[0024] The exemplary embodiments will be described in detail herein below with reference to the drawings. The following description is merely exemplary and explanatory in nature and is not intended to limit the present disclosure, as described in the appended claims. The following description refers to the accompanying drawings wherein:

[0025] In the related art, resistance is often used to detect whether a cable is live, but distance dependence is great, and after installation and fixation, secondary calibration is required, and when the measured cable diameter changes or the distance between the sensing electrode changes, the measurement result will have a large error, and the structure of the specific device is complex, the installation and construction are more troublesome, and damage is prone to occur in actual application.

[0026] To solve the above technical problems, the detection device according to the embodiment of the present disclosure is provided, which comprises a substrate and a fixing member, and the detected object is fixed with the detection device through the cooperation of the substrate and the fixing member, so as to realize a relatively simple mounting structure, and the electric field of the detected object is inducted by an inductor coil, so as to judge whether the detected object is electrified in a non-contact manner, the equipment maintenance operation is simple, and the cost is low.

[0027] It can be understood that the detection device involved in the present disclosure can be applied to detect whether the detected object is electrified.

[0028] Figure 1 FIG. 1 is a structural schematic diagram of a detection device according to an exemplary embodiment. Figure 2 FIG. 2 is a structural schematic diagram of a detection device according to an exemplary embodiment.

[0029] In some embodiments, as shown in FIGS. 1 and 2, the detection device comprises a substrate 10, a fixing member 20 and a detection assembly. Figure 1 Figure 2 The substrate 10 can be a skeleton structure for arranging other components of the detection device, and can be used to accommodate and provide support and fixation for other components.

[0030] The substrate 10 can comprise opposite first and second faces 11 and 12.

[0031] The fixing member 20 can be a component for fixing the detection device and the detected object with each other, and the fixing member 20 can be arranged on the first face 11 and fixed with the substrate 10 to fix the detected object.

[0032] The detected object can be a conductor component, and an exemplary detected object can be a metal cable.

[0033] The detection assembly can be arranged on the second face 12, and can be used to acquire characteristics of the detected object to obtain a detection result.

[0034] The detection assembly can comprise an inductor coil 31. When the detected object is electrified with alternating current, the inductor coil 31 arranged on the detection device can induct alternating voltage change, so as to acquire the electric field change characteristics of the detected object in a non-contact manner, and the detection device obtains a detection result.

[0035] The inductor coil 31 as an element for acquiring the electric field change characteristics of the detected object has better front-end filtering effect, can better exclude the influence of interference signals on the detection result, so as to reduce the misjudgment and omission of the detection device, improve the anti-interference ability of the detection device, reduce the requirement for the computing power of the detection device, and reduce the overall power consumption and cost of the detection device.

[0036] ​​

[0037] The embodiments of the present disclosure fix the detected object and the detection device through the fixing member 20, and induct the electric field of the detected object through the inductor coil 31, so as to determine whether the detected object is charged in a non-contact manner. The installation and detection structure is simple, the equipment maintenance operation is simple, and the cost is low.

[0038] In some embodiments, as shown in Figure 1 The fixing member 20 can be detachably connected with the first surface 11 of the substrate 10, so as to facilitate the disassembly and replacement of the detection device and other maintenance operations.

[0039] When the fixing member 20 is separated from the first surface 11 of the substrate 10, the detected object can be moved between the fixing member 20 and the first surface 11 of the substrate 10. When the fixing member 20 is fixedly connected with the first surface 11 of the substrate 10, the detected object can be fixed between the fixing member 20 and the substrate 10 through the fixed relationship between the fixing member 20 and the substrate 10, so as to realize the fixation of the fixing member 20 and the substrate 10.

[0040] In some embodiments, the fixing member 20 can be detachably connected with the first surface 11 of the substrate 10 through screw connection with the first surface 11 of the substrate 10.

[0041] However, the present disclosure is not limited thereto, and the fixing member 20 can be detachably connected with the first surface 11 of the substrate 10 through one or more of a hook structure, a buckle structure, an adhesive connection structure, and a bandage structure.

[0042] Figure 3 is a structural schematic diagram of a fixing member according to an exemplary embodiment.

[0043] In some embodiments, as shown in Figure 3 The fixing member 20 can include a bottom surface 22 facing the first surface 11 and a plurality of side surfaces 23 arranged around the bottom surface 22.

[0044] The fixing member 20 can include a fixing groove 21 arranged on the bottom surface 22, and the fixing groove 21 can accommodate the detected object and constrain the movement of the detected object.

[0045] The fixing groove 21 can be a recessed groove arranged on the bottom surface 22, and the detected object can be accommodated in the fixing groove 21. The fixing groove 21 can include a first opening, and when the fixing member 20 is fixed to the first surface 11, the substrate 10 can close the first opening of the fixing groove 21 to prevent the detected object from escaping from the fixing groove 21, so as to realize the fixation of the detected object and the detection device after the fixing member 20 is fixedly connected with the substrate 10.

