Description

Technical Field

[0001] The present invention relates to the technical field related to ventilators, and in particular to an adjustable mining ventilator. Background Art

[0002] Mine ventilation refers to the process of introducing fresh air into the mine to increase the oxygen concentration, so as to dilute and remove toxic and harmful gases and dust in the mine. The basic tasks of mine ventilation are: to supply enough fresh air underground to meet the oxygen needs of personnel; to dilute harmful gases and dust underground to ensure safe production; to regulate the underground climate and create a good working environment. Mine ventilation is a mandatory requirement in the laws and regulations on coal mine safety production, and is an important measure to ensure mine safety production and the safety of miners' lives.

[0003] In the existing mine ventilation process, such as the Chinese patent with publication number CN221703759U, a ventilation device for preventing coal mine gas from exceeding the limit is disclosed, including: a ventilation mechanism, including a mine fan assembly, a motor assembly for driving the mine fan assembly to rotate; a rotating mechanism, including a rotating table assembly for supporting the rotation of the mine fan assembly, a telescopic assembly installed on the rotating table assembly, and the motor assembly is fixedly installed on the rotating table assembly.

[0004] In the above-mentioned prior art, the angle of the ventilator assembly is adjusted in multiple directions mainly by cooperating with the rotating table assembly and the motor assembly, so as to achieve better ventilation effect. However, the above-mentioned prior art does not take into account the change of humidity inside the mine. The depth of the mine is usually in contact with groundwater, or the mine wall and ore contain moisture, so the relative humidity in the mine is often high. Especially in places close to the groundwater layer or the mine water, the humidity may be very high. Excessive humidity can easily cause miners to suffer from diseases such as arthritis and pneumonia, affecting their health. It can also cause corrosion to electronic equipment. In severe cases, it may even affect the stability of the mine, especially in weak rock formations. The penetration of water may cause the rock formation to soften, increasing the risk of collapse and landslide. On the other hand, in some arid or semi-arid areas, the air outside the mine is relatively dry. As the depth of the mine increases, although the humidity usually increases, it may also be due to geological conditions. The air humidity in deep mines is low, and dry air can still cause some health problems for miners: such as dry skin, sore throat, respiratory tract, etc. In addition, dry air may increase the generation of static electricity, and static electricity discharge may cause explosion or fire, which is very dangerous, especially in an environment with flammable gas or dust.

[0005] Based on this, there is still room for improvement in the above-mentioned prior art. Summary of the invention

[0033] The following is combined with Figure 1-Figure 12 This application is described in further detail.

[0034] The embodiment of the present application discloses an adjustable mining ventilator, which flexibly adjusts the angle of the fan blades 4 and combines air drying and humidification operations according to the angle of the fan blades 4 to ventilate the mine while optimizing the air humidity to create a good working environment for miners.

[0035] Reference Figure 1-Figure 4 As shown, an adjustable mining ventilator includes a wind tube 1, a motor 2, a turbine hub 3, blades 4, an adjustment module 5, a reinforcement module 6, a linkage module 7, a drying module 8, and a humidification module 9. A base is installed at the bottom of the wind tube 1, the motor 2 is installed inside the wind tube 1 through a motor seat, the turbine hub 3 is installed on the output end of the motor 2, and the outer periphery of the turbine hub 3 is evenly rotated with blades 4. The turbine hub 3 and the blades 4 are matched through the adjustment module 5. The adjustment module 5 controls the blades 4 to adjust the angle so as to change the flow rate and wind pressure. The reinforcement module 6 is arranged on the turbine hub 3. The reinforcement module 6 strengthens and stabilizes the blades 4 when necessary. The linkage module 7 is arranged on the turbine hub 3. The drying module 8 is arranged on the inner rear side of the wind tube 1. The drying module 8 dries the air. The humidification module 9 is arranged inside the wind tube 1. The humidification module 9 humidifies the air.

