The application of this isolating switch in the power field is of great significance. For example, in areas suffering from severe ice and snow disasters, the double-position ice-melting isolating switch with self-melting function can melt the ice in time, avoid line tripping and equipment damage, and ensure normal electricity use for residents and enterprises.

[0003] The patent application with application number CN202211309953.7 discloses a self-melting double-position isolating switch, including an ice isolating switch, the opening static contact includes an opening static contact rod, the opening static contact rod is fixedly mounted on a supporting base through an insulator, a static contact base is fixedly mounted on the support insulator, and a closing static contact rod is provided on the static contact base.

[0016] Compared with the prior art, the present invention provides a self-melting double-position isolating switch, which has the following features:

[0017] Beneficial effects:

[0018] 1. The present invention is provided with a pushing mechanism. When the pushing arm slides inside the switch box, deicing oil will be sprayed into the interior of the isolation box from both sides of the spray pipe. The deicing oil increases the freezing point of ice inside the isolation box, thereby preventing the interior of the isolation box from freezing due to cold weather, so that the pushing arm can be pushed smoothly inside the isolation box, thereby preventing the moving contact and the static contact inside the switch box from failing to contact and connecting the circuit.

[0019] 2. The present invention is provided with a covering component. By squeezing the stretching tube, the de-icing oil inside the liquid storage tank is subjected to pressure and discharged into the spray plate through the compression ring and sprayed out from the nozzle of the spray block, thereby reducing the melting point of the ice beads on the surface of the moving contact and accelerating the melting of the ice beads. By providing this component, it can be avoided that when the moving contact is connected to the surface of the static contact, the ice beads condensed on the surface of the moving contact affect the connectivity between the circuits.

[0020] 3. The present invention is provided with a pulling mechanism and a stretching tube. The cover plate is pushed away from the surface of the moving contact by extending and retracting the push blocks on both sides outward. The moving contact is brought into contact with the static contact by pulling the push arm on the left. By setting up this mechanism, when the ice melting work on the surface of the moving contact is completed, the cover plate can be automatically popped out without affecting the subsequent related work of the isolating switch connecting the circuit.

[0021] 4. The present invention is provided with an ice-breaking mechanism, which can saw the thin ice on the surface of the static contact through two breaking plates on the surface of the breaking block, so that the contact end of the static contact surface leaks out. At this time, by pulling the pushing arm inward, the moving contact and the static contact can be brought into contact, thereby connecting the circuit. By setting up this mechanism, the ice surface on the static contact surface that has solidified due to cold weather can be sawed, and at the same time, in the subsequent circuit connection work, the connection between the moving contact and the static contact is not affected.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

The right side of the inner wall of the switch box 1 is fixedly connected with the static contact 4. When the moving contact 5 is in close contact with the static contact 4, the current can smoothly pass through the isolating switch to achieve circuit connectivity. At this time, the electrical connection is established, and the electric energy can be transmitted from the power supply end to the output port 2. The moving contact is separated from the static contact to form an obvious electrical gap, thereby cutting off the current path of the circuit and achieving circuit isolation. A lifting mechanism 7 is provided on the left side of the inner wall of the switch box 1. The isolation box 3 located on the right side of the switch box 1 is used to control the lifting mechanism 7. An ice-breaking mechanism 8 is provided on the right side of the inner wall of the switch box 1. The ice-breaking mechanism 8 is provided on the surface of the static contact 4, and also includes:

[0036] The pushing mechanism 6 includes a pushing arm 601 which is slidably connected to the bottom of the inner wall of the isolation box 3, a spray pipe 602 is fixedly connected to the front side of the pushing arm 601, a compression ring 603 is fixedly connected to the front side of the pushing arm 601, an air pressure cavity is opened inside the compression ring 603, when pressed, it will expand and contract inward to generate air pressure and push the moving contact 5 in the switch box 1, one end of the compression ring 603 away from the pushing arm 601 is fixedly connected to the top of the isolation box 3, a stretching tube 605 is slidably connected in the top slot of the pushing arm 601, a pressing ring 604 is fixedly connected to the top of the stretching tube 605, both ends of the pressing ring 604 are fixedly connected to the left and right sides of the pushing arm 601, and a feeding assembly 606 is arranged on the left and right sides of the pushing arm 601.

[0037] The feeding assembly 606 includes a connecting tube 6067 fixedly connected to the left and right sides of the pushing arm 601, an end of the connecting tube 6067 away from the pushing arm 601 is fixedly connected to an output tube 6061, the output tube 6061 is fixedly connected to the inner wall of the pushing arm 601, the inner wall of the output tube 6061 is fixedly connected to a liquid storage tank 6062, and output rods 6063 are fixedly connected to the slots on both sides of the liquid storage tank 6062, and the end of the output rod 6063 away from the liquid storage tank 6062 is fixedly connected to one side of the inner wall of the output tube 6061, and the output The surface of the rod 6063 is slidably connected to a discharge ring 6064, the right side of the discharge ring 6064 is fixedly connected to a guide rod 6065, and the left side of the discharge ring 6064 is fixedly connected to a stretching belt 6066. The stretching belt 6066 has the characteristics of telescopic rebound. When the discharge ring 6064 slides outward to the inner wall of the output pipe 6061, the discharge ring 6064 can be pulled back into the liquid storage tank 6062 through the stretching belt 6066. The end of the stretching belt 6066 away from the discharge ring 6064 is fixedly connected to the left side of the liquid storage tank 6062.

