Description

Technical Field

[0001] This invention relates to the field of underground miners' safety cleaning equipment technology, specifically to a mechanically triggered spray and atomizing nozzle self-protecting underground miners' cleaning tunnel. Background Technology

[0002] Underground working environments are harsh, requiring miners to wear protective suits, helmets, and masks for extended periods in mines with extremely high dust concentrations (such as coal mines and metal mines). After work, miners must pass through specialized cleaning tunnels to remove dust adhering to their bodies (especially the surface, cuffs, and collar of their protective suits) to prevent bringing high concentrations of dust to the surface environment and to protect their own health.

[0003] Existing cleaning tunnels typically include the following components: Main structure: The tunnel body has an entrance at the front and an exit at the rear. Miners enter through the entrance, are sprayed and cleaned, and then leave through the exit. Spraying mechanism: Installed inside the tunnel body, it is supplied with water by a water tank and pump outside the tunnel. High-pressure water jets or water mists are sprayed onto the miners through atomizing nozzles to wash away dust from their bodies. Trigger control: It relies on infrared sensors to detect whether someone has entered the tunnel. When the sensor detects a human signal, it automatically starts the water pump to supply water; when no one is present, the water pump is turned off to conserve resources.

[0004] However, the above technologies generally have the following problems in practical downhole applications: Infrared sensors suffer from poor reliability and high maintenance costs: The underground environment contains a large amount of fine dust (such as coal dust and rock dust), which easily adheres to the lens or transmitting / receiving window of the infrared sensor, causing light (or infrared radiation) transmission to be blocked and the sensor to misjudge. In addition, infrared sensors are precision electronic components that not only require regular positioning and maintenance (such as cleaning the lens and calibrating the sensitivity), but their structure is also fragile (easily damaged by moisture, vibration or dust particle impact). Once a fault occurs, it needs to be replaced by professionals, resulting in high maintenance costs and seriously affecting the normal operating efficiency of the cleaning tunnel. Dust is not thoroughly cleaned from the bottom of miners' arms: Existing tunnel cleaning relies on fixed spray systems to spray water all over miners' bodies. However, after entering the tunnel, miners usually let their arms hang down naturally or only swing them slightly due to habit or the desire to save effort, and do not actively raise them (especially the cuffs, the inside of the forearms, etc.). This means that the dust on the bottom of the arms and the inside of the cuffs cannot be directly washed away. Over time, this may become a "dead zone" for dust residue, reducing the cleaning effect. Dust can easily enter and clog atomizing nozzles in the tunnel: Since the entrance and exit of the main tunnel are directly connected to the high-dust environment underground, when miners enter or leave, the high concentration of dust from the outside will be carried into the tunnel along with the movement of the miners. This dust can easily accumulate at the nozzles of the atomizing nozzles, gradually clogging the nozzles and causing uneven dispersion of the spray water (or even failure to spray), which seriously affects the cleaning effect. Summary of the Invention

[0005] The first technical problem this invention aims to solve is to provide a mechanically triggered spray and atomizing nozzle self-protective underground miner cleaning tunnel. By replacing infrared detection with mechanical triggering and using a self-protective design that forces the double arms to extend, the reliability and cleaning effect of the cleaning tunnel are comprehensively improved, solving the problems of easy failure of infrared sensors and difficulty in cleaning dust at the bottom of miners' double arms in existing cleaning tunnels.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A self-protected underground miner cleaning tunnel with mechanically triggered spray and atomizing nozzles includes a tunnel body with an entrance at the front and an exit at the rear. A spray mechanism is installed inside the tunnel body, and the spray mechanism is supplied with water by a water tank and a water pump outside the tunnel body. The core improvement lies in the following: two elastically set and independent mechanical triggering mechanisms are installed on the left and right inner walls of the tunnel body, and receiving switch assemblies electrically controlled by the water pump and used in conjunction with the mechanical triggering mechanisms are installed on the left and right outer walls of the tunnel body. When a miner enters the spray mechanism inside the tunnel body, the miner extends his arms to the sides and pushes the mechanical triggering mechanisms on both sides with his hands. The mechanical triggering mechanisms then actuate the receiving switch assemblies and start the water pump to achieve spraying.

