[0014] The skeleton body provided by the above embodiment of the present application is a basic component, which is made by injection molding or 3D printing, and the process is controllable and convenient; in order to form the installation and debugging of the working structure of the skeleton body, a cutout can be formed on the outer surface of the corresponding position, and a plug can be embedded in the outer surface to solve the problem; at the same time, the monitor device is not externally hung, which shows that the appearance is simple and reliable.

[0015] Figure 2 The figure is a schematic diagram of the internal working component structure of the underwater walking positioning monitor according to the embodiment of the present application; the shaft flow water turbine 2 (see Figure 3 ) embedded in the middle of the water flow channel in the figure is used to form a silent forward drive without water bubbles; the rudder combination composed of 31, 32 and 33 forms a rudder to realize the adjustment of the left and right positions underwater; the step motor 31 with a reducer is embedded on one side of the water channel to generate a rotating force, which acts on the rudder 33 through the rotation of the elastic rotating shaft 32 to form the operation of the yaw of the underwater walking monitor to complete the position adjustment of the underwater circular arc walking. The horizontal rudder composed of 41 and 42 forms a horizontal rudder to realize the adjustment of the position underwater; the motor and the harmonic combination (see Figure 4 ); the part 41 is embedded on one side of the water channel to generate a rotating force, which acts on the horizontal rudder to form the operation of the position underwater of the underwater walking monitor, including the adjustment of the diving depth. The figure 51, 52 and 53 are injected into the skin in a "needle tube" manner (see Figure 4), the density of the underwater walking positioning monitor is monitored to change the position underwater, including the cooperation of the horizontal rudder, including rising to the water surface; wherein, on both sides of the water flow channel, there are open or semi-closed rectangular tubes for the sliding block 51 to pass through the ball screw driven by the combination of the motor and the harmonic reducer in the plug block, to form the front extrusion of seawater, and to generate negative pressure in the rear closed cavity, that is, to change the position underwater in the way of changing the density of the underwater walking positioning monitor; here, the motor and harmonic combination for driving the ball screw are included in the end cap 51; it is necessary to meet the rubber fixing and anti-seepage treatment of the end cap in the tube, and at the same time, the outer edge of the sliding block and the center hole of the ball screw are also treated with rubber to prevent seepage.

[0016] Figure 3 The figure shows that it is composed of a fixed outer ring 21, a water machine support frame 22, and an inner ring blade group 23; there is a ring-shaped E structure composed of silicon steel sheets in the outer ring, which is used for coil winding to form a rotating magnetic field. The water machine support frame is embedded on both sides for supporting the rotor part; the inner ring of the rotor part is adhered with a magnet for the interaction of the outer ring rotating magnetic field and the internal magnetic field of the magnet to form the necessary condition for rotation; and the water machine blades are welded inside the inner ring of the rotor part to connect the internal shaft rotation of the rotor; there are needle rollers on both sides of the rotating shaft to form a support rotating body to complete the efficient operation of the water machine.

[0017] According to the axial flow water machine structure provided by the above-mentioned embodiment of the application, the axial flow water machine is installed in the middle of the water channel; it appears in an embedded way, which is simple and reliable; that is, the axial flow water machine and the horizontal rudder realize the complete control function of the diving depth of the underwater vehicle.

[0018] Figure 4The skeleton body part of the underwater walking positioning monitor of the embodiment of the present application is anatomized and equipped with an equipment schematic diagram; as shown in the diagram, in the skeleton main body 1, there is an axial flow water channel 11 for bubble-free clear sound propulsion of the axial flow water machine; the motor set 31 with a reducer at the front end is used to realize the horizontal swing operation of the monitor by using the elastic shaft 32 and the rudder 33. In order to control the longitudinal size, the motor set 31 is inserted into the hole at one side of the front part of the water channel, and the elastic shaft 33 is connected with the rudder to drive the shaft body fixed above the shaft to ensure that the underwater vehicle moves in the direction of the circular arc. Similarly, in order to control the longitudinal size, the step motor and the harmonic reducer combination 41 are inserted into the hole at one side of the rear part of the water channel and are connected with the horizontal rudder 42 to drive the shaft body of the horizontal rudder to rotate, so as to ensure that the underwater vehicle is suspended at a determined position underwater. The work of extruding the internal seawater is completed by the 51, 52 and 53 sets; in the space opened or semi-opened 12, the step motor and the harmonic reducer embedded body in the fixed baffle set 51 provide a rotating torque acting on the ball screw shaft; the sliding blocks in contact with the inner wall of the chamber on the two sides and four sides form the extrusion and discharge of the seawater at one end of the opening; due to the negative pressure space formed at the back during the extrusion of the sliding blocks, the density change of the underwater vehicle in the form of drainage and negative pressure is formed to achieve passive suspension in water.

[0019] As for the power system, lithium batteries can be installed on the two sides of the abdomen, and a photovoltaic battery set is covered on the upper part for charging the lithium batteries when the water surface rises or charging the lithium batteries after floating to inform the patrol ship to charge; here, the principle is simple, and thus will not be described here.

[0020] In summary, the embodiment of the present application, an axial flow imitated rainbow fish underwater walking positioning monitor, has obvious simulation effect; that is, on the water surface, the observation of the submarine sonar detection including the underwater deep part of the ship has a great deceptive effect due to the shape characteristics. The main parts are prepared by injection molding or 3D printing process, and the light weight structure is well optimized, and the structure is simple and the cost is well controlled.

[0021] The front motor rudder set embedded in the skeleton body and the rear horizontal rudder are embedded in the two sides of the water channel without external hanging, so that the height size is controlled and does not appear bloated. Among them, the elastic shaft of the rudder at the front end of the axial flow water channel is driven; and the motor and the harmonic reducer inside the end cap drive the ball screw on the two sides, which also ensures the longitudinal size; in general, the anti-leakage treatment of the outer part of the rectangular sliding block and the ball screw hole is an ideal operation, which also makes the overall size more compact.

[0022] The injection molding or 3D printing / injection molding component axial flow imitated rainbow fish underwater walking positioning monitor is drawn according to the actual size, which can be refined to guide production; and can further promote the popularization and application of the unmanned underwater vehicle technology.
