Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electrical transmission, and in particular relates to a puncture type grounding hanging ring and a remote control installation device thereof. BACKGROUND

[0002] With the rapid development of social economy, the dependence on power supply is increasing day by day, and the scale of power grid continues to expand, and the pressure of power equipment operation and maintenance is increasingly severe. In the maintenance operation of distribution network, safety is the primary prerequisite. At present, overhead insulated conductors are widely used in distribution network lines, which undoubtedly improves the reliability of power supply during normal operation, but introduces new safety risks during maintenance: the traditional grounding clamp cannot effectively penetrate the insulating layer of the conductor, resulting in too large grounding loop resistance and unable to form a reliable equipotential connection, so that the maintenance personnel are threatened by electric shock due to line reverse power or induced current.

[0003] To solve this safety problem, installing a puncture type grounding hanging ring on the insulating conductor has become a standard operating procedure. The hanging ring directly contacts the metal core of the conductor through the puncture teeth, providing a permanent and reliable connection point for subsequent grounding wire connection.

[0004] However, the current installation method of the puncture type grounding hanging ring itself has significant limitations, which has become a bottleneck of operation efficiency and safety. First, the manual tower climbing method requires the operator to carry tools and climb the tower, and manually install in the air. This method not only has high labor intensity and low efficiency, but more importantly, it directly exposes the workers to the double risks of high-altitude falling and potential electric shock in a complex environment without complete electric verification. Second, mechanical arm assisted installation, although it avoids personnel climbing, but the existing mechanical arm is a general type device, and its end effector is not specially designed for the puncture type grounding hanging ring. There are problems such as cumbersome operation, poor positioning accuracy, and inaccurate clamping force control. It is easy to cause the hanging ring to be not tightly installed, the contact resistance to be high, or the insulating layer of the conductor to be damaged during installation, which poses a hidden danger to the long-term operation of the line. In addition, its high cost and complex operation also limit its popular application in distribution sites.

[0005] Therefore, there is an urgent need in the art for a special puncture type grounding hanging ring installation device and method that can realize accurate and reliable installation and cost control, in order to fundamentally improve the safety and modernization level of distribution maintenance operation.

Therefore, the features defined with "first", "second" and the like can be explicitly or implicitly included one or more. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0025] In the description of the present application, it needs to be understood that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0026] The present application will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0027] As Figure 1 shown, a puncture type grounding hanging ring, comprising: a fixed clamping arm 41, composed of a first body 412 and a clamping ring 5 rotatably connected with the first body 412, a first clamping tooth 451 is arranged on the inner side of the first body 412, and a grounding interface 51 is arranged on the clamping ring 5; a movable clamping arm 42, comprising a second body 422, a second clamping tooth 452 is arranged on the inner side of the second body 422; a guide structure 43, which movably connects the fixed clamping arm 41 and the movable clamping arm 42; a temporary locking mechanism is arranged between the fixed clamping arm 41 and the movable clamping arm 42; the temporary locking mechanism is provided with a first interface 411 for mounting the fixed clamping arm 41 and a second interface 421 for mounting the movable clamping arm 42; wherein the opposite inner sides of the first body 412 and the second body 422 are provided with a clamping structure, and a clamping space for accommodating the wire is formed between them.

[0028] Specifically, the temporary locking mechanism temporarily fixes the movable clamping arm and the fixed clamping arm before installation, realizing pre-installation. In addition, the clamping ring is in electrical communication with the fixed clamping arm, and when the piercing grounding hanging ring is in electrical communication with the wire, the clamping ring also realizes electrical communication with the wire; the grounding interface 51 is arranged on the clamping ring, and when needed, the worker only needs to connect the wire with the interface, so that the grounding operation can be quickly and reliably completed. The arrangement of the component simplifies the process of subsequent grounding operation, making the entire maintenance operation more standard and convenient.

[0029] As shown in Figure 1 , the vertical section of the first body 412 is in a "C" type structure; the structure of the second body 422 cooperates with the first body 412.

[0030] Specifically, the "C" type first body forms a semi-closed structure with a side wall, which has the function of a guide groove. This design not only facilitates the positioning of the wire but also prevents the wire from slipping, greatly reducing the difficulty of positioning in high-altitude operation; the design of the first body and the second body cooperating with each other effectively guides the clamping force to the center, ensuring the precision of the clamping action and the stability of the structure after clamping.

[0031] As shown in Figure 1 , the first clamping tooth 451 and the second clamping tooth 452 are in meshing relationship; the tooth shape of the first clamping tooth 451 and / or the second clamping tooth 452 is unidirectional sawtooth shape, arc shape or trapezoidal shape.

[0032] Specifically, the design of the tooth shape, especially the unidirectional sawtooth shape, guarantees the final locking and electrical connection, ensuring the permanent reliability of the connection.

[0033] As shown in Figure 1 , the guide structure 43 is a guide shaft arranged on the inner side of the first body 412, and the second body 422 is provided with a guide hole 431 cooperating with the guide shaft.

