[0045] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0046] With the continuous development of power transmission technology, the number of medium and low voltage distribution lines has continued to increase, which has increased the workload of distribution inspection personnel. For this reason, inspection devices are often installed on the distribution lines.

[0047] In the related art, the inspection device has a current sensor and a monitoring unit. The current sensor senses AC from the distribution line in a non-electrical connection manner and converts this AC into DC to supply the monitoring unit. The monitoring unit has a camera module. The camera module uses the DC provided by the current sensor to shoot the distribution line to form image data and video data, so that the distribution inspection personnel can obtain the real-time working status of the distribution line in a timely manner.

[0048] However, due to the unstable current of medium and low voltage distribution lines, especially when the current is low, the current sensor cannot achieve stable DC output, and the monitoring unit of the inspection device cannot maintain stable operation, resulting in reduced working stability of the inspection device.

[0049] In order to overcome the defects in the prior art, the present application provides a distribution line inspection device, including a shell component, an image monitor and a circuit system. The shell component and the distribution line are arranged correspondingly. The image monitor is arranged in the shell component, and the outer distribution line is photographed and monitored through the monitoring area on the shell component. The circuit system and the image monitor are electrically connected to provide power to the image monitor and ensure the stable operation of the image monitor. Among them, the circuit system includes a current sensor and a photovoltaic component. The sensing end of the current sensor faces the distribution line to sense the alternating current in the distribution line and convert the alternating current into direct current to supply the image monitor. The photovoltaic component includes a photovoltaic panel and a posture adjustment mechanism. The photovoltaic panel and the image monitor are electrically connected. The posture adjustment mechanism is arranged between the photovoltaic panel and the shell component, which can adjust the posture of the photovoltaic panel relative to the shell component and improve the photoelectric conversion efficiency of the photovoltaic panel. Through the cooperation of the current sensor and the photovoltaic component, the power supply stability of the circuit system can be improved, and then the operation of the distribution line inspection device can be stabilized.

[0050] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0051] Embodiment 1

[0052] Figure 1 A schematic diagram of the structure of a distribution line inspection device provided in Example 1 of the present application; Figure 2 An exploded diagram of the structure of the distribution line inspection device provided in Example 1 of the present application; Figure 3 for Figure 2 A partial enlarged view of part A in the figure. Figure 1-Figure 3 As shown, this embodiment provides a distribution line inspection device 100, which is arranged on the distribution line and includes a housing assembly 1, an image monitor and a circuit system.

[0053] The housing assembly 1 includes a housing member 11, which is connected to the power distribution line. The housing member 11 has a receiving cavity, and the cavity wall of the receiving cavity is at least partially light-transmissive to form a monitoring area.

[0054] The image monitor (not shown in the figure) is located in the accommodating cavity, and the monitoring end of the image monitor faces the monitoring area to capture the image of the distribution line through the monitoring area.

[0055] The circuit system includes a current sensor (not shown in the figure) and a photovoltaic assembly 2 , and both the current sensor and the photovoltaic assembly 2 are electrically connected to the image monitor.

[0056] The current sensor is located in the accommodating cavity, the sensing end of the current sensor faces the distribution line, and the current sensor is configured to sense the alternating current in the distribution line and convert it into direct current to supply to the image monitor.

[0057] The photovoltaic assembly 2 includes a photovoltaic panel 21 and a posture adjustment mechanism 22. The photovoltaic panel 21 is connected to the shell 11 through the posture adjustment mechanism 22. The posture adjustment mechanism 22 is configured to adjust the posture of the photovoltaic panel 21 relative to the shell 11. The photovoltaic panel 21 is configured to convert light energy into electrical energy and supply it to the image monitor.

[0058] Two DC power supply paths are formed between the circuit system and the image monitor in the distribution line inspection device 100 provided in this embodiment. Regardless of the size of the AC power in the distribution line, the power generated by the photovoltaic module 2 can ensure the normal and stable operation of the image monitor, thereby improving the working stability of the distribution line inspection device 100. In addition, the photovoltaic panel 21 in this embodiment adjusts the posture relative to the shell member 11 through the posture adjustment mechanism 22, changes the effective illumination area of ​​the photovoltaic panel 21, improves the photoelectric conversion efficiency of the photovoltaic panel 21, ensures the working stability of the image monitor and the distribution line inspection device 100, and can also improve the energy utilization rate of the photovoltaic module 2.