[0036] In the actual ventilation process, the motor 2 starts to drive the turbine hub 3 to rotate, and the fan blades 4 rotate with the turbine hub 3 to generate suction to suck fresh air from the outside into the interior of the mine. When the humidity in the mine is too high (the mine is usually equipped with a humidity sensor), the adjustment module 5 is started, and the adjustment module 5 increases the angle of the fan blades 4. At the same time, the drying module 8 is started, and the strengthening module 6 is started. The strengthening module 6 strengthens and stabilizes the fan blades 4, and the drying module 8 dries the air. The fan blades 4 begin to transport dry air to the interior of the mine. The angle increases, the wind pressure increases, and the dry air is transported to the depth of the mine as much as possible. When the humidity in the mine is too low, the regulating module 5 adjusts the angle of the fan blade 4 to reduce it. At the same time, the humidification module 9 is started, and the humidification module 9 humidifies the air. The fan blades 4 pass the humidified air into the mine, thereby maintaining the humidity of the air in the mine within a suitable range. The present application selectively enhances the wind pressure or air volume according to the humidity conditions in the mine through the adjustment of the fan blades 4, and cooperates with the air drying or humidification operation to quickly and comprehensively adjust the humidity of the air inside the mine.

[0037] Reference Figure 4 As shown, in order to adjust the angle of the fan blade 4, the present application is provided with an adjustment module 5, which includes an adjustment gear 51, a disc gear 52, and an auxiliary plate 53. The adjustment gear 51 is installed on the inner end of the fan blade 4 through an auxiliary part, and the disc gear 52 is rotatably set on the turbine hub 3 through an electric turntable. The disc gear 52 is meshed with the adjustment gear 51, and the auxiliary plate 53 is installed on the back side of the disc gear 52. The auxiliary plate 53 and the turbine hub 3 are rotationally matched.

[0038] Reference Figure 4 As shown, in the initial state, the angle of the fan blade 4 (the angle between the fan blade 4 and the rotating plane) is in a balanced position. When the angle of the fan blade 4 increases, the changes in the wind volume and wind pressure are as follows: Decrease in wind volume: When the angle of the fan blade 4 increases, the force of the blade on the air is more inclined to compress the air rather than to push the air flow, which will cause the wind volume (i.e., the amount of air passing through per unit time) to decrease. Increase in wind pressure: A larger angle of the fan blade 4 will increase the generated wind pressure, which is beneficial for applications that require higher pressure (such as when the ventilation duct is long or the resistance is large). When the angle of the fan blade 4 decreases, the changes in wind volume and wind pressure are as follows: Increase in wind volume: When the angle of the fan blade 4 decreases, the force of the blade on the air is more inclined to push the air flow, which will cause an increase in wind volume, i.e., an increase in the amount of air passing through per unit time. Decrease in wind pressure: A smaller angle of the fan blade will reduce the wind pressure generated by the fan, which is not conducive to applications that require higher pressure.

[0039] During the actual angle adjustment process, when the electric turntable drives the adjusting gear 51 to rotate clockwise, the adjusting gear 51 rotates under the meshing action, and the angle rotation of the fan blade 4 increases. When the electric turntable drives the adjusting gear 51 to rotate counterclockwise, the adjusting gear 51 rotates under the meshing action, and the angle rotation of the fan blade 4 decreases.

[0040] Reference Figure 4 , Figure 5 , Figure 7 As shown, when the angle of rotation of the fan blade 4 increases, the fan blade 4 is subjected to greater force when rotating. In order to strengthen the fan blade 4, the present application is provided with a reinforcement module 6, which includes a reinforcement ring 61, a stabilizing pin 62, an extrusion piece 63, and a push-out piece 64. The reinforcement ring 61 is rotatably arranged on the inner wall of the wind tube 1, and the reinforcement ring 61 and the outer end of the fan blade 4 are rotatably matched. The reinforcement ring 61 can increase the overall structural strength of the fan blade and reduce the bending or vibration that may occur when the fan blade rotates at high speed. By connecting all the fan blades 4, the reinforcement ring 61 helps to balance the vibration of the fan blade 4 and reduce the imbalance problem caused by the uneven weight or installation deviation of a single fan blade 4, thereby reducing noise and improving the operating stability of the equipment. The stabilizing pin 62 is radially slidably arranged in a sliding groove opened inside the fan blade 4. A spring 1 is connected between the stabilizing pin 62 and the sliding groove, and the spring acts together to reset. The inner end of the stabilizing pin 62 is installed with an extrusion piece 63, and the push-out piece 64 is installed on the auxiliary plate 53. The push-out piece 64 and the extrusion piece 63 are extrusion-matched.

