Description

Technical Field

[0001] This utility model belongs to the technical field of inspection vehicles, and specifically relates to a special vehicle for inspecting monitoring lines in hydropower stations. Background Technology

[0002] Hydropower stations, as core infrastructure ensuring stable energy supply and flood control safety, have inspection scopes covering key areas such as transmission line towers, dam bodies, reservoir slopes, and gate opening and closing equipment. The operating environment is characterized by complex terrain, dispersed monitoring points, and dense vertical and high-altitude distribution. To ensure the safe operation of equipment, inspection work must simultaneously monitor the condition of ground equipment and investigate potential hazards in high-altitude and facade structures.

[0003] The current hydropower station inspection model is based on "drone inspection + ground vehicle + manual assistance". Drones are used to inspect insulators of transmission lines above 3 meters, the frame structure above the dam crest, cracks and seepage points on the vertical dam surface. Ground inspection vehicles are usually equipped with fixed cameras, RTK measuring instruments and other monitoring equipment, and collect data in the horizontal direction and low areas within a height range of 1-3 meters by traveling along a preset route.

[0004] However, during the operation of the inspection vehicle, various monitoring devices need to be installed on the top of the vehicle to provide good data transmission accuracy and improve monitoring accuracy. However, the traditional monitoring devices installed on the top of the vehicle are installed at a high position, which increases the overall height of the vehicle and reduces its passability. Utility Model Content

[0005] This utility model provides a special vehicle for inspecting monitoring lines in hydropower stations, in order to solve the problem that the monitoring devices are installed at high heights and the vehicle is inconvenient to pass through height-restricted areas.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A special vehicle for inspecting monitoring lines in a hydropower station includes a vehicle body, a mounting plate fixed to the top of the vehicle body, and one or more sets of monitoring components mounted on the surface of the mounting plate. The monitoring component includes a first mounting base and a second mounting base. A movable rod is rotatably connected to the first mounting base, and the other end of the movable rod is used to mount a monitor. An electric actuator is provided between the movable rod and the second mounting base. Both ends of the electric actuator are rotatably connected. The electric actuator obliquely abuts against the side wall of the movable rod, and the telescopic electric actuator realizes the rotation and folding of the movable rod in the vertical plane. Furthermore, sliding guide rails are provided on both sides of the mounting plate, and a cover is slidably installed on the sliding guide rails. The cover is used to cover and maintain the monitoring components after they are folded up.

[0007] Furthermore, a support plate for supporting the movable rod is fixed on the side of the electric actuator away from the mounting plate, and a soft pad is fixed on the surface of the support plate.

[0008] Furthermore, a vertical limiting plate is fixed to the front end of the mounting plate, and the vertical limiting plate is used to abut against the side wall of the movable rod when the movable rod is rotated to the vertical position.

[0009] Furthermore, the movable rod has a vertically opening mounting hole, and a support frame rod is provided below the monitoring component. The support frame rod is partially inserted into the mounting hole, and a locking device for clamping and locking the support frame rod is provided at the top of the movable rod.

[0010] Furthermore, the top of the movable rod includes a first locking block, the cross-section of which is larger than the cross-section of the main body of the movable rod; The locking device includes a second locking block that fits against the first locking block, and a locking bolt threaded through the first locking block. The locking bolt is also threadedly connected to the second locking block. The support rod is clamped between the first locking block and the second locking block.

[0011] Furthermore, a drive assembly is also fixed at the rear of the mounting plate. The drive assembly includes a drive source fixed to the surface of the mounting plate and drive gears extending from both sides of the drive source. The inner walls on both sides of the canopy are fixed with racks along the length direction for meshing with the drive gear.

[0012] Furthermore, a limiting piece is fixed to the inner wall of the canopy near the vertical limiting plate, and the limiting piece is disposed in the area between the rack and the mounting plate; The mounting plate is fixed with an abutment piece near the rear of the vehicle body, and the canopy can be moved until the limiting piece abuts against the abutment piece.

[0013] Furthermore, the first mounting base includes a left limiting part and a right limiting part, the movable rod is clamped between the left limiting part and the right limiting part, and the movable rod and the first mounting base are rotatably connected by bolts.

[0014] Furthermore, the height of the vertical limiting plate is not less than the height of the covering canopy, and the width of the vertical limiting plate is not less than the width of the covering canopy. The distance between the monitoring component and the side edge of the vertical limiting plate is greater than the length of the limiting piece extending into the cover canopy.