[0059] Exemplarily, the housing 11 is disposed on the distribution line. The housing 11 can be hung on the distribution line. A relatively stable fixed connection is maintained between the housing 11 and the distribution line, which can prevent relative displacement between the housing 11 and the distribution line, so that it is convenient for the staff to inspect and maintain the distribution line inspection device 100. The housing 11 has a receiving cavity, which is used to accommodate and install the image monitor and part of the circuit system. It can be understood that the image monitor and part of the circuit system are disposed in the receiving cavity, that is, the image monitor and part of the circuit system can be protected by the housing 11, so as to extend the service life of the distribution line inspection device 100.

[0060] The shell wall of the shell 11 is partially light-transmissive, forming a monitoring area. The image monitor can monitor the distribution lines outside the shell 11 through the monitoring area, so that the distribution line inspection staff can timely understand the monitoring results of the distribution line inspection device 100 on the distribution lines.

[0061] In some embodiments, the image monitor may be a camera, which is in the accommodating cavity and faces the monitoring area. The camera can shoot the distribution lines outside the accommodating cavity through the monitoring area, forming picture data and video data of the distribution line inspection. The staff can obtain these images and analyze them in time, and inspect the distribution lines. In addition, the camera in this embodiment may be a high-definition camera, a telephoto camera, a wide-angle camera, etc., so as to increase the clarity and shooting range of the pictures and videos taken as much as possible, so that the distribution line inspection staff can accurately determine the points to be inspected of the distribution line and improve the working efficiency of the distribution line inspection device 100. Of course, the camera in this embodiment may be a monocular camera or a binocular camera. It should be noted that this embodiment does not specifically limit the type of camera, and it is only necessary to ensure that the camera can shoot the distribution line through the monitoring area.

[0062] It can be understood that the distribution line inspection device 100 can also have a wireless communication module, and the wireless communication module is electrically connected to the image monitor, so that the image captured by the image monitor can be transmitted to a wireless terminal, such as a mobile phone, tablet computer and other electronic devices through the wireless communication module, thereby further improving the working efficiency of the distribution line inspection device 100.

[0063] The image monitor needs direct current to work. In this embodiment, the circuit system and the image monitor are electrically connected to provide direct current to the image monitor through the circuit system. Specifically, the circuit system includes a current sensor and a photovoltaic module 2, and the current sensor and the photovoltaic module 2 are both electrically connected to the image monitor. Among them, the current sensor is arranged in the accommodating cavity, and the sensing end of the current sensor is facing the distribution line. The current sensor can sense the alternating current in the distribution line and convert this part of the alternating current into direct current to supply the image monitor, so that the image monitor can start working. However, for medium and low voltage distribution lines, in some cases, the alternating current in the distribution line is relatively weak, resulting in a reduction in the alternating current that can be sensed by the current sensor, which cannot meet the normal and stable operation of the image monitor.

[0064] To this end, the photovoltaic assembly 2 in this embodiment is arranged on the shell member 11, and the photovoltaic assembly 2 includes a photovoltaic panel 21, the photovoltaic panel 21 is connected to the shell member 11, and the photovoltaic panel 21 is electrically connected to the image monitor, so that under the irradiation of natural light from the outside, the photovoltaic panel 21 undergoes photoelectric conversion, converts light energy into electrical energy and supplies it to the image monitor, so that the image monitor can work continuously and stably. Further, in order to improve the photoelectric conversion efficiency of the photovoltaic panel 21 and improve the electrical energy supplied by the photovoltaic panel 21 to the image monitor, the photovoltaic assembly 2 in this embodiment also includes a posture adjustment mechanism 22, and the posture adjustment mechanism 22 is arranged between the photovoltaic panel 21 and the shell member 11, that is, the photovoltaic panel 21 is connected to the shell member 11 through the posture adjustment mechanism 22. The posture adjustment mechanism 22 can change the posture of the photovoltaic panel 21 relative to the shell member 11, so that the side of the photovoltaic panel 21 facing the natural light can be exposed to as much light as possible. In this way, by adjusting the posture of the photovoltaic panel 21 relative to the shell member 11, the effective illumination area of ​​the photovoltaic panel 21 is increased, and the photoelectric conversion efficiency of the photovoltaic panel 21 and the electrical energy converted by the photovoltaic panel 21 are improved. As the electrical energy increases, the image monitor can maintain continuous and stable monitoring work, thereby ensuring the working stability of the distribution line inspection device 100.

