , an output end of the motor is connected to the sleeve 205 c , and the motor is electrically connected to the control switch 204 .

[0046] When in use, the staff first holds the first handle 102 and clamps the lower clamp frame 105b and the upper clamp frame 105c on the outside of the respirator. At this time, the staff holds the second handle 202 with the other hand and causes the sleeve 205c to be engaged with the bolts that fix the respirator. Then, the control switch 204 is pressed, which controls the motor to drive the sleeve 205c to rotate to tighten and loosen the bolts, and finally replaces the damp silicone in the respirator and the transformer oil in the oil cup.

[0047] The first insulating rod 101 and the second insulating rod 201 can protect personnel from being away from the power source, and avoid unnecessary danger caused by conduction.

[0048] In summary, by adopting this equipment, the respirator can be replaced while powered on, avoiding equipment downtime and ensuring power supply reliability. At the same time, a series of operations caused by equipment downtime are avoided, saving human resources; and the safety of the staff can be guaranteed.

[0049] Example 2

[0050] Reference Figures 1 to 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a disc 103 a is fixedly connected to the outer side of the first mounting plate 103 , and a slot 103 b is provided at one end of the disc 103 a close to the first mounting plate 103 .

[0051] Furthermore, the connecting component 104 includes a connecting rod 104a, a circular cavity 104b opened inside the connecting rod 104a, and a rotating shaft 104c fixedly connected to the inside of the connecting rod 104a, a limiting assembly 104d is arranged inside the rotating shaft 104c, a trigger assembly 104e is arranged inside the connecting rod 104a, and the rotating shaft 104c is rotatably connected to the first mounting plate 103.

[0052] Furthermore, the limiting assembly 104d includes a first spring 104d-1 fixedly connected to the inside of the rotating shaft 104c, a chassis 104d-2 fixedly connected to the other end of the first spring 104d-1, and a columnar block 104d-3 fixedly connected to one end of the chassis 104d-2 close to the first spring 104d-1, one end of the columnar block 104d-3 is fixedly connected with a clamping block 104d-4, and the clamping block 104d-4 is slidably connected to the rotating shaft 104c.

[0053] Specifically, the trigger assembly 104e includes a trigger rod 104e-1 slidably connected to the inside of the connecting rod 104a, an operating block 104e-2 fixedly connected to one end of the trigger rod 104e-1, and a first groove 104e-3 opened on the outside of the trigger rod 104e-1, a second groove 104e-4 is opened on the outside of the trigger rod 104e-1, a second spring 104e-5 is sleeved on the outside of the trigger rod 104e-1, and an extrusion piece 104e-6 is arranged on the outside of the trigger rod 104e-1;

[0054] The second spring 104e-5 is disposed inside the circular cavity 104b, the second spring 104e-5 is located between the extrusion piece 104e-6 and the circular cavity 104b, and the first groove 104e-3 and the second groove 104e-4 are staggered and opened outside the trigger rod 104e-1.

[0055] Preferably, the extrusion member 104e-6 includes an outer disk 104e-6a fixedly connected to the outer side of the trigger rod 104e-1, and a protrusion 104e-6b fixedly connected to the outer side of the outer disk 104e-6a.

[0056] By rotating the connecting rod 104a, the connecting rod 104a will be rotated on the inner side of the first mounting plate 103 through the rotating shaft 104c. During the rotation of the rotating shaft 104c, the block 104d-4 at one end of the columnar block 104d-3 will be continuously reciprocated and retracted under the design of the rotating force and the first spring 104d-1, until the connecting rod 104a is rotated to a specified angle. At this time, the block 104d-4 will be driven to engage with the card slot 103b under the elasticity of the first spring 104d-1, so as to achieve the initial limit of the connecting rod 104a. With the design of the angle adjustment and initial limit of the connecting rod 104a, the device can be used in various scenarios, thereby improving the overall applicability of the device.

[0057] After the lower bracket 105b and the upper bracket 105c are connected and supported on the respirator, the trigger rod 104e-1 will be completely squeezed into the inside of the connecting rod 104a. At this time, the trigger rod 104e-1 will drive the outer plate 104e-6a to squeeze the second spring 104e-5, and will also cause the first groove 104e-3 on the outer side of the trigger rod 104e-1 to slide away from one end of the chassis 104d-2. At this time, the outer wall of the trigger rod 104e-1 is close to the chassis 104d-2, and the chassis 104d-2 cannot move, so that the block 104d-4 is completely connected to the slot 103b, so that the block 104d-4 cannot move, and finally it can ensure that the connecting rod 104a cannot be adjusted in angle. After the device is connected to the respirator, the device automatically locks the connecting rod 104a.