[0034] Specifically, the design of the guide shaft and the guide hole not only offsets the lateral component force in the clamping process, but also prevents the movable clamping arm from tilting, being stuck or being misaligned with the fixed clamping arm, ensuring the quality of clamping.

[0035] As shown in Figure 1 , the temporary locking mechanism includes a first buckle assembly 441 arranged on the outer side of the first body 412 and a second buckle assembly 442 arranged on the outer side of the second body 422 and cooperating with the first buckle assembly 441.

[0036] Specifically, the buckle assembly realizes the pre-installation between the fixed clamping arm and the movable clamping arm, and during transportation and lifting, the buckle assembly firmly locks the movable clamping arm and the fixed clamping arm into a whole, avoiding the risk of accidental opening.

[0037] As shown in Figure 1 the first buckle assembly 441 includes a buckle strip 443, and the buckle strip is provided with a protrusion 444; the second buckle assembly 442 includes a buckle hole 445; when the buckle strip 443 is inserted into the buckle hole 445, the protrusion 444 is embedded in the buckle hole 445 and is clamped with the inner wall of the buckle hole 445; the protrusions 444 are distributed at intervals along the buckle strip 443.

[0038] Specifically, the multi-protrusion buckle assembly provides adjustable temporary locking force, and the protrusions distributed at intervals along the buckle strip substantially create multiple selectable locking positions, so that the movable clamp arm can be fixed at different opening degrees according to different wires, thereby improving the adaptability of the device.

[0039] As shown in Figure 1 the first interface 411 includes a magnetic adsorption structure and is arranged on the first buckle assembly 441; the second interface 421 includes a clamping groove and is arranged on the second buckle assembly 442.

[0040] Specifically, the arrangement of the interface facilitates the assembly of the puncture type grounding lug and the remote control installation device, and facilitates the disengagement of the puncture type grounding lug from the remote control installation device.

[0041] In addition, as a preferred embodiment, the first body is provided with a sealing rubber ring, and the sealing rubber ring is pre-filled with silicone grease.

[0042] Specifically, the sealing rubber ring and the silicone grease are not specifically marked in the drawings, but when the first clamping tooth and the second clamping tooth are engaged, this structure naturally forms a cavity wrapping the wire, and the addition of the sealing ring further enhances the moisture-proof sealing performance of the structure. The sealing rubber ring will elastically deform when subjected to pressure, tightly fit around the puncture position, and prevent external moisture and impurities from entering. The silicone grease fills the puncture gap after overflowing, further enhancing the sealing and waterproof performance, ensuring that the puncture type grounding lug and the wire are connected stably and reliably in a long-term outdoor environment, and preventing water erosion and other problems from affecting the electrical performance.

[0043] As shown in Figures 2 to 7As shown, a remote control installation device comprises: the above-mentioned puncture type grounding eye; a shell 1; a driving unit integrated in the shell 1, comprising a power source 21 and a driving mechanism 22 electrically connected with the power source 21; a control unit integrated in the shell 1, comprising a control module 31 and a remote control module 32 and a pressure sensing module in communication connection with the control module 31; the control unit is electrically connected with the driving unit; the fixed clamping arm 41 is detachably installed on the head 14 of the shell 1 through the first interface 411; the movable clamping arm 42 is drivingly connected with the output end 221 of the driving mechanism 22 through the second interface 421.

[0044] Specifically, the control module is configured to: receive a start instruction through the remote control module, respond to the start instruction, control the driving mechanism to work, and drive the output end of the driving mechanism to drive the movable clamping arm to perform a preset mechanical movement, so that the eye unit performs a clamping action; after receiving the feedback signal of the pressure sensor module, the control module judges whether the clamping action reaches a preset completion condition according to the feedback signal, and controls the driving mechanism to stop working when the completion condition is met.

[0045] As a preferred embodiment, the control module realizes precise control by the following steps: continuously reading the real-time pressure value monitored by the pressure sensing module; comparing the real-time pressure value with a preset safe locking pressure threshold value; when the real-time pressure value reaches or exceeds the pressure threshold value, immediately cutting off the power supply of the driving mechanism to stop its movement, so as to ensure that the eye unit clamps the wire with the best locking force, which not only ensures reliable connection, but also avoids damaging the wire.

[0046] When the puncture type grounding eye is installed on the remote control installation device, the fixed clamping arm and the movable clamping arm are first connected through the guide structure and the temporary locking mechanism, then the first interface on the fixed clamping arm is connected with the head of the installation device, and the second interface on the movable clamping arm is connected with the output end of the driving mechanism. In this way, the movable clamping arm can move relative to the fixed clamping arm under the drive of the driving mechanism, so as to switch the eye unit between the open state and the closed state.

