[0002] With the development of distribution network technology, the scale of urban distribution network is getting larger and larger, and the structure is becoming more and more complex. At present, the 10kV urban distribution network is composed of overhead line-cable grid. When the substation is renovated or the outgoing cable fails, the live removal or splicing of the cable terminal lead is usually adopted, which can meet the distribution network maintenance requirements without affecting the user's power demand, and can effectively improve the reliability of power supply.

[0003] Live disconnection of unloaded cable lines and overhead line connection leads belongs to the third category of complex live work projects. Unloaded cables have capacitive characteristics, and arcs will be generated when live connection of terminal leads is performed.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0039] The embodiment of the first aspect of the present invention is to provide an arc extinguishing switch opening and closing tool, such as Figures 1 to 3As shown, it includes a first support 1, a first driver 2 and a push block 3. The first support 1 has a limit surface 111 for limiting the downward movement of the main body 41 of the arc extinguishing switch 4 relative to the first support 1 in the vertical direction. The fixed end of the first driver 2 is installed on the first support 1, and the movable end of the first driver 2 is connected to the push block 3. The first driver 2 is used to drive the push block 3 to press down any one of the pull rod 42 and the trigger 43 of the arc extinguishing switch 4 once.

[0040] When using the above-mentioned arc extinguishing switch separation and closing tool, the first support 1 and the push block 3 can be aligned with the pull rod 42 of the arc extinguishing switch, and the limit surface 111 of the first support 1 can be matched with the main body 41 of the arc extinguishing switch to limit the downward movement of the main body 41 relative to the first support 1 in the vertical direction. Since the vertical position of the main body 41 relative to the first support 1 is fixed, the movable end of the first driver 2 can drive the push block 3 to selectively press down the pull rod 42 and the trigger 43 of the arc extinguishing switch, thereby realizing the downward pressing and resetting of the pull rod 42.

[0041] Compared with the prior art, the arc extinguishing switch opening and closing tool provided in the embodiment of the first aspect of the present invention can replace the operator in pressing down the pull rod 42 and the trigger 43, thereby reducing the labor intensity of the operator, improving work efficiency, and ensuring the safety of the operator.

[0042] The structure of the first support 1 is described in detail below:

[0043] In an optional embodiment, if Figure 1 and Figure 2 As shown, the first support 1 has a limit end, and the limit end has a sinking platform 11 which is recessed from top to bottom along the vertical direction. The bottom surface of the sinking platform 11 is a limit surface 111. The limit end also has a first plug-in groove 12 for the pull rod 42 to be inserted into the limit end. The first plug-in groove 12 is located below the sinking platform 11 and is connected to the sinking platform 11.

[0044] When in use, the first plug-in slot 12 can approach the pull rod 42 of the arc extinguishing switch 4 in the horizontal direction, so that the pull rod 42 enters the first plug-in slot 12 until the pull rod 42 is abutted against the inner end of the first plug-in slot 12. Since the first plug-in slot 12 is located below the sinking platform 11 and is connected to the sinking platform 11, the pull rod 42 also enters the space surrounded by the sinking platform 11 at this time; then the first support 1 is moved upward so that the limit surface 111 is abutted against the lower end surface of the main body 41; then the first driver 2 drives the push block 3 to move, and the push block 3 presses down the pull rod 42 or the trigger 43.

[0045] The above-mentioned limiting end can limit the main body 41 to move downward relative to the first support 1 in the vertical direction, ensuring that the push block 3 can smoothly press the pull rod 42 or the trigger 43 downward.

[0046] It should be noted that the inner end of the first plug-in through slot 12 refers to an end of the first plug-in through slot 12 that is away from its opening for the pull rod 42 to enter in the horizontal direction.

[0047] In an optional embodiment, the sink 11 may have a side arc surface that is adapted to the shape of the outer circumferential surface of the main body 41. When the pull rod 42 abuts against the inner end of the first plug-in groove 12, it synchronously abuts against the outer circumferential surface of the main body 41, thereby providing lateral support and limiting the arc extinguishing switch 4.

[0048] In an optional embodiment, if Figure 1 As shown, the first plug-in groove 12 includes a guide groove 121 and a limiting groove 122 located below the sink 11 and connected to the sink 11. The shape of the groove wall at the inner end of the limiting groove 122 is used to adapt to the outer peripheral surface of the pull rod 42. The outer end of the limiting groove 122 is connected to the guide groove 121, and the opening formed by the groove wall of the guide groove 121 gradually increases in the direction gradually away from the limiting groove 122.

