Description

TECHNICAL FIELD

[0001] The present application relates to the field of power system monitoring, in particular to an intelligent monitoring device for power system. BACKGROUND

[0002] The power system is a unified whole composed of power generation, power supply (power transmission, power transformation, power distribution), power utilization facilities, and secondary facilities required for normal operation, such as regulation and control, relay protection and safety automation, metering, dispatching automation, and power communication. In cities, in order to protect cable lines and ensure the safety and reliability of cables, cable trenches are usually dug on the ground for cable laying. A large number of cable lines are laid in existing cable trenches. In order to avoid overheat of cable lines in the cable trench due to damage, causing the cable in the cable trench to catch fire, a patrol robot is often used in the cable trench to patrol and avoid overheat of the cable line, which may cause the cable line to burn and affect normal power supply.

[0003] A cable trench patrol robot is disclosed in a patent with publication number CN111633662B and publication date October 15, 2024. The cable trench patrol robot includes a base expansion system and a camera lifting system arranged on the base expansion system. The base expansion system includes a base plate, a linear motion unit, a cantilever plate, a walking assembly, and a jacking assembly. The camera lifting system includes a travel block, a four-bar linkage assembly, a support rod, and a camera assembly. The patent achieves wall penetration operation through the cable trench, thereby avoiding many use problems caused by the existence of a firewall, and efficiently completing the scheduled patrol task.

[0004] In existing cable trenches, in order to lay more cables, multiple cable brackets are usually arranged in multiple layers at intervals, and multiple cables are laid side by side on one cable bracket. When the patrol robot monitors the temperature of the cables on the multiple cable brackets, in order to adapt to cable brackets at different heights, the height of the infrared thermal imager can be adjusted. However, there are multiple cables on each cable bracket. When the infrared thermal imager monitors the temperature, it can only monitor a few cables away from the wall surface on the cable bracket, and the cables close to the wall surface on the cable bracket are not easily captured by the infrared thermal imager, resulting in a monitoring blind area. When the temperature of the cables close to the wall surface is too high, the infrared thermal imager cannot capture all the cables when the patrol robot patrols. SUMMARY

Detailed Implementation

[0031] In order for those skilled in the art to better understand the technical solutions of the present application, the following will combine the accompanying drawings to further describe the present application in detail. Figures 1-10 The present application will be further described in detail.

[0032] In the embodiments of the present application, for the convenience of description and understanding, the extension direction of the cable trench is referred to as the length direction, the direction perpendicular to the length direction on the horizontal plane is referred to as the width direction, and the direction of gravity is referred to as the vertical direction, that is, the length direction, the width direction and the vertical direction constitute a three-dimensional orthogonal coordinate system.

[0033] The present application provides an intelligent monitoring device for a power system, comprising a mobile base 1, a telescopic mechanism 2 and an infrared thermal imaging mechanism 3, the telescopic mechanism 2 is arranged on the mobile base 1, further comprising a deployment mechanism 4 arranged on the telescopic mechanism 2, the infrared thermal imaging mechanism 3 is installed on the deployment mechanism 4, when the telescopic mechanism 2 is elongated along the vertical direction, the deployment mechanism 4 is deployed towards both sides of the mobile base 1, and the infrared thermal imaging mechanism 3 is extended into the upper side of the cable for thermal imaging detection.

[0034] Specifically, the mobile base 1 can be a mobile trolley, which can move in the cable trench (or underground pipe gallery, hereinafter for the convenience of description, only the cable trench is described) according to the set track, or can be controlled to move by remote control means, the automatic walking trolley is a prior art, and its principle will not be described again. The mobile base 1 moves along the cable trench to patrol the cables laid in the cable trench. The telescopic mechanism 2 can be a hydraulic telescopic rod, an electric control telescopic rod or other telescopic structure. The deployment mechanism 4 is connected to the telescopic mechanism 2, and the infrared thermal imaging mechanism 3 for monitoring the temperature of the cable is installed on the deployment mechanism 4. The infrared thermal imaging mechanism 3 can be a common infrared thermal imager. Obviously, other types of cable detection sensors can also be arranged on the deployment mechanism 4. In this embodiment, the telescopic mechanism 2 is arranged along the vertical direction. With the telescopic mechanism 2, the infrared thermal imager moves in the vertical direction, which is convenient for monitoring cables at different heights. The existing cable trench is opened below the ground, and a plurality of cable brackets are arranged on the two side walls of the cable trench along the vertical direction. A plurality of cables are laid on each cable bracket, and the plurality of cables are arranged in parallel along the width direction. When the cables in the cable trench need to be patrolled, the mobile base 1 moves along the cable trench, and at the same time, the telescopic mechanism 2 is telescoped, and the infrared thermal imaging mechanism 3 moves up and down to adjust the position of the infrared thermal imaging mechanism 3 to adapt to the thermal imaging detection of the cables on the cable brackets at different heights.

