Description

Technical Field

[0001] This utility model relates to the technical field of fuse replacement devices, and in particular to an insulating clamp device for replacing live fuses in drop protection systems. Background Technology

[0002] High-voltage fuses are critical overcurrent protection devices in power systems. Their replacement is extremely risky and must be carried out in strict accordance with safety regulations, usually requiring the power to be disconnected.

[0003] During the replacement of fuses, workers usually climb to a height to connect the two ends of the fuse, so that the fuse can be replaced without interrupting the power supply. However, climbing to a height is inconvenient and also poses certain safety hazards.

[0004] Therefore, it is necessary to provide a device for replacing the insulating clamp of a drop fuse to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an insulating clamp device for replacing live fuses in drop-out protection systems, in order to solve the problem mentioned in the background art that currently, when replacing fuses, workers need to climb to a height to connect the two ends of the fuse so that the fuse can be replaced without interrupting the power supply, but climbing to a height poses certain dangers.

[0006] Based on the above ideas, this utility model provides the following technical solution: a device for replacing the insulating clamp of a drop fuse, comprising: A substrate, on which a clamping assembly is mounted, the clamping assembly having two sets distributed on the same side of the substrate, the clamping assembly including a movable clamp movably connected to the substrate and a fixed clamp fixed to the substrate. The insulating clamp is provided in two sets, and the insulating clamp can be clamped between the fixed clamp and the movable clamp; Metal wire, used to conduct electricity between the two sets of insulating clamps; A drive assembly is mounted on the side of the substrate away from the clamping assembly. The drive assembly is configured to drive two sets of movable clamps on the same side of the substrate to slide relative to the substrate so that the two clamping arms of the insulating clamp move closer to each other.

[0007] As a further embodiment of this utility model: a set of pressure bars is provided on both the front and back sides of the substrate, and the number of pressure bars in each set is set to two and distributed in a cross manner. The two pressure bars located on the front and back sides of the substrate and arranged opposite each other are fixedly connected by a connecting rod, so that the two sets of pressure bars can be opened or folded synchronously.

[0008] As a further embodiment of this utility model: the output end of the drive component is provided with a connecting frame, and the pull rod on the connecting frame is slidably engaged with the pressure rod.

[0009] As a further embodiment of this utility model: guide grooves that cooperate with pull rods are provided on the two pressure rods on one side of the connecting frame. When the pull rod slides in the guide groove, it can drive the two sets of pressure rods to unfold or fold synchronously.

[0010] As a further embodiment of this invention, the two sets of movable clamps are connected by a tension spring.

[0011] As a further embodiment of this invention, a camera is mounted on the substrate.

[0012] As a further embodiment of this utility model: a conductive metal sheet is fixedly embedded in the clamping surface of the clamp, and a metal connecting piece that contacts the metal sheet is fixed on the insulating clamp. The two metal connecting pieces are connected through a metal wire, so that the clamp of the insulating clamp, the metal wire and the fuse can form a current path.

[0013] As a further embodiment of this utility model: the two clamping arms of the insulating clamp are elastically engaged by an elastic element. When the two clamping arms overcome the elastic force and move closer to each other, the clamping head of the insulating clamp is in an open state.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: when the pull rod slides in the guide groove, it can drive the two sets of pressure rods to unfold or fold synchronously. Specifically, as the pressure rod unfolds, the pressure of the pressure rod on the moving clamp causes the two moving clamps on the same side of the substrate to move away from each other to clamp the two clamping arms of the insulating clamp, so that the clamping head of the insulating clamp opens and can clamp at the conductive positions at both ends of the fuse, thereby enabling the fuse to be replaced without interrupting power. Since the clamping assembly and the driving assembly are located on both sides of the substrate, the overall length of the substrate is shortened. Furthermore, driving multiple sets of clamping assemblies with a single driving assembly helps to reduce the overall weight of the device, thus making it easier for workers to lift the substrate with less effort.

[0018] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the actual number, shape, and size of the components in the actual implementation. In the actual implementation, the form, quantity, and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0020] like Figures 1-4 As shown, a drop fuse replacement insulating clamp device includes a base plate 1 and two sets of clamping assemblies mounted on one side of the base plate 1. Each clamping assembly includes a movable clamp 2 and a fixed clamp 3 opposite to the movable clamp 2. Specifically, the fixed clamp 3 is fixedly connected to the base plate 1, and the movable clamp 2 is slidably disposed relative to the base plate 1. In actual use, an insulating clamp 4 is clamped between the movable clamp 2 and the fixed clamp 3. A driving assembly 6 on the side of the base plate 1 away from the clamping assemblies pushes the movable clamp 2 to clamp the insulating clamp 4, causing the insulating clamp 4 to be in an open state. This facilitates clamping the insulating clamp 4 at the conductive position at the end of the fuse. The two sets of insulating clamps 4 are connected by a metal wire 407, enabling the replacement of the fuse without interrupting power.

[0021] The aforementioned driving component 6 can be an electric push rod, and the output end of the electric push rod is fixedly connected to the movable clamp 2, thereby driving the movable clamp 2 to move along the surface of the substrate 1.

[0022] Furthermore, a camera can be installed on the substrate 1, and the camera can be connected to the terminal via 5G signal or Bluetooth, so that the real-time position of the insulating clip 4 relative to the end of the fuse can be displayed by the terminal (such as a mobile phone), which is beneficial for clamping the insulating clip 4 to the end of the fuse.

