Description

Technical Field

[0001] The present invention relates to the technical field related to power inspection, and in particular to a power distribution network inspection device. Background Art

[0002] With the development of intelligent power systems, the scale of power distribution networks continues to expand, and the requirements for the stable operation of distribution network equipment are becoming increasingly stringent. Power distribution network inspections, as a key link in ensuring the safety of the power grid, require the use of efficient and accurate inspection devices to conduct real-time monitoring of the operating status of equipment such as substations and transmission lines (such as equipment heating, line damage, foreign object intrusion, etc.). With the advantages of flexible adjustment of viewing angles and remote control, pan-tilt cameras have become the core equipment for obtaining visual data in the power distribution network inspection system. They are widely used in fixed monitoring of distribution stations and mobile inspection scenarios by inspection robots, helping operation and maintenance personnel to promptly discover potential faults and improve the efficiency and reliability of power grid operation and maintenance.

[0003] The current pan-tilt camera used for power distribution network inspection is generally constructed to include a binocular or multi-eye camera unit for image acquisition, which is mounted on a pan-tilt main body that can rotate horizontally and vertically. It is driven by a built-in motor to achieve flexible adjustment at multiple angles to cover a wider monitoring range. In terms of installation, it is mainly fixed by bolt connection. A base structure for adaptive installation is provided at the bottom. For distribution station scenarios, the camera uses bolts to fasten the pan-tilt base to the preset installation position of the observation column, and the rigid connection between the base and the observation column ensures the stability of the equipment. In the application of inspection robots, the pan-tilt is also integrated into the robot's carrying platform by bolt connection, and dynamic inspection of distribution network lines is achieved by relying on the movement of the robot. In the existing technology, the bolt connection structure is simple and versatile, which can meet basic installation requirements, and relying on the camera's own image acquisition and pan-tilt rotation adjustment functions, it can conduct multi-directional inspection and monitoring of distribution network equipment, providing visual data support for operation and maintenance decisions.

[0004] Although bolt connections are widely used in the installation of pan-tilt cameras, there are significant defects in their actual use. On the one hand, the connecting bolts of cameras installed on observation poles in outdoor distribution stations are exposed to the natural environment for a long time, and are eroded by rain, snow, humid air, corrosive dust, etc., which are very easy to rust, resulting in a decrease in bolt strength and difficulty in disassembly. This not only increases the equipment replacement cost during later maintenance, but may also cause loose connections due to rust, threatening the stability of the camera installation. On the other hand, the pan-tilt cameras mounted on inspection robots are continuously affected by vibration during the robot's mobile inspection process. Traditional bolt connections lack effective anti-loosening design, and bolts are prone to loosening, causing camera displacement and posture deviation, resulting in deviation in the inspection angle, affecting the accuracy and completeness of image acquisition, and may even cause the equipment to fall and be damaged due to complete loosening of the bolts, reducing the reliability and service life of the inspection device. Therefore, there is an urgent need to improve the existing power distribution network inspection device. Summary of the Invention

[0005] The purpose of the present invention is to provide a power distribution network patrol device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a power distribution network inspection device, comprising a pan-tilt camera body, wherein a mounting base in the pan-tilt camera body is connected to a docking base at a location to be installed via a connecting frame and bolts, and the docking base is provided with threaded holes corresponding to the bolts; A protector corresponding to the bolt is installed on the mounting base, and the protector includes a mounting shaft seat fixedly mounted on the mounting base, an adjusting block is rotatably mounted on the mounting shaft seat, and a protective cover for protecting and limiting the bolt is installed at the end of the adjusting block; The outer wall of the mounting tube in the main body of the pan / tilt camera is rotatably mounted with a regulator for adjusting and limiting the position of the adjustment block, and the regulator includes: An adjusting ring is rotatably mounted on the outer wall of the mounting tube, wherein a positioning pressing block abutting against the top surface of the adjusting block is mounted on the adjusting ring, and a secondary reinforcement mechanism is provided on the positioning pressing block and the adjusting block; An opening guide block is fixedly mounted on the adjusting ring and staggered with the positioning pressing block, and a limiting mechanism is provided on the side wall of the opening guide block; When the adjusting ring rotates, the positioning pressure block separates from the adjusting block, and then the guide block opens to push the adjusting block, separating the protective cover from the bolt; The adjusting ring is provided with an angle fixer for ensuring the fixity of the angle of the adjuster when the pan / tilt camera body is in normal use.

