Description

Line tower bird repellent

technical field

The utility model relates to a bird repelling device, in particular to a bird repelling device for a line pole and tower.

Background technique

At present, the urban-rural junction is large, and large trees are scarce; the suburban industrial park has a large area, and there are many knife gates, cross-arms, poles and towers; it is suitable for nesting. Birds tend to build bird's nests at the crossarm of the knife gate of the lower pole tower, and the bird's nests are likely to cause short circuit of the line, which has seriously endangered the safe operation of the 10KV line. The frequent demolition of the Bird's Nest has caused a lot of workload and a huge amount of expenses to the electricity customers and the power supply company. Solving the problem of pole tower knife gate cross arm bird nesting can greatly reduce the probability of occurrence of bird damage. Especially the upper side of the middle phase knife gate is the key part of bird prevention.

However, the existing anti-bird measures are weak, most of the existing anti-bird measures are static, and the birds have strong adaptability, and can adapt to the static measures in a short period of time, so the static bird-repelling device cannot continue to play the role of bird-repelling; The color of the appearance of some existing anti-bird measures has no obvious bird-striking effect, and most of the existing measures fail to scientifically utilize the bird-striking effect of specific colors, and the bird-proofing effect is insufficient. Some bird-repelling devices have ideal bird-repelling effects, such as sound bird-repelling devices, but the cost is high, which is not conducive to popularization and use.

An existing simple bird repelling device basically solves the above-mentioned problems, and is composed of a wind rotating device and a connecting frame arranged below it; The main shaft is covered with a sleeve on the upper part of the main shaft, and a plurality of connecting rods are connected outside the sleeve, and each connecting rod is provided with a bowl-shaped wind cup. The wind blows the wind cup to drive the connecting rod and the sleeve to rotate together, thereby realizing the bird repelling function. But when it rains, rainwater easily enters between the sleeve and the main shaft. After a long time, it will cause rust and corrosion, affect the use effect of the bird repelling device, and have a short service life.

Utility model content

In order to overcome the disadvantages of the above-mentioned prior art, the purpose of this utility model is to provide a bird repelling device for a line pole tower, which has an ideal effect of repelling birds, and has a good rainproof effect and a long service life.

In order to solve the above-mentioned problems, the utility model adopts the following technical solutions: the line pole tower bird repellent includes a wind power rotating device and a connecting frame connected with the cross arm of the pole tower. A bowl-shaped wind cup, characterized in that: a sleeve is placed outside the main shaft and the main shaft and the sleeve can rotate relatively, the sleeve passes through an umbrella-shaped shield and is fixedly connected with the umbrella-shaped shield as a whole , the connecting frame is arranged at the bottom of the umbrella-shaped shield; the outer side of the upper part of the sleeve is provided with a cylindrical shield, the top of the main shaft is fixedly connected with the cylindrical shield, and the bowl-shaped wind cup is arranged on the connecting rod , the other end of the connecting rod is connected with the cylindrical protective cover.

As a further technical solution of the present utility model: an arc-shaped top cover is provided on the top surface of the cylindrical protective cover.

The main shaft is a stepped shaft, and the stepped part cooperates with the top end of the sleeve to form a longitudinal limiting mechanism of the main shaft.

A further technical solution: the outer surfaces of the wind rotating device, the umbrella-shaped shield, and the connecting frame are all painted red.

The beneficial effects of the utility model are: it prevents bird damage, ensures the safety of the power grid; ensures the reliability of power supply, increases the power supply; reduces the maintenance workload and cost; and has a simple structure and low cost, and is suitable for popularization and use.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the front view of the utility model embodiment,

Figure 2 is a top view of Figure 1,

In the figure: 1 connecting frame, 2 main shaft, 3 sleeve, 4 umbrella-shaped shield, 5 cylindrical shield, 6 bowl-shaped wind cup, 7 connecting rod, 8 arc-shaped top cover.

Detailed ways

As shown in Fig. 1 and Fig. 2, the line pole tower bird repellent mainly includes a wind power rotating device and a connecting frame 1 connected with the pole tower cross arm. The wind rotating device includes a main shaft 2, a sleeve 3 is placed outside the main shaft, and a gap is provided between the main shaft 2 and the inner wall of the sleeve 3 to ensure that the main shaft can rotate flexibly in the sleeve. The main shaft 2 is a stepped shaft, and its step cooperates with the top end of the sleeve 3 to form a longitudinal limiting mechanism of the main shaft 2 .

The sleeve 3 passes through an umbrella-shaped shield 4 and is integrally connected with the umbrella-shaped shield. The connecting frame 1 is connected to the bottom of the umbrella-shaped shield 4 by bolts. A cylindrical protective cover 5 is provided on the outside of the upper part of the sleeve 3, and the cylindrical protective cover 5 is fixedly connected with the top of the main shaft as a whole. The bowl-shaped wind cup 6 is arranged on the connecting rod 7 , and the other end of the connecting rod 7 is connected with the cylindrical protective cover 5 . Three bowl-shaped wind cups are evenly distributed around the main axis.

An arc-shaped top cover 8 is arranged on the top surface of the cylindrical protective cover 5 . It is not conducive to birds to build nests, so as to ensure the effect of repelling birds.

The outer surfaces of tubular protective cover 5, arc-shaped top cover 8, connecting rod 7, wind cup 6, umbrella-shaped shield 4, and connecting frame 1 are all painted red, and the effect of driving birds can be more ideal.

During installation and use, the connecting frame 1 is installed on the cross arm of the pole tower through the connecting piece. The bowl-shaped wind cup 6 is blown by the wind, and the cylindrical protective cover 5 and the main shaft 2 are driven to rotate together by the connecting rod 7 . Since the sleeve 3 and the main shaft 2 are completely covered by the cylindrical protective cover 5, it is ensured that rainwater will not flow into the space between the sleeve 3 and the main shaft 2 when it rains, thereby preventing rust caused by rainwater and prolonging the life of bird repelling. service life of the device.

As other embodiments, bearings can be installed between the sleeve 3 and the main shaft 2, and between the cylindrical protective cover 5 and the sleeve 3, so that the main shaft can rotate flexibly in the sleeve as well.
