Description

Technical Field

[0001] This invention relates to the field of mining technology, specifically to an underground ventilator that rapidly reduces the concentration of carbon monoxide inside a mine. Background Technology

[0002] Mining is one of the oldest fields in which humankind engages in productive labor. During the mining process, workers underground will continuously generate toxic and harmful gases, such as carbon monoxide, carbon dioxide, nitrogen dioxide, sulfur dioxide, hydrogen sulfide, and methane. If these gases are not removed, workers cannot survive. However, existing underground ventilators easily transport dust from the air into the mine, and they can only supply air in a fixed direction, making it impossible to change the direction of the airflow. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing an underground ventilator that can rapidly reduce the concentration of carbon monoxide inside a mine. This solves the problem mentioned in the background art that existing underground ventilators easily transport dust from the air into the mine during operation, and that existing underground ventilators can only supply air in a fixed direction and cannot change the direction of the airflow.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an underground ventilator for rapidly reducing the concentration of carbon monoxide inside a mine, comprising a base structure as a movable support, wherein the base structure is provided with a swinging structure that allows the air supply and filtration structure to move left and right under force.

[0005] The base structure includes a base plate with a mounting groove at the bottom, and symmetrically arranged movable wheels at the bottom of the base plate to move the overall structure to different workplaces. The movable wheels are connected by first hydraulic telescopic cylinders symmetrically arranged at the bottom of the base plate to adjust the load-bearing plate up and down. The load-bearing plate has multiple ground nails for support and limiting.

[0006] By adopting the above technical solution, the ground nails can achieve the effects of force adjustment and ground insertion limit.

[0007] Preferably, the base structure includes a base plate with a mounting groove at the bottom, a limiting plate on one side above the base plate for limiting the connection of the swing structure, and a counterweight on the limiting plate to maintain the overall balance and stability of the equipment.

[0008] By adopting the above technical solution, the counterweight can achieve a balanced and stable effect on the overall equipment.

[0009] Preferably, the swing structure includes a push block with a groove at the bottom, and the push block is movably positioned above the base plate via a matching block and a second hydraulic telescopic cylinder.

[0010] By adopting the above technical solution, the push block can be adjusted to limit the force through the matching block.

[0011] Preferably, the swing structure includes a matching block, the matching block is provided with an adjustment disc for rotation adjustment via a limiting rod, a driving plate for force adjustment is provided on one side of the adjustment disc, a threaded sleeve with a through hole is provided on one side of the driving plate, and an elastic rope for elastic recovery of the driving plate is provided on the threaded sleeve via a fixing bolt.

[0012] By adopting the above technical solution, the force swing adjustment effect of the drive plate and air supply filter structure can be achieved by adjusting the adjustment plate.

[0013] Preferably, the air supply and filtration structure includes an air supply support assembly for installing the filtration component. The air supply support assembly includes a water tank with a high-pressure water pump installed inside. The water tank is mounted on an adjustment plate and a drive plate via an installation platform. A fan for supplying air into the mine is installed on the installation platform.

[0014] By adopting the above technical solution, the mounting platform can achieve the effect of fixing the device from top to bottom.

[0015] Preferably, the air supply and filtration structure includes a filter assembly, which includes a mounting frame with flanges on both sides. The mounting frame has a funnel inside to facilitate water flow and delivery, and the funnel is connected to a spray head for water delivery and spraying through a cavity block.

[0016] By adopting the above technical solution, the dust suppression effect is achieved through spraying from the spray head.

[0017] Preferably, the filter assembly includes a mounting frame with flanges on both sides, and a flanged cover is symmetrically provided on both sides of the mounting box. The cover has a concave plate with through holes inside, and a magnetic ring for adsorbing and connecting the filter screen is provided inside the concave plate.

[0018] By adopting the above technical solution, the filter screen can be quickly adsorbed and disassembled using a magnetic ring.

[0019] Preferably, the filter assembly includes a cover, which is symmetrically arranged in a mounting box with a hollow internal structure. The mounting box is provided with connecting pipes with a hollow internal structure at the top and bottom.

[0020] By adopting the above technical solution, the conveying air is effectively conveyed through the wrapping cover.

[0021] Preferably, the concave disk, magnetic ring, and filter screen are all connected in a concentric circle shape.

[0022] By adopting the above technical solution, the concave disc achieves a matching installation effect for the filter screen.

[0023] Compared with the prior art, the beneficial effects of this invention are: this underground ventilator rapidly reduces the concentration of carbon monoxide inside the mine.

[0024] (1) The present invention solves the problem of high carbon monoxide concentration in the mine by setting the air supply support component in the air supply and filter structure. When the whole equipment moves into the mine, the fan works and delivers external air into the mine. When the fan delivers air into the mine, the concentration of carbon monoxide in the mine is reduced by the air, thereby avoiding the situation where the carbon monoxide concentration in the mine is too high and employees are easily poisoned by carbon monoxide when they enter the mine.

