Description

Technical Field

[0001] The invention relates to the technical field of low-voltage live working, and in particular to an insulating wire clamp used for low-voltage live working. Background Art

[0002] Daily low-voltage live operations in the power industry, such as replacing meters and switches under power, require the power cord to be disconnected phase by phase and the exposed joints to be temporarily insulated in order to avoid electric shock, grounding, and phase-to-phase short circuits. After replacing the equipment, the insulation must be removed phase by phase and the equipment must be connected.

[0003] Building an intrinsically safe enterprise has become the mission given to power grid companies in the new era, but accidents in low-voltage live operations often occur. The main risks of low-voltage live operations are electric shock, single-phase grounding, and phase-to-phase short circuits. Traditional low-voltage live operations, for example, the main link of replacing a three-phase four-wire meter, requires wrapping the insulation of four wires and then removing the insulation of the four wires. This results in a large workload and low work efficiency. In addition, repetitive work can easily cause construction workers to have a reduced safety awareness, resulting in accidents such as electric shock.

[0004] In the prior art, the main method for temporary insulation wrapping is to use insulating tape wrapping, but there are the following disadvantages:

[0005] 1. The insulation tape is not wrapped properly, the number of wrapping layers is small, the wire cut is sharp and will pierce the insulation tape, etc., resulting in the insulation effect not meeting the requirements;

[0006] 2. There are many wires that need to be insulated. Three-phase four-wire operation requires wrapping the insulation of four wires. Removing the insulation of four wires takes a lot of time and has low work efficiency.

[0007] 3. If you tear off the tape by hand, there is a risk of accidentally touching the equipment and causing personal injury. If you work at high altitude, it is easy to cause the body's center of gravity to be unstable, and there is a risk of falling from a high altitude;

[0008] 4. Due to the stickiness of insulating tape, especially some insulating tape exposed to high temperature, it is difficult to find the opening when using and removing the insulating tape, which causes great inconvenience when working with insulating gloves or canvas gloves. There is a risk of electric shock caused by loosening the gloves;

[0009] 5. The work of wrapping insulating tape involves repeated wrapping, which can easily cause fatigue among construction workers and reduce their safety awareness, leading to accidents such as electric shock, grounding, and phase short circuit. Summary of the invention

[0015] Furthermore, an anti-slip pad layer is provided on the inner side of each clamping body facing the clamping channel.

[0016] Furthermore, the anti-skid pad layer is made of high-density sponge or rubber material.

[0017] Furthermore, the wire clamp component also includes a pivot shaft, which is used to pivotally connect the two clamping members. The elastic member is a torsion spring, which is located at the outer periphery of the pivot shaft, and the two torsion arms of the torsion spring are respectively in contact with the two clamping members.

[0018] Furthermore, one of the two clamping members also includes two first mounting members connected to the wire clamp handle, and the two first mounting members are arranged at intervals along the extension direction of the clamping channel; the other of the two clamping members also includes two second mounting members connected to the wire clamp handle, and the two second mounting members are arranged at intervals along the extension direction of the clamping channel; the two second mounting members are located between the two first mounting members, the pivot shaft passes through the two first mounting members and the two second mounting members, and the torsion spring is located between the two second mounting members.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] like Figures 1 to 7 As shown, an embodiment of the present invention provides an insulating wire clamp for low-voltage live working, the insulating wire clamp for low-voltage live working includes a wire clamp component 15, the wire clamp component 15 includes: two clamping members, each clamping member includes a clamping body 2 and a wire clamp handle 10 connected to the clamping body 2, the two clamping bodies 2 have a clamping position close to each other to enclose a clamping channel, and a release position away from each other and releasing the wire harness; an elastic member 6, used to provide a clamping force to the two clamping members to maintain the clamping position, and the surface of each clamping member and the surface of the elastic member 6 are provided with an insulating layer.

