Description

Technical Field

[0001] The invention relates to the field of electric power technology, and in particular to an insulator string detection device. Background Art

[0002] Insulators with zero potential difference at both ends of the insulator string in operation are called zero-value insulators. In layman's terms, once the zero-value phenomenon occurs, it means that the insulator has been broken down, the resistance value is zero, and it can no longer play an insulating role, which will seriously affect the safe operation of electricity. Therefore, it is necessary to regularly inspect the insulators in operation to prevent the occurrence of zero-value insulators in advance.

[0003] The detection of zero-value insulators has always been an important part of many power safety operation detection projects, especially the live detection of zero-value insulators on overhead lines, which is directly related to the safety and stability of power transmission. At present, the ground potential operation method is used to carry out live detection of insulator strings. Usually, operators carry insulating operating rods to climb the tower to the designated position and detect the insulator string piece by piece from the conductor side to the cross arm side. During the detection, the operator holds the insulating operating rod and touches the metal wire at the end of the insulating operating rod to both ends of the insulator at the same time. The voltage distributed on the insulator string causes spark gap discharge to verify whether the insulator is broken down.

[0004] This manual detection method is not only time-consuming and labor-intensive, but also poses great safety risks.

In contrast, when a component is referred to as being “directly on another component,” “directly connected to,” “directly coupled to,” or “directly contacting” another component, there are no intervening components present.

[0060] In addition, the accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted.

[0061] The embodiment of the present disclosure provides an insulator string detection device, which can automatically detect each insulator on the insulator string one by one, thereby detecting zero-value or low-value insulators. Figure 1 As shown, the insulator string detection device comprises:

[0062] Two side clamping jaw assemblies 1 arranged along a first direction AA';

[0063] The first driving mechanism 10 matched with the clamping jaw assemblies 1 on both sides is configured to be controlled to drive the clamping jaw assemblies 1 on both sides to move along the first direction AA' to adjust the spacing;

[0064] The clamping jaw assembly 1 on each side comprises:

[0065] The two side clamping structures 100 are arranged along the second direction BB', each side clamping structure 100 includes a support portion 110 and a clamping portion 120, the clamping openings 12a of the clamping portions 120 of the two side clamping structures 100 are arranged facing each other along the second direction BB', and the inner side of the clamping openings 12a is provided with a detection terminal 130, and the second direction BB' is perpendicular to the first direction AA';

[0066] The second driving mechanism 20 connected to the supporting parts 110 of the clamping structures 100 on both sides is configured to drive the clamping parts 120 of the clamping structures 100 on both sides to move toward each other to a clamped state and away from each other to an open state through the supporting parts 110 under control.

[0067] During the inspection, the left clamping jaw assembly 1a and the right clamping jaw assembly 1b along the first direction AA′ are clamped on two adjacent metal caps through their respective clamping jaw portions 120, and the insulator zero measurement task is performed at this time.

[0068] In the next step, combine Figure 2 As shown, the left clamping jaw assembly 1a is kept clamped on the current metal cap J1 through the clamping jaws 120 on both sides, and then the second driving mechanism 20 on the same side as the right clamping jaw assembly 1b is controlled to drive the clamping jaws 120 on both sides of the right clamping jaw assembly 1b to open, and then the first driving mechanism 10 is controlled to drive the right clamping jaw assembly 1b to move forward from the position of the next metal cap J2 to the position of the front metal cap J3 along the first direction AA'. At this time, since the clamping jaws 120 of the right clamping jaw assembly 1b are in an open state, the right clamping jaw assembly 1b can be prevented from being interfered by the insulator during the movement. Then the second driving mechanism 20 on the same side is controlled to drive the clamping jaws 120 on both sides of the right clamping jaw assembly 1b to move toward each other to clamp the front metal cap J3.

[0069] Next, the second driving mechanism 20 on the same side is controlled to drive the two side clamping parts 120 of the left clamping assembly 1a to open, and then the first driving mechanism 10 is controlled to drive the left clamping assembly 1a to move forward along the first direction AA' from the current position of the metal cap J1 to the position of the next metal cap J2, and then the second driving mechanism 20 on the same side is controlled to drive the two side clamping parts 120 of the left clamping assembly 1a to move toward each other to clamp the next metal cap J2.

[0070] Finally, the insulator zero measurement task is started to detect whether the insulator is at a low value or zero value.

[0071] As described above, by repeating the above operation control process, the insulator string detection device of this embodiment is continuously moved along the insulator string to realize the inspection of each insulator on the insulator string one by one, so as to detect all insulators with zero value or low value.

[0072] As can be seen from the above, the insulator string detection of this embodiment has a high degree of automation, and the entire detection process can be completed by controlling the first drive mechanism 10 and the second drive mechanism 20, which greatly saves manual operations and improves the safety and detection efficiency of the insulator string detection.

