Description

Technical Field

[0001] The present invention relates to the technical field of power warning signs, and particularly relates to a detachable isolation warning device for the same-pole operation of high-voltage and low-voltage power lines. Background Art

[0002] In the 10kV distribution network, it is quite common for high-voltage and low-voltage power lines to be erected on the same pole. When working on the low-voltage line at such a site, if the high-voltage line of all high-voltage and low-voltage power lines on the same pole within the operation range is de-energized, the following problems exist: (1) expanding the power outage scope; (2) increasing the risk of high-quality service; (3) increasing the workload and safety risks of power-on and power-off operations and safety measure settings; (4) reducing the power sales volume; (5) due to the control limit on the number of power outages of the 10kV high-voltage line, it may also lead to the inability to implement all the work in a timely manner, or the safety control risks brought by arranging a large number of personnel to carry out the work at one time. If the high-voltage line of some high-voltage and low-voltage power lines on the same pole within the operation range is not de-energized, it is possible that the staff may wrongly climb towards the 10kV live line direction, thus causing a personal electric shock injury and death safety accident due to insufficient safety distance from the live equipment.

[0003] Currently, the safety control measures for the high-voltage line of some high-voltage and low-voltage power lines on the same pole without power outage mainly include: (1) indicating the relevant hazard points and pre-control measures in the work ticket and the standardized operation manual; (2) arranging a special person to monitor on-site.

[0004] From the actual working situation, the above safety control measures may have the following problems in implementation: (1) there may be omissions of the hazard points and pre-control measures in some work tickets and standardized operation manuals; (2) the special person's monitoring may be ineffective due to reasons such as insufficient working ability and lack of responsibility.

[0005] In summary, the existing control measures mainly rely on the special person's monitoring. If the monitoring personnel fail to monitor properly or the staff make mistakes, it is easy to cause insufficient safety distance. Therefore, there is a lack of a technical prevention device with reliable isolation and warning effects to ensure the safety distance from the 10kV live equipment. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that when the high-voltage lines of some high- and low-voltage power lines on the same pole within the operation range are not de-energized, it is possible that the staff may climb in the direction of the 10 kV energized line by mistake, thus causing a personal electric shock and casualty safety accident due to insufficient safety distance from the energized equipment. The purpose is to provide a detachable isolation warning device for the operation of high- and low-voltage power lines on the same pole. By adopting this solution, warning signs can be set on the electric pole between the energized equipment and the working point, preventing the staff from causing a personal electric shock and casualty safety accident due to insufficient safety distance from the 10 kV energized equipment due to mistakes; and enabling the operators to clearly see the warning slogans from all directions below the electric pole, thus significantly playing an effective warning role.

[0012] Second warning signs are provided on both sides of the first warning sign. Taking the warning plane of the first warning sign as the reference plane, one side of the second warning sign is connected to the side of the first warning sign, and the other side of the second warning sign inclines upward in the direction away from the first warning sign.

The illustrative embodiments and descriptions thereof of the present invention are only used to explain the present invention and do not limit the present invention.

[0042] Embodiment 1

[0044] Installation belt 1, the installation belt 1 is wound circumferentially around the electric pole 2;

[0045] Warning signboard 3, there are several warning signboards 3, and several warning signboards 3 are all connected to the installation belt 1 and are evenly distributed along the circumference of the electric pole 2;

[0046] The warning sign 3 includes a first warning sign 31. One end of the first warning sign 31 is connected to the installation belt 1 through a connecting piece 4. The other end of the first warning sign 31 slopes upward in a direction away from the axis of the electric pole 2, and the warning plane of the first warning sign 31 is parallel to the diameter of the electric pole 2.

[0047] Second warning signs 32 are provided on both sides of the first warning sign 31. Taking the warning plane of the first warning sign 31 as the reference plane, one side of the second warning sign 32 is connected to the side of the first warning sign 31, and the other side of the second warning sign 32 slopes upward in a direction away from the first warning sign 31.