[0035] In the above technical scheme, the operator holds the wire clamp handle 10, opens the two clamping bodies 2 of the wire clamp component 15 to the release position, puts the exposed wire harness into the clamping channel, ensures that the wire harness is completely located in the channel between the clamping bodies 2, and avoids the sharp part of the wire harness cut being exposed. By releasing the wire clamp handle 10, the two clamping bodies 2 are brought close to each other to the clamping position. At this time, the elastic member 6 applies appropriate clamping force to ensure that the wire harness is stably clamped and will not be damaged. After the operation is completed, the two clamping bodies 2 are returned to the release position by opening the wire clamp handle 10 to release the clamping of the wire harness. Through the above use process, the insulating wire clamp of the present invention can effectively perform temporary insulation wrapping on the exposed wire harness in low-voltage live operation. In this way, on the one hand, the use of the insulating wire clamp instead of the traditional insulating tape wrapping can avoid the risk of damage caused by the wrapping. It can effectively reduce the occurrence of accidents, especially when working at height or with a large workload, by eliminating safety hazards such as electric shock, grounding or phase-to-phase short circuit caused by insufficient or careless operation; on the other hand, the insulating wire clamp adopts a "clip" type operation method, which is easy and quick to operate, and does not require a lot of time to wrap and remove the insulating tape, significantly shortening the construction time of low-voltage live operations and improving work efficiency; on the other hand, there is no need to use insulating tape for insulating wrapping, which can not only avoid the problems of missing wrapping and few wrapping layers, thereby avoiding the problem that the sharp cut of the wire will pierce the insulating tape and cause the insulation effect to not meet the requirements, but also avoid the problem of accidentally touching the equipment and causing personal injury due to tearing the tape off by hand, and avoid the risk of electric shock due to difficulty in finding an opening when removing the insulating tape.

[0036] In one embodiment, each clamping member may be made of insulating material, meeting the requirements of insulation strength and rigidity, and being drop-resistant and scratch-resistant.

[0037] It should be noted that if Figure 1 As shown, in the embodiment of the present invention, the cross section of the clamping channel is circular.

[0038] It should be noted that if Figure 1 As shown, in the embodiment of the present invention, because the insulating wire clamp needs to adapt to cables of various specifications, the wire clamp handle 10 is provided with an arc surface, so that the handle with an arc can facilitate opening the wire clamp.

[0039] like Figure 1 As shown, in an embodiment of the present invention, the insulating wire clamp used for low-voltage live working also includes a wire clamp top stop 3. Along the extension direction of the clamping channel, the wire clamp top stop 3 is located on one side of the clamping channel, and the wire clamp top stop 3 is connected to the top end of one of the two clamping bodies 2.

[0040] In the above technical scheme, the wire clamp top stop 3 is arranged on one side of the clamping channel, which can effectively prevent the wire harness from exceeding the range of the clamping body 2 during the clamping process, ensure that the exposed part of the wire harness is completely covered by the clamping body 2, and avoid safety problems such as electric shock, short circuit or grounding caused by the exposed wire harness; and the connection between the wire clamp top stop 3 and the top of the clamping body 2 provides a positioning and limiting function for the wire harness, which helps to accurately place the wire harness in the clamping channel, reduces the unstable clamping phenomenon caused by improper position of the wire harness, and improves the reliability of the insulation effect; and the setting of the wire clamp top stop 3 not only limits the range of movement of the wire harness, but also protects the fingers of the operator, avoiding accidental pinching of the fingers during the clamping of the wire harness, and increasing the safety factor during the operation.

[0041] like Figures 1 to 3 As shown, in an embodiment of the present invention, an insulating wire clamp for low-voltage live working includes a plurality of wire clamp components 15 connected in sequence, a first wire clamp component 15 among the plurality of wire clamp components 15 is provided with a wire clamp top stop 3 at one end, and the other end of the first wire clamp component 15 among the plurality of wire clamp components 15 is connected to a second wire clamp component 15 among the plurality of wire clamp components 15.