[0049] It can be understood that the outer end is an end of the limiting groove 122 having an opening to allow the pull rod 42 to enter, and the inner end is an end of the limiting groove 122 that is away from the opening in the horizontal direction.

[0050] In the above embodiment, the opening formed by the groove wall of the guide groove 121 gradually increases in the direction gradually away from the limiting groove 122, which makes it easier for the pull rod 42 to enter the first plug-in groove 12. When the pull rod 42 is inserted into the limiting end, there is no need for a high position accuracy between the pull rod 42 and the limiting end. The guide groove 121 can guide the pull rod 42 to the limiting groove 122 until the pull rod 42 is against the groove wall at the inner end of the limiting groove 122.

[0051] Specifically, the V-shaped opening angle formed by the groove wall of the guide groove 121 may be 60°.

[0052] The structure of the push block 3 is specifically described below:

[0053] In an optional embodiment, if Figure 2 and Figure 3 As shown, the push block 3 has a first pressing portion 31 located below the first support 1, the first pressing portion 31 has a second insertion groove 311 for the pull rod 42 to extend into, and the bottom surface of the first pressing portion 31 facing away from the first support 1 is a first pressing surface 312 for pressing down the pull rod 42.

[0054] When in use, when the pull rod 42 abuts against the inner end of the first plug-in slot 12, the pull rod 42 synchronously enters the second plug-in slot 311 and abuts against the inner end of the second plug-in slot 311; then the first support 1 is moved upward so that the limiting surface 111 abuts against the lower end surface of the main body 41; then the first driver 2 drives the push block 3 to move downward, and the first pressing surface 312 on the first pressing portion 31 contacts the end plate 421 at the bottom end of the pull rod 42 and presses down the end plate 421, thereby pressing the pull rod 42 downward.

[0055] In an optional embodiment, if Figure 2 and Figure 3 As shown, the push block 3 also has a second pressing portion 32 connected to the first pressing portion 31 , the top of the second pressing portion 32 is higher than the limiting surface 111 , and the top of the second pressing portion 32 has a second pressing surface 321 for pressing down the trigger 43 .

[0056] When in use, when the pull rod 42 abuts against the inner end of the first plug-in slot 12, the pull rod 42 simultaneously enters the second plug-in slot 311 and abuts against the inner end of the second plug-in slot 311, and at the same time, the second pressing portion 32 is located directly above the trigger 43; then the first support 1 is moved upward so that the limiting surface 111 abuts against the lower end surface of the main body 41; then the first driver 2 drives the push block 3 to move downward, and the second downward pressing surface 321 on the second pressing portion 32 presses down the trigger 43, thereby resetting the pull rod 42.

[0057] In the above embodiment, the top of the second pressing portion 32 is higher than the limiting surface 111 , which makes it easier for the second pressing portion 32 to extend to the top of the trigger 43 when the pull rod 42 is inserted into the limiting end.

[0058] In an optional embodiment, the first pressing portion 31 and the second pressing portion 32 are of an integrated structure.

[0059] The structure of the first driver 2 is described in detail below:

[0060] It should be noted that any structure that can drive the push block 3 to move back and forth along a straight line can be the first driver 2 mentioned in the above embodiment. For example, the first driver is a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc.

[0061] In a preferred embodiment, the first drive 2 is a linear push rod electric cylinder.

[0062] The linear push rod electric cylinder can be equipped with a distance sensor and a pressure sensor. When the linear push rod electric cylinder drives the push block 3 to move downward, the linear push rod electric cylinder stops driving until the distance sensor detects that the distance position is in place and the pressure sensor detects that the thrust reaches the set value, completing the extension of the arc extinguishing switch 4 pull rod or the resetting of the pull rod.

[0063] The cylinder of the first driver 2 can be fixedly connected to the first support 1 and move up and down with the first support 1 . The push rod of the first driver 2 is connected to the push block 3 , driving the push block 3 to move up and down relative to the first support 1 .

