[0044] The control module 9 controls the driving module 8 to drive the limiting module 7, so that the limiting module 7 is extended from the bottom of the shell 1, so as to lift the shell 1 to a certain height and separate the universal wheel 10 at the bottom of the shell 1 from the ground 101.

[0045] Furthermore, the detection module 6 includes: a current sensing unit, which is used to detect current data information of a distribution network checkpoint; an information processing unit, which is communicatively connected to the current sensing unit, and is used to convert the electrical signal of the current data information into a digital signal; an intelligent analysis unit, which is communicatively connected to the information processing unit, and the intelligent analysis unit obtains reference current data of the distribution network checkpoint based on environmental parameter information, and the intelligent analysis unit is used to dynamically set an abnormal current threshold according to the reference current data, and the intelligent analysis unit is used to determine whether the current data information exceeds the abnormal current threshold, and generate an analysis result when it is determined that the current data information exceeds the abnormal current threshold; a communication unit, which is communicatively connected to the intelligent analysis unit, and is used to transmit the analysis result to a target device.

[0046] Specifically, two different measuring points are arranged on the current sensing unit, one corresponding to the low voltage point, a Hall effect sensor for measuring the low voltage point, used to measure the load equipment end of the distribution network, and the other is a mutual inductor for measuring the high voltage and high current point, used to measure the high voltage detection point on the distribution network inspection point. Inspectors can use two different measurement modes according to actual usage to achieve higher accuracy and obtain more accurate measurement results. The signal processing unit converts the electrical signal measured by the current sensing unit into a digital signal and transmits it to the intelligent analysis unit.

[0049] By arranging a camera 42, a position sensor 43, a temperature sensor 44, a humidity sensor 45 and a wind direction sensor 46 on the supporting platform 41, real-time monitoring and collection of environmental parameters around the distribution network inspection point can be achieved for inspectors to make further judgments; at the same time, the camera records the inspection operation process of the inspectors at the distribution network inspection point in real time, which is convenient for future review and audit.

[0050] In some optional embodiments, other modules such as vibration sensors, carbon dioxide sensors, etc. can be installed on the support platform according to the actual situation of the distribution network inspection point to further protect the safety of inspectors and provide more comprehensive environmental parameter collection records of the distribution network inspection point.

[0051] Furthermore, the lifting module 5 includes: a plurality of first driving members 52, each of which is connected to the first baffle 2;

[0053] Specifically, when the telescopic column 51 is at the shortest telescopic distance, the bearing column 53 and the bearing platform 41 are in contact with each other to avoid the position displacement of the bearing platform 41 during the movement. The telescopic column 51 is driven to be telescopic by the first driving member 52, so as to achieve the effect of extending or retracting the monitoring module 4 from the shell 1. This arrangement can place the monitoring module 4 in the first receiving cavity 11 when the device is not used, which has a better protection effect and will not be interfered by external environmental factors, thus protecting the components of the monitoring module 4. When the monitoring module 4 is placed in the first receiving cavity 11, in order to avoid damaging the telescopic column 51 during the movement of the shell 1 and reducing its service life, the bearing column 53 can provide a certain degree of support to the bearing platform 41 when the telescopic column 51 is at the minimum telescopic distance, thereby protecting the overall driving lifting structure.

[0055] Specifically, the driving module 8 drives the two transmission gears 77 to drive the first transmission rod 71 and the second transmission rod 72 to rotate. During the forward rotation of the first transmission rod 71 and the second transmission rod 72, the first limiting column 73 and the second limiting column 74 are driven to extend from the bottom of the shell 1 through the first connecting member 75 and the second connecting member 76, respectively, so that the shell 1 is lifted and the universal wheel 10 at the bottom of the shell 1 is separated from the ground, thereby achieving the effect of limiting the shell 1 and avoiding the position displacement or instability of the shell 1 during the detection process; during the reverse rotation of the first transmission rod 71 and the second transmission rod 72, the first limiting column 73 and the second limiting column 74 are driven to be retracted from the bottom of the shell 1 through the first connecting member 75 and the second connecting member 76, respectively, so that the shell 1 is lowered and the universal wheel 10 at the bottom of the shell 1 is re-contacted with the ground 101, thereby restoring the movement of the shell 1, so that after the inspection is completed, the inspector can retract the shell 1 to further enhance the scene adaptability.

[0057] Specifically, the second driving member 82 is detachably connected to the bottom surface of the shell 1. The second driving member 82 drives the threaded column 81 to rise or fall, so that the transmission gear 77 meshing with it can rotate forward or reverse. The transmission method of gear meshing is used to enhance the operational stability of the equipment, avoid errors caused by vibration or movement, save space, reduce the occupied space of the shell 1, further improve the operating ability of the shell 1 in a small space, and further improve the scene adaptability of the shell 1.

[0064] In some optional embodiments, the device is further provided with: a detection door 151 adapted to the detection port 15 and used for covering the detection port 15, the detection door 151 is rotatably connected to the shell 1, a snap-fitting piece is provided on the detection door 151, a snap-fitting groove adapted to the snap-fitting piece is provided on the shell 1, the snap-fitting piece can be snap-fitted with the snap-fitting groove, and when the snap-fitting piece and the snap-fitting groove are in snap-fitting state, the detection door and the main body are in a relatively static state.

