Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, specifically relating to a fuse crossarm insulation protection platform. Background Technology

[0002] In power lines, the fuse crossarm, installed at the top of the power pole, is an important component of the distribution line. Due to its suitable height and stable structure, the fuse crossarm often becomes a place for birds to perch and nest.

[0003] However, some parts of the fuse devices on the current fuse crossarm are usually in a relatively exposed state. If birds stop and nest here, it often causes a short circuit between these exposed parts and the crossarm, causing the power line to trip and seriously affecting the safe and reliable operation of the power line.

[0004] While existing fuse crossarm insulation protection devices can provide good insulation protection for fuse crossarms and effectively prevent short-circuit tripping caused by bird nests, they require manual installation by operators climbing the poles after the line is de-energized to ensure operator safety. Therefore, they can only be installed during power outages, such as for power line maintenance or new construction projects.

[0005] However, due to increasingly stringent requirements for power supply reliability from users, large-scale power outages are not possible to carry out this installation work once power lines are in normal operation. Therefore, developing an insulated protective platform that allows operators to easily and reliably install the fuse crossarm while the power line is energized without having to climb the pole has become an urgent technical challenge for those skilled in the art.

[0022] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, the fuse crossarm insulation protection platform 10 is used to provide insulation protection for the fuse crossarm (not shown in the figure) installed on the power line pole, and includes a base plate 11, a snap-fit ​​component 12, and a protective plate assembly 13.

[0024] like Figure 1 and Figure 2As shown, the base plate 11 is used to install the snap-fit ​​component 12 and the protective plate assembly 13. It is a rectangular plate with an arc-shaped notch 11a matching the power line pole in the center of one side.

[0025] like Figure 1 and Figure 2 As shown, a snap-fit ​​component 12 is disposed on the lower surface of the other side of the base plate 11 for snapping the base plate 11 onto the fuse crossarm. The snap-fit ​​component 12 includes two pairs of snap-fit ​​plates 121.

[0026] Two pairs of snap-fit ​​plates 121 are located at both ends of the base plate 11. Each pair of snap-fit ​​plates 121 is arranged at intervals in the width direction of the base plate 11 and extends downward from the lower surface of the base plate 11 to form a snap-fit ​​groove 12a that matches the fuse crossarm.

[0027] In this embodiment, each pair of snap-fit ​​plates 121 has a limiting strip 121a on its inner side that matches the thickness of the fuse crossarm.

[0028] In this embodiment, a reinforcing corner plate 121b is provided on the outer side of the connection between each snap-fit ​​plate 121 and the base plate 11; a grid-shaped reinforcing rib 121c is also provided on the outer side of the snap-fit ​​plate 121 near the arc-shaped notch 11a.

[0029] In this embodiment, the length of the snap-fit ​​plate 121 farther away from the arc-shaped notch 11a is greater than the length of the snap-fit ​​plate 121 closer to the arc-shaped notch 11a, so as to facilitate installation and positioning.

[0030] like Figure 1 and Figure 2 As shown, the protective plate assembly 13 is generally U-shaped and is disposed on the upper surface of the base plate 11. The protective plate assembly 13 includes a middle protective plate 131 and two side protective plates 132.

[0031] The intermediate protective plate 131 is located on the other side of the base plate 11 and is arranged along the length of the base plate 11.

[0032] Two operating holes 133 are provided at the connection between the intermediate protective plate 131 and the base plate 11 for inserting the two support columns for mounting the operating rod. These two operating holes 133 are symmetrically arranged and extend along a direction perpendicular to the intermediate protective plate 131 (i.e., the width direction of the base plate 11). In this embodiment, a rectangular notch 11b is provided on the other side of the base plate 11 at the portion corresponding to the two operating holes 133, so that the support columns for mounting the operating rod can be easily inserted into the operating holes 133.

[0033] The two side protective plates 132 are respectively connected to the two sides of the middle protective plate 131.

[0034] In this embodiment, both the middle protective plate 131 and the side protective plate 132 are provided with multiple through holes 134.

[0035] In this embodiment, the inner surfaces of the middle protective plate 131 and the side protective plate 132 are provided with grid-shaped reinforcing ribs 135; the outer side of the connection between the middle protective plate 131 and the base plate 11, and the outer side of the connection between the side protective plate 132 and the base plate 11 are provided with multiple reinforcing corner plates 136; the upper surface of the base plate 11 is also provided with reinforcing strips 111 that are connected to all the reinforcing corner plates 136.