[0064] In an optional embodiment, if Figures 1 to 3 As shown, the arc-extinguishing switch opening and closing tool also includes a second support 5 and a blocking mechanism 6. The bottom end of the second support 5 has a connecting seat 51 for detachably connecting to the mechanical arm. The second support 5 and the first support 1 are slidably matched in the vertical direction. The blocking mechanism 6 is installed on the second support 5. The blocking mechanism 6 has a blocking state of blocking the first support 1 to the bottom of the sliding stroke and a release state of canceling the blocking of the first support 1.

[0065] When in use, taking the downward pressing rod 42 as an example, the first support 1 and the push block 3 are aligned with the part of the rod 42 located above the end plate 421; then the blocking mechanism 6 blocks the first support 1 to the bottom of the sliding stroke; the robotic arm drives the second support 5 to move upward, so that the limiting surface 111 is against the lower end surface of the main body 41; then the blocking mechanism 6 cancels the blocking of the first support 1; finally, the first driver 2 can drive the push block 3 to press the end plate 421 on the rod 42 downward.

[0066] In the above process, since the second support 5 and the first support 1 slide in cooperation in the vertical direction, in the process of the push block 3 continuously pressing the end plate 421 downward, under the reaction force of the end plate 421, the fixed end of the first driver 2 is forced to drive the first support 1 to move upward relative to the second support 5, and the first support 1 drives the main body 41 of the arc extinguishing switch 4 to move upward, and the main body 41 and the pull rod 42 are relatively displaced. During the upward movement of the main body 41, the cable 9 is lifted; after reaching a certain position, the cable 9 is straightened and no longer displaced, and the main body 41 is fixed, and then the push block 3 drives the end plate 421 to move downward continuously under the drive of the first driver 2 until it is in place. Therefore, in the whole process, the driving force of the first driver 2 is transmitted to the cable 9, and rarely to the mechanical arm below, avoiding the large load force acting on the mechanical arm, and protecting the mechanical arm.

[0067] In an optional embodiment, if Figure 1 As shown, the blocking mechanism 6 includes an electric cylinder 61 and a blocking head 62 connected to the electric cylinder 61. A protrusion 14 is provided on the first support 1. When the electric cylinder 61 drives the blocking head 62 to extend and is located above the protrusion 14, the blocking mechanism 6 is in a blocking state. When the electric cylinder 61 drives the blocking head 62 to retract and cancel the blocking of the protrusion 14, the blocking mechanism 6 is in a released state.

[0068] In an optional embodiment, the side of the first support 1 is slidably matched with the side of the second support 5, and one of the second support 5 and the first support 1 is provided with a slide rail 52 extending in the vertical direction, and the other is provided with a slider 13 slidably matched with the slide rail 52.

[0069] by Figure 1 For example, the second support 5 is provided with a slide rail 52 extending in the vertical direction, and the first support 1 is provided with a slider 13 slidably matched with the slide rail 52 .

[0070] In an optional embodiment, if Figure 2 As shown, the arc-extinguishing switch opening and closing tool also includes a visual positioning system 8, which may include a visual camera. The robotic arm can perform visual positioning of the working position through the visual camera, thereby ensuring that the robotic arm drives the second support 5 to move to a suitable position.

[0071] In an optional embodiment, if Figure 3 and Figure 4 As shown, the arc-extinguishing switch opening and closing tool also includes a housing assembly 7, which at least covers the outside of the first driver 2, the second support 5 and the blocking mechanism 6, and the visual positioning system 8 is connected to the first support 1 or the housing assembly 7.

[0072] The housing assembly 7 mainly protects the various supports, drivers and other structures. Figure 3 and Figure 4 As shown, the housing assembly 7 may specifically include a first housing 71 and a second housing 72. The first housing 71 is disposed on the outside of the second support 5 and the electric cylinder 61, and the second housing 72 is disposed on the outside of part of the first support 1 and part of the first driver 2. The first housing 71 and the second housing 72 are internally connected.

[0073] In an optional embodiment, if Figure 1 As shown, the arc extinguishing switch opening and closing tool also includes a battery electronic control component 10 installed on the second support 5.

[0074] The second aspect of the present invention provides an arc extinguishing device, such as Figure 5 As shown, the arc extinguishing device provided by the embodiment of the second aspect of the present invention includes an arc extinguishing switch 4 and the above-mentioned arc extinguishing switch separation and closing tool. The arc extinguishing switch 4 includes a main body 41, a pull rod 42 and a trigger 43. The pull rod 42 slides with the main body 41 in the vertical direction. The bottom end of the pull rod 42 has an end plate 421. The trigger 43 is connected to the main body 41, and the trigger 43 is hook-shaped.

