Description

A kind of safety helmet with anti-sand function for oil exploitation

technical field

The invention relates to a safety helmet, in particular to a safety helmet with the function of preventing sand and dust for petroleum exploitation.

Background technique

Petroleum is a fluid mineral buried deep in the ground. Initially, people called oily liquid minerals produced in nature as petroleum, flammable gases as natural gas, and solid flammable minerals as asphalt. With the in-depth study of these minerals, it is recognized that they are all hydrocarbon compounds in composition and are related to each other in terms of genesis, so they are collectively referred to as petroleum. In September 1983, the 11th World Petroleum Congress proposed that petroleum is a complex mixture consisting of gaseous, liquid and solid hydrocarbon compounds and a small amount of impurities that exist in nature. Therefore, oil extraction also includes natural gas extraction.

The role of oil in the national economy Oil is an important energy source. Compared with coal, it has high energy density (the combustion heat of oil of equal weight is 50% higher than that of standard coal), convenient transportation and storage, and less pollution to the atmosphere after combustion. advantage. Fuel oil extracted from petroleum is the main fuel for various kilns in transportation tools, power station boilers, metallurgical industry and building materials industry. Petroleum-based liquefied gas and pipeline gas are high-quality fuels for urban residents' living applications. Airplanes, tanks, ships, rockets, and other spacecraft also consume large amounts of petroleum fuel. Therefore, many countries regard oil as a strategic material.

During oil exploration, mining workers need to wear safety helmets to ensure safety. However, when surveying in the desert, due to the influence of wind and sand, the workers cannot work normally. The existing safety helmets cannot prevent sand and dust, and people inhale too much sand and dust, which affects their health. , and will reduce work efficiency, so it is urgent to develop a safety helmet with anti-sand and dust function for petroleum exploitation that can block sand and dust, ensure the health of workers, and ensure work efficiency.

SUMMARY OF THE INVENTION

A dial is arranged in the middle of the side surface, and a brush is arranged on the right side of the horizontal plate, and the brush is in contact with the outer surface of the transparent window.

Preferably, a dust-proof net is also included, and a dust-proof net is installed at the listening port, the diameter of the dust-proof net can be 0.5 mm, and the material of the dust-proof net is stainless steel.

Preferably, the material of the mask is silica gel, and the thickness of the mask is 0.6 cm.

Preferably, multiple layers of detachable non-woven fabrics are arranged in the dust-proof ventilation cover.

Preferably, the transparent window is made of PC plastic.

Working principle: When workers conduct oil surveys in a relatively good environment, they can remove the mask through the first connector and fasten the cap on the head. When carrying out oil exploration in the desert with harsh environment, the mask can be connected to the cap body through the first connector, people's heads are placed inside the cap body and the mask, and the mask can be connected through the second connector. The staff can see the outside world through the transparent window, and can breathe through the dust ventilator, which can also prevent the outside dust from being inhaled into the human body, which ensures the health of the staff, and can also hear the outside world through the listening port. The mask can block the external sand and dust. Keep your face and head clean.

Because the first connecting piece includes a connecting rod, an I-shaped guide strip and a concave clip, the bottom of the cap body is provided with connecting rods at even intervals in the circumferential direction, the bottom of the connecting rod is connected with an I-shaped guide strip, and the top of the mask is provided with The concave clip matched with the I-shaped guide strip, the length of the concave clip is consistent with the perimeter of the mask, when it is necessary to connect the mask and the cap body, put one end of the concave clip on the I-shaped guide strip. On the outside, push the concave clip to move along the axial direction of the I-shaped guide strip, when the entire concave clip is matched with the concave clip.

Because the second connector includes a magnetic strip and an iron, one end of the mask is provided with a magnetic strip, the magnetic strip is wrapped inside one end of the mask, the other end of the magnetic strip is provided with an iron, and the magnetic strip is also wrapped inside the other end of the mask. When people put their heads in the cap body and the mask, align the magnetic strip with the suction iron, attract the magnetic strip under the action of the suction iron, and connect the mask to prevent the mask from opening.