[0035] Obviously, since multiple parallel cables are laid on each cable tray along the width direction, when the infrared thermal imaging mechanism 3 is monitoring, the cables close to the side wall of the cable trench are easily blocked by the cables far away from the side wall of the cable trench and the cable tray above, and the infrared thermal imaging mechanism 3 cannot shoot the blocked cables when performing thermal imaging detection. At this time, the infrared thermal imaging mechanism 3 has a detection blind area. As the mobile base 1 passes, if the temperature of the blocked cable is too high, the infrared thermal imaging mechanism 3 cannot shoot the temperature abnormal cable, and the temperature abnormal cable continues to work, which is easy to cause a spontaneous combustion accident and has certain safety hazards.

[0036] In order to solve the above problems, the telescopic mechanism 2 is also provided with a deployment mechanism 4, and the infrared thermal imaging mechanism 3 is installed on the deployment mechanism 4. When the telescopic mechanism 2 is elongated along the vertical direction, the deployment mechanism 4 is deployed towards both sides of the mobile base 1, and the infrared thermal imaging mechanism 3 is inserted above the cable for thermal imaging detection.

[0037] Specifically, the deployment mechanism 4 can be selected from linear telescopic rods, electric telescopic rods and other telescopic structures. The infrared thermal imaging mechanism 3 is installed on the telescopic end (the end away from the telescopic mechanism 2) of the deployment mechanism 4. After the telescopic mechanism 2 is elongated in the vertical direction, the deployment mechanism 4 starts to deploy. The deployment mechanism 4 carries the infrared thermal imaging mechanism 3 in the interval between the cable trays. At this time, the infrared thermal imaging mechanism 3 performs thermal imaging detection on the cables on the cable trays below. As the deployment mechanism 4 is elongated, the infrared thermal imaging mechanism 3 moves along the width direction, and can perform thermal imaging detection on all the cables laid on the cable trays, avoiding the occurrence of missed shooting, and causing the cables in the cable trench to have a spontaneous combustion accident due to high temperature.

[0038] Preferably, the telescopic mechanism 2 comprises an outer cylinder 21, an electric control telescopic unit 22 and a plurality of inner cylinders 23, the outer cylinder 21 and the plurality of inner cylinders 23 are both rectangular frame shapes, the outer cylinder 21 and the plurality of inner cylinders 23 are concentrically arranged and connected with each other in sliding mode, thereby forming a telescopic structure of being successively sleeved, the electric control telescopic unit 22 is installed on the inner bottom surface of the outer cylinder 21, the telescopic end of the electric control telescopic unit 22 is connected with the innermost inner cylinder 23, so that the telescoping of the electric control telescopic unit 22 can drive the innermost inner cylinder 23 to rise and in turn drive the plurality of inner cylinders 23 to telescope on the outer cylinder 21; the two side walls of the inner cylinder 23 which are symmetrical along the width direction are both provided with an adjusting sliding groove 231, the adjusting sliding groove 231 is vertically arranged, and a position adjusting mechanism is further arranged in the adjusting sliding groove 231, the position adjusting mechanism is used for adjusting the position of the unfolding mechanism 4 in the adjusting sliding groove 231; the unfolding mechanism 4 comprises a sliding seat 41 and an unfolding rod 42, the sliding seat 41 is slidably installed in the adjusting sliding groove 231, the sliding seat 41 is in U shape, the bottom surface of the sliding seat 41 is connected with the position adjusting mechanism, a connecting rod 61 is fixedly installed in the U-shaped gap of the sliding seat 41, the connecting rod 61 penetrates the unfolding rod 42 in radial direction, the unfolding rod 42 is rotatably connected with the connecting rod 61 through a torsional spring 43, the infrared thermal imaging mechanism 3 is installed at the end of the unfolding rod 42 away from the sliding seat 41, and the unfolding rod 42 is in telescopic rod shape.

