Description

Technical Field

[0001] This invention relates to the field of occupational disease protective wearable devices, and more specifically, to a portable wearable device for occupational disease personal protection. Background Technology

[0002] The environment in mines is extremely harsh. Large amounts of dust, harmful gases, noise from machinery, and high temperatures and humidity create the "four pests" that seriously endanger the health of underground workers. These pests must be prevented and controlled. Therefore, portable wearable devices are needed for occupational disease patients to perform protective operations during work.

[0003] In the prior art, a smart wearable device for protecting against occupational diseases in the coal mining industry, with publication number CN 211659100 U, includes: a protective suit with a helmet and internal space; a pure oxygen source connected to the helmet via an oxygen valve; an air source connected to the internal space of the protective suit via an air valve; the electrical control terminals of the air valve and oxygen valve are electrically connected to a controller; the controller is electrically connected to an oxygen concentration sensor installed inside the helmet; the protective suit also has an air circulation device. This utility model uses two portable air sources to mix pure oxygen with air or nitrogen, reducing the use of pure oxygen and preventing dissolved oxygen in the body. This oxygen supply method forms a portable breathing air supply system capable of providing pure air for a longer period of time, and a completely isolated smart wearable device that provides comprehensive, efficient, and reliable protection against the four occupational hazards in the coal mining industry. Using concentrated oxygen mixed with air or nitrogen to create breathing air is more convenient and flexible.

[0004] However, while existing wearable devices can provide adequate oxygen and moisture for personnel inside protective suits and enable real-time monitoring of their physical condition, the head protection of these suits is inadequate when workers are working underground. This allows small stones to fall directly onto the workers' heads, posing a safety hazard. Furthermore, the simultaneous blowing and scraping of the helmet's observation panel while protecting the head is ineffective, reducing the visibility of workers and compromising the suit's overall protective function. Therefore, we propose a portable wearable device for occupational disease personal protection. Summary of the Invention

[0005] To address the problems mentioned in the background, this invention provides a portable wearable personal protective equipment for occupational diseases. This equipment addresses the issues raised in the background art, such as the limited effectiveness of adjustable head protection, which allows small stones to fall and directly contact the worker's head during underground work, posing a safety hazard. Furthermore, the equipment's effectiveness in simultaneously blowing and scraping away debris from the observation panel on the helmet while providing head protection is poor, reducing the worker's visibility while wearing the protective suit.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A portable wearable personal protective equipment for occupational diseases includes a protective suit body, an equipment backpack on the back of the protective suit body, a pressure relief valve on the back of the protective suit body, a delivery pipe fixedly connected to the bottom of the equipment backpack and fixedly connected to the back of the protective suit body, a connecting pipe on one side of the delivery pipe, and a helmet body integrally connected to the top of the protective suit body, with a protective panel on the outer wall of the helmet body. The top of the helmet body is fixedly connected to a fixing box. The inner wall of the fixing box is rotatably connected to a first gear. The outer wall of the first gear meshes with a second gear that is rotatably connected to the inner wall of the fixing box. The outer wall of the second gear is slidably connected to a sliding column. One end of the sliding column is fixedly connected to a sliding rod that is slidably connected to the outer wall of the fixing box. One end of the sliding rod is fixedly connected to a shield. The rotation center of the second gear is fixedly connected to a bevel gear set via a rotating shaft. A connecting cylinder is provided on the top of the fixed box. A connecting fan blade located inside the connecting cylinder is fixedly connected to the outer wall of the bevel gear set. An air supply pipe is fixedly connected to one end of the connecting cylinder, and an air jet pipe is fixedly connected to one end of the air supply pipe. The outer wall of the shield is slidably connected to a connecting rack, and the outer wall of the connecting rack is fixedly connected to a telescopic rod. One end of the telescopic rod is fixedly connected to a cleaning scraper that fits against the surface of the protective panel. When occupational disease workers wear the intelligent protective clothing, in order to improve the protective effect of the protective clothing on the wearer's head and prevent collapse that could cause head injury, and according to the required range of head protection, the first servo motor is activated. The rotation of the first gear drives the rotation of the second gear, which in turn drives the sliding column to slide along the inner wall of the limiting groove, and the sliding rod to slide along the inner wall of the sliding groove. This allows the shield to extend and retract, achieving convenient adjustment of the head protection range for the wearer.

[0007] Preferably, the equipment backpack is used to house a compressed air cylinder or compressed nitrogen cylinder and a compressed oxygen cylinder or chemical oxygen generator, a controller and a battery, as well as a circulation pump, cooling equipment and dehumidification equipment for an air circulation device.

[0008] Preferably, the protective suit is made of flame-retardant and anti-static material, and a temperature sensor and a humidity sensor are installed inside the protective suit.

[0009] Preferably, the helmet body is equipped with a carbon dioxide concentration sensor and an oxygen content sensor, and the oxygen inside the protective suit is supplied through a compressed oxygen cylinder, and the outer wall of the compressed oxygen cylinder is equipped with a pressure gauge, an alarm and a safety valve.

