[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] In the drawings, the first direction is shown as the X direction, and the second direction perpendicular to the first direction is shown as the Y direction. Figure 1-Figure 9As shown, this embodiment provides an auxiliary fixing device, which includes a wearing component 1, an adjustment component, a fixing component 6 and a balancing component 4. The wearing component 1 is used to be detachably fixed to the human body; the adjustment component includes a first telescopic member 2 and a second telescopic member 3, one end of the first telescopic member 2 is fixedly connected to the wearing component 1, and the other end is a telescopic end connected to the second telescopic member 3, the first telescopic member 2 can be damped and telescopic along the first direction, and the second telescopic member 3 can be damped and telescopic along the second direction; the fixing component 6 is arranged at one end of the second telescopic member 3 away from the first telescopic member 2, and the fixing component 6 is used to fix the detection equipment; the balancing component 4 includes a motion conversion mechanism and a counterweight 401, the counterweight 401 is located at one end of the first telescopic member 2 away from the second telescopic member 3, the motion conversion mechanism is arranged between the first telescopic member 2 and the counterweight 401, when the first telescopic member 2 is telescoped along the first direction, the motion conversion mechanism can drive the counterweight 401 to move in the opposite direction to the motion direction of the first telescopic member 2.

[0043] Specifically, the wearing component 1 is a flexible fixing part, which includes a waist ring 101 and a shoulder strap 102 connected to the waist ring 101. The user can fix other components to the human body relatively through the cooperation of the waist ring 101 and the shoulder strap 102, freeing up the hand space of the user. Further, the waist ring 101 can be detachably fixed to the waist of the operator, and other components can be arranged on the waist ring 101 to achieve relative fixation with the human body. In addition, the two shoulder straps 102 are respectively located on the left and right sides of the waist ring 101 to fit with the shoulders of the human body, thereby improving the bearing capacity and stability of the waist ring 101. Further, the waist ring 101 and / or the shoulder strap 102 can be detachably fixed on the human body through Velcro 103, making the wearing and removal of the auxiliary fixing device as a whole more convenient and quick. Further, the waist ring 101 and the shoulder strap 102 can adopt elastic belts to improve the comfort when wearing and the fit with the human body.

[0044] Specifically, when the human body is standing normally, the first telescopic member 2 is fixed on the waist ring 101, the first telescopic member 2 moves forward and backward in the horizontal direction, and the second telescopic member 3 moves up and down in the vertical direction. That is, taking the waist of the user as the reference system, the first direction X is the front-back direction, the second direction Y is the vertical direction, and the first direction is perpendicular to the second direction. Therefore, the coordinated movement of the first telescopic member 2 and the second telescopic member 3 can adjust the fixed component 6 located at the end of the second telescopic member 3 to a position that is convenient for the user to operate or watch. At the same time, the damping telescopic characteristic ensures that the first telescopic member 2 and the second telescopic member 3 will not change their own lengths due to external minor disturbances after adjusting their positions, thereby affecting the positioning effect of the fixed component 6. Furthermore, there are two first telescopic parts 2, which are respectively fixedly connected to the left and right sides of the waist ring 101, and can be damped and telescopic along the front and rear directions; there are also two second telescopic parts 3, which are respectively fixedly connected to the telescopic ends of the first telescopic part 2, and can be damped and telescopic along the up and down directions; there are two fixed components 6, which are respectively arranged on the end of the second telescopic part 3 away from the first telescopic part 2, and are used to clamp the detection equipment for intelligent distribution network fault maintenance. The two fixed components 6 can respectively clamp different detection equipment such as a discharge detector and an ultrasonic probe.

[0045] Furthermore, the fixing assembly 6 is an electric clamping assembly, and a controller 612 is also provided in the auxiliary fixing device. The controller 612 can control the electric clamping assembly to clamp the detection equipment, so as to avoid the operator having to manually clamp and fix the detection equipment. The controller 612 can be provided on the waist ring 101 or on the adjustment assembly. The controller 612 can adopt the controller 612 in the prior art, such as the controller 612 of model S7-300. The present embodiment does not limit the model and setting position of the controller 612. In addition, a battery 5 is also provided in the auxiliary fixing device, and the battery 5 is electrically connected to each electrical component to provide electrical energy. The power supply assembly can be provided on the waist ring 101 or on the adjustment assembly or the fixing assembly 6. The present embodiment does not limit this.

