[0012] Compared with the prior art, the utility model provides a prefabricated inverted T-beam top plate structure for the tailwater pipe of a hydropower station, which has the following beneficial effects:
[0013] 1. The tailwater pipe of the hydropower station is prefabricated with an inverted T-beam top plate structure. The tailwater pipe can be placed in the placement groove first by means of a placement groove, a screw rod, a positioning plate, a turning handle and a threaded seat arranged on the upper surface of the top plate. Then, by rotating the turning handles on both sides, the screw rod is spirally moved and the positioning plate is pushed toward the tailwater pipe, so that the positioning plate contacts the tailwater pipe, thereby positioning and fixing the tailwater pipe in the placement groove, thereby increasing the stability of the tailwater pipe.
[0014] 2. The prefabricated inverted T-beam top plate structure of the tailwater pipe of the hydropower station has reinforcement rods set on both sides of the columns and the top plate. The reinforcement rods are set at a 45° angle, which can play a role in reinforcing support between the columns and the top plate, thereby improving the supporting strength of the tailwater pipe.
[0015] 3. The tailwater pipe of the hydropower station has a prefabricated inverted T-beam top plate structure. Through the leakage holes arranged inside the placement trough, rainwater falling into the inside of the placement trough can be discharged through the leakage holes, thereby avoiding the phenomenon of rainwater accumulation inside the placement trough.
[0016] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can position and clamp the tailwater pipe. At the same time, the T-beam body has high strength, which increases the support stability of the tailwater pipe and improves the power generation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
