[0038] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0039] Figure 1 A schematic diagram of an adjustable signboard device according to an embodiment of the present application.

[0040] As shown in Figure 1 An embodiment of the present application provides an adjustable signboard device 100 for a power line tower, which comprises:

[0041] An adjustable structure 130;

[0042] A support frame 120 is arranged on the pair of adjustable structures 130, and the support frame 120 is fixedly connected with the adjustable structures 130.

[0043] A signboard body 110 is arranged on the support frame 120, and the adjustable structure 130 is configured to drive the signboard body 110 to reciprocally move through the support frame 120.

[0044] The adjustable signboard device 100 comprises a pair of adjustable structures 130, and the support frame 120 is arranged on the pair of adjustable structures 130, which can improve the support strength of the support frame 120 and the adjustable structures 130 on the signboard body 110, improve the stability of the signboard body 110, and reduce the influence of earthquakes and strong winds on the signboard body 110. Meanwhile, the specific position of the signboard body 110 can be adjusted through the adjustable structure 130, the distance of the signboard body 110 can be adjusted according to the needs, and the flexibility of the use of the signboard body 110 is improved.

[0045] Figure 2 A schematic diagram of an adjustable signboard device according to another embodiment of the present application.

[0046] As shown in Figure 2As shown, a connecting leg is arranged between the signboard body 110 and the support frame 120, and the connecting leg is hinged to the support frame 120; the adjustable signboard device 100 further comprises a telescopic rod 150, a fixed end of the telescopic rod 150 is hinged to the support frame 120, and a telescopic end of the telescopic rod 150 is hinged to the connecting leg; the telescopic rod 150 can be an electric telescopic rod, and the telescopic length of the telescopic rod 150 is controlled remotely, so that the angle between the signboard body 110 and the support frame 120 can be changed, and the signboard body 110 is further applicable to different scenes, and the application range of the adjustable signboard device 100 is improved.

[0047] In a feasible implementation, the adjustable signboard device 100 further comprises a driving mechanism 140 connected with the adjustable structure 130, and the driving mechanism 140 drives the movement of the adjustable structure 130.

[0048] The adjustable structure 130 is driven to move by the driving mechanism 140, the movement of the adjustable structure 130 is realized, and then the support frame 120 and the signboard body 110 on the adjustable structure 130 are driven to move, so that the application range of the adjustable signboard device 100 is expanded. For example, the signboard body 110 arranged at a warning line at a seaside can adjust the position of the signboard body 110 according to the ebb and flow line; when a strong wind weather occurs, the signboard body 110 can be appropriately inclined to avoid that the wind force is entirely applied to the signboard body 110, and the stability of the signboard body 110 is ensured, so that the adjustability of the signboard body 110 is very necessary, and the use scenarios are not enumerated again.

[0049] In a feasible implementation, the driving mechanism 140 is a ball screw assembly or a telescopic cylinder.

[0050] The driving mechanism 140 can be a ball screw assembly, the nut 144 of the ball screw assembly is fixedly connected with the adjustable structure 130, and the moving part (the sliding block 132) on the adjustable structure 130 is driven to move on the fixed part (the guide rail 131), so that the reciprocating movement of the adjustable structure 130 is realized. The driving mechanism 140 can also be a telescopic cylinder, the telescopic end of the telescopic cylinder is fixedly connected with the moving part on the adjustable structure 130, and the reciprocating movement of the moving part on the fixed part is driven by the telescopic end.

[0051] Figure 4 A schematic view of the driving mechanism of an embodiment of the present application.

[0052] In a feasible implementation, as shown in Figure 4 The ball screw assembly comprises:

[0053] The fixed frame 141 is arranged on one side of the adjustable structure 130;

[0054] A screw rod 142 is arranged in the fixing frame 141 and is rotationally connected with the fixing frame 141, and at least one end of the screw rod 142 extends out of the fixing frame 141;

[0055] A driving motor 143 is fixedly connected with the extended end of the screw rod 142;

[0056] A nut 144 is threadedly connected with the screw rod 142, and the adjustable structure 130 is fixedly connected with the nut 144.

[0057] In this way, the driving mechanism 140 and the adjustable structure 130 are arranged side by side, which can improve the stability of the adjustable signboard device 100. In addition to the adjustable structure 130 being fixedly connected with the ground or the tower, the fixing frame 141 is also fixedly connected with the ground or the tower, and multiple connection points are used for connection, so that the stability of the adjustable signboard device 100 can be improved, and the damage caused by disasters such as strong wind and earthquake can be reduced.

