Anti-explosion beacon and liquid storage tank

Abstract

The invention provides an anti-explosion beacon and a liquid storage tank, and relates to the technical field of explosion prevention. The anti-explosion beacon comprises a signal transfer assembly, an energy converter, a filler and a protection cover, wherein the protection cover is connected with the signal transfer assembly, and an accommodating cavity is formed between the protection cover andthe signal transfer assembly; the energy converter is arranged in the accommodating cavity and connected with the signal transfer assembly; the energy converter is used for converting an electric signal transferred by the signal transfer assembly to an acoustic signal and transmitting the acoustic signal; and the filler is fully filled into the accommodating cavity to remove air between the energy converter and the protection cover. According to the anti-explosion beacon, the filler is fully filled into the accommodating cavity, the air between the energy converter and the protection cover isremoved, and the attenuation of sound transmission is reduced, so that a higher sound signal can be transmitted.

Description

technical field [0001] The invention relates to the field of explosion-proof technology, in particular to an explosion-proof beacon and a liquid storage tank. Background technique [0002] With the development of electronic technology, the detection of liquid storage tanks in the petrochemical industry and large tanks storing certain flammable and explosive chemical liquids has gradually changed from manual to detection robots. The detection requirements have also changed from the original need to empty the tank and clean it before testing, to the fact that the tank can be tested directly in the liquid without emptying the tank. [0003] Using an unmanned robot to work in the tank requires precise positioning of the robot's position in the tank in order to successfully complete the inspection of the tank. Due to the special use environment and safety considerations in liquid media, the use of optical and radio wave sensors is greatly restricted, while acoustic navigation eq...

AI Technical Summary

Problems solved by technology

Due to the special use environment and safety considerations in liquid media, the use of optical and radio wave sensors is greatly restricted, while acoustic navigation equipment has unique advantages in liquid media, which can simultaneously meet high-precision and long-distance positioning requirements, and can make up for the shortcomings that radio waves cannot be used for positioning due to fast attenuation in liquid media, but the acoustic signal attenuation is serious in traditional explosion-proof beacons, and it is impossible to transmit large acoustic signals