[0046] In some other implementations, the fixing component 6 may be provided with a snap-in groove, which can snap-in and fix the detection device, and the detection device may also be magnetically fixed by providing a magnetic attraction member, which is not limited in this embodiment.

[0047] Specifically, when the fixing component 6 clamps the detection device, since the detection device itself has a certain gravity, adjusting the first telescopic member 2 to extend forward and backward along the first direction will cause the detection device to move away from or close to the human body. At this time, the torque generated by the detection device is the product of its own gravity and the length of the lever arm. When the first telescopic member 2 is extended, the torque increases, which easily drives the entire auxiliary fixing device to tilt downward and also easily causes the center of gravity of the user to be unstable, affecting the use effect. For this reason, a balancing component 4 is set. When the first telescopic member 2 is extended, the balancing component 4 drives the counterweight 401 to move backward, relying on the torque generated by the counterweight 401 to reduce the tilt of the device, and then the user is balanced in front and back forces, ensuring the use effect of the auxiliary fixing device.

[0048] Therefore, the use of the above-mentioned auxiliary fixing device can save the operator from continuously holding the detection equipment and setting the detection equipment in an appropriate position during the inspection and maintenance of the intelligent distribution network through the adjustment component and the fixing component 6, so that the operator can use both hands to perform more maintenance and inspection operations while using the detection equipment for inspection, which helps to improve the efficiency of inspection and maintenance. The balancing component 4 can prevent the auxiliary fixing device from tilting due to the torque change generated by the operator adjusting the position of the fixing component 6, thereby improving the stability and operating experience of the auxiliary fixing device when in use.

[0049] Furthermore, in this embodiment, the battery 5 can be arranged at the waist ring 101 and then connected to each electrical appliance through a line, so as to avoid the self-weight of the battery 5 generating a large torque at the fixing component 6, which affects the user experience. Furthermore, the battery 5 is arranged in the counterweight 401, and the self-weight of the battery 5 is used for counterweighting, so that the weight of the battery 5 is fully utilized through spatial layout, and the material consumption of the counterweight 401 is reduced, thereby improving resource utilization.

[0050] Further, in the present embodiment, the first telescopic member 2 comprises a hollow first fixed tube 201 and a first movable tube 202 arranged in the first fixed tube 201, one of the outer wall of the first movable tube 202 and the inner wall of the first fixed tube 201 is provided with at least one first elastic block, and the other is provided with a plurality of first slots, the first elastic block can be elastically inserted into the first slot, and the plurality of first slots are arranged at intervals along the movement direction of the first movable tube 202; the second telescopic member 3 comprises a hollow second fixed tube 301 and a second movable tube 302 arranged in the second fixed tube 301, one of the outer wall of the second movable tube 302 and the inner wall of the second fixed tube 301 is provided with at least one second elastic block 305, and the other is provided with a plurality of second slots 306, the second elastic block 305 can be elastically inserted into the second slot 306, and the plurality of second slots 306 are arranged along the movement direction of the second movable tube 302. It can be understood that, taking the first telescopic member 2 as an example, the space in the first slot is slightly larger than the size of the first elastic block, and the plurality of first slots are arranged along the movement direction of the first movable tube 202, so the first elastic block can enter different first elastic slots to achieve the relative fixation of the first movable tube 202 and the first fixed tube 201 at different positions. In one embodiment, the first slot is provided on the inner wall surface of the first fixed tube 201, and the elastic block is provided on the outer wall surface of the first movable tube 202. The user can apply a force to the first movable tube 202 away from or close to the human body, and the first elastic block located in the first movable tube 202 and the corresponding first slot will change the clamping state accordingly. The first elastic block will undergo elastic deformation under the action of external force and detach from the original first slot. After moving to a suitable position, the deformation is restored and clamped with the new first slot, so that the first movable tube 202 can be pulled to the desired position and fixed, thereby achieving the damping expansion and contraction of the first telescopic member 2.

[0051] In some other embodiments, the first card slot can also be arranged on the outer wall of the first movable tube 202, and the first elastic card block can be arranged on the inner wall of the first fixed tube 201; or the hollow first movable tube 202 can be sleeved outside the first fixed tube 201, and the first card slot and the first elastic card block can be directly arranged on the first movable tube 202 and the first fixed tube 201, which is not limited in this embodiment. It can be understood that the damping telescopic principle of the second telescopic member 3 is the same as that of the first telescopic member 2, and will not be repeated in this embodiment.

