Description

Technical Field

[0001] This utility model belongs to the field of gas detection and environmental safety monitoring technology, and in particular relates to a gas detection alarm device with wind direction and wind speed display. Background Technology

[0002] In petrochemical and hazardous chemical storage and transportation sites, gas leaks are a major safety risk. Existing gas detection and alarm devices mostly focus on gas concentration monitoring. Although they can provide local audible and visual alarms, they lack auxiliary information such as ambient wind direction and speed in practical applications. This is because the diffusion direction of a gas leak in the working environment is closely related to wind speed. Relying solely on concentration alarms cannot provide wind direction guidance or indications for personnel evacuation, especially in open or weak wind environments, where personnel may have difficulty quickly determining the upwind direction and thus misjudging safe areas.

[0003] Gas detection devices on the market are often limited in function and have low integration. Most are independent gas detectors or wind direction and speed meters, requiring separate installation and wiring on-site. This leads to complex gas detection and early warning systems, high operation and maintenance costs, and a lack of integrated data display and linked alarms. Moreover, most solutions combining meteorological parameters and gas detection use a split design, failing to achieve true integrated operation and lacking directional alarms and visual guidance functions for gas leak scenarios. Utility Model Content

[0004] In view of this, the present invention aims to propose a gas detection alarm device with wind direction and wind speed display, so as to solve the problem that the existing gas detection alarm devices have single functions and lack wind direction and wind speed information integration, which makes it impossible to provide effective evacuation guidance in the event of gas leakage.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a gas detection alarm device with wind direction and speed display, comprising an upper cover, a display screen integrated circuit board, a battery, a housing, an antenna, a sensor mounting housing, a gas sensor, an audible and visual alarm, a sensor circuit board, and an ultrasonic wind speed and direction sensor. The upper cover has a viewing window. The display screen integrated circuit board integrates a display screen, the position of which corresponds to the viewing window. The display screen integrated circuit board is connected to the battery. Both the display screen integrated circuit board and the battery are housed within the housing. The housing is connected to the antenna, gas sensor, and audible and visual alarm, all of which are electrically connected to the display screen integrated circuit board and the battery. The sensor mounting housing has sensor holes. A sensor circuit board is housed within the sensor mounting housing and is electrically connected to the display screen integrated circuit board. Multiple ultrasonic wind speed and direction sensors are integrated on the sensor circuit board, the positions of which correspond to the sensor holes. The upper cover is connected to the top of the housing, and the bottom of the housing is connected to the sensor mounting housing.

[0006] Furthermore, the sensor mounting housing is connected to a wind direction reflector at the bottom.

[0007] Furthermore, the sensor mounting housing and the wind direction reflector are connected by a central stud and a hexagonal stud with a nut. The central stud is located at the center, and there are multiple hexagonal studs evenly distributed around the outer periphery of the central stud.

[0008] Furthermore, the wind direction reflector is connected to the column below.

[0009] Furthermore, the wind direction reflector is connected to the column via an adapter ring.

[0010] Furthermore, the window is encapsulated with transparent glass.

[0011] Furthermore, the transparent glass is bonded to the inside of the upper cover using sealant.

[0012] Furthermore, the display integrated circuit board is mounted on the battery mounting bracket by screws, the battery is connected to the battery mounting bracket, and the battery mounting bracket is fixed inside the housing by screws.

[0013] Furthermore, the housing is also connected to a handle and a button. The handle is connected to the housing, and the button is electrically connected to the display integrated circuit board and the battery. The antenna, button, gas sensor, and audible and visual alarm are locked onto the threaded hole of the housing by their own threads.

[0014] Furthermore, the sensor circuit board is encapsulated in the sensor mounting housing using resin sealant.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention integrates gas concentration detection and ultrasonic wind speed and direction monitoring into a single device through an integrated design. This effectively solves the problems of traditional solutions, such as single device function, low integration, and the need for separate installation and wiring, leading to system complexity and high maintenance costs. This design reduces the number of on-site devices, significantly lowering installation and maintenance costs, and enables simultaneous acquisition and centralized display of gas concentration, wind direction, and wind speed data. The device centrally displays key information such as gas concentration, wind direction, wind speed, and device status on a single interface, facilitating quick access and understanding by on-site personnel and providing intuitive data support for emergency decision-making.

[0016] This invention particularly enhances the safety guidance function in gas leak accidents. By accurately measuring wind direction and speed data without start-up wind speed limitations using an ultrasonic sensor, and dynamically indicating wind direction with arrows or text on a display screen, it can directly provide clear wind direction guidance and prompts to personnel during emergency evacuation. This effectively overcomes the risk of personnel misjudging safe areas due to difficulty in quickly determining upwind direction in open or weak wind environments, avoiding potential casualties and improving the safety and efficiency of emergency evacuation.

[0017] This invention boasts excellent structural adaptability. The device employs a modular design, allowing for easy switching between portable handheld use and fixed column-mounted installation by replacing the bottom structure. This accommodates diverse scenarios, from rapid deployment of temporary monitoring points to long-term fixed monitoring, thus achieving the device's versatility. This design enhances the equipment's application flexibility, making it more widely applicable to various situations requiring real-time monitoring of hazardous gas leaks, such as petrochemical, chemical, storage and transportation, and fire emergency response.
