Description

Technical Field

[0001] The invention relates to the technical field of signboard installation, and in particular to a signboard fixing device. Background Art

[0002] The existing installation method of signboards is to install them on power supply facilities, close to the ground, and the front of the safety key ring signboard faces outward and is perpendicular to the ground. This is done under traditional manual inspection conditions to facilitate staff to identify the safety, health and environmental signs. In the context of promoting "aircraft inspection as the main and human inspection as the auxiliary", human inspections will become less and less, and aircraft inspections will become more and more. When existing drones patrol the lines, the flight path is generally located slightly higher than the live equipment and keeps a safe distance from the equipment. Due to the installation position and angle, the safety key ring sign is difficult to be directly identified by a drone flying in the air. Each time the safety key ring of the equipment is confirmed, the drone needs to descend to the height near the safety key ring installation, and then increase the flight altitude after identification, which greatly reduces the inspection efficiency.

[0003] In the prior art, the patent with patent announcement number CN209822167U discloses a safety and health sign suitable for electric wire towers and easily identifiable by aircraft, which is used to solve the technical problem that the safety and health sign on the existing electric wire tower cannot be directly identified by the patrolling drone due to the installation angle, which greatly reduces the efficiency of drone patrol. Specifically, it includes a first support rod, a second support rod, and a fixing assembly; the fixing assembly includes a first clamping plate and a second clamping plate that are threadedly connected; the first end of the first support rod is connected to the first safety and health sign, and the first safety and health sign is perpendicular to the first support rod, and the second end of the first support rod is connected to a connecting plate, and the connecting plate is connected to the first clamping plate; the first end of the second support rod is connected to the first support rod, and the second support rod is perpendicular to the first support rod, and the second end of the second support rod is connected to the second safety and health sign, and the second safety and health sign is perpendicular to the second support rod.

[0004] It can be seen from this that the prior art usually adopts the arrangement of a horizontal signboard and a vertical signboard at the same time, that is, two signs are fixed in two directions respectively, so as to facilitate manual and drone inspections. However, in the prior art setting method, two signs need to be set up, and there is a situation where the direction of the signboard cannot be changed. The ground staff cannot see the vertical sign clearly, which affects their inspection.

[0005] Therefore, a sign fixing device is urgently needed to solve the above problems. Summary of the invention

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] This embodiment provides a signboard fixing device, and the orientation of the signboard is changeable. Only one signboard is required to meet the needs of manual inspection and drone inspection respectively. The staff can adjust the angle of the signboard to more clearly view the content of the signboard.

[0036] like Figure 1-4 As shown, in this embodiment, the sign fixing device is installed on a utility pole (not shown in the figure) to fix the sign 100. The sign fixing device includes a fixed body 1, a rotating frame 2 and a driving assembly 3. The fixed body 1 includes a mounting member 11 and a fixing member 12 connected to each other. The fixing member 12 is detachably connected to the utility pole to install the fixed body 1 on the utility pole. The driving assembly 3 includes a transmission part 31, a gravity part 32 and a driving rope 33. The gravity part 32 and the driving rope 33 are both connected to the transmission part 31. The transmission part 31 is connected to the rotating frame 2. The gravity part 32 is used to keep the rotating frame 2 in the initial position to facilitate the inspection by the drone. Pulling the driving rope 33 can drive the rotating frame 2 to rotate relative to the mounting member 11 to change the orientation of the sign 100. It can be understood that the initial position is a position that is convenient for the drone to observe during the inspection. For example, when the rotating frame 2 is in the initial position, the sign 100 faces forward. The gravity part 32 is used to keep the rotating frame 2 in the initial position to facilitate the inspection of the drone, that is, in the natural state, the rotating frame 2 is kept in the initial position, and the sign 100 installed in the rotating frame 2 is also kept in the initial position, ensuring the inspection quality and efficiency of the drone. When manual inspection is performed, the drive rope 33 can be pulled to drive the rotating frame 2 to rotate relative to the mounting part 11, thereby rotating the rotating frame 2 from the initial position to a position convenient for inspection personnel to observe, so as to facilitate manual inspection.

[0037] Exemplarily, the angle between the rotating frame 2 and the horizontal plane is 0°-90°, which can be 0°, 15°, 30°, 45°, 60°, etc. The specific angle between the rotating frame 2 and the horizontal plane can be determined according to actual conditions, and this embodiment does not make any specific limitation.

