Description

Technical Field

[0002] During inspection and maintenance work in the petrochemical industry, when the on-site environment becomes dangerous, affected by factors such as the ambient light, it is difficult for escapees to directly find the escape direction when evacuating dangerous places, resulting in missing precious escape time and causing casualties.

[0003] In emergency rescue operations, when the wind is weak in the on-site working environment, the hazardous gas concentration detector cannot determine the exact installation position according to the wind direction and wind force, which will cause the detection instrument to detect the hazardous gas values ​​inaccurately and easily cause detection errors, thereby causing rescue personnel to misjudge the hazardous gas concentration and risky rescue operations, resulting in more casualties. In fire linkage operations, the site cannot accurately detect the electronic data of wind direction and wind force in real time. This device can upload the detection data to the corresponding security platform for storage through the regional network.

[0004] In other places where clear directions are required, such as airport buildings, terminal buildings, railway stations, subway stations and other places where emergency evacuation of personnel is required, this device can provide clear wind direction and route indications.

[0034] The present embodiment is described with reference to the accompanying drawings. 1. A regional mobile device with wind direction indication, characterized in that it comprises:

[0035] A transparent shell 2, at least one ultrasonic wind direction sensor 2-2 is sealed and connected on the top wall, a wind direction reflecting plate 1 is arranged on the top outer wall, and the wind direction reflecting plate 1 is arranged opposite to all the ultrasonic wind direction sensors 2-2, a light display screen 2-10 is arranged inside the transparent shell 2, and the display surface of the light display screen 2-10 is visible from the periphery, all the ultrasonic wind direction sensors 2-2 and the light display screen are electrically connected to the display screen integrated circuit board 2-4, and a display screen integrated circuit board 2-4 and a battery 2-8 are arranged inside the transparent shell 2, and the battery 2-8 is electrically connected to the display screen integrated circuit board 2-4; the battery 2-8 is powered by the battery 2-8, which can increase the overall endurance, and can support the portable and long-term use of the device, that is, it can be configured with rescue equipment in fire linkage, and can also be placed in other work sites and places where personnel need to be evacuated for independent operation, achieving the purpose of diversified use of the device. Specifically, the wind direction reflecting plate 1 is installed on the outer wall of the top of the transparent shell 2 by the first screw 1-1. The use mechanism of the wind direction reflector 1 and the ultrasonic wind direction sensor is explained: the design of the wind direction reflector is based on the time difference method in the ultrasonic wind speed measurement system. The time difference method calculates the wind speed by measuring the propagation time difference of ultrasonic waves in two relative directions. In the absence of a reflector, ultrasonic waves propagate directly from the transmitter to the receiver, and when there is wind speed, the wind affects the propagation speed of the ultrasonic wave, thereby generating a time difference. The wind direction reflector increases the measurement path by reflecting the ultrasonic signal, making the measurement of the wind speed more accurate. Existing technology can be used.

[0036] As for the ultrasonic wind direction sensor 2-2, the second screw 2-3 can be used to fix it on the transparent housing 2, and the screw connection is convenient for fixing and connecting.

[0037] The lower shell 3 is sealed and connected to the open end of the transparent shell 2 to support the entire device.

[0038] In this embodiment, the lower shell 3 is a metal shell, and the lower shell 3 is connected to the transparent outer shell 2 by threads. In this way, the purpose of explosion-proof can be achieved, thereby improving the use of the device in special working environments.

[0039] In this embodiment, a handle 3-3 is provided on one side of the lower housing 3. The design of the handle 3-3 can increase the convenience of holding the device when moving, thereby increasing the mobility of the device.

[0040] In this embodiment, the handle 3-3 is connected to the lower shell 3 through the handle connecting plate 3-2. This design can increase the convenience of installation and maintenance. By setting the handle connecting plate 3-2 in the middle, the connection stability can be ensured when the lower shell 3 is in an arc shape as a whole, because the side of the handle connecting plate 3-2 close to the wall of the lower shell 3 can be set to an arc shape, thereby achieving a better fit. The connection between the handle connecting plate 3-2 and the lower shell 3 can be an integrated molding method or a welding method. The handle connecting plate 3-2 and the handle 3-3 are connected by the cooperation of the fourth screw 3-1 and the bolt 3-4. The specific specification of the fourth screw 3-1 can be an M8×12 screw. The quantity can be selected according to actual needs.

[0041] In this embodiment, each of the ultrasonic wind direction sensors 2-2 is connected to the transparent housing 2 via a sealing rubber ring 2-1. As a preferred solution, an opening is provided on the top wall of the transparent housing 2 for passing the ultrasonic wind direction sensor 2-2, the ultrasonic wind direction sensor 2-2 is installed from the inside of the transparent housing 2 and passes through the opening on one side, and a sealing rubber ring 2-1 is provided at the connection with the opening to achieve a sealed connection, and at the same time, the area where all the ultrasonic wind direction sensors 2-2 are located is further sealed by pouring epoxy resin glue, thereby achieving effective isolation of the area where the ultrasonic wind direction sensor 2-2 is located from the lower battery and other areas, which is conducive to the use of the device in an explosion-proof environment.

The display integrated circuit board 2-4 can convert the signal collected by the sensor into an electrical signal, and display the arrow or text of the wind direction through the screen light, so that the operator can judge the direction of escape and avoid casualties.

[0043] In this embodiment, the battery 2-8 is connected to the bottom wall of the lower housing 3 through the battery bracket 2-7. The battery 2-8 is installed through the battery bracket 2-7, so that the battery 2-8 of the device can be suspended to a certain extent, reducing the impact of the bump on the battery 2-8, thereby improving the safety of the device during use. Specifically, the battery bracket 2-7 can be installed on the inner bottom wall of the lower housing 3 through the third screw 2-6.

[0044] In this embodiment, the display screen integrated circuit board 2-4 is connected to the bottom wall of the lower shell 3 through a plurality of hexagonal studs 2-5. This installation method is safe and reliable and can support the display screen integrated circuit board 2-4 in the air, reduce the impact on the display screen integrated circuit board 2-4 during collision, improve the safety of the device, and cooperate with the explosion-proof design to improve the safety of the device operation.
