Description
Technical Field
[0001] The utility model relates to the technical field of power transmission devices, and more specifically to a power transmission device with adjustable angle. Background Art
[0002] Cable is a wire that transmits electric energy and is made up of one or more mutually insulated conductors twisted together and sheathed in a sealed sheath. It is mainly composed of conductors, insulation layers, shielding layers, sheaths, etc. These components together ensure the safety and reliability of cables during power transmission. As a medium for power transmission, cables can transmit electric energy from power stations or substations to the user end. In the power system, cables play an important role in connecting various electrical equipment and transmitting electric energy. In addition to transmitting electric energy, cables can also be used to transmit various signals, such as control signals, communication signals, etc. This makes cables play an important role in both power systems and communication systems.
[0003] At present, when laying cables at high altitudes, they are usually installed in an overhead manner, that is, a stable connection is established between two connection points through a steel cable, and the cable is overhead installed at the bottom of the steel cable through a connecting mechanism, thereby completing the overhead arrangement of the cable. However, the high-voltage overhead cable should be kept as vertical as possible when placed, because if the angle is too large, it is easy to cause current overload, cable overheating, and even fire and other safety accidents. The traditional connecting mechanism is usually only a single steel wire structure. The steel wire is bent to fit the bottom shape of the cable, and the two ends of the steel wire are bent to form hooks. The steel cable is connected through the hooks to complete the overhead installation of the cable. However, due to the strong wind at high altitudes, the connection stability and integrity between the traditional connecting structure and the steel cable and the cable are insufficient, which can easily cause cable fluctuations, thereby affecting the verticality of the cable, and also causing wear between the cable and the connecting mechanism. In view of this, we propose an angle-adjustable power transmission device. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to actual needs, and provide an angle-adjustable power transmission device to solve the technical problem that the current traditional connection structure has insufficient connection stability and integrity between the steel cable and the cable, which easily leads to cable fluctuations and thus affects the verticality of the cable, and also causes wear between the cable and the connection mechanism.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an angle-adjustable power transmission device, comprising a steel cable with a plurality of cable overhead installation components detachably hung at the bottom;

A limiting mechanism for rotationally limiting the semicircular block is provided on the top of the inner wall of the installation groove.
[0009] The utility model designs a hanging mechanism, and realizes a stable connection by hanging the hanging mechanism and the steel cable. During the overhead cable installation, the cable overhead supporting assembly can be toggled to drive the cable to deflect, and at the same time, the U-shaped plate drives the ratchet to rotate, so as to adjust the angle of the cable to ensure the verticality of the cable in the overhead installation. After the cable angle adjustment is completed, it is limited by the unidirectional rotation limit of the ratchet and the ratchet, that is, the cable overhead supporting assembly cannot be reset in the opposite direction of the toggling rotation, so that the cable overhead supporting assembly carries the cable to maintain the current angle, thereby improving the stability and integrity between the steel cable, the cable and the cable overhead supporting assembly, and is not prone to fluctuations when dealing with high-altitude wind, which is beneficial to ensuring the verticality of the overhead cable installation and reducing the surface wear of the cable caused by insufficient stability.
[0010] Preferably, the semicircular block is symmetrically opened on the outer edge surface relative to the plane end to form a limiting groove, and the semicircular block is located inside the limiting groove and a rotating shaft is fixedly installed, both ends of the rotating shaft can be rotatably connected to the inner wall of the installation groove, and one end of the rotating shaft can be rotatably passed through the connecting arm and is fixedly connected to a knob.
[0011] Preferably, the limiting mechanism comprises a spring whose top end is fixedly connected to the top of the inner wall of the installation groove, and whose bottom end is fixedly connected to a limiting ball, and the limiting ball is abutted and arranged in the limiting groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model designs a hanging mechanism, and realizes a stable connection by hanging the hanging mechanism and the steel cable. During the overhead installation of the cable body, the cable overhead supporting assembly can be toggled to drive the cable body to deflect, and the U-shaped plate drives the ratchet to rotate, so as to adjust the angle of the cable body to ensure the verticality of the cable body in the overhead installation. After the angle adjustment of the cable body is completed, it is limited by the unidirectional rotation restriction of the ratchet and the ratchet, that is, the cable overhead supporting assembly cannot be reset in the opposite direction of the toggle rotation, so that the cable overhead supporting assembly carries the cable body to maintain the current angle, thereby improving the stability and integrity between the steel cable, the cable body and the cable overhead supporting assembly, and is not prone to fluctuations when dealing with high-altitude wind, which is conducive to ensuring the verticality of the overhead installation of the cable body, and reducing the surface wear of the cable body caused by insufficient stability, solving the problem that the connection stability and integrity between the traditional connection structure and the steel cable and the cable are insufficient, which is easy to cause cable fluctuations, thereby affecting the verticality of the cable, and also causing wear between the cable and the connection mechanism.
[0017] 2. The utility model also designs a limit groove and a limit ball. By rotating the knob, the semicircular block can be driven to deflect, so that the limit ball slides and engages in an adjacent limit groove, and an adjacent ratchet and ratchet wheel are engaged, thereby changing the unidirectional rotation limit direction of the ratchet and the ratchet wheel, which is easy to perform reverse adjustment during the verticality adjustment process of the cable body and reverse restriction at the same time.
