Description

Technical Field

[0002] Reasonable underground ventilation is the basis for ensuring production safety in mining operations, and underground dampers and windows are key basic ventilation facilities in the ventilation system.

DETAILED DESCRIPTION

[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] In the present disclosure, unless otherwise stated, directional words such as "inside" and "outside" refer to the inside and outside of the relevant parts relative to their own contours in actual use, and "far" and "near" refer to the relative distance changes between any parts, such as Figure 1 When a pedestrian needs to pass through the air door assembly, the movement toward any air door is called approaching, and the movement away from any air door is called moving away. The same pedestrian can simultaneously move toward one of the air doors and away from the other air door between any two adjacent air doors.

[0025] In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have order or importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] The present disclosure provides a pneumatic assembly system for a downhole damper, referring to Figures 1 to 5The pneumatic assembly system includes a damper assembly 100 , a monitoring unit 200 , a control unit 300 and a voltage stabilizing unit 400 . Among them, the damper assembly 100 may include at least two groups of dampers, and any two groups of dampers may be arranged at intervals in the tunnel to separate the tunnel into a constant pressure area 150 and a variable pressure area, and the constant pressure area 150 is the area between the dampers, the monitoring unit 200 may include an air pressure monitoring device 210 arranged on the side walls of the tunnel in the constant pressure area 150 and the variable pressure area, which can be used to monitor the corresponding constant pressure area 150 and the air pressure information in the variable pressure area, a control unit 300 is arranged in the damper assembly 100, the control unit 300 is connected to the monitoring unit 200, and the damper assembly 100 can be controlled to open or close according to the monitoring signal of the monitoring unit 200, and the pneumatic assembly system also has a pressure stabilizing unit 400 arranged in the damper assembly 100, the pressure stabilizing unit 400 can be connected to the monitoring unit 200 and the control unit 300 respectively, and is used to drive the damper assembly 100 to open or close according to the monitoring signal of the air pressure monitoring device 210.

[0027] In the above embodiment, the multiple dampers in the damper assembly 100 can divide the alley into multiple areas. Since different air pressures are formed between the multiple areas after being blocked by the dampers, when the damper needs to be opened, the air pressure difference between the areas on both sides of the damper will affect the difficulty of opening and the switching speed of the damper. After obtaining the air pressure information of each area through the air pressure monitoring device 210 in the monitoring unit 200, pressure compensation is provided to the damper assembly 100 through the voltage stabilizing unit 400 to balance the influence of the pressure difference on the two sides of the damper assembly 100, thereby ensuring that the damper can be opened normally and making the opening and closing actions smooth, reducing collision damage to the damper assembly 100, and avoiding affecting the air tightness of the damper assembly 100.

[0028] Through the above technical solution, the pressure stabilizing unit 400 in the pneumatic assembly system can provide a certain pressure compensation to the damper assembly 100 after the monitoring unit 200 obtains the air pressure information of each area in the tunnel, so as to balance the pressure difference between the adjacent two side areas of the damper assembly 100, ensure that the switching action of the damper assembly 100 is smooth and stable, avoid damage to the damper assembly 100, increase the overall service life of the equipment, and ensure a reliable and safe underground working environment.

[0029] In some embodiments, reference Figures 1 to 5 The damper assembly 100 may include a first damper 110 and a second damper 120. The first damper 110 may be disposed near the air inlet of the lane, and the second damper 120 may be disposed near the air outlet of the lane, and the first damper 110 may include a first door leaf 111 and a second door leaf 112 which are reverse switches, and the second damper 120 may include a third door leaf 121 and a fourth door leaf 122 which are reverse switches.

[0030] In the above embodiment, the damper assembly 100 may have only two dampers, and the first damper 110 and the second damper 120 are arranged at intervals to form a constant pressure area 150, which can be formed as a buffer zone between the air inlet and the air outlet of the tunnel to slow down the air flow velocity between the air inlet and the air outlet, and avoid air flow fluctuations causing changes in the air pressure of the underground working environment, thereby affecting the health and safety of the workers. At the same time, setting the first damper 110 and the second damper 120 as two door leaves with reverse switches can slow down the flow rate of the airflow through the damper while facilitating the passage of pedestrians, avoiding the damper opening too quickly to cause a drastic change in air pressure or closing too quickly to cause physical damage to its own structure, thereby improving the safety and life of the damper assembly 100.

