Description

Technical Field

[0001] The present invention relates to the technical field of identification devices, and in particular to an adjustable transmission pole license plate fixing and protection device. Background Art

[0002] Transmission line pole plates serve as the "identity cards" of transmission lines. They not only clearly display basic information such as the line name, voltage level, phase sequence, and direction, but also serve as a critical safety warning. Especially in scenarios where maintenance work is tight and safety situations are complex, the clear presentation and stable presence of pole plates can effectively serve as a warning and ensure the personal safety of maintenance personnel. Furthermore, comprehensive, unified, and realistic line markings greatly facilitate line inspections and maintenance, fundamentally reducing safety hazards caused by unclear markings and serving as a warning and guidance for passers-by to stay away from power facilities. With the continuous development of the company's power grid, the number of transmission lines has increased annually, leading to the widespread use of steel tubular towers and angle steel towers. The importance of pole number plates in the daily operation and maintenance of transmission lines has become increasingly prominent, and their use has continued to increase. However, during the long-term operation of transmission lines, pole number plates face various risks of damage and loss. Due to the complex outdoor environment, strong winds can not only cause pole number plates to fall off or be lost due to insecure mounting structures or improper installation, but can also directly damage the plates themselves, such as bending or cracking them. In some construction areas, improper construction operations can also cause collisions and scratches on the plates, causing damage. Furthermore, in dusty areas, long-term accumulation of dust can cover the plates, blurring the information on them and making them difficult to read. More importantly, once a pole number plate is damaged or lost, it often goes undetected. During construction work, operators and construction workers cannot accurately determine the true pole number, which can easily lead to serious safety accidents such as mistakenly climbing onto a live pole, posing a significant risk to construction safety. Summary of the Invention

[0012] The fixing mechanism is a clamp, which is fixedly mounted on the rear end surface of the protection box, and the protection box is fixedly connected to the transmission pole via the clamp.

[0013] The beneficial effects of the present invention are: 1. The electric hydraulic rod, rotating arm, and forward extension block of the present invention cooperate with each other and, under the control of the controller, enable flexible rotation of the license plate frame and the pole license plate. When the wind speed sensor detects strong winds, or during construction or other scenarios that could easily damage the pole license plate, the controller can control the electric hydraulic rod to move the rotating arm and retract the pole license plate into the protective box. The protective box provides reliable protection for the pole license plate, preventing deformation and dislodging caused by direct impact from strong winds, as well as damage from collisions and scrapes during construction, greatly reducing the risk of damage to the pole license plate. 2. The wind speed sensor mounted on top of the protective box monitors external wind speed in real time and transmits the data to the controller. The controller automatically determines whether to retract the pole number plate based on a preset wind speed threshold. This eliminates the need for manual intervention and allows for the timely and accurate protection of pole number plates before strong winds arrive. This intelligent protection improves the timeliness and accuracy of protection and reduces damage to pole number plates caused by untimely manual judgment. 3. The license plate frame of the present invention is formed in one piece with a left side bar, a right side bar, and a lower side bar. The upper side bar is fixed with screws, which can firmly clamp the pole license plate in the placement space and effectively prevent the pole license plate from falling off during the folding and unfolding process. At the same time, the protective box is fixed to the transmission pole by a clamp. The connection is firm and stable, avoiding the loss of the pole license plate due to loosening of the entire device, thus ensuring the safety of the pole license plate from a structural perspective. In addition, the mounting frame adopts an I-shaped design. This structure is not only lightweight but also provides strong support, further enhancing the fixing effect of the license plate frame and the pole license plate, allowing the pole license plate to remain stable under various working conditions. 4. In the non-protective state, the present invention allows the angle of the pole number plate to be adjusted through the control of an electric hydraulic lever. This allows the pole number plate to display information at the appropriate angle under different lighting conditions, making it easier for operators, maintenance personnel, and passers-by to clearly identify it, and solving the problem of unclear information due to angle issues. 5. The cleaning mechanism, consisting of a roller brush, motor, and lead screw within the protective housing of the present invention, automatically cleans the surface of the pole number plate under the control of a controller. The motor drives the lead screw, which in turn moves the sliding seat and linkage shaft, causing the roller brush to roll across the surface of the pole number plate, removing accumulated dust, which is then discharged through the dust outlet. This mechanism is particularly useful in dusty areas, preventing information blurring caused by dust accumulation, ensuring long-term legibility of the pole number plate information, and reducing the workload and cost of manual cleaning. 6. The weight sensor installed between the rotating arm and the mounting bracket of this invention monitors the weight changes of the pole number plate in real time and transmits this data to the controller. If a pole number plate is lost, the weight will change significantly. The controller quickly identifies this abnormality and automatically reports the missing plate to the relevant management system or the staff's terminal device, ensuring that staff are immediately aware and arrange for a replacement, thus avoiding the safety risks caused by the long-term unnoticed loss of the pole number plate. 7. The lighting strip and lamp on the front of the protective box automatically turn on at night to illuminate the pole number plate and information display board, ensuring clear visibility. The information display board is versatile. In addition to posting line maintenance notices and safety warnings, it can also mark specific parameters of the tower and related information of surrounding lines, providing a more comprehensive reference for operation and maintenance personnel, making the information transmission around the tower more efficient and convenient, further enhancing the practical value of the device. 8. The protective box is fixed to the transmission pole through a clamp, which is simple and convenient to install. The clamp can adapt to transmission poles of different diameters. Whether it is a steel pipe tower or an angle steel tower, the device can be firmly installed on different types of towers, which improves the applicability and installation efficiency of the device.

