Description

Technical Field

[0001] This application relates to the field of intelligent monitoring technology, and in particular to an electric clamping device. Background Technology

[0002] In existing power distribution networks, drop-out fuses are installed on transmission lines. When the current in the transmission line is too high, the fuse will drop its fuse tube, cutting off the transmission line and protecting it. However, drop-out fuses do not have current detection capabilities, so a detection device needs to be installed on them. If the detection device malfunctions, it also needs to be removed from the drop-out fuse for inspection and repair.

[0003] In the existing technology, drop-out fuses are generally installed at a height of 5 to 14 meters in the air. There are a large number of drop-out fuses, which are distributed in different locations. Operators need to climb to a high place to install a detection device on each drop-out fuse. When the detection device is repaired, the operator needs to climb to a high place to remove the detection device from each drop-out fuse.

[0004] However, the above-mentioned methods for installing and disassembling the testing device pose safety hazards and are not efficient due to the inability to do so quickly. Furthermore, installing and disassembling the testing device using these methods requires disconnecting the power distribution network, affecting the normal operation of the transmission lines within the network. Therefore, how to safely and quickly install and disassemble the testing device without interrupting power supply has become a pressing technical problem that needs to be solved. Utility Model Content

[0005] The purpose of this application is to provide an electric clamping device that enables safe and rapid installation and removal of a detection device without interrupting power.

[0006] The embodiments of this application are implemented as follows:

[0007] This application provides an electric clamping device for installing a detection device for a drop-out fuse. The detection device includes a first component and a second component, one end of which is connected by an elastic element to movably clamp the drop-out fuse. The electric clamping device includes a handheld end, an insulating rod, and a clamping end connected in sequence. The clamping end has a receiving groove for accommodating the detection device, a first communication module, a drive module, and a clamping module connected to the drive module. The clamping module has a clamping state that drives the first component and the second component to move simultaneously to clamp the detection device onto the drop-out fuse. The clamping module also has a releasing state that drives the detection device to release the drop-out fuse. When the detection device is located in the receiving groove, if the drive module receives a clamping signal sent by the first communication module, the drive clamping module switches from the releasing state to the clamping state. When the drive module receives a release signal sent by the first communication module, the drive clamping module switches from the clamping state to the releasing state.

[0008] In one embodiment, the clamping module includes a clamping plate and a pressure plate. In the clamping state, the clamping plate fixes the first component and the pressure plate presses one end of the second component. In the releasing state, the clamping plate separates from the first component and the pressure plate separates from the second component.

[0009] In one embodiment, the pressure plate includes a connecting portion and a body portion connected to the connecting portion. The connecting portion is sleeved on the rotation output shaft of the drive module. When the drive module receives a clamping signal, it drives the body portion to rotate from a first position to a second position. When the drive module receives a release signal, it drives the body portion to rotate from the second position to the first position.

[0010] In one embodiment, the clamping plate is connected to the rotary output shaft of the drive module via a transmission assembly. The first assembly has a first mating part, and the pressure plate has a second mating part. When the drive module receives a clamping signal, it is linked with the transmission assembly to move the second mating part linearly from a third position where it is separated from the first mating part to a fourth position where it is mated with the first mating part. When the drive module receives a release signal, it is linked with the transmission assembly to drive the second mating part to move linearly from the fourth position to the third position.

[0011] In one embodiment, the transmission assembly includes a rotating shaft and a transmission component; one end of the rotating shaft is sleeved on a rotating output shaft, and the other end of the rotating shaft is provided with an eccentric rotating shaft; one end of the transmission component is connected to the eccentric rotating shaft, and the other end of the transmission component is connected to a clamping plate.

[0012] In one embodiment, the clamping end is provided with a limiting element for limiting the movement of the transmission component.

[0013] In one embodiment, the clamping end has a detection element for detecting whether the detection device is located in the receiving groove, and the handheld end has a display element for displaying the detection result of the detection device.

[0014] In one embodiment, the handheld terminal has a detachable control module, which is provided with a second communication module, a clamping button and a release button; when the clamping button is triggered, the second communication module sends a clamping signal to the first communication module; when the release button is triggered, the second communication module sends a release signal to the first communication module.

[0015] In one embodiment, the drive module and clamping plate are located on both sides of the receiving groove, and the transmission component is located above the receiving groove.