[0031] In this embodiment, multiple groups of dampers arranged at intervals can also be used to form a pneumatic assembly system. When the tunnel is a tortuous curve or has a long span, multiple groups of dampers can divide the tunnel into regions of different spatial volumes, so that the multiple constant pressure regions 150 formed can buffer the airflow between the air inlet and the air outlet in stages, thereby improving the air tightness between the tunnels and ensuring the safety of the underground working environment. Those skilled in the art can select the number of dampers according to the needs of the actual working environment, which will not be elaborated here.

[0032] For example, refer to Figure 1 , the voltage conversion area may include a first voltage conversion area 130 and a second voltage conversion area 140. The first voltage conversion area 130 may be located between the first damper 110 and the air inlet, the second voltage conversion area 140 may be located between the second damper 120 and the air outlet, and the constant pressure area 150 may be located in the area between the first damper 110 and the second damper 120. The airflow entering the underground from the air inlet may be blocked and regulated by the first damper 110, the constant pressure area 150 and the second damper 120 in sequence, so as to ensure the stability of the air pressure in the second voltage conversion area 140 and the underground working environment, and improve the personal health and safety of underground workers.

[0033] For example, refer to Figures 1 to 5 The control unit 300 may include a button box 310, a drive circuit 320 and an air valve box 330. There may be multiple button boxes 310, and the multiple button boxes 310 may be respectively arranged on the side of the first damper 110 facing the air inlet and the side of the second damper 120 facing the air outlet. The drive circuit 320 can be used to control the opening and closing of the first damper 110 and the second damper 120, wherein the button box 310 can be connected to the drive circuit 320 through the air valve box 330, and the air valve box 330 can control the drive circuit 320 to drive the first damper 110 and the second damper 120 to open and close according to the instructions of the button box 310, and the first damper 110 and the second damper 120 are selectively opened.

[0034] In the above embodiment, the button box 310 is an external starting element. The staff can press the command key on the button box 310 and operate the valve box 330 to control the drive circuit 320, so that the drive circuit 320 can drive the first damper 110 and the second damper 120 to open or close. Among them, the first damper 110 and the second damper 120 are set to be opened one by one to avoid that the first damper 110 and the second damper 120 are both in the open state at the same time, and the air pressure between different areas will cause the air flow rate to be too fast and difficult to control. The first damper 110 and the second damper 120 that are opened one by one can always keep the lane from being connected to form a passage. The constant pressure area 150 can be used as a buffer zone to keep the air pressure in the lane stable, which can effectively avoid the drastic changes in air pressure caused by the above situation.

[0035] For example, refer to Figures 2 to 4 The driving circuit 320 may include a first driving cylinder 321, a second driving cylinder 323, a first interlocking rod 322, and a second interlocking rod 324. One end of the first driving cylinder 321 may be hinged to the middle of the door frame of the first damper 110, and the other end may be connected to the first door leaf 111 or the second door leaf 112, so that one of the door leaves of the first damper 110 can be rotated and opened and closed under the drive of the first driving cylinder 321, and the first door leaf 111 and the second door leaf 112 are connected through the first interlocking rod 322, and the first interlocking rod 322 and the first driving cylinder 321 are respectively placed on both sides of the first damper 110, so that when the active door leaf of the first damper 110 with the first driving cylinder 321 rotates, the other passive door leaf is driven to rotate synchronously in the opposite direction through the first interlocking rod 322, and the rotation amplitudes of the two are consistent. When any door leaf needs to remain stationary, the rotational movement between the two door leaves is mutually locked by the first interlocking rod 322, and the two door leaves can remain stationary at the current position at the same time, facilitating the passage of pedestrians, goods or other equipment.

[0036] In the embodiment of the present disclosure, the connection method and driving principle between the first drive cylinder 321, the first interlocking rod 322 and the first damper 110 are the same as the connection method and driving principle between the second drive cylinder 323, the second interlocking rod 324 and the second damper 120. By describing the connection relationship between the above-mentioned first drive cylinder 321, the first interlocking rod 322 and the first damper 110, the connection relationship between the second drive cylinder 323, the second interlocking rod 324 and the second damper 120 can be fully understood, which is not repeated here.

