Description

Technical Field

[0001] This utility model relates to the field of power transmission line monitoring technology, specifically to an online monitoring device for power transmission lines that is easy to install and disassemble. Background Technology

[0002] Online monitoring devices for transmission lines, directly installed on high-voltage live conductors, have strict limitations on their casing profile. They must have a roughly smooth cylindrical structure to avoid point discharge or excessive wind resistance in strong electric fields, ensuring operational safety and stability. This shape constraint requires the device to meet extremely high smoothness requirements in the closed state, thus limiting the design of its opening and closing structure.

[0003] Currently, most hinge structures use a through-type long shaft for opening and closing, which only provides a limited opening angle while maintaining a smooth profile. This limited opening severely restricts the operating space of internal equipment, making the installation, debugging, maintenance, and replacement of core components difficult and increasing the complexity of maintenance work. Furthermore, this through-type long shaft hinge structure is generally designed to be non-disassembly-free, making the disassembly and assembly process cumbersome and inconvenient, seriously affecting maintenance efficiency. Therefore, there is an urgent need for a new connection structure that can improve the efficiency of disassembly, assembly, and debugging of internal components while meeting the requirements of the outer casing profile. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide an online monitoring device for power transmission lines that is easy to install and disassemble.

[0005] The online monitoring device for transmission lines that is easy to assemble and disassemble according to the present invention includes an upper compartment and a lower compartment, which are connected by a hinge structure, and a hollow structure is formed between the upper compartment and the lower compartment to allow the transmission line to pass through. The hinge structure includes an upper hinge seat, a lower hinge seat, an upper mounting groove, a lower mounting groove, and a short shaft assembly. The upper hinge seat and the upper mounting groove are both located at the bottom edge of the upper compartment, and the lower hinge seat and the lower mounting groove are both located at the top edge of the lower compartment. The upper hinge seat is located at both ends of the upper mounting groove, and the lower mounting groove is located at both ends of the lower hinge seat. The upper hinge seat and the lower hinge seat are respectively embedded in the lower mounting groove and the upper mounting groove. The short shaft assembly includes a short shaft and a plug. The short shaft is fixed in the shaft hole of the upper hinge seat by the plug, and one end of the short shaft is located in the shaft hole of the upper hinge seat, while the other end of the short shaft is inserted into the end of the shaft hole of the lower hinge seat.

[0006] Preferably, the shaft hole of the lower hinge seat includes countersunk holes at both ends of the lower hinge seat for accommodating the ends of the short shaft.

[0007] Preferably, the short shaft includes a first insertion portion and a second insertion portion, wherein the radius of the first insertion portion is larger than that of the second insertion portion; The first insertion part is used to insert into the shaft hole of the upper hinge seat, and the second insertion part is used to insert into the shaft hole of the lower hinge seat. A stepped structure is formed between the first insertion part and the second insertion part, and the end face of the stepped structure is opposite to the end face of the lower hinge seat.

[0008] Preferably, the upper hinge seat is integrally formed and connected to the upper compartment body, and the lower hinge seat is integrally formed and connected to the lower compartment body.

[0009] Preferably, the plug includes a conductive rubber plug, and the conductive rubber plug is interference-fitted with the shaft hole of the upper hinge seat.

A smooth cylindrical surface is formed between the outer shell of the upper compartment, the edge of the upper mounting groove, the outer side of the lower hinge seat, and the outer shell of the lower compartment.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention replaces the traditional through-type long shaft with a split short shaft assembly. During maintenance, only the end caps need to be removed to quickly separate the upper and lower compartments, completely solving the problem of insufficient maintenance space caused by the limited opening and closing angle. The end caps effectively prevent accidental detachment in strong vibration environments while ensuring axial restraint.

[0016] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0017] This utility model discloses an online monitoring device for power transmission lines that is easy to assemble and disassemble. By replacing the traditional through-type long shaft structure with a split short shaft assembly, the upper and lower compartments can be quickly separated by removing the end caps during maintenance. This completely solves the problem of insufficient maintenance space caused by the limited opening and closing angle. The end caps effectively prevent accidental detachment in strong vibration environments while ensuring axial restraint. The split structure avoids the risk of hinge jamming caused by deformation of the long shaft. The entire assembly is completely embedded in the hinge structure, ensuring that the device maintains a smooth cylindrical profile when closed, which meets the anti-discharge requirements of high-voltage lines for the equipment profile.

