Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a pole-mounted fuse state detection and maintenance device. Background Art

[0002] A drop-out fuse is an overcurrent protection device that is connected in series in the protected circuit. When the current exceeds the specified value, the heat generated by the fuse itself will melt the fuse element, and the fuse will fall under the action of gravity, thereby disconnecting the circuit and playing a protective role. A large number of fuses are installed in the substation distribution network scenario. It is time-consuming and laborious to confirm the status of the fuse on site, and it is impossible to quickly and accurately find its location. In order to monitor the device, a set of status detection devices is required to monitor its status. Most of the existing fuse sensors need to be used before the drop-out sensor is installed or wait until the equipment is powered off before the relevant fuse sensors can be fixed on the fuse tube of the fuse. In addition, the fuse sensor cannot be disassembled and maintained when the fuse is in operation, which makes the operation troublesome. Utility Model Content

[0003] The main purpose of the utility model is to provide a pole-mounted fuse state detection and maintenance device to solve the problem of inconvenient disassembly of the fuse sensor in the prior art.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a pole-mounted fuse state detection and maintenance device, including a detection mechanism and an installation mechanism that can freely remove the detection mechanism, wherein the detection mechanism includes a plurality of clamping members, locking members, resetting members and state detection members, the clamping members together form a clamping area for clamping the pole-mounted fuse, the locking member has a locking state abutting against the clamping member, when the locking member is in the locked state, the locking member keeps the clamping area in an open state and at least a part of the locking member is located in the clamping area, the resetting member is connected to the clamping member and provides a resetting force for the clamping member to move to a closed state of the clamping area; the installation mechanism includes a base and an insulating member, the base is connected to the insulating member, the base and the detection mechanism can be docked and matched, and the detection mechanism is transported to the pole-mounted fuse.

[0005] Furthermore, the clamping member has a boss, and the locking member has a slide groove, the slide groove includes a first section and a second section that are bent and connected, the boss is located in the slide groove and can move in the slide groove, and the clamping member can be opened or closed when the boss is located in the first section; when the boss is located in the second section, the boss abuts against the side wall of the second section and hinders the movement of the clamping members approaching each other, and the locking member is in a locked state.

[0006] Furthermore, the second section has a free end and a connecting end connected to the first section, and the direction from the connecting end to the free end forms an angle less than 90 degrees with the direction in which the column fuse extends into the clamping area. When the column fuse extends into the clamping area, it pushes the locking piece to move and causes the protruding column to move from the second section to the first section.

[0007] Furthermore, the clamping members are rotatably arranged in pairs. Among the two clamping members arranged in a pair, one clamping member has a protruding column, and the other clamping member has a connecting column. The locking member has a mounting hole, and the connecting column is passed through the mounting hole so that the locking member can be rotatably connected to the clamping member with the connecting column.

[0008] Furthermore, the clamping member also has a sliding groove, and the detection mechanism also includes an unlocking member, which is inserted into the sliding groove, and the reset member is connected to the unlocking member. When the unlocking member moves in the sliding groove, it controls the tensioning and relaxation of the reset member.

[0009] Furthermore, the sliding groove includes a first sliding section and a second sliding section which are bent and connected. When the unlocking member is located in the first sliding section and moves, the reset member can be relaxed.

At the same time, the locking member of the detection mechanism The reset part enables the detection mechanism to have not only a clamping state but also an open state, so that the detection mechanism can not only be installed on the pole fuse but also be removed from the pole fuse. The other part is the installation mechanism, which can dock and cooperate with the detection mechanism to transport the detection mechanism to the pole fuse or remove it from the pole fuse, so that when the pole fuse is in working state, the status detection part can also be freely disassembled and assembled. In this way, when the status detection part is abnormal, the status detection part can be removed from the pole fuse using the installation mechanism, and the replacement and maintenance functions can be easily realized.

DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0032] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0033] In order to solve the problem of inconvenient disassembly of the fuse sensor in the prior art, the utility model provides a pole-mounted fuse state detection and maintenance device.

