[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0046] In the prior art, the inspection device includes a device body and a power taking mechanism provided on the device body. A magnetic ring is provided in the power taking mechanism and is used to sleeved on the cable to be detected. A coil is wound around the magnetic ring. When an electric current passes through the cable to be detected, an induced current can be formed on the coil through the principle of electromagnetic induction, and the induced current further flows to the corresponding module in the device body to achieve inductive power taking and cable detection.

[0047] However, the magnetic ring of the existing power taking mechanism is formed by closing two magnetic cores. The tightness of the closure of the two magnetic cores is greatly affected by external interference, resulting in unstable magnetic permeability of the magnetic ring and poor reliability of power taking and detection of the cable to be detected.

[0048] To overcome the defects in the prior art, the power taking mechanism and the inspection device provided in this application are such that the power taking mechanism forms a magnetic ring by setting a power taking structure, a detection structure, and a support assembly. The equipotential assembly abuts against the cable. Since the support assembly is provided on at least one of the magnetic cores of the power taking structure and the detection structure and is connected to the corresponding magnetic core, the first magnetic core and the second magnetic core are continuously and stably abutted against each other, ensuring stable magnetic permeability and reducing the influence of external interference on the power taking structure and the detection structure.

[0049] The content of the present utility model will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the content of the present utility model more clearly and in detail.

[0050] Refer to Figures 1 to 7 As shown, an embodiment of the present application provides a power taking mechanism for an inspection device. The power taking mechanism includes a power taking structure 100, a detection structure 200, and a support assembly 300. The power taking structure 100 has a first magnetic core 120, and the detection structure 200 has a second magnetic core 220. The power taking structure 100 and the detection structure 200 are connected so that the first magnetic core 120 and the second magnetic core 220 jointly form a magnetic ring 20 for sleeving on the cable, so as to perform electromagnetic induction with the cable through the magnetic ring 20.

[0051] The support assembly 300 is connected to the corresponding first magnetic core 120 or second magnetic core 220 so that the first magnetic core 120 and the second magnetic core 220 abut against each other.

[0052] Among them, the power-taking structure 100 and the detection structure 200 are connected so that the first magnetic core 120 of the power-taking structure 100 and the second magnetic core 220 of the detection structure 200 are in contact to form a magnetic ring 20. In this way, by respectively arranging the power-taking structure 100 and the detection structure 200 on both sides of the cable, the power-taking structure 100 and the detection structure 200 are connected and clamp the cable so that the magnetic ring 20 can be sleeved on the cable.

[0053] The power-taking structure 100 is electrically connected to the power-taking module arranged in the inspection device. When there is current passing through the cable, the current in the cable can generate an induced current in the power-taking structure 100, and the induced current flows to the power-taking related components of the inspection device to store energy for the power-taking related components and supply power to other electrical devices (such as the image acquisition device and the information communication device arranged on the inspection device, etc.) to meet the operation requirements of the inspection device.

[0054] The detection structure 200 is electrically connected to the detection related components arranged in the inspection device. When there is current passing through the cable, the current in the cable will also generate an induced current in the detection structure 200, and the induced current flows to the detection related components so that the detection related components can detect the fault of the cable operation state through the induced current to ensure the stable power transmission of the cable.

[0055] It should be noted that the power-taking structure 100 and the detection structure 200 can operate simultaneously or separately. However, since the power-taking structure 100 is used to store energy for the power-taking related components and requires a relatively large current, while the detection structure 200 is used to detect the cable operation state and requires a relatively small current, in order to avoid mutual interference when the power-taking structure 100 and the detection structure 200 operate, the power-taking structure 100 and the detection structure 200 are usually set to operate separately.

[0056] For the convenience of installing the magnetic cores, a clearance fit is usually adopted between the first magnetic core 120 and the power-taking structure 100, and between the second magnetic core 220 and the detection structure 200. Therefore, when the power-taking structure 100 and the detection structure 200 are connected, the first magnetic core 120 and the second magnetic core 220 can be driven to approach each other. However, the first magnetic core 120 and the second magnetic core 220 may not be in close contact with each other, which affects the magnetic permeability of the magnetic ring 20 formed by the first magnetic core 120 and the second magnetic core 220. Therefore, the power-taking mechanism is further provided with a support assembly 300. The support assembly 300 is arranged on at least one of the power-taking structure 100 and the detection structure 200, and is connected to at least one of the first magnetic core 120 in the power-taking structure 100 and the second magnetic core 220 in the detection structure 200, so as to push one of the first magnetic core 120 and the second magnetic core 220 towards the other, ensuring that the first magnetic core 120 and the second magnetic core 220 can be stably in contact, so that the magnetic permeability of the magnetic ring 20 formed by the first magnetic core 120 and the second magnetic core 220 is stable.

