Description

Technical Field

[0001] The invention relates to the technical field of mine ventilation detection, in particular to a wind speed monitoring device for an air inlet shaft in a mine ventilation system. Background Art

[0002] The mine ventilation system consists of two parts: the ventilator and the ventilation network. After the airflow enters the mine from the air inlet, it passes through various air-using places underground, and then enters the return air shaft and is discharged from the mine through the return air shaft. The basic tasks of the mine ventilation system are: to supply enough fresh air underground to meet the oxygen needs of personnel; to dilute toxic and harmful gases and dust underground to ensure safe production; to regulate the underground climate and create a good working environment.

[0003] For example, a Chinese patent discloses a wind speed monitoring device for an air intake shaft in a mine ventilation system, with publication number CN112879064B. The wind force inside the air intake shaft tunnel can drive an inner wind direction rod and a wind direction ball to rotate. The inner wind direction rod drives an outer wind direction rod to rotate synchronously through a rotating rod, thereby monitoring the wind speed inside the air intake shaft. When it is necessary to monitor the wind speed at different positions deep inside the air intake shaft, the rotating rod is pressed downward to move downward under the contraction of a limit spring. At the same time, the first connecting rod and the second connecting rod are folded and moved. When the monitoring process is performed within a unit time, the positions of the first connecting rod and the second connecting rod are restricted to remain stationary. The rotation of the outer wind direction rod when the inner wind direction rod is located at different depths inside the air intake shaft can be observed, thereby reducing the error of the wind speed monitoring data inside the air intake shaft.

[0004] This type of monitoring device usually uses a flat mounting base set on the wall of the air inlet shaft, but the wall itself is often circular and has some depressions on it. Therefore, when the traditional mounting base is fixed to the wall by bolts, there will be some gaps. These gaps will cause the bolts of the monitoring device to loosen when encountering external vibrations, and then cause the monitoring device to fall off. Summary of the invention

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For example, see Figure 1-5 , a wind speed monitoring device for an air inlet shaft in a mine ventilation system, comprising a mounting assembly 2, the mounting assembly 2 comprising a mounting base 21 mounted on a wall, a connecting member 22 being provided on the mounting base 21, the connecting member 22 being used for mounting a detector 1;

[0044] A fitting mechanism 3 is provided in the mounting base 21, and the fitting mechanism 3 is used to fill the gap between the mounting base 21 and the air inlet shaft;

[0045] The laminating mechanism 3 comprises a groove 31 formed in the mounting base 21 , and a soft rubber plate 32 is slidably disposed in the groove 31 .

[0046] In this embodiment: the traditional monitoring device sets a flat mounting base on the wall of the air inlet shaft, but the wall itself is often circular and has some depressions on it. Therefore, when the traditional mounting base is fixed to the wall by bolts, there will be several gaps. These gaps will cause the bolts of the monitoring device to loosen when encountering external vibrations, and then cause the monitoring device to fall off.

[0047] In order to fill the gap, the original single mounting base is changed into a mounting assembly 2, which includes a mounting base 21 directly mounted on the well wall, and a connecting piece 22 mounted on the mounting base 21 for setting the detector 1. At the same time, a fitting mechanism 3 is arranged in the mounting base 21. The fitting mechanism 3 includes a groove 31 opened in the mounting base 21, and a soft rubber plate 32 slidably arranged in the groove 31. By pushing the soft rubber plate 32, the soft rubber plate 32 contacts the well wall and deforms to adapt to the shape and depression of the well wall, so that the mounting base 21 can better fit the well wall.

[0048] For example 2, please refer to Figure 4 and 6 , an adjustment mechanism 4 is provided on the mounting base 21, and the adjustment mechanism 4 is used to make the soft rubber plate 32 slide in the groove 31;

[0049] The adjusting mechanism 4 includes a threaded sleeve 42 rotatably disposed in the mounting base 21 . A threaded rod 41 is disposed on the soft rubber plate 32 . The threaded rod 41 is meshedly connected with the threaded sleeve 42 .

[0050] A limiting mechanism 5 is also provided in the mounting base 21, and the limiting mechanism 5 is used to limit the threaded sleeve 42 in the mounting base 21;

[0051] The limiting mechanism 5 includes a limiting groove 51 provided in the mounting base 21 . A limiting block 52 adapted to the limiting groove 51 is provided on the threaded sleeve 42 . The limiting block 52 is disposed in the limiting groove 51 .

[0052] A guide mechanism 6 is also provided in the mounting base 21, and the guide mechanism 6 is used to prevent the soft rubber plate 32 from rotating;

[0053] The guide mechanism 6 includes a guide groove 61 provided in the mounting base 21 . A guide rod 62 adapted to the guide groove 61 is provided on the soft rubber plate 32 . The guide rod 62 is slidably disposed in the guide groove 61 .