[0046] The two ends of the fixing groove 21 can be arranged on the opposite two sides 23 of the fixing member 20, so that the two ends of the detected object can extend from the two ends of the fixing groove 21 to the outside. For example, when the detected object is a cable, the cable can be inserted into the fixing groove 21 from one end of the fixing groove 21 and then taken out from the other end of the fixing groove 21, so as to realize the fixed connection between the detection device and the cable.

[0047] In some embodiments, the elasticity of the fixing member 20 can be greater than the elasticity of the substrate 10. For example, the fixing member 20 can be a silica gel member or a rubber member, and the substrate 10 can be a plastic member, so that the fixing member 20 can be elastically deformed to increase the pressure on the detected object and improve the fixing effect of the detection device on the detected object.

[0048] Figure 4 FIG. 1 is a structural schematic diagram of a detection device according to an exemplary embodiment.

[0049] In some embodiments, as shown in FIG. 1, the second surface 12 is provided with a receiving groove 13, and the detection assembly can include a circuit board 32 arranged in the receiving groove 13. Figure 4 The circuit board 32 can be used to arrange the circuit of the detection device. For example, the circuit board 32 can be provided with a processing circuit for processing the detection result obtained by the inductive coil 31, can include a communication circuit for communication with the outside, and can include a power supply control circuit for controlling the detection device.

[0050] The inductive coil 31 can be arranged in the receiving groove 13 and electrically connected with the circuit board 32, so that the detection result obtained by the inductive coil 31 can be transmitted to the related circuit on the circuit board 32 for processing.

[0051] The inductive coil 31 can be arranged adjacent to the projection position of the detected object on the second surface 12, so as to reduce the spatial distance between the inductive coil 31 and the detected object, thereby improving the inductive accuracy of the inductive coil 31 on the detected object, reducing the misjudgment and omission of the detection device, and improving the anti-interference ability of the detection device.

[0052] In some embodiments, the circuit board 32 can be arranged in the receiving groove 13 by screw connection, so as to realize the detachable fixing of the circuit board 32 and the substrate 10, thereby facilitating the maintenance and replacement of the circuit board 32.

[0053] In some embodiments, the detection device can further include a processing assembly and a power supply assembly, and the processing assembly can be arranged on the circuit board 32. For example, the processing assembly can be a collection of electronic components and circuits integrated on the circuit board 32.

[0054] The processing component can be used to process the detection results obtained by the inductor 31 and determine whether the detected object is charged based on the processed detection results. For example, the processing component can filter and amplify the voltage signal obtained by the inductor 31, and then extract a stable AC signal to determine whether the cable is charged due to leakage, and further determine whether there is power line leakage.

[0055] The power supply component can supply power to the processing component, so that the processing component can operate normally to maintain the normal operation of the detection device.

[0056] The processing component can also be used to detect the remaining power of the power supply component and issue a prompt when the remaining power is insufficient.

[0057] Figure 5 The figure is a schematic structural diagram of a battery box with the third cover removed according to an exemplary embodiment.

[0058] In some embodiments, as Figure 5 As shown, the power supply assembly may include a power supply box 41, in which a power supply 42 may be disposed. The power supply box 41 may provide protection and fixation for the power supply 42. The power supply box 41 may be detachably disposed on the first surface 11 of the substrate 10 to facilitate maintenance operations such as disassembly and replacement of the power supply assembly.

[0059] For example, the battery can be a disposable alkaline battery or a lithium battery module with a solar charging panel. The battery capacity can also be selected in different sizes according to the actual application environment.

[0060] The power supply 42 can be electrically connected to the processing component, thereby supplying power to the processing component so that the processing component can operate normally to maintain the normal operation of the detection device.

[0061] In some embodiments, the power supply 42 can be configured as a timer switch. The power supply 42 can supply power while the detection device is performing a detection, and can stop supplying power when the detection device completes the detection and enters a dormant state. Since the detection device is generally installed in an outdoor environment and cannot be frequently charged, the above configuration can conserve the power of the power supply 42 and reduce the power consumption of the detection device, thereby improving the battery life of the detection device, reducing the need for maintenance of the detection device due to insufficient power, and reducing the maintenance cost of replacing the power supply 42.

[0062] In some embodiments, the power box 41 can be detachably connected to the first surface 11 of the substrate 10 by screws.

[0063] However, the present disclosure is not limited thereto, and the power box 41 may also be detachably connected to the first surface 11 of the substrate 10 through one or more of a hook structure, a snap structure, an adhesive connection structure, and a strap structure.

[0064] In some embodiments, as Figure 3 As shown, the fixing member 20 can be detachably connected to the substrate 10, and the bottom surface 22 of the fixing member 20 facing the first surface 11 can be provided with a magnetic member 24. Exemplarily, the fixing member 20 can be provided with a groove matching the magnetic member 24, and the magnetic member 24 can be provided in the groove.

[0065] The circuit board 32 may be provided with a magnetically controlled switch, which may be turned on or off under the influence of the magnetic force of the magnetic member 24 .

[0066] The magnetic control switch can be connected between the power supply 42 and the processing component. When the magnetic control switch is turned on, a path can be created between the power supply 42 and the processing component, so that the power supply 42 can supply power to the processing component.