[0052] Furthermore, in this embodiment, the inner wall of the first fixed tube 201 is provided with a first abutting portion, and the outer wall of the first movable tube 202 is provided with a first limiting protrusion 203. When the first movable tube 202 is away from the first fixed tube 201, the first abutting portion can abut against the first limiting protrusion 203 for limiting position; the inner wall of the second fixed tube 301 is provided with a second abutting portion, and the outer wall of the second movable tube 302 is provided with a second limiting protrusion 303. When the second movable tube 302 is away from the second fixed tube 301, the second abutting portion can abut against the second limiting protrusion 303 for limiting position. It can be understood that the first fixed tube 201 and the first movable tube 202 are movably connected, and the length of the first fixed tube 201 is limited, so a certain limiting structure needs to be provided to prevent the user from adjusting the first telescopic member 2 to pull the first movable tube 202 out of the first fixed tube 201, thereby affecting the auxiliary fixing effect of the detection device. Taking the first telescopic member 2 as an example, the end of the first movable tube 202 close to the waist ring 101 is provided with a first limiting protrusion 203, and the end of the first fixed tube 201 away from the waist ring 101 is provided with a first abutting portion. When the first movable tube 202 is about to be pulled out of the first fixed tube 201, the first limiting protrusion 203 will abut against the first abutting portion to limit the position, and then continue to stay in the first fixed tube 201. Further, the end of the first movable tube 202 close to the waist ring 101 is provided with a first limiting plate, and the first limiting plate is used as the first limiting protrusion 203. The end of the first fixed tube 201 away from the waist ring 101 has an opening, and the first movable tube 202 extends out of the first fixed tube 201 through the opening, and the cross-sectional area of ​​the opening is smaller than the first movable tube 202, so the inner wall of the first fixed tube 201 can be used as a first abutting portion to abut against the first limiting plate to limit the position. It can be understood that the limiting principle of the second telescopic member 3 is the same as that of the first telescopic member 2, and this embodiment will not be repeated.

[0053] Furthermore, in this embodiment, the balancing assembly 4 further includes a connecting member 402, which is slidably connected to the first fixed tube 201 and passes through an end of the first fixed tube 201 away from the second telescopic member 3, and the counterweight 401 is arranged at an end of the connecting member 402 away from the second telescopic member 3, and the motion conversion mechanism includes a rotating wheel, and the first movable tube 202 can drive the rotating wheel to rotate, so that the rotating wheel drives the connecting member 402 to move in the opposite direction of the movement direction of the first movable tube 202. When the first movable tube 202 is pulled, the first movable tube 202 drives the rotating wheel to rotate, and the connecting member 402 and the first movable tube 202 are respectively located on both sides of the rotating wheel. When the rotating wheel rotates, the linear velocity directions of the two sides are opposite, so the connecting member 402 can be driven to move in the opposite direction of the movement direction of the first movable tube 202. That is, when the first movable tube 202 is pulled out, the connecting member 402 drives the counterweight 401 away from the waist ring 101, and the torques generated at the front and rear positions of the human body increase and offset each other. When the first movable tube 202 is retracted, the counterweight 401 approaches the waist ring 101, and the torques generated at the front and rear positions of the human body decrease and offset each other. It can be understood that in actual use, the weight of the counterweight 401 can be specifically set according to the weight of the detection component so that the torques generated by the two are always balanced.

[0054] Furthermore, in this embodiment, at least two rotating wheels are provided, and at least two rotating wheels are arranged at intervals along the first direction, and at least two rotating wheels are provided with transmission belts 404 around them, and the outer surface of the transmission belt 404 abuts against the first movable tube 202 on one side along the second direction, and abuts against the connecting member 402 on the other side. The rotating wheels include a first rotating wheel 405 and a second rotating wheel 406, and a belt is wound around the first rotating wheel 405 and the second rotating wheel 406, and the upper surface of the belt is connected to the lower surface of the connecting member 402, and the lower surface of the belt is connected to the upper surface of the first movable tube 202. When the first movable tube 202 moves in the first fixed tube 201, it will drive the lower surface of the belt to move, and the upper surface of the belt has a movement direction opposite to that of the lower surface under the cooperation of the first rotating wheel 405 and the second rotating wheel 406, so that the connecting member 402 drives the counterweight 401 to move in the opposite direction of the movement direction of the first movable tube 202, balancing the torque generated by the fixed assembly 6. Furthermore, the connecting member 402 and the first movable tube 202 are both fixedly connected to the belt. When the first movable tube 202 is inserted into the first fixed tube 201 to the maximum extent, the inner end of the first movable tube 202 is located near the second rotating wheel 406 and is fixedly connected to the belt below the second rotating wheel 406 through the fixed structure. At this time, the insertion end of the connecting member 402 is located at the first rotating wheel 405 and is fixedly connected to the belt above the second rotating wheel 406 through the fixed structure. When the first movable tube 202 moves, the fixed structures above and below the belt can keep moving in the first direction to ensure the effect of motion conversion. Furthermore, an additional accommodating cavity for the connecting member 402, the first rotating wheel 405, the second rotating wheel 406 and the belt is integrally provided above the first fixed tube 201. A ball 403 is provided between the connecting member 402 and the accommodating cavity to convert sliding friction into rolling friction to reduce the friction between the connecting member 402 and the inner wall of the accommodating cavity.

