Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to a pressure gauge with a mechanical alarm whistle function. Background Technology

[0002] In many high-risk industries such as firefighting, chemical engineering, and mining, self-contained breathing apparatus (SCBA) is one of the key pieces of equipment for ensuring the safety of workers. The pressure gauge in the SCBA is crucial for users to monitor the pressure inside the cylinder in real time. Currently, the mechanical pressure gauges used in SCBA have certain limitations. Traditional mechanical pressure gauges only display the pressure value through the pointer's indication on the dial. In actual use, workers often need to concentrate on observing the pressure gauge, which can distract them from other potential hazards in complex and dangerous working environments. Moreover, when the pressure inside the cylinder drops to a dangerous level, the mechanical pressure gauge can only alert the user by the pointer approaching or reaching the warning area on the dial. However, this method of alerting is not conspicuous or direct enough, especially in low light, noisy environments, or when the user's attention is highly focused on the task at hand. It is easily overlooked, leading to the user being unable to change the cylinder or evacuate the dangerous environment in time, posing a significant safety hazard.

[0003] Electronic pressure gauges offer advantages such as accurate data transmission, remote data transmission capabilities, and intelligent alarm functions. However, completely abandoning the existing mechanical pressure gauge structure and adopting a completely new electronic pressure gauge for breathing apparatus presents several challenges. First, it requires significant modifications to the overall structure of the breathing apparatus, resulting in higher costs. Second, due to the long-term use of breathing apparatus in certain special environments, electronic equipment may be affected by external factors (such as strong impacts and electromagnetic interference), and its reliability may be lower than that of mechanical structures in some cases.

[0004] Therefore, many frontline rescuers often carry both mechanical and electronic pressure gauges. However, this makes the rescue operation inconvenient. For example, they might want to find the mechanical gauge but end up holding the electronic one; or they might need to check the readings of both gauges simultaneously to improve measurement accuracy, which requires searching for both pressure gauges they are carrying.

[0005] However, if a new pressure gauge that integrates both mechanical and electronic functions is purchased, the cost will increase, and the still usable mechanical pressure gauge will be replaced, resulting in a waste of equipment. Utility Model Content

[0006] This utility model provides a pressure gauge with a mechanical alarm whistle function. It can directly add an electronic pressure gauge and a mechanical alarm whistle to a mechanical pressure gauge to form a whole, which makes it convenient for users to observe the readings of the two pressure gauges at the same time, while the original mechanical pressure gauge can still be used normally, thus saving costs.

[0007] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0008] The top of the electronic pressure gauge (2) is equipped with a mounting connector (2-5), which is connected to the mechanical pressure gauge (1). The bottom of the electronic pressure gauge (2) is connected to the high-pressure pipe (4), and a mechanical alarm whistle (3) is installed on the side of the bottom of the electronic pressure gauge (2) near the high-pressure pipe (4). The front of the electronic pressure gauge (2) has a display screen mounting port for installing the electronic pressure gauge display screen (2-1). The air pressure in the high-pressure pipe (4) exceeds 30 MPa.

[0009] Currently, many air-breathing devices are equipped with mechanical gauges. If electronic equipment is to be added, it usually needs to be carried separately. However, the electronic part of the pressure gauge with mechanical alarm whistle function provided in this embodiment can directly add an electronic pressure gauge and a mechanical alarm whistle to the mechanical pressure gauge to form a whole. This allows the user to observe the readings of both pressure gauges at the same time, while the original mechanical pressure gauge still works normally, saving costs. Attached Figure Description

[0020] The electronic pressure gauge (2) has a mounting connector (2-5) at its top, which connects to the mechanical pressure gauge (1). The mechanical pressure gauge (1) can be a readily available mechanical pressure gauge device, such as... Figure 5The mechanical pressure gauges commonly found on the market are shown below. These mechanical pressure gauges (1) are usually installed in high-pressure gas pipelines, gas cylinder valves, or external gas source interfaces via mechanical gauge mounting connectors 1-3 during use. In actual operation, the mechanical pressure gauge (1) can be unscrewed from the mechanical gauge mounting connectors 1-3 and then installed at the mounting connectors 2-5 of the electronic pressure gauge 2.

[0021] The bottom end of the electronic pressure gauge (2) is connected to the high-pressure pipe (4), and a mechanical alarm whistle (3) is installed on the side of the bottom end of the electronic pressure gauge (2) near the high-pressure pipe (4); a display screen mounting port is provided on the front of the electronic pressure gauge (2) for installing the electronic pressure gauge display screen (2-1). In use, gas is input into the electronic pressure gauge (2) from the high-pressure pipe (4), and then input into the mechanical pressure gauge (1) through the mounting connector (2-5).

[0022] Inside the electronic pressure gauge (2), one end of the high-pressure tube (4) passes through the outer shell of the electronic pressure gauge (2) and extends out of the top of the electronic pressure gauge (2), and a mounting connector (2-5) is fixedly connected to the extended part; the other end of the high-pressure tube (4) is equipped with a high-pressure input port, and the other end of the high-pressure tube (4) is connected to the pressure reducer on the gas cylinder.