[0042] In the above technical scheme, on the one hand, multiple wire clamp components 15 can be connected in sequence to form an insulating wire clamp combination of any length, which makes the insulating wire clamp suitable for exposed wire harnesses of different lengths. Whether it is short-distance wire harness insulation or long-distance insulation processing, it can be properly solved, which significantly improves the applicability and flexibility; on the other hand, by connecting multiple wire clamp components 15 into a continuous system, the stability of the entire insulating wire clamp is increased, especially when processing long wire harnesses, it can effectively prevent the wire harness from sliding in the clamping channel, ensuring the continued effectiveness of the insulation effect; on the other hand, one end of the first wire clamp component 15 is provided with a wire clamp top stop 3, which can be used as the starting point positioning of the wire harness to prevent the wire harness from exceeding the range of the clamping channel during the clamping process; on the other hand, the continuous use of multiple wire clamp components 15 avoids the trouble of frequently replacing or splicing insulating tools when processing long wire harnesses, optimizes the operation process, greatly improves the operation efficiency, and reduces the operation time.

[0043] like Figure 1 and Figure 5 As shown, in the embodiment of the present invention, one of the two adjacent wire clamp members 15 is provided with a buckle 8, and the other of the two adjacent wire clamp members 15 is provided with a clamping groove 9, and the clamping groove 9 is engaged with the buckle 8. In this way, the connection between the two adjacent wire clamp members 15 can be achieved, and the above connection method can achieve quick disassembly and connection to improve work efficiency.

[0044] Specifically, in an embodiment of the present invention, a buckle 8 is provided at one end of the first wire clamp component 15, a wire clamp top stop 3 is provided at the other end of the first wire clamp component 15, and each wire clamp component 15 in the remaining wire clamp components 15 (except the wire clamp components 15 other than the first wire clamp component 15) is provided with a groove 9 at one end and a buckle 8 at the other end to achieve connection between two adjacent wire clamp components 15.

[0045] like Figure 1 As shown, in the embodiment of the present invention, an anti-slip pad layer 7 is provided on the inner side of each clamping body 2 facing the clamping channel.

[0046] In the above technical solution, the provision of the anti-skid pad layer can increase the friction between the insulating wire clamp and the wire harness, and can maintain a stable clamping of the wire harness even in a humid or oily environment, and is suitable for various harsh working environments, such as rainy days, industrial areas, etc. In humid and oily environments such as rainy days or industrial areas, the addition of the anti-skid pad layer significantly improves the clamping effect of the wire clamp, avoids safety accidents caused by sliding of the wire harness, and ensures the smooth progress of the operation.

[0047] Preferably, in the embodiment of the present invention, the anti-slip pad layer 7 is made of high-density sponge or rubber material.

[0048] Through the above settings, the high-density sponge or rubber material not only has good anti-slip performance, but also has a certain elasticity, which can adapt to wire harnesses of different diameters, and at the same time plays a certain protective role on the wire harness during the clamping process to prevent the wire harness from being damaged during the clamping process, and is suitable for clamping operations of various wire harnesses, such as power lines, communication lines, cables, etc. The selection of high-density sponge or rubber material not only improves the service life of the anti-slip pad, but also can effectively absorb the impact during the clamping process to avoid damage to the wire harness, especially when handling fragile communication lines and cables.

[0049] like Figure 4 and Figure 6 As shown, in the embodiment of the present invention, the wire clamp component 15 also includes a pivot shaft 5, which is used to pivotally connect the two clamping members. The elastic member 6 is a torsion spring, which is located on the outer periphery of the pivot shaft 5. The two torsion arms of the torsion spring are respectively in contact with the two wire clamp handles 10.

[0050] In the above technical solution, the two clamping members rotate freely around the pivot shaft 5. By pressing the two wire clamp handles 10, the elastic force of the torsion spring can be overcome so that the two clamping bodies 2 can be opened to clamp the wire harness. The elastic force of the torsion spring ensures that the clamping members remain in a closed state when there is no external force, forming a stable clamping force, which is convenient for the operator to quickly clamp the wire harness. The torsion spring can provide a continuous and stable clamping force. Even if an unexpected external force shock or vibration is encountered during live operation, the wire harness can be stably clamped, avoiding the loosening of the wire clamp due to insufficient clamping force, thereby reducing the risk during the operation.

[0051] Specifically, in the embodiment of the present invention, the exterior of the torsion spring is covered with plastic insulation or rubber material.