[0058] Specifically, the screw rod 142 is rotationally arranged in the fixing frame 141, the screw rod 142 is externally threaded, the nut 144 is sleeved on the screw rod 142, and the nut 144 is threadedly connected with the screw rod 142. The nut 144 is fixedly connected with the moving part (the sliding block 132) of the adjustable structure 130, so as to avoid the nut 144 from rotating with the screw rod 142. The driving motor 143 drives the screw rod 142 to rotate, so that the nut 144 on the screw rod 142 can move on the screw rod 142, and in turn drives the moving part (the sliding block 132) to move. When the driving motor 143 is reversed, the nut 144 is reversely moved, and the reciprocating movement of the moving part (the sliding block 132) on the adjustable structure 130 is realized.

[0059] It can be understood that the driving motor 143 and the telescopic rod 150 can be powered by the line of the tower, so as to reduce the addition of external lines. Alternatively, a separate battery can be arranged to power the driving motor 43 and the telescopic rod 150. When the battery is out of power, an alarm can be sent, so that the staff can replace the battery in time, and the reliability of the adjustable signboard device 100 can be ensured.

[0060] It should be noted that the movement of the moving part (the sliding block 132) is driven by the steel ball screw assembly, which can improve the stability and precision of the movement of the sliding block 132 and can be adjusted slightly.

[0061] Figure 3 A schematic view of the adjustable structure of one embodiment of the present application.

[0062] In one possible implementation, as shown in Figure 3 the adjustable structure 130 includes:

[0063] a guide rail 131;

[0064] The slider 132 is arranged on the guide rail 131, and the driving mechanism 140 is fixedly connected with the slider 132, and the slider 132 reciprocates on the guide rail 31;

[0065] The adjustable signboard device 100 comprises a pair of adjustable structures 130, and the driving mechanism 140 is located outside the pair of guide rails 131.

[0066] It should be noted that the adjustable structure 130 comprises the guide rail 131 and the slider 132 arranged on the guide rail 131, and the guide rail 131 is fixedly connected with the ground or the tower, thereby improving the stability and reliability of the adjustable signboard device 100. In the present application, two adjustable structures 130 are arranged, and a square support frame 120 is arranged on the pair of adjustable structures 130, thereby further improving the stability of the adjustable signboard device 100. Thus, two driving mechanisms 140 are required to drive the two adjustable structures 130 respectively, and the two driving mechanisms 143 can be controlled to work synchronously through a synchronous algorithm, so as to ensure the synchronous movement of the sliders 132 of the two adjustable structures 130, thereby improving the stability and reliability of the movement of the signboard body 110.

[0067] In a feasible embodiment, the guide rail 131 is provided with a retainer 133, the retainer 133 and the guide rail 131 form a containing groove, the slider 132 is provided with a circulating channel 134, at least part of the circulating channel 134 and the containing groove form a channel space, and the circulating channel 134 is provided with a steel ball 135.

[0068] The retainer 133 can improve the stable support of the steel ball 135, the driving mechanism 140 drives the slider 132 to move on the guide rail 131, so that the steel ball 135 in the slider 132 can move in the circulating channel 135 and the channel space, the friction coefficient is reduced, the gap between the slider 132 and the guide rail 131 is reduced, the deformation in the movement process is reduced, the device is suitable for the earthquake environment, the loss caused by the vibration is reduced, and the device can be used after the earthquake. The reduced friction coefficient can also reduce the power consumption, improve the transmission efficiency of the driving mechanism 140, reduce the energy consumption, and improve the economy. The transmission realized by the steel ball 135 can also bear the radial, axial and torque load at the same time, thereby being suitable for the environment with strong wind, so that the adjustable signboard device 100 is suitable for complex environments, and the application range of the adjustable signboard device 100 is improved.

[0069] It should be noted that the steel ball 135 is arranged to provide the only contact between the guide rail 131 and the sliding block 132, and when the sliding block 132 moves relative to the guide rail 131, the steel ball 135 rolls along the circulating channel 134, and the sliding friction between the guide rail 131 and the sliding block 132 is converted into the rolling friction between the steel ball 135 and the guide rail 131 and the steel ball 135 and the sliding block 132, a continuous circulation is formed in the circulating channel 134, the friction between the guide rail 131 and the sliding block 132 caused by reciprocating movement is avoided, and the service life of the adjustable structure 130 is improved; and the jamming caused by long-time sliding friction can also be avoided, and the stability of the adjustable structure 130 in operation is improved.

[0070] It can be understood that there are usually two circulating channels 134 and two accommodating grooves, that is, two groups of steel balls 135, which further improve the stability and reliability of the sliding block 132 moving on the guide rail 131.