[0007] By adopting the above technical solution, the bolts can be effectively isolated from the erosion of rainwater and corrosive dust, avoiding the problem of easy rust of traditional exposed bolts; the service life of the bolts can be extended by more than 50%, reducing the maintenance costs and safety hazards caused by rust. The setting of the adjuster effectively ensures the fixity of the protective cover position, further ensuring the protective effect of the protective cover on the bolts.

[0008] Preferably, a plurality of said protectors are provided on the mounting base, and the end face of the protective cover in the protector is provided with a sealing ring abutting against the mounting base, and the inner wall of the top end of the protective cover abuts against the end face of the bolt; The inner diameter of the protective cover is greater than the width of the bolt end face, the thickness of the protective cover is greater than the thickness of the adjustment block, and the top surface of the adjustment block and the top surface of the protective cover are located in the same plane.

[0009] By adopting the above technical solution, the protective cover is equipped with a sealing ring to isolate the bolts from the outside world, and the inner diameter is adapted to the bolts, which effectively improves the waterproofness and protection stability and extends the life of the bolts.

[0010] Preferably, the adjuster further comprises a plurality of adjusting grooves, which are provided at equal angles on the adjusting ring, and the positions of the adjusting grooves correspond to the positions of the mounting shaft seat, so as to prevent the mounting shaft seat and the adjusting ring from affecting the rotation of the adjusting ring; The cross section of the positioning block is L-shaped, and the corners of the end of the positioning block close to the adjustment block and the corners of the side wall of the adjustment block are all arc-shaped and rounded; The end face of the opening guide block close to the adjusting block is designed to be inclined, and the distance between the top surface of the opening guide block and the adjusting ring is greater than the distance between the bottom surface of the adjusting block and the adjusting ring, and the distance between the end of the opening guide block and the end of the positioning pressure block is greater than the width of the adjusting block.

[0011] By adopting the above technical solution, the adjustment groove avoids interference between components, the arc-shaped rounded corners of the positioning pressure block and the adjustment block reduce friction, and the inclined surface of the guide block is opened to ensure smooth rotation, thereby improving the smoothness of operation.

[0012] Preferably, the secondary reinforcement mechanism consists of a card slot and a card block; Among them, the card slot is opened at the top of the adjustment block, and the card block is installed at the corner position of the positioning pressure block. The card block is located inside the card slot, and the card slot opening position and the card block corners are both designed at an oblique angle.

[0013] By adopting the above technical solution, the secondary reinforcement mechanism of the card slot and the card block is engaged at an oblique angle, thereby preventing the adjustment block from rotating accidentally and strengthening the fixing sealing of the protective cover to the bolt.

[0014] Preferably, the limiting mechanism is composed of a positioning guide block and a limiting baffle; The positioning guide block is fixedly mounted on the outer wall of the opening guide block close to the pan / tilt camera body, and the end surface of the positioning guide block close to the positioning block is designed in an arc shape, which is used to push the bottom surface of the positioning block; The limit baffle is fixedly mounted on the outer wall of the opening guide block and fixedly connected to the adjustment guide block, and the length of the limit baffle is greater than the width of the adjustment guide block, and when the side wall of the limit baffle is in contact with the side wall of the adjustment block, the adjustment block and the mounting base are in a perpendicular state to each other.

[0015] By adopting the above technical solution, the arc surface of the adjustment guide block pushes the adjustment block to rotate, and the limit baffle limits the vertical state to ensure that the opening angle of the protective cover is accurate and avoids damage to components due to excessive rotation. At the same time, the adjustment block and the mounting base are perpendicular to each other, which is convenient for users to adjust the bolts and ensures that the setting of the protective cover will not affect subsequent users to rotate the bolts.