[0034] like Figures 1 to 12A pole-mounted fuse state detection and maintenance device shown in the figure includes a detection mechanism 10 and an installation mechanism 20 that can freely remove the detection mechanism 10, wherein the detection mechanism 10 includes a plurality of clamping members 11, a locking member 12, a reset member 13 and a state detection member 15, the clamping members 11 together form a clamping area for clamping the pole-mounted fuse, the locking member 12 has a locking state abutting against the clamping member 11, when the locking member 12 is in the locked state, the locking member 12 keeps the clamping area in an open state and at least a part of the locking member 12 is located in the clamping area, the reset member 13 is connected to the clamping member 11 and provides a reset force for the clamping member 11 to move to a closed state of the clamping area; the installation mechanism 20 includes a base 21 and an insulating member 22, the base 21 is connected to the insulating member 22, the base 21 and the detection mechanism 10 can be docked and matched, and the detection mechanism 10 is transported to the pole-mounted fuse.

[0035] In this embodiment, the state detection member 15 can be freely disassembled and replaced in the running state of the power equipment through the cooperation of the detection mechanism 10 and the installation mechanism 20. Specifically, the pole-mounted fuse state detection and maintenance device includes two parts, one of which is the detection mechanism 10. The detection mechanism 10 has a clamping area, and the clamping area cooperates with the pole-mounted fuse, so that the detection mechanism 10 can be installed on the pole-mounted fuse and automatically clamped, so as to monitor the state of the pole-mounted fuse. When the pole-mounted fuse fails, it can be handled in time to avoid accidents. Therefore, losses are caused. At the same time, the locking member 12 and the reset member 13 of the detection mechanism 10 enable the detection mechanism 10 to have not only a clamping state but also an open state, so that the detection mechanism 10 can not only be installed on the pole fuse but also be removed from the pole fuse. The other part is the installation mechanism 20, which can be docked with the detection mechanism 10 to transport the detection mechanism 10 to the pole fuse or remove it from the pole fuse, so that when the pole fuse is in working state, the status detection member 15 can also be freely disassembled and assembled. When in use, the personnel adjust the locking member 12 to the locking state on the ground. At this time, the detection mechanism 10 is kept in the clamping state due to the action of the locking member 12. Then the detection mechanism 10 can be docked on the base 21 of the installation mechanism 20. The personnel can send the detection mechanism 10 to a high place through the insulating member 22. When the pole fuse extends into the clamping area, the locking member 12 is in the clamping area, so that the pole fuse will push the locking member 12 to move, so that the locking member 12 releases the abutment relationship with the clamping member 11. At this time, the clamping area is closed under the action of the reset member 13 because there is no locking member 12 to hold it, so that it is clamped on the pole fuse. The personnel can complete the installation of the detection mechanism 10 by retracting the installation mechanism 20. The detection mechanism 10 can detect the state of the pole fuse through the state detection member 15 thereon. The above-mentioned setting method enables the pole fuse to be easily and quickly installed and disassembled even in the working state, and the replacement and maintenance functions can be easily realized, and the real-time monitoring of the state of the pole fuse can also be realized.

[0036] This embodiment is described by taking two clamping members 11 as an example, the two clamping members 11 form an annular clamping area, and the locking member 12 is arranged between the two clamping members 11. Of course, the number of the clamping members 11 can also be adjusted as needed, as long as they can be clamped on the outside of the column fuse to achieve a clamping effect. In this case, it is sufficient to arrange a locking member 12 between any two clamping members 11, and it is not necessary to arrange a locking member 12 between all the clamping members 11.