[0037] In other embodiments, the first interlocking rod 322 and the second interlocking rod 324 can be telescopic rods, which can be used to adjust the opening and closing amplitudes of two door leaves in the same group, and are locked after adjustment to avoid failure of mutual locking between the two door leaves. The locked first interlocking rod 322 and the second interlocking rod 324 are equivalent to straight rods whose lengths will not change, thereby effectively ensuring the interlocking strength and switching safety between the two door leaves.

[0038] For example, refer to Figures 2 to 4 , the end of the first driving cylinder 321 connected to the first door leaf 111 or the second door leaf 112 may be provided with a first mounting seat 3211, the first driving cylinder 321 and the first mounting seat 3211 may be hinged, the first interlocking pull rod 322 may be hinged to the first door leaf 111 through a third mounting seat 3221, and may be hinged to the second door leaf 112 through a fourth mounting seat 3222. In contrast, the end of the second driving cylinder 323 connected to the third door leaf 121 or the fourth door leaf 122) may be provided with a second mounting seat 3231, the second driving cylinder 323 and the second mounting seat 3231 may be hinged, the second interlocking pull rod 324 may be hinged to the third door leaf 121 through a fifth mounting seat 3241, and may be hinged to the fourth door leaf 122 through a sixth mounting seat 3242. In this embodiment, one end of the first mounting seat 3211 is fixed to the panel surface of the door leaf, and the other end is hinged to one end of the first driving cylinder 321. The connection between the two allows relative rotation between the two. Similarly, the second mounting seat 3231, the third mounting seat 3221 and the fourth mounting seat 3222 can also be set to the structure and connection method of the first mounting seat 3211 to ensure that the various components connected through the mounting seat structure have rotational freedom and stable and reliable connection.

[0039] For example, refer to Figure 1 and Figure 5The pressure stabilizing unit 400 may include a first air bag 410, a first barometer 420, and a first valve island 430. The first air bag 410 may be connected to the first damper 110 through the first driving cylinder 321, and is used to supplement or extract gas from the first driving cylinder 321 for pressure compensation. The first barometer 420 may be connected to the first driving cylinder 321, and is used to detect and display the cylinder pressure of the first driving cylinder 321. The first valve island 430 may be connected between the first air bag 410 and the first driving cylinder 321, and is used to control the connection or disconnection of the first air bag 410 and the first driving cylinder 321 according to the detection data of the first barometer 420. In this embodiment, the first air bag 410 can be used to connect and disconnect with the first drive cylinder 321 under the control of the first valve island 430. Specifically, a corresponding connection method can be adopted according to the cylinder pressure of the first drive cylinder 321 measured by the first barometer 420. When the first air bag 410 is connected to the first drive cylinder 321, gas can be added to the first drive cylinder 321 to increase the output of the first drive cylinder 321, or gas can be extracted from the first drive cylinder 321 to reduce the output of the first drive cylinder 321. It can be used to adjust to the actual opening and closing output requirements of the first damper 110.

[0040] In some embodiments, reference Figures 1 to 5 , the first valve island 430 can be configured to control the first air bag 410 to communicate with the first driving cylinder 321 when the air pressure monitoring device 210 detects that the air pressure in the first variable pressure area 130 is greater than the air pressure in the constant pressure area 150, and can control the first air bag 410 to output air pressure to the first driving cylinder 321 to balance the air pressure in the first variable pressure area 130. The air pressure balance here means that the air pressure in the cylinder of the first driving cylinder 321 after being supplemented by the first air bag 410 can balance the pressure difference between the first variable pressure area 130 and the constant pressure area 150, so that the first driving cylinder 321 overcomes the air pressure resistance of the first variable pressure area 130 and stably opens the first damper 110, and the air pressure in the cylinder of the first driving cylinder 321 can be detected and monitored by the first barometer 420.

[0041] In other embodiments, when the air pressure monitoring device 210 detects that the air pressure in the first variable pressure area 130 is equal to the constant pressure area 150, it is not necessary to use the first air bag 410 to regulate the cylinder pressure of the first drive cylinder 321. The first valve island 430 can disconnect the first air bag 410 from the first drive cylinder 321 so that the first drive cylinder 321 can switch the first damper 110 through the preset output.

