Description

Bionic fish capable of releasing bait Technical Field The application relates to bionic fish equipment, in particular to a bionic fish capable of releasing bait. Background In fishing or fishing activities, nest-forming by throwing baits is a common and direct means of attracting fish. In relatively calm water areas, this approach tends to be relatively efficient and can attract fish to gather. However, the defects are obvious, namely, the cost is high, and obvious resource waste exists. Most of the baits are soaked and sunk to the bottom rapidly after entering water, so that the method mainly attracts the fishes at the bottom layer, the trapping effect on the fishes at the middle and upper layers is greatly reduced, and the applicable fish species and scenes are limited. In addition, the fish attracting means has strong limitation in practical application. In large lakes or open waters such as offshore, the fish distribution is more dispersed, and effective trapping areas are difficult to form by simply throwing the baits, so that the fish trapping effect is limited, a large amount of baits are wasted, and the fishing economic cost is increased intangibly. Meanwhile, the traditional mode only can attract fishes to a fixed area, so that a fisher is restrained at a specific position to perform work, the space flexibility of fishing activities is limited, and the position or range is difficult to dynamically adjust according to actual conditions. Along with the development of science and technology, people begin to try to replace artificial bait throwing by utilizing intelligent equipment such as bionic fish and unmanned aerial vehicle, so as to improve the accuracy and efficiency of fish attracting and overcome the defects of the traditional method. However, on this technical path at present, especially the common design scheme of directly filling bait on the bionic fish body still has a series of structural and functional drawbacks, has restricted its practical effect, mainly shows: First, the design faces a fundamental contradiction between bait carrying capacity and device performance. In order to increase the bait carrying amount of single operation, the bionic fish volume must be enlarged and the power system thereof must be lifted, which not only leads to significant increase in manufacturing cost and energy consumption, but also leads to more complex equipment structure and reduced portability. Secondly, the problems of motion noise and water disturbance caused by the motion noise are particularly remarkable. When the bionic fish with larger volume and stronger power moves in water, obvious mechanical vibration and unnatural flow field fluctuation can be generated, and the abnormal signals are extremely easy to surprise the fish shoal, so that the fish shoal escapes, and the fish shoal runs counter to the fundamental purpose of trapping. Furthermore, the bait release means is mechanical and has limited effectiveness. The bait filled in the bait is usually released through preset holes or a simple mechanism, so that the slow release, diffusion and suspension dynamic process of the bait in a natural water body are difficult to simulate, and the attraction of the bait to fishes in different water layers is still insufficient. However, the existing scheme for attracting fish by utilizing bionic fish has inherent defects due to the structural design, so that the space limitation and efficiency bottleneck of the traditional fish attracting method can be perfectly solved, and new challenges are introduced in practicality, economy and final fish attracting effect. The present application has been made in view of the above-mentioned problems. [ MEANS FOR SOLVING PROBLEMS ] The application aims to provide a bionic fish capable of releasing bait, which is characterized in that a fish attracting device is detachably connected with a middle cabin section in the bionic fish and is in communication control connection with a control unit of the bionic fish so as to control the fish attracting device to release bait for attracting fish, so that the fish attracting device is detachably connected with a bionic fish main body as an independent module, different types of bait cabins or fish attracting devices can be quickly replaced according to different water areas, fish types and operation requirements, and a multifunctional function is realized. This not only improves the versatility of the device, but also reduces the cost of repeatedly purchasing the device for different scenarios. When the fish attracting device is separated from the bionic fish structure, the fish attracting device can avoid excessively enlarging the volume of the bionic fish or increasing the power load of the fish attracting device due to bait filling, is beneficial to keeping the streamline appearance and low-resistance motion characteristics of the bionic fish, ensures that the bionic fish keeps and concentrates on efficient and low-noise swim
