Problems solved by technology

This device divides the aircraft into three sections, making the connection between the front section, the middle section and the rear section more complicated, which will affect the original internal structure of the aircraft, making it difficult to achieve an organic unity of the system
Each vertical axis ocean current power generation device has a set of hydraulic system consisting of hydraulic oil tank, plunger pump, hydraulic pipeline and rotary joint. The hydraulic system not only occupies a lot of space inside the aircraft, but once the hydraulic system fails, it will affect the The power generation effect of vertical axis ocean current power generation device and the operating performance and safety of underwater vehicles

specific Embodiment approach 1

[0027] Specific implementation mode 1: see figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 .

[0028] When the underwater unmanned vehicle is sailing, the overall power generation device is installed in the middle of the two propellers outside the tail end of the underwater unmanned vehicle. The linear motor 4 is close to the outer surface of the tail end of the vehicle. In a contracted state, the permanent magnet generator 9 is close to the inside of the tail end of the aircraft, such as image 3 and 4 shown.

[0029] When the underwater unmanned vehicle needs to be charged, the combination figure 2 , 3 , 4 and 5. First, the underwater unmanned vehicle figure 2 The double anchor chain method is fixed, and then the linear motor 4 moves to the designated position away from the tail end of the aircraft. During the motion of the linear motor 4, the pull rod 5 will push the blade 8 and the arm 7 to move together, and the vertical shaft The blades 8 of the wa...

specific Embodiment approach 2

[0031]Specific implementation mode 2: Participate in Figure 6 , Figure 7 and Figure 8 .

[0032] The contraction and expansion of the power generation device adopts such as Figure 6 The structure shown includes smooth ball 10, hydraulic telescopic arm 11, groove 12 and disk 13, wherein the position of disk 13 is the same as that of linear motor 4 in mode 1, and the position of disk 13 and hydraulic telescopic arm 11 is the same as that of mode 1. The function of the linear motor 4 in 1 is the same. combine Figure 6 , 7 and 8 to illustrate in detail, the hydraulic telescopic arm 11 protruding from the inside of the tail end of the aircraft is fixed to the bottom of the disk 13, and is used to control the contraction and expansion of the blades 8 of the power generation device. There is a circle groove 12 on the upper end of the disk 13, and the smooth bead 10 at one end of the pull rod 5 can move circularly in the groove 12. When the vertical axis type water turbine ...

Abstract

The invention belongs to the field of underwater unmanned navigation, and particularly relates to an ocean current power generation device suitable for an underwater unmanned vehicle. According to theocean current power generation device suitable for the underwater unmanned vehicle, a hydraulic power generation device is installed on the tail part of the underwater unmanned vehicle to charge theunderwater unmanned vehicle, blades of the hydraulic power generation device can be driven to rotate by the ocean current, so that an electric generator is driven to generate electric energy and the electric energy is stored in a storage battery, working requirements of the underwater unmanned vehicle are fully met, and the purpose of permanent continuation of the navigation is achieved; the underwater unmanned vehicle can meet electric power required by ocean going detection through the added hydraulic power generation device; when the underwater unmanned vehicle carries out fixed-point detection, the underwater unmanned vehicle can be charged by using the hydraulic power generation device at the same time; the hydraulic power generation device is installed on the tail part of the underwater unmanned vehicle, and the occupied inner space of the underwater unmanned vehicle is small; and the blades of the hydraulic power generation device can be contracted to be attached to the underwater unmanned vehicle, so that the hydraulic power generation device does not affect the navigation and the navigational speed of the underwater unmanned vehicle.

Description

technical field [0001] The invention relates to a charging system for an underwater unmanned vehicle, in particular to an ocean current power generation device suitable for the underwater unmanned vehicle. Background technique [0002] The ocean accounts for 71% of the earth's surface, with a vast area and rich marine resources, but the degree of development and utilization is still very low. Therefore, it is of great significance to explore marine resources. In order to understand the distribution of marine resources, countries have successively conducted research on underwater unmanned aerial vehicles since the late 1950s, and underwater unmanned aerial vehicles can not only detect marine resources, but also be used for military activities, such as intelligence collection, communication relay and mine detection etc. Due to the small size and limited capacity of traditional underwater unmanned vehicles, the energy of the power supply system is limited, so the battery life ...
