[0002] According to actual production needs, the mine needs to construct a reversing chamber with a depth of more than 12 meters in the cut eye to be used for special operation vehicles such as support vehicles to turn around and change direction.

[0003] According to the "Coal Mine Safety Regulations", ventilation measures must be taken for chambers longer than 6 meters to prevent accidents caused by poor ventilation. Extra-long reversing chambers are not conducive to the installation of local ventilators because their special vehicle transport brackets frequently turn around and switch directions. Summary of the Invention

[0004] The purpose of the utility model is to solve the disadvantages of the existing technology that the extra-long reversing chamber is not conducive to the installation of local ventilators due to the frequent turning and switching of special vehicle transport brackets. An underground wind expander is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A downhole wind expander comprises a conical barrel body, a compressed air distributor is fixed in the conical barrel body, a compressed air inlet pipe connected to the compressed air distributor is fixed in the conical barrel body, the compressed air inlet pipe is connected to the compressed air pipeline, a compressed air filter is provided in the compressed air inlet pipe, a two-stage air distributor is also fixed in the conical barrel body, a plurality of fixing rods are fixed at the air outlet of the conical barrel body, a same pressure equalizer is fixed in the plurality of fixing rods, a plurality of connecting rods are fixed in the pressure equalizer, a conical supercharger is fixed at the side end of the plurality of connecting rods, the plurality of conical superchargers are distributed in a ring shape, a conical groove is provided in the plurality of conical superchargers, the compressed air distributor, the two-stage air distributor and the pressure equalizer are connected;

[0007] A fixing ring, which is fixed to the wall of the chamber and has a receiving groove for placing the conical barrel;

[0008] Two sets of connecting components are provided between the conical barrel and the fixing ring, and the two sets of connecting components are used to quickly and stably fix the conical barrel in the fixing ring;

[0009] Two sets of extrusion assemblies, both of which are arranged in the fixing ring and are used to release the connection between the conical barrel and the fixing ring;

[0010] And a driving component used in conjunction with the two groups of extrusion components, wherein the driving component is used to drive the two groups of extrusion components to reset.

[0011] In a possible design, each group of the connecting components includes a first groove opened in the fixing ring, a snap-fit block slides in the first groove, a snap-fit groove that is snap-fitted to the snap-fit block is opened on the surface of the conical barrel body, a spring is fixed to the side end of the snap-fit block, and the spring is fixed in the first groove.

[0012] In a possible design, each group of the extrusion components includes a second groove opened in the fixing ring, a threaded plate slides in the second groove, a screw rod rotates in the second groove, the threaded plate is threadedly connected to the surface of the screw rod, an extrusion rod is fixed to the side end of the threaded plate, an extrusion groove is opened in the clamping block, the extrusion rod moves outward to penetrate into the extrusion groove, and the extrusion rod and the inclined surface of the extrusion groove are in extrusion contact.

[0013] In one possible design, the drive assembly includes an annular groove opened in the fixed ring, and the two screw rods move outward to pass through the annular groove. Driven gears are fixed on the surfaces of the two screw rods, and a driving gear ring that meshes with the two driven gears rotates in the annular groove.

[0014] In one possible design, a rotating ring is fixed on the surface of the driving gear ring, a movable semicircular ring is fixed on the side end of the rotating ring, a fixed semicircular ring for limiting the movable semicircular ring is fixed on the surface of the fixed ring, at least two turning handles are fixed on the surface of the rotating ring, an iron block is fixed inside the movable semicircular ring, and a magnetic block magnetically connected to the iron block is fixed inside the fixed semicircular ring.

[0016] In this application, the compressed air pipeline enters the compressed air distributor through the compressed air inlet pipe, and is sent to the secondary air distributor after passing through the compressed air distributor. The air is evenly sent to the pressure equalizer through the secondary air distributor, and the pressure equalizer makes the air inlet and outlet of the wind expander more balanced;

[0017] After the conical barrel body is inserted into the fixing ring, the conical barrel body is rotated to adjust the position. When the clamping block and the clamping groove match, the elasticity of the spring pushes the clamping block to clamp into the clamping groove, thereby quickly fixing the position of the conical barrel body. When the fixing ring needs to be removed, the swivel is driven by holding the handle to rotate, and the swivel drives the movable semicircular ring to rotate from one end of the fixed semicircular ring to the other end of the fixed semicircular ring. The driving gear ring follows the rotation, and the driving gear ring drives the driven gear to rotate, and the driven gear drives the screw rod to rotate. The rotation of the screw rod drives the threaded plate to move, and the threaded plate drives the extrusion rod to move. The extrusion rod squeezes the inclined surface of the extrusion groove, and the two extrusion grooves are squeezed to move in the direction away from each other, so that the two clamping blocks leave the two clamping grooves respectively, so that the conical barrel body can be easily removed. At the same time, the rotated iron block contacts the other end of the magnetic block, so that the iron block is magnetically fixed by the magnetic block to fix the position of the swivel.

[0018] Beneficial effects:

[0019] In the utility model, the downhole wind expander can achieve the effect of quickly fixing the conical barrel body in the fixing ring through the clamping assembly;

The annular distribution and conical groove design of the conical supercharger effectively improve the uniformity of the air outlet pressure and wind diffusion, thereby improving the ventilation efficiency.