[0037] like Figure 1As shown, in this embodiment, the clamping member 11 includes a main body clamping jaw and a convex column 111, wherein the main body clamping jaw has a semi-arc shape, which forms a clamping area, and the convex column 111 is penetrated on the main body clamping jaw, and the convex column 111 can be integrally fixed on the main body clamping jaw, and can also be separately and detachably penetrated on the main body clamping jaw. The locking member 12 has a slide groove 121, and the boss 111 is located in the slide groove 121 and can move in the slide groove 121, so that the clamping member 11 has different states, thereby realizing the clamping function. Specifically, the slide groove 121 includes a first section and a second section that are bent and connected. When the boss 111 is located in the first section, the movement of the boss 111 in the first section of the slide groove 121 allows the clamping members 11 to change the distance between each other, thereby allowing the clamping member 11 to be opened or closed; when the boss 111 is located in the second section, the boss 111 abuts against the side wall of the second section, and the locking member 12 is in a locked state, locking the boss 111 in the second section of the slide groove 121, thereby hindering the movement of the clamping members 11 approaching each other, thereby locking the position of the clamping member 11, so that the clamping member 11 is in an open state, such as Figure 3 and Figure 4 shown.

[0038] In this embodiment, the second section has a free end and a connecting end connected to the first section. The direction from the connecting end to the free end forms an angle less than 90 degrees with the direction in which the column fuse extends into the clamping area, so that when the column fuse extends into the clamping area, it pushes the locking piece 12 to move, thereby allowing the protruding column 111 to move from the second section to the first section. In this embodiment, when the boss 111 is located in the first section of the slide slot 121, the extension direction of the second section of the slide slot 121 is parallel to the direction in which the column fuse extends into the clamping area, and the free end is located in the direction away from the column fuse. The extension direction of the second section is perpendicular to the extension direction of the first section, and the extension direction of the first section is roughly along the movement direction of the clamping member opening and closing. In this way, the slide slot 121 forms an L-shaped structure. On the one hand, when the boss 111 is located in the first section, the clamping member 11 can be opened and closed, and when the boss 111 is located in the second section, when the column fuse extends into the clamping area, the column fuse can push the locking member 12, so that the boss 111 in the slide slot 121 moves from the second section to the first section, thereby releasing the locking member 12 on the clamping member 11, so that the boss 111 can move along the slide slot 121 in the first section, thereby realizing the opening or closing of the clamping member 11. Of course, the extension directions of the first section and the second section can be adjusted accordingly as needed, as long as it can be ensured that the clamping member 11 can be opened and closed when the boss 111 is located in the first section and remains open when located in the second section.

[0039] In this embodiment, the clamping members 11 are rotatably arranged in pairs. The two clamping members 11 are connected together by a pivot shaft on the side away from the entrance of the clamping area, so as to realize the clamping and opening of the detection mechanism 10 through the rotational cooperation of the two clamping members 11. Among the two clamping members 11 arranged in pairs, one clamping member 11 has a convex post 111, and the convex post 111 cooperates with the above-mentioned chute 121. The other clamping member 11 has a connecting post. The arrangement of the connecting post and the convex post 111 can be the same or different. In this embodiment, the same arrangement is adopted, that is, the connecting post can also be regarded as the convex post 111 in essence, as long as the cooperation mode with the locking member 12 is exchanged. Different from the cooperation mode of the convex post 111, although the connecting post in this embodiment also passes through the locking member 12, it has only a rotatable movement form relative to the locking member 12. Specifically, the locking member 12 has a mounting hole, which is located at a section of the first section away from the second section. The shape of the mounting hole is the same as that of the connecting post, and their sizes are basically equal. The connecting post passes through the mounting hole, so as to connect the locking member 12 and the clamping member 11 together and make the locking member 12 and the clamping member 11 with the connecting post rotatably connected. In this way, the locking member 12 connects the two clamping members 11 into a whole. When in use, only need to rotate the locking member 12 to rotate it relative to the connecting post, so that the convex post 111 can be switched between the first section and the second section, realizing the control of the locking member 12 to open and close the detection mechanism 10.