[0048] In the prior art, in the operation range where high-voltage and low-voltage power lines are erected on the same pole in a 10 kV distribution network, if the high-voltage line of some high-voltage and low-voltage power lines on the same pole within the operation range is not de-energized, it may be possible that due to the staff climbing in the direction of the 10 kV energized line by mistake, resulting in a personal electric shock injury and death safety accident due to insufficient safety distance from the energized equipment. This solution provides a detachable isolation warning device for the operation of high-voltage and low-voltage power lines on the same pole. Adopting this solution, a warning sign can be set on the electric pole 2 between the energized equipment and the working point, preventing the staff from causing a safety accident of insufficient safety distance from the 10 kV energized equipment due to mistakes; and enabling the operators to clearly see the warning slogans from all directions below the electric pole 2, thus significantly playing an effective warning role.

[0049] In the specific solution, such as Figure 1 and Figure 2As shown in the figure, it includes an installation belt 1 and warning signs 3. The installation belt 1 is wound around the electric pole 2. The two ends of the installation belt 1 can be connected by means of buckles or the like, and its length is adjustable. The installation position of the installation belt 1 is between the energized equipment and the working point. A number of warning signs 3 are evenly distributed in the length direction of the installation belt 1, that is, evenly distributed along the circumference of the electric pole 2. On the outer surface of the warning sign 3, there are warning graphics and slogans of "Do not climb, high voltage danger!" printed on it and highlighted in a special color, such as red. At this time, the energized equipment and the working point can be separated, so as to prevent the staff from causing a safety accident of insufficient safety distance from the 10 kV energized equipment due to mistakes, resulting in personal electric shock and casualties; among them, the warning sign 3 includes a first warning sign 31 and a second warning sign 32. The first warning sign 31 is set to tilt upward, and the angle between its plane and the horizontal plane is preferably 150°. On both sides of the first warning sign 31, there are second warning signs 32. The second warning signs 32 are set to tilt, and the angle between the surface of the second warning sign 32 and the surface of the first warning sign 31 is preferably 145°; on the outer surfaces of the first warning sign 31 and the second warning sign 32, there are warning graphics and slogans of "Do not climb, high voltage danger!" printed on them. At this time, through the tilted first warning sign 31 and the tilted second warning sign 32, the operating personnel can clearly see the warning slogans from all directions below the electric pole 2, avoiding the operating personnel from being unable to see clearly at some oblique viewing angles and thus ignoring its danger. Among them, both the installation belt 1 and the warning sign 3 are made of insulating materials.

[0050] Please refer to Figure 4 and Figure 5 As a specific implementation method for quickly installing the warning sign 3 on the installation belt 1, it is set as follows: The connecting piece 4 includes a shell. Inside the shell, there is a first cavity 41 and a second cavity 42. Both ends of the first cavity 41 penetrate through the left and right sides of the shell. The first cavity 41 is used for passing through the installation belt 1; the upper end of the second cavity 42 is open. One end of the first warning sign 31 is fixed with an insertion plate 33 that is adapted to the size of the second cavity 42. The insertion plate 33 is used for inserting into the second cavity 42; the surface of the shell close to the electric pole 2 is an arc surface that is adapted to the wall surface size of the electric pole 2.

[0051] It can be understood that in this solution, there is a connecting piece 4. Inside the connecting piece 4, there is a first cavity 41 that runs through horizontally. The first cavity 41 is used for the installation belt 1 to pass through, so that the connecting piece 4 is installed on the installation belt 1. There are several connecting pieces 4, which are the same in number as the warning signs 3. Inside the connecting piece 4, there is also a second cavity 42. The upper end of the second cavity 42 is open. At the lower end of the first warning sign 31, there is a vertically arranged insertion plate 33. At this time, the insertion plate 33 can be inserted into the second cavity 42, so that the warning sign 3 is installed on the connecting piece 4. Among them, both the insertion plate 33 and the connecting piece 4 are arc-shaped. The installation belt 1 is tightened, so as to fix the connecting piece 4 on the side wall of the electric pole 2; the connecting piece 4 is made of insulating materials.

[0052] See also Figure 5 In this embodiment, the first cavity 41 and the second cavity 42 are sequentially arranged in a direction away from the pole 2; by arranging the first cavity 41 at a position close to the pole 2, the fastening effect of the mounting belt 1 on the connector 4 is improved.