[0018] According to the online monitoring device for power transmission lines that is easy to install and disassemble provided by this utility model, such as Figures 1-3 As shown, the device includes an upper compartment 1 and a lower compartment 2, which are connected by a hinge structure. A hollow structure is formed between the upper compartment 1 and the lower compartment 2 to allow power transmission lines to pass through. The hinge structure includes an upper hinge seat 101, a lower hinge seat, an upper mounting groove, a lower mounting groove 201, and a short shaft assembly. The upper hinge seat 101 and the upper mounting groove are both located at the bottom edge of the upper compartment 1, and the lower hinge seat and the lower mounting groove 201 are both located at the top edge of the lower compartment 2. The upper hinge seat 101 is located at both ends of the upper mounting groove, and the lower mounting groove 201 is located at both ends of the lower hinge seat. The upper hinge seat 101 and the lower hinge seat are respectively embedded in the lower mounting groove 201 and the upper mounting groove. The short shaft assembly includes a short shaft 302 and a plug 301. The short shaft 302 is fixed in the shaft hole of the upper hinge seat 101 by the plug 301, and one end of the short shaft 302 is located in the shaft hole of the upper hinge seat 101, while the other end of the short shaft 302 is inserted into the end of the shaft hole of the lower hinge seat.

[0019] Traditional through-type long shaft designs are intended only for flipping between the upper and lower compartments, without considering disassembly. Therefore, the long shaft is typically fixed in the hinge seat's shaft hole, limiting operation to a limited opening between the upper and lower compartments, resulting in low efficiency. This invention replaces the through-type long shaft with a split short shaft, enabling quick assembly and disassembly between the upper compartment 1 and the lower compartment 2. When disassembly or repair of internal components is required, the upper compartment 1 and lower compartment 2 can be completely separated into two main bodies by removing the short shafts at both ends, facilitating maintenance. Furthermore, this split structure avoids the risk of hinge jamming caused by long shaft deformation.

[0020] In a preferred embodiment, the shaft hole of the lower hinge seat includes countersunk holes at both ends of the lower hinge seat for accommodating the end of the short shaft 302, wherein the depth of the countersunk hole is greater than the protrusion height of the end of 302. By setting the shaft hole as a countersunk hole, the processing cost and assembly difficulty can be significantly reduced.

[0021] In a preferred embodiment, the short shaft 302 includes a first insertion portion and a second insertion portion, the radius of the first insertion portion being larger than that of the second insertion portion. The first insertion portion is used to insert into the shaft hole of the upper hinge seat 101, and the second insertion portion is used to insert into the shaft hole of the lower hinge seat. A stepped structure is formed between the first insertion portion and the second insertion portion, and the end face of the stepped structure is opposite to the end face of the lower hinge seat. Specifically, the short shaft assembly also includes a short shaft bushing 303. The second insertion portion of the short shaft 302 is inserted into the short shaft bushing 303, and the short shaft bushing 303 is inserted into the shaft hole of the lower hinge seat. The end of the short shaft bushing 303 is provided with a radially protruding gasket structure, which is disposed between the end face of the stepped structure and the end face of the lower hinge seat. The short shaft bushing 303 can preferentially withstand the rotational friction of the short shaft 302, avoid wear on the hinge seat shaft hole wall, and can significantly reduce hinge swaying and abnormal noise under wind vibration environment, and compensate for the cumulative error of the hinge seat mounting surface.

[0022] In a preferred embodiment, the upper hinge seat 101 is integrally formed and connected to the upper chamber 1, and the lower hinge seat is integrally formed and connected to the lower chamber 2. When the upper chamber 1 and the lower chamber 2 are closed, a smooth cylindrical surface is formed between the outer shell of the upper chamber 1, the outer side of the upper hinge seat 101, the edge of the lower mounting groove 201, and the outer shell of the lower chamber 2; a smooth cylindrical surface is formed between the outer shell of the upper chamber 1, the edge of the upper mounting groove, the outer side of the lower hinge seat, and the outer shell of the lower chamber 2. By making the overall outline nearly cylindrical, good anti-discharge performance can be achieved.

[0023] In a preferred embodiment, the plug 301 includes a conductive rubber plug, which is interference-fitted with the shaft hole of the upper hinge seat 101. The outer end face of the upper hinge seat 101 is a curved surface that smoothly transitions with the outer shell of the upper chamber 1; the outer end of the plug 301 is provided with a curved surface that smoothly transitions with the outer end face of the upper hinge seat 101. The conductive rubber plug, through the interference fit, can achieve continuous elastic compression, maintaining a reliable seal of the shaft hole gap even under strong vibration conditions, while establishing a low-resistance path between the short shaft and the hinge seat, completely eliminating the risk of discharge caused by static electricity accumulation.
