Background technique
The Cloud Terrace, refers to the steering shaft be connected with fixed support bottom optical device.According to its pivotal feature can be divided into can only left rotation and right rotation horizontally rotate The Cloud Terrace and can the left rotation and right rotation all-directional tripod head that can rotate up and down again.In general, horizontal rotation angle is 0 ° ~ 350 °, and vertical rotation angle is ± 90 °.The speed that horizontally rotates of constant speed The Cloud Terrace is generally at 3 ° ~ 10 °/s, and vertical speed is 4 °/about s.The speed that horizontally rotates of speed change The Cloud Terrace is generally at 0 ° ~ 32 °/s, and vertical rotary speed is at 0 ° ~ 16 °/about s.In some high speed video systems, the speed that horizontally rotates of The Cloud Terrace is up to 480 °/more than s, and vertical rotary speed is at 120 °/more than s.What the vidicon camera of monitoring and large-scale optical device used as the telescope in observatory is all electronic cradle head device.
There are two motors all-directional tripod head inside, is responsible for the rotation of the upper and lower of The Cloud Terrace and left and right all directions respectively.The difference of its operating voltage also determines the overall work voltage of this The Cloud Terrace, generally has and exchanges 24V, alternating current 220V and direct current 24V.When receiving upper and lower operation voltage, motor vertical rotates, and drives vertical-transmission wheel disc to rotate through speed reducer; When receiving left and right operation voltage, horizontal motor rotates and drives the horizontal teeth wheel disc bottom The Cloud Terrace to rotate through speed reducer.
But the existing The Cloud Terrace overwhelming majority is all outdoor application, for carrying out the sealing of The Cloud Terrace, be rotatably connected position be all adopt outside framework oil seal seal, such mode of structure brings a problem, during cloud platform rotation, frictional force is too large, cause motor load to strengthen and the response capability of motor to control signal and the instant response ability degradation to acceleration change, this is particularly outstanding on some steady picture type The Cloud Terrace.
Summary of the invention
The utility model, in order to overcome the shortcoming of above-mentioned technical problem, provides a kind of mazy type The Cloud Terrace waterproof construction with ultralow friction coefficient.
The mazy type The Cloud Terrace waterproof construction with ultralow friction coefficient of the present utility model, comprise left shell and right shell body, left shell is fixed with main shaft, right shell body is provided with the bearing matched with main shaft, left shell realizes relatively rotating with coordinating of bearing by main shaft with right shell body; Its specialization is: right shell body is provided with folding shape portion near one end of left shell, is formed and stops rainwater and the first guiding gutter of drainage between folding shape portion and right shell body; The periphery of main shaft is provided with ring baffle, is formed and stop further rainwater and the second guiding gutter of drainage between ring baffle and left shell.
The mazy type The Cloud Terrace waterproof construction with ultralow friction coefficient of the present utility model, first circuit board and second circuit board is respectively arranged with in the internal cavities of described left shell and right shell body, first circuit board is connected by connection cable with second circuit board, main shaft offers the through hole be convenient to connection cable and passed.
The mazy type The Cloud Terrace waterproof construction with ultralow friction coefficient of the present utility model, the two ends of described connection cable are electrically connected with first circuit board and second circuit board respectively by slip ring.
The beneficial effects of the utility model are: mazy type The Cloud Terrace waterproof construction of the present utility model, and left shell is matched by main shaft and bearing with right shell body, achieves and rotates relatively freely; By arranging folding shape portion on right shell body, arranging ring baffle in the periphery of main shaft, define the first guiding gutter and second guiding gutter of labyrinth shape, extraneous rainwater can be effectively avoided to enter into left shell or right shell body, the exterior edge face of bearing is sealed without the need to adding rubber ring, both solve waterproof problem, turn reduced frictional force during cloud platform rotation, add The Cloud Terrace transient response ability, simple and reasonable for structure, beneficial effect is remarkable.
Accompanying drawing explanation
Fig. 1 is the structural representation of mazy type The Cloud Terrace waterproof construction of the present utility model.
Fig. 2 is the waterproof principle figure of mazy type The Cloud Terrace waterproof construction of the present utility model.
In figure: 1 left shell, 2 main shafts, 3 bearings, 4 right shell bodies, 5 first circuit boards, 6 connection cables, 7 second circuit boards, 8 folding shape portions, 9 first guiding gutters, 10 ring baffles, 11 second guiding gutters, 12 connecting bolts.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, give the structural representation of mazy type The Cloud Terrace waterproof construction of the present utility model, it is made up of left shell 1, right shell body 4, main shaft 2, bearing 3, shown main shaft 2 is fixed on the end of left shell 1 by connecting bolt 12, bearing 3 is arranged on right shell body 4, and realize and the coordinating of main shaft 2, freely can rotate relative to right shell body 4 to realize left shell 1, can be used as substantially horizontal rotational structure or the Vertical direction rotational structure of watch-dog The Cloud Terrace.Shown left shell 1 and the inside of right shell body 4 are cavity, be respectively used to deposit first circuit board 5 and second circuit board 7, first circuit board 5 carries out signal with second circuit board 7 by connection cable 6 and is connected, and is provided with the through hole be convenient to connection cable and run through in main shaft 2.Further, by arranging slip ring at the two ends of connection cable 6, connection cable 6 being connected with second circuit board 7 with first circuit board 5 by slip ring, left shell 1 and right shell body 4 can be made to relatively rotate at any angle.
For The Cloud Terrace in the past, in order to ensure the sealing of bearing place to rainwater, can in the arranged outside rubber seal of bearing 3, although achieve sealing, but the frictional force of rubber seal and The Cloud Terrace contact segment is larger in movement process, add the load of drive motor, the respective capabilities of cloud platform rotation is declined.
And The Cloud Terrace of the present utility model, be provided with folding shape portion 8 in the end of right shell body 4, make to define the first guiding gutter 9 rainwater being carried out to drainage, in order to avoid rainwater enters in left shell 1 and right shell body 4 between folding shape portion 8 and right shell body 4.Arrange by ring baffle 10 in the periphery of main shaft 2, define the second guiding gutter 11 to the further drainage of rainwater between ring baffle 10 and left shell 1, like this, the first guiding gutter 9 and the second guiding gutter 11 just define mazy type waterproof construction.
As shown in Figure 2, give the waterproof principle figure of mazy type The Cloud Terrace waterproof construction of the present utility model, the rainwater entered by gap between left shell 1 and right shell body 4 can be discharged by the first guiding gutter 9, even if rainwater enters into the second guiding gutter 11 by the first guiding gutter 9, by the second guiding gutter to the further drainage of rainwater, discharge, rainwater can be stopped completely and entered into bearing 3 region, achieve the sealing of left shell 1 and right shell body 4.
In Fig. 2, when left shell 1 and right shell body 4 horizontal positioned, the mazy type waterproof construction formed by the first guiding gutter 9 and the second guiding gutter 11 can effectively avoid rainwater to enter; When left shell 1 and right shell body 4 are vertically placed, its waterproofing effect is better.Owing to avoiding the use of rubber seal, when left shell 1 and right shell body 4 are relatively rotated, frictional force is very little, adds the transient response ability of The Cloud Terrace.