[0007] By adopting the above solution, mechanical triggering (manual push) is used during cleaning to replace the easily damaged infrared sensor, avoiding detection errors caused by dust interference and improving triggering reliability (no risk of electronic component damage, maintenance only requires checking mechanical parts). This mechanical structure is low in cost and has a long service life. Secondly, the dual-arm independent push design conforms to the natural human movement. When the miner actively extends his arms, the spray is triggered simultaneously, eliminating traditional dead corners such as cuffs and inner forearms, and making dust removal more thorough.

[0008] As a preferred embodiment of a mechanically triggered spray and atomizing nozzle self-protection type underground miner cleaning tunnel, the mechanical triggering mechanism includes a trigger rod extending from inside the tunnel body to outside the tunnel body. The trigger rod is reset inside the tunnel body by a return spring. The trigger rod can automatically reset (by the return spring) after the miner releases his hand, making it convenient for the next miner to use without having to manually restore the initial state.

[0009] As a preferred embodiment of a mechanically triggered spray and atomizing nozzle self-protection type underground miner cleaning tunnel, the receiving switch assembly includes a mounting base fixedly connected to the tunnel body and a receiving button fixed on the mounting base, wherein the receiving button and the trigger rod are located on the same straight line; the trigger rod and the receiving button are coaxially aligned to ensure direct transmission of thrust (avoiding trigger failure due to skewness), and high trigger sensitivity; when the trigger rod is pushed outward, its end can contact the receiving button and start the water pump; when the trigger rod is released, its end separates from the receiving button and shuts off the water pump; the start and stop of the water pump are strictly synchronized with the push / release state of the trigger rod (push → start, release → stop), accurately controlling the spraying time and saving water resources.

[0010] As a preferred embodiment of a mechanically triggered spray and atomizing nozzle self-protection type underground miner cleaning tunnel, a trigger balloon is fixed at the end of the trigger rod, which is in direct contact with the receiving button. The trigger balloon is filled with air at a pressure greater than or equal to the external air pressure to keep it in an inflated state. The flexible material (such as rubber) of the trigger balloon can buffer the hard collision between the trigger rod and the receiving button, preventing damage to both due to excessive impact force. Secondly, the inflated balloon increases the contact area, ensuring uniform transmission of thrust (stable triggering even if the trigger rod is slightly deflected), thus improving triggering stability.

[0011] As a preferred embodiment of a mechanically triggered spray and atomizing nozzle self-protection type underground miner cleaning tunnel, the spray mechanism includes a side atomizing nozzle located below, a top atomizing nozzle located directly above the side atomizing nozzle and tilted downwards, and a water pipe connecting the side atomizing nozzle and the top atomizing nozzle and spraying water into them; the side + top combined nozzle achieves multi-angle coverage of the miner's whole body, improving cleaning efficiency; the tilted downward design of the top nozzle can focus on rinsing dust from high places such as the shoulders and neck, while the horizontal side nozzle can cover the waist to ankle area, forming an all-round cleaning.

[0012] The second technical problem to be solved by this invention is to provide a mechanically triggered spray and atomizing nozzle self-protection type for underground miner cleaning tunnels. Based on the mechanical triggering to replace infrared detection, the atomizing nozzle self-protection design is added to comprehensively improve the durability of the atomizing nozzle and solve the problem of dust clogging the atomizing nozzle in existing cleaning tunnels.

[0013] To achieve the above objectives, the present invention provides the following technical solution: Based on the above scheme, the mechanical triggering mechanism also includes multiple vertically arranged vertical rods corresponding to the locations of the top and bottom atomizing nozzles. A lower protective sleeve that can block the side atomizing nozzles is connected to the bottom of the vertical rod, and an upper protective sleeve that can block the top atomizing nozzle is connected to the bottom of the vertical rod. All vertical rods are slidably installed on guide rods fixed to the outer wall of the water pipe. All return springs are fitted on the guide rods and push the vertical rods to return to their original positions. A horizontal rod that simultaneously pushes all vertical rods is fixed to the body of each vertical rod. The trigger rod is connected to the body of the horizontal rod, and a handle is also connected to the horizontal rod.

[0014] By adopting the above scheme, when the spray is started (by pushing the crossbar), the lower and upper protective sleeves simultaneously disengage from the side / top atomizing nozzles, ensuring that the nozzles work normally; when the spray is stopped (by releasing the crossbar), the protective sleeves automatically reset to cover the nozzles, preventing dust in the tunnel from entering the nozzle holes and clogging the nozzles, thus extending the service life of the nozzles; the above multiple nozzles (side + top) share a set of protective structures, simplifying the design and ensuring good synchronization.