[0039] Specifically, in the embodiment, the number of inner tubes 23 is set to three, it should be noted that the number of inner tubes 23 is not constant three, the number of inner tubes 23 is based on the number of vertical cable brackets; wherein the position adjusting mechanism comprises a first electric telescopic rod and a positioning lens, the first electric telescopic rod is fixedly installed in the adjusting sliding groove 231, the first electric telescopic rod is arranged in the vertical direction, the telescopic end of the first electric telescopic rod is connected with the bottom surface of the sliding seat 41, the positioning lens is also installed on the telescopic end of the first electric telescopic rod, the shooting direction of the positioning lens is opposite to the side wall of the cable trench, the positioning lens is used for positioning the gap position between the two adjacent cable brackets in the vertical direction, when the telescopic mechanism 2 is completely unfolded in the vertical direction, the torsional spring 43 releases the accumulated elastic potential energy, the unfolding rod 42 rotates on the sliding seat 41, the unfolding rod 42 changes from the vertical placement state to the horizontal placement state, then the first electric telescopic rod starts to lengthen, pushes the sliding seat 41 and the unfolding rod 42 to slide along the groove of the adjusting sliding groove 231, at the same time, the positioning lens shoots the side wall of the cable trench, when the positioning lens is positioned to the space between the two adjacent cable brackets in the vertical direction, the first electric telescopic rod stops lengthening, at this time, the unfolding rod 42 is opposite to the space between the two adjacent cable brackets, which is convenient for subsequent infrared temperature measurement detection; when the telescopic mechanism 2 is in the contracted state, the plurality of inner tubes 23 are accommodated in the outer tube 21, at this time, the unfolding rod 42 is accommodated in the adjusting sliding groove 231 on the side wall of the inner tube 23, the sliding seat 41 is located at the lower end of the adjusting sliding groove 231, at this time, the torsional spring 43 connected with the unfolding rod 42 on the sliding seat 41 is in the deformed state, and the torsional spring 43 accumulates elastic potential energy; the unfolding rod 42 can be selected as a second electric telescopic rod;

[0040] When the mobile base 1 enters into the cable trench, the electric control telescopic unit 22 drives the plurality of inner barrels 23 to extend along the vertical direction, when the plurality of inner barrels 23 are completely unfolded, the adjusting sliding grooves 231 on the side walls of the plurality of inner barrels 23 are exposed, the unfolding rods 42 in the adjusting sliding grooves 231 lose the restriction of the rest of the outer barrels 23 or the outer barrel 21 on the outside, the torsional springs 43 connected with the unfolding rods 42 release the accumulated elastic potential energy, the unfolding rods 42 rotate on the sliding seats 41, and the ends of the unfolding rods 42 away from the sliding seats 41 are deflected towards the side wall of the cable trench. When the torsional springs 43 completely release the accumulated elastic potential energy, the unfolding rods 42 are in a horizontal placement state. Subsequently, the first electric control telescopic rod extends upwards, and the first electric control telescopic rod moves the sliding seat 41 upwards along the adjusting sliding groove 231. While the sliding seat 41 moves, the positioning lens synchronously photographs the side wall of the cable trench. When the positioning lens is positioned at the gap position between the adjacent two cable brackets in the vertical direction, the first electric control telescopic rod stops extending. At this time, the unfolding rod 42 extends, and the infrared thermal imaging mechanism 3 moves towards the side wall of the cable trench. The infrared thermal imaging mechanism 3 enters the space between the adjacent two cable brackets in the vertical direction and performs thermal imaging detection on the cables in the space, so as to avoid the occurrence of missed shooting and the occurrence of self-ignition of the cables in the cable trench due to high temperature. When the photographing process of the cable trench is completed, the unfolding rod 42 is retracted to the shortest state. Subsequently, the first electric control telescopic rod moves the sliding seat 41 to the lowermost end of the adjusting sliding groove 231. Finally, the electric control telescopic unit 22 retracts the plurality of inner barrels 23 into the outer barrel 21. With the retraction of the inner barrel 23, the unfolding rod 42 on the side wall of the inner barrel 23 is extruded by the end of the outer barrel 21 or the inner barrel 23 below, the unfolding rod 42 rotates on the sliding seat 41 and is stored in the adjusting sliding groove 231, and the storage of the unfolding mechanism 4 is completed. When the telescopic mechanism 2 completes the extension operation, the center of gravity of the mobile base 1 is offset upwards. In order to ensure the stability of the mobile base 1 in the subsequent driving process, a receiving groove is also formed on the surface of the mobile base 1. A connecting rod supporting mechanism is arranged in the receiving groove. The connecting rod supporting mechanism, the outer barrel 21 and the mobile base 1 form a triangular structure, which improves the stability of the trolley in the driving process. The prior art is not described in detail.

