Description

Technical Field

[0001] This utility model belongs to the field of power fittings technology, specifically a stable windproof and pressure-equalizing shielding ring. Background Technology

[0002] The equalizing shielding ring serves both to equalize voltage and to provide shielding, making it a crucial component of insulator strings. Currently, most equalizing shielding rings used in China are made of steel or aluminum, with the support frame directly welded to the ring body. The support frame is then fixed to the hardware or equipment to be equalized and shielded. Conventional equalizing ring bodies are made of 4mm thick aluminum tubing, but due to its thin wall thickness, a secure weld to the support frame cannot be guaranteed, making it prone to damage in windy conditions.

[0003] Chinese utility model patent CN210326912U discloses an equalizing shielding ring. The ring body and the bracket are integrally cast from aluminum. The ring body is hollow and slotted, making it lightweight. The U-bolts and V-grooves on the bracket facilitate the positioning and fixing of the object to be equalized and shielded. The slotted ring body is equipped with drainage holes, which facilitates later cleaning and prevents water seepage that could lead to internal water accumulation and affect performance.

[0004] While one-piece casting can solve the problem of shielding ring stability in windy weather to some extent, its high manufacturing cost and large size and weight limit the convenience of transportation and storage. Once damaged, the replacement of one-piece shielding ring often involves a larger amount of engineering work and higher costs, which is not as convenient and quick as split-type shielding rings. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A stable windproof equalizing shielding ring includes a pair of ring half-tubes, which are joined together to form the main body of the equalizing shielding ring. A bracket is installed on the main body of the equalizing shielding ring. Insertion holes are opened at both ends of the ring half-tubes, and a liner is inserted into the insertion hole. The length of the liner is twice the depth of the insertion hole. The ring half-tubes and the liner are welded together. A retainer is snapped onto the ring half-tubes, and an insertion tube is connected to the retainer. The bracket is inserted into the insertion tube.

[0008] The cannula and the ferrule are welded together to form a whole. The ferrule has a notch on its side, and the diameter of the notch is smaller than the diameter of the ferrule. The inner diameter of the cannula is equal to the diameter of the end of the support.

[0009] The ferrule is provided in a set and is symmetrically snapped onto the annular half tube. The connection between the ferrule and the annular half tube is welded and fixed. The bracket is inserted into the tube and then welded and fixed.

[0010] The bracket is made of bent metal pipe. A flat section is symmetrically pressed in the center of the bracket. Multiple through holes are opened on the flat section. When the bracket is assembled onto the body of the equalizing shield ring, the through holes on the two brackets are aligned. A connecting bolt for fixing the two brackets is inserted through the through hole.

[0011] A retaining ring is integrally installed in the center of the liner. The diameter of the retaining ring is larger than the diameter of the insertion hole but smaller than the diameter of the end of the ring half tube.

[0012] When the liner is inserted into the socket, the side of the retaining ring abuts against the end of the ring half tube. The ends of the pair of ring half tubes and the retaining ring directly form an annular cavity, which is filled by welding.

[0013] The liner is a solid structure, and the liner is made of the same material as the annular half-tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] (1) The present invention adopts a split structure for the shielding ring, which is fixed by welding after being connected by the liner. Firstly, the split shielding ring is more flexible and can adapt to various complex spatial layouts and installation environments, strengthen the rigidity and stability of the overall structure, and resist the influence of external mechanical forces. Secondly, the design of the liner provides additional support points for the two segments, which is equivalent to adding a reinforcing structure to the weak link of the shielding ring, which can significantly increase the overall rigidity of the shielding ring, making it less prone to deformation or twisting when facing lateral wind forces. Moreover, the method of connecting and welding the liner can ensure the precise alignment and uniform filling of the weld, thereby improving the strength and sealing of the welded part. The presence of the liner provides a stable welding interface.

[0016] (2) The present invention uses welding to connect the liner and the ring half pipe, so that a continuous and strong metal connection is formed at the joint. The welded part can achieve high strength and high sealing, thereby effectively resisting the dynamic load of gust impact. The use of the liner also ensures the positional accuracy of the two sections when they are docked, avoiding structural instability caused by misalignment. High-precision assembly reduces the vibration amplitude under wind load and reduces the risk of fatigue damage.

[0017] (3) The present invention is provided with a ferrule and a tube on the shielding ring. The bracket is connected to the shielding ring through the ferrule and the tube. The connection of the ferrule and the tube provides a solid foundation and ensures that the various parts of the shielding ring bracket are closely matched. Even when subjected to wind force, it can maintain good structural integrity and stability. The ferrule and the tube allow a certain adjustment range, which is convenient for precise alignment and fine adjustment. It ensures that the bracket is stably positioned on the corresponding position of the shielding ring, thereby improving the overall installation efficiency and accuracy. In addition, the ferrule and the tube indirectly increase the contact surface between the bracket and the shielding ring, thereby improving the wind resistance and ensuring stability.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0028] Figure 1 This is a structural diagram of the stable windproof and pressure-equalizing shielding ring in this embodiment. The pressure-equalizing shielding ring in this embodiment includes a pair of annular half-tubes 100, which are joined together to form the main body of the pressure-equalizing shielding ring. A bracket 103 is installed on the main body of the pressure-equalizing shielding ring.