[0065] Specifically, the detection port 15 is provided with a detection door 151, which is equipped with a snap-fitting part so as to be closed in a non-detection state, thereby enhancing the safety and stability of the system and avoiding possible influence of external factors on the detection module 6 and the control module 9 inside the second receiving cavity 12.

[0066] In the specific implementation process, the task is issued by the system background, and the inspector carries the shell 1 to the designated location area of ​​the distribution network inspection point. When arriving at the designated distribution network inspection point, the inspector transmits a signal to the control module 9 through the mobile terminal on the inspector. The control module 9 controls the second driving member 82 on the driving module 8 to drive the threaded column 81 to rise, so that the threaded column 81 drives the two transmission gears 77 to rotate, thereby driving the first transmission rod 71 and the second transmission rod 72 to rotate forward, and through the first connecting member 75 and the second connecting member 76, the first limiting column 73 and the second limiting column 74 are extended from the bottom of the shell 1, so as to lift the shell 1 and make the universal wheel 10 at the bottom of the shell 1 leave the ground, thereby achieving the effect of limiting the shell 1, avoiding the position displacement or instability of the shell 1 during the detection process, and completing the preliminary preparation operation of the shell 1;

[0067] The inspector pulls the baffle 141 on the top of the shell 1 to expose the monitoring port 14, and then the control module 9 sends a control signal to make the first drive member 52 drive the telescopic column 51 to extend and retract, thereby extending the monitoring module 4 from the shell 1 and exposing the various sensors and cameras on the supporting platform 41, thereby achieving the effect of recording and collecting environmental factors at the distribution network inspection point.

[0068] During the inspection of the distribution network inspection point, the inspector opens the inspection door 151 to expose the inspection port 15, and connects the inspection line to the inspection module 6. During the connection process, the correct detection range is selected according to the characteristics of the detection line to achieve more accurate detection. During the detection process, if an abnormal current is detected, the temperature data, humidity data and wind direction data provided by the monitoring module 4 are combined with the abnormal current situation to make a preliminary analysis and determine the cause of the fault. The preliminary judgment report and abnormal current information are synchronously sent to the system background and the inspector's mobile terminal through the communication unit, so that the inspector can make a preliminary reference judgment and take the first response measures in time; after the detection is completed, the card connector on the detection door 151 is reinstalled to lock the detection door 151.

[0069] The first driving member 52 drives the telescopic column 51 to extend and retract, thereby retracting the monitoring module 4 from the outside of the shell 1 and placing the monitoring module 4 in the first receiving cavity 11, which has a better protection effect and will not be interfered by external environmental factors. The components of the monitoring module 4 are protected. When the monitoring module 4 is retracted into the first receiving cavity 11, the shielding plate 141 on the top of the shell 1 is pulled again to re-shield the monitoring port 14.

[0070] The first transmission rod 71 and the second transmission rod 72 are driven by the driving module 8. During their reverse rotation, the first limit column 73 and the second limit column 74 are driven to be retracted from the bottom of the shell 1 through the first connecting member 75 and the second connecting member 76, respectively, so that the shell 1 is lowered, and the universal wheel 10 at the bottom of the shell 1 is re-contacted with the ground, thereby restoring the movement of the shell 1, so that after the inspection is completed, the inspector can retract the shell 1 to complete the inspection work of the distribution network inspection point.

[0071] The present invention integrates multiple functions such as current monitoring, environmental monitoring (including temperature, humidity, wind direction, etc.) and visual recording (such as camera monitoring). The comprehensive monitoring system allows managers to obtain the operating status of power checkpoints from multiple dimensions to ensure that in the event of abnormal current, the impact of environmental factors is fully evaluated. For example, changes in temperature and humidity may affect the operation of the equipment. Therefore, equipment with these functions can effectively determine the cause of the abnormal current and reduce misjudgments and missed judgments.

[0072] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0073] 1. This device integrates multiple functions such as current monitoring, environmental monitoring (including temperature, humidity, wind direction, etc.) and visual recording (such as camera monitoring). The comprehensive monitoring system allows managers to obtain the operating status of power checkpoints from multiple dimensions to ensure that in the case of abnormal current, the impact of environmental factors is fully evaluated. For example, changes in temperature and humidity may affect the operation of the equipment. Therefore, devices with these functions can effectively determine the cause of abnormal current and reduce misjudgments and missed judgments.

[0074] 2. This device has a built-in intelligent analysis module, which can detect and issue an alarm notification in real time when the current is abnormal. Compared with the traditional manual inspection method, this automated design significantly improves the response speed; once the device detects that the current exceeds the set threshold, the system will immediately trigger an alarm to reduce the possibility of accidents, such as overload, current short circuit, etc., thereby ensuring the safety of equipment and personnel; in addition, the learning ability and adaptability of the intelligent analysis module enable the system to continuously optimize the threshold setting based on historical data to improve accuracy.

[0075] 3. This device fully considers the use requirements of the equipment under various climatic conditions, such as the setting of waterproof, heat dissipation and dustproof functions; the coordination of the heat dissipation hole design and the shielding parts can not only effectively prevent rain and dust from invading the interior of the device, but also enhance the heat dissipation capacity of the equipment to ensure the long-term stable operation of the equipment; in severe weather, the device can still maintain a good operating state to ensure the continued effectiveness of the monitoring function.

[0076] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0077] In addition to the above, it should be noted that "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application.
