Description

Technical Field

[0001] The present invention relates to the technical field of power leakage detection, and more specifically, to a power grid power leakage detection and monitoring device. Background Art

[0002] In the field of cross-regional power grid power transmission of modern power grids, underwater cables are key infrastructure for power grid cross-water power transmission and networking, especially playing an irreplaceable role in fields such as offshore wind power and island power supply. Therefore, underwater cables are specially designed to transmit electrical energy or communication signals in an underwater environment and have special waterproof, pressure-resistant, corrosion-resistant, and anti-mechanical damage structures to adapt to the complex underwater environment underwater cables underwater.

[0003] Since underwater cables are laid in rivers, lakes, straits, or the seabed, it is inconvenient to manually detect the leakage of underwater cables. Therefore, the prior art uses underwater robots to conduct inspections along the laying direction of underwater cables. The underwater robots are equipped with high-definition cameras and multi-spectral sensors to identify sheath damage, mechanical damage, or foreign object entanglement of underwater cables. They are also equipped with an electromagnetic detection module to locate current leakage points caused by insulation damage by measuring the magnetic field distribution around the underwater cable. Generally, an infrared temperature measurement module is also equipped to assist in detecting the surface temperature distribution of the underwater cable. Local overheating indicates leakage or poor contact at that part.

[0004] The detection end of the underwater robot needs to maintain the best detection distance from the underwater cable. For example, the high-definition camera needs to maintain a stable distance within the range of 0.5 to 2 meters. If the distance is too far, the image will be blurred. If the distance is too close, side damage may be missed due to limited viewing angles. The effective detection distance of the electromagnetic sensor is usually below 0.5 meters. Beyond this range, the signal will attenuate severely, resulting in missed detection of minor defects. Since the infrared thermal imager has a temperature compensation system, it needs to be detected at a fixed height of 0.5 meters (±0.1). Getting too close to or too far from the cable will cause the temperature compensation system to fail. Therefore, the best detection distance of the underwater robot is 0.5 meters. However, when the laying section of the underwater cable is a slope, during the uphill process, the head of the underwater robot needs to be kept upward, and the overall underwater robot tends to move away from the underwater cable due to the water flow pressure in the front. During the downhill process, the head of the underwater robot needs to be kept downward, and the overall underwater robot tends to move closer to the underwater cable due to the water flow pressure in the front. Therefore, when there are many steep slopes or pits in the underwater environment, the laying of the underwater cable is wavy, and the detection route of the underwater robot is also wavy. The acting forces generated by multiple uphill and downhill movements cause the underwater robot to deviate from the best detection distance. Therefore, when detecting the laying section with height changes of the underwater cable, the underwater robot needs to actively adjust its height multiple times, affecting the positioning accuracy of the underwater robot and reducing the detection efficiency. Summary of the Invention

[0005] A power grid power leakage detection and monitoring device provided by the present invention aims to solve the following problem: for existing power grid power leakage detection and monitoring devices, in laying sections with frequent height changes, the underwater robot needs to actively adjust its height multiple times, which affects the positioning accuracy of the underwater robot and reduces the detection efficiency.

Detailed implementation manners

[0030] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0031] Refer to the accompanying drawings of the specification Figures 1 to 8, a power grid power leakage detection and monitoring device, including an inspection mechanism 1. A guiding mechanism 2 is provided at the output end of the inspection mechanism 1. A connecting rod 3 is rotatably connected between the inspection mechanism 1 and the guiding mechanism 2. A cable 4 is provided below the guiding mechanism 2, and the guiding mechanism 2 moves along the axial direction of the cable 4; The inspection mechanism 1 includes a housing 11. A machine head seat 12 is installed at one end of the housing 11 corresponding to the connecting rod 3. A connection box 13 is installed on the machine head seat 12. A limiting piece 131 is movably arranged on the connection box 13. An ejecting mechanism is installed inside the connection box 13, and the ejecting mechanism is used to drive the limiting piece 131 to move. An extension piece 33 is installed at one end of the connecting rod 3 corresponding to the connection box 13; A clamping mechanism 5 is installed at the bottom of the guiding mechanism 2. The clamping mechanism 5 includes a first support seat 51 and a second support seat 55, and the first support seat 51 and the second support seat 55 are respectively arranged at both ends of the bottom of the guiding mechanism 2. Main clamping wheels 52 are installed on both the first support seat 51 and the second support seat 55. Auxiliary frames 53 are installed on both the first support seat 51 and the second support seat 55, and two groups of auxiliary frames 53 are arranged oppositely. Auxiliary clamping wheels 54 are installed on the auxiliary frames 53. The main clamping wheels 52 are arranged on one side of the top of the cable 4, and the auxiliary clamping wheels 54 are arranged on one side of the bottom of the cable 4. A reverse driving component is installed on the first support seat 51, and the reverse driving component is used to drive the two groups of auxiliary frames 53 on the first support seat 51 to approach or move away from each other; Connection frames 31 and right-angle plates 32 are respectively arranged at both ends of the connecting rod 3. The connection frame 31 is installed on the guiding mechanism 2. Two parallel cross bars are arranged on the connection frame 31, and one end of the connecting rod 3 is rotatably connected to one of the cross bars. The right-angle plate 32 is installed on the connection box 13.

