Description

Technical Field

[0001] The present invention relates to the technical field of plateau oxygen production equipment, and in particular to an oxygen production equipment and system for plateau and extremely cold construction environments. Background Art

[0002] Plateau cold weather is a type of climate located in high altitude areas, characterized by cold climate and low oxygen content, usually accompanied by strong sunshine and low temperature, strong radiation, abundant sunshine, low temperature, little accumulated heat, and the temperature decreases with increasing altitude and latitude. Due to the high altitude and thin atmosphere, solar radiation can reach the ground directly, making these areas have longer sunshine hours. At the same time, due to the high altitude, the temperature is relatively low. The plateau environment with extreme temperature and thin oxygen can easily cause people in low altitude areas and those engaged in physical labor to have a state of altitude sickness such as coma and hypoxia. During the construction of plateau tunnels, ventilation is difficult, especially for long-distance construction of tunnels in plateau cold weather. The cold and poor air circulation and oxygen-deficient environment can easily cause altitude sickness among workers.

[0003] With the existing plateau diffuse oxygen generator, during the construction of the tunnel, a large amount of dust, smoke, mechanical exhaust, etc. cannot be removed in time, resulting in the combination of humid and cold gas and dust inside the tunnel, which slows down the air circulation in the cave, slows the oxygen delivery speed, and causes insufficient oxygen content. At the same time, long-term operation can easily cause dust to block the oxygen supply device to varying degrees, reducing the oxygen delivery speed and making the harsh tunnel environment more complicated. At the same time, the low oxygen content can easily cause construction workers to faint due to lack of oxygen, which poses a threat to the personal safety of the workers. In addition, the oxygen inside the tunnel is mixed with dust and water vapor, resulting in low oxygen content inside the tunnel and slow air flow, which affects the combustion of engineering machinery fuel, resulting in incomplete combustion and the generation of harmful gases, threatening the personal safety of workers. The reduced oxygen delivery speed and oxygen content can easily lead to a worse tunnel construction working environment, low efficiency of personnel and machinery operations, and a threat to personal safety.

[0004] Therefore, the present application provides an oxygen production equipment and system for use in high-altitude and cold construction environments to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an oxygen production device and system for high-altitude and cold construction environments to solve the problem that a large amount of dust, smoke, mechanical exhaust, etc. cannot be removed in time during the construction of existing tunnels, resulting in the combination of humid and cold gas and dust inside the tunnel, which makes the air circulation in the cave sluggish, the oxygen delivery speed is slow, and the oxygen content is insufficient. At the same time, long-term operation can easily cause dust to block the oxygen supply device to varying degrees, reduce the oxygen delivery speed, and make the harsh tunnel environment more complicated. At the same time, the low oxygen content can easily cause construction workers to faint due to lack of oxygen, which poses a threat to the personal safety of the workers. In addition, the oxygen inside the tunnel is mixed with dust and water vapor, resulting in low oxygen content inside the tunnel, slow air flow speed, affecting the combustion of engineering machinery fuel, resulting in incomplete combustion, generating harmful gases, threatening the personal safety of workers, and reducing the oxygen delivery speed and oxygen content, which can easily lead to a worse tunnel construction working environment, low efficiency of personnel and machinery operations, and threats to personal safety.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, by setting up a dust absorption component, utilizing the cooperation between the dust suction pipe, the machine base, the rack and the suction seat, a large amount of dust is generated inside the tunnel during the construction process and the operation of engineering machinery. Since the dust itself is light in weight and floats upward, the vacuum cleaner operation will cause the machine base to absorb the dust around itself in a wide range. The dust, impurities and some lighter harmful gases in the air flow to the dust suction pipe through the suction seat through the suction force of the vacuum cleaner, causing the suction seat to rotate, thereby boosting the flow speed of dust and impurities. At the same time, the bent bracket on the suction seat cleans the inner wall of the machine base to prevent excessive accumulation of dust, resulting in a reduction in the dust suction effect, and reducing the content of dust, smoke and mechanical exhaust pollution inside the tunnel, thereby improving the oxygen transportation environment in the oxygen generator, reducing the generation of harmful gases, and improving the personal safety factor of construction workers.