[0057] Therefore, the power-taking mechanism provided by the embodiment of the present application forms a magnetic ring 20 by arranging the power-taking structure 100, the detection structure 200 and the support assembly 300. The power-taking structure 100 and the detection structure 200 are connected to perform inductive power-taking and cable detection respectively, making the structural distribution of the power-taking mechanism more reasonable and compact. The support assembly 300 is arranged on one of the power-taking structure 100 and the detection structure 200 and is connected to the corresponding magnetic core to push the magnetic core towards the other magnetic core, so that the support assembly 300 can make the first magnetic core 120 and the second magnetic core 220 approach and abut against each other, keeping the magnetic permeability of the magnetic ring 20 stable, reducing the influence of external interference on the power-taking structure 100 and the detection structure 200, and further improving the reliability of the inspection equipment for inductive power-taking and cable detection.

[0058] In some embodiments, as shown in Figures 1 to 6 the power-taking structure 100 further includes a first housing 110 and a first coil 130. The first magnetic core 120 is arranged in the first housing 110. The first coil 130 is arranged on the first housing 110 and is magnetically conductive with the first magnetic core 120. The detection structure 200 further includes a second housing 210 and a second coil 230. The second magnetic core 220 is arranged in the second housing 210. The second coil 230 is arranged in the second housing 210 and is magnetically conductive with the second magnetic core 220.

[0059] The first housing 110 and the second housing 210 are connected so that the end faces of the first magnetic core 120 and the second magnetic core 220 are in contact. The first housing 110 and the second housing 210 jointly form a clamping space 10 for clamping the cable. The magnetic ring 20 is sleeved outside the clamping space 10;

[0060] The support component 300 is disposed in at least one of the first housing 110 and the second housing 210.

[0061] Wherein, the first magnetic core 120 is disposed in the first housing 110, and the second magnetic core 220 is disposed in the second housing 210. The first housing 110 and the second housing 210 are used to provide stable installation support for the first magnetic core 120 and the second magnetic core 220. Disposing the support component 300 in at least one of the first housing 110 and the second housing 210 can also utilize the first housing 110 and the second housing 210 to provide installation support for the support component 300, facilitating the support component 300 to drive the magnetic core to move relative to the housing. Through holes are formed in both the first housing 110 and the second housing 210. The end face of the first magnetic core 120 can extend out of the first housing 110 through the through hole, and the end face of the second magnetic core 220 can extend out of the second housing 210 through the through hole. The through holes on the first housing 110 and the second housing 210 are oppositely arranged, so as to facilitate the end faces of the first magnetic core 120 and the second magnetic core 220 to abut against each other when the first housing 110 and the second housing 210 are connected to each other, thereby forming a closed magnetic ring 20.

[0062] The first coil 130 is disposed on the first housing 110 and is magnetically conductive with the first magnetic core 120. The second coil 230 is disposed on the second housing 210 and is magnetically conductive with the second magnetic core 220. In this way, it is possible to supply power to the power taking module through the induced current in the first coil 130 and supply power to the detection module through the induced current in the second coil 230.

[0063] Wherein, the first magnetic core 120 and the second magnetic core 220 can be Figure 5 and Figure 6 shown in a semicircular shape. After the end faces of the first magnetic core 120 and the second magnetic core 220 abut against each other, a circular magnetic ring 20 is formed. In other embodiments, the first magnetic core 120 and the second magnetic core 220 can also be in a semi-rectangular shape, so that a rectangular magnetic core is formed after the end faces of the first magnetic core 120 and the second magnetic core 220 abut against each other. The present application does not limit this.

[0064] Moreover, the first housing 110 and the second housing 210 can be structures adapted to the shape of the magnetic core, or can be set as a semi-circular structure and provided with an installation space adapted to the first magnetic core 120 and the second magnetic core 220. After the first housing 110 and the second housing 210 are connected, a clamping space 10 for clamping the cable is formed between the first housing 110 and the second housing 210. The magnetic ring 20 is disposed outside the clamping space 10, which can ensure that the magnetic ring 20 can be stably sleeved on the cable.

