Description

Technical Field

[0001] This utility model relates to the field of power transmission equipment technology, specifically to a splicing mechanism and a power pole. Background Technology

[0002] After natural disasters, mountainous and coastal areas urgently need to restore power quickly; in particular, power poles often need to be re-erected due to damage caused by natural disasters.

[0003] Due to natural disasters, road access is difficult, and the transportation of power equipment is often carried out by drones. However, drones have limited payload (generally not exceeding 50kg), while traditional power poles are quite heavy (according to the situation of domestic transmission lines, most are poles with a tip diameter of φ190mm and a length of 12m or 15m, and this type of composite pole weighs about 185kg), making transportation difficult and affecting the rapid restoration of power in special areas, effectively reducing the efficiency of power restoration. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a splicing mechanism and a utility pole, aiming to solve the problem of the large weight of the utility pole and the difficulty of transporting it by drones.

[0005] This utility model provides a splicing mechanism, including,

[0006] The first splicing component has an insertion interface on it;

[0007] The second connector is plugged into the interface.

[0008] The sealing assembly includes a filling cavity disposed between the first splice and the second splice, and mounting grooves disposed on both sides of the filling cavity. Both ends of the filling cavity are provided with sealing rings, and the filling cavity is filled with an adhesive layer. The mounting grooves are located on the inner wall of the insertion interface.

[0009] In one embodiment, the mounting groove is an annular shape coaxially arranged with the first splicing component, and the sealing ring is correspondingly disposed in the two mounting grooves, with the inner annular surface of the sealing ring in sealing contact with the second splicing component. The inner annular surface of the sealing ring is an inclined surface with the same slope as the outer wall of the second splicing component.

[0010] In one embodiment, the sealing assembly further includes an injection hole disposed on the side wall of the first splice, the injection hole communicating with the filling cavity. The sealing assembly also includes an outlet hole disposed on the side wall of the first splice, the outlet hole communicating with the filling cavity. The injection hole and the outlet hole are located on opposite sides of the filling cavity. Both the injection hole and the outlet hole are through holes extending inward from one outer wall of the first splice, passing through the second splice, and then through the other side of the second splice. A retaining pin is inserted into both the injection hole and the outlet hole.

[0011] This utility model also discloses a utility pole, including a splicing mechanism, and further comprising,

[0012] The pole has a first and a second splice at its two ends. There are at least two poles, which are spliced ​​together sequentially. A protective layer is provided on the outer surface of the pole.

[0013] Compared with existing technologies, it has the following beneficial effects:

[0014] This utility pole utilizes a segmented assembly design. In areas where transportation is inconvenient, it can be quickly transported to the pole's location using drones, ensuring rapid power restoration in mountainous and coastal areas and effectively improving restoration efficiency. Adjacent pole segments are secured with adhesive after assembly, ensuring a strong joint. Furthermore, the design of the sealing ring, injection hole, and dispensing hole prevents adhesive leakage from both ends of the filling cavity during injection and facilitates easy assessment of whether the adhesive is fully filled.

[0025] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0026] Example 1:

[0027] like Figures 1 to 3 As shown, this utility model provides a splicing mechanism, including,

[0028] The first splicing component 1 is provided with a plug interface 11;

[0029] The second splicing component 2 is inserted into the plug interface 11;

[0030] The sealing assembly 3 includes a filling cavity 31 disposed between the first splice 1 and the second splice 2, and mounting grooves 34 disposed on both sides of the filling cavity 31. Both ends of the filling cavity 31 are provided with sealing rings 32, and the filling cavity 31 is filled with an adhesive layer 33. The mounting grooves 34 are located on the inner wall of the insertion interface 11.

[0031] Specifically, the splicing mechanism of this utility model includes a first splicing member 1 with an insertion interface 11 and a second splicing member 2 inserted into the insertion interface 11. After the second splicing member 2 is inserted into the insertion interface 11, a filling cavity 31 is formed between the first splicing member 1 and the second splicing member 2 due to the sealing ring 32 spaced between them. Adhesive is filled into the filling cavity 31 as an adhesive layer 33, ensuring a tight connection between the first splicing member 1 and the second splicing member 2 and guaranteeing connection strength. Simultaneously, the sealing ring 32 and the adhesive layer 33 also provide a sealing function to prevent water from entering. The adhesive used is epoxy resin.

