Anti-blocking device for tunnel drainage

Technical Field

The utility model relates to the field of anti-blocking devices, in particular to an anti-blocking device for tunnel drainage.

Background Art

Tunnel waterproofing and drainage refers to the waterproofing and drainage measures taken to ensure that tunnel construction will not be damaged by water leakage, endanger driving safety, corrode equipment in the tunnel, and reduce the service life of the structure. It is a comprehensive work involving factors such as topography, climate, engineering strata and hydrogeology, structural schemes, construction methods and material properties; the basic requirement should be prevention first. After the construction of the tunnel, the original water system balance of the mountain is destroyed, and the tunnel becomes a channel for the accumulation of groundwater near the mountain through which it passes.

Please refer to FIG. 1 to FIG. 4 , an anti-blocking device for tunnel drainage includes a drainage channel 1 and an automatic cleaning device 2; the automatic cleaning device 2 is equipped with a torque motor 21, a transmission bevel gear 22 is fixedly installed at the output end of the torque motor 21, a fixed bevel gear 23 is transmission-connected to the other side of the transmission bevel gear 22, a transmission shaft 24 is penetrated and movably installed on one side of the fixed bevel gear 23, second gears 25 are penetrated and fixedly installed on both sides of the transmission shaft 24, and transmission chains 26 are transmission-connected to the four sides of the two second gears 25;

During operation, the torque motor 21 transmits power, and the transmission chain 26 is driven by the second gear 25 fixed on the transmission shaft 24 under the cooperation of the transmission bevel gear 22 and the fixed bevel gear 23, so as to realize the rotation of the transmission chain 26.

Furthermore, the drainage channel 1 includes a housing 11, and two support bearings 12 are fixedly installed on the inner wall of the housing 11, and a fixing rod 14 is penetrated and movably installed on one side of the two support bearings 12;

During operation, the fixing rod 14 is supported and limited by the support bearing 12 , so that the fixing rod 14 is fixed inside the housing 11 , and is used as a support for the bottom of the transmission chain 26 , so that the transmission chain 26 is always in a taut state.

Furthermore, first gears 13 are passed through and fixedly installed at both ends of the fixing rod 14, and transmission chains 26 are respectively connected to the periphery of the two first gears 13;

During operation, the installation fixing rod 14 can well carry the transmission chain 26 , which is conducive to the stable operation of the transmission chain 26 and ensures that the transmission chain 26 follows a consistent moving trajectory.

Furthermore, a plurality of movable rods 27 are fixedly installed around the two transmission chains 26, and a plurality of hook teeth 28 are fixedly installed on one side of the plurality of movable rods 27;

During operation, the transmission chain 26 rotates to make the movable rod 27 fixed around the transmission chain 26 rotate synchronously, so that the hook teeth 28 fixed on one side of the movable rod 27 contact the stones or garbage on the blocking net 29, and the stones or garbage are moved accordingly by the movement of the hook teeth 28.

Furthermore, a groove is provided on one side of the top of the housing 11 and a blocking net 29 is fixedly installed thereon, a guide plate 201 is fixedly installed on the top of the blocking net 29, and a collecting bucket 16 is placed on the top of the housing 11;

During operation, when the stones or garbage on the retaining net 29 move to the top of the guide plate 201 along with the hook teeth 28, the stones or garbage will fall into the collecting bucket 16 under their own weight for collection. When the collecting bucket 16 has collected to a certain extent, the personnel can move the collecting bucket 16 to clean up the stones or garbage inside.

Furthermore, two fixed bearings 15 are fixedly installed on the top of the housing 11, a transmission shaft 24 is movably installed between the two fixed bearings 15, and a torque motor 21 is fixedly installed on one side of the housing 11;

Working principle: The transmission bevel gear 22 at the output end is rotated by driving the torque motor 21. The transmission bevel gear 22 transmits the fixed bevel gear 23 during operation, so that the fixed bevel gear 23 drives the transmission shaft 24 to rotate. When the transmission shaft 24 rotates, it transmits the transmission chain 26 through the second gear 25. In this way, the movable rod 27 is relatively displaced by the movement of the transmission chain 26. The hook teeth 28 installed on the movable rod 27 scrape the debris on the baffle 29 as it moves, so that the garbage or stones blocked on the baffle 29 move with the hook teeth 28. When the garbage or stones move to the top of the guide plate 201, the garbage or stones are thrown into the collecting bucket 16 for collection.
