Description

Technical Field

[0001] This invention relates to the field of occupational safety and health protection technology in mines, specifically to a mine-use chest-back breathing dust detection device. Background Technology

[0002] Various harmful gases and dusts are present during mining operations. Dust hazards are one of the major natural disasters in mines; excessively high concentrations can cause pneumoconiosis and coal dust explosions, affecting safe production. Therefore, dust monitoring is a crucial aspect of ensuring safe coal mine production. This requires the use of dust detection devices in coal mines to monitor the surrounding air and determine if harmful gases and dust levels exceed safe limits. Existing dust detection devices, commonly used underground to monitor dust and ensure worker safety, are placed directly on a support base. These devices are easily damaged by accidental tipping over by workers, reducing their lifespan and making it inconvenient to monitor dust levels in different areas of the mine roadway. Furthermore, existing dust detection devices struggle to measure the amount of dust inhaled by workers, and continuous monitoring is difficult. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a mine chest and back breathing dust detection device that can detect the amount of dust inhaled by workers in real time and facilitates data observation and measurement of various work areas.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a mining chest and back breathing dust detection device, comprising a partitioned dust mask, a hose, an explosion-proof shell and a shoulder strap arranged in sequence, wherein the explosion-proof shell is installed on the front side of the shoulder strap;

[0005] The partitioned dust mask includes a main side, an auxiliary side, an active air duct, and a passive air duct. The main side covers the user's mouth and nose. The auxiliary side is located to the left or right of the main side. The active air duct is located at the active air duct connection port on the auxiliary side, and the passive air duct is located at the passive air duct connection port on the main side. A first airflow sensor, a rotation synchronization sensor, and a fan blade are installed inside the active and passive air ducts via a pair of front-to-back connected three-pronged brackets. A dust sensor is also provided at the passive air duct. The first airflow sensor is installed on the air vent three-pronged bracket, and the rotation synchronization sensor is installed at the fan blade bearing, so that the fan blade bearing of the active air duct rotates synchronously with the fan blade bearing of the passive air duct during air intake.

[0006] The explosion-proof enclosure includes an exhaust port, a hose connection port, and a display screen located on the front end. Inside the explosion-proof enclosure are installed a second airflow sensor, a battery, and a dust collection and analysis component, which includes a cyclone dust collector and a data processor. The exhaust port is located at the top of the explosion-proof enclosure, and the hose connection port is located on the side of the explosion-proof enclosure. The active air duct is connected to the cyclone dust collector through a hose and the hose connection port. When dust-laden gas enters the cyclone dust collector through the hose connection port, the cyclone dust collector collects the dust and then discharges the gas through the exhaust port.

[0007] Preferably, the main side of the dust mask is an isosceles triangle with the pointed end facing upwards, and the auxiliary side of the dust mask is an isosceles triangle with the pointed end facing downwards. The auxiliary side of the dust mask is smaller than the main side of the dust mask, and the two are integrally formed and flush at the bottom.

[0008] Preferably, the auxiliary side of the dust mask consists of a filter structure disposed outside the main side of the dust mask, as well as an air inlet and a closed area with the same ventilation area as the main body of the dust mask, which facilitates the collection of dust inhaled by workers based on their breathing.

[0009] Preferably, the shoulder strap is connected to the explosion-proof shell by Velcro, making it easy for staff to remove and inspect it at any time.

[0010] Preferably, the fan blades in both the active and passive air ducts are three blades evenly arranged in a 35° spiral configuration.

[0011] Preferably, the explosion-proof housing is equipped with a storage card to store real-time data analyzed by the data processor.

[0012] Preferably, the explosion-proof housing is equipped with a real-time positioning system to facilitate the measurement of the amount of dust absorbed by workers when working in various areas of the tunnel.

[0013] Preferably, the two sets of dust sensors are respectively installed on the outer wall of the middle part of the three-pronged support of the air vents on the front and rear sides of the passive ventilation duct, so as to facilitate the measurement of the amount of dust absorbed by the workers when working in various areas of the roadway.