[0032] It should be noted that the connecting rod 3 is in an inclined state. When the guiding mechanism 2 detects in a section with a small height change, taking the cable 4 as the horizontal reference line, the included angle between the connecting rod 3 and the cable 4 is between 60 - 90 degrees. The cable 4 is between the main clamping wheel 52 and the auxiliary clamping wheel 54. Two groups of right-angle plates 32 are provided, and a cross shaft is fixedly arranged between the two groups of right-angle plates 32. One end of the connecting rod 3 away from the connection frame 31 is rotatably connected to the cross shaft. The connection frame 31 is arranged at one end of the guiding mechanism 2, and the connecting rod 3 is connected to the cross bar on the side away from the installation chamber two 22.

[0033] In this embodiment, the implementation scenario is specifically as follows: The whole is vertically put into the water downward. At this time, the inspection mechanism 1 pushes one end of the guiding mechanism 2 corresponding to the connecting frame 31 through the connecting rod 3, so that the second support base 55 first abuts against the cable 4, and the cable 4 is clamped between the main clamping wheel 52 and the auxiliary clamping wheel 54 of the second support base 55. Since one group of cross bars of the connecting rod 3 is rotatably connected to the connecting frame 31, the other cross bar plays a role of limiting and blocking. At this time, the guiding mechanism 2 and the connecting rod 3 are in a V shape. Then, the inspection mechanism 1 is adjusted to a horizontal state. At this time, the reverse driving assembly drives the two auxiliary frames 53 of the first support base 51 to move away from each other, so that the main clamping wheels 52 and the auxiliary clamping wheels 54 on both sides move away until the guiding mechanism 2 is in a horizontal state. The reverse driving assembly drives the two auxiliary frames 53 of the first support base 51 to approach each other, so that the main clamping wheels 52 and the auxiliary clamping wheels 54 on both sides of the first support base 51 clamp the cable 4. That is, the whole first "hardly" clamps the main clamping wheel 52 and the auxiliary clamping wheel 54 at the second support base 55 on both sides of the cable 4 through the driving force of the inspection mechanism 1, and then the main clamping wheel 52 and the auxiliary clamping wheel 54 at the first support base 51 are driven by the reverse driving assembly to open and approach automatically and clamp on both sides of the cable 4. Finally, the guiding mechanism 2 is installed in place. The ejecting mechanism drives the limiting piece 131 to extend out of the connection box 13 to limit the extension piece 33 at one end of the connecting rod 3, so as to limit the inclination angle of the connecting rod 3. At this time, the whole runs as shown in Figure 1 the attached state. Through the guidance of the guiding mechanism 2 and the connecting rod 3, when the laying height of the cable 4 changes frequently, the guiding mechanism 2 drives the inspection mechanism 1 to passively change the height through the connecting rod 3, so as to overcome the acting force generated by the inspection mechanism 1 for multiple uphill and downhill movements, keep the inspection mechanism 1 at the best detection distance, without positioning the distance between the inspection mechanism 1 and the cable 4 multiple times, ensure the positioning accuracy of the inspection mechanism 1, thus shortening the detection time and improving the detection efficiency, and reducing the power consumption caused by multiple active adjustments of the inspection mechanism 1.

