Description

Gas fuel leakage monitor

Technical Field

The present utility model relates to a monitor, and more particularly to a gaseous fuel leak monitor.

Background

Most of the shells of the existing gas fuel leakage monitors are provided with air inlets on a plane, and users find that the following defects exist when the air inlets on the shells of the gas fuel leakage monitors are arranged on the plane in actual use:

The air inlet is arranged to be planar, and when the external air flows or the air pressure changes, the internal and external pressure difference can cause air or pollutants outside the air inlet to enter the inside of the monitor, so that false alarm or interference is caused.

Such that rain, water droplets, or other liquids accumulate at the air inlet, which may enter the interior of the monitor, causing the monitor to fail or otherwise degrade its performance.

Accordingly, there is a need for improved airflow routing of air intakes to minimize external disturbances and to minimize the impact of these problems by proper design and measures.

The utility model discloses a gas fuel leakage monitor. Has the following advantages:

1. Improving the airflow guiding mode: by employing a hump-type pod design, the flow path of the airflow is altered and creates drag and turbulence, slowing down the airflow when it contacts the hump, and this improved airflow direction helps to control the flow direction and velocity of the airflow, reducing the impact of external disturbances on the monitor.

2. Preventing liquid from entering: the hump-shaped bulge prevents liquid from directly entering the air inlet, the air flow is guided to a specific direction, the speed and the flow direction of the air flow are changed, the liquid is forced to flow away from the air inlet and is guided to a region far away from the air inlet, and the liquid cannot directly enter the air inlet but is guided to other directions by the air guide cover.

A gaseous fuel leakage monitor as shown in fig. 1-3, comprising a monitor body 1, the monitor body 1 comprising: a gas sensor for detecting and sensing leaks; the control circuit is used for receiving and processing the sensor signals, judging whether leakage occurs according to a preset threshold value and triggering a corresponding alarm or alarm device; providing power for the monitor to work, and connecting the monitor with other equipment (such as an alarm system, a monitoring system or a control center) to realize an interface for data transmission and remote control; buttons or switches, etc. The device is characterized in that the monitor body 1 is arranged in an embedded shell 2, one side of the shell 2 is provided with an opening, an end cover 3 is arranged at the opening, the cross section area of the end cover 3 is larger than the cross section area of the opening of the shell 2, so that the shell 2 can be embedded in a box body or a wall body; in this embodiment, two symmetrical outer walls of the housing 2 are provided with a bayonet 8, and a bayonet 9 matched with the bayonet is extended outwards on the end cover 3, and the bayonet 9 and the bayonet 8 generate a clamping effect to enable the end cover 3 to be mounted on the housing 2.

The outer surface of the end cover 3 is inclined upwards along four sides to form an upper end surface 4, and a hump-type air guide sleeve 5 is outwards arranged on the upper end surface 4 in an protruding way; the air guide sleeve 5 is connected with the upper end surface 4 through the air guide plate 11 which is upwards gathered relative to the upper end surface 4 at the periphery of the air guide sleeve, and the air guide plate 1 plays a role in raising air flow. Specifically, the hump-type air guide sleeve 5 is formed by two connected bulges with the same shape and size, the convex parts of the two bulges are humps, and the concave parts between the two bulges are humps. The air guide sleeve 5 is provided with a high division bar 6 and a low division bar 7 which are staggered up and down, and the gap between the high division bar 6 and the low division bar 7 is communicated with the inner space of the shell 2. Each protrusion is formed by the upper and lower alternate spacing of the upper and lower parting strips 6 and 7.

The design of the air guide cover is mainly used for improving the air flow guiding mode so as to reduce external interference, particularly, a hump type design is adopted when the external air flows or the air pressure changes, the flow path of the air flow is changed, and the air flow can generate resistance and vortex when contacting the hump, so that the speed of the air flow is slowed down, the air flow is guided to a specific direction, and the flow direction of the air flow is controlled; meanwhile, the guide cover is provided with the high division bars 6 and the low division bars 7 which are staggered up and down, gaps between the high division bars and the low division bars allow air flow to pass through, so that an air flow guiding mode is effectively improved, external air flow is subjected to partial resistance when entering the inside of the monitor, the possibility of external interference is reduced, the performance and the reliability of the monitor are improved, and the design is critical to the stable operation of the gas fuel leakage monitor, especially under severe external environment conditions.
