UA146540U - DEVICE FOR ORIENTATION IN LIMITED VISIBILITY - Google Patents

Abstract

The device for orientation in conditions of limited visibility consists of a helmet case, an ultrasonic sensor, a power supply, a microprocessor. The device includes a screen for displaying information on a flexible bracket, a button to turn on and off.

Description

The utility model belongs to the field of firefighting equipment, namely devices that help a firefighter orient himself in conditions of limited visibility.

As a result of the fire, the following occurs: rising high temperatures, smoke, gassing, collapse of structures of buildings and structures, explosions of technological equipment and devices, falling of burnt trees, as well as collapse. During the reconnaissance and direct fire extinguishing, units of the ORS of the CZ are faced with the 3 above-mentioned factors, which in turn slow down the process of conducting reconnaissance, evacuation and rescue of people, localization and liquidation of the fire. Therefore, the use of devices with the help of which you can navigate in conditions of limited visibility allows you to significantly reduce the time of conducting fire reconnaissance, evacuating people from the smoky area and extinguishing the fire.

The well-known fireman's helmet (patent MO KK20190095032А dated August 14, 2019). The proposed helmet is designed to protect the head during work in a place unsuitable for breathing.

The main elements of the proposed device are a thermal imaging camera, a control and power unit, sensors for temperature, humidity, air composition, as well as temperature, pressure, and the firefighter's pulse. With the help of ZRZ, it is possible to determine the location and m/s for transmitting information to the control panel. Information LCD display, which consists of a transparent rectangular panel, located in front of the firefighter's face on a bracket.

Also known is the fire helmet "S-Tpgy ZtoKe Oimipd Neitei" (re: /Ligetap.sitsb) (the date of the last update of the site 28.01.2016), a helmet with a visor, enables a firefighter to work with low or zero visibility in dense smoke and to navigate in space . The helmet uses augmented reality in conditions of limited visibility, the thermal imaging camera projects an image over the picture that the firefighter sees, and also demonstrates the command, communication and thermal imaging interface.

The closest analogue is a fire helmet (patent Mo KO19269801 dated 09/26/2019). The proposed helmet uses an ultrasonic sensor, the fire helmet includes a helmet with a visor and a location sensor located on the helmet and protected by a fireproof housing. The device also contains a display for displaying graphic information, a microprocessor for processing the received information. The disadvantage of this design is the location of the ultrasonic sensor outside the helmet, which in turn does not protect it from dangerous

Fire factors such as high temperature, as well as the location of the display for information output, which is located on the back of the fire helmet, prevents a full view of the surrounding environment when working outdoors and under conditions when the orientation device is not used, but the work is performed with the head lowered a visor to protect the face and eyes. Also, this method of fastening does not allow the firefighter to focus his vision on this display and obtain the necessary information, because the distance between the face of the firefighter in the helmet and the display is too small. The lack of an on and off button, in a situation where the use of the device is not required, the information displayed on the screen will interfere with the performance of the task.

The basis of a useful model is the task of creating a device for orienting a firefighter in areas of limited visibility, with protected design elements of the device from the action of dangerous fire factors, the ability to display information as needed and in a place convenient for the firefighter.

The task is solved by using an ultrasonic sensor, which is built into the helmet, a screen for displaying information about the distance to an obstacle, fixed on a flexible bracket, and a button for turning it on and off.

Variants of the device for orientation in conditions of limited visibility are shown in the drawing. The drawing and description of the implementation and use of the device for orientation of the firefighter in conditions of limited visibility do not limit the claimed formula of the utility model, but only explain the essence of the utility model.

The device for orientation in conditions of limited visibility consists of a helmet body 1, in which an ultrasonic sensor 2 is built-in, a flexible bracket 3, on which a screen for displaying information (about the distance to an obstacle) is fixed 4, an on and off button 5, a microprocessor 6, a block power supply 7.

The device for orientation in conditions of limited visibility works as follows. When performing the assigned tasks in smoky conditions, the firefighter turns on the device with the switch 5, adjusts the convenient position of the screen for displaying information (about the distance to the obstacle) 4, with the help of a flexible bracket 3, the ultrasonic sensor 2 installed in the helmet body 1, sends and receives signals from ultrasonic sensor 2, which determines the distance to obstacles that are directly in front of the firefighter, the microprocessor b receives information from the ultrasonic sensor 2 and displays information about the distance to the obstacle on the screen for the firefighter to understand the distance to the obstacle 4, the power supply unit 7 ensures uninterrupted operation of the device during battery operation time.