[0025] (2) By using the filter components in the air supply and filtration structure, the problem of dust carried in the air being transported into the mine along with the blower during operation is solved. When the blower is working, the high-pressure water pump is also working. During the operation of the high-pressure water pump, water is transported into the spray head through the connecting pipe. The water inside the spray head is sprayed into the mounting frame. The sprayed water comes into contact with the transported air, thereby increasing the weight of the dust in the air. At this time, the sprayed water carries the dust into the water tank. The sprayed air is transported into the mine through the filter screen. The above situation is avoided by using the spray head and the filter screen together.

[0026] (3) By setting the swing structure, the air supply and filtration structure always supplies air in the same direction. When the whole device is working, the second hydraulic telescopic cylinder works. During the operation of the second hydraulic telescopic cylinder, the push block is driven to move under force. During the force-driven movement of the push block, the adjusting plate and the driving plate are driven to rotate under force. During the force-driven rotation of the adjusting plate and the driving plate, the air supply and filtration structure and the threaded cylinder are driven to move under force in the same direction. During the force-driven movement of the threaded cylinder, the elastic rope is driven to stretch. When the second hydraulic telescopic cylinder moves in the opposite direction, the elastic rope drives the driving plate and the adjusting plate to elastically recover. By adjusting the plate and the driving plate being driven to rotate and swing under force, the above situation is avoided.

[0027] (4) By setting the base structure, the problem of the overall equipment being inconvenient to move is solved. When the overall equipment needs to be moved inside the mine, the force pushes the force plate to move. During the force plate's movement, the base plate drives the movable wheel to move. During the movable wheel's movement, the overall device is moved inside the mine. Then, during the operation of the first hydraulic telescopic cylinder, the force plate and the ground nail are driven to move in the same direction. When the ground nail is inserted into the ground, the first hydraulic telescopic cylinder stops working to provide force support for the overall equipment. The base structure avoids the above situation. Attached Figure Description

Detailed Implementation

[0038] 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.

[0039] Please see Figure 1-9 This invention provides a technical solution: an underground ventilator for rapidly reducing carbon monoxide concentration inside mines, such as... Figure 1 and Figure 2 As shown, the device includes a base structure 1 that serves as a mobile support. The base structure 1 includes a base plate 101 with a mounting groove at the bottom. The bottom of the base plate 101 is symmetrically provided with movable wheels 102 that allow the entire structure to be moved to different work sites. The movable wheels 102 are connected by first hydraulic telescopic cylinders 105 that are symmetrically provided at the bottom of the base plate 101 to adjust the force plate 103 up and down. The bottom of the force plate 103 is provided with multiple ground nails 104 for support and limiting. There are four movable wheels 102, which are symmetrically installed about the center line of the base plate 101. The movable wheels 102 adopt the universal wheel structure of the prior art to facilitate the steering adjustment of the entire device. At the same time, there are 34 groups of 68 ground nails 104, which provide ground-insertion and limiting support for the entire device through the symmetrically arranged ground nails 104.

[0040] Furthermore, the base structure 1 includes a base plate 101 with a mounting groove at the bottom, and a limiting plate 106 on one side above the base plate 101 to limit the connection of the swing structure 2. The limiting plate 106 is provided with a counterweight to maintain the overall balance and stability of the equipment. The connection shape between the limiting plate 106 and the counterweight is T-shaped. The T-shaped structure of the counterweight and the limiting plate 106 not only facilitates the operator's force adjustment but also makes it convenient for the control box to be installed above the counterweight to control and adjust the components.

[0041] In the above scheme, the operator manually pushes the limiting plate 106 to move under force. During the movement of the limiting plate 106, the base plate 101 drives the movable wheel 102 to move under force. During the movement of the movable wheel 102, the entire device moves in the same direction and moves into the mine. When the entire device moves into the mine, the pushing of the limiting plate 106 stops. Then, the control box controls the first hydraulic telescopic cylinder 105 to work. During the work of the first hydraulic telescopic cylinder 105, the force plate 103 and the ground nail 104 move in the same direction. When the ground nail 104 is inserted into the ground, the first hydraulic telescopic cylinder 105 stops working. At this time, the entire device is supported by force limit, which facilitates the operation of the entire equipment.

[0042] like Figure 3 , Figure 4 and Figure 5As shown, the base structure 1 is provided with a swing structure 2 that controls the left and right movement of the air supply filter structure 3. The swing structure 2 includes a push block 201 with a groove 202 at the bottom. The push block 201 is movably set above the base plate 101 through a matching block 203 and a second hydraulic telescopic cylinder 204. The matching connection between the groove 202 and the matching block 203 plays a role in limiting and adjusting the force on the push block 201 during the force adjustment process.

