DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] As shown in Figure 1 and Figure 2 The utility model provides a kind of monitoring unmanned aerial vehicle inspection platform on water, including device platform 1, device platform 1 is used to be the role of receiving in one aspect when unmanned aerial vehicle needs to be fixed point to take off, another aspect device platform 1 can add functional unit, for specific functional use.For example, landmark recess is set on device platform 1, so that the footrest of unmanned aerial vehicle is in landmark recess when device platform 1 receives unmanned aerial vehicle, to make the parking of unmanned aerial vehicle more stable.Or wireless charging unit is set in device platform 1, charging area mark is set on the surface of device platform 1, and wireless charging function is realized when the charging docking unit of unmanned aerial vehicle is in charging area mark.

[0023] Two groups of displacement propellers 2 are arranged on the lower surface of device platform 1, the propulsion directions of the two groups of displacement propellers 2 are arranged perpendicular to each other, so that when the two groups of displacement propellers 2 are simultaneously started, the movement in the horizontal direction and the vertical direction is simultaneously performed to drive the overall device to move obliquely, thereby increasing the movement direction of the overall device.

[0024] That is to say, in the device, device platform 1 can start a displacement propeller 2 in a certain direction alone, or can simultaneously start displacement propellers 2 in two directions, and can realize movement in at least eight directions and circumferential rotation by controlling forward rotation and reverse rotation.

[0025] Further, a ring-shaped float 3 is arranged inside the area enclosed by the two groups of displacement propellers 2 below device platform 1, the ring-shaped float 3 is connected with device platform 1, and a plurality of rotating fans 4 are arranged in a circular array on the ring-shaped float 3, the rotation centers of the plurality of rotating fans 4 are all located on a ring-shaped edge line 5, and the ring-shaped edge line 5 is coaxially arranged with device platform 1.

[0026] Since the rotation centers of the plurality of rotating fans 4 are all located on the annular edge line 5, and the annular edge line 5 is coaxially arranged with the device platform 1, when the plurality of rotating fans 4 are turned on to rotate, the device platform 1 can rotate around its own central axis, so as to realize the steering of the device platform 1 and the functional units on the device platform 1, and better match the docking of the unmanned aerial vehicle.

[0027] Further, as Figure 2 Since the device platform 1 is arranged on the water surface, in order to keep the device platform 1 stably placed, the device platform 1 comprises an outer frame 6, the displacement propeller 2 and the annular float 3 are both mounted on the bottom surface of the outer frame 6, and a placing position is arranged in the middle of the outer frame 6, and a docking platform 7 is arranged in the placing position, and a flow gap 8 is arranged between the docking platform 7 and the outer frame 6.

[0028] Meanwhile, in the above embodiment, the device platform 1 is driven to rotate by the plurality of rotating fans, which also means that the angle of the device platform 1 can be turned according to the wave condition of the water surface, so that the device platform 1 can better cope with the wave condition of the water surface.

[0029] When the outer frame 6 in the embodiment is in a working state, the action of the wave on the outer frame 6 generally includes a coupled lateral action and a vertical action, and when the action is applied to the outer frame 6, it is specifically embodied as a lateral propulsion and a vertical lifting of the outer frame 6.

[0030] Therefore, a plurality of buffer members 9 are uniformly distributed in the flow gap 8, the buffer member 9 comprises a guide rod 91, the two ends of the guide rod 91 are both provided with a connecting spring 96, a matching guide column hole 92 is arranged on the side wall of the docking platform 7 along the radial direction of the docking platform 7, the connecting spring 96 at one end of the guide rod 92 is fixedly connected to the inner side wall of the outer frame 6, and the connecting spring 96 at the other end of the guide rod 91 and part of the rod body of the guide rod 91 are located in the guide column hole 92, and the purpose is to eliminate the lateral action of the outer frame 6.

[0031] Of course, the preferred number of the buffer member 9 in the embodiment is 4, that is, in the X-Y plane rectangular coordinate system with the plane of the outer frame 6 as the X-Y plane, the four buffer members 9 are respectively located on the coordinate axes.

[0032] Specifically, when the outer frame 6 generates a lateral action, of course, the lateral action mainly acts on the buffer member 9 in the same direction as the wave transmission direction.