[0015] As a preferred embodiment of a mechanically triggered spray and atomizing nozzle self-protection type underground miner cleaning tunnel, the lower protective sleeve is coaxially mounted on the side atomizing nozzle, and the lower protective sleeve is directly fixedly connected to the bottom end of the vertical rod; the lower protective sleeve and the side atomizing nozzle are coaxially connected, which can cover the area around the nozzle when blocking, and there is no offset error when resetting (ensuring that the nozzle is fully exposed); its direct connection method has a simple structure, does not require additional transmission components, and is easy to maintain.

[0016] As a preferred embodiment of a mechanically triggered spray and atomizing nozzle self-protection type underground miner cleaning tunnel, the upper protective sleeve is coaxially mounted on the top atomizing nozzle. The upper protective sleeve is indirectly fixed to the bottom end of the vertical rod through a pulley system and a wire rope. The top atomizing nozzle is usually located at a high position (close to the top of the tunnel). Through the indirect connection of the pulley system and the wire rope, the horizontal movement of the vertical rod can be converted into the vertical movement of the upper protective sleeve (adapting to complex spatial layouts). The pulley system reduces frictional resistance and ensures smooth reset of the upper protective sleeve.

[0017] As a preferred embodiment of a mechanically triggered spray and atomizing nozzle self-protection type underground miner cleaning tunnel, the pulley block has two sets of pulleys, and the steel wire rope is wound in an S-shape on the two sets of pulleys, with the two ends of the steel wire rope connected to the top of the upper protective sleeve and the top of the vertical rod, respectively. The S-shaped winding method can amplify the pushing force of the vertical rod, while ensuring that the moving distance of the upper protective sleeve matches the displacement of the vertical rod (precisely blocking / exposing the nozzle). The two sets of pulleys distribute the force, extending the service life of the pulleys and steel wire rope.

[0018] As a preferred embodiment of a mechanically triggered spray and atomizing nozzle self-protection system for cleaning tunnels in underground mines, when the trigger rod is pushed outward, its end contacts the receiving button and starts the water pump, at which point the lower protective sleeve completely detaches from the obstruction of the atomizing nozzle on the side; when the trigger rod is released, its end separates from the receiving button and the water pump is turned off, at which point the lower protective sleeve returns to its original position and completely obstructs the atomizing nozzle on the side; thus, when the spray is on, the nozzle is unobstructed (maximum water flow), and when the spray is off, the nozzle is completely sealed (zero dust entry), balancing cleaning effectiveness and nozzle protection.

[0019] The beneficial effects of this invention are: 1. Significantly improved detection reliability: The mechanical trigger (manual push) replaces the easily damaged infrared sensor, avoiding detection errors caused by dust interference, thus improving trigger reliability (no risk of electronic component damage, maintenance only requires checking mechanical parts). This mechanical structure is low in cost and has a long service life. 2. Comprehensive optimization of washing effect: The independent propulsion design of the two arms conforms to the natural movement of the human body. When the miner actively extends his arms, the spray is triggered simultaneously, eliminating traditional dead corners such as cuffs and inner forearms, and removing dust more thoroughly. 3. Significantly enhanced nozzle durability: The protective cover completely blocks the nozzle inlet when not spraying, effectively preventing dust from entering the tunnel, avoiding nozzle blockage, extending nozzle lifespan, and reducing cleaning frequency; 4. Simple structure and low cost: The mechanical transmission components (such as trigger rods, vertical rods, return springs, etc.) are all conventional industrial parts, with low manufacturing and maintenance costs, and are suitable for harsh underground environments (vibration resistant, moisture resistant).

Detailed Implementation

[0023] The technical solutions of 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 2As shown, a self-protected underground miner cleaning tunnel with mechanically triggered spray and atomizing nozzles is provided. Specifically, it includes a tunnel body 1 with an entrance at the front and an exit at the rear. A spray mechanism 4 is installed inside the tunnel body 1, and the spray mechanism 4 is supplied with water through a water tank 2 and a water pump 3 outside the tunnel body 1. Mechanically triggered mechanisms 5 are elastically set and independent of each other on the left and right inner walls of the tunnel body 1. Receiving switch assemblies 6, which are electrically controlled by the water pump 3 and cooperate with the mechanically triggered mechanisms 5, are installed on the left and right outer walls of the tunnel body 1. When a miner enters the spray mechanism 4 inside the tunnel body 1, the miner extends his arms to the sides and pushes the mechanically triggered mechanisms 5 on both sides with his hands. The mechanically triggered mechanisms 5 then abut against the receiving switch assemblies 6 and start the water pump 3 to achieve spraying. During cleaning, a mechanical trigger (manual push) is used instead of the easily damaged infrared sensor, avoiding detection errors caused by dust interference and improving trigger reliability (no risk of electronic component damage, maintenance only requires checking mechanical parts). This mechanical structure is low in cost and has a long service life. Secondly, the independent dual-arm push design conforms to the natural human movement. When the miner actively extends his arms, the spray is triggered simultaneously, eliminating traditional dead corners such as cuffs and inner forearms, and removing dust more thoroughly.