[0031] The fixing mechanism is a clamp 29, which is fixedly mounted on the rear end surface of the protection box 2. The protection box 2 is fixedly connected to the transmission pole 1 through the clamp 29. The working principle of the present invention is as follows: The protective box 2 is fixedly connected to the transmission pole 1 through a clamp 29 fixedly installed on the rear end face, thereby achieving stable installation of the entire device; an opening is provided on one side of the protective box 2 to provide a channel for extending and retracting the pole number plate 7. The mounting base 3 fixed on the top of the inner side of the protective box 2 is rotatably connected to the rotating arm 4. The mounting bracket 5 fixed on one side of the rotating arm 4 is used to fix the license plate frame 6, and the pole license plate 7 is placed in the license plate frame 6. The license plate frame 6 is composed of a left side bar 20, a right side bar 21, a lower side bar 22, an upper side bar 23 and a bottom plate 24. The left side bar 20, the right side bar 21 and the lower side bar 22 are an integrally formed structure. The ends of the upper side bar 23 are fixed to the upper ends of the left side bar 20 and the right side bar 21 by screws. The grooves of the left side bar 20, the right side bar 21, the lower side bar 22 and the upper side bar 23 are interconnected to form a space for placing the pole license plate 7, which plays a role in fixing and protecting the pole license plate 7. The forward extension block 8 fixed on the other side of the rotating arm 4 is provided with a sliding groove 9. The sliding frame 11 at the front end of the telescopic rod of the electric hydraulic rod 10 fixed in the protective box 2 is slidably connected to the mounting seat 3. The sliding column 12 fixed to the sliding frame 11 passes through the mounting seat 3 and is slidably connected to the sliding groove 9. When the electric hydraulic rod 10 is activated under the control of the controller, the sliding frame 11 drives the sliding column 12 to move. The cooperation between the sliding column 12 and the sliding groove 9 drives the rotating arm 4 to rotate around the mounting seat 3, thereby realizing the extension or retraction of the license plate frame 6 and the pole license plate 7 from the opening of the protective box 2. The electric hydraulic rod 10 is connected to the controller signal and is controlled by the controller. A first sliding seat 13 and a second sliding seat 30, slidably mounted on the left and right ends of the inner side of the protective box 2, are fixedly connected to a linkage shaft 14. A roller brush 15, rotatably sleeved on the linkage shaft 14, is used to clean the pole number plate 7. A dust outlet 16 at the bottom of the protective box 2 is used to discharge dust generated during cleaning. A lead screw 17, rotatably mounted on the inner bottom of the protective box 2, is connected to the output end of a motor 18 fixed at one end. A mating block 19, threadedly connected to the lead screw 17, is fixed to the right sliding seat 13. Under the control of a controller, the motor 18 rotates the lead screw 17, causing the mating block 19 to move the sliding seat 13, thereby allowing the roller brush 15 to clean the retracted pole number plate 7. The motor 18 is connected to the controller signal. An information display board 26 is installed in the mounting frame 25 fixed on the front of the protective box 2 for displaying additional information; the lighting strip inside the mounting frame 25 and the lighting 28 on the front of the protective box 2 are connected to the controller signal and can be turned on by the controller when there is insufficient light to illuminate the information display board 26 and the pole number plate 7. The wind speed sensor 27 on the top of the fixed box is connected to the controller signal to monitor the wind speed in real time. When the wind speed is too high, the controller can control the electric hydraulic rod 10 to retract the pole number plate 7 into the protective box 2; the weight sensor between the rotating arm 4 and the mounting frame 5 is connected to the controller signal to monitor the weight changes of the number plate frame 6 and the pole number plate 7. If there is any abnormality, it can be fed back to the controller in time for corresponding processing.