[0038] Furthermore, if Figure 2As shown, the mounting member 11 is a C-shaped frame. Mounting holes 114 are provided at both ends of the mounting member 11. Two rotating shafts (not shown in the figure) are provided on the outer side of the rotating frame 2. The two rotating shafts correspond to the two mounting holes 114 one by one. The rotating shafts pass through the corresponding mounting holes 114, and the transmission part 31 is connected to one of the rotating shafts. It can be understood that by setting the mounting member 11 as a C-shaped frame and providing mounting holes 114 at both ends of the C-shaped frame, the rotating frame 2 is rotatably connected to the C-shaped frame through two rotating shafts provided on the outer side, and the transmission part 31 is connected to one of the rotating shafts to connect the rotating frame 2, thereby facilitating driving the rotation of the rotating frame 2 from the outside of the rotating frame 2. At the same time, one end of the C-shaped frame is open, and one end of the plane where the rotating frame 2 is located can extend outside the C-shaped frame, facilitating the setting of a relatively large rotating frame 2, enabling the font of the sign 100 to be appropriately increased, so as to facilitate drone or manual inspection.

[0039] Exemplarily, as Figure 2 shown, the transmission part 31 is provided at the end of the mounting hole 114 away from the rotating frame 2, that is, the transmission part 31 is located outside the C-shaped frame, thereby reducing the space occupied by the transmission part 31 inside the C-shaped frame and facilitating the setting of a relatively large rotating frame 2.

[0040] Further, continue to refer to Figure 2 , when the rotating frame 2 is in the initial position, the gravity part 32 is located below the transmission part 31 in the direction of gravity. It can be understood that the gravity part 32 is connected to the transmission part 31. When the rotating frame 2 is in the initial position, the gravity part 32 is located below the transmission part 31 in the direction of gravity. At this time, the gravity part 32 only relies on its own gravity to limit the transmission part 31, without the need to set other external forces, which is simple and labor-saving. Moreover, the transmission part 31 is connected to the rotating frame 2. If the rotating frame 2 wants to rotate, it must completely overcome the gravity provided by the gravity part 32, thereby stably keeping the rotating frame 2 in the initial position.

[0041] Further, as Figure 1 and Figure 2 shown, the sign fixing device further includes a gravity block 4. One of the two rotating shafts is connected to the transmission part 31, and the other is connected to the gravity block 4. When the rotating frame 2 is in the initial position, the gravity block 4 is located below the transmission part 31 in the direction of gravity. It can be understood that the other one is connected to the gravity block 4. When the rotating frame 2 is in the initial position, the gravity block 4 is located below the rotating shaft to which it is connected in the direction of gravity. The gravity block 4 relies on its own gravity to limit the rotating frame 2, and the gravity block 4 is connected to the rotating frame 2. If the rotating frame 2 wants to rotate, it must completely overcome the gravity provided by the gravity block 4, further improving the stability of the rotating frame 2 in the initial position and the reliability of drone inspection.

[0042] For example, in this embodiment, the sign fixing device includes both the gravity block 4 and the gravity part 32. When the rotating frame 2 is in the initial position, the gravity block 4 and the gravity part 32 simultaneously apply their own gravity to the rotating frame 2 and limit the rotating frame 2, which greatly improves the stability of the rotating frame 2 in the initial position and further improves the reliability of the drone inspection. Of course, in other embodiments, only the gravity part 32 may be provided.

[0043] Furthermore, if Figure 2 As shown, the driving assembly 3 also includes a winding roller 34, which is rotatably arranged on the mounting member 11, and the driving rope 33 is wound on the winding roller 34. Pulling the driving rope 33 can drive the winding roller 34 to rotate, and the axis of the winding roller 34 is parallel to the axis of the rotating shaft connected to the transmission part 31. The winding roller 34 is coaxially connected to the first gear 5, and the transmission part 31 is coaxially connected to the second gear 6. The first gear 5 is meshed with the second gear 6, so that the rotation of the winding roller 34 can drive the transmission part 31 to rotate, and then drive the rotating frame 2 to rotate through the transmission part 31, so as to change the direction of the sign 100. When manually inspecting, the inspector can pull the driving rope 33 to drive the winding roller 34 to rotate. Since the first gear 5 is meshed with the second gear 6, the winding roller 34 drives the first gear 5 to rotate during the process of the inspector pulling the driving rope 33, and then drives the rotating frame 2 to rotate, so that the rotating frame 2 rotates from the initial position to a position convenient for the inspector to observe, so as to facilitate manual inspection. At the same time, during this process, the driving force applied by the first gear 5 to the second gear 6 is greater than the gravity of the gravity part 32, so as to drive the second gear 6 and the gravity part 32 to rotate. After observation, the inspector can loosen the driving rope 33. At this time, due to the gravity of the gravity part 32, the gravity part 32 will rotate to the bottom of the transmission part 31 in the gravity direction. During this process, the second gear 6, the transmission part 31 and the rotating frame 2 will be driven to rotate, so as to realize the rotation of the rotating frame 2 to the initial position. The second gear 6 drives the first gear 5 to rotate and the winding roller 34 to rotate, and the winding roller 34 reels the driving rope 33 until the rotating frame 2 rotates to the initial position, that is, the rotating frame 2 can rely on the gravity part 32 to rotate to the initial position, and the driving rope 33 can be automatically reeled, which is labor-saving and convenient.