[0041] Obviously, in the retracted state, the infrared emission end of the infrared thermal imaging mechanism 3 and other sensors are opposite to the inner wall of the inner barrel 23 or the outer barrel 21. When the infrared thermal imaging mechanism 3 is repeatedly stored and unfolded, the infrared emission end of the infrared thermal imaging mechanism 3 repeatedly rubs against the inner wall of the outer barrel 21 or the inner barrel 23, which easily causes scratches or wear on the surface of the infrared thermal imaging optical element, thereby affecting the transmission of any infrared radiation through them, ultimately causing image blur or temperature measurement distortion, and affecting the accuracy of the monitoring result.

[0042] To solve the problem, in another embodiment of the present application, a protection groove 232 is further arranged in the adjusting groove 231 and used for accommodating the infrared thermal imaging mechanism 3; the unfolding rod 42 is hollow, and includes an invariable section 421 rotationally connected with the sliding seat 41 and a telescopic adjusting section, and the infrared thermal imaging mechanism 3 is rotationally arranged at the end of the adjusting section away from the invariable section 421, wherein the sliding seat 41 is further provided with an adjusting mechanism 6, when the unfolding rod 42 rotates on the sliding seat 41, the adjusting mechanism 6 adjusts the shooting direction of the infrared thermal imaging mechanism 3, so that the infrared thermal imaging mechanism 3 is directed to the cable below; the connecting rod 61 penetrates the invariable section 421 of the unfolding rod 42 radially, and the adjusting mechanism 6 includes a first helical gear 62 arranged on the connecting rod 61, the first helical gear 62 is coaxially arranged with the connecting rod 61, the first helical gear 62 is located in the interior of the unfolding rod 42, a second helical gear 63 matched with the first helical gear 62 is arranged outside the first helical gear 62, the second helical gear 63 is rotationally arranged on the inner wall of the invariable section 421 through a connecting piece, and a passive telescopic rod 64 is arranged at the end of the second helical gear 63 away from the sliding seat 41, and the passive telescopic rod 64 is connected with the infrared thermal imaging mechanism 3.