[0073] In the embodiments of the present disclosure, Figure 3As shown, the components and assemblies in the clamping jaw assembly 1 on each side are assembled together, for example, in the clamping jaw assembly 1 on each side, the clamping jaw structures 100 on both sides and the second driving mechanism 20 (which are encapsulated and cannot be fully visible) are assembled through the first supporting structure 2, and the first supporting structure 2 provides support and installation functions. In this way, the clamping jaw assembly 1 on each side is driven by the first supporting structure 2, and the whole moves synchronously along the first direction AA'.

[0074] In the embodiments of the present disclosure, Figure 1 As shown, the first driving mechanism 10 may include:

[0075] The first rotating motor 101 has a first motor output terminal 10a;

[0076] It has a first rotation input end 10b and two first translation output ends 10c ( Figure 1 The first transmission mechanism 102 (the first translation output end on the left side is blocked and invisible) is connected to the first motor output end 10a through the first rotation input end 10b, and is connected to the clamping jaw assemblies 1 on both sides through the first translation output ends 10c at both ends.

[0077] The first transmission mechanism 102 is configured to convert the rotational motion of the first rotation input end 10b into linear motion of the first translation output ends 10c at both ends along the first direction AA′.

[0078] During operation, one side of the clamping jaw assembly 1 is usually fixed on the metal cap, and the other side of the clamping jaw assembly 1 is driven to move along the first direction AA'. For example, when the left side of the clamping jaw assembly 1a is fixed, the first rotary motor 101 is controlled to rotate, the translation of the left first translation output end 10c is restricted, and the right first translation drive end 10c drives the right side of the clamping jaw assembly 1b to perform linear motion.

[0079] Among them, the rotation direction of the first rotating motor 101 determines the linear movement direction of the right-side clamping jaw assembly 1b. Therefore, by controlling the rotation direction of the first rotating motor 101, the linear movement direction of the clamping jaw assembly 1 can be driven to realize the linear movement drive of the single-sided clamping jaw assembly 1a or 1b.

[0080] During operation, by controlling the power on and off of the first rotating motor 101, the rotation direction of the output end, the speed and other parameters, and cooperating with the first transmission mechanism 102, the movement of the jaw assemblies 1 on both sides toward or away from each other is precisely controlled to achieve movement along the insulator string during actual operation, thereby completing automatic movement and detection operations.

[0081] In the embodiment of the present disclosure, the first transmission mechanism 102 is a screw transmission mechanism, comprising:

[0082] The first screw rod 1021 extending along the first direction AA' is divided into a first thread segment and a second thread segment (not marked in the figure) with opposite spiral directions along the first direction AA'. A transmission member 103 is sleeved on the first screw rod 1021. The transmission member 103 is configured to be a translation limiter along the first direction AA'. The transmission member 103 and the first screw rod 1021 are configured to be rotationally transmission matched and sliding matched along the first screw rod 1021. The first rotation input end 10b is formed on the transmission member 103.

[0083] The first sliding members 1022 at both sides are respectively assembled with the first thread segment and the second thread segment through a screw transmission pair, and the first translation output ends 10c at both ends are correspondingly formed on the first sliding members 1022 at both sides.

[0084] In this embodiment, the transmission member 103 serves as the first rotation input end 10b, inputting the rotational motion from the first rotation motor 101. The rotational transmission fit enables the transmission member 103 to transmit the rotational motion to the first screw rod 1021, and the translation fit enables the first screw rod 1021 and the transmission member 103 to slide relative to each other.

[0085] The screw transmission pair is configured such that the first sliding member 1022 on each side is sleeved on the first screw 1021, and is threadedly connected to the corresponding threaded section on the first screw 1021, and is rotationally limited relative to the first screw 1021. In addition, balls may be filled between the first sliding member 1022 and the first screw 1021 to form a ball screw transmission mechanism.

[0086] If the first sliding member 1022 on one side is fixed, the first screw rod 1021 will also move linearly relative to the fixed first sliding member 1022 while rotating, thereby driving the first sliding member 1022 on the other side to move linearly. At this time, since the transmission member 103 is set as a translation limiter, it remains in place during rotation and will not move linearly with the first screw rod 1021, thereby maintaining the assembly stability between the first motor output terminal 10a.

[0087] Furthermore, the first sliding member 1022 on the other side is rotationally limited relative to the first screw rod 1021, so the rotational movement of the first screw rod 1021 is also converted into the linear movement of the first sliding member 1022 on the other side relative to the first screw rod 1021. Since the spiral directions of the forward thread segment and the reverse thread segment are opposite, the linear movement direction of the first sliding member 1022 on the other side relative to the first screw rod 1021 can be the same as the linear movement direction of the first screw rod 1021.

[0088] Refer to the above insulator string detection device operation process, combined with Figure 2As shown, when the left clamping jaw assembly 1a is clamped on the current metal cap J1, when the first rotating motor 101 drives the first screw rod 1021 to rotate, the linear motion of the left first sliding member 1022 is restricted because the left clamping jaw assembly 1a is restricted by the current metal cap J1, while the right clamping jaw assembly 1b is in a free state, so it can move linearly with the right first sliding member 1022 installed therewith under the drive of the first screw rod 1021, and move linearly in the same direction relative to the first screw rod 1021. Conversely, when the right clamping jaw assembly 1b is clamped and the left clamping jaw assembly 1a is opened, the linear motion of the left clamping jaw assembly 1a along the first direction AA' can be controlled.