[0025] like Figures 3 to 10 As shown, the mechanical triggering mechanism 5 includes a trigger rod 51 extending from inside the tunnel body 1 to outside the tunnel body 1. The trigger rod 51 is reset inside the tunnel body 1 by a reset spring 55. The trigger rod 51 can be automatically reset after the miner releases his hand (by the reset spring 55), making it convenient for the next miner to use without having to manually restore the initial state.

[0026] like Figures 3 to 10 As shown, the receiving switch assembly 6 includes a mounting base 61 fixedly connected to the tunnel body 1 and a receiving button 62 fixed on the mounting base 61. The receiving button 62 and the trigger rod 51 are located on the same straight line. The trigger rod 51 and the receiving button 62 are coaxially aligned to ensure direct transmission of thrust (avoiding trigger failure due to skewness) and high trigger sensitivity. When the trigger rod 51 is pushed outward, its end can contact the receiving button 62 and start the water pump 3. When the trigger rod 51 is released, its end separates from the receiving button 62 and shuts off the water pump 3. The start and stop of the water pump 3 are strictly synchronized with the push / release state of the trigger rod 51 (push → start, release → stop), accurately controlling the spraying time and saving water resources.

[0027] like Figures 3 to 10As shown, a trigger balloon 52 is fixed at the end of the trigger rod 51, which is in direct contact with the receiving button 62. The trigger balloon 52 is filled with air at a pressure greater than or equal to the external air pressure to make it inflated. The flexible material (such as rubber) of the trigger balloon 52 can buffer the hard collision between the trigger rod 51 and the receiving button 62, preventing damage to both due to excessive impact. Secondly, the inflated balloon increases the contact area, ensuring that the thrust is transmitted evenly (even if the trigger rod 51 is slightly deflected, it can still be triggered stably), thus improving the triggering stability.

[0028] like Figures 3 to 10 As shown, the spraying mechanism 4 includes a side atomizing nozzle 41 located below, a top atomizing nozzle 42 located directly above the side atomizing nozzle 41 and tilted downwards, and a water pipe 43 connecting the side atomizing nozzle 41 and the top atomizing nozzle 42 and spraying water onto them; the side + top combined nozzle achieves multi-angle coverage of the miner's whole body, improving cleaning efficiency; the tilted downward design of the top nozzle can focus on rinsing dust from high places such as the shoulders and neck, while the horizontal side nozzle can cover the area from the waist to the ankles, forming an all-round cleaning.

[0029] like Figures 3 to 10 As shown, the mechanical triggering mechanism 5 also includes multiple vertically arranged vertical rods 53 corresponding to the locations of the top atomizing nozzle 42 and the bottom atomizing nozzle. A lower protective sleeve 7, capable of shielding the side atomizing nozzle 41, is connected to the bottom end of each vertical rod 53, and an upper protective sleeve 8, capable of shielding the top atomizing nozzle 42, is connected to the bottom end of each vertical rod 53. All vertical rods 53 are slidably mounted on guide rods 54 fixed to the outer wall of the water pipe 43. All return springs 55 are fitted onto the guide rods 54 and push the vertical rods 53 to reset. A horizontal rod 56, which simultaneously pushes all vertical rods 53, is fixed to the body of each vertical rod 53. A trigger rod 51 is connected to the body of the horizontal rod 56, and a handle 57 is also connected to the horizontal rod 56. When the spraying starts (by pushing the horizontal rod 56), the lower protective sleeve 7 and the upper protective sleeve 8 simultaneously disengage from the side / top atomizing nozzles. The protective sleeve 7 shields the nozzle 42 to ensure its normal operation. When spraying stops (by releasing the crossbar 56), the protective sleeve automatically resets to shield the nozzle, preventing dust from entering the nozzle holes and clogging it, thus extending the nozzle's service life. Multiple nozzles (side + top) share a single protective structure, simplifying the design and ensuring good synchronization. When the trigger lever 51 is pushed outwards, its end contacts the receiving button 62 and starts the water pump 3, at which point the lower protective sleeve 7 completely disengages from shielding the side atomizing nozzle 41. When the trigger lever 51 is released, its end separates from the receiving button 62 and shuts off the water pump 3, at which point the lower protective sleeve 7 resets to completely shield the side atomizing nozzle 41. Therefore, when spraying is on, the nozzle is unobstructed (maximum water flow), and when spraying is off, the nozzle is completely sealed (zero dust entry), balancing cleaning effectiveness and nozzle protection.

