The friction nano generator array 2 comprises a plurality of bionic friction nano generators 201 arranged in front and back, the upper ends of the bionic friction nano generators 201 are fixedly connected with the top of the upper shell 101, the bottoms of the bionic friction nano generators are free to droop, and the positive electrodes and the negative electrodes of the bionic friction nano generators 201 are connected in parallel and then led out. The anti-scale electric field electrode comprises an anti-scale electric field negative electrode 301 and an anti-scale electric field positive electrode 302 which are oppositely arranged to form a middle electrostatic field, the anti-scale electric field negative electrode 301 is connected with a negative leading-out end of each bionic friction nano-generator 201, and the anti-scale electric field negative electrode 302 is connected with a positive leading-out end of each bionic friction nano-generator 201.

When fluid flows into the device from the water inlet 103, the friction nano generator array 2 is impacted, each bionic friction nano generator 201 can convert the kinetic energy of the water into electric energy, and the electric energy is transferred to the anti-scaling electric field negative electrode 301 and the anti-scaling electric field positive electrode 302 through leads, so that a high-voltage electrostatic field is formed, ions easy to scale are deflected in different directions in a water system under the action of the electric field, and scaling is prevented.
Preferably, the friction nano-generator array 2 is disposed near the water inlet 103, and the placement posture thereof is set to receive the water flow direction with the front surface of each bionic friction nano-generator 201, so that the kinetic energy of the fluid can be collected to the maximum extent.
As shown in fig. 3, the biomimetic friction nano-generator 201 includes: FEP substrate 2011, conductive graphite 2013, PTFE film 2015, foam pad 2012, and foam pad 2012. Specifically, the conductive graphite 2013 is attached to the surface of the FEP base 2011, and the conductive graphite 2013 is connected with a conductive copper sheet 2014. The PTFE film 2015 is also connected with a conductive copper sheet 2014; the sponge pad 2012 is disposed between the conductive graphite 2013 and the PTFE film 2015, so that a gap exists therebetween in a stationary state.

Based on the marine organism kelp sheet structure inspiration, the friction nano generator can be sequentially divided into three layers from top to bottom, wherein the upper layer is made of a PTFE film, the lower layer is made of an FEP film, and the FEP film is covered with a copper film. The middle layer is mainly a spongy cushion and air sealed in the spongy cushion and is used for separating the upper layer electrode material from the lower layer electrode material so that the upper layer electrode material and the lower layer electrode material can be discontinuously contacted and separated to generate charge transfer. When the copper film with the electropositivity and the PTFE film with the electronegativity are contacted and separated with each other, a large amount of charges are accumulated on the surface of the flexible friction nano power generation to form an electrostatic field, and the conversion of the kinetic energy of the fluid to the electric energy of the friction nano power generation is completed.
The preparation materials are as follows: 0.04-0.06 mm of Polytetrafluoroethylene (PTFE) film, 0.08-0.1 mm of Fluorinated Ethylene Propylene (FEP) film, 0.08-0.12 mm of copper film, 0.8-1.2 mm thick sponge cushion and the like.
In a preferred embodiment of the invention, 0.05mm Polytetrafluoroethylene (PTFE) film and 0.1mm Fluorinated Ethylene Propylene (FEP) film, 0.01mm copper film, 1mm thick foam pad, conductive ink, conductive wire, etc. are selected. The structure of the three-layer sandwich structure is similar to a sandwich structure and can be divided into three layers from top to bottom. The upper layer is made of a PTFE film, has electronegativity due to high fluorine content and is used as a negative electrode of the friction nano generator; the lower layer is made of a FEP film with the thickness of 0.1mm, and a copper film is attached to the FEP film and used as a positive electrode of the friction nano generator. The FEP film has better elasticity, and can provide the restoring force of the friction nano generator swinging in the flow field under the action of the fluid; the middle layer is mainly a spongy cushion with the thickness of 1mm and seals the air in the spongy cushion and is used for separating the upper layer electrode material from the lower layer electrode material so that the upper layer electrode material and the lower layer electrode material can be discontinuously contacted and separated to generate charge transfer. When the copper film with the electropositivity and the PTFE film with the electronegativity are contacted and separated with each other, a large amount of charges are accumulated on the surface of the 'sea belt sheet' at the moment, an electrostatic field is formed, and the conversion of the kinetic energy of the fluid to the electric energy of the friction nano generator is completed.
The anti-scaling method comprises the following steps: the bionic friction nano generator is arranged in a waterway system needing scale prevention in an array mode, when fluid flows through, the kinetic energy of the water can be changed into electric energy by the friction nano generator, and the electric energy is transferred to the electrode plate part of the scale prevention electric field by a lead wire, so that a high-voltage electrostatic field is formed. Under the action of the electric field, ions easy to scale can deviate in different directions in a water system, so that the probability of combination of the ions is reduced, and the scaling phenomenon is further reduced. The method is different from the traditional static anti-scaling method, and does not need to additionally add a power supply device outside; and the anti-scaling method of the friction nano generator, which is different from a part of concept forms, needs various combinations of a generator part, an external amplifying circuit part, an anti-scaling electric field part and the like. The friction nanometer generator array designed by the method has been proved to be capable of better collecting electric energy, an external amplifying circuit part is eliminated, and the highly integrated structure undoubtedly improves the application field and reduces the maintenance cost.
Due to the high-efficiency conversion efficiency from fluid kinetic energy to electric energy of the bionic structure and the scientificity of array combination arrangement, the friction nano power generation structure and the anti-scale device provided by the invention can stably provide a voltage of more than 165V for the constructed electric field at the flow speed of 150m/h and the water temperature of 20 ℃, avoid redundant structures such as a high-voltage amplifying circuit and the like, and have high integration. Compared with the traditional electric field anti-scaling scheme, a series of problems of overhigh electric power cost, electric leakage, hurting people, circuit failure and the like are avoided.
The invention also provides an anti-scaling experimental method based on the bionic friction nano-generator, which is realized based on the anti-scaling device based on the bionic friction nano-generator and comprises the following steps:
s1, arranging an anti-scaling device based on the bionic friction nano generator on the test platform;

s3, enabling liquid with easily-scaling ions in the anti-scaling device based on the bionic friction nano generator to circularly flow;
and S4, collecting experimental data based on the data collecting device, and evaluating the anti-scaling effect.
In one embodiment, the data acquisition device comprises a voltage acquisition device connected to the anti-scaling electric field electrode. In another embodiment, the data acquisition device uses an ion concentration measuring instrument, and a detection mechanism of the ion concentration measuring instrument extends into the liquid inside the circulating water tank.
The experimental method of the present invention is further illustrated by the following specific application examples.