[0089] In the embodiment of the present disclosure, the first sliding member 1022 on each side is rotationally limited relative to the first screw rod 1021 to achieve the conversion of the rotational motion of the first screw rod 1021 into the linear motion of the first translation output end 10c. The rotational limit can be set as follows: the first transmission mechanism 102 is also provided with a first track 1023 extending along the first direction AA', and the two first sliding members 1022 form a sliding fit with the first track 1023, such as a slide rail and slide groove structure. In this way, the rotational motion of the first sliding member 1022 on each side is limited by the sliding fit with the first track 1023, and then converted into a linear motion along the first track 1023.

[0090] like Figure 1 As shown, the first transmission mechanism 102 is provided with two parallel first rails 1023, which can maintain the movement stability of the clamping jaw assembly 1 and improve the reliability of the operation. This is an example, and the number and position of the first rails can be designed according to the specific installation environment. For example, a first rail is arranged in parallel under the first sliding member 1022, which can also play a role in rotation limitation and linear guidance.

[0091] In the embodiment of the present disclosure, the rotation transmission cooperation and the translation cooperation between the transmission member 103 and the first screw rod 1021 can be set as follows:

[0092] A transmission matching mechanism is provided between the transmission member 103 and the first screw rod 1021, and the transmission member 103 and the first screw rod 1021 are assembled through the transmission matching mechanism. The transmission matching mechanism includes a transmission matching groove rail and a slider, the groove rail or the slider extends along the first direction AA', and the slider can move along the slide rail. On the one hand, the groove rail cooperates with the slider so that the transmission member 103 can drive the first screw rod 1021 to rotate synchronously, and on the other hand, the groove rail cooperates with the slider so that the translation of the first screw rod 1021 will not be transmitted to the transmission member 103, but guides the slider to slide along the groove rail, and the transmission member 103 has no translation along the first direction AA'.

[0093] The groove is formed on the outer circumference of the first screw rod 1021, and the slider is formed on the inner circumference of the transmission member 103, or vice versa.

[0094] In the embodiments of the present disclosure, Figure 1 As shown, the insulator string detection device also includes:

[0095] The support plate 3 , the first rail 1023 and the first rotating motor 101 are all fixed on the support plate 3 to realize the integration of corresponding components. The support plate 3 provides support for the first driving mechanism 10 as a whole.

[0096] In the embodiment of the present disclosure, the first motor output end 10a is connected to the first rotation input end 10b through the first gear transmission mechanism 104. Specifically, the first motor output end 10a is coaxially connected with a first gear 1041, so that the first motor output end 10a is formed on the first gear 1041. A second gear 1042 is set between the two ends of the first screw rod 1021, so that the first rotation input end 10b is formed on the second gear 1042. The first gear 1041 and the second gear 1042 are meshed to form the first gear transmission mechanism 104.

[0097] In combination with the above, the transmission member 103 forms the first rotation input end 10b, and the second gear 1042 is an implementation of the transmission member 103. In this way, the rotational motion output by the first motor output end 10a is transmitted to the first screw rod 1021 through the first gear transmission mechanism 104.

[0098] In the embodiment of the present disclosure, the second gear 1042 is installed in the middle part of the first screw rod 1021, which makes reasonable use of the installation space. In another embodiment, the second gear 1042 can also be installed at any end of the first screw rod 1021, which is not limited here.

[0099] In another embodiment, the first motor output end and the first rotation input end may be connected via a belt transmission mechanism. For example, the first motor output end is coaxially mounted with a driving wheel, the first screw rod is mounted on a driven wheel, and the driven wheel serves as a transmission member, so that the first rotation input end is formed on the driven wheel. A transmission belt is tensioned between the driving wheel and the driven wheel to transmit the rotational motion of the driving wheel to the driven wheel and the first screw rod.

[0100] In this embodiment, the first rotating motor cooperates with a set of first transmission mechanisms to complete the translation of the clamping jaw assemblies on both sides. This structure uses fewer components and has high control accuracy. In an optional embodiment, a set of first drive mechanisms based on a motor-screw transmission mechanism can be provided for each side of the clamping jaw assembly to achieve separate control of the movement of each side of the clamping jaw assembly along the first direction.

[0101] In another optional embodiment, the first driving mechanism may also directly use a linear motor or a translational cylinder or other mechanism to achieve linear movement of the clamping jaw assembly on either side.

[0102] In the embodiment of the present disclosure, an optical acquisition device can be set on the insulator string detection device, and the optical acquisition device can be used to collect the positions of the jaw assemblies on both sides moving toward or away from each other, so as to achieve precise control of the operation of the first driving mechanism (such as the first rotating motor), and finally achieve precise control of the moving positions of the jaw assemblies on both sides.

[0103] The optical acquisition device may be a camera or the like.