[0040] It should be noted that in addition to the above-mentioned cooperation mode between the locking member 12 and the convex post 111 and the connecting post in this embodiment, the cooperation form in which the locking member 12 and both clamping members 11 adopt the convex post 111 can also be adopted, that is, the two clamping members 11 are provided with convex posts 111. The chute 121 of the locking member 12 is divided into three sections, namely the second section, the first section, and the other second section that are sequentially bent and connected. The bending directions of the two second sections relative to the first section are the same, so that the chute 121 forms a U-shaped structure form. The convex posts 111 of each clamping member 11 are respectively synchronously cooperated with the two second sections, and the effect of keeping the clamping member 11 open can also be achieved.

[0041] In this embodiment, the main jaw of the clamping member 11 also has a sliding groove 112, and the detection mechanism 10 also includes an unlocking member 14, which is inserted into the sliding groove 112. The cooperation between the unlocking member 14 and the main jaw can also adopt the cooperation between the aforementioned convex column 111 and the main jaw, that is, the unlocking member 14 and the main jaw can be arranged in an integral or separate manner, and the unlocking member 14 can also adopt the shape of the convex column 111. Different from the cooperation relationship between the aforementioned convex column 111 and the connecting column, the component that the unlocking member 14 cooperates with is the reset member 13, and the reset member 13 is connected to the unlocking member 14. Since the reset member 13 of this embodiment adopts a spring, the end of the spring can be sleeved on the outside of the unlocking member 14, and the unlocking member 14 can move in the sliding groove 112, thereby driving the movement of the reset member 13, controlling the tension and relaxation of the reset member 13, and thus can cooperate with the locking member 12 to realize the opening and closing of the clamping member 11. Specifically, the two clamping members 11 arranged in pairs are connected into a whole through the reset member 13 and the unlocking member 14, and the unlocking member 14 is located on one of the clamping members 11. One end of the reset member 13 is connected to the clamping member 11 having the sliding groove 112 through the unlocking member 14, and the other end is rotatably connected to the other clamping member 11. In this way, when the unlocking member 14 moves in the sliding groove 112, the unlocking member 14 can drive the reset member 13 to be tightened and relaxed, so that the reset member 13 applies a pulling force to the two clamping members 11 to approach each other and close the clamping area, or the reset member 13 no longer applies force to the clamping member 11 so that the clamping area can be opened, such as Figure 5 and Figure 6 shown.

[0042] Similar to the structural form of the aforementioned sliding groove 121, the sliding groove 112 in this embodiment includes a first sliding section and a second sliding section that are bent and connected, and an angle of no more than 90° is formed between the two. The extension direction of the first sliding section is roughly parallel to the extension direction of the reset member 13, that is, roughly perpendicular to the direction in which the column fuse extends into the clamping area. Preferably, the first sliding section and the second sliding section are vertically arranged, so that the sliding groove 112 forms an L-shaped structure, and the second sliding section is located on the side of the first sliding section away from the clamping area, that is, away from the side of the other clamping member 11 arranged in pair. In this way, the unlocking member 14 is moved in the first sliding section toward When moving in the direction away from the second sliding section, the reset member 13 can be relaxed, and when the unlocking member 14 moves in the direction from the first sliding section to the second sliding section, the reset member 13 is gradually tightened until the unlocking member 14 switches from the first sliding section to the second sliding section. The reset member 13 applies a force to the clamping member 11 that approaches each other and is perpendicular to the extension direction of the second sliding section. The side wall of the second sliding section abuts against the stopper of the unlocking member 14, so that the unlocking member 14 is restricted in the second sliding section, thereby keeping the reset member 13 stretched and tensioned. At this time, if the boss 111 is located in the first section of the slide groove 121, the clamping member 11 can be automatically clamped.

[0043] Similar to the aforementioned chute 121, the sliding groove 112 in this embodiment can also adopt a U-shaped structure. At this time, unlocking members 14 can be provided on both clamping members 11, and the two unlocking members 14 can act synchronously, so as to realize the tensioning and relaxation of the reset member 13 through the actions of the two unlocking members 14.