[0054] In this embodiment: In order to drive the soft rubber plate 32 to slide in the groove 31, an adjustment mechanism 4 is arranged on the mounting base 21. The adjustment mechanism 4 includes a threaded sleeve 42 rotatably arranged on the detector 1 and a threaded rod 41 arranged on the soft rubber plate 32. The threaded rod 41 is arranged in the threaded sleeve 42 and meshed with it. By rotating the threaded sleeve 42, the threaded rod 41 slides in the threaded sleeve 42, thereby driving the soft rubber plate 32 connected to the threaded rod 41 to slide in the groove 31, so that it is close to the well wall.

[0055] In order to meet the rotation requirement of the threaded sleeve 42 on the mounting base 21, a limiting mechanism 5 is further arranged in the mounting base 21. The limiting mechanism 5 includes a limiting groove 51 opened in the mounting base 21, and a limiting block 52 adapted to the limiting groove 51 is arranged on the threaded sleeve 42. The limiting block 52 is arranged in the limiting groove 51. Through the mutual cooperation between the limiting groove 51 and the limiting block 52, the threaded sleeve 42 can rotate relatively stably in the mounting base 21 and will not separate.

[0056] In order to prevent the soft rubber plate 32 from rotating in the mounting base 21 due to the cooperation of the threaded rod 41 and the threaded sleeve 42, a guide mechanism 6 is further provided in the mounting base 21. The guide mechanism 6 includes a guide groove 61 opened in the mounting base 21, and a guide rod 62 adapted to the guide groove 61 is provided on the soft rubber plate 32. Through the cooperation of the guide groove 61 and the guide rod 62, the soft rubber plate 32 will not rotate in the mounting base 21, so that the adjustment mechanism 4 can normally drive the soft rubber plate 32 to slide.

[0057] For example 3, please refer to Figure 5 and Figure 7 A filling mechanism 7 is also provided in the mounting base 21, and the filling mechanism 7 is used to improve the tightness of the contact between the groove 31 and the air inlet shaft;

[0058] The filling mechanism 7 includes a placement groove 71 provided in the mounting base 21 , a storage bin 72 is slidably disposed in the placement groove 71 , and the storage bin 72 stores the compound.

[0059] A sealing-breaking block 8 is also disposed in the mounting base 21 . The sealing-breaking block 8 is disposed in the placement groove 71 . The sealing-breaking block 8 is used to scratch the surface of the storage bin 72 .

[0060] The placement tank 71 is also provided with an outflow mechanism 9, which is used to divert the compounds in the storage bin 72;

[0061] The outflow mechanism 9 includes a baffle plate 91 disposed in the placement groove 71, and a plurality of diversion holes 92 are formed on the baffle plate 91, and the diversion holes 92 are used to allow the compound to flow out;

[0062] A puncturing block 10 is also rotatably provided on the baffle 91 , and the puncturing block 10 is used to destroy the storage bin 72 .

[0063] A pushing mechanism 11 is also provided in the mounting base 21, and the pushing mechanism 11 is used to quickly push the storage bin 72 to impact the piercing block 10;

[0064] The pushing mechanism 11 includes a pushing spring 111 disposed on the storage bin 72, and the storage bin 72 is connected to the mounting base 21 via the pushing spring 111;

[0065] A limited telescopic rod 112 is also provided on the storage bin 72 . The storage bin 72 is also connected to the mounting base 21 via the limited telescopic rod 112 , and the push spring 111 is sleeved on the outside of the limited telescopic rod 112 .

[0066] In this embodiment: Although the mounting base 21 can be fitted to the well wall by simply relying on the soft rubber plate 32, the depression on the well wall will still cause gaps in the direct connection between the mounting base 21 and the well wall, and there is a possibility of loosening. Therefore, in order to fill these gaps, a filling mechanism 7 is also provided in the mounting base 21. The filling mechanism 7 includes a placement groove 71 opened in the mounting base 21, and a storage bin 72 is provided in the placement groove 71. A certain amount of compound is stored in the storage bin 72. By destroying the storage bin 72, the compound inside it flows out, thereby filling the depression between the soft rubber plate 32 and the well wall, thereby improving the connection effect between the mounting base 21 and the well wall.

[0067] In order to allow the compounds in the storage bin 72 to flow out more evenly, an outflow mechanism 9 is further provided in the placement groove 71. The outflow mechanism 9 includes a baffle plate 91 provided in the placement groove 71. A plurality of diversion holes 92 are provided on the baffle plate 91. The diversion holes 92 are used to divert the compounds to prevent them from flowing out from one angle.

[0068] At the same time, in order to allow scratches to be generated on the surface of the storage bin 72 when it slides in the placement groove 71, so that it can be easily destroyed, a breaking block 8 is also provided in the placement groove 71. The breaking block 8 abuts against the outer wall of the storage bin 72, and then when the storage bin 72 slides, it can rub the outer wall of the storage bin 72, thereby making the storage bin 72 more fragile, so as to facilitate its final destruction.

