Perforated aluminum-plastic composite pressure pipe

Abstract

The invention relates to the technical field of pressure pipes, and discloses a perforated aluminum-plastic composite pressure pipe. The perforated aluminum-plastic composite pressure pipe comprises aframe body. The bottom of the frame body is fixedly connected with a support body. The bottom of the support body is fixedly connected to the top of a mounting plate. One side of the support body ismovably connected with a rotary rod. One end of the rotary rod penetrates through the support body and is fixedly connected with the inner wall of a first bevel gear. The first bevel gear is engaged with a second bevel gear. The inner wall of the second bevel gear is fixedly connected with a rotating rod. One end of the rotating rod sequentially penetrates through the support body, the frame bodyand a gear and is fixedly connected with the inner wall of a first bearing. The surface of the first bearing is fixedly connected to the inner wall of the top of the frame body. The gear is engaged with a rack moving plate. The top of the rack moving plate is fixedly connected with a support rod. According to the perforated aluminum-plastic composite pressure pipe, through cooperation of the rotary rod and the rotating rod, a worker can adjust the length of a composite pressure pipe bracket conveniently, and the requirement for support of pressure pipes of different sizes of the worker can bemet.

Description

technical field [0001] The invention relates to the technical field of pressure pipes, in particular to a perforated aluminum-plastic composite pressure pipe. Background technique [0002] The water flow guiding technology of the penstock first originated from the fact that when the water flow drives the waterwheel, the rotating wheel generates energy and uses this energy to grind the grain. The earliest penstock is not in the form of a steel pipe, but in the form of a long channel. Therefore, the term penstock was first called pressure pipe. Historically, the channel form was the most commonly used. At that time, the pressure pipe would be connected with the existing waterway, and when the water gate at the water source was fully opened, Water can flow freely into the penstock, but when the sluice gate is closed, the flow of water is restricted and cannot flow into the penstock. In addition, additional fences or filters are usually installed at the inlet of the penstock to ...
