Problems solved by technology

During the rotation of the oloid body, the speed at a certain position decreases instantaneously and there is a freeze, and the rotation speed is unstable
[0010]2. When the speed of the machine is low and the machine freezes, if there is algae entanglement at this time, it is very easy to cause the algae removal machine to stop working and appear "crash". Thus causing secondary pollution to the waters where a large number of algae removal machines are put in
In the case of a large number of algae removal machines deployed in territorial waters, the troubleshooting of "dead machines" has increased a lot of maintenance costs and difficulties
[0011]3. The algae removal machine is driven by a single motor without speed compensation function, so it is difficult to achieve high stability of OLOID body output speed
[0012]4. Although the oloid body with the standard center distance has a compact structure, the amount of gas exchange with the water body is small

Embodiment 1

[0034] Take the single servo motor OLOID algae removal machine as an example, such as figure 1 As shown, the OLOID algae removal machine includes servo motor 1, sleeve coupling 2, connection block 3, fork 4, OLOID body 5, fork 6, connection block 7, sleeve coupling 8, and connecting rod 9 , frame 10, servo motor controller 11.

[0035] Technical scheme of the present invention comprises the steps:

[0036] 1. Study the working principle and structural composition of OLOID algae removal machine, deduce and summarize the motor input speed ω of OLOID 1 with the output velocity ω of the OLOID volume 2 relationship between.

[0037] The OLOID body is a special geometric structure discovered by the German mathematician Paul Schatz in 1929. OLOID cleverly uses the principles of fluid mechanics to avoid resistance in the largest range during fluid motion, forming a unique fluid trajectory. An Oloid body is formed by overlapping convex hull skeletons formed by two circles with equa...

Embodiment 2

[0057] In this embodiment, an anti-winding OLOID algae removing machine driven by a servo motor is designed by using the optimal design method for the minimum speed of the anti-winding algae removing machine in the first embodiment.

[0058] In this embodiment, the servo motor is selected as the driving device, and when the rotation reaches the minimum speed position, the minimum speed is increased to prevent winding. By setting the servo motor at a constant speed, the output speed of the OLOID is obtained by calculation analysis and computer simulation methods, and the servo motor is analyzed and debugged so that the algae remover can compensate the rotation speed when a certain speed reaches the minimum position, and as much as possible Keep the rotation at a constant speed to ensure that the rotation speed reaches the level that can effectively grind the seaweed. The redesign calculates the center distance of the oloid, increases the exchange volume of the water body, impro...

Embodiment 3

[0072] In this embodiment, an anti-winding OLOID algae removing machine driven by double servo motors is designed by using the optimal design method for the minimum speed of the anti-winding algae removing machine in the first embodiment.

[0073] In this embodiment, two servo motors are selected, and the speed can be controlled through the characteristics of the servo motors. When the minimum speed appears when the oloid rotates at a certain position, the speed of rotating to this position is increased through the control of the servo system. Because the servo motor is a typical closed-loop feedback system, the reduction gear set is driven by the motor, and its terminal, the output end, drives a linear proportional potentiometer for position detection. The potentiometer converts the rotation angle coordinates into a proportional voltage and feeds it back to the control circuit board. , the control circuit board compares it with the input control pulse signal, generates a corre...

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to an anti-winding OLOID algae removal machine driven by double servo motors. Background technique [0002] There are many rivers, lakes and seas on the earth. In recent years, the algae flooding has not only affected the water landscape and the normal growth of aquaculture, but also the algal toxins produced by the algae can cause liver cancer in the human body, posing a threat to the human living environment. [0003] Algae removal methods are usually divided into two categories: direct methods and indirect methods. Direct methods include physical, chemical and biological methods. Physical methods include mechanical algae removal, water flushing and deep water aeration. Biological methods include light source control methods, algae production, and direct control of cyanobacteria by using filter-feeding fish. Indirect methods mainly include watershed countermeasures and lake...