[0071] In a possible implementation, the pair of guide rails 131 are provided with oil scraping sheets 136 on the sides facing away from each other, the oil scraping sheets 136 are provided with grooves matched with the guide rails 131, the oil scraping sheets 136 are arranged at both ends of the sliding block 132 in the length direction, and the oil scraping sheets 136 are provided with sealing covers 137 which are detachably connected with the sliding block 132.

[0072] The material of the oil scraping sheet 136 is rubber.

[0073] It should be noted that in order to further reduce the friction coefficient of the steel ball 135 in the circulating channel 134, it is usually necessary to inject lubricating liquid or lubricating grease into the circulating channel 134, and therefore part of the lubricating liquid or lubricating grease will be left or leaked on the guide rail 131. The oil stains and dust on the guide rail 131 can be scraped off by the oil scraping sheets 136 arranged at both ends of the sliding block 132, the shape of the oil scraping sheets 136 is matched with the guide rail 131, and the oil scraping sheets 136 can scrape off the oil stains and dust on the guide rail 131 after moving with the sliding block 132, so as to ensure the smoothness of the sliding block 132 moving on the guide rail 131, avoid the jamming of the sliding block 132 caused by the oil stains and dust, and further reduce the energy loss of the driving mechanism 140. The sealing cover 137 is arranged outside the oil scraping sheet 136 to avoid the oil stains and dust on the oil scraping sheet 136 from splashing, the oil scraping sheet 136 in the sealing cover 137 is cleaned regularly, and the oil scraping sheet 136 is replaced in time when wear is found.

[0074] It should be noted that the oil scraping sheet 136 is usually made of rubber, which can avoid the wear of the guide rail 131 caused by the oil scraping sheet 136, and also can make the oil scraping sheet 136 interfere with the guide rail 131 to improve the working effect of the oil scraping sheet 136.

[0075] In an embodiment, the adjustable structure 130 further comprises an oil inlet channel 138, which is arranged at one end of the sliding block 132, and one end of the oil inlet channel 138 is connected with an external oil pipe, and the other end of the oil inlet channel 138 is in communication with the accommodating groove or circulation channel 134.

[0076] The lubricating oil forms an oil film between the steel ball 135 and the guide rail 131 and the sliding block 132, avoids direct contact between metals, changes dry friction into fluid lubrication friction, reduces the friction coefficient, prevents the steel ball 135 and the guide rail 131 and the sliding block 132 from being abraded due to metal adhesion or contaminants, prolongs the service life of the adjustable structure 130, and the lubricating oil can also take away friction heat, avoids material deformation caused by temperature rise during movement, and the formed oil film can also prevent water vapor and acidic substances from directly contacting the guide rail 131, reduces the risk of oxidation and chemical corrosion, and makes the adjustable structure 130 suitable for humid environments (rain disasters) and corrosive environments. The injection of the lubricating oil can also reduce operating noise and improve the stability of the movement of the sliding block 132.

[0077] In an embodiment, the signboard body 110 is made of a metal matrix composite material or a ceramic matrix composite material, and the signboard body 110 is provided with a reflective film layer or a luminescent film layer.

[0078] The metal matrix composite material has the advantages of high strength and light weight, and is suitable for environments with strong wind and heavy rain; the ceramic matrix composite material has high hardness and is resistant to sand and dust abrasion, is suitable for windy and sandy environments and mine environments, has no aging problem, has a longer service life, is not conductive and does not burn, and is suitable for power facilities and environments that need to be fireproof,

[0079] It should be noted that the reflective film layer is arranged, and after being irradiated by light, the signboard body 110 can be seen at night or in fog, and even at a distance of hundreds of meters, without the need for additional power supply, improving the safety and reliability of the adjustable signboard device 100. The luminescent film absorbs sunlight or light during the day, and can emit light for several hours at night, and can also be clearly seen in a lightless environment.

[0080] It can be understood that the sign body 110 is provided with a connecting hole or a clamping groove matched with the support frame 120, so as to facilitate quick connection and disassembly of the adjustable structure 130. According to the field environment and the visual angle requirement, the sign body 110 is adjusted to a suitable position through the guide rail 131, and the sign body 110 is adjusted to a suitable angle through the telescopic rod 150. After the driving mechanism 140 and the telescopic rod 150 are stopped, direct locking is performed, so as to ensure the stability of the sign body 110. When the sign body 110 needs to be replaced, the old sign body 110 can be disassembled from the support frame 120, and the connecting end with the telescopic rod 150 is disassembled, and then other new sign body 110 is replaced.

[0081] In the present application, the terms "first" and "second" are used only for descriptive purposes and are not to be construed as indicating or implying relative importance. The term "a plurality of" means two or more, unless otherwise expressly specified.