[0030] like Figures 3 to 10As shown, the lower protective sleeve 7 is coaxially mounted on the side atomizing nozzle 41, and the lower protective sleeve 7 is directly fixedly connected to the bottom end of the vertical rod 53; the lower protective sleeve 7 is coaxially sleeved with the side atomizing nozzle 41, which can cover the area around the nozzle when blocking, and there is no offset error when resetting (ensuring that the nozzle is fully exposed); its direct connection method has a simple structure, does not require additional transmission parts, and is easy to maintain.

[0031] like Figures 3 to 10 As shown, the upper protective sleeve 8 is coaxially mounted on the top atomizing nozzle 42. The upper protective sleeve 8 is indirectly fixed to the bottom end of the vertical rod 53 through the pulley block 9 and the steel wire rope 10. The top atomizing nozzle 42 is usually located at a high position (close to the top of the tunnel). Through the indirect connection of the pulley block 9 and the steel wire rope 10, the horizontal movement of the vertical rod 53 can be converted into the vertical movement of the upper protective sleeve 8 (to adapt to complex spatial layouts). The pulley block 9 reduces frictional resistance and ensures that the upper protective sleeve 8 resets smoothly.

[0032] like Figures 3 to 10 As shown, the pulley block 9 has two sets of pulleys, and the wire rope 10 is wound in an S-shape around the two sets of pulleys. The two ends of the wire rope 10 are connected to the top of the upper protective sleeve 8 and the top of the vertical rod 53, respectively. The S-shaped winding method can amplify the pushing force of the vertical rod 53, while ensuring that the moving distance of the upper protective sleeve 8 matches the displacement of the vertical rod 53 (precisely blocking / exposing the nozzle). The two sets of pulleys distribute the force, extending the service life of the pulleys and the wire rope 10.

[0033] The working principle of this mechanically triggered spray and atomizing nozzle self-protective underground miner tunnel cleaning system: Initial state: When the miner has not entered the tunnel, the trigger rod 51 of the mechanical trigger mechanism 5 is located inside the tunnel body 1 under the action of the return spring 55, the receive button 62 of the receive switch assembly 6 is not touched, and the water pump 3 is in the off state; the vertical rod 53 is in the low position under the push of the return spring 55, the lower protective sleeve 7 completely covers the side atomizing nozzle 41, and the upper protective sleeve 8 indirectly covers the top atomizing nozzle 42 through the pulley group 9 and the wire rope 10. Figures 3 to 6 As shown; Triggering the spray: After the miner enters the tunnel, he spreads his arms to the left and right and pushes the handles 57 on both sides. The handles 57 and the horizontal bar 56 will drive the trigger rod 51 to move. The trigger rod 51 overcomes the resistance of the return spring 55 and moves outward. The trigger ball 52 at the end contacts the receiving button 62 of the receiving switch assembly 6, starting the water pump 3 to supply water. At the same time, the horizontal bar 56 will also drive all the vertical bars 53 to move. At this time, the lower protective sleeve detaches from the side atomizing nozzle 41, and the upper protective sleeve 8 detaches from the top atomizing nozzle 42 through the pulley group 9 and the wire rope 10. The spraying mechanism 4 begins to spray in all directions. Figures 7 to 10 As shown; Stop spraying: After the miners finish cleaning, they release handle 57. Under the action of return spring 55, trigger rod 51 retracts inward to the tunnel body 1, receiving button 62 separates from trigger balloon 52, and water pump 3 shuts off. At the same time, under the push of return spring 55, vertical rod 53, lower protective sleeve 7 completely covers the side atomizing nozzle 41 again, and upper protective sleeve 8, through pulley block 9 and wire rope 10, resets and covers the top atomizing nozzle 42, and the nozzle enters dustproof state. Figures 3 to 6 As shown.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