[0075] When the arc extinguishing switch 4 is in use, the head cable clamp of the main body 41 is connected to the fixed cable 9, and the cable 9 itself floats up and down for a certain distance, so the arc extinguishing switch as a whole floats up and down with the cable 9 for a certain distance, and the end plate 421 is pushed downward to a certain distance by external force, and the pull rod 42 part will be pulled out of the main body 41 and maintain the current position. When the main body 41 is to return to the initial state, an external force is required to trigger the trigger 43 downward, and then the pull rod 42 will automatically retract into the main body 41.

[0076] Compared with the prior art, the arc extinguishing device provided in the embodiment of the second aspect of the present invention includes an arc extinguishing switch and the above-mentioned separation and closing tool. The bottom end of the pull rod 42 in the arc extinguishing switch 4 has an end plate 421, and the trigger 43 is hook-shaped, which makes it easier for the push block 3 to align and press down the pull rod 42 and the trigger 43.

[0077] The embodiment of the third aspect of the present invention is to provide an arc extinguishing method. The arc extinguishing method provided by the embodiment of the third aspect of the present invention adopts the above-mentioned arc extinguishing device, including:

[0078] Steps for pressing the pull rod downward: align the first support 1 and the push block 3 with the part of the pull rod 42 located above the end plate 421; the blocking mechanism 6 blocks the first support 1 to the bottom of the sliding stroke; the mechanical arm drives the second support 5 to move upward so that the limiting surface 111 abuts against the lower end surface of the main body 41; the blocking mechanism 6 cancels the blocking of the first support 1; the first driver 2 drives the push block 3 to press the pull rod 42 downward;

[0079] Steps for pressing the trigger: align the first support 1 with the portion of the pull rod 42 located above the end plate 421, and align the push block 3 with the portion of the pull rod 42 located above the end plate 421 and the trigger 43; the blocking mechanism 6 blocks the first support 1 to the bottom of the sliding stroke; the robotic arm drives the second support 5 to move upward, so that the limiting surface 111 abuts against the lower end surface of the main body 41; the blocking mechanism 6 cancels the blocking of the first support 1; the first driver 2 drives the push block 3 to press the trigger 43 downward.

[0080] The following is based on Figure 6 and Figure 7 The step of pressing the pull rod 42 is described in detail:

[0081] 1. The robot arm performs visual positioning of the working position through the visual positioning system 8, and the working position is the part of the pull rod 42 located above the end plate 421;

[0082] 2. At this time, the blocking mechanism 6 is in a blocking state, blocking the first support 1 and limiting its upward movement;

[0083] 3. Under the guidance of the visual positioning system 8, the part of the pull rod 42 located above the end plate 421 is inserted into the limiting groove 122 by relying on the guide groove 121 of the limiting end, and then the part of the pull rod 42 located above the end plate 421 is synchronously inserted into the second plug-in through groove 311, and the robot arm drives the tool to move as a whole so that the lower end surface of the main body 41 abuts against the limiting surface 111;

[0084] 4. Adjust the blocking mechanism 6 to the released state;

[0085] 5. The first driver 2 drives the first pressing part 31 to continuously press the end plate 421 downward; until the distance sensor detects that the distance position is in place and the pressure sensor detects that the thrust reaches the set value, the linear push rod electric cylinder stops driving, and the arc extinguishing switch 4 pull rod is extended or reset.

[0086] After the work is completed, the first driver 2 drives the push block 3 to reset, and the blocking mechanism 6 resets to limit the vertical movement of the first support 1.

[0087] The following is based on Figure 8 and Fig. 9 The steps of pressing the trigger 43 are described as follows:

[0088] The step of pressing down the trigger 43 is different from the step of pressing down the pull rod 42 in that the operation position is the part of the pull rod 42 located above the end plate 421 and above the trigger 43. Specifically, when the first driver 2 drives the push block 3 to move downward, the second pressing portion 32 presses the trigger 43 downward to complete the triggering of the trigger 43, so that the pull rod 42 automatically rebounds and retracts.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