[0034] Further, a clamping plate 511 is fixedly arranged on the first support base 51. A sliding groove 512 is formed on the first support base 51. A T-shaped seat 531 is fixedly arranged at the bottom of the auxiliary frame 53, and the T-shaped seat 531 is slidably arranged between the clamping plate 511 and the sliding groove 512. A second guiding column 532 is fixedly arranged on one side of the auxiliary frame 53. Guiding cylinders 533 are installed at both ends of the first support base 51, and the second guiding column 532 penetrates through the corresponding guiding cylinder 533.

[0035] It should be noted that the clamping plate 511 is fixed on both sides of the sliding groove 512 to form a clamping groove. Both sides of the horizontal plate of the T-shaped seat 531 are clamped into the clamping groove and slide along the direction of the clamping groove. The second guiding column 532 and the guiding cylinder 533 play a guiding role.

[0036] Further, an L-shaped piece 541 is installed on the auxiliary frame 53, the auxiliary clamping wheel 54 is rotatably installed on the L-shaped piece 541, an elastic member 542 is fixedly provided between the L-shaped piece 541 and the auxiliary frame 53, and the auxiliary clamping wheel 54 is located obliquely below the main clamping wheel 52.

[0037] It should be noted that the L-shaped piece 541 is elastically supported by the elastic member 542. When the auxiliary clamping wheel 54 is under pressure, it can provide a buffer space for the L-shaped piece 541. During the process of the cable 4 being clamped between the main clamping wheel 52 and the auxiliary clamping wheel 54, the two groups of auxiliary clamping wheels 54 respectively compress the corresponding elastic members 542, making the two groups of auxiliary clamping wheels 54 in a V-shape for easy clamping of the cable 4. Similarly, when the cable 4 disengages from between the main clamping wheel 52 and the auxiliary clamping wheel 54, the auxiliary clamping wheel 54 stretches the elastic member 542 for easy pulling out of the cable 4.

[0038] Further, a bottom plate 23 is installed at the bottom of the guiding mechanism 2. The reverse driving assembly includes a second driver 212, and the second driver 212 is fixedly provided on the bottom plate 23. Side brackets 213 are installed on both sides of the bottom plate 23. The output end of the second driver 212 is connected to a lead screw 214. A first guiding post 215 is provided on one side of the lead screw 214. A movable seat 216 is installed on the lead screw 214, and the movable seat 216 is fixedly connected to the T-shaped seat 531.

[0039] It should be noted that an opening is also provided on the first support seat 51. The movable seat 216 passes through the opening through an L-shaped plate to fixedly connect to the corresponding T-shaped seat 531. The second driver 212 drives the lead screw 214 to rotate, causing the movable seats 216 at both ends to move away from or close to each other, thereby moving the corresponding auxiliary frames 53, facilitating the active opening or close clamping of the two groups of auxiliary frames 53 at the first support seat 51.

[0040] Further, an inclined slot 132 is provided inside the limiting piece 131. The ejecting mechanism includes a linear driver 133. The output end of the linear driver 133 is fixedly provided with an ejecting rod 134, and the ejecting rod 134 slides along the inside of the inclined slot 132. A temperature detection module 14 and a leakage detection module 15 are installed at the bottom of the housing 11, and the temperature detection module 14 is located on one side of the leakage detection module 15. The detection directions of both the temperature detection module 14 and the leakage detection module 15 are vertically downward. A vision detection module 7 is installed on the guiding mechanism 2.

[0041] It should be noted that the inclination direction of the inclined slot 132 refers to the appendix Figure 3, when the linear driver 133 drives the ejector rod 134 to extend, the ejector rod 134 slides along the inclined groove 132, causing the limit piece 131 to gradually extend from inside the connection box 13 until it limits the extension piece 33. The temperature detection module 14 uses infrared temperature measurement technology to detect the surface temperature distribution of the cable 4. Local overheating indicates leakage or poor contact at that part. The leakage detection module 15 uses electromagnetic detection technology to locate the current leakage point caused by insulation damage of the cable 4 by measuring the magnetic field distribution around the cable 4. The visual detection module 7 is a high-definition camera used to identify sheath damage, mechanical damage or foreign object entanglement of the cable 4. After detecting power leakage at a certain part of the cable 4, an emergency plan is activated, such as local repair or replacement of the entire section.

[0042] Furthermore, steering vanes 16 are rotatably installed on both sides of the housing 11, and a drive tail seat 17 is installed at one end of the housing 11 away from the headstock 12.