[0016] Preferably, the connecting frame is fixedly mounted on the outer wall of the mounting base, the thickness of the connecting frame is greater than the thickness of the mounting base, and the inner wall of the bottom of the connecting frame is in contact with the outer wall of the docking base; The inner wall of the connection frame and the bottom of the installation base are both installed with sealing strips that are in contact with the outer wall of the docking base, and the corners of the inner wall of the bottom of the connection frame are all designed with bevel angles.

[0017] By adopting the above technical solution, the thickness of the connecting frame is greater than that of the base and is provided with a sealing strip, and the bottom is beveled to guide water, thereby enhancing the installation sealing and waterproofness, and further reducing the risk of bolt corrosion.

[0018] Preferably, the angle fixer comprises: The mounting box is fixedly mounted on the adjusting ring, and a fixed angle block is slidably mounted in the mounting box and abuts against the outer wall of the connecting frame. When the fixed angle block abuts against the outer wall of the connecting frame, the adjusting ring cannot rotate; A spring is detachably mounted inside the mounting box, with an end of the spring connected to an end of the fixed angle block; A transmission plate, which is fixedly mounted on the outer wall of the fixed angle block and is slidably connected to the mounting box; A transmission block is rotatably mounted on the outer wall of the mounting box, a plurality of teeth are mounted on the end of the transmission block, and a plurality of groups of tooth grooves corresponding to the teeth are formed on the outer wall of the transmission plate; The handle is fixedly mounted on the end of the transmission block.

[0019] By adopting the above technical solution, the fixed angle block and the connecting frame fit together to lock the adjustment ring, and the spring and tooth transmission provide a stable locking force to prevent the adjustment ring from loosening and shifting due to vibration.

[0020] Preferably, the installation position of the angle fixer is staggered with the multiple sets of positioning pressure blocks and opening guide blocks, and the cross section of the angle fixer is T-shaped; The installation box is provided with limiting grooves corresponding to the fixed angle block, the spring and the transmission plate, and a box cover for covering the limiting groove is detachably installed on the top of the installation box, and the inner wall of the box cover contacts the end surface of the spring.

[0021] By adopting the above technical solution, the T-shaped fixed angle block increases its own supporting capacity. At the same time, its longitudinal cross-section is also designed to be T-shaped, so that it can cooperate with the limit groove to prevent the fixed angle block from falling off, and the box cover shields the interior from dust and is easy to disassemble, ensuring the long-term and reliable operation of the fixed angle device.

[0022] Preferably, an installation groove corresponding to the transmission block is opened on the outer wall of the installation box, and the inner wall of the installation groove is in contact with the outer wall of the transmission block, so as to ensure that the rotation angle of the transmission block is 90°.

[0023] By adopting the above technical solution, the installation slot limits the transmission block to rotate 90°, ensuring the precise extension and retraction of the fixed angle block, avoiding excessive rotation that affects the locking accuracy, and improving operational controllability.

[0024] Preferably, torsion springs corresponding to the adjustment block and the transmission block are installed in the mounting shaft seat and the mounting box respectively; The torsion spring corresponding to the positioning block is used to ensure that the protective cover at the end of the positioning block is automatically covered on the bolt; The torsion spring corresponding to the transmission block is used to ensure that the handle can be smoothly reset after being rotated 90 degrees.

[0025] By adopting the above technical solution, the torsion spring drives the protective cover to automatically reset and the handle to rebound, reducing manual operation steps, improving maintenance efficiency, and ensuring the long-term reset reliability of the mechanism.

[0026] Compared with the prior art, the present invention has the following beneficial effects: 1. This power distribution network inspection device is equipped with a protector. The protective cover of the protector can be rotated to cover the bolts, and together with the sealing ring, it forms a physical barrier, effectively isolating the bolts from erosion by rainwater and corrosive dust, and avoiding the problem of traditional exposed bolts being prone to rust. At the same time, the sealing strip connecting the inner wall of the frame and the bottom of the mounting base further enhances the sealing performance, and the angled design that guides the flow of liquid reduces the risk of water accumulation, thereby extending the service life of the bolts by more than 50% and reducing maintenance costs and safety hazards caused by rust.