[0041] Reference Figure 3 , Figure 5 , Figure 6 As shown, an arc-shaped sliding groove 31 is provided on the outer periphery of the turbine hub 3, and the inner end of the stabilizing pin 62 passes through the sliding groove 31. The sliding groove 31 plays a role of avoidance. When the fan blade 4 rotates, the stabilizing pin 62 moves following the fan blade 4. The sliding groove 31 provides the necessary conditions for the displacement of the stabilizing pin 62 to avoid interference and jamming. A fixing groove 611 corresponding to the outer end position of the stabilizing pin 62 is provided on the inner wall of the reinforcement ring 61. The fixing groove 611 is arc-shaped, and the depth of the fixing groove 611 gradually increases from the outside to the inside. When the fan blade 4 rotates clockwise, the fixing groove 611 of the stabilizing pin 62 plays a role.

[0042] During the actual reinforcement process, when the angle of rotation of the fan blade 4 increases, the stabilizing pin 62 rotates with the fan blade 4, the extrusion member 63 and the ejection member 64 are in contact and squeezed, the extrusion member 63 is squeezed and moved outward, and the stabilizing pin 62 moves outward and enters the fixing groove 611, and the stabilizing pin 62 is temporarily abutted against the fixing groove 611, thereby supporting the fan blade 4 and enabling the fan blade 4 to withstand greater wind pressure.

[0043] Reference Figure 3 , Figure 7 As shown, the present application is provided with a linkage module 7 as a linkage transition, and the linkage module 7 includes a linkage extrusion block 1 71, a linkage extrusion block 2 72, a trigger block 1 73, and a trigger block 2 74. The linkage extrusion block 1 71 is radially slidably arranged on the outer periphery of the turbine hub 3, and a spring 2 is connected between the linkage extrusion block 1 71 and the turbine hub 3, and the spring 2 plays a reset role. The linkage extrusion block 2 72 is radially slidably arranged on the outer periphery of the turbine hub 3, and a spring 3 is connected between the linkage extrusion block 2 72 and the turbine hub 3, and the spring 3 plays a reset role. The linkage extrusion block 1 71 and the linkage extrusion block 2 72 are arranged front to back, and the trigger block 1 73 is installed on the auxiliary plate 53, and the trigger block 1 73 and the linkage extrusion block 1 71 are extrusion-fitted. The trigger block 2 74 is installed on the auxiliary plate 53, and the trigger block 2 74 and the linkage extrusion block 2 72 are extrusion-fitted.

[0044] During actual operation, the auxiliary plate 53 rotates with the disc gear 52. If the auxiliary plate 53 rotates clockwise, the linkage extrusion block 1 71 is in contact and squeezed with the trigger block 1 73, and the linkage extrusion block 1 71 is squeezed to extend outward. The extended linkage extrusion block 1 71 triggers the drying module 8. If the auxiliary plate 53 rotates counterclockwise, the linkage extrusion block 2 72 is in contact and squeezed with the trigger block 2 74, and the linkage extrusion block 2 72 is squeezed to extend outward. The extended linkage extrusion block 2 72 triggers the humidification module 9.

[0045] Reference Figure 2 , Figure 8 As shown, in order to purify the moisture in the air to obtain dry air, the present application is provided with a drying module 8, which includes a heating net 81, a heating switch 82, a pressing piece 83, and a power supply. The heating net 81 is installed on the inner wall of the wind tube 1. The heating net 81 is a prior art. When the heating net 81 is started, the air is heated by passing through the heating net 81, thereby drying the air. The heating switch 82 is installed inside the wind tube 1 through an auxiliary bracket, and the pressing piece 83 is slidably arranged on the auxiliary bracket left and right. A spring four is connected between the pressing piece 83 and the auxiliary bracket, and the spring four plays a resetting role.

The power supply is installed on the outside of the wind tube 1 through an insulating shell, and the power supply, the heating switch 82, and the heating net 81 are electrically connected.

[0046] In the actual process of drying the air, the outwardly extended linkage extrusion block 71 squeezes the pressing piece 83, and the pressing piece 83 is displaced after being squeezed, thereby pressing the heating switch 82, and a connecting circuit is formed among the power supply, the heating switch 82, and the heating network 81. The heating network 81 works to emit heat, and the air attracted by the fan blades 4 is heated after passing through the heating network 81, and the moisture in the air is evaporated. The dry air is continuously transported to the depth of the mine by the fan blades 4, thereby adjusting the overly humid air environment in the mine.

[0048] In the actual process of humidifying the air, the outwardly extended linkage extrusion block 2 72 squeezes the pressing piece 2 93, and the squeezed pressing piece 2 93 is displaced to press the starting switch 92. A connecting circuit is formed between the electric drive component 95, the power supply, and the starting switch 92. The water spray component 91 starts to spray water mist. The air attracted by the fan blades 4 contacts the water mist and blows it to evaporate. The evaporated water mist follows the air into the mine to increase the humidity inside the mine. The diffusion mechanism 94 assists the evaporation of the water mist.