[0104] In the disclosed embodiment, the support portion 110 has a free end 11a, a driving end 11b and a fixed end 11c, and the clamping claw portion 120 is mounted on the free end 11a;

[0105] The clamping jaw assembly 1 on each side further includes a fixed support column 140, the support portion 110 is connected to the support column 140 through the fixed end 11c via a first rotating shaft 150, and the first rotating shaft 150 is parallel to the first direction AA';

[0106] The second driving mechanism 20 has two second translation output ends 20a (the left end is blocked and invisible) arranged along the second direction BB′. The second translation output end 20a at each end is rotationally connected to the driving end 11b of the corresponding support part 110 through a first connecting rod 160.

[0107] The second driving mechanism 20 is specifically configured to be controlled to output reverse linear movement along the second direction BB' through the second translation output ends 20a at both ends, so as to convert the reverse linear movement into reverse rotation of the supporting parts 110 on both sides around the corresponding first rotating shaft 150 through the first connecting rod 160, so that the clamping claws 120 on both sides move toward each other to a clamped state and move away from each other to an open state.

[0108] In this embodiment, the second driving mechanism 20 outputs reverse translation along the second direction BB' through the second translation output ends 20a at both ends, including moving toward each other and moving away from each other. Each first connecting rod 160 translates with the second translation output end 20a installed thereon, and rotates around the second translation output end 20a, further driving the driving end 11b to move together. Since the fixed end 11c of the support portion 110 is fixed, the driving end 11b can only rotate around the first rotating shaft 150, thereby driving the free end 11a to rotate synchronously. Since the translation directions of the second translation output ends 20a at both ends are opposite, the rotation directions of the support portions 110 of the clamping structures 100 on both sides are opposite, so that the clamping jaws 120 can move toward each other to the clamped state and move away from each other to the open state.

[0109] In the embodiments of the present disclosure, Figure 1 As shown, the second driving mechanism 20 includes:

[0110] The second rotating motor 201 has a second motor output terminal 20b;

[0111] A second transmission mechanism 202 having a second rotation input end 20c and second translation output ends 20a at two ends, and being transmission-connected to the second motor output end 20b via the second rotation input end 20c;

[0112] The second transmission mechanism 202 is configured to convert the rotation of the second rotation input end 20c into a reverse linear movement of the second translation output ends 20a at both ends along the second direction BB'.

[0113] In this embodiment, the second transmission mechanism 202 is used to convert the rotational motion into linear motion, so that the two clamping jaw structures 100 of the same clamping jaw assembly 1 move synchronously in opposite directions to switch between clamping and opening. In this embodiment, a set of second transmission mechanisms 202 is used to realize the clamping and opening control of the clamping jaw structures 100 on both sides, saving the number of components and improving product integration and reliability.

[0114] In the embodiment of the present disclosure, the second transmission mechanism 202 is a screw transmission mechanism, comprising:

[0115] A second screw rod 2021 extending along the second direction BB' is divided into a third thread segment and a fourth thread segment having opposite spiral directions along the second direction BB', and a second rotation input end 20c is formed on the second screw rod 2021;

[0116] The second sliding members 2022 on both sides are assembled with the third thread segment and the second thread segment through a screw transmission pair, each second sliding member is connected to the first connecting rod 160 on the corresponding side, and the second translation output ends 20a at both ends are correspondingly formed on the second sliding members 2022 on both sides.

[0117] In this embodiment, the screw transmission pair is configured such that two second sliding members 2022 are sleeved on the second screw 2021 and are threadedly connected to the threaded segments on the corresponding sides. At the same time, the second sliding members 2022 are rotationally limited so that the rotational motion of the second screw 2021 can be converted into linear motion of the two second sliding members 2022.

[0118] Since the third and fourth thread segments have opposite spiral directions, when the second screw rod 2021 rotates, the two second sliding members 2022 move in opposite directions along the second direction BB'. In this way, by controlling the second screw rod 2021 to rotate in opposite directions, the second sliding members 2022 on both sides can move toward or away from each other, and further synchronously realize the opposite rotation of the clamping jaw structures 100 on both sides to achieve a clamped state or an open state.

[0119] Therefore, by controlling the second rotary motor 201 to rotate forward and reverse, the rotation direction of the second screw rod 2021 can be changed, and finally the clamping and separation of the two side clamping jaws 120 can be achieved. In this embodiment, the accuracy of the electrical signal control is relatively high.

[0120] In the embodiment of the present disclosure, the rotation limit of the second sliding member 2022 on each side can be set as follows: the second transmission mechanism 202 also includes a second track 2023 arranged in parallel with the second screw rod 2021 and below the second screw rod 2021, and each second sliding member 2022 forms a sliding fit with the second track 2023, such as a slide rail and slide groove structure. In this way, the rotational movement of each second sliding member 2022 is limited by the second track 2023, and then converted into a linear motion along the second track 2023.

[0121] In another embodiment, the second track may not be provided. For example, the bottom surface of each second sliding member is a plane or other irregular shape, which cooperates with the surface of the base below to achieve rotation limitation.