[0043] Specifically, in the initial state, the expansion rod 42 is accommodated in the adjusting slot 231, and the infrared thermal imaging mechanism 3 is located in the protection slot 232, that is, the infrared thermal imaging mechanism 3 is located on the side of the expansion rod 42 close to the inner cylinder 23. After the cable inspection in the cable trench is completed, the inner wall of the inner cylinder 23 and the outer cylinder 21 cannot contact the infrared emission end of the infrared thermal imaging mechanism 3 when the expansion mechanism 4 is accommodated, thereby avoiding the surface of the infrared thermal imaging optical element from being scratched or worn, and ensuring the accuracy of the monitoring data. When the mobile base 1 needs to be inspected in the cable trench, the electric control telescopic unit 22 drives the plurality of inner cylinders 23 to extend in the vertical direction. When the plurality of inner cylinders 23 are completely expanded, the adjusting slots 231 on the side walls of the plurality of inner cylinders 23 are exposed, and the expansion rod 42 in the adjusting slot 231 loses the restriction of the rest of the inner cylinders 23 or the outer cylinder 21 on the outside. The torsional spring 43 connected to the expansion rod 42 releases the accumulated elastic potential energy, the expansion rod 42 rotates on the sliding seat 41, and the end of the expansion rod 42 away from the sliding seat 41 deflects toward the side wall of the cable trench. The second bevel gear 63 on the inner wall of the invariable section 421 engages with the first bevel gear 62, and the second bevel gear 63 rotates. With the rotation of the second bevel gear 63, under the action of the passive telescopic rod 64, the second bevel gear 63 rotates with the infrared thermal imaging mechanism 3 at the end of the adjusting section away from the invariable section 421. When the torsional spring 43 completely releases the accumulated elastic potential energy, the expansion rod 42 is in a horizontal placement state. At this time, the shooting direction of the infrared thermal imaging mechanism 3 is downwardly arranged (obviously, in this embodiment, the expansion rod 42 rotates by ninety degrees on the sliding seat 41, and the infrared thermal imaging mechanism 3 rotates by one hundred and eighty degrees on the adjusting section of the expansion rod 42, so that the transmission ratio of the first bevel gear 62 and the second bevel gear 63 is one to two. However, the transmission ratio of the first bevel gear 62 and the second bevel gear 63 is not constant at one to two. The transmission ratio of the first bevel gear 62 and the second bevel gear 63 is selected based on the actual situation), and then the first electric control telescopic rod extends upwardly, and the first electric control telescopic rod moves the sliding seat 41 upwardly along the adjusting slot 231. While the sliding seat 41 moves, the positioning lens synchronously shoots the side wall of the cable trench. When the positioning lens is positioned at the gap position between the two adjacent cable brackets in the vertical direction, the first electric control telescopic rod stops extending. At this time, the expansion rod 42 extends, and the infrared thermal imaging mechanism 3 moves toward the side wall of the cable trench. The infrared thermal imaging mechanism 3 enters the space between the two adjacent cable brackets in the vertical direction and performs thermal imaging detection on the cable in the space, thereby avoiding the missed shooting and causing the cable in the cable trench to self-ignite due to the high temperature.

[0044] Obviously, in the embodiment, when the torsion spring 43 releases the accumulated elastic potential, the unfolding rod 42 starts to rotate, and at the same time, the second bevel gear 63 on the unfolding rod 42 will mesh with the first bevel gear 62 due to the rotation of the unfolding rod 42, thereby synchronously rotating with the infrared thermal imaging mechanism 3, that is, when the infrared thermal imaging mechanism 3 has not yet left the protection groove 232, the infrared thermal imaging mechanism 3 has already started to deflect, and interference may occur,

[0045] To solve the above problems, preferably, the connecting rod 61 comprises two connecting sections 611 on both sides and a moving section 612 in the middle, the two connecting sections 611 are respectively connected with the two side plates of the gap of the sliding seat 41, the moving section 612 is in sliding connection with the two connecting sections 611, the end faces of the two connecting sections 611 close to the moving section 612 are provided with moving sliding grooves 613 in the vertical direction, the two ends of the moving section 612 are provided with moving sliding blocks 614, the moving sliding blocks 614 at the two ends of the moving section 612 are respectively inserted into the moving sliding grooves 613 of the two connecting sections 611, the first bevel gear 62 is installed on the moving section 612, and the sliding seat 41 is further provided with a tensioning mechanism 7, the tensioning mechanism 7 is used for adjusting the sliding of the moving section 612 along the moving sliding grooves 613, and adjusting the mutual separation or meshing of the first bevel gear 62 and the second bevel gear 63; the tensioning mechanism 7 comprises an adjusting frame 71, the adjusting frame 71 is connected with the bottom of the sliding seat 41 through a frame body, the adjusting frame 71 is provided with a vertical sink groove 72, a vertical adjusting sleeve 73 is slidingly installed in the sink groove 72, the adjusting sleeve 73 is connected with the adjusting frame 71 through an adjusting spring 75, the adjusting sleeve 73 is fixedly connected with the moving section 612 of the connecting rod 61, a vertical adjusting rod 74 is slidingly installed on the adjusting frame 71, one end of the adjusting rod 74 abuts against the bottom surface of the adjusting sleeve 73, and the other end of the adjusting rod 74 penetrates through the adjusting frame 71; a trigger strip 8 is installed on the inner wall of the invariable section 421; the trigger strip 8 comprises an adjusting section 81 and a maintaining section 82, the adjusting section 81 and the maintaining section 82 are both in the shape of an arc strip, the adjusting section 81 and the maintaining section 82 are eccentrically arranged, the arc center of the maintaining section 82 coincides with the axis of the connecting section 611, and the arc center of the adjusting section 81 is located below the axis of the connecting section 611.