[0032] Example 2:

[0033] like Figures 1 to 3As shown, in another embodiment of this utility model, the mounting groove 34 is an annular shape coaxially arranged with the first splicing member 1. The sealing ring 32 is correspondingly disposed in the two mounting grooves 34, and the inner annular surface of the sealing ring 32 is in sealing contact with the second splicing member 2. The sealing ring 32 is specifically installed in the mounting groove 34 on the inner wall of the insertion interface 11, and partially extends to the outside of the mounting groove 34, ensuring that there is a filling cavity 31 between the first splicing member 1 and the second splicing member 2 filled with adhesive layer 33. When the sealing ring 32 is placed, in order to prevent the sealing ring 32 from shifting when the first splicing member 1 and the second splicing member 2 are spliced, the sealing ring 32 can be adhered to the mounting groove 34 with adhesive to ensure the firmness of the sealing ring 32. Since the sealing ring 32 is arranged at both ends of the filling cavity 31 and the sealing ring 32 is in sealing contact with the second splicing member 2, the sealing ring 32 also plays the role of sealing the filling cavity 31, preventing glue from flowing out from both ends of the filling cavity 31 when glue is poured into the filling cavity 31.

[0034] See Figure 1 In this embodiment, the inner annular surface of the sealing ring 32 is an inclined surface with the same slope as the outer wall of the second splicing component 2. The use of an inclined surface with the same slope as the outer wall of the second splicing component 2 ensures the contact area between the sealing ring 32 and the outer wall of the first splicing component 1, thereby guaranteeing a tight seal. Alternatively, the sealing ring 32 can also be a uniformly circular sealing ring with both inner and outer annular surfaces.

[0035] Example 3:

[0036] As another embodiment of this utility model, such as Figure 4 As shown, the sealing assembly 3 in this embodiment also includes an injection hole 35 disposed on the side wall of the first splice 1, and the injection hole 35 is connected to the filling cavity 31. Adhesive is injected into the filling cavity 31 through the injection hole 35 to form an adhesive layer 33.

[0037] See Figure 4 In this embodiment, the sealing assembly 3 also includes an adhesive outlet 36 disposed on the side wall of the first splice 1, and the adhesive outlet 36 is connected to the filling cavity 31. The adhesive outlet 36 is provided to expel air from the filling cavity 31 when adhesive is injected into the filling cavity 31 from the adhesive injection hole 35.

[0038] See Figure 4 In this embodiment, the glue injection hole 35 and the glue outlet hole 36 are located on both sides of the filling cavity 31.

[0039] See Figure 4 and Figure 5 In this embodiment, both the glue injection hole 35 and the glue dispensing hole 36 are through holes that extend inward from the outer wall of one side of the first splicing component 1, pass through the second splicing component 2, and then pass through the other side of the second splicing component 2. Both the glue injection hole 35 and the glue dispensing hole 36 are fitted with fixing pins 37.

[0040] Reference Figures 1 to 4The adhesive outlet 36 is also used to determine whether the filling cavity 31 is full of adhesive by observing whether the adhesive is discharged from the adhesive outlet 36 when filling the filling cavity 31 with adhesive. Specifically, during the adhesive injection, the first splicing end and the second splicing end are laid flat and spliced ​​together, with the adhesive outlet 36 facing upwards. Then, adhesive is injected into the filling cavity 31 through the adhesive injection hole 35. Due to gravity, the adhesive flows downwards into the filling cavity 31. After the filling cavity 31 is filled, the adhesive flows out from the adhesive outlet 36, which indicates that the filling cavity 31 is full of adhesive.

[0041] Reference Figure 4 and Figure 5 Both the injection hole 35 and the dispensing hole 36 are through holes that penetrate both sides of the first splicing end. After the glue is injected, a fixing pin 37 can be inserted into the injection hole 35 and the dispensing hole 36. After the adhesive cures, it also has the function of reinforcing the fixing pin 37 to improve the connection strength after splicing. During the glue injection, one end of the injection hole 35 and the dispensing hole 36, as well as the part on the second splicing end, is sealed with a cap, sealing film, or sealing gasket that can be opened to prevent the glue from leaking out during the glue injection. After the glue is injected, the fixing pin 37 is inserted, and the fixing pin 37 opens the seal and extends to the other side, and the glue cures.

[0042] Example 4:

[0043] like Figure 6 and Figure 7 As shown, this utility model also discloses a utility pole, including a splicing mechanism, and further comprising,

[0044] The rod body 4 has the first splicing component 1 and the second splicing component 2 located at its two ends.

[0045] See Figure 7 There are at least two rods 4, and the rods 4 are spliced ​​together in sequence so that multiple rods 4 can be spliced ​​together in sequence.

[0046] At least two poles 4 are spliced ​​together in sequence to form a power pole, which facilitates the rapid re-erection of poles after natural disasters to quickly restore power. Specifically, multiple poles 4 are transported to the required locations by drones, spliced ​​at the pole locations, and then erected by hoisting equipment. Of course, a pole pit needs to be dug at the pole locations before erection.

[0047] See Figure 8 In this embodiment, a protective layer 41 is provided on the outer surface of the rod 4. The protective layer 41 is specifically made of polyurethane, which protects the rod 4 while giving the surface of the rod 4 a certain degree of hydrophobicity, reducing the penetration of water into the interior of the rod 4.

[0048] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