[0036] In this embodiment, the middle protective plate 131 and the side protective plate 132 have the same structure, both consisting of a vertical plate 13a and an inclined plate 13b connected sequentially from bottom to top, with the inclined plate 13b gradually tilting inward from bottom to top.

[0037] In this embodiment, the base plate 11, the snap-fit ​​component 12, and the protective plate assembly 13 are integrally molded from a rigid insulating material, preferably polyurethane.

[0038] In this embodiment, the mounting rod used to install the aforementioned fuse crossarm insulation protection platform 10 onto the fuse crossarm is an insulating operating rod, comprising a rod body, a mounting plate, and two support columns. One end of the mounting plate is connected to the upper end of the rod body; the two support columns are symmetrically arranged at the other end of the mounting plate, and the distance between the two support columns is equal to the distance between the two operating sockets 133.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the installation process of the fuse crossarm insulation protection platform 10 is as follows:

[0040] Step S1: Insert the two support columns for installing the operating rod into the two operating sockets 133 respectively.

[0041] Step S2: Hold the lower end of the installation operating lever and raise the protective platform 10 to the outside above the fuse crossarm, with the arc-shaped notch 11a facing the power line pole.

[0042] Step S3: Move the installation operating lever to first insert the power line pole into the arc-shaped notch 11a, then position the two locking slots 12a directly above the crossarm, and then move the protective platform 10 downwards so that the locking slots 12a are locked onto the crossarm, thereby fixing the protective platform onto the crossarm.

[0043] Step S4: Move the installation operating rod away from the power line pole to disengage the support column from the operating socket 133; this completes the installation process of the protective platform 10.

[0044] Functions and effects of the embodiments

[0045] The fuse crossarm insulation protection platform according to this embodiment has a base plate, a snap-fit ​​component, and a protective assembly. The base plate has an arc-shaped notch on one side of its central portion that matches the power pole. The snap-fit ​​component is located on the lower surface of the other side of the base plate, allowing the base plate to be snapped onto the fuse crossarm. The protective plate assembly is located on the upper surface of the base plate, and is shaped like a "U". It includes a central protective plate on the other side of the base plate and two side protective plates connected to both sides of the central protective plate. The connection between the central protective plate and the base plate has two symmetrically arranged operating holes extending perpendicular to the central protective plate, allowing two support columns for installing the operating rod to be inserted for installation. Therefore, this embodiment not only has good insulation protection but also allows the operator to install the protective platform onto the fuse crossarm by installing the operating rod when the power line is energized, without having to climb the pole. Furthermore, it is convenient, safe, and reliable to operate.

[0046] In addition, since both the middle protective plate and the side protective plate are composed of vertical plates and inclined plates connected sequentially from bottom to top, and the inclined plates gradually tilt inward from bottom to top, the protective effect on the fuse crossarm is ensured.

[0047] Furthermore, because multiple through holes are provided on both the middle and side protective plates, wind resistance is greatly reduced, further improving the stability and reliability of the protective platform.

[0048] In addition, because the inner surfaces of the middle protective plate and the side protective plate are provided with grid-like reinforcing ribs, and the outer sides of the connection between the middle protective plate and the base plate and the connection between the side protective plate and the base plate are provided with multiple reinforcing corner plates, and the upper surface of the base plate is also provided with reinforcing strips that are connected to all the reinforcing corner plates, the structural stability of the protective platform is further ensured.

[0049] In addition, because the snap-fit ​​component includes two pairs of snap-fit ​​plates located at both ends of the base plate, each pair of snap-fit ​​plates is arranged at intervals and extends downward from the lower surface of the base plate, thereby forming a snap-fit ​​groove that matches the fuse crossarm, the structure is simple, easy to manufacture, and easy to install and operate.

[0050] Furthermore, because each pair of snap-fit ​​plates has a limiting strip on its inner side that matches the thickness of the fuse crossarm, the stability of the protective platform installed on the fuse crossarm is further ensured.

[0051] Furthermore, because each snap-fit ​​plate has a reinforcing corner plate on the outside of the connection between the base plate and the snap-fit ​​plate, the structural stability of the snap-fit ​​components is further ensured.

[0052] Furthermore, because the base plate, middle protective plate, side protective plates, and snap-fit ​​plate are made of polycarbonate material in one piece, polycarbonate has better hardness than the soft insulating rubber used in the prior art, making it easier to operate using the installation rod; in addition, the one-piece molding also further improves the structural stability of the protective platform.

[0053] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