[0043] It should be noted that the steering vane 16 is a prior art and is driven by a motor. When the steering vane 16 rotates to change the angle, the traveling route of the inspection mechanism 1 can be changed according to the rotation angle of the steering vane 16. The drive tail seat 17 is an impeller assembly of the prior art, providing power for the traveling of the inspection mechanism 1.

[0044] Furthermore, the cable 4 includes a protruding section and a recessed section. Both the protruding section and the recessed section include a middle straight section. Vertical sections one and two are respectively connected to both ends of the middle straight section. The end of the vertical section one away from the middle straight section is connected to the rear straight section, and the end of the vertical section two away from the middle straight section is connected to the front straight section. The guiding mechanism 2 moves successively along the directions of the rear straight section, the vertical section one, the middle straight section, the vertical section two, and the front straight section.

[0045] It should be noted that the inclination angles of the vertical section one and the vertical section two are detected in advance by the visual detection module 7 on the guiding mechanism 2. When the inclination angles of the vertical section one and the vertical section two are relatively large, being in the range of 60 - 90 degrees, the two sets of auxiliary frames 53 at the first support seat 51 are actively opened, and the single-wheel group of the second support seat 55 is used to guide and cross the arc point. At the vertical section one, the middle straight section, and the vertical section two, the two sets of auxiliary frames 53 at the first support seat 51 are approached and clamped again to prevent the guiding mechanism 2 from getting stuck at the arc point. When the inclination angles of the vertical section one and the vertical section two are relatively large, being in the range of 30 - 60 degrees, since the angle of the arc point is relatively small, it is not necessary to actively open the two sets of auxiliary frames 53 at the first support seat 51.

[0046] Furthermore, an installation chamber one 21 is installed on the bottom plate 23. One end of the installation chamber one 21 is provided with an installation chamber two 22. The driver two 212 is located inside the installation chamber one 21, and the installation chamber two 22 is a waterproof and enclosed box member.

[0047] It should be noted that the installation chamber two 22 is a waterproof member, and the inside is used to install control devices and power supplies.

[0048] When the cable 4 is jammed due to the filling of underwater debris between the main clamping wheel 52 and the auxiliary clamping wheel 54, the power applied by the inspection mechanism 1 to the auxiliary frame 53 is insufficient to drive the guiding mechanism 2 to continue moving forward, resulting in the guiding mechanism 2 being stuck on the cable 4 and difficult to remove, and unable to provide a guiding effect.

[0049] Refer to the attached instruction manual Figures 7 to 11 To solve this problem, the following technical solutions are also provided: A power assisting mechanism 6 is provided at the bottom of the bottom plate 23, and the power assisting mechanism 6 is located between the first support seat 51 and the second support seat 55. The power assisting mechanism 6 includes an output shaft 61. One end of the output shaft 61 is provided with an auxiliary wheel 62. A first driver 211 is installed inside the first installation chamber 21, and the output end of the first driver 211 is fixedly connected to the output shaft 61.

[0050] It should be noted that the surface of the auxiliary wheel 62 is a rough surface, and the first driver 211 and the second driver 212 adopt a separate waterproof design. The specific waterproof design refers to the existing mature technology.

[0051] Furthermore, a cleaning component 56 is installed on the auxiliary frame 53. The cleaning component 56 includes a wheel frame and a cleaning wheel. The cleaning wheel is rotatably installed on the wheel frame. The wheel frame is detachably connected to the auxiliary frame 53 by bolts, and the inclination angle of the wheel frame is set between 45 - 90 degrees.

[0052] It should be noted that the cleaning wheel of the cleaning component 56 rotates passively and adopts a rolling cleaning method to clean the top surface of the cable 4 between the main clamping wheel 52 and the auxiliary clamping wheel 54.

[0053] In this embodiment, the implementation scenario is specifically as follows: The first driver 211 drives the auxiliary wheel 62 to roll on the side of the cable 4 through the output shaft 61, playing a role of auxiliary power, increasing the traveling power when the guiding mechanism 2 is stuck, and at the same time enabling the guiding mechanism 2 to serve as a traction mechanism to drive the inspection mechanism 1 to travel, ensuring the smooth progress of the detection work, and cleaning along the top surface of the cable 4 through the cleaning component 56.

[0054] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