[0044] For example, in this embodiment, the winding roller 34 can be rotatably connected to the mounting member 11 through a fixed shaft (not shown in the figure) and a bearing (not shown in the figure). Specifically, the winding roller 34 is sleeved outside the bearing, one end of the fixed shaft is sleeved inside the bearing, and the other end of the fixed shaft is welded to the mounting member 11. The fixed shaft and the bearing are interference fit, and the bearing and the winding roller are interference fit to achieve the rotatable connection between the winding roller and the mounting member 11. It can be understood that the winding roller 34 rotates relative to the fixed shaft through the bearing, and then rotates relative to the mounting member 11, and the stability is relatively high.

[0045] Furthermore, the diameter of the first gear 5 is smaller than the diameter of the second gear 6. It is understandable that during manual inspection, when the inspector pulls the drive rope 33 to drive the rotating frame 2 to move, the first gear 5 acts as a driving gear, and the second gear 6 meshing with it acts as a driven gear. The diameter of the first gear 5 is smaller than the diameter of the second gear 6, which can reduce the force that the inspector needs to apply to pull the drive rope 33, and the operation is more labor-saving.

[0046] Further, the number of teeth of the second gear 6 is not greater than twice the number of teeth of the first gear 5. When the rotating frame 2 is in the initial position, the length of the drive rope 33 wound by the winding roller 34 is the circumference of the first gear 5. It can be understood that the length of the drive rope 33 wound by the winding roller 34 is the circumference of the first gear 5. Therefore, even if the inspector pulls the drive rope 33, the first gear 5 can rotate at most 1 circle. The rotation angle range of the second gear 6 is 0-180°, that is, the rotation angle range of the driving rotating frame and the gravity part 32 is 0-180°, which can avoid the situation that the gravity part 32 cannot be reset due to the rotation angle greater than 180°, and ensure the stability of the automatic reset of the gravity part 32, that is, in the absence of other external forces, the reliability of the rotating frame 2 to automatically rotate to the initial position by relying on the gravity part 32 is improved. Exemplarily, the number of teeth of the second gear 6 is 1.6 times, 1.8 times, 2 times, etc., of the number of teeth of the first gear 5, and this embodiment does not make specific restrictions on this.

[0047] Of course, in other embodiments, the driving assembly 3 may further include a winding roller 34, the winding roller 34, the rotating shaft and the transmission member are all coaxially arranged, the driving rope 33 is connected to the winding roller 34, the driving rope 33 is wound on the winding roller 34, and pulling the driving rope 33 can drive the winding roller 34 to rotate, so that the transmission member and the rotating frame 2 can be driven to rotate through the winding roller 34. It can be understood that the winding roller 34, the rotating shaft and the transmission part 31 are all coaxially arranged. During manual inspection, the inspector can pull the driving rope 33 to drive the winding roller 34 to rotate, and then directly drive the transmission part 31, the rotating shaft and the rotating frame 2 to rotate. The structure is simple, there is no need to set up multiple transmission structures, and the installation is convenient.

[0048] Further optionally, when the rotating frame 2 is in the initial position, the length of the driving rope 33 wound by the winding roller 34 is not greater than half of the circumference of the winding roller 34. It is understandable that the length of the driving rope 33 wound by the winding roller 34 is less than half of the circumference of the second gear 6. Then, even if the inspector pulls the driving rope 33 to drive the rotating frame and the gravity part 32 to rotate, the maximum rotation angle of the driving rotating frame and the gravity part 32 will not be greater than 180°, which can avoid the situation where the gravity part 32 cannot be reset due to the rotation angle greater than 180°, and ensure the stability of the automatic reset of the gravity part 32, that is, in the absence of other external forces, the reliability of the rotating frame 2 being able to rely on the gravity part 32 to achieve automatic rotation to the initial position is improved.