[0022] By setting up a blocking and dust cleaning component, using a pulley seat, an empty groove cone frame, a main wheel, a slave wheel, a toothed plate connecting seat, a rubber seal and a roller brush, the oxygen supply pipe is driven by a servo motor to slide at a uniform speed around the inside of the tunnel on the slide rail to transport oxygen, so as to achieve all-round oxygen supply, accurately identify the construction position of workers, and carry out fixed-point oxygen supply on the face to ensure the oxygen content inside the tunnel. At the same time, when the pulley seat passes through the dust absorption component, the rotation of the main wheel drives the slave wheel to make the rubber seal rise upward, and quickly block the output port of the oxygen supply pipe to avoid Prevent oxygen from being sucked out of the tunnel by the vacuum cleaner. At the same time, the blowing force of the oxygen delivery makes the concave fan-guided fan rotate, driving the roller brush to clean the inner wall at the bottom of the empty slot cone frame, avoiding the accumulation of dust and impurities inside the tunnel, which causes the oxygen delivery rate to decrease. At the same time, multiple groups of oxygen supply pipes carry out multi-directional reciprocating oxygen supply, which ensures the oxygen content inside the tunnel, avoids the incomplete combustion of construction machinery fuel, causes the generation of harmful gases, and avoids the hidden dangers to the personal safety of construction workers caused by insufficient oxygen content in the high-altitude and cold environment.

[0023] By setting up a vibration adjustment component and utilizing a rotating shaft gear, a crankshaft, a sliding rod, a slide seat, a fixed rod and a hammer head, when the sealing and dust cleaning component passes by, a two-way vibration is generated, so that the hammer head hammers the dust absorption component and vibrates the sealing and dust cleaning component at the same time, thereby ensuring the internal environment of oxygen supply and dust collection, while avoiding the blockage of the oxygen supply pipe and the dust collection pipe by dust and impurities, ensuring the delivery speed of oxygen and dust collection, creating favorable conditions for the construction environment, increasing the oxygen content inside the tunnel, and maximizing the combustion of mechanical fuel, avoiding the generation of harmful gases, ensuring the personal health of personnel, while improving the operating efficiency of personnel and machinery and accelerating the progress of construction.

The bent section surface of the bent bracket fits the bottom inner wall of the machine base 62. When the suction seat 64 absorbs the dust and impurities in the tunnel body 12, the suction force causes the fan inside the suction seat 64 to rotate slowly. While the fan rotates, it drives the bent bracket to start cleaning the inner wall at the bottom of the machine base 62. At the same time, the dust and impurities are transported to the inner cavity of the machine base 62, and then transported to the dust suction pipe 61 through the machine base 62, and then to the inside of the vacuum cleaner 3. After filtering, the impurities are transported to the dust collecting bin 4 for unified storage for subsequent processing, and the rack 63 is fixed on the middle end seat surface of the machine base 62 to remain fixed.

[0045] As an implementation method in this embodiment, Figures 7 to 10As shown, the blocking dust cleaning assembly 7 includes a pulley seat 71, which is slidably connected to the inside of the slide rail 11, and an empty groove cone frame 72 is installed at one end of the pulley seat 71. A main wheel 73 is installed on the top side of the empty groove cone frame 72. The main wheel 73 is meshed with the rack 1 63 on the motion track, and a rack 2 76 is installed on the top inner wall of the empty groove cone frame 72. One side of the main wheel 73 is meshed with a slave wheel 74, and the bottom of the slave wheel 74 is meshed with a double-headed wheel 77. The other end of the double-headed wheel 77 is meshed with A toothed plate connection seat 78 is connected, and the vertical distance of the gear teeth of the toothed plate connection seat 78 is consistent with the horizontal distance of the gear teeth of the rack 2 76.