[0122] In the embodiments of the present disclosure, Figure 1 As shown, the second rotation input end 20c of the second screw rod 2021 is connected to the second motor output end 20b through the second gear transmission mechanism 203. Specifically, a driving gear 2031 is coaxially connected to the second motor output end 20b, and a driven gear 2032 is coaxially connected to one end of the second screw rod 2021, and the driving gear 2031 and the driven gear 2032 are meshed to form the second gear transmission mechanism 203. In this way, the second motor output end 20b is formed on the driving gear 2031, the second rotation input end 20c is formed on the driven gear 2032, and the rotational motion output by the second rotating motor 201 is transmitted to the second screw rod 2021 through the second gear transmission mechanism 203.

[0123] In another embodiment, the second rotary motor 201 and the second screw rod 2021 may be connected via a belt transmission mechanism. For example, the output end of the second motor is coaxially connected to the driving wheel, the second screw rod is coaxially connected to the driven wheel, and a transmission belt is tensioned between the driving wheel and the driven wheel to transmit the rotational motion of the driving wheel to the driven wheel and the second screw rod.

[0124] In an optional embodiment, the gear transmission mechanism or the belt transmission mechanism may not be provided, but the second motor output end is directly coaxially connected with the second screw rod to achieve synchronous rotation. These embodiments can be selected according to the specific installation environment and are not limited here.

[0125] In an optional embodiment, the second transmission mechanism may not be provided, and a second rotary motor may be connected to the first rotating shaft of the support portion to directly drive the support portion to rotate around the first rotating shaft.

[0126] These implementation methods can be designed according to specific application scenarios and installation environments.

[0127] In an optional embodiment, a linear motor or a translation cylinder or other driving mechanism is used to replace the second driving mechanism in this embodiment. For example, the linear motor directly outputs linear motion through the linear output end, and the support part and its clamping claw part can be driven to rotate through the first connecting rod. In this case, a linear motor and a first connecting rod can be set corresponding to each clamping claw structure, and the linear motors on both sides can be synchronously controlled to synchronously output the movement toward or away from each other.

[0128] In this embodiment, the second rotating motor cooperates with a set of second transmission mechanisms to complete the clamping and opening of the clamping structures on both sides. In an optional embodiment, a set of second drive mechanisms based on a motor-screw transmission mechanism can also be set corresponding to each side of the clamping structure to achieve separate control of the rotation of each side of the clamping structure.

[0129] In an optional embodiment, a linear motor or a translation cylinder may be provided corresponding to each side of the clamping jaw structure to replace the second driving mechanism based on the first connecting rod. For example, the translation output end of the linear motor is fixedly connected to the support portion of the corresponding clamping jaw structure, and the linear motor drives the support portion and its clamping jaw portion to perform linear motion along the first direction, so as to achieve linear movement of the clamping jaw portions on both sides of the same clamping jaw structure toward each other or away from each other.

[0130] Combination Figure 1 and Figure 3 The support column 140 on each side provides support for the clamping jaw structure 100 on the same side. The support column 140 and the first support structure 2 ( Figure 1 The second support structure 170 is fixedly connected to the first support structure 2 (not shown), and has the function of installing and supporting the second drive mechanism 20 and the clamping claw structure 100 on the same side. Specifically, the second support structure 170 is a hollow structure, and the second drive mechanism 20 is encapsulated in the first support structure 2. The second support structure 170 reserves an opening for the clamping claw structure 100 to rotate.

[0131] like Figure 1 As shown, the first rotating shaft 150 passes through the fixed end 11 c of the supporting portion 110 and is fixedly connected to the top end of the supporting column 140 , so that the supporting portion 110 can rotate around the first rotating shaft 150 .

[0132] In this embodiment, the support portion 110 includes a first rib 111, a second rib 112 and a third rib 113; the first rib 111 and the second rib 112 are connected to the free end 11a, the first rib 111 and the third rib 113 are connected to the driving end 11b, and the second rib 112 and the third rib 113 are connected to the fixed end 11c;

[0133] The fixed end 11c of the support portion 110 is closer to the other side of the clamping structure 100 than the driving end 11b along the second direction BB′. The first connecting rod 160 connects the driving end 11b and the second translation output end 20a of the support portion 110 located on the same side along the second direction BB′.

[0134] In this embodiment, in each support portion 110, the second rib 112 and the first rib 111 are connected to the free end 11a, and the free end 11a is used to connect the clamping jaw portion 120. The surface of the second rib 112 facing away from the first rib 111 is a concave slope extending from the free end 11a to the fixed end 11c. In this way, in the same clamping jaw assembly 1 (for example, the left clamping jaw assembly 1a), when the clamping jaw structures 100 on both sides are in the open state, the second ribs 112 of the clamping jaw structures 100 on both sides form a larger surrounding space, which is suitable for avoiding insulators of various sizes during the forward movement of the insulator string detection device to ensure operation reliability.