[0055] In some other embodiments, a belt may not be provided, but a gear may be provided at the rotating wheel, and teeth may be provided at the first movable tube 202 and the connecting member 402, and the gears may mesh with the teeth to realize the function of motion conversion.

[0056] Specifically, in this embodiment, a bearing platform 304 is provided at one end of the second telescopic member 3 away from the first telescopic member 2, and the fixed component 6 is connected to the bearing platform 304 by damping rotation. When the operator uses the clamping auxiliary device, the fixed component 6 on the rotating bearing platform 304 can adjust the direction of the detection device, so that while the operator is working, the detection device can detect the intelligent distribution network in other directions, or the detection device on the fixed component 6 located at the side of the operator can detect the intelligent distribution network directly in front of the operator. At the same time, the damping rotation can ensure that after the operator adjusts the angle of the fixed component 6, the fixed component 6 can remain in a fixed position, avoiding the detection device on the fixed component 6 from rotating due to a small external force, which affects the detection effect.

[0057] Further, in this embodiment, the bearing platform 304 includes an annular magnet groove 3041, and the fixed component 6 is provided with a guide magnet protrusion 6011, which extends into the annular magnet groove 3041 and is rotatably connected to the annular magnet groove 3041. The bearing platform 304 is a flat plate structure, which is fixedly connected to the telescopic end of the second telescopic member 3, and a circular groove is provided on the flat plate structure, and a magnet is provided in the groove to make the groove become an annular magnet groove 3041. The bottom of the fixed component 6 is provided with a plurality of guide magnetic rods, which are used as guide magnetic rods as guide magnetic protrusions 6011, and the guide magnetic rods and the annular magnet groove 3041 can attract each other, and the plurality of guide magnetic rods extend into the annular magnet groove 3041 to realize the damping rotation of the fixed component 6 and the bearing platform 304. Furthermore, a magnetic ring 3042 is laid on the bottom of the groove, and a force is applied to the guide magnetic rod through the magnetic ring 3042. Furthermore, a rotating plate 601 is connected above the guide magnetic rod, and the upper surface of the rotating plate 601 is used to set the fixing assembly 6 for clamping other components of the detection device, so that the rotating plate 601 drives the other components to rotate. In some other embodiments, the magnetic ring 3042 may not be laid, but a groove may be opened in the whole magnet to achieve damped rotation of the fixing assembly 6.

[0058] Specifically, in this embodiment, the fixed component 6 includes a controller 612, a linear drive mechanism, and a first clamp and a second clamp that are arranged oppositely. The controller 612 is electrically connected to the linear drive mechanism, and the first clamp and / or the second clamp are connected to the output end of the linear drive mechanism. The linear drive mechanism can drive the first clamp and / or the second clamp to move closer to or farther from each other. Two electric telescopic rods 608 are arranged in the fixed component 6, and a clamp 609 is arranged at one end close to each other. The controller 612 controls the telescopic movement of the electric telescopic rod 608 to control the clamp 609 to clamp or loosen the detection device, which reduces the steps for the operator to manually clamp and fix the detection device, and is more convenient and quick. It can be understood that the electric telescopic rod 608 can also be arranged at only one clamp 609, and controlling the movement of a single clamp 609 can also achieve the clamping or loosening of the detection device. In addition, a driving cylinder, a nut screw and other structures can also be arranged as a linear motion mechanism to control the position of the clamp 609, and this embodiment does not limit this.