[0015] The present invention can achieve the following beneficial effects: 1. The special vehicle of this application is equipped with a monitoring component on the top of the vehicle body. The monitoring component can collect data in areas with higher heights. The installation height of the monitor can be raised by a movable rod. The two ends of the electric push rod are respectively rotatably connected to the second mounting base and the movable rod. At the same time, the movable rod is rotatably connected to the first mounting base. Thus, the height of the monitoring component can be adjusted by the pushing and pulling force of the electric push rod to raise and lower the movable rod, thereby meeting the passage requirements of the vehicle body in height-restricted areas.

[0016] 2. A cover canopy is movably installed on the main body of the vehicle. By sliding the cover canopy, the monitoring components can be exposed or enclosed, thereby achieving protection and storage of the monitoring components under normal circumstances. At the same time, the movement of the cover canopy is driven by the drive component, and the position of the cover canopy can be locked in real time. The limit plate and the abutment plate can mechanically restrict the sliding of the cover canopy onto the main body of the vehicle.

[0017] 3. A locking device is installed at the top of the movable rod, and an installation hole is opened inside the movable rod to adjust the installation height of the monitor, thereby meeting the monitoring requirements at different heights. Attached Figure Description

Detailed Implementation

[0020] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] like Figures 1 to 4 As shown, a special vehicle for inspecting monitoring lines of a hydropower station includes a vehicle body 1, which can be a transport vehicle, serving as the basic load-bearing component; an installation plate 2 is fixedly installed on the top of the vehicle body 1, which serves as an integrated installation platform, and one or more sets of monitoring components 3 can be installed on its surface according to inspection needs to meet the monitoring needs of different areas or different types.

[0022] The monitoring component 3 includes a first mounting base 31, a second mounting base 32, a movable rod 33, and an electric actuator 35. The first mounting base 31 is fixed to the surface of the mounting plate 2. One end of the movable rod 33 is rotatably mounted on the first mounting base 31, and the other end is used to mount different types of monitors 34. The monitors 34 can be common inspection and monitoring equipment such as cameras and RTK measuring instruments to collect various data from the hydropower station lines. The second mounting base 32 is also fixed to the surface of the mounting plate 2, and the electric actuator 35 is positioned between the movable rod 33 and the second mounting base 32. Both ends of the electric actuator 35 are rotatably connected to the second mounting base 32 and the movable rod 33, respectively. The electric actuator 35 is inclined and abuts against the side wall of the movable rod 33. When the electric actuator 35 extends or retracts, it drives the movable rod 33 to rotate around the first mounting base 31, thereby achieving rotation and folding of the movable rod 33 in the vertical plane. This adjusts the height of the monitor 34, facilitating the passage of the vehicle body 1 in height-restricted areas.

[0023] In addition, a support plate 36 for supporting the movable rod 33 is fixedly installed on the side of the electric actuator 35 away from the mounting plate 2. A soft pad is also fixed on the surface of the support plate 36. When the movable rod 33 is folded, a part of the movable rod 33 will rest on the support plate 36. The soft pad can buffer the contact between the movable rod 33 and the support plate 36, and prevent the movable rod 33 from being damaged by collision.

[0024] It should be noted that the first mounting base 31 includes a left limiting part 311 and a right limiting part 312. The movable rod 33 is clamped between the left limiting part 311 and the right limiting part 312. At the same time, the movable rod 33 and the first mounting base 31 are rotatably connected by bolts, so that the movable rod 33 can rotate around the bolts in the vertical plane. The left limiting part 311 and the right limiting part 312 can more stably support the movable rod 33 and reduce the possibility of the movable rod 33 swaying left and right, providing a more stable mounting platform for the monitor 34.

[0025] A vertical limiting plate 5 is fixedly installed at the front end of the mounting plate 2. When the movable rod 33 rotates to the vertical position, the side wall of the movable rod 33 abuts against the vertical limiting plate 5, thereby limiting the rotation angle of the movable rod 33 and preventing the movable rod 33 from deviating from the preset monitoring angle due to excessive rotation. At the same time, a mounting hole is vertically opened in the movable rod 33. A support frame rod 6 is provided below the monitor 34. A section of the support frame rod 6 is inserted into the mounting hole, and a locking device 7 for clamping and locking the support frame rod 6 is provided at the top of the movable rod 33. By adjusting the insertion length of the support frame rod 6 in the mounting hole, the installation height of the monitor 34 can be further adjusted to meet the inspection needs at different heights.