[0065] In some embodiments, referring to Figures 1 to 6As shown, the first shell 110 includes a first containing shell 111 and a first connecting shell 112, the first magnetic core 120 is located in the first containing shell 111, and the two end surfaces of the first magnetic core 120 are located outside the first containing shell 111, the first coil 130 is wound on the first containing shell 111, and the first containing shell 111 is connected to the first connecting shell 112.

[0066] The second shell 210 includes a second containing shell 211 and a second connecting shell 212. The second magnetic core 220 is located in the second containing shell 211, and both end surfaces of the second magnetic core 220 are located outside the second containing shell 211. The second coil 230 is wound on the second containing shell 211, and the second containing shell 211 is connected to the second connecting shell 212.

[0067] The first connection shell 112 and the second connection shell 212 are connected so that the end surface of the first magnetic core 120 and the end surface of the second magnetic core 220 abut against each other.

[0068] This arrangement facilitates the installation of the magnetic core and winding of the coil, making assembly of the power supply mechanism relatively simple. During assembly, the first coil 130 is first wound on the first housing 111. After winding, the first magnetic core 120 is installed in the first housing 111, and the first housing 111 is connected to the first connecting housing 112. Similarly, the second coil 230 is now wound on the second housing 211, and the second magnetic core 220 is installed, and the second housing 211 is then connected to the second connecting housing 212.

[0069] In some embodiments, reference Figures 1 to 6 As shown, the first connecting shell 112 and the second connecting shell 212 have openings on their sides facing away from each other. The first accommodating shell 111 is arranged in the first connecting shell 112 through the opening, and the second accommodating shell 211 is arranged in the second connecting shell 212 through the opening.

[0070] The first connection shell 112 and the second connection shell 212 each have a through hole on one side facing away from the opening. The end surface of the first magnetic core 120 is located outside the first connection shell 112 through the through hole, and the end surface of the second magnetic core 220 is located outside the second connection shell 212 through the through hole.

[0071] It can be understood that the first connecting shell 112 and the second connecting shell 212 are arranged opposite to each other, and a first opening 1121 is provided on the side of the first connecting shell 112 facing away from the second connecting shell 212, and the first accommodating shell 111 is located in the first connecting shell 112 through the first opening 1121 of the first connecting shell 112, and a second opening 2121 is provided on the side of the second connecting shell 212 facing away from the first connecting shell 112, and the second accommodating shell 211 is located in the second connecting shell 212 through the second opening 2121 of the second connecting shell 212.

[0072] The first through hole 1122 of the first connecting shell 112 and the second through hole 2122 on the second connecting shell 212 are respectively located on the opposite side of the first connecting shell 112 and the second connecting shell 212. The first magnetic core 120 and the second magnetic core 220 are respectively installed in the first accommodating shell 111 and the second accommodating shell 211, and the first accommodating shell 111 and the second accommodating shell 211 are respectively provided with ports, and the peripheral side of the ports is provided with a rib. The rib at the end of the first accommodating shell 111 is connected to the first connecting shell 112 so that the port of the first accommodating shell 111 is corresponding to the first through hole 1122 on the first connecting shell 112, and the end of the second accommodating shell 211 is provided with a rib. The retaining edge is connected to the second connecting shell 212 so that the port of the second containing shell 211 is arranged corresponding to the second through hole 2122 on the second connecting shell 212, and the end of the first magnetic core 120 is exposed to the first connecting shell 112 through the port of the first containing shell 111 and the first through hole 1122 of the first connecting shell 112 in sequence, and the end of the second magnetic core 220 is exposed to the second connecting shell 212 through the port of the second containing shell 211 and the second through hole 2122 of the second connecting shell 212 in sequence, so that when the first connecting shell 112 and the second connecting shell 212 are connected, the end faces of the first magnetic core 120 and the second magnetic core 220 are pressed against each other.

[0073] The first coil 130 is wound on the first containing shell 111, and the second coil 230 is wound on the second containing shell 211. This makes it convenient to use the containing shell to provide a support structure for the coil winding, and can form a physical barrier between the coil and the magnetic core to avoid winding the coil directly on the magnetic core, thereby ensuring the stability of the magnetic field between the magnetic core and the coil, and also facilitating the heat dissipation of the coil.