[0044] The state detection member 15 in this embodiment can be set as an angle sensor and fixed to the clamping member 11. Preferably, the angle sensor can identify the device state and report signals in real time when abnormal. After the detection mechanism 10 is installed, the angle sensor is fixed to the fuse cartridge along with the detection mechanism 10; when the current exceeds the specified value, the fuse element of the pole-mounted fuse generates heat by itself to fuse the fuse element, and the fuse cartridge drops under the action of gravity, and the angle sensor follows the movement and thus changes the angle. The angle sensor sends an alarm signal to the corresponding receiving system, so as to monitor the fuse state in real time. Preferably, each detection mechanism 10 has a unique signal, which can quickly determine and find the abnormal position when an abnormality occurs, and the management personnel can handle it in time to avoid losses caused by accidents.

[0045] Friction members such as rubber sheets can be provided at the inner wall of the clamping area where the clamping member 11 in this embodiment cooperates with the pole-mounted fuse. The friction members can be fixed to the clamping member 11 using adhesives, so as to provide greater friction for the clamping member 11 and ensure the clamping reliability.

[0046] It should be noted that the detection mechanism 10 includes three states during the installation and disassembly process, namely the clamping state ( Figure 3 ), the open state ( Figure 4 ), and the non-pre-tightened state ( Figure 5). The reset member 13 of the detection mechanism 10 can provide a clamping force for the two clamping members 11. Under normal circumstances, the reset member 13 is in a free state and is not subjected to any external force. When we move the unlocking member 14 from the first sliding section of the sliding groove 112 to the second sliding section, the reset member 13 is stretched and is in an elastic deformation state. At this time, the two clamping members 11 are subjected to the pulling force of the reset member 13 to shrink inward. The unlocking member 14 will always maintain this state in the absence of external force in the second sliding section, and continuously provide clamping force for the detection mechanism 10. In this state, the two clamping members 11 are opened, and then the locking member 12 is pushed, so that the convex column 111 of the clamping member 11 provided with the convex column 111 enters the second section of the locking member 12. At this time, the reset member 13 is opened to provide a pulling force for the clamping member 11, but due to the obstruction of the locking member 12, the clamping member 11 remains in an open state, which is an open state. In the open state, the locking member 12 is pushed to make the boss 111 withdraw from the second section of the slide groove 121, and the two clamping members 11 are contracted and clamped inwardly under the action of the reset member 13 until the fuse tube is clamped, which is the clamping state. In the clamping state, the unlocking member 14 is switched to the first sliding section of the sliding groove 112, the reset member 13 is in a relaxed state, the boss 111 is located in the first section of the locking member 12, the locking member 12 does not lock the clamping member 11, and the clamping member 11 can be opened freely, which is the non-preloaded state.

[0047] like Figure 2 , Figure 6 and Figure 8 As shown, the mounting mechanism 20 in this embodiment also includes a control member 23, which is movably connected to the base 21, and when the base 21 is docked with the detection mechanism 10, the movement trajectories of the control member 23 and the unlocking member 14 are located in the same plane, so that the control member 23 is docked with the unlocking member 14, and the control member 23 can push the unlocking member 14 to move, thereby driving the unlocking member 14 to move from the second sliding section to the first sliding section, thereby releasing the lock of the reset member 13 on the clamping member 11, and then allowing the clamping area to be opened, so that the detection mechanism 10 can be disassembled.

[0048] In this embodiment, the control member 23 includes a push block 231 and a first knob 232. The base 21 has a groove. When the base 21 is connected to the detection mechanism 10, the groove faces the unlocking member 14. The push block 231 is movably arranged in the groove. The first knob 232 is threadedly connected to the base 21 and connected to the push block 231. When the first knob 232 is rotated, the push block 231 is driven to move in the groove to drive the unlocking member 14 to move from the second sliding section to the first sliding section. In this way, when the push block 231 is located at the bottom of the groove, the base 21 and the detection mechanism 10 are connected. When the detection mechanism 10 is docked, the push block 231 and the unlocking member 14 do not interfere with each other, and the control member 23 does not have any effect on the detection mechanism 10; when the first knob 232 is turned to push the push block 231 to a position away from the bottom of the groove, the base 21 is docked with the detection mechanism 10, and the push block 231 pushes the unlocking member 14 to move away from the base 21, so that the unlocking member 14 moves from the second sliding section to the first sliding section, and the reset member 13 is relaxed, thereby releasing the lock of the unlocking member 14 and the reset member 13 on the clamping member 11.

