The often work of progress long period in the wild is needed, causes it to need in face of various complex environments, it is necessary to ensure whole antenna
Waterproof anti-corrosion ability, can so work long hours without breaking down.Pass through spiral shell between traditional antenna house and bottom plate
Tether and connect, bolt connection position has infiltration phenomenon in long-term use, causes bolt to dismantle difficulty because of rust corrosion.
The content of the invention
To overcome disadvantages mentioned above, the purpose of this utility model is to provide a kind of water resistance good GNSS antenna.
In order to reach object above, the first technical scheme that the utility model is used is：A kind of GNSS antenna, including phase
The antenna house and bottom plate connected, is provided with associated microstrip radiating element and antenna chokes in the cavity that antenna house and bottom plate surround
Groove, is connected through a screw thread between the antenna house and bottom plate；It is provided with the side wall of the bottom plate in overflow launder, the overflow launder
Portion's insertion is provided with leakage board, and the overflow launder is separated into upper dead slot and lower dead slot, the upper dead slot and set by the leakage board
There is absorbent wool, the bottom of the lower dead slot is directly connected with the base plate external.Threaded connection is made into by antenna house and bottom plate,
And Waterproof cotton progress water suction processing is placed to threaded connection place, so that the water surprisingly penetrated on antenna house be adsorbed, prevent in it
The normal work of influence GNSS antenna is oozed to cavity.Water can overflow from Waterproof cotton bottom under gravity simultaneously carries out lower sky
In groove and then outside outflow GNSS antenna.
Preferably, the height of the overflow launder lateral wall is less than itself madial wall height, the high point position of the absorbent wool
It is highly consistent with the overflow launder lateral wall.It is designed to effectively prevent the water on absorbent wool from entering in cavity by above-mentioned
Portion.
It is that the antenna cover inner surface is provided with inner edge neck, the inner edge as further improvement of the utility model
Neck matches with the overflow launder madial wall position.In GNSS antenna assembling process, overflow launder madial wall can be caught in interior
In checkpost groove, the air circulation so completely cut off between overflow launder and cavity.
Preferably, seal is provided with the inner edge neck, the seal is sticked on the inwall of inner edge neck.It is above-mentioned
It is designed to strengthen the effect that overflow launder madial wall completely cuts off air circulation, improves the antiseepage outlet capacity of GNSS antenna.
Preferably, the screw thread convergence part of the antenna house is provided with sealing ring.Above-mentioned sealing ring can strengthen GNSS antenna
Sealing effectiveness, and then improve its overall water resistance.
It is that outwardly convex formation drainage is convex at the covers edge of the antenna house as further improvement of the utility model
Rise, the drainage projection is not in contact with bottom plate.When rainwater is hit down on antenna house, the water of top can flow into drainage projection
Place, because drainage projection is not in contact with bottom plate, so as to effectively inhibit, external water enters antenna house and the screw thread of bottom plate connects
Meet place.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
In figure：
1- antenna houses；2- bottom plates；3- leakage boards；4- sealing rings；5- absorbent wools；6- associated microstrip radiating elements；7- antenna choke grooves；
8- drainages are raised；9- inner edge necks.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
With reference to shown in Fig. 1, present embodiments provide a kind of GNSS antenna, it is adaptable to be in outside work for a long time, have
Good water resistance.Specifically include the antenna house 1 and bottom plate 2 of interconnection, enclose positioned at antenna house 1 and bottom plate are 2-in-1
Associated microstrip radiating element 6 and antenna choke groove 7 are provided with cavity, antenna choke groove 7 is circumferentially positioned at the periphery of associated microstrip radiating element 6, and
The groove depth of antenna choke groove 7 gradually becomes shallower as from inside to outside so that GNSS antenna can be operated in wider working band, and suppress
Multipath interference signal of the surrounding environment to reception antenna, improves the anti-multipath effect capability of reception antenna.
As shown in figure 1, being connected through a screw thread between the antenna house 1 and bottom plate 2；Provided with excessive in the side wall of the bottom plate 2
Chute, the overflow launder middle part insertion be provided with leakage board 3, and the leakage board 3 by the overflow launder be separated into upper dead slot and
Lower dead slot, is provided with absorbent wool 5 in the upper dead slot, the bottom of the lower dead slot directly with the ft connection of bottom plate 2.Wherein it is
Strengthen the water resistance of GNSS antenna threaded connection place, the height of the overflow launder lateral wall less than itself madial wall height,
The high point position of the absorbent wool 5 and the overflow launder lateral wall are highly consistent.So absorbent wool 5 is not easy to overflow after absorbing moisture
It flow in the cavity of GNSS antenna.In the present embodiment for the water resistance of further strengthened thread junction, two sides
Structure in face of GNSS antenna is improved.
1 is improved, the inner surface of antenna house 1 is provided with inner edge neck 9, the inner edge neck 9 and overflow launder inner side
Wall position matches.In GNSS antenna assembling process, overflow launder madial wall can be caught in inner edge neck 9, so completely cut off
Air circulation between overflow launder and cavity.
Improve 2, outwardly convex formation drainage projection 8 at the covers edge of the antenna house 1, the drainage projection 8 not with
Bottom plate 2 is in contact.When rainwater is hit down on antenna house, the water of top can flow into drainage high spot, because drainage is raised not
It is in contact with bottom plate, so as to effectively inhibit external water into the threaded connection place of antenna house and bottom plate.
Furthermore, it is understood that the sealing property that seal strengthens whole GNSS antenna is employed in the present embodiment, it is above-mentioned
Seal is applied to the screw thread convergence part of inner edge neck 9 and antenna house 1.Wherein in the screw thread convergence part of antenna house 1 provided with sealing
Circle 4, for strengthening the sealing effectiveness of GNSS antenna, and then improves its overall water resistance；Glued on the inwall of interior checkpost groove 9
With seal, the effect of air circulation is completely cut off for strengthening overflow launder madial wall, the antiseepage outlet capacity of GNSS antenna is improved.
Embodiment of above is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with this skill
The people of art understands content of the present utility model and is carried out, and protection domain of the present utility model, all can not be limited with this
The equivalent change or modification done according to the utility model Spirit Essence, should all cover in protection domain of the present utility model.