[0074] In some embodiments, reference Figures 1 to 3 As shown, the support assembly 300 is arranged in the first containing shell 111, and the support assembly 300 abuts against the side of the first magnetic core 120 facing away from the second magnetic core 220; and / or, the support assembly 300 is arranged in the second containing shell 211, and the support assembly 300 abuts against the side of the second magnetic core 220 facing away from the first magnetic core 120.

[0075] It can be understood that the first magnetic core 120 is adapted to the first containing shell 111, and the second magnetic core 220 is adapted to the second containing shell 211, and the first magnetic core 120 and the second magnetic core 220 are usually gap-fitted with their respective containing shells, so the position of the magnetic core in the containing shell may be offset. When the first connecting shell 112 and the second connecting shell 212 are connected, it is difficult to ensure that the first magnetic core 120 and the second magnetic core 220 are always stably pressed together, which in turn affects the magnetic flux between the first magnetic core 120 and the second magnetic core 220, resulting in reduced stability and reliability of the inductive power supply of the first coil 130 and the cable detection of the second coil 230.

[0076] Therefore, a support assembly 300 is provided in at least one of the first housing 111 and the second housing 211. In this embodiment, the support assembly 300 is provided in the second housing 211. In other embodiments, the support assembly 300 can also be provided in the first housing 111, or support assemblies 300 can be provided in both the first housing 111 and the second housing 211.

[0077] Take Figure 3 as an example. The support assembly 300 is provided in the second housing 211, on the side of the second magnetic core 220 facing away from the first magnetic core 120. In this way, the support assembly 300 can be in contact with the side of the second magnetic core 220 facing away from the first magnetic core 120 and the side of the second housing 211 facing the first magnetic core 120 respectively. Since the second magnetic core 220 is in clearance fit with the second housing 211, and the second housing 211 is relatively fixed to the first connection shell 112 through the second connection shell 212, the support assembly 300 can push the second magnetic core 220 towards the first magnetic core 120, so that the second magnetic core 220 is in tight contact with the first magnetic core 120. Similarly, when the support assembly 300 is provided in the first housing 111, the support assembly 300 can push the first magnetic core 120 towards the second magnetic core 220, thus ensuring that the first magnetic core 120 and the second magnetic core 220 are in contact with each other.

[0078] In specific implementation, referring to Figure 3 as shown, the support assembly 300 includes at least one elastic member 310, and at least one installation portion 2111 is provided in at least one of the first housing 111 and the second housing 211.

[0079] The elastic members 310 are provided in the installation portions 2111 in one-to-one correspondence and are in contact with the corresponding first magnetic core 120 or second magnetic core 220.

[0080] By setting the support assembly 300 as at least one elastic member 310, the good elastic performance of the elastic member 310 can be utilized to ensure a continuous and stable pushing effect on the first magnetic core 120 or the second magnetic core 220, and it can prevent the support assembly 300 from over-pushing the first magnetic core 120 or the second magnetic core 220, resulting in large internal stress when the first magnetic core 120 and the second magnetic core 220 are closed.

[0081] The elastic member 310 can specifically be a helical spring, making the structure of the support assembly 300 simple and compact with low cost. In the first housing 111 or the second housing 211 where the support assembly 300 is correspondingly provided, installation portions 2111 corresponding to the number of helical springs are provided, so as to Figure 3Taking the shown as an example, the installation part 2111 is located on the side of the second accommodation shell 211 that is opposite to and away from the first accommodation shell 111. One end of the helical spring is inserted into the installation part 2111, and the other end abuts against the side of the second magnetic core 220 in the second accommodation shell 211 that is away from the first magnetic core 120, so as to provide a abutting force to the second magnetic core 220.

[0082] In other embodiments, the elastic member 310 may also be set as a rubber block, and the present application does not limit this.

[0083] And, referring to Figure 3 As shown, at least two installation parts 2111 are provided in at least one of the first accommodation shell 111 and the second accommodation shell 211, and the at least two installation parts 2111 are arranged at intervals along the extending direction of the first magnetic core 120 or the second magnetic core 220. With such an arrangement, by setting at least two installation parts 2111 at intervals, at least two elastic members 310 can be correspondingly provided on the first accommodation shell 111 or the second accommodation shell 211, so that the elastic members 310 provide multi-directional pushing forces from the back side of the magnetic core, enabling the magnetic core to stably move towards the other magnetic core, ensuring that the two magnetic cores tightly abut against each other, and guaranteeing the reliability of the power-taking mechanism operation.

