The all other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model embodiment provides a kind of waterproof aerial mounting structure, for by antenna body 1
It is installed in earth's surface, mounting structure includes metal cabinet 2, and the top of metal cabinet 2 is opening, should using the sealing of wave transparent top plate 22
Opening, metal cabinet 2 enclose the chamber 5 to form opposing seal with wave transparent top plate 22, and wherein metal cabinet 2 and wave transparent top plate 22 is equal
It is to adapt to the transmission of the signal of antenna body 1, inlet opening 21 is provided with the bottom of metal cabinet 2, the connection of inlet opening 21 should
Chamber 5, extraneous ponding can be entered in chamber 5 by inlet opening 21, and installed part is additionally provided with metal cabinet 2, can by installed part
Antenna body 1 is installed in chamber 5, and after the installation of antenna body 1, between the bottom surface of antenna body 1 and wave transparent top plate 22
Distance be L, and should be met some requirements between the L and the height H of metal cabinet 2,Wherein P0
For external pressure, h is the depth of accumulated water on the wave transparent top plate 22, and ρ is ponding density.In the utility model, metal cabinet 2
For the main part of mounting structure, antenna body 1 can be mounted on by installed part by metal cabinet 2 and enclosed with wave transparent top plate 22
In the chamber 5 of conjunction, antenna body 1 is close to wave transparent top plate 22, when mounting structure is placed in earth's surface, it is ensured that antenna body
1 normal signal transmission, chamber 5 is sealing in addition to inlet opening 21, certain waterproof construction is formed, when earth's surface has h depth
During ponding, due to being provided with inlet opening 21 on metal cabinet 2, ponding can be entered in chamber 5 by inlet opening 21, so that ponding
Larger seepage pressure will not be produced to metal cabinet 2, it is higher to need not have between this metal cabinet 2 and wave transparent top plate 22 etc.
The waterproof construction of level, when ponding is by the entrance of inlet opening 21 chamber 5, so that the air pressure in chamber 5 increases, and working as chamber 5
After interior liquid level reach a certain height, the internal pressure strength of chamber 5 is under poised state, i.e., ponding is difficult to go successively in chamber 5, this
When chamber 5 in liquid level and antenna body 1 bottom surface between also there is certain distance, and then ensure ponding be difficult to penetrate into antenna sheet
In body 1, detailed process refers to following analysis：
It is embedded in the metal cabinet 2 of earth's surface, height H, cross-sectional area A.Based on ideal gas behavior method, it is assumed that metal cabinet
In 2 bottom water inlet chamber 5, cause volume of air and pressure change, P in chamber 51、V1、P2、V2It is that metal cabinet 2 exists respectively
Ground and the air pressure being embedded in after the water inlet of underground and volume, i.e.
P1V1=P2V2 ①
Assuming that the bottom water-feeding deep of metal cabinet 2 is x, 1. formula of bringing into obtains,
P1HA=P2(H-x)A ②
Assuming that earth's surface has ponding in inclement weather, the depth of accumulated water on metal cabinet 2 is h, and extraneous air atmospheric pressure is
P0, according to the equal principle everywhere of pressure at liquid level in chamber 5, i.e.,
P2=P0+ρg[h+(H-x)] ③
In order to avoid water enters antenna body 1, it is desirable to the liquid level in metal cabinet 2 is less than the bottom surface of antenna body 1,
Distance of the bottom surface of antenna body 1 away from wave transparent top plate 22 is L, i.e.
H-x ＞ L are 4.
By solving, 2., 3., 4. formula can obtain the design height of metal cabinet 2 and be,
This is to sum up analyzed, when the height of metal cabinet 2When meeting the condition, outside metal cabinet 2
The ponding of side is difficult to enter in antenna body 1, i.e., can be to the antenna body 1 of installation in it using the mounting structure of this structure
Preferable waterproof action is played, and because the structure of the mounting structure is simple, classification of waterproof generally only needs IP24 i.e. than relatively low
