Abstract

The invention discloses a jet flow force measuring method of a netting cleaning disc. By means of the first step, the second step, the third step and the fifth step, impact force measurement data of cavitation jet flow generated by the netting cleaning disc under different jet distances and jet radiuses can be measured, measurement is conducted at the same time through at least three pressure sensors under the same jet radius, and the reliability of the impact force measurement data of the cavitation jet flow is improved. Moreover, a sensor moving mechanism composed of a sliding block, a synchronous pulley, a guide roller and a synchronous belt is adopted, so that the positions, namely the injection radiuses, of the four pressure sensors can be accurately, quantitatively and synchronouslyadjusted, the measurement precision of impact force measurement data can be improved, and the reliability is high.

Description

technical field [0001] The invention relates to a performance test method of net clothes cleaning equipment in deep water net cages, in particular to a jet force measurement method for net clothes cleaning discs. Background technique [0002] When the cage culture system is soaked in water for a long time, a large number of algae, shellfish and other organisms in the ocean will adhere to the net clothing. The increase of attachments hinders the smooth flow and exchange of water bodies inside and outside the cage, causing problems such as the decrease of dissolved oxygen in the cage, mechanical damage to the fish body, and difficulty in changing the net clothing. The place where pathogens grow and reproduce, induces the outbreak of fish diseases, and even causes large-scale death of fish schools. The mechanization and automation of net cleaning is one of the most effective means to solve the management of the breeding process and reduce the risk of breeding. [0003] Such a...