[0042] In other embodiments, when the air pressure monitoring device 210 detects that the air pressure in the first variable pressure area 130 is lower than that in the constant pressure area 150, the first valve island 430 may connect the first air bag 410 with the first driving cylinder 321, and control the first air bag 410 to extract gas from the first driving cylinder 321 to reduce the output of the first driving cylinder 321, thereby preventing the first driving cylinder 321 from opening and closing the first damper 110 too quickly at a preset output, causing excessive pressure changes between the first variable pressure area 130 and the constant pressure area 150, or causing severe collisions between the first door leaf 111 and the second door leaf 112 and the first damper 110, resulting in damage and reducing the service life of the first damper 110.

[0043] For example, refer to Figures 1 to 5 The pressure stabilizing unit 400 may further include a second air bag 440, a second barometer 450, and a second valve island 460. The second air bag 440 may be connected to the second damper 120 via the second driving cylinder 323, and is used to supplement or extract gas from the second driving cylinder 323 for pressure compensation. The second barometer 450 may be connected to the second driving cylinder 323 to detect and display the cylinder pressure of the second driving cylinder 323. The second valve island 460 may be connected between the second air bag 440 and the second driving cylinder 323, and is used to control the connection or disconnection between the second air bag 440 and the second driving cylinder 323 according to the detection data of the second barometer 450. With reference to the structural connection and functional principles among the aforementioned first air bag 410, the first pressure gauge 420, the first valve island 430 and the first damper 110, it can be understood that the second air bag 440, the second pressure gauge 450, the second valve island 460 and the second damper 120 may also function in the same or similar manner as described above, which will not be elaborated herein.

[0044] For example, refer to Figures 1 to 5 The second valve island 460 can be configured to control the second air bag 440 to communicate with the second drive cylinder 323 when the air pressure monitoring device 210 detects that the air pressure in the second variable pressure area 140 is greater than the air pressure in the constant pressure area 150, and can control the second air bag 440 to output air pressure to the second drive cylinder 323 so that the cylinder pressure is balanced with the air pressure in the second variable pressure area 140. The air pressure balance here is similar to the air pressure balance between the first drive cylinder 321 and the first variable pressure area 130 mentioned above. It can be understood that the second air bag 440 can provide air pressure compensation to the second drive cylinder 323 so that the cylinder pressure of the second drive cylinder 323 can balance the pressure difference between the second variable pressure area 140 and the constant pressure area 150, so as to ensure that the second damper 120 can overcome the air pressure resistance of the second variable pressure area 140 and open stably. The second barometer 450 can be used to detect the cylinder pressure of the second drive cylinder 323 so as to adjust the output of the second drive cylinder 323.

[0045] In other embodiments, the second air bag 440 can also be connected or disconnected with the second drive cylinder 323 under the control of the second valve island 460 according to the pressure difference change between the second variable pressure area 140 and the constant pressure area 150. The specific on-off logic can refer to the control method between the above-mentioned first air bag 410, the first air pressure gauge 420, and the first valve island 430 and the first damper 110. The two have the same or similar function and will not be elaborated here.

[0046] In other embodiments, reference Figure 1 The monitoring unit 200 may also include a human portrait monitoring sensor 220 for monitoring the area range close to the damper assembly 100. The human portrait monitoring sensor 220 may be configured to control the control unit 300 to open the corresponding damper when it detects that a pedestrian is close to the area range of any damper of the damper assembly 100, and to control the control unit 300 to close the corresponding damper when it detects that a pedestrian is leaving the area range of any damper of the damper assembly 100. In this embodiment, the human portrait monitoring sensor 220 may be a human portrait recognition camera or an infrared sensor or other device, and may be arranged on the top of the door frame of the damper assembly 100 or on the side wall of the lane, with no obstruction between the human portrait monitoring sensor 220 and the monitored area, so as to clearly obtain whether the pedestrian's movement direction is close to or away from the damper assembly 100, and to open the damper when the pedestrian approaches and close the damper when the pedestrian leaves, so as to increase the automation of the damper and improve the overall convenience of the system. At the same time, this method of controlling the damper switch through the monitoring unit 200 can be independent of the above-mentioned method of controlling the damper switch using the button box 310, so that when damage or abnormality occurs in either method, the damper assembly 100 can be normally controlled by another method, thereby improving the fault tolerance and adaptability of the system.