[0065] In addition, the posture adjustment mechanism 22 adjusts the posture of the photovoltaic panel 21 relative to the housing 11, so that the photovoltaic panel 21 can avoid the monitoring area on the housing 11, so that the shooting range of the image monitor is increased, and the inspection efficiency of the distribution line inspection device 100 is improved. Furthermore, to a certain extent, the posture adjustment mechanism 22 can make the photovoltaic panel 21 fall into the shooting range of the camera, and the camera further shoots the photovoltaic panel 21, and feeds back the working status of the photovoltaic panel 21 to the distribution line inspection staff, so that the staff can understand the overall working status of the distribution line inspection device 100.

[0066] In some embodiments, the posture adjustment mechanism 22 includes a limit seat 221 and a rotating member 222, one side of the limit seat 221 is connected to the shell member 11, the limit seat 221 has a rotation cavity, the side of the limit seat 221 away from the shell member 11 has an opening connected to the rotation cavity, and at least part of the cavity wall of the rotation cavity is an arc surface; the first end of the rotating member 222 is connected to the photovoltaic panel 21, the second end of the rotating member 222 is located in the rotation cavity through the opening, the second end of the rotating member 222 matches the cavity wall shape of the rotation cavity, and the second end of the rotating member 222 is rotatably arranged relative to the cavity wall of the rotation cavity. In this embodiment, the relative movement between the limit member and the rotating member 222 realizes the adjustable posture of the photovoltaic panel 21 relative to the shell member 11, which can change the effective illumination area of ​​the photovoltaic panel 21, improve the photoelectric conversion efficiency of the photovoltaic panel 21, and further improve the electric energy converted by the photovoltaic panel 21, so as to realize the continuous and stable operation of the distribution line inspection device 100.

[0067] Specifically, the limit seat 221 is connected to the top of the shell 11, the photovoltaic panel 21 is connected to the first end of the rotating member 222 on one side of the shell 11, and the second end of the rotating member 222 extends to the limit seat 221. Relative movement is required between the second end of the rotating member 222 and the limit seat 221 to achieve adjustable posture of the photovoltaic panel 21 relative to the shell 11. Exemplarily, the limit seat 221 has a rotating cavity, the limit seat 221 is open on one side away from the shell 11, the second end of the rotating member 222 is located in the rotating cavity through the opening, and there is relative sliding between the second end of the rotating member 222 and the cavity wall of the rotating cavity, so that the second end of the rotating member 222 slides along the cavity wall of the rotating cavity in the rotating cavity, which can drive the change of the posture of the photovoltaic panel 21 relative to the shell 11.

[0068] In this embodiment, part of the cavity wall of the rotary cavity is an arc surface, and the shape of the second end of the rotating member 222 matches the cavity wall of the rotary cavity to ensure smooth movement of the rotating member 222 relative to the rotating seat 226 in the rotary cavity. Figure 2 and Figure 3 As shown, the rotating cavity in this embodiment is a spherical cavity, the rotating member 222 is spherical, and the spherical rotating member 222 is located in the rotating cavity of the rotating seat 226. The surface of the rotating member 222 and the cavity wall of the rotating cavity slide relative to each other, so as to adjust the position of the photovoltaic panel 21 relative to the shell member 11.

