As shown in fig. 1, an unmanned aerial vehicle medicine box for preventing liquid medicine sloshing comprises: the medical kit and prevent shaking the subassembly two parts.
As shown in the attached figures 2-3, the medicine box comprises a box body 1, a water inlet 2 and a water outlet 3. The medicine chest is flat, the bottom is arc-shaped, and the upper end and the lower end of the transverse side of the medicine chest are bevel surfaces inclined at 45 degrees, so the medicine chest is U-shaped in a top plan view, the medicine chest is made of modified high-density polyethylene, the shape of the medicine chest is changed, the medicine liquid moves to impact the side surface of the box body 1, the angle deviation is caused, the spinning is formed, and the sloshing load is distributed and weakened to a certain extent. The water inlet 2 is arranged above the box body 1 in an inclined mode, and the water outlet 3 is arranged at the downward protruding end of one side of the bottom of the box body 1. Wherein, the water inlet 2 and the water outlet 3 are both provided with external threads, the water inlet 2 is covered with the sealing end cover, and the water outlet 3 is connected with the spraying system.
As shown in fig. 2, the anti-sloshing assembly includes: the floating partition plate 4, the fixed clamping groove 5, the buoy 6 and the rigid rope 7. Wherein, the floating partition plate 4 floats on the upper liquid level of the liquid medicine, the shape of the edge of the periphery is the same as the shape of the inner cavity of the box body 1, a preset gap is left between the floating partition plate 4 and the inner cavity of the box body, and a plurality of uniformly arranged mesh 401 structures are distributed on the floating partition plate 4; the meshes 401 are in a circular truncated cone shape, the side close to the liquid level is the lower bottom surface of the circular truncated cone, the side close to the air is the upper bottom surface of the circular truncated cone, and when the liquid medicine moves through the meshes 401, the liquid medicine collides and spins due to the change of the size of the channels of the meshes 401, so that kinetic energy is consumed; the cylindrical fixing clamping grooves 5 are fixedly arranged at four corners of the box body 1 and are in a cylinder shape, and a sliding gap with the preset size of 5-10 mm is arranged at one side of diagonal connecting lines of the four fixing clamping grooves 5; the buoy 6 is a hollow sphere made of polytetrafluoroethylene and is placed inside the fixed clamping groove 5; the four buoys 6 arranged inside the fixed clamping groove 5 are connected with the floating partition plate 4 arranged outside the fixed clamping groove 5 through the rigid rope 7 through sliding gaps.
The diameter of the ball body of the floating barrel 6 is slightly smaller than that of the cylinder of the fixed clamping groove 5, so that the floating barrel 6 is allowed to freely float in the fixed clamping groove 5 and change along with the liquid level change of the liquid medicine together with the floating partition plate 4. Because the sectional area of the fixed clamping groove 5 is far smaller than that of the box body 1, and the liquid medicine exchange between the fixed clamping groove 5 and the box body 1 is relatively small, the liquid medicine in the fixed clamping groove 5 moves relatively independently, and the shaking degree of the liquid medicine in the box body 1 can be ignored. The floating partition plate 4 is fixed in the middle of the medicine chest by the limit of the fixed clamping groove 5, and the position is kept unchanged.
The floating partition 4 and the fixing groove 5 may be made of high density polyethylene by an integral molding process, but not limited thereto, the floating partition 4 and the fixing groove 5 need to have excellent properties such as light weight, high mechanical strength, and chemical resistance.
Preferably, the floating partition plate 4 is a conical partition plate 403 which is an inverted quadrangular pyramid without a bottom surface, wherein the vertex of the quadrangular pyramid is positioned below the liquid level of the medicine, and the bottom surface is positioned above the liquid level; the included angle between the side face and the bottom face of the rectangular pyramid is 30-45 degrees. The inner side and the outer side of the side face of the rectangular pyramid are respectively provided with a plurality of grid plates 403a forming an included angle of 45-60 degrees with the inclined plane, and the grid plates 403a are provided with a plurality of mesh 401 structures. And the fixed point between the rigid rope 7 and the floating clapboard 4 is the middle part of the inclined edge of the quadrangular pyramid shape close to one side of the bottom surface. The floating partition plate 4 is designed into a quadrangular pyramid shape, and the grid plate 403a is added, so that on one hand, the free movement of the liquid medicine can be further limited, the movement speed of the liquid medicine is reduced, on the other hand, the medicine box is divided into a plurality of small areas, the volume change area of the liquid medicine is concentrated at the middle position of the box body 1, and the change degree of the gravity center is reduced.
In order to further understand the technical scheme, the working principle of the method is briefly explained as follows: the floating partition plate 4 is fixed in the middle of the medicine chest by the limit of the fixed clamping groove 5, and the horizontal position is kept unchanged. The positions of the float bowl 6 and the floating partition 4 are changed in the vertical direction together with the liquid level of the liquid medicine. When the unmanned aerial vehicle accelerates to take off, suddenly stops and turns, and liquid medicine moves, the liquid medicine is limited by the floating partition plate 4 and the mesh structure, and is forced to spin and flow around, so that kinetic energy in the liquid medicine is consumed; when the liquid medicine moves through the mesh 401, collision and spin occur due to the change of the size of the channel of the mesh 401, and kinetic energy is consumed; the floating partition plate 4 is designed into a quadrangular pyramid shape, and the grid plate 403a is added, so that on one hand, the free movement of the liquid medicine can be further limited, the movement speed of the liquid medicine is reduced, on the other hand, the medicine box is divided into a plurality of small areas, the volume change area of the liquid medicine is concentrated at the middle position of the box body 1, and the change degree of the gravity center is reduced. Thus, the function of preventing the sloshing of the liquid medicine is realized.
It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
