Abstract
The invention relates to an oil drive type telescopic antenna. The oil drive type telescopic antenna comprises a fixed rod and a telescopic rod component, wherein the fixed rod is a semi-enclosed hollow rod piece, the inner wall of the hollow rod piece is provided with a first bulge ring and a second bulge ring, a floating plug is arranged between the first bulge ring and the second bulge ring, and an air pressure cavity is arranged between the closed end of the fixed rod and the floating plug; the telescopic rod component comprises N mutually sleeved telescopic rods, the telescopic rods are semi-enclosed hollow rods, the opening end of the first telescopic rod is inserted into the opening end of the fixed rod, the opening end of the first telescopic rod is provided with an annular limit bulge and the annular limit bulge is matched with the opening end of the fixed rod, so as to perform sliding limit on the first telescopic rod; damp oil is filled between the second bulge ring of the fixed rod and the opening end of the fixed rod, and the closed end of the fixed rod is further provided with an air faucet; the damp oil is pushed to extend the antenna by the expansion of an air chamber, and the expansion of the antenna can be realized by a general air cylinder.
Description
Technical field
The present invention relates to a kind of oily dynamic formula telescopic antenna, belong to satellite antenna field.
Background technology
Traditional telescopic antenna is manual type, and what during expansion, needs were artificial carries out pull to antenna, on market, has a kind of electrically driven (operated) telescopic antenna now, and it is larger that this antenna is affected by weather environment, and failure rate is higher.
Summary of the invention
The technical problem to be solved in the present invention is: overcome antenna in prior art and launch trouble, and hold flimsy technical problem, a kind of novel oily dynamic formula telescopic antenna is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of oily dynamic formula telescopic antenna, comprise fixed lever and telescopic rod assembly, described fixed lever is semi-enclosed hollow rods, inwall in hollow rods is provided with the first protruding ring and the second protruding ring, between described the first protruding ring and the second protruding ring, be provided with float-valve plug, between the blind end of fixed lever and float-valve plug, be provided with atmospheric pressure cavity, described telescopic rod assembly comprises N the telescopic rod of socket mutually, telescopic rod is all semi-enclosed hollow stem, the openend of described first telescopic rod is inserted in the openend of fixed lever, openend at first telescopic rod is provided with annular stop projection, described annular stop projection coordinates with the openend of fixed lever, to first telescopic rod, slide spacing,
Between the second protruding ring of described fixed lever and the openend of fixed lever, be perfused with damping oil, on the blind end of described fixed lever, be also provided with valve.
As further innovation of the present invention, on the wall between described the first protruding ring and fixed lever blind end, be also provided with auxiliary exhaust ports, in described auxiliary exhaust ports, by relief valve, be connected with auxiliary gas cylinder, described auxiliary gas cylinder is open circles tubulose, in described auxiliary gas cylinder, be provided with auxiliary piston, at auxiliary piston, between the end face of air inlet one side and auxiliary piston, be provided with diastole spring dorsad.
The invention has the beneficial effects as follows:
The present invention stretches antenna by the expansion promotion damping oil of air chamber, only need common inflator just can realize the flexible of antenna, without any need for oil pressure pump or electric drive assembly, easy to operate, and can realize the control to antenna stretching speed by changing the parameter of relief valve in the present invention.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is generalized section of the present invention.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, the present invention is a kind of oily dynamic formula telescopic antenna, comprise fixed lever 1 and telescopic rod 2 assemblies, fixed lever 1 is semi-enclosed hollow rods, inwall in hollow rods is provided with the first protruding ring 3 and the second protruding ring 4, between the first protruding ring 3 and the second protruding ring 4, be provided with float-valve plug 6, between the blind end of fixed lever 1 and float-valve plug 6, be provided with atmospheric pressure cavity, telescopic rod 2 assemblies comprise one with fixed lever 1 telescopic rod 2 of socket mutually, telescopic rod 2 is all semi-enclosed hollow stem, the openend of telescopic rod 2 is inserted in the openend of fixed lever 1, openend at telescopic rod 2 is provided with annular stop projection 5, annular stop projection 5 coordinates with the openend of fixed lever 1, to telescopic rod 2, slide spacing,
Between the second protruding ring 4 of fixed lever 1 and the openend of fixed lever 1, be perfused with damping oil, on the blind end of fixed lever 1, be also provided with valve 7;
On the wall between the first protruding ring 3 and fixed lever 1 blind end, be also provided with auxiliary exhaust ports, in auxiliary exhaust ports, by relief valve 10, be connected with auxiliary gas cylinder 11, auxiliary gas cylinder 11 is open circles tubulose, in auxiliary gas cylinder 11, be provided with auxiliary piston 8, at auxiliary piston 8, between the end face of air inlet one side and auxiliary piston 8, be provided with diastole spring 9 dorsad.
When needs launch antenna, can to fixed lever inside, carry out gas injection by valve, now thereby air pressure promotes float-valve plug and promotes the expansion of damping oil realization to telescopic rod assembly, auxiliary arranging of gas cylinder can be carried out pressure release when gas injection is too fast, adjust the speed that antenna launches, prevent that antenna from damaging.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