The bottom of the rubber seal 79 is rotatably connected to a guide fan 710. A roller brush 711 is installed at one end of the guide fan 710. The surface of the roller brush 711 fits the inner wall of the bottom end of the machine base 62. When the oxygen supply pipe 75 continues to supply oxygen, When the concave fan guide 710 is acted upon by the blowing force, it rotates. When the fan guide 710 rotates, the roller brush 711 is closely attached to the bottom inner wall of the empty slot cone frame 72 for cleaning. At the same time, the pulley seat 71 starts to slide inside the slide rail 11. When the pulley seat 71 slides, it drives the empty slot cone frame 72 to move. When the empty slot cone frame 72 moves, it drives the oxygen delivery pipe 75 to move. At the same time, the multiple groups of empty slot cone frames 72 connected to the oxygen delivery pipe 75 slide one by one. When the empty slot cone frame 72 is moved, the oxygen delivery pipe 75 is moved. When the main wheel 73 moves to the dust absorption assembly 6, the main wheel 73 and the rack 1 63 start to mesh, and the main wheel 73 rotates, driving the slave wheel 74 to rotate synchronously. When the slave wheel 74 rotates, the double-headed wheel 77 meshingly connected at the other end starts to rotate, driving the toothed plate connecting seat 78 meshingly connected at the other end to start to move upward. When the toothed plate connecting seat 78 moves upward, the rubber seal 79 moves upward and stops at the output port of the oxygen delivery pipe 75. The rack 2 76 is fixed to the inner wall of the hollow groove cone frame 72.

[0046] As an implementation method in this embodiment, Figures 7 and 8As shown, the vibration adjustment component 8 includes a rotating shaft gear 81, which is mounted on the top of the rack 1 63, and the rotating shaft gear 81 is mounted on the motion trajectory of the rack 2 76. A crankshaft 82 is mounted on the top of the rotating shaft gear 81, and a sliding rod 83 is rotatably connected to the top of one end of the crankshaft 82.

A hammer head 86 is provided on one side of the sliding groove seat 84, and a spring is connected to one end of the hammer head 86 and the sliding groove seat 84. A fixing rod 85 is mounted on one end of the hammer head 86, and the fixing rod 85 is connected to the other end of the sliding rod 83. On the same motion trajectory, when the rack 2 76 is meshed and connected with the shaft gear 81, the shaft gear 81 is driven to rotate, and the crankshaft 82 is rotated at the same time. When the crankshaft 82 rotates, the slide bar 83 with one end rotatingly connected moves and slides inside the slide slot seat 84. When the slide bar 83 moves, the front end hits one end of the fixed rod 85. When the fixed rod 85 is hit, the hammer head 86 connected at the other end moves, and is affected by the spring connection between the slide slot seat 84 and the hammer head 86, so that it moves quickly and hits the machine base 62.

[0047] As an implementation method in this embodiment, Fig.11 As shown, the cabin oxygen generator 1, the vacuum cleaner 3, the servo motor 15 and the oxygen content detector 10 are all electrically connected to the control center 2.