[0053] Please continue reading Figure 5 As a specific implementation method for making the mounting belt 1 firmly wrapped around the pole 2, it is configured as follows: the surface of the shell close to the pole 2 includes an upper wall surface 43 and a lower wall surface 44, a gap is left between the upper wall surface 43 and the lower wall surface 44, and the gap is connected to the first cavity 41; along the length direction of the mounting belt 1, an adhesive strip 11 is provided on the inner side of the mounting belt 1, and the adhesive strip 11 can extend out of the gap from the first cavity 41;

[0054] It can be understood that the inner surface of the shell is an upper wall 43 and a lower wall 44, and a horizontal gap is left between the upper wall 43 and the lower wall 44, and an adhesive strip 11 is provided on the inner side of the mounting belt 1. The length of the adhesive strip 11 is set along the length direction of the mounting belt 1. The width of the adhesive strip 11 is adapted to the size of the gap, and its thickness can extend from the gap, so that the mounting belt 1 can be stably bonded to the pole 2 through the adhesive strip 11.

[0055] Please continue reading Figure 5 As a specific implementation method for preventing the plug board 33 and the mounting belt 1 from loosening, it is configured as follows: the housing is provided with an intermediate wall 45 for separating the first cavity 41 and the second cavity 42, the upper and lower parts of the intermediate wall 45 are provided with a plurality of through holes, each through hole is provided with a limiting device 5, the limiting device 5 comprises a slide bar 51, the slide bar 51 is slidably located in the through hole, and both ends extend out of the through hole, one end of the slide bar 51 is used to abut against the plug board 33, the slide bar 51 located at the upper part is used to abut the mounting belt 1 against the upper wall 43, and the slide bar 51 located at the lower part is used to abut the mounting belt 1 against the lower wall 44;

[0056] It can be understood that there are several limit devices 5 on the middle wall 45, and the limit devices 5 are located at the upper and lower positions of the middle wall 45, which are adapted to the positions of the upper wall 43 and the lower wall 44. The limit devices 5 include a slide bar 51, and both ends of the slide bar 51 respectively abut against the plug plate 33 and the mounting belt 1, thereby fixing the plug plate 33 and the mounting belt 1 in the connecting member 4 to prevent the plug plate 33 from loosening or even causing the warning sign 3 to fall off, and can also abut against the upper and lower positions of the mounting belt 1 respectively, thereby preventing the mounting belt 1 from rolling up in the first cavity 41 or even falling off from the gap.

[0057] See also Figure 6, as a specific implementation for facilitating the insertion of the plug board 33 and adjusting the position of the connecting member 4, it is set that: the through hole is a stepped hole, the end of the stepped hole close to the second cavity 42 is the large-diameter end, a first limiting plate 52 is sleeved on the part of the sliding rod 51 extending out of the large-diameter end, and the cross-sectional dimension of the first limiting plate 52 is larger than that of the large-diameter end; a spring 53 is sleeved on the sliding rod 51, and both ends of the spring 53 are respectively connected to the first limiting plate 52 and the step of the stepped hole; one end of the sliding rod 51 is provided with a first sphere 54, and the first sphere 54 rolls along the insertion direction of the plug board 33; on the part of the other end of the sliding rod 51 extending out of the small-diameter end of the stepped hole, there is a second limiting plate 57, the cross-sectional dimension of the second limiting plate 57 is larger than the cross-sectional dimension of the small-diameter end of the stepped hole, and the other end of the sliding rod 51 is provided with a second sphere 55, and the second sphere 55 rolls along the length direction of the mounting belt 1;