[0135] The sizes of insulators on the insulator strings in different scenarios vary greatly. For example, the above-mentioned concave slope surface of the second rib 112 can be an elliptical arc surface, and the free end 11a can be located at the long axis end of the ellipse or near it. In this way, in the same clamping jaw assembly 1, the free ends 11a on the supporting parts 110 on both sides are roughly located at or near the two long axis ends of the same ellipse, so that the second ribs 112 on both sides of the same clamping jaw assembly 1 form a relatively larger embracing space, which also makes the space size between the second ribs 112 on both sides of the same clamping jaw assembly 1 have a larger adjustment range, so that in the process of moving the insulator string detection device forward, it is better suitable for avoiding insulators of various sizes, so as to improve the adaptability of the insulator string detection device to the scene.

[0136] In an optional implementation, the first connecting rod may connect the clamping jaw structure and the second translation output end located on different sides along the second direction, which is not limited here.

[0137] In the embodiment of the present disclosure, an elastic pad 121 is disposed inside the jaw opening 12a, which fits tightly with the surface of the metal cap when the jaw portion 120 clamps the metal cap, providing good clamping force. The elastic pad 121 is made of silicone or rubber, and provides good clamping force by selecting a suitable hardness.

[0138] In the embodiment of the present disclosure, the surface of the elastic pad 121 is set as an inclined surface extending along the first direction AA', or a step structure distributed along the first direction AA'. For metal caps of various sizes and shapes, the step structure can ensure that there are at least two line contacts with the metal cap, and the inclined surface can also ensure that there is at least a line contact between it and the metal cap to ensure the clamping force.

[0139] In the embodiment of the present disclosure, the detection terminal 130 disposed inside the jaw opening 12a serves as an insulator zero detection motor. A detection contact (not shown in the figure) is also disposed inside the jaw opening 12a to detect whether the jaw portion 120 contacts the metal cap.

[0140] Specifically, the detection contact sleeve is provided with a spring, and after contacting the metal cap, the spring is squeezed and elastically moves backward. The elastic backward movement will be detected by an optical coupler arranged below the other end of the detection contact. In the clamping step, when the optical coupler is triggered and the second rotating motor is blocked, it can be determined that the clamping claw part has embraced the metal cap. The clamping is determined only when the above two conditions are met, so as to improve the accuracy and avoid the motor being blocked after the clamping claw touches a foreign object and is mistakenly judged as clamping the metal cap.

[0141] In the embodiments of the present disclosure, Figure 3 As shown, in the clamping jaw assembly 1 on each side, the clamping jaw structures 100 on both sides and the second driving mechanism 20 are assembled in the first supporting structure 2;

[0142] Combination Figure 4 As shown, the clamping jaw assembly 1 on each side further includes: a third driving mechanism 30 and a second supporting structure 170 assembled with the third driving mechanism 30;

[0143] The first driving mechanism 10 cooperates with the second supporting structures 170 on both sides, and is configured to be controlled to drive the clamping jaw assemblies 1 on both sides to move along the first direction AA' through the second supporting structures 170 on both sides to adjust the spacing;

[0144] The second support structure 170 is rotatably assembled with the first support structure 2 via a second rotation axis 180 , and the second rotation axis 180 is parallel to the second direction BB′;

[0145] The third driving mechanism 30 forms a driving cooperation with the first supporting structure 2 and is configured to controllably drive the first supporting structure 2 to drive the clamping structure 100 to rotate around the second rotating shaft 180 to adjust the inclination angle of the clamping assembly 1 compared to the clamping assembly 1 on the other side.

[0146] like Figure 3As shown, in the insulator string, due to gravity or the inclination caused by the line trend, two adjacent metal caps are not on the same horizontal line. For example, the next metal cap may be at a position lower than or higher than the current metal cap. At this time, if the corresponding clamping jaw assembly 1 at the current metal cap is operated to move to the next metal cap along the first direction AA', the clamping jaw assembly 1 may conflict with the adjacent insulator or the next metal cap during the forward movement, resulting in failure to move normally to the clamping position of the next metal cap. It is also possible that even if the clamping jaw assembly 1 moves to the position of the next metal cap, the middle area of ​​the metal cap exceeds the clamping space between the clamping jaws 120 on both sides, and the clamping jaws 120 on both sides cannot reliably grip the metal cap.

[0147] Using the detection device of this embodiment, combined with Figure 2 As shown, before the right clamping jaw assembly 1b is moved forward, the third driving mechanism 30 on the left side can be controlled to drive the left clamping jaw assembly 1a to rotate. Since the left clamping jaw assembly 1a clamps the current metal cap J1 and cannot move, its rotation trend is converted to the second support structure 170 (reference Figure 4 ), and the rotation of the second support structure 170 is synchronously transmitted to the first driving mechanism 10 and the right clamping jaw assembly 1b, and finally drives the right clamping jaw assembly 1b to rotate, such as Figure 2 As shown, it is rotated downward, thereby ensuring that the subsequent forward movement of the right clamping jaw assembly 1b can avoid the metal cap J2.

[0148] In actual operation, the left clamping jaw assembly 1a is fixed, the first rotary motor 101 is controlled to rotate, the translation of the left first translation output end 10c is restricted, and the right first translation drive end 10c drives the right clamping jaw assembly 1b to move linearly. Then, when the right clamping jaw assembly 1b in front moves, its clamping jaw part 120 is in a relatively low position compared to the left clamping jaw assembly 1a in the back, so that the right clamping jaw assembly 1b can avoid the collision with the metal cap J2, and then reach the position of the front metal cap J3 along a straight line.

