Description

Technical Field

[0001] The invention belongs to the technical field of artificial fish nest production, and in particular relates to an intelligent mobile artificial fish nest experimental platform for fish with sinking eggs. Background Art

[0002] With the extensive construction of water conservancy and hydropower projects in my country in recent years, nearly 100,000 dams have been built in major river basins in my country to undertake functions such as water supply, power generation, flood control and irrigation. At the same time, the construction of dams has also had a great impact on the ecological environment of fish, hindering the reproduction and development of fish to a certain extent. Due to the differences in the reproductive habits of various types of fish, the factors affecting the decline of their resources are also different. Therefore, it is necessary to formulate specific resource conservation technologies based on the characteristics of fish spawning and reproduction. Among them, the spawning grounds of fish with sticky eggs have been sharply reduced due to the influence of human activities such as sand dredging, bank protection and hydrological regulation in the reservoir area. In order to protect the reproduction and development of fish with sticky eggs in the reservoir area, it is particularly important to carry out the construction of artificial fish nests for fish with sticky eggs and to study the bearing effects of artificial fish nests made of different materials;

[0003] Artificial fish nests refer to fish protection facilities set up in specific waters that use artificial means to simulate an ecological environment suitable for fish spawning and reproduction. They are widely deployed in fish spawning areas to restore fish proliferation according to the reproductive habits of different types of fish. Currently, the widely used artificial fish nests can be divided into natural plant fish nests, artificial plant fish nests and other fish nests according to different materials. The materials used mainly include duckweed, palm flakes, water hyacinth, dicranopteris, polyethylene, polypropylene matrix materials and artificial waste such as plastic bottles, bicycle tires, etc. Artificial fish nests can be divided into mesh artificial fish nests, floating frame artificial fish nests, fish nest bricks, etc. according to different structures;

[0004] Traditional artificial fish nests currently have the following defects:

[0005] First, traditional artificial fish nests are mainly suspended and parallel, and lack underwater artificial fish nest construction methods for the eggs of sticky and sinking fish;

[0006] Second, fish with sluggish eggs are greatly affected by changes in river and lake water levels and underwater topography caused by dam flooding. Traditional artificial fish nests lack the ability to move underwater in multiple directions and over long distances;

[0007] Third, traditional artificial fish nests are mainly for fish with drifting eggs, and the selected attachment matrix materials may not be suitable for fish with sinking eggs;

[0008] Fourth, traditional artificial fish nests do not have the experimental conditions for selecting suitable substrate materials for spawning and observing spawning behavior of fish with sinking eggs. Summary of the invention

[0009] The purpose of the present invention is to solve the problems in the background technology and to provide an intelligent mobile artificial fish nest experimental platform for fish with sinking eggs.

[0010] The technical solution adopted by the present invention is as follows:

[0011] The invention discloses an intelligent mobile artificial fish nest experimental platform for fish with sticky and sinking eggs, comprising an artificial fish nest bed and an intelligent mobile base. The artificial fish nest bed is a field-shaped structure, with buoyancy cylinders on four sides and an experimental observation camera in the middle. A group of Mecanum wheels are respectively installed at four corners of the intelligent mobile base. An omnidirectional mobile motor, a stable support motor, an intelligent control console, a magnetic plate, an underwater camera system and a telescopic hinge are loaded on the intelligent mobile base. The telescopic hinge is used for connecting the artificial fish nest bed and the intelligent mobile base.

[0012] The design of artificial fish nests that can be placed on the bottom of the water for a long time makes up for the current lack of protective measures for sinking egg fishes and provides a suitable spawning place for sinking egg fishes.

[0013] The four underwater Mecanum wheels on the intelligent mobile base can control the free movement of the artificial fish nest underwater, enabling the artificial fish nest to move underwater in multiple directions and over long distances, thus weakening the effects of changes in river and lake water levels and underwater terrain caused by dam discharge on the growth and development of sticky fish eggs.

[0014] Preferably, the artificial fish nest bed is composed of steel sheets, and the buoyancy tube is made of polystyrene.

[0015] Preferably, the artificial fish nest bed is connected to the buoyancy tube via a metal hook, and the number of the buoyancy tubes is several and evenly arranged on the four sides of the artificial fish nest bed to provide buoyancy for the artificial fish nest bed.

[0016] Preferably, there are four magnetic plates, which are symmetrically arranged at the four corners of the top surface of the intelligent mobile base.

[0017] Preferably, the magnetic plate is made of SUS304, and has an adsorption distance of 25cm-50cm, and is used to assist the safe landing of the artificial fish nest bed.

[0018] Preferably, a wireless network is provided inside the intelligent console for connecting to a control terminal of the intelligent console.

[0019] Preferably, the underwater camera system and the experimental observation camera are both equipped with a 316L stainless steel watertight casing, the camera pan can rotate 360° horizontally, and the vertical viewing angle is 0°-90°. The front end of the intelligent mobile base is equipped with a satellite positioning system for real-time coordinate picking and underwater terrain monitoring. The underwater camera system performs real-time coordinate acquisition during underwater terrain monitoring, and the staff performs remote control and image transmission through the intelligent console.

[0020] Through the underwater camera system and the experimental observation camera dual camera system, real-time observation of the underwater environment, the attachment of fish eggs to the artificial fish nest bed, and the spawning behavior of fish are carried out to explore the changes in the attachment status of fish eggs and the laws of fish spawning behavior, providing more theoretical basis for the protection of spawning grounds of sticky egg fish.

