Spherical security monitoring device
Technical field
The invention belongs to technical field of security and protection, be specifically related to a kind of safety defense monitoring system spherical security monitoring device.
Technical background
Spherical security monitoring device is widely used as a kind of headend equipment of intelligent video camera, especially in the safety monitoring technical field.Existing spherical security monitoring device be light harvesting, electronics, machinery, information processing in one, form by camera, power transmission, motion control device.
Because the complexity of existing spherical security monitoring device internal structure and the continuation of operating state need take effective safeguard procedures to protect to guarantee its operate as normal usually.
Existing outdoor ball-type safety monitoring product, its connected mode as shown in Figure 1, wherein ball machine outer cover 12 upper tops have an installation apical pore that mates with installation suspension bracket 11, cable 10 is from top to bottom through installing in the suspension bracket 11, and enter the inner chamber of ball machine outer cover 12 by the apical pore of ball machine outer cover 12 upper tops, electrically connect with the PCB circuit board 13 that is installed in ball machine outer cover 12 inner chambers, suspension bracket 11 upper ends are installed to be fixed on the platform that presets, realize safety monitoring, the spherical security monitoring device of this kind structure, because ball machine internal circuit directly is connected with outside incoming line, when trachoma appearred in the installation suspension bracket, on outdoor rainy day, rainwater infiltrates by trachoma installed the suspension bracket hollow part, and in cable flows into the ball machine, damage the ball machine.
For overcoming the above problems, also has a kind of water-proof spherical video camera in the prior art, it directly draws electric line from ball machine inside, and adopt water-tight device that cable is pinned at ball machine outer cover incoming line place, be tightly connected, stop current to enter ball machine inside along cable with cable, but, there is following defective in this structure: one, water can accumulate in the slit of water-tight device and outer cover formation for a long time, and outer cover is caused damage; Its two because cable and water-tight device are installed closely, when needing repairing dismounting, rotate water-tight device, cable can rotate thereupon, thereby pulls the comparatively connecting portion of fragility of cable and internal machine core, causes damage.
In sum, it is good to develop a kind of water resistance, easy for installation, and the security monitoring device of being convenient to keep in repair has become pressing for of user.

Embodiment
Below, in conjunction with the accompanying drawings and embodiment, spherical security monitoring device of the present invention is described further:
As Fig. 2, shown in 3, be a kind of spherical security monitoring device that is installed in the outdoor open-air atmosphere of the present invention, it comprises sky shade 21, outer cover 22, clear bottom cover 24, its three all is hemispherical dome structure, outer cover 22 docks with clear bottom cover 24, and connect its two periphery by bolt, and at it the two inner forms a ccontaining cavity, be installed with plastic cement enclosing cover 25 from top to bottom at this cavity inside, movement 27, wherein movement 27 comprises the The Cloud Terrace system 271 that is positioned at its top, and the video camera 272 that is positioned at its underpart, fixed installation PCB circuit board 251 on plastic cement enclosing cover 25, The Cloud Terrace system 271 electrically connects with PCB circuit board 251, and for the ease of installing and repair demolition, it adopts the terminal ways of connecting.
As Fig. 2,3, and in conjunction with Fig. 4, above-mentioned sky shade 21 is set in the top of outer cover 22, and and outer cover 22 between form an assemblage gap B; Simultaneously, in order to realize and control the data interchange on backstage, above-mentioned spherical security monitoring device also includes cable 20, be provided with the through hole that current supply cable 20 passes on sky shade 21 tops, corresponding, being provided with a boss 221 on outer cover 22 tops, boss 221 is provided with the through hole that current supply cable 20 passes, make cable 20 ends insert in the cavity of outer cover 22 and 24 formation of clear bottom cover, and electrically connect with the PCB circuit board.
In order to realize the purpose of waterproof, the inventor is provided with downward weather board 211 at the periphery of sky shade 21 upper portion thereon through holes, the bottom face of weather board 211 is lower than the upper surface (upper surface of the through hole that passes of outer cover 22 current supply cables just) of boss 221, and its difference in height is d; Cable 20 when mounted, it is downward to pass and carry over weather board 211 by the through hole at outer cover 22 tops, walks around after the weather board 211, its trend becomes upwards, it is downward to pass the through hole that is positioned on the boss 221 subsequently, enters in the cavity that outer cover 22 and clear bottom cover 24 form; During use, rainwater para-electric cable 20 also by the through hole of sky shade 21, according to general physical general knowledge, is subjected to the influence of gravity downwards, and behind the bottom of arrival weather board 211 under the current direction, it is downward along assemblage gap B, and C shown in the figure is a flow direction.
In order further to guarantee good sealing, guarantee the operate as normal of inner member continuation of the present invention, dismounting simultaneously is easy for installation and maintenance, the inventor is equipped with waterproof cover 23 at the top of above-mentioned outer cover 22, it is fixedly connected on the last top of outer cover 22 inside by bolt 231, be provided with groove at waterproof cover 23 upper surface peripheries, groove is embedded in is equipped with sealing ring 26, its material is a soft rubber, regulates the degree that screws of bolt 231, realizes compressing rubber seal Figure 26, thereby guaranteed that waterproof cover 23 is connected with the airtight of outer cover 22, when needing repairing, then can easily open bolt 231, realize the fractionation of waterproof cover 23 and outer cover 22.
In order to realize the dustproof function; inner member is done further protection; referring to Fig. 3; the inventor is provided with dust cover 28 in the bottom of sky shade 21; dust cover 28 is positioned at the bottom of assemblage gap B, prevents that dust from entering outer cover 22 inside by assemblage gap B, simultaneously; this dust cover 28 stream that can supply water passes through, and it is outside to flow to whole device.
Among the present invention, the bottom face of weather board 211 is lower than the difference in height d of upper surface of boss 221 greater than 1cm, certainly, its concrete size can design according to the needs of external environment condition, when using in the more region of rainfall, then be designed to bigger difference in height, when using, be designed to less difference in height in the less region of rainfall.
Weather board is the platy structure with a gradient that sky shade 21 extends downwards among the present invention, according to general mechanical general knowledge, weather board in the waterproof construction of the present invention can also be as shown in Figure 5, be the downward extension 211` of through hole periphery on the sky shade 21, for fear of with the conflicting of boss 221, it has a gradient, and the bottom face of extension 211` is lower than the upper surface of boss 221, and has a difference in height.
Spherical security monitoring device of the present invention mount in suspension bracket is installed and with lead fixed good after, its core section can be dismantled arbitrarily and not influence its cable and shell is fixed, convenient for maintaining is safeguarded and the engineering staff constructs, and has shortened the duration of its installation and maintenance maintenance.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of claim of the present invention all according to technical scheme described above and design.