[0149] After that, the third driving mechanism 30 on the left side is controlled to drive the left clamping jaw assembly 1a to rotate in the opposite direction. Since the left clamping jaw assembly 1a clamps the current metal cap J1 and cannot move, its reverse rotation trend is converted into the second supporting structure 170 (reference Figure 4 ), and the reverse rotation of the second support structure 170 is synchronously transmitted to the first driving mechanism 10 and the right clamping jaw assembly 1b, and finally drives the right clamping jaw assembly 1b to rotate upward in the reverse direction until the front metal cap J3 is located in the clamping space between the two side clamping jaws 120. Finally, the clamping operation of the front metal cap J3 is performed.

[0150] When moving the left jaw assembly 1a forward in the next step, you can refer to the rotation process of the right jaw assembly 1b, and drive the left jaw assembly 1a to rotate downward by controlling the third driving mechanism 30 on the same side as the right jaw assembly 1b, and then control it to move forward, rotate upward in the opposite direction, and clamp the next metal cap J2.

[0151] Therefore, the third driving mechanism 30 on each side is connected to the second supporting structure 170 (refer to Figure 4 ) to cooperate with each other to adjust the inclination of the clamping structure 100 of the clamping assembly 1 on the other side, which can improve the feasibility of automated operation.

[0152] In another practical scenario of insulator string application, such as Figure 5 As shown, in the actual installation scenario of the insulator string, due to gravity or the inclination caused by the line trend, the first metal cap 5a, the second metal cap 5b and the third metal cap 5c are gradually downward in an arc. Figure 5 In the given example, the absolute value of the slope at the first metal cap 5a is greater than the absolute value of the slope at the second metal cap 5b; the absolute value of the slope at the second metal cap 5b is greater than the absolute value of the slope at the third metal cap 5c.

[0153] During the process of the insulator string detection device moving from between the first metal cap 5a and the second metal cap 5b to between the second metal cap 5b and the third metal cap 5c, since the absolute value of the slope at the first metal cap 5a is greater than the absolute value of the slope at the second metal cap 5b, and the absolute value of the slope at the second metal cap 5b is greater than the absolute value of the slope at the third metal cap 5c, if the insulator string detection device continues to maintain the inclination when clamped between the first metal cap and the second metal cap and moves toward the third metal cap, the right-side clamping jaw assembly may be lower than the middle area of ​​the third metal cap, thereby risking not clamping the third metal cap 5c. In order to ensure that the right-side clamping jaw assembly 1b reliably grasps the metal caps, during or after the right-side clamping jaw assembly 1b is moved forward, the third driving mechanism 30 on the left side is controlled to drive the right-side clamping jaw assembly 1b to rotate upward, so as to ensure that the middle area of ​​the third metal cap 5c is located within the clamping space of the right-side clamping jaw assembly 1b. Figure 5 As shown, the front end of the insulator string detection device pointed by the arrow has an upward angle compared to the rear end.

[0154] In addition, during the process of the right clamping jaw assembly 1b moving from the second metal cap 5b to the third metal cap 5c, the clamping jaw portion 120 of the right clamping jaw assembly 1b is kept in the maximum open state to avoid the insulator 5d. After the middle area of ​​the third metal cap 5c is located in the clamping space of the right clamping jaw assembly 1b, the clamping jaw portion 120 of the right clamping jaw assembly 1b is closed to firmly grasp the third metal cap 5c. Subsequently, the left clamping jaw assembly 1a moves from the first metal cap 5a to the second metal cap 5b, thereby realizing the forward movement of the insulator string detection device.

[0155] Continuing, in the embodiments of the present disclosure, if Figure 4 As shown, the second supporting structure 170 is used to support the third driving mechanism 30 , and is also provided with a front protrusion 171 , which is rotatably connected to the second rotating shaft 180 .

[0156] Combination Figure 3 As shown, the first supporting structure 2 is provided with two columns 21 and 22 which are arranged opposite to each other along the second direction BB′. The second rotating shaft 180 is arranged between the two columns 21 and 22 and is fixedly mounted to the two columns 21 and 22 .

[0157] Figure 3 One implementation is shown. In another implementation, the rotation can be realized according to the expectation of the final rotation. Figure 3 The structure shown is improved accordingly.

[0158] For example Figure 3 As shown, the insulator string detection device is also provided with a support plate 3, and the first drive mechanism 10 is fixed on the support plate 3. The support plate 3 supports the first drive mechanism 10 and further provides support for the second support structure 170 and the third drive mechanism 30 thereon and the clamping jaw assembly 1.

