Description

  The present invention relates to a bird repellent dispensing gun for an indirect hot line method that uses an indirect hot wire tool to pour a bird repellent from the tip of a cylindrical cartridge enclosing a bird repellent.

  There are many bird damage accidents caused by crows, pigeons and other birds, particularly crows, on power pole braces and power transmission towers. For example, a crow sometimes uses a metal material such as a hanger to make a nest in a power brace or a power transmission tower. If a metal material such as a hanger touches an electric wire or power transmission line, it can cause a wide range of power outages.

  Conventionally, in order to prevent this bird damage, there has been proposed one in which a jig having a special shape is attached to a utility pole or a steel tower. However, since these structures are fixed, the effects are not sustained by the familiarity of crows, and are not suitable for preventing bird damage over a long period of time.

  Therefore, components that birds repel physically or chemically are contained, and bird repellents have been gradually used (see Patent Document 1). By applying this bird repellent to the armrests of power poles, power transmission towers, etc. to prevent bird nesting, bird damage can be prevented for a long time.

  By the way, as an auxiliary tool for efficiently and easily dispensing the bird repellent, for example, as shown in FIG. 3, a cartridge C in which the bird repellent is sealed is attached to the cartridge holder 311, and the cartridge C Various caulking guns 301 have been proposed in which a bird repellent is dispensed from a nozzle C2 provided at the tip of a cartridge C by pressing a pressing plate C1 provided on the back of the cartridge C1 (see Patent Document 2).

  When applying a bird repellent to a utility pole armor or a power transmission tower using the caulking gun 301, the state of being energized in consideration of the influence of homes and factories around the work site, The operation is performed in a so-called live line state. The construction method performed in this live wire state is called the live wire construction method, using a straight live wire construction method in which an operator works while directly touching the electric wire part and an indirect live wire tool (auxiliary equipment) such as a so-called Yatsuko. There are two known methods of indirect hot-wire construction in which an operator works.

Here, in the case of the direct hot wire method, the operator wears rubber gloves for electric work and performs the work by directly gripping the caulking gun 301. Therefore, the metal part of the caulking gun 301 comes into contact with the electric wire to cause a short circuit. It may happen. Therefore, it is preferable that the operation of applying the bird repellent to the arm of the power pole, the power transmission tower, etc. using the caulking gun 301 is performed by an indirect hot wire method that is less likely to cause a short circuit.