[0016] In one embodiment, the surface of the clamping plate is covered with a first anti-slip layer, and the surface of the pressure plate includes a second anti-slip layer.

[0017] In this application, operators can install and disassemble the testing device from the ground without climbing to a height, by manipulating the electric clamping device. This method offers enhanced safety and higher efficiency. Furthermore, the electric clamping device can be used to install and disassemble drop-out fuses even when the power transmission lines in the distribution network are not powered off, without affecting the normal operation of the transmission lines. In summary, the electric clamping device in this application enables safe and rapid installation and disassembly of the testing device without power interruption.

[0018] Alternatively, a mechanical control mechanism can be installed on the handheld end, allowing the operator to manually control and switch the state of the control structure to enable the clamping end to perform clamping and releasing actions. However, the above method requires manual operation of the control mechanism, resulting in a low level of automation and increasing hand fatigue. Furthermore, this method also requires a mechanical control structure on the handheld end, increasing the weight of the clamping device. This application solves these problems by using an electrically controlled drive method that sends clamping and releasing signals to the clamping end to perform clamping and releasing actions.

Detailed Implementation

[0033] The terms “first,” “second,” “third,” etc., are used only for distinguishing descriptions and do not indicate a sequence number, nor should they be interpreted as indicating or implying relative importance.

[0034] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0035] In the description of this application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0037] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0038] This application provides an electric clamping device 10 for installing a detection device 20 for a drop-out fuse 30, such as... Figure 1 As shown, the detection device 20 includes a first component 210 and a second component 220, with one end of the first component 210 and the second component 220 connected by an elastic element such as a torsion spring. Figure 2 As shown, the electric clamping device 10 includes a handheld end 110, an insulating rod 120, and a clamping end 100 connected in sequence. The clamping end 100 has a receiving groove 1041 for accommodating the detection device 20, a first communication module, a drive module, and a clamping module connected to the drive module. The clamping module has a clamping state that drives the first component 210 and the second component 220 to move simultaneously to clamp the detection device 20 onto the drop-out fuse 30. The clamping module also has a releasing state that drives the detection device 20 to release the drop-out fuse 30.

[0039] When installing the detection device 20, the operator can place the electric clamping device 10 on a horizontal surface and place the detection device 20 into the receiving groove 1041. After placement, a clamping signal is sent to the first communication module. Upon receiving the clamping signal, the first communication module forwards the clamping signal to the drive module. After receiving the clamping signal, the drive module drives the clamping module to switch from the released state to the clamping state to clamp the detection device 20. Figure 3 As shown, after the detection device 20 is clamped, the other ends of the first component 210 and the second component 220 form a preset angle. At this time, the operator can hold the handheld end 110 to move the electric clamping device 10 to the drop-out fuse 30. After successful movement, the position of the electric clamping device 10 is adjusted so that the angle formed by the first component 210 and the second component 220 is aligned with the fuse tube 31 of the drop-out fuse 30. After successful alignment, the operator sends a release signal to the first communication module. After receiving the release signal, the first communication module forwards the release signal to the drive module. After receiving the release signal, the drive module drives the clamping module to switch from the clamping state to the release state to release the detection device 20. After the detection device 20 is released, the first component 210 and the second component 220 clamp the fuse tube 31 under the action of the elastic element. In this way, the installation operation of the detection device 20 is completed.

[0040] When disassembling the detection device 20, such as Figure 4 As shown, the operator can hold the handheld end 110 and, after successful gripping, move the electric clamping device 10 to the drop-out fuse 30. After successful movement, adjust the position of the electric clamping device 10 so that the detection device 20 enters the receiving slot. Upon successful entry, a clamping signal is sent to the first communication module. The first communication module, upon receiving the clamping signal, forwards it to the drive module. Upon receiving the clamping signal, the drive module drives the clamping module to switch from the release state to the clamping state to clamp the detection device 20. After the detection device 20 is clamped, the other ends of the first component 210 and the second component 220 form the maximum angle of divergence. At this point, the operator can place the electric clamping device 10 on a horizontal surface. After successful placement, a release signal is sent to the first communication module. Upon receiving the release signal, the first communication module forwards it to the drive module. Upon receiving the release signal, the drive module drives the clamping module to switch from the clamping state to the release state to release the detection device 20. This completes the disassembly operation of the detection device 20.

