Problems solved by technology

Although the power company has arranged personnel to carry out patrol inspections, but the lack of timeliness, it is still unable to achieve effective prevention
[0003] Excavator drivers often have low education levels, high work intensity, and tight working hours. During the construction process, they often forget the safety precautions and the safe distance that should be kept for near-electric construction operations, resulting in electrical safety accidents and damage to electrical equipment. caused economic loss
In terms of preventing damage caused by external forces (referred to as "anti-breakage"), there are not many effective prevention and control methods, mainly based on on-site personnel on duty, but limited by the quality of personnel on duty. Improvement, but still can not meet the requirements of on-site prevention and control

Embodiment 1

[0041] An embodiment of the invention provides an excavator and an operation alarm system thereof.

[0042] Such as figure 1 As shown, the excavator operation alarm system includes a metal detector 1 , a communication device 2 and an alarm 3 .

[0043] The metal detector 1 is installed on the shovel of the excavator. During the construction of the excavator, when the metal detector 1 detects underground metal, it sends an early warning signal to the alarm 3 through the communication device 2, and the alarm 3 receives the early warning signal. ,Alert.

[0044] In this embodiment, specifically, as figure 2 As shown, the communication device 2 includes a wireless transmitter 21 and a wireless receiver 22 . The wireless transmitter 21 is installed on the shovel of the excavator, and according to the information detected by the metal detector 1, the early warning signal is sent to the wireless receiver 22 through the wireless transmitter 21, and the wireless receiver 22 is inst...

Embodiment 2

[0056] This embodiment is a specific example of the construction of the excavator provided in the first embodiment above.

[0057] In this embodiment, power cables are laid underground at the construction site of the excavator. When the driver of the excavator enters the driver's cab and starts the excavator to prepare for construction, the reminder device plays the "Electric Power Law of the People's Republic of China", "State Grid Corporation of China" through the voice module. The safety precautions for excavator near-electricity work in the company's Electricity Safety Work Regulations and the "Regulations on the Protection of Electric Power Facilities" of the provinces and cities where the construction site is located strengthen the safety awareness of excavator drivers.

[0058] In addition, before the construction of the excavator, the input preset alarm distance is 2 meters, and the preset alarm distance is divided into 4 intervals through the interval unit of the frequ...

Abstract

The invention provides an excavator and a work alarm system thereof and relates to the electric power safety protection technology field. The excavator work alarm system comprises a metal detector, a communication device and an alarm device. When underground metal is detected by the metal detector mounted at a shovel portion of the excavator, an early warning signal is sent to the alarm device through the communication device, after the early warning signal is received by the alarm device, sound and light alarm is emitted, a technical problem that electric power cables are damaged by the excavator during construction work is solved, safety work consciousness of excavator drivers is improved, the technical effect of reducing electric power cable break accidents caused by excavator construction is realized, an electric power facility protection and propaganda mode is innovated, strong practicality and high reliability are realized, and the excavator work alarm system is applicable to the mechanical construction field.

Description

technical field [0001] The invention relates to the technical field of electric power safety protection, in particular to an excavator and an operation alarm system thereof. Background technique [0002] At present, with the steady development of China's economy, the rapid expansion of cities, more and more frequent urban and rural infrastructure construction, and more and more construction projects, the engineering team has to use large-scale machinery and equipment to speed up the process during the construction process. However, in some high-voltage environments, the operation of large-scale mechanical equipment is difficult. In addition, operators do not abide by construction specifications and neglect safety management, which often damages transmission lines and brings irreparable economic losses and social impacts. In recent years, high-voltage power cable digging accidents caused by excavator construction have occurred frequently, posing a huge threat to the safe oper...