[0038] The working method of the first embodiment is as follows: when the push arm 601 in the isolation box 3 is pushed, the stretch tube 605 is pressed toward the bottom through the pressing ring 604, and the stretch tube 605 is compressed inward after being pressed to generate pressure inside the liquid storage tank 6062, so that the discharge ring 6064 pops outward from the inside of the liquid storage tank 6062. When the discharge ring 6064 pops out, it slides on the surface of the output rod 6063. When the discharge ring 6064 slides outward to the two sides of the inner wall of the output tube 6061, it contacts the absorption holes on the two sides of the inner wall of the output tube 6061 through the guide rod 6065, and generates pressure on the surface of the output tube 6061. The deicing oil in the discharge ring 6064 flows into the connecting pipe 6067 through the output pipe 6061, and the deicing oil in the connecting pipe 6067 flows into the push arm 601. Finally, when the push arm 601 slides inside the switch box 1, the deicing oil is sprayed into the isolation box 3 from both sides of the spray pipe 602. The deicing oil increases the freezing point of the ice inside the isolation box 3 to prevent the inside of the isolation box 3 from freezing due to cold weather, so that the push arm 601 can be pushed smoothly inside the isolation box 3, avoiding the moving contact 5 and the static contact 4 inside the switch box 1 from not being able to contact and connect the circuit.

[0039] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6The lifting mechanism 7 includes a bottom plate 701, which is fixedly connected to the left side of the inner wall of the switch box 1, and the bottom plate 701 is arranged on the outer side of the moving contact 5. The top of the bottom plate 701 is fixedly connected with a compression tube 702, and the top of the compression tube 702 is fixedly connected with a push cavity block 703, and the bottom of the inner wall of the push cavity block 703 is fixedly connected with a lifting arm 704, and one end of the lifting arm 704 away from the inner wall of the push cavity block 703 is fixedly connected with a push block 705, and one end of the push block 705 away from the lifting arm 704 is rotatably connected to both sides of the inner wall of the push cavity block 703 through a rotating shaft, and the inner wall of the bottom plate 701 is provided with a covering component 7 06. The isolation box 3 located on the right side of the switch box 1 is used to control the garbage lifting mechanism 7. When the pressing ring 604 in the isolation box 3 on the right side of the switch box 1 is pushed, the compression ring 603 is squeezed by pushing the pressing ring 604, thereby driving the compression ring 603 to bend inward and discharge the internal air pressure into the switch box 1 through the internal air path 10 of the isolation box 3. The switch box 1 is also provided with an air path 10, which extends from one end of the compression ring 603 through the interior of the switch box 1 into the interior of the contraction chamber 7061, and enters the telescopic belt 7062 through the internal cavity of the contraction chamber 7061.

[0040] The covering assembly 706 includes a shrinkage cavity 7061, both sides of which are fixedly connected to the inner wall of the bottom plate 701, the shrinkage cavity 7061 is fixedly connected to the left side of the inner wall of the switch box 1, a telescopic belt 7062 is slidably connected to the top slot of the shrinkage cavity 7061, and a covering plate 7063 is fixedly connected to the end of the telescopic belt 7062 away from the shrinkage cavity 7061.

[0041] The covering assembly 706 also includes a plug-in arm 7066, one end of which is fixedly connected to the surface of the covering plate 7063, and a friction block is installed on the inner wall of the plug-in arm 7066. The plug-in arm 7066 has the characteristic of telescoping outward. When the plug-in arm 7066 moves to the surface of the moving contact 5, the moving contact 5 and the covering plate 7063 can be fixed by the friction block. Compression bag tubes 7067 are fixedly connected to both sides of the inner wall of the plug-in arm 7066, and a spray plate 7064 is fixedly connected to the bottom of the inner wall of the covering plate 7063, and spray blocks 7065 are fixedly connected to both sides of the spray plate 7064.

