Description
Technical field
The utility model relates to a kind of camera pan-tilt, and particularly relating to a kind of is the explosion-proof adjusting mechanism of The Cloud Terrace that is used for explosion risk gas place.
Background technology
Video monitoring is the intuitively a kind of of safety precaution, and effective and efficient manner is used widely in all trades and professions at present, such as residential quarter, highway, factory and enterprise etc.
But a lot of places in the petroleum and petrochemical industry field as oil depot, refuelling station etc., are mixed with the certain density gas that explosion hazard is arranged in the air.These places are called as the explosive area, and the electrical equipment in that install in these zones must satisfy GB3836-2000 " explosive gas atmosphere electrical installation " standard code, could guarantee the security of using.
The machine operation part of the common The Cloud Terrace that is used to install watch-dog as the power supply of rotary electric machine, does not meet GB3836-2000 about explosion-proof regulation by DC12V or AC24V, therefore can not use in the place that have explosion risk gas to exist.Can design a kind of explosion prevention function that both had, the The Cloud Terrace that be convenient to again to install, cost is low have caused relevant designer's concern in the industry.
Summary of the invention
The purpose of this utility model is just at the problems referred to above and the explosion-proof governor motion of custom-designed a kind of The Cloud Terrace, this governor motion adopts the electrical source of power of DC5V intrinsic safety motor as rotatable parts, meet national explosion-proof authentication requesting, therefore can use in explosion risk gas place.
The purpose of this utility model realizes by following scheme: the explosion-proof adjusting mechanism of this The Cloud Terrace comprise shaft collar and be arranged on the shaft collar by the support that horizontally rotates that horizontally rotates gear driven, with be installed in the vertical runing rest that horizontally rotates support upper end by the vertical rotation gear driven by rotating shaft, horizontally rotate on support and the vertical runing rest and be respectively arranged with stop means, two transmitting gears are respectively by drive power source, wherein: power source all adopts the DC5V electric machine assembly, two electric machine assemblies include motor body, reducing gear, output shaft and the driving gear that is sleeved on the output shaft by holddown spring and gland nut constitute, the electric machine assembly first is installed on the shaft collar, its driving gear with horizontally rotate gear and be meshed, electric machine assembly second is fixed on and horizontally rotates on the support, its driving gear vertical rotation gear is meshed the electric machine assembly first, the rotation of second is controlled by driving circuit.
In electric machine assembly, axle sleeve is sleeved on the output shaft by flat key, and driving gear is sleeved on the axle sleeve and by gland nut and the holddown spring of spinning on axle sleeve and adjusts its friction force, is added with gib screw between gland nut and axle sleeve, becomes flexible preventing.
Principle of work of the present utility model is: the high-speed rotation of motor is passed to motor shaft through after the deceleration of reducing gear, and motor shaft drives axle sleeve by flat key and rotates, and axle sleeve is given suit gear thereon with transmission of power again.
The rotation of driving gear drives and horizontally rotates the gear rotation in the electric machine assembly first, horizontally rotates support and horizontally rotates gear and rotate synchronously, stops operating when going to the effect motor of certain position because of stop means.Finish side-to-side movement thus.
The rotation of driving gear drives the rotation of vertical rotation gear in the electric machine assembly second, and vertical runing rest and vertical rotation gear rotate synchronously, when going to the effect of certain position because of stop means motor is stopped operating.Finish side-to-side movement thus.
When the load of motor is correct, rotates and driving gear is passed in rotation by friction force.The size of friction force depends on the degree that compresses of gland nut.
When motor load was excessive, load forces surpassed friction force, and driving gear will skid on axle sleeve, thereby the protection motor can not damage because of stall.
Advantage of the present utility model is: can guarantee the security of picture pick-up device, cost is low, and is easy for installation, is specially adapted to be mixed with in the air such as oil depot, refuelling station the occasion of the explosive dangerous gas of finite concentration.