[0084] In addition, in some embodiments, referring to Figures 1 to 6 As shown, the power-taking mechanism provided by the embodiment of the present application further includes a first sealing member. First sealing grooves are provided on both the first connection shell 112 and the second connection shell 212. The first sealing grooves are provided on the circumferences of the respective openings of the first connection shell 112 and the second connection shell 212, and the first sealing member is arranged in the first sealing grooves.

[0085] A first sealing groove a1123 is provided on the circumference of the first opening 1121 of the first connection shell 112, and a first sealing groove b2123 is provided on the circumference of the second opening 2121 of the second connection shell 212. Both the first connection shell 112 and the second connection shell 212 are used to connect with the shell 520 of the inspection device. By providing the first sealing grooves at the openings in this way, the openings can be in sealing fit with the shell 520 of the inspection device, avoiding moisture and impurities from entering the interiors of the first connection shell 112 or the second connection shell 212, preventing the first coil 130 and the second coil 230 from being corroded, and ensuring the stability of the power-taking mechanism.

[0086] And, referring to Figures 1 to 6 As shown, the power-taking mechanism provided by the embodiment of the present application further includes a second sealing member 400. A second sealing groove is provided on the circumference of the through hole of at least one of the first housing 110 and the second housing 210, and the second sealing member 400 is arranged in the second sealing groove.

[0087] It can be understood that when the first connecting shell 112 and the second connecting shell 212 are connected to each other, the first magnetic core 120 and the second magnetic core 220 can be pressed against each other under the action of the support assembly 300, while there is still a gap between the first connecting shell 112 and the second connecting shell 212, so that when the first magnetic core 120 and the second magnetic core 220 are actually used in the power supply mechanism, external water vapor, rainwater, snow water and other impurities can easily enter through the gap between the first connecting shell 112 and the second connecting shell 212, and directly contact the first magnetic core 120 and the second magnetic core 220, causing the first magnetic core 120 and the second magnetic core 220 to rust.

[0088] To this end, a second sealing groove a1124 can be set on the circumferential side of the first through hole 1122 of the first connecting shell 112, and a second sealing groove b2124 can be set on the circumferential side of the second through hole 2122 of the second connecting shell 212. The second sealing groove can just surround the end positions where the first magnetic core 120 and the second magnetic core 220 abut each other, so that when the first connecting shell 112 and the second connecting shell 212 are connected, the second sealing member 400 can seal the end faces where the first magnetic core 120 and the second magnetic core 220 abut each other, thereby ensuring the sealing between the first magnetic core 120 and the second magnetic core 220.

[0089] And, refer to Figure 3 As shown, the thickness of the second sealing member 400 is greater than the depth of the second sealing groove. When the first connecting shell 112 and the second connecting shell 212 are connected to each other, the sealing members on the first connecting shell 112 and the second connecting shell 212 can be pressed against each other and deformed to a certain extent, forming a sealing structure on the outside of the magnetic core. When the magnetic cores are in contact, even if water vapor impurities enter through the gap between the first connecting shell 112 and the second connecting shell 212, they cannot directly contact the magnetic core, ensuring stable and reliable contact of the magnetic cores. This further reduces the impact of external interference on the first coil 130 and the second coil 230 during operation, and improves the reliability of the power supply mechanism when performing inductive power supply and cable detection.

[0090] In a specific implementation, the wire diameter of the first coil 130 is 0.6-2.0 mm, and the number of turns of the first coil 130 is 100-500.

[0091] The wire diameter of the second coil 230 is 0.3-2.0 mm, and the number of turns of the second coil 230 is 100-1500.

[0092] It can be understood that the first coil 130 is used for inductive power taking and supplying power to the power taking module, and requires a relatively large current. The second coil 230 is used for cable detection and requires a relatively small current. Therefore, it is necessary to set the resistance of the first coil 130 to be less than that of the second coil 230. Specifically, the wire diameter of the first coil 130 can be set to 0.6 - 2.0 mm, such as 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm or 2.0 mm, and the number of turns of the first coil 130 can be set to 100 - 500 turns, such as 100, 200, 300, 400 or 500. And specifically, the wire diameter of the second coil 230 can be set to 0.3 - 2.0 mm, such as 0.3 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, 1.5 mm, 1.7 mm, 1.9 mm or 2.0 mm, and the number of turns of the second coil 230 can be set to 100 - 1500 turns, such as 100, 300, 500, 700, 900, 1100, 1300 or 1500. This application does not make specific restrictions.

