Description

Technical Field

[0001] The utility model belongs to the technical field of deep-sea aquaculture equipment, and relates to a device for simulating the change of the inclination angle of a cage movement, in particular to a device for simulating the change of the inclination angle of a cage movement during the filling and exhausting process of a submersible cage movement. Background Art

[0002] When developing deep-sea aquaculture equipment, it is necessary to consider the stability and durability of the aquaculture equipment. Ordinary HDPE cages cannot meet the realistic environment of deep-sea aquaculture, such as strong winds, huge waves, rapids, etc. In view of the characteristics of deep-sea aquaculture, it is particularly important to develop submersible cages suitable for deep-sea aquaculture.

[0003] During the diving and floating process of the cage, the stability of the cage needs to be maintained. It is especially important to keep the speed and inclination of the cage stable during the diving and floating process. How to control the inclination of the cage during the diving and floating process is a very important aspect of the development of deep-sea cages. Utility Model Content

[0004] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a device that simulates the change in the inclination angle of a submersible cage during the filling and exhaust process. The technical problem to be solved by the utility model is: how to simulate the change in the inclination angle of the cage and collect and study the data on the inclination angle during the movement of the submersible cage.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A device for simulating the change in the inclination angle of a submersible cage during the inflation and exhaust process, comprising a cage frame, a plurality of dual-axis inclination sensors fixed on the top of the cage frame, small floats fixed on all sides of the top of the cage frame, large floats fixed on all sides of the bottom of the cage frame, and a drive frame fixed on the bottom of the cage frame, an airflow conveying control component being arranged in the drive frame, and the airflow conveying control component being connected to four small floats and four large floats.

[0007] The working principle of the utility model is: the inclination change of the cage model in the movement process can be monitored in real time through a dual-axis inclination sensor, and then the gas volume inside the large buoys and small buoys at four positions is regulated and changed through an airflow delivery control component, so as to achieve the effect of controlling the inclination size, and because the bottom of the cage frame is a large buoy, the internal capacity of the large buoy is larger than the small buoy at the top of the cage frame, so after the water storage inside the four large buoys is emptied, the cage frame can be exposed to the sea surface, which is convenient for personnel to observe or collect the seafood inside.

[0008] The tops of the four small pontoons and the four large pontoons are fixed with air discharge and inlet valves, the bottoms of the four small pontoons and the four large pontoons are fixed with water discharge and inlet valves, three-way joints are fixed around the cage frame, two of the interfaces of each three-way joint are connected to the corresponding two air discharge and inlet valves, and each three-way joint is connected to the airflow conveying control component.

[0009] By adopting the above structure, the internal gas content and water content of each large and small buoy can be regulated through the cooperation of the air discharge and inlet valves and the water discharge and inlet valves, thereby improving the regulation accuracy and better simulating the change of the inclination angle of the cage.

[0010] The airflow delivery control component includes an air pump fixed in a driving frame and a gas flow meter fixedly connected to the output end of the air pump, the gas flow meter is connected to a Y-shaped air pipe joint, and the air vents at both ends of the Y-shaped air pipe joint are fixedly connected to a three-way control valve, and the remaining valve ports of the two three-way control valves are fixedly connected to a ventilation pipe one, and the four ventilation pipes are all connected to the corresponding three-way joints.

[0011] With the above structure, the gas output by the air pump can be measured by a gas flow meter to assist in the precise control of gas input and output, ensuring the stability and efficiency of the simulation process. The valve direction can be switched and the valve opening can be automatically controlled through two three-way control valves to adjust the gas flow entering each large buoy and small buoy.

[0012] The air pump input end is connected with an air intake pipeline, the other end of the air intake pipeline is fixedly connected with an air intake hopper, and an air ring is fixed outside the air intake hopper.

[0013] By adopting the above structure, the air intake hopper can be exposed to the sea surface through the air ring, and then the air is sucked through the air intake hopper to supply gas to the air pump, ensuring the normal overall gas transportation.

[0014] A high-speed camera is fixed on the cage frame.

[0015] By adopting the above structure, the movement of the cage can be recorded in real time by a high-speed camera, which is convenient for analyzing the movement status of the cage.

[0016] Compared with the prior art, the device for simulating the change of the inclination angle of the cage during the filling and exhaust process of the submerged cage has the following advantages:

[0017] 1. The air flow control component is used to control the amount of gas inside the large and small floats at four positions, so as to control the size of the inclination angle, improve the control accuracy, and better simulate the change of the inclination angle of the cage.

[0018] 2. There is a large float at the bottom of the cage frame. The internal capacity of the large float is larger than the small float at the top of the cage frame. Therefore, after emptying the water inside the four large floats, the cage frame can be exposed to the sea surface, making it convenient for personnel to observe or collect the seafood inside.