[0049] Reference Fig. 9 , Fig.10 As shown, the water spray assembly 91 includes a nozzle 911, a water pipe 912, a valve 913, and a belt assembly 914. The nozzle 911 is evenly installed on the top inner wall of the wind cylinder 1.

The water pipe 912 is installed on the outer wall of the wind cylinder 1. The water pipe 912 is connected to the nozzle 911. A water storage space is provided in the base, and a water pump is installed in the water storage space. The water pipe 912 is connected to the water pump. The valve 913 is installed on the water pipe 912. The valve 913 in the prior art needs to be turned one circle to open. The valve 913 and the mounting column 97 are matched through the belt assembly 914.

[0050] In the actual process of water spraying, the electric drive assembly 95 is started to drive the belt assembly 914 to rotate and open the valve 913. After that, the water flows through the water pump and the water pipeline 912 and is sprayed out from the nozzle 911 in atomized form.

[0051] Reference Figure 9-12 As shown, in order to better evaporate water, the present application is provided with a diffusion mechanism 94, which includes a guide rail bracket 941, a support plate 1 942, a support plate 2 943, a support plate 3 944, an evaporation belt 945, a transition roller 946, and a belt 947. The guide rail bracket 941 is installed on the rear inner wall of the wind tube 1, and the cross-section of the guide rail bracket 941 is L-shaped. The support plate 1 942 is installed in the middle of the guide rail bracket 941. The support plate 1 942 is a grid plate structure. The support plate 2 943 is slidably arranged on the guide rail bracket 941, and the support plate 3 944 is slidably arranged on the guide rail bracket 941. The structures of the support plates 1 942, 2 943, and 3 944 are all the same. , support plate 2 943 and support plate 3 944 are respectively located on both sides of support plate 1 942, and support plate 1 942, support plate 2 943, and support plate 3 944 are respectively connected by evaporation belt 945. Evaporation belt 945 is a carbon fiber composite material of the prior art. By adjusting the matrix composition and interface treatment, the carbon fiber composite material can achieve good water absorption and high temperature resistance. Transition roller 946 is installed on mounting column 97. The radius of transition roller 946 is large, so as to ensure that when transition roller 946 rotates one circle, belt 947 moves a sufficiently long distance. A rotating pin is rotatably provided on guide rail bracket 941, and transition roller 946 and the rotating pin are matched through belt 947.

[0052] Reference Fig.11 As shown, the support plate 2 943 is connected to the lower part of the belt 947, and the support plate 3 944 is connected to the upper part of the belt 947. When the belt 947 rotates, the support plate 2 943 and the support plate 3 944 move away from each other in opposite directions.

[0053] During actual auxiliary evaporation, the electric drive component 95 is started to rotate the mounting column 97, and the transition roller 946 rotates following the mounting column 97. The belt 947 rotates driven by the transition roller 946, thereby driving the support plate 2 943 and the support plate 3 944 to expand and open. The evaporation belt 945 is flattened, and the atomized water droplets fall on the evaporation belt 945. The evaporation belt 945 increases the surface area of ​​the water, so that more water molecules have the opportunity to transform from liquid to gas. At the same time, the sprayed water mist is easy to remain on the inner wall of the equipment and accumulate. The existence of the evaporation belt 945 absorbs excess water, reduces the residual water on the inner wall of the equipment, and reduces the occurrence of corrosion.

[0054] The implementation principle of this embodiment is:

[0055] Step 1: The motor 2 is started to drive the turbine hub 3 to rotate, and the fan blades 4 rotate along with the turbine hub 3 to generate suction to draw fresh air from the outside into the mine;

[0056] Step 2: When the humidity in the mine is abnormal, there are two situations:

[0057] A: When the humidity in the mine is too high: the regulating module 5 increases the angle of the fan blade 4, and at the same time, the drying module 8 is started, the strengthening module 6 is started, the strengthening module 6 strengthens and stabilizes the fan blade 4, the drying module 8 dries the air, and the fan blade 4 starts to transport dry air into the mine;

[0058] B: When the humidity in the mine is too low: the electric drive component 95 is started, the water spray component 91 sprays atomized water droplets, the diffusion mechanism 94 increases the evaporation area to assist evaporation, thereby humidifying the air, and the fan blades 4 pass the moist air into the mine.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