[0052] like Figure 4 and Figure 6 As shown, in the embodiment of the present invention, one of the two clamping members further includes two first mounting members 13 connected to the wire clamp handle 10, and the two first mounting members 13 are arranged at intervals along the extension direction of the clamping channel; the other of the two clamping members further includes two second mounting members 14 connected to the wire clamp handle 10, and the two second mounting members 14 are arranged at intervals along the extension direction of the clamping channel; the two second mounting members 14 are located between the two first mounting members 13, the pivot shaft 5 passes through the two first mounting members 13 and the two second mounting members 14, and the torsion spring is located between the two second mounting members 14. In this way, the first mounting member 13 and the second mounting member 14 can provide stable support for the pivot shaft 5, which can not only realize the pivot connection between the two clamping members, but also ensure that the two clamping members can be accurately aligned and stably clamped when clamping the wire harness, reducing the problem of uneven clamping force caused by loose or misaligned components.

[0053] like Figure 4 As shown, in the embodiment of the present invention, the clamping body 2 includes a connecting body 21 and a plurality of clamping arms 22 connected to the connecting body 21 , the plurality of clamping arms 22 are arranged at intervals along the extension direction of the clamping channel, and the connecting body 21 is connected to the wire clamp handle 10 .

[0054] Through the above-mentioned arrangement, a plurality of clamping arms 22 are arranged at intervals along the extension direction of the clamping channel, which can increase the contact area with the wire harness, and can more evenly distribute the clamping force, thereby avoiding deformation or damage of the wire harness due to the concentrated force of a single clamping point, and at the same time improving the clamping stability of the wire harness; and through the arrangement of a plurality of clamping arms 22, the wire clamp can adapt to wire harnesses of different shapes and diameters, and can ensure that the wire harness is firmly clamped even when processing wire harnesses with irregular shapes or thicker wire diameters, thereby improving the scope of application and flexibility.

[0055] In the prior art, in order to identify the phase sequence, the general method is to use different colors of insulating tape or use a pen to mark it, which will increase the complexity of the work and cause the phase sequence to be wrong if you are not careful. Figure 3 As shown, in the embodiment of the present invention, any one of the two wire clamp handles 10 is provided with a paddle slot 11, and the wire clamp component 15 also includes a phase identification component 1, which is installed in the paddle slot 11, and the phase identification component 1 can indicate any one of the phase identification parts A, B, C and N.

[0056] In the above technical solution, by setting the phase identification component 1, the operator can intuitively identify the phase (A, B, C or N) corresponding to the wire clamp. For operations on multi-phase lines, it can effectively avoid phase sequence confusion, reduce electrical accidents caused by phase errors, and ensure the safety of power grid operations; through the accurate selection of the phase identification part, it can ensure that each clamping operation is targeted at the correct phase cable. For operation scenarios that require precise phase isolation, such as live replacement of metering equipment or switches, the accuracy of the operation can be significantly improved.

[0057] Furthermore, traditional phase identification methods, such as using different colored insulating tapes or handwritten marks, can easily cause visual confusion during long-term operations, especially in low light or poor visibility. The phase identification component design of the present invention can clearly display phase information even under adverse conditions, avoiding the safety hazards caused by visual confusion; and the phase identification component 1 is replaceable. When the mark is worn, it can be easily removed from the paddle slot 11 and replaced with a new phase identification component, reducing the maintenance cost and time of the tool and improving the continuity of the operation; in the teamwork operation scene, the clear identification of the phase identification component 1 helps to effectively communicate between different operators, ensuring that everyone can accurately understand the phase information of the cable, avoiding operation delays or safety issues caused by information transmission errors.

