Description

Technical Field

[0001] This utility model relates to the field of oil depot instrumentation technology, and more specifically, to an audible pressure alarm. Background Technology

[0002] Currently, the pressure inside oil depot pipelines is displayed through relatively intuitive pressure gauges. On-site personnel need to visually observe the pressure inside the pipeline for extended periods of time, which increases the labor intensity and causes visual fatigue for on-site personnel, potentially leading to other production safety accidents. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a sound pressure alarm.

[0004] This utility model is achieved through the following technical solution: a sound pressure alarm, including an explosion-proof housing and an explosion-proof housing cover. A sleeve communicating with the interior is fixedly installed at the bottom of the explosion-proof housing. A pressure sensor is installed inside the sleeve. The outer wall of the bottom end of the pressure sensor is provided with external threads. The explosion-proof housing contains a buzzer, a battery compartment, wiring terminals, and a mainboard processor. The buzzer is located on the right side inside the explosion-proof housing. A through hole is opened through the right side wall of the explosion-proof housing. The battery compartment is electrically connected to the pressure sensor, the buzzer, and the mainboard processor through the wiring terminals. The mainboard processor is communicatively connected to the pressure sensor and the buzzer.

[0005] As a preferred option, the explosion-proof housing has screw holes at the four corners of its top, and the four corners of the explosion-proof housing cover are connected with cross screws that match the screw holes.

[0006] As a preferred option, the battery compartment contains AA batteries.

[0007] As a preferred option, the motherboard processor has a built-in wireless communication module.

[0008] This utility model, by adopting the above technical solutions, has the following beneficial effects compared with existing technologies: The audible pressure alarm effectively solves the problem of visual fatigue for on-site personnel, providing an audible alarm based on a pre-set pressure, thus effectively addressing other safety issues caused by pipeline pressure buildup. This alarm has several advantages: first, it automatically alarms when the set pressure is exceeded; second, it automatically replaces the alarm device to prevent it from malfunctioning due to power shortage; third, it can transmit alarms remotely to the central control room and various duty rooms, thereby eliminating leaks caused by excessive pipeline pressure; and fourth, it saves manpower and reduces the workload of employees. Therefore, it makes pipelines safer when storing oil products, and has practical significance for improving the inherent safety of oil depots.