[0033] Since the docking platform 7 and the outer frame 6 are not fixedly connected, when the wave forms a lateral movement on the outer frame 6, the lateral movement of the outer frame 6 can be eliminated by the buffer member 9, which greatly reduces the kinetic energy from the bed bottom to the docking platform 7, thereby reducing the lateral swing value of the device platform 1 and improving the stability of the whole device.

[0034] Specifically, when the lateral action is transmitted to the outer frame body 6, the guide rod 91 of the corresponding wave transmission direction (for example, the X-axis direction) of the buffer 9 moves along the guide column hole 92, and can move until the connecting spring 96 inside the guide rod 91 in the guide column hole 92 contacts the inner end of the guide column hole 92. During this process, it is the process of the outer frame body 6 to eliminate the wave. Of course, the guide rod 91 of the other corresponding buffer 9 on the X-axis is away from the corresponding guide column hole 92, and always does not deviate from the guide column hole 92.

[0035] The buffer 9 on the Y-axis will also be subjected to a lateral action, that is, the guide rod 91 of the buffer 9 on the Y-axis is subjected to a radial force, which pushes the docking platform 7. In order to avoid this situation, the guide rod 91 in the embodiment includes a first rod body 93 and a second rod body 94, and the first rod body 93 and the second rod body 94 are connected by a universal joint 95. The universal joint 95 is mainly a spherical cage universal joint, so that the end of the first rod body 93 is connected to the inner side wall of the outer frame body 6 by the connecting spring 96, and the end of the second rod body 94 is provided with two connecting springs 96. Part of the second rod body 94 and the connecting spring 96 provided at the end thereof are located in the guide column hole 92.

[0036] When the guide rod 91 (on the Y-axis) formed by the first rod body 93 and the second rod body 94 is subjected to a radial force, the universal joint 95 will be deflected, that is, the first rod body 93 and the second rod body 94 will be relatively angularly rotated at the connection. The angular rotation can be multidirectional, for example, angular rotation in the horizontal plane and horizontal rotation in the vertical plane, so as to avoid the situation that the above-mentioned force pushes the docking platform 7. The connection mode of the first rod body 93 and the second rod body 94 can also be used to adapt to the vertical action of the wave.

[0037] It should be noted that the sum of the second rod body 93 and the initial length of the connecting spring 96 in the natural state is greater than the axial length of the guide column hole 92.

[0038] Further, the top surface and the bottom surface of the docking platform 7 are higher than the top surface and the bottom surface of the outer frame body 6 (not shown in the figure). In the embodiment, the top surface of the docking platform 7 can be higher than the top surface of the device platform 1 to avoid water flowing through the overflow gap 8 to overflow on the surface of the docking platform 7.

[0039] Further, a plurality of overflow energy release holes 12 are formed in the side wall of the outer frame body 6, and the overflow energy release holes 12 are arranged in communication with the overflow gap 8. The purpose is also to eliminate the shaking of the overall structure caused by the wave. The outer frame body 6 and the wave elimination area are designed and calculated according to the principle of buoyancy balance to balance the outer frame body 6 in the water.

[0040] The specific working principle is: when the water surface is still, the outer frame body 6 and the overflow gap 8 are balanced with the external water pressure, and the outer frame body 6 does not work. When waves act on the wall of the outer frame body 6, one half of the water can enter the outer frame body 6 through the overflow energy release hole 12, and at the same time, one half of the water can be discharged from the outer frame body 6 through the overflow energy release hole 12, and the remaining half of the kinetic energy is blocked by the wall of the outer frame body 6, so that the surge peak value is weakened, and the total energy is halved. When the wave trough appears, the water pressure in the wave elimination pool is greater than that outside the pool, and half of the water kinetic energy in the pool is transferred to the outside of the pool, forming the effect of peak clipping and valley filling. Because the water tension principle of water kinetic energy transmission changes more and more frequently, the peak clipping and valley filling effect is better, and the relative balance of kinetic energy is automatically formed.

[0041] Among them, the docking platform 7 is provided with a docking area, and an electric control device is arranged below the docking platform 7. The electric control device can be connected with the displacement thruster 2 and the rotating fan 4 through a wire harness to provide power for the two. The electric control device can be arranged at a position in the middle of the annular floating body 3, which is wrapped by a waterproof cover body and has functional units such as wireless charging inside, to provide functional assistance for the docking of the unmanned aerial vehicle.

[0042] The above examples are only exemplary embodiments of the present application and are not used to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements should also be considered to fall within the protection scope of the present application.