[0049] Furthermore, as Figure 4 shown, the U-shaped frame (i.e., the mounting member 11) includes a first mounting rod 111, a second mounting rod 112, and a third mounting rod 113. The fixing member 12 is connected to the first mounting rod 111. The second mounting rod 112 and the third mounting rod 113 are perpendicularly connected to both ends of the first mounting rod 111. The sign fixing device further includes a limiting member 7. One end of the limiting member 7 is connected to the first mounting rod 111. The rotating frame 2 is provided with a groove 21. The groove 21 extends to the side surface of the rotating frame 2 facing the first mounting rod 111. The groove 21 is used to accommodate the sign 100. The limiting member 7 is used to abut against the sign 100. It can be understood that the groove 21 extends to the side surface of the rotating frame 2 facing the first mounting rod 111 for accommodating the sign 100. During the rotation of the rotating frame 2, the sign 100 may slide out of the groove 21, and then there may be situations such as injuring the inspection personnel or being damaged after falling. Therefore, the sign fixing device provided in this embodiment further includes a limiting member 7. One end of the limiting member 7 is connected to the first mounting rod 111 and is used to abut against the sign 100. During the rotation of the rotating frame 2, the limiting member 7 is used to abut against the sign 100 to prevent the sign 100 from sliding out of the groove 21, ensuring the reliability of fixing the sign 100 and improving the safety of the inspection personnel.

[0050] Furthermore, a plurality of limiting members 7 are provided at intervals. It can be understood that through the plurality of limiting members 7 provided at intervals, during use, once the sign 100 partially slides out of the groove 21, it will abut against the plurality of limiting members 7, ensuring the limiting reliability of the limiting member 7 for the sign 100. And the sign 100 abuts against the plurality of limiting members 7 simultaneously, which can reduce the damage caused by the direct collision between the limiting member 7 and the sign 100. Exemplarily, in this embodiment, the number of the limiting members 7 is 2. Of course, in other embodiments, the number of the limiting members 7 can be 3, 4, 5, etc. For the specific number of the limiting members 7, it can be determined according to the actual situation.

[0051] Furthermore, the limiting member 7 is arc-shaped. One end of the limiting member 7 is provided with a card slot matching the first mounting rod 111. The limiting member 7 is snap-fitted to the first mounting rod 111 through the card slot, and the limiting member 7 bends towards the rotating frame 2. It can be understood that the limiting member 7 is arc-shaped and the limiting member 7 bends towards the rotating frame 2. The movement route during the rotation of the rotating frame 2 is also arc-shaped, which is convenient for the limiting member 7 to limit the sign 100. And the limiting member 7 is snap-fitted to the first mounting rod 111 through the card slot, which is convenient for installation. When a damaged limiting member 7 is found, it is convenient to directly replace it. At the same time, it is also convenient to adjust the setting number of the limiting members 7, and the operability is strong.

[0052] Of course, in other embodiments, in order to improve the connection stability of the stopper 7, a plurality of fixing holes may be arranged at intervals in the length direction of the first mounting rod 111, corresponding fixing holes may be arranged at one end of the plurality of arc-shaped members, and bolts may be passed through the fixing holes on the first mounting rod 111 and the fixing holes at one end of the arc-shaped members at the same time to fix the plurality of arc-shaped members to the first mounting rod 111. Alternatively, the plurality of arc-shaped members may be fixed to the first mounting rod 111 by directly welding.

[0053] Furthermore, one end of the stopper 7 away from the first mounting rod 111 is located above the mounting member 11, and there is a gap between the stopper 7 and the mounting member 11 in the direction of gravity. It can be understood that one end of the stopper 7 is engaged with the first mounting rod 111, and the other end away from the first mounting rod 111 is located above the plane formed by the mounting member 11, and does not contact the plane where the top surface of the mounting member 11 is located, which is equivalent to that in the direction of gravity, the stopper 7 is effective only above the plane formed by the mounting member 11 for limiting the sign 100. When the side communicating with the groove 21, that is, the rotating frame 2 is located at the initial position, the rotating frame 2 is rotated toward the side of the first mounting rod 111 to the bottom of the plane formed by the mounting member 11, the stopper 7 will no longer be able to abut the sign 100, and the sign 100 can freely enter the groove 21. At this time, the sign 100 can be taken out of the groove 21 for cleaning or replacement, which is convenient for operation.

[0054] Further, the fixing member 12 includes a first arc-shaped member 121, a second arc-shaped member 122 and a fixing bolt 123. The first arc-shaped member 121 is connected to the mounting member 11. The first arc-shaped member 121 and the second arc-shaped member 122 are adapted in shape and connected by the fixing bolt 123. After docking, an inner side surface matching the shape of the electric pole is formed. It can be understood that after docking, the first arc-shaped member 121 and the second arc-shaped member 122 can form an inner side surface matching the shape of the electric pole, which is convenient for fixing the fixing member 12 and the electric pole. Exemplarily, the fixing bolt 123 includes a bolt and a nut matched with the bolt. After the first arc-shaped member 121 and the second arc-shaped member 122 are docked, the bolt passes through the first arc-shaped member 121 and the second arc-shaped member 122 and is fixed by the nut.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
