Description

Technical Field

[0001] The utility model relates to the technical field of circuit connection hardware, in particular to an electric power connection plate capable of automatically adjusting connection tension. Background Art

[0002] In power systems, power couplings are typically used to secure insulator strings and circuit conductors. They securely connect insulator strings to conductors or other power components. Insulator strings are key components in power lines, supporting and securing conductors and ensuring adequate insulation distance between conductors and supporting structures such as towers.

[0003] During connection, the power coupler's ends are secured to the insulator string and conductor fittings using its connection holes, bolts, and nuts, thus connecting the insulator string and conductor together to form a stable power transmission channel. When the insulator string and conductor are connected, the conductor exerts its own weight on the power coupler, generally creating excessive tension on the connection. Prolonged excessive tension can damage the connection and shorten its service life. Prolonged excessive tension can cause the connection to wobble, and in severe cases, can lead to disconnection. Utility Model Content

[0004] The purpose of the utility model is to provide an electric power coupling plate which can automatically adjust the connection tension, and can automatically adjust the connection tension between the electric power coupling plate, the insulator string and the conductor.

[0007] As a further optimization of the utility model of an electric power connecting plate capable of automatically adjusting the connection tension, guide grooves are provided on both sides of the mounting hole block, and both side walls of the first connecting hole are in sliding contact with the corresponding bottom walls of the guide grooves.

[0008] As a further optimization of the utility model of the power coupling plate capable of automatically adjusting the connection tension, the positioning member is disc-shaped, and the positioning member and the threaded rod are located on the same axis.

[0009] As a further optimization of the utility model of the power connection plate capable of automatically adjusting the connection tension, a socket for inserting an external lever is provided on the peripheral side of the positioning member.

[0010] As a further optimization of the utility model of the power connecting plate capable of automatically adjusting the connection tension, anti-slip particles are provided on both end surfaces of the positioning piece.

[0011] As a further optimization of the utility model of the power connection plate capable of automatically adjusting the connection tension, a scale for displaying the position of the positioning piece is provided on the plate body.

[0012] As a further optimization of the utility model of the power connection plate capable of automatically adjusting the connection tension, the plate body is provided with an avoidance hole.

[0013] The utility model has the following beneficial effects: in the utility model, a spring is provided between the positioning piece and the mounting hole block, and the threaded movement of the positioning piece and the threaded rod can change the position of the positioning piece, thereby being able to control the elastic force of the spring, and the elastic force of the spring is adjusted according to the specific situation on site, and the sliding position of the mounting hole block is limited according to the elastic force of the spring, so that it slides within a suitable range, and thus the position is adjusted according to its own tensioning force, thereby avoiding excessive tightness or excessive looseness of the tension at the connection between the insulator string and the connecting hardware.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] like Figure 1 As shown, the utility model provides an electric power coupling plate capable of automatically adjusting the connection tension, which can automatically adjust the connection tension between the electric power coupling plate, the insulator string, and the conductor to avoid the connection tension being too tight or too loose. The electric power coupling plate is similar to the prior art in that both include: a triangular plate body 1, a first connection hole 9 is provided at the small diameter end of the plate body 1, and the first connection hole 9 is used to connect to the connection hardware of the insulator string. A second connection hole 2 is provided at the large diameter end of the plate body 1, and the second connection hole 2 is used to connect to the fixed connector on the conductor. At the same time, an avoidance hole 3 is provided on the plate body 1. The avoidance hole 3 is used to avoid the transmission wire that does not need to be connected.

[0018] The present invention differs from the prior art in that the first connecting hole 9 is a rectangular hole, and a mounting hole block 4 is provided within the first connecting hole 9, which slides longitudinally therein. The mounting hole block 4 is connected to the insulator string connection fitting via screws and nuts. The sliding arrangement of the mounting hole block 4 allows the installation position of the insulator string connection fitting to be adjusted, thereby adjusting the spacing between the insulator string and the conductor.

[0019] To limit the position of the mounting block 4, a threaded rod 8 is provided longitudinally on one side of the first connecting hole 9 near the end of the plate body 1. A positioning member 6 is screwed onto the threaded rod 8, and a spring 5 is fixedly connected between the positioning member 6 and the mounting block 4. The elastic force of the spring 5 buffers the stress at the connection, preventing the insulator string from being too tight or too loose at the connection between the connecting hardware. By rotating the positioning member 6, it can be threaded with the threaded rod 8, changing its position. As the spacing between the positioning member 6 and the mounting block 4 changes, the elastic force of the spring 5 is also adjusted accordingly. Adjusting the elastic force according to the specific on-site conditions can further limit the sliding position of the mounting block 4, allowing it to slide within an appropriate range and adjust its position according to its own tension state.

[0020] In the present invention, there are two ways to slide the mounting hole block 4. One is to provide a guide rail on the inner side of the first connecting hole 9, and to provide a guide groove for the guide rail to enter on the side of the mounting hole block 4 corresponding to the guide rail. The guide rail and the guide groove cooperate to limit the sliding of the mounting hole block 4. The other is to provide guide grooves on both sides of the mounting hole block 4, and both side walls of the first connecting hole 9 slide in contact with the bottom walls of the corresponding guide grooves.

[0021] In this utility model, the positioning member 6 is disc-shaped and is coaxial with the threaded rod 8. To facilitate the rotation of the positioning member 6, a socket for inserting an external lever is provided on the periphery of the positioning member 6. Anti-slip particles are also provided on both end surfaces of the positioning member 6.

[0022] In the present invention, a scale showing the position of the positioning member 6 is provided on the plate body 1. The position of the positioning member 6 can be determined by the scale, and thus the elastic state of the spring 5 can be obtained by calculation.

[0023] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