[0010] Preferably, the outer wall of the fixed box is provided with a first servo motor fixedly connected to the rotation center of the first gear, the connection between the outer wall of the second gear and the sliding column is provided with a limit groove, and the connection between the inner wall of the fixed box and the sliding rod is provided with a sliding groove.

[0011] Preferably, a connecting plate is fixedly connected to the bottom of the shield, and a second servo motor is provided on the outer wall of the connecting plate. The output end of the second servo motor is fixedly connected to a connecting gear that meshes with the outer wall of the connecting rack. While driving the jet pipe to adjust the spray angle, it simultaneously scrapes away impurities adsorbed on the surface of the protective panel. The second servo motor is driven by the rotation of the connecting gear, which drives the jet pipe to adjust its operating angle. At the same time, it drives the connecting rack to slide along the outer wall of the shield, and through the connection of the telescopic rod, it drives the cleaning scraper to scrape and clean along the surface of the protective panel, further improving the surface clarity of the protective panel after long-term use.

[0012] Preferably, the rotation center of the connecting gear is fixedly connected to the end of the jet pipe via a rotating shaft. The protective panel is positioned on the movement trajectory of the jet pipe. When adjusting the head protection for the wearer, the mechanical energy generated by the second gear is converted into wind energy through the drive of the mechanical structure and applied to the surface of the protective panel. This prevents the protective panel surface from accumulating excessive dust, which could affect the visibility of the workers. The rotation of the second gear, through the rotation of the bevel gear set, drives the connecting fan blades to rotate. The rotation of the connecting fan blades, through the connection of the air supply pipe, sprays gas from the jet pipe, achieving the effect of blowing away and cleaning the dust adsorbed on the surface of the protective panel.

[0013] Preferably, the outer wall of the shield is detachably connected to a mounting plate, and the inner wall of the mounting plate is provided with a slot at the connection between the shield and the inner wall.

[0014] Preferably, the outer wall of the mounting plate is provided with a nut, and the inner wall of the nut is threaded with a bolt that is slidably connected to the outer wall of the shielding plate. The connection between the outer wall of the shielding plate and the bolt is provided with a positioning groove. When the shielding plate is used to cover and protect the top of the person wearing the protective clothing, the mounting plate is inserted into the outer wall of the shielding plate through the opening of the groove, and the bolt is rotated. Through the limiting action of the nut, the bolt is inserted into the positioning groove, and the protective roller shutter is locked and installed, so as to achieve the effect of covering and protecting the person wearing the protective clothing from all sides.

[0015] Preferably, the inner wall of the positioning groove is provided with internal threads at the connection point with the bolt, and a protective roller shutter is fixedly connected to the bottom of the mounting plate; The protective roller shutter is made of transparent material, and the outer wall of the protective roller shutter has an arc shape. The protective roller shutter is set around the protective clothing, and the overall material of the protective roller shutter is soft silicone.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The shield and air jet pipe provided in this invention can improve the head protection effect of the protective clothing for occupational disease workers when wearing it with the assistance of intelligent protective clothing, and prevent collapse that could cause head injury. According to the required range of head protection, the first servo motor is activated, and the rotation of the first gear drives the rotation of the second gear. The rotation of the second gear causes the sliding column to slide along the inner wall of the limiting groove, and the sliding rod to slide along the inner wall of the sliding groove, so that the shield can extend and retract, achieving the effect of convenient adjustment of the head protection range for the wearer.

[0017] 2. The jet pipe of this invention can convert the mechanical energy generated by the second gear into wind energy through the mechanical structure drive when adjusting the head protection of the wearer. This wind energy is then applied to the surface of the protective panel to prevent the protective panel from accumulating too much dust, which would affect the visibility of the workers. The rotation of the second gear drives the connecting fan blades to rotate through the rotation of the bevel gear set. The rotation of the connecting fan blades, through the connection of the air supply pipe, sprays gas from the jet pipe, achieving the effect of blowing away and cleaning the dust adsorbed on the surface of the protective panel.

[0018] 3. The cleaning scraper provided in this invention can simultaneously scrape away impurities adsorbed on the surface of the protective panel while the spray angle of the driving jet pipe is adjusted. The second servo motor drives the rotation of the connecting gear to adjust the operating angle of the jet pipe. At the same time, it drives the connecting rack to slide along the outer wall of the baffle plate. Through the connection of the telescopic rod, it drives the cleaning scraper to scrape and clean along the surface of the protective panel, further improving the surface clarity of the protective panel after long-term use.

[0019] 4. The protective roller shutter of this invention can, when the top of the person wearing protective clothing is covered by the shielding plate, insert the mounting plate into the outer wall of the shielding plate through the opening of the slot, and rotate the bolt through the limiting action of the nut so that the bolt is inserted into the positioning groove, thereby locking and installing the protective roller shutter, so as to achieve the effect of covering and protecting the person wearing protective clothing from all sides.