[0023] Unlike traditional insulating clips 4, in this design, when the two clamping arms 403 of the insulating clip 4 approach each other, the clamping heads 404 on the insulating clip 4 can separate from each other. In this way, when the clamping heads 404 are at both ends of the fuse, pulling the movable clip 2 away from the fixed clip 3 releases the clamping arms 403. At this time, under the elastic force, the clamping heads 404 on the insulating clip 4 can be brought together, thus clamping the two ends of the fuse to make the fuse conductive, which is beneficial for replacing the fuse without interrupting power. In addition, when the movable clip 2 moves away from the fixed clip 3 and disengages from the clamping arms 403, the clamping assembly can also separate from the insulating clip 4, thus eliminating the need to hold the substrate 1 and the clamping assembly for an extended period.

[0024] In summary, when using this device, the moving clamp 2 is pushed by the drive component 6 to open the clamp head 404 of the insulating clamp 4. For easier clamping, one insulating clamp 4 can be clamped to the end of the fuse first. Then, the drive component 6 is reset so that the insulating clamp 4 remains at one end of the fuse. Then, the operator adjusts the position of the other insulating clamp 4 to align it with the other end of the fuse. The drive component 6 is then used again to open and clamp the insulating clamp 4 to the other end of the fuse. At this point, both ends of the fuse are in a conductive state.

[0025] A set of pressure rods 7 is provided on both the front and back sides of the substrate 1. The number of pressure rods 7 in each set is set to two and they are distributed in a cross manner. The two pressure rods 7 located on the front and back sides of the substrate 1 and arranged opposite each other are fixedly connected by a connecting rod 9, so that the two sets of pressure rods 7 can be opened or folded synchronously. A pin 11 is rotatably connected to the base plate 1 via a bearing. The pin 11 passes through the center of multiple sets of pressure rods 7 and is rotatably connected to the pressure rods 7 via the bearing. Figures 1-2 As shown, the substrate 1 has a plurality of arc-shaped grooves 10 that cooperate with the connecting rod 9. The center of the arc-shaped groove 10 coincides with the axis of the pin 11, so that the connecting rod 9 can slide in the arc-shaped groove 10. In this embodiment, the drive assembly 6 includes an electric push rod and a connecting frame 8 fixed to the output end of the electric push rod. A pull rod 801 is fixedly mounted on the connecting frame 8. Figure 2As can be seen, both pressure rods 7 on one side of the connecting frame 8 are provided with guide grooves 701 that cooperate with the pull rod 801. When the pull rod 801 slides in the guide grooves 701, it can drive the two sets of pressure rods 7 to unfold or fold synchronously. Specifically, as the pressure rods 7 unfold, the pressure of the pressure rods 7 on the movable clamps 2 causes the two movable clamps 2 on the same side of the substrate 1 to move away from each other to clamp the two clamping arms 403 of the insulating clamp 4, so that the clamping head 404 of the insulating clamp 4 opens and can be clamped at the conductive positions at both ends of the fuse. In this solution, since the driving component 6 and the clamping component are respectively arranged on both sides of the substrate 1, the overall length of the substrate 1 is shortened, which makes it easier for the operator to lift the substrate 1 with less effort.

[0026] Reference Figure 1 As shown, a sleeve is fixedly provided on the substrate 1, and a support rod 5 is detachably connected to the sleeve by bolts or screws, so as to lift the substrate 1 to a high place by means of the support rod 5.

[0027] Combination Figure 1-4 As shown, a groove 101 is formed on the surface of the substrate 1, and a slider 201 is fixedly provided on the movable clamp 2, so that the slider 201 is slidably assembled in the groove 101. The cross-sections of the slider 201 and the groove 101 are both T-shaped structures, thereby preventing the movable clamp 2 from detaching from the substrate 1.

[0028] A tension spring 12 connects the two movable clamps 2. When the pressure rod 7 is folded, the tension force of the tension spring 12 on the movable clamps 2 can cause the two movable clamps 2 to gradually move away from the fixed clamp 3 and return to their original position.

[0029] The two insulating clips 4 are connected by a metal wire 407. When the two insulating clips 4 are clamped at the conductive ends of the fuse, the two ends of the fuse can be connected through the insulating clips 4 and the metal wire 407 on the insulating clips 4, so that the fuse can be replaced without interrupting the power supply. Specifically, a conductive metal piece 408 is fixedly embedded in the clamping surface of the clip 404, and a metal connecting piece 402 in contact with the metal piece 408 is fixed on the insulating clip 4. The two ends of the metal wire 407 are respectively connected to the metal connecting pieces 402 on the two insulating clips 4, so that the clips 404, the metal wire 407 and the fuse can form a current path.

[0030] Combination Figure 3As shown, two sets of circular protrusions 406 are provided at the junction of the clamping arm 403 and the clamp 404. It should be noted that the outer set of protrusions 406 is fixedly connected to one of the clamping arms 403, while the inner set of protrusions 406 is fixedly connected to the other clamping arm 403. A pivot pin 405 is provided at the center of each protrusion 406. The pivot pin 405 passes through both sets of protrusions 406 and is rotatably connected to them. The cross-section of the pivot pin 405 along its own axis is I-shaped, thus preventing the pivot pin 405 from detaching from the protrusions 406. The clamping arms 403 of the insulating clamp 4 are elastically connected by an elastic element 401. The elastic element 401 can be a spring or a torsion spring, etc. Specifically, when the elastic element 401 is a spring, it can be installed between the two clamping arms 403. When the elastic element 401 is a torsion spring, it can be sleeved on the outside of the shaft pin 405 and the two ends of the torsion spring abut against the inside of the clamping arms 403. In this way, when the driving component 6 drives the moving clamp 2 away from the fixed clamp 3, the insulating clamp 4 can clamp the end of the fuse, so that it is not necessary to hold the substrate 1 and the clamping component for a long time.

[0031] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
