Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of net cage cleaning robots, and in particular relates to a buoyancy center adjusting device of the net cage cleaning robot based on the position of floating materials. Background Art
[0002] Cage aquaculture is one of the important forms of fishery aquaculture. Cage aquaculture is mainly used for marine aquaculture, such as marine fish farming. With the expansion of cage aquaculture, some problems are also accompanied, such as the rapid reproduction of algae, shellfish and other attachments on the surface of the net, which will cause the mesh to be blocked, affecting the exchange of water inside and outside the cage, reducing the dissolved oxygen and food supply, and affecting the growth rate and survival rate of fish. Therefore, cage cleaning robots are needed to complete the work of regular cage cleaning.
[0003] The structure of the cage cleaning robot currently used is as follows: Figure 1 As shown, the robot comprises a main body 01 and a plurality of thrusters 02 arranged on the main body 01, a plurality of brush assemblies 03 for cleaning net clothes are arranged on one side of the main body 01, and a float 04 is also arranged on the main body 01, wherein the float 04 is fixedly connected to the main body 01. Once the float 04 is installed, the buoyancy center position of the entire robot is determined. When the robot needs to switch between a vertical posture and a horizontal posture, it can only rely on the thrusters 02, so that the power consumption of the thrusters 02 required for posture conversion is relatively large. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a buoyancy center adjustment device for a cage cleaning robot based on the position of a floating material.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The main body is symmetrically provided with guide rods along the left and right directions, and the guide rods extend along the vertical direction;
[0008] The floating material and the corresponding guide rod are slidably matched in the vertical direction;
[0009] The main body is provided with a height adjustment component for driving the floating material to move along the guide rod.
[0010] Preferably, the height adjustment assembly comprises a lead screw extending in the vertical direction, and the axial ends of the lead screw are rotatably matched with the body;
[0011] The floating material is provided with a through hole penetrating in the vertical direction, and a screw nut threadably matched with a corresponding screw is provided in the through hole;
[0012] The main body is provided with a driving member for driving the lead screw to rotate.
[0013] Preferably, screw seats are provided at both ends of the screw, the screw seats are fixedly provided on the body, and the screw and the screw seats are rotatably matched;
[0014] One end of the lead screw passes through the lead screw seat and is connected to the corresponding driving member.
[0015] Preferably, the driving member comprises a stepper motor fixedly mounted on the body, and a driving pulley is coaxially fixedly mounted on the end of the output shaft of the stepper motor;
[0016] One end of the lead screw passes through the lead screw seat and is coaxially fixedly connected to the driven pulley;
[0017] A transmission belt is connected between the corresponding driving pulley and the driven pulley.

[0019] The distance sensor is connected to a controller, and the controller is connected to a stepping motor.
[0020] The beneficial effects of the utility model are:
[0021] When the net cage cleaning robot switches from a vertical posture to a horizontal posture, the stepper motor controls the lead screw to rotate, so that the floating material moves downward, so that the center of buoyancy coincides with the center of gravity. In this process, the propeller uses a smaller power operation according to the existing technology to cooperate, and the conversion from vertical to horizontal posture can be achieved; when the net cage cleaning robot switches from a horizontal posture to a vertical posture, the stepper motor controls the lead screw to rotate, so that the floating material moves upward, so that the center of buoyancy is away from the center of gravity. In this process, the conversion from horizontal to vertical posture can be achieved without a propeller. Therefore, the setting of the floating material with adjustable height in this application reduces the power consumption of the required propeller during the posture conversion process.

[0037] The body 01 is symmetrically provided with guide rods 1 along the left-right direction, and the guide rods 1 extend along the vertical direction;
[0038] The floating material 04 is slidably matched with the corresponding guide rod 1 in the vertical direction;
[0039] The main body 01 is provided with a height adjustment assembly for driving the floating material 04 to move along the guide rod 1 .
[0040] Preferably, the height adjustment assembly comprises a lead screw 2 extending in the vertical direction, and the axial ends of the lead screw 2 are rotatably matched with the body 01;
[0041] The float material 04 is provided with a through hole penetrating in the vertical direction, and a screw nut threadedly matched with the corresponding screw 2 is provided in the through hole;

[0043] Preferably, screw seats 21 are provided at both ends of the screw 2, the screw seats 21 are fixedly provided on the body 01, and the screw 2 and the screw seats 21 are rotationally matched;
[0044] One end of the lead screw 2 passes through the lead screw seat 21 and is connected to a corresponding driving member.
[0045] Preferably, the driving member comprises a stepper motor 3 fixedly mounted on the body 01, and a driving pulley 4 is coaxially fixedly mounted on the end of the output shaft of the stepper motor 3;
[0046] One end of the screw 2 passes through the screw seat 21 and is coaxially fixedly connected to the driven pulley 5;