[0048] The working principle provided by the technical solution of the present invention is that the cabin oxygen concentrator 1 is first transported to the outer end of the cave entrance far away from the tunnel body 12 for placement, ensuring that the device is parallel to the plateau ground to avoid tilting of the cabin oxygen concentrator 1, affecting the wear of internal mechanical parts and reducing the service life of the equipment. Then the diffusion tube 5 is connected to ensure that the diffusion tube 5 extends to the construction position of the tunnel face inside the tunnel body 12 and stops. The slide rail 11 is moved to the construction position by the gravity lifting vehicle 9, and the height is adjusted to be the same as the diffusion tube 5 and then stopped. The oxygen guide pipe 14 is connected to the output port of the diffusion pipe 5, and the side wall of the front end of the oxygen guide pipe 14 is in contact with the oxygen storage box 13. The control center 2 is started, and the oxygen content detector 10 is operated by the control center 2. The oxygen content inside the tunnel body 12 is detected, and the data is fed back to the control center 2. The cabin oxygen generator 1, the vacuum cleaner 3, the servo motor 15, the pulley seat 71 and the oxygen content detector 10 are started through the control center 2. When the vacuum cleaner 3 is in operation, the dust absorption component 6 starts to operate, and the dust and impurities in the tunnel body 12 are absorbed through the suction seat 64. The suction force causes the fan inside the suction seat 64 to rotate slowly. While the fan is rotating, it drives the bending bracket to start cleaning the inner wall at the bottom of the base 62 to avoid the accumulation of dust and impurities inside, resulting in a reduction in the dust collection effect. At the same time, the dust and impurities are transported to the inner cavity of the base 62, and then transported to the dust pipe 61 through the base 62, and then to the inside of the vacuum cleaner 3. After filtering, impurities The dust is transported to the dust collecting bin 4 for unified storage to facilitate subsequent processing. The rack 63 is fixed to the middle end seat surface of the machine base 62 and remains fixed. At the same time, the filtered harmless gas is discharged into the air outside the tunnel body 12. When the servo motor 15 is operating, the dust-blocking cleaning component 7 is operating. While the oxygen supply pipe 75 continues to supply oxygen, the concave fan guide 710 is rotated by the blowing force. When the fan guide 710 rotates, the roller brush 711 is close to the bottom inner wall of the empty slot cone frame 72 for cleaning. At the same time, the pulley seat 71 starts to slide inside the slide rail 11. When the pulley seat 71 slides, it drives the empty slot cone frame 72 to move. When the empty slot cone frame 72 moves, it drives the oxygen supply pipe 75 to move. At the same time, the oxygen supply pipe 75 The connected multiple groups of empty slot cone frames 72 slide one by one. When the empty slot cone frame 72 moves to the dust absorption component 6, the main wheel 73 starts to mesh with the rack 1 63, and the main wheel 73 rotates, driving the slave wheel 74 to rotate synchronously. When the slave wheel 74 rotates, the double-headed wheel 77 meshing at the other end starts to rotate, driving the toothed plate connecting seat 78 meshing at the other end to start moving upward. When the toothed plate connecting seat 78 moves upward, the rubber seal 79 moves upward to block the output port of the oxygen supply pipe 75 and stop. At the same time, the rack 2 76 is fixed to the inner wall of the empty slot cone frame 72 and moves with it to avoid the accumulation of dust and impurities inside the tunnel, which causes a decrease in the oxygen supply speed. At the same time, the oxygen supply pipe 75 performs multi-directional reciprocating oxygen supply through the servo motor 15.The oxygen content inside the tunnel body 12 is guaranteed, and the generation of harmful gases caused by insufficient combustion of fuel is avoided. At the same time, the hidden dangers to the personal safety of construction workers caused by insufficient oxygen content are avoided. When the dust-blocking and cleaning component 7 moves to the position of the dust-absorbing component 6, the rack 2 76 is meshed and connected with the rotating shaft gear 81 to drive the rotation. When the rotating shaft gear 81 rotates, it drives the crankshaft 82 to rotate. At the same time, when the crankshaft 82 rotates, the sliding rod 83 connected at one end rotates and moves at the same time, and slides inside the slide seat 84. When the sliding rod 83 moves, the front end hits one end of the fixed rod 85. When the fixed rod 85 is hit, the hammer head 86 connected at the other end moves. In addition, the spring connection between the slide seat 84 and the hammer head 86 causes it to move quickly and hit the machine base 62. At the same time, under the influence of vibration, the reaction force is fed back to the rack 2 76, causing the dust blocking component 7 to vibrate continuously, avoiding dust and impurities from blocking the oxygen supply pipe 75 and the dust suction pipe 61, ensuring the delivery speed of oxygen and dust suction, creating favorable conditions for the construction environment, reducing impurities and dust inside the tunnel, and increasing the oxygen content inside the tunnel. At the same time, the combustion of mechanical fuel is maximized, avoiding the generation of harmful gases, ensuring the personal health of personnel, and improving the operating efficiency of personnel and machinery, speeding up the construction process.