[0159] In the embodiments of the present disclosure, Figure 4 and 2 As shown, in each side clamp structure 100, the third driving mechanism 30 has a third translation output end 30a, the third translation output end 30a is connected to the first support structure 2 through a second connecting rod 190, the second connecting rod 190 is rotationally connected to the first support structure 2 through a third rotating shaft 200, the second rotating shaft 180 and the third rotating shaft 200 are arranged in parallel, for example, the second rotating shaft 180 is located below the third rotating shaft 200, and the second connecting rod 190 is perpendicular to the second direction BB';

[0160] The third driving mechanism 30 is specifically configured to be controlled to output a linear movement along the first direction AA' through the third translational output end 30a, so as to convert the linear movement into a rotation of the first supporting structure 2 around the second rotating axis 180 through the second connecting rod 190, so as to drive the clamping structure 100 to rotate around the second rotating axis 180, so as to adjust the inclination angle of the clamping assembly 1 compared to the clamping assembly 1 on the other side.

[0161] In this embodiment, if Figure 2As shown, the third driving mechanism 30 outputs a translational motion along the first direction AA'. Since the second rotating shaft 180 is fixed by the first supporting structure 2, it cannot move, so that the translational motion of the first supporting structure 2 is restricted. Therefore, the translational motion output by the third driving mechanism 30 will not cause the translational motion of the first supporting structure 2 and the clamping structure 100 assembled therewith, but is converted into a rotation of the first supporting structure 2 and the clamping structure 100 assembled therewith around the second rotating shaft 180 through the second connecting rod 190, thereby adjusting the inclination angle of the right-side clamping assembly 1b compared to the left-side clamping assembly 1a.

[0162] In the embodiments of the present disclosure, Figure 4 As shown, the third driving mechanism 30 includes:

[0163] The third rotating motor 301 has a third motor output terminal 30b;

[0164] A third transmission mechanism 303 having a third rotation input end 30c and a third translation output end 30a, which is transmission-connected to the third motor output end 30b via the third rotation input end 30c to input rotational motion;

[0165] The third transmission mechanism 303 is configured to convert the rotational motion of the third rotation input end 30c into the linear motion of the third translation output end 30a along the first direction AA′.

[0166] In this embodiment, the third transmission mechanism 303 is used to convert the rotational motion into a linear motion, so that the third translation output end 30a outputs a translation, and finally converts the translation into the clamping jaw structure 100 (such as Figure 2 rotation as shown).

[0167] In the embodiment of the present disclosure, the third transmission mechanism 303 is a screw transmission mechanism, comprising:

[0168] A third screw rod 3031 extending along the first direction AA′, and a third rotation input end 30c is formed on the third screw rod 3031;

[0169] The third sliding member 3032 is assembled with the third screw rod 3031 through a screw rod transmission pair, and the third translation output end 30 a is formed on the third sliding member 3032 .

[0170] In this embodiment, the screw transmission pair is configured such that the third sliding member 3032 is sleeved on the third screw rod 3031 and is threadedly connected to the third screw rod 3031 , and the third sliding member 3032 is rotationally limited, so that the rotational motion of the third screw rod 3031 can be converted into the linear motion of the third sliding member 3032 .

[0171] In the embodiment of the present disclosure, the rotation limit of the third sliding member 3032 can be set as follows: the third transmission mechanism 303 also includes a third track 3033 arranged in parallel with the third screw rod 30331 and below the third screw rod 3031, and the third sliding member 3032 and the third track 3033 form a sliding fit, such as a slide rail and slide groove structure. In this way, the rotational movement of the third sliding member 3032 is limited by the third track 3033, and then converted into a linear motion along the third track 3033.

[0172] In another embodiment, the third track may not be provided. For example, the bottom surface of the third sliding member is a plane or other irregular shapes, which cooperates with the surface of the base below to achieve rotation limitation.

[0173] In the embodiment of the present disclosure, the third rotation input end 30c of the third screw rod 3031 is connected to the third motor output end 30b via the third gear transmission mechanism 304. Specifically, a main gear 3041 is coaxially connected to the third motor output end 30b, and a slave gear 3042 is coaxially connected to one end of the third screw rod 3031. The main gear 3041 and the slave gear 3042 are meshed to form the third gear transmission mechanism 304. In this way, the rotational motion output by the third rotating motor 301 is transmitted to the third screw rod 3031 through the third gear transmission mechanism 304.

[0174] In another embodiment, the third rotating motor and the third screw rod may be connected via a belt transmission mechanism.

[0175] In an optional embodiment, the gear transmission mechanism or the belt transmission mechanism may not be provided, but the output end of the third motor is directly coaxially connected with the third screw rod to achieve synchronous rotation. These embodiments can be selected according to the specific installation environment and are not limited here.

[0176] In an optional implementation, the third transmission mechanism may not be provided, and a third rotary motor may be connected to the second rotating shaft to directly drive the first supporting structure to rotate around the second rotating shaft.

[0177] These implementation methods can all be designed according to specific application scenarios and installation environments.

[0178] In an optional embodiment, a linear motor or a translational cylinder or other driving mechanism is used to replace the third driving mechanism in this embodiment. For example, the linear motor directly outputs linear motion and can drive the first supporting structure and its upper clamping structure to rotate through the second connecting rod.

[0179] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
