Problems solved by technology

The deicing rod of the existing hammering type deicing device adopts a solid structure. When deicing, the whole deicing device moves forward on the overhead ground line, and the driving device intermittently drives the deicing rod to hammer the ice-coated transmission line. The device cannot effectively remove the ice between the first hammer point and the next hammer point, and the deicing effect is not good

Embodiment 1

[0020] A kind of deicing stick used for deicing device of ice-coated line of the present invention, such as Figure 8 As shown, the deicing stick 63 is a hollow structure, and a spring 153 is arranged in the length direction inside it. Ball 154, in order to ensure the interaction range and sufficient quality of the counterweight balls, the diameter of the deicing stick 63 is greater than the diameter of the connecting rod 91, therefore, in order to ensure the effective connection with the connecting rod 91, between the deicing stick 63 and the threaded section 151 A transition section 152 is provided, and the outer diameter of the transition section 152 is less than or equal to the distance between the two connecting plates on the connecting part of the connecting rod 91, so as to ensure that the threaded section of the deicing stick can be effectively connected with the threaded hole of the connecting rod. When performing deicing operations, the deicing stick can be installed...

Embodiment 2

[0023] When the length of the deicing stick 63 is not enough to hammer the icing transmission line, in order to adjust the distance between the deicing stick 63 and the icing transmission line, to ensure that each hammering can act on the icing transmission line, such as figure 2 , 3 As shown, at least two connecting rods 91 are connected to the deicing stick 63, and at least two connecting rods are connected to each other at the ends. Drive the connecting rod 91 to drive the deicing stick 63 to hammer the ice-coated transmission line, such as Figure 4 , 5 As shown, the hinged connection between adjacent connecting rods 91, such as Figure 7 As shown, the deicing stick 63 is threadedly connected with the connecting rod 91. Specifically, the bottom of the connecting rod 91 is provided with a threaded hole 131, and one end of the deicing stick is provided with a threaded section 151, and the threaded section 151 is mated with the threaded hole 131. The connection facilitate...

Embodiment 3

[0027] In order to ensure that when the deicing stick is lifted by the driving device, all the connecting rods connected to it will not move in the opposite direction, and all the connecting rods can only swing in the same direction, as shown in 4-6, when the connecting rods are connected One of the sides adjacent to the connecting plate is provided with a baffle 111, and after being connected with the adjacent connecting rod 91, the bottom end of the baffle 111 is located between the rotating shaft of the adjacent connecting rod and the top end 121 of the connecting block, where The "bottom end of the baffle" refers to the end of the baffle near the hole of the rotating shaft. During installation, one side of the baffle plate of the deicing stick is installed close to the icing transmission line, and the baffle can limit the swing of the connecting rod to the direction close to the icing transmission line, so as to ensure that the deicing stick is lifted to the required height...

Abstract

The invention discloses a deicing stick used for a deicing device of an ice-covered line. The deicing stick is a hollow structure, and a spring is arranged in the length direction of the inside thereof, and counterweight balls are equidistantly arranged on the spring. After completing the hammering action of the first hammering point, the side wall of the deicing stick rebounds under the reaction force. At this time, the counterweight ball in the deicing stick still moves to this side wall of the deicing stick due to inertia, And hit the inner wall of the deicing stick, so that the deicing stick hammers the ice-covered power transmission line again. During this process, the spring is stretched to generate a certain elastic force, and the counterweight ball is pulled back to the deicing stick under the action of the spring force. The other side wall hits again, and the counterweight ball moves to the direction close to the ice-coated transmission line after being hit, until it hits the side wall of the deicing stick to hammer the ice-coated power line, and so on, until the deicing stick hits the next hammer It can effectively break the ice between two hammering points, so as to improve the overall deicing effect.

Description

technical field [0001] The invention relates to a deicing device, in particular to a deicing stick used in a deicing device for ice-covered lines. Background technique [0002] Icing on transmission lines will cause damage to transmission lines to varying degrees, resulting in a large number of power outages. In order to avoid the occurrence of accidents, the power transmission line must be deiced. At present, the methods of deicing mainly include artificial deicing, mechanical deicing, direct current melting, etc. Among them, the best deicing effect is direct current melting. However, due to the immature technology and huge investment costs, some remote areas The DC deicing technology cannot be used, therefore, the practical application is mainly based on manual deicing. [0003] There are two main types of manual deicing, that is, rope pulling ice and stick vibration deicing. Rope pulling ice mainly means that people pull the rope under the wire to remove the ice on the ...