[0026] Specifically, the top of the movable rod 33 includes a first locking block 331, the cross-section of which is larger than the cross-section of the main body of the movable rod 33. The locking device 7 includes a second locking block 71 that fits onto the first locking block 331, and a locking bolt 72 threaded through the first locking block 331. The locking bolt 72 is located in the area where the first locking block 331 extends beyond the cross-section of the main body of the movable rod 33, and is also threadedly connected to the second locking block 71. When the support rod 6 is inserted into the mounting hole, it will be clamped between the first locking block 331 and the second locking block 71. Tightening the locking bolt 72 will move the second locking block 71 closer to the first locking block 331, thereby firmly clamping and locking the support rod 6 and preventing it from loosening during inspection.

[0027] To protect the folded monitoring component 3, sliding guide rails 21 are provided on both sides of the mounting plate 2. A cover 4 is slidably mounted on the sliding guide rails 21 and can slide along the sliding guide rails 21 on the mounting plate 2. When the monitoring component 3 is folded, the sliding cover 4 can completely cover the monitoring component 3, achieving the purpose of covering and maintaining the monitoring component 3 and preventing dust, rainwater, etc. from corroding the monitoring component 3. At the same time, a drive component is also fixed in the area near the rear of the mounting plate 2. The drive component includes a drive source 8 fixed on the surface of the mounting plate 2 and drive gears 9 extending from both sides of the drive source 8. The drive source 8 can be a power device with forward and reverse rotation functions, such as a servo motor. Correspondingly, racks 41 for meshing with the drive gears 9 are fixedly provided on the inner walls of both sides of the cover 4 along the length direction of the cover 4. When the drive source 8 is started, it will drive the drive gears 9 on both sides to rotate. The drive gears 9 drive the cover 4 to slide along the sliding guide rail 21 through meshing with the rack 41, so as to realize the automatic opening and closing of the cover 4 without manual pushing. It can also lock the position of the cover 4 at any time to restrict the sliding of the cover 4.

[0028] In addition, a limiting piece 42 is fixedly installed on the inner wall of the canopy 4 near the vertical limiting plate 5. The limiting piece 42 is located in the area between the rack 41 and the mounting plate 2. At the same time, an abutment piece 22 is fixedly installed in the area of ​​the mounting plate 2 near the tail of the vehicle body 1. When the canopy 4 slides toward the tail of the mounting plate 2, it can move to the position where the limiting piece 42 and the abutment piece 22 abut against each other. At this time, the abutment piece 22 will block the limiting piece 42, thereby limiting the sliding stroke of the canopy 4 and preventing the canopy 4 from sliding off the sliding guide rail 21 onto the vehicle body 1.

[0029] It should be noted that the height of the vertical limiting plate 5 is not less than the height of the canopy 4, and the width of the vertical limiting plate 5 is not less than the width of the canopy 4. At the same time, the distance between the monitoring component 3 and the side edge of the vertical limiting plate 5 is greater than the length of the limiting piece 42 extending into the canopy 4. This size setting can ensure that when the canopy 4 is closed, the vertical limiting plate 5 can fit well with the end of the canopy 4, realize the all-round protection of the monitoring component 3, and avoid interference between the limiting piece 42 and the monitoring component 3, thus ensuring the stable operation of the entire structure.

[0030] During actual inspection operations, if monitoring is required, the drive source 8 can be started. The drive source 8 drives the drive gear 9 to rotate. Through the meshing of the gear and rack 41, the cover 4 slides along the sliding guide rail 21 towards the tail of the mounting plate 2 until the limit plate 42 abuts against the abutment plate 22. At this time, the cover 4 opens, exposing the monitoring component 3. Then, the electric push rod 35 is controlled to extend. The electric push rod 35 pushes the movable rod 33 to rotate around the first mounting base 31 until the movable rod 33 abuts against the vertical limit plate 5. The movable rod 33 remains vertical, and the monitor 34 is at the working height. If it is necessary to further raise the monitor 34, the locking bolt 72 can be loosened, and the extension length of the support frame rod 6 in the mounting hole can be adjusted. After the adjustment is completed, the locking bolt 72 is tightened to lock the support frame rod 6, and the height of the monitor 34 can be adjusted again. Then, the monitor 34 is started to collect inspection data.

[0031] When it is necessary to pass through the height restriction area, the electric actuator 35 is retracted. The electric actuator 35 pulls the movable rod 33 to rotate and fold around the first mounting base 31 until the movable rod 33 rests on the soft pad of the support plate 36, which can then drive the vehicle body 1 to pass through the height restriction area.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
