Description

Technical Field

[0001] The utility model relates to the technical field of power protection, and particularly relates to an overhead transmission line installation clamp and an installation device. Background Art

[0002] In recent years, several incidents have occurred in some areas where rare wild birds such as black-necked cranes accidentally hit transmission lines, resulting in casualties of rare birds such as black-necked cranes, swans, and grey cranes, which has attracted the high attention of relevant departments.

[0003] In order to protect rare birds from being accidentally hit and injured or killed by transmission lines, relevant units have carried out research on anti-bird collision devices, specifically, some research and applications of bird protection warning balls, that is, using warning balls used in aviation and installing them on overhead transmission lines to achieve the effect of reminding flying birds of the existence of overhead lines.

[0004] Currently, most warning balls are installed manually. In the case of power outage, power workers climb onto the line and install the warning balls they carry with them on the overhead line. Due to the development of aviation capabilities, some power institutions have installed supports on helicopters, and the installation personnel approach the overhead line on the support and install the warning balls on the line.

[0005] However, when installing warning balls manually, power outage operations are required. Reporting a power outage plan is needed for line power outage. Constrained by various factors, it is often difficult to install warning balls in a timely manner, and the installation efficiency is low. At the same time, the installation cost and risk of warning balls are relatively high, and the risk for operators to climb the tower and walk on the line is great.

[0006] There is also a method of installing a spiral. An anti-bird collision spiral is installed on the overhead line to remind flying birds of the position of the overhead line and enable them to avoid it in advance, thereby preventing flying birds from accidentally hitting the line.

[0007] However, installing the spiral requires operators to install it by helicopter, which is very costly, poses a great technical challenge to the pilots, and the distance between the propeller blades and the overhead line needs to be strictly controlled. Otherwise, accidents such as plane crashes and deaths will occur, and the installation efficiency is low. The method of installing the spiral also requires power outage operations, and the installation process is also relatively risky. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0071] In order to better understand the utility model, the content of the utility model will be further described below in conjunction with the specification drawings and examples.

[0072] The present application provides an installation fixture for an overhead transmission line. When the upper ends of the first clamping arm and the second clamping arm are separated, the wire enters between the first clamping arm and the second clamping arm above the installation fixture. The wire is crimped on the upper side of the support mechanism and applies a downward pressure to the support mechanism, causing the state between the end of the support mechanism and the second clamping arm to change from being tightly abutted to being separated. And through the elastic tension provided by the elastic mechanism, the two openings are gathered together to form a through hole, so that the wire is threaded through the through hole, realizing the automatic installation of the installation fixture on the wire. The installation process is simple, with low cost and low risk.

[0073] Embodiment 1:

[0074] An installation fixture for an overhead transmission line, as Figure 1 shown, includes: an elastic mechanism, a support mechanism, and a first clamping arm 1 and a second clamping arm 2; the lower ends of the first clamping arm 1 and the second clamping arm 2 are rotatably connected, and both upper ends thereof have openings; the openings of the first clamping arm 1 and the second clamping arm 2 are arranged oppositely; both ends of the elastic mechanism are respectively installed on the lower halves of the first clamping arm 1 and the second clamping arm 2, and the elastic mechanism always remains in a stretched state; a hinge portion is provided on the first clamping arm 1; a contact portion is provided on the second clamping arm 2; one end of the support mechanism is rotatably connected to the hinge portion, and the other end is tightly abutted or separated from the contact portion; when the support mechanism is tightly abutted to the contact portion, a part of the upper surface of the support mechanism is located within the opening; when the support mechanism is separated from the contact portion, the openings of the first clamping arm 1 and the second clamping arm 2 enclose to form a through hole for threading the wire, and the support mechanism is separated from the through hole. The opening is in a C shape 3; the lower halves of the first clamping arm 1 and the second clamping arm 2 are in an "|" shape and are arranged vertically; the "|" shape is installed at the opening of the C shape 3; both ends of the elastic mechanism are respectively installed on the upper halves of the two "|" shapes; the hinge portion is provided within the C shape 3 of the first clamping arm 1; the contact portion is provided within the C shape 3 of the second clamping arm 2.

[0075] In this embodiment, there is an opening between the first clamping arm 1 and the second clamping arm 2, and the two "|" shapes rotate relative to each other.

And this device is installed on the wire by the upward movement of the aircraft. Therefore, the opening is located on the upper side of the installation fixture. When the wire enters the opening, the wire contacts the upper surface of the support mechanism, causing the support mechanism to separate from the contact portion and rotate downward.

To prevent the plate buckle 5 from rotating due to gravity, a torsion spring is provided between the plate buckle 5 and the hinge shaft. The torsion spring provides an elastic force in the counterclockwise direction, and the elastic force provided by the torsion spring is greater than the weight of the plate buckle 5.

[0080] As Figure 3 shown, the abutting part is a receiving groove; the opening of the receiving groove faces the first clamping arm 1; the end of the plate buckle 5 far from the first clamping arm 1 is received in the receiving groove and abuts tightly against the bottom wall of the receiving groove. In this embodiment, the axis of the receiving groove is perpendicular to the rotation axis of the support plate.

