Background

City management is a branch of public management. The contents of city management include public safety management, sanitation management, and the like. The public safety management is particularly important because it relates to the personal safety of citizens living in cities. For example: cameras are installed on main streets of many cities to monitor or catch criminals, so that the purpose of protecting the personal safety of citizens is achieved. When the camera is generally used indoors, the property loss is prevented, and some unnecessary disputes are avoided, for example: the mall may monitor the thief with a camera.

The supervisory equipment who now adopts usually is the camera, but the self security performance of present camera is not high, suffers artificial destruction easily, for example stealer uses the stone to pound the shell of camera bad to lead to the inside damage of camera, can't monitor indoor. Secondly, in the long-term use of camera, easy adhesion dust on the camera, and when too much dust is piled up on the camera, can shelter from the camera, and influence the shooting effect of camera, lead to the camera even can't reach the purpose of shooing the thief. No matter the camera is artificially damaged, or the accumulated dust of the camera is too much, the influence can be caused to the camera, so that the purpose of monitoring safety can not be achieved.

The principle and the beneficial effects of the invention are as follows: the periphery at the camera is set up with the drive shell to the cooling shell to form the casing that is used for the protection to the camera, traditional camera only has one deck metal casing, receives the stone or when great striking, and the camera can directly take place to warp, can't use even. This scheme can be to the further protection of camera through the protecting crust, great reduction the camera probability of artificial damage.

The operating temperature of general camera is below 50 ℃, if the camera is in the higher operational environment of temperature for a long time, leads to the damage of camera easily, and this scheme is cooled down to the camera through the water of retaining intracavity to the environment that makes the camera work is comparatively stable, has prolonged the life of camera.

Traditional camera is at outdoor work, and impurity such as a lot of dust of easy adhesion leads to the shooting effect of camera to reduce easily, consequently will remove dust to the camera. If artifical clearance, the camera is in higher position again, has certain degree of difficulty, and the efficiency of clearance is lower, and drives the drive shell through actuating mechanism in this scheme and come to store the water of intracavity and spout to and the air escape in the intracavity that removes dust, spun water and combustion gas homoenergetic remove dust to the camera, so remove dust and cool down to the camera, have obviously reduced the degree of difficulty of artifical clearance, and the efficiency of removing dust. More importantly, if the protective shell is damaged, the camera does not need to be replaced. And traditional camera suffers the destruction of casing, need change whole camera, and this scheme has reduced the replacement cost of camera.

Further, the lateral wall of cooling shell is provided with a plurality of recesses. The cold air can pass through in the recess to the recess can increase the area of contact of cooling shell and outside air, if the cooling shell collides with hard thing simultaneously, the recess can reduce the area of contact of hard thing and cooling shell, thereby reduces the damage degree of protecting crust.

The cooling rod stretches out the cooling shell, and when the camera was outdoor, can prevent birds to a certain extent to stop on the camera, so reduced the damage probability of camera. Meanwhile, water in the water storage cavity can exchange heat with external cold air through the cooling rod.

Furthermore, one end of the cooling rod close to the camera is wedge-shaped, and one end of the driving shell close to the cooling rod can be wedged with the cooling rod. When the drive shell slides towards the cooling rod, the cooling rod can provide a resistance to the drive shell, so that the drive shell is not too fast to extrude the water in the water storage cavity, the water in the water storage cavity flows out fast, the water in the water storage cavity flows out slowly, and the camera can be fully cooled by the water.

Furthermore, a channel communicated with the water storage cavity is arranged in the cooling rod, and the cooling rod is made of iron metal. Iron metal has better heat-conducting property and is cheap compared with copper metal. If meet rainy day, rainwater accessible passageway enters into the retaining intracavity and stores, so reaches the purpose of the water of replenishing the retaining intracavity.

Further, still including the controller that the control driving piece opened and close, the controller electricity is connected with the temperature sensitive sensor who is used for detecting the camera temperature. If the temperature of the working environment of the camera is detected by the temperature-sensitive sensor to be higher, the temperature-sensitive sensor can send a signal to the controller, and the controller can control the driving piece to work, so that manual operation is avoided, and the working efficiency is improved.

Furthermore, a supporting shaft is fixed on the protective shell, an articulating piece is arranged at one end, away from the protective shell, of the supporting shaft, an electric cylinder is arranged below the supporting shaft, and an output shaft of the electric cylinder is articulated with the supporting shaft. Electronic jar during operation, when the output shaft of electronic jar stretches out and promote the back shaft and upwards rotate, the back shaft area camera upwards faces upward, and the shooting angle of so camera is up. When the output shaft of electronic jar contracts, back shaft and camera rotate downwards under the effect of gravity, the shooting angle of camera like this is down. The shooting angle of the camera can be adjusted through the control of the electric cylinder.