[0058] Specifically, Figure 8As shown, in the embodiment of the present invention, the phase identification component 1 includes a mounting body installed in the paddle slot 11, and the mounting body is provided with four phase identification parts A, B, C and N, each identification part has a clear distinguishing mark, which can be a color, a symbol or a text, for example, the four letters A, B, C and N, and the mounting body is also provided with four slide grooves 24, and the four slide grooves 24 are arranged one by one corresponding to the four phase identification parts A, B, C and N, and each slide groove 24 is provided with a paddle 25, and the paddle 25 can move in the slide groove 24 to approach or move away from the corresponding phase identification part, wherein the paddle 25 is close to the corresponding phase identification part, indicating that the insulating wire clamp clamps the wire harness of the phase. Among them, the phase identification component 1 is made of insulating material to ensure that the entire component has good insulation performance and prevent safety accidents during live operation. The above operation is simple. The phases of the wires are determined according to the usage requirements. According to the required phases, the paddle 25 with the corresponding serial number is turned to distinguish the phase sequence of the wires. The correct phase identification part can be selected by gently turning it. No additional tools or complicated setting process are required, which greatly improves the efficiency and convenience of on-site operations.

[0059] Furthermore, on-site construction operations involve the simultaneous construction of multi-phase cables. For better identification and distinction, a paddle 25 with ABCN numbers is designed, and corresponding numbered wire clamps are used to clamp the corresponding phase-to-phase wires. Whether the same person or multiple people are working together, the phase-to-phase cables can be clearly identified to prevent errors in the later access equipment or power grid, thereby avoiding major power safety accidents.

[0060] In some embodiments, a simple locking mechanism, such as a spring catch or magnetic adsorption, may be provided between the slide slot 24 and the paddle 25 to ensure that the selected phase identification portion remains fixed during the entire operation.

[0061] It should be noted that, in the embodiment of the present invention, the A, B, C, and N phase identification parts are specific display parts of the phase identification component 1, which are used to distinguish different phases.

[0062] It should be noted that in the embodiment of the present invention, a single insulating wire clip is about 30 mm long and weighs about 30 g, which is easy to carry and has wide applicability. It is suitable for wires of all wire diameters and is provided with an anti-slip pad layer, which is suitable for wires of 1.5-240 mm in diameter. 2 of wire.

[0063] It should be noted that, in the embodiments of the present invention, the method of using the "clip" is to "clamp" the exposed joint in the middle, and the clamping force is appropriate and not easy to loosen; it is suitable for wires of all diameters; buckles 8 and slots 9 are provided at both ends of the insulating wire clamp, and multiple wire clamp components 15 can be connected together, and the length can be infinitely extended. The insulating wire clamp can be reused, saving insulating tape and improving economy. The insulating wire clamp can increase the work efficiency of maintenance personnel, simplify the work process, and ensure the safety of maintenance personnel during the construction process. It is widely suitable for low-voltage live operations and provides a practical solution for temporary insulation wrapping of exposed wires (joints).

[0064] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the operator holds the wire clamp handle, opens the two clamping bodies of the wire clamp component to the release position, puts the exposed wire harness into the clamping channel, ensures that the wire harness is completely located in the channel between the clamping bodies, and avoids the sharp part of the wire harness cut being exposed, and releases the wire clamp handle to make the two clamping bodies approach each other to the clamping position. At this time, the elastic member applies appropriate clamping force to ensure that the wire harness is stably clamped and will not be damaged. After the operation is completed, the wire clamp handle is opened to return the two clamping bodies to the release position to release the clamping of the wire harness. Through the above-mentioned use process, the insulating wire clamp of the present invention can effectively perform temporary insulation wrapping on the exposed wire harness in low-voltage live operation. In this way, on the one hand, the insulating wire clamp is used instead of the traditional insulating tape wrapping. It can avoid safety hazards such as electric shock, grounding or phase-to-phase short circuit caused by insufficient wrapping or careless operation, especially when working at high altitude or with a large workload, and can effectively reduce the occurrence of accidents; on the other hand, the insulating wire clamp adopts a "clip" type operation method, which is simple and quick to operate, and does not require a lot of time to wrap and remove the insulating tape, which significantly shortens the construction time of low-voltage live operations and improves work efficiency; on the other hand, there is no need to use insulating tape for insulating wrapping, which can not only avoid the problems of missing wrapping and few wrapping layers, thereby avoiding the problem that the sharp cut of the wire will pierce the insulating tape and cause the insulation effect to not meet the requirements, but also avoid the problem of accidentally touching the equipment and causing personal injury due to tearing the tape off by hand, and avoid the risk of electric shock due to difficulty in finding an opening when removing the insulating tape.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