[0093] Among them, when the wire diameters of the first coil 130 and the second coil 230 are the same, the resistance of the first coil 130 can be made less than that of the second coil 230 by setting the number of turns of the first coil 130 to be less than that of the second coil 230. Or when the number of turns of the first coil 130 and the second coil 230 are the same, the resistance of the first coil 130 can be made less than that of the second coil 230 by setting the wire diameter of the first coil 130 to be greater than that of the second coil 230. Or it is also possible to set the wire diameters and the number of turns of the first coil 130 and the second coil 230 to be different, and by selecting a suitable wire diameter and number of turns to cooperate, the resistance of the first coil 130 can be made less than that of the second coil 230.

[0094] In specific implementation, the second coil 230 includes a first sub - coil 231 and a second sub - coil 232. The first sub - coil 231 and the second sub - coil 232 are arranged at intervals, so as to adapt the second coil 230 to the installation part 2111 on the second accommodation shell 211, facilitate the winding of the second coil 230, and prevent interference with the installation part 2111.

[0095] Similarly, when the installation part 2111 is provided on the first accommodation shell 111, the first coil 130 can also be wound at intervals. This application does not make restrictions on this.

[0096] In addition, in some embodiments, the power taking structure 100 and the detection structure 200 are connected on the same side, and the other side of the power taking structure 100 and the detection structure 200 can be opened and closed relative to the connected side.

[0097] Specifically, the same side of the first connection housing 112 and the second connection housing 212 can be directly hinged, and the other side of the first connection housing 112 and the second connection housing 212 rotates relative to the hinge axis of the hinged side to achieve opening and closing. Or other connection structures can be provided on the same side of the first connection housing 112 and the second connection housing 212, so that the first connection housing 112 and the second connection housing 212 are connected to each other through the connection structure, and the other side of the first connection housing 112 and the second connection housing 212 away from the connection structure can be opened and closed relatively under the drive of the connection structure.

[0098] With such a setting, the power taking structure 100 and the detection structure 200 can always be connected to form a whole, and the separation or clamping of the cable is realized through the relative opening and closing of the first connection housing 112 and the second connection housing 212, making the structure of the power taking mechanism and the inspection equipment more compact and reliable, and facilitating the connection with the cable.

[0099] The embodiment of the present application also provides an inspection device, including a device body 500 and the power taking mechanism in any of the above embodiments, and the power taking mechanism is arranged in the device body 500.

[0100] Among them, the power taking mechanism has been described in detail in the above embodiments and will not be elaborated here.

[0101] The inspection device provided by the embodiment of the present application, by setting a power taking mechanism, the power taking mechanism is provided with a power taking structure 100, a detection structure 200 and an equipotential component, the power taking structure 100 and the detection structure 200 are connected to form a magnetic ring 20, and can respectively perform inductive power taking and cable detection, making the structural distribution of the power taking mechanism more reasonable and compact. The support assembly 300 is arranged on one of the power taking structure 100 and the detection structure 200 and is connected to the corresponding magnetic core to drive the magnetic core to move towards the other magnetic core, so that the support assembly 300 can drive the first magnetic core 120 and the second magnetic core 220 to approach each other, maintaining the stability of the magnetic permeability of the magnetic ring 20, reducing the influence of external interference on the power taking structure 100 and the detection structure 200, and further improving the reliability of the inspection device for inductive power taking and cable detection.

[0102] And in some embodiments, referring to Figure 7 As shown, the device body 500 includes a driving mechanism 510, both the power taking structure 100 of the power taking mechanism and the detection structure 200 of the power taking mechanism are connected to the driving mechanism 510, and the driving mechanism 510 drives the power taking structure 100 and the detection structure 200 to be connected or disconnected.

[0103] The device body 500 includes two correspondingly arranged outer shells 520. The detection structure 200 and the power-taking structure 100 are respectively arranged in the two outer shells 520. The two outer shells 520 are hinged to each other. The driving mechanism 510 is arranged on the hinged side of the two outer shells 520 and is connected to the two outer shells 520. Thus, the driving mechanism 510 can drive the two outer shells 520 to rotate relative to each other around their hinge axis. When the two outer shells 520 rotate, the corresponding power-taking structure 100 and detection structure 200 can be driven to move synchronously with their respective outer shells 520, so as to realize the connection or disconnection between the power-taking structure 100 and the detection structure 200.
