Description

Cluster umbrella open bird thorn

technical field

The utility model relates to an anti-bird thorn, in particular to an open-type anti-bird thorn of a cluster umbrella.

Background technique

In recent years, with the gradual improvement of the ecological environment, the number of breeding birds has gradually increased, and the range of activities has also expanded. Birds in some areas often build their nests on the towers of transmission lines. At the same time, birds excrete feces when they move on the towers. These activities are very likely to cause accidents on transmission lines, and often cause single-phase grounding short circuits on transmission lines. Cause the insulation performance of the insulator to decline, and then cause the tripping fault, that is, the bird damage of the transmission line. At present, bird damage accidents on transmission lines have become another major hidden danger affecting the safe operation of transmission lines after lightning activities and external force damage.

In order to improve the reliability of the transmission line operation of the power system and avoid tripping accidents on the transmission line due to bird activities, the power systems in the country mainly use common anti-bird thorns to prevent birds. The existing anti-bird thorns are mainly installed and fixed above the hanging points of the insulator strings of electric poles and towers through gaskets, and the anti-bird thorns are distributed in a scattered manner, which is not only difficult to install, but also increases the labor intensity of maintenance workers, and is not conducive to maintenance workers Carry out maintenance and downlink operations.

Contents of the invention

The technical problem to be solved by the utility model is to provide an open-type anti-bird thorn cluster umbrella that is convenient for installation and maintenance workers to perform maintenance and unloading operations, and can reduce the labor intensity of maintenance workers.

In order to solve the above problems, the utility model adopts the following technical solutions:

A cluster umbrella open-type anti-bird thorn, including a fixed bracket, a fixed top wire is connected under the fixed bracket, and acupuncture is provided above the fixed bracket. The special feature is: a support is fixed on the fixed bracket A telescopic sleeve is hinged on the support by bolts. The acupuncture is located in the expanded telescopic sleeve. The expanded length of the telescopic sleeve is equal to the length of the acupuncture. The acupuncture chassis is hinged on the The lower end cover of the telescopic sleeve on the support is fixed in the lower port of the telescopic sleeve.

As a further preference, the fixing bracket is U-shaped.

As a further preference, the lower end cover of the telescopic sleeve is T-shaped, the lower end is inserted into the support, and the upper end is screwed to the lowermost segment of the telescopic sleeve.

As a further preference, the bolts are locked through wing nuts after passing through the support.

As a further preference, the telescopic sleeve can be turned over 180 degrees on the support with the bolt as the axis.

The beneficial effects of the utility model are: since the telescopic casing is hinged with bolts on the support above the fixed bracket, the acupuncture is located in the telescopic casing, so the telescopic casing can be unfolded during installation and maintenance to make the needle The thorns are completely inserted into the telescopic casing, which is not only convenient for installation, but also convenient for maintenance workers to perform maintenance and stringing operations, and can reduce the labor intensity of maintenance workers.

detailed description

As shown in Figures 1 and 2, the utility model relates to a cluster umbrella open-type anti-bird thorn, including a fixing bracket 2 for fixing on the pole cross-arm angle iron, the fixing bracket 2 is U Shaped and arranged horizontally, a fixed top wire 1 is threadedly connected below the fixed bracket 2, and the upper end of the fixed top wire 1 is screwed into the fixed bracket 2.

Acupuncture 6 is arranged above the fixed bracket 2, a support 3 is welded on the fixed bracket 2, and a telescopic sleeve 5 is hinged on the support 3 through a bolt 8, and the telescopic sleeve 5 is composed of a multi-section sleeve The lower end of the telescopic sleeve 5 is provided with a lower end cover 4, and the acupuncture 6 is located in the expanded telescopic sleeve 5, and the length of the expanded telescopic sleeve 5 is the same as the length of the acupuncture 6. Equal, the chassis of acupuncture 6 is fixed in the lower port of telescopic sleeve 5 by the lower end cover 4 of telescopic sleeve 5 hinged on support 3. The lower end cover 4 of the telescopic sleeve 5 is T-shaped and the lower end is inserted into the support 3, and the upper end is screwed to the bottom section of the telescopic sleeve 5. The telescopic sleeve 5 is mounted on the support 3 with Bolt 8 can turn over 180 degrees for the axle.

Preferably, the bolt 8 is locked through the wing nut 7 after passing through the support 3 and the lower end cover 4 .

During installation, the telescopic sleeve 5 is fully unfolded and the acupuncture 6 is covered inside, the fixed bracket 2 is fixed on the pole cross-arm angle iron through the fixed top wire, and the telescopic sleeve 5 is rotated to make it in a vertical state. Tighten the wing nut to keep the telescoping sleeve 5 in a vertical state, retract the telescoping sleeve 5, and make the exposed acupuncture 6 disperse completely.

Although the embodiment of the present utility model has been disclosed as above, it is not limited to the use listed in the description and the implementation, and it can be applied to various fields suitable for the present utility model.
