Description

Technical Field

[0001] The utility model relates to the technical field of power protection, and in particular to a warning ball device for preventing birds from accidentally hitting a power transmission line and an installation device. Background Art

[0002] Recently, there have been frequent incidents of birds accidentally colliding with power transmission lines, causing casualties among rare birds. This has attracted great attention from relevant departments, which have called for research on rare birds accidentally colliding with power transmission lines and the development of corresponding technical products to reduce accidents involving rare birds accidentally colliding with power transmission lines.

[0003] Overhead transmission lines are thinner in diameter. For example, the diameter of the ground wire of an ultra-high voltage line is usually only about 1-2 cm. In addition, the ground wire is usually silvery white, which is difficult for birds to detect against the sky. At a certain flying speed, birds will accidentally hit the wires because they cannot identify the position of the wires in advance, resulting in casualties. In order to prevent birds from accidentally hitting the lines, bird repellent devices are usually installed on the wires to prevent birds from accidentally hitting the lines. The technical principle is: by installing a conspicuous bird repellent device on the line, birds can detect the existence of the line in advance during flight and then avoid the line.

[0004] In foreign countries, spirals are installed to form eye-catching markers on the line, but the grip of the spiral is relatively small. Under the action of long-term wind vibration, the spiral will slip on the line. Compared with spirals, some lines are installed with aviation warning balls. The warning balls are larger in size and eye-catching in color. After the warning balls are installed at certain intervals on the entire line, the line is well marked. In addition, bird-proof blades are installed on the line to warn flying birds. The blade is a large baffle that is fixed to the line by a clamp. It is divided into two types: rotatable and fixed. These bird-proof devices all need to be installed manually. On foreign lines with lower voltage levels, the line height is relatively low and the installation is relatively convenient. However, the height of domestic high-voltage lines is generally more than ten meters to tens of meters, and manual installation is time-consuming and laborious. In addition, according to the habits of birds, the devices are mostly installed on overhead ground wires. The bearing capacity of the ground wire is relatively low, and the safety of the manual installation process is difficult to guarantee. At the same time, aviation warning balls are dedicated to the aviation field, and the particularity of the power industry is not taken into account. The aviation warning ball has a bearing seat and is fixed with bolts and wires. The installation process is cumbersome. Utility Model Content

[0072] Embodiment 1:

[0073] A warning ball device for preventing birds from accidentally hitting a transmission line, such as Figure 1 and Figure 2 As shown, it includes: a hollow shell 1, an elastic mechanism and a supporting mechanism; the hollow shell 1 includes a first part 2 and a second part 3, the first part 2 and the second part 3 have a connection point, and the first part 2 and the second part 3 are opened and closed around the connection point; the elastic mechanism and the supporting mechanism are fixed in the hollow interior of the first part 2 and the second part 3; the elastic mechanism is close to the connection point, and the supporting mechanism is far away from the connection point; the original length of the elastic mechanism is smaller than the internal dimension length of the hollow shell 1; the spacing length between the two ends of the supporting mechanism in the open state is greater than the spacing length between the two ends of the supporting mechanism in the closed state; the first part 2 and the second part 3 are enclosed by a through hole for passing a wire; when the wire enters the through hole, the supporting mechanism is cut off by the wire under the gravity of the warning ball device, and the first part 2 and the second part 3 are closed under the action of the elastic structure. In this embodiment, the surface of the shell 1 is streamlined. Specifically, the shell 11 is a spherical hollow shell 11 structure, so as to buffer the impact of wind during use.

[0074] The first part 2 and the second part 3 are both cavities with openings, and the openings of the first part 2 and the openings of the second part 3 are arranged opposite to each other; the connection point is a hinge point, which is located on the same side of the openings of the first part 2 and the openings of the second part 3; in this embodiment, the shell 1 is composed of two hemispherical arc shells 1 of the same size, and the openings of the two hemispherical arc shells 1 are arranged opposite to each other, the top is connected by a movable hinge, and the lower end is an opening. In order to enable the opening of the shell 1 to be always on the lower side of the structure during the installation process, the center of gravity of the warning ball device is located on the side of the warning ball device away from the connection point, that is, the center of gravity of the warning ball device is located on its own lower side.

[0075] For the convenience of description, the two hemispherical arc-shaped shells 1 are called the first part 2 and the second part 3. The actual device can be horizontally rotated 180° in space, and its left and right orientation changes do not affect the description here.

[0076] The opening of the first part 2 and the opening of the second part 3 are both provided with a threading groove 4; the threading groove 4 encloses a through hole. In this embodiment, the threading groove 4 is provided in the middle of the opening end surface of the first part 2 and the middle of the opening end surface of the second part 3.

[0077] When the opening is in a closed state, the through hole formed by the threading groove 4 of the first part 2 and the threading groove 4 of the second part 3 is sleeved on the wire. The threading groove 4 is arranged in the middle of the first part 2 and the middle of the second part 3. In this embodiment, the length of the threading groove 4 is equal to the diameter length of the shell 1, and the threading groove 4 is a C-shaped groove, that is, an arc with a central angle corresponding to 180°. It is fixedly connected to both the first part 2 and the second part 3, and the opening direction of the threading groove 4 is the same as the opening direction of the first part 2 and the second part 3. When the first part 2 and the second part 3 are in a closed state, the two threading grooves 4 constitute a complete through hole, and the inner diameter of the through hole is greater than the outer diameter of the wire.