[0021] Preferably, the intelligent mobile base has a built-in waterproof colloid battery as the power supply of the base, and the waterproof colloid battery is a 12V200Ah colloid battery.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. The artificial fish nest design that can be placed at the bottom of the water for a long time makes up for the lack of protection measures for fish with sticky and sinking eggs, and provides a suitable spawning place for fish with sticky and sinking eggs;

[0024] 2. The four underwater Mecanum wheels of the intelligent mobile base can control the free movement of the artificial fish nest underwater, so that the artificial fish nest has the function of multi-directional and long-distance underwater movement, which weakens the impact of changes in river and lake water levels and underwater terrain changes caused by dam flood discharge on the growth and development of sticky fish eggs;

[0025] 3. Through the design of four experimental modules of the artificial fish nest bed, multi-condition comparative experiments can be carried out on the matrix materials for fish egg attachment, and the suitable spawning environment for fish with sticky and sinking eggs can be screened out, thus optimizing the protective effect of the artificial fish nest on sticky and sinking fish eggs;

[0026] 4. Through the underwater camera system and the experimental observation camera dual camera system, real-time observation of the underwater environment, the attachment of fish eggs to the artificial fish nest bed, and the spawning behavior of fish is carried out to explore the changes in the attachment status of fish eggs and the laws of fish spawning behavior, and provide more theoretical basis for the protection of spawning grounds of fish with sticky eggs.

[0030] Embodiment 1:

[0031] Reference Figure 1 , an intelligent mobile artificial fish nest experimental platform for fish with sticky eggs, comprising an artificial fish nest bed and an intelligent mobile base 8, the artificial fish nest bed is a field-shaped structure, the field-shaped structure is divided into four areas, namely a natural plant experimental area 1, an artificial plant experimental area 2, a sand and gravel experimental area 3 and an artificial waste experimental area 4, the natural plant experimental area 1 uses natural plants such as fir, reed, and duckweed, the artificial plant experimental area 2 uses artificial algae or other artificial synthetic materials, the sand and gravel experimental area 3 uses sand, pebbles and other materials, and the artificial waste experimental area 4 uses discarded cans, tires and other materials, and is preferably arranged in the waters where the original spawning grounds are distributed and are now damaged;

[0032] The four sides of the artificial fish nest bed are loaded with buoyancy cylinders 5 made of polystyrene. The number of the buoyancy cylinders 5 is adjusted according to the weight of the artificial fish nest bed, so that the artificial fish nest bed can be suspended in the river.

[0033] An experimental observation camera 12 is arranged in the middle of the artificial fish nest bed, which is connected to an operation box on the shore through an umbilical cable, so that an operator can observe the fish egg attachment condition and fish spawning behavior of the artificial fish nest bed in real time through the display screen of the operation box.

[0034] Embodiment 2:

[0035] The Mecanum wheels 10 used in the intelligent mobile base 8 can realize forward movement, lateral movement, oblique movement, rotation and various combined movement modes, so that the entire system can move accurately on the riverbed.

[0036] The underwater camera system 9 can collect the position coordinate values ​​of the current artificial fish nest, the riverbed topography, and the position coordinate values ​​of the execution terminal in real time.

[0037] The intelligent control console 7 mainly integrates the tire locking system, the travel drive system and the information transmission system. It receives the command information of the control terminal through wifi and sends instructions to the intelligent mobile base 8, including the locking and unlocking of the Mecanum wheel 10, the travel path and speed, and the magnetic direction of the magnetic plate 11.

[0038] The tire locking system uses a relay to energize the mechanical device to achieve the purpose of wheel locking. The system uses the 8550 transistor, a switching PNP transistor, which allows the system to lock and open the Mecanum wheel 10 according to instructions, realizing the free switching of the artificial fish nest moving and fixed on the river bottom.

[0039] The travel drive system controls the switch of the omnidirectional mobile motor and performs multi-directional movement of the base according to the instructions. The intelligent control console 7 sends the received movement speed, movement end point coordinate value and execution time to the motion solution unit of the travel drive system, and sends the target point coordinate value to the travel control unit of the travel drive system for real-time adjustment to avoid the situation where the running direction is incorrect.

[0040] The information transmission system connects the intelligent control console 7 with the cloud information platform, transmits the operating status of the artificial fish nest in real time and issues instructions to each module of the intelligent control console 7.

[0041] The main body 8 of the intelligent mobile base has a built-in waterproof colloid battery as the power supply of the base, which is replaced every two weeks. The power supply is turned off when the artificial fish nest is stationary. It is only in operation when the artificial fish nest bed is replaced or needs to be moved to ensure that the power supply supports the long-term operation of the intelligent base.

[0042] Embodiment 3:

[0043] The artificial fish nest bed is connected to the intelligent mobile base 8 via the telescopic hinge 6 , and the intelligent mobile base 8 lowers the artificial fish nest bed to the bottom of the water via the telescopic hinge 6 .

[0044] Four magnetic plates 11 are installed on the upper surface of the intelligent mobile base 8. Through the start-up instruction of the telescopic hinge 6, the magnetic plates 11 are energized to generate adsorption force on the artificial fish nest bed, thereby assisting the safe docking of the artificial fish nest bed with the intelligent mobile base 8.

[0045] Embodiment 4:

[0046] When the experimental design time is reached, the telescopic hinge 6 is extended to make the artificial fish nest naturally float to the water surface, the connecting hook lock between the artificial fish nest bed and the telescopic hinge 6 is loosened, and a new artificial fish nest bed is replaced and lowered to the bottom of the water to conduct a new set of working condition experiments.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