[0029] In this embodiment, the equalizing shielding ring body is a split structure. Therefore, for connection, this embodiment has insertion holes 101 at both ends of the ring half tube 100, and a liner 104 is inserted into the insertion hole 101. A pair of ring half tubes 100 are connected by the liner 104, and the connection between the ring half tube 100 and the liner 104 is welded to form an equalizing shielding ring body. Furthermore, in order to ensure connection stability, the length of the liner 104 is twice the depth of the insertion hole 101, so that when the liner 104 is inserted into the insertion hole 101, it can completely fill the space of the insertion hole 101, thereby ensuring the strength of the connection of the ring half tubes 100 and improving the wind resistance of the spliced ​​equalizing shielding ring. The liner 104 is a solid structure to improve wind resistance, and the liner 104 and the ring half tube 100 are made of the same material, which facilitates welding.

[0030] See Figure 2 , Figure 3 as well as Figure 4In this embodiment, a retainer 102 is snapped onto the annular half-tube 100, and an insertion tube 1021 is connected to the retainer 102. A bracket 103 is inserted into the insertion tube 1021. The insertion tube 1021 and the retainer 102 are welded together to form a single unit. A notch is provided on the side of the retainer 102, and the diameter of the notch is smaller than the diameter of the retainer 102. The inner diameter of the insertion tube 1021 is equal to the diameter of the end of the bracket 103. In this embodiment, to make the connection between the bracket 103 and the equalizing shielding ring body more stable, the retainer 102 and the insertion tube 1021 are provided. The retainer 102 and the insertion tube 1021 indirectly increase the contact area between the bracket 103 and the shielding ring body, thereby improving the wind resistance and ensuring stability. Furthermore... Typically, the bracket 103 and the shielding ring body have two welding ends. Therefore, in this embodiment, the ferrule 102 is provided in a set and symmetrically snapped onto the ring half tube 100. The connection between the ferrule 102 and the ring half tube 100 is welded and fixed. After the bracket 103 is inserted into the insertion tube 1021, it is also welded and fixed. The connection between the ferrule 102 and the insertion tube 1021 provides a stable foundation, ensuring a tight fit between the shielding ring and the bracket 103. Even when subjected to wind force, it can maintain good structural integrity and stability. The ferrule 102 and the insertion tube 1021 allow a certain range of adjustment, which is convenient for precise alignment and fine adjustment, ensuring that the bracket 103 is stably positioned in the corresponding position on the shielding ring body, thereby improving the overall installation efficiency and accuracy.

[0031] See Figure 4 In this embodiment, the bracket 103 is formed by bending a metal pipe. A flat section is symmetrically pressed on the central position of the bracket 103. The bracket 103 is connected to the shielding ring body through the sleeve 102 and the insertion tube 1021. However, the end of the bracket 103 is suspended in the air and is easily affected by wind and swaying at high altitudes. Therefore, this embodiment has multiple through holes on the flat section. When the bracket 103 is assembled onto the equalizing shielding ring body, the through holes on the two brackets 103 are aligned. A connecting bolt 1031 is connected through the through hole and fixes the two brackets 103.

[0032] See Figure 1 , Figure 3 as well as Figure 5In this embodiment, the two annular half-tubes 100 are joined together by a liner 104. When the liner 104 is inserted into the insertion hole 101 of the annular half-tube 100, the ends of the oppositely positioned annular half-tubes 100 fit together. However, welding can only be performed at the joint, which means that the inner side of the joint cannot be reinforced by welding. Therefore, in order to eliminate the above-mentioned disadvantages, this embodiment has a retaining ring 1041 integrally provided in the center of the liner 104. The diameter of the retaining ring 1041 is larger than the diameter of the insertion hole 101 but smaller than that of the annular half-tube. In this embodiment, when the liner 104 is inserted into the insertion hole 101, the side of the retaining ring 1041 abuts against the end of the annular half-tube 100. Since the diameter of the liner 104 is smaller than the end of the annular half-tube 100, a portion of the end section of the annular half-tube 100 is exposed. Thus, the ends of a pair of annular half-tubes 100 and the retaining ring 1041 directly form an annular cavity. The annular cavity is filled by welding, thereby increasing the welding area and ensuring the strength of the weld.

[0033] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