[0078] In order to increase the clamping force of the housing 1 to clamp the wire and prevent the warning ball device from slipping on the wire, a soft pad is installed in the wire threading groove 4, and a protrusion is provided on the soft pad; a mounting hole is opened on the side wall of the wire threading groove 4; the protrusion is adapted to the mounting hole, and the protrusion is installed in the mounting hole. In this embodiment, the soft pad is a rubber gasket, which increases the friction between the wire threading groove 4 and the wire, and increases the stiffness of the tension spring 5 inside the housing 1 to prevent the housing 1 from slipping on the wire.

[0079] like Figure 3As shown, the elastic mechanism includes a tension spring 5 and a spring mounting seat 6 respectively arranged on the inner side walls of the first part 2 and the second part 3; the tension spring 5 is always kept in a stretched state; the ends of the tension spring 5 are respectively installed in the spring mounting seat 6. In this embodiment, two spring supports are respectively installed in the upper half of the first part 2 and the second part 3, and the two ends of the tension spring 5 are respectively connected to the spring supports inside the first part 2 and the second part 3. When the first part 2 and the second part 3 are in a closed state, the internal tension spring 5 has a continuous clamping effect on the wire under tension.

[0080] The support mechanism includes a pin seat 7, an ejector pin 8 and an ejector pin support seat 9; the pin seat 7 is installed in the first part 2; the ejector pin support seat 9 is installed in the second part 3; one end of the ejector pin 8 is hinged on the pin seat 7, and the other end is detachably abutted in the ejector pin support seat 9; when the first part 2 and the second part 3 are converted from an open state to a closed state, the end of the ejector pin 8 is separated from the ejector pin support seat 9 and rotates toward the elastic mechanism. In order to facilitate the abutment of the wire with the ejector pin 8 and the rotation of the ejector pin 8, the side wall of the ejector pin 8 away from the connection point is located in the through hole, or between the end of the housing 1 away from the connection point and the through hole. The length of the ejector pin 8 is greater than the spacing length between the pin seat 7 and the ejector pin support seat 9 in the closed state. An avoidance groove is provided on the threading hole along the height direction; when the first part 2 and the second part 3 are in an open state, the end of the ejector 8 away from the pin seat 7 abuts against the ejector support seat 9, and the lower surface of the ejector 8 is located in the hole formed by the two threading grooves 4; when the first part 2 and the second part 3 are in a closed state, the end of the ejector 8 away from the pin seat 7 is separated from the ejector support seat 9, and the distance between the pin seat 7 and the ejector support seat 9 is less than the length of the ejector 8. The position of the pin seat 7 is higher than that of the ejector support seat 9, and it can be seen that there is a receiving groove on the ejector support seat 9 to receive the end of the ejector 8, and because the lower surface of the ejector 8 is in the hole formed by the two threading grooves 4. Specifically, the first part 2 is provided with a rotatable pin seat 7, which is connected to a ejector pin 8. An ejector pin support seat 9 is installed at a lower symmetrical position of the second part 3. When the first part 2 and the second part 3 are to be installed, the ejector pin 8 is separated, and the ejector pin 8 rotates clockwise under the action of gravity. The end of the ejector pin 8 away from the pin seat 7 falls on the ejector pin 8 support, thereby forming a supporting effect, so that the first part 2 and the second part 3 form an angle, so that the opening remains in an open state.

[0081] In order to prevent the opening from closing due to accidental contact when the opening is open, the support mechanism also includes a torsion spring; the torsion spring is deformed in the direction opposite to the rotation direction of the ejector pin 8, and the elastic force of the torsion spring is less than the gravity of the warning ball device; the pin seat 7 and the ejector pin 8 are connected by a torsion spring and a pin shaft.

[0082] In order to facilitate the separation of the ejector pin 8 and the ejector pin support seat 9, lubricating oil is applied between the ejector pin 8 and the ejector pin support seat 9.

[0083] The surface of the housing 1 is provided with a warning mark with a striking color. The warning mark includes a paint with a striking color and / or a luminous material. The warning mark is coated on the outer surface of the housing 1. The paint can be bright yellow, bright orange, or bright red, so that birds can find the warning ball in advance at a long distance. The warning mark can also be coated with a luminous material. At dawn and dusk, the luminous material emits light to effectively remind birds flying during this period.

[0084] The warning ball can be made of environmentally friendly materials that are resistant to high and low temperatures and ultraviolet rays, such as polyethylene PE material, to adapt to plateaus, tropical areas and other regions, to adapt to the protection of different birds in various regions.

[0085] The warning ball provided in this embodiment is composed of left and right hemispheres that can be opened and closed. The hemispheres are connected by a movable rotating pin. A high-rigidity tension spring 5 is arranged inside to tighten the left and right hemispheres in the closed state, clamping the wire without slipping. A thimble 8 is arranged inside the warning ball. When the opening is opened, the thimble 8 falls to the thimble support seat 9 to support the left and right hemispheres. When installing the warning ball, the opening is facing downward. The warning ball falls on the wire under the action of gravity. The thimble 8 touches the wire to form a toggle effect. The thimble 8 leaves the top position, and the tension spring 5 tightens the warning ball through its own elastic tension to complete the installation process.