[0069] Of course, the rotating member 222 can also be a rod, the first end of the rod is relatively fixedly connected to the photovoltaic panel 21, and the second end of the rod matches the shape of the cavity wall of the rotating cavity. In this way, the position of the photovoltaic panel 21 relative to the shell member 11 can still be adjusted by the relative movement between the rotating member 222 and the limit seat 221.

[0070] It should be noted that the present embodiment does not impose any specific restrictions on the structure of the rotating member 222. It is only necessary to ensure that the second end of the rotating member 222 and the shape of the cavity wall of the rotating cavity of the limit seat 221 match each other to achieve relative movement between the rotating member 222 and the limit seat 221, thereby achieving adjustment of the position of the photovoltaic panel 21 relative to the shell member 11.

[0071] Furthermore, the limiting seat 221 is provided with a plurality of grooves 223, which are arranged at intervals along the circumference of the rotary cavity, and the notches of the grooves 223 face the side away from the shell member 11; the posture adjustment mechanism 22 also includes a fixing member 224, and the fixing member 224 has a connecting hole 225, and the connecting hole 225 penetrates through both sides of the fixing member 224 along the thickness direction of the fixing member 224, and the fixing member 224 is sleeved on the outer side of the limiting seat 221 through the connecting hole 225. In this embodiment, the arrangement of the grooves 223 facilitates the assembly between the rotating member 222 and the limiting seat 221, and the fixing member 224 sleeved on the outside of the limiting seat 221 can play a fixing role in the connection between the rotating member 222 and the limiting seat 221, thereby improving the structural stability of the mutual connection between the rotating member 222 and the limiting seat 221.

[0072] like Figure 2 and Figure 3 As shown, in this embodiment, there are four grooves 223, and the four grooves 223 are arranged at intervals along the circumference of the rotary cavity so that the rotating member 222 and the limit seat 221 can be assembled from all angles. In some embodiments, for example, when the rotating member 222 is a rod, the rotating member 222 can be located in the groove 223 in a certain state, and the groove wall of the groove 223 can limit the rotation of the rotating member 222, so that the position of the photovoltaic panel 21 relative to the shell member 11 can be kept in a relatively stable state. Alternatively, when the staff has adjusted the photovoltaic panel 21 to a better position through the posture adjustment mechanism 22, in order to prevent the position of the photovoltaic panel 21 relative to the shell member 11 from changing, a fixing member 224 can be set on the outside of the groove 223, and the fixing member 224 forms a force between the second end of the rotating member 222 and the cavity wall of the rotary cavity to hinder the relative movement between the rotating member 222 and the cavity wall of the rotary cavity. In this way, it can be ensured that the position of the photovoltaic panel 21 relative to the shell member 11 remains stable in a certain state.

[0073] In some cases, for example, when the rotating member 222 is a ball head structure, the rotating member 222 is at least partially located in the rotating cavity. At this time, the fixing member 224 is sleeved on the outside of the groove 223, and the surface of the ball head and the cavity wall of the rotating cavity are relatively still, which can also achieve the position of the photovoltaic panel 21 relative to the shell member 11 to remain stable in a certain state.

[0074] The fixing member 224 in this embodiment can be a metal member or a resin member, a plastic member or an elastic member, etc. The fixing member 224 can provide a certain fastening force to prevent relative movement between the rotating member 222 and the limiting seat 221 .

[0075] In a specific embodiment, the outer wall of the limit seat 221 has external threads, the connection hole 225 is a threaded hole, and the fixing member 224 is connected to the limit seat 221 through the threaded hole and the external threads. In this embodiment, the position of the photovoltaic panel 21 relative to the housing 11 is kept stable through threaded connection.

[0076] The staff can pre-adjust the position of the photovoltaic panel 21 relative to the shell 11 according to the installation position of the distribution line inspection device 100 relative to the distribution line, and through the above-mentioned implementation, the position between the photovoltaic panel 21 and the shell 11 is kept fixed, so that it is possible to avoid the blocking of the photovoltaic panel 21 by other distribution lines after the distribution line inspection device 100 and the distribution line are connected, and prevent the distribution line from causing the effective illumination area of ​​the photovoltaic panel 21 to be reduced, resulting in a decrease in the photoelectric conversion efficiency and electric energy output of the photovoltaic panel 21. In other words, through such an implementation, the photoelectric conversion efficiency and electric energy output of the photovoltaic panel 21 can be improved, thereby ensuring the stable operation of the image monitor and improving the working stability of the distribution line inspection device 100.