[0014] The beneficial effects of this invention are:

[0015] 1) By setting up partitioned dust masks, dust can be inhaled simultaneously when staff breathe, thus enabling the detection of the amount of dust inhaled by staff during work;

[0016] 2) By connecting the partitioned dust mask to the explosion-proof enclosure equipped with a data processor, the detected dust enters the explosion-proof enclosure for analysis and collection, and the real-time results can be displayed on the screen, making it convenient for staff to observe the real-time detection data;

[0017] 3) By setting a shoulder strap and fastening it to the chest of the staff, the device can be used to detect and analyze dust in various areas of the roadway while the staff is working. It is also less likely to be accidentally knocked over and damaged, and it is easy to remove the device at any time to observe the data. Attached Figure Description

Detailed Implementation

[0028] To better understand the improvements made by the present invention compared to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] like Figure 1As shown in Figure 9, a mining chest-back breathing dust detection device mainly consists of a partitioned dust mask A, a hose C, an explosion-proof shell B, and a shoulder strap 11 arranged in sequence. The explosion-proof shell B is installed on the front side of the shoulder strap 11, and the shoulder strap 11 is connected to the explosion-proof shell B by Velcro, so that the operator can wear the device and remove the device at any time to observe data.

[0030] The partitioned dust mask A mainly consists of a main dust mask side 5, an auxiliary dust mask side 8, an active air duct A1, and a passive air duct A2. The main dust mask side 5 covers the user's mouth and nose, while the auxiliary dust mask side 8 is located to the left or right of the main dust mask side 5. The main dust mask side 5 is an isosceles triangle with its pointed end facing upwards, while the auxiliary dust mask side 8 is an isosceles triangle with its pointed end facing downwards. The auxiliary dust mask side 8 is smaller than the main dust mask side 5, and both are integrated and flush at their bottom edges. The auxiliary dust mask side 8 consists of a filter structure located outside the main dust mask side 5, as well as an air inlet and a closed area with the same ventilation area as the main dust mask body.

[0031] The active air duct A1 is located at the active air duct connection port 7 on the auxiliary side 8 of the dust mask, and the passive air duct A2 is located at the passive air duct connection port 6 on the main side 5 of the dust mask. The active air duct A1 and the passive air duct A2 are equipped with a first air volume sensor 2, a rotation synchronization sensor 3 and a fan blade 4 through a pair of three-pronged brackets connected front and rear. The passive air duct A2 is equipped with a dust sensor 1.

[0032] Both the active ventilation duct A1 and the passive ventilation duct A2 contain three fan blades arranged evenly in a 35° spiral configuration. Two sets of dust sensors 1 are respectively installed on the outer wall of the middle section of the three-pronged support for the air vents on the front and rear sides of the passive ventilation duct A2. The first airflow sensor 2 is installed on the three-pronged support for the air vents, and the rotation synchronization sensor 3 is installed at the bearing of the fan blade 4. This ensures that the bearing of the fan blade 4 in the active ventilation duct A1 rotates clockwise in sync with the bearing of the fan blade 4 in the passive ventilation duct A2 when air is drawn in, thus synchronously drawing in dust when the worker breathes, thereby collecting the dust inhaled by the worker during work.

[0033] The explosion-proof enclosure B mainly consists of an exhaust port 9, a hose connection port 10, and a display screen 12 located on the front face. Inside the explosion-proof enclosure B are installed a second airflow sensor 13, a battery 16, and a dust collection and analysis component 17, which includes a cyclone dust collector and a data processor 14. A memory card 15 is also installed inside the explosion-proof enclosure B to store real-time data analyzed by the data processor. Simultaneously, the explosion-proof enclosure B is equipped with a real-time positioning system, which, in conjunction with the partitioned dust mask A, facilitates the measurement of the amount of dust inhaled by workers in different areas of the tunnel.

[0034] Exhaust port 9 is located at the top of explosion-proof enclosure B, and hose connection port 10 is located on the side of explosion-proof enclosure B. Active air duct A1 is connected to cyclone dust collector through hose C and hose connection port 10. When dust-laden gas enters cyclone dust collector through hose connection port 10, cyclone dust collector collects dust and discharges gas through exhaust port 9. The collected dust can be used for other experiments.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
