[0028] In the description of the embodiments of the present invention, unless otherwise specified, the meaning of "a plurality" refers to two or more.

[0029] The present invention combines an air curtain with a mine safety helmet, uses the pollution blocking effect of the air curtain jet to prevent operators from inhaling high-concentration dust, effectively ensures a clean breathing microenvironment while improving the comfort of the protection process, improves the actual respiratory protection effect, and maximally avoids affecting normal operations, having an attractive application prospect.

[0030] As Figures 1 to 7 shown, the present invention provides a mine-integrated wearable air supply protection device, including: A helmet 1, including an outer shell 101 and an inner shell 102. The inner shell 102 is located in the concave part of the outer shell 101. There is a cavity 2 between the outer shell 101 and the inner shell 102. The rear edges of the outer shell 101 and the inner shell 102 are connected. An air supply opening 20 is formed between the front edges of the outer shell 101 and the inner shell 102. The opening of the air supply opening 20 faces downward. A first air inlet 3 is provided on the rear side of the outer shell 101.

[0031] Air supply device, including a box body 4, a blower 5, a connecting piece 6 and an air filter 7. One side of the box body 4 is provided with an air outlet 8, and the air outlet 8 is communicated with the first air inlet 3 through an air supply pipe 17. Another side wall of the box body 4 is provided with a second air inlet 9. The blower 5 is located inside the box body 4, and the air inlet end of the blower 5 is clamped at the second air inlet 9. The air filter 7 is located between the air outlet 8 and the blower 5, and the air filter 7 filters the dust in the air inhaled by the blower 5. The connecting piece 6 is fixed to the outer side wall of the box body 4.

[0032] During use, the air supply device is suspended around the worker's waist by using the connecting piece 6, and then the helmet 1 is worn. The blower 5 in the air supply device inhales the dust-containing air flow in the surrounding environment into the box body 4. After the dust in the inhaled air is filtered by the air filter 7, it enters the cavity 2 of the helmet 1 through the air outlet 8, the air supply pipe 17 and the first air inlet 3, and finally is sent out from the air supply port 20, forming an air curtain on the worker's face. The air curtain can isolate the dust from the worker's face, thereby reducing the amount of dust inhaled by the worker. At the same time, there is no pressure on the face, and the air curtain can also blow air to the worker to avoid sultriness, with strong comfort.

[0033] The air curtain formed by the air supply port 20 has a pollution blocking effect, creating a clean breathing microenvironment for the wearer in high-pollution working places in mines.

[0034] The outer shell 101 of the helmet 1 uses glass fiber reinforced plastic, with a density of about 2.49 g / cm 3 and a relative density between 1.5 and 2.0, a tensile strength between 245 and 465 kgf / mm 2 and a Young's modulus between 5.3×10³ and 11.1×10³ kgf / mm 2 It has the characteristics of light weight, high specific strength, corrosion resistance, good electrical insulation performance, good thermal insulation performance, good resistance to instantaneous ultra-high temperature, excellent water resistance, flame retardancy, and small deformation.

[0035] The multi-layer density linings such as the buffer pad and sweat-absorbing band inside the inner shell 102 use materials such as expanded polystyrene and Coolmax fiber knitted fabric, with a small relative density, low thermal conductivity, small water absorption, resistance to impact vibration, heat insulation, sound insulation, moisture-proof, shock absorption, and excellent dielectric properties, which can improve its comfort while ensuring the impact resistance of the helmet.

[0036] The air supply pipe 17 is made of high-strength, wear-resistant, corrosion-resistant, flame-retardant and explosion-proof materials such as high-polymer composite materials. The required fastening cap band and lower jaw strap of the helmet 1 are configured the same as those of common safety helmets, which are used to prevent the helmet 1 from falling off during wearing, and no specific markings are shown in the figure.

[0037] The air supply duct 17 sends filtered air into the cavity 2 through the first air inlet 3. The first air inlet 3 is arranged at the rear of the helmet 1, which can reduce the required length of the air supply duct 17 and minimize the frictional resistance of the duct as much as possible.

[0038] For example: The length of the duct is based on the upper body height of adult males aged 26 to 35 in static human body dimensions, and it is a retractable hose about 856 mm long. The hose with a certain telescopic ability can adapt to people of different body shapes and heights.

[0039] The dust-containing air flow in the surrounding environment is inhaled by the fan 5, purified into filtered air through the air filter 7, and then the filtered air enters the helmet 1 from the air outlet 8 through the air supply duct 17, and finally passes through the cavity 2 and is sent out from the air supply port 20 to protect the underground workers.

[0040] The air filter 7 should select a material with high filtration efficiency, low flow resistance, long continuous use time, and large dust capacity as the filter element. Considering the comprehensive filtration effect and filtration resistance, there can be multiple air filters 7, and multi-stage filtration is used to improve the filtration efficiency and service life.