[0059] Further, in this embodiment, the fixing assembly 6 also includes a placement table 605, a first clamping member and a second clamping member are arranged on the placement table 605, a first pressure-sensitive member 607 is arranged on the upper surface of the placement table 605, and the first pressure-sensitive member 607 is communicatively connected with the controller 612. A mounting seat 606 is arranged on the placement table 605, two mutually symmetrical electric telescopic rods 608 are fixedly mounted on the mounting seat 606, a first pressure-sensitive member 607 is arranged on the upper surface of the placement table 605, and the first pressure-sensitive member 607 is communicatively connected with the controller 612. The upper surface of the placement table 605 is used to place the detection equipment, and when the detection equipment is placed, the electric telescopic rod 608 drives the clamping plate 609 to clamp the detection equipment. The first pressure-sensitive member 607 is arranged on the upper surface of the placement table 605, and after the detection equipment is placed, the first pressure-sensitive member 607 can generate a corresponding signal and transmit the signal to the controller 612, and the controller 612 then controls the electric telescopic rod 608 to move to clamp the detection equipment. Furthermore, a concave cavity is provided on the upper surface of the placement table 605, and the first pressure-sensitive component 607 is arranged in the concave cavity. The cavity can be filled with rubber material, and the pressure generated by the detection equipment can be transmitted to the first pressure-sensitive component 607 through the filling material. The setting of the concave cavity can prevent the first pressure-sensitive component 607 from being exposed to the outside world, and can also prevent the first pressure-sensitive component 607 from directly contacting the detection equipment to cause extrusion damage.

[0060] Further, in this embodiment, a second pressure-sensitive member 611 is provided on one side of the first clamping member close to the second clamping member and / or on one side of the second clamping member close to the first clamping member, and the second pressure-sensitive member 611 is connected to the controller 612 for communication. When the clamping plate 609 clamps the detection device, the surfaces of the two clamping plates 609 close to each other will generate corresponding pressure. The second pressure-sensitive member 611 is provided on the corresponding surface to measure the force of the detection device, so as to avoid the detection device being damaged by excessive force, and also to prevent the detection device from falling due to not being clamped. The two clamping plates 609 are provided with a rubber plate 610 on the surface used for clamping, and a cavity is provided in the rubber plate 610, and the second pressure-sensitive member 611 is provided in the cavity. Since the rubber plate 610 is deformed during the clamping process, the pressure can be transmitted to the second pressure-sensitive member 611 through the rubber plate 610, and the second pressure-sensitive member 611 generates a corresponding signal and transmits the signal to the controller 612, and the controller 612 then regulates the clamping force generated by the clamping plate 609 on the detection device. The rubber plate 610 can increase the maximum friction force between the rubber plate 610 and the detection device, thereby improving the clamping effect. In addition, the rubber plate 610 also protects the second pressure-sensitive member 611, preventing it from being squeezed and damaged by contact with the housing of the detection device.

[0061] Furthermore, the first pressure-sensitive member 607 and the second pressure-sensitive member 611 are both pressure sensors. The pressure sensor may be a sensor of model JHBM-H1, or other models may be used according to actual needs, which is not limited in this embodiment.

[0062] Furthermore, in this embodiment, a mounting frame 602 is provided on the bearing platform 304, and a placing platform 605 is rotatably connected to the mounting frame 602. When the placing platform 605 rotates on the mounting frame 602, it can drive the angle of the detection device clamped by the first clamping member and the second clamping member to change, so as to detect the power distribution system at different heights and facilitate the operator to adjust the viewing angle of the detection device. Specifically, the mounting frame 602 includes two side panels symmetrically arranged on both sides of the rotating plate 601, and a horizontally arranged rotating rod 603 is rotatably connected between the two side panels. The placing platform 605 is arranged on the rotating rod 603, and the rotating rod 603 passes through at least one side panel, and the user can realize the rotation of the placing platform 605 by rotating the end of the rotating rod 603. Furthermore, a rotation drive motor 604 is provided on one of the side panels, and the output end of the rotation drive motor 604 is fixedly connected to the rotating rod 603 to drive the rotating rod 603 to rotate. Furthermore, a reinforcing rib 6031 is extended perpendicularly to the axial direction of the rotating rod 603 , and the reinforcing rib 6031 increases the contact area between the rotating rod 603 and the bottom of the placement table 605 , and strengthens the structural strength of the rotating rod 603 , so as to better fix the placement table 605 .