[0032] The embodiments of the present invention are as follows: This invention provides an adjustable transmission pole license plate fixing and protection device. Its protective box 2 is securely mounted on the transmission pole 1 via a clamp 29. The clamp 29 is designed to accommodate transmission poles of varying diameters, ensuring universal and stable installation. The protective box 2 is open on one side, allowing for easy access to the internal components.

[0033] The mounting base 3 is fixed to the top inner side of the protective box 2, and the rotating arm 4 is rotatably connected to the mounting base 3 to form a movable structure. The mounting frame 5 is fixed to the rotating arm 4, and the license plate frame 6 is mounted on the mounting frame 5. When the angle of the pole license plate 7 needs to be adjusted, the controller sends a signal to the electric hydraulic rod 10, and the telescopic rod of the electric hydraulic rod 10 extends or retracts, driving the sliding frame 11 to slide on the mounting base 3. The sliding column 12 on the sliding frame 11 slides within the sliding groove 9 of the forward block 8, thereby rotating the rotating arm 4 around the mounting base 3, realizing the adjustment of the angle of the pole license plate 7 to meet the needs of clear identification of the pole license plate information under different lighting conditions or observation angles.

[0034] Inside the protective box 2, a first sliding seat 13 and a second sliding seat 30 are slidable within the protective box 2. A linkage shaft 14 connects the two sliding seats 13, and a roller brush 15 is rotatably sleeved on the linkage shaft 14. When the motor 18 receives a signal from the controller to start, the output end of the motor 18 drives the lead screw 17 to rotate. The mating block 19, which is threadedly connected to the lead screw 17, drives the first sliding seat 13 to move, and the second sliding seat 30 follows. As a result, the roller brush 15 rolls on the surface of the pole number plate 7, performing a cleaning function. Fallen dust is discharged through the dust outlet 16, keeping the surface of the pole number plate 7 clean and improving its visibility.

[0035] The license plate frame 6 adopts a specific structure, with the left side bar 20, the right side bar 21, and the lower side bar 22 being integrally formed, the bottom plate 24 being fixedly connected to them, and the upper side bar 23 being fixed to the upper ends of the left side bar 20 and the right side bar 21 by screws. This structure facilitates the installation and replacement of the pole number plate 7, and the placement space formed by the grooves of each side bar can effectively fix the pole number plate 7.

[0036] A mounting frame 25 is fixed to the front of the protective box 2, housing an information display panel 26. This panel displays additional information about the transmission pole, such as line routing and maintenance records. A light strip inside the mounting frame 25, controlled by a controller, illuminates the information display panel 26 and the pole number plate 7 in dim conditions, making them easier to view. A light 28 on the front of the protective box 2, also controlled by the controller, further enhances visibility at night or in low-light environments.

[0037] A wind speed sensor 27, mounted atop the protective box 2, monitors wind speed in real time and transmits a signal to the controller. If excessive wind speed threatens the stability of the pole sign, the controller controls the electro-hydraulic lever 10 to adjust the sign's angle to reduce wind resistance. A weight sensor between the rotating arm 4 and the mounting bracket 5 also feeds back a signal to the controller. If the pole sign 7 experiences any abnormal weight changes, such as damage or foreign matter, the controller issues an alarm, alerting maintenance personnel to conduct an inspection and address the issue.