[0041] Preferably, the number of air filters 7 is two, which can reduce the resistance of air flow while ensuring the filtration efficiency.

[0042] Furthermore, the air filter 7 near the second air inlet 9 conducts primary filtration on the air flow, and the one near the air outlet 8 is a high-efficiency filter to ensure the cleanliness of the filtered air.

[0043] In the embodiment provided by the present invention, a plurality of flow equalizing plates 10 are provided in the cavity 2.

[0044] The cavity 2 has an appropriate width, and an arc-shaped flow equalizing orifice plate can be arranged inside it. While enhancing the impact resistance of the helmet 1, it can evenly transport the filtered air to the air supply port 20.

[0045] Preferably, there are two flow equalizing plates 10 in the cavity 2. One is at the top of the helmet and plays a supporting role, and the other is near the air supply port 20 to ensure the evenness of the air flow at the air supply port 20.

[0046] In the embodiment provided by the present invention, a deflector 11 is provided at the front edge of the outer shell 101, and the deflector 11 is used to guide the air flow.

[0047] For example: The cavity 2 has a width of 32 mm, and one flow equalizing plate 10 is arranged at the top of the head and at the air supply port 20 inside it respectively. The strength requirement of the material of the flow equalizing plate 10 can be slightly lower than that of the outer shell 101. Using acrylonitrile-butadiene-styrene plastic can, while enhancing the impact resistance of the helmet 1, evenly transport the filtered air to the air supply port 20.

[0048] The air supply outlet 20 uses filtered air to form a protective air curtain, with a width set at 32 mm, flowing vertically downward to block environmental polluted air and provide respiratory protection. The deflector 11 is in the shape of a brim, having the same length and arc as the air supply outlet. To fully protect the facial area of personnel, the opening angles of both are preferably 180°.

[0049] In the embodiment provided by the present invention, a power supply 18 is provided inside the box body 4, and the power supply 18 provides energy for the fan 5 and the controller 13.

[0050] In the embodiment provided by the present invention, internal components such as the box body 4, the power supply 18, and the fan 5 should have the characteristics of flame retardancy and explosion protection to adapt to the complex environment underground in mines. The power supply 18 and the fan 5 should be subjected to additional explosion protection treatment. The box body 4 is suspended around the waist of the worker through the connecting piece 6. Therefore, internal components such as the box body 4, the power supply 18, and the fan 5 should also have characteristics such as light weight and simplicity. The outer shell 101 of the box body 4 should be made of a light-weight explosion-proof material.

[0051] Furthermore, a protective net 19 is provided at the second air inlet 9 to prevent the fan 5 from accidentally injuring personnel during rotation and prevent sharp objects in the environment from damaging the fan 5 on the basis of ensuring the normal operation of the fan 5.

[0052] In the embodiment provided by the present invention, the air supply device further includes an air volume adjustment knob 12 and a controller 13. The air volume adjustment knob 12 is located outside the box body 4, and the controller 13 is fixed to the box body 4. The controller 13 is respectively connected to the air volume adjustment knob 12 and the fan 5.

[0053] The air volume adjustment knob 12 is used to adjust the wind speed, and then feedbacks to the controller 13. The controller 13 thus controls the power of the fan 5 to achieve the adjustment of the wind speed, and further changes the air outlet speed of the air supply outlet 20 to adapt to different air curtain requirements.

[0054] In the embodiment provided by the present invention, a display screen is provided on the box body 4. The display screen is connected to the controller 13 and is used to display the power, wind speed, and dust content.

[0055] In the embodiment provided by the present invention, a dust sensor 14 is provided inside the box body 4. The dust sensor 14 detects the dust concentration in the filtered air. The dust sensor 14 is located between the air outlet 8 and the air filter 7, and the dust sensor 14 is connected to the controller 13.

[0056] The dust sensor 14 uses the GP2Y1014AU based on the principle of laser scattering method, with a working voltage of 5V to 7V, a current less than 20mA, and a working temperature of -10°C to 65°C. It can adapt to the underground working conditions, with a size of approximately 46mm×30mm×17.6mm. It can be set between the air outlet 8 and the air filter 7 to obtain real-time data related to the cleanliness of the filtered air and reflect it to the display screen. The wearer can thereby understand the performance of the air filter 7 in real time and prevent the generation of a dirty air curtain at the air supply outlet 20 due to reasons such as a decrease in the filtering capacity of the air filter 7.