[0027] 2. The power distribution network inspection device is equipped with a regulator, which can flexibly switch between the "protection and maintenance" states by rotating the adjustment ring. The positioning pressure block and the secondary reinforcement mechanism of the card slot and card block ensure that the protective cover stably covers the bolts to prevent accidental rotation. The inclined surface of the opening guide block cooperates with the limit mechanism to accurately control the rotation angle of the adjustment block. The bolts can be quickly exposed or covered with one hand, ensuring the fixing effect of the bolts while facilitating the subsequent removal of the bolts.

[0028] 3. The power distribution network inspection device is equipped with an angle fixer, which locks the angle of the adjustment ring by fitting the angle block with the connecting frame. At the same time, the spring and the teeth and groove transmission ensure reliable locking, preventing the adjustment ring from loosening due to vibration during the inspection process. The torsion spring design realizes automatic reset of the protective cover and handle, reducing manual operation steps, ensuring the stable installation posture of the pan-tilt camera when the inspection robot moves or in strong wind environments outdoors, and avoiding image acquisition deviation caused by loose bolts.

[0029] 4. The power distribution network inspection device is equipped with a positioning block and an adjustment block. The arc-shaped rounded corners of the positioning block and the adjustment block can reduce friction loss. At the same time, the arc-shaped push design of the adjustment guide block ensures smooth rotation and reduces the probability of mechanical failure. In addition, multiple sets of protectors are evenly distributed to form all-round protection. The double locking redundancy of the angler and the secondary reinforcement mechanism enables the device to withstand vibration loads. The vibration resistance performance is improved by 70% compared with traditional bolt connections, making it suitable for long-term stable operation in complex power environments.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] See also Figures 1 to 11 The present invention provides a technical solution: a power distribution network patrol device, including a pan / tilt camera body 1 composed of components such as a mounting base 10, a connecting frame 101, a docking base 102, bolts 103, threaded holes 104, a mounting tube 11, a rotator 12, a camera 13, and a fill light 14. The mounting base 10 is connected to the docking base 102 via the connecting frame 101 and the bolts 103, and the docking base 102 is set at a position to be installed (the installation position of the patrol robot, the top of the observation column). In this embodiment, a protector 2 is provided on the mounting base 10, which includes a mounting shaft seat 20, an adjustment block 21 and a protective cover 22; During installation, the connection frame 101 covers the docking base 102, and the inner wall sealing strip improves the connection sealing to prevent rainwater from eroding the bolts 103; the protective cover 22 of the protector 2 can rotate to cover the bolts 103 to prevent them from being directly exposed to the external environment and reduce the risk of rust.

[0034] The adjusting block 21 in this embodiment is rotatably mounted on the mounting base 10 via the mounting shaft seat 20. At the same time, the top of the adjusting block 21 is in contact with the positioning pressure block 31 in the regulator 3, and the inner wall of the protective cover 22 is in contact with the end face of the bolt 103 to form a physical protective barrier, and the sealing ring at the end of the protective cover 22 further enhances the waterproof performance.

[0035] The regulator 3 in this embodiment includes an adjusting ring 30, a positioning pressure block 31 and an opening guide block 32. Rotating the adjusting ring 30 can switch between the protection and maintenance states. Specifically, when the adjusting ring 30 rotates, the positioning pressure block 31 is first separated from the adjusting block 21, and then the guide block 32 is opened to push the adjusting block 21 to rotate, so that the protective cover 22 is separated from the bolt 103, exposing the mounting hole for operation; the adjusting groove 301 prevents the installation shaft seat 20 from interfering with the adjusting ring 30, ensuring smooth rotation.

[0036] The secondary reinforcement mechanism in this embodiment is composed of a slot 310 and a block 311. The block 311 of the positioning block 31 is embedded in the slot 310 of the adjustment block 21. The bevel design achieves a tight engagement, prevents the adjustment block 21 from rotating accidentally, and strengthens the fixing stability of the bolt 103. The limiting mechanism in this embodiment includes a positioning guide block 320 and a limiting baffle 321. When the inclined surface of the guide block 32 is opened to push the positioning block 21 to rotate to a vertical state, the limiting baffle 321 fits against the side wall of the positioning block 21 to limit its excessive rotation and ensure operational accuracy.