[0049] In this embodiment, the base 21 has an installation area for accommodating at least part of the detection mechanism 10, so that when the base 21 is docked with the detection mechanism 10, the detection mechanism 10 can be embedded in the installation area to achieve positioning. The installation mechanism 20 also includes a clamping component 24, which is penetrated on the base 21 and movably connected with the base 21. The clamping member 11 has a clamping hole. When the base 21 is docked with the detection mechanism 10, the base 21 is located in the installation area, and the clamping component 24 is aligned with the clamping hole, so that the clamping component 24 can extend into the clamping hole, thereby fastening the detection mechanism 10 to the installation mechanism 20, preventing the detection mechanism 10 from falling off, and realizing the transportation of the detection mechanism 10 to the height where the fuse on the column is located.

[0050] In the present embodiment, two clamping components 24 are provided. Of course, additional clamping components 24 can be provided as needed. The two clamping components 24 are symmetrically arranged on the opposite sides of the installation area. Correspondingly, two clamping holes are also provided, and are symmetrically opened on two sides of the clamping parts 11 arranged in pairs and away from each other, so that the clamping components 24 and the clamping holes are matched one by one. The symmetrical arrangement can ensure that the force applied by the clamping components 24 to tighten the detection mechanism 10 is balanced, thereby improving reliability.

[0051] like Figures 6 to 9As shown, in this embodiment, the clamping assembly 24 includes a movable column 241, a second knob 242, and an elastic member 243. The movable column 241 is rotatably and axially movable on the base 21. The end of the movable column 241 extending into the base 21 has an inclined surface. When the movable column 241 rotates, the inclined surface faces or faces away from the entrance side of the installation area; the second knob 242 is located on the outside of the base 21, which is connected to the movable column 241 and drives the movable column 241 to rotate to change the direction of the inclined surface; the elastic member 243 abuts against the movable column 241 and provides elastic force for the movable column 241 to move in the direction of extending into the clamping hole. The elastic member 243 can be set as a spring. Specifically, when the detection mechanism 10 needs to be detached from the base 21, the inclined surface of the movable column 241 faces away from the entrance side of the installation area, that is, Fig. 9 The inclined surface is forced to move outward, and the elastic member 243 is compressed, thereby driving the movable column 241 to move in the direction away from the clamping hole, so that the movable column 241 is separated from the clamping hole, and the detection mechanism 10 can be separated from the base 21, thereby being separated from the installation mechanism 20, so that the installation mechanism 20 can be recycled; when the detection mechanism 10 needs to be docked into the base 21, the inclined surface of the movable column 241 faces the entrance side of the installation area, that is, Figure 7 The movable column 241 is connected to the clamping hole, and the elastic member 243 is restored to a free state, so that the movable column 241 is located in the clamping hole, and the detection mechanism 10 is fixed to the base 21, so that the installation mechanism 20 can drive the detection mechanism 10 to move. In this way, the installation and disassembly functions are integrated into one mechanism, and the state of the installation mechanism 20 can be switched by adjusting the first knob 232 and the second knob 242, so that convenient disassembly and assembly can be achieved.