[0058] It can be understood that, due to the existence of the limiting device 5, in order to insert the plug board 33, the limiting device 5 needs to have corresponding elasticity. A first limiting plate 52 is provided on the part of the sliding rod 51 extending out of the large-diameter end of the stepped hole, and a spring 53 is provided between the first limiting plate 52 and the step of the stepped hole. Thus, during the downward insertion of the plug board 33, it can squeeze the sliding rod 51, so that the sliding rod 51 is compressed, leaving enough space for the plug board 33 to move downward; the cross-sectional dimension of the first limiting plate 52 is larger than that of the large-diameter end, and the cross-sectional dimension of the second limiting plate 57 is larger than that of the small-diameter end, both of which are used to prevent the sliding rod 51 from falling off; a first groove is provided at one end of the sliding rod 51, a rotating shaft is fixed in the first groove, and a first sphere 54 is rotatably connected to the rotating shaft. The first sphere 54 extends out of the first groove, and its rotation direction is set along the insertion direction of the plug board 33, that is, vertically arranged. At this time, after the plug board 33 is inserted, by squeezing the first sphere 54, the sliding rod 51 moves backward, and the first sphere 54 rolls on the plug board 33, thereby guiding the plug board 33, enabling the plug board 33 to be installed quickly, and enabling both ends of the sliding rod 51 to have a pressing force on the plug board 33 and the mounting belt 1; a second limiting plate 57 is provided at the other end of the sliding rod 51, the second limiting plate 57 is provided with a second groove, a rotating shaft is fixed in the second groove, and a second sphere 55 is rotatably connected to the rotating shaft. The rotation direction of the second sphere 55 is the length direction of the mounting belt 1, that is, it can rotate horizontally. Thus, after being pressed tightly, the position of the connecting member 4 can be finely adjusted along the length direction of the mounting belt 1, which is convenient for adjustment according to the specific working range.

[0059] Please continue to refer to Figure 6 , as a specific implementation for enabling the plug board 33 to smoothly squeeze into the position of the first sphere 54 during the insertion process, it is set that: a guiding member 56 is provided above the first sphere 54, the guiding member 56 is fixedly connected to the first limiting plate 52, and the upper side of the guiding member 56 is provided with a guiding arc surface adapted to the lower end of the plug board 33;

[0060] It can be understood that a guide member 56 is provided above the first sphere 54, and the upper end of the guide member 56 is provided with an arc surface, so as to increase the arc guiding length. The lower end of the insertion plate 33 is provided with a chamfer, so that the insertion plate 33 can be gradually pressed along the arc surface until the first sphere 54 lands on the side surface of the insertion plate 33.

[0061] Please refer to Figure 7 , as a specific implementation manner for improving the fixing effect of the insertion plate 33 after the insertion plate 33 is inserted, it is set that: a plurality of hemispherical grooves 331 adapted to the first sphere 54 are provided on the side surface of the insertion plate 33;

[0062] It can be understood that a plurality of hemispherical grooves 331 are provided on the side surface of the insertion plate 33, so that a part of the first sphere 54 can smoothly slide out into the hemispherical grooves 331. During the specific installation process, only by increasing the acting force of manpower, the first sphere 54 can be made to slide out of the hemispherical grooves 331.

[0063] Please refer to Figure 1 , as a specific implementation manner of the stable warning sign 3, it is set that: it further includes a support rod 6, and both ends of the support rod 6 are respectively connected to the lower surface of the first warning sign 31 and the outer surface of the connecting member 4. The lower surface of the first warning sign 31 and the outer surface of the connecting member 4 are both provided with support grooves 7 for the support rod 6 to be inserted;

[0064] It can be understood that an inclined support rod 6 is provided between the first warning sign 31 and the connecting member 4, and the support rod 6 plays a role in supporting the warning sign 3; the direction of the support groove 7 is towards the direction of the support rod 6, which is convenient for realizing quick disassembly.

[0065] Specific working principle: When installing the isolation warning device of this solution, first select the installation position, which needs to be installed between the live equipment and the working point. Then pass the installation belt 1 through the first cavities 41 of a plurality of connecting members 4, install a plurality of connecting members 4, and then wind the installation belt 1 around the electric pole 2. Through the buckle at the end of the installation belt 1, the installation belt 1 is tightened. At this time, press the installation belt 1 to make the adhesive strip 11 stably adhered to the electric pole 2; then take out a plurality of warning signs 3, and make the insertion plate 33 tightly inserted from the outer side wall of the second cavity 42.