[0042] The working method of the second embodiment of the present invention is as follows: the isolation box 3 located on the left side of the switch box 1 is used to control the moving contact, and by pushing the pressing ring 604 and squeezing the compression ring 603, the compression ring 603 is driven to bend inward and discharge the internal air pressure into the switch box 1 through the air path 9 inside the isolation box 3, and the switch box 1 is also provided with an air path 9, which extends from one end of the compression ring 603 into the slot on the left side of the inner wall of the switch box 1. When the air pressure inside the compression ring 603 enters the slot on the left side of the inner wall of the switch box 1 through the air path 9 and pushes the moving contact 5, the moving contact 5 is pushed by the air pressure and pops out from the inside of the switch box 1, and the pressing ring 604 is pulled outward. 04, the compression ring 603 is pulled outward, and the compressed gas inside the switch box 1 is sucked into the interior. At this time, the compressed gas inside the switch box 1 disappears, and the bottom of the moving contact 5 has the characteristic of telescopic reset, so the moving contact 5 will retract inward into the inside of the switch box 1, and the pressing ring 604 inside the isolation box 3 on the right side of the switch box 1 is pulled forward, driving the compression ring 603 to bend outward and discharge the internal air pressure into the switch box 1, and then enters the contraction cavity 7061 through the air path 10 inside the switch box 1, and the air pressure flows from the contraction cavity 7061 into the telescopic belt 7062. The telescopic belt 7062 has a telescopic characteristic and a cavity is opened inside. When the telescopic belt 706 2 will expand and contract outward after receiving the air pressure. Since the moving contact 5 is arranged inside the bottom plate 701, and the contraction cavity 7061 is arranged on the right side of the bottom plate 701, when the expansion belt 7061 expands and contracts outward, the expansion belt 7062 that expands and contracts outward drives the cover plate 7063 to move to the surface of the moving contact 5, and the plug-in arms 7066 on both sides of the cover plate 7063 will be stuck on the surface of the moving contact 5. The two ends of the plug-in arms 7066 fix the cover plate 7063 on the surface of the moving contact 5. By squeezing the stretch tube 605, the ice oil inside the liquid storage tank 6062 will enter the push arm 601 through the connecting pipe 6067, and pass through the internal groove of the push arm 601. The hole is absorbed by the absorption tube inside the compression ring 603. When the compression ring 603 bends outward, the internal air pressure will be discharged into the internal air path 10 of the switch box 1. During the discharge process, the air pressure will push the deicing oil in the absorption tube, so that the deicing oil enters the internal cavity of the contraction chamber 7061 through the internal air path 10 of the switch box 1. The air pressure is then injected into the spray plate 7064 through the internal cavity of the telescopic belt 7062 and sprayed out from the pipe mouth of the spray block 7065, thereby reducing the melting point of the ice beads on the surface of the moving contact 5 and accelerating the melting of the ice beads. This can prevent the moving contact 5 from being connected to the surface of the static contact 4 due to the ice beads condensed on the surface of the moving contact 5 affecting the connectivity between the circuits.

[0043] Example 3: Based on Example 2, continue to refer to Figure 7-Figure 8The ice-breaking mechanism 8 includes a pressure cover box 801, which is fixedly connected to the surface of the static contact 4. A pulling ring 802 is rotatably connected to the top slot of the inner wall of the pressure cover box 801 through a rotating shaft, and a breaking assembly 803 is arranged at one end of the pulling ring 802.

[0044] The crushing assembly 803 includes a contact plate 8031, which is fixedly connected to one end of the pulling ring 802, a squeezing bag 8032 is fixedly connected to the left side of the contact plate 8031, and a suction clamp 8033 is fixedly connected to the right side of the contact plate 8031. Both ends of the suction clamp 8033 are smeared with sticky substances. When the contact plate 8031 ​​moves to the inner wall of the static contact 4, the contact plate 8031 ​​will be adsorbed on the inner wall of the static contact 4 by the suction clamp 8033. A crushing block 8034 is slidably connected to the groove hole on the inner wall of the pressure cover box 801, and a crushing plate is installed on the inner wall of the crushing block 8034. When the crushing block 8034 is retracted inwardly, the thin ice on the surface of the static contact 4 can be sawed by the crushing plate. The end of the crushing block 8034 away from the pressure cover box 801 is plugged into the surface groove hole of the contact plate 8031.

[0045] The working method of the third embodiment is as follows: when the cover plate 7063 is pushed outward by the push block 705, the popped-up cover plate 7063 will move to the surface of the contact plate 8031, and the back of the cover plate 7063 will face the surface of the extrusion bag 8032. Since the crushing block 8034 has the characteristics of telescopic reset, when the crushing block 8034 is under pressure, it will be retracted into the interior of the pressure cover box 801. During the retraction process, since the inner wall of the crushing block 8034 is slidably connected to two crushing plates, when the extrusion bag 8032 is squeezed by the cover plate 7063, the air pressure inside the extrusion bag 8032 will be sprayed into the interior of the contact plate 8031, and the air pressure will push the crushing plate 8034. At the same time, the air pressure will cause the two crushing plates inside the crushing block 8034 to pop outward. When the crushing plate 8034 is extended and retracted outward, the thin ice on the surface of the static contact 4 is sawed by the two pop-up crushing plates, so that the contact end of the surface of the static contact 4 leaks out, and after the contact plate 8031 ​​is pushed by the covering plate 7063, it will rotate on the inner wall of the pressure cover box 801 through the pulling ring 802 and swing outward. When the contact plate 8031 ​​is swung to the inner wall of the static contact 4, the contact plate 8031 ​​can be fixed to the inner wall of the static contact 4 by two adsorption clamps 8033. At this time, by pulling the pushing arm 601 inward, the moving contact 5 can be brought into contact with the static contact 4, thereby connecting the circuit. The ice surface on the surface of the static contact 4 that is frozen due to the cold weather can be sawed. At the same time, in the subsequent circuit connection work, the connection between the moving contact 5 and the static contact 4 is not affected.