[0041] As can be seen from the above, in this application, operators can install and disassemble the detection device 20 from the ground without climbing to a height, by manipulating the electric clamping device 10. This method offers enhanced safety and higher efficiency. Furthermore, the electric clamping device 10 can also install and disassemble the drop-out fuse 30 even when the power transmission line in the distribution network is not interrupted, without affecting the normal operation of the power transmission line. In summary, the electric clamping device 10 in this application enables safe and rapid installation and disassembly of the detection device 20 without interrupting power.

[0042] Alternatively, a mechanical control mechanism can be installed on the handheld end 110, allowing the operator to manually control and switch the state of the control structure to enable the clamping end 100 to perform clamping and releasing actions. However, the above method requires manual operation of the control mechanism, resulting in low automation and increased hand fatigue. Furthermore, this method also requires a mechanical control structure on the handheld end 110, increasing the weight of the clamping device. This application utilizes an electrically controlled drive method that sends clamping and releasing signals to the clamping end 100 to perform clamping and releasing actions, effectively solving the aforementioned problems.

[0043] In some preferred embodiments, such as Figure 7 As shown, the handheld terminal 110 has a detachable control module 112, which is equipped with a second communication module, a clamping button and a release button.

[0044] When the control module 112 is installed on the handheld terminal 110, the operator can trigger the clamping button to send a clamping signal from the second communication module to the first communication module; the operator can trigger the release button to send a release signal from the second communication module to the first communication module.

[0045] Because the drop-out fuse 30 is installed at a high altitude and may be obstructed, operators may sometimes be unable to simultaneously move the electric clamping device 10 and observe the positional relationship between the electric clamping device 10 and the detection device 20 to trigger the button. In this case, the control module 112 can be detached from the handheld end 110 and given to an observer. The operator can then move the electric clamping device 10, allowing the observer to observe the positional relationship between the electric clamping device 10 and the detection device 20, and trigger the button based on the observation. This separates the moving electric clamping device 10 from the electronic control device, improving the loading and unloading efficiency of the detection device 20.

[0046] As can be seen, in the above embodiment, the control module 112 is detachably mounted on the handheld end 110, which enables the electric clamping device 10 to be operated in different ways according to different scenarios. It is highly flexible and can meet the needs of various scenarios.

[0047] In some preferred embodiments, the clamping signal and the release signal can be Bluetooth, 4G or 5G signals.

[0048] In some preferred embodiments, the clamping module needs to be in a released state before the detection device 20 is installed and removed. If the initial state of the clamping module is the released state, no operation is required; if the initial state of the clamping module is the clamped state, the clamping module needs to be switched to the released state.

[0049] In some preferred embodiments, such as Figure 2 As shown, the clamping module includes a clamping plate 103 and a pressure plate 107. In the clamping state, the clamping plate 103 fixes the first component 210, and the pressure plate 107 presses one end of the second component 220; in the releasing state, the clamping plate 103 separates from the first component 210, and the pressure plate 107 separates from the second component 220.

[0050] In this embodiment, when the detection device 20 is clamped, the clamping plate 103 is responsible for fixing the detection device 20, and the pressure plate 107 is responsible for pressing the detection device 20, which effectively alleviates the movement of the detection device 20 and improves the clamping efficiency and clamping effect of the detection device 20.

[0051] In some preferred embodiments, such as Figure 1 , Figure 2 and such Figure 11 As shown, the pressure plate 107 includes a connecting part 1071 and a body part 1072 connected to the connecting part 1071. The connecting part 1071 is sleeved on the rotating output shaft of the drive module. The clamping plate 103 is connected to the rotating output shaft of the drive module through the transmission assembly 300. The first assembly 210 is provided with a first mating part 1031, and the pressure plate 107 includes a second mating part 211.

[0052] When a clamping signal is received, the rotation output axis of the drive module rotates in the first direction, driving the main body 1072 to rotate. Figure 5 The first position, which is separated from the second component 220, is rotated to Figure 6 The second position where the second component 220 is pressed is reached; simultaneously, when the drive module rotates in the first direction, it is linked with the transmission component 300, causing the second mating part 211 to move from the second position where the second component 220 is pressed; Figure 5 The third position, where the first mating part 1031 is separated, moves linearly to... Figure 6 The fourth position is where the second component 220 is fixed in place by cooperating with the first mating part 1031. After both the clamping plate 103 and the pressure plate 107 have moved, the detection device 20 is clamped.