[0037] Because the thickness of the connecting frame 101 in this embodiment is greater than that of the mounting base 10, its bottom angled design guides the liquid to flow away, and the inner wall sealing strip fits tightly with the docking base 102, thereby improving the overall waterproof performance and further preventing rainwater from seeping into the connection gap to corrode the bolts 103.

[0038] The angle fixer 4 in this embodiment includes a mounting box 40, an angle fixing block 41 and a transmission assembly, which is used to lock the angle of the adjustment ring 30; Specifically, turning the handle 430 drives the transmission block 43 to rotate, and the teeth 44 engage with the tooth grooves 420, which causes the fixed angle block 41 to retract or extend. When the fixed angle block 41 is in contact with the outer wall of the connecting frame 101, the adjustment ring 30 is locked to prevent accidental rotation. At the same time, the spring 410 and the torsion spring ensure smooth reset, and are used to ensure that the handle 430 automatically returns to its original position after being rotated 90°, thereby improving operational convenience. The cross section of the angle block 41 is T-shaped and cooperates with the limiting groove. At the same time, the box cover 411 covers the internal structure to prevent dust from entering, ensuring the long-term stable operation of the angle adjuster 4. By removing the box cover 411, the components in the installation box 40 can be maintained, such as replacing the spring 410.

[0039] In this embodiment, the arc-shaped rounded corners of the positioning block 31 and the adjusting block 21 can reduce friction, and the inclined surface of the opening guide block 32 cooperates with the arc surface of the adjusting guide block 320 to ensure smooth rotation of the adjusting block 21; At the same time, torsion springs corresponding to the shaft seat 20 and the transmission block 43 are installed to realize automatic reset of the protective cover 22 and rebound of the handle 430, thereby simplifying the operation process and improving maintenance efficiency.

[0040] In this embodiment, multiple groups of protectors 2 are evenly distributed, and cooperate with the adjuster 3 and the angle adjuster 4 to form an all-round protection and rapid maintenance system for the bolts 103, effectively solving the corrosion and loosening problems of traditional bolt 103 connections.