[0046] Specifically, in the initial state, the moving section 612 of the connecting rod 61 is located below the two connecting sections 611, at this time, the first bevel gear 62 and the second bevel gear 63 on the moving section 612 are in a state of mutual separation. When the mobile base 1 needs to perform inspection in the cable trench, the electric control telescopic unit 22 drives the plurality of inner cylinders 23 to extend in the vertical direction. When the plurality of inner cylinders 23 are completely unfolded, the adjusting sliding groove 231 on the side wall of the plurality of inner cylinders 23 is exposed, the unfolding rod 42 in the adjusting sliding groove 231 loses the restriction of the rest of the outer cylinders 23 or the outer cylinder 21, the torsion spring 43 connected to the unfolding rod 42 releases the accumulated elastic potential energy, the unfolding rod 42 rotates on the sliding seat 41, and the end of the unfolding rod 42 away from the sliding seat 41 deflects towards the side wall of the cable trench. At this time, because the first bevel gear 62 and the second bevel gear 63 are in a state of mutual separation, with the rotation of the unfolding rod 42, the second bevel gear 63 does not mesh with the first bevel gear 62, so that the second bevel gear 63 does not rotate. At this time, the infrared thermal imaging mechanism 3 still maintains the initial state, and with the rotation of the unfolding rod 42, the trigger bar 8 on the unfolding rod 42 rotates synchronously. The adjusting section 81 of the trigger bar 8 first contacts the adjusting rod 74. Because the adjusting section 81 is eccentrically arranged, with the continuous rotation of the unfolding rod 42, the adjusting section 81 presses the adjusting rod 74 upwards, and the adjusting rod 74 moves towards the inside of the adjusting frame 71 under the pressing of the adjusting section 81. The adjusting rod 74 pushes the adjusting sleeve 73 to move upwards, and the adjusting sleeve 73 moves upwards with the moving section 612 and the first bevel gear 62. When the infrared thermal imaging mechanism 3 is separated from the adjusting sliding groove 231, the first bevel gear 62 meshes with the second bevel gear 63, the maintaining section 82 of the trigger bar 8 abuts against the adjusting rod 74, because the center of the arc of the maintaining section 82 coincides with the axis of the connecting section 611, so that with the rotation of the unfolding rod 42, the adjusting rod 74 will not continue to push the adjusting sleeve 73 to move upwards. Furthermore, because the first bevel gear 62 and the second bevel gear 63 are in a meshing state, with the rotation of the unfolding rod 42, the second bevel gear 63 meshes with the first bevel gear 62, and the second bevel gear 63 rotates. With the rotation of the second bevel gear 63, the second bevel gear 63 rotates with the infrared thermal imaging mechanism 3 at the end of the adjusting section away from the invariant section 421 under the action of the passive telescopic rod 64, until the shooting direction of the infrared thermal imaging mechanism 3 is arranged downward, so that only one protective groove 232 matched with the infrared thermal imaging mechanism 3 needs to be opened.

[0047] It should be further explained that, in a preferred embodiment, in order to improve the passability of the mobile base 1 in the cable trench, the height of the mobile base 1 should be low, and therefore the mobile base 1 is further provided with a deflection motor 5, the output shaft of the deflection motor 5 being connected with the side wall of the outer cylinder 21, and in the initial state, the outer cylinder 21 is horizontally placed on the mobile base 1, when the thermal imaging monitoring is needed, the deflection motor 5 rotates with the outer cylinder 21, so that the outer cylinder 21 changes from the horizontal placement state to the vertical state.

[0048] The foregoing merely illustrates some exemplary embodiments of the present application, no doubt numerous modifications can be made by those skilled in the art without departing from the spirit and scope of the present application. Therefore, the above description and the accompanying drawings should not be considered limiting, the scope of the present application should be defined by the appended claims.