[0053] Upon receiving the release signal, the rotation output axis of the drive module rotates in the second direction, causing the main body 1072 to move from... Figure 6 The second position where the second component 220 is pressed is rotated to Figure 5 The first position where it separates from the second component 220; simultaneously, when the drive module rotates in the second direction, it is linked with the transmission component 300, causing the second mating part 211 to move from... Figure 6 The fourth position of the mating part 1031 moves linearly to the position where it mates with the first mating part 1031. Figure 5 The third position is where the device 20 is separated from the first mating part 1031. After both the clamping plate 103 and the pressure plate 107 have moved, the detection device 20 is released.

[0054] In the above embodiments, there is no need to set up multiple drive modules. The movement of the clamping plate 103 and the pressure plate 107 can be controlled simultaneously by only one drive module. The compact structure meets the design requirements of miniaturization and enhances the product competitiveness.

[0055] As can be seen from the above embodiments, the transmission assembly 300 can convert the rotational motion output by the rotational output shaft of the drive module into linear motion, driving the clamping plate 103 to move along a straight line at the third and fourth positions. In some preferred embodiments, the transmission assembly 300 can be a gear and rack structure.

[0056] In some embodiments, the transmission assembly 300 can be an eccentric structure, specifically, as follows: Figure 11 As shown, the transmission assembly 300 includes a rotating shaft 109 and a transmission component 310; one end of the rotating shaft 109 is sleeved on the rotating output shaft, and the other end of the rotating shaft 109 is provided with an eccentric rotating shaft 1091; one end of the transmission component 310 is connected to the eccentric rotating shaft 1091, and the other end of the transmission component 310 is connected to the clamping plate 103; when the rotating output shaft of the drive module rotates, the eccentric rotating shaft 1091 can drive the transmission component 310 and the second mating part 211 to move linearly, so that the second mating part 211 moves between the third position and the fourth position.

[0057] In the above embodiments, by setting an eccentric structure in the transmission component 300, the rotational motion output by the rotational output shaft of the drive module is converted into linear motion. The transmission component 300 has a simple structure, is easy to process, and has a small size.

[0058] In some preferred embodiments, such as Figure 1 and Figure 11As shown, the first mating part 1031 can be multiple protrusions, and the second mating part 211 can be multiple grooves; or, the first mating part 1031 can be multiple grooves, and the second mating part 211 can be multiple protrusions; when the first mating part 1031 and the second mating part 211 are mated, the protrusions and grooves are mated one-to-one; or, the first mating part 1031 can be made of metal, and the second mating part 211 can be a magnet; or, the first mating part 1031 can be a magnet, and the second mating part 211 can be made of metal; when the first mating part 1031 and the second mating part 211 are mated, the magnet attracts the metal. For example, the grooves can be straight grooves, curved grooves, wavy grooves, rectangular grooves, circular grooves, or square grooves, and the protrusions are structures that match the shape of the grooves.

[0059] In some preferred embodiments, such as Figure 10 and Figure 11 As shown, the drive module may include a control module and a drive motor 106 connected to the control module. When the control module receives a clamping signal and a release signal, it controls the rotation output axis of the drive motor 106 to rotate in the corresponding direction.

[0060] In the above embodiments, the drive module has a simple structure and is relatively easy to assemble.

[0061] In some preferred embodiments, such as Figure 5 and Figure 6 As shown, the clamping end 100 is provided with a limiting element 1042 to limit the movement of the transmission component 310. The arrangement of the receiving groove limits the maximum angle that can be formed between the first component 210 and the second component 220. When the detection device 20 is clamped, when the rotary output shaft of the drive module drives the pressure plate 107 to rotate to the second position, the pressure plate 107 has already caused the first component 210 and the second component 220 to form the maximum angle, thus limiting the rotation of the rotary output end of the drive module and preventing further rotation. Figure 5 As shown, when the detection device 20 is released, when the drive module rotates to the first position, the transmission component 310 abuts against the limiting element 1042, and the rotation of the rotation output end of the drive module is restricted and can no longer continue to rotate.