[0077] The photovoltaic assembly 2 in this embodiment includes a base 23, which is arranged on the side of the housing 11 away from the monitoring area, and the posture adjustment mechanism 22 is arranged between the photovoltaic panel 21 and the base 23. In this way, the photovoltaic panel 21 and the posture adjustment mechanism 22 are connected to the housing through the base 23, which facilitates the connection between the photovoltaic assembly 2 and the housing 11, so as to improve the assembly efficiency and production efficiency of the distribution line inspection device 100.

[0078] It can be understood that, based on the aforementioned embodiments, the photovoltaic panel 21, the posture adjustment mechanism 22 and the base 23 are connected in sequence to form a complete assembly component, and then the base 23 and the shell member 11 are connected. During the assembly of the distribution line inspection device 100, the posture of the photovoltaic panel 21 can be adjusted in advance by the posture adjustment mechanism 22 according to the parameters of the relative connection position between the distribution line and the distribution line inspection device 100. In this way, the photovoltaic component 2 has completed the posture adjustment during the pre-installation process, and it only needs to be fixed on the shell member 11 through the base 23. In this way, the time-consuming posture adjustment of the photovoltaic panel 21 is saved, and the production efficiency of the distribution line inspection device 100 is improved. In addition, the base 23 of the photovoltaic component 2 is arranged on the top of the shell member 11, and it can also protect the connection part between the shell member 11 and the distribution line to prevent the occurrence of dangers such as leakage in rainy days.

[0079] On the basis of the previous embodiment, the shell assembly 1 in this embodiment also includes a connector 12, which is arranged on the side of the shell member 11 away from the monitoring area. The connector 12 and the shell member 11 are spaced apart in the vertical direction and enclose a threading space 6, and the threading space 6 is configured for the distribution line to pass through; the photovoltaic component 2 is arranged on the side of the connector 12 away from the threading space 6, and the sensing end of the current sensor faces the threading space 6.

[0080] Combination Figure 1 , Figure 2 As shown, the connector 12 is arranged on the top of the shell 11, and the connector 12 and the shell 11 are spaced in the vertical direction, so as to enclose a threading space 6 through the connector 12 and the shell 11. The threading space 6 is a hollow area. The two ends of the connector 12 are relatively fixedly connected to the shell 11, and the distribution line is wrapped in the threading space 6, so that the distribution line inspection device 100 can be directly hung on the distribution line through the threading space 6. The current sensor and the threading space 6 in this embodiment are arranged correspondingly. Specifically, the current sensor is located on one side of the accommodating cavity close to the threading space 6, and surrounds the threading space 6, and the sensing end of the current sensor faces the threading space 6. When current flows in the distribution line, the current sensor can respond quickly to sense the alternating current in the distribution line, and convert this part of the alternating current into direct current to supply to the image monitor, so as to maintain the image monitor's shooting of the distribution line.

[0081] At the same time, the photovoltaic assembly 2 is arranged on the side of the connector 12 away from the threading space 6 to increase the effective illumination area of ​​the photovoltaic panel 21, increase the power output of the photovoltaic assembly 2, and supply this power to the image monitor. In this way, regardless of the current in the distribution line, the photovoltaic assembly 2 can provide power to the image monitor to ensure the stable operation of the image monitor, further improving the working stability of the distribution line inspection device 100.

[0082] The structure of the housing 11 is diverse. As a possible implementation, the housing 11 includes a first housing 11a and a second housing 11b. The first housing 11a and the second housing 11b are connected in a vertical direction and enclose a receiving cavity. The second housing 11b is a transparent member to form a monitoring area. Such a housing 11 facilitates the installation of the image monitor and the circuit system and the protection of the image monitor and the circuit system.