[0057] In the embodiment provided by the present invention, according to the dust concentration detected by the dust sensor 14, the dust inhalation concentration of the wearer is obtained. The specific formula is: In the formula, is the inhalation concentration of the wearer, is the dust concentration measured by the dust sensor, is the air supply inhalation exposure rate, indicating the proportion of the air curtain air supply in the air inhaled by the wearer, measured by the air supply equipment in the calibration environment, is the environmental impact coefficient, determined by environmental parameters such as environmental air flow and temperature, is the environmental dust concentration, measured by other on-site equipment.

[0058] In the embodiment provided by the present invention, a wind speed sensor 15 is provided inside the box. The wind speed sensor 15 detects the wind speed , and the wind speed sensor 15 is located between the air outlet 8 and the air filter 7. The wind speed sensor 15 is connected to the controller 13.

[0059] The wind speed sensor 15 selects the JT1411 micro wind speed sensor, which is small in size, high in sensitivity, can be integrated into the circuit, with a maximum size of only 7 mm, and can be flexibly arranged on the circuit board or the cabinet. The digital signal and analog signal outputs can be switched arbitrarily. The wind speed range is 0 m / s to 20 m / s, the wind speed resolution is 0.01 m / s, the response time is 0.2 s, and the wind temperature range is -25 °C to 70 °C, which can meet the requirements of the underground environment. Considering the connection and use with the display screen, the wind speed sensor 15 is set inside the connection of the air outlet 8 and the air supply pipe 17, rather than inside the connection of the first air inlet 3 and the air supply pipe 17, which is convenient for wiring and connection between the wind speed sensor 15, the display screen and other components. Setting it inside the pipeline can prevent the environmental air flow from affecting it and is convenient for maintenance. It can measure the wind speed data of the filtered air supplied to the helmet 1 in real time and reflect it to the display screen. The wearer can thus understand the current air supply situation in real time and estimate the operation status of components such as the fan 5, preventing the air supply rate at the air supply port 20 from being too large or too small. To intuitively display the current air supply effect, the wind speed displayed on the display screen is based on the wind speed at the air supply port 20. Since the wind speed sensor 15 is set at the connection of the air outlet 8 and the air supply pipe 17.

[0060] The wind speed sensor 15 is set inside the connection of the air outlet 8 and the air supply pipe 17, which can prevent the environmental air flow from affecting it and is convenient for maintenance, and can measure the wind speed of the filtered air supplied to the helmet 1 in real time.

[0061] In the embodiment provided by the present invention, according to the wind speed detected by the wind speed sensor 15, the wind speed of the air supply port is calculated. The specific formula is: is the wind speed at the air curtain outlet, is the wind speed measured by the wind speed sensor, is the area of the air curtain outlet, is the cross-sectional area of the air supply pipe In the embodiment provided by the present invention, since the performance of the air filter 7 directly affects the cleanliness of the filtered air and the protection effect of the equipment, the dust sensor 14 and the wind speed sensor 15 are used for collaborative monitoring. When the sensor measures the wind speed 15 is less than the resistance threshold wind speed it indicates that the resistance of the air filter 7 may reach the final resistance, and the dust particles it contains reach the dust holding capacity of the filter, and the filter element needs to be replaced. The resistance threshold wind speed The specific calculation formula is: In the formula, is the air density, is the fan air pressure, is the gear coefficient of the fan, is the total resistance of the air filter, is the cross-sectional area of the air filter.

[0062] In the embodiment provided by the present invention, a gasket with a number of holes is arranged inside the inner shell 102, which can prevent the head from being in contact with the inner shell 102 for a long time without ventilation, resulting in stuffiness and discomfort.

[0063] The present invention uses an air curtain to isolate personnel from the discrete phase in the underground environment. It can protect the wearers without affecting their line of sight and operation. Considering the perspective of individual use, its comfort is much higher than that of dust masks. Considering the perspective of combined use, it can be used simultaneously with masks and other equipment without mutual interference.

[0064] For underground workers who must wear safety helmets, the present invention will not cause additional burdens due to wearing protective equipment, and has significant advantages compared with masks. Different from powered air-purifying respirators and other enclosed helmets, using an air curtain to separate dust does not require accessories such as face masks and will not produce a sense of enclosure on the human body, thus improving comfort both physically and psychologically. Integrating the safety helmet, air filtration, and fan air supply into one, it is convenient to wear and carry, and can provide protection for personnel while meeting the needs of movement and operation. Integrating the wind speed and dust sensors into the protective equipment can, while providing individual protection, monitor and evaluate the protective effect of the equipment in real time and ensure the normal operation of the equipment.

[0065] The present invention not only has the advantage of air curtain dust separation and can be used simultaneously with equipment such as masks, but also has the performance of a safety helmet. The air box power supply can be integrated with the underground miner's lamp power supply to maximize the use of the accessories. While increasing protective measures and enhancing the protective effect, it reduces the burden on workers and provides a new method for mine individual protective equipment.

[0067] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made.