[0043] Furthermore, the above scheme includes a supporting block 203. The supporting block 203 is equipped with a rotating adjustment disc 206 via a limiting rod 205. One side of the adjustment disc 206 is equipped with a driving plate 207 for force adjustment. One side of the driving plate 207 is equipped with a threaded sleeve 208 with a through hole. The threaded sleeve 208 is equipped with an elastic rope 209 for elastic recovery of the driving plate 207 via a fixing bolt. The adjustment disc 206 is installed with a through hole at the top. The through hole causes the adjustment disc 206 to form an eccentric wheel structure during the force application process. When the adjustment disc 206 is in the form of an eccentric wheel for force adjustment, it drives the driving plate 207 and the air supply filter structure 3 to be subjected to force in the same direction to adjust the swing effect.

[0044] Preferably, there is a set of two threaded sleeves 208, and the two threaded sleeves 208 are conveniently set on one side of the driving plate 207 and the limiting plate 106. The two limiting plates 106 not only facilitate the fixed installation of the two ends of the elastic rope 209, but also allow the elastic rope 209 to provide a force-bearing elastic recovery effect on the adjusting plate 206 and the driving plate 207 in sequence when the elastic rope 209 is under force during installation.

[0045] In the above scheme, the operator controls the second hydraulic telescopic cylinder 204 to work. During the operation of the second hydraulic telescopic cylinder 204, the push block 201 drives the groove 202 and the matching block 203 to move relative to each other under force. During the force movement of the push block 201, it pushes the adjusting plate 206 to rotate under force. During the force rotation of the adjusting plate 206, it drives the driving plate 207 and the threaded sleeve 208 to move in the same direction under force. During the force movement of the threaded sleeve 208, it stretches the elastic rope 209 under force. At the same time, during the force movement of the adjusting plate 206 and the driving plate 207, it drives the air supply filter structure 3 to move in the same direction under force. By reciprocating and changing the force direction of the air supply filter structure 3, the air is quickly distributed inside the mine.

[0046] like Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the air supply and filtration structure 3 includes an air supply support assembly 301 installed on the filter assembly 302. The air supply support assembly 301 includes a water tank 3011 with a high-pressure water pump 3012 installed inside. The water tank 3011 is installed above the regulating plate 206 and the drive plate 207 via a mounting platform 3013. The mounting platform 3013 is equipped with a fan 3014 that supplies air to the mine. The fan 3014 is installed using a flanged fan 3014 as in the existing technology. There are two fans 3014 in one set. By using two symmetrically arranged fans 3014, the air intake is increased and the filtered air is quickly supplied to the mine. The high-pressure water pump 3012 and the fan 3014 are electrically connected to the control box.

[0047] Furthermore, the air supply filtration structure 3 includes a filter assembly 302. The filter assembly 302 includes a mounting frame 3021 with flanges on both sides. The mounting frame 3021 has a funnel 3022 inside for convenient water flow. The funnel 3022 is connected to a spray head 3024 for water delivery spraying through a cavity block 3023. The mounting frame 3021 with flanges facilitates installation with symmetrically arranged fans 3014. The spray head 3024 is an atomizing spray head. Using the atomizing spray head not only expands the spray area and range but also effectively increases the weight of the dust in the air, causing the dust to fall into the funnel 3022 along with the sprayed water.

[0048] Further, the above scheme includes a filter assembly 302 comprising a mounting frame 3021 with flanges on both sides. Symmetrically arranged flanged covers 3025 are provided on both sides of the mounting frame 3021. Inside the covers 3025 is a recessed disc 3026 with through holes. Inside the recessed disc 3026 is a magnetic ring 3027 for adsorption and connection to a filter screen 3028. The concave disc 3026, magnetic ring 3027, and filter screen 3028 are all arranged in a concentric circle. This concentric circle structure not only demonstrates the compatibility between the three components but also their practicality and ease of installation and disassembly. Furthermore, the concentric circle shape of the three components also reflects their axial symmetry.

[0049] Preferably, the cover 3025 is also installed with a flange, so as to effectively connect with the mounting frame 3021. The cover 3025 is designed with a front-wide and back-narrow structure, which also facilitates the matching and connection between the cover 3025 and the mounting frame 3021.

[0050] Furthermore, the above solution includes a filter assembly 302 comprising a cover 3025, which is symmetrically arranged in a hollow mounting box 3029. The mounting box 3029 has hollow connecting pipes 30210 on its top and bottom. There are two connecting pipes 30210, which are respectively connected to the funnel 3022 and the high-pressure water pump 3012, thus facilitating the circulation of water.

[0051] In the above scheme, the operator controls the operation of the blower 3014 and the high-pressure water pump 3012. During the operation of the high-pressure water pump 3012, water from the water tank 3011 is transported to the cavity block 3023 through the connecting pipe 30210. The water entering the cavity block 3023 is sprayed out through the spray head 3024. The water sprayed out by the spray head 3024 performs dust suppression on the air transported by the blower 3014 to the mounting frame 3021. The dust-suppressed water is then transported back to the water tank 3011 through the connecting pipe 30210 for recycling. At the same time, during the operation of the blower 3014, the air that has undergone preliminary dust suppression is transported into the mine through the filter screen 3028, the concave plate 3026 and the magnetic ring 3027 to reduce the carbon monoxide concentration in the mine and ensure the safety of the construction workers.