[0069] At the same time, a puncture block 10 is provided on the baffle 91, and the puncture block 10 is used to destroy the storage bin 72 to allow the compound inside to flow out.

[0070] In order to accelerate the storage bin 72 to hit the puncture block 10, thereby ensuring that the storage bin 72 is destroyed by the puncture block 10, a pushing mechanism 11 is also provided on the storage bin 72. The pushing mechanism 11 includes a pushing spring 111 installed on the storage bin 72. The storage bin 72 is elastically connected to the mounting base 21 through the pushing spring 111. When the storage bin 72 slides toward the direction close to the detector 1, the pushing spring 111 will be squeezed by the storage bin 72, thereby generating and accumulating elastic potential energy. When the storage bin 72 is detached from the fixation, the pushing spring 111 will release the accumulated elastic potential energy, thereby pushing the storage bin 72 to quickly approach the puncture block 10, thereby ensuring that the storage bin 72 can contact the puncture block 10 with a larger initial velocity, thereby being destroyed by the puncture block 10.

[0071] In order to make the storage bin 72 more stable when sliding and prevent the push spring 111 from bending when elastic deformation occurs, a limiting telescopic rod 112 is provided on the storage bin 72. The storage bin 72 is also connected to the mounting base 21 through the limiting telescopic rod 112, and the push spring 111 is sleeved on the limiting telescopic rod 112. The limiting telescopic rod 112 is used to make the sliding of the storage bin 72 more stable and to limit the push spring 111 to avoid bending.

[0072] Due to the different shapes of different well walls, in order to facilitate the compound to strengthen the connection between the soft rubber board 32 and the well wall, a number of secondary flow holes 14 are also opened in the mounting base 21. One side of each secondary flow hole 14 is connected to the placement groove 71, and the other side of each secondary flow hole 14 is connected to the groove 31. Then, the compound in the placement groove 71 can be guided into the groove 31 through the secondary flow holes 14, thereby preventing the compound from being unable to fully fill the depression due to the soft rubber board 32 not fully protruding out of the groove 31. At the same time, since there are multiple secondary flow holes 14, the specific number of opening and closing holes can be adjusted according to actual conditions. Unnecessary secondary flow holes 14 will be blocked by the soft rubber board 32, which also avoids compound waste to a certain extent.

[0073] Example 4, please refer to Figure 4 , Figure 5 as well as Figure 8 , a moving mechanism 12 is also provided in the mounting base 21, and the storage bin 72 is also connected to the soft rubber plate 32 through the moving mechanism 12;

[0074] The moving mechanism 12 includes a cavity 121 opened in the mounting base 21 , a gear 122 is rotatably arranged in the cavity 121 , a first rack 123 meshing with the gear 122 is arranged on the fitting mechanism 3 , and a second rack 124 meshing with the gear 122 is arranged on the storage bin 72 .

[0075] A disconnection mechanism 13 is disposed in the mounting base 21, and the disconnection mechanism 13 is used to disconnect the connection between the storage bin 72 and the second rack 124;

[0076] The disconnecting mechanism 13 includes an assembly block 131 disposed in the placement groove 71 , and an interference block 132 is disposed on the storage bin 72 . The storage bin 72 is connected to the second rack 124 via the interference block 132 .

[0077] In this embodiment: In order to allow the storage bin 72 to approach the detector 1 when the soft rubber plate 32 approaches the well wall, so that it can be triggered by the pushing mechanism 11 and thus increase the impact speed, a moving mechanism 12 is further provided in the mounting base 21, and the moving mechanism 12 includes a cavity 121 opened in the mounting base 21, and the cavity 121 is respectively connected to the groove 31 and the placement groove 71, and a gear 122 is rotatably provided in the cavity 121, and a first rack 123 is provided on the soft rubber plate 32, and a second rack 124 is provided on the storage bin 72, the first rack 123 and the second rack 124 are respectively meshed with the gear 122, and are symmetrically provided on both sides of the gear 122, when the soft rubber plate 32 slides in the direction approaching the well wall, the first rack 123 will drive the gear 122 to rotate, and then drive the second rack 124 to slide in the opposite direction, thereby driving the storage bin 72 to slide in the direction approaching the detector 1.

[0078] In order to cut off the connection between the storage bin 72 and the second rack 124, so that the storage bin 72 can quickly approach the puncture block 10 under the action of the pushing mechanism 11, a disconnecting mechanism 13 is also provided in the mounting base 21. The disconnecting mechanism 13 includes an assembly block 131 arranged in the placement groove 71, and a resistance block 132 is provided on the storage bin 72. The storage bin 72 is connected to the second rack 124 through the resistance block 132. When the storage bin 72 approaches the detector 1, the assembly block 131 will resist the contact block 132, thereby breaking it. At this time, the storage bin 72 will lose the connection with the second rack 124 through the resistance block 132, and then quickly approach the puncture block 10 under the action of the pushing mechanism 11 to be destroyed by it.

[0079] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
