Description

NEST REMOVAL

Technical Field

[001] The present invention belongs to the field of mechanical engineering, more specifically accessories applied to transmission line and power distribution poles.

Introduction

[002] The present invention relates to a retractor, more specifically a bird's nest retractor applicable to various types of insulators for transmission line poles or power distribution.

Fundamentals

[003] Bird nests are very common to be found in places like windows, roofs, buildings, traffic signs and mainly, poles.

[004] The nests become a problem when made on poles on the support crosses of the lines close to the insulators, since the birds and their nests, which are made of straw and/or clay, become electrical conductors when wet . Consequently, both the birds and their nests increase the risk of a short circuit in the electrical network, which can activate its protection system, which interrupts the supply of electrical energy. In addition, this electrical discharge can also cause the birds to be affected and, not infrequently, killed.

[005] To solve this issue, there are several types of nest spacers designed to be installed at the top of the insulator, on the pole arm (crosspiece) or that require a complex installation, often involving disconnection from the power grid and a logistics that depend on multiple people to be carried out.

[006] The retractors need to be simple parts, easy to handle and adaptable to various models of insulators and transformers and that allow a good coexistence between the bird and the structure of the energy pole.

[007] Finally, it is desirable that the nest retractor be an object that is easy to install, requires little maintenance and has a simple and low cost manufacturing.

state of the art

[008] Known state-of-the-art solutions for nature deters dealt with herein can be verified in state-of-the-art documents such as the Chinese document CN2255654, entitled "Bird-proof shade for high-voltage power line insulation", which presents a utility model such as a bird-proof sombrero that is shaped like a disc body with a center hole, the disc body has a thickness, the front of the disc body has downward gradient, and the outer edge of the part back of the disc body is provided with an end.

[009] Document CN2255654, despite presenting a bird-proof shade for high voltage power line insulator, does not present a versatile solution to be used in different types of insulators, being limited only to circular formats with a certain diameter , since the sombrero only has a single hole of a single diameter. In addition, the invention as disclosed by CN2255654 also reveals a hat which, in its main modalities, requires the dismantling of the electrical insulator for its passage, not being quick and easy to install.

[010] Another patent document whose solution can be mentioned is document CN204146215, entitled "Energy transmission line helmet for bird prevention", refers to a power line helmet power transmission for bird prevention, comprising an umbrella sheet, wherein the center of the umbrella sheet is provided with a circular hole suitable for the cross section of the insulator. The leaf comprises a left semi-circular umbrella leaf and a right semi-circular umbrella leaf, being fixed together by means of connecting screws which are connected at opposite linear edges.

[011] However, document CN204146215 does not describe an object formed with a single body, but an element composed of two halves fixed together by screws, making installation difficult in the field, since it would involve more assembly steps, in addition to the difficulty of the correct positioning of the tool and the screw, considering that the assembly will be carried out at the top of a pole. Furthermore, as in the previously described document, the diameter of the hole in the helmet is unique, which prevents the use of more than one different type of insulator.

[012] Finally, it is worth mentioning that several state-of-the-art solutions can be verified in other patent documents such as CN211320875, WO2007106051, CN205791385 and JP5660384. In these documents, disadvantages are also identified in relation to modularity and assembly complexity, in addition to the disadvantages already described for the aforementioned documents.

[013] The state of the art does not provide robust, simple and low-cost solutions for a nest retractor applied to an insulator. In addition, the state of the art presents solutions without versatility for application in different types of insulators and which demand dexterity and complexity of installation in the field, often requiring disconnection from the electrical network.

[014] There is therefore space for a nest retractor, which: a) is formed in a single body piece; b) enables coupling to the base of various types and sizes of insulators, vertical and horizontal; c) guarantee a product of high quality, low cost, low consumption of raw materials and with high robustness for the proposed application; d) allows a simple installation with the use of standard hot sticks, without disconnecting from the electrical network and without using an articulated platform or ladder; and e) guarantee a durable and maintenance-free product during its useful life.

Goals

[015] The objective of the invention is, therefore, to provide a bird's nest retractor applied to an insulator, according to the characteristics of claim 1 of the attached set of claims.

[019] Additionally, the spacer (100) is designed to allow its quick and practical coupling to the base of the insulator, covering a wide range of formats and diameters of the base of the insulator. It should be noted that the process of installing the spacer (100) is not impaired by the number or size of the insulating units that this insulator has, since the coupling of the spacer (100) can be performed only by opening and closing it, when the retractor (100) is pressed against the base.

[020] In addition, the spacer (100) can be used in different types and sizes of insulators, such as insulators of ceramic pillar, polymeric, glass pin, ceramic pin, polymeric pin, horizontal, vertical and in bushing transformer.

[021] The side regions (110) of the retractor (100) each comprise a primary hollow portion (111), a first rib (112), a secondary hollow portion (113) and a second rib (114), in that the side regions (110) have a rounded shape and are arranged, preferably, in pairs and on opposite sides of the retractor (100).

[022] The primary hollow portion (111) of the lateral region (110) has a rounded upper and lower contour, which follows the shape of the lateral region (110), of which it is part, and neighbors the posterior region (130) ) and the rib (112), in which the primary hollow portion (111) preferably has a straight shape at the end that borders the rib (112).

[023] Additionally, the primary hollow portion (111) has a shape and size configuration that allows enough flexibility of the retractor (100) so that it can be opened and closed without permanent deformation of the retractor (100). [024] The first rib (112) of the lateral region (110) is found between the hollow portions (111, 113), having a straight shape and accompanying the height of the hollow portions (111, 113), being the main responsible for maintain the firmness of the lateral region, preventing compressive and shearing efforts from damaging or disturbing the coupling of the retractor (100), in addition to preventing damage caused by rain, wind, bird landing, among others.
