Abstract

The invention provides a water flow direction sensor and belongs to the sensor technical field. The water flow direction sensor comprises a universal board for inducing a water flow direction; one side edge of the universal board is fixedly connected with a steering shaft; the upper part of the steering shaft is arranged on a rack base; the steering shaft is rotatably connected with the rack base;a supporting frame is arranged on the rack base; the upper end of the steering shaft is sequentially sleeved with a first cam and a second cam; the left end of the first cam and the right end of thesecond cam are connected with the supporting frame through horizontal telescopic components; and the horizontal telescopic components are provided with strain gratings connected with a receiver. The impact force of water flow is utilized to make the universal board rotate to a direction consistent with the direction of the water flow from an initial position; the rotation of the universal board drives the steering shaft, the first cam and the second cam to rotate, which results in the strain difference of the horizontal telescopic components and the strain gratings thereof at two sides; the strain gratings are utilized to measure the strain difference of the horizontal telescopic components, so that the direction of the water flow can be measured indirectly; and 360-degree monitoring of the direction of the water flow can be realized.

Description

technical field [0001] The invention belongs to the technical field of sensors, and more specifically relates to a water flow direction sensor. Background technique [0002] During the long-term use of offshore structures, they are constantly affected by factors such as the erosion of ocean currents, the impact of ocean waves, and the growth of marine organisms, resulting in dynamic softening of the foundation of offshore structures and erosion and aging of materials, resulting in attenuation of offshore structural components and overall resistance. , affecting the safety and durability of the structure. Therefore, long-term monitoring of ocean currents is of great importance to grasp the performance evolution of offshore structures, evaluate the working status of structures, carry out targeted and reasonable maintenance, avoid various safety accidents, ensure the safety of offshore structures and increase their service life. Significance, and the direction of water flow is...
