Embodiment 1

[0032] as attached Figure 2-4 As shown, a grounding solder warning device includes a protective cover 5 covered on the outer side of the grounding solder 1, a top plate 8 fixedly connected to the top of the protective cover 5, an infrared induction alarm 9 fixed on the top plate 8, and an infrared sensor alarm 9 fixed on the top plate. 8 fixed rods 12 in the middle and the rain cover 10 connected to the top of the fixed rods 12;

[0033] Infrared alarms are divided into active and passive. This device adopts an active infrared alarm. Specifically, the alarm actively emits infrared rays. When the infrared rays touch obstacles, they will bounce back and be received by the alarm probe. If the probe detects that the infrared rays are stationary, that is, the red line is continuously emitted and rebounded continuously, then the alarm will not alarm. When a moving object violates this invisible red line, the probe will detect an abnormality and call the police. Its working princ...

Embodiment 2

[0044] A grounding solder alarm, comprising a protective cover 5 covered on the outer side of the grounding solder 1, a top plate 8 fixedly connected to the top of the protective cover 5, an infrared induction alarm 9 fixed on the top plate 8, and a Fixed rod 12 and the rain cover 10 that is connected at the top of fixed rod 12;

[0045] Infrared alarms are divided into active and passive. This device adopts an active infrared alarm. Specifically, the alarm actively emits infrared rays. When the infrared rays touch obstacles, they will bounce back and be received by the alarm probe. If the probe detects that the infrared rays are stationary, that is, the red line is continuously emitted and rebounded continuously, then the alarm will not alarm. When a moving object violates this invisible red line, the probe will detect an abnormality and call the police. Its working principle is as follows: the main materials of the pyroelectric infrared sensor are lithium tantalate (LiTao3...

Abstract

The invention discloses a grounded drill rod warning device. The grounded drill rod warning device comprises a protective hood covering the outer side of a grounded drill rod, a top plate fixedly connected to the top of the protective hood, an infrared induction alerter fixedly arranged on the top plate, a fixed rod fixed to the middle of the top plate and a rain hood connected to the top end of the fixed rod, wherein the rain hood completely covers the infrared induction alerter. The grounded drill rod warning device is simple in structure, reasonable in design, low in production cost and suitable for operation on a power distribution construction site; the grounded drill rod warning device applied to the construction site completely covers the remaining part, exposed on the ground, of the grounded drill rod, and a red-and-white reflective sticker can play a warning role; when night light is insufficient and a pedestrian is close to the grounded drill rod, the infrared inductor can induct the situation in time and give an alarm to play the warning role, so that accidental hurt to the pedestrian is avoided.

Description

technical field [0001] The invention relates to the technical field of distribution network power equipment, in particular to a grounding solder warning device. Background technique [0002] In electric power construction and maintenance work, in order to ensure the safety of construction and maintenance, the installation of grounding wires is an essential and important work item. In the workplace where there is no way to borrow on-site grounding wires, most of them use local use. The ground solder is grounded. Most of the existing grounding drills are steel drills with a pointed tip at one end, which are inserted into the ground by tools such as hammers to insert them into the ground, and are pulled out after the construction is completed. The grounding rod is a long rod-shaped grounding device, one end of which is nailed into the ground, and the other end is connected to the grounding wire of the electrical equipment, so that the current can be smoothly introduced into th...
