[0055] Implementation process:

[0056] like Figure 1-8As shown, when the phased array radar needs to be installed on the cart 54 for transportation, the base 1 is moved to the cart 54, the motor 11 is turned on, the rotor of the motor 11 drives the shaft 9, the cylinder 6, the worm gear 10, the worm 12, and the third spur gear 20 to rotate, and the piston rod 7 on the cylinder 6 is extended, so that the radar body 2 changes from a horizontal state to an inclined state, so as to facilitate the detection of the radar body 2, the third spur gear 20 drives the second spur gear 19 to rotate through the fourth spur gear 23, and the second spur gear 19 drives the two reinforcement columns 14 to move in opposite directions, and the reinforcement columns 14 move toward the column cavity 1. 3, when the T-shaped reinforcement 37 moves to the outside of the column cavity 13, it loses the support of the bottom wall of the column cavity 13, and the T-shaped reinforcement 37 moves downward under the action of its own gravity, and the second glue outlet channel 38 is connected with the first connecting channel 31. The bottom wall of the horizontal section of the T-shaped reinforcement 37 presses down the force-bearing sheet 40 and the rubber spacer 41 to overcome the elastic force of the third elastic member 39 and move downward, thereby releasing the blockage of the first connecting channel 31. When the reinforcement column 14 moves, the rack 17 drives the first spur gear 18 to rotate, and the first spur gear 18 drives the gear shaft 53, the second rotating wheel 52, the transmission belt 51, The first rotating wheel 50, the anti-solidification shaft 48 and the anti-solidification blade 49 rotate, thereby stirring the glue in the storage chamber 30 to prevent the glue from solidifying. The glue flows along the first connecting channel 31 to the second glue outlet channel 38, and the glue flows from the lower end of the second glue outlet channel 38 to the outer wall of the vertical section of the T-shaped reinforcement 37, and then the electromagnet 26 is energized to generate magnetic attraction, and the permanent magnet 25 is attracted by the electromagnet 26, thereby driving the movable seat 22 and the fourth spur gear 23 to overcome the elastic force of the second elastic member 24 and move toward the fixed plate 27, and the fourth spur gear 23 is released from the first elastic member 24. The three spur gears 20 and the second spur gear 19 are meshed, and the two reinforcement columns 14 are retracted into the column cavity 13 under the elastic force of the first elastic member 15 until the T-shaped reinforcement 37 and the side wall of the cart 54 are against each other. The two T-shaped reinforcements 37 clamp the cart 54, so that the base 1 is installed on the cart 54. The glue on the outer wall of the T-shaped reinforcement 37 can make the T-shaped reinforcement 37 and the cart 54 adhere to each other, improving the stability of the connection. If it is necessary to reduce the height of the phased array radar, the motor 11 can be reversed and the piston rod 7 can be shortened to restore the radar body 2 to a horizontal state. Finally, the electromagnet 26 is powered off, and the movable seat 22 is reset along the slide rail 21 under the elastic force of the second elastic member 24, so that the fourth spur gear 23 is meshed with the third spur gear 20 and the second spur gear 19.

[0057] like Figure 1-7As shown in Figures 9 and 10, when the phased array radar needs to be installed on an open container 55 for transportation, the base 1 is moved into the open container 55, the motor 11 is turned on, and the piston rod 7 on the cylinder 6 is extended, so that the radar body 2 changes from a horizontal state to an inclined state, so as to facilitate the detection of the radar body 2, and the second spur gear 19 drives the two reinforcement columns 14 to move in the opposite direction, and the reinforcement columns 14 move out of the column cavity 13 until the force block 43 on the reinforcement column 14 is against the inner wall of the open container 55, and the force block 43 is pushed into the inner wall of the open container 55. In the transmission groove 32, the wedge block 44 pushes the wedge plate 45 upward, so that the glue outlet hole 46 is connected to the first glue outlet channel 34, and the anti-solidification leaf 49 stirs the glue in the storage chamber 30 to prevent solidification. The glue in the storage chamber 30 flows through the first glue outlet channel 34 to the outer wall of the reinforcement column 14, so that the outer wall of the reinforcement column 14 and the inner wall of the open container 55 are bonded, and the two reinforcement columns 14 and the inner wall of the open container 55 are abutted to fix the base 1, and the glue strengthens the connection between the base 1 and the inner wall of the open container 55. The open container 55 can be connected to various suitable vehicles for transportation.

[0058] The present invention can be driven by a motor 11 to enable the base 1 to be quickly and conveniently installed on different carriers. When the base 1 is installed on the cart 54, the two T-shaped reinforcement members 37 can clamp and fix the cart 54, and the connection can be strengthened with the automatically flowing glue, without the need for complicated connection operations with the help of other components. When the base 1 is installed on the convertible container 55, the two reinforcement columns 14 can support the inner wall of the convertible container 55, and the connection can be strengthened with the automatically flowing glue, without the need for complicated connection operations with the help of other components. When the glue flows out, the anti-solidification leaves 49 can automatically stir the glue to prevent the glue from solidifying in the storage cavity 30 and being difficult to flow out.

[0059] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