[0062] In the above embodiments, by limiting the rotation position of the rotation output shaft of the drive module, the control logic of the drive module is simplified, so that the pressure plate 107 and the clamping plate 103 can reciprocate between corresponding positions without precisely controlling the rotation angle of the drive module.

[0063] In some preferred embodiments, the clamping end 100 has a detection element for detecting whether the detection device 20 is located within the receiving groove 1041, and the handheld end 110 has a display element for displaying the detection result of the detection element. Specifically, when the detection device 20 is located within the receiving groove 1041, the display element can display a first state; when the detection device 20 is not located within the receiving groove 1041, the display element can display a second state. Operators do not need to observe from a height; they can determine whether the detection device 20 is located within the receiving groove 1041 based on the state of the display element, and then perform installation and removal operations on the detection device 20 based on the determination result. This reduces the operational difficulty for operators and makes it easier for them to install and remove the detection device 20.

[0064] For example, the first state can be the light being on, and the second state can be the light being off. For example, such as... Figure 11 As shown, the detection element may include a transmitting optical fiber 10121 and a receiving optical fiber 10122 respectively disposed on both sides of the receiving groove 1041. When the detection device 20 is located within the receiving groove 1041, the receiving optical fiber 10122 cannot receive the light signal emitted by the transmitting optical fiber 10121; when the detection device 20 is not located within the receiving groove 1041, the receiving optical fiber 10122 can receive the light signal emitted by the transmitting optical fiber 10121. For example, the detection element may include an infrared emitting element and an infrared receiving element respectively disposed on both sides of the receiving groove 1041, with the same principle as described above, except that the light signal is replaced with an infrared signal. For example, the detection element may be a switching element such as an access switch, an infrared switch, or a magnetic induction switch. The operating state of the switching element differs when the detection device 20 is within the receiving groove 1041 and when it is not within the receiving groove 1041, and the operating state of the switching element can be used to determine whether the detection device 20 is within the receiving groove 1041.

[0065] In some preferred embodiments, the drive module and clamping plate 103 are located on both sides of the receiving groove 1041, and the transmission assembly 300 is located above the receiving groove 1041.

[0066] When the drive module, clamping plate 103 and transmission assembly 300 are arranged in the above manner, the structure of the entire clamping end 100 is more compact, which is conducive to meeting the design requirements of miniaturization and enhancing the competitiveness of the product.

[0067] In some preferred embodiments, the surface of the clamping plate 103 is covered with a first anti-slip layer, and the surface of the pressure plate 107 includes a second anti-slip layer. By providing the anti-slip layers, the friction between the clamping plate 103 and the pressure plate 107 is increased, thereby extending their service life.

[0068] In some preferred embodiments, such as Figure 2 and Figure 7As shown, the handheld end 110 may be equipped with a glove 111. By providing the glove 111, the coefficient of friction and friction force are increased, thus preventing slippage.

[0069] In some preferred embodiments, an insulating rod 120 of appropriate length and diameter can be customized according to the height of the drop-out fuse 30 to facilitate the installation and removal of the detection device 20 on drop-out fuses 30 at different heights.

[0070] In some preferred embodiments, the insulating rod 120 may be composed of multiple sections spliced ​​together, or the insulating rod 120 may be integrally formed, or the insulating rod 120 may be a telescopic structure.

[0071] In some preferred embodiments, the insulating rod 120 may be a hollow structure to reduce the weight of the electric clamping device 10 and facilitate user gripping and movement. The insulating rod 120 may have an inclined angle with the clamping end 100 so that the user can grip the electric clamping device 10 in the most comfortable posture, while also satisfying the inclined angle of the drop-out fuse 30 for easy installation and removal.

[0072] The structure of the electric clamping device 10 is illustrated below. It should be understood that the above structure is only one implementation method, and the electric clamping device 10 with different structures can also be formed by combining the above embodiments:

[0073] like Figure 7 As shown, the handheld end 110 includes a handle housing A113 and a handle housing B114. The handle housings A113 and B114 are tightly fitted onto the insulating rod 120 from front to back and connected together by screws or other connectors. The control module 112 is detachably installed in the mounting hole on the handle housing B114. The control module 112 is equipped with a second communication module, a clamping button, a release button, a display element in the form of an indicator light, and a button battery for power supply. A handle glove 111 is fitted onto the outer surface of the handheld end 110.