[0058] In summary, the connecting rod 104a in the design has the functions of adjustable angle and preliminary positioning, which enables the device to adapt to a variety of application scenarios, thereby enhancing its wide applicability. Once the device and the respirator are connected, the connecting rod 104a is automatically locked. This mechanism ensures the stability of the device during the removal and installation of the bolts, thereby ensuring the smooth progress of the operation.

[0059] Example 3

[0060] Reference Fig.10 , Fig.11, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a slide groove 104b-1 is opened on the inner wall of the circular cavity 104b, a front guide groove 104b-2 is opened on the inner wall of the circular cavity 104b, and two front guide grooves 104b-3 are opened on the inner wall of the circular cavity 104b. A transition groove 104b-4 is opened on the inner wall of the circular cavity 104b, a rear guide groove 104b-5 is opened on the inner wall of the circular cavity 104b, and two rear guide grooves 104b-6 are opened on the inner wall of the circular cavity 104b.

[0061] Furthermore, the front guide groove 104b-2 is connected to the rear guide groove 104b-5 through the transition groove 104b-4, the front two guide grooves 104b-3 are connected to the rear two guide grooves 104b-6 through the transition groove 104b-4, and the front guide groove 104b-2 and the front two guide grooves 104b-3 are designed to be parallel to the rear guide groove 104b-5 and the rear two guide grooves 104b-6 respectively.

[0062] After the device is connected to the respirator, one end of the trigger rod 104e-1 is completely located in the connecting rod 104a. At this time, rotating the operating block 104e-2 will drive the protrusion 104e-6b on the outside of the outer disk 104e-6a to rotate along the previous guide groove 104b-2 and the first two guide grooves 104b-3 until it cannot rotate and stops. After the outer disk 104e-6a cannot rotate, it will drive the trigger rod 104e-1 to rotate ninety degrees, thereby rotating the second groove 104e-4 on the outside of the trigger rod 104e-1 to one end of the chassis 104d-2. At this time, the chassis 104d-2 can be moved, and the angle of the connecting rod 104a can be adjusted. After the adjustment is completed, the reverse control operating block 104e-2 can self-lock the connecting rod 104a again.

[0063] When the device is connected to the respirator, if the angle of the connecting rod 104a still needs to be adjusted, the angle of the connecting rod 104a can be adjusted by rotating the operating block 104e-2 ninety degrees and moving the operating block 104e-2 up and down.

[0064] After the rotating operating block 104e-2 drives the protrusion 104e-6b on the outside of the outer disk 104e-6a to rotate ninety degrees, the operating block 104e-2 can continue to be pulled, and the protrusion 104e-6b will slide to the inside of the rear guide groove 104b-5 and the rear second guide groove 104b-6 under the guidance of the transition groove 104b-4. Then, the operating block 104e-2 is reversed ninety degrees to drive the protrusion 104e-6b to be completely located in the rear guide groove 104b-5 and the rear second guide groove 104b-6. At this time, under the elasticity of the first spring 104d-1, it can be ensured that the protrusion 104e-6b is always located in the rear guide groove 104b-5 and the rear second guide groove 104b-6. At this time, even if the respirator is taken out from the lower bracket 105b and the upper bracket 105c, the connecting rod 104a cannot be adjusted because the outer wall of the trigger rod 104e-1 is always in contact with the chassis 104d-2, further improving the applicability of the equipment.

[0065] After the operation block 104e-2 is rotated to drive the protrusion 104e-6b on the outer side of the outer disk 104e-6a to rotate 90 degrees, the operation block 104e-2 can be directly released, and the elasticity of the first spring 104d-1 can ensure that the protrusion 104e-6b is always located in the first guide groove 104b-2 and the second guide groove 104b-3. At this time, even if the respirator is clamped in the lower clamping frame 105b and the upper clamping frame 105c, the angle of the connecting rod 104a can still be adjusted, further improving the applicability of the device.

[0066] In summary, with this device, the respirator can be replaced without power outage, which not only avoids the loss caused by equipment downtime, but also ensures the continuity and reliability of power supply. At the same time, it also provides a safe working environment for the staff. The connecting rod 104a in the device is designed with angle adjustment and preliminary positioning functions. This feature allows the device to flexibly adapt to a variety of different usage scenarios, significantly improving its wide application.

[0067] When the device is connected to the respirator, the connecting rod 104a will automatically lock. This design ensures the stability of the device during the removal and installation of the bolts and ensures the smoothness of the operation process. In addition, through the adjustment of the operating block 104e-2, the device can achieve a variety of different states to meet the specific needs of different scenarios, further improving the adaptability and flexibility of the device.
