Problems solved by technology

Although some of the monitoring methods proposed at present are relatively mature in technology, they have not been popularized and applied in a large area. One of the main reasons is that the power supply problem of the monitoring system has not been well resolved.

Abstract

The invention relates to a step by step indirect excitation type current generator, and belongs to the power generating field; an end cap is arranged on the housing cylinder wall end portion, and provided with a boss and inner ear plates; the boss is provided with a limit plate; two sides of the boss are provided with energy transducers; the inner ear plate is provided with a reed; two ends of a square guide pillar are respectively fixed on the two inner ear plates; the square guide pillar is sleeved by inner springs and an inertia block; the inner springs are arranged on top and bottom sides of the inertia block; the left and right sides of the inertia block are respectively provided with a push block and an excited magnet; the push block is arranged between two energy transducers; the energy transducer free end makes contact with the push block, yes not action force is formed; a coil is embedded on the inner side of the housing bottom wall, and an upper ear plate and a lower ear plate are arranged outside the housing bottom wall; the upper and lower ear plates are mutually connected through two round guide pillars; two ends of a bluff body are respectively sleeved on the two round guide pillars; the bluff body is a hollow structure; the round guide pillar is sleeved by two external springs; two ends of the external spring respectively press on the bluff body and the upper ear plate or the lower ear plate; the wing plates of the bluff body are provided with exciting magnets; the isomerism magnetic poles of the exciting magnet and the excited magnet are arranged in opposite.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a step-by-step indirect excitation type water flow generator for powering a river monitoring system. Background technique [0002] There are thousands of rivers all over the territory of our country. In recent years, due to insufficient treatment of industrial wastewater, soil erosion, and improper use of pesticides and fertilizers, most rivers have been polluted to a certain extent. Nearly 1 / 4 of the rivers or river sections cannot meet basic irrigation due to pollution. need. In addition, because the current flood control facilities for small and medium-sized rivers in many areas are not perfect, or even do not have any flood control facilities, when the flood season comes, it may cause dangers such as embankment failure or flooding, directly threatening the lives and property safety of people along the coast. Therefore, river monitoring has been highly v...