[0083] It can be understood that the first shell 11a and the second shell 11b are connected in the vertical direction, and the inner walls of the first shell 11a and the second shell 11b together form a closed accommodating cavity, and the image monitor and part of the circuit system are arranged in the accommodating cavity. When the distribution line inspection device 100 is in an outdoor environment, the closed accommodating cavity can protect the image monitor and part of the circuit system, thereby extending the service life of the distribution line inspection device 100. At the same time, it can also prevent the occurrence of electrical connection short circuits and other safety accidents caused by rainy and snowy weather, thereby ensuring the operation safety and stability of the distribution line inspection device 100.

[0084] On this basis, the second shell 11b in this embodiment is a transparent part, that is, the second shell 11b forms a monitoring area, and the image monitor shoots the external distribution line through the second shell 11b to form picture data and video data of the distribution line inspection. In addition, the wall surface of the second shell 11b in this embodiment is an arc surface, and the arc surface is protruded in the vertical direction relative to the first shell 11a, which can increase the area of ​​the monitoring area, which is conducive to the image monitor to inspect and shoot the external distribution line through the monitoring area, and such a shell 11 has a certain aesthetics.

[0085] As described above, the distribution line inspection device 100 provided in this embodiment is arranged on the distribution line, and includes a housing component 1, an image monitor and a circuit system. The housing component 1 includes a housing member 11, the housing member 11 is connected to the distribution line, the housing member 11 has a receiving cavity, and the shell wall of the housing member is at least partially transparent to form a monitoring area. The image monitor is located in the receiving cavity, and the monitoring end of the image monitor faces the monitoring area, and the image of the distribution line is captured through the monitoring area. The circuit system includes a current sensor and a photovoltaic component 2, the current sensor and the photovoltaic component 2 are both electrically connected to the image monitor, the current sensor is located in the receiving cavity, the sensing end of the current sensor faces the distribution line, and the current sensor is configured to sense the alternating current in the distribution line and convert it into direct current to supply to the image monitor; the photovoltaic component 2 includes a photovoltaic panel 21 and a posture adjustment mechanism 22, the photovoltaic panel 21 is connected to the housing member 11 through the posture adjustment mechanism 22, the posture adjustment mechanism 22 is configured to adjust the posture of the photovoltaic panel 21 relative to the housing member 11, and the photovoltaic panel 21 is configured to convert light energy into electrical energy and supply it to the image monitor. Through such a structural setting, the stability of the circuit system supplying power to the image monitor is ensured, so that the image monitor can maintain stable monitoring work, thereby improving the working stability of the distribution line inspection device 100.

[0086] Embodiment 2

[0087] The distribution line inspection device 100 in this embodiment is basically the same in structure and working principle as the distribution line inspection device 100 provided in the above-mentioned embodiment 1, except that the posture adjustment mechanism 22 in the photovoltaic module 2 has a different posture adjustment method for the photovoltaic panel 21. The posture adjustment mechanism 22 in the distribution line inspection device 100 provided in this embodiment is described in detail below in conjunction with the accompanying drawings. It should be noted that the other structures in the distribution line inspection device 100 provided in this embodiment have been described in detail in the above-mentioned embodiment 1, and will not be repeated in this section.

[0088] Figure 4 This is a schematic diagram of the structure of the distribution line inspection device provided in Example 2 of the present application. Figure 5 This is an exploded diagram of the structure of the distribution line inspection device provided in Example 2 of the present application.

[0089] like Figure 4 and Figure 5 As shown, the posture adjustment mechanism 22 in this embodiment includes a rotating seat 226 and a bracket 227. The photovoltaic panel 21, the bracket 227, the rotating seat 226 and the shell member 11 are connected in sequence. The rotating seat 226 is rotatably arranged relative to the shell member 11 around a first rotating axis, and the bracket 227 is rotatably arranged relative to the rotating seat 226 around a second rotating axis; wherein the first rotating axis and the second rotating axis intersect.