[0067] When the magnetic control switch is disconnected, the circuit between the power supply 42 and the processing component is disconnected, so that the power supply 42 can stop supplying power to the processing component.

[0068] When the fixing member 20 is connected to the substrate 10, the magnetically controlled switch is turned on by the magnetic force of the magnetic member 24, so that a path is formed between the power supply 42 and the processing component, so that the power supply 42 can power the processing component and the detection device can perform detection work normally.

[0069] When the fixing member 20 is separated from the substrate 10 , the magnetic control switch can be disconnected, thereby disconnecting the power supply 42 and the processing component, so that the power supply 42 can stop supplying power to the processing component, thereby reducing the power loss of the power supply 42 .

[0070] When the fixing member 20 is separated from the substrate 10 , it means that the detection device is separated from the object to be detected, that is, the detection device is out of the working position. At this time, the power supply 42 can stop supplying power to the processing component, which can reduce the power loss of the power supply 42 .

[0071] The magnetically controlled switch can be set at a projection position adjacent to the magnetic component 24 on the second surface 12, thereby reducing the linear distance between the magnetically controlled switch and the magnetic component 24 when the fixing component 20 is connected to the substrate 10, thereby enhancing the magnetic force of the magnetic component 24 on the magnetically controlled switch and improving the stability of the control effect of the magnetic component 24 on the magnetically controlled switch.

The power supply 42 can be electrically connected with the conductive piece 50 and transmit electric energy to the circuit board 32 through the conductive piece 50, so that the power supply 42 can supply power to the processing assembly, and the processing assembly can work normally to maintain the normal operation of the detection device.

[0075] In some embodiments, the conductive piece 50 can be a magnetic conductive terminal. One end of the conductive piece 50 can be magnetically connected with the circuit board 32, and the other end of the conductive piece 50 can be magnetically connected with the power supply 42. Configuring the conductive piece 50 as a magnetic conductive terminal can facilitate the connection and separation between the power supply 42 and the conductive piece 50 and between the conductive piece 50 and the circuit board 32, thereby simplifying the wiring arrangement of the detection device and the subsequent maintenance operations such as replacing the power supply 42 and replacing the circuit board 32.

[0076] In some embodiments, the conductive piece 50 can be provided with a foolproof design to prevent the positive and negative poles of the power supply 42 from being connected in reverse. For example, the conductive piece 50 can be a magnetic conductive terminal. The magnetic direction can prevent the positive and negative poles of the power supply 42 from being connected in reverse.

[0077] In some embodiments, as shown in Figure 6 The detection device can include a first sealing member 51. The first sealing member 51 can be arranged between the power supply box 41 and the first surface 11 and annularly arranged around the conductive piece 50, so that the first sealing member 51 can seal the gap between the power supply box 41 and the first surface 11 to prevent water vapor and dust from entering the inside of the detection device through the gap between the power supply box 41 and the first surface 11 and contacting the conductive piece 50, thereby improving the waterproof and dustproof performance of the detection device, reducing the failure of the detection device caused by water vapor and dust, and improving the durability and reliability of the detection device in outdoor scenes.

This can reduce the entry of liquid and dust and other foreign matters from the outside into the accommodating groove 13, reduce the failure of the detection device caused by water vapor and dust, and improve the durability and reliability of the detection device in outdoor scenes.

[0080] In some embodiments, the second sealing member may be a silicone ring or a rubber ring, thereby improving the sealing effect of the second sealing member.

[0081] In some embodiments, the power box 41 may be provided with a third opening, through which the power supply 42 in the power box 41 may be replaced and repaired.

[0082] The detection device may include a second cover 43 and a third seal. The second cover 43 may close the third opening of the power box 41, and the third seal may seal the gap between the second cover 43 and the third opening of the power box 41. This can reduce the entry of foreign matter such as liquid and dust into the battery compartment, reduce the possibility of malfunction of the detection device due to moisture and dust, and improve the durability and reliability of the detection device in outdoor scenarios.

[0083] In some embodiments, the third sealing member may be a silicone ring or a rubber ring, thereby improving the sealing effect of the third sealing member.

[0084] In some embodiments, as Figure 6 As shown, the detection device may include a communication component 60. Exemplarily, the communication component 60 may include multiple antennas and related communication circuits. The communication component 60 may be arranged on the circuit board 32. The communication component 60 can be used to connect to the outside world and transmit the detection results processed by the processing component and the judgment result of whether the detected object is charged to the outside world.

[0085] In some embodiments, the detection device may also include a positioning component, which can obtain the location information of the detection device itself, and when the communication component 60 transmits data, the communication component 60 can send the location information to the outside world, so that the user can be detected by the corresponding position of the detected object.

[0086] The embodiment of the present disclosure fixes the object to be detected and the detection device through a fixing member 20, and senses the electric field of the object to be detected through an inductive coil 31, thereby determining whether the object to be detected is charged in a non-contact manner. In addition, the installation and detection structure are simple, the equipment maintenance operation is easy, and the cost is low.