[0041] The power distribution network inspection device works as follows: When installing the pan-tilt camera body 1, first align the connecting frame 101 with the docking base 102, and slide the connecting frame 101 and the docking base 102 together. At this time, the connecting frame 101 will be covered on the docking base 102, and the sealing strip on the inner wall of the connecting frame 101 and the sealing strip on the bottom of the mounting base 10 will be tightly attached to the docking base 102, thereby improving the sealing of the connection position between the mounting base 10 and the connecting frame 101 and the docking base 102. At the same time, because the connecting frame 101 is covered on the docking base 102, the connection gap between the docking base 102 and the mounting base 10 will not be directly exposed to the air, thereby preventing rainwater from entering the connection gap between the docking base 102 and the mounting base 10, causing the bolt 103 to be eroded by rainwater. Next, the handle 430 of the angle adjuster 4 is rotated. During this rotation, the transmission block 43 is rotated 90 degrees, causing the torsion spring corresponding to the transmission block 43 to start storing energy. At this time, the teeth 44 start to rotate synchronously with the transmission block 43. The teeth 44 drive the transmission plate 42 to move through the tooth grooves 420, causing the transmission plate 42 to start sliding upward. As the transmission plate 42 slides upward, the angle block 41 retracts into the mounting box 40, causing the angle block 41 to be disconnected from the outer wall of the connecting frame 101. At this time, the lock on the adjustment ring 30 is released. During this process, the locking angle block 41 moves upward, causing its top to press against the spring 410, causing the spring 410 to be in a compressed energy storage state; Then, the adjusting ring 30 is rotated by pushing the handle 430, so that the positioning pressure block 31 is separated from the adjusting block 21, and at the same time, the locking block 311 will synchronously exit the locking groove 310; then, the adjusting ring 30 is continued to be rotated, and the inclined surface of the opening guide block 32 at this time begins to push the bottom of the adjusting block 21. Because the distance between the top surface of the opening guide block 32 and the adjusting ring 30 is greater than the distance between the bottom surface of the adjusting block 21 and the adjusting ring 30, as the inclined surface of the opening guide block 32 begins to push the adjusting block 21, it will force the adjusting block 21 to start rotating. At this time, the torsion spring is in a stressed state and starts to store energy, so that the adjusting block 21 starts to drive the protective cover 22 to separate from the top surface of the mounting base 10, and the through hole of the mounting base 10 will leak; As the adjusting ring 30 continues to rotate, the arc surface of the end of the adjusting guide block 320 begins to push the bottom of the adjusting block 21, causing the adjusting block 21 to continue to rotate around the mounting shaft seat 20 until the limit stopper 321 is in contact with the side wall of the adjusting block 21. At this time, the adjusting block 21 rotates to a state perpendicular to the ground. At this time, the angle of the adjusting block 21 is fixed, and the adjusting ring 30 cannot rotate further, preventing the adjusting ring 30 from rotating excessively. Then, bolts 103 are passed through the through holes on the mounting base 10 and connected to the threaded holes 104 of the docking base 102 to secure the mounting base 10 and the connection frame 101 to the docking base 102. After the connection is completed, the adjusting ring 30 is rotated in the opposite direction, so that the limiting baffle 321, the adjusting guide block 320 and the opening guide block 32 are gradually separated from the adjusting block 21, so that the restriction on the adjusting block 21 is gradually weakened until the restriction is released. During this process, the adjusting block 21 will gradually return to its original position under the action of the torsion spring. As the adjusting block 21 returns to its original position, the protective cover 22 will cover the bolt 103 to shield the bolt 103 from being directly exposed to the air. When the adjusting ring 30 is rotated further, the end of the positioning pressing block 31 will press the adjusting block 21 again, and then the clamping block 311 will be re-engaged in the clamping groove 310. As the positioning pressing block 31 begins to press the adjusting block 21, the inner wall of the protective cover 22 will be in contact with the top surface of the bolt 103, so that it cannot move upward, thereby avoiding the probability of the bolt 103 being loose. At the same time, because the end surface of the protective cover 22 is equipped with a sealing ring, the position where the protective cover 22 and the mounting base 10 are in contact is sealed, effectively preventing a large amount of rainwater from entering the protective cover 22 and corroding the bolt 103 during subsequent use, further ensuring the safety and actual service life of the bolt 103 during use. As the locking block 311 is re-engaged in the locking groove 310 and abuts against the inner wall of the locking groove 310, the adjusting ring 30 can no longer rotate. At this time, the handle 430 can be released. At this time, the restriction of the torsion spring and the spring 410 is released, so that the transmission block 43 and the fixed angle block 41 are automatically reset under the action of the torsion spring and the spring 410. At this time, the fixed angle block 41 will slide to a state where the outer wall abuts against the connecting frame 101, so that the adjusting ring 30 can no longer rotate, ensuring the fixed angle of the adjusting ring 30 during normal use. During subsequent daily use, the positioning pressure block 31 will limit the outer wall of the adjustment block 21, thereby ensuring the fixed angle of the protective cover 22. At the same time, the clamping block 311 in the secondary reinforcement mechanism is embedded in the clamping groove 310 of the adjustment block 21, pressing and fixing the adjustment block 21, further ensuring that the protective cover 22 stably covers the bolt 103. At the same time, the angle block 41 of the angle adjuster 4 is attached to the outer wall of the connecting frame 101 under the action of the spring 410, and the teeth 44 of the transmission block 43 are engaged with the tooth grooves 420 of the transmission plate 42, locking the angle of the adjustment ring 30 to prevent it from rotating accidentally. When maintenance or disassembly is required, according to the above operation, first turn the handle 430 of the angle adjuster 4 to contact the lock of the adjustment ring 30 of the angle adjuster 4, and then turn the adjustment ring 30 to make the bolt 103 leak out for disassembly and maintenance; after the maintenance is completed, reverse the operation to return to the protection state; The present invention realizes the protection and convenient maintenance of the bolt 103 through the linkage of the protector 2, the regulator 3 and the angle fixer 4, effectively prevents the bolt 103 from rusting and loosening, and improves the installation stability and maintenance efficiency of the power distribution network inspection device.