[0090] Specifically, the rotating seat 226 is disposed on the top of the housing 11, and the rotating seat 226 rotates relative to the housing 11 around a first rotation axis, and the first rotation axis is in the vertical direction. The bracket 227 is connected to the rotating seat 226, and the bracket 227 rotates relative to the rotating seat 226 around a second rotation axis, and the second rotation axis is in the horizontal direction. The photovoltaic panel 21 and the bracket 227 are relatively fixedly connected, and the photovoltaic panel 21 and the bracket 227 can be relatively stably fixedly connected by bonding or clamping, etc., and this embodiment does not limit this.

[0091] The rotating seat 226 rotates relative to the housing 11 around the first rotation axis, and the rotating seat 226 drives the bracket 227 and the photovoltaic panel 21 to rotate around the first rotation axis. When the bracket 227 rotates relative to the rotating seat 226 around the second rotation axis, the bracket 227 drives the photovoltaic panel 21 to rotate around the first rotation axis. In this way, the posture adjustment mechanism 22 can also achieve the adjustable posture of the photovoltaic panel 21 relative to the housing 11, change the effective illumination area of ​​the photovoltaic panel 21, and improve the photoelectric conversion efficiency and electrical energy output of the photovoltaic panel 21, so that the image monitor maintains a stable working state.

[0092] In this embodiment, the driving mode of the rotating seat 226 rotating around the first rotation axis relative to the shell member 11 and the bracket 227 rotating around the second rotation axis relative to the rotating seat 226 can be manually driven or realized by a power control structure. For example, the relatively connected part of the rotating seat 226 and the shell member 11 can be provided with a circular track, and the rotating seat 226 and the shell member 11 can realize the rotation of the rotating seat 226 relative to the shell member 11 around the first rotation axis through the relative rotation between the circular track. In order to make the relative movement between the rotating seat 226 and the shell member 11 controllable, damping can be set in the sliding track, and the damping is used to hinder the rotation of the rotating seat 226 relative to the shell member 11 around the first rotation axis. It can be understood that after the posture of the photovoltaic panel 21 is adjusted to the preset position, the relative movement between the rotating seat 226 and the shell member 11 can avoid the change of the posture of the photovoltaic panel 21 caused by the relative movement. Correspondingly, the rotating connection structure between the bracket 227 and the rotating seat 226 can also be adopted in this way.

[0093] It can be understood that in this embodiment, the first rotation axis and the second rotation axis are perpendicular to each other.

[0094] Of course, as one of the embodiments, the posture adjustment mechanism 22 also includes a first drive assembly, the first drive assembly is connected to the rotating seat 226, the first drive assembly includes a first motor 3a, and the first motor 3a is configured to drive the rotating seat 226 to rotate relative to the housing 11 around the first rotation axis; and / or, the posture adjustment mechanism also includes a second drive assembly, the second drive assembly is connected to the bracket 227, the second drive assembly includes a second motor 3b, and the second motor 3b is configured to drive the bracket 227 to rotate relative to the rotating seat 226 around the second rotation axis. In this way, the position and posture of the photovoltaic panel 21 relative to the housing 11 are adjustable by setting the first motor 3a and the second motor 3b to output circular motion.

[0095] In this embodiment, the first driving assembly includes a first motor 3a, and the first motor 3a and the rotating seat 226 are correspondingly arranged. It can be understood that the first motor 3a can be connected to the housing 11, and the output shaft of the first motor 3a faces one side of the rotating seat 226. The output shaft of the first motor 3a rotates around the first rotation axis, and the rotating seat 226 can be driven to rotate relative to the housing 11 around the first rotation axis. Correspondingly, the second driving assembly includes a second motor 3b, and the second motor 3b and the bracket 227 are correspondingly arranged. The second motor 3b can be connected to the rotating seat 226, and the output shaft of the second motor 3b faces one side of the bracket 227. The output shaft of the second motor 3b rotates around the second rotation axis, thereby driving the bracket 227 to rotate relative to the rotating seat 226 around the second rotation axis. In this way, the position of the photovoltaic panel 21 relative to the housing 11 is adjusted by driving the first motor 3a and the second motor 3b, and the effective illumination area of ​​the photovoltaic panel 21 is changed, so that the photovoltaic assembly 2 can stably supply power to the image monitor, thereby improving the working stability of the distribution line inspection device 100.