[0074] like Figure 8 As shown, the insulating rod 120 has holes at both ends for mounting the handheld end 110 and the clamping end 100. Figure 9 , Figure 10 and Figure 11As shown, the clamping end 100 includes a base 104, and a fixed base 105 is mounted on the bottom surface of the base 104.

[0076] The working principle of the electric clamping device 10 in this application is explained in detail below:

[0077] During installation, the clamping tool is placed on a horizontal surface, and the operator triggers the release button. The second communication module sends a release signal to the first communication module. After receiving the release signal, the first communication module sends it to the control module, causing the control module to control the drive motor 106 to rotate forward. When the drive motor 106 rotates forward, the pressure plate 107 rotates from the second position to the first position. The drive motor 106, in conjunction with the transmission assembly 300, drives the second mating part 211 of the clamping plate 103 to move linearly from the fourth position to the third position. Figure 5As shown, when the pressure plate 107 rotates to the first position, the rotating shaft connecting block 1010 contacts the limiting element 1042, restricting the rotation of the drive motor 106, and the second mating part 211 moves to the third position. After both the clamping plate 103 and the pressure plate 107 have moved, the operator places the detection device 20 in the receiving groove 1041. After placement, the detection element detects that the detection device 20 is located in the receiving groove 1041 and controls the display element to light up. After the operator observes the display element light up, the operator triggers the clamping button. The second communication module sends a clamping signal to the first communication module. After receiving the clamping signal, the first communication module sends the clamping signal to the control module, causing the control module to control the drive motor 106 to reverse. When the drive motor 106 reverses, the pressure plate 107 rotates from the first position toward the direction closer to the second component 220 to the second position. The drive motor 106 and the transmission component 300 work together to drive the second mating part 211 of the clamping plate 103 to move linearly from the third position toward the direction closer to the first mating part 1031 to the fourth position. Figure 6 As shown, when the pressure plate 107 rotates to the second position, the first component 210 and the second component 220 form the maximum angle, the rotation of the drive motor 106 is restricted, the pressure plate 107 presses the second component 220, and the second mating part 211 moves to the fourth position to engage with the first mating part 1031 to fix the first component 210. After the pressure plate 107 and the clamping plate 103 have both moved, the detection device 20 is clamped; then the operator holds the handheld end 110 to move the electric clamping device 10 to the drop-out fuse 30. After the movement is successful, the position of the electric clamping device 10 is adjusted so that the angle formed by the first component 210 and the second component 220 is aligned with the fuse tube 31 of the drop-out fuse 30. After alignment, the operator triggers the release button, and the second communication module sends a release signal to the first communication module. Upon receiving the release signal, the first communication module sends it to the control module, causing the control module to control the drive motor 106 to rotate forward. When the drive motor 106 rotates forward, the pressure plate 107 rotates from the second position away from the second component 220 to the first position. The drive motor 106, in conjunction with the transmission component 300, drives the second mating part 211 of the clamping plate 103 to move linearly from the fourth position away from the first mating part 1031 to the third position. When the pressure plate 107 rotates to the first position, the rotating shaft connecting block 1010 contacts the limiting element 1042, restricting the rotation of the drive motor 106, and the second mating part 211 moves to the third position. After both the clamping plate 103 and the pressure plate 107 have moved, the detection device 20 is released. After the detection device 20 is released, the first component 210 and the second component 220 clamp the fuse tube 31 under the action of the elastic element. This completes the installation operation of the detection device 20.

[0078] During disassembly, the operator triggers the release button, causing the clamping end 100, clamping plate 103, and pressure plate 107 to operate in the same manner as during installation. After operation, the operator holds the handheld end 110 and moves the electric clamping device 10 to the drop-out fuse 30. After successful movement, the position of the electric clamping device 10 is adjusted so that the detection device 20 enters the receiving groove. The detection element detects that the detection device 20 is located in the receiving groove 1041 and controls the display element to light up. After observing that the display element is lit up, the operator triggers the clamping button to clamp the detection device 20, the specific principle of which is the same as during installation. After clamping, the operator places the electric clamping device 10 on a horizontal surface. After successful placement, the operator triggers the release button to release the detection device 20, the specific principle of which is the same as in the above embodiment, and will not be repeated here. After release, the disassembly of the detection device 20 is completed.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