[0081] As Figure 4As shown in the figure, the plate buckle 5 includes a narrow handle 6 and a wide handle 7 which are fixedly connected; the narrow handle 6 is located above the wide handle 7; a part of the upper surface of the narrow handle 6 is located within the U-shaped part 3; the end of the wide handle 7 away from the second clamping arm 2 is hinged within the avoidance hole 10; the end of the wide handle 7 away from the first clamping arm 1 abuts against the bottom wall of the accommodation groove. The wide handle 7 and the narrow handle 6 form an angle; the angle is an acute angle, and the opening of the angle faces the second clamping arm 2. In this embodiment, the plate buckle 5 includes a narrow handle 6 and a wide handle 7 which are fixedly connected; the wide handle 7 is located below the narrow handle 6, and the wide handle 7 and the narrow handle 6 form an angle; the connection end of the wide handle 7 and the narrow handle 6 is located on the side of the narrow handle 6 facing the first clamping arm 1; the wide handle 7 is hinged to the first clamping arm 1; the narrow handle 6 is separated from the second clamping arm 2, and the end of the narrow handle 6 away from the first clamping arm 1 is located within the through hole; when the opening is in the open state, the end of the narrow handle 6 abuts against the second clamping arm 2. In order to increase the structural strength of the plate buckle 5, a reinforcing rod is installed on the side of the wide handle 7 close to the second clamping arm 2, and the other end of the reinforcing rod is fixedly connected to the narrow handle 6.

[0082] The accommodation groove includes a narrow through hole 8 and a wide groove 9; the wide groove 9 is formed on the "|" shape of the second clamping arm 2; the narrow through hole 8 is formed on the U-shaped part 3 of the second clamping arm 2; the narrow through hole 8 communicates with the wide groove 9; the inner width of the narrow through hole 8 is greater than the width of the narrow handle 6 and less than the width of the wide handle 7; the narrow through hole 8 is located on the rotation path of the narrow handle 6; the inner width of the wide groove 9 is greater than the width of the wide handle 7; the wide handle 7 abuts against the bottom wall of the wide groove 9.

[0083] The distance between the abutting position of the wide handle 7 and the wide groove 9 and the lower end of the "|" shape is greater than the distance between the hinge axis and the lower end of the "|" shape. In this embodiment, in order to prevent the plate buckle 5 from rotating and releasing the abutting state, the abutting position of the wide handle 7 and the wide groove 9 is higher than the position of the hinge axis.

[0084] In this embodiment, the accommodation groove includes a narrow through hole 8 and a wide groove 9 arranged from top to bottom; the narrow through hole 8 is located in the middle of the top wall of the wide groove 9, and the narrow through hole 8 communicates with the wide groove 9; the wide handle 7 abuts against the top wall of the wide groove 9, and the inner width of the wide groove 9 is greater than the width of the wide handle 7; the end of the narrow handle 6 away from the first clamping arm 1 passes through the narrow through hole 8, and the inner width of the narrow through hole 8 is greater than the width of the narrow handle 6 and less than the width of the wide handle 7.

In order to prevent the plate buckle 5 from rotating by itself due to gravity, the position of the top wall of the wide groove 9 is higher than the hinge position of the wide handle 7 and the first clamping arm 1, and the elastic force provided by the tension spring 4 can prevent the plate buckle 5 from rotating clockwise by itself. Similarly, in order to prevent the plate buckle 5 from rotating by itself due to gravity, a torsion spring is also arranged between the wide handle 7 and the hinge axis; the torsion spring rotates in the counterclockwise direction. In this embodiment, the elastic force provided by the torsion spring is less than the elastic force provided by the tension spring 4.

To increase the clamping force between the semi-circular groove and the wire, a soft pad is installed in the semi-circular groove. A soft pad is installed inside the annular structure. A gasket mounting hole is provided on the circumferential side wall of the annular structure; a gasket mounting protrusion is provided on the soft pad; the gasket mounting protrusion is installed in the gasket mounting hole by interference fit, increasing the friction between the fixture and the overhead line and preventing the fixture from slipping along the line.

The encircling portion is used to tightly hold the wire, and a rubber gasket can be installed inside to increase the friction between the fixture and the wire and prevent the fixture from slipping along the wire. The pivot pin mounting hole portions of the first clamping arm 1 and the second clamping arm 2 are arranged in a staggered form to facilitate the installation of the pivot pin, and the first clamping arm 1 and the second clamping arm 2 can rotate flexibly.

The width of the narrow through-hole 8 is greater than the width of the narrow handle 6 and less than the width of the wide handle 7, and the width of the wide groove 9 is greater than the width of the wide handle 7. When the trigger rotates, a limiting effect can be formed. The narrow handle 6 can rotate freely in the notch, while the wide handle 7 can only fall into the wide groove 9 and cannot rotate past the narrow through-hole 8. The elastic pin mounting portion is provided with an elastic pin hole. When installing, an elastic pin is inserted, and a hole is left at the end of the elastic pin to connect the tension spring 4.

During installation, the drone carries the mounting fixture with the opening facing upward and aligns it with the wire so that the wire can enter between the first clamp arm 1 and the second clamp arm 2 from the opening. As the drone continues to ascend, the mounting fixture also moves upward synchronously, so that the wire is crimped to the narrow handle 6. After being subjected to pressure, the narrow handle 6 begins to rotate clockwise until the opening is closed and the first clamp arm 1 and the second clamp arm 2 hold the wire tightly.