[0096] In the specific implementation process, the first motor 3a and the second motor 3b can be servo motors, which can control the speed and stroke of the servo motors through servo instructions to accurately adjust the posture of the photovoltaic panel 21 and ensure that the external environment does not block the photovoltaic panel 21 as much as possible, thereby improving the photoelectric conversion efficiency and electrical energy output of the photovoltaic panel 21 and ensuring the stable operation of the distribution line inspection device 100.

[0097] Specifically, the first driving assembly further includes a first transmission gear set, the first motor 3a is connected to the rotating seat 226 through the first transmission gear set, and drives the first transmission gear set to drive the rotating seat 226 to rotate around the first rotation axis relative to the housing 11; and / or, the second driving assembly further includes a second transmission gear set, the second motor 3b is connected to the bracket 227 through the second transmission gear set, and drives the second transmission gear set to drive the bracket 227 to rotate around the second rotation axis relative to the rotating seat 226. In this way, the stability and smoothness of motion transmission are ensured by the connection between the motor and the gear set.

The first motor 3a is connected to the first transmission gear set to drive the first transmission gear set to drive the rotating seat 226 to rotate relative to the housing 11 around the first rotation axis.

[0099] Specifically, the first transmission gear group includes a first driving gear 4a and a first driven gear 5a, and the first driving gear 4a and the first driven gear 5a are meshed and transmitted with each other, wherein the first driving gear 4a and the output shaft of the first motor 3a are connected through a hole shaft key, and the first driven gear 5a and the bottom of the body 226a are relatively fixedly connected. The first motor 3a is started and outputs circular motion through the output shaft, and the rotating seat 226 is rotated around the first rotation axis through the meshing transmission of the first transmission gear group.

[0100] In this embodiment, the side of the body 226a facing away from the base 23 is connected with an exterior decoration 226b, and the exterior decoration 226b and the body 226a together form a mounting cavity, and the side of the mounting away from the exterior decoration 226b is opened, and the bracket 227 is connected to the body 226a through the opening, and the bracket 227 rotates around the second rotation axis relative to the body 226a. Similarly, the second drive assembly is connected to the bracket 227, and the second drive assembly is located in the mounting cavity. Specifically, the second motor 3b can be connected to any one of the body 226a or the exterior decoration 226b, and the output shaft of the second motor 3b faces one side of the bracket 227. The second motor 3b is connected to the second transmission gear set to drive the bracket 227 to rotate relative to the rotating seat 226 around the second rotation axis. The second transmission gear includes a second driving gear 4b and a second driven gear 5b, the second driving gear 4b and the second motor 3b are connected by a hole shaft key, the second driven gear 5b and the bracket 227 are connected to one side of the exterior decoration 226b, and the second driven gear 5b and the second driving gear 4b are meshed for transmission.

In this embodiment, the position adjustment of the photovoltaic panel 21 relative to the shell 11 is achieved through the mutual cooperation of the above-mentioned first drive assembly and the second drive assembly. It should be noted that the transmission ratio of the first transmission gear set and the second transmission gear set can be selected according to actual needs.

[0101] The distribution line inspection device 100 provided in this embodiment controls the movement of the posture adjustment component according to the position of the distribution line and the mounting position of the distribution line inspection device 100 relative to the distribution line during the specific practice, so as to avoid the external environment from blocking the photovoltaic panel 21, or to enable the photovoltaic panel 21 to always face the south direction to improve the efficiency of natural lighting. In this way, the photoelectric conversion efficiency and the output electric energy of the photovoltaic panel 21 can be improved, thereby ensuring the working stability of the distribution line inspection device 100.

[0102] Furthermore, the photoelectric conversion efficiency of the photovoltaic panel 21 varies with the longitude and latitude and the change of the sunshine time in the four seasons.
