Wherein, the rubber tube 21 is the withstand voltage hose that all has certain flexible length, in order to make and to have the medium of pressure in the pressure chamber 8 all the time, therefore make pressure chamber 8 and the inner chamber intercommunication of flexible pipe 4 through its rubber tube 21, therefore after its flexible pipe 4 receives from gravity to descend, can extrude the medium of inner chamber, and then through the rubber tube 21 with the lasting conveying of medium and pressure to in the pressure chamber 8, guarantee pressure chamber 8 homoenergetic when any and push out its regulating block 7, make and stabilize all the time in the angle of regulation.

Wherein, the bottom of the top cover 14 is provided with a cylindrical top block which is matched with the top end of the communicating hole 15, a liquid conveying groove which is communicated with the rain collecting groove 140 and the pressure maintaining cavity 8 is arranged in the cylindrical top block, the end surface diameter value of the liquid supplementing ball 16 is twice of the end surface diameter value of the liquid conveying groove at the bottom of the top cover 14, in order to prevent the medium in the pressure maintaining cavity 8 from dissipating and causing the phenomenon that the regulating block 7 of the pressure maintaining cavity cannot be pushed out normally, the rainwater is collected by opening the rainwater collection groove 140 on the top cover 14 thereof for the supplement of the medium, meanwhile, a cylindrical top block is arranged at the bottom of the top cover 14, and the liquid supplementing ball 16 is jacked up through the cylindrical top block, so that the rain collecting groove 140 is isolated from the pressure maintaining cavity 8, the medium in the rain collecting groove 140 increases, and further the pressure of the medium increases, so that the medium in the rain collecting groove 140 pushes the liquid replenishing ball 16 and flows into the pressure maintaining chamber 8, and further the replenishment of the medium is completed.

The using method of the invention has the following working principle: firstly, a signal antenna 3 is movably arranged at the top ends of a fixed frame 6 and a transmission rod 70;

lifting the state: injecting a medium continuously through the liquid inlet 5, further increasing the medium in the extension tube 4 continuously through the liquid inlet 5, and then enabling the fixing frame 6 to slide upwards along the side wall of the bracket 2 through the pressure applied to the extension tube 4 until the extension tube 4 pushes the fixing frame 6 to the top of the bracket 2, namely finishing the lifting;

the angle adjusting state is as follows: the medium is continuously filled into the extension tube 4 through the liquid inlet 5, the medium pressure in the pressure maintaining cavity 8 is continuously increased through the diversion hole 9, the adjusting block 7 is further urged to move to the left side (the direction refers to the attached drawing 2), then the adjusting block 7 is caused to move to one side through the adjusting block 7, the adjusting block 7 drives the transmission rod 70 to push out the signal antenna 3, so that the signal antenna 3 has a certain inclination angle, meanwhile, the adjusting block 7 extrudes the limiting plate 10 to move to one side, the limiting spring 11 is further compressed, in the moving process of the limiting plate 10, the limiting ball 12 is clamped into the ball groove on the limiting groove 13 at one side, finally, the signal antenna 3 has a certain inclination angle through the pushing of the adjusting block 7, and meanwhile, the limiting ball 12 is clamped into the ball groove on the limiting groove 13, so that the limiting spring 11 is continuously compressed, therefore, when the liquid inlet 5 is not filled with a medium any more and the pressure of the medium is removed, the medium in the extension tube 4 is always subjected to the pressure through the gravity because the extension tube 4 is influenced by the self-gravity, and the medium with the pressure is conveyed through the rubber tube 21, so that the adjusting block 7 of the extension tube can be always pushed to the position of the limiting plate 10, namely the final inclination angle position of the signal antenna 3;

fixing and medium supplementing: after the fixing frame 6 reaches the bottom, the bottom of the top cover 14 is inserted into the communicating hole 15, the bottom can clamp the liquid supplementing ball 16 by passing through the communicating hole 15, then, after the angle adjustment is carried out, the hydraulic pressure in the pressure maintaining cavity 8 is continuously increased, so that the limiting plate 10 moves to one side, meanwhile, after the position of the limiting plate 10 is separated, the locking contact 18 cannot be blocked by the limiting ball 12, the locking rod 17 is deflected under the action of the locking spring 19, the locking block 20 is pushed to be clamped into the tapered groove on the top cover 14, so that the fixing frame 6 is fixed on the top cover 14 by the locking block 20, then, after the angle adjustment is finished, the telescopic pipe 4 is subjected to gravity falling factors, so that the pressure in the telescopic pipe 4 is extruded, and the medium in the telescopic pipe 4 is conveyed into the pressure maintaining cavity 8 through the rubber pipe 21, the pressure-maintaining cavity 8 is kept under the pressure of the pushing adjusting block 7, then, in the rain process, rainwater is gathered through the rainwater collection groove 140, after a certain amount of rainwater is gathered, the liquid supplementing ball 16 is pushed out under the influence of the medium pressure in the rainwater collection groove 140, then the medium in the rainwater collection groove 140 flows into the pressure-maintaining cavity 8, and then when the medium pressure in the rainwater collection groove 140 is reduced, the liquid supplementing ball 16 is still pushed to the top of the top cover 14 under the influence of the medium pressure in the pressure-maintaining cavity 8, and the rain collection groove 140 and the pressure-maintaining cavity 8 are isolated.

Meanwhile, in the adjusting process, if the pressure of the medium is too large and the moving distance of the limiting plate 10 is increased, the adjusting block 7 can be pushed out to the maximum length by continuously increasing the pressure of the medium, then the limiting ball 12 on the limiting plate 10 can move to the leftmost side of the limiting groove 13 (shown in the direction of the attached drawing 3), then the pressure of the medium of the liquid inlet 5 is removed, the limiting plate 10 can push the limiting ball 12 into the linear groove on the limiting groove 13 under the elastic force of the limiting spring 11 and quickly push the limiting plate 10 to the rightmost side of the limiting groove 13, then the pressure of the medium filled in the liquid inlet 5 is increased, and the operation is carried out according to the steps again.
