Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 show schematically show the overall structure comprising the watch-dog of video camera of the present embodiment.
The watch-dog of the present embodiment comprise be connected with mounting platform support, rack-mount bowl-shape adaptor 13 (as shown in Figure 3), be connected to the dome type camera on bowl-shape adaptor 13 and cover on the protective cover 15 directly over the bowl-shape adaptor 13 being connected with dome type camera.When running into sleety weather, protective cover 15 can stop sleet effectively, and prevent sleet from directly falling on the translucent cover 14 of dome type camera, thus the image definition that dome type camera collects is unaffected, picture quality is guaranteed.
Support comprises the mount pad 11 being installed to mounting platform and the suspension arm 12 be connected with mount pad 11.The free end of suspension arm 12 is provided with the screwed hole of opening towards ground.Bowl-shape adaptor 13 comprises the joint pin 131 (as shown in Figure 3) be threaded with the screwed hole on suspension arm 12 being arranged on top.Protective cover 15 comprises the through hole 154 passed for joint pin 131 being positioned at top.
When this watch-dog is installed, first the mount pad 11 of support is fixed on wall, then the through hole 154 of protective cover 15 is socketed on joint pin 131, finally joint pin 131 is screwed in the screwed hole that the free end of suspension arm 12 is arranged.Like this, protective cover 15 is fixed holding position under suspension arm 12 with the common squeezing action of exchanging structure.The protective cover 15 fixed can cover whole bowl-shape adaptor 13, but the field range of the collection image of dome type camera can not be blocked, thus protective cover 15 both can stop that sleet was directly fallen on the translucent cover 14 of dome type camera, prevent sleet from affecting the IMAQ of dome type camera environment to external world, ensure picture quality, dome type camera can not be affected again and gather image.When special season, rainwater is fallen on translucent cover 14 and can be congealed into ice, and protective cover 15 eliminates the possibility that rainwater freezes on translucent cover 14, extends the useful life of the translucent cover 14 of dome type camera.
In the present embodiment, as shown in Figure 2, protective cover 15 comprises and extending radially outwardly away from suspension arm 12 bottom margin, then towards the flange 151 that the top of protective cover turns down.Bottom margin after turnover forms guiding gutter.Flange 151 is provided with the breach 152 be connected with guiding gutter.This breach 152 is gaps.Rainwater drops onto after on protective cover 15 can be slipped to guiding gutter along the outer surface of protective cover 15.Discharge from gap after being pooled to the rainwater formation current of guiding gutter.Like this, rainwater can not directly be fallen on translucent cover 14, and also not easily blowed to the translucent cover 14 of dome type camera by strong wind from the current that gap is discharged, thus ensure that and can not to be drenched by rainwater at the translucent cover 14 of the larger weather condition lower semisphere video camera of rainfall, still can capture image clearly, enhance the adaptive capacity of watch-dog entirety.
Further, flange 151 arranges multiple gap.When running into the very large weather condition of rainfall, the rainwater in guiding gutter can be discharged by multiple gap quickly, prevent from collecting in guiding gutter the water yield excessive time rainwater overflow from other edge of flange 151 and blown to the translucent cover 14 of dome type camera by high wind.Preferably, multiple gap is evenly distributed on flange 151 along described protective cover 15 circumference, and drainage effect is better.
The outer surface of flange 151 is provided with based on gap edge outward extending protruding 153.Like this, rainwater can be discharged by the position that protruding 153 are directed to distance transparent cover 14 farther, thus reduce further the rainwater of discharging from gap can not by wind to the probability translucent cover 14.In the present embodiment, the cross section of gap is trapezoidal.
Further, as shown in Figure 3, protective cover 15 is provided with annular element 155 near the top of suspension arm 12.Through hole 154 is arranged on annular element 155.Like this, the axial dimension of through hole 154 is larger, and the area contacted with joint pin 131 is larger, and the radial location of protective cover 15 is more accurate, ensure that the reliability be connected between protective cover 15 with joint pin 131, and position skew is less likely to occur protective cover 15.Preferably, through hole 154 comprises the first shoulder hole and the second shoulder hole.The root of joint pin 131 is set to the multidiameter matched with the first shoulder hole and the second shoulder hole.Like this, the radial position of joint pin 131 pairs of protective covers 15 is formed better spacing, facilitates assembling with bowl-shape adaptor 13 quickly and accurately of protective cover 15.
As shown in Figure 4, between the step surface and the step surface of joint pin 131 of through hole 154, seal 99 is provided with.After joint pin 131 is screwed to the screwed hole that suspension arm 12 is arranged, the end face of suspension arm 12 and the step surface of joint pin 131 can be clamped the hole wall of the first shoulder hole of annular element 155 and then extrude seal 99.Seal 99 1 aspect can provide power in axial direction not easily to offset to keep the position of protective cover 15, and joint pin 131 is more reliable with coordinating of screwed hole; Ensure the sealing between protective cover 15 and bowl-shape adaptor 13 on the other hand, prevent rainwater from entering into protective cover 15 inside from this gap and flowing on the translucent cover 14 of dome type camera.Preferably, seal 99 is sealing gasket or sealing ring.
Further, the inwall of protective cover 15 is provided with reinforcement 156, improves the non-deformability of protective cover 15.
As shown in Figure 1, the distance bottom of the translucent cover 14 of dome type camera and suspension arm 12 being provided with the end face of screwed hole is H, the bottom of the translucent cover 14 of dome type camera to the bottom of protective cover 15 end face between distance h1, then the height h2 of protective cover 15 equals (H-h1).The overall dimension of protective cover 15 comprises the radius R of height h2 and protective cover 15 bottom opening.The bottom of the translucent cover 14 of dome type camera to the bottom of protective cover 15 end face between distance h1 and protective cover 15 bottom opening radius R between relation can determine according to wind speed V1 and rain speed V2, namely h1:R equals V2:V1.When h1:R is less than V2:V1, the raindrop of speed to be the wind of V2 can not be by speed V1 blow on translucent cover 14.Therefore, the overall dimension of protective cover 15 determines the rank of protective cover 15 flashing, wind proofing can be designed for h2, R dimensional parameters table of comparisons of processing and manufacturing, to carry out the protective cover 15 of processing and manufacturing different size according to the weather conditions of different regions.
The main part of protective cover 15 is configured to truncated cone shell, interception shell or cylindrical shell.Preferably, as shown in Figure 1 and Figure 2, protective cover 15 comprises the different truncated cone shell of two taperings.The tapering of superposed truncated cone shell is greater than the tapering of lower truncated conical shell.Like this, protective cover 15 can match with bowl-shape adaptor 13 better, covers the dome type camera of below.In the present embodiment, annular element 155 is arranged on the vertex of a cone of top truncated cone shell, and flange 151 is arranged on the bottom of lower truncated conical shell.
Although be described the utility model with reference to preferred embodiment, when not departing from scope of the present utility model, various improvement can be carried out to it and parts wherein can be replaced with equivalent.Especially, only otherwise there is structural hazard, the every technical characteristic mentioned in each embodiment all can combine in any way.The utility model is not limited to specific embodiment disclosed in literary composition, but comprises all technical schemes fallen in the scope of claim.