[0052] The movable column 241 of this embodiment includes three segments connected axially in sequence, namely, a cylindrical section, a square section and a transmission section, wherein the end of the cylindrical section has an inclined surface, and the end of the transmission section has a transmission structure matched with the second knob 242. Correspondingly, the clamping hole includes a cylindrical hole and a square hole arranged in sequence axially, and the size of the square hole is substantially the same as that of the square section. In this way, when the movable column 241 is only acted upon by the elastic member 243, the cylindrical section is located in the cylindrical hole, and the square section is located in the square hole. Due to the cooperation between the square section and the square hole, the movable column 241 cannot rotate at will. When it is necessary to rotate, the personnel axially pulls the second knob 242 to make the square section disengage from the square hole. At this time, the movable column 241 can rotate. The personnel rotate the second knob 242 to change the direction of the inclined surface. After the rotation is completed, the personnel releases the second knob 242, and the square section can automatically enter the square hole, thereby limiting the rotation of the movable column 241. In this way, the movable column 241 cannot rotate automatically, thereby ensuring the stability of the inclined surface direction.

[0053] The clamping hole of this embodiment is also provided with a larger avoidance hole on the side of the square hole away from the cylindrical hole. The size of the avoidance hole is much larger than the size of the square segment, so that when the second knob 242 is pulled out, the square segment is located in the avoidance hole and can rotate freely in the avoidance hole. At the same time, the clamping assembly 24 of this embodiment also includes a fixing member, which is connected to the outer surface of the base 21 and covers the clamping hole. Only the transmission segment can pass through the fixing member, thereby achieving the effect of stably mounting the movable column 241 on the base 21.

[0054] It should be noted that the installation mechanism 20 includes two modes during the installation and removal of the detection mechanism 10, namely, the installation mode and the removal mode. Figure 8 and Fig. 9 As shown, the installation mode is to rotate the first knob 232 to move the push block 231 to the lowest position of the groove of the base 21; rotate the two second knobs 242 to move the inclined surface of the movable column 241 away from the entrance side of the installation area, and the installation mechanism 20 is in the installation mode. Figure 6 and Figure 7 As shown, the disassembly mode is to rotate the first knob 232 to move the push block 231 to the highest position of the groove of the base 21, rotate the two second knobs 242, and move the inclined surface of the movable column 241 toward the entrance side of the installation area. At this time, the installation mechanism 20 is in the disassembly mode.

[0055] like Figures 10 to 12 As shown, the specific use process of the pole-mounted fuse status detection and maintenance device of this embodiment includes the installation process of the detection mechanism 10 and the disassembly process of the detection mechanism 10, wherein:

[0056] The process of installing the detection mechanism 10 to the pole fuse is as follows: adjust the installation mechanism 20 to the installation mode and keep the clamping member 11 of the detection mechanism 10 in the open state, pull out the second knob 242 and place the detection mechanism 10 on the installation mechanism 20, release the second knob 242, and under the action of the clamping assembly 24, the detection mechanism 10 will be fixed on the installation mechanism 20. At this time, lift the insulating member 22 to push the pole fuse status detection and maintenance device to the fuse tube position of the pole fuse, push it in with force, and the locking member 12 of the clamping member 11 touches the fuse tube and moves away from the fuse tube. The two clamping members 11 clamp the fuse tube under the action of the reset member 13, and the installation mechanism 20 is retracted, and the installation process of the detection mechanism 10 is completed;

[0057] The process of disassembling the detection mechanism 10 from the pole-mounted fuse is as follows: adjust the installation mechanism 20 to the disassembly mode, lift the insulating part 22 close to the pole-mounted fuse sensor, and cover the installation mechanism 20 with the detection mechanism 10. At this time, the clamping assembly 24 clamps the detection mechanism 10, and at the same time, the push block 231 on the installation mechanism 20 will push the unlocking part 14 on the detection mechanism 10 to leave the second sliding section, so that the reset part 13 loses its elastic force, and there is no longer a clamping force between the two clamping parts 11. The detection mechanism 10 no longer maintains a clamped state, and the installation mechanism 20 is retracted, and the disassembly process of the detection mechanism 10 is completed.

[0058] It should be noted that during the entire installation and disassembly process of the pole-mounted fuse status detection and maintenance device, the operation direction is the same direction, which is opposite to the falling direction of the pole-mounted fuse during its working process, so the installation and disassembly process will not cause the pole-mounted fuse to fall accidentally.
