Description

Technical Field

[0001] The utility model relates to the technical field of cable fault location, in particular to a photovoltaic cable fault location device applied to a photovoltaic power station. Background Art

[0002] The photovoltaic cable fault location device has important functions in many aspects. First of all, it can quickly detect faults, rapidly discover problems such as short circuits, open circuits, and insulation damage in photovoltaic cables, and shorten the fault troubleshooting time. For example, when a certain section of photovoltaic cable is short-circuited due to external factors, the device can quickly locate the approximate position of the short-circuit point, avoiding blind searching by staff. Secondly, it helps to improve the operation and maintenance efficiency, helps operation and maintenance personnel accurately find the fault point, and reduces unnecessary inspections and tests.

[0003] Traditional photovoltaic cable fault location devices usually consist of several main mechanisms. Among them, the signal transmitting mechanism is responsible for sending specific detection signals to the photovoltaic cable. These signals can be current, voltage, or other specific electromagnetic waves, etc. For example, high-frequency pulse current signals are sent to detect the fault conditions of the cable. The signal receiving and collecting mechanism is used to receive the signals returned from the photovoltaic cable and collect and process them. This part of the mechanism usually includes high-precision sensors and data acquisition cards, etc. The data analysis and processing mechanism analyzes and calculates the collected signals to determine whether there is a fault in the cable and the type and location of the fault. Common data analysis methods include time-domain reflectometry, frequency-domain reflectometry, etc.

[0004] However, traditional photovoltaic cable fault location devices have an obvious defect, that is, the height cannot be adjusted. When facing photovoltaic cable layouts at different heights, due to the fixed height of the device, it is impossible to accurately approach the cable for detection, thus affecting the accuracy of the detection signal and the precision of fault location. The inability to adjust the height limits the adaptability of the device in complex terrains and special installation environments. In some areas with uneven terrain or obstacles, the device with a fixed height cannot reach the appropriate detection position, increasing the difficulty and time cost of the detection work. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a photovoltaic cable fault location device applied to a photovoltaic power station, aiming to improve the problem that the height cannot be adjusted in the prior art, resulting in the inability to adapt to various working environments.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 and Figure 2 A photovoltaic cable fault location device applied to a photovoltaic power station includes a bottom plate 2. A slide block plate 3 is fixedly connected to the top of the bottom plate 2. A first support plate 6 is fixedly connected to the top of the slide block plate 3. A first hydraulic cylinder 7 is fixedly connected to the top of the first support plate 6. The output end of the first hydraulic cylinder 7 is fixedly connected to a connecting block 10. A hollow plate 9 is slidably connected inside the connecting block 10;

[0026] The bottom of the hollow plate 9 is fixedly connected to the top of the slide block plate 3. A first fixing plate 13 is fixedly connected to the side wall of the slide block plate 3. A second connecting plate 12 is rotatably connected to the inner wall of the first fixing plate 13. One end of the second connecting plate 12 is rotatably connected to a first connecting plate 11. A second support plate 8 is rotatably connected to the side wall of the first connecting plate 11. The top of the second support plate 8 is fixedly connected to a top plate 4.

[0027] Specifically, when using the photovoltaic cable fault locating device, firstly, the output end of the first hydraulic cylinder 7 exerts its powerful driving force to drive the connecting block 10 to slide smoothly and steadily inside the hollow plate 9. The force borne by the connecting block 10 will effectively drive the first connecting plate 11 to rotate in an effective transmission manner. Then, under the action of the force, the first connecting plate 11 rotates on the side wall of the second connecting plate 12 in a precise and orderly manner. The second connecting plate 12 also rotates smoothly and stably on the side wall of the first fixing plate 13 under the action of the force, and the first connecting plate 11 rotates accurately on the inner wall of the second supporting plate 8, achieving the ideal effect of flexible height adjustment.

[0028] Reference Figure 1 and Figure 3 A mechanical arm 5 is fixedly connected to the top of the top plate 4, a second fixed plate 15 is fixedly connected to one side of the mechanical arm 5, a hollow block 16 is fixedly connected to one side of the second fixed plate 15, a third fixed plate 17 is slidably connected inside the hollow block 16, a connecting rod 20 is rotatably connected to the side wall of the third fixed plate 17, and a side wall of the connecting rod 20 is rotatably connected to the side wall of the third fixed plate 17;

[0029] The side wall of the third fixed plate 17 is fixedly connected with a clamping plate 19 , and the side wall of the third fixed plate 17 is rotatably connected to the side wall of the support block 18 . One side of the robot arm 5 is fixedly connected with the second hydraulic cylinder 14 , and the output end of the second hydraulic cylinder 14 is fixedly connected with the support block 18 .

[0030] Specifically, the mechanical arm 5 can achieve multi-directional position adjustment, which provides great flexibility and convenience for subsequent operations. The output end of the second hydraulic cylinder 14 drives the support block 18 to move. The second hydraulic cylinder 14 can output strong and stable power to ensure that the support block 18 moves accurately in a predetermined direction and distance. The movement of the support block 18 drives the connecting rod 20 to rotate. This rotation is an orderly and coordinated movement, which lays the foundation for subsequent actions. The force of the support block 18 drives the third fixed plate 17 to slide, and the third fixed plate 17 slides inside the hollow block 16. The hollow block 16 provides a stable track and space for the sliding of the third fixed plate 17. Moreover, the hollow block 16 is fixedly connected to the side wall of the mechanical arm 5 through the second fixed plate 15, achieving the effect of clamping the cable.

[0031] Reference Figure 1 A moving component is arranged at the bottom of the base plate 2, and the moving component is used to control the rapid movement function of the device. The moving component includes a wheel 1, and the top of the wheel 1 is fixedly connected to the bottom of the base plate 2.

[0032] Specifically, by pushing the top plate 4, the force applied to the top plate 4 is effectively transmitted to the bottom wheels 1. After the wheels 1 receive the force from the top plate 4, they start to rotate under the force. Due to the rotation characteristics of the wheels 1 and the relatively small frictional force between them and the contact surface, the entire device can move smoothly under the action of the force. The transmission of this force and the rotation of the wheels 1 cooperate with each other to achieve the effect of rapid movement, greatly improving the mobility and convenience of the device.

[0033] Working principle: When using the photovoltaic cable fault location device, first, the output end of the first hydraulic cylinder 7 drives the connecting block 10 to slide inside the hollow plate 9. The force on the connecting block 10 drives the first connecting plate 11 to rotate. The force on the first connecting plate 11 causes it to rotate on the side wall of the second connecting plate 12, and the second connecting plate 12 rotates on the side wall of the first fixing plate 13. Moreover, the first connecting plate 11 rotates inside the inner wall of the second support plate 8, achieving the effect of height adjustment.

[0034] The force on the top plate 4 drives the bottom wheels 1, and the wheels 1 rotate under the force, achieving the effect of rapid movement. The position can be adjusted in multiple directions through the robotic arm 5. The output end of the second hydraulic cylinder 14 drives the support block 18 to move. The movement of the support block 18 drives the connecting rod 20 to rotate. The force on the support block 18 drives the third fixing plate 17 to slide, and the third fixing plate 17 slides inside the hollow block 16. Moreover, the hollow block 16 is fixedly connected to the side wall of the robotic arm 5 through the second fixing plate 15, achieving the effect of clamping the cable.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