[0047] During the whole installation process, the guide shaft and the buckle assembly work together to effectively ensure the smooth installation. In the pre-installation stage, the operator selects the appropriate protrusion position on the buckle strip according to the thickness of the wire, and manually locks the hanging ring unit in the appropriate opening degree, at this time the guide shaft plays a role as an auxiliary positioning framework; In the lifting and positioning stage, the buckle assembly ensures the stability of the opening degree, and the guide structure maintains the rigidity of the structure; In the occlusion installation stage, the driving force provided by the driving mechanism first overcomes the locking force of the bayonet, so that it is separated; Then the guide shaft and the guide hole guide the precise straight occlusion movement of the movable clamping arm, until the piercing teeth are completely engaged, and the reliable installation is completed. After the installation is completed, the locking force is mainly provided by the mechanical interlocking of the piercing teeth, and the structure is more reliable; At this time, the position of the buckle strip is also close to the buckle hole again, and the protrusion on the inner side of the buckle strip is again deep into the buckle hole, but it no longer bears the main locking function.

[0048] As shown in Figure 6 , as a preferred embodiment, the head 14 of the remote control installation device is made of a metal material that can be magnetically attracted; the top of the output end 221 of the driving mechanism 22 is provided with an elastic clamping tongue 222.

[0049] Specifically, the head is made of a metal material that can be magnetically attracted, cooperates with the first interface provided with a magnetic attraction structure, realizes the quick attraction and separation of the fixed clamping arm and the device head; the top of the output end is provided with an elastic clamping tongue, cooperates with the second interface provided with a clamping groove, and the clamping groove is pressed onto the elastic clamping tongue during installation, and the deformation and rebound of the elastic clamping tongue are used to realize locking; when unlocking, the driving mechanism drives the output end, i.e. the elastic clamping tongue to move downward, forcing the elastic clamping tongue to separate from the clamping groove, so as to realize the separation of the movable clamping arm and the output end.

[0050] As shown in Figures 3 to 7 , the side of the shell 1 is provided with a traction lifting ring 11, and the bottom is provided with an auxiliary lifting ring 12; the auxiliary lifting ring 12 is provided with an auxiliary lifting ring protection cover 121; the top end of the shell 1 is also provided with a guide brim 13, which is inwardly folded to form a limiting structure that partially wraps the fixed clamping arm 41; the lower edge of the guide brim 13 and the fixed clamping arm 41 form a guide gap.

[0051] Specifically, the brim is inwardly folded, partially wrapping the fixed clamping arm from above and side, forming a limiting structure. During the installation process, when the device is pulled upward, the wire first contacts the inclined surface of the brim and slides downward and inward under its guidance, and finally smoothly enters the clamping space formed by the fixed clamping arm and the movable clamping arm through the guide gap, realizing passive precise positioning. When disassembling, the cooperation structure of the brim and the fixed clamping arm requires that the device must move along the predetermined path in the upward direction to separate, effectively preventing accidental unhooking during the recovery process.

[0052] In the use of unmanned aerial vehicle installation remote control installation device, specifically includes the following steps: (1) through the guide structure with fixed clamping arm and movable clamping arm movable connection, and through the temporary locking mechanism to maintain the movable clamping arm in the open position, forming a clamping space for accommodating the wire, complete the pre installation work of the puncture type grounding ring; (2) the fixed clamping arm through the first interface is detachably installed in the head of the installation device, and the second interface of the movable clamping arm is drivingly connected with the output end of the driving mechanism, completing the power docking; (3) one end of the guide rope is fixed on the traction ring of the installation device, and the other end is carried by the unmanned aerial vehicle and leaps over the target wire; the counterweight is dropped on the other side of the line, so that the traction rope is lowered to the ground under the action of gravity. The ground personnel pull the guide rope to vertically lift the installation device to the target installation position near the wire; (4) during the installation device rising, the wire first contacts the guide brim set on the top of the device shell; under the guidance of the inclined surface of the guide brim, the wire is guided downward and inward into the clamping space of the device and positioned; (5) the ground personnel send instructions to the installation device through the remote control module; after receiving the instructions, the control module starts the driving mechanism, and the output end generates thrust to overcome the locking force of the temporary locking mechanism, and drives the movable clamping arm to move along the guide structure to the fixed clamping arm. The occlusion structure is closed, the insulating layer of the wire is pierced and a reliable electrical connection and mechanical locking with the metal wire core are established, and the installation of the puncture type grounding ring is completed; (6) after the installation is completed, the ground personnel controls the driving mechanism again through the remote control module, so that the output end of the driving mechanism is separated from the second interface of the movable clamping arm; then, the installation device head is separated from the first interface of the fixed clamping arm by pulling the guide rope or shaking the rope; finally, the complete installation device is recycled to the ground for next use.

[0053] The unmanned aerial vehicle installation is the best embodiment provided by the application, and the device is suitable for different voltage grades, and can also be operated and installed through the insulating rod.

[0054] The above only describes the preferred embodiment of the application, and is not intended to limit the application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the application shall be included in the protection scope of the application.
